The invention provides a watchband assembly for a wearable device, in particular a watch, a bracelet, a belt, a shoulder strap of a satchel or a handbag, or the like.

In an embodiment of the present invention, please refer to fig. 1 to 4 in combination, a watch band assembly includes:

a band 10;

the two sliding fasteners 20 are arranged along the width direction of the watchband 10 and are connected with the watchband 10 in a sliding manner, and the sliding fasteners 20 are used for being clamped with the clamping part 62 on the equipment main body 60;

the elastic resetting piece 30 is connected with the two sliding clamping pieces 20; and the number of the first and second groups,

a pushing member 40 disposed between the two sliding pieces 20, wherein the pushing member 40 has two inclined surfaces 411 distributed along the width direction of the watch band 10, and the inclined surfaces 411 abut against the sliding pieces 20; the pusher 40 is able to move along the length of the bracelet 10 to move the two sliding jaws 20 towards and away from each other.

Specifically, the band 10 refers to an elongated band, for example, in the case of a wristwatch, the length direction of the band 10 refers to the direction around the wrist, and the width direction of the band 10 refers to the direction along the arm.

The slide fastener 20 is connected with the watch band 10 in a sliding manner, specifically, as shown in fig. 5, a sliding groove 11 can be arranged on the watch band 10 for the slide fastener 20 to be matched in a sliding manner; alternatively, the band 10 is not provided with the slide groove 11. In this manner, to achieve the guiding, a guide bar may be provided along the sliding path of the slide card 20 to guide the slide card 20.

The sliding card 20 can be engaged with the engaging portion 62 of the device body 60 in various ways, for example, in an embodiment, a slot is provided on the sliding card 20, and a engaging protrusion is provided on the engaging portion 62 and is engaged with the slot. In one embodiment, the sliding member 20 has a locking protrusion 22, and the locking portion 62 has a locking groove 621 (fig. 14). In one embodiment, the sliding member 20 and the engaging portion 62 are provided with hooks, and the two hooks are engaged with each other.

The shape of the slide fastener 20 is various, and the slide fastener 20 may be square, cylindrical, triangular, spherical, etc., as long as it is capable of sliding connection with the band 10 and abutting against the pushing member 40.

The elastic restoring member 30 may be a spring, so as to have better elasticity and restore the two sliding clips 20. When the force acting between the two slide latches 20 disappears, the elastic restoring member 30 can move the two slide latches 20 in the direction of approaching each other. In one embodiment, a spring may be located between the two sliding clips 20, and both ends of the spring are respectively connected with the two sliding clips 20. In one embodiment, the springs may be two, one for each slide card member 20, with one end of each spring attached to the wristband and the other end attached to the respective slide card member 20.

The pushing member 40 powers the sliding of the two sliding clips 20, and therefore the two inclined surfaces 411 are provided for the purpose of being able to change the distance between the two sliding clips 20, thereby achieving the sliding of the two sliding clips 20. Pushers 40 may be generally triangular, trapezoidal, or other polygonal configurations, etc. For example, for a trapezoidal pusher 40, the inclined surface 411 is the waist of the trapezoid.

Alternatively, the distance between the two inclined surfaces 411 gradually decreases along the length direction of the band 10 and in the direction away from the device body 60. The separation of the two sliding catches 20 is achieved when the pusher 40 is moved away from the body 60 of the device. For example, both the inclined surfaces 411 are inclined with respect to the width direction of the band 10, or one of the inclined surfaces 411 is inclined with respect to the width direction of the band 10 and the other inclined surface 411 is parallel to the width direction of the band 10. So that pusher 40 can cause the distance between two slide dogs 20 to increase or decrease as pusher 40 moves along the length of band 10. Of course, in other embodiments, the distance between the two inclined surfaces 411 gradually decreases along the length direction of the watch band 10 and the direction approaching the device body 60, and the pushing member 40 moves toward the device body 60 to separate the two sliding jaws 20.

