Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically, to an elastic temple structure and eyeglasses. Background Technology

[0002] There are significant differences in head circumference between men and women in China, both between the north and south. Therefore, eyewear manufacturers currently need to develop eyeglasses in sizes to meet the specific needs of different head circumferences, which involves relatively high development costs and time.

[0003] To prevent sports glasses from slipping off during use and causing injuries, current solutions typically focus on increasing the clamping force of the temples through structural design to achieve a secure fit. However, this reduces wearing comfort and may cause injury to the head. Products on the market that primarily rely on increased temple clamping force for a secure fit often result in varying degrees of lens deformation, causing dizziness, blurred vision, and other adverse symptoms, thus impacting the user experience.

[0004] To address the aforementioned issues, patent application CN105487252A discloses a 360° omnidirectional bending temple for eyeglasses. Specifically, it relates to the temple structure of eyeglasses, including the temple and a mounting component. The temple and the mounting component are interconnected by a shape memory metal component, allowing the temple to bend 360° omnidirectionally with the shape memory metal component as the bending point.

[0005] However, the existing technology only provides the technical concept of setting memory metal parts on metal temples. During manufacturing, the temples need to be embedded in elastic rubber / silicone bodies. Once the shape memory metal parts are formed, they cannot be replaced, which is not conducive to adjusting the rebound torque of the moving parts. Utility Model Content

[0006] The purpose of this invention is to provide an elastic temple structure and eyeglasses made of shape memory metal to solve the problems existing in the prior art.

[0007] The purpose of this utility model is achieved as follows: an elastic temple structure made of shape memory metal, comprising a temple body, the temple body including a functional part and a movable part, and at least one detachable metal sheet made of shape memory metal material, wherein the movable part is elastically connected to the functional part through the metal sheet, so that the movable part can be adjusted to rotate left and right relative to the functional part.

[0008] Furthermore, one part of the metal sheet is detachably and fixedly connected to the functional part, and the other part is detachably and fixedly connected to the movable part.

[0009] Furthermore, the movable part is located outside the functional part, and a fulcrum protrusion is formed on the outer side of the tail end of the functional part. The movable part can be adjusted by rotating left and right with the fulcrum protrusion as the fulcrum.

[0010] Furthermore, the metal sheet is configured as a bent spring sheet, the bent area of ​​the metal sheet is fixedly covered to the tail end of the functional part, a part of the metal sheet is configured as an inner fixing part, and the other part is configured as an outer fixing part, the inner fixing part and the outer fixing part of the metal sheet are respectively fixed to the inner side of the mounting functional part and the movable part.

[0011] Furthermore, a portion of the metal sheet is detachably inserted into or attached to the functional part, and another portion of the metal sheet is detachably attached to the movable part. The connection point between the metal sheet and the functional part is located on the front side of the fulcrum protrusion. The entire metal sheet is tilted outward based on the functional part, and the fulcrum protrusion directly contacts and abuts against the movable part.

[0012] Furthermore, the front end of the movable part is positioned in front of the fulcrum protrusion.

[0013] Furthermore, the end face of the functional part is set as a curved surface and fits against the inner surface of the bending area of ​​the metal sheet.

[0014] Furthermore, the functional part is composed of a front part and a rear part, and the rear part of the functional part is bent outward based on the front part of the functional part.

[0015] As another aspect of this utility model, a pair of eyeglasses is proposed, including a lens and two elastic temple structures, wherein the front end of the functional part of the temple body is fixedly connected to the lens.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. Since the memory metal sheet connecting the elastic connection part and the movable part is detachable, the memory metal sheet can be replaced, thereby adjusting the rebound torque of the movable part, so that the fixed position of the temple can be adjusted according to the specific user's situation / needs;

[0018] 2. The shape memory metal sheet can detachably connect the functional part and the moving part. The shape memory metal sheet itself has a simple structure, which is easy to mass-produce. Its installation method is also significantly better than the existing technology, and the manufacturing cost and installation difficulty are significantly reduced. Attached Figure Description

Detailed Implementation

[0025] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] refer to Figure 1 As shown, a flexible temple structure made of shape memory metal is proposed, comprising a temple body 1, which includes a functional part 101, a movable part 102, and at least one metal sheet 2 made of shape memory metal. The movable part 102 is elastically connected to the functional part 101 via the metal sheet 2. The metal sheet 2 is designed as a one-piece shape memory metal sheet for easy mass production. One part of the metal sheet 2 is detachably and fixedly connected to the functional part 101, and the other part is detachably and fixedly connected to the movable part 102, allowing the movable part 102 to rotate left and right relative to the functional part 101 for adjustment. By using a movable temple composed of shape memory metal, the range of motion is increased, which can meet the needs of people in different sports scenarios.

[0027] A fulcrum protrusion 101b is formed on the outer side of the tail end of the functional part 101. The fulcrum protrusion 101b abuts against the movable part 102 in the outward direction. The movable part 102 rotates left and right with the fulcrum protrusion 101b as the fulcrum.

[0028] The elastic pad can be placed at the corresponding position of the movable part 102. The specific position can be determined according to project requirements and is not limited here. This reduces the probability of the product falling out of its position due to vigorous movement, while maintaining a light clamping force.

[0029] When the user wears the glasses, the movable part 102 moves elastically in the left and right directions, and at the same time, the metal piece 2 deforms accordingly. The opening angle of the movable parts 102 of the two temples is adapted to the shape of the user's head.

