FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, a display device as an example of a device according to an embodiment of the present disclosure will be described with reference to the drawings. In the drawings, the same or equivalent elements are designated by the same reference numerals, and redundant description will not be repeated.

[0010] (Embodiment 1) A display device 10 as an example of the device according to the first embodiment will be described with reference to FIGS.

[0011] Fig. 1 is a perspective view of a display device 10 according to the present embodiment. Fig. 2 is a rear view of the display device 10 according to the present embodiment. Fig. 3 is a rear view showing a state in which a speaker cover 7 and a back cover 8 have been removed from the display device 10 according to the present embodiment. Fig. 4 is a partial rear view showing a state in which the speaker cover 7, the back cover 8, and the speaker 6 have been removed from the display device 10 according to the present embodiment, showing a state in which the speaker 6 has been removed from the state shown in Fig. 3.

[0012] 1 to 4, a display device 10 of the present embodiment includes a display panel 1, a chassis 2, a magnet 3, a mounting member 4, male screws 5, a speaker 6 (an example of a component), a speaker cover 7, and a back cover 8. Descriptions of components other than these will be omitted.

[0013] The display device 10 of the present embodiment is a display as a television receiver that receives radio waves and displays an image or video. However, the display device 10 may be a display that displays an image or video specified by a command signal transmitted from a computer. The display device 10 may be a display of a desktop computer, or may be a display of a notebook computer. The display device 10 may be a display of a mobile phone, a watch, or a signage.

[0014] The display panel 1 of this embodiment is rectangular and plate-like, and has a screen on its front surface. In this embodiment, the display panel 1 is a liquid crystal display panel that displays images or videos on the screen under the control of a control device.

[0015] However, the display panel 1 may be an OLED (Organic Light-Emitting Diode) display panel or a QLED (Quantum dot Light Emitting Diode) display panel. The display panel 1 may be any panel that can display an image or video by being controlled by a control device (not shown).

[0016] The chassis 2 is provided on the rear side of the display panel 1. The chassis 2 is provided so as to face the display panel 1. The chassis 2 is rectangular and has a plate shape. The chassis 2 is made of a magnetic material. Specifically, the chassis 2 is made of a metal such as iron.

[0017] The chassis 2 may be a frame of a device in a general sense. Therefore, the chassis 2 may be provided in any device as long as it supports members.

[0018] Each of the two magnets 3 is fixed to the mounting member 4 by two male screws 5. The magnets 3 are in contact with the rear surface of the chassis 2. As a result, the chassis 2 and the mounting member 4 are fixed in position relative to each other via the magnets 3.

[0019] The speaker 6 of this embodiment emits sound diagonally upward and forward (toward the display panel 1) of the display device 10. The rear surface of the speaker 6 is covered with a resin speaker cover 7. The rear surface below the speaker cover 7 of the chassis 2 is covered with a resin back cover 8.

[0020] 5 and 6 are respectively a front view and a rear view showing the magnet 3, the mounting member 4, and the male screw 5 of the display device 10 of the present embodiment. FIG. 7 is a partial horizontal cross-sectional view of the display device 10 of the present embodiment, taken along the line VII-VII in FIG. 6. FIG. 8 is an enlarged view of the area surrounded by the dashed line VIII in FIG. 7. FIG. 9 is a partial vertical cross-sectional view of the display device 10 of the present embodiment, taken along the line IX-IX in FIG. 6.

[0021] Figures 10 and 11 are respectively a first perspective view and a second perspective view of magnet 3 of display device 10 of the present embodiment. Figures 12 and 13 are respectively a first perspective view and a second perspective view of mounting member 4 of display device 10 of the present embodiment.

[0022] Hereinafter, the magnet 3, the mounting member 4, and the male screw 5 of the display device 10 of the embodiment will be described with reference to FIGS.

[0023] The magnet 3 has a protruding portion 3a and a flange portion 3b. The protruding portion 3a is rectangular and flat. The flange portion 3b extends outward from the outer periphery of the rectangle of the protruding portion 3a. The magnet 3 can magnetize the magnetic material that constitutes the chassis 2 by coming into contact with the chassis 2.

