[ detailed description ] embodiments

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

As shown in fig. 1, fig. 2, fig. 3, fig. 7, fig. 8, and fig. 10, the buckle device for magnetic attraction unlocking according to the present invention includes a male buckle 10, a female buckle 20, and a magnetic unlocking module 30. Wherein, the male buckle 10 and the female buckle 20 can be connected together in a locking manner (as shown in fig. 1, fig. 7 and fig. 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 together, so that the pin 10 and the box 20 are unlocked and can be separated.

As shown in fig. 3, a bolt 11 is arranged on the male buckle 10, a corresponding lock hole and a latch assembly are arranged on the female buckle 20, and the bolt 11 can be inserted into the lock hole along a locking direction and be latched by the latch assembly, so that the male buckle 10 and the female buckle 20 are connected together in a locking manner. When the magnetic unlocking module 30 is used for unlocking, the latch assembly releases the latch tongue 11, and the latch tongue 11 can be withdrawn from the lock hole so that the pin 10 and the box 20 can be separated from each other.

As shown in fig. 1 and 8, in order to unlock, a second magnetic member 31 is provided in the magnetic unlocking module 30, and a first magnetic member 21 is provided in the box 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 the convenience of user operation, during unlocking, the magnetic unlocking module 30 is abutted to the female buckle 20, so that the second magnetic member 31 attracts the first magnetic member 21, and thus the first magnetic member 21 can be directly or indirectly moved, and the locking assembly is 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, and unlocking is realized.

When the magnetic unlocking module 30 attracts the first magnetic member 21 in the female buckle 20 through the second magnetic member 31, it can directly or indirectly move the first magnetic member 21 in the locking direction X in a direction away from the male buckle 10, so that the latch 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 male buckle 10 toward the locking direction X, and the first magnetic member 31 is indirectly driven to move in the direction away from the male buckle 10 toward the locking direction X by the movement of the magnetic unlocking module 30, so as to actuate the latch assembly to unlock. In this embodiment, when the second magnetic member 31 attracts the first magnetic member 21, the latch assembly is not actuated to unlock or is not actuated enough to release the latch tongue 11 to unlock without actively moving the magnetic unlocking module 30 to unlock. When the magnetic unlocking module 30 is actively moved in the locking direction and in the direction away from the male buckle 10, the latch assembly is actuated to unlock, and the female buckle 20 is taken away from the male buckle 10 along with the movement of the magnetic unlocking module 30, so that the female buckle 20 and the male buckle 10 can be separated. In other words, the unlocking of the pin 10 and the box 20 and the separation from each other are achieved by the movement of the magnetic unlocking module 30.

In some embodiments, when the second magnetic member 31 is attracted to the first magnetic member 21, the first magnetic member 31 directly moves in the direction of the second magnetic member 31 in the locking direction due to the magnetic attraction, so as to actuate the latch assembly to unlock. In this embodiment, when the magnetic unlocking module 30 is close to the female buckle 20 such that the second magnetic member 31 is attracted 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 direction away from the pin 10 toward the locking direction, 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 performed 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.

During the unlocking operation, the magnetic unlocking module 30 can abut against the surface of the female buckle 20 to attract the second magnetic member 31 and the first magnetic member 21 to each other, and then the magnetic unlocking module 30 is moved in the direction away from the male buckle 10 towards 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. During the user operation, when magnetism unblock module 30 and box 20 are close to, the magnetic attraction between first magnetism piece 21 and the second magnetism piece 31 can make magnetism unblock module 30 paste and lean on box 20 surperficial relevant position department automatically, and the user only needs to carry magnetism unblock module 30 and does the action of keeping away from box 20, alright separate box 20 and pin 10, and its operation is very simple and convenient. Moreover, the magnetic unlocking module 30 for unlocking is independent of the female buckle 20, and only when the magnetic unlocking module 30 is held for unlocking, the female buckle 20 and the male buckle 10 can be unlocked, so that the conditions of accidental unlocking and mistaken unlocking are difficult to occur under the normal use condition, and the safety is very 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 can move along the latching direction X with the first magnetic member 21 under the attraction of the magnetic unlocking module 30. The follower 22 is coupled to the first magnetic member 21, and both move in synchronization. When the first magnetic member 21 is moved in the locking direction by the magnetic unlocking module 30 through the magnetic attraction, the follower 22 follows the first magnetic member 21 to move synchronously. Movement of the follower 22 may actuate the latch 23 to move the latch 23 in a direction different from the latching direction.

