Description

Technical Field

[0001] This invention relates to the field of eyewear technology, and more particularly to eyewear with a memory metal structure. Background Technology

[0002] Eyeglasses are widely used in daily life.

[0003] For example, Chinese invention patent No. 202320169757.8 discloses a screwless elastic connection structure between the temples of an eyeglass frame, including a frame, temples, an elastomer, and lenses. The elastomer is disposed between the frame's post and the temple, with both ends of the elastomer being detachably fixed to the post and the temple, respectively. The elastomer drives the temple to bend relative to the frame and then return to its original position. Utilizing the material property of the elastomer to freely deform under external force and return to its original shape after the external force disappears, it serves as a connector between the frame post and the temple. It can freely bend relative to the frame with the temple. Whether the temple is folded or unfolded, or even expanded outwards due to different wearers' facial features, the elastomer can deform with the bending of the temple. Then, utilizing its own material properties, the temple returns to its original position after the external force disappears after wearing.

[0004] The aforementioned frame and temples are connected to each other by an elastomer made of TPEE thermoplastic polyester elastomer. If the elasticity of the pure elastomer is too great, it will put too much pressure on the sides of the head when wearing the glasses, resulting in poor wearing comfort. If the elasticity of the elastomer is too small, it will not be able to recover quickly after prolonged wear and will easily deform. Moreover, its main function of deformation is to use its own material properties to return the temples to their original position after the external force disappears after wearing. It has insufficient resistance to compression and is prone to permanent deformation.

[0005] For example, Chinese invention patent No. 202520238809.1 discloses an adjustable eyeglass structure that adapts to facial contours, including a frame, lenses, and temples. The frame includes a first end face facing the wearer's face, a second end face away from the wearer's face, and a bridge portion corresponding to the wearer's nose bridge. The bridge portion is made of shape memory elastomer material, which bends towards either the first or second end face, allowing the frame curvature to adapt to the wearer's facial contours. By using shape memory elastomer material in the bridge portion of the frame, its high elasticity allows the user to adjust the frame curvature to fit the contour curvature around their face and eye sockets. Utilizing its shape memory effect, the frame returns to a pre-set curvature, allowing for multiple adjustments by the user.

[0006] The above-mentioned eyeglass frame uses shape memory elastomer material as the bridge material, and its bending parts are also made of shape memory elastomer material. However, it only has the function of small deformation recovery after adjustment when wearing, and the function of small outward expansion of the temples. It is still easy to be crushed and deformed when subjected to external force stepping or squeezing. Moreover, the structure is more complex, heavy, and has insufficient resistance to compression and is prone to permanent deformation, so it needs to be improved. Summary of the Invention

[0007] This invention aims to provide eyeglasses with a memory metal structure. The main frame and temples are made of transparent nylon TR90. The core innovation lies in achieving an elastic buffer connection between the frame and temples through a sliding connector made of memory metal. At the same time, it is equipped with optimized limiting structure, hinge structure, nose pad and temple end structure. While retaining the lightweight characteristics, it solves the problems of traditional eyeglasses being easily deformed and damaged by pressure / stepping and having insufficient wearing fit.

[0008] This invention provides eyeglasses with a shape memory metal structure, including a frame, lenses mounted on the frame, and temples. The temples are characterized by having a mounting groove at one end, into which a connecting metal is inserted. A first deformation gap is formed at the connection between the frame and the temples. One end of the connecting metal is rotatably connected to the frame, and the other end forms a second deformation gap with the bottom of the mounting groove. The connecting metal is made of shape memory metal, and both the frame and temples are made of transparent nylon TR90. A limiting component is provided on the connecting metal to engage and limit the relative sliding of the temples and the connecting metal. When the compressive force between the temples and the frame exceeds the limiting force of the limiting component, the connecting metal can slide along the mounting groove and partially slide into the second deformation gap.

[0009] Furthermore, a protrusion is provided on the outer side wall of the connecting metal and between the frame and the temple to limit the temple from rotating outward.

[0010] Furthermore, a deformation groove is provided on the outer wall of the connecting metal and at the mounting groove opening. A guide spring part is provided at the groove opening on the side of the deformation groove away from the frame. The guide spring part abuts against the inner groove wall of the mounting groove to assist in guiding the sliding of the connecting metal. A third deformation gap is formed between the guide spring part and the bottom of the deformation groove. A fourth deformation gap is formed between the outer groove opening of the mounting groove and the protrusion.

