Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by referring to the accompanying drawings and examples.

FIG. 1 illustrates a schematic diagram of a hard disk cartridge according to some embodiments of the present application. FIG. 2 illustrates an exploded view of a hard disk cartridge according to some embodiments of the present application. FIG. 3 illustrates a partial structural schematic of a hard disk cartridge according to some embodiments of the present application. Figure 4 shows a schematic cross-sectional view of the structure of figure 3. Fig. 5 shows a partial enlarged view of the structure in fig. 4. FIG. 6 illustrates a schematic view of a spring according to some embodiments of the present application. Fig. 7 shows a schematic cross-sectional view of the spring of fig. 6.

As shown in fig. 1 to 7, the hard disk cartridge may include: a bracket 1 accommodating a hard disk 2, a first case 3, and at least one elastic member 4. For example, 4 elastic members are shown in fig. 2, but not limited thereto.

The elastic member 4 is fixed between the first housing 3 and the bracket 1. The elastic member 4 is made of an elastic material such as rubber. The elastic member 4 has a closed inner cavity 41. In other words, the elastic member 4 has a hollow structure.

When the hard disk cartridge is in a shock condition, the force generated by the shock is transmitted to the elastic member 4. The elastic member 4 is elastically deformed by the force. In the elastic deformation process, the damping force generated by the elastic part 4 can offset the force generated by vibration, and the force generated by vibration can be prevented from acting on the hard disk 2, so that the hard disk 2 is buffered and the shock absorption and protection performance of the hard disk cartridge on the hard disk 2 is improved. In addition, when the hard disk cartridge vibrates, damping force to the vibration is generated through air pressure change when the closed inner cavity 41 in the elastic part 4 of the hard disk cartridge is zoomed, and the hard disk cartridge further has a buffering effect on the hard disk 2. For example, during the elastic deformation of the elastic member 4, the closed cavity 41 is during the zooming process (i.e. the process of compressing and restoring the volume to the uncompressed state, or the process of expanding and restoring the volume to the uncompressed state), the air pressure in the closed cavity 41 changes due to the compression and dilution of the air in the closed cavity, and a pressure difference is generated inside and outside the elastic member 4, and the pressure generated by the pressure difference can further counteract the force generated by the external vibration, thereby damping the hard disk 2.

In summary, the hard disk cartridge according to the embodiment of the present application can provide buffering protection for the hard disk 2 through the elastic member 4.

In some embodiments, as shown in fig. 5 to 7, the elastic member 4 includes a drum structure 42 and a flange 43. The drum 42 has a closed inner cavity 41. The closed cavity 41 is, for example, drum-shaped. A flange 43 extends from the outer periphery of the drum 42. In other words, the flange 43 extends radially from the shell of the drum-like structure 42. The flange 43 is provided with an annular weakening groove 44. For example, the flange 43 may include two weakening grooves 44 that are mirror symmetric. The weakening groove 44 makes the flange 43 thinner near the drum than the outer edge of the flange 43. Here, when the elastic member 4 is largely deformed, the flange 43 may function to improve the ability of the elastic member 4 to return from the deformed state to the original state, thereby improving the shock absorbing ability of the elastic member 4. When the elastic element 4 deforms less, the position of the flange 43 close to the drum body is made thinner, and the weakening groove 44 can facilitate elastic deformation of the drum-shaped structure 42, so that shock absorption of the drum-shaped structure 42 is facilitated.

In some embodiments, as shown in fig. 5 to 7, the first end of the elastic member 4 has a first blind hole 45. The second end of the resilient member 4 has a second blind bore 46. The hard disk cartridge further includes a first spacer 51, a first blind rivet 61, a second spacer 52, and a second blind rivet 62.

The first spacer 51 is embedded in the elastic member 4 and is located at a first end of the elastic member 4. The first blind rivet 61 rivets the first washer 51 to the carrier 1 via the first blind hole 45. In this way, the hard disk cartridge can rivet and fix the elastic member 4 and the bracket 1 through the first blind hole 45, the first spacer 51 and the first blind rivet 61.

A second spacer 52 is embedded in the resilient member 4 at a second end of the resilient member 4. The second blind rivet 62 rivets the second washer 52 to the first housing 3 through the second blind hole 46. In this way, the hard disk cartridge can rivet and fix the elastic member 4 and the first housing 3 through the second blind hole 46, the second spacer 52 and the second blind rivet 62. The connection method of the elastic member 4 to the first housing 3 and the bracket 1 is not limited to caulking, and other suitable fixing methods may be used.

