[0002] The 3KW FM digital audio broadcast transmitter is a high-performance broadcasting device. Its core component, the power amplifier module, is key to its powerful transmission capabilities. This transmitter employs advanced digital audio broadcasting technology, transmitting high-quality audio signals via the FM band. Its power amplifier module features high efficiency and stability, amplifying audio signals to 3000 watts, ensuring stable signal coverage over a wide range, effectively extending equipment lifespan, and guaranteeing reliability under prolonged high-power operation. It also supports multiple modulation methods, offering strong compatibility and flexible adaptation to various broadcasting needs. Widely used in urban broadcasting, traffic information transmission, and other fields, it provides listeners with clear and stable audio services, representing a significant application of modern broadcasting technology.
[0003] In existing technologies, when a 3KW FM digital audio broadcast transmitter is used in outdoor scenarios, it is necessary to frequently switch between different power amplifier modules depending on the scenario. This leads to the drawback of equipment wear and tear. Outdoor environments are complex and varied, such as mountainous areas, plains, or the edge of cities. Different scenarios have different requirements for signal coverage and power, which means that the power amplifier modules need to be constantly disassembled and replaced. This increases the risk of mechanical wear and electrical failure, affecting the performance and lifespan of the equipment. In addition, the disassembly and assembly process requires professional technicians, which increases maintenance costs and time, limits the stability and reliability of the transmitter, and affects its long-term efficient operation in complex outdoor environments. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a 3KW FM band digital audio broadcast transmitter.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a 3KW FM band digital audio broadcast transmitter, including a body, a component slot is provided on one side of the body, a power amplifier module is provided on the inner wall of the component slot, the power amplifier module is slidably connected to the inner wall of the component slot through a sliding component, a snap-fit component slot is provided on the inner wall of the component slot, a snap-fit slider slot is provided on the inner wall of the snap-fit component slot, two snap-fit shafts are provided on the inner wall of the snap-fit component slot, a snap-fit slider block is fixed at both ends of the two snap-fit shafts, the snap-fit slider block is slidably connected to the inner wall of the snap-fit slider slot, springs are fixed on both sides of the snap-fit slider block, the other end of the spring is fixed to the inner wall of the snap-fit slider slot, and a snap-fit seat is fixed on one side of the power amplifier module.
[0006] Preferably, the bottom of the machine body is provided with a bearing sliding groove, and a first support plate and a second support plate are fixed on the inner wall of the bearing sliding groove. A lead screw is rotatably connected to the top of the first support plate, and the other end of the lead screw is rotatably connected to the bottom of the second support plate. An X-shaped bearing plate is threaded onto the surface of the lead screw. The lead screw is driven to rotate by a drive assembly, and a caster wheel is fixed to the bottom of the X-shaped bearing plate. In existing technologies, 3KW FM digital audio broadcast transmitters present numerous inconveniences for outdoor work due to their large size and weight. These transmitters typically require fixed installation locations, and relocation necessitates multiple personnel or the use of lifting equipment, significantly limiting their flexibility. In complex and varied outdoor environments, such as mountainous areas, hilly terrain, or temporary event sites, the need for frequent relocation is difficult to meet, leading to low deployment and adjustment efficiency. Furthermore, the weight of the equipment increases transportation costs and installation difficulty, especially in remote areas or locations with poor transportation, where the transportation and installation process is time-consuming and labor-intensive. This difficulty in relocation not only reduces the transmitter's practicality but also increases the investment of manpower and resources, limiting its widespread application and rapid response capabilities in outdoor scenarios. To address these issues, this invention adopts a convenient relocation structure. When the unit needs to be moved, the drive assembly is activated to rotate the lead screw. This causes the X-shaped support plate to move downwards, ensuring the casters make full contact with the ground and supporting the amplifier module. At this point, pushing the component slot allows for movement. Once at the designated location, restarting the drive assembly rotates the X-shaped support plate, causing the lead screw to rise and the casters to detach from the ground, completing the movement. This significantly improves the flexibility and responsiveness of the device in outdoor scenarios. The equipment can be easily moved and redeployed in complex terrains such as mountains, hills, or temporary event sites without relying on multiple people or lifting equipment, greatly improving installation and adjustment efficiency. Simultaneously, it reduces transportation costs and installation difficulty, especially in remote areas or places with poor transportation, enabling rapid deployment and reducing manpower and material costs. Furthermore, the device's lightweight and portability enhance its practicality, allowing for wider application in various outdoor scenarios, meeting broadcasting needs in different environments, and improving overall operational efficiency and service quality.
