Lens, vehicle lamp and corresponding vehicle
A lens, a vehicle lamp, and a corresponding vehicle, the lens including a lens portion with a touch area and an antenna portion including a flange portion, the antenna portion being electrically conductive and at least partially opposite to the touch area. When the touch area of the lens provided with the antenna portion is touched, the capacitance of a capacitor formed by the antenna portion will change.
1. A lens assembly, comprising:
a lens part for transmitting a light beam, the lens part including a touch region;
an antenna part, wherein the antenna part includes an annular structure and a central through-hole in the annular structure;
the lens part disposed over an inner lens;
the antenna part being electrically conductive and located at least partially opposite the touch region; and
the antenna part configured to mate with an elastic reed that passes through the inner lens.
2. The lens assembly of claim 1 , where the central through-hole is configured to transmit the light beam toward the lens part.
3. The lens assembly of claim 2 , wherein the antenna part includes a flange part, with the flange part being formed around the central through-hole and extending from a surface of the annular structure toward a side remote from the lens part.
4. The lens assembly of claim 3 , wherein the flange part is a continuous wall-like structure or intermittent wall-like structure surrounding the central through-hole.
5. The lens assembly of claim 2 , where the annular structure has an arc-shaped surface.
6. The lens assembly of claim 1 , wherein the antenna part and the lens part are integrally formed by an overmolding process.
7. The lens assembly of claim 2 , wherein the antenna part includes multiple openings arranged on the annular structure.
8. The lens assembly of claim 7 , wherein each of the multiple openings includes a small hole or a groove.
9. The lens assembly of claim 1 , where a light-blocking plate is configured to retain a chrome plate at an interface of the lens part, the interface located at a support part that is integral with the touch region.
10. A vehicle lamp, comprising:
a lens part for transmitting a light beam, the lens part including a touch region;
an antenna part being electrically conductive and located at least partially opposite the touch region;
the lens part disposed over an inner lens;
a sensing part, a control part and a light source, where the sensing part includes a coil spring and the sensing part is configured to pass through the inner lens;
wherein the sensing part is configured to provide an electrical connection between the antenna part and the control part; and
the control part configured to perceive a change in a capacitance value of a capacitor formed by the antenna part and control the on/off of the light source according to the change.
11. The vehicle lamp of claim 10 , wherein the change occurs in the capacitance value of the capacitor formed by the antenna part when the touch region is touched.
12. The vehicle lamp of claim 10 , where a flange part is formed around a central through-hole of an antenna part and extends from a surface of the antenna part toward a side remote from the lens part the flange part being a continuous wall-like structure surrounding the central through-hole.
13. The vehicle lamp of claim 10 , wherein the vehicle lamp is an in-vehicle reading lamp.
14. The vehicle lamp of claim 10 , wherein a light-blocking plate is configured to retain a chrome plate at a support part of the lens part, the support part being integral with the touch region.
15. A lens assembly, comprising:
a lens part for transmitting a light beam, the lens part including a touch region; and
an antenna part, wherein the antenna part includes an annular structure and a central through-hole in the annular structure;
the lens part disposed over an inner lens;
the antenna part being electrically conductive and located at least partially opposite the touch region; and
the antenna part configured to mate with a coil spring that passes through the inner lens.
16. The lens assembly of claim 15 , where the annular structure has an arc-shaped surface.
17. The lens assembly of claim 15 , wherein the antenna part and the lens part are integrally formed by an overmolding process.
18. The lens assembly of claim 15 , wherein the antenna pert includes multiple openings arranged on the annular structure.
19. The lens assembly of claim 18 , wherein each of the multiple openings includes a small bole or a groove.
20. The lens assembly of claim 15 , where a light-blocking plate is configured to retain a chrome plate at a support part of the lens part, the support part being integral with the touch region.
