Description

Technical Field

[0001] This application relates to the field of terminal technology, specifically to a wearable device. Background Technology

[0002] Reference Figure 1 Wearable devices such as smart rings 100 typically include a functional component 10, a first flexible band 20, and a second flexible band 30. One end of the functional component 10 is connected to the first flexible band 20, and the other end is connected to the second flexible band 30. The first flexible band 20 has multiple spaced adjustment holes 21, and the second flexible band 30 has fasteners 31 configured to be fixed within different adjustment holes 21 to adjust the wearing size of the wearable device. However, providing adjustment holes 21 on the first flexible band 20 occupies space in the functional component 10, affecting the expandability of the wearable device. Utility Model Content

[0003] This application provides a wearable device designed to improve its scalability.

[0004] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0005] This application provides a wearable device for wearing on a limb. The wearable device includes an elastic element, a functional module, and an adjustment mechanism. The elastic element encloses a wearing space and has a first end and a second end with a gap between them. The functional module is disposed on the elastic element. One end of the adjustment mechanism is connected to the first end, and the other end is connected to the second end. The adjustment mechanism is used to adjust the distance between the first end and the second end.

[0006] The wearable device provided in this application comprises an elastic element that encloses a wearable space. A gap exists between the first and second ends of the elastic element. One end of an adjustment mechanism is connected to the first end of the elastic element, and the other end is connected to the second end. The adjustment mechanism is used to adjust the distance between the first and second ends of the elastic element. During the adjustment process, the elastic element itself undergoes elastic deformation to reduce or increase the size of the wearable space, rather than the adjustment mechanism adjusting its own size to achieve this. In the circumferential direction of the wearable device, the proportion occupied by the adjustment mechanism is reduced, while the proportion occupied by the elastic element containing functional modules is increased. This allows for an increase in the number of functional modules in the wearable device, thereby improving its expandability.

[0007] In some embodiments, the adjustment mechanism includes a locking tooth and an adjustment cover. The locking tooth is disposed at a first end and is located outside the elastic member. One end of the adjustment cover covers the first end, and the other end of the adjustment cover is connected to a second end. Along the circumferential direction of the wearable device, a plurality of slots are provided at intervals on the side of the adjustment cover near the elastic member, and the locking tooth is engaged in one of the plurality of slots.

[0008] With the above settings, the distance between the first and second ends of the elastic element can be adjusted by locking the teeth into different slots.

[0009] In some embodiments, the card slot includes a first slot wall and a second slot wall disposed opposite to each other in the circumferential direction of the wearable device. The first slot wall is close to a first end, and the second slot wall is close to a second end. The second slot wall has a third end and a fourth end. The third end is close to the bottom of the card slot, and the fourth end is close to the opening of the card slot. The fourth end is closer to the second end than the third end.

[0010] With the above configuration, in two adjacent slots, as the card tooth moves from the slot relatively closer to the first end to the slot relatively closer to the second end, the inclined second slot wall facilitates the transfer of the card tooth between multiple slots, which facilitates actively reducing the size of the wearing space.

[0011] In some embodiments, the first end is provided with a connecting groove, the opening of the connecting groove facing the outside of the elastic member; the adjustment mechanism also includes a spring, the spring is disposed in the connecting groove, one end of the spring is connected to the locking tooth, and the other end abuts against the bottom wall of the connecting groove, the spring is used to provide elastic force to the locking tooth away from the connecting groove.

[0012] With the above configuration, since the spring always provides elastic force to the tooth away from the connecting groove, as the tooth moves from the groove relatively close to the first end to the groove relatively close to the second end, the tooth slides along the second groove wall of a groove, gradually compressing the spring and reducing the volume of the tooth located outside the elastic element; when the tooth moves to another groove, the elastic force of the spring pushes the tooth into another groove, realizing the transfer of the tooth between two adjacent grooves. The spring further facilitates the transfer of the tooth between multiple grooves, making it easier to actively reduce the size of the wearing space.

