Description

Housing assembly and display device

[0001] This application claims priority to Chinese Patent Application No. 202421814337.1, filed on July 29, 2024, entitled "Housing Assembly and Display Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of display technology, and in particular to a housing assembly and a display device. Background Technology

[0003] A television set is a device that uses electronic technology to transmit moving images and audio signals based on the persistence of vision and visual psychology of the human eye. It is also an important tool for broadcasting and video communication. Technical issues

[0004] The back cover of a television is located at the back of the television. Its main function is to protect the internal components of the television and to connect other devices and external interfaces. The back cover of a television is usually composed of a back cover plate and a back cover bracket. In related technologies, the back cover bracket is usually a one-piece structure and is manufactured by injection molding. However, due to the large area of ​​the back cover bracket and the different structures of each area, the mold area used for injection molding the back cover bracket is large and the structure is complex, which leads to high mold manufacturing costs, resulting in high manufacturing costs for the back cover bracket. Technical solutions

[0005] Based on this, embodiments of this application provide a housing assembly and a display device.

[0006] In a first aspect, embodiments of this application provide a housing assembly, including a connected housing cover and a housing support, wherein the housing support is assembled from multiple support units.

[0007] Secondly, embodiments of this application provide a display device including the housing assembly described above. Beneficial effects

[0008] The housing assembly provided in this application includes a connected housing cover plate and a housing bracket, which can support the housing cover plate, thereby giving the housing assembly high mechanical strength. This application decomposes the housing bracket 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 injection molding a single bracket unit, thereby reducing the mold manufacturing cost. Moreover, compared with the method of injection molding the entire housing bracket, the injection molding yield of small bracket units is higher, and multiple bracket units can be injection molded using the same mold. After injection molding, bracket units with different structures can be obtained by appropriately cutting the injection molded body. Therefore, this application can greatly reduce the manufacturing cost of the housing bracket, thereby reducing the manufacturing cost of the housing assembly. Attached Figure Description

Embodiments of the present invention

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] Please refer to Figure 1. This application embodiment provides a housing assembly 10, including a connected housing cover plate 12 and a housing support 11, wherein the housing support 11 is assembled from multiple support units.

[0027] It should be noted that in the embodiments of this application, "multiple" refers to two or more, such as three, four, five, six, seven, eight, nine, ten, etc.

[0028] For example, each of the bracket units is provided with multiple hollow patterns 80, which can reduce the weight of the housing bracket 11, thereby reducing the weight of the housing assembly 10 and reducing the production cost of the housing assembly 10; the embodiments of this application, by adopting a combination of housing cover plate 12 (extruded board) and housing bracket 11, can make the housing assembly 10 thinner and more aesthetically pleasing.

[0029] For example, the housing assembly 10 can be used as the rear cover of a display device.

[0030] For example, the housing cover 12 is an extruded board. The board only requires an extrusion mold, which has low mold cost. The extruded board is thin, has few appearance defects, stable performance, and easy size control.

[0031] The housing assembly 10 provided in this application embodiment includes a connected housing cover plate 12 and a housing support 11. The housing support 11 can support the housing cover plate 12, thereby giving the housing assembly 10 high mechanical strength. Since the housing support 11 is composed of multiple support units, each support unit is manufactured using a small mold. In the prior art, housing supports are usually a one-piece structure manufactured by injection molding. Due to the large area of ​​the housing support and the different structures in each region, the mold used for injection molding the housing support is large and complex, resulting in high mold manufacturing costs and consequently high manufacturing costs for the housing support. This application embodiment... The housing support 11 is decomposed into multiple support units. Since the area of ​​a single support unit is small and the structure is relatively simple, a mold with a small area and a relatively simple structure can be used when injection molding a single support unit, thereby reducing the manufacturing cost of the mold. Moreover, compared with the method of injection molding the entire housing support, the injection molding yield of small support units is higher, thus reducing the manufacturing cost of the housing support 11. Furthermore, multiple support units can be injection molded using the same mold. After injection molding, support units with different structures can be obtained by appropriately cutting the resulting injection molded body. Therefore, this application can greatly reduce the manufacturing cost of the housing support 11, thereby reducing the manufacturing cost of the housing assembly 10.

