[ 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 and 2, the buckle device for shifting to unlock according to the present invention includes a first connection module 10 and a second connection module 20.

As shown in fig. 2 and 3, the first connection module 10 and the second connection module 20 are lockable together and separable from each other. The first connection module 10 is provided with a lock tongue 11, the second connection module 20 is provided with a corresponding lock hole 21, and the lock tongue 11 can be inserted into the lock hole 21 along the locking direction X so that the first connection module 10 and the second connection module 20 are locked and connected together; when unlocked, the latch 11 can be withdrawn from the lock hole 21 to separate the first connection module 10 and the second connection module 20 from each other.

As shown in fig. 2, 3, 6, 9, 12 and 13, the second connection module 20 is provided with an unlocking member 23 and a locking portion 231. The latch 231 may be moved by the actuation of the unlocking member 23. In some embodiments, as shown in fig. 6 and 9, the latching portion 231 is integrally designed with the unlocking member 23, that is, the latching portion 231 is a part of the unlocking member 23. In some embodiments, as shown in fig. 12 and 13, the latching portion 231 is disposed separately from the unlocking member 23, that is, the latching portion 231 is an element other than the unlocking member 23.

As shown in fig. 2, 3, 6, 9, 12 and 13, the unlocking member 23 is pivoted in the second connection module 20, and it can actuate the latch 231. As shown in fig. 2 and 3, the unlocking member 23 is provided with a toggle portion 233, and the toggle portion 233 is used for a user to toggle to cause the unlocking member 23 to pivot. When the unlocking member 23 is pivoted in the housing 22 of the second connection module 20, part or all of the toggle part 233 is located outside the housing 22 of the second connection module 20. The shape and size of the toggle part 233 can be set as required.

As shown in fig. 2 and 3, the unlocking member 23 is located inside the second connection module 20 except for the toggle portion 233.

As shown in fig. 3, the latching part 231 latches the latch tongue 11 so that the first connection module 10 and the second connection module 20 are connected to each other.

As shown in fig. 2 and 3, the latch 231 is a part of the lock hole 21. The second connection module 20 is provided with a fixing hole 223. The fixing hole 223 is sized to allow the latch 11 to freely enter and exit. The fixing hole 223 and the latching part 231 together form a locking hole 21 that can latch the latch tongue 11. The lock hole 21 locks or releases the latch 11 by a change in position of the latching portion 231. As shown in fig. 3, when the latching part 231 is protruded within the range of the fixing hole 223, it has a capability of latching the latch 11, and at this time, the first connection module 10 and the second connection module 20 may be connected to each other. When the latching part 231 moves to a certain extent in a direction of exiting the fixing hole 223, for example, completely exits the range of the fixing hole 223, the latching part 231 loses the ability to latch the latch tongue 11, and the first connection module 10 and the second connection module 20 can be separated from each other.

As shown in fig. 2, the latching portion 231 protrudes from the fixing hole 223 in a default state, and the latching portion 231 is movable in a direction of withdrawing from the fixing hole 223 by the actuation of the unlocking member 23.

When the unlocking member 23 is pushed in a direction away from the first connection module 10 (i.e., the direction X), the unlocking member 23 pivots to actuate the latching portion 231, so that the latching portion 231 can be outwardly withdrawn from the range of the fixing hole 223 to release the latch tongue 11 for unlocking.

Further, as shown in fig. 2, 3, 6, 9, 12 and 13, in order to allow the latch 231 after the movement to be reset to a default state, i.e., to extend out of the fixing hole 223, a first elastic connection portion 234 is provided at one end of the latch 231, which is far from the fixing hole 223. The first elastic connection portion 234 has elasticity, and thus, the movement of the latching portion 231 can be satisfied and the latching portion 231 can be reset by the elasticity.

In some embodiments, as shown in fig. 6 and 9, the first elastic connection portion 234 is integrally connected to the unlocking member 23.

In some embodiments, as shown in fig. 12 and 13, the first elastic connection portion 234 is not connected to the unlocking member 23, but is fixedly connected or detachably connected to the housing 22 of the second connection module 20.

When the latching portion 231 is withdrawn from the range of the fixing hole 223 by the actuation of the unlocking member 23, the first elastic connection portion 234 is compressed and accumulated. When the external force is lost, the first elastic connection portion 234 is restored by the elastic force to move the latching portion 231 toward the fixing hole 223 and is restored to a range protruding out of the fixing hole 223.

