Abstract
Description
Technical Field
[0001] This invention belongs to the field of eyeglass structure technology, specifically relating to a damped suspension elastic eyeglass hinge and eyeglasses. Background Technology
[0002] As a common device for correcting vision, protecting the eyes, or for aesthetic purposes, eyeglasses' structural stability and fit directly affect the user experience. The core components of existing eyeglasses include the frame, temples, and the connecting structure between them. Among these, the hinge structure, due to its rotatable nature, has become the most mainstream connection method between the frame and temples. The rotation of the hinge allows the temples to be opened and closed, facilitating wearing and storage.
[0003] However, in actual use, existing eyeglasses based on hinge structures have significant fitting defects. Due to individual differences in head width among wearers, and the fact that the rotation angle of traditional hinge structures is usually within a fixed range, the opening angle of the temples cannot accurately match the head width of each wearer. When the temples open less than the wearer's head width, the temples exert a continuous clamping force on both sides of the wearer's head, which can easily cause discomfort such as head soreness and pressure pain with prolonged wear. When the temples open more than the wearer's head width, the glasses cannot fit stably, and are prone to slipping and wobbling during wear, affecting not only stability but also reducing ease of use due to frequent adjustments.
[0004] To address the aforementioned compatibility issues, an improvement scheme has been proposed in related technical fields: adding an elastic structure at the hinge position. The aim is to improve the adaptability range of the temple opening through the expansion, contraction, or deformation compensation of this elastic structure. However, practice has shown that glasses with this elastic structure still have significant shortcomings: the elastic effect of the hinge is mainly concentrated after the temple opens to 90° (approximately perpendicular to the frame). During the entire process of the temple rotating from the retracted to the extended state, and vice versa, the elastic structure provides almost no effective elastic resistance, resulting in insufficient resistance during temple rotation. This low resistance characteristic makes the temple prone to irregular swaying during rotation and difficult to achieve stable hovering at any non-90° opening angle. This not only increases the difficulty of adjusting the temple angle when wearing the glasses but also may cause sudden rotation due to accidental contact, affecting wearing safety and user experience. This defect is particularly pronounced in the field of smart glasses. Existing smart glasses integrate circuitry and batteries into the temples, resulting in generally heavier temples with greater swaying inertia, making the effects of this instability even more significant. Summary of the Invention
[0005] To address the problem of insufficient stability in the swinging and rotation of existing eyeglasses hinges, this invention provides a damped suspension elastic eyeglasses hinge and eyeglasses.
[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: On one hand, the present invention provides a damped, hovering elastic eyeglass hinge, comprising a first connecting portion, a second connecting portion, an elastic element, and a damping element. One end of the first connecting portion is provided with a first hinge portion, and one end of the second connecting portion is provided with a second hinge portion. The first hinge portion and the second hinge portion are hinged to form a hinge structure. The elastic element is a ring-like structure with an opening, and is coaxially arranged with the hinge structure. The elastic element has a first end and a second end that can move closer to or further away from each other at its opening position. The second end of the elastic element is connected to the second connecting portion, and the first end of the elastic element is a free end. The first end is provided with a protrusion extending axially along the elastic element. The damping element is located on the axial side of the elastic element, and the position of the damping element and the first connecting part is relatively fixed. When the temple of the glasses is unfolded from a folded state to approximately 90°, the protrusion abuts against the damping element to provide rotational damping. When the temple of the glasses is unfolded to approximately 90°, the first connecting part directly or indirectly abuts against the first end. When the temple of the glasses is further expanded from approximately 90°, the distance between the first end and the second end gradually decreases, and the elastic element undergoes elastic deformation to provide elasticity that limits the further expansion of the temple of the glasses.
[0007] Optionally, the damping element is provided with an arc-shaped slide, which includes a first free sliding section and a damping section connected in sequence. When the temple of the glasses unfolds from a folded state to approximately 90°, the protrusion slides in the damping section. The contact between the damping section and the protrusion creates a force that deforms the elastic element to provide rotational damping. When the temple of the glasses further expands outward from approximately 90°, the protrusion slides in the first free sliding section, and there is no force between the first free sliding section and the protrusion that causes the elastic element to deform.
