Description

[0001] This application claims priority to Chinese Patent Application No. 202311873100.0, filed with the China National Intellectual Property Administration on December 29, 2023 and entitled "WATCH STRAP, WATCH FACE, AND WEARABLE DEVICE", which is incorporated herein by reference in its entirety.TECHNICAL FIELD

[0002] This application relates to the field of wearable device technologies, and in particular, to a wearable device, and a watch strap and a watch face that may be applied to the wearable device.BACKGROUND

[0003] A wearable device is usually a micro electronic device that can be worn on a body to perform an activity, and basically includes a smartwatch and a smart band. The smartwatch and the smart band may be used independently, or may be used as portable accessories of a mobile terminal.

[0004] The wearable device mainly includes a watch face and a watch strap. The watch face is usually connected to the watch strap in a fixed manner or in a manner inconvenient for quick detaching, causing inconvenience to replacement of the watch strap.SUMMARY

[0005] This application provides a wearable device, and a watch strap and a watch face that may be used in the wearable device. An objective is to provide a structure that can implement quick detaching of a watch strap.

[0006] To achieve the foregoing objective, the following technical solutions are used in embodiments of this application.

[0007] According to a first aspect, this application provides a watch strap. The watch strap may be used in a wearable device. For example, the wearable device may be a watch or a wristband.

[0008] The watch strap provided in this application may include a strap body and a watch strap quick-release structure disposed on the strap body. The watch strap quick-release structure is configured to connect to a watch face. The watch strap quick-release structure includes a movable member and a button. The movable member is able to move in a first direction, to enable the movable member to connect to the watch face. The button is able to move in a second direction intersecting the first direction. The movable member includes a first fitting portion, and the button includes a second fitting portion. The first fitting portion is farther away from a part, used for connecting to the watch face, of the movable member than the second fitting portion. When the button moves, the second fitting portion pushes the first fitting portion, and the movable member is able to move in a direction opposite to the first direction, to detach from the watch face.

[0009] For example, a snap-fit slot accessible to the movable member is provided on the watch face. When the watch strap needs to be connected to the watch face, the movable member may extend into the snap-fit slot, to implement snap-fit between the watch strap and the watch face. When the watch strap and the watch face that are connected together need to be detached, the button may be pressed, and the button transfers an acting force to the second fitting portion of the movable member that fits the first fitting portion. Under the acting force, the movable member may move in a direction away from the snap-fit slot, so that the movable member can be removed from the snap-fit slot, and the watch strap is detached from the watch face. The watch strap quick-release structure with a simple structure and ease of operation can implement quick attaching / detaching of the watch strap.

[0010] In a feasible implementation, an interface of contact between the first fitting portion and the second fitting portion is a first inclined surface. The movable member has a first side and a second side that are arranged back to back, and the first side is closer to the button than the second side. The movable member has a first end connected to the watch face and a second end opposite to the first end. In a direction in which the first end portion points to the second end portion, the first inclined surface is inclined in a direction from the second side to the first side.

[0011] In this example, an interface of fitting between the button and the movable member is designed as an inclined surface. When the button pushes the movable member, a pushing force produces, on the inclined surface, a component force facing away from the snap-fit slot. The component force may enable the movable member to move in a direction away from the snap-fit slot, so that the movable member can be removed from the snap-fit slot.

[0012] In a feasible implementation, a tilt angle of the inclined surface is less than or equal to 45°.

[0013] In this way, the movable member can be quickly removed from the snap-fit slot.

[0014] In a feasible implementation, the watch strap quick-release structure further includes a first limiting structure, and the first limiting structure is configured to limit a distance that the movable member moves in the first direction.

[0015] The limiting structure may limit a moving distance of the movable member, so that the movable member can accurately extend into the snap-fit slot or be accurately removed from the snap-fit slot.

[0016] In a feasible implementation, the first limiting structure includes a limiting slot, the limiting slot is provided on the movable member, and the second fitting portion of the button is located in the limiting slot. The limiting slot includes a first wall surface and a second wall surface that are arranged face to face, the second wall surface is farther away from the first end of the movable member than the first wall surface, and the second wall surface is the first inclined surface.

[0017] In this implementation, the limiting slot is provided on the movable member, the second fitting portion of the button extends into the limiting slot, and a moving distance of the movable member is limited through fitting between the second fitting portion and the movable member.

[0018] In addition, one wall surface of the limiting slot directly serves as a bonding interface between the movable member and the button, so that a structure of the device is more compact and meets a requirement for a miniaturization design of the device.

[0019] In a feasible implementation, the movable member is made of an elastic material. For example, the movable member may be made of a memory alloy material.

[0020] In a feasible implementation, the watch strap quick-release structure further includes an elastic member. The elastic member is connected to the movable member, and the elastic member is configured to provide an elastic force for the movable member to move in the first direction.

[0021] When the movable member is inserted into a snap-fit slot of a connecting piece, the elastic force applied by the elastic member to the movable member can help improve reliability of a connection between the watch strap and the watch face.

[0022] In a feasible implementation, the watch strap quick-release structure further includes a second limiting structure. The movable member is connected to the watch face, and the second limiting structure is configured to limit the strap body to move in 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.

[0023] In this example of this application, when the movable member extends into the snap-fit slot, movement of the watch strap in a thickness direction (for example, a Z direction) of the watch strap may be limited by the snap-fit slot, and movement of the watch strap in a length direction (for example, an X direction) of the watch strap and a width direction (for example, a Y direction) of the watch strap may be limited by the second limiting structure. In this way, the watch face and the watch strap are locked in a plurality of directions.

[0024] In a feasible implementation, the watch strap quick-release structure further includes a third limiting structure, and the third limiting structure is configured to limit a distance that the button moves in the second direction.

[0025] In a feasible implementation, the watch strap further includes a mounting housing. The mounting housing is detachably mounted to an end portion of the strap body. A part of the button and the movable member are disposed in the mounting housing. A surface, facing the watch face, of the mounting housing has a through hole, and a part of the movable member passes through the through hole. The mounting housing has a first side surface and a second side surface that are arranged back to back. The first side surface of the mounting housing is closer to skin than the second side surface. A part of the button extends into the mounting housing through the first side surface of the mounting housing.

