Abstract
The elevating mechanism for rocker of windscreen wiper is connected to rocker of windscreen wiper and consists of elevating plunger, elevation controlling solenoid valve and repositioning spring, and the elevating plunger is controlled to elevate with the elevation controlling solenoid valve and the repositioning spring. The rocker of windscreen wiper has one notch for the elevating plunger to be embedded in. When the elevation controlling solenoid valve is powered off, the rocker of windscreen wiper is elevated under the action of the elevating plunger, and when the elevation controlling solenoid valve is powered on, the rocker is lowered by the attracted elevating plunger. The present invention makes the rocker of windscreen wiper elevated by some height after the engine is stopped, and this can avoid the deformation of rubber strip in windscreen wiper and the silt deposition between the rubber strip and the windscreen.
Description
Technical field
The present invention relates to automobile, relate in particular to vehicle wiper, particularly a kind of lifting mechanism that is used for windscreen wiper arm of automobile.
Background technology
Conventional truck, comprise uses such as automobile, construction machinery and equipment and trac. wiper by the rain brush rocking arm with drive rocking arm and constitute, an end that drives rocking arm is connected with axle drive shaft by bearing pin, the rain brush rocking arm is connected with the other end that drives rocking arm, be provided with extension spring between rain brush rocking arm and the driving rocking arm, the rain brush rocking arm is provided with the rubber wiper strip.After automobile dispatched from the factory, in logistics, stock, displaying, marketing and in the stagnation of movement process, the rubber wiper strip was pressed on the windscreen under the extension spring effect, caused the distortion of rubber wiper strip and the water-based energy is scraped in the early failure influence.In addition, automobile is in parking and driving process, between windscreen and the rubber wiper strip, accumulated a large amount of silt, opened wiper in case of raining in the way, the silt that accumulate this moment has become abrasive material, can cause wearing and tearing to scratch to windscreen, influence adverse effects such as pilot's line of vision.
Summary of the invention
The objective of the invention is to solve the problems referred to above that exist in the prior art, a kind of lifting mechanism that is used for windscreen wiper arm of automobile is provided, the described lifting mechanism of windscreen wiper arm of automobile that is used for is when the wiper withdraw from use, make the rain brush rocking arm rise certain angle, make between rubber wiper strip and the windscreen and keep certain interval, can avoid the rubber wiper strip to be subjected to press for a long time like this and be out of shape, can avoid again accumulating silt between rubber wiper strip and the windscreen.
The present invention adopts following technology to achieve these goals: a kind of lifting mechanism that is used for windscreen wiper arm of automobile, constitute by rain brush rocking arm and lifting plunger, described rain brush rocking arm is connected with an end of the driving rocking arm of vehicle wiper, the other end of the driving rocking arm of vehicle wiper is connected with axle drive shaft, be provided with extension spring between the driving rocking arm of described rain brush rocking arm and vehicle wiper, described rain brush rocking arm is provided with the rubber wiper strip, wherein, one side of described rain brush rocking arm is provided with a groove, one end of described lifting plunger is located in the described groove, the other end of lifting plunger is connected with a lifting control electromagnetic valve, and described lifting control electromagnetic valve is fixedly installed on the vehicle body.
Further, described groove is arranged on the side of described rain brush rocking arm towards the automobile windscreen.
Further, be provided with retracing spring between described lifting plunger and the vehicle body.
Principle of work of the present invention is: the lifting of lifting plunger is by lifting control electromagnetic valve and retracing spring control, during the outage of lifting control electromagnetic valve, the lifting plunger rises under the return spring pressure effect, the rain brush rocking arm is in the lifting state, make between rubber wiper strip and the windscreen to keep certain interval, during the energising of lifting control electromagnetic valve, the lifting plunger is descended by the adhesive of lifting control electromagnetic valve, the rain brush rocking arm is in the work ready position, and the rubber wiper strip contacts with windscreen.
The present invention compared with the prior art, its advantage is: when the wiper withdraw from use, the rain brush rocking arm rises certain angle, make between rubber wiper strip and the windscreen and keep certain interval, so both avoided the rubber wiper strip to be subjected to press for a long time and be out of shape, and avoided again accumulating silt between rubber wiper strip and the windscreen.
Description of drawings
Fig. 1 is that of a kind of lifting mechanism that is used for windscreen wiper arm of automobile of the present invention is preferable
The example structure scheme drawing;
Fig. 2 is the plan structure scheme drawing of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of lifting mechanism 10 that is used for windscreen wiper arm of automobile of the present invention, constitute by rain brush rocking arm 20 and lifting plunger 11, described rain brush rocking arm 20 is connected with an end of the driving Rocker arm 50 of vehicle wiper by bearing pin 40, the other end of the driving Rocker arm 50 of vehicle wiper is connected with axle drive shaft 60, be provided with extension spring 30 between the driving Rocker arm 50 of described rain brush rocking arm 20 and vehicle wiper, described rain brush rocking arm 20 is provided with the rubber wiper strip, wherein, one side of described rain brush rocking arm 20 is provided with a groove 21, one end of described lifting plunger 11 is positioned at described groove 21 (when wiper quits work), the other end of lifting plunger 11 is connected with a lifting control electromagnetic valve 12, and described lifting control electromagnetic valve 12 is fixedly installed on the vehicle body.
Further, described groove 21 is arranged on the side of described rain brush rocking arm 20 towards the automobile windscreen.
Further, be provided with retracing spring 13 between described lifting plunger 11 and the vehicle body.
Concrete, the operating voltage of lifting control electromagnetic valve 12 is controlled by the automotive ignition key switch, the parking of automobile rear engine is flame-out, 12 outages of lifting control electromagnetic valve, under retracing spring 13 effects, lifting plunger 11 is in raised position in the groove 21 of rain brush rocking arm 20, lifting plunger 11 lifting travels are d, this moment, rain brush rocking arm 20 was in the lifting state under the effect of rain brush extension spring 30 and lifting plunger 11, make between rubber wiper strip and the windscreen and keep certain interval, can guarantee that like this rubber wiper strip avoids pressing for a long time and be out of shape, avoid again accumulating silt between rubber wiper strip and the windscreen.In a single day automobile enters the preparation running state, 12 energisings of lifting control electromagnetic valve, lifting plunger 11 is descended by adhesive under 12 effects of lifting control electromagnetic valve in the groove 21 of rain brush rocking arm 20, at this moment the readiness for operation that is in very close to each other between rubber wiper strip and the windscreen.
