The protective element is cantilever mounted on the vehicle body. ADVANTAGEOUS EFFECTS OF THE INVENTION
    [006] The battery protection structure according to aspects of the present invention can suppress the increase in vehicle weight while protecting the battery when a charge is introduced into the vehicle from the rear side. BRIEF DESCRIPTION OF THE DRAWINGS
    [007] Figure 1 shows a battery protection structure in an embodiment of the present invention and is a perspective view of the state in which the battery is installed.
    [008] Figure 2 shows the battery protection structure in the modality of the present invention and is a perspective view of the state in which none is also installed.
    [009] Figure 3 is a cross-sectional view along line A-A of Figure 1.
    [010] Figure 4 is an enlarged view of the main part of Figure 3. DESCRIPTION OF MODALITIES
    [011] An embodiment of the present invention is described in detail below along with the drawings.
    [012]Note that the vehicle shown in the drawings is a vehicle that includes an engine in a drive system, such as a hybrid vehicle, an electric vehicle, or a fuel cell vehicle. Furthermore, in the drawings, the arrow FR indicates a front side of the vehicle, and the arrow RR indicates the rear side of the vehicle.
    [013] As shown in Figures 1 to 3, the paired side elements 1.1 are rearwardly arranged in the vehicle body while being spaced apart in the vehicle width direction, and a floor panel 2 is arranged on the side elements 1.1. Furthermore, the inner elements of the wheel cavity 3.3, which form the inner side surfaces of the vehicle, are arranged on both sides of the floor panel 2 in the width direction of the vehicle and a cross element 4 is arranged between the internal elements of the wheel cavity 3.3. Note that, in Figure 3, reference number 5 denotes a later suspension.
    [014] In the modality, a 7 is also arranged on the rear side of the vehicle of a rear seat 6, and a spare tire 9 is disposed in the spare tire housing part 8 formed by lowering the tread panel 2 below the battery y to low. Specifically, the battery 7 is disposed in a vehicle cabin and the spare tire 9 is disposed in the vehicle cabin so as to be positioned below the battery 7.
    [015]Battery 7 includes technique cells 10 and a battery box that houses battery cells 10. Several battery cells 10 are housed in battery box 11 and are connected in series, for example. In the embodiment, the case 11 also has an upper case 11a which mainly houses a battery controller not shown and the like and a lower case 11b which mainly houses the battery cells 11 and the like. The lower case 11b has at least one lower surface 11c facing a protective element 14 to be described later.
    [016] The battery 7 (battery box 11) is supported by the cross element 4 and the floor panel 2, which are part of the vehicle body, by means of a front fixing bracket 12 rear fixing bracket 13. In In one embodiment, the front fastening bracket 12 is made of a sheet member which has an L-shape in a side view and is fastened to the cross member 4 using bolts and the like. Furthermore, the back fixing bracket 13 is made of a rectangular barrel element which is shaped like a hat in a front view and is fixed to the floor panel 2 using flanges, pegs and the like.
    [017]Spare tire 9 is housed in the spare tire housing part 8 formed in the vehicle cab. Furthermore, the spare tire is attached to the tread panel 2 using a bolt not shown and the like. Note that disposing the spare tire 9 in the vehicle cab eliminates the need for a spare tire clamping device used to dispose the spare tire 9 outside the vehicle cab and can suppress increases in vehicle weight and maintenance cost. Furthermore, arranging the battery 7 and the spare tire 9 next to each other in the top-down direction in the vehicle cabin can suppress the height part of the battery down to a low level and ensure a space for large luggage.
    [018] As shown in Figure 3, a gap is shown between battery 7 and spare tire 9, and the protective element 14 configured to protect battery 7 of spare tire 9 is disposed in this gap. The protective element 14 has one end fixed to the cross element 4 which is part of the vehicle body, and another end arranged between the battery 7 and the spare tire 9 so as to be thus mounted overhang on the cross element 4. Specifically , the protective element 14 has attachment portions 14a formed at one end and secured to the cross member 4 and a contact portion 14b formed at the other end and configured to contact the battery box 11 when a charge is introduced into the element. protector 14. In the embodiment, the protective element 14 is made of a round barrel element that has a U-shape in a plan view that is attached to the electrically conductive 4 using flanges, dowels and the like. Note that, although the fastening parts 14a of the protective element 14 are fastened to the cross-member 4 using flanges, dowels and the like in the modality, the fastening parts 14a of the protective element 14 can be fastened to the element at 4 cross by means such as welding.
    [019] Furthermore, a bulging part 15, which bulges from the lower surface 11c of the battery box 11 towards the spare tire 9 is presented in a parts of the lower surface 11c of the battery box 11, which is expected between in contact with the contact part 14b of the protective element 14, and a hollow part is formed within the bulging part 15. As shown in Figure 4, the bulging part 15 has at least one base surface 16 facing the part. of contact 14b of the protective element 14. In the embodiment, a panel 17 is disposed on the lower surface 11 of the battery box from below, and a bead shown on the panel 17 forms the bulging portion 15.
