Abstract
A lid opening and closing device includes a base, a lid, an arm that has a pivoting part and an engagement portion and is movable between a retracted position and an advanced position, a rotating body that moves the arm by a driving force received from a drive source, a locking member that is rotatable between a lock position and an unlock position when the arm is in the retracted position, a cam that rotates the locking member toward the unlock position when the arm is moved to the advanced position, and a differential mechanism that starts rotating the pivoting part after a delay from the start of rotation of the rotating body when the arm is moved to the advanced position.
Claims9
A lid opening and closing device comprising:
- a base disposed in an inner side of a receiving port of a panel;
- a lid that openably close the receiving port;
- an arm including a pivoting part on one end side of the arm and pivotally supported by the base, a continuous portion on another end side continuous with the lid, and an engagement portion provided to the pivoting part, the arm being movable between a retracted position where the arm is retracted within the panel to close the receiving port by the lid and an advanced position where the arm is protruding out through the panel to open the receiving port;
- a rotating body that transmits a driving force received from a drive source to the pivoting part to move the arm between the retracted position and the advanced position;
- a locking member pivotally supported by the base to be adjacent to the pivoting part, the locking member being rotatable about a rotation axis extending along a rotation axis of the pivoting part between a lock position in which the locking member is engaged with the engagement portion and an unlock position in which the locking member is disengaged from the engagement portion when the arm is in the retracted position;
- a cam that is rotatable in conjunction with the rotating body and transmits a rotational force of the rotating body to rotate the locking member in the lock position toward the unlock position when the arm in the retracted position is moved to the advanced position;
- and
- a differential mechanism that starts rotation of the pivoting part after a delay from start of rotation of the rotating body when the arm in the retracted position is moved to the advanced position.
