[0046] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0048] like Figures 1 to 6As shown, the present disclosure provides a spacing adjustment structure, which includes a fixed plate 1, an adjustment component 2, a worm 3 and a transmission member 4. Among them, there are two adjustment components 2, and the two adjustment components 2 are slidably arranged on the first side of the fixed plate 1 in the thickness direction and are spaced apart in the first direction; the adjustment component 2 includes a connected adjustment member 21 and a rack 22, the rack 22 extends along the first direction, and the two racks 22 are staggered in the second direction. The worm 3 is arranged on the first side of the fixed plate 1 and extends along the first direction. The transmission member 4 is rotatably arranged on the first side of the fixed plate 1 and is located between the two adjustment members 21. The transmission member 4 has a worm gear set 411 and two transmission gear sets 421. The worm gear set 411 is engaged with the worm 3, and the two transmission gear sets 421 are respectively engaged with the two racks 22; the first direction is perpendicular to the second direction. When the worm 3 rotates, the two racks 22 are driven to move through the transmission member 4 to drive the two adjustment members 21 to move closer to or away from each other in the first direction. Among them, the first direction is as shown in FIG. Figure 1 The ab direction in the second direction is Figure 2 cd direction in .

[0049] It can be understood that by setting the worm 3 and the transmission member 4, the transmission member 4 is engaged with the worm 3 through the worm gear set 411, and is engaged with the two racks 22 respectively through the two transmission gear sets 421. The rotation of the worm 3 is converted into a linear movement of the rack 22 in the first direction through the transmission member 4, which can drive the two adjusting members 21 to move closer to or away from each other in the first direction, thereby realizing the adjustment of the spacing between the two adjusting members 21 in the first direction. Moreover, since the transmission member 4 is located between the two adjusting members 21, the worm 3 extends along the first direction, and can be arranged using the space between the adjusting members 21, thereby reducing the space occupied in the thickness direction of the fixed plate 1, which is conducive to a thinning design.

[0050] Furthermore, the cooperation between the worm 3 and the worm gear set 411 can achieve self-locking when the worm 3 stops rotating, thereby enabling the distance between the two adjusting members 21 to remain stable when the requirement is met.

[0051] For example, in a specific implementation, the adjusting member 21 may be a lens barrel. In this case, the spacing adjustment structure is part of the head-mounted glasses, thereby adjusting the distance between the two lens barrels, that is, the pupil distance. Alternatively, the adjusting member 21 may be another structure that requires spacing adjustment.

[0052] like Figure 1 and Figure 2 As shown, the transmission member 4 includes a first transmission member 41 and a second transmission member 42. One end of the first transmission member 41 is connected to the second transmission member 42, and the other end is provided with a worm gear set 411. The second transmission member 42 is provided with a transmission gear set 421 at both ends of its extension direction.

[0053] Such a configuration can cooperate with the worm 3 and the rack 22 to drive the adjusting member 21. The rotation of the worm 3 drives the first transmission member 41 to rotate, and at the same time drives the second transmission member 42 to rotate. The transmission tooth group 421 of the second transmission member 42 drives the rack 22 to move in the first direction.

[0054] It should be noted that the first transmission member 41 and the second transmission member 42 are integrally provided or separately provided and connected as a whole.

[0055] For example, referring to Figure 2 In a specific implementation, the first transmission member 41 and the second transmission member 42 are both long strip structures. Setting the first transmission member 41 and the second transmission member 42 as long strip structures, that is, the first transmission member 41 is not a complete worm gear, and the second transmission member 42 is not a complete gear, can reduce the space occupied by the transmission member 4, thereby adapting to the space between the two adjustment members 21 in the first direction.

[0056] Furthermore, the diameter of the circle encompassing the worm gear set 411 when the first transmission member 41 rotates is greater than the diameter of the circle encompassing the transmission gear set 421 when the second transmission member 42 rotates. Understandably, the worm gear set 411 of the first transmission member 41 is relatively distant from the second transmission member 42. This allows the length of the first transmission member 41 to be utilized to position the worm 3 away from the adjustment member 21, preventing interference between the movement of the adjustment member 21 and the worm 3.

[0057] Furthermore, the second transmission member 42 is symmetrically designed about its rotation center, that is, the lengths on both sides of the rotation center are the same, so that the second transmission member 42 can drive the two racks 22 to move the same distance on the first square, thereby facilitating the adjustment of the spacing between the two adjustment members 21.

