[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0038] The core of the present invention is to provide a quick-release module, which can facilitate the disassembly and assembly of a watch strap. Another core of the present invention is to provide a watch strap and a wrist-worn device including the quick-release module, which are convenient for disassembly and assembly of the watch strap.

[0039] It should be noted that when an element is referred to as being "fixed" to another element, it may be directly on the other element or there may be an element in the middle. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an element in the middle at the same time. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] The quick release module provided by the present invention is applied to a wrist-worn device. In a specific embodiment, the quick release module includes a mounting shell, an elastic member 13 and a hook 14. The elastic member 13 and the hook 14 are arranged in the mounting shell.

[0042] The middle portion of the hook 14 is pivotally connected to the mounting housing. Figure 2 and Figure 3 As shown, the mounting shell is pivotally connected with a pivot shaft 15, and the middle part of the hook 14 is fixed on the pivot shaft 15. The elastic member 13 is specifically a torsion spring and is abutted between the pivot shaft 15 and the mounting shell. The elastic member 13 can provide an elastic reset force to drive the pivot shaft 15 and the hook 14 to rotate.

[0043] Both ends of the hook 14 extend out of the mounting shell in a free state, and the two ends of the hook 14 constitute a clamping end 141 and a triggering end 142, respectively. The free state refers to the state in which the quick-release module is not subjected to other external forces except gravity and atmospheric pressure. Of course, when the hook 14 is rotated to change the quick-release module from the free state to other states, the clamping end 141 and the triggering end 142 may be retracted into the mounting shell. In addition, since the clamping end 141 and the triggering end 142 are rotatable, the openings on the mounting shell for the corresponding extension of the clamping end 141 and the triggering end 142 should reserve space for the clamping end 141 and the triggering end 142 to rotate. The clamping end 141 is used for detachably clamping the watch case 3, and the elastic reset force of the elastic member 13 makes the clamping end 141 have a tendency to move along the clamping direction, that is, the direction in which the clamping force increases when the clamping end 141 is clamped to the watch case 3.

[0044] Correspondingly, in the wrist-worn device using the quick-release module, a watch case 3 and a watch strap are included. The main control components of the wrist-worn device are arranged in the watch case 3, and the strap body and the quick-release module constitute the watch strap, so that the strap body can be quickly released or quickly installed with the watch case 3 through the quick-release module. A card slot 32 is provided on the side of the watch case 3, and the card slot 32 can be removably engaged with the card slot 31 by the card connection end 141. When the card slot 32 is engaged with the card connection end 141, the elastic reset force of the elastic member 13 causes the card slot 32 to be clamped by the card connection end 141, and the trigger end 142 is located outside the watch case 3. The trigger end 142 is used to receive an external force outside the card slot 32 to drive the hook 14 to rotate, so that the engagement between the card slot 32 and the card connection end 141 is released, and the strap body 4 can be removed.

[0045] When it is necessary to assemble or disassemble the watch strap, simply press the trigger end 142 to rotate the hook 14 and then engage or disengage the watch case 3. The operation is convenient and the watch strap can be quickly disassembled from the watch case 3. Since most of the structure of the hook 14, the elastic member 13, and the pivot shaft 15 are all built into the mounting shell, the mounting shell can protect the hook 14, the elastic member 13, and the pivot shaft 15. The quick-release module is connected to other structures or components in the wrist-worn device as a whole, and the assembly efficiency is relatively high.

[0046] Furthermore, two opposite ends of the mounting shell are respectively provided with a docking structure for docking the belt body 4 and a plugging structure for plugging into the watch case 3, and the plugging structure is arranged obliquely relative to the docking direction defined by the docking structure. Figure 3 As shown, during the docking process of the belt body 4, the belt body 4 moves along the docking direction defined by the docking structure (based on Figure 3 The left direction in the lower position) approaches the docking structure to dock with the docking structure.

[0047] Accordingly, in a wrist-worn device using the quick-release module, Figure 3As shown, a slot 31 is correspondingly provided on the side of the watch case 3 to adaptably engage with the plug-in structure on the mounting shell. In the engaged state, the plug-in structure is obliquely inserted into the slot 31. After being plugged in place, the plug-in structure is positioned by the slot wall of the slot 31, and the slot wall of the slot 31 preferably corresponds to the surface of the mounting shell.

