Summary of the Invention
Problems to be Solved by the Invention
[0004] In the structure of Patent Document 1 described above, since the charger is attached to the bottom of the recess formed in the rear floor panel, there is a possibility that sufficient rigidity of the attachment portion of the charger cannot be ensured.
[0005] An object of the present invention is to obtain a mounting structure for a vehicle charger that can enhance the rigidity of the attachment portion of the charger in a structure in which the charger is attached to a rear floor panel in which a recess is formed.
Means for Solving the Problems
[0006] The vehicle charger mounting structure according to claim 1 comprises: a rear floor panel provided at the rear of the vehicle and having a recess that is recessed toward the lower side of the vehicle; a first bracket that is curved along the periphery of the recess in the rear floor panel and fixed to the rear floor panel and has a first mounting portion on which a charger can be mounted; and a second bracket that is formed in a hat shape in cross-section and fixed to the bottom of the recess and has a second mounting portion on which a charger can be mounted, wherein one end of the first bracket is positioned to overlap in a plan view with a side member that is joined to the rear floor panel and extends in the longitudinal direction of the vehicle, and the other end of the first bracket is positioned to overlap in a plan view with a component joined to the rear floor panel. The second bracket is composed of a pair of side wall portions and an upper wall portion connecting the upper ends of the side wall portions, the second mounting portion is provided on the upper wall portion, and each of the pair of side wall portions is formed in a wave shape.
[0007] In the vehicle charger mounting structure according to claim 1, the rear floor panel has a recess that is recessed toward the lower side of the vehicle, and a first bracket is fixed to this rear floor panel. The first bracket is curved along the periphery of the recess in the rear floor panel. The first bracket also has a first mounting portion to which a charger can be attached. Furthermore, a second bracket with a hat-shaped cross-section is fixed to the bottom of the recess in the rear floor panel, and the second bracket has a second mounting portion to which a charger can be attached. As a result, the charger can be attached to the first bracket and the second bracket via the first mounting portion and the second mounting portion.
[0008] Furthermore, one end of the first bracket is positioned to overlap with the side member in a plan view, and the other end is positioned to overlap with a component joined to the rear floor panel in a plan view. As a result, even if vibrations from driving on rough roads are input to the charger, the fixing portion of the first bracket is reinforced by the side member and component joined to the rear floor panel, thereby suppressing deformation of the charger's mounting portion. Furthermore, because the side wall of the second bracket is formed in a corrugated shape, the rigidity of the second bracket can be increased compared to a configuration in which the side wall is flat.
[0009] The vehicle charger mounting structure according to claim 2 is as described in claim 1, wherein the first bracket is provided with a convex bead that extends from one end to the other end.
[0010] In the vehicle charger mounting structure according to claim 2, the rigidity of the first bracket can be increased by a convex bead that extends continuously from one end to the other end of the first bracket.
[0013] Claim 3 The vehicle charger mounting structure according to claim 1 is characterized in that the other end of the first bracket is positioned to overlap with the mounting portion of the canister in a plan view.
[0014] Claim 3 In the vehicle charger mounting structure related to this, the mounting portion of the first bracket is reinforced by utilizing the mounting portion of the canister attached to the rear floor panel. This eliminates the need to provide dedicated reinforcing members or the like.
[0015] Claim 4 The vehicles relating to this claim are as described in Claims 1 to 3 In any one of the above, the first bracket extends in the vehicle width direction, and the second bracket extends in the vehicle longitudinal direction.
[0016] Claim 4 In the vehicle in question, the extension directions of the first bracket and the second bracket intersect. This ensures that the charger's mounting position remains stable regardless of whether a load is applied to the charger's mounting portion in the longitudinal or transverse direction of the vehicle. [Effects of the Invention]
[0017] As described above, the vehicle charger mounting structure according to the present invention makes it possible to increase the rigidity of the charger mounting portion in a structure for mounting a charger to a rear floor panel in which a recess is formed. [Brief explanation of the drawing]

Mode for Carrying Out the Invention
[0019] The vehicle charger mounting structure according to the embodiment will be described with reference to the drawings. The arrow RR and arrow RH appropriately marked in each figure indicate the rear side in the vehicle front-rear direction and the right side of the vehicle facing the traveling direction in the vehicle V to which the vehicle charger mounting structure is applied, respectively. Hereinafter, when simply using the directions of front and rear, up and down, and left and right for explanation, unless otherwise specified, they indicate the front and rear in the vehicle front-rear direction, the up and down in the vehicle up-down direction, and the left and right in the vehicle width direction.