[0058] Further, refer to Figure 2 The extending direction of the first transmission member 41 and the extending direction of the second transmission member 42 form a first preset angle, which is an acute angle. The first preset angle can be set according to actual needs.

[0059] It can be understood that there is an acute angle between the extension directions of the first transmission member 41 and the second transmission member 42, so that within the swing range when the first transmission member 41 cooperates with the worm 3, the engagement range of the second transmission member 42 with the rack 22 is increased when it rotates, thereby increasing the moving distance of the rack 22 in the first direction, and further increasing the adjustment range of the distance between the two adjustment members 21.

[0060] like Figure 1 As shown, a rotating shaft 11 is provided on the fixing plate 1 , and the transmission member 4 can rotate around the rotating shaft 11 ; the rotating shaft 11 is provided at the central symmetry line position of the two adjusting members 21 .

[0061] By arranging the rotating shaft 11 at the central symmetry line of the two adjusting members 21, the yaw torque of the second transmission member 42 on the adjusting member 21 can be reduced when the transmission member 4 rotates, thereby reducing the tendency of the adjusting member 21 to deflect when moving and increasing the flexibility and smoothness of the transmission.

[0062] Specifically, refer to Figure 1 The transmission member 4 is provided with an axial hole, which passes through the first transmission member 41 and the second transmission member 42, and the rotating shaft is provided in the axial hole. In addition, the rotating shaft is provided with a threaded hole, and the transmission member 4 is limited by connecting the bolt with the threaded hole.

[0063] like Figure 1 As shown, in some embodiments, the rack 22 is provided with a sliding groove 221 extending along the first direction;

[0064] The adjustment assembly 2 includes a limiter 23 connected to the adjustment member 21 . The rack 22 and the limiter 23 of the adjustment assembly 2 are spaced apart in the second direction. The limiter 23 of each adjustment assembly 2 extends into the slide groove 221 on the rack 22 of another adjustment assembly 2 .

[0065] It can be understood that the limit member 23 of each adjustment component 2 extends into the slide groove 221 on the rack 22 of the other adjustment component 2, so that when adjusting the spacing between the two adjustment components 21 in the first direction, the limit member 23 is always located in the slide groove 221 of the corresponding rack 22. In this way, the deflection of the rack 22 can be limited by the cooperation between the limit member 23 and the rack 22, thereby limiting the deflection of the adjustment component 21, which is beneficial to improving the smoothness of the transmission between the rack 22 and the second transmission component 42.

[0066] It can be understood that the rack 22 and the limit member 23 of the adjustment component 2 are spaced apart in the second direction, and the two racks 22 of the two adjustment components 2 are staggered in the second direction, that is, the two racks 22 are not on the same straight line, but are arranged in parallel and spaced apart, so that the second transmission member 42 can simultaneously drive the two racks 22 to move in the first direction.

[0067] like Figure 1 As shown, the spacing adjustment structure further includes a guide member 5 , which is disposed on the fixed plate 1 and extends along the first direction. The adjustment assembly 2 is slidably disposed on the guide member 5 .

[0068] By providing the guide member 5 , the movement of the adjustment assembly 2 can be guided, so that the adjustment assembly 2 moves along the first direction, ensuring that the distance between the two adjustment members 21 is adjusted in the first direction.

[0069] For example, in a specific implementation, referring to Figure 1The guide member 5 is disposed on the second side of the fixed plate 1 in the thickness direction. The fixed plate 1 is provided with a through hole 12. The adjustment assembly 2 further includes a mounting member 24. The adjustment member 21 and the rack 22 are both disposed on the mounting member 24. The mounting member 24 has a through portion 241 that penetrates the through hole 12. The through portion 241 is sleeved on the guide member 5.

[0070] It can be understood that arranging the guide member 5 on the second side of the fixed plate 1 can, on the one hand, avoid interference between the guide member 5 and the worm 3 , and on the other hand, prevent the guide member 5 from occupying the space on the first side of the fixed plate 1 .

[0071] For example, in a specific implementation, referring to Figure 1 , two guide members 5 are provided corresponding to each adjustment component 2, and the two guide members 5 are spaced apart in the second direction.

[0072] That is to say, the mounting member 24 and the two guide members 5 are in sliding cooperation, and the two guide members 5 are spaced apart in the second direction, which can further improve the stability of the adjustment assembly 2 during movement.

[0073] In some embodiments, the spacing adjustment structure further includes a driving member, which is disposed on the first side of the fixing plate 1 and is used to drive the worm 3 to rotate.

