Referring to fig. 1-2, one embodiment of the present application provides a locking device 100 that can be mounted on a vehicle body. The battery is used for locking the battery on the vehicle body, so that the pure electric energy automobile is provided, and the pure electric energy automobile can be assembled on other structures, so that the locking function is realized.
Specifically, the locking device 100 includes a housing 10, a locking member 20 and a supporting component 30, the housing 10 has a mounting groove 11, the locking member 20 is used for being matched with the member to be locked 200, so as to lock the member to be locked 200 on the locking member 20, the locking member 20 is assembled in the mounting groove 11 and has a locking position and an unlocking position, and the locking member 20 can rotate in the mounting groove 11 under the force of the locking member 20 relative to the housing 10 so as to switch between the locking position and the unlocking position.
When the locking member 20 is switched to the locking position, the member to be locked 200 and the locking member 20 are locked, and when the locking member 20 is switched to the unlocking position, the member to be locked 200 and the locking member 20 are separated. The support portion 31 is provided in the installation groove 11, and the support portion 31 has a support portion 31 movable toward or away from the lock member 20 side in the installation groove 11, and when the lock member 20 is switched to the lock position, the support portion 31 is moved between the lock member 20 and the bottom wall of the installation groove 11 to support the lock member 20 in the lock position, and when the lock member 20 is switched to the unlock position, the support portion 31 is moved to be completely separated from the lock member 20 to withdraw the supporting force.
As before, when the locking member 20 is not stressed, the locking member 20 is still at the unlocking position, and the locking device 100 is in the unlocking state as shown in fig. 3 to 4, and after the locking member 20 is rotated to the locking position relative to the housing 10 and the member 200 to be locked is cooperatively locked, the supporting portion 31 is moved to between the locking member 20 and the bottom wall of the mounting groove 11 to support, thereby fixing the locking member 20 at the locking position, and the locking device 100 is in the locking state as shown in fig. 5 to 6. When the to-be-locked member 200 needs to be separated from the locking member 20, the control supporting portion 31 moves reversely, and the locking member 20 loses the supporting force of the supporting portion 31 and rotates reversely from the locking position to the unlocking position, so that the locking and unlocking of the locking device 100 are easily achieved.
It will be appreciated that the to-be-locked member 200 may be secured to an external battery related assembly, thereby achieving the technical effect of easy and convenient disassembly of the battery, and may be secured to other structural assemblies requiring locking.
Alternatively, in one embodiment, as shown in fig. 2, the locking member 20 includes a locking slot 22 and an opening in communication with the locking slot 22, through which the member 200 to be locked enters and is secured within the locking slot 22 when the locking member 20 is switched from the unlocked position to the locked position. When the locking member 20 is switched from the locking position to the unlocking position, the member to be locked 200 is disengaged from the locking groove 22 from the opening.
Thus, by the rotation of the locking member 20, the opening locking groove 22 and the change of the opening orientation thereof are realized, and in the process that the member to be locked 200 gradually approaches the locking groove 22, the locking member 20 gradually rotates from the unlocking position to the locking position until the member to be locked 200 gradually enters the locking groove 22 from the opening, and when the member to be locked 200 is locked in the locking groove 22, the supporting portion 31 is removed, at this time, the locking member gradually rotates from the locking position to the end position due to the gravity, and the member to be locked 200 gradually disengages from the locking groove 22 from the opening, at this time, the member to be locked 200 is detached.
Alternatively, in one of the embodiments, the locking member 20 has an active end 21, the active end 21 is rotatably connected to the housing 10, and the active end 21 is forced to rotate the locking member 20 relative to the housing 10 to switch from the unlocked position to the locked position. When the to-be-locked piece 200 is required to be locked on the locking piece 20, only external transmission force is required to enable the acting end 21 to bear force to drive the locking piece 20 to integrally rotate.
Preferably, the to-be-locked member 200 is controlled to perform linear motion, as shown in fig. 7 and 8, the to-be-locked member 200 is controlled to perform linear motion along the positive Y direction until gradually approaching the acting end 21 until abutting against the acting end 21, at this time, the further movement of the acting end 21 drives the locking member 20 to rotate relative to the housing 10, the locking groove 22 and the opening thereof gradually engage with the to-be-locked member 200, so that the to-be-locked member 200 directly enters the locking groove 22 through the opening in the moving process, and at this time, the supporting portion 31 is moved between the locking member 20 and the bottom wall of the mounting groove 11, thereby completing the locking of the to-be-locked member 200. The unlocking process is opposite to the unlocking process, and is not described in detail herein.
