Description

Technical Field

[0001] This utility model relates to the technical field of eyeglasses, specifically to a folding component for eyeglasses. Background Technology

[0002] Eyeglasses are items used to improve vision, protect the eyes, or as a fashion accessory. Traditional eyeglasses typically consist of two frames (also called eyeglasses), two temples, lenses, and nose pads. The inner ends of the two frames are connected by a crossbeam, and the outer ends of the two frames are connected to the front ends of the two temples.

[0003] In traditional eyeglasses, the front of the temples and the outer end of the frame are usually rotatably connected. This allows the two temples to be rotated inward to the back of the frame when the eyeglasses are not in use, so that the two temples can be folded. This helps to reduce the space occupied by the eyeglasses and makes them convenient to carry and store.

[0004] In fact, there are also eyeglasses with an even higher degree of folding available on the market. This type of eyeglasses is based on the traditional eyeglass structure mentioned above, but the bridge and temples are also designed to be foldable. Specifically, the bridge and temples of the eyeglasses include at least one rotating node. When the eyeglasses are not in use, the frame and temples can be folded through the rotating nodes on the bridge and temples to achieve minimal storage.

[0005] For example, a Chinese utility model patent discloses a pair of hook-ear glasses (CN221827134U). In this patent, the glasses fold as follows: the two frames are brought together by folding the crossbeam, and the temples are folded and stored between the two frames. Another example is a Chinese utility model patent that discloses a pair of folding glasses with lens protection (CN212341622U). In this patent, the glasses fold as follows: the temples are folded and arranged on both sides of the frame, and the two frames are brought together tightly by folding the crossbeam and are on the same plane.

[0006] Regardless of the folding mechanism, all eyeglasses rely on the rotational connection between their folding components. This rotational connection typically includes shaft supports mounted on the folding components, with a connecting shaft passing through these supports to achieve the rotational connection.

[0007] Currently, most folding components of existing foldable glasses are made of metal and are generally manufactured by casting or stamping. This manufacturing process is relatively expensive and has low processing efficiency. Furthermore, due to the limitations of processing precision, the folding components have a large thickness, which also means that the thickness after folding cannot be reduced. Summary of the Invention

[0008] In order to overcome the shortcomings of the prior art, the present invention provides a folding component for eyeglasses, which has a simple structure, is easy to assemble, can be manufactured conveniently and efficiently, and has a low manufacturing cost.

[0009] The folding component of the eyeglasses of this utility model includes a long strip-shaped main body. At least one end of the main body along its length is provided with a shaft support member. The main body has a flat structure and a uniform lateral width, which is less than its longitudinal height. One end of the main body is provided with an insertion groove that corresponds to and mates with the shaft support member. The insertion groove has openings on at least the two lateral end faces and one end face of the main body. The shaft support member has a long strip-shaped flat structure and a uniform longitudinal height, which is the same as the lateral width of the main body. One end of the shaft support member extends laterally along its length to form an outward protrusion. The outward protrusion is provided with a longitudinally penetrating connecting hole for inserting a connecting shaft, such as for inserting a hinge screw. The other end of the shaft support member has a connecting post that mates with the insertion groove at one end of the main body for insertion and fixation.

[0010] Furthermore, the connecting post has a uniform lateral width, and the lateral width of the connecting post is the same as that of the main body. This allows the lateral sides of the connecting post to be flush with the lateral sides of the main body when the connecting post is inserted into the insertion slot, making the connection structure more compact and aesthetically pleasing.

[0011] In one preferred embodiment, the shaft support is a single component, located at the midpoint of the longitudinal direction of one end face of the main body. The space on the upper and lower sides of the shaft support can be used for the insertion of shaft supports for other folding components of the eyeglasses.

[0012] In another preferred embodiment, at least two shaft supports are arranged longitudinally at intervals, and these shaft supports are aligned, with the space between adjacent shaft supports allowing for the insertion of shaft supports for other folding components of the eyeglasses.

[0013] Furthermore, there is a height difference between the upper end of the uppermost longitudinal shaft support and the upper end of one end of the main body, and between the lower end of the lowermost longitudinal shaft support and the lower end of one end of the main body. For example, the upper end of the uppermost longitudinal shaft support can be higher than the upper end of one end of the main body; alternatively, it can be lower than the upper end of one end of the main body. When it is lower than the upper end of one end of the main body, a space can be formed for the insertion of shaft supports for other folding components. Similarly, the same can be true between the lowermost longitudinal shaft support and the lower end of one end of the main body.

[0014] Alternatively, the upper end of the uppermost shaft support member and the upper end of one end of the main body, as well as the lower end of the lowermost shaft support member and the lower end of one end of the main body, can be flush with each other, which can improve the aesthetics.

[0015] Furthermore, the insertion slot that mates with the uppermost shaft support in the longitudinal direction has a notch at the upper end of one end of the main body; the insertion slot that mates with the lowermost shaft support in the longitudinal direction has a notch at the lower end of one end of the main body. The design of these notches allows portions of the uppermost and lowermost shaft supports to extend upward or downward along the notches, such that the upper end of the uppermost shaft support is higher than the upper end of one end of the main body, and the lower end of the lowermost shaft support is lower than the lower end of one end of the main body. Alternatively, it can allow the uppermost shaft support and the upper end of one end of the main body, as well as the lowermost shaft support and the lower end of one end of the main body, to be flush.

