[0030] 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.

[0031] 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.

[0032] like Figures 1 to 10 As shown, an embodiment of this utility model provides VR glasses, including a housing 1, a lens barrel 4, a lens body 3, a driving component 9, a transmission mechanism, and a second transmission mechanism. The housing 1 has a mounting cavity 2, the lens barrel 4 is installed in the mounting cavity 2, the lens body 3 passes through the lens barrel 4, the lens body 3 is rotatably assembled with the lens barrel 4 around the axis of the lens barrel 4, and the lens barrel 4 is rotatably assembled with the housing 1 around the axis of the lens barrel 4. The transmission mechanism is installed in the mounting cavity 2 and is tractively connected between the driving component 9 and the lens barrel 4. The housing 1 has a through hole 10, the driving component 9 passes through the through hole 10, and the driving component 9 is exposed outside the housing 1. The driving component 9 can drive the lens barrel 4 to rotate around the first axis through the transmission mechanism, so as to drive the lens body 3 to extend or retract the lens barrel 4.

[0033] In this embodiment, the drive unit 9 is exposed outside the housing 1. The user can drive the lens barrel 4 to rotate through the drive unit 9 and the transmission mechanism without having to put their hand into the gap between their head and the VR glasses to manually rotate the lens barrel 4 so that the lens body 3 can extend or retract into the lens barrel 4, thereby adjusting the distance between the lens body 3 of the VR glasses and the user's eyes, which is convenient for operation.

[0034] In this embodiment, the first axis is the axis of the lens barrel 4.

[0035] In this embodiment, the VR glasses also include a limiting sleeve 6, which is sleeved on the lens body 3, and the lens barrel 4 is sleeved on the limiting sleeve 6. The bottom end of the limiting sleeve 6 is connected to the housing 1.

[0036] The limiting cylinder 6 is provided with a limiting hole 15 extending in the vertical direction. The inner wall surface of the lens barrel 4 is provided with a guide groove 13, which is spiral in shape. The outer peripheral surface of the lens body 3 is provided with a guide post 16. The guide post 16 extends into the guide groove 13 through the limiting hole 15. When the lens barrel 4 rotates, due to the limiting of the limiting cylinder 6, the guide groove 13 forces the guide post 16 to rise and fall, thereby driving the lens body 3 to rise and fall.

[0037] In this embodiment, a limiting ring platform 14 is provided on the outer peripheral surface of the limiting cylinder 6, and the bottom end of the mirror cylinder 4 sits on the upper step surface of the limiting ring platform 14.

[0038] In one embodiment, the transmission mechanism includes a transmission member 11 and a transmission gear. A driven gear 5 is provided on the outer peripheral surface of the lens barrel 4. The transmission member 11 is connected to the driving member 9 and the transmission gear. The transmission gear meshes with the driven gear 5. The driving member 9 drives the transmission gear to rotate around the second axis through the transmission member 11.

[0039] In this embodiment, the driven gear 5 is specifically an annular rack 22, which is arranged around the axis of the lens barrel 4. The inner side of the annular rack 22 is connected to the outer peripheral surface of the lens barrel 4, and the outer side of the annular rack 22 meshes with the transmission gear.

[0040] In this embodiment, the transmission gear is rotatably mounted inside the housing 1, and the driving component 9 can drive the transmission gear to rotate, thereby causing the transmission gear to drive the driven gear 5 to rotate. The gear transmission structure is simple and easy to design.

[0041] In one embodiment, the transmission gear and the driven gear 5 are bevel gears, and the second axis is perpendicular to the first axis.

[0042] In this embodiment, the transmission gear is a bevel gear, the second axis is the axis of the transmission gear, the axis of the transmission gear is perpendicular to the axis of the mirror barrel 4, and the transmission gear is connected to the driving component 9.

[0043] In this embodiment, the outer side of the annular rack 22 has tapered teeth, and the axis of the driven gear 5 is perpendicular to the axis of the transmission gear. This reduces the internal space of the housing 1 occupied by the transmission gear, thereby reducing the overall size of the VR glasses.

[0044] In one embodiment, the transmission member 11 includes a first connecting portion 36 and a second connecting portion 39. The first connecting portion 36 is connected to the driving member 9, and the end of the second connecting portion 39 away from the first connecting portion 36 is connected to the transmission gear to prevent rotation. The driving member 9 can drive the transmission member 11 to rotate around the second axis, so that the transmission member 11 drives the transmission gear to rotate around the second axis.