[0026] A detachable structure is integrated into the mounting housing to form a module, and the module is detachably mounted to the strap body. This facilitates mounting / removal of the module or replacement of the module.

[0027] In a feasible implementation, a sliding slot is provided on one of the button and the mounting housing, and a sliding block slidably disposed in the sliding slot is provided on the other of the button and the mounting housing. An extension direction of the sliding slot is parallel to the second direction. A distance that the button moves in the second direction is limited through fitting between the sliding slot and the sliding block.

[0028] A moving distance of the button is limited through fitting between the sliding slot and the sliding block.

[0029] In a possible implementation, the mounting housing includes a body and a cover. The body and the cover are detachably connected. A part of the button and a part of the movable member are disposed in mounting space formed by the body and the cover. The body is provided with a mounting hole. A part of the button extends into the mounting space through the mounting hole.

[0030] In a feasible implementation, the watch strap quick-release structure further includes an anti-falling structure for preventing the button from sliding out of the first side surface. The anti-falling structure includes an extension portion disposed on the button, and the cover has a supporting boss for supporting the extension portion.

[0031] The button is disposed on a rear surface of the watch strap. Therefore, through fitting between the extension portion on the button and the supporting boss on the mounting housing, the button can be prevented from falling out of the mounting housing.

[0032] In a feasible implementation, an end face, used for connecting to the watch face, of the movable member is a second inclined surface.

[0033] In a feasible implementation, the movable member has the first side and the second side that are arranged back to back, and the first side is closer to the button than the second side. The movable member has the first end connected to the watch face and the second end opposite to the first end. In the direction in which the first end portion points to the second end portion, the second inclined surface is inclined in a direction from the first side to the second side.

[0034] In a feasible implementation, an end face, away from the movable member, of the button protrudes from an outer wall surface of the mounting housing.

[0035] In a feasible implementation, a moving direction of the movable member, that is, the first direction, is perpendicular to a moving direction of the button, that is, the second direction, and the first direction is perpendicular to a thickness direction of the watch face.

[0036] In a feasible implementation, a moving direction of the movable member, that is, the first direction, is perpendicular to a moving direction of the button, that is, the second direction, and the first direction is not perpendicular to a thickness direction of the watch face. To be specific, the first direction is inclined relative to the thickness direction of the watch face.

[0037] According to a second aspect, this application provides a wearable device. The wearable device includes a watch face and the watch strap according to any one of the foregoing implementations. The watch strap is connected to a movable member.

[0038] The wearable device includes the watch strap according to the foregoing implementations. Therefore, a detachable structure disposed on the watch strap can implement quick attaching / detaching between the watch strap and the watch face. In this way, a user can quickly replace the watch strap or the watch face according to a requirement.

[0039] In a feasible implementation, a snap-fit slot is provided on the watch face, and the movable member moving in a first direction is able to be inserted into the snap-fit slot, to enable the movable member to connect to the watch face.

[0040] In this application, a simple structure and ease of implementation are achieved through fitting between the snap-fit slot and the movable member.

[0041] In a feasible implementation, the watch strap further includes a mounting housing. The mounting housing is detachably mounted to an end portion of the strap body. An accommodating slot for inserting the mounting housing is provided on the watch face. A first opening is provided on a side, close to skin, of the accommodating slot. The mounting housing is able to be disposed in the accommodating slot through the first opening.

[0042] An opening is provided on a side, close to the skin, of the mounting housing. Therefore, during mounting of the watch strap, the watch strap may slide into the accommodating slot through the opening from bottom to top, so that the movable member is inserted into the snap-fit slot, and the watch strap is connected to the watch face.

[0043] In a feasible implementation, the watch strap quick-release structure further includes a second limiting structure. The movable member is connected to the watch face, and the second limiting structure is configured to limit the strap body to move in 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.

[0044] Movement of the watch strap relative to the watch face in a thickness direction (for example, a Z direction) of the watch strap may be limited through fitting between the snap-fit slot and the movable member. Movement of the watch strap in a length direction (for example, an X direction) of the watch strap and a width direction (for example, a Y direction) of the watch strap may be limited by the second limiting structure. In this way, the watch face and the watch face are locked in a plurality of directions.

[0045] In a feasible implementation, the accommodating slot has a first wall surface and a second wall surface that are arranged face to face, and the first wall surface and the second wall surface are arranged in a direction consistent with a width direction of the strap body. The second limiting structure includes a limiting slot and a limiting bump. One of the limiting slot and the limiting bump is provided on the mounting housing, and the other is disposed on the first wall surface and the second wall surface.

[0046] When the watch strap is inserted into the accommodating slot, through fitting between the limiting slot and the limiting bump, the watch strap may be prevented from moving in the width direction of the watch strap, and the watch strap may also be prevented from moving in the length direction of the watch strap, to implement position limiting in both directions.

[0047] In a feasible implementation, the accommodating slot has a second opening facing the strap body and a bottom opposite to the second opening. In a direction from the second opening of the accommodating slot to the bottom of the accommodating slot, a slot width of the accommodating slot gradually increases, and a width dimension of the mounting housing gradually increases, to form the second limiting structure.

[0048] The accommodating slot for inserting the watch strap is arranged to be of a structure with a variable slot width. To be specific, the accommodating slot is of a dovetail slot structure. This can not only prevent the watch strap from moving in the width direction of the watch strap, but also prevent the watch strap from moving in the length direction of the watch strap, to implement position limiting in both directions.

[0049] According to a third aspect, this application provides a watch strap quick-release structure. The watch strap quick-release structure is configured to connect a watch face to a watch strap. The watch strap quick-release structure may be disposed on the watch strap or the watch face.

