DETAILED DESCRIPTION

[0008] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0009] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0010] The wearable device provided in the embodiments of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0011] refer to Figure 1-Figure 30 , a wearable device provided by an embodiment of the present application may include a device body 100 and temples 300. Figure 6 and Figure 7 As shown, the wearable device may include two temples 300, which are respectively connected to the two ends of the device body 100 and can be hung on the two ears of the user to wear the wearable device. For example, the wearable device can be smart glasses, of course, the wearable device can also be ordinary glasses.

[0012] like Figure 1 and Figure 30 As shown, the temple 300 may include a rigid portion 310, a flexible portion 320, a bending mechanism 340, and a driving mechanism 330. The rigid portion 310 may be connected to the device body 100, the flexible portion 320 may be connected to the rigid portion 310, the bending mechanism 340 may be disposed on the flexible portion 320, and the driving mechanism 330 may be disposed on the rigid portion 310. Furthermore, the driving mechanism 330 may drive the bending mechanism 340 to bend via a guide 350, thereby driving the flexible portion 320 to bend.

[0013] In the embodiment of the present application, the driving mechanism 330 drives the bending mechanism 340 to bend, so that the flexible portion 320 can be bent, so that the bending position and bending curvature of the flexible portion 320 can be accurately controlled, so that the overall shape and size of the temple 300 can be flexibly adjusted according to the size of the head 400 of different users, so as to fit the user's head 400 well, thereby reducing or eliminating the discomfort caused by the wearable device to the user, and at the same time effectively reducing the risk of the wearable device falling off during wearing, thereby effectively improving the wearing comfort of the user.

[0014] In an optional embodiment, the rigid portion 310 may include a first outer profile, and the flexible portion 320 may include a second outer profile. The first outer profile may enclose the drive mechanism 330, and the second outer profile may enclose the bending mechanism 340. The hardness of the first outer profile may be greater than that of the second outer profile, i.e., the first outer profile is less prone to bending. For example, the first outer profile may be made of metal or plastic, and the second outer profile may be made of silicone or sponge. Of course, both the first and second outer profiles may be made of silicone or sponge, but their hardness and elastic modulus may differ.

[0015] In an optional embodiment of the present application, Figure 1 and Figure 30As shown, the bending mechanism 340 may include an elastic frame 341 and at least two stoppers 342. One end of the elastic frame 341 may be connected to the rigid portion 310, and each stopper 342 may be connected to the elastic frame 341. Furthermore, the stoppers 342 may be distributed along the length of the elastic frame 341, with a movable space 343 defined between adjacent stoppers 342. In this embodiment, the elastic frame 341 inherently possesses a certain degree of elasticity and can bend and deform under external forces, thereby enabling the flexible portion 320 to bend, allowing the shape and size of the temple 300 to be flexibly adjusted to the size of different users' heads 400. The movable space 343 between adjacent stoppers 342 allows the elastic frame 341 to bend only within the range permitted by the movable space 343, thereby preventing damage to the elastic frame 341 due to excessive bending. For example, the width of the movable space 343 along the length of the elastic frame 341 may gradually increase from the elastic frame 341 to the stoppers 342. In this embodiment, the gradually increasing width of the movable space 343 provides more room for deformation for the elastic frame 341, making the elastic frame 341 easier to bend. Furthermore, due to the gradually increasing width of the movable space 343, after the elastic frame 341 is bent, the contact area between the limit blocks 342 is larger, thereby making the shape formed by the bending mechanism 340 more stable after bending, thereby ensuring a more stable shape of the flexible portion 320 after bending. Of course, the width of the movable space 343 along the length direction of the elastic frame 341 from the limit blocks 342 can also remain constant, gradually decrease, or change irregularly.

[0016] In other embodiments, the bending mechanism 340 may also only include the elastic frame 341 .

[0017] Alternatively, as Figure 1 and Figure 8 As shown, the bending mechanism 340 may include a plurality of limit blocks 342. A movable space 343 is formed between any two adjacent limit blocks 342. At least some of the movable spaces 343 have different angles, that is, at least some of the included angles between the limit blocks 342 are different. For example, the angle of the movable space 343 relative to the location where the elastic frame 341 is more bent can be increased, and the angle of the movable space 343 relative to the location where the elastic frame 341 is less bent can be decreased.

[0018] It should be noted that the maximum angle of the movable space 343 can be determined according to actual needs to prevent the elastic skeleton 341 from having a clamping problem due to an excessively large curvature.

[0019] In an optional embodiment, if Figure 12-13 、 Figure 16-17 、 Figure 19-20 、 Figure 22 As shown, the elastic skeleton 341 may include a first elastic skeleton 3411 and a second elastic skeleton 3412. The first elastic skeleton 3411 and the second elastic skeleton 3412 may be distributed along the length direction of the flexible part 320. The first end of the first elastic skeleton 3411 may be connected to the rigid part 310, and the first end of the second elastic skeleton 3412 may be connected to the second end of the first elastic skeleton 3411.

