Description

Technical Field

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

[0002] The hinge of glasses is used to connect the temples of glasses and the frames of glasses. The temples of glasses frames that people usually use are strip-shaped. The temples of glasses and the frames of glasses are connected by a hinge structure. When the glasses are used, the temples of glasses are fully opened, placed on the ears, and clamped on both sides of the face to fix the rims of the glasses. The opening range of the temples of glasses usually cannot just adapt to the width of the wearer's head. If the opening range of the temples of glasses is too small, it will clamp the head and cause discomfort when wearing. If the opening range of the temples of glasses is too large, it will cause the glasses to be worn with insufficient stability and the frames of glasses will be easily offset.

[0003] There is a type of elastic hinge for glasses that provides a certain degree of elasticity between the glasses legs and the glasses frame by setting an elastic structure, thereby improving adaptability and wearing comfort. However, the elasticity of this type of elastic hinge for glasses is mainly reflected in the elastic force formed when the glasses legs are unfolded at an angle of 90°. During the process of unfolding and retracting the glasses legs, the resistance of the glasses legs is small, resulting in insufficient stability in swinging and hovering of the glasses legs.

[0004] In particular, with the development of intelligent wearable devices, when this type of glasses hinge is applied to smart glasses, since the glasses legs are usually equipped with electronic devices such as speakers or other sensors, the weight of the glasses legs is usually large, and the lack of swing and hovering stability of the glasses hinge is more obvious. When not in use, it is easy to shake and produce a large swing amplitude.

[0005] On the other hand, in smart glasses, electrical connecting lines are inevitably set between the temples and the frames for signal transmission or power supply. When setting the elastic structure of existing glasses elastic hinges, the elastic structure and the electrical connecting lines are set in the same cavity. During the long-term unfolding and folding process of the temples, the deformation movement of the elastic structure will interfere with the electrical connecting lines, thereby causing wear of the electrical connecting lines and affecting the stability of their electrical connection.

[0019] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] See also Figures 1 to 6As shown, an embodiment of the present invention provides an elastic wire-passing hinge for glasses, including a first connecting part 1, a second connecting part 2 and an elastic member 5, wherein a first wire-passing cavity 15 is arranged inside the first connecting part 1, and a second wire-passing cavity 223, an elastic mounting cavity 213 and a transfer cavity 224 are arranged inside the second connecting part 2, the first connecting part 1 is provided with a hinge plate 11, the second connecting part 2 is rotatably connected to the hinge plate 11, and the elastic mounting cavity 213 and the transfer cavity 224 are separated from each other by the hinge plate 11, the first wire-passing cavity 15 and the second wire-passing cavity 223 are interconnected via the transfer cavity 224 to form a wire-passing channel for the electrical connection line to pass through, the elastic member 5 is located in the elastic mounting cavity 213, and when the glasses leg is unfolded to approximately 90°, the elastic member 5 respectively abuts against the hinge plate 11 and the second connecting part 2; when the glasses leg is further expanded outward from approximately 90°, the elastic member 5 undergoes elastic deformation to provide elasticity to limit the further expansion of the glasses leg.

[0021] Compared with other existing elastic hinge wire-passing structures, the elastic wire-passing hinge for glasses provided by the present invention is provided with a first connecting part 1 and a second connecting part 2 that can rotate with each other, and an elastic mounting cavity 213 and a transfer cavity 224 are provided in the second connecting part 2. When the first connecting part 1 and the second connecting part 2 are rotationally connected, the elastic mounting cavity 213 and the transfer cavity 224 are separated from each other by the hinge plate 11, wherein the elastic mounting cavity 213 is used for the installation and accommodation of the elastic member 5, and the transfer cavity 224 is used to form a wire-passing channel together with the first wire-passing cavity 15 and the second wire-passing cavity 223, thereby effectively separating the elastic member 5 and the wire-passing channel from each other, thereby ensuring that during the unfolding and folding process of the glasses legs, the deformation of the elastic member 5 and the electrical connection wires in the wire-passing channel do not interfere with each other, thereby ensuring the electrical connection stability and elastic function.

[0022] In one embodiment, the second connecting portion 2 includes a first component 21 and a second component 22, the first component 21 includes a first connecting structure 211 and a first fastener 212 connected to each other, the second component 22 includes a second connecting structure 221 and a second fastener 222 connected to each other, the first connecting structure 211 connects the second connecting structure 221, the first fastener 212 and the second fastener 222 are respectively sleeved on both sides of the hinge plate 11, the elastic mounting cavity 213 is located in the first fastener 212 and is closed by the hinge plate 11, and the transfer cavity 224 is located in the second fastener 222 and is closed by the hinge plate 11.

