The lens 100 has a lens surface 110, a support assembly, a locking portion 123, two hinges 130, two buckle portions 131 and a nose pad engaging portion 111. The support assembly is disposed on a long side of the lens surface 110 and extends along a length direction of the lens 100 to buckle and/or lock the lens 100 in the flexible spectacle frame 200. The locking portion 123 is located on the upper side of the lens 100, preferably, the locking portion 123 is located on the upper side of the lens 100 and at a position corresponding to the midpoint between the two eyes of the user, such as a position near the brow of the user, but the invention is not limited thereto. The lens 100 has a hinge 130 and a buckle 131 on each side thereof, wherein the hinge 130 is biased toward the upper side of the lens 100, and the buckle 131 is biased toward the lower side of the lens 100. The nose pad engaging portion 111 is in an inverted V-shaped shape and is opposite to the locking portion 123.

The supporting assembly may further include a first supporting arm 121 and a second supporting arm 122 symmetrically arranged on the upper side of the lens 100; preferably, the first supporting arm 121 and the second supporting arm 122 are symmetrically arranged with respect to the locking portion 123. It is worth mentioning that the first supporting arm 121 and the second supporting arm 122 are integrally formed and extend from the center of the lens 100 to the left and right sides, and there is a gap between the first supporting arm 121 and the second supporting arm 122 and the lens 100 in the vertical direction. The supporting assembly may further include one or more supporting arms at the lower side of the lens 100. In the embodiment of the present invention, four symmetrically arranged supporting arms are used as an example (a third supporting arm 132, a fourth supporting arm 133, a fifth supporting arm 134 and a sixth supporting arm 135). In practice, the number of supporting arms may be increased or decreased according to demand, and the present invention is not limited thereto. For example, only the third supporting arm 132 or only the third supporting arm 132 and the fifth supporting arm 134 may be provided. Preferably, the third supporting arm 132 and the fourth supporting arm 133 form a group, and the fifth supporting arm 134 and the sixth supporting arm 135 form a group. The two groups of supporting arms can be L-shaped structures facing the left and right sides of the lens 100 respectively.

The flexible spectacle frame 200 is disposed around the lens 100, and includes a frame body 201, a first fixed arm 210, a second fixed arm 220, a nose pad groove 230, a third fixed arm 240, and a fourth fixed arm 250. The first fixed arm 210, the second fixed arm 220, the third fixed arm 240, and the fourth fixed arm 250 extend along a first direction of the frame body 201, and the first direction may be a length direction or a width direction of the flexible spectacle frame 200. In this embodiment, the first direction is the length direction of the flexible spectacle frame 200, that is, the left-right direction. In addition, by the way, the first fixed arm 210 and the second fixed arm 220 are symmetrically arranged, and the third fixed arm 240 and the fourth fixed arm 250 are symmetrically arranged; and, in the following text, for the symmetrically arranged components or structures, if one of the components or structures is described, the other symmetrical component or structure will not be described again.

The nose pad groove 230 is disposed directly below the flexible eyeglass frame 200 and corresponds to the nose pad engaging portion 111. The nose pad groove 230 is bent in an inverted V shape to fit the nose bridge of the user, so that the eyeglass structure 10 is fixed on the nose bridge of the user when worn. The outer surfaces of both ends of the nose pad groove 230 are each provided with one or more blind holes to correspond to one or more anchors for engaging the lens 100. The drawings of the present invention take a combination of two pairs of blind holes and anchors as an example (i.e., the first anchors 113 on the left and right sides of the drawing are respectively engaged with the first blind holes 231 on the left and right sides of the drawing, and the second anchors 114 on the left and right sides of the drawing are respectively engaged with the first blind holes 231 on the left and right sides of the drawing). The number of the first blind holes 231 and the second blind holes 232 may be increased or decreased according to the actual needs. For example, only a pair of the first anchor 113 and the first blind hole 231 may be provided on the left and right sides, only a pair of the second anchor 114 and the second blind hole 232 may be provided on the left and right sides, or only one first anchor 113 and one first blind hole 231 may be provided on the right side and one second anchor 114 and one second blind hole 232 may be provided on the left side. Therefore, the present invention is not limited thereto.

The frame body 201 of the flexible eyeglass frame 200 has a flexible surface that can be deformed to fit the eye socket of a user to provide a better fit, completely cover the eye socket of the user, conform to ergonomic characteristics, and prevent light from irradiating the eyes through the gap, thereby preventing light leakage.