[0050] The watch strap quick-release structure includes a mounting housing, a movable member, and a button. The movable member is able to move in a first direction, to enable the movable member to connect to the watch strap or the watch face. The button is able to move in a second direction intersecting the first direction. The movable member includes a first fitting portion, and the button includes a second fitting portion. The first fitting portion is farther away from a part, used for connecting to the watch strap or the watch face, of the movable member than the second fitting portion. When the button moves, the second fitting portion pushes the first fitting portion, and the movable member is able to move in a direction opposite to the first direction, to detach from the watch strap or the watch face.

[0051] In a feasible implementation, an interface of contact between the first fitting portion and the second fitting portion is a first inclined surface. The movable member has a first side and a second side that are arranged back to back, and the first side is closer to the button than the second side. The movable member has a first end connected to the watch face and a second end opposite to the first end. In a direction in which the first end portion points to the second end portion, the first inclined surface is inclined in a direction from the second side to the first side.

[0052] When the button pushes the movable member, a pushing force produces, on the inclined surface, a component force facing away from the snap-fit slot. The component force may enable the movable member to move in a direction away from the snap-fit slot, so that the movable member can be removed from the snap-fit slot.

[0053] In a feasible implementation, the watch strap quick-release structure further includes a first limiting structure, and the first limiting structure is configured to limit a distance that the movable member moves in the first direction.

[0054] The limiting structure may limit a moving distance of the movable member, so that the movable member can accurately extend into the snap-fit slot or be accurately removed from the snap-fit slot.

[0055] In a feasible implementation, the first limiting structure includes a limiting slot, the limiting slot is provided on the movable member, and the second fitting portion of the button is located in the limiting slot. The limiting slot includes a first wall surface and a second wall surface that are arranged face to face, the second wall surface is farther away from the first end of the movable member than the first wall surface, and the second wall surface is the first inclined surface.

[0056] In a feasible implementation, the watch strap quick-release structure further includes an elastic member. The elastic member is connected to the movable member, and the elastic member is configured to provide an elastic force for the movable member to move in the first direction.

[0057] In a feasible implementation, the watch strap quick-release structure further includes a second limiting structure. The movable member is connected to the watch face, and the second limiting structure is configured to limit the strap body to move in 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.

[0058] In this way, the watch face and the watch strap can be locked in a plurality of directions.

[0059] In a feasible implementation, the watch strap quick-release structure further includes a third limiting structure, and the third limiting structure is configured to limit a distance that the button moves in the second direction.

[0060] In a feasible implementation, a sliding slot is provided on one of the button and the mounting housing, and a sliding block slidably disposed in the sliding slot is provided on the other of the button and the mounting housing. An extension direction of the sliding slot is parallel to the second direction. A distance that the button moves in the second direction is limited through fitting between the sliding slot and the sliding block.

[0061] In a possible implementation, the mounting housing includes a body and a cover. The body and the cover are detachably connected. A part of the button and a part of the movable member are disposed in mounting space formed by the body and the cover. The body is provided with a mounting hole.

[0062] In a feasible implementation, the watch strap quick-release structure further includes an anti-falling structure for preventing the button from sliding out of the first side surface. The anti-falling structure includes an extension portion disposed on the button, and the cover has a supporting boss for supporting the extension portion.

[0063] According to a fourth aspect, this application provides a watch face. The watch face may be used in a wearable device. For example, the wearable device may be a watch or a wristband.

[0064] The watch face provided in this application may include a watch body and a watch strap quick-release structure disposed on the watch body. The watch strap quick-release structure is configured to connect to a watch strap. The watch strap quick-release structure includes a movable member and a button. The movable member is able to move in a first direction, to enable the movable member to connect to the watch strap. The button is able to move in a second direction intersecting the first direction. The movable member includes a first fitting portion, and the button includes a second fitting portion. The first fitting portion is farther away from a part, used for connecting to the watch strap, of the movable member than the second fitting portion. When the button moves, the second fitting portion pushes the first fitting portion, and the movable member is able to move in a direction opposite to the first direction, to detach from the watch strap.

[0065] In this example of this application, the watch strap quick-release structure is disposed on the watch face. For example, a snap-fit slot accessible to the movable member may be provided on the watch strap. If the watch strap needs to be connected to the watch face, the movable member may be inserted into the snap-fit slot. If the watch strap and the watch face that are connected together need to be detached, the button may be pressed, and the button transfers an acting force to the second fitting portion of the movable member that fits the first fitting portion. Under the acting force, the movable member may move in a direction away from the snap-fit slot, so that the movable member can be removed from the snap-fit slot, and the watch strap is detached from the watch face.

[0066] In a feasible implementation, an interface of contact between the first fitting portion and the second fitting portion is a first inclined surface. The movable member has a first side and a second side that are arranged back to back, and the first side is closer to the button than the second side. The movable member has a first end connected to the watch face and a second end opposite to the first end. In a direction in which the first end portion points to the second end portion, the first inclined surface is inclined in a direction from the second side to the first side.

[0067] In this example, an interface of fitting between the button and the movable member is designed as an inclined surface. When the button pushes the movable member, a pushing force produces, on the inclined surface, a component force facing away from the snap-fit slot. The component force may enable the movable member to move in a direction away from the snap-fit slot, so that the movable member can be removed from the snap-fit slot.

[0068] In a feasible implementation, a tilt angle of the inclined surface is less than or equal to 45°.

[0069] In this way, the movable member can be quickly removed from the snap-fit slot.

[0070] In a feasible implementation, the watch strap quick-release structure further includes a first limiting structure, and the first limiting structure is configured to limit a distance that the movable member moves in the first direction.

[0071] The limiting structure may limit a moving distance of the movable member, so that the movable member can accurately extend into the snap-fit slot or be accurately removed from the snap-fit slot.

[0072] In a feasible implementation, the first limiting structure includes a limiting slot, the limiting slot is provided on the movable member, and the second fitting portion of the button is located in the limiting slot. The limiting slot includes a first wall surface and a second wall surface that are arranged face to face, the second wall surface is farther away from the first end of the movable member than the first wall surface, and the second wall surface is the first inclined surface.

