Patent No. 5928365

By the way, in a vehicle equipped with a sliding door that opens and closes the entrance/exit by sliding the door along the side of the vehicle body, a battery may be disposed on the floor panel at a position adjacent to the door pocket of the sliding door. In this case, there is a possibility that the battery and a portion of the door pocket are placed at a position where they overlap when viewed from the side of the vehicle. Further, in such a vehicle, the amount of intrusion of the side sill into the inside of the vehicle increases due to the size of the sliding door. Therefore, in the event of a side collision, if the door pocket of the sliding door is deformed or displaced by the collision load, the collision load will be applied to the battery through the portion of the door pocket that overlaps with the battery, which could damage the battery. be. However, the conventional holding structure described above is not intended for the battery to be placed adjacent to the door pocket of a sliding door, so it reduces the collision load applied to the battery due to deformation or displacement of the door pocket in the event of a side collision. It was difficult to do, and there was room for improvement.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle having a sliding door, which can prevent damage to a battery placed adjacent to a door compartment on the floor panel in the event of a side collision. It is an object of the present invention to provide a battery holding structure for a battery.

In order to achieve the above object, the present invention includes a battery mounted on a floor panel of a vehicle having a sliding door at a position adjacent to a door pocket for accommodating a sliding mechanism disposed at the lower end of the sliding door. A vehicle battery holding structure for holding a battery is provided. This vehicle battery holding structure includes a door pocket side joint portion that is joined to a surface of the vertical wall portion of the door pocket that extends in the vehicle vertical direction that bulges inward of the vehicle, and a floor panel that is joined to an upper surface portion of the floor panel. The invention includes a brace having side joints and a retaining component secured to the brace and having a battery attachment portion remote from the brace. Further, the brace extends in a direction inclined toward the front side or the rear side of the vehicle as it goes inward in the vehicle width direction from the door compartment side joint part, and is mounted between the door compartment side joint part and the floor side joint part. It has been passed.

In the vehicle battery holding structure according to the present invention as described above, in the event of a side collision, when a collision load directed inward in the vehicle width direction is transmitted to the door pocket and acts on the brace through the vertical wall portion of the door pocket, the brace is moved inside the vehicle. It deforms, that is, the brace begins to fall away from the door pocket. The battery is attached to the brace with a holding part in between, and the battery is held at a distance from the brace, so even if the brace deforms toward the inside of the vehicle, there is a constant distance between the battery and the brace. will be maintained. This makes it possible to avoid contact between the battery and the door pocket during a side collision, and prevents damage to the battery due to collision load acting on the battery via the door pocket.

Furthermore, a floor side member 11 is provided on the lower surface portion 7b of the floor panel 7 and extends in the longitudinal direction of the vehicle, which is indicated by a broken line in FIG.

Among the cross members 8a to 8c, the cross member 8b located between the front seat and the rear seat has an outer end in the vehicle width direction adjacent to the bulging surface 5c of the door pocket 5. As part of the structure for attaching and holding the battery on the floor panel 7 located between this cross member 8b and the cross member 8a disposed on the front side of the vehicle than the cross member 8b, the door pocket 5 is expanded. A brace 30 is provided at a portion of the exit surface 5c located on the front side of the vehicle. A holding part 50 is fixed to the brace 30.

FIG. 2 is a perspective view showing an enlarged area A surrounded by a dashed line in FIG. Area A includes the brace 30 and the retaining part 50. Further, FIG. 3 is a plan view showing the vicinity of the brace 30 and the holding component 50 in FIG. 2 from above the vehicle. Further, FIGS. 4 to 6 are cross-sectional views taken along lines BB to DD in FIG. 3, respectively.

In FIGS. 2 to 6, the brace 30 includes a door pocket-side joint portion 31 that is joined to the bulging surface 5c of the vertical wall portion 5b of the door pocket 5, and a floor-side joint portion that is joined to the upper surface portion 7a of the floor panel 7. 32. In this embodiment, the door pocket side joint portion 31 is joined to a portion of the bulging surface 5c of the door pocket 5 on the vehicle front side. The brace 30 extends in a direction inclined toward the front of the vehicle as it goes inward in the vehicle width direction from the door pocket side joint 31 (see FIG. 3), and is installed between the door pocket side joint 31 and the floor side joint 32. It is set up to be passed on.

