Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses manufacturing technology, and specifically refers to a nose pad structure for sunglasses. Background Technology

[0002] Sunglasses, as wearable products that combine functionality and style, are widely used in daily life, outdoor sports, and fashion styling. Their core functions include not only filtering ultraviolet rays and reducing glare to protect the eyes through lenses, but also ensuring wearing comfort and stability through a well-designed structure. As consumers increasingly demand a superior wearing experience, the nose pad structure of sunglasses, as a key component that directly contacts the nose, has become a crucial factor influencing product competitiveness in terms of its fit, support, and long-term wearing comfort.

[0003] However, existing sunglasses generally suffer from limited adaptability and insufficient comfort due to their nose pad structures. For example, traditional one-piece molded nose pads often use a fixed-angle support arm design, which only supports the frame through a single point or small area, resulting in concentrated pressure on the bridge of the nose. This can easily cause pressure marks or pain after prolonged wear. While some detachable nose pads attempt to improve fit by replacing pads of different thicknesses, the connection structure is mostly a simple snap-on or adhesive design, which has poor stability and is prone to falling off due to external force. In addition, some nose pads have smooth surfaces and lack anti-slip design, causing the sunglasses to slip during exercise and requiring frequent adjustments, seriously affecting the user experience. These problems make it difficult for existing sunglasses to meet the personalized needs of users with different nose shapes, especially in situations involving prolonged wear or strenuous exercise, where the conflict between comfort and functionality becomes even more pronounced. Utility Model Content

[0004] This invention achieves detachable connection of the nose pad by extending and bending the nose pad upward to fit the inclined surface of the nose bridge and by using a main and auxiliary joint structure. This alleviates the problem of limited compatibility of traditional nose pads and improves wearing comfort and stability.

[0005] The purpose of this utility model is achieved as follows: a sunglasses nose pad structure, including two connected lens rings, and further comprising:

[0006] Two nose pads are symmetrically arranged inside the lens ring. Each nose pad extends upward from the inner side of the corresponding lens ring to form a main body. The lower end of the main body is bent towards the nasal wing to form a curved part for conforming to the inclined surface of the wearer's nose.

[0007] A main joint structure is provided on the nose pad body, and the main joint structure includes a first joint portion and a second joint portion;

[0008] The nose pad has a secondary engagement structure that mates with the main engagement structure. The nose pad is detachably connected through the engagement of the secondary engagement structure with the first engagement portion and the second engagement portion.

[0009] The present invention is further configured such that the mating surfaces of the main joint structure and the secondary joint structure are interference fit.

[0010] The present invention is further configured such that the first joint portion is a joint protrusion protruding from the top of the nose pad, and the second joint portion is a joint hole penetrating the middle of the nose pad.

[0011] The present invention is further configured such that the sub-joining structure includes a fitting portion adapted to the outer surface contour of the nose support, a groove portion matching the joining protrusion, and a protrusion that can be inserted into the joining hole.

[0012] The present invention is further configured such that the end of the protrusion has an anti-detachment flange to form an elastic buckle structure.

[0013] The present invention is further configured such that the engaging protrusion has a T-shaped structure, and the groove is a groove-shaped structure that matches the engaging protrusion of the T-shaped structure.

[0014] The present invention is further configured such that the lens ring, nose pad and main joint structure are made in one piece.

[0015] The present invention is further provided that the nose contact surface of the nose pad is provided with an anti-slip textured layer.

[0016] By adopting the above technical solution, the beneficial effects that this utility model can achieve are:

[0017] 1. By using the curved part of the nose pad to fit the inclined surface of the nose and the main and secondary joint structure of the detachable nose pad, the nose pad can be replaced according to different nose shapes, which improves the adaptability of sunglasses to a variety of nose shapes.

[0018] 2. The curved part of the nose pad increases the contact area with the bridge of the nose, and together with the nose pad, it disperses the load on the frame, reducing the local pressure concentration caused by traditional single-point support and improving wearing comfort.

