1. An electrically-operated umbrella, comprising:
a column, being hollow;
an upper tray attached to a top of the column;
a lower tray slidably fitted onto the column;
a plurality of ribs movably connected to the upper tray;
a plurality of stretchers movably connected to the lower tray; and
a rope extending inside the column;
wherein,
the lower tray is capable of sliding upward and downward along the column;
each rib is rotatably hinged to the upper tray, and one end of each stretcher is hinged to the lower tray, while an opposite end of each stretcher is hinged to each rib, forming an umbrella frame;
a housing is attached to a lower portion of the column;
a through hole for receiving the rope shaft is radially disposed in the lower portion of the column;
a rotatable rope shaft, a motor for rotating the rope shaft, and a transmission mechanism are placed inside the housing;
the rope shaft is traversely disposed across the column through a plurality of fixation seats;
one end of the rope is connected to the rope shaft, and the other end of the rope runs upward through the upper tray inside the column and then runs downwardly to connect to the lower tray;
a battery and a circuit board are further disposed inside the housing, and a control button connected to the circuit board is disposed on the housing to form a control circuit of the motor;
the plurality of fixation seats is composed of a left fixation seat and a right fixation seat, which are symmetrically disposed on left and right sides of the column, a plurality of connecting holes is formed on upper and lower sides of the fixation seats, and the plurality of fixation seats is fixed to the column through a plurality of connecting members;
a circular hole for receiving the left end of the rope shaft is formed in the middle of the left fixation seat, and a shaft seat for fixing and rotating the right end of the rope shaft is formed in the middle of the right fixation seat;
the right end of the rope shaft passes through the column to be inserted into the shaft seat of the right fixation seat, while the left end of the rope shaft passes through the middle column to be inserted into the circular hole of the left fixation seat and is connected to the transmission mechanism;
the transmission mechanism comprises a transmission box, and a planetary pear set, a first spur gear and a second spur gear disposed in the transmission box, the second spur gear being smaller than the first spur gear;
the transmission box comprises a transmission box seat and a transmission box cover;
the transmission box seat is disposed on a left side of the left fixation seat, a first end of the transmission box seat is fixed to the left fixation seat, and a mounting cylinder for receiving the planetary gear set is convexly disposed at a second end of the transmission box seat;
the transmission box cover is disposed at a right opening of the mounting cylinder of the transmission box seat;
the motor is fixedly mounted on the transmission box cover, and a motor shaft passes through the transmission box cover and is connected to the planetary gear set; and
an end of the planetary gear set is connected to the second spur gear through an output shaft.
