Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

It is noted that, unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In the present invention, unless otherwise specified, the use of directional words such as "upper and lower" is generally in reference to the orientation shown in the drawings, or to the vertical, perpendicular or gravitational orientation; likewise, for ease of understanding and description, "left and right" are generally to the left and right as shown in the drawings; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself, but the above directional terms are not intended to limit the present invention.

In order to solve the problem that the use reliability of the locking mechanism is poor and the use experience of a user is influenced in the prior art, the application provides the locking mechanism.

As shown in fig. 1, the latch mechanism includes a housing 10, a latch assembly, a second latch member 50 and an operating structure 60. Wherein the housing 10 has a slide 11. The locking assembly is located in the housing 10, the locking assembly includes a first locking member 20 and a first elastic member 30, the first locking member 20 is pivotally connected to the housing 10, the first elastic member 30 provides an elastic force for the first locking member 20 to rotate around a pivot axis of the first locking member 20, and the locking assembly has an initial state in which a portion of the first locking member 20 extends into the sliding slot 11. The second locking member 50 has a recess 51, and the second locking member 50 slides along the sliding slot 11, so that the first locking member 20 extends into the recess 51 and is stopped by the recess 51, and the locking mechanism is in a locked state. When the first latch 20 is operated to rotate the first latch 20 around its pivot axis, the first latch 20 is disengaged from the recess 51, and the locking mechanism is switched from the locking state to the unlocking state.

By applying the technical scheme of the embodiment, when the locking mechanism is required to be in a locking state, the second locking piece 50 extends into the sliding groove 11 of the housing 10 and slides along the sliding groove 11 until the first locking piece 20 extends into the concave part 51 of the second locking piece 50 and is limited and stopped with the concave part 51, so that the locking mechanism is in the locking state; when the locking mechanism needs to be in the unlocking state, the user operates the first locking member 20 to rotate the first locking member 20 around the pivot shaft thereof, so that the first locking member 20 is disengaged from the recess 51, and the locking mechanism is switched from the locking state to the unlocking state. Thus, the user can separate the first latch member 20 from the recess 51 by operating the first latch member 20, and the latch mechanism is more easily and reliably switched between the locked state and the unlocked state.

Compared with the switching between the locking state and the unlocking state only by means of self elastic deformation of the first locking piece in the prior art, the locking mechanism in the embodiment rotates around a self pivot shaft by the first locking piece 20, so that the first locking piece 20 and the concave part 51 are limited or separated, the problem that the use reliability of the locking mechanism in the prior art is poor, the use reliability of a user is influenced, and the use experience of the locking mechanism is improved.

It should be noted that the manner of operation of the latching mechanism between the locked state and the unlocked state is not limited thereto.

In other embodiments not shown in the drawings, the latch mechanism is switched from the locked state to the unlocked state by operating the first elastic member to rotate the first latch member about its pivot axis, thereby disengaging the first latch member from the recess. Specifically, when the locking mechanism is in the locking state, the first elastic member is compressed, so that the first elastic member drives the first locking member to rotate towards the direction away from the second locking member until the first locking member is separated from the concave portion of the second locking member, and the locking mechanism is switched from the locking state to the unlocking state. Therefore, the first locking piece and the concave part can be separated by operating the first elastic piece by a user, and the locking mechanism is easier and more reliable to switch between the locking state and the unlocking state.

In this embodiment, the above arrangement of the locking mechanism enables the first locking member 20 not to be affected by the material, but by pressing the operating structure 60, the operating structure 60 pushes the first locking member 20, so that the first locking member 20 rotates around its pivot axis, and the locking mechanism is freely switched between the unlocking state and the locking state. Meanwhile, the whole size of the locking mechanism is reduced by the arrangement, and the space is saved.

As shown in fig. 1, the latch mechanism further includes an operating structure 60. The operating structure 60 is disposed on the housing 10, so that by pressing the operating structure 60, the operating structure 60 abuts against the first locking member 20 and pushes the first locking member 20 to rotate around the pivot, so that the first locking member 20 is disengaged from the recess 51. Wherein the first elastic member 30 and the operating structure 60 are located on both sides of the pivot axis, respectively. Like this, when needing the latched device to switch to the state of unblock by the locking state, the user presses operation structure 60 to promote first latch 20 through operation structure 60, and then make first latch 20 rotate around its pivot axle, and then make first latch 20 and concave part 51 separation, realize the unblock. The locking mechanism is easier and simpler to operate by a user due to the arrangement, the operation difficulty of the user is reduced, and the use experience of the user is improved.