The floor side joint portion 32 of the brace 30 according to this embodiment is joined to the floor side member 11 via the floor panel 7, as shown in FIGS. 3 to 5. Specifically, the floor side member 11 has a hat-shaped cross section in the vehicle width direction that opens upwardly of the vehicle (see FIG. 4), and the left and right end portions 11a and 11b are connected to the floor panel 7. It is joined to the lower surface portion 7b. A convex portion 7c that protrudes toward the upper side of the vehicle is formed in a portion of the floor panel 7 located between the joint between the floor panel 7 and the floor side member 11, and the brace 30 is straddled over this convex portion 7c. A floor-side joint portion 32 is joined to the upper surface portion 7a of the floor panel 7 (see FIGS. 2 and 3). Note that the floor panel 7 is gently inclined toward the upper side of the vehicle as it goes toward the front side of the vehicle around the joint portion with the brace 30 (see FIG. 5). Therefore, in the portion where the end portion 11a (11b) of the floor side member 11 is arranged, the floor side joint portion 32 of the brace 30, the floor panel 7, and the end portion 11a (11b) of the floor side member 11 are connected. This means that three layers are joined together.

A portion 33 of the brace 30 that spans between the door pocket-side joint 31 and the floor-side joint 32 (hereinafter referred to as the "erected portion") is inclined toward the bottom of the vehicle as it goes inward in the vehicle width direction. (See Figures 2 and 4). In this embodiment, the construction part 33 of the brace 30 includes an inclined surface 33a facing above and inside the vehicle, opposing side surfaces 33b and 33c extending downward from the vehicle from both ends along the longitudinal direction of the inclined surface 33a, and an inclined surface 33a. It has an end surface 33d that extends downward from the vehicle inner side (floor side) end of the vehicle and connects the opposing side surfaces 33b and 33c. Each end of the inclined surface 33 a and the opposing side surfaces 33 b and 33 c located on the vehicle outer side (door pocket side) is connected to the door pocket side joint portion 31 . Further, each end portion of the opposing side surfaces 33b, 33c and the end surface 33d located on the inside of the vehicle (floor side) is connected to the floor side joint portion 32. Further, of the opposing side surfaces 33b and 33c, the side surface 33b located on the inside in the vehicle width direction extends from the portion of the floor side joint 32 that is joined to the floor side member 11 toward the door pocket side joint 31. The width becomes wider toward the bottom of the vehicle (see FIGS. 2 and 5). A holding component 50 is fixed to the inclined surface 33a and end surface 33d of the construction portion 33 of the brace 30 as described above.

As shown in FIGS. 2 and 3, the holding component 50 has a battery attachment portion 50a at a position remote from the brace 30. The holding component 50 in this embodiment extends in substantially the same direction as the direction in which the brace 30 extends from the door pocket side joint part 31 to the floor side joint part 32. Specifically, the holding component 50 is a plate-like member formed into a substantially L-shape (see FIGS. 4 to 6), and has an upper fixing portion 51 provided at one end in the longitudinal direction, and a lower fixing portion 51 provided at the other end. A side fixing portion 52 is provided.

The upper fixing part 51 of the holding component 50 is fixed to the inclined surface 33a of the brace 30. Further, the lower fixing portion 52 is located below the vehicle than the upper fixing portion 51, and is fixed to the end surface 33d of the brace 30. A plane part 53 and a vertical part 54 are provided between the upper fixing part 51 and the lower fixing part 52. The plane portion 53 is approximately parallel to the upper surface portion 7a of the floor panel 7 and extends from the upper fixing portion 51 toward the inside of the vehicle. The vertical surface portion 54 is substantially perpendicular to the upper surface portion 7a of the floor panel 7 and extends from the lower fixing portion 52 toward the upper side of the vehicle. The vehicle inner side end portion of the plane portion 53 and the vehicle upper side end portion of the vertical surface portion 54 are connected to each other.

