Eyeglass nose pad and eyeglasses

Abstract

This invention discloses a nose pad for eyeglasses and eyeglasses, relating to the field of eyeglasses technology. The nose pad comprises a flexible body, which includes two separately arranged flexible shells along its thickness direction. The two flexible shells are an inner contact shell and an outer support shell, respectively. The inner contact shell and the outer support shell are connected and enclosed to form a cavity, which is filled with a cushioning material. The side of the inner contact shell facing away from the outer support shell is used for contact with the wearer's skin. The technical solution of this invention uses two separately arranged flexible shells combined to form a flexible body, with a cavity formed between the two shells and filled with a cushioning material. This allows the flexible body to effectively distribute the pressure of the nose pad on the bridge of the nose, reducing local pressure and the hardness of the nose pad. This avoids the pain and discomfort caused by excessive hardness in traditional nose pads, improving comfort during long-term wear. Simultaneously, the nose pad can deform appropriately during wear, automatically conforming to different nose shapes and adapting to different individual needs.

Description

Technical Field

[0001] This invention relates to the field of eyewear technology, and in particular to an eyeglass nose pad and eyeglasses. Background Technology

[0002] Glasses have become an essential daily necessity for most consumers, and with technological advancements, smart glasses, such as AR glasses, are gradually entering the daily lives of ordinary users, becoming the next generation of smart terminals after smartphones. Thanks to progress in optical displays, artificial intelligence, and 5G communication, AR glasses are constantly being optimized in terms of weight, battery life, and interaction methods, enabling them to demonstrate broader application value in scenarios such as social interaction, entertainment, navigation, and office work.

[0003] Currently, some glasses, such as AR glasses, are quite heavy. In order to provide better support and prevent deformation after prolonged wear, the nose pads of AR glasses on the market are often designed to provide better support. However, in order to achieve better support, the nose pads are usually quite hard, resulting in poor comfort. This causes the nose pads to press on the user's bridge of the nose, which can make the user feel extremely uncomfortable during long-term wear, and may even cause nasal pain. Furthermore, they cannot well adapt to the different wearing needs of different individuals. Summary of the Invention

[0004] The main objective of this invention is to provide a nose pad for eyeglasses and eyeglasses in order to solve the problems of high rigidity, poor comfort, and inability to adapt to the different needs of individuals in the prior art.

[0005] To achieve the above objectives, the present invention proposes a nose pad for eyeglasses, which includes a flexible support body. The flexible support body includes two separately arranged flexible shells along its thickness direction. The two flexible shells are an inner contact shell and an outer support shell, respectively. The inner contact shell and the outer support shell are connected and enclosed to form a cavity. The cavity is filled with a cushioning material. The side of the inner contact shell facing away from the outer support shell is used to contact the wearer's body surface.

[0006] In one embodiment, the flexible support body includes a connecting portion and two contact portions along its extending direction, wherein the two contact portions are spaced apart and connected to each other by the connecting portion, the two contact portions and the connecting portion form a wearing space with a wearing opening on one side, the wearing opening is disposed opposite to the connecting portion, and the flexible support body is connected to the frame of the glasses by a bracket.

[0007] In one embodiment, the connecting portion is U-shaped, and the two ends of the connecting portion are connecting ends. The two contact portions are respectively connected to the two connecting ends, and each contact portion extends from the connecting end toward the frame of the glasses away from the glasses.

[0008] In one embodiment, the inner contact shell includes an inner plate and an inner flange, the inner flange surrounding the outer periphery of the inner plate and bending from the outer periphery edge of the inner plate toward the outer support shell to form an inner groove with the inner plate;

[0009] The outer support shell includes an outer plate and an outer flange. The outer flange surrounds the outer periphery of the outer plate and bends from the outer periphery edge of the outer plate toward the inner contact shell to form an outer groove with the outer plate.

[0010] The outer folded edge is connected to the inner folded edge so that the inner groove and the outer groove form the cavity.

[0011] In one embodiment, the flexible nose pad includes two flexible support bodies spaced apart, forming a wearing space with a wearing opening on one side between the two flexible support bodies, and the two flexible support bodies are connected by a bracket, with the wearing opening and the bracket being disposed opposite to each other.

[0012] In one embodiment, each inner contact shell forms a cavity with an opening on one side, and the edge of each inner contact shell corresponding to the opening is bent toward the corresponding outer support shell to form a plug-in portion. Each outer support shell protrudes toward the corresponding inner contact shell to form a plug-in block. The plug-in block and the plug-in portion are plugged in to connect the outer support shell and the inner contact shell and seal the opening.

