[0037] This application provides an adjustment device for a wearable device. The wearable device may specifically include at least one of a smart helmet and smart glasses; however, this application does not limit the specific type of the wearable device.

[0038] Reference Figure 1 The diagram shows a structural schematic of a wearable device according to an embodiment of this application. Figure 2 , showed Figure 1 The exploded view of the wearable device shown is for reference only. Figure 3 , showed Figure 1 The diagram shows a cross-sectional structure of the wearable device. Figure 1 As shown, the wearable device may specifically include: a device body 10, a first strap 20, a second strap 30, and an adjustment device 40. One end of the first strap 20 and the second strap 30 are respectively connected to the device body 10, and the other end of the first strap 20 and the second strap 30 are respectively connected to the adjustment device 40.

[0039] like Figure 2 As shown, the adjustment device 40 may include: a first housing 450, a dial 490, a central shaft 430, and a locking mechanism; the central shaft 430 may include a first end and a second end disposed opposite to each other, the first end being connected to the dial 490, and the second end being connected to the first strap 20 and the second strap 30, at least a portion of the central shaft 430 extending into the first housing 450; the locking mechanism is disposed in the first housing 450 and movably connected to the dial 490, the dial 490 having an adjustment state and a locking state; wherein, when the dial 490 is in the adjustment state, the dial 490 can rotate relative to the locking mechanism, driving the central shaft 430 to rotate, so as to adjust the tightness between the first strap 20 and the second strap 30; when the dial 490 is in the locking state, the locking mechanism abuts against the dial 490 to restrict the rotation of the dial 490.

[0040] In this embodiment, the wearable device may include a device body 10, a first strap 20, a second strap 30, and an adjustment device 40. One end of the first strap 20 and the second strap 30 are respectively connected to the device body 10, and the other end of the first strap 20 and the second strap 30 are respectively connected to the adjustment device 40. The adjustment device 40 may include a first housing 450, a dial 490, a central shaft 430, and a locking mechanism. When the dial 490 is in the adjustment state, the dial 490 rotates relative to the locking mechanism, driving the central shaft 430 to rotate, thereby adjusting the tightness between the first strap 20 and the second strap 30. When the dial 490 is in the locked state, the locking mechanism abuts against the dial 490 to restrict the rotation of the dial 490, so that the first strap 20 and the second strap 30 can be kept in the adjusted position, preventing the first strap 20 and the second strap 30 from loosening and shaking, thereby improving the user's wearing experience of the wearable device.

[0041] Specifically, the device body 10 can be the main structure of a wearable device. For example, in the case of smart glasses, the device body 10 may include a frame, lenses, and a control system that can be worn outside the user's eyes and perform its main functions. One end of the first strap 20 and the second strap 30 is connected to the device body 10, and the other end of the first strap 20 and the second strap 30 are respectively connected to the adjustment device 40 so that the tightness of the first strap 20 and the second strap 30 can be adjusted by the adjustment device 40.

[0042] like Figure 1 As shown, the device body 10 has a first strap connection structure 101 and a second strap connection structure 102 at both ends. The first strap connection structure 101 can be used to connect to one end of the first strap 20, and the second strap connection structure 102 can be used to connect to one end of the second strap 30. The first strap connection structure 101 and the second strap connection structure 102 can include at least one of buckles, wrap buckles, and magnetic buckles. In this embodiment, the specific form of the first strap connection structure 101 and the second strap connection structure 102 is not limited.

[0043] Optionally, the adjusting device can further comprise a first elastic member 440 connected with the central shaft 430; wherein, when the dial 490 is in the adjusting state, the rotation of the central shaft 430 can drive the first elastic member 440 to rotate, so that the first elastic member 440 can accumulate a certain torsion. When the dial 490 is in the locking state, under the action of the torsion accumulated by the first elastic member 440, the first elastic member 440 can drive the locking mechanism to abut against the dial 490 through the central shaft 430, so as to limit the rotation of the dial 490. Under the action of the torsion of the first elastic member 440, the locking mechanism can be reliably kept in the state of abutting against the dial 490, avoiding the loosening and shaking of the first strap 20 and the second strap 30.

