DETAILED DESCRIPTION

[0027] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0028] See also Figure 1-12 The utility model provides an embodiment: an electric operating mechanism, including a driving member 3, the driving member 3 includes a housing 30, and a motor 33 and a reduction gear set 32 ​​are arranged in the housing 30; the reduction gear set 32 ​​includes a worm 31 installed on the output shaft of the motor 33, the worm 31 is meshed with a worm wheel 34, and the worm wheel 34 is meshed with a second gear 35; the second gear 35 is meshed with a third gear 36, and the third gear 36 outputs the power of the motor 33 through a provided output gear 37.

[0029] In summary, the motor 33 and the reduction gear set 32 ​​are integrated inside the housing 30, so that under the action of the reduction gear set 32, the output torque of the motor 33 is increased, so that the power and volume of the motor 33 can be reduced.

[0030] The worm gear 34 , the second gear 35 and the third gear 36 all include a large ring gear 311 and a small ring gear 312 , so that the reduction gear set 32 ​​can mesh with each other smoothly to achieve reliable power output.

[0031] Furthermore, since the output gear 37 includes fine teeth 313 and coarse teeth 38 , and the fine teeth 313 mesh with the large gear ring 311 of the third gear 36 , the power can be output to the outside through the large gear ring 311 while receiving the power of the motor 33 .

[0032] At the same time, since the outer diameter of the fine teeth 313 is equal to the outer diameter of the coarse teeth 38 , the output gear 37 can be further used to reduce the rotation speed to increase the torque.

[0033] Specifically, the second gear 35 has the same structure as the third gear 36, and the number of teeth of the large gear ring 311 of the second gear 35 is 18, and the number of teeth of the small gear ring 312 of the second gear 35 is 10. The number of teeth of the large gear ring 311 of the worm gear 34 is 18, and the number of teeth of the small gear ring 312 of the worm gear 34 is 10. The number of teeth of the fine teeth 313 is 24, and the number of teeth of the coarse teeth 38 is 12. In the above manner, the reduction gear set 32 ​​can ensure the increase of torque while ensuring reliable power output.

[0034] On the basis of the above scheme, since the driving member 3 also includes a cover plate 39, the cover plate 39 is adapted to be connected to the housing 30 to cover the motor 33 and the reduction gear set 32 ​​in the housing 30, thereby ensuring that the reduction gear set 32 ​​has a reliable working environment.

[0035] Furthermore, since the facing surfaces of the housing 30 and the cover plate 39 are both provided with a receiving groove 310 for receiving the motor 33, the position of the motor 33 is stable and reliable during operation, thereby reducing the phenomenon of the worm 31 and the worm wheel 34 on the motor 33 falling off.

[0036] Specifically, Figure 11-12 As shown, when the driving mechanism is applied to the lock, the output gear 37 is engaged with the paddle 1 to cause the paddle 2 to rotate, thereby driving the brake pin 4 to smoothly disengage from the retaining groove on the side of the lock tongue 5; since the driving mechanism has a large torque and a small size, the driving mechanism does not take up space after installation.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
