Problems solved by technology
[0007] Also, because the rolling of the electric shade is done by electricity, it must be equipped with an automatic stretching frame that stretches the curtain backwards, and the stretching frame must have a relative stretching force, otherwise the curtain will collapse without tension.
But there is a problem here. Neither the power nor the reducer has absolute self-locking ability, so after the curtain is retracted, it is possible that the shade curtain wound on the roller shade tube will be slowed down by the stretching force of the automatic stretching frame. slow pull condition

The invention discloses an electric transmission device for a vehicle curtain, which comprises a curtain frame, an automatic extension frame, a roller shutter tube, and an electric transmission mechanism. The left and right ends of the curtain frame are respectively provided with curtain frame covers. The fixed connector in the cover of the curtain frame on one side is sleeved with an electric transmission mechanism; the cover of the curtain frame on the other side is connected to the movable shaft of one end of the roller shutter tube, and the driving force receiving part is fixedly arranged in the roller shutter tube; The transmission mechanism includes a transmission housing, a motor and a reducer installed in the transmission housing. The inner end of the transmission housing is fixed with a winding tube brake mechanism, one side is connected with the reducer, and the other side of the coil tube brake mechanism is the first The transmission connector is fixedly sleeved in the first driving force receiving hole, the outer diameter of the transmission housing is smaller than the inner diameter of the roller blind tube, and the roller blind tube can rotate freely outside the electric transmission mechanism. The utility model has the advantages of scientific and reasonable structure, better safety of the electric transmission mechanism, and stronger self-locking ability of the coiled tube brake mechanism. Make car blinds more fully automated.
Description
technical field [0001] The invention relates to a vehicle curtain, in particular to a fully automatic electric transmission device for a vehicle curtain with a self-locking function. Background technique [0002] With the development of the automobile manufacturing industry, the technical requirements for the field of auto parts are also rapidly increasing. Many vehicles, such as SUVs, are equipped with curtains in the trunk. Therefore, there are a wide variety of shades and various related technical solutions in this field. [0003] The covering curtain can block various objects in the trunk, and can place lighter items on the covering curtain, so that the vehicle is more tidy and beautiful, and is very practical. Most of the existing automobile blinds are semi-automatic, that is, an automatic roller blind mechanism is arranged in the automobile blind, and the automatic roller blind mechanism includes a rotary torsion spring and a roller blind tube. The rear end of the s...