Further, as shown in fig. 7, 8, 10, and 11, in order to actuate the latching portion 231 to release the latch tongue 11 by the unlocking member 23, a pressing portion 237 is provided on the unlocking member 23, and a pushing portion 238 is provided on the latching portion 231. The pressing portion 237 is rigidly formed on the unlocking member 23. When the unlocking member 23 is pushed in a direction away from the first connection module 10 to pivot the unlocking member 23, the position of the pressing portion 237 is changed to push the pushing portion 238, so that the latching portion 231 is pushed to move in a direction of exiting the fixing hole 223, and the latching portion 231 is released from the locking tongue 11.

As shown in fig. 2 and 3, in order to facilitate the quick locking of the first connection module 10 and the second connection module 20, a first magnet 12 is disposed in the first connection module 10, and a second magnet 24 is disposed in the second connection module 20. The first magnet 12 and the second magnet 24 are attracted to each other. When the latch bolt 11 is facing the lock hole 21 to be inserted, the magnetic force between the first magnet 12 and the second magnet 24 may assist the latch bolt 11 to be quickly inserted into the lock hole 21.

As shown in fig. 6 to 13, in order to reversely pivot the pivoting unlocking member 23 for resetting, a second elastic connection portion 235 is provided on the unlocking member 23. The second elastic connection portion 235 has elasticity, and abuts against the housing of the second connection module 20. The second elastic connection portion 235 is located at an end of the unlocking member 23 opposite to the toggle portion 233. When the unlocking member 23 is pushed in a direction away from the first connection module 10 to pivot the unlocking member 23, the second elastic connection 235 is pressed by the housing to be elastically deformed, thereby accumulating elastic force. When the unlocking member 23 loses the external operation force, the second elastic connection portion 235 may be restored to force the unlocking member 23 to pivot toward the reset state.

Further, as shown in fig. 2, 3, 4, 9, 10, 11, and 13, in order to reduce the opening force during unlocking, a push-out portion 232 may be provided on the unlocking member 23. As shown in fig. 2 and 3, the extruding part 232 may extend out of the fixing hole 223 and may move in a direction different from the direction of the latch 11. When the unlocking member 23 is pushed in a direction away from the first connection module 10 to pivot the unlocking member 23, the extruding part 232 may push the latch 11 to move in a direction away from the second connection module 20, thereby facilitating the separation of the first connection module 10 and the second connection module 20.

Further, as shown in fig. 2 and 11, an extrusion inclined curved surface 2321 is provided on a side of the extrusion portion 232 facing the fixing hole 223, and a first conical surface 111 is provided on a free end of the latch 11. As shown in fig. 3, the extrusion ramp 2321 may be engaged with the first conical surface 111. When the unlocking member 23 is pushed in a direction away from the first connection module 10 to pivot the unlocking member 23, the extruding part 232 moves in a direction perpendicular to the locking direction, and the extruding inclined curved surface 2321 acts on the first conical surface 111 of the locking tongue 11 to push the locking tongue 11 out in the locking direction, so as to assist the first connection module 10 and the second connection module 20 to be separated. As shown in fig. 3, when the first connection module 10 and the second connection module 20 are connected to each other, the inclined extrusion curved surface 2321 of the extrusion portion 232 is located on the first conical surface 111 of the latch bolt 11 or attached to the first conical surface 111.

In addition, the extruding part 232 can also extrude into the position where the first magnet 12 and the second magnet 24 are combined to reduce the attraction force between the first magnet 12 and the second magnet 24, thereby facilitating the exit of the locking bolt 11. When the unlocking member 23 is pivoted by pulling the unlocking member 23 in a direction away from the first connection module 10, the extruding part 232 moves in a direction of entering the fixing hole 223 to space the first magnet 12 and the second magnet 24 apart to reduce the magnetic attraction therebetween, thereby facilitating the separation of the first connection module 10 and the second connection module 20.

As shown in fig. 9, 10, 11 and 13, in order to satisfy the displacement movement and the restoration of the extruding part 232, the extruding part 232 is connected to the unlocking member 23 through the second elastic connection part 235.

The second elastic connection portion 235 has elasticity, which can provide conditions for a position change of the extrusion portion 232. Therefore, the second elastic connection portion 235 plays an elastic connection role on one hand and an elastic restoration role on the other hand. The second elastic connection portion 235 may be formed in a desired shape and size.

As shown in fig. 6 to 13, the position where the unlocking member 23 is pivoted to the second connection module 20 is located between the toggle portion 233 and the pressing portion 237.

