Description

A watch body, a wearable device, and a watch lug assembly.

[0001] This application claims priority to Chinese Patent Application No. 202411713706.2, filed with the State Intellectual Property Office of China on November 26, 2024, entitled "A Watch Body, Wearable Device and Watch Lug Assembly", and Chinese Patent Application No. 202411840200.8, filed with the State Intellectual Property Office of China on December 12, 2024, entitled "A Watch Body, Wearable Device and Watch Lug Assembly", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of wearable device technology, and more particularly to a watch body, a wearable device, and a watch lug assembly. Background Technology

[0003] In wearable devices (such as watches), the watch case has lugs at both ends, and the spring bars at the ends of the strap fasten into the lugs' connecting holes to attach the strap to the watch case. Improving the comfort of users wearing wearable devices is a challenge the industry needs to address. Summary of the Invention

[0004] This application provides a watch body, a wearable device, and a watch lug assembly, which allows the watch strap to fit more closely to the user's wrist, improving the user's wearing comfort.

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

[0006] In a first aspect, embodiments of this application provide a watch body, including a watch case and a lug assembly. The watch case has a mounting portion with a fixing hole. The lug assembly passes through the fixing hole and is rotatable about the axis of the fixing hole. The lug assembly has a first connecting hole and a second connecting hole facing each other, which are used for connecting and engaging with a watch strap.

[0007] The watch body provided in this embodiment has a mounting hole in the case. The lug assembly passes through the mounting hole, allowing it to rotate around the axis of the mounting hole and connect to the mounting part of the case. When the watch body and strap are assembled to form a wearable device, the strap can rotate relative to the lug assembly, and the lug assembly can rotate relative to the case. There are two free rotation points corresponding to the connection position between the strap and the case. The strap fits the user's wrist more closely, improving wearing comfort. The watch body and wearable device can adapt to people with different wrist sizes.

[0008] In one alternative implementation, the mounting portion may be cylindrical and located at the end of the watch case. A portion of the lug assembly passes through a mounting hole in the mounting portion. The portion of the lug assembly exposed outside the mounting portion is bent, such as in a J-shape or L-shape.

[0009] In one alternative implementation, the lug assembly can be made of stainless steel, aluminum alloy, titanium alloy, etc.

[0010] In one alternative implementation, the mounting portion can be cylindrical, with the mounting portion elongated along the axial dimension of the fixing hole to deepen the fixing hole, enabling the lug assembly to rotate stably relative to the mounting portion.

[0011] In one alternative implementation, the watch case has mounting parts at both ends, each mounting part can be connected to a lug assembly, and each lug assembly is connected to a strap connection structure to assemble a wearable device.

[0012] In one alternative implementation, the lug assembly includes a first connecting lug and a second connecting lug. The first connecting lug includes a first shaft portion and a first connecting portion. The first shaft portion has a first end and a second end opposite to each other. The first connecting portion is connected to the first end. The first shaft portion is at least partially located within a fixing hole and can rotate about the axis of the fixing hole. The second connecting lug is mounted on the second end. The first connecting hole is located in the first connecting portion, and the second connecting hole is located in the second connecting lug. This design using a first connecting lug and a second connecting lug is easy to manufacture and easy to assemble into the mounting portion of the watch case, ensuring that the lug assembly does not detach from the watch case. The lug assembly can rotate relative to the mounting portion about the axis of the fixing hole.

[0013] In one alternative implementation, the first shaft portion and the first connecting portion of the first connecting ear are integral structures. The integrally structured first connecting ear has high strength, is not easily damaged, and is reliable and durable.

[0014] In one alternative implementation, the first shaft portion and the first connecting portion in the first connecting lug are an assembly structure. This enables a rotatable connection between the lug assembly and the mounting portion.

[0015] In one alternative implementation, the first shaft portion passes through the fixing hole, while the first connecting portion and the second connecting lug are both located outside the fixing hole. This reduces the number of assembly connection points, making assembly convenient and quick, and minimizing machining and assembly tolerances, thus reducing the amount of wobble when the lug assembly rotates.

[0016] In one alternative implementation, the first connecting lug includes a first shaft portion and a first connecting portion. The first shaft portion has a first end and a second end opposite to each other. The first connecting portion is connected to the first end. The first shaft portion is at least partially located within a fixing hole and is rotatable about the axis of the fixing hole. The second connecting lug includes a second shaft portion and a second connecting portion. The second shaft portion has a third end and a fourth end opposite to each other. The second connecting portion is connected to the third end. The second shaft portion is at least partially located within a fixing hole. The fourth end and the second end are both located within the fixing hole and are connected to each other. The first connecting portion and the second connecting portion are both located outside the fixing hole. The second connecting hole is located within the second connecting portion. This design reduces the number of assembly connection points, making assembly convenient and quick. It also minimizes machining and assembly tolerances, resulting in less wobble during rotation of the lug assembly.

