[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figure 1-6 A lens assembly, comprising:

[0031] The main body of the light-transmitting lens 1 has a support frame 2 fixedly connected to one side of the top of the main body of the light-transmitting lens 1, and mounting holes 3 are opened at both ends of the support frame 2.

[0032] The light-shielding lens body 4 has a notch 5 at one end near the mounting hole 3. Both ends of the notch 5 are fixedly connected to the mounting shaft 6, and the two mounting shafts 6 are respectively mounted inside the two mounting holes 3.

[0033] Positioning component 7 is assembled between mounting hole 3 and mounting shaft 6 to lock the position of light-shielding lens body 4.

[0034] In this embodiment, the side of the support frame 2 near the notch 5 and the side of the light-shielding lens body 4 near the light-transmitting lens body 1 are both provided with arc surfaces. By providing arc surfaces, interference between the mounting hole 3 and the flipping of the light-shielding lens body 4 can be avoided, thus ensuring the flipping effect of the light-shielding lens body 4.

[0035] In this embodiment, the materials of the light-transmitting lens body 1 and the light-blocking lens body 4 can be:

[0036] Synthetic resin: It is lightweight, comfortable to wear, has strong impact resistance and is not easily broken, has good light transmission, and is easy to process and reprocess.

[0037] Polycarbonate: Characterized by high toughness and resistance to breakage, it effectively prevents lenses from shattering during vigorous exercise. PC lenses are lightweight, have good light transmission, and also offer excellent UV protection.

[0038] More specifically, the dye color of the main body 4 of the light-blocking lens can be:

[0039] Gray: Absorbs visible light uniformly, resulting in high color fidelity;

[0040] Brown: Filters blue light and improves contrast in foggy or polluted environments;

[0041] Green: Reduces eye strain, suitable for prolonged outdoor activities;

[0042] These are mature existing technologies, and will not be elaborated upon here;

[0043] Example 2:

[0044] Please see Figure 1-6 This embodiment provides a technical solution based on Embodiment 1: the positioning component 7 includes:

[0045] Two locking plates 8 are fixedly connected to the inside of the mounting hole 3. Each locking plate 8 has a locking groove 9. A set of limiting protrusions 10 are provided at the top and bottom of the locking groove 9.

[0046] Eccentric plate 11 is fixedly connected to one end of the assembly shaft 6 located inside the bearing frame 2. The end of the eccentric plate 11 away from the assembly shaft 6 is fixedly connected to a locking rod 12, and the locking rod 12 is also movably connected inside the locking groove 9.

[0047] In this embodiment, the assembly shaft 6 and the mounting hole 3 are in transition fit. Through the structural fit between the assembly shaft 6 and the mounting hole 3, the rotational friction of the assembly shaft 6 can be greatly improved, and the position of the light-shielding lens body 4 can be initially locked when the rotation of the light-shielding lens body 4 stops.

[0048] In this embodiment, both the locking plate 8 and the locking groove 9 are arc-shaped structures. The locking plate 8 is fixedly connected to the inner side of the mounting hole 3 by a bracket. Through the structural cooperation of the locking plate 8 and the locking groove 9, the rotation trajectory of the locking rod 12 can be better matched, ensuring the connection effect with the locking rod 12. Furthermore, by positioning the locking plate 8 by the bracket, the stability of the locking plate 8 in use can be guaranteed, and uncontrollable shaking of the locking plate 8 during use can be avoided.

[0049] In this embodiment, there are two limiting protrusions 10, and the two limiting protrusions 10 are located on both sides of the inner wall of the locking groove 9. The cross-sectional shape of the limiting protrusion 10 is semi-circular. Through the structural characteristics of the limiting protrusion 10, interference can be reduced when the locking rod 12 contacts the limiting protrusion 10. At the same time, the locking plate 8 and the limiting protrusion 10 can both be made of plastic. Through the material characteristics of the locking plate 8 and the limiting protrusion 10, the locking groove 9 can be expanded when the locking rod 12 passes through the limiting protrusion 10, which will increase the distance between the two limiting protrusions 10 until the locking rod 12 can pass through. After the locking rod 12 passes between the limiting protrusions 10, the limiting protrusions 10 lose their squeezing force, and the locking rod 12 can be limited to the end of the locking groove 9 by the reset of the locking groove 9 in conjunction with the limiting protrusion 10.

[0050] In this embodiment, wear-resistant layers are fixedly connected to the inside of the locking groove 9 and the outside of the locking rod 12. By setting the wear-resistant layer, the wear when the locking rod 12 contacts the locking groove 9 can be reduced, which greatly improves the service life of the locking rod 12 and the locking plate 8. The material of the wear-resistant layer can be rubber.

[0051] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0052] Working principle: The main body 1 of the light-transmitting lens is installed on the frame. When the light is dim, the main body 4 of the light-blocking lens is pushed upward, causing it to rotate under the support of the mounting shaft 6. The mounting shaft 6 and the locking plate 8 are connected, and as the mounting shaft 6 rotates, the locking rod 12 moves synchronously within the locking groove 9. As the main body 4 of the light-blocking lens continues to rotate, the locking rod 12 contacts one of the limiting protrusions 10. Continuing to rotate the main body 4 of the light-blocking lens causes the locking rod 12 to press against the limiting protrusions 10, expanding the locking groove 9 until the locking rod 12 can continue to move. After the locking rod 12 passes the limiting protrusions 10, the limiting protrusions 10 lose their pressure, and the locking groove 9 is restored by the material properties of the locking plate 8, thus limiting the locking rod 12 within the space between the limiting protrusions 10 and the end of the locking groove 9, ultimately locking the position of the main body 4 of the light-blocking lens. Figure 6 As shown, by flipping the light-blocking lens body 4, the light-transmitting lens body 1 can be exposed, thereby ensuring the clarity of the person's field of vision;

[0053] When the light is too strong, press down on the light-blocking lens body 4 so that it covers the light-transmitting lens body 1. Figure 1 As shown, this is done by blocking part of the light through the main body 4 of the light-blocking lens.
