[0020] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 8 As shown, this utility model embodiment provides a VR glasses, including a housing 1, a first lens 3, a second lens 4 and a driving assembly. The housing 1 is provided with a mounting cavity 2. The first lens 3 is slidably assembled in the mounting cavity 2 along a first direction, and the second lens 4 is slidably assembled in the mounting cavity 2 along the first direction. The first lens 3 and the second lens 4 are spaced apart along the first direction.

[0023] The driving component can drive the first lens 3 and the second lens 4 to move towards each other or away from each other along a first direction.

[0024] In this embodiment, the first lens 3 is slidably mounted in the mounting cavity 2 along the first direction, and the second lens 4 is slidably mounted in the mounting cavity 2 along the first direction. When the user uses the VR glasses, the first lens 3 and the second lens 4 can be driven to move closer or further apart by the driving component, without having to put their hand into the gap between the VR glasses and the user's eyes, making the operation simple.

[0025] In this embodiment, a mounting bracket 17 is provided in the mounting cavity 2. The mounting bracket 17 is connected to the housing 1. The first lens 3 is slidably mounted on the mounting bracket 17 along the first direction, and the second lens 4 is slidably mounted on the mounting bracket 17 along the first direction.

[0026] In one embodiment, the drive assembly includes a drive mechanism 6 and a transmission mechanism 5. The transmission mechanism 5 includes a first gear 11, a first rack 9 and a second rack 10. The first rack 9 and the second rack 10 extend along a first direction. The first rack 9 is connected to the first lens 3 and the second rack 10 is connected to the second lens 4.

[0027] The first gear 11 is rotatably assembled with the housing 1 around the first axis. The first rack 9 and the second rack 10 mesh on opposite sides of the first gear 11 along the second direction. The drive mechanism 6 can drive the first gear 11 to rotate around the first axis, so as to drive the first rack 9 and the second rack 10 to move in opposite directions. The second direction is perpendicular to the first direction.

[0028] In this embodiment, since the first rack 9 and the second rack 10 mesh on opposite sides of the first gear 11, when the drive mechanism 6 drives the first gear 11 to rotate, the first rack 9 and the second rack 10 will move synchronously towards or away from each other, so that the first lens 3 and the second lens 4 move closer or further apart, thereby adjusting the distance between the first lens 3 and the second lens 4 to adjust the IPD (interpupillary distance) of the VR glasses. Using a rack and pinion structure to drive the first lens 3 and the second lens 4 to move synchronously facilitates design.

[0029] In this embodiment, the first direction is the left-right direction of the VR glasses (i.e., the left-right direction of the VR glasses when the user wears the glasses), the second direction is the up-down direction (i.e., the up-down direction of the VR glasses when the user wears the VR glasses), and the extension direction of the first axis is the front-back direction (i.e., the front-back direction of the VR glasses when the user wears the VR glasses).

[0030] In one embodiment, the transmission mechanism 5 further includes a second gear 12 coaxially connected to the first gear 11, the diameter of the second gear 12 being larger than the diameter of the first gear 11.

[0031] The drive mechanism 6 can drive the second gear 12 to rotate around the first axis.

[0032] In this embodiment, the second gear 12 is coaxially arranged with the first gear 11. The diameter of the second gear 12 is larger than the diameter of the first gear 11. The drive mechanism 6 drives the first gear 11 to rotate by driving the second gear 12 to rotate. The arrangement of the second gear 12 allows the drive mechanism 6 to be arranged in layers with the first gear 11, which facilitates the rational use of the internal space of the VR glasses and helps to lock the overall size of the VR glasses.

[0033] In this embodiment, the second gear 12 is located below the first gear 11 (i.e., close to the user's eyes when the user wears VR glasses).

[0034] In this embodiment, the side of the first gear 11 facing the second gear 12 is connected to the side of the second gear 12 facing the first gear 11, so that the first gear 11 and the second gear 12 form a stepped structure, and the first gear 11 and the second gear 12 rotate synchronously around the first axis.

