Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically, to a detachable eyeglass frame for improving the fit of eyeglasses. Background Technology

[0002] Currently, most detachable frames on the market are decorative designs, lacking optimization for fit and functional improvements. To make sports glasses fit the face better, improve coverage, and reduce wind resistance, frames and temples with a large curvature are used. The front end of the temple is connected to the frame, and the front and rear ends of the temple bend outwards and then inwards to close together.

[0003] An existing technology provides a pair of sports glasses, authorized by publication number CN222599975U, including a frame and two temples connected to the frame. The temples include a connecting section, a bending section, and an ear loop section connected sequentially. The front end of the connecting section is connected to the frame, the front end of the bending section is connected to the rear end of the connecting section, and the front end of the ear loop section is connected to the rear end of the bending section. The bending section bends inward from its front end to its rear end, and the front end of the ear loop section is the ear loop position on the temple. By bending inward from the front end to the rear end of the bending section, the front end of the ear loop section connected to the rear end of the bending section is tightened inward, and the front end of the ear loop section is the ear loop position. This allows for a better fit to the ear when worn, reducing the gap between the front end of the ear loop section and the contact point with the ear, and improving wearing stability. However, this existing technology still has problems such as insufficient fit, poor wind protection, limited usability in certain scenarios, and poor ventilation. Utility Model Content

[0004] The purpose of this invention is to provide a detachable eyeglass frame to improve the fit of eyeglasses, thereby solving the problems existing in the prior art.

[0005] The purpose of this utility model is achieved as follows: a detachable eyeglass frame for improving the fit of eyeglasses, comprising an eyeglass frame body that is detachably attached to the lens, the eyeglass frame body being made of thermoplastic elastic material, and the eyeglass frame body forming an elastically deformable structure after being attached to the lens;

[0006] The frame body has a rear protrusion on the side facing the human body. The rear protrusion extends along the length of the frame body and is located directly above the bridge of the nose. The rear protrusion has multiple vertical through holes, and the length of the through holes follows the extension direction of the rear protrusion.

[0007] The beneficial effects of this utility model are as follows:

[0008] 1. The frame body is made of thermoplastic elastic material with certain strength and elasticity. After the frame body and the lens are combined, they form an elastically deformable structure, which optimizes the contact area between the frame body and the facial contour, enhances the fit and comfort. The frame body made of thermoplastic elastic material is compatible with the lens, which can enhance the stability of the overall product and prevent the lens from damaging the face in case of improper use or accidents, thus improving the safety of use.

[0009] 2. The upper edge of the frame body has a raised section on the side facing the wearer's face, which fits snugly against the wearer's face. A through-hole is provided in this raised section, serving the following functions: First, it creates a guiding effect, directing airflow encountered during the wearer's movement to the inner surface of the lens, effectively preventing fogging and enhancing anti-fog performance; second, it has a wind-dispersing function, effectively dispersing wind during product use; and third, it appropriately reduces and controls the hardness of the raised section, making the wearer's experience more comfortable.

Detailed Implementation

[0015] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 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.

[0016] like Figure 1 , 3As shown, to overcome the problems of insufficient fit, poor wind protection, limited application scenarios, and poor ventilation in existing eyewear products, a detachable frame is proposed to improve the fit of eyewear. This frame includes a frame body 1 that is detachably attached to a lens 2. The frame body 1 is made of a thermoplastic elastic material with a certain strength and elasticity. After the frame body 1 and lens 2 are combined, they form an elastically deformable structure (curving forward and elastically deformable in the front-back direction), optimizing the contact area between the frame body 1 and the facial contour, enhancing the fit. The frame body 1, made of thermoplastic elastic material, is compatible with the lens 2 (which also has a certain degree of elasticity), strengthening the overall stability of the product. It also prevents injury to the face from the lens 2 in case of improper use or accidents, improving safety.

[0017] The frame body 1, made of thermoplastic elastic material, is elastic, so it can deform and return to its undeformed state during use and disassembly.

[0018] A raised portion 107 (rigid TPU) is fixedly provided on the side of the upper edge of the frame body 1 that conforms to the wearer's face. The raised portion 107 extends along the length of the upper edge of the frame body 1 and is located directly above the bridge of the nose. The main contact surface is located in the area between the left and right brow bones. The other parts of the upper edge of the frame body 1 contact the brow bone area (only contact, not press). The raised portion 107 has multiple vertically penetrating strip-shaped through holes 107a. The length direction of the through holes 107a follows the extension direction of the raised portion 107, and the through holes 107a are also arc-shaped. The through holes 107a play the following roles: firstly, they provide ventilation, guiding the airflow encountered by the wearer during movement to the inner surface of the lens 2, effectively preventing fogging of the lens 2 and enhancing anti-fog performance; secondly, they have a wind-dispersing function, effectively dispersing wind force during product use; and thirdly, they appropriately reduce and control the hardness of the raised portion 107, making the wearer's wearing experience more comfortable.

[0019] When the frame body 1 comes into contact with the user and enters the wearing state, at least one part of the frame body 1 comes into contact with the face and undergoes elastic deformation.

[0020] like Figure 1 , 2 As shown, the frame body 1 and the lens 2 are curved forward in an arc shape. The frame body 1 is designed as an open rod-shaped structure extending along the outer contour edge of the lens 2, and an opening is formed on the lower side of the frame body 1 to accommodate the lens 2.

[0021] The frame body 1 described above consists of the following parts:

[0022] The upper edge 101 is fixedly connected to the upper edge of the lens 2;

[0023] The two side positioning parts 103 are distributed on the left and right sides, and the side positioning parts 103 are fixedly connected to the side edge of the lens 2.

[0024] The lower support 104 is distributed on the left and right sides and is fixedly connected to the bottom edge of the lens 2, so as to support the lens 2.

[0025] Among them, such as Figure 4 As shown, the upper front side of the upper edge 101 is provided with a forward-convex edge 101a, and the forward-convex edge 101a is connected to the front surface of the upper edge 101 by an arc-shaped transition surface, so that the structural strength of the upper edge 101 and the entire frame body 1 can be improved.

[0026] like Figure 2 As shown, the junction of the upper end of each side positioning part 103 and the upper edge part 101 is provided as an upper curved transition section 102, and the junction of the lower end of each side positioning part 103 and the lower support part 104 is provided as a lower curved transition section 106. The upper curved transition section 102 and the lower curved transition section 106 can enhance the structural strength of the entire frame body 1.

[0027] As a preferred method for fixing the lens 2, the inner edge of the frame body 1 is provided with a lens locking groove 105. The lens locking groove 105 passes through the upper edge 101, the upper curved transition section 102, the side positioning section 103, the lower curved transition section 106 and the lower support section 104. The lens 2 is detachably fixed and inserted into the lens locking groove 105. The end of the lens locking groove 105 is an open structure to facilitate the installation of the lens. The frame body 1 is equivalent to an irregular rod-shaped structure. The lens locking groove 105 is opened on the inner edge of the frame body 1 to cover and lock the edge of the lens 2.
