Five, the specific embodiment:

Consult shown in Figure 1, the jacking system of the utility model control Wiper arm, it is made of lifter 3, lifter bracing frame 4, Wiper arm pedestal 10, wherein, lifter bracing frame 4 is connected one with lifter 3, and is fixed in Wiper arm pedestal 10, Wiper arm 1 is fixed on the Wiper arm pedestal 10, become a upper and lower covers zoarium, in conjunction with the time, Wiper arm 1 covers lifter 3 and lifter bracing frame 4.

Consult shown in Figure 2ly, when the push rod 6 in lifter 3 outsides was horizontal, Wiper arm 1 as usual state were for being in the decline state.Consult shown in Figure 3, when the push rod 6 in lifter 3 outsides according to anticlockwise direction when turn round in the upright position, because the length that push rod 6 has is enough to play the effect that raises Wiper arm 1, when the end of push rod 6 withstands Wiper arm 1 inner upper limb, form a stress point 9, again, because of lifter bracing frame 4 is to be fixed on Wiper arm pedestal 10, and with pedestal 10 is bearing pressure, produces Zhi Lidian 8, so lifter can be not sagging, make push rod 6 can raise Wiper arm 1, when push rod is docile and obedient clockwise running when getting back to level attitude, the elastic force effect of the spring 2 that is provided with by Wiper arm 1, Wiper arm 1 is got back to lowering position.

Consult shown in Figure 4, the lifter 3 of connection one and lifter bracing frame 4 and Wiper arm 1 are fixed on Wiper arm pedestal 10 by rivet 7, become a lid up and down, power control line 5 is connected in automobile circuit, rotation and parking place with control lifter 3 push rods 6 reach the dipping and heaving of control Wiper arm 1.

Consult Fig. 5, Fig. 6, shown in Figure 7, lifter 3 is main devices of control Wiper arm, it is provided with the sealed plastic outer cover 16 of a strip shape, be fixed with magnet valve switch 14 successively in this outer cover 16, Direct Current Motor 15, gear cluster and two cut-

off switchs

11,12, this gear cluster is by transmission gear, intermediate gear and low-gear are formed, it has deceleration effort, impel push rod with slow rotation, strengthen motive force, to raise Wiper arm 1, push rod 6 is fixed on the axle center of the low-gear that extends to outer cover, and with this gear run-in synchronism, when the terminal running of push rod 6 to 12 o'clock during direction, with Wiper arm 1 inner upper limb is stress point, because of this lifter 3 and lifter bracing frame 4 are to combine fixingly on Wiper arm pedestal 10, has bracing force again, so can raise Wiper arm 1, this low-gear device on one side has a nose bar 13, just can push away cut-off switch and cuts off the power supply, and motor 15 is shut down, make push rod rest on the vertical direction at 12 o'clock, finish the operating position of push rod.

Consult Fig. 8, shown in Figure 9, the utility model is with after automobile circuit is connected, when vehicle switch 17 is opened, 14 energisings of relay magnet valve switch, magnet valve is jumped and is driven cut-off switch B to the other end, form the B loop, make motor 15 be docile and obedient the clockwise rotation, driven gear group running drives to push rod 6 ends and ran to for 3 o'clock during horizontal direction, and Wiper arm 1 descends, rain brush is fitted on the Windshield, nose bar 13 was pushed cut-off switch 12 open and was cut off the power supply this moment, cause driving during rain brush be fitted in all the time on the Windshield, can not influence the action and the function thereof of rain brush.When automobile parking, vehicle switch 17 is closed, 14 outages of relay magnet valve switch, magnet valve is jumped to the other end, driving is connected the loop of the cut-off switch A of direct supply (automobile batteries) 18, and the both positive and negative polarity of converting power source drives Direct Current Motor 15 to the anticlockwise direction rotation, the running of driven gear group, when the vertical direction of push rod 6 terminal runnings to 12 o'clock, Wiper arm 1 also raises, and rain brush leaves Windshield, and at this moment nose bar 13 is pushed cut-off switch 11 open and cut off the power supply, therefore rain brush is in the rise state all the time during the automobile parking, leave Windshield, circulation running like this reaches rain brush automatic lifting function.Using the purpose of this utility model is when making automobile parking, rain brush raises automatically by lifter 3, separate with Windshield, thereby can avoid dust or snow-broth to hoard and the rain brush upper limb, also can avoid rain brush to be out of shape, prolong the service life of rain brush because of the daylighting hyperthermia irradiation, start, during starting switch, rain brush pastes back Windshield again, to clean vehicle glass with water.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
