Description

Modularized quick-release electric vehicle frame Technical Field The utility model relates to the technical field of frames, in particular to a modularized quick-release electric vehicle frame. Background In the field of modern mechanical engineering and vehicle manufacturing, the modular design concept is becoming an important direction of industry upgrading due to the advantages of efficient production, convenient maintenance and flexible adaptation. The electric vehicle is used as a core carrier of new energy traffic, and the modularization degree of a frame structure of the electric vehicle directly influences the manufacturing efficiency, the use experience and the full life cycle cost of a product. The traditional electric vehicle frame is limited by an integral welding framework, and can meet basic bearing requirements, but when coping with diversified market requirements and rapid iterative industrial rhythms, a remarkable technical bottleneck is gradually exposed. In the prior art, all functional components of the frame are usually integrated in a fixed connection mode, so that the physical and functional coupling degree between modules is high. When the design is subjected to after-sales maintenance, the related components are required to be integrally disassembled, so that a large amount of time and cost are consumed, structural damage is easily caused by repeated disassembly, and in the product iteration process, the whole frame structure is required to be pulled by design change of a single module, so that personalized development and platform application of the vehicle type are severely restricted. Although some technologies attempt to realize module splitting through simple detachable connection, the problems of insufficient reliability of a connection structure, obvious attenuation of mechanical properties and the like generally exist, and effective balance between the convenience of quick assembly and disassembly and the structural strength is difficult to achieve. In addition, when the traditional frame is used for coping with the different load demands of different vehicle types, a flexible structure adaptation mechanism is lacked, so that the universalization degree is low, and the mold development and production manufacturing cost is further increased. Disclosure of utility model The utility model aims to provide a modularized quick-release electric vehicle frame.
