[0001] This application belongs to the technical field of displays, and more specifically, relates to a display screen box frame structure and an LED display device. Background Art

[0002] In the technical field of LED display screens, the frame box structure, as the basic support unit of the display screen, its structural strength is directly related to the performance, safety and service life of the entire display screen. However, the frame boxes of LED display screens widely used in the current market generally have the problem of insufficient structural strength, which has become a bottleneck restricting the further development of LED display screen technology. Summary of the Utility Model

[0003] The purpose of the embodiments of this application is to provide a display screen box frame structure and an LED display device to solve the technical problem of insufficient structural strength of the frame box structure in the prior art.

[0004] To achieve the above purpose, the technical solution adopted in this application is:

[0005] Provide a display screen box frame structure, including:

[0006] Multiple connecting rod groups, each connecting rod group includes at least two connecting rods; each of the connecting rod groups encloses a connecting frame in sequence; by increasing the number of connecting rods, the bending and torsional resistance of the connecting rod group can be enhanced, thereby improving the structural strength of the connecting rod group;

[0007] Multiple corner blocks, the corner blocks are connected to one end of each connecting rod group in the extending direction, and each of the corner blocks is located at each vertex of the connecting frame. The connecting rod group and the corner blocks together constitute the display screen box frame structure of this application.

[0008] As a further improvement of the above technical solution:

[0009] Optionally, the display screen cabinet frame structure further includes a double-headed zipper which is arranged on the connecting rod group and used for locking connection with an adjacent display screen cabinet frame structure. The double-headed zipper includes a handle, a lock body, a first lock head, a second lock head and a lock piece. The handle is installed on the lock body and located at one end of the lock body. The first lock head and the second lock head are installed on the lock body at intervals and located at the other end of the lock body. The handle is used to drive the first lock head and the second lock head to act. The lock body is installed on the connecting rod group at the upper edge. The first lock head and the second lock head are used for locking connection with the lock piece on an adjacent display screen cabinet frame structure. The lock piece is installed on the connecting rod group at the lower edge and is used for locking connection with the first lock head and the second lock head on an adjacent display screen cabinet frame structure. The first lock head and the second lock head are installed on the lock body at intervals, which increases the distance between the two locking points. Therefore, when the two cabinet frame structures are locked and connected, it is not easy to rotate around a single locking point, making the connection between the two cabinet frame structures more stable.

[0010] Optionally, the display screen cabinet frame structure further includes an arc lock which is arranged on the corner block and used for locking connection with an adjacent display screen cabinet frame structure. The arc lock includes an arc lock body and a pull pin. The arc lock bodies are arranged in pairs and are respectively movably installed on the two corner blocks on the right side edge / left side edge. The pull pin is arranged corresponding to the arc lock body and is installed on the two corner blocks on the left side edge / right side edge. The arc lock body includes a lock hole and a plurality of mounting surfaces with different inclination angles. When the arc lock body is locked and connected with the pull pin on an adjacent display screen cabinet frame structure, the pull pin extends into the lock hole of the arc lock body, and the corner block on the adjacent display screen cabinet frame structure abuts against the corresponding mounting surface. This arc lock can realize the assembly and construction of an arc screen.

[0011] Optionally, the display screen cabinet frame structure further includes a support block located between the two corner blocks, and the connecting rod is inserted into the support block. The support block adds a support point to the connecting rod and reduces the overhanging distance of the connecting rod. Therefore, it can effectively reduce the bending deformation of the connecting rod and enhance the bending resistance of the connecting rod.

[0012] Optionally, the connecting rods in the connecting rod group are arranged at intervals from each other. Since there are gaps between the connecting rods, it can not only reduce air resistance and facilitate air circulation, thus contributing to the heat dissipation of the LED module, but also the gaps between the connecting rods can serve as positions for operators to grasp when carrying, making the connecting rods act as handles and facilitating loading and unloading.

[0013] Optionally, the connecting rod is a carbon fiber connecting rod. Compared with a connecting rod made of traditional metal materials, the carbon fiber connecting rod can reduce the overall weight while maintaining the same or higher strength level.

