Technical Field

[0002] The present application relates to the technical field of wearable devices, and in particular to a wearable device, and a watch strap and a watch dial that can be used in the wearable device. Background Art

[0003] Wearable devices generally refer to miniature electronic devices that can be worn on the body for activities, and primarily include smart watches and smart bracelets. Smart watches and smart bracelets can be used independently or as portable accessories for mobile devices.

[0004] Wearable devices mainly include a dial and a strap. The connection between the dial and the strap is mostly fixed or difficult to disassemble quickly, which brings inconvenience to the replacement of the strap.

[0005] Summary of the Invention

[0006] The present application provides a wearable device, a watch strap and a watch dial that can be used in the wearable device. The purpose is to provide a structure that allows for quick detachment of the watch strap.

[0007] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0008] In a first aspect, the present application provides a watch strap that can be applied to a wearable device, for example, the wearable device can be a watch or a bracelet.

[0009] The watch strap provided in the present application may include a strap body and a quick-release strap structure arranged on the strap body, and the quick-release strap structure is used to connect to the dial; the quick-release strap structure includes a movable part and a button; the movable part can move along a first direction so that the movable part is connected to the dial; the button can move along a second direction intersecting with the first direction, the movable part includes a first matching part, and the button includes a second matching part, and the first matching part is further away from the part of the movable part used to connect to the dial than the second matching part; when the button moves, the second matching part pushes the first matching part, and the movable part can move in a direction opposite to the first direction to disengage from the dial.

[0010] For example, a slot is provided on the dial for the movable member to enter and exit. When the watch strap and the dial need to be connected, the movable member can be inserted into the slot to achieve the connection between the watch strap and the dial. When the connected watch strap and the dial need to be detached, a button can be pressed, which transmits a force to the second mating portion of the movable member that mates with the first mating portion. Under this force, the movable member can move away from the slot, so that the movable member exits the slot, and the watch strap and the dial are detached. This quick-release watch strap structure has a simple structure and is easy to operate, and can achieve quick disassembly and assembly of the watch strap.

[0011] In one possible implementation, the interface where the first mating portion contacts the second mating portion is a first inclined surface; the movable part has a first side and a second side facing back to back, and the first side is closer to the button than the second side; the movable part has a first end connected to the dial, and a second end opposite to the first end; in the direction from the first end to the second end, the first inclined surface is inclined from the second side to the first side.

[0012] In this example, the interface between the button and the movable part is designed as an inclined surface. When the button pushes the movable part, the thrust generates a component force on the inclined surface that moves away from the slot. This component force can be used to move the movable part away from the slot, thereby causing the movable part to exit the slot.

[0013] In one achievable manner, the inclination angle of the inclined surface is less than or equal to 45°.

[0014] This allows the movable member to be quickly withdrawn from the slot.

[0015] In one practicable manner, the watchband quick-release structure further includes: a first limiting structure; the first limiting structure is used to limit the distance that the movable part moves along the first direction.

[0016] By utilizing the limiting structure, the moving distance of the movable member can be limited, so that the movable member can be more accurately extended into the slot or accurately withdrawn from the slot.

[0017] In one achievable method, the first limiting structure includes a limiting groove, which is arranged on the movable part, and the second matching part of the button is located in the limiting groove; the limiting groove includes a first wall surface and a second wall surface facing each other, the second wall surface is farther away from the first end of the movable part than the first wall surface, and the second wall surface is a first inclined surface.

[0018] In this implementation, a limiting groove is provided on the movable member, the second matching portion of the key is extended into the limiting groove, and the movement distance of the movable member is limited by the matching of the second matching portion and the movable member.

[0019] In addition, one of the walls of the limit groove directly serves as the fitting interface between the movable part and the button, making the structure of the device more compact and meeting the requirements of miniaturized device design.

[0020] In one possible implementation, the movable member is made of an elastic material, for example, a memory alloy material can be selected to make the movable member.

[0021] In one possible implementation, the watchband quick-release structure further includes an elastic member; the elastic member is connected to the movable member, and the elastic member is used to provide elastic force for the movable member to move in the first direction.

[0022] When the movable member is inserted into the slot of the connecting member, the elastic force exerted by the elastic member on the movable member can improve the connection reliability between the watch strap and the dial.

[0023] In one possible implementation, the watch strap quick-release structure also includes a second limiting structure; the movable part is connected to the dial, and the second limiting structure is used to limit the movement of the strap body along a third direction and a fourth direction, the third direction and the fourth direction are perpendicular to each other and are both perpendicular to the second direction.

[0024] In the example of the present application, when the movable part extends into the card slot, the card slot can be used to limit the movement of the strap along its thickness direction (such as the Z direction), and the above-mentioned second limiting structure can be used to limit the movement of the strap along its length direction (such as the X direction) and along its width direction (such as the Y direction). In this way, multi-directional locking of the dial and the strap is achieved.

[0025] In one practicable manner, the watchband quick-release structure further includes a third limiting structure; the third limiting structure is used to limit the distance that the button moves along the second direction.

[0026] In one possible implementation, the watch strap also includes a mounting shell, which is detachably mounted on the end of the strap body, the button portion and the movable part are arranged in the mounting shell, the surface of the mounting shell facing the dial has a through-hole, and the part of the movable part passes through the through-hole; the mounting shell has a first side surface and a second side surface back to back, the first side surface of the mounting shell is closer to the skin than the second side surface, and the button portion extends through the first side surface of the mounting shell into the mounting shell.

[0027] The detachable structure is integrated into the installation shell to form a module, and the module is detachably installed on the belt body, so that the module can be easily disassembled or replaced.

[0028] In one possible implementation, a slide groove is provided on one of the button and the mounting shell, and a slider sliding in the slide groove is provided on the other. The extension direction of the slide groove is parallel to the second direction, and the slide groove and the slider cooperate to limit the distance that the button moves along the second direction.