[0030] There are many options for the structure and detachable connection method of the metal sheet 2. For ease of description, this utility model provides two preferred embodiments.

[0031] Example 1

[0032] like Figure 1-2 As shown, in a preferred improvement, the movable part 102 is located outside the functional part 101. The bending area of ​​the metal sheet 2 is fixedly covered by the tail end of the functional part 101. The tail end surface of the functional part 101 is curved and fits against the inner surface of the bending area of ​​the metal sheet 2. One part of the metal sheet 2 is set as an inner fixing part 201, and the other part is set as an outer fixing part 202. The inner fixing part 201 and the outer fixing part 202 of the metal sheet 2 are respectively detachably fixed to the inner surfaces of the functional part 101 and the movable part 102. In this embodiment, the metal sheet 2 is set as an integral spring sheet formed by bending, which is convenient for mass production. The metal sheet 2 is similar to a V-shaped sheet structure with the opening facing forward.

[0033] As a preferred embodiment, a fulcrum protrusion 101b is formed on the outer side of the tail end of the functional part 101. The fulcrum protrusion 101b abuts against the movable part 102 in the outward direction. The movable part 102 rotates left and right with the fulcrum protrusion 101b as the fulcrum. The outer fixing part 202 of the metal sheet 2 undergoes elastic deformation relative to the functional part 101. As a structural optimization embodiment, the fulcrum protrusion 101b is set as an arc-shaped protrusion and smoothly connects to the tail end surface of the functional part 101. When worn, the movable part 102 contacts the surface of the skull and generates an adaptive deflection. The movable part 102 rotates left and right with the fulcrum protrusion 101b as the rotation fulcrum.

[0034] The movable part 102 extends forward based on the fulcrum protrusion 101b, with the front end of the movable part 102 positioned in front of the fulcrum protrusion 101b. The front end of the outer fixing part 202 is positioned forward relative to the front end of the inner fixing part 201, which allows for a larger elastic movement torque / range of the movable part 102. As a further improvement, the aforementioned functional part 101 consists of a front part and a rear part. The rear part of the functional part 101 bends outward based on the front part of the functional part 101, making the fulcrum protrusion 101b on the outer side of the tail end of the functional part 101 more outward, forming a curved groove (which can be parabolic or other curved shapes) on the outer side of the functional part 101. This limits the rotation angle of the movable part 102, preventing the movable part 102 from rotating excessively outward, which would reduce the clamping force of the movable part 102. This ensures that the movable part 102 forms sufficient clamping force when worn, allowing the movable part 102 to be firmly fixed to the surface of the skull.

[0035] As one of the preferred fixing solutions, the flexible temple structure also includes:

[0036] An external fixing screw 3 passes through the metal plate 2 and is threadedly connected to the movable part 102 to fix the position of the metal plate 2 on the movable part 102. A circular clearance hole 101a is provided in front of the external fixing screw 3 in the functional part 101. The clearance hole 101a is in front of the inner fixing part 201 and the fulcrum protrusion 101b. The inner diameter of the clearance hole 101a is larger than the outer diameter of the screw head of the external fixing screw 3. The function of the clearance hole 101a is to prevent structural interference between the external fixing screw 3 and the functional part 101 when the movable part 102 moves.

[0037] Two internal fixing screws 4 (the number is not limited) pass through the metal plate 2 and are threadedly connected to the functional part 101 to fix the position of the metal plate 2 on the functional part 101.

[0038] Based on the above-mentioned flexible temple structure, such as Figure 1 As shown, a preferred pair of eyeglasses is proposed, including a forward-curved lens 5 and two elastic temple structures. The front end of the functional part 101 of the temple body 1 is fixedly connected to the lens 5. When the user wears the glasses, the movable parts 102 of the two temple bodies 1 make pressure contact with the surface of the user's head, causing the movable parts 102 to perform elastic rotational movement in the left and right direction. At the same time, the metal plate 2 deforms accordingly. The opening angle of the movable parts 102 of the two temples is adapted to the shape of the user's head, which can effectively prevent the lens 5 from deforming and make the glasses last longer.

[0039] Example 2

[0040] like Figure 3-5 As shown, a portion of the metal sheet 2 is detachably inserted into (or attached to) the functional part 101. The specific connection point between the metal sheet 2 and the functional part 101 is not limited. The other portion of the metal sheet 2 is detachably fixedly connected to the movable part 102. The metal sheet 2 is tilted / raised outward based on the functional part 101, which makes the elastic torque of the movable part 102 greater and better ensures that the movable part 102 forms sufficient clamping force when worn, so that the movable part 102 is firmly fixed on the surface of the skull.

[0041] The specific solution of Example 2 is: through Figure 3 It can be seen that a insertion hole can be opened in the front area of ​​the fulcrum protrusion 101b of the functional part 101. A part of the metal sheet 2 is detachably inserted into the insertion hole and can be fixed by fasteners or structural self-locking (not limited here). The other part of the metal sheet 2 is detachably attached to the movable part 102. Accordingly, the fulcrum protrusion 101b directly contacts and abuts against the movable part 102, and the connection point between the metal sheet 2 and the movable part 102 is located on the front side of the fulcrum protrusion 101b. It is worth noting that the specific solution of Embodiment 2 is a preferred application example and is not limited to this solution.

[0042] In summary, the glasses designed in this way can be compatible with both round and long skull shapes, and can be used by users with different head circumferences, while maintaining minimal lens deformation.
