Because the design of current book curtain has the stay cord unit, and its draws the stay cord and the lifting rope hangs down and puts in one side of rolling up the curtain moreover for children can contact the stay cord unit easily, twine in the neck very easily at the in-process of playing, lead to accidents such as stifling, consequently current book curtain causes great safety problem to children. In addition, the rope pulling unit is often knotted or entangled, which causes inconvenience in use. Therefore, various automatic curtain rolling designs without pull ropes are available at present, which mainly use a driving motor arranged at one end of a cross rod as power, when a user presses a remote controller, the driving motor drives the cross rod to rotate, and then the curtain surface is rolled up or unfolded downwards. However, the curtain surface of the existing roller shutter including the counterweight rod at the bottom end has considerable weight, and large power is needed when the roller shutter is rolled upwards, so that a large-sized servo motor is mostly adopted as a driving motor, a set of speed reducer device is also needed to be arranged in the driving motor, and the cost of the roller shutter cannot be reduced; moreover, a large servo motor cannot be hidden in the cross bar and must be exposed at one end of the cross bar, so that the structure of the roller shutter is not simple and beautiful enough, and the automatic lifting function of all the electric roller shutters can be lost in the state of power failure or motor damage.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a retrench pleasing to the eye, low in manufacturing cost, also can realize freely going up and down under the power failure state take energy memory's electronic book curtain device.

The utility model discloses a following technical scheme realizes:

the utility model provides a take energy memory's electronic roll curtain device, take energy memory's electronic roll curtain device includes energy storage component, motor, roll axis, curtain face, fixed axle, energy storage component includes torsional spring, dead lever and linking bridge, the fixed block of torsional spring is in the linking bridge, the torsional spring with dead lever fixed connection, the dead lever runs through linking bridge with the torsional spring and with fixed axle fixed connection, be equipped with the connecting rod on the linking bridge, the connecting rod with roll axis fixed connection, rotor on the motor with roll axis fixed connection, the one end fixed connection of curtain face is in on the roll axis.

Further, be equipped with first torque arm and second torque arm on the torsional spring, be equipped with first block groove and second block groove in the linking bridge, work as the torsional spring with when the linking bridge block is connected, first torque arm accept in first block inslot, the second torque arm accept in second block inslot.

Furthermore, the electric roller shutter device with the energy storage device further comprises a pull rod, and the pull rod is fixedly connected with the bottom end of the shutter surface.

Furthermore, the electric roller shutter device with the energy storage device further comprises an accommodating pipe, and the energy storage assembly, the motor, the rolling shaft and the shutter surface are accommodated in the accommodating pipe.

The utility model has the advantages that:

the utility model provides a take energy memory's electronic book curtain device of rolling up utilizes the peculiar characteristic of variable force spring, make it at the in-process that draws to rise with the reverse elasticity of curtain face weight makes the curtain face can stop optional position in the stroke range. At the moment, only small power is added to destroy the balance between the upward elastic force and the downward gravity of the curtain surface, so that when the up-and-down height position of the curtain surface needs to be adjusted, the function of ascending or descending the curtain surface can be realized only by a motor with small power, and a set of speed reducer device and a motor with large power do not need to be arranged according to the conventional requirement; the motor and the energy storage assembly are directly combined together, so that the function of freely lifting the curtain surface can be realized in a power failure state.