[0073] In this implementation, the limiting slot is provided on the movable member, the second fitting portion of the button extends into the limiting slot, and a moving distance of the movable member is limited through fitting between the second fitting portion and the movable member.

[0074] In addition, one wall surface of the limiting slot directly serves as a bonding interface between the movable member and the button, so that a structure of the device is more compact and meets a requirement for a miniaturization design of the device.

[0075] In a feasible implementation, the watch strap quick-release structure further includes an elastic member. The elastic member is connected to the movable member, and the elastic member is configured to provide an elastic force for the movable member to move in the first direction.

[0076] When the movable member is inserted into a snap-fit slot of a connecting piece, the elastic force applied by the elastic member to the movable member can help improve reliability of a connection between the watch strap and the watch face.

[0077] In a feasible implementation, the watch strap quick-release structure further includes a second limiting structure. The movable member is connected to the watch strap, and the second limiting structure is configured to limit the watch body to move in 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.

[0078] In this example of this application, when the movable member extends into the snap-fit slot, movement of the watch strap in a thickness direction (for example, a Z direction) of the watch strap may be limited by the snap-fit slot, and movement of the watch strap in a length direction (for example, an X direction) of the watch strap and a width direction (for example, a Y direction) of the watch strap may be limited by the second limiting structure.

[0086] In a feasible implementation, an end face, away from the movable member, of the button is flush with the rear surface of the watch body.

[0087] In this example of this application, a detachable structure is disposed in the watch face. Therefore, when performing an operation, a user may hold the watch strap with one hand and press the button with the other hand, to align the end face, away from the movable member, of the button with the rear surface of the watch body, to facilitate the operation. In addition, because the button is disposed on the rear surface of the watch face, wearing comfort can be further improved.

DESCRIPTION OF EMBODIMENTS

[0104] Embodiments of this application provide a wearable device. For example, the wearable device may be a smart band or a smartwatch. The wearable device may be worn on a wrist to implement functions such as time display, time recording, time reporting, message notification, motion detection, heart rate monitoring, and blood oxygen level detection.

[0105] The wearable device may include a strap body and a watch body. The strap body is configured to wrap around a wrist of a user, to implement wearing of the wearable device. The watch body is used for display.

[0106] FIG. 1 is a diagram of an example structure of a wearable device. For example, 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 may be connected through 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 wrap around a wrist.

[0107] To meet a requirement of a user for a changeable style, the watch face and the watch strap may be detachably connected. For example, the watch face and the watch strap are connected through a watch strap quick-release structure. In this way, the user can quickly detach the watch strap, and replace the watch strap or the watch face with a needed watch strap or watch face.

[0108] FIG. 2 is a diagram of a partial structure of a wearable device according to an embodiment of this application. FIG. 3 is an exploded view of FIG. 2, and includes a watch strap quick-release structure 40. The watch strap quick-release structure 40 is disposed at a joint between a strap body 20 of a watch strap and a watch body 10 of a watch face.

[0109] In this example of this application, a material of the strap body 20 includes but is not limited to metal, plastic, and the like. Space is formed in the watch body 10, and an electronic component or another mechanical part is disposed in the space.

[0110] As shown in FIG. 3, the watch strap quick-release structure 40 includes a snap-fit slot 401, a movable member 402, and a button 403. The movable member 402 and the button 403 form a locking member through fitting. One of the snap-fit slot 401 and the locking member is provided on the strap body 20, and the other is provided on the watch body 10. For example, in the example of FIG. 3, the snap-fit slot 401 is provided on the strap body 20, and the locking member including the movable member 402 and the button 403 is disposed on the watch body 10.

[0111] FIG. 4 briefly shows a structure and an attaching / detaching principle of the watch strap quick-release structure 40 in this example of this application.

[0112] As shown in FIG. 4, the movable member 402 can move in a first direction (a P1 direction shown in FIG. 4). For example, the first direction may be an extension direction of the strap body, so that the movable member 402 can enter and exit the snap-fit slot 401. As shown in (a) and (b) in FIG. 4, when the strap body and the watch body need to be connected, a mechanical part provided with the snap-fit slot 401 and the movable member 402 may approach each other, and an end portion of the movable member 402 may be inserted into the snap-fit slot 401, to implement snap-fit between the strap body and the watch body.

[0113] As shown in FIG. 4, the button 403 can move in a second direction intersecting the first direction P1. For example, as shown in (a) in FIG. 4, the button 403 may move in an L1 direction that is perpendicular to the extension direction P1 of the strap body. The L1 direction may be parallel to a thickness direction of the strap body. As shown in (c) and (d) in FIG. 4, the button 403 moving toward the movable member 402 moves in the L1 direction shown in (c) in FIG. 4. This may drive the movable member 402 to move in a direction away from the snap-fit slot 401. As shown in (c) in FIG. 4, the movable member 402 moves in a P2 direction opposite to the P1 direction. In this way, the movable member 402 can be removed from the snap-fit slot 401, to detach the strap body from the watch body, as shown in (d) in FIG. 4.

[0114] To enable the button 403 that moves to drive the movable member 402 to move in the direction away from the snap-fit slot 401, in some implementations, as shown in FIG. 4, the movable member 402 includes a first fitting portion 4021 that fits the button 403, and the button 403 includes a second fitting portion 4031 that fits the movable member 402. The first fitting portion 4021 of the movable member 402 is farther away from the snap-fit slot 401 than the second fitting portion 4031 of the button 403. To be specific, compared with the second fitting portion 4031, the first fitting portion 4021 is farther away from a part, used for extending into the snap-fit slot 401, of the movable member 402.

[0115] In this way, when the button 403 is pressed, the button 403 may transfer an acting force to the first fitting portion 4021 through the second fitting portion 4031. Under the acting force, the movable member 402 including the first fitting portion 4021 can move in the direction away from the snap-fit slot 401, so that the movable member 402 can be removed from the snap-fit slot 401.