[0007] Preferably, the drive assembly includes a first bevel gear, which is fixed to the top of the lead screw. A support block is fixed to the inner wall of the bearing sliding groove. A drive rod is rotatably connected through one side of the support block. A second bevel gear is fixed to one end of the drive rod, and a third bevel gear is fixed to the other end. The second bevel gear meshes with the surface of the first bevel gear, and a fourth bevel gear meshes with the surface of the third bevel gear. The fourth bevel gear is driven to rotate by a servo motor, which is fixed to one side of the machine body. In existing technologies, placing a servo motor inside a 3KW FM digital audio broadcast transmitter significantly interferes with the transmitter's signal quality. The servo motor generates electromagnetic noise during operation, which enters the transmitter's circuitry through electromagnetic induction or conduction, interfering with the transmission and processing of digital audio signals. This interference can lead to audio signal distortion, noise, and even affect the stability and coverage of the FM signal. Furthermore, electromagnetic interference degrades transmitter performance, increases the bit error rate, and affects broadcast clarity and reliability. In complex outdoor environments, this interference problem is further exacerbated, reducing the overall performance of the transmitter and the user experience. To address these issues, this invention uses a drive component located on the external structure of the transmitter. When the drive component needs to be activated, the servo motor is started. Driven by a servo motor, the fourth bevel gear rotates, which in turn drives the third bevel gear to rotate. Under the action of the drive rod, the second and first bevel gears rotate, which in turn drives the lead screw to rotate. This significantly improves the signal quality and overall performance of the transmitter, making audio signal transmission more stable, greatly reducing distortion and noise, and optimizing the stability and coverage of the FM signal. This ensures clear and reliable broadcast signals. At the same time, the bit error rate is reduced, further enhancing the performance and reliability of the transmitter. Especially in complex outdoor environments, the transmitter's anti-interference capability is significantly enhanced, enabling it to better adapt to various harsh conditions, ensuring the high quality and continuity of broadcast services, greatly improving the user experience, and achieving a higher level of overall performance and stability, meeting the high standards required for outdoor broadcasting.
[0008] Preferably, the sliding assembly includes two square slide rails fixed to the inner wall of the assembly slot. Roller mounting plates are fixed to both sides of the power amplifier module. Two front rollers are fixed to one side of each roller mounting plate, and two rear rollers are fixed to the other side. This sliding assembly design allows for quick and smooth installation and removal of the power amplifier module. The cooperation between the square slide rails and the front and rear rollers ensures precise positioning and smooth sliding of the module within the assembly slot, reducing mechanical wear caused by frequent disassembly and assembly. Furthermore, this design simplifies the installation process of the power amplifier module, reduces reliance on specialized tools and complex operations, improves maintenance efficiency, shortens equipment downtime, and further enhances the reliability and maintainability of the transmitter, making it more suitable for rapid deployment and flexible adjustment in complex outdoor environments.
[0009] Preferably, a motor partition is fixed to one side of the machine body, and a partition door is rotatably connected to one side of the motor partition. Both the motor partition and the partition door are made of copper, and a magnet is fixed to one side of the partition door. This design, using copper for the motor partition and the partition door, effectively shields electromagnetic interference, preventing electromagnetic noise generated by the servo motor from affecting the transmitter's internal circuitry and signal transmission. The magnet design of the partition door enhances the door's sealing performance, further isolating electromagnetic interference, while ensuring stable closing and rapid opening of the door.
[0010] Preferably, a latching plate is fixed to one side of the partition rotating door, and a latching head is fixed to one end of the latching plate. A latching groove is provided on one side of the motor partition. By setting a latching plate and a latching head on one side of the partition rotating door and providing a latching groove on the motor partition, the quick locking and unlocking function of the partition rotating door is realized. This design allows the partition rotating door to be firmly fixed to the motor partition, effectively preventing accidental opening of the door due to vibration or external force, thereby enhancing the sealing and stability of the equipment.
