Description

Technical Field

[0001] This utility model relates to the field of television accessories technology, and in particular to a split-type support device for large-screen televisions. Background Technology

[0002] With the rapid development of ultra-high-definition display technology, 75-inch and larger large-screen TVs are gradually becoming the mainstream products in the home audio-visual market. The continued demand for thinner and lighter large-screen LCD TVs, coupled with cost control requirements, is driving changes in display module structure design. Currently, the mainstream solution for TV bezels in the TV manufacturing industry is a dual-component architecture of "plastic mid-frame - integrated bent metal bezel." In this structure, the plastic mid-frame is injection molded and used to hold the optical film, while the integrated bent metal bezel supports the LCD panel. However, in actual production, this solution increases production costs because the mid-frame needs to be injection molded separately. Furthermore, the assembly process of the mid-frame is relatively cumbersome, reducing production efficiency. In addition, the integrated bent bezel is prone to deformation during transportation due to stress concentration, leading to quality control issues such as screen light leakage.

[0003] In summary, developing a load-bearing device that reduces frame production costs, stably supports television components, and possesses high strength is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a split-type support device for large-size televisions, which solves the technical problems of high production costs of existing frame structures and the concentrated load distribution at the bending points of integrated frames, which easily leads to deformation and reduces the quality control of televisions.

[0005] To achieve the above objectives, this utility model provides a split-type support device for large-screen televisions, comprising:

[0006] Three load-bearing side plates, each of which can be vertically spliced. The load-bearing side plates include:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] This utility model provides a split-type support device for large-screen televisions. Please refer to the appendix of the instruction manual. Figures 1 to 4The large-size television's split-type support device includes three support side plates 3. Each support side plate 3 has a connecting plate 31 for fixing the LCD panel 1. The connecting plate 31 is attached to the edge of the LCD panel 1's end face. Furthermore, a fixing plate 32 is provided on the side of the connecting plate 31 facing away from the LCD panel 1. The fixing plate 32 is perpendicular to the connecting plate 31, and its end abuts against the television back panel 6. A connector 7 is vertically inserted through the end face of the television back panel 6, extending into the fixing plate 32 along its height direction. The supporting side plate 3, together with the LCD panel 1, is fixed to the TV back plate 6. In addition, an optical film 5 is supported on the side of the TV back plate 6 facing the LCD panel 1. The optical film 5 is connected to the TV back plate 6 by a connecting plate 31. The sides of the optical film 5 abut against the side walls of each fixing plate 32. Each fixing plate 32 determines the setting position of the optical film 5. The connecting plate 31 and the TV back plate 6 clamp the optical film 5 to prevent the optical film 5 from slipping. The connecting plate 31 and the TV back plate 6 work together, and the supporting device does not need to add additional components to hold the optical film 5.

[0026] It should be noted that the three load-bearing side plates 3 include two short plates of equal length and one long plate. The two short plates are perpendicularly connected to the two ends of the long plate. The ends of each load-bearing side plate 3 that meet each other are provided with a mating bevel, and the included angles of adjacent mating bevels are complementary, ensuring that the load-bearing side plates 3 are tightly connected after mating.

[0027] Please refer to the instruction manual appendix. Figure 2 The TV back panel 6 includes a receiving portion for mounting electrical components. A bent portion extends from the edge of the receiving portion. Specifically, the bent portion is L-shaped and consists of a first plate and a second plate that are perpendicular to each other. The first plate is attached to the optical film 5, and the second plate is bent towards the side closer to the LCD panel 1. Furthermore, a stop plate 34 is provided on the edge of the connecting plate 31 facing away from the LCD panel 1. The stop plate 34 is parallel to the fixing plate 32, and there is a gap between them. A snap-fit ​​groove 33 is formed between the stop plate 34 and the fixing plate 32. The first plate is attached to the optical film 5, and the stop plate... 34 is perpendicular to the optical film 5, that is, the groove depth direction of the snap-fit ​​groove 33 is the same as the extension direction of the second plate. When assembling the bearing side plate 3 and the TV back plate 6, the snap-fit ​​groove 33 is first connected to the second plate to determine the position of the TV back plate and the bearing side plate 3. Then, it is further fixed by the connector 7 to prevent the bearing side plate 3 from rotating with the connector 7 due to insufficient number of connectors 7 installed in the early stage of installation, or the bearing side plate 3 from shifting due to vibration when other parts are placed, resulting in an irregular product appearance.

