Description

Technical Field

[0001] This application relates to the field of display device technology, and more particularly to a display device. Background Technology

[0002] As large-size LCD displays of 75 inches and above gain a larger market share, and as the weight of these displays increases, displays weighing 30-50KG or more are now commonplace, and more and more users are opting for desktop placement. Therefore, the design of support components to support the main body of the display device is becoming increasingly important.

[0003] In the existing technology, when the display device is placed vertically, the weight of the whole machine is vertically downward. Under the action of the weight of the whole machine, a large torque will be generated at the connection between the base and the bracket and the connection between the bracket and the whole machine. In addition, during the process of lifting and moving the machine, it is easy for the base connection to break when the machine is dropped to the ground by a person. If the connection between the bracket and the whole machine is unreliable, it is easy to cause the connection between the base and the bracket to fail, resulting in poor drop resistance.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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 some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0036] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inner," "outer," "upper," "lower," "front," "rear," "vertical," "lateral," "length," "width," "thickness," "left," "right," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0037] In the description of this application, "multiple" means two or more.

[0038] In order to solve the technical problems of poor drop resistance and low structural strength of existing display devices, this application provides a display device 1, which has good drop resistance, good structural strength, and is easy to install.

[0039] The display device 1 of the present application, including a back plate 200 and a support assembly 100, is described below with reference to the accompanying drawings.

[0040] Specifically, such as Figures 1-2 As shown, the support assembly 100 includes a bracket 20, a connecting column 10, and a base 30. The bracket 20 is connected to the back plate 200. One end of the connecting column 10 extends into the bracket 20 and is threadedly connected to the bracket 20. The base 30 is located below the bracket 20. The base 30 includes a base body 31 and a first fastener 32. The other end of the connecting column 10 is connected to the base body 31 and is located inside the base body 31. One end of the first fastener 32 extends from the bottom of the base body 31 into the base body 31 and is threadedly connected to the connecting column 10.

[0041] It is understandable that by setting the connecting post 10, both ends of the connecting post 10 can be installed and connected to the bracket 20 and the base 30 respectively, so as to connect the bracket 20 and the base 30 together and ensure the stability of the connection. However, in the prior art, the connection method between the bracket and the base body is generally that the bracket is provided with a stud integrally formed with the bracket, and the stud is threaded to the base, or the base is provided with a stud integrally formed with the base, and the stud is threaded to the bracket. When the display device is subjected to external force, such as falling to the ground or during movement, there is a risk of breakage. Compared with the above-mentioned arrangement, the embodiment of this application, by making the connecting post 10 threadedly connected to the bracket 20 and the base 30 respectively, can realize the transmission of torque through the connecting post 10. The connecting post 10 can play the role of resisting and dispersing the transmitted force, reducing the risk of breakage, making the structure of the support component 100 more reliable, with better drop protection, thereby improving the structural reliability of the display device 1.

[0042] In addition, the two ends of the connecting column 10 are threaded to the bracket 20 and the base 30 respectively, which can facilitate the installation and disassembly of the support component 100, making the installation and adjustment of the support component 100 simple and flexible.

[0043] Furthermore, by setting a first fastener 32 and installing the first fastener 32 from the bottom of the base body 31, this application can further improve the anti-fall effect. At the same time, this setting is convenient for installation and can improve installation efficiency. On the other hand, it can further disperse the force transmission, improve the structural reliability of the support component 100, and improve the anti-fall effect.

[0044] The support component 100 provided in this embodiment of the application, by setting a connecting column 10, with both ends of the connecting column 10 threadedly connected to the bracket 20 and the base 30 respectively, can play a role in resisting and dispersing the force when subjected to external force, thereby improving the drop resistance of the display device 1 and providing good structural strength. At the same time, by setting the first fastener 32, the drop resistance can be further improved and installation is convenient.