[0013] In one embodiment, the support includes two spaced-apart reinforcing sections connected by a connecting section. The two reinforcing sections are respectively connected to opposite sides of the flexible support body, and the connecting section is used to connect to the frame of the glasses.

[0014] In one embodiment, the bracket and the outer support shell are integrally injection molded; or,

[0015] The bracket and the outer support shell are separate, and the two reinforcing sections are respectively connected to the opposite sides of the flexible support.

[0016] In one embodiment, the cavity extends along the extending direction of the flexible support and matches the shape of the flexible support; the cushioning material is air filling the cavity; or,

[0017] The buffer is a silica gel, and a gap is formed between the silica gel and the cavity wall.

[0018] The present invention also proposes a pair of eyeglasses, the eyeglasses comprising a frame and the aforementioned nose pads, the nose pads being connected to the frame.

[0019] In the technical solution of this invention, the nose pads of the glasses are formed by combining two separate flexible shells to form a flexible support body. The two flexible shells form a cavity and are filled with a buffer material, which enables the flexible support body to effectively distribute the pressure of the nose pads on the bridge of the nose, reduce local pressure and nose pad hardness, avoid the pain and discomfort caused by excessive hardness of traditional nose pads, improve the comfort of wearing for a long time, and at the same time enable the nose pads to deform appropriately during wearing, automatically conform to different nose shapes, improve the personalized adaptability of wearing, and can adapt to different individual differences.

[0034] Some existing glasses, such as AR glasses, are relatively heavy. In order to provide better support and prevent deformation after prolonged wear, the nose pads of AR glasses on the market are often designed to provide better support. However, in order to achieve better support, the nose pads are usually quite hard, resulting in poor comfort. This causes the nose pads to press on the user's bridge of the nose, which can make the user feel extremely uncomfortable during long-term wear, and may even cause nasal pain. Furthermore, they cannot well adapt to the different wearing needs of different individuals.

[0035] To address the above problems, this invention proposes a nose pad for eyeglasses 100.

[0036] Please combine Figures 1 to 4 The nose pad 100 of the glasses in this embodiment includes a flexible support body 1. The flexible support body 1 includes two flexible shells 11 that are separately arranged along its thickness direction. The two flexible shells 11 are an inner contact shell 12 and an outer support shell 13, respectively. The inner contact shell 12 and the outer support shell 13 are connected and enclosed to form a cavity 14. The cavity 14 is filled with a buffer material 141. The side of the inner contact shell 12 that is away from the outer support shell 13 is used to contact the wearer's body surface.

[0037] In the technical solution of the present invention, the nose pad 100 of the glasses is formed by combining two separately set flexible shells 11 to form a flexible support body 1. The two flexible shells form a cavity 14 and the cavity 14 is filled with a buffer material 141, so that the flexible support body 1 can effectively disperse the pressure of the nose pad on the bridge of the nose, reduce the local pressure and the hardness of the nose pad, avoid the pain and discomfort caused by the excessive hardness of traditional nose pads, improve the comfort of wearing for a long time, and at the same time enable the nose pad to deform appropriately when worn, automatically fit different nose shapes, improve the personalized adaptability of wearing, and can adapt to different individual differences.

[0038] In one embodiment, the flexible support body 1 includes a connecting portion 15 and two contact portions 16 along its extending direction. The two contact portions 16 are spaced apart and connected by the connecting portion 15. The two contact portions 16 and the connecting portion 15 form a wearing space 17 with a wearing opening 171 on one side. The wearing opening 171 is opposite to the connecting portion 15, and the flexible support body 1 is connected to the frame of the glasses by a bracket 2.

[0039] Two contact portions 16 abut against the sides of the wearer's nose bridge to provide support, and the two contact portions 16 are connected by a connecting portion 15, which improves the support stability of the nose pad and also increases its strength. The contact portions 16 and the connecting portion 15 both contact the nose bridge on the side facing the nose bridge, thereby increasing the contact area between the nose pad and the wearer's body surface, thus making the pressure distribution more even and avoiding discomfort and pressure caused by localized force, thereby improving the comfort of the nose pad. At the same time, the larger contact area can bring better fit and stronger stability, preventing shaking or slipping during use.

[0040] Furthermore, the connecting portion 15 is U-shaped, and the two ends of the connecting portion 15 are connecting ends. The two contact portions 16 are connected to the two connecting ends respectively, and each contact portion 16 extends from the connecting end toward the direction away from the frame of the glasses.

