[ detailed description ] of the invention

The following examples are further illustrative and supplementary of the present invention and are not intended to limit the invention in any way.

As shown in fig. 1, 2, 3, 7, 8 and 10, the magnetic unlocking buckle device of the present invention includes a pin 10, a box 20 and a magnetic unlocking module 30. Wherein, the pin 10 and the box 20 can be locked and connected together (as shown in fig. 1, 7 and 8) and can be separated from each other. The magnetic unlocking module 30 is independent of the pin 10 and the box 20, and can act on the box 20 to unlock the pin 10 and the box 20 which are locked and connected together, so that the pin 10 and the box 20 are unlocked and separable.

As shown in fig. 3, the pin 10 is provided with a lock tongue 11, the box 20 is provided with a corresponding lock hole and a locking component, and the lock tongue 11 can be inserted into the lock hole along the locking direction and locked by the locking component, so that the pin 10 and the box 20 are locked and connected together. When unlocked using the magnetic unlocking module 30, the latch assembly releases the locking tongue 11, and the locking tongue 11 can be withdrawn from the locking hole so that the pin 10 and the box 20 can be separated from each other.

As shown in fig. 1 and 8, for unlocking, a second magnetic member 31 is provided in the magnetic unlocking module 30, and a first magnetic member 21 is provided in the female buckle 20. When the magnetic unlocking module 30 approaches the female buckle 20, the second magnetic member 31 can attract the first magnetic member 21. For convenience of user operation, during unlocking, the magnetic unlocking module 30 may be abutted against the female buckle 20 so that the second magnetic member 31 attracts the first magnetic member 21, so that the first magnetic assembly 21 may be directly or indirectly moved, and the locking assembly is further actuated, so that the locking assembly is moved from the original position state of locking the lock tongue 11 to the position state of releasing the lock tongue 11, thereby realizing unlocking.

When the magnetic unlocking module 30 attracts the first magnetic member 21 in the female buckle 20 through the second magnetic member 31, the first magnetic member 21 can be directly or indirectly moved in the locking direction X in a direction away from the male buckle 10, so that the locking assembly can be actuated to unlock through the movement of the first magnetic member 21.

In some embodiments, as shown in fig. 1, after the second magnetic member 31 attracts the first magnetic member 21, the magnetic unlocking module 30 is pulled in a direction away from the pin 10 in the locking direction X, and the movement of the magnetic unlocking module 30 indirectly drives the first magnetic member 21 to move in the direction away from the pin 10 in the locking direction X, so as to actuate the latch assembly to unlock. In this embodiment, the second magnetic member 31 attracts the first magnetic member 21, and the latch assembly is not actuated to unlock without actively moving the magnetic unlocking module 30, or is not actuated to a sufficient extent to release the locking bolt 11 to unlock. When the magnetic unlocking module 30 is actively moved in a direction away from the pin 10 in the locking direction, the locking assembly is actuated to unlock, and the box 20 is carried away from the pin 10 along with the movement of the magnetic unlocking module 30, so that the box 20 and the pin 10 can be separated. In other words, the unlocking and the separation of the pin 10 and the box 20 are achieved by the movement of the magnetic unlocking module 30.

In some embodiments, when the second magnetic member 31 attracts the first magnetic member 21, the first magnetic member 21 moves directly in the direction of the second magnetic member 31 due to the magnetic attraction force, thereby actuating the latch assembly to unlock. In this embodiment, when the magnetic unlocking module 30 approaches the female buckle 20 to attract the second magnetic member 31 to the first magnetic member 21, the second magnetic member 31 can move in the female buckle to actuate the latch assembly to unlock without actively moving the magnetic unlocking module 30. When the magnetic unlocking module 30 is actively moved in a locking direction in a direction away from the pin 10, it is only used to separate the pin 10 from the box 20. In other words, the unlocking of the pin 10 and the box 20 is automatically completed by the magnetic attraction between the magnetic unlocking module 30 and the box 20, and is not performed by the movement of the magnetic unlocking module 30.

