The present invention relates to a disk drive, and more particularly, to a vibration and deformation prevention structure of a disk drive for loading and unloading a disk while moving relative to the main base.

1 is a plan view showing the configuration of a disk drive according to the prior art, Figure 2a is a perspective view showing a state before the tray is coupled to the vibration and deformation prevention structure of the disk drive according to the prior art, Figure 2b is a prior art Figure 2 is a perspective view showing a state in which the tray is coupled to the vibration and deformation prevention structure of the disk drive.

According to this, both ends of the main base 1 serving as a skeleton of the disc drive are formed long before and after the side wall 2 to have a predetermined height. A rear side wall 3 connecting the side walls 2 is formed at the rear end of the main base 1. A plurality of guide bosses 4 for guiding the movement of the tray 7 to be described below are formed at both ends of the upper surface corresponding to the inside of the side wall 2 of the main base 1.

On the bottom surface of the main base 1, a driving unit (not shown) including a loading motor providing a driving force for entering and exiting the tray 7 into and out of the drive is provided. This drive unit is composed of a plurality of gears and belts, the driving force is finally transmitted to the loading gear (1a).

A height regulating rib 5 is formed on the inner surface of the side wall of the main base 1 so as to extend in a direction facing each other in the horizontal direction. The height regulating rib 5 restricts both sides of the upper end of the tray 7 to prevent the tray 7 from excessively flowing upward with respect to the main base 1.

And the upper surface of the main base (1) adjacent to the rear wall (3) is provided with a boss (6) for preventing the flow of the tray (7) to minimize the noise and vibration caused by the rotation of the disk. This boss portion 6 fits into the rib 9 formed in the cutout 8 of the tray 7 which will be described later. Therefore, since the tray 7 is elastically coupled to the main base 1 by the boss 6, the widthwise vibration of the tray 7 is minimized.

The tray 7 is installed on the upper surface of the main base 1, and loads and unloads a disk while moving back and forth with respect to the main base 1. At this time, a rack gear 7a meshed with the loading gear 1a is provided at one side of the lower surface of the tray 7 in the longitudinal direction of the tray 7. In addition, guide channels (not shown) into which guide bosses 4 of the main base 1 are inserted are formed at both ends of the lower surface of the tray 7.

The disk seating surface 10 on which the disk is seated is formed on the upper surface of the tray 7. A door mounting hole 11 is formed at the tip of the tray 7, and a door 12 is mounted at the door mounting hole 11 as indicated by a dotted line in FIG. 1. The door 12 is installed at the front of the tray 7.

Meanwhile, in order for the tray 7 to move smoothly with respect to the main base 1, between the guide boss 4 and the guide channel, and between the height regulating ribs 5 and the upper surface of the tray 7. Requires a predetermined gap.

And at the rear end of the tray 7 is formed a cutout portion 8 which is partially cut in the longitudinal direction. The cutout portion 8 is elastically deformed at approximately the center of the cutout portion 8 so as to correspond to the thickness of the boss portion 6 so that the boss portion 6 of the main base 1 can be detachably fitted. Possible ribs 9 are constructed. Therefore, when the tray 7 is loaded, the boss part 6 is fitted into the rib 9 formed in the cutout part 8, thereby preventing vibration in the width direction.

In the figure, reference numeral 13 denotes a clamp bracket, and 14 denotes a clamp for holding a disk seated on a turntable.

However, the prior art as described above has the following problems.

In other words, the disk may be in a state in which there is an uneven load in the manufacturing process, and when the unloaded disk is mounted on the tray 7 and rotates at a high speed, the disk may have a width and height direction flow in the tray 7. In addition, the tray 7 may flow due to an impact applied during the movement of the disk drive.

By the way, in the prior art, only the boss portion 6 for regulating the widthwise flow as shown in Fig. 2b is provided. Therefore, the related art does not regulate the flow in the height direction of the tray 7 has a problem that the noise and vibration of the disk drive is maintained.

In recent years, the technology has been developed in the direction of lowering the overall height of the disk drive by having a slim tray (7). However, the slimmed tray 7 is thin and its weakness is found such that bending deformation occurs in high temperature conditions. That is, as shown in Figures 3a and 3b, the tray 7 is caused to bend deformation due to its material and thickness in high temperature conditions. 3A illustrates a state in which the tray 7 is bent downward by gravity by turning the disc drive upside down, and FIG. 3B illustrates a state in which the tray 7 is bent downward by gravity when the disc drive is normally placed. It is shown.

