Description

Technical Field

[0001] This utility model relates to the field of electric vehicle frame technology, and in particular to a high-strength electric vehicle frame. Background Technology

[0002] With the rapid development of electric transportation, electric vehicles have become an important choice for daily travel due to their convenience and environmental friendliness. As the core load-bearing component of an electric vehicle, the performance of the frame directly affects the vehicle's safety, stability, and riding comfort. However, traditional electric vehicle frames have many limitations in design and structure. Firstly, each component has a single function, which not only increases assembly processes and time costs but may also affect the overall vehicle performance due to poor matching between components. Secondly, some key frame components, such as the footrest bracket and seat locking plate bracket, have limited strength and cannot withstand significant pressure and long-term wear. Thirdly, the unreasonable design of the handlebar installation structure makes it easy for welds to tear when lifted upwards, shortening the frame's lifespan. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a high-strength electric vehicle frame. A stable frame is built by the main beam and the sub-beam. The head tube connects the front fork and the main beam and is equipped with a two-in-one combination bracket (corner limit bracket and horn bracket) to ensure steering safety and simplify assembly. The double-layer stamped structure of the footrest mounting bracket improves strength and stability. The seat lock plate bracket is a multi-purpose device that stabilizes the seat and installs the controller. The notch of the armrest mounting piece faces the front of the electric vehicle frame and serves as the mounting point for the armrest, making the structure more reasonable and improving strength. It avoids the risk of tearing at the weld when lifting upwards, which is beneficial to improving the frame strength, stability, safety and assembly convenience, and bringing a comfortable experience to the rider.

[0004] This utility model also provides a high-strength electric vehicle frame as described above, comprising: a main beam, with secondary beams fixedly connected to both sides of the main beam, a head tube fixedly connected to the left end of the main beam, a combined bracket fixedly connected to the side surface of the head tube, a footrest mounting bracket fixedly connected to the upper surface of the secondary beam, a mounting plate fixedly connected to the lower surface of the secondary beam, a double-support limiting block fixedly connected to the lower surface of the mounting plate, a battery support strip fixedly connected to the side surface of the secondary beam, a battery support plate fixedly connected to the upper surface of the battery support strip, a seat locking plate bracket fixedly connected to the upper surface of the secondary beam, and an armrest mounting component fixedly connected to the upper surface of the secondary beam, with a notch provided on the left surface of the armrest mounting component. These components improve the frame's strength, stability, safety, and ease of assembly, providing a comfortable riding experience.

[0005] According to the present invention, a high-strength electric vehicle frame is provided, wherein the combined bracket is composed of a corner limiting bracket and a horn bracket combined into one, and is located on the left side of the head tube. The above device is beneficial to improving the practicality and production efficiency of the frame.

[0006] According to the high-strength electric vehicle frame provided by this utility model, the battery support strip and battery support plate are both located below the sub-beam, and the foot mounting bracket adopts a double-layer stamped structure. The above devices are beneficial to enhancing the strength of the components.

[0007] According to the high-strength electric vehicle frame provided by this utility model, the bottom of the mounting plate has a flanged structure, and the battery support strip is fixedly connected to the upper surface of the flanged edge of the mounting plate. The above device helps to ensure the stability of the battery support strip.

[0008] According to the high-strength electric vehicle frame provided by this utility model, the armrest mounting component is located on the right side of the seat cushion lock plate bracket, and the notch faces the left side. The above device helps to avoid the risk of tearing at the weld when lifting upwards.

[0009] Compared to existing technologies, this high-strength electric bicycle frame features a robust framework constructed from a main beam and sub-beam. The head tube connects the fork to the main beam and is equipped with a two-in-one bracket (corner limit bracket and horn bracket), ensuring steering safety and simplifying assembly. The footrest mounting bracket's double-layer stamped structure enhances strength and stability. The seat lock plate bracket serves multiple purposes, stabilizing the seat and mounting the controller. The notch on the handlebar mounting piece faces the front of the electric bicycle frame, serving as the mounting point for the handlebar, making the structure more rational and increasing strength. This avoids the risk of tearing at the weld when lifting upwards, contributing to improved frame strength, stability, safety, and ease of assembly, and providing riders with a comfortable experience.
