DETAILED DESCRIPTION

[0041] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0043] The following describes the glasses shaft structure in detail through a specific embodiment:

[0044] like Figures 1 to 6As shown, the eyeglass shaft structure provided by the present invention includes a fixing frame 7, a first connecting bracket 2, a fixing assembly 1 and a first elastic member 3. The fixing frame 7 is fixedly connected to the frame to support the eyeglass shaft structure. The first connecting bracket 2 is connected to the fixing frame 7 through the fixing assembly 1. Specifically, the fixing assembly 1 includes a fixing rod 11 and a locking member 12. The fixing rod 11 passes through the fixing frame 7 and the first connecting bracket 2 and is locked and fixed by the locking member 12. In addition, as shown in FIG. Figure 5 As shown, the first connecting bracket 2 includes a rotating portion 21, a mounting portion 22, and a first bracket connecting rod 23. The rotating portion 21 and the mounting portion 22 are fixedly connected by the first bracket connecting rod 23. Furthermore, a protrusion 211 is formed on the rotating portion 21 and extends radially along the rotating portion 21. Therefore, one end of the first elastic member 3 is connected to the frame, and the other end can abut against the protrusion 211. In other words, when the temples of the eyeglasses are in the unfolded state, one end of the first elastic member 3 can abut against the protrusion 211 of the first connecting bracket 2. Since the elastic force of the elastic member can drive the rotating portion 21 to rotate in the opposite direction, i.e., the direction in which the temples fold, the temples can be retracted in the folding direction, thereby providing a force that clamps the head when the user wears the eyeglasses, preventing the eyeglasses from falling off.

[0045] The connection between the fixing frame 7 and the frame can be a bolt connection or a clamping connection, and a mounting hole for the fixing rod 11 to pass through can be provided inside the fixing frame 7. Furthermore, countersunk holes can be provided at both ends of the fixing frame 7, and the locking member 12 can abut against the surface of the countersunk hole after being locked to fix the fixing rod 11 relative to the fixing frame 7. The fixing rod 11 can be a hexagonal bolt or a plain rod with a threaded end. When the fixing rod 11 is a hexagonal bolt, the locking member 12 can be a nut. When the fixing rod 11 is a plain rod with a threaded end, the locking member 12 can be two nuts. Of course, the fixing rod 11 and the locking member 12 can also be other structures with a locking function, as long as the rotating part 21 can be locked with the fixing frame 7. Furthermore, a mounting hole matching the fixing rod 11 can be provided on the rotating part 21 so that the first connecting bracket 2 can rotate relative to the fixing rod 11.

[0046] The mounting portion 22 of the first connecting bracket 2 can be secured to the temple via bolts. A groove 51 matching the mounting portion 22 can be provided on the temple to facilitate positioning of the first connecting bracket 2. The first bracket connecting rod 23 can be integrally formed with the mounting portion 22 and the rotating portion 21. The first bracket connecting rod 23 can also be connected to the protrusion 211, so that rotation of the protrusion 211 can drive the temple to expand or contract, reducing rotational resistance.

[0047] like Figure 6As shown, the first elastic member 3 can be a spring, one end of which can be welded to the frame. It is understood that the first elastic member 3 extends in the direction of the temples. Therefore, when the glasses are in the retracted state, the protrusion 211 is away from the first elastic member 3, that is, the first elastic member 3 does not contact the protrusion 211. At this time, the temples are in the folded state, that is, Figure 1 and Figure 4 When the user wants to wear the glasses, the temples are in the unfolded state. Figure 2 and Figure 3 As the temples unfold from their retracted state, the rotating portion 21 rotates around the fixing rod 11. The protrusion 211 gradually contacts and tightens against the end of the first elastic member 3 near the fixing frame 7 until the temples are fully extended. At this point, the first elastic member 3 is in a compressed state. The rebound force of the first elastic member 3 drives the protrusion 211 in the opposite direction, toward the temples' retraction. This provides a clamping force on the wearer's head, ensuring a more secure fit.

[0048] The eyeglass shaft structure provided by the present invention includes a fixing frame 7, a first connecting frame 2, a fixing assembly 1 and a first elastic member 3. The fixing frame 7 is fixedly connected to the frame to support the entire device. The first elastic member 3 can abut against the protrusion 211 of the first connecting frame 2 and thus have a tendency to push the rotating top of the first connecting frame 2 to rotate. The fixing assembly 1 can fix the fixing frame 7 and the rotating portion 21 of the first connecting frame 2, and at the same time, the rotating portion 21 of the first connecting frame 2 can rotate relative to the fixing frame 7. Therefore, when the user wears the glasses, the glasses are in an open state, the first elastic member 3 can abut against the protrusion 211 and make the rotating portion 21 have a tendency to rotate in the folding direction, so that the mounting portion 22 and the temples can be driven to contract in the folding direction, thereby enabling the user to have a force to clamp the head when wearing the glasses, thereby preventing the glasses from falling off when worn.

