Abstract
The invention discloses a kind of teeth bar type up-down device, including slide rail fixed plate, lifter plate, the drive mechanism of setting on lifter plate, slide rail fixed plate includes pedestal and the rack-plate being slidably arranged on this pedestal, the spring being in compressive state it is provided with between pedestal and described rack-plate, pedestal is positioned at the left side of rack-plate and is provided with the block leaning described rack-plate, pedestal offers the groove accommodating block, block is arranged in described groove, and in groove, it is provided with the back-moving spring resetted so that block, stop bottom is provided with stay cord.Lifter of the present invention is when normally using, and owing to block leans rack-plate, therefore drive mechanism can not affect normal use with rack-plate good engagement；When emergency occurs, pull stay cord, block rack-plate is leaned effect release, now rack-plate displacement, drive mechanism cannot engage with rack-plate, now lifter plate can sliding in fixed plate easily, therefore can open vehicle window easily.
Description
Technical field
The present invention relates to automobile glass lifter field.
Background technology
The glass-frame riser used on existing automobile mainly uses cable pulley type and the arm-type lifter that intersects.Owing to above two lifter generally exists the problem that installing space is excessive, therefore the applicant devises a kind of teeth bar type up-down device in early days, number of patent application is " 201310106966.9 ", entitled " Rack-type window lifter ", including tooth bar slide rail and lifter plate, motor is set directly on lifter plate, drives lifter plate upper and lower displacement on tooth bar slide rail by motor, and this structure effectively reduces the installing space of lifter.
In addition the patent of number of patent application " 200420028538.5 " also discloses that similar riser structure.
But above two teeth bar type up-down device, when car something unexpected happened (falling into the situations such as korneforos such as car), the most easily produces electric motor short circuit thus cannot realize the unlatching of glass vehicle window, now can only be by means such as broken window hammers by glass crushing.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of teeth bar type up-down device, have teeth bar type up-down device installing space little while, it is possible to realize the unlatching of in case of emergency glass for vehicle window.
The present invention is achieved through the following technical solutions: a kind of teeth bar type up-down device, including slide rail fixed plate, it is slidably arranged in the lifter plate in described slide rail fixed plate, the drive mechanism arranged on described lifter plate, described slide rail fixed plate includes pedestal and the rack-plate being slidably arranged on this pedestal, the spring being in compressive state it is provided with between described pedestal and described rack-plate, described pedestal is positioned at the left side of described rack-plate and is provided with the block leaning described rack-plate, described pedestal offers the groove accommodating described block, described block is arranged in described groove, and in described groove, it is provided with the back-moving spring resetted so that described block, described stop bottom is provided with stay cord.
There is advantages that lifter of the present invention when normally using, owing to block leans rack-plate, therefore drive mechanism can not affect normal use with rack-plate good engagement；When emergency occurs, pull stay cord, block rack-plate is leaned effect release, now rack-plate displacement, drive mechanism cannot engage with rack-plate, now lifter plate can sliding in fixed plate easily, therefore can open vehicle window easily.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the present invention.
Fig. 2 be block schematic diagram is set..
Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings, see Fig. 1 to Fig. 2, a kind of teeth bar type up-down device, pedestal 10 and the rack-plate 11 being slidably arranged on this pedestal 10 is included including slide rail fixed plate 1, described slide rail fixed plate 1, described slide rail fixed plate 1 is slided and is provided with lifter plate 2, being provided with drive mechanism 3 on described lifter plate 2, described drive mechanism 3 includes and described rack-plate 11 upper rack meshed gears and the motor of the described gear of driving.Drive described gear driven gear and tooth bar to coordinate by motor thus drive lifter plate 2 to slide in described slide rail fixed plate 1.
The spring 12 being in compressive state it is provided with between described pedestal 10 and described rack-plate 11, described pedestal 10 is positioned at the left side of described rack-plate 11 and is provided with the block 13 leaning described rack-plate 11, described pedestal 10 offers the groove 10a accommodating described block 13, described block 13 is arranged in described groove 10a, and in described groove 10a, it is provided with the back-moving spring 13a resetted so that described block 13, it is provided with stay cord 13b bottom described block 13, when lifter is installed, stay cord 13b draws outside car door, therefore can pull described stay cord from car door.
nullWhen described lifter is properly functioning，Now block 13 is due under the effect of back-moving spring 13a，Rack-plate 11 is made to lean block 13，I.e. rack-plate 11 cannot continue direction slip (left direction in Fig. 1 is i.e. defined as left direction in embodiment) to the left，Now the gear in drive mechanism 3 and rack-plate 11 have good engagement，Thus without the normal use affecting lifter，When needing to open vehicle window when being in an emergency，Pull described stay cord 13b，Described block is made to be advanced into described groove 10a for 13 times,Now the effect that leans of described rack-plate 11 is released by block 13，And rack-plate 11 displacement to the left under the effect of spring 12，Now rack-plate 11 and driving mechanism gear engagement release，Therefore lifter plate 2 can in slide rail fixed plate 1 slidably，So the unlatching of in emergency circumstances vehicle window can be realized，And it is not required to destroy vehicle window.