[0041] Because the U-shaped connecting part 15 and the contact part 16 have a smooth transition, they can fit more closely to the wearer's nose bridge when worn, without any protrusions or other structures that would reduce user comfort. At the same time, the U-shaped connecting part 15 provides a certain amount of elastic adjustment space, and the nose pad can be adjusted at an appropriate angle according to the shape of the wearer's nose bridge, so that the contact surface fits the nose bridge more closely, effectively reducing local pressure and improving comfort. The contact part 16 extends away from the frame of the glasses, that is, the contact part 16 extends towards the nose bridge, increasing the contact area between the contact part 16 and the nose bridge, making the pressure distribution more even, avoiding discomfort and pressure caused by local force, thereby improving the comfort of the nose pad.

[0042] Please combine Figures 2 to 4 In one embodiment, the inner contact shell 12 includes an inner plate 121 and an inner folded edge 122. The inner folded edge 122 surrounds the outer periphery of the inner plate 121 and bends from the outer periphery edge of the inner plate 121 toward the outer support shell 13 to form an inner groove 123 with the inner plate 121. The outer support shell 13 includes an outer plate 131 and an outer folded edge 132. The outer folded edge 132 surrounds the outer periphery of the outer plate 131 and bends from the outer periphery edge of the outer plate 131 toward the inner contact shell 12 to form an outer groove 133 with the outer plate 131. The outer folded edge 132 is connected to the inner folded edge 122 so that the inner groove 123 and the outer groove 133 form a cavity 14.

[0043] The inner plate 121 and the inner folded edge 122 form an inner groove 123, and the outer plate 131 and the outer folded edge 132 form an outer groove 133. The inner groove 123 and the outer groove 133 form a cavity 14, so that the shape and extension direction of the cavity 14 are the same as the extension direction of the flexible support body 1. At the same time, the contact part 16 and the connecting part 15 of the flexible nose pad are in contact with the bridge of the nose, that is, the contact part 16 and the connecting part 15 are both formed with cavities 14, so that the flexible cushioning effect of the flexible support body 1 can evenly cover the entire contact area, making the force more balanced, thereby improving the comfort of wearing for a long time. The inner contact shell 12 and the outer support shell 13 are hollow, reducing the solid part of the flexible support body 1, making it lighter, reducing the overall weight of the nose pad, and relieving the burden on the bridge of the nose.

[0044] In one embodiment, the inner folded edge 122 is inclined relative to the inner plate 121, so that the inner groove 123 gradually expands away from the inner plate 121; the outer folded edge 132 is inclined relative to the outer plate 131, so that the outer groove 133 gradually expands away from the outer plate 131. The inclined design of the inner folded edge 122 and the outer folded edge 132 creates an inclination angle in the structure, changing the direction of force. When the buffer 141 in the cavity 14 is compressed and a reaction force is applied to the cavity wall of the cavity 14, the inclined edges help to disperse the force, making the force distribution more uniform and preventing the flexible support 1 from being damaged or leaking due to excessive force.

[0045] In one embodiment, a seam 18 is formed at the connection between the inner contact shell 12 and the outer support shell 13. The two interfaces of the seam 18 are staggered to make the seam 18 S-shaped, thereby increasing the contact area at the connection between the inner contact shell 12 and the outer support shell 13, and improving the connection strength and durability. Specifically, the inner contact shell 12 and the outer support shell 13 are bonded together in the seam 18 by an adhesive.

[0046] Please combine Figure 6 and Figure 7 In one embodiment, the flexible nose pad includes two flexible support bodies 1 spaced apart, forming a wearing space 17 with a wearing opening 171 on one side between the two flexible support bodies 1, and the two flexible support bodies 1 are connected by a bracket 2, with the wearing opening 171 and the bracket 2 being disposed opposite to each other.

[0047] Furthermore, each inner contact shell 12 forms a cavity 14 with an opening on one side, and the edge of each inner contact shell 12 at the corresponding opening is bent toward the corresponding outer support shell 13 to form a plug-in portion 124. Each outer support shell 13 protrudes toward the corresponding inner contact shell 12 to form a plug-in block 134. The plug-in block 134 and the plug-in portion 124 are plugged into each other to connect the outer support shell 13 and the inner contact shell 12 and seal the opening.

[0048] Two flexible support bodies 1 abut against both sides of the bridge of the nose. The separate design of the two flexible support bodies 1 reduces the material required, lowering manufacturing difficulty and cost. The insertion of the outer support shell 13's connector 134 into the inner contact shell 12's connector 124 ensures a more secure and stable connection between the inner contact shell 12 and the outer support shell 13, reducing loosening or deformation under stress and improving overall strength. Furthermore, the separate design of the two flexible support bodies 1 allows for individual fabrication, replacement, and maintenance, significantly reducing production and maintenance costs.

[0049] In one embodiment, the support 2 includes two reinforcing sections 21 spaced apart and connected by a connecting section 22. The two reinforcing sections 21 are respectively connected to opposite sides of the flexible support body 1, and the connecting section 22 is used to connect to the frame of the glasses.