    [020] Furthermore, a reinforcing plate 18 which reinforces the battery box 11, is disposed in the battery box 11. Specifically the reinforcing plate extends, in the upward-downward direction, from the lower box 11b to the top case 11a of the battery box. Therefore, the lower end of the reinforcing plate 18 is close to the lower surface 11c of the battery box 11, and the upper end of the reinforcing plate 18 is close to the upper surface 11d of the battery box 11. Furthermore, the distance D (see Figure 4) between the lower end of the reinforcing plate 18 and the base surface 16 of the bulging part 15 is fixed so as to be greater than the distance (in mode the distance is zero) between the lower edge of the plate of reinforcement 18 and the lower surface 11c of the battery box 11. Operations and effects of the modality are described below. (1) The battery protection structure, in the embodiment of the present invention, includes the battery 7 arranged in the vehicle cabin, the spare tire 9 arranged in the vehicle cabin so as to be positioned below the battery 7 and the protective element 14 disposed between the battery 7 and the spare tire 9. The protective element 14 has one end fixed to the cross element 4 and the other end arranged between the battery 7 and the spare tire 9 so as to be thus mounted overhang on the cross element 4.
    [021] The protective element 14 is disposed between the battery 7 and the spare tire 9. When a load is introduced into the vehicle from the rear side and the spare tire 9 moves towards the also 7, the spare tire 9 reaches the protective element 14, as shown in Figure 4. The spare tire 9 thus pushes the protective element 14 and the load from the spare tire 9 is introduced into the battery 7 via the protective element 14. Therefore, the load introduced from the spare tire 9 into the battery 7 can be effectively reduced (Effect 1).
    [022] Since the protective element 14 is mounted overhang on the cross element 4, which is part of the vehicle body, the mode of deformation of the protective element 14 in the box where the load is introduced from the spare tire 9 in the other The end of the protective element 14 is a mode in which the protective element 14 rotates around the end fixed to the cross-element 4. It is therefore possible to determine the part where the protective element 14 and the battery 7 come into contact with each other when the load is introduced from the spare tire 9 into the protective element 14, the structure of the battery 7 can be optimized and refined (Effect 2).
    [023] Effects 1 and 2, mentioned above, allow the spare tire 9 to be disposed below battery 7 in the vehicle cab with battery 7 being protected. Therefore, the entire length of the vehicle can be reduced by fixing a large superimposed length (see Figure 3) between battery 7 and spare tire 9 in the front-rear direction of the vehicle.
    [024]The increase in vehicle weight can thus be suppressed with the battery being protected when the load is introduced into the vehicle from the rear. 2.) The bulging part 15, which bulges from the lower surface 11c of the battery box 11 towards the contact part 14b of the protective element 14, is presented in the part of the lower surface 11c of the battery box with which the part of contact 14b of the protective element 14 comes into contact, and the hollow part is formed within the cambering part 15.
    [025] When the load of the spare tire 9 is introduced into the protective element 14 and the contact part 14b of the protective element 14 comes into contact with the bulging part 15 presented on the lower surface 11c of the battery box 11, so as to crush the hollow part inside the bulging part 15. Thus, the charge can be absorbed by the bulging part 15 presented on the lower surface 11c of the battery box 11. Furthermore, as described above, using a drawing in the in which the protective element 14 is mounted overhang on the cross element 4, which is part of the vehicle body, it is possible to determine the contact part between the protective element 14 and the battery 7 in case the load is introduced from the spare tire 9 in the protective element 14. In view of this, the bulging part 15 is presented in the determined contact part. The bulging part 15 shown in the battery box 11 can thus absorb the charge received from the protective element 14. The charge introduced into the battery cells 10 housed in the battery box 11 can thus be effectively suppressed. (3) The reinforcing plate 18, extending in the top-down direction, is arranged in the battery box 11, and the distance D between the lower end of the reinforcing plate 18 and the base surface 16 of the bulging part 15 is fixed so as to be greater than the distance between the lower end of the reinforcing plate 18 and the lower surface 11c of the battery box 11.
    [026] When the load of the spare tire 9 is introduced into the protective element 14 and the contact part 14b of the protective element 14 comes into contact with the battery box 11, first the contact part 14b of the protective element 14 comes into contact with the bulging part 15 presented on the lower surface 11c of the battery box 11 so as to crush the hollow part inside the bulging part 15. Then, when the hollow part inside the bulging part 15 is crumbled to some extent , the lower end of the reinforcing plate 18 arranged in the battery box 11 receives the charge from the lower surface 11c of the battery box 11. Therefore, the reinforcing plate 18 in the battery box 11 can receive and absorb the charge which is large. too much for the bulging portion 15 shown in the battery box 11 to absorb. Consequently, the charge introduced into the battery cells 10 can be more effectively suppressed.
    [027] Although the content of the present invention has been described above using the modality, the present invention is not limited to the above description. It is evident to those skilled in the art that various modifications and improvements can be made.
    [028] For example, the vehicle component disposed in the vehicle cab may be another vehicle component than the spare tire.
