Description

The opposite opened electrically driven curtain

Technical field

The present invention relates to a kind of electrically driven curtain, especially refer to a kind of opposite opened electrically driven curtain automobile-used, that have left and right sides automatic open close.

Background technology

Automobile-used curtain can be used to sunshade and block vision, to increase occupant's comfort level, its importance is also paid attention to gradually widely, and existing curtain can be divided into two kinds of hand and electrodynamic types, at present, domestic more common opposite opened vehicle manual window shade arrangement is on the rear window top of automobile and curtain rail is installed in the bottom, casement is contained on the guide rail with slide block, draws back or close curtain with manual manipulation mode, and is simple in structure, attractive in appearance because of it, but it is regulated at will light again, and more welcome.But its shortcoming is: during operation, must stand up and can not finish with general sitting posture, and from its occupant far away under the situation that arm can't touch, could operate the curtain of rear window after must getting off, therefore, use extremely inconvenient.For this reason, people design the electrodynamic type curtain, as the patent No. is the Chinese utility model " a kind of Vehicular electric curtain " (notification number is CN2510333Y) of ZL01271318.X, it comprises transmission mechanism, thread spindle mechanism, abat vent device and screw thread flexible axle, be equipped with the steel disc hitch on the screw thread flexible axle, one end of hitch revolves and is equipped with a steel disc nut, during use, big pinion by two pairs of mutual transmissions, the power of motor is transferred on the screw thread flexible axle, when motor clockwise or when rotating counterclockwise, revolve the steel disc nut of putting on the screw thread flexible axle also corresponding in tube seat to the right or be moved to the left, thereby drive abat vent or be moved to the left to the right.Therefore, it has solved above-mentioned defective well, but because it adopts the screw thread flexible axle, after use a period of time, the flexible axle easy deformation, and make nut on the screw thread flexible axle, to slide flexibly; Moreover, because the shape of vehicle rear window is trapezoidal, can open completely and close in order to make window curtain fabric, the velocity of rotation of screw thread flexible axle becomes certain ratio about must making, and satisfy such requirement, must have the big pinion of the different couplings with two pairs of at least two motors just to be accomplished, therefore, electrically driven curtain complex structure like this, the manufacturing cost height, and influenced its use.