[0011] Furthermore, the temple is designed to be thin and flat in the middle and thick at both ends, with the thickness at one end near the frame being greater than that at the other end. The outer sidewalls of the temple are set on the same plane, and the inner sidewalls of the temple are concave, forming a curved deformation space.

[0012] Furthermore, the limiting component includes a limiting groove formed on the inner side wall of the connecting metal and a limiting plate provided at the opening of the limiting groove. The limiting groove is L-shaped, and a limiting mating hole is provided on the wall of the mounting groove. The limiting plate is provided with a limiting protrusion that partially engages with the limiting mating hole.

[0013] Furthermore, a rotating hole is provided at the end of the connecting metal away from the temple, and a rotating groove is provided on the frame. The end of the connecting metal is inserted into the rotating groove and positioned by the hinge assembly in conjunction with the rotating hole.

[0014] Furthermore, the hinge assembly includes a fastening tube with an internal threaded hole and a fastening screw. One end of the fastening tube passes through the end of the frame and through the rotating hole, allowing the connecting metal to rotate around the fastening tube. The fastening screw's fastening end is screwed into the internal threaded hole of the fastening tube. The end of the fastening tube away from the internal threaded hole is configured with a non-circular cross-section, and the frame is provided with a non-circular cross-section groove that matches it.

[0015] Furthermore, two nose pad mounting slots are provided opposite each other in the middle of the frame, and silicone airbag nose pads are installed in the two nose pad mounting slots respectively.

[0016] Furthermore, the bottom of the nose pad mounting groove is provided with a through-hole card interface, and the side wall of the silicone airbag nose pad is provided with a card block. The upper and lower side walls of the card block are provided with card block slots. The card block is inserted into the card interface and partially protrudes, and the card interface is engaged between the two card block slots.

[0017] Furthermore, a transverse through groove is provided in the middle of the side wall of the snap-fit ​​block away from the silicone airbag nose pad.

[0018] The aforementioned eyeglasses with a memory metal structure offer the following advantages compared to existing technologies: the connecting metal is made of memory metal; the frame and temples are made of transparent nylon TR90; the nose pads are made of silicone air cushions; the materials are lightweight; the overall structure is simple and easy to install; and when subjected to external force, the frame and temples can deform relative to each other. Due to the materials and structure, when stepped on from above or below, the frame can completely deform towards the temples. The main deformation points are the first deformation gap at the connection between the frame and temples and the second deformation gap at the bottom of the mounting groove. The frame and temples, due to the properties of their materials, can... The system undergoes slight deformation, while the connecting metal undergoes primary deformation. The connecting metal slides along the mounting groove and partially into the second deformation gap, bending at the first deformation gap. Once the external force is removed, the connecting metal, under its restoring force, slides outward from the mounting groove, allowing the frame and temples to return to their original positions. This structural design addresses the structural weaknesses of traditional eyeglasses, such as easy deformation and breakage under external forces, significantly improving durability. The silicone airbag nose pads, combined with the aforementioned structure, achieve a unified look for the entire pair of glasses. Unlike metal-structured nose pads, they are not easily damaged by simple stepping or external forces. Furthermore, the silicone airbag nose pads offer… Effectively distributing the weight of the nose bridge to avoid red marks and pressure indentations from prolonged wear, the nose pads utilize a snap-on installation structure. Assembly and disassembly are completed simply by engaging the snap-fit ​​blocks and interfaces, requiring no screws or tools, making replacement and maintenance convenient. The overall assembly logic of the connection structure is clear, resulting in higher production and assembly efficiency. Furthermore, deformation grooves are provided on the outer wall of the connecting metal, with guide springs at the groove openings. These guide springs, adhering to the inner wall of the mounting groove, assist in guiding the sliding of the connecting metal and forming a third deformation gap with the bottom of the deformation groove. A fourth deformation gap is formed between the outer groove opening of the mounting groove and the protrusion. The third and fourth deformation gaps... The adjustable distance allows the temples to be bent outwards at a certain angle for everyday wear, accommodating users with different head shapes and significantly improving practicality. The main body is made of TR90 material, with memory metal connectors and silicone accessories, resulting in a low overall weight and meeting lightweight wearing requirements. The non-circular cross-section fastening tube hinge structure effectively prevents screws from loosening and hinges from slipping during use, enhancing structural stability over long-term use. The limiting components achieve graded force distribution for normal stability and overload buffering. The structure remains firm and secure during daily wear, while triggering buffer protection under extreme force, balancing daily use strength and impact resistance.

