Technical Field
[0001] This invention relates to the field of transportation technology, specifically to a loading tool for an LED display device and the LED display device thereof. Background Technology
[0002] During the installation of existing LED display devices, it is usually necessary to first assemble all the LED display devices (also known as LED cabinets) into a complete screen before powering it on for testing. If quality problems such as uneven brightness, abnormal color, or circuit failure are found in some devices, the entire screen needs to be disassembled and replaced, which is not only time-consuming and labor-intensive, but also significantly increases manpower and time costs.
[0003] Currently, the industry commonly uses flight cases as the means of transporting and storing LED display devices, but there are obvious technical defects: First, the function is limited, only able to achieve packaging protection and transportation, and cannot perform pre-testing of LED display devices during transportation or storage, resulting in a delay in testing; Second, it lacks screen building assistance functions, requiring additional special brackets to be carried during on-site setup, resulting in a large number of devices, a large space occupation, and a cumbersome setup process.
[0004] Therefore, there is an urgent need for an integrated loading tool that combines transportation and storage, pre-inspection support, and rapid screen assembly functions to solve pain points such as delayed inspection, high rework rate, and complex equipment, and improve the installation and maintenance efficiency of LED displays.
[0005] Therefore, based on the above problems, it is necessary to make improvements. Summary of the Invention

[0031] Please see Figures 1 to 5 As shown, a loading tool for an LED display device includes a main frame for placing the LED display device 1 and at least one set of loading units disposed within the main frame;
[0032] The main frame includes a fixed frame 2 and a movable frame 3. The movable frame 3 is rotatably connected to the fixed frame 2, and the movable frame 3 and the fixed frame 2 are rotatably connected by a hinge (or pivot). The movable frame 3 can rotatably switch between a box structure and a support structure, so that when the movable frame 3 is rotated and snapped shut, it forms a closed box structure with the fixed frame 2 (e.g., ...). Figure 1 (As shown), used for the transportation and storage of LED display devices; when the movable frame 3 is rotated and unfolded, it forms a stable support structure with the fixed frame 2 (as shown). Figure 3 and Figure 5 As shown, it is used for on-site setup of LED display devices. When snapped together, it enables safe transportation and storage. When unfolded, it can be used directly as a screen mounting bracket. It can adapt to the setup needs of different sized displays, eliminating the need to carry additional special brackets and reducing the number of devices and space required.
[0033] The loading unit includes a slide rail 4 and a loading base 5 for connecting and fixing the LED display device. The slide rail 4 is fixedly installed inside the fixed frame 2. The loading unit is located along the lateral width direction of the fixed frame 2 (e.g., ...). Figure 1 and Figure 3 The LED display devices are evenly distributed in the vertical or longitudinal direction (as shown), so that the orientation of the loading unit can be set according to the actual needs of storing LED display devices horizontally or storing LED display devices vertically; one side or bottom of the loading seat 5 is slidably engaged with the slide rail 4 through a slider, so that the loading seat 5 carrying the LED display device can slide back and forth along the slide rail 4 to realize convenient loading and unloading of the LED display device;
[0034] The mounting base 5 is provided with a first connector interface 6 (i.e., male or female socket) for electrical connection with the LED display device, which is used to provide stable power supply to the LED display device (how to supply power is conventional technology in the field and will not be described in detail), and to support the rapid start-up of its own built-in testing function during transportation or storage.
[0035] like Figure 1 and Figure 3 As shown, the top of the fixed frame 2 and the top of the movable frame 3 are respectively provided with first locking members 7 that can be interlocked and fixed together. Figure 1 and Figure 3 To facilitate understanding of the installation position of the first locking component 7 on the fixed frame and the movable frame, the specific structure of the first locking component 7 is not shown, only the specific installation position is indicated. The first locking component 7 is a conventional locking component in the art. The first locking component 7 is a locking component composed of male and female buckles, such as a butterfly lock. The top of the fixed frame 2 is provided with two symmetrically distributed male buckles, and the top of the movable frame 3 is provided with a female buckle that matches the male buckles. When the movable frame 3 is rotated and unfolded to a preset angle, the movable frame 3 is perpendicular to the fixed frame 2. The female buckle of the movable frame 3 and the male buckle of the fixed frame 2 are engaged and fixed to each other, ensuring the stability of the support structure.
[0036] like Figure 1 As shown, the connecting sides of the fixed frame 2 and the movable frame 3 are respectively provided with second locking members 8 that can be interlocked and fixed together. Figure 1 and Figure 3 To facilitate understanding of the installation position of the second locking element 8 on the fixed frame and the movable frame, the specific structure of the second locking element 8 is not shown, only the specific installation position is indicated. The second locking element 8 is a conventional locking element in the art. The second locking element 8 is also a locking element composed of male and female buckles, such as a butterfly lock. When the movable frame 3 is rotated and fastened to form the box structure, the second locking element 8 achieves a tight fastening between the fixed frame 2 and the movable frame 3, realizing the closed and fixed box structure and preventing the movable frame 3 from being accidentally opened during transportation.
