Description

Technical Field

[0001] This application relates to the technical field of digital tubes, and particularly to a split digital tube display structure. Background Art

[0002] A digital tube, also known as a glow tube, is an electronic device that can display numbers and other information. LED digital tube display diaphragms are widely used. The traditional one is an integrated package design, that is, an LED light source, a hollow light guide plate, a display diaphragm, and a cover plate are encapsulated into an overall digital tube display diaphragm, and fixed and welded to a circuit board through pins as the digital tube display diaphragm.

[0003] Since the single tubes of the LED tubes forming a "day" shape are prone to damage, as long as there is an individual display tube damaged, the entire display diaphragm or even the product has to be scrapped. The problem with the existing design is that it is difficult to directly repair when a single tube is damaged. Utility Model Content

[0004] In order to improve the convenience of repair, this application provides a digital tube display structure that is easy to disassemble.

[0005] This application provides a split digital tube display structure, adopting the following technical solutions:

[0006] A split digital tube display structure includes a display diaphragm, a housing, a hollow light guide plate, a circuit board, and a cover plate that are connected in sequence. The display diaphragm is attached to the outer side of the housing. The hollow light guide plate and the circuit board are both located inside the housing. The cover plate is snap-fitted and encapsulated with the housing. There is a wire harness access port for the wire harness of the circuit board left on one side of the housing. The hollow light guide plate is integrally injection-molded with the inner side of the housing. A housing buckle extends from the side of the housing, and a cover plate slot is opened on the side of the cover plate. The housing buckle and the cover plate slot are correspondingly snap-fitted.

[0007] By adopting the above technical solutions, the display diaphragm is attached to the outer side of the housing. Since the display diaphragm is made of PET material, it effectively improves the color display. During use, the wire harness access port for the circuit board when the circuit board is placed in the housing is convenient for arrangement. Then, the light emitted by the circuit board is guided by the hollow light guide plate. Since the hollow light guide plate is integrally injection-molded with the inner side of the housing, its impact resistance, moisture resistance, and dust resistance are improved compared with the traditional form. If there is a fault in the internal circuit board during use, it can be quickly disassembled through the housing buckle extending from the side of the housing and the cover plate slot opened on the side of the cover plate, and the internal circuit board can be repaired, improving the repair efficiency.

[0008] Optionally, a nano-coating is coated on the side of the hollow light guide plate facing the display diaphragm.

[0009] By adopting the above technical solution, the nano-coating is a SiO2 nano-coating with moisture-proof and moisture-absorbing functions, preventing damage to the internal circuit board caused by external humidity.

[0010] Optionally, the side of the perforated light guide plate facing the display film is provided with injection-molded support columns.

[0011] By adopting the above technical solution, the injection-molded support column 302 is used to ensure that the shell and the hollow light guide plate are stably injected as a whole.

[0012] Optionally, the inner side of the cover plate is provided with anti-bending posts for abutting the circuit board.

[0013] By adopting the above technical solution, when the cover plate and the shell are disassembled, the anti-bend post plays a role in preventing the cover plate from being deformed and damaged by external forces.

[0014] Optionally, the circuit board is also provided with an infrared receiver tube, and the side of the housing facing the display film has a through hole for the infrared receiver tube to pass through.

[0015] By adopting the above technical solution, through holes are opened for the infrared receiver tubes arranged on the circuit board, making the infrared receiver tubes more sensitive to signal reception, with a wider reception area, and improving work efficiency.

[0016] Optionally, a transparent PC board may be provided between the display film and the housing.

[0017] By adopting the above technical solution, the fine texture of the transparent PC board makes the light more uniform.

[0018] Optionally, a protective film is attached to the outside of the display film.

[0019] By adopting the above technical solution, the protective film protects the display film from scratches. In operation, the protective film makes it difficult for external dust to enter the circuit board, thus reducing dust in the circuit board and ensuring an increased service life of the circuit board.

[0020] Optionally, the number of housing clips and cover plate slots is one.

[0021] By adopting the above technical solution, the four housing clips are engaged with the cover plate slots, allowing for quick disassembly and improved work efficiency when a malfunction occurs and repair is needed.

[0022] Optionally, the number of injection-molded support columns is 2, and the number of anti-bending columns is 4.

[0023] By adopting the above technical solution, the two injection-molded support columns provide stable support for the hollow light guide plate and the shell during injection molding, and the four anti-bending columns disperse external forces, making the cover plate more resistant to bending and squeezing, and less prone to deformation and damage due to external forces.

[0024] In summary, this application includes at least one of the following beneficial effects:

[0025] 1. The hollow light guide plate and the housing are injection molded into one piece, updating the traditional design. It eliminates the need for the cumbersome and costly process of fixing the LED light source, hollow light guide plate, and housing together with pins. By injection molding the hollow light guide plate and housing together, the production cycle is shortened, production efficiency is improved, production energy consumption is significantly reduced, less material is used, and the product structure is simplified. At the same time, the hollow light guide plate and housing are made of OPP material, which can adapt to various harsh environments and work stably. This simplifies the design and improves practicality.

