Abstract

The utility model relates to an automatic flasher for a motor vehicle, which is mainly characterized in that an inductance element L is connected in series in a circuit at the front end of a metal connector having an insertion opening of a shell body connected with an externally connected reversing switch, and an external connected resistive load is added with small inductive load. When a signal lamp and the circuit have short circuit and earth contact and the positive and the negative poles of a power supply are connected incorrectly, an inductance signal can feed back, and thus the work of an integrated circuit is influenced. A driver can discover problems in time to eliminate faults, therefore, the automatic flasher for a motor vehicle is favorable for safe driving. The utility model can be widely used for controlling the flashing of motor vehicles.

Description

Self-propelled vehicle fool Der Blink und Abblendschalter

The utility model relates to a kind of Der Blink und Abblendschalter of power actuated vehicle controlling party to the indication field, relates in particular to a kind of self-propelled vehicle fool Der Blink und Abblendschalter.

Power actuated vehicle need be represented the service direction of oneself by the lamp on the vehicle body in operational process, these lamps are controlled by Der Blink und Abblendschalter.The misconnection of short circuit, ground connection and the Der Blink und Abblendschalter positive-negative power that causes owing to reasons such as lamp socket, circuits; the capital causes the damage of Der Blink und Abblendschalter or the fusing of wire fuse; influence traffic safety; the electronic flasher that at present comparatively advanced employing UAA1041B integrated circuit and peripheral circuit thereof constitute is being short-circuited or the delay protection in 4 seconds is being arranged during fault such as ground connection.But find that in actual use this delay protection has little significance, navigating mate also had little time reaction in the kind at 4 seconds.

The purpose of this utility model is the deficiency at above-mentioned existence; provide a kind of and when phenomenons such as power positive cathode misconnection, short circuit or ground connection take place, can effectively protect the self-propelled vehicle fool Der Blink und Abblendschalter that self is not damaged; thereby in time remind the navigating mate trouble-shooting, guarantee traffic safety.

The purpose of this utility model is achieved through the following technical solutions: a kind of housing that comprises, integrated circuit (UAA1041B) and relay J (or semiconductor components and devices) in the housing, resistance R 1～R4, the peripheral circuit that capacitor C 1～C2 forms and water the solid self-propelled vehicle fool Der Blink und Abblendschalter that constitutes at the metal connector at housing plug receptacle place is characterized in that tandem electric inductance element L in the circuit of housing plug receptacle and external change-over swith bonded assembly metal connector front end; Adopt relay J in the peripheral circuit on the integrated road (UAA1041B) in the housing, a termination metal connector of inductance component L, another termination integrated circuit (UAA1041B) the 8th pin resistance R 1 and the normal point of connection of making war of relay J; Adopt semiconductor components and devices, a termination metal connector of inductance component L in the peripheral circuit of the integrated circuit (UAA1041B) in the housing; The point of connection of another termination integrated circuit (UAA1041B) the 8th pin resistance R 1 and semiconductor components and devices mouth.

The utility model is by tandem electric inductance element in circuit; make external resistive loading add little inductive load; when short circuit, ground connection appear in signal lamp and circuit; during the power positive cathode misconnection; the inductance signal feedback; integrated circuit is discerned automatically; and the control relay contact discharges; or the control semiconductor components and devices is in by mode of operation; the indication of the direction of operator's compartment does not show and some fault occurred; the prompting chaufeur is got rid of, thereby helps traffic safety, has also protected Der Blink und Abblendschalter self not impaired.The utility model is widely used in self-propelled vehicle flash of light indication control, has good economic benefits and social benefit.

Accompanying drawing is electrical schematic diagram and the external load circuit diagram of the utility model circuit when adopting relay, and the outer circuit of empty frame is external load and working power circuit.

In the accompanying drawing: IC, resistance R 1～R4, capacitor C 1～C2, relay J, inductance component L, change-over swith K, working power E.

Further specify the utility model in conjunction with the accompanying drawings and embodiments, present embodiment just as shown in drawings, in the peripheral circuit of IC, adopt relay J, the peripheral circuit of IC (UAA1041B) is by resistance R 1～R4, capacitor C 1～C2, relay J constitutes, at the front end tandem electric inductance element L of the housing plug receptacle metal connector of external change-over swith K, and the point of connection of the other end connecting resistance R1 of inductance component L and relay J normal battle.After connecting working power E and load, get final product work.
