Description

Technical Field

[0001] This application belongs to the technical field of glasses. More specifically, it relates to a combination of glasses, temple arms and hinges, and spectacle hinges. Background Art

[0002] A pair of glasses includes a lens frame and temple arms. Usually, spectacle hinges are used to hinge the temple arms to the lens frame so that the temple arms can rotate between a closed position and an open position. When the temple arms are in the closed position, the temple arms are folded and retracted to the lens frame of the spectacle frame. When the temple arms are in the open position, the temple arms are approximately at a right angle to the lens frame to fit the user's face shape. Since the temple arms of the glasses extend in the front-back direction and are hung on the ears during use, the rotation of the temple arms between the closed position and the open position can be regarded as rotation around a vertical axis on a horizontal plane. When people take off or put on glasses, the most common accidental bending is to over-open the temple arms from the open position. If the temple arms are allowed to over-open at a large angle and then return to the normal use state, the spectacle frame can be effectively prevented from being irreversibly deformed, and the service life of the spectacle frame can be extended. Secondly, the accidental bending that will occur is that the temple arms will also be subjected to loads in a direction perpendicular to the above-mentioned horizontal plane, that is, loads in the up-down direction. If the temple arms are allowed to pivot and swing in the up-down direction and then return to the normal use state, this can effectively prevent the spectacle frame from being irreversibly deformed, and the service life of the spectacle frame can be extended.

[0003] The folding and rotation of the temple arms of existing glasses often use an elastic structure. Even when rotating between the closed position and the open position, the temple arms are elastically automatically reset to the closed position or the open position under the elastic force of the spring, which will bring a better use experience to the glasses user.

[0004] A spectacle hinge for spectacles disclosed in US Patent Document US10365501B2 and WIPO Document WO / 2021 / 114228A1 includes a guide body. Guide grooves are respectively provided on two opposite end faces of the guide body, and the length directions of the two guide grooves are perpendicular to each other. Two connecting pieces are provided and respectively extend into the two guide grooves and are hinged in the guide body. The two connecting pieces can be pivot axes for each other and swing in the corresponding guide grooves. Since the length directions of the two guide grooves are perpendicular to each other, the swinging directions of the two connecting pieces are perpendicular to each other. In order to achieve elastic recovery, springs and end face elements are respectively sleeved on the two connecting pieces, and the two end face elements are respectively connected to the temple and the spectacle leg of the spectacle frame. When the spectacle leg is in the open position, the end face of the temple end face element of the two end face elements tightly abuts one end face of the guide body, and the end face of the spectacle leg end face element tightly abuts the other end face of the guide body. This spectacle hinge is used in a spectacle frame, and its spectacle leg can achieve multi-directional rotation, including large-angle over-opening in the horizontal plane direction and large-angle rotation in the up-and-down direction, and can restore the spectacle leg to the open position or the closed position under the action of the spring.

[0005] However, an important drawback of this product is that when the spectacle leg rotates outward with excessive opening in the horizontal plane direction, the guide body rotates relative to the temple end face element, and the end face of the temple end face element tightly abuts and rotates and rubs against the outer side surface of the guide body under the action of the spring. As a spectacle product, the surface of the guide body will have a surface treatment layer such as an electroplating layer. After the spectacle leg rotates outward with excessive opening many times, the surface treatment layer on the outer side surface of the guide body will be worn due to friction. Since this is the rotation of the spectacle leg in the horizontal plane direction, which is a common rotation of the spectacle leg, this aggravates the wear of the surface treatment layer on the outer side surface of the guide body and damages the product quality.

[0006] Chinese Patent Document CN111796435A also discloses a hinge for spectacles, and the technology disclosed in this document also has the above-mentioned important drawback. Specifically, in the technical solution of Document CN111796435A, as shown in the attached Figure 36 component called the central member 2, which is equivalent to the guide body described in the aforementioned US Patent Document US10365501B2. When the spectacle leg rotates outward with excessive opening in the rotation direction between the closed position and the open position, the arc-transition end face C of the central block 2 abuts against the mating platform 7 of the spectacle leg connecting piece and rotates and rubs. After the spectacle leg rotates outward from the open position many times, the surface treatment layer on the outer side surface of the central block 2 including this arc-transition end face C will be worn due to friction. Similarly, this occurs in the common rotation of the spectacle leg, which aggravates the wear of the surface treatment layer on the outer side surface of the central block and damages the product quality.

[0007] Another important drawback exists in the technologies disclosed in the above-mentioned documents US10365501B2 and WO / 2021 / 114228A1, as well as the document CN111796435A, which is that the size of the hinge is relatively large. People generally hope that the glasses are lighter in weight, which requires that the cross-sectional size of the hinge cannot be thick. In the technical solution of the document CN111796435A, the adaptation platform 7 of the temple connecting member abuts against the lower end face of the central block 2. When the temple rotates in the rotation direction between the closed position and the open position and opens outward excessively, from the line of action of the force exerted on the central member 2 by the spring to the fulcrum where the initial relative rotation occurs between the two, there needs to be a lever arm size, and this lever arm size cannot be small. If it is small, it will make the temple too easy to rotate in the direction of opening outward excessively, and the temple cannot effectively clamp on the wearer's head. When the temple rotates outward at a large angle, such as when it opens outward excessively and is close to 90 degrees with the preset open position, in order to achieve elastic recovery to the preset open position, the arc transition end face C on one side of the lower end face of the central block 2 needs to have a relatively large width dimension in the cross-sectional direction of the hinge. That is, it is necessary to increase the dimension of the central block along the length direction of the B guiding groove. The non-small lever arm size plus the relatively large width dimension of the arc transition end face C thus results in a relatively large size in the cross-section of the hinge. For the same reason, the hinge structure of the glasses disclosed in the document US10365501B2 also results in a relatively large size in the cross-section of the hinge. Summary of the Invention

[0008] The purpose of the embodiments of the present application is to provide a pair of glasses, a combination of temple and hinge head, and a glasses hinge, so as to solve the problem that the guiding member of the glasses hinge in the prior art wears the outer surface layer when rotating between the open position and the closed position, and when rotating between the open position and the over-opened state.