[0032] For example, the housing support 11 and the housing cover 12 are connected by glue or double-sided tape.

[0033] Please refer to Figures 1 and 2. The housing support 11 includes a first support unit 51 and a second support unit 52 and a third support unit 53 located on both sides of the first support unit 51, respectively. The second support unit 52 and the third support unit 53 are both connected to the first support unit 51.

[0034] The second support unit 52 has a first opening area 521 on the side opposite to the first support unit 51;

[0035] The third support unit 53 has a second opening area 522 on the side opposite to the first support unit 51.

[0036] For example, the first support unit 51, the second support unit 52 and the third support unit 53 are each provided with a plurality of hollow patterns 80.

[0037] For example, the first support unit 51, the second support unit 52 and the third support unit 53 are all manufactured by injection molding and using the same mold. The second support unit 52 is cut to form the first opening area 521 after injection molding, and the third support unit 53 is cut to form the second opening area 522 after injection molding.

[0038] Referring to Figures 4 and 5, it can be seen that the second support unit 52 and the third support unit 53 can be obtained by cutting off the weak connection position 90 on the first support unit 51. Since the first support unit 51, the second support unit 52, and the third support unit 53 are prepared using the same mold, the mold cost and injection molding cost are low, thus reducing the production cost of the shell support 11. Compared with the technical solution of using a large mold to inject the shell support 11 in one injection, this proposal prepares three small supports and splices them together to obtain a large-sized shell support 11. Only one small mold is needed, resulting in low mold cost and low injection molding difficulty. The small supports serve as internal reinforcements, have no appearance requirements, and their size and deformation are easy to control, leading to a high injection molding yield.

[0039] Please refer to Figures 1 and 2. The housing assembly 10 also includes a power terminal bracket 61 for fixing power terminals (AC terminals). The power terminal bracket 61 is located in the first opening area 521 of the second bracket unit 52 and is connected to the housing cover plate 12.

[0040] For example, the housing cover 12 has an opening corresponding to the power terminal bracket 61 to expose the power terminal (AC terminal).

[0041] Please refer to Figures 1 and 2. The housing assembly 10 also includes a video interface terminal bracket 62 for fixing video interface terminals (AV terminals). The power terminal bracket 61 is located in the first opening area 521 of the second bracket unit 52. The video interface terminal bracket 62 is connected to the housing cover plate 12.

[0042] For example, the housing cover 12 has an opening corresponding to the video interface terminal bracket 62 to expose the video interface terminal (AV terminal).

[0043] It should be noted that, due to the special structure and small size of the power terminal bracket 61 and the video interface terminal bracket 62, the power terminal bracket 61 and the video interface terminal bracket 62 are made using smaller molds. Compared with the method of preparing the power terminal bracket 61 and the video interface terminal bracket 62 and the housing bracket 11 in the same injection molding process, the production cost can be reduced more effectively.

[0044] For example, the power terminal bracket 61 and the housing cover plate 12 are connected by adhesive or double-sided tape.

[0045] For example, the video interface terminal bracket 62 and the housing cover plate 12 are connected by adhesive or double-sided tape.

[0046] Please refer to Figures 1, 2 and 3. The housing support 11 also includes a first connector 71 and a second connector 72. The first connector 71 is used to connect the first support unit 51 and the second support unit 52, and the second connector 72 is used to connect the first support unit 51 and the third support unit 53.

[0047] For example, the first connector 71 and the second connector 72 have the same structure.

[0048] For example, the first connector 71 is connected to the first support unit 51 by screws, and the first connector 71 is connected to the second support unit 52 by screws.

