Abstract

The utility model relates to an improved bracket of windscreen wiper. Both ends of the main frame of a windscreen wiper are excavated. The top surface of the inner side of a middle frame is provided with an inclined burbling plate. The resistance force which is generated by high velocity air between the windscreen wiper and glass when an automobile travels is decomposed and utilized. When the windscreen wiper is used, the windscreen wiper can be appressed to the glass window of the automobile. The wiping effect of the windscreen wiper can be enhanced.

Description

Improved windscreen wiper

The utility model relates to a kind of improvement of rain brush supporting structure, and it is advanced at automobile, and to strike off the action of rainwater or foreign matter more certain effectively for a rain brush.

The rain brush supporting structure of now using can be divided into body frame, middle frame and little three part, wherein middle frame pivot closes the two side ends in body frame, little then pivot close in middle frame one side, and frame and little 's claw and the rain brush rubber that will have a rain brush rubber mount sheet promptly and make rain brush rubber fit in outside the motor-vehicle glass window surface to strike off action in utilizing.

But the rain brush support of now using only terminates in the body frame position and is provided with spoiler device as the anti-dress of aircraft wing, making automobile have relative air flows when advancing produces, when this air-flow is met to automobile face glass window, stream line pattern regardless of glass port, all can be because of air-flow produces back draught after touching glass port, so, make the rain brush on it of attaching to buoyance lift outside glass window, reduced the veneer tightness between rain brush rubber and glass, influence brushes effect.Therefore the spoiler device that is provided with near side one of the body frame position traditionally is and eliminates this reverse strength, but because of the design of tradition only forms the flow-disturbing phenomenon on body frame, be limited with the effect that is produced, simultaneously because of only being installed on the body frame, even this air-flow is directed at behind the air pressure of glass pane front, through in frame and little component and when reaching rain brush rubber, then because of limited through little joint counteracting effect when transmitting.

Therefore the purpose of the utility model is to provide a kind of two brush supports of improvement, it can make automobile decompose and utilize through resistance that air-flow produced between asking rain brush and glass advancing, and more can be close in motor-vehicle glass window when rain brush is used, strike off action to promote rain brush.

According to the rain brush support of the improvement of the utility model, it comprises: in the body frame, at least two little of frame and right quantity; Wherein body frame both sides formation " Qian " type framework reaches, close the movable axis position of middle frame with pivot, and middle frame forms twice " Qian " type framework with respect to side outside the body frame, to articulate little, and the inside end of the relative body frame of middle frame, then form the bifurcated claw, cooperate claw that little two end all form to grab the supporting blade that closes on the rain brush rubber simultaneously, and the axis hole of offering with body frame central portion branch, and can be on the windshield wiper axle drive shaft with complete Wiper system, in vehicle glass outside window rider-type brush remove rainwater or foreign matter; It is characterized in that:

Dig at the end face of it " Qian " type frame of body frame and to be set as sky, with hold be arranged in spoiler on the frame; Simultaneously, then link in it " Qian " type framework end outside body frame at middle chord position with other two spoilers; Or will increase the hole on the middle frame to hold little last spoiler with the design identical with body frame;

The relative flow windstream is through above-mentioned spoiler and plate as the anti-dress of aircraft wing when utilizing automobile to advance, and in providing the claw of frame and little 's claw one to the pressure of glass port surface direction, via the claw of middle frame and little the downward pressure that claw obtained, and make automobile when advancing, rain brush can more be close to the glass port surface, heals and becomes effective and make it strike off action.

According to the rain brush support of the improvement of the utility model, the aircraft wing of spoiler system as anti-dress wherein, the air-flow of the generation of will running at high speed flows through since then, so that middle frame or little 's claw downward pressure directly to be provided; And convexedly stretch in the relative interior of two " Qian " shape framework in the body frame outside at middle frame, and be connected with two spoilers with above-mentioned spoiler tool same design, make air-flow offer in the time of also flowing through since then to be articulated in claw one downward pressure of little of framework below.

Below, the embodiment shown in according to accompanying drawing illustrates the architectural feature and the operating principle of the utility model in detail.Being simply described as follows of accompanying drawing wherein:

On behalf of three-dimensional appearance of the utility model and part, Fig. 1 analyse and observe;

Fig. 2 represents among the utility model the top plane view of spoiler on the frame;

Fig. 3 represents among the utility model the lateral plan of spoiler on the frame;

Fig. 4 represents among the utility model the front view of spoiler on the frame;

Fig. 5 represents little that is articulated in the utility model under the framework.

In the rain brush supporting structure shown in Fig. 1, has a body frame 10, in at least two little 17 of frame 2 and right quantity, wherein body frame 10 both sides formation " Qian " type frame 14 reaches, put the position among the frame 2 in closing with pivot, side also forms twice " Qian " type framework 15 outside the body frame 10 and middle frame is equivalent to, to articulate little 17, and the inside end of middle frame 2 relative body frames 10, then form claw 18, cooperate little 2 simultaneously in claw 18 that two ends all form to grab the supporting blade (not shown) that closes on the rain brush rubber, the axis hole 13 that cooperates body frame 10 middle bodies 11 to be offered, and can be on the windshield wiper drive spindle with complete Wiper system, in vehicle glass outside window rider-type brush remove rainwater or foreign matter; Being characterised in that of the utility model: dig at it " Qian " type frame 14 of body frame and to be set as sky, with hold be seated in the spoiler 20 of frame 2; Simultaneously, terminal inboard in middle frame 2 they " Qian " type frameworks 15 with 21 bindings of two spoilers, have the flow-disturbing effect equally.Or, will dig a hole on the middle frame 2 to hold little last spoiler (not shown) to reach identical effect with the design identical with body frame.

Among shown in Fig. 2,3 and 4 in the frame 2, close with pivot 22 and body frame 10 pivots in the central, and right-hand part is positioned at () side under the body frame 10 in Fig. 2, and the left side convexedly stretches in outside the body frame 10, end face is provided with a spoiler 20 on the bond sites of its claw 18, this spoiler 20 is to tilt to claw 18 directions, be to utilize as shown in Figure 4 when running at high speed, spoiler below air-flow velocity produces a downward pressure greater than the top, except that the strength that oppositely starts rain brush of offsetting the bounce-back of air-flow and vehicle window, and then make rain brush more be close to vehicle window; And the relative interior of one-tenth two " Qian " frame body 15 outside outside the left side convexedly stretches in body frame 10, be connected with two plates 21 with above-mentioned spoiler 20 tool same design, make offer when air-flow is flowed through since then be articulated in framework 15 times little 17(as shown in Figure 5) claw 18 1 downward pressures; The downward pressure that is obtained via the claw of middle frame 2 and little 's claw 18, and make automobile when advancing, rain brush can more be close to glass pane front, heals and becomes effective and make it strike off action.

In sum, the utility model makes automobile when advancing after the improvement of the innovation on the rain brush supporting structure, rain brush can more be close to the vehicle glass surface, so to rain or foreign matter to strike off action more effective, conform with the requirement of utility model completely, so file an application in accordance with the law.
