[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 11 As shown, an embodiment of this utility model provides a VR glasses, including a housing 1, a lens barrel 7, a lens body 6, a drive component 2, and a transmission mechanism 3. The housing 1 has an installation cavity, the lens barrel 7 is installed in the installation cavity, the lens body 6 passes through the lens barrel 7, and the lens body 6 is anti-rotationally assembled in the installation cavity. The outer peripheral surface of the lens body 6 is provided with an external thread, and the inner wall of the lens barrel 7 is provided with an internal thread. One of the internal thread and the external thread is a threaded protrusion 35, and the other is a threaded groove 34. The threaded protrusion 35 and the threaded groove 34 are threadedly engaged.

[0023] The transmission mechanism 3 is located in the mounting cavity and is connected to the drive member 2 and the lens barrel 7. The housing 1 is provided with a through hole. One end of the drive member 2 extends into the through hole, and the other end of the drive member 2 is exposed outside the housing 1. The drive member 2 can drive the lens barrel 7 to rotate around the first axis through the transmission mechanism 3, so as to drive the lens body 6 to move towards or away from the wearer's eyes.

[0024] In this embodiment, the first axis is the axis of the lens barrel 7, and the extension direction of the axis of the lens barrel 7 is the vertical direction of the VR glasses.

[0025] In this embodiment, the lens body 6 is anti-rotationally mounted in the mounting cavity, meaning that the lens body 6 cannot rotate around the first axis within the mounting cavity.

[0026] In this embodiment, the mounting bracket 11 is installed in the mounting cavity. The mounting bracket 11 is provided with a clearance hole 37 that runs through the mounting bracket 11 in the vertical direction. The upper part of the lens body 6 passes through the lens barrel 7, and the bottom of the lens body 6 passes through the clearance hole 37.

[0027] In this embodiment, a guide block 36 is provided on the outer peripheral surface of the lens body 6. The guide block 36 protrudes from the outer peripheral surface of the lens body 6 and extends in the vertical direction. A guide groove 38 is provided on the inner wall of the clearance hole 37 and extends in the vertical direction. The guide block 36 is slidably assembled in the guide groove 38 in the vertical direction.

[0028] In this embodiment, when the drive member 2 drives the lens barrel 7 to rotate around the first axis through the transmission mechanism 3, the spiral groove will cooperate with the spiral protrusion, causing the lens body 6 to rotate. However, since the mounting bracket 11 is fixed, the guide groove 38 restricts the guide block 36, thereby restricting the rotation of the lens body 6. Therefore, when the lens barrel 7 rotates, the spiral groove will force the spiral protrusion to drive the lens body 6 to rise and fall, thereby causing the lens body 6 to move closer to or further away from the wearer's eyes, thereby adjusting the distance between the lens body 6 and the human eye, and thus adjusting the diopter of the VR glasses.

[0029] In this embodiment, the drive component 2 is exposed outside the housing 1. The user can drive the lens barrel 7 to rotate through the drive component 2 and the transmission mechanism 3 without having to put their hand into the gap between their head and the VR glasses to manually rotate the lens barrel 7, so that the lens body 6 can move closer to or further away from the wearer's eyes to adjust the distance between the lens body 6 of the VR glasses and the user's eyes, which is convenient for operation. In addition, the cooperation between the spiral protrusion and the spiral groove also makes the transmission between the lens body 6 and the lens barrel 7 more stable.

[0030] In one embodiment, a driven rack 33 is provided on the outer peripheral surface of the lens barrel 7, and the driven rack 33 is arranged around the lens body 6.

[0031] The transmission mechanism 3 includes a transmission component 4 and a transmission gear component 5. The transmission gear component 5 meshes with the driven rack 33.

[0032] The second axis is perpendicular to the first axis.

[0033] In this embodiment, the first direction is the left-right direction of the VR glasses, and the second axis extends along the left-right direction of the VR glasses.

[0034] In this embodiment, the driven rack 33 is arranged around the lens body 6.

[0035] In this embodiment, the transmission component 4 is connected between the driving component 2 and the transmission gear component 5.

[0037] One end of the transmission component 4 is connected to the driving component 2. The end of the transmission component 4 near the mirror barrel 7 is provided with a drive gear 25. The drive gear 25 meshes with the second gear part 30. The driving component 2 can drive the transmission component 4 to rotate around the second axis.

[0038] In this embodiment, the drive gear 25 is disposed at the end of the transmission component 4 and is integrally formed with the transmission component 4.

[0039] In this embodiment, the end of the transmission member 4 away from the drive gear 25 is connected to the drive member 2, and the drive member 2 drives the transmission member 4 and the drive gear 25 to rotate.

