Description

The utility model relates to an improvement of the structure of a wiper bracket, which makes the action of the wiper to scrape off rainwater or foreign matter more reliable and effective when the car is running.

The current wiper bracket structure can be divided into three parts: the main frame, the middle frame and the small frame. The claws of the small frame grasp the wiper rubber with the wiper rubber support sheet, and make the wiper rubber adhere to the outer surface of the car glass window for scraping.

But the existing wiper bracket only stops at the main frame position and is provided with the reverse spoiler device as the wing of an airplane, so that the automobile has a relative air flow to produce when advancing. Regardless of the streamline shape of the glass window, the reverse airflow will be generated after the airflow touches the glass window. In this way, the wiper attached to it will float out of the glass window, reducing the tightness between the wiper rubber and the glass. Brush effect. Therefore, the spoiler device traditionally installed on one side near the main frame is to eliminate this reverse force, but because the traditional design only forms the turbulence phenomenon on the main frame, the effect produced is limited At the same time, because it is only installed on the main frame, even if the airflow is guided to the air pressure towards the glass window, when it is transmitted to the wiper rubber through the component force of the middle frame and the small frame, it will be offset by the joints of the small frame during transmission. The effect is limited.

Therefore, the purpose of this utility model is to provide an improved two-brush bracket, which can decompose and utilize the resistance generated by the airflow between the wiper and the glass when the car is moving, so that the wiper can be closer to the car glass when it is in use. window to enhance the wiping action of the wipers.

According to the improved wiper bracket of the present utility model, it includes: a main frame, at least two middle frames and an appropriate number of small frames; wherein the two sides of the main frame form a "凵"-shaped frame and are used to pivot the movable shaft of the middle frame position, and the middle frame forms two "凵"-shaped frames relative to the outer side of the main frame to pivotally connect the small frame, and the inner end of the middle frame relative to the main frame forms a bifurcated claw, which is matched with the two ends of the small frame The claws are all formed to catch the support piece on the wiper rubber, and the shaft hole opened in the central part of the main frame can be used to install the complete wiper on the drive shaft of the car wiper, and reciprocate to remove rainwater outside the car glass window or Foreign body; characterized by:

The top surface of the "凵"-shaped frame of the main frame is hollowed out to accommodate the spoiler installed on the middle frame; at the same time, in the end of the "凵"-shaped frame outside the main frame, another Connect the two spoilers; or use the same design as the main frame to add holes to the middle frame to accommodate the spoiler on the small frame;

When the car is moving, the relatively flowing air flows through the above-mentioned spoiler and plate, such as the reverse installation of the aircraft wing, to provide the pressure of the claws of the middle frame and the claws of the small frame towards the surface of the glass window, through the claws of the middle frame The downward pressure obtained by the upper part and the claw part of the small frame makes the wiper stick more closely to the surface of the glass window when the car is moving, so that its scraping action becomes more effective.

According to the improved wiper bracket of the present invention, the spoiler is like a reversed airplane wing, through which the airflow generated by high-speed driving flows through, so as to directly provide downward pressure on the claws of the middle or small frame; and In the opposite interior of the two "凵"-shaped frames protruding from the outside of the main frame, two spoilers with the same design as the above-mentioned spoiler are connected, so that the airflow can also be provided to the airflow when passing through it. Press down on the claws pivotally connected to the small frame below the frame body.

Hereinafter, the structural features and operating principles of the present utility model will be described in detail according to the embodiments shown in the accompanying drawings. A brief description of the accompanying drawings is as follows:

Fig. 1 represents the three-dimensional appearance and partial cross-section of the utility model;

Fig. 2 represents the top view of the spoiler on the shelf in the utility model;

Fig. 3 represents the side view of the spoiler on the shelf in the utility model;

Fig. 4 represents the front view of the spoiler on the shelf in the utility model;

Fig. 5 represents the small frame that the center of the utility model is connected under the frame body.

In the structure of the wiper bracket shown in Fig. 1, there is a main frame 10, at least two middle frames 2 and an appropriate number of small frames 17, wherein the two sides of the main frame 10 form "凵" type frames 14 and to pivotally At the midpoint of the frame 2, the middle frame is equivalent to the outer side of the main frame 10 and also forms two "凵"-shaped frames 15 to pivotally connect the small frame 17, while the inner end of the middle frame 2 relative to the main frame 10 forms a Claw part 18, cooperates with the claw part 18 that all forms at both ends of small frame 2 simultaneously to grab the support piece on the wiper rubber (not shown in the figure), cooperates with the axle hole 13 that main frame 10 central part 11 offers, and can Install the complete wiper on the driving rod of the automobile wiper, and reciprocate to remove rainwater or foreign matter outside the glass window of the automobile; The spoiler 20 of middle frame 2; Simultaneously, link with two spoilers 21 inboard of " 凵 " type frame body 15 end inboard of middle frame 2, have the effect of spoiling flow equally. Or with the same design as the main frame, the middle frame 2 is dug to accommodate the spoiler (not shown) on the small frame to achieve the same effect.

In the middle frame 2 shown in Figures 2, 3 and 4, the pivot 22 is pivoted with the main frame 10 in its center, and the right half is positioned at the lower (inner) side of the main frame 10 in Figure 2, while the left The side protrudes from the main frame 10, and a spoiler 20 is arranged on the top surface of the connecting part of the claw 18. This spoiler 20 is inclined toward the claw 18, so as shown in Figure 4 When driving at high speed, the speed of the airflow below the spoiler is greater than that of the top to generate a downward pressure, in addition to counteracting the force of the airflow and the rebound of the window to lift the wiper in the opposite direction, and then make the wiper closer to the window; Stretch outside the main frame 10 and form the opposite interior of two "Xuan" frame bodies 15, connect with two plates 21 with the same design as the above-mentioned spoiler 20, so that the air flow can be provided to the pivot joint when it flows through. The claw portion 18 of the small frame 17 (as shown in Figure 5 ) pivotally connected under the frame body 15 is pressed downward; the downward pressure obtained by the claw portion of the middle frame 2 and the claw portion 18 of the small frame makes the car When driving, the wiper can be more close to the glass window surface, so that its scraping action becomes more effective.

To sum up, after the innovation and improvement of the wiper bracket structure of the utility model, the wiper can be more closely attached to the glass surface of the car when the car is moving, so the scraping action of rain or foreign objects is more effective, which is completely practical Therefore, the application is filed in accordance with the law.
