DETAILED DESCRIPTION OF THE INVENTION

[0009] [Embodiment 1] A first embodiment of the present invention will be described below with reference to the drawings. The following describes an example in which the housing structure according to the present invention is applied to a housing 12 of a display device 1 for a television receiver. However, the present invention is not limited to this, and can also be applied to housings of display devices for computers, etc. It can also be applied to housings of other devices, such as various recorders such as DVD recorders and Blu-ray disc recorders, and sound bars.

[0010] In addition, in order to make the explanation clearer, the drawings may schematically show the width, thickness, shape, etc. of each part compared to the embodiment, and the width, thickness, shape, etc. of each part in the drawings do not limit the present invention.

[0011] <Outline of Display Device 1> 1 is a diagram showing an example of the appearance of a display device 1 according to a first embodiment of the present invention. The diagram indicated by reference numeral 100A is a perspective view of the display device 1, the diagram indicated by reference numeral 100B is a front view, and the diagram indicated by reference numeral 100C is a rear view.

[0012] Here, when viewing the display panel 11 from the front, the direction pointing left in the width direction of the display panel 11 is referred to as the X1 direction, and the direction opposite to the X1 direction is referred to as the X2 direction. The direction pointing upward in the height direction of the display panel 11 is referred to as the Y1 direction, and the direction opposite to the Y1 direction is referred to as the Y2 direction. Furthermore, the direction perpendicular to X1 and X2 and also perpendicular to Y1 and Y2, running from the back side to the front side of the display panel 11 is referred to as the Z1 direction, and the direction opposite to the Z1 direction is referred to as the Z2 direction. Note that when X1 and X2, Y1 and Y2, and Z1 and Z2 are referred to collectively without distinction, they will be referred to as the X direction, Y direction, and Z direction, respectively.

[0013] As shown in Figure 1, the display device 1 includes a display panel 11, a housing 12 including a rear cover (cover member) 2, etc., a chassis part 5 (see Figure 3) located inside the housing 12, and a stand 14 supporting the display panel 11, etc.

[0014] The display panel 11 is configured, for example, in a horizontally long rectangular shape, and displays images and various information, etc. The display panel 11 is realized by a liquid crystal display, an organic EL display, a plasma display, or the like.

[0015] The chassis section 5 (predetermined component) is disposed within an opening 121 of the housing 12, which will be described later, and is made of a metal such as aluminum or iron. The chassis section 5 is located on the rear side of the display panel 11, and is formed, for example, in a horizontally elongated rectangular shape similar to the display panel 11, and is a plate-like member extending across both ends of the opening 121 in the width direction (X direction). The chassis section 5 is not limited to this, and may be shorter than the length of the opening 121 in the width direction.

[0016] A display panel 11, a rear cover 2, and other electronic components are attached to the chassis section 5. The chassis section 5 also has an LED board (not shown) attached thereto and is provided with a heat dissipation function for the LED board.

[0017] The housing 12 includes a rear cover 2, various panels (not shown) such as a front panel, and an opening 121 (see 300A in FIG. 3).

[0018] The opening 121 is an opening in the housing 12, and is located on the rear side of the chassis 5, and is an opening on the rear side of the display device 1. Specifically, the opening 121 is an opening defined by the housing 12 other than the rear cover 2, for example, a top panel, a side panel, a bottom panel, etc. (not shown). The opening 121 is covered by the rear cover 2 when the display device 1 is in use.

[0019] The rear cover 2 is made of resin such as PC-ABS (polycarbonate ABS) or HIPS (high impact polystyrene). The rear cover 2 is located on the rear side of the opening 121, is disposed on the rear side of the display device 1 so as to cover the opening 121, and is detachably attached to the display panel 11 via the chassis part 5. The rear cover 2 is removed from the display panel 11, for example, when the display device 1 is inspected, repaired, or disassembled.

[0020] As will be described in detail later, the rear cover 2 is fixed to the display panel 11 by engagement between a first engagement portion 3 of the rear cover 2 and a second engagement portion 4 of the chassis portion 5. Furthermore, by rotating a second edge 27, which is an edge on the lower side (Y2 direction) of the rear cover 2, around a first edge 26, which is an edge on the upper side (Y1 direction) of the rear cover 2, as a rotation axis so as to move away from the opening 121, the engagement between the first engagement portion 3 and the second engagement portion 4 is released, and the rear cover 2 can be removed from the display panel 11. Furthermore, by removing the rear cover 2, the opening 121 is opened.

[0021] Furthermore, the resin rear cover 2 and the metal chassis 5 have different linear expansion coefficients, and therefore the amounts of contraction and expansion due to temperature changes are different. For this reason, for example, if the temperature of the environment in which the display device 1 is placed changes, the relative positions of the first engagement portion 3 of the rear cover 2 and the second engagement portion 4 of the chassis 5 may change, which could result in undesired disengagement between the first engagement portion 3 and the second engagement portion 4.