[0044] In some optional embodiments of the present application, the adjusting device 40 can further comprise a gear 420 fixedly connected to the second end of the central shaft 430, and the outer side wall of the gear 420 is provided with meshing teeth; the first strap 20 is provided with a first rack 201, and the second strap 30 is provided with a second rack 301, and the meshing teeth of the gear 420 are respectively engaged with the first rack 201 and the second rack 301. The user can rotate the dial 490 to drive the central shaft 430 to rotate, so as to drive the gear 420 to rotate through the rotation of the central shaft 430. When the dial 490 drives the gear 420 to rotate, the first rack 201 and the second rack 301 can be driven to move relatively close to each other or move away from each other, so as to adjust the tightness of the first strap 20 and the second strap 30.

[0045] In specific applications, the first rack 101 can be engaged at the top of the gear 420, and the second rack 301 can be engaged at the bottom of the gear 420, so that, during the rotation of the gear 420 in the first direction, the first rack 101 and the second rack 301 can be driven to move close to each other, so as to tighten the first strap 20 and the second strap 30; during the rotation of the gear 420 in the second direction, the first rack 201 and the second rack 301 can be driven to move away from each other, so as to loosen the first strap 20 and the second strap 30.

[0046] As Figure 2As shown, the other end of the first strap 20 has an opening, and a first rack 201 is provided at the lower edge of the opening. The first rack 201 meshes with the teeth on the gear 420, causing the first strap 20 to move and adjust its tension. The other end of the second strap 30 has an opening, and a second rack 301 is provided at the upper edge of the opening. The second rack 301 meshes with the teeth on the gear 420, causing the second strap 30 to move and adjust its tension. When the dial 490 is rotated clockwise, the gear 420, through the first rack 201 and the second rack 301, respectively drives the first strap 20 to move to the left and the second strap 30 to move to the right. That is, the first strap 20 and the second strap 30 move away from each other, thereby loosening the first strap 20 and the second strap 30. Alternatively, when the dial 490 is rotated counterclockwise, the gear 420 drives the first strap 20 to move to the right and the second strap 30 to move to the left via the first rack 201 and the second rack 301, respectively. That is, the first strap 20 and the second strap 30 move closer to each other to tighten the first strap 20 and the second strap 30.

[0047] Optionally, the first elastic element 440 is a coil spring, which may specifically include an annular coil spring body. The inner side of the coil spring body has a first end, and the outer side of the coil spring body has a second end. The gear 420 has an annular inner cavity, and the coil spring body is disposed within this cavity and sleeved around the central shaft 430. The first end of the coil spring body is connected to the central shaft 430, and the second end of the coil spring body is connected to the sidewall of the inner cavity of the gear 420. Thus, when the dial 490 is in the adjustment state, the rotation of the dial 490 can drive the central shaft 430 to rotate, and the rotation of the central shaft 430 can drive the coil spring to rotate, allowing the coil spring to accumulate torque. When the dial 490 is in the locked state, the torque of the coil spring can act on the central shaft 430, allowing the locking mechanism to abut against the dial 490, thereby restricting the rotation of the dial 490.

[0048] In practical applications, by placing the coil spring inside the gear 420, it is possible to avoid setting up additional space to place the coil spring, which is conducive to the compact layout of the adjustment device 40 and reduces the size of the adjustment device 40.

[0049] It should be noted that the first elastic element 440 can also be a torsion spring, spring or other elastic element. The specific content of the first elastic element 440 is not limited in the embodiments of this application.

[0050] like Figure 3 As shown, a flange 453 is also provided on the side of the first housing 450 near the coil spring. The flange 453 can be used to limit the movement of the coil spring and improve the installation stability of the coil spring on the central shaft 430.

[0051] like Figure 2As shown, the wearable device can further include a second housing 410, the second housing 410 is connected with the first housing 450, and the first strap 20, the second strap 30 and the locking mechanism are connected to the second housing 410. The second housing 410 can be used to support the first housing 450, the first strap 20, the second strap 30 and the locking mechanism.

