Abstract
Description
Technical Field
[0001] This utility model belongs to the field of eyeglasses manufacturing technology, and specifically refers to a pressure-relieving eyeglass frame. Background Technology
[0002] Eyeglass frames are common devices used to fix lenses and fit the human face, and are widely used in vision correction, protection, and decoration. The hinge between the frame and temples is the core structure of the eyeglass frame. It not only needs to realize the opening and closing function of the temples, but also needs to be reasonably designed to balance wearing stability and comfort. Especially in scenarios such as sports and long-term office work, the performance of the hinge directly affects the user experience.
[0003] Existing eyeglass frame hinges have significant shortcomings: First, the temple opening angle is generally limited, with most products having a maximum opening angle of no more than 90°. This results in strong pressure on the temples for users with larger heads or those experiencing slight head swelling during exercise, sometimes making the frames unwearable due to the inability to fully open. Second, traditional hinges often employ rigid metal linkage structures, lacking elastic cushioning design. The temples open and close solely through mechanical locking, leading to stiff operation and direct friction between metal parts, which can cause wear, loosening, or abnormal noise. For example, while some products use springs for assisted opening and closing, these springs are prone to fatigue and failure, and stepless angle adjustment is not possible, making it difficult to adapt to the personalized needs of users with different head circumferences. These problems make traditional eyeglass frames unable to meet the diverse requirements of modern usage scenarios in terms of comfort and fit. Utility Model Content
[0004] This invention improves the temple opening angle by using a structural design of an elastic hinge and an elastic force providing part, and generates an adaptive clamping force through the elastic contact of the elastic force providing part, thereby alleviating the problems mentioned in the background art.
[0005] The purpose of this utility model is achieved as follows: a pressure-relieving eyeglass frame includes a frame and temples disposed on both sides of the frame, and further includes:
[0006] An elastic hinge is disposed between the frame and each temple. The elastic hinge includes a fixed part fixedly connected to the frame, a rotating part hinged to the temple, and an elastic connecting part connecting the fixed part and the rotating part.
[0007] The elastic providing part includes a first elastic protrusion extending from the rotating part toward the fixing part, and a second elastic protrusion extending from the fixing part toward the rotating part;
[0008] The first elastic protrusion and the second elastic protrusion form an elastic contact fit during the unfolding of the temple.
[0009] The present invention is further configured such that the fixing part includes a connecting body and a fixing screw, and the connecting body is fixedly connected to the frame by the fixing screw.
[0010] The present invention is further provided that the temple is provided with a connecting body, the connecting body is provided with a receiving groove for embedding the rotating part, and is hinged to the rotating part by a hinge screw.
[0011] The present invention is further configured such that the first elastic protrusion and the second elastic protrusion are elastically contacted and engaged, so that the maximum unfolding angle of the temple is 120°.
[0012] The present invention is further configured such that the elastic providing part includes an insertion groove formed at the end of the second elastic protrusion, and when the temple is extended to the maximum angle, the first elastic protrusion is inserted into the insertion groove to lock the position.
[0013] The present invention is further configured such that the elastic connecting part is a C-shaped structure, and its two ends are integrally formed with the fixing part and the rotating part, respectively.
[0014] The present invention is further configured such that the elastic hinge is made entirely of β titanium alloy.
[0015] By adopting the above technical solution, the beneficial effects that this utility model can achieve are:
[0016] 1. Through the elastic contact and cooperation of the first elastic protrusion and the second elastic protrusion in the elastic hinge, the maximum opening angle of the temples can reach 120°, effectively solving the problem of head clamping caused by head swelling during exercise for users with larger head circumference, and significantly improving wearing comfort.
[0017] 2. Utilizing the elastic resistance generated by the elastic contact fit, the temples can automatically adjust the clamping force according to the wearer's head circumference, avoiding strong pressure on both sides of the head and solving the problem of discomfort from wearing for a long time.
[0018] 3. When the temples are extended to their maximum angle, the first elastic protrusion is inserted into the insertion groove at the end of the second elastic protrusion and locked in place. Combined with the buffering effect of the elastic contact, the opening and closing process is smooth and without jamming, and the lock is stable and does not loosen, thus improving the user experience.

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-3 :
[0024] Example 1:
[0025] This embodiment provides a stress-relieving eyeglass frame, including a frame 1 and temples 2 disposed on both sides of the frame 1, and further including:
[0026] The elastic hinge 3 is disposed between the frame 1 and each temple 2. The elastic hinge 3 includes a fixed part 30 fixedly connected to the frame 1, a rotating part 31 hinged to the temple 2, and an elastic connecting part 32 connecting the fixed part and the rotating part 31.
