Description

Technical Field

[0001] The present invention belongs to the technical field of wearable devices, and in particular relates to a pair of glasses based on 3D printing and their use. Background Art

[0002] With the rise of professional sports and the development of technology, sports protective glasses and VR glasses have become commonplace. However, these glasses all have a characteristic: the sponge lining can become very hot and humid after prolonged wear, and the poor air permeability leads to severe sweating around the glasses.

[0003] Currently, protective glasses and VR glasses on the market are primarily lined with sponge, with a fabric exterior. These linings are primarily made of high-density sponge, which offers excellent softness and sealing properties, ensuring a good fit and opacity against the face. However, these materials also suffer from poor breathability, leading to stuffiness and discomfort in the eyes after prolonged wear, and also causing sweat and moisture to accumulate in the eyes.

[0004] For sports protective eyewear, when athletes engage in strenuous exercise, sweat and moisture accumulate in the eyes, potentially causing blurred vision or loss of focus, affecting concentration and reflexes and increasing the risk of accidents. For VR glasses, the accumulation of sweat and moisture after prolonged wear can also have a significant negative impact on the virtual reality experience. Blurred or out-of-focus vision not only reduces immersion but can also cause discomfort such as dizziness and nausea. Furthermore, the accumulation of moisture and sweat can cause odors and bacterial growth in the glasses, increasing the risk of cross-infection. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a pair of glasses based on 3D printing and its use. The purpose of the present invention is to provide a pair of glasses that have good fit and opacity as well as good air permeability and comfort.

[0006] The 3D printing-based glasses provided by the present invention include a frame and lenses installed on the frame, and an inner lining ring is also provided along the frame; the inner lining ring has a flexible surface layer and an elastic support body covered in the surface layer; a plurality of first through holes are provided on the surface layer and located on the inner side of the inner lining ring, and a plurality of second through holes are provided on the surface layer and located on the outer side of the inner lining ring; a plurality of extinction channels are also formed in the elastic support body, one end of the extinction channel is connected to the first through hole, and the other end is connected to the second through hole.

[0007] As a further optimization solution, the extinction channel is a combination of one or more spiral channels, wavy channels, and broken-line channels; the light entering the extinction channel is absorbed once or multiple times by the inner wall of the extinction channel and is weakened to an intensity invisible to the naked eye.

[0008] As a further optimization solution, the extinction channel is a spiral channel with a spiral angle ranging from 360° to 1080°, and the cross-section of the spiral channel is selected from circular, elliptical, and polygonal.

[0009] As a further optimization solution, the extinction channel is a spiral channel with a circular cross-section, a spiral angle in the range of 360° to 1080°, and an aspect ratio in the range of 9 to 35.

[0010] As a further optimization solution, the surface layer, elastic support body and matte channel are integrally formed using 3D printing.

[0011] As a further optimization solution, the elastic support body includes multiple structural nodes and multiple structural rods. Each structural node leads to multiple structural rods in different directions, and the two ends of each structural rod are connected to different structural nodes; the structural nodes and structural rods are arranged and connected in three-dimensional space to form an elastic support body together.

[0012] As a further optimization scheme, the average number of structural rods directly connected to each structural node, the average rod diameter of each structural rod, and the average length of each structural rod are set differently; by setting at least one of the structural parameters differently, the flexibility of the elastic support body facing the human face is greater than the flexibility of the side away from the human face.

[0013] As a further optimization solution, the glasses also have a strap, with both ends of the strap respectively arranged on both sides of the frame, and a tension adjustment buckle is provided on the strap.

[0014] As a further optimization solution, the glasses also have a headband, which is ring-shaped and has a front end connected to the middle of the frame.

[0015] As a further optimization solution, a flexible pad is provided on the part of the headband that contacts the back of the human head.

[0016] The 3D printing-based glasses provided by the present invention can be used as any one or more of VR glasses, ski goggles, mountaineering goggles, cycling goggles, and rock climbing goggles.

[0017] Beneficial effects

[0018] The 3D-printed glasses provided by the present invention can provide a comfortable wearing experience, effectively block external light interference, achieve good air permeability, have wide adaptability, can be personalized in design and production, and have a wide range of usage scenarios.

[0019] Provide comfortable wearing experience: The inner lining ring has a soft surface layer and elastic support body, which can provide good touch and comfort, reduce the pressure and pain of glasses on the face; the inner lining ring also prevents the frame from directly contacting the face, preventing discomfort and scratches.

[0020] Blocking external light interference: The inner lining ring fits well with the skin of the human eye, preventing external light from entering through the gap; in addition, the path and structural design of the extinction channel ensure that the light entering the extinction channel undergoes multiple refractions and absorptions until it reaches a level invisible to the naked eye, effectively blocking external light interference.

[0021] Achieve good breathability: The extinction channel runs through the inner lining ring, which improves the breathability of the glasses and reduces the stuffiness around the eyes through the gas exchange channel.

