Description

Technical Field

[0001] This application relates to the field of wearable device technology, and more particularly to a quick-release mechanism, a watch strap, and a wearable device. Background Technology

[0002] In some wearable devices (such as watches), the watch body and the watch band can be connected via a quick-release mechanism, allowing users to easily connect and disconnect the band. Some watch bands consist of multiple linked links connected sequentially; changing the number of links adjusts the band length, and two links can be connected and disconnected via a quick-release mechanism on the link itself.

[0003] How to provide a quick-release mechanism, watch strap, and wearable device with fewer parts and a simpler structure is a challenge that the industry needs to address. Utility Model Content

[0004] This application provides a quick-release mechanism, a watch strap, and a wearable device. The quick-release mechanism has fewer parts and a simple structure.

[0005] The embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, embodiments of this application provide a quick-release mechanism, including a base, a spring bar, an elastic element, and a button. The base has a first groove, an opening, and a second groove. The opening and the first groove communicate along a first direction, and the first and second grooves communicate along a second direction. The spring bar includes a sliding portion and a rod portion. The sliding portion is connected to one end of the rod portion, and the other end of the rod portion is a mounting end that passes through the opening. The sliding portion is slidably mounted in the first groove along the first direction. The elastic element is disposed within the first groove and acts on the sliding portion. The button is slidably mounted in the second groove along the second direction to switch between a first position and a second position. The button has a mating portion that slidably engages with the sliding portion. During the movement of the button from the first position to the second position, the mating portion abuts against the sliding portion to cause the sliding portion to move along the first direction, and the mounting end gradually retracts into the opening. During the movement of the button from the second position to the first position, the elastic element acts on the sliding portion to cause the sliding portion to move along the first direction, the mounting end gradually extends out of the opening, and the sliding portion abuts against the mating portion to cause the button to move from the second position to the first position.

[0007] The quick-release mechanism provided in this embodiment has a spring bar mounted on a base. The sliding portion of the spring bar is slidably mounted in a first groove of the base, and the rod portion of the spring bar passes through an opening in the base. An elastic element is disposed within the first groove and acts on the sliding portion. A button is slidably mounted in a second groove of the base to switch between a first position and a second position. During the movement of the button from the first position to the second position, the mating portion of the button pushes the sliding portion of the spring bar, causing the sliding portion to move. The mounting end gradually retracts into the opening, and the elastic element gradually shortens to store energy. During the movement of the button from the second position to the first position, the elastic element extends to release energy, pushes the sliding portion of the spring bar, causing the sliding portion to move. The mounting end gradually extends out of the opening, and the sliding portion abuts against the mating portion, causing the button to move from the second position to the first position. This quick-release mechanism has fewer components and a simpler structure.

[0008] In one alternative implementation, during the pressing process, the button moves from a first position to a second position. When the button is pressed and released, it moves from the second position back to the first position. The first position can be a released position, and the second position can be a pressed position.

[0009] In one alternative implementation, the base extends along a first direction, and the dimension of the base along the first direction is larger than the dimension of the base along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. The base can be configured as a strip or a flat block extending approximately along the first direction. The quick-release mechanism has a compact overall structure and occupies less space.

[0010] In one alternative implementation, the base dimension along a third direction is less than or equal to 3 mm. The spring bar, elastic element, and button are arranged within the small-sized base, resulting in a compact overall structure for the quick-release mechanism.

[0011] In one alternative implementation, the sliding part has a slot. When the button is in the second position, the mating part is located in the slot. This allows the spring bar to be smaller in size along the second and third directions, resulting in a compact overall structure.

[0012] In one alternative implementation, the sliding part can be roughly frame-shaped, with slots formed inside the frame structure.

[0013] In one alternative implementation, the button and the elastic element are stacked along the second direction, and the elastic element is compressed along the first direction. By making full use of the internal space of the base, the elastic element and the button are arranged in a small base, allowing the size of the base along the third direction to be small, resulting in a compact overall structure for the quick-release mechanism.

[0014] When quick-release mechanisms are used to enable rapid attachment and removal of the watch band and body, the mechanism should be relatively small. When the quick-release mechanism is made of metal, its small size reduces the shielding effect on the watch body's antenna electromagnetic signals, ensuring the antenna can still receive and transmit electromagnetic signals normally, thus improving the antenna performance of the wearable device.

[0015] A quick-release mechanism is applied to the links of a watch strap, which may include multiple links connected in sequence. The quick-release mechanism is small in size, allowing it to be integrated into the link unit itself, and the strap length can be adjusted by increasing or decreasing the number of links.

[0016] In one alternative implementation, the central axis of the spring bar and the central axis of the elastic element are located in a first plane, which is perpendicular to a third direction. The first direction, the second direction, and the third direction are all perpendicular to each other. During button pressing, the torsional resistance on the spring bar is reduced, allowing the spring bar to move smoothly within the first groove of the base, thus reducing the possibility of the spring bar wobbling or tilting during pressing due to misalignment between the spring bar and the elastic element.

[0017] In one alternative implementation, the central axis of the button is located on a second plane, which is perpendicular to a third direction. The first and second planes coincide or are adjacent to each other. During button pressing, the torsional resistance on the button and spring bar can be reduced, allowing the button to move smoothly within the second groove of the base, and the spring bar to move smoothly within the first groove of the base. This reduces the likelihood of misalignment of the spring bar, elastic element, and button components causing the button and spring bar to wobble or tilt during pressing.

[0018] In one alternative implementation, when the button is in the first position, the button at least partially protrudes outside the second groove. A quick-release mechanism is applied between the watch strap and the watch case to enable quick attachment and removal of the strap. This quick-release mechanism is relatively small. It can be located at the end of the strap that connects to the watch case, positioned as close to the case as possible. The button protrudes outside the second groove, allowing the user to easily press the button with their fingertip, reducing the risk of the button accidentally contacting the bottom of the watch case and causing the strap to detach from the case when the strap rotates to that position.

[0019] In one alternative implementation, the sliding part and the mating part can be in a beveled sliding fit. Combined with an elastic element, this enables the button and spring bar to move in tandem.

[0020] In one alternative implementation, the sliding part and the mating part are in a beveled sliding fit, with both the sliding part and the mating part being beveled sections. Combined with an elastic element, this enables the button and spring bar to move in tandem.

[0021] In one alternative implementation, the sliding part and the mating part are in a sloped sliding fit, with the sliding part being the sloped section and the mating part being the rod section. Combined with an elastic element, this enables the button and spring bar to move in tandem.

[0022] In one alternative implementation, the sliding part and the mating part are in a beveled sliding fit, with the sliding part being the rod portion and the mating part being the beveled portion. Combined with an elastic element, this enables the button and spring bar to move in tandem.

[0023] In one optional implementation, the spring bar includes a first spring bar and a second spring bar, and the opening includes a first sub-hole and a second sub-hole. The first sub-hole, the first sliding groove, and the second sub-hole are sequentially connected along a first direction. The rod portion of the first spring bar passes through the first sub-hole, and the rod portion of the second spring bar passes through the second sub-hole. The sliding portions of the first spring bar and the second spring bar are arranged facing each other. An elastic element is compressed and disposed between the sliding portions of the first spring bar and the second spring bar. By using a button and the elastic element, the mounting ends of the two spring bars can be synchronously retracted or extended in opposite directions.

[0024] In one optional implementation, the mating portion includes a first sub-matting portion and a second sub-matting portion distributed along a first direction. The first sub-matting portion has a first mating surface, and the second sub-matting portion has a second mating surface. Along the pressing direction of the button, the distance between the first mating surface and the second mating surface gradually increases. The first mating surface and the sliding portion of the first spring bar are in sliding engagement, and the second mating surface and the sliding portion of the second spring bar are in sliding engagement. Both the first mating surface and the second mating surface can be inclined surfaces or arc surfaces.

[0025] In one alternative implementation, the distance between the first mating surface and the second mating surface gradually increases along the second direction from the second slide groove to the first slide groove. The sliding portion of the first spring bar has a first inclined surface, and the sliding portion of the second spring bar has a second inclined surface; the first and second inclined surfaces are arranged opposite to each other. The first mating surface and the first inclined surface are in sliding engagement, and the second mating surface and the second inclined surface are also in sliding engagement. The first mating surface and the first inclined surface can be in surface-to-surface contact. The second mating surface and the second inclined surface can also be in surface-to-surface contact.

[0026] When the button is pressed, the first mating surface abuts against the first inclined surface, causing the first spring bar to move inward, and the second mating surface abuts against the second inclined surface, causing the second spring bar to move inward. That is, the first spring bar and the second spring bar move towards each other, and the elastic element is compressed.

[0027] When the button is released, under the action of the elastic element, the first and second spring bars move in opposite directions, that is, the first and second spring bars move outward, the first inclined surface abuts against the first mating surface, and the second inclined surface abuts against the second mating surface, so that the button can pop up from the second slide groove.

