Abstract

The invention relates to a coiling lifting type lifter with a spring buffer gear. The lifter comprises a driving mechanism, a lifter bracket and a lifter base. The lifter is characterized in that the lifter bracket is a rectangular stripe tube body, a gap is longitudinally arranged on the side wall of the tube body to form a slide rail, a rectangular strap guide slot is formed on the inner wall of the tube body of the lifter bracket, a strap is arranged in the strap guide slot, the upper end of the strap is coiled at the upper end of the lifter bracket and is arranged on a winding wheel on the lifer base, and the lower end of the strap is fixedly connected with a slide block which is locked in a slide rail; a winding wheel shaft is connected with the driving mechanism. The lifter provided by the invention has the beneficial effects that the window glass is coiled and pulled upward by virtue of a coiling wheel at the upper end of the strap, so that the tooth belt is prevented from being bended and deformed due to a promoting force of the toothed belt lifter; the lifter has the defects of great abrasion, easy stagnation, high failure rate and short service life; the driving gear is the buffer gear which has a protective effect on the gear, so that the service life of the lifter is prolonged.

Description

Winding pull-type spring buffer gear lifter

Art

The present invention relates to a kind of automotive window lifter, especially reel pull-type lifter.

Background technology

At present, its cingulum of teeth belt type lifter on market pushes and upwards pushes by the gear being arranged on cingulum bottom, and because cingulum is flexible, under the effect of the power of election, cingulum can occur bending and deformation, the frictional force of cingulum and cingulum guide groove sidewall is strengthened, the easy to wear and clamping stagnation of cingulum; In addition, the driven wheel of lifter is not with buffer, when running into obstacle or stop suddenly in window lifting process, driven wheel bears very large impact force, easily cause gear failure, above-mentioned reason all will cause window regulator fault rate to raise, and application life shortens.

Summary of the invention

In order to overcome the defect of existing automotive window lifter, the invention provides a kind of winding pull-type spring buffer gear lifter, suspender belt relies on the lift of the strip winding of end provided thereon wheel winding to pull and is provided with glass for vehicle window slide block, avoiding teeth belt type lifter due to election power makes cingulum flexural deformation, large, the easy clamping stagnation of wearing and tearing, the drawback that fault rate is high, the life-span is short.

The technical solution adopted for the present invention to solve the technical problems is: a kind of winding pull-type spring buffer gear lifter, comprise driving mechanism (25) and elevator shelves (11) and lifter base (38), it is characterized in that: elevator shelves (11) is rectangular slat shape body, tube wall longitudinally arranges one gap and forms slide rail (16), the inboard wall of tube body of elevator shelves (11) forms a rectangle suspender belt guide groove (47), a suspender belt (13) is provided with in suspender belt guide groove (47), the upper end of suspender belt (13) is wound in elevator shelves (11) the upper end strip winding be located on lifter base (38) and takes turns on (14), lower end and the slide block (19) be equipped in slide rail (16) of suspender belt (13) are fixedly connected, strip winding wheel shaft (24) connects with driving mechanism (25).

Described driving mechanism (25), it is configured to: one end of strip winding wheel shaft (24) connects with driving gear axle (31) keyway, driven wheel (30) is meshed with worm screw (29), is connected and is transmitted power between worm screw (29) with motor (12) by flexible axle (51).Glass for vehicle window is installed on slide block.

Described driven wheel (30), comprise toothed foreign steamer (1) and interiorly to take turns (2), foreign steamer (1) is enclosed within interiorly takes turns on (2), on foreign steamer (1), the spring groove (4) placing buffer spring (3) is provided with in interior foreign steamer joint, a pair buffer spring (3) is placed in spring groove (4), on interior wheel, be provided with in interior foreign steamer joint and insert caster (5) between spring groove (4) interior two buffer springs (3), the both sides of foreign steamer (1) be provided with fixing in the front stator (6) of foreign steamer and rear stator (7).The spring groove (4) of interior foreign steamer joint has one group at least.

The invention has the beneficial effects as follows that glass for vehicle window relies on the lift of the strip winding of suspender belt upper end wheel winding to pull glass for vehicle window up, avoid teeth belt type lifter and make cingulum flexural deformation due to election power, drawback that is large, easily clamping stagnation of wearing and tearing; Driven wheel is buffer gear cold, when can run into obstacle or stop suddenly in window lifting process, makes driven wheel have the process of a soft transitions to impact force, plays a protective role to gear, extend the application life of lifter.
