Description

Technical Field

[0001] The invention relates to the field of electronic technology, in particular to a chip digital tube. Background Art

[0002] SMD digital tube is a digital display device packaged using surface mount technology (SMT), which is mainly used to convert electrical signals into intuitive digital or simple character displays.

[0003] Among the many types of SMD digital tubes, LED SMD digital tubes are the most common. LED stands for light-emitting diode. LED SMD digital tubes use LED as their light source. LED SMD digital tubes are mainly composed of multiple LEDs arranged in a specific manner. The common seven-segment type is arranged in an "8" shape. Its operation is based on the principle of LED luminescence. By controlling the voltage of different pins to make the corresponding LED segments conduct and emit light, numbers or characters are displayed in combination. The driving mode is divided into static and dynamic. Static segments are independently driven and always bright, but the ports are occupied more. Dynamic segments with the same name share ports and are displayed in turn in time-sharing. Visual persistence is used to achieve stable display, so as to achieve the function of clearly and intuitively presenting information in various electronic devices. The LED chip digital tube in the prior art has a simple structure and a reasonable layout, and can well perform the LED display function. However, since traditional LED chip digital tubes are mostly in the form of independent individuals, they lack an integrated connection design and do not fully consider the connection convenience when multiple digital tubes work together. For some application scenarios that need to display multiple digits or long strips of information, the length of the digital tube cannot be extended to meet the display requirements. In actual application scenarios, when it is necessary to build a multi-digit display or a complex array display system, many digital tubes are usually connected separately on the circuit board. This connection method is not only complicated in wiring, but also very easy to cause short circuit or open circuit failures due to problems such as line crossing and poor welding, reducing the flexibility of the use of LED chip digital tubes. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a chip digital tube, which solves the problems of traditional LED chip digital tubes, such as inconvenient connection, complex wiring and prone to failure, and inability to extend the length of the digital tube to meet specific display requirements, due to the lack of integrated connection design when constructing multi-digit digital displays or complex array display systems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a chip digital tube, comprising a PCB board, a shell is assembled on the top of the PCB board, a splicing component is arranged between a pair of the shells, a display structure is arranged on the top of the shell, a heat dissipation component and a dustproof component are arranged in sequence in the middle of the shell, an adhesive component is arranged between the top of the PCB board and the bottom of the shell, and an auxiliary component is arranged on the top of the PCB board; The splicing assembly includes a protrusion, which is fixedly connected to one end of the shell, a slot is provided at the other end of the shell, an annular groove is provided on the inner side of the shell, a snap-in groove is provided on the inner wall of the annular groove, and a snap-in ball is assembled on the inner side of the protrusion.

[0006] Preferably, the auxiliary component includes a fixing block 1, which is mounted on the top of the PCB board, the top of the fixing block 1 is fixedly connected to a fixing block 2, the middle of the fixing block 1 is equipped with a rotating shaft, the outer side of the rotating shaft is fixedly connected to a convex rod, and a groove is provided on the side of the outer shell close to the fixing block 1.

[0007] Preferably, the adhesive assembly comprises a hot-melt adhesive tape, the hot-melt adhesive tape is arranged at the bottom end of the shell, a limiting groove is provided at the top of the PCB board, and the shell is snap-fitted to the limiting groove.

[0008] Preferably, the heat dissipation assembly comprises a heat sink, the heat sink is fixedly connected to the middle part of the shell, a heat dissipation ring is arranged on the inner side of the heat sink, and a heat dissipation hole is arranged on a side of the heat dissipation ring away from the heat sink.

[0009] Preferably, the dustproof component comprises a filter plate, the filter plate is mounted on the outer side of the shell, a slider is slidably connected to the middle of the filter plate, and a plurality of brushes are evenly distributed on the inner side of the slider.

[0010] Preferably, the protrusion is slidably connected to the middle of the slot, and the engaging ball is engaged with the engaging slot.

[0011] Preferably, a spring rod is provided inside the second fixing block, one end of the spring rod away from the second fixing block is fixedly connected to the convex rod, and the convex rod is clamped together with the groove.

[0012] Preferably, a moving rod is slidably connected inside the fixing block 1, and one end of the moving rod close to the rotating shaft is in contact with the protruding rod.

[0013] Preferably, the top of the sliding block is fixedly connected to a limiting block, and the limiting block is specifically provided in pair.

