[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] Refer to the attached Figure 1-4 An electric vehicle frame includes a main beam tube 1, side support tubes 2, and a box body 4, which together form a frame capable of accommodating a battery. The side support tubes 2 are further provided with cross beams 3, and a plurality of side connecting plates 6 are connected between the side support tubes 2 and the cross beams 3. By providing the cross beams 3 and the side connecting plates 6 on the side support tubes 2, and providing the bent connecting plates 8 on the support portions 5, the overall rigidity and impact resistance of the frame are significantly improved. This design can disperse the impact force when the vehicle collides, reducing direct damage to the battery and the plastic shell. The side support tubes 2 are connected to support portions 5 extending toward the main beam tube 1. The bent connecting plates 8 connected to the inner side walls of the support portions 5 are used for connection to the plastic shell. By providing the side connecting plates 6 located on the inner walls of the cross beam 3 and the box body 4, and the bent connecting plates 8 on the inner wall of the support portion 5, a concave cavity with the plastic shell is provided, so that the frame slightly protrudes from the plastic shell. Even in the event of a collision, the frame can ensure the integrity of the plastic shell.

[0023] In this embodiment, the bending area of ​​the support portion 5 is opposite to the main beam tube 1, and the support portion 5 remains parallel to the crossbeam 3. This design helps to improve the stability of the vehicle, especially when driving at high speed or turning, which can reduce the shaking of the vehicle and improve driving safety.

[0024] In this embodiment, the side support tubes 2 are located on both sides of the main beam tube 1 and extend toward the rear of the vehicle frame, wherein the middle portion of the side support tubes 2 protrudes downward. The side support tubes 2 are located on both sides of the main beam tube 1 and extend toward the rear of the vehicle frame. This layout allows for rational utilization of the internal space of the vehicle frame, providing sufficient space for batteries and other components, while also providing sufficient protection for the plastic casing.

[0025] In this embodiment, the raised portion of the side support tube 2 is bent toward the inside of the box body 4 , which helps to quickly position and align the side support tube 2 and the box body 4 during installation, thereby reducing the adjustment time during the installation process.

[0026] In this embodiment, the inner wall of the side support tube 2 near the housing 4 is further provided with an inwardly recessed groove to enhance the side support tube 2's bending resistance. This recessed groove increases the cross-sectional moment of inertia of the crossbeam, thereby improving its bending resistance. This design helps disperse and absorb the impact force during a lateral impact, protecting the battery from damage.

[0027] In this embodiment, a footrest connecting plate 7 and a transverse connecting plate 9 are further connected between the two cross beams 3 .

[0028] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.
