The main bracket in the embodiment of the invention is equivalent to a wiper blade bracket in the prior art, and the wiper blade bracket in the prior art is used for supporting and connecting a rubber wiper blade, is movably connected with a wiper arm and can reciprocate under the drive of the wiper arm. Therefore, the connection mode of the main bracket and the wiper arm is not described in detail herein.
According to the windscreen wiper provided by the invention, dust on the surface of the windscreen can be cleaned by the hairbrush, so that the dust removal effect on the windscreen is improved, the service life of the rubber scraper is prolonged, and the windscreen is prevented from being scratched in the dust removal process of the windscreen.
The scraping blade 1 can be a rubber scraping blade, and bristles of the hairbrush 4 can be made of animal hair or soft materials such as rubber, so that the windshield can be prevented from being scratched in the dust removing process.
As shown in fig. 2 and 3, in some embodiments, in the wiper blade with a dust removing function, the brush assembly includes a plurality of brushes 4, the plurality of brushes 4 are sequentially disposed on the brush holder 3, each brush 4 is rotatably disposed on the brush holder 3 through a brush holder 7, and the brush holder 7 extends substantially perpendicular to the windshield in a state where the brush 4 is in contact with the windshield 6.
In this embodiment, a plurality of brushes 4 are arranged in a row on the brush holder 3 on the side of the blade 1. And each brush can independently rotate relative to the own brush seat. Specifically, the handle portion (i.e., the brush holder) of the brush 4 and the brush holder 3 are in a shaft hole assembly form, and are in clearance fit. When dust is removed, the scraping blade is lifted, the brush is attached to the windshield, the windscreen wiper reciprocates, friction force is formed between the brush 4 and the windshield 6 in the reciprocating motion process of the brush assembly, and the brush 4 is driven to rotate by the friction force, so that the purpose of removing dust on the windshield is achieved. The brush works in a manner similar to a broom of a garbage sweeper. The design structure is simple, the dust removal capacity is strong, and the service life of the rubber windscreen wiper is prolonged.
In some examples, in the wiper blade with a dust removing function, the brush holder 7 is connected to a rotary driving mechanism, and is driven by the rotary driving mechanism to rotate relative to the brush holder 3. The rotary driving mechanism can drive the brush seat to rotate, and then the brush is driven to rotate, so that the dust removal effect of the brush on the windshield is further improved. The rotary drive mechanism may be a synchronous belt drive, a gear drive, a chain drive, or the like.
As shown in fig. 2 and 3, in some embodiments, in the wiper blade with a dust removing function, the brush holder 3 and the blade holder 2 are connected to the main holder through a switching mechanism, and the brush 4 and one of the blades 1 are in contact with the windshield 6 under the driving of the switching mechanism, and the other is suspended in front of the windshield 6.
In this embodiment, the brush assembly and the wiper blade assembly do not operate simultaneously, and are switched by the switching mechanism. Specifically, when the wiper blade bracket moves under the driving of the switching mechanism, so that the wiper blade is in contact with the windshield, the brush is suspended on the front side of the windshield and is not in contact with the windshield. At this time, the wiper blade assembly can work, and the wiper blade can wipe off rainwater on the surface of the windshield during the reciprocating motion of the windscreen wiper. When the brush bracket moves under the driving of the switching mechanism, the brush is contacted with the windshield, and the scraping blade is suspended at the front side of the windshield and is not contacted with the windshield. At the moment, the brush assembly can work, and the brush can remove dust on the surface of the windshield during the reciprocating motion of the windscreen wiper. Based on the design, the service life of the brush and the scraping blade is prolonged.
In some embodiments, the switching mechanism includes a shaft 5, the shaft 5 is pivotally connected to the main bracket, the blade bracket 2 and the brush bracket 3 are connected to the shaft 5, and the shaft 5 rotates at different angles to cause one of the brush 4 and the blade 1 to contact the windshield 6 and the other to suspend in the front of the windshield 6. The switching of the brush assembly and the wiper blade assembly can be achieved by operating the shaft of the switching mechanism so that one of them can be brought into an operating state.
Specifically, when neither the brush nor the blade cleans the windshield, both are kept at a distance from the windshield, and when one of the brushes and the blade needs to clean the windshield, one of the brushes and the blade is swung to a position where it can contact the windshield by adjusting the shaft. When the hairbrush and the scraping blade do not clean the windshield, one of the hairbrush and the scraping blade can be always kept in a state of being contacted with the windshield, for example, even when the scraping blade does not clean the windshield, the scraping blade is always kept in contact with the windshield, the hairbrush is correspondingly suspended in the front side of the windshield, when the hairbrush is required to clean the windshield, the scraping blade is lifted, and the hairbrush is switched to a position where the hairbrush can be contacted with the windshield.
Specifically, the shaft of the switching mechanism is arranged on one side of the scraping blade support, and the outer wall of the shaft is connected with a shifting fork which is connected to the brush support. Further, the switching mechanism may be a cam structure, a cylinder structure, a link structure, or the like.
In some examples, in the wiper blade with a dust removing function, one end of the shaft 5 is provided with a rotary dial button. Specifically, the rotation angle of the shaft can be adjusted by operating the rotation dial knob, and the wiper blade or the brush is brought into contact with the windshield, so that rainwater can be scraped off from the surface of the windshield or dust can be removed. For example, the rotating toggle button is operated to rotate the axial direction anticlockwise, so that the brush is lifted, and the scraping blade is contacted with the windshield; the rotating toggle button is operated to rotate the axial direction clockwise, so that the scraping blade is lifted, and the brush is contacted with the windshield.
In some embodiments, as shown in fig. 4, in the wiper blade with dust removing function, the blade holder 2 and the brush holder are fixedly connected as a whole, the shaft 5 is rotatably connected to the whole of the blade holder 2 and the brush holder, and the brush 4 and the blade 2 are respectively located at two sides of the whole of the blade holder 2 and the brush holder.
Specifically, in this embodiment, the cleaning surface of the brush and the cleaning surface of the wiper blade may be parallel to each other and located on both sides of the whole body formed by the wiper blade holder and the brush holder, respectively. By operating the shaft, switching between the blade and the brush can be realized. Here, it is also possible to provide the brush on the back of the blade holder so that the blade and the brush are located on both sides of the blade holder, respectively, in which case the blade holder also serves as a brush holder for providing a fixed support for the brush.
In some embodiments, as shown in fig. 5, in the wiper blade with dust removing function, the brush holder 3 and the blade holder 2 are fixedly connected to the main holder, and the brush 4 and the blade 1 are located at the same height position on the front side of the windshield, so that the brush 4 and the blade 1 are simultaneously in contact with the windshield 6.
In this embodiment, the brush and the wiper blade can be simultaneously brought into contact with the windshield, that is, dust can be removed from the surface of the windshield and rainwater can be scraped off. This will result in a reduced life of the wiper blade and the brush.