[0013] In some embodiments, the adjustment mechanism further includes a connecting seat and a reset key. The connecting seat is disposed in the connecting groove, and the locking teeth and the reset key are both disposed on the side of the connecting seat away from the connecting groove. A spring is located between the connecting seat and the bottom wall of the connecting groove, and the spring provides elastic force to the connecting seat away from the connecting groove. A sliding groove is provided on the adjustment cover, which extends along the circumferential direction of the elastic element and passes through the connecting groove in the extension and contraction direction of the spring. The reset key is located in the sliding groove.

[0014] With the above configuration, both the reset button and the locking teeth are located on the connector. During the process of the locking teeth moving between multiple slots and reducing the size of the wearable space, the reset button moves along with the locking teeth. The sliding groove provides space for the reset button to move. When the size of the wearable space needs to be increased, pressure is applied to the reset button, which compresses the spring and drives the locking teeth away from the slots. The elastic element returns to its shape, causing the locking teeth to move relative to the slot closest to the first end, thereby increasing the size of the wearable space.

[0015] In some embodiments, the adjusting cover includes a top plate and a side plate connected together, the top plate covering the outer wall of the first end, and the side plate covering the side wall of the first end; a slot and a sliding groove are provided on the top plate; the inner wall of the side plate is provided with a first limiting structure, and the side wall of the first end is provided with a second limiting structure, the first limiting structure and the second limiting structure are connected in cooperation, and the relative movement trajectory of the first limiting structure and the second limiting structure is arc-shaped.

[0016] With the above settings, since the first limiting structure moves in an arc shape relative to the second limiting structure, the first limiting structure can drive the adjustment cover to always fit with the elastic element during the movement, so that the wearable device is always in a circular shape, ensuring the roundness of the wearable device.

[0017] In some embodiments, the plurality of slots includes a first slot, a second slot, and at least one third slot, the third slot being located between the first slot and the second slot; the pawl is engaged in the first slot, the elastic element and the adjusting mechanism forming a maximum circular ring; the pawl is engaged in the second slot, the elastic element and the adjusting mechanism forming a minimum circular ring; the curvature of the arc is greater than or equal to the curvature of the maximum circular ring and less than or equal to the curvature of the minimum circular ring.

[0018] With the above settings, when the locking teeth are engaged in the first slot, the wearable device forms the largest circle in the circumferential direction; when the locking teeth are engaged in the second slot, the wearable device forms the smallest circle in the circumferential direction, thereby ensuring the roundness of the wearable device.

[0019] In some embodiments, the first limiting structure includes a limiting groove, and the second limiting structure includes a limiting pin; or, the first limiting structure includes a limiting pin, and the second limiting structure includes a limiting groove; the limiting pin is located in the limiting groove, and the extending direction of the limiting groove is arc-shaped.

[0020] With the above settings, the limiting pin is located in the limiting groove, and the limiting pin moves in the limiting groove. The extension direction of the limiting groove is arc-shaped, so that the movement trajectory of the limiting pin in the limiting groove is arc-shaped, thereby ensuring the roundness of the wearable device.

[0021] In some embodiments, the inner wall of the side plate is provided with a third limiting structure, and the side wall at the first end is provided with a fourth limiting structure. The third limiting structure and the fourth limiting structure are connected in cooperation, wherein the first limiting structure and the third limiting structure are spaced apart, and the second limiting structure and the fourth limiting structure are spaced apart.

[0022] With the above settings, the first and second limiting structures are used to limit the relative positions of the adjustment mechanism and the elastic element, and the third and fourth limiting structures are also used to limit the relative positions of the adjustment mechanism and the elastic element, which can further ensure the roundness of the wearable device.

[0023] In some embodiments, the third limiting structure includes a limiting rib, and the fourth limiting structure includes a limiting groove, with the limiting rib located within the limiting groove.

[0024] In some embodiments, the adjustment mechanism and the second end are an integral structure.

[0025] The above-mentioned design, which integrates the adjustment mechanism and elastic elements into a single structure, reduces the complexity of wearable devices.

[0026] In some embodiments, the adjusting mechanism is rotatably connected to the second end.

[0027] With the above settings, during the process of adjusting the size of the wearable space, the adjustment mechanism can rotate relative to the second end, so that the wearable device always approaches or forms a circular shape, thereby improving the appearance and refinement of the wearable device.

[0028] In some embodiments, the elastic element includes a metal element.