[0049] like Figures 7 to 9 As shown, the eyeglass shaft structure provided by the utility model also includes a first cam 4, a second cam 5 and a second elastic member 6. The end of the first cam 4 close to the rotating part 21 is fixedly connected to the rotating part 21, and the first cam 4 can rotate relative to the fixed rod 11. Therefore, when the rotating part 21 rotates relative to the fixed rod 11, the first cam 4 can be driven to rotate together. The second cam 5 is arranged on the side of the first cam 4 away from the rotating part 21 and can slide along the axial direction of the fixed rod 11. The second elastic member 6 is arranged on the side of the second cam 5 away from the first cam 4 and can elastically expand and contract along the axial direction of the fixed rod 11. At the same time, the second elastic member 6 is fixedly connected to the second cam 5 at one end close to the second cam 5, and the other end is fixedly connected to the locking member 12, so that the second cam 5 and the second elastic member 6 can only move along the axial direction of the fixed rod 11.

[0050] Furthermore, a protrusion 41 is provided on the side of the first cam 4 that is adjacent to the second cam 5, and a groove 51 that matches the protrusion 41 is provided on the side of the second cam 5 that is adjacent to the first cam 4. In other words, the first cam 4 and the second cam 5 are connected by a snap fit via the protrusion 41 and the groove 51. Alternatively, the groove 51 can be provided on the first cam 4 and the protrusion 41 on the second cam 5, depending on actual needs.

[0051] Therefore, when the temple is in the retracted state, the projection 41 is embedded in the groove 51, leaving the second elastic member 6 free. When the temple is unfolded from the retracted state, the rotating portion 21 rotates the first cam 4. Since the second cam 5 and the second elastic member 6 can only move axially along the fixed rod 11, the first cam 4 can rotate relative to the second cam 5, causing the projection 41 to move out of the groove 51 and abut against the flat surface of the second cam 5. This pushes the second cam 5 toward the second elastic member 6 and compresses it. This creates a damping force during the unfolding of the temple, providing a certain tactile feel when unfolding or retracting the glasses, enhancing the user experience.

[0052] The first cam 4 can be welded to the rotating portion 21, or a rod and slot can be provided on the side of the first cam 4 adjacent to the rotating portion 21 to allow the first cam 4 to be inserted and connected to the rotating portion 21. Alternatively, a special-shaped groove 212 can be provided on the end of the rotating portion 21 near the first cam 4, and a special-shaped block 42 can be provided on the end of the first cam 4 near the rotating portion 21, with the special-shaped block 42 being retained in the special-shaped groove 212. The special-shaped block 42 can be rectangular, and the special-shaped block 42 can be integrally formed with the first cam 4. The second cam 5 can be welded to the second elastic member 6, which can be welded to the locking member 12. The groove 51 can be shaped like an arc extending along the circumference of the second cam 5. Similarly, the protrusion 41 can be shaped like an arc that matches the shape of the groove 51. To facilitate positioning, multiple protrusions 41 can be provided on the first cam 4, spaced apart, and the specific configuration can be determined based on actual needs. It is understandable that the plurality of protrusions 41 are arranged in a one-to-one correspondence with the plurality of grooves 51, and the shapes and sizes of the plurality of protrusions 41 can be different, and can be arranged according to actual needs. The second elastic member 6 can be a disc spring.

[0053] like Figure 10 and Figure 11As shown, in some other embodiments, a limiting groove 71 can be provided within the fixing frame 7, extending along the inner circumference of the fixing frame 7. A limiting block 52 is provided on the outer circumference of the second cam 5, which engages in the limiting groove 71, thereby limiting the second cam 5 to move only axially relative to the fixing rod 11. It will be appreciated that the fixing frame 7 has a space for accommodating the first and second cams 5. Multiple limiting grooves 71 can be provided within the fixing frame 7 to further enhance the limiting effect.

[0054] In some embodiments, a first guide hole 72 is defined on a side of the fixing frame 7 near the first elastic member 3. The end of the first elastic member 3 near the protrusion 211 can pass through the first guide hole 72 and abut against the protrusion 211. It will be appreciated that there is a space within the fixing frame 7 to accommodate the protrusion 211. Thus, the first elastic member 3 can extend and retract through the first guide hole 72, ensuring precise positioning and preventing the temple from failing to abut against the protrusion 211 and thus providing a lack of clamping force.

[0055] like Figures 12 to 14 As shown, the present invention further includes a second connecting bracket 8, which is fixedly connected to the frame. The second connecting bracket 8 is provided with a chamber and a second guide hole 81 communicating with the chamber. Therefore, the first elastic member 3 can be accommodated in the chamber and abut against the protrusion 211 through the second guide hole 81 and the first guide hole 72. Furthermore, the first elastic member 3 includes a spring 31 and a connecting shaft 32. One end of the spring 31 can abut against the inner wall of the chamber, and the other end is fixedly connected to the connecting shaft 32. The end of the connecting shaft 32 away from the spring 31 can abut against the protrusion 211 through the second guide hole 81 and the first guide hole 72 in sequence.

[0056] The second connecting bracket 8 can be connected to the frame via bolts or welding. The second guide hole 81 can be identical in size and shape to the first guide hole 72, and the second guide hole 81 and the first guide hole 72 can be co-planar. The spring 31 can be welded to the inner wall of the second connecting bracket 8, and the other end can also be welded to the connecting shaft 32. It will be understood that the size and shape of the connecting shaft 32 match the first guide hole 72 and the second guide hole 81, so that it can pass through the first guide hole 72 and the second guide hole 81 and abut the protrusion 211.

[0057] The present invention also provides a pair of glasses, including the above-described glasses shaft structure, wherein the fixing frame 7 and the mounting portion 22 of the glasses shaft structure are respectively used to connect to the frame and the temples. The glasses can be ordinary glasses or VR glasses or AR glasses, etc. having a shaft structure.