Specifically, when the latch mechanism is in the initial state, the second latch member 50 is inserted into the sliding slot 11, so that the second latch member 50 pushes the first latch member 20 to rotate around its pivot shaft, and further the first latch member 20 exits from the sliding slot 11, the second latch member 50 continues to slide until the first latch member 20 slides into the concave portion 51 and is limited and stopped with the concave portion 51, and the latch mechanism is in the locked state; when the locking mechanism needs to be unlocked, the user presses the operating structure 60 to push the first locking member 20 through the operating structure 60, so that the first locking member 20 rotates around the pivot shaft thereof, and the first locking member 20 is separated from the concave portion 51, thereby unlocking.

In the present embodiment, the operation structure 60 is a button or a key. Therefore, the structure is simple, easy to process and realize and convenient for user operation.

As shown in fig. 1, the latch mechanism further includes a second resilient member 40. Wherein the second elastic member 40 is located between the operating structure 60 and the first locking member 20, and the second elastic member 40 provides an elastic force to the operating structure 60 to move toward a side away from the first locking member 20. In this way, the second elastic member 40 can apply an elastic force to the operation structure 60 to prevent the operation structure 60 from sinking into the housing 10 to affect the pressing of the operation structure 60 by the user.

Specifically, when the latch mechanism is in the locked state, the user presses the operating structure 60, the operating structure 60 abuts against the first latch member 20 and pushes the first latch member 20 to rotate around its own pivot, the second elastic member 40 is compressed, and the latch mechanism is switched from the locked state to the unlocked state. When the user no longer presses the operation structure 60, the second elastic member 40 applies an elastic force to the operation structure 60 to reset the operation structure 60.

As shown in fig. 1, the first latch 20 includes a first pivot section 21, a pivot portion 22 and a second pivot section 23 connected in sequence, the first pivot section 21 and the second pivot section 23 are respectively located at two sides of the pivot portion 22, and when the latch mechanism is in the locked state, the operating structure 60 is pressed to make the operating structure 60 abut against the second pivot section 23 and push the second pivot section 23 to rotate around the pivot shaft, so that the first pivot section 21 rotates around the pivot shaft. Wherein the first pivoting section 21 comprises a protrusion 211, the protrusion 211 extending into the sliding slot 11 when the latch assembly is in the initial state. The structure is simple, easy to process and realize, and the processing cost of the locking mechanism is reduced.

Specifically, in the process that the user presses the operating structure 60, so that the second pivoting section 23 is pressed down, the first pivoting section 21 is lifted, and a "seesaw" movement mode is formed, which ensures that the first locking member 20 can rotate around its own pivoting shaft, so as to realize free switching between the unlocking state and the locking state. After the second locking member 50 is inserted into the sliding slot 11, the second locking member 50 pushes the first locking member 20, and the first elastic member 30 is compressed. Then, the second locking member 50 continues to slide until the concave portion 51 moves to the position of the protrusion 211, the first elastic member 30 applies an elastic force to the first locking member 20, the first locking member 20 moves toward the concave portion 51 under the action of the elastic force, so that the protrusion 211 and the concave portion 51 are limited and stopped, the second locking member 50 cannot continue to slide in the sliding slot 11, and the second locking member 50 and the first locking member 20 are locked.

As shown in fig. 1, the second end of the first elastic member 30 contacts the housing 10, and the second end of the second elastic member 40 contacts the operating structure 60, so that when the latch mechanism is in the locked state, the second pivoting section 23 is rotated around its pivoting axis by pressing the operating structure 60, so that the protrusion 211 is disengaged from the recess 51, and the latch mechanism is switched from the locked state to the unlocked state. Thus, the above arrangement ensures that the first pivoting section 21 rotates towards the concave part 51 under the elastic force of the first elastic member 30, so that the protrusion 211 and the concave part 51 are limited and stopped, and the latch mechanism is in a locked state; on the other hand, when the user presses the operation structure 60, the operation structure 60 can push the second pivoting section 23, so that the second pivoting section 23 rotates around the pivoting axis thereof, the protrusion 211 is lifted and separated from the concave part 51, and the latch mechanism is in the unlocking state, thereby improving the use reliability of the latch mechanism and improving the use experience of the user.