[0014] Preferably, a slide groove is provided in the middle of the filter plate, and the limit block is slidably connected to the middle of the slide groove.

[0015] The present invention provides a chip digital tube having the following beneficial effects: 1. The present invention inserts a protrusion on the outer side of a shell from a slot position into another shell, and then rotates one of the shells, so that the protrusion rotates along the annular groove. When the snap-in ball reaches the snap-in groove position, it enters the middle of the snap-in groove under the action of its own elasticity and completes the snap-in connection with the snap-in groove, so that the two shells are snap-fitted together, so that the adjacent SMD digital tube shells are tightly connected and stably fixed, which greatly improves the flexibility and adaptability of the use of LED SMD digital tubes.

[0016] 2. In the present invention, the hot-melt adhesive tape melts when heated to fill the gap between the shell and the PCB board, and forms a strong adhesive layer after cooling to tightly fit the two. At the same time, the shell is inserted into the limit groove on the top of the PCB board to accurately position the shell and effectively prevent the horizontal displacement of the shell, which helps to improve the stability of the connection between the shell and the PCB board and avoid loosening due to vibration or external force during the operation of the LED chip digital tube, thereby improving the reliability and durability of the overall structure of the LED chip digital tube and reducing the probability of failures such as poor contact or unstable electrical performance due to loose connections.

[0017] 3. In the present invention, the outer wall of the shell falls close to the fixed block, and the outer wall contacts and squeezes the convex rod, and the convex rod compresses the spring rod. When the shell continues to fall to a suitable position, the spring rod releases elastic potential energy to push the convex rod to rebound, so that the convex rod is stuck in the groove of the shell. The convex rod limits the shell, so that the shell can be accurately installed in the predetermined position, avoiding the problem of poor internal circuit connection or uneven force on components due to installation deviation, and effectively improving the installation quality and efficiency of LED chip digital tubes.

[0018] 4. The present invention can quickly absorb heat by closely contacting the heat sink with the heating element. After the heat is conducted to the heat sink, it is further diffused through the heat dissipation ring. The heat dissipation ring enables the heat to be more efficiently transferred to the vicinity of the heat dissipation hole. The heat is dissipated into the surrounding environment through the heat dissipation hole, thereby preventing the problems of reduced luminous efficiency and shortened life of the light-emitting diode due to overheating, as well as performance degradation of other electronic components. The performance stability of the LED chip digital tube is maintained under long-term operation, the service life is extended, and good display effect and reliability are ensured.

[0019] 5. The present invention blocks dust particles in the air from entering the interior of the LED SMD digital tube by distributing tiny pores on the filter plate. When cleaning the filter plate, slide the slider, which moves smoothly along the slide groove in the middle of the filter plate, and uses the brush on its inner side to comprehensively clean the surface of the filter plate. The limit block slides in the slide groove to limit the moving range of the slider and ensure the accuracy of its moving direction, thereby ensuring the continuity of the dustproof effect, facilitating regular cleaning and maintenance of the filter plate, reducing the failure rate of the LED SMD digital tube caused by dust accumulation, ensuring the stable operation of the LED SMD digital tube, and reducing maintenance costs.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Please see attached Figure 1 -Attached Figure 4 The embodiment of the present invention provides a chip digital tube, including a PCB board 1, a shell 2 is assembled on the top of the PCB board 1, a splicing component 3 is arranged between a pair of shells 2, a display structure 8 is arranged on the top of the shell 2, a heat dissipation component 6 and a dustproof component 7 are arranged in sequence in the middle of the shell 2, an adhesive component 5 is arranged between the top of the PCB board 1 and the bottom of the shell 2, and an auxiliary component 4 is arranged on the top of the PCB board 1; The splicing assembly 3 includes a protrusion 31, which is fixedly connected to one end of the shell 2. A slot 32 is provided at the other end of the shell 2. An annular groove 34 is provided on the inner side of the shell 2. A snap-in groove 35 is provided on the inner wall of the annular groove 34. A snap-in ball 33 is assembled on the inner side of the protrusion 31. The protrusion 31 is slidably connected to the middle of the slot 32, and the snap-in ball 33 and the snap-in groove 35 are snap-fitted.