[0035] In this embodiment, the mounting bracket 17 is provided with a receiving hole 25, and a support plate 27 is provided at the bottom of the receiving hole 25. The support plate 27 is horizontally arranged across the bottom of the receiving hole 25, and one end of the rotating shaft 28 is connected to the side of the support plate 27 facing the first gear 11.

[0036] In this embodiment, the rotating shaft 28 includes a large diameter section 29 and a small diameter section 30. The second gear 12 is sleeved on the large diameter section 29 and is located in the receiving hole 25. The receiving hole 25 of the mounting bracket 17 is provided with a notch 26. The notch 26 is opposite to the rack guide groove 34, so that the third rack 13 meshes with the second gear 12 through the notch 26.

[0037] In this embodiment, the first gear 11 is fitted onto the small diameter section 30.

[0038] In this embodiment, a limiting ring groove 31 is also provided at the top of the small diameter section 30, and the transmission mechanism 5 also includes a limiting clamp 32. The limiting clamp 32 is clamped in the limiting ring groove 31 to limit the first gear 11 and the second gear 12 in the axial direction of the rotating shaft 28, so as to prevent the first gear 11 and the second gear 12 from falling off the rotating shaft 28.

[0039] In this embodiment, the large-diameter section 29 is located on the mounting bracket 17, and the small-diameter section 30 can be detachably connected to the large-diameter section 29, which facilitates manufacturing.

[0040] In one embodiment, the drive mechanism 6 includes a drive member 14 and a third rack 13, the third rack 13 extending along a first direction and meshing with a second gear 12.

[0041] The third rack 13 is slidably assembled in the mounting cavity 2 along the first direction.

[0042] The drive unit 14 can drive the third rack 13 to move in the first direction, so as to drive the second gear 12 to rotate.

[0043] In this embodiment, the driving member 14 drives the third rack 13 to slide in the first direction, so that the third rack 13 drives the second gear 12 to rotate. The structure is simple and easy to design because the third rack 13 drives the second gear 12 to rotate.

[0044] In this embodiment, the mounting bracket 17 is provided with a bracket 22, and the bracket 22 is provided with a rack mounting groove 23 on one side facing the second gear 12. The rack mounting groove 23 extends along the first direction, and the third rack 13 is slidably assembled in the rack mounting groove 23. The driving member 14 drives the third rack 13 to slide in the rack mounting groove 23 along the first direction.

[0045] In one embodiment, the driving member 14 includes a driving rod 15. A driving elongated hole 33 is provided on the groove wall of the housing 1 facing the second gear 12. The driving rod 15 passes through the driving elongated hole 33. One end of the driving rod 15 is connected to the side of the third rack 13 facing away from the second gear 12. The other end of the driving rod 15 extends out of the housing 1 through the driving elongated hole 33.

[0046] In this embodiment, the third rack 13 is driven by the drive rod 15, which is simple in structure and easy to design.

[0047] In this embodiment, the drive elongated hole 33 extends along the first direction, and the bottom wall of the rack mounting groove 23 is provided with a transition elongated hole 24. The transition elongated hole 24 extends along the first direction and is positioned opposite to the drive elongated hole 33.

[0048] In this embodiment, the drive rod 15 passes through the transition elongated hole 24 and the drive elongated hole 33. One end of the drive rod 15 extends into the mounting cavity 2 and is connected to the side of the third rack 13 facing away from the second gear 12. The other end of the drive rod 15 is exposed outside the housing 1, so that the user can push the drive rod 15 in the first direction, causing the drive rod 15 to drive the third rack 13 to move in the first direction.

[0049] In one embodiment, the drive member 14 further includes a drive button 16. One end of the drive rod 15 extending out of the housing 1 is connected to the drive button 16. By pushing the drive button 16 to move in the first direction, the third rack 13 is driven to move in the first direction.

[0050] In this embodiment, the diameter of the drive button 16 is larger than the diameter of the drive rod 15. The drive button 16 is connected to the end of the drive rod 15 that is exposed in the housing 1. By pushing the drive button 16, the drive rod 15 is driven to move, which is convenient for operation.

