Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to an elastic hinge for glasses and glasses. Background Art

[0002] The glasses hinge is used to connect the temple and the spectacle frame; usually, the temples in the glasses frames used by people are strip-shaped, and the temples and the spectacle frame are connected through a hinge structure. When the glasses are in use, the temples are fully opened, placed on the ears, and clamped on both sides of the face to fix the spectacle ring; the opening amplitude of the temples usually cannot just adapt to the head width of the wearer. If the opening amplitude of the temples is too small, it will clamp the head and cause discomfort when wearing; if the opening amplitude of the temples is too large, it will cause insufficient stability in wearing the glasses and the problem that the spectacle frame is prone to deviation.

[0003] There is a type of existing elastic hinge for glasses, which is provided with an elastic structure to make the temple and the spectacle frame have a certain elasticity, so as to improve the adaptability and wearing comfort. However, the elasticity of this kind of elastic hinge for glasses is mainly reflected after the opening angle of the temple is 90°. During the process of the temple unfolding and retracting, the resistance of the temple is small, and there are problems of insufficient swing and hovering stability of the temple.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] See Figure 1 and Figure 2As shown in the figure, the first embodiment of the present utility model provides an elastic hinge for glasses, which includes a first connecting portion 1, a second connecting portion 2, an elastic member 4 and a damping member 3. One end of the first connecting portion 1 is provided with a first hinge portion 11, and one end of the second connecting portion 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 member 4 is an annular-like structure with an opening. The elastic member 4 is disposed around the first hinge portion 11. The elastic member 4 has a first end portion 41 and a second end portion 42 that can approach or move away from each other at the opening position. The damping member 3 abuts against the elastic member 4 or the second hinge portion 21 to provide damping when the temple is unfolded or retracted. When the temple is unfolded to approximately 90°, the first connecting portion 1 directly or indirectly abuts against the first end portion 41, and the second connecting portion 2 directly or indirectly abuts against the second end portion 42. When the temple is further expanded from approximately 90°, the distance between the first end portion 41 and the second end portion 42 gradually decreases, and the elastic member 4 undergoes elastic deformation to provide elasticity for restricting further expansion of the temple.

[0025] Compared with other existing elastic hinge structures, the elastic hinge for glasses adopts the design of surrounding the first hinge portion 11 with the elastic member 4. The internal space of the elastic member 4 is filled by the first hinge portion 11, realizing the full utilization of space, reducing the volume of the elastic hinge for glasses, and avoiding problems of aesthetics or wearing comfort caused by the too large volume of the elastic hinge for glasses. At the same time, in order to ensure the stability of the temple during the unfolding and retracting processes, a damping member 3 is provided. The damping member 3 abuts against the elastic member 4 or the second hinge portion 21. Thus, during the relative rotation of the first connecting portion 1 and the second connecting portion 2, a damping is formed through the frictional force generated by the damping member 3 to realize the hovering of the temple at any point during the unfolding and retracting processes and maintain the stability of the temple at the hovering position. Especially when the temple is in the unfolded and retracted states, even if the spectacle frame is taken alone at this time, it will not cause the temple to shake.

[0026] In this embodiment, the damping member 3 is a plastic part.

[0027] Compared with other materials, by using a plastic part as the damping member 3, it has the characteristic of stable damping. Specifically, plastics with wear-resistant characteristics can be selected, such as polyoxymethylene, nylon, polycarbonate, polyurethane, polytetrafluoroethylene, polyamide, polysulfone, polyether ether ketone, polybutylene terephthalate, polyphenylene sulfide, etc. Fillers or fibers can also be added to the plastic part to play a reinforcing role.

[0028] Such as Figure 3 and Figure 4 As shown in the figure, in the second embodiment of the present utility model, the damping member 3 abuts against the second hinge portion 21.

[0029] During the process of the temple arms unfolding and retracting, the damping member 3 and the second hinge portion 21 slide relative to each other, and a damping effect is generated through the frictional force between the damping member 3 and the second hinge portion 21, ensuring the stability of the temple arms.

[0030] As Figure 1 and Figure 2 shown, in the first embodiment of the present invention, the damping member 3 abuts against the elastic member 4.

