Description

Technical Field

[0001] This utility model relates to the field of controller technology, and in particular to a controller for electric vehicles. Background Technology

[0002] The electric vehicle controller is a crucial component used to control the starting, running, forward and reverse movement, speed, and stopping of the electric vehicle motor. The harsh and complex operating conditions of electric vehicles pose significant challenges to traditional electric vehicle controller technology. Heat dissipation is essential for ensuring the controller's lifespan and safe controllability. In particular, as a core component of electric vehicles, the controller is becoming increasingly smaller, and its heat dissipation requirements are becoming more stringent. The controller's heat dissipation efficiency directly determines the control safety, lifespan, and reliability of the electric vehicle.

[0003] The applicant discovered through a search that a Chinese patent, "A Novel Controller for Electric Vehicles," with publication number "CN218163403U," discloses a controller body comprising a protective box and a controller body. The protective box has a built-in protective cavity, within which a protective plate is slidably mounted. A damping component and a shock-absorbing spring are disposed between the bottom end of the protective plate and the bottom end of the protective cavity. The controller body is mounted on the top of the protective plate. A water-cooling device is disposed within the protective cavity. The water-cooling device includes a heat sink, a heat sink plate, a positioning plate, bolts, and a water pump. Water-cooling cavities are respectively disposed on the left and right sides of the protective plate, and fixing grooves are respectively disposed on the left and right sides of the top of the protective plate. Through the water-cooling device, the operator controls the water pump to operate, thereby circulating the coolant in the jacket through the heat sink plate, heat sink plate, and heat pipes, thus exchanging heat between the coolant and the controller body, thereby improving the water-cooling effect of the controller body.

[0004] However, in high-temperature environments, the electronic components of existing controllers may experience performance drift, leading to decreased control accuracy, difficulty in starting the vehicle, unstable power output, and shortened driving range. Utility Model Content

[0005] The purpose of this invention is to provide a controller for electric vehicles to solve the problem mentioned in the background art where the radiator causes a decrease in vehicle performance due to high temperature.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a controller for electric vehicles, including a control box, a switch door provided on one side of the control box surface, and control components fixedly connected inside the control box. An exhaust structure is provided on one side of the control box surface to guide the heat flow inside the control box outward. A cleaning structure is provided on the top surface of the inner wall of the control box to wipe away the dust accumulated on one side of the inner wall of the control box, thereby ensuring heat dissipation.

[0007] Preferably, the exhaust structure includes an exhaust vent, a baffle, and an exhaust fan. The exhaust vent is fixedly located on one side of the control box surface, and the baffle is fixedly connected to the opposite sides of the inner wall of the exhaust vent. The opposite sides of the inner wall are jointly fixedly connected to the baffle.

[0008] Preferably, the exhaust structure further includes an exhaust fan, which is fixedly connected to one side of the inner wall of the exhaust port and faces outward.

[0009] Preferably, the clearing structure includes a transmission rod and a transmission gear. The transmission rod is fixedly and rotatably connected to one side of the bottom surface of the inner wall of the control box, and the transmission gear is fixedly connected to one side of the transmission rod wall.

[0010] Preferably, the cleaning structure further includes a transmission toothed plate and a toothed groove. The transmission toothed plate is disposed on one side of the transmission gear, and the toothed groove is fixedly connected to one side of the surface of the transmission toothed plate and meshes with the transmission gear.

[0011] Preferably, the cleaning structure further includes a fixing port and a cleaning block. The two fixing ports are opened on both sides of the control box surface, and the cleaning block is fixedly connected to one side of the transmission gear plate surface, and the cleaning block is in a fitted state with one side of the grid surface.

[0012] Preferably, the clearing structure further includes a fixing frame and a drive motor. The fixing frame is fixedly connected to one side of the top surface of the control box, and the drive motor is fixedly connected to the bottom surface of the inner wall of the fixing frame. The output end of the drive motor passes through the interior of the fixing frame and is fixedly connected to the top surface of the drive rod.

[0013] Preferably, a plurality of air inlet grilles are provided on one side of the surface of the control box, a limit block is fixedly connected to the bottom surface of the transmission gear plate, and the bottom surface of the limit block is slidably connected to the bottom surface of the control box.

