[0017] In an embodiment of the present invention, each of the first deformation units includes at least one torsion spring and at least four first rotating arms;

[0018] All of the first rotating arms are rotatably connected end to end to form a polygonal ring structure;

[0019] Each of the torsion springs is connected to two of the first rotating arms that are close to the outer ring and rotatably connected, and applies a force that causes the two first rotating arms to approach each other;

[0020] A connection portion of two of the first rotating arms that are close to the outer ring and rotatably connected forms one of the first connecting portions, and a connection portion of two of the first rotating arms that are close to the restraint portion and rotatably connected forms one of the second connecting portions.

[0021] In an embodiment of the present invention, the deformation assembly further has a plurality of second deformation units located in the active space, and the first deformation units and the second deformation units are alternately arranged and connected in sequence; the second deformation units include at least four second rotating arms;

[0026] In an embodiment of the present invention, the sealing section has a foldable part, and a deformation gap is formed between the foldable part and at least one of the inner side walls of the outer ring.

By designing the relevant structures for realizing the elastic connection between the binding parts and the outer ring, the tightening force can be adjusted to a range suitable for human wearing; or a customized elastic connection structure can be made according to the customer's requirements for wearing reliability to meet the requirements of different users for the tightening force applied to the inner ring in terms of wearing reliability. In this way, while ensuring a good wearing experience for the user, the reliable wearing of the wearable device on the user's limb can be realized by means of the inward tightening force of the inner ring.

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0054] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0055] In addition, the descriptions involving "first", "second", etc. in the present invention are for descriptive purposes only, and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel scenarios. Taking "A and / or B" as an example, it includes Scenario A, or Scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0056] Please refer to Figures 1 to 4 , the wearable device provided by the present invention includes an outer ring 11 and an inner ring 12; the inner ring 12 has at least two binding parts 121, and all the binding parts 121 cooperate to form an opening through which a human limb can be worn; each binding part 121 is spaced apart from and elastically connected to the outer ring 11; each binding part 121 can move closer or farther away relative to the outer ring 11 to change the diameter of the opening.

[0057] In the technical solution of the present invention, the wearable device is for human wear. The wearable device includes an outer ring 11 and an inner ring 12. The inner ring 12 has at least two binding parts 121, and all the binding parts 121 cooperate to form an opening through which a human limb can be worn; each binding part 121 is spaced apart from and elastically connected to the outer ring 11. Thus, by initially designing the diameter of the opening formed by enclosing all the binding parts 121 to be the minimum diameter that meets the needs of market users, during the process of the user wearing the wearable device, all the binding parts 121 are squeezed by the user's limb, and thus move farther away relative to the outer ring 11, so that the inner ring 12 can adaptively increase the diameter of the opening corresponding to the different thicknesses of the limbs of different users, forming an adaptive adjustment of the wearing diameter, and expanding the compatibility and application range of the wearable device for different user groups.

[0058] In addition, in the present invention, the binding parts 121 of the inner ring 12 and the outer ring 11 are connected by means of elastic connection. When worn, the binding parts 121 of the inner ring 12 will apply a tightening force to the user's limb. By designing the relevant structures for realizing the elastic connection between the binding parts 121 and the outer ring 11, the tightening force can be adjusted to a range suitable for human wear; alternatively, a customized elastic connection structure can be made according to the customer's requirements for wearing reliability to meet the requirements of different users for the tightening force applied to the inner ring 12 in terms of wearing reliability. Thus, while ensuring a good wearing experience for the user, the reliable wearing of the wearable device on the user's limb can be achieved by means of the inward tightening force of the inner ring 12.

[0059] The elastic connection design between the binding portion 121 and the outer ring 11 also allows the binding portions 121 of the inner ring 12 to return to their original positions when the wearable device is taken off / removed by the user. This provides a structural basis for the reuse of the wearable device: it allows the same user to wear and take off the wearable device multiple times, and allows different family members to share the same wearable device without having to worry about the different limb thicknesses of different members of the same family group. At least it provides a low-cost solution for the inheritance or use of wearable devices as fixed property among different family members.