[0029] The above settings make the elastic component less prone to plastic deformation, thus improving the service life of wearable devices.

[0030] In some embodiments, the wearable device further includes a contact located inside the elastic member, the contact comprising a flexible material, to improve the comfort of the user wearing the device. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0046] It should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection or an integral connection; they can also refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0047] Reference Figure 2This application provides a wearable device 200, which may include a smart ring, a smart bracelet, etc. The wearable device 200 is worn on a user's limbs. For example, in an embodiment where the wearable device 200 is a smart ring, the smart ring is worn on the user's finger; in an embodiment where the wearable device 200 is a smart bracelet, the smart bracelet is worn on the user's wrist. Both smart rings and smart bracelets can be used to monitor a user's physiological parameters such as heart rate, blood oxygen, and body temperature. They can also upload the collected information to the user's electronic devices (mobile phones, tablets, personal computers, etc.) via wireless transmission methods such as Bluetooth, allowing users to experience a smart digital life.

[0048] Among them, reference Figure 2 and Figure 3 The wearable device 200 includes an elastic element 210 and an adjustment mechanism 220. The elastic element 210 is a non-closed ring, enclosing a wearable space 201. The elastic element 210 has a first end 211 and a second end 212, with a gap between them. This gap can be understood as a notch in the non-closed ring. One end of the adjustment mechanism 220 is connected to the first end 211 of the elastic element 210, and the other end is connected to the second end 212. The elastic element 210 and the adjustment mechanism 220 form a closed ring structure. The adjustment mechanism 220 is used to adjust the distance between the first end 211 and the second end 212 of the elastic element 210 to either reduce or increase the size of the wearable space 201.

[0049] In the above embodiments, the elastic element 210 includes a metal element. The metal used to make the elastic element 210 may include a high elastic alloy with low elastic modulus and high yield strength, such as titanium alloy, zirconium-based alloy, stainless steel, etc. Through the above arrangement, the elastic element 210 is not prone to plastic deformation, thereby improving the service life of the wearable device 200.

[0050] When the elastic element 210 is in its normal state, i.e., when it is not subjected to any external force, the wearing space formed by the elastic element 210 and the adjusting mechanism 220 is at its maximum. During the process of the adjusting mechanism 220 reducing the distance between the first end 211 and the second end 212 of the elastic element 210, the first end 211 and the second end 212 of the elastic element 210 move closer together, causing the elastic element 210 to deform along the circumferential direction. The curvature of the elastic element 210 in the circumferential direction increases, and the wearing space formed by the elastic element 210 and the adjusting mechanism 220 decreases. At this time, the elastic element 210 possesses elastic potential energy that causes the first end 211 and the second end 212 to move away from each other. When the adjusting mechanism 220 releases the restriction on the first end 211 and the second end of the elastic element 210, the elastic potential energy stored in the elastic element 210 causes the first end 211 and the second end 212 to move away from each other, the curvature of the elastic element 210 in the circumferential direction decreases, and the wearing space formed by the elastic element 210 and the adjusting mechanism 220 increases.

[0051] The wearable device 200 also includes at least one functional module 230, which is disposed on the elastic element 210. In this embodiment, the multiple functional modules 230 may include a PPG (Photoplethysmography) measurement module, an MCU (Microcontroller Unit) module, a touch module 231, an NFC (Near Field Communication) module, and a Bluetooth module, etc. Among the multiple different functional modules 230, the functional modules 230 are disposed on the inner or outer side of the elastic element 210 based on their different functions. For example, if the PPG measurement module is used to monitor physiological parameters such as heart rate and blood oxygen, then the PPG measurement module is disposed on the inner side of the elastic element 210; if the NFC module is used to realize near field communication, then the NFC module is disposed on the outer side of the elastic element 210; the Bluetooth module can realize the communication connection between the wearable device 200 and electronic devices (mobile phones, tablets, personal computers, etc.), and is used to transmit physiological parameters, control signals, touch signals, communication signals, etc. collected by other functional modules to electronic devices, realizing interconnection between various devices and enabling users to experience a smart digital life.

