25 or second different sizes is taken between engaging tooth 29, can further ensure that phase synchroniser 23 with power input shaft 28 one
The stability of individual swing circle internal messing.
The frontal windshield rain brush lazy-tongs use principle of the present invention is as follows：
Before it need not be controlled to windscreen wiper, two rain brush actuators 2 (drive respectively main rain brush and
One secondary rain brush) in, the drive mechanism built in power output shaft 21 is that control power input shaft 28 departs from phase synchroniser 23.
When needing to open main rain brush, the first operator can control the first motor 1 to open by the first controlling switch
Open, now the first motor 1 can drive two power input shafts 28 to rotate (idle running)；Control again in main rain brush drive mechanism
The second motor rotate so that power input shaft 28 engages with phase synchroniser 23 in main rain brush drive mechanism, so that band
Dynamic main rain brush rotates；Also, the controlling switch of the motor of the first motor 1 and second therein can be same opens
Close, can be connected and realized by the circuit of routine, here is omitted.
In the case where main rain brush has been switched on state, when the second operator needs to open secondary rain brush, can be opened by the second control
Pass controls the second motor in secondary rain brush drive mechanism to rotate, and (the first motor 1 is in opening, and secondary rain
The power input shaft 28 of brush element is also constantly in idling conditions) so that power input shaft 28 and phase in secondary rain brush drive mechanism
Bit synchronizer 23 engages, and is in a swing circle internal messing, so as to drive secondary rain brush to rotate.Due to major-minor power output shaft
21 have identical output phase, enable to major-minor rain brush synchronous axial system.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, the change or replacement that can readily occur in, all should
It is included within the scope of the present invention.Therefore, protection scope of the present invention should using the scope of the claims as
It is accurate.