Specifically, a first end of the first elastic member 30 contacts the first locking member 20, and a second end of the first elastic member 30 contacts the housing 10. During the process of inserting the second locking member 50 into the sliding slot 11, the second locking member 50 pushes the first locking member 20, so that when the first elastic member 30 is compressed, the second end of the first elastic member 30 applies an elastic force to the housing 10; when the second locking member 50 slides to the concave 51 and the protrusion 211 are disposed correspondingly, the first pivoting section 21 moves toward the concave 51 under the elastic force of the first elastic member 30 to realize the limit stop of the protrusion 211 and the concave 51, and then the locking mechanism is in a locked state. When the user presses the operating structure 60, the operating structure 60 abuts against the second pivoting segment 23 and pushes the second pivoting segment 23, so that the second pivoting segment 23 rotates around the pivoting shaft thereof, the protrusion 211 is lifted and separated from the recess 51, and the latch mechanism is in the unlocked state.

As shown in fig. 1, the first elastic member 30 is a first spring, the first surface of the first pivoting section 21 is provided with a protrusion 211, the first spring abuts against the second surface of the first pivoting section 21, and when the locking assembly is in the initial state, the first spring is in the preset state. Wherein the first surface and the second surface are oppositely arranged. Thus, the above arrangement ensures that the protrusion 211 can move toward the recess 51 (the slide groove 11) when the first elastic member 30 applies the elastic force to the first pivoting section 21, thereby ensuring the movement reliability of the first latch 20. Meanwhile, the structure is simple, the processing and the realization are easy, and the processing cost of the locking mechanism is reduced.

It should be noted that the preset state in this embodiment is a state in which the first spring is in a freely extended state or a compressed state.

In this embodiment, the second surface of the first pivoting section 21 has a first limiting recess, and the first spring extends into the first limiting recess and is in limiting fit with the first limiting recess. Thus, during the process that the first pivoting section 21 compresses the first spring or the first spring pushes the first pivoting section 21, the above arrangement of the first limiting concave part prevents the first spring from separating from the first pivoting section 21 on one hand and affecting the normal use of the latch mechanism; on the other hand, the locking mechanism and the locking mechanism are prevented from shaking relatively in the movement process to influence the operation stability of the locking mechanism.

It should be noted that the limiting manner of the first pivoting section 21 and the first spring is not limited to this. In other embodiments not shown in the drawings, the second surface of the first pivoting section is provided with a first limiting protrusion, and the first spring is sleeved outside the first limiting protrusion. In this way, during the process that the first pivoting section compresses the first spring or the first spring pushes the first pivoting section, the arrangement of the first limiting concave part prevents the first spring from separating from the first pivoting section on one hand and affecting the normal use of the locking mechanism; on the other hand, the locking mechanism and the locking mechanism are prevented from shaking relatively in the movement process to influence the operation stability of the locking mechanism.

As shown in fig. 1, the housing 10 has a mounting groove 12, the second end of the first spring is located in the mounting groove 12, and the groove wall of the mounting groove 12 is connected to the first spring limit stop. Like this, above-mentioned setting further prevents that first spring from taking place about, the fore-and-aft direction from rocking and influencing latched device's normal use, has promoted latched device's operating stability.

As shown in fig. 1, the second elastic element 40 is a second spring, and a convex pillar 61 is disposed on a surface of the operating structure 60 facing the second pivoting section 23, and the second spring is sleeved outside the convex pillar 61. Like this, when the user pressed operation structure 60, the surface and the second pivot section 23 butt of projection 61 to promote second pivot section 23 and rotate around its pivotal axis, the second spring cover is established outside projection 61, in order to prevent projection 61 from taking place to rock and influence first latch member 20's rotation stationarity at the in-process that promotes second pivot section 23, guarantee the structural stability of latch mechanism in the use, can not produce vibration or noise, promoted user's use and experienced.

In the present embodiment, the surface of the second pivoting section 23 facing the second spring has a second limiting recess, and the second spring extends into the second limiting recess and is in limiting fit with the second limiting recess. Like this, the above-mentioned setting of the spacing concave part of second prevents further that projection 61 from taking place to rock and influence the rotation of second pivot section 23, guarantees the structural stability of latched device in the use, can not produce vibration or noise, has promoted user and has used experience.

It should be noted that the limiting manner of the second pivoting section 23 and the second spring is not limited to this. In other embodiments, which are not shown in the drawings, a second limiting protrusion is arranged on the surface of the second pivoting section facing the second spring, and the second spring is sleeved outside the second limiting protrusion. Like this, press the in-process of second spring at operation structure, the rotation that the second pivot section was influenced in the emergence of rocking of the spacing bellied above-mentioned setting of second prevents further that the projection from taking place, guarantees the structural stability of latched device in the use, can not produce vibration or noise, has promoted user's use and has experienced.

