[0033] The following is in conjunction with the accompanying drawings. Figures 1 to 13 The wearable device 100 provided in the embodiments of the present invention will be described in detail through specific implementation methods and application scenarios.

[0034] like Figures 1 to 3 As shown, the wearable device 100 according to an embodiment of the present invention includes a wearable part 10, an adjustment component 20, and a functional component 40.

[0035] Specifically, the wearable part 10 has a wearable space 11, and the adjustment component 20 is connected to the wearable part 10. The adjustment component 20 includes a first bracket 21 and a gear structure 22. The first bracket 21 has a rack structure 211 that extends along a first direction. The gear structure 22 meshes with the rack structure 211. The functional component 40 is connected to the gear structure 22. When the gear structure 22 rotates, it moves relative to the rack structure 211 along the first direction, thereby driving the functional component 40 to move along the first direction.

[0036] In other words, see Figures 1 to 3 The wearable device 100 according to an embodiment of the present invention mainly comprises a wearable part 10, an adjustment component 20, and a functional component 40. The wearable part 10 has a wearing space 11 for wearing on a human head 50, and the wearable part 10 is worn on the human head 50 (see...). Figure 13In the following description of the embodiments of the present invention, when the wearable part 10 is worn, the portion of the wearable part 10 located approximately at the forehead can be understood as the front part of the wearable part 10, and the portion located approximately at the back of the head can be understood as the rear part of the wearable part 10.

[0037] The adjustment component 20 is connected to the wearable part 10, and the adjustment component 20 is generally located at the front of the wearable part 10. For example... Figure 2 As shown, the adjustment component 20 mainly consists of a first support 21 and a gear structure 22. The first support 21 has a rack structure 211, which extends approximately along a first direction. The gear structure 22 meshes with the rack structure 211. The functional component 40 is connected to the gear structure 22 and has a display screen suitable for human viewing. When the user wears the wearable part 10, the user can rotate the gear structure 22 to drive it to move relative to the rack structure 211 along the first direction, thereby moving the functional component 40 along the first direction. This achieves the adjustment of the position of the functional component 40 relative to the user's glasses, ensuring that the center of the screen of the functional component 40 is aligned with the center of the user's pupil, meeting the user's needs and improving the user experience. This invention uses the rotation of the gear structure 22 to adjust the position of the functional component 40. The structure is simple, easy to use, and has a high degree of freedom, allowing users to freely adjust it according to their needs.

[0038] It should be noted that the wearable device 100 of the present invention can be an AR (Augmented Reality) / VR (Virtual Reality) device (e.g., AR / VR glasses). In the following embodiments of the present invention, AR / VR glasses can be used as an example for illustration.

[0039] Therefore, in this embodiment of the invention, an adjustment component 20 is provided on the wearable part 10. The functional component 40 is connected to the gear structure 22 via the first bracket 21 and the gear structure 22 within the adjustment component 20. By rotating the gear structure 22, the gear structure 22 is driven to move relative to the rack structure 211 in the first bracket 21 in a first direction, thereby moving the functional component 40 in the first direction. This achieves adjustment of the position of the functional component 40 relative to the user's glasses, meeting the user's needs. This invention uses the rotating gear structure 22 to adjust the position of the functional component 40, resulting in a simple structure, convenient use, high degree of freedom, and easy adjustment by the user according to their needs.

[0040] According to one embodiment of the present invention, the functional component 40 has a housing 41, a first bracket 21 located between the wearable part 10 and the housing 41, a mounting hole 411 provided on one side of the housing 41, a gear structure 22 rotatably disposed in the mounting hole 411, and gear teeth 223 of the gear structure 22 located outside the mounting hole 411 to mesh with the rack structure 211. When the gear structure 22 moves relative to the rack structure 211 in a first direction, the gear structure 22 drives the functional component 40 to move in the first direction via the housing 41.

[0041] In other words, see Figure 1 and Figure 2 The functional component 40 has a housing 41, which can be integrated onto the functional component 40 to form a whole. The housing 41 can be an independent structure, a part of the functional component 40, and can be fixedly connected to the functional component 40 or detachably connected in other ways.

