  • the wall 111 includes a first pivotal connection 12 and a second pivotal connection 13 opposite to the first pivotal connection 12, the lid 30 includes a first pivotal section 31 and a second pivotal section 32 extending from a circumferential edge thereof and disposed opposite to each other, and the first pivotal section 31 is mounted on the first pivotal connection 12 and the second pivotal section 32 is mounted on the second pivotal connection 13, respectively.
  • the lid 30 is pivoted automatically by a transmission assembly 20.
  • the transmission assembly 20 is mounted on an engaging section 15 of the lid engaging device 10.
  • the engaging section 15 extends outward from an outer perimeter of the wall 111 to an outer perimeter 101 of the lid engaging device 10.
  • the transmission assembly 20 includes a circuit board 21.
  • the circuit board 21 is electrically connected to an electricity supply 3.
  • the electricity supply 3 is also mounted on the engaging section 15.
  • the transmission assembly 20 also includes a motor 22 connected to the circuit board 21, a transmission member 23 driven by the motor 22 and a sensor.
  • the transmission member 23 includes a shaft 231 rotatably moved by the motor 22 and engaged in an engaging hole 33 formed in the first pivotal section 31.
  • the lid 30 is adapted to be moved between the open position and the closed position under rotation of the shaft 23.
  • the shaft 231 includes a plurality of teeth 232
  • the engaging hole 33 includes a plurality of recess engaged with the plurality of teeth 232 respectively to allow the pivoting of the lid 30 under rotation of the shaft 23.
  • the sensor is utilized to transmit electric signals to the circuit board 21 so that the circuit board 21 controls a rotational direction of the motor 22 and a rotational direction of the lid 30.
  • the sensor may be a heat-sensing device, touch-sensing device, a movement-sensing device. It is understood that all sensors are within the scope of the limitation.
  • the lid 30 includes a protrusion 34 formed on the second pivotal section 32.
  • a positing-limiting member 35 is engaged with the protrusion 34.
  • the protrusion 34 includes a connecting end 341
  • the positing-limiting member 35 includes a coupling section 351 including an aperture 354 in which the connecting end 341 is engaged in order to connect the position-limiting member 35 with the protrusion 34.
  • the position-limiting member 35 is rotated concurrently.
