Description

Technical Field

[0001] The present invention relates to a lock, and particularly to a push-type lock for a battery pack of an electric product. Background Art

[0002] Electric products are equipped with battery packs. According to the existing technology, the battery pack is installed on the product in a snap-fit manner and is electrically connected to the power-consuming device in the product. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a push-type lock structure to facilitate the connection and disassembly of the battery pack and the electric product.

[0004] To solve the above technical problem, the present invention provides the following technical solution: a push-type lock structure, including a movable lock block and a fixed lock block, and an elastic member used in cooperation with the movable lock block; a track groove and a lock pin for cooperative use are provided between the movable lock block and the fixed lock block; the movable lock block is provided with a lock head; the fixed lock block is hinged on a fixed block, a locking step is provided beside the lock head, and the locked member is provided with a lock groove cooperating with the lock head; the forward and backward movement of the locked member can drive the movable lock block to move forward and backward, so that the lock pin makes a one-way clockwise / counterclockwise movement along the track groove, and the backward movement of the movable lock block makes the lock head abut against the locking step; a convex head is provided on the fixed block, a groove is provided on the fixed lock block, the groove is far from the hinge axis of the fixed lock block and the fixed block and close to the lock pin, the convex head cooperates with the groove, and there is a left-right gap between the convex head and the groove.

[0005] As an option, the track groove is provided on the movable lock block, and the lock pin is provided on the fixed lock block.

[0006] According to the above technical solution, the operator drives the locked member forward and backward, the locked member drives the movable lock block, and the lock pin of the fixed lock block makes a one-way clockwise / counterclockwise movement in the track groove. When the lock pin moves to the locking groove of the track groove, the operator releases the locked member. Under the action of the elastic force of the elastic member, the lock pin stays in the locking groove, the position of the movable lock block is locked, and at this time, the movable lock block is in the locked position, the lock head abuts against the locking step, the lock head is restricted in the lock groove of the locked member, the lock head locks the locked member, and the locked member cannot be separated from the movable lock block.

[0007] When unlocking, the operator drives the locked member forward and backward and then releases it, so that the lock pin of the fixed lock block makes a one-way clockwise / counterclockwise movement in the track groove. Under the action of the elastic member, the lock pin disengages from the locking groove and moves to the unlocking groove of the track groove. At this time, the movable lock block is in the unlocked position, the lock head leaves the locking step, and the operator can pull the locked member to make the lock head disengage from the lock groove, and then the locked member is separated from the movable lock block.

[0008] To ensure that the locking pin on the fixed locking block makes a one-way clockwise / counterclockwise movement in the track groove of the movable locking block, the present invention designs a convex head and a groove, and there is a left-right gap between the two. This gap causes the locking pin to have a one-way yaw under the limitation of the track groove. This yaw enables the locking pin not to retreat to the just-passed track, but to continue to make a one-way clockwise / counterclockwise movement along the track groove. Especially when unlocking, the operator drives the locked part back and forth and then releases it, causing the locking pin of the fixed locking block to have a one-way yaw. This yaw makes the locking pin not retreat into the locking groove, but continue to make a one-way clockwise / counterclockwise movement along the track groove. Under the action of the elastic member, the locking pin can smoothly move to the unlocking groove of the track groove.

[0009] As an option, the elastic member is a spring.

[0010] As an improvement, the convex head is conical / trapezoidal, and correspondingly, the groove is conical / trapezoidal. When the locking pin makes a one-way clockwise / counterclockwise movement along the track groove, the fixed locking block yaws left and right. Suppose the locking pin enters the locking groove from the unlocking groove, first yawing to the left and then to the right; the locking pin enters the unlocking groove from the locking groove, first yawing to the right and then to the left. Then, during the process of the locking pin entering the locking groove from the unlocking groove, the left side wall of the convex head abuts against the left side wall of the groove, and the two slide relative to each other, accumulating elastic potential energy. When the locking pin enters the locking groove, the elastic potential energy is released, the fixed locking block swings to the right, and the locking pin follows and enters the unlocking groove. During the process of the locking pin entering the unlocking groove from the locking groove, since there is a gap between the right side wall of the convex head and the right side wall of the groove, therefore, under the action of the track groove, the fixed locking block swings to the right, and the locking pin follows, and can smoothly make a one-way clockwise / counterclockwise movement and enter the unlocking groove.

