Description

Technical Field

[0001] This utility model relates to the field of LED grid screen technology, and in particular to an LED grid screen display module. Background Technology

[0002] It is a new type of display screen technology that uses LED light strips to form an integrated display screen, creating a screen with strip-shaped, hollow, and light-transmitting characteristics. The LED grid screen not only retains the high brightness and high definition of traditional LED displays, but also achieves the effects of light transmission and ventilation through the hollow design, making the screen lighter and more beautiful.

[0003] However, current LED grid screen display modules have the following drawbacks:

[0004] Traditional LED grid screens mostly use a fixed frame structure, with the spacing between adjacent frames rigidly connected by bolts, which cannot be dynamically adjusted. For special scenarios such as curved curtain walls, it is necessary to customize irregularly shaped frames, which increases production costs and extends the installation period.

[0005] Secondly, existing light strips are mostly fixed by screws or clips. Replacing a single light strip requires professional tools and 5-8 minutes of operation time. In addition, the traditional wired power supply method requires opening a wire hole in the frame, resulting in a protection level of only IP54, which cannot meet the needs of outdoor high humidity environment.

[0006] Therefore, how to provide an LED grid screen display module is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] One objective of this invention is to propose an LED grid screen display module. This invention can achieve stepless spacing adjustment and multi-angle splicing of adjacent frames through the coordinated design of connecting components and magnetic wireless power supply interface, thus solving the problem that traditional fixed structures cannot adapt to curved surface installation.

[0008] An LED grid screen display module according to an embodiment of the present utility model includes a frame, a light strip, and a connecting component;

[0009] The frame has a longitudinally extending slot on the front side, and the light strip can be detachably inserted into the slot. There are multiple sets of frames, and each set of frames has threaded posts on the top and bottom sides.

[0010] The connecting assembly includes a connecting block and a sliding connecting plate, the connecting plate being sleeved on the threaded post and being able to slide along its axial direction;

[0011] Sleeves are symmetrically embedded on both sides of the top of the connecting block. Limiting pins are vertically inserted into the sleeves. Several sets of limiting holes are equidistantly opened on the top of the connecting plate. Limiting pins are inserted into the limiting holes for limiting. A fastening knob is screwed onto the top of the threaded column.

[0012] Magnetic blocks are embedded in the upper and lower sides of the inner wall of the slot, and metal plates for adsorption and fixation with the magnetic blocks are embedded in the upper and lower sides of the back of the light strip. The light strip can be fixed in the slot by the attraction of the metal plates and the magnetic blocks.

[0013] Furthermore, a transmitting coil is centrally embedded in the inner wall of the slot, and a receiving coil matching the transmitting coil is centrally embedded in the back of the light strip, and the transmitting coil and the receiving coil are in contact when the light strip is inserted into the slot.

[0014] Furthermore, a spring is fitted inside the sleeve and onto the limiting pin, with its upper and lower ends fixedly connected to the inner wall of the sleeve and the limiting pin, respectively.

[0015] Furthermore, the outer walls on both sides of the connecting plate and located within the connecting block are integrally formed with limiting blocks, which are used to prevent the connecting plate from falling off within the connecting block.

[0016] Furthermore, several groups of LED beads are embedded and installed on the outer surface of the light strip, and each group of LED beads is equidistantly distributed on the outer wall of the light strip.

[0017] Furthermore, the frame has mounting bases integrally formed on the rear sides of both the upper and lower ends, and the mounting bases are provided with mounting holes for fixing.

[0018] Furthermore, the number of frames is multiple sets, and the multiple sets of frames are interconnected by connecting blocks and connecting plates.

[0019] The beneficial effects of this utility model are:

[0020] 1. This utility model utilizes the sliding of the connecting plate within the connecting block and the cooperation of the spring pre-tightening limiting pin and the limiting hole to enable stepless adjustment of the spacing between adjacent frames within a certain range. In practical applications, when it is necessary to adjust the overall size of the display module to adapt to a specific wall surface, there is no need to replace the frame. By simply sliding the connecting plate and fixing it with the limiting pin, the spacing can be precisely adjusted, greatly improving the flexibility of installation. Furthermore, since the connecting plate can rotate freely around the threaded column, multiple frames can be spliced ​​into any angle of 0-120° according to the needs of the installation environment. This makes the display module not only suitable for flat installation but also easy to install on curved screens. It can adapt to arc structures with a minimum radius of 1.2m. During the installation of the curved screen, by rotating the connecting plate, the frames can be arranged according to the designed curvature, ensuring a smooth and natural curved effect for the entire display module.

