    Technical problem In the technology described in Document Patent 1, in order to eliminate damage to a battery intended to operate a vehicle in the event of a side collision, the battery intended to operate the vehicle is installed between a pair of rails front seat. However, at present there is a demand not only to protect the power supply device, but also to avoid damaging the cables extending from the power supply device. Since cable damage can also lead to electrical leaks, it is necessary to take thorough preventive measures which also take into account the deformation of the vehicle at the time of the collision.

    Description of the Embodiments A vehicle power supply fixing structure according to one aspect of the present invention is a vehicle power supply fixing structure comprising: an energy supply device which is arranged on the right or left side on a floor panel of a vehicle and has an interior side, relative to the width of the vehicle, from which extends a predetermined cable; and an interior mounting bracket for securing an interior side portion, relative to the width of the vehicle, of the power supply device to a floor panel, and the interior mounting bracket includes: a connection portion to the mounting device power supply connected to the power supply device; a folded portion which is folded downward from the inner side in the width direction of the vehicle from the connection portion to the power supply device; and a floor connection part which is formed at one end of a part extending from the folded part and which is connected to the floor panel.
    With the above configuration, for example, if a collision load is applied to the power supply device from the outside in the direction of the width of the vehicle at the time of a lateral collision, the support of internal flambé fixing at the folded part located between the connection part to the power supply device and the connection part to the floor, and the energy supply device moves so as to collapse towards the panel interior floor in the width direction of the vehicle. In many cases, the cable extending from the interior side in the vehicle width direction of the power supply device is routed to the floor panel on the interior side of the vehicle and is directed to another location. If the displacement is a collapsing displacement of the above energy supply device to the floor panel on the interior side in the direction of the width of the vehicle, in comparison with a displacement of displacement from the floor panel, it is possible to redirect a collision load while protecting the cable from damage, without pulling the cable.
    The structure for fixing the power supply of the vehicle may further comprise: a front cross member extending on the front side of the vehicle of the power supply device, the floor panel in the width direction of the vehicle; a rear cross member extending on the rear side of the vehicle of the power supply device, the floor panel in the width direction of the vehicle; a front exterior support which is connected to a front part of the power supply device on the exterior side in the width direction of the vehicle and to one or both of the floor panel and the front cross member; and a rear external support which is connected to a rear part of the power supply device on the external side in the direction of the width of the vehicle and to one or both of the floor panel and the rear cross member, and, among the walls located on the side of the energy supply device of one or both of the front cross member and the rear cross member, a predetermined fragile part which is more fragile than its vicinity is formed on the internal side in the direction of the width of the vehicle in relation to the front exterior support and the rear exterior support.
    With the above configuration, if a collision load is applied to the front and rear cross members from the outside in the direction of the width of the vehicle, due to the formation of the fragile part, the front cross member deforms and projects towards the front of the vehicle from the fragile part, and the rear cross member deforms and projects towards the rear of the vehicle from the fragile part. As a result, the area surrounded by the front cross member and the rear cross member is widened backward and forward. In particular, since the fragile part is formed on the inside in the direction of the width of the vehicle with respect to the front external support and to the rear external support, the fragile part can deform gently as much as possible, avoiding the influence of the rigidity of each support. The deformation of these crosspieces allows a collision load to be redirected without interfering with the aforementioned slump displacement of the energy supply device.
    The above power supply device can also be arranged under the seat on the floor panel, and the vehicle power supply fixing structure can also include a plurality of rail supports provided on the front cross member and rear cross member and which extend above the power supply device and support a pair of left and right seat slide rails.
    The above sliding rails can be inclined inwards in the direction of the width of the vehicle by a load applied from the outside in the direction of the width of the vehicle. Since the sliding rails are provided on the upper side, even if the energy supply device is lifted from the floor panel, the cover or the covering covering the energy supply device interferes with the sliding rails and this displacement is prevented. As a result, it is possible to prevent the movement of the power supply device in the direction in which the cable is pulled and to promote the above-mentioned collapse movement.
    [Embodiments] [0020] Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

It should be noted that the elements constituting substantially identical functions and configurations are designated by identical reference numbers in the present description and in the drawings, and thus a redundant description has not been made. In addition, the illustration of elements which are not directly relevant to the present invention has been omitted.