[0028] In one alternative implementation, the sliding portion of the first spring bar has a first groove and a first inclined surface, the first inclined surface being the inner wall surface of the first groove near the elastic element. The sliding portion of the second spring bar has a second groove and a second inclined surface, the second inclined surface being the inner wall surface of the second groove near the elastic element. When the button is in the second position, the first sub-fitting part is located in the first groove, and the second sub-fitting part is located in the second groove, allowing the spring bar to be smaller in size along the second direction, resulting in a compact overall structure and a smaller footprint.

[0029] In one alternative implementation, the distance between the first mating surface and the second mating surface gradually increases along the second direction from the second slide groove to the first slide groove. The sliding portion of the first spring bar has a first extension rod, and the sliding portion of the second spring bar has a second extension rod. The first and second extension rods extend along a third direction, which is perpendicular to the first and second directions, respectively. The first mating surface and the first extension rod are in sliding engagement, as are the second mating surface and the second extension rod. The first mating surface and the first extension rod can have line-to-surface contact. The second mating surface and the second extension rod can also have line-to-surface contact.

[0030] When the button is pressed, the first mating surface abuts against the first extension rod, causing the first spring bar to move inward, and the second mating surface abuts against the second extension rod, causing the second spring bar to move inward. That is, the first spring bar and the second spring bar move towards each other, and the elastic element is compressed.

[0031] When the button is released, under the action of the elastic element, the first and second spring bars move in opposite directions, that is, the first and second spring bars move outward, the first extension rod abuts against the first mating surface, and the second extension rod abuts against the second mating surface, so that the button can pop up from the second slide groove.

[0032] In one alternative implementation, the sliding part and the mating part can have a curved sliding fit. Combined with an elastic element, this enables the button and spring bar to move in tandem.

[0033] In one alternative implementation, the sliding part and the mating part have an arc-shaped sliding fit, with the sliding part being the arc-shaped portion and the mating part being the rod portion. Combined with an elastic element, this enables the button and spring bar to move in tandem.

[0034] In one alternative implementation, the sliding part and the mating part have a curved surface sliding fit, with the sliding part being the rod portion and the mating part being the curved surface portion. Combined with an elastic element, this enables the button and spring bar to move in tandem.

[0035] In one alternative implementation, the base includes a first spring bar and a second spring bar, which are distributed on the base along a first direction. The first spring bar is movable relative to the base along the first direction, and an elastic element acts on the first spring bar, with a sliding engagement between the mating part of the button and the sliding part of the first spring bar. Alternatively, the elastic element does not act on the second spring bar, and there is no mating part on the button corresponding to the position of the second spring bar. The second spring bar is slidably mounted on the base, and another elastic element (such as a compression spring) acts on the second spring bar to push its end out of the base; or, the second spring bar is fixed to the base, and there is no movement of the second spring bar relative to the base.

[0036] The button and the first earpiece are linked, but the button and the second earpiece are not linked. Through the button and the elastic element, the mounting end of the first earpiece can be retracted or extended relative to the base opening. When the button is pressed, it causes the first earpiece to retract, but it does not cause the second earpiece to retract. When the button is in the second position and released, the elastic element acts on the first earpiece, causing it to extend beyond the base, but it does not act on the second earpiece to extend beyond the base.

[0037] In one alternative implementation, the end of the sliding part connected to the rod has a limiting surface, which abuts against the inner wall of the base to limit the position of the sliding part. This limits the farthest position of the rod extending out of the opening, preventing the spring bar from detaching from the base.

[0038] In one alternative implementation, the sliding part and the first groove have cross-sectional shapes that are adapted to each other along a first direction. This limits the movement of the sliding part along the first groove without rotation or tilting.

[0039] In one alternative implementation, the cross-sectional shape of both the sliding part and the first groove along the first direction can be rectangular or other non-circular.

[0040] In one alternative implementation, the elastic element can be a compression spring, a compression sheet, or other elastic element.

[0041] In one alternative implementation, the sliding part has a mounting part on the side facing away from the rod, and one end of the elastic element is located in the mounting part. This facilitates the positioning and mounting of the end of the elastic element in the sliding part, reduces the likelihood of the elastic element detaching from the sliding part during compression and elongation, and improves the reliability of the quick-release mechanism for long-term repeated use.

[0042] In one alternative implementation, the mounting part can be a positioning hole or a positioning post. For example, the mounting part can be a positioning hole, with one end of the elastic element inserted into the positioning hole. Alternatively, the mounting part can be a positioning post, with one end of the elastic element sleeved on the positioning post.

[0043] In one alternative implementation, the mating part has a limiting part. When the button is in the first position, the limiting part abuts against the inner wall of the base to confine the button to the second slide groove. The limiting part effectively limits the button's position, reducing the likelihood of the button dislodging from the second slide groove.

[0044] In one alternative implementation, the quick-release mechanism includes a base, a spring bar, an elastic element, and a button. The base has a first groove, an opening, and a second groove. The spring bar includes a sliding portion and a rod portion. The button has a mating portion that slides with the sliding portion. During the process of the button moving from a first position to a second position, i.e., the button being pressed, the mating portion abuts against the sliding portion to cause the sliding portion to move in a first direction, the mounting end gradually extends out of the opening, and the elastic element is stretched to store energy. When the button is pressed and in the released state, the elastic element shortens to release energy, the elastic element acts on the sliding portion to cause the sliding portion to move in the first direction, the mounting end gradually retracts to the opening, and the sliding portion abuts against the mating portion to move the button from the second position to the first position. The first position can be a pop-up position, and the second position can be a pressed position. The elastic element can be a tension spring or other tension elastic element. The end of the elastic element is connected to the sliding portion of the spring bar.

[0045] In one alternative implementation, the base includes a base and a cover plate. A first groove and an opening are formed in the base, and a second groove is formed in the cover plate. The first groove forms an opening on the surface of the base, and the cover plate is assembled at the opening. The base and cover plate can be arranged along a second direction. This structure is simple, easy to assemble, and has a good aesthetic appearance.

[0046] In one alternative implementation, the base has a first positioning part, and the cover plate has a second positioning part, which are interlocked. One of the first and second positioning parts is a groove, and the other is a protrusion; their interlocking allows for quick positioning and assembly of the cover plate onto the base.

[0047] In one alternative implementation, the cover and the base can be connected by adhesive bonding, fastener connection, or snap-fit ​​connection.

[0048] In one alternative implementation, the base has a groove filled with adhesive, and the cover plate and the base are bonded together by the adhesive. A reliable connection between the cover plate and the base is achieved through dispensing the adhesive.

[0049] In one alternative implementation, the cover plate and the base are connected by two fasteners located at opposite ends of the base along a first direction. The fasteners pass through the cover plate and are connected to the base, achieving a quick and reliable connection between the cover plate and the base.

[0050] In one alternative implementation, the cover plate and the base are connected by fasteners. The bottom surface of the first sliding groove has a connecting post that passes through the sliding portion along a second direction. Fasteners pass through the cover plate and are connected to the connecting post. The cover plate is reliably fixed to the base by fasteners (such as screws). The connecting post passes through the sliding portion or the second sliding portion, making the structure compact and occupying less space.

[0051] In one alternative implementation, the sliding portion of the first spring bar may have a first groove and a first inclined surface, the first inclined surface being used for sliding engagement with the first mating surface of the button. The sliding portion of the second spring bar may have a second groove and a second inclined surface, the second inclined surface being used for sliding engagement with the second mating surface of the button. Combined with an elastic element, the button and the spring bar are linked.

[0052] When assembling the spring bars to the base, the sliding parts of the first and second spring bars are inserted into the first groove of the base. One connecting post passes through the first groove, and the other connecting post passes through the second groove. The dimensions of the first and second inclined surfaces in the first direction are set to be relatively small, just enough to satisfy the sliding fit between the first inclined surface and the first mating surface, and the sliding fit between the second inclined surface and the second mating surface. The dimensions of the first and second spring bars in the first direction can be made small, resulting in a smaller quick-release mechanism and a compact overall structure.

[0053] In one alternative implementation, the base has a process groove. When the quick-release mechanism is applied to the watch strap, the retaining strap can be injection molded as an insert, with the quick-release mechanism acting as an insert to allow the material of the retaining strap to enter the process groove of the base, so that the base and the retaining strap material are tightly connected together to form an integral mechanism.

[0054] In one alternative implementation, the base includes two first half-shells distributed along a first direction. The two first half-shells are assembled to form the base, and each first half-shell has an opening. The two first half-shells form a first groove and a second groove. This structure is simple and easy to assemble.

[0055] In one alternative implementation, the base includes two second half-shells distributed along a third direction. The two second half-shells are assembled to form the base, and the two second half-shells enclose a first groove, an opening, and a second groove. This structure is simple and easy to assemble.

