As shown in fig. 1 to 15, the present invention provides a lock body, which comprises a driving member 8, a transmission mechanism 10 and a lock pin 6; the driving part 8 is connected with the lock pin 6 through a transmission mechanism 10 and is used for driving the lock pin 6 to do axial reciprocating motion of extending and retracting.
In this embodiment, the lock body provides the power for moving the lock pin 6 through the driving member 8, and the driving force of the driving member 8 is transmitted to the lock pin 6 through the transmission mechanism 10, so as to drive the lock pin 6 to make axial reciprocating motion in the lock hole 3, thereby realizing the connection locking and separation unlocking between the lock body and the lock ring.
In this embodiment, the driving member 8 is used as the power source of the lock body, but it is not limited to the driving member 8, and it may be other power devices, such as a manual driving device using a handle, etc., as long as the power source for inserting and sliding the lock pin 6 into and out of the lock hole 3 is provided.
In the present embodiment, the lock pin 6 is embodied as a cylindrical rod-shaped structure.
It should be noted that the lock pin 6 may be a cylindrical rod-shaped structure, but it is not limited to the above-mentioned one, and it may also be a square column, a triangular prism, a hexagonal prism, etc. as long as it can cooperate with the lock hole 3 on the locking ring to achieve the locking function.
In this embodiment, the vehicle lock body 1 further includes an outer case; the driving piece 8 and the transmission mechanism 10 are arranged in the outer shell; the outer shell is provided with a pin hole for the lock pin 6 to pass through.
Through the setting of casing for all spare parts can both be placed in the shell body on the lock body 1, protect each spare part through the shell body, and then guaranteed the life of each spare part, also avoided the influence that external environment caused each spare part in the lock body 1 simultaneously, improved the stability that lockpin 6 removed.
In the present embodiment, the transmission mechanism 10 can be disposed in various ways, specifically, the following ways are provided:
in a first arrangement of the transmission mechanism 10, as shown in fig. 2-8, the transmission mechanism 10 includes a transmission wheel 13, a projection 16 and a first linkage 14; the first linkage portion 14 is provided on the lock pin 6; the transmission rotating wheel 13 is arranged on the driving piece 8; the protruding portion 16 is disposed on a side of the transmission wheel 13 away from the driving member 8, and abuts against a side of the first linkage portion 14 close to the lock pin 6, so as to drive the lock pin 6 to slide out of the lock hole 3 under the action of the driving member 8.
In the present embodiment, the transmission mechanism 10 is coaxially connected to the motor shaft of the driving member 8 by using the transmission runner 13, and can be rotated by the driving member 8.
The protruding portion 16 is disposed on one side of the transmission runner 13 away from the driving member 8, and the rotation of the transmission runner 13 drives the protruding portion 16 to rotate around the central axis 38 of the transmission runner 13, so as to drive the first linkage portion 14 to move in a direction away from or close to the lock hole 3 through the protruding portion 16, and further drive the lock pin 6 to be drawn out of the lock hole 3, or drive the lock pin 6 to be inserted into the lock hole 3.
In the present embodiment, the protruding portion 16 has a columnar structure, and a flat surface capable of being attached to the first interlocking portion 14 is provided on a side wall thereof.
In the present embodiment, the first interlocking part 14 is fixedly provided on the locking pin, and the fixing manner is an integral setting or a fixing connection manner such as caulking, welding, and the like.
In the present embodiment, the first linkage portion 14 has a plate-like structure.
Further, a stopping portion 15 is disposed on the first linkage portion 14, and one side of the stopping portion 15 abuts against the protruding portion 16 for preventing the transmission runner 13 from rotating.
As shown in fig. 3 and 8, when the driving member 8 drives the transmission wheel 13 to rotate clockwise, the stopping portion 15 disposed on the first linking portion 14 stops the protruding portion 16, so as to prevent the transmission wheel 13 from rotating, and thus the rotation positioning of the transmission wheel 13 is realized.
In the present embodiment, the blocking portion 15 and the first linkage portion 14 are integrally provided, specifically, are provided in an L-shaped plate structure. When the protrusion 16 needs to be blocked counterclockwise, the blocking portion 15 may be provided at the other end of the first linkage portion 14.
In a second arrangement of the transmission mechanism 10, the transmission mechanism 10 includes a transmission cam and a second linkage; the second linkage part is fixedly arranged on the lock pin 6; the transmission cam is arranged on the driving piece 8, and the side wall of the transmission cam is abutted against one side, close to the lock pin 6, of the second linkage part, and is used for driving the lock pin 6 to slide out of the lock hole 3 under the action of the driving piece 8.
In this embodiment, a driving cam is used to apply a pushing force to the second coupling portion, so as to move the second coupling portion, and further to drive the lock pin 6 to be inserted into the lock hole 3, or to drive the lock pin 6 to be withdrawn from the lock hole 3. That is, the second linkage portion is pushed by the distance difference formed when the transmission cam rotates, and the lock pin 6 is further moved.
Further, the lock pin 6 is provided with a reset means for withdrawing the lock pin 6 from the lock hole 3 or inserting the lock pin 6 into the lock hole 3, as shown in fig. 6.
By means of the resetting device, a force can be always applied to the lock pin 6, and the direction of the force is opposite to the direction of the force applied by the protrusion 16 to the first linkage portion 14, so that the protrusion 16 and the resetting device respectively drive the lock pin 6 to be drawn out of the lock hole 3 and drive the lock pin 6 to be inserted into the lock hole 3.
When the lock is used, the driving part 8 drives the lock pin 6 to be drawn out of the lock hole 3, the lock pin 6 cannot be driven to be inserted into the lock hole 3, and therefore the safety of the lock pin 6, the transmission mechanism 10 and the driving part 8 is guaranteed under the condition that the lock hole 3 is not aligned with the lock pin 6.
When the lock pin 6 needs to be inserted into the lock hole 3, the driving member 8 stops supplying power to the transmission mechanism 10, so that the lock pin 6 no longer has power to be drawn out of the lock hole 3, and the lock pin 6 is inserted into the lock hole 3 under the action of the resetting device. When the lock hole 3 is not corresponding to the lock pin 6, the lock pin 6 is abutted against the locking part 2 under the action of the reset device, and when the wheel rotates, after the lock hole 3 is corresponding to the lock pin 6, the lock pin 6 enters the lock hole 3 under the action of the reset device, so that the vehicle locking function is realized.
The reset device has many setting modes, and specifically, the following setting modes can be provided:
in a first setting of the resetting device, the resetting device is a first pressure spring 19; one end of the first pressure spring 19 is fixed on the outer shell, and the other end of the first pressure spring is pressed against the lock pin 6.
Through carrying out the butt with the lockpin 6 with the one end of first pressure spring 19, after the other end is fixed to be set up on the shell, can realize giving lockpin 6 one and take out or insert the power in lockhole 3 from lockhole 3, and then make driving piece 8 through the back of 16 taking lockpin 6 out from lockhole 3, after drive power disappears, can be under resetting means's effect, in the lockhole 3 is inserted once more to accomplish the operation of locking the car.
It should be noted that one end of the first pressure spring 19 abuts against the lock pin 6, and the other end may be fixedly connected to the outer housing, or may be directly fixedly connected to the vehicle frame, that is, the other end of the first pressure spring 19 may be fixed to the vehicle frame.
