A cam type glass lifter

Abstract

The invention discloses a cam-type glass lifter, which includes a power gear and a glass clamp, one side of the power gear is connected to the piston rod of the cylinder through a crankshaft connecting rod structure; a cam device is fixed above the power gear, and the cam device rotates with the power gear ; The cam device is a cylindrical rod with a curved groove above the cylindrical rod or a component that makes a curved groove above the cylindrical rod; the glass clip is fixed on the roller embedded in the curved groove through the connecting rod, The rollers roll and are arranged in the curved groove; the curved groove is arranged symmetrically according to the center line of the cylindrical rod body, and the vertical height of the curved groove is distributed on the cylindrical rod body clockwise as a random variable function. The invention uses cylindrical cams to provide the power of the glass lifter, and utilizes the curve grooves and glass inclination angles to cooperate. During the lifting process, the relative position between the center of gravity of the glass clamp and the glass center of mass remains unchanged, improving the stability of the movement and avoiding the lifting of the glass Occurs when tilted or stuck.

Description

Technical field[0001]The present invention relates to the field of automotive parts, and more particularly to a cam type glass lift.Background technique[0002]Automotive parts are all units that make up the overall auto parts and the products serving automotive parts, while the glass lift is the lifting device of the automobile door and window glass, mainly divided into two major categories of the electric glass lift and manual glass lifter.[0003]Existing car glass lift, can be used in combination with the door installation, the structure of the single-arm glass lift is only one lifting arm, the structure is the simplest, but the relative position between the lifting arm support point and the glass centroid changes frequently. When the glass lifts, tilt, stuck; the structure characteristics of the red arm glass lift is the two lifting arms, compared to the single-arm glass lift, the red arm glass lift itself ensures parallel to the glass, improvement The force is also relatively larg...

AI Technical Summary

Problems solved by technology

[0003] Existing automotive glass lifters can be installed and used with car doors. The structural feature of the single-arm glass lifter is that there is only one lifting arm, which is the simplest in structure. When the glass is raised and lowered, there will be tilting and stagnation; the structural feature of the double-armed glass lifter is that it has two lifting arms. The force is also relatively large, but due to the small support width and large changes in the working load, the smoothness of motion is not as good as the former

[0004] Most of the aerodynamically designed automobile glass is tilted at a certain angle, and the relative position between the center of gravity of the glass clip and the center of mass of the glass will always change in the existing glass lifter, and the glass will be tilted or tilted when the glass is lifted or lowered. stuck problem