[0017] In one alternative implementation, the second end of the first shaft portion and the fourth end of the second shaft portion can be connected by fasteners (such as screws), riveting, bonding, welding, or tight fitting. This enables a reliable connection between the first connecting lug and the second connecting lug.

[0018] In one alternative implementation, both the fourth end and the second end are located within the fixing hole and are connected to each other. The mounting part has a mounting port communicating with the fixing hole, corresponding to the position where the first shaft part and the second shaft part are connected. This facilitates operation at the mounting port to achieve the connection between the first shaft part and the second shaft part.

[0019] In one alternative implementation, the outer peripheral surface of the first shaft portion of the first connecting ear has a threaded hole, and the second connecting ear has a through hole. The second end of the first shaft portion is inserted into the mounting hole of the second connecting ear, and a screw is inserted through the through hole and threaded into the threaded hole of the first shaft portion, with the screw head located inside the through hole of the second connecting ear, thereby fixing the first connecting ear and the second connecting ear together.

[0020] In one alternative implementation, the second end of the first shaft portion is inserted into the mounting hole of the second connecting ear, and glue is applied between the second end and the wall of the mounting hole to achieve a fixed connection between the first connecting ear and the second connecting ear.

[0021] In one alternative implementation, a rivet is provided at the connection position between the first shaft portion and the second connecting ear in the first connecting ear, and the first connecting ear and the second connecting ear are fixedly connected by the rivet.

[0022] In one alternative implementation, the second end of the first shaft portion of the second connecting ear and the first connecting ear are inserted into each other and connected by their surfaces. The first shaft portion has a non-circular cross-section, which can be racetrack-shaped, D-shaped, rectangular, etc. The first connecting ear and the second connecting ear can rotate synchronously about the axis of the fixing hole, so that the first connecting hole of the first connecting ear and the second connecting hole of the second connecting ear are directly opposite each other, so that the connecting structure of the watch strap (such as spring bar) can be fastened to the first connecting hole and the second connecting hole.

[0023] In one alternative implementation, the second connecting ear has a mounting hole, and a second end can be inserted into the mounting hole, with the second end and the mounting hole being connected by a profile. The second end of the first shaft portion of the first connecting ear is inserted into the mounting hole of the second connecting ear, achieving synchronous rotational connection between the first and second connecting ears.

[0024] In one alternative implementation, the second end of the first shaft portion has a plug-in section, the cross-sectional shapes of which are adapted to those of the plug-in section and the mounting hole. By inserting the plug-in section of the first shaft portion into the mounting hole, the surface connection between the first connecting lug and the second connecting lug can be achieved.

[0025] In one alternative implementation, the second end has a mounting hole, and one end of the second connecting ear can be inserted into the mounting hole. The end of the second connecting ear and the mounting hole are connected by a profile. By inserting one end of the second connecting ear into the mounting hole at the second end of the first shaft portion in the first connecting ear, synchronous rotational connection between the first connecting ear and the second connecting ear is achieved.

[0026] In one alternative implementation, an elastic ring is fitted onto the first shaft portion, and the elastic ring is sandwiched between the inner wall of the fixing hole and the first shaft portion. The rotation of the lug assembly is damped by a certain amount of force, achieving smooth and stable rotation of the lug assembly, avoiding unpleasant noises and shaking caused by a clearance fit between the first shaft portion and the inner wall of the fixing hole, and reducing wear caused by long-term contact between the first shaft portion and the inner wall of the fixing hole.

[0027] In one alternative implementation, the elastic ring can be made of silicone, fluororubber, nitrile rubber, etc.

[0028] In one alternative implementation, the elastic ring can be O-shaped, D-shaped, or similar.

[0029] In one alternative implementation, the first shaft portion has a positioning groove, and an elastic ring is disposed in the positioning groove. This keeps the elastic ring in the first shaft portion and prevents it from easily detaching, thus improving the reliability of the assembly structure.

[0030] In one alternative implementation, the first shaft portion has two spaced-apart positioning grooves, each groove being provided with an elastic ring. The two elastic rings, clamped between the first shaft portion and the inner wall of the fixing hole, allow the lug assembly to rotate stably relative to the mounting portion.

[0031] In one alternative implementation, the damping feel of the lug assembly during rotation can be adjusted by changing the number of elastic rings or the interference fit.

[0032] In one alternative implementation, lubricating oil can be applied between the first shaft and the inner wall of the fixing hole. By changing the amount of oil applied, the damping feel of the rotating lug assembly can be adjusted.

[0033] In one alternative implementation, a rotation limiting structure is provided between the wall of the fixing hole and the lug assembly to limit the rotation range of the lug assembly relative to the mounting part. This facilitates the insertion of the strap connection structure (such as spring bars) into the first and second connection holes, and also prevents the lug assembly from rotating and hitting the front or back of the watch case in the event of a drop, thus avoiding impact damage to the bezel or case back.

