Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0046] With the development of science and technology and the increasing preference of consumers for smart electronic products, smart wrist-worn products have rapidly emerged, such as smart bracelets, which are also constantly updated. Wrist-worn devices generally include a wrist-worn body and a strap. Currently, the connection between the wrist-worn body and the strap on the market is mostly fixed or not easy to disassemble quickly, making it inconvenient to replace the strap.

[0047] In view of this, the present invention provides a wrist-worn device, which may be a watch, a bracelet, etc. However, for ease of description, the wrist-worn device is hereinafter described as a bracelet. Figures 1 to 6 For an embodiment of the wrist-worn device provided by the present invention, please refer to Figures 1 to 6 The wrist-worn device 200 includes a wrist-worn body 201, a strap 202, and a quick-release mechanism 100 of the wrist-worn device. Since the main invention of the present invention lies in the improvement of the quick-release mechanism 100 of the wrist-worn device, the quick-release mechanism 100 of the wrist-worn device will be mainly described below in conjunction with specific drawings.

[0048] See also Figures 1 to 4 The quick release mechanism 100 of a wrist-worn device provided by the present invention comprises a connecting portion 1, a docking portion 2, a snap-fit ​​mechanism (not shown in the drawings), an operating member 4 and a driving mechanism (not shown in the drawings), wherein one of the connecting portion 1 and the docking portion 2 is used to be arranged on a wrist-worn body 201, and the other is used to be arranged on a strap 202. The end of the connecting portion 1 is provided with a snap-fitting slot 11 for inserting a plug-in end 21 of the docking portion 2, and the snap-fitting slot 11 has a first side wall 12 in a first direction; the snap-fitting mechanism comprises a buckle portion 31 and an active buckle 32, and the buckle portion 31 and the active buckle 32 are provided on the wrist-worn body 201. One of them is arranged on the inner side surface of the first side wall 12, and the other is arranged on the plug-in end 21 of the docking part 2. The movable buckle 32 is movably arranged in the first direction, and has a buckling position for buckling with the buckle 31 and a separation position for being separated from the buckle 31. When the movable buckle 32 is in the buckling position, the plug-in end 21 is restricted from being separated from the slot 11. The operating member 4 is movably arranged on the connecting part 1 or the docking part 2. The driving mechanism is arranged between the operating member 4 and the movable buckle 32, and is used for converting the movement stroke of the operating member 4 into the movement of the movable buckle 32 along the first direction.

[0049] In the technical solution provided by the present invention, the action of the operating member 4 is transmitted to the active buckle 32 through the driving mechanism, so that when the active buckle 32 moves to the buckled position, the connection between the connecting part 1 and the docking part 2 is realized, thereby realizing the rapid installation between the wrist-worn body 201 and the strap 202; and, when the active buckle 32 moves to the separated position, the connection part 1 and the docking part 2 are separated, thereby realizing the rapid disassembly between the wrist-worn body 201 and the strap 202.

[0050] It should be noted that the above-mentioned connecting portion 1 and docking portion 2 can be separate components independent of the wrist-worn body 201 and the strap 202, and then be respectively installed on the wrist-worn body 201 and the strap 202 by means of screw fixation, adhesive fixation, snap fixation or adsorption fixation; of course, the above-mentioned connecting portion 1 and docking portion 2 can also be directly formed on the wrist-worn body 201 and the strap 202, for example, the two ends connected to the wrist-worn body 201 and the strap 202; the present design does not impose any restrictions on the corresponding relationship between the connecting portion 1 and the docking portion 2, and the wrist-worn body 201 and the strap 202. For example, as shown in the accompanying drawings of this embodiment, the connecting portion 1 can be set at the end of the wrist-worn body 201, and the docking portion 2 can be set at the end of the strap 202. In addition, the present design does not limit the specific form of the card slot 11. The card slot 11 can be set to a longitudinal shape that is compatible with the cross-sectional shape of the wrist-worn body 201, or it can be set to a shape different from the cross-sectional shape of the wrist-worn body 201, such as a circle or other suitable special shape; but in order to make the card slot 11 just hold the plug-in end 21 of the limit docking part 2, the outer wall contour shape of the plug-in end 21 of the docking part 2 is preferably compatible with the inner groove wall shape of the card slot 11, so as to avoid leaving a large gap between the two, which would cause relative displacement between the strap 202 and the wrist-worn body 201, causing the two to easily loosen and easily generate noise.

