Abstract

A battery tray and a vehicle include a frame structure including a plurality of frames sequentially connected end to end arranged to be connected to the vehicle, and a base plate structure including an inner base plate and a reinforcing beam, wherein the inner base plate is located on an inner side of the reinforcing beam and arranged for mounting a battery module. The battery tray further includes a reinforcing block, wherein the reinforcing block is connected to a corresponding frame and the reinforcing beam in a matching mode, so as to fixedly connect the reinforcing beam to the frame structure through the reinforcing block. In the battery tray, the strength of the battery tray can be enhanced and a total weight can be decreased only by using the reinforcing block to fixedly connect the reinforcing beam to the frame structure.

First claim

What is claimed is:

1. A battery tray, comprising:
a frame structure, comprising a plurality of frames sequentially connected end to end, and arranged to be connected to a vehicle; and
a base plate structure, comprising an inner base plate and a reinforcing beam, the inner base plate being located on an inner side of the reinforcing beam and arranged for mounting a battery module, and the inner base plate and the reinforcing beam being fixed inside the frame structure; and
the battery tray further comprising:
a reinforcing block, a first end of the reinforcing block being connected to a corresponding frame in a matching mode, and a second end of the reinforcing block being connected to the reinforcing beam in a matching mode, so as to fixedly connect the reinforcing beam to the frame structure through the reinforcing block, wherein the first end of the reinforcing block is connected to the corresponding frame in a concave-convex fit mode.

2. The battery tray according to claim 1 , wherein the first end of the reinforcing block is provided with a first step portion, a first groove is formed in the first step portion, and the corresponding frame is provided with a first protrusion matching the first groove.

3. The battery tray according to claim 2 , wherein the top surface of the reinforcing block is flush with a top surface of the frame provided with the first protrusion.

4. The battery tray according to claim 2 , wherein the bottom surface of the reinforcing block is flush with a bottom surface of the frame provided with the first protrusion.

5. The battery tray according to claim 1 , wherein the second end of the reinforcing block is connected to an end of the reinforcing beam in a concave-convex fit mode.

6. The battery tray according to claim 5 , wherein the second end of the reinforcing block is provided with a second upper step portion, a second upper groove is formed in the second upper step portion, and the end of the reinforcing beam is provided with a second upper protrusion matching the second upper groove.

7. The battery tray according to claim 6 , wherein a top surface of the reinforcing block is flush with a top surface of the reinforcing beam provided with the second upper protrusion.

8. The battery tray according to claim 5 , wherein the second end of the reinforcing block is further provided with a second lower step portion, a second lower groove is formed in the second lower step portion, and the end of the reinforcing beam is provided with a second lower protrusion matching the second lower groove.

9. The battery tray according to claim 8 , wherein a bottom surface of the reinforcing block is flush with a bottom surface of the reinforcing beam provided with the second lower protrusion.

10. The battery tray according to claim 1 , wherein the inner base plate is provided with a plurality of inner recesses arranged to accommodate the battery module.

11. The battery tray according to claim 1 , wherein a plurality of reinforcing beams are arranged, the base plate structure further comprises a support beam connected between two adjacent reinforcing beams.

12. A vehicle, comprising a battery tray and a battery module, wherein the battery tray is the battery tray of claim 1 , the battery tray is connected to the vehicle, and the battery module is mounted at the battery tray.
