Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric vehicle technology, specifically to an electric vehicle controller box. Background Technology
[0002] The electric vehicle controller is essentially the brain of the vehicle, controlling its starting, stopping, forward, and backward movements. However, due to the size limitations of electric vehicles, the controller lacks effective heat dissipation during riding, relying primarily on natural cooling. Furthermore, the controller needs to be waterproof to prevent short circuits caused by water ingress. However, waterproofing requires a perfect seal, which to some extent reduces the controller's heat dissipation efficiency.
[0003] Existing technology, such as publication number CN218851210U, provides an electric vehicle controller housing. The housing includes a main body, baffles, and a cover. The main body is a groove formed by two side plates and a bottom plate. Both the side plates and the bottom plate are rectangular, and their outer surfaces have parallel ventilation slots arranged along the groove axis. The baffle has multiple screw holes and ventilation holes on its edges. Bolts are used to fix the baffle to both ends of the groove, at which point the ventilation holes and ventilation slots are connected. The cover has sliding grooves on both sides, and guide rails are provided at the upper edges of the two side plates, allowing the sliding grooves to engage with the guide rails, thus fixing the cover to the housing. A spring-loaded pressing structure is also provided inside the housing to reinforce the connection between the controller and the housing. Ventilation slots are provided outside the housing, utilizing pressure difference to allow airflow to quickly pass through the ventilation slots during riding, cooling the housing. Waterproof materials are selectively added at the joints of various components to improve the housing's waterproof performance.
[0004] The current design incorporates multiple ventilation slots on the main body of the box, utilizing pressure difference to allow airflow to pass quickly through these slots, accelerating the removal of heat from the box and improving cooling efficiency. However, in actual use, dust easily accumulates in the ventilation slots over extended periods, reducing airflow and consequently decreasing heat dissipation. Therefore, we propose an electric vehicle controller box. Utility Model Content
[0005] The purpose of this utility model is to provide an electric vehicle controller box, which solves the problem that dust easily accumulates in the ventilation slot during long-term use, resulting in reduced air circulation and reduced heat dissipation.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An electric vehicle controller box includes a box body, an air duct is provided in the shell wall of the box body, and an air intake cover is fixedly connected to one end of the box body, and the air intake cover is in communication with the air duct.
[0008] An air intake pipe is fixedly connected to the front of the air intake hood. A filter mechanism is provided on the air intake pipe. The filter mechanism includes a windproof cover. The windproof cover is fixedly connected to the end of the air intake pipe away from the air intake hood. A dustproof net is fixedly connected to the windproof cover.
[0009] Preferably, the windshield is trumpet-shaped and the dustproof net is hemispherical.
[0010] Preferably, a rotating rod is rotatably connected to the inner wall of the dustproof net, and a cleaning rod is fixedly connected to one end of the rotating rod located on the outer side of the dustproof net.
[0011] Preferably, the cleaning rod is vortex-shaped, and there is a gap between the cleaning rod and the dustproof net area, and the cleaning rod is provided with an air jet.
[0012] Preferably, the rotating rod is a hollow shaft, and the end of the cleaning rod located inside the windshield is fixedly connected to a windshield, and the windshield is in communication with the interior of the rotating rod.
[0013] Preferably, the rotating rod has a connecting hole at the position outside the dustproof net, and the interior of the rotating rod is connected to the air jet through the connecting hole.
[0014] Preferably, the windshield is hemispherical in shape, and the diameter of the windshield's air inlet end is smaller than the diameter of the windshield's air inlet end.
[0015] By employing the above technical solution, this utility model provides an electric vehicle controller box. It possesses at least the following beneficial effects:
[0016] I. This utility model increases the contact area between the box and the air by opening air ducts in the shell wall, thereby improving the heat dissipation effect. By connecting the air intake hood to the air intake pipe, airflow can be generated and poured into the air intake pipe during the operation of the electric vehicle. The entry of fresh air causes the air inside the air duct to be discharged, so that the heat generated inside the air duct can be quickly carried away by the air flow for heat dissipation. Furthermore, by setting the windproof cover on the air intake pipe in a funnel shape, the air intake of the air intake pipe can be increased, thereby increasing the air flow speed and improving the heat dissipation effect. The dustproof net set on the windproof cover can effectively filter impurities in the air, preventing the accumulation of dust in the air duct from reducing the airflow and thus reducing the heat dissipation effect. Moreover, the dustproof net has a hemispherical design, so when impurities come into contact with the surface of the dustproof net, they will usually slide off along the surface of the dustproof net.
