[0009] (Configuration of display device 1) Fig. 1 is a front view showing the front of a display device 1 according to one embodiment of the present invention. Fig. 2 is a rear view showing the rear of the display device 1. As shown in these figures, the display device 1 includes a display panel 2, a back chassis 3, and a cover 4.

[0010] The display panel 2 displays various types of information such as text, images, and videos on the screen of the display panel 2. The display panel 2 may be, for example, a liquid crystal display panel or an organic EL panel. The back chassis 3 is arranged on the back of the display panel 2. The back chassis 3 fixes the display panel 2 and mounts various components (power supply, drive circuits, etc.) for operating the display panel 2 on the back side of the back chassis 3. The cover 4 is arranged on the back of the back chassis 3. The cover 4 covers various back components arranged on the back of the display device 1. In this embodiment, the cover 4 is arranged in a position on the back chassis 3 near the top end of the display device 1.

[0011] FIG. 3 is a rear view showing the rear of the display device 1 with the cover 4 removed. As shown in this figure, the display device 1 further includes a fixing bracket 5, a reinforcing bracket 6, a left speaker unit 11 (rear member), and a right speaker unit 12 (rear member). All of these components are located on the rear side of the display device 1 in the back chassis 3. The left speaker unit 11 and the right speaker unit 12 are fixed to the fixing bracket 5 by being screwed into the fixing bracket 5. When the cover 4 is attached to the display device 1, the cover 4 covers the left speaker unit 11, the right speaker unit 12, and the fixing bracket 5. In this way, the cover 4 protects the left speaker unit 11 and the right speaker unit 12.

[0012] The reinforcing metal fittings 6 reinforce the back chassis 3. The reinforcing metal fittings 6 are arranged in a position on the back chassis 3 closer to the bottom end of the display device 1 than the fixing metal fittings 5. The reinforcing metal fittings 6 include two positioning protrusions 61 and one protruding edge 62. Each of the positioning protrusions 61 is arranged at a different position on the reinforcing metal fittings 6 along the lateral direction of the display device 1. They protrude from the back chassis 3 toward the rear of the display panel 2. The protruding edge 62 protrudes from the back chassis 3 toward the rear of the display panel 2, and is arranged in a position overlapping with the positioning protrusion 61 at least in the left-right direction of the display panel 2. The positioning protrusions 61 and the protruding edge 62 are used to determine the attachment position of the cover 4 when attaching the cover 4 to the back chassis 3. Details will be described later.

[0013] In this embodiment, the reinforcing metal fittings 6 can be said to constitute part of the back chassis 3. Therefore, it can be said that the back chassis 3 includes all of the members that the fixing metal fittings 5 ​​include.

[0014] (Details of cover 4) 4 is a diagram showing a detailed configuration of the cover 4. As shown in this figure, the cover 4 includes two positioning portions 41 each having a positioning hole 42, four engagement portions 43 (first engagement portions), two engagement portions 44, two engagement portions 45 (second engagement portions), one engagement portion 46 (third engagement portion), two ribs 47, and two guide portions 48 (contact portions).

[0015] The engagement portions 43 to 46 and the rib 47 are all formed at positions on the cover 4 that are more inward than the periphery of the cover 4. More specifically, the engagement portions 43 and 44 are both formed at the top end (end in the first direction) of the cover 4. The two engagement portions 45 are individually formed at the left end (end in the second direction) and right end (end in the second direction) of the cover 4. The engagement portion 46 is formed at a position on the cover 4 that is closer to the center of the cover 4 than the top end of the cover 4. The two ribs 47 are individually formed at the left end and right end of the cover 4.

[0016] Both the engagement portion 43 and the engagement portion 44 extend in the vertical direction of the display panel 2. The engagement portion 45 extends in the horizontal direction of the display panel 2. The vertical direction here refers to a direction (first direction) parallel to the surface direction of the display panel 2, and the horizontal direction refers to a direction (second direction) parallel to the surface direction of the display panel 2 and perpendicular to the vertical direction. The engagement portion 46 protrudes from the rear surface of the cover 4 and extends from the end of the protrusion in the vertical direction of the display panel 2 of the cover 4.

