DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application is described clearly below in combination with specific embodiments and corresponding drawings. Obviously, the following described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. In the case of no conflict, each of the following embodiments and its technical features can be combined with each other, and also belong to the technical scheme of the present application.

[0026] In the description of the embodiments of the present application, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate the orientation or positional relationship shown in the drawings, which are only for the convenience of describing the technical scheme of the corresponding embodiments, and do not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as a limitation of the present application.

[0027] Please refer to Figures 1 to 7 , the external type vision correction safety glasses 100 of the present application can also be simply referred to as "glasses", "vision correction glasses" or "safety glasses", which includes the frame body 1 and the additional wing 2, and the additional wing 2 and the frame body 1 can be detachably assembled to realize the external type function of the glasses 100.

[0028] For the convenience of description and understanding of the scheme of the present application, in combination with the placement orientation, the width direction of the eyeglasses 100 (i.e. the so-called "lens width direction") is referred to as the first direction x, the height direction (i.e. the so-called "lens height direction") is referred to as the second direction y, and the temple length direction is referred to as the third direction z. The first direction x, the second direction y, and the third direction z are perpendicular to each other, which can be regarded as three coordinate axes of a three-dimensional orthogonal coordinate system. It should be understood that the so-called perpendicular in the present application does not require that the included angle between the two be 90°, but allows a deviation of, for example, ±10°, i.e. the so-called perpendicular can be understood as the included angle between any two directions being 80° to 100°. Similarly, the so-called parallel in the present application does not require that the included angle between the two be 0° or 180°, but allows a deviation of, for example, ±10°, i.e. the so-called parallel can be understood as the included angle between any two directions being 0° to 10° or 170° to 190°.

[0029] The frame body 1 includes a frame 11 and two temples 12, which can be generated, sold, assembled and transported as a single pair of eyeglasses. The two temples 12 are oppositely arranged on both sides of the frame 11 along the first direction x, and each temple 12 can rotate relative to the frame 11 towards the inner side of the eyeglasses 100, and the so-called inner side can be understood as the side facing the face when the eyeglasses 100 are worn on the user. The frame 11 can be mounted with lenses for vision correction, also known as vision correction lenses.

[0030] For any one of the temples 12, the upper side (the side above along the second direction y) and the lower side (the side below along the second direction y) of the temple 12 are respectively provided with a first sliding groove 120, which is arranged along the extension direction of the temple 12. It should be noted that, in order to adapt to the face of the wearer, the extension direction of the temple 12 is not parallel to the third direction z, but forms an acute angle with the third direction z, and gradually extends from the frame 11 towards the inner side of the eyeglasses 100.

[0031] The number of additional wings 2 can be the same as the number of temples 12, for example Figure 1 and Figure 2 The two additional wings 2 shown can be detachably assembled to the two temples 12, of course, the number of additional wings 2 can be less than the number of temples 12, for example, only one additional wing 2 is provided.

[0032] A single additional wing 2 includes a wing top 20, a first wing side 21 and a second wing side 22, the wing top 20 and the second wing side 22 are respectively in a sheet structure or a wing structure, and the first wing side 21 can be in a strip structure and is connected between the wing top 20 and the second wing side 22. In combination with Figure 1 , Figure 2 and Figure 6As shown, the shapes of the wing top 20 and the second wing side 22 can be similar to triangles, so that the radial dimension of the additional protective wing 2 decreases from thick to thin along the third direction z. A first slide rail 231 is provided at the junction of the wing top 20 and the first wing side 21, and a second slide rail 232 is provided at the junction of the second wing side 22 and the first wing side 21. The first slide rail 231 and the second slide rail 232 are arranged vertically opposite each other along the second direction and are parallel to the first wing side 21, thereby forming a groove between the track surface of the first slide rail 231 and the second slide rail 232 and the first wing side 21.

[0033] First, insert the temple 12 into the notch at the junction of the top wing 20 and the second wing side 22 along the third direction z. During insertion, slide the first slide rail 231 and the second slide rail 232 along the extension direction of the temple 12 into the corresponding first slide groove 120. That is, slide the first slide rail 231 into the upper first slide groove 120 and slide the second slide rail 232 into the lower first slide groove 120. The first wing side 21 is positioned opposite to the outer side of the temple 12. In other embodiments, the first wing side 21 can be fitted to the outer side of the temple 12 so that the additional wing 2 is mounted on the corresponding temple 12, thereby completing the assembly of the additional wing 2 and the frame body 1. By separating the aforementioned corresponding components, the additional wing 2 and the frame body 1 can be separated.

[0034] This application uses a sliding rail and a sliding groove 120 to attach the additional protective wing 2 to the frame body 1 of the glasses 100. The external connection structure is simple, and the connection and disassembly operations are relatively easy.

