Description
Technical field
The present invention relates to the rain shaving electrical machine control devices and its control method of a kind of vehicle wiper.
Background technique
In the prior art, as shown in figure 9, having gear cam 14, gear 13 on the gear 13 of rain shaving electrical machine control device
Rotation driven gear cam 14 rotates, and can stir different contact reed 12 respectively and deform, so as to determine touching on circuit board
Point and 11 open circuit of movable contact on contact reed 12, are connected to wiper controller for fixed contact and movable contact 11, so as to obtain
The angle that gear 13 rotates, can further obtain the position of windscreen wiper, the prior art haves the shortcomings that as follows, 1, contact reed
12 constantly deformation, service lifes shorten；2, since gear cam 14 is when being switched on or switched off, at least one section movement is in slow
In slow variation, so that movable contact 11 and fixed contact are also at the state being slowly switched on or switched off, this is opened in the contact of electric appliance
The Central Shanxi Plain is the movement avoided greatly, it is known that the switch for being in critical state can make switch generate many noise signals, the noise
Signal can interfere the normal work of chip, to will appear erroneous judgement.
Summary of the invention
The present invention is according to the above deficiency, provide a kind of rain shaving electrical machine control device of vehicle wiper.
The technical scheme is that
A kind of rain shaving electrical machine control device of vehicle wiper, comprising:
Shell；
Rain shaving electrical machine, shell are immobilized in the shell, which can drive windscreen wiper component to blow the rain on automobile front glass；

Return piece is provided with outer lug and interior lug, and the outer lug and interior lug are provided with included angle A；
Reed mounting plate, is immobilized in the shell；
First reed, one end are fixed with reed mounting plate, when metal return piece follows gear to rotate, the first reed it is another
End can contact outer lug；
Second reed, one end are fixed with reed mounting plate, when metal return piece follows gear to rotate, the second reed it is another
End is contacted with metal return piece always；
Third reed, one end are fixed with reed mounting plate, when surely belonging to return piece gear being followed to rotate, the other end of third reed
Lug in capable of contacting；
Wiper controller, electrical connection automobile ECU, the first reed, the second reed, third reed and rain shaving electrical machine, windscreen wiper control
Device is powered by automobile batteries；
It should be noted that the first reed of the invention, the second reed, third reed are contacted with metal return piece always, therefore,
First reed, the second reed, third reed elastic force be it is constant, may be at that contact is good always, the moderate state of elasticity,
To greatly reduce the deformation of reed, extend the service life, in addition, reed from the contact of interior lug and outer lug and disconnection
In the process, therefore the not slowly varying stage is powered very short with the generation time of disturbing pulse in power process, interference
It significantly reduces.
Preferably, the outer lug and interior lug included angle A are 135 degree.
A kind of control method of the rain shaving electrical machine control device of vehicle wiper, includes the following steps:
S1 wiper controller receives the control instruction of automobile ECU, and automobile ECU receives vehicle manual wiper control switch signal；
S2 wiper controller judges whether vehicle manual wiper control switch is opened, if it is,
S3 control rain shaving electrical machine starts to blow rain；
S4 wiper controller judges whether vehicle manual wiper control switch closes, if it is not, then step S3 is executed, if so,
Then
S5 judges whether the first reed is connected to the second reed, if so, windscreen wiper has been in situ, then controls rain shaving electrical machine stopping
Rotation, if it is not, then
S6 control rain shaving electrical machine makes windscreen wiper blow rain outward；
S7 judges whether the second reed is connected to third reed, if it is,
The reversion of S8 rain shaving electrical machine, windscreen wiper blow rain to direction in situ, judge whether the first reed is connected to the second reed, if so,
Then windscreen wiper has been in situ, and control rain shaving electrical machine stops operating, and waits manual wiper control switch signal next time.
In the step S3, when the rain shaving electrical machine starts to blow rain, there are 5 gears, there is different windscreen wiper speed.
The present invention simple, at low cost, easy to process, long service life, the beneficial effect of high reliablity with structure.