[0016] Furthermore, both the main body and the shaft support are processed from a metal sheet of uniform thickness by laser cutting. The thickness of the metal sheet is the same as the lateral width of the main body and the longitudinal height of the shaft support. Laser cutting is a high-precision processing method that can ensure the accurate shape and size of the processed main body and shaft support, thereby improving assembly accuracy and production efficiency. The main body and shaft support can be precisely arranged on the metal sheet according to their size and shape, maximizing the use of raw materials and further reducing production costs.

[0017] Furthermore, after the connecting column of the shaft support and the insertion groove of the main body are inserted, they are fixed at the joint by laser welding to ensure the reliability of the connection between the shaft support and the main body. Laser welding can also eliminate visible gaps and improve aesthetics.

[0018] Cutting and welding can both use the same type of laser equipment. By simply adjusting the equipment's operating parameters, such as laser power, pulse frequency, and pulse width, it can be used for cutting or welding. For manufacturers, this can further reduce the cost of purchasing equipment.

[0019] Furthermore, the metal sheet is made of stainless steel. Besides its excellent corrosion resistance, strength, toughness, and aesthetics, stainless steel also exhibits good absorption of laser energy and minimal thermal deformation, thus improving the efficiency and quality of laser cutting and welding.

[0020] The folding component of the eyeglasses of this invention can be a component of the eyeglass beam or a component of the temple. The shaft support of the folding component can be used to establish a pivotal connection with the shaft support of other folding components through a connecting shaft.

[0021] The beneficial effects of this utility model are as follows: Since the main body and the shaft support of the folding component of the glasses are both long and flat structures with uniform and identical horizontal width and vertical height, the connection structure of the main body and the shaft support is simple and easy to assemble. This allows the main body and the shaft support of the folding component to be cut and processed from sheets of uniform thickness, which can be manufactured conveniently and efficiently with low manufacturing costs. Furthermore, the final folding component is relatively thin and light, which helps to reduce the thickness after folding when applied to folding glasses. Attached Figure Description

[0035] The structure of the folding component of the eyeglasses in this embodiment of the invention is as follows: Figure 1-9As shown, the main body 1 has a long, flat structure. A shaft support 2 is provided at both ends of the main body 1 along its length. The main body 1 has a uniform lateral width w1, meaning the lateral width is the same at all positions. The lateral width w1 of the main body 1 is less than its longitudinal height h1, resulting in an overall flat shape. Both ends of the main body 1 are provided with insertion grooves 10 that correspond to and mate with the shaft support 2. The insertion grooves 10 have slots 101 on both lateral end faces of the main body 1 and slots 102 on one end face of the main body 1. The insertion grooves 10 have a uniform height h2, meaning the lateral width is the same at all positions. The longitudinal height h2 is the same for all shaft support members 2. The shaft support member 2 is a long strip-shaped flat structure with a uniform longitudinal height h3. That is, the longitudinal height h3 at each position of the shaft support member 2 is the same, and the longitudinal height h3 of the shaft support member 2 is the same as the transverse width w1 of the main body 1. One end of the shaft support member 2 extends laterally along the length direction to form an outward protrusion 21. The outward protrusion 21 is provided with a longitudinal through-hole 210, which can be used to connect shafts, such as the insertion connection of hinge screws 3. The other end of the shaft support member 2 has a connecting post 22 that is inserted and fixed with the insertion groove 10 at one end of the main body 1.

[0036] The connecting post 22 has a uniform lateral width w2, and the lateral width w2 of the connecting post 22 is the same as the lateral width w1 of the main body 1. This makes the lateral sides of the connecting post 22 flush with the lateral sides of the main body 1 when the connecting post 22 is inserted into the insertion slot 10, making its connection structure more compact and aesthetically pleasing.

[0037] In this embodiment, the shaft support 2 is a single component, located at the midpoint of the longitudinal direction of one end face of the main body 1, such as... Figure 4 As shown, the spaces on the upper and lower sides of the shaft support 2 can be used for the insertion of shaft supports for other folding components of the eyeglasses, see reference. Figure 8 , 9 The insertion slot 10 is located at the middle of one end of the main body 1. It has a top surface and a bottom surface distributed longitudinally. The distance between the top surface and the bottom surface of the insertion slot 10, i.e., the longitudinal height h2 of the insertion slot 10, is the same as the longitudinal height h3 of the shaft support member 2. The longitudinal height h3 of the shaft support member 2 is the same as the transverse width w1 of the main body 1. Therefore, the cross-sectional shape of the connecting column 22 and the insertion slot 10 is square.

[0038] Both the main body 1 and the shaft support 2 are laser-cut from a metal sheet of uniform thickness. The thickness of the metal sheet is the same as the lateral width w1 of the main body 1 and the longitudinal height h3 of the shaft support 2. Laser cutting is a high-precision processing method that ensures the accurate shape and size of the processed main body 1 and shaft support 2. It can improve assembly accuracy and production efficiency. The main body 1 and shaft support 2 can be precisely arranged on the metal sheet according to their size and shape, maximizing the use of raw materials and further reducing production costs.