[0029] The movement distance of the button is limited by the combination of the slide groove and the slider.

[0030] In one possible implementation, the mounting shell includes a main body and a cover body, the main body and the cover body are detachably connected, the button part and the movable part are arranged in the mounting space formed by the main body and the cover body, the main body is provided with a mounting hole, and the button part extends into the mounting space through the mounting hole.

[0031] In one practicable manner, the watchband quick-release structure further includes: an anti-drop structure for preventing the button from sliding out of the first side; the anti-drop structure includes an extension portion arranged on the button, and the cover body has a support platform for supporting the extension portion.

[0032] Since the button is arranged on the back of the watch strap, the extension portion on the button cooperates with the support platform on the mounting shell, thereby preventing the button from falling out of the mounting shell.

[0033] In one possible implementation, the end surface of the movable member for connecting with the dial is a second inclined surface.

[0034] In one possible implementation, the movable member has a first side and a second side facing back to back, the first side being closer to the button than the second side; the movable member has a first end connected to the dial, and a second end opposite to the first end; in the direction from the first end to the second end, the second inclined surface is inclined from the first side to the second side.

[0035] In one possible implementation, the end surface of the key away from the movable member protrudes from the outer wall surface of the mounting shell.

[0036] In one possible implementation, the first moving direction of the movable element is perpendicular to the second moving direction of the key, and the first direction is perpendicular to the thickness direction of the dial.

[0037] In one achievable method, the first moving direction of the movable part is perpendicular to the second moving direction of the key, and the first direction is not perpendicular to the thickness direction of the dial, that is, the first direction is tilted relative to the thickness direction of the dial.

[0038] In a second aspect, the present application provides a wearable device, which includes a dial and a strap in any of the above-mentioned implementations, wherein the strap is connected to a movable part.

[0039] Since the wearable device includes the watch strap in the above-mentioned implementation manner, the detachable structure provided on the watch strap can realize the quick disassembly and assembly of the watch strap and the dial, so that the user can quickly replace the watch strap or the dial according to needs.

[0040] In one possible implementation, a slot is provided on the dial, and the movable member that moves along the first direction can be inserted into the slot, so that the movable member is connected to the dial.

[0041] The present application utilizes a card slot to cooperate with a movable part, has a simple structure, and is easy to implement.

[0042] In one possible implementation, the watch strap also includes a mounting shell, which is detachably mounted on the end of the strap body. A receiving groove for inserting the mounting shell is provided on the watch dial, and a first opening is provided on the side of the receiving groove close to the skin. The mounting shell can be placed in the receiving groove through the first opening.

[0043] Since an opening is provided on the side of the mounting shell close to the skin, when installing the watch strap, the watch strap can slide from bottom to top through the opening into the accommodating groove, so that the movable part is inserted into the slot to realize the connection between the watch strap and the dial.

[0044] In one possible implementation, the watch strap quick-release structure also includes a second limiting structure; the movable part is connected to the dial, and the second limiting structure is used to limit the movement of the strap body along a third direction and a fourth direction, the third direction and the fourth direction are perpendicular to each other and are both perpendicular to the second direction.

[0045] The slot can be matched with the movable part to limit the movement of the strap relative to the dial along the thickness direction of the strap (such as the Z direction). The above-mentioned second limiting structure can be used to limit the movement of the strap along its length direction (such as the X direction) and along its width direction (such as the Y direction). In this way, multi-directional locking of the dial and the dial is achieved.

[0046] In one achievable method, the accommodating groove has a first wall surface and a second wall surface facing each other, and the first wall surface and the second wall surface are arranged in a direction consistent with the width direction of the belt body; the second limiting structure includes a limiting groove and a limiting protrusion, one of the limiting groove and the limiting protrusion is arranged on the mounting shell, and the other is arranged on the first wall surface and the second wall surface.

[0047] When the watch strap is inserted into the accommodating groove, the cooperation between the limiting groove and the limiting protrusion can prevent the watch strap from moving along its width direction and also prevent the watch strap from moving along its length direction, thus achieving two-way limitation.

[0048] In one feasible method, the accommodating groove has a second opening facing the belt body, and a bottom opposite to the second opening; from the second opening of the accommodating groove to the bottom of the accommodating groove, the groove width of the accommodating groove gradually increases, and the width dimension of the mounting shell gradually increases to form a second limiting structure.

[0049] Since the accommodating groove for inserting the watch strap is set to a structure with a variable groove width, that is, the structure of the accommodating groove is such as a dovetail groove structure, it can not only prevent the watch strap from moving along its width direction, but also prevent the watch strap from moving along its length direction, thereby achieving two-way limitation.

[0050] On the third aspect, the present application provides a quick-release structure for a watch strap, which is used to connect a watch dial and a watch strap. The quick-release structure for the watch strap can be set on the watch strap or on the watch dial.

[0051] The watch strap quick-release structure includes a mounting shell, a movable part and a button; wherein the movable part can move along a first direction so that the movable part is connected to the watch strap or the dial; the button can move along a second direction intersecting with the first direction, the movable part includes a first matching part, and the button includes a second matching part, and the first matching part is further away from the part of the movable part used to connect with the dial or the watch strap than the second matching part; when the button moves, the second matching part pushes the first matching part, and the movable part can move in a direction opposite to the first direction to detach from the watch dial or the watch strap.

[0052] In one possible implementation, the interface where the first mating portion contacts the second mating portion is a first inclined surface; the movable part has a first side and a second side facing back to back, and the first side is closer to the button than the second side; the movable part has a first end connected to the dial, and a second end opposite to the first end; in the direction from the first end to the second end, the first inclined surface is inclined from the second side to the first side.

[0053] When the key pushes the movable part, the thrust generates a component force on the inclined surface away from the card slot, and the component force can be used to move the movable part away from the card slot, so that the movable part is withdrawn from the card slot.