Referring to fig. 9 in conjunction, in particular, the pusher 40 moves in a first direction (the first direction refers to a direction along the length of the bracelet 10 and away from the apparatus body 60) so that the two slide dogs 20 move away from each other; the pushing member 40 moves in the opposite direction of the first direction, and the two sliding clips 20 approach each other under the action of the elastic restoring member 30. In this embodiment, an end of the two inclined surfaces 411 close to each other is a first end, an end of the two inclined surfaces 411 away from each other is a second end, and a direction in which the second end points to the first end is a first direction. When the position of the inclined surface 411 near the first end contacts with the slide fastener 20, it means that the distance between the two slide fasteners 20 is small, so that the engaging portion 62 on the device main body 60 can be tightly engaged between the two slide fasteners 20, and at this time, the engaging portion 62 is in a locked state. When the inclined surface 411 contacts the slide fastener 20 at a position close to the second end, which indicates that the distance between the two slide fasteners 20 is large, the slide fastener 20 is spaced from the engaging portion 62 on the device body 60, so that the engaging portion 62 is released, and the engaging portion 62 is in an unlocked state.

Since the slide fastener 20 is not displaced in the longitudinal direction of the band 10, when the pusher 40 having the two inclined faces 411 is gradually moved in the first direction, the distance between the two inclined faces 411 is gradually increased at the position of contact with the two slide fasteners 20 as the pusher 40 is moved, so that the two slide fasteners 20 are moved in the direction away from each other. When the pushing member 40 moves in the opposite direction of the first direction, the distance between the two inclined surfaces 411 gradually decreases at the position of contact with the two sliding catches 20, so that the two sliding catches 20 move toward each other by the elastic restoring member 30.

In the invention, the two sliding clamping pieces 20 are clamped or separated with the clamping part 62 on the equipment main body 60 by pushing the pushing piece 40 along the length direction of the watchband 10, the back and forth movement of the pushing piece 40 in one direction can be directly converted into the movement of the two sliding clamping pieces 20 without the transmission of other transmission mechanisms, so that the loss in the force conversion process can be reduced, and the movement of the two sliding clamping pieces 20 can be driven by small force; and the arrangement of other structures can be reduced, the whole mechanism is simplified, and the cost is saved.

In the above, the slide fastener 20 and the elastic restoring member 30 may be provided inside the band 10 to reduce the protrusion of the exterior of the band 10. Of course, the band 10 may be formed as a convex hull with the slide fastener element 20 and the resilient return element 30 disposed therein. Alternatively, the slide card member 20 and the elastic restoring member 30 may be directly exposed outside the band 10.

Referring to fig. 5 and fig. 7 again, in order to avoid the deviation of the sliding clip 20 during the sliding process, in an embodiment, the watch band 10 has a sliding groove 11, the sliding clip 20 has a sliding portion 21 and a locking protrusion 22 connected with each other, the sliding portion 21 is in sliding fit with the sliding groove 11, the locking protrusion 22 extends out of the sliding groove 11 and abuts against the inclined surface 411, and the locking protrusion 22 is used for being locked with the locking groove 621 of the locking portion 62. In this embodiment, the protrusion 22 extends out of the sliding slot 11 to facilitate contact with the inclined surface 411, so that the pushing member 40 can slide outside the sliding slot 11 without considering collision with the slot wall of the sliding slot 11, thereby facilitating arrangement of the pushing member 40. Meanwhile, the pushing member 40 is located outside the sliding groove 11, which is equivalent to pressing the sliding portion 21 in the sliding groove 11, so that the sliding portion 21 is prevented from falling out of the sliding groove 11 due to vibration or other reasons. Furthermore, the protrusion 22 extends out of the sliding slot 11 to facilitate the engagement with the engaging slot 621 of the engaging portion 62.

