Description

Against shock pallet bearing structure

Technical field

The present invention relates to a kind of against shock pallet bearing structure, relate in particular to the against shock pallet bearing structure in a kind of CD-ROM device.

Background technology

CD-ROM device is one of modal information peripheral equipment, and it can be to be installed in the personal computer, also can in be built in many television appliances for example DVD or VCD player.The major function of CD-ROM device is exactly to read data stored in the various optical storage medias.

In order to read the data in the various optical storage medias faster, the manufacturer of CD-ROM device and CD-ROM device chip manufacturer there's no one who doesn't or isn't accelerate CD-ROM device and read multiple, realize the purpose that reads fast.On the other hand, the degree of stability of the various performances on the CD-ROM device also is another emphasis.For example, the various mechanism stability of CD-ROM device.

In the use of CD-ROM device, before CD-RW discsCD-RW is not also fixed by the rotating shaft of motor and begun to rotate, be to utilize pallet temporarily to carry CD-RW discsCD-RW.In addition, pallet also has the function of CD-RW discsCD-RW being sent and withdrawed to CD-ROM device, puts into or take out the function of CD-RW discsCD-RW for the user.Normally utilize motor driven to place pallet on the slide rail, carry out the action of sending and withdraw from pallet to, realizing the function of sending and withdraw from CD-RW discsCD-RW to of pallet, when pallet is withdrawn into the terminal point of slide rail, washer can block slide rail and make no longer outward movment of pallet.Yet original inertia of pallet and the motor that does not stop to move often make washer bump slide rail, and modal problem is exactly that pallet can clash into vibrations about slide rail because of washer.Therefore, the manufacturer of CD-ROM device need propose the problem that suitable solution overcomes above-mentioned pallet vibrations.

Summary of the invention

At above-mentioned defective, the object of the invention is, the against shock pallet bearing structure in a kind of CD-ROM device is provided, and transmits the vibrations that produced in the process of CD-RW discsCD-RW in order to reduce pallet.

According to above-mentioned purpose of the present invention, a kind of against shock pallet bearing structure of CD-ROM device is proposed, be applicable in the CD-ROM device, this against shock pallet bearing structure comprises a pallet at least, the tray bottom has two chutes, and the slide rail that is used for carrying this two chute, also comprises a shell fragment that is arranged at the slide rail side, this shell fragment nestles up slide rail, to provide against shock required elastic force.

According to a preferred embodiment of the present invention, above-mentioned slide rail and shell fragment are by the manufacturing of plastics ejection formation.In addition, shell fragment also can be the shell fragment of metal material.

From the above, use the against shock pallet bearing structure in the CD-ROM device of the present invention, can significantly reduce pallet because of washer bump slide rail produce about vibrations.In addition, shockproof structure penetrates one-body molded mode with plastics and makes, and can effectively reduce the production cost that increases behind the shell fragment.

Embodiment

Hereinafter, will describe the present invention in detail.

The problem to be solved in the present invention is that pallet transmits in the process of CD-RW discsCD-RW the vibration problems that is produced.In an embodiment of the present invention, propose the against shock pallet bearing structure in a kind of CD-ROM device, be used for reducing in the process of pallet transmission CD-RW discsCD-RW, pallet can clash into the situation of vibrations (rocking) about slide rail because of washer.

Please refer to Figure 1A, it is the vertical view of the CD-ROM device of a preferred embodiment of the present invention.This CD-ROM device 10 is by pallet 16, CD-RW discsCD-RW is sent or is withdrawed to CD-ROM device 10, the limit, left side 17 of pallet 16 and the back side of right edge 15 have the chute (not shown) respectively, and the slide rail that is used for carrying this chute, this chute and slide rail engaging can provide the dragging track of pallet 16 1 low-frictional forces, just can carry out the action of CD-RW discsCD-RW being sent or withdrawed to CD-ROM device 10 by the driving of motor again.Present embodiment is the limit, left side 17 of being close to pallet 16 by shell fragment 14, and the elastic force that utilizes shell fragment 14 to provide engages chute and slide rail closely, is difficult for producing vibrations.

Please refer to Figure 1B, it is the enlarged drawing of overlooking of the against shock pallet bearing structure of a preferred embodiment of the present invention.Figure 1B is Figure 1A circular dashed line 30 enlarged drawing partly.What specify is, the surface of contact 21 on the limit, left side 17 of shell fragment 14 and pallet 16, and minimizing contact area painstakingly can reduce the friction force of 16 on shell fragment 14 and pallet.And the minimizing of contact area can't reduce the elastic force that shell fragment 14 will impose on limit, pallet 16 left side 17.

Please refer to Fig. 2 A, it is the structural drawing of the CD-ROM device of a preferred embodiment of the present invention.This figure is the structural drawing after CD-ROM device 10 is got rid of pallet.Therefore, the significant components of many CD-ROM device 10 for example is used for reading the motor and the gear set 18 of the optical read/write head 29 of CD-RW discsCD-RW, the CD-RW discsCD-RW drive unit 27 that is used for fixing and rotates CD-RW discsCD-RW and driving tray.Wherein against shock pallet bearing structure comprises slide rail 12, slide rail 22 and shell fragment 14.Please refer to Fig. 2 B, it is a kind of against shock pallet bearing structure structure enlarged drawing partly of a preferred embodiment of the present invention.Fig. 2 B is Fig. 2 A circular dashed line 40 enlarged drawing partly, its clearer spatial structure of depicting slide rail 12 and shell fragment 14.

Please refer to Fig. 3, it is the sectional view of the against shock pallet bearing structure of a preferred embodiment of the present invention.This sectional view is the sectional view that cuts gained among Figure 1A from A-A ' profile line.The outer wall 20 that comprises limit, left side 17, chute 19, slide rail 12, shell fragment 14 and the CD-ROM device of pallet among the figure.In preferred embodiment of the present invention, shell fragment 14 is to be made by the plastics ejection formation.In order to reduce cost, the outer wall 20 of slide rail 12, shell fragment 14 and CD-ROM device all designs in advance when the die sinking of plastics ejection formation and interconnects.So increasing a shell fragment 14 costs just almost is the cost of plastics ejection formation die sinking.In addition, shell fragment 14 also can use other material, for example metal clips.

By the invention described above preferred embodiment as can be known, use the against shock pallet bearing structure in the CD-ROM device of the present invention, can significantly reduce pallet because of washer bump slide rail produce about vibrations.In addition, shockproof structure penetrates one-body molded mode with plastics and makes, and can effectively reduce the production cost that increases behind the shell fragment.

Be understandable that; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection domain of accompanying Claim of the present invention.