[0035] When the additional protective wings 2 are assembled with the frame body 1 and worn on the user's face, the top 20 of the wing can fit snugly against the user's forehead or brow bone area, while the first wing side 21 and the second wing side 22 can fit snugly against the user's corners of the eyes and lower eyelids, thus protecting the user's eyes from all four sides. Therefore, the corrective glasses 100 of this application are well-suited for visually impaired users and provide good eye protection.

[0036] Combined Figures 3 to 7As shown, an elastic element 211 can be provided on the side of the first wing side 21 facing the temple 12. A second sliding groove 121 and a receiving hole 122 are provided on the outer side of the temple 12. The second sliding groove 121 allows the elastic element 211 to slide along the second sliding groove 121. The receiving hole 122 allows the elastic element 211 to be engaged in the receiving hole 122 when it slides to the position of the receiving hole 122. Thus, by engaging and inserting the elastic element 211 into the receiving hole 122, the additional protective wing 2 stops sliding relative to the temple 12, and a relatively stable assembly is achieved between the additional protective wing 2 and the frame body 1.

[0037] In one example, the elastic element 211 can be an elastic column with a diameter greater than the width of the second groove 121. In its natural, unforced state, the elastic element 211 has a maximum protruding length along the first direction x. During the sliding of the additional wing 2 relative to the temple 12, the elastic element 211 is subjected to the force from the outer sides of the temple 12 on both sides of the second groove 121, causing it to contract towards the outer side of the temple 12. This results in the elastic element 211 having a length along the first direction x that is less than the maximum length. When the elastic element 211 reaches the location of the receiving hole 122, the force is eliminated, and the elastic element 211 extends and engages in the receiving hole 122.

[0038] Optionally, the center of the receiving hole 122 is located within the second slide groove 121, for example, the center of the receiving hole 122 is located on the bisector of the second slide groove 121.

[0039] Continue reading Figure 4 and Figure 5 As shown, a third sliding groove 233 may be provided at the junction of the frame 11 and the temple 12. The third sliding groove 233 is aligned with and communicates with the second sliding groove 121. The frame 11 includes not only an eye frame body that surrounds and forms the mounting of the corrective lens, but also an extension 110 that is combined with the temple 12. The extension 110 extends to the side where the temple 12 is located and is movably connected to the temple 12 on that side. When the extension 110 and the temple 12 are located in the same extending direction, the third sliding groove 233 is aligned with and communicates with the second sliding groove 121, which is equivalent to increasing the length of the second sliding groove 121. This allows the elastic element 211 to slide in advance along the extending direction of the second sliding groove 121, facilitating subsequent sliding assembly.

[0040] Please combine them together Figure 4 , Figure 5 and Figure 6As shown, the first slide groove 120 extends to the junction of the temple 12 and the frame 11. During the sliding process of the additional wing 2 relative to the temple 12, once the first slide rail 231 and the second slide rail 232 can abut against the frame 11, the additional wing 2 can be blocked from sliding relative to the temple 12. At this time, the user can know that the predetermined sliding position has been reached. The elastic element 211 is automatically locked in the receiving hole 122, and the additional wing 2 is assembled with the frame body 1 and its temple 12.

[0041] The first wing side portion 21 extends to the plane of the frame 11 and bends to form a blocking portion 212. This blocking portion 211 is located outside the area of ​​the frame 11 where the corrective lens is installed to avoid affecting the user's field of vision. During the sliding of the additional wing 2 relative to the temple 12, once the blocking portion 212 abuts against the frame 11, it can prevent the additional wing 2 from sliding relative to the temple 12. At this time, the user can also know that the predetermined sliding position has been reached. The elastic element 211 automatically engages in the receiving hole 122, and the additional wing 2 is assembled with the frame body 1 and its temple 12. Of course, in other examples, the blocking portion 212 may not be provided, and the predetermined sliding position may be known only by the first slide rail 231 and the second slide rail 232 abutting against the frame 11.

[0042] Please continue reading. Figures 1 to 7 The second wing side 22 extends from the blocking part 212 along the side of the frame 11 to a part of the bottom of the frame 11. It can cover the user's corner of the eye and the area where the lower eyelid is located to the maximum extent, improving the eye protection effect, without obstructing the user's field of vision. The second wing side 22 can abut against the side and bottom of the area of ​​the frame 11 where the corrective lens is installed, preventing the additional protective wing 2 from continuing to slide relative to the temple 12.

[0043] Similarly, the first wing side 21 extends from the blocking part 212 to a part of the top of the frame 11, which can cover the user's forehead or brow bone area to the greatest extent, improve the eye protection effect, and will not obstruct the user's field of vision. In addition, the first wing side 21 can abut against the upper part of the area of ​​the frame 11 where the corrective lens is installed, preventing the additional protective wing 2 from continuing to slide relative to the temple 12.
