[0002] Generally, electric motors need electricity to drive devices. When there is a power outage or power failure, the devices cannot be operated urgently. For example, electric doors usually drive loads that require motor drive, and when there is a power failure, the loads need to be moved urgently, which often causes huge losses and injuries to machines or personnel. Therefore, a motor with manual and electric clutch devices is provided. In the event of an emergency power failure, the device can be operated manually by pulling ropes, chains, etc. to avoid disasters. In addition, the existing solutions basically rely on friction, the output torque of the mechanism is small, and there is no self-locking force. Once the user lets go, the load will quickly return to normal, which is very dangerous. Summary of the invention

[0003] The purpose of the present invention is to overcome the problem in the prior art that the motor cannot be operated urgently when the power is off or outage, and to provide a motor with manual and electric clutch devices. When used manually, less physical effort can be spent to move heavy loads, and it has a certain self-locking property and is relatively safer.

[0004] The object of the present invention can be achieved by the following technical scheme: an electric motor with manual and electric clutch devices, comprising a motor body, wherein a motor output shaft and a clutch are arranged in the motor body, wherein the clutch is mounted on the motor output shaft, wherein a reduction mechanism mounted on the clutch is also arranged in the motor body, wherein the reduction mechanism is composed of a worm wheel and a worm, wherein the worm wheel is mounted on the clutch, wherein the worm wheel is connected to the worm, and wherein one end of the worm extends out of the motor body; wherein the clutch comprises a cam ring, an axial clutch rod, a clutch sleeve and an output sleeve, wherein the output sleeve and the axial clutch rod are arranged in a manner similar to the embodiment of the present invention. The axial clutch rod is sleeved on the output shaft of the motor, a cam ring is installed on the end of the axial clutch rod away from the output sleeve, a clutch sleeve and a worm gear are sleeved on the axial clutch rod, the output sleeve, the clutch sleeve and the worm gear are arranged in sequence, a plurality of round holes are opened on the output sleeve, the clutch sleeve and the worm gear are connected by a plurality of round pins, the round pins of the clutch sleeve and the worm gear correspond to and match with the round holes of the output sleeve; a manual device and a rope-controlled clutch switch are arranged outside the motor body, the manual device is connected to one end of the worm, and the rope-controlled clutch switch extends into the motor body and is connected to the cam ring.

[0005] Furthermore, the manual device includes a manual wheel and a pull rope or chain installed on the manual wheel.

[0006] Furthermore, an axial protrusion is formed on the cam ring.

[0007] Compared with the prior art, the advantages of the present invention are: the motor is switched between electric mode and manual mode through a rope-controlled clutch switch. It is usually in electric mode, and when there is a power outage or power failure, it is switched to manual mode. The power source of the motor output shaft is switched to a manual device through the clutch, and the motor is operated by pulling a rope or a chain, and the purpose of manual labor saving can be achieved in combination with a reduction mechanism. This motor can be applied to situations where a load that needs to be driven by a motor needs to be moved urgently when the power is off, such as the gates of factories and enterprises. Moreover, the reduction mechanism in the present invention allows the operator to move a heavy load with less physical effort when using the motor. The reduction mechanism has a certain self-locking property and is relatively safer. In summary, the present invention has the characteristics of saving manpower, large output torque, self-locking, and greater safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the present invention. Although the present invention is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the present invention.

[0029] like Figures 1 to 5 As shown, the motor with manual and electric clutch devices includes a motor body 1, wherein the motor body 1 is provided with a motor output shaft 5 and a clutch 3, wherein the clutch 3 is mounted on the motor output shaft 5, wherein the motor body 1 is further provided with a reduction mechanism mounted on the clutch 3, wherein the reduction mechanism is composed of a worm wheel 11 and a worm 10, wherein the worm wheel 11 is mounted on the clutch 3, wherein the worm wheel 11 is connected to the worm 10, wherein one end of the worm 10 extends to the outside of the motor body 1; wherein the clutch 3 includes a cam ring 6, an axial clutch rod 7, a clutch sleeve 8 and an output sleeve 9, wherein the output sleeve 9 and the axial clutch rod 7 are sequentially sleeved on the motor output shaft 5, wherein the axial clutch rod 7 moves along the axial direction of the motor output shaft 5, and wherein the axial clutch rod A cam ring 6 is installed on the end of 7 away from the output sleeve 9, and a clutch sleeve 8 and a worm wheel 11 are mounted on the axial clutch rod 7. The output sleeve 9, the clutch sleeve 8, and the worm wheel 11 are arranged in sequence. A plurality of circular holes 9a are opened on the output sleeve 9. The clutch sleeve 8 and the worm wheel 11 are connected by a plurality of round pins 8a. The round pins 8a of the clutch sleeve 8 and the worm wheel 11 correspond to and match the circular holes 9a of the output sleeve 9; a manual device 2 and a rope-controlled clutch switch 4 are provided outside the motor body 1. The manual device 2 is connected to one end of the worm 10, and the rope-controlled clutch switch 4 extends into the motor body 1 and is connected to the cam ring 6. The rope-controlled clutch switch 4 includes a pull rope, which extends into the motor body 1 and is connected to the cam ring 6.

[0030] In a specific implementation, the manual device 2 includes a manual wheel and a pull rope or chain installed on the manual wheel, and the manual wheel is installed at one end of the worm 10.

[0031] In a specific implementation, an axial protrusion 6 a is formed on the cam ring 6 .

[0032] Working principle: The rope-operated clutch switch 4 switches the motor between the electric mode and the manual mode. When the rope-operated clutch switch 4 is in the electric mode, see Figure 4 , the manual device 2 and the motor output shaft 5 are separated, which does not affect the rotation of the motor; when the power is off or the power is cut off, pull the rope-controlled clutch switch 4 to switch to manual mode, see Figure 5 , the power source of the motor output shaft 5 is switched to the manual device 2 by the clutch 3, and the motor can be operated manually by pulling the rope or chain of the manual device 2 to avoid disasters. The specific switching process of switching from electric mode to manual mode: when the rope-controlled clutch switch 4 is pulled to act, the cam ring 6 rotates, and the axial clutch rod 7 can be controlled to move forward or backward. At this time, the axial clutch rod 7 drives the clutch sleeve 8, and the clutch sleeve 8 has a plurality of round pins 8a. By combining the round pins 8a and the round holes 9a on the output sleeve 9, the power source can be switched to the manual device 2 to drive the motor to rotate.
