[0049] See also Figure 1 An embodiment of the present application provides a housing assembly 10, comprising a connected housing cover 12 and a housing bracket 11, wherein the housing bracket 11 is formed by splicing a plurality of bracket units.

[0050] It should be noted that, in the embodiments of the present application, a plurality refers to two or more, for example, three, four, five, six, seven, eight, nine, ten, etc.

[0051] Exemplarily, each of the bracket units is provided with a plurality of hollow patterns 80, which can reduce the weight of the shell bracket 11, thereby reducing the weight of the shell assembly 10 and reducing the production cost of the shell assembly 10; the embodiment of the present application adopts a combination of a shell cover 12 (extruded board) and a shell bracket 11, so that the shell assembly 10 can be made thinner and more beautiful in appearance.

[0052] Illustratively, the housing assembly 10 may be used as a rear case of a display device.

[0053] For example, the shell cover 12 is an extruded board, and the board only needs to be extruded into a mold, so the mold cost is low, the extruded board is thin, has few appearance defects, stable performance, and easy size control.

[0054] The shell assembly 10 provided in the embodiment of the present application includes a connected shell cover 12 and a shell bracket 11, so that the shell bracket 11 can be used to support the shell cover 12, thereby making the shell assembly 10 have higher mechanical strength. Since the shell bracket 11 is made of a plurality of bracket units, each bracket unit is prepared using a smaller mold. In the prior art, the shell bracket is usually an integrated structure and is prepared by an injection molding process. Since the area of the shell bracket is large and the structures of each area are different, the mold area used for the injection-molded shell bracket is large and the structure is complex, which makes the mold production cost high, thereby resulting in a high production cost of the shell bracket. The embodiment of the present application is achieved by The shell bracket 11 is decomposed into multiple bracket units. Since the area of a single bracket unit is small and the structure is relatively simple, a mold with a small area and a relatively simple structure can be used when injecting a single bracket unit, thereby reducing the production cost of the mold. Moreover, compared with the method of injecting the shell bracket as a whole, the injection molding yield of the small bracket unit is higher, thereby reducing the production cost of the shell bracket 11. Moreover, multiple bracket units can be injection molded using the same mold. After the injection molding is completed, bracket units with different structures can be obtained by appropriately cutting the obtained injection molded body. Therefore, the present application can greatly reduce the production cost of the shell bracket 11, and thereby reduce the production cost of the shell assembly 10.

[0055] Exemplarily, the housing bracket 11 and the housing cover 12 are connected by glue or double-sided tape.

[0056] See also Figure 1 and Figure 2 The housing bracket 11 includes a first bracket unit 51 and a second bracket unit 52 and a third bracket unit 53 respectively located on both sides of the first bracket unit 51, and the second bracket unit 52 and the third bracket unit 53 are both connected to the first bracket unit 51;

[0057] A first opening area 521 is provided on a side of the second bracket unit 52 facing away from the first bracket unit 51;

[0058] A second opening area 531 is defined on a side of the third bracket unit 53 facing away from the first bracket unit 51 .

[0059] Exemplarily, a plurality of hollow patterns 80 are provided on each of the first bracket unit 51 , the second bracket unit 52 and the third bracket unit 53 .

[0060] Exemplarily, the first bracket unit 51, the second bracket unit 52 and the third bracket unit 53 are all prepared by injection molding and using the same mold. The second bracket unit 52 is cut to form the first opening area 521 after injection molding, and the third bracket unit 53 is cut to form the second opening area 531 after injection molding.

[0061] See also Figure 4 and Figure 5 It can be seen that the second bracket unit 52 and the third bracket unit 53 can be obtained respectively on the basis of the first bracket unit 51 by cutting the weak connection position 90 on the first bracket unit 51. Since the first bracket unit 51, the second bracket unit 52 and the third bracket unit 53 are prepared using the same mold, the mold cost and injection molding cost are low, thereby reducing the production cost of the shell bracket 11. Compared with the technical solution of using a set of large-sized molds to obtain the shell bracket 11 by injection molding in one go, this proposal prepares three small brackets and splices them to obtain a large-sized shell bracket 11. Only one set of small molds is needed, the mold cost is low, the injection molding difficulty is low, and the small brackets serve as internal reinforcements. There are no appearance requirements, the size and deformation are easy to control, and the injection molding yield is high.

