    FIELD OF TECHNIQUE
    [001] The present invention relates to an undercarriage of vehicle body with a side impact sensor. BACKGROUND OF THE INVENTION
    [002] Patent Document 1 describes a technique in which a load transmission element protruding in a predetermined length in the width direction of the vehicle is provided on at least one of an outer side of an outer rocker panel in the width direction of the vehicle and an inner side of a rocker arm molded across the width of the vehicle, both of which correspond to a side of a seated occupant. According to the conventional technique, at the time of a side collision, a collision object hits the load transmitting element before the collision object hits the outer rocker panel so that an impact load can be transmitted faster to a side crash sensor.
    [003] Patent Document 1: Japanese Patent No. 4186967 SUMMARY OF THE INVENTION Problem to be solved by the invention:
    [004] In the conventional technique, at the time of a side collision (particularly a collision with a pole), although the load transmission element also provided between the external balancer panel and the molded balancer makes it advantageously possible to quickly transmit a load to the outer rocker panel, a sectional deformation of the rocker itself is not considered. Therefore, due to the influence of the sectional deformation of the balancer itself, the load transmission to an acceleration sensor (G sensor) disposed in a peripheral part of the balancer or in a lower part of the column is small. Given this situation, there is room for improvement of the conventional technique from the point of view of early detection.
    [005] It should be noted that there is a technique to obtain early detection by improving the detection logic of a control device, but there is a limitation in the technique in that early detection is achieved by improving the logic detection.
    [006] The present invention is obtained taking into account the above fact, and aims to provide a lower structure of a vehicle body with a side collision sensor, whose lower structure of a vehicle body can obtain early detection by improving the body structure. Means to solve the problem:
    [007] A vehicle body lower structure with a side collision sensor, according to a first aspect, includes: a rocker arm placed on an outer side of a vehicle body lower portion in the width direction of the vehicle so as to extends along the front - rear direction of the vehicle, the rocker arm having a closed section structure consisting of an outer rocker panel and an inner rocker panel such that an upper flange formed on an upper part of the outer rocker panel be joined to a top flange formed on a top of the inner rocker panel; a side collision detection sensor attached to the inner rocker arm panel or to an element attached to the inner rocker arm panel, or to a lower part of a pillar provided in a vertical position from the rocker arm in order to detect a side collision with the base in an acceleration; and a first load transmitting element placed in a closed section of the rocker so as to divide the closed section longitudinally, the first load transmitting element being configured such that a first joining portion thereof is joined in a state in which the first joint portion is sandwiched between the upper flange of the inner rocker arm panel or the lower part of the pillar and the upper flange of the outer rocker panel, and a second joint portion thereof is joined to a wall portion vertical placed on an outer side of the external rocker panel in the direction of the vehicle's width.
    [008] A vehicle body lower structure with a side collision sensor, according to a second aspect, is configured such that: in the first aspect, the first joint portion is pre-joined to the upper flange of the outer panel of rocker arm, and the second joining portion is in advance joined to the vertical wall portion of the rocker arm outer panel.
    [009] A vehicle body lower structure with a side impact sensor, according to a third aspect, is configured such that: in the first or second aspect, the first load transmission element includes one or more splined portions formed between the first joint portion and the second joint portion and have a first edge line extending in the width direction of the vehicle.
    [0010] A vehicle body undercarriage with a side collision sensor, according to a fourth aspect, is configured such that: in the third aspect, the first edge line and the side collision detection sensor are arranged side by side in the direction of vehicle width in a plan view of the vehicle.
    [0011] A vehicle body lower structure with a side collision sensor, according to a fifth aspect, is configured such that: in any one of the first to fourth aspects, the side collision detection sensor is fixed to a mounting bracket fixed in a state in which the mounting bracket is provided over the top wall portion of the inner rocker panel and a floor panel has one end joined to the top wall portion.