[0028] Furthermore, adhesive tape 2 is pasted on the side of the connecting plate 31 away from the TV back plate 6. Preferably, both sides of the adhesive tape 2 are adhesive. The adhesive tape 2 is attached to the LCD panel 1, fixing the LCD panel 1 to each of the supporting side plates 3. In addition, a pressure pad 4 is provided on the side of the connecting plate 31 away from the LCD panel 1. The pressure pad 4 is pasted and fixed to the connecting plate 31. The other end face of the pressure pad 4 is not adhesive, but has a friction texture. Preferably, the pressure pad 4 is made of elastic material. The thickness of the pressure pad 4 is slightly greater than the distance between the optical film 5 and the connecting plate 31. After the TV back plate 6 is fixedly connected to the supporting side plate 3, the first plate and the connecting plate 31 clamp the pressure pad 4 and the optical film 5, so that the pressure pad 4 and the optical film 5 are tightly attached to each other, preventing the optical film 5 from sliding between the supporting side plates 3, thereby affecting the TV display performance.

[0029] Please refer to the instruction manual appendix. Figure 2 With appendix Figure 3 The stop plate 34 extends away from the fixed plate 32. A limiting part 35 is provided on the edge of the connecting plate 31 away from the stop plate 34. The limiting part 35 extends along the thickness direction of the connecting plate 31. That is, at this time, both sides of the connecting plate 31 along the length direction are higher than the end face of the connecting plate 31. A first groove and a second groove are formed between the stop plate 34 and the limiting part 35, and between the fixed plate 32 and the limiting part 35. The first groove is used to set the tape 2, and the second groove is used to set the pressure pad 4. The first groove and the second groove limit the setting range of the tape 2 and the pressure pad 4, so as to avoid the lack of positioning reference during the pasting process, which would lead to the position being skewed and affect the firmness of the tape 2 or the positioning effect of the pressure pad 4. Preferably, the width of the first groove and the second groove is slightly larger than the width of the tape 2 and the pressure pad 4. When the operator is pasting, there is enough space to adjust the pasting direction of the pressure pad 4 and the tape 2. At the same time, the limiting part 35 can be used as a direction reference to ensure that the tape 2 is within the specified range after pasting.

[0030] Please continue to refer to the instruction manual appendix. Figure 3 Mounting holes are provided in the fixing plate 32. The extension direction of each mounting hole is perpendicular to the connecting plate 31. The first plate body is provided with clearance holes at the positions corresponding to each mounting hole. The inner wall of the mounting hole is provided with threads. The connecting piece 7 can be specifically a fastening nut. When the fastening nut is tightened, the screw head of the fastening nut abuts against the first plate body, and the TV back plate 6 is fixedly connected to the bearing side plate 3.

[0031] In one embodiment of this application, the TV back panel 6 is locked at the assembly station with its port facing upwards. The optical film 5 is placed on the first plate of the TV back panel 6. The optical film 5 can be positioned by the contour formed by the clearance holes. Then, the second plate is connected to the snap-fit ​​grooves 33 of each supporting side plate 3. After that, the TV back panel 6 is fixed to the snap-fit ​​groove by screwing the connector 7. The pressure pad 4 also tightly presses the optical film 5. The tape 2 is pasted on the connecting plate 31. The LCD panel 1 is placed in the area surrounded by the stop plate 34. The LCD panel 1 is pressed to complete the TV assembly.

[0032] The supporting device provided by this utility model consists of only three supporting side plates 3 with identical cross sections. In the production process of the supporting side plates 3, only one molding mold is used, which reduces the production cost of the TV bezel. At the same time, the simple structure of the supporting device simplifies the TV assembly process and improves production efficiency. By fixing the pressure pad 4 between the connecting plate 31 and the TV back plate 6, the optical film 5 is stabilized. The pressure pad 4 replaces the middle frame of the dual-component frame, reducing material loss and lightening the weight of the TV, reducing the load on the supporting side plates 3, and further reducing the risk of TV quality degradation due to bezel deformation.

[0033] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0034] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
