Description

VR glasses Technical Field

[0001] This invention relates to the field of virtual reality, and more particularly to a VR headset. Background Technology

[0002] Virtual Reality (VR) headsets are products that combine simulation technology with computer graphics, human-computer interface technology, multimedia technology, sensor technology, and network technology. They represent a novel means of human-computer interaction created using computers and the latest sensor technologies. VR glasses not only bring surprise and joy to every enthusiast, but also deeply fascinate them because of the unknown surrounding their origins and future prospects. Technical issues

[0003] The VR glasses based on this technology include a frame body, a left lens module and a right lens module mounted on the frame body, an adjustment mechanism for adjusting the interpupillary distance of the left and right lens modules, and a head-mounted structure fixed to the frame body. The adjustment mechanism includes a gear transmission component and two racks connected to the gear transmission component. The two racks are respectively connected to the left and right lens modules. When the head-mounted structure is placed on the user's head, the left and right eyes correspond to the left and right lens modules respectively. By driving the adjustment mechanism, the two racks are moved, thereby adjusting the interpupillary distance between the left and right lens modules and improving the VR experience.

[0004] However, related VR glasses use motors to drive an adjustment mechanism that moves the left and right lens modules to adjust interpupillary distance. These glasses also employ a method where two racks have their teeth aligned in the same direction, meshing with two output gears to achieve transmission. This means one output rack meshes with the other output gear, causing the two racks to mesh together.

Embodiments of the present invention

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please refer to Figures 1-8. The present invention provides a VR glasses 100, which includes a frame body 1, a first mounting hole 2 and a second mounting hole 3 that pass through the frame body 1 and are spaced apart from each other, and a first lens module 4 and a second lens module 5 respectively installed in the first mounting hole 2 and the second mounting hole 3. The lateral diameter of the first mounting hole 2 and the lateral diameter of the second mounting hole 3 are respectively larger than the diameter of the first lens module 4 and the diameter of the second lens module 5. The VR glasses 100 also includes a drive module 6 fixed to the frame body 1 and located between the first lens module 4 and the second lens module 5. The drive module 6 is used to drive the first lens module 4 and the second lens module 5 to move synchronously towards each other or synchronously in opposite directions to achieve interpupillary distance adjustment.

[0033] The VR glasses also include an eye mask 105 fixed to the main body 1 of the frame, fixing posts 101 fixed to both sides of the main body 1 of the frame, a baffle 104 sleeved on the fixing posts 101, a headband 102 sleeved on the side of the fixing posts 101 away from the baffle 104, and a locking member 103 that fixes the headband 102 to the fixing posts 101. The headband 102 is placed on the user's head, with the left and right eyes corresponding to the first lens module 4 and the second lens module 5 respectively, and is fixed by the locking member 103.

[0034] The drive module 6 includes a frame 61 fixed to the main body 1 of the eyeglass frame, a drive unit 62 fixed to one side of the frame 61, a gear component 63 rotatably disposed within the frame 61 and transmitted through the drive unit 62, and a first rack 64 and a second rack 65 respectively meshing with the gear component 63. The first rack 64 and the second rack 65 are arranged facing each other, and the first rack 64 and the second rack 65 are slidably connected to the frame 61. The end of the first rack 64 away from the gear component 63 is fixed to the first lens module 4, and the end of the second rack 65 away from the gear component 63 is fixed to the second lens module 5. The output end of the drive unit 62 drives the gear component 63 to move the first rack 64 and the second rack 65, thereby enabling the first rack 64 and the second rack 65 to move synchronously towards or away from each other, realizing automatic interpupillary distance adjustment of the first lens module 4 and the second lens module 5. This achieves high adjustment accuracy, small size, high reliability, and a good user experience.

[0035] Specifically, the two output racks, first rack 64 and second rack 65, are arranged facing each other, and simultaneously mesh with gear component 63 to achieve transmission. When gear component 63 rotates clockwise, it drives first rack 64 to move linearly to the left, and simultaneously drives second rack 65 to move linearly to the right, reducing one stage of reversing transmission, improving transmission efficiency, and enhancing the consistency of rack push-out force. The vertical arrangement of first rack 64 and second rack 65 in space maximizes space utilization, further simplifies the mechanism, and improves assembly efficiency.

[0036] Preferably, the frame 61 is detachably and fixedly connected to the frame body 1, facilitating the maintenance or replacement of the drive module 6. Specifically, the frame 61 is fixedly connected to one side of the frame body 1 using screws.

[0037] Preferably, the drive unit 62 is a stepper motor, drive motor, etc. In this invention, the drive unit 62 is a stepper motor, and the lens adjustment speed can be controlled by changing the pulse frequency through software, thereby improving the user experience. However, this drive motor is not limited to a stepper motor, and other motor forms such as brushed motors can also be used depending on considerations such as drive and cost requirements.

[0038] In this embodiment, the first rack 64 and the second rack 65 are parallel to each other and perpendicular to the axial direction of the drive unit 62, and the first rack 64 and the second rack 65 move the same amount per unit time. The parallel nature of the gear components 63 enables the drive units of the first rack 64 and the second rack 65 to drive synchronously and at the same speed in opposite directions.