    [0012] A vehicle body lower structure with a side collision sensor, according to a sixth aspect, is configured such that: in any one of the first to fifth aspects, a second load transmission element protruding to out in the vehicle width direction is provided in a position superimposed to the first load transmission element in a vehicle side view on an outer surface, in the vehicle width direction, of the vertical wall portion of the rocker outer panel.
    [0013] A vehicle body lower structure with a side impact sensor, according to a seventh aspect, is configured such that: in the sixth aspect, the second load transmission element includes one or more splined portions having a second edge line that extends in the vehicle width direction along an extended direction of the first edge line.
    [0014] A lower vehicle body structure with a side collision sensor, according to an eighth aspect, is configured such that: in any one of the first to seventh aspects, respective lower flanges are formed in a lower part of the outer rocker panel and on a lower part of the inner rocker panel, and the respective lower flanges are joined together; and the first load transmitting element includes a third joint portion which is joined in a state in which the third joint portion is sandwiched between the inner rocker panel lower flange or the lower part of the pillar and the lower panel flange external rocker.
    [0015] A lower vehicle body structure with a side impact sensor, according to a ninth aspect, is configured such that: in the eighth aspect, the third joint portion is joined in advance to the lower panel flange external rocker.
    [0016] A vehicle body lower structure with a side collision sensor, according to a tenth aspect, is configured such that: in the eighth or ninth aspect, the side collision detection sensor is attached to a portion of vertical wall placed on an inner side of the inner rocker panel in the direction of vehicle width.
    [0017] An operation of the first aspect is as follows. A collision load at the time of a side collision is transmitted to the rocker arm placed on the outer side of the lower portion of the vehicle body in the width direction of the vehicle and extended along the front - rear direction of the vehicle. Since the rocker arm has a closed section structure consisting of the inner rocker panel and the outer rocker panel, the collision load is transmitted to the outer rocker panel, and then transmitted to the inner rocker panel. As a result, the collision load is transmitted from the inner rocker panel to the side collision detection sensor attached to the inner rocker panel or the like. As a result, a side collision is detected.
    [0018] In this case, in the present aspect, the first load transmission element is placed within the closed section of the rocker so as to divide the closed section in the longitudinal direction. In addition, the first joint portion of the first load transmission element is joined in a state in which the first joint portion is sandwiched between the inner rocker panel upper flange or the lower part of the pillar and the upper panel flange rocker arm, and the second joint portion is joined to the vertical wall portion placed on the outer side of the rocker arm panel in the width direction of the vehicle. Taking this situation into account, a load input to the vertical wall portion of the outer rocker panel is directly transmitted to the upper flange of the inner rocker panel or the bottom of the pillar through the first load transmitting element. As a result, detection by the side collision detection sensor is prematurely done. It should be noted that, in addition to the conventional load transmission passages, a load transmission passage through the first load transmission element is added as a load transmission passage from the outer rocker panel to the inner panel of balancer, which also contributes to early detection.
    [0019] According to the second aspect, the first joining portion of the first load transmission element is in advance joined to the upper flange of the outer rocker panel, and the second joining portion is in advance joined to the vertical wall portion of the panel external rocker. Therefore, the first load transmission element is sub-mounted to the rocker outer panel. This makes it possible to easily assemble the rocker arm.
    [0020] According to the third aspect, the first load transmission element includes one or more splined portions formed between the first joint portion and the second joint portion and has an edge line extending in the direction of the width of the vehicle. Therefore, the rigidity for a load entry in the vehicle width direction is greater. In view of this situation, a collision load input to the second joint portion from the vertical wall portion of the outer rocker panel is efficiently transmitted to the first joint portion through the first edge line formed in the portion. striated.
    [0021] According to the fourth aspect, the first edge line and the side collision detection sensor are arranged side by side in the vehicle width direction in a plan view of the vehicle. Therefore, the load transmission pass in a plan view of the vehicle is smaller.