[0042] The first bracket 21 is disposed between the wearable part 10 and the housing 41. A mounting hole 411 is provided on one side of the housing 41. A gear structure 22 is rotatably disposed within the mounting hole 411. The gear teeth 223 of the gear structure 22 are located outside the mounting hole 411 and can mesh with the rack structure 211. The functional component 40 is hung on the wearable part 10 via the gear structure 22. After the user wears the wearable part 10, by rotating the gear structure 22, the gear structure 22 moves relative to the rack structure 211 along a first direction. At this time, the gear structure 22 can drive the functional component 40 to move along the first direction via the housing 41. It should be noted that the first direction can be roughly understood as the up-and-down direction. Of course, the first direction is not necessarily a completely vertical up-and-down direction. Those skilled in the art should understand that the front of the wearable part 10 and the housing 41 can be configured as an arc shape to fit the human head 50. The first direction is a roughly up-and-down movement along the arc, and its overall movement position is up-and-down. This will not be described in detail in this invention.

[0043] According to one embodiment of the present invention, the adjustment assembly 20 further includes an adjustment rod 23, which is connected to the functional assembly 40. Rotating or moving the adjustment rod 23 causes the functional assembly 40 to move along a second direction.

[0044] In other words, see Figure 2 , Figure 7 and Figure 9The adjustment component 20 may further include an adjustment rod 23, which can be connected to the functional component 40. After the user wears the wearable part 10, the functional component 40 can be moved along a second direction by rotating or moving the adjustment rod 23. The second direction is different from the first direction and can be understood as the length direction or the front-back direction of the adjustment rod 23, thereby realizing the front-back adjustment of the functional component 40. This invention enables the functional component 40 to be adjusted in two different directions—up and down and front and back—through the adjustment component 20 (see movement direction for details). Figure 8 (in the direction of the middle arrow), further increasing the degree of freedom of the user's glasses relative to the screen position of the functional component 40, and better meeting the user's usage needs.

[0045] According to one embodiment of the present invention, the adjusting assembly 20 further includes an adjusting rod 23, the gear structure 22 has a through hole, the adjusting rod 23 passes through the through hole, the gear structure 22 and the adjusting rod 23 are rotatably sleeved, the outer side of the adjusting rod 23 is provided with a first limiting structure 231, and the inner side of the through hole is provided with a second limiting structure 221. During the rotation or movement along the second direction, the adjusting rod 23, through the cooperation of the first limiting structure 231 and the second limiting structure 221, drives the gear structure 22 to move along the second direction.

[0046] In other words, such as Figure 2 , Figure 7 and Figure 9 As shown, the adjustment component 20 may further include an adjustment rod 23. The gear structure 22 has a through hole, through which the adjustment rod 23 can pass, allowing the gear structure 22 and the adjustment rod 23 to be rotatably fitted together. A first limiting structure 231 may be provided on the outer side of the adjustment rod 23, and a second limiting structure 221 may be provided on the inner side of the through hole. When the user wears the wearable device 100, the adjustment rod 23 rests against the forehead of the head through the front part of the wearable part 10. At this time, when the user rotates the adjustment rod 23, the adjustment rod 23 can rotate or move in the second direction. During this process, the first limiting structure 231 on the adjustment rod 23 cooperates with the second limiting structure 221 in the gear structure 22, which can drive the gear structure 22 to move in the second direction, thereby realizing the position adjustment of the functional component 40 in the second direction.

[0047] In this invention, see Figure 7 and Figure 9The first limiting structure 231 can be configured as an external thread structure on the outer circumference of the adjusting rod 23, and the second limiting structure 221 can be configured as an internal thread structure extending inside the through hole of the gear structure 22. The external thread structure and the internal thread structure are threadedly engaged. When the adjusting rod 23 is rotated, since the wearable device 100 is worn on the head, one end of the adjusting rod 23 is pressed against the head. At this time, the gear structure 22 and the adjusting rod 23 form a screw-like structure, causing the gear structure 22 to move along the axial direction of the adjusting rod 23, that is, along the length direction of the adjusting rod 23, thereby driving the functional component 40 to move along the axial direction of the adjusting rod 23, realizing the back-and-forth adjustment of the position of the functional component 40 and the human eye. It should be noted that the axial direction of the adjusting rod 23 is the second direction.

[0048] Of course, the first limiting structure 231 can also be a protrusion on the outer circumference of the adjusting rod 23, and the second receiving structure can also be a groove within the gear structure 22. Through the cooperation of the protrusion and the groove, the gear structure 22 can move relative to the adjusting rod 23, thereby achieving the adjustment of the front and rear position of the functional component 40. This invention does not limit the specific structure of the first limiting structure 231 and the second limiting structure 221. Any structural design that allows relative movement between the gear structure 22 and the adjusting rod 23 should fall within the protection scope of this invention.