[0054] In one practicable manner, the watchband quick-release structure further includes a first limiting structure; the first limiting structure is used to limit the distance that the movable part moves along the first direction.

[0055] By utilizing the limiting structure, the moving distance of the movable member can be limited, so that the movable member can be more accurately extended into the slot or accurately withdrawn from the slot.

[0056] In one achievable method, the first limiting structure includes a limiting groove, which is arranged on the movable part, and the second matching part of the button is located in the limiting groove; the limiting groove includes a first wall surface and a second wall surface facing each other, the second wall surface is farther away from the first end of the movable part than the first wall surface, and the second wall surface is a first inclined surface.

[0057] In one possible implementation, the watchband quick-release structure further includes an elastic member; the elastic member is connected to the movable member, and the elastic member is used to provide elastic force for the movable member to move in the first direction.

[0058] In one possible implementation, the watch strap quick-release structure also includes a second limiting structure; the movable part is connected to the dial, and the second limiting structure is used to limit the movement of the strap body along a third direction and a fourth direction, the third direction and the fourth direction are perpendicular to each other and are both perpendicular to the second direction.

[0059] This allows for multi-directional locking of the dial and strap.

[0060] In one practicable manner, the watchband quick-release structure further includes a third limiting structure; the third limiting structure is used to limit the distance that the button moves along the second direction.

[0061] In one possible implementation, a slide groove is provided on one of the button and the mounting shell, and a slider sliding in the slide groove is provided on the other. The extension direction of the slide groove is parallel to the second direction, and the slide groove and the slider cooperate to limit the distance that the button moves along the second direction.

[0062] In one possible implementation, the mounting shell includes a main body and a cover body, the main body and the cover body are detachably connected, the button part and the movable part are arranged in the mounting space formed by the main body and the cover body, the main body is provided with a mounting hole, and the button part extends into the mounting space through the mounting hole.

[0063] In one practicable manner, the watchband quick-release structure further includes: an anti-drop structure for preventing the button from sliding out of the first side; the anti-drop structure includes an extension portion arranged on the button, and the cover body has a support platform for supporting the extension portion.

[0064] In a fourth aspect, the present application provides a dial that can be used in a wearable device, for example, the wearable device can be a watch or a bracelet.

[0065] The watch dial provided in the present application may include a watch body, and a quick-release structure for a watch strap arranged on the watch body, wherein the quick-release structure for the watch strap is used to connect the watch strap; the quick-release structure for the watch strap includes a movable part and a button; the movable part can move along a first direction so that the movable part is connected to the watch strap; the button can move along a second direction intersecting with the first direction, the movable part includes a first matching part, and the button includes a second matching part, and the first matching part is further away from the part of the movable part used to connect to the watch strap than the second matching part; when the button moves, the second matching part pushes the first matching part, and the movable part can move in a direction opposite to the first direction to detach from the watch strap.

[0066] In the example of this application, the watch strap quick-release structure is set on the dial. For example, a slot for the movable part to enter and exit can be set on the watch strap; if the watch strap needs to be connected to the dial, the movable part can be inserted into the slot; if the connected watch strap and dial need to be disassembled, a button can be pressed, and the button transfers the force to the second mating part of the movable part that cooperates with the first mating part. Under this force, the movable part can move away from the slot, so that the movable part withdraws from the slot, thereby realizing the disassembly of the watch strap and the dial.

[0067] In one possible implementation, the interface where the first mating portion contacts the second mating portion is a first inclined surface; the movable part has a first side and a second side facing back to back, and the first side is closer to the button than the second side; the movable part has a first end connected to the dial, and a second end opposite to the first end; in the direction from the first end to the second end, the first inclined surface is inclined from the second side to the first side.

[0068] In this example, the interface between the button and the movable part is designed as an inclined surface. When the button pushes the movable part, the thrust generates a component force on the inclined surface that moves away from the slot. This component force can be used to move the movable part away from the slot, thereby causing the movable part to exit the slot.

[0069] In one achievable manner, the inclination angle of the inclined surface is less than or equal to 45°.

[0070] This allows the movable member to be quickly withdrawn from the slot.

[0071] In one practicable manner, the watchband quick-release structure further includes: a first limiting structure; the first limiting structure is used to limit the distance that the movable part moves along the first direction.

[0072] By utilizing the limiting structure, the moving distance of the movable member can be limited, so that the movable member can be more accurately extended into the slot or accurately withdrawn from the slot.

[0073] In one achievable method, the first limiting structure includes a limiting groove, which is arranged on the movable part, and the second matching part of the button is located in the limiting groove; the limiting groove includes a first wall surface and a second wall surface facing each other, the second wall surface is farther away from the first end of the movable part than the first wall surface, and the second wall surface is a first inclined surface.

[0074] In this implementation, a limiting groove is provided on the movable member, the second matching portion of the key is extended into the limiting groove, and the movement distance of the movable member is limited by the matching of the second matching portion and the movable member.

[0075] In addition, one of the walls of the limit groove directly serves as the fitting interface between the movable part and the button, making the structure of the device more compact and meeting the requirements of miniaturized device design.

[0076] In one possible implementation, the watchband quick-release structure further includes an elastic member; the elastic member is connected to the movable member, and the elastic member is used to provide elastic force for the movable member to move in the first direction.

[0077] When the movable member is inserted into the slot of the connecting member, the elastic force exerted by the elastic member on the movable member can improve the connection reliability between the watch strap and the dial.

[0078] In one possible implementation, the watch strap quick-release structure also includes: a second limiting structure; the movable part is connected to the watch strap, and the second limiting structure is used to limit the movement of the watch body along a third direction and a fourth direction, the third direction and the fourth direction are perpendicular to each other and are both perpendicular to the second direction.