[0052] In some embodiments, the wearable device 200 further includes a contact 280 located inside the elastic member 210. The contact 280 comprises a flexible material, such as imitation leather or silicone, to improve the comfort of the user wearing the device 200. In embodiments where the functional module 230 includes a PPG measurement module, the PPG measurement module is disposed between the elastic member 210 and the contact 280. This allows the PPG measurement module to be close to the user's limb surface, improving the efficiency and accuracy of PPG measurement.

[0053] The wearable device 200 provided in this application has an elastic element 210 enclosing a wearable space 201. A gap exists between the first end 211 and the second end 212 of the elastic element 210. One end of an adjustment mechanism 220 is connected to the first end 211 of the elastic element 210, and the other end of the adjustment mechanism 220 is connected to the second end 212 of the elastic element 210. The adjustment mechanism 220 is used to adjust the distance between the first end 211 and the second end 212 of the elastic element 210. During the process of adjusting the distance between the first end 211 and the second end 212, the elastic element 210 itself undergoes elastic deformation to reduce or increase the size of the wearable space 201, rather than the adjustment mechanism 220 adjusting its own size to achieve this. In the circumferential direction of the wearable device 200, the proportion occupied by the adjustment mechanism 220 is reduced, while the proportion occupied by the elastic element 210, which is equipped with functional modules 230, is increased. This increases the number of functional modules 230 in the wearable device 200, thereby improving the expandability of the wearable device 200.

[0054] In some embodiments, refer to Figure 3 and Figure 4 The adjustment mechanism 220 includes a locking tooth 221 and an adjustment cover 222. The locking tooth 221 is disposed at the first end 211 of the elastic member 210 and is located on the outside of the elastic member 210. One end of the adjustment cover 222 covers the outside of the first end 211, and the other end of the adjustment cover 222 is connected to the second end 212. Along the circumferential direction of the wearable device 200, a plurality of slots 2220 are provided at intervals on the side of the adjustment cover 222 near the elastic member 210, and the locking tooth 221 is engaged in one of the plurality of slots 2220. With the above arrangement, the distance between the first end 211 and the second end 212 of the elastic member 210 can be adjusted by the locking tooth 221 being engaged in different slots 2220.

[0055] In the above embodiments, the cross-section of the elastic element 210 can be approximated as a rectangle, and the elastic element 210 can be approximated as a circular cylinder; the circular cylinder has a large circular side surface, a small circular side surface, and a circular surface, wherein the large circular side surface and the small circular side surface are connected by the circular surface. In some embodiments, the locking teeth 221 can be located on the large circular side surface of the elastic element 210, and correspondingly, multiple locking slots 2220 are provided on the surface of the adjusting cover 222 facing the large circular side surface. In other embodiments, the locking teeth 221 can be located on the circular surface of the elastic element 210, and correspondingly, multiple locking slots 2220 are provided on the surface of the adjusting cover 222 facing the circular surface. In both of the above embodiments, the multiple locking slots 2220 are spaced apart along the circumferential direction, and each locking slot 2220 is used to engage with the locking teeth 221. The locking teeth 221 engaging in different locking slots 2220 can respectively correspond to different distances between the first end 211 and the second end 212 of the elastic element 210.

[0056] In the above embodiments, referring to Figure 4 The adjustment cover 222 has multiple slots 2220, including a first slot 2201, a second slot 2202, and at least one third slot 2203. The first slot 2201 is located near the first end 211 of the elastic member 210, the second slot 2202 is located near the second end 212 of the elastic member 210, and the third slot 2203 is located between the first slot 2201 and the second slot 2202. The locking teeth 221 can be independently engaged in the first slot 2201, the second slot 2202, or the third slot 2203. In the embodiment where the locking teeth 221 are engaged in the first slot 2201, the wearing space 201 formed by the elastic member 210 and the adjustment mechanism 220 is the largest, forming a maximum annular shape in the circumferential direction. In the embodiment where the locking teeth 221 are engaged in the second slot 2202, the wearing space 201 formed by the elastic member 210 and the adjustment mechanism 220 is the smallest, forming a minimum annular shape in the circumferential direction.

