The invention discloses a device for preventing the stroke excess of a vehicle window curtain. The device comprises a vehicle window frame, a curtain body, an upper rotating roller and a lower rotating roller. The upper rotating roller and the lower rotating roller are arranged on the upper side and the lower side in a frame body of the vehicle window frame respectively. The curtain body wraps theupper rotating roller and the lower rotating roller. By arranging the upper rotating roller and the lower rotating roller on the upper side and the lower side in the frame body of the vehicle windowframe, the curtain body is independently controlled to be opened and closed, the stroke excess of the vehicle window curtain is prevented, the curtain body is well protected, the service life of the device is prolonged, and the corresponding use cost is reduced. When an extension spring is in an initial state in the figure and a second motor controls the upper rotating roller through a second transmission shaft to put down the curtain body, the lower rotating roller automatically extends downwards under the effect of the tensile force and resilience of the extension spring, the curtain body isin a tightened state all the time, and it is avoided that the curtain body is blown by wind and the shielding effect of the curtain body cannot be realized.
Description
technical field [0001] The invention relates to the technical field of devices for preventing overtravel of vehicle windows and curtains, in particular to a device for preventing overtravel of vehicle windows and curtains. Background technique [0002] Car curtains refer to devices installed in the compartment to achieve shading, heat insulation, and privacy protection. In actual use, the following disadvantages still exist: [0003] Existing car window curtains are easy to overtravel in the process of lifting, which is easy to cause hard wear on the curtains, reduces the service life of the curtains, and increases the corresponding use cost. Contents of the invention [0004] The object of the present invention is to provide a device for preventing overtravel of window curtains, so as to solve the problems raised in the above-mentioned background technology. [0005] In order to achieve the above object, the present invention provides the following technical solutions: ...
