Description

Technical Field

[0001] This utility model relates to a locking and unlocking structure. Background Technology

[0002] The locking and unlocking of accessories and the main body of the product require corresponding locking and unlocking structures. For example, electric products are equipped with a battery pack. The battery pack is installed on the main body of the product, which is the locking of the accessory; the battery pack is removed from the main body of the product, which is the unlocking of the accessory. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a press-to-unlock structure to facilitate the locking and unlocking of accessories and the main body of the product, especially the connection and disassembly of battery packs and electric products.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a press-to-unlock structure, including a movable locking block and a fixed locking block, and an elastic element used in conjunction with the movable locking block; a track groove and a locking pin are provided between the movable locking block and the fixed locking block for cooperation; the movable locking block is provided with a lock head (12); the fixed locking block is hinged to the fixed block, and a locking step is provided on the side of the lock head, and the locked part is provided with a locking groove that cooperates with the lock head; the forward and backward movement of the locked part can drive the movable locking block to move forward and backward, so that the locking pin moves unidirectionally clockwise / counterclockwise along the track groove, and the backward movement of the movable locking block causes the lock head to abut against the locking step; the locking step is provided on the inner side wall of the housing part, the fixed block is installed inside the housing part, and the locking groove is provided on the accessory.

[0005] Alternatively, the track groove is disposed on the movable locking block, and the locking pin is disposed on the fixed locking block.

[0006] According to the above technical solution, the operator presses the accessory (the locked part), causing the accessory to move back and forth, driving the movable locking block. The locking pin of the fixed locking block moves unidirectionally clockwise / counterclockwise in the track groove. When the locking pin moves to the locking groove of the track groove, the operator releases the accessory. Under the action of the elastic force of the elastic element, the locking pin stays in the locking groove, and the position of the movable locking block is locked. At this time, the movable locking block is in the locked position, and the lock head abuts against the locking step. The lock head is restricted in the locking groove of the accessory, and the lock head locks the accessory. The accessory cannot detach from the movable locking block and is locked in the housing.

[0007] When unlocking, the operator presses the accessory and then releases it. The accessory moves back and forth, causing the locking pin of the fixed lock block to move unidirectionally clockwise / counterclockwise in the track groove. Under the action of the elastic element, the locking 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 one end of the accessory exits the housing. The operator can then pull the accessory out of the housing, and the lock head disengages from the lock groove.

[0008] Alternatively, the elastic element is a spring.

[0009] The mounting block is equipped with an electrical connection connector, and the accessory is equipped with an electrical connection socket, which mates with the connector. The housing connects to electric products, and the connector connects to the motor within the electric product. This connection is achieved through the mating of the connector and the socket.

[0010] The outer wall of the movable locking block is provided with a guide groove, and the locking step is movably fitted in the guide groove. The inner wall of the movable locking block is fitted with the limiting plane of the fixed block. Under the combined action of the guide groove and the limiting plane, the movable locking block is limited to the left and right, and can only move forward and backward along the locking step.

[0011] As an option, the movable locking blocks and the fixed locking blocks are in pairs, with the pair of fixed locking blocks distributed on the left and right sides of the fixed block, and the pair of movable locking blocks and the pair of fixed locking blocks cooperating in a one-to-one manner. The accessory is provided with a pair of locking grooves that cooperate with the pair of movable locking blocks.

[0012] As an alternative, the fixed locking block is clamp-shaped and has a pair of locking pins arranged opposite each other. The upper and lower surfaces of the movable locking block are provided with track grooves, and the pair of locking pins and the track grooves on the upper and lower surfaces of the movable locking block are matched one-to-one.

[0013] The movable locking block has a first elastic element hole at its tail, and the fixed locking block has a second elastic element hole at its tail. The front end of the elastic element fits into the first elastic element hole, and the tail end of the elastic element passes through the second elastic element hole, abutting against the inner bottom of the housing. Because the elastic element passes through the second elastic element hole, it has a reset function for the left and right swinging of the fixed locking block. When the fixed locking block swings excessively left and right around the hinge axis, the elastic element can reset it, allowing the protrusion to re-engage with the groove.