[0009] To achieve the above purpose, the technical solution adopted in the embodiments of the present application is: to provide a glasses hinge, including:

[0010] A guiding member having a first end face and a second end face at opposite ends, a first guiding groove is provided on the first end face, a second guiding groove is provided on the second end face, the first guiding groove and the second guiding groove intersect perpendicularly, and the second guiding groove divides the groove bottom surface of the first guiding groove into a first sub-surface and a second sub-surface;

[0011] A first connecting member including a first connecting end and a fixed end connected to the first connecting end;

[0012] A second connecting member including a second connecting end, a supporting portion connected to the second connecting end, and a stopping portion provided on the supporting portion;

[0013] A holding member having an abutting surface for abutting against the guiding member, and a through cavity is provided in the holding member for the second connecting end to pass through and move; and,

[0014] A spring, with both ends elastically abutting against the holding member and the stopping portion respectively;

[0015] The first connecting end and the second connecting end are hinged within the guiding member and serve as rotation pivots for each other. The first connecting end can pivot along the first guiding groove, and the second connecting end can pivot along the second guiding groove;

[0016] Wherein, the first sub - surface includes a first inclined surface, and the first inclined surface extends obliquely in a direction towards the second end surface from one end far away from the second sub - surface to one end close to the second sub - surface;

[0017] The first connecting end is provided with:

[0018] A first positioning surface for adaptively abutting against the first inclined surface to position the first connecting end at the open position;

[0019] A second positioning surface for adaptively abutting against the first inclined surface to position the first connecting end at the closed position; and,

[0020] A third positioning surface for abutting against the second sub - surface when the first connecting end is positioned at the open position.

[0021] Another object of the embodiment of the present application is to provide a combination of temple and hinge, including a hinge, a temple and the spectacle hinge as described in the above - mentioned embodiment. The fixed end is connected to one of the hinge and the temple, and the holding member is connected to the other of the hinge and the temple.

[0022] Another object of the embodiment of the present application is to provide a pair of glasses, including a lens frame and temples, and further including the spectacle hinge as described in the above - mentioned embodiment to connect the temples to the spectacle frame.

[0023] One or more of the above - mentioned technical solutions in the embodiment of the present application, compared with the prior art, have at least one of the following technical effects:

[0024] On the one hand, for the spectacle hinge in the embodiment of the present application, since a first inclined surface is provided on the first sub-surface of the first guiding groove of the guiding member, the first inclined surface extends obliquely in a direction towards the second end surface from the end far away from the second sub-surface to the end close to the second sub-surface. Correspondingly, a first positioning surface is provided at the first connecting end for adaptively abutting against the first inclined surface to position the first connecting end at the open position, a second positioning surface is provided for adaptively abutting against the first inclined surface to position the first connecting end at the closed position, and a third positioning surface is provided for abutting against the second sub-surface when the first connecting end is positioned at the open position. The above settings enable the rotation of the spectacle hinge between the open position and the closed position to be carried out by the sliding of the first smooth transition surface formed between the first positioning surface and the second positioning surface on the first inclined surface. When the convex portion where the first smooth transition surface is located falls into the second guiding groove, the first connecting member is in the closed position. In this way, when the first connecting member rotates between the open position and the closed position, it will not cause jamming. Therefore, the rotation of the spectacle hinge with an elastic reset function between the open position and the closed position is realized by the first connecting end abutting against the first inclined surface in the guiding member. This enables the spectacle hinge to rotate between the open position and the closed position, and between the open position and the over-opened state, without wearing the outer surface layer of the guiding member.

[0025] On the other hand, since a first inclined surface is provided on the first sub-surface of the first guiding groove of the guiding member, the first inclined surface extends obliquely in a direction towards the second end surface from the end far away from the second sub-surface to the end close to the second sub-surface. As a result, the thickness of the bottom of the first guiding groove corresponding to the first sub-surface gradually decreases from the end far away from the second sub-surface to the direction of the second guiding groove. Thus, the thickness of the bottom of the first guiding groove at the end far away from the second sub-surface can be set larger to ensure the structural strength of the bottom of the first guiding groove and reduce the size of the guiding member in the length direction of the first guiding groove. Also, the thickness of the bottom of the first guiding groove at the position adjacent to the second guiding groove can be set smaller, so that the distance between the hinge joint of the first connecting end and the second connecting end and the second end surface is smaller. When the second connecting end makes a large-angle rotation of nearly 90 degrees relative to the first connecting end, the moment formed between the elastic acting force of the spring on the guiding member through the second connecting end and the abutting surface of the guiding member is larger. Therefore, when the moment is certain, the size of the guiding member in the length direction of the second guiding groove can be set smaller, thereby reducing the size of the guiding member, and further reducing the size and weight of the spectacle hinge. When applied to spectacles, it can ensure the wearing experience of the spectacles. Description of the Drawings

[0069] Please refer to Figures 1 to 10, a description is now given of the spectacle hinge 100 provided in the first embodiment of the present application. The spectacle hinge 100 includes a guide member 30, a first connecting member 10, a second connecting member 20, a resisting member 50, and a spring 40, where:

[0070] The guide member 30 has a first end face 301, a second end face 302, a first side face 303, a second side face 304, a third side face 305, and a fourth side face 306. The first end face 301 and the second end face 302 are opposite end faces on the guide member 30. The first side face 303 and the second side face 304 are opposite end faces on the guide member 30. The third side face 305 and the fourth side face 306 are opposite end faces on the guide member 30.

