[0057] An embodiment of the present application provides a vehicle 200 , which includes a suspension motor 110 and a cooling system 100 . The suspension motor 110 is used to adjust suspension parameters of the vehicle 200 , and the first cooling channel 31 of the cooling system 100 is used to transport cooling medium to the suspension motor 110 .

[0058] It is understandable that the suspension motor 110 generates a large amount of heat during operation, which increases the operating temperature of the suspension motor 110. For the suspension motor 110, excessively high temperature can easily cause the magnets inside the suspension motor 110 to demagnetize or the windings to burn out.

[0059] See also Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of a cooling structure of a vehicle 200 provided in one embodiment of the present application is shown; Figure 2 A schematic diagram of the cooling structure of a vehicle 200 provided in another embodiment of the present application is illustrated.

[0060] The embodiment of the present application provides a cooling system 100, such as Figure 1 and Figure 2 As shown, the cooling system 100 includes a control valve 20, a first cooling channel 31 and a first sensor 41. The control valve 20 includes a liquid inlet 21 and a first liquid outlet 22. The first cooling channel 31 is connected to the first liquid outlet 22. The first cooling channel 31 is used to transport cooling medium to the suspension motor 110 of the vehicle 200. The first sensor 41 is used to detect the temperature of the cooling medium flowing back from the suspension motor 110 to the control valve 20. The control valve 20 adjusts the size of the first liquid outlet 22 according to the detection data of the first sensor 41.

[0061] Specifically, in one embodiment, Figure 1 As shown, the suspension motor 110 includes a first heat dissipation pipeline 111 , the first cooling channel 31 is in communication with the first heat dissipation pipeline 111 of the suspension motor 110 , and the cooling medium flows through the first heat dissipation pipeline 111 to cool the suspension motor 110 .

[0062] In another embodiment, Figure 2 As shown, the first cooling channel 31 includes a first heat dissipation section 312 . The first heat dissipation section 312 is at least partially in contact with the suspension motor 110 to cool the suspension motor 110 .

[0063] The existing suspension motor is provided with a cooling system, and the heat generated by the suspension motor is difficult to dissipate, resulting in a high operating temperature, causing the magnet inside the suspension motor to lose magnetism and causing it to malfunction.

[0064] The cooling system 100 of the present application transports cooling medium to the suspension motor 110 of the vehicle 200 through the first cooling channel 31 to achieve long-term stable operation of the suspension motor 110; at the same time, the control valve 20 of the cooling system 100 of the present application adjusts the size of the first liquid outlet 22 based on the detection data of the first sensor 41, and then distributes the cooling medium flow rate, controls the cooling efficiency of the cooling system 100 on the suspension motor 110, and has higher energy utilization.

[0065] In one embodiment, the suspension motor 110 is a linear motor.

[0066] In one embodiment, the vehicle 200 includes a driving device 120 for driving the vehicle 200 to move, and the cooling system 100 includes a second cooling channel 32 for conveying a cooling medium to the driving device 120 .

[0067] As for the drive device 120, the drive device 120 of the electric vehicle includes a motor and a battery. Excessively high temperatures can easily cause the magnets inside the motor to demagnetize or the windings to burn out. Similarly, high temperatures can shorten the battery life and reduce the discharge capacity, and even cause the battery to explode. The drive device 120 of the fuel vehicle includes an engine. Excessively high temperatures will reduce the lubrication performance of the lubricants inside the engine and accelerate the wear of its components. The high-temperature working environment will also reduce the engine's air intake, causing the engine's power to decrease.

[0068] See also Figure 3 A schematic diagram of the cooling structure of a vehicle 200 provided in another embodiment of the present application is shown.

[0069] In one embodiment, if Figure 3 As shown, the cooling system 100 includes a second cooling channel 32 and a second sensor 42, and the control valve 20 includes a second liquid outlet 23. The second cooling channel 32 is connected to the second liquid outlet 23 and is used to transport cooling medium to the drive device 120 of the vehicle 200. The second sensor 42 is used to detect the temperature of the cooling medium flowing back from the drive device 120 to the control valve 20. The control valve 20 adjusts the size of the second liquid outlet 23 according to the detection data of the second sensor 42.

[0070] exist Figure 3 In the cooling structure of the provided vehicle 200, the cooling system 100 includes a power pump 10, a control valve 20, a first cooling channel 31, and a second cooling channel 32. The power pump 10 is used to pressurize the cooling medium. The control valve 20 includes a liquid inlet 21, a first liquid outlet 22, and a second liquid outlet 23. The liquid inlet 21 is connected to the power pump 10. The first cooling channel 31 is connected to the first liquid outlet 22 and is used to supply the cooling medium to the suspension motor 110 of the vehicle 200. The second cooling channel 32 is connected to the second liquid outlet 23 and is used to supply the cooling medium to the drive device 120 of the vehicle 200.