[0023] The second connecting portion 2 is configured as a first component 21 and a second component 22 that are independent of each other. The first connecting structure 211 and the second connecting structure 221 can be connected to each other by screws or other means for fixed installation. At the same time, the elastic mounting cavity 213 is located in the first fastener 212 and is closed by the hinge plate 11, and the transfer cavity 224 is located in the second fastener 222 and is closed by the hinge plate 11, which is conducive to separating the mounting structures of the elastic mounting cavity 213 and the transfer cavity 224 from each other. When the elastic over-the-line hinge for the glasses is repaired, the first component 21 or the second component 22 can be separated separately to expose the elastic mounting cavity 213 and the transfer cavity 224, and then the components inside the elastic mounting cavity 213 and the transfer cavity 224 can be repaired separately, thereby avoiding the influence of the repair operation on other non-repair functional components and the disassembly operation, which is conducive to reducing the difficulty of repair.

[0024] like Figure 4 As shown, in one embodiment, the second wire passage cavity 223 is located in the second connection structure 221, and the second connection structure 221 opens a first channel 225 connecting the transfer cavity 224 and the first wire passage cavity 15, as shown in FIG. Figure 5 As shown, a second channel 14 is opened in the hinge plate 11 to connect the transfer cavity 224 and the first wire passing cavity 15 .

[0025] By arranging the second channel 14 on the hinge plate 11, specifically, the hinge plate 11 is a quasi-circular structure, and the second channel 14 is led out from the center position of the hinge plate 11, it is helpful to reduce the interference problem between the electrical connection line and the second connection structure 221 during the rotation of the elastic wire hinge for glasses.

[0026] In one embodiment, the elastic over-the-line hinge for glasses also includes a damping member 3, the elastic member 5 is a ring-like structure with an opening, the elastic member 5 is arranged around the second connecting part 2 and the rotation axis of the hinge plate 11, and the elastic member 5 has a first end 51 and a second end 52 that can approach or move away from each other at the opening position; the damping member 3 abuts against the elastic member 5 to provide damping when the temples are unfolded or retracted; when the temples are unfolded to approximately 90°, the hinge plate 11 directly or indirectly abuts against the first end 51, and the first buckle 212 directly or indirectly abuts against the second end 52; when the temples are further expanded outward from approximately 90°, the distance between the first end 51 and the second end 52 gradually decreases, and the elastic member 5 undergoes elastic deformation to provide elasticity to limit the further expansion of the temples.

[0027] Compared with other existing elastic hinge structures, the elastic hinge for glasses adopts an elastic member 5 with an open ring-like structure, which can achieve a longer elastic stroke in a smaller space, reduce the volume of the elastic over-the-line hinge for glasses, and avoid the problem of aesthetics or wearing comfort caused by the excessive volume of the elastic over-the-line hinge for glasses.

[0028] In order to ensure the stability of the temples during the unfolding and retracting process, a damping member 3 is provided, and the damping member 3 abuts against the elastic member 5, so that during the relative rotation of the first connecting part 1 and the second connecting part 2, damping is formed by the friction force generated by the damping member 3, so as to achieve the hovering of the temples at any point during the unfolding and retracting process and maintain the stability of the temples in the hovering position, especially when the temples are in the unfolded and retracted state. At this time, even if the glasses frame is taken alone, the temples will not shake.

[0029] In some embodiments, the damping member 3 is a metal member, a plastic member, or a composite material. Specifically, when the damping member 3 is a metal member, a self-lubricating metal such as brass can be selected to avoid noise or excessive damping caused by friction; when the damping member 3 is a composite material, a plastic material can be formed on the surface of the metal support member, and the plastic part is in contact with the elastic member to provide a damping effect.

[0030] In a preferred embodiment, the damping member 3 is a plastic member.

[0031] Compared with other materials, the use of plastic parts as the damping element 3 has the characteristic of 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 play a reinforcing role.

[0032] In one embodiment, the damping member 3 includes a clamping portion 32 and a first sealing ring 31, the clamping portion 32 is connected to the first sealing ring 31, the first sealing ring 31 is located between the first fastener 212 and the hinge plate 11 to seal the elastic mounting cavity 213, the outer wall of the clamping portion 32 abuts against the inner wall of the first fastener 212, and the inner wall of the clamping portion 32 abuts against the outer wall of the elastic member 5 to form a clamping prestress.

[0033] During the rotation of the temple, the position of the damping member 3 and the position of the hinge plate 11 are fixed to each other.

[0034] The first sealing ring 31 is used to seal the elastic safety cavity, thereby preventing external dust from entering the elastic safety cavity and ensuring that the elastic member 5 is not interfered with by external structures.

[0035] The method of abutting the clamping part 32 against the outer wall of the elastic member 5 to achieve damping has a longer service life, better stability and a wider installation tolerance. Because the elastic member 5 itself is elastic, by abutting the clamping part 32 with the elastic member 5, the clamping prestress between the elastic member 5 and the clamping part 32 can be kept in a relatively moderate state by relying on the elasticity of the elastic member 5, thereby avoiding the problem of severe wear caused by excessive pressure or too low damping caused by too low pressure. At the same time, after a certain wear occurs on the clamping part 32, a certain damping effect can be maintained by relying on the adaptive deformation of the elastic member 5. Compared with the method of directly contacting the damping member 3 with the rigid structure, the damping retention effect after wear is better, and it also has a higher dimensional tolerance during installation.

