Abstract
Description
Technical Field
[0001] This utility model relates to the field of eyewear technology, and in particular to a hinge module for AI glasses. Background Technology
[0002] The hinge is a crucial component of eyeglasses. There are generally two types of hinges: non-elastic and elastic. Non-elastic hinges offer high freedom of movement but have a limited fit, resulting in an unstable fit and a tendency to fall off. Elastic hinges typically use torsion springs. Torsion springs have a large inward restoring force, which is generally continuous, leading to discomfort and fatigue. With repeated use, the spring's elasticity weakens, causing instability. Utility Model Content
[0003] In view of the above situation, it is necessary to propose a hinge module for AI glasses that are easy and comfortable to wear.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a hinge module for AI glasses, comprising:
[0005] A fixed base, one end of which extends into a limiting body. A pair of limiting blocks are symmetrically arranged on one side of the limiting body. Each limiting block includes, in sequence, an elastic adjustment limiting surface, an elastic adjustment slope, a limiting valley, and a folding slope extending toward the other limiting block. The heights of the elastic adjustment slope and the folding slope gradually decrease in the direction away from the elastic adjustment limiting surface.
[0006] A movable seat, one end of which is provided with a mounting cylinder, and the limiting body extends into the mounting cylinder;
[0007] A central shaft passes through the mounting cylinder and the limiting body;
[0008] A sliding body is slidably sleeved on the central shaft, and a pair of sliding protrusions are symmetrically arranged on one side of the sliding body;
[0009] An elastic element is sleeved on the central shaft and abuts against the sliding body, giving the sliding body a restoring force close to the limiting body. The movable seat drives the sliding body to rotate, allowing the sliding protrusion to selectively abut against the elastic adjustment limiting surface, the elastic adjustment slope, the limiting valley, or the folding slope.
[0010] Furthermore, the fixed base extends with a stop, the outer diameter of the sliding body is larger than the outer diameter of the limiting body, and the stop is provided with an arc groove that matches the outer diameter of the limiting body.
[0011] Furthermore, the mounting cylinder is provided with a clearance notch that is adapted to the stop block.
[0012] Furthermore, a retaining ring is provided at the end of the central shaft away from the limiting body, and the retaining ring is locked onto the central shaft.
[0013] Furthermore, it also includes a decorative cover, which covers the limiting body and the mounting cylinder, and is fixedly connected to the movable seat.
[0014] Furthermore, the inclination angle of the elastically adjustable slope is 30°-50°, and the inclination angle of the folding slope is 10°-35°.
[0015] Furthermore, the length of the folded slope is greater than the length of the elastically adjustable slope.
[0016] Furthermore, the tilt angle of the elastic adjustment limiting surface is 70°-90°.
[0017] Furthermore, the length of the elastic adjustment slope is greater than the length of the elastic adjustment limiting surface.
[0018] Furthermore, the side of the limiting block facing away from the elastic adjustment slope is an inclined surface, one side of the sliding protrusion is adapted to the inclined surface, and the other side is adapted to the elastic adjustment limiting surface.
[0019] The beneficial effects of this utility model are as follows: The limiting body has two symmetrically arranged limiting blocks, each of which has sequentially extending elastic adjustment limiting surfaces, elastic adjustment slopes, limiting valleys, and folding slopes. The sliding body approaches the limiting body under the push of the elastic element. When the movable seat rotates, it drives the sliding body to rotate. When the sliding protrusion of the sliding body is positioned on the side elastic adjustment limiting surface, it forms a blockage. When the sliding protrusion is located on the elastic adjustment slope, it tends to slide towards the limiting valley. At this time, the two temples of the glasses also tend to move inward, making the wearing stable. When the sliding protrusion is located within the limiting valley, the two are positioned and cooperate. When the sliding protrusion is located on the folding slope, it continues to slide downward to the bottom of the folding slope. The elastic element does not directly provide inward restoring force, but relies on the cooperation between the limiting body and the sliding body, which can improve the service life. Furthermore, the clamping force of the temples is appropriate, making wearing comfortable. When the temples expand outward, they automatically rebound to form a clamping force; when the temples fold inward, they automatically retract, making them convenient to use.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the hinge module of an AI glasses according to this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.
