Description

Technical Field

[0001] This application belongs to the field of LED display equipment technology, and more specifically, relates to an LED display screen mounting structure and an LED display device. Background Technology

[0002] The LED display technology industry is currently experiencing rapid development, with application scenarios constantly expanding, ranging from indoor advertising displays and stage performances to commercial displays. As market competition intensifies, users are placing higher demands on the performance, reliability, and cost of LED displays. Currently, LED displays often employ magnetic structures for lamp assembly and maintenance, but this has significant shortcomings in daily use. Magnetic attraction causes dust to accumulate on the lamp surface, affecting the viewing experience and, in severe cases, leading to short circuits between lamps. This problem arises from magnetic leakage in the magnetic cover. On one hand, installation tools can leave hidden dangers at the notches in the magnetic cover; on the other hand, selecting magnets that are too large can cause magnetic leakage, making the magnetic structure prone to dust accumulation. This is currently a weakness of magnetic solutions for LED displays. Utility Model Content

[0003] The purpose of this application is to provide an LED display installation structure and an LED display device to solve the problem of magnetic leakage in the existing display installation structure that uses magnetic attraction.

[0004] To achieve the above objectives, according to one aspect of this application, an LED display installation structure and an LED display device are provided for connecting a display screen and a cabinet. The display screen has a ferromagnetic portion. The LED display installation structure includes: a mounting portion mounted on the cabinet, the mounting portion being positioned corresponding to the ferromagnetic portion, and a mounting groove provided on the mounting portion, the mounting groove forming a mounting opening at the end of the mounting portion away from the cabinet; and a magnet portion mounted within the mounting groove, the magnet portion not protruding from the mounting opening, the magnet portion attracting the ferromagnetic portion to connect the display screen to the cabinet, wherein the mounting opening is sealed by the ferromagnetic portion.

[0005] Optionally, the mounting part includes a main body and a first connecting structure. The mounting slot is disposed within the main body, and the first connecting structure is disposed at the end of the main body furthest from the mounting opening. The mounting part is connected to the cabinet through the first connecting structure. The mounting slot built into the main body provides a stable mounting space for the magnet. Combined with the secure connection between the main body and the cabinet at the end furthest from the mounting opening by the first connecting structure, this not only ensures the fixed position of the magnet and reduces displacement and loosening caused by external forces, but also avoids the risk of display abnormalities caused by loose connections by dispersing the gravity of the display screen and external forces, greatly enhancing the installation stability.

[0006] Optionally, a magnetically shielded thickened structure is provided around the outer periphery of the mounting section. Magnetic materials have a guiding and confining effect on magnetic fields. As the material thickness increases, its magnetic resistance decreases, making it easier for the magnetic field to conduct within the material rather than dissipating into the external space.

[0007] Optionally, the magnetic shielding thickened structure is fitted onto the outside of the main body, or is integrally formed with the main body.

[0008] Optionally, the first connection structure is a threaded connection structure, and a first control structure is provided on the side of the mounting part. Using simple mechanical forms such as straight-handle screwing or knobs avoids complex transmission components or electronic devices, allowing operators to more easily drive the studs into or out of the threaded holes in the housing. This greatly improves the convenience, controllability, and efficiency of the installation process, effectively reducing the operational threshold and installation cost, and is suitable for installation scenarios of various LED displays, from small indoor displays to large outdoor displays.

[0009] Optionally, the first connection structure is a threaded connection structure, and a second control structure is provided on the inner side of the mounting groove.

[0010] Optionally, the first control structure and / or the second control structure are multi-faceted control structures.

[0011] Optionally, the end face of the main body near the display screen abuts against the ferromagnetic part.

[0012] Optionally, an annular protrusion is provided on the side of the main body near the display screen, and a positioning recess is formed inside the annular protrusion. An installation port is formed at the bottom of the positioning recess, and the ferromagnetic part is adapted to the positioning recess and installed in the positioning recess.

[0013] Optionally, the magnet is adapted to the second control structure.

[0014] According to another aspect of this application, an LED display device is provided, which includes a display screen and a housing. The display screen is provided with a ferromagnetic part. The LED display device also includes a plurality of LED display screen mounting structures, which are spaced apart. The LED display screen mounting structures are the aforementioned LED display screen mounting structures.

