Description

CD drive

technical field

The invention relates to an optical disc drive, in particular to the structure used in the optical disc drive to make the tray cover tightly attached to the peripheral edge of the shell opening.

Background technique

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of a tray 4 and related structures in an optical disc drive 2 in the prior art. The tray 4 is used to carry an optical disk. The tray 4 passes through the opening 602 of the front shell (ie, the panel) 6 of the optical disk drive 2 to send the optical disk out and into the optical disk drive 2 .

A tray cover 8 is fixedly arranged on the side of the tray 4 outside. When the tray 4 is sent into the optical disc drive 2 to be positioned, the tray cover 8 is used to close the opening 602. In addition to being beautiful, it also prevents dust from entering the optical disc drive 2.

The so-called positioning of the tray 4 means that the optical disc on the tray 4 corresponds to an internal reading device such as an optical read-write head. However, it is because of the assembly tolerance of the optical disc drive 2 and the housing 6 , or the assembly tolerance of other internal corresponding actuating components. It is possible that when the tray cover 8 is tightly attached to the shell 6 around the hole 602, the tray 4 has not yet been positioned, which is not conducive to reading data, or if the tray 4 is forced to be positioned, its excessive pulling force will damage the tray 4 and the junction of the tray cover 8.

Or, it is possible that when the tray 4 is positioned, the tray cover 8 has not yet touched the shell 6 around the hole 602 , so holes will be left, which will not only make the tray look ugly, but also allow dust to invade the inside of the optical disc drive 2 .

In the prior art, there is a solution of using a spring to connect the tray and the tray cover, but this will produce too many independent components, which will not only hinder the assembly process arrangement, but also increase the cost.

Therefore, it is an object of the present invention to provide a structure for making the tray cover tightly attached to the periphery of the casing opening in an optical disc drive, so as to solve the above-mentioned problems.

Contents of the invention

The object of the present invention is to enable the tray cover to be properly attached to the periphery of the opening of the casing after the tray enters the optical disc drive, so that it can have both beautiful appearance and dustproof and antifouling functions. , can further enhance the value sense of the product.

Another object of the present invention is to effectively eliminate the pulling force between the tray and the tray cover when the tray enters into the optical disc drive to be positioned by an optical disc drive, so as to avoid damage caused by excessive pulling between the two.

According to the above purpose, the present invention relates to an optical disc drive, comprising a tray, an elastic structure, and a tray cover.

The tray is used to carry an optical disc, and the tray passes through the opening of the optical disc drive casing to send the optical disc into and out of the optical disc drive, wherein the side where the tray enters and exits the opening of the optical disc drive casing laterally The side is a first side.

The elastic structure includes a fixing part and two elastic arms. The fixing part is fixedly arranged on the middle section of the first side of the tray, and the two elastic arms are respectively extended from the fixing part on two different sides along the extension direction of the first side. The two elastic arms The ends that are not connected with the fixing part respectively have a hole.

The inner surface of the tray cover extends two fastening parts adjacent to two opposite ends, and the two fastening parts can correspond to the two holes. The two fastening components are respectively fastened to the holes of the two elastic arms. Through this, as long as the distance between the tray cover and the center of the tray is designed to be slightly shorter than the standard distance, when the tray enters the optical disc drive, the peripheral part of the tray cover can properly interfere with the outer casing of the opening of the optical disc drive. to close the opening.

Therefore, by using the elastic structure provided between the tray and the tray cover, the optical disc drive of the present invention can effectively absorb the pulling force between the tray and the tray cover after the tray enters the optical disc drive through the elastic deformation force of the elastic arm, and The tray cover can be appropriately and closely attached to the periphery of the opening of the casing, which can have both aesthetic appearance, dust-proof and anti-fouling functions, and can improve the value and reliability of the product.

The advantages and spirit of the present invention can be further understood through the following detailed description of the invention and the accompanying drawings.

Please refer to FIG. 2 and FIG. 3 . FIG. 2 is a schematic diagram showing the appearance and partial explosion of the optical disc drive 30 of the present invention. FIG. 3 is a schematic exploded top view of the tray 32 , the elastic structure 34 , and the tray cover 36 of the present invention. The present invention relates to an optical disc drive 30 , which includes a tray 32 , an elastic structure 34 , a tray cover 36 , and a decorative plate 38 .

The tray 32 is used to carry a CD. The tray 32 passes through the opening 4004 of the casing 40 of the CD drive 30 to send the CD out and into the CD drive 30. The tray 32 enters and exits the CD drive 30 casing 40 through the opening. The side of 4004 is a first side 3202 . Wherein, the opening 4004 is a panel 4002 located at the front end of the optical disc drive 30. When the tray 32 is put into the optical disc drive 30, the peripheral part of the tray cover 36 is the panel 4002 close to the periphery of the opening 4004 of the optical disc drive 30 to close the opening 4004. . The elastic structure 34 includes a fixing component 3402 and two elastic arms 3404 . The fixing part 3402 is fixedly arranged on the middle section of the first side 3202. The two elastic arms 3404 are formed by extending from the fixing part 3402 along the extending direction of the first side 3202 on two different sides. The two elastic arms 3404 And adjacent to the first side 3202 , the ends of the two elastic arms 3404 that are different from the connection with the fixing member 3402 respectively have a hole 3406 arranged in the front, back and horizontal direction. Wherein, the tray 32 and the elastic structure 34 are integrally formed.

Two fastening components 3602 extend from the inner surface of the tray cover 36 adjacent to two opposite ends, and the two fastening components 3602 can correspond to the two holes 3406 . The two fastening components 3602 are respectively fastened to the holes 3406 of the two elastic arms 3404 from the side of the tray 32 different from the elastic structure 34 . Through this, as long as the distance between the tray cover 36 and the center of the tray 32 is designed to be slightly shorter than the standard distance, using the deformable ability of the elastic arm 3404, when the tray 32 enters the optical disc drive 30, the peripheral portion of the tray cover 36 can be properly The shell 40 around the opening 4004 of the optical disc drive 30 is touched to close the opening 4004 . Among them, the material of the tray 32 , the elastic structure 34 , and the tray cover 36 may be, for example, POM, Nylon, or PC.

The decorative plate 38 is arranged on the outside of the tray cover 36, and can print or depict beautiful patterns, so that the outside of the tray cover 36 is more beautiful.

In addition, the hole 3406 is a through hole facing the tray cover 36 in the transverse direction, and the fastening component 3602 is an elastic structure with a barb 3602a at the end. The fastening part 3602 extends from the outside of the first side 3202 to the first side 3202 into the hole 3406, and the barb 3602a is fastened to the edge of the hole 3406 adjacent to the first side 3202, so that the fastening part 3602 is fastened. Elastic arm 3404.

To further illustrate, the fastening component 3602 includes two elastic ribs 3602b arranged side by side with a distance between them. The two elastic ribs 3602b extend from the inner side of the tray cover 36 toward the first side 3202. The ends of the two elastic ribs 3602b The opposite outer sides respectively have the aforementioned barbs 3602a.
