[0031] See also Figure 1 and Figure 2 , Figure 1 Provides the enclosure structure diagram of the amplifier plug-in box. Figure 2 An exploded view of the bottom plate 2 is provided. The present application provides an amplifier plug-in box, which mainly includes a shell, the shell includes a side plate 100 and a bottom plate 200, the side plate 100 is arranged around the circumference of the bottom plate 200 to enclose a storage space, and the bottom plate 200 is provided with at least one through hole 210 connecting the storage space and the external environment and a group of ventilation components arranged corresponding to the through hole 210. The ventilation component includes a fan 310 and a connecting plate 320, the connecting plate 320 is hollowed out, the connecting plate 320 is located at one end of the through hole 210 away from the storage space and is detachably connected to the bottom plate 200; the fan 310 is located at one end of the through hole 210 facing the storage space and is fixedly connected to the connecting plate 320. Along the first direction, the through hole 210 is sleeved on the fan 310, wherein the first direction is the axial direction of the through hole 210.

[0032] In the above embodiment, the fan 310 is not directly connected to the bottom plate 200, but is detachably connected to the bottom plate 200 through the connecting plate 320. In this way, when the air duct and the fan 310 are covered with dust, the connecting plate 320 can be directly removed. Since the fan 310 is smaller than the through hole 210, the fan 310 can be directly taken out for cleaning. After cleaning, it can be reinstalled. Therefore, the amplifier plug-in box provided in the present application facilitates the cleaning of the fan 310 and the air duct at any time, ensuring smooth air duct.

[0033] Preferably, see Figure 2 In one embodiment, the ventilation assembly further includes a honeycomb panel 330, which is located on a side of the connecting plate 320 away from the bottom plate 200 and is fixedly connected to the connecting plate 320, and along the first direction, the projection of the fan 310 coincides with the projection of the honeycomb panel 330. The honeycomb panel 330 is provided with a plurality of ventilation holes with a diameter less than 5 mm, and the ventilation holes are used to connect the through hole 210 and the external environment.

[0034] Similarly, the honeycomb panel 330 is also connected to the connecting plate 320. Since there are multiple ventilation holes on the honeycomb panel 330, dust will accumulate on the honeycomb panel 330 over time, so they can be disassembled and cleaned together. The main function of the honeycomb panel 330 is to prevent larger foreign objects, such as paper scraps, from entering the fan 310 or even the chassis to affect the normal operation of internal electronic devices.

[0035] See also Figure 2In one embodiment, the ventilation assembly further includes a shielding mesh cover 340, which is located on the side of the connecting plate 320 away from the bottom plate 200 and is fixedly connected to the connecting plate 320, and the shielding mesh cover 340 is provided with a limiting groove 341, and the outer peripheral surface of the honeycomb panel 330 is clamped in the limiting groove 341 to limit the movement of the honeycomb panel 330 in the first direction.

[0036] In the above embodiment, the shielding mesh cover 340 is mainly used to prevent the honeycomb panel 330 from falling off the plug-in box. In order to reduce the overall quality, the honeycomb panel 330 is usually made of plastic, while the plug-in box is made of metal. Therefore, there is no part on the honeycomb panel 330 that is effectively connected to the bottom plate 200 or the connecting plate 320. The stability of the honeycomb panel 330 can only be ensured by limiting the position. The shielding mesh cover 340 plays such a role.

[0037] See also Figure 3 In one embodiment, the base plate 200 is provided with a first connecting hole, the connecting plate 320 is provided with a plurality of second connecting holes 322, the shielding mesh cover 340 is provided with a third connecting hole 342, and along the first direction, the first connecting hole, the first connecting hole, and the second connecting hole 322 of the base plate 200 are concentrically arranged and threadedly connected.

[0038] See also Figure 3 In one embodiment, along the second direction, the connecting plate 320 is provided with a shielding portion 325 along the outer peripheral surface direction of the through hole 210, the outer wall of the shielding portion 325 is in contact with the bottom plate 200, and the inner wall of the shielding portion 325 is in contact with the fan 310. The second direction is the radial direction of the through hole 210.

[0039] See also Figure 3 In one embodiment, the connecting plate 320 is provided with a plurality of second connecting portions 321 and a fourth connecting portion 323 (the first connecting portion and the third connecting portion are not named in the present application), the second connecting portion 321 is located on the outer side of the shielding portion 325 and is threadedly connected to the bottom plate 200, the fourth connecting portion 323 extends into the through hole 210 through the shielding portion 325 along the second direction, and the fan 310 is threadedly connected to the fourth connecting portion 323.

[0040] Specifically, in the above embodiment, the specific structure of the connecting plate 320 is as follows: it includes a shielding portion 325, a second connecting portion 321 and a fourth connecting portion 323, wherein the shielding portion 325 is a polygon or ring shape similar to the outer contour of the through hole 210. Since the through hole 210 needs to be larger than the fan 310, there will inevitably be a certain gap between the through hole 210 and the fan 310. The shielding portion 325 can be used to shield the gap, to isolate the gap from the external environment, and to prevent external debris from entering the plug box through the gap. The second connecting portion 321 has a second connecting hole 322, which is located outside the shielding portion 325. The second connecting portion 321 is used to connect with the bottom plate 200. The second connecting hole 322 is a threaded hole, and the connection method between the two is threaded connection. The fourth connecting portion 323 is located inside the shielding portion 325, and the fourth connecting portion 323 has a fourth connecting hole 324. The fan 310 can be fixedly connected to the fourth connecting portion 323 through the through hole 210, and the connection method is still threaded connection.

[0041] See also Figure 3 Preferably, in one embodiment, the connecting plate 320 is provided with a plurality of ribs 326, the ribs 326 pass through the hollow surface of the connecting plate 320, and the two ends of the ribs 326 are fixedly connected to the shielding portion 325. The main structure of the connecting portion is the shielding plate, which is easy to bend due to its large length and width, and the ribs 326 can strengthen the structural strength of the connecting plate 320.

[0042] See also Figure 5 , Figure 5 The structure of the wiper is shown. In one embodiment, the side plate 100 is provided with a shielding slot 110, and the shielding slot 110 is installed with shielding material. Specifically, the four side plates 100 around the plug box body are added with shielding design to meet the electromagnetic shielding requirements of various levels. The shielding material is mainly metal material.

[0043] Preferably, in one embodiment, the plug-in box further comprises a top plate, which is arranged opposite to the bottom plate 200 and is in contact with the outer peripheral surface of the side plate 100. A bracket is provided between the side plate 100 and the bottom plate 200, and between the side plate 100 and the top plate. The bracket is L-shaped, one end of the bracket is connected to the side plate 100, and the other end of the bracket is correspondingly fixedly connected to the bottom plate 200 or the side plate 100. The bracket can enhance the connection stability of the bottom plate 200, the top plate and the side plate 100, and enhance the reliability of the plug-in box, so that the application environment of the plug-in box can be expanded from the original fixed station to the vehicle environment.

[0044] Preferably, the whole machine structure adopts a minimalist plate design, which can complete the box frame assembly with only three types of parts, namely the bottom plate 200, the top plate and the side plate 100, while ensuring the electromagnetic shielding requirements, greatly reducing the number of parts and assembly efficiency.

[0045] Preferably, see Figure 1 In one embodiment, two groups of ventilation components are provided, and the two groups of ventilation components are respectively arranged at the two ends of the bottom plate 200. Figure 1 It can be found from the structure of the midsole plate 200 that the bottom plate 200 is provided with two through holes 210 for installing ventilation components. Two sets of ventilation components are installed on both sides of the bottom plate 200 to achieve a better ventilation effect.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