[0011] The fixed block is installed in a housing member, and the locking step is provided on the inner side wall of the housing member. The movable locking block and the fixed locking block are both located in the housing member.

[0012] The outer side wall of the movable locking block is provided with a guiding groove, the locking step is movably fitted in the guiding groove, and the inner side wall of the movable locking block is fitted with the limiting plane of the fixed block. Under the combined action of the guiding groove and the limiting plane, the movable locking block is limited left and right and can only displace back and forth along the locking step.

[0013] As an option, the fixed locking block is in a clamp shape, the fixed locking block is provided with a pair of locking pins, the pair of locking pins are arranged up and down relatively, and the upper and lower surfaces of the movable locking block are both provided with track grooves, and the pair of locking pins are fitted with the track grooves on the upper and lower surfaces of the movable locking block in a one-to-one manner.

[0014] The tail of the movable lock block is provided with a first elastic member hole, and the tail of the fixed lock block is provided with a second elastic member hole. The front end of the elastic member is fitted in the first elastic member hole, and the tail end of the elastic member passes through the second elastic member hole and abuts against the inner bottom of the housing member. Since the elastic member passes through the second elastic member hole, the elastic member has a reset function for the left and right swing of the fixed lock block. When the fixed lock block swings left and right with too large an amplitude around the hinge axis, the elastic member can reset it so that the convex head and the groove are re-fitted.

[0015] The movable lock block is provided with a front end face that abuts against the locked member. The lock head is located on the side of the movable lock block and protrudes forward from the front end face. The locked member drives the movable lock block to displace back and forth by abutting against the front end face of the movable lock block.

[0016] The present invention provides a push-type lock structure. The locked member can be a battery pack, and the housing member is fixedly arranged on an electric product. Thus, by pressing the battery pack, it can be conveniently connected to or disconnected from the electric product. Description of the Drawings

[0031] Combined with Figure 1 and Figure 3 , a push - type lock structure includes a movable lock block 10, a fixed lock block 20, and an elastic member 30 used in cooperation with the movable lock block. The movable lock block is provided with a track groove 11 and a lock head 12, the fixed lock block is provided with a lock pin 21, the lock pin is fitted in the track groove, the fixed lock block is hinged to a fixed block 40, a locking step 51 is provided beside the lock head, and the locked part 60 is provided with a lock groove 61 that cooperates with the lock head. The forward and backward movement of the locked part can drive the movable lock block to move forward and backward, so that the lock pin moves in a one - way clockwise / counter - clockwise manner along the track groove, and the backward movement of the movable lock block makes the lock head abut against the locking step.

[0032] Refer to Figure 1 and Figure 6 , the fixed block 40 is provided with a convex head 41, the fixed lock block 20 is provided with a groove 22, the groove is far from the hinge axis 23 of the fixed lock block and the fixed block and close to the lock pin, the convex head cooperates with the groove, and there is a left - right gap between the convex head and the groove.

[0033] The convex head 41 is conical / trapezoidal, and correspondingly, the groove 22 is conical / trapezoidal.

[0034] Refer to Figure 1 and Figure 2 , the fixed block 40 is installed in a housing part 50, and the locking step 51 is arranged on the inner side wall of the housing part.

[0035] As Figure 3 , the outer side wall of the movable lock block 10 is provided with a guide groove 13, the locking step 51 is movably fitted in the guide groove, and the inner side wall of the movable lock block cooperates with the limiting plane 42 of the fixed block.

[0036] Combined with Figure 3 and Figure 5 , the fixed lock block 20 is in a pincer shape, the fixed lock block is provided with a pair of lock pins 21, the pair of lock pins are arranged up and down relatively, and the upper and lower surfaces of the movable lock block 10 are both provided with track grooves 11, and the pair of lock pins cooperate with the track grooves on the upper and lower surfaces of the movable lock block in a one - to - one manner.