[0014] To ensure the locking pin on the fixed locking block moves unidirectionally clockwise / counterclockwise within the track groove of the movable locking block, this invention incorporates a protrusion and a groove. As an improvement, a lateral gap exists between these two elements. This gap allows the locking pin to oscillate unidirectionally within the track groove's limit. This oscillation prevents the locking pin from retracting into the previously traversed track, instead allowing it to continue moving unidirectionally clockwise / counterclockwise along the track groove. Especially during unlocking, when the operator drives the component forward and backward and then releases it, the locking pin on the fixed locking block oscillates unidirectionally. This oscillation prevents the locking pin from retracting into the locking groove, instead allowing it to continue moving unidirectionally clockwise / counterclockwise along the track groove. Under the action of the elastic element, the locking pin can smoothly move to the unlocking slot of the track groove.

[0015] As an improvement, the protrusion is conical / trapezoidal, and correspondingly, the groove is conical / trapezoidal. When the locking pin moves unidirectionally clockwise / counterclockwise along the track groove, the fixed locking block sways left and right. Assume that when the locking pin enters the locking groove from the unlocking groove, it first sways to the left and then to the right; when the locking pin enters the unlocking groove from the locking groove, it first sways 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 protrusion 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 sways to the right, and the locking pin follows, entering the unlocking groove. During the process of the locking pin entering the unlocking groove from the locking groove, because there is a gap between the right side wall of the protrusion and the right side wall of the groove, under the action of the track groove, the fixed locking block sways to the right, and the locking pin follows, enabling it to smoothly move unidirectionally clockwise / counterclockwise into the unlocking groove.

[0016] This utility model provides a press-to-unlock structure, in which the housing is fixedly mounted on an electric product, so that it can be easily connected to or disconnected from the electric product by pressing the accessory. Attached Figure Description

[0036] Combination Figure 1 , Figure 7 A press-to-unlock structure includes a movable locking block 10, a fixed locking block 20, and an elastic element 30 used in conjunction with the movable locking block. The movable locking block has a track groove 11 and a lock head 12, the fixed locking block has a locking pin 21, the locking pin engages in the track groove, the fixed locking block is hinged to a fixed block 40, a locking step 51 is provided on the side of the lock head, and the locked part has a locking groove 61 that engages with the lock head. The forward and backward movement of the locked part can drive the movable locking block to move forward and backward, causing the locking pin to move unidirectionally clockwise / counterclockwise along the track groove, and the backward movement of the movable locking block causes the lock head to abut against the locking step. The locking step 51 is provided on the inner side wall of the housing part 50, the fixed block 40 is installed inside the housing part, and the locking groove 61 is provided on the accessory 60.

[0037] Combination Figure 1 , Figure 2 The fixing block 40 is provided with an electrical connection plug 43, and the accessory 60 is provided with an electrical connection plug hole 62, which can cooperate with the electrical connection plug 43.

[0038] Combination Figure 4 , Figure 6 The outer side wall of the movable locking block 10 is provided with a guide groove 13, and the locking step 51 is movably fitted in the guide groove. The inner side wall of the movable locking block is fitted with the limiting plane 42 of the fixed block.

[0039] like Figure 1 The movable locking block 10 and the fixed locking block 20 are a pair. The pair of fixed locking blocks are distributed on the left and right sides of the fixed block 40. The pair of movable locking blocks and the pair of fixed locking blocks cooperate in a one-to-one manner. The accessory 60 is provided with a pair of locking grooves 61 that cooperate with the pair of movable locking blocks.

[0040] The fixed locking block 20 is clamp-shaped and has a pair of locking pins 21. The pair of locking pins are arranged opposite each other. The upper and lower surfaces of the movable locking block 10 are provided with track grooves 11. The pair of locking pins and the track grooves on the upper and lower surfaces of the movable locking block are matched one-to-one.