[0015] LED modules;

[0016] The above-mentioned display screen box frame structure, installed on the back side of the LED module;

[0017] A control box, installed on the back side of the LED module.

[0018] Since this LED display screen includes the above-mentioned display screen box frame structure, therefore, it also has the advantages of the above-mentioned display screen box frame structure.

[0019] As a further improvement of the above technical solution:

[0020] Optionally, the LED module includes a mask, a lamp board, a metal bracket, and a bottom case that are stacked in sequence. The display screen box frame structure and the control box are both installed on the bottom case. The metal bracket can help the lamp board and the bottom case improve their own structural strength and flatness.

[0021] Optionally, the lamp board includes a first lamp board and a second lamp board respectively arranged in the left and right display areas. The first lamp board and the second lamp board are respectively signal-connected to the control box. Since the wiring between the first lamp board and the second lamp board is completely independent and does not interfere with each other, it can avoid the signal attenuation problem that may be caused by traditional long-distance wiring, which is beneficial to ensuring the display effect of the LED module.

[0022] Optionally, the bottom case further includes a corner protection structure. A receiving groove is provided at the top corner of the bottom case, and the corner protection structure is arranged in the receiving groove; the corner protection structure includes a base and a corner brace, and the corner brace is hinged to the base to expand or retract the corner brace. When handling or storing the LED display screen of the present application, the corner brace is in an expanded state and extends outside the top corner of the bottom case, so as to effectively protect the top corner of the bottom case from external impact and wear, thereby extending the service life of the product. When splicing and assembling the LED display screen of the present application, the corner brace is in a retracted state and retracts into the receiving groove, so as to avoid interference with adjacent LED display screens and achieve seamless splicing of the LED display screen.

[0023] The beneficial effects of the display screen box frame structure and the LED display device provided by the present application are as follows:

[0024] The display screen box frame structure provided by the present application includes a plurality of connecting rod groups and a plurality of corner blocks.

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following further describes this application in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0041] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0042] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application.

[0043] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0044] Such as Figure 1 and Figure 2As shown, the present application provides a display screen box frame structure, including a plurality of connecting rod groups and a plurality of corner blocks 2. Each connecting rod group includes at least two connecting rods 1, and the connecting rod groups are sequentially enclosed to form a connecting frame. By increasing the number of connecting rods 1, the bending and torsional resistance of the connecting rod group can be enhanced, thereby improving the structural strength of the connecting rod group.

[0045] The corner blocks 2 serve as the installation bases of the respective connecting rod groups and are connected to one end of the respective connecting rod groups in the extending direction. Each of the corner blocks 2 is located at each vertex angle of the connecting frame, and the display screen box frame structure of the present application is formed integrally by the connecting rod groups and the corner blocks 2. When installing this display screen box frame structure, it is necessary to connect each corner block 2 to the LED module 6.

[0046] As Figure 1 and Figure 2 shown, in an embodiment of the present application, the connecting rods 1 in the connecting rod group are arranged at intervals from each other. Since there are gaps between the connecting rods 1, not only can the air resistance be reduced, facilitating air circulation, which is helpful for the heat dissipation of the LED module 6, but the gaps between the connecting rods 1 can also serve as positions for an operator to grasp when carrying, enabling the connecting rods 1 to act as handles, facilitating handling and unloading.

[0047] In an embodiment of the present application, the connecting rod 1 and the corner block 2 are detachably connected. Specifically, the connecting rod 1 and the corner block 2 are detachably connected through connection methods such as plugging, threaded connection, and snap connection, so as to facilitate the disassembly and assembly of the connecting rod 1 and the corner block 2.

[0048] In an embodiment of the present application, a carbon fiber material is used to construct the connecting rod 1 to enhance the portability and durability of the display screen box frame structure. Compared with traditional metal materials, the carbon fiber connecting rod significantly reduces the overall weight while maintaining the same or higher strength level. In addition, carbon fiber also has excellent corrosion resistance and fatigue resistance, and can maintain stable structural integrity and functionality for a long time under harsh environmental conditions, extending the service life of the product.

