Example one
In this embodiment, the floating gear includes a first floating gear 32 and a second floating gear 33, and the first floating gear 32 and the second floating gear 33 are respectively disposed on the first side 34 and the second side 35.
The specific working process is as follows: the first power source drives the first transmission gear 21 to rotate clockwise, and then drives the second transmission gear 22 to rotate synchronously, the second transmission gear 22 is meshed with the first floating gear 32 and the second floating gear 33, and further the first floating gear 32 and the second floating gear 33 rotate anticlockwise synchronously, because the floating seat 31 and the rotating shaft 12 and the housing 1 have smaller friction force, and then the selection of the first floating gear 32 and the second floating gear 33 drives the floating seat 31 to rotate anticlockwise, and further the first floating gear 32 is gradually close to the driven gear 41 until being meshed with the driven gear 41, at this time, the second side edge 35 is abutted against the limit strip 11, and further the driven gear 41 and the floating mechanism 3 are kept in a combined state all the time. In a combined state, the transmission mechanism 2 loses the first power source, the second power source drives the driven shaft 42 to rotate counterclockwise, so that the driven gear 41 rotates counterclockwise synchronously, at this time, the driven gear 41 is engaged with the first floating gear 32 to drive the first floating gear 32 to rotate clockwise, the first floating gear 32 drives the second floating gear 33 to rotate clockwise synchronously through the second transmission gear 22, the first floating gear 32 and the second floating gear 33 move to drive the floating seat 31 to move clockwise around the rotating shaft 12, so that the first floating gear 32 is disengaged from the driven gear 41, and at this time, the floating mechanism 3 is separated from the driven mechanism 4.
On the contrary, when the first power source drives the transmission mechanism 2 to rotate counterclockwise, the working principle is opposite to the above process.
In this embodiment, the first side 34 and the second side 35 are respectively provided with the first floating gear 32 and the second floating gear 33, so that the clutch between the driven mechanism 4 and the floating mechanism 3 can be realized when the first power source and the second power source rotate clockwise or counterclockwise, and the power for rotating the floating seat 31 is also increased by the synchronous rotation of the first floating gear 32 and the second floating gear 33.
Example two:
in this embodiment, the floating gear includes a first floating gear 32, and the first floating gear 32 is disposed on the first side 34.
The difference between the motion process and the motion process of the first embodiment is that the first power source is limited to rotate clockwise, and the joint state between the driven gear 41 and the first floating gear 32 can be realized, in the joint state, the first power source loses power, at this time, the second power source applies force in the opposite direction to drive the driven mechanism 4 to rotate counterclockwise, and the clockwise rotation of the first floating gear 32 drives the floating seat 31 to rotate clockwise, so that the driven gear 41 is finally separated from the first floating gear 32, and the motion of the driven gear 41 is not restricted.
Example three:
in this embodiment, the floating gear includes a second floating gear 33, and the second floating gear 33 is disposed at the second side 35.
The difference between the motion process and the motion process of the second embodiment is that the first power source is limited to rotate counterclockwise, and the combined state between the driven gear 41 and the second floating gear 33 can be realized, in the combined state, the first power source loses power, at this time, the second power source applies force in the opposite direction to drive the driven mechanism 4 to rotate clockwise, and the floating seat 31 is driven to rotate counterclockwise by the counterclockwise rotation of the second floating gear 33, so that the driven gear 41 is finally separated from the second floating gear 33, and the motion of the driven gear 41 is not restricted.
In the utility model, the floating mechanism 3 is arranged to restrict the motion of the driven mechanism 4, and the floating seat 31 can quickly realize the clutch with the driven mechanism 4 by a small rotation angle due to the design of the floating seat 31V-shaped mechanism in the floating mechanism 3. The first floating gear 32 and the second floating gear 33 are designed to transmit the movement between the transmission mechanism 2, the floating mechanism 3 and the driven mechanism 4.
Further, an intelligent door lock with a clutch mechanism includes: the driving mechanism 2 is connected with the driving mechanism, the driving mechanism is a first power source, the driven mechanism 4 is connected with the lock core mechanism, and the second power source drives the lock core mechanism to move and drives the driven mechanism 4 to move. The second power source can be external force or another driving force inside the intelligent door lock.
When no external force is applied to the lock core mechanism, when the intelligent door lock driving mechanism moves, the first transmission gear 21 is driven to rotate clockwise, the second transmission gear 22 is driven to rotate synchronously, the second transmission gear 22 is meshed with the first floating gear 32 and the second floating gear 33, the first floating gear 32 and the second floating gear 33 rotate synchronously anticlockwise, the floating seat 31 has smaller friction force with the rotating shaft 12 and the shell 1, the first floating gear 32 and the second floating gear 33 are selected to drive the floating seat 31 to rotate anticlockwise, the first floating gear 32 gradually approaches the driven gear 41 until being meshed with the driven gear 41, at the moment, the second side edge 35 abuts against the limiting strip 11, and the driven gear 41 and the floating mechanism 3 are enabled to be kept in a combined state all the time. In a combined state, when a driving mechanism in the intelligent door lock stops moving, the transmission mechanism 2 loses the first power source, at this time, an external force drives the lock cylinder mechanism to rotate, so as to drive the driven shaft 42 to rotate anticlockwise, so that the driven gear 41 rotates anticlockwise synchronously, at this time, the driven gear 41 is meshed with the first floating gear 32 to drive the first floating gear 32 to rotate clockwise, the first floating gear 32 drives the second floating gear 33 to rotate clockwise synchronously through the second transmission gear 22, the first floating gear 32 and the second floating gear 33 move to drive the floating seat 31 to move clockwise around the rotating shaft 12, so that the first floating gear 32 is separated from the driven gear 41, and at this time, the floating mechanism 3 is separated from the driven mechanism 4.
On the contrary, when the first power source drives the transmission mechanism 2 to rotate counterclockwise, the working principle is opposite to the above process.
In addition, the clutch mechanism may be applied to, including but not limited to, smart door locks.
According to the intelligent door lock, the floating mechanism 3 is driven to move through power transmission of the transmission mechanism 2 and further separated from or meshed with the driven mechanism 4, so that the movement of the driven mechanism 4 is controlled, locking and unlocking of the intelligent door lock are further achieved, the rotation range of the floating mechanism 3 is limited due to the design of the limiting strip 11, and under the condition that only the first power source acts, the floating mechanism 3 and the driven mechanism 4 are always kept in a meshed state after being meshed. In the utility model, the floating seat 31 is mainly used for driving the floating gear to be meshed with or separated from the driven gear 41, wherein the floating seat 31 is designed to have a V-shaped structure, so that the floating mechanism and the driven mechanism can be clutched at a small angle. In addition, the floating gear on the floating seat can not only transmit the motion of the transmission mechanism 2 and the driven mechanism 4, but also provide a power source for the rotation of the floating seat 31. The floating seat 31 is selected to have a V-shaped angle, and the rotation power of the floating gear in the angle range is larger than the friction force between the floating seat 31 and the rotating shaft 12 and between the floating seat 31 and the housing 1, so that the floating seat 31 is driven to rotate by the floating gear. In the utility model, the limit strip 11 is matched with the first side edge 34 and the second side edge 35 of the floating seat 31 to limit the rotation angle of the floating seat 31.
The above description is only for the purpose of illustrating the present invention and is not intended to limit the present invention in any way, and the present invention is not limited to the above description, but rather should be construed as being limited to the scope of the present invention.