In the unlocking operation, the magnetic unlocking module 30 may be abutted against the surface of the female buckle 20 to make the second magnetic member 31 and the first magnetic member 21 attract each other, and then the magnetic unlocking module 30 is moved in the direction away from the male buckle 10 in the locking direction X, so that the male buckle 10 and the female buckle 20 can be separated from each other. The unlocking operation direction of the magnetic unlocking module 30 is the same as the locking direction X. When the user operates, when the magnetic unlocking module 30 is close to the female buckle 20, the magnetic attraction between the first magnetic piece 21 and the second magnetic piece 31 can enable the magnetic unlocking module 30 to automatically lean against the corresponding position on the surface of the female buckle 20, and the user can separate the female buckle 20 from the male buckle 10 by only pulling the magnetic unlocking module 30 to move away from the female buckle 20, so that the operation is very simple and convenient. Moreover, the magnetic unlocking module 30 for unlocking is independent of the female buckle 20, and the female buckle 20 and the male buckle 10 can be unlocked only when the magnetic unlocking module 30 is held for unlocking, so that under normal use conditions, accidental unlocking and false unlocking are difficult to occur, and therefore, the safety is high.

As shown in fig. 2, 3, 4, 9 and 10, the latch assembly includes a follower 22, a latch 23 and a resilient member 24.

As shown in fig. 2, 3, 4, 9 and 10, the follower 22 is movable with the first magnetic member 21 in the locking direction X under the attraction of the magnetic unlocking module 30. The follower 22 is coupled to the first magnetic member 21 and moves synchronously. When the first magnetic member 21 is driven by the magnetic unlocking module 30 to move along the locking direction by magnetic attraction, the follower 22 moves synchronously along with the first magnetic member 21. The movement of the follower 22 actuates the latch 23 such that the latch 23 moves in a direction different from the latching direction.

As shown in fig. 2, 3, 4, 9 and 10, the latch 23 is provided with a latch 231. The locking portion 231 is a part of a lock hole, and is used for locking the lock tongue 11. A jack 25 is provided on a side of the female buckle 20 facing the male buckle 10, and the jack 25 and the locking portion 231 together form the locking hole. In a default state, the locking part 231 protrudes out of the range of the insertion hole 25 to be capable of locking the lock tongue 11. The latch 23 is movable under actuation of the follower 22, so that the latch 231 is of a movable configuration. When the tongue 11 is inserted into the box 20 in the locking direction, it can push the latch 231 to continue to advance until it is caught by the latch 231. When the latch 23 is moved under the actuation of the follower 22, the latch 231 can move along the direction of withdrawing from the jack 25, and when the latch 231 moves to a certain extent, the latch 231 cannot continue to lock the lock tongue 11, and at this time, the lock tongue 11 can be released, and the lock tongue 11 can withdraw from the lock hole to separate the pin 10 and the box 20 from each other, so as to realize unlocking.

During the unlocking movement, the follower 22 is moved in the locking direction, and the catch 23 is moved in a direction different from the locking direction. In this embodiment, the catch 23 is moved in a direction perpendicular to the locking direction.

As shown in fig. 2, 3, 4, 9, and 10, in order to actuate the latch 23 by the follower 22, a guide surface 2211 is provided on the follower 22, and an engagement surface 2331 engageable with the guide surface 2211 is provided on the latch 23. The guide surface 2211 is inclined to the locking direction X. The guide surface 2211 is an inclined surface with respect to the locking direction or the moving direction of the latch 23. When the engaging surface 2331 is attached to the guiding surface 2211, the engaging surface 2331 is located at a side of the guiding surface 2211 away from the pin 10, so that when the follower 22 moves in the locking direction away from the pin 10, the guiding surface 2211 acts on the engaging surface 2331 to push the latch 23 to move in a direction perpendicular to the locking direction, so that the latch 231 can move in a direction of exiting from the receptacle 25 to unlock.

As shown in fig. 2, 3, 4, 9 and 10, the elastic member 24 is configured to drive the latch member 23 to move so as to restore the latch portion 231 to extend out of the range of the receptacle 25. In other words, the elastic member 24 is used to drive the latch assembly to return after unlocking. The elastic member 24 may be a spring or the like having elasticity, and is disposed along the moving direction of the latch member 23. In this embodiment, the elastic member 24 is perpendicular to the locking direction, one end thereof abuts against the latch member 23, and the other end thereof abuts against the inner wall of the female buckle 20. When the latch 23 moves under the actuation of the follower 22, the elastic member 24 is compressed to accumulate a force. After the unlocking is completed, after the magnetic unlocking module 30 is removed, the elastic force of the elastic member 24 can push the latch 23 to reset, and the mating surface 2331 of the latch 23 is attached to the guiding surface 2211 of the follower 22, so that the latch 23 pushes the follower 22 to reset during the resetting process of the latch 23, and thus, all resetting of the latch assembly can be realized.

