Description

Technical Field

[0001] This invention relates to the technical field of VR glasses manufacturing, and specifically to a nose strip fitting device for VR glasses. Background Technology

[0002] With the rapid development of virtual reality technology, VR glasses, as the core device for immersive experiences, are receiving increasing market attention for their wearing comfort and seal. Nose strips, a key component of VR glasses, are primarily used to fill the gap between the glasses and the bridge of the nose. This not only enhances the seal when wearing the device, reducing light penetration and improving immersion, but also distributes pressure on the bridge of the nose, improving comfort during extended wear. Therefore, the precision and firmness of the nose strip's fit to the bridge of the nose directly impacts the user experience of VR glasses.

[0003] Currently, the application of nose strips for VR glasses largely relies on manual operation. During manual application, operators must manually position the VR glasses and nose strip, then press them together by hand. This method has several drawbacks: First, the positioning accuracy is low; manual visual alignment makes it difficult to ensure the nose strip is precisely positioned on the bridge of the nose, easily leading to misalignment or tilting, affecting the seal and aesthetics. Second, the pressing pressure is uneven; manual pressure is difficult to control and may damage the nose strip. Summary of the Invention

[0004] The purpose of this invention is to provide a nose strip fitting device for VR glasses to overcome the above-mentioned defects in the prior art.

[0005] A nose strip fitting device for VR glasses includes a base, a pressing mechanism and a fitting mechanism. One end of the base is provided with a positioning seat, and the positioning seat is provided with a positioning groove for placing VR glasses. The clamping mechanism is mounted on a fixed plate on the base and is used to fix the VR glasses. The bonding mechanism is located on the base and is used to attach the nose strip to the bridge of the VR glasses and press it down.

[0006] Preferably, the clamping mechanism includes a drive motor, a lifting rod, and a drive rod. The drive motor is mounted on the side of the fixed plate and has a connecting plate on its output shaft. The lifting rod is slidably connected to a guide seat on the side of the fixed plate. One end of the drive rod is hinged to the lifting rod via a pin, and the other end of the drive rod is hinged to the connecting plate via a pin.

[0007] Preferably, the fitting mechanism includes a moving seat, a cylinder and a nose patch seat. The moving seat is slidably connected to the slide rail on the base through a slider. The cylinder is installed on the support plate on the base and the end of its piston rod is connected to the moving seat. The nose patch seat is connected to the moving seat through a fixing seat. The nose patch seat is provided with a placement groove for placing the nose patch. The inside of the nose patch seat is hollow and is provided with a plurality of suction holes. The bottom of the nose patch seat is provided with a fixing column. The lower end of the fixing column is communicated with a vacuum pump through a hose. A plurality of air guide pipes are communicated with the outside of the fixing column. A guiding column is slidably connected in the fixing column. The lower end of the guiding column is connected to a support plate in the fixing column through a spring. The top of the guiding column is connected to a connecting disc through a connecting column. The diameter of the guiding column is larger than that of the connecting column. The connecting disc is provided with a plurality of soft hairs.

[0008] Preferably, a rubber pressing head is provided at the lower end of the lifting rod.

[0009] Preferably, there are two slide rails which are symmetrically arranged on the base.

[0010] Preferably, the moving seat is of an "L" - shaped structure and is symmetrically provided with reinforcing plates thereon.

[0011] Preferably, a plurality of ventilation holes are evenly distributed on the connecting disc.

[0012] Preferably, the air guide pipe is of a "凵" - shaped structure and its upper and lower ends are respectively communicated with the inside of the fixing column.

[0013] Preferably, the fixing plate is of an "L" - shaped structure and is connected to the base through bolts.

[0014] The beneficial effects achieved by the present invention are as follows: 1. In this application, the preliminary positioning of the VR glasses is achieved through the positioning groove of the positioning seat, and precise fixation is completed in cooperation with the pressing mechanism. The pressing mechanism uses a driving motor to drive a link mechanism to convert the rotational motion into the linear lifting motion of the lifting rod, driving the rubber pressing head to press down smoothly, effectively preventing the displacement of the glasses during the fitting process, and laying a foundation for the precise fitting of the nose patch.

[0015] 2. The fitting mechanism of this application drives the moving seat to move smoothly along the slide rail through a cylinder, and uses a vacuum adsorption method to fix the nose patch in the placement groove of the nose patch seat. A negative pressure is formed through the vacuum pump, the hose, the fixing column and the suction holes of the nose patch seat to tightly adsorb the nose patch on the nose patch seat. At the same time, the connecting disc in the nose patch seat is provided with soft hairs. After the vacuum adsorption is closed, the spring drives the soft hairs to move upward, and the nose patch is flexibly contacted and pressed through the soft hairs. It can not only adapt to the curved surface contour of the nose patch to make the nose patch closely fit the surface of the VR glasses, but also avoid damaging the surface of the nose patch during the pressing process, further ensuring the performance of the nose patch.

