Description

The air-cushion type Wiping device

Technical field

The utility model relates to a kind of automobile component, relates in particular to the air-cushion type Wiping device.

Background technology

Automobile can run into special weather situations such as rainy day under steam unavoidably, rainwater, the mud that splashes and other dirt are attached on the Windshield, can block driver vision, influence the normal running of chaufeur, this uses Wiping device to clear up timely with regard to needs.Traditional Wiping device is by component set-ups such as support arm, suspension and rubber strips, one end of support arm is connected with the output shaft of rain shaving electrical machine, the middle part of the other end of support arm and cantilever end face is fixed, and in the bottom of cantilever rubber strip is installed, and the bottom surface of rubber strip and Windshield applying.When rain shaving electrical machine turned round, support arm was done swing, and support arm drives the rubber strip motion by suspension, made the surface friction of rubber strip and Windshield, and ponding, dirt etc. is drained.Because Wiping device is in the process of work, rubber strip carries out repeated friction to glass surface for a long time, can cause adverse effect to the surface of Windshield, and when being attached with hard thing such as Shi Li on the Windshield, the surface with glass scratches easily; Simultaneously, the resistance of rubber strip and glass surface friction is bigger, and the load of rain shaving electrical machine is big like this, and long-time use causes rain shaving electrical machine to damage easily, does not ensure the service life of rain shaving electrical machine.In addition, when dried dirt is arranged on the Windshield, must dirt be got wet by nozzle water spray, just can wipe out by the rubber strip repeated friction, the required injection flow rate of this process is bigger, and effect is also undesirable.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of Windshield that can prevent to be scratched, also can effectively reduce the air-cushion type Wiping device of motor load.

The technical solution of the utility model is as follows: a kind of air-cushion type Wiping device, comprise support arm and suspension, one end of support arm is connected with the middle part of suspension end face, its key is: in the bottom of described suspension the strip shape air bag is installed, the bottom surface of this air bag is provided with a finedraw along its length direction, have with it the mozzle of arranging in the same way above air bag, be connected by arm between this mozzle and the air bag, three's inner chamber communicates; The closed at both ends of described mozzle, the inner chamber of the mozzle air inlet pipe interior with being arranged on described support arm is communicated with.

Adopt above technical scheme, air pump is installed in the position that is fit on automobile, and to the air inlet pipe air feed, high pressure gas enter in the mozzle by air inlet pipe by air pump, enters in the air bag through arm again, and the finedraw by the air bag bottom outwards blows out at last.The utility model adopts the principle of similar air cushion vehicle, utilize air between air bag bottom surface and windscreen surface, to form one deck air cushion, air bag is suspended, air bag itself does not contact with glass surface, like this under the effect of rain shaving electrical machine, air bag is with the support arm reciprocally swinging, and the high-speed gas that blows out from the air bag finedraw constantly blows the rainwater or the dirt of glass surface open, and is unaffected to ensure driver vision.Because direct contact not between air bag and the glass, when hard thing such as Shi Li was arranged when glass surface, the gas that blows out from the air bag finedraw can blow away hard things such as Shi Li, has prevented that effectively glass surface from being scratched; Simultaneously, the load during rain shaving electrical machine work reduces greatly, and rain shaving electrical machine is not fragile, and can correspondingly prolong service life.

In order to reach better cleaning effect, in the bottom of above-mentioned suspension two strip shape air bags are installed side by side, the top of each air bag is provided with mozzle, and each root mozzle is equipped with an air inlet pipe.

The longitudinal cross-section of above-mentioned air bag inner chamber is infundibulate, can lead to gas, can guarantee that again the gas that blows out has enough pressure.

For the structure that makes whole device compact more, above-mentioned mozzle is arranged in air-bag support, captiveing joint with the end face of air bag in the bottom of this air-bag support, in the two sides of air-bag support a positioning groove is set respectively, and this positioning groove cooperates with the junction button clamping of suspension bottom.

Above-mentioned suspension is made of a upper bracket and two lower brackets, wherein the middle part of upper bracket end face is connected with support arm, the two ends of upper bracket are fixed with the top of two lower brackets respectively, have two pairs of junction buttons that are rectangular in shape in the bottom of lower bracket, the horizontal edge of this junction button is arranged in the positioning groove of described air-bag support side, be connected between air-bag support and the lower bracket so reliable, easy accessibility.

Evenly, above-mentioned air inlet pipe arranges that along support arm the outlet of this air inlet pipe communicates with the middle part of isocon for the gas that enters in the mozzle is continued, and two of isocon is connected with the end face of mozzle.

Next door at above-mentioned air inlet pipe is provided with coolant inlet pipe, and the outlet of this coolant inlet pipe communicates with the inner chamber of air inlet pipe.Position suitable on automobile is provided with water jet pump, water jet pump links to each other with coolant inlet pipe, in the time need clearing up the dirt of doing, water jet pump is opened water supply, and water enters in the air inlet pipe by coolant inlet pipe, under the effect of high pressure gas, atomize, form fog, fog acts on windscreen surface by the air bag finedraw, can fast the dirt of doing be decomposed and blow open, the injection flow rate that not only needs is few, and respond well.

Beneficial effect: the utility model utilizes the air cushion suspension theory, adopts high pressure gas the rainwater of windscreen surface, the mud that splashes and other dirt can be cleaned out, thereby has avoided glass surface to be scratched; Simultaneously, the load during rain shaving electrical machine work is less, and rain shaving electrical machine is not fragile, and can correspondingly prolong service life.The utility model goes for any vehicle, so train, steamer, aircraft etc. other need the place of windscreen wiper work.