[0049] According to one embodiment of the present invention, the adjustment assembly 20 further includes a second knob 25, which is sleeved on the adjustment rod 23. The first limiting structure 231 and the second limiting structure 221 are threadedly engaged. Rotating the second knob 25 drives the adjustment rod 23 to rotate, thereby driving the gear structure 22 to move along the second direction.

[0050] In other words, such as Figures 7 to 9 As shown, the adjustment component 20 may also include a second knob 25, which can be sleeved on the adjustment rod 23. The first limiting structure 231 and the second limiting structure 221 can be designed as a threaded engagement structure. After the user puts on the wearable part 10, since the wearable device 100 is worn on the head, one end of the adjustment rod 23 is pressed against the head. At this time, by rotating the second knob 25, the adjustment rod 23 can be rotated, thereby driving the gear structure 22 to move in the second direction, realizing the forward and backward movement of the functional component 40.

[0051] In this invention, the part of the adjusting rod 23 corresponding to the second knob 25 can be designed as an incomplete circle. That is to say, this part of the adjusting rod 23 does not have to be a complete cylindrical rod. The design of the incomplete circle makes it easier to rotate the adjusting rod 23 when the second knob 25 is turned, thereby driving the gear structure 22 to move in the second direction.

[0052] According to one embodiment of the present invention, the adjusting assembly 20 further includes a first knob 24, which is disposed outside the gear structure 22. Rotating the first knob 24 drives the gear structure 22 to rotate, thereby driving the functional assembly 40 to move along a first direction through the engagement of the gear structure 22 and the rack structure 211. The gear structure 22 is disposed at one end of the adjusting rod 23, and a second knob 25 is disposed at the other end of the adjusting rod 23. The second knob 25 and the first knob 24 are rotatably connected to each other to limit the relative movement of the second knob 25 and the first knob 24 in a second direction.

[0053] In other words, see Figure 2 , Figure 7 and Figure 9 The adjusting component 20 may further include a first knob 24, which may be located on the outside of the gear structure 22. Rotating the first knob 24 drives the gear structure 22 to rotate. Simultaneously, through the engagement of the gear structure 22 and the rack structure 211, the functional component 40 can be moved along a first direction, achieving vertical adjustment of the functional component 40. The gear structure 22 is located at one end of the adjusting rod 23, and the second knob 25 is located at the other end of the adjusting rod 23. The second knob 25 and the first knob 24 are rotatably connected to each other, thereby limiting the relative movement of the second knob 25 and the first knob 24 in a second direction. This invention, by providing an adjusting rod 23, can share the engagement with the first knob 24 and the second knob 25 to achieve vertical and horizontal movement of the functional component 40, effectively saving space and simplifying operation.

[0054] After the user puts on the wearable device 10, see Figure 7 and Figure 9 When the position of the functional component 40 needs to be adjusted, the user can rotate the first knob 24, which drives the gear structure 22 to rotate relative to the rack structure 211 on the first bracket 21, causing the functional component 40 to move vertically. Simultaneously, rotating the second knob 25 drives the adjusting rod 23 to rotate, allowing the gear structure 22 to move relative to the adjusting rod 23 along its length, thus achieving coarse adjustment of the functional component 40 in both vertical and longitudinal directions. The coarse adjustment primarily involves adjusting the vertical position of the functional component 40. After coarse adjustment, rotating the second knob 25 alone drives the adjusting rod 23 to rotate, causing the gear structure 22 to move axially relative to the adjusting rod 23, thereby achieving fine adjustment of the functional component 40 in the longitudinal direction, ensuring that the wearable device 100 meets the user's needs.

[0055] In this invention, in order to facilitate the second knob 25 to drive the adjusting rod 23 to rotate, a limiting protrusion 413 or other limiting mechanism can be provided on the outer peripheral surface of the portion of the adjusting rod 23 located on the second knob 25. A limiting groove that cooperates with the limiting protrusion 413 can be provided in the second knob 25, so that when the user rotates the second knob 25, the adjusting rod 23 is driven to rotate by the second knob 25, thereby realizing that the gear structure 22 drives the functional component 40 to move in the front and back direction.