[0019] The beneficial effects of the present invention will be described in detail in the embodiments, thereby making the beneficial effects more obvious. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0022] The terms "first," "second," etc., used in the specification and claims of this invention are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0024] Example 1: like Figures 1-8As shown, a pair of glasses with a memory metal structure includes a frame 1, lenses 2 mounted on the frame 1, and temples 3. In a specific embodiment of the invention, one end of the temple 3 has a mounting groove 31, and a connecting metal 32 is inserted into the mounting groove 31. A first deformation gap 101 is formed at the connection between the frame 1 and the temple 3. One end of the connecting metal 32 is rotatably connected to the frame 1, and a second deformation gap 102 is formed between the other end and the bottom of the mounting groove 31. The connecting metal 32 is made of memory metal, and both the frame 1 and the temple 3 are made of transparent nylon TR90. A limiting component is provided on the connecting metal 32 for engaging and limiting the relative sliding of the temple 3 and the connecting metal 32. When the external compressive force between the temple 3 and the frame 1 exceeds the limiting force of the limiting component, the connecting metal 32 can slide along the mounting groove 31 and partially slide into the second deformation gap 102.

[0025] By adopting the above technical solution, the traditional rigid connection between the frame and temples is replaced with a sliding shape memory metal + double deformation spacing elastic buffer structure. When subjected to extreme external forces such as stepping or strong compression, the connecting metal slides inward along the mounting groove, compressing the second deformation spacing, while bending at the first deformation spacing. This structural deformation absorbs the impact force, preventing the TR90 frame and temples from breaking directly under rigid stress, significantly improving the glasses' damage resistance. Utilizing the shape memory properties of the shape memory metal, after the external force is removed, the connecting metal automatically slides outward to reset itself, causing the frame and temples to return to their original shape, solving the problem of permanent deformation easily caused by external forces in traditional glasses. The shape memory metal is preferably a nickel-titanium shape memory alloy. The main body of the glasses uses a combination of TR90 transparent nylon and shape memory metal connectors. TR90 material itself is lightweight and tough, and together with the shape memory metal, it bears the main deformation force, ensuring impact resistance while maintaining the overall lightweight of the glasses and reducing wearing burden. The limiting component implements a graded force logic that ensures stability under normal conditions and buffers overload. The structure does not slide relative to each other during daily wear and is stable to use. Buffer protection is triggered only when the force exceeds the threshold, balancing the stability of daily use with the impact resistance performance in extreme scenarios.

[0026] In a specific embodiment of the present invention, a protrusion 33 for limiting the outward rotation of the temple 3 is provided on the outer wall of the connecting metal 32 and between the frame 1 and the temple 3.

[0027] By adopting the above technical solution, the maximum angle of outward rotation of the temples is physically limited, preventing excessive outward expansion of the temples during daily wear and adjustment, avoiding the connecting metal from coming out of the mounting groove, and improving the overall structural reliability. The protrusion is directly formed on the connecting metal, eliminating the need for additional parts, not increasing assembly complexity, and resulting in a compact structure.

[0028] In a specific embodiment of the present invention, a deformation groove 34 is provided on the outer wall of the connecting metal 32 and at the opening of the mounting groove 31. A guide spring part 35 is provided at the groove opening on the side of the deformation groove 34 away from the frame 1. The guide spring part 35 abuts against the inner groove wall of the mounting groove 31 to assist in guiding the sliding of the connecting metal 32. A third deformation gap 103 is formed between the guide spring part 35 and the bottom of the deformation groove 34. A fourth deformation gap 104 is formed between the outer groove opening of the mounting groove 31 and the protrusion 33.

[0029] By adopting the above technical solution, the protrusion 33 serves as a reference for the outer deformation of the temple, cooperating with the fourth deformation spacing to provide limiting support for the daily outward expansion deformation of the temple, ensuring the controllability of the outward expansion deformation and avoiding structural failure caused by unrestricted outward expansion. The third and fourth deformation spacings provide dedicated deformation space for the temple to bend outward slightly, allowing it to naturally expand according to the wearer's head circumference during daily wear, without the need for manual forced adjustment of the temple, greatly improving the fit and versatility. The guide spring part is close to the inner wall of the mounting groove, playing a guiding role when the connecting metal slides, avoiding sliding deviation and jamming; after the external force disappears, it can assist the memory metal to rebound and reset, improving the smoothness and accuracy of the reset. The small deformation during daily wear (third and fourth deformation spacings) is separated from the large buffering under extreme external forces (first and second deformation spacings). Daily use only triggers small deformations, ensuring stable wearing clamping force; only under extreme forces is a large stroke buffer triggered, reducing structural fatigue and improving service life.

