[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0018] Please refer to Figure 1A new multifunctional motor and gearbox connecting conversion sleeve can include a connecting sleeve 2. The connecting sleeve 2 can be in the form of a circular tube with a through cavity, and a spline groove is formed on the inner wall of both ends of the connecting sleeve 2. According to the spline specifications of the motor output shaft 1 and the gearbox input shaft 3 of the electric tricycle on the market, the connecting sleeve 2 can have multiple groups of different combinations of models. During installation, one end of the connecting sleeve 2 can be sleeved on the motor output shaft 1, and the other end of the connecting sleeve 2 can be sleeved on the gearbox input shaft 3, and the spline grooves at both ends of the connecting sleeve 2 can be adapted to the splines formed on the outer walls of the motor output shaft 1 and the gearbox input shaft 3, respectively, so that the two ends of the connecting sleeve 2 are clamped and fixed between the motor output shaft 1 and the gearbox input shaft 3 to complete the connection. When the motor output shaft 1 rotates, the connecting sleeve 2 can transmit the rotating action to the gearbox input shaft 3, so that both of them move at the same time.
