Description

Technical Field

[0001] The utility model relates to the technical field of power amplifiers, in particular to a radio power amplifier. Background Art

[0002] Power amplifier is abbreviated as power amplifier. It generally refers to the most basic equipment in the audio system, commonly known as "loudspeaker". Its task is to amplify the weak electrical signal from the signal source (from the mixer in professional audio systems) to drive the speaker to produce sound. It can also refer to other devices that perform power amplification. The power amplifier is the largest family of various audio equipment. Its main function is to amplify the weak signal input from the sound source equipment and generate a large enough current to drive the speaker to reproduce the sound. Due to considerations of power, impedance, distortion, dynamics, different usage ranges and control adjustment functions, different power amplifiers are also different in internal signal processing, circuit design and production technology.

[0003] For example, the Chinese patent "CN219068728U" discloses a power amplifier, which proposes that: a mounting mechanism is installed inside the housing of the power amplifier; wherein, both sides of the sealing end cover are slidably connected with fixed bayonet pins, and the fixed bayonet pins are sleeved with a second set of springs matching the fixed bayonet pins. The utility model realizes a power amplifier through the mutual cooperation between the housing of the power amplifier, the sealing end cover, the mounting mechanism and the heat dissipation fan. Not only does it adopt an overhead installation of the power amplifier, which can greatly increase the heat dissipation effect of the power amplifier, thereby ensuring the stable operation of the power amplifier, but it is also convenient to disassemble and assemble the end cover of the power amplifier. Therefore, when the internal circuit board of the power amplifier is damaged, it is convenient to maintain or replace it, thereby improving the practicality of the power amplifier of the utility model.

[0004] It can be seen from the above-mentioned device that although the above-mentioned device provides a method for convenient repair and replacement when damaged, the applicant believes that the following defects still exist:

[0005] In order to prevent dust and foreign matter from entering during use, the existing power amplifiers have small heat dissipation holes, and the heat dissipation effect is not obvious. In addition, in daily use, the internal circuit boards are easily damaged or shifted when hit by objects or bumped during movement due to the lack of protective devices. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-2 The radio power amplifier comprises a power amplifier 1, a protection component 2 and a protection plate component 3. A plurality of bar-shaped protrusions are arranged below the power amplifier 1 for enhancing the model. A plurality of heat dissipation holes 15 are arranged above the power amplifier 1. The heat dissipation holes 15 can effectively dissipate heat to prevent the power amplifier 1 from overheating. Two interfaces 11 are arranged on both sides of the back of the power amplifier 1. A display screen 12 is arranged on one side of the front of the power amplifier 1. A control button 14 is arranged on the other side of the front of the power amplifier 1. An indicator light 13 is arranged on the front of the power amplifier 1. The display screen 12 and the control button 14 provide convenience for human-computer interaction. The indicator light 13 can indicate the working status of the power amplifier 1.

[0032] See also Figure 4The protection component 2 includes a spring base 21, which is fixedly installed at the four corners above the power amplifier 1. The outer wall of the spring base 21 is sleeved with a support spring 22. The outer walls of the two support springs 22 on the same side are fixedly connected with a pad 23. Two mounting plates 211 are arranged on both sides above the pad 23. A plurality of magnets 212 are arranged inside the mounting plate 211. The outer walls of the pads 23 on both sides are fixedly connected with connecting rods 24. Two sliding bases 25 are movably installed on the outer wall of the connecting rod 24. The outer walls of the two sliding bases 25 are fixedly connected with shock absorbing springs. Spring 210, a first limiting rod 26 is fixedly connected to the inner wall of the sliding base 25, a rotating plate 27 is movably installed on the outer wall of the first limiting rod 26, a second limiting rod 28 is movably installed inside the rotating plate 27, and the second limiting rod 28 is fixedly installed inside the rotating plate base 29, and the rotating plate base 29 is fixedly installed above the power amplifier 1. The main function of this protection component 2 is to provide shock absorption and limiting effects to ensure that the power amplifier 1 can remain stable when subjected to external impact or vibration, and to prevent internal components from being displaced or damaged. Specifically, when external impact or vibration acts on the power amplifier 1, the support spring 22 and the shock absorbing spring 210 can absorb and disperse the impact force, thereby reducing damage to internal components. At the same time, the first limiting rod 26 and the second limiting rod 28 can limit the rotating plate 27 so that it can only move within a certain range to prevent it from swinging excessively or shifting.