[0017] II. In this utility model, when the airflow passes through the dustproof net and enters the windshield, a portion of the airflow will enter the windshield. Guided by the windshield, the airflow passes through the air inlet and the inside of the rotating rod, then enters the connecting hole, and is sprayed onto the surface of the dustproof net from the narrow air nozzle on the cleaning rod to clean it, so as to avoid impurities clogging the dustproof net. Since the cleaning rod is vortex-shaped, when the airflow is sprayed out from the air nozzle, it will also push the cleaning rod to rotate, so as to facilitate a thorough cleaning of the surface of the dustproof net.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] An electric vehicle controller box, such as Figure 1 - Figure 4 As shown, the device includes a box body 1, with an air duct 11 inside the shell wall of the box body 1. An air intake hood 2 is fixedly connected to one end of the box body 1, and the air intake hood 2 is connected to the air duct 11. An air intake pipe 3 is fixedly connected to the front of the air intake hood 2. A filter mechanism 4 is provided on the air intake pipe 3. The filter mechanism 4 includes a windproof hood 41, which is fixedly connected to the end of the air intake pipe 3 away from the air intake hood 2. A dustproof net 42 is fixedly connected to the windproof hood 41. The windproof hood 41 is trumpet-shaped, and the dustproof net 42 is hemispherical.
[0026] In this embodiment, by providing an air duct 11 on the shell wall of the box 1, the contact area between the box 1 and the air can be increased to improve the heat dissipation effect. By connecting the air intake cover 2 to the air intake pipe 3, air can be generated and flowed into the air intake pipe 3 during the operation of the electric vehicle. The entry of fresh air causes the air inside the air duct 11 to be discharged, so that the heat generated inside the air duct 11 can be quickly carried away by the air flow to facilitate heat dissipation. Furthermore, by setting the windshield 41 on the air intake pipe 3 in a trumpet shape, the air intake of the air intake pipe 3 can be increased to improve the air flow speed and enhance the heat dissipation effect. The dustproof net 42 provided on the windshield 41 can effectively filter impurities in the air, preventing the accumulation of dust in the air duct 11 from reducing the airflow of the air duct 11 and thus reducing the heat dissipation effect. Moreover, the dustproof net 42 is designed in a hemispherical shape, so when impurities come into contact with the surface of the dustproof net 42, they will usually slide off along the spherical surface of the dustproof net 42.
[0027] like Figure 2 , Figure 3 , Figure 4 As shown, preferably, a rotating rod 421 is rotatably connected to the inner wall of the dustproof net 42. A cleaning rod 422 is fixedly connected to one end of the rotating rod 421 on the outer side of the dustproof net 42. The cleaning rod 422 is vortex-shaped, and there is a gap between the cleaning rod 422 and the area of the dustproof net 42. An air jet 425 is provided on the cleaning rod 422. The rotating rod 421 is a hollow shaft. A wind shield 423 is fixedly connected to one end of the cleaning rod 422 on the inner side of the windproof cover 41. The wind shield 423 is connected to the interior of the rotating rod 421. A connecting hole 426 is provided on the outer side of the rotating rod 421. The interior of the rotating rod 421 is connected to the air jet 425 through the connecting hole 426. The wind shield 423 is hemispherical in shape, and the diameter of the air inlet end of the wind shield 423 is smaller than the diameter of the air inlet end of the windproof cover 41.
[0028] In this embodiment, when the airflow passes through the dustproof net 42 and enters the windshield 41, a portion of the airflow will enter the windshield 423. Guided by the windshield 423, the airflow passes through the air inlet 424 and through the inside of the rotating rod 421, then enters the connecting hole 426, and is sprayed onto the surface of the dustproof net 42 from the narrow air jet 425 on the cleaning rod 422 to clean it, so as to avoid impurities clogging the dustproof net 42. Since the cleaning rod 422 is vortex-shaped, when the airflow is sprayed out from the air jet 425, it will also push the cleaning rod 422 to rotate, so as to facilitate a thorough cleaning of the surface of the dustproof net 42.
[0029] This utility model discloses an electric vehicle controller box. In use, by creating an air duct 11 on the shell wall of the box 1, the contact area between the box 1 and the air is increased, thus improving heat dissipation. The air intake cover 2 connects to the air intake pipe 3, allowing airflow to enter the air intake pipe 3 during electric vehicle operation. The influx of fresh air causes the air inside the air duct 11 to be expelled, facilitating rapid heat dissipation by quickly removing heat generated inside the air duct 11. Furthermore, by designing the air intake pipe 3's windshield 41 in a trumpet shape, the air intake pipe 3's airflow speed is increased, improving heat dissipation. The dust filter 42 on the windshield 41 effectively filters impurities in the air, preventing dust accumulation in the air duct 11 and thus preventing heat loss. The reduced airflow of the dust filter 42 leads to a decrease in heat dissipation. Furthermore, the hemispherical design of the dust filter 42 means that impurities will slide off the spherical surface when they come into contact with it. When the airflow passes through the dust filter 42 and enters the windshield 41, some of the airflow will enter the windshield 423. Guided by the windshield 423, the airflow passes through the air inlet 424, passes through the inside of the rotating rod 421, and then enters the connecting hole 426. It is then sprayed onto the surface of the dust filter 42 from the narrow nozzle 425 on the cleaning rod 422 to clean it, thus preventing impurities from clogging the dust filter 42. Since the cleaning rod 422 is vortex-shaped, when the airflow is ejected from the nozzle 425, it will also push the cleaning rod 422 to rotate, which facilitates a thorough cleaning of the surface of the dust filter 42.
