Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
As shown in Figure 1, the two rain brush wipers of one in the utility model embodiment, comprise left rain brush 1 and right rain brush 2, for the actuating device that drives left rain brush 1 and right rain brush 2 to move reciprocatingly, this actuating device comprises drive wheel 3 and transmission body 4, drive wheel 3 is positioned at the center of the framework that transmission body 4 forms, the edge of drive wheel 3 is provided with driving gear 5, the two ends up and down of transmission body 4 are provided with the tooth bar 6 matching with driving gear 5, drive wheel 3 is positioned at the center of two tooth bars 6, and drive wheel 3 just contacts with the tooth top portion of tooth bar 6 without the edge of driving gear 5, only have in the time that driving gear 5 engages with gear 6, drive wheel 3 could drive transmission body 4 to move, left like this rain brush 1 and right rain brush 2 move to after the boundary position of vehicle window, can pause the regular hour, then just reciprocating, avoided rain brush moving always, improve the service life of rain brush.Preferably, be provided with pilot bar 8 at the two ends, left and right of transmission body 4, be provided with guide fixed block 9 with pilot bar 8 corresponding positions, to coordinate the linear reciprocating motion of transmission body 4.
One end of left rain brush 1 and right rain brush 2 is hinged on respectively the upper end of transmission body 4, be provided with the bearing 7 for being rotationally connected left rain brush 1 and right rain brush 2 near hinged place, like this, under the drive of transmission body 4, can realize the reciprocal cleaning action of left rain brush 1 and right rain brush 2.As shown in Figures 2 and 3, the vertical joint pin 10 that stretches out in one end that left rain brush 1 is hinged on transmission body 4 with right rain brush 2, the end of joint pin 10 is formed with and has elastomeric protruding 11, accordingly, the upper end of transmission body 4 is provided with several through holes 13 (seeing Fig. 1) matching with joint pin 10, because projection 11 has elasticity, when installing or dismantling, pressing projection 11 inserts through hole 13 or extracts from through hole 13, preferably, on joint pin 10, be arranged with spring 12, make left rain brush 1 and right rain brush 2 more stable with being connected of transmission body 4.