[0020] As shown in FIG. 1, a rear floor panel 10 is provided at the rear part of the vehicle V to which the vehicle charger mounting structure is applied. The rear floor panel 10 extends in the vehicle front-rear direction and the vehicle width direction with the up-down direction as the plate thickness direction, and constitutes the floor surface of the luggage compartment. Note that, as an example, the vehicle V in the present embodiment is a PHEV (Plug-in Hybrid Electric Vehicle) equipped with an engine and a motor as drive sources, but it may also be applied to a BEV (Battery Electric Vehicle) having only a motor as a drive source without an engine.
[0021] A recess 10A is formed in the rear floor panel 10. The recess 10A is recessed downward with respect to the peripheral portion 10B of the rear floor panel 10, and a step is formed between the recess 10A and the peripheral portion 10B.
[0022] Here, a first bracket 12 is fixed to the peripheral portion 10B of the rear floor panel 10, and a second bracket 14 is fixed to the recess 10A of the rear floor panel 10. Further, a charger 16 is attached to the first bracket 12 and the second bracket 14.
[0023] In this embodiment, as an example, the rear floor panel 10 is a common part for both the PHEV specification and the HEV (Hybrid Electric Vehicle) specification, which does not have a charging port. In the HEV specification, since a charger described later is not required, a spare tire or the like is stored in the recess 10A. On the other hand, in the PHEV specification, a second bracket 14 for attaching the charger 16 is fixed to the recess 10A instead of the spare tire.
[0024] The charger 16 is a device for charging a battery (not shown) installed in the vehicle V, and is configured to have a charging cable connected during charging. The charger 16 and the battery are connected by a cable (not shown), and the charger 16 is configured to be able to supply power to the battery.
[0025] The charger 16 is composed of a roughly rectangular parallelepiped body 18 and a plurality of legs 20 provided on the body 18. In this embodiment, as an example, the legs 20 are provided at each of the four corners of the body 18.
[0026] The main body 18 has two legs 20 on the right side of the vehicle, one at the front and one at the rear. The front leg 20 is positioned on the first bracket 12. The rear leg 20 is positioned on the rear floor panel 10.
[0027] On the other hand, the main body 18 has two legs 20 on the left side of the vehicle, one at the front and one at the rear. The front leg 20 is positioned on the second bracket 14. The rear leg 20 is positioned on the first bracket 12. Mounting holes are formed in each of the four legs 20, and fasteners such as bolts are inserted through these mounting holes to attach the legs 20 to the first bracket 12, the second bracket 14, and the rear floor panel 10, respectively.
[0028] (First bracket 12) As shown in Figure 2, the first bracket 12 is formed of sheet metal curved along the peripheral portion 10B of the rear floor panel 10 and extends overall in the vehicle width direction. In addition, the right-side end (one end) of the first bracket 12 extends forward along the peripheral portion 10B of the rear floor panel 10.
[0029] Here, the first bracket 12 includes a first convex bead 12A, a second convex bead 12B, and a third convex bead 12C. The first convex bead 12A is formed continuously along the outer edge of the first bracket 12 on the rear side of the vehicle, from the right end of the vehicle to the left end (the other end). Furthermore, the first convex bead 12A is formed in an uneven manner along its extending direction, and the concave portion of the first convex bead 12A is joined to the rear floor panel 10 by spot welding or the like. In addition, the left end of the first convex bead 12A is a first mounting portion 24 to which the leg portion 20 of the charger 16 can be attached.
