【Example】

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

[0008] Figures 1 to 4 show an embodiment of an automobile battery storage structure according to the present invention. be. In the figure, 1 is a van-type car, and the rear part of the car 1 has A rear floor 2 is provided. The rear floor 2 is arranged at intervals above and below. It has a double structure consisting of an upper panel 3 and a lower panel 4.

[0009] The upper panel 3 includes a raised portion 5 and a flat portion disposed along the longitudinal direction of the vehicle body. It consists of a surface portion 6, and is formed into a substantially L-shaped cross section by the rising portion 5 and the flat portion 6. has been done. Then, on the flat part 6 of the upper panel 3, there is a box body which will be described later. An upper mounting hole 7 is drilled, and an upper panel located around the periphery of this upper mounting hole 7 A flange portion 8 having a substantially U-shaped cross section is bent and formed on the flange portion 3 .

0010 The lower panel 4 also includes a front part 9 and a rear part arranged along the longitudinal direction of the vehicle body. portion 10 and a portion located between these two portions that slopes gently upward toward the rear of the vehicle body. The front part 9 has a lower mounting hole 12 for the box body, which will be described later. is bored corresponding to the upper mounting hole 7. Then, the periphery of this lower mounting hole 12 The lower panel 4, which is located at 3 is formed.

[0011] On the other hand, inside the upper and lower mounting holes 7 and 12, there is a cylindrical box body 14 with open upper and lower ends. The entire outer periphery of the box body 14 is inserted into the upper panel 3 and and the inner peripheral surfaces of the flange portions 8 and 13 of the lower panel 4 by spot welding or the like. are combined. Therefore, the upper panel 3 and the lower part near the upper and lower mounting holes 7 and 12 The panels 4 are connected via a box body 14.

0012 Above the outer periphery of the box body 14, there are a pair of left and right fasteners each having a bolt hole 15. fixed brackets 16 are attached, and the lower surfaces of these fixed brackets 16 are welded. A connecting nut 17 is fixed. The fixing bracket 16 attaches the box body 14. The flange of the upper panel 3 is connected to the upper panel 3 and the lower panel 4. It is arranged so as to come into contact with the lower surface of the portion 8.

[0013] The upper opening 14a of the box body 14 serves as a battery hole and can be removed. It is normally closed by a cap-shaped lid 18, and is used for battery maintenance, which will be described later. The lid 18 is configured to be removed and opened at the time of replacement. Therefore, the lid 18 has a tightening bolt that is threadedly engaged with the weld nut 17 of the fixed bracket 16. The box body 14 is attached to the box body 14 by a route 19 in a sealed manner. For this reason, The flange portion 8 of the panel 3 is provided with an insertion hole 20 through which the tightening bolt 19 is inserted. At the same time, the seal rubber 21 is placed around the entire circumference of the box body 14, facing the outer periphery of the box body 14. It is provided.

[0014] In addition, on the lower opening 14b side of the box body 14, there is provided a front-back length of the box body 14. A narrow battery stay 22 formed shorter than the width of the vehicle is installed along the width direction of the vehicle. ing. This battery stay 22 includes a support piece portion 24 on which a battery 23 is placed; An opposing piece 25 is formed by bending both left and right sides of the support piece 24 at approximately right angles. Then, the upper portions of these opposing pieces 25 are connected to the inner peripheral surface of the box body 14 by welding or the like. It is attached so that it protrudes further downward from the lower part of the box body 14 by fitting it together. I'm being kicked. Therefore, the box main body 14 and the battery stay 22 A battery storage box 26 for storing the battery 23 is formed (see FIG. 2). reference).

[0015] The battery 23 placed on the support piece 24 of the battery stay 22 is It is fixedly held by a battery holder 27 that holds it down. Battery The holder 27 has a substantially U-shaped cross section, and has a battery at the lower end on both left and right sides. The upper end of the holder bolt 28 attached to the wrist stay 22 is tightened and fixed with a nut 29. has been established. Therefore, the opposing piece 25 of the battery stay 22 has a hook shape. A locking hole 30 is drilled to lock the lower end of the bent holder bolt 28. The lower end of the holder bolt 28 is inserted into the locking hole 30. In addition, Figure 3 In FIG. 4, R indicates the interior of the vehicle, and O indicates the exterior of the vehicle.

[0016] In the battery storage structure of this embodiment, the upper panel constituting the rear floor 2 The box body 14 is installed between the panel 3 and the lower panel 4 through the upper and lower mounting holes 7 and 12. and close the upper opening 14a of the box body 14 to the lid 18 and the seal rubber 21. The battery stay 22 is sealed on the lower opening 14b side of the box body 14. Since it is constructed to form the battery storage box 26, it has a double structure. Maximize the space inside the vehicle interior by using the dead space on rear floor 2 It can be used as widely as possible, and can also be used to store the battery 23 and reinforce the rear floor 2. I can do that. The battery storage box 26 has a box shape. Therefore, in order to improve the rigidity of the rear floor 2, the rear floor 2 itself has high rigidity. This has an advantageous effect on reducing vibration and noise.

[0017] Although one embodiment of the present invention has been described above, the present invention is limited to the already described embodiment. It is not intended to be a complete product, and various modifications and changes may be made based on the technical concept of this invention. Ru.

[0018] For example, in the embodiment described above, one battery stay 22 is placed along the width direction of the vehicle. However, depending on the size of the battery 23 to be stored, two batteries were installed. The wrist stays 22 may be arranged in a cross shape.

[0019]

[Effect of the idea]

As mentioned above, the automotive battery storage structure according to the present invention The upper and lower panels are spaced apart vertically, and the An upper panel and a lower panel each having a mounting hole and located at the periphery of the mounting hole. A cylindrical box body is joined to the flange of the box, and the upper opening is closed to the box body. Attach the lid in a sealed state, and place the battery stay on the bottom of the box body. By installing a battery storage box that holds the battery, The dead space of the double-layered vehicle body floor is used as the installation space for the battery. This increases the comfort inside the vehicle by making use of more space inside the vehicle. can be done.

[0020] In addition, in the battery storage structure of the present invention, there is a rigidity between the upper panel and the lower panel. The box body has a highly flexible box shape, which improves the rigidity of the vehicle floor. This reduces the vibration and noise of the car body floor that occurs when the car is running. can be done. What's more, the battery storage box has a battery attached to the box itself. Since it can be easily obtained by providing a It is also economically advantageous. Furthermore, with the battery storage structure of this invention, the lid can be removed. It is possible to open the top opening of the box body, making it easy to replace the battery and and inspection can be carried out easily.