[0116] As shown in FIG. 4 and FIG. 5, an interface of contact between the first fitting portion 4021 and the second fitting portion 4031 may be an inclined surface, for example, an inclined plane.

[0117] That the interface of contact between the first fitting portion 4021 and the second fitting portion 4031 is an inclined plane may be understood as follows: As shown in FIG. 6, the movable member 402 has a first side and a second side that are arranged back to back, and the first side is closer to the button 403 than the second side. The movable member 402 has a first end for accessing the snap-fit slot 401 and a second end opposite to the first end. In a direction in which the first end points to the second end, the inclined plane is inclined in a direction from the second side to the first side. When the movable member 402 needs to be removed from the snap-fit slot 401, as shown in FIG. 6, a pushing force F may be applied to the button 403, to produce a pushing force f at the interface between the first fitting portion 4021 of the movable member 402 and the second fitting portion 4031 of the button 403. The pushing force f produces a force f1 for pushing the movable member 402 to move in the P2 direction, so that the movable member 402 moves in the P2 direction and is removed from the snap-fit slot 401.

[0118] In some examples, as shown in FIG. 6, a tilt angle α of the inclined plane may be less than or equal to 45°. For example, the tilt angle α may be equal to 45°, 40°, or 30°. In this way, when the button 403 is pushed, the movable member 402 can be quickly removed from the snap-fit slot 401 in response.

[0119] In some examples, as shown in FIG. 6, a limiting slot 4022 may be provided on the movable member 402. The second fitting portion 4031 of the button 403 is located in the limiting slot 4022. A part, located in the limiting slot 4022 and away from the button 403, of the movable member 402 is the first fitting portion 4021. This can save space, so that a structure of the device is more compact. For example, when the button 403 moves in the thickness direction of the strap body, an example shown in FIG. 7 is used, without occupying a dimension in the thickness direction of the strap body or a thickness direction of the watch body.

[0120] In some other examples, as shown in FIG. 5, a bump may be formed on a side, close to the button 403, of the movable member 402, and the bump forms the first fitting portion 4021.

[0121] In another example, structures of the first fitting portion 4021 and the second fitting portion 4031 may alternatively be in other forms.

[0122] After the strap body is detached from the watch body through the watch strap quick-release structure, the movable member 402 further needs to return to an initial position, as shown in (c) and (d) in FIG. 4. To be specific, the movable member 402 needs to move toward the snap-fit slot in the P1 direction, to fit the snap-fit slot again.

[0123] In some embodiments, the movable member 402 may be made of an elastic material, for example, a memory alloy material.

[0124] In some other embodiments, as shown in FIG. 6, an elastic member 404 may be used. The elastic member 404 is connected to the movable member 402, and the elastic member 404 is configured to provide an elastic force for the movable member 402 to move toward the snap-fit slot 401. Therefore, after the movable member 402 is removed from the snap-fit slot 401 and the pushing force F applied to the button 403 is released, the movable member 402 may move leftward under the action of the elastic force of the elastic member 404, to return to the initial position.

[0125] The watch strap quick-release structure in this example of this application may further include a limiting structure. The limiting structure is configured to limit a distance that the movable member 402 moves in the first direction (for example, the extension direction of the strap body). A moving distance of the movable member 402 may be accurately controlled by the limiting structure, so that the movable member 402 accurately enters and exits the snap-fit slot 401, to improve reliability and stability of quick detaching between the strap body and the watch body.

[0126] FIG. 7 is a three-dimensional diagram of a partial structure of a wearable arrangement according to an example of this application. FIG. 8 is a diagram of a structure obtained through cutting along A-A shown in FIG. 7. As shown in FIG. 8, the limiting structure for limiting the moving distance of the movable member 402 may include a limiting slot 4022 provided on the movable member 402, and the second fitting portion 4031 of the button 403 is located in the limiting slot 4022.

[0127] FIG. 9 is an exploded view of removing the button 403 from the limiting slot 4022. The limiting slot 4022 includes a first wall surface and a second wall surface that are arranged face to face. The second wall surface is farther away from the snap-fit slot 401 than the first wall surface. The second wall surface is an inclined plane.

[0128] In the limiting structure shown in FIG. 9, the moving distance of the movable member 402 is limited through fitting between the button 403 and the limiting slot 4022.

[0129] In addition, a wall surface (for example, the second wall surface) of the limiting slot 4022 serves as an interface for attaching the movable member 402 to the button 403. In this way, a structure of the entire device is more compact, and a requirement for a miniaturization design of the device is met.

[0130] As shown in FIG. 9, in this embodiment, the movable member 402, the button 403, and the elastic member 404 are disposed on the watch body 10, and the snap-fit slot 401 is provided at an end portion of the strap body 20. A moving direction of the button 403 is perpendicular to the thickness direction of the watch body, and a moving direction of the movable member 402 is perpendicular to the thickness direction of the watch body. For example, the moving direction may be parallel to the extension direction of the strap body.

[0131] In some structures, as shown in FIG. 10, a connecting piece 50 may be disposed at the end portion of the strap body 20, and the snap-fit slot 401 is provided on the connecting piece 50.

[0132] In some alternative materials, the strap body 20 may be made of leather, metal, or the like, and the connecting piece 50 may be made of metal. The connecting piece 50 is fastened to the strap body 20.

[0133] FIG. 11 is a diagram of a structure of a watch body according to an embodiment of this application. FIG. 12 is a diagram of a partial structure of a cross-sectional view along B-B in FIG. 11. As shown in FIG. 11 and FIG. 12, an accommodating slot 103 for inserting the end portion of the strap body 20 shown in FIG. 10 is provided on the watch body 10, and a mounting cavity 101 is formed in the watch body 10. A part of the button 43, a part of the movable member 402, and the elastic member 404 are disposed in the mounting cavity 401. A through hole 102 is provided on the watch body 10, and the through hole 102 is in communication with the mounting cavity 101 and the accommodating slot 103. A part of the movable member 402 extends into the accommodating slot 103 through the through hole 102, and may fit the snap-fit slot 401.