[0049] For example, the first connector 71 is square, and two opposite sides of the first connector 71 are respectively connected and fixed to the first support unit 51 and the second support unit 52. Both sides of the first connector 71 are provided with round holes, and the first support unit 51 and the second support unit 52 are provided with screw holes corresponding to the round holes to facilitate bolt fixing. The first connector 71 is provided with a protrusion at the connection seam position of the first support unit 51 and the second support unit 52 (i.e., the center of the first connector 71) to avoid the edges of the first support unit 51 and the second support unit 52 when connecting them.

[0050] For example, the second connector 72 is connected to the first support unit 51 by screws, and the second connector 72 is connected to the third support unit 53 by screws.

[0051] Please refer to Figure 2. The second connector 72 is square. Two opposite sides of the second connector 72 are connected and fixed to the first support unit 51 and the third support unit 53, respectively. Both sides of the second connector 72 are provided with round holes. The first support unit 51 and the third support unit 53 are provided with screw holes corresponding to the round holes to facilitate bolt fixing. The second connector 72 is provided with a protrusion at the joint position of the first support unit 51 and the third support unit 53 (i.e., the center of the second connector 72) to avoid the edges of the first support unit 51 and the third support unit 53 when connecting them.

[0052] Please refer to Figure 6. This application embodiment provides a display device 100, which includes the housing assembly 10 as described above.

[0053] Please refer to Figure 6. The housing assembly 10 can be the rear shell of the display device 100.

[0054] For example, a gap is provided between the back panel 30 and the display panel 40, and an optical film group and a light source are disposed in the gap. The light emitted by the light source passes through the optical film group and displays image information on the display panel 40.

[0055] For example, the display device 100 can be a terminal such as a television, mobile phone, or tablet computer, or it can be a device with a display screen such as a gaming device, augmented reality (AR) device, virtual reality (VR) device, data storage device, audio playback device, video playback device, or wearable device. Wearable devices can be smart bracelets, smart glasses, smartwatches, smart decorations, etc.

[0056] Please refer to Figure 7. The display device also includes an elastic buckle 20 and a back plate 30. 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.

[0057] The inner side of the housing assembly 10 is provided with a first engaging groove 151; the elastic buckle 20 includes a first engaging part 23, which engages with the first engaging groove 151.

[0058] The display device 100 provided in this application embodiment connects the back plate 30 and the housing assembly 10 by means of an elastic buckle 20. The inner side of the housing assembly 10 is provided with a first engaging groove 151, which engages with the first engaging part 23 of the elastic buckle 20. Since the elastic buckle 20 is easy to deform under pressure, it can be easily separated from the housing assembly 10 when the display device 100 is repaired, thereby realizing the separation of the housing assembly 10 and the back plate 30. The housing assembly 10 is not easily damaged during disassembly, thus improving the maintainability of the display device 100. Furthermore, since the first engaging groove 151 on the housing assembly 10 is located inside the first plate 111, the outer surface of the housing assembly 10 is flat and smooth, and there is no need to set up destructive structures such as screw slots and connecting holes, thereby improving the appearance of the housing assembly 10 and thus improving the appearance of the display device.

[0059] It is understandable that since the elastic clip 20 is connected to the housing assembly 10 by a snap-fit ​​connection, when the elastic clip 20 is damaged, only the elastic clip 20 needs to be replaced instead of the entire housing assembly 10, resulting in lower maintenance costs.

[0060] Please refer to Figures 7, 8, 9 and 10. The housing support 11 is disposed toward the back plate 30. The housing support 11 includes a first plate 111 and a first protrusion 112. The first protrusion 112 is connected to the first plate 111 and protrudes toward the back plate 30. The inner surface of the first protrusion 112 and the housing cover plate 12 form a first engaging groove 151. The first protrusion 112 is provided with a first through hole 141, which communicates with the first engaging groove 151.

[0061] It is understandable that since the housing cover plate 12 is located outside the first engagement groove 151, the user cannot see the first engagement groove 151 from the outside. At this time, the outer surface of the housing cover plate 12 is the outer surface of the housing assembly 10. Since the outer surface of the housing cover plate 12 is flat, the outer surface of the housing assembly 10 seen by the user is flat, which can improve the overall appearance of the display device 100.

