Detailed description of the invention

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.

The utility model provides a kind of single rocking arm windscreen wiper possessing two rocking arm function, as shown in Figure 2, this windscreen wiper is such as but not limited to being arranged on the front window of vehicle, it comprises wiper bracket 1, windscreen wiper rocking arm 2, swinging strut 3, windscreen wiper bar 4 and actuating unit (not shown), wherein, when the windscreen wiper in the utility model is arranged on front window, one end of windscreen wiper rocking arm 2 is positioned at the middle part of the lower window frame of front window, and connecting actuating unit, this actuating unit provides wiggly power to windscreen wiper rocking arm 2.The other end of windscreen wiper rocking arm 2 is provided with towards the bearing pin 21 of vehicle window.Swinging strut 3 is provided with the first axis hole 31, swinging strut 3 is set on the bearing pin 21 of windscreen wiper rocking arm 2 by this first axis hole 31, and can rotate around bearing pin 21, in order to prevent swinging strut 3 from deviating from bearing pin 21, be equipped with the locating part 22 limiting swinging strut 3 and shift out in the end head of bearing pin 21.

Above-mentioned windscreen wiper bar 4 is fixed on wiper bracket 1 towards on the end face of vehicle window, for sweeping the rainwater and dust etc. on vehicle window.Wiper bracket 1 preferably adopts rubber to make, on swinging strut 3, edge and the horizontal direction of vehicle window also offer the second axis hole 32, the axis of this second axis hole 32 and the axial vertical of the first axis hole 31, above-mentioned wiper bracket 1 realizes being connected with swinging strut 3 by second axis hole 32 of connecting element 5 through swinging strut 3, preferably, wiper bracket 1 is by being fixed with swinging strut 3 in the middle part of it, this kind of fixed form can with swinging strut 3 (i.e. the middle part of wiper bracket 1) for pivot point, make the two ends of wiper bracket 1 under the drive of swinging strut around this pivot point, glass is swept with more large-area.In addition, wiper bracket 1 can rotate towards vehicle window around connecting element 5, and the amplitude of this rotation is less, the windscreen wiper bar 4 be arranged on wiper bracket 1 can be made more to fit on glass, windscreen wiper bar 4 is swept totally.

As shown in Figure 3, because swinging strut 3 is connected with windscreen wiper rocking arm 2, when actuating unit is to windscreen wiper rocking arm 2 outputting power, windscreen wiper rocking arm 2 swings, and drive the wiper bracket 1 be connected with swinging strut 3 to swing, when the upper end 11 (with the top perpendicular to vehicle window for benchmark) of wiper bracket 1 swings, and (now between wiper bracket 1 and side window frame of automobile, there is certain angle when being resisted against the side window frame of vehicle window, namely the lower end 12 of wiper bracket 1 does not arrive and is resisted against on side window frame), wiper bracket 1 is subject to the barrier force from side window frame, and be applied on connected swinging strut 3, further, swinging strut 3 is because continuing to be subject to the application force that windscreen wiper rocking arm 2 continues swing, therefore rotate around bearing pin 21, and drive the lower end 12 of wiper bracket 1 to swing towards the side window frame of vehicle window, until wiper bracket 1 is upper, lower end 11, 12 are all resisted against on side window frame.Windscreen wiper in the utility model is compared with windscreen wiper of the prior art, the drive being subject to swinging strut 3 due to wiper bracket 1 can swing towards the edge of vehicle window further, therefore increase the sweep-out pattern of the windscreen wiper bar 4 be located on wiper bracket 1, achieve the maximization of sweep-out pattern, do not stay dead angle.

It should be noted that and the foregoing is only preferred embodiment of the present utility model, not thereby limit scope of patent protection of the present utility model, the utility model can also carry out the improvement of equivalence to the structure of above-mentioned various parts.Therefore the equivalent structure change that all utilizations specification sheets of the present utility model and diagramatic content are done, or directly or indirectly apply to other correlative technology fields and be all in like manner all included in the scope that the utility model contains.
