Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to its eyeglasses hinge structure. Background Technology

[0002] Existing eyeglass structures typically include a frame, a toe box, and temples. The temples are connected to the toe box via a hinge structure to enable their opening and closing. In existing technology, the hinge structure of the temples generally involves a slot at the end of the toe box, with the hinged end of the temple rotatably positioned within the slot. A screw passes through the temple and toe box to achieve a rotatable hinged connection. Although this structure is widely used, this traditional hinge method has a relatively fixed structural form and component arrangement. To ensure connection strength and stability, a certain structural thickness must usually be maintained, making it difficult to further reduce the volume of the hinge area, thus limiting the development of eyeglasses towards a thinner and lighter overall design. Utility Model Content

[0003] Therefore, it is necessary to provide a simplified eyeglass hinge structure that reduces overall thickness and facilitates assembly, addressing the problem that the hinge structure is too thick and difficult to make thinner.

[0004] A glasses hinge structure, comprising:

[0005] The base has a groove at one end and a temple at the other end. The groove is recessed along the thickness direction of the base, so that the base is divided into two mutually spaced ends at that end.

[0006] The movable body is slidably disposed within the groove; and

[0007] The base has a flange at one end, which is inserted into the groove along the extension direction of the groove and can abut against the movable body. The flange and the two ends of the base are rotatably connected by a common rotation axis, which extends along the width direction of the base.

[0008] The aforementioned eyeglass hinge structure utilizes a base with an internal groove at the temple end, a slidable movable body arranged within the groove, and a flange at the temple end inserted into the groove. The flange and the two ends of the base share a common axis of rotation for hinge engagement. Compared to the commonly used external multi-section hinge block structure in the prior art, the hinge component of this invention is primarily housed within the space defined by the temple contour. The hinge position does not require an additional protruding hinge block in the thickness direction, thereby reducing the overall thickness at the connection between the frame and the temple, resulting in a flatter and thinner appearance for the eyeglasses. Furthermore, the base, movable body, and flange can all adopt a flat, sheet-like or strip-like structure. Combined with the guiding and limiting effect of the groove, this reduces the number of parts while ensuring rotational stability, facilitating modular assembly and subsequent replacement, and improving the assembly convenience and reliability of the hinge structure. In one embodiment, the groove extends through the thickness direction of the base; and / or

[0009] The outer surface of the movable body is provided with a patterned structure for increasing friction or decorative effect.

[0010] In one embodiment, a first mating member is provided on the groove wall, and a second mating member is provided on the movable body, wherein the first mating member and the second mating member slide relative to each other.

[0011] In one embodiment, the first mating member is a groove body provided on the wall of the slide groove, and the second mating member is a protrusion provided on opposite sides of the movable body, the protrusion being slidably accommodated in the groove body.

[0012] In one embodiment, the first mating member is a protrusion provided on the wall of the slide groove, and the second mating member is a groove provided on opposite sides of the movable body, the groove slidably accommodating the protrusion.

[0013] In one embodiment, an elastic element disposed within the slide groove is further included, the elastic element abutting against the movable body and the bottom wall of the slide groove respectively.

[0014] In one embodiment, the movable body has a first positioning hole at one end facing away from the flange for accommodating one end of the elastic member. The first positioning hole is disposed in the end of the movable body or its protruding extension.

[0015] In one embodiment, a second positioning hole is provided on the bottom wall of the slide, and the other end of the elastic element is inserted into the second positioning hole.

[0016] In one embodiment, the flange protrudes outward from one end of the base, and lateral clearance portions are formed on both sides of the flange to make way for the two ends of the base.

[0017] In one embodiment, the end of the flange has a peripheral profile consisting of a plurality of interconnected edge segments forming an angled structure between the edge segments. Attached Figure Description

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] An eyeglass includes a frame, temples 200, and an eyeglass hinge structure 100 for connecting the frame and temples 200. For ease of explanation, the following description uses one side of the hinge assembly as an example; the structure on the other side may be the same or symmetrically arranged.

[0035] Please see Figures 1 to 11 In one embodiment, the eyeglass hinge structure 100 includes a base 1, a movable body 2, and a head 3.

[0036] The base 1 is fixed or integrally disposed on the end of the temple 200 near the frame. The end of the base 1 near the frame is a free end, which is provided with a groove 11. The groove 11 is recessed along the thickness direction of the base 1, so that the end of the base 1 is divided into two mutually spaced ends, and a gap is formed between the two ends for inserting the head 3.

[0037] The movable body 2 is slidably disposed within the groove 11. The movable body 2 can be integrally formed in the shape of a strip or sheet, and its thickness dimension matches the depth of the groove 11, allowing the movable body 2 to slide back and forth within the groove along its extension direction. In this embodiment, the groove 11 can be a blind groove structure, or it can extend through the thickness direction of the base 1 to facilitate processing and reduce weight; both forms are optional solutions of this utility model.

[0038] The temple 3 is located at the end of the frame, with a flange 31 at the end furthest from the frame. The flange 31 is inserted into the slide groove 11 along its extension direction, and the end face of the flange 31 can abut against the end face of the movable body 2, at which time the temple 200 is unfolded relative to the frame. The flange 31 and the two ends of the base 1 are connected by a common axis of rotation, which extends along the width direction of the base 1.

[0039] During assembly, the movable body 2 is first inserted into the groove 11 of the base 1, and then the flange 31 of the temple head 3 is inserted into the groove 11. Fasteners 4 (such as screws) are used to pass through the two ends of the base 1 and the flange 31 to form a rotating connection, thus completing the hinge connection between the frame and the temple 200. Since the axis of rotation is arranged along the width direction of the base 1, the base 1, the movable body 2, and the temple head 3 can all adopt a flat structure, so that the hinge assembly occupies less space in the thickness direction, which is conducive to the overall thin and light design of the glasses.