[0056] Secondly, this application provides a watch strap, including a fixing strap and the aforementioned quick-release mechanism, the quick-release mechanism being located at one end of the fixing strap. The mounting end of the spring bar is used to connect with the lugs of the watch body.

[0057] The watch body has lugs at both ends, and each lug has a shaft hole. When the mounting end extends out of the base, it can be inserted into the shaft hole of the lug to connect the strap to the watch body. When the mounting end retracts relative to the base, it can be separated from the shaft hole of the lug, thereby separating the strap from the watch body.

[0058] In one alternative implementation, the first direction can be the width direction of the fixed strip, and the second direction can be the thickness direction of the fixed strip.

[0059] Thirdly, embodiments of this application provide a watch strap comprising a plurality of sequentially connected link units, each link unit including the aforementioned quick-release mechanism. Each link unit has a connecting portion and a connecting groove distributed opposite each other along a third direction. A spring bar is located in the connecting portion. The link unit also has a first connecting hole and a second connecting hole, the first connecting hole, the connecting groove, and the second connecting hole being arranged sequentially along a first direction. In two adjacent link units, the connecting portion of the preceding link unit is disposed within the connecting groove of the following link unit, and the mounting end of the spring bar in the preceding link unit is connected to the first connecting hole or the second connecting hole of the following link unit.

[0060] The watch strap provided in this embodiment includes multiple sequentially connected link units. The quick-release mechanism is small in size and can be integrated as part of the link unit. When assembling two adjacent link units, the connecting part of the preceding link unit is located within the connecting groove of the following link unit, and the mounting end of the spring bar in the preceding link unit is connected to the first or second connecting hole of the following link unit, facilitating assembly. The strap length can be adjusted by increasing or decreasing the number of link units, providing a good user experience.

[0061] In one optional implementation, when the spring bar includes a first spring bar and a second spring bar, the mating part includes a first sub-matting part and a second sub-matting part distributed along a first direction. The first sub-matting part and the sliding part of the first spring bar are in sliding engagement, and the second sub-matting part and the sliding part of the second spring bar are in sliding engagement. Combined with an elastic element, the button and the spring bar are linked. When assembling two adjacent link units, the mounting end of the first spring bar can be connected to the corresponding first connecting hole, and the mounting end of the second spring bar can be connected to the corresponding second connecting hole, thus achieving the connection of the two link units, making the connection operation convenient.

[0062] In one alternative implementation, when the watch strap is used in a wearable device, the watch strap is detachably connected to the lugs of the watch body. The quick-release mechanism in the link unit at the end of the watch strap is connected and engaged with the lugs of the watch body. The mounting end of the spring bar in the quick-release mechanism at the end of the watch strap is inserted into the shaft hole of the lug, so that the watch strap can be connected to the watch body.

[0063] In one alternative implementation, the watch strap can be a single-bead strap, a zigzag strap, or a three-bead strap. The quick-release mechanism is compact and can be applied to various types of adjustable-length watch straps.

[0064] In one alternative implementation, the single-bead belt is formed by connecting beads in a single row. Each link unit of the single-bead belt consists of a single bead. Each link unit is a quick-release mechanism. The base of the quick-release mechanism has opposite connecting portions and connecting grooves. Spring bars are located at the connecting portions. A first connecting hole and a second connecting hole are located at the base. The first connecting hole, connecting groove, and second connecting hole are arranged sequentially along a first direction.

[0065] In one alternative implementation, the I-beam belt is formed by alternating I-beam beads and intermediate beads. Each link unit of the I-beam belt includes one I-beam bead and one intermediate bead. The intermediate bead is a quick-release mechanism. The I-beam bead has two opposite grooves. The intermediate bead is rotatably connected to one of the grooves of the I-beam bead, for example, by using a connecting shaft passing through the I-beam bead. A portion of the intermediate bead protrudes from this groove as a connecting part. The other groove of the intermediate bead serves as a connecting groove for the link unit. A spring bar is located at the connecting part. A first connecting hole and a second connecting hole are located on the I-beam bead. The first connecting hole, the connecting groove, and the second connecting hole are arranged sequentially along a first direction.

[0066] In one alternative implementation, the three-bead belt is formed by connecting three rows of beads. Each link unit of the three-bead belt includes three beads arranged along a first direction, with the middle bead serving as a quick-release mechanism. The base of the quick-release mechanism has opposite connecting portions and connecting grooves. Spring bars are located at the connecting portions. The bead on one side has a first connecting hole, and the bead on the other side has a second connecting hole; the first connecting hole, connecting groove, and second connecting hole are arranged sequentially along the first direction.

[0067] In one alternative implementation, when the button is in the first position, it is located within the second slide groove. The pressing surface of the button can be close to the opening of the second slide groove. When the user wears the wearable device, the button will not protrude outside the second slide groove, and the button will not exert pressure on the user, resulting in a good user experience.

[0068] In one alternative implementation, each link unit includes a first bead, a second bead, and a third bead arranged and connected sequentially along a first direction; the second bead is a quick-release mechanism. The second bead is offset from the first and third beads along a third direction. One end of the base along the third direction forms a connecting portion protruding relative to the first and third beads, and the other end of the base along the third direction, together with the first and third beads, forms a connecting groove. A first connecting hole is located on the side of the first bead facing the connecting groove, and a second connecting hole is located on the side of the third bead facing the connecting groove. Applying the quick-release mechanism to a three-bead strap results in a smaller quick-release mechanism, allowing it to function as the middle bead (i.e., the second bead) of the link unit. Adjusting the strap length by increasing or decreasing the number of link units provides a better user experience.

[0069] In one alternative implementation, the base may include a base plate and a cover plate. A first groove and an opening are formed in the base plate, and a second groove is formed in the cover plate. The first groove forms an opening on the surface of the base, and the cover plate is assembled at the opening. The cover plate and the base can be connected by a snap-fit ​​mechanism, achieving a reliable connection between the cover plate and the base, and facilitating the separation of the cover plate from the base.

[0070] In one alternative implementation, the first, second, and third beads in the same link unit are connected by a connecting shaft, thus maintaining the first, second, and third beads as a single integrated structure.

[0071] In one alternative implementation, the first, second, and third beads in the same link unit can be connected by two connecting shafts. Each connecting shaft has the first, second, and third beads sequentially threaded through it along a first direction. The two connecting shafts are arranged along a third direction, which allows the first, second, and third beads to remain as a single structure.

[0072] Fourthly, embodiments of this application provide a wearable device, including a watch body and a watch strap, the watch strap being detachably connected to the lugs of the watch body. Users can easily remove the watch strap from the watch body and assemble the watch strap onto the watch body, resulting in a good user experience.

[0073] In one alternative implementation, the watch body may include a middle frame and a bottom shell, with the bottom shell and screen located on opposite sides of the middle frame. The motherboard and battery, among other components, may be housed inside the middle frame. The antenna may be located inside or outside the middle frame. Attached Figure Description

[0116] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Although the description of this application is presented in conjunction with some embodiments, this does not mean that the features of this application are limited to this implementation. On the contrary, the purpose of describing the application in conjunction with embodiments is to cover other options or modifications that may arise based on the claims of this application. To provide a thorough understanding of this application, many specific details will be included in the following description. This application may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this application, some specific details will be omitted in the description. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0117] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0118] It should be understood that, in the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0119] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0120] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0121] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0122] See Figure 1 and Figure 2 This application provides a wearable device 1000, including a watch body 400 and a watch strap 200, the watch strap 200 being detachably connected to the lugs 410 of the watch body 400. Users can easily detach and assemble the watch strap 200 from the watch body 400, providing a good user experience. The wearable device 1000 can be a watch, a bracelet, etc.

[0123] Wearable device 1000 may include components such as a motherboard, battery, antenna, and screen. The motherboard is electrically connected to various electrical components, and components such as a processor may be mounted on the motherboard. The battery provides power to the various electrical components. The antenna is used to transmit and receive electromagnetic wave signals. The screen can be used to display images, prompts, etc. Understandably, wearable device 1000 may include more or fewer components, or combine some components, or separate some components.

[0124] The watch body 400 may include a middle frame and a bottom shell, with the bottom shell and screen respectively located on opposite sides of the middle frame. The middle frame and bottom shell can be assembled into an outer casing, but the outer casing is not limited to this. A motherboard and battery, among other components, may be housed inside the middle frame. The antenna may be located inside or outside the middle frame. It should be noted that this application embodiment uses an outer casing comprising a middle frame and a bottom shell as an example for illustration; it is understood that this application embodiment is not limited to this. For example, the outer casing may also include a front shell, a middle frame, and a bottom shell, with the front shell and bottom shell respectively located on opposite sides of the middle frame, and the front shell surrounding the screen. The front shell may be movably mounted to the middle frame or fixedly mounted to the middle frame.

