Description

Technical Field

[0001] This utility model relates to the field of communication radio technology, specifically a multi-mode ground aviation communication radio. Background Art

[0002] Communication aims to transmit information from a sender to a receiver at another point in time and space. A communication system refers to the sum of all equipment and transmission media that realize this information exchange process. Aviation communication, as the name suggests, is communication related to aviation. It refers to all information transmission and exchange used in aircraft operations, mainly involving air-to-ground communication between aircraft and the ground, air-to-air communication between aircraft, and air-to-sea communication between aircraft and surface ships / submarines. It also covers ground communication between ground stations or ground / air and space satellite communication. Aviation communication equipment is an airborne device that realizes wireless communication functions, meets the specified performance requirements, and has been verified in use. Aviation communication equipment is responsible for the function of aircraft communicating with the outside world.

[0003] In existing technologies, the ionosphere is a crucial reflective layer in shortwave communication. Its electron density varies with diurnal cycles, seasons, and solar activity, directly affecting the propagation characteristics of shortwave signals, including reflection paths, attenuation, and phase changes. To address the impact of diurnal ionospheric variations on communication quality, radio stations typically adjust signal frequencies periodically at fixed times, such as around sunrise and sunset. Ground-based aviation radio stations may switch to different frequencies and communication modes at different times to meet varying communication needs, such as VHF voice communication and AHF... CARS data link communication, VDL mode 2 data link communication, etc., and in certain special circumstances, such as frequency allocation plans, frequency reuse strategies, or for compatibility with other systems, radios may switch frequencies according to a predetermined schedule. Usually, staff need to switch frequency modes regularly for transmission and reception. Manual switching is not only inefficient, but also prone to human error, especially in emergency or high-pressure working environments. However, in actual operation, due to various factors such as operator fatigue, lack of concentration, or unfamiliarity with the equipment, incorrect switching modes may occur, which in turn affects communication quality and flight safety.

[0004] The purpose of this invention is to provide a multi-mode ground aviation communication radio to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-mode ground aviation communication radio, including a radio housing. An adjustment assembly is installed inside the radio housing. The adjustment assembly includes a motor mounted on the inner wall of the radio housing. One end of the motor is rotatably connected to a first rotating shaft. One end of the first rotating shaft is connected to a protrusion. A slide rod is connected to the outer wall of the top of the protrusion. A first spring is sleeved on the bottom of the slide rod. A slider is mounted on one side of the outer wall of the slide rod. The slider is slidably connected to a guide rail. A connecting rod is mounted on one side of the guide rail. A first pawl is connected to the top of the connecting rod. A first ratchet is engaged with the bottom of the first ratchet. A first adjustment knob is fixedly connected to one side of the outer wall of the motor. A second rotating shaft is mounted in the middle of the first adjustment knob. A second adjustment knob is rotatably connected to the end of the second rotating shaft away from the first adjustment knob. A second ratchet is fixedly connected to the inner wall of the second adjustment knob. A mounting block is fixedly installed on the inner wall of the radio housing. A support rod is fixedly installed on one side of the outer wall of the mounting block. A spring-loaded assembly is installed on the inner wall of the first adjustment knob. A second pawl is fixedly connected to the outer wall of the spring-loaded assembly.

[0006] Furthermore, the spring-loaded assembly installed on the inner wall of the first adjustment knob includes a fixing rod fixedly connected to the inner wall of the first adjustment knob, a second spring sleeved on the outside of the fixing rod, and a sleeve sleeved on the outside of the second spring.

[0007] Furthermore, one end of the second spring is fixedly connected to the outer wall of the fixed rod, and the other end of the second spring is fixedly connected to the inner wall of the sleeve.

[0008] Furthermore, the support rod is C-shaped, and a baffle is installed at the shorter end of the support rod. The baffle is arc-shaped, and the inner wall of the baffle abuts against the outer wall of the second pawl. The inner wall of the baffle is evenly covered with anti-slip texture.

[0009] Furthermore, a speaker is installed on one side of the outer wall of the radio box, and a display screen is also installed on the same side of the outer wall of the radio box. Multiple small holes are evenly distributed on the surface of the speaker.

[0010] Furthermore, a cooling fan is installed on one side of the outer wall of the radio box, and a ventilation opening is opened on the outer wall of the radio box opposite to the cooling fan, with the cooling fan connected to the ventilation opening.

[0011] Furthermore, the bottom of the radio box is equipped with multiple legs, four in total. The four legs are rectangular at the bottom of the radio box, and each leg has a protective pad at its bottom. The protective pad is made of non-slip material.

