In the prior art, a gear and rack transmission structure is usually adopted between the key and the clamping tongue, and the structure is complex and is easy to have the problem of clamping stagnation, namely the problem of high failure rate. Therefore, how to provide a transmission structure which is applicable to the space between the key and the latch and has simple structure and low failure rate is a technical problem to be solved by the technical personnel in the field.

In view of this, the present invention provides a wearing apparatus, which includes a mounting base 60, a functional main body 70, and a locking mechanism for detachably mounting the functional main body 70 to the mounting base 60, and in one embodiment of the present invention, the locking mechanism includes:

a base 10;

a latch 20 slidably connected to the base 10 along a first direction and having an extended position and a retracted position, wherein the latch 20 at least partially protrudes from the base 10 and is used for connecting the functional body 70;

a shift lever 30 rotatably connected to the base 10; and

a key 40 slidably connected to the base 10 along a second direction and having a first position and a second position; one end of the shift lever 30 is movably abutted against the latch 20, and the other end is movably abutted against the button 40, so that in the process that the button 40 slides from the first position to the second position, the button 40 pushes the shift lever 30 to rotate, and the latch 20 slides from the extended position to the retracted position.

In the technical scheme of the invention, the shift lever 30 connected to the base 10 is rotated, and the displacement of the key 40 can be converted into the displacement of the latch 20 by utilizing the lever principle, so that the locking and unlocking of the functional main body 70 are realized. The transmission structure has the advantages of simple structure and convenient assembly, thereby reducing the manufacturing cost. Compared with a gear meshing transmission mode, the rotation mode of the shift lever 30 is less prone to causing jamming, namely, the technical scheme of the invention has the advantages of stable work and low failure rate.

Referring to fig. 1, in an embodiment, two of the latch 20, the lever 30 and the button 40 are disposed in a one-to-one correspondence, and the two buttons 40 are disposed on two opposite sides of the base 10. Specifically, the two sets of locking mechanisms operate independently and do not interfere with each other, that is, only after the keys 40 on both sides are pressed, both the locking tongues 20 slide to the retracted position, and the functional body 70 is unlocked. Therefore, the problem that the functional body 70 falls down, is damaged or is lost due to the fact that the user mistakenly touches one of the keys 40 to unlock the functional body 70 and accidentally breaks away from the mounting seat can be avoided. Of course, in other embodiments, the two keys may be disposed on the same side of the base, such as the upper surface of the base.

Referring to fig. 2, in an embodiment, the button 40 is disposed adjacent to the rotation axis 11 of the lever 30 and abuts against the lever 30. In this way, the effect of enlarging the pressing stroke of the key 40 is achieved, that is, the latch 20 can be driven to perform a larger displacement stroke with a smaller pressing stroke of the key 40. Therefore, under the same design requirement of the displacement stroke of the latch 20, the pressing stroke of the key 40 can be smaller, so that the height of the key 40 protruding out of the base 10 can be smaller, which is beneficial to improving the small and attractive appearance of the product, and further improving the user experience. Of course, in other embodiments, the key may be abutted to the position of the shift lever and disposed away from the rotation axis of the shift lever.

Referring to fig. 2, in an embodiment, the base 10 has a rotating shaft 11, and the shift lever 30 is rotatably connected to the rotating shaft 11; the key 40 and the latch 20 are respectively disposed on opposite sides of the rotating shaft 11, and the key is abutted against the shift lever 30 and the latch 20 is abutted against the shift lever 30. Thus, one side of the shift lever 30 can bear only one acting force, that is, one side bears the driving force from the key 40, and the other side bears the resistance from the latch 20, so that the one-side structure of the shift lever 30 is less prone to bending deformation or breakage, and the working reliability and the service life of the locking mechanism are improved. Of course, in other embodiments, the position where the key abuts against the shift lever and the position where the latch abuts against the shift lever may be located on the same side of the rotating shaft.

Referring to fig. 1 and 5, in an embodiment, the base 10 has a mounting cavity 10a, and an assembling opening 10b corresponding to the shift lever 30, the assembling opening 10b is communicated with the mounting cavity 10a, the rotating shaft 11 is disposed in the mounting cavity 10a, and a limiting protrusion 12 is disposed on an inner wall of the mounting cavity 10 a; the shift lever 30 is rotatably mounted on the rotating shaft 11 and abuts against the side of the limit protrusion 12 away from the fitting opening 10 b. In this way, the limit protrusion 12 can prevent the shift lever 30 from slipping off along the axis of the rotating shaft 11 from the rotating shaft 11 after being mounted, thereby improving the operational reliability of the locking mechanism. Of course, in other embodiments, a limiting convex portion may be disposed on the rotating shaft, and the shift lever is rotatably mounted on the rotating shaft and abuts against a side of the limiting convex portion away from the assembling through hole.

Referring to fig. 1 and 2, in an embodiment, the first direction and the second direction are intersected. Specifically, in the embodiment, the first direction and the second direction are perpendicular and nearly perpendicular to each other. In this way, the direction of displacement is changed by the shift lever 30, that is, the displacement of the key 40 in the first direction is converted into the displacement of the latch 20 in the second direction, so that the width of the locking mechanism in the second direction can be reduced, and the product is favorably designed in a thin manner. Of course, in other embodiments, the first direction and the second direction may be arranged in parallel.