As shown in fig. 2, 3, 4, 9 and 10, the latch 23 has a latch 231. The locking portion 231 is a part of a lock hole, and is used to lock the latch bolt 11. A plug hole 25 is formed in one side of the female buckle 20 facing the male buckle 10, and the plug hole 25 and the locking part 231 together form the locking hole. In a default state, the locking portion 231 extends out of the range of the insertion hole 25 to lock the lock tongue 11. The latch 23 is movable by the actuation of the follower 22, and thus the latch 231 is in a movable configuration. When the latch tongue 11 is inserted into the female buckle 20 in the locking direction, it may push the latching portion 231 to continue to advance until it is latched by the latching portion 231. When the locking piece 23 is actuated by the follower 22 to move, the locking portion 231 can move in a direction of withdrawing from the insertion hole 25, and when the locking portion 231 moves to a certain extent, the locking portion 231 cannot continuously lock the lock tongue 11, and at this time, the lock tongue 11 can be released, and the lock tongue 11 can be withdrawn from the insertion hole to separate the male buckle 10 and the female buckle 20 from each other, so as to achieve 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 latch 23 moves in a direction perpendicular to the latching 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 a mating surface 2331 that can be abutted against the guide surface 2211 is provided on the latch 23. The guide surface 2211 is inclined to the latching 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 mating surface 2331 is fitted to the guide surface 2211, the mating surface 2331 is located on the side of the guide surface 2211 away from the male buckle 10, so that when the follower 22 moves in the locking direction away from the male buckle 10, the guide surface 2211 acts on the mating surface 2331 to push the locking piece 23 to move in the direction perpendicular to the locking direction, so that the locking piece 231 can move in the direction of withdrawing from the insertion hole 25 to be unlocked.

As shown in fig. 2, 3, 4, 9 and 10, the elastic member 24 is used to drive the locking member 23 to move so that the locking portion 231 is restored to extend out of the insertion hole 25. In other words, the resilient member 24 is used to actuate the latch assembly to reset after unlocking. The elastic member 24 may be a member having elasticity such as a spring, which is disposed along the moving direction of the latch 23. In this embodiment, the elastic member 24 is perpendicular to the locking direction, and has one end abutting against the locking member 23 and the other end abutting against the inner wall of the female buckle 20. When the latch 23 is moved by the actuation of the follower 22, the resilient member 24 is compressed and stores force. After the magnetic unlocking module 30 is removed after unlocking is completed, the elastic force of the elastic member 24 may push the locking member 23 to reset, and the mating surface 2331 of the locking member 23 is abutted to the guiding surface 2211 of the follower 22, so that the locking member 23 pushes the follower 22 to reset during the resetting of the locking member 23, thereby achieving the complete resetting of the latch assembly.

As shown in fig. 2, 3, 4, 9 and 10, in order to restrict the movement of the locking piece 23 and prevent the locking piece 23 from being inclined to affect the locking and unlocking effects, a stroke hole 232 may be formed in the locking piece 23, and a first stopper 26 may be formed in the female buckle 20. The stroke hole 232 is followed the moving direction setting of latch fitting 23, first spacing portion 26 is located in the stroke hole 232, stroke hole 232 and the cooperation of first spacing portion 26, alright restraint latch fitting 23 is along rectilinear movement.

As shown in fig. 5, in order to actuate the latch assembly by magnetically unlocking the 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 female buckle 20, the second magnetic member 31 in the magnetic unlocking module 30 is attracted to the first magnetic member 21, so that the magnetic unlocking module 30 is attracted to the surface of the female buckle 20.

As shown in fig. 2, 3, 4, 9 and 10, in order to restrict the movement of the follower 22 and facilitate the user to obtain a better unlocking experience, a travel guide 27 is disposed on the box 20, and a movement restriction 223 is disposed on the follower 22. The movement restraint portion 223 is located within the stroke guide portion 27, and is movable within the stroke guide portion 27. The axial direction of the stroke guide part 27 is arranged along the locking direction, so that the follower 22 can be restrained from moving along a straight line in the locking direction through the matching of the stroke guide part 27 and the movement restraining part 223, and the influence of the deflection of the follower 22 on the unlocking effect is avoided.