[0011] Preferably, the power amplifier module has a square gripping slot on one side, and the inner wall of the square gripping slot has an inclined groove. By providing a square gripping slot on one side of the power amplifier module and an inclined groove on the inner wall of the gripping slot, a more convenient operation method is provided for the installation and disassembly of the power amplifier module. The square gripping slot is easy for tools or hands to grasp, while the inclined groove can guide the grasping tools or fingers to be inserted and pulled out more smoothly, reducing friction and resistance during installation and disassembly. This design not only improves the efficiency of power amplifier module installation and disassembly and reduces the difficulty of operation, but also reduces the wear and tear on the module surface caused by frequent installation and disassembly. Beneficial effects
[0012] 1.

Furthermore, the weight of the equipment increases transportation costs and installation difficulty, especially in remote areas or locations with poor transportation, where the transportation and installation process is time-consuming and labor-intensive. This difficulty in relocation not only reduces the transmitter's practicality but also increases the investment of manpower and resources, limiting its outdoor application. To address the challenges of wide applicability and rapid response in various scenarios, this invention employs a convenient mobile structure, significantly enhancing its flexibility and responsiveness in outdoor environments. The device can be easily moved and redeployed across complex terrains such as mountains, hills, or temporary event sites without relying on multiple personnel or lifting equipment, greatly improving installation and adjustment efficiency. Simultaneously, it reduces transportation costs and installation difficulty, especially in remote areas or locations with poor transportation, enabling rapid deployment and minimizing manpower and material costs. Furthermore, the device's lightweight and portability enhance its practicality, allowing for wider application in various outdoor scenarios, meeting broadcasting needs in different environments, and improving overall operational efficiency and service quality.

The servo motor generates electromagnetic noise during operation, which enters the transmitter's circuitry through electromagnetic induction or conduction, interfering with the transmission and processing of digital audio signals. This interference leads to audio signal distortion, noise, and even affects the stability and coverage of the FM signal. Furthermore, electromagnetic interference degrades transmitter performance, increases the bit error rate, and affects broadcast clarity and reliability. In complex outdoor environments, this interference problem is further exacerbated, reducing the overall performance of the transmitter and impacting user experience. To address these issues, this invention employs a drive component located on the external structure of the transmitter, significantly improving signal quality and overall performance. Audio signal transmission is more stable, distortion and noise are greatly reduced, and the stability and coverage of the FM signal are optimized, ensuring clear and reliable broadcast signals.

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation
[0027] Reference Figure 1-8 A 3KW FM digital audio broadcast transmitter includes a body 1. A component slot 101 is provided on one side of the body 1. A power amplifier module 102 is provided on the inner wall of the component slot 101. The power amplifier module 102 is slidably connected to the inner wall of the component slot 101 via a sliding component. A snap-fit component slot 103 is provided on the inner wall of the component slot 101. A snap-fit slider slot 104 is provided on the inner wall of the snap-fit component slot 103. Two snap-fit shafts 105 are provided on the inner wall of the snap-fit component slot 103. Snap-fit slider blocks 106 are fixed at both ends of the two snap-fit shafts 105. The snap-fit slider blocks 106 are slidably connected to the inner wall of the snap-fit slider slot 104. Springs 107 are fixed on both sides of the snap-fit slider blocks 106. The other end of the springs 107 is fixed to the inner wall of the snap-fit slider slot 104. A snap-fit seat 108 is fixed on one side of the power amplifier module 102. In existing technologies, 3KW FM digital audio broadcast transmitters used in outdoor scenarios require frequent switching of power amplifier modules with different power levels depending on the environment. This leads to wear and tear on the equipment. Outdoor environments are complex and varied, such as mountainous areas, plains, or urban edges. Different scenarios have significantly different signal coverage and power requirements, necessitating constant disassembly and replacement of power amplifier modules. This increases the risk of mechanical wear and electrical failures, affecting equipment performance and lifespan. Furthermore, the disassembly and assembly process requires professional technicians, increasing maintenance costs and time, limiting the transmitter's stability and reliability, and impacting its long-term efficient operation in complex outdoor environments. To address these issues, this invention adopts a convenient disassembly and replacement structure. When it is necessary to... When replacing the power amplifier module 102, the sliding component allows the power amplifier module 102 to slide out without being forcibly pulled out of the component slot 101. Instead, it slides out with a certain gap from the component slot 101. The power amplifier module 102 then drives the latching seat 108, causing the latching seat 108 to disengage from the two latching seats 108's limiting position. During this dragging process, the two latching shafts 105, under the action of force, drive the two latching sliding blocks 106 to slide. After the latching seat 108 is completely disengaged from its limiting position, the two latching shafts 105 return to their initial position under the action of the spring 107. After inserting the new power amplifier module 102, the latching seat 108 can be directly inserted between the two latching shafts 105 to complete the replacement.