[0051] Similarly to the above, the present design also does not limit the corresponding relationship between the buckle 31 and the active buckle 32, and the card slot 11 and the plug-in end 21 of the docking part 2. For example, as shown in the drawings of this embodiment, the buckle 31 is arranged in the card slot 11, and the active buckle 32 is arranged on the plug-in end 21 of the docking part 2. In addition, the buckle 31 and the active buckle 32 can be directly formed on the card slot 11 and the plug-in end 21 of the docking part 2, or can be set as a separate component independent of the card slot 11 and the plug-in end 21 of the docking part 2, and fixed on the card slot 11 and the plug-in end 21 of the docking part 2 by a connection method such as the above.

[0052] The operating member 4 is arranged on the connecting part 1 or the docking part 2. For example, as shown in the drawings of this embodiment, the operating member 4 is arranged on the connecting part 1. In addition, the operating member 4 generally has an insertion end accommodated in the card slot 11 and an operating end exposed outside the connecting part 1, wherein the insertion end is connected to the active buckle 32, and the operating end is used for the user to press, push, pull or rotate. The driving mechanism is arranged between the operating member 4 and the active buckle 32 to transmit the power from the operating member 4 to the active buckle 32, which is more suitable for saving effort or converting the movement direction of the operating member 4 and the active buckle 32 according to different practical applications.

[0053] In view of the above, in this design, the buckle 31 can be set on the inner side of the first side wall 12, and the active buckle 32 can be set on the plug-in end 21; or the active buckle 32 can be set on the inner side of the first side wall 12, and the buckle 31 can be set on the plug-in end 21. The principles of the two schemes are basically the same, but because the inner side of the first side wall 12 is the inner groove wall of the card slot 11, at this time, the installation operation of the active buckle 32 can only be carried out in a semi-enclosed limited space, which is more troublesome. Therefore, in this embodiment, the buckle 31 is mainly set on the inner side of the first side wall 12 as an example for explanation. In this way, the installation operation of the active buckle 32 can be directly performed on the outer wall of the plug-in end 21, which is easier to implement, and therefore more convenient for users to disassemble and replace. Based on this, preferably, the operating member 4 and the driving member 51 can also be set on the plug-in end 21, so that the operating member 4 and the driving member 51 can directly drive the active buckle 32.

[0054] Specifically, the plug-in end 21 of the docking part 2 may include a bottom shell (not shown in the drawings) and a cover plate (not shown in the drawings), the bottom shell is used to accommodate the active buckle 32, the operating member 4 and the driving mechanism, and the cover plate is provided at the opening of the bottom shell to protect the accommodating components in the bottom shell. Among them, at least one end of the active buckle 32 facing the buckle 31 is exposed outside the bottom shell, which is convenient for engaging with the buckle 31; at least the operating end of the operating member 4 is exposed outside the bottom shell, which is convenient for the user to control the activity of the operating member 4 through the operating end. It should be noted that the shapes of the bottom shell and the cover plate are adapted to the active buckle 32 and the driving mechanism at the corresponding positions, so as to limit the active buckle 32 and the driving mechanism in directions unrelated to the realization of the above functions; and the bottom shell is not limited to a whole shell, but can be a spliced ​​body composed of multiple plate materials or rod materials; in addition, the accommodating space in the bottom shell can be divided into multiple independent areas according to actual needs, so as to provide independent installation for the active buckle 32 and the driving mechanism, etc. The bottom shell and the docking portion 2, and the bottom shell and the cover plate can be connected by screwing, bonding, snapping, etc., which will not be described in detail here.

[0055] To achieve the above functions, please refer to Figure 1 , Figure 3 and Figure 6In this embodiment, the driving mechanism includes a driving member 51 and a transmission mechanism (not shown in the drawings), wherein the driving member 51 is movably arranged along the second direction, and the driving member 51 is connected to the end of the movable buckle 32 facing away from the buckle portion 31 by a wedge-shaped surface drive, wherein the first direction and the second direction are arranged crosswise; the transmission mechanism is arranged between the operating member 4 and the driving member 51, and is used to convert the movable stroke of the operating member 4 into the movement of the driving member 51 in the second direction. There are two connecting surfaces abutting each other between the driving member 51 and the movable buckle 32, and any one of the two connecting surfaces can be set as an inclined surface, or both can be set as inclined surfaces, and the inclined surfaces of the two connecting surfaces are adapted to each other. By driving the wedge-shaped surface, the movable directions of the driving member 51 and the movable buckle 32 can be set to be different, that is, they are arranged crosswise, which is more convenient for the flexible arrangement of the driving member 51 and the movable buckle 32. Similarly, the setting of the transmission mechanism can make the moving directions of the operating member 4 and the driving member 51 be set to different directions, so that the quick release mechanism 100 of the wrist-worn device can be set differently according to different actual applications, which is more convenient for users to use.