As shown in fig. 1, the first latch 20 further includes a bending section 24 between the first pivoting section 21 and the pivoting portion 22, and the bending section 24 is bent toward a side away from the pivoting portion 22 so that the first pivoting section 21 is disposed close to the chute 11 with respect to the second pivoting section 23. Thus, the arrangement ensures that the first pivoting section 21 is arranged close to the sliding groove 11 relative to the second pivoting section 23, so that the locking mechanism can be unlocked and locked, and the use reliability of the locking mechanism is improved.

Specifically, when the latch mechanism is in the initial state, the second latch member 50 is inserted into the slide slot 11, the second latch member 50 pushes the first latch member 20 to rotate around its pivot shaft, so that the protrusion 211 is withdrawn from the slide slot 11, and the first spring is in a compressed state. Then, the second locking member 50 continues to slide along the sliding slot 11 until the concave portion 51 slides to the position of the protrusion 211, and the protrusion 211 moves towards the concave portion 51 and stops with the concave portion 51 under the elastic force of the first spring, so that the locking mechanism is in a locked state. Wherein, during the rotation of the first pivoting segment 21 toward the side far away from the sliding chute 11, the second spring supports the operation structure 60 to prevent the operation structure 60 from sinking to affect the operation of the operation structure 60 by the user.

When a user needs to unlock the latch mechanism, the operating structure 60 is pressed to make the operating structure 60 abut against the second pivoting section 23 and push the second pivoting section 23 to rotate around its own pivoting axis, so that the first pivoting section 21 is lifted, the protrusion 211 is separated from the recess 51, and the latch mechanism is switched from the locking state to the unlocking state.

As shown in fig. 1, the protrusion 211 has a first inclined surface 211a, the second locking member 50 includes a thrust portion 52, the thrust portion 52 has a second inclined surface 521 for pushing the first inclined surface 211a, and the first inclined surface 211a is located on one side of the recess 51 along the sliding direction of the second locking member 50 sliding into the sliding slot 11. Thus, when the second locking fastener 50 pushes the first pivoting section 21, the second inclined surface 521 of the thrust part 52 pushes the first inclined surface 211a, so that on one hand, the insertion of the second locking fastener 50 is more labor-saving and easier; on the other hand, the contact between the first inclined surface 211a and the second inclined surface 521 can reduce the vibration and noise generated by the second locking piece 50 during the process of inserting into the sliding slot 11, thereby improving the operation experience of the user.

Specifically, when the second locking member 50 slides into the sliding slot 11, the first inclined surface 211a pushes the second inclined surface 521, so that the protrusion 211 exits from the sliding slot 11 until the recess 51 moves to the position of the protrusion 211, and the protrusion 211 extends into the recess 51 and is limited and stopped by the recess 51.

As shown in fig. 2 to 4, the latch mechanism is applied in the field of electronic products. Specifically, the electronic product is disposed in the housing 10, the second locking member 50 is connected to the hanging belt 70, the second locking member 50 is slid into the sliding slot 11 of the housing 10 until the first locking member 20 and the second locking member 50 limit the stop, and the hanging belt 70 and the electronic product are locked together. The user separates the hanging strip 70 from the electronic product by pressing the operating structure 60 provided on the housing 10 to separate the first locking member 20 from the second locking member 50.

It should be noted that the application of the latch mechanism is not limited to this. Alternatively, the latching mechanism is applied in the field of lock technology.

From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects:

when the locking mechanism is required to be in a locking state, the second locking piece extends into the sliding groove of the shell and slides along the sliding groove until the first locking piece extends into the concave part of the second locking piece and is limited and stopped with the concave part, so that the locking mechanism is in the locking state; when the locking mechanism is required to be in the unlocking state, a user operates the first locking piece to enable the first locking piece to rotate around the pivot shaft of the first locking piece, or the first elastic piece is compressed to enable the first elastic piece to drive the first locking piece to rotate around the pivot shaft of the first locking piece, so that the first locking piece is separated from the concave portion, and then the locking mechanism is switched from the locking state to the unlocking state. Therefore, the user can realize the separation of the first locking piece and the concave part by operating the first locking piece or the first elastic piece, and the locking mechanism is easier and more reliable to switch between the locking state and the unlocking state.