When the bending deformation of the tray 7 occurs, the disk may not be properly seated on the upper surface of the tray 7, and thus, the noise and vibration of the disk drive may be increased when the disk is rotated. In addition, when the tray 7 is deflected, when the tray 7 is loaded or unloaded from the main base 1, the tray 7 may be caught or loaded under each part of the inlet of the disc drive or the main base 1. Will be created. Therefore, the development of a structure for solving various problems caused by the bending of the tray 7 is required by regulating the bending deformation of the slimmed tray 7 vulnerable to high temperature conditions.

 Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to provide a vibration and deformation preventing structure of a disk drive that regulates the deflection of a tray due to temperature rise.

Another object of the present invention is to provide a vibration and strain relief structure of a disc drive that restricts flow in the width direction as well as the height direction of the tray.

According to a feature of the present invention for achieving the object as described above, the present invention has a side wall formed at both ends in the front and rear direction and a rear side wall connecting the side wall, a plurality of guides on the inner surface of the side wall A main base provided with a boss, a guide channel supported on the main base and guided by the guide boss and entering and exiting in the front and rear directions of the main base, a height direction of the tray relative to the main base, And a guide member corresponding to each of the main base and the tray to regulate the bending deformation, wherein the guide member includes the main base such that a loaded tray enters therebetween to prevent heightwise flow and bending deformation. It is configured to include a tension portion protruding at a predetermined interval on the rear side wall.

The guide member may include the boss portion inserted between a boss portion protruding in a height direction on an upper surface of the main base and a cutout portion cut in a longitudinal direction at a rear end of the tray to prevent the flow in the width direction of the tray. It further comprises a rib formed to protrude elastically along the longitudinal direction of the cutout.

The tension part may be configured to include an upper hook corresponding to an upper surface of the tray and a lower hook corresponding to a lower surface of the tray to face each other.

At least one tension portion is formed along the width direction of the tray.

The tension portion is provided at approximately 1/3 and 2/3 points along the width direction of the tray, respectively.

At the tip of the tension portion, a curved surface or a chamfered guide inclined surface is formed so that the tray is not caught by the tension portion when the tray enters the tray.

According to the present invention having such a configuration, the bending deformation that may be generated in the tray at the time of temperature rise according to the slimming of the tray is regulated by the tension unit, thereby reducing the degree of deformation thereof.

Hereinafter, a preferred embodiment of the vibration and deformation preventing structure of the disk drive according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 4 is a plan view showing a disk drive employing a preferred embodiment of the vibration and deformation prevention structure of the disk drive according to the present invention, Figure 5 is a perspective view showing the main configuration of the embodiment of the present invention, Figure 6 is It is sectional drawing along the AA line. 7 is a cross-sectional view showing the relationship between the tray and the tension portion in the embodiment of the present invention.

As shown in these figures, the main base 20 serves as a skeleton of the disk drive, and sidewalls 21 having a predetermined height are formed at both ends thereof. The side wall 21 extends along both ends from the front end to the rear end of the main base 20. In addition, a rear side wall 23 connecting the side walls 21 is formed at the rear end of the main base 20.

In addition, on the bottom surface of the main base 20, a driving unit (not shown) including a loading motor that provides a driving force for entering and exiting the tray 28 into and out of the drive is provided. This drive unit is composed of a plurality of gears and belts, the driving force is finally transmitted to the loading gear (24).

Guide bosses 25 are formed on both upper surfaces of the main base 20 corresponding to the inside of the side wall 21 to protrude a predetermined height upward. The guide boss 25 is formed in a number of places intermittently from the front end to the rear end of the main base 20. The length of each guide boss 25 is appropriately determined according to the design conditions.

A plurality of height regulating ribs 26 are formed on the inner surface of the side wall 21 to guide the heights of the upper surfaces of both ends of the tray 28 to be described below. The height regulating rib 26 is formed in a plurality in the direction facing each other on the side wall (21).

The tray 28 is installed on the upper surface of the main base 20. The tray 28 moves along the upper surface of the main base 20 to load and unload disks. To this end, a rack gear 29 engaged with the loading gear 24 is provided at one side of the lower surface of the tray 28 in the longitudinal direction of the tray 28. Guide channels (not shown) are formed at both ends of the lower surface of the tray 28. The guide boss 25 is inserted into the guide channel.

The disk seating surface 30 on which the disk is seated is formed on the upper surface of the tray 28. The door mounting opening 31 is provided at the front end of the tray 28. The door 33 is attached to the door mounting opening 31. The door 33 serves to open and close the entrance formed in the front panel of the set.