[0052] In some optional embodiments of the present application, the dial 490 or the first housing 450 is provided with a ratchet tooth 491, and the locking mechanism can include a pawl 460; the pawl 460 is movably connected with the ratchet tooth 491, in the case that the dial 490 is in the adjusting state, the ratchet tooth 491 rotates relative to the pawl 460; in the case that the dial 490 is in the locking state, the pawl 460 abuts against the ratchet tooth 491 to limit the rotation of the dial 490. In actual application, since the pawl 460 can reliably abut against the ratchet tooth 491, the locking mechanism can reliably limit the rotation of the dial 490, so that the first strap 20 and the second strap 30 can reliably maintain the adjusted length, avoiding the first strap 20 and the second strap 30 from loosening.

[0053] Referring to Figure 4 , a structure schematic view of the dial in the wearable device in the adjusting state or the locking state is shown Figure 1 , a structure schematic view of the dial in the wearable device in the unlocking state is shown. As Figure 5 , Figure 1 , a structure schematic view of the dial in the wearable device in the unlocking state is shown. As Figure 4 , Figure 5 As shown, the locking mechanism can further include a second elastic member 470 and an operating member 480, and the dial 490 further has an unlocking state; wherein the pawl 460 is movably connected with the ratchet tooth 491; the second elastic member 470 is connected with the pawl 460; and the operating member 480 abuts against the pawl 460. Figure 4 As shown, in the case that the dial 490 is in the adjusting state or the locking state, the pawl 460 abuts against the ratchet tooth 491 under the elastic force of the second elastic member 470. In the case that the dial 490 is in the unlocking state, the pawl 460 is separated from the ratchet tooth 491 under the pressing of the operating member 480, and the first strap 20 and the second strap 30 are loosened under the elastic restoring force of the first elastic member 440. Figure 5 As shown, in the case that the dial 490 is in the adjusting state or the locking state, the pawl 460 abuts against the ratchet tooth 491 under the elastic force of the second elastic member 470. In the case that the dial 490 is in the unlocking state, the pawl 460 is separated from the ratchet tooth 491 under the pressing of the operating member 480, and the first strap 20 and the second strap 30 are loosened under the elastic restoring force of the first elastic member 440.

[0054] For example, the second elastic member 470 can include but is not limited to at least one of a spring and a spring sheet, and the embodiments of the present application can not limit the specific content of the second elastic member 470.

[0055] In Figure 1The wearable device shown, the pawl 460 is rotationally connected to the first shell 450, the ratchet teeth 491 are arranged on the dial 490, one end of the second elastic member 470 is connected with the pawl 460, and the other end is connected to the first shell 450; one end of the operating member 480 abuts against the pawl 460, and the other end extends out of the first shell 450. In actual application, by connecting the pawl 460 on the first shell 450, and extending the other end of the operating member 480 through the first shell 450 and out of the first shell 450, the movement of the operating member 480 and the rotation of the dial 490 can be made not to interfere with each other. In this way, in the case that the dial 490 needs to be switched to the adjustment state or the locking state, no operation is needed to be performed on the operating member 480, and in the case that the dial 490 needs to be switched to the unlocking state, the operating member 480 only needs to be pressed, which is extremely convenient and efficient.

[0056] Optionally, the first shell 450 is provided with a first rotation shaft 451 and a first guide groove 452 on the side close to the dial 490, one end of the pawl 460 is sleeved outside the first rotation shaft 451 and can rotate around the first rotation shaft 451, and the other end of the pawl 460 is movably connected with the ratchet teeth 491; the second elastic member 470 is embedded in the first guide groove 452 and can slide along the first guide groove 452. In actual application, by rotating the pawl 460 around the first rotation shaft 451, the relative rotation between the pawl 460 and the ratchet teeth 491 can be realized. By sliding the second elastic member 470 along the first guide groove 452, the pawl 460 and the ratchet teeth 491 can be abutted or disengaged, so as to realize the switching between different states of the dial 490.

[0057] The working example of the wearable device shown is given below. Figure 1 The working example of the wearable device shown is given below.