The stroke guide 27 may be a blind hole or a through hole, and the opening thereof faces the movement restricting portion 223.

In some embodiments, as shown in fig. 4, the stroke 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 male buckle 10 in the locking direction, the follower 22 follows the movement of the magnetic unlocking module 30 and advances in the locking direction away from the male buckle 10, and the guide surface 2211 of the follower 20 pushes the latch 23, so that the latch 23 moves in a direction perpendicular to the locking direction to release the latch tongue 11.

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

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

As shown in fig. 2, 3, 4, 9 and 10, since the movement restraining portion 223 of the follower 22 can move in the stroke guiding portion 27, in order to prevent the follower 22 from coming off the female buckle 20, a coming-off preventing portion 224 can be provided on the follower 22. The run-length guide 27 prevents the run-length preventing portion 224 from passing through, and when the movement restricting portion 223 moves to a certain extent, the run-length preventing portion 224 abuts against the inner wall of the female snap 20, and the follower 22 cannot move any further, so that the follower 22 is prevented from coming out of the female snap 20. The shape of the stopper 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 buckle device unlocked by magnetic attraction of the invention, the male buckle 10 may or may not be provided with a magnetic member. As shown in fig. 4 and 9, in order to facilitate the quick-locking connection between the male buckle 10 and the female buckle 20, a third magnetic member 12 may be disposed in the lock tongue 11. The third magnetic member 12 is attracted to the first magnetic member 21. When the bolt 11 of the male buckle 10 approaches the female buckle 20 toward the insertion hole 25, the magnetic attraction between the third magnetic member 12 and the first magnetic member 21 will cause the bolt 11 to be rapidly inserted into the insertion hole to achieve the locked connection between the male buckle 10 and the female buckle 20.

Owing to need unblock through the magnetic attraction between magnetism unblock module 30 and the box 20, consequently, for realizing the unblock, magnetism unblock module 30 the second magnetism piece 31 with magnetic attraction between the first magnetism piece 21 of box 20 should be greater than magnetic attraction between first magnetism piece 21 and the third magnetism piece 12.

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

when the male buckle 10 and the female buckle 20 are moved close to each other in the locking direction, if the third magnetic member 12 is provided in the male buckle 10, the magnetic attraction between the third magnetic member 12 and the first magnetic member 21 can make the male buckle 10 and the female buckle 20 be quickly locked together. If the third magnetic member 12 is not present in the male buckle 10, the locking tongue 11 is inserted into the lock hole, and the locking tongue 11 pushes the locking portion 231 to enter the lock hole to be locked by the locking portion 231, so that the male buckle 10 and the female buckle 20 are locked and connected together.

When unlocking is needed, the magnetic unlocking module 30 is close to the female buckle 20, and the second magnetic member 31 in the magnetic unlocking module 30 and the first magnetic member 21 in the female buckle 20 are attracted to enable the magnetic unlocking module 30 to be attracted to the female buckle 20. The first magnetic member 21 can be indirectly or directly urged to move by the magnetic attraction between the second magnetic member 31 and the first magnetic member 21, so as to drive the follower 22 to move in the locking direction in the direction away from the male buckle 10; when the follower 22 moves, the locking piece 23 is pushed by the guide surface 2211 thereof to move in the direction perpendicular to the locking direction, so that the locking part 231 moves in the direction of exiting the insertion hole 25 to release the lock tongue 11, and the lock tongue 11 can be pulled out from the lock hole to separate the male buckle 10 and the female buckle 20 from each other to achieve unlocking.

When unlocking, the movement of the latch 23 compresses the elastic member 24, and the elastic member 24 is charged.

After the unlocking is completed, when the magnetic unlocking module 30 is taken off, 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 is moved, its engagement surface 2331 acts on the guide surface 2211 of the follower 22 to push the follower 22, so that the follower 22 is moved in the latching direction in the direction close to the pin 10 to be reset, thereby completely resetting the latch assembly.