[0079] In the example of the present application, when the movable part extends into the card slot, the card slot can be used to limit the movement of the strap along its thickness direction (such as the Z direction), and the above-mentioned second limiting structure can be used to limit the movement of the strap along its length direction (such as the X direction) and along its width direction (such as the Y direction). In this way, multi-directional locking of the dials is achieved.

[0080] In one possible implementation, the watchband quick-release structure further includes: a third limiting structure; the third limiting structure is used to limit the distance that the button moves along the thickness direction of the watch body.

[0081] In one possible implementation, a mounting cavity is formed in the watch body, the button portion and the movable part are arranged in the mounting cavity, a through-hole is provided on the surface of the watch body facing the watch strap, and the portion of the movable part passes through the through-hole; the dial includes a display surface and a back surface facing back to the display surface, and the button portion extends through the back surface into the mounting cavity.

[0082] The space inside the watch body is used to accommodate the detachable structure.

[0083] In one possible implementation, a slide groove is provided on one of the button and the watch body, and a slider sliding in the slide groove is provided on the other. The extension direction of the slide groove is parallel to the thickness direction of the watch body. The slide groove and the slider cooperate to limit the distance that the button moves along the thickness direction of the watch body.

[0084] For example, a sliding groove provided on the button can be used to cooperate with a slider provided on the watch body to limit the movement distance of the button.

[0086] Since the button is arranged on the back of the dial, the extension portion on the button cooperates with the support platform on the mounting shell to prevent the button from falling out of the dial.

[0087] In one possible implementation, the end surface of the button away from the movable member is flush with the back surface of the watch body.

[0088] In the example of this application, since the detachable structure is set in the dial, the user can hold the strap with one hand and press the button with the other hand during operation, so that the end face of the button away from the movable part is flush with the back of the watch body, which will not cause difficulty in operation; and since the button is set on the back of the dial, it can also improve wearing comfort.

[0089] In one possible implementation, the end surface of the movable member for connecting with the watchband is a second inclined surface.

[0090] In one possible implementation, the movable member has a first side and a second side facing back to back, the first side being closer to the button than the second side; the movable member has a first end connected to the dial, and a second end opposite to the first end; in the direction from the first end to the second end, the second inclined surface is inclined from the second side toward the first side.

[0091] In a fifth aspect, the present application provides a wearable device, which includes a watch strap and a watch dial in any of the above-mentioned implementation methods, and the watch strap is connected to a movable part.

[0092] Since the wearable device includes the dial in the above implementation, the dial is provided with a quick-release structure, which can be used to quickly disassemble and assemble the strap and the dial, so that the user can quickly replace the strap or the dial according to needs.

[0096] When installing the watch strap, the watch strap can slide from bottom to top through the opening and into the accommodating groove to achieve the connection between the watch strap and the dial.

[0097] In one achievable method, the watch strap quick-release structure also includes: a second limiting structure; the movable part is connected to the watch strap, and the second limiting structure is used to limit the movement of the watch strap along a third direction and a fourth direction, the third direction and the fourth direction are perpendicular to each other and are both perpendicular to the second direction.

[0098] In this way, the movement of the strap can be limited in multiple directions, thereby improving the reliability of the connection between the strap and the dial.

[0099] In one possible implementation, the accommodating groove has a first wall surface and a second wall surface facing each other, and the first wall surface and the second wall surface are arranged in a direction consistent with the width direction of the strap body; the second limiting structure includes a limiting groove and a limiting protrusion, one of the limiting groove and the limiting protrusion is set on the strap, and the other is set on the first wall surface and the second wall surface.

[0145] The present invention provides a wearable device, such as a smart bracelet or smart watch, which can be worn on the wrist and can display time, record time, report time, provide message notifications, detect exercise, monitor heart rate, and detect blood oxygen levels.

[0146] The wearable device may include a band body and a watch body. The band body is used to wrap around the user's wrist to enable the wearable device to be worn, and the watch body is used for display.

[0147] As shown in Figure 1, a structural diagram of a wearable device is shown. The wearable device includes a watch face 100, a first watch strap 201, a second watch strap 202, and a connecting structure 30. The watch face 100 is connected between the first watch strap 201 and the second watch strap 202. The first watch strap 201 and the second watch strap 202 can be connected by the connecting structure 30, so that the first watch strap 201, the watch face 100, and the second watch strap 202 form a closed loop to be wrapped around the wrist.

[0148] In order to meet the changing needs of users, the dial and the strap can be detachably connected. For example, the dial and the strap can be connected using a quick-release strap structure, so that users can quickly remove the strap and replace the required strap or dial.

[0149] Figure 2 is a partial structural diagram of a wearable device given in an embodiment of the present application, and Figure 3 is an exploded view of Figure 2, which includes a watch strap quick-release structure 40, which is arranged at the connection between the watch strap body 20 and the watch dial body 10.

[0150] In the example of the present application, the material of the band body 20 includes but is not limited to metal, plastic, etc. A space is formed in the watch body 10, and electronic components or other structural parts are arranged in the space.

[0151] As shown in Figure 3 , the watchband quick-release structure 40 includes a slot 401, a movable member 402, and a button 403. The movable member 402 and the button 403 cooperate to form a locking member. One of the slot 401 and the locking member is located on the strap body 20, while the other is located on the watch body 10. For example, in the example shown in Figure 3 , the slot 401 is located on the strap body 20, while the locking member, including the movable member 402 and the button 403, is located on the watch body 10.

[0152] FIG4 briefly illustrates the structure of the watch strap quick-release structure 40 of the present application and the assembly and disassembly principle.

[0153] As shown in FIG4 , the movable member 402 can move along a first direction (direction P1 as shown in FIG4 ), for example, the first direction can be the extension direction of the strap, so that the movable member 402 can enter and exit the slot 401. As shown in FIG4 (a) and (b), when the strap and the watch body need to be connected, the structural member providing the slot 401 can be brought into proximity with the movable member 402, and the end of the movable member 402 can be inserted into the slot 401, thereby achieving a snap connection between the strap and the watch body.

