Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to an eyeglass and its hinge structure. Background Technology

[0002] With the rapid development of AR smart glasses, users' demands for wearing comfort and lightweight design are increasing. However, the circuit boards, batteries, and other electronic components integrated inside the temples limit their deformation capabilities, causing the clamping force to rely on the limited deformation of the frame. Since the display module is embedded in the frame, excessive deformation can compress optical components (e.g., causing image distortion). With frame deformation limited, the hinge becomes the core of mechanical support, needing to simultaneously meet the following requirements: 1. Stably maintain the open / folded state of the temples (anti-sway); 2. Achieve automatic temple reset. However, existing hinge structures (such as the existing patent CN202311553405) have defects: the temples lack a stable locking mechanism in the open or folded state, making them prone to swaying and wear under external force disturbances. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide eyeglasses and their hinge structure, which can improve the stability of the temples and reduce swaying, enhance the rebound mechanism, simplify the structure and improve durability.

[0004] To solve the above-mentioned technical problems, the first aspect of this utility model discloses a hinge structure for eyeglasses, comprising:

[0005] A fixing base is fixed to the mirror frame, and the fixing base is provided with a through hole;

[0006] Screws and nuts, passing through the through hole, are used to provide a mechanical connection;

[0007] The damping element is fixed to the fixed base by the screws and nuts, and the outer wall of the damping element is a rounded rectangular prism;

[0008] The spring clip is mainly located inside the temple, with one end exposed and bent into a rounded rectangular sleeve. This sleeve structure is fitted onto the outer surface of the damping component to achieve a rotating connection of the temple.

[0009] A spring ball is embedded in the groove of the fixed base, with the top of the ball in close contact with the outer surface of the sleeve structure of the spring piece;

[0010] When the temple rotates, the rounded rectangular outer wall of the damping element provides two contact points, and the spring ball provides a third contact point. The three together compress the sleeve structure, causing it to elastically deform and store energy for rebound.

[0011] As an optional implementation, the damping element is made of POM material.

[0012] As another optional implementation, the outer wall of the rounded rectangular column of the damping member is clearance-fitted with the inner wall of the sleeve structure.

[0013] As another alternative implementation, the spring is made of β-titanium.

[0014] As another alternative implementation, the screw is a 1.4mm machine screw.

[0015] As another optional implementation, the fixing base is made of aluminum alloy.

[0016] The second aspect of this utility model discloses a pair of eyeglasses, including a frame, temples, and a hinge structure as described in the first aspect of this utility model.

[0017] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0018] This utility model embodiment can improve the stability of the temples and reduce swaying: the spring ball design can limit the swaying of the temples in the open and folded states. Combined with the cooperation of the damping element and the spring, it ensures that the temples remain fixed in the open or folded state, avoiding damage to the smart glasses due to accidental shaking (such as damage to the display module inside the frame); it can also enhance the rebound mechanism: through three-point compression (two points of the damping element and one point of the spring ball) energy storage, the spring automatically rebounds after rotation, realizing the rapid return of the temples to the open state; it can also simplify the structure and improve durability: screws and nuts provide reliable mechanical connection, and the fixed base integrates a groove design, making the overall structure compact.

[0026] Example 1

[0027] See Figures 1-5 This utility model discloses a hinge structure for eyeglasses, comprising:

[0028] A fixing base 3 is fixed on the mirror frame 1, and the fixing base 3 is provided with a through hole 32;

[0029] Screw 4 and nut 5 are inserted through the through hole 32 to provide a mechanical connection;

[0030] The damping element 6 is fixed to the fixed base 3 by the screw 4 and nut 5, and the outer wall of the damping element 6 is a rounded rectangular prism;

[0031] The spring piece 7 is mainly located inside the temple 2, with one end exposed and bent into a rounded rectangular sleeve 71. This sleeve structure 71 is fitted onto the outer surface of the damping member 6 to realize the rotational connection of the temple 2.

[0032] Spring ball 8 is embedded in the groove 31 of the fixed base 3, and the top of the ball is in close contact with the outer surface of the sleeve structure 71 of the spring piece 7.

[0033] Among them, see Figure 5 (The temple of the glasses is rotated 45 degrees in the figure). When the temple 2 rotates, the rounded rectangular outer wall of the damping element 6 provides two contact points, and the spring ball 8 provides a third contact point. The three of them together compress the sleeve structure 71, causing it to elastically deform and store energy to rebound.

[0034] This utility model embodiment can improve the stability of the temple 2 and reduce swaying: the design of the spring ball 8 can limit the swaying of the temple 2 in the open and folded states. Combined with the cooperation of the damping element 6 and the spring piece 7, it ensures that the temple 2 remains fixed in the open or folded state, avoiding damage to the smart glasses due to accidental shaking (such as damage to the display module inside the frame 1); it can also enhance the rebound mechanism: through three-point compression (two points of the damping element 6 and one point of the spring ball 8) energy storage, the spring piece 7 automatically rebounds after rotation, realizing that the temple 2 quickly returns to the open state; it can also simplify the structure and improve durability: the screw 4 and nut 5 provide a reliable mechanical connection, and the fixed base 3 integrates the groove 31 design, making the overall structure compact.

[0035] In an optional embodiment, the damping element 6 is made of POM material. Polyoxymethylene (POM) material has a low coefficient of friction and wear resistance.

[0036] In another optional embodiment, the outer wall of the rounded rectangular column of the damping element 6 is clearance-fitted with the inner wall of the sleeve structure 71. This clearance fit maintains the stability of the two-point contact of the damping element 6 while preventing excessive deformation of the sleeve 71, optimizing rotational smoothness, and improving the user experience.

[0037] In another optional embodiment, the spring 7 is made of β-titanium. β-titanium has a high elastic modulus and superelastic properties.

[0038] In yet another alternative embodiment, the screw 4 is a 1.4mm machine screw 4.

[0039] In another optional embodiment, the fixing base 3 is made of aluminum alloy. Aluminum alloy is lightweight and high-strength, which reduces the weight of the hinge structure and improves wearing comfort. At the same time, aluminum alloy is corrosion-resistant and impact-resistant, protecting the internal components.
