The windscreen wiper of most motorcycle types configuration in the existing market has great instantaneous acceleration when scraping arm doctor-bar assembly and being in upper extreme position switching-over, and produces great instantaneous frictional force between with the windscreen, leads to windscreen to scrape arm doctor-bar assembly effect great impact force to the windscreen, and then reduces the life of windscreen wiper.
In view of the above, fig. 1 is a schematic structural view of a first embodiment of the wiper link mechanism of the present invention, and fig. 2 is a schematic structural view of the connection between the elastic element and the second link and the second output crank in fig. 1. Referring to fig. 1 and 2, in a first embodiment of the present invention, the wiper link mechanism 100 includes:
a wiper motor assembly 110;
a connecting rod drivingly connected to the wiper motor assembly 110;
the output crank is rotationally connected with the connecting rod and used for driving the scraping arm and scraping blade assembly to rotate; and
and an elastic member 150 having one end connected to one end of the connecting rod connected to the output crank and the other end connected to the output crank.
In the prior art, when a wiper arm wiper blade assembly of a windscreen wiper swings to an upper limit position, namely, is close to the upper edge of windscreen and is ready to change direction and swing back, instantaneous acceleration of the back swing is high, so that instantaneous friction between the wiper arm wiper blade assembly and the windscreen is high, impact force of the windscreen reacting on the wiper arm wiper blade assembly is high, and the service life of the wiper arm wiper blade assembly is further shortened. In particular, when the arm wiper blade assembly is used for a period of time and has a problem of aging deformation, the abutting surface of the arm wiper blade assembly and the windshield glass changes at the upper limit position, so that the pressing force between the arm wiper blade assembly and the windshield glass changes, and the instantaneous friction between the arm wiper blade assembly and the windshield glass increases when the arm wiper blade assembly is reversed.
Fig. 3 is a schematic diagram of the operation of the wiper linkage of fig. 1 when the wiper motor is in a reversing position, in which the wiper arm and the wiper blade assembly are in an upper limit position, and fig. 3 illustrates the force F2 ' of the wiper motor on the second output crank at this time, and the force Fk ' of the elastic element on the second output crank, wherein Fk ' is greater than 0.
Referring to fig. 3, according to the present invention, the elastic member 150 disposed between the connecting rod and the output crank can apply an elastic force Fk' to the output crank, thereby reducing the instantaneous acceleration of the wiper blade assembly during the reversing. Specifically, when the arm scraping blade assembly is at the upper limit position and is ready to reverse and swing back, the elastic acting force Fk 'and the force F2' acting on the output crank by the connecting rod are arranged in opposite directions, so that the driving acting force of the connecting rod on the output crank can be reduced, the instantaneous acceleration of the arm scraping blade assembly connected to the output crank when reversing and swinging back is reduced, the instantaneous friction force between the arm scraping blade assembly and the windscreen is further reduced, the instantaneous impact force of the windscreen acting on the arm scraping blade assembly is also reduced, the wiper connecting rod mechanism is further improved, and the service life of the windscreen wiper is also prolonged. In addition, because the instantaneous friction between the wiper arm wiper blade assembly and the windshield glass is reduced when the wiper arm wiper blade assembly reverses and swings back, the movement noise generated by the friction between the wiper arm wiper blade assembly and the windshield glass can be weakened, and the user experience can be improved.
Referring to fig. 2, in the first embodiment of the present invention, optionally, the elastic element 150 is an extension spring. When the scraper arm blade assembly is in the upper limit position and is reversed, the tension spring exerts tension Fk' on the output crank due to the tension of the tension spring, so that the driving acting force of the connecting rod on the output crank is reduced, and the instantaneous acceleration of the reversing of the scraper arm blade assembly is reduced. And the elastic acting force of the extension spring is stable and reliable, the service life is long, and the use requirement of the extension spring applied to the outside of the vehicle can be better met.
Fig. 4 is a schematic diagram of the operation of the wiper linkage shown in fig. 1 when the wiper motor is in a home position, in which the wiper arm and the wiper blade assembly are in a lower limit position, that is, the wiper arm and the wiper blade assembly are close to the lower edge of the windshield and can be started to swing upward at any time; fig. 4 shows the force F2 of the wiper motor on the second output crank at this time and the force Fk of the elastic element on the second output crank, where Fk ≧ 0.
