Description

Technical Field

[0001] This utility model relates to the field of digital tube technology, and in particular to an LED digital tube. Background Technology

[0002] After the existing LED digital tube is packaged, several metal pins extend straight out from the body and are exposed. During subsequent transportation and storage, the pins are prone to collisions and squeezing with turnover boxes, pallets, or adjacent devices, resulting in bending, scratches, or even breakage, which damages the LED digital tube. At the same time, humid air and corrosive atmospheres containing sulfur and chlorine can easily form an oxide layer or corrosion pits on the pin surface, further damaging the LED digital tube. Utility Model Content

[0003] The main purpose of this utility model is to propose an LED digital tube that aims to solve the technical problem that LED digital tubes are easily damaged during transportation and storage.

[0004] To achieve the above objectives, the present invention proposes an LED digital tube, wherein the LED digital tube comprises:

[0005] The digital tube body has a light-emitting side and a mounting side on opposite sides. The mounting side protrudes in a direction away from the light-emitting side to form a mounting platform. The mounting side also has a first sealing surface surrounding the mounting platform. The first sealing surface is provided with a first magnetic suction element. A plurality of spaced pins are mounted on the side of the mounting platform away from the light-emitting side. Each pin is provided with a reinforcing structure at one end of the light-emitting side.

[0006] A sealing and protective structure includes a protective cover and multiple hollow conical cylinders. A first protective cavity is formed within the protective cover, and an opening communicating with the first protective cavity is also formed within the protective cover. A second sealing surface is formed on the side of the protective cover near the opening, surrounding the opening. A second magnetic element is provided on the second sealing surface. The number of hollow conical cylinders corresponds to the number of pins, and they are arranged one-to-one. Each conical cylinder is mounted on the side of the protective cover away from the opening. Each hollow conical cylinder gradually tapers in size away from the protective cover, and a second protective cavity is formed within each conical cylinder. The second protective cavity communicates with the first protective cavity. A mounting platform matches the shape of the opening and extends through the opening into the first protective cavity. Each pin extends into its corresponding second protective cavity. The first magnetic element and the second magnetic element magnetically engage to abut and seal the first sealing surface and the second sealing surface.

[0007] In one embodiment, the first sealing surface is provided with a first sealing element, which surrounds the mounting platform; the second sealing surface is provided with a second sealing element, which surrounds the opening; and the first sealing element and the second sealing element are in a sealing fit.

[0008] In one embodiment, the first sealing surface is recessed towards the light-emitting side to form a first receiving groove, the first magnetic suction member is disposed in the first receiving groove, and the first sealing member covers the opening of the first receiving groove. The second sealing surface is recessed towards the hollow conical cylinder to form a second receiving groove, the second magnetic suction member is disposed in the second receiving groove, and the second sealing member covers the opening of the second receiving groove.

[0009] In one embodiment, the first receiving slot and the first magnetic member are both arranged around the mounting platform, and the second receiving slot and the second magnetic member are both arranged around the opening.

[0010] In one embodiment, a drying sheet is provided on the bottom wall of the second protective cavity, which is directly opposite the opening.

[0011] In one embodiment, the reinforcing structure includes a reinforcing ring, which is sleeved and connected to the outer periphery of the pin, and the reinforcing ring is mounted on the mounting platform.

[0012] In one embodiment, the cross-sectional area of ​​the reinforcing ring gradually decreases from the mounting platform along the pin in a direction away from the mounting platform.

[0013] In one embodiment, the reinforcing ring is a ceramic reinforcing ring.

[0014] In one embodiment, the outer periphery of the pin is plated with an anti-corrosion coating.

[0015] In one embodiment, the anti-corrosion coating is a palladium-nickel alloy coating.

