Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
As shown in Figure 2, Windscreen wiper structure for automobile of the present invention, comprising: the first motor 1, second motor 2, Wiper arm 3, Wiper crank 4 and Wiper blade; First motor 1 is fixedly mounted on vehicular meter front edge of board; One end of Wiper arm 3 is connected with the rotating shaft of the first motor 1, and the other end is connected with the rotating shaft of Wiper crank 4; Second motor 2 is arranged on the middle part of Wiper crank 4; Wiper blade is socketed in Wiper crank 4 surface relative with Windshield, comprises fixed plate 5 and movable plate 6; Movable plate 6 and the second motor 2 sliding block joint.Windscreen wiper structure for automobile of the present invention, on the basis ensureing Wiper structure bulk strength, by Wiper blade being changed into fixed plate 5 and movable plate 6, and increase the second motor 2 control movable plate 6 relatively Wiper blade do horizontal slip, be the C-C direction motion shown in Fig. 2; In addition Wiper arm 3 and Wiper crank 4 connection are arranged rotating shaft, make the relative Wiper arm 3 of Wiper crank 4 can do longitudinal swing, be the B-B direction motion shown in Fig. 2; Utilize the lateral shuttle that in original Wiper structure, Wiper arm 4 is undertaken by the first motor 1 to swing simultaneously, be the A-A direction motion shown in Fig. 2; Can clean thoroughly Windshield in three directions.Wherein Wiper arm 3 carries out lateral shuttle by the first motor 1 and swings and can remove attachment dust on the windshield and rainwater, and the slip of movable plate 6 matches with the swing of Wiper crank 4, then can remove the foreign matter that attachment mosquito corpse on the windshield and dry mud etc. are difficult to remove, thus make vehicle run at high speed or in harsh environment, also can ensure that chaufeur has the open and travel safety of visual field raising clearly.
As shown in Figure 3, the surperficial lateral axis that Wiper blade is relative with Windshield is provided with sliding guide groove 7, and movable plate 6 is socketed in described sliding guide groove 7.As can be seen from the system of axes in Fig. 3, the lateral axis on Wiper blade surface is X axis, the surperficial lateral axis that sliding guide groove 7 is arranged on Wiper blade is conducive to the stability of movable plate 6 when sliding and balance, the obstinate foreign matter strengthened on movable plate 6 pairs of Windshield is removed further.The structure of sliding guide groove 7 plays very important effect for the smooth and easy slip of movable plate 6, when sliding guide groove 7 be I-shape guide groove or T-shaped guide groove time, because the movable plate 6 being positioned at sliding guide groove 7 is more, utilize I-shape guide groove and T-shaped guide groove good stability, characteristic that intensity is high simultaneously, movable plate 6 can be made to be not easy to produce fracture in slip, thus to improve the cleaning efficiency of movable plate 6.And when sliding guide groove 7 be square guide groove or trapezoidal guide groove time, because the structure of sliding guide groove 7 is relatively simple, movable plate 6 is relative with the contact surface of sliding guide groove 7 less, the friction that can take in sail between sheet 6 and sliding guide groove 7, improve the lubricity of movable plate 6, make movable plate 6 that higher sliding velocity can be utilized to remove the obstinate foreign matter on Windshield.According to the difference of different automobile types to clean requirement, the structure of sliding guide groove 7 can be selected in a particular application.In addition, preferably a sliding guide groove 7 carries out coordinating with a slice movable plate 6 the obstinate foreign matter removed on Windshield in this patent, and in the large or more muddy area of dust storm, also can match with multi-disc movable plate 6 by arranging many sliding guide grooves 7, the cleaning efficiency of further enhancing rain brush, does not limit in embodiments of the present invention.
It can also be seen that from Fig. 3, the cross-sectional plane of movable plate 6 is triangle or trapezoidal, simultaneously the zig-zag that arranges for longitudinal interval of movable plate 6, and its to connect in sliding guide groove 7 be an entirety.Can be learnt by the system of axes in Fig. 3, the cross-sectional plane of movable plate 6 is Y-axis cross section, when the cross-sectional plane of movable plate 6 be triangle or trapezoidal time, triangle or trapezoidal behavior of structure can be utilized, movable plate 6 is deposited in two sides by X axis the removed obstinate foreign matter that slides, and by the longitudinal oscillation of Wiper crank 4 by the edge of foreign bodies removal to Windshield, the cleaning efficiency of movable plate 6 can be improved.In addition, movable plate 6 is spaced zig-zag in the shape of X axis, utilizes that zig-zag friction force is strong, positive pressure is large on contact surface characteristic, the round slip of obstinate foreign matter by movable plate 6 progressively can be removed.And movable plate 6 to connect in sliding guide groove 7 be the bulk strength that an entirety can increase movable plate 6, increase the service life of movable plate 6.Certainly, the cross-sectional plane of movable plate 6 also can adopt V-shaped groove or W shape groove etc. to increase the structure of friction force further, does not limit in embodiments of the present invention.
As shown in Figure 3, fixed plate 5 is arranged on the both sides of movable plate 6; The surface that fixed plate 5 is relative with Windshield with Wiper blade is connected; And the cross-sectional plane of fixed plate 5 is triangle or trapezoidal.Fixed plate 5 is arranged on the both sides of movable plate 6; not only can form protective effect to movable plate 6; but also can in advance the dust on Windshield or rainwater be cleaned with water totally; movable plate 6 can be removed obstinate foreign matter specially; breakage can not be caused because of the corrosion of dust or rainwater, increase the service life of movable plate 6.In the manufacturing process of Wiper blade, fixed plate 5 and Wiper blade are formed in one structure, so not only can reduce the operation of processing, and can save cost.The cross-sectional plane of fixed plate 5 is identical with the cross-sectional plane of movable plate 6, is Y-axis cross section, and preferably the shape of cross section of fixed plate 5 and movable plate 6 is triangle or trapezoidal in the present invention, mainly for reducing processing mold, saves cost.The shape of cross section of fixed plate 5 can be identical with movable plate 6, also can be different according to the shape of cross section of concrete needs and movable plate 6, do not limit in embodiments of the present invention.
As shown in Figures 2 and 3, fixed plate 5 dorsad movable plate 6 and Wiper blade connection stretches out and forms bead 8, and Wiper blade is socketed in Wiper crank 4 by the bead 8 of both sides.Utilize bead 8 to be arranged in Wiper crank 4 by Wiper blade socket easily, not only easily keep in repair and change Wiper blade, the manufacturing cost of Wiper blade can also be saved simultaneously.Additionally by being connected of bead 8 and Wiper crank 4, the bulk strength of Wiper structure can also be strengthened, can be more stable when making movable plate 6 carry out clean, improve cleaning efficiency and the service life of rain brush.
Although the present invention is described in conjunction with above embodiment, but the present invention is not limited to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present invention and scope.