[0056] In addition, the present design does not limit the specific number of the clamping mechanism, and the clamping mechanism can be set to one or more according to actual needs; and when the clamping mechanism is set to multiple, the multiple clamping mechanisms can be arranged at any position on the card slot 11 or the plug-in end 21. Specifically, in the present embodiment, the card slot 11 has two first side walls 12 in the first direction; the clamping mechanism is correspondingly provided with at least two between the two first side walls 12 and the plug-in end 21, and the movable buckles 32 of the two clamping mechanisms are arranged at intervals along the first direction. The driving member 51 is respectively connected to the movable buckles 32 of the two clamping mechanisms through a wedge-shaped surface driving connection, so that when moving in the second direction, the two movable buckles 32 are driven to move along the first direction. The present design does not limit the shape of the first side wall 12 to only be a straight surface. According to the actual needs of the card slot 11, the first side wall 12 can also be set to be an arc surface or a special shape. The two snap-fitting mechanisms are arranged at opposite positions so that the snap-fitting mechanisms can snap-fit ​​on opposite sides of the slot 11. When the plug-in end 21 applies a force toward one of the first side walls 12 through the snap-fitting mechanism, the direction of the reaction force generated is away from the first side wall 12, that is, toward the other first side wall 12, which can enhance the snap-fitting strength of the other first side wall 12, thereby improving the connection strength between the wrist-worn body 201 and the strap 202.

[0057] In view of the above, when there are multiple clamping mechanisms, the driving member 51 can be set to correspond to the multiple clamping mechanisms to achieve independent driving of each clamping mechanism; however, in order to simplify the overall structure of the quick release mechanism 100 of the wrist-worn device, it is also possible to set a single driving member 51 to drive multiple clamping mechanisms at the same time. Figure 5 and Figure 6 In this embodiment, the driving member 51 is provided with a driving groove 511, and the driving groove 511 has two driving side walls 512 in the first direction; the ends of the two movable buckles 32 away from the buckles are respectively provided with driving protrusions 321 extending toward the driving groove 511, and the two driving side walls 512 are correspondingly connected to the two driving protrusions 321 through wedge surfaces. The setting of the driving groove 511 is convenient for reserving space for the movement of the two movable buckles 32 along the first direction, and also helps to reduce the material used for the driving member 51. It should be noted that the driving member 51 can be optionally arranged in the area between the two active buckles 32, and it is preferred that the wedge-shaped arrangement between the two driving side walls 512 and the two driving protrusions 321 is arranged in the same manner, that is, the inclination and length are arranged to be the same. In this way, the two active buckles 32 can be controlled by the same driving member 51, and the synchronization and consistency of the movement of the two active buckles 32 can be ensured, thereby facilitating the force balance during the installation and disassembly of the strap 202, and avoiding the situation where the active buckle 32 on one side is still stuck in the buckle 31 when the other active buckle 32 is removed, causing inconvenience to the user.

[0058] Based on this, during the installation of the driver 51, it is necessary to ensure that the driver 51 is accurately installed between the two movable buckles 32. Therefore, in this embodiment, a positioning protrusion 71 can be provided on the driver 51 and one of the connecting portion 1 or the docking portion 2 for its movable installation, and the other can be provided with a positioning recess 72 that matches the positioning protrusion 71. For example, when the driver 51 is arranged at the plug-in end 21 of the docking portion 2, a positioning protrusion 71 can be provided on the side of the plug-in end 21 facing the driver 51, and a positioning recess 72 can be provided at the corresponding position of the driver 51. This design does not limit the specific forms of the positioning protrusion 71 and the positioning recess 72, as long as the shapes of the two are matched. Among them, the positioning recess 72 can have two transverse blocking surfaces spaced apart in the first direction, and the positioning protrusion 71 is suitable for the shape of the positioning recess 72, thereby helping to limit the movement of the driving member 51 along the first direction; in addition, the positioning recess 72 can also have two longitudinal blocking surfaces spaced apart in the second direction, and the positioning protrusion 71 is suitable for the shape of the positioning recess 72, thereby limiting the movement of the driving member 51 along the second direction.

