Summary of the invention

[0003] However, when the battery is placed between the frames, the minimum ground clearance of the vehicle becomes lower. Therefore, although the battery is placed on the upper side of the frame, the vehicle body (carriage or deck) is mounted on the upper side of the frame in a frame vehicle. Therefore, when the battery is to be repaired (replaced), the vehicle body needs to be removed from the frame each time, which makes the operation very cumbersome.

[0004] Therefore, an object of the present invention is to provide a battery mounting structure in a frame vehicle that enables maintenance of the battery without removing the vehicle body from the frame.

[0005] In order to achieve the above-mentioned object, a battery mounting structure in a frame vehicle according to a first aspect of the present invention comprises:

[0026] First embodiment

[0027] First, the first embodiment will be described. Figure 1A , Figure 1B As shown in FIG. 1 , the frame vehicle 12 having the battery mounting structure 10 according to the first embodiment is, for example, equipped with a battery 50 (see also FIG. 1 ). Figure 2 , Figure 3 ) of a hybrid Sport Utility Vehicle (SUV). Figure 1B , Figure 2 , Figure 3 As shown, the frame vehicle 12 includes a frame 14 to which a vehicle body 20 is attached from above. The frame 14 includes a pair of left and right side rails 16 extending in the front-rear direction.

[0028] Front wheels 22 (see FIG. 1 ) are arranged on the outer sides of the front and rear sides of each longitudinal beam 16 in the vehicle width direction. Figure 1A) and the rear wheel 24. Therefore, the dimensions of the front and rear sides of each longitudinal beam 16 in the vehicle width direction are set shorter than the dimensions of the center side in the vehicle width direction, thereby avoiding interference with the front wheel 22 and the rear wheel 24. In addition, since the front and rear sides of each longitudinal beam 16 are provided with a suspension unit (not shown) and the like on the lower side, they are provided on the upper side than the center side (see Figure 1B , Figure 2 ).

[0029] In addition, a front bumper reinforcement (not shown) extending substantially in the vehicle width direction is mounted on the front end of each side member 16, and a rear bumper reinforcement 18 (see FIG. 1 ) extending substantially in the vehicle width direction is mounted on the rear end of each side member 16. Figure 3 ).

[0030] A plurality of cross members 17 extending in the vehicle width direction are provided between the longitudinal beams 16 between the front bumper reinforcement and the rear bumper reinforcement 18 (see FIG. Figure 1B ). In other words, the plurality of cross members 17 extend in the vehicle width direction and connect the longitudinal beams 16. Thus, a ladder-shaped frame 14 is formed. Furthermore, a car body 20 is installed on the upper side of the frame 14 (see Figure 1B ).

[0031] In the frame vehicle 12 having the above frame 14 and the vehicle body 20, as shown in FIG. Figure 1B , Figure 2 , Figure 3 As shown in the figure, the battery 50 is arranged substantially horizontally on the upper side of the rear portion of the frame 14. In addition, the floor panel 30 having a substantially hat-shaped shape is arranged on the upper side of the battery 50 when viewed from the side in the vehicle width direction. In other words, a storage portion (storage space) S for storing the battery 50 is formed between the frame 14 and the floor panel 30.

[0032] A spare tire 26 is disposed at the lower side of the rear portion of the frame 14. The spare tire 26 is disposed obliquely so that the front side is lower and the rear side is higher when viewed from the side (see FIG. Figure 2 ) In addition, the floor panel 30 is formed of a metal plate, and the third row seat 28 is arranged on the upper side of the floor panel 30 .

[0033] The vehicle width direction outer side end portion 30A of the floor panel 30 is configured not to overlap with the battery 50 when viewed from the side. In other words, the lower surface of the vehicle width direction outer side end portion 30A of the floor panel 30 is located above the upper surface of the battery 50 when viewed from the front-rear direction (see FIG. Figure 3). Thus, the battery 50 is configured to be inserted and removed from the outside in the vehicle width direction relative to the storage portion S. In addition, the vehicle width direction outside end portion 30A shown in the figure is formed in a substantially "L" shape that is inclined obliquely outward and upward (outward and upward in the vehicle width direction) when viewed from the front-rear direction.

[0034] A fender liner 32 as an example of a cover member is detachably mounted on the vehicle width direction outer side of the battery 50 relative to the vehicle cabin 20. The vehicle width direction inner side end of the fender liner 32 is detachably mounted on the lower surface of the vehicle width direction outer side end 30A of the floor panel 30.