[0062] See also Figure 1 and Figure 2The shell assembly 10 also includes a power terminal bracket 61, which is used to fix the power terminal (AC terminal). The power terminal bracket 61 is located in the first opening area 521 of the second bracket unit 52, and the power terminal bracket 61 is connected to the shell cover 12.

[0063] Exemplarily, the housing cover 12 is provided with an opening corresponding to the power terminal bracket 61 to expose the power terminal (AC terminal).

[0064] See also Figure 1 and Figure 2 The shell assembly 10 also includes a video interface terminal bracket 62, which is used to fix the video interface terminal (AV terminal). The power terminal bracket 61 is located in the first opening area 521 of the second bracket unit 52, and the video interface terminal bracket 62 is connected to the shell cover 12.

[0065] Exemplarily, the housing cover 12 is provided with an opening corresponding to the video interface terminal bracket 62 to expose the video interface terminal (AV terminal).

[0066] It should be noted that since the power terminal bracket 61 and the video interface terminal bracket 62 have a special structure and a small size, the power terminal bracket 61 and the video interface terminal bracket 62 are respectively made using smaller molds. Compared with the method of preparing the power terminal bracket 61 and the video interface terminal bracket 62 and the shell bracket 11 in the same injection molding process, the production cost can be more effectively reduced.

[0067] Exemplarily, the power terminal bracket 61 is connected to the housing cover 12 by glue or double-sided tape.

[0068] Exemplarily, the video interface terminal bracket 62 is connected to the housing cover 12 by glue or double-sided tape.

[0069] See also Figure 1 、 Figure 2 and Figure 3 The shell bracket 11 further includes a first connecting member 71 and a second connecting member 72 , wherein the first connecting member 71 is used to connect the first bracket unit 51 and the second bracket unit 52 , and the second connecting member 72 is used to connect the first bracket unit 51 and the third bracket unit 53 .

[0070] Exemplarily, the first connecting member 71 and the second connecting member 72 have the same structure.

[0071] Exemplarily, the first connecting member 71 is connected to the first bracket unit 51 via screws, and the first connecting member 71 is connected to the second bracket unit 52 via screws.

[0072] Exemplarily, the first connecting member 71 is square, and the two opposite sides of the first connecting member 71 are respectively connected and fixed to the first bracket unit 51 and the second bracket unit 52. Circular holes are provided on both sides of the first connecting member 71, and screw holes corresponding to the circular holes are provided on the first bracket unit 51 and the second bracket unit 52 to facilitate bolt fixing. A protrusion is provided on the first connecting member 71 corresponding to the connection seam position of the first bracket unit 51 and the second bracket unit 52 (that is, the center of the first connecting member 71) to avoid the edges of the first bracket unit 51 and the second bracket unit 52 when connecting the first bracket unit 51 and the second bracket unit 52.

[0073] Exemplarily, the second connecting member 72 is connected to the first bracket unit 51 via screws, and the second connecting member 72 is connected to the third bracket unit 53 via screws.

[0074] See also Figure 2 The second connecting member 72 is square, and the two opposite sides of the second connecting member 72 are respectively connected and fixed to the first bracket unit 51 and the third bracket unit 53. Circular holes are provided on both sides of the second connecting member 72, and screw holes corresponding to the circular holes are provided on the first bracket unit 51 and the third bracket unit 53 to facilitate bolt fixing. A protrusion is provided on the second connecting member 72 corresponding to the connection seam position of the first bracket unit 51 and the third bracket unit 53 (that is, the center of the second connecting member 72) to avoid the edges of the first bracket unit 51 and the third bracket unit 53 when connecting the first bracket unit 51 and the third bracket unit 53.