Referring to fig. 4, in the first embodiment of the present invention, understandably, when the arm scraping blade assembly is at the lower limit position, the tension spring corresponding to this position is set to be in a natural state without elastic force, that is, Fk ═ 0 is set, so that the tension spring is not stressed for a long time to affect the performance or the service life, and the instantaneous acceleration of the arm scraping blade assembly at the lower limit position is not affected. It should be noted that, when the wiper arm assembly is at the lower limit position, the extending direction of the wiper arm assembly generally forms an included angle of 0 to 30 ° with the extending direction of the lower edge of the windshield, and the transverse curvature of the windshield is generally smaller, that is, the joint surface between the wiper arm assembly at the lower limit position and the windshield is more gentle, and the problem of larger instantaneous friction and instantaneous impact force due to too large instantaneous acceleration is less likely to occur. The instantaneous acceleration of the wiper arm blade assembly in the lower limit position may not be attenuated. Obviously, the design is not limited thereto, and in other embodiments, the elastic element 150 may be configured to apply an elastic force to the output crank when the wiper arm blade assembly is in the lower limit position, i.e., to set Fk > 0, according to actual needs, so as to reduce the instantaneous acceleration of the commutation of the wiper arm blade assembly in the lower limit position. In addition, in other embodiments, the elastic element may also be an elastic silicone body or an elastic rubber body.
Referring to fig. 2, in the first embodiment of the present invention, in order to improve the connection reliability between the extension spring and the output crank or the connecting rod, further, both ends of the extension spring are all provided with the hook portion 151, and the output crank and the connecting rod are all provided with the mounting hole for the hook portion 151 to movably penetrate. The arrangement that the bent hook portion 151 penetrates through the mounting hole can prevent the extension spring from being separated from the output crank or the connecting rod to cause the failure of the extension spring, and the mounting structure is simple and the mounting is convenient. However, the design is not limited to this, and in other embodiments, both ends of the extension spring may be provided with hook portions, both the output crank and the connecting rod corresponding to the hook portions are provided with screw mounting holes, and the hook portions are fastened together with the output crank and the connecting rod through screws.
Referring to fig. 2, in the first embodiment of the present invention, optionally, the two ends of the extension spring are further provided with winding portions 152, and the two winding portions 152 are respectively sleeved on the output crank and the connecting rod. Before the hook portion 151 is used for penetrating the mounting hole, the winding portion 152 is firstly used for winding one circle or two or more circles on the output crank or the connecting rod, so that the risk that the extension spring is separated from the output crank or the connecting rod can be further reduced.

The first connecting end and the second connecting end which are respectively arranged on the output shaft can enable the rain collecting plate of the vehicle to utilize the output shaft seat as a mounting point, the first connecting end and the main part structure of the wiper link mechanism 100 are hidden below the rain collecting plate, and only the second connecting end used for connecting the wiper arm and wiper blade assembly is exposed outside, so that the attractiveness of the vehicle can be improved, and the wiper link mechanism 100 can be protected to prolong the service life of the wiper arm and wiper link mechanism. However, the design is not limited thereto, and in other embodiments, one end of the output shaft may be connected to the output shaft seat, and the other end may be connected to the output crank and the wiper arm assembly.
Referring to fig. 1 and 2, in the first embodiment of the present invention, optionally, one end of the output crank is hinged to the connecting rod, the other end is connected to the output shaft, and the elastic element 150 is connected to the middle of the output crank. The elastic element 150 is connected to the middle part of the output crank, so that the installation space at the position can be well utilized, and the problem that the elastic element 150 interferes with surrounding parts in the stretching and restoring processes is avoided. In addition, because the elastic element 150 is connected with the middle part of the output crank, the length of the arm of force from the elastic acting moment of the elastic element 150 on the output crank to the output shaft is smaller than the length of the arm of force from the acting moment of the connecting rod on the output crank to the output shaft, so as to avoid the moment of force relative to the output shaft generated by the elastic acting force of the elastic element 150, and the moment of force relative to the output shaft generated by the acting force of the connecting rod which is excessively offset, so that the arm scraping and scraping blade assembly can not swing in a reversing way.