[0008] Optionally, the damping section is a sawtooth structure, and the side of the protrusion contacts the sawtooth structure. When the temple of the glasses unfolds from the folded state to approximately 90°, the sawtooth structure cooperates with the protrusion to apply a radial force to the first end of the elastic member, so that the elastic member undergoes radial elastic deformation.
[0009] Optionally, the damping section is an arc-shaped groove formed on the damping member, the opening of the arc-shaped groove facing the elastic member, the arc-shaped groove including a first arc-shaped sidewall close to the rotation axis of the hinge structure and a second arc-shaped sidewall away from the rotation axis of the hinge structure; when the temple of the glasses unfolds from the folded state to approximately 90°, the first arc-shaped sidewall or the second arc-shaped sidewall of the arc-shaped groove presses against the protrusion to apply a radial force toward the elastic member to the first end of the elastic member, so that the elastic member undergoes radial elastic deformation.
[0010] Optionally, the damping section is an arc-shaped groove formed on the damping member, with the opening of the arc-shaped groove facing the elastic member. When the temple of the glasses unfolds from the folded state to approximately 90°, the bottom surface of the arc-shaped groove presses against the protrusion to apply a torsional force toward the axial direction of the elastic member to the first end of the elastic member, so that the elastic member undergoes axial torsional elastic deformation.
[0011] Optionally, the first free sliding segment is an arc-shaped through hole formed on the damping element.
[0012] Optionally, there are two elastic elements, which are spaced apart on the hinge structure and form a groove between them. Correspondingly, there are also two damping elements, which are respectively disposed on the outer side of the two elastic elements. The first end has protrusions on both sides. The arc-shaped slide also includes a second free sliding section, which is symmetrically disposed at both ends of the damping section with the first free sliding section.
[0013] Optionally, the damping element is a plastic part.
[0014] Optionally, the elastic element is selected from metal springs or non-metal springs, and the metal spring is selected from one of zirconium-based amorphous alloy springs, copper-based amorphous alloy springs, iron-based amorphous alloy springs, magnesium-based amorphous alloy springs, and titanium-based amorphous alloy springs.
[0015] In another aspect, the present invention provides an eyeglass, comprising an elastic hinge for eyeglasses as described above, an eyeglass frame, and an eyeglass temple, wherein a post is provided on the eyeglass frame, one of the first connecting portion and the second connecting portion is connected to the post, and the other of the first connecting portion and the second connecting portion is connected to the eyeglass temple.
[0016] According to the elastic eyeglass hinge provided by the present invention, the elastic element adopts an open, ring-like structure and surrounds the hinge structure, which not only ensures the uniformity of elastic deformation and the stability of restoring force, but also makes the structural layout compact, effectively reducing the overall volume of the elastic eyeglass hinge and achieving lightweighting. By setting a damping element that cooperates with the protrusion on the elastic element, stable rotational damping is provided during the critical adjustment process of unfolding the temple from the folded state to approximately 90°, effectively suppressing the irregular swinging of the temple, allowing the temple to be stably suspended at any angle within this rotation range, reducing the difficulty of adjusting the angle when wearing the glasses, avoiding accidental touches that could cause the temple to suddenly rotate, and improving wearing safety and ease of operation. Unlike traditional damping, the damping element is in direct contact with the elastic element, resulting in a longer service life, better stability, and a wider installation tolerance. Because the elastic element itself is elastic, by the elastic element abutting against the damping element, the elasticity of the elastic element can be used to prevent the spring from being fully extended. The pressure between the elastic element and the damping element is kept at a moderate level, avoiding the problems of excessive pressure leading to severe wear or insufficient pressure leading to insufficient damping. At the same time, after the damping element has undergone a certain degree of wear, it can still maintain a certain damping effect by relying on the adaptive deformation of the elastic element. Its damping retention effect after wear is better, and it also has a higher dimensional error tolerance during installation. When the temple of the glasses is opened to approximately 90° and then further expanded, the elastic deformation of the elastic element provides an elastic force to limit the outward expansion. It can be adaptively adjusted according to the width of the wearer's head, avoiding the clamping feeling caused by opening too small and the slipping feeling caused by opening too large, thus making up for the poor adaptability of traditional fixed-angle hinges.