[0134] In the example of FIG. 11 and FIG. 12, the watch body 10 serves as a carrier of the movable member 402, the button 403, and the elastic member 404, and a part of the movable member 402, the elastic member 404, and a part of the button 403 are hidden in the watch body 10, to improve appearance fineness of the entire device.

[0135] 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, space for disposing the elastic member 404 may be formed between the movable member 402 and the watch body 10. The elastic member 404 is disposed in the space. One end of the elastic member 404 abuts against the movable member 402, and the other end abuts against the watch body 10.

[0136] Still as shown in FIG. 12, a cavity 104 for allowing the button 403 to move is further provided in the watch body 10. For example, when the button 403 is pressed, the button 403 may extend into the cavity 104. The cavity 104 fully utilizes space in the watch body 10, to allow the button 403 to move without increasing a thickness dimension of the watch body.

[0137] In this example of this application, a limiting structure for limiting a moving distance of the button 403 may be further included. For example, as shown in FIG. 12, when the button 403 moves in the L1 direction (for example, the thickness direction of the watch body), the moving distance of the button 403 needs to be limited, to accurately push the movable member 402 to move.

[0138] The limiting structure for limiting the moving distance of the button 403 may be implemented in a plurality of manners.

[0139] For example, as shown in FIG. 12, a sliding slot 4032 is provided on the button 403, and a sliding block 105 slidably disposed in the sliding slot 4032 is provided on the watch body 10. An extension direction of the sliding slot 4032 is parallel to the thickness direction of the watch body. The moving distance of the button is limited through fitting between the sliding block 105 and the sliding slot 4032.

[0140] For another example, a sliding slot 4032 may be provided on the watch body 10, and a sliding block 105 is disposed on the button 403.

[0141] In some examples, as shown in FIG. 12, the watch body 10 includes a display surface and a rear surface arranged back to back with the display surface, and a part of the button 403 extends into the watch body through the rear surface.

[0142] In some structures, the movable member 402 extends into the snap-fit slot 401. As shown in FIG. 12, an end face, away from the movable member 402, of the button 403 is flush with the rear surface.

[0143] In this example of this application, the snap-fit slot 401 is provided on the strap body 20, and the button 403 is disposed on the watch body 10. Therefore, when a user needs to detach the strap body 20, the user may pinch the strap body 20 with the left hand, and may press the button 403 with the thumb of the right hand, instead of performing two actions with a same hand. Therefore, as shown in FIG. 12, the end face, away from the movable member 402, of the button 403 may be flush with the rear surface of the watch body 20. The two hands control different structures, so that operation difficulty is low. Therefore, the user can easily control the button 403, without a need to protrudingly dispose the button 403.

[0144] The button 403 is disposed on the rear surface of the watch body 10, and the rear surface of the watch body 10 needs to be in contact with skin. Therefore, the end face, away from the movable member 402, of the button 403 being flush with the rear surface can also improve wearing comfort and appearance fineness.

[0145] In addition, because the button 403 is disposed on the rear surface of the watch body, an anti-falling structure may be further disposed in the wearable device, to prevent the button 403 from falling off. FIG. 13 and FIG. 14 show an example anti-falling structure. FIG. 13 is a three-dimensional view of the button 403. FIG. 14 shows a connection relationship between the button 403 and the watch body 10. The button 403 has an extension portion 4033, and a supporting boss 106 for supporting the extension portion 4033 is disposed on the watch body 10. The extension portion 4033 is supported on the supporting boss 106, to prevent the button 403 from falling down (in the L2 direction in FIG. 14).

[0146] In the wearable device in this example of this application, after the movable member 402 extends into the snap-fit slot 401 to connect the strap body 20 to the watch body 10, the snap-fit slot 401 may limit the strap body 20 to move in the second direction (for example, the thickness direction of the strap body). However, the strap body 20 may move in another direction, for example, a third direction or fourth direction, and the strap body 20 and the watch body 10 cannot be locked. For example, the strap body 20 may move in the extension direction of the strap body, and may further move in a width direction of the strap body.

[0147] FIG. 15 is an exploded view of the watch body 10 and the strap body 20. FIG. 16 is a detailed diagram of a joint between the strap body and the watch body. As shown in FIG. 15, the accommodating slot 103 for inserting the end portion of the strap body 20 is provided on the watch body 10. As shown in FIG. 15 and FIG. 16, the accommodating slot 103 has a second opening facing the strap body 20 and a bottom opposite to the second opening. As shown in FIG. 16, in a direction from the second opening of the accommodating slot 103 to the bottom of the accommodating slot, a slot width (a dimension d shown in FIG. 16) of the accommodating slot 103 gradually increases. An accommodating slot structure formed in this manner may be referred to as a dovetail slot structure. As shown in FIG. 17, after the strap body 20 is inserted into the accommodating slot 103, the strap body 20 may be prevented from moving in an S direction (for example, the width direction of the strap body) shown in FIG. 17. In addition, because the slot width of the accommodating slot 103 gradually decreases in the direction from the second opening to the bottom, the strap body located in the accommodating slot cannot move in a T direction (for example, the extension direction of the strap body) shown in FIG. 17. Based on this structure, the strap body and the watch body may be locked in a plurality of directions, to improve connection reliability.

[0148] FIG. 18 is a diagram of a structure of a watch body. FIG. 19 is an exploded view of a watch body and a strap body. To connect the watch body 10 to the strap body 20, the accommodating slot 103 provided on the watch body 10 further has a first opening, and the first opening is located on a same side as the rear surface of the watch body. During mounting of the strap body 20, the strap body 20 may slide into the accommodating slot 103 through the first opening in an M direction shown in FIG. 19, and the movable member is inserted into the snap-fit slot, to implement snap-fit between the strap body and the watch body.

[0149] To improve user experience, as shown in FIG. 19, an end face, to be inserted into the snap-fit slot 401, of the movable member 402 is an inclined surface.