[0154] As shown in FIG4 , the button 403 can move along a second direction intersecting the first direction P1. For example, as shown in FIG4 (a), the button 403 can move along a direction L1 perpendicular to the extension direction P1 of the strap, and the direction L1 can be parallel to the thickness direction of the strap. As shown in FIG4 (c) and (d), the button 403 moving toward the movable member 402 moves along the direction L1 as shown in FIG4 (c), which can drive the movable member 402 to move away from the slot 401. The movable member 402 moves along the direction P2 opposite to the direction P1 as shown in FIG4 (c), causing the movable member 402 to withdraw from the slot 401, thereby achieving separation of the strap and the watch body as shown in FIG4 (d).

[0155] In order to enable the movable button 403 to drive the movable part 402 to move in a direction away from the card slot 401, in some implementations, as shown in Figure 4, the movable part 402 includes a first matching portion 4021 that matches with the button 403, and the button 403 includes a second matching portion 4031 that matches with the movable part 402. The first matching portion 4021 of the movable part 402 is farther away from the card slot 401 than the second matching portion 4031 of the button 403; that is, the first matching portion 4021 is farther away from the part of the movable part 402 used to extend into the card slot 401 than the second matching portion 4031.

[0156] In this way, by pressing the button 403, the button 403 can transmit the force to the first matching part 4021 through the second matching part 4031. Under this force, the movable part 402 including the first matching part 4021 can move away from the slot 401, so that the movable part 402 exits the slot 401.

[0157] As shown in FIG. 4 and FIG. 5 , the interface between the first matching portion 4021 and the second matching portion 4031 may be an inclined surface, such as an inclined plane.

[0158] The interface between the first mating portion 4021 and the second mating portion 4031 is an inclined plane, which can be understood as follows: as shown in FIG6 , the movable member 402 has a first side and a second side facing back to back, the first side being closer to the button 403 than the second side, the movable member 402 having a first end for entering and exiting the card slot 401, and a second end opposite the first end, with the inclined plane tilted from the second side toward the first side in the direction from the first end to the second end. When the movable member 402 needs to be withdrawn from the card slot 401, as shown in FIG6 , a thrust F can be applied to the button 403, generating a thrust f at the interface between the first mating portion 4021 of the movable member 402 and the second mating portion 4031 of the button 403. This thrust f generates a force f1 that pushes the movable member 402 to move in the direction P2, thereby causing the movable member 402 to move in the direction P2 and exit the card slot 401.

[0159] In some examples, as shown in FIG6 , the inclination angle α of the inclined plane can be less than or equal to 45°. For example, it can be equal to 45°, or it can be equal to 40°, or it can be equal to 30°. In this way, when the button 403 is pushed, the movable member 402 can respond quickly and quickly withdraw from the slot 401.

[0160] In some examples, as shown in FIG6 , a limiting groove 4022 can be provided on the movable member 402, with the second mating portion 4031 of the button 403 located within the limiting groove 4022. The portion of the movable member 402 located in the limiting groove 4022, facing away from the button 403, serves as the first mating portion 4021. This saves space and makes the device structure more compact. For example, when the button 403 moves along the thickness direction of the strap, as shown in FIG7 , it does not occupy the thickness dimension of the strap or watch body.

[0161] In some other examples, as shown in FIG. 5 , a protrusion may be formed on a side of the movable member 402 close to the button 403 , and the protrusion forms the first matching portion 4021 .

[0162] In other examples, the structures of the first matching portion 4021 and the second matching portion 4031 may also exist in other forms.

[0163] After the strap is separated from the watch body using the quick-release structure, the movable part 402 needs to return to its initial position, as shown in (c) and (d) of FIG. 4 , i.e., the movable part 402 needs to move along the P1 direction toward the card slot so as to engage with the card slot again.

[0164] In some embodiments, the movable member 402 may be made of an elastic material, for example, a memory alloy material.

[0165] In other embodiments, as shown in FIG6 , an elastic member 404 may be used, connected to the movable member 402, to provide an elastic force for the movable member 402 to move toward the slot 401. Then, when the movable member 402 is withdrawn from the slot 401 and the pushing force F on the button 403 is removed, the movable member 402 can move to the left under the elastic force of the elastic member 404 and return to its initial position.

[0166] The watchband quick-release mechanism of the present application may also include a limiting structure for limiting the distance that the movable member 402 can move along a first direction (e.g., along the direction in which the strap extends). This limiting structure allows for precise control of the movement of the movable member 402, allowing it to precisely enter and exit the slot 401, thereby improving the reliability and stability of the quick release between the strap and the watch body.

[0167] As shown in Figures 7 and 8, Figure 7 is a partial three-dimensional structural diagram of the wearable device of the present application, and Figure 8 is a structural diagram taken along the AA section shown in Figure 7. As shown in Figure 8, the limiting structure for limiting the movement distance of the movable member 402 may include a limiting groove 4022 provided on the movable member 402, and the second matching portion 4031 of the button 403 is located in the limiting groove 4022.

[0168] 9 shows an exploded view of the button 403 being removed from the limiting groove 4022. The limiting groove 4022 includes a first wall and a second wall facing each other, the second wall being farther away from the slot 401 than the first wall, and the second wall being an inclined plane.

[0169] The limiting structure shown in FIG. 9 utilizes the cooperation between the button 403 and the limiting slot 4022 to limit the moving distance of the movable member 402 .

[0170] Furthermore, a wall surface (such as the second wall surface) of the limiting groove 4022 is used as the interface for the movable part 402 and the button 403 to fit together, thereby making the structure of the entire device more compact and meeting the design requirements for miniaturization of the device.

