Abstract
A mechanism cooling the stepping motor of optical disc actuator automatically consists of tray and sir guide component set on tray at position corresponding to said stepping motor. It is featured as using said air guide component to guide air stream brought in by optical disc to said stepping motor to bring high temperature heat generated during operation of stepping motor away by said air stream for cooling stepping motor automatically.
Description
Technical field
The relevant CD drive of the present invention, the cooling body of the step motor of especially relevant CD drive.
Background technology
See also shown in Figure 1.In the CD drive running, optical read/write head is sought rail by the step motor 20 of pallet 10 belows and is read and write data, and under using for a long time, can cause step motor 20 bodies to produce heat of high temperature.The step motor 20 of inferior quality is easier to produce heat of high temperature, though quality preferably step motor more can not produce heat of high temperature, its cost is higher.When step motor 20 temperature are too high, will cause the undesired or damage of its function.
CD drive is when running, and discs can drive strong air flow and flow because run up.No. the 242830th, the novel patent in the Taiwan that the applicant has got permission, disclose a kind of disc drive appts, comprise a disc bearing pallet, in order to hold disc, have a disc and hold recess, this disc holds recess and has surface, an inside edge, and this surface, inside edge is in comprising an inclined-plane with respect to one of this disc bearing pallet on axially, air-flow in order to this disc bearing pallet of will flowing through is directed to one in order to drive the step motor of optical devices, makes the step motor cooling to utilize this air-flow.But the inclined-plane air-guiding of this pallet flows slightly downwards, and only by small part air flow direction step motor, it makes the step motor cool effect limited.
Summary of the invention
In order further to make pallet have better diversion function, make step motor obtain better cooling effect, and propose the present invention.
Fundamental purpose of the present invention provides a kind of mechanism of automatic cooled disk driver step motor, makes step motor obtain better cooling effect.
Another object of the present invention provides a kind of mechanism of automatic cooled disk driver step motor, does not need extra increase cost, just can make step motor reduce temperature, promotes its usefulness.
Another purpose of the present invention provides a kind of mechanism of automatic cooled disk driver step motor, and is more flexible when making CD drive apolegamy step motor, can save the manufacturing cost of CD drive.
A kind of mechanism of automatic cooled disk driver step motor, the air-flow guiding step motor that drives when the discs in the CD drive is rotated, described mechanism comprises a pallet, this pallet has a gas guiding component corresponding to the position of this step motor top, so that the air-flow that discs drove is guided by this gas guiding component, blow to this step motor, the heat of high temperature that produces when making this step motor work is taken away by this air-flow.
Adopt the solution of the present invention not need other costs of ancillary cost, just can reach the effect of more effective cooling step motor, and more flexible when making CD drive match step motor, can save the manufacturing cost of CD drive.
Other purposes of the present invention, effect see also drawings and Examples and are described in detail as follows.
Description of drawings
Fig. 1 is that the pallet of well-known optical disk drives and the position of step motor concern synoptic diagram.
Fig. 2 is that the pallet of CD drive of the present invention and the position of step motor concern synoptic diagram.
Fig. 3 drives the synoptic diagram that flows to of air-flow when rotating for the video disc of CD drive of the present invention.
The air-flow that Fig. 4 drives when rotating for the video disc of CD drive of the present invention is directed to the schematic side view of step motor.
Embodiment
See also shown in Fig. 2,3,4.The mechanism of automatic cooled disk driver step motor of the present invention comprises a pallet 30, and a side of the perforate 300 of this pallet 30 has a gas guiding component 31 corresponding to the position of step motor 40 tops.This gas guiding component 31 has an inclined-plane 311 that tilts downwards, as shown in Figure 4, so that discs 50 is held disk 60 and Spindle Motor 70 corresponding ironwares and magnet clamping, and during by Spindle Motor 70 driven rotary, the air-flow 51 that this discs 50 is driven is by inclined-plane 311 guidings of gas guiding component 31, blow to step motor 40, the heat of high temperature that produces when making step motor 40 work is taken away by air-flow 51, and reaches the effect of more effective cooling step motor 40.
The present invention's air-flow that guiding is driven under running up by discs by gas guiding component; make air-flow skim over the step motor body and take away heat its temperature is reduced; can solve CD drive under operating state; step motor can produce heat of high temperature and cause the dysfunction or the problem of damage; and more flexible when making CD drive apolegamy step motor, can save the manufacturing cost of CD drive.
The present invention can do design alteration with having pallet now, further the air-flow that discs is driven is directed to the step motor body, make the air-flow that this air-flow becomes provides heat radiation, to keep lower step motor operating temperature, make the characteristic of step motor produce less variation, therefore can promote its usefulness, and keep preferable running quality.And the present invention does not need other costs of ancillary cost yet, in other words, is exactly under present cost, utilizes the pallet with air guide, just can make the temperature reduction of step motor and promote its usefulness.
The above record, only for utilizing the embodiment of the technology of the present invention content, any personnel that are familiar with this technology use the change or the replacement of all equivalences that the present invention done, and all belong to the claim that the present invention advocates, disclose and be not limited to embodiment.