[0026] 2. The independent split-structure housing buckle and cover plate slots correspond to each other for quick disassembly and repair. It can be directly attached to the circuit board to become a complete digital tube display film, reducing unnecessary cumbersome operations, simplifying the production process, reducing product costs during production, and making product recycling more convenient. The disassembled parts can be directly used to replace and repair other products. Attached Figure Description

[0041] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0042] This application discloses a split-type digital tube display structure, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a display film 1, a housing 2, a perforated light guide plate 3, a circuit board 4, and a cover plate 5 connected in sequence. The display film 1 is attached to the outer side of the housing 2. The perforated light guide plate 3 is integrally injection molded with the inner side of the housing 2. A cable tray 201 is provided on one side of the housing 2 for the wiring harness of the circuit board 4 to enter. A through hole 202 is provided on the side of the housing 2 facing the display film 1 for the infrared receiver tube 401 to pass through. In use, the infrared receiver tube 401 of the circuit board 4 passes through the through hole 202 on the side of the housing 2 facing the display film 1, and the wiring harness of the circuit board 4 extends out from the cable tray 201. The perforated light guide plate 3 and the circuit board 4 are both located inside the housing 2. The circuit board 4 emits light and guides the light through the perforated light guide plate 3 on one side.

[0043] Reference Figure 4 and Figure 5 When the perforated light guide plate 3 guides light, an injection-molded support column 302 is provided on the side of the perforated light guide plate 3 facing the display film 1. The injection-molded support column 302 is integrally injection-molded on the inner side of the perforated light guide plate 3 and the housing 2 to ensure stable injection molding and to provide support, so that the perforated light guide plate 3 can work for a long time. The side of the perforated light guide plate 3 facing the display film 1 is coated with a nano-coating 301. The nano-coating 301 is an SiO2 nano-coating with moisture-proof and moisture-absorbing functions to prevent the internal circuit board 4 from being damaged by the humidity of the external environment. There is also a transparent PC board 6 between the display film 1 and the housing 2. The fine texture on the transparent PC board 6 makes the light guided by the circuit board 4 through the perforated light guide plate 3 more uniform.

[0044] Reference Figure 5 The display film 1 is attached to the outer side of the housing 2, and the display film 1 is made of PET material. It enhances the color rendering of the light that is guided through the hollow light guide plate 3 and the transparent PC plate 6.

[0045] Reference Figure 5 A protective film 7 is attached to the outside of the display film 1. The protective film 7 protects the display film 1 from scratches. In the working state, the protective film 7 makes it difficult for external dust to enter the circuit board 4, thus reducing the dust in the circuit board 4 and increasing the service life of the circuit board 4.

[0046] Reference Figure 6 The inner side of the cover plate 5 is provided with anti-bending posts 502 for supporting the circuit board 4. The anti-bending posts 502 prevent the circuit board 4 from shaking in the housing 2, and the four anti-bending posts disperse the external force, making the cover plate 5 more resistant to bending and squeezing, and less prone to deformation and damage due to external force.

[0047] Reference Figure 2 and Figure 6 If the circuit board 4 located inside the housing 2 malfunctions, a housing buckle 203 extends from the side of the housing 2, and a cover plate slot 501 is provided on the side of the cover plate 5. The housing buckle 203 and the cover plate slot 501 are separated, and the circuit board 4 is quickly disassembled and removed for repair or replacement. After replacement, the cover plate 5 and the housing 2 are fastened together by the housing buckle 203 and the cover plate slot 501, thereby achieving a fastening and sealing.

[0048] The implementation principle of the split-type digital tube display structure in this application embodiment is as follows: First, the structure is placed in the working position. When in use, the infrared receiver tube 401 of the circuit board 4 passes through the through hole 202 on the side of the housing 2 facing the display film 1 to receive signals. The wire harness of the circuit board 4 extends out from the wire harness opening 201 for easy management. The circuit board 4 emits light, which is guided by the hollow light guide plate 3 on one side. When the hollow light guide plate 3 guides the light, the light guided by the hollow light guide plate 3 passes through the fine texture on the transparent PC board 6, making the light more uniform. The outer display film 1 is made of PET material to enhance color rendering. At the same time, the protective film 7 attached to the outer side of the display film 1 protects the display film 1 from scratches and prevents external dust from easily entering the circuit board 4, thus reducing the circuit board's... The dust in 4 is removed, thus ensuring the increased service life of the circuit board 4. Under outdoor working conditions, the nano-coating 301 coated on the side of the hollow light guide plate 3 facing the display film 1 is a SiO2 nano-coating with moisture-proof and moisture-absorbing functions, preventing the internal circuit board 4 from being damaged by the humidity of the external environment. If internal damage occurs, the staff can separate the housing buckle 203 extending from the side of the housing 2 and the cover plate slot 501 opened on the side of the cover plate 5, and quickly disassemble and remove the circuit board 4 for repair and replacement. After the replacement is completed, the cover plate 5 and the housing 2 are fastened together by the housing buckle 203 and the cover plate slot 501, thereby achieving a fastening and sealing, which greatly improves the repair efficiency. In this way, the repair of a split digital tube display structure is completed.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