[0022] For this reason, in the display device 1 according to the present invention, the first fitting portion 6 is disposed near the first engagement portion 3 of the rear cover 2, and the second fitting portion 7 is disposed near the second engagement portion 4 of the chassis portion 5. By fitting the first fitting portion 6 and the second fitting portion 7 together, the relative positions of the first engagement portion 3 and the second engagement portion 4 change due to temperature changes, and this prevents the first engagement portion 3 and the second engagement portion 4 from becoming disengaged.

[0023] In this embodiment, the rear cover 2 rotates in the vertical direction, but may be rotated in the horizontal direction to open and close. In this case, for example, the end edge of the rear cover 2 in the X1 direction (the left side as viewed from the display panel 11 side) is used as a rotation axis to rotate the end edge of the rear cover 2 in the X2 direction (the right side as viewed from the display panel 11 side).

[0024] <Arrangement of engagement and fitting parts> (Arrangement of first engagement portion 3) 2 is a diagram showing an example of the rear cover 2 in a state where it is removed from the display panel 11. The diagram indicated by reference numeral 200A is a diagram of the rear cover 2 as seen from the inside of the housing 12, and the diagram indicated by reference numeral 200B is an enlarged view of part A in the diagram indicated by reference numeral 200A.

[0025] As shown in FIG. 2, the rear cover 2 has a plurality of first engagement portions 3 and a plurality of first fitting portions 6 on inner walls 25 at both ends 24a, 24b of the rear cover 2 in the width direction (X direction).

[0026] The first engagement portion 3 includes a plurality of first engagement portions 3a arranged on the left side and a plurality of first engagement portions 3b arranged on the right side when viewed from the display panel 11 side with the rear cover 2 attached to the display panel 11. When the first engagement portions 3a and the first engagement portions 3b are referred to collectively without being distinguished from each other, they are referred to as the first engagement portions 3.

[0027] The first engagement portions 3 engage with second engagement portions 4 provided on the chassis portion 5 inside the opening 121, thereby fixing the rear cover 2 to the display panel 11. With the rear cover 2 attached to the display panel 11, each first engagement portion 3a is positioned to engage with its corresponding second engagement portion 4a, and each first engagement portion 3b is positioned to engage with its corresponding second engagement portion 4b. Details of the engagement between the first engagement portions 3 and the second engagement portions 4 will be described later.

[0028] In the display device 1 according to the present invention, the number of first engagement portions 3a and first engagement portions 3b is, for example, four, but is not particularly limited to this. The arrangement position of the first engagement portion 3 is not limited to the above position, and is not particularly limited as long as it is a position where it can engage with the second engagement portion 4 and where the rear cover 2 elastically deforms when the rear cover 2 is removed. The elastic deformation of the rear cover 2 will be described later.

[0029] (Arrangement of first fitting portion 6) Each first fitting portion 6 is disposed near the first engagement portion 3. The first fitting portions 6 are provided above the first engagement portions 3 (in the Y1 direction). The position of the first fitting portions 6 is not limited to this, and is not particularly limited as long as the first fitting portions 6 can be disengaged from the second fitting portions 7 by the action of removing the rear cover 2. For example, as long as they are near the "first engagement portions 3," they may be below (in the Y2 direction), on the left or right side (in the X direction), or diagonally from the "first engagement portions 3." The action of removing the rear cover 2 will be described later.

[0030] As described above, the first fitting portion 6 fits into the second fitting portion 7 provided on the chassis portion 5, thereby preventing the first engaging portion 3 and the second engaging portion 4 from undesirably disengaging from each other.

[0031] The first fitting portion 6 includes a plurality of first fitting portions 6a provided near the first engaging portion 3a and a plurality of first fitting portions 6b provided near the first engaging portion 3b. When the first fitting portions 6a and the first fitting portions 6b are not distinguished from each other and are referred to collectively as the first fitting portion 6.

[0032] When the rear cover 2 is attached to the display panel 11, each first fitting portion 6a is positioned to fit into the corresponding second fitting portion 7a, and each first fitting portion 6b is positioned to fit into the corresponding second fitting portion 7b.

[0033] The number of first fitting portions 6 is not particularly limited, and for example, two first fitting portions 6 may be arranged on both sides of the first engagement portion 3, or there may be a first engagement portion 3 without a first fitting portion 6. Details of the first fitting portion 6 and its engagement with the second fitting portion 7 will be described later.

[0034] (Arrangement of second engagement portion 4) 3 is a diagram showing an example of the inside of the display device 1 with the rear cover 2 removed. The diagram indicated by reference numeral 300A is a diagram showing the inside of the display device 1 as seen from the rear side of the display device 1, and the diagram indicated by reference numeral 300B is an enlarged view of part B of the diagram indicated by reference numeral 300A.

[0035] As described above, the rear cover 2 is arranged to cover the opening 121 of the housing 12, and by removing the rear cover 2, the inside of the display device 1 can be exposed from the opening 121 of the housing 12, as shown in Fig. 3. At this time, the chassis part 5 located inside the housing 12 is also exposed.