[0056] In some specific embodiments of the present invention, the adjusting assembly 20 further includes a second retaining spring 27. One end of the first knob 24 is provided with a first limiting recess, and the end of the second knob 25 extends into the first limiting recess. The side wall of the first limiting recess is provided with a first limiting groove 241, and the second knob 25 is provided with a second limiting groove 251. When the end of the second knob 25 extends into the first limiting recess, the first limiting groove 241 and the second limiting groove 251 form a first limiting cavity. The second retaining spring 27 is provided in the first limiting cavity to restrict the relative movement of the second knob 25 and the first knob 24 in the second direction.

[0057] In other words, see Figure 2 , Figure 7 and Figure 9 The adjustment assembly 20 may further include a second retaining spring 27. One end of the first knob 24 may be provided with a first limiting recess, and the end of the second knob 25 may extend into the first limiting recess. The side wall of the first limiting recess is provided with a first limiting groove 241, and the second knob 25 is provided with a second limiting groove 251 corresponding to the first limiting groove 241. When the end of the second knob 25 extends into the first limiting recess, the first limiting groove 241 and the second limiting groove 251 form a first limiting cavity. The second retaining spring 27 is disposed in the first limiting cavity. The second retaining spring 27 can restrict the relative movement of the second knob 25 and the first knob 24 in the front-back direction, making it convenient for the user to rotate the first knob 24 and the second knob 25 to adjust in the up-down and front-back directions. At the same time, the first knob 24 and the second knob 25 are connected and limited to each other through the second retaining spring 27, which can restrict the relative movement of the second knob 24 and the first knob 25 in the front-back direction while ensuring that the overall appearance of the wearable device 100 is more aesthetically pleasing.

[0058] According to one embodiment of the present invention, the adjusting assembly 20 further includes a second bracket 31, which is connected to the first bracket 21, and a first cavity 32 is formed between the first bracket 21 and the second bracket 31. The adjusting assembly 20 also includes a first limiting member 33, and a guide recess 232 is provided on the end face of the adjusting rod 23. One end of the first limiting member 33 is located in the first cavity 32, and the other end of the first limiting member 33 is movably inserted into the guide recess 232 of the adjusting rod 23. When the adjusting rod 23 is rotated, the first limiting member 33 restricts the movement of the adjusting rod 23 in the second direction, so that the gear structure 22 moves in the second direction.

[0059] In other words, see Figure 2 , Figure 7 and Figure 9 The adjustment component 20 may also include a second support 31, which is connected to the first support 21. When the wearable device 100 is worn, the second support 31 can fit snugly against the forehead. A first cavity 32 is formed between the first support 21 and the second support 31. The adjustment component 20 may also include a first limiting member 33. A guide recess 232 may be provided on the end face of the adjustment rod 23 facing the second support 31. One end of the first limiting member 33 is located in the first cavity 32, and the other end of the first limiting member 33 is movably inserted into the guide recess 232 of the adjustment rod 23. When the user wears the wearable part 10, the user can rotate the adjustment rod 23. The adjustment rod 23 abuts against the forehead through the first limiting member 33 and the second support 31. At this time, the first limiting member 33 restricts the movement of the adjustment rod 23 in the second direction, thereby causing the gear structure 22 to move in the second direction, which in turn drives the functional component 40 to move in the second direction (front-back direction), thereby realizing the front-back position adjustment of the functional component 40.

[0060] In this invention, such as Figure 2 , Figure 7 and Figure 9 As shown, the adjustment assembly 20 may further include a third bracket 34, which is disposed between the first bracket 21 and the second bracket 31 and is connected to the first bracket 21. The second bracket 31 can be connected to the first bracket 21 through the third bracket 34. The portion of the third bracket 34 located within the first cavity 32 may have a guide hole 341, which communicates with the first cavity 32 and extends along a first direction.

[0061] See Figure 7 and Figure 9The adjusting assembly 20 may further include a first limiting member 33, which includes a first guide portion 331 and a first flange portion 332 connected to each other. One end of the first guide portion 331 away from the first flange portion 332 extends through the guide through hole 341 into the guide recess 232. The first limiting member 33 can be connected to the gear structure 22 via the adjusting rod 23 and moves along the first direction with the gear structure 22. The first flange portion 332 is sandwiched between the third bracket 34 and the second bracket 31, and the gear structure 22 is limited between the third bracket 34 and the first bracket 21.