    The LIG. 1 is a perspective view showing a location for implementing a vehicle power supply fixing structure (hereinafter called fixing structure 100) according to an embodiment of the present invention. Below, in all drawings of this application, including the LIG. 1, Γ front and Γ rear of the vehicle are respectively illustrated by the arrows AV (Front) and AR (REAR), the left and right in the direction of the width of the vehicle are respectively illustrated by G (Left) and D (Right) and the top and bottom in the vertical direction of the vehicle are respectively illustrated using the arrows H (Top) and B (Bottom).
    The fixing structure 100 mainly aims to fix an energy supply device (a battery 106 in LIG. 2) to a floor panel 104 under a seat 102 on the right side of the front row in the passenger compartment. vehicle. In addition, the fixing structure 100 has a particular function of suppressing damage caused to the battery 106 and to the cables 124 in the event of a vehicle collision, in particular in the event of a lateral collision.
    The LIG. 2 is a view showing the outline of the fixing structure 100 according to the embodiment of the present invention. The LIG. 2A is a perspective view of the LIG. 1 from above the rear side of the vehicle, in which the seat 102 is removed. The fixing structure 100 is produced with the battery 106 and various fixing supports for supporting this battery 106.
    On the floor panel 104, a central tunnel 110 is provided in the center in the direction of the width of the vehicle, and a lateral threshold 112 is provided at an edge (for example a straight edge) in the direction the width of the vehicle. In addition, a front cross member 114 and a rear cross member 116 are provided on the floor panel 104, extending from the central tunnel 110 to the lateral threshold 112 in the direction of the width of the vehicle. The front cross member 114 and the rear cross member 116 are provided with a pair of left and right sliding rails 120a and 120b for the seat via a plurality of rail supports 118a, 118b. On the right side of the floor panel 104, the battery 106 is arranged in the area surrounded by the front cross member 114, the rear cross member 116 and the sliding rails 120a and 120b.
    The battery 106 is a type of power supply device and provides electricity to electronic devices such as a motor. The battery 106 is approximately rectangular, is covered with a battery cover 122 from the top side and is installed on the floor panel 104 by a plurality of supports described below. A plurality of cables 124 extends from an interior side of the battery 106 in the direction of the width of the vehicle (hereinafter, abbreviated as "interior side of the vehicle"). Cables 124 are routed from the battery 106 to the floor panel 104 on the interior side of the vehicle and are routed to another location. In addition, for example, a converter or the like (not shown) is arranged as another power supply device also on the left side of the floor panel 104. Although the technical idea of the fixing structure 100 is to fix and protect the battery 106, it can also be applied to the fixing and protection of the energy supply device, such as the converter, on the left side in the direction of the width of the vehicle.
    FIG. 2B is a representation of FIG. 2A in which the battery 106 is removed. As supports for supporting the battery 106, an interior mounting bracket 126, a front exterior support 128 and a rear exterior support 130 are used. The interior mounting bracket 126 is a component for attaching an interior portion, relative to the width of the vehicle, of the battery 106 to the floor panel 104. The exterior front support 128 is installed on the wall surface of the front crossmember 114. The front external support 128 supports the front part on the external side of the battery 106 across the width of the vehicle (hereinafter, abbreviated as "vehicle external side") on the floor panel 104 via the front cross member 114. The rear exterior support 130 is installed against the floor panel 104 and the rear cross member 116 and supports the rear part of the vehicle exterior side of the battery 106.
    FIG. 3 is an enlarged perspective view of the battery 106 and the supports of FIG. 2A. FIG. 3A is a view of the battery 106 from the top and right of the rear side of the vehicle. The upper surface of the battery 106 is covered with a battery cover 122, and the side surfaces and the like of the battery 106 are covered with the protective reinforcement 123 or the like.
    FIG. 3B is a view showing the supports of FIG. 3A through the battery 106 and the like. The interior fixing support 126 is provided with a connection part to the floor 132 which is connected to the floor panel 104 (see FIG. 2B) and with a connection part to the power supply device 134 which is connected to the battery 106. The connection part to the floor 132 is slightly wider and is connected to the floor panel 104 by means of a weld, fixing means or the like. The connection part to the electrical energy supply device 134 is formed in a curved upward position relative to the connection part to the floor 132, and is connected to the lower reinforcement and the like of the battery 106 by welding, means for fixing or the like.