[0059] Of course, there can be many specific directions of the transmission mechanism for realizing the above functions. In this embodiment, the transmission mechanism includes a rack portion 521, a beveled tooth portion 522 and a guide portion (not shown in the drawings), wherein the rack portion 521 is arranged on the side of the operating member 4 along the length direction of the operating member 4; the beveled tooth portion 522 is arranged on the driving member 51, and the beveled tooth portion 522 has gear teeth that gradually extend in a second direction along the length direction of the operating member 4, and the gear teeth are meshed with the rack portion 521; the guide portion includes a guide groove 523 extending along the second direction, and a guide protrusion 524, one of which is arranged on the side wall of the driving member 51, and the other is arranged on the connecting portion 1 or the docking portion 2 for the movably mounted driving member 51. For the convenience of description, the length direction of the operating member 4 can be defined as the third direction, the rack portion 521 is, for example, a rack, and the beveled tooth portion 522 is, for example, a bevel gear. When the user drives the rack portion 521 to move linearly along the third direction through the operating member 4, the rack portion 521 begins to mesh with the bevel gear portion 522. Since the gear teeth of the bevel gear portion 522 gradually extend in an inclined manner toward the second direction in the third direction, during the meshing process, the bevel gear portion 522 has a stroke of moving along the third direction and a stroke of moving along the second direction. However, the guide groove 523 is configured to extend along the second direction. When the guide groove 523 and the fixedly installed guide protrusion 524 are matched in a concave-convex manner, the two side walls of the guide groove 523 limit the movement of the bevel gear along the third direction. Therefore, the bevel gear portion 522 can only move along the second direction. At this time, the driving member 51 fixedly connected to the bevel gear portion 522 can also only move along the stroke in the second direction, and then drives the active buckle 32 to move along the first direction through the connection with the wedge-shaped surface of the active buckle 32. Of course, when actually needed, an extension section can be extended along the third direction at one point of the guide groove 523, so that the driving member 51 can be deflected by a certain angle driven by the helical tooth portion 522. It should be noted that the first direction is arranged to intersect with the second direction, and the third direction is arranged to intersect with the second direction. At this time, the first direction and the third direction can be set to be the same or different.

[0060] Furthermore, in this embodiment, the movable buckle 32 can be reset to the engaged position by a reset member 6; the driving member 51 drives the movable buckle 32 to move to the separated position during its movable travel. The movable buckle 32 can be switched between the engaged position and the separated position by the cooperation of the reset member 6 and the driving member 51. Specifically, the reset member 6 can be a separate component independent of the active buckle 32, and is arranged on the side of the active buckle 32 that is opposite to the buckle portion 31. When the driving member 51 does not act on the active buckle 32, so that the active buckle 32 is in the buckled position, the reset member 6 is in the initial relaxed state; when the driving member 51 acts on the active buckle 32, so that the active buckle 32 is in the separated position, the active buckle 32 applies pressure in the direction opposite to the buckle portion 31 to the reset member 6, so that the reset member 6 is deformed under pressure, and then generates a reaction force toward the buckle portion 31 on the active buckle 32. When the driving member 51 cancels the elastic pressure on the active buckle 32, the active buckle 32 is pressed toward the buckle portion 31 for buckling. In addition, when the side of the active buckle 32 that is opposite to the buckle portion 31 directly abuts against the plug-in end 21, the active buckle 32 can be made of an elastic material. At this time, the active buckle 32 itself constitutes a reset member 6. The reset principle is the same as above, which is not repeated here.

[0061] Among them, there can be many specific technical solutions for the reset member 6, including a spring member for example. When, as described above, the connecting portion 1 has two opposite first side walls 12, the two snap-fitting mechanisms are arranged between the two first side walls 12 and the plug-in end 21, and the active snaps 32 of the two snap-fitting mechanisms are arranged at intervals in the first direction, the reset member 6 can be directly arranged in the area between the two active snaps 32, for example, sleeved on the protruding connecting columns of the two active snaps 32. At this time, the reset member 6 simultaneously applies the same and opposite forces to the two active snaps 32, which helps to strengthen the snapping strength between the two active snaps 32 and the corresponding buckle portions 31, and has the advantage of saving consumables.

[0062] In view of the above, the present design does not restrict the specific setting position of the operating member 4, but preferably, in the present embodiment, the operating member 4 is convexly arranged on the outer wall in the width direction of the connecting portion 1. Compared with setting in other positions, for example, the operating member 4 is convexly arranged on the side of the bracelet facing the wrist, which is not only easy to irritate the skin, but also inconvenient to operate, and may also be affected by other actions of the user and cause misoperation, resulting in the detachment between the wrist-worn body 201 and the strap 202; for another example, the operating member 4 is convexly arranged on the side of the bracelet facing away from the wrist, which is easy to hook or scratch foreign objects or users, and is not conducive to aesthetics. The operating member 4 in the present design is convenient for operation and will not interfere with the user.

[0063] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