[0012] Furthermore, one end of the second pawl is far from the second ratchet, and after the second pawl abuts against the support rod, the second pawl and the second ratchet are engaged.

[0013] Compared with existing technologies, the advantages of this invention are as follows: Precise time interval control can be achieved using the adjustment component. Regular multi-mode signal frequency adjustment is performed based on the cyclical changes of the day. This includes, but is not limited to, switching to other idle frequency bands to ensure smooth communication when the device faces frequency congestion during fixed time periods. The various regularly adjusted modes ensure the accuracy and consistency of signal adjustment, with each mode ensuring the signal is in optimal condition at every point in time. This avoids signal distortion or instability caused by mode mismatch due to time errors, improving signal quality and stability. Compared to traditional manual adjustment methods, it eliminates the need for constant operator monitoring, saving unnecessary manpower and improving work efficiency. Attached Figure Description

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0027] Please see Figure 1 - Figure 7 This utility model provides a technical solution for a multi-mode ground aviation communication radio:

[0028] In the embodiments of this utility model, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The system includes a radio housing 1, inside which an adjustment assembly 2 is installed. The adjustment assembly 2 includes a motor 201 mounted on the inner wall of the radio housing 1. One end of the motor 201 is rotatably connected to a first rotating shaft 202. One end of the first rotating shaft 202 is connected to a protrusion 203. A slide rod 204 is connected to the outer wall of the top of the protrusion 203. A first spring 205 is sleeved on the bottom of the slide rod 204. A slider 206 is mounted on one side of the outer wall of the slide rod 204. The slider 206 is slidably connected to a guide rail 207. A connecting rod 208 is mounted on one side of the guide rail 207. A first pawl 209 is connected to the top of the connecting rod 208. The bottom end of 09 is engaged with a first ratchet 210. A first adjustment knob 211 is fixedly connected to one side of the outer wall of the motor 201. A second rotating shaft 212 is installed in the middle of the first adjustment knob 211. A second adjustment knob 213 is rotatably connected to one end of the second rotating shaft 212 away from the first adjustment knob 211. A second ratchet 214 is fixedly connected to the inner wall of the second adjustment knob 213. A mounting block 216 is fixedly installed on the inner wall of the radio box 1. A support rod 215 is fixedly installed on one side of the outer wall of the mounting block 216. A spring-loaded assembly 3 is installed on the inner wall of the first adjustment knob 211. A second pawl 217 is fixedly connected to the outer wall of the spring-loaded assembly 3.

[0029] It should be noted that the first rotating shaft 202 is fixedly connected to the part of the protrusion 203 near the edge. Therefore, when the first rotating shaft 202 starts to rotate, the protrusion 203 will repeatedly push the slide bar 204 up and down. The mounting block 216 is fixedly connected to the inner wall of the radio box 1, and the mounting block 216 and the slide bar 204 are slidably connected.

[0030] See Figure 4 , Figure 7 The spring-loaded assembly 3 installed on the inner wall of the first adjustment knob 211 includes a fixed rod 301 fixedly connected to the inner wall of the first adjustment knob 211, a second spring 302 sleeved on the outside of the fixed rod 301, a sleeve 303 sleeved on the outside of the second spring 302, one end of the second spring 302 fixedly connected to the outer wall of the fixed rod 301, and the other end of the second spring 302 fixedly connected to the inner wall of the sleeve 303.

[0031] It should be noted that during the rotation of the sleeve 303 driven by the second pawl 217, the second spring 302 is mainly subjected to torque. The torque will cause the second spring 302 to undergo torsional deformation. As the torque increases, the torsional angle of the second spring 302 will gradually increase until it reaches its maximum bearing capacity. When the force is stopped, the second spring 302 will use the previously stored energy to drive the sleeve 303 to rebound, so that the second pawl 217 no longer engages the second ratchet 214.

[0032] participate Figure 6 The support rod 215 is C-shaped, and a baffle is installed at the shorter end of the support rod 215. The baffle is arc-shaped, and the inner wall of the baffle abuts against the outer wall of the second pawl 217. The inner wall of the baffle is evenly covered with anti-slip texture.

[0033] It should be noted that the anti-slip texture can effectively prevent the second pawl 217 from slipping or deviating from the track during movement, thereby ensuring the normal operation of the system.

[0034] See Figure 1 A speaker 4 is installed on one side of the outer wall of the radio box 1, and a display screen 5 is also installed on the same side of the outer wall of the radio box 1. Multiple small holes are evenly distributed on the surface of the speaker 4.