As shown in fig. 2, 3, 4, 9 and 10, in order to restrict the movement of the latch 23 and prevent the latch 23 from being skewed to affect the locking and unlocking effects, a travel hole 232 may be provided in the latch 23, and a first limiting portion 26 may be provided in the female buckle 20. The travel hole 232 is disposed along the moving direction of the latch 23, the first limiting portion 26 is located in the travel hole 232, and the travel hole 232 cooperates with the first limiting portion 26 to restrict the latch 23 to move along a straight line.

As shown in fig. 5, in order to actuate the latch assembly by the magnetic unlocking module 30, a magnet mounting portion 222 is provided on the follower 22, and the first magnetic member 21 is embedded in the magnet mounting portion 222, so that the first magnetic member 21 and the follower 22 can move synchronously. In this embodiment, the magnet mounting portion 222 faces the insertion hole 25. When the magnetic unlocking module 30 is close to the surface of the button 20, the second magnetic member 31 in the magnetic unlocking module 30 attracts the first magnetic member 21, so that the magnetic unlocking module 30 is attracted to the surface of the button 20.

As shown in fig. 2, 3, 4, 9 and 10, in order to constrain the movement of the follower 22, and facilitate the user to obtain a better unlocking experience, the button 20 is provided with a travel guide 27, and the follower 22 is provided with a movement constraint 223. The movement restricting portion 223 is located in the stroke guide portion 27, and is movable in the stroke guide portion 27. The axial direction of the travel guide 27 is set along the locking direction, so that the follower 22 can be restrained from moving along a straight line in the locking direction by the cooperation of the travel guide 27 and the movement restraining part 223, thereby avoiding the influence of the distortion of the follower 22 on the unlocking effect.

The travel guide 27 may be a blind hole or a through hole, and its opening is directed toward the movement restricting portion 223.

In some embodiments, as shown in fig. 4, the travel guide 27 is a through hole. When the magnetic unlocking module 30 is attached to the female buckle 20, the magnetic unlocking module 30 may be attached to the movement restricting portion 223. When the magnetic unlocking module 30 is moved in a direction away from the pin 10 in the locking direction, the follower 22 follows the movement of the magnetic unlocking module 30 to travel in the locking direction away from the pin 10, and the latch 23 is pushed by the guide surface 2211 of the follower 22, so that the latch 23 moves in a direction perpendicular to the locking direction to release the lock tongue 11.

In some embodiments, as shown in fig. 7, the travel guide 27 is a through hole, when the magnetic unlocking module 30 is attached to the female buckle 20, the magnetic unlocking module 30 is not attached to the movement restriction portion 223, and the magnetic unlocking module 30 may provide a travel space 32 for the movement of the movement restriction portion 223 in the locking direction. When the magnetic unlocking module 30 is attached to the female buckle 20, the movement restricting portion 223 moves toward the magnetic unlocking module 30 in the travel guiding portion 27 to move the follower 22 in a direction away from the male buckle 10 in the locking direction, and further pushes the latch 23 through the guiding surface 2211 thereof to move the latch 23 in a direction perpendicular to the locking direction to release the lock tongue 11.

In some embodiments, as shown in fig. 8, 9 and 10, the travel guide 27 is a blind hole opened toward the movement restriction portion 223, and the top of the movement restriction portion 223 is spaced apart from the inner top surface of the travel guide 27. When the magnetic unlocking module 30 is attached to the female buckle 20, the movement restricting portion 223 moves toward the magnetic unlocking module 30 in the travel guiding portion 27 to move the follower 22 in a direction away from the male buckle 10 in the locking direction, and further pushes the latch 23 through the guiding surface 2211 thereof to move the latch 23 in a direction perpendicular to the locking direction to release the lock tongue 11.

As shown in fig. 2, 3, 4, 9, and 10, since the movement restricting portion 223 of the follower 22 is movable in the travel guiding portion 27, a release preventing portion 224 may be provided on the follower 22 to prevent the follower 22 from being released from the female buckle 20. The anti-falling portion 224 cannot pass through the travel guide portion 27, and when the movement restriction portion 223 moves to a certain extent, the anti-falling portion 224 abuts against the inner wall of the box 20, and the follower 22 cannot continue to move, so that the follower 22 can be prevented from falling out of the box 20. The shape of the drop-preventing portion 224 is not limited, and it is connected to one end of the movement restricting portion 223 near the insertion hole 25.

For the magnetic unlocking buckle device of the present invention, the male buckle 10 may be provided with a magnetic member or may not be provided with a magnetic member. As shown in fig. 4 and 9, to facilitate the quick locking connection between the pin 10 and the box 20, a third magnetic member 12 may be disposed in the lock tongue 11. The third magnetic member 12 attracts the first magnetic member 21. When the locking tongue 11 of the pin 10 approaches the box 20 toward the insertion hole 25, the magnetic attraction between the third magnetic member 12 and the first magnetic member 21 will cause the locking tongue 11 to be quickly inserted into the locking hole, so as to achieve the locking connection between the pin 10 and the box 20.