[0071] Corresponding to the groove structure, there are generally a depth direction, a width direction, and a length direction. Among them, the direction perpendicular to the two side walls of the groove structure is the width direction, the direction from the groove opening to the groove bottom is the depth direction, and the direction from one end of the groove to the other end is the length direction.

[0072] A first guide groove 31 is formed on the first end face 301. That is to say, the first guide groove 31 is provided on the guide member 30. The depth direction of the first guide groove 31 extends from the first end face 301 to the second end face 302, and the direction from the first side face 303 to the second side face 304 is the length direction of the first guide groove 31.

[0073] A second guide groove 32 is formed on the second end face 302. That is to say, the second guide groove 32 is also provided on the guide member 30. The depth direction of the second guide groove 32 extends from the second end face 302 to the first end face 301. That is to say, the direction from the third side face 305 to the fourth side face 306 is the length direction of the second guide groove 32.

[0074] The first guide groove 31 and the second guide groove 32 intersect perpendicularly. Then, the first guide groove 31 and the second guide groove 32 intersect inside the guide member 30. The length direction of the first guide groove 31 is perpendicular to the length direction of the second guide groove 32. In this way, the second guide groove 32 divides the bottom surface of the first guide groove 31 into two sub-bottom surfaces, namely a first sub-surface 35 and a second sub-surface 36. Correspondingly, the second guide groove 32 divides the bottom of the first guide groove 31 into two sub-bottoms, namely a first sub-bottom 37 and a second sub-bottom 38. The first sub-surface 35 is located on the first sub-bottom 37, and the second sub-surface 36 is located on the second sub-bottom 38.

[0075] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 10, the first connecting member 10 includes a first connecting end 11 and a fixed end 12. Among them, the first connecting end 11 is connected to the fixed end 12. The first connecting end 11 extends into the first guiding groove 31, and the fixed end 12 extends out of the first guiding groove 31. The first connecting end 11 can be driven by the fixed end 12 to rotate along the first guiding groove 31.

[0076] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , the second connecting member 20 includes a second connecting end 21, a supporting portion 22 and a stopping portion 23. The supporting portion 22 is connected to the second connecting end 21, and the stopping portion 23 is connected to the supporting portion 22. The second connecting end 21 extends into the second guiding groove 32, and the supporting portion 22 and the stopping portion 23 extend out of the second guiding groove 32. The second connecting end 21 can be driven by the supporting portion 22 to rotate along the second guiding groove 32.

[0077] The first connecting end 11 and the second connecting end 21 are hinged within the guiding member 30 and are mutually rotation pivots. The first connecting end 11 can pivot along the first guiding groove 31, and the second connecting end 21 can pivot along the second guiding groove 32.

[0078] In this embodiment, a first hinge hole 117 is formed on the first connecting end 11, and a second hinge hole 24 is provided on the second connecting end 21 to hinge the first connecting end 11 and the second connecting end 21. In this embodiment, the second hinge hole 24 is an oval or oblong hinge hole. Of course, the second connecting end 21 can also be arranged in a hook shape to hinge the first connecting end 11 and the second connecting end 21.

[0079] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6, the abutting member 50 is slidably mounted relative to the support portion 22, and the abutting member 50 is used to abut against the guide member 30. For example, an abutting surface 501 can be provided on the abutting member 50, and a through cavity 502 for the second connecting member to pass through and move is provided in the abutting member 50. In use, the support portion 22 of the second connecting member 20 passes through the through cavity 502, and the second connecting end 21 extends out of the abutting surface 501 of the abutting member 50 from the through cavity 502. The spring 40 is sleeved on the support portion 22, and both ends of the spring 40 elastically abut against the stop portion 23 and the abutting member 50 respectively, so that the abutting member 50 can slide along the support portion 22, and under the action of the elastic force of the spring 40; since the second connecting end 21 is hinged to the first connecting end 11, the second connecting end 21 elastically pulls the first connecting end 11 in the length direction towards the support portion 22, that is to say, a force towards the support portion 22 is applied to the first connecting end 11, so that the first connecting end 11 elastically abuts against the bottom of the first guiding groove 31. Therefore, under the action of the elastic force of the spring 40, the abutting surface 501 of the abutting member 50 abuts against the guide member 30. For the convenience of description, the force of the spring 40 on the first connecting end 11 is called the force of the spring 40.

[0080] Please refer to Figure 34 , when the spectacle hinge 100 is in use, the first connecting member 10 connects one of the temple 60 and the spectacle leg 70, and the abutting member 50 connects the other of the temple 60 and the spectacle leg 70, so as to realize the connection of the temple 60 of the spectacle frame and the spectacle leg 70 by the spectacle hinge 100. When the spectacle leg 70 is substantially perpendicular to the lens frame of the spectacle frame, the spectacle leg 70 is in the open state. At this time, the length direction of the first connecting member 10 is consistent with the depth direction of the first guiding groove 31, and the position where the first connecting member 10 is located at this time can be regarded as the open position. When the spectacle leg 70 is folded on the lens frame of the spectacle frame, the spectacle leg 70 is in the closed state. At this time, the length direction of the first connecting member 10 is substantially consistent with the length direction of the first guiding groove 31, and the position where the first connecting member 10 is located at this time can be regarded as the closed position. The first connecting member 10 rotates in the first guiding groove 31 from the closed position to the open position direction and exceeds the open position, that is to say, the first connecting member 10 rotates to the side of the open position away from the closed position, and the position where the first connecting member 10 is located at this time can be regarded as the over-open position.

