DETAILED DESCRIPTION

[0019] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0020] like Figure 1 As shown, the output shaft of the motor 1 is connected to the reducer assembly 5 to reduce the output torque and increase the torque. The power is output through the output shaft 4 of the reducer assembly 5. The potentiometer 3 is connected to the reducer assembly 5 to detect the rotation angle in real time.

[0021] like Figure 2 As shown, the motor 1 includes a motor 1, a synchronizer, a motor 2, and a brake 103 connected to the motor shaft 2 104. In order to improve the coaxiality and position of the transmission shaft of the motor 1, the housing 110 is processed in an integrated manner, the motor shaft 101 and the stator 111 are installed in the housing 110, and the rear end cover 109 is rotatably matched with the motor shaft 101 through a bearing. The stator 2 105 and the motor shaft 2 104 are both installed in the housing 110, and the end face of the front end cover 2 106 is rotatably matched with the motor shaft 2 104 through a bearing.

[0022] like Figure 3 As shown, the fork rod 107, the fork ring 112, and the synchronizer slider 102 form a synchronizer, the housing 110 and the rear end cover 109 are processed with rectangular holes, the fork rod 107 passes through the rectangular hole and is connected with the fork ring 112, and the fork ring 112 is rotatably matched with the synchronizer slider 102. The upper part of the fork ring 112 is processed with a square hole, and the fork rod 107 can be placed in the square hole for connection.

[0023] Furthermore, a circular hole is processed on the upper end of the fork rod 107, and the output shaft of the linear motor 2 passes through the circular hole and is fixed by the fork locking nut 108. The freedom of one end of the output shaft of the linear motor 2 and the freedom of the other end are constrained by the stepped shaft on the output shaft of the linear motor 2.

[0024] Furthermore, the linear motor 2 is fixedly connected to the housing 110. The inner hole of the synchronizer slider 102 is processed with a spline, and the rear end of the motor shaft 101 and the front end of the motor shaft 2 104 are both processed with splines.

[0025] Specifically, the fork ring 112 is a semicircular ring structure, and the contact surface with the synchronizer slider 102 is copper-plated to reduce the friction of the contact surface during the rotation of the motor 1. In addition, the inner hole diameter of the fork ring 112 is larger than the diameter of the fork ring groove in the synchronizer slider 112. During operation, the fork ring groove in the synchronizer slider 112 does not contact the inner hole of the fork ring 112, and the contact surface is only two end faces.

[0026] During operation, for small torque output, the controller controls the linear motor 2 to push the synchronizer to slide in the direction of the motor 2, and only the motor 1 outputs power during operation. When the rotation fixed position needs to be locked, the brake 103 is in a power-off locking state, and the linear motor 2 is controlled to push the synchronizer to slide in one motor position, so that the motor shaft 101 is connected to the motor shaft 2 104 for self-locking. For large torque output, the motor shaft 1 101 and the motor shaft 2 104 are connected through the synchronizer, and the controller is used to control the motor 1 and the motor 2 to be powered at the same time for large torque output. In high-reliability application places, when the motor 1 fails, the controller controls the linear motor 2 to push the synchronizer to connect the motor shaft 1 101 and the motor shaft 2 104, and energize the motor 2, so that the electric mechanism can still work normally.

[0027] In summary, when running under small load, only one motor needs to be controlled to run. When the position needs to be self-locked, the two motor shafts can be connected in series by controlling the synchronizer. The end motor has a brake to lock the output position. In case of emergencies, large load output is required. The synchronizer is controlled by the controller to move and connect the two motor shafts, and the two motors are powered at the same time for large load output. When running under small load, when motor one fails, the synchronizer is controlled by the controller to connect motor shaft one and motor shaft two, and motor two is powered on, and the operation can continue, which improves the reliability of the electric mechanism. At the same time, motor one, motor two, and synchronizer all use one housing, which improves the coaxiality and position of the two motor shafts.
