detailed description

As shown in Figure 1, a new type of automobile wiper is located on the outside of the windshield of the automobile, including a wiper blade 1, a wiper rod and a first motor 2 for driving the wiper rod to reciprocate, and the wiper rod Including the sleeve rod 3, the linear rack bar 4 and the first cross bar 5, the sleeve rod 3 is a hollow structure, and the bottom end of the sleeve rod 3 is connected to the first motor 2, and the linear rack bar 4 is sleeved on the sleeve rod 3 Inside, a gear 6 meshing with the linear rack bar 4 and a second motor 7 that drives the gear 6 to rotate are respectively provided on the upper part of the sleeve rod 3, and a slider 8 is also provided at the bottom end of the linear rack bar 4. Both sides of the sleeve rod 3 are respectively provided with slide grooves (not shown in the figure) for embedding the slider 8, and at the same time, an upper limit block is also provided on the upper part of the sleeve rod 3 below the second motor 7. 9. There is also a lower limit block 10 at the bottom of the sleeve rod 3, the top of the linear rack bar 4 is connected to the right end of the first cross bar 5, and the left end of the first cross bar 5 is also connected to the top of the wiper blade 1 connect.

Specifically, for the above-mentioned new type of automobile wiper, wherein the second motor 7 is a micro motor.

By adopting the above-mentioned structure, when the wiper performs a wiping operation, the sleeve rod 3 and the linear rack bar 4 are driven by the first motor 2 to reciprocate, and then the linear rack bar 4 drives the wiper blade 1 on the windshield of the car. Wiper up and down reciprocally, so that rain, snow and dust on the windshield of the car can be removed in time in rainy and snowy weather; when the wiping range or area of the wiper blade 1 is to be adjusted, the gear can be driven by the second motor 7 6 rotates, and then the gear 6 drives the linear rack bar 4 to move along the length direction of the sleeve rod 3, or to extend to the outside of the sleeve rod 3, thereby expanding the wiping range upward, or to extend to the inside of the sleeve rod 3, to Extend the wiping range down. At the same time, by setting the slider 8 and the chute structure, the smooth linear movement of the linear rack bar 4 in the sleeve rod 3 can be more effectively guaranteed, and the linear rack can be constrained by the upper limit block 9 and the lower limit block 10. The rod 4 and the slider 8 move between the highest position and the lowest position. In this way, by flexibly adjusting the relative position between the linear rack bar 4 and the sleeve bar 3, the wiper blade 1 can wipe the area or range that has not been touched before, so that the wiping range is greatly expanded at last. This greatly improves the driver's field of vision and ensures driving safety.

As a preference, for the above-mentioned novel automobile wiper blade, the length of the wiper blade 1 is equal to the length of the sleeve rod 3 . In this way, when the linear rack bar 4 is lowered to the lowest position, it can ensure that the bottom end of the wiper blade 1 can extend to the lower edge of the windshield, thereby further helping to eliminate the dead angle of wiping and ensure the wiping effect.

As a further preference, in the above-mentioned novel automobile wiper, the first cross bar 5 and the linear rack bar 4 are hinged, and the wiper blade 1 and the first cross bar 5 are also hinged. Both of the above two connection positions are set as hinges, which not only can flexibly adjust the position of the wiper blade 1 relative to the linear rack bar, but also can flexibly adjust the gap distance between the wiper blade 1 and the windshield, thereby realizing flexible Adjust the pressing force of the wiper blade 1 on the windshield. In addition, through the hinged structure, the angle between the wiper blade 1 and the windshield can be flexibly adjusted to ensure that the wiper blade 1 can always be in contact with the windshield at the maximum The area is tightly attached to the windshield (even for different models), thus further ensuring an effective wiping area and a good wiping effect.

As a further preference, for the above-mentioned novel automobile wiper, wherein the first cross bar 5 is also a hollow structure, and the left end in the first cross bar 5 is also provided with Range sensor 11 for distance between edges. In this way, the position range of the wiper blade 1 on the windshield can be sensed in real time, which further facilitates the flexible adjustment of the linear rack bar and the first cross bar.

In summary, by adopting the above structure, the utility model can flexibly adjust the structure of the wiper, and effectively expand the wiping range, thereby greatly improving the driver's field of vision and driving safety.

Above in conjunction with the accompanying drawings, the preferred specific implementations and examples of the present utility model have been described in detail, but the present utility model is not limited to the above-mentioned implementations and examples, within the scope of knowledge possessed by those skilled in the art, it can also be Various changes are made under the premise of breaking away from the utility model design.