[0081] The first sub-surface 35 includes a first inclined surface 351, and the first inclined surface 351 extends obliquely in the direction towards the second end surface 302 from the end far from the second sub-surface 36 to the end close to the second sub-surface 36. The first inclined surface 351 can be a plane or a curved surface, or a combined surface of a plane and a curved surface.

[0082] Please refer to Figure 4 、 Figure 9 、 Figure 10 , Figure 11and Figure 13 The first connection end 11 is provided with a first positioning surface 111, a second positioning surface 112 and a third positioning surface 113. The first positioning surface 111 is adapted to the first inclined surface 351 of the first sub-surface 35. When the first positioning surface 111 is in abutting engagement with the first inclined surface 351, the first connection end 11 can be positioned at the open position, that is, the first connecting member 10 is positioned at the open position. The second positioning surface 112 is also adapted to the first inclined surface 351. When the second positioning surface 112 is in abutting engagement with the first inclined surface 351, the first connection end 11 can be positioned at the closed position, that is, the first connecting member 10 is positioned at the closed position. The third positioning surface 113 is used to abut against the second sub-surface 36 when the first connection end is positioned at the open position. The first positioning surface 111 abuts against the first sub-surface 35, and the third positioning surface 113 abuts against the second sub-surface 36, so that the first connecting member 10 can be stably positioned at the open position.

[0083] In one embodiment, the first connection end 11 is provided with a guiding surface 114. When the first connecting member 10 rotates to a position past the open position, as Figure 18 shown, the guiding surface 114 abuts against the second sub-surface 36. At this time, due to the acting force of the spring 40 on the first connection end 11, the guiding surface 114 guides the first connection end 11 to return to the open position, so that the first connecting member 10 returns to the open position.

[0084] A first smooth transition surface 115 is provided between the first positioning surface 111 and the second positioning surface 112. That is to say, a convex portion 16 is formed between the first positioning surface 12 and the second positioning surface 14 of the first connection end 11, and the outer end surface of the flange of the convex portion 16 is the first smooth transition surface 115. When the first connection end 11 rotates between the open position and the closed position, it slides on the first inclined surface by the support of the first smooth transition surface 115, so that the first connecting member 10 can rotate smoothly.

[0085] In one embodiment, please refer to Figures 11 to 17 As shown, the first connection end 11 is restricted to rotate in the first guiding groove 31. The first connection end 11 pivots relative to the second connection end 21 to which it is hinged, and the first connection end 11 is subjected to the acting force of the spring 40 as shown by the arrow F1 from the second connection end 21. From Figure 11 the first connecting member 10 shown in the open position, to Figure 12 the position where the first connecting member 10 is initially rotated 5 degrees in the direction of the arrow M under the action of an external force as shown, and then to Figure 13 the position where it is rotated 45 degrees as shown, and then to Figure 14 the position where it is rotated 60 degrees as shown, during which the first smooth transition surface 115 of the convex portion 16 smoothly slides on the first inclined surface 351 without jamming. And when the first connecting member 10 is in the position asFigure 14 As shown, after reaching a position where it has rotated approximately 55 degrees from the open position to the closed position, under the action of the spring 40 in the direction of arrow F1, the first connecting member 10 can automatically rotate to Figure 15 the closed position shown. That is to say, the spectacle hinge can smoothly rotate from the open position to the closed position without jamming, and can also automatically reset to the closed position under the action of the spring after rotating through a certain angle.

[0086] When the spectacle hinge needs to rotate from Figure 15 the closed position shown to the open position, for example, when initially rotating to reach Figure 16 the state shown, this can also be smoothly carried out under the action of an external force without jamming. Because when the first connecting member 10 shown in Figure 15 is in the closed position, the second positioning surface 112 of the first connecting end 11 is adapted and abutted against the first inclined surface 351 of the guide member 30. At this time, the second positioning surface 112 and the first inclined surface 351 are parallel, and no part of the convex portion 16 is in the concave portion or groove portion of the first inclined surface 351 and its extended plane. This enables when the first connecting end rotates from the closed position to the open position, starting from the initial rotation angle as shown in Figure 16 , until the outer end surface of the convex portion 16 (that is, the first smooth transition surface 115) rotates onto the first inclined surface 351 and slides, it can all be smoothly carried out under the action of an external force without jamming. Then when continuing to rotate, under the action of an external force, the first connecting end 11 is always smoothly slid by the first smooth transition surface 115 on the first inclined surface 351. After rotating approximately 50 degrees, when reaching the position as shown in Figure 17 , under the action of the spring, the spectacle hinge can automatically rotate to Figure 11 the open position shown.

[0087] As described above, for the spectacle hinge of the embodiment of the present application, whether rotating from the open position to the closed position or from the closed position to the open position, it can be smoothly carried out without jamming; and it can automatically reset to the closed position or the open position under the action of the spring after rotating through a certain angle. This is one of the important beneficial effects of the technical solution of the present application.