[0030] The second convex bead 12B is formed continuously along the outer edge of the first bracket 12 on the front side of the vehicle, from the right end to the left end. In addition, the second convex bead 12B is formed in an uneven manner along the direction of extension, similar to the first convex bead 12A, and the concave portion of the second convex bead 12B is joined to the rear floor panel 10 by spot welding or the like.
[0031] The third convex bead 12C is formed between the first convex bead 12A and the second convex bead 12B on the first bracket 12, and is formed continuously along the center of the width direction of the first bracket 12 from the right end of the vehicle to the left end of the vehicle. The left end of the third convex bead 12C is a first mounting portion 22 to which the legs 20 of the charger 16 can be attached.
[0032] Here, the right-side end of the first bracket 12 is positioned to overlap with the side member 30 in a plan view. Specifically, a side member 30 extending in the longitudinal direction of the vehicle is provided on the underside of the rear floor panel 10. A pair of side members 30 are provided, one on the left and one on the right, and only the right-side side member 30 of the vehicle is shown in Figure 2.
[0033] The side member 30 comprises a lower wall portion 30A and a pair of left and right side wall portions 30B. The lower wall portion 30A extends below the rear floor panel 10 in the vehicle's longitudinal direction. The lower wall portion 30A also extends upward from both left and right ends, and the upper ends of the lower wall portion 30A form flange portions that are bent along the rear floor panel 10. These flange portions are joined to the lower surface of the rear floor panel 10, and in plan view, a portion of the flange portions overlaps with the first convex bead 12A and the second convex bead 12B of the first bracket 12.
[0034] Furthermore, the left-side end of the first bracket 12 is positioned to overlap, in a plan view, with the mounting portion of the canister joined to the rear floor panel 10. Specifically, on the underside of the rear floor panel 10, the mounting bracket 32 is provided inward in the vehicle width direction compared to the side member 30.
[0035] The mounting bracket 32 is joined to the rear floor panel 10, and a canister (not shown) is fixed to this mounting bracket 32. In addition, the front part of the mounting bracket 32 overlaps with the left-side end of the first bracket 12 in a plan view.
[0036] (Second bracket 14) A second bracket 14 is provided on the vehicle front side of the first bracket 12. The second bracket 14 is fixed to the bottom of the recess 10A of the rear floor panel 10 and extends in the vehicle's longitudinal direction. The second bracket 14 is formed in a roughly hat-shaped cross-section, with the upper side of the vehicle being convex when viewed from the vehicle's longitudinal direction.
[0037] As shown in Figure 3, the second bracket 14 is composed of a side wall portion 26, a side wall portion 28, and an upper wall portion 29. The side wall portion 26 faces the right side of the vehicle when fixed to the rear floor panel 10 and extends in the vertical and longitudinal directions of the vehicle.
[0038] Here, the side wall portion 26 is formed in a wave shape. Specifically, the side wall portion 26 has a plurality of convex beads 26A that extend vertically. Each convex bead 26A protrudes outward from the general portion of the side wall portion 26 of the second bracket 14. In addition, multiple convex beads 26A are formed at intervals in the longitudinal direction of the vehicle. In this way, the side wall portion 26A is formed in a wave shape by the plurality of convex beads 26A.
[0039] The side wall portion 28 is fixed to the rear floor panel 10 and faces the left side of the vehicle, extending in the vertical and longitudinal directions of the vehicle. Furthermore, the side wall portion 28 is formed to be shorter in the longitudinal direction of the vehicle than the side wall portion 26, and multiple convex beads 28A are formed on the side wall portion 28.
[0040] The convex beads 28A extend vertically and are formed in multiples at intervals in the longitudinal direction of the vehicle. Each convex bead 28A protrudes outward from the general portion of the side wall 28, so the side wall 28 is formed in a wave-like shape by the convex beads 28A.
[0041] The upper wall portion 29 connects the upper ends of the side wall portions 26 and 28 and extends in the vehicle width direction and the vehicle longitudinal direction. In addition, a mounting hole 29A, which serves as a second mounting portion, is formed at the rear end of the upper wall portion 29, and the legs 20 of the charger 16 are attached to the mounting hole 29A. Furthermore, a heat dissipation bracket (not shown) is attached to the front end of the upper wall portion 29.
