Abstract
The utility model discloses a rack type lifter. The rack type lifter comprises a slide rail fixing board, a lifting board and a drive mechanism arranged on the lifting board, the slide rail fixing board comprises a base and a rack board arranged on the base in a sliding mode, a spring in the compression state is arranged between the base and the rack board, the position, on the left side of the rack board, of the base is provided with a stop dog abutting against the rack board, the base is provided with a groove for containing the stop dog, the stop dog is arranged inside the groove, a reset spring enabling the stop dog to reset is arranged in the groove, and a stay cord is arranged at the bottom of the stop dog. When the lifter is normally used, as the stop dog abuts against the rack board, the drive mechanism can be well meshed with the rack board, and normal use is not affected; when an emergency happens, the stay cord is pulled, the rack board is released from the stop dog, at the moment, the rack board shifts, the drive mechanism can not be meshed with the rack board, the lifting board can slide on the fixing board easily, and therefore an automobile window can be opened easily.
Description
Technical field
The utility model relates to automobile glass lifter field.
Background technology
The glass-frame riser using on existing automobile mainly adopts cable pulley type and intersects arm-type lifter.Due to above-mentioned two kinds of excessive problems of lifter ubiquity installing space, therefore the applicant has designed a kind of teeth bar type up-down device in early days, number of patent application is " 201310106966.9 ", name is called " rack-and-pinion glass-frame riser ", comprise tooth bar slide rail and lifter plate, motor is set directly on lifter plate, by motor, drives lifter plate upper and lower displacement on tooth bar slide rail, and this structure has effectively reduced the installing space of lifter.
In addition in the patent of number of patent application " 200420028538.5 ", similar riser structure is also disclosed.
But above-mentioned two kinds of teeth bar type up-down devices, when car something unexpected happened (falling into the situations such as korneforos as car), thereby all easily produce the unlatching that motor short circuit cannot realize 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 utility model provides a kind of teeth bar type up-down device, have teeth bar type up-down device installing space little in, can realize the in case of emergency unlatching of glass for vehicle window.
The utility model is achieved by the following technical solution: a kind of teeth bar type up-down device, comprise slide rail fixed head, be slidably arranged in the lifter plate on described slide rail fixed head, the driving mechanism arranging on described lifter plate, described slide rail fixed head comprises pedestal and is slidably arranged in the rack-plate on this pedestal, between described pedestal and described rack-plate, be provided with the spring in compressive state, the left side that described pedestal is positioned at described rack-plate is provided with the block that leans described rack-plate, on described pedestal, offer the groove that holds described block, described block is arranged in described groove, and in described groove, be provided with the back-moving spring that described block is resetted, in described stop bottom, be provided with stay cord.
The utlity model has following beneficial effect: the utility model lifter when normal use, because block leans rack-plate, thus driving mechanism can with rack-plate good engagement, do not affect normal use; When there is emergency, pull stay cord, block is removed the effect that leans of rack-plate, now rack-plate displacement, driving mechanism cannot mesh with rack-plate, and now lifter plate can slippage on fixed head easily, therefore can open easily vehicle window.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present utility model.
Fig. 2 is the schematic diagram that arranges of block.。
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. 2, a kind of teeth bar type up-down device, comprise that slide rail fixed head 1, described slide rail fixed head 1 comprise pedestal 10 and be slidably arranged in the rack-plate 11 on this pedestal 10, on described slide rail fixed head 1, slide and be provided with lifter plate 2, on described lifter plate 2, be provided with driving mechanism 3, described driving mechanism 3 comprises the motor with described rack-plate 11 upper rack meshed gears and the described gear of driving.Thereby by motor, driving described gear driven gear and tooth bar to coordinate drives lifter plate 2 to slide on described slide rail fixed head 1.
At described pedestal 10 and 11 of described rack-plates, be provided with the spring 12 in compressive state, the left side that described pedestal 10 is positioned at described rack-plate 11 is provided with the block 13 that leans described rack-plate 11, on described pedestal 10, offer the groove 10a that holds described block 13, described block 13 is arranged in described groove 10a, and in described groove 10a, be provided with the back-moving spring 13a that described block 13 is resetted, in described block 13 bottoms, be provided with stay cord 13b, when lifter is installed, stay cord 13b draws outside car door, therefore can from car door, pull described stay cord.
When described lifter normally moves, under the now effect of block 13 due to back-moving spring 13a, make rack-plate 11 lean block 13, be that rack-plate 11 cannot continue direction slip (the left direction in Fig. 1 is defined as left direction in embodiment) to the left, now the gear in driving mechanism 3 and rack-plate 11 have good engagement, therefore can not affect the normal use of lifter, in the time of need to opening vehicle window when being in an emergency, pull described stay cord 13b, make described block be advanced into described groove 10a for 13 times, the now effect that leans of 13 pairs of described rack-plates 11 of block is removed, and rack-plate 11 displacement to the left under the effect of spring 12, now rack-plate 11 and driving mechanism gear engagement are removed, therefore lifter plate 2 can be free to slide on slide rail fixed head 1, so can realize the in emergency circumstances unlatching of vehicle window, and do not need to destroy vehicle window.