[0060] It can be understood that the wearable device can be a smart ring worn on the finger, a smart bracelet worn on the wrist, a watch, a foot ring worn on the ankle, and other smart devices. By setting corresponding electronic devices 30 between the inner ring 12 and the outer ring 11 and on the outer ring 11, electronic functions such as health monitoring, identity recognition, and human-computer exchange can be realized.

[0061] The outer ring 11 and the inner ring 12 form the outer shape of the wearable device. The inner ring 12 has at least two binding parts 121. The cross-sectional shapes of the outer ring 11 and the binding part 121 are both in the shape of "匚". Specifically, the outer ring 11 and the binding part 121 each include two folded edges and a supporting edge. The two folded edges are respectively arranged at the two ends of the supporting edge. At the same time, the two folded edges are arranged on the same side of the supporting edge and extend in the same direction. The extending direction is the moving direction of the binding part 121. In this way, the two folded edges of the binding part 121 can be inserted into the outer ring 11. At the same time, the outer ring 11 provides a moving space for the binding part 121, so that each binding part 121 can gather or disperse relative to the outer ring 11 to change the caliber of the through port. It can be understood that the two folded edges of the binding part 121 can abut against the folded edges of the outer ring 11 in the extending direction of the supporting edge; or, the two folded edges of the binding part 121 are arranged at intervals from the folded edges of the outer ring 11 in the extending direction of the supporting edge; this is not limited here.

[0062] In one embodiment, see Figure 5At least one elastic strip 1211 is provided on the side of the supporting edge of each binding portion 121 facing the outer ring 11, and the elastic strip 1211 has a bendable section, which extends from the supporting edge of the binding portion 121 to the supporting edge of the outer ring 11, and each bendable section has a plurality of deformable corner portions, and the outer ring 11 and the binding section are connected by the elastic strip 1211 to form an elastic connection. Taking the smart ring as an example, when the smart ring is worn by the human body, all the binding sections can squeeze the elastic strip 1211 inwardly and move toward the outer ring 11 due to the force from the fingers. When the smart ring moves to the appropriate position of the finger, the binding section is subjected to the force of the elastic strip 1211 and the force of the finger in the same general direction. The binding section is in a static state due to the force balance, and is fixed on the finger to complete the wearing. In this process, the deformation amount of the squeezed shape changes with the size of the finger, so that the smart ring can be adaptively worn in accordance with the size of the finger, thereby improving the scope of application of the smart ring; in another embodiment, please refer to Figure 6 The inner ring 12 has a first binding portion 121 and a second binding portion 121. One end of the first binding portion 121 is rotatably connected with one end of the second binding portion 121 to form a first rotating portion. The other end of the first binding portion 121 and the other end of the second binding portion 121 are spaced apart to form a clearance space 12a. The clearance space 12a has Figure 4As shown by the dotted lines in the figure, a plurality of elastic strips 1211 are provided on one side of the supporting edge of the outer ring 11 facing the first binding portion 121 and the second binding portion 121, a portion of the elastic strips 1211 are located near the position of the make way space 12a, and a portion of the elastic strips 1211 are located near the position of the first rotating portion. In this way, each binding portion 121 can be gathered or dispersed relative to the outer ring 11 to change the diameter of the through-port, thereby improving the application range of the smart ring; in the above two embodiments, because the elastic strip 1211 is in a compressed state when the wearable device is worn, it always has a tendency to recover from deformation. After the wearable device is removed, the elastic strip 1211 is deformed and restored to a natural state, thereby restoring the binding portion 121 to its position, and the diameter of the through-port is at its minimum state. state, so that one wearable device can meet the wearing needs of different users; it can be understood that the outer ring 11 is a closed structure formed by connecting the end to the end, so that in the process of the restraining part 121 gathering or dispersing relative to the outer ring 11, the size of the outer ring 11 will not be deformed, that is, the size of the outer ring 11 remains unchanged, and the diameter of the through-hole changes, thereby ensuring that the maximum outer diameter of the wearable device remains consistent, so that the aesthetics of the wearable device will not change; it can also be understood that the elastic strip 1211 is connected to the outer ring 11 or the restraining part 121 through integral molding, and the specific molding process can be adaptively set according to factors such as the material of the outer ring 11, the restraining part 121 and the elastic strip 1211, the difficulty of processing and other factors, and is not limited here, and it is only necessary to satisfy that the elastic strip 1211 can be fixed on the outer ring 11 or the restraining part 121.