[0037] like Figure 4As shown, the back of the fixed frame 2 is detachably provided with a mounting bracket, which consists of at least one or more mounting bases 9. As shown in the figure, the mounting bracket consists of at least two long strip-shaped mounting bases 9, which are detachably connected to the back of the fixed frame 2 by screw fasteners, etc. The two mounting bases 9 are symmetrically distributed on both sides of the fixed frame 2. The mounting base 9 is provided with a second connector interface for electrical connection with the LED display device. When it is necessary to assemble a larger screen, it can be used as an extension screen structure to extend the LED display device based on the mounting bracket, thereby adapting to the assembly requirements of a larger screen, and at the same time providing an additional power supply interface for the LED display device.
[0038] like Figure 3 and Figure 4 As shown, the fixed frame 2 is provided with a positioning track 10 for fixing the LED display device above the loading seat 5. The positioning track 10 is a U-shaped groove structure, which is fixed inside the fixed frame 2 and located above each loading unit. One end of the positioning track 10 is provided with an opening for inserting the LED display device. Guide plates 11 are symmetrically provided on both sides of the opening. The guide plates 11 on both sides are inclined outward in a figure-eight shape, which facilitates the LED display device to be quickly aligned and inserted into the positioning track 10, thereby improving the installation and positioning efficiency.
[0039] like Figure 1 and Figure 2 As shown, both the fixed frame 2 and the movable frame 3 are hollow frames with a number of hollow holes distributed on them. This reduces the overall weight of the tool while ensuring structural strength, and at the same time achieves ventilation and heat dissipation, preventing the LED display device from malfunctioning due to poor heat dissipation during storage or testing.
[0040] like Figure 1 As shown, the fixed frame 2 has a relief groove on the side facing the movable frame 3 to prevent hand pinching. During the rotation and locking or unfolding of the movable frame 3, the operator's hand is prevented from being pinched by the gap between the frames, thus improving the safety of use.
[0041] like Figure 3 As shown, the inner side of the movable frame 3 is provided with anti-collision sponge. When the movable frame 3 is fastened, the anti-collision sponge is attached to the LED display device to buffer the impact of bumps during transportation and prevent damage to the display panel of the LED display device.
[0042] The present invention also provides an LED display device, including a loading tool for the LED display device described in any of the above technical solutions. The LED display device includes a display panel and a frame. The display panel is fixedly disposed on the front side of the frame. The frame is provided with an adapter interface that matches the connector interface on the loading seat 5. The adapter interface is plugged and plugged into the first connector interface 6 to realize power transmission and provide power support for its own testing function.
[0043] Furthermore, the LED display device has a built-in test function module, including a test trigger and a color display control unit (how the color display control unit controls the display panel to display colors is a conventional technique in the field and will not be described in detail here). The test trigger is a push-button located on the side of the mounting frame. When pressed, it triggers the color display control unit to drive the display panel to display red, green, blue, and white test signals in sequence (each color is displayed for 3 seconds, automatically cycling). By observing the four-color display status, the operator can quickly determine whether the display panel has quality problems such as uneven brightness, abnormal color, or damaged pixels.
[0044] Preferably, at least one side of the mounting frame is fixedly connected to the loading seat 5 by a screw fastener. Specifically, the bottom of the mounting frame is provided with a threaded hole, and the loading seat 5 is provided with a through hole at the corresponding position. The screw fastener passes through the through hole and is threadedly connected to the threaded hole, so as to firmly fix the LED display device on the loading seat 5 and prevent it from sliding and colliding during transportation.
[0045] like Figure 1 and Figure 3 As shown, the bottom four corners of the fixed frame 2 are fixed with four casters by bolts. The casters are made of silent rubber wheels and are equipped with a foot-operated brake locking component. When pushing the loading tool, it can turn flexibly. After reaching the designated position, stepping on the brake component will fix it, which is convenient for transportation and on-site positioning.
[0046] The usage process of the loading tool of the present invention under different usage states is as follows:
[0047] Transport and storage status (e.g.) Figure 1 As shown, the internal LED display device is hidden for easy observation: Place the LED display device on the loading seat 5, connect the adapter interface to the first connector interface 6, and fix it with screw fasteners; push the loading seat 5 to push it into the fixed frame 2 along the slide rail 4, and guide it into the positioning rail 10 through the guide piece 11 of the positioning rail 10; then rotate the movable frame 3 to the snap-fit state, and fix it by the male and female snap-fits, forming a closed box structure. The loading tool is then pushed by the bottom casters for transportation or storage.
[0048] Pre-detection status (e.g.) Figure 3(As shown): After being transported to the site, the LED display device does not need to be disassembled. The movable frame 3 is rotated and unfolded, the loading seat 5 is pulled out, and power is supplied through the connector interface. The test trigger of the LED display device is pressed, and the display board displays four-color test signals in a cycle. The staff checks the quality of each LED display device one by one, checks out unqualified products and replaces them in time to avoid rework after subsequent assembly.
[0049] Screen mounting status (e.g.) Figure 5 As shown): The qualified LED display device is removed from the mounting base 5 and assembled using the support structure formed by the rotating and unfolding movable frame 3 and the fixed frame 2. The assembly support is installed on the back of the fixed frame 2, and the LED display device is fixed on the mounting base 9. Power is supplied by plugging in the adapter interface of the LED display device through the second connector interface on the mounting base 9. The LED display device is also equipped with male and female sockets for interconnection and power transmission, realizing the splicing of multiple LED display devices and completing the rapid screen assembly.
[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