[0020] There are multiple limit blocks 342, which may include at least two first limit blocks 3421 and at least two second limit blocks 3422. Each first limit block 3421 can be set on one side of the first elastic skeleton 3411 in the first direction, and can be distributed along the length direction of the first elastic skeleton 3411. A first activity space 3431 can be formed between two adjacent first limit blocks 3421; each second limit block 3422 can be set on one side of the second elastic skeleton 3412 in the second direction, and can be distributed along the length direction of the second elastic skeleton 3412. A second activity space 3432 can be formed between two adjacent second limit blocks 3422. Here, the first direction intersects with the second direction. For example, the first direction and the second direction can be perpendicular to each other, so that the flexible portion 320 can be bent vertically and horizontally. For example, the first elastic skeleton 3411 can be bent vertically so that the flexible portion 320 forms a hanging ear fixation, such as Figure 7 As shown, the second elastic skeleton 3412 can bend horizontally to achieve the purpose of wrapping the back of the head and fixing it. In particular, the first elastic skeleton 3411 can bend in a first direction, thereby driving the flexible portion 320 wrapped around the first elastic skeleton 3411 to also bend in the first direction; the second elastic skeleton 3412 can bend in a second direction, thereby driving the flexible portion 320 wrapped around the second elastic skeleton 3412 to also bend in the second direction. In some embodiments, the first direction is also perpendicular to the second direction, the first direction is a vertical direction, and the second direction is a horizontal direction. In some embodiments, all limit blocks 342 have through holes 3420, and the through holes 3420 of all limit blocks 342 are interconnected, so that the guide member 350 can pass through each through hole 3420, connecting each limit block 342 in series, so that they move together under the action of the drive mechanism 330.

[0021] In this embodiment, the first limit block 3421 and the second limit block 3422 are respectively arranged in different directions of the first elastic skeleton 3411 and the second elastic skeleton 3412, and the width change directions of the first active space 3431 and the second active space 3432 are different, so that the bending mechanism 340 can bend in different directions, which can effectively improve the bending freedom of the bending mechanism 340, and thus enable the flexible part 320 to bend in different directions.

[0022] For example, along the first direction, the width of the first movable space 3431 along the length of the first elastic skeleton 3411 can gradually increase. In this embodiment, the gradually increasing width of the first movable space 3431 can provide the first elastic skeleton 3411 with more ample deformation space, making the first elastic skeleton 3411 easier to bend. Moreover, due to the gradually increasing width of the first movable space 3431, after the first elastic skeleton 3411 is bent, the contact area between the first limit blocks 3421 is larger, thereby making the shape formed by the bending mechanism 340 more stable after bending, thereby ensuring a more stable shape of the flexible portion 320 after bending. Of course, along the first direction, the width of the first movable space 3431 along the length of the first elastic skeleton 3411 can also remain unchanged, gradually decrease, or change irregularly.

[0023] Along the second direction, the width of the second movable space 3432 along the length of the second elastic skeleton 3412 can gradually increase. In this embodiment, the gradually increasing width of the second movable space 3432 provides the second elastic skeleton 3412 with more ample deformation space, making it easier for the second elastic skeleton 3412 to bend. Furthermore, due to the gradually increasing width of the second movable space 3432, after the second elastic skeleton 3412 is bent, the contact area between the second limiting blocks 3422 is larger, thereby making the shape formed by the bending mechanism 340 more stable after bending, thereby ensuring a more stable shape of the flexible portion 320 after bending. Of course, along the second direction, the width of the second movable space 3432 along the length of the second elastic skeleton 3412 can also remain unchanged, gradually decrease, or change irregularly.

[0024] like Figure 22 As shown, the first elastic skeleton 3411 can be bent along the direction indicated by arrow c, as shown in FIG. Figure 19 and Figure 23 As shown, the second elastic skeleton 3412 can be bent along the direction indicated by arrow d, as shown in FIG. Figure 20 、 Figure 24 and Figure 26 As shown, the first elastic skeleton 3411 can be bent in the direction indicated by arrow c, and the second elastic skeleton 3412 can be bent in the direction indicated by arrow d. Here, the direction indicated by arrow c and the direction indicated by arrow d can intersect.

[0025] In other embodiments, the first limiting block 3421 and the second limiting block 3422 may be located on the same side.

[0026] Optionally, the cross-sectional shape of the elastic skeleton 341 in the direction perpendicular to the length of the elastic skeleton 341 can be circular, which is conducive to ensuring that the elastic skeleton 341 is subjected to uniform force. However, since the circular cross-section has a constant radius of curvature, when subjected to force, its bending deformation is mainly evenly distributed along the entire cross-section, and only overall consistent bending can be achieved, which leads to low flexibility in curvature control of the elastic skeleton 341.

[0027] In order to improve the flexibility of controlling the curvature of the elastic skeleton 341, the elastic skeleton 341 can be set to a special-shaped structure. For example, the elastic skeleton 341 can be a polygonal structure. For example, Figure 20 and Figure 24 As shown, the elastic skeleton 341 can be a rectangular or hexagonal structure. Because the polygonal structure has different geometric shapes in different directions, it can bend to varying degrees in different directions when subjected to force. For example, the elastic skeleton 341 has higher rigidity and lower curvature in the direction of its wider sides, while it has higher flexibility and higher curvature in the direction of its narrower sides, which is suitable for multi-directional bending requirements.