[0125] See Figure 1 and Figure 2This application provides a watch strap 200, including a fixing strap 210 and a quick-release mechanism 100, the quick-release mechanism 100 being disposed at one end of the fixing strap 210. The fixing strap 210 can be a strap made of different materials such as adhesive tape, leather belt, or woven tape. Figure 3 , Figure 4 The quick-release mechanism 100 includes a base 110 and a spring bar 120. The spring bar 120 is disposed on the base 110 and has a mounting end 122a that can extend or retract relative to the base 110. The mounting end 122a of the spring bar 120 is used to connect with the lug 410 of the watch body 400.

[0126] The watch body 400 has lugs 410 at both ends (both ends of the middle frame), and each lug 410 has a shaft hole 411. (See also...) Figure 1 , Figure 2 When the mounting end 122a extends out of the base 110, it can be inserted into the shaft hole 411 of the lug 410, thus connecting the fixing strap 210 to the watch body 400. (See reference...) Figure 4 When the mounting end 122a is retracted relative to the base 110, combined with Figure 2 The mounting end 122a can be separated from the shaft hole 411 of the lug 410, thereby separating the fixing strap 210 from the watch body 400.

[0127] See Figures 3 to 6 This application provides a quick-release mechanism 100, including a base 110, spring bar 120, elastic element 130, and button 140. The base 110 has a first groove 111, an opening 112, and a second groove 113, which are combined with... Figure 7 The opening 112 and the first slide groove 111 are connected along the first direction A1, and the first slide groove 111 and the second slide groove 113 are connected along the second direction A2. The spring bar 120 includes a sliding part 121 and a rod part 122. The sliding part 121 is connected to one end of the rod part 122, and the other end of the rod part 122 is a mounting end 122a that passes through the opening 112. The sliding part 121 is slidably mounted in the first slide groove 111 along the first direction A1. An elastic element 130 is disposed in the first slide groove 111 and acts on the sliding part 121. The button 140 is slidably mounted in the second slide groove 113 along the second direction A2, so that in a first position (e.g., ... Figure 3 , Figure 7 (as shown) and the second position (as shown) Figure 4 , Figure 8 Switching between (as shown). Button 140 has a mating portion 141 that slides with sliding portion 121. During the movement of button 140 from the first position to the second position, the mating portion 141 abuts against sliding portion 121, causing sliding portion 121 to move along the first direction A1, and mounting end 122a gradually retracts to opening 112 (as shown). Figure 4 , Figure 8As shown in the diagram, during the process of button 140 moving from the second position to the first position, elastic element 130 acts on sliding part 121 to cause sliding part 121 to move along the first direction A1, mounting end 122a gradually extends out of opening 112, and sliding part 121 abuts against mating part 141 to cause button 140 to move from the second position to the first position (as shown in the diagram). Figure 3 , Figure 7 (As shown).

[0128] The first direction A1 and the second direction A2 can be perpendicular or not perpendicular (for example, the angle between the first direction A1 and the second direction A2 is 60° to 90°). When the quick-release mechanism 100 is applied between the watch strap 200 and the watch body 400 to achieve quick installation and removal of the watch strap 200, the first direction A1 can be the width direction of the fixed strap 210, and the second direction A2 can be the thickness direction of the fixed strap 210.

[0129] The quick-release mechanism 100 provided in this embodiment has a spring bar 120 disposed on a base 110. The sliding portion 121 of the spring bar 120 is slidably mounted on a first groove 111 of the base 110, and the rod portion 122 of the spring bar 120 passes through an opening 112 in the base 110. An elastic element 130 is disposed within the first groove 111 and acts on the sliding portion 121. A button 140 is slidably mounted on a second groove 113 of the base 110, so that in a first position (e.g., ... Figure 3 , Figure 7 (as shown) and the second position (as shown) Figure 4 , Figure 8 Switching between positions (as shown). During the movement of button 140 from the first position to the second position, the mating part 141 of button 140 pushes the sliding part 121 of spring bar 120, causing the sliding part 121 to move. The mounting end 122a gradually retracts into the opening 112, and the elastic element 130 gradually shortens to store energy. During the movement of button 140 from the second position to the first position, the elastic element 130 extends to release energy. The elastic element 130 pushes the sliding part 121 of spring bar 120, causing the sliding part 121 to move. The mounting end 122a gradually extends out of the opening 112, and the sliding part 121 abuts against the mating part 141, causing button 140 to move from the second position to the first position. This quick-release mechanism 100 has fewer parts and a simpler structure.

[0130] In some embodiments, see Figure 3 and Figure 4 During the process of pressing button 140, button 140 moves from the first position (e.g., Figure 3 , Figure 7 (As shown) Move to the second position (as shown) Figure 4 , Figure 8(As shown). When button 140 is pressed and in the released state, button 140 moves from the second position to the first position. Button 140 being in the released state means that button 140 is not subjected to pressing force.

[0131] The first position can be a pop-up position, and the second position can be a pressed position. It should be noted that the description of the first and second positions is not limited to "pop-up position" and "pressed position"; for example, "pop-up position" can also be called "initial position." With the base 110 stationary and the pressing surface of the button 140 facing upwards, the pressing surface of the button 140 is higher when it is in the first position than when it is in the second position.

[0132] The second slide groove 113 forms a slot 113a at its end opposite to the first slide groove 111. When the button 140 is in the first position, the pressing surface of the button 140 is close to the slot 113a of the second slide groove 113. By pressing the button 140, the button 140 moves inward, that is, the button 140 moves from the first position to the second position, and the distance between the pressing surface of the button 140 and the plane containing the slot 113a of the second slide groove 113 increases.

[0133] In some embodiments, see Figure 3 and Figure 4 The base 110 extends along the first direction A1, and the dimension of the base 110 along the first direction A1 is larger than the dimension of the base 110 along the third direction A3. The first direction A1, the second direction A2, and the third direction A3 are perpendicular to each other. The base 110 can be configured as a strip or a flat block that extends approximately along the first direction A1. The quick-release mechanism 100 has a compact overall structure and occupies less space.

[0134] In some embodiments, see Figure 3 and Figure 4 The dimension L1 (i.e. the width of the base 110) along the third direction A3 of the base 110 is less than or equal to 3 millimeters (mm). The spring bar 120, the elastic element 130 and the button 140 are arranged in the small-sized base 110, and the quick-release mechanism 100 has a compact overall structure and occupies less space.

[0135] For example, the dimension of the base 110 along the third direction A3 can be 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm or 3mm, or any range of two of the above values.

[0136] In some embodiments, see Figure 5 and Figure 8The sliding part 121 has a groove 1211. When the button 140 is in the second position, the mating part 141 is located in the groove 1211. This allows the spring bar 120 to be smaller in size along the second direction A2 and the third direction A3, resulting in a compact overall structure and a smaller footprint. The sliding part 121 can be roughly frame-shaped, with the groove 1211 formed inside the frame structure.

[0137] In some embodiments, see Figure 7 and Figure 9 The button 140 and the elastic element 130 are stacked along the second direction A2, and the elastic element 130 is compressed along the first direction A1. By making full use of the internal space of the base 110, the elastic element 130 and the button 140 are arranged in the small-sized base 110, so that the size of the base 110 along the third direction A3 can be made small. The quick-release mechanism 100 has a compact overall structure and occupies less space.

[0138] See Figure 1 , Figure 2 When the quick-release mechanism 100 is applied between the watch strap 200 and the watch body 400 to enable quick installation and removal of the watch strap 200, the quick-release mechanism 100 is relatively small in size. When the quick-release mechanism 100 is made of metal, the small size of the metal quick-release mechanism 100 results in less shielding of the electromagnetic wave signals from the antenna of the watch body 400, thus ensuring the normal reception and transmission of electromagnetic wave signals by the antenna of the watch body 400 and improving the antenna performance of the wearable device 1000.

[0139] The quick-release mechanism 100 is applied to the link units (not shown) of the watch strap 200, which may include multiple link units connected in sequence. The quick-release mechanism 100 is small in size, allowing it to be integrated as part of the link units. The length of the watch strap 200 can be adjusted by increasing or decreasing the number of link units, as will be described later.

[0140] In some embodiments, see Figure 9 The central axis A12 of the spring bar 120 and the central axis A13 of the elastic element 130 are located in the first plane B1, which is perpendicular to the third direction A3. The first direction A1, the second direction A2, and the third direction A3 are all perpendicular to each other. Figure 5 The central axis A12 of the spring ear rod 120 is the axis of the rod portion 122 of the spring ear rod 120.

[0141] The central axis A12 of the spring bar 120 and the central axis A13 of the elastic element 130 are arranged coplanarly, i.e., they are arranged on the first plane B1. During the pressing of the button 140, the torsional resistance on the spring bar 120 is reduced, allowing the spring bar 120 to move smoothly within the first groove 111 of the base 110. This reduces the likelihood of the spring bar 120 swaying or tilting during pressing due to misalignment between the spring bar 120 and the elastic element 130. Furthermore, it reduces the structural dimension along the third direction A3 to a certain extent.

