Abstract
Disclosed is a multi-functional support arm-type window lifter. The multi-functional support arm-type window lifter comprises a seat plate, a toothed plate, a long chute, a short chute, a small arm and a large arm. The small arm is hinged with the middle of the large arm. Two ends of the small arm are respectively arranged in the long chute and the short chute through sliding blocks. The large arm is fixedly riveted with the toothed plate to form a large-arm toothed-plate combination. The toothed plate is mounted on the seat plate through a seat plate pin. A 0.2mm-0.5mm reserved clearance is formed between the seat plate and the toothed plate. By the lifter, the seat plate is movably riveted with the large-arm toothed-plate combination without fixed riveting, and accordingly starting torque of an electric motor and system resistance of the lifter are effectively reduced, lifting force of the lifter is improved, and service life of the whole window lifter is prolonged.
Description
Technical field
The utility model relates to a kind of support arm type glass-frame riser for car door window glass lifting, belongs to car door window glass lifting technical field.
Background technology
Glass-frame riser came across for the 60 to 70's abroad, and development is in recent years quite rapid.At the eighties initial stage, electric glass lifter is also the piece installing of selecting as limousine, but has nowadays started to be more and more applied on heavy-duty car.
The extensive use on heavy-duty car of support arm type glass-frame riser, there is feature easy to process, cost is low, on current domestic vehicle, use comparatively general, its shortcoming is that it adopts cantilevered support structure and gear tooth plate mechanism to working resistance greatly, its transmission mechanism is gear tooth plate, engaged transmission, except gear, its main member is plank frame, tooth plate is to be generally arranged on seat board by seat board bearing pin, tooth plate and the gear engagement that moment of torsion is provided, gear is arranged on motor or on lifting handle.This lifter is connected to the structure of " extremely riveted joint " by seat board and tooth plate with seat board bearing pin, the staring torque (or handle moment of torsion) of motor is increased, and SR is large, has reduced application life.
In heavy-duty car door and window electric glass lifter, because the general vehicle glass lifting resistance of glass of door and window lifting resistance ratios is large, and lifter working environment and working under hard conditions, in use cause elevator motor to damage too early and inefficacy cisco unity malfunction, therefore existing heavy-duty car door and window electric glass lifter is shorter application life.
Owing to being subject to the restriction of the aspects such as heavy vehicle space, glass quality, requirement to heavy vehicle electric lifter is also more and more higher, how to reduce the resistance of lifter self system, improve the application life of lifter, become the important topic of restriction lifter development.
Summary of the invention
The deficiencies such as the utility model is large for the lifting resistance of existing support arm type car door window glass lifting device existence, application life is short, provide a kind of lifter running resistance that can reduce, and improve the lifter multi-functional support arm type glass-frame riser in application life.
Multi-functional support arm type glass-frame riser of the present utility model, by the following technical solutions:
This lifter, comprise seat board, tooth plate, long chute, short groove, forearm and large arm; forearm is hinged with the middle part of large arm; the two ends of forearm by slide block, be arranged in long chute respectively and short groove in; large arm is fixedly riveted on tooth plate, forms large arm tooth plate assembly, and tooth plate is arranged on seat board by seat board bearing pin; between seat board and tooth plate, have preset clearance, and this preset clearance is 0.2mm-0.5mm.
Above-mentioned lifter designs certain preset clearance when seat board and the large arm combined riveting of tooth plate, has reduced the frictional force producing while moving each other, reduces the running resistance of system, improves the application life of lifter.
The utility model becomes " moveable riveting connects " by " extremely riveted joint " between seat board and large arm tooth plate assembly, not only effectively reduced the staring torque (or handle moment of torsion) of motor, and reduced the SR of lifter, improve the lifting force of lifter, extended the application life of whole glass-frame riser.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing support arm type glass-frame riser.
Fig. 2 is the annexation schematic diagram of seat board in the multi-functional support arm type glass-frame riser of the utility model, tooth plate and large arm.
Wherein: wherein: 1, seat board, 2, long chute, 3, short groove, 4, forearm, 5, large arm, 6, tooth plate, 7, seat board bearing pin, A, preset clearance.
The specific embodiment
Multi-functional support arm type glass-frame riser of the present utility model, as shown in Figure 1, comprise long chute 2, short groove 3, forearm 4, large arm 5 and tooth plate 6; forearm 4 is hinged with the middle part of large arm 5; two ends of forearm 4 are arranged in long chute 2 and in short groove 3 by slide block respectively; large arm 5 is fixedly riveted on tooth plate 6, forms large arm tooth plate assembly.Tooth plate 6 is riveted on seat board 1, referring to Fig. 2 by seat board bearing pin 7.When riveted joint, make seat board 1 and tooth plate 6 have each other certain preset clearance A, this preset clearance A is 0.2mm-0.5mm, frictional force each other while reducing lifter operation with this, and then the SR of reduction lifter, lifting force and the application life of improving lifter.Tooth plate 6 and the gear engagement that moment of torsion is provided, gear is arranged on motor or on lifting handle.
The course of work of above-mentioned multi-functional support arm type glass-frame riser is:
Short groove 3 is fixed on automobile, when lifter moves, by driven by motor tooth plate 6, rotate, by the engagement of gear and tooth plate 6, the large arm 5 of torque drive passing over is along the center rotating of seat board bearing pin 7, and drives forearm 4 to rotate, each slide block is in long chute 2 or the interior operation of short groove 3, drive long chute 2 to move up and down, and drive glass bracket to drag glass along guide rail, to move up and down, realize glass by the rise and fall of desired trajectory.
Riveting method between the large arm assembly of seat board 1 and tooth plate, has become " moveable riveting connects " from " extremely riveted joint ", has not only effectively reduced the staring torque of lifter, and has improved the lifting force of lifter, has extended the application life of whole glass-frame riser.