[0019] 3. The nose pad is detachable and independent of the nose support body, allowing users to remove it separately for cleaning or replacement. This alleviates the problems of traditional one-piece structures being difficult to clean and prone to sweat residue, thus improving the convenience of hygiene maintenance.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-2 :

[0024] Example 1:

[0025] This embodiment provides a sunglasses nose pad structure, including two connected lens rings 1, and also includes:

[0026] Two nose pads 2 are symmetrically arranged inside the lens ring 1. Each nose pad 2 extends upward from the inner side of the corresponding lens ring 1 to form a main body 20. The lower end of the main body 20 is bent towards the nasal wing to form a curved part 21 for conforming to the inclined surface of the wearer's nose.

[0027] A main joint structure is provided on the nose support 2, and the main joint structure includes a first joint portion 30 and a second joint portion 31.

[0028] The nose pad 4 has a secondary engagement structure 5 that mates with the main engagement structure. The nose pad 4 is detachably connected through the engagement of the secondary engagement structure 5 with the first engagement portion 30 and the second engagement portion 31.

[0029] The lens ring 1 is used to mount the sunglass lenses and is the basic supporting component of the entire nose pad structure. It also provides a mounting position for the nose pad body 2. The two lens rings 1 are symmetrical from left to right and connected by the bridge of the nose. They are usually arc-shaped or rectangular frames with lens slots on the inner edge.

[0030] The nose pad 2, as the main body of the nose pad structure, supports the nose pad 4 and conforms to the wearer's nose, distributing the weight of the sunglasses and reducing pressure on the bridge of the nose. The nose pads 2 are symmetrically positioned inside the left and right lens rings 1, below the sides of the bridge of the nose. The nose pads 2 can be fixed to the lens rings 1 by welding, snap-fitting, or integral molding.

[0031] The nose pad 2 includes a main body 20 and a curved portion 21. The main body 20 is a columnar structure extending upward from the inside of the lens ring 1, providing a base frame for mounting the nose pad 4. The curved portion 21 is an arc-shaped structure that bends at the lower end of the main body 20 toward the nasal wing, and its curvature matches the inclined surface of the nose to form a surface contact to evenly distribute pressure.

[0032] The first joint 30 and the second joint 31 in the main joint structure are used to realize the detachable connection between the nose pad 4 and the nose support 2, provide multi-directional fixing force, and prevent the nose pad 4 from falling off.

[0033] The nose pad 4 comes into direct contact with the wearer's nose, using flexible materials to cushion pressure and an anti-slip design to prevent the sunglasses from slipping. The secondary engagement structure 5 of the nose pad 4 is the core component that enables the detachable connection between the nose pad 4 and the nose support 2. Through precise matching with the main engagement structure of the nose support 2, it ensures that the nose pad 4 is stably fixed during wear, easy to install and remove, and optimizes overall comfort and functionality.

[0034] The lens ring 1 supports the lens and transfers the weight to the nose pad 2, which is symmetrically located on its inner side. The nose pad 2 extends upward from the inner side of the lens ring 1 to form the main body 20. The curved part 21 at its lower end bends towards the nose wing to fit the inclined surface of the nose, dispersing the vertical pressure into surface contact pressure along the nose. The nose pad 4 is detachably connected through the cooperation of the main joint structure on the nose pad 2 and the secondary joint structure 5 on the nose pad 4. The nose pad 4 is made of flexible material, and the surface anti-slip texture enhances the friction with the nose. At the same time, it can keep fit with the dynamic deformation of the nose. Finally, through multi-directional locking and flexible cushioning, the weight of the sunglasses is evenly distributed, improving wearing stability and comfort.

[0035] Example 2:

[0036] This embodiment provides a sunglasses nose pad structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0037] The mating surfaces of the main joint structure and the secondary joint structure 5 are interference fit.