[0040] With the above structural arrangement, the flange 31, movable body 2, and base 1 end of the eyeglass hinge structure 100 are mainly housed within the contour range of the temple 200 end. The hinge area does not require additional protruding hinge blocks in the thickness direction. Combined with the flat structural design of each component, the overall thickness at the hinge point can be effectively reduced, making the entire pair of eyeglasses thinner and more aesthetically pleasing. Simultaneously, since the slide groove 11 provides a clearly defined assembly position, the movable body 2 can be pre-assembled within the base 1, providing abutment and limiting for the flange 31 of the temple 3. The flange 31 then forms a rotatable connection with the end of the base 1 via fasteners 4, thereby simplifying the assembly process.

[0041] This embodiment further explains the guiding fit between the slide 11 and the moving body 2.

[0042] Please see Figure 4 and Figure 10 In one embodiment, groove structures are formed on the opposite side walls of the groove 11 along the extension direction of the groove, serving as the first mating parts 12; outwardly protruding ribs are formed on the opposite outer surfaces of the movable body 2, serving as the second mating parts 21. During assembly, the second mating parts 21 are slidably accommodated within the first mating parts 12, thereby obtaining stable linear guidance within the groove 11 and preventing the movable body 2 from swaying in the width or thickness direction.

[0043] Please see Figure 5 , Figure 6 and Figure 11 In another form, protrusions along the extension direction of the slide groove are formed on the opposite sides of the slide groove 11 as first mating parts 12, while grooves are formed on the opposite sides of the movable body 2 as second mating parts 21.

[0044] The two structures mentioned above can be chosen according to the differences in mold or processing technology. The cross-section of the groove and the convex strip can be rectangular, trapezoidal or a composite shape with rounded corners, without limitation.

[0045] Please see Figures 4 to 6 In another embodiment, the slide groove 11 is provided with an elastic element 5, preferably a metal helical compression spring, but a leaf spring or elastic rubber element may also be used as needed. One end of the elastic element 5 abuts against the end of the movable body 2 facing away from the head 3, and the other end abuts against the bottom wall of the slide groove 11, so that the movable body 2 is kept in a pre-tightened state facing the flange 31 under the action of the elastic element 5.

[0046] To prevent displacement of the elastic element 5 during compression and reset, a first positioning hole 22 is provided at one end of the movable body 2 facing away from the flange 31 to accommodate one end of the elastic element 5. The first positioning hole 22 can be directly formed in the end body of the movable body 2, or it can be arranged in the rearward or downward protruding extension of the end of the movable body 2. Through the limiting effect of the first positioning hole 22, one end of the elastic element 5 can be reliably held in the central area of ​​the movable body 2, avoiding deviation.

[0047] In a further embodiment, a second positioning hole 13 may be provided on the bottom wall of the slide groove 11 for accommodating the other end of the elastic member 5. The two ends of the elastic member 5 are respectively inserted into the first positioning hole 22 and the second positioning hole 13, so that the elastic member 5 is more clearly constrained in the axial direction, which facilitates assembly and positioning, and at the same time prevents the elastic member 5 from shifting during long-term use, thereby improving the reliability and service life of the hinge mechanism.

[0048] During the opening and closing of the glasses, the temple 3 and the base 1 rotate relative to each other around the rotation axis. The flange 31 drives the movable body 2 to compress or release the elastic element 5, thereby providing a certain damping and positioning effect near the two extreme positions of opening and folding, so that the temple 200 can maintain a relatively stable angle in both the wearing and folding states, and is not easy to loosen.

[0049] In this embodiment, the structural morphology of the flange 31 at the end of the head 3 is further explained.

[0050] The end of the flange 3 facing the base 1 protrudes outward to form a flange 31. The middle part of the flange 31 is used to insert into the sliding groove 11 and abut against the movable body 2. On the side of the flange 31 near the end of the base 1, lateral clearance portions 32 are formed on both sides of the flange 31. The lateral clearance portions 32 can be partially recessed, necked, or chamfered. When the flange 31 is inserted into the sliding groove 11 and forms a rotational engagement with the two ends, the lateral clearance portions 32 provide lateral clearance space for the rotation of the ends, avoiding interference with the ends when the flange 3 rotates to its limit angle. At the same time, it can also form a limiting surface to improve the stability of the rotational connection.

[0051] Please see Figure 1 , Figure 4 , Figure 8 and Figure 9 To further enhance the reliability of the fit, the end of flange 31 can be designed as an outer contour composed of multiple interconnected edge segments, with angled structures formed between the edge segments. The end of flange 31 can be a right-angled end, or a polygonal or semi-polygonal end, such as a structure similar to a semi-hexagon. The polygonal angled design increases the contact boundary and creates a certain anti-rotation tendency. Combined with the pre-tightening of elastic element 5, it makes the temple 200 less likely to rotate on its own within the commonly used angle range, reducing the feeling of looseness.

[0052] Please see Figures 7 to 9 Based on the above structure, to adapt to different product styles or enhance the tactile feel, the outer surface of the movable body 2 can be provided with a patterned structure 23 as needed, such as lines, checks, dots, or other decorative patterns. The patterned structure 23 can not only enhance the friction when the user touches the hinge, making folding and unfolding operations easier, but also serve as a visual decorative element that echoes the overall shape of the temple 200.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications, substitutions, and improvements without departing from the concept of this utility model, and these should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the claims.
