Abstract
The utility model discloses a lifting device for an automobile windshield wiper. The windshield wiper rocking arm is connected with a windshield wiper lifting device which is composed of a lifting plunger, a lift control electromagnetic valve and a reset spring. The elevation and subsidence of the lifting plunger is controlled by the lift control electromagnetic valve and the reset spring. The windshield wiper rocking arm is provided with a recess, and the lifting plunger is just embedded in the recess of the windshield wiper rocking arm. The power-off state of the lift control electromagnetic valve is that the lifting plunger is positioned at the lift position in the recess of the windshield wiper rocking arm, and at this moment, the windshield wiper rocking arm is in the state of hoisting under the function of the lifting plunger. The power-on state of the lift control electromagnetic valve is that the lifting plunger is drawn to the falling position in the recess of the windshield wiper rocking arm. The utility model has the positive effects that when the lighting key of a car engine is locked, the windshield wiper rocking arm rises to a certain angle to make a certain interstice kept between a windshield wiper rubber strip and a windscreen, which ensures that the windshield wiper rubber strip can not have deformation because of long-term compaction, and avoids accumulating mud between the windshield wiper rubber strip and the windscreen.
Description
Technical field
The utility model relates to automobile, relates in particular to vehicle wiper, particularly a kind of vehicle wiper jacking system.
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 purpose of this utility model is to solve the problems referred to above that exist in the prior art, a kind of vehicle wiper jacking system is provided, described vehicle wiper jacking system 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 utility model adopts following technology to achieve these goals: a kind of vehicle wiper jacking system, 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 utility model 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 utility model 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 a preferred embodiment structural representation of the utility model vehicle wiper jacking system;
Fig. 2 is the plan structure scheme drawing of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of vehicle wiper jacking system 10 of the utility model, 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.