[0028] It should be noted that the direction of the narrower sides of the first elastic skeleton 3411 and the second elastic skeleton 3412 can be set as the direction that needs to be bent, and the extension direction of each first activity space 3431 and each second activity space 3432 can be adjusted so that the elastic skeleton 341 can achieve multiple bending.

[0029] In some embodiments, the elastic skeleton 341 may further include a third elastic skeleton 3413. The first end of the first elastic skeleton 3411 may be connected to the rigid portion 310 via the third elastic skeleton 3413. In this configuration, the third elastic skeleton 3413 can serve as a connection between the first elastic skeleton 3411 and the rigid portion 310. Optionally, the thickness of the third elastic skeleton 3413 is greater than that of the first elastic skeleton 3411. This can improve the structural strength of the elastic skeleton 341 and increase the connection area between the elastic skeleton 341 and the rigid portion 310, thereby improving the connection stability between the elastic skeleton 341 and the rigid portion 310.

[0030] Further optionally, the third elastic skeleton 3413 may be provided with a connecting hole 34131 , the connecting hole 34131 may be communicated with the through hole 3420 below, and the guide member 350 may pass through the connecting hole 34131 and be disposed in the through hole 3420 .

[0031] In an optional embodiment, if Figure 1 、 Figures 8-10 and Figure 30As shown, the limit block 342 is provided with a through hole 3420, and the guide member 350 is passed through the through hole 3420. In this way, the through hole 3420 can position and constrain the guide member 350, so that the guide member 350 can only move along a set path, and thus the elastic frame 341 can only bend along the set path, thereby preventing the bending direction of the elastic frame 341 from deviating.

[0032] Of course, the limit block 342 may not be provided with the through hole 3420, and the guide member 350 may not be passed through the limit block 342. For example, when the guide member 350 includes a pull rope, one end of the pull rope may be located outside the limit block 342, and one end of the pull rope may directly bypass the limit block 342 and be connected to the end of the elastic skeleton 341 away from the rigid part 310.

[0033] In an optional embodiment, as Figure 1 、 Figure 2 、 Figures 8-10 As shown, the guide member 350 may include a pull rope, which may be passed through the through hole 3420. The first end of the pull rope may be connected to the end of the elastic frame 341 away from the rigid part 310 or the limit block 342 away from the rigid part 310. The driving mechanism 330 may be connected to the second end of the pull rope and used to retract and release the pull rope. In this embodiment, the pull rope is connected to the end of the elastic frame 341 away from the rigid part 310 or the limit block 342 away from the rigid part 310, as shown in FIG. Figure 2 As shown, when the driving mechanism 330 pulls the pull rope, the pull rope can be moved along Figure 2 When the pull cord moves in the direction indicated by arrow a, it exerts tension on the elastic frame 341, causing it to bend. When the drive mechanism 330 releases the pull cord, the elastic frame 341 returns to its original shape due to its own elasticity. Because the pull cord is lightweight and inexpensive, it can effectively reduce the weight and manufacturing cost of the wearable device.

[0034] Of course, the guide member 350 may not include a pull rope. For example, the guide member 350 may include a fluid, and the flow of the fluid generates pressure to drive the bending of the elastic skeleton 341.

[0035] In an optional embodiment, if Figure 1 and Figure 3As shown, the driving mechanism 330 may include a slider 333, a first screw 332 and a first driving motor 331. The slider 333 may be slidably connected to the rigid portion 310, the slider 333 may be connected to the second end of the pull rope, the first screw 332 may be threadedly connected to the slider 333, and the first driving motor 331 may be connected to the first screw 332 and may be used to drive the first screw 332 to rotate, thereby driving the slider 333 to move along the length direction of the rigid portion 310. In this embodiment, when the first driving motor 331 drives the first screw 332 to rotate, the slider 333 performs precise linear motion along the axis direction of the first screw 332. The slider 333 may move along the axis direction of the first screw 332. Figure 2 The first drive motor 331 moves in the direction indicated by arrow b, causing the pull cord to move in the direction indicated by arrow a, thereby pulling the elastic frame 341 to bend. By controlling the rotation angle and speed of the first drive motor 331, the movement distance and speed of the slider 333 can be precisely controlled, thereby precisely controlling the retracted and extended length of the pull cord, thereby achieving precise adjustment of the bending angle of the elastic frame 341. Furthermore, by driving the movement of the slider 333 by the first drive motor 331, the bending mechanism 340 can be automatically bent, thereby achieving automatic bending of the flexible portion 320.

[0036] In other embodiments, the driving mechanism 330 may not include the first driving motor 331 . When the bending angle of the bending mechanism 340 needs to be adjusted, the user may manually rotate the first screw 332 .

[0037] Alternatively, the drive mechanism 330 may not include the first screw 332 and the first drive motor 331. For example, the drive mechanism 330 may include a telescopic drive member, which may be connected to the slider 333, and the movement of the slider 333 is achieved by the telescopic drive member extending and retracting. Here, the telescopic drive member may be a cylinder, a hydraulic cylinder, or other telescopic structure.

