Description

Technical Field

[0001] This invention relates to the field of folding rotating shaft technology, specifically a rotating shaft for folding VR glasses. Background Technology

[0002] VR headsets use head-mounted display devices to block out a person's vision and hearing from the outside world, guiding the user to feel as if they are in a virtual environment. The display principle is that the left and right eye screens display images for the left and right eyes respectively. After the human eye receives this information with differences, it generates a sense of three-dimensionality in the brain.

[0003] Currently, VR headsets fall into three main categories: Smartphone-embedded VR headsets are experiential VR products, primarily 3DOF VR. They utilize the user's smartphone, which acts as the processor, display, and gyroscope, while the VR headset itself only provides a convex lens, making these headsets very low-cost. VR head-mounted displays represent the high-end segment of VR headsets. To achieve excellent display effects, they need to connect to a PC (Sony's PSVR connects to a PS4), using the PC's CPU and graphics card for computation. All-in-one VR headsets are models with a built-in display, gyroscope, and computing module. They operate without requiring an external phone and use mobile chips (such as Qualcomm Snapdragon series) for image and positioning calculations. Freed from the constraints of external devices like PCs / PS4s, they are plug-and-play and extremely convenient.

[0004] Both the mobile phone box embedding device and the VR head-mounted display require the use of hinges for connection and installation. However, after long-term and repeated use, the hinges are prone to loosening, reducing their own rotational damping effect. When forcefully connecting the components, collisions and vibrations may occur, causing damage to parts, reducing service life, and affecting the user experience. Therefore, a hinge for folding VR glasses is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a hinge for folding VR glasses to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: It includes a left shaft frame, a right shaft frame rotatably mounted at one end of the left shaft frame, an adjustment mechanism connected to one end of the left shaft frame, mounting frames connected to one side of both the left and right shaft frames, a buffer unit connected to one side of the mounting frame, a positioning unit connected to one side of the left shaft frame, and a reinforcing frame connected to one side of the right shaft frame, with one end of the positioning unit extending into the reinforcing frame;

[0007] The left shaft frame includes a left shaft body, one end of which has a compression groove. A compression spring is connected to one side of the compression groove, and a push plate is connected to one end of the compression spring.

[0008] Preferably, the right shaft frame includes a right shaft body, one end of which has a movable groove, and one end of which is connected to a limiting tube frame. One end of the limiting tube frame is rotatably connected to the left shaft body, and one end of the adjusting mechanism passes through the left shaft body and extends into the movable groove.

[0009] Preferably, the adjusting mechanism includes an adjusting bolt, one end of which passes through the compression spring and the push plate and extends into the movable groove, and is connected to a movable compression plate. A damping rubber sleeve is connected to one side of the movable compression plate, and one end of the damping rubber sleeve abuts against the push plate.

[0010] Preferably, a limiting groove is provided on one side of the movable groove, and limiting blocks are connected to both sides of the movable extrusion plate and are slidably connected to the limiting groove.

[0011] Preferably, both the compression groove and the damping sleeve are tapered, and the diameter of the compression groove is smaller than that of the damping sleeve.

[0012] Preferably, the buffer unit includes a rubber airbag, a hemispherical soft rubber head is connected to one side of the rubber airbag, and an exhaust hole is opened on one side of the rubber airbag.

[0013] Preferably, the positioning unit includes a crossbeam, a connecting rod is connected to one side of the crossbeam, a positioning nut is connected to one end of the connecting rod, and the connecting rod is slidably connected to the reinforcing frame.

[0014] Preferably, a guide hole is provided on one side of the reinforcing frame, and one end of the connecting rod passes through the guide hole and is connected to the positioning nut.

