The existing touch ceiling lamp structure usually adopts a touch FPC for realizing a touch function, the structure is complex in production process and high in manufacturing cost, the whole ceiling lamp needs to be replaced after the structure is damaged, and the maintenance cost is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an indoor dome lamp touch structure of car solves the problem that current touch dome lamp production technology is complicated, with high costs.
The utility model provides a technical scheme that its technical problem adopted is: a touch structure of an indoor dome lamp of an automobile comprises a dome lamp shell, a refraction bowl, a lampshade and a circuit board, wherein the refraction bowl, the lampshade and the circuit board are arranged in the shell; the lamp shade and the cooperation of refraction bowl contact, the lamp shade adopts non-conducting material preparation, the refraction bowl has electric conductivity, be provided with on the circuit board with refraction bowl contact cooperation response lamp shade on human capacitance change's touch pad, still be provided with the electric capacity response chip of being connected with touch pad electricity on the circuit board.
In order to ensure the reliability of assembly and the reliability of human body capacitance induction, a pressure spring is arranged between the refraction bowl and the touch pad.
For easy to assemble, the side of refraction bowl is provided with the pressure spring erection column, the pressure spring cover is on the pressure spring erection column, and the other end is pressed on the touch pad.
For improving the complex reliability, the top of refraction bowl is provided with the first panel that switches on of round and lamp shade panel contact, the side of refraction bowl still is provided with and switches on the panel with lamp shade installation face bottom complex second.
Preferably, the material of the lampshade is PC 2805.
Preferably, the refraction bowl is a plated part, and the surface of the refraction bowl is plated with a layer of conductive metal chromium.
The utility model has the advantages that: the utility model discloses an adopt lamp shade and refraction bowl cooperation to set up the touch pad on the circuit board, come the change of the human electric capacity of perception, thereby light and close the dome lamp, this simple structure, and be difficult to damage, it is with low costs. Meanwhile, the pressure spring is added to ensure the circuit conductivity of capacitance induction, so that the manufacturing and assembling errors of the refraction bowl are avoided, and a passage cannot be formed between the pressure spring and the touch pad.
The present invention will be described in more detail with reference to the accompanying drawings and examples.

Detailed Description
In the embodiment, as shown in fig. 1 to 3, an automobile indoor ceiling lamp touch structure comprises a ceiling lamp housing 1 and a circuit board 4 arranged in the housing 1, wherein an LED light source 8 is arranged on the circuit board 4. Still be provided with refraction bowl 2 on the casing 1, be provided with in the refraction bowl 2 with LED light source 8 complex crystal 9, be provided with lamp shade 3 in the top of refraction bowl 2, lamp shade 3 and the cooperation of refraction bowl 2 contact. The lampshade 3 is made of a non-conductive material, preferably a PC 2805 material, and can sense the change of the capacitance of a human body. The refraction bowl 2 is a plated part, the surface of the refraction bowl is plated with a layer of conductive metal chromium, the refraction bowl has conductivity, and a gap must be eliminated as close as possible in the fitting process between the refraction bowl 2 and the lampshade 3 so as to reduce the loss of a capacitance conduction process. Be provided with on the circuit board 4 with refraction bowl 2 contact cooperation response lamp shade 3 go up human capacitance variation's touch pad 5, still be provided with the electric capacity response chip 6 of being connected with touch pad 5 electricity on the circuit board 4. Under the condition that the human body does not touch the lampshade 3, the initial state of the capacitance between the lampshade 3 and the touch pad 5 is a constant value, when the human body touches the lampshade 3, the capacitance between the lampshade 3 and the touch pad 5 can be changed, and when the capacitance sensing chip 6 receives a signal of capacitance change, the LED light source 8 can be controlled to be turned on or turned off. The touch ceiling lamp is simple in structure, low in cost, not prone to damage and long in service life.
In order to improve the contact reliability, a pressure spring 7 is arranged between the refraction bowl 2 and the touch pad 5.
