DETAILED DESCRIPTION

[0027] The utility model will now be further described in detail with reference to the accompanying drawings.

[0028] See also Figure 1-4 As shown, in this embodiment, a lightweight chassis for a new energy vehicle is provided, including a chassis body structure 1, a battery compartment 2 is arranged in the middle of the chassis body structure 1, slide holes 3 are opened on both sides of the inner wall of the battery compartment 2, a telescopic rod structure 4 is inserted in the inner cavity of the slide hole 3, the telescopic rod structure 4 is located at one end of the inner cavity of the battery compartment 2 and a clamping plate structure 5 is fixedly installed, and a clamping spring 6 is mounted on the outer ring of the telescopic rod structure 4 located between the clamping plate structure 5 and the inner wall of the battery compartment 2.

[0029] A cover plate structure 7 is installed on the top of the battery compartment 2 , a positioning hole 8 is provided at the bottom of the cover plate structure 7 and just above the slideway hole 3 , and breakaway pieces 9 are fixedly connected to both ends of the bottom of the cover plate structure 7 .

[0030] Among them, the slide hole 3 is an arc-shaped hole, the telescopic rod structure 4 is an arc-shaped rod structure, and the outer wall of the telescopic rod structure 4 is in compression contact with the inner wall of the slide hole 3, and the two slide and rub, which can serve as a damping structure of the clamping spring 6.

[0031] The collapse pieces 9 are elastic pieces, and two collapse pieces 9 form a group. Each group of collapse pieces 9 is located on both sides of the side of the clamping plate structure 5. After the cover plate structure 7 is installed, the side of the collapse piece 9 is squeezed and contacted with the side of the clamping plate structure 5.

[0032] Among them, the clamping plate structure 5 adopts a hollow plate structure design. The overall weight of the hollow clamping plate structure 5, the clamping spring 6 and the telescopic rod structure 4 is light compared to the existing alloy fasteners. In addition, combined with the design of the longer slide hole 3, the weight dug out of the chassis is compared to the length of the threaded hole in the prior art, which further reduces the weight of the entire chassis.

[0033] In this embodiment, Figure 1-4 As shown, based on the existing new energy vehicle chassis, when installing the battery pack, one end of the battery pack is directly squeezed onto the side of the clamping structure 5 on one side until it reaches the limit position, and then the clamping structure 5 on the other side is operated to allow the clamping structure 5 to move close to the inner wall of the battery compartment 2. During the movement of the clamping structure 5, the clamping spring 6 is compressed, and the top of the telescopic rod structure 4 passes through the slide hole 3 and extends a distance. After reaching the limit position, the other end of the battery pack is placed in the battery compartment 2, and finally the cover structure 7 is covered at the top position of the battery compartment 2. When installing the cover structure 7, each positioning hole 8 corresponds to the extended telescopic rod structure 4 one by one, and the collapse piece 9 is inserted into the space between the clamping structure 5 and the inner wall of the battery compartment 2, and the collapse piece 9 is affected by the reverse force and is in a deformed state, that is, the collapse piece 9 is bent toward the inner wall of the battery compartment 2, and there is an interaction between the clamping structure 5 and the clamping structure 5.

[0034] Therefore, the above technical solution can realize an installation method without a fastener structure. After the chassis and the battery pack are installed, compared with the prior art that uses many fasteners to achieve installation and fixation, it obviously has the effect of reducing the weight of the chassis.

Combined with the glue of the battery pack, a fastener-free installation method of the battery pack can be realized. While reducing the weight of the vehicle chassis, the battery pack can also be quickly installed.