[0035] Furthermore, a bumper cover 34 (see also FIG. 1 ) as an example of a cover member is detachably mounted on the vehicle width direction outer side of the battery 50 (fender lining 32) with respect to the vehicle cabin 20. Figure 1A ) In addition, "mounted in a detachable manner" in the first embodiment means being mounted with bolts, clamps, etc.

[0036] Next, the operation of the battery mounting structure 10 in the frame vehicle 12 according to the first embodiment having the above-described structure will be described.

[0037] As described above, the battery 50 is arranged on the upper side of the frame 14 to which the vehicle cabin 20 is attached from the upper side (the storage portion S between the frame 14 and the floor panel 30), and the bumper cover 34 and the fender lining 32, which are configured to be detachable from the vehicle cabin 20, are arranged on the vehicle width direction outer side of the battery 50. In addition, the vehicle width direction outer side end 30A of the floor panel 30 does not overlap with the battery 50 when viewed from the side (is located on the upper side of the upper surface of the battery 50 when viewed from the front-rear direction).

[0038] Therefore, by removing at least the bumper cover 34 and the fender lining 32 from the vehicle cabin 20, the outer side of the battery 50 in the vehicle width direction is opened. That is, even if the floor panel 30 is arranged above the battery 50, by removing the bumper cover 34 and the fender lining 32 from the vehicle cabin 20, the battery 50 can be pulled out to the outer side in the vehicle width direction (the battery 50 can be removed from the frame vehicle 12).

[0039] In this way, according to the first embodiment, in the frame vehicle 12, the battery 50 can be accessed from the outer side in the vehicle width direction. Therefore, the battery 50 can be repaired (replaced) without removing the vehicle cabin 20 from the frame 14. Moreover, the cover components removed from the vehicle cabin 20 include the fender liner 32 and the bumper cover 34 mounted on the vehicle cabin 20 by a clip or the like. Therefore, the operation of removing these components from the vehicle cabin 20 can be easily achieved.

[0040] In addition, when the maintenance (replacement) of the battery 50 is completed, the battery 50 can be inserted into the storage portion S from the outside in the vehicle width direction. Then, the fender liner 32 is mounted on the vehicle cabin 20, and the bumper cover 34 is mounted on the vehicle cabin 20. In this way, according to the first embodiment, the frame vehicle 12 can be restored to its original state without removing the vehicle cabin 20 from the frame 14.

[0041] Second embodiment

[0042] Next, the second embodiment will be described. Note that the same reference numerals are used for the same parts as those of the first embodiment, and detailed descriptions thereof will be omitted as appropriate.

[0043] like Figures 4 to 6 As shown in FIG. 1 , the frame vehicle 12 having the battery mounting structure 10 according to the second embodiment is, for example, equipped with a battery 50 (see FIG. 1 ). Figure 5 , Figure 6 ) hybrid pickup truck. Figure 5 , Figure 6 As shown, a plurality of (eg, five) deck reinforcements 46 having different heights in a side view are detachably mounted on the upper surfaces of the pair of left and right longitudinal beams 16 .

[0044] Each deck reinforcement 46 is formed by connecting the corners of a bottom plate 46B and a top plate 46U, which are substantially rectangular flat plates, with four pillars 46S in the shape of quadrangular columns. The top plates 46U of each deck reinforcement 46, to which the lower surface of the bottom plate 46B is attached at predetermined intervals in the front-rear direction on each longitudinal beam 16, form a single surface when viewed from the side, and the top plates 46U of each deck reinforcement 46 are detachably attached to the lower surface of the bottom plate 42 in the deck (cargo bed) 40 as a part of the vehicle body.

[0045] That is, the heights of the deck reinforcements 46 are set according to the shapes of the longitudinal beams 16 so that the upper surfaces of the top plates 46U are aligned in a plane when viewed from the side. The bottom plate 42 of the deck 40 is horizontally supported on the longitudinal beams 16 via the deck reinforcements 46. In addition, the battery 50 is mounted in the space between the frame 14 (longitudinal beam 16) and the bottom plate 42 when viewed from the side. That is, the space between the frame 14 and the bottom plate 42 becomes a storage portion S in which the battery 50 is stored.

[0046] Furthermore, a deck rear panel 36 as an example of a cover member constituting the rear panel of the deck 40 is attached to the rear side of the rearmost deck reinforcement 46 so as to be detachable from the deck 40. Furthermore, a bumper cover 37 as an example of a cover member is attached to the lower side of the deck rear panel 36 so as to be detachable from the deck 40 (see FIG. Figure 4 ).