[0062] Please refer to Figures 7, 10, and 15. The elastic buckle 20 further includes a buckle body 21 and a first connecting part 22. The two ends of the first connecting part 22 are respectively connected to the buckle body 21 and the first engaging part 23. The first connecting part 22 passes through the first through hole 141. The first engaging part 23 is disposed in the first engaging groove 151. The orthographic projection of the first engaging part 23 on the plane of the first plate 111 and the orthographic projection of the buckle body 21 on the plane of the first plate 111 are both greater than the orthographic projection of the first through hole 141 on the plane of the first plate 111.

[0063] Please refer to Figures 7, 10 and 15. There is a gap between the first connecting part 22 of the elastic buckle 20 and the hole wall of the first through hole 141, and there is a gap between the first engaging part 23 of the elastic buckle 20 and the groove wall of the first engaging groove 151.

[0064] It should be noted that by designing a gap between the first connecting part 22 of the elastic buckle 20 and the wall of the first through hole 141, and a gap between the first engaging part 23 of the elastic buckle 20 and the wall of the first engaging groove 151, the elastic buckle 20 can move within the first through hole 141 and the first engaging groove 151. When the elastic buckle 20 is engaged with the back plate 30 and the second engaging part 25 of the elastic buckle 20 is misaligned within the second engaging groove 306 of the back plate 30, since the elastic buckle 20 itself is elastic and can move relative to each other within the first through hole 141 and the first engaging groove 151, the elastic buckle 20 can self-correct using its own elasticity, so that the position of the second engaging part 25 of the elastic buckle 20 within the second engaging groove 306 of the back plate 30 returns to the preset position.

[0065] For example, the first connecting part 22 is cylindrical, that is, the cross-section of the first connecting part 22 is circular, and the first through hole 141 is a circular hole. The diameter of the first through hole 141 is slightly larger than the diameter of the cross-section of the first connecting part 22, so that a gap is maintained between the first connecting part 22 of the elastic buckle 20 and the hole wall of the first through hole 141.

[0066] For example, both the first engaging groove 151 and the first engaging portion 23 are cylindrical, that is, the cross-sections of the first engaging groove 151 and the first engaging portion 23 are circular. 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 buckle 20 and the groove wall of the first engaging groove 151.

[0067] Please refer to Figure 12. The first side plate 120 has a first opening 121, which communicates with the first engaging groove 151. The first top plate 130 has a second opening 132, which communicates with the first through hole 141, so that the first engaging part 23 passes through the first opening 121 and enters the first engaging groove 151, and the first connecting part 22 passes through the second opening 132 and enters the first through hole 141.

[0068] For example, the second opening 132 is designed with a guide angle so that the first connecting part 22 of the elastic buckle 20 can more easily pass through the second opening 132 and enter the first through hole 141.

[0069] Please refer to 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.

[0070] Please refer to Figure 12. The housing assembly 10 is also provided with a guide groove 125. The guide groove 125 communicates 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.

[0071] Please refer to Figure 12. The housing support 11 is provided with a guide hole, and the wall of the guide hole and the housing cover plate 12 together form the guide groove 125.

[0072] Please refer to Figures 11 and 12. The installation process of the elastic snap-fit ​​20 and the housing assembly 10, in conjunction with Figures 11 and 12, is as follows: First, the elastic snap-fit ​​20 is placed in the guide groove 125. Then, the elastic snap-fit ​​20 is moved so that its first engaging portion 23 passes through the first opening 121 and enters the first engaging groove 151, and its first connecting portion 22 passes through the second opening 132 and enters the first through hole 141. It should be noted that the arrows in Figure 11 indicate the direction of movement of the elastic snap-fit ​​20 during installation.

[0073] Please refer to Figures 7 and 14. The back plate 30 is provided with a second engaging groove 306. The elastic buckle 20 also includes a buckle body 21 and a second engaging part 25. The first engaging part 23 and the second engaging part 25 are respectively provided on both sides of the buckle body 21 and are both connected to the buckle body 21. The second engaging part 25 is engaged with the second engaging groove 306.