[0049] As Figure 1 and Figure 2 shown, in an embodiment of the present application, it further includes a support block 5 located between two corner blocks 2, and the connecting rod 1 is plugged on the support block 5. The support block 5 adds a support point for the connecting rod 1 and reduces the overhanging distance of the connecting rod 1. Therefore, it can effectively reduce the bending deformation of the connecting rod 1 and enhance the bending resistance of the connecting rod 1.

[0050] As Figure 1 and Figure 3As shown, in an embodiment of the present application, the display screen cabinet frame structure provided by the present application further includes a double-headed zipper 3. The double-headed zipper 3 is arranged on the connecting rod group and is used for locking connection with adjacent display screen cabinet frame structures; specifically, the double-headed zipper 3 can be used for locking connection with the left and right adjacent display screen cabinet frame structures, or with the upper and lower adjacent display screen cabinet frame structures.

[0051] The double-headed zipper 3 includes a handle 31, a lock body 32, a first lock head 33, a second lock head 34, and a lock piece 35. Among them, the handle 31 is an operating component for the installer to operate the double-headed zipper 3. It is installed on the lock body 32 and is located at one end of the lock body 32 facing the inner side of the cabinet frame structure. The first lock head 33 and the second lock head 34 are located at the other end of the lock body 32. Through the connection of the lock body 32, the first lock head 33 and the second lock head 34 are in transmission with the handle 31. By rotating the handle 31, the lock body 32 is driven to drive the first lock head 33 and the second lock head 34 to move, so that the first lock head 33 and the second lock head 34 are switched between the locked state and the unlocked state. The lock body 32 adopts an existing double-headed linkage lock body, and its internal structure will not be described in detail.

[0052] In the setting manner of the first lock head 33 and the second lock head 34, the first lock head 33 and the second lock head 34 are installed on the lock body 32 at intervals. Since the distance between the first lock head 33 and the second lock head 34 is increased, that is, the distance between the two locking points is increased, when the two cabinet frame structures are locked and connected, it is not easy to rotate around a single locking point, so that the connection between the two cabinet frame structures is more stable.

[0053] To achieve the locking connection, the first lock head 33 and the second lock head 34 also need to be inserted into the lock piece 35, and the locking is formed through the form and position cooperation with the lock piece 35. In the specific arrangement manner of the lock piece 35, when the lock body 32, the first lock head 33, and the second lock head 34 are installed on the connecting rod group on the upper edge, the lock piece 35 is installed on the connecting rod group on the lower edge; conversely, if the lock body 32, the first lock head 33, and the second lock head 34 are installed on the connecting rod group on the lower edge, the lock piece 35 is installed on the connecting rod group on the upper edge. This arrangement method is also applicable to the double-headed zipper 3 arranged on the left connecting rod group and the right connecting rod group.

[0054] When a cabinet frame structure is spliced with another cabinet frame structure, the first lock head 33 and the second lock head 34 on one cabinet frame structure are inserted into the lock piece 35 on the other cabinet frame structure, and then the handle 31 is rotated to switch the first lock head 33 and the second lock head 34 from the unlocked state to the locked state, completing the splicing of the two cabinet frame structures.

[0055] To enable the display screen cabinet frame structure provided by the present application to realize the assembly and construction of an arc screen, such as Figure 1 and Figure 4As shown, in an embodiment of the present application, the display screen box frame structure provided by the present application further includes an arc lock 4.

[0056] The arc lock 4 is arranged on the corner block 2 and is used for locking and connecting with an adjacent display screen box frame structure; under the connection of the arc lock 4, two adjacent display screen box frame structures can be arranged at a certain angle, so as to be spliced one by one into a display screen with an approximate arc surface.