[0015] The beneficial effects of the LED display installation structure provided in this application are as follows: Compared with the prior art, the magnet is installed in the mounting groove and does not protrude from the mounting opening, while the mounting opening is sealed by the ferromagnetic part, effectively reducing magnetic leakage of the magnet. With reduced magnetic leakage, the problem of dust adsorption on the LED display surface caused by magnetic attraction is significantly improved, effectively preventing dust from adhering to the lamp surface and affecting the viewing effect, maintaining a clear display image, and enhancing the user's visual experience. Because the large amount of dust adsorption caused by magnetic leakage from the magnet cover is avoided, the occurrence of short circuits between lamps due to dust accumulation is reduced, ensuring the normal and stable operation of the LED display, improving the safety of equipment use, and reducing equipment failures and safety hazards caused by short circuits. Reducing dust adsorption and short circuit problems means a lower frequency of display failures. Routine maintenance mainly focuses on routine inspections, eliminating the need for frequent cleaning of magnetically adsorbed dust or handling of short circuit faults, effectively simplifying the maintenance process. At the same time, it reduces the manpower and material costs incurred in fault repair, extends the service life of the LED display, and improves the cost-effectiveness of the equipment.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] As described in the background section, the LED display technology industry is currently experiencing rapid development, with application scenarios constantly expanding, ranging from indoor advertising displays and stage performances to commercial displays. With increasingly fierce market competition, users are placing higher demands on the performance, reliability, and cost of LED displays. Currently, LED displays often employ magnetic structures for lamp panel assembly and maintenance, but this has significant shortcomings in daily use. Magnetic attraction causes dust to adhere to the lamp surface, affecting the viewing experience and, in severe cases, leading to short circuits between lamps. This problem arises from magnetic leakage in the magnetic cover. On one hand, installation tools can leave hidden dangers at the two notches in the magnetic cover; on the other hand, selecting magnets that are too large can cause magnetic leakage, making the magnetic structure prone to dust accumulation. This is currently a weakness of magnetic solutions for LED displays.

[0037] To solve the above problem, see Figures 1 to 9 As shown in the embodiment of this application, the LED display installation structure is used for connecting the display screen 10 and the cabinet 20. The display screen 10 is provided with a ferromagnetic part 11. The LED display installation structure includes a mounting part 30 and a magnet part 40. The mounting part 30 is mounted on the cabinet, and its position corresponds to the position of the ferromagnetic part 11. The mounting part 30 is provided with a mounting groove 31, and the mounting groove 31 forms a mounting opening 311 at the end of the mounting part 30 away from the cabinet. The magnet part 40 is mounted in the mounting groove 31 and does not protrude from the mounting opening 311. The magnet part 40 attracts the ferromagnetic part 11, thereby connecting the display screen to the cabinet. The mounting opening 311 is sealed by the ferromagnetic part 11. In the field of LED display technology, this installation structure involves several key concepts. LED displays, or Light Emitting Diode displays, consist of numerous light-emitting diodes forming pixels. By controlling the brightness and color changes of these diodes, images and videos are displayed. They are widely used in advertising displays, stage performances, and other fields, and are the main, fixed components in installation structures. However, while this application primarily focuses on LEDs, it can also be extended to display installation structures using other display principles, and is not limited to LEDs.

[0038] Traditional LED displays often use a magnetic structure for assembling and maintaining the light panel and the cabinet. This structure uses the magnetic force of magnets to connect components, which is convenient to operate but suffers from magnetic leakage, attracting dust and causing short circuits. This mounting structure optimizes the magnetic structure. The ferromagnetic part 11 is a ferromagnetic component that is strongly attracted by magnets. Therefore, it is placed on the display screen and attracts the magnet part 40 on the mounting part 30, thereby achieving a stable connection between the display screen and the cabinet.