[0028] The bottom of the body 1 is provided with a bearing sliding groove 2. A first support plate 201 and a second support plate 202 are fixed to the inner wall of the bearing sliding groove 2. A lead screw 203 is rotatably connected to the top of the first support plate 201, and the other end of the lead screw 203 is rotatably connected to the bottom of the second support plate 202. An X-shaped bearing plate 204 is threaded onto the surface of the lead screw 203. The lead screw 203 is driven to rotate by a drive assembly. A caster wheel 205 is fixed to the bottom of the X-shaped bearing plate 204. In the prior art, 3KW FM band digital audio broadcast transmitters, due to their large size and heavy weight, bring many inconveniences to outdoor work. These transmitters usually need to be installed in a fixed location, and moving them requires multiple people or the use of lifting equipment, greatly limiting their flexibility. In complex and changeable outdoor environments, such as mountains, hills, or temporary activity sites, the need for frequent relocation is difficult to meet, resulting in low efficiency in equipment deployment and adjustment. Furthermore, the weight of the equipment increases transportation costs and installation difficulty, especially in remote areas or places with inconvenient transportation, where transportation and installation are time-consuming and labor-intensive. This difficulty in movement not only reduces… The practicality of the transmitter also increases the investment of manpower and resources, limiting its widespread application and rapid response capability in outdoor scenarios. To address these issues, this utility model adopts a convenient mobile structure. When the body 1 needs to be moved, the drive assembly is activated to drive the lead screw 203 to rotate, causing the X-shaped support plate 204 to move downwards, so that the casters 205 make full contact with the ground and support the power amplifier module 102. At this time, the component slot 101 can be moved by pushing it. After moving to the designated location, the drive assembly is activated again to drive the X-shaped support plate 204 to rotate, causing the lead screw 203 to rise, and the casters 205 to leave the ground, thus completing the movement.
[0029] The drive assembly includes a first bevel gear 4, which is fixed to the top of the lead screw 203. A support block 403 is fixed to the inner wall of the bearing sliding groove 2. A drive rod 402 is rotatably connected through one side of the support block 403. A second bevel gear 401 is fixed to one end of the drive rod 402, and a third bevel gear 404 is fixed to the other end. The second bevel gear 401 meshes with the surface of the first bevel gear 4, and a fourth bevel gear 405 meshes with the surface of the third bevel gear 404. The fourth bevel gear 405 is driven to rotate by a servo motor 406, which is fixed to one side of the machine body 1. In existing technologies, placing a servo motor inside a 3KW FM digital audio broadcast transmitter can significantly interfere with the transmitter's signal quality. The servo motor generates electromagnetic noise during operation, which enters the transmitter's circuitry through electromagnetic induction or conduction, interfering with the transmission and processing of digital audio signals. This interference can lead to audio signal distortion, noise, and even affect the stability and coverage of the FM signal. Furthermore, electromagnetic interference can reduce transmitter performance, increase the bit error rate, and affect the clarity and reliability of the broadcast. In complex outdoor environments, this interference problem is further exacerbated, reducing the overall performance of the transmitter and the user experience. To address these issues, this invention uses a drive assembly located on the external structure of the transmitter. When the drive assembly needs to be activated, the servo motor 406 is started. Driven by the servo motor 406, the fourth bevel gear 405 rotates, which in turn drives the third bevel gear 404 to rotate. Under the action of the drive rod 402, the second bevel gear 401 and the first bevel gear 4 rotate, thereby driving the lead screw 203 to rotate.
