Description

Technical Field

[0001] This disclosure belongs to the field of display technology, and particularly relates to a back cover assembly and a display device. Background Technology

[0002] With fierce competition in the display industry, cost control is a crucial means to enhance competitiveness. The back cover of display devices such as televisions is primarily manufactured using injection molding. In related technologies, there are two main methods for controlling back cover costs: one is to reduce the material cost by decreasing the back cover wall thickness, but this method carries the risk of reduced back cover strength; the other is to divide the back cover into three parts (left, middle, right, or top, middle, bottom). The middle part, corresponding to the circuit boards inside the display device, uses a relatively high-cost material to meet safety regulations, while the left and right or top and bottom parts are made of relatively low-cost materials to reduce material costs. However, this method requires at least three injection molds for the same display product, significantly increasing mold opening costs and consequently raising the back cover cost. Furthermore, injection molds not only have high opening costs but also result in a limited variety of textures for the molded products, leading to poor versatility. Only display products with very similar dimensions can share the same back cover injection mold, thus limiting the effectiveness of cost control.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] This disclosure aims to at least partially address the technical problem of how to effectively control the production cost of the back cover. To this end, this disclosure provides a back cover assembly and a display device.

[0013] The third corner piece, wherein the third corner piece is connectable to the end of the lower frame strip and is also connectable to the end of the left frame strip; and,

[0014] The fourth corner piece is capable of being grounded to the end of the lower frame strip and to the end of the right frame strip.

[0015] The rear plate, the upper frame strip, the lower frame strip, the left frame strip, and the right frame strip are manufactured by extrusion molding, while the first corner piece, the second corner piece, the third corner piece, and the fourth corner piece are manufactured by injection molding.

[0016] In some embodiments, the cross-section of the left frame strip is the same as the cross-section of the right frame strip.

[0017] In some embodiments, the cross-section of the upper frame strip is the same as the cross-section of the left frame strip.

[0018] In some embodiments, the structure of the first corner member is the same as that of the second corner member. The first corner member includes two first overlapping portions arranged at an angle, and the first overlapping portions overlap with one of the ends of the upper frame strip, the left frame strip, and the right frame strip.

[0019] In some embodiments, the first corner member further includes a first corner portion connected between the two first overlapping portions, the end face of the first corner portion matching the end face of the upper frame strip.

[0020] In some embodiments, the upper frame strip includes a frame portion and a rear plate overlap portion disposed at an angle to the frame portion, the frame portion overlapping with the first overlap portion, and the rear plate overlap portion overlapping with the rear plate.

[0021] In some embodiments, the structure of the third corner member is the same as that of the fourth corner member. The third corner member includes two third overlapping portions arranged at an angle, and the third overlapping portions overlap with one of the ends of the lower frame strip, the left frame strip, and the right frame strip.

[0022] In some embodiments, the lower frame strip includes a lower side frame portion and a lower side overlap portion disposed at an angle to the lower side frame portion. The lower side frame portion overlaps with the third overlap portion, and the lower side frame portion covers the end of the left frame strip or the end of the right frame strip. The lower side overlap portion overlaps with the rear plate.

[0023] In some embodiments, the rear housing assembly further includes an electrical socket and / or an input / output port, the electrical socket and / or the input / output port being manufactured using an injection molding process;

[0024] The rear panel has an electrical socket hole and / or an input / output port hole. The electrical socket hole can be connected to the electrical socket component, and the input / output port hole can be connected to the input / output port component.

[0025] This disclosure provides a display device, which includes the aforementioned rear shell assembly.

