As the core hub of the vehicle, the vehicle controller plays an irreplaceable key role in ensuring stable vehicle operation and efficient control. However, with the explosive growth in the number of electronic devices in the vehicle and the continuous increase in functional complexity, the problem of electromagnetic interference between electronic components has become increasingly prominent, becoming a major bottleneck restricting the performance improvement and functional optimization of the vehicle controller.

[0003] Existing vehicle controllers integrate a large number of different types of electronic components. During operation, these components generate electromagnetic signals of a certain intensity, which in turn generate electromagnetic interference of varying degrees, thus affecting the use of the vehicle controller. Therefore, a vehicle controller based on the YunTu platform is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle controller based on the YunTu platform to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle controller based on the YunTu platform, including a connecting plate, a controller housing on the top of the connecting plate, a circuit board connected to the top inner side of the controller housing by screws, and a shielding component on the top of the controller housing;

[0006] The shielding assembly includes a top cover, a motor housing at the bottom center of the top cover, a cooling fan at the motor output end inside the motor housing, a connecting box at the bottom of the top cover, a filter screen at the bottom of the connecting box, a partition at the bottom of the filter screen, and a shielding plate between the partitions.

[0007] In a preferred embodiment, ventilation openings are provided on both sides of the inside of the controller housing and on the top of the top cover. The partition is mesh-like, and the controller housing and the top cover are in communication with the partition.

[0008] In a preferred embodiment, the circuit board has buffer pads around its top perimeter and the bottom of the partition. The bottom of the connecting box is connected to the circuit board via the buffer pads. The shielding plate is made of copper-silver alloy and is folded. The shielding plate is located on the outside of each electronic component.

[0009] In a preferred embodiment, a spring pad is provided at one end of the interior of the controller housing, a retaining plate is provided on one side of the spring pad, one side of the retaining plate is connected to one side of the connector box and the circuit board, a junction box is provided on the top side of the circuit board, and the other end of the controller housing is connected to the junction box through an opening groove.

[0010] In a preferred embodiment, the controller housing has ventilation slots on both sides, and one end of the ventilation slots is connected to the vehicle's ventilation pipe.

[0011] In a preferred embodiment, both the top of the controller housing and the top cover are provided with threaded grooves, and the inside of the threaded grooves is provided with fixing bolts. The controller housing and the top cover are connected by fixing bolts, and the top of the circuit board is equipped with YunTu YTM32B1 series chips and electronic components.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a folded shielding plate made of copper-silver alloy, which possesses excellent conductivity and electromagnetic shielding performance. The high conductivity of copper-silver alloy enhances its ability to reflect and absorb electromagnetic signals, making it more effective at blocking the propagation of electromagnetic interference between electronic components compared to ordinary shielding materials. The folded design further increases the shielding area, providing comprehensive electromagnetic shielding for sensitive components such as the YunTu YTM32B1 series chips. Simultaneously, the folded copper-silver alloy shielding plate can quickly absorb the heat dissipated by electronic components and the YunTu YTM32B1 series chips, improving the controller's heat dissipation efficiency.

[0014] This invention utilizes a motor-driven cooling fan within the shielding assembly to rapidly draw in air, accelerating airflow within the controller. During vehicle operation, ventilation openings on both sides of the controller housing and the top of the cover, along with the mesh partitions on both sides of the shielding plate, create a smooth airflow channel. External cool air enters through the ventilation openings on the top of the cover, flows through the shielding plate and circuit board to remove heat, and then exits through the ventilation openings on both sides of the controller housing. This ensures that the YunTu YTM32B1 series chips and all electronic components remain at a suitable operating temperature. The filter at the bottom of the connector effectively filters the incoming air, preventing dust and impurities from entering the controller. Attached Figure Description

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3 This utility model provides a vehicle controller based on the YunTu platform, including a connecting plate 1, a controller housing 2 on the top of the connecting plate 1, a circuit board 3 connected to the top inner side of the controller housing 2 by screws, and a shielding component 4 on the top of the controller housing 2.

[0022] The shielding assembly 4 includes a top cover 401, a motor housing 402 located at the bottom center of the top cover 401, a cooling fan 403 located at the motor output end inside the motor housing 402, a connecting box 404 located at the bottom of the top cover 401, a filter screen 405 located at the bottom of the connecting box 404, a partition 406 located at the bottom of the filter screen 405, and a shielding plate 407 located between the partitions 406.