[0034] In one alternative implementation, the lug assembly has a first limit position and a second limit position, and the lug assembly is rotatable between the first limit position and the second limit position. When the lug assembly is in the first limit position, the lug assembly is parallel to the front of the watch case, or the lug assembly forms a 90° angle or other value with the front of the watch case. When the lug assembly is in the second limit position, the lug assembly forms a 90° angle or other value with the back of the watch case. The first and second limit positions of the lug assembly can be set as needed.

[0035] In one alternative implementation, the lug assembly can rotate relative to the watch case within an angle range of 0° to 90°, providing a wide range of motion, adapting to people with different wrist sizes, and offering good wearing comfort.

[0036] In one alternative implementation, when the lugs are at a 0° position relative to the case, the lugs are parallel to the back of the case. When the lugs are at a 90° position relative to the case, the lugs are perpendicular to the back of the case.

[0037] In one alternative implementation, the lug assembly is rotated to a position parallel to the front of the watch case to prevent the lug assembly from rotating freely, thus facilitating the assembly of the strap connection structure into the first and second connection holes of the lug assembly.

[0038] In one alternative implementation, the rotation limiting structure includes an arc-shaped groove and a limiting part. One of the arc-shaped groove and the limiting part is disposed on the wall of the fixing hole, and the other is disposed on the first shaft part or the second connecting ear in the first connecting ear. The limiting part can slide within the arc-shaped groove. By cooperating with the arc-shaped groove and the limiting part, the rotation range of the lug assembly can be limited.

[0039] In one alternative implementation, the limiting part can be set as an arc segment.

[0040] In one alternative implementation, the arcuate groove has two first mating surfaces distributed circumferentially opposite to each other. The limiting portion also has two first mating surfaces distributed circumferentially opposite to each other. Two second mating surfaces of the limiting portion are located between the two first mating surfaces of the arcuate groove. The two second mating surfaces of the limiting portion correspond one-to-one with the two first mating surfaces of the arcuate groove. When one of the second mating surfaces of the limiting portion abuts against the corresponding first mating surface of the arcuate groove, the lug assembly is defined at a first extreme position. When the other second mating surface of the limiting portion abuts against the corresponding first mating surface of the arcuate groove, the lug assembly is defined at a second extreme position.

[0041] In one alternative implementation, the limiting part is located near the first connecting part of the first shaft part, and the arc-shaped groove is located on the wall of the fixing hole, so that the limiting part can slide within the arc-shaped groove.

[0042] In one alternative implementation, the limiting part is disposed on the wall of the fixing hole, and the arc-shaped groove is disposed on the first shaft part near the first connecting part, so that the limiting part can slide within the arc-shaped groove.

[0043] In one alternative implementation, a limiting part is provided in the second connecting ear, and an arc-shaped groove is provided at the second end of the first shaft part, allowing the limiting part to slide within the arc-shaped groove.

[0044] In one alternative implementation, a limiting part is disposed at the second end of the first shaft part, and an arc-shaped groove is disposed at the second connecting ear, allowing the limiting part to slide within the arc-shaped groove.

[0045] In one alternative implementation, the outer surface of the first connecting part has a first guide groove, which communicates with a first connecting hole. During assembly, the connecting structure of the watch strap (such as spring bars) is guided by the first guide groove and can smoothly slide into the first connecting hole, achieving quick installation.

[0046] In one alternative implementation, the outer surface of the second connecting lug has a second guide groove, which communicates with the second connecting hole. During assembly, the strap's connecting structure (such as a spring bar) is guided by the second guide groove and can smoothly slide into the second connecting hole, enabling quick installation.

[0047] In one alternative implementation, when the plane of the lug assembly is parallel to the front of the watch case, the first guide groove can be located on the side of the first connecting part facing away from the front of the watch case, and the second guide groove can be located on the side of the second connecting part facing away from the front of the watch case. When the user wears the wearable device, the first and second guide grooves are not visible, giving the wearable device a better aesthetic appeal.

[0048] In one alternative implementation, the mounting portion is cylindrical and has two opposing end faces. A first connecting lug has a first limiting surface, which faces one end face of the mounting portion. When the first connecting lug is assembled into the watch case, the first limiting surface abuts against one end face of the mounting portion to define the relative position of the first connecting lug and the mounting portion.

[0049] In one alternative implementation, the second connecting lug has a second limiting surface that faces one end face of the mounting portion. When the second connecting lug is assembled onto the watch case, the second limiting surface abuts against one end face of the mounting portion to define the relative position of the second connecting lug and the mounting portion.

The case has a mounting portion, and the lug assembly has a first connecting hole and a second connecting hole facing each other. The watch strap's connecting structure is detachably connected to the mounting portion of the case, and the connecting structure is fastened to the first connecting hole and the second connecting hole.