[0021] 2. This utility model uses the metal plate on the back of the light strip to magnetically attract and fix it to the magnetic block in the frame slot. The installation time of a single light strip is short. In the actual installation process, you only need to align the light strip with the slot and gently insert it to complete the fixation. No tools are required, which greatly improves the installation efficiency. Secondly, when the light strip is inserted into the slot, the transmitting coil and the receiving coil are in contact and wireless power supply is achieved through electromagnetic coupling. This power supply method eliminates the cumbersome wiring problems caused by traditional hard wire connection and makes the installation of light strip more convenient. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] Example 1

[0033] refer to Figure 1-7 The LED grid screen display module in this embodiment mainly consists of a frame 1, a light strip 2, and connecting components;

[0034] Specifically, the frame 1, as the supporting structure of the entire module, is made of high-strength aluminum alloy. This material has the advantages of being lightweight, high-strength, and corrosion-resistant, which can ensure the stability and reliability of the module during long-term use. The front side of the frame 1 has a longitudinally extending slot 3 that matches the thickness and width of the light strip 2, ensuring that the light strip 2 can be inserted tightly and securely.

[0035] The LED strip 2 is the core light-emitting component of the display module. Several sets of LED beads 8 are embedded in its outer surface. These LED beads 8 are 5050 surface mount LEDs, which have the characteristics of high brightness, low power consumption and long life. The LED beads 8 are evenly distributed on the outer wall of the LED strip 2 with a spacing of 10mm. This layout can ensure the uniformity and clarity of the displayed image. Metal plates 6 are embedded in the upper and lower sides of the back of the LED strip 2. The metal plates 6 are made of 304 stainless steel and are 1mm thick. Magnetic blocks 4 are embedded in the upper and lower sides of the inner wall of the slot 3. The magnetic blocks 4 are neodymium iron boron strong magnets. When the LED strip 2 is inserted into the slot 3, the metal plates 6 and the magnetic blocks 4 generate a strong attraction force, thereby firmly fixing the LED strip 2 in the slot 3, realizing the function of quick installation and disassembly, which facilitates subsequent maintenance and replacement.

[0036] The frame 1 consists of multiple sets, with threaded posts 10 on both the top and bottom sides of each set. The connecting components include connecting blocks 11 and sliding connecting plates 12. The connecting blocks 11 are made of zinc alloy die casting, which has high strength and precision. The connecting plates 12 are made of 4mm thick cold-rolled steel plates, with limit blocks 18 integrally formed on both outer walls and inside the connecting blocks 11. Their function is to prevent the connecting plates 12 from falling out of the connecting blocks 11 and to ensure the stability of the connection.

[0037] The connecting plate 12 is sleeved on the threaded post 10 and can slide along its axial direction. Sleeves 14, made of brass, are symmetrically embedded on both sides of the top of the connecting block 11. Limiting pins 15, made of stainless steel, are vertically inserted into the sleeves 14. Springs 16, compression springs, are fitted inside the sleeves 14 and onto the limiting pins 15, with their upper and lower ends fixedly connected to the inner wall of the sleeves 14 and the limiting pins 15, respectively. Several sets of limiting holes 17 are equidistantly opened on the top of the connecting plate 12. When it is necessary to adjust the spacing between the frames 1, the limiting pins 17 are lifted. 5. When the spring 16 is compressed, the connecting plate 12 can slide freely. After reaching the target position, the limit pin 15 is released, and the spring 16 pushes the limit pin 15 into the corresponding limit hole 17 to achieve the limit function. The top of the threaded column 10 is screwed with a fastening knob 13. The fastening knob 13 is made of plastic and has anti-slip texture on the surface for easy operation. The connecting plate 12 can rotate freely around the threaded column 10, so multiple sets of frames 1 can be freely installed according to the required curvature. After tightening the fastening knob 13, the stability of the connection can be further enhanced to ensure that the connection between multiple sets of frames 1 is firm and reliable.

[0038] Secondly, the frame 1 has an integrally formed mounting base 9 at both the upper and lower rear ends. The mounting base 9 is made of die-cast aluminum and has high strength and precision. The mounting base 9 has mounting holes for fixing. This mounting hole design is compatible with universal curtain wall mounting systems, making it convenient to install the module on different support structures, such as walls and brackets.

[0039] In this embodiment, the LED grid screen display module is quickly installed, disassembled, and adjusted. The cooperation between the magnetic block 4 and the metal plate 6 ensures the stable installation of the light strip 2. The elastic limit of the connecting components and the double locking of the fastening knob 13 ensure the connection stability between the frames. The design of the mounting base 9 improves the versatility and environmental adaptability of the module.