    [0022] According to the fifth aspect, the mounting bracket is fixed in a state in which the mounting bracket is provided on the upper wall portion of the inner rocker panel and the floor panel, and the sensor detection. Side collision is fixed to the mounting bracket. Therefore, when a collision load is transmitted to the vertical wall portion of the outer rocker panel at the time of a side collision, a moment of rotation to a direction in which the first load transmitting element pivots inwardly in the direction of the vehicle width with the first joint portion being considered as a center of rotation is applied to the first load transmission element. As a result, the upper wall portion of the inner rocker panel is pushed up to an upper side of the vehicle so that the side crash detection sensor can more quickly detect a side crash state.
    [0023] According to the sixth aspect, the second load transmitting element is provided in a position superimposed on the first load transmitting element in a side view of the vehicle on the outer surface, in the vehicle width direction, of the portion of vertical wall of the rocker outer panel so that the second load transmission element extends outward in the direction of the vehicle's width. Therefore, a collision charge at the time of a side collision is first transmitted to the second charge transmitting element. That is, at a moment earlier than a moment when the collision charge is transmitted to the first load transmitting element, the collision charge is transmitted to the second load transmitting element. The collision load transmitted to the second load transmitting element is then transmitted to the first load transmitting element from the vertical wall portion of the outer rocker panel. Then, the collision load is transmitted to the inner rocker panel to be transmitted to the side collision detection sensor.
    [0024] According to the seventh aspect, the second edge line of the splined portion formed in the second load transmitting element is formed along the extended direction of the first edge line of the splined portion formed in the first load transmitting element. This allows the collision load to be transmitted between the second edge line and the first edge line, both of which have a high load transmission performance. Therefore, a transmission loss of the load can be reduced.
    [0025] According to the eighth aspect, the first load-transmitting element includes the third joint portion as well as the first joint portion and the second joint portion. The third joint portion is joined in a state in which the third joint portion is sandwiched between the lower flange of the inner rocker panel or the lower part of the pillar and the lower flange of the outer rocker panel. In view of this situation, a collision load input in the vertical wall portion of the outer rocker panel is transmitted to the first junction portion and the third junction portion from the second junction portion of the first load transmitting element . That is, the rotational moment is not applied to the first load transmitting element, and the first load transmitting element as a whole is shifted so as to move in parallel towards an inner side in the width direction. of the vehicle. As a result, a placement location of the side collision detection sensor is not limited.
    [0026] According to the ninth aspect, the third joining portion of the first load transmission element is in advance joined to the lower flange of the outer rocker panel. Therefore, the first load transmission element is sub-mounted on the rocker outer panel. This makes it possible to easily assemble the rocker arm.
    [0027] According to the tenth aspect, the side collision detection sensor is fixed to the vertical wall portion placed on the inner side of the inner rocker panel in the width direction of the vehicle. This is suitable for the eighth aspect. That is, in a case where the side collision detection sensor is disposed on the vertical wall portion of the inner rocker panel, the load transmission passage becomes larger compared to a case where the side collision detection sensor side collision is disposed on an upper wall portion side of the inner rocker panel. However, in the present aspect, a collision charge is also transmitted to the side collision detection sensor from the bottom wall portion of the inner rocker panel, so that detection by the side collision detection sensor is quickly accomplished.

Similarly, a rear door opening 24 is to be opened and closed by a rear side door (not shown) and used for placement and removal of a rear seat is formed between the center pillar 16 and the rear pillar 18.
    [0046] In the following, structures of the rocker arm 12 and the center column 16 will be described with reference to Figure 1 to Figure 3. The rocker arm 12 has a closed section structure (a structure in which a closed section 30 is formed on an inner side of the section) consisting of an outer rocker panel 26 placed on an outer side in the width direction of the vehicle and having a hat-shaped longitudinal section, and an inner rocker panel 28 placed on an inner side of the outer rocker panel 26 in the direction of the vehicle's width and having a hat-shaped longitudinal section.