[0058] The wearing device process is as follows: Figure 4 As shown, when wearing the wearable device, the user rotates the dial 490 counterclockwise, the sliding surface 4911 on the ratchet teeth 491 pushes the pawl 460 to the left and downward, the pawl 460 slides on the sliding surface 4911 under the pushing of the second elastic member 470, the dial 490 drives the gear 420 to rotate counterclockwise through the central shaft 430, and the second band 30 is driven to move leftward through the tooth engagement, and the second band 30 is driven to move rightward to tighten the band, so that the band is tightened to a proper size and tightness adjustment state for the user to use. The movement of the band in this process is as shown in Figure 6 In this process, one end of the first elastic member 440 moves counterclockwise under the driving of the central shaft 430, and a certain clockwise torsion is accumulated in the first elastic member 440 (as shown in Figure 7

[0059] ​Locking Process: After the user adjusts the first strap 20 and the second strap 30 to a suitable tightness, they release the dial 490. At this time, the pawl 460 swings upward under the action of the second elastic element 470, pressing against the ratchet tooth 491. Simultaneously, the clockwise torque accumulated by the first elastic element 440 causes the dial 490 to rotate slightly clockwise, thus locking the pawl 460 against the locking surface 4912 of the ratchet tooth 491. The clockwise rotation of the dial 490 is locked, thereby preventing the first strap 20 and the second strap 30 from loosening and affecting use after prolonged wear. Specifically... Figure 6 As shown above, the torque of the second elastic element 470 prevents slight wobble of the ratchet pawl 460 after locking, thus improving the user experience.

[0060] Equipment removal process: When the user needs to remove the equipment, press down on the operating part 480 to push the pawl 460 out of engagement with the ratchet tooth 491, as shown. Figure 8 As shown. At this time, the central shaft 430 rotates clockwise under the clockwise torque of the first elastic element 440, causing the second strap 30 to move to the right and the first strap 20 to move to the left, thereby easily loosening the first strap 20 and the second strap 30, and removing the equipment. The specific movement is as follows. Figure 8 As shown.

[0061] Reference Figures 9 to 19 This diagram illustrates the structure of another wearable device according to an embodiment of this application. Figures 1 to 8 The difference in the wearable devices shown is that, Figures 9 to 19 In the wearable device shown, a pawl 460 is rotatably connected to a dial 490, ratchet teeth 491 are disposed on the first housing 450, one end of the second elastic member 470 is connected to the pawl 460, and the other end is connected to the dial 490; one end of the operating member 480 abuts against the pawl 460, and the other end extends out of the dial 490. Since the rotation of the dial 490 affects the movement of the operating member 480, when the dial 490 needs to be switched to the unlocked state, the dial 490 needs to be rotated while the operating member 480 is pressed to prevent the operating member 480 from rising under the elastic force of the second elastic member 470, making the operation relatively complicated.

[0062] Optionally, the dial 490 is provided with a second rotating shaft 492 and a second guide slot near one side of the first shell 450, one end of the pawl 460 is sleeved outside the second rotating shaft 492 and can rotate around the second rotating shaft 492, and the other end of the pawl 460 is movably connected with the ratchet teeth 491; the second elastic member 470 is embedded in the second guide slot and can slide along the second guide slot 493. In actual application, the relative rotation between the pawl 460 and the ratchet teeth 491 can be realized through the rotation of the pawl 460 around the second rotating shaft 492. The pawl 460 and the ratchet teeth 491 can be brought into abutment or out of abutment through the sliding of the second elastic member 470 along the second guide slot 493, so as to realize the switching between different states of the dial 490.

[0063] As shown in Figure 14 , the operating member 480 is further provided with a guide column 481, and the dial 490 is further provided with a guide rail 494, the guide column 481 can be embedded in the guide rail 494 and can slide along the guide rail 494, so as to realize the pressing and rising of the operating member 480. In actual application, the guide rail 494 can be used for guiding the movement of the operating member 480, so as to improve the movement accuracy of the operating member 480.

[0064] The working example of the wearable device shown in Figure 9 is given below.