[0040] In this embodiment, the first gear section 28 and the second gear section 30 are designed as a single unit.

[0041] In this embodiment, the driving gear 25 meshes with the second gear section 30. When the driving gear 25 rotates, it drives the second gear section 30 to drive the first gear section 28 to rotate, thereby causing the driven rack 33 meshing with the first gear section 28 to drive the mirror barrel 7 to rotate.

[0042] In this embodiment, the transmission gear 5 is driven to rotate by the drive gear 25, which has a simple structure, is easy to design and install, and can save production costs.

[0043] In one embodiment, the diameter of the first gear portion 28 is larger than the diameter of the second gear portion 30.

[0044] In this embodiment, the diameter of the first gear portion 28 is larger than the diameter of the second gear portion 30, so that a first stop surface is formed between the first gear portion 28 and the second gear portion 30. The first stop surface can stop the drive gear 25 and prevent the drive gear 25 from meshing with the first gear portion 28.

[0045] In one embodiment, the drive member 2 includes a knob part 12 and a drive part 13. The knob part 12 is exposed outside the housing 1, and the drive part 13 is disposed through the perforation.

The mounting plate 16 has a mounting hole 18 inside, which extends in the left and right direction. The mounting plate 16 has a first mounting ear 43 on its outer peripheral surface, which is screwed to the housing 1 in the mounting cavity.

[0047] In this embodiment, the drive unit 13 includes a first segment 14 and a second segment 15. The first segment 14 is provided with a first connecting hole 22 on one end face away from the second segment 15. The knob part 12 is provided with a knob hole 20 extending in the left and right direction. The bottom wall of the knob hole 20 is provided with a second connecting hole 21. The first connecting hole 22 and the second connecting hole 21 are connected by screws.

[0048] A baffle 19 for blocking the knob hole 20 is provided on the end face of the knob part 12 away from the drive part 13.

[0049] The diameter of the second segment 15 is larger than the diameter of the first segment 14. The diameter of the second segment 15 is larger than the diameter of the mounting hole 18. The first segment 14 passes through the mounting hole 18. The side of the second segment 15 facing away from the lens barrel 7 is engaged with the side of the mounting plate 16 facing the lens barrel 7 to prevent the drive component 2 from detaching from the housing 1.

[0050] The drive unit 13 has a drive hole 23 at the end away from the knob 12. A retaining plate 24 is provided on the inner wall of the drive hole 23. A slot 27 is provided on the outer peripheral surface of the transmission component 4. The end of the transmission component 4 away from the lens barrel 7 is inserted into the drive hole 23, and the retaining plate 24 is inserted into the slot 27, so as to realize the anti-rotation connection between the drive unit 13 and the transmission component 4, so as to drive the transmission component 4 and the drive gear 25 to rotate when the drive unit 13 rotates.

[0051] In this embodiment, the mounting plate 16 is provided with a limiting cylinder 17 extending in the left-right direction of the eye on one side facing the lens barrel 7. The limiting cylinder 17 is sleeved on the second section 15. The setting of the limiting cylinder 17 can ensure the coaxiality of the drive part 13 and the drive gear 25, avoid the shaking when the drive part 2 and the transmission part 4 rotate, and make the drive gear 25 more stable when rotating.

[0052] In one embodiment, the second axis extends along the first direction.

[0053] The lens barrel 7 is rotatably assembled with the mounting bracket 11 around the first axis. The mounting bracket 11 has a first rotating shaft 40 on the side facing the drive member 2. The first rotating shaft 40 extends along the first direction. The transmission gear member 5 is rotatably assembled with the first rotating shaft 40 around the second axis.

[0054] In this embodiment, the lens barrel 7 is rotatably mounted on the mounting bracket 11.

[0055] In this embodiment, the first rotating shaft 40 has a columnar structure and is located on one side of the mounting bracket 11 facing the drive member 2. The first rotating shaft 40 extends in the left-right direction.

[0056] In this embodiment, the transmission gear 5 is mounted on the first rotating shaft 40.

[0057] In this embodiment, the first rotating shaft 40 and the mounting bracket 11 are designed as a single unit.

[0058] In one embodiment, a first stop plate is provided at the end of the first rotating shaft 40 away from the lens barrel 7, and the side of the second gear part 30 facing away from the first gear part 28 abuts against the side of the first stop plate facing the lens barrel 7.

[0059] In this embodiment, the first stop plate is circular and its diameter is larger than that of the second gear hole 31. The first stop plate can stop the transmission gear 5 in the left and right directions to prevent the transmission gear 5 from disengaging from the first rotating shaft 40.

[0060] In this embodiment, a screw hole is provided on the end face of the small diameter section 42 away from the large diameter section 41, and the first stop plate is connected to the small diameter section 42 by screws, which makes disassembly and assembly convenient.