[0047] In addition, the deck reinforcement 46 is disposed on the vehicle width direction outer side with respect to the side plate 44 of the deck 40 (see Figure 6 ) is detachably mounted with a fender 38 as an example of a cover member (see Figure 4 , Figure 6 ). In addition, the side plate 44 of the deck 40 is formed integrally with the bottom plate 42 of the deck 40. In addition, "mounted in a detachable manner" in the second embodiment means mounting with bolts or clamps, etc., similarly to the first embodiment described above.

[0048] Next, the operation of the battery mounting structure 10 in the frame vehicle 12 according to the second embodiment configured as above will be described. In addition, the description of the operation common to the first embodiment will be appropriately omitted.

[0049] As described above, the battery 50 is arranged on the upper side (the storage portion S between the frame 14 and the bottom plate 42 of the deck 40) of the frame 14 to which the deck 40 is mounted via the deck reinforcement 46. The deck rear panel 36 and the bumper cover 37, which are configured to be detachable from the deck 40, are arranged on the rear side of the battery 50.

[0050] Therefore, the rear side of the battery 50 is opened by removing at least the rear panel 36 and the bumper cover 37 from the deck 40. In other words, by removing the rear panel 36 and the bumper cover 37 from the deck 40, the battery 50 can be pulled out to the rear side (the battery 50 can be removed from the frame vehicle 12).

[0051] In this way, according to the second embodiment, in the frame vehicle 12, the battery 50 can be accessed from the rear side. Therefore, the battery 50 can be repaired (replaced) without removing the deck 40 from the frame 14. Moreover, the cover components removed from the deck 40 include the deck rear panel 36 and the bumper cover 37 mounted on the deck 40 by a clamp or the like. Therefore, the operation of removing these components from the deck 40 can be easily achieved.

[0052] In addition, when the maintenance (replacement) of the battery 50 is completed, the battery 50 can be inserted into the storage portion S from the rear side. Then, the bumper cover 37 is mounted on the deck 40, and the deck rear panel 36 is mounted on the deck 40. In this way, according to the second embodiment, the frame vehicle 12 can be restored to its original state without removing the deck 40 from the frame 14.

[0053] Furthermore, in the second embodiment, the fender 38 can be removed from the side panel 44 of the deck 40, and the deck reinforcement 46 can also be removed from the longitudinal beam 16 and the bottom plate 42 of the deck 40. Therefore, if the fender 38 is removed from the side panel 44 of the deck 40, and the three deck reinforcements 46 on the center side in the front-to-back direction except for the front end side and the rear end side of the five deck reinforcements 46 arranged side by side in the front-to-back direction are removed from between the longitudinal beam 16 and the bottom plate 42 of the deck 40, the outer side of the battery 50 in the vehicle width direction is also opened.

[0054] That is, the length of the battery 50 in the front-to-back direction is set to be less than the distance between the rear surface of the front-most deck reinforcement 46 and the front surface of the rear-most deck reinforcement 46 when viewed from the side. Therefore, by removing the fender 38 from the side plate 44 of the deck 40 and removing the three deck reinforcements 46 on the center side in the front-to-back direction from between the longitudinal beam 16 and the bottom plate 42 of the deck 40, the battery 50 can be pulled outward in the vehicle width direction.

[0055] In this way, according to the second embodiment, in the frame vehicle 12, the battery 50 can also be approached from the outside in the vehicle width direction. Therefore, the battery 50 can be repaired (replaced) without removing the deck 40 from the frame 14. In addition, when the repair (replacement) of the battery 50 is completed, the battery 50 is inserted into the storage portion S from the outside in the vehicle width direction. Then, the three deck reinforcements 46 on the central side in the front-rear direction are installed between the longitudinal beam 16 and the bottom plate 42 of the deck 40, and the fender 38 is installed on the side plate 44 of the deck 40.

[0056] Although the battery mounting structure 10 in the frame vehicle 12 involved in the present embodiment is described above based on the drawings, the battery mounting structure 10 in the frame vehicle 12 involved in the present embodiment is not limited to the structure shown in the drawings, and appropriate design changes can be made without departing from the scope of the present invention.

[0057] For example, the frame vehicle 12 in this embodiment is not limited to a hybrid electric vehicle, but may be a plug-in hybrid electric vehicle (PHEV) or a battery electric vehicle (BEV). In addition, the frame vehicle 12 in this embodiment is not limited to the SUV or pickup truck shown in the figure, but may be other models.