    [0047] In more specific terms, as illustrated in Figure 2, the external rocker panel 26 is constituted by: a vertical wall portion 26A placed on the outside in the vehicle width direction so as to extend in a direction to up and down in a longitudinal section view; an upper wall portion 26B curved inwardly in the vehicle width direction from an upper end of the vertical wall portion 26A; a lower wall portion 26C curved inwardly in the vehicle width direction from a lower end of the vertical wall portion 26A; an upper flange 26D curved towards a vehicle support side from an inner end of the upper wall portion 26B in the vehicle width direction; and a lower flange 26E curved towards a vehicle underside from an inner end of the lower wall portion 26C in the vehicle width direction. The outer rocker panel 26 is placed so that one grip side faces the inner side in the width direction of the vehicle.
    [0048] The inner rocker panel 28 is configured in the same way as the outer rocker panel 26. That is, the inner rocker panel 28 is made up of: a vertical wall portion 28A placed on the inner side in the width direction of the vehicle so as to extend in the up and down direction of the vehicle in a longitudinal sectional view; an upper wall portion 28B curved outwardly in the widthwise direction of the vehicle from an upper end of the vertical wall portion 28A; a lower wall portion 28C curved outwardly in the vehicle width direction from a lower end of the vertical wall portion 28A; an upper flange 28D curved towards the vehicle upper side from an outer end of the upper wall portion 28B in the vehicle width direction; and a lower flange 28E curved towards the vehicle underside from an outer end of the lower wall portion 26C in the vehicle width direction. The inner rocker panel 28 is placed so that an open side faces the outer side in the width direction of the vehicle. It should be noted that an outer end 32A of a floor panel 32 in the vehicle width direction is soldered with solder points to the upper wall portion 28B of the inner rocker panel 28.

A lower portion of the center pillar outer panel 34 is formed in a skirt shape in a vehicle side view, and is soldered with solder points to the top wall portion 26B and to the vertical wall portion 26A of the rocker outer panel 26. In addition, a lower part of the center pillar inner panel 36 is also formed as a skirt in a vehicle side view, and is placed so as to traverse the closed section 30 of the rocker 12 in the up and down direction of the vehicle. . In a state in which an upper edge 36A of a lower portion of the center pillar inner panel 36 is sandwiched between the upper flange 26D of the outer rocker panel 26 and the upper flange 28D of the inner rocker panel 28, the upper edge 36A is joined to upper flanges 26D, 28D with weld points. In a state in which a lower edge 36B of the lower portion of the center pillar inner panel 36 is sandwiched between the lower flange 26E of the outer rocker panel 26 and the lower flange 28E of the inner rocker panel 28, the lower edge 36B is joined to lower flange 26E of outer rocker panel 26 and lower flange 38A of outer side panel 38 with solder points.

In addition, the boundary portions (curved portions) between the matched front and rear side walls 54A and the respective general portions 56 are second edge lines 58 which extend in the width direction of the vehicle. The second edge line 58 is placed over an extended line of the first edge line 46 of the first spline portion 42. That is, the second edge line 58 extends in the vehicle width direction along an extended direction of the first line of edge 46.

It should be noted that a general portion 56 formed at a rear portion of the projecting portion 52B in the front-rear direction of the vehicle and placed on the rear side of the vehicle with respect to the second spline portion 54 has a short length in the front-rear direction of the vehicle. , so that the general portion 56 is not formed as a splined portion.