[0075] See also Figure 6 , an embodiment of the present application provides a display device 100, including the housing assembly 10 as described above.

[0076] See also Figure 6 The housing assembly 10 may be a rear housing of the display device 100 .

[0077] Exemplarily, a gap is provided between the back plate 30 and the display panel 40 , and an optical film group and a light source are provided in the gap. Light emitted by the light source passes through the optical film group and displays image information on the display panel 40 .

[0078] Exemplarily, the display device 100 can be a terminal such as a television, a mobile phone, or a tablet computer, and can also be a gaming device, an augmented reality (AR) device, a virtual reality (VR) device, a data storage device, an audio playback device, a video playback device, a wearable device, or other device with a display screen, where the wearable device can be a smart bracelet, smart glasses, a smart watch, smart decoration, etc.

[0079] See also Figure 7 The display device further includes an elastic buckle 20 and a back plate 30, wherein the elastic buckle 20 is disposed between the housing assembly 10 and the back plate 30, and both the housing assembly 10 and the back plate 30 are connected to the elastic buckle 20;

[0080] A first engaging groove 151 is defined on the inner side of the housing assembly 10 . The elastic buckle 20 includes a first engaging portion 23 , and the first engaging portion 23 is engaged with the first engaging groove 151 .

[0081] The display device 100 provided in the embodiment of the present application uses an elastic clip 20 to connect the back panel 30 and the shell assembly 10. A first locking groove 151 is provided on the inner side of the shell assembly 10, and the first locking groove 151 is locked and connected with the first locking portion 23 of the elastic clip 20. Since the elastic clip 20 is easy to deform when under pressure, when repairing the display device 100, the elastic clip 20 can be easily separated from the shell assembly 10, thereby realizing the separation of the shell assembly 10 and the back panel 30. The shell assembly 10 is not easily damaged during the disassembly process, thereby improving the maintainability of the display device 100. In addition, since the first locking groove 151 on the shell assembly 10 is located on the inner side of the first plate body 111, the outer surface of the shell assembly 10 is flat and smooth, and there is no need to set destructive structures such as screw slots and connection holes, thereby improving the appearance of the shell assembly 10, and thus improving the appearance of the display device.

[0082] It is understandable that since the elastic clip 20 is connected to the shell assembly 10 by a snap connection, when the elastic clip 20 is damaged, only the elastic clip 20 needs to be replaced without replacing the entire shell assembly 10, and the maintenance cost is low.

[0083] See also Figure 7 、 Figure 8 、 Figure 9 and Figure 10The shell bracket 11 is arranged toward the back plate 30, and the shell bracket 11 includes a first plate body 111 and a first protrusion 112. The first protrusion 112 is connected to the first plate body 111 and protrudes toward the direction close to the back plate 30. The inner surface of the first protrusion 112 and the shell cover 12 enclose a first engaging groove 151. The first protrusion 112 is provided with a first through hole 141, and the first through hole 141 is connected to the first engaging groove 151.

[0084] It can be understood that since the shell cover 12 is located on the outside of the first snap-fit groove 151, the user cannot see the first snap-fit groove 151 from the outside. At this time, the outer surface of the shell cover 12 is the outer surface of the shell assembly 10. Since the outer surface of the shell cover 12 is flat, the outer surface of the shell assembly 10 seen by the user is flat, which can improve the overall appearance of the display device 100.

[0085] See also Figure 7 、 Figure 10 and Figure 15 The elastic clip 20 also includes a clip body 21 and a first connecting portion 22, the two ends of the first connecting portion 22 are respectively connected to the clip body 21 and the first locking portion 23, the first connecting portion 22 passes through the first through hole 141, and the first locking portion 23 is arranged in the first locking groove 151. The orthographic projection of the first locking portion 23 on the plane where the first plate body 111 is located and the orthographic projection of the clip body 21 on the plane where the first plate body 111 is located are both larger than the orthographic projection of the first through hole 141 on the plane where the first plate body 111 is located.

