The side plate 202 is opposite to the side of the outer side plate 11 facing the extension plate 12, and the side plate 202 is connected to the outer side plate 11 to fix the middle frame 1 and the back plate 2. The end of the side plate 202 remote from the bottom plate 201 is located in the gap 3. The first folding plate 13, the side plate 202 and the bottom plate 201 form a first receiving space 10 b. The first receiving space 10b is a second sub-cavity.

The backlight assembly 20 is disposed on the bottom plate 201. An edge portion of the backlight assembly 20 is disposed in the first receiving space 10 b. Specifically, the backlight assembly 20 is interposed between the extension plate 12 and the bottom plate 201, so that the backlight assembly 20 is fixed relative to the case assembly 10 in the Z-axis direction.

The display assembly 30 is disposed on a side of the backlight assembly 20 facing away from the bottom plate 201. The edge portion of the display module 30 is disposed on the extension plate 12.

The present application provides a housing assembly 10 and a display device 100, which are formed by structurally designing a middle frame 1 and a rear plate 2, so that the middle frame 1 and the back plate 2 surround and form a semi-open first accommodating space 10b for accommodating the assembly parts, since the first accommodating space 10b is formed by assembling the middle frame 1 and the back plate 2, in the assembling process, the back plate 2 can be mounted to the middle frame 1 together with the assembly after the assembly is mounted to the back plate 2, the housing assembly 10 provided by the present application has a structure that improves the formation of the first housing space 10b, so that the assembly parts are more simple and convenient to install, and the assembly parts are not warped or damaged by friction, namely, the mounting convenience of the assembly parts of the display apparatus 100 is improved, the assembly parts of the display apparatus 100 can be effectively prevented from being damaged, and the assembly yield of the display apparatus 100 is improved.

In the display device 100 of the general technology, the top end of the back plate 2 of the display device 100 is bent and extended toward the inner cavity of the back plate 2 to form a limiting cavity for accommodating and limiting the backlight assembly 20 in the Z-axis direction. The middle frame 1 and the back plate 2 are adhered by adhesive tapes.

However, in the general technology, the inside of the spacing cavity formed by the back plate of the display device gap needs to be attached with a buffer pressing piece for preventing the light guide plate and the optical film in the backlight assembly from being damaged during assembly, and the distance between the attachment surface of the buffer pressing piece and the bearing surface of the reflector plate is small, so that the attachment operation of the buffer pressing piece is not easy, and the production efficiency of the display device gap is affected; because the backboard forms a limiting cavity in the Z-axis direction, the optical diaphragm, the light guide plate and the reflector plate need drawer type assembly, the light guide plate allows the bending bow to warp and does not exceed 1.5mm, the optical diaphragm allows the warping which does not exceed 1.5mm and does not exceed a wave, and in the backboard thinning design process, the gap between the optical diaphragm and the bottom of the backboard is generally 0.5-0.8 mm. If light guide plate and optics diaphragm self deformation exceed with the backplate between the clearance, when equipment light guide plate and optics diaphragm, the distortion or the displacement phenomenon that the slow-witted closing leads to because of the side atress easily appear to the foreign matter that produces because of the cotton scratch of bubble in the backlight unit appears, because of the cotton deformation of bubble or the poor scheduling problem in backlight unit bright border that the displacement leads to. In addition, because the back plate and the middle frame in the general technology are fixed by tape bonding, the tape bonding position is hidden, so that the back plate and the middle frame are difficult to detach and have no reworkability. And when the single back plate without the middle frame or the single middle frame without the back plate has poor appearance, the shell assembly is easily scrapped.

Based on the above problems, the housing assembly 10 provided in the embodiment of the present application can be applied to the display device 100 with a narrow frame, and the middle frame 1 and the back plate 2 surround and form the semi-open first accommodating space 10b, so that the problems that the attachment operation of the buffering pressing piece is not easy, and the light guide plate 23 and the optical film 24 are not good due to the assembly of the drawer are effectively solved. The side plate 202 of the back plate 2 is connected with the outer side plate 11 of the middle frame 1, so that the problem of cost increase caused by scrapping of parts due to poor assembly adhesion of the back plate 2 and the middle frame 1 is solved to the greatest extent.