[0037] As Figure 4, a first elastic member hole 14 is provided at the tail of the movable locking block 10, a second elastic member hole 24 is provided at the tail of the fixed locking block 20, the front end of the elastic member 30 is fitted in the first elastic member hole, and the tail end of the elastic member passes through the second elastic member hole and abuts against the inner bottom of the housing member 50.

[0038] As Figure 3 , the movable locking block 10 is provided with a front end face that abuts against the locked member 60, and the lock head 12 is located at the side of the movable locking block and protrudes forward from the front end face.

[0039] The locked member 60 is a battery pack, or a battery pack is accommodated therein, and the housing member 50 is fixedly arranged on an electric product. The operator presses the locked member 60, and the locked member moves forward and backward. The locked member drives the movable locking block 10, and the locking pin 21 of the fixed locking block makes a one-way clockwise / counterclockwise movement in the track groove 11. When the locking pin 21 moves to the locking groove 111 of the track groove, the operator releases the locked member 60. Under the action of the elastic force of the elastic member 30, the locking pin stays in the locking groove, the position of the movable locking block 10 is locked, and at this time, the movable locking block is in the locked position. The lock head 12 abuts against the locking step 51, and the lock head is restricted in the locking groove 61 of the locked member, and the lock head locks the locked member, and the locked member cannot be separated from the movable locking block.

[0040] When unlocking, the operator presses the unlocking member 60, drives the locked member forward and backward and then releases it, so that the locking pin 21 of the fixed locking block 20 makes a one-way clockwise / counterclockwise movement in the track groove 11. Under the action of the elastic member 30, the locking pin disengages from the locking groove 111 and moves to the unlocking groove 112 of the track groove. At this time, the movable locking block 10 is in the unlocked position, the lock head 12 leaves the locking step 51, and the operator can pull the locked member 60 to make the lock head 12 disengage from the locking groove 61, and then the locked member is separated from the movable locking block.

[0041] In order to ensure that the locking pin 21 on the fixed locking block 20 makes a one-way clockwise / counterclockwise movement in the track groove 11 of the movable locking block, the present invention designs a convex head 41 and a groove 22, and there is a left-right gap between the two. This gap causes the locking pin 21 to make a one-way yaw under the limitation of the track groove 11. This yaw enables the locking pin not to retreat to the just-passed track, but to continue to make a one-way clockwise / counterclockwise movement along the track groove 11. Especially when unlocking, the operator drives the locked member 60 forward and backward and then releases it, causing the locking pin 21 of the fixed locking block to make a one-way yaw. This yaw makes the locking pin not retreat into the locking groove 111, but continue to make a one-way clockwise / counterclockwise movement along the track groove 11. Under the action of the elastic member 30, the locking pin 21 can smoothly move to the unlocking groove 112 of the track groove.

[0042] When the locking pin 21 moves unidirectionally clockwise / counterclockwise along the track groove 11, the fixed locking block 20 swings left and right. Suppose the locking pin 21 enters the locking groove 111 from the unlocking groove 112, first swings left and then right; when the locking pin enters the unlocking groove 111 from the locking groove 112, it first swings right and then left. Then, during the process of the locking pin 21 entering the locking groove 111 from the unlocking groove 112, the left side wall of the convex head 41 abuts against the left side wall of the groove 22, and relative sliding occurs between the two, accumulating elastic potential energy. When the locking pin 21 enters the locking groove 111, the elastic potential energy is released, the fixed locking block 20 swings to the right, and the locking pin 21 follows and enters the unlocking groove 111. During the process of the locking pin entering the unlocking groove 112 from the locking groove 111, since there is a gap between the right side wall of the convex head 41 and the right side wall of the groove 22, therefore, under the action of the track groove 11, the fixed locking block 20 swings to the right, and the locking pin 21 follows, and can smoothly move unidirectionally clockwise / counterclockwise and enter the unlocking groove 112.
