Description

Technical Field

[0001] This utility model relates to the field of eyeglass frame technology, and in particular to a novel elastic sunglass frame. Background Technology

[0002] Sunglasses, as an everyday item that combines protection and style, are widely used in outdoor activities to block strong sunlight, filter ultraviolet rays, and protect eye health. As consumers increasingly demand comfort, structural stability, and aesthetic design, the structural design of sunglasses is constantly being improved, especially in the structural innovation of the connection between the temples and the frame, which has become a key aspect of enhancing the user experience.

[0003] Currently, most sunglasses use a hinge structure to connect the temples to the frame. While this structure allows the temples to fold, it suffers from problems such as insufficient fit, easy loosening, and noticeable clamping sensation during wear. To improve the elasticity of the temples' adjustment capabilities, some products have introduced a spring hinge design. By incorporating micro-coil springs within the hinge, the temples have a certain outward elastic expansion capacity, thus adapting to different head shapes and improving wearing stability and comfort. However, this type of spring hinge structure is complex, has many parts, and requires high manufacturing precision, resulting in higher production costs.

[0004] Therefore, to address the aforementioned technical issues, it is necessary to design a sunglasses temple connection structure that is simple in structure, low in cost, has reliable elasticity, and can provide a unique wearing experience. Utility Model Content

[0005] This invention proposes a novel elastic sunshade, which has a simple structure, low cost, reliable elasticity, and provides a unique wearing experience, thus solving the aforementioned problems existing in the use of existing technologies.

[0006] The technical solution of this utility model is implemented as follows: A novel elastic sun frame includes a frame and two temples located on the left and right sides behind the frame. Each side of the frame includes a post, and a hinge seat is fixedly connected to the post. A metal spring is fixedly connected to the temple. The metal spring extends toward the hinge seat and is integrally formed with a connector. The connector is rotatably connected to the hinge seat.

[0007] Preferably, the temple has an assembly gap groove on the inner side of the end near the post head, the assembly gap groove extends through the inner side of the temple and the end facing the post head, the temple has a spring clip fixing opening on the side of the assembly gap groove facing the tail end of the temple, the end of the metal spring clip away from the connector has a fixing piece integrally formed and fixed in the fixing opening, the metal spring clip extends outward from the fixing piece towards the assembly gap groove, and the connector is located outside the assembly gap groove.

[0008] Preferably, the width of the assembly clearance groove is sufficient to allow the hinge seat and connector to enter.

[0009] Preferably, the temple is provided with two screws for fixing the fixing piece in the spring fixing hole.

[0010] Preferably, a structural reinforcement sleeve is fixedly disposed inside the temple and located within the fixing opening. The structural reinforcement sleeve is annularly sleeved outside the fixing piece, and the structural reinforcement sleeve includes a fixing anchor extending toward the outer side of the temple.

[0011] Preferably, the connector has a bearing surface near the end of the frame for abutting against the hinge seat, and the inner side of the connector near the end of the frame has an arc-shaped rounded corner.

[0012] Preferably, the inner side of the end of the temple is provided with several anti-slip textures.

[0013] In summary, the beneficial effects of this utility model are as follows: 1. This invention incorporates a metal spring on the temple, with a connector integrally formed on the spring. The connector is rotatably connected to a hinge seat on the side of the frame. This structure utilizes the elastic deformation capability of the metal spring to provide stable and reliable elastic restoring force during the opening and closing of the temples. When the user wears the sunglasses, the temples can elastically open outward under external force and automatically return to their original position after release, creating a powerful rebound similar to a slingshot, significantly improving the convenience and stability of wearing them. Simultaneously, the simplified structure and reduced number of parts lower production and assembly costs, achieving an optimized balance between performance and cost.

[0014] 2. An assembly clearance groove is provided on the temple, and one end of the metal spring is fixed in the spring fixing hole, while the connector at the other end extends out of the assembly clearance groove and connects to the hinge seat, allowing the metal spring to have free deformation space inside the temple. This design not only effectively avoids interference between the spring and the inner wall of the temple during deformation, but also makes full use of the spatial layout of the temple body, saving overall structural volume and facilitating the miniaturization and lightweight design of sunglasses.

[0015] 3. The width of the assembly gap groove is designed to allow the hinge seat and connector to enter, so that when the temple is bent outward, the connector can move within the gap groove, thereby expanding the maximum unfolding angle of the temple. This structure significantly improves the adaptability of sunglasses to users with different head shapes, especially suitable for those with larger head circumferences or those who require a snug fit, enhancing the product's versatility and comfort.