[0014] The technical effects and advantages of this utility model are as follows: This utility model uses an exhaust fan to allow air from the outside of the control box to enter, carrying the hot air generated by the control components. The hot air is then discharged from the control box through the baffle. When the exhaust fan operates for a long time, dust will accumulate on one side of the inner baffle surface. At this time, simply drive the transmission motor to rotate the transmission rod, causing the transmission rod to rotate the transmission gear on one side of the rod wall. This causes the transmission gear to drive the transmission tooth plate to slide laterally on one side of the baffle surface, thereby using a cleaning block to clean the inner side of the baffle. This allows the device to clean even during long-term operation, ensuring continuous heat dissipation and stable performance of the control components. Attached Figure Description

A ventilation structure 4 is provided on one side of the surface of the control box 1, which can guide the heat flow inside the control box 1 to the outside. A cleaning structure 7 is provided on the top surface of the inner wall of the control box 1, which can wipe away the dust accumulated on one side of the inner wall of the control box 1, thereby ensuring the heat dissipation effect.

[0023] The technical effects achieved by the above embodiments are as follows: This utility model uses an exhaust fan 403 to allow air from the outside of the control box 1 to enter, driving the hot air generated by the control component 3, and then allowing the hot air to be discharged from the control box 1 through the baffle 402. When the exhaust fan 403 works for a long time, dust will accumulate on one side of the surface of the inner baffle 402. At this time, it is only necessary to drive the transmission motor 708 to drive the transmission rod 701 to rotate, so that the transmission rod 701 drives the transmission gear 702 on one side of the rod wall to rotate, thereby causing the transmission gear 702 to drive the transmission tooth plate 703 to slide laterally on one side of the surface of the baffle 402. Thus, the cleaning block 706 can clean the inner side of the baffle 402, so that the device can produce a cleaning effect during long-term operation, and the heat dissipation effect of the device can continue, thereby stabilizing the performance of the control component 3.

[0025] like Figure 2 and Figure 4 As shown, a controller for an electric vehicle includes all the contents of Embodiment 1. In addition, the exhaust structure 4 includes an exhaust port 401, a baffle 402, and an exhaust fan 403. The exhaust port 401 is fixedly opened on one side of the surface of the control box 1.

The exhaust structure 4 also includes an exhaust fan 403, which is fixedly connected to one side of the inner wall of the exhaust port 401 and faces outward.

[0026] The technical effect achieved by the above embodiment is as follows: the exhaust fan 403 allows air from the outside of the control box 1 to enter, which in turn drives the hot air generated by the control component 3, and then the hot air is discharged from the inside of the control box 1 through the baffle 402.

[0028] like Figures 2 to 4As shown, a controller for an electric vehicle includes all the contents of Embodiment 2. Furthermore, the clearing structure 7 includes a transmission rod 701 and a transmission gear 702. The transmission rod 701 is fixedly and rotatably connected to one side of the bottom surface of the inner wall of the control box 1. The transmission gear 702 is fixedly connected to one side of the rod wall of the transmission rod 701. The clearing structure 7 also includes a transmission gear plate 703 and a tooth groove 704. The transmission gear plate 703 is disposed on one side of the transmission gear 702, and the tooth groove 704 is fixedly connected to one side of the surface of the transmission gear plate 703, and the tooth groove 704 meshes with the transmission gear 702. The clearing structure 7 also includes... The cleaning structure 7 includes a fixing port 705 and a cleaning block 706. The two fixing ports 705 are located on both sides of the surface of the control box 1. The cleaning block 706 is fixedly connected to one side of the surface of the transmission tooth plate 703, and the cleaning block 706 is in a close fit with one side of the surface of the grid 402.

The output end of the transmission motor 708 passes through the interior of the fixing frame 707 and is fixedly connected to the top surface of the transmission rod 701.

[0029] The technical effect achieved by the above embodiment is as follows: However, when the exhaust fan 403 is working for a long time, a certain amount of dust will accumulate on one side of the surface of the internal baffle 402, thereby blocking the baffle 402 and affecting the heat dissipation effect. At this time, it is only necessary to make the transmission motor 708 drive the transmission rod 701 to rotate, so that the transmission rod 701 drives the transmission gear 702 on one side of the rod wall to rotate, thereby causing the transmission gear 702 to drive the transmission tooth plate 703 to slide laterally on one side of the surface of the baffle 402. While sliding, the transmission tooth plate 703 will also extend to a certain extent inside the fixing port 705. Finally, the cleaning block 706 is used to clean the baffle 402 on one side of the interior.
