Further, the power member 321 has a first state and a second state, when the power member 321 is in the first state, the locking member 20 is in the locking position, the transmission member 322 drives the supporting portion 31 to move in the installation slot 11 to a position between the locking member 20 and the bottom wall of the installation slot 11, at this time, the limiting member 50 is in the second limiting position, and the locking device 100 is in the locking state, and is locked with the member to be locked 200. When the power element 321 is in the second state, the transmission element 322 drives the supporting portion 31 to move in the mounting slot 11 to be away from the locking member 20, the locking member 20 rotates to the unlocking position relative to the housing 10, at this time, the locking device 100 is in the unlocking state, the limiting member 50 is in the first limit position, and the locking device 100 is disengaged from the to-be-locked member 200.
Optionally, in one embodiment, the power element 321 includes a power source 3211 and an elastic portion 3212, and the elastic portion 3212 is connected between the transmission element 322 and the power source 3211. The power source 3211 is configured to drive the transmission member 322 to move toward an end away from the locking member 20, so that the elastic portion 3212 elastically deforms and stores an elastic restoring force that enables the transmission member 322 to drive the limiting member 50 to move to the second limit position.
Specifically, when the locking device 100 needs to be disengaged from the to-be-locked member 200, the power source 3211 drives the transmission member 322 to move to an end away from the locking member 20, and the transmission member 322 drives the limiting member 50 to move to the first limit position, at this time, the elastic portion 3212 elastically deforms due to the movement of the transmission member 322, so as to accumulate the elastic restoring force.
If the locking device 100 and the to-be-locked element 200 need to be locked, the power source 3211 is turned off, the elastic restoring force is released, the driving transmission element 322 automatically drives the supporting portion 31 to move to a side close to the locking element 20, the driving transmission element 322 drives the limiting element 50 to move to the second limit position and then stops, and the supporting frame is supported between the locking element 20 located at the locking position and the bottom wall of the mounting groove 11, so that the locking device 100 is automatically switched between the unlocking state and the locking state.
Moreover, after the elastic restoring force driving transmission member 322 automatically drives the supporting portion 31 to move to a side close to the locking member 20 and drives the limiting member 50 to move to the second limit position, the elastic restoring force may be completely released or may not be completely released.
In one embodiment, the power source 3211 is an electromagnet, the transmission element 322 is an iron core, and the electromagnet is powered to drive the iron core to move toward an end away from the locking element 20, so that the elastic portion 3212 accumulates an elastic restoring force. If the electromagnet is powered off, the iron core is not stressed any more, the iron core is driven by elastic restoring force at the moment, the iron core drives the supporting part 31 and the limiting part 50 to move, and the whole locking process is completed in the state that the electromagnet is powered off.
