Description

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] In the field of electric vehicle manufacturing, the chassis, as the core load-bearing component of the vehicle, directly affects the vehicle's performance and appearance integrity through its assembly structure with the body's plastic parts.

[0003] In the production process of existing electric bicycle frames, one method involves drilling screw holes on adjacent frame tubes and connecting plastic parts to the frame tubes with screws, so that multiple frame tubes form a support inside the plastic parts to form a frame cavity. Alternatively, the plastic parts are placed inside the supporting frame tubes, with the frame tubes supporting the plastic parts. However, both methods inevitably require the placement of plastic parts on the frame tubes during the production of electric bicycle frames. According to the new national standard GB17761-2024, the total mass of plastic used in electric bicycles should not exceed 5.5% of the total vehicle mass. In order to comply with the new national standard, the use of plastic parts on the frame needs to be reduced. This application aims to solve the problem of the use of plastic parts in traditional electric bicycle frames to improve the overall performance and aesthetics of the frame. However, the large number of plastic parts often makes the electric bicycle frame prone to deformation, cracking, and other problems that affect the structural stability of the frame under complex road conditions and harsh environments. Therefore, an electric bicycle frame is proposed. Utility Model Content

[0049] Ideally, the footrest 203 should be key-shaped;

[0050] The footrest 203 can be configured as shown in the attached figure. Figure 3 The key shape shown can also be other shapes, such as a long strip or a square shape. It is generally distributed on the other side of the surface of the middle frame 201. The footrest 203 can be equipped with a footrest or not.

[0051] The footrest 203 is connected to a component assembly 5, which includes a connecting shaft tube 501, a combination frame 502 connected to the outer surface of the connecting shaft tube 501, two fixing bars 503 connected to the combination frame 502, a combination tube 504 connected between the two fixing bars 503, a connecting piece 505 connected to one end of the fixing bar 503, a connecting rod 506 connected to the lower end of the connecting shaft tube 501, a combination piece 507 connected to the connecting rod 506, and a connecting rod 508 connected to the combination piece 507.

[0058] Example 2:

[0059] Based on the above embodiment 1, in order to solve the problem that the integral cutting of the frame panels will generate a large amount of waste sheet metal, refer to Figure 6 The structure shown is...

[0060] Unlike Embodiment 1, the fixed connection also includes welding the tail end of the front frame 101 to the head end of the middle frame 201, and welding the tail end of the middle frame 201 to the head end of the rear frame 301.

[0061] The front frame 101, middle frame 201, and rear frame 301 are connected by laser welding. This allows for the arrangement of the front frame 101, middle frame 201, and rear frame 301 during the blanking process of the frame assembly. This results in less waste material from punching the entire electric vehicle frame, thereby significantly reducing the overall production cost of the electric vehicle frame. When laser welding is used to fix them together as one piece, the thickness of the middle frame 201 can be less than the thickness of the rear frame 301 and the front frame 101. By reducing the thickness of the middle frame 201, the weight can be reduced, thus saving raw materials and lowering costs.

[0062] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
