And a cushioning gasket provided. The cover-side storage case and the bottom-side storage case are joined in contact with each other. In this state, the stored magnetic disk device is supported by both gaskets.
Japanese Patent Application Laid-Open No. 2002-163885

By the way, in electronic devices such as DVD drives with built-in devices that generate vibrations such as disk drives, the high-end model and the low-priced model share a chassis, and multiple models can be configured with or without vibration absorbing cushioning materials. It is possible to do. In such a case, in the configuration of the drive unit storage case of the conventional magnetic disk device described above, if the storage case is shared with or without a gasket, the magnetic disk device cannot be properly supported in the low-cost model.
However, using a common housing and simply dividing the model according to the presence or absence of cushioning material, if a thick cushioning material with sufficient cushioning performance is provided, the supporting side lid panel is supported. It is assumed that the main body panel is lifted and screw holes for attaching the lid panel to the main body panel are not aligned. On the other hand, it is assumed that a sufficient cushioning performance cannot be obtained if a thin cushioning material with a degree of screw hole matching is provided.

  The present invention provides a housing for an electronic device that can be used in common without any problem in the case where a cushioning material is provided and a case in which the cushioning material is not provided, and an electronic device including the casing of the electronic device in which the thickness of the cushioning material is not limited The issue is to provide.

  The housing of the electronic device according to the present invention includes a first panel, a second panel having a second panel body orthogonal to the first panel, a second panel having a panel receiving piece extending from one end of the second panel body, and receiving the first panel; A flat part parallel to the first panel for installing a cushioning material provided between the second panel and the first panel provided on the receiving piece, and provided on the panel receiving piece when there is no cushioning material And a protrusion directly receiving the first panel.

  According to this configuration, when the cushioning material is interposed between the first panel and the second panel, the cushioning material is installed on the flat portion of the panel receiving piece formed on the second panel, and the cushioning material is used to Support one panel directly. Further, when the cushioning material is not provided between the first panel and the second panel, the first panel is directly supported by the projection of the panel receiving piece formed on the second panel. In this case, even if the cushioning material has a sufficient thickness, the height position of the first panel is extremely different depending on the presence or absence of the cushioning material, as long as there is no extreme difference between the height of the cushioning material and the height of the protrusion. There is no trouble in assembling (attaching) the first panel to the second panel. In other words, the first panel and the second panel can be used in common with and without the cushioning material provided that the cushioning material is not provided, and the cushioning material is not limited in thickness and is sufficient for the provided cushioning material. Can exhibit excellent vibration absorption performance. The protrusion may be formed by bending the panel receiving piece, or may be formed by cutting or raising. Further, the protrusion may be a separate member. Furthermore, the number and position of the protrusions are arbitrary.

  In this case, the first panel has a first panel main body and a falling piece extending so as to overlap with the second panel main body from the end of the first panel main body, and the first panel is fixed to the second panel at the overlapping portion. Mounting screws, fastening holes for mounting screws formed in the overlapped portion of the second panel body, and through holes for mounting screws formed in the falling pieces, and cushioning material installed on the flat part In this state, it is preferable that the fastening hole is configured to be visible through the through hole.

  According to this configuration, there is no problem in the screwing operation of the first panel with respect to the second panel depending on whether or not the cushioning material is provided. In addition, when a shock absorbing material is installed in the flat part, it is preferable to lightly press the first panel and align the through hole with the fastening hole, and then screw the mounting screw.

  Further, it is preferable that the flat portion is formed by bending the end portion of the second panel, and the protruding portion is formed by cutting and raising the end portion of the second panel relative to the flat portion to be bent. .

  According to this configuration, when the second panel is manufactured, the protrusion can be easily formed by cutting out (punching) the protrusion and forming the flat portion by bending. In addition, since the protruding portion is formed in the vicinity of the bent portion and in parallel with the flat portion, the protruding portion can function as a positioning member when a cushioning material is provided on the flat portion.

  Similarly, it is preferable that the flat portion and the protruding portion are formed by bending the end portion of the second panel at a right angle and bending the bent piece into a cross-sectional crank shape.