[0057] The arc lock 4 includes an arc lock body 41 and a pull pin 42. Specifically, the arc lock bodies 41 are arranged in pairs on two corner blocks 2 on the right side edge / left side edge. The arc lock body 41 includes a lock hole (not shown in the figure) and a plurality of mounting surfaces with different inclination angles, and the mounting surfaces are arranged in a stepped manner on the arc lock body 41 in sequence. When splicing the display screen box frame structure, the adjacent display screen box frame structures are supported on the mounting surfaces at corresponding angles, so that the two display screen box frame structures can be arranged at corresponding angles. Then, the pull pin 42 extends into the lock hole of the adjacent display screen box frame structure, and the locking connection is realized through the form-fit between the pull pin 42 and the lock hole. To facilitate adjusting the splicing angle of the two display screen box frame structures, the arc lock body 41 is movably installed on two corner blocks 2 on the right side edge / left side edge. When the splicing angle needs to be adjusted, the arc lock body 41 is moved so that the mounting surface at the corresponding angle abuts against the adjacent display screen box frame structure. Since the arc lock 4 adopts an existing arc lock, other specific structures of the arc lock will not be described in detail.

[0058] As Figure 5 and Figure 6 shown, the present application also provides an LED display screen, which includes an LED module 6, the display screen box frame structure in the above embodiment, and a control box 7.

[0059] Among them, the LED module 6 is the main functional component for displaying images, and both the display screen box frame structure and the control box 7 are installed on the back side of the LED module 6. The control box 7 controls the LED module 6 through signal connection. The control box 7 internally integrates functional circuits including but not limited to a driving circuit, a signal processing circuit, etc. Through these circuits, the stable transmission, processing, and display of image signals are ensured.

[0060] Since this LED display screen includes the display screen box frame structure in the above embodiment, it also has the advantages of the display screen box frame structure in the above embodiment.

[0061] As Figure 7 and Figure 8 shown, in an embodiment of the present application, the LED module 6 includes a mask 61, a lamp board, a metal bracket 64, and a bottom case 65 that are stacked in sequence.

[0062] Among them, the mask 61 is used to protect the light-emitting elements on the light board, and it covers the surface of the light board. The display screen box frame structure and the control box 7 are both installed on the bottom case 65. The size of the bottom case 65 can be specifically 500mm X 500mm. To improve the strength and flatness of the light board and the bottom case 65, a metal bracket 64 is installed on the bottom case 65. The metal bracket 64 is arranged between the light board and the bottom case 65, and the metal bracket 64 is installed on the bottom case 65 through fasteners such as screws. The metal bracket 64 is specifically made of drawn aluminum, which has the advantages of high strength and light weight. Since the metal bracket 64 itself has good structural strength and flatness, the metal bracket 64 can help the light board and the bottom case 65 improve their own structural strength and flatness.

[0063] Considering the benefits of actual production and processing, such as Figure 9 As shown, in an embodiment of the present application, four metal brackets 64 jointly support between the light board and the bottom case 65, which not only avoids the high cost of opening a large integral mold, but also can reduce the supporting area of the metal bracket 64 and reduce the deformation of the metal bracket 64, so as to better support the light board and the bottom case 65.

[0064] Such as Figure 10 As shown, in an embodiment of the present application, the light board includes a first light board 62 and a second light board 63 respectively arranged in the left and right display areas, and the first light board 62 and the second light board 63 are respectively signal-connected to the control box 7. Since the wiring between the first light board 62 and the second light board 63 is completely independent and does not interfere with each other, the problem of signal attenuation that may be caused by traditional long-distance wiring can be avoided, which is beneficial to ensuring the display effect of the LED module 6.

[0065] Such as Figure 5 、 Figure 7 And Figure 11 As shown, in an embodiment of the present application, the bottom case 65 further includes a corner protection structure. Specifically, a receiving groove 651 is provided at the top corner of the bottom case 65, and the receiving groove 651 is used to receive the base 652 and the corner brace 653 in the corner protection structure. The base 652 is installed on the receiving groove 651, and the corner brace 653 is hinged to the base 652. The corner brace 653 has a deployed state and a retracted state. When handling or storing the LED display screen of the present application, the corner brace 653 is in the deployed state and extends outside the top corner of the bottom case 65, so as to effectively protect the top corner of the bottom case 65 from external impact and wear, thereby extending the service life of the product. When splicing and assembling the LED display screen of the present application, the corner brace 653 is in the retracted state and retracts into the receiving groove 651, so as to avoid interference with adjacent LED display screens and achieve seamless splicing of the LED display screens.

[0066] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included within the protection scope of the present application.
