In the indoor dome lamp of car, the transparent lamp shade of diamond effect is because pleasing to the eye degree is good and the wide application, and along with touch switch's application brings better and better use experience for the customer, also by the wide application in the car boundary. How to use touch switch on transparent lamp shade, and do not influence the whole effect of transparent lamp shade, be the technical problem that needs to solve at present urgently. Because touch switch has touch structure, still is provided with corresponding response structure on the circuit board, touch structure may influence transparent lamp shade's transparency, simultaneously, sees through transparent lamp shade and sees the response structure of the inside, can influence transparent lamp shade's result of use equally, makes transparent lamp shade look unclean, has the foreign matter sensation.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a touch switch structure suitable for transparent lampshade solves current transparent lampshade and sets up the problem that touch structure influences transparent lampshade's result of use.

The utility model provides a technical scheme that its technical problem adopted is: a touch switch structure suitable for a transparent lampshade comprises a shell, the transparent lampshade arranged on the shell and a reflecting bowl positioned below the transparent lampshade; the shell is also provided with a rear cover, a circuit board arranged on the rear cover and a light emitting source arranged on the circuit board in a clamping manner; one deck metal chromium has been plated on the top layer of reflector, reflector's top and transparent lampshade contact cooperation, reflector's below is provided with the extension piece that extends to the transparent lampshade outside, the below of extending the piece is provided with conductive rubber, be provided with electric capacity response chip on the circuit board, conductive rubber and electric capacity response chip circuit connection.

In order to improve the sensitivity of touch induction, the thickness of the transparent lampshade is not more than 3mm.

In order to ensure the reliability of contact, a conductive spring is arranged between the conductive rubber and the circuit board.

Furthermore, in order to improve the contact reliability and prolong the service life, a metal conducting strip is arranged on the circuit board, a conducting spring mounting hole is formed in the conducting rubber, one end of the conducting spring is installed in the conducting spring mounting hole, and the other end of the conducting spring is pressed on the metal conducting strip.

The utility model has the advantages that: the utility model discloses a plate one deck metallic chromium on the top layer of reflector, guarantee the hi-lite requirement of reflector promptly, can play fine electric conductive property again. Then extend the bottom of reflector to transparent lamp shade's the outside to set up conductive rubber and circuit board cooperation in the below of extending the piece, thereby realize the touch function, this structure is fine realization touch control's function under the prerequisite that does not influence transparent lamp shade and light the effect. And the position of the extension piece can be adjusted according to the space of an actual switch, so that the limited space is reasonably utilized, and the arrangement is convenient. The transparent lampshade is made of non-conductive plastic or glass, and the thickness of the transparent lampshade is smaller than 3mm in order to improve the sensitivity of touch sensing. The conductive spring can play a good supporting role, and the conductive rubber is prevented from deforming to cause contact matching failure with a circuit board and influence the sensitivity of the switch. Meanwhile, the metal conducting plate is additionally arranged on the circuit board, a common gold-plated disc structure on the circuit board is not adopted, the gold-plated disc structure is easy to oxidize, touch failure is caused, and the contact stability of the metal conducting plate is better, so that the service life of the switch can be effectively prolonged.

The present invention will be described in more detail with reference to the accompanying drawings and examples.

Detailed Description

An embodiment, as shown in fig. 1, is a touch switch structure suitable for a transparent lampshade, which solves the problem that the lighting effect of the transparent lampshade is affected by the adoption of a touch structure of the transparent lampshade. The switch structure comprises a shell 1, a transparent lampshade 2 arranged on the shell 1, a reflecting bowl 3 positioned below the transparent lampshade 2, and a light guide column 11 arranged below the reflecting bowl 3. Still the joint is provided with back lid 4 on the casing 1, install circuit board 5 on the back lid 4, be provided with light emitting source 6 on the circuit board 5, light emitting source 6 is located leaded light post 11 under, preferably adopts the LED light source.

In order to realize the touch control function of the switch and simultaneously not influence the use effect of the original transparent lampshade, the transparent lampshade 2 is made of non-conductive transparent plastic or glass. The surface layer of the reflector 3 is plated with a layer of metal chromium, so that the requirements of high brightness and electric conduction of the reflector are met. The top of reflector 3 and transparent lamp shade 2 contact cooperation, for the sensitivity that improves the capacitance-sensitive, transparent lamp shade 2's thickness is not more than 3mm. An extension piece 31 extending towards the outer side of the transparent lampshade 2 is arranged below the reflecting bowl 3, conductive rubber 7 is arranged below the extension piece 31, a capacitance sensing chip 8 is arranged on the circuit board 5, and the conductive rubber 7 is in circuit connection with the capacitance sensing chip 8; the capacitive sensing chip 8 is also arranged in an area not visible through the transparent cover 2. When the transparent lampshade 2 is touched by a finger, the capacitance sensing chip 8 can detect the capacitance change at the top of the reflecting bowl, so that the light-emitting source 6 is controlled to be switched on and off.

In order to enhance the matching reliability, a conductive spring 9 is arranged between the conductive rubber 7 and the circuit board 5. The clearance generated by operation, assembly and the like is solved through the scalability of the conductive spring 9, so that the reliability of the touch switch is improved. Meanwhile, the metal conducting plate 10 is arranged on the circuit board 5 instead of adopting a gold-plated disc structure, the gold-plated disc structure is easy to oxidize and lose conductivity, the service life of the switch is seriously influenced, the metal conducting plate 10 is simple in structure and not easy to damage, and the service life of the switch can be prolonged.