[0150] That the end face, to be inserted into the snap-fit slot 401, of the movable member 402 is an inclined surface may be understood as follows: The movable member 402 has the first side and the second side that are arranged back to back, and the first side is closer to the button 403 than the second side. The movable member 402 has the first end for accessing the snap-fit slot 401 and the second end opposite to the first end. In the direction in which the first end portion points to the second end portion, the inclined surface is inclined in the direction from the second side to the first side.

[0151] In this way, when the user pinches the strap body 20 to move it from bottom to top (for example, in the M direction in FIG. 19), the movable member 402 may be smoothly inserted into the snap-fit slot 401 along the inclined surface.

[0152] In addition, after the movable member 402 is inserted into the snap-fit slot 401, because the movable member 402 has the inclined surface, the inclined surface structure may further function for limiting, to prevent the strap body 20 from moving in a direction opposite to the M direction in FIG. 19, and prevent the movable member 402 from sliding out of the snap-fit slot 401.

[0153] In the foregoing example, the snap-fit slot 401 of the watch strap quick-release structure is provided on the watch strap, and the movable member 402 and the button 403 are disposed on the watch face. The following provides some other examples. In the examples, the snap-fit slot 401 is provided on the watch face, and the movable member 402 and the button 403 are disposed on the watch strap. For a specific implementation structure, refer to the following descriptions.

[0154] FIG. 20 is a diagram of a partial structure of a wearable device. In this example, a movable member and a button are integrated into a module 60, and the module 60 is disposed on a strap body 20. A snap-fit slot for fitting the movable member in the module 60 is provided on a watch body 10.

[0155] FIG. 21 is a schematic exploded view of the module 60 in FIG. 20. The module 60 includes a mounting housing. The mounting housing may include a body 601 and a cover 602. The body 601 and the cover 602 are snap-fitted to form internal mounting space 605.

[0156] In some examples, the body 601 and the cover 602 may be fastened through a fastener 604, or the body 601 and the cover 602 may be fastened through a welding process.

[0157] The body 601 and the cover 602 that are fastened may be fastened to the strap body 20 through a fastener 603 shown in FIG. 21. This facilitates mounting and removal of the module 60, or a component structure in the module may be replaced.

[0158] At least a part of the movable member 402, an elastic member 404, and the button 403 may be disposed in the mounting space 605.

[0159] FIG. 22 is a diagram of a structure of the module 60 in this example of this application. FIG. 23 is a diagram of a structure obtained through cutting along C-C in FIG. 22. As shown in FIG. 23, the body 601 and the cover 602 are snap-fitted, and the internal mounting space 605 is formed. A through hole 606 in communication with the mounting space 605 is provided on the body 601. The elastic member 404 is disposed in the mounting space 605. A part of the movable member 402 extends out of the module through the through hole 606, to fit the snap-fit slot. A part of the button 403 extends into the mounting space 605 and fits the movable member 402.

[0160] In this embodiment, refer to FIG. 4 in the foregoing example. The movable member 402 includes a first fitting portion 4021 that fits the button 403, and the button 403 includes a second fitting portion 4031 that fits the movable member 402. The first fitting portion 4021 of the movable member 402 is farther away from the snap-fit slot 4011 than the second fitting portion 4031 of the button 403. To be specific, compared with the second fitting portion 4031, the first fitting portion 4021 is farther away from a part, used for extending into the snap-fit slot 401, of the movable member 402.

[0161] When the button 403 is pressed, the button 403 may transfer an acting force to the first fitting portion 4021 through the second fitting portion 4031. Under the acting force, the movable member 402 including the first fitting portion 4021 can move in a direction away from the snap-fit slot 401, so that the movable member 402 can be removed from the snap-fit slot 401.

[0162] An interface of contact between the movable member 402 and the button 403 is an inclined plane. The button 403 that moves pushes the movable member 402, so that the movable member 402 moves in the direction away from the snap-fit slot, to be removed from the snap-fit slot, and the strap body can be detached from the watch body.

[0163] A tilt angle α of the inclined plane may be less than or equal to 45°. For example, the tilt angle α may be equal to 45°, 40°, or 30°. In this way, when the button 403 is pushed, the movable member 402 can be quickly removed from the snap-fit slot 401 in response.

[0164] FIG. 24 is a diagram of two different connection relationships between the movable member 402 and the button 403 in this example of this application. In two different examples, a limiting slot 4022 is provided on the movable member 402, and a part of the button 403 extends into the limiting slot 4022. The limiting slot 4022 may limit a moving distance of the movable member 402. A principle of limiting has been explained in the foregoing examples, and details are not described herein again.

[0165] The button 403 has a moving stroke. For example, in this example, the button 403 is disposed on the strap body, and needs to have a moving stroke in a thickness direction of the strap body. Therefore, moving space needs to be reserved for the button 403 in a mechanical part.

[0166] For example, in an example shown in (b) in FIG. 24, the movable member 402 and the button 403 are disposed on the watch body 10, and space in the watch body 10 may be fully utilized. To be specific, a cavity 104 may be provided on the watch body 20, and the button 403 that moves may extend into the cavity 104. In an example shown in (a) in FIG. 24, both the movable member 402 and the button 403 are disposed on the strap body. The strap body is thin and has a compact structure. If a structure similar to that shown in the example in (b) in FIG. 24 is used, a thickness dimension of the strap body may increase. In this example of this application, as shown in (a) in FIG. 24, an extension portion 4023 may be disposed on a side, close to the button 403, of the movable member 402, and the extension portion 4023 is attached to a part of the button 403, to ensure the moving stroke of the button 403.

[0167] Return to FIG. 23. In this example of this application, a limiting structure for limiting a moving distance of the button 403 may be further included. For example, a sliding slot 4032 is provided on the button 403, and a sliding block 6021 slidably disposed in the sliding slot 4032 is provided on the cover 602. An extension direction of the sliding slot 4032 may be parallel to the thickness direction of the strap body. The moving distance of the button is limited through fitting between the sliding block 6021 and the sliding slot 4032.

[0168] For another example, a sliding slot may be provided on the cover, and a sliding block is disposed on the button.