[0035] It should be noted that display screen 5 allows staff to visually observe the radio's operating status.

[0036] See Figure 1 A cooling fan 6 is installed on one side of the outer wall of the radio box 1. A ventilation opening is opened on the outer wall of the radio box 1 opposite to the cooling fan 6. The cooling fan 6 is connected to the ventilation opening.

[0037] It should be noted that both the inner wall of the cooling fan 6 and the inner wall of the vent are equipped with dustproof plates. The dustproof plates can effectively reduce dust entering the equipment while ensuring good heat dissipation performance.

[0038] See Figure 1 The bottom of the radio box 1 is equipped with multiple legs 7. There are four legs 7 in total. The four legs 7 are rectangular at the bottom of the radio box 1. Each leg 7 has a protective pad at the bottom. The protective pad is made of non-slip material.

[0039] It should be noted that the four support legs 7 effectively distribute the weight of the radio, reducing the risk of swaying or tipping due to instability. In addition, the protective pads effectively distribute the weight of the radio, reducing the risk of swaying or tipping due to instability. The protective pads also have a certain cushioning effect, which can absorb the impact of external vibrations on the radio and protect the internal components of the radio from damage.

[0040] Working principle: When the motor 201 starts, it drives the first rotating shaft 202 to rotate. When the first rotating shaft 202 rotates, it drives the protrusion 203 to push the slide rod 204 to move up and down reciprocally. Through the connection between the slide rod 204 and the first spring 205, the first spring 205 can store force when it is subjected to force. When the force is released, it rebounds and causes the slide rod 204 to fall quickly. At the same time, a slider 206 is installed on one side of the outer wall of the slide rod 204. The slider 206 is slidably connected to the guide rail 207. When the slide rod 204 is lifted, it pushes the slider. 206 drives the guide slide rail 207, which in turn pushes the connecting rod 208. A first pawl 209 is fixedly connected to the top of the connecting rod 208. Due to the movement of the connecting rod 208, the first pawl 209 moves downwards, engaging with the teeth on the outer wall of the first ratchet 210, thus pushing the first ratchet 210 forward and driving the fixedly connected first adjusting knob 211 to perform the first adjustment. Furthermore, when the first adjusting knob 211 rotates, the second pawl 217, installed on the inner wall of the first adjusting knob 211 via the spring-loaded assembly 3, also… It will rotate forward until the protrusion of the second pawl 217 abuts against the support plate installed at one end of the support rod 215. After abutting, the spring-loaded assembly 3 drives the second pawl 217 downward to mesh with the teeth provided on the outer wall of the second ratchet 214. Then, it drives the second adjustment knob 213 connected to the outer wall of the second ratchet 214 to perform the second step of adjustment. During this process, the spring-loaded assembly 3 includes a fixed rod 301 that is fixedly connected to the first adjustment knob 211. The fixed rod 301 can drive the entire spring-loaded assembly 3 along with the first adjustment knob 211. The movement of 1 actuates the second pawl 217. The second spring 302 is sleeved on the outside of the fixed rod 301. The second spring 302 deforms as the second pawl 217 drives the sleeve 303 to rotate. By storing the force during deformation, when the second pawl 217 is no longer resisted by the baffle installed at one end of the support rod 215, it can drive the second pawl 217 to rebound and return to its original position, so that the second pawl 217 no longer engages with the second ratchet 214. Instead, it will only lock and rotate to adjust the radio signal when it is fixed and rotated to a specific position.

[0041] It should be noted that the function of selecting the desired frequency band by rotating the first adjustment knob 211 and the second adjustment knob 213 is usually achieved through internal tuning and control circuits in multi-mode ground aviation communication radios. These circuits include: Knob components: The knob is the physical interface for interaction with the radio; rotating it generates a mechanical signal, which is converted into an electrical signal; Encoder or potentiometer: An encoder or potentiometer is usually connected inside the knob. The encoder converts the knob's rotation angle into a digital signal, while the potentiometer generates a changing voltage signal by altering the resistance value. These signals represent the frequency band or frequency selected by the operator; Control circuit: The control circuit is one of the core components inside the radio. It receives the electrical signal from the encoder or potentiometer and adjusts the radio's operating parameters based on this signal; Tuning circuit: The tuning circuit is responsible for selecting and receiving specific frequency bands or frequency signals. Based on the instructions from the control circuit, it adjusts the parameters of components such as inductors and capacitors in the circuit, thereby achieving the selection of the desired frequency band or frequency.

[0042] This is existing technology and will not be elaborated further.