    [0057] As illustrated in Figure 1, a side collision detection sensor 64, which is an acceleration sensor, is disposed at a predetermined position (close to a position that intersects with the top edge 36A of the bottom of the panel center pillar interior 36) of rocker inner panel 28. It should be noted that, in Figures 3 and 4, the side collision detection sensor 64 is simply illustrated as a circle. In more specific terms, the side collision detection sensor 64 is attached to the inner rocker panel 28 and the floor panel 32 by means of a metal mounting bracket 66. When viewed from the front side of the vehicle, the mount 66 is generally made in a Z-shape, and includes an intermediate portion 66C disposed horizontally, an end 66A extending outwardly in the direction of the vehicle width from the intermediate portion 66C by means of a step, and a further end. 66B extended in a diagonal direction upwards over an inner side of the intermediate part 66C in the vehicle width direction. The end 66A is secured to the top wall portion 28B of the inner rocker panel 28 with solder stitches, and the other end 66B is secured to a stepped portion 32B formed at the outer end 32A of the floor panel 32 in the width direction. of the vehicle with soldering points. In that case, the mounting bracket 66 is provided on the upper wall portion 28B of the inner rocker panel 28 and on an outer side (the stepped portion 32B), in the vehicle width direction, of an overall surface of the floor panel. 32 so as to be fixed on both. Side collision detection sensor 64 is attached to intermediate portion 66C of mounting bracket 66.
    [0058] In addition, the side collision detection sensor 64 is arranged side by side, in the width direction of the vehicle, with the first edge line 46 of the first spline portion 42 disposed on a front side away from the first spline portions paired fronts and rears 42 formed in the body portion 40A of the first load transmission element 40 in a plan view of the vehicle. Operation and Effect of Present Mode An operation and effect of the present mode are described below.
    [0059] At the time of a side collision with a colliding object, such as a pole, that is, when the opening of the front door 22 collides with the colliding object in a position closer to the central pillar 16, a collision charge at that time it is transmitted to the protruding portion 52B of the second load transmitting element 52 which extends outwardly in the widthwise direction of the vehicle from the rocker outer panel 26. Since the second front and rear splined portions match 54, whose longitudinal direction is along the width direction of the vehicle, are formed in the projecting portion 52B, the collision load is mainly transmitted to the vertical wall portion 26A of the outer rocker panel 26 through the second edge lines 58 of the second portions splines 54 (a load transmission passage at this time is indicated by an arrow A in Figure 1).
    [0060] In this case, the first load transmission element 40 is arranged within the closed section 30 of the rocker 12 so as to divide the closed section 30 in the longitudinal direction. The first joint portion 40B of the first load transmission element 40 is joined in a state in which the first joint portion 40B is sandwiched between the upper flange 26D of the outer rocker panel 26 and the upper flange 28D of the inner rocker panel 28, and the second joint portion 40C is joined to the intermediate part, in the height direction, of the vertical wall portion 26A of the outer rocker panel 26. In addition, the first splined portions 42, whose longitudinal direction is along the direction. of vehicle width, are formed in the body portion 40A, and the second edge lines 58 are placed over the extended direction of the first edge lines 46. In the above configuration, the collision load input into the vertical wall portion 26A of the outer rocker panel 26 is directly transmitted to the upper flange 28D of the inner rocker panel 28 to a lesser extent through the first edge lines 46 of the first static portions. 42 formed in the first load transmission element 40 (a load transmission passage at that time is indicated by an arrow B in Figure 1). Then, the collision load transmitted to an edge line from a bottom of the upper flange 28D of the inner rocker panel 28 passes through the upper wall portion 28B of the inner rocker panel 28 (a load transmission passage at this time is indicated by an arrow C in Figure 1), and then the collision load is transmitted to the mounting bracket 66, the one end of which 66A is fixed to the upper wall portion 28B, and further to the collision detection sensor. side 64 (a load transmission passage at this time is indicated by an arrow D in Figure 1). As a result, detection by the side collision detection sensor 64 is done earlier. That is, according to the present modality, it is possible to obtain an early detection by improving the body structure.
    [0061] It should be noted that, in addition to the conventional load transmission passages (the load transmission passages at this time are indicated by arrows O, P in Figure 1), load transmission passages (arrows A ^ B ^ C ^ D in Figure 1) through the first load transmitting element 40 are added as the load transmitting passage from the outer rocker panel 26 to the inner rocker panel 28, which also contributes to early detection. Furthermore, by applying the present framework, the effect of an early detection can be expected on an ECU side arranged in a floor tunnel.