[0063] For further information, see Figure 5 and Figure 7 All the binding parts 121 are arranged at intervals along the circumferential direction of the inner circumferential wall of the outer ring 11, and a clearance space 12a is formed between any two adjacent binding parts 121. Figure 7In the figure, the reference numeral 12a only points to the dotted frame, which indicates the clearance space 12a formed by the interval arrangement of any two adjacent restraining parts 121, wherein each restraining part 121 can be connected to the outer ring 11 through an elastic strip 1211 and an airbag, thereby realizing an elastic connection between the two. It can be understood that each clearance space 12a can provide activity space 10a for the restraining parts 121 on both sides thereof. During the wearing and moving process of the wearable device, the clearance space 12a is gradually compressed, the restraining parts 121 gather together, and the inner diameter of the wearable device gradually increases. When the wearable device is moved to a suitable wearing position, the force exerted by the human body on the inner ring 12 and the force exerted on the inner ring 12 are The thrusts are equal and opposite, thereby completing the wearing of the wearable device. During this process, because the binding parts 121 can move toward or away from the outer ring 11, the inner diameter of the ring can be adjusted steplessly, so that a wearable device can adapt to wearing places of different thicknesses, which can improve the applicability of the wearable device; further, all the binding parts 121 are arranged in the same specification, and at the same time, the two adjacent binding parts 121 are evenly spaced so that all the clearance spaces 12a are spaces of the same size. In this way, it can be ensured that all the binding parts 121 have the same moving distance, thereby ensuring the uniformity of the gathering or dispersion of each binding part 121 relative to the outer ring 11.

[0064] It should be pointed out that the wearable device proposed in the present application has a stepless adjustment mechanism because each binding portion 121 can move toward or away from the outer ring 11 through an elastic connection. For example, when each binding portion 121 moves toward the outer ring 11, they gather together, and the clearance space 12a between each binding portion 121 is continuously compressed, and the diameter of the opening is continuously increased. The binding portion 121 can move toward the outer ring 11 because during the wearing process of the ring, the wearing size is continuously increased, and the wearing size is larger than the size of the ring aperture. The binding portion 121 is subjected to a force from the human body. Under this force, the binding portion 121 is driven to move toward the outer ring 11. At the same time, the binding portion 121 is subjected to a thrust provided by structures such as the elastic strip 1211 and the airbag. When the wearable device is worn to a suitable position, the force exerted by the human body on the binding portion 121 and the thrust exerted on the binding portion 121 by the inside of the ring offset each other. That is, during the wearing process of the wearable device, as long as it is within the deformation range of structures such as the elastic strip 1211 and the airbag, the wearable device can be fixed at any position on the finger.

[0065] In another embodiment of the present invention, see Figure 8The inner ring 12 also has at least two deformation parts 122, each deformation part 122 is located between any two adjacent binding parts 121 and connected to the two binding parts 121. Specifically, the inner ring 12 is a closed structure connected end to end. The inner ring 12 includes a deformation part 122 and a binding part 121. The binding part 121 and the deformation part 122 are arranged alternately and connected in sequence. The deformation part 122 has a deformable segment, which extends along the circumferential direction of the inner circumferential wall of the outer ring 11. Each deformable segment has a plurality of deformation angle parts. The two binding segments are connected by each deformation part 122 so that each binding segment can be gathered or dispersed relative to the outer ring 11 to change the caliber of the through-hole. In this process, the extension direction of the deformation part 122 is the same as that of the binding part 121. The extension direction is consistent, therefore, the deformation forces generated by each deformation portion 122 offset each other in the circumferential direction. It can be understood that the use of the deformation portion 122 can improve the sealing between the outer ring 11 and the inner ring 12. At the same time, the deformation portion 122 also has a heat conduction effect. The heat generated by the electronic device 30 of the wearable device can be transferred to the space between the inner and outer rings 11 through the deformation portion 122, thereby avoiding the problem of structural damage caused by thermal stress concentration; in another embodiment, the inner ring 12 includes four uniform and spaced binding portions 121. For the sake of clarity, the four binding portions 121 are defined herein as a first binding portion 121, a second binding portion 121, a third binding portion 121 and a fourth binding portion 121, please refer to Figure 9 ,exist Figure 9 In the figure, the dotted line pointed to by the label 12a is the clearance space 12a, the first binding part 121 and the second binding part 121 are connected by a deformation part 122, the third binding part 121 and the fourth binding part 121 are connected by a deformation part 122, the first binding part 121 and the fourth binding part 121 are arranged at intervals to form a clearance space 12a, and the second binding part 121 and the third binding part 121 are arranged at intervals to form a clearance space 12a. In this way, while achieving heat conduction, stepless adjustment can also be achieved.

