Mounting and fixing device for electric tricycle motor

Abstract

The invention discloses a mounting and fixing device for an electric tricycle motor, and the device comprises a mounting seat, a motor fixing assembly, a rear axle connecting assembly, a gearbox connecting assembly and a frame connecting assembly which is arranged on the mounting seat and is used for fixing the whole mounting seat on a frame. The motor fixing assembly comprises a shell sleeving the motor, a front end cover installed at one end of the shell and used for clamping the fixed end of the motor, a rear end cover installed at the other end of the shell and used for clamping the output end of the motor, a cooling fan installed on the side, away from the shell, of the front end cover, and a dustproof air inlet cover installed on the side, away from the front end cover, of the cooling fan. A refrigeration assembly capable of cooling the motor is installed in the shell, and heat dissipation holes are formed in the rear end cover. According to the invention, the motor can be installed and fixed, the connection stability among the motor, the gearbox and the rear axle is improved, and the situation of loosening of the motor is reduced; the heat dissipation effect of the motor is improved, and damage to the motor in the driving process is reduced.

Description

technical field [0001] The invention relates to a mounting and fixing device for an electric tricycle motor, belonging to the technical field of motors. Background technique [0002] The electric tricycle is to drive the motor with electric power, and the tricycle driven by the motor and the transmission mechanism to rotate the wheels has been widely used in people's daily life. At present, the motors of electric tricycles are mostly directly fixed and installed at the bottom of the compartment, and their input terminals are connected to the controller to receive control signals; the output terminals are connected to the rear axle of the electric tricycle through the gearbox to drive the entire vehicle body forward. During use, there are the following problems: [0003] 1. Since the motor is only fixed to the gearbox, rear axle and the entire electric vehicle through the output end, except for the connection point of the output end, it is basically in a suspended state.

AI Technical Summary

Problems solved by technology

[0003] 1. Since the motor is only fixed to the gearbox, rear axle and the entire electric vehicle through the output end, except for the connection point of the output end, it is basically in a suspended state. When the electric tricycle walks on a bumpy road for a long time, it is easy to cause the motor to loosen. The situation causes problems in the walking of the entire electric tricycle, which leads to risks such as car accidents;

[0004] 2. The existing motors are basically directly exposed, and the bottom of the electric tricycle will raise a lot of dust during driving, and the dust is easy to accumulate on the surface of the motor, affecting the heat dissipation effect of the motor; Objects will also hit the motor, causing damage to the motor and affecting the service life of the motor;

[0005] 3. Existing motors basically use fans to dissipate heat or natural heat dissipation. Under extreme working conditions or high temperature weather, driving for a long time will cause the motor to fail to convert all electrical energy into kinetic energy, and part of the electrical energy will be converted into heat energy. The temperature of the motor is increased, and the existing heat dissipation method cannot dissipate the heat in time, causing the motor to be easily short-circuited and burned out due to excessive temperature, reducing the service life of the motor