[0038] Alternatively, as Figure 1 and Figure 2 As shown, the driving mechanism 330 may further include a guide rod 334, which may be fixedly mounted on the rigid portion 310 and parallel to the first screw 332. Furthermore, the slider 333 may be slidably connected to the guide rod 334. This arrangement can both guide and restrict the slider 333, thereby limiting its circumferential rotation and ensuring that the slider 333 can only move along the axial direction of the first screw 332.

[0039] Of course, the driving mechanism 330 may not include the guide rod 334 .

[0040] In some embodiments, as Figure 1 and Figure 2As shown, the rigid portion 310 may further include a first fixing plate 335 and a second fixing plate 336. The first fixing plate 335 may be fixedly connected to the housing of the first drive motor 331. The second fixing plate 336 may be located at the end of the first screw 332 facing away from the first drive motor 331, and the end of the first screw 332 facing away from the first drive motor 331 is rotatably connected to the second fixing plate 336. Here, the second fixing plate 336 may support and limit the first screw 332. The two ends of the guide rod 334 may be connected to the first fixing plate 335 and the second fixing plate 336, respectively. Here, the first fixing plate 335 and the second fixing plate 336 may support and fix the guide rod 334. Optionally, one end of the elastic frame 341 may be connected to the second fixing plate 336 to connect the elastic frame 341 to the rigid portion 310. Furthermore, the second fixing plate 336 may be provided with a perforation, through which one end of the guide member 350 may pass to connect to the slider 333.

[0041] In this embodiment, the first drive motor 331 drives the first screw 332 to rotate, and the first screw 332 drives the slider 333 to move along the length direction of the rigid portion 310. The movement of the slider 333 can retract and release the pull rope, thereby driving the elastic frame 341 to bend. For example, the front portion of the flexible portion 320 can wrap around the first elastic frame 3411 and the first limit block 3421, and the rear portion of the flexible portion 320 can wrap around the second elastic frame 3412 and the second limit block 3422. Here, the front portion of the flexible portion 320 can be the portion close to the rigid portion 310, and the rear portion of the flexible portion 320 can be the portion away from the rigid portion 310.

[0042] Specifically, when the first drive motor 331 drives the first screw 332 to rotate forward, the first screw 332 can drive the slider 333 to move in the direction close to the first drive motor 331, so that the slider 333 tightens the pull rope, the second limit blocks 3422 approach each other, and the second elastic skeleton 3412 bends horizontally, and drives the tail of the flexible portion 320 to bend horizontally until the tail of the flexible portion 320 fits the user's head 400; then, the first drive motor 331 continues to rotate forward, so that the slider 333 continues to tighten the pull rope, at this time The tail of the flexible portion 320 is restricted by the user's head 400 and can no longer bend in the horizontal direction, that is, the second elastic skeleton 3412 can no longer bend in the horizontal direction. As the pull rope continues to be tightened, the first limit blocks 3421 approach each other, and the first elastic skeleton 3411 bends vertically, and drives the front of the flexible portion 320 to bend vertically until the front of the flexible portion 320 fits against the back of the user's ear, that is, the flexible portion 320 forms an ear hook structure. At this time, the first drive motor 331 stops, causing the slider 333 to stop moving.

[0043] When the first drive motor 331 drives the first screw 332 to reverse, the first screw 332 can drive the slider 333 to move away from the first drive motor 331, so that the slider 333 releases the pull rope. At this time, the second elastic skeleton 3412 gradually recovers its deformation, that is, gradually straightens, and drives the second limit blocks 3422 to move away from each other, thereby straightening the tail of the flexible portion 320 gradually until the second elastic skeleton 3412 returns to its initial state, that is, the second elastic skeleton 3412 becomes straight, thereby driving the flexible portion 320 to return to its initial state. The tail of the flexible portion 320 becomes straight; then, the first drive motor 331 continues to reverse, causing the slider 333 to continue to loosen the pull rope. As the pull rope continues to loosen, the first elastic skeleton 3411 gradually recovers its deformation, that is, gradually straightens, and drives the first limit blocks 3421 away from each other, thereby causing the front of the flexible portion 320 to gradually straighten until the first elastic skeleton 3411 returns to its initial state, that is, the first elastic skeleton 3411 becomes straight. At this time, the first drive motor 331 stops, causing the slider 333 to stop moving.

[0044] In another optional embodiment, as Figure 30 As shown, the flexible portion 320 may be provided with a first sealed cavity 321, the elastic frame 341 and the stopper 342 may be located within the first sealed cavity 321, the movable space 343 may be in communication with the through-hole 3420, and the guide 350 may include a fluid that can flow in and out of the movable space 343 to adjust the size of the movable space 343. In this embodiment, when fluid is injected into the movable space 343, the size of the movable space 343 increases, thereby limiting the bending of the elastic frame 341. When the fluid is removed, the size of the movable space 343 decreases, increasing the bending space of the elastic frame 341 and the degree of bending. In this way, by precisely controlling the amount of fluid flowing in and out of the movable space 343, the degree of bending of the elastic frame 341 can be precisely adjusted. Compared to adjusting the bending degree of the elastic frame 341 by retracting and releasing a drawstring, adjusting the bending degree of the elastic frame 341 using fluid is less likely to cause wear on the stopper 342 and less likely to malfunction, thereby helping to ensure the service life of the temple 300.

