Description

Technical Field

[0001] The utility model relates to the field of tricycle frames, in particular to a frame with increased load-bearing capacity. Background Art

[0002] In the prior art, the frame of an electric tricycle is mainly composed of several vehicle brackets welded to the main frame beam, and welded to a seat rod, an auxiliary frame beam, a front longitudinal frame beam, a main shaft mounting seat and a front wheel mounting seat. The rear wheel mounting seat is installed under the vehicle bracket, and the battery is welded to the bottom of the connection between the vehicle bracket and the main frame beam. When an electric tricycle frame with this structure is equipped with left and right rear wheels, the force-bearing area is small and the strength is low. When an accident occurs or when a large amount of load is borne, the connection strength between the rear of the tricycle and the cab is low, which often easily leads to wear at the connection and further reduction in strength. Therefore, it is necessary to provide a frame that can improve the connection strength and stability between the tricycle frame and the cab. Utility Model Content

[0010] The beneficial effects are: the first longitudinal beam and the second longitudinal beam are supported by the support rod, so that the load-bearing capacity of the frame is improved, and the connection strength between the frame and the cab is improved.

[0011] Preferably, as an improvement, at least two third longitudinal beams are further included, and both ends of the third longitudinal beams are respectively welded and fixedly connected to the cross beam.