Referring to fig. 2 and 3, in an embodiment, the shift lever 30 is provided with a force-bearing inclined surface 31, the force-bearing inclined surface 31 is disposed to intersect with the second direction, and the key 40 is provided with a driving inclined surface 41 corresponding to the force-bearing inclined surface 31. Specifically, in this embodiment, the included angle between the driving inclined surface 41 and the second direction is set to range from 20 ° to 70 °, for example, 30 °, 45 °, or 50 °. So, can make atress inclined plane 31 and drive inclined plane 41 keep the butt relation to can enough make button 40 more smooth-going when pressing, can also avoid pressing the problem that the in-process appears the space at button 40, and then improve the feel that button 40 pressed, and promote the quality of product.

In this embodiment, the push button 40 is configured as a rotary body having the first direction as an axis, the push button 40 includes a cylindrical portion 42 and a conical portion 43, and the driving inclined surface 41 is formed on the conical surface of the conical portion 43. Therefore, the key 40 can slide more smoothly, and the driving inclined surface 41 can still keep the abutting relation with the force-bearing inclined surface 31 after the key 40 rotates around the axis of the key by any angle. The rotary body-shaped key 40 has a simple structure and low manufacturing cost. Of course, in other embodiments, the key may include a rectangular prism and a triangular prism connected with each other, and the driving slopes are formed on the sides of the triangular prism.

In this embodiment, the shift lever 30 has two flanges 32 corresponding to the key 40, and the force-receiving slant 31 is formed between the two flanges 32. Thus, the structural strength of the shift lever 30 can be improved through the two flanges 32, so that the shift lever 30 is less prone to deformation or breakage, and the working reliability and the service life of the locking mechanism are improved.

In this embodiment, the axis of the key 40 passes through the rotating shaft 11. Therefore, the arrangement of parts on the locking mechanism can be more compact, the width dimension of the locking mechanism in the second direction is further reduced, and the thin design is facilitated. Of course, in other embodiments, the axis of the key may not intersect with the rotation axis.

Referring to fig. 2 and 3, in an embodiment, the latch 20 is provided with a limiting groove 21 corresponding to the shift lever 30, and an end of the shift lever 30 is movably inserted into the limiting groove 21. Therefore, the problem that the shift lever 30 is separated from the latch 20 due to deformation and the like can be avoided, that is, the shift lever 30 is kept in the abutting relation with the latch 20, and the working stability and the smoothness of the locking mechanism are further improved. Of course, in other embodiments, the end of the shift lever may abut against the outer side surface of the latch.

In this embodiment, the limiting groove 21 has two opposite groove walls distributed in the first direction, a guiding inclined surface 211 is provided at a side edge of the groove wall close to the rotation axis 11 of the shift lever 30, and the guiding inclined surface 211 is inclined and extended in a direction away from the shift lever 30 in a direction toward the rotation axis 11 of the shift lever 30. Therefore, the problem that the shifting lever 30 and the limiting groove 21 are mutually abraded in the rotating process of the shifting lever 30 can be avoided, and the service life of the locking mechanism is prolonged.

Referring to fig. 2 and 3, in an embodiment, the locking mechanism further includes an elastic member 50 disposed between the latch 20 and the base 10, and the elastic member 50 is configured to make the latch 20 have a tendency to slide from the retracted position to the extended position. Specifically, the elastic member 50 may be one of a compression spring, a torsion spring, a spring plate, an elastic rubber body, and an elastic silicone body. In this way, the elastic element 50 is used to elastically reset the latch 20, that is, when the driving force applied to the shift lever 30 by the button 40 is released, the elastic element 50 drives the latch 20 to pop up again to the extended position, thereby facilitating the user to lock the function body 70. Certainly, in other embodiments, the elastic member may not be provided, the latch is further provided with a pressing portion and a positioning convex portion, the base is provided with an avoiding hole corresponding to the pressing portion, and is provided with a positioning groove corresponding to the positioning convex portion, when the latch is in the extended position, the positioning convex portion is clamped in the positioning groove, and the pressing portion is located in the avoiding hole; when the clamping tongue is in the retraction position, the positioning convex part is separated from the positioning groove, and the pressing part extends out of the avoiding hole and is used for abutting and pushing.

Referring to fig. 2 and 5, in an embodiment, the latch 20 has a protruding pillar 22 corresponding to the elastic element 50, the base 10 has a mounting groove 10c corresponding to the elastic element 50, one end of the elastic element 50 is sleeved on the protruding pillar 22, and the other end of the elastic element 50 abuts against the mounting groove 10 c. Specifically, in the present embodiment, the elastic member 50 is a compression spring. Thus, the position of the elastic member 50 can be well defined by the mounting groove 10c and the stud 22, so that the elastic member 50 can work more smoothly and stably. Of course, in other embodiments, the elastic member may be configured as an elastic rubber body or an elastic silicone body, the latch has a first groove corresponding to the elastic member, the base has a second groove corresponding to the elastic member, and one end of the elastic member abuts against the first groove and the other end abuts against the second groove.

Referring to fig. 3, in an embodiment, the latch 20 further has a slide rail 23, the base 10 has a slide slot 10d corresponding to the slide rail 23, and the slide slot 10d extends along the second direction. Therefore, the sliding guide function of the latch 20 is realized by the cooperation of the sliding rail 23 and the sliding groove 10d, and the sliding of the latch 20 can be smoother and more stable. Of course, in other embodiments, the base may be provided with an adaptive mounting hole corresponding to the latch tongue, and the latch tongue is adaptively slid in the mounting hole.
