Description

A face mask with a knob adjustment mechanism Technical Field

[0001] This utility model relates to the field of VR mask technology, specifically to a mask with a knob adjustment structure. 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 screens display images for the left and right eyes respectively; the human eye receives this differentiated information and then generates a sense of depth in the brain.

[0003] VR headsets need to be worn on the face, so they are designed with a face mask that comes into contact with the face. This mask typically consists of a soft component that conforms to the shape of the face and a rigid connecting component. Because current face masks usually cannot be adjusted in distance from the VR headset, the distance between the face and the image display components (such as lenses) on the headset cannot be adjusted, affecting the viewer's perception of the image and resulting in a poor user experience. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide a face mask with a knob adjustment structure.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, unless otherwise stated, "a plurality of" means two or more, and "several" means one or more.

[0028] Please refer to Figures 1 and 2. One embodiment of this utility model provides a face mask with a knob adjustment structure, including: an outer shell 10, an inner shell 20, and a knob adjustment structure 30;

[0029] The inner shell 20 is movably connected to the outer shell 10. The inner shell 20 can be connected to the main body of the VR headset, while the outer shell 10 can be connected to software components for face adaptation. The inner shell 20 can move relative to the outer shell 10 along a preset path. When the mask is worn on the user's face, the preset path extends towards the user's face, and the outer shell 10 and the face are in a relatively fixed state. The inner shell 20 moves relative to the outer shell 10 along the preset path to adjust the distance between the inner shell 20 and the outer shell 10, thereby adjusting the distance between the VR headset and the face, and further adjusting the distance between the image display components on the VR headset and the user's eyes.

[0030] The knob adjustment structure 30 includes an adjustment knob 31 and an adjustment screw 32. The adjustment knob 31 is mounted on the outer shell 10, and the adjustment screw 32 is rotatably mounted on the outer shell 10. The adjustment screw 32 extends along a preset path and is threadedly engaged with the inner shell 20. The adjustment knob 31 is driven to the inner shell 20 via the adjustment screw 32. When the adjustment knob 31 rotates, it drives the inner shell 20 to move along the preset path via the adjustment screw 32. The adjustment knob 31 drives the adjustment screw 32 to rotate, which in turn drives the inner shell 20 to move along the adjustment screw 32, thereby adjusting the position of the inner shell 20 relative to the outer shell 10 along the preset path. Users can rotate the adjustment knob 31 to move the inner shell 20 relative to the outer shell 10. The adjustment screw 32 allows the inner shell 20 to be positioned and stopped at any position within its travel range, achieving stepless adjustment. Users can precisely adjust the inner shell 20 to any practical position according to their needs. It has a wide range of applications, can accurately adapt to the needs of different users, and is easy to operate.

[0031] Please refer to Figures 3 to 6. To facilitate the connection between the inner shell 20 and the adjusting screw 32, in some optional embodiments, the inner shell 20 is provided with a plurality of main sliders 21. Each main slider 21 has an internally threaded hole 22. The adjusting screw 32 is threadedly engaged with the internally threaded hole 22, allowing the adjusting screw 32 to engage with the inner shell 20. Positioning the internally threaded hole 22 on the main slider 21 simplifies the structure of the inner shell 20 and improves its stability. The main sliders 21 can be integrally formed on the inner shell 20, or they can be installed on the inner shell 20 using threaded components, snap-fit ​​components, etc.

[0032] In some optional embodiments, the outer shell 10 is provided with a plurality of guide grooves 11 extending along a preset path. The main slider 21 slides in cooperation with the guide grooves 11. The movement of the main slider 21 is guided by the guide grooves 11, thereby improving the stability of the sliding of the main slider 21 and thus improving the stability of the movement of the inner shell 20, and preventing the inner shell 20 from shaking relative to the outer shell 10.