The working principle of the buckle device for pulling and unlocking the buckle device is as follows:

as shown in fig. 2, when the first connection module 10 and the second connection module 20 are brought close to each other in the locking direction, the magnetic attraction between the first magnet 12 and the second magnet 24 causes the first connection module 10 and the second connection module 20 to be quickly and lockingly connected together (as shown in fig. 3).

When the unlocking is required, as shown in fig. 3, the toggle part 233 of the unlocking part 23 is toggled in a direction (direction X) away from the first connection module 10 to pivot the unlocking part 23, so that the pressing part 237 can push the pushing part 238 to drive the latching part 231 to move in a direction away from the fixing hole 223 to release the latch bolt 11, and at this time, the latch bolt 11 can be pulled out from the second connection module 20 to separate the first connection module 10 and the second connection module 20 from each other.

During the unlocking process, the latch 231 moves to compress the first elastic connection part 234, and the unlocking piece 23 pivots to compress the second elastic connection part 235, so that the first elastic connection part 234 and the second elastic connection part 235 accumulate a certain elastic force. After the latch 11 is released from the second connection module 20, if the user releases the unlocking member 23, the unlocking member 23 pivots in the direction opposite to the toggle direction under the elastic force of the second elastic connection portion 235, the latching portion 231 is reset to extend into the range of the fixing hole 223 under the elastic force of the first elastic connection portion 234, and the pushing portion 238 pushes the pressing portion 237 to finally reset the unlocking member 23 to the default state completely.

When the extrusion portion 232 is provided, the extrusion portion 232 may act on the end of the latch tongue 11 to facilitate the latch tongue 11 to move away from the second connection module 20 when unlocking, thereby further facilitating the separation of the first connection module 10 and the second connection module 20 from each other.

Example 1

As shown in fig. 6, the second connection module 20 includes a housing 22, an unlocking member 23, and a second magnet 24. As shown in fig. 6, 7 and 8, the unlocking member 23 includes a toggle portion 233, a first elastic coupling portion 234, a latch portion 231, a second elastic coupling portion 235, a pushing portion 238 and a pressing portion 237 which are integrally formed.

As shown in fig. 2 and 6, the housing 22 is used to provide the unlocking member 23 and the second magnet 24, and the shape and structure thereof may be set as required. Typically, to facilitate assembly, it typically includes a first housing 221 and a second housing 222 that are joined together in a mating relationship. When the first casing 221 and the second casing 222 are connected together, a receiving cavity is formed inside the first casing and can be used for installing the unlocking piece 23 and the second magnet 24. In addition, in order to facilitate the arrangement of the second magnet 24, a magnet holder 25 may be provided inside thereof, and the shape and structure of the magnet holder 25 may be arranged as needed, which is preferable to facilitate the arrangement of the second magnet 24.

As shown in fig. 2 and 6, in order to facilitate the insertion of the latch 11 of the first connection module 10 into the second connection module 20, the housing 22 is provided with the fixing hole 223. The fixing hole 223 is shaped as required, and in this embodiment, it is a circular hole.

As shown in fig. 2, the position of the second magnet 24 in the second connection module 20 is opposite to the position of the fixing hole 223, so that the second magnet can be easily attracted to the first magnet 12 in the latch 11.

As shown in fig. 7 and 8, the first elastic connection portion 234 is connected between the toggle portion 233 and the latching portion 231. Preferably, one end of the first elastic connecting portion 234 is connected to a middle portion of an end of the toggle portion 233, and the other end thereof is connected to a middle portion of the latching portion 231, so that the latching portion 231 is spaced apart from the toggle portion 233. The shape and number of the first elastic connection portions 234 may be set as desired. In this embodiment, the first elastic connection portion 234 is formed in a wavy bent shape, and the bent direction thereof is parallel to the axial direction of the fixing hole 223.

As shown in fig. 7 and 8, one end of the second elastic connecting portion 235 is connected to the toggle portion 233, and the other end thereof is a free end. The second elastic connection portion 235 is distributed outside the first elastic connection portion 234 and the latching portion 231. In this embodiment, the second elastic connection portions 235 are respectively disposed on both sides of the first elastic connection portion 234 and the latching portion 231. In other embodiments, the second elastic connection portion 235 may be disposed only on one side of the first elastic connection portion 234 and the latch 231. The shape of the second elastic connection portion 235 is not limited, and it may provide an elastic force for the pivotal reset of the unlocking member 23. In this embodiment, the second elastic connection portion 235 is formed in a wavy bent shape, and the bending direction thereof is parallel to the axial direction of the fixing hole 223.