[0019] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0020] See Figure 1 and Figure 2 As shown, the present invention provides a damped suspension elastic eyeglass hinge, including a first connecting part 1, a second connecting part 2, an elastic element 3, and a damping element 4. One end of the first connecting part 1 is provided with a first hinge portion 11, and one end of the second connecting part 2 is provided with a second hinge portion 21. The first hinge portion 11 and the second hinge portion 21 are hinged to form a hinge structure. The elastic element 3 is a ring-like structure with an opening. The elastic element 3 is coaxially arranged with the hinge structure. The elastic element 3 has a first end 31 and a second end 32 at its opening position that can move closer to or further away from each other. The second end 32 of the elastic element 3 is connected to the second connecting part 2, and the first end 31 of the elastic element 3 is... At the free end, the first end 31 is provided with a protrusion 311 that protrudes axially along the elastic member 3. The damping member 4 is located on the axial side of the elastic member 3, and the position of the damping member 4 is relatively fixed with that of the first connecting part 1. When the temple of the glasses is unfolded from a folded state to approximately 90°, the protrusion 311 abuts against the damping member 4 to provide rotational damping. When the temple of the glasses is unfolded to approximately 90°, the first connecting part 1 directly or indirectly abuts against the first end 31. When the temple of the glasses is further expanded from approximately 90°, the distance between the first end 31 and the second end 32 gradually decreases, and the elastic member 3 undergoes elastic deformation to provide elasticity that limits the further expansion of the temple of the glasses.
[0021] In the aforementioned elastic eyeglass hinge, the elastic element 3 adopts an open, ring-like structure and surrounds the hinge structure. This ensures both the uniformity of elastic deformation and the stability of the restoring force, while also making the structural layout compact and effectively reducing the overall volume of the elastic eyeglass hinge, thus achieving lightweight design. By setting a damping element 4 to cooperate with the protrusion 311 on the elastic element 3, stable rotational damping is provided during the critical adjustment process of unfolding the temples from a folded state to approximately 90°. This effectively suppresses irregular swaying of the temples, allowing them to remain stably suspended at any angle within this rotation range. This reduces the difficulty of adjusting the angle during wear, prevents accidental contact that could cause sudden rotation of the temples, and improves wearing safety and ease of operation. Unlike traditional damping, the damping element 4 directly contacts the elastic element 3, resulting in a longer service life, better stability, and a wider tolerance for installation errors. Because the elastic element 3 itself is elastic, by abutting the damping element 4, the elasticity of the elastic element 3 allows for... The pressure between the elastic element 3 and the damping element 4 is in a moderate state, avoiding the problem of excessive pressure leading to severe wear or excessive pressure leading to insufficient damping. At the same time, after the damping element 4 has undergone a certain degree of wear, it can still maintain a certain damping effect by relying on the adaptive deformation of the elastic element 3. Its damping retention effect after wear is better, and it also has a higher dimensional error tolerance during installation. When the temple of the glasses is opened to approximately 90° and then further expanded, the elastic deformation of the elastic element 3 provides an elastic force to limit the outward expansion. It can be adaptively adjusted according to the width of the wearer's head, avoiding the clamping feeling caused by opening too small and the slipping feeling caused by opening too large, thus making up for the poor adaptability of traditional fixed-angle hinges.