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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] Referring to Figure 1, in a wearable device 1 of the related art, lugs 1b are fixedly disposed at both ends of a watch case 1a, and the lugs 1b cannot rotate relative to the watch case 1a. A watch strap is connected to the lugs 1b to assemble the wearable device 1. When the user wears the wearable device 1, there is a certain gap between the area of ​​the watch strap near the lugs 1b and the user's wrist, making it difficult for the watch strap to fit snugly against the user's wrist, resulting in discomfort. It is suitable for a limited number of wrist sizes, and the longer lugs 1b are not suitable for users with small wrists.

[0103] Referring to Figures 2 and 3, this application embodiment provides a wearable device 1000, including a watch body 100 and a watch strap 200. The watch body 100 includes a case 10 and a lug assembly 20. The case 10 has a mounting portion 11, and the lug assembly 20 has a first connecting hole 211 and a second connecting hole 221 facing each other. The connecting structure 201 of the watch strap 200 is detachably connected to the mounting portion 11 of the case 10, and the connecting structure 201 is fastened to the first connecting hole 211 and the second connecting hole 221.

[0104] The wearable device 1000 can be a watch, bracelet, or similar device. The watch case 10 is the main body of the wearable device 1000 and can house various components such as a display screen, circuit board, and sensors. In the case where the wearable device 1000 is a watch, the watch case 10 can be the watch's frame.

[0105] The lug assembly 20 is the part detachably connected to the watch strap 200. The connection structure 201 of the watch strap 200 can be a spring bar at the end of the watch strap 200 or a buckle structure at the end of the watch strap 200. These methods allow the watch strap 200 to be detachably connected to the lug assembly 20. When the watch strap 200 is connected to the lug assembly 20, the watch strap 200 can rotate relative to the watch case 100.

[0106] In some embodiments, referring to Figures 2 and 3, the watch case 10 has mounting portions 11 at both ends, each mounting portion 11 can be connected to a lug assembly 20, and each lug assembly 20 is connected to a connecting structure 201 of a watch strap 200 to assemble a wearable device 1000. The two watch straps 200 can be connected by means of a buckle or the like, and the wearable device 1000 is bound to the user's wrist by the two watch straps 200.

[0107] Referring to Figures 4 to 6, this application embodiment provides a watch body 100, including a watch case 10 and a lug assembly 20. The watch case 10 has a mounting portion 11, and the mounting portion 11 has a fixing hole 111. The lug assembly 20 passes through the fixing hole 111. Referring to Figures 7(a) to (c), the lug assembly 20 can rotate about the axis A1 of the fixing hole 111. The lug assembly 20 has a first connecting hole 211 and a second connecting hole 221 facing each other. Referring to Figure 3, the first connecting hole 211 and the second connecting hole 221 are used to connect and cooperate with the watch strap 200.

[0108] The watch body 100 provided in this application embodiment has a mounting portion 11 with a fixing hole 111. The lug assembly 20 is inserted through the fixing hole 111, allowing the lug assembly 20 to be rotatably connected to the mounting portion 11 of the watch body 10 around the axis A1 of the fixing hole 111. When the watch body 100 and the watch strap 200 are assembled to form a wearable device 1000, the watch strap 200 can rotate relative to the lug assembly 20, and the lug assembly 20 can rotate relative to the watch body 10. There are two free rotation points corresponding to the connection position of one watch strap 200 and the watch body 10. The watch strap 200 fits the user's wrist more closely, improving the user's wearing comfort. The watch body 100 and the wearable device 1000 can adapt to people with different wrist sizes.

[0109] In some embodiments, referring to Figures 4 and 5, the mounting portion 11 may be cylindrical and located at the end of the watch case 10. A portion of the lug assembly 20 passes through the fixing hole 111 of the mounting portion 11. Referring to Figure 3, the portion of the lug assembly 20 exposed outside the mounting portion 11 is bent, such as J-shaped or L-shaped. The watch body 100 and wearable device 1000 of this embodiment have a certain aesthetic appeal and a good appearance. The lug assembly 20 may be made of stainless steel, aluminum alloy, titanium alloy, etc.

[0110] In some embodiments, referring to Figures 4 and 5, the mounting portion 11 may be cylindrical. The greater the depth of the fixing hole 111 in the mounting portion 11, the greater the mating length between the lug assembly 20 and the fixing hole 111. By lengthening the mounting portion 11 along the axial dimension of the fixing hole 111 and deepening the fixing hole 111, the lug assembly 20 can rotate stably relative to the mounting portion 11.

[0111] In some embodiments, referring to Figures 4 to 6, the lug assembly 20 includes a first connecting lug 21 and a second connecting lug 22. The first connecting lug 21 includes a first shaft portion 212 and a first connecting portion 213. The first shaft portion 212 has a first end 212a and a second end 212b opposite to each other. The first connecting portion 213 is connected to the first end 212a. Referring to Figures 8 and 9, the first shaft portion 212 is at least partially located in the fixing hole 111 and can rotate about the axis A1 of the fixing hole 111. The second connecting lug 22 is installed on the second end 212b. The first connecting hole 211 is located in the first connecting portion 213, and the second connecting hole 221 is located in the second connecting lug 22.