[0057] In some embodiments, refer to Figure 2 and Figure 5 The card slot 2220 includes a first slot wall 2221 and a second slot wall 2222 disposed opposite to each other along the circumferential direction of the wearable device. The first slot wall 2221 is close to the first end 211, and the second slot wall 2222 is close to the second end 212. The second slot wall 2222 has a third end 2223 and a fourth end 2224. The third end 2223 is close to the bottom of the card slot 2220, and the fourth end 2224 is close to the opening of the card slot 2220. The fourth end 2224 is closer to the second end 212 than the third end 2223, causing the second slot wall 2222 to be inclined toward the second end 212. With the above arrangement, in two adjacent card slots 2220, during the process of the card tooth 221 moving from the card slot 2220 relatively close to the first end 211 to the card slot 2220 relatively close to the second end 212, the inclined second slot wall 2222 facilitates the transfer of the card tooth 221 between multiple card slots 2220, which facilitates the active reduction of the size of the wearable space 201.

[0058] In the above embodiments, the first groove wall 2221 can be vertically or inclined. For example, the first groove wall 2221 has a fifth end 2225 and a sixth end 2226, wherein the fifth end 2225 is near the bottom of the slot 2220, and the sixth end 2226 is near the opening of the slot 2220; the sixth end 2226 is closer to the first end 211 than the fifth end 2225, causing the first groove wall 2221 to tilt towards the first end 211. The tilt angle of the first groove wall 2221 is greater than or equal to 0 and less than the tilt angle of the second groove wall 2222. It can be understood that when the tilt angle of the first groove wall 2221 is equal to 0, it can be considered that the first groove wall 2221 is vertically arranged. Through this arrangement, in two adjacent slots 2220, the card teeth 221 are prevented from actively transferring from the slot 2220 relatively closer to the second end 212 to the slot 2220 relatively closer to the first end 211, thus avoiding actively expanding the size of the wearing space 201.

[0059] In the above embodiments, referring to Figure 6 and Figure 7 The first end 211 is provided with a connecting groove 213. The adjusting mechanism 220 also includes a spring 223, which is disposed in the connecting groove 213. One end of the spring 223 is connected to the retaining tooth 221, and the other end abuts against the bottom wall of the connecting groove 213. The spring 223 is used to provide a spring force to the retaining tooth 221 away from the connecting groove 213. The retaining tooth 221 passes through the opening of the connecting groove 213, and some of the retaining teeth 221 are located on the outside of the elastic member 210. In the embodiment where the retaining tooth 221 is located on the large circular side of the elastic member 210, multiple retaining grooves 2220 are disposed on the surface of the adjusting cover 222 facing the large circular side, and the spring 223 always provides a spring force to the retaining tooth 221 perpendicular to the large circular side outward. In the embodiment where the retaining tooth 221 can be located on the annular surface of the elastic member 210, multiple retaining grooves 2220 are disposed on the surface of the adjusting cover 222 facing the annular surface, and the spring 223 always provides a spring force to the retaining tooth 221 perpendicular to the annular surface outward.

[0060] With the above configuration, since the spring 223 always provides elastic force to the tooth 221 away from the connecting groove 213, as the tooth 221 moves from the groove 2220 relatively close to the first end 211 to the groove 2220 relatively close to the second end 212, the tooth 221 slides along the second groove wall 2222 of the groove 2220, gradually compressing the spring 223 and reducing the volume of the tooth 221 located outside the elastic member 210; when the tooth 221 moves to another groove 2220, the elastic force of the spring 223 pushes the tooth 221 into another groove 2220, realizing the transfer of the tooth 221 between two adjacent grooves 2220. The spring 223 further facilitates the transfer of the tooth 221 between multiple grooves 2220, which facilitates actively reducing the size of the wearing space 201.

