Description

Vehicle window driving device and vehicle

Technical Field

The utility model relates to the field of vehicle parts, in particular to a novel vehicle window driving device and a vehicle with the same.

Background

Fig. 1 shows a conventional window drive. The window driving device includes a driving motor 11, and an output shaft 12 of the driving motor 11 constitutes a worm, which is engaged with teeth of an outer race of a worm wheel 13, and the worm wheel 13 further drives a window 14 to move up and down through a transmission mechanism. When the window is moved to the upper limit position, namely when the window is closed, the window has certain kinetic energy, and when the window is stopped at the upper limit position, the kinetic energy can be absorbed by the worm gear mechanism, so that the worm gear mechanism is deformed and clamped. In addition, additional friction will be provided as the window is closed for a longer period of time or the seals on the window age. Whether the worm gear is clamped or otherwise caused by friction, constitutes an additional resistance to opening the window, which may result in insufficient motor drive to drive the window down.
