Summary of the invention
The purpose of this utility model is to provide a kind of that brushless direct current motor drives, cost and relatively low, reliable electronic windshield wiper of energy consumption of adopting.
The purpose of this utility model is achieved through the following technical solutions: it comprises the motor that is installed in the power transmission-gear box and speed-changing mechanism, connecting rod wabble mechanism, the brushing machine that joins with the rocking bar of connecting rod wabble mechanism and the electric-controlled box that is connected with motor, it is characterized in that: drive motor 12 adopts the brushless slotless permanent magnet direct current motor, the power take-off shaft of drive motor 12 joins by worm and gear speed-changing mechanism 10 and connecting rod wabble mechanism, and brushing machine is sleeved on the balance staff 11 of connecting rod rocker mechanism; Drive motor 12, worm and gear speed-changing mechanism 10, connecting rod wabble mechanism, cooperate the electric-controlled box 5 that is connected and clean the reset attachment engage sleeves with water with motor and be contained in the power speed changing casing 8, many gears change-over swith of electric-controlled box 5 is packed on the outer wall of power speed changing casing 8.The pivoted arm 1 of connecting rod wabble mechanism and the outer end of swing arm 4 are hinged with the two ends of connecting rod 2 respectively, are set with miniature double-row bearing 3 in the hinge hole at connecting rod 2 two ends.Clean reset attachment with water and adopt the magnetic reposition element, it is made up of magnet 21 and dry-reed tube 19, and magnet 21 is packed on the connecting rod 2, and dry-reed tube 19 installs the position and matches with magnet 21 and connecting rod 2.One of specific embodiment that reset attachment is installed is: magnet 21 is packed on the right-hand member of connecting rod 2, and dry-reed tube 19 matches with magnet 21 and connecting rod 2 and is packed on the automatically controlled plate 20 on swing arm 4 right sides.
Drive motor of the present utility model adopts the brushless slotless permanent magnet DC motor, thereby saved carbon brush wearing and tearing hidden danger, make whole device operation more reliable, bearing set in the rod hinge connection hole of its connecting rod wabble mechanism, thus further improve the stationarity of link work and reduced energy consumption.Clean reset attachment with water and adopt the magnetic reposition element, thereby avoided the defective damaged because of contact wear with the contact reset attachment, prolonged the service life of cleaning reset attachment with water widely.Simultaneously motor, speed-changing mechanism, electrical controller, connecting rod wabble mechanism etc. are installed in the small box body, have constituted the rain system of blowing of electromechanical.
Description of drawings
Fig. 1 is a main TV structure scheme drawing of the present utility model;
Fig. 2 is Fig. 1 vertical profile structural representation;
Fig. 3 is the cross-sectional structural representation of Fig. 1;
Fig. 4 is a reset attachment structural representation of the present utility model.
The specific embodiment
By Fig. 1 to Fig. 4 as can be known, the power take-off shaft of drive motor 12 joins by worm and gear speed-changing mechanism 10 and connecting rod wabble mechanism, and brushing machine is sleeved on the balance staff 11 of connecting rod rocker mechanism.The pivoted arm 1 of connecting rod wabble mechanism and the outer end of swing arm 4 are set in the hinge hole at connecting rod 2 two ends by affixed rotating shaft on it, the miniature double-row bearing 3 of suit in the rotating shaft in the hinge hole at connecting rod 2 two ends, thereby make pivoted arm 1 and swing arm 4 and connecting rod 2 smooth motion more, reduce the wearing and tearing of resistance and rotating shaft, improved the stationarity and the service life of mechanism's work.Cleaning reset attachment with water is made up of magnet 21 and dry-reed tube 19, magnet 21 is packed in the right-hand member upside of connecting rod 2, dry-reed tube 19 matches with magnet 21 and connecting rod 2 and is packed on the automatically controlled plate 20 on swing arm 4 right sides, when moving right, connecting rod 2 can not run into dry-reed tube 19, but can not be too far away from getting, it do not have wearing and tearing, thereby greatly prolongs its service life by magnetic control.
The specific embodiment is: the utility model is installed in the top that the locomotive cab front window is inspected glass, energized, when the many gears change-over swith that is packed in the apparent electric-controlled box of power box is transferred to " startup " shelves, the master cock K closure of the dry-reed tube 19 of reset attachment is connected whole electrical control circuit, the motor rotation, the utility model is in treats mode of operation.
When many driving switch transfer to " at a slow speed " shelves, drive motor 12 relative slow rotation then, its outputting power is after the worm and gear speed-changing mechanism changes transmission direction and slows down, improved driving torque, and drivening rod wabble mechanism waggle, thereby the brushing machine that drives on the output rocking bar 11 that is installed in the connecting rod wabble mechanism swings back and forth at a slow speed.In like manner, when many driving switch transfer to " fast " when shelves, drive motor 12 relative twirl then, the brushing machine on the drive rocking bar 11 swings back and forth fast.Brushing machine swings back and forth in the process, and it influences the accumulation of the obstacles such as external rainwater, snowflake, mist illiteracy of driver operation sight line during handler garage advances effectively.
When many driving switch transfer to " stopping " shelves, the master cock K of the dry-reed tube 19 of reset attachment disconnects, because dry-reed tube 19 do not disconnect, motor continues rotation, when motor rotates the magnet that makes on the connecting rod 2 21 near dry-reed tube 19, dry-reed tube 19 also cuts off the power supply, thereby entire circuit is disconnected, and motor stops the rotation, and brushing machine stops to swing back and forth, this moment, rain brush just in time leaned against on the position that does not keep off pilot's line of vision, reached the purpose that resets.
Driving motor of the present utility model has adopted brushless slotless DC (110V80W) electrical motor first; Adopt the connecting rod mechanism of miniature bearing first, improved the swing attitude of the water brush arm back of the body, improved service life; Clean reset attachment with water and adopted the magnetic reposition element first, prolonged service life better.
The utility model also can adopt many grades of change-overs swith, will start, at a slow speed, fast, stop and the fourth gear stepwise operation that automatically resets is finished continuously, easy to operate, also can adopt the infinite speed variation control setup, realize the infinite speed variation of fork.Brushing machine can be common Wiper blade type, also can adopt band to drench Wiper blade type structure or other structure of spray.