[0045] In this embodiment, the first connecting part 36 is connected to the driving member 9, and the second connecting part 39 is connected to the transmission gear to prevent rotation, so that the driving member 9 drives the transmission gear to rotate through the transmission member 11.

[0046] In one embodiment, a rectangular insertion block 24 is provided on the side of the transmission gear facing the drive member 9, and a rectangular first insertion hole 23 is provided on the side of the second connecting part 39 facing the lens barrel 4. The insertion block 24 is inserted into the first insertion hole 23.

[0047] In this embodiment, the rectangular plug-in block 24 is plugged into the rectangular first plug-in hole 23 to achieve an anti-rotation connection between the second connecting part 39 and the transmission gear, which is convenient for design and manufacturing.

[0048] In other embodiments, the plug block 24 can be circular, the first plug hole 23 can be circular, and the plug block 24 and the first plug hole 23 are interference-fitted together.

[0049] In one embodiment, the VR glasses also include a locking mechanism 31, which can lock the transmission member 11.

[0050] In this embodiment, the locking mechanism 31 can lock the transmission member 11 at the required angle to prevent the lens barrel 4 from resetting on its own.

[0051] In one embodiment, the locking mechanism 31 includes an elastic member 34 and a locking member 35. An annular locking block 37 is provided on the outer peripheral surface of the first connecting portion 36, and a plurality of lock grooves 38 are provided on the annular locking block 37.

[0052] The housing 1 is provided with a mounting bracket 25. One end of the elastic member 34 is connected to the side of the mounting bracket 25 facing the first connecting part 36. The locking member 35 is connected to the other end of the elastic member 34. The locking member 35 can be inserted into the locking groove 38. By driving the first connecting part 36 to rotate, the locking member 35 can be driven to disengage from the current locking groove 38 and slide into another adjacent locking groove 38.

[0053] In this embodiment, the mounting bracket 25 includes two connecting arms 26 and a mounting cylinder 27. The two connecting arms 26 are arranged symmetrically about the axis of the transmission gear, and the mounting cylinder 27 is located between the two connecting arms 26.

[0054] Two connecting ears 28 are provided on the outer circumferential surface of the mounting cylinder 27, which are symmetrically arranged about the axis of the transmission gear. One connecting arm 26 is connected to the housing 1 at one end away from the transmission gear, and the other end is detachably connected to one of the connecting ears 28. The other connecting arm 26 is connected to the housing 1 at one end away from the transmission gear, and the other end is detachably connected to the other connecting ear 28, so as to support the lens barrel 4.

[0055] A protrusion 32 is provided on the outer peripheral surface of the mounting cylinder 27. The side of the protrusion 32 facing the first connecting part 36 is provided with a mounting groove 33 that communicates with the cylinder cavity of the mounting cylinder 27. One end of the elastic member 34 is connected to the bottom wall of the mounting groove 33, and the locking member 35 is connected to the other end of the elastic member 34.

[0056] In this embodiment, the elastic element 34 is a spring.

[0057] In this embodiment, the locking element 35 is a locking ball, and the locking groove 38 is an arc-shaped groove.

[0058] In this embodiment, the spring-driven locking ball engages in the locking groove 38 of the first connecting part 36. When the transmission member 11 is rotated, the first connecting part 36 rotates relative to the mounting cylinder 27, and the mounting cylinder 27 is fixed, causing the locking ball to disengage from one of the locking grooves 38 into which it is engaged and slide into another locking groove 38 adjacent to that groove. The cooperation between the elastic member 34 and the locking member 35 is relatively simple.

[0059] In one embodiment, the driving member 9 includes a knob portion 40 and a driving portion 41. The knob portion 40 is exposed outside the housing 1, and the driving portion 41 passes through the through hole 10 and is connected to the first connecting portion 36.

[0060] In this embodiment, the driving component 9 is circular.

[0061] In this embodiment, the knob part 40 is exposed outside the housing 1, and the drive part 41 is inserted through the through hole 10.

[0062] In this embodiment, the first connecting portion 36 and the second connecting portion 39 are circular, the diameter of the first connecting portion 36 is smaller than the diameter of the second connecting portion 39, and the diameter of the first connecting portion 36 is the same as the diameter of the drive.

[0063] In this embodiment, the mounting cylinder 27 includes a large-diameter section 29 and a small-diameter section 30. The large-diameter section 29 is fitted onto the annular locking block 37 and abuts against the side of the first connecting part 36 facing away from the transmission gear. The small-diameter section 30 is fitted onto the driving part 41 and the first connecting part 36. The space enclosed by the first connecting part 36 and the large-diameter section 29 is for the annular locking block 37 to be installed.