[0142] In some embodiments, see Figure 9 The central axis A14 of button 140 is located on the second plane B2, which is perpendicular to the third direction A3. The first plane B1 and the second plane B2 are either coincident or adjacent. Figure 5 The central axis A14 of button 140 is the center line of button 140, which is parallel to the second direction A2 (i.e. the pressing direction of button 140).

[0143] The first plane B1, where the central axis A12 of the spring bar 120 and the central axis A13 of the elastic element 130 are located, and the second plane B2, where the central axis A14 of the button 140 is located, are arranged as close as possible, allowing for a small deviation distance. During the pressing of the button 140, the torsional resistance experienced by the button 140 and the spring bar 120 can be reduced, allowing the button 140 to move smoothly within the second slide groove 113 of the base 110, and the spring bar 120 to move smoothly within the first slide groove 111 of the base 110. This reduces the possibility of misalignment of the spring bar 120, the elastic element 130, and the button 140 causing the button 140 and the spring bar 120 to wobble or tilt when pressed.

[0144] In some embodiments, see Figure 3 and Figure 7 When button 140 is in the first position, button 140 at least partially protrudes outside the second slide groove 113. Combined with... Figure 1 The quick-release mechanism 100 is applied between the watch strap 200 and the watch body 400 to enable quick assembly and disassembly of the watch strap 200. The quick-release mechanism 100 is relatively small in size. The quick-release mechanism 100 can be located on the end of the fixed strap 210 that connects to the watch body 400, so that the quick-release mechanism 100 is as close to the watch body 400 as possible. The button 140 protrudes outside the second slide groove 113, making it convenient for users to press the button 140 with their fingertips. This reduces the risk of the button 140 accidentally contacting the bottom surface of the watch body 400 when the watch strap 200 rotates to the bottom surface of the watch body 400, causing the watch strap 200 to detach from the watch body 400, resulting in a better user experience.

[0145] In some embodiments, see Figure 5 , Figure 7 , Figure 8 The sliding part 121 and the mating part 141 can be a sloped sliding fit.

[0146] A sliding fit on an inclined plane can be a sliding contact fit between two inclined plane parts, or a sliding contact fit between an inclined plane part and a rod part. The first part moves along a first direction A1 and abuts against the second part, allowing the second part to move along a second direction A2. The second part moves along a second direction A2 and abuts against the first part, allowing the first part to move along a first direction A1.

[0147] The sliding part 121 and the mating part 141 are engaged by a beveled sliding fit, which, combined with the elastic element 130, enables the button 140 and the spring bar 120 to move in tandem. When the button 140 is pressed, the mating part 141 of the button 140 pushes the sliding part 121 of the spring bar 120 to move, causing the mounting end 122a of the spring bar 120 to retract at the opening 112, and the elastic element 130 to compress. When the button 140 is released, under the action of the elastic element 130, the elastic element 130 pushes the sliding part 121 to move, causing the mounting end 122a of the spring bar 120 to extend out of the opening 112, while the sliding part 121 pushes the mating part 141, causing the button 140 to automatically move from the second position to the first position.

[0148] For example, see Figure 5 , Figure 7 , Figure 8 The sliding part 121 and the mating part 141 are in a beveled sliding fit, with both parts being beveled. Combined with the elastic element 130, the button 140 and the spring bar 120 are linked. The left mating part 141 has a first mating surface 141a1, which is an inclined surface, and the left sliding part 121 has a first inclined surface 120a1. The first mating surface 141a1 and the first inclined surface 120a1 are in a sliding fit. The right mating part 141 has a second mating surface 141b1, which is an inclined surface, and the right sliding part 121 has a second inclined surface 120b1. The second mating surface 141b1 and the second inclined surface 120b1 are in a sliding fit.

[0149] For example, see Figure 10 In (a) and (b), the sliding part 121 and the mating part 141 are in a beveled sliding fit, with the sliding part 121 being the beveled portion and the mating part 141 being the rod portion. Combined with the elastic element 130, the button 140 and the spring bar 120 are linked. The left mating part 141 has a first mating rod 141a2, and the left sliding part 121 has a first inclined surface 120a1. The first mating rod 141a2 and the first inclined surface 120a1 are in a sliding fit. The right mating part 141 has a second mating rod 141b2, and the right sliding part 121 has a second inclined surface 120b1. The second mating rod 141b2 and the second inclined surface 120b1 are in a sliding fit.

[0150] For example, see Figure 11 In (a) and (b), the sliding part 121 and the mating part 141 are in a beveled sliding fit. The sliding part 121 is a rod portion, and the mating part 141 is a beveled portion. Combined with the elastic element 130, the button 140 and the spring bar 120 are linked. The mating part 141 on the left side has a first mating surface 141a1, and the sliding part 121 on the left side has a first extension rod 120a2. The first mating surface 141a1 and the first extension rod 120a2 are in a sliding fit. The mating part 141 on the right side has a second mating surface 141b1, and the sliding part 121 on the right side has a second extension rod 120b2. The second mating surface 141b1 and the second extension rod 120b2 are in a sliding fit.

[0151] In some embodiments, see Figure 5 , Figure 7 , Figure 8 The spring bar 120 includes a first spring bar 120a and a second spring bar 120b. The opening 112 includes a first sub-hole 112a and a second sub-hole 112b. The first sub-hole 112a, the first sliding groove 111, and the second sub-hole 112b are sequentially connected along a first direction A1. The rod portion 122 of the first spring bar 120a passes through the first sub-hole 112a, and the rod portion 122 of the second spring bar 120b passes through the second sub-hole 112b. The sliding portions 121 of the first spring bar 120a and the second spring bar 120b are arranged facing each other. An elastic member 130 is compressed and disposed between the sliding portions 121 of the first spring bar 120a and the second spring bar 120b.

[0152] The first spring bar 120a and the second spring bar 120b are both spring bars 120 that can move relative to the base 110 along the first direction A1. The button 140 is linked to both the first spring bar 120a and the second spring bar 120b. Through the button 140 and the elastic element 130, the mounting ends 122a of the two spring bars 120 can be synchronously retracted or extended in opposite directions. When the button 140 is pressed, it pushes the first spring bar 120a and the second spring bar 120b to move towards each other, and the elastic element 130 gradually shortens to store energy, combined with… Figure 8 The mounting end 122a of the first spring bar 120a gradually retracts into the first sub-hole 112a, and the mounting end 122a of the second spring bar 120b gradually retracts into the second sub-hole 112b. After the button 140 is released, the elastic element 130 gradually extends to release energy, and the elastic element 130 pushes the first spring bar 120a and the second spring bar 120b to move in opposite directions, combined with... Figure 7 When button 140 switches from the second position to the first position, the mounting end 122a of the first spring bar 120a gradually extends out of the first sub-hole 112a, and the mounting end 122a of the second spring bar 120b gradually extends out of the second sub-hole 112b.

[0153] In some embodiments, see Figure 5 , Figure 7 , Figure 8 The mating part 141 includes a first sub-matting part 141a and a second sub-matting part 141b distributed along the first direction A1. The first sub-matting part 141a has a first mating surface 141a1, and the second sub-matting part 141b has a second mating surface 141b1. In the pressing direction of the button 140 (i.e....) Figure 7 , Figure 8 In the second direction A2 (from top to bottom), the distance between the first mating surface 141a1 and the second mating surface 141b1 gradually increases. The first mating surface 141a1 and the sliding part 121 of the first spring bar 120a are in sliding engagement, and the second mating surface 141b1 and the sliding part 121 of the second spring bar 120b are in sliding engagement.

[0154] When button 140 is pressed, the first mating surface 141a1 abuts against the sliding portion 121 of the first spring bar 120a, causing the first spring bar 120a to move inward. Figure 7 (Moves to the right from center), the second mating surface 141b1 abuts against the sliding part 121 of the second spring bar 120b, causing the second spring bar 120b to move inward ( Figure 7 (Move from center to left), the elastic element 130 is compressed.

[0155] When button 140 is released, refer to... Figure 8 Under the action of the elastic member 130, the elastic member 130 pushes the sliding part 121 of the first spring bar 120a and the sliding part 121 of the second spring bar 120b to move in opposite directions, that is, the first spring bar 120a and the second spring bar 120b move outward. The sliding part 121 of the first spring bar 120a abuts against the first mating surface 141a1, causing the first sub-matting part 141a to move upward. The sliding part 121 of the second spring bar 120b abuts against the second mating surface 141b1, causing the second sub-matting part 141b to move upward. Thus, the button 140 moves from the second position to the first position.

[0156] The first mating surface 141a1 and the second mating surface 141b1 can both be inclined surfaces or arc surfaces, provided that the distance between the first mating surface 141a1 and the second mating surface 141b1 gradually increases along the second direction A2 from the second slide groove 113 to the first slide groove 111.