[0169] In some examples, the button 403 is disposed on a rear surface of the strap body, to be specific, is disposed on a surface close to skin. In this case, when a user needs to detach the strap body 20, the user needs to both pinch the strap body and press the button 403 with the left hand. To facilitate a user operation, as shown in FIG. 25, an end face, away from the movable member 402, of the button 403 may protrude from a surface of the mounting housing 60A.

[0170] In addition, because the button 403 is disposed on the rear surface of the strap body, an anti-falling structure may be further disposed in the wearable device, to prevent the button 403 from falling off. For example, a supporting boss may be disposed on the mounting housing 60A, and a part of the button 403 is disposed on the supporting boss. Alternatively, FIG. 26 shows an example anti-falling structure. The cover 602 of the mounting housing has a supporting boss, and the supporting boss may be the sliding block 6021 in the limiting structure. A part of the button 403, for example, the extension portion 4033, is disposed on the sliding block 6021, to prevent the button 403 from falling down.

[0171] From the perspective of an assembly process, the button 403 may extend into the body 601 through a hole on the body 601, and then the cover 602 is mounted. In addition, the sliding block 6021 of the cover 602 shown in FIG. 26 is enabled to extend into the sliding slot 4032 of the button 403, and then the cover 602 is fastened to the body 601 through a fastener.

[0172] After the movable member 402 extends into the snap-fit slot 401 to connect the strap body 20 to the watch body 10, the snap-fit slot 401 may limit the strap body 20 to move in the thickness direction of the strap body. However, the strap body 20 may move in an extension direction of the strap body, and may further move in a width direction of the strap body.

[0173] FIG. 27 is a diagram of a structure of a watch body 10. FIG. 28 is a diagram of a structure of a module disposed on a strap body. As shown in FIG. 26, an accommodating slot 103 for inserting an end portion of the strap body 20 is provided on the watch body 10. The accommodating slot 103 has a first wall surface and a second wall surface that are arranged face to face. The first wall surface and the second wall surface are arranged in a direction consistent with a width direction of the strap body.

[0174] As shown in FIG. 27, a limiting slot 101 may be provided on both the first wall surface and the second wall surface. As shown in FIG. 28, a limiting bump 607 that may be inserted into the limiting slot 101 is disposed on an outer wall surface of the module.

[0175] In some other examples, a limiting slot may alternatively be provided on the outer wall surface of the module, and limiting bumps may be disposed on the first wall surface and the second wall surface.

[0176] In this example of this application, after the strap body snap-fits into the watch body, through fitting between the limiting bump 607 and the limiting slot 101, the strap body may be prevented from moving relative to the watch body in a width direction (for example, an S direction in FIG. 28) of the strap body, and the strap body may be prevented from moving relative to the watch body in an extension direction (for example, a T direction in FIG. 28) of the strap body. In this way, the strap body and the watch body are locked in a plurality of directions.

[0177] Return to FIG. 27. To connect the watch body 10 to the strap body 20, the accommodating slot 103 provided on the watch body 10 further has a second opening, and the first opening is located on a same side as a rear surface of the watch body. During mounting of the strap body 20, the strap body 20 may slide into the accommodating slot 103 through the first opening in an M direction shown in FIG. 27, and the movable member is inserted into the snap-fit slot, to implement snap-fit between the strap body and the watch body.

[0178] To improve user experience, as shown in FIG. 29, an end face, to be inserted into the snap-fit slot 401, of the movable member 402 is an inclined surface.

[0179] That the end face, to be inserted into the snap-fit slot 401, of the movable member 402 is an inclined surface may be understood as follows: The movable member 402 has a first side and a second side that are arranged back to back, and the first side is closer to the button 403 than the second side. The movable member 402 has a first end for accessing the snap-fit slot 401 and a second end opposite to the first end. In a direction in which the first end portion points to the second end portion, the inclined surface is inclined in a direction from the second side to the first side.

[0180] In this way, when the user pinches the strap body 20 to move it from bottom to top (for example, in the M direction in FIG. 29), the movable member 402 may be smoothly inserted into the snap-fit slot 401 along the inclined surface.

[0181] In addition, after the movable member 402 is inserted into the snap-fit slot 401, because the movable member 402 has the inclined surface, the inclined surface structure may further function for limiting, to prevent the strap body 20 from moving in a direction opposite to the M direction in FIG. 29, and prevent the movable member 402 from sliding out of the snap-fit slot 401.

[0182] When a locking member including the movable member 402 and the button 403 is disposed on the watch strap, the movable member 402 and the button 403 have a plurality of moving directions. The following provides two manners as examples.

[0183] FIG. 30 is a cross-sectional view of an example partial structure of a wearable device. In this embodiment, a movable member 402 may move in a P direction, a button 403 may move in an L direction, and a thickness direction of a watch face is H. A moving direction of the movable member 402, that is, the P direction, is perpendicular to a moving direction of the button 403, that is the L direction. The moving direction of the movable member 402, that is, the P direction, is not perpendicular to the thickness direction H of the watch face. For example, an included angle greater than 90 degrees exists between the P direction and the H direction.

[0184] FIG. 31 is a cross-sectional view of an example partial structure of another wearable device. In this embodiment, a movable member 402 may move in a P direction, a button 403 may move in an L direction, and a thickness direction of a watch face is H. A moving direction of the movable member 402, that is, the P direction, is perpendicular to a moving direction of the button 403, that is the L direction. The moving direction of the movable member 402, that is, the P direction, is perpendicular to the thickness direction H of the watch face.

[0185] In the descriptions of this specification, specific features, structures, materials, or characteristics may be combined in a proper manner in any one or more of embodiments or examples.

[0186] The foregoing descriptions are merely specific implementations of this application, but are not intended to limit the protection scope of this application. Any variation or replacement readily figured out by a person skilled in the art within the technical scope disclosed in this application shall fall within the protection scope of this application. Therefore, the protection scope of this application shall be subject to the protection scope of the claims.