[0024] The protruding portion 3a of the magnet 3 is inserted into the opening 4op of the mounting member 4 so as to contact the chassis 2. In other words, the protruding portion 3a of the magnet 3 protrudes from the rear side of the mounting member 4 to the front side of the mounting member 4 through the opening 4op. However, the magnet 3 does not protrude significantly forward from the front surface of the mounting member 4. This makes it possible to prevent the space between the chassis 2 and the mounting member 4 from becoming too large.

[0025] According to the above configuration, the magnet 3 can be positioned relative to the mounting member 4 simply by inserting the protruding portion 3a into the opening 4op. Therefore, the magnet 3 can be easily positioned relative to the mounting member 4.

[0026] The magnet 3 includes a frame-shaped flange 3b provided so as to surround the periphery of the protrusion 3a. The flange 3b is provided so as to extend along the back surface of the mounting member 4. The flange 3b is in contact with the back surface of the mounting member 4. In other words, the flange 3b is engaged with the peripheral edge of the opening 4op of the mounting member 4 on the back surface side of the mounting member 4. Therefore, the magnet 3 is prevented from slipping out of the opening 4op toward the chassis 2.

[0027] The flange portion 3b is screwed to the mounting member 4. Specifically, the flange portion 3b has a flange through hole 3bth. The mounting member 4 has a female screw hole 4sh. A male screw 5 is inserted into the flange through hole 3bth and is screwed into the female screw hole 4sh. This allows the magnet 3 to be fixed to the mounting member 4. Therefore, even if a large force is generated in a direction parallel to the contact surface between the magnet 3 and the mounting member 4, it is possible to suppress misalignment between the mounting member 4 and the magnet 3.

[0028] However, the flange 3b does not have to be provided so as to surround the entire circumference of the protruding portion 3a. The flange 3b may protrude from only a part of the entire circumference of the protruding portion 3a. The flange 3b may have any shape as long as it is a shape that can be engaged with the peripheral portion of the opening 4op.

[0029] The flange portion 3b may be fixed to the mounting member 4 by a joining member such as a nail, a rivet, or a bolt instead of the male screw 5. The flange portion 3b may also be fixed to the mounting member 4 by a joining method that does not use a fixing member, such as welding, adhesion, or bonding.

[0030] The mounting member 4 is provided on the rear side of the chassis 2. The mounting member 4 is a member provided along a part of the rear side of the chassis 2. In this embodiment, the mounting member 4 is made of a magnetic material such as metal. Therefore, in this embodiment, the magnet 3 is positioned on the mounting member 4 by being attracted by magnetic force. Therefore, the magnet 3 is difficult to detach from the mounting member 4.

[0031] However, the mounting member 4 may be formed of a non-magnetic material such as resin. In other words, the mounting member 4 may be anything to which the magnet 3 can be attached. Furthermore, the magnet 3 may be attached to the mounting member 4 in any manner.

[0032] In this embodiment, the mounting member 4 is made of a magnetic material. This allows the magnet 3 to be fixed to the mounting member 4 by magnetic force. Therefore, in this embodiment, fixing the magnet 3 to the mounting member 4 by the male screw 5 is not essential. However, when the mounting member 4 is made of a non-magnetic material such as resin, it is preferable to fix the magnet 3 to the mounting member 4 by a joining member such as a male screw, nail, rivet, or bolt, or by a method such as welding, melting, or adhesion.

[0033] The mounting member 4 has an opening 4op for receiving the magnet 3. The opening 4op has a rectangular shape. In this embodiment, the magnet 3 includes a protrusion 3a having a rectangular flat plate shape. The protrusion 3a has a rectangular flat plate shape similar to the rectangular shape of the opening 4op. In addition, the gap between the opening 4op and the protrusion 3a is small. Therefore, deviation in the relative positioning of the magnet 3 and the mounting member 4 is unlikely to occur. However, the magnet 3 and the opening 4op may have any shape.

[0034] A speaker 6 is attached to the mounting member 4 as an example of a part that can be attached to the mounting member 4. However, the mounting member 4 may be a member to which any part other than the speaker 6 can be attached, so long as it is a member to which any part can be attached.

[0035] In the display device 10 of the present embodiment described above, the chassis 2 and the mounting member 4 are fixed in position relative to each other by the magnetic force between the magnetic material constituting the chassis 2 and the magnet 3 attached to the mounting member 4. Therefore, the chassis 2 and the mounting member 4 can be fixed in position only by the magnet 3 attached to the mounting member 4, without the need to attach any new parts to the chassis 2. Therefore, the number of parts of the display device 10 can be reduced.

