Adjustment mechanism for optical pickup head of optical disk drive
View Patent ↗An optical disk drive including a case, a traverse, a guide rod, an optical pick-up head and at least a locking member is provided. The traverse is disposed in the case and includes at least a cantilever part and at least a locking hole. The cantilever part protrudes from a carrying surface of the traverse and is integrated with the traverse. The guide rod leans against a bearing end of the cantilever part. The optical pick-up head is slidably disposed on the guide rod. The locking member includes a leaning part and a locking part. The locking part is locked into the locking hole and the leaning part presses an upper side of an end of the guide rod for making the bearing end generate a bending displacement toward the carrying surface through the guide rod.
1. An optical disk drive, comprising:
a case;
a traverse, disposed in the case and comprising at least a cantilever part and at least a locking hole, wherein the cantilever part protrudes from a carrying surface of the traverse and is integrally formed with the traverse;
a guide rod, disposed above the cantilever part and leaning against a bearing end of the cantilever part;
an optical pick-up head, slidably disposed on the guide rod; and
at least a locking member, comprising a leaning part and a locking part, wherein the locking part is locked into the locking hole and the leaning part disposes above the guide rod and presses an upper side of an end of the guide rod for making the bearing end generate a bending displacement toward the carrying surface through the guide rod.
2. The optical disk drive according to claim 1 , wherein the bearing end comprises a plane, and the guide rod leans against the plane.
3. The optical disk drive according to claim 2 , wherein another end of the guide rod is fixedly disposed on the traverse.
4. The optical disk drive according to claim 1 , wherein the traverse comprises a barrier wall surrounding the locking hole, used for forming a containing space above the locking hole to receive the leaning part of the locking member, and the barrier wall comprises an accommodating opening for receiving the end of the guide rod; the end of the guide rod is adapted to moving along a direction perpendicular to the carrying surface in the accommodating opening.
5. The optical disk drive according to claim 4 , wherein at least a part of the bearing end is located in the accommodating opening.
6. The optical disk drive according to claim 1 , wherein an extending direction of the cantilever part is parallel to an axial line of the guide rod.
7. The optical disk drive according to claim 1 , wherein the locking member and the locking hole are respectively a screw and a screw hole.
8. The optical disk drive according to claim 2 , wherein the plane is parallel to the carrying surface.
9. The optical disk drive according to claim 8 , wherein the cantilever part has an inclined surface for connecting the carrying surface and the plane.