    [0062] In addition, the first joint portion 40B of the first load transmission element 40 is pre-joined to the upper flange 26D of the rocker outer panel 26, and the second joint portion 40C is pre-joined to the vertical wall portion 26A of the outer rocker panel 26. Therefore, the first load transmitting element 40 is sub-assembled before on one side of outer rocker panel 26. This makes it possible to easily carry out the mounting of the rocker arm 12. As a result, according to In the present embodiment, it is possible to successfully maintain the productivity of the lower portion of vehicle body 10 and eventually of the entire vehicle body.
    [0063] Furthermore, the first load transmission element 40 is provided with a plurality of first splined portions 42 having first edge lines 46 extending in the vehicle width direction between the first joint portion 40B and the second 40C junction portion. Therefore, the stiffness for a load entry in the vehicle width direction becomes greater. In view of this situation, a collision load transmitted to the second junction portion 40C from the vertical wall portion 26A of the outer rocker panel 26 is efficiently transmitted to the first junction portion 40B through the first formed edge lines 46 in the first spline portions 42. As a result, according to the present embodiment, it is possible to further improve the load transmission performance of the side impact detection sensor 64.
    [0064] In addition, the first edge lines 46 and the side collision detection sensor 64 are placed side by side in the vehicle width direction in a plan view of the vehicle, so that the load transmission passage is smaller in the top view of the vehicle. Consequently, according to the present embodiment, it is possible to further shorten a detection time of the side collision detection sensor 64.
    [0065] Furthermore, the mounting bracket 66 is fixed in a state in which the mounting bracket 66 is provided on the upper wall portion 28B of the inner rocker panel 28 and the floor panel 32, and the sensor of Side collision detection 64 is fixed to mounting bracket 66. In view of this situation, when a collision load is transmitted to the vertical wall portion 26A of the outer rocker panel 26 at the moment of a side collision, a moment of rotation M (see Figure 1) in a direction in which the first load transmission element 40 pivots inwardly towards the width of the vehicle, with the first joint portion 40B being considered as the center of rotation, is applied to the first element of load transmission 40. Therefore, the upper wall portion 28B of the inner rocker panel 28 is pushed to the upper side of the vehicle, so that the side collision detection sensor 64 can more quickly detect a coarse state. lateral smoothing. As a result, according to the present embodiment, it is possible to advance a detection moment particularly in a case in which the side collision detection sensor 64 is an acceleration sensor.
    [0066] In addition, the second load transmitting element 52 is provided in a position superimposed on the first load transmitting element 40 in a vehicle side view, on the outer surface, in the vehicle width direction, of the vehicle portion. vertical wall 26A of outer rocker panel 26 so that the second load transmitting element 52 extends outwardly in the width direction of the vehicle. Therefore, a collision charge at the time of a side collision is transmitted first to the second load transmitting element 52. That is, at a moment earlier than a moment at which the collision charge is transmitted to the first element of load transmission 40, the collision load is transmitted to the second load transmitting element 52. The collision load transmitted to the second load transmitting element 52 is then transmitted to the first load transmitting element 40 from the vertical wall portion 26A of the outer rocker panel 26. Then, the collision charge is transmitted to the inner rocker panel 28 so as to be transmitted to the side collision detection sensor 64. As a result of according to the present modality, it is also possible to obtain an early detection.
    [0067] In addition, the second edge lines 58 of the second spline portions 54 formed in the second load transmission element 52 are formed along the extended direction of the first edge lines 46 of the first spline portions 42 formed in the first transmission element load 40. This allows the collision load to be transmitted between the second edge lines 58 and the first edge lines 46, which have a high load transmission performance. Therefore, a transmission loss of the load can be reduced. As a result, according to the present embodiment, it is possible to effectively improve the load transmission performance of the side collision detection sensor 64 together with the first load transmission element 40. Second Mode
    [0068] Referring to Figure 6, the following describes a second embodiment of the lower structure of a vehicle body with a side impact sensor according to the present invention. It should be noted that the constituent parts of the first modality have the same reference signs as the first modality, and a description of them will be omitted.
