Abstract

The utility model relates to an adjustable windscreen wiper controller, composed of a casing, an outer connected plug connected with a power line, an outer connected socket connected with a wiper motor and a peripheral potentiometer extracted from a control circuit. The inner of the casing is provided with an intermittent control circuit completed by a 555 circuit. The utility model has the advantages of simple structure and small size. The utility model can be conveniently arranged in a light motor vehicle on the basis of the original vehicle. The wiper can not only work intermittently but also adjust the working intermittent ratio according to the rainfall amount (The wiper can work one time at least and can work continuously at most within a period of about 12 seconds.).

Description

Adjustable wiper controller

The utility model belongs to the wiper controller, particularly a kind of adjustable wiper controller.

Present vehicle wiper, in light rain or greasy weather, slight snow is when travelling in the weather, continuously scrape as wiper, micro-moisture on the front windshield glass and dirt ash will form a surface of being clamminess so, not only glass can not scraped totally, instead can make glass smudgy, stay stain, influence pilot's line of vision, therefore, senior advanced automobile all is that wiper has been set up batch system (Windshield Wiper stops automatically by some cycles and works, and generally scrapes water and once stops 2-12 second) work intermittently than mostly being fixed, and is the special train special use, and general ordinary vehicle type such as mid-get car (Tianjin Dafa, Jilin, Song Hua River) etc. there is not this device, no matter rainfall size wiper has only a kind of mode of operation.

The purpose of this utility model provides a kind of adjustable wiper controller, on the basis of not destroying former car circuit, be installed in the above-mentioned vehicle very easily, make the wiper not only can intermittent use, also can be according to rainfall size adjusting work intermittently than (12 seconds left and right sides in the cycle minimum work once to the highest continuous working).Overcome the above-mentioned shortcoming and defect of existing product.

The purpose of this utility model is achieved in that

A kind of adjustable wiper controller is characterized in that: by shell, connect external plug to power lead, connect the peripheral hardware potential device of drawing to the external socket of scraping hydroelectric machine and control circuit and form, be the intermittent control circuit of being finished by 555 circuit in the shell.

Control circuit is to connect electricity group R1 from the anodal Y1 end of the power lead of external plug, 555 4,8 pin and the cathode power supply line Z1 of external socket end; The electricity group R1 other end connects diode D1, D2 and 555 7 pin; Diode D1 other end serial connection electricity group R2 and external current potential W1 two ends connect the D2 other end again; The middle slide head connection capacitor C 1 of current potential W1 and 555 6,2 ends; The other end of capacitor C 1 connects the negative pole Y3 end of external plug power lead; 555 5 foot meridian capacitor C2 connect the negative pole Y3 end of external plug power lead; 555 1 pin connects external plug power lead negative pole Y3 end; 555 3 pin connect diode D3 and relay K, the negative pole Y3 end of another termination external plug power lead of diode D3 and relay K; Relay tip 1 connects the Z2 end of external socket, and relay tip 2 connects the negative pole Y3 end of external plug power lead; Relay movable contact 3 connects the Z3 end of capacitor C 3 and external socket, and the other end of capacitor C 3 connects the power lead negative pole Y3 end of external plug.

The utility model has the advantages that:

Simple in structure, volume is little, on the basis of not destroying former car circuit, be installed in the Light-duty Vehicle very easily, make the wiper not only can intermittent use, also can be according to rainfall size adjusting work intermittently than (12 seconds left and right sides in the cycle minimum work once to the highest continuous working).

Below in conjunction with description of drawings embodiment:

Fig. 1 is adjustable wiper controller scheme drawing

Fig. 2 is adjustable wiper controller circuit diagram

This controller is to utilize 555 circuit to finish principle such as Fig. 2 of control.

A kind of adjustable wiper controller by shell 1, connect external plug (B1) 2 to power lead, connect the peripheral hardware potential device 4 (W1) of drawing to the external socket 3 of scraping hydroelectric machine and control circuit and form, is the intermittent control circuit of being finished by 555 circuit in the shell.

Introduction no longer explanation is here all arranged in a lot of books of the service condition of 555 circuit, relay work is controlled by 555 oscillating circuits, the 1. 2. closed rain shaving electrical machine energising work of open contact when the relay adhesive, normally closed contact is 2. 3. closed when relay discharges finishes self-return and regenerative brake provides necessary condition to adjust the position of potential device for rain shaving electrical machine, the dutycycle that can change 555 oscillation periods that is to say adjusted wiper work intermittently than, potential device is as being transferred to right-hand member dutycycle maximum, the continuous working of the normal phase adhesive of relay rain shaving electrical machine, when potential device is transferred to left end dutycycle minimum, so but an of short duration adhesive is arranged owing to be provided with resistance R 2 relays in the circuit, motor has an of short duration galvanization, effect because of self-return circuit in the motor, so wiper only scrapes once, the data oscillation period of diagram circuit component is about 12 seconds, adjusts potential device windscreen wiper is scraped in the cycle once, secondary, three times ... to continuous.

Controller external form such as Fig. 1 controller housing are made by the APS material, and the bodily form is small and exquisite, and housing is connected (can extending and shorten as needs) to connecting between current potential and the housing with 10cm 0.75mm flexible cord between the input and output plugs and sockets by 70cm three core flexible cords.

This controller install very simple existing be example with big sending out, as long as former car rain shaving electrical machine plug and socket is disconnected, it is inserted in respectively again potential device is installed in three rooms of bench board on the plug, socket of controller and gets final product on one of them.Open former car wiper switch during use, according to the big minor adjustment position potentiometer of rainfall, just Windshield Wiper can be transferred to the required optimum Working of individual, used controller not only to increase traveling comfort and driving safety, also prolonged the service life of Windshield Wiper, as long as in other vehicle, install and use corresponding plugs and sockets instead, potential device can be installed on any room of bench board, if any the vehicle wiper be provided with speed retaining and controller control wherein one can be blocked, (preferably control keeps off slowly because fast retaining is to establish for heavy rain, so intermittent use is nonsensical, and control keeps off slowly, could embody its preceence during work).

Controller through I on the Tianjin Dafa car 1 year on probation respond well, the often switch wiper switch that in light rain, travels, very convenient.