As shown in fig. 7 and 8, one end of the latching portion 231 facing the extruding portion 232 is arc-shaped, and is used for latching the latch tongue 11. In order to facilitate the bolt 11 to be pushed into the lock hole 21 to achieve the locking connection, a lead-in inclined curved surface 2311 is provided at a side of the locking part 231 facing the fixing hole 223. The guiding inclined curved surface 2311 is beneficial to the extrusion of the lock tongue 11 and is extruded into the lock hole 21 in a proper position, so that the locking part 231 can lock the lock tongue 11.

As shown in fig. 7 and 8, the pressing portion 237 is disposed on an inner wall of a joint of the toggle portion 233 and the second elastic connecting portion 235. The pressing portion 237 is formed in a protruding shape which protrudes from the inner wall of the unlocking member 23 and is integrally formed therewith. In this embodiment, two of the pressing portions 237 are symmetrically disposed and located near the second elastic connecting portion 235.

As shown in fig. 7 and 8, the pushing portion 238 is provided on a wall portion of the latching portion 231 facing the pressing portion 237. The pushing portion 238 is protruded with respect to the wall surface around it, so that an action space is provided for the pressing of the pressing portion 237. In a default state, the pushing portion 238 is spaced from the pressing portion 237 without contacting. When the unlocking member 23 is moved in a direction away from the first connection module 10 to pivot the unlocking member 23, the pressing portion 237 is changed in position to contact the pushing portion 238 to push the pushing portion 238. The pushing portion 238 is located on a side of the pressing portion 237 facing the toggle portion 233, so that the pressing portion 237 can push the pushing portion 238 along the direction of the toggle portion 233, thereby forcing the latching portion 231 to move towards the toggle portion 233 and exit the range of the fixing hole 223, thereby facilitating the disengagement of the locking bolt 11. In this embodiment, two pushing portions 238 are symmetrically disposed and respectively distributed on the wall portions at the two ends of the latching portion 231.

As shown in fig. 7 and 8, the rotation shaft 239 is integrally formed with the unlocking member 23, protrudes from an outer sidewall of the unlocking member 23, and is located between the toggle portion 233 and the pressing portion 237. The axial direction of the rotating shaft portion 239 is perpendicular to the axial direction of the fixing hole 223. The shaft 239 is cylindrical.

To assemble the unlocking member 23, a corresponding pivot hole (not shown) is formed in the housing 22, and the pivot hole is engaged with the pivot portion 239, so that the unlocking member 23 is pivotally connected to the second connecting module 20 and can pivot around the pivot portion 239.

In other embodiments, the rotating shaft portion 239 may be replaced by a rotating shaft member (not shown), and corresponding rotating shaft holes are respectively formed on the unlocking member 23 and the housing 22, and the rotating shaft member is assembled in the rotating shaft hole, so that the unlocking member 23 is pivoted in the second connecting module 20.

As shown in fig. 6, the second connection module 20 is thus formed: the unlocking member 23 is pivoted to the housing 22 and can rotate around the rotating shaft 239; the housing 22 is provided with a fixing hole 223, the unlocking member 23 is provided with a locking portion 231, and the locking portion 231 extends out of the fixing hole 223 in a default state to form a locking hole 21 for locking the lock tongue 11 together with the fixing hole 223. The latching portion 231 is movable to move out of the fixing hole 223 to release the latch 11. The toggle part 233 of the unlocking part 23 is at least partially located outside the housing 22 and can be used for toggling, and the first elastic connecting part 234, the second elastic connecting part 235, the latch part 231, the extrusion part 237 and the pushing part 238 of the unlocking part 23 are all located inside the housing 22; in a default state, the latch 231 and the second elastic connecting portion 235 abut against the inner wall of the housing 22. When the unlocking member 23 is pushed in a direction away from the first connection module 10 to pivot the unlocking member 23, the pressing portion 237 is changed in position to push the pushing portion 238, so that the latching portion 231 is forced to move in a direction of exiting the fixing hole 223 to release the latch tongue 11; at the same time, the second elastic connection portion 235 is elastically deformed to store force.

As shown in fig. 5, a latch 11 is disposed on the first connection module 10, the latch 11 is protruded, and the end portion thereof is truncated cone-shaped and has a first conical surface 111. The first conical surface 111 is used for pressing the lead-in oblique curved surface 2311 to facilitate the bolt 11 to enter the lock hole 21, and meanwhile, the first conical surface 111 is also used for interacting with the lead-out oblique curved surface 2321 to facilitate the bolt to exit from the lock hole 21 during unlocking.

