Abstract
The utility model discloses an automobile glass lifter, in particular to a crossed arm type window lifter which comprises a driving arm, an auxiliary arm, a fixed guide rail, a moving guide rail, an arc-shaped toothed plate, a gear meshed with the arc-shaped toothed plate and a baseplate, wherein the arc-shaped toothed plate has a toothed part and a smooth part; when the piece of glass reaches an upper limit position, the gear enters into the smooth part; and a spring is arranged at the rotational connection part of the driving arm and the baseplate. According to the utility model, when the piece of glass reaches an upper limit position, and the gear enters into the smooth part of the arc-shaped toothed plate, so that the situation that a motor still drives the gear to be meshed with the toothed plate, and damages are caused for the motor, the gear and toothed plate is avoided.
Description
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 arm-type riser structure such as Fig. 1 of intersecting, mainly be to be driven by direct current generator, by motor internal gear, outside driving toothed plate 2 and by master arm 3, decide the motion of the four-bar mechanism that guide rail 5, auxiliary 6 form, glass for vehicle window risen 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 1 of glass-frame riser is fixed on the support, and support is fixed on the interior panel beating, decides guide rail 5 and is horizontally fixed on the panel beating, and glass is fixed on the moving rail assembly 7 of lifter by two screws.By the rotation of motor, drive and rotate tooth plate 2 rotations, make auxiliary 6 do forward, the reverse rotation certain angle around pivot pin 4; Simultaneously master arm 3 is run-on point with the axis, pulley assembly 8 decide guide rail 5 and long lead to kneel in the assembly 7 make back and forth movement, 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.
The lifter of this structure when glass is up to the extreme higher position (this moment operating personnel not at once release button) makes motor still continue driven wheel and meshes with tooth plate, and motor and gear tooth plate have all been caused infringement.Therefore be necessary to improve.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of intersection arm-type glass-frame riser, efficiently solves the problems referred to above.
The utility model is achieved through the following technical solutions: intersect arm-type glass-frame riser, comprise master arm, auxiliary, decide guide rail, moving guide rail, arc tooth plate, with arc tooth plate meshed gears and base plate, 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 the engagement of described gear, 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 guide rail, the other end of described auxiliary is slidingly arranged in described moving guide rail by slide block, described arc tooth plate is divided into tooth portion and smooth department, when glass reaches the upper limit position, described gear enters described smooth department, at the place of being rotationally connected of described master arm and base plate torsion spring is set.
The utlity model has following beneficial effect: on glass when being raised to the upper limit position, gear enters into the smooth department of arc tooth plate, has avoided motor still to continue driven wheel and tooth plate engagement, and motor and gear tooth plate have all been caused infringement.
Description of drawings
Fig. 1 is the structural representation of the arm-type lifter of conventional cross.
Fig. 2 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail: referring to Fig. 2, intersect arm-type glass-frame riser, comprise master arm 1, auxiliary 2, decide guide rail 3, moving guide rail 4, arc tooth plate 10, with arc tooth plate 10 meshed gears 5 and base plate 7, described gear 5 is by motor-driven, 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 gear 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 guide rail 3, the other end of described auxiliary 2 is slidingly arranged in described moving guide rail 4 by slide block, described arc tooth plate 10 is divided into tooth portion 100 and smooth department 101, when glass reaches the upper limit position, described gear 5 enters described smooth department 101, at the place of being rotationally connected of described master arm 1 and base plate 7 torsion spring 6 is set.
Said structure, at glass lifting when the upper limit position, torsion spring 6 distortions, gear 5 enters arc tooth plate 10 smooth departments, in smooth department idle running (time of idle running is the reaction time of operating personnel's release button), namely do not continue with arc tooth plate on the tooth engagement.So just reduced the infringement for motor and arc tooth plate.When operating personnel's release button, when namely motor stopped driven wheel 5, torsion spring 6 drove arc tooth plates 10, made arc tooth plate 10 meshing gear 5 again.