[0026] The embodiments disclosed herein have at least the following beneficial effects:

[0027] The aforementioned rear shell assembly can be assembled from a rear panel, upper frame strip, lower frame strip, left frame strip, right frame strip, first corner piece, second corner piece, third corner piece, and fourth corner piece. The dimensions of the rear panel, upper frame strip, lower frame strip, left frame strip, and right frame strip are closely related to the dimensions of the specific display product. Furthermore, the structure of the rear panel, upper frame strip, lower frame strip, left frame strip, and right frame strip is relatively simple. They are manufactured using an extrusion molding process. Extrusion molding allows for the creation of finished or semi-finished products with various cross-sectional shapes by changing the extrusion die at the extruder head. Semi-finished products can be cut into the corresponding finished products. This process offers advantages such as low extrusion die cost, high die versatility, low extrusion equipment cost, high production efficiency, and uniform and dense finished product quality. Using extrusion molding can effectively reduce the production cost of the rear panel, upper frame strip, lower frame strip, left frame strip, and right frame strip. The first, second, third, and fourth corner pieces are used to splice with the back panel, upper frame strip, lower frame strip, left frame strip, and right frame strip. The dimensions of the first, second, third, and fourth corner pieces are not strongly correlated with the dimensions of specific display products; therefore, their dimensions are highly versatile. However, the structures of the first, second, third, and fourth corner pieces are relatively complex. The corner pieces are manufactured using injection molding, which on the one hand can meet the manufacturing process requirements of the relatively complex structures of the first, second, third, and fourth corner pieces; on the other hand, only one injection mold needs to be configured for the first, second, third, and fourth corner pieces, which can reduce the size of a single injection mold and reduce the cost of a single injection mold; it can also improve the versatility of the injection mold, so that the first, second, third, and fourth corner pieces manufactured using this injection mold can be used in display products of different sizes.

[0039] The technical solutions of the embodiments of this disclosure 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 disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0040] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this disclosure. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this disclosure provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0041] The present disclosure is described below with reference to the accompanying drawings and specific embodiments:

[0042] To address the technical problem of effectively controlling the production cost of the back cover, this disclosure proposes a back cover assembly, such as... Figures 1 to 3 As shown, the rear shell assembly includes a rear panel 100, an upper frame strip 200, a lower frame strip 300, a left frame strip 400, a right frame strip 500, a first corner piece 600, a second corner piece 700, a third corner piece 800, and a fourth corner piece 900. The upper frame strip 200 is groundably connected to the upper side of the rear panel 100; the lower frame strip 300 is groundably connected to the lower side of the rear panel 100; the left frame strip 400 is groundably connected to the left side of the rear panel 100; the right frame strip 500 is groundably connected to the right side of the rear panel 100; the first corner piece 600 is groundably connected to the end of the upper frame strip 200 and also to the end of the left frame strip 400; the second corner piece 700... The end of the upper frame strip 200 can be connected to the ground, and the end of the right frame strip 500 can be connected to the ground; the end of the third corner piece 800 can be connected to the ground, and the end of the left frame strip 400 can be connected to the ground; the end of the fourth corner piece 900 can be connected to the ground, and the end of the lower frame strip 300 can be connected to the ground; the end of the fourth corner piece 900 can be connected to the ground, and the end of the right frame strip 500 can be connected to the ground; wherein, the rear plate 100, the upper frame strip 200, the lower frame strip 300, the left frame strip 400 and the right frame strip 500 are manufactured by extrusion molding, and the first corner piece 600, the second corner piece 700, the third corner piece 800 and the fourth corner piece 900 are manufactured by injection molding.

