Detailed description of the invention
As shown in Fig. 1 ~ 4, a kind of rain brush rises device automatically, be applicable to jack-up rain brush and be connected with combustion engine, comprise housing 1 and push rod 2, housing comprises separation membrane 7 and spring 6, described housing 1 is divided into left space 4 and right space 5 by separation membrane 7, and right space 5 is connected with combustion engine, and right space 5 is located at by spring 6, spring 6 one end is connected with separation membrane 7 lower surface, and spring 6 other end is connected with housing; Push rod 2 lower end is stretched into described left space 4 and is connected with separation membrane 7 upper surface, and rain brush 8 is arranged at push rod 2 upper end; When described internal combustion engine start, in housing 1 right space 5, air is extracted out by combustion engine and produces vacuum, spring 6 is compressed and allows separation membrane 6 move down and push rod 2 is moved down; Push rod 2 also comprises a roller 3, and roller 3 is arranged at push rod 2 upper end, and supports rain brush 8, and housing right space 5 is connected with described induction system of internal combustion engine, and the utility model device is installed in windshield 10 front.
As shown in Figure 2, when after internal combustion engine start, combustion engine can suck a large amount of air from air system, and the air in the right space 5 be connected with induction system of internal combustion engine will be taken away by combustion engine, and forms the state of vacuum in right space 5.Now, be vacuum state in right space 5, left space 4 is still bar pressure, and because left space 4 and the difference of pressure of right space 5 will overcome the tension force of spring 6, separation membrane 7 will move down and Compress Spring 6, and push rod 2 also can move down with work separation membrane.
The vacuum that induction system of internal combustion engine can produce is the operational situation depending on combustion engine, and the rotating speed of combustion engine is higher, and the vacuum produced is also higher, and general combustion engine can produce the vacuum of 18 in-hg at idling mode.The suction that spring 6 is subject to 7 in-hg vacuum will be compressed, and therefore the rain brush jacking system of the utility model vacuum that can't produce because of combustion engine is not enough and cannot act on.When combustion engine is closed, combustion engine stops sucking air, and the vacuum of air system fades away and close to bar pressure.Now, the vacuum in right space 5 weakens and cannot resist the tension force of spring 16, and separation membrane 7 will be subject to the tension force impact of spring 6 and move up, and push rod 2 also can move up with work separation membrane 7.