[0071] As will be understood, the power pump 10 pressurizes the cooling medium to force it to flow to the control valve 20. The control valve 20 then divides the cooling medium into a first cooling channel 31 and a second cooling channel 32, which are used to deliver the cooling medium to the suspension motor 110 and the drive device 120, respectively. The suspension motor 110 is provided with a first cooling channel 111, which is connected to the first cooling channel 31. The cooling medium flows into the first cooling channel 31 through the first cooling channel 31 to reduce the temperature of the suspension motor 110. The drive device 120 is provided with a second cooling channel 121, which is connected to the second cooling channel 32. The cooling medium flows into the second cooling channel 32 through the second cooling channel 32 to reduce the temperature of the drive device 120. After passing through the suspension motor 110 or the drive device 120, the cooling medium returns to the control valve 20, causing the cooling medium to circulate within the cooling system 100 to cool the suspension motor 110 and the drive device 120.

[0072] exist Figure 3 The cooling structure of the provided vehicle 200 further includes a first sensor 41 and a second sensor 42. The first sensor 41 is used to detect the temperature of the cooling medium flowing back from the suspension motor 110 to the control valve 20, and the second sensor 42 is used to detect the temperature of the cooling medium flowing back from the drive device 120 to the control valve 20. The control valve 20 adjusts the size of the first liquid outlet 22 and / or the second liquid outlet 23 based on the detection data of the first sensor 41 and / or the second sensor 42.

[0073] The first sensor 41 and the second sensor 42 are respectively disposed on the pipeline that flows back from the suspension motor 110 to the control valve 20 and the pipeline that flows back from the drive device 120 to the control valve 20. After the cooling medium flows out of the first heat dissipation pipeline 111 or the second heat dissipation pipeline 121, it is detected by the first sensor 41 or the second sensor 42. The detected temperature data is transmitted to the control valve 20. Based on the detection data from the first sensor 41 and the second sensor 42, the control valve 20 changes the size of the first liquid outlet 22 and the second liquid outlet 23 to adjust the flow rate of the cooling medium flowing through the first heat dissipation pipeline 111 and the second heat dissipation pipeline 121, thereby controlling the cooling efficiency of the suspension motor 110 and the drive device 120.

[0074] It can be understood that the cooling system 100 is provided with a circulating cooling medium, which passes through the first cooling channel 31 and the second cooling channel 32 respectively to cool the suspension motor 110 and the drive device 120, so that the suspension motor 110 and the drive device 120 are at a suitable operating temperature, avoiding high temperature damage to the suspension motor 110 or the drive device 120, improving the reliability of the suspension motor 110 and the drive device 120, and extending their service life.

[0075] It can be understood that cooling pipes are respectively provided for the suspension motor 110 and the drive device 120, and the two cooling pipes are independent of each other. More space is required in the vehicle 200 to arrange the two independent cooling pipes, and more energy is required for the two cooling pipes to work.

[0076] Figure 3 In the cooling structure of the provided vehicle 200, the first sensor 41 and the second sensor 42 are used to detect the temperature of the returning cooling medium to obtain the cooling efficiency required by the suspension motor 110 and the drive device 120. The size of the first liquid outlet 22 and the second liquid outlet 23 are adjusted by the control valve 20 to distribute the flow of the first cooling channel 31 and the second cooling channel 32, thereby controlling the cooling effect of the suspension motor 110 and the drive device 120 to improve energy utilization.

[0077] It can be understood that in some embodiments, the cooling efficiencies required by the suspension motor 110 and the drive device 120 are generally different. In other embodiments, the cooling efficiencies required by the suspension motor 110 and the drive device 120 are inversely proportional. For example, in one embodiment, the vehicle 200 generally travels at a low speed when passing through a road section with poor road conditions. At this time, the suspension motor 110 works at a larger load and requires a smaller cooling efficiency. The drive device 120 works at a smaller load and requires a smaller cooling efficiency.

[0078] In another embodiment, vehicle 200 can travel at low or high speeds while passing through a road section with good road conditions. During this time, the load on suspension motor 110 is relatively small, requiring less cooling efficiency. The remaining cooling efficiency can be used to support drive unit 120 operating under a higher load. Therefore, the cooling medium temperature detected by first sensor 41 and second sensor 42 can be used to distribute the cooling efficiency of cooling system 100, thereby improving energy utilization.

[0079] It should be pointed out that the cooling system 100 of the present application can not only be used for cooling the vehicle's suspension motor 110 and drive device 120 in the vehicle 200, but also cooling channels and sensors for cooling other components can be added to the cooling system 100 to further improve energy utilization. The specific positions of the cooling channels and sensors can be specifically set based on the components that need to be cooled.
