Abstract
A kind of active windscreen wiper, belong to vehicular spare parts design field, be primarily characterized in that: active windscreen wiper is the original windshield wiper mechanism of transformation automobile, increase stepping motor, stepping motor and original windshield wiper propulsion source also connect, the input end of stepping motor is connected with electronic control unit ECU, and the mouth of stepping motor is connected with rain brush.The advantages such as the utility model has rain brush swing speed can be changed according to the speed of a motor vehicle, rainfall size or snowfall size, and the clear and safety of driver's seat is good.
Description
Technical field
The utility model relates to a kind of active windscreen wiper, belongs to vehicular spare parts design field.
Background technology
Traditional windshield wiper is made up of electrical motor, retarder, four-bar linkage, wiper axle, swept area of wiper blade assembly etc., generally have low speed, at a high speed, interval 3 gears.In this Wiper system, rain brush swing speed is selected by chaufeur setting.This rain brush, owing to can not change swing speed automatically, is in use difficult to meet operating needs.In following three kinds of situations, the drawback performance of transmission automobile rain brush is comparatively obvious: 1. in onesize rainfall, the speed of a motor vehicle is faster, rainwater is head-on more, at this moment the swing of rain brush can not change from Row sum-equal matrix swing speed because of the speed of a motor vehicle, easily causes driver's seat unclear, is unfavorable for traffic safety; 2. in driving conditions, chaufeur changes the swing state M/C that needs to divert one's attention to rain brush and completes setting, increases chaufeur burden, is unfavorable for traffic safety; 2. heavy rain sky or severe snow sky, rapidly and also the raindrop of large or thick and heavy snowflake beat on front windshield glass, the finite rate that windscreen wiper swings, cause the sight line of chaufeur to be affected, traffic safety is subject to very serious threat.
In sum, the problem being unfavorable for traffic safety is caused to be further improved because existing windshield wiper slew rate degree can not change with the change of rainfall or snowfall and the speed of a motor vehicle.
Summary of the invention
The purpose of this utility model is to solve the problem, there is provided one can according to rainfall size or snowfall size and speed of a motor vehicle height, the active windscreen wiper of automatic vehicles rain brush swing speed, be achieved through the following technical solutions: a kind of active windscreen wiper, comprise rain sensor, snowfall sensor, car speed sensor, electronic control unit ECU and stepping motor.Electronic control unit ECU input end is connected with car speed sensor with rain sensor, snowfall sensor, and its mouth is connected with stepping motor.Stepping motor and original windshield wiper propulsion source also connect, and stepping motor input end is connected with electronic control unit ECU, and stepping motor mouth is connected with rain brush.
The utility model compares the advantage of prior art: the swing speed of windshield wiper is followed the change of the speed of a motor vehicle, the change of rainfall or the change of snowfall and automatically adjusted, guarantee that chaufeur has the visual field clearly when the different speed of a motor vehicle, different rainfall or snowfall travel, be conducive to traffic safety.
Accompanying drawing explanation
Fig. 1 is the layout schematic diagram of active windscreen wiper described in the utility model.
Detailed description of the invention
Below in conjunction with embodiment accompanying drawing, the utility model is described further.
As shown in Figure 1, active windscreen wiper described in the utility model, comprises rain sensor, snowfall sensor, car speed sensor, electronic control unit ECU and stepping motor.Described rain sensor is used for responding to the size and number of the raindrop fallen on the windshield; Described snowfall sensor is for measuring the snowfall on Windshield; Described car speed sensor is used for detecting the speed of a motor vehicle of automobile; Described electronic control unit ECU input end is connected with described car speed sensor with described rain sensor, described snowfall sensor, and its mouth is connected with described stepping motor.The incoming signal of described electronic control unit ECU comprises rainfall or snowfall and the speed of a motor vehicle, and output signal sends to described stepping motor.Described stepping motor and original windshield wiper propulsion source also connect, and described stepping motor input end is connected with described electronic control unit ECU, and described stepping motor mouth is connected with rain brush.
(1) when rainfall or snowfall is constant, the speed of a motor vehicle is constant time, the incoming signal of described rain sensor or described snowfall sensor and described car speed sensor is passed to described electronic control unit ECU, described electronic control unit ECU outputs signal to described stepping motor, described stepping motor is failure to actuate, and maintains original rain brush state of kinematic motion.
(2) when rainfall or snowfall constant, the speed of a motor vehicle raises, or when the speed of a motor vehicle is constant, rainfall or snowfall increase, or rainfall or snowfall increase, when the speed of a motor vehicle raises, the incoming signal of described rain sensor or described snowfall sensor and described car speed sensor is passed to described electronic control unit ECU, described electronic control unit ECU outputs signal to described stepping motor, described stepping motor rotation direction is identical with the rotation direction of the rain brush input shaft that original windshield wiper propulsion source acts on, both superpositions, rain brush is driven jointly by original propulsion source and described stepping motor, rain brush power increases, thus improve the swing speed of rain brush.
(3) when rainfall or snowfall constant, the speed of a motor vehicle reduces, or when the speed of a motor vehicle is constant, rainfall or snowfall reduce, or rainfall or snowfall reduce, when the speed of a motor vehicle reduces, the incoming signal of described rain sensor or described snowfall sensor and described car speed sensor is passed to described electronic control unit ECU, described electronic control unit ECU outputs signal to described stepping motor, the direction of rotation of the rain brush input shaft that described stepping motor rotation direction and original windshield wiper propulsion source act on, both superpositions, rain brush is driven jointly by original propulsion source and described stepping motor, rain brush power reduces, thus reduce the swing speed of rain brush.
The utility model mainly provides a kind of foundation speed of a motor vehicle, rainfall or snowfall automatic vehicles rain brush swing speed to keep driver's seat active windscreen wiper clearly; driving safety can be improved; when not running counter to the utility model essence; the structural arrangement of active windscreen wiper can be done corresponding change, but these corresponding changes all should belong within the claims belonging to the utility model.
Claims (1)
1. an active windscreen wiper, comprise rain sensor, snowfall sensor, car speed sensor, electronic control unit ECU and stepping motor, it is characterized in that: described electronic control unit ECU input end is connected with described car speed sensor with described rain sensor, described snowfall sensor, described electronic control unit ECU mouth is connected with described stepping motor, described stepping motor and original windshield wiper propulsion source also connect, described stepping motor input end is connected with described electronic control unit ECU, and described stepping motor mouth is connected with rain brush.