A first stepped portion 53a is formed in the flat portion 53 of the holding component 50 at a position closer to the inside of the vehicle than the upper fixing portion 51 (see FIGS. 3 to 6). The first step portion 53a projects in a direction away from the brace 30, specifically, in a direction away from the inclined surface 33a of the brace 30 toward the upper side of the vehicle. The stepped surface of the first stepped portion 53a intersects with the longitudinal direction of the flat portion 53, and has, for example, a hook-shaped cross-sectional shape. The aforementioned battery mounting portion 50a is provided on the flat portion 53 located between the first step portion 53a and the vertical surface portion 54, and here, a through hole for fastening the battery with a bolt is provided on the flat portion 53. (See Figures 2 and 3).

Further, similarly to the flat part 53, the vertical part 54 also has a second stepped part 54a formed at a position above the lower fixing part 52 in the vehicle (see FIGS. 4 to 6). The second stepped portion 54a projects in a direction away from the brace 30, specifically, in a direction away from the inclined surface 33a of the brace 30 toward the inside of the vehicle. The step surface of the second step portion 54a intersects with the longitudinal direction of the vertical surface portion 54, and has, for example, a hook-shaped cross-sectional shape. By forming the second step portion 54a on the vertical surface portion 54, the second step portion 54a functions as a vulnerable portion against a collision load applied from the outside in the vehicle width direction in the event of a side collision, as will be explained in detail later. As a result, the vertical surface portion 54 of the holding component 50 is likely to be twisted and deformed.

As shown in FIG. 6 (a sectional view taken along line DD in FIG. 3), the bottom 5a of the door pocket 5 in this embodiment is separated from the bottom surface 5a ₁ and the peripheral edge of the bottom surface 5a ₁ . It has a side surface _5a2 that extends upwardly of the vehicle while being bent, and a floor side member 11 is joined to the lower side of the bottom surface _5a1 . Further, a flange portion 7d formed at the side end portion of the floor panel ₇ is joined to the lower outer side of the side surface 5a2 of the bottom portion 5a, and a flange portion 7d formed at the side end portion of the floor panel 7 is joined to the upper outer side of the side surface _5a2 of the bottom portion 5a. The lower end of the bulging surface 5c is joined.

FIG. 7 is a perspective view of the vehicle with the battery attached, viewed from diagonally above the front side of the vehicle. In FIG. 7, the battery 12 is attached to the upper surface portion 7a of the floor panel 7 via the above-described brace 30 and holding component 50, as well as battery brackets 13 and 14. Specifically, the lower surface of the battery 12 is provided with fixing parts 12a and 12b at two locations, front and rear of the end located on the outside in the vehicle width direction, and at the front and rear of the end located on the inside in the vehicle width direction. Fixing portions (not shown) are also provided at two locations.

Among the four fixing parts of the battery 12, the fixing part 12b located on the outer side in the vehicle width direction and on the rear side of the vehicle is fastened to the battery attachment part 50a of the holding part 50 with a bolt 15b. Further, a fixing part 12a located on the outside of the battery 12 in the vehicle width direction and on the front side of the vehicle is fastened to a battery bracket 13 fixed to the upper surface part 7a of the floor panel 7 with a bolt 15a. The battery bracket 13 has a hat-shaped cross section in the vehicle width direction that opens toward the bottom of the vehicle, and both left and right end portions are joined to the upper surface portion 7a of the floor panel 7. A through hole for inserting a bolt 15a is formed in the top portion located at the center of the battery bracket 13.

Furthermore, the two fixing portions of the battery 12 located on the inside in the vehicle width direction, front and rear, are fastened to the battery bracket 14 fixed to the upper surface portion 7a of the floor panel 7 with two bolts (not shown). The battery bracket 14 has a shape in which two hat-shaped cross sections in the longitudinal direction of the vehicle are opened toward the bottom of the vehicle and are lined up in front and rear, and the front and rear end portions and the center portion are joined to the upper surface portion 7a of the floor panel 7. has been done. The two tops of the battery bracket 14 located on the front side and the rear side are formed with through holes through which the two bolts are inserted, respectively.

