[0002] In the prior art, electric tricycles have the advantages of strong applicability, maneuverability, simple maintenance, convenient repair, low price, etc., and can flexibly travel through narrow roads. Electric tricycles have a reversing switch, which can easily realize the reverse and forward driving functions, which is very practical in narrow alleys and lanes.

After long-term bumps, the fixing effect will deteriorate, the stability effect will deteriorate, and after long-term use, it is very easy to cause the chassis bracket to deform, which in turn leads to insufficient strength of the chassis frame and weak stability. In addition, during long-term use, users may have the phenomenon of connectors or welding points falling off, which poses a riding danger.