[0016] The technical solution of this utility model employs a mounting platform protruding away from the light-emitting side, a first sealing surface surrounding the mounting platform, and a first magnetic suction component. This allows the protective cover of the sealed protective structure to magnetically connect with the digital tube body via a second magnetic suction component. When the mounting platform extends into the first protective cavity through the opening of the protective cover, each pin is inserted into the corresponding hollow conical cylinder of the second protective cavity. The first and second sealing surfaces abut and seal under the action of magnetic attraction, thus completely enclosing the pins within a continuous cavity formed by the first protective cavity and multiple second protective cavities. This prevents the pins from being bumped, squeezed, bent, or broken by external objects during transportation and storage, while also isolating them from humid air and corrosive gases, preventing oxidation or corrosion. Each hollow conical cylinder gradually narrows away from the protective cover, forming a continuous conical guide channel. Even if there is a positional deviation when the pin is inserted, it can automatically slide into the center along the conical surface, avoiding collisions or scratches. Furthermore, the gradually tapering conical profile of each hollow conical cylinder, moving away from the protective cover, creates a continuous reinforcing rib structure on the circumferential wall, further enhancing the bending and torsional stiffness of the hollow conical cylinder. When external impacts or stacking pressure are transmitted to the conical cylinder through the protective cover, the force lines are evenly distributed along the conical surface, preventing stress concentration that could lead to cracking or collapse, thus providing better protection for the pins. A reinforcing structure is also provided at the root of the pins, further enhancing the reliability of the connection between the pins and the mounting platform and further reducing the possibility of pin damage. The magnetic attraction of the first and second magnetic components allows for quick and precise alignment of the protective cover and the mounting platform without the need for additional positioning tools or complex assembly steps. When the first and second magnetic components engage, the first and second sealing surfaces fit tightly together, forming a reliable seal that effectively isolates the pins from external humid air and corrosive gases, protecting them from oxidation and corrosion. It also provides additional fixing force between the protective cover and the mounting platform, enhancing the overall structural stability. Even when subjected to bumps or vibrations during transportation, the protective cover is not easily loosened or detached, ensuring that the pins are always protected. The protective cover can be quickly and easily installed onto the digital tube body via magnetic attachment. Attached Figure Description

[0028] This utility model proposes an LED digital tube.

[0029] Please see Figures 1 to 4 In one embodiment of this utility model, the LED digital tube includes a digital tube body 10 and a sealing protection structure 20. The digital tube body 10 has a light-emitting side 11 and a mounting side 12 on opposite sides. The mounting side 12 protrudes away from the light-emitting side 11 to form a mounting platform 13. The mounting side 12 also forms a first sealing surface 14 surrounding the mounting platform 13. The first sealing surface 14 is provided with a first magnetic suction element 15. Multiple spaced pins 16 are mounted on the side of the mounting platform 13 away from the light-emitting side 11. Each pin 16 is mounted at one end of the light-emitting side 11 and is provided with a reinforcing structure 17. The sealing protection structure 20 includes a protective cover 21 and multiple hollow conical cylinders 22. A first protective cavity 211 is formed inside the protective cover 21. The protective cover 21 has an opening 214 communicating with the first protective cavity 211. The protective cover 21 is close to the opening... A second sealing surface 212 is formed on one side of the opening 214. The second sealing surface 212 surrounds the opening 214 and is provided with a second magnetic suction member 213. A plurality of hollow conical cylinders 22 are provided in the same number as the pins 16 and are arranged in a one-to-one correspondence. The plurality of conical cylinders are all installed on the side of the protective cover 21 away from the opening 214. Each hollow conical cylinder 22 gradually shrinks in the direction away from the protective cover 21. A second protective cavity 221 is formed inside each conical cylinder. The second protective cavity 221 communicates with the first protective cavity 211. The mounting platform 13 is shaped to match the opening 214. The mounting platform 13 extends through the opening 214 and into the first protective cavity 211. Each pin 16 extends into its corresponding second protective cavity 221. The first magnetic suction member 15 and the second magnetic suction member 213 are magnetically attracted to each other so that the first sealing surface 14 and the second sealing surface 212 abut and seal.