[0064] In one embodiment, the driving part 41 has a second insertion hole 43 on the side facing the first connecting part 36, and the first connecting part 36 has a plurality of insertion posts 42 on the side facing the driving part 41, and the plurality of insertion posts 42 are inserted into the plurality of second insertion holes 43 in a one-to-one correspondence.

[0065] In this embodiment, the second insertion hole 43 is interference-fitted with the insertion post 42.

[0066] In one embodiment, the second axis extends along the first direction, and the VR glasses also include a barrel frame 8. The barrel frame 8 is slidably assembled with the housing 1 along the first direction. The lens barrel 4 is rotatably sleeved on the barrel frame 8. The barrel frame 8 is provided with a mounting plate 19. The mounting plate 19 is provided with a rotating shaft 20 on the side facing the transmission gear. The transmission gear is provided with a rotating hole on the side facing the mounting plate 19. The side of the mounting plate 19 facing the transmission gear abuts against the side of the transmission gear facing away from the drive member 9. The rotating shaft 20 is inserted into the rotating hole.

[0067] In this embodiment, the first direction is perpendicular to the axial direction of the lens barrel 4 and is the left-right direction of the housing 1.

[0068] In this embodiment, the VR glasses also include a drive mechanism and a ring-shaped first connecting plate 21.

[0069] In this embodiment, the barrel frame 8 is fitted onto the upper half of the lens body 3. The inner circumferential surface of the barrel frame 8 slides in contact with the outer circumferential surface of the lens body 3. The lens body 3 moves up and down relative to the barrel frame 8. An annular second connecting plate 17 is provided on the outer circumferential surface of the barrel frame 8. The second connecting plate 17 is fitted onto the lens barrel 4. A connecting post 18 is provided on the second connecting plate 17. The connecting post 18 abuts against the first connecting plate 21. The connecting post 18 is bolted to the first connecting plate 21.

[0070] In this embodiment, the length of the first insertion hole 23 is slightly greater than the length of the insertion block 24, so that the insertion block 24 can move relative to the transmission member 11 in the first direction.

[0071] In this embodiment, a rack 22 extending in a first direction is provided on the outer peripheral surface of the first connecting plate 21, and the driving mechanism can be a gear mechanism that cooperates with the rack 22 to make the first connecting plate 21 move in the first direction.

[0072] In this embodiment, the rotating shaft 20 is screwed to the second connecting part 39. The screw fixes the rotating shaft 20 and the second connecting part 39 relative to each other in the first direction, but does not limit the relative rotation between the rotating shaft 20 and the second connecting part 39.

[0073] In this embodiment, the first connecting plate 21 drives the barrel frame 8, lens body 3, limiting cylinder 6 and lens barrel 4 to translate. When the barrel frame 8 moves, the mounting plate 19 forces the drive gear 12 to move along the first direction. At the same time, the driven gear 5 on the lens barrel 4 also moves with the lens barrel 4 to prevent the driven gear 5 from disengaging from the drive gear 12.

[0074] In one embodiment, a sliding plate 7 is further provided in the mounting cavity 2. The sliding plate 7 is slidably assembled with the housing 1, and the limiting cylinder 6 is connected to the sliding plate 7. Specifically, the bottom end of the limiting cylinder 6 is connected to the upper side of the sliding plate 7, the lower side of the sliding plate 7 is provided with a slide rail extending in a first direction, and the housing 1 is provided with a slide groove extending in the first direction. The slide rail is slidably assembled in the slide groove.

[0075] The VR glasses provided in this embodiment of the utility model allow the user to rotate the knob 40, causing the transmission component 11 to drive the active gear 12 to rotate. The active gear 12 drives the driven gear 5 to rotate, thereby causing the lens barrel 4 to rotate. When the lens barrel 4 rotates, the guide groove 13 of the lens barrel 4 cooperates with the guide post 16 of the lens body 3, causing the lens body 3 to rise and fall relative to the lens barrel 4.

[0076] 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.

[0077] According to the VR glasses provided in this embodiment of the present invention, the driving component 9 is exposed outside the housing 1. The user can drive the lens barrel 4 to rotate through the driving component 9 and the transmission mechanism. There is no need to put your hand into the gap between your head and the VR glasses to manually rotate the lens barrel 4 so that the lens body 3 can extend or retract into the lens barrel 4, thereby adjusting the distance between the lens body 3 of the VR glasses and the user's eyes, which is convenient for operation.

[0078] 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.
