Description

[[Technical Field]]

[0001] The present disclosure relates to a battery mounting structure for a vehicle. [[Background Art]]

[0002] Cited Document 1 describes a structure for mounting a battery under the floor of a vehicle. [[Prior Art Literature]] [[Patent Literature]]

[0003] [[Patent Document 1]] Japanese Unexamined Patent Publication No. 2020-104556 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0004] Generally, a battery is mounted to a vehicle by passing a pin through a mounting hole. However, since the position of the mounting hole can vary depending on the size of the vehicle body, it is necessary to change the mounting structure according to the size of the vehicle body.

[0005] An object of the present disclosure is to enable a battery to be mounted to a vehicle without changing the mounting structure according to the size of the vehicle body. Another object is to reduce interference from the road surface. [[Means for Solving the Problem]]

[0006] The present disclosure provides The battery mounting structure is, a battery mounting structure for mounting a battery under the floor of a vehicle And, wherein a fastening hole for mounting the battery to the vehicle body is formed, The aforementioned battery is mounted on the rear side of the vehicle, a bracket provided from the battery toward the vehicle body, 1 and A second bracket is provided on the lower surface of the rear of the vehicle body, on the vehicle front side of the fastening hole, the 1 a cell damper provided between the bracket and the Second bracket , wherein The second bracket is the from the fastening hole Front of the vehicle a mounting reference hole is formed Furthermore, the upper surface of the first bracket functions as a contact surface for the cell damper, characterized in that. [Effects of the Invention]

[0007] According to this disclosure, the battery can be installed in the vehicle without having to change the mounting structure according to the size of the vehicle body. In addition, interference from the road surface can be reduced. [Brief explanation of the drawing]

[0008] [Figure 1] This is a diagram showing the vehicle from the left side. [Figure 2] This is a diagram showing battery-equipped equipment. [Figure 3] This is a cross-sectional view showing a battery mounting structure according to an embodiment. [Modes for carrying out the invention]

[0009] Figure 1 shows vehicle 100 viewed from the left side. In Figure 1, "FR" indicates the front of the vehicle, and "UP" indicates the top of the vehicle.

[0010] For example, vehicle 100 is an electric vehicle or a hybrid vehicle. Vehicle 100 has a body 102, and a battery 104 is mounted under the floor of vehicle 100 (i.e., on the underside of the body 102). As will be described later, in this embodiment, a cell damper is used to prevent the battery 104 from hitting the body 102 due to vibrations from the road surface 106.

[0011] Figure 2 shows a battery mounting unit 108. The battery mounting unit 108 includes a battery 104 and is mounted under the floor of the vehicle 100 as shown in Figure 1. For example, the battery mounting unit 108 is mounted under the floor of the vehicle 100 by a support member 110 provided on the front side of the vehicle and a support member 112 provided on the rear side of the vehicle. For example, the support members 110 and 112 are pin-shaped members.

[0012] When the size of the vehicle 100 changes (i.e., when the wheelbase changes), the position of the mounting points (e.g., fastening holes) of the battery mounting equipment 108 changes. For example, in a vehicle with a short wheelbase, position A is the mounting point of the support member 112, while in a vehicle with a long wheelbase, position B (a position further back on the vehicle than position A) is the mounting point of the support member 112.

[0013] Figure 3 is a cross-sectional view showing a battery mounting structure 10 according to an embodiment. The battery mounting structure 10 is a structure for mounting a battery 104 under the floor of the vehicle 100 (i.e., on the underside of the vehicle body 102).

[0014] The battery mounting structure 10 includes a bracket 12. The bracket 12 is attached to the rear side of the vehicle 100 on the battery 104 and extends from the battery 104 toward the vehicle body 102. Fastening holes 14, which serve as mounting points, are formed on the upper surface of the bracket 12. When the battery 104 is attached to the vehicle body 102 in a vehicle 100 with a long wheelbase, the support member 112 is inserted into the fastening holes 14 and secured.

[0015] Bracket 16 is provided on the underside of the vehicle body 102. A mounting reference hole 18 is formed in bracket 16. When attaching the battery 104 to the vehicle body 102 in a vehicle with a short wheelbase, the support member 112 is inserted into the mounting reference hole and fixed in place. Bracket 16 is provided on the inside of the vehicle body 102 (i.e., on the front side of the vehicle 100) compared to the fastening hole 14. As a result, the mounting reference hole 18 is formed on the inside of the vehicle body 102 (i.e., on the front side of the vehicle 100) compared to the fastening hole 14.

[0016] A gap is formed between bracket 12 and bracket 16. At the location of this gap, the upper surface of bracket 12 functions as a contact surface for the cell damper 20. The cell damper 20 is provided between bracket 12 and bracket 16. By providing the cell damper 20, the reduction in rigidity caused by the overhang of bracket 12 can be suppressed. Note that the cell damper 20 is not required.

[0017] In FIG. 3, the bracket 22 is shown by a broken line. The bracket 22 is a member used before the wheelbase is extended. The mounting reference hole 18 is formed at the same position as the fastening portion formed in the bracket 22 before the extension. With this arrangement, the battery can be mounted on the vehicle 100 even when the vehicle 100 has a short wheelbase.

[0018] As described above, in the battery mounting structure 10 according to the present embodiment, the fastening hole 14 and the mounting reference hole 18 are formed. Accordingly, even if the type of battery mounting equipment 108 increases according to the length of the wheelbase, the battery 104 can be mounted to the vehicle 100 without changing the battery mounting structure 10. That is, the battery mounting equipment can be standardized. Further, by providing the cell damper 20 between the bracket 12 and the vehicle body 102, interference from the road surface 106 can be reduced. For example, even in a vehicle 100 with a reduced vehicle height, the interference from the road surface 106 can be reduced. Description of Reference Numerals
