[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] like Figure 1 and Figure 2 As shown, a high-strength electric vehicle frame includes a battery compartment 1, a protective shell 2 is provided on the outside of the battery compartment 1, connecting plates 24 are fixedly connected on both sides of the opening of the protective shell 2, a frame 12 is fixedly connected to the outside of the protective shell 2 through a mounting plate 11 corresponding to the connecting plate 24, a supporting frame 21 is provided inside the protective shell 2 and is arranged on the bottom side of the battery compartment 1, a protective base 22 corresponding to the supporting frame 21 is provided on the outside of the protective shell 2, and a buffer layer 23 is provided inside the protective base 22 and is arranged on the bottom side of the protective shell 2.

[0026] In this embodiment, a protective shell 2 is provided to be sleeved on the outside of the battery compartment 1, and the bottom side of the battery compartment 1 is reinforced with the help of a protective base 11 to prevent the bottom side from being damaged by collision and abrasion. A support frame 21 inside the protective shell 2 is used to prevent the bottom side of the protective shell 2 from being deformed due to collision and squeezing the battery compartment 1.

[0027] like Figure 3 and Figure 4 As shown, the cross section of the support frame 21 is L-shaped, and the battery compartment 1 is installed on the inner side of the support frame 21, so that the outer side of the support frame 21 is close to the inner plate of the protective shell 2. An X-shaped fixing rod 25 is also fixed inside the support frame 21. Corresponding mounting holes 13 are provided on the connecting plate 24 and the mounting plate 11, as well as between the protective shell 2 and the support frame 21, and between the protective shell 2 and the protective base 22, and bolt structures are provided in these mounting holes 13. The frame 12 is composed of a base material layer 14, a protective layer 15 and a protective coating 16 in sequence, and a front end anti-collision rod 17 is also fixed on the front side of the protective base 22.

[0028] In this embodiment, during installation, the support frame 21 is first placed into the protective shell 2, and then the battery compartment 1 is placed on the support frame 21, aligned with the mounting plate 11 and the connecting plate 24, and fixed with a bolt structure; the buffer layer 23 is implanted in the protective base 22, and the support frame 21 and the protective base 22 are fixed to the protective shell 2 with the help of the mounting holes 13.

[0029] When in use, place the support frame 21 inside the protective shell 2, ensuring that the cross-sectional shape of the support frame is correctly placed in the L shape to increase the stability of the structure; place the battery compartment 1 on the support frame 21 that has been placed in the protective shell. In this step, the battery compartment should be tightly fitted with the support frame; align the mounting plate 11 and the connecting plate 24 with the corresponding mounting holes 13 on the protective shell 2. These mounting holes are correspondingly set on the connecting plate, the mounting plate, the protective shell, the support frame and the protective base; use the bolt structure to fix the mounting plate 11 and the connecting plate 24 through the mounting holes 13 to ensure that the protective shell 2, the support frame 21 and the battery compartment 1 are tightly connected together; implant the buffer layer 23 into the inside of the protective base 22 to increase the buffering and protection of the bottom to prevent the battery compartment from being damaged by the bottom impact, fix the protective base 22 and the support frame 21 on the protective shell 2, ensure that all contact surfaces are tightly fitted, and finally fix them through the bolt structure to ensure overall stability; set the frame 12 on the outside of the protective shell 2 and fix the frame through the mounting holes 13. The frame includes a base material layer 14, a protective layer 15 and a protective coating 16, which increase the strength and durability of the overall structure. At the same time, a front end anti-collision rod 17 is fixedly connected to the front side of the protective base to increase the anti-impact capability of the front end of the electric vehicle.

[0030] To summarize the above steps, it can be summarized as first placing the main load-bearing components (support frame, battery compartment) into a protective shell, fixing them with bolts, then adding a buffer layer and a base for protection and buffering, and finally installing the overall frame and anti-collision bar to complete the assembly of the electric vehicle frame, ensuring that the overall strength and protection performance of the battery compartment and frame are effectively improved.

[0031] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
