Description
Technical field:
The utility model relates to the computer equipment technical field, refers in particular to the gearing in the optical disc drives such as a kind of CD-ROM of being applied to, DVD-ROM, DVD-RW.
Background technology:
Optical disc drive is important external memory storage in the computer equipment, and in today of computer develop rapidly, it has become imperative equipment in the host computer.Present its mode of operation of light butterfly driver is mostly identical, promptly by the laser disc support with among the CD loading equipment, the laser head support rises from bottom to top then, and by install with the laser head support on pallet CD is held up, and the beginning high speed rotating, meanwhile laser head begins along guide rail operation and reads data on the laser disc.The laser head support lift or drop movements is that gearing in one optical disc drive is realized.But the transmission structures too complex of present optical disc drive inside, it generally adopts two groups of gears at least, one group of gear drive laser disc support wherein, and another group gear driven actuator, so just make that the gear utilization is more relatively, and too much driving member can make the underaction of transmission change and stablize, and makes interior this of optical disc drive seem crowded all the more with regard to narrow space.
Summary of the invention:
The purpose of this utility model be to provide a kind of simple in structure, stable, can be applicable to the gearing in the optical disc drives such as CD-ROM, DVD-ROM, DVD-RW.
The utility model is achieved by the following technical solution: this device comprises driving gear set, actuator and the laser disc support that is arranged on the main body rack, actuator by the chute inlay card offered on it on main body rack, and its side is provided with gathering sill, the laser disc support along the slide rail inlay card on main body rack, it is characterized in that: driving gear set comprises: motor wheel, belt pulley and duplicate gear, and the belt pulley and the duplicate gear that drive by motor wheel mesh; One end of actuator be connected with one can with the tooth bar of duplicate gear engagement, also be provided with a guidepost on it; The laser disc cradle back be provided with a guide groove and one can with the tooth bar of duplicate gear engagement.
After adopting this structure, being provided with on actuator can be directly and the tooth bar of duplicate gear engagement, and duplicate gear drives laser disc support and actuator simultaneously, has so just saved one group of gear, simplifies the structure, and makes its structural design more reasonable.

Embodiment:
See accompanying drawing 1,2,3,4,5, the utility model comprises: driving gear set 2, actuator 3 and laser disc support 4.It is installed on the main body rack 1, and wherein on main body rack 1, laser disc support 4 back sides are provided with chute 43 to actuator 3 by chute 31 inlay cards offered on it, and by this chute 43 along slide rail 11 inlay cards on main body rack 1.
The side of actuator 3 is provided with two and is
The gathering sill 30 of shape.Driving gear set 2 comprises: motor wheel 21, belt pulley 22 and duplicate gear 23, belt pulley 22 drives by motor wheel 21, and gear wheel 231 engagements on the belt pulley 22 in an affixed pinion wheel 221 and the duplicate gear 23, one end of actuator 3 also is connected with a tooth bar 32 that can mesh with the pinion wheel 232 on the duplicate gear 23, also is provided with a guidepost 33 on it; Laser disc support 4 back sides be provided with a guide groove 42 and one can with the tooth bar 41 of 232 engagements of pinion wheel on the duplicate gear 23.
Also be provided with a draw-in groove 34 on the actuator 3, the elastic dialing rod 35 that is installed on the main body rack 1 is positioned at draw-in groove 34, stirs draw-in groove 34 by elastic dialing rod 35, makes actuator 3 be in a kind of trend that resets, and makes the chute of actuator 3 be unlikely to break away from main body rack 1.
During the utility model work, driving belt pulley 22 by motor wheel 21 rotates, and driving the gear wheel 231 of duplicate gears 23 by the pinion wheel on the belt pulley 22 221, the pinion wheel 232 by duplicate gear 23 drives laser disc supports 4 along guide rail 11 operations then, makes laser disc support 4 enter or withdraw from.See accompanying drawing 1,6, when laser disc support 4 with the CD loading equipment among, laser head support 5 will rise under the drive of interlock plate 6 from bottom to top, and by install with laser head support 5 on pallet 51 CD is held up, and beginning high speed rotating, laser head 52 beginning meanwhile is along guide rail 53 operations and read data on the laser disc, how the uphill process that specifies laser head support 5 is below realized, laser head support 5 two ends be connected on the cylinder support 1 by elastic component 7 respectively and web joint 6 on, and web joint 6 by bearing pin 61 inlay cards that extend on its dual-side on main body rack 1, web joint 6 can rotate up and down around bearing pin 61 like this, and web joint 6 also will drive and connect thereon that an end of laser head support 5 upwards lifts or falls when rotating.End at web joint 6 is provided with two axis of guides 62, and these two axis of guides 62 just in time place in the gathering sill 30 on the actuator 3, because gathering sill 30 is
Shape so when actuator 3 move left and right, the axis of guide 62 on the web joint 6 will promote the track that lower edge gathering sills 30 are provided with at gathering sill 30 and move, is thus connected plate 6 and can be directed to groove 30 and lifts or fall.Thereby driving laser head support 5 lifts or falls.And actuator 3 realizes that the mode of move left and right is: when laser disc support 4 access arrangements, at first by motor driven driving gear set 2, pinion wheel 232 in the duplicate gear 23 will clockwise rotate, see accompanying drawing 1, laser disc support 4 will move in equipment by pinion wheel 232 and its tooth bar 41 this moment, after moving to certain distance, the guide groove 42 that this moment, laser disc support 4 back sides were provided with just in time walks to the axis of guide 33 places on the actuator 3, laser disc support 4 moves on, drive the axis of guide 33 along guide groove 42 operations, thereby drive actuator 3 beginnings operation to the right, after actuator 3 moves a segment distance to the right, tooth bar 32 beginnings and pinion wheel 232 engagements continue to move right thereby drive actuator 3 by pinion wheel 232.Enter back motor wheel 21 fully until laser disc support 4 and shut down, and web joint actuator 3 drives 6 this moment have been lifted under actuator 3 drives, and laser head support 5 lifts simultaneously, makes pallet 51 hold up the CD entry into service that is placed on the laser disc support 4.Otherwise when laser disc support 4 withdrawed from, its mode of motion was with above-mentioned opposite.
The utility model is provided with on actuator 3 can be directly and the tooth bar 32 of duplicate gear 23 engagements, and duplicate gear 23 drives laser disc support 4 and actuator 3 simultaneously, so just saved one group of gear, simplifies the structure, and makes its structural design more reasonable.
