A lock body structure 100 according to an embodiment of the present utility model is described below with reference to fig. 1-8.

As shown in fig. 1, a lock body structure 100 according to an embodiment of the present utility model includes: a lock body assembly 1 and a lock pin assembly 2.

Specifically, as shown in fig. 2 to 8, the lock body assembly 1 includes a mounting main load bearing structure 11, a displacement sleeve structure 12, and a stopper 13. The installation main bearing structure 11 includes a lock body 111 and a lock body installation plate 112, the lock body 111 has a locking hole 1111, and two axial ends of the locking hole 1111 are a first end 1113 and a second end 1114, respectively. The locking hole 1111 has a limiting hole 1112 on a peripheral wall, and the limiting hole 1112 penetrates through the peripheral wall of the lock body 111.

As shown in fig. 5, the lock body mounting plate 112 is connected to the outer peripheral wall of the lock body 111 and extends in the circumferential direction of the lock body 111 into a ring shape, and the displacement sleeve structure 12 is sleeved outside the lock body 111 and is located at one axial side of the lock body mounting plate 112. The displacement sleeve structure 12 is movable along the axial direction of the locking hole 1111, the limiting member 13 is arranged through the limiting hole 1112 and is positioned at the inner side of the displacement sleeve structure 12, the limiting member 13 is movable along the axial direction of the limiting hole 1112, and the displacement sleeve structure 12 is configured to drive the limiting member 13 to move towards the locking hole 1111 when moving in the direction from the first end 1113 to the second end 1114.

As shown in fig. 5, the lock pin assembly 2 includes a lock pin body 21, a second end 1114 of the lock pin body 21, which is detachably disposed in the locking hole 1111, and a limit groove 211, which is matched with the limit piece 13, is disposed on an outer peripheral wall of the lock pin body 21. When the limiting piece 13 is matched with the limiting groove 211, the locking pin body 21 can be limited to move in the locking hole 1111 along the axial direction of the locking hole 1111, so that the locking of the lock body structure 100 is realized by fixedly connecting the locking pin assembly 2 with the lock body assembly 1, and when the limiting piece 13 is disengaged from the limiting groove 211, the locking pin body 21 can move freely in the locking hole 1111 along the axial direction of the locking hole 1111, so that the locking pin body 21 can be detached from the locking hole 1111, and the unlocking of the locking pin assembly 2 and the lock body assembly 1 is realized.

In practical application, the lock pin assembly 2 can be connected with a fixed part such as a vehicle body, the lock body assembly 1 can be connected with a fixed part such as a battery pack, and the battery pack can be fixed and separated from the vehicle body through locking and unlocking of the lock pin assembly 2 and the lock body assembly 1.

When the lock pin assembly 2 and the lock body assembly 1 are connected, the lock pin body 21 of the lock pin assembly 2 can be inserted into the locking hole 1111 of the installation main bearing structure 11 of the lock body assembly 1, when the limiting groove 211 is opposite to the limiting hole 1112, the displacement sleeve structure 12 can be driven to move from the first end 1113 to the second end 1114 along the axial direction of the locking hole 1111, so that the limiting piece 13 is pushed to move towards the locking hole 1111 along the axial direction of the limiting hole 1112, and part of the limiting piece 13 moves into the limiting groove 211 to be matched with the limiting groove 211, so that the movement of the lock pin body 21 in the axial direction of the locking hole 1111 is limited, and the lock pin assembly 2 and the lock body assembly 1 are locked.

When the lock pin assembly 2 and the lock body assembly 1 are unlocked, the displacement sleeve structure 12 moves from the second end 1114 to the first end 1113 along the axial direction of the locking hole 1111, the driving action on the limiting piece 13 is released, the limiting piece 13 can move along the limiting hole 1112 towards the direction away from the locking hole 1111 under the action of the pushing force when the lock pin body 21 moves along the locking hole 1111, so that the limiting piece 13 is separated from the limiting groove 211, the limitation of the lock pin body 21 in the axial direction of the locking hole 1111 is released, the lock pin body 21 can be pulled out from the locking hole 1111, and the lock pin assembly 2 and the lock body assembly 1 are unlocked.

When the lock pin assembly 2 is connected with the fixing piece, the lock pin assembly can be directly connected with the fixing piece through the lock pin body 21, and the lock pin body 21 can be indirectly connected with the fixing piece through other intermediate connecting pieces; when the lock body assembly 1 is connected with the fixed piece, the lock body assembly 1 can be connected with the fixed piece through the lock body mounting plate 112, so that the lock body assembly 1 is connected with the fixed piece.

Of course, the present utility model is not limited thereto, and the lock body assembly 1 may be connected to the fixed member, and the lock pin assembly 2 may be connected to the fixed member, without limitation.

