Referring next to Fig. 3, it illustrates the structure diagram of the windscreen wiper system according to the present invention, the structure diagram is understood incorporated by reference to Fig. 2.Windscreen wiper system includes the first lead 31 and the second lead 32, first lead 31 and the second lead 32 are connected to form the path for controlling water jet assembly to spray water with there is the terminal of electrical potential difference respectively, for example the first lead 31 can connect positive pole and the second lead 32 can be grounded, or, second lead 32 can the first lead 31 can be grounded for positive pole, it should be understood that the position of the first lead 31 and the second lead 32, both positive and negative polarity etc. all can be changed or exchanged.The first lead 31 may be connected to normal positive pole in one embodiment and the second lead 32 can be grounded, water jet assembly is (specifically, water pump 3 therein) it is attached in above-mentioned path, for example it is connected on the first lead 31 or the second lead 32 and (is illustrated as being connected on the first lead 31).In one embodiment, water spray switch can control the whole circuit for being used to control water jet assembly by wire to be connected with the first lead 31 or the second lead 32, i.e. when water spray switch is not switched on, although windscreen wiper is moved back and forth, water jet assembly will not periodically spray water.First lead 31 connects the first contact 311 and the second lead 32 connects the second wafer 321.As shown in Figure 2, the first contact 311 is resiliently biased with the second wafer 321 contacts to be remained in the rotary course of contact disc 1 with contact disc 1.When the first contact 311 and the second wafer 321 contact conductive part 12 so that the first lead 31 is connected with the second lead 32 simultaneously, electric current flows through windscreen wiper water pump 3 so that water jet assembly is sprayed water, when at least one of the first contact 311 and the second wafer 321 cause the first lead 31 and the disconnection of the second lead 32 not in contact with conductive part 12, not having electric current to flow through windscreen wiper water pump 3, then water jet assembly will not spray water, it can be seen that the first lead 31 and the second lead 32 constitute the control circuit for controlling water jet assembly to spray water together with contact disc 1.In addition; rain shaving electrical machine generally also includes being used for the 3rd lead 41 for controlling windscreen wiper to stop and the third wafer 411 being connected with the 3rd lead 41; it is communicated to car body control module 4 (BCM); such as the 3rd lead 41 and first lead 31 (or second lead 32) built-up circuit; so that when the first contact 311 (or the second wafer 321) and the third wafer 411 contact conductive part 12 so that the first lead 31 (or second lead 32) is connected with the 3rd lead 41 simultaneously; send signal to stop windscreen wiper to BCM, for example, braked using mechanical resistance.In addition, rain shaving electrical machine also includes commutator 2, commutator 2 is connected by HW High Way 21 and low speed signal line 22 with BCM modules 4, and thus commutator 2 is grounded makes to scrape brush assemblies switching between high-speed cruising and low speed operation to receive the signal of BCM modules 4.Connected mode between each lead and contact as can be seen from Fig. 4, each lead is preferably embedded among the housing of rain shaving electrical machine by injection.In addition, in Fig. 4, the sheet metal for constituting conductive part 12 is fixed on the surface of contact disc 1 by multiple buckles 14.
Referring next to Fig. 5,6 (a), 6 (b) explains in detail the water spray opportunity for how setting conductive part 12 accurately to control water jet assembly.As mentioned previously, each position during contact disc 1 is rotated by 360 ° with output shaft 13 have it is corresponding scrape brush assemblies scraped thereon stroke or under scrape corresponding windscreen wiper position in stroke, the position signalling of contact disc 1 thus can be sensed by contact.According to this, correspondence position is with same letter A in Fig. 5,6 (a), 6 (b), B, P, and T is indicated.
As shown in FIG., in one embodiment, the first contact 311, the second wafer 321 and the third wafer 411 are in the radial position of contact disc center of circle O different distance.When contact disc for example rotates along the arrow F directions indicated, the track of contact disc 1 and the contact point of each contact is along the circular arc that the line in contact to the center of circle is radius.With Fig. 5 and Fig. 6 (a), 6 (b) show it is common scrape brush assemblies exemplified by, its region scraped represents with 98, its move include periodically scraping stroke from stop position P to extreme higher position T and from extreme higher position T to stop position P under scrape stroke.Of course it is to be understood that the windscreen wiper system of the present invention is not limited to use in the windscreen wiper type of diagram, for example, in an alternative embodiment, windscreen wiper system can be used for front windscreen wiper, after keep off the rain and scrape, its region scraped or semi-circular arc etc..Now, it is expected that accurate control is scraped brush assemblies and scraped under in stroke to spray water from position A to stop position P, and sprayed water in upper scrape from stop position P to position B in stroke.To realize above-mentioned water spray opportunity, then conductive part 12, which is at least included in, scrapes brush assemblies from A to P into B motion process, corresponding to the first contact 311 and the first circular arc 121 of the track of the contact point of contact disc 1；Corresponding to the second wafer 321 and the second circular arc 123 of the contact point of contact disc 1, the first circular arc 121 and the second circular arc 123 are conductings.For example, first circular arc 121 can be adjacent with the second circular arc 123 or the first circular arc 121 can be connected by other current-carrying parts with the second circular arc 123, for example, in the 5 embodiment of figure 5, first circular arc 121 is connected with the second circular arc 123 by three-arc 122, a part for the track that three-arc 122 can be for the contact corresponding to the third wafer 411 and contact disc 1 when contact disc 1 rotates.As mentioned previously, after BCM receives berthing signal (such as driver sends), the initial point (point contacted first with the third wafer 411) 1221 of this section of circular arc determines that BCM promotes windscreen wiper to stop.In summary, during conductive part 12 at least includes expecting water jet water spray, the first circular arc 121 of the locus of points is contacted with the first contact 311 corresponding to contact disc 1 and the second circular arc 123 of the locus of points is contacted with the second wafer 321 corresponding to contact disc 1.First circular arc 121 need to be connected with the second circular arc 123, and for example both are adjacent or are connected by other conduction regions.
