Lens, vehicle lamp and corresponding vehicle

Abstract

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 (P 1 ), characterized in that the lens (P 1 ) comprises:
 a lens part ( 100 ) for transmitting a light beam, the lens part ( 100 ) comprising a touch region ( 110 ); and   an antenna part ( 200 ), the antenna part ( 200 ) being electrically conductive and being at least partially opposite the touch region ( 110 ).   
     
     
         2 . The lens (P 1 ) as claimed in  claim 1 , characterized in that the antenna part ( 200 ) comprises an annular structure ( 230 ), and a central through-hole ( 240 ) of the annular structure ( 230 ) is configured to transmit the light beam toward the lens part ( 100 ). 
     
     
         3 . The lens (P 1 ) as claimed in  claim 2 , characterized in that the antenna part ( 200 ) further comprises a flange part ( 210 ), the flange part ( 210 ) being formed around the central through-hole ( 240 ), and extending from a surface ( 230 ) of the annular structure toward a side remote from the lens part ( 100 ). 
     
     
         4 . The lens (P 1 ) as claimed in  claim 3 , characterized in that the flange part ( 210 ) is a continuous wall-like structure or intermittent wall-like structure surrounding the central through-hole. 
     
     
         5 . The lens (P 1 ) as claimed in  claim 2 , characterized in that the annular structure ( 230 ) has an arc-shaped surface. 
     
     
         6 . The lens (P 1 ) as claimed in any one of  claims 1 - 5 , characterized in that the antenna part ( 200 ) and the lens part ( 100 ) are integrally formed by an overmolding process. 
     
     
         7 . The lens (P 1 ) as claimed in  claim 6 , characterized in that the antenna part ( 200 ) further comprises multiple openings ( 220 ) arranged on the annular structure ( 230 ). 
     
     
         8 . The lens (P 1 ) as claimed in  claim 7 , characterized in that the multiple openings ( 220 ) comprise a small hole and/or a groove. 
     
     
         9 . A vehicle lamp, characterized in that the vehicle lamp comprises the lens (P 1 ) as claimed in any one of  claims 1 - 8 , and the vehicle lamp further comprises a sensing part ( 300 ), a control part and a light source ( 510 ), wherein:
 the sensing part ( 300 ) is configured to provide an electrical connection between the antenna part ( 200 ) and the control part;   the control part is configured to perceive a change in a capacitance value of a capacitor formed by the antenna part ( 200 ), and control the on/off of the light source ( 510 ) according to the change.   
     
     
         10 . The vehicle lamp as claimed in  claim 9 , characterized in that the change occurs in the capacitance value of the capacitor formed by the antenna part ( 200 ) when the touch region ( 110 ) is touched. 
     
     
         11 . The vehicle lamp as claimed in  claim 9 , characterized in that the sensing part ( 300 ) may be either of the following structures:
 an elastic reed;   a coil spring.   
     
     
         12 . The vehicle lamp as claimed in any one of  claims 9 - 11 , characterized in that the vehicle lamp is an in-vehicle reading lamp. 
     
     
         13 . A vehicle, comprising the vehicle lamp as claimed in any one of  claims 9 - 12 .