[0112] The assembly scheme using the first connecting lug 21 and the second connecting lug 22 is easy to manufacture and easy to assemble into the mounting part 11 of the watch case 10, so that the lug assembly 20 does not detach from the watch case 10, and the lug assembly 20 can rotate relative to the mounting part 11 about the axis A1 of the fixing hole 111.

[0113] There are several possible implementation methods for setting the first connecting ear 21 and the second connecting ear 22. These can be a two-stage asymmetric assembly structure, a two-stage symmetric assembly structure, or a three-stage assembly structure.

[0114] In some embodiments, referring to Figures 4 to 6, the first connecting ear 21 and the second connecting ear 22 adopt a two-stage asymmetrical assembly structure: the first shaft portion 212 and the first connecting portion 213 in the first connecting ear 21 are an integral structure. The first shaft portion 212 passes through the fixing hole 111, and the first connecting portion 213 and the second connecting ear 22 are both located outside the fixing hole 111.

[0115] The first connecting lug 21, with its integrated structure, has high strength, is not easily damaged, and is reliable and durable. During assembly, the first shaft portion 212 is inserted into the fixing hole 111 of the mounting portion 11, so that the second connecting lug 22 and the second end 212b of the first shaft portion 212 are fixedly connected. The number of assembly connection points is small, making assembly convenient and quick. The machining and assembly tolerances are small, resulting in less wobble when the lug assembly 20 rotates.

[0116] In some embodiments, referring to Figures 4 to 6, the second connecting ear 22 and the second end 212b of the first shaft portion 212 can be connected by fasteners (such as screws), riveting, bonding, welding, or tight fitting. These methods enable a reliable connection between the first connecting ear 21 and the second connecting ear 22.

[0117] For example, referring to Figures 4 to 6, the outer peripheral surface of the first shaft portion 212 of the first connecting ear 21 has a threaded hole, and the second connecting ear 22 has a through hole. The second end 212b of the first shaft portion 212 is inserted into the mounting hole 2231 of the second connecting ear 22. A screw 23 is inserted through the through hole and threaded into the threaded hole of the first shaft portion 212. The head of the screw 23 is located in the through hole of the second connecting ear 22, which can fix the first connecting ear 21 and the second connecting ear 22 together.

[0118] For example, the second end 212b of the first shaft portion 212 is inserted into the mounting hole 2231 of the second connecting ear 22, and glue is applied between the second end 212b and the wall of the mounting hole 2231, so that the first connecting ear 21 and the second connecting ear 22 are fixedly connected by the glue.

[0119] For example, a rivet is provided at the connection position between the first shaft portion 212 and the second connecting ear 22 in the first connecting ear 21, and the first connecting ear 21 and the second connecting ear 22 are fixedly connected by the rivet.

[0120] To facilitate the positioning and assembly of the first connecting ear 21 and the second connecting ear 22, in some embodiments, referring to Figures 4, 5, 8, and 9, the second connecting ear 22 and the second end 212b of the first shaft portion 212 in the first connecting ear 21 are inserted into each other and connected by a profile. The profile connection is formed by the mating of a non-circular cross-section shaft with the mounting hole 2231 of a correspondingly shaped part. The non-circular cross-section can be racetrack-shaped, D-shaped, rectangular, etc.

[0121] When assembling the first connecting ear 21 and the second connecting ear 22, the two are inserted and connected in shape, which limits the first connecting ear 21 and the second connecting ear 22 to a predetermined relative position. The first connecting ear 21 and the second connecting ear 22 can rotate synchronously around the axis A1 of the fixing hole 111, so that the first connecting hole 211 of the first connecting ear 21 and the second connecting hole 221 of the second connecting ear 22 are directly opposite each other. Referring to Figure 3, the connecting structure 201 (such as spring bar) of the watch strap 200 can be fastened to the first connecting hole 211 and the second connecting hole 221.

[0122] There are optional implementation methods when setting the first connecting ear 21 and the second connecting ear 22 to be connected.

[0123] The first method of achieving the surface connection between the first connecting ear 21 and the second connecting ear 22 is as follows: Referring to Figures 4 to 6, the second connecting ear 22 has a mounting hole 2231, and the second end 212b can be inserted into the mounting hole 2231, with the second end 212b and the mounting hole 2231 forming a surface connection. The second end 212b of the first shaft portion 212 in the first connecting ear 21 is inserted into the mounting hole 2231 of the second connecting ear 22, achieving synchronous rotational connection between the first connecting ear 21 and the second connecting ear 22.

[0124] For example, the second end 212b of the first shaft portion 212 has a plug-in section 2121, and the cross-sectional shapes of the plug-in section 2121 and the mounting hole 2231 are adapted to each other, both being racetrack-shaped. By inserting the plug-in section 2121 of the first shaft portion 212 into the mounting hole 2231, the surface connection between the first connecting ear 21 and the second connecting ear 22 can be achieved.