[0086] See also Figure 7 、 Figure 10 and Figure 15 A gap is provided between the first connecting portion 22 of the elastic clip 20 and the hole wall of the first through hole 141 , and a gap is provided between the first engaging portion 23 of the elastic clip 20 and the groove wall of the first engaging groove 151 .

[0087] It should be noted that, by designing a gap between the first connecting portion 22 of the elastic clip 20 and the hole wall of the first through hole 141, and a gap between the first engaging portion 23 of the elastic clip 20 and the groove wall of the first engaging groove 151, the elastic clip 20 can move in the first through hole 141 and the first engaging groove 151. When the elastic clip 20 is engaged with the back plate 30 and the position of the second engaging portion 25 of the elastic clip 20 in the second engaging groove 306 of the back plate 30 is displaced, since the elastic clip 20 itself is elastic and the elastic clip 20 can move relatively in the first through hole 141 and the first engaging groove 151, the elastic clip 20 can use its own elasticity to perform self-correction, so that the position of the second engaging portion 25 of the elastic clip 20 in the second engaging groove 306 of the back plate 30 is restored to the preset position.

[0088] Exemplarily, the first connecting portion 22 is cylindrical, that is, the cross-section of the first connecting portion 22 is circular, the first through hole 141 is a circular hole, and the diameter of the first through hole 141 is slightly larger than the diameter of the cross-section of the first connecting portion 22, so that a gap is maintained between the first connecting portion 22 of the elastic clip 20 and the hole wall of the first through hole 141.

[0089] Exemplarily, the first engaging groove 151 and the first engaging portion 23 are both cylindrical, that is, the cross-section of the first engaging groove 151 and the first engaging portion 23 are each circular, and the diameter of the cross-section of the first engaging groove 151 is slightly larger than the diameter of the cross-section of the first engaging portion 23, so that a gap is maintained between the first engaging portion 23 of the elastic clip 20 and the groove wall of the first engaging groove 151.

[0090] See also Figure 12 The first side plate 120 has a first opening 121, which is connected to the first engaging groove 151. The first top plate 130 has a second opening 132, which is connected to the first through hole 141, so that the first engaging portion 23 passes through the first opening 121 into the first engaging groove 151, and the first connecting portion 22 passes through the second opening 132 into the first through hole 141.

[0091] Exemplarily, a guide angle is designed at the second opening 132 so that the first connecting portion 22 of the elastic buckle 20 can more easily pass through the second opening 132 and enter the first through hole 141 .

[0092] See also Figure 12 The first through hole 141 is a circular hole, and the width of the second opening 132 is smaller than the diameter of the first through hole 141 .

[0093] See also Figure 12 The housing assembly 10 is further provided with a guide groove 125 , which is communicated with the first opening 121 and the first engaging groove 151 , so that the elastic buckle 20 is guided to the first opening 121 via the guide groove 125 .

[0094] See also Figure 12 A guide hole is provided on the housing bracket 11 , and the hole wall of the guide hole and the housing cover 12 together enclose the guide groove 125 .

[0095] See also Figure 11 and Figure 12 , while combining Figure 11 and Figure 12 The installation process of the elastic clip 20 and the housing assembly 10 is as follows: first, place the elastic clip 20 in the guide groove 125, then move the elastic clip 20 so that the first engaging portion 23 of the elastic clip 20 passes through the first opening 121 and enters the first engaging groove 151, and the first connecting portion 22 of the elastic clip 20 passes through the second opening 132 and enters the first through hole 141. It should be noted that Figure 11 The arrow in the figure is used to indicate the moving direction of the elastic buckle 20 during the installation process.

[0096] See also Figure 7 and Figure 14 A second locking groove 306 is provided on the back panel 30, and the elastic clip 20 also includes a clip body 21 and a second locking portion 25. The first locking portion 23 and the second locking portion 25 are respectively provided on both sides of the clip body 21 and are both connected to the clip body 21.