The inner peripheral surface of the rear wall 23 and the upper surface of the main base 20 adjacent to the rear wall 23 and the tray 28 prevent the flow and deformation of the tray 28 to prevent noise and vibration caused by the rotation of the disk. Guide member 40 is provided to minimize the. The guide member 40 includes a boss portion 41, a rib 43, and a tension portion 49.

The boss portion 41 protrudes from an upper surface of the main base 20 and is fitted to the rib 43 formed at the cutout portion 45 of the tray 28. Therefore, since the tray 28 is elastically coupled to the main base 20 by the boss portion 41, the vibration in the width direction of the tray 28 is minimized.

In other words, the rear end of the tray 28 is formed with a cutout portion 45 cut in the longitudinal direction. In addition, the cutout portion 45 is elastic to a substantially center portion of the cutout portion 45 so as to correspond to the thickness of the boss portion 41 so that the boss portion 41 of the main base 20 can be detachably fitted. A deformable rib 43 is configured. At this time, the rib 43 is close to the diameter of the boss portion 41 with the cut portion 45 so that the boss portion 41 receives only a minimum load when the boss portion 41 is separated from the cut portion 45. It is preferable that it is formed to have a spacing.

As such, the tray 28 is configured such that the boss portion 41 can be fitted into the rib 43 formed in the cutout 45 during loading, so that the disk has a load or a shock is applied to the disk drive. Vibration in the width direction is regulated.

On the other hand, the tension section 49 is composed of a pair of the upper hook 49a and the lower hook 49b substantially face, the upper hook 49a and the lower hook 49b is shown in FIG. As described above, the rear wall 23 protrudes to correspond to the top and bottom surfaces of the tray 28, respectively. At this time, the height direction interval between the upper hook 49a and the lower hook 49b is larger than the thickness of the tray 28 by a predetermined interval. Therefore, between the tray 28 and the upper hook 49a and the tray 28 and the lower hook 49b while the tray 28 is inserted between the upper hook 49a and the lower hook 49b. ), There is a predetermined gap. This is to allow the tray 28 to freely move in and out without load when the tray 28 is inserted between the upper hook 49a and the lower hook 49b.

However, it is preferable that any one of the upper hook 49a or the lower hook 49b is disposed closer to the tray 28 to regulate the bending deformation of the tray 28. In this case, since the deformation and flow of the tray 28 will be relatively limited through the hooks disposed closer to the tray 28, it is determined that the hook 28 is disposed close to the tray 28. It is preferable to determine the degree of flow. In the present embodiment, the gap between the tray 28 (about 0.1 to 0.3 mm) is smaller than the gap between the lower hook 49b and the tray 28 (about 0.8 to 1.2 mm). What was arrange | positioned to have was illustrated. This gap is such that the tray 28 is in contact with the upper hook 49a due to slight deformation or flow in the height direction of the tray 28. The upper hook 49a is elastically deformed to some extent and the Prevents deformation or flow of the tray 28.

The upper hook 49a and the lower hook 49b are not overlapped with each other on a plane, but are formed at a predetermined interval. This is to support the tray 28 while being properly elastically deformed with each other according to the bending of the tray 28. However, the upper hook 49a and the lower hook 49b are sufficient to be disposed to face the top and bottom surfaces of the tray 28, respectively, and need not be limited to the above arrangement.

In addition, the inlet portions of the upper hook 49a and the lower hook 49b into which the tray 28 is inserted, as shown in FIG. 7, are curved or chamfered guide inclined surfaces 49a 'and 49b'. Are each formed so that the tray 28 enters therebetween without being caught by the upper hook 49a or the lower hook 49b. This is guided through the guide inclined surfaces 49a 'and 49b' even if the tray 28 is deformed due to a change in temperature or the like, so that the gap between the upper hook 49a or the lower hook 49b disappears. This is to allow insertion of the tray 28 between the upper hook 49a and the lower hook 49b. In the present embodiment, the guide sloping surfaces 49a 'and 49b' are chamfered, respectively.

The tension unit 49 may be provided in at least one along the width direction of the tray 28. However, the tension unit 49 is preferably provided at about 1/3 and 2/3 points along the width direction of the tray 28 at the rear end of the tray 28 as in the present embodiment. This is because it is difficult to restrict the deformation of the central portion in the width direction if the tension portion 49 is disposed at all of the widthwise edges of the tray 28. This is because the tension part 49 may be bent due to the load or be broken due to the impact. Therefore, one or more tension units 49 may be provided along the width direction of the tray 28. If two tension units 49 are provided, it is preferable that the tension units 49 are disposed at points 1/3 and 2/3 in the width direction as described above. .

