Special vehicle omniscope Wiper system
Technical field
The utility model relates to a kind of special vehicle omniscope Wiper system.
Background technology
At present, special vehicle is observed the main omniscope that relies in car, and because the practical service environment of special vehicle is severe, in driving process, silt or dust can be attached on omniscope glass surface, affect sight line and observing effect.
Summary of the invention
In order to overcome the easy contaminated deficiency of existing omniscope, the utility model provides a kind of Wiper system, omniscope is carried out to wiper, all brush configurations of scraping are all outside car, do not take interior space, be communicated with car internal controller by socket through walls, controlled by car internal controller, solved the current omniscope problem that affects sight line that brush device causes that do not rain.
The utility model is realized by following technical scheme:
A kind of special vehicle omniscope Wiper system, comprise gear case, scraping arm, dust boot, rain brush guard shield, reducing motor, universal-joint, brushing piece, leading screw, feed rod, brush holder, bearing and guide rail, the rain brush guard shield that omniscope is covered is fixed on car body, above-mentioned remaining part is contained in rain brush guard shield, wherein, guide rail, gear case and reducing motor are all fixed on rain brush guard shield, rain brush guard shield is towards direction of traffic opening, reducing motor lead-in wire connects car internal controller, reducing motor is connected to gear case through universal-joint, the finishing bevel gear cuter for commutating of pair of meshing is housed in gear case, one of them output bevel gear drives leading screw rotation, brush holder is arranged on leading screw and feed rod, dust boot surrounds leading screw and feed rod, brush holder is arranged on by the bearing of its upper end in the groove of guide rail, brushing piece to omniscope minute surface wiper is connected on scraping arm, scraping arm is connected on brush holder.
On brush holder, with magnet steel, guide rail two ends are provided with Hall switch, and Hall switch is connected with car internal controller, can give controller feedback signal control reducing motor stall or reversion.
The cover plate that rain brush guard shield opening can be covered tightly or opens is housed on rain brush guard shield.
Rain brush guard shield both sides are provided with the locking pin that cover plate can be fixed on to the state of opening or closing.
The utility model can rely in car and control, and omniscope minute surface is cleaned, and do not change car body inner structure.

Detailed description of the invention
The utility model is in gun commander's gun sight outside, increase one deck steel guard shield, guard shield is directly fixed on car body, on steel guard shield, lay guide rail and motor, motor is passed to leading screw by torsion after drop-gear box slows down, drive slide block to move reciprocatingly on guide rail by leading screw, drive brushing piece to carry out wiper to minute surface.
As shown in Figure 1 and Figure 2, the utility model comprises gear case 1.1, scraping arm 1.2, dust boot 1.3, rain brush guard shield 1.4, locking pin 1.5, cover plate 1.6, hinge pin 1.7, reducing motor 2.1, universal-joint 2.2, brushing piece 2.3, leading screw 2.4, feed rod 2.5, brush holder 2.6, bearing 2.7, guide rail 2.8 and Hall switch 2.9.
Reducing motor 2.1 lead-in wires connect car internal controller, rotated by controller control reducing motor 2.1, reducing motor 2.1 is connected to gear case 1.1 through universal-joint 2.2, after gear case 1.1 internal bevel gear commutations, drive leading screw 2.4 to rotate, leading screw 2.4 rotarily drives brush holder 2.6 and moves along feed rod 2.5 directions.Bearing 2.7 on brush holder 2.6 slides in guide rail 2.8 grooves.Dust boot 1.3 surrounds leading screw 2.4 and feed rod 2.5, shields.Brushing piece 2.3 is connected on scraping arm 1.2, with brush holder 2.6 crank motions, realizes the wiper to minute surface.On brush holder 2.6, with magnet steel, in the time that brush holder 2.6 moves to Hall switch 2.9 place along guide rail 2.8, feed back signal to car internal controller, by 2.1 stalls of controller control reducing motor or reversion.
Guide rail 2.8, gear case 1.1 and reducing motor 2.1 are all fixed on rain brush guard shield 1.4, on rain brush guard shield 1.4, there is cover plate 1.6, can wrap leaf pin 1.7 and rotate, cover tightly or open, there is locking pin 1.5 rain brush guard shield 1.4 both sides, cover plate 1.6 can be fixed on to the state of opening or closing.