[0062] like Figure 9 As shown, during the rotation of the gear structure 22, the first limiting member 33 moves along the guide through hole 341, that is, the first limiting member 33 moves along the first direction with the gear structure 22, and the first guide portion 331 can move along the guide recess 232. Specifically, since the second bracket 31 is designed to match the arc surface of the user's forehead, during the movement of the functional component 40 by the gear structure 22 in the first direction, the first limiting member 33 and the adjusting rod 23 can move relative to each other in the second direction to avoid jamming.

[0063] During the rotation of the adjusting rod 23, the first limiting member 33 restricts the movement of the adjusting rod 23 in the second direction, so that the gear structure 22 moves in the second direction.

[0064] In some specific embodiments of the present invention, see Figure 2 , Figure 7 and Figure 9 The adjustment assembly 20 also includes a first knob 24, one end of which has a second limiting recess. One end of the gear structure 22 is inserted into the second limiting recess, and the other end of the gear structure 22 has teeth 223 on its outer side. The adjustment assembly 20 also includes a first retaining spring 26. The side wall of the second limiting recess has a third limiting groove 242, and one end of the gear structure 22 has a fourth limiting groove 222. When one end of the gear structure 22 extends into the second limiting recess, the third limiting groove 242 and the fourth limiting groove 222 form a second limiting cavity. The second retaining spring 27 is disposed in the second limiting cavity to restrict the relative movement of the gear structure 22 and the first knob 24 in the second direction. Rotating the first knob 24 drives the gear structure 22 to rotate. Through the meshing of the teeth 223 with the rack structure 211, the gear structure 22 moves in the first direction, thereby driving the functional assembly 40 to move in the first direction.

[0065] In other words, see Figure 2 , Figure 7 and Figure 9The adjusting assembly 20 may further include a first knob 24, one end of which may be provided with a second limiting recess, and one end of the gear structure 22 is inserted into the second limiting recess of the first knob 24. The other end of the gear structure 22 has teeth 223 on its outer side, which mesh with the rack structure 211 on the first bracket 21. The adjusting assembly 20 also includes a first retaining spring 26, the sidewall of the second limiting recess may have a third limiting groove 242, and one end of the gear structure 22 has a fourth limiting groove 222. When one end of the gear structure 22 extends into the second limiting recess, the third limiting groove 242 and the fourth limiting groove 222 form a second limiting cavity. A second retaining spring 27 is installed in the second limiting cavity, which restricts the relative movement of the gear structure 22 and the first knob 24 in the axial direction of the adjusting rod 23. After the user puts on the wearable device 10, the first knob 24 can be turned to drive the gear structure 22 to rotate. Through the meshing of the gear teeth 223 with the rack structure 211, the gear structure 22 moves along the rack structure 211 in the first direction, thereby driving the functional component 40 to move in the first direction and realizing the position adjustment of the functional component 40 in the vertical direction.

[0066] According to one embodiment of the present invention, the adjusting assembly 20 further includes a first knob 24 and a self-locking assembly 35. The self-locking assembly 35 is disposed between the first knob 24 and the housing 41 to limit the rotation of the gear structure 22. The housing 41 has a receiving recess 412 on the side facing the first knob 24. The sidewall of the receiving recess 412 is provided with a plurality of limiting protrusions 413. A mounting hole 411 is opened on the bottom surface of the receiving recess 412. One end of the gear structure 22 passes through the mounting hole 411 and is connected to the first knob 24. The first knob 24 is sleeved on the outside of the gear structure 22.

[0067] The self-locking assembly 35 includes a self-locking limiting member 351, which is sleeved on the outside of the gear structure 22 and disposed in the receiving recess 412. The self-locking limiting member 351 has a connecting portion 3551 and at least one self-locking limiting portion. The connecting portion 3551 is connected to the gear structure 22 to limit the relative rotation between the self-locking limiting member 351 and the gear structure 22. When the self-locking assembly 35 is in the self-locking state, the self-locking limiting portion abuts against the limiting protrusion 413 to limit the rotation of the self-locking limiting member 351 relative to the housing 41.