Specifically, the snap projection 22 has a cylindrical shape. The cylindrical snap projection 22 is in line contact with the inclined surface 411, and the contact area of the two is small, so that the friction between the two can be greatly reduced. Correspondingly, the engaging groove 621 of the engaging portion 62 is semicircular. Of course, in other embodiments, the snap protrusions 22 may have other shapes, such as square, triangle, oval, etc., which is not limited herein.

When the elastic resetting piece 30 is reset, the two sliding clips 20 are pulled to approach each other, and at this time, if the pushing piece 40 fails, for example, the pushing piece 40 is displaced, so that the two sliding clips 20 cannot contact the two jamming protrusions 22, the two sliding clips 20 are no longer subjected to the blocking force of the pushing piece 40, so that the elastic resetting piece 30 enables the moving speed to be faster. In order to avoid the two sliding pieces 20 from colliding with each other due to inertia generated by too fast moving speed, and thus the whole mechanism is disabled, in an embodiment, please refer to fig. 6 and 7 in combination, the watch band 10 has a sliding groove 11, and the sliding groove 11 has two sliding sections 111 and a connecting section 112 connecting the two sliding sections 111. One sliding clip 20 is arranged in each sliding section 111, and the sliding clip 20 can abut against the groove wall of the sliding section 111 departing from the connecting section 112 after sliding to a certain position in a direction close to the other sliding clip 20, and the elastic resetting piece 30 is arranged on the connecting section 112. In this embodiment, the slide groove 11 is formed like an i-shape. When the slide fastener 20, i.e. the sliding portion 21, abuts against the groove wall of the sliding section 111 facing away from the connecting section 112, indicating that the distance between the two slide fasteners 20 is the shortest, the engaging portion 62 is engaged by the two slide fasteners 20.

In this embodiment, the connecting section 112 extends in a substantially elongated shape along the width direction of the band 10, and it is conceivable that the connecting section 112 has a width smaller than that of the sliding section 111. The elastic reset piece 30 contacts with the long groove wall of the connecting section 112 or is in small clearance fit with the long groove wall of the connecting section 112, so that the elastic reset piece 30 arranged in the connecting section 112 can be well limited by the connecting section 112, and the elastic limiting piece 30 is prevented from moving along the length direction of the watchband. In addition, the connecting section 112 can guide the elastic limiting member 30, so that the elastic restoring member 30 can deform along the long groove wall of the connecting section 112 when being lengthened or shortened, and the reliability of the whole mechanism in the movement process is ensured.

Referring to fig. 8, 9 and 11, in order to prevent the sliding clip 20 from falling out of the sliding groove 11, in an embodiment, the watch band assembly further includes a pressing piece 50, the pressing piece 50 covers the notch of the sliding groove 11 to limit the sliding portion 21 in the sliding groove 11, the pressing piece 50 is provided with a first clearance hole 51, and the locking protrusion 22 extends out of the first clearance hole 51. Optionally, the first relief opening 51 extends along the width direction of the watch band 10, and the protrusions 22 of the two slide fasteners 20 extend into the same first relief opening 51. By providing the pressing piece 50, the sliding portion 21 can be stopped in the sliding groove 11, and can be prevented from falling out.

The connecting mode of the pressing sheet 50 and the watchband 10 in the embodiment of the invention has various modes, in one embodiment, the pressing sheet 50 and the watchband 10 are adhered through viscose; in one embodiment, the sheeting 50 is snap-fitted to the band 10; in one embodiment, the sheeting 50 is attached to the band 10 by screws. Referring to fig. 5, in an embodiment, the watch band 10 further has a limiting groove 12, the sliding groove 11 is disposed at a bottom of the limiting groove 12, and the pressing piece 50 is clamped in the limiting groove 12. In this embodiment, the shape of the limiting groove 12 is substantially similar to or matches with the shape of the pressing sheet 50, so that the pressing sheet 50 can fit into the limiting groove 12, and thus, the limiting groove 12 can limit the pressing sheet 50. For example, the pressing sheet 50 is oval, and the limiting groove 12 is also oval correspondingly; the pressing sheet 50 is in a strip shape, and the limiting groove 12 is also in a strip shape. Of course, the shape of the limiting groove 12 may not be exactly the same as the pressing sheet 50, as long as the pressing sheet 50 cannot move around. In order to further ensure the stable connection between the pressing piece 50 and the watch band 10, in this embodiment, the pressing piece 50 is also bonded to the bottom of the limiting groove 12.