[0030] In a specific embodiment of the present invention, the temple 3 is configured to be thin and flat in the middle and thick at both ends, and the thickness at one end near the frame 1 is greater than the thickness at the other end. The outer sidewall of the temple 3 is set on the same plane, and the inner sidewall of the temple 3 is concave to form a curved deformation space.

[0031] By adopting the above technical solutions, the thicker design at both ends ensures the structural strength of the temples, with a greater thickness near the frame to meet the high stress requirements of the connection points and improve connection reliability. The flatter design in the middle effectively reduces the overall weight of the temples, achieving lightweight design. The inner curved deformation space provides room for the temples to deform inward under pressure, working in conjunction with the overall cushioning structure to absorb external forces; it also conforms to the side curve of the wearer's head, improving fit and comfort. The outer wall remains on a flat plane, resulting in a smooth and even appearance without any bumps or unevenness, enhancing the product's visual appeal.

[0032] Example 2: The difference from Embodiment 1 is that, in addition to including the structural features of the aforementioned embodiments, in the specific embodiments of the present invention, such as... Figure 6-8As shown, the limiting component includes a limiting groove 49 formed on the inner side wall of the connecting metal 32 and a limiting plate 36 provided at the opening of the limiting groove 49. The limiting groove 49 is L-shaped. The mounting groove 31 has a limiting mating hole 37 on its wall. The limiting plate 36 has a limiting protrusion 38 that partially engages with the limiting mating hole 37.

[0033] By adopting the above technical solution, the limiting protrusion engages with the limiting mating hole, ensuring stable relative position between the temple and the connecting metal under daily wear stress, preventing loosening or shifting and guaranteeing structural stability during wear. When the external force exceeds the limiting clamping force threshold, the limiting protrusion elastically disengages from the mating hole, allowing the connecting metal to slide smoothly along the mounting groove, triggering a buffering mechanism and precisely achieving a graded force effect of stable limiting and overload buffering. The L-shaped limiting groove provides deformation-accommodating space for the limiting plate, resulting in a compact structure. The entire connecting metal 32 is a single integrated structure, making the processing and production of individual components convenient and cost-effective. Furthermore, it facilitates convenient subsequent installation with temples and frames, offering high practicality.

[0034] Example 3: The difference from Embodiment 2 is that, in addition to including the structural features of the aforementioned embodiments, in the specific embodiments of the present invention, such as... Figure 5 and 8 As shown, the end of the connecting metal 32 away from the temple 3 is provided with a rotating hole 39, and the frame 1 is provided with a rotating groove 40. The end of the connecting metal 32 is inserted into the rotating groove 40 and is installed and positioned by the hinge assembly in conjunction with the rotating hole 39.

[0035] The hinges, rotating holes, and rotating slots work together to allow the temples to fold and unfold normally relative to the frame, fulfilling the basic functions of daily storage and wearing. The connecting metal end is inserted into the rotating slot in the frame, employing a concealed connection design for a clean appearance; at the same time, the rotating slot provides circumferential restraint to the connecting metal end, improving the stability of the rotating connection. This rotating connection structure, in conjunction with the overall cushioning mechanism, allows for angular bending between the frame and temples under pressure, working together with the sliding structure to absorb external forces and providing rotational freedom for overall deformation.

[0036] In a specific embodiment of the present invention, the hinge assembly includes a fastening tube 41 with an internal threaded hole and a fastening screw 42. One end of the fastening tube 41 passes through the end of the frame 1 and through the rotating hole 39, so that the connecting metal 32 rotates around the fastening tube 41. The fastening end of the fastening screw 42 is screwed into the internal threaded hole of the fastening tube 41. The end of the fastening tube 41 away from the internal threaded hole is provided with a non-circular cross-section. The frame 1 is provided with a non-circular cross-section groove that matches it.