[0065] Wearing device process: as shown in Figure 11 , when wearing the device, the user rotates the dial 490 counterclockwise, the second rotating shaft 492 on the dial 490 drives the pawl 460 to rotate counterclockwise, the sliding surface 4911 on the ratchet teeth 491 pushes the pawl 460 to the left and downward, the pawl 460 slides on the sliding surface 4911 under the pushing of the second elastic member 470, the dial 490 drives the gear 420 to rotate counterclockwise through the central shaft 430, and the second strap 30 is driven to move left and the first strap 20 is driven to move right through the tooth engagement, so as to tighten the strap, make the strap tight to the appropriate size and tightness adjustment state, and provide the user with the strap, the movement of the strap in this process is as shown in Figure 6 . In this process, one end of the first elastic member 440 moves counterclockwise under the driving of the central shaft 430, and a certain clockwise torsion is accumulated in the first elastic member 440 (as shown in Figure 7 ).

[0066] Locking Process: After the user adjusts the strap to a suitable tightness, they release the dial 490. At this time, the pawl 460 swings upward under the action of the second elastic element 470, pressing against the ratchet tooth 491. Simultaneously, the clockwise torque accumulated by the first elastic element 440 causes the dial 490 and pawl 460 to rotate slightly clockwise, thus locking the pawl 460 against the locking surface 4912 of the ratchet tooth 491. The clockwise rotation of the dial 490 is locked, preventing the strap from loosening and affecting usability after prolonged wear. Specifically... Figure 11 As shown above, the torque of the first elastic element 440 prevents slight wobble of the ratchet pawl 460 after locking, thus improving the user experience.

[0067] Equipment removal process: When the user needs to remove the equipment, press down on the operating part 480 to push the pawl 460 out of engagement with the ratchet tooth 491, as shown. Figure 12 As shown. At this time, the central shaft 430 rotates clockwise under the clockwise torque of the first elastic element 440 of the coil spring, driving the second strap 30 to move to the right and the first strap 20 to move to the left, thereby easily rotating the knob to loosen the straps and remove the equipment. The specific movement is as follows: Figure 8 As shown.

[0068] In this solution, removing the device requires pressing the operating element 480 and simultaneously rotating the dial 490, making the operation more complex than the aforementioned implementation scheme. Further, the interaction can be optimized as shown in the diagram below, allowing the user to press the operating element 480 and then push it to lock, thus enabling the wearable device to automatically release under the action of the first elastic element 440. The structures of the operating element 480 and the dial 490 are as follows: Figure 14 and Figure 15 As shown, the operating component 480 is provided with a guide post 481, and the dial 490 is provided with a guide rail 494.

[0069] like Figure 17 As shown, after pressing the operating element 480, the pawl 460 separates from the ratchet tooth 491 and pushes the operating element 480 counterclockwise. At this time, the dial wheel 490 rotates clockwise under the action of the first elastic element 440. Under the action of the thrust and the torque of the first elastic element 440, the guide post 481 is locked into the transverse locking part of the guide rail 494. Here, the operating element 480 is locked on the dial wheel 490, keeping the pawl 460 in a disengaged state. After releasing the operating element 480, the dial wheel 490 automatically rotates clockwise under the action of the first elastic element 440, causing the strap to loosen, making disassembly easier for the user. During the locking / wearing process, it is only necessary to move the button away from the transverse locking part. Its movement process is the same as in the above embodiment and will not be described again.

[0070] In summary, the wearable device according to the embodiments of this application may include at least the following advantages:

[0071] In the embodiments of the present application, the wearable device can include a device body, a first strap, a second strap and an adjusting device, one end of the first strap and the second strap is connected with the device body respectively, the other end of the first strap and the second strap is connected with the adjusting device respectively, the adjusting device can include a first shell, a dial, a center shaft and a locking mechanism. In the case that the dial is in the adjusting state, the center shaft is driven to rotate, the dial rotates relative to the locking mechanism to adjust the tightness between the first strap and the second strap. In the case that the dial is in the locking state, the locking mechanism abuts against the dial to limit the rotation of the dial, so that the first strap and the second strap can be kept in the adjusted position, avoiding the phenomenon of loosening and shaking of the first strap and the second strap, to improve the wearing experience of the user for the wearable device.