[0027] The elasticity providing part 4 includes a first elastic protrusion 40 extending from the rotating part 31 toward the fixing part 30, and a second elastic protrusion 41 extending from the fixing part 30 toward the rotating part 31;
[0028] The first elastic protrusion 40 and the second elastic protrusion 41 form an elastic contact engagement during the unfolding of the temple 2.
[0029] The elastic hinge 3 is used to connect the frame 1 and the temple 2, enabling the temple 2 to rotate and open and close elastically, and providing adaptive clamping force and cushioning function.
[0030] The fixing part 30 securely anchors the elastic hinge 3 to the frame 1, transferring stress to the frame 1 and preventing the hinge from loosening or falling off, thus ensuring structural stability. The fixing part 30 is typically a rectangular block structure and can be connected to the frame 1 by screws or clips.
[0031] The rotating part 31 serves as the pivot for the rotation of the temple 2, transmitting elastic force to the temple 2 to achieve smooth rotation and positioning within the temple's extended range. The rotating part 31 is typically an arc-shaped or rectangular plate structure, which can be rotatably connected to the temple 2 via screws or other means.
[0032] The elastic connection 32 stores and releases energy through elastic deformation, providing resistance to the opening and closing of the temple 2 and a restoring force. The elastic connection 32 can connect the fixed part 30 and the rotating part 31 by means of adhesive bonding or integral molding, forming an elastic cantilever structure.
[0033] The elastic force providing part 4 generates a variable damping force through elastic contact, thereby realizing the angle adjustment and positioning locking of the temple 2. The elastic force providing part 4 is located between the fixed part 30 and the rotating part 31 of the elastic hinge 3, forming an elastic contact interface.
[0034] The first elastic protrusion 40 and the second elastic protrusion 41 cooperate to generate elastic resistance, controlling the rotation damping of the temple 2. The contact ends of the first elastic protrusion 40 and the second elastic protrusion 41 are generally arc surfaces, and they contact each other at a 45° angle. The first elastic protrusion 40 extends from the side of the rotating part 31 toward the fixed part 30, and can be integrally formed and connected with the rotating part 31.
[0035] The second elastic protrusion 41 forms an elastic contact pair with the first elastic protrusion 40, providing a reaction force. The second elastic protrusion 41 is typically a rectangular block structure, extending from the side of the fixing part 30 toward the rotating part 31, and is distributed opposite to the first elastic protrusion 40. The second elastic protrusion 41 is integrally formed with the fixing part 30.
[0036] When the user unfolds or folds the temple 2, the rotating part 31 rotates around the hinge point, causing the first elastic protrusion 40 and the second elastic protrusion 41 to generate relative displacement. The elastic connecting part 32 undergoes elastic deformation simultaneously, storing or releasing elastic potential energy to assist the opening and closing of the temple 2.
[0037] Example 2:
[0038] This embodiment provides a pressure-relieving eyeglass frame, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0039] The fixing part 30 includes a connector 300 and a fixing screw 301, and the connector 300 is fixedly connected to the frame 1 by the fixing screw 301.
[0040] In this embodiment, the fixing part 30 is divided into a connecting body 300 and a fixing screw 301. The purpose is to achieve a stable connection between the elastic hinge 3 and the frame 1, while also taking into account ease of installation and structural maintainability. The connecting body 300, as an intermediate connecting part, disperses the stress generated when the temple 2 opens and closes through a tight fit with the frame 1, avoiding loosening or damage caused by single-point force. The fixing screw 301 further enhances the reliability of the connection, ensuring that it remains tight during long-term use. This combination design not only adapts to the installation requirements of different frame materials and structures, but also allows for quick replacement of the elastic hinge 3 by removing the screws, reducing maintenance costs and extending the overall service life of the eyeglass frame.
[0041] Example 3:
[0042] This embodiment provides a pressure-relieving eyeglass frame, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0043] The temple 2 is provided with a connecting body 5, which has a receiving groove 6 for embedding the rotating part 31 and is hinged to the rotating part 31 by a hinge screw 7.
[0044] In this embodiment, the connecting body 5 and the receiving groove 6 are disposed on the temple 2 and connected to the rotating part 31 by a hinge screw 7. The purpose is to achieve a flexible rotational connection between the temple 2 and the elastic hinge 3, while ensuring structural stability and ease of assembly. The cooperation between the connecting body 5 and the receiving groove 6 provides precise installation positioning for the rotating part 31, ensuring smooth and wobbly rotation when the temple 2 opens and closes. The hinge screw 7 reliably connects the rotating part 31 to the temple 2 through mechanical fastening, transmitting the opening and closing torque while preventing angular deviation caused by loosening. This structural design not only facilitates the disassembly and replacement of the temple 2 or the hinge, reducing maintenance difficulty, but also balances rotational flexibility and connection stability by optimizing the screw torque and the gap of the receiving groove 6, improving the reliability and comfort of the glasses for long-term use.