[0017] The positioning portion 41 is formed on the cover 4 outside the periphery of the cover 4. More specifically, the positioning portion 41 extends from the lower end of the cover 4 toward the lower side of the display panel 2. The positioning hole 42 extends in the vertical direction of the display panel 2 at the center position in the width direction of the positioning portion 41. In other words, the positioning hole 42 has an oval shape that is elongated in the vertical direction of the display panel 2. The width of the positioning hole 42 is approximately 1.5 times the width of the positioning protrusion 61.

[0018] (Details of fixing bracket 5) FIG. 5 is a diagram showing the detailed configuration of the fixing bracket 5. As shown in this figure, the fixing bracket 5 has two claws 51 (first engaged portions), one claw 52, ​​two claws 53 (second engaged portions), and one peak 54 (third engaged portion). The claws 51 and 52 are both formed at the upper end of the fixing bracket 5. The claw 52 is formed at a position sandwiched between the pair of claws 51. The pair of claws 53 are each formed individually at the left and right ends of the fixing bracket 5. The peak 54 is formed at a position on the fixing bracket 5 closer to the center of the fixing bracket 5 than the upper end of the fixing bracket 5. In other words, the peak 54 is located at a position farther away from the claws 51 on the back chassis 3 in the up-down direction of the display panel.

[0019] 6 is a side view showing the side of the fixing bracket 5 as seen from the right end of the fixing bracket 5. As shown in this figure, the claw portion 51 has a protruding portion 51A that protrudes from the back chassis 3 toward the back of the display panel 2, and an extending portion 51B that extends in the vertical direction of the display panel 2 from a position on the protruding portion 51A that is distant from the back chassis 3. The claw portion 53 has a protruding portion 53A that protrudes from the back chassis 3 toward the back of the display panel 2, and an extending portion 53B that extends in the vertical direction of the display panel 2 from a position on the protruding portion 53A that is distant from the back chassis 3.

[0020] 7 is a cross-sectional view showing a cross section at the center position in the left-right direction of the fixing bracket 5. As shown in this figure, the claw portion 52 has a protruding portion 52A that protrudes from the back chassis 3 toward the back surface of the display panel 2, and an extending portion 52B that extends in the up-down direction of the display panel 2 from a position on the protruding portion 52A away from the back chassis 3.

[0021] 5, the mountain portion 54 has a protruding portion 54A that protrudes from the back chassis 3 toward the back of the display panel 2, and an extending portion 54B that extends in the left-right direction of the display panel 2 from a position on the protruding portion 54A that is away from the back chassis 3. The mountain portion 54 is formed in a mountain shape by cutting out a part of the fixing bracket 5.

[0022] In this embodiment, the fixing metal fittings 5 ​​constitute a part of the back chassis 3. Therefore, it can be said that the back chassis 3 includes all of the components that the fixing metal fittings 5 ​​include.

[0023] (Installing cover 4) FIG. 8 is a diagram illustrating the procedure for attaching the cover 4. A worker in charge of assembling the display device 1 (hereinafter referred to as the worker) attaches the cover 4 to the back chassis 3 by moving the cover 4 from the top to the bottom of the display panel 2 in a vertical direction parallel to the surface of the display panel 2. When attaching the cover 4 to the back chassis 3, the worker first positions the cover 4 in a position that completely covers the left speaker unit 11 and other components on the back of the display panel 2. Specifically, as shown in FIG. 8, while visually checking the pair of positioning portions 41 at the bottom end of the cover 4, the worker positions the cover 4 so that each of the pair of positioning portions 41 is positioned directly above the corresponding positioning protrusions 61 in the vertical direction of the display panel 2. At this stage, the positioning protrusions 61 are not inserted into the positioning holes 42.

[0024] FIG. 9 is a diagram illustrating the procedure for attaching the cover 4. Next, the worker moves the cover 4, which is positioned as shown in FIG. 8, further downward, thereby inserting each of the pair of positioning protrusions 61 into the lowest portion of the corresponding positioning hole 42. In the state shown in FIG. 9, when a force is applied to the cover 4 to move it in the left-right direction of the display panel 2, the positioning protrusions 61 get caught on the positioning parts 41, limiting the movement in the left-right direction. This allows the attachment position of the cover 4 in the left-right direction of the display panel 2 to be accurately determined.