[0043] The rear shell assembly proposed in the embodiments of this disclosure, such as Figures 1 to 3As shown, it is assembled from the back panel 100, the upper frame strip 200, the lower frame strip 300, the left frame strip 400, the right frame strip 500, the first corner piece 600, the second corner piece 700, the third corner piece 800, and the fourth corner piece 900. The dimensions of the back panel 100, upper frame strip 200, lower frame strip 300, left frame strip 400, and right frame strip 500 are closely related to the dimensions of a specific display product. Furthermore, the structures of the back panel 100, upper frame strip 200, lower frame strip 300, left frame strip 400, and right frame strip 500 are relatively simple. These components are manufactured using an extrusion molding process. Extrusion molding allows for the creation of finished or semi-finished products with various cross-sectional shapes by changing the extrusion die at the extruder head. Semi-finished products can be cut into corresponding finished products. This process offers advantages such as lower extrusion die costs, higher die versatility, lower extrusion equipment costs, higher production efficiency, and more uniform and dense finished product quality. Using extrusion molding can effectively reduce the production costs of the back panel 100, upper frame strip 200, lower frame strip 300, left frame strip 400, and right frame strip 500. The first corner piece 600, the second corner piece 700, the third corner piece 800, and the fourth corner piece 900 are used to splice with the back panel 100, the upper frame strip 200, the lower frame strip 300, the left frame strip 400, and the right frame strip 500. The dimensions of the first corner piece 600, the second corner piece 700, the third corner piece 800, and the fourth corner piece 900 are not closely related to the dimensions of a specific display product. Therefore, the dimensions of the first corner piece 600, the second corner piece 700, the third corner piece 800, and the fourth corner piece 900 are relatively versatile. However, the structures of the first corner piece 600, the second corner piece 700, the third corner piece 800, and the fourth corner piece 900 are relatively complex. This is achieved by making the first corner piece 600, the second corner piece 700, the third corner piece 800, and the fourth corner piece 900... The first corner component 600, the second corner component 700, the third corner component 800, and the fourth corner component 900 are manufactured using injection molding. This process can meet the manufacturing requirements of the relatively complex structure of the first corner component 600, the second corner component 700, the third corner component 800, and the fourth corner component 900. Furthermore, only one injection mold needs to be configured for the first corner component 600, the second corner component 700, the third corner component 800, and the fourth corner component 900. This allows for a smaller size of each injection mold, reducing the cost of a single injection mold. It also improves the versatility of the injection mold, as the first corner component 600, the second corner component 700, the third corner component 800, and the fourth corner component 900 manufactured using this injection mold can be used in display products of different sizes.

[0044] The rear shell assembly proposed in the embodiments of this disclosure, such as Figures 1 to 3As shown, the back panel 100, upper frame strip 200, lower frame strip 300, left frame strip 400, and right frame strip 500 are made by extrusion molding process, which can have different extrusion textures to meet different appearance requirements and can avoid conflicts in the appearance of the products to a certain extent.

[0045] As an alternative implementation method, such as Figures 1 to 3 As shown, the cross-section of the left frame strip 400 is the same as the cross-section of the right frame strip 500.

[0046] In some embodiments of this disclosure, such as Figures 1 to 3 As shown, both the left frame strip 400 and the right frame strip 500 are manufactured using an extrusion molding process. By making the cross-section of the left frame strip 400 the same as that of the right frame strip 500, the left frame strip 400 and the right frame strip 500 can be manufactured using the same extrusion mold. This can further reduce the types of extrusion molds, lower the cost of extrusion molds, and thus further reduce the manufacturing cost of the rear shell assembly.

[0047] As an alternative implementation method, such as Figures 1 to 3 As shown, the cross-section of the upper frame strip 200 is the same as the cross-section of the left frame strip 400.

[0048] In some embodiments of this disclosure, such as Figures 1 to 4 As shown, both the upper frame strip 200 and the left frame strip 400 are manufactured using an extrusion molding process. By making the cross-section of the upper frame strip 200 the same as that of the left frame strip 400, the upper frame strip 200 and the left frame strip 400 can be manufactured using the same extrusion mold. By cutting the upper frame strip 200 and the left frame strip 400 to meet different design lengths, the types of extrusion molds can be further reduced, the cost of extrusion molds can be reduced, and the manufacturing cost of the rear shell assembly can be further reduced.

