In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, the utility model provides an intelligent lock 1, include: the power switching device comprises an operating part 10, a power transmission part 30 and a power switching device, wherein the operating part 10 is provided with a first rotating shaft 20, the first rotating shaft 20 is connected with the power transmission part 30, the operating part 10 is used for being held by a user to drive the first rotating shaft 20 to rotate in a first direction (shown in the direction A in figure 1) or a second direction (shown in the direction B in figure 1) in the circumferential direction, and the first direction is opposite to the second direction; alternatively, the operation portion 10 is a door handle; alternatively, the operation portion 10 is a knob.

The power switching device further includes a transmission mechanism 40, the transmission mechanism 40 is connected to the power transmission unit 30 and a generator 41, respectively, and when the first shaft 20 rotates in the circumferential direction, the transmission mechanism 40 can transmit power to the generator 41 to generate power by the generator 41 in a power generation system; when the first shaft 20 rotates in the first direction, the power transmission unit 30 establishes power transmission between the first shaft 20 and the transmission mechanism 40, and when the operation unit 10 is rotated, the generator 41 can generate power. When the first shaft 20 rotates in the second direction, the power transmission unit 30 blocks the power transmission between the first shaft 20 and the transmission mechanism 40, and the generator 41 does not generate power when the operation unit 10 is rotated.

That is, the present invention provides an operation unit 10 that transmits the torque in the first direction to a generator 41 through a power transmission unit 30 during the reciprocating rotational motion in the first direction and the second direction, and the rotational direction of the input shaft of the generator 41 is kept unchanged, and the rotation is not repeated, thereby prolonging the service life of the generator 41. The reciprocating rotation of the operation unit 10 is finally converted into unidirectional rotation of the generator 41 in accordance with the mechanical inertia of the power generation system, thereby continuously outputting the power supply.

Equivalently, the power transmission unit 30 of the present invention realizes unidirectional power transmission. Alternatively, the power transmission portion 30 includes a one-way bearing, a one-way clutch, or a ratchet mechanism. However, the specific type of the power transmission unit 30 is not limited thereto, and one-way power transmission may be achieved.

Referring to fig. 1 and 2, in the embodiment, the power transmission portion 30 is a one-way bearing, an inner ring of the one-way bearing is sleeved on the first rotating shaft 20, an outer ring of the one-way bearing is sleeved with a driving gear 21, and the driving gear 21 is connected with the transmission mechanism 40. When the operation part 10 rotates in the first direction, the driving gear 21 is driven to rotate by the one-way bearing, and when the operation part 10 rotates in the second direction, the inner ring and the outer ring of the one-way bearing slip, and at this time, the torque of the first rotating shaft 20 connected to the operation part 10 cannot be transmitted to the driving gear 21 by the one-way bearing. By the continuous reciprocating rotation of the operation part 10, only one rotation direction of the driving gear 21 is always provided, and thus the driving gear 21 transmits power to the transmission mechanism 40 only in the first direction to drive the generator 41 to generate electricity.

However, the specific type of the transmission mechanism 40 that transmits the torque of the first shaft 20 to the generator 41 is not limited, and the torque transmission may be realized. In this embodiment, referring to fig. 1, the transmission mechanism 40 is a gear structure. Optionally, the transmission mechanism 40 includes: a second rotating shaft 50, the second rotating shaft 50 being parallel to the first rotating shaft 20, a first gear 51 (refer to fig. 5) and a second gear 52 being provided at intervals along an axial direction of the second rotating shaft 50, the first gear 51 being engaged with the driving gear 21; and a third rotating shaft 53, wherein the third rotating shaft 53 is parallel to the second rotating shaft 50, a third gear 54 and a fourth gear 55 are arranged at intervals along the axial direction of the third rotating shaft 53, the third gear 54 is meshed with the second gear 52, and the fourth gear 55 is meshed with a fifth gear 56 arranged on the input shaft of the generator 41.

Therefore, when the operation unit 10 drives the first rotating shaft 20 to rotate in the first direction, the power transmission unit 30 drives the driving gear 21 to rotate, and then the torque is sequentially transmitted to the first gear 51, the second rotating shaft 50, the second gear 52, the third gear 54, the third rotating shaft 53, the fourth gear 55, the fifth gear 56, the input shaft of the generator 41, and the generator 41 continuously outputs and supplies power.

It should be noted that the present invention is not limited to the above gear structure, and in other embodiments, other numbers of gears may be provided according to the torque transmission requirement. For example, referring to fig. 5, the transmission mechanism 40 further includes a fourth rotating shaft 57, the fourth rotating shaft 57 is parallel to the third rotating shaft 53, a sixth gear 58 and a seventh gear 59 are arranged at intervals along the axial direction of the fourth rotating shaft 57, the sixth gear 58 is meshed with the second gear 52, and the seventh gear 59 is meshed with the third gear 54.