In this application, the outer panel 11, the extension panel 12 and the first folding panel 13 are integrally formed by bending a plate. Specifically, the material of the middle frame 1 is not specifically described in the present application, for example, the material of the middle frame 1 includes, but is not limited to, plastic, metal, ceramic, and the like. In this embodiment, the middle frame 1 is made of metal, such as aluminum, alloy, sheet metal, and stainless steel. The middle frame 1 can be integrally formed by rolling. The outer side plate 11, the extension plate 12 and the first folding plate 13 are integrally formed by bending one plate, so that the cross section of the middle frame 1 is small, and foreign matters generated by friction between the backlight assembly 20, the display assembly 30, the back plate 2 and the middle frame 1 in the assembling process are reduced, thereby affecting the display effect of the display device 100.

The first folding plate 13 and the extension plate 12 are formed by reversely bending the plate, so that the cut surface of the plate is R-processed (i.e. reversely bent) in the rolling process, and thus, the joint of the first folding plate 13 and the extension plate 12 is an arc-shaped end portion, thereby effectively avoiding the occurrence of metal foreign matters caused by friction between the cut surface and the back plate 2 in the assembling process, and preventing the display module 30 and the backlight module 20 from being scratched.

The first folding plate 13 and the extension plate 12 are designed in an R shape, and have a certain guiding effect to facilitate the engagement of the middle frame 1 and the back plate 2, thereby effectively preventing the generation of foreign matters during the assembly and engagement process.

Referring to fig. 6, 7 and 9, one end of the outer panel 11 extends out of the side of the extension panel 12 facing away from the first folding back panel 13. In other words, the orthographic projection of extension plate 12 on outer plate 11 is located on outer plate 11. The second receiving space 10c is formed by half-surrounding the extension plate 12 and a portion of the outer plate 11. The second receiving space 10c is for receiving at least a portion of the display module 30.

Specifically, the extension plate 12 divides the inner cavity of the housing assembly 10 into a first receiving space 10b and a second receiving space 10 c. The first receiving space 10b is used for receiving the backlight assembly 20, and the second receiving space 10c is used for receiving the display assembly 30, so that the backlight assembly 20 and the display assembly 30 can be installed in different areas. Meanwhile, since the extension plate 12, i.e., the press-fit backlight assembly 20, also supports the display assembly 30, a glue layer and/or a foam layer may be disposed on both sides of the extension plate 12 in the Z-axis direction to bond the display assembly 30 and the backlight assembly 20.

Compared with the structure that the glue layer and/or the foam layer are arranged on one side, facing the bottom, of the bent extension plate 12 at the top of the back plate 2 in the general technology, the operation difficulty of arranging the glue layer and/or the foam layer on the two sides of the extension plate 12 is greatly reduced, so that the assembly difficulty of the display device 100 can be greatly reduced, and the assembly convenience of the display device 100 is improved; the back plate 2 does not form a limiting cavity in the Z-axis direction of the backlight assembly 20, so that the problems of damage, foreign matter generation and the like of the light guide plate 23 and the optical film 24 of the backlight assembly 20 during assembly can be reduced, and the assembly yield of the display device 100 is improved.

Referring to fig. 6, 7 and 9, the middle frame 1 further includes a second folding plate 14. The second flap 14 is located at an end of the extension panel 12 facing away from the first flap 13. One end of the second flap 14 is connected to the outer panel 11 away from the first end. The second flap 14 is attached to or opposes the first portion of the outer panel 11. The second folded plate 14 and the outer side plate 11 are formed by reversely bending the plate, so that the cut surface of the plate is subjected to R treatment in the rolling process, and thus, the joint of the second folded plate 14 and the outer side plate 11 is an arc-shaped end part, thereby effectively avoiding metal foreign matters caused by friction between the cut surface and the back plate 2 in the assembling process, and preventing the display assembly 30, the backlight assembly 20 and the like from being scratched.