In some embodiments, both the first gasket 51 and the second gasket 52 are vulcanized into the elastomeric member 4. In this way, the hard disk cartridge of the present application can embed the first gasket 51 and the second gasket 52 in the elastic member 4 by means of vulcanization. In other words, the embodiment of the present application may fix the first gasket 51, the second gasket 52, and the elastic member 4 as a single body by vulcanization. In addition, the first and second spacers 51 and 52 each have small holes for reinforcing the connection with the elastic member 4. For example, fig. 8 shows the apertures 53 and 54 of the first gasket 51. The elastic member 4 is made of rubber, for example. The rubber material of the elastic member 4 enters the small holes 53 and 54, thereby enhancing the coupling strength of the first gasket 51 and the elastic member 4.

The inner periphery of the first washer 51 has a tapered surface that engages with the first blind rivet 61. For example, fig. 8 shows the tapered surface 55 of the first washer 51. The first end of the first blind rivet 61 may be expanded to abut against the tapered surface 55 of the first washer 51. In addition, the carrier 1 has a conical bore for fixing the second end of the first blind rivet 61. Similarly, the inner periphery of the second washer 52 has a tapered surface that mates with the second blind rivet 62. The tapered surface of the second washer 52 may secure a first end of the second blind rivet 62. The first housing 3 has a tapered bore for fixing the second end of the second blind rivet 62.

In some embodiments, the hard disk cartridge may further include a second case 7, a third case 8, and a fourth case 9. The third housing 8 is snap fitted at the first end of the first housing 3. The fourth housing 9 is snap fitted at the second end of the first housing 3. The first housing 3 is fixed to the third housing 8 and the fourth housing 9 by means of snap fasteners. The first end of the second shell 7 is fixed with the third shell 8 through a buckle, and the second end of the second shell 7 is fixed with the fourth shell 9 through a buckle.

FIG. 10 illustrates a schematic view of mounting a fourth housing according to some embodiments of the present application. FIG. 11 illustrates a schematic view of mounting a second housing according to some embodiments of the present application.

As shown in fig. 9, the third housing 8 includes snap holes 81, 82, 83, 84, 85, and 86. The first housing 3 includes projections 31, 32, 33, and 34 projecting toward the inside of the first housing 3. Here, the catching holes 81, 82, 83, 84 are snap-coupled with the protrusions 31, 32, 33, and 34, respectively.

As shown in fig. 10, the fourth housing 9 includes snap holes 91, 92, 93, and 94. The first housing 3 further includes projections 35, 36, 37 and 38. The snap holes 91, 92, 93 and 94 are snap-fit connected with the protrusions 35, 36, 37 and 38, respectively.

In some embodiments, as shown in fig. 11, the fourth housing 9 may further include snap holes 95, 96, 97, and 98. The first end of the second housing 7 includes projections 71 and 72 projecting toward the inside of the second housing 7. The second end of the second housing 7 comprises projections 73, 74, 75 and 76 projecting towards the inside of the second housing 7. The first end of the second housing 7 is snap-coupled with the snap holes 85 and 86 of the third housing 8 through the protrusions 71 and 72. The second end of the second housing 7 is snap-fitted with snap holes 95, 96, 97 and 98 of the fourth housing through the projections 73, 74, 75 and 76. In addition, the hard disk cartridge of the present application may further fix the first case 3 and the second case 7 by screws. Here, the closed cavity formed by the first housing 3, the second housing 7, the third housing 8 and the fourth housing 9 accommodates the bracket 1. In addition, the third housing 8 may further include a Universal Serial Bus (USB) interface 87 and a vehicle video recorder (MDVR) interface 88, but is not limited thereto. The vehicle mounted video recorder (MDVR) interface is, for example, an interface such as SATA.

To sum up, according to the hard disk cartridge of this application embodiment can form closed cavity through the combination of casing, can the effectual air that completely cuts off in the external environment gets into the surface of hard disk 2 to reduce the 2 surface sensitive electron devices of hard disk and corroded by the sulphide in the outside air, and then reduce the hard disk fault rate. In addition, in the hard disk cartridge of the present application, the first to fourth shells may be made of a material convenient for heat dissipation, such as metal.
