Abstract

The utility model discloses an automobile electric vehicle window pane riser, which comprises a motor 1, a worm wheel worm reduction gear 2, a gear 3, a soft screw shaft 4, a vessel 5, a motor base 6, a microswitch 7, a protective pipe 8, a glass support bracket 9, a slide guide mass 11 and a support saddle 12. The window pane is provided on the glass support bracket which is fixed on the slide guide mass 11 on an end head of the soft screw shaft; the whole mechanism is arranged on a window door of the vehicle window by the support saddle 12. The utility model adopts the microswitch to guarantee the transient motor outloading and safety, meanwhile increases the inverse sensitivity, which adopts a multi-teeth mesh transmission to improve the stress condition of the drive mechanism thereby more steadily opening and losing the vehicle window with less noises, which is suitable for lifting the vehicle window panes of all the modern automobiles.

Description

The automobile electric car-window window regulator

One, technical field: mechanical equipment.

Two, background technology: known automobile window glass lifter extensively adopts forms such as tooth fan jointed gear unit and rope sheave transmission, tooth fan connecting rod mechanism uses the most general, its shortcoming is a complex structure, manually require great effort, electronic power consumption is big, adopt iron plate to be stamped to form because of the tooth fan is normal again, no quenching measure, quick abrasion, life-span is not long, and this external tooth fan connecting rod shape generally can only be done the oscilaltion campaign, can not realize the camber line dipping and heaving of glass vehicle window, can not adapt to the requirement of modern automobile moulding development, its utilization also is restricted.The cable pulley type transmission can be done straight line or curvilinear motion, its structure is also simpler, but because of it is to come transmission with the friction force between rope sheave, when rope is stretched deformation effect and is extended or tightening device lost efficacy, or rope sheave transmission slip and influence the reliability of work, the steel cable of the rope sheave lifter fracture that rubbed in addition influences its service life.

The patentee is called the automobile window glass elevator that discloses a kind of flexible screw transmission in " flexible screw transmission automobile window glass elevator " patent in name, it partly is made up of glass bracket, conduit, drive sleeve, balancing brake spring, transmission gear, flexible screw axle handle etc., is characterized in: adopt the balancing brake spring structure to guarantee that flexible screw shaft drive makes it stop at any position in the conduit.Flexible screw can be in conduit any position reciprocating or stop, but this glass lifter is because of being manual, effort operates, need the time of usefulness long, because be the monodentate transmission, period of service has been grown and has been difficult to make accurately glass for vehicle window to stop on the position, and window opening and closing is very not reliable and secure.

Three, summary of the invention

1. the objective of the invention is defective, on flexible screw manual transmission basis, become manual, adopt micro-switch to guarantee the safety of electronic instantaneous off-load and mechanism into electronic according to above-mentioned known technology.Improve reverse sensitieness simultaneously; Adopt multiple tooth engaged transmission, improve the force-bearing situation of transmission device, make work more steadily reliable.

2. technical scheme: Fig. 1,2, the 3rd, the design's composition constructional drawing.It is by motor 1, worm and gear speed-reduction apparatus 2, form with flexible screw gears in mesh 3, flexible screw axle 4, conduit 5, motor cabinet 6, micro-switch 7, pillar 8, glass bracket 9, balladeur train collision block 11, (see figure 3), bearing 12.Automobile window glass 10 places on the glass bracket 9; glass bracket is fixed on the balladeur train collision block 11 of flexible screw upper end, motor 1, worm and gear speed-reduction apparatus 2 are installed on the arrangements for automotive doors by motor cabinet 6; flexible screw is contained in the conduit 5; and pillar 8 protections are arranged outside the conduit 5, sleeve mechanism is installed on the vehicle window door by bearing 12.

During work, starter motor 1, gear 3 drive flexible screws 4 by motor-driven worm type of reduction gearing 2 output axle heads are done in conduit, following motion, drive the balladeur train collision block 11 of its termination and glass bracket 9 fixed thereon simultaneously and done dipping and heaving, also just realized the dipping and heaving of glass for vehicle window, the shape of conduit 5 is depended in glass for vehicle window moving linearly or movement in a curve, if conduit is rectilinear just moving linearly, conduit is a camber line shape, just do movement in a curve, when the glass vehicle window walks to, following not-go-end, by the collision block on the balladeur train collision block 11 that is connected as a single entity with glass bracket 9, when running into micro-switch 7, the just instantaneous disconnection of micro-switch, motor off-load is immediately quit work, and this mechanism makes the lifting of motor and flexible screw operation and glass vehicle window get at high speed and failure-free operation.

Compare with known technology, the design has adopted micro-switch, has guaranteed the safety of instantaneous off-load of motor and mechanism, has improved oppositely directed sensitieness simultaneously, has guaranteed safe, the reliable and sensitieness of lifting glass for vehicle window; Another advantage of the design is to have adopted multiple tooth engaged transmission when the flexible screw transmission, makes work more steady, has improved the force-bearing situation of transmission device, has reduced noise.

Four, description of drawings, Fig. 1 are the design's composition constructionals drawing, and 1 is motor among the figure, the 3rd, and gear, the 4th, flexible screw axle, the 5th, conduit, the 6th, motor cabinet, the 7th, micro-switch, the 8th, pillar, the 9th, glass bracket, the 12nd, bearing.Fig. 2 is that the n-n of Fig. 1 analyses and observe, and 2 is worm and gear speed-reduction apparatus among the figure, and Fig. 3 is that the m-m of Fig. 1 analyses and observe, and 10 is glasss for vehicle window, the 11st among the figure, the balladeur train collision block.

Five, the specific embodiment: power of motor 23-50 watt, worm type of reduction gearing is decelerated to 60-90 rev/min, with the flexible screw gears in mesh number of teeth be more than 2 teeth, flexible screw shaft diameter 6-7mm.