[0042] As shown in Figure 2, the height of the upper wall portion 29 of the second bracket 14 is approximately the same as that of the first bracket 12. Therefore, even if a recess 10A is provided in the rear floor panel 10, the charger 16 can be attached to the first bracket 12 and the second bracket 14.
[0043] (action) Next, the operation of this embodiment will be explained.
[0044] According to the vehicle charger mounting structure of this embodiment, the rear floor panel 10 has a recess 10A that is recessed toward the lower side of the vehicle, and a first bracket 12 is fixed to this rear floor panel 10. The first bracket 12 is curved along the peripheral portion 10B of the recess 10A in the rear floor panel 10. The first bracket 12 also has a first mounting portion 22 and a first mounting portion 24 to which a charger 16 can be attached.
[0045] Furthermore, a second bracket 14 with a hat-shaped cross-section is fixed to the bottom of the recess 10A in the rear floor panel 10, and the second bracket 14 is equipped with a mounting hole 29A to which the charger 16 can be attached. As a result, the charger 16 can be attached to the first bracket 12 and the second bracket 14 via the first mounting portion 22, the first mounting portion 24 and the mounting hole 29A.
[0046] Furthermore, one end of the first bracket 12 is positioned to overlap with the side member 30 in a plan view, and the other end of the first bracket 12 is positioned to overlap with the canister mounting bracket 32 in a plan view. As a result, even if vibrations from driving on rough roads are input to the charger 16, the fixing portion of the first bracket 12 is reinforced by the side member 30 and mounting bracket 32 joined to the rear floor panel 10, thereby suppressing deformation of the mounting portion of the charger 16.
[0047] Furthermore, in this embodiment, the rigidity of the first bracket 12 can be increased by the first convex bead 12A, the second convex bead 12B, and the third convex bead 12C, which are continuous from one end to the other end of the first bracket 12.
[0048] Furthermore, in this embodiment, since the side walls 26 and 28 of the second bracket 14 are formed in a wave shape, the rigidity of the second bracket 14 can be increased compared to a configuration in which the side walls 26 and 28 are flat.
[0049] Furthermore, in this embodiment, the mounting portion of the first bracket 12 is reinforced using the canister mounting bracket 32 attached to the rear floor panel 10. This eliminates the need to provide dedicated reinforcing members or the like.
[0050] Furthermore, in this embodiment, the extending directions of the first bracket 12 and the second bracket 14 intersect. This ensures that the mounting state of the charger 16 can be maintained in good condition regardless of whether a load is applied to the mounting portion of the charger 16 in the vehicle's longitudinal direction or the vehicle's width direction.
[0051] In particular, since a step is provided in the rear floor panel 10 between the first bracket 12 and the second bracket 14, the rigidity of the mounting portion of the charger 16 can be increased compared to a configuration without a step. Thus, in a structure in which the charger 16 is mounted to the rear floor panel 10 in which a recess 10A is formed, the rigidity of the mounting portion of the charger 16 can be increased.
[0052] Although the vehicle charger mounting structure according to the embodiment has been described above, it goes without saying that the present invention can be implemented in various forms without departing from the spirit of the invention. For example, in the above embodiment, a structure in which the charger 16 is mounted on the right end of the rear floor panel 10 of the vehicle has been described, but the invention is not limited to this, and a structure in which the charger 16 is mounted on another part may also be used.
[0053] Furthermore, in the above embodiment, the other end of the first bracket 12 is positioned so as to overlap with the canister mounting bracket 32 in a plan view, but the invention is not limited to this, and may be positioned so as to overlap with other parts in a plan view.
[0054] Furthermore, in the above embodiment, a convex bead 26A was formed on the side wall portion 26 of the second bracket 14 and a convex bead 28A was formed on the side wall portion 28, but the embodiment is not limited to this. For example, the side wall portions 26 and 28 may be formed in a wavy shape as a whole. [Explanation of symbols]