Specifically, a pin may be provided to rotatably connect the active end 21 to the housing 10. Further, the locking member 20 further includes a rotating end 23 opposite to the acting end 21, the acting end 21 is forced to drive the rotating end 23 to rotate relative to the housing 10, and the acting end 21 and the rotating end 23 enclose a mounting groove 11. When the locking member 20 is in the unlocked position, the rotating end 23 is located within the mounting groove 11 and is in contact with the bottom wall of the mounting groove 11. When the locking member 20 is in the locking position, the rotating end 23 rotates around the pin to be separated from the mounting groove 11, and at this time, the control support portion 31 is supported between the rotating end 23 and the bottom wall of the mounting groove 11, as shown in fig. 8, so that the state switching of the locking member 20 is realized.
In one embodiment, the supporting portion 31 may be a cushion block, or may be other structures, which is not limited herein.
In one embodiment, the locking device 100 further includes a limiting member 50, the limiting member 50 is connected to the supporting portion 31, the side wall of the housing 10 is correspondingly provided with a sliding groove 12, and the limiting member 50 is slidably disposed in the sliding groove 12. The limiting member 50 has a first limit position and a second limit position in the sliding groove 12, when the limiting member 50 is located at the first limit position, the supporting portion 31 is separated from the locking member 20, and when the limiting member 50 is located at the second limit position, the supporting portion 31 is supported between the locking member 20 and the bottom wall of the mounting groove 11. In this way, the first and second limit positions limit the movement of the supporting portion 31 in the mounting groove 11, so that the limit positions thereof are limited, and the movement process of the supporting portion 31 is reproducible, that is, the supporting portion 31 can reach the same position during each switching process.
The stopper 50 can slide reciprocally in the sliding groove 12 between the first and second stopper positions, and the user can control the stopper 50 manually to automatically move the supporting portion 31.
In one embodiment, as shown in fig. 1 and 2, the supporting assembly 30 further includes a driving mechanism 32, where the driving mechanism 32 is in driving connection with the supporting portion 31 to drive the supporting portion 31 to move toward a side close to or far from the locking member 20 in the mounting groove 11, so that when the locking member 20 rotates to the locking position, the driving mechanism 32 drives the supporting portion 31 to automatically move and drives the limiting member 50 to move to the second limit position, and at this time, the supporting portion 31 is supported between the rotating end 23 and the bottom wall of the mounting groove 11. When the locking state of the locking device 100 needs to be released, the driving mechanism 32 drives the supporting part 31 to automatically move to a first limit position away from the locking piece 20 to the first limit piece 50, and at this time, the supporting force of the rotating end 23 disappears, and rotation is generated to be separated from the piece 200 to be locked, so that the automatic locking and the automatic unlocking of the piece 200 to be locked and the locking piece 20 are realized.
Specifically, the driving mechanism 32 includes a power member 321 and a transmission member 322, and the power member 321 and the transmission member 322 are both assembled in the mounting groove 11, so as to achieve a compact structure of the locking device 100.
And, one end of the transmission member 322 is connected with the supporting portion 31, and the other end is movably connected with the power member 321, and the power member 321 is used for driving the transmission member 322 to drive the supporting portion 31 to move towards one side close to or far away from the locking member 20, i.e. the power member 321 provides power for the transmission member 322 to drive the supporting portion 31 to move.
Further, the power member 321 has a first state and a second state, when the power member 321 is in the first state and the locking member 20 is in the locking position, the transmission member 322 drives the supporting portion 31 to move between the locking member 20 and the bottom wall of the mounting groove 11 in the mounting groove 11, and at this time, the limiting member 50 is in the second limit position, and the locking device 100 is in the locking state and is locked with the member 200 to be locked. When the power member 321 is in the second state, the transmission member 322 drives the supporting portion 31 to move away from the locking member 20 in the mounting groove 11, 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 member 321 includes a power source 3211 and an elastic portion 3212, and the elastic portion 3212 is connected between the transmission member 322 and the power source 3211. The power source 3211 is configured to drive the transmission member 322 to move toward an end far from the locking member 20 so that the elastic portion 3212 elastically deforms to store an elastic restoring force that can drive the transmission member 322 to move the stopper 50 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 the end far away from the locking member 20 to the transmission member 322 to drive the limiting member 50 to move to the first limit position, and at this time, the elastic portion 3212 is elastically deformed 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 piece 200 are locked, the power source 3211 is turned off, at this time, the elastic restoring force is released, the driving piece 322 is driven to automatically drive the supporting portion 31 to move to a side close to the locking piece 20, at this time, the driving piece 322 drives the limiting piece 50 to move to the second limit position and then to stop, and the supporting frame is supported between the locking piece 20 located at the locking position and the bottom wall of the mounting groove 11, so that automatic switching from the unlocking state to the locking state of the locking device 100 is realized.