[0066] In one embodiment of the present invention, each binding portion 121 can move closer to or away from the outer ring 11 in the radial direction of the outer ring 11. Specifically, all elastic strips 1211 located between the binding portion 121 and the outer ring 11 are arranged at the same height, and the elastic strips 1211 connect the binding portion 121 and the outer ring 11 in the radial direction of the outer ring 11, so that the connection points between the elastic strips 1211 and the binding portion 121 and the connection points between the elastic strips 1211 and the outer ring 11 are arranged in alignment, so that the binding portion 121 can move closer to or away from the outer ring 11 in the radial direction of the outer ring 11, thereby ensuring that the opening of the wearable device changes more evenly and stably, thereby better adapting to different wearing sizes and improving wearing comfort and fit; in another embodiment, such as Figure 10 As shown, in Figure 10Among them, three arrows that do not pass through the center of the ring represent the moving directions of the transient movement of the binding part 121 when it loses the external acting force. The inner ring 12 includes three binding parts 121 arranged at intervals. A fixed rotating shaft and an elastic strip 1211 are provided between each binding part 121 and the outer ring 11. One end of each fixed rotating shaft can be fixedly connected to the outer ring 11, and the other end is rotatably connected to the binding part 121. Both ends of all the elastic strips 1211 are respectively connected to a binding part 121 and the outer ring 11. Among them, all the elastic strips 1211 are arranged deviating from the center of the outer ring 11, and all the fixed rotating shafts are arranged through the center of the outer ring 11. In this way, during the process that the binding part 121 can gather or disperse relative to the outer ring 11, the binding part 121 can move along the non-radial direction of the outer ring 11. When worn, the first free end of the binding part 121 far from the fixed rotating shaft can deviate more from the outer ring 11, and the second free end of the binding part 121 close to the fixed rotating shaft can deviate more from the outer ring 11. Based on this, the electronic device 30 for detecting health can be fixed on the second free end, so that the electronic device 30 is closer to the human body to improve the detection accuracy; at the same time, because the distances between the first free end and the second free end and the center of the outer ring 11 are inconsistent, there is a certain gap between the worn limb and the wearing device, and this gap is beneficial to the heat dissipation of the wearing device.

[0067] In one embodiment, the inner peripheral surface of each binding part 121 is an arc surface, and all the arc surfaces are arranged on the same circumferential surface. In this way, when the binding parts 121 move relative to the outer ring 11, they can move towards or away from the outer ring 11 more smoothly to gather or disperse, making the change of the through-hole of the wearable device more uniform and stable, so as to better adapt to the limbs of different parts and improve the comfort and fit of wearing. At the same time, the arrangement of the binding parts 121 on the same circumferential surface also helps to maintain the overall beauty and consistency of the wearable device, making it more coordinated and natural in appearance during the wearing process, and further enhancing the practicality and decoration of the wearable device.