[0068] The first knob 24 has a toggle part on the side facing the housing 41. The toggle part is sandwiched between the self-locking limiting member 351 and the side wall of the receiving recess 412. When the first knob 24 is rotated, the toggle part rotates in the rotation direction of the first knob 24 to push the self-locking limiting member and the limiting protrusion 413 to move relative to each other, thereby switching the adjustment component 20 from the self-locking state to the adjustment state.

[0069] In other words, such as Figure 7 As shown, the adjusting assembly 20 may further include a first knob 24 and a self-locking assembly 35. The self-locking assembly 35 is disposed between the first knob 24 and the housing 41. The self-locking assembly 35 is mainly used to restrict the rotation of the gear structure 22, facilitating the formation of a lead screw-like structure between the gear structure 22 and the adjusting rod 23. See also Figures 10 to 12 The housing 41 has a receiving recess 412 on the side facing the first knob 24. Multiple limiting protrusions 413 are provided on the sidewall of the receiving recess 412, arranged in a ring within the receiving recess 412. A mounting hole 411 is formed on the bottom surface of the receiving recess 412 in the housing 41. One end of the gear structure 22 can pass through the mounting hole 411 and connect to the first knob 24. The first knob 24 is fitted onto the outside of the gear structure 22, driving the gear structure 22 to rotate.

[0070] like Figure 11 As shown, the self-locking assembly 35 includes a self-locking limiting member 351, which is sleeved on the outside of the gear structure 22 and disposed in the receiving recess 412. The self-locking limiting member 351 has a connecting portion 3551 and at least one self-locking limiting portion. The connecting portion 3551 is connected to the gear structure 22 and can restrict the relative rotation between the self-locking limiting member 351 and the gear structure 22. When the self-locking assembly 35 is in the self-locking state, the self-locking limiting portion abuts against the limiting protrusion 413, thereby restricting the rotation of the self-locking limiting member 351 relative to the housing 41. At this time, by rotating the second knob 25, the adjusting rod 23 is rotated. Due to the self-locking of the gear structure 22 by the self-locking assembly 35, the gear structure 22 cannot rotate and moves along the length direction of the adjusting rod 23, thereby driving the functional component 40 to move back and forth.

[0071] The first knob 24 has a toggle part on the side facing the housing 41. The toggle part can be clamped between the self-locking limiting member 351 and the side wall of the receiving recess 412. After the user puts on the wearable part 10, by rotating the first knob 24, the toggle part rotates in the rotation direction of the first knob 24, thereby pushing the self-locking limiting member and the limiting protrusion 413 to move relative to each other, thereby switching the adjustment component 20 from the self-locking state to the adjustment state, ensuring that the gear structure 22 can rotate relative to the rack structure 211 on the first bracket 21, realizing the up and down adjustment of the functional component 40.

[0072] It should be noted that the present invention is mainly described using the case where the wearable part 10 is worn on the user's head as an example. When the wearable part 10 is worn on the head, since the second bracket 31 abuts against the forehead, the adjusting rod 23 is pressed against the forehead by the first limiting member 33 and the second bracket 31. Therefore, when the second knob 25 is rotated, the forward and backward movement of the adjusting rod 23 is restricted, causing the gear structure 22 to move forward and backward relative to the adjusting rod 23, thereby realizing the forward and backward adjustment of the functional component 40.

[0073] When the wearable part 10 is not worn on the human head 50, the adjusting rod 23 can be moved in the second direction relative to the gear structure 22 by rotating the second knob 25 (see...). Figure 8 The distance between the second support 31 and the functional component 40 in the second direction can be adjusted, thereby adjusting the size of the wearing space 11, making it easier for the wearable device 100 to adapt to users with different head sizes, and improving the flexibility and versatility of the wearable device 100 in adjustment.

[0074] In some specific embodiments of the present invention, the self-locking limiting member 351 is deformable, and a deformation gap is left between the self-locking limiting part and the gear structure 22. When the adjusting component 20 is in the self-locking state, the self-locking limiting part abuts against the limiting protrusion 413 to restrict the rotation of the gear structure 22 through the connecting part 3551, thereby restricting the movement of the gear structure 22 relative to the rack structure 211 in the first direction, and further restricting the movement of the functional component 40 in the first direction.

[0075] When the first knob 24 is turned to put the adjustment component 20 into the adjustment state, the first knob 24 drives the gear structure 22 and the self-locking limiting member 351 to rotate. The actuating part rotates with the first knob 24 and squeezes the limiting member to deform, so that the self-locking limiting part can move relative to the limiting protrusion 413.