[0157] In some embodiments, see Figures 5 to 8Along the second direction A2 from the second groove 113 to the first groove 111, the distance between the first mating surface 141a1 and the second mating surface 141b1 gradually increases. The sliding portion 121 of the first spring bar 120a has a first inclined surface 120a1, and the sliding portion 121 of the second spring bar 120b has a second inclined surface 120b1. The first inclined surface 120a1 and the second inclined surface 120b1 are arranged opposite to each other. The first mating surface 141a1 and the first inclined surface 120a1 are in sliding engagement, and the second mating surface 141b1 and the second inclined surface 120b1 are in sliding engagement.

[0158] The first mating surface 141a1 and the first inclined surface 120a1 can be in surface-to-surface contact, with a large contact area. When the first mating surface 141a1 and the first inclined surface 120a1 slide in contact, either one can push the other to move relatively smoothly.

[0159] The second mating surface 141b1 and the second inclined surface 120b1 can be in surface-to-surface contact, with a large contact area. When the second mating surface 141b1 and the second inclined surface 120b1 are in sliding contact, either one can push the other to move relatively smoothly.

[0160] When button 140 is pressed, the first mating surface 141a1 abuts against the first inclined surface 120a1, causing the first spring bar 120a to move inward. Figure 7 (Move to the right from the center), the second mating surface 141b1 abuts against the second inclined surface 120b1, causing the second spring bar 120b to move inward ( Figure 7 (Move from center to left), that is, the first ear rod 120a and the second ear rod 120b move towards each other, and the elastic element 130 is compressed.

[0161] When button 140 is released, refer to... Figure 8 Under the action of the elastic element 130, the first spring bar 120a and the second spring bar 120b move in opposite directions, that is, the first spring bar 120a and the second spring bar 120b move outward, the first inclined surface 120a1 abuts against the first mating surface 141a1, and the second inclined surface 120b1 abuts against the second mating surface 141b1, so that the button 140 can pop up from the second slide groove 113.

[0162] For example, see Figure 5 , Figure 7The sliding portion 121 of the first spring bar 120a has a first groove 1211a and a first inclined surface 120a1, the first inclined surface 120a1 being the inner wall surface of the first groove 1211a near the inner wall surface of the elastic member 130. The sliding portion 121 of the second spring bar 120b has a second groove 1211b and a second inclined surface 120b1, the second inclined surface 120b1 being the inner wall surface of the second groove 1211b near the inner wall surface of the elastic member 130.

[0163] Combination Figure 8 When button 140 is in the second position, the first sub-fitting part 141a is located in the first slot 1211 and the second sub-fitting part 141b is located in the second slot 1211, which can make the size of spring bar 120 along the second direction A2 smaller, resulting in a compact overall structure and a smaller space occupied by the structure.

[0164] In other embodiments, see Figure 11 In (a) and (b), along the second direction A2 from the second groove 113 to the first groove 111, the distance between the first mating surface 141a1 and the second mating surface 141b1 gradually increases. The sliding portion 121 of the first spring bar 120a has a first extension rod 120a2, and the sliding portion 121 of the second spring bar 120b has a second extension rod 120b2. The first extension rod 120a2 and the second extension rod 120b2 extend along a third direction A3, which is perpendicular to the first direction A1 and the second direction A2, respectively. The first mating surface 141a1 and the first extension rod 120a2 are in sliding engagement, and the second mating surface 141b1 and the second extension rod 120b2 are in sliding engagement.

[0165] The first mating surface 141a1 and the first extension rod 120a2 can be in line-to-surface contact. When the first mating surface 141a1 and the first extension rod 120a2 are in sliding contact, either one can push the other to move relatively smoothly.

[0166] The second mating surface 141b1 and the second extension rod 120b2 can be in line-to-surface contact. When the second mating surface 141b1 and the second extension rod 120b2 are in sliding contact, either one can push the other to move relatively smoothly.

[0167] When button 140 is pressed, refer to... Figure 11 In (a), the first mating surface 141a1 abuts against the first extension rod 120a2, causing the first spring bar 120a to move inward. Figure 11 (Move to the right from the center), the second mating surface 141b1 abuts against the second extension rod 120b2, causing the second spring bar 120b to move inward ( Figure 11 (Move from center to left), that is, the first ear rod 120a and the second ear rod 120b move towards each other, and the elastic element 130 is compressed.

[0168] When button 140 is released, refer to... Figure 11 In (b), under the action of the elastic member 130, the first spring bar 120a and the second spring bar 120b move in opposite directions, that is, the first spring bar 120a and the second spring bar 120b move outward, the first extension rod 120a2 abuts against the first mating surface 141a1, and the second extension rod 120b2 abuts against the second mating surface 141b1, so that the button 140 can pop up from the second slide groove 113.

[0169] In other embodiments, see Figure 12 and Figure 13 The sliding part 121 and the mating part 141 can be a curved sliding fit.

[0170] A curved surface sliding fit can be a sliding contact fit between a curved surface portion and a rod portion, where the curved surface portion can be a convex or concave curved surface. The preceding portion moves along a first direction A1 and abuts against the following portion, enabling the following portion to move along a second direction A2. The following portion moves along a second direction A2 and abuts against the preceding portion, enabling the preceding portion to move along the first direction A1.

[0171] The sliding part 121 and the mating part 141 adopt an arc-surface sliding fit, combined with the elastic element 130, to achieve linkage between the button 140 and the spring bar 120. See [reference needed] for the case where the button 140 is pressed. Figure 12 In (a), the mating part 141 of the button 140 pushes the sliding part 121 of the spring bar 120 to move, causing the mounting end 122a of the spring bar 120 to retract at the opening 112, compressing the elastic element 130. When the button 140 is released, refer to... Figure 12 In (b), under the action of the elastic member 130, the elastic member 130 pushes the sliding part 121 to move, so that the mounting end 122a of the spring bar 120 extends out of the opening 112, and the sliding part 121 pushes the mating part 141, so that the button 140 automatically moves from the second position to the first position.

[0172] For example, see Figure 12 In (a) and (b), the sliding part 121 and the mating part 141 have an arc-shaped sliding fit, with the sliding part 121 being an arc-shaped portion and the mating part 141 being a rod portion. Combined with the elastic element 130, the button 140 and the spring bar 120 are linked. The mating part 141 on the left side has a first mating rod 141a2, and the sliding part 121 on the left side has a first arc-shaped surface 120a3. The first mating rod 141a2 and the first arc-shaped surface 120a3 are in sliding fit. The mating part 141 on the right side has a second mating rod 141b2, and the sliding part 121 on the right side has a second arc-shaped surface 120b3. The second mating rod 141b2 and the second arc-shaped surface 120b3 are in sliding fit.

[0173] For example, see Figure 13 In (a) and (b), the sliding part 121 and the mating part 141 have an arc-shaped sliding fit. The sliding part 121 is a rod portion, and the mating part 141 is an arc-shaped portion. Combined with the elastic element 130, the button 140 and the spring bar 120 are linked. The mating part 141 on the left side has a first mating surface 141a1, which is either a convex or concave arc surface. The sliding part 121 on the left side has a first extension rod 120a2. The first mating surface 141a1 and the first extension rod 120a2 are in sliding fit. The mating part 141 on the right side has a second mating surface 141b1, which is either a convex or concave arc surface. The sliding part 121 on the right side has a second extension rod 120b2. The second mating surface 141b1 and the second extension rod 120b2 are in sliding fit.

[0174] In some embodiments, the base 110 includes a first spring bar 120a and a second spring bar 120b, which are distributed on the base 110 along a first direction A1. The first spring bar 120a is movable relative to the base 110 along the first direction A1. An elastic element 130 acts on the first spring bar 120a, and the mating portion 141 of the button 140 and the sliding portion 121 of the first spring bar 120a are slidably engaged. The elastic element 130 does not act on the second spring bar 120b, and there is no mating portion 141 on the button 140 corresponding to the position of the second spring bar 120b. The second spring bar 120b can be slidably mounted on the base 110. Another elastic element (such as a compression spring) acts on the second spring bar 120b to push the end of the second spring bar 120b out of the base 110; or, the second spring bar 120b is fixed to the base 110 and does not move relative to the base 110.

[0175] Button 140 is linked to the first spring ear 120a, but not to the second spring ear 120b. Through button 140 and elastic element 130, the mounting end 122a of the first spring ear 120a can be retracted or extended relative to the opening 112 of the base 110. When button 140 is pressed, it causes the first spring ear 120a to retract, but it does not cause the second spring ear 120b to retract. When button 140 is in the second position and released, elastic element 130 acts on the first spring ear 120a, causing it to extend beyond the base 110, but it does not act on the second spring ear 120b, causing it to extend beyond the base 110.

