Therefore, in the power switching structure 100 of the present invention, when the motor module fails, the mechanical key cylinder 200 can still be unlocked and locked. Thereby the safety performance can be ensured, and convenience is brought to life.
It should be noted that the electromotive force is the motive power output by the motor module 300, and is divided into an unlocking direction and a locking direction according to the requirement; the mechanical power is the power output by the mechanical lock core 200 and is divided into an unlocking direction and a locking direction according to requirements.
The supporting member 101 is used for supporting the arrangement of the transmission shaft 103, the first transmission member 102, the second transmission member 106, the third transmission member 108, the power coupling member 104, the first elastic member 107 and the second elastic member 105. The support member 101 may be the housing of the lock body or may be provided separately and installed as required.
The first transmission member 102 is configured to receive the electromotive force output by the motor module 300, and when the direction of the electromotive force is the unlocking direction, the first transmission member 102 rotates in the unlocking direction, and when the direction of the electromotive force is the locking direction, the first transmission member 102 rotates in the locking direction. The rotation of the first transmission member 102 is transmitted to the transmission shaft 103 through the power coupling member 104, and then transmitted to the third transmission member 108 through the transmission shaft 103. When the power coupling element 104 is in a coupling state, the first transmission member 102 and the power coupling element 104 can be in transmission connection, and can transmit torque; when the power coupling element 104 is in the non-coupling state, the transmission between the second power room and the power coupling element 104 is separated, and the second power room and the power coupling element 104 can not transmit torque.
The second transmission member 106 is used for receiving the mechanical power output by the mechanical lock cylinder 200, when the direction of the mechanical power is an unlocking direction, the second transmission member 106 moves in the unlocking direction, and when the direction of the mechanical power is a locking direction, the second transmission member 106 moves in the locking direction. The movement of second transmission member 106 may be directly transmitted to third transmission member 108, or may be indirectly transmitted to third transmission member 108.
The second transmission member 106 is slidably disposed on the support member 101 by a fastener. In some embodiments, second transmission element 106 is provided with a sliding slot 1061 slidably engaged with a fastening element, which is fixed to support element 101. Alternatively, the second transmission member 106 is provided with a fastening member, and the supporting member 101 is provided with a chute 1061 in sliding fit with the fastening member. Of course, the second transmission member 106 may be slidably disposed on the supporting member 101 in other manners, and it is within the scope of the present invention to achieve that the second transmission member 106 is slidably disposed on the supporting member 101.
The second transmission part 106 can transmit the mechanical power output by the mechanical lock cylinder 200 to the third transmission part 108, and the second transmission part 106 can also switch the coupling state of the power coupling element 104. In some embodiments of the present invention, an end surface of the second transmission element 106 close to the power coupling element 104 is provided with a first wedge surface 1062, and an end surface of the power coupling element 104 close to the second transmission element 106 is provided with a second wedge surface, and when the second transmission element 106 is under the mechanical power of the mechanical lock cylinder 200, the first wedge surface 1062 and the second wedge surface cooperate to push the power coupling element 104 to move away from the first transmission element 102, so that the power coupling element 104 is switched from the coupled state to the uncoupled state.
The portion of the second transmission member 106 provided with the first wedge surface 1062 is of an integral structure or a split structure with the second transmission member 106, wherein, in the split structure, the portion can be non-detachably connected or detachably connected with the second transmission member 106.
And the portion of the power coupling 104 providing the second wedge surface is of unitary or split construction with the power coupling 104. When the coupling part 104 is in a split structure, the portion of the coupling part 104 provided with the second wedge-shaped surface is a push block 1041, and the push block 1041 is detachably connected or non-detachably connected with the coupling part 104.
The coupling between the power coupling element 104 and the first transmission element 102 is achieved by providing a coupling portion 1042, wherein at least two coupling portions 1042 are disposed on an end surface of the power coupling element 104 close to the first transmission element 102, at least two sections of arc-shaped track grooves 1021 are disposed on an end surface of the first transmission element 102 close to the power coupling element 104, and the coupling state is achieved by sliding fit between the two coupling portions 1042 and the corresponding arc-shaped track grooves 1021.
When the power coupling element 104 is in the coupled state, the first transmission element 102 rotates under the action of the electric power in the unlocking direction, and because the arc-shaped track groove 1021 is in sliding fit with the coupling portion 1042, when the coupling portion 1042 abuts against one end of the arc-shaped track groove 1021, the first transmission element 102 can drive the coupling portion 1042 to rotate by a preset angle; the first transmission member 102 rotates under the action of the electric power in the locking direction, and since the arc-shaped track groove 1021 is in sliding fit with the coupling portion 1042, when the coupling portion 1042 abuts against the other end of the arc-shaped track groove 1021, the first transmission member 102 can drive the coupling portion 1042 to rotate by a predetermined angle.
The power coupling element 104 is directly sleeved on the transmission shaft 103 or is matched with the transmission shaft 103 through a shaft sleeve.