[0036] The chassis 5 is provided with a plurality of second engagement portions 4 and a plurality of second fitting portions 7 at both ends 12a, 12b of the housing 12 in the X direction.

[0037] The second engagement portion 4 includes a plurality of second engagement portions 4a arranged on the left side and a plurality of second engagement portions 4b arranged on the right side when viewed from the display panel 11 side. When the second engagement portions 4a and the second engagement portions 4b are referred to collectively without being distinguished from each other, they are referred to as the second engagement portion 4.

[0038] As described above, each second engagement portion 4a is disposed at a position where it engages with the corresponding first engagement portion 3a when the rear cover 2 is attached to the display panel 11, and each second engagement portion 4b is disposed at a position where it engages with the corresponding first engagement portion 3b. Details of the second engagement portions 4 will be described later.

[0039] The number of second engagement portions 4 may be the same as the number of first engagement portions 3. In addition, the locations of the second engagement portions 4 are not limited to the above positions, and are not particularly limited as long as they are positions that can engage with the first engagement portions 3.

[0040] (Arrangement of second fitting portion 7) Each second fitting portion 7 is disposed near the second engagement portion 4 on the chassis portion 5. The second fitting portion 7 is provided, for example, above the second engagement portion 4 (in the Y1 direction), and fits with the first fitting portion 6 provided on the rear cover 2 as described above.

[0041] The second fitting portion 7 includes a second fitting portion 7a provided near the first engaging portion 3a and a second fitting portion 7b provided near the first engaging portion 3b. When the second fitting portion 7a and the second fitting portion 7b are not distinguished from each other and are referred to collectively as the second fitting portion 7.

[0042] When the rear cover 2 is attached to the display panel 11, each second fitting portion 7a is positioned to fit into the corresponding first fitting portion 6a, and each second fitting portion 7b is positioned to fit into the corresponding first fitting portion 6b.

[0043] The number of second fitting portions 7 is not particularly limited as long as it is the same as the number of first fitting portions 6. Details of the first fitting portions 6 and the fitting between the second fitting portions 7 will be described later.

[0044] In this way, the connecting portion constituted by the first engaging portion 3, the second engaging portion 4, the first fitting portion 6, and the second fitting portion 7 is provided at multiple locations on both ends of the rear cover 2 and the chassis portion 5 in the X direction.

[0045] <Engagement and fitting parts> (First engagement portion 3 and first fitting portion 6) 4 is a perspective view showing an example of the appearance of the first engagement portion 3 and the first fitting portion 6. The view indicated by reference numeral 400A is a perspective view of the first engagement portion 3a and the first fitting portion 6a provided on the inner wall 25 of the rear cover 2 as seen from above (Y2 direction side), and the view indicated by reference numeral 400B is a perspective view of the first engagement portion 3a and the first fitting portion 6a as seen from below (Y1 direction side). The view indicated by reference numeral 400C is a diagram illustrating the inclined portion 312 of the first engagement portion 3.

[0046] In Figure 4, the first engagement portion 3a and the first fitting portion 6a are described, and as the first engagement portion 3b and the first fitting portion 6a are configured symmetrically to the first engagement portion 3a and the first fitting portion 6a, their description will not be repeated unless necessary.

[0047] As shown in FIG. 4, the first engagement portion 3a is provided on the inner wall 25 of the rear cover 2, and includes an engagement piece 31 and a leg portion 32.

[0048] The engagement piece 31 is a portion that engages with the second engagement portion 4, and is formed in a hook shape. Although details will be described later, the engagement piece 31 is formed so as to extend from the central portion 24c side of the rear cover 2 (see FIG. 11) toward the end portion 24a side of the rear cover 2 in a cross section parallel to the first end side 26 of the rear cover 2. The engagement piece 31 of the first engagement portion 3b is formed so as to extend from the central portion 24c side toward the end portion 24b side opposite the first engagement portion 3a.

[0049] The engagement piece 31 includes an engagement surface 311 and an inclined portion 312. The engagement surface 311 is a surface that engages with an engagement surface 431 of the second engagement portion 4, which will be described later.

[0050] As indicated by the reference symbol 400C, the inclined portion 312 is formed on the lower portion (Y2 direction side) of the engagement piece 31, and is formed so that the engagement surface 311, which is the portion that engages with the second engagement portion 4, gradually narrows toward the second end edge 27 side (lower side). The inclined portion 312 is formed to facilitate disengagement between the engagement piece 31 of the first engagement portion 3 and the second engagement portion 4 when the rear cover 2 is removed.

[0051] Here, the upper side (Y1 direction side) of the engagement piece 31 is the first end edge 26 side which becomes the rotation axis when removing the rear cover 2, and the lower side of the engagement piece 31 is the second end edge 27 side of the rear cover 2. When removing the rear cover 2, the second end edge 27 is rotated around the first end edge 26 as the rotation axis so as to move away from the opening 121.