Next, the operation of the vehicle battery holding structure according to this embodiment will be explained in detail.
When a side collision occurs in the vehicle 1 in which the battery 12 is attached to a position adjacent to the door pocket 5 of the sliding door 3 as described above, a collision load directed inward in the vehicle width direction is applied to the side of the vehicle body (side panel 2, sliding door 3, side sill 6, etc.). This collision load is transmitted from the side of the vehicle body to the door pocket 5, and further transmitted to the brace 30 via the bulging surface 5c (vertical wall portion 5b) of the door pocket 5.

At this time, since the brace 30 is formed to extend in a direction inclined toward the front of the vehicle as it goes inward in the vehicle width direction from the door pocket side joint portion 31, the brace 30 receives a collision load facing inward in the vehicle width direction. It begins to deform inside the vehicle. In other words, the brace 30 falls in a direction away from the bulging surface 5c of the door pocket 5 in the event of a side collision. The battery 12 is attached to the brace 30 with a holding part 50 interposed therebetween, and the holding part 50 is provided with a battery attachment part 50a at a position away from the brace 30. Thereby, even if the brace 30 deforms toward the inside of the vehicle, a constant distance can be maintained between the battery 12 and the brace 30. Therefore, it is possible to avoid contact between the battery 12 and the door pocket 5 during a side collision, and it is possible to prevent damage to the battery 12 due to a collision load acting on the battery 12 via the door pocket 5.

Further, in the vehicle battery holding structure of this embodiment, since the holding part 50 extends in substantially the same direction as the direction in which the brace 30 extends from the door pocket side joint part 31 to the floor side joint part 32, the brace 30 is extended in the case of a side collision. 30, the holding component 50 also falls in the direction away from the bulging surface 5c of the door pocket 5. Thereby, it becomes possible to reliably avoid contact between the battery 12 and the door pocket 5.

Furthermore, in the vehicle battery holding structure of the present embodiment, the floor side joint part 32 of the brace 30 is joined to the floor side member 11 via the floor panel 7, so that the rigidity of the floor side joint part 32 of the brace 30 is increased. is enhanced. As a result, the portion of the brace 30 on the side of the floor side joint portion 32 is less likely to deform and displace, and the portion on the side of the door pocket side joint portion 31 is relatively more deformed and displaced. Therefore, when the bulging surface 5c of the door pocket 5 is deformed and displaced during a side collision, the portion of the brace 30 on the side of the door pocket side joint 31 is mainly deformed and displaced, and the holding part 50 and battery 12 also become displaced. Therefore, the battery 12 can escape from the deformation and displacement of the bulging surface 5c of the door pocket 5 during a side collision.

In addition, since the construction portion 33 of the brace 30 is inclined toward the lower side of the vehicle as it goes inward in the vehicle width direction, the brace 30 is braced between the bulging surface 5c of the door pocket 5 and the upper surface portion 7a of the floor panel 7. shape (see Figure 6). In particular, the side surface 33b located on the inside in the vehicle width direction of the construction portion 33 extends from the portion of the floor side joint 32 where it is joined to the floor side member 11 toward the door pocket side joint 31, and the width of this side surface 33b is Since the width becomes wider toward the bottom of the vehicle, the above-mentioned brace shape can be more firmly braced in the event of a side collision. Thereby, it is possible to effectively prevent the bulging surface 5c of the door pocket 5 from falling toward the inside of the vehicle. Therefore, the synergistic effect of the increased rigidity of the floor-side joint portion 32 of the brace 30 and the brace shape makes it possible to more reliably avoid contact between the battery 12 and the door pocket 5 in the event of a side collision.

Further, in the vehicle battery holding structure of this embodiment, the holding component 50 has an upper fixing part 51, a lower fixing part 52, a flat part 53, and a vertical part 54, and the flat part 53 has a first stepped part 53a, A second step portion 54a is formed on each of the vertical surface portions 54, and a battery attachment portion 50a is provided on the flat portion 53 located between the first step portion 53a and the vertical surface portion 54, thereby making it possible to hold the battery. Deformation of the battery attachment portion 50a of the component 50 can be prevented.