[0049] In some embodiments of this disclosure, such as Figures 1 to 4 As shown, the upper frame strip 200, the left frame strip 400, and the right frame strip 500 are all manufactured using an extrusion molding process. By making the cross-sections of the upper frame strip 200, the left frame strip 400, and the right frame strip 500 the same, the upper frame strip 200, the left frame strip 400, and the right frame strip 500 can all be manufactured using the same extrusion mold. By cutting the upper frame strip 200, the left frame strip 400, and the right frame strip 500 to meet different design lengths, the types of extrusion molds can be further reduced, the cost of extrusion molds can be reduced, and thus the manufacturing cost of the rear shell assembly can be further reduced.

[0050] As an alternative implementation method, such as Figures 3 to 6As shown, the structure of the first corner piece 600 is the same as that of the second corner piece 700. The first corner piece 600 includes two first overlapping portions 610 arranged at an angle. The first overlapping portion 610 overlaps with one of the ends of the upper frame strip 200, the left frame strip 400, and the right frame strip 500.

[0051] In some embodiments of this disclosure, such as Figures 3 to 6 As shown, when the cross-sections of the upper frame strip 200, the left frame strip 400, and the right frame strip 500 are all the same, and the end structures of the upper frame strip 200, the left frame strip 400, and the right frame strip 500 are all the same, the structure of the first corner piece 600 connecting the upper frame strip 200 and the left frame strip 400 can be the same as the structure of the second corner piece 700 connecting the upper frame strip 200 and the right frame strip 500. This allows the first corner piece 600 and the second corner piece 700 to be manufactured using the same injection mold, reducing the need for one corner piece injection mold and thus lowering the cost of the injection mold and the manufacturing cost of the rear shell assembly.

[0052] In some embodiments of this disclosure, such as Figures 3 to 6 As shown, the first corner piece 600 includes two first overlapping portions 610 arranged at an angle. Each first overlapping portion 610 overlaps with one of the ends of the upper frame strip 200, the left frame strip 400, or the right frame strip 500. Because the two first overlapping portions 610 of the first corner piece 600 are identical, the versatility of the first corner piece 600 is improved. That is, the first corner piece 600 can be identical to the second corner piece 700, allowing it to be used not only to connect the upper frame strip 200 and the left frame strip 400, but also to connect the upper frame strip 200 and the right frame strip 500. For example, one first overlapping portion 610 of the first corner piece 600 overlaps with the end of the upper frame strip 200, and the other first overlapping portion 610 overlaps with the end of the left frame strip 400, thereby connecting the upper frame strip 200 and the left frame strip 400 together. For example, one first overlapping portion 610 of the first corner piece 600 overlaps with the end of the upper frame strip 200, and the other first overlapping portion 610 of the first corner piece 600 overlaps with the end of the right frame strip 500, thereby connecting the upper frame strip 200 and the right frame strip 500 together.

[0053] In some embodiments of this disclosure, such as Figures 1 to 6 As shown, optionally, when the first overlapping portion 610 overlaps with one of the ends of the upper frame strip 200, the left frame strip 400, or the right frame strip 500, it can be fixed by an adhesive. For example, a two-component adhesive can be selected as the adhesive.

[0054] In some embodiments of this disclosure, such as Figures 1 to 6 As shown, when the upper frame strip 200 and the left frame strip 400 are set at right angles and the upper frame strip 200 and the right frame strip 500 are set at right angles, the included angle between the two first overlapping portions 610 of the first corner piece 600 is a right angle that matches them.

[0055] As an optional implementation, the first corner member 600 further includes a first corner portion 620 connected between the two first overlapping portions 610, the end face of the first corner portion 620 matching the end face of the upper frame strip 200.