[0061] In one embodiment, the first rotating shaft 40 includes a large diameter section 41 and a small diameter section 42. The first gear section 28 is provided with a first gear hole 29, through which the large diameter section 41 passes. The second gear section 30 is provided with a second gear hole 31, through which the small diameter section 42 passes.

[0062] The diameter of the first gear hole 29 is larger than the diameter of the second gear hole 31. A first stop step 44 is formed between the major diameter section 41 and the minor diameter. A second stop step 32 is formed between the first gear hole 29 and the second gear hole 31. The first stop step 44 and the second stop step 32 are in a stop-fitting relationship.

[0063] In this embodiment, the first stop step 44 and the second stop step 32 engage to limit the transmission gear 5 in the direction closer to the mirror barrel 7. Under the synergistic effect of the first stop plate, the displacement of the transmission gear 5 in the action direction is restricted, so that the transmission gear 5 can only rotate around the first rotating shaft 40, thus preventing the transmission gear 5 from disengaging from the driven rack 33 or the driving gear 25.

[0064] In one embodiment, a straight tube is provided around the clearance hole 37 on the mounting bracket 11, and the lens tube 7 is sleeved on the straight tube.

[0065] In this embodiment, the mounting bracket 11 is fitted onto the straight cylinder. When the driving member 2 drives the driven rack 33 to rotate around the lens body 6, the lens barrel 7 rotates around the straight cylinder, providing a mounting position for the lens barrel 7.

[0066] In this embodiment, the mounting bracket 11 is provided with two limiting blocks 39, and the driven rack 33 is located between the two limiting blocks 39. The area between the two limiting blocks 39 is the maximum range in which the lens barrel 7 can rotate.

[0067] In this embodiment, a second rotating shaft 45 is provided on the mounting bracket 11 above the first rotating shaft 40, and the driving gear 25 is provided with a driving hole 26. The second rotating shaft 45 is inserted into the driving hole 26, so that the driving gear 25 can rotate around the second rotating shaft 45.

[0068] In this embodiment, a second stop plate 46 is provided at the end of the second rotating shaft 45 away from the lens barrel 7. The connection method between the second stop plate 46 and the second rotating shaft 45 is the same as the connection method between the first stop plate and the first rotating shaft 40.

[0069] In this embodiment, the second stop plate 46 is circular and its diameter is larger than that of the active hole 26. The screw that connects the second stop plate 46 to the second rotating shaft 45 passes through the active hole 26 and is threaded onto the second rotating shaft 45, so that the active gear 25 is clamped between the second stop plate 46 and the mounting bracket 11, thereby limiting the active gear 25 in the left and right directions.

[0070] In one embodiment, a guide rod 10 and a translation mechanism are further provided inside the mounting cavity. The guide rod 10 is horizontally mounted inside the mounting cavity in a left-right direction, and the mounting frame 11 is slidably mounted on the guide rod 10. The translation mechanism can drive the mounting frame 11 to slide in a left-right direction. In this embodiment, the translation mechanism driving the mounting frame 11 to slide left and right is prior art and will not be described in detail here.

[0071] In one embodiment, the VR glasses also include a sleeve 8, with a second mounting ear 9 provided on the outer peripheral surface of the sleeve 8. The second mounting ear 9 is screwed to the mounting bracket 11. The sleeve 8 is fitted onto the lens barrel 7. The bottom surface of the second mounting ear 9 contacts the upper surface of the driven rack 33, thereby clamping the driven rack 33 between the second mounting ear 9 and the upper surface of the mounting bracket 11, thereby limiting the lens barrel 7 in the vertical direction.

[0072] In this embodiment, it should be noted that, relying on the friction between the lens body 6 and the lens barrel 7, the friction between the second gear part 30 and the driving gear 25, the friction between the first gear part 28 and the driven rack 33, and the friction between the driving part 13 and the mounting hole 18, the distance between the lens body 6 and the wearer's eyes can be stably maintained without the action of external force.

[0073] 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.

[0074] According to the VR glasses provided in this embodiment of the present invention, the driving component 2 is exposed outside the housing 1. The user can drive the lens barrel 7 to rotate through the driving component 2 and the transmission mechanism 3 without having to put their hand into the gap between their head and the VR glasses to manually rotate the lens barrel 7, so that the lens body 6 moves closer to or further away from the wearer's eyes, thereby adjusting the distance between the lens body 6 of the VR glasses and the user's eyes, which is convenient for operation. In addition, the cooperation between the spiral protrusion and the spiral groove also makes the transmission between the lens body 6 and the lens barrel 7 more stable.

[0075] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
