Abstract
The utility model discloses a cooperation mechanism of slider and slide rail, set up the slider in the slide rail including the slide rail with sliding, be provided with the trapped fuel groove on the slider, be provided with the through -hole on the trapped fuel groove, be provided with the sealing member on the through -hole, the sealing member includes the sleeve, be provided with the breach at this sleeve tip, set up the steel ball of sealing sleeve breach in the sleeve, the steel ball is pushed up by a spring and leans on, still including the gasbag that is used for going into compressed air source to trapped fuel inslot drum, gasbag and the one -way intercommunication in trapped fuel groove, set up first magnet on the gasbag, set up the second magnet the same with first magnet magnetic pole on the slide rail. The utility model discloses a thereby the compression gasbag makes the oil in the trapped fuel groove extruded, because when the door window slided, the decrement ( volume change volume) of gasbag became more and more invariable, has consequently guaranteed oil leak at every turn and has measured controllablely at every turn to going up and down when the door window when lieing in relative position and stop to two magnets, because the gasbag volume did not change this moment, consequently can not result in the oil in the trapped fuel groove to leak always yet.
Description
Technical field
The utility model relates to automotive window lifter field, more specifically, relates to the matching mechanism of lifter slide block and slide rail on a kind of lifter.
Background technology
The applicant and submitted the utility model patent that application number is " 201320122351.0 " on 03 18th, 2013, it is disclosed that the matching mechanism of slide block and slide rail, be included in described slide block near the trapped fuel groove that its sidewall locations is arranged, described trapped fuel groove has the through hole be communicated with slider side wall, one plug is stifled to be located in described through hole, plug side and a spring top, by (thus making it have the trend of seal plug), guiding cheekn are provided with the projection coordinated with described plug.When each slide block slides onto described raised position, described plug lean by described projection, thus plug is deviate from from through hole, now can spill the oil of a part for lubrication from trapped fuel groove.
But find in actual tests process, easily there are wearing and tearing in said structure plug part after slide block repeatedly slippage, now easily cause and lost efficacy with male cooperation, namely cause the plug when sliding onto raised position not lean projection or lean protruding live part reducing, thus cause few leakage of oil not even leakage of oil in trapped fuel groove.This external when window lifting to protruding to lean with plug position stops time, will cause leakage of oil always in through hole, thus cause the excessive of lubrication oil, cause waste.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the matching mechanism of slide block and slide rail.
The utility model is achieved by the following technical solution: the matching mechanism of slide block and slide rail, comprise slide rail and be slidably arranged in the slide block in described slide rail, described slide block is provided with trapped fuel groove, described trapped fuel groove is provided with the through hole be in communication with the outside, described through hole is provided with seal, described seal comprises sleeve, this sleeve ends is provided with axially extended breach, the steel ball of seal sleeve breach is set in described sleeve, described steel ball is leaned on by a spring top, also comprise one for the air bag blasting compressed gas source in trapped fuel groove, described air bag and described trapped fuel groove unilaterally connected, described air bag arranges the first magnet, described slide rail arranges second magnet identical with described first magnet poles.
The utility model has following beneficial effect: the utility model is by compressing gasbag thus the oil in trapped fuel groove is extruded, during due to each vehicle window slippage, the decrement (volume change) of air bag is tending towards constant, therefore ensure that each leakage of oil amount is controlled, and when being positioned at relative position stopping when window lifting to two magnet, because now air bag volume does not change, the oil in trapped fuel groove therefore also can not be caused to leak always.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail: see Fig. 1 to Fig. 3, the matching mechanism of slide block and slide rail, the slide block 1 comprising slide rail 2 and be slidably arranged in described slide rail 2, described slide block 1 is provided with trapped fuel groove 10, described trapped fuel groove 10 is provided with the through hole 10a be in communication with the outside, described through hole 10a is provided with seal 3, described seal 3 comprises sleeve 30, this sleeve 30 end is provided with axially extended breach 31, the steel ball 32 of seal sleeve breach 31 is set in described sleeve 30, described steel ball 32 is leaned by a spring 33, also comprise one for the air bag 11 blasting compressed gas source in trapped fuel groove 10, described air bag 11 (can make air bag be communicated with trapped fuel groove 10 by one way valve etc. with described trapped fuel groove 10 unilaterally connected, to prevent oil in trapped fuel groove 10 by suck-back in air bag), described air bag 11 arranges the first magnet 11a, described slide rail 2 arranges second magnet 20 identical with described first magnet 11a magnetic pole.
The utility model principle is as follows: at slide block 1 on slide rail 2 during slippage (the first magnet is away from the second magnet positions), now the steel ball 32 of seal is under the effect of spring 33, described through hole 11a is sealed, now oil cannot spill from through hole 10a, when slide block 1 slides onto the first magnet near the second magnet positions, because two magnet poles are identical, therefore described first magnet is ostracised and is caused described air bag 11 to be compressed, thus it is inner compressed air to be blasted described trapped fuel groove 10, now trapped fuel groove 10 inside produces larger pressure instantaneously, make steel ball 32 slow astern end movement, the oily breach 31 along sleeve 30 is extruded to the lubrication for slide rail on slide rail 2.
When window lifting to the first magnet and the second magnet are positioned at relative position stopping, because this state lower gasbag volume does not change (namely can not blast compressed gas source in trapped fuel groove), the oil in trapped fuel groove therefore also can not be caused to leak always.