Reference numeral 50 denotes a clamp bracket at both ends of which is mounted on the upper ends of both sidewalls 21 of the main base 20, and 52 denotes a clamp that is installed at the clamp bracket 50 to fix the disk seated on the turntable.

Hereinafter, the configuration of the second embodiment of the vibration and deformation preventing structure of the disk drive according to the present invention will be described.

Figure 8 is a perspective view showing the configuration of the second embodiment of the vibration and deformation preventing structure of the disk drive according to the present invention from one side, Figure 9 is a perspective view showing the configuration of the combined state of the second embodiment according to the present invention from the other side .

As shown in these figures, in the present embodiment it can be seen that the structure of the guide member 130 is different from that of the first embodiment. In more detail, the guide member 130 of the present embodiment is largely composed of the boss 131, the rib 133, the tension 137 and the protrusion 139. Since the ribs 133 formed on the boss portion 131 and the cutout portion 135 are the same as those of the first embodiment, detailed description thereof will be omitted.

The tension part 137 is divided into an upper hook 137a and a lower hook 137b, and each of the tension parts 137 protrudes from the tray through hole 113 formed through the rear wall 111 of the main base 110. Here, at least one tray through-hole 113 is formed along the width direction of the tray 120 on the rear side wall (111). At this time, the position of the tray passage opening 113 is formed at 1/3 points and 2/3 points along the width direction of the tray 120. The protrusion 139 formed in the tray 120 is inserted into the tray through hole 113.

The upper hook 137a and the lower hook 137b are protruded from the upper and lower ends of the tray passage 113, respectively, and are bent at predetermined points. This is due to the flow and deflection of the tray 120 that each hook 137a, 137b is larger than that of the first embodiment when the protrusion 139 is in contact with the upper hook 137a and the lower hook 137b. To elastically deform and to regulate the movement of the protrusion 139.

The protrusion 139 protrudes from the rear end of the tray 120, and its position and width are formed in a position and width insertable into the tray passage hole 113. Since the protrusion 139 is restricted from movement and deformation of the tray 120 with respect to the flow and deformation of the tray 120, the protrusion 139 serves to prevent the flow and deformation of the tray 120.

Hereinafter, the configuration of the third embodiment of the vibration and deformation preventing structure of the disk drive according to the present invention will be described.

10 is a perspective view showing a configuration of a third embodiment of the vibration and deformation preventing structure of the disk drive according to the present invention.

As shown here, the guide member 230 in the present embodiment is composed of a boss portion 231, ribs 233, the tension portion 237 and the protrusion 239. Since the ribs 233 formed on the boss portion 231 and the cutout portion 235 are the same as those of the first embodiment, detailed description thereof will be omitted.

In the present embodiment, the tension part 237 protrudes from the through hole 213 penetrated through the rear wall 211 of the main base 210. That is, as shown in FIG. 10, protruding from the through hole 213 formed in the rear wall 211 to correspond to approximately 1/3 and 2/3 points along the width direction of the tray 220, 'b' It is formed to be bent into a shape.

Protrusions 239 formed at the rear end of the tray 220 are disposed on the top and bottom surfaces of the tension part 237, respectively. In other words, the protrusions 239 are divided into an upper protrusion 239a and a lower protrusion 239b, wherein each of the protrusions 239a and 239b is separated at a specific point of the rear end of the tray 220 to be spaced apart from each other. Extending in parallel. In this case, the height gap between the upper and lower protrusions 239a and 239b is designed to be similar to the height gap between the upper hook 49a and the lower hook 49b in the first embodiment. This is to prevent the height direction flow of each of the protrusions 239a and 239b and the bending deformation of the tray 220 by the tension portion 237 inserted into the upper and lower protrusions 239a and 239b.

Hereinafter, the operation of the vibration and deformation preventing structure of the disk drive according to the present invention having the configuration as described above will be described in detail. Here, since the operation of the second and third embodiments is substantially similar to that of the first embodiment, only the operation according to the first embodiment will be described below.

The tray 28 is guided by guide bosses 25 inserted into the guide channels in both sidewalls 21 of the main base 20 to perform a linear movement. The tray 28 moves between the front end and the rear end along the upper surface of the main base 20. At this time, the tray 28 is moved to the seated state on the disk seating surface 32 to load and unload the disk.

