As a preferable scheme of the present invention, the driving device includes a worm gear reducer fixed on the fixing base, and a motor drives the worm gear reducer.

As a preferable scheme of the invention, the worm gear reducer is linked with a crank, and the free end of the crank is rotationally connected with a first connecting rod in a crank connecting rod assembly.

As a preferable scheme of the invention, the free end of the first connecting rod is rotatably connected with the rocker.

As a preferred scheme of the invention, the free end of the rocker is rotatably sleeved on a fixed column fixed on the vertical plate of the fixed seat.

In a preferred embodiment of the present invention, a second link is fixed to a free end of the rocker, and the second link extends toward the driving device.

Preferably, the connecting assembly includes a third link connected to the free end of the second link by a spring shaft.

As a preferable scheme of the invention, the spring shaft comprises a vertically placed rotating shaft, and a spring matched with the third connecting rod and the second connecting rod is sleeved on the rotating shaft.

In a preferred embodiment of the present invention, a wiper blade is fixed to a free end of the third link.

As a preferred embodiment of the present invention, the wiper blade includes a connecting seat having a middle portion and a third link, and a hanging plate portion extending outward from both sides of the connecting seat.

Advantageous effects

The automobile windscreen wiper comprises a fixed seat, wherein the fixed seat is connected with a crank connecting rod assembly through a driving device, a rocker of the crank connecting rod assembly is linked with a second connecting rod, and the second connecting rod is connected with a windscreen wiper plate which can move along with the shape of glass through a connecting assembly. The invention provides a wiper structure which is different from the wiper structure in the prior art, and the wiper structure is better attached to glass and better in wiping action through the structure.