[0024] By aligning the protrusion 31 at one end of one shell 2 with the slot 32 at the other end of the other shell 2, the protrusion 31 has a precisely designed size and shape, a smooth surface and a certain degree of guidance, and can be inserted into the slot 32 very smoothly, and the two maintain a moderate tightness, which can not only ensure that the protrusion 31 will not shake or deviate during the insertion process, but also provide stable support during the subsequent rotation operation. When the protrusion 31 is fully inserted into the slot 32, the protrusion 31 is just located in the annular groove 34 on the inner side of the shell 2. Then, when one of the shells 2 is rotated, the protrusion 31 will rotate smoothly along the annular groove 34. During the rotation process, the protrusion 31 The snap-in ball 33 assembled on the inner side also moves synchronously. The snap-in ball 33 is usually made of rubber or plastic material with excellent elasticity. Its surface is specially treated to have certain friction and wear resistance. When the snap-in ball 33 reaches the snap-in groove 35 position on the inner wall of the annular groove 34 as the protrusion 31 rotates, due to the snap-in ball 33's own elasticity and its high matching with the shape of the snap-in groove 35, the snap-in ball 33 will be moderately deformed when slightly squeezed by the edge of the snap-in groove 35, so that it can smoothly enter the middle of the snap-in groove 35. Once the snap-in ball 33 completely enters the snap-in groove 35, it will rely on its own elasticity to restore to its original state and be tightly snap-in with the snap-in groove 35. This method does not require the use of complex tools or additional connecting components, and can achieve close connection and stable fixation of adjacent LED chip digital tube housings 2 through simple manual operations. When constructing a multi-digit display or a complex array display system, the operator can quickly and flexibly splice multiple LED chip digital tubes according to actual needs, effectively solving the problem that traditional LED chip digital tubes are inconvenient to connect and cannot meet the needs of long strip information display. It helps to improve the flexibility and adaptability of the use of LED chip digital tubes and improve the reliability and stability of the entire display system.

[0025] Please see attached Figure 1 , Attachment Figure 7The auxiliary component 4 includes a fixing block 41, which is assembled on the top of the PCB board 1. The top of the fixing block 41 is fixedly connected to a fixing block 42. A rotating shaft 44 is assembled in the middle of the fixing block 41. A convex rod 43 is fixedly connected to the outer side of the rotating shaft 44. A groove 47 is provided on the side of the housing 2 close to the fixing block 41. A spring rod 46 is arranged inside the fixing block 42. One end of the spring rod 46 away from the fixing block 42 is fixedly connected to the convex rod 43. The convex rod 43 is clamped together with the groove 47. A moving rod 45 is slidably connected to the inside of the fixing block 41. One end of the moving rod 45 close to the rotating shaft 44 is abutted against the convex rod 43.

[0026] The outer shell 2 slowly falls and approaches the fixing block 1 41, so that the outer wall of the outer shell 2 first contacts the convex rod 43. In the initial state, the convex rod 43 is at a certain tilt angle due to the elastic force of the spring rod 46, and forms a certain angle with the falling direction of the outer shell 2. When the outer wall of the outer shell 2 squeezes the convex rod 43, the convex rod 43 starts to rotate around the rotating shaft 44. During the rotation, the convex rod 43 gradually compresses the spring rod 46 inside the fixing block 2 42, so that the spring rod 46 stores a large amount of elastic potential energy. As the outer shell 2 continues to fall, when it reaches a suitable position, the spring rod 46 releases the stored elastic potential energy, pushing The movable protruding rod 43 rebounds quickly, and the protruding rod 43 after rebounding is accurately stuck in the groove 47 of the shell 2, so that the shell 2 is fixed on the PCB board 1. In the whole process, the moving rod 45 slidably connected inside the fixing block 41 plays an auxiliary role. The end of the moving rod 45 close to the rotating shaft 44 abuts against the protruding rod 43. When the protruding rod 43 rotates, the moving rod 45 will slide accordingly inside the fixing block 41, and its sliding direction and distance match the rotation angle and amplitude of the protruding rod 43, providing stable support and guidance for the rotation of the protruding rod 43, ensuring that the protruding rod 43 can smoothly complete the rotation and rebound action; This method enables the housing 2 to be accurately limited and assisted in fixation during the installation process. The limiting effect of the protruding rod 43 on the housing 2 is very critical. It can enable the housing 2 to be accurately installed in the predetermined position, avoiding problems such as poor internal circuit connection or uneven force on components caused by installation deviation. The clamping connection between the protruding rod 43 and the groove 47 and the auxiliary fixation of the spring rod 46 greatly enhance the stability of the housing 2 on the PCB board 1, which helps to improve the anti-interference ability of the LED chip digital tube in complex usage environments.