[0045] Example 4:
[0046] This embodiment provides a pressure-relieving eyeglass frame, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0047] The first elastic protrusion 40 and the second elastic protrusion 41 are elastically engaged to make the maximum unfolding angle of the temple 2 120°.
[0048] This embodiment utilizes the elastic contact between the first elastic protrusion 40 and the second elastic protrusion 41 to set the maximum unfolding angle of the temple 2 to 120°, aiming to overcome the bottleneck of limited angles in traditional eyeglass frames and improve wearing fit and comfort. Compared to the conventional eyeglass frames with an unfolding angle of ≤90°, the 120° design significantly reduces the pressure on the sides of the head from the temple 2, making it especially suitable for users with larger head circumferences or those experiencing slight head swelling during exercise. Simultaneously, the variable damping force generated by the elastic contact allows the temple 2 to achieve stepless positioning during unfolding, enabling users to freely adjust the angle according to their needs. Combined with the locking structure of the insertion slot 42, this ensures that the temple 2 remains stable and does not wobble at its maximum angle, thus balancing flexible adjustment and reliable fixation, comprehensively optimizing the wearing experience of the glasses.
[0049] Example 5:
[0050] This embodiment provides a pressure-relieving eyeglass frame, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0051] The elastic providing part 4 also includes an insertion groove 42 formed at the end of the second elastic protrusion 41. When the temple 2 is extended to the maximum angle, the first elastic protrusion 40 is inserted into the insertion groove 42 to lock the position.
[0052] In this embodiment, an insertion groove 42 is provided at the end of the second elastic protrusion 41, so that when the temple 2 is extended to its maximum angle, the first elastic protrusion 40 can be inserted therein to lock its position. The purpose is to provide a stable maximum angle limit for the temple 2, prevent excessive extension from causing structural damage, and enhance wearing stability. Compared with traditional eyeglass frames that do not have a clear angle locking or rely solely on friction positioning, this structure forms a rigid constraint through mechanical insertion, ensuring that the temple 2 remains fixed in its maximum extended state, avoiding angle displacement caused by external impact or long-term use. At the same time, in conjunction with the damping force generated by the elastic contact, it provides flexible adjustment functions and further ensures the reliability of the glasses in scenarios such as sports and daily use, improving product durability and user experience.
[0053] Example 6:
[0054] This embodiment provides a pressure-relieving eyeglass frame, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0055] The elastic connecting part 32 has a C-shaped structure, and its two ends are integrally formed with the fixed part 30 and the rotating part 31, respectively.
[0056] In this embodiment, the elastic connecting part 32 is designed as a C-shaped structure and integrally formed with the fixing part 30 and the rotating part 31. The purpose is to endow the eyeglass frame with efficient elastic cushioning and deformation capabilities through a unique structural form and manufacturing process, while improving the overall structural strength and stability. The C-shaped structure naturally has good elastic deformation characteristics, which can effectively absorb and release elastic potential energy during the opening and closing of the temple 2, assisting the temple 2 to rotate smoothly, while providing adaptive clamping force to fit different head circumferences; the integral forming process eliminates the connection gaps between components, avoids stress concentration, reduces the risk of loosening or breakage caused by frequent opening and closing, and ensures that the elastic hinge 3 maintains stable performance during long-term use, thereby significantly improving the durability and wearing comfort of the eyeglass frame.
[0057] Example 7:
[0058] This embodiment provides a pressure-relieving eyeglass frame, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0059] The elastic hinge 3 is made entirely of β-titanium alloy.
[0060] In this embodiment, the entire elastic hinge 3 is made of β-titanium alloy. The aim is to leverage the superior mechanical properties and material characteristics of β-titanium alloy to comprehensively improve the performance and quality of the eyeglass frame. β-titanium alloy possesses high strength, high elastic modulus, and excellent shape memory, enabling it to withstand the stress generated by the frequent opening and closing of the temples 2, significantly extending the product's lifespan. Simultaneously, its lightweight characteristics effectively reduce the overall weight of the glasses, decreasing the pressure felt when wearing them. Furthermore, the good biocompatibility and corrosion resistance of β-titanium alloy prevent skin allergies and adapt to different usage environments, thus balancing durability, comfort, and safety, optimizing the user's wearing experience.
[0061] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