[0068] To enable each of the binding portions 121 to move toward or away from the outer ring 11 in the radial direction of the outer ring 11, the wearable device further includes a deformation assembly 20; all the binding portions 121 and the outer ring 11 enclose an activity space 10a, and the deformation assembly 20 is located in the activity space 10a; the deformation assembly 20 has a first connection portion 21a connected to the outer ring 11 and a second connection portion 21b connected to the inner ring 12; the first connection portion 21a can move closer to or away from the second connection portion 21b. Specifically, in one embodiment, the deformation assembly 20 includes a plurality of elastic members such as springs and rubber strips that can bend in the radial direction of the activity space 10a. Each elastic member is arranged circumferentially along the activity space 10a. Thus, when the binding portion 121 moves toward the outer ring 11, the elastic member that deforms (bends or compresses) always has a tendency to recover due to its physical properties. That is, the elastic member can apply a thrust to the binding portion 121 away from the outer ring 11, thereby ensuring the stability of the wearable device when worn; in another embodiment, please refer to Figure 11 and Figure 12 , the deformation assembly 20 is a deformation assembly 20 of an elastic member and a telescopic frame. The telescopic frame includes four rotating rods and two arc-shaped elastic strips. For the convenience of clear explanation, here it is defined that the four rotating rods are respectively the first rotating rod, the second rotating rod, the third rotating rod, and the fourth rotating rod, and the two arc-shaped elastic strips are the first elastic strip and the second elastic strip. The first rotating rod and the second rotating rod are rotatably connected, and the third rotating rod and the fourth rotating rod are rotatably connected. The two ends of the first elastic strip are respectively connected to the free ends of the first rotating rod and the third rotating rod, and the two ends of the second elastic strip are respectively connected to the free ends of the second rotating rod and the fourth rotating rod. At the same time, the connection point formed by the connection of the first rotating rod and the second rotating rod is fixedly connected to the inner peripheral wall of the outer ring 11, and the connection point formed by the connection of the third rotating rod and the fourth rotating rod is fixedly connected to the outer peripheral wall of the binding portion 121 (i.e., the peripheral wall facing the outer ring 11). Thus, when the binding portion 121 moves toward the outer ring 11, the first elastic strip and the second elastic strip can also apply a thrust to the binding portion 121 away from the outer ring 11; it can be understood that because the deformation assembly 20 is respectively connected to the two opposite sides of the outer ring 11 and the binding portion 121, when it is necessary to remove the wearable device, the outer ring 11 can be rotated, thereby driving the binding portion 121 to continue to move toward the outer ring 11. At this time, the aperture of the wearable device is larger than the size of the limb, so as to facilitate the removal of the wearable device.

[0069] Furthermore, the first connecting portions 21a and the second connecting portions 21b are distributed at intervals along the moving direction of the binding portion 121. Specifically, all the first connecting portions 21a and all the second connecting portions 21b of the deformation assembly 20 are arranged at the same height relative to the horizontal plane. Each first connecting portion 21a corresponds to a second connecting portion 21b. In this way, all the binding portions 121 move in central symmetry, avoiding the problem of structural breakage of the deformation assembly 20 due to the height difference between the first connecting portion 21a and the second connecting portion 21b during compression deformation. At the same time, the uniformity of the deformation of the deformation assembly 20 can be ensured, and the support effect can be ensured.

