Abstract

The utility model relates to a self inspector for braking and steering signals of a vehicle. Electronic components of resistors (3), (4), (6), transistors (5) (7), a relay (8), a buzzer (9), etc. are assembled and connected with a special wiring printed circuit board (12) designed according to the circuit working principle. Binding posts of input and output are connected with the special wiring printed circuit board, and a casing is arranged. The utility model has the advantages of simple structure and easy installation, is suitable for the detection of braking and steering signal lamps of various vehicles. The utility model enables drivers to find the working conditions of the signal lamps outside the car so as to reduce traffic accidents caused by the damage of the braking and steering signal lamps and lighten drivers' labour intensity.

Description

Self inspector for indicator and hazard flasher lights

The utility model relates to a kind of automatic checkout equipment in motor vehicle brake, the turn-signal system.

In motor vehicle brake, turn-signal system, has only braking oil pressure before the utility model, vapour pressure device, not braking, turn sign circuit for lamp automatic checkout equipment.Therefore, chaufeur does not know in driving procedure whether car external signal lamp is excellent, just do not know stop, tail and number plate light, and it is bright whether turn signal lamp has.If chaufeur does not know that signal lamp does not work, the vehicle of trailing just do not know fwd fortune to, thereby traffic accident easily takes place.

The utility model purpose just provides a kind of car brakeing, turn sign automatic detector; Wait the position near being installed in instrument carrier panel below in the operator's compartment or fuse box, as long as braking just detects the integrity of braking, turn signal lamp automatically, and tells chaufeur when turning to work, make chaufeur in time fix its signal lamp, the assurance safety traffic.

Advantage of the present utility model is: (1) makes simple, and is easy for installation, do not influence interior other equipment of operator's compartment and appearance and neatly reach primary circuit, and general those of ordinary skill just can be installed; (2) detection sensitivity height, as long as there is signal lamp bad, detector just can be reported to the police; (3) be applicable to various power actuated vehicles installations.

Invention main points of the present utility model are: mainly be to see the detection resistance R ₁On voltage swing decide BG ₁, BG ₂Mode of operation, as the whole BG just often of signal lamp ₁, BG ₂Work makes actuating of relay contact J _1-1Disconnect, the buzzer phone no-voltage is not reported to the police.BG when an above signal lamp is bad ₁, BG ₂Not working is failure to actuate relay tip, and contact J1-1 connects and reports to the police after buzzer phone gets voltage.

The purpose of this utility model is to realize like this, with resistance (3), (4), (6), aerotron (5), (7), relay (8), buzzer phone (9), input terminal (1), output wiring terminal (2) are all pressed the element numbers welding on the special-purpose wiring printed circuit board (PCB) (12), load onto shell (11) then, at last this automatic detector is connected on the appropriate location in braking, the turn signal lamp circuit system and gets final product.

Concrete structure of the present utility model provides by the following drawings with in implementing.

Fig. 1 is motor vehicle brake, the special-purpose wiring printed board circuit of turn sign automatic detector fundamental diagram, and its principle of work is to flow through resistance R as braking current ₁The time, when promptly braking work, resistance R ₁On voltage raise, make BG ₁(aerotron) is by amplifying by becoming conducting.BG ₁After amplifying, (triode) conducting makes BG ₂The base tension of (triode) raises, BG ₂(triode) conducting soon is saturated, BG ₂Relay on (aerotron) collecting electrode is just worked break J after getting voltage _1-1Disconnect, the buzzer phone no-voltage does not just ring, and proves that stoplight stop lamp is all normal.After an above signal lamp is bad, resistance R ₁Voltage make BG inadequately ₁Enter conducting state BG ₁BG ₂All be in off condition, relay is not worked, break J _1-1Connect, buzzer phone gets voltage and sends chimes of doom later at this moment, proves that brake lamp is bad.The annexation of its element is: the upper end and the aerotron BG that will detect resistance R 1 ₁Emitter, an end of relay coil, relay face contact 1 is connected to positive source Vcc, i.e. the input end U of detector _O, resistance R ₁The lower end simultaneously and resistance R ₂, an end of braking, turn signal lamp is connected.Resistance R ₂The other end be connected aerotron BG with the base stage of aerotron BG1 ₁Collecting electrode and resistance R ₂One end is connected, resistance R ₃The other end and aerotron BG ₂Base stage is connected, aerotron BG ₂Collecting electrode be connected with an end of relay coil.Aerotron BG ₂Emitter after an end of buzzer phone is connected, be connected with power cathode.The other end of buzzer phone is connected with relay tip 2, and the integral body that has so just constituted whole detector connects and work relationship.

Fig. 2 is self-propelled vehicle braking, turn sign automatic detector scheme drawing.(1) is that input meets post U among the figure ₁, (2) are output wiring terminal U _O, (3) are resistance R ₁, (4) are resistance R ₂, (5) are aerotron BG ₁, (6) are resistance R ₃, (7) are aerotron BG ₂, (8) are relays, and (9) are buzzer phones, and (10) are ground terminals, and (11) are shells.(12) be the special-purpose wiring printed circuit board (PCB) that makes by Fig. 1.

In this enforcement with input terminal U ₁(1), output wiring terminal U _O(2), resistance R ₁(3), R ₂(4), R ₃(6), aerotron BG1(7), relay J (8), buzzer phone F(9) is installed on the printed circuit board (PCB) by the braking of Fig. 1 self-propelled vehicle, turn sign automatic detector fundamental diagram, input terminal (1) output wiring terminal (2) is installed again loaded onto shell (11) and get final product.