  According to this structure, a flat part and a projection part can be formed simultaneously by bending the panel receiving piece in two steps. In this case, if the flat portion and the protruding portion are formed in parallel to each other, the protruding portion can function as a positioning member when a cushioning material is provided on the flat portion.

  Furthermore, it is preferable that the first panel is a bonnet and the second panel is a rear panel.

  According to this configuration, the rear panel and the bonnet can be used in common with and without the cushioning material provided with the cushioning material, and the cushioning material is not limited in thickness, and is sufficient for the provided cushioning material. It is possible to exhibit a simple vibration absorbing function.

  An electronic device according to the present invention includes the above-described electronic device casing and an internal device housed in the casing.

  According to this configuration, a part or all of the housing can be shared to appropriately configure the housing provided with the cushioning material and the housing not provided, without impairing the function as the housing, Overall, the cost can be reduced.

  Hereinafter, a case where a housing of an electronic device according to an embodiment of the present invention is applied to an AV device will be described with reference to the accompanying drawings. This AV equipment is equipped with a power device such as a disk drive, and a middle or high-end model and a low-priced model depending on the presence or absence of a shock absorber that absorbs vibrations from the power device. The two models are configured.

  As shown in the external perspective views of FIGS. 1 and 2, the AV device 1 is configured by incorporating an AV apparatus including a disk drive 3 in a housing 2, and the housing 2 is mounted on a base frame 4. A front panel 5, a rear panel (second panel) 6, and a bonnet (first panel) 7 are incorporated. The front panel 5 is supported by the base frame 4 via a panel stay 8 to which a switch, a lamp and the like are attached. The rear panel 6 is directly supported by the rear end portion of the base frame 4 at the lower part. Furthermore, the bonnet 7 is hooked to the front panel 5 at the front end, and is supported by the rear panel 6 and the base frame 4 so as to cover the inside of the apparatus from above. In addition, these panels which comprise the housing | casing 2 are formed, for example with the press molded product (made of sheet metal).

  The rear panel 6 is formed by folding the upper end portion and both right and left ends inward, and a panel receiving piece 13 for receiving the bonnet 7 is constituted by the upper end portion. That is, the rear panel 6 includes a rear panel main body 11 in a standing posture in which various through holes and vent holes are formed, and a pair of side end bent pieces 12 and 12 that extend at right angles from the left and right ends of the rear panel main body 11, The rear panel body 11 is integrally formed with a panel receiving piece 13 that extends at a right angle from the upper end of the rear panel body 11. The rear panel 6 is screwed to the base frame 4 at three locations at the lower end portion of the rear panel body 11 and at two left and right end portions.

  The bonnet 7 is bent in an inverted “U” shape as a whole, the front end portion being hooked to the front panel 5, and the rear end portion overlapping the rear panel (rear panel body 11) 6. However, each is bent. That is, the bonnet 7 includes a top panel portion 21 corresponding to the main body, a pair of left and right side panel portions 22, 22 connected to both sides of the top panel portion 21, and a plurality of projections provided at the front end of the top panel portion 21. A latch piece 23, a rising piece 24 extending perpendicularly downward from the rear end of the top panel 21 and a pair of left and right rear end bent pieces extending perpendicularly inward from the rear end of each side panel 22 25 and 25 and are integrally formed. The bonnet 7 is hooked to the front panel 5 by a plurality of hooking pieces 23, screwed to the base frame 4 at two locations of each side panel portion 22, and further rear panel ( The rear panel body 11) 6 is fastened to the base frame 4 with the screws fastened together.

  As described above, in the present embodiment, a part or all of the housing 2 is a common part, and the mid-high-end model and the low-cost model are configured by the presence or absence of the cushioning material 9. More specifically, the base frame 4, the rear panel 6, the bonnet 7, and the panel stay 8 except for the front panel 5 are used as common parts, and the base frame 4, the rear panel 6, the panel stay 7, and the bonnet 7 are interposed. Depending on the presence / absence of a plurality of cushioning materials 9 to be provided, a medium-high class model and a low-priced model are configured. The cushioning material 9 absorbs the vibration of the disk drive 3 that has propagated to the base frame 4, the rear panel 6, and the panel stay 8, shields the propagation of vibration to the bonnet 7, and prevents its resonance.

