Abstract

The utility model relates to a remote controller that includes a shell, an infrared light transmitting tube placed inside the shell and a controlling circuit board. The shell includes an upper cover and a bottom shell. The upper cover provides with some installation holes used for holding various functional keys. The functional keys are made of hard materials. The controlling circuit board includes two parts that are mutually connected. One part is a printing circuit board. The infrared light transmitting tube and the control chip are welded on the printing circuit board. The other part is a pellicle circuit element. The pellicle circuit element is arranged under the various functional keys. Compared with the prior art, the utility model remote controller has the advantages of thinness, low cost and long service life.

Description

Telepilot

Technical field the utility model relates to electrical communication technology, particularly relates to being used for for example telepilot of televisor, DVD player etc. of household electrical appliances.

The telepilot that the background technology prior art is used for various electrical equipment comprises shell, is installed in each function button and setting control circuit board in the enclosure on the shell, described each function button generally by soft material for example silica gel make, this silica gel lower end is an electric conductor, described control circuit board is generally printed circuit board (PCB), even be electrically connected and make circuit to form path to send control signal with two electric contacts on the printed circuit board (PCB) by the electric conductor of next its lower end of function button.There are following many deficiencies in such telepilot: at first, printed circuit board (PCB) is thicker, needs bigger space to hold, so the shell of telepilot is corresponding will do greatlyyer, waste material, and cost height and profile are not attractive in appearance; Secondly, the electric conductor of each function button lower end in use, long-term and printed circuit board (PCB) contact friction, impaired easily, cause telepilot sensitivity to reduce and lack serviceable life; Moreover, the described silica gel push-button fabrication and processing complexity that has electric conductor, cost height.

Utility model content the technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part and proposes a kind of thin thickness and cost is low and the telepilot of long service life.

The utility model solve the technical problem can be by realizing by the following technical solutions:

Design, use a kind of telepilot, comprise shell, be placed on infrared light power valve and control circuit board in this shell, described shell comprises loam cake and drain pan again, and described loam cake has the mounting hole that is used to hold each function button; Described each function button is made by hard material, described control circuit board comprises two parts of mutual electrical connection: a part is printed circuit board (PCB), described infrared light power valve and control chip all are welded on this printed circuit board (PCB), another part is a thin film circuit components, and this thin film circuit components places the below of described each function button.

In the utility model, described thin film circuit components comprises the first film circuit, film separator and second thin film circuit from top to bottom; Over against the below of each function button, the described the first film circuit and second thin film circuit all are printed with the electric contact in order to the control circuit break-make, and in this position respectively, offer through hole on the described film separator.

In the utility model, lay a pot shape shell fragment between each electric contact on described each function button lower end and the first film circuit.

Compare with prior art, the technique effect of the utility model telepilot is: 1. control of remote controller circuit board major part adopts thin film circuit, can dwindle required accommodation space in the telepilot shell effectively, save the material of making shell, reduce the cost of manufacture of telepilot; 2. because control circuit adopts thin film circuit, flexible good and flexible, so the shell of telepilot can as required or be liked and be designed to multiple shape, be not limited to the board-type of prior art, for example can be designed to similar S type, folded form or the like; 3. the function button lower end of telepilot need not possess conducting function, causes the problem that telepilot is malfunctioning and serviceable life is short after having avoided the function button lower end current-carrying part of prior art telepilot impaired; 4. a pot shape shell fragment is set, the sensitivity that has improved telepilot more, and, when using a teleswitch, press function button and can produce " click clatter " sound, can give the prompting of operator with " button puts in place ", make people's sensory effect fine.

Description of drawings

Fig. 1 is the decomposition texture principle schematic of the utility model telepilot.

Embodiment is described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.

The utility model telepilot as shown in Figure 1, comprises shell, is placed on infrared light power valve 70 and control circuit board in this shell, and described shell comprises loam cake 10 and drain pan 20 again, and described loam cake 10 has the mounting hole 11 that is used to hold each function button 30; Described each function button 30 is made by hard material, described control circuit board comprises two parts of mutual electrical connection: a part is printed circuit board (PCB) 50, described infrared light power valve 70 and control chip 60 all are welded on this printed circuit board (PCB) 50, another part is a thin film circuit components, and this thin film circuit components places the below of described each function button 30; Described thin film circuit components comprises the first film circuit 41, film separator 42 and second thin film circuit 43 from top to bottom; Over against the below of each function button 30, the described the first film circuit 41 and second thin film circuit 43 are printed with the electric contact 411,431 in order to the control circuit break-make respectively, and in this position respectively, offer through hole 421 on the described film separator 42.Lay a pot shape shell fragment 80 between each electric contact on described each function button 30 lower end and the first film circuit 41.

In the utility model, described thin film circuit components adopts the thin film circuit components that has been widely used in fields such as computer keyboard, bank cashier switch dish.Described pot shape shell fragment 80 also is the prior art matured product, it has been widely used in the button below of mobile phone, the main effect of pot shape shell fragment 80 has two: one, when described each function button 30 is pressed, this pot shape shell fragment 80 pressurizeds are deformed into recessed down by raising up shown in Fig. 1, make the circuit contacts point 411 and the 431 energy excellent contact of the circuit contacts point on second film circuit board 43 of the corresponding the first film circuit board 41 in its below, thereby make circuit turn-on; The 2nd, pot shape shell fragment 80 can produce sound when compressive deformation, thus the prompting of putting in place for the operator with button, and strengthen operating handle.

During use, the operator is as required by next function button 30, because this function button 30 is made by hard material, it can make the pot shape shell fragment 80 of its below be deformed into recessed down by raising up, make the electric contact 411 of the first film circuit 41 see through through hole 421 on the film clapboard 42 and contact with electric contact 43 on second film circuit board 43 and realize the circuit connection, telepilot sends remote signal; Unclamp this function button 30, the young shell fragment 80 of pot of its below resets, and the electric contact 411 of the first film circuit 41 separates with electric contact 431 on second thin film circuit 43, and circuit disconnects immediately, waits the operator and selects another function button operation.