[0125] The second method for achieving the surface connection of the second connecting ear 22 and the second connecting ear 22 is as follows: the second end 212b has a mounting hole, and one end of the second connecting ear 22 can be inserted into the mounting hole, with one end of the second connecting ear 22 and the mounting hole being surface-connected. One end of the second connecting ear 22 is inserted into the mounting hole of the second end 212b of the first shaft portion 212 in the first connecting ear 21, achieving synchronous rotational connection between the first connecting ear 21 and the second connecting ear 22.

[0126] In order to provide a certain damping force when the lug assembly 20 rotates relative to the case 10, in some embodiments, referring to Figures 4 to 6, 8 and 9, the first shaft portion 212 is fitted with an elastic ring 30, which is sandwiched between the inner wall of the fixing hole 111 and the first shaft portion 212.

[0127] The elastic ring 30 is a ring structure made of an elastic compressible material. The material of the elastic ring 30 can be silicone, fluororubber, nitrile rubber, etc. The shape of the elastic ring 30 can be O-shaped, D-shaped, etc. During assembly, the first shaft portion 212 with the elastic ring 30 is inserted into the fixing hole 111 of the mounting portion 11, so that the elastic ring 30 is clamped between the inner wall of the fixing hole 111 and the first shaft portion 212.

[0128] When the lug assembly 20 rotates relative to the case 10, the elastic ring 30 will be compressed and deformed. There is a certain friction between the elastic ring 30 and the inner wall of the fixing hole 111, and between the elastic ring 30 and the first shaft 212. The rotation of the lug assembly 20 has a certain damping force, which realizes the smooth and stable rotation of the lug assembly 20. This avoids the unpleasant noise and shaking caused by the gap between the first shaft 212 and the inner wall of the fixing hole 111, reduces the wear caused by long-term contact between the first shaft 212 and the inner wall of the fixing hole 111, and improves the user experience and reliability.

[0129] To ensure that the elastic ring 30 remains on the first shaft portion 212, in some embodiments, referring to Figures 4 and 8, the first shaft portion 212 has a positioning groove 2122, and the elastic ring 30 is disposed in the positioning groove 2122. By placing the elastic ring 30 in the positioning groove 2122, the elastic ring 30 is held in the first shaft portion 212 and is less likely to detach. After repeated rotations of the lug assembly 20, the elastic ring 30 also remains in the first shaft portion 212, improving the reliability of the assembly structure. The positioning groove 2122 can be an annular groove provided in the first shaft portion 212.

[0130] For example, the first shaft portion 212 has two positioning grooves 2122 arranged at intervals, and each positioning groove 2122 is provided with an elastic ring 30. The two elastic rings 30 are clamped between the inner wall of the first shaft portion 212 and the fixing hole 111, so that the lug assembly 20 can be stably rotated relative to the mounting portion 11.

[0131] In some embodiments, referring to Figures 4 to 6, the damping feel of the lug assembly 20 during rotation can be adjusted by changing the number or interference fit of the elastic rings 30 to meet the needs of the product and the user. The more elastic rings 30 there are, the greater the damping force. The interference fit can be changed by altering the diameter of the fixing hole 111 of the mounting portion 11, the diameter of the positioning groove 2122 of the first shaft portion 212, and the wire diameter of the elastic rings 30. Furthermore, lubricating oil can be applied between the first shaft portion 212 and the inner wall of the fixing hole 111; changing the amount of oil applied can adjust the damping feel of rotating the lug assembly 20.

[0132] To limit the rotation range of the lug assembly 20, in some embodiments, referring to (a) to (c) of Figures 5 and 10, a rotation limiting structure 40 is provided between the wall of the fixing hole 111 and the lug assembly 20 to limit the rotation range of the lug assembly 20 relative to the mounting portion 11. When the lug assembly 20 rotates to a predetermined position, the rotation limiting structure 40 limits the position of the lug assembly 20 and prevents it from rotating further, thereby limiting the range of rotatable angles of the lug assembly 20. By limiting the rotation range of the lug assembly 20, it is easier for the connecting structure 201 (such as spring bar) of the strap 200 to be inserted into the first connecting hole 211 and the second connecting hole 221. It also prevents the lug assembly 20 from rotating and hitting the front 10a or back 10b of the watch case 10 in a drop environment, thus avoiding impact damage to the bezel or the back case.

[0133] In some embodiments, referring to Figures 10(a) to (c), the lug assembly 20 has a first limit position and a second limit position, and the lug assembly 20 is rotatable between the first limit position and the second limit position. When the lug assembly 20 is in the first limit position, as shown in Figure 10(a), the lug assembly 20 is parallel to the front face 10a of the watch case 10, or the lug assembly 20 forms a 90° angle or other value with the front face 10a of the watch case 10. When the lug assembly 20 is in the second limit position, as shown in Figure 10(c), the lug assembly 20 forms a 90° angle or other value with the back face 10b of the watch case 10. The first and second limit positions of the lug assembly 20 can be set as needed.

