Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle frames, in particular to a balanced frame structure for electric vehicles. Background Art

[0002] In the prior art, electric tricycles are common means of transportation. The frames of existing electric tricycles are mainly composed of steel structures. However, in order to ensure that the existing frames have sufficient strength, a center beam is usually passed through the middle of the chassis, so that the batteries of the electric tricycles can only be arranged above the frame, which increases the center of gravity of the electric tricycle and reduces the stability of the vehicle. Moreover, the carriages of existing electric tricycles are mainly arranged on the frame, and the reduced battery arrangement space leads to a reduction in the battery capacity, which is not conducive to improving the performance of the vehicle. In addition, the frames of existing tricycles are fixedly installed when installed with the cargo box. Such an installation method is not convenient for disassembly, assembly and adjustment of the frame and the cargo box. When a part of the frame is damaged, it is not convenient to disassemble and maintain it, which will cause the frame and the cargo box to be scrapped as a whole, and the economic benefits are poor.

[0003] The Chinese utility model patent with application number: 202120856653.5 discloses an electric tricycle frame with a balancing function, including a frame main beam, a load-bearing beam, a load-bearing plate, a cargo box mounting plate, a shock-absorbing rod, a movable block, a sliding rod, a compression spring and a slide groove. The top of the load-bearing beam and the bottom of the cargo box mounting plate are respectively provided with mutually matching horizontal positioning square openings and horizontal positioning square rings. The horizontal positioning rings are matched in the horizontal positioning openings to maintain the level of the cargo box mounting plate. However, the frame structure of this electric tricycle with a balancing function is too simple, and it is not convenient to disassemble and adjust the frame and the cargo box. When a part of the frame is damaged, it is not convenient to disassemble and maintain it, which will cause the frame and the cargo box to be scrapped as a whole, and the economic benefits are poor.