[0037] By adopting the above technical solution, the non-circular cross-section fastening tube mates with the non-circular groove of the frame, restricting the circumferential rotation of the fastening tube. This prevents the fastening tube from spinning freely when tightening the fastening screws and also prevents the hinges from loosening and the temples from wobbling after long-term use, significantly improving the durability of the connection structure. The non-circular structure has a built-in positioning function, allowing for quick and accurate alignment during assembly, improving production and assembly efficiency and precision. As a fixed rotation axis, the fastening tube has a high surface smoothness, allowing the connecting metal to rotate smoothly around it, ensuring a good feel when opening and closing the temples, while reducing rotational wear and extending service life.

[0038] Example 4: The difference from Embodiment 2 is that, in addition to including the structural features of the aforementioned embodiments, in the specific embodiments of the present invention, such as... Figure 3 and 4 As shown, two nose pad mounting slots 51 are arranged opposite each other in the middle of the frame 1, and silicone airbag nose pads 52 are installed in the two nose pad mounting slots 51 respectively.

[0039] By adopting the above technical solutions, the silicone airbag nose pads can evenly distribute the weight-bearing pressure on the bridge of the nose, preventing red marks and indentations after long-term wear, and significantly improving comfort during extended wear. The silicone material itself has good elastic deformation capabilities, allowing it to deform synchronously with the overall structure when subjected to external forces such as stepping or squeezing, making it less prone to breakage and damage. This adapts to the overall anti-compression structure, enhancing the overall damage resistance of the glasses. The embedded nose pad mounting slot design ensures a smooth and seamless appearance after installation, without protruding metal supports, improving the overall aesthetics of the product.

[0040] In a specific embodiment of the present invention, the bottom of the nose pad mounting groove 51 is provided with a through-hole card interface 53, the side wall of the silicone airbag nose pad 52 is provided with a card block 54, and the upper and lower side walls of the card block 54 are provided with card block slots 56. The card block 54 is inserted into the card interface 53 and partially protrudes, and the card interface is engaged between the two card block slots 56.

[0041] By adopting the above technical solution and using a snap-fit ​​connection structure, the nose pads can be installed and removed simply by plugging and unplugging, eliminating the need for screws, screwdrivers, or other tools. This makes it convenient for users to replace and maintain the nose pads themselves, reducing maintenance costs. The locking blocks and slots on both the top and bottom provide bidirectional restraint, preventing the nose pads from shifting or falling off during use, ensuring a firm and reliable connection even under daily wear. During production and assembly, the nose pads can be directly pressed into place, eliminating the need for screw tightening, simplifying the production process and improving assembly efficiency.

[0042] In a specific embodiment of the present invention, a transverse through groove 55 is provided in the middle of the side wall of the snap-fit ​​block 54 away from the silicone airbag nose pad 52.

[0043] By adopting the above technical solution, the transverse through groove gives the snap-fit ​​block better elastic deformation capability. During installation, the snap-fit ​​block can retract inward under the pressure of the snap-fit ​​interface, making it easier to pass through the interface; after snapping in place, it automatically springs back and locks in place, making assembly easier. The elastic restoring force brought by the through groove allows the snap-fit ​​block and slot to fit more tightly against the edge of the snap-fit ​​interface, improving the tightness of the snap-fit ​​and reducing the risk of the nose pad accidentally falling off.

[0044] Example 5: The difference from Embodiment 1 is that, in addition to including the structural features of the aforementioned embodiments, in the specific embodiments of the present invention, such as... Figure 6 As shown, the temple 3, at the end furthest from the frame 1, has a groove 61. A stainless steel spring 62 is fixedly installed in the groove 61. A silicone temple sleeve 63 is inserted and covered around the stainless steel spring 62. Several interlaced anti-slip grooves 64 are sequentially arranged along the length of the inner wall of the silicone temple sleeve 63. The stainless steel spring 62 is hollow and elliptical, with its inner and outer rings not on the same plane. Figure 1 , Figure 2 As shown, after the silicone temple sleeves 63 are closed or opened, the stainless steel springs 62 remain in two fixed states with left and right rotation. When closed, the two silicone temple sleeves 63 can effectively fit snugly against the wearer's head. The connection between the stainless steel springs 62 and the temples 3 is achieved by inserting the stainless steel springs 62 into the slots 61 of the temples 3 during the high-temperature injection molding process of transparent nylon TR90 for cooling and fixation. After cooling, the outer silicone temple sleeves 63 are then put on. To improve the connection strength between the silicone temple sleeves 63, the temples 3, and the stainless steel springs 62, glue can be applied to the silicone temple sleeves 63 for insertion and bonding fixation.