[0134] For example, referring to (a) to (c) of Figure 10, the lug assembly 20 can rotate relative to the case 10 within an angle range of 0° to 90°, which has a large range of motion and can be adapted to people with different wrist sizes, providing good wearing comfort.

[0135] As shown in Figure 10(a), when the lug assembly 20 is at 0° relative to the case 10, the lug assembly 20 and the back face 10b of the case 10 are parallel. As shown in Figure 10(c), when the lug assembly 20 is at 90° relative to the case 10, the lug assembly 20 and the back face 10b of the case 10 are perpendicular.

[0136] For example, the lug assembly 20 is rotated to a position parallel to the front 10a of the watch case 10 to prevent the lug assembly 20 from rotating freely. Referring to Figure 3, this facilitates the assembly of the connecting structure 201 of the watch strap 200 into the first connecting hole 211 and the second connecting hole 221 of the lug assembly 20.

[0137] In some embodiments, referring to Figures 5 and 10(a) to (c), the rotation limiting structure 40 includes an arcuate groove 41 and a limiting portion 42. One of the arcuate groove 41 and the limiting portion 42 is disposed on the wall surface of the fixing hole 111, and the other is disposed on the first shaft portion 212 or the second connecting ear 22 in the first connecting ear 21. The limiting portion 42 can slide within the arcuate groove 41. By the cooperation of the arcuate groove 41 and the limiting portion 42, the rotation range of the lug assembly 20 can be limited.

[0138] The limiting part 42 can be configured as an arc-shaped segment. The arc-shaped groove 41 has two first mating surfaces 41a distributed opposite each other in the circumferential direction. The limiting part 42 has two first mating surfaces 41a distributed opposite each other in the circumferential direction. The two second mating surfaces 42a of the limiting part 42 are located between the two first mating surfaces 41a of the arc-shaped groove 41. The two second mating surfaces 42a of the limiting part 42 and the two first mating surfaces 41a of the arc-shaped groove 41 correspond one-to-one.

[0139] Referring to Figure 10(a), when one of the second mating surfaces 42a of the limiting part 42 abuts against the first mating surface 41a of the arc groove 41, the lug assembly 20 is limited to the first limit position.

[0140] Referring to Figure 10(c), when the other second mating surface 42a of the limiting part 42 abuts against the first mating surface 41a of the arc groove 41, the lug assembly 20 is limited to the second limit position.

[0141] Referring to Figure 10(b), neither of the two second mating surfaces 42a of the limiting part 42 abuts against the first mating surface 41a of the arc groove 41, and the lug assembly 20 is located between the first limit position and the second limit position.

[0142] By setting the positions of the two first mating surfaces 41a of the arc groove 41 and the distance between the two second mating surfaces 42a of the limiting part 42, the first limit position and the second limit position of the lug assembly 20 can be determined.

[0143] For example, referring to FIG5, the limiting part 42 is disposed on the first shaft part 212 near the first connecting part 213, and the arc groove 41 is disposed on the wall of the fixing hole 111, and the limiting part 42 can slide in the arc groove 41.

[0144] For example, the limiting part 42 is provided on the wall of the fixing hole 111, and the arc groove 41 is provided on the first shaft part 212 near the first connecting part 213, and the limiting part 42 can slide in the arc groove 41.

[0145] For example, the limiting part 42 is provided in the second connecting ear 22, and the arc-shaped groove 41 is provided in the second end 212b of the first shaft part 212, and the limiting part 42 can slide in the arc-shaped groove 41.

[0146] For example, the limiting part 42 is provided at the second end 212b of the first shaft part 212, and the arc-shaped groove 41 is provided in the second connecting ear 22, so that the limiting part 42 can slide in the arc-shaped groove 41.

[0147] To facilitate the insertion of the connecting structure 201 of the watch strap 200 into the first connecting hole 211, in some embodiments, referring to FIG11, the outer surface of the first connecting part 213 has a first guide groove 2131, which is connected to the first connecting hole 211. During assembly, the connecting structure 201 (such as a spring bar) of the watch strap 200 is guided by the first guide groove 2131 and can smoothly slide into the first connecting hole 211, achieving quick installation and reducing the difficulty of assembling the watch strap 200.

[0148] To facilitate the insertion of the connecting structure 201 of the watch strap 200 into the second connecting hole 221, in some embodiments, referring to Figures 5 and 11, the outer surface of the second connecting lug 22 has a second guide groove 2232, which is connected to the second connecting hole 221. During assembly, the connecting structure 201 of the watch strap 200 (such as a spring bar) can be smoothly slid into the second connecting hole 221 guided by the second guide groove 2232, achieving quick installation and reducing the difficulty of assembling the watch strap 200.