[0038] In this embodiment, the mating surfaces of the main joint structure and the secondary joint structure 5 adopt an interference fit. The purpose is to create an elastic compression effect through the dimensional difference between the two, so that the nose pad 4 and the nose support body 2 can be tightly connected without additional fasteners. On the one hand, the friction generated by the interference fit can effectively prevent the nose pad 4 from loosening and falling off due to daily shaking or external force, thus enhancing the connection stability. On the other hand, by utilizing the elasticity of the materials themselves, such as the deformation ability of silicone and memory resin, the convenient operation of "pressing and joining, pulling and disassembling" can be achieved, avoiding the complicated assembly steps of traditional screws, clips, etc. At the same time, it ensures that reliable locking performance can still be maintained after multiple disassemblies and reassemblies, taking into account practicality and maintenance convenience, and ultimately improving the durability of the product and the user experience.

[0039] Example 3:

[0040] This embodiment provides a sunglasses nose pad structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0041] The first joint 30 is a joint protrusion 300 protruding from the top of the nose pad 2, and the second joint 31 is a joint hole 310 penetrating the middle of the nose pad 2.

[0042] In this embodiment, the first joint 30 is designed as a joint protrusion 300 protruding from the top of the nose pad 2, and the second joint 31 is designed as a joint hole 310 penetrating the middle of the nose pad 2. The purpose is to achieve a multi-directional stable connection of the nose pad 4 through the interlocking of the convex and concave shapes and the layering of the upper and lower parts in position: the top joint protrusion 300 cooperates with the secondary joint structure 5 of the nose pad 4 to restrict vertical movement, and the middle through hole cooperates with the secondary joint structure 5 of the nose pad 4 to restrict left and right displacement. The two form a "vertical + horizontal" two-dimensional locking. During installation, the top protrusion guides the alignment, and the middle through hole completes the locking, ensuring accurate connection direction and balanced force. It can be quickly disassembled and assembled without tools, taking into account both stability and convenience.

[0043] Example 4:

[0044] This embodiment provides a sunglasses nose pad structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0045] The sub-joining structure 5 includes a fitting portion 50 that adapts to the outer surface contour of the nose pad 2, a groove portion 51 that matches the joining protrusion 300, and a protrusion portion 52 that can be inserted into the joining hole 310.

[0046] In this embodiment, the sub-joining structure 5 is provided with a fitting part 50, a groove part 51, and a protrusion part 52. The purpose is to achieve a precise connection and functional enhancement between the nose pad 4 and the nose support body 2 through the coordinated adaptation of multiple components: the fitting part 50 adapts to the outer surface contour of the nose support body 2, tightly wraps the main body part 20 and the curved part 21, eliminates the connection gap to improve the overall integrity and aesthetics, and at the same time helps to distribute pressure; the groove part 51 matches the shape of the engaging protrusion 300 on the top of the nose support body 2 to form a vertical buckle lock to prevent the nose pad 4 from falling off; the protrusion part 52 is inserted into the engaging hole 310 in the middle of the nose support body 2, and is fixed in the horizontal direction by interference fit or elastic buckle. The combination of the three components makes the nose pad 4 stably installed in three-dimensional space, and the curved surface design of the fitting part 50 can enhance the comfort of fitting the nose, while the precise fit between the groove part 51 and the protrusion part 52 ensures the reliability and convenience of the detachable connection.

[0047] Example 5:

[0048] This embodiment provides a sunglasses nose pad structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0049] The end of the protrusion 52 has an anti-detachment flange 520 to form an elastic snap-fit ​​structure.

