Description

Technical Field

[0001] The utility model belongs to the technical field of joint motor structures, and in particular relates to a wire harness fixing structure used in a joint motor. Background Art

[0002] The joint motor is a mechatronic device consisting of a motor and a reducer. Its working principle is based on the synergy of the motor and the reducer to achieve high-precision movement. The joint motor is mainly composed of the motor body, reducer, bearing, controller component, shell and other parts. Among them, the motor body is the core part of the joint motor, responsible for generating rotational power; the reducer reduces the rotation speed of the motor to a speed suitable for the joint motor to work; the controller component is used to detect information such as the motor speed and the speed of the reducer output end, and accurately control the motor; the bearing is used to support the rotating part of the motor; and the shell protects the various parts of the joint motor from damage by the external environment.

[0003] In order to ensure high-precision position control of the joint motor, it is generally necessary to perform corresponding detection on the position and speed of the output wheel at the output end of the reducer. The reducer and controller components are usually arranged at both ends of the motor and are far apart. Therefore, the detection sensor at the output wheel is generally connected to the controller component through a wiring harness. At the same time, since the output wheel at the output end of the reducer will rotate, and the controller component is usually fixed to the shell and remains stationary, the above-mentioned connecting wiring harness is prone to entanglement, and in severe cases it may even cause the wiring harness to break, and the connection between the wiring harness and the controller component may also become loose, affecting the normal use of the joint motor.