[0048] When wearing, Figure 4 and Figure 6 As shown, the bottom surface 33 of the watch case contacts the skin, and the docking direction defined by the docking structure is substantially parallel to the bottom surface 33 of the watch case. The mounting shell will be affected by the belt body 4 in the opposite direction of the docking direction (i.e., corresponding to Figure 3 The pulling force F1 is roughly parallel to the bottom surface 33 of the case, and due to the oblique insertion of the mounting shell and the slot 31, the pressure F2 of the slot wall of the slot 31 on the mounting shell has a component force F21 in the opposite direction to F1, which can effectively prevent the mounting shell from falling out of the slot 31 in a direction parallel to the bottom surface 33 of the case, thereby improving the reliability of the connection.

[0049] For further information, please refer to Figure 4 The card connection end 141 extends out of the mounting shell through the plug-in structure in a free state.

[0050] Correspondingly, in the wrist-worn device using the quick-release module, the card slot 32 is connected to the slot 31, and the snap-in end 141 enters the card slot 32 through the slot 31. During the assembly process, it is only necessary to align the plug-in structure with the slot 31 for plugging, and release the pressure on the trigger end 142 after the plug-in is in place to complete the plug-in. There is no need to align the snap-in end 141 and the card slot 32 while aligning the plug-in structure and the slot 31. In addition, based on the positional relationship between the snap-in terminal 141 and the plug-in structure and the structural setting of the snap-in terminal 141 extending out of the plug-in structure, during the process of the plug-in structure being plugged into the slot 31, if the trigger terminal 142 is not pressed and the plug-in structure is directly plugged toward the slot 31, interference will occur between the snap-in terminal 141 and the slot 31. Therefore, during the plug-in process, it is necessary to keep pressing the trigger terminal 142 so that the snap-in terminal 141 does not protrude from the plug-in structure until it is plugged in place and the snap-in terminal 141 is aligned with the slot 32. Then, the force of the trigger terminal 142 is released, and the snap-in terminal 141 is reset to extend out of the mounting shell and engage with the slot 32.

[0051] For further information, please refer to Fig.10The mounting shell includes a first shell 11 and a second shell 12, which are fixedly connected and form a mounting cavity 17 therebetween, and the elastic member 13 and the hook 14 are arranged in the mounting cavity 17. The snap-on end 141 extends from the first shell through hole on the first shell 11, and the trigger end 142 extends from the gap between the second shell 12 and the first shell 11. During the assembly process, the elastic member 13, the pivot shaft 15 and the hook 14 are placed in the first shell 11, and the snap-on end 141 of the hook 14 extends from the first shell through hole, and then the second shell 12 is covered to the first shell 11, so that the trigger end 142 of the hook 14 is located at the gap between the first shell 11 and the second shell 12. After the second shell 12 is covered, the trigger end 142 is naturally located outside the mounting shell, and then the first shell 11 and the second shell 12 are fixed by screws, and the hook 14, the first shell 11 and the second shell 12 are convenient to assemble, and then the quick release module 1 can be assembled to the belt body 4 as a whole. In the wrist-worn device using the quick-release module, the first shell 11 and the second shell 12 can be arranged in sequence along a direction close to the skin.

[0052] For further information, please refer to Figure 7 , the docking structure includes an outer cover 2, and the belt body 4 is directly docked on the outer cover 2, and the belt body 4 is fixedly connected by the outer cover 2 and the mounting shell. Optionally, a connection groove plugged into the outer cover 2 is provided on the belt body 4, and the extension direction of the connection groove is the docking direction, so that the belt body 4 and the outer cover 2 are plugged and fixed along the docking direction, and the docking direction is consistent with the extension direction of the belt body when it is unfolded and laid flat. The upper part of the mounting shell is plugged and fixed in the reinforcement groove of the outer cover 2, and the first shell 11 and the second shell 12 both have partial structures located in the reinforcement groove, then the reinforcement groove can reinforce the connection between the first shell 11 and the second shell 12, and can effectively prevent the first shell 11 and the second shell 12 from separating. In addition, after the mounting shell is plugged into the reinforcement groove, the first shell 11 is fixed to the outer cover 2 with screws. In addition, the ends of the first shell 11 and the second shell 12 opposite to the end connected to the outer cover 2 constitute a plug-in structure. In addition, the engaging end 141 and the triggering end 142 are exposed outside the outer cover 2 , so that the outer cover 2 will not affect the user's control over the rotation of the hook 14 .

[0053] Furthermore, an elastic button 16 is sleeved on the trigger end 142 , which is beneficial to increase the pressing area and facilitate the pressing control of the trigger end 142 .

[0054] Accordingly, in the wrist-worn device using the quick-release module, in the snap-on state, a closed cavity is preferably formed between the outer cover 2, the button 16 and the case 3 to enclose the mounting shell and the hook 14, such as Figure 8 and Fig. 9 As shown, after snapping in, the mounting shell will not be exposed from the wrist-worn device, which is beneficial to improving the integrity of the appearance of the wrist-worn device.