[0149] In some embodiments, referring to FIG11, when the plane of the lug assembly 20 is parallel to the front 10a of the watch case 10, the first guide groove 2131 may be located on the side of the first connecting portion 213 facing away from the front 10a of the watch case 10, and the second guide groove 2232 may be located on the side of the second connecting portion 223 facing away from the front 10a of the watch case 10. Referring to FIG2, when the user wears the wearable device 1000, the first guide groove 2131 and the second guide groove 2232 are not visible, giving the wearable device 1000 a better aesthetic appeal.

[0150] In some embodiments, referring to Figures 4 and 8, the mounting portion 11 is cylindrical and has two opposing end faces. The first connecting lug 21 has a first limiting surface 214, which faces one end face of the mounting portion 11. When the first connecting lug 21 is assembled on the watch case 10, the first limiting surface 214 abuts against one end face of the mounting portion 11 to define the relative position of the first connecting lug 21 and the mounting portion 11.

[0151] The second connecting ear 22 has a second limiting surface 224, which faces one end face of the mounting portion 11. When the second connecting ear 22 is assembled on the watch case 10, the second limiting surface 224 abuts against one end face of the mounting portion 11 to limit the relative position of the second connecting ear 22 and the mounting portion 11.

[0152] In some embodiments, referring to Figures 12 to 15, the first connecting ear 21 and the second connecting ear 22 adopt a two-segment symmetrical assembly structure. The first connecting ear 21 includes a first shaft portion 212 and a first connecting portion 213. The first shaft portion 212 has a first end 212a and a second end 212b opposite to each other. The first connecting portion 213 is connected to the first end 212a. The first shaft portion 212 is at least partially located in the fixing hole 111 and can rotate about the axis A1 of the fixing hole 111. The second connecting ear 22 includes a second shaft portion 222 and a second connecting portion 223. The second shaft portion 222 has a third end 222a and a fourth end 222b opposite to each other. The second connecting portion 223 is connected to the third end 222a. The second shaft portion 222 is at least partially located inside the fixing hole 111. The fourth end 222b and the second end 212b are both located inside the fixing hole 111 and are connected to each other. The first connecting portion 213 and the second connecting portion 223 are both located outside the fixing hole 111. The second connecting hole 221 is located in the second connecting portion 223.

[0153] The first shaft portion 212 and the first connecting portion 213 in the first connecting ear 21 may be an integral structure. The second shaft portion 222 and the second connecting portion 223 in the second connecting ear 22 may be an integral structure.

[0154] Both the integrated first connecting ear 21 and the integrated second connecting ear 22 have high strength, are not easily damaged, and are reliable and durable. During assembly, the first shaft portion 212 and the second shaft portion 222 are inserted into the two ends of the fixing hole 111 of the mounting portion 11, so that the second end 212b of the first shaft portion 212 and the fourth end 222b of the second shaft portion 222 are fixedly connected. The number of assembly connection points is small, the assembly is convenient and quick, the machining and assembly tolerances are small, and the amount of wobble when the lug assembly 20 rotates is small.

[0155] In some embodiments, referring to Figures 14 and 15, the second end 212b of the first shaft portion 212 and the fourth end 222b of the second shaft portion 222 can be connected by fasteners (such as screws), riveting, bonding, welding, or tight fitting. These methods enable a reliable connection between the first connecting lug 21 and the second connecting lug 22.

[0156] To facilitate the connection between the first shaft portion 212 and the second shaft portion 222, in some embodiments, referring to FIG13, the mounting portion 11 has a mounting port 112 communicating with the fixing hole 111. The mounting port 112 corresponds to the position where the first shaft portion 212 and the second shaft portion 222 are connected. This allows for the use of fasteners (such as screws), riveting, bonding, welding, or other methods to operate at the mounting port 112 to achieve the connection between the first shaft portion 212 and the second shaft portion 222.

[0157] In some embodiments, referring to Figures 16 and 17, the first connecting ear 21 and the second connecting ear 22 adopt a three-section assembly structure. The first shaft portion 212 and the first connecting portion 213 of the first connecting ear 21 are assembly structures, as are the first shaft portion 212 and the second connecting ear 22. The first shaft portion 212 passes through the fixing hole 111, while the first connecting portion 213 and the second connecting ear 22 are both located outside the fixing hole 111. The three-section structure enables the rotational connection of the lug assembly 20 relative to the mounting portion 11. During assembly, the first shaft portion 212 is inserted into the fixing hole 111 of the mounting portion 11, and both ends of the first shaft portion 212 are connected to the first connecting portion 213 and the second connecting ear 22, respectively.

[0158] The watch body 100, watch lug assembly 20, and wearable device 1000 provided in this application embodiment are not limited to applications in watches; for example, they can be used for connecting the body and strap of other electronic devices.

[0159] Finally, it should be noted that the above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