[0022] Wide adaptability: By adjusting the structural parameters of different parts of the elastic support body, the flexibility of the side facing the human face is made greater than the flexibility of the side away from the human face. This can better adapt to the different shapes and curves of different people's faces and provide a more fitting wearing feel.

[0023] Personalized design and production: The liner ring can be personalized designed and produced using 3D printing technology, providing more market-segmented products based on individual facial shapes and wearing needs.

[0024] Wide range of usage scenarios: The glasses provided can be used as VR glasses, ski goggles, mountaineering goggles, cycling goggles, rock climbing goggles, or any one or more of the following. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1

[0035] like Figure 1 The VR glasses shown in the figure include a frame 1 and a lens 2 mounted on the frame 1. An inner lining ring 3 is provided along the frame 1. The inner lining ring 3 has a flexible surface layer 31 and an elastic support body 32 wrapped in the surface layer 31. The surface layer 31 is as shown in FIG. Figure 2 As shown, the elastic support body 32 is as shown in FIG. Figure 3 and Figure 4 As shown. Among them, the frame 1 is the main structure of the VR glasses, providing the basic framework of the entire glasses, and is also used to fix and support the lens 2. The lens 2 is the imaging part of the VR glasses, which displays the image of the virtual reality world through light or reflection, allowing users to clearly observe and experience the virtual reality content. The lining ring 3 is a flexible pad installed on the frame 1, which contacts the skin of the human eye, provides good touch and comfort, avoids direct contact between the frame 1 and the face, and prevents discomfort and scratches. In addition, the flexible lining ring 3 has a good fit with the skin of the human eye, preventing external light from entering through the gap between the human body and the glasses, and preventing external light from interfering with the user's experience of virtual reality content.

[0036] The surface layer 31 of the lining ring 3 is as follows Figure 2 As shown, a plurality of first through holes 311 are provided on the surface layer 31 and located on the inner side of the inner liner ring 3 , and a plurality of second through holes 312 are provided on the surface layer 31 and located on the outer side of the inner liner ring 3 .

[0037] The elastic support body 32 is as follows Figure 3 and Figure 4As shown, a number of extinction channels 321 are also formed in the elastic support body 32, one end of the extinction channel 321 is connected to the first through hole 311, and the other end is connected to the second through hole 312. The extinction channel 321 includes but is not limited to a combination of one or more connected spiral channels, wavy channels, and zigzag channels; the light entering the extinction channel 321 is absorbed once or multiple times by the inner wall of the extinction channel 321 and is weakened to an intensity that is invisible to the naked eye. The extinction channel 321 is located in the elastic support body 32, connecting the first through hole 311 and the second through hole 312, forming a spiral, wavy, zigzag or a combination thereof gas exchange channel. The light undergoes multiple refractions and absorptions in the channel, and the energy decays rapidly and cannot be emitted from the other end, or the light intensity drops to a level that is invisible to the naked eye. The extinction channel 321 reduces glare by weakening and eliminating the light entering the glasses, providing better visual effects and immersion.

[0038] Furthermore, a light extinction channel 321 runs through the inner lining ring 3. While light cannot pass through, air can still circulate, thus forming a gas exchange channel. Through the light extinction channel 321, air around the eye can circulate and exchange with the external environment, effectively improving the breathability of the glasses and reducing the feeling of stuffiness around the eyes. Moisture generated by the eyes can also be discharged through the light extinction channel 321, preventing it from accumulating on the lens 2, resulting in a better visual effect.

[0039] As described above, the extinction channel 321 includes, but is not limited to, a combination of one or more of a spiral channel, a wavy channel, and a broken line channel. Furthermore, the cross-section of the channel can be selected from a circle, an ellipse, and a polygon. The polygon can be a square, a rectangle, a triangle, a pentagon, a hexagon, a trapezoid, a rhombus, or the like.

[0040] The extinction channel 321 is preferably a spiral channel. There is no turning in the spiral channel, and the air flow resistance in the spiral channel is small, which is conducive to improving air permeability. The spiral channel is conducive to the light undergoing multiple refractions and absorptions in the channel, thereby weakening the intensity of the light so that the light does not emit from the other end of the channel. The spiral angle is preferably in the range of 360°~1080°. When the channel cross-section is circular, the aspect ratio is preferably in the range of 9~35. When the spiral angle is too large and the aspect ratio is too large, the channel path will become longer, reducing the air circulation efficiency; too small a spiral angle and too small an aspect ratio will easily lead to a reduction in the number of refractions of light in the channel, which is not conducive to light blocking.

[0041] Figure 5 、 Figure 6 、 Figure 7 Several different preferred spiral channels are schematically listed, among which, Figure 5 Shown is a spiral channel with a circular cross section and a spiral angle of 360°; Figure 6Shown is a spiral channel with a circular cross section and a spiral angle of 720°; Figure 7 Shown is a variable diameter spiral channel with a regular pentagonal cross section and a spiral angle of 720°.