[0052] Therefore, the direction in which the engagement is released is the Y1 direction in the engagement piece 31. In other words, the engagement piece 31 is released from the second engagement portion 4 from the bottom side toward the top side.

[0053] By forming the inclined portion 312 on the lower side where the engagement begins to disengage, the inclined portion 312 can act as a trigger for disengaging with the second engagement portion 4, making it easier to disengage the engagement piece 31 from the second engagement portion 4. Note that the inclined portion 312 is not an essential component, and the first engagement portion 3 does not necessarily have to have the inclined portion 312.

[0054] The leg 32 has a generally flat plate shape and is provided so as to protrude from the inner wall 25 of the rear cover 2 toward the display panel 11. The base end of the leg 32 is continuous with the inner wall 25 of the rear cover 2, and an engagement piece 31 is provided at the tip end opposite the base end.

[0055] The first engagement part 3 is made of the same material as the rear cover 2, for example, a resin such as PC-ABS or HIPS. The first engagement part 3 may be integrally formed with the rear cover 2, or may be manufactured separately from the rear cover 2 and then fixed to the rear cover 2 with an adhesive or the like.

[0056] As described above, the first fitting portion 6a is provided near the first engagement portion 3a of the rear cover 2. The first fitting portion 6a has a protrusion 61 that is inserted into a through-hole 71 of the second fitting portion 7a, which will be described later. The protrusion 61 is formed, for example, in a cylindrical shape, but is not limited to this and may have any shape that can be inserted into the through-hole 71, for example.

[0057] (Second engagement portion 4 and second fitting portion 7) The second engagement portion 4 is a member that engages with the first engagement portion 3, and is provided within the opening 121 of the housing 12. The second engagement portion 4 is provided, for example, on the chassis portion 5 located within the opening 121 of the housing 12, but is not limited to this, and the second engagement portion 4 may be provided on a member other than the chassis portion 5 as long as it is within the opening 121 of the housing 12.

[0058] FIG. 5 is a schematic diagram showing an example of the appearance of the second engagement portion 4a and the second fitting portion 7a. The view indicated by reference numeral 500A is a view of the second engagement portion 4a and the second fitting portion 7a as seen from the rear side of the display device 1. The view indicated by reference numeral 500B is a perspective view of the second engagement portion 4a and the second fitting portion 7a as seen from the bottom (Y2 side). FIG. 6 is a cross-sectional view showing the second engagement portion 4a with a cutout. Note that in FIGS. 5 and 6, the second engagement portion 4a and the second fitting portion 7a will be described, and the second engagement portion 4b and the second fitting portion 7b are configured symmetrically to the second engagement portion 4a and the second fitting portion 7a, so their description will not be repeated unless necessary.

[0059] As shown in FIGS. 5 and 6, the second engagement portion 4a is made of a metal such as aluminum or iron, and includes a notch 45, a folded portion 46, and an engagement surface 431.

[0060] The notch 45 is a portion where the chassis part 5 is cut out, for example, in a U-shape.

[0061] The folded portion 46 is a portion where the cut-out end portion 5a of the chassis portion 5 is folded back toward the rear cover 2 side (Q1 direction) at a folding point 46a.

[0062] The engagement surface 431 is a portion that engages with the engagement surface 311 of the first engagement portion 3, and is a portion that is located near the folding point 46a. The engagement piece 31 of the first engagement portion 3 is inserted into the notch 45 so that the engagement surface 311 of the engagement piece 31 engages with the engagement surface 431 of the second engagement portion 4.

[0063] In this way, the first engagement portion 3 of the rear cover 2 engages with the second engagement portion 4 of the chassis portion 5, thereby fixing the rear cover 2 to the chassis portion 5. Note that the second engagement portion 4 is formed by bending a part of the chassis portion 5, which allows for a reduction in the number of parts, and therefore reduces manufacturing costs and labor.

[0064] The second fitting portion 7a is provided near the second engagement portion 4a and fits into the first fitting portion 6a provided on the rear cover 2. The second fitting portion 7a is, for example, a circular through-hole 71, and is formed so that the diameter is slightly larger than the protrusion 61 of the first fitting portion 6a. This allows the protrusion 61 of the first fitting portion 6a to fit into the through-hole 71 of the second fitting portion 7a.

[0065] As described above, the engagement between the first fitting portion 6 and the second fitting portion 7 prevents the relative positions of the first engaging portion 3 and the second engaging portion 4 from changing due to temperature changes, which prevents the first engaging portion 3 and the second engaging portion 4 from undesirably disengaging from each other. Details of how the engagement between the first fitting portion 6 and the second fitting portion 7 prevents the first engaging portion 3 and the second engaging portion 4 from disengaging from each other will be described later.