[0088] To better illustrate the effect of the spectacle hinge 100 of the embodiment of the present application, the following will be described in combination with the comparative technical solutions related to the present application. Please refer to Figures 26 to 33 the spectacle hinge provided by the comparative technical solution shown. Assume a spectacle hinge of a comparative technical solution similar to Embodiment 1 of the present application, the difference of which is that a double-slot element 03 as shown in Figure 29 is used to replace the guide member 30 in Embodiment 1 of the present application, andFigure 28 A front connector 01 as shown replaces the first connector 10 in the first embodiment of the present application. Among them, the double-slot element 03 includes a front end face 034 and a rear end face 036, and an A guiding groove is provided on the front end face 034, and a B guiding groove is provided on the rear end face 036. The A guiding groove and the B guiding groove are vertically intersecting. The difference between the double-slot element 03 in this comparative technical solution and the guiding element 30 in the embodiment of the present application is that the two sub-bottom surfaces of the bottom surface 035 of the A guiding groove divided by the B guiding groove are both parallel to the rear end face 036, that is to say, the two sub-bottom surfaces of the bottom surface 035 of the A guiding groove divided by the B guiding groove are straight with an angle of 180 degrees between them. The difference between the front connector 01 and the first connector 10 in the embodiment of the present application is that when the spectacle hinge is in the open position state, a front flat surface 011 at the front end of the front connector 01 abuts against the two sub-bottom surfaces of the bottom surface 035 of the A guiding groove, and when the spectacle hinge is in the closed position state, a closed side flat surface 012 at the front end of the front connector 01 abuts against the two sub-bottom surfaces of the bottom surface 035 of the A guiding groove. The closed side flat surface 012 and the front flat surface 011 form an angle of about 90 degrees, and a convex position portion 014 with a smooth transition is also formed between the front flat surface 011 and the closed side flat surface 012 of the front connector 01. Please refer to Figures 30 to 33 , when the spectacle hinge rotates from Figure 30 the open position as shown to Figure 33 the closed position as shown, for example, when rotating 30 degrees to reach Figure 31 the state as shown before, this can be carried out under the action of an external force. However, when rotating about 40 degrees to reach Figure 31 the state as shown, the convex position portion 014 starts to slide into the recess formed between the two sub-bottom surfaces of the bottom surface 035 of the A guiding groove under the action of the spring as shown by the arrow F2, and then at a position where it has rotated about 65 degrees, such as Figure 32 the state as shown, both sides of the convex position portion 014 fall into the recess between the two sub-bottom surfaces of the bottom surface 035, and at this time the convex position portion 014 is still under the action of the spring tension as shown by the arrow F2, so the rotation gets stuck and cannot smoothly rotate to Figure 33 the closed position as shown. Similarly, when the spectacle hinge of this comparative technical solution rotates from the closed position to the open position, it will also get stuck and cannot smoothly complete the rotation. Combining the foregoing, the spectacle hinge in the embodiment of the present application overcomes the defects in the comparative technical solution.

[0089] Another important aspect, in one embodiment, please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7, the second end face 302 is a flat surface. Guide arcs 33 connected to the second end face 302 are respectively provided on the opposite sides of the guide member 30 along the length direction of the second guide groove 32. That is to say, the third side face 305 and the second end face 302 are smoothly transitioned through the guide arc 33, and the fourth side face 306 and the second end face 302 are also smoothly transitioned through the guide arc 33. In this way, when the abutting surface 501 of the abutting member 50 is adapted to abut against the second end face 302, the second connecting member 20 can be positioned, and this position can be regarded as the set positioning. The guide arc 33 is used to guide the second connecting member 20 and the abutting member 50 to return to the set positioning state when the second connecting member 20 rotates along the second guide groove 32 and drives the abutting member 50 to rotate relative to the guide member 30. When the second connecting member 20 rotates along the second guide groove 32, it drives the abutting member 50 to rotate relative to the guide member 30. At this time, the contact point Q1 between the guide member 30 and the abutting surface 501 is located on the guide arc 33.

[0090] Since the abutting surface 501 on the abutting member 50 elastically abuts against the guide member 30, and the abutting member 50 is sleeved on the second connecting member 20. In this way, when the second connecting end 21 of the second connecting member 20 rotates along the second guide groove 32, the abutting member 50 rotates with the second connecting member 20. The direction of the force of the spring 40 on the first connecting end 11 is along the direction of the supporting portion 22, and is transmitted to the guide member 30 through the first connecting end 11, so that the guide arc 33 of the guide member 30 abuts against the abutting surface 501 of the abutting member 50. After the abutting member 50 rotates relative to the guide member 30 with the second connecting member 20, the contact point Q1 between the abutting surface 501 and the guide member 30 will also change accordingly. As the rotation angle increases, the contact point Q1 between the abutting surface 501 and the guide member 30 will deviate from the straight line where the acting force F1 is located with an increasing distance, thus forming a restoring force arm, so that the second connecting member 20 and the abutting member 50 are automatically reset.

[0091] Please refer to Figures 4 to 9, since the first sub - surface 35 includes a first inclined surface 351 which extends and inclines in the direction towards the second end - face 302 from the end far away from the second sub - surface 36 to the end close to the second sub - surface 36. That is to say, in the direction from the first side - face 303 to the second guiding groove 32, the distance from the first inclined surface 351 to the second end - face 302 gradually decreases. The distance from the first sub - surface 35 to the second end - face 302 is the thickness of the first sub - bottom 37. Then the thickness of the first sub - bottom 37 gradually decreases along the first inclined surface 351 in the direction from the first side - face 303 to the second guiding groove 32. In this way, the thickness of the part of the first sub - bottom 351 close to the first side - face 303 can be set larger to ensure the structural strength of the first sub - bottom 351, and further ensure the structural strength of the bottom of the first guiding groove 31. In this way, the dimension H1 of the guiding member 30 in the length direction of the first guiding groove 31 can be made smaller. That is to say, the distance between the first side - face 303 and the second side - face 304 can be set smaller to reduce the size of the guiding member 30.