Alternatively, the limit groove 211 extends as an annular groove in the circumferential direction of the latch body 21, whereby the flexibility of the engagement between the limit groove 211 and the stopper 13 can be increased, so that the angle at which the latch body 21 is inserted into the locking hole 1111 is not limited, and the engagement with the stopper 13 can be achieved.

According to the lock body structure 100 of the embodiment of the utility model, the lock body 111 provided with the main bearing structure 11 is provided with the locking hole 1111, the peripheral wall of the locking hole 1111 is provided with the limit hole 1112, the limit piece 13 is penetrated into the limit hole 1112, the lock pin body 21 is detachably arranged in the locking hole 1111, the peripheral wall of the lock pin body 21 is provided with the limit groove 211, and the lock body 111 is sleeved with the displacement sleeve structure 12. When the displacement sleeve structure 12 moves from the first end 1113 to the second end 1114 in the axial direction of the locking hole 1111, the limiting member 13 is driven to move to the locking hole 1111 and cooperate with the limiting groove 211 to limit the axial displacement of the lock pin body 21, so as to complete the locking process; when the lock body structure 100 is unlocked, the displacement sleeve structure 12 is moved reversely, the driving of the displacement sleeve structure 12 to the limiting piece 13 is released, the limiting piece 13 is separated from the limiting groove 211 under the action of the driving force of the locking pin body 21 moving along the axial direction of the locking hole 1111, the locking pin body 21 is detachable from the locking hole 1111, the unlocking of the locking pin assembly 2 and the lock body assembly 1 is realized, the lock body structure 100 is simple, and the locking and unlocking processes are simple and easy to operate.

In some embodiments of the present utility model, the stop 13 is a ball as shown in fig. 5, 7 and 8. The ball-shaped structure enables the limiting member 13 to enter or exit the limiting groove 211 more quickly and effectively in the locking and unlocking process, so that the locking and unlocking process of the lock body structure 100 is more reliable. In addition, the ball-shaped limiting piece 13 is not limited by the angle of the limiting piece 13 when being matched with the limiting groove 211, and the limiting piece 13 can rotate arbitrarily.

Further, as shown in fig. 7, an end of the inner circumferential wall of the limiting hole 1112 near the locking hole 1111 is a spherical surface, and an aperture of an end of the limiting hole 1112 near the locking hole 1111 is smaller than a diameter of the ball. When the end of the inner peripheral wall of the limit hole 1112, which is close to the locking hole 1111, is a spherical surface, the movement towards the limit groove 211 during locking and the extrusion of the limit groove 211 during unlocking of the ball are facilitated. In the unlocking state, the lock pin assembly 2 is separated from the lock body assembly 1, the diameter of one end of the limiting hole 1112, which is close to the locking hole 1111, should be smaller than the diameter of the ball, so that the ball is prevented from rolling into the locking hole 1111, the reliability of fixing the ball in the limiting hole 1112 is ensured, the assembly efficiency is effectively prevented from being influenced due to falling of the ball, the cost increase caused by the loss of the ball is avoided, and meanwhile, the potential safety hazard that the lock body structure 100 cannot be locked due to the fact that the limiting piece 13 is missing of the ball is avoided.

In addition, as shown in fig. 5 and 7, the end of the limiting hole 1112 away from the locking hole 1111 has a constant aperture in the axial direction of the limiting hole 1112, and the end of the limiting hole 1112 away from the locking hole 1111 has an aperture equal to or larger than the diameter of the ball, thereby facilitating the assembly of the ball from the end of the limiting hole 1112 away from the locking hole 1111.

In some embodiments of the present utility model, as shown in fig. 5 and 7, the displacement sleeve structure 12 has an unlocking groove 121 on an inner peripheral wall, and a side wall of the unlocking groove 121 near the first end 1113 is inclined away from the locking hole 1111 in a direction from the first end 1113 to the second end 1114, and when the stopper 13 is opposite to the unlocking groove 121, the stopper 13 may move toward the unlocking groove 121 to disengage the stopper 13 from the stopper groove 211. It will be appreciated that the inner diameter of the displacement sleeve structure 12 at the bottom wall of the unlocking slot 121 is greater than the inner diameter of the region of the displacement sleeve structure 12 where the unlocking slot 121 is not provided.

During the locking process of the locking pin assembly 2 and the locking body assembly 1, the locking pin body 21 is inserted into the locking hole 1111, the limiting groove 211 on the locking pin body 21 is opposite to the limiting hole 1112 on the peripheral wall of the locking hole 1111, the displacement sleeve structure 12 moves from the first end 1113 to the second end 1114 along the axial direction of the locking hole 1111, the side wall, close to the first end 1113, of the unlocking groove 121 is in contact with the limiting piece 13, the limiting piece 13 is driven to move towards the locking hole 1111 until the area, outside the unlocking groove 121, of the displacement sleeve structure 12 is opposite to the limiting piece 13, the fixing of the limiting piece 13 is achieved, at the moment, part of the limiting piece 13 is located in the limiting groove 211, and the locking pin body 21 is limited to move in the axial direction in the locking hole 1111.

