Glass regulator
Technical field
The utility model relates to a kind of glass regulator.
Background technology
Window regulator on the car adopts cable pulley type mostly at present.The shortcoming of cable pulley type lifter is higher to the conditional request of associated components: to having relatively high expectations of associated components such as glass and glass guide-rail, structure is complicated.The productive costs height costs an arm and a leg, and drag-line is broken easily, and et out of order often needs repairing easily, and service life is short.
Summary of the invention
The claimed technical scheme of the utility model provides a kind of glass regulator simple in structure, long-lived.
The technical solution of the utility model is as follows: a kind of glass regulator, comprise motor, rotate tooth plate, lifting arm, pivot pin, fixed arm, equilibrium arm, long guideway, lifting arm is fixed on the pivot pin and can rotates around pivot pin, lifting arm one end is fixed with can be by motor-driven rotation tooth plate, the other end is stuck in the long guideway by pulley, also have on the lifting arm by the fixing equilibrium arm of axis, equilibrium arm can rotate around axis, one end of equilibrium arm is stuck in the long guideway by pulley, and the other end is stuck in the fixed arm parallel with long guideway by pulley.
The utility model has obvious improvement compared with prior art: the utility model is a wishbone glass lifter, and structure and mode of motion are simpler, can reduce the fault rate of jacking system, reduces use, service expenditure.There is not the easily broken wire drawing in cable pulley type lifter Shen because of wishbone glass lifter simultaneously, can improves the service life of window regulator significantly.Compare the cable pulley type lifter, to glass and associated components require lessly, can in wider scope, use.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
The specific embodiment
As shown in Figure 1, glass regulator comprises motor 1, rotates tooth plate 2, lifting arm 3, pivot pin 4, fixed arm 5, equilibrium arm 6, long guideway 7, lifting arm 3 is fixed on the pivot pin 4 and can rotates around pivot pin, lifting arm one end is fixed with can be by the rotation tooth plate 2 of motor 1 driving, the other end is stuck in the long guideway 7 by pulley 8, also have on the lifting arm by the fixing equilibrium arm 6 of axis, equilibrium arm can rotate around axis, one end of equilibrium arm 6 is stuck in the long guideway by pulley 8, and the other end is stuck in the fixed arm parallel with long guideway 5 by pulley 8.In the utility model, lifter has adopted the fork arm type equal lifter.In use, the motor of window regulator is fixed on the support, and support is fixed on the interior panel beating, and fixed arm is horizontally fixed on the panel beating, and glass passes through two screw retention on the long guideway assembly of lifter.By the rotation of motor, drive and rotate the tooth plate rotation, make lifting arm center on pivot pin and do forward, the contrarotation certain angle; Equilibrium arm is that run-on point is rotated with the axis simultaneously, and pulley assembly is made back and forth movement in fixed arm and long guideway assembly, the long guideway assembly is moved up and down, and realizes the glass lifting function.