[0039] After cutting out the main body 1 and the shaft support 2 from the metal sheet, the connecting post 22 of the shaft support 2 and the insertion slot 10 of the main body 1 are inserted to achieve initial positioning. Then, the joint between the two is fixed by laser welding to ensure the reliability of the connection between the shaft support 2 and the main body 1.

[0040] Since both cutting and welding processes use laser equipment, the same model of laser equipment can be used. By simply adjusting the equipment's operating parameters, such as laser power, pulse frequency, and pulse width, it can be used for cutting or welding. For manufacturers, this can further reduce equipment purchase costs.

[0041] The metal sheet is made of stainless steel. In addition to its good corrosion resistance, strength, toughness, and aesthetics, stainless steel has a good absorption rate for laser energy and low thermal deformation, which can improve the efficiency and quality of laser cutting and welding.

[0042] In this embodiment, the folding component of the eyeglasses is part of the temples of the eyeglasses, and the temples of the eyeglasses are as follows: Figure 8 , 9 As shown, it includes a front section 41 and a rear section 42. The folding component in this embodiment is the front section 41 of the glasses. As shown in the figure, the front and rear ends of the folding component in this embodiment have shaft support members 2, which can be pivotally connected to the outer end of the frame 43 and the front end of the rear section 42 of the temple through connecting shafts, so as to realize partial and overall folding of the temple.

[0043] In other embodiments, the folding component may also be a component of the eyeglasses' beam, enabling the two frames 43 to fold together.

[0044] Alternatively, in other embodiments, at least two shaft support members 2 may be arranged at intervals along the longitudinal direction, and these shaft support members 2 may be aligned, with the space formed between adjacent shaft support members 2 allowing for the insertion of shaft support members for other folding components of the eyeglasses.

[0045] In such Figure 10 , 11In the second, third, and fourth embodiments shown in Figures 1 and 12, two shaft support members 2 are used, as shown in Figures 1 and 2. Figure 13 In the fifth embodiment shown, three shaft support members 2 are used.

[0046] When the number of shaft support members 2 is at least two, there is a height difference between the upper end of the uppermost shaft support member 2 in the longitudinal direction and the upper end of one end of the main body 1, and between the lower end of the lowermost shaft support member 2 in the longitudinal direction and the lower end of one end of the main body 1.

[0047] like Figure 11 , 13 In the third and fifth embodiments shown, the upper end of the shaft support 2 located at the uppermost point in the longitudinal direction is higher than the upper end of one end of the main body 1, and the lower end of the shaft support 2 located at the lowermost point in the longitudinal direction is lower than the lower end of one end of the main body 1. This design can reduce the requirement for the longitudinal height h1 of the main body 1 and is beneficial to improving the structural strength of the connection.

[0048] like Figure 12 In the fourth embodiment shown, the upper end of the shaft support 2 located at the top in the longitudinal direction is lower than the upper end of one end of the main body 1, and the lower end of the shaft support 2 located at the bottom in the longitudinal direction is higher than the lower end of one end of the main body 1. This allows space to be formed above the uppermost shaft support 2 and below the lowermost shaft support 2 for inserting shaft support members of other folding components, enabling the connection of more shaft support members of other folding components with greater longitudinal height, which is beneficial to improving the connection strength.

[0049] In such Figure 10 In the second embodiment shown, the upper end of the uppermost shaft support 2 in the longitudinal direction is flush with the upper end of one end of the main body 1, and the lower end of the lowermost shaft support 2 in the longitudinal direction is flush with the lower end of one end of the main body 1. This arrangement makes the connection structure more compact, enhances the sense of unity, and improves the visual aesthetics.

[0050] In the second, third, and fifth embodiments described above, the insertion groove 10 that mates with the uppermost shaft support 2 in the longitudinal direction has a slot 103 at the upper end of one end of the main body 1, and the insertion groove 10 that mates with the lowermost shaft support 2 in the longitudinal direction has a slot 103 at the lower end of one end of the main body 1. The design of the slot 103 allows parts of the uppermost and lowermost shaft support 2 to extend upward or downward along the slot 103, and enables them to connect to shaft support 2 with a larger longitudinal height h3. This reduces the requirement for the longitudinal height h1 of the main body 1, and also allows the upper or lower end of the shaft support 2 it accommodates to be flush with the upper or lower end of one end of the main body 2, thereby improving aesthetics.

[0051] In the fourth embodiment described above, none of the insertion slots 10 have a groove 103. Although this leads to an increase in the longitudinal height h1 of the main body 1, the shaft support 2 and the insertion slot 10 have a larger contact surface and welding gap, which makes the connection between the two more secure.

[0052] In other embodiments, the main body 1 may have a shaft support 2 at only one end along its length, and the other end of the main body 1 without the shaft support 2 may be connected and fixed to the inner and outer ends of the frame and the ear hook component of the temple by other means, such as welding, riveting, or plugging.

[0053] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