[0041] Combination Figure 1 , Figure 7 , Figure 8 The movable locking block 10 has a first elastic element hole 14 at its tail, and the fixed locking block 20 has a second elastic element hole 24 at its tail. The front end of the elastic element 30 fits in the first elastic element hole, and the tail end of the elastic element passes through the second elastic element hole and abuts against the inner bottom of the housing 50.

[0042] like Figure 6 The fixing block 40 is provided with a protrusion 41, and the fixing locking block 20 is provided with a groove 22. The groove is far away from the hinge axis 23 between the fixing locking block and the fixing block and is close to the locking pin. The protrusion and the groove cooperate, and there is a left-right gap between the protrusion and the groove.

[0043] The housing 50 is fixedly mounted on the electric product, and the electrical connection plug 43 is electrically connected to the motor inside the electric product. When the operator presses the accessory 60, the accessory moves back and forth, and the electrical connection plug 43 is inserted into the electrical connection plug hole 62 of the accessory. The accessory drives the movable locking block 10, and the locking pin 21 of the fixed locking block moves unidirectionally clockwise / counterclockwise in the track groove 11. When the locking pin 21 moves to the locking groove 111 of the track groove, the operator releases the accessory 60. Under the action of the elastic force of the elastic element 30, the locking pin stays in the locking groove, and the position of the movable locking block 10 is locked. 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 accessory. The lock head locks the accessory, and the accessory cannot be disengaged from the movable locking block. The insertion state of the electrical connection plug 43 and the electrical connection plug hole 62 is maintained.

[0044] During unlocking, the operator presses the accessory 60, drives it forward and backward, and then releases it. This causes the locking pin 21 of the fixed locking block 20 to move unidirectionally clockwise / counterclockwise in the track groove 11. Under the action of the elastic element 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, one end of the accessory exits the housing 50, and the electrical connection plug 43 disengages from the electrical connection plug hole 62. The operator can then pull the accessory 60 to disengage the lock head 12 from the locking groove 61, thereby disengaging the accessory from the movable locking block and allowing it to be removed from the housing 50.

[0045] To ensure that the locking pin 21 on the fixed locking block 20 moves unidirectionally clockwise / counterclockwise within the track groove 11 of the movable locking block, as an improvement of this embodiment, the present invention designs a protrusion 41 and a groove 22 with a lateral gap between them. This gap causes the locking pin 21 to unidirectionally deflect under the limitation of the track groove 11. This deflection prevents the locking pin from retracting into the track it just passed through, but instead allows it to continue moving unidirectionally clockwise / counterclockwise along the track groove 11. Especially during unlocking, when the operator drives the accessory 60 forward and backward and then releases it, the locking pin 21 of the fixed locking block unidirectionally deflects. This deflection prevents the locking pin from retracting into the locking groove 111, but instead allows it to continue moving unidirectionally clockwise / counterclockwise along the track groove 11. Under the action of the elastic element 30, the locking pin 21 can smoothly move to the unlocking groove 112 of the track groove.

[0046] When the locking pin 21 moves unidirectionally clockwise / counterclockwise along the track groove 11, the fixed locking block 20 sways left and right. Assume that when the locking pin 21 enters the locking groove 111 from the unlocking groove 112, it first sways to the left and then to the right; when the locking pin enters the unlocking groove 111 from the locking groove 112, it first sways to the right and then to the 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 protrusion 41 abuts against the left side wall of the groove 22, and the two slide relative to each other, 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 sways to the right, and the locking pin 21 follows, entering the unlocking groove 111. During the process of the locking pin moving from the locking groove 111 into the unlocking groove 112, due to the gap between the right side wall of the protrusion 41 and the right side wall of the groove 22, the fixed locking block 20 swings to the right under the action of the track groove 11, and the locking pin 21 moves accordingly, so that it can smoothly move in one direction clockwise / counterclockwise into the unlocking groove 112.

[0047] Alternatively, accessory 60 is a battery pack.