[0042] like Figure 3 and Figure 4 As shown, the elastic support body 32 includes multiple structural nodes 322 and multiple structural rods 323. Each structural node 322 extends into multiple structural rods 323 in different directions, and each structural rod 323 is connected to different structural nodes 322 at both ends. The structural nodes 322 and structural rods 323 are arranged and connected in three-dimensional space, together forming the elastic support body 32. Through the connection between the multiple structural nodes 322 and structural rods 323, the elastic support body 32 can withstand external strain and force and can return to its original shape after the force is applied. This structural design can effectively absorb and buffer external impact and compression, thereby protecting the glasses and providing a comfortable wearing experience. In addition, the connection between a large number of structural nodes 322 and multiple structural rods 323 can also make the elastic support body 32 more stable and durable, and can withstand long-term use while maintaining its basic overall shape without losing its elasticity.

[0043] The structural parameters of the elastic support body 32 include: the average number of structural rods 323 directly connected to each structural segment 322, the average rod diameter of each structural rod 323, and the average length of each structural rod 323. By setting at least one of these structural parameters differently, the side of the elastic support body 32 facing the human face is more flexible than the side facing away from the human face. The shapes and curves of different human faces vary. By making the side facing the human face more flexible, the frame can better adapt to the curves of the face and provide a more comfortable wearing experience. This can reduce or avoid uncomfortable pressure from the frame on other areas of the face, reducing facial pain or concentrated pressure caused by wearing the glasses for too long. Furthermore, the greater flexibility on the side facing the human face provides better fit and stability. By providing a larger support and contact area on the face, the stability of the glasses can be improved, reducing shaking and sliding during activities, and improving wearing stability and comfort.

[0044] By reducing the number of structural rods 323 directly connected to each structural segment 322, the connection can be weakened, the deformation range of the elastic support body 32 can be strengthened, and thus the flexibility can be improved. By reducing the rod diameter of the structural rod 323, the overall stiffness and bending rigidity can be reduced, thereby improving the flexibility. By increasing the length of the structural rod 323, the overall stiffness can be reduced, the deformability of the elastic support body 32 can be increased, thereby increasing the flexibility. Conversely, by increasing the average number of structural rods 323 directly connected to each structural segment 322, increasing the average rod diameter of each structural rod 323, and reducing the average length of each structural rod 323, the flexibility can be reduced.

[0045] The inner lining ring 3, which comprises a surface layer 31, an elastic support body 32, and a matte channel 321, has a relatively complex spatial structure. This structure can be integrally formed using 3D printing. 3D manufacturing technology offers a high degree of flexibility and design freedom, enabling the manufacture of complex inner lining ring 3 structures. Furthermore, personalized design and production can be tailored to individual facial shapes and eyewear preferences, providing products with a wider range of market segments.

[0046] The material of the inner lining ring 3 is preferably but not limited to thermoplastic polyurethane elastomer. Thermoplastic polyurethane elastomer has the advantages of good elasticity, strong load-bearing capacity, oil resistance, water resistance, mildew resistance, etc., and is convenient for 3D printing processing. Thermoplastic polyurethane elastomer has good elasticity and can produce large deformation under the action of external force and quickly return to its original shape, so it can provide a comfortable wearing experience for the wearer. Its good elastic properties can effectively relieve the pressure and pain of glasses on the face and improve wearing comfort. Thermoplastic polyurethane elastomer has excellent durability and can resist friction in daily use. It also makes the life of the inner lining ring of the glasses longer and can withstand long-term wear and multiple deformations without losing its elasticity and function.

[0047] like Figure 1 As shown, the VR glasses also have a headband 5, which is ring-shaped. The front end of the headband 5 is connected to the middle part of the frame 1. The part of the headband 5 that contacts the back of the human head is provided with a flexible pad 51 to facilitate wearing.

[0048] Example 2

[0049] like Figure 8 The sports goggles shown can be used as ski goggles, mountaineering goggles, cycling goggles, rock climbing goggles, etc.

[0050] Figure 8 The overall structure of the sports goggles is shown, including a frame 1 and a lens 2 mounted on the frame 1. An inner lining ring 3 is provided along the frame 1. The inner lining ring 3 has a flexible surface layer 31 and an elastic support body 32 wrapped in the surface layer 31. The surface layer 31 is as shown in FIG. Figure 9 As shown, the elastic support body 32 is as shown in FIG. Figure 10 and Figure 11 shown.

[0051] from Figure 9 、 Figure 10 and Figure 11 As can be seen, the inner lining ring 3 of the sports goggles is different from the inner lining ring 3 of the VR glasses only in the overall shape, but the structure and arrangement of its surface layer 31, elastic support body 32, extinction channel 321, first through hole 311 and second through hole 312 are consistent with the design of the inner lining ring 3 in the VR glasses, so they will not be repeated.

[0052] like Figure 8 As shown, the sports goggles further include a strap 4 , the two ends of which are respectively arranged on two sides of the frame 1 , and a tension adjustment buckle 41 is provided on the strap 4 .