[0074] For example, in a specific implementation, referring to Figure 1 The driving member may be a motor 6. The output shaft of the motor 6 is connected to the worm 3. In this case, the interpupillary distance can be automatically adjusted without the user having to manually rotate the worm 3. Alternatively, the driving member may be a manually rotatable member connected to the worm 3, such as a hand crank. In this case, the user can manually rotate the worm 3 to adjust the distance between the two adjustment members 21 in the first direction.

[0075] The working process of the spacing adjustment structure will be described in detail below.

[0076] Reference Figure 3 and Figure 4 , at this time, the spacing between the two adjusting members 21 in the first direction is at its minimum. For ease of description, the end of the worm gear set 411 of the first transmission member 41 meshing with the worm 3 is defined as the first end of the worm 3, and the other end of the worm 3 is defined as the second end. At this time, the extension direction of the second transmission member 42 forms a second predetermined angle with the second direction, and the distance that the limit member 23 extends into the corresponding slide slot 221 is at its maximum. Furthermore, rotation of the first transmission member 41 toward the first end of the worm 3 is defined as clockwise, and rotation toward the second end of the worm 3 is defined as counterclockwise.

[0077] In addition, the two adjusting members 21 are defined as a first adjusting member and a second adjusting member, wherein the first adjusting member is located on the left side of the transmission member 4 in the first direction, and the second adjusting member is located on the right side of the transmission member 4 in the second direction, and in the second direction, the rack 22 connected to the first adjusting member is located above the rack 22 connected to the second adjusting member, and the limit member 23 connected to the first adjusting member is located below the limit member 23 connected to the second adjusting member.

[0078] When the distance between the two adjusting members 21 needs to be increased, the motor 6 drives the worm 3 to rotate forward about its own axis, causing the first transmission member 41 to rotate counterclockwise. The worm gear set 411 on the first transmission member 41 gradually moves toward the second end of the worm 3, while driving the second transmission member 42 to rotate counterclockwise. During the counterclockwise rotation of the second transmission member 42, the transmission gear set 421 of the second transmission member 42 located above in the second direction drives the rack 22 connected to the first adjusting member to move to the left, while the transmission gear set 421 of the second transmission member 42 located below in the second direction drives the rack 22 of the second adjusting member to move to the right. During this process, the length of the limit member 23 extending into the corresponding slide slot 221 gradually decreases.

[0079] When the first transmission member 41 rotates counterclockwise by a preset angle, the worm gear set 411 on the first transmission member 41 moves to the second end of the worm 3. At this time, the distance L between the two adjustment members 21 in the first direction has a maximum value Lmax. Figure 5 and Figure 6 shown.

[0080] Understandably, when the distance between the two adjusting members 21 needs to be reduced, the motor 6 drives the worm 3 to rotate in the opposite direction about its own axis, causing the first transmission member 41 to rotate clockwise. The worm gear set 411 on the first transmission member 41 gradually moves toward the first end of the worm 3, simultaneously driving the second transmission member 42 to rotate clockwise. During the clockwise rotation of the second transmission member 42, the transmission gear set 421 of the second transmission member 42 located above in the second direction drives the rack 22 connected to the first adjusting member to move to the right, while the transmission gear set 421 of the second transmission member 42 located below in the second direction drives the rack 22 of the second adjusting member to move to the left. During this process, the distance that the limit member 23 extends into the corresponding slide slot 221 gradually increases.

[0081] When the first transmission member 41 rotates clockwise by a preset angle, the worm gear set 411 on the first transmission member 41 moves to the first end of the worm 3. At this time, the distance L between the two adjustment members 21 in the first direction has a minimum value Lmin. Figure 3 and Figure 4 shown.

[0082] It should be noted that the above explanation is based on the two limit distances Lmanx and Lmin, but the distance L between the two adjustment members 21 in the first direction can be arbitrarily adjusted within the range of Lmin-Lmax.

[0083] The present disclosure further provides a wearable device including the above-mentioned spacing adjustment structure. The wearable device has the technical effects of the spacing adjustment structure in the above-mentioned embodiment, which will not be described in detail here.

[0084] For example, in one specific implementation, the wearable device can be head-mounted glasses, and the adjustment member 21 is a lens barrel. The distance between the two lens barrels, i.e., the pupil distance, is adjusted by the worm 3, the transmission member 4, and the rack 22. The head-mounted glasses are preferably, but not limited to, VR glasses.

[0085] For example, in a specific implementation, the wearable device may be a VR device.