[0025] FIG. 10 is a diagram illustrating the procedure for attaching the cover 4. Next, the worker further moves the cover 4, which is positioned as shown in FIG. 8, downward until each of the pair of positioning protrusions 61 reaches the uppermost portion of the corresponding positioning hole 42. As a result, on the inside of the cover 4, each of the engagement portions 43 to 46 engages with each of the corresponding claw portions 51 to 54. Details of these engagements will be described later. After attaching the cover 4 to the back chassis 3 as shown in FIG. 10, the worker fixes the cover 4 by screwing it to the reinforcing metal fittings 6.

[0026] 11 is a diagram illustrating the procedure for attaching the cover 4. When the cover 4 is moved to the position shown in FIG. 10, the guide portions 48 of the cover 4 come into contact with the protruding edges 62 of the reinforcing metal fittings 6 in the vertical direction of the display panel 2. In this state, even if an attempt is made to move the cover 4 further downward, the guide portions 48 are obstructed by the protruding edges 62, preventing the cover 4 from moving further downward. This determines the vertical position of the cover 4 relative to the back chassis 3.

[0027] Fig. 12 is a diagram showing the cover 4 and the fixing bracket 5 before the cover 4 is attached. When the cover 4 is placed in the position shown in Fig. 10, the engagement portions 43 to 46 are positioned immediately adjacent to the corresponding claw portions 51 to 54, as shown in Fig. 12. At this stage, the engagement portions 43 to 46 are not engaged with the corresponding claw portions 51 to 54.

[0028] 13 is a diagram showing the cover 4 and the fixing bracket 5 in a state in which the cover 4 is attached. When the cover 4 is moved downwards on the display panel 2 to the position shown in FIG. 10, the engagement portions 43 to 46 individually engage with the corresponding claw portions 51 to 54, as shown in FIG. 13. At this time, the two ribs 47 each come into contact with an abutment surface formed on the right and left ends of the fixing bracket 5. This makes it possible to more reliably position the cover 4 in the up-down direction of the display panel 2.

[0029] 14 is a diagram showing engagement of the engagement portion 43 with the claw portion 51. As shown in this figure, the engagement portion 43 engages with the claw portion 51 by being inserted into a gap between the extended portion 51B of the claw portion 51 and the back chassis 3. The engagement portion 43 protrudes toward the back surface of the display panel 2 and has a plurality of extended sides 43A that extend in the up-down direction of the display panel 2. The engagement portion 43 engages with the claw portion 51 by having the extended sides 43A abut against the extended portions 51B of the claw portion 51.

[0030] The height of the engaging portion 43 may be increased so that the engaging portion 43 can abut against the extending portion 51B of the claw portion 51 without forming multiple extending side portions 43A on the engaging portion 43. However, in this case, there is a possibility that the engaging portion 43 may be partially deformed or collapsed during the manufacture of the cover 4. On the other hand, if multiple elongated extending side portions 43A are formed on the engaging portion 43, each extending side portion 43A can be accurately formed in a desired shape during the manufacture of the cover 4.

[0031] 15 is a diagram showing engagement of the engagement portions 43 with the claw portions 52. As shown in this figure, the remaining two engagement portions 43 are engaged with the claw portions 52 by being inserted into gaps between the extended portions 52B of the claw portions 52 and the back chassis 3. These two engagement portions 43 also have a plurality of extended side portions 43A that protrude toward the back surface of the display panel 2. The engagement portions 43 are engaged with the claw portions 52 by having the extended side portions 43A abut against the extended portions 52B of the claw portions 52.

[0032] 16 is a diagram showing engagement of the engagement portions 44 with the claw portions 52. As shown in this figure, the two engagement portions 44 are engaged with the claw portions 52 by being inserted into the gap between the extension portions 52B of the claw portions 52 and the back chassis 3. Unlike the engagement portion 43, the engagement portions 44 do not have protruding sides. Therefore, the engagement portions 44 are engaged with the claw portions 52 by having the flat surfaces of the engagement portions 44 abut against the extension portions 52B of the claw portions 52.