    The front external support 128 is installed from the upper surface to the wall surface (rear wall) of the front cross member 114 (see FIG. 2B). The front external support 128 has a curved shape towards the rear of the vehicle from the front cross member 114 and is connected to a reinforcement or the like on the lateral surface of the battery 106 on the vehicle external side and on the vehicle front side by welding, fixing means or the like.
    The rear exterior support 130 comprises an upper support 130a on its upper side and a lower support 130b on its lower side, and is arranged in a rear part on the vehicle exterior side of the battery 106. The upper support 130a supports the battery 106 while maintaining the reinforcement or the like with the lower support 130b. The lower support 130b is coupled to the upper support 130a and is installed on the floor panel 104 (see FIG. 2B) and the lower edge of the rear cross member 116 by welding, fixing means or the like.
    FIG. 4 is a view schematically showing the movement of the battery 106 when the vehicle body deforms at the time of a vehicle collision. FIG. 4A is a view of the battery 106 of FIG. 2A from the rear of the vehicle. The interior mounting bracket 126 supports the battery 106 on the floor panel 104 and serves to protect the battery 106 and the cables 124 from damage during a vehicle collision.
    FIG. 4B is an enlarged view of the vicinity of the interior mounting bracket 126 of FIG. 4A. Seen from the rear side of the vehicle, the connection portion to the power supply device 134 of the interior mounting bracket 126 extends along the bottom side of the battery 106, and the interior mounting bracket 126 is folded at the level from a top fold portion 136 to the floor panel 104 on the underside of the vehicle interior. The interior fastening support 126 has an inclined region extending from the apex fold portion 136, is folded again at the valley pleat portion 138 provided at the end of the extended region and has the portion of connection to the floor 132 in a shape along the floor panel 104. The interior fixing bracket 126 has a plurality of folded parts, such as the top fold part 136 and the valley fold part 138, and the like. Consequently, the interior fixing support 126 has a structure which is easily deformed if an impact load (a PI load in FIG. 4A) is applied from outside the vehicle at the time of a lateral collision.
    As an example of a vehicle collision, it is assumed that a lateral collision with a pole such as a telegraph pole or the like occurs, that is to say a so-called lateral collision of a post arises. As shown in FIG. 4A, if a PI load is applied to the vehicle from the right side, first of all, the lateral threshold 112 is deformed on the interior side of the vehicle.
    As shown in FIG. 4B, if a PI load from the exterior side of the vehicle is applied to the battery support member 106, including the interior mounting bracket 126, the top fold portion 136 and the valley fold portion 138 of the support internal fixing 126 blaze so as to bend in the direction of the arrow P2 in the manner of a bellows. As a result, the PI charge is redirected and the battery 106 is protected. Likewise, by means of the internal fixing hook 126 which soars and redirects the load, the internal fixing support 126 remains connected to the floor panel 104 and to the battery 106, and can thus hold the battery 106 on the floor panel. 104.
    The buckling of the interior fixing support 126 moves the battery 106 in the direction of the arrow P2 and sags the battery 106 towards the floor panel 104 inside the vehicle. As illustrated in LIG. 2A, the cables 124 are routed from the battery 106 to the floor panel 104 on the interior side of the vehicle and are directed to another location. In the case of a movement in which the battery 106 is collapsed in the floor panel 104 on the interior side of the vehicle, the cables 124 are not drawn relative to the movement in which the battery 106 is distant from the floor panel 104. As a result, cables 124 are protected from damage, and a collision load can be appropriately redirected.
    The LIG. 5 is a view showing cross members on the front and rear sides of the LIG. 2B in different directions. The LIG. 5A shows the front cross member 114 from the rear of the vehicle. In the fastening structure 100, each cross member is provided with a fragile part which can easily deform at the time of a collision. On the battery side wall surface of the front cross member 114, i.e. the rear wall, for example, a thin elliptical part having a long axis in the width direction of the vehicle is formed as a brittle part 140 which is more fragile than its neighborhood. The fragile part 140 can be realized as a configuration in which a load is easily concentrated or of a configuration in which the rigidity is reduced, such as a notch or a recess, in addition to the thinning.
