Description

Technical Field

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

[0002] In the fields of modern mechanical engineering and transportation vehicle manufacturing, modular design is becoming an important direction for industrial upgrading due to its advantages of efficient production, convenient maintenance, and flexible adaptation. As the core carrier of new energy transportation, the modularity of the electric vehicle's frame structure directly affects the product's manufacturing efficiency, user experience, and total lifecycle cost. Traditional electric vehicle frames, limited by an integral welded structure, while meeting basic load-bearing requirements, are gradually revealing significant technical bottlenecks when facing diverse market demands and a rapidly iterating industry pace.

[0003] In existing technologies, the various functional components of a vehicle frame are typically integrated using fixed connections, resulting in a high degree of physical and functional coupling between modules. This design often requires complete disassembly and reassembly of related components for after-sales maintenance, which not only consumes significant time and costs but also easily causes structural damage due to repeated disassembly. During product iterations, design changes to a single module often require affecting the entire frame structure, severely restricting the personalized development and platform application of vehicle models. Although some technologies attempt to achieve module separation through simple detachable connections, they generally suffer from insufficient reliability of the connection structure and significant degradation of mechanical performance, making it difficult to achieve an effective balance between ease of quick assembly and disassembly and structural strength. Furthermore, traditional vehicle frames lack flexible structural adaptation mechanisms to meet the differentiated load requirements of different vehicle models, resulting in low universality and further increasing mold development and manufacturing costs.

[0021] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figure 1-5 As shown, a modular quick-release electric vehicle frame includes a main body module 1 and a seat cushion module 2, wherein the main body module 1 and the seat cushion module 2 are detachably connected.

[0024] The main module 1 includes a front riser 11 and two side beams 12 fixedly connected to the front riser 11. The side beams 12 include a front connecting section 121, an arc-shaped turning section 122 and a rear connecting section 123.

[0025] The seat cushion module 2 includes two seat cushion support tubes 21 and two first support tubes 22. The seat cushion support tubes 21 are detachably connected to the arc-shaped turning section 122 through a first threaded connection structure 4 that can be quickly disassembled and assembled. One end of the first support tube 22 is fixedly connected to the seat cushion support tube 21, and the other end is detachably connected to the rear connection section 123 of the side beam tube 12 through a second threaded connection structure 5 that can be quickly disassembled and assembled.

[0026] The main module adopts a segmented side beam tube design. The arc-shaped turning section 122 provides a central support fulcrum for the seat cushion module. The front connecting section 121 and the rear connecting section 123 achieve uniform stress distribution through an arc transition, avoiding stress concentration at the welding joint. The seat cushion module, through the detachable connection structure at both ends, ensures installation stability and meets the requirements for quick assembly and disassembly.

[0027] Furthermore, the first threaded connection structure is provided with corresponding first bolt holes on the seat support tube 21 and the arc-shaped transition section 122. The first bolt passes through the first bolt hole and is threaded with a first nut. Through the standard connection of the bolt and nut, the front end of the seat support tube and the arc-shaped transition section are rigidly fixed. The corresponding setting of the bolt holes ensures positioning accuracy, and the detachability of the threaded connection allows the disassembly and assembly process to be completed without special tools, only with a regular wrench, significantly improving the convenience of operation and making it suitable for mass production assembly and after-sales maintenance scenarios.

[0028] Furthermore, the second threaded connection structure 5 includes a guide mounting groove extending through the rear connecting section 123. The other end of the first support tube 22 extends through the guide mounting groove to the end of the rear connecting section 123 near the front riser 11. The guide mounting groove has a mounting hole, and the first support tube 22 has a threaded hole corresponding to the mounting hole. The second bolt passes through the mounting hole and is threadedly connected to the threaded hole. The design of the guide mounting groove provides an insertion guide for the first support tube 22, ensuring that the position is aligned when the rear end is connected, and reducing installation deviation. The cooperation between the mounting hole and the threaded hole forms an "insertion-locking" mechanism, and the second bolt enters from the outside of the side beam tube and connects to the threaded hole inside the support tube.

[0029] Furthermore, the two seat support tubes 21 are fixedly connected by a fourth support tube 23. The fourth support tube 23 forms a lateral reinforcement structure, which together with the two seat support tubes 21 forms a stable frame, effectively resisting lateral deformation and torsional loads in the seat area during riding, improving riding comfort and structural durability, and is especially suitable for maintaining stiffness under heavy load conditions.

[0030] Furthermore, the main module 1 also includes a second support tube 13 and a third support tube 14. The two ends of the second support tube 13 are welded to the rear connecting sections 123 of the two side beam tubes 12, respectively. One end of the third support tube 14 is fixedly connected to the middle of the second support tube 13, and the other end is fixedly connected to the front upright tube 11. The second support tube 13 laterally connects to the rear sections of the two side beam tubes, forming a rear lateral support. The third support tube 14 obliquely connects the front upright tube and the rear lateral support, together with the side beam tubes, forming a triangular support system. This triangular structure utilizes the principle of geometric stability to significantly improve the overall torsional stiffness and longitudinal bending resistance of the frame, effectively dispersing the impact force from the road surface and the motor vibration load during riding, adapting to the high-intensity usage requirements under complex road conditions.

[0031] Furthermore, the front connecting section 121, the arc-shaped turning section 122, and the rear connecting section 123 of the side beam tube 12 are integrally formed structures. The integral forming process avoids the risk of weld defects caused by segmented welding, reduces stress concentration points, and improves the overall strength and fatigue life of the side beam tube; at the same time, it simplifies the processing procedures, improves production efficiency, ensures the consistency of geometric accuracy of each segment, and provides a reliable reference structure for subsequent modular connection.

[0032] Furthermore, the second support tube 13 and the third support tube 14 are connected by welding or by using an integral molding structure.

[0033] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
