Abstract
The utility model discloses an automatic windscreen wiper resetting device, comprising a windscreen wiper, a windscreen wiper motor, an igniting switch and a combined windscreen wiper switch. The three ends of the windscreen wiper motor respectively are a low-speed end, a high-speed end and a grounding end. The grounding end is grounded, and a fixed end of the windscreen wiper is a resetting end. An end point in a windscreen wiper arm movable area of the windscreen wiper is grounded, and the other end point is used for connecting with a power supply end of the igniting switch. The igniting switch is connected with a normal power source, and the other end of the normal power source is grounded. Four terminals of the combined windscreen wiper switch are respectively connected with the high-speed end, the low-speed end, the resetting end and the power supply end. The both ends of the igniting switch are connected in parallel with a delay relaying device, and the control end of the delay relaying device is provided with the igniting switch. According to the automatic windscreen wiper resetting device disclosed by the utility model, a windscreen wiper arm further can be ensured to be accurately reset to an original position when power is switched off after an automobile key is pulled out.
Description
Technical field
The utility model relates to the Wiping device of automobile, refers in particular to a kind of windscreen wiper automatic resetting device that can delay time.
Background technology
At sleety weather, for a visual field clearly is provided to chaufeur, guarantee to drive safety, on the front windshield glass of automobile windscreen wiper system is installed, the sleet on the front windshield glass can be eliminated timely.Windscreen wiper system is made up of rain shaving electrical machine, windscreen wiper arm and scraping blade usually, and rain shaving electrical machine utilizes the battery-operated of storage battery, drives the motion of windscreen wiper arm and scraping blade, thereby removes the sleet on the front windshield glass.When removing on the front windshield glass sleet, must guarantee that the windscreen wiper arm can get back to initial bit accurately and reliably.
Extract at car key under the situation of outage, windscreen wiper is stop motion immediately, if windscreen wiper moved and just can not be in the return state this moment, it is attractive in appearance to influence vehicle.After simultaneously windscreen water on glass evaporated in docking process, when vehicle started once more, windscreen wiper self-return once more can be in the dry grinding state, influenced windscreen wiper service life.
The day for announcing is that the patent that October 24, notification number in 2007 are CN200964101Y discloses a kind of Automobile wiper switch; Belong to the RC delay control switch; Comprise switch matrix and circuit card, this plate is provided with intermittently element circuit, windscreen wiper hysteresis/interlock element circuit, driving circuit and protective circuit.Though this utility model has been used time delay circuit, the RC time-delay is still not accurate enough, can not guarantee the complete return of windscreen wiper arm.
The utility model content
In order to solve that existing wiper system windscreen wiper arm after outage stops and the problem that can not reset fully; The utility model provides a kind of windscreen wiper automatic resetting device; In wiper control circuit, increase a time-delay relay system, can also continue after car key is extracted outage to guarantee that the windscreen wiper arm has the time enough self-return.
The technical scheme that the utility model adopted is: a kind of windscreen wiper automatic resetting device; Comprise windscreen wiper, rain shaving electrical machine, ignition lock, Windshield Wiper combined switch, described rain shaving electrical machine three ends are respectively low speed end, speed end and ground terminal, ground terminal ground connection; The fixed end of described windscreen wiper is the return end; An end points ground connection of the windscreen wiper arm activity interval of windscreen wiper, another end points is for connecting the power end of ignition lock, and ignition lock connects normal power supply; Normal power supply other end ground connection; Four terminals of described Windshield Wiper combined switch link to each other with speed end, low speed end, return end and power end respectively, a time-delay of described ignition lock two ends parallel connection relay system, and described time-delay relay system control end is an ignition lock.In wiper control circuit, increase a time-delay relay system; After car key is extracted outage; Can also continue to guarantee that wiper control circuit has the T electric current of second (windscreen wiper is the one-period time back and forth), this state is down no matter windscreen wiper is in the optional position time enough self-return is all arranged.
As preferably, described time-delay relay system is single time relay.When ignition lock is extracted, the time-delay relay system with the current slow T second in the control circuit (windscreen wiper is the one-period time back and forth) after outage again, no matter this moment, windscreen wiper was in the optional position, self-return after continue carrying out a point to scrape stroke.
As preferably, described time-delay relay system is the combination of two or more time relays.Adopt two or more time relays, the time is controlled more accurately.
The beneficial effect of the utility model is: after car key was extracted outage, the utility model can guarantee that the windscreen wiper arm accurately gets back to initial bit.
Description of drawings
Fig. 1 is the schematic circuit diagram of the utility model.
Wherein, 1-windscreen wiper, 2-rain shaving electrical machine, 3-ignition lock, 4-Windshield Wiper combined switch, the 5-relay system of delaying time, the normal power supply of 6-, a-ground terminal, b-power end, c-return end, d-low speed end, e-speed end.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
Embodiment 1
As shown in Figure 1, a kind of windscreen wiper automatic resetting device comprises windscreen wiper 1, rain shaving electrical machine 2, ignition lock 3, Windshield Wiper combined switch 4; Wherein three ends of rain shaving electrical machine 2 are respectively low speed end d, speed end e and ground terminal a; Ground terminal a ground connection, the fixed end of windscreen wiper 1 are return end c, an end points ground connection of the windscreen wiper arm activity interval of windscreen wiper 1; Another end points is for connecting the power end b of ignition lock 3; Ignition lock 3 connects normal power supply 6, normal power supply 6 other end ground connection, and four terminals of Windshield Wiper combined switch 4 link to each other with speed end e, low speed end d, return end c and power end b respectively; The time-delay relay system 5 that the ignition lock two ends single time relay of parallel connection constitutes, the control end of time-delay relay system 5 connects ignition lock 3.
During use, time-delay relay system 5 carries out delay process according to the windscreen wiper one-period time back and forth.When ignition lock is extracted, time-delay relay system 5 with the current slow T second in the control circuit (windscreen wiper is the one-period time back and forth) after outage again, no matter this moment, windscreen wiper was in the optional position, self-return after continue carrying out a point to scrape stroke.
Time-delay relay system 5 among the embodiment 2 is two or more time relays, other with embodiment 1 in identical.
Above embodiment is merely the technological thought of explanation the utility model; Can not limit the protection domain of the utility model with this; Every technological thought that proposes according to the utility model, any change of on the technical scheme basis, being done all falls within the protection domain of the utility model.
