[0027] See the appendix Figures 1-5As shown in the figure, an embodiment of the present utility model provides a clutch manual device for a speed reduction motor, which includes a lower housing 1 and an upper housing 2. The upper housing 2 is fixedly installed on the lower housing 1 by screws. The lower housing 1 and the upper housing 2 form a housing. One end of the lower housing 1 is fixedly installed with a motor 3. A manual input shaft 6 is rotatably installed on one side of the lower housing 1. An output shaft 5 is rotatably installed at one end of the housing away from the motor 3. An output transmission member for driving the output shaft 5 to rotate is provided inside the housing. The manual input shaft 6 is in transmission connection with the output transmission member through a manual transmission member. A motor transmission member with a clutch mechanism is provided inside the housing. The motor 3 is in transmission connection with the output transmission member through the motor transmission member. The clutch mechanism can disconnect the power transmission between the motor 3 and the output transmission member.

[0028] In the embodiment of the present utility model, the output transmission member includes a first output transmission gear 10, a second output transmission gear 1001, an output transmission bevel gear 1002, and a third output transmission gear 11. The third output transmission gear 11 is fixedly sleeved on the output shaft 5. The first output transmission gear 10 meshes with the third output transmission gear 11. The first output transmission gear 10, the second output transmission gear 1001, and the output transmission bevel gear 1002 are all sleeved on the same rotating shaft. The second output transmission gear 1001 is located between the first output transmission gear 10 and the output transmission bevel gear 1002. The motor transmission member includes a first motor transmission gear 7, a second motor transmission gear 701, a fourth motor transmission gear 9, and a fifth motor transmission gear rotatably installed inside the housing. The first motor transmission gear 7 and the second motor transmission gear 701 are fixedly sleeved on the same rotating shaft. The fourth motor transmission gear 9 and the fifth motor transmission gear are fixedly sleeved on the same rotating shaft. The first motor transmission gear 7 meshes with the gear at the output end of the motor 3. The fifth motor transmission gear meshes with the second output transmission gear 1001. The second motor transmission gear 701 can be in transmission connection with the fourth motor transmission gear 9 through the clutch mechanism;

[0029] The clutch mechanism includes a rotating shaft 8. An upper limit sleeve 806 is fixedly installed on the upper housing 2, and a lower limit sleeve 803 is fixedly installed on the lower housing 1. The upper end of the rotating shaft 8 is slidably inserted into the upper limit sleeve 806, and the lower end of the rotating shaft 8 is slidably inserted into the lower limit sleeve 803. A mode switching gear 801 and a third motor drive gear 802 are fixedly sleeved on the rotating shaft 8 respectively. The mode switching gear 801 can be engaged with a fourth motor drive gear 9, and the third motor drive gear 802 is engaged with a second motor drive gear 701. By pressing down the rotating shaft 8, the mode switching gear 801 can be separated from the fourth motor drive gear 9. To facilitate pressing down the rotating shaft 8 for mode switching, a clutch cam 4 is rotatably installed on the upper housing 2. A height-varying notch 401 is formed at the bottom of the clutch cam 4. The lower end of the rotating shaft 8 is sleeved with a first spring 804. The bottom of the first spring 804 presses on the lower limit sleeve 803, and the top of the first spring 804 abuts against the bottom of the third motor drive gear 802. The lower surface of the height-varying notch 401 is in sliding contact with the top of the rotating shaft 8. When the lowest point of the height-varying notch 401 contacts the top of the rotating shaft 8, the rotating shaft 8 is squeezed downward, so that the mode switching gear 801 is separated from the fourth motor drive gear 9.

[0030] In the embodiment of the present utility model, the motor 3 drives the output shaft 5 to rotate through five-stage speed change (the speed ratio is 750). Among them, when the motor 3 is powered on, the rotational speed is 2700 revolutions per minute, then the rotational speed of the output shaft 5 is 3.6 revolutions per minute.

[0031] During operation, the gear on the motor 3 drives the first motor drive gear 7 to rotate. The first motor drive gear 7 drives the second motor drive gear 701 to rotate. The second motor drive gear 701 is engaged with the third motor drive gear 802, and then drives the mode switching gear 801 to rotate. The mode switching gear 801 is engaged with the fourth motor drive gear 9, and then drives the fifth motor drive gear installed on the same rotating shaft as the fourth motor drive gear 9 to rotate. The fifth motor drive gear is engaged with the output drive bevel gear 1002, and then drives the first output drive gear 10 installed on the same rotating shaft as the output drive bevel gear 1002 to rotate. Then, the first output drive gear 10 drives the output shaft 5 to rotate through the third output drive gear 11.

[0032] When the motor 3 cannot be used due to power failure or damage, switch to the manual mode for operation. By rotating the clutch cam 4, rotate the lowest point of the height-varying notch 401 to the top of the rotating shaft 8. At this time, the rotating shaft 8 is pressed downward and moves, and then drives the mode switching gear 801 to move downward, so that the mode switching gear 801 is separated from the fourth motor drive gear 9, thereby realizing the manual mode switching.

[0033] When it is necessary to switch to the automatic mode, rotate the clutch cam 4 to move the lowest point of the height-varying notch 401 out of the rotating shaft 8, so that the rotating shaft 8 continuously moves upward under the elastic force of the first spring 804, thereby enabling the mode-switching gear 801 to re-engage with the fourth motor transmission gear 9, realizing the automatic mode-switching operation.

[0034] Among them, the manual transmission member includes a manual input transmission bevel gear 601, which meshes with an output transmission bevel gear 1002. The manual input transmission bevel gear 601 is fixedly installed at one end of a manual input shaft 6. By adopting the above solution, after switching to the manual mode, by connecting a crank to the manual input shaft 6, the manual input transmission bevel gear 601 can be driven to rotate by rotating the crank. Since the manual input transmission bevel gear 601 meshes with the output transmission bevel gear 1002, the first output transmission gear 10 installed on the same rotating shaft as the output transmission bevel gear 1002 is driven to rotate, and then the first output transmission gear 10 drives the output shaft 5 to rotate through the third output transmission gear 11.

[0035] In the embodiment of the present utility model, the manual input transmission bevel gear 601 has fifteen teeth, the output transmission bevel gear 1002 has twenty-two teeth, the first output transmission gear 10 has twelve teeth, and the third output transmission gear 11 has forty teeth, so that the output shaft 5 rotates one circle when the crank rotates 5.25 circles.

[0036] A protective cover 602 for protecting the manual input shaft 6 is provided on the outer wall of the lower housing 1. A groove is provided on the outer wall of the lower housing 1, and the protective cover 602 is stuck in the groove. The manual input shaft 6 is located inside the protective cover 602. By providing the protective cover 602, when the manual mode is not in use, the protective cover 602 can be covered on the lower housing 1 to protect the manual input shaft 6, avoiding the rotating manual input shaft 6 from causing harm to the surrounding personnel in the automatic mode.

[0037] The basic principles of the present invention have been shown and described above. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. The descriptions in the above embodiments and the specification only illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent replacements, and improvements made within the spirit and scope of the present invention shall be included in the protection scope of the present invention.