    The LIG. 5B is a view of the front cross member 114 and the rear cross member 116 of the LIG. 2B seen from above. As a fragile part 142, a thinned part is also formed on the front wall, which is a battery side wall, of the rear crossmember 116. With this configuration, if a PI load, which is a collision load, is applied from outside in the direction of the width of the vehicle, for example, the front cross member 114 deforms into a <type and protrudes towards the front of the vehicle as indicated by the arrow P3 from the fragile part 140. In addition, the rear cross member 116 deforms into a shape similar to a <and projects towards the rear side of the vehicle, as indicated by the arrow P4 from the fragile part 142. Consequently, the area surrounded by the front cross member 114 and the rear cross member 116 is widened rearward and forward.
    The fragile parts 140 and 142 are formed on the inner side in the direction of the width of the vehicle relative to the front external support 128 and to the rear external support 130. For this reason, the front cross member 114 and the rear cross member 116 are less subject to the rigidity of the front external support 128 and of the rear external support 130, and can be deformed regularly. In addition, because the connection points between the front external support 128 and the rear external support 130 and the battery 106 are present between the front cross member 114 and the rear cross member 116, the collapsed displacement of the battery 106 mentioned above. above is not prevented.
    Due to the deformation of the front cross member 114, the front external support 128 and the rear external support 130 arranged on the outside of the vehicle with respect to the fragile parts 140 and 142 are slightly displaced towards the inside of the vehicle. Consequently, the deformation of the front crossmember 114 can assist the movement of collapse of the battery 106 mentioned above, and can contribute to redirecting a collision load applied to the battery 106.
    It should be noted that, in the fixing structure 100, the fragile parts 140 and 142 are respectively provided on the front cross member 114 and the rear cross member 116, but a configuration in which a fragile part is provided on one among the front cross member 114 and the rear cross member 116 can also be used to absorb a collision load.
    In the fixing structure 100, the rail supports 118a, 118b also serve to absorb a collision load. Among the plurality of rail supports, the rail supports 118a and 118b on the exterior side of the vehicle are respectively provided on the front cross member 114 and the rear cross member 116 on the exterior side of the vehicle with respect to the fragile parts 140 and 142, at the external support front 128 and rear exterior support 130.
    As shown in FIG. 4A, the rail support 118a extends above the battery 106 and supports the sliding rail 120a (the same is true for the rail support 118b of FIG. 5B). The sliding rail 120a is arranged above the front cross member 114 and the rear cross member 116 and extends in the front-rear direction.
    As shown in FIG. 5A, if a load PI is applied to the sliding rail 120a, the sliding rail 120a moves so as to tilt towards the interior of the vehicle. Because the slide rail 120a is present on the upper side, even if the battery 106 is lifted from the floor panel 104, such movement is prevented because the battery cover 122 interferes with the slide rail 120a. Due to the inclination of the sliding rail 120a, the outer parts of the front cross member 114 and the rear cross member 116 are deformed in the upward direction of rotation indicated by the arrow P5. In parallel with this deformation, the vehicle exterior side of the battery 106 also tends to move upward, and the above-mentioned sagging displacement occurs on the vehicle interior side of the battery 106. As a result, the lifting of the battery 106 from the floor panel 104 on the interior side of the vehicle is prevented. Also with these confi gurations, movement of the battery 106 in the direction in which the cables 124 are pulled is prevented. As a result, a PI load is appropriately reoriented by the above-mentioned slump displacement.
    As mentioned above, in the fixing structure 100, the movement of the battery 106 when the vehicle body is deformed is guided in the direction of collapse in the floor panel 104 on the interior side of the vehicle by the function of the interior fixing support 126 and the like. With these configurations, in the fixing structure 100, the battery 106 is not in contact with any other structure from the start to the end of the deformation of the vehicle body at the time of a vehicle collision. Consequently, it is possible to prevent the displacement of the battery 106 in the direction in which the cables 124 are drawn and to suppress the breaking of the cables 124.
    Although preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it should be noted that the present invention is not limited to the embodiments described above. It will be apparent to those skilled in the art that various modifications and variations can be made within the scope of the invention as defined in the appended claims and that these modifications and variations should be understood to be included within the technical scope of the present invention .
