Lifter
Technical field
The present invention relates to auto parts machinery field, more specifically, relate to a kind of for the lifter to lifting glass for vehicle window.
Background technology
Automobile glass lifter refers to by motor or manual actuation, and is risen or decline along glass gathering sill by automobile window glass by transmission mechanism, and can rest on the device of optional position on request.
Glass regulator is mainly divided into rope wheel type lifter in type, intersect arm-type lifter and teeth bar type up-down device, the structure of rope wheel type lifter can see as in number of patent application " 201210179668.8 " the structure announced, mainly comprise guide rail, the slide plate be sleeved on guide rail, the upper conductor wheel laying respectively at guide rail two ends and lower wire wheel, spool, be wound on wire rope on spool and motor, the two ends of described wire rope are walked around upper conductor wheel respectively and are taken turns with lower wire and be connected with slide plate.Drive winding logical by motor, thus Wound steel rope make wire rope drive the upper and lower slippage of slide plate be positioned on guide rail.Said structure, because slide plate is a movement parts, needs to proofread it in motion process when designing, and with the gap situation of each component in door body, if skateboard shape is slightly not in place, then just can interfere with component in door body when being elevated.In addition also there is the problem that easy deformation stretches in wire rope.
Intersecting the structure of arm-type lifter can see structure disclosed in such as number of patent application " 201320324325.6 ", mainly comprise master arm, slave arm, determine guide rail and dynamic guide rail, master arm one end is provided with arc tooth plate, also comprise the motor engaging described arc tooth plate, drive the arc tooth plate of master arm one end by motor thus make the quadric chain of master arm and slave arm composition drive vehicle window to rise.Above-mentioned riser structure, takies car door inner space comparatively large, therefore generally can only be applied on the oversize vehicle such as truck, lorry, and is movement parts due to master arm and slave arm, therefore when designing, is still difficult to control with the gap of door body inner components.
Rack-type window lifter structure comprises guide rail, on guide rail is longitudinal, is provided with tooth plate, slide on rails is provided with slide plate, slide plate is provided with the motor with tooth plate meshed gears and driven wheel.Make slide plate in the upper and lower slippage of guide rail by motor-driven gear.Because motor and slide plate itself are set to one, therefore movement parts slide plate is comparatively large on volume, during design, is still difficult to avoid the unmanageable problem in gap with door body inner components.
Summary of the invention
For the deficiencies in the prior art, the invention provides lifter.
The present invention is achieved through the following technical solutions: lifter, comprise vehicle window, also comprise conduit and be movably arranged on the flexible rack in described conduit, described conduit comprises the first pipeline, second pipe and the 3rd pipeline, described first pipeline is arranged with described second pipe is mutually vertical, described 3rd pipeline is circular arc and connects described first pipeline and described second pipe by described 3rd pipeline, described 3rd pipeline is provided with breach, be provided with and described flexible rack meshed gears in described indentation, there, described flexible rack lower end stretch out described chute and and described vehicle window affixed, rotate in described gear side and be provided with locking hook, described locking hook side is provided with the pushing block for promoting described locking hook, described pushing block slides and is arranged in a sleeve, the electromagnet attracting described pushing block is provided with bottom described pushing block, elastic component is provided with between described electromagnet and described pushing block.
The present invention has following beneficial effect: the present invention, by the guiding parts of conduit as tooth bar, namely drives the tooth bar of window lifting to slide in conduit completely, therefore can not produce with car door inner components and interfere; This outer catheter, as more convenient on guiding parts fabrication design, can arrange multi-form conduit according to car door internal construction flexibly.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail: see Fig. 1 to Fig. 3, a kind of window regulator, the flexible rack 2 comprising conduit 1 and be movably arranged in described conduit 1, described conduit 1 comprises the first pipeline 10, second pipe 11 and the 3rd pipeline 12, described first pipeline 10 and second pipe 11 vertical setting mutually, described 3rd pipeline 12 is circular arc and connects described first pipeline 10 and described second pipe 11 by described 3rd pipeline 12, above-mentioned first pipeline 10, second pipe 11 and the 3rd pipeline 12 one-body molded, described 3rd pipeline 12 arranges breach 12a, be provided with and described flexible rack 2 meshed gears 3 at described breach 12a place, described gear 3 is driven by motor (accompanying drawing is not shown), rotate in described gear 3 side and be provided with locking hook 5, described locking hook 5 side is provided with the pushing block 6 for promoting described locking hook 5, described pushing block 6 slides and is arranged in a sleeve 7, the electromagnet 8 attracting described pushing block 6 is provided with bottom described pushing block 6, elastic component 9 is provided with between described electromagnet 8 and described pushing block 6, described electromagnet 8 is connected with the supply module of motor.
When not using motor, also, window is positioned at window frame optional position when stopping, and locking hook 5, under the active force of pushing block 6 and elastic component 9, locks described gear 3, even if make it under vehicle window upper end is subject to larger pressure, also cannot rotate.
When opening described motor and driving flexible rack 2 to be elevated, pushing block 6 is attracted to electromagnet 8 position by described electromagnet energizing magnetic, now pushing block promotes the displacement to the right of described locking hook 5, locking hook 5 does not contact with gear 3, therefore ensure that when being normally elevated, locking hook 5 does not affect the transmission efficiency of gear and flexible rack.
Because the present invention adopts conduit as the guiding parts of tooth bar, namely drive the tooth bar of window lifting to slide in conduit completely, therefore can not produce with car door inner components and interfere; This outer catheter, as more convenient on guiding parts fabrication design, can arrange multi-form conduit according to car door internal construction flexibly.
