The other end of the main short rod 9 is hinged to the main long rod 10 and is set on the frame 1 through the spindle C. Among them, the spindle C is fixedly set on the frame 1, and the main short rod 9 and the main long rod 10 are both matched with the spindle C through the sealed bearing. In addition, the position of the spindle C is in the middle and upper part of the frame 1, as shown in FIG. Figure 3 shown.

In addition, the position of the spindle D is in the middle and upper part of the frame 1, and is flush with the spindle C, the spindle C is on the left, and the spindle D is on the right.

[0034] The other end of the long connecting rod 16 and the other end of the auxiliary long connecting rod 17 are respectively hinged to the left end and the right end of the translation seat 18. Further, in order to increase the stability of the translation transmission component, a short rod 11 and a short transverse connecting rod 15 are added. Specifically, one end of the short rod 11 is hinged on the main long rod 10, and the other end of the short rod 11 is hinged on the long rod 12. One end of the short transverse connecting rod 15 is hinged on the long connecting rod 16, and the other end of the short transverse connecting rod 15 is hinged on the auxiliary long connecting rod 17, wherein the two ends of the short transverse connecting rod 15 are respectively hinged to the long connecting rod 16 and the auxiliary long connecting rod 17, but the position of the short transverse connecting rod 15 can be set according to the actual situation, and the short transverse connecting rod 15 only needs to be kept parallel to the short connecting rod 14, and the short transverse connecting rod 15 can also be removed.

[0035] From the above, it can be known that the main long rod 10 and the long connecting rod 16 are hinged through a rotating shaft and their hinge point is set to E; the auxiliary long connecting rod 17 and the auxiliary long rod 13 are hinged through a rotating shaft and their hinge point is set to F; the long rod 12, the short connecting rod 14 and the long connecting rod 16 are hinged through a rotating shaft and their hinge point is set to G; the short connecting rod 14 and the auxiliary long connecting rod 17 are hinged through a rotating shaft and their hinge point is set to H; the left end of the long connecting rod 16 and the translation seat 18 is hinged through a rotating shaft and its hinge point is set to I; the right end of the auxiliary long connecting rod 17 and the translation seat 19 is hinged through a rotating shaft and its hinge point is set to J; the main long rod 10 and the upper push-pull rod 8 are hinged through a rotating shaft and their hinge point is set to K; the main short rod 9 and the lower push-pull rod 7 are hinged through a rotating shaft and their hinge point is set to L.

[0036] Therefore, C, E, G, L form a parallelogram CEGL, where the rod length CE = GL, CL = EG; G, I, J, H form a parallelogram GIJH, where the rod length GI = JH, GH = IJ; C, D, E, F form a parallelogram CDEF, where the rod length CE = DF, CD = EF, and EF = GH. Parallelogram CEGL, parallelogram GIJH and parallelogram CDEF form a parallelogram series-parallel mechanism.

[0037] The length of the short rod 11 is equal to that of the EG rod, and the short rod 11 is arranged at the midpoint or non-midpoint of the long side CE of the parallelogram CEGL; in this embodiment, the short rod 11 is arranged at the midpoint of the long side CE of the parallelogram CEGL, and the short rod 11 is parallel to the short side EG. The length of the short horizontal connecting rod 15 is equal to that of the GH rod, and the short horizontal connecting rod 15 is parallel to the GH.

[0038] Further, the rod length CK=CL, wherein CK and the long side CE of the parallelogram CEGL are the same component and may be collinear or not; in the present embodiment, CK and the long side CE of the parallelogram CEGL are the same component and may be collinear; CL and the short side CL of the parallelogram CEGL are the same component and may be collinear or not and be equal in length or unequal in length; in the present embodiment, CL and the short side CL of the parallelogram CEGL are the same component and are collinear and equal in length to each other.

[0039] Further, the rod lengths of the lower push-pull rod 7 and the upper push-pull rod 8 are equal. The rotation axis between the lower push-pull rod 7 and the rocker 6 and the rotation axis between the upper push-pull rod 8 and the rocker 6 are coaxial or non-coaxial. In this embodiment, the rotation axis between the lower push-pull rod 7 and the rocker 6 and the rotation axis between the upper push-pull rod 8 and the rocker 6 are coaxial, and the rods at the same hinge point are also coaxial.

[0040] like Figure 4As shown, the rotating shaft that realizes the hinged connection of the above-mentioned rods is equipped with a rotating shaft sealing structure, wherein the rotating shaft sealing structure can adopt a single seal or a composite seal. In this embodiment, the rotating shaft sealing structure includes a support ring, a gasket, an O-ring and an oil seal TC; wherein the support ring is arranged at the end of each rod or on the rod after being sleeved with the rotating shaft, and then a gasket and an O-ring are arranged between the coaxial rods, and a gasket and an O-ring are sleeved at the end of the rotating shaft, and finally sealed by the oil seal TC. In addition to the structure described in this embodiment, structures that can realize the sealing of the rotating shaft belong to the protection scope of the present invention, for example, the rotating shaft sealing structure can also be selected as a sealed bearing.

[0041] like Figure 6 and 7 As shown, the translation seat 18 is connected to the scraper 19 through a guide rod, the plane where the guide rod is located is parallel to the plane where the scraper 19 is located, and the plane where the guide rod is located is parallel to or forms an angle with the plane where the translation seat 18 is located; in this embodiment, the plane where the guide rod is located is parallel to the plane where the translation seat 18 is located. The angle formed by the plane where the guide rod is located and the plane where the translation seat 18 is located enables the scraper 19 to wipe the inclined glass.

[0042] The working process of the present invention will be further described below:

[0043] The reduction motor 3 is connected to the control box of the window scraper system. The output shaft A of the reduction motor 3 drives the crank 4 connected thereto to rotate continuously in one direction, and through the action of the connecting rod 5, the rocker 6 is pushed to swing around the spindle B.

[0044] Then, the main long rod 10 and the main short rod 9 are driven to swing around the central axis C through the lower push-pull rod 7 and the upper push-pull rod 8;

[0045] Thus, the short rod 11, the long rod 12, the auxiliary long rod 13, the short connecting rod 14, the short horizontal connecting rod 15, the long connecting rod 16, and the auxiliary long connecting rod 17 in the three series-parallel parallelograms CEGL, GIJH, and CDEF are driven to swing under the support of the spindle D on the frame 1;

[0046] When the long sides of the three parallelograms CEGL, GIJH, and CDEF are all equal, the translation seat 18 reciprocates along a straight line to drive the scraper 19 to translate and brush the window;

[0047] When the long sides of parallelograms CEGL and CDEF are equal but the long side of parallelogram GIJH is slightly larger or smaller than the long side according to design requirements, the translation seat 18 reciprocates along two equal micro-arc lines to drive the scraper to move horizontally.

[0048] The whole product can be installed above or below the glass window with the frame 1. Figure 1 As shown, the two extreme positions of the swing of the rocker 6 correspond to the extreme positions of the scraper 19 at the two window edges.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