[0033] 17 is a diagram showing engagement of the engagement portions 45 with the claw portions 53. As shown in this figure, the two engagement portions 45 are engaged with the claw portions 53 by being inserted into the gap between the extension portions 53B of the claw portions 53 and the back chassis 3.

[0034] 18 is a diagram showing engagement of the engagement portion 46 with the mountain portion 54. As shown in this figure, the engagement portion 46 engages with the mountain portion 54 by being inserted into the gap between the extended portion 54B of the mountain portion 54 and the back chassis 3.

[0035] (Major effects) When attaching the cover 4 to the back chassis 3, the positioning protrusions 61 can be inserted into the positioning holes 42 of the positioning portions 41 to accurately position the cover 4 in the left-right direction of the display panel 2. Because the positioning holes 42 and the positioning protrusions 61 are both formed on the outside of the cover 4, an operator can visually check them and reliably position the cover 4 accurately in the left-right direction. At this time, the engaging portions 43 to 46 on the inside of the cover 4 are automatically positioned immediately adjacent to the corresponding claws 51 to 54. Therefore, when the cover 4 is moved downward on the display panel 2 in this state, the engaging portions 43 to 46 on the inside of the cover 4 can be reliably engaged with the corresponding claws 51 to 55. As a result, the cover 4 can be reliably attached to the predetermined position in the up-down direction of the display panel 2.

[0036] As described above, even if the worker cannot visually check the engagement points between the cover 4 and the fixing metal fittings 5, the worker can accurately attach the cover 4 to the back chassis 3. Therefore, the cover 4 can be attached to the back chassis 3 more reliably.

[0037] After the cover 4 is attached, the mountain portion 54 engages with the mountain-shaped claw portion 52 at a position close to the center of the cover 4. This prevents the cover 4 from separating in the rear direction from the back chassis 3. Therefore, it is possible to prevent a gap from being generated between the cover 4 and the back chassis 3 after the cover 4 is attached.

[0038] The cover 4 is engaged with the fixing brackets 5 not only at the top end of the cover 4 but also at the right and left ends of the cover 4. This increases the number of engagement points when attaching the cover 4, allowing the cover 4 to be more securely attached to the back chassis 3. Furthermore, after the cover 4 is attached, it is possible to prevent gaps from being formed between the cover 4 and the back chassis 3 at the right and left ends of the cover 4.

[0039] Because the width of the positioning holes 42 is larger than the width of the positioning protrusions 61, there is a certain amount of leeway in the left-right direction of the cover 4 at which the positioning protrusions 61 can be inserted into the positioning holes 42. Therefore, when attaching the cover 4, the worker can more easily insert the positioning protrusions 61 into the positioning holes 42. Furthermore, when moving the cover 4 downward, the positioning protrusions 61 are less likely to get caught on the positioning parts 41, so the cover 4 can be moved downward smoothly.

[0040] (Variation) The claw portions 51 to may be formed on the back chassis 3 instead of on the fixing metal fittings 5. That is, the back chassis 3 may be provided with the claw portions 51 to .

[0041] The positioning protrusion 61 and the protruding side portion 62 may be formed on the back chassis 3 instead of on the reinforcing metal fitting 6. That is, the back chassis 3 may be provided with the positioning protrusion 61 and the protruding side portion 62.

[0042] The width of the positioning hole 42 may be approximately the same as the width of the positioning protrusion 61. In this example, after the positioning protrusion 61 is inserted into the positioning hole 42, the cover 4 cannot be moved in the left-right direction of the display panel 2. Therefore, the left-right position of the cover 4 can be positioned in the most ideal position.

[0043] The cover 4 may be configured to be attached to the back chassis 3 by moving it in the left-right direction of the display panel 2. For example, the cover 4 may be configured to be attached to the back chassis 3 by moving it from the right side to the left side of the display panel 2. In this example, the cover 4, the fixing bracket 5, and the reinforcing bracket 6 described above may be rotated by 90° and then placed on the back surface of the back chassis 3.