[0171] As shown in Figure 9 , in this embodiment, movable member 402, button 403, and elastic member 404 are disposed on watch body 10, and slot 401 is disposed at the end of strap 20. The direction of movement of button 403 is perpendicular to the thickness of the watch body, and the direction of movement of movable member 402 is perpendicular to the thickness of the watch body, for example, parallel to the extension direction of the strap.

[0172] In some structures, as shown in FIG. 10 , a connector 50 may be provided at the end of the belt body 20 , and the card slot 401 is provided on the connector 50 .

[0173] In some optional materials, the belt body 20 can be made of leather, metal, etc., and the connecting piece 50 can be made of metal. The connecting piece 50 is fixedly connected to the belt body 20.

[0174] As shown in Figures 11 and 12, Figure 11 shows a structural diagram of a watch body according to an embodiment of the present application, and Figure 12 is a partial structural diagram of the BB cross-sectional view of Figure 11. In conjunction with Figures 11 and 12, the watch body 10 is provided with a receiving groove 103 for inserting the end of the belt body 20 shown in Figure 10. A mounting cavity 101 is formed within the watch body 10. A portion of the button 43, a portion of the movable member 402, and an elastic member 404 are disposed within the mounting cavity 401. The watch body 10 is provided with a through-hole 102, which connects the mounting cavity 101 and the receiving groove 103. A portion of the movable member 402 extends through the through-hole 102 into the receiving groove 103, enabling it to engage with the latching slot 401.

[0175] In the examples of Figures 11 and 12, the watch body 10 is used as a carrier of the movable part 402, the button 403 and the elastic part 404, and parts of the movable part 402, the elastic part 404 and the button 403 are hidden inside the watch body 10, thereby improving the appearance of the entire device.

[0176] One end of the elastic member 404 may be connected to the movable member 402, and the other end may be connected to the watch body 10. In some examples, a space for arranging the elastic member 404 may be formed between the movable member 402 and the watch body 10. The elastic member 404 is arranged in the space, with one end of the elastic member 404 abutting against the movable member 402 and the other end abutting against the watch body 10.

[0177] Continuing with Figure 12, the watch body 10 also includes a cavity 104 for the movement of the button 403. For example, when the button 403 is pressed, it can be inserted into the cavity 104. This cavity 104 fully utilizes the space within the watch body 10, allowing the button 403 to move without increasing the thickness of the watch body.

[0178] In the example of this application, a limiting structure for limiting the moving distance of the button 403 may also be included. For example, as shown in Figure 12, when the button 403 moves along the L1 direction (for example, along the thickness direction of the watch body), the moving distance of the button 403 needs to be limited to accurately push the movable part 402 to move.

[0179] There are many ways to implement the limiting structure for limiting the moving distance of the button 403.

[0180] For example, as shown in Figure 12, a slide groove 4032 is provided on the button 403, and a slider 105 is provided on the watch body 10 to slide in the slide groove 4032. The extension direction of the slide groove 4032 is parallel to the thickness direction of the watch body. The slider 105 and the slide groove 4032 cooperate to limit the moving distance of the button.

[0181] For another example, the slide groove 4032 may be provided on the watch body 10 , and the slider 105 may be provided on the button 403 .

[0182] In some examples, as shown in FIG12 , the watch body 10 includes a display surface and a back surface facing away from the display surface, and a portion of the button 403 extends through the back surface into the watch body.

[0183] In some structures, the movable member 402 extends into the slot 401 , as shown in FIG12 , and the end surface of the button 403 away from the movable member 402 is flush with the back surface.

[0184] Since the card slot 401 of the example of the present application is provided on the strap 20 and the button 403 is provided on the watch body 10, when the user needs to remove the strap 20, the left hand can pinch the strap 20 and the right hand thumb can press the button 403, instead of performing two actions with the same hand. Therefore, as shown in FIG12 , the end surface of the button 403 away from the movable part 402 can be flush with the back surface of the watch body 20. Since the two hands control different structures respectively, the operation is less difficult. Therefore, the button 403 does not need to be provided with a protruding configuration, and the user can easily control the button 403.

[0185] Since the button 403 is arranged on the back of the watch body 10, the back of the watch body 10 needs to contact the skin, and the end surface of the button 403 away from the movable part 402 is flush with the back, which can also improve wearing comfort and improve the appearance.

[0186] In addition, since the button 403 is located on the back of the watch body, an anti-drop structure can be provided in the wearable device to prevent the button 403 from falling. Figures 13 and 14 exemplify one of the anti-drop structures. Figure 13 shows a three-dimensional view of the button 403, and Figure 14 shows the connection between the button 403 and the watch body 10. The button 403 has an extension 4033, and the watch body 10 is provided with a support platform 106 for supporting the extension 4033. The extension 4033 is supported on the support platform 106 to prevent the button 403 from falling downward (along the L2 direction in Figure 14).

[0187] In the wearable device of the present application, when the movable member 402 extends into the slot 401, connecting the strap 20 and the watch body 10, the slot 401 can restrict the strap 20 from moving along the second direction (e.g., along the thickness direction of the strap). However, the strap 20 may move along other third or fourth directions, making it impossible to lock the strap 20 and the watch body 10. For example, the strap 20 may move along the extension direction of the strap or along the width direction of the strap.

[0188] As shown in Figures 15 and 16, Figure 15 shows an exploded view of the watch body 10 and the strap 20, while Figure 16 shows a detailed view of the connection between the strap and the watch body. As shown in Figure 15, the watch body 10 has a receiving slot 103 for inserting the end of the strap 20. As shown in Figures 15 and 16, the receiving slot 103 has a second opening facing the strap 20 and a bottom opposite the second opening. As shown in Figure 16, the width of the receiving slot 103 (as shown in dimension d in Figure 16) gradually increases from the second opening to the bottom of the slot. This resulting slot structure can be referred to as a dovetail slot structure. As shown in Figure 17, once the strap 20 is inserted into the receiving slot 103, it is prevented from moving in the S direction (i.e., the width of the strap) as shown in Figure 17. Furthermore, because the width of the receiving slot 103 gradually decreases from the second opening to the bottom, the strap 20 within the slot is also prevented from moving in the T direction (i.e., the extension direction of the strap) as shown in Figure 17. Based on this structure, the belt body and the watch body can be locked from multiple directions to improve the connection reliability.