[0039] In this embodiment, the VR glasses 100 further includes a first flexible buffer mechanism 7 and a second flexible buffer mechanism 8 disposed opposite to each other. The end of the first flexible buffer mechanism 7 near the drive module 6 is hinged to the first rack 64, and the end of the first flexible buffer mechanism 7 away from the drive module 6 is fixed to the first lens module 4. The end of the second flexible buffer mechanism 8 near the drive module 6 is hinged to the second rack 65, and the end of the second flexible buffer mechanism 8 away from the drive module 6 is fixed to the second lens module 5. By arranging the teeth of the first rack 64 and the second rack 65 in opposite directions, the left and right rack drive units are driven at equal speeds in opposite directions. The addition of the first flexible buffer mechanism 7 and the second flexible buffer mechanism 8 to the output unit achieves bidirectional buffering of the rack movement. This further makes the operation smoother and gentler, with strong impact resistance and high reliability.

[0040] In this embodiment, the first flexible buffer mechanism 7 includes a first hinge portion 71, a first limiting groove 72 recessed at one end of the first hinge portion 71 away from the first rack 64, a first guide rod 73 disposed in the first limiting groove 72, a first spring 74 and a second spring 75 sleeved on the first guide rod 73, and a first nut 76 fixed at one end of the first guide rod 73 away from the first rack 64; the first guide rod 73 is slidably connected to the first lens module 4, and the first nut 76 is located on the side of the first lens module 4 away from the frame 61; the first spring 74 is located in the first limiting groove 72, and the second spring 75 is located between the first hinge portion 71 and the first lens module 4.

[0041] In this embodiment, the second flexible buffer mechanism 8 includes a second hinge portion 81, a second limiting groove 82 recessed at one end of the second hinge portion 81 away from the second rack 65, a second guide rod 83 disposed in the second limiting groove 82, a third spring 84 and a fourth spring 85 sleeved on the second guide rod 83, and a second nut 86 fixed at one end of the second guide rod 83 away from the second rack 65; the second guide rod 83 is slidably connected to the second lens module 5, and the second nut 86 is located on the side of the second lens module 5 away from the frame 61; the second spring 75 is located in the second limiting groove 82, and the second spring 75 is located between the second hinge portion 81 and the second lens module 5.

[0042] Specifically, by flexibly connecting the first rack 64 and the second rack 65 to the first lens module 4 and the second lens module 5 respectively, and by pre-pressing the first guide rod 73 with the first spring 74 and the second spring 75, when the motor drives the rack to extend, the pressure of the second spring 75 increases and the pressure of the first spring 74 decreases. When the motor drives the rack to retract, the pressure of the first spring 74 increases and the pressure of the second spring 75 decreases, thereby achieving bidirectional buffering of lens movement. The arrangement of the first spring 74 and the second spring 75 not only provides a buffering mechanism for uneven instantaneous output during motor drive, creating a better viewing experience, but also provides a protection mechanism against external forces impacting the gears, reducing the risk of gear tooth deformation. The overall operation is more stable and flexible, with improved impact resistance and reliability.

[0043] Simultaneously, the second guide rod 83 is pre-pressed in by the third spring 84 and the fourth spring 85. When the motor drives the rack to extend, the pressure of the fourth spring 85 increases and the pressure of the third spring 84 decreases. When the motor drives the rack to retract, the pressure of the third spring 84 increases and the pressure of the fourth spring 85 decreases, thereby achieving bidirectional buffering of the lens movement.

[0044] In this embodiment, the first lens module 4 includes a first lens barrel 41 disposed in the first mounting hole 2, a first lens group 42 fixed in the first lens barrel 41, and a first connecting portion 43 protruding from the outer wall of the first lens barrel 41; a first guide hole 431 is formed through the first connecting portion 43, a first guide rod 73 is disposed in the first guide hole 431, a second spring 75 is disposed between the first hinge portion 71 and the first connecting portion 43, and a first nut 76 is disposed on the side of the first connecting portion 43 away from the frame 61 and abuts against the first connecting portion 43;

[0045] The second lens module 5 includes a second lens barrel 51 disposed in the second mounting hole 3, a second lens group 52 fixed in the second lens barrel 51, and a second connecting part 53 protruding from the outer wall of the second lens barrel 51; a second guide hole 531 is formed through the second connecting part 53, a second guide rod 83 is disposed in the second guide hole 531, a fourth spring 85 is disposed between the second hinge part 81 and the second connecting part 53, and a second nut 86 is disposed on the side of the second connecting part 53 away from the frame 61 and abuts against the second connecting part 53.

[0049] In this embodiment, the VR glasses 100 further includes a steel plate 10. The frame body 611 has a first countersunk hole 618 formed through the end of the rotating shaft 631 away from the driving unit 62. The side of the frame body 611 away from the frame body 1 has a recessed mounting groove 617. The steel plate 10 is inserted into the mounting groove 617.

The rotating shaft 631 can be assembled with the frame body 611 via an interference fit and externally enclosed by the steel sheet 10. During operation, the rotating shaft 631 does not rotate with the gear structure 632, completely eliminating the need for bearings 11 to fix both ends of the rotating shaft 631; reducing the friction between the rotating shaft 631 and the bearing 11; reducing parts and assembly costs when the bearing 11 is assembled with the frame body 611; preventing large dimensional tolerances when there are many parts, resulting in high precision and efficiency.