[0027] Please see attached Figure 5 , Attachment Figure 6 The adhesive component 5 includes a hot melt tape 51, which is arranged at the bottom end of the shell 2. A limiting groove 52 is opened on the top of the PCB board 1, and the shell 2 and the limiting groove 52 are snap-fitted together.

[0028] By placing the housing 2 at a corresponding position above the PCB board 1, the hot melt tape 51 at the bottom of the housing 2 is lightly in contact with the surface of the PCB board 1. As the temperature rises and reaches the melting point of the hot melt tape 51, the hot melt tape 51 begins to melt gradually, and its viscous material becomes fluid, which can evenly fill the small gap between the housing 2 and the PCB board 1, including the gap caused by the uneven surface caused by the manufacturing process. In the process of the hot melt tape 51 filling the gap, the housing 2 is simultaneously inserted into the limiting groove 52 at the top of the PCB board 1. The size of the limiting groove 52 matches the corresponding part of the housing 2, so that the housing 2 can be effectively positioned without displacement in the horizontal direction. After the hot melt tape 51 cools, it forms a strong adhesive layer, which tightly fits the housing 2 and the PCB board 1 together to form a stable overall structure. This method gives full play to the adhesive properties of the hot melt tape 51 and the positioning function of the limit groove 52. The strong adhesion provided by the hot melt tape 51 can withstand a certain amount of external force pulling and vibration, and effectively prevent the outer shell 2 from loosening due to external vibration or unexpected external force impact during the operation of the LED chip digital tube. The limit groove 52 fundamentally solves the horizontal displacement problem of the outer shell 2 and ensures the stability of the relative position between the outer shell 2 and the PCB board 1. The two work together to greatly improve the stability of the connection between the outer shell 2 and the PCB board 1, ensure the stable working environment of the internal electronic components, and reduce the probability of failures such as poor contact or unstable electrical performance caused by loose connections. Thereby improving the reliability and durability of the overall structure of the chip digital tube.

[0029] Please see attached Figure 5 , Attachment Figure 8 The heat dissipation assembly 6 includes a heat sink 61 , which is fixedly connected to the middle of the housing 2 , a heat dissipation ring 62 is arranged on the inner side of the heat sink 61 , and a heat dissipation hole 63 is arranged on the side of the heat dissipation ring 62 away from the heat sink 61 .

[0030] The heat sink 61 is made of a metal material with a high thermal conductivity, such as an aluminum alloy or a copper alloy. It fits tightly with the heating element inside the digital tube, and the fitting surface is finely polished to ensure maximum heat conduction efficiency. When the heating element generates heat, the heat can be quickly conducted to the heat sink 61. The heat sink 61 has a unique sheet structure, and its design shape and layout are optimized to effectively disperse the heat. The heat conducted to the heat sink 61 is then transferred to the heat sink ring 62. The heat sink ring 62 surrounds the inner side of the heat sink 61 and is made of a material with good thermal conductivity and a certain specific heat capacity, such as ceramics or special metal composite materials. The annular structure of the heat sink ring 62 further increases the contact area between heat and air. After the heat is evenly distributed in the heat sink ring 62, it is gradually transferred to the vicinity of the heat dissipation holes 63. The heat dissipation holes 63 are evenly distributed on the side of the heat sink ring 62 away from the heat sink 61. The aperture size and number of the heat dissipation holes are accurately calculated and designed to ensure that the heat can be smoothly dissipated to the surrounding environment. When there is air flow in the surrounding environment, such as under the condition of natural ventilation or fan-assisted ventilation, the heat will quickly diffuse out from the heat dissipation holes 63 along with the flow of air, forming an effective heat dissipation channel; This method can control the internal temperature of the LED SMD digital tube within a reasonable range, maintain performance stability under long-term operation, extend service life, reduce the cost of repair and replacement of faults caused by overheating, improve the overall stability and service life of the LED SMD digital tube, and provide users with a more lasting and high-quality use experience.

