DETAILED DESCRIPTION

[0036] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0037] Reference Figure 1-Figure 3 This embodiment provides a hinge structure of glasses, which mainly includes three parts: a hinge seat 3, a first hinge arm 1 and a second hinge arm 2. The first hinge arm 1 has a first connection hole 123 for connecting with the temple, and the second hinge arm 2 has a second connection hole for connecting with the frame.

[0038] The first hinge arm 1 includes a first arm body 12, a first connecting member and a first elastic member 13. Among them, one end of the first arm body 12 is connected to the hinge seat 3, and can be specifically integrally formed. A first slot 121 is provided at one end of the first arm body 12 along the length direction, and the first connecting member is movably inserted in the first slot 121, and a first connecting portion 11 is provided at one end facing the outside of the first slot 121; at the same time, the hinge seat 3 has a slide groove 31 connected to the first slot 121, and the first connecting portion 11 is slidably matched with the slide groove 31, so that the first connecting member including the first connecting portion 11 can only move along the length direction of the slide groove 31.

[0039] More specifically, refer to Figure 4-5The first connecting member includes a first rod body 16 and a collar 14. The first connecting portion 11 is integrally formed at one end of the first rod body 16, and the connection between the two forms a first limiting portion 124. The other end of the first rod body 16 is provided with a second limiting portion 125. The collar 14 is slidably sleeved on the first rod body 16. The first elastic member 13 is a spring and sleeved on the first rod body 16. The two ends of the first elastic member 13 are respectively in contact with the first limiting portion 124 and the second limiting portion 125. At the same time, a first plug hole 122 connected to the first slot 121 is provided on the first arm body 12. A first latch 15 is fixedly inserted in the first plug hole 122. The first latch 15 extends into the first slot 121 and abuts against the collar 14 to limit the collar 14 from moving out of the first slot 121. By setting the above structure, when the first connecting member moves out of the first slot 121 under the action of external force, the ring 14 is blocked by the first pin 15, which in turn compresses the first elastic member 13, so that the first elastic member 13 exerts resistance on the first connecting member.

[0040] Reference Figure 5 , Figure 7 The second hinge arm 2 includes a second arm body 22, a second connecting member 23 and a second elastic member 24. A second slot 221 is provided at one end of the second arm body 22 along the length direction; the second connecting member 23 is movably inserted in the second slot 221, and a second connecting portion 21 is provided at one end facing outside the second slot 221.

[0041] The second connection part 21 is movably connected to the first connection part 11. Figure 5 As shown, a buckle structure is used for connection, that is, the first connection part 11 is hook-shaped, and the second connection part 21 is ring-shaped. When installing, the second connection part 21 is inserted into the hook part of the first connection part 11 (the hook part is in an open state at this time), and then the hook part is pressed into a closed state with a tool or device. This connection method allows the second hinge arm 2 to swing up and down or left and right relative to the first connection member (i.e., the first hinge arm 1).

[0042] The second elastic member 24 is a spring; at the same time, a receiving groove 231 is provided through the second connecting member 23, the second elastic member 24 is located in the receiving groove 231 and the two ends thereof are respectively abutted against the two ends of the receiving groove 231; a third slot 232 is provided at one end of the receiving groove 231, a second plug hole 222 is provided on the second arm 22, and a second latch 25 is fixedly inserted in the plug hole; the second latch 25 extends into the third slot 232 and abuts against the second elastic member 24, and is used to limit the second elastic member 24 from moving out of the second slot 221. By setting the above structure, when the second connecting member 23 is moved out of the second slot 221 by an external force, the second elastic member 24 is blocked by the second latch 25, and the second elastic member 24 is compressed, so that the second elastic member 24 exerts resistance on the second connecting member 23.

[0043] Reference Figure 5-6 The hinge seat 3 also has an upper bearing surface 33, a lower bearing surface 32, a left bearing surface 34, a right bearing surface 35 and an auxiliary bearing surface 36. Correspondingly, the end of the second arm body 22 is provided with an upper abutting portion 261, a lower abutting portion 262, a left abutting portion 264, a right abutting portion 263 and an abutting end surface 265; when the second hinge arm 2 swings upward or downward relative to the first connecting member, the upper abutting portion 261 is combined with the upper bearing surface 33 or the lower abutting portion 262 is combined with the lower abutting portion 262 to serve as a force fulcrum for the second hinge arm 2 to apply force to the first connecting member, thereby pulling the first connecting member out of the first slot 121.

[0044] In addition, the left bearing surface 34 and the abutting end surface 265 constitute a first supporting structure for supporting the second hinge arm 2 when the second hinge arm 2 swings to the left relative to the first connecting member to a first preset angle (folded state), and at this time, the abutting end surface 265 presses on the left bearing surface 34, so that the second hinge arm 2 can be maintained at the first preset angle with the first hinge arm 1. The right bearing surface 35 and the abutting end surface 265 constitute a second supporting structure for supporting the second hinge arm 2 when the second hinge arm 2 swings to the right relative to the first connecting member to a second preset angle (extended state), and at this time, the abutting end surface 265 presses on the right bearing surface 35, so that the second hinge arm 2 can be maintained at the second preset angle with the first hinge arm 1.

[0045] In addition, when the second hinge arm 2 continues to swing to the left from the first preset angle or continues to swing to the right from the second preset angle relative to the first connecting member, the left abutment portion 264 is combined with the left bearing surface 34 (the left abutment portion 264 is pressed on the left abutment surface) or the right abutment portion 263 is combined with the auxiliary bearing surface 36 (the right abutment portion 263 is pressed on the auxiliary bearing surface 36) to serve as a fulcrum for the second hinge arm 2 to apply force to the first connecting member, thereby pulling the first connecting member out of the first slot 121.

[0046] The structural principle of this embodiment is:

[0047] In the natural state, due to the presence of the first elastic member 13, the abutting end face 265 of the second arm body 22 is always pressed against the left bearing surface 34 or the right bearing surface 35, depending on whether the hinge structure is in an extended state or a folded state. When the hinge structure is subjected to a longitudinal impact force, the second hinge arm 2 can swing upward or downward to a certain extent relative to the first hinge arm 1 according to the force conditions, and buffer the impact force received by compressing the first elastic member 13, and then can be reset under the action of the first elastic member 13. The second arm body 22 is provided with an upper clearance groove 271 near the upper abutment portion 261, and a lower clearance groove 272 near the lower abutment portion 262; wherein, the upper clearance groove 271 is used to make way for the edge of the upper bearing surface 33, so that the second hinge arm 2 can swing upward to a greater extent, and the function of the lower clearance groove 272 is the same.

[0048] When the second hinge arm 2 is in an extended state or a folded state, if it is subjected to a lateral impact force, the second hinge arm 2 can swing to the left or right by a certain amplitude relative to the first hinge arm 1 according to the force conditions, and cushion the impact force by compressing the first elastic member 13, and then be able to reset under the action of the first elastic member 13.

[0049] In addition, when the second hinge arm 2 swings, it will be subjected to the reverse pulling force generated by the compression of the first elastic member 13. The pulling force is transmitted to the second elastic member 24 and compresses the second elastic member 24, so that the reverse pulling force is buffered; compared with the connection method in which the second connecting part 21 is directly integrally formed with the second arm body 22, the connection reliability between the second connecting part 21 and the second arm body 22 can be increased.

[0050] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