[0035] Please refer to Figures 1-10A hinge module for AI glasses, comprising:
[0036] The fixed base 100 has a limiting body 110 extending from one end. A pair of limiting blocks 111 are symmetrically arranged on one side of the limiting body 110. Each limiting block 111 includes an elastically adjustable limiting surface 112, an elastically adjustable slope 113, a limiting valley 114, and a folding slope 115 extending to the other limiting block 111. The heights of the elastically adjustable slope 113 and the folding slope 115 gradually decrease in the direction away from the elastically adjustable limiting surface 112.
[0037] The movable seat 200 has an installation cylinder 210 at one end, and the limiting body 110 extends into the installation cylinder 210.
[0038] The central shaft 300 passes through the mounting cylinder 210 and the limiting body 110;
[0039] The sliding body 400 is slidably sleeved on the central shaft 300, and a pair of sliding protrusions 410 are symmetrically arranged on one side of the sliding body 400;
[0040] The elastic element 500 is sleeved on the central shaft 300 and abuts against the sliding body 400, giving the sliding body 400 a restoring force close to the limiting body 110. The movable seat 200 drives the sliding body 400 to rotate, so that the sliding protrusion 410 can selectively abut against the elastic adjustment limiting surface 112, the elastic adjustment slope 113, the limiting valley 114, or the folding slope 115.
[0041] The limiting body 110 has two symmetrically arranged limiting blocks 111. Each limiting block 111 has an elastic adjustment limiting surface 112, an elastic adjustment slope 113, a limiting valley 114, and a folding slope 115 extending sequentially. The sliding body 400 approaches the limiting body 110 under the push of the elastic element 500. When the movable seat 200 rotates, it drives the sliding body 400 to rotate. When the sliding protrusion 410 of the sliding body 400 is positioned on the side elastic adjustment limiting surface 112, it will form a blockage. When the sliding protrusion 410 is located on the elastic adjustment slope 113, the sliding protrusion 410 tends to slide towards the limiting valley 114. At this time, the two temples of the glasses also tend to move inward, making the wearing stable. When the sliding protrusion 410 is located in the limiting valley 114, the two are positioned and matched. When the sliding protrusion 410 is located on the folding slope 115, the sliding protrusion 410 will continue to slide down to the bottom of the folding slope 115. The elastic element 500 does not directly provide inward restoring force, but relies on the cooperation of the limiting body 110 and the sliding body 400 to improve service life. The clamping force of the temple is appropriate, making it comfortable to wear. When the temple expands outward, it will automatically rebound to form a clamping force, and when the temple folds inward, it will automatically retract, making it convenient to use.
[0042] Please refer to Figure 3The fixed base 100 extends with a stop 120. The outer diameter of the sliding body 400 is larger than the outer diameter of the limiting body 110. The stop 120 is provided with an arc groove that matches the outer diameter of the limiting body 110. That is, when the sliding body 400 rotates to a certain position, it will be blocked by the stop 120. Preferably, the stop 120 fits against the side of the limiting body 110 facing the mounting cylinder 210.
[0043] Please refer to Figure 2 The mounting cylinder 210 is provided with a clearance notch 211 that matches the stop block 120. This prevents the stop block 120 from blocking the mounting cylinder 210 and ensures the normal rotation of the mounting cylinder 210.
[0044] Please refer to Figure 2 and Figure 3 A retaining ring 600 is provided at one end of the central shaft 300 away from the limiting body 110, and the retaining ring 600 is locked onto the central shaft 300. It can be understood that one end of the central shaft 300 is provided with a convex cap, which abuts against the limiting body 110 from the outside, and the other end is connected to the retaining ring 600. One end of the elastic member 500 abuts against the retaining ring 600 and the other end abuts against the sliding body 400; and / or, one end of the mounting cylinder 210 is open and the other end is provided with an end plate. The center of the end plate is provided with a hole for the central shaft 300 to pass through. The part of the central shaft 300 passing through the end plate is connected to the retaining ring 600. One end of the elastic member 500 abuts against the end plate and the other end abuts against the sliding body 400.
[0045] Please refer to Figure 1 and Figure 3 It also includes a decorative cover 700, which covers the limiting body 110 and the mounting cylinder 210, and is fixedly connected to the movable seat 200. The decorative cover 700 serves both aesthetic and protective purposes. The decorative cover 700 is arc-shaped and can be placed on the exposed side of the limiting body 110 and the mounting cylinder.
