Description

Technical Field

[0001] This utility model relates to the field of motorhome window lifting technology, specifically a silent lifting mechanism for motorhome electric windows. Background Technology

[0002] Car windows are important components in automobiles used to provide visibility, protect occupants, and maintain the interior environment. They allow for good lighting inside the vehicle, enable passengers to observe the external environment and monitor the vehicle's movement, and allow for air circulation between the inside and outside of the vehicle when the windows are lowered.

[0003] However, existing window lift mechanisms often encounter dust and debris falling into the inner layer of the window through gaps during use, and some lubricating oil also drips onto the inner layer and clumps together, making noise and affecting people's use.

[0004] To address the aforementioned deficiencies, Chinese Patent Publication No. CN216446742U discloses a vehicle window lifting mechanism, comprising a window frame, a lifting mechanism, a cleaning mechanism, and a fixing mechanism. The window frame has an internal cavity, with the lifting mechanism installed at the bottom of the cavity and the cleaning mechanism installed within it. The fixing mechanism is mounted on the upper part of the inner wall of the window frame. The lifting mechanism includes a tube frame installed within the window frame cavity, a spiral tube welded to one end of the tube frame, a drive source installed at one end of the spiral tube, a push rod installed at the other end of the spiral tube, a roller adapted to the inner side of the tube frame, a long rod connected to the outside of the roller, a connector installed at the middle of the long rod, a fixing component fixed to the inner side of the tube frame, and springs installed at both ends of the fixing component. A cleaning device is included, which, when the lifting mechanism is raised or lowered, drives the cleaning device at the bottom. The cleaning device uses a sliding scraper at the bottom to remove accumulated debris.

[0005] The aforementioned device uses a cleaning device to clean up internal debris during use, thereby reducing noise. However, the window structure in the aforementioned device is relatively complex, and the unevenness during raising and lowering can easily cause abnormal noises when the window moves upward, thus affecting the user experience.

[0012] Furthermore, a positioning rod is movably mounted on the inner side of the slider, and a housing is fixedly mounted on the outer surface of the positioning rod.

[0013] Furthermore, a slider is movably abutted against the inner side of the outer shell, and a fixing block is provided on the outer surface of the slider.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The drive shaft is driven to rotate by the drive assembly, the drive shaft drives the transmission roller to rotate, the transmission roller drives the steel wire rope to wind up, and the set pulley transmits the steel wire rope to increase the stability during lifting and lowering, avoid abnormal noise during lifting and lowering that affects the experience of the personnel, and the steel wire rope drives the slider carrying the glass to move, thereby realizing the efficient lifting and lowering of the glass.

[0017] (3) The toothed grooves on the ruler are meshed with the drive gear, which drives the transmission roller to rotate. The transmission roller drives the wire rope to wind up. There are two sets of transmission rollers, which are driven by two sets of electric push pumps to increase the stability of lifting.

[0018] (4) The steel wire rope is wound up by the transmission roller and the pulley is used to assist in the transmission, thereby reducing the noise generated, thereby driving the slider to move along the positioning rod. The glass is set on the side of the fixed block away from the slider, which makes it easier for the glass to achieve the effect of lifting and lowering. Attached Figure Description
