Description

Lifter guide rail assembly with high transmission efficiency

Technical Field

The utility model belongs to a component of an automobile glass lifter.

Background

At present, with the continuous expansion of the automobile market in China, customers not only meet the basic functions of automobiles, but also have higher and higher requirements on the quality of the whole automobiles. In order to meet the needs of customers, the automobile glass lifter industry is also continuously researching lifters and component structures thereof with high transmission efficiency and low noise quality in order to match the pace of the whole automobile factory. The high transmission efficiency can reduce the loss in the lifter mechanism, save the energy consumption of the whole vehicle and particularly greatly influence the electric vehicle; the noise problem has great influence on the public praise of the automobile brand.

The existing lifter guide rail assembly is structurally characterized in that guide parts are respectively assembled at two ends of a guide rail, a rotating wheel is positioned in the guide parts, and the rotating wheel, the guide parts and the guide rail are connected through rotating shaft screws so that the rotating wheel rotates at the guide parts. In the structure, the contact surface of the guide part and the rotating wheel is a plane, referring to fig. 5, the gap between the guide part and the rotating wheel is 0.15-0.25mm, and in the use process, the resistance of the rotating wheel in the rotating process inside the guide part is large, the rotating wheel is not flexible enough in rotating, the transmission efficiency is low, and simultaneously, noise and abnormal sound are easy to generate. After the steel wire rope 9 is wound on the rotating wheel, the steel wire rope is along the direction of the guide rail and is positioned above the guide rail, a process hole is formed in the guide rail, the process hole is punched, other processing is not performed on the hole after punching, burrs generally exist, the steel wire rope is in friction with the punched edge of the hole when moving, clamping stagnation is caused, the running resistance of the steel wire rope is increased, and the transmission efficiency is also reduced.

Disclosure of Invention

The utility model provides a high transmission efficiency's riser guide rail set spare to solve the transmission inefficiency that exists at present, there is the problem of noise and abnormal sound.

The utility model adopts the technical proposal that: the two ends of the guide rail are respectively provided with a first guide part and a second guide part, a first rotating wheel is positioned in the first guide part and is connected with the first guide part and the second rotating wheel through a first rotating shaft screw, the first rotating wheel is rotatably connected with the first guide part, the second rotating wheel is positioned in the second guide part and is connected with the second guide part and the second rotating wheel through a second rotating shaft screw, the second rotating wheel is rotatably connected with the second guide part, the plane of the first guide part is provided with an annular boss, the plane of the second guide part is provided with an annular boss, and the edge of a process hole in the guide rail is provided with a chamfer;

the height of the annular boss is 0.5 mm;

the height of the annular boss is 0.5 mm.

The utility model has the advantages that the structure is novel, the gap between the rotating wheel and the plane of the guide piece can reach 0.4-0.5mm, and the gap can reduce the resistance of the rotating wheel in the rotating process of the rotating wheel in the guide piece, so that the rotating wheel can rotate more flexibly and the noise is reduced; the edge of the stamping part of the guide rail process hole is provided with the chamfer, so that the steel wire rope can be prevented from being clamped and blocked due to friction with the burrs of the stamping hole when moving on the arc surface of the guide rail, the running resistance of the steel wire rope is reduced, the internal loss of the lifter mechanism is reduced, the transmission efficiency is higher, the energy of the whole lifter is saved, and the service life of a lifter motor is prolonged and the product quality is improved.
