Hereinafter, a structure of the sandwich honeycomb panel and the pail nut 40 of the display apparatus 10 of the present invention will be described with reference to the drawings. The suffix "module" and " part "for the components used in the following description are given or mixed in consideration of ease of specification, and do not have their own meaning or role.

1 is a front perspective view of the display apparatus 10 of the present invention, and FIG. 2 is a rear perspective view of the display apparatus 10 of the present invention. The display apparatus 10 has a display module 20 and a case as main components.

The display panel 20 outputs an image on a screen, and may be modified in a predetermined range. The display panel 20 divides an image into a plurality of pixels and digitizes information such as color, brightness, and saturation for each pixel into an electrical signal, and controls to emit light according to the color, brightness, and saturation of the pixel according to the electrical signal. It is a device that outputs an image.

A flat panel display having a function of outputting such an image is various, such as a liquid crystal display, a thin film transistor liquid crystal display, a plasma display, an organic light-emitting diode (OLED) display, and the like in the present invention.

The case is coupled to the rear surface of the display module 20 to protect the display module, and to provide a control unit for supplying power to the display device 10 or controlling the display device 10.

Recently, as a device such as an organic light emitting diode is used, the display module 20 becomes thinner, and as consumers prefer the thinner display device 10, the case may cover the rear panel of the display module 20 only. And a control box in which various electronic components, controllers, and the like are mounted on the rear panel is used.

Such a structure has an advantage of reducing the size of the display apparatus 10, but the rigidity of the display apparatus 10 is determined by the thickness of the rear panel, so that the thickness of the rear panel cannot be reduced unconditionally. When the thickness of the rear panel is increased, the weight of the display apparatus 10 increases and the amount of material used for manufacturing the case increases, thereby increasing the case manufacturing cost.

Accordingly, the sandwich honeycomb panel 30 that can secure the rigidity and reduce the weight increase can be used for the back panel of the display apparatus 10. As shown in FIG. 3, the sandwich honeycomb panel 30 has a three-layer structure of a pair of thin plates 31 and 32 and a honeycomb structure 35 interposed therebetween.

The honeycomb structure 35 is characterized in that a plurality of hollow hexagonal columnar unit structures 35a are gathered to form a honeycomb structure. Since the side surface of a hexagonal column and the plane (surface of a thin plate) of the sandwich honeycomb panel 30 are mutually orthogonal to each other, rigidity is large with respect to the force of all directions. Therefore, there is an advantage that the rigidity is greater than the previous back panel composed of one single member.

A sandwich honeycomb panel 30 having a thickness of about 3 mm can be used by using a pair of thin plates 31 and 32 having a thickness of 0.2 mm and a honeycomb structure 35 having a thickness of 2.6 mm used in the display device 10 of the present invention. have. By using the sandwich honeycomb panel 30 having the thickness, the display module 20 may be protected from an external impact and a case which is not easily deformed may be provided.

As shown in FIG. 2, the display device 10 having a control box separately needs to insert a fem nut 40 for fixing the control box to a case. Pam nut 40 is a structure having a screw insertion portion 42 corresponding to the shape of the screw 44 so that the screw 44 can be inserted, one side of the member when the two members are combined with the screw 44 Is inserted into

In order to support the force of the inserted pem nut 40, the inserted member is required to have a thickness of about 0.8 mm or more. However, since the thickness of the thin plates 31 and 32 of the sandwich honeycomb panel 30 described above is only 0.2 mm, it is difficult for the fem nut 40 to be fixed.

Thus, the pail nut 40 of the present invention is characterized in that it has a structure that can be easily inserted into the structure of the sandwich honeycomb panel 30 and can be stably fixed at the time of insertion. 4 illustrates a cross-sectional view of a display apparatus according to an exemplary embodiment, in which a sandwich honeycomb panel 30 coupled to a rear surface of the display module 20 is illustrated.

The Pam nut 40 of the present invention includes a Pam nut body 41 having a screw insertion part 42 formed on one side thereof and is inserted into the sandwich sandwich panel 30 such that the screw insertion part 42 is exposed on the rear surface of the sandwich sandwich honeycomb panel 30. [ .

As shown in FIG. 4, the pail nut body 41 of the display apparatus 10 of the present invention is inserted into the unit structure 35a of the sandwich honeycomb panel 30 as shown in FIG. 4. That is, the circumferential shape of the pail nut 40 corresponds to the shape of the unit tissue 35a so that the circumference of the pail nut body 41 can be inserted into the unit structure 35a of the sandwich honeycomb panel 30. do.

As described above, since the unit structure 35a has a hollow hexagonal column shape, the fem nut body 41 has a size of a fem nut 40 that can be inserted into the unit tissue 35a as shown in FIG. 5. It is a pillar.

Since the honeycomb structure 35 is strong to the force in the direction perpendicular to the thickness, the weight of the control box, etc., when the Pam nut 40 inserted into the unit structure 35a is combined with the screw 44 fixing the control box. I can support it.

In order to be more stably fixed, the adhesive is applied to the circumference of the fem nut body 41 and inserted, or as shown in FIG. 4, the other ends of the front thin plate 31 and the fem nut body 41 which contact the display panel are screwed ( It can be fixed by tightening with 44).