[0039] The mounting part 30, serving as the component for mounting the LED display screen onto the cabinet, is installed on the cabinet and its position corresponds to the ferromagnetic part 11 on the display screen. It also features a mounting groove 31. The mounting groove 31 is a recessed structure formed in the mounting part 30 to accommodate the magnet part 40. One end of the groove forms a mounting opening 311. The magnet part 40 is installed within the groove without protruding from the mounting opening 311. This not only limits and protects the magnet part 40 but also helps to seal the mounting opening 311 with the ferromagnetic part 11, effectively reducing magnetic leakage. The magnet part 40 can be fixed in the mounting groove 31 by adhesive, snap-fit, or other methods. Magnetic leakage refers to the leakage of the magnetic field generated by the magnet into the surrounding space. In traditional magnetic attraction structures, magnetic leakage causes the magnetic field to act on the surface of the display screen lamps, attracting dust and affecting the display screen's performance. This mounting structure, through optimized installation of the magnet part 40, reduces magnetic leakage. In LED displays, if dust accumulates due to magnetic leakage, it may create conductive paths between different lamps, leading to short circuits, affecting the normal operation of the display, or even causing equipment damage. The optimized installation structure reduces such risks.

[0040] The magnet part 40 is installed within the mounting groove 31 and does not protrude from the mounting opening 311. Simultaneously, the mounting opening 311 is sealed by the ferromagnetic part 11, effectively reducing magnetic leakage from the magnet part 40. With reduced magnetic leakage, the problem of dust adsorption on the LED display surface caused by magnetic attraction is significantly improved, effectively preventing dust from adhering to the lamp surface and affecting the viewing effect, maintaining a clear display image, and enhancing the user's visual experience. By avoiding the large amount of dust adsorption caused by magnetic leakage from the magnet cover, the occurrence of short circuits between lamps due to dust accumulation is reduced, ensuring the normal and stable operation of the LED display, improving equipment safety, and reducing equipment failures and safety hazards caused by short circuits. Reduced dust adsorption and short circuit problems mean a lower frequency of display failures. Routine maintenance mainly focuses on routine inspections, eliminating the need for frequent cleaning of magnetically adsorbed dust or handling of short circuit faults, effectively simplifying the maintenance process. At the same time, it reduces the manpower and material costs incurred in fault repair, extends the lifespan of the LED display, and improves the cost-effectiveness of the equipment.

[0041] The mounting part 30 in this embodiment includes a main body 33 and a first connecting structure 34. A mounting groove 31 is disposed within the main body 33, and the first connecting structure 34 is located at the end of the main body 33 furthest from the mounting opening 311. The mounting part 30 is connected to the housing via the first connecting structure 34. The mounting groove 31, built into the main body 33, provides a stable mounting space for the magnet part 40. Combined with the secure connection of the first connecting structure 34 between the main body 33 and the housing at the end furthest from the mounting opening 311, this not only ensures the magnet part 40 is fixed in position, reducing displacement and loosening caused by external forces, but also avoids the risk of display abnormalities caused by loose connections by dispersing the gravity of the display screen and external forces, greatly enhancing the installation stability.

[0042] The first connecting structure 34 refers to the specific structural form used to connect the mounting part 30 to the housing. For example, bolts, nuts, and washers in a bolt-nut structure; elastic snaps, slots, and press-to-unlock blocks in a snap-fit ​​connection structure; dovetail protrusions, dovetail grooves, and positioning pins in a dovetail groove connection structure; and pins, pin holes, and cotter pins in a pin connection structure can all serve as the first connecting structure 34. Each of these components achieves a stable connection or convenient disassembly / reassembly between the mounting part 30 and the housing through different connecting principles and methods.

[0043] In one specific embodiment, the first connecting structure 34 is a stud, and the housing has a threaded hole in which the stud is screwed. Specifically, a stud is fixedly installed at the end of the mounting part 30 body 33 away from the mounting opening 311. The outer diameter of the stud matches the inner diameter of the threaded hole on the housing, and the thread specification of the stud is consistent with that of the threaded hole. During installation, the mounting part 30 is aligned with the housing, ensuring precise alignment of the stud and the threaded hole. By turning the stud clockwise, it is gradually screwed into the threaded hole. As the stud continues to screw in, the distance between the mounting part 30 and the housing gradually decreases until they are tightly fitted, thereby achieving a stable connection between the LED display mounting part 30 and the housing. This method is simple to operate and provides a strong connection.

