The specific embodiment
Is that example specifically describes the utility model below in conjunction with accompanying drawing with one of them windscreen wiper.
As shown in Figure 1, for the utility model proposes a kind of structural representation of telescoping wiper, comprise windscreen wiper arm 1, windscreen wiper sheet 2, first bar 31, second bar 32, the 3rd bar 33, the 4th bar 34, scalable windscreen wiper sheet 4, spring 5, rope 6, registration mast 8, in addition, motor and speed reduction gearing are not illustrated in the drawings.
Wherein, first bar 31, second bar 32, the 3rd bar 33 and the 4th bar 34 are formed four-bar linkage, four-bar linkage is the osed top parallelogram sturcutre, first bar 31 and the 3rd bar 33 are arranged in parallel, second bar 32 and the 4th bar 34 are arranged in parallel, second bar, 32 horizontal fixed are set, the point of connection of first bar 31 and second bar 32 is a run-on point 7, first bar 31 can be around run-on point 7 left-right rotation, windscreen wiper arm 1 is fixed on the run-on point 7, first bar 31 swings around the left-right rotation drive windscreen wiper arm 1 and the windscreen wiper sheet 2 of run-on point 7, realizes the cleaning to glass for vehicle window.
Scalable windscreen wiper sheet 4 is arranged in the windscreen wiper sheet 2, one end of scalable windscreen wiper sheet 4 is a free end, and the other end is connected with rope 6 with spring 5, under the effect of spring 5 and rope 6, the free end of scalable windscreen wiper sheet 4 can elongate or shorten with respect to windscreen wiper sheet 2, thereby enlarges the scope of wiper work.
One end of spring 5 is connected with scalable windscreen wiper sheet 4, and the other end is fixed in the windscreen wiper sheet 2; One end of rope 6 is connected with scalable windscreen wiper sheet 4, passes spring 5 successively, and windscreen wiper sheet 2 and windscreen wiper arm 1 inside stride across run-on point 7 and registration mast 8 and is fixed on the end points of first bar 31, and this end points is the intersection point of first bar 31 and the 4th bar 34.
If the angle that first bar 31 rotates around run-on point 7 is θ, when first bar 31 rotated the θ angle, corresponding windscreen wiper arm 1 and windscreen wiper sheet 2 were finished cycle of operations half, and promptly windscreen wiper arm 1 and windscreen wiper sheet 2 are finished the process from reference position to the maximum functional position.
Need to prove that in actual application, wiper is not limited to adopt above-mentioned four-bar linkage, in the four-bar linkage of other types, the scalable wiper that the utility model proposes can reach identical effect equally.
The principle of work of the telescoping wiper that the utility model proposes is:
When first bar 31 when shown position clockwise rotates, drive windscreen wiper arm 1 and windscreen wiper sheet 2 and do the cw swing from reference position, at this moment, rope 6 near first bar, 31 ends is under " pine " state, under the effect of spring 5, scalable windscreen wiper sheet 4 does to stretch out action, and along with the clockwise rotating of first bar 31, the extension elongation of scalable windscreen wiper sheet 4 is increasing; When first bar 31 turned to its angular bisector position, the extension elongation of scalable windscreen wiper sheet 4 reached maxim.When first bar 31 continues to clockwise rotate, windscreen wiper arm 1 and windscreen wiper sheet 2 continue to do the cw swing, at this moment, rope 6 near first bar, 31 ends is under " tightly " state, under about rope 6, scalable windscreen wiper sheet 4 is done the withdrawal action, and when first bar 31 reached the maximum rotation angle, scalable windscreen wiper sheet 4 was retracted to the initial position.When the maximum functional position turned back to reference position, scalable windscreen wiper sheet 4 experience were stretched out with under reach at windscreen wiper arm 1 and windscreen wiper sheet 2.
Therefore, in the wiper working process,, increase the work area of wiper by stretching out of scalable windscreen wiper sheet 4 with under reach.
Fig. 2 shows the work design sketch of telescoping wiper.As can be seen from the figure, by adopting telescoping windscreen wiper chip architecture, the wiper work area enlarges, and the working area of its actual increase is the area of dash area among the figure.
By the telescoping wiper of implementing the utility model proposes, increased the operating range of windscreen wiper, for driver in the car provides better visual range, and the safety and the driving experience of increase vehicle '.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
