Abstract

The utility model relates to an electronic self-balancing door/window curtain comprising an upper beam, a lower beam, separating strips, a group of light shielding elements and a drive device, wherein both ends of each separating strip are rigidly connected with the upper beam and the lower beam, the light shielding elements are connected sequentially between the separating strips by a plurality of pull ropes. The upper beam is of a hollow structure and is provided with a plurality of rope rolling devices, a bearing and a bearing seat for supporting the rope rolling devices. A conic balance wire-collecting device wound with a balance pull wire is used for connecting the drive device, the rope rolling devices and the transmission shaft of the conic balance wire-collecting device. The small-diameter end of the conic balance wire-collecting device is provided with a positioning pin to stop the drive device when the balance pull wire meets the positioning pin. One end of the balance pull wire is fixed at the large-diameter end of the conic balance wire-collecting device, and the other end is connected with a constant force spring by a constant force spring seat. The inner ring of the constant force spring is connected with the constant force spring seat, and the outer ring is fixed on one separating strip by a rivet. The utility model not only can cause a person to pull a door/window with little effort but also can effectively reduce the motor power consumption and the appearance size.

In the middle of the Modern Family, window forms such as electric-powered shutter, shutter curtain and rolling door are widely adopted.This class door and window generally all is to drive a spool by micromachine the stay cord of door and window is reeled on spool, thereby door and window is risen or decline.This door and window is drawing high in the middle of the process, because frictional force increases, needed pulling force constantly increases along with the increasing that draws high height, and the plastics ropewinder is worn easily, also need to be equipped with more powerful motor for it, not only power consumption is big but also motor volume is big, makes that the outward appearance of door and window is attractive in appearance inadequately, needs the allocation position sensor to realize the upper limit and the lower limit of curtain simultaneously.
Summary of the invention
The utility model is intended to solve the problems of the technologies described above, and a kind of lifting/lowering device of self-neutralization door and window is provided.The utility model lifting/lowering device of self-neutralization door and window can not only make the people spur door and window effortlessly, and can effectively reduce motor power consumption and appearance and size, and is simple in structure, with low cost.
The utility model is achieved in that a kind of electronic self-neutralization door and window curtain, one group of shade and drive unit that it comprises upper beam, underbeam, two ends and the rigidly connected parting bead of last underbeam and is horizontally disposed with between them and is connected in turn with some stay cords; Described upper beam is a hollow structure, inside is provided with some ropewinders, some bearings and bearing support are in order to support ropewinder, a taper balance spooler that is wound with the balance backguy, and the power transmission shaft in order to connection drive unit, ropewinder and taper balance spooler;
The smaller diameter end of described taper balance spooler is provided with an alignment pin so that the balance backguy when running into this alignment pin drive unit quit work;
One end of described balance backguy is fixed on the larger diameter end of taper balance spooler, and the other end is connected with constant force spring by a constant force spring seat, and this constant force spring inner ring connects the constant force spring seat, and the outer ring is fixed on the parting bead by rivet.
Described electronic self-neutralization door and window curtain, it also comprises a ladder rope switching mechanism that is sleeved on the power transmission shaft, it mainly comprises a turnover spring and ladder rope retainer ring near bearing that is sleeved on the power transmission shaft, the two ends of this turnover spring are free end and can rotate under the driving of power transmission shaft, and ladder rope retainer ring is driven by turnover spring; Described bearing support comprises the base of a frame type and is connected on the base one in order to hold the ring set of bearing that this ring set is provided with two limited blocks with certain width to limit two free-ended rotational angles of described turnover spring near two link position places of turnover spring one side bottom and base.
Described electronic self-neutralization door and window curtain, described drive unit comprises motor and control circuit board.
Described electronic self-neutralization door and window curtain, described drive unit comprises a magnetically-actuated mechanism.
The utility model utilizes conical winding shaft, is in the different-diameter position different moment of generation by the stay cord that changes balancing weight and comes the different loading moment of balance, the friction when utilizing bearing to reduce the rotation of taper spool.The stay cord that utilizes the move left and right of screw rod to guarantee to connect balancing weight when the taper spool rotates is in the diametrical position of needs, utilizes assembly pulley to reduce friction simultaneously.When this type of door and window was installed in hollow glass the inside or the left and right sides and is provided with guide rail, when moving up and down in order to reduce shade and the friction of guide rail or glass, the shade feeder can be neat the piling up of shade, discord guide rail or glass contact.