[0022] In the addition of damping to the elastic eyeglass hinge, although the problem of irregular swinging of the temples is overcome, in some implementation scenarios, the added damping will have an adverse effect on the adaptive elasticity of the elastic eyeglass hinge. Specifically, when the temples are extended to approximately 90° and then further expanded outward, the presence of damping will inhibit the elasticity of the elastic element 3, and may even cause the elastic element 3 to lose its elastic adaptation function.
[0023] In response to the above-mentioned new problems, the inventors made further improvements to the shape of the damping element 4.
[0024] Specifically, in some embodiments, the damping member 4 is provided with an arc-shaped slide 41, which includes a first free sliding section 411 and a damping section 413 connected in sequence. When the temple of the glasses unfolds from a folded state to approximately 90°, the protrusion 311 slides in the damping section 413. The contact between the damping section 413 and the protrusion 311 creates a force that deforms the elastic member 3 to provide rotational damping. When the temple of the glasses expands further from approximately 90°, the protrusion 311 slides in the first free sliding section 411, and there is no force between the first free sliding section 411 and the protrusion 311 that causes the elastic member 3 to deform.
[0025] By dividing the arc-shaped slide 41 into a first free sliding section 411 and a damping section 413, stable damping is obtained in the adjustment stage when the temple of the glasses is extended to approximately 90° (damping section 413), ensuring the stability of hovering and rotation; while in the adaptation stage after the temple of the glasses is extended to 90° and further expanded outward (first free sliding section 411), the damping component 4 no longer exerts deformation force on the elastic component 3, ensuring that the elastic component 3 can smoothly undergo elastic deformation to achieve adaptation adjustment, avoiding the interference of damping force on the adaptation effect, and improving the smoothness of the user experience.
[0026] In some embodiments, the elastic element 3 is not a flat, ring-shaped structure, but a cylindrical structure with a sidewall opening having a certain axial thickness. The axial thickness of the elastic element 3 is 0.5~5mm, more preferably 1~4mm.
[0027] Based on the above-mentioned arc-shaped slide 41, the present invention provides three implementation structures, as shown in the following first embodiment, second embodiment and third embodiment, to achieve different effects.
[0028] like Figure 3 As shown, in the first embodiment, the damping section 413 is a sawtooth structure, and the side of the protrusion 311 contacts the sawtooth structure. When the temple of the glasses unfolds from the folded state to approximately 90°, the sawtooth structure cooperates with the protrusion 311 to apply a radial force to the first end 31 of the elastic member 3, so that the elastic member 3 undergoes radial elastic deformation.
[0029] The damping section 413 adopts a sawtooth structure. Through the meshing contact between the sawtooth and the side of the protrusion 311, the magnitude and direction of the radial force applied to the first end 31 of the elastic element 3 can be precisely controlled, so that the elastic element 3 produces a stable radial elastic deformation, thereby forming uniform and adjustable rotational damping. This ensures that the temple of the glasses can be stably suspended at multiple trough positions within the sawtooth structure. This sawtooth structure can provide a more stable suspension effect.
[0030] like Figure 4As shown, in the second embodiment, the damping section 413 is an arc-shaped groove formed on the damping member 4, the opening of the arc-shaped groove facing the elastic member 3, the arc-shaped groove including a first arc-shaped sidewall 4131 near the rotation axis of the hinge structure and a second arc-shaped sidewall 4132 away from the rotation axis of the hinge structure; when the temple of the glasses unfolds from the folded state to approximately 90°, the first arc-shaped sidewall 4131 or the second arc-shaped sidewall 4132 of the arc-shaped groove presses against the protrusion 311 to apply a radial force to the first end 31 of the elastic member 3, so that the elastic member 3 undergoes radial elastic deformation.
[0031] Specifically, the arc-shaped groove and the elastic element 3 are concentric. The compression of the first arc-shaped sidewall 4131 or the second arc-shaped sidewall 4132 against the protrusion 311 can be achieved by adjusting the radius of the damping section 413, such as... Figure 5 As shown, when the radius of the damping section 413 is smaller than the radius of the elastic member 3, the second arc-shaped sidewall 4132 presses against the protrusion 311; as Figure 6 As shown, when the radius of the damping section 413 is greater than the radius of the elastic member 3, the first arc-shaped sidewall 4131 presses against the protrusion 311.