When the tray 28 moves along the upper surface of the main base 20 in this manner, the height of the tray 28 is regulated by the height regulating ribs 26. At this time, a predetermined gap is formed between the upper surface of the tray 28 and the height regulating rib 26, so that the tray 28 is smoothly moved.

Meanwhile, a predetermined gap is formed between the guide boss 25 and the guide channel and between the height regulating rib 26 and the upper surface of the tray 28. Thus, the gap between them allows the tray 28 to flow to some extent with respect to the main base 20. For reference, the gap may be maintained to some extent so that the tray 28 may be smoothly moved.

 When the tray 28 is supported by the main base 20 and loaded into the main base 20, the rear end of the tray 28 is restricted by the guide member 40. That is, the boss portion 41 of the guide member 40 is inserted into the rib 43 formed in the cutout portion 45 of the tray 28, and the trailing edge of the tray 28 is formed of the guide member 40. It is inserted into the tension part 49.

At this time, since the rib 43 can be elastically deformed to a certain extent in the width direction, the boss portion 41 is inserted as if the rib 43 is sandwiched. The guide slopes 49a 'and 49b' formed at the inlet portion of the tension portion 49 are chamfered to guide the tray 28 so that the tray 28 enters between the tension portions 49. As shown in FIG. .

As such, when the tray 28 completely enters the main base 20, the clamp 52 installed in the clamp bracket 50 fixes the disk. The turntable inserted through the hole in the center of the disk is rotated by the spindle motor, and the optical pickup device moves in the radial direction of the disk to read the signal of the disk.

In this case, the disc may have a bias load in the manufacturing process, which causes the tray 28 to flow when the disc rotates at a high speed. In addition, even if the disk drive is transported or impacted, the tray 28 on which the disk is seated can flow. If the tray 28 is moved during play of the disc, the optical pickup device will not be able to accurately read or record signals from the disc. Therefore, the guide member 40 provided in the main base 20 supports the tray 28 without shaking in order to prevent the flow in the width direction and the height direction of the tray 28.

 In other words, the boss 41 of the guide member 40 is fitted to the rib 43 formed in the cutout 45 at the rear end of the tray 28. At this time, the rib 43 is elastically deformed and movable in the width direction in the cutout 45 so that the tray 28 is properly deformed when the tray 28 is flowed in the width direction and minimizes the flow of the tray 28.

And the tension portion 49 of the guide member 40 is disposed at regular intervals on the upper and lower surfaces of the tray 28 to prevent the flow in the height direction of the tray 28, respectively. In this embodiment, the upper hook 49a is disposed closer to the tray 28 than the lower hook 49b. One or more of the tension parts 49 are formed along the rear end of the tray 28 to regulate the flow in the height direction of the tray 28. At this time, since the tension unit 49 is made of a plastic-based material, it has elasticity to some extent due to the material. Therefore, when the tray 28 flows in the height direction due to an impact or the like, the tension part 49 has a predetermined elastic deformation and minimizes the flow of the tray 28.

In addition, the tension unit 49 is formed adjacent to the upper and lower surfaces of the tray 28 and the tension unit 49 is disposed at approximately 1/3 and 2/3 points along the width direction of the tray 28. do. Accordingly, as the tray 28 is slimmer, the tray 28 may be bent relatively easily due to a high temperature, and the tension part 49 prevents warpage deformation.

In other words, if the temperature of the tray 28 rises, the tray 28 will bend upward or downward depending on the direction in which gravity is applied. However, two tension portions 49 are disposed in the width direction of the tray 28 to prevent bending of the tray 28. At this time, the tension unit 49 serves to prevent the tray 28 from being deformed any more while elastically deforming the bending of the tray 28. Therefore, the tray 28 can be used relatively stably even at high temperature conditions by overcoming the vulnerability to high temperature due to slimming.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self-evident.

Vibration and deformation prevention structure of the disk drive according to the present invention as described in detail above, the main base is provided with at least one tension portion corresponding to the upper and lower surfaces of the tray along the width direction of the tray. Therefore, according to the present invention, as the tray is slimmed, the bending deformation that may occur in the tray at the time of temperature rise is regulated by the tension part, thereby reducing the degree of deformation.

The tension part also faces the upper and lower surfaces of the tray with a predetermined gap so as to regulate the height vibration of the tray. In addition, in the present invention, in addition to the tension portion, the boss portion is provided in the main base to regulate the vibration in the width direction of the tray. Therefore, according to the present invention, there is an advantage of minimizing the generation of noise and vibration of the entire player by regulating the flow of the tray according to the high-speed rotation of the unloading disk in the height direction and the width direction.