[0045] Here, the fluid may be gas or liquid.

[0046] In other embodiments, the flexible portion 320 may not be provided with the first sealed cavity 321, and the guide member 350 may not include fluid. For example, the guide member 350 may include a drawstring.

[0047] Optionally, the limit block 342 can be sealed and connected to the cavity wall of the first sealed cavity 321. Such a setting allows the fluid to enter and exit the activity space 343 only through the through hole 3420, thereby making it easier for the fluid to adjust the size of the activity space 343, thereby ensuring that the elastic skeleton 341 can bend according to the set path.

[0048] Of course, the limiting block 342 may not be sealed to the cavity wall of the first sealed cavity 321 .

[0049] In an optional embodiment, if Figure 30 As shown, the rigid portion 310 may be provided with a second sealed cavity 311, which may be in communication with the movable space 343. For example, when the stopper 342 is sealedly connected to the cavity wall of the first sealed cavity 321, the second sealed cavity 311 may be in communication with the movable space 343 via the through hole 3420. When the stopper 342 is not sealedly connected to the cavity wall of the first sealed cavity 321, the second sealed cavity 311 may be in communication with the movable space 343 via the through hole 3420 and the gap between the stopper 342 and the cavity wall of the first sealed cavity 321. The driving mechanism 330 may include a piston 337 and a driving assembly 338 connected to the piston 337. The piston 337 is movably disposed in the second sealed cavity 311. The driving assembly 338 may be used to drive the piston 337 to move along the length direction of the rigid portion 310 to allow fluid to enter and exit the movable space 343 and the second sealed cavity 311. In this embodiment, the pressure in the first sealed cavity 321 and the second sealed cavity 311 can be adjusted by the movement of the piston 337, allowing fluid to flow between the first sealed cavity 321 and the second sealed cavity 311, thereby adjusting the degree of curvature of the flexible portion 320. For example, when the driving assembly 338 drives the piston 337 to move from the flexible portion 320 to the rigid portion 310, the fluid in the movable space 343 will flow into the second sealed cavity 311, reducing the size of the movable space 343 and moving the stoppers 342 closer to each other, thereby causing the elastic frame 341 to deform and bend, thereby causing the flexible portion 320 to bend. When the driving assembly 338 drives the piston 337 to move from the rigid portion 310 to the flexible portion 320, the fluid in the second sealed cavity 311 will flow into the first sealed cavity 321 and into the movable space 343, increasing the size of the movable space 343 and moving the stoppers 342 away from each other, thereby reducing the curvature of the elastic frame 341, thereby reducing the curvature of the flexible portion 320, or even straightening it. Moreover, the movement of the piston 337 is used to achieve the movement of the fluid. Compared with the method of using a driving pump to suck the fluid, the structure is simple, the space occupied is small, and the weight is light, which is conducive to miniaturization of the wearable device and reduction of the weight of the wearable device.

[0050] In other embodiments, the driving mechanism 330 may not include the piston 337 . For example, the driving mechanism 330 may include a driving pump, which may be in communication with the first sealed chamber 321 and capable of pumping fluid.

[0051] In an optional embodiment, if Figure 30As shown, the drive assembly 338 may include a second screw 3382 and a second drive motor 3381. The second screw 3382 may be connected to the piston 337. The second drive motor 3381 may be connected to the second screw 3382 and may be used to drive the second screw 3382 to rotate, thereby driving the piston 337 to move. In this embodiment, the rotation of the second screw 3382 driven by the second drive motor 3381 can achieve automatic bending of the bending mechanism 340, and thus achieve automatic bending of the flexible portion 320. Compared to using a pneumatic cylinder or a hydraulic cylinder as a power source, using the second drive motor 3381 as a power source does not require an additional pneumatic or hydraulic source, and only electrical energy can be used to provide power. This also helps to reduce the space occupied by the drive assembly 338 and reduce the weight of the drive assembly 338.

[0052] In this embodiment, the second drive motor 3381 drives the second screw 3382 to rotate, and the second screw 3382 drives the piston 337 to move along the length of the rigid portion 310. The movement of the piston 337 can adjust the pressure of the first sealed cavity 321 and the second sealed cavity 311, allowing fluid to flow between the first sealed cavity 321 and the second sealed cavity 311, thereby driving the elastic frame 341 to bend. Exemplarily, the front portion of the flexible portion 320 wraps around the first elastic frame 3411 and the first limit block 3421, and the rear portion of the flexible portion 320 wraps around the second elastic frame 3412 and the second limit block 3422. Here, the front portion of the flexible portion 320 can be the portion close to the rigid portion 310, and the rear portion of the flexible portion 320 can be the portion away from the rigid portion 310.