[0066] <Installing rear cover 2> FIG. 7 is a schematic diagram illustrating an example of engagement between the first engagement portion 3 and the second engagement portion 4, and engagement between the first fitting portion 6 and the second fitting portion 7 when attaching the rear cover 2 to the chassis portion 5. FIG. 8 is a schematic diagram showing an example of a joined state between the rear cover 2 and the chassis portion 5. The diagram indicated by reference numeral 800A is a cross-sectional view taken along the cross-sectional line VIIIA (see FIG. 7), showing the engaged state of the first engagement portion 3 and the second engagement portion 4. The diagram indicated by reference numeral 800B is a cross-sectional view taken along the cross-sectional line VIIIB (see FIG. 7), showing the engaged state of the first fitting portion 6 and the second fitting portion 7.

[0067] As shown in Figure 7, when attaching the rear cover 2 to the display panel 11 via the chassis portion 5, the engagement piece 31 of the first engagement portion 3 is inserted into the notch 45 of the second engagement portion 4, and the protrusion 61 of the first fitting portion 6 is inserted into the through hole 71 of the second fitting portion 7.

[0068] As shown by the symbol 800A, the engagement surface 311 of the first engagement portion 3 is positioned within the notch 45 of the second engagement portion 4, and the engagement surface 311 of the first engagement portion 3 and the engagement surface 431 of the second engagement portion 4 abut against each other, thereby engaging the first engagement portion 3 and the second engagement portion 4.

[0069] Furthermore, as shown by the reference numeral 800B, the protrusion 61 of the first fitting portion 6 is inserted into the through-hole 71 of the second fitting portion 7, whereby the first fitting portion 6 and the second fitting portion 7 are fitted together.

[0070] When attaching the rear cover 2 to the display panel 11, the worker first places the rear cover 2 over the back side of the display device 1 so that it is approximately parallel to the display panel 11, and engages the third engagement portion 8, which will be described later. Next, working from top to bottom (in the Y2 direction), the worker engages the first engagement portion 3 and the second engagement portion 4 of both end portions 24a, 24b of the rear cover 2, and also fits the first fitting portion 6 and the second fitting portion 7 together.

[0071] In this way, the display device 1 of this embodiment can fix the rear cover 2 to the display panel 11 via the chassis part 5 without using fastening members such as screws, and the rear cover 2 can be attached to the display panel 11.

[0072] <Removing and disengaging the rear cover 2> (Rotational movement of rear cover 2) Fig. 9 is a schematic diagram illustrating an example of rotational movement of the rear cover 2. The diagram indicated by reference numeral 900A in Fig. 9 is a perspective view of the display device 1 as seen from the rear side, and the diagram indicated by reference numeral 900B is a perspective view as seen from the side.

[0073] As shown in Figure 9, the rear cover 2 can be removed by rotating the second end edge 27 of the rear cover 2 around the first end edge 26 of the rear cover 2 as a rotation axis so that the second end edge 27 of the rear cover 2 moves away from the opening 121.

[0074] For example, the rear cover 2 extends to the bottom side of the display device 1 at least in the vicinity of the center 24d, and an operator places a hand on the bottom side of the vicinity of the center 24d of the rear cover 2 and rotates and lifts the rear cover 2 toward the back side of the display device 1. At this time, as the vicinity of the center 24d of the rear cover 2 is lifted, the central portion 24c of the rear cover 2 bends and elastically deforms.

[0075] Furthermore, a notch is formed in the central portion 24c of the rear cover 2, and the length from the first edge 26 to the top of the notch is shorter than the length from the first edge 26 to the second edge 27. Therefore, the force when lifting the rear cover 2 is easily transmitted to the central portion 24c without being dispersed, making it easy to bend the central portion 24c. Note that the rear cover 2 does not have to extend to the bottom side of the display device 1, and the notch 13 does not have to be formed in the central portion 24c of the rear cover 2.

[0076] (Third engagement portion 8) A third engagement portion 8 is provided at the upper end of the display device 1, which engages the first edge 26 of the rear cover 2 with the upper end portion 5b of the chassis portion 5 when the rear cover 2 is closed and when the rear cover 2 is rotated to remove it.

[0077] 10 is a diagram showing an example of the third engagement portion 8. The diagram shown by reference numeral 1000A shows the third engagement portion 81 provided on the rear cover 2 side, and the diagram shown by reference numeral 1000B shows the third engagement portion 82 provided on the chassis portion 5 side.

[0078] 10 , the third engagement portion 8 includes a third engagement portion 81 provided on the first end side 26 side of the rear cover 2, and a third engagement portion 82 provided on the upper end portion 5b of the chassis portion 5. The third engagement portion 81 and the third engagement portion 82 engage with each other, thereby engaging the first end side 26 of the rear cover 2 with the upper end portion 5b of the chassis portion 5.

[0079] As an example, eight third engagement portions 81 and eight third engagement portions 82 are provided at approximately equal intervals (see Figures 2 and 3), but this is not limited to this, and depending on the size, structure, etc. of the display device 1, the number of third engagement portions 81 and eight third engagement portions 82 may be more or less than eight.