[0076] In other words, see Figure 11The self-locking limiting member 351 can deform during operation. A deformation gap is left between the self-locking limiting part of the self-locking limiting member 351 and the gear structure 22 to facilitate deformation of the self-locking limiting part and switch between the self-locking and unlocking states. After the user puts on the wearing part 10, when the adjusting component 20 is in the self-locking state, the self-locking limiting part abuts against the limiting protrusion 413. At this time, the connecting part 3551 can restrict the rotation of the gear structure 22, thereby restricting the movement of the gear structure 22 relative to the rack structure 211 in the first direction, and thus restricting the movement of the functional component 40 in the first direction. When the first knob 24 is turned to put the adjustment component 20 into the adjustment state, the first knob 24 can drive the gear structure 22 and the self-locking limiting member 351 to rotate. At this time, the actuating part can rotate with the first knob 24 and squeeze the self-locking limiting member 351 to deform, so that the self-locking limiting part can move relative to the limiting protrusion 413, thereby realizing the movement of the gear structure 22 relative to the rack structure 211 in the first direction.

[0077] According to one embodiment of the present invention, the self-locking limiting member 351 is an annular member with a notch 3552. The self-locking limiting member 351 is provided with a first self-locking limiting portion 3553 and a second self-locking limiting portion 3554, and the notch 3552 is formed between the first self-locking limiting portion 3553 and the second self-locking limiting portion 3554. When the adjusting component 20 is in the self-locking state, the first self-locking limiting portion 3553 and the second self-locking limiting portion 3554 respectively abut against a limiting protrusion 413 to limit the movement. The first self-locking limiting portion 3553 restricts the gear structure 22 to rotate clockwise, and the second self-locking limiting portion 3554 restricts the gear structure 22 to rotate counterclockwise. The first knob 24 has a first actuating part 243 and a second actuating part 244. The first actuating part 243 is located on the side of the first self-locking limiting part 3553 opposite to the notch 3552. The first actuating part 243 is used to release the abutment between the first self-locking limiting part 3553 and a limiting protrusion 413 when the first knob 24 is rotated. The second actuating part 244 is located on the side of the second self-locking limiting part 3554 opposite to the notch 3552. The second actuating part 244 is used to release the abutment between the second self-locking limiting part 3554 and another limiting protrusion 413 when the first knob 24 is rotated.

[0078] In other words, such as Figure 11As shown, the self-locking limiting member 351 can be designed as an annular member with a notch 3552. The self-locking limiting member 351 is provided with a first self-locking limiting part 3553 and a second self-locking limiting part 3554, and the notch 3552 can be located between the first self-locking limiting part 3553 and the second self-locking limiting part 3554. When the adjusting component 20 is in the self-locking state, the first self-locking limiting part 3553 and the second self-locking limiting part 3554 respectively abut against a limiting protrusion 413 to limit the movement. The first self-locking limiting part 3553 can limit the gear structure 22 to rotate clockwise, and the second self-locking limiting part 3554 can limit the gear structure 22 to rotate counterclockwise, thereby ensuring that the gear structure 22 can be self-locked.

[0079] See Figure 11 The first knob 24 has a first actuating part 243 and a second actuating part 244. The first actuating part 243 can be disposed on the side of the first self-locking limiting part 3553 opposite to the notch 3552. The first actuating part 243 is mainly used to release the abutment between the first self-locking limiting part 3553 and a limiting protrusion 413 when the first knob 24 is rotated. The second actuating part 244 can be disposed on the side of the second self-locking limiting part 3554 opposite to the notch 3552. The second actuating part 244 is mainly used to release the abutment between the second self-locking limiting part 3554 and another limiting protrusion 413 when the first knob 24 is rotated, ensuring that the gear structure 22 can move relative to the rack structure 211, thereby realizing the movement of the functional component 40 in the first direction.

[0080] In some specific embodiments of the present invention, such as Figure 2 and Figure 7 As shown, the adjustment assembly 20 may further include a second bracket 31 and a third bracket 34. The third bracket 34 may be disposed between the first bracket 21 and the second bracket 31, and the third bracket 34 is connected to the first bracket 21. The second bracket 31 can be connected to the first bracket 21 through the third bracket 34, forming a first cavity 32 between the first bracket 21 and the second bracket 31. The portion of the third bracket 34 located within the first cavity 32 has a guide hole 341, which communicates with the first cavity 32 and extends along a first direction.