[0032] Radial force is generated by pressing the protrusion 311 through the first arc-shaped sidewall 4131 or the second arc-shaped sidewall 4132 of the arc groove. The arc-shaped sidewall and the protrusion 311 are in surface contact, which makes the force transmission more uniform and the damping force uniform and gentle. It avoids the damping abrupt change caused by local stress concentration, so that the temple of the glasses can rotate smoothly and steadily, reducing the operating force during adjustment. It is suitable for the structure of conventional glasses with lighter temples and improves the wearer's comfort.
[0033] like Figure 7 As shown, in the third embodiment, the damping section 413 is an arc-shaped groove formed on the damping member 4. The opening of the arc-shaped groove faces the elastic member 3. When the temple of the glasses unfolds from the folded state to approximately 90°, the bottom surface of the arc-shaped groove presses against the protrusion 311 to apply a torsional force toward the axial direction of the elastic member 3 to the first end 31 of the elastic member 3, so that the elastic member 3 undergoes axial torsional elastic deformation.
[0034] like Figure 8 The diagram shown is a schematic representation of the cooperation between the protrusion 311 and the damping section 413 in the third embodiment.
[0035] The difference between the third embodiment and the second embodiment is that in the third embodiment, the elastic element 3 undergoes axial torsional elastic deformation by pressing the bottom surface of the arc groove. Since the elastic element 3 has a certain axial thickness, the elastic force generated by its axial torsional elastic deformation is much greater than the elastic force generated by its radial elastic deformation in the second embodiment. This ensures that the elastic element 3 generates a large elastic force under a small deformation, thereby forming a large damping force. The damping element 4 structure of the third embodiment is suitable for eyeglasses with heavy temples, such as smart glasses, and can ensure the stability of the eyeglass temples during folding and unfolding.
[0036] In some embodiments, the first free sliding segment 411 is an arc-shaped through hole or clearance groove formed on the damping member 4.
[0037] The first free sliding section 411 adopts an arc-shaped through-hole structure. When the protrusion 311 slides in the first free sliding section 411, the contact area with the inner wall of the through-hole is small, which can minimize the sliding resistance and ensure that when the temple of the glasses expands outward after 90°, the damping generated by the damping member 4 will not affect the outward expansion elasticity of the elastic member 3.
[0038] In some embodiments, the damping element 4 is a circular or annular sheet, and both the damping element 4 and the elastic element 3 are coaxially arranged with the rotation axis of the hinge structure as the axial direction. A limiting portion 42 is provided at the edge of the damping element 4, which abuts against the first connecting portion 1 to prevent the relative position of the damping element 4 and the first connecting portion 1 from being fixed. During the rotation of the elastic element 3 driven by the second connecting portion 2, the damping element 4 and the elastic element 3 undergo relative movement.
[0039] In some embodiments, the number of elastic elements 3 is two, and the two elastic elements 3 are spaced apart on the hinge structure. A groove 12 is formed between the two elastic elements 3. Correspondingly, the number of damping elements 4 is also two, and the two damping elements 4 are respectively disposed on the outer side of the two elastic elements 3. The protrusions 311 are provided on both sides of the first end 31. The arc-shaped slide 41 also includes a second free sliding section 412. The second free sliding section 412 and the first free sliding section 411 are symmetrically disposed at both ends of the damping section 413.
[0040] Two spaced elastic elements 3 and corresponding damping elements 4 are used to ensure that both sides of the temples are subjected to uniform damping force and elastic force during rotation. At the same time, a groove 12 is formed between the two elastic elements 3, which is suitable for smart glasses with a wide temple.
