Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiment of the present invention, all other embodiments obtained by the person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-8, a gear clutch mechanism 1000 is shown. Wherein the gear clutch mechanism 1000 includes a left cover 110, a right cover 120, an input gear set 200, a first sun gear 310, a second sun gear 311, a floating plate 321, a planet shaft 333, a damping member 331, a clutch gear 330, and an output gear 410, the input gear set 200 is engaged with the first sun gear 310,
the second sun gear 311 is disposed coaxially with the first sun gear 310,
the floating plate 321 is provided to be rotatable around the central axis of the second sun gear 311,
the planet shaft 333 is fixedly provided to the floating plate 321,
the clutch gear 330 is connected to the planetary shaft 333 through the damping member 331,
the inner side of the right cover 120 is provided with an arc-shaped limiting groove 122,
the free end 334 of the planet axle 333 is located in the arc-shaped limiting groove 122.
The second sun gear 311 and the first sun gear 310 are coaxial gears. And a boss 312 is provided between the first sun gear 310 and the second sun gear 311 for engaging with an inner hole 322 of the floating plate 321, so that the floating plate 321 can rotate along a central axis of the boss 312.
Meanwhile, the floating plate 321 is provided with a first planetary hole 324 for mounting the planetary shaft 333 and the clutch gear 330, and the clutch gear 330 can rotate around the planetary shaft 333.
In the present embodiment, both ends of the clutch gear 330 are provided with damping members 331. The damping member 331 functions to provide resistance to the rotation of the planet shaft 333 and the clutch gear 330 along the central axis of the boss 312 following the floating plate 321, and to prevent the clutch gear 330 from rotating around the planet shaft 333 because the resistance of the clutch gear 330 and the planet shaft 333 is too small. But when the driving force is greater than the maximum resistance force provided by the damping member 331, the clutch gear 330 can rotate about the planet shaft 333.
In this embodiment, the free end 334 of the planet axle 333 is mounted in the second planet hole 328 of the auxiliary reinforcing plate 325, and the free end 334 protrudes out of the right side of the auxiliary reinforcing plate 325 to be engaged with the arc-shaped retaining groove 122 provided inside the right cover 120. The engagement of the free end 334 with the arc-shaped retaining groove 122 provides a limit location for the clutch gear 330 to rotate following the floating plate 321. When the free end 334 is at the extreme point of the arc-shaped limiting groove 122, the clutch gear 330 and the output gear 410 are just at the optimal meshing point.
In addition, the floating plate 321 and the reinforcing plate 325 are respectively provided with a first pin hole 323 and a second pin hole 327 for mounting the pin shaft 340. Thus, the floating plate 321, the sub-reinforcing plate 325, the planetary shaft 333, and the clutch gear 330 form a planetary mechanism, and rotate around the central axis of the second sun gear 311.
In the present embodiment, the first sun gear 310, the second sun gear 311, and the planetary mechanism described above are all rotatable about the sun gear shaft 350, constituting the clutch assembly 300. When the motor drives the input gear set 200 to mesh with the first sun gear 310 for transmission, the clutch assembly 300 rotates around the sun gear shaft 350 to drive the clutch gear 330 to rotate to the limit position point, so that the clutch gear 330 meshes with the output gear 410. At this time, the clutch gear 330 drives the output gear 410 to rotate, completing power transmission.
When the output gear 410 is manually rotated in the reverse direction, since the floating plate 321 can rotate along the central axis of the boss 312, the clutch gear 330 in the clutch assembly 300 also rotates along with the floating plate 321, so that the clutch gear 330 is disengaged from the output gear 410. Thereby disengaging the output gear 410 from the clutch assembly 300. At the moment, the manual operation is not affected by the motor transmission assembly, so that the manual operation is more convenient and faster.
As shown in fig. 3, the central axis of the output gear 410 is provided with a hexagonal insertion hole 413 having a hexagonal cross section. Wherein the hexagonal socket 413 is used for connecting with an external connection driving member. In other embodiments, the jacks can be arranged in different shapes according to actual needs.
As shown in fig. 2 and 3, the gear clutch mechanism 1000 further includes a first ball bearing 421 and a second ball bearing 422, the output gear 410 is connected to the left cover 110 through the first ball bearing 421, and the output gear 410 is connected to the right cover 120 through the second ball bearing 422. Wherein the bearing connection is employed in order to reduce the frictional force between the output gear 410 and the left and right covers 110 and 120.
As shown in fig. 2 to 6, the gear clutch mechanism further includes an auxiliary reinforcing plate 325, and the auxiliary reinforcing plate 325 is connected to the floating plate 321 by a plurality of pins 340.
As shown in fig. 2 and 3, the damping member 331 is a damping ring, and the number of the damping members 331 is 2 or more. In the present embodiment, the damping member 331 functions to provide resistance to the rotation of the clutch gear 330 about the planetary shaft 333. Since the clutch gear 330 is attached to the floating plate 321 and engaged with the second sun gear 311, if the resistance between the clutch gear 330 and the planetary shaft 333 is excessively small when the second sun gear 311 rotates, the clutch gear 330 rotates only around the planetary shaft 333 by the urging force between the second sun gear 311 and the clutch gear 330. At this time, the floating plate 321 is relatively stationary, and the clutch effect cannot be achieved. Similarly, when the output gear 410 is manually rotated, if the resistance between the clutch gear 330 and the planetary shaft 333 is too small, the clutch effect cannot be achieved. Therefore, the damping member 331 functions to provide a certain resistance between the clutch gear 330 and the planet shaft 333, so that the clutch gear 330 can follow the floating plate 321 to rotate, thereby achieving a clutch effect.
As shown in fig. 2 to 7, the input gear set 200 includes a first input gear 210 and a second input gear 211 coaxially disposed with the first input gear 210, the second input gear 211 being engaged with the first sun gear 310.
An intelligent door lock comprises a motor and a gear clutch mechanism 1000 shown in the embodiment, wherein the gear clutch mechanism 1000 is the gear clutch mechanism 1000 shown in fig. 1. And the motor is in power connection with the input gear set 200, and since the power connection of the motor and the input gear set 200 is gear engagement connection, which is common in the art, it is not described herein again.
One typical operation of the gear clutch mechanism 1000: when the motor is driven, the motor drives the input gear set 200 to mesh with the first sun gear 310 for transmission. At this time, the clutch assembly 300 rotates around the sun gear shaft 350, and the clutch gear 330 rotates following the floating plate 321 due to the resistance of the damping member 331 until the free end 334 of the planet shaft 333 is at the limit point of the arc-shaped limit groove 122. At this time, the clutch gear 330 is engaged with the output gear 410. As the motor continues to rotate, the clutch gear 330 drives the output gear 410 to rotate, completing the electric power transmission.
When the output gear 410 is manually driven, the clutch gear 330 engaged with the output gear 410 rotates along with the floating plate 321 until the output gear 410 is disengaged from the clutch gear 330. At this time, the power of the manual driving cannot be transmitted to the component part of the electric driving, so that the manual driving is not affected by the electric driving component, and the smoothness of the manual driving is ensured.
In conclusion, the gear clutch mechanism 1000 can realize rapid switching between electric driving and manual driving, and is convenient and rapid.