[0045] In some embodiments, such as Figure 3 , Figure 4As shown, the bracket 20 has a first mounting groove 21 with a first internal thread, and the outer peripheral surface of one end of the connecting column 10 has a first external thread that connects with the first internal thread; and / or, the other end of the connecting column 10 has a second mounting groove 13 with a second internal thread, and the outer peripheral surface of one end of the first fastener 32 has a second external thread, the first fastener 32 extending into the second mounting groove 13 to connect the second internal thread with the second external thread. Thus, by providing the first mounting groove 21 and the second mounting groove 13, the contact area between the connecting column 10 and the bracket 20, and between the connecting column 10 and the base 30, can be increased, which helps to improve the stability of the distributed force transmission and ensures a tight and stable connection between the bracket 20 and the connecting column 10, and between the base 30 and the connecting column 10, thereby improving the reliability of the support assembly 100 when supporting the back plate 200.

[0046] In some embodiments, such as Figure 4 As shown, one of the bracket 20 and the base 30 has a first positioning post 22, and the other of the bracket 20 and the base 30 has a first positioning hole 33. The first positioning post 22 and the first positioning hole 33 are inserted into each other. Thus, the first positioning hole 33 and the first positioning post 22 can play a positioning role, and can withstand corresponding weight and pressure, participating in the force distribution. At the same time, it can also make the installation and disassembly process more convenient and simple, improving the efficiency of loading and unloading.

[0047] In some embodiments, refer to Figure 6 The connecting columns 10 are multiple and spaced apart, including a first column 11 and a second column 12. The bracket 20 has a first positioning column 22 located between the first column 11 and the second column 12. The distance between the central axis of the first column 11 and the central axis of the first positioning column 22 is greater than the distance between the central axis of the second column 12 and the central axis of the first positioning column 22; and / or, the plane containing the central axes of the first column 11 and the second column 12 is inclined relative to the vertical direction. By making the distance between the central axis of the first column 11 and the central axis of the first positioning column 22 greater than the distance between the central axis of the second column 12 and the central axis of the first positioning column 22, an eccentric design of the first positioning column 22 is achieved, providing a foolproof function when installing the base 30 and the bracket 20. Alternatively, the plane containing the central axis of the first column 11 and the central axis of the second column 12 can be inclined relative to the vertical direction. For example, the first column 11 and the second column 12 can be arranged adjacent to the two diagonals of the bottom surface of the bracket 20. This can increase the usable area, increase the distance between the first column 11 and the second column 12, improve the structural reliability of the bracket 20, better distribute the force transmission, and achieve the foolproof function.

[0048] Of course, the distance between the central axis of the first column 11 and the central axis of the first positioning column 22 can be greater than the distance between the central axis of the second column 12 and the central axis of the first positioning column 22. Simultaneously, the plane containing the central axes of the first column 11 and the second column 12 is inclined relative to the vertical direction. Therefore, while improving the structural reliability of the bracket 20 and ensuring force transmission, it can further enhance the error-proofing effect and improve assembly efficiency.

[0049] In some embodiments, such as Figure 6 As shown, the bracket 20 includes a bracket body 23 and a bracket cover plate 24. The bracket body 23 is connected to the back plate 200. The bracket cover plate 24 is installed on the side of the bracket body 23 facing the base 30. The bracket cover plate 24 has a protrusion 241 with a third mounting groove 241a. By providing the protrusion 241, the structural strength of the bracket 20 can be improved. The base 30 partially fits into the third mounting groove 241a, and the inner contour of the third mounting groove 241a is adapted to the outer surface of the base 30 facing the bracket 20. On the one hand, this ensures a tight connection and stable fixation between the base 30 and the bracket 20, so that the support assembly 100 provides better stability when providing support force. On the other hand, it ensures the fit between the bracket 20 and the base 30, preventing gaps that could lead to breakage under external force and preventing connection failure. For example, refer to... Figure 4 , Figure 6 The bracket body 23 has a groove (not shown in the figure), the bracket cover plate 24 is embedded in the groove, the connecting post 10 passes through the bracket cover plate 24 and extends into the first mounting groove 21 of the bracket body 23 and is threadedly connected to the first mounting groove 21 to ensure the connection stability between the bracket body 23 and the bracket cover plate 24, and between the bracket 20 and the base 30.