In one embodiment, the pushing element 40 abuts against a surface of the pressing sheet 50 away from the sliding groove 11, so that the pushing element 40 has a certain limiting effect on the pressing sheet 50, and the pressing sheet 50 is prevented from falling out.

Referring to fig. 4 and 12 again, in an embodiment, the pushing member 40 has a pushing plate 41 and a pushing key 42 connected to each other, the pushing plate 41 has the inclined surface 411, the wristband 10 is provided with a second avoiding hole 1311 through which the pushing key 42 extends, and the pushing key 42 is movably engaged with the second avoiding hole 1311 to be capable of moving along the length direction of the wristband 10. In this embodiment, the push plate 41 may be generally triangular or trapezoidal. The push key 42 is generally cylindrical, elliptical cylindrical, spherical, square, or the like. The push plate 41 is positioned inside the band 10, and only the push key 42 is exposed to the outside for the user to act, so that the exposed part can be reduced, and the influence on the appearance can be reduced. In addition, the second indent 1311 is elongated along the length of the watch band 10 to allow the push button 42 to move in the first direction.

Referring to fig. 5 again, specifically, a receiving cavity 14 is formed in the watch band 10, and the sliding fastener 20, the elastic restoring member 30 and the pushing member 40 are disposed in the receiving cavity 14. Thus, the parts can be prevented from being damaged when colliding with other external objects. The wall of the housing cavity 14 is provided with an insertion opening 15 (as shown in fig. 13), and the insertion opening 15 is used for inserting the engaging portion 62. The engaging portion 62 is movably engaged with the insertion port 15, and when the engaging portion 62 is separated from the slide card 20, the engaging portion 62 can be taken out from the insertion port 15.

In the above, the insertion opening 15 is provided on the side of the band 10 facing the device body 60, and the engagement portion 62 is located on the side of the device body 60 facing the band 10, thereby facilitating the engagement of the two.

Referring to fig. 5, fig. 10 and fig. 12 again, in addition, a third abdicating hole 16 is further formed in the cavity wall of the accommodating cavity 14, the watchband assembly further includes a cover plate 13 detachably connected to the watchband 10, the cover plate 13 covers the third abdicating hole 16, and the cover plate 13 is provided with the second abdicating hole 1311. The cover 13 may be adapted to engage, screw, or plug the strap 10. By providing the detachable cover plate 13, the cover plate 13 can be easily removed to repair the structure inside the accommodating cavity 14.

In one embodiment, the cover plate 13 has a covering section 131 and a limiting section 132 respectively disposed on two opposite sides of the covering section 131, the covering section 131 covers the third relief opening 16, the limiting section 132 is connected to the covering section 131, the limiting section 132 is staggered toward the inside of the accommodating cavity 14 relative to the covering section 131 to form a step therebetween, and the limiting section 132 is abutted against the cavity wall of the accommodating cavity 14. By such arrangement, the cover plate 13 can be prevented from being separated from the third escape position port 16. In addition, because the covering section 131 and the limiting section 132 are staggered to form a step, the outer surface of the covering section 131 and the outer surface of the watchband 10 can be flush, and dust accumulation caused by staggering of the covering section and the limiting section is avoided. In addition, the cover plate 13 may abut against the push plate 41 to prevent the cover plate 13 from moving into the housing cavity 14.

