Abstract

The utility model discloses a glass lifter for an automobile. The glass liter comprises a driving arm, an assistant arm, a stationary guide rail, a moveable guide rail, an arc-shaped toothed plate and a spline and a bottom plate which are engaged with the arc-shaped toothed plate, wherein the arc-shaped toothed plate comprises a fixed part fixed with the driving arm and a rack part slidingly arranged on the fixed part. According to the lifter provided by the utility model, when glass descends to a lower limit position, if a motor continuously outputs powder, the spline drives the rack part to slide on the fixed part (the driving arm does not continue to rotate), so that the motor is not locked, and therefore, damage to the motor and the toothed plate is reduced.

Description

Automobile glass lifter

Technical field

The utility model relates to the lifting gear on the vehicle glass.

Background technology

Automobile glass lifter refers to by motor or manual drives, and by transmission mechanism automobile window glass risen or descends along the glass gathering sill, and can rest on the device of optional position on request.

General to intersect arm-type lifter mainly be to be driven by direct current generator, by motor internal gear, outside driving toothed plate and by master arm, decide the motion of the four-bar mechanism that guide rail, auxiliary form, makes the glass for vehicle window rising or drop to a kind of device that needs the position.Its structure mainly is made up of metallic stamping pieces, and two stamping parts master arms and auxiliary that its cardinal principle is used gear shaft motor-driven tooth plate to drive to intersect realize moving up and down (operating principle that is similar to the scissors crossing arm).In use, the motor of glass-frame riser is fixed on the support, and support is fixed on the interior panel beating, decides guide rail and is horizontally fixed on the panel beating, and glass is fixed on the moving rail assembly of lifter by two screws.By the rotation of motor, drive and rotate the tooth plate rotation, make auxiliary center on pivot pin and do forward, the reverse rotation certain angle; Simultaneously master arm is run-on point with the axis, pulley assembly decide guide rail and long lead to kneel make back and forth movement in the assembly, the long guideway assembly is moved up and down, drive glass along the gathering sill of the front and back end realization glass lifting function that moves up and down.

This structure, when glass reached the lower limit position, this moment was because reaction time of people etc. problem, operating personnel are release button at once not, thus make motor rotation blockage (be that motor continues power output, but since the motor shaft that is stuck do not rotate).Motor rotation blockage has very big injury to motor and tooth plate etc.

Summary of the invention

At the deficiencies in the prior art, the utility model provides automobile glass lifter, efficiently solves the problems referred to above.

The utility model is achieved through the following technical solutions: automobile glass lifter, comprise master arm, auxiliary, decide guide rail, moving guide rail, arc tooth plate, spline and base plate with the arc tooth plate engagement, described master arm is rotatably connected on the described base plate, and described master arm one end fixedly has arc tooth plate, described arc tooth plate and described spline engagement, the described master arm other end is slidingly arranged in the moving guide rail by slide block, described auxiliary and described master arm are rotationally connected and an end of described auxiliary is slidingly arranged in by slide block and decides in the guide rail, the other end of described auxiliary is slidingly arranged in the described moving guide rail by slide block, described arc tooth plate comprises the fixed part and the tooth-strip part that be slidingly arranged in described fixed part on fixing with master arm, at described tooth-strip part through hole is set, fixed part is provided with the chute that is communicated with described through hole, in described chute, spring is set, one push rod passes through hole and enters described chute and described spring leans, at described push rod dovetail groove is set, also comprise a block, the tooth-strip part sidewall is provided with draw-in groove, described block is arranged in described draw-in groove by fixed part, and described block and described push rod lean.

The utlity model has following beneficial effect: when glass reached the lower limit position, tooth bar broke away from tooth plate, and spline drives tooth bar and slides at tooth plate, therefore can not cause motor in the problem of lower limit position stall, had reduced the damage of motor and tooth plate.

The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail: referring to Fig. 1 to Fig. 4, automobile glass lifter, comprise master arm 1, auxiliary 2, decide guide rail 3, moving guide rail 4, arc tooth plate 10, spline 5 and base plate 7 with arc tooth plate 10 engagements, described master arm 1 is rotatably connected on the described base plate 7, and described master arm 1 one ends fixedly have arc tooth plate 10, described arc tooth plate 10 and described spline 5 engagements, the described master arm other end is slidingly arranged in the moving guide rail 4 by slide block, described auxiliary 2 is rotationally connected with described master arm 1 and an end of described auxiliary 2 is slidingly arranged in by slide block and decides in the guide rail 3, and the other end of described auxiliary 2 is slidingly arranged in the described moving guide rail 4 by slide block.

Described arc tooth plate 10 comprises the fixed part of fixing with master arm 1 20 and the tooth-strip part 21 that is slidingly arranged on the described fixed part, at described tooth-strip part 21 through hole 210 is set, fixed part 20 is provided with the chute 200 that is communicated with described through hole 210, in described chute 200, spring 201 is set, one push rod 100 passes through hole 210 and enters described chute 200 and leans with described spring 201, at described push rod 100 dovetail groove 102 is set, also comprise a block 101, tooth-strip part 21 sidewalls are provided with draw-in groove 103, described block 101 is arranged in described draw-in groove 103 by fixed part 20, and described block 101 leans with described push rod 100.

When spline 5 drive arc tooth plates up rotate (when also glass is descending), come downwards to the lower limit position, tooth top on the spline 5 makes push rod 100 interior contractings promote springs 201 by push rod 100 at this moment, and spring 201 compresses, block 101 enters dovetail groove 102, make block 101 break away from draw-in groove 103, if this moment, motor continued power output, then spline drives tooth-strip part 21 in fixed part 20 slips (being that master arm is not rotated further), therefore motor can stall, has reduced the damage of motor and tooth plate.