[0080] As indicated by the reference numeral 1000A, the third engagement portion 81 has substantially the same configuration as the first engagement portion 3, but is arranged in a different position and direction. Like the first engagement portion 3, the third engagement portion 81 has an engagement piece 811 and a leg portion 813. Unlike the engagement piece 31 of the first engagement portion 3, the third engagement portion 81 is arranged so that the engagement piece 811 extends in the X direction. The engagement piece 811 has an engagement surface 812 that engages with an engagement surface 821 of the third engagement portion 82, which will be described later.

[0081] Furthermore, spacers 83 are arranged near the third engagement portions 81. The spacers 83 are formed, for example, in a cylindrical or columnar shape, and are provided on the inner wall 25 of the rear cover 2. The spacers 83 are arranged to prevent the rear cover 2 from coming too close to the chassis portion 5 when the rear cover 2 is closed. In this embodiment, the spacers 83 are arranged near the four third engagement portions 81 arranged near the center of the rear cover 2 in the X direction, but this is not limiting, and the spacers 83 may be arranged near all of the third engagement portions 81, or may be arranged near fewer than four third engagement portions 81.

[0082] As indicated by reference numeral 1000B, the third engagement portion 82 has substantially the same configuration as the second engagement portion 4, but is arranged at a different position and in a different direction. Like the second engagement portion 4, the third engagement portion 82 is formed by bending a portion of the chassis portion 5, and includes a notch 821, a folded portion 822, and an engagement surface 823. Unlike the folded portion 46 of the second engagement portion 4, which is arranged to extend in the Y direction, the third engagement portion 82 has the folded portion 822 arranged to extend in the X direction.

[0083] The engagement piece 811 of the third engagement portion 81 is inserted into the notch 821 so that the engagement surface 821 of the engagement piece 811 and the engagement surface 823 of the third engagement portion 82 are engaged with each other.

[0084] When the rear cover 2 is rotated, the first edge 26 of the rear cover 2 is engaged with the upper end 5b of the chassis part 5 by the third engagement part 8, but when the rear cover 2 is removed from the chassis part 5, the engaged state of the third engagement part 8 is released. In this way, the third engagement part 8 allows the rear cover 2 to rotate around the first edge 26 as the rotation axis.

[0085] (engage and unmate) 11 is a schematic diagram illustrating an example of movement of the first engagement portion 3 when removing the rear cover 2. The view indicated by reference numeral 1100A in FIG. 11 is a cross-sectional view taken along line XI-XI (see FIG. 9) showing the state before the rear cover 2 is removed. The view indicated by reference numeral 1100B is a cross-sectional view taken along line XI-XI showing the state after the rear cover 2 is removed. Note that line XI-XI is an imaginary plane parallel to the first end side 26 of the rear cover 2.

[0086] As indicated by the reference numeral 1100A, when the rear cover 2 is attached to the display panel 11, the engagement surface 311 of the first engagement portion 3 and the engagement surface 431 of the second engagement portion 4 abut against each other and are engaged with each other. Also, the first fitting portion 6 (not shown) provided on the rear cover 2 is inserted into the second fitting portion 7 (not shown) provided on the chassis portion 5, and the first fitting portion 6 and the second fitting portion 7 are engaged with each other.

[0087] Here, as described above, the engagement piece 31 is formed so as to extend from the central portion 24c side of the rear cover 2 toward the end portion 24a or 24b side of the rear cover 2. Therefore, the direction in which the first engagement portion 3 engages with the second engagement portion 4 is the direction (X direction) from the central portion 24c side toward the end portion 24a or 24b side.

[0088] As shown in the figure indicated by the symbol 1100B, when removing the rear cover 2, the central portion 24c of the rear cover 2 is lifted in the Z2 direction, and the rear cover 2 is rotated away from the opening 121 using the first end edge 26 as the rotation axis.

[0089] When the rear cover 2 is lifted in the Z2 direction, the first fitting portion 6 arranged on the rear cover 2 also moves in the Z2 direction together with the rear cover 2. As a result, the protrusion 61 of the first fitting portion 6, which had been inserted in the Z1 direction into the through-hole 71 of the second fitting portion 7 arranged on the chassis part 5, comes out of the through-hole 71, and the engagement between the first fitting portion 6 and the second fitting portion 7 is released.

[0090] Furthermore, by lifting the rear cover 2 in the Z2 direction, the central portion 24c of the rear cover 2 bends in the P1 direction (Z2 direction), and the ends 24a and 24b bend in the P2 direction (toward the display panel 11). This causes the ends 24a and 24b to move in the P3 direction (X direction). Here, the P3 direction is the direction from the end 24a or 24b side toward the central portion 24c side.

[0091] As the ends 24a and 24b move in the P3 direction, the first engagement portions 3a and 3b provided on the ends 24a and 24b also move in the P3 direction.

