Description

Disc drive

The present invention relates to a disc drive, and more particularly to a structure of a disc drive.

Generally, the recording or reproducing process of the optical disc drive is as follows: the tray feeding mechanism causes the tray to eject; after the tray carries the optical disc, the disc feeding mechanism feeds the optical disc into the optical disc drive; the optical reading head reads or writes the optical disc; After the exit or write operation is completed, the tray access mechanism ejects the tray again; to take out the disc or perform a disc change.

However, there will be some shaking during the tray loading and unloading process, such as the shaking of the tray in and out of the motor and transmitted to the tray, which will affect the smooth entry and exit of the tray.

In view of the above, it is necessary to provide a disc drive that can reduce the shaking of the tray when it enters and exits.

A disc drive comprising a tray and a frame, the tray can carry a disc and drive the disc to slide in or out of the frame to realize an inbound or outbound movement, the tray comprising a first surface and the first surface a second surface of the back, a front edge, a rear edge parallel to the front edge, a left edge, and a right edge parallel to the left edge; the front edge, the left edge, the rear edge, and the right edge are sequentially connected to form a contour of the tray; The first surface is recessed inwardly toward the front edge to form a disc accommodating area; the rack body includes a carrier and a sliding frame disposed on the carrier, the carrier includes a front end portion and a rear side opposite to the front end portion An end portion, a left side wall, and a right side wall parallel to the left side wall; the front end portion, the left side wall, the rear end portion and the right side wall are sequentially connected to form a carrier, and the sliding frame is fixed to the inner side of the front end portion; The first surface is provided with a first sliding slot parallel to the left edge, the first sliding slot is surrounded by a first partition and a second partition parallel to the left edge, the first partition is located at the left edge and the first partition Between the partitions, and an opening is provided on one end of the second partition near the front edge; a front end portion of the carrier is provided with a support portion near the left side wall; a left end of the slide frame is located on the support portion Supporting the supporting portion, the left end of the sliding frame is provided with a protrusion, the protruding portion is inserted in the first sliding slot; when the optical disk drive performs a loading or loading operation, the tray is oriented Sliding outside or inside, the protrusion sliding in the first sliding slot of the tray can guide the tray out or into the storage bin, and the left end of the sliding frame is supported on the supporting portion by the supporting portion so that the sliding frame does not downward fall.

When the above-mentioned optical disc drive is used, when the optical disc drive performs the unloading or the loading operation, the tray slides outside or inside the rack, and the protrusion slides in the first chute of the tray to guide the tray out of the bin or into the bin. It can reduce the shaking of the tray. In addition, the left end of the carriage is supported on the support portion by the support portion so that the carriage does not fall downward.

Referring to FIGS. 1 and 2, the optical disc drive 99 includes a tray 100 and a frame 200. The tray 100 is used to carry a disc (not shown), and drives the disc to slide in or out of the frame 200 to realize the loading or unloading action.

Referring to FIG. 3, the tray 100 is substantially rectangular and includes a first surface 110, a second surface 120 opposite the first surface 110 (see FIG. 4), a front edge 130, and a rear edge 140 that is parallel to the front edge 130. The left side edge 150 is a right side edge 160 that is parallel to the left side edge 150. The front edge 130, the left side edge 150, the rear edge 140, and the right side edge 160 are sequentially connected vertically to form a rectangular outline of the tray 100. The first surface 110 is recessed inwardly toward the front edge 130 to form a circular disc receiving area 112.

Referring to FIG. 4 , the second surface 120 is provided with an elongated first sliding slot 122 and a second sliding slot 124 . The first chute 122 is parallel to the left side edge 150 and is adjacent to the left side edge 150. The second chute 124 extends from the end of the first chute 122 away from the front edge 130 toward the rear edge 140 , and the second chute 124 is bent toward the left side edge 150 relative to the first chute 122 . The first chute 122 is surrounded by a first partition 1222 and a second partition 1224 that are parallel to the left side edge 150. The first partition 1222 is located between the left side edge 150 and the second partition 1224. A rectangular opening 1220 is defined in an end of the second partition 1224 adjacent to the front edge 130.

Referring to FIG. 3 , the frame 200 includes a rectangular carrier 210 and a carriage 220 disposed on the carrier 210 . The carrier 210 includes a front end portion 212, a rear end portion 214 that is parallel to the front end portion 212, a left side wall 216, and a right side wall 218 that is parallel to the left side wall 216. The front end portion 212, the left side wall 216, the rear end portion 214, and the right side wall 218 are sequentially connected vertically to form the carrier 210. A plate-shaped support portion 2120 is provided on the front end portion 212 on the side closer to the left side wall 216.

The carriage 220 is substantially elongated and is fixed to the inner side of the front end portion 212. The right end of the carriage 220 is provided with a sliding groove 222 (refer to FIG. 4). The left end of the carriage 220 is supported by the support portion 2120 on the support portion 2120, and a cylindrical protrusion 224 is provided on the left end thereof.

Referring to Figure 1, the tray 100 is slid into the frame 200 during assembly. The front edge 130 and the rear edge 140 of the tray 100 are respectively located on the front end portion 212 and the rear end portion 214 of the carrier 210 and are aligned in parallel with the front end portion 212 and the rear end portion 214. The left side edge 150 and the right side edge 160 of the tray 100 are slidably coupled in parallel to the left side wall 216 and the right side wall 218 of the carrier 210, respectively. At the same time, the protrusion 224 is inserted into the first sliding slot 122.

Referring to FIG. 5, when the optical disc drive 99 performs the unloading or loading operation, the tray 100 will slide outside or inside the frame 200 under the driving of a motor (not shown). At this time, the protrusion 224 slides in the first chute 122 of the tray 100, which can guide the tray 100 to be ejected or enter the bin while reducing the rattling of the tray 100. In addition, the left end of the carriage 220 is supported by the support portion 2120 on the support portion 2120, so that the carriage 220 does not fall downward.

In addition, when the optical disc drive 99 completes the unloading operation, the protruding portion 224 is located near the intersection of the first chute 122 and the second chute 124. Since the second chute 124 is bent toward the left edge 150 relative to the first chute 122, the protrusion 224 and the second chute 124 cooperate to prevent the tray 100 from sliding off the frame 200.

In addition, when the optical disc drive 99 completes the loading operation, the protrusion 224 is located at the opening 1220 of the second partition 1224 of the first sliding slot 122, and the protruding portion 224 can be removed and moved into the first sliding slot 122 through the opening 1220. Thereby, the carriage 220 can move left and right with respect to the front end portion 212 of the carrier 210.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