[0050] In this embodiment, the end of the protrusion 52 is provided with an anti-detachment flange 520 to form an elastic buckle structure. The purpose is to ensure the horizontal connection reliability of the nose pad 4 through a dual mechanism of elastic deformation and geometric limiting: when the protrusion 52 is inserted into the engagement hole 310 of the nose pad body 2, the anti-detachment flange 520 is compressed because its diameter is larger than the hole diameter, generating an elastic restoring force. After being inserted into place, the flange springs open and locks into the hole wall, forming a "barb" effect to prevent the protrusion 52 from coming out. This design does not require additional tools or complicated operations. It can achieve quick locking simply through the elasticity of the material. At the same time, it allows users to apply external force to compress and deform the flange again to remove the nose pad 4. It takes into account both the needs of "stable connection" and "easy disassembly and assembly", avoids the loosening problem caused by long-term use of traditional buckles, and improves the durability of the structure and the user experience.

[0051] Example 6:

[0052] This embodiment provides a sunglasses nose pad structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0053] The engagement protrusion 300 has a T-shaped structure, and the groove portion 51 is a groove-shaped structure that matches the T-shaped engagement protrusion 300.

[0054] In this embodiment, the engaging protrusion 300 is designed as a T-shaped structure and the groove 51 is designed as a matching groove structure. The purpose is to enhance the locking effect of the nose pad 4 in the vertical direction by optimizing the engagement depth: the transverse flange of the T-shaped protrusion and the transverse groove wall of the groove 51 form a "stepped engagement". Compared with the cylindrical protrusion, its horizontal contact area is larger and can withstand stronger upward pull-out force, preventing the nose pad 4 from falling off due to violent movement or external pulling. At the same time, the longitudinal column of the T-shaped structure can guide the groove 51 to be precisely aligned, avoiding misalignment during installation. The opening width and depth of the groove structure are adapted to the size of the T-shaped protrusion, forming a "tight fit" snap-fit ​​relationship, which not only ensures connection stability but also allows disassembly and assembly by moderate external force, such as using the elasticity of the material to make the T-shaped protrusion elastically deform and disengage from the groove. A balance is achieved between structural strength and ease of operation, which is especially suitable for usage scenarios that require high-frequency disassembly and cleaning.

[0055] Example 7:

[0056] This embodiment provides a sunglasses nose pad structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0057] The lens ring 1, nose pad 2, and main joint structure are manufactured in one piece.

[0058] In this embodiment, the lens ring 1, nose pad 2, and main connecting structure are manufactured using an integrated molding method. The purpose is to improve overall performance and manufacturing efficiency through the integrated integration of materials and structure: by molding in one piece with a single mold, the assembly gaps and connecting parts of the traditional split structure are eliminated, avoiding structural failure caused by loose or broken parts, and enhancing the overall strength and impact resistance of the front end of the sunglasses; at the same time, the assembly process is reduced, labor costs and production errors are lowered, and the efficiency of large-scale production is improved; in addition, the integrated molding can precisely control the bending angle of the nose pad 2 and the positional accuracy of the main connecting structure, ensuring the matching accuracy with the nose pad 4 and the secondary connecting structure 5, thereby optimizing the mechanical transmission path during wearing, making the weight distribution more even, and taking into account product durability, production economy and wearing comfort.

[0059] Example 8:

[0060] This embodiment provides a sunglasses nose pad structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0061] The nose pad 4 has an anti-slip textured layer 6 on its nose contact surface.

[0062] In this embodiment, the nose pad 4 has an anti-slip textured layer 6 on its nose contact surface. The purpose is to prevent the sunglasses from slipping due to the wearer's exercise, sweating, or head tilt by increasing surface roughness and contact friction. The wavy, granular, or mesh textured structure can embed into the skin's fine lines to form a mechanical locking effect, while also disrupting the lubricating effect of the water film formed by sweat on the contact surface. Even if the nose sweats, it can still maintain a sufficient coefficient of friction. In addition, the anti-slip texture can disperse local pressure and avoid excessive pressure on the skin in a single area. Combined with the cushioning effect of the flexible material of the nose pad 4, it further improves wearing stability and comfort, making it especially suitable for sports scenarios or long-term wear needs.

[0063] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
