[0037] This utility model provides a temple connection structure that solves the problem of traditional screws loosening due to vibration, and provides a smooth and uniform damping feel for opening and closing the temples.

[0038] The following is combined Figures 1-9 The technical solution provided by this utility model will be described in more detail.

[0039] Example 1:

[0040] See Figures 1-9 As shown, the temple connection structure provided by this utility model includes a receiving shaft 1, a plug-in shaft 2, and a rubber pad 3. Specifically, a single hinge 4 is fixed to one of the temple 100 and the frame 200, while a mating groove 6 is provided on the other. The single hinge 4 extends into the mating groove 6 and has a first hole 41. The rubber pad 3 is located on one side or opposite sides of the single hinge 4, and a portion of the rubber pad 3 extends into the first hole 41. The receiving shaft 1 passes through the groove wall of the mating groove 6 and the first hole 41. The plug-in shaft 2 is inserted into the receiving shaft 1, and the two are interference-fitted, thereby rotatably connecting the temple 100 and the frame 200. The rubber pad 3 is clamped between the groove wall of the mating groove 6 and the single hinge 4.

[0041] Among them, see Figure 2 As shown, the mating groove 6 has two opposing sidewalls, and each sidewall has a coaxial second hole 61 for the receiving shaft 1 and the insertion shaft 2 to pass through. The single hinge plate 4 is a flat, sheet-like structure with a through hole, i.e., the first hole 41. During assembly, the single hinge plate 4 can be inserted into the mating groove 6, aligning its first hole 41 with the second holes 61 on the two sidewalls of the mating groove 6.

[0042] As an optional implementation, see Figures 5-8 The receiving shaft 1 is provided with a receiving groove 13, and the insertion shaft 2 includes a mortise 22, which is inserted into the receiving groove 13 and the two are interference fit.

[0043] The interference fit between the receiving shaft 1 and the insertion shaft 2 is key to achieving a secure locking mechanism. During design and manufacturing, the outer diameter of the mortise 22 is precisely machined to be slightly larger than the inner diameter of the receiving groove 13; this dimensional difference is called the "interference fit." When the mortise 22 is forcefully pressed into the receiving groove 13, a tremendous radial pressure is generated between the outer wall of the mortise 22 and the inner wall of the receiving groove 13, resulting in extremely strong friction and clamping force. This combines the receiving shaft 1 and the insertion shaft 2 into a single, inseparable unit, functionally resembling a single solid shaft. Understandably, this connection method relies entirely on the elastic-plastic deformation of the material and the resulting normal pressure. Because it does not involve threads, it effectively avoids the risk of loosening due to vibration.

[0044] As an optional implementation, see Figures 5-7 As shown, the receiving shaft 1 includes a first end head 11 and a receiving post 12 that are fixedly connected. The outer diameter of the first end head 11 is larger than the outer diameter of the receiving post 12. The receiving groove 13 is opened on the receiving post 12. The receiving post 12 passes through the groove wall of the docking groove 6 and the first hole 41. The first end head 11 abuts against an outer side wall of the docking groove 6.

[0045] As an optional implementation, see Figure 5 , Figure 6 and Figure 8 As shown, the insertion shaft 2 also includes a second end head 21. The outer diameter of the second end head 21 is larger than the outer diameter of the mortise 22. The second end head 21 is fixed to one end of the mortise 22 and abuts against the outer wall of the mating groove 6.

[0046] As an optional implementation, see Figure - Figure 8 As shown, the mortise 22 in this embodiment includes an integrally formed wide diameter section 221 and a narrow diameter section 222. The wide diameter section 221 is fixedly connected to the second end head 21. The inner contour of the receiving groove 13 matches the shape of the mortise 22. To further enhance the reliability of the interference fit and prevent the insertion shaft 2 from coming out of the receiving shaft 1 due to axial external force in extreme cases, anti-loosening teeth (not shown) are provided on the outer periphery of the mortise 22 and the inner wall of the receiving groove 13.

[0047] Anti-pull-out teeth can include, but are not limited to, annular grooves, knurled textures, or micro-reverse tooth structures. These can mesh with each other during pressing, significantly increasing axial pull-out resistance and providing double protection for the long-term stability of the connection.

[0048] In the assembled state, see Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the two rubber pads 3 are respectively disposed on opposite sides of the single hinge plate 4. That is, one rubber pad 3 is clamped between one side of the single hinge plate 4 and one inner wall of the mating groove 6, and the other rubber pad 3 is clamped between the other side of the single hinge plate 4 and the other inner wall of the mating groove 6.

[0049] The presence of the rubber pad provides several beneficial technical effects. First, it effectively fills the minute gaps that may exist between the single hinge 4 and the inner wall of the mating groove 6 due to manufacturing tolerances, ensuring that the temple 100 does not wobble or make abnormal noises, thereby improving wearing stability. Second, the pre-tightening force generated by the rubber pad 3 under pressure provides a smooth, uniform, and comfortable damping feel for the opening and closing rotation of the temple 100, avoiding the stiffness that may be caused by direct friction between metals.

[0050] Preferably, the rubber pad is a PEK high-temperature rubber pad, which has excellent high-temperature resistance and can work for a long time at 260℃-300℃, and can withstand even higher temperatures (such as above 350℃) for short periods; it also has excellent thermal stability, high mechanical property retention at high temperatures, is not easy to soften or deform, is easy to manufacture, and prevents deformation during the manufacturing process. Tests have shown that using this PEK high-temperature rubber pad, the temples can still maintain smooth operation after tens of thousands of opening and closing cycles.