[0036] Furthermore, in the display device 10 of the present embodiment, the chassis 2 and the mounting member 4 are fixed in position only by the magnetic force between the magnetic body constituting the chassis 2 and the magnet 3 attached to the mounting member 4. Therefore, the relative positional relationship between the chassis 2 and the mounting member 4 can be easily fine-tuned.

[0037] (Embodiment 2) 14 to 21, a display device 10 will be described as an example of a device according to the second embodiment. Note that, in the following, description of the same points as those of the display device 10 according to the first embodiment will not be repeated. The display device 10 according to the present embodiment differs from the display device 10 according to the first embodiment in the following points.

[0038] 14 is a rear view showing the mounting member 4, magnet holder 9, and male screw 5 of the display device 10 of the present embodiment. The front view showing the magnet 3, magnet holder 9, and male screw 5 of the display device 10 of the present embodiment is the same as FIG.

[0039] As can be seen from Fig. 14 and Fig. 5 used in the description of the first embodiment, the display device 10 of this embodiment is similar to the display device 10 of the first embodiment in that the mounting member 4 is provided with an opening 4op into which a magnet 3 is inserted. However, the display device 10 of this embodiment differs from the display device 10 of the first embodiment in that it is provided with a magnet holder 9.

[0040] Fig. 15 is a partial horizontal cross-sectional view of the display device 10 of the present embodiment, taken along line XV-XV in Fig. 14. Fig. 16 is an enlarged view of an area surrounded by dashed line XVI in Fig. 15. Fig. 17 is a partial vertical cross-sectional view of the display device 10 of the present embodiment, taken along line XVII-XVII in Fig. 14.

[0041] Figures 18 and 19 are respectively a first and second perspective view of magnet holder 9 of display device 10 of the present embodiment. Figures 20 and 21 are respectively a first and second perspective view of magnet 3 of display device 10 of the present embodiment.

[0042] Hereinafter, the magnet 3, the mounting member 4, and the male screw 5 of the display device 10 of the embodiment will be described with reference to FIGS.

[0043] The magnet holder 9 holds the magnet 3 so that the protruding portion 3a of the magnet 3 is in contact with the chassis 2 with the magnet 3 inserted into the opening 4op. The magnet holder 9 is made of a resin such as PC / ABS (Poly-Carbonate / Acrylonitrile Butadiene Styrene), i.e., a non-magnetic material. As a result, the magnet holder 9 does not generate magnetic force, and the magnet 3 can be easily attached to the mounting member 4 made of a magnetic material by the magnet holder 9. However, the magnet holder 9 may be made of a magnetic material.

[0044] The magnet holder 9 includes a rectangular cover portion 9a. The cover portion 9a has a recess 3x formed therein so as to cover the rear side of the protruding portion 3a of the magnet 3. The recess 3x provided on the front surface of the cover portion 9a allows the magnet 3 to be easily positioned relative to the magnet holder 9.

[0045] The magnet holder 9 has hook portions 9b bent from two opposing sides of the cover portion 9a. The hook portions 9b are provided along the long sides of the rectangular cover portion 9a. The hook portions 9b are used to hold the magnet 3. The hook portions 9b engage with the flange portion 3b of the magnet 3, which will be described later. Therefore, the hook portions 9b enable the magnet holder 9 to easily hold the magnet 3.

[0046] The flange 3b of the magnet 3 of this embodiment differs from the flange 3b of the first embodiment in that it extends along the chassis 2 from only a part of the entire circumference of the protrusion 3a. Specifically, the magnet 3 has a long and thin plate-like flange 3c, rather than a frame-like flange 3b. The two flanges 3c are provided so as to extend along the two long sides of the rectangle, respectively.

[0047] Two flanges 3b extending in opposite directions are inserted into two hooks 9b that bend to face each other. Therefore, the two flanges 3b can be easily inserted into the two hooks 9b. However, the flange 3b of this embodiment may be provided so as to surround the protruding portion 3a, similar to the flange 3b of the first embodiment. Also, as long as the magnet 3 is held by the magnet holder 9, the flange 3b may not be provided. The magnet holder 9 can firmly hold the flange 3b of the magnet 3 by using the hooks 9b.