[0050] In some embodiments, such as Figure 3 and Figure 4 As shown, the outer peripheral surface of the connecting post 10 has an annular protrusion 14, which is connected to the end of the first external thread facing the base 30. That is, both the first external thread and the annular protrusion 14 are formed on the outer peripheral surface of the connecting post 10, with the annular protrusion 14 located at the end of the first external thread facing the base 30 and connected to the first external thread. By providing the annular protrusion 14, the assembly accuracy of the connecting post 10 and the bracket 20 can be improved. Specifically, the installation is complete when the first mounting groove 21 of the bracket 20 abuts against the annular protrusion 14, ensuring the reliability of the support assembly 100 installation and improving the drop resistance of the display device 1.

[0051] For example, the first mounting groove 21 can be formed on the bracket body 23. During installation, the first external thread of the connecting post 10 is threaded into the first internal thread of the first mounting groove 21 to assemble the connecting post 10 and the bracket body 23 together. At this time, the first mounting groove 21 can abut against the annular protrusion 14. The bracket cover plate 24 is embedded in the groove of the bracket body 23, and the side of the bracket cover plate 24 facing the bracket body 23 can abut against the annular protrusion 14. That is to say, after installation, the two ends of the annular protrusion 14 can abut against the bracket body 23 and the bracket cover plate 24. The annular protrusion 14 can play a positioning role, thereby ensuring the stability of the installation. At the same time, it can ensure that the annular protrusion 14 further distributes the force between the bracket body 23 and the bracket cover plate 24, so as to further improve the impact resistance of the support assembly 100.

[0052] In some embodiments, the bracket 20 is a die-cast aluminum alloy part and / or the connecting column 10 is a steel part. Die-cast aluminum alloy has high strength, and the die-cast aluminum alloy bracket 20 can provide good support and stability, suitable for bearing weight and pressure. Steel parts have high strength and rigidity, can withstand large bending moments, and have a certain degree of toughness, so they will not break even if they are bent and deformed. This avoids the risk of brittle fracture of the studs directly integrally formed on the die-cast aluminum alloy bracket 20. At the same time, it can withstand high pressure and extrusion pressure, and can distribute the force to ensure that the support assembly 100 will not deform or loosen under the weight of the whole machine or under external forces during transportation. The support assembly 100 has high bending moment resistance.

[0053] For example, the base 30 is constructed as a constricted tube, that is, the diameter of the tube in the middle is large and the diameter of the tube at both ends is small. The material is high manganese steel, which is a steel with a high manganese content, usually containing 12%-14% manganese. Therefore, it has good hardness and wear resistance, as well as high strength and good toughness, which can improve impact resistance and structural stability.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the base 30 is constructed in a figure-eight shape. Compared to a straight base, the figure-eight base 30 is more aesthetically pleasing. However, the line connecting the fulcrum of the figure-eight base 30 and the center of the bracket 20 are generally not in the same plane. Under the action of the weight of the whole machine, a large torque will be generated at the connection between the base 30 and the bracket 20 and at the connection between the bracket 20 and the whole machine. Therefore, by setting the connecting column 10, the torque can be effectively reduced, participate in the force distribution, and improve the support stability and structural reliability of the support structure.

[0055] In some embodiments, the display device 1 can be a television. For example, it can be a large LCD television. Large LCD televisions are large in size and heavy in weight. By providing the support component 100, the large LCD television can be supported more effectively, preventing the connection between the base 30 and the bracket 20 from failing and thus preventing it from being dropped.

[0056] In some embodiments, such as Figure 1 and Figure 2 As shown, the display device 1 may also include a back plate 200, which is the main body of the display device 1. The back plate 200 is used to fix the display panel (not shown), backlight components, and motherboard, etc. The back side of the back plate 200 has at least one reinforcing rib, and the bracket 20 has a mounting part 25 extending in the vertical direction, which is connected to the reinforcing rib. That is to say, the mounting part 25 of the support component 100 is connected to the back side of the back plate 200. Currently, TVs are generally heavy and large in size. Therefore, the installation of many bases 30 requires the entire unit to be laid flat on the table and installed from the bottom. However, it is obviously inconvenient to lay large TVs of 75 inches or more flat. On the one hand, it is not easy to find a large table, and on the other hand, it is not easy to change a large TV from upright to flat. Moreover, most large TVs nowadays adopt a frameless design, and the gap between the LCD glass and the whole unit is small. If the large TV is unbalanced during the flat placement process, causing the TV to twist, it is easy to cause the LCD glass to break. Therefore, by connecting the mounting portion 25 of the support assembly 100 of the display device 1 to the back side of the back panel 200, the support assembly 100 can be assembled in a vertical position, improving assembly efficiency. It also facilitates after-sales maintenance and power-on debugging, eliminating the need to disassemble the base 30 during after-sales maintenance of the mainboard and power board.