[0036] In one embodiment, there are multiple clamping portions 32, and the multiple clamping portions 32 are arranged on the first sealing ring 31 in a circumferential manner. The inner walls of the multiple clamping portions 32 are located on the same preset circle, and in a non-installed state, the radius of the preset circle is smaller than the outer diameter of the elastic member 5, so that the elastic member 5 is clamped by the multiple clamping portions 32 in the installed state. Prestress.

[0037] By providing a plurality of clamping portions 32 , the clamping prestress of the elastic member 5 in different directions can be balanced, thereby avoiding the problem of eccentric displacement of the elastic member 5 .

[0038] Specifically, in this embodiment, the number of the clamping parts 32 is two.

[0039] like Figure 3 As shown, in one embodiment, a slot 214 is provided in the first fastener 212, and the first end 51 of the elastic member 5 is embedded in the slot 214. The slot 214 fixes the first end 51 of the elastic member 5, and the second end 52 of the elastic member 5 is a free end. Figure 6As shown, the side wall of the hinge plate 11 is provided with a block 16. When the temple of the glasses is unfolded to approximately 90°, the second end 52 of the elastic member 5 abuts against the block 16 for limiting. During the process of the temple of the glasses being unfolded to approximately 90°, the damping member 3 and the hinge plate 11 are relatively fixed in position. At this time, since the first end 51 of the elastic member 5 is fixed relative to the first buckle 212, the first buckle 212 drives the elastic member 5 to rotate relative to the clamping portion 32. Therefore, the clamping portion 32 slides around the outer wall of the elastic member 5 and provides damping. When the temple of the glasses is further expanded outward from approximately 90°, the block 16 drives the second end 52 of the elastic member 5, and the first buckle 212 drives the first end 51 of the elastic member 5, so that the first end 51 and the second end 52 of the elastic member 5 are relatively close to each other, generating elastic force, thereby providing elasticity for the outward expansion of the temple of the glasses.

[0040] In one embodiment, a first hinge tube 12 and a second hinge tube 13 are respectively disposed on both sides of the hinge plate 11 , the first fastener 212 is rotatably sleeved on the first hinge tube 12 , and the second fastener 222 is rotatably sleeved on the second hinge tube 13 .

[0041] The first hinged tube 12 and the second hinged tube 13 are used to support the first fastener 212 and the second fastener 222, and this structure can realize the rotation function without setting a rotating shaft at the center position, avoiding the influence of the rotating shaft setting on the passing function. Under the premise of not affecting the function of the elastic member 5, a raised wall 17 can be set on the first hinged tube 12 and / or the second hinged tube 13 to improve its supporting strength. Furthermore, the raised wall 17 serves to limit the rotation of the damping member 3 relative to the hinge plate 11.

[0042] In one embodiment, a second sealing ring 4 is disposed between the second fastener 222 and the hinge plate 11 to seal the transfer cavity 224 .

[0043] The second sealing ring 4 is used to seal the transfer chamber 224 to prevent external dust from entering the transfer chamber 224 and ensure that the electrical connection wires therein are not interfered by external structures.

[0044] On the other hand, both the first connection part 1 and the second connection part 2 are metal parts. If the first connection part 1 and the second connection part 2 are in direct rigid contact, wear is likely to occur during long-term rotation, resulting in a decrease in the friction between the first connection part 1 and the second connection part 2, and there is a problem of structural instability. The first sealing ring 31 and the second sealing ring 4 are provided to avoid wear between the first connection part 1 and the second connection part 2. Since the first sealing ring 31 and the second sealing ring 4 are plastic parts, the surfaces thereof 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 the damping member 3 and the second sealing ring 4 separately has a better cost advantage, because the first connection part 1 and the second connection part 2 are usually integrally formed with the eyeglass frame and the eyeglass legs, respectively, and there is a large replacement cost.

[0045] In some embodiments, the elastic member 5 is selected from a metal shrapnel or a non-metal shrapnel, and the metal shrapnel is selected from one of a zirconium-based amorphous alloy shrapnel, a copper-based amorphous alloy shrapnel, an iron-based amorphous alloy shrapnel, a magnesium-based amorphous alloy shrapnel, and a titanium-based amorphous alloy shrapnel.

[0046] In a preferred embodiment, the elastic member 5 is selected from zirconium-based amorphous alloys.

[0047] The material strength of zirconium-based amorphous alloy is high, with a tensile strength of 800~1500MPa, 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 accessories and improving the comfort of the wearer. At the same time, the high strength of the material ensures that the glasses will not deform during long-term use, thereby improving the quality of the glasses. The Vickers hardness of zirconium-based amorphous alloy is 440~540Hv, far exceeding that of stainless steel and titanium alloy, and has less wear during use. It will not deform or lose elasticity even in long-term use. The elastic deformation rate of 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, comprising the elastic over-the-wire hinge for glasses, a glasses frame and glasses legs as described above, wherein the glasses frame is provided with a stud, one of the first connecting part 1 and the second connecting part 2 is connected to the stud, and the other of the first connecting part 1 and the second connecting part 2 is connected to the glasses legs.

[0049] 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 in the protection scope of the present invention.
