Abstract

The utility model discloses a large motor vehicle non-blind area windscreen wiper which comprises a drive mechanism, a left windscreen wiper arm, a right windscreen wiper arm, windscreen wiper blades on the left windscreen wiper arm and windscreen wiper blades on the right windscreen wiper arm. The drive mechanism is simultaneously matched with front end gears of the left windscreen wiper arm and front end gears of the right windscreen wiper arm through flexible racks. The large motor vehicle non-blind area windscreen wiper is characterized in that the specific way of how the drive mechanism is matched with the front end gears of the left windscreen through the flexible racks is that the flexible racks are meshed with an idler wheel which is meshed with the gear of the left windscreen wiper arm; the tail end of the left windscreen wiper arm is in a hinge connection with the middle of an upper left windscreen wiper arm through a left connecting rod, and the top end of the upper left windscreen wiper arm is in a hinge connection with the left top of a windscreen; the tail end of the right windscreen wiper arm is in a hinge connection with the middle of an upper right windscreen wiper arm through a right connecting rod; the top of the upper right windscreen wiper arm is in a hinge connection with the upper right of the windscreen; the upper left windscreen wiper arm and the upper right windscreen wiper arm are respectively provided with the windscreen wiper blades. Rain and dust on the lower middle of the windscreen and the upper middle of the windscreen are all wiped by the large motor vehicle non-blind area windscreen wiper, and therefore wiping area is increased, view distance of a driver is enlarged, safe driving is guaranteed well, and potential safety hazard is reduced.

Description

A kind of Large vehicle non-blind area Wiping device

Technical field

The utility model relates to a kind of windscreen wiper, particularly a kind of Large vehicle non-blind area Wiping device.

Background technology

Wiping device is one of modal important safety auxiliary accessories of power actuated vehicle, and the safe driving of chaufeur is had very important effect and meaning.Existing Large vehicle is (such as truck, bus, truck etc.) Windshield size is large, and the Wiping device structure on it is single, only rely on driver train drive two left and right wiper arms that swing in the same way and on rain shaving blade realize rainwater, dust scraping.Its scraping can only wiper arm can put and scope in carry out, the larger field range of Windshield middle and upper part all swipe less than, have the windscreen wiper blind zone problem.In driving procedure, directly affect the visual field of chaufeur, brought potential safety hazard.

The utility model content

The purpose of this utility model just provides a kind of Large vehicle non-blind area Wiping device, this kind Wiping device all can carry out rainwater, dust scraping to middle and lower part, the middle and upper part of Windshield, it is interval to increase scraping, enlarge vision field of driver, better guarantee safe driving, the reduction potential safety hazard of chaufeur.

The utility model realizes that the technical scheme that its goal of the invention adopts is, a kind of Large vehicle non-blind area Wiping device, comprise driver train, left wiper arm, right wiper arm, rain shaving blade on left wiper arm and the right wiper arm, driver train cooperates with the top gear of left wiper arm, right wiper arm by flexible rack simultaneously; It is characterized in that:

Described driver train by flexible rack with the concrete mode that the top gear of left wiper arm cooperates is: flexible rack and the wheel engagement of falling, the gear engagement of fall wheel and left wiper arm;

The terminal middle part by left connecting rod and upper left wiper arm of described left wiper arm is hinged, and the top of upper left wiper arm is articulated in the left top of Windshield; On the upper left wiper arm rain shaving blade is installed;

Described right wiper arm end is hinged by the middle part of right connecting rod and upper right wiper arm, and the top of upper right wiper arm is articulated in the right top of Windshield; On the upper right wiper arm rain shaving blade is installed.

Principle of work of the present utility model and process are:

Wiping device of the present utility model is when initial condition, left wiper arm, the outside horizontal symmetrical of right wiper arm place the bottom of Windshield, the upper right wiper arm that upper left wiper arm, the end that the end is articulated in the left top of Windshield is articulated in the right top of Windshield then vertically places respectively the Windshield arranged on left and right sides, and whole Wiping device does not affect the sight line of chaufeur.

When needs are blown rain or dedusting, start driver train; Driver train rotates by the right wiper arm of the gear drive at flexible rack, right wiper arm top, and driver train rotates by the left wiper arm of the gear drive at flexible rack, the wheel of falling, left wiper arm top.Because many wheels of falling in the drive line of left wiper arm, thereby so that left wiper arm, right wiper arm are not rotating to Windshield central authorities in the same way but in opposite directions.

Left wiper arm, right wiper arm when rotating in opposite directions, respectively by left connecting rod, right connecting rod drive upper left wiper arm, upper right wiper arm in opposite directions to the rotation of Windshield central authorities; When left wiper arm, right wiper arm upwards (in) when rotation reaches maximum radian, driver train contrarotation, left wiper arm, the in opposite directions sideway swivel outside Windshield of right wiper arm; Left connecting rod, right connecting rod also drive respectively upper left wiper arm, the in opposite directions sideway swivel outside Windshield of upper right wiper arm, until left wiper arm, right wiper arm are rotated down and reach maximum radian, the motor main shaft hand of rotation is again reverse.

So circulation, left wiper arm, right wiper arm swing back and forth in the Windshield middle and lower part, and upper left wiper arm, upper right wiper arm then swing back and forth in the Windshield middle and upper part, and 4 wiper arms cooperate, and realize rainwater, dust scraping to whole Windshield non-blind area.

Compared with prior art, the beneficial effects of the utility model are:

One, scraping non-blind area, scraping effect is good.

Wiping device of the present utility model has increased upper left wiper arm, upper right wiper arm and rain shaving blade thereof on the basis of existing common Wiping device, can to the middle and lower part scraping of Windshield, can carry out rainwater, dust scraping to the Windshield middle and upper part again; It is interval to have increased scraping, has solved the scraping blind zone problem that existing wiper exists, and has enlarged vision field of driver, further guaranteed chaufeur safe driving, reduced potential safety hazard.Be particularly suitable for motorcoach, bus, the full size vehicle of the large scale Windshield such as truck.

Two, wiper arm of the present utility model and rain shaving blade are existing device, just select wiper arm, rain shaving blade and the connecting rod of different size can be combined into four wiper blade structures of the present utility model, and it is simple in structure, and is easy to manufacture, are convenient to implement.

What three, Wiping device of the present utility model adopted is four-bar linkage, left (right side) upper wiper arm all is fixed on the Windshield with top ends, the end portion of the wiper arm group that left (right side) wiper arm forms, for two-point form supports, support wiper arm than existing single-point type, between its rain shaving blade and the Windshield contact larger, contact more abundant, it is cleaner even to swipe, better effects if, and the driving sight that provides is more clear.