In assembly, as shown in fig. 6 and 7, the slide fastener 20 and the elastic restoring member 30 are first fitted into the slide groove 11. As shown in fig. 8, the pressing piece 50 is further fitted into the stopper groove 12, and the pressing piece 50 is brought into contact with the sliding portion 21 of the slide card 20. As shown in fig. 9, the pushing member 40 is inserted between the protrusions 22 of the two slide clips 20, so that the inclined surface 411 of the pushing member 40 abuts against the side surface of the protrusion 22. As shown in fig. 10, the cover plate 13 is finally covered on the third relief opening 16 of the receiving cavity 14, and the pushing key 42 of the pushing member 40 is exposed to the outside by protruding from the second relief opening 1311 of the cover plate 13.

The present invention further provides a wearable device, which includes a device main body 60 and a watchband assembly, and the specific structure of the watchband assembly refers to the above embodiments, and since the wearable device adopts all technical solutions of all the above embodiments, the wearable device at least has all beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated here. The wearable device can be a watch or a bracelet.

Referring to fig. 14, the device body 60 includes a housing 61 and a latch 62 connected to each other, and the latch 62 has a locked state in which it is latched to the slide latch 20 of the watchband assembly and an unlocked state in which it is separated from the slide latch 20. When the pusher 40 moves in the first direction, the engaging portion 62 is switched from the locked state to the unlocked state. When the pusher 40 moves in the direction opposite to the first direction, the engaging portion 62 is switched from the unlocked state to the locked state. For a wristwatch, the case 61 refers to a portion of the dial.

In one embodiment, the engaging portion 62 is substantially plate-shaped, and two opposite sides of the engaging portion are respectively provided with a locking slot 621, and the locking slot 621 is locked with the locking protrusion 22 on the sliding card member 20. Specifically, the engaging portion 62 is inserted into the receiving cavity 14 from the insertion opening 15, and extends between the two slide fasteners 20 to be engaged by the engaging protrusions 22 of the two slide fasteners 20.

To ensure the strength of the engaging portion 62, in one embodiment, the engaging portion 62 is a metal sheet. The engaging portion 62 may be formed as an insert and integrally injection-molded with the housing 61 of the device body 60, so that the mounting of the engaging portion 62 and the housing 61 is eliminated.

Specifically, when the watch band 10 needs to be detached from the device body 60, the pushing key 42 on the pushing element 40 only needs to be pushed in the first direction, so that the slide fastener 20 contacting with the inclined surface 411 of the pushing element 40 moves outwards (in the direction in which the two slide fasteners 20 are away from each other), so that the slide fastener 20 is disengaged from the engaging portion 62, and at this time, the device body 60 is pulled outwards, so that the engaging portion 62 can be pulled out from the insertion opening 15 on the watch band 10, and the separation of the watch band 10 and the device body 60 is realized. After the two parts are separated, the small parts such as the pushing element 40, the sliding card element 20, the elastic reset element 30, etc. are arranged together with the watch band 10, namely, arranged in the accommodating cavity 14 of the watch band 10 and always assembled with the watch band 10, and the small parts are not scattered along with the separation of the watch band 10 and the device body 60, so that the situation that the small parts are lost can be avoided. In addition, this detachment is achieved by pushing the pushing member 40 without the aid of any external tool, which greatly facilitates detachment of the wristband 10 from the device body 60.

When the watchband 10 and the device body 60 need to be assembled together, the clamping part 62 is firstly inserted into the insertion opening 15 of the watchband 10, and the clamping part 62 extends into the space between the two sliding fasteners 20; then, the pushing member 40 is pushed in the opposite direction of the first direction, so that the two sliding clips 20 approach each other under the action of the elastic restoring member 30 and are clipped into the clipping grooves 621 on the clipping portions 62, thereby realizing clipping. Similarly, when assembling, other external tools are not needed, so that the two can be very conveniently installed.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