[0056] In some embodiments of this disclosure, such as Figures 3 to 6 As shown, the two first overlapping portions 610 of the first corner piece 600 are connected together by a first corner portion 620. After the first overlapping portion 610 overlaps with one of the ends of the upper frame strip 200, the left frame strip 400, or the right frame strip 500, the end face of the first corner portion 620 fits against one of the ends of the upper frame strip 200, the left frame strip 400, or the right frame strip 500. This is achieved by making the first corner portion 620... The end face of 0 matches the end face of the upper frame strip 200. When the cross-sections of the upper frame strip 200, the left frame strip 400, and the right frame strip 500 are all the same, the end face of the upper frame strip 200 is the same as the end face of the left frame strip 400 and the end face of the right frame strip 500. Therefore, the end face of the first corner 620 matches the end face of the upper frame strip 200, the end face of the left frame strip 400, and the end face of the right frame strip 500. After the upper frame strip 200 and the left frame strip 400 are connected by the first corner piece 600, the two end faces of the first corner portion 620 are respectively attached to the end faces of the upper frame strip 200 and the left frame strip 400. After the upper frame strip 200 and the right frame strip 500 are connected by the first corner piece 600, the two end faces of the first corner portion 620 are respectively attached to the end faces of the upper frame strip 200 and the right frame strip 500, thus forming a structure in which the left frame strip 400, the first corner piece 600, the upper frame strip 200, the first corner piece 600, and the right frame strip 500 are sequentially attached and connected, thereby forming a continuous structure in appearance, making the back shell assembly complete and beautiful after splicing and connection.

[0057] As an optional implementation, the upper frame strip 200 includes a frame portion 210 and a rear plate overlap portion 220 that is angled to the frame portion 210. The frame portion 210 overlaps with the first overlap portion 610, and the rear plate overlap portion 220 overlaps with the rear plate 100.

[0058] In some embodiments of this disclosure, such as Figures 3 to 6As shown, the upper frame strip 200 includes a frame portion 210 and a back panel overlap portion 220 that is angled to the frame portion 210. Furthermore, assuming the cross-sections of the upper frame strip 200, the left frame strip 400, and the right frame strip 500 are all identical, the left frame strip 400 also includes a frame portion 210 and a back panel overlap portion 220 that is angled to the frame portion 210, and the right frame strip 500 also includes a frame portion 210 and a back panel overlap portion 220 that is angled to the frame portion 210. The frame portions 210 of each of the upper frame strip 200, left frame strip 400, and right frame strip 500 can overlap with the first overlap portion 610, thereby achieving connection with the first corner piece 600. The first corner piece 600 then enables the splicing connection between the upper frame strip 200, left frame strip 400, and right frame strip 500. The back panel overlap portions 220 of the upper frame strip 200, left frame strip 400, and right frame strip 500 can be used to overlap with the back panel 100, thereby achieving splicing connections between the upper frame strip 200, left frame strip 400, and right frame strip 500 and the back panel 100. Optionally, when the back panel overlap portions 220 overlap with the back panel 100, they can be fixed with adhesive. For example, double-sided tape can be selected as the adhesive.

[0059] In some embodiments of this disclosure, optionally, such as Figure 6 As shown, the edge portion 210 of the upper frame strip 200 has a cavity. When the edge portion 210 overlaps with the first overlapping portion 610, the first overlapping portion 610 can be placed in the cavity of the edge portion 210 to hide the first overlapping portion 610 within the cavity. When the cross-sections of the upper frame strip 200, the left frame strip 400, and the right frame strip 500 are all the same, the edge portions 210 of the left frame strip 400 and the right frame strip 500 also have cavities. When the left frame strip 400 and the right frame strip 500 overlap with the first overlapping portion 610 respectively, the first overlapping portion 610 can be placed in the corresponding cavities of the left frame strip 400 and the right frame strip 500.

[0060] As an alternative implementation method, such as Figures 3 to 7 As shown, the structure of the third corner piece 800 is the same as that of the fourth corner piece 900. The third corner piece 800 includes two third overlapping portions 810 arranged at an angle. The third overlapping portion 810 overlaps with one of the ends of the lower frame strip 300, the left frame strip 400, and the right frame strip 500.