[0030] The technical solution of this utility model adopts a mounting platform 13 protruding from the mounting side 12 away from the light-emitting side 11, a first sealing surface 14 surrounding the mounting platform 13, and a first magnetic suction member 15, so that the protective cover 21 of the sealing protection structure 20 can be magnetically connected to the digital tube body 10 by means of the second magnetic suction member 213; when the mounting platform 13 extends into the first protective cavity 211 through the opening 214 of the protective cover 21, each pin 16 is inserted into the second protective cavity 221 of the hollow conical cylinder 22 corresponding to it. The first sealing surface 14 and the second sealing surface 212 abut and seal under the action of magnetic attraction, thereby completely enclosing the pin 16 in the continuous cavity formed by the first protective cavity 211 and multiple second protective cavities 221, avoiding the pin 16 from being bumped, squeezed and bent or broken by external objects during transportation and storage, while isolating humid air and corrosive gases, preventing the pin 16 from oxidizing or corroding. Each hollow conical cylinder 22 gradually tapers away from the protective cover 21, forming a continuous conical guide channel within the cylinder cavity. Even with positional deviations, the pin 16 can automatically slide into the center along the conical surface during insertion, preventing collisions or scratches. Furthermore, the tapered profile of each hollow conical cylinder 22, gradually tapering away from the protective cover 21, creates a continuous reinforcing rib structure in the circumferential direction of the cylinder wall, further improving the bending and torsional stiffness of the hollow conical cylinder 22. When external impacts or stacking pressure are transmitted to the conical cylinder via the protective cover 21, the force lines are evenly distributed along the conical surface, preventing stress concentration that could lead to cracking or collapse, thus providing better protection for the pin 16. A reinforcing structure 17 is also provided at the root of the pin 16, further enhancing the reliability of the connection between the pin 16 and the mounting platform 13 and further reducing the possibility of damage to the pin 16. Through the magnetic attraction of the first magnetic member 15 and the second magnetic member 213, precise alignment of the protective cover 21 and the mounting platform 13 can be achieved quickly without additional positioning tools or complex assembly steps. When the first magnetic clasp 15 and the second magnetic clasp 213 are attracted together, the first sealing surface 14 and the second sealing surface 212 fit tightly together, forming a reliable seal that effectively isolates the pins from external humid air and corrosive gases, protecting them from oxidation and corrosion. It also provides additional fixing force between the protective cover 21 and the mounting platform 13, enhancing the overall structural stability. Even if bumps or vibrations occur during transportation, the protective cover 21 is not easily loosened or detached, ensuring that the pins 16 are always protected. The magnetic attraction allows the protective cover 21 to be quickly installed on the digital tube body 10, making installation simple and convenient.

[0031] In one embodiment of the present invention, a first sealing surface 14 is provided with a first sealing element 141, which surrounds the mounting platform 13; a second sealing surface 212 is provided with a second sealing element 2121, which surrounds the opening 214; and the first sealing element 141 and the second sealing element 2121 are sealed together.

[0032] Specifically, such as Figure 2 and Figure 4 As shown, a first sealing element 141 is provided on the first sealing surface 14, and a second sealing element 2121 is provided on the second sealing surface 212. Both the first sealing element 141 and the second sealing element 2121 are rubber seals. When the first magnetic attractor 15 and the second magnetic attractor 213 are magnetically engaged, the first sealing element 141 and the second sealing element 2121 abut against each other and form a sealing fit. Through the sealing fit of the first sealing element 141 and the second sealing element 2121, a more reliable seal can be formed, more effectively isolating external humid air and corrosive gases, and further protecting the pin 16 from oxidation and corrosion.

[0033] In one embodiment of the present invention, the first sealing surface 14 is recessed toward the light-emitting side 11 to form a first receiving groove 142, the first magnetic suction member 15 is disposed in the first receiving groove 142, the first sealing member 141 is covered at the opening of the first receiving groove 142, the second sealing surface 212 is recessed toward the hollow conical cylinder 22 to form a second receiving groove 2122, the second magnetic suction member 213 is disposed in the second receiving groove 2122, and the second sealing member 2121 is covered at the opening of the second receiving groove 2122.

[0034] Furthermore, such as Figure 2 and Figure 4 As shown, a continuous first receiving groove 142 is machined around the outer edge of the first sealing surface 14 of the digital tube body 10. The groove depth is slightly greater than the thickness of the first magnetic member 15. The first magnetic member 15 (such as a soft magnetic alloy ring) is embedded in the bottom of the groove and is flush with or slightly lower than the bottom of the groove. Subsequently, the first sealing member 141 is placed over the opening of the first receiving groove 142, and the outer edge of the first sealing member 141 is flush with the first sealing surface 14. Correspondingly, a continuous second receiving groove 2122 is also machined around the second sealing surface 212 of the protective cover 21. The second magnetic member 213 (with polarity opposite to the first magnetic member 15) is embedded in the bottom of the groove. The second sealing member 2121 covers the opening of the second receiving groove 2122. When the protective cover 21 and the mounting platform 13 are magnetically closed, the first sealing member 141 and the second sealing member 2121 are pressed against each other at the opening of the groove, producing uniform and continuous elastic deformation, while completely sealing their respective magnetic members in the receiving groove, preventing the magnetic members from being exposed. By embedding the first magnetic attractor 15 in the first receiving groove 142 and the second magnetic attractor 213 in the second receiving groove 2122, it is possible to effectively block corrosive media such as water vapor, sulfur, and chlorine, prevent the magnetic attractor from oxidizing or rusting, and maintain stable magnetic properties for a long time.