Specifically, in the event of a side collision, a collision load directed inward in the vehicle width direction is transmitted to the brace 30 via the side of the vehicle body and the door pocket 5, and the collision load received by the brace 30 is transferred to the upper fixing portion 51 of the holding part 50. and is transmitted to the lower fixing section 52. A first step part 53a and a second step part 54a are provided between the upper fixing part 51 and the lower fixing part 52 and the battery attachment part 50a, and are received by the upper fixing part 51 and the lower fixing part 52. The first step portion 53a and the second step portion 54a are likely to be deformed due to the collision load.

In particular, in this embodiment, the lower fixing portion 52 of the holding component 50 is fixed to the end surface 33d of the brace 30 extending in the vehicle vertical direction, and the lower fixing portion 52 The area extends approximately below the vehicle. When a collision load directed inward in the vehicle width direction is applied to the portion of the holding component 50 that extends downwardly of the vehicle, the portion becomes torsionally deformed toward the inside of the vehicle. Specifically, when a side collision occurs at the door pocket 5, the vehicle twists and deforms counterclockwise when viewed from above (see the dashed-dotted line arrow T1 in FIG. 3), and the side collision occurs at the front side of the vehicle relative to the door pocket 5. If this occurs, it twists and deforms clockwise when viewed from above (see the dashed-dotted line arrow T2 in FIG. 3). In addition, a second stepped portion 54a is formed in a portion of the holding component 50 that extends downwardly of the vehicle, and the second stepped portion 54a becomes a fragile portion during torsional deformation, thereby reducing the vehicle width of the second stepped portion 54a. Deformation tends to occur in the outer portion.

As described above, the first step portion 53a and the second step portion 54a of the holding component 50 are likely to be deformed. This can prevent deformation of the battery attachment part 50a. Further, the battery 12 is fastened to the battery attachment portion 50a of the holding component 50 with a bolt 15b, and the bolt 15b is spaced apart from the brace 30 by a first stepped portion 53a and a second stepped portion 54a. Therefore, even if the holding component 50 is torsionally deformed due to a collision load, the brace 30 does not come into contact with the bolt 15b (see FIGS. 6 and 7). This prevents the bolts 15b from breaking in the event of a side collision, and makes it possible to retain the battery 12 in the battery mounting portion 50a of the holding component 50 even after the collision. Therefore, it is possible to prevent the battery 12 from being displaced and damaged due to a side collision.

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and various modifications and changes can be made based on the technical idea of the present invention. For example, in the embodiment described above, an example was shown in which the battery 12 is attached to a position adjacent to the door pocket 5 corresponding to the sliding door 3 on the left side when looking forward from the vehicle interior; The structure of the present invention is also effective when the battery is placed adjacent to the door pocket, or adjacent to each door pocket corresponding to the left and right sliding doors.

Further, in the embodiment described above, an example was shown in which the brace 30 is joined to the portion of the bulging surface 5c of the door pocket 5 located on the front side of the vehicle, but the brace 30 is attached to the portion of the bulging surface 5c located on the rear side of the vehicle. Bonding is also possible. When the brace 30 is provided on the vehicle rear side of the bulging surface 5c, the brace 30 is formed to extend in a direction inclined toward the vehicle rear side as it goes inward in the vehicle width direction from the door pocket side joint portion 31.

Furthermore, in the embodiment described above, an example was shown in which the holding component 50 extends in substantially the same direction as the direction in which the brace 30 extends from the door pocket side joint portion 31 to the floor side joint portion 32. Even if the battery 12 extends in a direction different from the direction shown in FIG. It is possible to avoid this.

In addition, in the embodiment described above, an example was shown in which the battery 12 is fastened to the battery attachment part 50a of the holding part 50 with the bolt 15b, but the battery 12 can be fastened to the battery holding part 50 by a method other than fastening with a bolt. Of course, it is also possible to fix it to the portion 50a.
