Description

Technical Field

[0001] The utility model relates to the technical field of electric tricycle motors, and in particular to a motor and a drive system integrated with a controller. Background Art

[0002] As the competition in the electric tricycle controller and motor market becomes increasingly fierce, improving product performance and reducing production costs have become the inevitable choice for enterprises to survive and develop. In order to more efficiently exert the performance of motors and controllers, reduce production costs, and more conveniently install the motors and controllers of electric tricycles, it is necessary to improve the installation method of motors, controllers and differentials.

[0003] The commonly used connection method between the controller and the motor is to set the controller at the seat of the electric tricycle and the motor at the half-axle of the vehicle body. Therefore, a longer connecting line is needed to connect the controller and the motor, so as to transmit the operating instructions of the controller to the motor. Since the operating environment of electric vehicles or electric tricycles is almost always outdoors, they will face different weather and terrain environments, which will cause the controller and the motor to be exposed to different temperature, dust, and humidity conditions for operation, so that the connecting line between the controller and the motor will age and break quickly, resulting in unexpected electric vehicle failures.

[0004] In addition, since the controller, motor and differential are produced separately, additional separate packaging is required during the transportation process, as well as a variety of different assembly jigs and operating tools. This results in relatively low production efficiency and requires suppliers and vehicle manufacturers to spend more on packaging materials, equipment and personnel costs. Utility Model Content

[0039] A plurality of strip-shaped reinforcing ribs 8 are arranged on the outer side surface of the bottom end surface 3 .

[0043] The notches 9 are arranged in an arc shape, evenly spaced and circumferentially at the edge of the bottom end surface 3 , and the reinforcing columns 10 can reinforce the bottom end surface 3 where the notches 9 are located.

[0044] The side wall 4 is configured to be barrel-shaped with openings at both ends. The bottom end of the side wall 4 is fixedly connected to the bottom end surface 3 of the controller, and is preferably configured to be integrally formed.

[0045] The outer diameter of the side wall 4 is smaller than the outer diameter of the bottom end surface 3 .

[0046] First connecting members 11 are evenly spaced and arranged circumferentially on the outside of the side wall 4 .

[0047] The first connecting member 11 is preferably formed integrally with the side wall 4. The first connecting member 11 is arranged to fit the notch 9 of the bottom end surface 3, with its upper end surface flush with the upper end surface of the side wall 4, and its lower end surface flush with the surface of the strip reinforcement rib 8.