[0033] See also Figure 3-5The protective plate assembly 3 includes an outdoor protective plate 31 and a hollow breathable protective plate 33. A plurality of magnetic blocks 32 are arranged at the four corners of the inner wall of the outdoor protective plate 31. The plurality of magnetic blocks 32 are symmetrically arranged with the magnet 212 and attract each other. There are two replaceable types of the protective plate assembly 3, one is the outdoor protective plate 31, and the other is the hollow breathable protective plate 33. Both protective plates are installed by arranging magnetic blocks 32 on the inner wall to adsorb the magnet 212. A plurality of air holes are opened in the outer wall matrix of the hollow breathable protective plate 33, and a dustproof net is arranged inside the air hole. The outdoor protective plate 31 is mainly suitable for outdoor environments. It can provide a certain protection to prevent the external environment from damaging the power amplifier 1. The hollow breathable protective plate 33 is mainly suitable for scenes that require ventilation and heat dissipation. The several air holes opened in the outer wall matrix can provide good ventilation performance. At the same time, the internal dustproof net can prevent dust from entering and keep the interior clean. The outdoor use protective plate 31 and the hollow breathable protective plate 33 are both made of aluminum-plastic plate. The aluminum-plastic plate has good protective performance, which is related to its material composition and structure. First, the surface layer of the aluminum-plastic plate is a stretched aluminum layer, which has excellent weather resistance, fire resistance and moisture resistance, can effectively resist ultraviolet rays and oxidation, and is not easy to be eroded and damaged. Secondly, the core layer of the aluminum-plastic plate is a plastic material, which has good buffering and shock resistance, can effectively absorb and disperse external pressure and impact force, and protect the internal aluminum layer from damage. In addition, the aluminum-plastic plate is processed using special adhesives and processes, has good adhesion and stability, and is not easy to fall off, crack or deform.

[0034] Working principle: First, when used indoors, the hollow breathable protective plate 33 can be installed above the magnet 212 through the magnetic block 32 below. The hollow breathable protective plate 33 is provided with a number of air holes, which can more effectively help the air in the heat dissipation hole 15 to be discharged, and the dustproof net in the air hole can effectively prevent dust or foreign matter from entering the power amplifier 1 through the heat dissipation hole 15. After placement, if a heavy object falls on the top of the power amplifier 1, the hollow breathable protective plate 33 blocks the heavy object. When the heavy object falls, the hollow breathable protective plate 33 is pressed down by gravity, and the hollow When the breathable protective plate 33 is pressed down, it drives the pads 23 on both sides to be pressed downward. When the pads 23 on both sides are pressed down, the support springs 22 first support and dampen them to weaken the downward force, and while the pads 23 are pressed down, the rotating plates 27 on both sides rotate when the connecting rod 24 moves downward, and the two rotating plates 27 rotate inward at the same time. The damping springs 210 provide support force to the bases of the two rotating plates 29, so that the downward pressure of the rotating plates 27 on both sides is blocked, and support force is provided to the hollow breathable protective plate 33, thereby reducing the downward pressure of heavy objects on the power amplifier 1 to prevent damage to the power amplifier and affect normal use.

[0035] Secondly, when outdoor use is required, the hollow breathable protective plate 33 is replaced with an outdoor protective plate 31. Since the outdoor protective plate is trapezoidal, rainwater will flow downward along the inclined edge of the outdoor protective plate 31 in rainy and snowy weather to prevent rainwater from falling on the surface of the power amplifier 1 and causing damage to it. Since the outdoor air circulation and heat dissipation are stronger than those indoors, the outdoor protective plate 31 is not provided with ventilation holes and has stronger protection than the hollow breathable plate 33, and is more suitable for use in outdoor environments.