[0023] By actively operating the cooling fan 403 inside the shielding assembly 4 under the drive of the motor, air can be quickly drawn in, accelerating the air circulation inside the controller. At the same time, the folded copper-silver alloy shielding plate 407 can quickly absorb the heat emitted by the electronic components 6 and the YunTu YTM32B1 series chip 5. When the vehicle is running, a smooth air convection channel is constructed through the ventilation openings 13 on both sides inside the controller housing 2 and the top of the top cover 401, as well as the mesh partitions 406 on both sides of the shielding plate 407. External cold air can enter from the ventilation opening 13 on the top of the top cover 401, flow through the shielding plate 407 and the circuit board 3 to remove heat, and then be discharged from the ventilation openings 13 on both sides inside the controller housing 2, ensuring that the YunTu YTM32B1 series chip 5 and all electronic components 6 are always at a suitable operating temperature.

[0024] Ventilation openings 13 are provided on both sides of the inside of the controller housing 2 and on the top of the top cover 401. The partition 406 is mesh, and the controller housing 2, the top cover 401 and the partition 406 are interconnected.

[0025] The top and four sides of the circuit board 3 and the bottom of the partition 406 are provided with buffer pads 7. The bottom of the connecting box 404 is connected to the circuit board 3 through the buffer pads 7. The shielding plate 407 is made of copper-silver alloy and is folded. The shielding plate 407 is located on the outside of each electronic component 6. By using the folded shielding plate 407 made of copper-silver alloy, it has excellent conductivity and electromagnetic shielding performance. The high conductivity of copper-silver alloy makes it more effective in reflecting and absorbing electromagnetic signals. Compared with ordinary shielding materials, it can more effectively block the propagation of electromagnetic interference generated between electronic components 6. The folded design further increases the shielding area. The electronic components 6 include power management chips, communication chips, sensor interface chips, driver chips, memory chips, and crystal oscillators.

[0026] A spring pad 10 is provided at one end of the interior of the controller housing 2. A retaining plate 11 is provided on one side of the spring pad 10. One side of the retaining plate 11 is connected to one side of the connector box 404 and the circuit board 3. A junction box 12 is provided on one side of the top of the circuit board 3. The other end of the controller housing 2 is connected to the junction box 12 through a groove. The buffer pads provided around the top of the circuit board and the bottom of the partition can effectively buffer the impact force caused by road bumps and vibrations during vehicle operation. The buffer pads can prevent the circuit board from directly colliding with components such as the connector box and partition, and prevent the solder joints of electronic components from loosening or the circuit from breaking due to vibration. The spring pad and the retaining plate at one end of the interior of the controller housing cooperate with each other to firmly fix the connector box and the circuit board. The spring pad can absorb part of the impact force through its own elastic deformation when the vehicle vibrates or is impacted, while the retaining plate restricts the displacement of the connector box and the circuit board, further enhancing the stability of the overall structure.

[0027] The controller housing 2 has ventilation slots 8 on both sides, and one end of the ventilation slots 8 is connected to the car's ventilation pipe.

[0028] Both the top of the controller housing 2 and the top cover 401 are provided with threaded grooves 9, and the inside of the threaded grooves 9 is provided with fixing bolts. The controller housing 2 and the top cover 401 are connected by fixing bolts. The top of the circuit board 3 is connected to the YunTu YTM32B1 series chip 5 and electronic components 6 through circuit connection.

[0029] The working principle and usage process of this utility model are as follows: First, the cooling fan 403 inside the shielding component 4 is driven by a motor to operate actively, which can quickly draw in air and accelerate the air circulation inside the controller. At the same time, the folded copper-silver alloy shielding plate 407 can quickly absorb the heat emitted by the electronic components 6 and the YunTu YTM32B1 series chip 5. Then, when the vehicle is running, the ventilation openings 13 on both sides of the controller housing 2 and the top of the top cover 401, as well as the mesh partitions 406 on both sides of the shielding plate 407, form a smooth air convection channel. External cold air can enter from the ventilation opening 13 on the top of the top cover 401, flow through the shielding plate 407 and the circuit board 3 to remove heat, and then be discharged from the ventilation openings 13 on both sides of the controller housing 2. Finally, the folded shielding plate 407 made of copper-silver alloy has excellent conductivity and electromagnetic shielding performance. The high conductivity of copper-silver alloy makes it more effective in reflecting and absorbing electromagnetic signals. Compared with ordinary shielding materials, it can more effectively block the propagation of electromagnetic interference generated between electronic components 6.