[0176] In some embodiments, see Figure 5 and Figure 7The sliding part 121 has a limiting surface 1212 at one end connected to the rod part 122. The limiting surface 1212 is used to abut against the inner wall of the base 110 to limit the position of the sliding part 121. This limits the farthest position of the rod part 122 extending out of the opening 112, so that the spring bar 120 will not detach from the base 110.

[0177] In some embodiments, see Figure 5 , Figure 7 The sliding part 121 and the first slide groove 111 are adapted to each other in cross-sectional shape along the first direction A1. This limits the movement of the sliding part 121 along the first slide groove 111 without rotation or tilting. The cross-sectional shape of both the sliding part 121 and the first slide groove 111 along the first direction A1 can be rectangular or other non-circular shapes.

[0178] In some embodiments, see Figure 5 , Figure 7 , Figure 8 The elastic element 130 can be a compression spring, a compression sheet, or other elastic element. The elastic element 130 provides elastic force to the sliding portion 121 of the spring bar 120, and when the button 140 is in the released state, the elastic force can cause the mounting end 122a of the rod 122 to extend out of the opening 112.

[0179] In some embodiments, see Figure 5 and Figure 6 The sliding part 121 has a mounting part 1213 on the side opposite to the rod part 122, and one end of the elastic member 130 is provided in the mounting part 1213. This facilitates the positioning and mounting of the end of the elastic member 130 in the sliding part 121, reduces the likelihood of the elastic member 130 disengaging from the sliding part 121 during compression and elongation, and improves the reliability of the quick-release mechanism 100 for long-term repeated use.

[0180] The mounting part 1213 can be a positioning hole or a positioning post. For example, the mounting part 1213 can be a positioning hole, with one end of the elastic member 130 inserted into the positioning hole. Alternatively, the mounting part 1213 can be a positioning post, with one end of the elastic member 130 sleeved on the positioning post.

[0181] In some embodiments, see Figures 5 to 7 The mating part 141 has a limiting part 142. When the button 140 is in the first position, the limiting part 142 abuts against the inner wall of the base 110 to limit the button 140 to the second slide groove 113. The limiting part 142 limits the button 140, reducing the possibility of the button 140 dislodging from the second slide groove 113. The limiting part 142 can be a protrusion provided in the mating part 141.

[0182] In other embodiments, the quick-release mechanism 100 includes a base 110, a spring bar 120, an elastic element 130, and a button 140. The base 110 has a first groove 111, an opening 112, and a second groove 113. The spring bar 120 includes a sliding portion 121 and a rod portion 122. The button 140 has a mating portion 141 that slides with the sliding portion 121.

[0183] During the process of button 140 moving from the first position to the second position, that is, during the process of button 140 being pressed, mating part 141 abuts against sliding part 121 to make sliding part 121 move along the first direction A1, mounting end 122a gradually extends out of opening 112, and elastic element 130 is stretched to store energy.

[0184] When button 140 is pressed and in the released state, elastic member 130 shortens to release energy. Elastic member 130 acts on sliding part 121 to make sliding part 121 move along the first direction A1. Mounting end 122a gradually retracts to opening 112. Sliding part 121 abuts against mating part 141 to make button 140 move from the second position to the first position.

[0185] The first position can be a pop-up position, and the second position can be a pressed position. With the base 110 stationary and the pressing surface of the button 140 facing upwards, the pressing surface of the button 140 is higher in the first position than it is in the second position. The elastic element 130 can be a tension spring or other elastic element. The end of the elastic element 130 is connected to the sliding portion 121 of the spring bar 120.

[0186] There are several possible implementation methods when setting up the base 110. Three implementation methods are given as examples below.

[0187] The first implementation method of base 110: see Figures 5 to 7 The base 110 includes a base 114 and a cover plate 115. A first groove 111 and an opening 112 are formed in the base 114, and a second groove 113 is formed in the cover plate 115. The first groove 111 forms an opening 111a on the surface of the base 114, and the cover plate 115 is assembled at the opening 111a. The base 114 and the cover plate 115 can be arranged along the second direction A2.

[0188] The structure is simple, easy to assemble, and has a good appearance. During assembly, the spring bar 120 and the elastic element 130 are installed in the first groove 111 of the base 110, the button 140 is installed on the cover plate 115, and the cover plate 115 is fixed on the base 114, so that the mating part 141 of the button 140 abuts against the sliding part 121 of the spring bar 120.

[0189] In some embodiments, see Figures 5 to 7The base 114 has a first positioning part 1141, and the cover plate 115 has a second positioning part 1151. The first positioning part 1141 and the second positioning part 1151 are inserted into each other. One of the first positioning part 1141 and the second positioning part 1151 is a groove, and the other is a protrusion. The two are inserted into each other to realize the quick positioning and assembly of the cover plate 115 onto the base 114.

[0190] In some embodiments, see Figures 5 to 7 The cover plate 115 and the base 114 can be connected by adhesive bonding, fasteners, or snap-fit. These methods can achieve a reliable connection between the cover plate 115 and the base 114 and facilitate assembly.

[0191] In some embodiments, see Figure 1 and Figure 2 The base 114 has a groove filled with adhesive, and the cover plate 115 and the base 114 are bonded together by the adhesive. A reliable connection between the cover plate 115 and the base 114 is achieved by applying adhesive.

[0192] For example, a slot is provided on the base 114 outside the two ends of the first slide groove 111, and glue is applied to the two slots respectively, so that the cover plate 115 can be reliably fixed on the base 114.

[0193] In other embodiments, see Figures 14 to 16 The cover plate 115 and the base 114 are connected by fasteners 116. There are two fasteners 116, which are located at opposite ends of the base 114 along the first direction A1. The fasteners 116 pass through the cover plate 115 and are connected to the base 114.

[0194] The cover plate 115 is reliably secured to the base 114 using fasteners 116 (such as screws). The base 114 may have threaded holes, and the fasteners 116 are screws. The screws pass through the cover plate 115 and are threaded into the threaded holes of the base 114, achieving a quick and reliable connection between the cover plate 115 and the base 114. There may be one or more fasteners 116.

[0195] In other embodiments, see Figures 17 to 20 The cover plate 115 and the base 114 are connected by fasteners 116. The bottom surface of the first slide groove 111 has a connecting post 117. The connecting post 117 passes through the sliding part 121 along the second direction A2. The fasteners 116 pass through the cover plate 115 and are connected to the connecting post 117.

[0196] The cover plate 115 is reliably secured to the base 114 by fasteners 116 (such as screws). The connecting post 117 may have a threaded hole, and the fastener 116 is a screw, which passes through the cover plate 115 and is threaded into the threaded hole of the connecting post 117. The connecting post 117 passes through a sliding part 121 or a second sliding part 121, making the structure compact and occupying less space. There may be one or more fasteners 116.

[0197] In some embodiments, see Figure 17 , Figure 18 The sliding portion 121 of the first spring bar 120a may have a first groove 1211a and a first inclined surface 120a1, the first inclined surface 120a1 being used for sliding engagement with the first mating surface 141a1 of the button 140. The sliding portion 121 of the second spring bar 120b may have a second groove 1211b and a second inclined surface 120b1, the second inclined surface 120b1 being used for sliding engagement with the second mating surface 141b1 of the button 140. Combined with the elastic element 130, the button 140 and the spring bar 120 are linked.

[0198] When assembling the spring bar 120 to the base 110, the sliding portion 121 of the first spring bar 120a and the sliding portion 121 of the second spring bar 120b are inserted into the first groove 111 of the base 110. One connecting post 117 passes through the first groove 1211a, and the other connecting post 117 passes through the second groove 1211b. The dimensions of the first inclined surface 120a1 and the second inclined surface 120b1 in the first direction A1 are set to be relatively small, satisfying the sliding fit between the first inclined surface 120a1 and the first mating surface 141a1, and the sliding fit between the second inclined surface 120b1 and the second mating surface 141b1. In this way, the dimensions of the first spring bar 120 and the second spring bar 120b in the first direction A1 can be made small, the quick-release mechanism 100 has a smaller dimension in the first direction A1, and the overall structure is compact.

[0199] In some embodiments, see Figure 17 The base 110 has a process groove 118. Combined with... Figure 1 When the quick-release mechanism 100 is applied to the watch strap 200, the fixing strap 210 can be made by insert injection molding. The quick-release mechanism 100 acts as an insert, allowing the material of the fixing strap 210 to enter the process groove 118 of the base 110, so that the base 110 and the material of the fixing strap 210 are tightly connected together to form an integrated mechanism.

[0200] The second implementation of the base 110: The base 110 includes two first half-shells distributed along the first direction A1. The two first half-shells are assembled to form the base 110. Each first half-shell has an opening 112. The two first half-shells form a first sliding groove 111 and a second sliding groove 113. This structure is simple and easy to assemble. The two first half-shells can be connected by adhesive bonding, fastener connection, or snap-fit ​​connection. During assembly, the first spring bar 120a, the elastic element 130, and the button 140 are installed on one of the first half-shells, and the second spring bar 120b is installed on the other first half-shell. Then, the two first half-shells are assembled.