[0057] Furthermore, by incorporating reinforcing ribs, the structural reliability of the back plate 200 can be improved. The mounting part 25 is connected to the reinforcing ribs, enabling a rigid connection between the support assembly 100 and the back plate 200, resulting in good installation stability.

[0058] In some embodiments, such as Figure 1As shown, the reinforcing ribs are multiple, including at least one first reinforcing rib 210 extending vertically and at least one second reinforcing rib 220 extending horizontally. The first reinforcing rib 210 and the second reinforcing rib 220 are connected. The mounting part 25 is connected to the first reinforcing rib 210 to further improve the structural reliability of the back plate 200. At the same time, it can further improve the rigidity of the connection between the support assembly 100 and the back plate 200. This connection method can provide stronger torsional resistance and stability, ensuring that the bracket 20 will not loosen or deform during use, and ensuring sufficient stability and rigidity when the display device 1 is upright on the desktop. For example, there are multiple second reinforcing ribs 220, with at least one located at the bottom of the back plate 200, serving as a basic reinforcement of the entire back plate 200. There are multiple first reinforcing ribs 210, including at least two first reinforcing ribs 210 located on the left and right sides of the back plate 200. The two ends of the two first reinforcing ribs 210 extend to the two ends of the vertical direction adjacent to the back plate 200, respectively. Some of the first reinforcing ribs 210 are located in the middle of the back plate 200 and connected to the second reinforcing ribs 220 located in the middle of the back plate 200.

[0059] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the back panel 200 includes a back panel body 230 and a decorative cover 240. The back panel body 230 has reinforcing ribs and is used to fix the display panel of the display device 1 to provide support and protection. The decorative cover 240 is used to mount accessories such as speakers. The decorative cover 240 is connected to the bottom of the back panel body 230. The mounting part 25 is connected to the decorative cover 240 and the reinforcing ribs to further improve the installation reliability of the support assembly 100. The bracket 20 has a protrusion 26 protruding toward the decorative cover 240, and the decorative cover 240 has a mating groove 240a in which the protrusion 26 is embedded. Thus, a connection and tight fit are achieved between the two. The decorative cover 240 can fully protect the bottom of the mounting part 25. In the event of an abnormal bare-machine drop to the ground, the protrusion 26 and the mating groove 240a can protect the mounting part 25 and offset the torque transmitted to the mounting part 25 when the display device 1 falls. The protrusion 26 and the decorative cover 240 can further disperse the force, avoiding damage to the connection between the reinforcing rib and the mounting part 25, and improving the drop resistance. In addition, this connection method can increase the stability and strength of the bracket 20, ensuring that the decorative cover 240 will not loosen or fall off.

[0060] Furthermore, referring to Figure 2 , Figure 3 , Figure 5 and Figure 7The display device 1 may include a plurality of second fasteners (not shown in the figure). The mounting part 25 has a plurality of first fixing holes 251 spaced apart in the vertical direction, and the reinforcing rib has a plurality of second fixing holes 250 spaced apart in the vertical direction. The plurality of first fixing holes 251 and the plurality of second fixing holes 250 are arranged one-to-one to allow the second fasteners to pass through, so as to realize the installation of the mounting part 25 and the reinforcing rib. The installation has good reliability and is easy to disassemble. For example, the second fasteners may be mechanical thread screws.

[0061] Furthermore, one of the mounting part 25 and the reinforcing rib has a second positioning hole 260, and the other of the mounting part 25 and the reinforcing rib has a second positioning post 252. The second positioning post 252 and the second positioning hole 260 are inserted into each other, thereby improving the installation efficiency and the stability of the fit between the back plate 200 and the support assembly 100.