[0061] In some embodiments, refer to Figure 6 , Figure 7 and Figure 8 The adjustment mechanism 220 also includes a connecting seat 224 and a reset button 225. The connecting seat 224 is disposed within the connecting groove 213, and both the locking teeth 221 and the reset button 225 are disposed on the side of the connecting seat 224 away from the connecting groove 213. Similar to the locking teeth 221, the reset button 225 also passes through the opening of the connecting groove 213, and part of the reset button 225 is also located on the outside of the elastic member 210. The aforementioned spring 223 is located between the connecting seat 224 and the bottom wall of the connecting groove 213, and the spring 223 provides elastic force to the connecting seat 224 away from the connecting groove 213. Correspondingly, the adjustment cover 222 is provided with a sliding groove 202, which extends along the circumferential direction of the elastic member 210 and passes through the connecting groove 213 in the extension and retraction direction of the spring 223. The reset button 225 is located within the sliding groove 202, and part of the reset button 225 is located on the side of the sliding groove 202 away from the elastic member 210. With the above configuration, both the reset button 225 and the locking teeth 221 are mounted on the connecting seat 224. During the process of the locking teeth 221 moving between multiple slots 2220 and reducing the size of the wearing space 201, the reset button 225 moves along with the locking teeth 221, and the sliding groove 202 provides space for the reset button 225 to move. When the size of the wearing space 201 needs to be increased, pressure is applied to the reset button 225, which compresses the spring 223, causing the locking teeth 221 to leave the slots 2220. The elastic element 210 then returns to its shape, causing the locking teeth 221 to move relative to the slot 2220 (first slot 2201) closest to the first end 211, thereby increasing the size of the wearing space 201. In the above embodiment, the locking teeth 221 and the connecting seat 224 can be an integral structure, and the reset button 225 and the connecting seat 224 can be an integral structure.

[0062] In an embodiment where the locking tooth 221 is located on the large circular side surface of the elastic member 210, a portion of the reset button 225 is also located on the large circular side surface of the elastic member 210; the sliding groove 202 is located on the surface of the adjusting cover 222 facing the large circular side surface. In an embodiment where the locking tooth 221 can be located on the annular surface of the elastic member 210, a portion of the reset button 225 is also located on the annular surface of the elastic member 210, and the sliding groove 202 is located on the surface of the adjusting cover 222 facing the annular surface.

[0063] In some embodiments, refer to Figure 3 and Figure 4 The adjusting cover 222 includes a top plate 240 and a side plate 250 connected together; wherein, the top plate 240 covers the outer wall (large circular side) of the first end 211, and the side plate 250 covers the side wall (annular surface) of the first end 211. The aforementioned slot 2220 and sliding groove 202 can both be provided on the top plate 240 of the adjusting cover 222.

[0064] In the above embodiments, one end of the adjusting mechanism 220 connected to the second end 212 of the elastic member 210 is rotatably connected to the second end 212. Exemplarily, the structure enabling the rotatable connection may include a fixing pin 261 and a fixing groove 262. In some embodiments, the fixing pin 261 is disposed on the side plate 250 of the adjusting cover 222, and the fixing groove 262 is disposed on the side wall of the second end 212, with the fixing pin 261 located within the fixing groove 262, thereby achieving a rotatable connection between the adjusting cover 222 of the adjusting mechanism 220 and the second end 212 of the elastic member 210. In other embodiments, the fixing pin 261 is disposed on the side wall of the second end 212, and the fixing groove 262 is disposed on the side plate 250 of the adjusting cover 222, with the fixing pin 261 located within the fixing groove 262, similarly achieving a rotatable connection between the adjusting cover 222 of the adjusting mechanism 220 and the second end 212 of the elastic member 210. With the above settings, during the process of adjusting the size of the wearable space 201, the adjusting mechanism 220 can rotate relative to the second end 212, so that the wearable device 200 always approaches or is in a circular shape, thereby improving the appearance and refinement of the wearable device 200.

[0065] In the above embodiments, the end of the adjustment mechanism 220 connected to the second end 212 of the elastic member 210 can also be fixedly connected to the second end 212. The adjustment mechanism 220 and the second end 212 are an integral structure. It is understood that the adjustment mechanism 220 can be made of the same material as the elastic member 210, and the adjustment mechanism 220 can also include titanium alloy, zirconium-based alloy, stainless steel, etc. Through the above arrangement, the integral structure of the adjustment mechanism 220 and the elastic member 210 can reduce the complexity of the wearable device 200.

