Technical Field

[0001] This utility model relates to the field of electric vehicle accessories, and in particular to an electric vehicle frame. Background Technology

[0002] Existing electric vehicle brackets are mostly formed by welding metal parts, resulting in numerous weld points. This not only affects the overall aesthetics of the vehicle body but also carries the risk of weld failure at each weld point. In addition, the irregularity of the existing frame structure makes the installation and production of frame attachments difficult. It requires consideration of how to design and install based on the frame structure, making it difficult to create a universal frame that can be used for the production of multiple electric vehicle models. Summary of the Invention

[0003] The purpose of this utility model is to solve the above-mentioned problems by designing an electric vehicle frame. The specific design scheme is as follows: An electric vehicle frame includes a base frame, which is an integral structure formed by bending a metal tube. The base frame is provided with reinforcing tubes for increasing the strength of the frame and attachments for connecting other components of the electric vehicle. The attachments include a head tube, a battery box mounting bracket, a seat bracket, and a rear rack.

[0004] Before bending, the base frame is a rectangular frame structure. The long side of the rectangular frame structure is bent and together with the short side of the rectangular frame structure forms the base frame. The reinforcing tube connects the two opposite long sides of the rectangular frame structure.

[0005] The front part of the base frame is bent clockwise to form a first bending section. After the first bending section is bent, the front part of the electric vehicle and the front part of the vehicle body are formed. The clockwise bending is formed when the rectangular frame structure of the base frame is placed horizontally, so that the long side is rotated clockwise downward at the first bending section.

[0006] The middle part of the base frame is bent counterclockwise to form a second bending section. After the second bending section is bent, it forms the bottom of the electric vehicle body. The second bending section connects the front part of the vehicle body and the bottom part of the vehicle body. The counterclockwise bending is a bend formed by rotating the long side of the rectangular frame structure of the base frame downward counterclockwise at the second bending section when the rectangular frame structure is placed horizontally.

[0007] The middle and rear part of the base frame rotates counterclockwise to form a third bending section. After bending, the third bending section forms the rear part of the vehicle body, and the third bending section connects the rear part of the vehicle body to the bottom of the vehicle body.

[0008] The rear part of the base frame rotates counterclockwise to form a fourth bend, and the fourth bend forms the rear of the vehicle body. The fourth bend connects the rear of the vehicle body to the rear of the vehicle body.

[0009] A head tube is provided at the first bend, and the head tube is connected to the base frame through a reinforcing tube. The head tube is used to install and connect the front plug and handlebars.

[0010] A battery box mounting bracket is provided at the third bend section. The two ends of the battery box mounting bracket are directly connected to the two long sides of the rectangular frame structure. The battery box mounting bracket is used to fix and connect the battery box.

[0011] A seat support is provided at the fourth bend section. The two ends of the seat support are directly connected to the two long sides of the rectangular frame structure. The seat support is used to install the seat. A rear coat rack is provided at the rear end of the seat support.

[0012] The electric vehicle frame obtained by the above-described technical solution of this utility model has the following beneficial effects: The lightweight design of the frame structure reduces the weight of the electric vehicle. The lining beams not only increase the structural strength of the frame, but also allow the frame to be adapted to the production of various electric vehicle models by considering the different bending angles and positions of the various bending sections of the frame, based on the installation requirements of the vehicle attachments and their corresponding positions on the frame.

Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings.

[0015] An electric vehicle frame includes a base frame 1, which is an integral structure formed by bending a metal tube. The base frame 1 is provided with a reinforcing tube 2 for increasing the strength of the frame and attachments for connecting other components of the electric vehicle. The attachments include a head tube 12, a battery box mounting bracket 13, a seat bucket bracket 14, and a rear rack 15.

[0016] Before bending, the base frame 1 is a rectangular frame structure. The long side of the rectangular frame structure is bent and together with the short side of the rectangular frame structure forms the base frame 1. The reinforcing tube connects the two opposite long sides of the rectangular frame structure.

[0017] The front part of the base frame 1 is bent clockwise to form a first bending section 3. After the first bending section 3 is bent, the front part 4 and the front part 5 of the electric vehicle are formed. The clockwise bending is the bending formed when the rectangular frame structure of the base frame 1 is placed horizontally, so that the long side is rotated downward clockwise at the first bending section 3.

[0018] The middle part of the base frame 1 is bent counterclockwise to form a second bending segment 6. After the second bending segment 6 is bent, it forms the bottom of the electric vehicle body 7. The second bending segment 6 connects the front part 5 of the vehicle body and the bottom part 7 of the vehicle body. The counterclockwise bending is a bend formed by the long side of the rectangular frame structure of the base frame 1 rotating counterclockwise downward at the second bending segment 6 when the rectangular frame structure of the base frame 1 is placed in the horizontal direction.

[0019] The middle and rear part of the base frame 1 rotates counterclockwise to form a third bending section 8. After bending, the third bending section 8 forms the rear part of the vehicle body 9. The third bending section 8 connects the rear part of the vehicle body 9 and the bottom part of the vehicle body 7.

[0020] The rear part of the base frame 1 rotates counterclockwise to form a fourth bending section 10. The fourth bending section 10 bends to form the rear part of the vehicle body 11. The fourth bending section 10 connects the rear part of the vehicle body 9 and the rear part of the vehicle body 11.

[0021] A head tube 12 is provided at the first bend section 3. The head tube 12 is connected to the base frame 1 through a reinforcing tube 2. The head tube 12 is used to install and connect the front plug and handlebars.

[0022] A battery box mounting bracket 13 is provided at the third bending section 8. The two ends of the battery box mounting bracket 13 are directly connected to the two long sides of the rectangular frame structure. The battery box mounting bracket 13 is used to fix and connect the battery box.

[0023] A seat support 14 is provided at the fourth bend section 10. The two ends of the seat support 14 are directly connected to the two long sides of the rectangular frame structure. The seat support 14 is used to install the seat. A rear coat rack 15 is provided at the rear end of the seat support 14.

[0024] During production, only a rectangular frame-shaped base frame blank 1 needs to be produced in a standardized manner. Then, it is bent into the shape of the base frame according to the bending section. Then, reinforcing tubes and attachments are welded onto the base frame 1. The strength of the frame can be increased by increasing the number of reinforcing tubes 2. The position of the reinforcing tubes 2 can be changed to adapt to the installation of attachments for different models, thereby reducing the overall production and design cost of electric vehicles. The one-piece molded base frame 1 has no welding points, and the structure can be adapted to the production needs of different electric vehicle models by changing the position of the bending section.

[0025] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