[0053] Specifically, when the second drive motor 3381 drives the second screw 3382 to rotate forward, the second screw 3382 can drive the piston 337 to move toward the second drive motor 3381, thereby reducing the pressure in the second sealed chamber 311, and then allowing the fluid in the first sealed chamber 321 to flow into the second sealed chamber 311, so that the size of the second activity space 3432 gradually decreases, and the second limit blocks 3422 approach each other, and drive the second elastic skeleton 3412 to bend horizontally, thereby driving the tail of the flexible portion 320 to bend horizontally until the tail of the flexible portion 320 fits the user's head 400; then, the second drive motor 3381 continues to rotate forward, causing the piston 337 to continue to move. Continue to move in the direction close to the second drive motor 3381. At this time, the tail of the flexible part 320 is restricted by the user's head 400 and can no longer bend in the horizontal direction, that is, the second elastic skeleton 3412 can no longer bend in the horizontal direction. As the fluid gradually flows into the second sealed cavity 311, the size of the first activity space 3431 gradually decreases, and the first limit blocks 3421 approach each other, and drive the first elastic skeleton 3411 to bend vertically, thereby driving the front part of the flexible part 320 to bend vertically, until the front part of the flexible part 320 fits against the back side of the user's ear, that is, the flexible part 320 forms an ear hook structure. At this time, the second drive motor 3381 stops, and the piston 337 stops moving.

[0054] When the second drive motor 3381 drives the second screw 3382 to reverse, the second screw 3382 can drive the piston 337 to move away from the second drive motor 3381, thereby increasing the pressure in the second sealed chamber 311, and then causing the fluid in the second sealed chamber 311 to flow into the first sealed chamber 321. At this time, the fluid gradually enters the first active space 3431, thereby increasing the size of the first active space 3431, and the first limit blocks 3421 move away from each other, thereby driving the first elastic skeleton 3411 to gradually restore the deformation, that is, the first elastic skeleton 3411 gradually straightens, thereby causing the front of the flexible part 320 to gradually straighten, until the first elastic skeleton 3411 returns to its initial state, that is, the first elastic skeleton 3411 straightens, thereby driving the front of the flexible part 320 to straighten. Straight; then, the second drive motor 3381 continues to reverse, causing the piston 337 to continue to move away from the second drive motor 3381. At this time, the fluid in the second sealed chamber 311 continues to flow into the first sealed chamber 321. Since the size of the first active space 3431 has reached its maximum, the fluid flows into the second active space 3432, causing the size of the second active space 3432 to increase, and the second limit blocks 3422 move away from each other, thereby driving the second elastic skeleton 3412 to gradually restore its deformation, that is, the second elastic skeleton 3412 gradually straightens, thereby causing the tail of the flexible portion 320 to gradually straighten until the second elastic skeleton 3412 returns to its initial state, that is, the second elastic skeleton 3412 straightens, and at this time the second drive motor 3381 stops, causing the piston 337 to stop moving.

[0055] Alternatively, as Figure 30 As shown, the piston 337 may be provided with a piston rod 3371 at one end facing the second drive motor 3381. The piston rod 3371 may be provided with a threaded hole that may be threadedly connected to the second screw 3382. Furthermore, to prevent relative rotation between the piston 337 and the second sealed chamber 311, the piston 337 and the cavity wall of the second sealed chamber 311 cooperate to limit the circumference of the second screw 3382. For example, the piston 337 and the second sealed chamber 311 may both be provided with mutually cooperating limiting surfaces. For example, the piston 337 and the second sealed chamber 311 may both be polygonal.

[0056] In other embodiments, the driving assembly 338 may not include the second driving motor 3381 , and the user may manually rotate the second screw 3382 to move the piston 337 .

[0057] Alternatively, the drive assembly 338 may not include the second drive motor 3381 and the second screw 3382. The drive assembly 338 may include a telescopic drive member that can be connected to the piston 337 and drive the piston 337 to move. Exemplarily, the telescopic drive member can be a cylinder or a hydraulic cylinder or other telescopic member.

[0058] In some embodiments, as Figure 30 As shown, a connecting skeleton 360 can be provided in the rigid part 310, and the connecting skeleton 360 can serve as a part of the cavity wall of the second sealed cavity 311, and the connecting skeleton 360 can be connected to the elastic skeleton 341. Such a setting can realize the connection between the elastic skeleton 341 and the rigid part 310, and is conducive to dispersing the force of the elastic skeleton 341 to other positions of the rigid part 310.

[0059] In an optional embodiment of the present application, Figure 3-Figure 5 As shown, the elastic skeleton 341 may include at least two skeleton segments 3410 , each skeleton segment 3410 may be connected in sequence along the length direction of the flexible portion, and one end of the skeleton segment 3410 close to the rigid portion may be connected to the rigid portion 310 .

[0060] Among them, Figure 3 As shown, the bending modulus of each skeleton segment 3410 is different, and / or, as shown Figure 5 As shown, the tapers of the skeleton segments 3410 are different. This arrangement enables different positions of the elastic skeleton 341 to achieve different bending degrees, thereby enabling different positions of the flexible portion 320 to achieve different bending degrees.

[0061] In other embodiments, the bending modulus of each skeleton segment 3410 may also be the same, and / or the taper of each skeleton segment 3410 may also be the same.