[0015] Preferably, a wear-resistant ring is sleeved and connected between the left shaft bracket and the right shaft bracket.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention uses a mounting bracket to install the rotating shaft at the hinge position between VR glasses components. When fully joined, the hemispherical soft rubber head will preferentially contact the mating surface, thereby compressing the rubber airbag. Due to the small diameter of the exhaust hole, air will be slowly discharged when the rubber airbag is compressed, which has a buffering effect and prevents collisions between the hinged parts. At the same time, when it is necessary to open for maintenance, the left and right shaft brackets can be rotated. Simultaneously, the crossbar rotates with the left shaft bracket, and the rotating connecting rod rotates along the guide hole. When rotated to a suitable angle, the positioning nut is rotated to compress the reinforcing frame, thereby limiting the left shaft bracket through the crossbar, preventing the hinged parts from rotating during maintenance, effectively providing a protective effect, and facilitating maintenance positioning.

[0018] 2. This invention also moves the movable extrusion plate by rotating the adjusting bolt, which in turn pushes the damping sleeve towards the compression groove. Since the size of the compression groove is smaller than the damping sleeve, it gradually compresses the damping sleeve as it moves, increasing the friction between the damping sleeve and the compression groove. Because the movable extrusion plate is connected to the movable groove through the limiting blocks on both sides, the rotation between the right and left shafts will drive the movable extrusion plate to rotate. Due to the pressure on the damping sleeve, the rotational resistance between the right and left shafts is increased. This resistance can be adjusted freely over time to ensure rotational effect while preventing loosening and ensuring stability during use. Attached Figure Description

[0024] 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 some embodiments of the present invention, and not all embodiments. 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.

[0025] Example 1

[0026] Please see Figure 1-2The present invention provides a technical solution: including a left shaft frame 1, a right shaft frame 2 rotatably mounted on one end of the left shaft frame 1, an adjustment mechanism 3 connected to one end of the left shaft frame 1, mounting brackets 4 connected to one side of both the left shaft frame 1 and the right shaft frame 2, a buffer unit 5 connected to one side of the mounting bracket 4, a positioning unit 6 connected to one side of the left shaft frame 1, and a reinforcing frame 7 connected to one side of the right shaft frame 2, with one end of the positioning unit 6 extending into the reinforcing frame 7;

[0027] The left shaft frame 1 includes a left shaft body 11. A compression groove 12 is provided at one end of the left shaft body 11. A compression spring 13 is connected and installed on one side of the compression groove 12. A push plate 14 is connected and installed at one end of the compression spring 13. The compression spring 13 compresses the push plate 14 in both directions, and the bidirectional compression damping sleeve 33 makes full use of the space compression to ensure the friction effect.

[0028] The right shaft frame 2 includes a right shaft body 21. One end of the right shaft body 21 has a movable groove 22. A limiting tube frame 23 is connected and installed at one end of the right shaft body 21. One end of the limiting tube frame 23 is rotatably connected to the left shaft body 11. One end of the adjusting mechanism 3 passes through the left shaft body 11 and extends into the movable groove 22 to ensure the connection effect with the left shaft body 11. At the same time, it facilitates the storage and movement range of the extrusion plate 32 and the damping sleeve 33, thereby ensuring the applicable range of the lifting.

[0029] The adjustment mechanism 3 includes an adjustment bolt 31. One end of the adjustment bolt 31 passes through the compression spring 13 and the push plate 14, and extends into the movable groove 22. A movable compression plate 32 is connected and installed thereon. A damping sleeve 33 is connected and installed on one side of the movable compression plate 32, and one end of the damping sleeve 33 abuts against the push plate 14. A limit groove is provided on one side of the movable groove 22. Limit blocks are connected and installed on both sides of the movable compression plate 32 and are slidably connected to the limit groove. The rotation resistance can be adjusted according to the user's personal preference. It can also be used for a long time, extending its service life. The adjustment is convenient and quick. Rotating the adjustment bolt 31 can increase or decrease the rotation resistance, saving time and effort.

[0030] Both the compression groove 12 and the damping sleeve 33 are tapered, and the diameter of the compression groove 12 is smaller than that of the damping sleeve 33, which facilitates the compression of the damping sleeve 33, increases friction, and creates a damping effect.