[0031] During the process of the temple arms unfolding and retracting, the damping member 3 and the elastic member 4 slide relative to each other, and a damping effect is generated through the frictional force between the damping member 3 and the elastic member 4, ensuring the stability of the temple arms.

[0032] Compared with the structure of the second embodiment, the method of realizing damping by abutting the damping member 3 against the elastic member 4 in the first embodiment has a longer service life, better stability and a wider allowable installation error, because the elastic member 4 itself has elasticity. By abutting the elastic member 4 against the damping member 3, the pressure between the elastic member 4 and the damping member 3 can be kept in a relatively moderate state by relying on the elasticity of the elastic member 4, avoiding the problems of serious wear caused by too high pressure or too small damping caused by too low pressure. At the same time, after the damping member 3 has a certain amount of wear, it can also rely on the adaptive deformation of the elastic member 4 to maintain a certain damping effect. Compared with the structure of the second embodiment, its damping retention effect after wear is better, and it also has a higher dimensional tolerance rate during installation.

[0033] In some embodiments, the number of the first hinge portions 11 is one, the number of the second hinge portions 21 is two, the elastic member 4 is disposed around the outer periphery of the first hinge portion 11, and the two second hinge portions 21 are disposed on both sides of the first hinge portion 11. A hinge screw is passed through the first hinge portion 11 and the two second hinge portions 21 to form a hinge structure.

[0034] The first hinge portion 11 and the second hinge portion 21 are of a similar circular ring structure, and the first hinge portion 11 and the second hinge portion 21 are coaxially arranged. The hinge screw is fixed on the two second hinge portions 21, and the first hinge portion 11 rotates relative to the hinge screw.

[0035] The inner diameter of the elastic member 4 is larger than the outer diameter of the first hinge portion 11, so that there is a deformation space between the elastic member 4 and the first hinge portion 11, which is beneficial to ensuring the elastic effect of the elastic member 4.

[0036] The opening width of the elastic member 4 is smaller than the outer diameter of the first hinge portion 11, preventing the elastic member 4 from falling off the first hinge portion 11.

[0037] The outer diameter of the second hinge portion 21 is larger than that of the first hinge portion 11, such that the elastic member 4 is at least partially located in the overlapping area of the projections of the two second hinge portions 21. The two second hinge portions 21 play a certain protective role for the elastic member 4, preventing external debris from entering the gap between the elastic member 4 and the first hinge portion 11.

[0038] In some embodiments, the damping member 3 includes a damping portion 31, a first gasket 32 and a second gasket 33. The first gasket 32 and the second gasket 33 are connected to the damping portion 31 in parallel at intervals. The damping portion 31 abuts against the elastic member 4 or the second hinge portion 21. The first gasket 32 and the second gasket 33 are respectively located on both sides of the first hinge portion 11, and the first gasket 32 and the second gasket 33 are located between the first hinge portion 11 and the second hinge portion 21.

[0039] Both the first hinge portion 11 and the second hinge portion 21 are metal parts. If the first hinge portion 11 and the second hinge portion 21 are in direct rigid contact, wear is likely to occur during long-term rotation, resulting in a decrease in the frictional force between the first connecting portion 1 and the second connecting portion 2, and there is a problem of unstable structure. The first gasket 32 and the second gasket 33 provided have a certain damping effect like the damping portion 31. More importantly, the first gasket 32 and the second gasket 33 have the function of preventing wear between the first connecting portion 1 and the second connecting portion 2. Since the first gasket 32 and the second gasket 33 are plastic parts, their surfaces in contact with the metal have a deformation adaptation effect, which can reduce surface wear during long-term use. At the same time, even after wear occurs, replacing only the damping member 3 has better cost advantages because the first connecting portion 1 and the second connecting portion 2 are usually integrally formed with the spectacle frame and the spectacle leg respectively, resulting in relatively high replacement costs.

[0040] As Figure 3 and Figure 4 shown, in the second embodiment, one side of the damping portion 31 abuts against the first connecting portion 1, and the other side of the damping portion 31 abuts against the second hinge portion 21.

[0041] During the rotation of the spectacle leg, the position of the damping portion 31 is relatively stationary with respect to the first connecting portion 1, and the second hinge portion 21 and the damping portion 31 slide relative to each other.

