Stopper for preventing the separation between the traverse and the traverse frame in an optical disc drive
View Patent ↗The present invention discloses an optical disk drive comprising a traverse, a traverse frame, a chassis and a stopper. The traverse frame is disposed on the chassis. And one end of the traverse is disposed on the chassis and the other end is disposed on the traverse frame. The stopper includes a protruded arm and an extended arm extended from the protruded arm. The protruded arm is integrated with the traverse by sheet metal forming and the extended arm is disposed above the traverse frame. The extended arm of the stopper is interfered with the traverse frame when a heavy shock is applied to the optical disk drive. Therefore, the optical disk drive including the stopper can prevent the separation between the traverse and the traverse frame without screws when a sudden hit is applied thereto.
1. An optical disk drive comprising:
a chassis;
a traverse frame having a first flange moveably connected to the chassis;
a traverse having a second flange, wherein one end of the traverse is disposed on the chassis and the other end is disposed on the traverse frame;
a damper having two separate necks, wherein the two separate necks of the damper are clamped on the first and the second flanges, respectively;
an optical pickup head disposed on the traverse for reading and/or writing information on an optical disk;
a motor disposed on the traverse for moving the optical pickup head;
a spindle motor disposed on the traverse for supporting and rotating the optical disk; and
a stopper comprising a protruded arm formed with the traverse and an extended arm extended from the protruded arm, wherein the protruded arm is protruded from the traverse and the extended arm is disposed above the traverse frame,
wherein the extended arm of the stopper is interfered with the traverse frame under a heavy shock.
2. The optical disk drive according to claim 1 , wherein the stopper is a L-shaped structure and the extended arm is perpendicular to the protruded arm.
3. The optical disk drive according to claim 1 , wherein the protruded arm is bended downward and is perpendicular to the traverse.
4. The optical disk drive according to claim 1 , wherein the protruded arm is bended upward and is perpendicular to the traverse.