[0070] Furthermore, the deformation assembly 20 has a plurality of first deformation units 21, a plurality of first connecting portions 21a and a plurality of second connecting portions 21b. All the first deformation units 21 are distributed in the active space 10a along the circumferential direction of the inner peripheral wall of the outer ring 11. All the first connecting portions 21a are connected to the outer ring 11, and all the second connecting portions 21b are connected to the binding portion 121. Each first deformation unit 21 is provided with at least one first connecting portion 21a and at least one second connecting portion 21b. Specifically, in one embodiment, please refer to Figure 13 , the deformation assembly 20 has a first deformation unit 21 with a number not equal to one. The plurality of first deformation units 21 are arranged in the active space 10a at intervals and evenly. Each first deformation unit 21 is provided with a first connecting portion 21a with a number of one and a plurality of second connecting portions 21b with a number not equal to one. All the second connecting portions 21b of each first deformation unit 21 are connected to a binding portion 121. In this way, the connection stability between the first deformation unit 21 and the binding portion 121 can be improved. When a second connecting portion 21b of the first deformation unit 21 is disconnected from a binding portion 121, the first deformation unit 21 still has other second connecting portions 21b connected to this binding portion 121, extending the service life of the first deformation unit 21; In another embodiment, please refer to Figure 14, the deformation component 20 has a plurality of first deformation units 21 with a number not equal to one. The plurality of first deformation units 21 are spaced apart and evenly arranged in the active space 10a. Each first deformation unit 21 is provided with a plurality of first connection parts 21a with a number not equal to one and a plurality of second connection parts 21b with a number not equal to one. All the first connection parts 21a of each first deformation unit 21 are connected to an outer ring 11, and all the second connection parts 21b of each first deformation unit 21 are connected to a restraint part 121. In this way, the setting of multiple connection parts can effectively improve the connection stability between the first deformation unit 21 and the restraint part 121 and the outer ring 11. When a disconnection problem occurs between a second connection part 21b of the first deformation unit 21 and a restraint part 121 or between a first connection part 21a and the outer ring 11, the first deformation unit 21 still has other second connection parts 21b connected to this restraint part 121, or other first connection parts 21a connected to this outer ring 11, extending the service life of the first deformation unit 21. At the same time, the setting of multiple first connection parts 21a enables the user to pull back as much area of the restraint part 121 as possible at the moment of starting to rotate the outer ring 11 when rotating the outer ring 11, improving the response speed of the restraint part 121; it can be understood that the number of the first connection parts 21a and the second connection parts 21b of the first deformation unit 21 is not limited and can be adaptively set according to actual needs. Based on the above two embodiments, setting a plurality of first deformation units 21 and distributing them in the circumferential direction of the inner peripheral wall of the outer ring 11 in the active space 10a can ensure that the caliber of the through hole changes evenly, facilitating the wearing and removal of the wearable device proposed in this application.

[0071] In an embodiment of the present invention, each first deformation unit 21 includes at least one torsion spring 211 and at least four first rotating arms 212; all the first rotating arms 212 are rotatably connected end to end to form a polygonal ring structure; each torsion spring 211 is connected to two first rotating arms 212 that are close to the outer ring 11 and rotatably connected, and applies a force that makes the two first rotating arms 212 approach each other; the connection part of two first rotating arms 212 that are close to the outer ring 11 and rotatably connected forms a first connection part 21a, and the connection part of two first rotating arms 212 that are close to the restraint part 121 and rotatably connected forms a second connection part 21b. Specifically, please refer to Figure 15 and Figure 16, in this embodiment, the first deformation unit 21 includes a torsion spring 211 and four first rotating arms 212. The four first rotating arms 212 are sequentially connected end to end to form a closed polygonal ring structure. The four first rotating arms 212 are all in a straight segment structure. Thus, the polygonal ring structure is a quadrilateral structure. During the wearing process, the angle between the two first rotating arms 212 connecting the outer ring 11 and the binding section becomes larger, and the angle between the two first rotating arms 212 that are far from and not connected to the outer ring 11 and the binding section becomes smaller. The second connection point moves towards the first connection point. At this time, the torsion spring 211 undergoes a compressive deformation. When the outer ring 11 is rotated to remove the wearable device, the two ends of the torsion spring 211 further expand, so that the angle between the two first rotating arms 212 connecting the outer ring 11 and the binding section becomes larger, thereby realizing the function of pulling back the binding part 121. After the wearable device is completely removed and the binding part 121 loses the constraint of the limb, the internal stress of the torsion spring 211 can pull back the two first rotating arms 212 it connects, so that the angle between the two first rotating arms 212 connecting the outer ring 11 becomes smaller, thereby realizing the movement of pushing the binding part 121 away from the outer ring 11 by rotation, so that the wearable device enters the state with the smallest through-hole diameter, which is convenient for the same user to wear at another position, and can activate the stepless adjustment mechanism of the wearable device, thereby improving the applicable range of the wearable device; it can be understood that the closed polygonal ring structure formed by sequentially connecting end to end between four or more first rotating arms 212 is in the shape of a rhombus, pentagon, regular hexagon, etc.