[0042] In the second embodiment, the first connecting portion 1 is provided with a first card slot 12, the first end portion 41 of the elastic member 4 is embedded in the first card slot 12, and the first card slot 12 fixes the first end of the elastic member 4. The second end of the elastic member 4 is a free end. The inner wall of the second hinge portion 21 is provided with a second card slot 23. The second end portion 42 of the elastic member 4 is provided with two locking blocks 421. When the temple is unfolded to approximately 90°, the two locking blocks 421 are respectively embedded and abutted against the two second card slots 23. During the process of the temple being unfolded to approximately 90°, the first connecting portion 1 drives the damping portion 31 to rotate relative to the second connecting portion 2, and the damping portion 31 slides around the outer wall of the second hinge portion 21 and provides damping. When the temple is further expanded outward from approximately 90°, the second hinge portion 21 drives the second end portion 42 of the elastic member 4, and the first connecting portion 1 drives the first end portion 41 of the elastic member 4, so that the first end portion 41 and the second end portion 42 of the elastic member 4 approach each other relatively, which serves to provide the outward expansion elasticity of the temple.

[0043] As Figure 1 and Figure 2 shown, in the first embodiment, the damping portion 31 is embedded in the second connecting portion 2, and the damping portion 31 abuts against the outer wall of the elastic member 4.

[0044] In the first embodiment, the first connecting portion 1 is provided with a first card slot 12, the first end portion 41 of the elastic member 4 is embedded in the first card slot 12, and the first card slot 12 fixes the first end of the elastic member 4. The second end of the elastic member 4 is a free end. The second connecting portion 2 is provided with a third card slot 22 at the position between the two second hinge portions 21. The damping portion 31 is embedded and fixed in the third card slot 22, so that the positions of the damping member 3 and the second connecting portion 2 are relatively fixed, and the outer wall of the elastic member 4 abuts against the side wall of the damping portion 31. The second end portion 42 of the elastic member 4 is provided with two locking blocks 421. When the temple is unfolded to approximately 90°, the two locking blocks 421 abut against the damping portion 31. During the process of the temple being unfolded to approximately 90°, the second connecting portion 2 drives the damping portion 31 to rotate relative to the first connecting portion 1. At this time, since one end of the elastic member 4 is fixed relative to the first connecting portion 1, the damping portion 31 slides around the outer wall of the elastic member 4 and provides damping. When the temple is further expanded outward from approximately 90°, the damping portion 31 drives the second end portion 42 of the elastic member 4, and the first connecting portion 1 drives the first end portion 41 of the elastic member 4, so that the first end portion 41 and the second end portion 42 of the elastic member 4 approach each other relatively, which serves to provide the outward expansion elasticity of the temple.

[0045] In some embodiments, the elastic member 4 is selected from a metal shrapnel or a non-metal shrapnel, and the metal shrapnel is selected from a zirconium-based amorphous alloy shrapnel, a copper-based amorphous alloy shrapnel, an iron-based amorphous alloy shrapnel, a magnesium-based amorphous alloy shrapnel, or a titanium-based amorphous alloy shrapnel.

[0046] In a preferred embodiment, the elastic member 4 is selected from a zirconium-based amorphous alloy.

[0047] The zirconium-based amorphous alloy has high material strength, with a tensile strength of 800 - 1500 MPa, which is 2.5 times that of 316 stainless steel and 1.5 times that of titanium alloy. The hinge structure can be designed to be thinner and lighter, reducing the weight of the accessories and improving the comfort of the wearer. At the same time, the high strength of the material ensures that the glasses do not deform during long-term use, improving the quality of the glasses. Moreover, the Vickers hardness of the zirconium-based amorphous alloy is 440 - 540 Hv, far exceeding that of stainless steel and titanium alloy, with little wear during use. It also does not deform or have a reduced elasticity during long-term use. The elastic deformation rate of the zirconium-based amorphous alloy material is 0.6 - 1.5%, which is 6 times higher than that of 316 stainless steel, with better elasticity and better wearing comfort.

[0048] Another embodiment of the present invention provides a pair of glasses, including the elastic hinge for glasses, the spectacle frame, and the temple as described above. A stud is provided on the spectacle frame, and one of the first connecting portion 1 and the second connecting portion 2 is connected to the stud, and the other of the first connecting portion 1 and the second connecting portion 2 is connected to the temple.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