As shown in fig. 5, the latch 11 is provided with a groove portion 112 for cooperating with the latch portion 231 to achieve a locking effect. The groove portion 112 is located slightly away from the end surface of the bolt 11. In this embodiment, the groove portion 112 is annular. In other embodiments, the groove portion 112 may also be configured to match the shape and size of the latching portion 231. The groove portion 112 is provided with a second conical surface 113 having an inclination matching the latching portion 231. When the lock tongue 11 presses the latch portion 231 and pushes the lock hole 21, the latch portion 231 is latched in the groove portion 112, so that the first connection module 10 and the second connection module 20 are connected together in a locked manner.

In order to facilitate the quick locking of the first connection module 10 and the second connection module 20, a first magnet 12 is provided in the latch bolt 11. The arrangement direction of the first magnet 12 can be set according to the requirement, in this embodiment, the bolt 11 is in a hollow cylinder shape, the first magnet is installed inside the hollow bolt 11, and then the opening can be sealed by the sealing cover so that the first magnet 12 is sealed inside the bolt 11.

Therefore, the buckle device for shifting and unlocking in the embodiment is formed, and the working principle is as follows:

when the first connection module 10 and the second connection module 20 are close to each other in the locking direction, the magnetic attraction between the first magnet 12 and the second magnet 24 will cause the latch 11 of the first connection module 10 to be inserted into the latch hole 21 of the second connection module 20 in alignment. During the insertion process, the latch 231 is provided with the guiding inclined curved surface 2311, and the latch 231 is provided through the first elastic connecting portion 234, so that the latch 11 can press the latch 231 and enter the second connection module 20, so that the latch 231 is latched in the groove portion 112 of the latch 11, and the first connection module 10 and the second connection module 20 are lockingly connected (as shown in fig. 3).

When unlocking is required, the unlocking piece 23 is shifted in a direction away from the first connection module 10, so that the unlocking piece 23 pivots around the rotating shaft portion 239, and the pressing portion 237 can push the pushing portion 238 to drive the latching portion 231 to move in a direction away from the fixing hole 223 to release the latch tongue 11, so that the first connection module 10 and the second connection module 20 can be separated from each other.

During unlocking, the latch 231 moves to compress the first elastic connection portion 234, so that the first elastic connection portion 234 is compressed to store force. Since the second elastic connection portion 235 of the unlocking member 23 abuts against the inner wall of the housing 22, the second elastic connection portion 235 is compressed and accumulates force when the unlocking member 23 pivots.

After the latch 11 is released from the second connection module 20, if the user releases the unlocking member 23, the unlocking member 23 pivots in the reverse direction under the elastic force of the second elastic connection portion 235 to urge the unlocking member 23 to pivot in the reset direction; under the action of the first elastic connection portion 234, the latching portion 231 is reset to extend into the fixing hole 223, and the pushing portion 238 pushes the pressing portion 237 to reset the unlocking member 23 to the position where the unlocking member is not toggled, so as to achieve complete reset.

The design of the extrusion inclined curved surface 2321 makes the orientation of the extrusion part 232 the end of the latch part 231 is sharp, and then can be conveniently extruded between the attraction parts of the first magnet 12 and the second magnet 24, namely, between the end surface of the lock tongue 11 and the magnet frame 25, so as to reduce the magnetic attraction between the first magnet 12 and the second magnet 24, thereby facilitating the exit of the lock tongue 11. In addition, the extruded oblique curved surface 2321 may also act on the free end of the latch bolt 11 to push the latch bolt 11 to move in the locking direction to exit the lock hole 21. When the first connection module 10 and the second connection module 20 are locked together, the inclined extrusion curved surface 2321 of the extrusion portion 232 is located above the first conical surface 111 of the latch bolt 11, or attached to the first conical surface 111 (as shown in fig. 3).

The extrusion part 232 has the following action principle:

as shown in fig. 3, when the unlocking member 23 is pushed in a direction away from the first connection module 10 to pivot the unlocking member 23, the extruding portion 232 moves in a direction of entering the fixing hole 223, so as to be extruded between the portions where the first magnet 12 and the second magnet 24 are combined to reduce the magnitude of the magnetic force between the first magnet 12 and the second magnet 24, and the locking tongue 11 is forced to move in a direction away from the second connection module 20 by the extruding inclined curved surface 2321 to separate the first connection module 10 from the second connection module 20.