[0201] The third implementation of the base 110: The base 110 includes two second half-shells distributed along a third direction A3. The two second half-shells are assembled to form the base 110, and the two second half-shells form a first sliding groove 111, an opening 112, and a second sliding groove 113. This structure is simple and easy to assemble. The two second half-shells can be connected by adhesive bonding, fasteners, or snap-fit ​​connections. During assembly, the spring bar 120, the elastic element 130, and the button 140 are installed on one of the second half-shells, and then the other first half-shell is installed on the previous second half-shell.

[0202] Understandably, there are multiple possible implementation methods when setting the sliding part 121 and the mating part 141 in the quick-release mechanism 100. For example, the sliding part 121 and the mating part 141 can be mated by two inclined surfaces sliding contact, the inclined surface and the rod surface sliding contact, or the arc surface and the rod surface sliding contact.

[0203] When setting the number of spring bar 120 that are linked to button 140 in quick release mechanism 100, there can be one or two.

[0204] When setting the base 110 in the quick-release mechanism 100, there are several optional implementation methods. For example, the base 110 includes a base 114 and a cover plate 115, or the base 110 includes two first half-shells distributed along a first direction A1, or the base 110 includes two second half-shells distributed along a third direction A3.

[0205] The above options can be combined in any way to form multiple solutions for the quick-release mechanism 100.

[0206] See Figure 21In embodiments (a) to (c), this application provides a watch strap 300, including a plurality of sequentially connected link units 310, each link unit 310 including the quick-release mechanism 100 described above. Each link unit 310 has a connecting portion 311 and a connecting groove 312 distributed opposite to each other along a third direction A3. A spring bar 120 is located in the connecting portion 311.

[0208] Understandable, combined Figures 22 to 25 In the case where the ear rod 120 includes a first ear rod 120a and a second ear rod 120b, the mating part 141 includes a first sub-matting part 141a and a second sub-matting part 141b distributed along the first direction A1. The first sub-matting part 141a and the sliding part 121 of the first ear rod 120a are in sliding engagement, and the second sub-matting part 141b and the sliding part 121 of the second ear rod 120b are in sliding engagement. (See reference...) Figure 26 , Figure 27 Combined with the elastic element 130, the button 140 and the spring bar 120 are linked. When assembling two adjacent link units 310, the mounting end 122a of the first spring bar 120a can be connected to the corresponding first connecting hole 313, and the mounting end 122a of the second spring bar 120b can be connected to the corresponding second connecting hole 314, thus realizing the connection of the two link units 310, which is convenient for connection operation.

[0209] See Figure 28In (a) and (b), when the watch strap 300 is applied to the wearable device 1000, the watch strap 300 is detachably connected to the lug 410 of the watch body 400. The quick-release mechanism 100 in the link unit 310 at the end of the watch strap 300 is connected and engaged with the lug 410 of the watch body 400. That is, the mounting end 122a of the spring bar 120 in the quick-release mechanism 100 at the end of the watch strap 300 is inserted into the shaft hole 411 of the lug 410, so that the watch strap 300 can be connected to the watch body 400.

[0210] In some embodiments, see Figure 21 The watch strap 300 can be a single-bead strap, a zigzag strap, or a triple-bead strap. The quick-release mechanism 100 is small in size and can be applied to various types of adjustable-length watch straps 300.

[0211] See Figure 29 In (a) and (b), the single-bead belt, also known as a bamboo-joint belt, is made of a single row of beads connected together. The link unit 310 of the single-bead belt consists of a single bead. The link unit 310 is a quick-release mechanism 100. The base 110 of the quick-release mechanism 100 has opposing connecting portions 311 and connecting grooves 312. Spring bar 120 is located at the connecting portion 311. The first connecting hole 313 and the second connecting hole 314 are located at the base 110. The first connecting hole 313, the connecting groove 312, and the second connecting hole 314 are arranged sequentially along the first direction A1.

[0212] See Figure 30 In (a) to (c), the I-beam belt is formed by alternating I-beam beads 321 and intermediate beads 322. The link unit 310 of the I-beam belt includes one I-beam bead 321 and one intermediate bead 322. The intermediate bead 322 is a quick-release mechanism 100. The I-beam bead 321 has two opposite grooves 3211. The intermediate bead 322 is rotatably connected to one of the grooves 3211 of the I-beam bead 321, for example, by using a connecting shaft passing through the I-beam bead 321. A portion of the intermediate bead 322 protrudes from the groove 3211 as a connecting portion 311. The other groove 3211 of the intermediate bead 322 serves as a connecting groove 312 of the link unit 310. A spring bar 120 is located at the connecting portion 311. A first connecting hole 313 and a second connecting hole 314 are located in the I-beam bead 321. The first connecting hole 313, the connecting groove 312, and the second connecting hole 314 are arranged sequentially along the first direction A1.

[0213] See Figure 21 , Figure 23 , Figure 25The three-bead belt is composed of three rows of beads connected together. The link unit 310 of the three-bead belt includes three beads arranged along the first direction A1, with the middle bead serving as a quick-release mechanism 100. The base 110 of the quick-release mechanism 100 has opposite connecting portions 311 and connecting grooves 312. Spring bars 120 are located at the connecting portions 311. The bead on one side has a first connecting hole 313, and the bead on the other side has a second connecting hole 314. The first connecting hole 313, connecting groove 312, and second connecting hole 314 are arranged sequentially along the first direction A1.

[0214] In some embodiments, see Figure 23 (a) Figure 28 In (a), when button 140 is in the first position, button 140 is located within the second slide groove 113. The pressing surface of button 140 can be close to the opening 113a of the second slide groove 113. When the user wears the wearable device 1000, button 140 will not protrude from the second slide groove 113, and button 140 will not exert pressure on the user, resulting in a good user experience.

[0215] In some embodiments, see Figure 22 , Figure 23 , Figure 26 Each link unit 310 includes a first bead 315, a second bead 316, and a third bead 317 arranged and connected sequentially along a first direction A1; the second bead 316 is a quick-release mechanism 100. The second bead 316 is offset from the first bead 315 and the third bead 317 along a third direction A3. One end of the base 110 along the third direction A3 forms a connecting portion 311 that protrudes relative to the first bead 315 and the third bead 317. The other end of the base 110 along the third direction A3 and the first bead 315 and the third bead 317 form a connecting groove 312. A first connecting hole 313 is located on the side of the first bead 315 facing the connecting groove 312, and a second connecting hole 314 is located on the side of the third bead 317 facing the connecting groove 312.

[0216] The quick-release mechanism 100 is applied to a three-bead belt. Its small size allows it to function as the middle bead (i.e., the second bead 316) of the link unit 310. Combined with... Figure 21 , Figure 26 When assembling two link units 310, the connecting part 311 of the preceding link unit 310 is located in the connecting groove 312 of the following link unit 310. The mounting end 122a of the spring bar 120 in the preceding link unit 310 is connected to the first connecting hole 313 or the second connecting hole 314 of the following link unit 310, thus connecting the two link units 310. (See reference...) Figure 27When separating the two link units 310, pressing the button 140 of the quick-release mechanism 100 causes the mounting end 122a to disengage from the corresponding first connecting hole 313 or second connecting hole 314, thus separating the two link units 310. The length of the watch strap 300 can be adjusted by increasing or decreasing the number of link units 310, providing a good user experience.

[0217] In some embodiments, see Figure 22 The base 110 may include a base 114 and a cover plate 115. A first sliding groove 111 and an opening 112 are formed in the base 114, and a second sliding groove 113 is formed in the cover plate 115. The first sliding groove 111 forms an opening 111a on the surface of the base 114, and the cover plate 115 is assembled at the opening 111a. The cover plate 115 and the base 114 can be connected by a snap-fit ​​119, which can reliably connect the cover plate 115 and the base 114 and facilitate the separation of the cover plate 115 from the base 114.

[0218] In some embodiments, see Figure 22 , Figure 24 , Figure 25 The first bead 315, the second bead 316, and the third bead 317 in the same link unit 310 are connected by a connecting shaft 318, so that the first bead 315, the second bead 316, and the third bead 317 remain as a single structure.

[0219] For example, the first bead 315, the second bead 316, and the third bead 317 in the same link unit 310 can be connected by two connecting shafts 318. Each connecting shaft 318 sequentially passes through the first bead 315, the second bead 316, and the third bead 317 along a first direction A1. The two connecting shafts 318 are arranged along a third direction A3, which can keep the first bead 315, the second bead 316, and the third bead 317 as a single structure. One connecting shaft 318 can be connected to the first bead 315 and the third bead 317 by riveting, and the other connecting shaft 318 can be sequentially passed through the first bead 315, the second bead 316, and the third bead 317 and connected by screws.