[0081] like Figure 2 and Figure 7As shown, the adjustment assembly 20 may further include a first limiting member 33. The first limiting member 33 includes a first guide portion 331 and a first flange portion 332 connected to each other. The end of the first guide portion 331 away from the first flange portion 332 can pass through the guide hole 341 and connect to the gear structure 22. The first flange portion 332 is sandwiched between the third bracket 34 and the second bracket 31 to limit the position of the adjustment rod 23. After the wearing part 10 is worn, the gear structure 22 moves relative to the adjustment rod 23 in the second direction. During the movement of the gear structure 22 relative to the rack structure 211 in the first direction, the first limiting member 33 moves along the guide hole 341.

[0082] During the rotation of the gear structure 22, the first limiting member 33 moves along the guide through hole 341, that is, the first limiting member 33 moves along the first direction with the gear structure 22, and the first guide portion 331 can move along the guide recess 232. Specifically, since the second bracket 31 is designed to match the arc surface of the user's forehead, during the movement of the gear structure 22 driving the functional component 40 along the first direction, the first limiting member 33 and the adjusting rod 23 can move relative to each other in the second direction to avoid jamming. During the rotation of the adjusting rod 23, the first limiting member 33 restricts the movement of the adjusting rod 23 in the second direction, so that the gear structure 22 moves in the second direction.

[0083] According to one embodiment of the present invention, such as Figure 2 , Figure 3 and Figure 6 As shown, a sliding groove 342 may be provided on the third bracket 34, and the sliding groove 342 may extend along the second direction. The adjusting assembly 20 may also include a second limiting member 36, through which the third bracket 34 can be connected to the first bracket 21. During the rotation of the adjusting rod 23, see... Figure 4 , Figure 5 and Figure 7 The gear structure 22 can drive the first bracket 21 to move in the second direction, while the second limiting member 36 moves along the slide groove 342, so as to realize the movement of the functional component 40 in the second direction.

[0084] Optionally, see Figure 10 The second limiting member 36 includes a second guide portion 361 and a second flange portion 362 connected to each other. One end of the second guide portion 361, away from the second flange portion 362, can pass through the slide groove 342 and connect to the first bracket 21, thereby connecting the first bracket 21 and the third bracket 34. The second flange portion 362 is located outside the slide groove 342 and can restrict the relative movement of the first bracket 21 and the third bracket 34 in the first direction, ensuring the movement of the first bracket 21 and the third bracket 34 in the second direction.

[0085] According to one embodiment of the present invention, such as Figure 13As shown, the functional component 40 includes a display for facing the user's eyes. The angle between the line connecting the user's eyes and the first direction is approximately between 75 degrees and 110 degrees, and the second direction is perpendicular to the first direction, which allows the wearable device 100 to design the specific range of movement of the functional component 40 in the first and second directions according to the actual wearing situation.

[0086] Under normal circumstances, the angle between the first direction and the line connecting the user's eyes is about 90 degrees, so that the adjustment of the functional component 40 in the vertical direction can be completed with the shortest path. This maximizes the adjustment efficiency and reduces the operation time when the user makes coarse and fine adjustments to the position of the functional component 40.

[0087] In this embodiment, the wearable device 100 allows for positional adjustment of the functional component 40 in both a first and second direction via the adjustment component 20. This ensures that the center of the display screen of the functional component 40 remains aligned with the center of the user's pupil after wearing, through vertical adjustment along the first direction. Simultaneously, it ensures that the distance between the display screen and the user's eyes can be adjusted by forward and backward adjustment along the second direction, thereby improving user comfort. Furthermore, during the vertical adjustment of the display screen of the functional component 40 along the first direction, the first support 21 in the adjustment component conforms to the curved surface of the user's forehead, allowing for free adjustment of wearing tilt, force uniformity, and other aspects, further enhancing the user experience.

[0088] It should be noted that, in this application, the up-down direction, i.e., the first direction, refers to the direction from head to feet or from feet to head when the user is standing while wearing the wearable device. The front-back direction, i.e., the second direction, refers to the direction from back to chest or from chest to back when the user is standing while wearing the wearable device.

[0089] Of course, other structures and working principles of the wearable device 100 are understandable and achievable by those skilled in the art, and will not be described in detail in this invention.