[0066] Reference Figure 2 , Figure 3 as well as Figure 9 In embodiments where the adjusting mechanism 220 is rotatably connected to the elastic element 210 or where the adjusting mechanism 220 and the elastic element 210 are integrally formed, the adjusting mechanism 220 further includes a first limiting structure 271 and a second limiting structure 272. In embodiments where the adjusting cover 222 includes a top plate 240 and a side plate 250, the first limiting structure 271 is disposed on the inner wall of the side plate 250, and the second limiting structure 272 is disposed on the side wall of the first end 211; wherein the inner wall of the side plate 250 is disposed opposite to the side wall of the first end 211, the first limiting structure 271 and the second limiting structure 272 are connected in cooperation, and the relative movement trajectory of the first limiting structure 271 and the second limiting structure 272 is arc-shaped. With the above settings, since the first limiting structure 271 moves in an arc shape relative to the second limiting structure 272, the first limiting structure 271 can drive the adjusting cover 222 to always fit with the elastic element 210 during the movement, so that the wearable device 200 is always in a circular shape, ensuring the roundness of the wearable device 200.

[0067] When the locking teeth 221 are engaged in the first slot 2201, the wearable device 200 forms a maximum circular ring in the circumferential direction. When the locking teeth 221 are engaged in the second slot 2202, the wearable device 200 forms a minimum circular ring in the circumferential direction. In this embodiment, in the arc-shaped trajectory formed by the relative movement of the first limiting structure 271 and the second limiting structure 272, the curvature of the arc is greater than or equal to the curvature of the maximum circular ring and less than or equal to the curvature of the minimum circular ring. Through the above arrangement, when the locking teeth 221 are engaged in the first slot 2201, the wearable device 200 forms a maximum circular ring in the circumferential direction; when the locking teeth 221 are engaged in the second slot 2202, the wearable device 200 forms a minimum circular ring in the circumferential direction, thereby ensuring the true roundness of the wearable device 200.

[0068] In some embodiments of the above examples, the first limiting structure 271 includes a limiting groove, and the second limiting structure 272 includes a limiting pin; that is, the limiting groove is disposed on the inner wall of the side plate 250, and the limiting pin is disposed on the side wall of the first end 211. The limiting pin is located in the limiting groove and moves within the limiting groove; wherein, the extending direction of the limiting groove is arc-shaped, so that the movement trajectory of the limiting pin within the limiting groove is arc-shaped, thereby ensuring the roundness of the wearable device 200.

[0069] In some other embodiments of the above embodiments, the first limiting structure 271 includes a limiting pin, and the second limiting structure 272 includes a limiting groove; that is, the limiting pin is disposed on the inner wall of the side plate 250, the limiting groove is disposed on the side wall of the first end 211, the limiting pin is located in the limiting groove, and the limiting pin moves in the limiting groove; similarly, the extension direction of the limiting groove is arc-shaped, so that the movement trajectory of the limiting pin in the limiting groove is arc-shaped, thereby ensuring the roundness of the wearable device 200.

[0070] In embodiments where the adjusting mechanism 220 is rotatably connected to the elastic member 210 or where the adjusting mechanism 220 and the elastic member 210 are integrally formed, the adjusting mechanism 220 further includes a third limiting structure 273 and a fourth limiting structure 274. In embodiments where the adjusting cover 222 includes a top plate 240 and a side plate 250, the third limiting structure 273 is disposed on the inner wall of the side plate 250, and the fourth limiting structure 274 is disposed on the side wall of the first end 211; wherein the inner wall of the side plate 250 is disposed opposite to the side wall of the first end 211, and the third limiting structure 273 and the fourth limiting structure 274 are connected in cooperation; wherein the third limiting structure 273 and the first limiting structure 271 are spaced apart, and the second limiting structure 272 and the fourth limiting structure 274 are spaced apart. With the above settings, the first limiting structure 271 and the second limiting structure 272 are used to limit the relative position of the adjustment mechanism 220 and the elastic member 210, and the third limiting structure 273 and the fourth limiting structure 274 are also used to limit the relative position of the adjustment mechanism 220 and the elastic member 210, which can further ensure the roundness of the wearable device 200.

[0071] In the above embodiment, the third limiting structure 273 includes a limiting rib, and the fourth limiting structure 274 includes a limiting groove. The limiting rib is located in the limiting groove and can slide relative to the limiting groove.