That is, the opening 34 is formed so that one unit structure 35a is exposed at the position where the fem nut 40 is to be inserted into the rear thin plate 32 of the sandwich honeycomb panel 30. The rear thin plate 32 having the opening 34 for inserting the Pam nut 40 at the position where the Pam nut 40 is inserted in advance is combined with the honeycomb structure 35 to manufacture the sandwich honeycomb panel 30 It is possible.

The adhesive is applied to the pamp nut body 41 to be inserted into the honeycomb unit tissue 35a exposed on the back of the sandwich honeycomb panel 30 or to penetrate the front thin plate 31 to be inserted into the other end of the pampnut body 41. It can be fixed using (44). Thereafter, as shown in FIG. 4, the sandwich honeycomb panel 30 is coupled using the display module 20 and the double-sided tape.

FIG. 6 illustrates another embodiment of the present invention, in which the pamp nut 40 used in the embodiment of FIG. 6 includes a pamp nut head 43. The Pam nut head 43 is a plate member which is coupled to the other end of the screw 44 insertion opening, that is, the other end of the Pam nut body 41 and is larger than the diameter of the Pam nut body 41. As shown in FIG. 6, the pumnut head 43 is positioned on the same plane as the outer side of the honeycomb tissue 35 and the front thin plate 31 to fix the position of the pumnut body 41.

The hexagonal pillar of the nut nut body 41 may be inserted into the unit structure 35a to stably fix the fem nut 40, but the shape of the fem nut head 43 may also be more stable if it is polygonal than circular. Can be fixed In particular, by making the shape of the pem nut head 43 into a hexagonal shape as shown in FIG. 7, the force applied to the pem nut can be evenly distributed.

In order to prevent the honeycomb panel 30 and the display module 20 from being lifted up, as shown in FIG. 6, the thickness of the head of the fem nut 40 preferably corresponds to the thickness of the front plate 31. .

If the nut nut head 43 is thin, it is difficult to make it integral as shown in FIG. 7, and thus, the fem nut head 43 and the pem nut body 41 may be manufactured separately and combined with screws 44 as shown in FIG. 8. have.

When inserting the fem nut 40 with the fem nut head 43, openings 33 and 34 should be formed in both the front thin plate 31 and the rear thin plate 32 as shown in FIGS. . An opening 34 having a size corresponding to the cross section of the Pam nut body 41 is formed in the case of the front thin plate 31 and the opening 33 corresponding to the Pam nut head 43 in the case of the rear thin plate 32 do.

After the insertion of the Pam nut 40, the front surface of the Pam nut body 41 is flush with the Pam nut head 43 on the same plane as the front thin plate 31, The insertion portion 42 is visible.

The pem nut body 41 may be formed to have the same thickness as the sandwich honeycomb panel 30, but may protrude as shown in FIG. 10. The protrusion of the Pam nut body 41 on the rear surface may vary depending on the thickness of the screw insertion portion 42 or the thickness of the sandwich honeycomb panel 30.

10, when the pumnut body 41 protrudes from the rear plate 32 as shown in FIG. 10, the washer can be stably fixed by combining the washers. The washer is a plate-shaped member having a hole corresponding to the cross section of the Pam nut body 41. The Pam nut body 41 can be inserted into the hole and coupled to the rear face plate 32 with a double-sided tape or the like. The washer prevents the inserted Pam nuts (40) from moving and fixes the sandwich honeycomb panel (30) more stably.

11 is a cross-sectional view of a display device 10 according to another embodiment of the present invention. The Pam nuts (40) of the present invention can use the circular nuts (40) which are conventionally used. A hole larger than the thickness of the Pam nut body 41 is formed and the hole 36 is filled with the resin to fix the Pam nut 40. [

The honeycomb structure of the sandwich honeycomb panel 30 and the rear panel are cut to form the insertion part of the Pam nut 40 and the Pam nut 40 is inserted so that the part of the screw 44 of the Pam nut 40 is exposed, It may be filled. Alternatively, the resin 36 may be filled and hardened in the insertion portion of the Pam nut 40 formed by cutting the sandwich honeycomb panel 30, and then a hole corresponding to the cross section of the Pam nut 40 may be formed, 40 may be inserted.

This method is advantageous in that the fixing force can be reinforced by the resin 36 and the conventional Pam nuts 40 can be used, so that there is no need to manufacture the Pam nuts 40 separately.

The sandwich honeycomb panel 30 has a problem in that the honeycomb structure 35 is exposed in the cross section, and if the honeycomb structure 35 is exposed to the exterior, it should cover it. However, since the thickness of the sandwich honeycomb panel 30 is thin, it is difficult to couple the finishing member 38 covering the side circumference to the sandwich honeycomb panel 30.

Accordingly, as shown in FIG. 12, one of the thin plates 31 and 32 positioned on both sides of the sandwich honeycomb panel 30 is formed larger than the honeycomb tissue 35 to be protruded, and then the protruding thin plate portion 31a is bent. The honeycomb structure 35 exposed on the cross section of the sandwich honeycomb panel 30 may be covered.

Alternatively, as shown in FIG. 13, the finishing member 38 may be coupled to both the protruding portion 31b and the side surfaces of the honeycomb tissue 35 by using a thin plate protruding around the honeycomb tissue 35. Therefore, it can be attached easily compared with the case where it couples only to the side surface of the honeycomb structure | structure 35. FIG.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