[0046] Please refer to Figure 5 The tilt angle of the elastically adjustable slope 113 is 30°-50°, and the tilt angle of the folding slope 115 is 10°-35°. The elastically adjustable slope 113 has a larger tilt angle, which can ensure rapid rebound.
[0047] Please refer to Figure 5 The length of the folding slope 115 is greater than the length of the elastic adjustment slope 113. Normally, folding requires a rotation of 80-100°, and a longer length ensures proper folding.
[0048] Please refer to Figure 5 The tilt angle of the elastic adjustment limiting surface 112 is 70°-90°. The large contact release area of the inclined surface can play a protective role. Even if too much force is applied, the sliding protrusion 410 will move along the inclined surface to make the sliding body 400 continue to move backward.
[0049] Please refer to Figure 5 The length of the elastic adjustment slope 113 is greater than the length of the elastic adjustment limiting surface 112.
[0050] Please refer to Figures 4-6 The side of the limiting block 111 facing away from the elastic adjustment slope 113 is an inclined surface. One side of the sliding protrusion 410 is adapted to the inclined surface, and the other side is adapted to the elastic adjustment limiting surface 112. That is, both sides of the limiting block 111 are inclined surfaces, and both sides can play a blocking and protective role.
[0051] Simply put, a concave valley can be set at the bottom of the folding slope 115, that is, at the end of the folding slope 115 that is far away from the limiting valley 114, as needed to improve the stability of positioning.
[0052] Generally, the limiting body 110 extends into the mounting cylinder 210, and the side of the limiting body 110 facing away from the sliding body 400 is provided with an end cap 130, the outer diameter of the end cap 130 being larger than the inner diameter of the mounting cylinder 210.
[0053] The elastic element 500 is generally a spring, but other elastic elements 500 can also be used as needed.
[0054] Understandably, the sliding body 400 can be integrated with the rotating cylinder of the mounting cylinder 210 through a non-circular fit or a convex-groove fit.
[0055] Understandably, one of the fixed base 100 and the movable base 200 is connected to the frame of the glasses, and the other is connected to the temple of the glasses.
[0056] Generally, when the sliding protrusion 410 is located within the limiting valley 114, the angle between the fixed seat 100 and the movable seat 200 is 170° to 190°, preferably 180°. Please refer to [reference needed]. Figure 10 In the normal state, the temples of the glasses are in the normally open position; when the sliding protrusion 410 is located at the bottom of the folding slope 115, i.e., the end away from the limiting valley 114, the angle between the fixed seat 100 and the movable seat 200 is 70°-100°, preferably 85°. Please refer to... Figure 10 In the folded state, the temples of the glasses are folded. For a preferred option, please refer to... Figure 10 In the extreme state, when the sliding protrusion 410 is located at the end of the elastic adjustment slope 113 away from the limiting valley 114, that is, when the sliding protrusion 410 is in contact with the elastic adjustment limiting surface 112, the angle between the fixed seat 100 and the movable seat 200 is 190° to 200°.
[0057] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0058] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0059] In summary, the hinge module for AI glasses provided by this utility model has two symmetrically arranged limiting blocks in the limiting body. Each limiting block has sequentially extending elastic adjustment limiting surface, elastic adjustment slope, limiting valley, and folding slope. The sliding body approaches the limiting body under the push of the elastic element. When the movable seat rotates, it drives the sliding body to rotate. When the sliding protrusion of the sliding body is on the side elastic adjustment limiting surface, it will form a blockage. When the sliding protrusion is on the elastic adjustment slope, the sliding protrusion tends to slide towards the limiting valley. At this time, the two temples of the glasses also tend to move inward, making the wearing stable. When the sliding protrusion is in the limiting valley, the two are positioned and cooperate. When the sliding protrusion is on the folding slope, the sliding protrusion will continue to slide downward to the bottom of the folding slope. The elastic element does not directly provide inward restoring force, but relies on the cooperation between the limiting body and the sliding body, which can improve the service life. The clamping force of the temples is appropriate, the wearing is comfortable, the temples will automatically rebound to form a clamping force when they expand outward, and the temples will automatically retract when they fold inward, making it convenient to use.