[0026] like Figures 1-6 As shown, the present invention provides a nose strip fitting device for VR glasses, including a base 1, a pressing mechanism 4 and a fitting mechanism 5. One end of the base 1 is provided with a positioning seat 2, and the positioning seat 2 is provided with a positioning groove 21 for placing VR glasses 6. In addition, the clamping mechanism 4 is mounted on the fixing plate 3 on the base 1 and is used to fix the VR glasses 6. The clamping mechanism 4 includes a drive motor 41, a lifting rod 43 and a drive rod 45. The fixing plate 3 has an "L" shaped structure and is connected to the base 1 by bolts. The drive motor 41 is mounted on the side of the fixing plate 3 and has a connecting plate 42 on its output shaft. The lifting rod 43 is slidably connected to the guide seat 44 on the side of the fixing plate 3. The lower end of the lifting rod 43 is provided with a rubber pressure head 431, which can protect the surface of the VR glasses 6 from scratches and increase the contact area through deformation to provide a more stable clamping force and prevent the glasses from moving during the fitting process. One end of the drive rod 45 is hinged to the lifting rod 43 by a pin, and the other end of the drive rod 45 is hinged to the connecting plate 42 by a pin. In addition, by driving the motor and using the linkage mechanism composed of the connecting plate 42, the drive rod 45 and the lifting rod 43, the rotational motion of the drive motor 41 can be converted into the linear lifting motion of the lifting rod 43, thereby driving the pressing head to press down or lift up smoothly, realizing the pressing and releasing of the VR glasses 6. However, the bonding mechanism 5 is located on the base 1 and is used to attach the nose strip to the bridge of the nose 61 of the VR glasses 6 and press it down. The bonding mechanism 5 includes a movable seat 51, a cylinder 52 and a nose strip seat 53. The movable seat 51 is slidably connected to the slide rails 511 on both sides of the base 1 by a slider. The movable seat 51 has an "L" shaped structure and is symmetrically provided with reinforcing plates, which enhances the structural strength and rigidity of the movable seat 51. In addition, the cylinder 52 is mounted on the support plate 521 on the base 1 and its piston rod end is connected to the movable seat 51. The nose strip holder 53 is connected to the movable seat 51 through the fixed seat 531. The nose strip holder 53 is provided with a placement groove 533 for placing nose strips. The nose strip holder 53 is hollow inside and is provided with several suction holes 532. The bottom of the nose strip holder 53 is provided with a fixed post 54. The lower end of the fixed post 54 is connected to the vacuum pump through a hose 541. In addition, the outer side of the fixed column 54 is connected to several air guide tubes 542. The air guide tubes 542 have a "U" shaped structure and their upper and lower ends are respectively connected to the interior of the fixed column 54. A guide column 55 is slidably connected in the fixed column 54. The lower end of the guide column 55 is connected to the support plate 552 in the fixed column 54 through a spring 551. The top of the guide column 55 is connected to the connecting plate 57 through a connecting column 56. The diameter of the guide column 55 is larger than the diameter of the connecting column 56. The connecting plate 57 is provided with several soft bristles 572. Several ventilation holes 571 are evenly distributed on the connecting plate 57 to facilitate better air intake through the air intake hole 532 of the nose strip seat 53 during negative pressure adsorption. The nose strip is fixed by vacuum adsorption to avoid damage to the adhesive backing, and the nose strip is pressed by the soft adhesive 572. Detailed implementation methods and principles: During operation, the operator places the VR glasses 6 to be fitted with the nose strip into the positioning slot 21, then starts the drive motor 41. The output shaft of the drive motor 41 drives the connecting plate 42 to rotate. The rotation of the connecting plate 42 is converted into the movement of the lifting rod 43 along the guide seat 44 through the drive rod 45. The rubber pressure head 431 at the lower end of the lifting rod 43 gradually approaches the VR glasses 6 and applies appropriate pressure to fix the VR glasses 6 in the positioning slot 21. Then, place the nose strip in the placement slot 533 of the nose strip holder 53 with the adhesive side of the nose strip facing upward. Then, start the vacuum pump and suck air into the fixing post 54 through the hose 541. Then, drive the guide post 55 to move downward, so that the connecting post 56 faces the upper end of the air duct 542, thereby opening the upper end of the air duct 542 that was blocked by the guide post 55. The spring 551 is compressed. The compressed spring 551 also serves to limit the position of the lower end of the guide post 55. At this time, the lower end of the air duct 542 remains in the original open state, and the nose strip is tightly adsorbed onto the nose strip holder 53 through the air suction hole 532 of the nose strip holder 53. Next, cylinder 52 is activated. The piston rod of cylinder 52 extends and pushes the moving seat 51 to move along the slide rail 511 toward the VR glasses 6, causing the nose strip holder 53 on the nose strip holder 53 to move synchronously until the nose strip adsorbed on the nose strip holder 53 is precisely aligned with the nose bridge fitting position of the VR glasses 6. Cylinder 52 stops moving, the moving seat 51 remains in the positioning state, and the nose strip is attached to the nose bridge fitting position of the VR glasses 6. Then, the vacuum pump is turned off, the negative pressure inside the nose strip holder 53 disappears, releasing the adsorption effect on the nose strip. Under the elastic force of the spring 551, the guide post 55 moves upward along the fixed post 54, and the upper end of the air duct 542 is blocked by the guide post 55. At this time, the lower end of the air duct 542 remains open, so that the soft bristles 572 on the connecting plate 57 continue to move along the air inlet 532 of the nose strip holder 53. The flexible contact of the soft bristles 572 can adapt to the curved contour of the nose strip. The soft bristles 572 press the inside of the nose strip, so that the nose strip is pressed on the bridge of the nose of the VR glasses 6.

[0027] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