The length direction of the second folded plate 14 is the X-axis direction, and the width direction of the second folded plate 14 is the Z-axis direction. In this embodiment, the second flap 14 is attached to the outer panel 11.

The other end of the second flap 14 is connected to one end of the extension panel 12. The second folding plate 14 and the extension plate 12 enclose the second receiving space 10 c.

In this embodiment, the plate extending along the positive direction of the Z axis is bent in a reverse direction to form the outer plate 11 and the second folding plate 14, and then bent in the positive direction of the Y axis to form the extending plate 12, and then the plate is bent in the reverse direction of the Y axis to form the first folding plate 13.

Referring to fig. 6, 7 and 9, the middle frame 1 further includes a third folding plate 15. One end of the third flap 15 is connected to an end of the outer panel 11 remote from the second flap 14. The third flap 15 is attached to or opposite the outer panel 11. The other end of the third flap 15 extends into the gap 3.

The third folded plate 15 and the outer side plate 11 are formed after the plate is reversely folded and pressed, so that in the rolling process, the cut surface of the plate is subjected to R treatment, and thus, the joint of the third folded plate 15 and the outer side plate 11 is an arc-shaped end part, thereby effectively avoiding metal foreign matters caused by friction between the cut surface and the back plate 2 in the assembling process, and preventing the display assembly 30, the backlight assembly 20 and the like from being scratched. The third folding plate 15 and the second folding plate 14 can also reinforce the strength of the outer panel 11 to increase the strength of the bezel of the display device 100.

The third flap 15 is spaced apart from the second flap 14. The end of the third flap 15 not connected to the outer panel 11 is disposed in the gap 3, and the end of the third flap 15 not connected to the outer panel 11 is spaced apart from the end of the first flap 13 not connected to the extension panel 12. The side panel 202 extends between the end of the third flap panel 15 not connected to the outer panel 11 and the end of the first flap panel 13 not connected to the extension panel 12.

Referring to fig. 10 and 11, the third folding plate 15 is disposed between the outer side plate 11 and the side plate 202 of the back plate 2, and one side of the third folding plate 15 facing the side plate 202 is provided with at least one first fastening portion 151. The side panel 202 is provided with at least one second snap-fit portion 221. The second fastening portion 221 is fastened to the first fastening portion 151.

The second fastening portion 221 is disposed in the first fastening portion 151, and a bottom of the second fastening portion 221 abuts against a bottom of the groove of the first fastening portion 151, so that the middle frame 1 and the back plate 2 are positioned in the opposite direction of the Z axis. The first fastening portion 151 is disposed on the third folded plate 15, so that a groove is effectively prevented from being formed on the outer side plate 11 to damage the appearance of the outer side plate 11.

In other embodiments, the first fastening portion 151 is a convex hull, and the second fastening portion 221 is a concave trough. In this embodiment, the first fastening portion 151 may be disposed on the side of the outer panel 11 facing the side panel 202 of the backboard 2, and the third folding plate 15 is not required, so as to reduce the frame width.

Further, referring to fig. 14, the end surface of the side plate 202 not connected to the end of the bottom plate 201 is provided with a buffer 41, and the buffer 41 has a certain amount of elastic compression deformation. In the assembling process, the side plate 202 extends into the gap 3 and compresses the buffer 41 together with the extension plate 12, the buffer 41 is compressed, the bottom of the second buckling part 221 on the side plate 202 is abutted against the bottom of the groove of the first buckling part 151, the buffer 41 restores to be partially deformed, the buffer 41 is abutted against the end parts of the extension plate 12 and the side plate 202 in the Z-axis direction, and the bottom of the second buckling part 221 is abutted against the bottom of the groove of the first buckling part 151, so that the backboard 2 and the middle frame 1 are stably assembled in the Z-axis direction.

The buffer 41 includes, but is not limited to, a spring plate, elastic silicone, foam, etc.

The number of the first fastening portions 151 of the third folding plate 15 is plural, and the number of the second fastening portions 221 of the side plate 202 is plural. The first fastening portions 151 are fastened to the second fastening portions 221 in a one-to-one correspondence manner. Thus, the connection stability of the middle frame 1 and the back plate 2 is increased.