[0030] The sliding assembly includes two square slide rails 3, which are fixed to the inner wall of the component slot 101. Both sides of the power amplifier module 102 are fixed with pulley mounting plates 301. Two front pulleys 302 are fixed to one side of the pulley mounting plate 301, and two rear pulleys 303 are fixed to the other side. This sliding assembly design allows for quick and smooth installation and removal of the power amplifier module. The cooperation between the square slide rails and the front and rear pulleys ensures precise positioning and smooth sliding of the module within the component slot, reducing mechanical wear caused by frequent disassembly and assembly. Furthermore, this design simplifies the installation process of the power amplifier module. This design reduces reliance on specialized tools and complex operations, improves maintenance efficiency, shortens equipment downtime, and further enhances the transmitter's reliability and maintainability, making it more suitable for rapid deployment and flexible adjustment in complex outdoor environments. A motor partition 5 is fixed to one side of the main body 1, and a partition door 501 is rotatably connected to one side of the motor partition 5. Both the motor partition 5 and the partition door 501 are made of copper, and a magnet is fixed to one side of the partition door 501. This design, using copper for the motor partition and the partition door, effectively shields against electromagnetic interference, preventing electromagnetic noise generated by the servo motor from affecting the transmitter. The internal circuitry and signal transmission, along with the magnet design of the partition rotating door, enhance the door's sealing performance, further isolating electromagnetic interference while ensuring stable closing and rapid opening. A latching plate 6 is fixed to one side of the partition rotating door 501, with a latching head 601 fixed to one end. A latching groove 602 is provided on one side of the motor partition 5. By setting a latching plate and latching head on one side of the partition rotating door and providing a latching groove on the motor partition, the rapid locking and unlocking function of the partition rotating door is achieved. This design allows the partition rotating door to be securely fixed to the motor partition, effectively preventing accidental opening due to vibration or external force. This enhances the sealing and stability of the equipment. A square gripping groove 7 is provided on one side of the power amplifier module 102, and an inclined groove is provided on the inner wall of the square gripping groove 7. By providing a square gripping groove on one side of the power amplifier module and setting an inclined groove on the inner wall of the gripping groove, a more convenient operation method is provided for the installation and disassembly of the power amplifier module. The square gripping groove is easy for tools or hands to grip, while the inclined groove can guide the gripping tools or fingers to insert and pull out more smoothly, reducing friction and resistance during installation and disassembly. This design not only improves the efficiency of power amplifier module installation and disassembly and reduces the difficulty of operation, but also reduces the wear caused to the module surface by frequent installation and disassembly.
[0031] The working principle of this utility model is as follows: When the power amplifier module 102 needs to be replaced, under the action of the sliding component, the power amplifier module 102 does not need to be forcibly pulled out of the component slot 101, but slides out with a certain gap from the component slot 101. Next, the power amplifier module 102 drives the latching seat 108, causing the latching seat 108 to disengage from the two latching seats 108's limiting position. During the dragging process, the two latching shafts 105 drive the two latching sliding blocks 106 to slide under the action of force. After the latching seat 108 is completely disengaged from the limiting position, under the action of the spring 107, the two latching shafts 105 return to their initial position. After the new power amplifier module 102 is inserted, the latching seat 108 is simply inserted between the two latching shafts 105 to complete the replacement. When the machine body 1 moves, the drive assembly is activated to drive the lead screw 203 to rotate, causing the X-shaped support plate 204 to move downwards, so that the caster wheel 205 makes full contact with the ground and supports the power amplifier module 102. At this time, the push component slot 101 can be moved. After moving to the designated location, the drive assembly is activated again to drive the X-shaped support plate 204 to rotate, causing the lead screw 203 to rise, and the caster wheel 205 to leave the ground, thus completing the movement. When the drive assembly needs to be activated, the servo motor 406 is activated. Under the drive of the servo motor 406, the fourth bevel gear 405 rotates, which in turn drives the third bevel gear 404 to rotate. Under the action of the drive rod 402, the second bevel gear 401 and the first bevel gear 4 rotate, thereby driving the lead screw 203 to rotate.
[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
