Description
Technical field
The present invention relates to automobile equipment technical field, be specially a kind of car wiper with delay function.
Background technology
Rain brush is mounted in the important accessory on air regulator, and its effect is sleet and dust that cleaning front windshield glass is obstructed the view.Therefore, it has important effect for traffic safety.
Rain brush in the market roughly can be divided into two kinds, and a kind of is traditional batch (-type) rain brush, and this is also use maximum one now, and the sight line that rain brush speed can be driven according to rainfall impact divides the adjustment of three to level Four; Another kind is the raindrop induction type rain brush be used in recent years in middle-and-high-ranking vehicle more, and rain brush can be regulated the speed automatically according to rainfall.
No matter be traditional batch (-type) rain brush or the rain brush of automatically regulating the speed according to rainfall, rain brush be all with automobile before carry sprinkler work carry out simultaneously, but after automobile fine day is parked, dust etc. are bonded on glass and wiper, make glass smudgy, if the relay with delay function can be arranged on the drive motor of rain brush, at water spray after 0.5 ~ 2 second, rain brush cleans again, just can realize cleaning performance more, rain brush also and then can not be obstructed and cause drive motor impaired because of the viscosity of dust.
Summary of the invention
The object of the present invention is to provide a kind of car wiper with delay function, it is provided with time delay circuit on the drive motor of automobile wiper, and then reaches rain brush work and can not be obstructed, and cleaning effect is better.
For achieving the above object, the invention provides following technical scheme: a kind of car wiper with delay function, comprise Wiper motor, rain brush support link and windshield wiper frame; Described Wiper motor is provided with slug relay, and its time delay circuit comprises resistance R1, resistance R2, resistance R3, electric capacity C1, diode D1 and field effect transistor T1; Described resistance R1, diode D1, the first electric capacity C1, resistance R3 form the differential circuit of time delay circuit after connecting successively; The switch circuit of described field effect transistor T1 and resistance R1 series connection time delay circuit; Described resistance R2 connects as the discharge circuit of time delay circuit with electric capacity C1.
Further, described Wiper motor output revolving shaft connecting windscreen wiper support link, described windshield wiper frame is connected with rain brush support link.
Further, on described windshield wiper frame, bottom is provided with and blows rain adhesive tape; Describedly blow the elastomeric material that rain adhesive tape is preferably Wear-resistant, high-temperature resistant.
Further, described resistance R3 and field effect transistor T1 is electrically connected rear ground connection.
Compared with prior art, the invention has the beneficial effects as follows: this Novel windscreen wiper, Wiper motor is provided with slug relay, in use, first be water pump pump water feed pipe, carry out the moistening of the Windshield of automobile, after the water spray effect after Preset Time is 0.5 ~ 2 second, and then conveniently scrubbing of rain brush can be realized, and can not scrub unholiness because of staiing too much and then cause rain brush or cause more greatly the damage of rain brush due to friction; Unit design is rational in infrastructure, easy to use, first within 0.5 to 2 seconds, allows after water spray be bonded on glass and wiper start windscreen wiper after dust dissolving, protects windscreen wiper like this and reaches better cleaning performance, very practical.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1-2, the invention provides a kind of technical scheme: a kind of car wiper with delay function, comprise Wiper motor 1, rain brush support link 2 and windshield wiper frame 3; Described Wiper motor 1 is provided with slug relay 11, and its time delay circuit comprises resistance R1, resistance R2, resistance R3, electric capacity C1, diode D1 and field effect transistor T1; Described resistance R1, diode D1, the first electric capacity C1, resistance R3 form the differential circuit of time delay circuit after connecting successively; The switch circuit of described field effect transistor T1 and resistance R1 series connection time delay circuit; Described resistance R2 connects with electric capacity C1 as the discharge circuit of time delay circuit; Resistance R1, diode D1, the first electric capacity C1, resistance R3 form the differential circuit of time delay circuit after connecting successively, for generation of switch circuit gate drive signal, R1, T1 form switch circuit, for generation of input queued switches pulse delay, R2 forms discharge circuit, reset for electric capacity, ensure the normal generation of input queued switches impulse singla time delay of next cycle.
When input queued switches impulse singla positive rise arrives, signal charges to electric capacity C1 through R1, D1, R3, resistance R3 produces an impulse singla, namely the gate drive signal needed for fet switching circuit pipe T1, and then field effect transistor T1 is through R1 conducting, make output be low level, thus input queued switches impulse singla was lost efficacy.T1 ON time is the delay time that time delay circuit produces.After T1 conducting terminates, input queued switches impulse singla directly exports through the R1 of time delay circuit.When the falling edge of input queued switches impulse singla arrives, the R2 in discharge circuit then gives the electric discharge of the C1 in differential circuit, makes it reset, normally to produce required time delay in the next cycle.The parameter value of suitable selection R1, R3, C1 can change the time of time delay.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification sheets is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of specification sheets is only for clarity sake, those skilled in the art should by specification sheets integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