[0189] Refer to Figures 18 and 19. Figure 18 shows the structure of the watch body, while Figure 19 shows an exploded view of the watch body and strap. To connect the watch body 10 and strap 20, the receiving groove 103 in the watch body 10 also has a first opening, located on the same side as the back of the watch body. When installing the strap 20, the strap 20 can slide through the first opening and into the receiving groove 103 in the M direction as shown in Figure 19. The movable member is inserted into the latching slot, achieving a snap connection between the strap and the watch body.

[0190] In order to improve user experience, as shown in FIG19 , the end surface of the movable member 402 for inserting into the card slot 401 is an inclined surface.

[0191] The end face of the movable part 402 for inserting into the card slot 401 is an inclined surface, which can be understood as follows: the movable part 402 has a first side and a second side back to back, and the first side is closer to the button 403 than the second side; the movable part 402 has a first end for entering and exiting the card slot 401, and a second end opposite to the first end; in the direction from the first end to the second end, the inclined surface is inclined from the second side to the first side.

[0192] In this way, when the user moves the belt body 20 from bottom to top (such as the M direction in Figure 19), the movable member 402 can be smoothly inserted into the card slot 401 along the inclined surface.

[0193] Furthermore, when the movable member 402 is inserted into the card slot 401 , due to the inclined surface, the inclined surface structure can also play a limiting role, preventing the belt body 20 from moving in the opposite direction of the M direction as shown in FIG. 19 , thereby preventing the movable member 402 from sliding out of the card slot 401 .

[0194] In the above example, the slot 401 of the watchband quick-release mechanism is provided on the watchband, and the movable member 402 and button 403 are provided on the dial. The following provides some other examples, in which the slot 401 is provided on the dial, and the movable member 402 and button 403 are provided on the watchband. The specific implementation structure is described below.

[0195] As shown in FIG20 , FIG20 is a partial structural diagram of a wearable device. In this example, the movable part and the button are integrated into a module 60, and the module 60 is provided on the band 20. A slot for cooperating with the movable part in the module 60 is provided on the watch body 10.

[0196] FIG21 is an exploded view of the module 60 in FIG20. The module 60 includes a mounting shell, which may include a main body 601 and a cover 602. The main body 601 and the cover 602 are buckled together to form a mounting space 605 therein.

[0197] In some examples, the main body 601 and the cover 602 may be fixedly connected by fasteners 604 , or the main body 601 and the cover 602 may be fixedly connected by welding.

[0198] The fixedly connected main body 601 and cover 602 can be fixedly connected to the belt body 20 by a fastener 603 as shown in FIG. 21 , so as to facilitate the disassembly and assembly of the module 60 or the replacement of component structures in the module.

[0199] At least part of the movable member 402 , the elastic member 404 and the button 403 may be disposed within the installation space 605 .

[0200] Figure 22 is a structural diagram of a module 60 according to an example of the present application, and Figure 23 is a structural diagram taken along line CC of Figure 22. As shown in Figure 23, the main body 601 and the cover 602 are fastened together, forming an installation space 605 therein. The main body 601 is provided with a through-hole 606 communicating with the installation space 605. The elastic member 404 is disposed within the installation space 605. A portion of the movable member 402 extends through the through-hole 606 to the outside of the module to engage with the slot. A portion of the button 403 extends into the installation space 605 and cooperates with the movable member 402 for use.

[0201] This embodiment can refer to Figure 4 of the above example, the movable part 402 includes a first matching portion 4021 that matches with the button 403, and the button 403 includes a second matching portion 4031 that matches with the movable part 402. The first matching portion 4021 of the movable part 402 is farther away from the card slot 4011 than the second matching portion 4031 of the button 403; that is, the first matching portion 4021 is farther away from the part of the movable part 402 used to extend into the card slot 401 than the second matching portion 4031.

[0202] When the button 403 is pressed, the button 403 can transmit the force to the first matching portion 4021 through the second matching portion 4031. Under the force, the movable part 402 including the first matching portion 4021 can move away from the card slot 401, so that the movable part 402 exits the card slot 401.

[0203] The interface where the movable part 402 contacts the button 403 is an inclined plane. The moving button 403 pushes the movable part 402, causing the movable part 402 to move away from the slot, thereby exiting the slot and separating the strap body from the watch body.

[0204] The inclination angle α of the inclined plane can be less than or equal to 45°. For example, it can be equal to 45°, or it can be equal to 40°, or it can be equal to 30°. In this way, when the button 403 is pushed, the movable member 402 can respond quickly and quickly withdraw from the slot 401.

[0205] As shown in Figure 24, Figure 24 is a schematic diagram of two different connection relationships between the movable part 402 and the button 403 in the examples of this application. In the two different examples, a limiting groove 4022 is provided on the movable part 402, and part of the button 403 extends into the limiting groove 4022. The limiting groove 4022 can limit the moving distance of the movable part 402. The above examples have explained the limitation principle and will not be repeated here.

[0206] Since the button 403 has a moving stroke, for example, in this example, the button 403 is set on the belt body, it needs to have a moving stroke in the thickness direction of the belt body, and further, it is necessary to reserve a moving space for the button 403 on the structural member.

[0207] For example, in the example of FIG24(b), the movable member 402 and the button 403 are arranged on the watch body 10, which can fully utilize the space on the watch body 10. That is, a cavity 104 can be provided on the watch body 20, and the movable button 403 can extend into the cavity 104. In the example of FIG24(a), the movable member 402 and the button 403 are both arranged on the belt body. The belt body is relatively thin and compact. Using a structure similar to the example of FIG24(b) may increase the thickness of the belt body. In the example of the present application, as shown in FIG24(a), an extension portion 4023 can be provided on the side of the movable member 402 near the button 403. The extension portion 4023 is in contact with a portion of the button 403 to ensure the movement of the button 403.