[0072] In an embodiment of the present invention, the deformation assembly 20 further has a plurality of second deformation units 22 located in the activity space 10a. The first deformation unit 21 and the second deformation units 22 are alternately arranged and sequentially connected. Specifically, refer to Figure 13, each second deformation unit 22 includes two second elastic strips that are rotatably connected. Each second elastic strip abuts against an adjacent first elastic strip. In the circumferential direction of the active space 10a, a plurality of first deformation units 21 are connected in series by arranging a plurality of second deformation units 22. When a first deformation unit 21 undergoes abnormal deformation, the remaining first deformation units 21 and all second deformation units 22 can reduce the amount of deformation of the first deformation unit 21 through their own deformations, avoiding the problem of irreversible elastic deformation caused by abnormal deformation of a single first deformation unit 21, thereby improving the service life of the deformation assembly 20. It can be understood that the shape of the human bone is irregular. Taking the wrist as an example, there is a bone protrusion called "ulnar styloid process" on the side of the wrist close to the little finger, and a bone protrusion called "radial styloid process" on the side of the wrist close to the thumb, making the wrist an irregular ring. When the wearable device is worn at this time, at the protrusions of the "ulnar styloid process" and "radial styloid process", the first deformation units 21 and second deformation units 22 close to these two bone protrusions undergo relatively large deformations. At the same time, a plurality of second deformation units 22 connect a plurality of first deformation units 21 in series to form a ring shape for the deformation assembly 20. Through the plurality of second deformation units 22, the relatively large amount of deformation can be transferred to other places with smaller amounts of deformation, thereby improving the deformation uniformity of the deformation assembly 20 and the movement uniformity of the binding section, enabling the wearable device to fit more closely to the wrist. It can also be understood that when the wearable device is a smart ring, the size of the finger changes along the direction from the fingertip to the part where the finger connects to the palm. First, it gradually becomes larger to the joint, and then gradually becomes smaller to the part connecting to the palm (of course, the change amount in this section can be ignored). When the smart ring passes through the joint, the amounts of deformation of the first deformation units 21 and second deformation units 22 of the deformation assembly 20 change suddenly and become larger. The plurality of second deformation units 22 connecting the plurality of first deformation units 21 in series can evenly disperse the sudden change amount, thereby ensuring that when each binding part 121 moves closer to or away from the outer ring 11, the diameter of the through-hole can change evenly. Further, it can be understood that during the wearing process of the smart ring, the internal stress generated by the deformation assembly 20 can always drive the binding part 121 to move away from the outer ring 11. In this way, when passing through the finger joint, without manually adjusting the diameter of the through-hole, the smart ring can automatically fit the finger and stop at the appropriate wearing position. During the wearing process, the user does not need to perform other actions to adaptively fit the finger. During the removal process, the user can rotate the outer ring 11 or remove the wearable device without rotation, and the operation is extremely simple.

[0073] Further, reference can be made to Figure 15 and Figure 16, the second deformation unit 22 includes at least four second rotating arms 221; all the second rotating arms 221 are rotatably connected end to end to form a polygonal ring structure; the connection between two second rotating arms 221 that are close to the outer ring 11 and rotatably connected is spaced from the outer ring 11, and the connection between two second rotating arms 221 that are close to the outer ring 11 and rotatably connected is spaced from the restraint portion 121, and two second rotating arms 221 that are close to the first rotating arm 212 and rotatably connected are rotatably connected to the first rotating arm 212. Specifically, the layout of two second rotating arms 221 of the second deformation unit 22 and two first rotating arms 212 of the first deformation unit 21 at the rotating connection is: two first rotating arms 212 and two second rotating arms 221 are alternately and stacked in sequence, and along the vertical direction of the active space 10a, a structural layout of first rotating arm 212 - second rotating arm 221 - first rotating arm 212 - second rotating arm 221 is formed. Then, a rotating shaft or a pin is inserted vertically into the four rotating arms to realize the rotational connection between the four stacked rotating arms. In this way, when the first deformation unit 21 rotates, it can drive the second deformation unit 22 to rotate correspondingly.

