Technical Field
[0001] This application relates to the field of optical technology, specifically to a lens, a vehicle lamp, and a corresponding vehicle. Background Technology
[0002] Most current car interior lights require mechanical switches for control. However, in order to meet diverse styling needs and save space, it is often necessary to eliminate the mechanical switch component.
[0003] Application content
[0004] In view of this, one of the problems addressed by an embodiment of this application is to implement touch operation of vehicle lights.
[0005] According to one aspect of this application, a lens is provided, characterized in that the lens comprises:
[0006] - A lens portion for transmitting a light beam, and said lens portion includes a touch area; and
[0007] - Antenna portion, which is conductive and is at least partially opposite the touch area.
[0008] According to an embodiment of this application, when the touch area is touched, the capacitance value of the capacitor formed by the antenna section will change.
[0009] In some embodiments, the antenna portion includes an annular structure, and the central through-hole of the annular structure is used to transmit the light beam to the lens portion.
[0010] In some embodiments, the antenna portion further includes a flange portion formed around the central through-hole and extending from the surface of the annular structure toward the side away from the lens portion.
[0011] According to an embodiment of this application, the flange portion can improve the touch sensitivity of the portion of the touch area opposite to the central through hole, and make the touch sensitivity of the entire touch area more consistent.
[0012] In some embodiments, the flange portion is a continuous wall structure or a discontinuous wall structure surrounding the central through hole.
[0013] In some embodiments, the annular structure has an arcuate surface.

[0037] Preferred embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.
[0038] An embodiment of this application discloses a lens, a corresponding vehicle lamp, and a vehicle.
[0039] According to a vehicle light of this embodiment, reference is made to... Figures 1 to 5 The vehicle headlight according to this application includes a lens P1, a sensor 300, a control unit (not shown), and a light source 510.
[0040] The lens P1 includes a lens portion 100 and an antenna portion 200. The lens portion 100 transmits a light beam and includes a touch area 110. The antenna portion 200 is conductive and at least partially opposite the touch area 110. When a user touches the touch area 110, the capacitance value of the capacitor formed by the antenna portion 200 changes. The sensing unit 300 provides an electrical connection between the antenna portion 200 and the control unit. The control unit senses the change in the capacitance value of the capacitor formed by the antenna portion 200 and controls the illumination of the light source 520 based on this change.
[0041] In one example, the lens portion 100 may be made of a light-transmitting material, such as, but not limited to, transparent glass, resin, or plastic materials, such as transparent PC (Polycarbonate), PMMA (polymethylmethacrylate), etc. Additionally, as... Figure 2 As shown, the lens portion 100 may also include a support portion 120 that is integral with the touch area 110.
[0042] In one example, the antenna part 200 can be a metal part or a non-metal part, but it is covered with a conductive layer, such as, but not limited to, an electroplated layer, a conductive ink layer, etc.
[0043] In one example, such as Figure 4 As shown, the antenna section 200 may include a ring structure 230, the central through-hole 240 of which is used to transmit a light beam to the lens section 100. Preferably, the ring structure 230 may be a sheet structure.
[0044] In addition, such as Figure 5 As shown, the annular structure 230 may have an arcuate surface adapted to the lens portion 100, so that the distance between the annular structure 230 and the lens portion 100 can be kept consistent, thereby ensuring that the sensitivity of the touch area 110 opposite to the annular structure 230 remains consistent.
[0045] In one example, the antenna portion 200 may further include a flange portion 210 formed around the central through-hole 240 of the annular structure 230 and extending from the surface of the annular structure 230 toward the side away from the lens portion 100. For example, as Figure 4 and Figure 5 As shown, the flange portion 210 is a continuous wall structure surrounding the central through hole 240. However, it is understood that the flange portion 210 can also be a discontinuous wall structure surrounding the central through hole 240. Due to the presence of the central through hole 240, the touch sensitivity of the portion of the touch area 110 opposite to the central through hole will be relatively low. However, the flange portion 210 can increase the relative area between the antenna portion 200 and the central portion of the touch area 110, thereby improving the touch sensitivity of this portion and making the touch sensitivity of the entire touch area 110 more consistent.
[0046] In addition, the flange 210 and the annular structure 230 can be a single piece.
[0047] In one example, the lens portion 100 and the antenna portion 200 can be a single piece, for example, but not limited to, formed using an overmolding process. In this case, such as Figure 4As shown, the antenna section 200 also includes a plurality of openings 220 provided on the annular structure 230 for fixing the lens section 100 and the antenna section 200 during the injection molding process. Figure 4 As shown, the plurality of openings 220 can be in the form of small holes, grooves, or a combination of both. Preferably, the plurality of openings are evenly distributed on the flange portion 210.
[0048] By using an overlapping injection molding method, a single piece of touch-sensing material can be formed, reducing the installation structure and steps required to mount the antenna to the lens. At the same time, it can avoid air gaps between the antenna and the lens, thereby improving touch sensitivity and reliability.
[0049] In one example, the sensing unit 300 can be any elastic structure capable of conducting current signals, such as, but not limited to, an elastic reed, a helical spring, etc.
[0050] In one example, the vehicle light also includes a PCBA (Printed Circuit Board Assembly) 500, on which the aforementioned control unit and light source 510 are both disposed.
[0051] In addition, the control unit can control the on / off state of the light source 510 according to predetermined control logic. For example, but not limited to, when the user touches the touch area 110 for the first time, the control unit senses the change in the capacitance value of the capacitor formed by the antenna section 200 and turns on the light source 510. When the user touches the touch area 110 for the second time, the control unit turns off the light source 510. Or, for example, when the user touches the touch area 110 for the first time, the control unit turns on the first level of the light source 510. When the user touches the touch area 110 for the second time, the control unit turns on the second level of the light source 510. When the user touches the touch area 110 for the third time, the control unit turns on the third level of the light source 510. When the user touches the touch area 110 for the fourth time, the control unit turns off the light source 510.
[0052] In one example, such as Figure 1 As shown, the vehicle lamp may also include a light shield 800, a chrome-plated part 700, and a housing 600. Depending on the optical requirements corresponding to the vehicle lamp, the vehicle lamp may also have an inner lens 400, and the sensing part 300 can pass through the inner lens 400 and be connected to the PCB board 500.
[0053] It should be noted that lens P1 is not limited to the above-mentioned vehicle lights; it can also be used in any other suitable lighting or signal indication device.
[0054] This application has the following advantages: it provides a lens with an antenna section, and when the touch area is touched, the capacitance value of the capacitor formed by the antenna section changes; it also provides a touch-controlled vehicle light implemented using the above-mentioned lens, which is more compact in structure, can adapt to more styling requirements, and has relatively consistent touch sensitivity in the touch area.
[0055] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be embraced within this application. No reference numerals in the claims should be construed as limiting the scope of the claims. Furthermore, it is clear that the word "comprising" does not exclude other units or steps, and the singular does not exclude the plural. Multiple units or devices recited in the system claims may also be implemented by a single unit or device in software or hardware. The terms "first," "second," etc., are used to indicate names and do not indicate any particular order.