[0062] Alternatively, as Figure 3-Figure 5 As shown, the number of skeleton segments 3410 can be multiple, which may include a first skeleton segment 34101, a second skeleton segment 34102 and a third skeleton segment 34103. The first skeleton segment 34101, the second skeleton segment 34102 and the third skeleton segment 34103 can be connected in sequence along the length direction of the flexible part 320, and one end of the first skeleton segment 34101 is connected to the rigid part 310.

[0063] The bending moduli of the first skeleton segment 34101, the second skeleton segment 34102, and the third skeleton segment 34103 may be different, and / or the tapers of the first skeleton segment 34101, the second skeleton segment 34102, and the third skeleton segment 34103 may be different. This configuration allows the three locations of the elastic skeleton 341 to achieve different degrees of bending, and thus allows the three locations of the flexible portion 320 to achieve different degrees of bending.

[0064] For example, Figure 3As shown, the bending modulus of the first skeleton segment 34101 can be greater than that of the third skeleton segment 34103, and the bending modulus of the third skeleton segment 34103 can be greater than that of the second skeleton segment 34102. This configuration can make the second skeleton segment 34102 easier to bend, and thus, when bending the flexible portion 320, the middle portion of the flexible portion 320 can be bent first, and then the portion of the flexible portion 320 away from the rigid portion 310 can be bent. Of course, the bending moduli of the first skeleton segment 34101, the second skeleton segment 34102, and the third skeleton segment 34103 can also be reduced in sequence, so that the third skeleton segment 34103 can be more easily bent.

[0065] like Figure 4 As shown, the tapers of the first skeleton segment 34101, the second skeleton segment 34102, and the third skeleton segment 34103 can increase in sequence. This arrangement makes the third skeleton segment 34103 easier to bend. Consequently, when bending the flexible portion 320, the middle portion of the flexible portion 320 can bend first, followed by bending at a position away from the rigid portion 310. Controlling the taper of multiple skeleton segments enables varying degrees of gradual bending control of the elastic skeleton 341. For example, if the taper of the third skeleton segment 34103 changes more rapidly than that of the second skeleton segment 34102, the third skeleton segment 34103 is easier to bend than the second skeleton segment 34102. It should be noted that the steeper the taper, the greater the difference in the degree of bending between the skeleton segments, while the gentler the taper, the smaller the difference in bending between the skeleton segments 3410.

[0066] In an optional embodiment, if Figure 5 As shown, each skeleton segment 3410 can be provided with a plurality of annular grooves, and each annular groove can be spaced apart along the length direction of the skeleton segment 3410. The thickness of the portion surrounded by the annular groove of each skeleton segment 3410 can be different. This arrangement can enable different positions of the elastic skeleton 341 to achieve different degrees of bending.

[0067] For example, the first skeleton segment 34101 can be provided with a plurality of first annular grooves 34104, the first annular grooves 34104 are coaxial with the first skeleton segment 34101, and the first annular grooves 34104 are spaced apart along the length direction of the first skeleton segment 34101; the second skeleton segment 34102 can be provided with a plurality of second annular grooves 34105, the second annular grooves 34105 are coaxial with the second skeleton segment 34102, and the second annular grooves 34105 are spaced apart along the length direction of the second skeleton segment 34102; and the third skeleton segment 34103 can be provided with a plurality of second annular grooves 34105. 4103 can be provided with a plurality of third annular grooves 34106, which are coaxial with the third skeleton segment 34103, and the third annular grooves 34106 are spaced apart along the length direction of the third skeleton segment 34103, and the inner diameters of the first annular groove 34104, the second annular groove 34105 and the third annular groove 34106 are different, so that the thickness of the part surrounded by the first annular groove 34104, the thickness of the part surrounded by the second annular groove 34105 and the thickness of the part surrounded by the third annular groove 34106 are different. For example, the inner diameter of the first annular groove 34104 is larger than the inner diameter of the third annular groove 34106, and the inner diameter of the third annular groove 34106 is larger than the inner diameter of the second annular groove 34105. This makes the thickness of the portion surrounded by the second annular groove 34105 thinner than the thicknesses of the other two portions. This, in turn, makes the second skeleton segment 34102 easier to bend. When bending the flexible portion 320, the middle portion of the flexible portion 320 can be bent first, and then the portion away from the rigid portion 310 can be bent. Of course, the inner diameter of the first annular groove 34104 can also be larger than the inner diameter of the second annular groove 34105, and the inner diameter of the second annular groove 34105 can also be larger than the inner diameter of the third annular groove 34106. Specifically, the inner diameters of the first annular groove 34104, the second annular groove 34105, and the third annular groove 34106 can be set according to actual needs.

[0068] Optionally, the elastic skeleton 341 and the limit blocks 342 can be made of the same material, and the elastic skeleton 341 and the limit blocks 342 can be an integrated structure. Exemplarily, the bending mechanism 340 can be an integrated flexible portion skeleton, and the flexible portion skeleton can be provided with multiple grooves of different depths to form the elastic skeleton 341 and multiple limit blocks 342 on the flexible portion skeleton, and the deeper the groove, the thinner the thickness of the portion of the elastic skeleton 341 corresponding to the groove, making this portion of the elastic skeleton 341 more easily deformable; and the shallower the groove, the thicker the thickness of the portion of the elastic skeleton 341 corresponding to the groove, making this portion of the elastic skeleton 341 less easily deformable.