[0092] Meanwhile, as described above, the direction in which the first engagement portion 3 engages with the second engagement portion 4 is the direction from the center portion 24c toward the end portion 24a or 24b. The P3 direction is the opposite direction to the engagement direction, and therefore the P3 direction is the direction in which the engagement is released. Therefore, the first engagement portions 3a and 3b move in the direction in which the engagement is released. As a result, the engagement surface 311 of the first engagement portion 3 moves away from the engagement surface 431 of the second engagement portion 4, and the engagement between the engagement surface 311 and the engagement surface 431 is released.

[0093] As a result, an operator can release the engagement between the first fitting portion 6 and the second fitting portion 7 and the engagement between the first engagement portion 3 and the second engagement portion 4, and can remove the rear cover 2, simply by lifting the vicinity of the central portion 24c of the rear cover 2 toward the rear side. In this way, the action of removing the rear cover 2 also releases the engagement and engagement between the rear cover 2 and the chassis portion 5, so a separate action for releasing the engagement and engagement is not required, and the rear cover 2 can be easily removed.

[0094] <Disengagement due to temperature drop> As described above, the rear cover 2 is made of resin such as PC-ABS or HIPS, and the chassis 5 is made of metal such as aluminum or iron.

[0095] The resin rear cover 2 and the metal chassis 5 have different linear expansion coefficients, and therefore, the amounts of contraction and expansion due to temperature changes differ. For example, when the temperature of the place where the display device 1 is placed drops, the resin rear cover 2 contracts more than the metal chassis 5.

[0096] 12 is a schematic diagram illustrating disengagement between the first engagement portion 3 and the second engagement portion 4 due to a temperature drop when the first fitting portion 6 and the second fitting portion 7 are not provided. As shown in FIG. 12, the rear cover 2 and the chassis portion 5 contract in the X1 direction toward the center of the rear cover 2 and the chassis portion 5 due to a temperature change, but the rear cover 2 contracts more than the chassis portion 5.

[0097] 12 shows only the first engagement portion 3b side of the display device 1, but the first engagement portion 3a side is also omitted from the illustration because it contracts in the same manner as the first engagement portion 3b side. In the case of the first engagement portion 3a side, the rear cover 2 and the chassis portion 5 contract in the X2 direction, which is the opposite direction from the first engagement portion 3b side, toward the center of the rear cover 2 and the chassis portion 5.

[0098] As a result, the first engagement portion 3b provided on the rear cover 2 moves further than the second engagement portion 4b in the direction from the end portion 24b toward the central portion 24c of the rear cover 2, that is, in the P3 direction (X1 direction) which is the direction in which the engagement is released. As a result, the engagement surface 311 of the first engagement portion 3 moves away from the engagement surface 431 of the second engagement portion 4, and the engagement between the engagement surface 311 and the engagement surface 431 is released.

[0099] As a result, at least a portion of the rear cover 2 may come off the chassis 5, causing the rear cover 2 to float up in the Z2 direction, resulting in a gap W between the rear cover 2 and the chassis 5.

[0100] In order to prevent the engagement between the first engagement portion 3 and the second engagement portion 4 from undesirably coming loose, the display device 1 of the present invention is provided with an engagement structure for the first engagement portion 3 and the second engagement portion 4, as well as an engagement structure for the first fitting portion 6 and the second fitting portion 7.

[0101] As described above, the protrusion 61 of the first fitting portion 6 is inserted into the through hole 71 of the second fitting portion 7, so even if the rear cover 2 and the chassis portion 5 shrink, the protrusion 61 of the first fitting portion 6 will not come out of the through hole 71 of the second fitting portion 7. This restricts movement of the relative positions of the first engaging portion 3 and the second engaging portion 4 due to temperature changes, and makes it possible to maintain the engaged state between the first engaging portion 3 and the second engaging portion 4.

[0102] [Modification] The first fitting portion 6 may have an axial length L of the protrusion 61A that is long enough to prevent interference with other components.

[0103] 13 is a schematic diagram showing an example of a first fitting portion 6A in which the axial length L of the protrusion 61A is longer than that of embodiment 1. The diagram indicated by reference numeral 1300A is a perspective view showing the first fitting portion 6A, and the diagram indicated by reference numeral 1300B is a schematic diagram showing the first fitting portion 6A in an engaged state.

[0104] 13, the axial length L of the protrusion 61A is configured to be L1 longer than that of the protrusion 61. The axial length of the protrusion 61 of the first fitting portion 6 only needs to be long enough to expose the tip of the protrusion 61 from the through-hole 71 of the second fitting portion 7.

[0105] When a worker attaches the rear cover 2 to the chassis 5, the worker places the rear cover 2 on the rear side of the chassis 5 and performs the work with the rear side of the rear cover 2 facing the worker. Therefore, the first engaging portion 3, the second engaging portion 4, the first fitting portion 6, and the second fitting portion 7 are not visible to the worker.