[0074] In order to achieve the sealing of the wearable device, in an embodiment of the present invention, please refer to Figure 17 , the wearable device further includes a sealing soft rubber part 40. The sealing soft rubber part 40 includes a contact ring section 41 and two sealing sections 42. The contact ring section 41 and the sealing sections 42 are an integral structure. The two sealing sections 42 are respectively arranged at both ends in the axial direction of the contact ring section 41. The outer ring 11 has two inner side walls that are spaced apart along its axial direction. The end of the sealing section 42 is hermetically connected to the two inner side walls of the outer ring 11 to cooperate with the outer ring 11 to seal the active space 10a; all the restraint portions 121 and the deformation assembly 20 are located between the two sealing sections 42; the contact ring section 41 is located inside the circumference of all the restraint portions 121. Specifically, the wearable device has a three-layer structure from the outside to the inside. The outer layer is the outer ring 11, the middle layer is the inner ring 12, and the inner layer is the sealing soft rubber part 40. The outer ring 11 and the restraint section are both fixedly connected to the deformation assembly 20. The sealing section 42 extends into the active space 10a and is fixedly connected to the outer ring 11 to achieve sealing, so that the outer ring 11 and the sealing soft rubber part 40 form a closed space. This closed space falls within the range of the active space 10a. All the restraint sections and all the deformation assemblies 20 are located in the closed environment and are arranged close to the contact ring section 41. In this way, external dust and water vapor are blocked at the connection between the sealing section 42 and the outer ring 11 and cannot enter the closed space. During the wearing process, the finger presses the contact ring section 41 to push the inner ring 12 to move towards the outer ring 11, thereby realizing the stepless adjustment of the aperture of the wearable device and the sealing effect.

[0075] Further, please refer to Figure 18, the sealing section 42 has a foldable portion 421. A deformation gap is formed between the foldable portion 421 and at least one inner side wall of the outer ring 11. Specifically, the end of the sealing section 42 away from the contact ring section 41 is fixedly connected to the inner peripheral wall of the outer ring 11. There is a foldable portion 421 between the end of the sealing section 42 and the connection portion where the sealing section 42 connects to the contact ring section 41. The foldable portion 421 can be folded to form a plurality of uniform protrusions. At the same time, the foldable portion 421 and the inner side wall of the outer ring 11 are spaced apart to form a deformation gap. In this way, the protrusions formed after the foldable portion 421 is folded can abut against the inner side wall of the outer ring 11, further improving the sealing performance of the wearable device when in the worn state. At the same time, setting the foldable portion 421 can enable the sealing section 42 to deform uniformly, so as to ensure that the contact ring section 41 expands uniformly along the inner circumferential direction of the inner peripheral wall of the outer ring 11, making the contact ring section 41 fit the human body better and improving the wearing comfort of the wearable device.

[0076] In an embodiment of the present invention, the wearable device has at least two deformation components 20. The at least two deformation components 20 are spaced apart and form an installation space. The installation space is configured to accommodate the electronic device 30. In an embodiment, the wearable device has more than two deformation components 20. The multiple deformation components 20 are spaced apart along the vertical direction of the activity space 10a to divide the activity space 10a into multiple installation spaces. According to the functional requirements of the wearable device, the functional modules for realizing the functional requirements can be installed in different installation spaces. In this way, the complexity of the circuit setting can be reduced. At the same time, when a certain function of the wearable device fails, the maintainer can find the electronic device 30 in the installation space where he is located in the first time, thereby improving the maintenance efficiency.

[0077] In another embodiment, the wearable device is provided with two deformation components 20. The outer ring 11 has two inner side walls spaced apart along its axial direction. Each deformation component 20 is disposed close to one inner side wall. In this way, the interval between the two deformation components 20 is as small as possible. All the electronic devices 30 are located in the space formed by the two deformation components 20 and the inner peripheral wall of the outer ring 11, which can effectively improve the space utilization rate of the activity space 10a, so that more electronic devices 30 can be installed to realize more intelligent functions.

[0078] In an embodiment of the present invention, the wearable device is a smart ring. Due to the limited size of the smart ring itself, the installation space formed by it is limited. In this application, the stepless adjustment function of the smart ring can be realized by setting two spaced deformation components 20, thereby improving the applicable range. At the same time, the space between the two spaced deformation components 20 can accommodate more electronic devices 30. The electronic devices 30 are fixed on the inner side of the binding section, so as to realize electronic functions such as health monitoring, identity recognition, and human-computer interaction.

[0079] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
