Embodiment

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Please refer to Fig. 2 and Fig. 3, be embodiment one of the present utility model, this rotatable CD driver device comprises rotating disk 102 and light pickup device 103, described rotating disk 102 and light pickup device 103 are positioned on the pallet 104, described pallet 104 articulates with electronic equipment 100, and in the electronic equipment 100 outside CD-ROM drive functions that realize.Like this, when needs use CD driver device, can screw out rotating disk 102 and light pickup device 103 together with pallet 104, thereby can read the data on the CD D, realize the CD-ROM drive function; When not needing to use CD driver device, pallet 104 is pivoted together with rotating disk 102 and light pickup device 103 and send into electronic equipment 100 inside, greatly reduced the shared space of CD-ROM drive.

In the present embodiment, described pallet 104 is by a rotating shaft 105 and described electronic equipment 100 inner pivot joints, in described rotating shaft 105, be arranged with a torsion spring 106, one end of described torsion spring 106 and described 100 inner connections of electronic equipment, the other end is connected with described pallet 104, and the position that described electronic equipment 100 corresponding described pallets 104 collapse in electronic equipment internal is provided with the button 119 of two spacing preiections 109 and the described spacing preiection 109 that links.Two spacing preiections 109 limit the rotation of the clockwise and counterclockwise both direction of pallet 104 respectively.Like this, when pushing button 119 the time, two spacing preiections 109 are promptly removed the constraint to described pallet 104, thereby make pallet 104 to screw out described electronic equipment 100 under the twisting force of torsion spring 106.In order to prevent the excessive rotation of pallet 104, be provided with limited post 129 in described electronic equipment 100 inner corresponding pallets 104 stowed position inboards, be provided with limited post 139 in the outside, corresponding pallet 104 working positions.And described rotating disk 102 and light pickup device 103 are electrically connected with the PCB that is positioned at electronic equipment 100 inside (Printed Circuit Board) plate 108 by lead 149,159 respectively.

Please refer to Fig. 4 and Fig. 5, be embodiment two of the present utility model, the difference of present embodiment and embodiment one is, described CD driver device also comprises the CD-ROM drive framework, and described CD-ROM drive framework comprises CD ROM baffle plate 101, is positioned at the expansion bracket 107 of described electronic equipment 100 and corresponding described CD ROM baffle plate 101 end positions setting and the base plate of fixedlying connected with described expansion bracket 107 in two ends 110 (please refer to Fig. 8).Described CD-ROM drive framework with the vertical direction of described expansion bracket 107 on be connected with described electronic equipment 100 slides within.

Please in conjunction with reference Fig. 6 and Fig. 7, described expansion bracket 107 comprises adjust case 117, be placed in described adjust case 117 and cross connecting tube assembly 127 that can be flexible with respect to described adjust case 117, press the elastic component of being located between the inner and described adjust case 117 of described cross connecting tube assembly 127 137.Described cross connecting tube assembly 127 inner downsides and described adjust case 117 articulate, and described cross connecting tube assembly 127 inner upsides and described adjust case 117 are slidingly connected.

In the present embodiment, for realizing the pivot joint of described cross connecting tube assembly 127 inner downsides and described adjust case 117, be provided with pivot 167 at described cross connecting tube assembly 127 inner downsides, described adjust case 117 correspondence positions are provided with axis hole, realize both pivot joints by the cooperation of pivot 167 and axis hole.Adopt between described cross connecting tube assembly 127 outer end downsides and the described adjust case 117 and realize in the same way articulating.

In the present embodiment, for realizing being slidingly connected of described cross connecting tube assembly 127 inner upsides and described adjust case 117, be provided with pivot 147 at described cross connecting tube assembly 127 inner upsides, the position of described adjust case 117 corresponding described pivots 147 is provided with chute 157, and the cooperation by pivot 147 and chute 157 realizes both being slidingly connected.In order to realize the locking of described expansion bracket 107 at maximum elongation shown in Figure 4 and contraction state shown in Figure 5, described expansion bracket 107 also comprises the latch-up structure (not shown) that can lock the position at described pivot 147 two ends in described chute 157.

In addition, in the present embodiment, described elastic component 137 is a volute spring, and in order to reach best stressed effect, the one end is fixed on described cross connecting tube assembly 127 inner middle parts, and the other end is fixed on the inwall of described adjust case 117 correspondence positions.

In order to reduce the volume of CD-ROM drive framework, described rotating shaft 105 is a gear shaft, the position of described base plate 110 corresponding described gear shafts be provided with can with engagement of described gear shaft and the tooth bar 120 that distributes along described CD-ROM drive framework glide direction.Like this, when described rotating shaft 105 pivots clockwise, can make the upwards slip of CD-ROM drive framework by its meshing relation with tooth bar 120.And when described rotating shaft 105 pivots counterclockwise, can make the CD-ROM drive framework to lower slider by the meshing relation of itself and tooth bar 120.Because the length of pallet 104 is greater than the CD radius, and the length of side of CD-ROM drive framework is slightly larger than cd diameter.If the CD-ROM drive framework can not slide, can successfully collapse in the electronic equipment 100 in order to make pallet 104, then the length of side of CD-ROM drive framework is required to be the twice of pallet 104 length, and this certainly will make the volume of CD-ROM drive framework increase.Therefore the CD-ROM drive framework is connected with electronic equipment 100 slides within, helps to realize the miniaturization of whole CD-ROM drive really.And cooperate cleverly by between described rotating shaft 105 and the tooth bar 120, also make the structure of whole CD-ROM drive framework be simplified.

In addition, in order to guarantee CD driver device sealing in the course of the work, present embodiment also comprises and the described electronic equipment 100 scalable first volume curtain device (not shown)s that also can hide in described CD driver device upside that are connected, also can set up and the scalable second roller blind device (not shown) that also can hide in described CD driver device downside that is connected of described electronic equipment.But described first, second roller blind device comprise respectively automatic winding the door curtain made of cloth and can with the fixing location structure of described CD ROM baffle plate 101 hooks.But the curtain of the similar of described door curtain made of cloth automatic winding in prior art, extended under the effect of external force and be fixed on location on the described CD ROM baffle plate 101 by described location structure, when taking off described location structure, can be contracted to automatically in the electronic equipment 100.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