[0106] By increasing the axial length L of the protrusion 61A, the first fitting portion 6A and the second fitting portion 7 can be used to align the rear cover 2 when attaching the rear cover 2. Specifically, by inserting the protrusion 61A of the first fitting portion 6A into the through-hole 71 of the second fitting portion 7 before the engagement between the first engagement portion 3 and the second engagement portion 4 is completed, the rear cover 2 can be aligned to the correct position relative to the chassis portion 5. After inserting the protrusion 61A of the first fitting portion 6A into the through-hole 71, the worker can engage the first engagement portion 3 and the second engagement portion 4 simply by closing the rear cover 2, thereby improving work efficiency.

[0107] The first fitting portions 6A having a long axial length L may be applied to all of the first fitting portions 6, or may be applied to at least some of the first fitting portions 6.

[0108] [Embodiment 2] A second embodiment of the present invention will be described below. For ease of explanation, in the second embodiment and the following embodiments, the same reference numerals will be used to designate components having the same functions as those described in the first embodiment, and the description thereof will not be repeated.

[0109] The first fitting portion 6 of the first embodiment has one cylindrical or other protruding portion 61, but the first fitting portion 6B of the second embodiment has, instead of the protruding portion 61, a plurality of ribs 62B arranged radially.

[0110] Fig. 14 is a schematic diagram showing an example of a first fitting portion 6B according to embodiment 2.

The number of ribs 62B is not particularly limited and may be three or five or more.

[0112] The second fitting portion 7B is provided near the second engagement portion 4 of the rear cover 2 and includes a protrusion 72B that is inserted into the housing portion 63B. The protrusion 72B is realized, for example, by a cylindrical boss or the like, but is not limited to this and may be any member that can be inserted into the housing portion 63B, such as a cylindrical or rectangular prism-shaped member. The second fitting portion 7B may be attached to the chassis portion 5 by, for example, crimping, or by welding, screws, or the like.

[0113] The protrusion 72B is inserted into the accommodation portion 63B, and the protrusion 72B and the rib 62B are fitted together, whereby the first fitting portion 6B and the second fitting portion 7B are fitted together.

[0117] The second fitting portion 7C is provided near the second engaging portion 4 of the chassis portion 5 and includes a protrusion 72C. The protrusion 72C is realized by, for example, a cylindrical boss, and may be attached to the chassis portion 5 by, for example, crimping, or by welding, screws, or the like.

[0118] When the protrusion 72C of the second fitting portion 7C is inserted into the accommodating portion 63C of the first fitting portion 6C, the outer peripheral surface of the protrusion 72C and the inner peripheral surface of the protrusion 61C are fitted together.

[0119] [Embodiment 4] The first fitting portion 6C of embodiment 3 has a protrusion 61C that fits into the outer peripheral surface of the second fitting portion 7C, while the first fitting portion 6D of embodiment 4 has a protrusion 61D that fits into the inner peripheral surface of the second fitting portion 7D.

[0120] FIG. 17 is a schematic diagram illustrating an example of fitting between the first fitting portion 6D and the second fitting portion 7D according to the fourth embodiment when the rear cover 2 is attached to the chassis portion 5. As shown in FIG.

[0121] 17, the first fitting portion 6D is provided near the first engagement portion 3 and includes a protrusion 61D. The protrusion 61D is configured in a pin shape and is inserted into a receiving portion 63D of the second fitting portion 7D, which will be described later.

[0122] The second fitting portion 7D is provided near the second engaging portion 4 of the chassis portion 5 and includes a protrusion 72D. The protrusion 72D is realized by, for example, a cylindrical boss or the like and includes a housing portion 63D into which the protrusion 61D is inserted. The protrusion 72D may be attached to the chassis portion 5 by, for example, crimping, or may be attached to the chassis portion 5 by welding, screws, or the like.

[0123] When the protrusion 61D of the first fitting portion 6D is inserted into the accommodating portion 63D of the second fitting portion 7D, the inner circumferential surface of the protrusion 72D and the outer circumferential surface of the protrusion 61D are fitted together.

[0124] 〔summary〕 A housing structure according to a first aspect of the present invention comprises an opening, a cover member covering the opening, a specified part disposed within the opening and having a linear expansion coefficient different from that of the cover member, a first engagement portion provided on the cover member, a second engagement portion provided on the specified part and engaging with the first engagement portion, a first fitting portion disposed near the first engagement portion on the cover member, and a second fitting portion disposed near the second engagement portion on the specified part and fitting with the first fitting portion.

[0125] According to the above configuration, by engaging the first engaging portion with the second engaging portion, movement of the relative positions of the first engaging portion and the second engaging portion due to temperature changes can be restricted, and the engaged state of the first engaging portion and the second engaging portion can be maintained.

[0126] A housing structure according to aspect 2 of the present invention is such that, in the above-mentioned aspect 1, the specified part is a plate-like member extending across both widthwise ends of the opening, the first engagement portion and the second engagement portion are provided at the ends of the cover member and the specified part, the cover member and the specified part shrink toward the center of the cover member and the specified part due to temperature changes, and the cover member may shrink more than the specified part.