[0031] Please see attached Figure 5 , Attachment Fig. 9 The dustproof component 7 includes a filter plate 71, which is assembled on the outside of the shell 2. A slider 72 is slidably connected to the middle of the filter plate 71. A plurality of brushes 73 are evenly distributed on the inner side of the slider 72. A limiting block 74 is fixedly connected to the top of the slider 72. The limiting block 74 is specifically provided with a pair of limiting blocks. A slide groove 75 is opened in the middle of the filter plate 71. The limiting block 74 is slidably connected to the middle of the slide groove 75.

[0032] The tiny pores of the filter plate 71 can effectively prevent dust particles in the air from entering the interior of the LED SMD digital tube. When the outside air flows through the filter plate 71, the dust particles are intercepted on the outer surface of the filter plate 71 and cannot enter the interior of the LED SMD digital tube, thereby protecting the internal electronic components from dust pollution. The operator manually operates the slider 72 to make the slider 72 move smoothly along the slide groove 75 in the middle of the filter plate 71. The inner wall of the slide groove 75 is smooth, providing a stable sliding track for the slider 72. The multiple brushes 73 evenly distributed on the inner side of the slider 72 and the surface of the filter plate 71 are The brush 73 is in close contact with the filter plate 71 through the movement of the slider 72, so that the dust particles attached to the outer surface of the filter plate 71 are swept away. A pair of limit blocks 74 are fixedly connected to the top of the slider 72. The shape and size of the limit blocks 74 are adapted to the two ends of the slide groove 75. When the slider 72 slides to the two ends of the slide groove 75, the limit blocks 74 will contact the ends of the slide groove 75, thereby limiting the movement range of the slider 72 to ensure that it will not slide out of the slide groove 75. At the same time, the accuracy of the moving direction of the slider 72 is also ensured, so that it always moves in a straight line along the slide groove 75. This method can easily complete the cleaning operation without the help of complex tools or professional skills. It not only ensures the stable operation of the LED SMD digital tube, reduces the maintenance cost and downtime caused by dust problems, but also extends the product life cycle, improves the product reliability and maintainability, and enables the LED SMD digital tube to work stably even in a dusty environment, providing strong support for the normal operation of electronic equipment in various complex environments.

[0033] Working principle: When splicing and expanding the chip digital tube, the protrusion 31 on the outside of one shell 2 is inserted from the slot 32 into the inside of another shell 2, and then one of the shells 2 is rotated, and the protrusion 31 will rotate along the annular groove 34. When the snap-in ball 33 reaches the snap-in groove 35, it can enter the middle of the snap-in groove 35 under the action of its own elasticity, and complete the snap-in connection with the snap-in groove 35, thereby realizing the assembly of the two shells 2, so that the adjacent chip digital tube shells 2 are tightly connected and stably fixed, so that the length of the digital tube can be flexibly extended according to the display requirements to meet the display requirements of multi-digit numbers or long strip information.

[0034] When the PCB board 1 is adhered to the shell 2, the hot-melt adhesive tape 51 can tightly adhere the shell 2 to the PCB board 1, and at the same time, the shell 2 is inserted into the limiting groove 52 at the top of the PCB board 1, which further enhances the stability of the connection, making the fixation between the shell 2 and the PCB board 1 reliable, avoiding undesirable phenomena such as loosening or displacement during use. At the same time, when the shell 2 falls along the convex rod 43, the outer wall of the shell 2 squeezes the convex rod 43, and the convex rod 43 rotates under the support of the rotating shaft 44 and squeezes the spring rod 46, so that the shell 2 falls smoothly to the top of the PCB board 1. At the same time, the convex rod 43 is clamped together with the groove 47 to complete the fixation of the shell 2 on the PCB board 1, which is convenient for limiting and auxiliary fixation of the adhesion of the PCB board 1 and the shell 2.

[0035] When the LED chip digital tube dissipates heat, the heat sink 61 can quickly conduct the heat generated when the digital tube is working, and the heat dissipation ring 62 further expands the heat dissipation area. The heat is dissipated to the surrounding environment through the heat dissipation holes 63. In this way, the temperature inside the digital tube is effectively reduced.

[0036] When the LED SMD digital tube is dust-proof and dust-removed, a filter plate 71 is provided to prevent external dust from entering the interior of the digital tube. When the filter plate 71 needs to be cleaned, the slider 72 is slid, and the brush 73 on the inner side of the slider 72 can clean the surface of the filter plate 71. The limit block 74 slides in the slide groove 75 to ensure the smoothness and direction of the sliding of the slider 72, thereby ensuring the reliability and stability of the operation of the LED SMD digital tube.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