[0092] In addition, the thickness of the first sub - bottom 351 gradually decreases in the direction from the first side - face 303 to the second guiding groove 32, and the thickness of the part of the first sub - bottom 37 close to the first side - face 303 can be set larger. That is to say, in this way, while ensuring the structural strength of the first sub - bottom 35, the distance from the end of the first sub - surface 35 close to the second guiding groove 32 to the second end - face 302 can be set smaller, so that the hinge joint of the first connecting end 11 and the second connecting end 21 is closer to the second end - face 302. In this way, as the rotation pivot of the second connecting member 20, that is, the distance between the hinge joint of the first connecting end 11 and the second connecting end 21 and the second end - face 302 is closer. Since when the second connecting member 20 drives the abutting member 50 to rotate, the acting force of the spring 40 is always in the length direction of the supporting part 22, and the abutting surface 501 of the abutting member 50 and the contact point Q1 of the guiding member 30 is the pivot point for the guiding member 30 to rotate relative to the second connecting member 20. When the second connecting member 20 rotates 90 degrees, the distance T1 between the contact point Q1 of the abutting surface 501 and the guiding member 30 and the acting - force line of the acting force F1 of the spring 40 reaches the maximum. And when the distance between the hinge joint of the first connecting end 11 and the second connecting end 21 and the second end - face 302 is closer, when the dimension W1 of the guiding member 30 in the length direction of the second guiding groove 32 is certain, the distance between the contact point Q1 of the abutting surface 501 and the guiding member 30 and the acting - force line of the acting force F1 of the spring 40 will be larger. Therefore, it should be understood that when the torque required for the second connecting member 20 to reset is certain, the distance between the contact point Q1 of the abutting surface 501 and the guiding member 30 and the acting force F1 of the spring 40 can be set smaller. Correspondingly, the dimension W1 of the guiding member 30 in the length direction of the second guiding groove 32 can be set smaller. Therefore, the size of the guiding member 30 can be made smaller, and further the size of the spectacle hinge 100 can be reduced. When applied to spectacles, the wearing experience of users can be improved.

[0093] In one embodiment, refer to Figure 1 、 Figure 4 and Figure 5 , the spring 40 can be sleeved on the support portion 22 to position and install the spring 40. Of course, other methods can also be used to support the spring 40, such as setting a slot on the support portion 22 and placing the spring 40 in the slot.

[0094] In one embodiment, the first positioning surface 111 and the second positioning surface 112 can be a plane or a curved surface to facilitate the adaptation and abutment with the first inclined surface 351, which facilitates stably positioning the first connecting member end 11 at the open position or the closed position when adapting and abutting with the first inclined surface 351, and facilitates the first connecting end 11 to have the technical effect of not jamming as described above when pivoting along the first guiding groove 31, and the technical effect of automatically resetting to the closed position or the open position under the action of the spring force after rotating a certain angle.

[0095] In one embodiment, the third positioning surface 113 can be a plane or a curved surface to facilitate the adaptation with the second sub - surface.

[0096] In one embodiment, the third positioning surface 113 can also be an arc - shaped surface smoothly connected by a plurality of arc surfaces; since when the first positioning surface 111 abuts against the first inclined surface 351, the third positioning surface abuts against the second sub - surface, the first connecting end 11 can be positioned at the open position. The third positioning surface 113 is set as an arc - shaped surface smoothly connected by a plurality of arc surfaces, which facilitates guiding the first connecting member 10 back to the open position when the first connecting member 10 is over - opened. It can be understood that the third positioning surface 113 can also be an arc surface, which can also guide the first connecting member 10 back to the open position when the first connecting member 10 is over - opened.

[0097] In one embodiment, the third positioning surface 113 is a part of the guiding surface 114, that is to say, at this time, it is equivalent to not setting the third positioning surface 113, only setting the guiding surface 114. The first connecting end 11 is positioned at the open position by the first positioning surface 111 abutting against the first sub - surface 361 and the guiding surface 114 abutting against the second sub - surface 362; when the first connecting member 10 rotates to the over - opened position, the guiding surface 114 still abuts against the second sub - surface 362, and under the action of the spring 40, the guiding surface 114 guides the first connecting end 11 to return to the open position so that the first connecting member 10 returns to the open position.

[0098] In one embodiment, a second smooth transition surface 116 is provided between the first positioning surface 111 and the third positioning surface 113 to avoid interfering with the rotation of the first connecting end 11 and facilitate the processing and manufacturing of the first connecting end 11.

[0099] In one embodiment, referring to Figure 4 , Figure 9 , Figure 11 , the second sub-surface 36 includes a second inclined surface 361, which extends obliquely in a direction towards the second end surface 302 from one end far away from the first sub-surface 35 to one end close to the first sub-surface 35. That is to say, in the direction from the second side surface 304 to the second guiding groove 32: the distance from the second sub-surface 36 to the second end surface 302 gradually decreases, and the distance from the second sub-surface 36 to the second end surface 302 is also the thickness of the second sub-bottom 38. Then, the thickness of the second sub-bottom 38 gradually decreases in the direction from the second side surface 304 to the second guiding groove 32. In this way, the thickness of the part of the second sub-bottom 352 close to the second side surface 304 can be set larger to ensure the structural strength of the second sub-bottom 38. Combining with the setting of the first sub-bottom 37 described above, the dimension H1 of the guiding member 30 in the length direction of the first guiding groove 31 can be made smaller. That is to say, the distance between the first side surface 303 and the second side surface 304 can be set smaller to reduce the dimension of the guiding member 30. The second inclined surface 361 can be a plane, a curved surface, or a combined surface of a plane and a curved surface.