[0062] In some embodiments, such as Figure 2 As shown, the reinforcing rib has multiple second positioning holes 260, which are spaced apart vertically. These multiple second positioning holes 260 and multiple second fixing holes 250 are alternately arranged vertically to maximize the spacing between adjacent fixing holes 250, thereby improving installation stability. One of the multiple second positioning holes 260 can be oblong, and another can be circular. This serves two purposes: it prevents mistaken identification, and the oblong shape reduces space requirements. Of course, the specific structure of the second positioning holes 260 can be customized according to actual conditions and is not limited here.

[0063] In some embodiments, such as Figure 5 As shown, the decorative cover 240 has a third fixing hole 240b. A portion of the first fixing hole 251 and a portion of the second fixing hole 250 are correspondingly provided with the third fixing hole 240b. The edge of the aforementioned portion of the second fixing hole 250 is provided with a flange 250a surrounding the second fixing hole 250. The flange 250a extends towards the third fixing hole 240b. The flange 250a can improve the structural reliability of the hole structure, thereby improving the installation reliability of the bracket 20 and the back plate 200. Furthermore, the flange 250a extending towards the third fixing hole 240b can make reasonable use of space, reducing the space occupied and facilitating the miniaturization design of the display device 1.

[0064] Of course, the other second fixing holes 250 and second positioning holes 260 may also be provided with flanges to improve structural strength and reliability, and improve assembly stability. The flanges of the second fixing holes 250 and the second positioning holes 260 may extend in a direction away from the mounting part 25 to facilitate assembly.

[0065] In some embodiments, such as Figure 2As shown, the sidewall of the mating groove 240a facing the back panel body 230 has a first inclined surface 240c, and the protrusion 26 has a second inclined surface 261. The first inclined surface 240c and the second inclined surface 261 are fitted together. By providing the first inclined surface 240c, the accessories inside the decorative cover 240 can be avoided, and the internal space of the decorative cover 240 and the back panel body 230 can be used reasonably. By fitting the first inclined surface 240c and the second inclined surface 261 together, the drop resistance of the display device 1 can be improved.

[0066] In some embodiments, combined with Figure 1 There are multiple mating grooves 240a, and the number of mating grooves 240a is greater than or equal to twice the number of support components 100. For example, the number of mating grooves 240a can be twice the number of support components 100, so that the support components 100 can be selectively installed at multiple positions on the back plate 200, thereby improving practicality.

[0067] In some embodiments, such as Figure 1 , Figure 5 As shown, the reinforcing rib has at least one fourth fixing hole 270 and at least one third positioning hole 280. A removable sealing film (not shown) is attached to the fourth fixing hole 270 and the third positioning hole 280. It is understood that the support assembly 100 is detachably mounted on the back plate 200. The support assembly 100 can be selectively installed in multiple mounting positions. Multiple mating grooves 240a are correspondingly provided to multiple mounting positions. The fourth fixing hole 270 and the third positioning hole 280 can be respectively positioned opposite to the first fixing hole 251 and the first positioning hole 33 to achieve their installation, and / or, the third fixing hole 240b and the second positioning hole 260 can be respectively positioned opposite to the first fixing hole 251 and the first positioning hole 33 to achieve their installation. Hole-like structures that do not mate with the first fixing hole 251 and the first positioning hole 33 are prone to dust accumulation or corrosion. By providing a sealing element, the hole-like structure can be sealed, improving the structural stability of the display device 1. For example, the sealing element can be a sealing sticker.

[0068] In some embodiments, such as Figure 1 As shown, there are multiple support components 100, which are spaced apart along the length of the display device 1. For example, there can be two support components 100, located at opposite ends of the length of the display device 1, to ensure the stability of the support components 100 in supporting the main body of the display device 1. That is, the display device 1 has multiple second fixing holes 250 along its length for mounting and engaging with the support components 100. For example, the multiple second fixing holes 250 can have different structures, such as different inner diameters or different shapes, or they can be located in different positions to prevent the multiple support components 100 from being installed backwards, thus achieving a foolproof function.