[0031] Working principle: When in use, rotating the adjusting bolt 31 drives the moving extrusion plate 32 to move, simultaneously pushing the damping sleeve 33 towards the compression groove 12. Since the size of the compression groove 12 is smaller than that of the damping sleeve 33, it gradually compresses the damping sleeve 33 as it moves, increasing the friction between the damping sleeve 33 and the compression groove 12. Because the moving extrusion plate 32 is connected to the movable groove 22 through the limiting blocks on both sides, the rotation between the right shaft 21 and the left shaft 11 will drive the moving extrusion plate 32 to rotate. Due to the pressure on the damping sleeve 33, the rotational resistance between the right shaft 21 and the left shaft 11 is increased. This resistance can be adjusted automatically over time to ensure the rotational effect while preventing loosening and ensuring stability during use.

[0032] Example 2

[0033] Please see Figure 3-4 The present invention provides a technical solution comprising: a left shaft frame 1, a right shaft frame 2 rotatably mounted at one end of the left shaft frame 1, an adjustment mechanism 3 connected to one end of the left shaft frame 1, mounting brackets 4 connected to one side of both the left shaft frame 1 and the right shaft frame 2, a buffer unit 5 connected to one side of the mounting bracket 4, a positioning unit 6 connected to one side of the left shaft frame 1, and a reinforcing bracket 7 connected to one side of the right shaft frame 2, with one end of the positioning unit 6 extending into the reinforcing bracket 7. The left shaft frame 1 includes a left shaft body 11, a compression groove 12 formed at one end of the left shaft body 11, a compression spring 13 connected to one side of the compression groove 12, and a push plate 14 connected to one end of the compression spring 13.

[0034] The buffer unit 5 includes a rubber airbag 51. A hemispherical soft rubber head 52 is connected and installed on one side of the rubber airbag 51. An exhaust hole 53 is opened on one side of the rubber airbag 51. When the connecting parts are joined by force, it can effectively buffer the connection, avoid collision damage to the connecting parts, and also avoid vibration to each component.

[0035] The positioning unit 6 includes a crossbeam 61, a connecting rod 62 is connected and installed on one side of the crossbeam 61, and a positioning nut 63 is connected and installed at one end of the connecting rod 62. The connecting rod 62 is slidably connected to the reinforcing frame 7, and the positioning can be adjusted at will, which facilitates opening and maintenance and avoids shaking.

[0036] A guide hole 8 is provided on one side of the reinforcing frame 7. One end of the connecting rod 62 passes through the guide hole 8 and is connected to the positioning nut 63 for installation. This facilitates positioning by squeezing the reinforcing frame 77. At the same time, the guide hole 8 satisfies the overall rotation effect of the positioning unit 6.

[0037] A wear-resistant ring 9 is fitted between the left shaft bracket 1 and the right shaft bracket 2 to ensure the stability of the left shaft bracket 1 and the right shaft bracket 2 along the same center line and to ensure the rotation effect.

[0038] Working principle: When in use, the rotating shaft is installed at the hinge position between VR glasses components via the mounting bracket 4. When fully joined, the hemispherical soft rubber head 52 will preferentially contact the mating surface, thereby compressing the rubber airbag 51. Due to the small diameter of the exhaust hole 53, the air in the rubber airbag 51 will be slowly discharged when compressed, which has a buffering effect and prevents collisions between the hinged parts. At the same time, when it is necessary to open for maintenance, the left shaft bracket 1 and the right shaft bracket 2 can be rotated. Simultaneously, the cross bracket 61 rotates with the left shaft bracket 1, and the rotating connecting rod 62 rotates along the guide hole 8. When rotated to a suitable angle, the positioning nut 63 is rotated to compress the reinforcing frame 7, thereby limiting the left shaft bracket 1 through the cross bracket 61, preventing the hinged parts from rotating during maintenance, effectively providing a protective effect, and facilitating maintenance positioning.