[0100] Gradually reducing the thickness of the second sub-bottom 38 in the direction from the second side surface 304 to the second guiding groove 32 can cooperate with the first sub-bottom 351 to form a V-shaped groove structure to better position the first connecting member 10 in the open position.

[0101] In one embodiment, the inclination of the first inclined surface 351 and the inclination of the second inclined surface 361 can be set to be symmetrical about the second guiding groove 32. That is to say, the inclination of the first inclined surface 351 is set to be equal to the inclination of the second inclined surface 361. Of course, the inclination of the first inclined surface 351 and the inclination of the second inclined surface 361 can also be set asymmetrically.

[0102] To better illustrate the effect of the spectacle hinge 100 according to the embodiment of the present application, the following will further explain in combination with the above-mentioned comparative technical solution. Refer to Figures 26 to 33The comparative technical solution shown. The difference between the comparative technical solution and the embodiment of the present application is that in the comparative technical solution, the groove bottom surface 035 of the A guiding groove of the double groove element 03 is a plane, and the thicknesses of the two sub-bottoms of the groove bottom surface 035 of the A guiding groove divided by the B guiding groove are equal everywhere. Thus, when the spectacle hinge is in the open position state, a front-end plane 011 is provided on the front end of the front connecting member 01 to abut against the two sub-bottom surfaces of the groove bottom surface 035 of the A guiding groove, so as to position the front-end plane 011 in the open position; when the spectacle hinge is in the closed position state, a closed-side plane 012 at the front end of the front connecting member 01 abuts against the two sub-bottom surfaces of the groove bottom surface 035. When the front connecting member 01 rotates between the open position and the closed position, the outer edge surface of the convex portion 014 formed between the front-end plane 011 and the closed-side plane 012 abuts against the groove bottom surface 035 for movement.

[0103] In the embodiment of the present application, the thickness of the first sub-bottom 351 near one end of the second guiding groove 32 is L1. In the comparative technical solution: since the thicknesses of the two sub-bottoms of the groove bottom surface 035 are equal everywhere, in order to ensure the structural strength of the bottom of the A guiding groove, the thickness L2 of the two sub-bottoms of the groove bottom surface 035 needs to be set larger, that is, L2 > L1.

[0104] Please refer to Figure 6 , in the embodiment of the present application, the acting force F1 of the spring 40 is along the length direction of the supporting portion 22, the distance from the acting force F1 of the spring 40 to the second end face 302 is D1. When the second connecting member 20 rotates along the second guiding groove 32, the contact point Q1 between the guiding arc surface 33 and the abutting surface 501 is the rotation fulcrum of the guiding member 30 relative to the second connecting member 20. When the second connecting member 20 rotates 90 degrees, the distance from the contact point Q1 to the acting force F1 of the spring 40 is T1, and the dimension of the guiding member 30 along the length direction of the second guiding groove 32 is W1.

[0105] Please refer to Figure 26 , in the comparative technical solution, the acting force F2 of the spring 40 is along the length direction of the supporting portion 22, the distance from the acting force F2 of the spring 40 to the second end face 034 is D2. When the second connecting member 20 rotates 90 degrees relative to the front connecting member 10, the distance from the double groove element 03 and the contact point Q2 to the acting force F2 of the spring 40 is T2, and the dimension of the double groove element 03 along the length direction of the A guiding groove is W2.

[0106] Since L2 > L1, in the embodiments of the present application, the second connection end 21 will be closer to the second end face 302, that is, D1 < D2. When the dimension of the guide member 30 along the length direction of the second guide groove 32 is fixed, and when the second connecting member 20 and the abutting member rotate at a large angle relative to the guide member, for example, when the second connecting member 20 rotates 90 degrees, then in the embodiments of the present application, the distance from the contact point Q1 to the acting force F1 of the spring 40 will be greater, that is, T1 > T2. Correspondingly, in the embodiments of the present application, the restoring moment formed by F1 * T1 of the second connecting member 20 is greater than the restoring moment formed by F2 * T2 of the second connecting member 20 in the comparative embodiment. Then it should be understood that when the required restoring moment of the second connecting member 20 in the embodiments of the present application is similar to or equal to the required restoring moment of the second connecting member 20 in the comparative embodiment, the dimension W1 of the guide member 30 along the length direction of the second guide groove 32 in the embodiments of the present application can be set smaller, that is, W1 < W2.

[0107] As can be seen from the above, in the embodiments of the present application, the dimension H1 of the guide member 30 along the length direction of the first guide groove 31 and the dimension W1 along the length direction of the second guide groove 32 can be set smaller to reduce the dimension of the guide member 30. Correspondingly, the dimension of the spectacle hinge 100 can be set smaller.

[0108] Through experimental tests, the guide member 30 in the embodiments of the present application and the double-slot element 03 in the comparative technical solution can generally be made of metal materials. Even if a metal material with good strength and hardness, such as stainless steel, is selected, the distance L2 from the bottom surface 035 of the A guide groove of the double-slot element 03 to the front end surface 034 cannot be less than 0.5 mm, otherwise the double-slot element 03 will be deformed due to insufficient strength and cannot work properly. In the embodiments of the present application, the minimum value of the thickness L1 of the first sub-bottom 351 near one end of the second guide groove 32 can be set to be less than or equal to 0.3 mm, so that the hinged joint of the first connection end 11 and the second connection end 21 is closer to the second end face 302.