[0033] In some optional embodiments, the housing 10 is provided with a first limiting groove 12. The end of the adjusting knob 31 away from the adjusting screw 32 is rotatably engaged with the first limiting groove 12. The first limiting groove 12 restricts the movement of the adjusting knob 31 in the axial and radial directions of the adjusting screw 32, thereby preventing the adjusting knob 31 from shaking under user operation and causing positional displacement of the adjusting knob 31 or the adjusting screw 32. The housing 10 is provided with a second limiting groove 15. The end of the adjusting screw 32 away from the adjusting knob 31 is rotatably engaged with the second limiting groove 15. The second limiting groove 15 restricts the movement of the adjusting screw 32 in the axial and radial directions. The second limiting groove 15 restricts the movement of the adjusting screw 32, so that the adjusting screw 32 can only rotate within the receiving cavity 13, preventing the adjusting screw 32 from deviating and thus improving the stability of the adjusting screw 32. In this embodiment, one end of the adjusting screw 32 is rotatably engaged with the second limiting groove 15, while the other end of the adjusting screw 32 is connected to the adjusting knob 31. The adjusting screw 32 and the adjusting knob 31 cannot rotate relative to each other. The limiting groove 12's restriction on the adjusting knob 31 also effectively restricts the end of the adjusting screw 32 away from the second limiting groove 15, and the limiting groove 15's restriction on the adjusting screw 32 also effectively restricts the end of the adjusting knob 31 away from the first limiting groove 12. Therefore, the first limiting groove 12 and the second limiting groove 15 can cooperate to stably limit the knob adjusting structure 30 formed by the adjusting screw 32 and the adjusting knob 31, so that the knob adjusting structure 30 can only rotate relative to the circumferential direction of the adjusting screw 32, and cannot be offset in the radial or axial direction of the adjusting screw 32. Of course, in other embodiments, other suitable methods can be used to limit the position of the adjusting knob 31 and the adjusting screw 32, and this example is not limited to this one.

[0034] In some optional embodiments, the outer casing 10 is provided with a receiving cavity 13, and an operation port 131 is provided on one side of the receiving cavity 13. The adjusting screw 32 and the adjusting knob 31 are rotatably disposed within the receiving cavity 13, with part of the adjusting knob 31 protruding from the operation port 131. The receiving cavity 13 can conceal part of the adjusting screw 32 and the adjusting knob 31, improving the overall aesthetics and protecting the adjusting screw 32 and the adjusting knob 31, and also making it convenient for the user to operate the adjusting knob 31 close to the outer casing 10, thus improving the user's operating experience. Of course, in other embodiments, the adjusting screw 32, the adjusting knob 31, and other structures can also be hidden between the inner casing 20 and the outer casing 10, thus eliminating the need for the receiving cavity 13. Alternatively, other suitable installation methods can be used, and this example is not limited to this one.

[0035] In some optional embodiments, the outer shell 10 is provided with a plurality of decorative covers 14, which surround the outer shell 10 to form a receiving cavity 13, thereby facilitating the forming of the receiving cavity 13. The decorative covers 14 can be assembled with the outer shell 10 through threaded parts, snap fasteners and other structures, which facilitates the installation of the adjusting screw 32 and the adjusting knob 31. The operating port 131 is provided on the decorative cover 14, which helps to reduce the structural complexity of the outer shell 10 and facilitates the forming of the outer shell 10.

[0036] In some optional embodiments, the face mask with knob adjustment structure includes two knob adjustment structures 30. The adjustment knobs 31 of the two knob adjustment structures 30 are rotatably disposed on both sides of the outer shell 10. The adjustment screws 32 of the two knob adjustment structures 30 are threadedly connected to both sides of the inner shell 20. In this embodiment, the adjustment screws 32 of the two knob adjustment structures 30 are threadedly engaged with the internal threaded holes 22 on the main sliders 21 on both sides of the inner shell 20. Since the outer shell 10 and the inner shell 20 are relatively wide, the two knob adjustment structures 30 can improve the stability of the movement of the inner shell 20 and the outer shell 10, and also facilitate precise adjustment of the position of the inner shell 20. When the face mask with knob adjustment structure includes two knob adjustment structures 30, guide grooves 11, accommodating cavities 13, and decorative covers 14 are provided on both sides of the outer shell 10, and main sliders 21 are provided on both sides of the inner shell 20, thus correspondingly assembling with the two knob adjustment structures 30.

[0037] In this embodiment, the first limiting groove 12 and the second limiting groove 15 are disposed in the receiving cavity 13.

[0038] The connection method between the inner shell 20 and the outer shell 10 can be designed according to actual needs. For example, in some optional embodiments, the inner shell 20 is provided with a plurality of sliding grooves 23, which extend along a preset path. A protruding sliding portion 24 is provided on the inner side of the sliding groove 23. The outer shell 10 is provided with a plurality of auxiliary sliders 16, which extend into the sliding grooves 23 and engage with the sliding portions 24. The auxiliary sliders 16 can move back and forth along the sliding grooves 23 on the preset path, thereby improving the stability of movement between the inner shell 20 and the outer shell 10 and facilitating the assembly between the outer shell 10 and the inner shell 20. Furthermore, after the auxiliary sliders 16 extend into the sliding grooves 23 and engage with the sliding portions 24, the sliding portions 24 restrict the auxiliary sliders 16 from detaching from the sliding grooves 23. The auxiliary sliders 16 can also move along the sliding portions 24, thus enabling the inner shell 20 to be assembled onto the outer shell 10 while simultaneously allowing the inner shell 20 to move relative to the outer shell 10.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
