[0026] To make the above-mentioned purposes, features, and advantages of the present invention more clearly understood, the following provides a clear and complete description of the specific embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the specific details described below are only a portion of the embodiments of the present invention, and the present invention can also be implemented in many other embodiments different from those described herein. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figures 1 to 3In one embodiment, a multi-positioning point hinge device 100 includes: a head 1, a temple 2, and a pin 3. The head 1 includes a circular mating portion 11, which is provided with a slot 12 extending from the outside to the inside in the horizontal direction, and a positioning slot 13 extending vertically (i.e., the thickness direction of the head 1). The positioning slot 13 is provided with a plurality of positioning angles 14 spaced apart along the circumferential direction. At least two elastic legs 21 are provided at intervals at the front end of the temple 2, and mounting holes 22 are provided vertically at the ends of the elastic legs 21. The elastic legs 21 can extend from the slot 12 into the mating portion 11. The number of pins 3 corresponds to the number of elastic legs 21. The pins 3 are inserted into the mounting holes 22 with an interference fit. Under the elastic force of the elastic legs 21, the pins 3 abut against the positioning angles 14.

[0030] In this multi-position hinge device 100, an elastic leg 21 on the temple 2 is inserted through a slot 12 into the head 1. The elastic leg 21 exerts outward elastic tension, and a pin 3 is secured within a mounting hole 22 of the elastic leg 21. The pin 3 directly abuts against a locating angle 14 of the locating slot 13 to maintain its position. To adjust the angle of the temple 2, the temple 2 is rotated by an external force, and the elastic leg 21 drives the pin 3, causing it to slide along the wall of the locating slot 13 until it abuts against another adjacent locating angle 14. This hinge device eliminates the need for threaded mounting or solder joints; the angle of the temple 2 can be adjusted directly through multi-point abutment and rotation.

[0031] The elastic legs 21 may be spaced apart in the longitudinal direction (ie, the width direction of the glasses leg 2 ), or may be spaced apart in both the longitudinal direction and the vertical direction.

[0032] In one embodiment of the elastic legs 21, there are two elastic legs 21 and four positioning angles 14. The positioning angles 14 are grouped together in pairs, and the positioning angles 14 in each group can be arranged opposite each other. In one embodiment, the line connecting one group of positioning angles 14 is perpendicular to the line connecting the other group of positioning angles 14. This allows the pins 3 on the elastic legs 21 to first abut against one group of positioning angles 14. Then, after the elastic legs 21 are rotated, the pins 3 on the elastic legs 21 slide until they abut against the other group of positioning angles 14. This ensures that the temple 2 rotates exactly 90 degrees relative to the head 1, allowing the temple 2 to be unfolded and folded.

[0033] In another embodiment, the elastic leg 21 includes a first leg 211 and a second leg 212. The positioning slot 13 is shaped like a square, and its four corners are respectively the first corner, the second corner, the third corner, and the fourth corner. Each corner is a positioning corner 14. The first corner is opposite to the third corner, and the second corner is opposite to the fourth corner. Figure 3 When the glasses leg 2 is in the unfolded state, the pin 3 on the first leg 211 abuts against the first horn, and the pin 3 on the second leg 212 abuts against the third horn; please refer to Figure 4When the glasses leg 2 is rotated and switched to the folded state, the pin 3 on the first leg 211 slides along the groove wall of the positioning groove 13 until it abuts the second corner body, and the pin 3 on the second leg 212 slides along the groove wall of the positioning groove 13 until it abuts the fourth corner body.

[0034] See also Figure 1 To prevent the elastic leg 21 from over-rotating, a first flange 15 is provided between the first and fourth corners, and a second flange 16 is provided between the second and third corners, giving the positioning slot 13 a shape similar to the Chinese character "I." The first and second flanges 15, 16 abut against the pin 3, preventing the elastic leg 21 from rotating further when it is extended or folded.

[0035] In another embodiment, the spacing between the elastic legs 21 gradually increases from one end connected to the temple 2 to the other end, which can increase the elastic tension of the elastic legs 21 and make the contact and positioning between the pin 3 and the positioning angle 14 more stable.

[0036] The pin 3 is cylindrical, with a diameter slightly larger at its center than at its top and bottom ends, with the diameter difference ranging from 0.05mm to 0.1mm. The pin 3 has an interference fit with the elastic leg 21. The pin 3 can be made of phosphor bronze, and the temple 2 can be made of titanium alloy.

[0037] See also Figure 5 The present invention also discloses a pair of glasses 200, comprising a frame 4 and two sets of the multi-positioning-point hinge devices 100 as described above, with two hinges 1 fixedly connected to the two sides of the frame 4. The temples 2 of the glasses 200 have a simple structure and are smooth and stable to unfold and fold.