[0109] In one embodiment, the first inclined surface 351 is the whole of the first sub-surface 35, that is, the first sub-surface 35 is wholly the first inclined surface 351. It can be understood that a partial area of the first sub-surface 35 is the first inclined surface 351.

[0110] In one embodiment, the second inclined surface 361 is the whole of the second sub-surface 36, that is, the second sub-surface 36 is wholly the second inclined surface 361. It can be understood that a partial area of the second sub-surface 36 is the first inclined surface 361.

[0111] Please refer to Figures 19 to 25 , the differences between the spectacle hinge 100 of this embodiment and the spectacle hinge 100 of the first embodiment are as follows:

[0112] In this embodiment: The second sub-surface 36 of the first guiding groove 31 of the guiding member 30 is a plane parallel to the second end surface 302. That is to say, the thickness of each part of the second sub-bottom 38 is consistent.

[0113] As Figure 21 shown, when the first connecting member 10 is in the open position, it is abutted by the first positioning surface 12 against the first inclined surface 351, and abutted by the third positioning surface 113 against the second sub-surface 36 to stably position the first connecting end 11 in the open position; As Figure 23 shown, when the first connecting member 10 is in the closed position, it is abutted by the second positioning surface 112 against the first inclined surface 351 to stably position the first connecting member 10 in the closed position. When the first connecting member 10 needs to rotate from Figure 21 the open position shown to Figure 23 the closed position shown, similar to the situation in the first embodiment, during this process, the first smooth transition surface 115 of the convex portion 16 smoothly slides on the first inclined surface 351 without jamming. And when the first connecting member 10 rotates about 55 degrees from the open position to the closed position as shown in Figure 22 , under the action of the spring 40 in the direction of arrow F1, the first connecting member 10 can automatically rotate to Figure 23 the closed position shown. When the spectacle hinge rotates from Figure 23 the closed position shown to the open position, for example, when it initially rotates 5 degrees to reach Figure 24 the state, this can also be smoothly carried out under the action of an external force without jamming, which is the same as the situation described in the previous first embodiment. And it can automatically reset to the closed position under the action of the spring 40 after rotating a certain angle. When the first connecting member 10 rotates past the open position, as Figure 25 shown, the guiding surface 114 abuts against the second sub-surface 36, and the first connecting member 10 can be driven by the action of the spring 40 to reset to the open position.

[0114] In another important aspect, in the second embodiment of the present application, since the first inclined surface 351 is provided on the first sub-surface 35, the thickness of the first sub-bottom 37 near the first side surface 303 can be set larger to enhance the structural strength of the bottom of the entire first guiding groove 31. Then, the thickness of the first sub-bottom 37 near one end of the second guiding groove 32 can be set smaller, and at the same time, the thickness of the second sub-bottom 38 can also be set smaller accordingly, so that the hinge joint of the first connecting end 11 and the second connecting end 21 is closer to the second end surface 302. In this way, as the rotation pivot of the second connecting member 20, that is, the distance between the hinge joint of the first connecting end 11 and the second connecting end 21 and the second end surface 302 is closer.

[0115] Please refer to Figure 34, an embodiment of the present application also discloses an assembly of a temple and a hinge endpiece. The assembly of the temple and the hinge endpiece includes a hinge endpiece 60, a temple 70, and an eyeglass hinge 100. The hinge endpiece is a common name in the eyeglass industry. It is the end piece located on both outer sides of the lens frame. In a pair of eyeglasses, one end of the hinge endpiece is connected to the lens frame, or mounted on the lens frame, or integrated with the lens frame, and the other opposite end of the hinge endpiece is connected to the eyeglass hinge. In this embodiment, the eyeglass hinge can be the eyeglass hinge 100 described in the above Embodiment 1 or Embodiment 2. The fixed end 12 of the eyeglass hinge 100 is connected to the hinge endpiece 60, and the abutting member 50 of the eyeglass hinge 100 is connected to the temple 70 to achieve the hinged connection between the temple 70 and the hinge endpiece 60. The assembly of the temple and the hinge endpiece uses the eyeglass hinge 100 of the above embodiment, which can realize the rotation of the temple 70 between the open state and the closed state, and can make the temple 70 automatically return to the open state when it is over-opened. It can also make the temple 70 automatically reset and align when rotating in the up and down directions. In addition, the size of the eyeglass hinge 100 can be made smaller, and the size and weight of the corresponding eyeglass frame can be made smaller, improving the user's wearing experience. It can be understood that the abutting member 50 of the eyeglass hinge 100 can also be connected to the hinge endpiece 60, and the fixed end 12 of the eyeglass hinge 100 can be connected to the temple 70 to achieve the hinged connection between the temple 70 and the hinge endpiece 60.

[0116] In one embodiment, a receiving hole (not shown in the figure) can be provided in the hinge endpiece 60 to insert the fixed end 12 into the receiving hole to be connected to the hinge endpiece 60.

[0117] In one embodiment, please refer to Figure 34 , the eyeglass hinge 100 further includes an end element 80. The end element 80 includes an end platform 81 and a fixing sleeve 82. The fixing sleeve 82 is connected to the end platform 81. An assembly hole 801 is provided in the end element 80 to assemble the fixed end 12 therein.