[0041] The first end 31 has protrusions 311 on both sides, and the second free sliding section 412 is designed to prevent mistakes. Since the damping element 4 is only located on the outside of the elastic element 3, the installation of the elastic element 3 and the damping element 4 needs to take into account the installation direction. If the protrusion 311 is only provided on one side of the first end 31, the protrusion 311 will abut against the side of the damping element 4 that does not have the arc-shaped sliding track 41 due to the incorrect installation position of the elastic element 3, affecting its damping effect. If only the first free sliding section 411 is provided and the second free sliding section 412 is not provided, the first free sliding section 411 will not correspond to the travel of the protrusion 311 as it expands outward from approximately 90° on the temple of the glasses due to the incorrect installation direction of the damping element 4. The additional design of providing the protrusions 311 on both sides of the first end 31 and the second free sliding section 412 can effectively avoid the above problems. It can eliminate the need to distinguish the installation position of the elastic element 3 and the installation direction of the damping element 4, effectively reducing the assembly difficulty.
[0042] Furthermore, the second free sliding segment 412 is positioned at the location of the protrusion 311 when the temple is in a folded state. By setting the second free sliding segment 412 at this location, it can be ensured that the temple tends to fold to a preset position during the folding process, thus preventing the temple from not folding properly and ensuring the stability of the temple when it is in a folded state.
[0043] In some embodiments, the second free sliding segment 412 is an arc-shaped through hole or clearance groove formed on the damping member 4.
[0044] In some embodiments, the protrusion 311 is a hemispherical structure.
[0045] In some embodiments, the damping element 4 is a plastic part.
[0046] Compared to other materials, using plastic parts as damping components 4 provides stable damping. Specifically, plastics with wear-resistant properties can be selected, such as polyoxymethylene, nylon, polycarbonate, polyurethane, polytetrafluoroethylene, polyamide, polysulfone, polyetheretherketone, polybutylene terephthalate, polyphenylene sulfide, etc. Fillers or fibers can also be added to the plastic parts to provide reinforcement.
[0047] In some embodiments, the second end 32 of the elastic member 3 is provided with an insertion block 321, the second connecting portion 2 is provided with an insertion groove 22, the insertion block 321 is inserted into the insertion groove 22, and the first end 31 of the elastic member 3 is provided with a limiting block 312. When the temple of the glasses is extended to approximately 90°, the limiting block 312 abuts against the first connecting portion 1 to provide elasticity that limits further outward expansion of the temple of the glasses.
[0048] In some embodiments, the elastic element 3 is selected from metal springs or non-metal springs, and the metal springs are selected from one of zirconium-based amorphous alloy springs, copper-based amorphous alloy springs, iron-based amorphous alloy springs, magnesium-based amorphous alloy springs, and titanium-based amorphous alloy springs.
[0049] In a preferred embodiment, the elastic element 3 is selected from zirconium-based amorphous alloys.
[0050] Zirconium-based amorphous alloys boast high strength, with a tensile strength of 800-1500 MPa, 2.5 times that of 316 stainless steel and 1.5 times that of titanium alloys. This allows for thinner and lighter hinge designs, reducing component weight and improving wearer comfort. The high strength also ensures the glasses won't deform during long-term use, enhancing their overall quality. Furthermore, the Vickers hardness of zirconium-based amorphous alloys is 440-540 Hv, far exceeding that of stainless steel and titanium alloys, resulting in less wear during use. It also doesn't deform or lose elasticity over extended periods. The elastic deformation rate of zirconium-based amorphous alloys is 0.6-1.5%, six times higher than 316 stainless steel, offering better elasticity and improved wearing comfort.
[0051] Another embodiment of the present invention provides an eyeglass, including an elastic hinge for eyeglasses, an eyeglass frame and an eyeglass temple as described above, wherein a post is provided on the eyeglass frame, one of the first connecting part 1 and the second connecting part 2 is connected to the post, and the other of the first connecting part 1 and the second connecting part 2 is connected to the eyeglass temple.
[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
