Cam type glass ascending and descending device

Abstract

The invention discloses a cam type glass ascending and descending device. The cam type glass ascending and descending device comprises a power gear and a glass clamp. One side of the power gear is connected with a piston rod of a cylinder through a crankshaft connecting rod structure. A cam device is fixed above the power gear and rotates with the power gear. The cam device is a cylindrical rod body. A curve groove is formed above the cylindrical rod body, or a component of a curved groove is formed above the cylindrical rod body. The glass clamp is fixed to a roller embedded in the curved groove. The roller is arranged in the curved groove in a rolling mode. The curved groove is symmetrically arranged according to the center line of the cylindrical rod body. The vertical height of the curved groove is distributed on the cylindrical rod body according to a clockwise random variable function. According to the cam type glass ascending and descending device, power of the glass ascending and descending device is provided by using a cylindrical cam; and because the curved groove is matched with the inclination angle of glass, in the ascending and descending process, the relative position between the center of gravity of the glass clamp and the center of mass of the glass is unchanged all the time, the movement stability is improved, and the generation of inclination or clamping during ascending and descending of the glass is avoided.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a cam type glass lifter. Background technique [0002] Auto parts are the units that constitute the overall processing of auto parts and the products that serve the processing of auto parts. The glass regulator is the lifting device for the door and window glass of the car. It is mainly divided into two categories: electric glass regulator and manual glass regulator. [0003] Existing automotive glass lifters can be installed and used with car doors. The structure of the single-arm glass lifter is characterized by only one lifting arm. The structure is the simplest, but because the relative position between the support point of the lifting arm and the glass center of mass often changes When the glass is raised and lowered, it will be tilted and stuck; the structural feature of the double-armed glass lifter is that it has two lifting arms. The force is also relatively large, b...

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