Optionally, the total gear ratio between the drive gear 21 to the fifth gear 56 is between 1: 300 and 1: 50, including 1: 300 and 1: 50. Optionally, the total transmission ratio between the driving gear 21 and the fifth gear 56 is 1: 100. Thus, the speed and torque of the user for swinging the operation part 10 can be adapted, and the electric power generated by the micro-generator 41 is sufficient; in addition, an acceleration effect can be achieved, and it is relatively labor-saving for the user to swing the operation unit 10.

The gear transmission ratio between the driving gear 21 and the fifth gear 56 is not limited, and the total gear ratio between the driving gear 21 and the fifth gear 56 may be satisfied.

As previously mentioned, the specific type of drive mechanism 40 is not limiting, and with reference to FIG. 3, the drive mechanism 40 is a belt drive configuration. In other embodiments, the transmission mechanism 40 may also be a turbine worm gear mechanism 40, a linkage mechanism, or other mechanism capable of transmitting torque.

Referring to fig. 4, the power switching device of the intelligent lock 1 of the present invention further includes: a transmission rotation shaft 43, the transmission rotation shaft 43 being parallel to the first rotation shaft 20; and a transmission frame 42 rotatable about the transmission rotation shaft 43 between a first position and a second position, the transmission frame 42 mounting the transmission 40 and the generator 41. Wherein, with reference to fig. 5 and 6, in said first position, power transmission between said first shaft 20 and said transmission 40 is established; referring to fig. 7 and 8, in the second position, the power transmission between the first shaft 20 and the transmission mechanism 40 is cut off.

That is, by switching the position of the transmission mechanism frame 42, in which the generator 41 can generate electricity by rotating the operation unit 10 in the first direction, the establishment or the interruption of the power transmission between the first rotating shaft 20 and the transmission mechanism 40 is realized; in the second position, the generator 41 does not generate power by rotating the operation portion 10 in the first direction. When the power supply capacity of the intelligent lock 1 is sufficient, the power transmission between the transmission mechanism 40 of the power generation system and the first rotating shaft 20 of the intelligent lock 1 can be cut off by the device, and the power generation and supply can be stopped. When the power supply of the intelligent lock 1 is insufficient, the emergency power generation system needs to be started, the power transmission between the transmission mechanism 40 of the power generation system and the first rotating shaft 20 of the intelligent lock 1 is established through the device, power generation is started, and the power supply is provided for the whole system. The generator 41 does not need to work all the time to generate electricity, and works to generate electricity when needed, so that the service life of the generator 41 is prolonged. Moreover, because the power switching is realized, the phenomenon that the generator 41 idles and has extra load when the normal unlocking is carried out when the power generation is not needed is avoided; thereby when the user normally unblanks, the dynamics of using is little, and this dynamics is big when solving normally unblanking simultaneously experiences relatively poor problem.

In the present embodiment, referring to fig. 5, in the first position, the driving gear 21 is engaged with the first gear 51, the power transmission between the driving gear 21 and the first gear 51 is established, and the transmission mechanism 40 of the power generation system can obtain power from the driving gear 21 and generate power; referring to fig. 7, in the second position, the drive gear 21 and the first gear 51 are separated, the power transmission between the drive gear 21 and the first gear 51 is cut off, the power transmission mechanism 40 of the power generation system loses power and stops generating power.

Further, referring to fig. 4, the smart lock 1 further includes: and a transmission mechanism rocking handle 44 connected with the transmission mechanism frame 42 and used for driving the transmission mechanism frame 42 to rotate around the transmission mechanism rotating shaft 43 between a first position and a second position. Referring to fig. 5 and 7, shifting the transmission rocking handle 44 left and right can rotate the transmission frame 42 of the power generation system around the transmission rotating shaft 43, thereby moving the transmission 40. In this embodiment, the rotation of the transmission frame 42 around the transmission rotation shaft 43 drives the first gear 51 to move, so as to control the engagement or disengagement of the first gear 51 and the driving gear 21.

With continued reference to fig. 4, the smart lock 1 further includes: and the limiting mechanism 46 is used for limiting the transmission mechanism rocking handle 44 at the first position or the second position. After the limiting mechanism 46 is arranged, the transmission mechanism rocking handle 44 is kept at the first position or the second position, so that the first gear 51 is reliably meshed with or separated from the driving gear 21, the selection of the power generation time of the generator 41 is conveniently realized, and the normal work of other parts of the intelligent lock 1 cannot be influenced.

Specifically, referring to fig. 6 and 8, the limiting mechanism 46 includes a clamp spring, the clamp spring includes a first perforation 461 and a second perforation 462 for the transmission mechanism rocking handle 44 to pass through, and the first perforation 461 and the second perforation 462 are connected by a transition channel 463; wherein, with reference to FIG. 6, in the first position, the transmission rocker 44 is located in the first aperture 461; referring to FIG. 8, in the second position, the transmission rocker 44 is located in the second bore 462; under the action of an external force, the transmission rocker 44 can pass through the transition channel 463 to transition to the first perforation 461 or the second perforation 462, and the transition channel 463 is deformed in a pressing manner during the process of passing the transmission rocker 44 through the transition channel 463.