[0044] In this embodiment, the main body 33 is provided with a magnetic shielding thickening structure 32 on its outer periphery. The magnetic shielding thickening structure 32 is used to make the wall thickness of the mounting part 30 thicker than that in the prior art, further shielding the side residual magnetism. Magnetic materials have a guiding and confining effect on magnetic fields. When the material thickness increases, its magnetic resistance decreases, and the magnetic field is more easily conducted inside the material rather than diverging into the external space. The magnetic shielding thickening structure 32 on the outer periphery of the mounting part 30 increases the thickness, making the mounting part 30 more able to confine the magnetic field generated by the magnet part 40. In traditional mounting structures, thin walls cannot effectively block the leakage of magnetic fields, resulting in obvious magnetic leakage. However, this application constructs a stronger magnetic shielding layer by thickening the structure, which greatly reduces the degree of magnetic field leakage into the surrounding space and cuts off the source of dust attracted by magnetic leakage from the physical structure level.

[0045] The magnetic shielding thickened structure 32 can be a structure sleeved on the outside of the main body 33, or it can be part of the mounting part 30 and integrally formed with the main body 33.

[0046] See Figure 9 As shown, to facilitate the control of the main body 33 and its installation on the housing, the first connecting structure 34 in this embodiment is a threaded connection structure, and the side of the mounting part is provided with a first control structure 331. Based on the fact that the first connecting structure 34 is a stud and the housing has a threaded hole, the first control structure 331 can adopt a simple mechanical form such as a straight handle screw or a knob, avoiding complex transmission components or electronic devices. This allows operators to more easily drive the stud into or out of the threaded hole of the housing, greatly improving the convenience, controllability, and efficiency of the installation process, effectively reducing the operating threshold and installation cost, and is suitable for installation scenarios of various LED displays, from small indoor displays to large outdoor displays.

[0047] For ease of control, based on the first connecting structure 34 being a stud and the housing having a threaded hole, the first control structure 331 is an external hexagonal structure with a regular hexagonal outer contour, compatible with standard hexagonal wrenches or socket tools. By inserting the corresponding hexagonal tool into the external hexagonal structure, the operator can easily apply torque to drive the stud into or out of the housing's threaded hole. This avoids the slippage problem of manual operation and effectively reduces the difficulty of operation by utilizing the leverage effect of standard tools. It is especially suitable for installation scenarios in confined spaces or requiring precise control of tightening torque, further improving installation efficiency. It is applicable to various LED display installation scenarios, from small indoor displays to large outdoor displays.

[0048] See Figure 8 As shown, in this embodiment, the first connecting structure 34 is a threaded connection structure, and a second control structure is provided on the inner side of the mounting groove 31. The second control structure can be an internal hexagon or an internal octagon, etc. In one embodiment, an internal octagon is formed on the inner wall of the mounting groove 31. During installation, a standard internal octagon wrench is used, and the mounting part 30 can be rotated by rotating the wrench to achieve installation. During disassembly, the internal octagon wrench is rotated in the opposite direction to complete disassembly.

[0049] As described in the above embodiments, the first and / or second control structures in this application are multi-faceted control structures. The main characteristic of a multi-faceted control structure is its prismatic shape. It can be a prismatic hole, i.e., a structure with prismatic openings inside; or it can be a prism, i.e., a columnar structure with a prismatic cross-section. Common specific forms include internal hexagonal, internal octagonal, and external hexagonal. These prismatic structures facilitate use with corresponding tools; for example, an internal hexagonal wrench can be inserted into the internal hexagonal hole, and the rotation of the wrench can control the rotation or tightening of components with internal hexagonal structures. Multi-faceted control structures provide more precise control and operation. Compared to other shapes, prismatic structures can better transmit torque, allowing for more even application of force when tightening or loosening components, reducing the risk of component damage.

[0050] See Figure 4 and Figure 5 As shown, in one embodiment, the end face of the mounting portion near the display screen in this application embodiment abuts against the ferromagnetic portion 11. Direct contact between the end face of the mounting portion and the ferromagnetic portion 11 concentrates the magnetic attraction between the magnet portion 40 and the ferromagnetic portion 11, reducing the installation gap. Physical contact prevents displacement of the display screen when subjected to vibration or external impact, ensuring the stability of the connection structure during long-term use and preventing display abnormalities due to loosening. The abutment allows the ferromagnetic portion 11 to be closer to the magnet portion 40, and, combined with the sealed design of the mounting opening 311, further prevents magnetic field leakage. Ferromagnetic materials themselves have a guiding effect on magnetic fields; the end face abutment allows the magnetic field generated by the magnet portion 40 to form a closed loop more concentrated through the ferromagnetic portion 11, reducing magnetic leakage into the surrounding space and thus reducing the risk of dust adsorption. During installation, the contact surface between the end face of the mounting part and the contact surface of the ferromagnetic part 11 can serve as a clear positioning reference. Operators do not need to use additional complex positioning tools. They can quickly complete the installation and alignment simply by observing whether the two fit tightly together, thereby improving installation efficiency and reducing the problem of unstable connection caused by positioning deviation.