  In this case, each of the plurality of cushioning materials 9 is formed of a square piece, for example, a plurality (three in the figure) between the rear panel 6 and the bonnet 7 and a plurality between the panel stay 7 and the bonnet 7. A plurality (not shown) are interposed between the base frame 4 and the bonnet 7 (four in the figure), and are arranged at equal intervals. Therefore, the structure in which the housing 2 is shared depending on the presence or absence of the buffer material 9 will be described in detail below by taking the structure between the rear panel 6 and the hood 7 as an example.

  As shown in FIGS. 3 and 4, the panel receiving piece 13 of the rear panel 6 has protrusions 31 formed at a plurality of locations (two locations shown in FIG. 1). That is, the panel receiving piece 13 includes a plurality of protrusions 31 extending in the vertical direction from the rear panel main body 11 and a flat portion 32 extending in the horizontal direction from the rear panel main body 11. The plurality of protrusions 31 function as portions that directly receive the bonnet 7 when the cushioning material 9 is not provided, and the flat portion 32 adheres the plurality of cushioning materials 9 when the cushioning material 9 is provided (intermediate). It functions as a portion to be provided (see FIG. 4). As shown in FIG. 3B, the plurality of protrusions 31 and the flat part 32 are a plurality of reverse portions that become the protrusions 31 when punching (pressing) various through holes and the like in the rear panel 6. A “U” -shaped punching portion 31 a is formed, and a portion that becomes the flat portion 32 is bent at a right angle at both circular base portions of the punching portion 31 a. That is, the protrusion 31 is formed so as to cut and raise the punched portion 31 a relative to the flat portion 32.

  In addition, the number of the protrusion parts 31 is arbitrary as long as it is plural, and similarly, the number of the buffer materials 9 is also arbitrary. Moreover, if the buffer material 9 is stuck on the position of the protrusion 31, the buffer material 9 can be attached with high accuracy using the one-letter-shaped protrusion 31 as a reference for alignment. Furthermore, the number of the screwing points is also arbitrary.

  As shown in FIG. 4, the rear panel 6 and the bonnet 7 are screwed at a plurality of locations between the upper end portion of the rear panel main body 11 and the falling piece 24 of the bonnet 7 overlapping therewith. Specifically, a tapping screw (self-tapping screw) 41 is used as a screw (mounting screw) for fixing the screw, and a through-hole 42 serving as a so-called fool hole is formed in the rear panel body 11 so that the bonnet 7 is lowered. A fastening hole 43 serving as a so-called pilot hole is formed in the piece 24 by burring. For example, the tapping screw 41 has a nominal diameter of 3 mm, the through hole 42 has a diameter of 3.1 mm, and the fastening hole 43 has a diameter of 2.6 mm. Note that the through hole 42 is preferably a horizontally long hole in consideration of the assembly error of the entire housing 2 (however, one of the plurality of through holes 42 is a round hole for left and right positioning). (The diameter is 3.1 mm.) In such a case, 3.1 mm is the width of the through hole.

  On the other hand, when the cushioning material 9 is provided, the thickness of the cushioning material 9 or the height of the protruding portion 31 is considered so that the bonnet 7 does not contact the protruding portion 31. At the same time, it is necessary to share the through hole 42 and the fastening hole 43 regardless of the presence or absence of the cushioning material 9, so that the dimensional difference between the thickness of the cushioning material 9 and the height of the protruding portion 31 can It is necessary to make it within a range that does not cause trouble. The maximum vertical positional relationship between the through hole 42 and the fastening hole 43 that does not interfere (allow) the tapping screw 41 is driven is (3.1-2.6) /2=2.5 mm. Here, when this allowable value is set to 2.0 mm and the cushioning material 9 is provided, a gap of 2.0 mm is formed between the lower surface of the bonnet 7 and the upper end of the protruding portion 31.