    [0069] As illustrated in Figure 6, in the second embodiment, an outer end 70A of a floor panel 70 in the vehicle width direction is soldered with spots to a vertical wall portion 28A of an inner rocker panel 28 A mounting bracket 72 is disposed above the floor panel 70 and the vertical wall portion 28A of the inner rocker panel 28. More specifically, the mounting bracket 72 has generally the same structure as the bracket. mount 66 described in the first embodiment, and includes an end 72A, another end 72B, and an intermediate portion 72C. End 72A is secured to vertical wall portion 28A of inner rocker panel 28 with solder points. In addition, the other end 72B is attached to an outer surface, in the vehicle width direction, of an overall surface of a floor panel 70 (a part near an end 70A) with solder points. A side collision detection sensor 76 is attached to the middle portion 72C of the mounting bracket 72.
    [0070] Taking this situation into account, a first load transmission element 74 has a hat shape that is open inwards towards the width of the vehicle. That is, the first load transmission element 74 includes a lower body portion 74D, and a third junction portion 74E, in addition to a first junction portion 40B, a body portion 40A, and a second junction portion 40C with the same configuration as the first mode. It should be noted that, in the description below, the body portion 40A of the first load transmitting element 74 is referred to as the "upper body portion 40A", considering the fact that the body portion 40A forms a pair with the 74D lower body portion. Lower body portion 74D is placed on a vehicle underside with respect to upper body portion 40A. In addition, a tilt direction of the lower body portion 74D is an inverse direction to a tilt direction of the upper body portion 40A. Furthermore, in a position illustrated in Figure 6, in a state in which the third joint portion 74E is sandwiched between a lower edge 36B of a lower portion of a center pillar inner panel 36 and a lower flange 26E of an outer panel of rocker arm 26, the third joint portion 74E is joined thereto along with a lower flange 38A of an outer side panel 38. Operation and Effect of the Present Modality
    [0071] According to the above configuration, the first load transmitting element 74 includes the lower body portion 74D and the third joint portion 74E in addition to the first joint portion 40B, the upper body portion 40A, and the second 40C junction portion. Furthermore, the third joint portion 74E is joined in a state in which the third joint portion 74E is sandwiched between the lower flange 28E of the inner rocker panel 28 and the lower flange 26E of the outer rocker panel 26. in this situation, at the time of a side collision with a colliding object such as a pole, a colliding load input in a protruding portion 52B of a second load transmitting element 52 is mainly transmitted to the vertical wall portion 26A of the rocker outer panel 26 through the second edge lines 58 of the second spline portions 54 (a load transmission passage at this time is indicated by an arrow A in Figure 6). Thereafter, the collision load is transmitted to the upper body portion 40A of the first load transmitting element 40 (a load transmitting passage at that time is indicated by an arrow B in Figure 6). Load transmitted to an upper body portion side 40A is transmitted to an upper wall portion side 28B of inner rocker panel 28 via first junction portion 40B (a load transmission passage at this time is indicated by a arrow C in Figure 6). Then, the load is transmitted to the side collision detection sensor 76 (a load transmission passage at that time is indicated by an arrow F in Figure 6) through the vertical wall portion 28A (a load transmission passage therein. moment is indicated by an arrow E in Figure 6).
    [0072] In parallel, a load inlet from a side of recessed splined portion 60 and a side of protruding splined portion 62 formed in the front and rear parts of the second splined portion 54 out of the collision load transmitted to the protruding portion 52B of the second load transmission element 52 is transmitted from the vertical wall portion 26A of the rocker outer panel 26 to the lower body portion 74D (a load transmission passage at that time is indicated by an arrow G in Figure 6) . Then, the load is transmitted to a lower wall portion 28C side of the inner rocker panel 28 via the third junction portion 74E (a load transmission passage at this time is indicated by an arrow H in Figure 6). Then, the load is transmitted to the side collision detection sensor 76 (a load transmission passage at that time is indicated by arrow F in Figure 6) through the vertical wall portion 28A (a load transmission passage at that time is indicated by an arrow I in Figure 6).
