Description

Technical Field

[0001] The utility model relates to the technical field of window lifting, in particular to a lifting component of a window lifter. Background Art

[0002] With the continuous improvement of people's living standards, the popularity of vehicles is also getting higher and higher. During the use of vehicles, the windows often need to be opened and closed for ventilation and heat dissipation inside the vehicle. However, after the windows are opened, various problems also occur. For example, when driving or parking, dust enters the door panel, damaging the electrical equipment inside the door panel, resulting in the failure of electrical components and the inability to use the window normally. It is urgent to improve the traditional glass lifter for new energy vehicles;

[0003] The window lifter lifting component with the publication number of CN 112377031 A includes a fixed plate and two sliding plates fixed on the fixed plate. A limiting block is arranged on the sliding plate. A sliding rod is connected between the sliding plates through a first sliding sleeve. A track is arranged on the sliding plate. A cross bar is also arranged between the sliding plates. An installation strip is arranged on the cross bar and a track is also arranged. The sliding rod and the cross bar are connected through a connecting strip. The connecting strips are hinged to each other. A contact block is arranged at the connection between the connecting strip and the track on the cross bar. The contact block abuts against a second sliding sleeve arranged on the cross bar. The second sliding sleeve is connected to an adjusting component;

[0004] When it is in use, the friction between its slider and the chute is large, so that during the multiple lifting and lowering processes of the window glass, the slider is prone to wear, reducing the degree of fit between the slider and the chute, making the window prone to shaking. Moreover, it is difficult to disassemble the slider of this device, making it time-consuming and laborious for the staff to disassemble or install; Therefore, we propose a lifting component of a window lifter.