[0208] Returning to Figure 23, in the example of this application, a limiting structure for limiting the moving distance of the button 403 may also be included. For example, a slide groove 4032 is provided on the button 403, and a slider 6021 is provided on the cover body 602, which is slidably arranged in the slide groove 4032. The extension direction of the slide groove 4032 can be parallel to the thickness direction of the belt body. The slider 6021 and the slide groove 4032 cooperate to limit the moving distance of the button.

[0209] For another example, the slide groove may be provided on the cover body, and the slider may be provided on the button.

[0210] In some examples, the button 403 is located on the back of the strap, i.e., on the side closest to the skin. Therefore, when the user needs to remove the strap 20, they need not only hold the strap with their left hand but also press the button 403. To facilitate user operation, as shown in FIG25 , the end surface of the button 403 away from the movable member 402 can protrude from the surface of the mounting shell 60A.

[0211] In addition, since the button 403 is disposed on the back of the strap, an anti-drop structure may be provided in the wearable device to prevent the button 403 from falling. For example, a support platform may be provided on the mounting shell 60A, and a portion of the button 403 may be provided on the support platform. Alternatively, as shown in FIG26 , which exemplifies one anti-drop structure, a support platform may be provided on the cover 602 of the mounting shell. The support platform may be a slider 6021 in the limiting structure, and a portion of the button 403, such as the extension 4033, may be provided on the slider 6021 to prevent the button 403 from falling downward.

[0212] From the perspective of assembly process, the button 403 can pass through the hole on the main body 601 and extend into the main body 601, and then the cover body 602 is installed, and the slider 6021 of the cover body 602 as shown in Figure 26 is extended into the slide groove 4032 of the button 403, and then the cover body 602 is fixedly connected to the main body 601 using fasteners.

[0213] When the movable member 402 extends into the slot 401, connecting the strap 20 and the watch body 10, the slot 401 can limit the movement of the strap 20 along the thickness direction of the strap. However, the strap 20 may move along the extension direction of the strap and may also move along the width direction of the strap.

[0214] As shown in Figures 27 and 28, Figure 27 shows the structure of the watch body 10, while Figure 28 shows the structure of the module installed in the belt body. As shown in Figure 26, the watch body 10 is provided with a receiving groove 103 for inserting the end of the belt body 20. The receiving groove 103 has a first wall surface and a second wall surface facing each other, and the first wall surface and the second wall surface are arranged in a direction consistent with the width direction of the belt body.

[0215] As shown in FIG27 , limiting grooves 101 may be provided on both the first wall surface and the second wall surface. As shown in FIG28 , limiting protrusions 607 that can be inserted into the limiting grooves 101 are provided on the outer wall surface of the module.

[0216] In some other examples, limiting grooves may be provided on the outer wall surface of the module, and limiting protrusions may be provided on the first wall surface and the second wall surface.

[0217] In this example, once the strap and watch body are engaged, the engagement of the limiting protrusion 607 with the limiting groove 101 prevents the strap from moving relative to the watch body along the width direction of the strap (the S direction in FIG. 28 ) and along the extension direction of the strap (the T direction in FIG. 28 ). This allows the strap and watch body to be locked in place from multiple angles.

[0218] Returning to Figure 27 , to connect the watch body 10 and the strap 20, the receiving groove 103 in the watch body 10 also has a second opening. This first opening is located on the same side as the back of the watch body. When installing the strap 20, the strap 20 can slide through the first opening and into the receiving groove 103 in the direction M as shown in Figure 27 . The movable member is inserted into the engaging groove, achieving a snap connection between the strap and the watch body.

[0219] In order to improve user experience, as shown in FIG29 , the end surface of the movable part 402 for inserting into the card slot 401 is an inclined surface.

[0220] The end face of the movable part 402 for inserting into the card slot 401 is an inclined surface, which can be understood as follows: the movable part 402 has a first side and a second side back to back, and the first side is closer to the button 403 than the second side; the movable part 402 has a first end for entering and exiting the card slot 401, and a second end opposite to the first end; in the direction from the first end to the second end, the inclined surface is inclined from the second side to the first side.

[0221] In this way, when the user moves the belt body 20 from bottom to top (such as the M direction in Figure 29), the movable member 402 can be smoothly inserted into the card slot 401 along the inclined surface.

[0222] Furthermore, when the movable member 402 is inserted into the slot 401 , due to the inclined surface, the inclined surface structure can also play a limiting role, preventing the belt body 20 from moving in the opposite direction of the M direction as shown in FIG. 29 , thereby preventing the movable member 402 from sliding out of the slot 401 .

[0223] When the locking member including the movable member 402 and the button 403 is set on the watch strap, there are many situations for the movement directions of the movable member 402 and the button 403, and two ways are given as examples below.

[0224] Figure 30 illustrates a cross-sectional view of a portion of the structure of a wearable device. In this embodiment, the movable member 402 can move along the P direction, the button 403 can move along the L direction, and the thickness direction of the dial is H. The movement direction P of the movable member 402 is perpendicular to the movement direction L of the button 403, while the movement direction P of the movable member 402 is not perpendicular to the thickness direction H of the dial. For example, the P direction and the H direction form an angle greater than 90 degrees.

[0225] Figure 31 illustrates a cross-sectional view of a partial structure of another wearable device. In this embodiment, the movable member 402 can move along the P direction, the button 403 can move along the L direction, and the thickness direction of the dial is H. The movement direction P of the movable member 402 is perpendicular to the movement direction L of the button 403, and the movement direction P of the movable member 402 is perpendicular to the thickness direction H of the dial.

[0226] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0227] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