[0051] In one embodiment, a guide groove 34 is provided on the outer wall surface of the housing 1. The guide groove 34 communicates with the drive elongated hole 33. The end of the drive button 16 near the drive rod 15 is slidably assembled in the guide groove 34 along the first direction.

[0052] In this embodiment, a guide groove 34 is provided on the outer wall surface of the housing 1. The guide groove 34 extends along the first direction. One end of the drive button 16 near the drive rod 15 is slidably mounted in the guide groove 34 along the first direction. The other end of the drive button 16 extends out of the guide groove 34 for the user to push.

[0053] In this embodiment, the guide groove 34 serves as a limit for the drive button 16, preventing the drive button 16 from shaking.

[0054] In one embodiment, the VR glasses also include a first base 7, a first lens 3 mounted on the first base 7, and a first rack 9 connected to the first base 7.

[0055] The first base 7 has a first protrusion 35 on the side facing away from the first lens 3, and the first protrusion 35 has a first through hole 36.

[0056] The housing 1 is provided with a first guide rod 19 extending in a first direction. The first guide rod 19 passes through the first through hole 36 and is slidably assembled with the first through hole 36 in the first direction.

[0057] In this embodiment, the first guide rod 19 extends along a first direction.

[0058] In this embodiment, the mounting bracket 17 has two first fixing plates 18 on the side facing the first lens 3, and the two ends of the first guide rod 19 are respectively connected to the two first fixing plates 18, so that there is a gap between the first guide rod 19 and the mounting bracket 17.

[0059] In this embodiment, the first guide rod 19 passes through the first through hole 36 of the first protrusion 35, so that the first protrusion 35 can slide between the two first fixing plates 18, thereby driving the first lens 3 to slide between the two first fixing plates 18. The first lens 3 is mounted on the first base 7, thereby realizing the sliding assembly between the first lens 3 and the housing 1.

[0060] In this embodiment, the first lens 3 is mounted in the direction of the guide rod, which is simple in structure and easy to design.

[0061] In one embodiment, the VR glasses further include a second base 8, a second lens 4 mounted on the second base 8, and a second rack 10 connected to the second base 8; The second base 8 has a second protrusion 37 on the side facing away from the second lens 4, and the second protrusion 37 has a second through hole 38; The housing 1 is provided with a second guide rod 21 extending in a first direction. The second guide rod 21 passes through the second through hole 38 and is slidably assembled with the second through hole 38 in the first direction.

[0062] In this embodiment, the second guide rod 21 extends along the second direction.

[0063] In this embodiment, the mounting bracket 17 has two second fixing plates 20 on the side facing the second lens 4, and the two ends of the second guide rod 21 are respectively connected to the two second fixing plates 20, so that there is a gap between the second guide rod 21 and the mounting bracket 17.

[0064] In this embodiment, the second guide rod 21 passes through the second through hole 38 of the second protrusion 37, so that the second protrusion 37 can slide between the two second fixing plates 20, thereby driving the second lens 4 to slide between the two second fixing plates 20. The second lens 4 is mounted on the second base 8, thereby realizing the sliding assembly between the second lens 4 and the housing 1.

[0065] In this embodiment, the second lens 4 is installed using a guide rod, which is simple in structure and easy to design.

[0066] In one embodiment of the present invention, the VR glasses provided allow the user to first wear the VR glasses on their head. If the distance between the first lens 3 and the second lens 4 does not match the interpupillary distance between the user's eyes, the user can manually push the drive button 16. The drive button 16 drives the third rack 13 to move via the drive rod 15. When the third rack 13 moves, it drives the second gear 12 to rotate. The second gear 12 drives the first gear 11 to rotate. When the first gear 11 rotates, it causes the first rack 9 and the second rack 10 to move closer or further apart, thereby causing the first lens 3 and the second lens 4 to move closer or further apart, thus adjusting the distance between the first lens 3 and the second lens 4.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