[0051] See Figure 6 and Figure 7As shown, in another embodiment, the mounting portion of this application embodiment has an annular protrusion 332 on the side near the display screen. A positioning recess 333 is formed inside the annular protrusion 332, and a mounting opening 311 is formed at the bottom of the positioning recess 333. The ferromagnetic portion 11 is adapted to the positioning recess 333 and is installed within the positioning recess 333. The positioning recess 333 inside the annular protrusion 332 is shape-fitted to the ferromagnetic portion 11. During installation, the ferromagnetic portion 11 needs to be embedded within the positioning recess 333 to avoid magnetic attraction failure and increased magnetic leakage due to incorrect installation direction or offset. Especially in batch installation scenarios, this can significantly reduce installation defects caused by human error. The ferromagnetic portion 11 is installed within the positioning recess 333, and its surface is flush with or slightly lower than the end face of the annular protrusion 332, allowing the ferromagnetic portion 11 to be physically protected by the annular protrusion 332. During the handling and maintenance of the display screen, the annular protrusion 332 can buffer external impact forces, preventing the ferromagnetic part 11 from being directly deformed by force, thereby ensuring the integrity of the magnetic connection structure and extending its service life. The structure of the positioning recess 333 allows for a more precise fit between the ferromagnetic part 11 and the mounting opening 311. The mounting opening 311 is formed at the bottom of the positioning recess 333, ensuring that the ferromagnetic part 11 completely covers the mounting opening 311, reducing gaps around the magnet part 40. This not only further prevents magnetic field leakage from the side of the mounting opening 311, but also reduces the possibility of dust directly accumulating at the magnetic connection point through the shielding of the annular protrusion 332, reducing the impact of dust adsorption on display effects and equipment safety.

[0052] In this embodiment, the magnet part 40 is adapted to the second control structure. Adaptation means that the geometric contours of the components correspond to each other. For example, it is adapted to the inner octagonal structure in the above embodiment, and the magnet part 40 is provided with an inner octagonal prism that is adapted to it. During installation, the operator only needs to align the inner octagonal prism of the magnet part 40 with the inner octagon of the mounting groove 31. The inner octagonal shapes fit tightly together, which not only ensures that the magnet part 40 is resistant to the influence of vibration and other factors during use after installation and prevents loosening, but also allows for fine adjustment of the angular position of the magnet part 40 through precise rotation, significantly improving the installation accuracy.

[0053] See Figure 10 and Figure 11As shown, according to another aspect of this application, an LED display device is provided. The LED display device includes a display screen and a cabinet. The display screen is provided with a ferromagnetic part 11. The LED display device also includes multiple LED display mounting structures, which are spaced apart. The LED display mounting structures are the aforementioned LED display mounting structures. Some of the multiple LED display mounting structures may have annular protrusions, while others may not have annular protrusions. By setting multiple spaced LED display mounting structures between the display screen and the cabinet, the weight of the display screen and external forces can be distributed to different positions of the cabinet, effectively avoiding structural deformation or loosening caused by excessive force at a single point. In large displays, it can balance the screen's weight to prevent bezel bending. In outdoor scenarios, it can also reduce screen shaking caused by strong winds and other external forces, improving resistance to deformation and shock. Meanwhile, some installation structures use ring-shaped protrusions while others do not, allowing for flexible adaptation to different installation needs: structures with ring-shaped protrusions are suitable for areas requiring precise alignment, such as display splicing seams, ensuring the flatness and uniformity of gaps between multiple screens; structures without ring-shaped protrusions simplify installation steps, reduce costs, and are suitable for areas with lower positioning accuracy requirements, while also being compatible with displays of different sizes and thicknesses.

[0054] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