[0048] In this embodiment, the magnet 3 held by the magnet holder 9 protrudes from the opening 4op to the front side and contacts the rear surface of the chassis 2. As with the display device 10 of the first embodiment, the display device 10 of this embodiment also has a small gap between the opening 4op and the protruding portion 3a. Therefore, relative positional deviation between the magnet 3 and the mounting member 4 is unlikely to occur.

[0049] The magnet holder 9 has a sleeve portion 9c. The sleeve portion 9c is provided along the short side of the rectangular cover portion 9a. The sleeve portion 9c is used to fix the magnet holder 9 to the mounting member 4. The sleeve portion 9c has a sleeve through hole 9cth. A male screw 5 is inserted into the sleeve through hole 9cth. The male screw 5 is screwed into the female screw hole 4sh of the mounting member 4, similar to the male screw 5 of the first embodiment. Therefore, the magnet holder 9 can be easily fixed to the mounting member 4.

[0050] The magnet holder 9 may be attached to the mounting member 4 by a fixing member such as a nail, a rivet, or a bolt instead of the male screw 5. The magnet holder 9 may also be fixed to the mounting member 4 by a method that does not use a fixing member, such as welding, adhesion, or bonding.

[0051] Also, the cover portion 9a of the magnet holder 9 covers the back surface of the magnet 3. This prevents the magnet 3 from being damaged by any impact being applied to the back surface of the magnet 3. Furthermore, since the magnet holder 9 is made of a non-magnetic material, the effect of the magnetic force of the magnet 3 on the components provided on the back surface side of the mounting member 4, such as the speaker 6, is reduced.

[0052] In this embodiment, the magnet holder 9 is screwed to the mounting member 4. Therefore, the magnet holder 9 is fixed to the mounting member 4. Therefore, the magnet holder 9 prevents the magnet 3 from coming off the mounting member 4. In this embodiment, the magnet holder 9 has a sleeve through hole 9cth, and the mounting member 4 has a female screw hole 4sh. However, the magnet holder 9 may have a female screw hole, and the mounting member 4 may have a through hole.

[0053] Generally, the magnet 3 has a low mechanical strength. Therefore, when a through hole is drilled in the magnet 3, there is a high possibility that damage will occur around the through hole of the magnet 3. However, according to the display device 10 of the present embodiment, since a through hole for inserting the male screw 5 is drilled in the magnet holder 9, there is no need to drill a through hole for inserting the male screw 5 in the magnet 3. Therefore, according to the display device 10 of the present embodiment, the possibility of damage to the magnet 3 is reduced compared to the case where a through hole is drilled in the magnet 3.

[0054] Furthermore, the magnet holder 9 has a sleeve portion 9c that protrudes along the back surface of the mounting member 4 from the cover portion 9a that covers the back surface of the magnet 3. The sleeve portion 9c is provided along the short side of the rectangular cover portion 9a.

[0055] Ribs 9c1 and 9c2 are provided on the surface of the sleeve portion 9c facing the mounting member 4. The ribs 9c1 and 9c2 are provided parallel to each other. A sleeve through hole 9cth is provided between the two ribs 9c1 and 9c2. The ribs 9c1 and 9c2 protrude from the sleeve portion 9c so as to abut against the chassis 2.

[0056] According to the ribs 9c1 and 9c2, a gap C (see Figs. 15 and 16) is formed between the surface of the sleeve portion 9c facing the mounting member 4 and the surface of the sleeve portion 9c facing the mounting member 4. This gap C ensures a space for the cylindrical protrusion in which the female screw hole 4sh of the mounting member 4 is formed, between the surface of the sleeve portion 9c facing the mounting member 4 and the surface of the sleeve portion 9c facing the mounting member 4.

[0057] In this embodiment, the hook portion 9b does not contact the mounting member 4, and only the tips of the ribs 9c1, 9c2 of the sleeve portion 9c contact the peripheral portion of the opening 4op. Therefore, friction between the magnet holder 9 and the mounting member 4 is reduced. Also, the protruding portion 3a of the magnet 3 protrudes from the opening 4op toward the chassis 2 and contacts the chassis 2. In this embodiment as well, the position of the magnet 3 relative to the mounting member 4 is fixed.