[0061] In some embodiments of this disclosure, such as Figures 3 to 7As shown, when the cross-sections of the left frame strip 400 and the right frame strip 500 are the same, and the end structures of the left frame strip 400 and the right frame strip 500 are the same, the structure of the third corner piece 800 connecting the lower frame strip 300 and the left frame strip 400 can be the same as the structure of the third corner piece connecting the lower frame strip 300 and the right frame strip 500. This allows the third corner piece 800 and the fourth corner piece 900 to be manufactured using the same injection mold, reducing the need for one corner piece injection mold and thus lowering the cost of the injection mold and the manufacturing cost of the rear shell assembly.

[0062] In some embodiments of this disclosure, such as Figures 3 to 7 As shown, the third corner piece 800 includes two third overlapping portions 810 arranged at an angle. Each third overlapping portion 810 overlaps with one of the ends of the lower frame strip 300, the left frame strip 400, or the right frame strip 500. Because the two third overlapping portions 810 of the third corner piece 800 are identical, the versatility of the third corner piece 800 is improved. That is, the third corner piece 800 can be identical to the fourth corner piece 900, allowing it to be used not only to connect the lower frame strip 300 and the left frame strip 400, but also to connect the lower frame strip 300 and the right frame strip 500. For example, one third overlapping portion 810 of the third corner piece 800 overlaps with the end of the lower frame strip 300, and the other third overlapping portion 810 overlaps with the end of the left frame strip 400, thereby connecting the lower frame strip 300 and the left frame strip 400 together. For example, one third overlapping portion 810 of the third corner piece 800 overlaps with the end of the lower frame strip 300, and the other third overlapping portion 810 of the third corner piece 800 overlaps with the end of the right frame strip 500, thereby connecting the lower frame strip 300 and the right frame strip 500 together.

[0063] In some embodiments of this disclosure, such as Figures 3 to 7 As shown, optionally, when the third overlapping portion 810 overlaps with one of the ends of the lower frame strip 300, the left frame strip 400, or the right frame strip 500, it can be fixed by an adhesive. For example, a two-component adhesive can be selected as the adhesive.

[0064] In some embodiments of this disclosure, such as Figures 3 to 7 As shown, when the lower frame strip 300 is set at a right angle to the left frame strip 400 and the lower frame strip 300 is set at a right angle to the right frame strip 500, the included angle between the two third overlapping portions 810 of the third corner piece 800 is a right angle that matches it.

[0065] As an alternative implementation method, such as Figures 3 to 7As shown, the lower frame strip 300 includes a lower frame portion 310 and a lower overlap portion 320 that is angled to the lower frame portion 310. The lower frame portion 310 overlaps with the third overlap portion 810, and the lower frame portion 310 covers the end of the left frame strip 400 or the end of the right frame strip 500. The lower overlap portion 320 overlaps with the rear plate 100.

[0066] In some embodiments of this disclosure, such as Figures 3 to 7 As shown, the lower frame strip 300 includes a lower side frame portion 310 and a lower overlapping portion 320 that is angled to the lower side frame portion 310. The lower side frame portion 310 overlaps with the third overlapping portion 810, thereby achieving connection with the third corner piece 800. In turn, the splicing connection between the lower frame strip 300, the left frame strip 400, and the right frame strip 500 is achieved through the third corner piece 800. At the same time, while the lower side frame portion 310 overlaps with the third overlapping portion 810, by covering the end of the left frame strip 400 or the end of the right frame strip 500 with the lower side frame portion 310, the third corner piece 800, the end of the left frame strip 400 and the end of the right frame strip 500 can be hidden by the lower side frame portion 310. This makes the connection between the lower frame strip 300 and the left frame strip 400 and the connection between the lower frame strip 300 and the right frame strip 500 form a continuous structure in appearance, so that the back shell assembly is complete and beautiful after splicing and connecting.