[0069] In an optional embodiment, the temple 300 can be designed to conform to the shape of the user's head 400 by controlling the bending position and curvature of the elastic skeleton 341. The radius of curvature R of the elastic skeleton 341 is related to the bending moment M, the material elastic modulus E, and the section moment of inertia I, using the following relationship: 1 / R = M / (EI). A higher EI value indicates greater rigidity, a smaller curvature, and a gentler bend; a lower EI value indicates greater flexibility, a larger curvature, and a steeper bend. By adjusting the EI value at each bending position of the elastic skeleton 341, a specific curvature distribution can be achieved.

[0070] In an optional embodiment of the present application, Figure 27-Figure 29 As shown, the wearable device may further include an arm 200, one end of which may be connected to the device body 100, and a temple 300 may include a first temple 301 and a second temple 302. The rigid portion 310 of the first temple 301 and the rigid portion 310 of the second temple 302 may both be connected to the other end of the arm 200, and an angle may be provided between the first temple 301 and the second temple 302. In this embodiment, since the temple 300 includes the first temple 301 and the second temple 302, during the wearing process of the wearable device, the force applied by the wearable device may be dispersed to different positions of the head 400 via the first temple 301 and the second temple 302, thereby reducing the pressure of the wearable device on the nose bridge and the ears, thereby improving wearing comfort.

[0071] In other embodiments, the temple 300 may also only include the first temple 301 or the second temple 302 .

[0072] In some embodiments, the wearable device may not include the temple 200, and the rigid portion 310 of the temple 300 may be directly connected to the device body 100. In addition, the rigid portion 310 may be arranged between the device body 100 and the user's ear, and the flexible portion 320 of the temple 300 is connected to the rigid portion 310. The flexible portion 320 may be bent and fit the back of the user's head through the driving mechanism 330.

[0073] Optionally, the temple 300 may also include at least two first temples 301 or at least two second temples 302, and each first temple 301 and each second temple 302 may include a driving mechanism 330, that is, each first temple 301 and each first temple 301 can control their respective bending strokes through the driving mechanism 330 to achieve a suitable degree of tightness.

[0074] In an optional embodiment, if Figure 27 As shown, both the first temple 301 and the second temple 302 can be used to act on the back of the head. This arrangement can disperse the force of the wearable device to the back of the head.

[0075] Or, as Figure 28 As shown, the first temple 301 can be used to act on the top of the head, and the second temple 302 can be used to act on the back of the head. In this way, the force of the wearable device can be dispersed to the top of the head and the back of the head.

[0076] Or, as Figure 29 As shown, the first temple 301 can be used to act on the forehead, and the second temple 302 can be used to act on the back of the head. In this way, the force of the wearable device can be dispersed to the forehead and the back of the head.

[0077] In an optional embodiment, if Figure 27 As shown, a flexible connector 303 may be provided between the first temple 301 and the second temple 302. This arrangement can increase the contact area between the temple 300 and the head 400, thereby further improving the wearing comfort.

[0078] Here, the flexible connector 303 may be a woven fabric or elastic foam skin, or other flexible structures.

[0079] For example, when the first temple 301 and the second temple 302 both act on the back of the head, a flexible connector 303 is provided between the first temple 301 and the second temple 302. This arrangement can reduce the occupied area of the temple 300 and prevent the temple 300 from covering a large area of the head 400 and reducing the aesthetics.

[0080] Of course, no flexible connector may be provided between the first temple 301 and the second temple 302 .

[0081] In an optional embodiment of the present application, the wearable device may further include a detection element, which may be used to detect or identify the user's usage scenario, and the detection element may be in communication with a drive mechanism 330, and the drive mechanism 330 may adjust the degree of bending of the flexible portion 320 of the temple 300 according to a detection signal from the detection element. For example, when the user is running, the detection element detects that the user is in a running state. At this time, the drive mechanism 330 automatically controls the flexible portion 320 of the temple 300 to bend according to the detection signal of the detection element, so that the temple 300 is further contracted and fixed, preventing the wearable device from shaking or falling when the user is running. When the running state ends, the drive mechanism 330 automatically controls the flexible portion 320 of the temple 300 to return to its initial state according to the detection signal of the detection element to prevent squeezing the user's head 400. This enables the wearable device to distinguish the user's usage scenario and realize intelligent adjustment of the temple 300, achieving the optimal dynamic balance between comfort and firmness.

[0082] Optionally, when the user wears the wearable device for the first time, the user can manually adjust the temple 300 to a comfortable position. At this time, the driving mechanism 330 can accurately record the movement stroke of the slider 333 or the piston 337, that is, record the position of the slider 333 or the piston 337, so that the next time the wearable device is worn, the driving mechanism 330 can automatically adjust the slider 333 or the piston 337 to the desired position, so that the flexible portion 320 is automatically adjusted to a comfortable position for the user.

[0083] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