Since the unlocking needs to be performed by the magnetic attraction force between the magnetic unlocking module 30 and the female buckle 20, in order to achieve unlocking, the magnetic attraction force between the second magnetic member 31 of the magnetic unlocking module 30 and the first magnetic member 21 of the female buckle 20 should be greater than the magnetic attraction force between the first magnetic member 21 and the third magnetic member 12.

The working principle of the magnetic attraction unlocking buckle device of the invention is as follows:

when the pin 10 and the box 20 are close to each other along the locking direction, if the third magnetic member 12 is disposed in the pin 10, the magnetic attraction between the third magnetic member 12 and the first magnetic member 21 can enable the pin 10 and the box 20 to be quickly locked together. If the third magnetic member 12 is not provided in the pin 10, the lock tongue 11 is inserted along the lock hole direction, and the lock tongue 11 pushes the locking portion 231 to enter the lock hole and is locked by the locking portion 231, so that the pin 10 and the box 20 are locked and connected together.

When unlocking is required, the magnetic unlocking module 30 is close to the female buckle 20, and the second magnetic piece 31 in the magnetic unlocking module 30 is attracted to the first magnetic piece 21 in the female buckle 20, so that the magnetic unlocking module 30 is attracted to the female buckle 20. The first magnetic element 21 can be indirectly or directly driven to move by the magnetic attraction between the second magnetic element 31 and the first magnetic element 21, so that the follower 22 is driven to move in a direction away from the pin 10 in the locking direction; when the follower 22 moves, the guide surface 2211 pushes the latch 23 to move along the direction perpendicular to the locking direction, so that the latch 231 moves along the direction of withdrawing from the insertion hole 25 to release the lock tongue 11, and the lock tongue 11 can be withdrawn from the lock hole to separate the pin 10 and the box 20 from each other to realize unlocking.

When unlocked, movement of the latch 23 will compress the resilient member 24, causing the resilient member 24 to accumulate force.

After unlocking, when the magnetic unlocking module 30 is removed, the elastic piece 24 pushes the locking piece 23 to reset, so that the locking piece 23 moves along the direction of entering the jack 25; when the latch 23 moves, the matching surface 2331 acts on the guiding surface 2211 of the follower 22 to push the follower 22, so that the follower 22 moves in the locking direction towards the direction approaching the pin 10 to reset, and the latch assembly can be completely reset.

For a better description of the structure of the present invention, the following description is made with reference to specific embodiments:

example 1

As shown in fig. 3 and 4, the pin 10 is provided with a tongue 11, the tongue 11 is protruded, and an end of the tongue is truncated cone-shaped, and is provided with a first conical surface 111.

As shown in fig. 3 and 4, the tongue 11 is provided with a groove 112 for cooperating with the latch 231 to achieve a locking effect. The groove 112 is located slightly away from the end face of the tongue 11. The groove 112 is provided with a second conical surface 1121 having an inclination matching that of the latch 231. When the lock tongue 11 presses the locking portion 231 to push into the lock hole, the locking portion 231 can be locked in the groove portion 112, so that the pin 10 and the box 20 are locked together.

As shown in fig. 4, in order to facilitate the quick locking of the pin 10 and the box 20, a third magnetic member 12 is disposed in the lock tongue 11. In this embodiment, the lock tongue 11 is hollow and cylindrical, the third magnetic member 12 is installed inside the hollow lock tongue 11, and then the third magnetic member 12 can be sealed inside the lock tongue 11 by sealing the opening with a sealing cover.

As shown in fig. 2 and 3, the female buckle 20 includes a housing 28, an unlocking component, and a first magnetic member 21. The housing 28 includes an upper shell 281 and a bottom shell 282 connected in apposition. A receiving cavity is formed between the upper case 281 and the bottom case 282, and the unlocking assembly may be mounted.

As shown in fig. 3, the insertion hole 25 is provided in the bottom case 282. The shape of the insertion hole 25 is not limited, and in this embodiment, it is a circular hole.

As shown in fig. 3, the upper case 281 is provided with the stroke guide 27. The stroke guide 27 is not limited in shape, and in the present embodiment, is a circular through hole, and its position corresponds to the insertion hole 25. In other embodiments, the positions of the travel guide 27 and the insertion hole 25 may not correspond, and may be specifically set as required.
