However, in this case,
It is intended to suppress internal vibrations, and has a problem of weak absorption of vibrations such as external shocks.

Japanese Patent Laid-Open Publication No. Hei 7-106775 describes a method of mounting an HDD. This is because, as shown in FIGS. 6A and 6B, in an HDD mounting method for mounting an HDD (hard disk drive) in a control device unit such as a numerical control device, a part of the inside of the control device unit is used. A fixture 283 for attaching the HDD 281 to the
Anti-vibration rubber 284 for attaching D281 and HDD
And a weight member 182 attached to the main body case. However, in this case, there is a problem that the holding state of the vibration isolating rubber 284 to the fixture 283 is unstable, and it is not possible to cope with external vibration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a component holding structure in a housing according to the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view showing a first embodiment of a component holding structure in a housing according to the present invention, and FIG. 2 is an exploded perspective view thereof.

As shown in FIG. 1 and FIG. 2, the component holding structure in the housing of the first embodiment includes a left and right portion of a bottom surface 21a of a main body 21 of a housing 2 for storing a component 1 comprising a hard disk for a personal computer. In the vicinity of the side walls, leaf springs 3, 3 whose center is bulged upward in the longitudinal direction are screwed and arranged. Further, the lid 22
In the lower surface 22a of the lower surface 22a, leaf springs 3, 3 whose central portions are swelled downward in the longitudinal direction are arranged with screws at both ends thereof in the vicinity of both left and right edges.

As shown in FIG. 1, after the component 1 made of a hard disk for a personal computer is put in the main body 21 of the housing 2 and the lid 22 is closed, the bottom surface 21 a of the main body 21 is closed. The leaf spring 3 arranged,
The component 2 is pressed from above and below by the leaf springs 3 and 3 disposed on the lower surface 22a of the lid 22 to be elastically held.

Therefore, even if vibration such as impact is generated from the outside to the housing 2, the vibration is absorbed by the plurality of leaf springs 3, and a component comprising a hard disk for a personal computer elastically held by the leaf springs 3. Since this vibration is not transmitted to the component 1, the component 1 composed of a hard disk for a personal computer is generated by a vibration such as an external impact.
Can be prevented from being damaged. Moreover, the lid 22
By simply opening, the component 1 composed of the hard disk for the personal computer stored in the main body 21 of the housing 2 can be easily taken out.

FIG. 3 is a perspective view showing a part of the component holding structure in the housing of the second embodiment. As shown in FIG. 3, the component holding structure in the housing according to the second embodiment includes front and rear side walls on the bottom surface 21a of the main body 21 of the housing 2 for housing the component 1 (see FIG. 1) formed of a hard disk for a personal computer. The leaf springs 3, 3, 3 whose center is bulged upward in the direction perpendicular to the longitudinal direction are screwed and arranged in the vicinity of and in the substantially central portion in the longitudinal direction. Although not shown, a leaf spring whose center is bulged downward in a direction perpendicular to the longitudinal direction is attached to the front and rear edges and a substantially central portion in the longitudinal direction of the lower surface 22a (see FIG. 2) of the lid portion 22. It is good to arrange the part with screws.

In the component holding structure in the housing of the second embodiment, after the component 1 (see FIG. 1) made of a hard disk for a personal computer is put in the main body 21 of the housing 2, a lid (not shown) is used. To close the main unit 2
The leaf springs 3, 3, and 3 disposed on the bottom surface 21a of the first unit and a plurality of leaf springs disposed on the lower surface of a lid (not shown) are used.
The component 2 is pressed from above and below to be elastically held. Therefore, even if vibration such as impact is generated in the housing 2 from the outside, the vibration is absorbed by the plurality of leaf springs 3 and the component 1 made of a hard disk for a personal computer elastically held by these leaf springs 3 (see FIG. 1), it is possible to prevent the component 1 composed of a hard disk for a personal computer from being damaged by vibration such as an external impact. Moreover, by simply opening the lid (not shown), the component 1 (see FIG. 1) composed of the hard disk for the personal computer stored in the main body 21 of the housing 2 can be easily taken out.

FIG. 4 is a longitudinal sectional view showing a component holding structure in a housing according to a third embodiment. As shown in FIG. 4, the component holding structure in the housing according to the third embodiment is configured such that a plurality of springs 4 are provided on a bottom surface 21a of a main body 21 of a housing 2 for housing a component 1 formed of a hard disk for a personal computer. Have been placed. Further, on the lower surface 22a of the lid 22,
A plurality of springs 4 are arranged downward. And
As shown in FIG. 4, when the lid 22 is closed after the component 1 made of the hard disk for a personal computer is put in the main body 21 of the housing 2, a plurality of parts arranged on the bottom surface 21 a of the main body 21 are opened. By the spring 4 and the plurality of springs 4 arranged on the lower surface 22a of the lid 22,
The component 2 is pressed from above and below to be elastically held.

Therefore, even if vibration such as impact is generated in the housing 2 from the outside, the vibration is absorbed by the plurality of springs 4 and the component 1 composed of a personal computer elastically held by the springs 4 has this vibration. Since the vibration is not transmitted, it is possible to prevent the component 1 composed of the hard disk for the personal computer from being damaged by vibration such as an external impact. Moreover, by simply opening the lid 22, the component 1 composed of the hard disk for the personal computer stored in the main body 21 of the housing 2 can be easily taken out.

As described above, according to the first aspect of the present invention, the bottom of the main body of the housing and the lower surface of the lid are provided on the bottom of the housing.
By pressing against the lower and upper surfaces of the components housed in this housing,
Since a plurality of elastic bodies for holding the parts are arranged, the plurality of elastic bodies can absorb vibrations such as an external shock or the like, and the parts held in the housing can be protected from external shocks or the like. Physical damage due to vibration can be prevented, and components can be taken out from the main body of the housing by opening the lid, and components can be easily attached to and detached from the housing.

According to the second aspect of the present invention, since the elastic body is a leaf spring, the entire structure can be simplified and provided at a low cost. According to the third aspect of the present invention, since a plurality of leaf springs are arranged in the longitudinal direction on the bottom of the main body of the housing and the lower surface of the lid,
Vibration such as shock from the outside of the housing can be flexibly absorbed by these leaf springs, and damage to components in the housing can be reliably prevented.

According to the fourth aspect of the present invention, a plurality of leaf springs are arranged on the bottom of the main body of the housing and the lower surface of the lid in a direction orthogonal to the longitudinal direction. Many can be arranged as necessary, and vibration such as impact from the outside of the housing can be reliably absorbed by these leaf springs, and damage to components in the housing can be more reliably prevented. . According to the fifth aspect of the present invention, since the elastic body is a spring, it can be manufactured at a low cost. Even if vibration such as impact is partially transmitted to the housing from the outside, the vibration is partially reduced. It is possible to prevent the partial damage of the components in the housing.

According to the invention described in claim 6, the component is
Since it is a hard disk for a personal computer, the elastic body can absorb vibrations such as shocks from the outside of the housing and prevent damage to the hard disk for the personal computer. Condition can be maintained.
