The invention discloses a full width windscreen wiper of an automobile front window. The full width windscreen wiper of the automobile front window comprises an upper wiper, a lower wiper, rotating shafts and a driving motor, and the driving motor drives the upper wiper and the lower wiper to conduct cleaning operation through the rotating shafts. The full width windscreen wiper of the automobile front window is characterized in that the lower wiper comprises an elastic expansion device; the elastic expansion device comprises a slide-way board with a track and a spring, the lower wiper is movably connected with the rotating shafts, and one end of the lower wiper is pressed on the track of the slide-way board through the elastic force; a wiper arm of the lower wiper is provided with a radial channel, a sliding block is arranged in the radial channel and connected with the bottom end of the radial channel through the spring, and the rotating shafts are fixedly connected with the sliding block; the track is a concave groove and connected with the lower wiper through a roller. The full width windscreen wiper of the automobile front window has the advantages that the cleaning on dead angles of the automobile front windscreen is achieved, and requirements of various situations can be adapted through modifying the curve of the track in the slide-way board.
Description
Technical field
the present invention relates to a kind of vehicular spare parts, particularly a kind of car windscreen full width face wiper.
Background technology
traditional automobile wiper does the fan shape moving of standard usually, and shield glass is not the sector structure of standard, and for the Windshield of rectangle, the upper right corner is exactly the dead angle of rain brush motion, cannot reach.
china Patent No. is the patent of invention of " 200720148149.X ", disclose one " automatic telescopic automobile windshield wiper ", comprise rain brush and master cock, rain brush comprises windshield wiper handle, Wiper crank and Wiper head, master cock can control rain brush motion, also comprise rain brush telescopic control device, rain brush telescopic control device is located between windshield wiper handle and Wiper crank, and drives Wiper crank to stretch together with Wiper head by master cock control rain brush telescopic control device.Its total had both remained Windshield scrubbed by original rain brush motion when doing anticlockwise direction, fan shape moving, achieve again rain brush automatic telescopic in the clockwise direction, to complete the process of scrubbing Windshield dead angle, change the guide rail of respective shapes in adjustment after, the use needs of different model Windshield can be met, have structure adaptability strong, advantage simple, easy to use is installed.
above-mentioned patent realizes the scalable of rain brush by a series of device such as oil pump, oil cylinder, and cost is high, and control process is complicated.
in addition, because rotating shaft needs constantly positive anti-switching to rotate, too the use of the switching countershaft of rigidity is unfavorable, and the switching of rigidity also can bring noise and vibration.
secondly, rain brush is after blowing rain, if directly returned, the water dirt of carrying above waits foul can come back to again on Windshield, reduces the effect of rain brush.
therefore, need to improve existing windscreen wiper.
Summary of the invention
goal of the invention of the present invention is: for above-mentioned Problems existing, provides a kind of car windscreen full width face wiper.
the technical solution used in the present invention is such:
a kind of car windscreen full width face wiper, comprises rain brush, lower rain brush, rotating shaft and drive motor, and drive motor drives upper rain brush and lower rain brush to carry out clean operation by rotating shaft, it is characterized in that: lower rain brush also comprises elastic telescopic device.
further, described elastic telescopic device comprises chute board with track and spring, and lower rain brush is flexibly connected with rotating shaft, and one end of lower rain brush is pressed on the track of chute board by elastic force.
further, the Wiper arm of described lower rain brush is provided with radial channels, is provided with slide block in conduit, and slide block is connected by spring with the bottom of radial channels, and rotating shaft is fixedly connected with slide block.
further, described track is Baltimore groove, and lower rain brush is connected with Baltimore groove by roller.
further, in order to provide a buffering for rotating shaft, avoiding in the middle of excessively very stiff and demanding, described rotating shaft is one section of hard spring.
further, in order to make rain brush have an of short duration pause blowing in rain process, to facilitate the rainwater on rain brush to separate, described rotating shaft is engaged by partial gear with between drive motor.
further, described partial gear is preferably a pair, a responsible ascent stage job, and a responsible falling stage resets.
further, in order to keep rain brush to stop on the windshield attractive in appearance, described upper rain brush is " Z " font.
in sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
1, telescopic lower rain brush can clean the dead angle area in the Windshield upper right corner, and this technical scheme rational in infrastructure, cost is low, and reliability is high.And the needs of multiple situation can be adapted to by the curve of amendment chute board track.
, hard spring can provide certain buffering, avoids very stiff and demanding head-on collision during fault between mechanism element.
, partial gear provides the short stay of rain brush in operational process, the rainwater be convenient on rain brush is separated, and avoids returning Windshield.
, upper rain brush is set to " Z " font, lower rain brush is placed in below " Z " word turning, rain brush is stopped and becomes attractive in appearance, avoid affecting the visual effect on car front windshield.
Accompanying drawing explanation
fig. 1 is constructional drawing of the present invention.
fig. 2 is assembly drowing of the present invention.
fig. 3 is I partial enlarged view.
mark in figure: 1 is upper rain brush, and 2 is lower rain brush, 3 is rotating shaft, and 4 is chute board, and 5 is drive motor, and 6 is partial gear, and 21 is slide block, and 22 is coil tension spring, and 23 is roller, and 31 is hard spring.
Detailed description of the invention
below in conjunction with accompanying drawing, the present invention is described in detail.
