The course of work and original of laser controlling automobile wiper speed change gear described in the utility model described further below
Reason：
When in the rainy day, traveling is provided with the automobile of laser controlling automobile wiper speed change gear described in the utility model,
Automobile wiper is adjusted to into automatic catch, then the laser controlling automobile wiper speed change gear starts.Rainwater is along automobile front wind screen
Glass 20 is to dirty, and is flowed in storage tank 11 by the water inlet 111.When rainfall is less, flow in storage tank 11
Rainwater is flowed out by outlet 112, and the water level in storage tank 11 is relatively low.As holding tank 114 is connected with storage tank 11, thus hold
The water level received in groove 114 is identical with the water level in storage tank 11, and now kickboard 115 can not block any beam of laser, thus control
What device processed was simultaneously received is ABC signals, and controller control rain brush keeps original operating rate F.When rainfall is incrementally increased,
When water in the inflow storage tank 11 of water inlet 111 can not be flowed out by outlet 112 in time, on the water level in storage tank 11
Rise, until kickboard 115 can block first through hole 1141, the first laser receiving unit 131 is swashed from receiving first
The laser signal of the transmitting of Optical Transmit Unit 121, when now controller receives A ' BC signals simultaneously, controller control rain brush is improved
Operating rate is to F '.When rainfall continues to incrementally increase, flowing into the water in storage tank 11 along water inlet 111 can not pass through in time
When the mouth of a river 112 and the first discharge outlet 113a flow out, the water level in storage tank 11 goes up, until kickboard 115 can block first leading to
Hole 1141 and the second through hole 1142, prevent the first laser receiving unit 131 from receiving first laser transmitter unit 121
The laser signal penetrated, the second laser receiving unit 132 can not receive the laser letter of the transmitting of second laser transmitter unit 122
Number, when now controller receives A ' B ' C signals simultaneously, controller control rain brush improves operating rate to F ".When rainfall continues
When incrementally increasing, the water in storage tank 11 is flowed into along water inlet 111 and can not pass through outlet 112, the first discharge outlet 113a in time
When flowing out with the second discharge outlet 113b, water level in storage tank 11 goes up, until kickboard 115 can block first through hole 1141,
Second through hole 1142 and third through-hole 1143, prevent the first laser receiving unit 131 single from receiving first laser transmitting
The laser signal of 121 transmitting of unit, the second laser receiving unit 132 can not receive second laser transmitter unit 122 and launch
Laser signal, the 3rd laser pick-off unit 133 can not receive the 3rd laser emission element 123 transmitting laser letter
Number, when now controller receives A ' B ' C ' signals simultaneously, controller control rain brush improves operating rate to F " '.And work as rainfall
After reduction, controller controls rain brush again according to the change of signal and is down to different operating rates.So that the laser control
Automobile wiper speed change gear processed can automatically control the operating rate of rain brush, convenient use according to the size of rainfall.
Relative to prior art, a kind of laser controlling automobile wiper speed change gear described in the utility model, according to storage
Water in Water Tanks position height controls the reception of laser signal by kickboard, and whether the laser signal launched according to laser emission element
Transmit to laser pick-off unit, be converted into different electrical signals, transmit to controller, controller controls rain brush according to the signal of telecommunication
Operating rate.
This utility model is not limited to above-mentioned embodiment, if do not taken off to various changes of the present utility model or deformation
From spirit and scope of the present utility model, if these are changed and deformation belongs to claim of the present utility model and equivalent technologies
Within the scope of, then this utility model is also intended to comprising these changes and deforms.