[0019] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example: like Figures 1 to 6As shown, this utility model discloses a novel elastic sunglass frame, including a frame 1 and two temples 3 located on the left and right sides behind the frame 1. The frame 1 is used to install lenses, and each of its left and right ends is provided with a post 11. A hinge seat 2 is fixedly connected to the post 11. The hinge seat 2 has a shaft hole structure for realizing a rotatable connection with the temple 3. The temple 3 is made of a plastic material with a certain degree of elasticity, such as TR90, nylon composite material or other engineering plastics, which ensures both lightweight and a certain degree of elastic deformation and recovery ability, which helps to improve wearing comfort and the overall resilience of the structure.

[0021] In this embodiment, a metal spring 4 is fixedly connected to the temple 3. The metal spring 4 is made of stainless steel material with excellent elasticity and fatigue strength, such as 301 or 304 stainless steel. It is formed by stamping, bending and heat treatment processes. The metal spring 4 extends toward the hinge seat 2 and is integrally formed with a connector 41. It is rotatably connected to the hinge seat 2 through the connector 41.

[0022] More specifically, an assembly gap groove 31 is provided on the inner side of the temple 3 near the head 11. The assembly gap groove 31 extends through the inner side of the temple 3 and the end facing the head 11. The assembly gap groove 31 extends a certain distance along the length of the temple 3 to form an open receiving space. In addition, a spring clip fixing hole 32 is provided on the side of the assembly gap groove 31 facing the tail end of the temple 3. A fixing piece 42 is integrally formed on the end of the metal spring clip 4 away from the connector 41 and is fixed in the fixing hole. The fixing piece 42 is embedded in the spring clip fixing hole 32 and is locked and fixed from the outside of the temple 3 by two screws 5 to achieve a firm connection. The metal spring clip 4 extends from the fixing piece 42 toward the outside of the assembly gap groove 31. The connector 41 is located outside the assembly gap groove 31. The connector 41 is flat and has a through hole in the middle. It can be rotatably connected to the hinge seat 2 by a shoulder screw 6.

[0023] The width of the assembly gap groove 31 is designed to allow the hinge seat 2 and the connector 41 to enter. In other words, the width of the assembly gap groove 31 is designed to be slightly larger than the overall thickness of the hinge seat 2 and the connector 41, so that the hinge seat 2 and the connector 41 can be partially embedded in the groove during the unfolding of the temple 3, thereby allowing the temple 3 to obtain a larger outward unfolding angle to adapt to the wearing needs of users with different head shapes.

[0024] Furthermore, to enhance the durability of the connection structure, a structural reinforcement sleeve 7 is fixedly installed inside the temple 3, located within the fixing opening. The structural reinforcement sleeve 7 is made of metal or high-strength plastic and is annularly fitted around the fixing piece 42. The structural reinforcement sleeve 7 includes fixing anchor feet 71 extending outward toward the temple 3. The structural reinforcement sleeve 7 and fixing anchor feet 71 are encased in the plastic material during the injection molding of the temple 3, forming a mechanical anchor, which significantly improves the fixing strength of the structural reinforcement sleeve 7 and prevents the fixing piece 42 from pressing on the temple 3 and causing cracking due to excessive outward bending or repeated bending of the temple 3.

[0025] In this invention, the connector 41 has a contact surface 411 near the frame 1 for abutting against the hinge seat 2. When the temple 3 is extended outward to its maximum normal operating angle, the contact surface 411 forms a surface contact with the corresponding side of the hinge seat 2, restricting the temple 3 from continuing to rotate freely. If the temple 3 needs to be further pried open at this time, it must rely on the elastic deformation of the metal spring 4 and the elastic deformation of the plastic temple 3 itself, thereby providing a clear "sense of positioning" and stable clamping force, avoiding structural damage due to excessive opening. At the same time, the inner edge of the connector 41 near the frame 1 is provided with an arc-shaped rounded corner 412. This rounded corner design allows the temple 3 to slide smoothly inward during the retraction process, avoiding interference or jamming with the hinge seat 2, and improving the smoothness of the opening and closing feel.

[0026] In this invention, the inner side of the end of the temple 3 is provided with several anti-slip textures 33. The anti-slip textures 33 can effectively increase the friction between the temple 3 and the skin behind the wearer's ear, preventing the sunglasses from sliding or falling off during exercise, sweating, or bumpy conditions, thus improving the stability and safety of wearing them.

[0027] In practical use, when a user puts the sunglasses on their head, they gently pry open the temples 3 on both sides with their hands. The metal springs 4 then elastically deform, causing the temples 3 to open outwards after overcoming the resistance of the springs. The connecting head 41 slides within the assembly gap groove 31, allowing the hinge seat 2 to enter, thus achieving a large-angle opening. After being released, the metal springs 4 quickly return to their original position due to their elasticity, causing the temples 3 to spring back inwards. Combined with the slight deformation of the plastic temples 3, this creates a powerful "slingshot" clamping effect, ensuring the frame fits securely against the head. This structure not only improves the convenience and comfort of wearing the sunglasses but also features a simple overall structure, low cost, and ease of mass production.