    [0073] Therefore, even in the present embodiment, the collision load at the time of the side collision is directly applied, to a lesser extent, to the upper wall portion 28B and the lower wall portion 28C of the inner rocker panel 28 through the upper body portion 40A and lower body portion 74D of the first load transmitting element 74, so that the collision load can finally be transmitted to the side collision detection sensor 76. In view of this situation, accordingly with the present embodiment, detection by the side collision detection sensor 76 is done earlier than in the case of a conventional structure. That is, even according to the present modality, it is possible to obtain an early detection by improving a body structure.
    [0074] It should be noted that, in addition to the conventional load transmission passages (the load transmission passages at this time are indicated by arrows O, P and arrows Q, R in Figure 6), the load transmission passages ( arrows A ---> B ---> C ---> E ---> F and arrows A ---> G ---> H ---> I ---> F in Figure 6) through of the first load transmitting member 74 are added as the load transmitting passage from the outer rocker panel 26 to the inner rocker panel 28, which also contributes to early detection.
    [0075] In addition, the first load transmission element 74 has a hat-shaped molded section so that the first junction portion 40B and the third junction portion 74E are joined to an upper end and a lower end of the balancer 12. Therefore, unlike the first embodiment, a rotational moment M with the first joint portion 40B being considered as a center of rotation is not applied, and the first load-transmitting element as a whole 74 is shifted accordingly. to move in parallel towards an inner side in the direction of vehicle width. As a result, a placement location of the side collision detection sensor 76 is not limited. In view of this situation, according to the present embodiment, a degree of freedom in placing the side collision detection sensor 76 could be greater, so that the side collision detection sensor 76 can be applied to more types of vehicles .
    [0076] Furthermore, since the third junction portion 74E of the first load transmitting element 74 is pre-joined to the lower flange 26E of the outer rocker panel 26, the first load transmitting element 74 is sub-assembled beforehand. -partly on one side of external panel of balancer 26. This makes it possible to easily carry out the assembly of the balancer 12. As a result, according to the present embodiment, it is possible to successfully maintain the productivity of the lower portion of vehicle body 10 and eventually the entire vehicle body.
    [0077] Furthermore, the side collision detection sensor 76 is fixed to the vertical wall portion 28A placed on the inner side, in the vehicle width direction, of the inner rocker panel 28 by means of the mounting bracket 72. , the side collision detection sensor 76 is more suitable for the first load transmitting element 74 having a generally hat-shaped section than the first load transmitting element 40 having a generally hat section. Z-shape of the first mode. In other words, in a case where the side collision detection sensor 76 is placed so that it is not polarized on either side in the up and down direction of the vehicle with respect to a sectional shape of the inner rocker panel 28 (in a case where the side collision detection sensor 76 is placed close to an intermediate part, in the up and down direction of the vehicle, of the inner rocker panel 28), it is effective if directly transmitting a collision load at the time of a side impact to both the upper wall portion 28B and the lower wall portion 28C of the inner rocker panel 28 equally in a smaller passage. Furthermore, in contrast, in a case in which the side collision detection sensor 76 is disposed on the vertical wall portion 28A of the inner rocker panel 28, the load transmission passage becomes longer than in a case in which the side collision detection sensor 64 is disposed on the upper wall portion 28B side of the inner rocker panel 28. However, in the present embodiment, a collision charge is also transmitted to the side collision detection sensor. 76 from the bottom wall portion 28C of the inner rocker panel 28, so that detection by the side impact detection sensor 76 is quickly accomplished. In view of this situation, according to the present embodiment, particularly in a case in which the outer end 70A of the floor panel 70 in the vehicle width direction is joined to the vertical wall portion 28A of the inner rocker panel 28, -if possible to obtain an early detection.