[0074] Please refer to Figures 7, 13 and 14. The back plate 30 includes a third plate 31 and a second protrusion 32 connected to the third plate 31. The second protrusion 32 is provided with a second through hole 305. The second engagement groove 306 is formed between the inner surface of the second protrusion 32 and the plane where the plate is located.

[0075] Please refer to Figures 7, 10, and 15. The elastic buckle 20 further includes a second connecting portion 24. The two ends of the second connecting portion 24 are respectively connected to the buckle body 21 and the second engaging portion 25. The second connecting portion 24 passes through the second through hole 305. The second engaging portion 25 is disposed in the second engaging groove 306. The orthographic projection of the second engaging portion 25 on the plane where the third plate 31 is located and the orthographic projection of the buckle body 21 on the plane where the third plate 31 is located are both greater than the orthographic projection of the second through hole 305 on the plane where the third plate 31 is located.

[0076] Please refer to Figures 7, 14 and 15. The second protrusion 32 includes a second side plate 321 and a second top plate 322. One side of the second side plate 321 is connected to the third plate 31, and the other side is connected to the second top plate 322. The second top plate 322 is provided with the second through hole 305.

[0077] Please refer to Figures 7, 14 and 15. The second top plate 322 includes a horizontal portion 301, an inclined portion 302 and a vertical portion 303 arranged sequentially from the outside to the inside. The two sides of the inclined portion 302 are respectively connected to the horizontal portion 301 and the vertical portion 303. In the direction from the horizontal portion 301 to the third plate 31, the inclined portion 302 and the vertical portion 303 are arranged sequentially. The angle between the inclined portion 302 and the horizontal portion 301 is an obtuse angle. The vertical portion 303 is annular and surrounds the second through hole 305.

[0078] For example, the horizontal portion 301 is parallel to the third plate 31.

[0079] For example, the included angle between the inclined portion 302 and the vertical portion 303 is an obtuse angle, such as 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, etc.

[0080] Please refer to Figures 7, 14 and 15. In some embodiments, the horizontal portion 301 and the vertical portion 303 are perpendicular to each other.

[0081] For example, the included angle between the second side plate 321 and the third plate 31 is an obtuse angle, such as 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, etc.

[0082] For example, the included angle between the second side plate 321 and the horizontal portion 301 of the second top plate 322 is an obtuse angle, such as 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, etc.

[0083] Please refer to Figures 7, 10 and 15. The outer surface of the buckle body 21 includes an inclined surface 215 that cooperates with the inclined portion 302.

[0084] Referring to Figures 11 and 15, after connecting the resilient snap fastener 20 and the housing assembly 10, the housing assembly 10 can be moved toward the back plate 30. When the resilient snap fastener 20 installed on the housing assembly 10 contacts the back plate 30, simply pressing the housing assembly 10 appropriately will engage the second engaging portion 25 of the resilient snap fastener 20 with the second engaging groove 306 on the back plate 30. It should be noted that the arrows in Figures 11 and 15 indicate the direction of movement of the housing assembly 10 during installation.

[0085] For example, the elastic buckle 20 is integrally formed.

[0086] For example, the elastic buckle 20 is made of rubber. It is understood that rubber is relatively soft and has great elasticity, which allows the elastic buckle 20 to be repeatedly removed from the housing assembly 10 and the back plate 30 without easily damaging the housing assembly 10 and the back plate 30. It is easy to remove and has good maintainability.

[0087] Because the elastic buckle 20 is made of a relatively soft material, by connecting the housing assembly 10 and the back plate 30 through the elastic buckle 20, the mechanical vibration caused by the resonance of the housing assembly 10 and the back plate 30 during the operation of the speaker can be reduced.

[0088] Since the slot structure provided on the housing assembly 10 and the back plate 30 for engaging with the elastic buckle 20 is relatively simple, the manufacturing cost of the housing assembly 10 and the back plate 30 can be reduced, thereby reducing the manufacturing cost of the display device 100.

[0089] The housing assembly and display device provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application, and the descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