Contact disc in Fig. 5 rotates under the driving of motor along F directions, contacted because each contact is remained with contact disc 1, in contact disc after shown position turns over certain angle, each contact is contacted with the position corresponding to radius A of contact disc, now the first contact 311 contacts conductive part 12 with the second wafer 321 and turned on, and remain conducting before contact disc 1 turns over the angle of alpha+beta, thus electric current flows through the windscreen wiper water pump 3 being connected in Fig. 2 on path so that water jet assembly is sprayed water, after the contact point of contact and contact disc is corresponding to radius B location, first contact 311 contacts insulation division 11 with the second wafer 321, and the first lead 31 and the second lead 32 disconnect, water jet assembly is stopped, until next cycle.
By changing the shape of conductive part 12, specifically, for example, it can arbitrarily be set by the extension central angle of the first circular arc 121 of change and the second circular arc 123 and scrape the opportunity that water jet assembly is sprayed water in stroke up and down.Although the first circular arc 121 and the second circular arc 123 are continuous in figure, in an alternative embodiment, the circular arc that the first circular arc 121 and/or the second circular arc 123 can be also spaced apart by multistage is collectively formed, and this causes water jet assembly discontinuously to spray water.It should be appreciated that to ensure that injection flow rate is enough to be used in wiper unit clean windshield, in one embodiment, follower such as contact disc 1 often rotates 360 degree, and the first lead and the second lead are held in 40 degree to 320 degree of angular range.It is reflected on the contact disc 1 shown in Fig. 5, i.e. the central angle of the first circular arc 121 and the second circular arc 123 is in the scope of 40 to 320 degree.In one embodiment, contact disc 1 often rotates 360 degree, and the first lead and the second lead are held in 45 degree to 315 degree of angular range.In one embodiment, contact disc 1 often rotates 360 degree, and the first lead and the second lead are held in 50 degree to 310 degree of angular range.In one embodiment, contact disc 1 often rotates 360 degree, and the first lead and the second lead are held in 55 degree to 305 degree of angular range.In one embodiment, contact disc 1 often rotates 360 degree, and the first lead and the second lead are held in 60 degree to 300 degree of angular range.
In addition, conductive part 12 also includes three-arc 122 in Fig. 5 embodiment, three-arc 122 can arbitrarily extend, it can be set to the manufacture for being easy to whole conductive part 12, for example in conductive part 12 in the embodiment of sheet metal, three-arc 122 may extend away certain angle so that the shape of whole sheet metal is more convenient for manufacturing and with more preferably intensity etc..As illustrated in fig. 3, after BCM modules 4 receive windscreen wiper berthing signal, when contact 411 contacts conductive part 12 simultaneously with contact 311 (original area 1221 for corresponding to three-arc 122), BCM modules 4 carry out mechanical braking to windscreen wiper, for example contact disc 1 is braked, but due to inertia, contact disc 1 also will be turned over certain angle, until the position on contact disc corresponding to radius P and each contact pad, wiper arm reaches Fig. 5 and Fig. 6 (a) simultaneously, the stop position P shown in 6 (b).
Although according to Fig. 5 to 6 (a), 6 (b) describes the construction of the contact disc 1 in one embodiment according to the windscreen wiper system of the present invention, and in an alternative embodiment, contact disc can take various constructive alternatives.With reference to Fig. 7, it illustrates a kind of constructive alternative of contact disc, in this embodiment, each contact 311,411,321 is still along the radially fixed arrangement of contact disc 1, and the conductive part 12 on contact disc 1 is substantially in sector.When conductive part is made up of sheet metal, fan-shaped conductive part is easily fabricated and with more preferable intensity (being unlikely to deform).The first contact 311 and the second wafer 321 are rotated with contact disc 1 along F directions to contact with the conductive part 12 corresponded at radius location A on contact disc simultaneously, so that the first lead 31 and the second lead 32 are turned on, thus electric current promotes water jet assembly to spray water by windscreen wiper water pump 3, until the first contact 311 and the second wafer 321 are contacted with the position that contact disc corresponds to radius B, then, first lead 31 disconnects with the second lead 32, and water jet assembly is stopped.The work of water jet assembly includes windscreen wiper downward storke end and above scrapes the initial part of stroke.
Fig. 8 shows another alternative, wherein the first contact 311, the second wafer 321 and the third wafer 411 be not along the radial arrangement of contact disc 1, instead, arranged before and after the circumferencial direction of first contact 311 and the second wafer 321 along contact disc 1, and the third wafer 411 also can be arranged arbitrarily.Different from Fig. 7 embodiment, in the embodiment in fig. 8, water jet is always become a useful person work only when the first contact 311 and the second wafer 321 are contacted with conductive part 12 simultaneously.Sprayed water opportunity with Fig. 5 and Fig. 6 identicals to realize, the third wafer 411 may be arranged on the position of the later contact conductive part 12 of the first contact 311 and the rear of the second wafer 321.Contact arrangement in the embodiment cause contact will not while contact conductive part 12, prevent multiple contacts at the same contact conductive part 12 there may be transient current it is excessive caused by spark the problems such as.