[0040] Example 2

[0041] refer to Figure 2 and Figure 4 A transmitting coil 5 is embedded in the center of the inner wall of slot 3. The transmitting coil 5 is made of enameled wire with a diameter of 0.5mm. A receiving coil 7, which matches the transmitting coil 5, is embedded in the center of the back of the light strip 2. The receiving coil 7 is made of enameled wire with a diameter of 0.4mm. When the light strip 2 is inserted into the slot 3, the transmitting coil 5 and the receiving coil 7 are in close contact with each other, with the gap controlled within 0.5mm. The external power supply generates an alternating magnetic field through the transmitting coil 5. The receiving coil 7 induces an electromotive force in the alternating magnetic field, thereby powering the light strip 2. This wireless power supply method avoids the cumbersome wiring problems caused by traditional hard wire connections, and at the same time improves the waterproof performance and safety of the module.

[0042] It should be noted that, in order to improve the display effect, 45° inclined light guide plates can be set on both sides of slot 3. The light guide plates are made of PMMA material with a thickness of 2mm. The function of the light guide plates is to evenly diffuse the light emitted by LED beads 8 to form a uniform surface light emission effect. The light emission angle of LED beads 8 is 120°. Through the refraction and reflection of the light guide plates, the light can be more evenly distributed on the module surface. The measured illuminance uniformity is ≥90%, and the contrast ratio reaches 3000:1, which can present a clear and bright display picture.

[0043] The surface of the light strip 2 can be covered with a 3mm thick PC diffuser plate. The PC diffuser plate has good light transmittance and impact resistance, which can further diffuse the light and improve the softness and uniformity of the display image. At the same time, the PC diffuser plate is bonded to the frame 1 with silicone sealant. The silicone sealant has a Shore hardness of 25A, has good flexibility and sealing performance, and forms a complete protective layer, which can effectively prevent dust, moisture and other substances from entering the module and protect the internal electronic components from damage.

[0044] In this embodiment, the introduction of a wireless power supply system solves the problems caused by traditional wiring, improves the waterproof performance and safety of the module, and optimizes the display effect through the design of the light guide plate and diffuser plate, making the display image more uniform, clear and soft. The design of the protective layer enhances the environmental adaptability of the module and extends the service life of the module.

[0045] Example 3

[0046] refer to Figure 2 and Figure 4 The receiving coil 7 has a built-in wireless communication module that uses 2.4GHz frequency band wireless communication technology. It can transmit control signals synchronously with the transmitting coil 5. Each LED bead 8 integrates a temperature sensor with an accuracy of ±0.5℃, which can monitor the working temperature of the bead in real time. These temperature sensors are connected to the control system via CAN bus and feed the temperature data back to the control system in real time. When the temperature of a certain bead exceeds 65℃, the control system automatically reduces the driving current of the bead by 10% to reduce the temperature of the bead, protect the bead from damage, and extend the service life of the bead.

[0047] It is worth mentioning that if the power supply to a certain light strip 2 is interrupted, the adjacent light strip will maintain emergency display for 30 minutes through the redundant power supply circuit. The redundant power supply circuit consists of an energy storage capacitor bank with a capacity of 1000μF, which can provide sufficient power to the light strip in a short time to ensure the continuity of the display. The management software can accurately locate the fault location with an error of ≤50mm and generate a maintenance work order. By analyzing the data from the temperature sensor and the current sensor, the management software can determine the type of fault, such as damaged LED beads or abnormal power supply, and promptly notify maintenance personnel to carry out repairs.

[0048] Working principle: First, the connecting plates 12 on both sides of the connecting block 11 are respectively fitted onto the threaded posts 10 at the upper and lower ends of the two adjacent frames 1. After fitting, the fastening knob 13 can be rotated to fix it. Then, the limiting pin 15 can be pulled upwards, and the connecting plate 12 can slide laterally within the connecting block 11. At this time, the distance between the two adjacent frames 1 can be adjusted. After adjusting to a suitable distance, the limiting pin 15 can be released. At this time, the return of the spring 16 will push the limiting pin 15 into the corresponding limiting hole 17 to complete the limiting. Then, the mounting seats on the upper and lower sides of the frame 1 can be used to install each frame 1 onto the screen. On the screen bracket, since each set of connecting plates 12 can rotate around the threaded column 10, the angle of each set of frames 1 can be changed at will, so that multiple sets of frames 1 can be installed on the curved screen bracket, thus it is suitable for the installation of curved screens. After the frame 1 is installed, the light strip 2 can be inserted into the slot 3. At this time, the magnetic block 4 and the metal plate 6 can be attracted to each other to complete the fixation. At the same time, the transmitting coil 5 can contact the receiving coil 7 to achieve electrical connection. After that, the multiple sets of LED beads 8 on the light strip 2 will light up, and the LED beads 8 on the multiple sets of light strip 2 will be lit by the controller to display the image.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