[0050] The support 2 is made of rigid material, making its structure more stable than a purely flexible nose pad. It can withstand greater weight, preventing the AR glasses from deforming or slipping during wear, thus improving overall stability. It also ensures the nose pad maintains its shape even with prolonged wear, extending its lifespan. Two reinforcing sections 21 are connected to opposite sides of the flexible support 1, providing additional support and preventing it from bending or collapsing under pressure, further reducing the decrease in comfort caused by pressure deformation of the nose pad.

[0051] It should be noted that when there is only one flexible support body 1, that is, when the flexible support body 1 includes a connecting part 15 and two contact parts 16 along its extension direction, the two reinforcing sections 21 of the bracket 2 are respectively connected to the two contact parts 16, and are connected on the side of each contact part 16 away from the wearing space 17; when there are two flexible support bodies 1, the two reinforcing sections 21 are respectively connected to the outer support shells 13 of the two flexible support bodies 1.

[0052] Please combine Figure 1 and Figure 4 In one embodiment, the bracket 2 and the outer support shell 13 are integrally injection molded. The integral molding of the bracket 2 and the outer support shell 13 through the injection molding process makes the bracket 2 located inside the outer support shell 13, reducing the possibility of loosening, deformation or breakage between the bracket 2 and the outer support shell 13, so that the nose pad remains stable during long-term use and improves the wearing stability of AR glasses.

[0053] Please combine Figure 5 and Figure 6 In another embodiment, the bracket 2 and the outer support shell 13 are separately configured, and the two reinforcing sections 21 are respectively connected to opposite sides of the flexible support body 1. The separate configuration of the bracket 2 and the outer support shell 13 reduces the manufacturing difficulty and simplifies the manufacturing process compared to integral injection molding. Furthermore, it makes subsequent replacement of the nose pad more convenient, as the bracket 2 and the outer support shell 13 can be replaced independently. If the user needs to replace the nose pad with one of different materials or hardness (such as soft silicone, memory foam, etc.), only the outer support shell 13 needs to be replaced, without replacing the entire nose pad assembly, thus improving the product's maintainability and expandability.

[0054] In one embodiment, the cavity 14 extends along the extension direction of the flexible support 1 and matches the shape of the flexible support 1; the buffer 141 is air filling the cavity 14; or, the buffer 141 is silicone gel, and a gap 142 is formed between the silicone gel and the cavity wall of the cavity 14.

[0055] The cavity 14 extends along the extension direction of the flexible support 1 and matches the shape of the flexible support 1, making the cavity 14 larger and covering the area in contact with the bridge of the nose. This allows the contact area between the flexible support 1 and the bridge of the nose to be flexibly deformable, enabling the nose pad to better adapt to the user's nose shape and enhancing the fit during wear. Simultaneously, the flexibility of all contact points between the bridge of the nose and the nose pad effectively reduces discomfort caused by concentrated local pressure. The filling of the cushioning material 141 gives the cavity 14 a certain degree of elasticity and deformability. During prolonged use, the cushioning material 141 effectively absorbs pressure generated by wearing activities or impacts, preventing the nose pad from deforming or wearing down, thereby improving overall durability. Furthermore, the degree to which the cushioning material 141 fills the cavity 14 determines the overall flexibility of the nose pad; the size of the gap 142 formed between the cushioning material 141 and the cavity wall can be selected according to needs, either completely filling the cavity 14.

[0056] Air, acting as a cushioning material 141, can effectively adapt to the wearer's nose shape and external forces by changing its volume, creating a cushion-like effect. Air can fine-tune and alleviate applied pressure within the cavity 14, thereby reducing the pressure of the nose bridge on the nose and providing greater comfort, especially suitable for prolonged wear. The density of the air within the cavity 14 can be adjusted according to actual needs, thus changing the firmness of the flexible support 1. Silicone gel has excellent softness and elasticity, adapting to changes in the shape of the nose bridge during prolonged use and effectively dispersing pressure. The silicone gel cushioning material 141 can better adapt to head movements and environmental changes, reducing discomfort. When the cushioning material 141 is silicone gel, it is not necessary to completely fill the cavity 14, providing some deformation space for the silicone gel and preventing damage under pressure.

[0057] This invention also proposes a pair of eyeglasses, comprising a frame and the aforementioned nose pad 100, the nose pad being mounted on the frame. The specific structure of the nose pad 100 is as described in the above embodiments. Since this pair of eyeglasses adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here. It should be noted that although this invention is designed for the high weight of smart glasses such as AR glasses, it can still be applied to conventional ordinary eyeglasses, such as myopia glasses and reading glasses, and can also provide better flexibility.

[0058] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
