Description

Technical Field

[0001] The utility model relates to the technical field of automotive power amplifiers, and specifically relates to an automotive power amplifier box with a dust-proof structure. Background Technique

[0002] An automotive power amplifier is an audio power amplifier in a vehicle audio system, also known as an automotive audio power amplifier. It is mainly used to enhance the power and sound quality of audio signals, ensuring that the sound can reach the ideal volume and sound quality effect in the automotive environment. The main function of the automotive power amplifier is to enhance the intensity of the audio signal through power amplification, so that the speaker can play a louder and clearer sound. This is achieved by calculating the power through the product of voltage and current. In the power amplifiers of existing automotive audio devices, the shape of the power amplifier housing is mostly a flat structure. When assembling the entire power amplifier, the circuit board and the radiator are usually assembled together first, and then parts such as the power amplifier housing and side plates are assembled.

[0003] In the existing power amplifier device, heat dissipation slots are generally opened on one side of the housing structure. During its use, dust easily enters the interior from the heat dissipation openings, increasing the risk of dust falling on electronic components, thereby disrupting the normal operation of the circuit control device. This will not only affect the service life of the automotive power amplifier, but may also cause corrosion of the main board inside the automotive power amplifier. For this reason, we propose an automotive power amplifier box with a dust-proof structure. Content of the Utility Model

[0004] This part of the content of the present application is used to briefly introduce the concepts, which will be described in detail in the following detailed implementation part.

[0005] The purpose of the utility model is to provide an automotive power amplifier box with a dust-proof structure to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An automotive power amplifier box with a dust-proof structure, including a main frame. A heat dissipation frame is arranged at the top of the main frame, and auxiliary heat dissipation slots are distributed at both ends of the main frame. The heat dissipation frame includes a frame plate, and screws are distributed around the frame plate. A card slot is opened on the top surface of the frame plate, and heat dissipation holes are opened inside the card slot. Sliding grooves are opened on both inner walls of the card slot, and a grid frame is attached to the inner walls of the sliding grooves.

[0010] Further, the cushion blocks are symmetrically distributed around the bottom end of the box body, and the frame material of the box body is alloy.

[0011] Further, the auxiliary heat dissipation groove includes a baffle, and an inner notch is opened at one end of the baffle. A side wire frame is attached to one end of the inner notch, a magnetic attraction frame is connected to one side of the side wire frame, and a fan frame is connected to the other side of the side wire frame.

The filter screen connected to the inner wall of the grid frame is relied on to keep filtering dust. At the same time, the attached filter is made of bamboo charcoal material and has a certain hygroscopicity. Cooperating with the filter screen can reduce the influence of environmental dust and moisture to a certain extent during the operation of the overall power amplifier device, and improve the stability and safety of use;

[0026] Hereinafter, the present disclosure will be described in detail with reference to the drawings and in combination with the embodiments.

[0027] The present utility model provides an automotive power amplifier box with a dust-proof structure as Figures 1-4 shown, which includes a main frame 1. A heat dissipation rack 2 is arranged at the top end of the main frame 1, and auxiliary heat dissipation grooves 3 are distributed at both ends of the main frame 1. The main frame 1 includes a box body 101, and cushion blocks 102 are distributed around the bottom end of the box body 101. A slot plate 103 is arranged at one end of the box body 101, and both sides of the box body 101 are fixedly connected to the auxiliary heat dissipation grooves 3;

[0028] To maintain the stability of the internal structure and placement during the process, as Figure 1 shown, this automotive power amplifier box is made of a box body 101 of alloy material, which can maintain the structural strength, provide stable installation and external protection for components such as the circuit board installed inside, and at the same time, rely on the pads 102 distributed around the bottom end to maintain stable placement and ensure stability during use.

[0029] As Figure 2 shown, the heat dissipation rack 2 includes a rack plate 201, and screws 202 are distributed around the rack plate 201. A card slot 203 is opened on the top surface of the rack plate 201, and heat dissipation holes 204 are opened inside the card slot 203. Sliding grooves 205 are opened on both inner walls of the card slot 203, and a grid rack 206 is attached to the inner wall of the sliding groove 205. Filter screens 207 are connected to the inner periphery of the inner wall of the grid rack 206, and filter sheets 208 are attached to the bottom surface of the filter screens 207;

[0030] To maintain the dust-proof function, as Figure 2 shown, this automotive power amplifier box is equipped with a rack plate 201 at the top of the box body 101. The rack plate 201 can be connected to the top end of the box body 101 through the screws 202 around it, which is convenient for disassembly and maintenance. The card slot 203 opened on the top surface of the rack plate 201 can be slidably clamped with the grid rack 206 in cooperation with the sliding groove 205, which is convenient for disassembly and replacement. The filter screens 207 connected to the inner wall of the grid rack 206 are relied on to filter dust. At the same time, the attached filter sheets 208 are made of bamboo charcoal material and have a certain hygroscopicity. In cooperation with the filter screens 207, the overall power amplifier device can reduce the influence of environmental dust and moisture to a certain extent during operation, improving the stability and safety of use.

[0031] As Figures 3-4 shown, the auxiliary heat dissipation groove 3 includes a baffle 301, and an inner notch 302 is opened at one end of the baffle 301. A side grid rack 303 is attached to one end of the inner notch 302, a magnetic adsorption frame 304 is connected to one side of the side grid rack 303, and a fan rack 305 is connected to the other side of the side grid rack 303;

[0032] Finally, to assist in the overall heat dissipation of the power amplifier, as Figures 3-4 shown, this box body 101 is provided with baffles 301 at both ends. By opening inner notches 302 for ventilation between the gaps formed by the baffles 301, the phenomenon of dust entering can be reduced. While further preventing dust by the inner side grid rack 303 on the inner wall, it cooperates with the fan rack 305 to assist in blowing out the internal heat for heat dissipation, and the entire side grid rack 303 can be installed and removed by magnetic adsorption through the magnetic adsorption frame 304.

[0033] In summary, when the automotive power amplifier box is in use, the box body 101 can be placed at the usage position first, and then it is used in connection with the wiring through the slot board 103. During use, the heat dissipation holes 204 arranged in the card slots 203 of the top shelf board 201 can discharge heat, and the dust on the top is intercepted by the filter screen 207. At the same time, the internal part and the bamboo charcoal filter sheet 208 can absorb a part of the moisture in the incoming air to keep the interior dry. The blower frames 305 on both sides of the box body 101 also operate synchronously, and the internal heat is blown out of the inner slot 302 through the blower frames 305 to complete auxiliary heat dissipation.