The frame body 201 may further include a first fixing groove 211, a second fixing groove 221, a third fixing groove 241 and a fourth fixing groove 251, which are respectively arranged corresponding to the first fixing arm 210, the second fixing arm 220, the third fixing arm 240 and the fourth fixing arm 250. That is, the first fixing groove 211 and the second fixing groove 221 are symmetrically arranged, and the third fixing groove 241 and the fourth fixing groove 251 are symmetrically arranged. When the first supporting arm 121 is accommodated in the first fixing groove 211, the gap between the first supporting arm 121 and the lens 100 can be engaged with the bottom surface of the first fixing groove 211 (i.e., the connecting portion between the first fixing arm 210 and the frame body 201). When the lower edge of the lens 100 is received in the third fixing groove 241, the third supporting arm 132 and the fourth supporting arm 133 are engaged in the notches of the third fixing groove 241 corresponding to the third supporting arm 132 and the fourth supporting arm 133. In addition, one end of the first fixing arm 210 and one end of the third fixing arm 240 can be integrally formed to form a C-shaped frame structure, so that the fixing arms on both sides can form a C-shaped frame structure disposed opposite to each other.

The flexible spectacle frame 200 has a first through hole 202 and a second through hole 203 on both sides; the first through hole 202 is close to the upper side, and the second through hole 203 is close to the lower side. Therefore, the hinges 130 on both sides of the lens 100 can pass through the first through holes 202 on both sides of the flexible spectacle frame 200, respectively, and extend from the flexible spectacle frame 200 to connect to the lens legs 500. Similarly, the buckle portions 131 on both sides of the lens 100 can pass through the second through holes 203 on both sides of the flexible spectacle frame 200, respectively, and limit the degree of freedom of the flexible spectacle frame 200 from bottom to top. Thereby, the separation of the flexible eyeglass frame 200 and the lens 100 can be further prevented. Incidentally, the hinge portion 130 may have a hinge hole 141. During assembly, the hinge portion 130 is hinged to a hinge slot 510 of the temple 500, for example, one end of the rotating shaft is fixed to the upper side of the temple 500, and the other end of the rotating shaft passes through the shaft hole 511 on the upper side of the hinge slot 510 and then passes through the hinge hole 141, and is fixed to the shaft hole 511 on the lower side of the hinge slot 510 (for example, locked and fixed).

The flexible eyeglass frame 200 is a wrap-around one-piece molding design, and the flexible eyeglass frame 200 is made of a flexible soft rubber material, and the flexible soft rubber material includes but is not limited to: flexible polyvinyl chloride (PVC), silicone, ethylene vinyl acetate (EVA), polyoxyethylene (POE), thermoplastic elastomer (TPR or TPES), polyethylene (PE), polypropylene (PP), and rubber.

The locking shaft 300 is accommodated in the upper side of the flexible eyeglass frame 200. The locking shaft 300 has an L-shaped locking portion 310 and a shaft 320. The L-shaped locking portion 310 is arranged in the middle of the shaft 320 corresponding to the locking portion 123. The L-shaped locking portion 310 is provided with a locking hole 311. When the L-shaped locking portion 310 is accommodated in the flexible eyeglass frame 200, the locking hole 311 is engaged with the locking portion 123 of the lens 100 to prevent the flexible eyeglass frame 200 and the lens 100 from being separated from each other. The two ends of the shaft 320 are symmetrically provided with a first fixing block 330 and a second fixing block 340. The first fixing block 330 and the second fixing block 340 are substantially formed into a hook-shaped structure; correspondingly, there is a stepped first fixing portion 124 between the lens 100 and the first supporting arm 121, and a stepped second fixing portion 125 between the lens 100 and the second supporting arm 122. During assembly, the first fixing block 330 passes through the first fixing block opening 204 of the flexible eyeglass frame 200, and the first fixing portion 124 is buckled by the hook-shaped structure, so that the lens 100 is further fixed to the flexible eyeglass frame 200.

The eyeglass structure 10 may further include a nose pad 400. The nose pad 400 is disposed below the lens surface 110 of the eyeglass structure 10 and corresponds to the position of the nose pad engaging portion 111 and the nose pad groove 230. The two ends of the nose pad 400 extend downwardly at an angle. The top of the nose pad 400 has a convex block 401, and the convex block 401 limits the lens 100 between the nose pad 400 and the flexible eyeglass frame 200. The two sides of the nose pad 400 are symmetrically provided with a limiting groove 402, a locking portion 403 and a supporting member 404. One inner surface of the limiting groove 402 covers the lens 100, and the other inner surface of the limiting groove 402 is engaged with the flexible eyeglass frame 200 to buckle the lens 100 and the flexible eyeglass frame 200 together. The two engagement portions 403 are respectively engaged with the two engagement grooves 115 of the lens 100, and the two supporting members 404 are respectively engaged with the third fixing groove 241 and the fourth fixing groove 251 of the flexible eyeglass frame 200.

The beneficial effect of the present invention is to provide a flexible eyeglass frame and an eyeglass structure including the same. The flexible eyeglass frame is mutually locked with a supporting arm of a lens through a plurality of fixed arms, so that the lens is engaged in a fixed groove of the flexible eyeglass frame, so that the eyeglass structure can be effectively and easily assembled, and the lens is not easily displaced or separated due to external force, thereby improving the durability of the eyeglass structure. In addition, the flexible eyeglass frame is a wrap-around one-piece molding design, and the flexible eyeglass frame is made of a flexible soft rubber material, so that the wearer feels comfortable when it touches the face, thereby achieving the effect of being compliant with the face.