[0055] The quick release module provided in this embodiment is assembled as follows: the elastic member 13 and the hook 14 are assembled on the first shell 11, and the first shell 11 and the second shell 12 are assembled together and fixed with screws to form a quick release module 1; the quick release module 1 is fixed on the outer cover 2 by screwing.

[0056] In addition, the present invention further provides a watch strap, which includes a quick release module, which can be specifically the quick release module provided in the above embodiment, and the beneficial effects can be referred to the above embodiment accordingly. The watch strap also includes a belt body 4 connected to the quick release module. The structures of other parts of the watch strap can be referred to the prior art, and will not be repeated herein.

[0057] In addition, the present invention also provides a wrist-worn device including the above-mentioned strap, and the beneficial effects can be referred to the above embodiments. Among them, the main control component of the wrist-worn device is arranged in the watch case 3, and the watch case 3 is connected to the strap body 4 via a quick release module. The structures of other parts of the wrist-worn device can be referred to the prior art, and will not be repeated in this article.

[0058] Furthermore, in the quick-release module, the trigger end 142 extends from one side of the mounting shell close to the bottom surface 33 of the watch case 3 in the snap-on state, the trigger end 142 and the push end 141 are located on the same side of the bottom surface 33 of the watch case, and the trigger end 142 does not protrude from the bottom surface 33 of the watch case 3. Therefore, in the worn state, the trigger end 142 is blocked between the mounting shell and the skin and does not come into direct contact with the skin, which can effectively prevent the trigger end 142 from being accidentally triggered in the worn state.

[0059] Furthermore, if Figure 3 As shown, a slot 31 is correspondingly provided on the side of the watch case 3, and the slot 31 extends obliquely relative to the bottom surface 33 of the watch case 3, that is, the slot 31 gradually tilts and approaches the bottom surface 3 of the watch case 3 from the bottom of the slot to the notch. Preferably, the docking direction defined by the docking structure is parallel to the bottom shell 33 of the watch band, and accordingly, in the clamping state, the slot 31 is also inclined relative to the docking direction. The bottom surface 33 of the watch case is the surface of the watch case 3 that directly contacts the skin in the wearing state. In the clamping state, the plug-in structure is obliquely inserted into the slot 31, and after being plugged in place, the mounting shell is positioned by the slot wall of the slot 31, and the slot wall of the slot 31 is preferably correspondingly fitted with the surface of the mounting shell. In the wearing state, compared with the slot bottom of the slot 31, the notch of the slot 31 is closer to the skin, and accordingly, one end of the docking quick-release module on the belt body 4 can fit the skin more closely.

[0060] Wherein, optionally, Figure 3As shown, on the watch case 3, the card slot 32 for carding the card connection end 141 is perpendicular to the extension direction of the slot 31 for plugging with the plug structure, and the two are connected to form an L-shaped slot. The card slot 32 and the slot 31 are arranged in sequence along the direction close to the bottom surface 33 of the watch case, and the pivot axis 15 between the hook 14 and the mounting shell is perpendicular to the docking direction defined by the docking structure. The card connection end 141 extends out of the mounting shell through the plug-in structure in a free state. During the installation process, the trigger end 142 is pressed, and the mounting shell is inserted into the slot 31. When the mounting shell abuts against the slot 31 in the plug-in direction, it is plugged into place. The trigger end 142 is released, and the card connection between the card connection end 141 and the card slot 32 can be realized. In the card connection state, the pivot axis 15 is parallel to the bottom surface 33 of the watch case. Alternatively, in other embodiments, the card slot 32 and the slot 31 can also be connected to form a T-shaped slot. Alternatively, in other embodiments, the card slot 32 and the slot 31 are arranged in sequence along the direction away from the bottom surface 33 of the watch case.

[0061] During the assembly process of the wrist-worn device provided in this embodiment, the quick-release module 1 moves toward the slot 31, the button 16 is pressed, the hook 14 rotates, and the installation shell is obliquely inserted into the slot 31. After being inserted into place, the button 16 is released, and the clamping end 141 is driven to hook the clamping slot 32 through the reset movement of the elastic member 13, so that the strap 4 is not easy to fall off the watch case 3; during the disassembly process of the strap 4 and the watch case 3, the button 16 is pressed, the hook 14 overcomes the elastic force of the elastic member 13 and rotates to release the clamping slot 32, the installation shell is taken out of the slot, and the strap 4 can be removed from the watch case 3.

[0062] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0063] The wrist-worn device, watch strap and quick-release module provided by the present invention are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