[0058] In the display device 10 of the present embodiment, the mounting member 4 has a female screw hole 4sh, similar to the display device 10 of the first embodiment. However, in the display device 10 of the present embodiment, unlike the display device 10 of the first embodiment, the male screw 5 is inserted into the sleeve through hole 9cth and screwed into the female screw hole 4sh.

[0059] In the display device 10 of the present embodiment, the position of the magnet 3 relative to the mounting member 4 can be fixed by the magnet holder 9. As a result, the display device 10 of the present embodiment can also suppress misalignment between the mounting member 4 and the magnet 3.

[0060] In the display device 10 of the present embodiment described above, similarly to the display device 10 of the first embodiment, the chassis 2 and the mounting member 4 are fixed in position relative to each other by the magnetic force between the magnetic body constituting the chassis 2 and the magnet 3 attached to the mounting member 4. Therefore, the chassis 2 and the mounting member 4 can be fixed in position only by the magnet 3 attached to the mounting member 4, without the need to attach any new parts to the chassis 2. Therefore, the number of parts can be reduced with the display device 10 of the present embodiment as well.

[0061] Also in the display device 10 of the present embodiment, the chassis 2 and the mounting member 4 are fixed in position only by the magnetic force between the magnetic body constituting the chassis 2 and the magnet 3 attached to the mounting member 4. Therefore, the positional relationship between the chassis 2 and the mounting member 4 can be easily fine-tuned.

[0062] (Embodiment 3) A display device 10 as an example of a device according to the second embodiment will be described with reference to Fig. 22 and Fig. 23. Note that, in the following, explanations of the same points as those of the display device 10 according to the first or second embodiment will not be repeated unless particularly necessary. The display device 10 according to the present embodiment differs from the display device 10 according to the first embodiment in the following points.

[0063] In the present embodiment, similarly to the first embodiment, the chassis 2 and the mounting member 4 are fixed in position relative to each other by the magnetic force between the magnetic material constituting the chassis 2 and the magnet 3 attached to the mounting member 4. Therefore, the chassis 2 and the mounting member 4 can be fixed in position only by the magnet 3 attached to the mounting member 4, without the need to attach any new parts to the chassis 2. Therefore, the display device 10 of the present embodiment can also reduce the number of parts.

[0064] Fig. 22 is a partially enlarged view of the mounting member 4 of the display device 10 of the present embodiment. Fig. 23 is a view for explaining the positioning structure between the chassis 2 and the mounting member 4 of the display device 10 of the present embodiment, and is a cross-sectional view taken along line XXIII-XXIII of Fig. 22.

[0065] 22 and 23, the chassis 2 and the mounting member 4 are positioned relative to each other by utilizing a positioning through hole 4pth provided in the mounting member 4 and a positioning protrusion 2pr provided in the chassis 2 and inserted into the positioning through hole 4pth. Instead of the positioning through hole 4pth, a positioning recess may be provided in the mounting member 4. This makes it possible to easily position the chassis 2 and the mounting member 4 in the manufacturing process of the display device 10.

[0066] The chassis 2 and the mounting member 4 may be positioned relative to each other by using a positioning protrusion provided on the mounting member 4 and a positioning through-hole (or a positioning recess) provided on the chassis 2 and into which the positioning protrusion is inserted. This also makes it possible to easily position the chassis 2 and the mounting member 4 in the manufacturing process of the display device 10.

[0067] In this embodiment, the positioning protrusion 2pr is a cylinder, and has a female screw portion 2sp on the inner surface of the cylinder. A cylindrical protrusion on the tip side, which has a diameter smaller than the diameter of the cylinder portion on the base side of the positioning protrusion 2pr, is inserted into the positioning through hole 4pth. In addition, a male screw 15 is screwed into the female screw portion 2sp. This makes it possible to prevent the positioning protrusion 2pr from coming out of the positioning through hole 4pth. The base of the positioning protrusion 2pr is fixed to the crimped through hole 2cth of the chassis 2 by the crimped portion CA.

[0068] In general, there are cases where a force parallel to the back surface of the chassis 2 is generated between the magnet 3 and the chassis 2, which cannot be resisted by the magnetic force between the magnet 3 and the magnetic material constituting the chassis 2 alone. Even in such cases, according to the display device 10 of the present embodiment, the engagement between the positioning protrusion 2pr and the positioning through hole 4pth can prevent misalignment between the chassis 2 and the mounting member 4.