[0067] In some embodiments of this disclosure, such as Figures 3 to 7 As shown, the lower overlap portion 320 of the lower frame strip 300 overlaps with the back plate 100, thereby achieving a splicing connection between the lower frame strip 300 and the back plate 100. Optionally, when the back plate overlap portion 220 overlaps with the back plate 100, it can be fixed by adhesive. For example, double-sided tape can be selected as the adhesive.

[0068] In some embodiments of this disclosure, optionally, such as Figure 7 As shown, the lower side of the rear shell assembly can be provided with through-hole structures such as switch holes, heat dissipation holes, and audio jacks. By making the lower side frame portion 310 of the lower frame strip 300 plate-shaped, it is easier to form through-hole structures such as switch holes, heat dissipation holes, and audio jacks on the lower frame strip 300, which is made by extrusion molding process, by cutting or other means.

[0069] As an alternative implementation method, such as Figures 1 to 3As shown, the rear housing assembly also includes an electrical socket 1000 and / or an input / output (I / O) port 1100, which are manufactured using injection molding. The rear panel 100 has an electrical socket hole 110 and / or an input / output port hole 120. The electrical socket hole 110 can be connected to the electrical socket 1000, and the input / output port hole 120 can be connected to the input / output port 1100.

[0070] In some embodiments of this disclosure, such as Figures 1 to 3 As shown, the rear shell assembly also includes an electrical socket component 1000. The electrical socket component 1000 generally has a relatively complex structure, and therefore can be manufactured using injection molding. Since the rear plate 100 is manufactured using extrusion molding, electrical socket holes 110 can be formed on the rear plate 100 by cutting or other methods, allowing the rear plate 100 to be connected to the electrical socket component 1000 via the electrical socket holes 110. Optionally, when the rear plate 100 is connected to the electrical socket component 1000 via the electrical socket holes 110, it can be fixed with adhesive. For example, a two-component adhesive can be selected.

[0071] In some embodiments of this disclosure, such as Figures 1 to 3 As shown, the rear housing assembly also includes an input / output port component 1100. The structure of the input / output port component 1100 is generally relatively complex, and therefore it can be manufactured using injection molding. Since the rear plate 100 is manufactured using extrusion molding, input / output port holes 120 can be formed on the rear plate 100 by cutting or other methods, allowing the rear plate 100 to be connected to the input / output port component 1100 via the input / output port holes 120. Optionally, when the rear plate 100 is connected to the input / output port component 1100 via the input / output port holes 120, it can be fixed with an adhesive. For example, a two-component adhesive can be selected.

[0072] Based on the same inventive concept, this disclosure also proposes a display device, such as... Figure 8 As shown, the display device includes the aforementioned rear shell assembly.

[0073] Since the display device provided by this utility model includes the rear shell assembly of the above-mentioned technical solution, the display device provided by this utility model has all the beneficial effects of the above-mentioned rear shell assembly, which will not be elaborated here.

[0074] In some embodiments of this disclosure, such as Figure 8As shown, the rear panel 100, upper frame strip 200, lower frame strip 300, left frame strip 400, right frame strip 500, first corner piece 600, second corner piece 700, third corner piece 800 and fourth corner piece 900 of the rear shell assembly are assembled and spliced ​​together, and the combined rear shell can be fixed to the back panel 1200 of the display device by screws and other connecting parts. For display devices of different sizes, the length of the frame strips manufactured by the extrusion molding process can be adjusted to form the upper frame strip 200, lower frame strip 300, left frame strip 400, and right frame strip 500 of corresponding sizes. The back plate 100 of corresponding sizes can be formed by adjusting the sheet material manufactured by the extrusion molding process. The first corner piece 600, the second corner piece 700, the third corner piece 800, and the fourth corner piece 900 are interchangeable for display devices of different sizes, thereby reducing the production cost of the first corner piece 600, the second corner piece 700, the third corner piece 800, and the fourth corner piece 900, and thus reducing the overall cost of producing display devices of different sizes.