[0051] As an optional implementation, see Figure 9 As shown, the rubber gasket 3 includes an integrally formed washer portion 31 and a collar portion 32, wherein: see Figure 5 and Figure 6 As shown, the collar portion 32 extends into the first hole 41, the receiving shaft 1 passes through the collar portion 32 and the washer portion 31, and the washer portion 31 is clamped between the groove wall of the mating groove 6 and the single hinge piece 4.

[0052] With this integrated rubber gasket 3 structure, during assembly, the operator only needs to insert the collar portion 32 of the integrated rubber gasket 3 into the first hole 41 of the single hinge plate 4. Due to the presence of the collar portion 32, the rubber gasket 3 can automatically and accurately position itself around the first hole 41, and its gasket portion 31 flatly adheres to one side of the single hinge plate 4. Subsequently, this single hinge plate 4 assembly with the pre-installed rubber gasket 3 is placed into the mating groove 6, and then the receiving shaft 1 and the insertion shaft 2 are inserted in sequence to complete the assembly. This significantly improves assembly efficiency and reduces the risk of failure due to gasket displacement during assembly.

[0053] The collar portion 32, extending into the first hole 41, forms an elastic bushing between the outer wall of the receiving shaft 1 and the inner wall of the first hole 41 after the receiving shaft 1 passes through. When the temple 100 rotates, rotational friction mainly occurs between the outer wall of the receiving shaft 1 and the inner wall of the collar portion 32. Since the collar portion 32 is usually made of a material with self-lubricating or wear-resistant properties superior to metal, this bushing effectively prevents direct wear between the metal pin and the metal hinge hole, further extending the service life of the entire hinge structure. At the same time, the washer portion 31 remains reliably clamped between the side of the single hinge piece 4 and the inner wall of the mating groove 6, continuing to perform its core functions of filling the gap, providing rotational damping, and buffering.

[0054] In this embodiment, the rubber pad 3 is made of PEK material.

[0055] As an optional implementation, see Figure 5 and Figure 6 As shown, there are two rubber pads 3, which are located on opposite sides of the single hinge piece 4.

[0056] As an optional implementation, see Figure 1 and Figure 4 As shown, an arc-shaped limiting part 5 is fixed to the connecting end of the temple 100. The concave side of the arc-shaped limiting part 5 faces the inner side of the temple 100. The single hinge piece 4 has a circular structure and is fixed to the concave side of the arc-shaped limiting part 5. The arc-shaped limiting part 5 is a structure formed by integrally bending the temple 100.

[0057] The connecting end of the temple 100 is integrally bent into a C-shaped arc-shaped limiting part 5 by processes such as stamping and bending from the body material of the temple 100 (e.g., titanium alloy, stainless steel, or high-strength sheet metal). The concave side of this arc-shaped limiting part 523b faces the inner side of the temple 100, forming a stable mounting base with precise curvature. During manufacturing, the annular single hinge piece 4 is placed inside the concave side of the arc-shaped limiting part 5 and then permanently fixed by a high-strength connection method, such as using laser welding or brazing to form a metallurgical bond, or using high-strength structural adhesive for bonding.

[0058] The assembly process of this embodiment is described below. During assembly, a rubber pad 3 is placed on one side of the single hinge 4, and then the connecting end of the temple 100, along with the rubber pad 3, is placed into the mating groove 6 of the frame 200. Then, another rubber pad 3 is placed in the gap between the other side of the single hinge 4 and the inner wall of the mating groove 6, and the position of the temple 100 is adjusted to ensure that the second holes 61 on both sides of the mating groove 6, the center holes of the two rubber pads 3, and the first hole 41 of the single hinge 4 are precisely coaxially aligned. Subsequently, the receiving shaft 1 is inserted from one side of the mating groove 6, passing through the second shaft hole on that side, the first rubber pad 3, the first hole 41 of the single hinge 4, the second rubber pad 3, and the second shaft hole on the other side of the mating groove 6 in sequence. At this time, the first end head 11 of the receiving shaft 1 will abut against the outer wall of one side of the mating groove 6, playing a preliminary positioning and limiting role. Finally, align the mortise 22 of the insert shaft 2 with the open end of the receiving groove 13 of the receiving shaft 1, and apply stable axial pressure using a special pressing tool to force the mortise 22 into the receiving groove 13 until the second end head 21 of the insert shaft 2 is completely against the outer wall of the other side of the mating groove 6, thereby forming a firm interference fit between the mortise 22 and the receiving groove 13.

[0059] After assembly, see Figures 3-6 As shown, the receiving shaft 1 and the insertion shaft 2 are tightly joined into a whole through an internal interference fit. The first end head 11 and the second end head 21 respectively lock onto the two side walls of the mating groove 6 from the outside, providing reliable axial restraint to prevent the pin assembly from axially shifting. Furthermore, due to the compression of the mortise 22, the hollow receiving shaft 1 will generate a slight radial expansion, causing its outer wall to press tightly against the inner wall of the two rubber pads 3 and the hole wall of the first hole 41 of the single hinge 4 with greater pressure, forming an additional radial locking force. This dual locking mechanism, combining "internal interference locking" and "external radial expansion," ensures that the entire hinge connection has long-term high stability, and the connection is not easy to loosen even if the user frequently opens and closes the temple 100 or wears it in a vibrating environment.