[0035] In one embodiment of the present invention, the first receiving groove 142 and the first magnetic member 15 are both arranged around the mounting platform 13, and the second receiving groove 2122 and the second magnetic member 213 are both arranged around the opening 214.

[0036] Furthermore, the first receiving groove 142 and the first magnetic attractor 15 are continuously arranged around the mounting platform 13, and the second receiving groove 2122 and the second magnetic attractor 213 are continuously arranged around the opening 214, so that the magnetic attractors form a closed annular magnetic circuit in their respective grooves. During assembly, the two annular magnetic attractors are coaxially aligned and magnetically attracted together, and the magnetic attraction force is evenly distributed along the entire circumference, which can more firmly attract the protective cover 21 to the mounting side 12, and also make the first sealing member 141 and the second sealing member 2121 uniformly compressed in the circumferential direction, making the seal more reliable.

[0037] In one embodiment of the present invention, a drying sheet 23 is provided on the bottom wall of the second protective cavity 221 opposite to the opening 214.

[0038] Specifically, such as Figure 2 As shown, a drying plate 23 is fixed on the bottom cavity wall opposite to the opening 214 inside the second protective cavity 221. The drying plate 23 is located between the end of the pin 16 and the cavity wall, and does not contact the pin 16. When the protective cover 21 and the digital tube body 10 are magnetically closed, the drying plate 23 immediately absorbs the residual moisture in the cavity, so that the second protective cavity 221 continues to maintain a low humidity environment, further preventing condensation, oxidation or corrosion on the surface of the pin 16, and significantly extending the reliability during storage and transportation.

[0039] In one embodiment of the present invention, the reinforcing structure 17 includes a reinforcing ring 171, which is sleeved and connected to the outer periphery of the pin 16, and the reinforcing ring 171 is mounted on the mounting platform 13.

[0040] Specifically, on the side of the mounting platform 13 facing the pin 16, a reinforcing ring 171 is formed around the outer periphery of the root of each pin 16. The reinforcing ring 171 can disperse the bending moment of the pin 16 under external force to the mounting platform 13, significantly reducing stress concentration at the root and preventing bending or breakage, while maintaining the perpendicularity of the pin 16 to the mounting platform 13.

[0041] In one embodiment of the present invention, the cross-sectional area of ​​the reinforcing ring 171 gradually decreases from the mounting platform 13 along the pin 16 in a direction away from the mounting platform 13.

[0042] Specifically, such as Figure 4 As shown, the reinforcing ring 171 is integrally formed with the mounting platform 13. Its cross-section transitions from the mounting platform 13 to a continuously tapered or arc-shaped section along the axial direction of the pin 16 away from the mounting platform 13. The cross-section is largest near the root of the mounting platform 13, forming a high-rigidity support point, and gradually thins away from the root, thus dispersing stress concentration. This structure evenly transfers external impact loads from the root of the pin 16 to the mounting platform 13 under stress, significantly reducing the root bending moment and preventing breakage. At the same time, the tapered profile reduces material usage, making the overall structure lighter and dissipating heat faster, without increasing the package height, thus balancing strength and compactness.

[0043] In one embodiment of this utility model, the reinforcing ring 171 is a ceramic reinforcing ring 171. The reinforcing ring 171 is made directly from ceramic powder by injection molding and high-temperature sintering. Its inner hole is interference-fitted with the outer periphery of the pin 16 and fixed in place. Its outer edge is injection molded and fitted into the mounting platform 13. Ceramic is insulating, hard, and heat resistant. It not only forms a rigid support at the root of the pin 16 to block external bending moment, but also avoids metal fatigue and electrochemical corrosion, significantly improving the bending strength and long-term reliability of the pin 16.

[0044] In one embodiment of this utility model, the outer periphery of the pin 16 is electroplated with an anti-corrosion coating. After the anti-corrosion coating is electroplated on the outer periphery of the pin 16, a continuous and dense protective layer is formed on the surface, which can directly isolate moisture and corrosive atmosphere, significantly delay the oxidation and corrosion of the pin 16, and maintain the conductivity and mechanical strength for a long time.

[0045] In one embodiment of this utility model, the anti-corrosion coating is a palladium-nickel alloy coating. The palladium-nickel alloy coating has excellent chemical inertness and density, which can isolate humid air and sulfur- or chlorine-containing corrosive atmospheres for a long time, significantly delaying the oxidation or corrosion of pin 16; at the same time, it maintains good conductivity and solderability, ensuring that the electrical performance of the LED digital tube is stable and reliable during transportation, storage and subsequent welding.

[0046] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the protection scope of the present utility model.