During unlocking of the lock pin assembly 2 and the lock body assembly 1, the displacement sleeve structure 12 is moved reversely, that is, the displacement sleeve structure 12 is moved from the second end 1114 to the first end 1113 along the axial direction of the locking hole 1111, the unlocking slot 121 is gradually opposite to the limiting hole 1112, so that space is provided for the limiting piece 13 to move away from the outside of the locking hole 1111, when the unlocking slot 121 is completely opposite to the limiting hole 1112, a part of the limiting piece 13 can be located in the unlocking slot 121, so that the limiting piece 13 can be disengaged from the limiting slot 211, and the lock pin body 21 can be freely moved in the axial direction of the locking hole 1111 and pulled out from the locking hole 1111.

When the unlocking groove 121 is opposite to the limiting hole 1112, the locking pin body 21 can be pulled to drive the limiting piece 13 to move towards the unlocking groove 121, so that the limiting piece 13 is separated from the limiting groove 211.

Alternatively, both side walls of the stopper groove 211 in the axial direction of the lock pin body 21 are inclined in a direction away from each other in a direction away from the axis of the lock pin body 21, thereby facilitating the movement of the driving stopper 13 in a direction away from the locking hole 1111 while also facilitating the alignment of the stopper 13 with the stopper groove 211 during locking.

In some embodiments of the present utility model, the displacement sleeve structure 12 is threadably coupled to the lock body 111. This can be converted into a movement of the displacement sleeve structure 12 in the axial direction of the lock body 111 by a rotational movement between the displacement sleeve structure 12 and the lock body 111. Wherein the displacement sleeve structure 12 may be driven in rotation by an external structure, such as an external power station rotation mechanism, thereby effecting movement of the displacement sleeve structure 12 in the axial direction of the lock body 111.

The unlocking groove 121 is an annular groove extending along the circumferential direction of the displacement sleeve structure 12, so that the displacement sleeve structure 12 can ensure the matching relationship between the unlocking groove 121 and the limiting piece 13 in the rotating process.

When the displacement sleeve structure 12 is driven to rotate positively by the external structure, the displacement sleeve structure 12 moves from the first end 1113 to the second end 1114 along the axial direction of the locking hole 1111, the side wall, close to the first end 1113, of the unlocking groove 121 contacts with the limiting piece 13, and drives the limiting piece 13 to move towards the locking hole 1111 until the displacement sleeve structure 12 is located in a region outside the unlocking groove 121 and is opposite to the limiting piece 13, so that the limiting piece 13 is fixed, at the moment, part of the limiting piece 13 is located in the limiting groove 211, and the locking pin body 21 is limited to move in the axial direction in the locking hole 1111, so that the locking process is completed; when the displacement sleeve structure 12 is driven to reversely rotate by the external structure, the displacement sleeve structure 12 moves from the second end 1114 to the first end 1113 along the axial direction of the locking hole 1111, the unlocking groove 121 is gradually opposite to the limiting hole 1112, so that space is provided for the limiting piece 13 to move away from the outside of the locking hole 1111, when the unlocking groove 121 is completely opposite to the limiting hole 1112, part of the limiting piece 13 can be positioned in the unlocking groove 121, so that the disengagement of the limiting piece 13 and the limiting groove 211 can be realized, and the lock pin body 21 can freely move in the axial direction of the locking hole 1111 and be pulled out from the locking hole 1111, so that the unlocking process is completed.

In some embodiments of the utility model, as shown in fig. 4 and 6, the lock body mounting plate 112 is located at an axial end of the lock body 111 near the second end 1114. In this position, the lock body mounting plate 112 is in proximity to the lock pin assembly 2, facilitating the cooperation of the lock body assembly 1 with the lock pin assembly 2 after installation, and making the locking and unlocking process more reliable.

In some embodiments of the present utility model, as shown in fig. 5 and 7, the lock body assembly 1 further includes: the limiting protective sleeve 14 is sleeved outside the displacement sleeve structure 12 and is spaced apart from the displacement sleeve structure 12, and one axial end of the limiting protective sleeve 14 is connected with the lock body mounting plate 112. Because the working environment of the lock body structure 100 is complex, in order to prevent the pollution inside the lock body, the limit protective sleeve 14 is additionally arranged outside the main working part of the lock body assembly 1, so that a relatively airtight and clean working space can be created for the lock body structure 100, and the lock body structure 100 is prevented from being invalid.
