Embodiment Construction

[0022] The following will further describe in detail the technical solution of the vehicle interior light switch control device proposed in one aspect of the present invention with reference to the accompanying drawings and embodiments.

[0023] see figure 1 As shown, in one embodiment of the present invention, the interior light switch control device includes a functional schematic panel 10 , a capacitive sensing circuit 12 , a functional circuit board 14 and a base 18 . The functional circuit board 14 is disposed between the functional schematic panel 10 and the base 18 to form a complete structural device. The function schematic panel 10 is provided with relevant icons and indicator lights, such as one or more buttons and one or more two-color LED lights.

[0024] Wherein, the capacitance sensing circuit 12 is used to sense the capacitance change in front of it, which may be caused by the operator's gesture change, for example, swiping from left to right or swiping from to...

Abstract

The invention discloses an in-vehicle light on-off control device which comprises a capacitance sensing circuit and a functional circuit board, wherein the capacitance sensing circuit is used for sensing a change in capacitance ahead, comparing a waveform generated by the sensed capacitance change with a preset waveform, and transmitting a signal for turning on or off the light to the functional circuit board if the two waveforms match each other. The functional circuit board controls a circuit of the in-vehicle light, and turns on or off the in-vehicle light based on the signal transmitted from the capacitance sensing circuit. The in-vehicle light on-off control device uses a noncontact on-off control mode to conveniently turn on or off the in-vehicle light. There is no need for an operator to divert the attention to operate the in-vehicle light.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a vehicle interior lamp switch control device. Background technique [0002] With the continuous advancement of electronic technology, there are more and more electronic devices on the vehicle, bringing more and more functions of on-board electronic appliances to the vehicle. However, there has been no relevant improvement for the lighting function in the car for a long time. The existing car interior lighting has always been in the form of a mechanical push switch, and the lights in the car are turned on and off by pressing the switch. more convenient. [0003] However, since the operation of the push switch requires the operation of the switch at a specific position, the operator's eyes need to pay attention to the position of the switch within a certain period of time during the operation, and then perform the push operation. This kind of operation is not a problem in ...