The elastic restoring force drives the transmission member 322 to automatically drive the supporting portion 31 to move to a side close to the locking member 20, and drive the limiting member 50 to move to the second limit position, and then the elastic restoring force can be completely released or not completely released.
In one embodiment, the power source 3211 is an electromagnet, the transmission member 322 is an iron core, and the electromagnet is powered to drive the iron core to move toward an end far from the locking member 20, and at this time, the elastic portion 3212 accumulates elastic restoring force. If the electromagnet is powered off, the iron core is not stressed any more, and 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 electromagnet power-off state.
In one embodiment, the locking device 100 further includes a signal assembly 40 and a controller (not shown), and when the locking member 20 is in the locking position, the signal assembly 40 sends a locking success signal to the controller, and the controller controls the electromagnet to be powered off. When the supporting portion 31 and the locking member 20 are separated from each other, the signal switch sends an unlocking success signal to the controller, the locking member 20 rotates to the unlocking position, and the controller controls the member to be locked 200 to be away from the locking member 20. Thus, through the control of the signal component 40 and the controller, the automatic control is completely realized, and the manual participation is avoided.
Further, the signal assembly 40 includes a pulling piece 41 and a switch piece 42, the transmission piece 322 is connected with the pulling piece 41, and the switch piece 42 includes a locking micro switch 421 and an unlocking micro switch 422. When the transmission member 322 moves toward the end far from the locking member 20, the pulling piece 41 moves synchronously with the transmission member 322 and contacts with the unlocking micro switch 422 to send out an unlocking success signal. When the transmission member 322 moves between the locking member 20 and the bottom wall of the mounting groove 11, the pulling piece 41 moves synchronously with the transmission member 322 and contacts the locking micro switch 421 to signal that the locking is successful.
Specifically, when the locking device 100 provided by the application is in a locking state, if a special fault occurs, the electromagnet is abnormally operated, and the locking device can be unlocked manually, and the supporting part 31 is driven to move to a side far away from the locking part 20 by pushing the limiting part 50 to move in the sliding groove 12, so that the function of the electromagnet is replaced, and the convenience in disassembly is realized.
The specific matching process of the locking device 100 and the to-be-locked piece 200 provided by the application is as follows:
And (3) locking: the to-be-locked piece 200 moves from the far position along the Y positive direction towards the locking piece 20, and when the to-be-locked piece 200 contacts with the locking piece 20, the to-be-locked piece 200 pushes the locking piece 20 to rotate upwards until the to-be-locked piece is horizontal; at this time, the to-be-locked member 200 is engaged with the locking groove 22 of the locking member 20; meanwhile, the supporting portion 31 is pushed to the lower portion of the locking piece 20 by the elastic restoring force of the elastic piece, and the limiting piece 50 moves to the first limit position in the sliding groove 12 along with the supporting portion 31, so that limiting of the supporting portion 31 is achieved. At this time, the pulling piece 41 contacts with the locking micro switch 421, and the locking micro switch 421 sends a locking success signal to the controller. At this time, the to-be-locked member 200 realizes the limit locking in the Y direction, and this state is the locking state, and the whole locking process is completed in the power-off state.
And (3) unlocking: when the locking device 100 is in the locked state, the power source 3211 is operated, for example, the electromagnet is energized, and at this time, the transmission member 322 compresses the elastic member and moves to a side far away from the locking member 20 under the electromagnetic force, and drives the supporting portion 31 to move out from the lower portion of the locking member 20. Meanwhile, the driving piece 322 pushes the pulling piece 41 to move backwards along the reverse direction of Y, the pulling piece 41 is in contact with the unlocking micro switch 422, the unlocking micro switch 422 sends out an unlocking success signal, when the controller receives the unlocking success signal, the piece 200 to be locked can be moved away from the locking piece 20 along the reverse direction of Y at the moment so as to be separated from the locking groove 22, and the unlocking process is finished at the moment, and the state is the unlocking state.
Further, when the to-be-locked member 200 is separated from the locking member 20, the rotating end 23 of the locking member 20 is under the action of gravity and is located at the bottom of the mounting groove 11, the electromagnet can be powered off at this time, the driving member 322 is under the action of the elastic force of the elastic member to push the supporting portion 31 to move forward along Y until the supporting portion 31 just contacts with the rotating end 23, and at this time, the pulling piece 41 is not contacted with the locking micro switch 421 and the unlocking micro switch 422, which is a transition state, so that the locking device 100 can be conveniently switched to the locking state.
