In addition, the terms "first", "second", etc. in the application embodiments are only for the convenience of description, and cannot be understood as indicating or implying relative importance.

[0024] With the continuous development of technology, new energy vehicles are gradually popularized. The controller is an important part of the new energy vehicle, which can control the motor to work. At present, the existing controller is connected with the vehicle body by a hard connection, which increases the vibration of the controller with the vehicle, reduces the service life of the controller. The application provides a controller and a vehicle to solve the related technical problems.

[0025] As shown in Figure 1 The application provides a controller applied to a vehicle, which includes a shell 10, a circuit board 20 and a damping piece 30. The shell 10 includes a first shell 11 and a second shell 12. The first shell 11 and the second shell 12 are assembled to form a receiving space 100. The circuit board 20 is arranged in the receiving space 100. The two ends of the damping piece 30 are connected with the circuit board 20 and the second shell 12 respectively. The second shell 12 is used to be connected with the vehicle body of the vehicle.

[0026] By connecting the two ends of the damping piece 30 with the second shell 12 and the circuit board 20 respectively, the vibration of the vehicle body is absorbed, the impact on the circuit board 20 is reduced, the influence of vibration on the circuit board 20 is reduced, the loss of the circuit board 20 due to vibration is avoided, and the service life of the controller is improved.

[0027] Please refer to Figure 2 The first shell 11 is provided with a first air cooling channel 111. The first air cooling channel 111 is communicated with the receiving space 100, which can transfer the heat of the receiving space 100 to the outside through air flow, improve the heat dissipation capacity of the controller, and further improve the service life of the controller.

[0028] The first shell 11 is provided with a heat dissipation surface 112 on the side away from the receiving space 100. The heat dissipation surface 112 is provided with a heat dissipation groove 113. Compared with a plane, the heat dissipation groove 113 can increase the contact area of the first shell 11 and the external air, improve the heat exchange rate of the first shell 11 and the external air, further improve the heat dissipation capacity of the controller, and improve the service life of the controller. In other embodiments, the specific structure of the heat dissipation surface 112 is not limited.

[0029] The heat dissipation groove 113 extends from one side to the other side of the heat dissipation surface 112. This arrangement lengthens the heat dissipation groove 113, further increases the contact area between the first shell 11 and the external air, and improves the heat exchange rate between the controller and the external environment, thereby improving the heat dissipation effect of the controller and prolonging the service life of the controller. In other embodiments, the specific structure of the heat dissipation groove 113 is not limited.

[0030] The heat dissipation groove 113 is arranged in multiple numbers and is arranged at intervals. By arranging multiple heat dissipation grooves 113, the contact area between the first shell 11 and the external air is increased, the heat exchange rate between the controller and the external environment is improved, and the heat dissipation effect of the controller is improved and the service life of the controller is prolonged. In other embodiments, the specific number of heat dissipation grooves 113 is not limited.

[0031] Please refer to Figure 3 As shown, the second shell 12 includes a top surface 121, a bottom surface 122, and a pair of side surfaces 123. The top surface 121 faces the first shell 11. The bottom surface 122 faces away from the first shell 11. The pair of side surfaces 123 connects the top surface 121 and the bottom surface 122 and is arranged opposite to each other.

[0032] The second shell 12 is provided with a liquid cooling channel 124. By arranging the liquid cooling channel 124, the controller can use the cooling liquid to dissipate heat from the second shell 12, further enhancing the heat dissipation capacity of the controller, reducing the probability of damage to the controller due to high temperature, and prolonging the service life of the controller.

[0033] The liquid cooling channel 124 extends in a serpentine shape. This arrangement lengthens the contact length of the liquid cooling channel 124 and the second shell 12, increases the heat exchange area of the cooling liquid and the second shell 12, further improves the heat dissipation effect of the controller, and further prolongs the service life of the controller. In other embodiments, the specific structure of the liquid cooling channel 124 is not limited.

[0034] The second shell 12 is provided with a second air cooling channel 125, and the first air cooling channel 111 communicates the accommodation space 100 and the second air cooling channel 125. The heat generated by the circuit board 20 during operation will be transferred to the accommodation space 100, and the heat generated by the accommodation space 100 can be transferred to the first air cooling channel 111 and the second air cooling channel 125. The first shell 11 and the second shell 12 can both provide air cooling, improving the heat dissipation effect of the controller and prolonging the service life of the controller.

[0035] Please refer to Figure 4As shown, the liquid cooling channel 124 includes an inlet 1241 and an outlet 1242. The inlet 1241 is arranged on one of the pair of sides 123, and the outlet 1242 is arranged on the other of the pair of sides 123, so that the liquid cooling channel 124 is arranged through the second housing 12.

[0036] By arranging the inlet 1241 and the outlet 1242 on the opposite pair of sides 123, the length of the liquid cooling channel 124 is extended, the heat exchange area between the cooling liquid and the second housing 12 is further increased, the heat dissipation capacity of the controller is enhanced, and the service life of the controller is prolonged. In other embodiments, the specific structural form of the inlet 1241 and the outlet 1242 is not limited.

[0037] As shown, Figure 1 The damping member 30 can include a column 31 and a spring 32. The spring 32 is sleeved in the column 31. The two ends of the spring 32 are connected to the second housing 12 and the circuit board 20, respectively. The spring 32 itself has good vibration isolation performance, which improves the protection effect of the controller on the circuit board 20. At the same time, the spring 32 has high stability and is convenient to maintain and replace.

[0038] The column 31 can be a hollow sleeve structure of rubber, which can further improve the vibration isolation effect of the damping member 30. In other embodiments, the specific structural form of the damping member 30 is not limited.

[0039] The application also provides a vehicle including a vehicle body and the above-mentioned controller. The second housing 12 is fixedly connected to the vehicle body. Specifically, the second housing 12 can be connected to the vehicle body longitudinal beam. Since the controller of the application is not easy to be damaged, the safety performance of the vehicle is improved. The vehicle of the application can be an electric vehicle, a hybrid vehicle, etc., and the specific type is not limited.