  A commercially available product is used for the cushioning material 9 installed on the flat portion 32, for example, a 1.0 mm one. The free cushioning material 9 has a thickness of 1.0 mm, and the thickness of the interposed cushioning material 9 is designed to be 0.8 mm in consideration of the compression caused by the load of the bonnet 7 and the like. In consideration of 2.0 mm as the allowable value, the protruding portion 31 has a shape protruding 0.6 mm from the surface of the flat portion 32 (the height of the protruding portion 31). That is, in the design, when the cushioning material 9 is not provided, the above-described allowable value becomes zero, and the through hole 42 and the fastening hole 43 are positioned on the same axis, and screwing is performed (FIG. 4A). When the cushioning material 9 is provided, the allowable value is 2.0 mm, and screwing is performed in a state where the through hole 42 is displaced upward with respect to the fastening hole 43 (FIG. 4). (See (b)). The allowable value of 2.0 mm ensures that the rear panel 6 and the bonnet 7 do not come into direct contact when the cushioning material 9 is provided. Further, the allowable value of 2.0 mm appears as a difference in the installation height of the bonnet 7 between the case where the cushioning material 9 is not provided and the case where it is provided, but it does not affect the function and appearance design of the housing 2. .

  In the actual assembly of the bonnet 7 to the rear panel 6, when the cushioning material 9 is “none”, the bonnet 7 is placed so as to be supported by each protrusion 31, and the fastening hole 43 is visible through the through hole 42. The tapping screw 41 is screwed. Further, when the cushioning material 9 is “present”, the bonnet 7 is placed so as to be supported by each cushioning material 9, and the hood 7 is submerged so that the cushioning material 9 is somewhat compressed (set to 0.8 mm). In this state, the tapping screw 41 is screwed into the fastening hole 43 that is visible through the through hole 42. In addition, it cannot be overemphasized that the dimension of each part in said embodiment is suitably changed by the thickness etc. of the buffer material 9 to be used.

  Next, the housing 2 of the second embodiment will be described with reference to FIGS. In this embodiment, the panel receiving piece 13 of the rear panel 6 is formed by being bent in a cross-sectional crank shape. Specifically, a portion corresponding to the panel receiving piece 13 is bent at a right angle with respect to the rear panel 6 obtained by punching various through holes and the like, and the bent piece is further bent into a crank shape in cross section. That is, the panel receiving piece 13 of the rear panel 6 includes a horizontal protrusion (protrusion) 51 bent at a right angle from the rear panel main body 11 and a horizontal flat portion (flat part) connected to the horizontal protrusion 51 with a stepped portion. And 52 are integrally formed. The horizontal flat portion 52 is disposed at a slightly lower position with respect to the horizontal projection portion 51, and both extend to the full width in the left-right direction of the rear panel 6.

  Similarly to the first embodiment, the horizontal protrusion 51 functions as a portion that directly receives the bonnet 7 when the buffer material 9 is not provided, and the horizontal flat portion 52 includes a plurality of buffer materials when the buffer material 9 is provided. It functions as a part for attaching (interposing) the material 9 (see FIG. 6). When the dimensions of the respective parts are set in the same manner as in the first embodiment, in the design, when the cushioning material 9 is not provided, the above allowable value becomes zero, and the through hole 42 and the fastening hole 43 are coaxial. When the screwing is performed at the position (refer to FIG. 6A) and the cushioning material 9 is provided, the above-described allowable value is 2.0 mm, and the through hole 42 is higher than the fastening hole 43 by that amount. Screwing is performed with the position shifted to (see FIG. 6B).

  As described above, according to these embodiments, there is almost no difference in the height of the bonnet 7 between the case where the cushioning material 9 is interposed between the rear panel 6 and the bonnet 7 and the case where the cushioning material 9 is not interposed. In addition, since there is no hindrance to screwing, the main part of the housing 2 can be used in common for the mid-high-grade model and the low-cost model. In addition, when the cushioning material 9 is interposed, a sufficient installation space in the height direction of the cushioning material 9 can be taken, so that the thickness of the cushioning material 9 that affects the vibration absorption performance is not limited. .

  In addition, in a flat part and a projection part formed in a panel receiving piece, each shape, formation method, number, etc. are arbitrary. Moreover, you may make it comprise a protrusion part separately with respect to a flat part.
