Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0040] The present application embodiment provides an electric vehicle. Figure 1 For electric vehicles, a controller 12 is generally provided. Depending on the type of electric vehicle, the specific functions that the controller 12 can cover are also different. The controller 12 is mainly used to collect various control signals and operation data of the electric vehicle, and issue control instructions after processing to control the operation of the electric vehicle.

[0041] It should be noted that in the embodiment of the present application, the controller 12 can select any existing controller as needed. For example, the controller 12 can select an existing controller such as a vehicle controller, a central processing unit, an electronic controller unit (ECU), an intelligent driving controller, etc. Of course, other conventional controllers can also be selected as needed. This embodiment of the present application is not limited to this.

[0042] It should be noted that the electric vehicle in this application may refer to a large vehicle, a small vehicle, a special-purpose vehicle, etc. For example, according to the vehicle model, the electric vehicle in this application may be a sedan model, an off-road vehicle model, a multi-purpose vehicle (MPV) model or other models.

[0043] In addition, the power source of electric vehicles is generally electric drive, which is powered by power batteries. Power batteries can receive and store electrical energy. Electric drive is a combination of electric motors and transmission parts, which is used to convert the power of the power battery into driving kinetic energy and transmit it to the wheels of the vehicle, thereby driving the electric vehicle.

[0044] According to different driving modes of the electric drive, the electric drive can be divided into a front electric drive 13 and a rear electric drive 14. Among them, the kinetic energy only drives a pair of front wheels as the front electric drive 13, which has the characteristics of light weight and easy acceleration. The kinetic energy only drives a pair of rear wheels as the rear electric drive 14, which has the characteristics of stable driving and relatively comfortable. Of course, the electric vehicle can also be provided with a front electric drive 13 and a rear electric drive 14 at the same time as needed to obtain better power output and acceleration performance. For the convenience of description, the electric vehicle provided in the embodiment of the present application is described by taking the simultaneous provision of a front electric drive 13 and a rear electric drive 14 as an example.

[0045] In order to facilitate the heat dissipation of the controller 12 and the electric drive, the controller 12 is provided with a controller water inlet pipe 1201 and a controller water outlet pipe 1202, and the coolant flows into the controller water inlet pipe 1201 and flows out from the controller water outlet pipe 1202 to achieve the heat dissipation of the controller 12. The front electric drive 13 is provided with a front electric drive water inlet pipe 1301 and a front electric drive water outlet pipe (not shown in the figure), and the coolant flows into the front electric drive water inlet pipe 1301 and flows out from the front electric drive water outlet pipe to achieve the heat dissipation of the front electric drive 13. The rear electric drive 14 is provided with a rear electric drive water inlet pipe and a rear electric drive water outlet pipe (not shown in the figure), and the coolant flows into the rear electric drive water inlet pipe and flows out from the rear electric drive water outlet pipe to achieve the heat dissipation of the rear electric drive 14.

[0046] The electric vehicle provided in the embodiment of the present application includes a thermal management system in addition to the controller 12 and the electric drive. Since the output power of the front electric drive 13 is much greater than that of the controller 12, the heat dissipation demand of the front electric drive 13 is relatively large. However, the front electric drive 13 is far away from the radiator 1. The embodiment of the present application can make the coolant quickly enter the front electric drive 13 through the thermal management system, and increase the coolant flow rate to meet the heat dissipation demand of the front electric drive 13, thereby improving the overall heat dissipation effect of the electric vehicle.

[0047] Specifically, refer to Figure 1 and Figure 4 The thermal management system mainly includes a radiator 1, a three-way joint 2, a first pipeline 3, a second pipeline 4, a third pipeline 5 and a fourth pipeline 6. The three-way joint 2 includes an input joint 201, a first output joint 202 and a second output joint 203 that are connected. The input joint 201 is connected to the water outlet of the radiator 1 through the first pipeline 3, the first output joint 202 is connected to the controller water inlet pipe 1201 through the second pipeline 4, and the second output joint 203 is connected to the front electric drive water inlet pipe 1301 through the third pipeline 5. The fourth pipeline 6 is connected to the controller water outlet pipe 1202 and the front electric drive water inlet pipe 1301 respectively.

[0048] The electric vehicle provided in the embodiment of the present application utilizes the first pipeline 3 to connect the water outlet of the radiator 1 and the input connector 201 of the three-way connector 2, so as to introduce the coolant in the radiator 1 into the three-way connector 2, and then input the coolant into the controller water inlet pipe 1201 through the first output connector 202 and the second pipeline 4 to cool the controller 12, and input the coolant into the front electric drive water inlet pipe 1301 through the second output connector 203 and the third pipeline 5 to cool the front electric drive 13. At the same time, the coolant in the controller water outlet pipe 1202 is also input into the front electric drive water inlet pipe 1301 through the fourth pipeline 6, forming a parallel structure, which enables the coolant to quickly cool the front electric drive 13 to meet the heat dissipation requirements of the front electric drive 13, thereby improving the heat dissipation effect and heat dissipation efficiency of the electric vehicle.

[0049] On this basis, refer to Figure 1 The embodiment of the present application also provides a thermal management system, which mainly includes a radiator 1, a three-way joint 2, a first pipeline 3, a second pipeline 4, a third pipeline 5 and a fourth pipeline 6.

[0050] Specifically, refer to Figure 4 The three-way connector 2 includes an input connector 201, a first output connector 202, and a second output connector 203 that are connected to each other. The input connector 201 is connected to the water outlet of the radiator 1 through a first pipeline 3. The first output connector 202 is connected to the controller water inlet pipe 1201 through a second pipeline 4. The second output connector 203 is connected to the front electric drive water inlet pipe 1301 through a third pipeline 5. The fourth pipeline 6 is respectively connected to the controller water outlet pipe 1202 and the front electric drive water inlet pipe 1301.

[0051] The thermal management system provided in the embodiment of the present application utilizes the first pipeline 3 to connect the water outlet of the radiator 1 and the input connector 201 of the three-way connector 2, so as to introduce the coolant in the radiator 1 into the three-way connector 2, and then input the coolant into the controller water inlet pipe 1201 through the first output connector 202 and the second pipeline 4 to cool the controller 12, and input the coolant into the front electric drive water inlet pipe 1301 through the second output connector 203 and the third pipeline 5 to cool the front electric drive 13. At the same time, the coolant in the controller water outlet pipe 1202 is also input into the front electric drive water inlet pipe 1301 through the fourth pipeline 6, forming a parallel structure, which enables the coolant to quickly cool the front electric drive 13 to meet the heat dissipation requirements of the front electric drive 13, thereby improving the heat dissipation effect and heat dissipation efficiency.

[0052] In some embodiments of the present application, reference Figure 4 The second output connector 203 is provided with a one-way throttle valve 7, which is used to adjust the output flow of the second output connector 203 and limit the reflux of the coolant. The throttle valve 701 and the one-way valve 702 are connected in parallel to form the one-way throttle valve 7. The one-way throttle valve 7 has the functions of the one-way valve 702 and the throttle valve 701.

[0053] By setting the one-way throttle valve 7, on the one hand, the one-way conduction characteristic of the one-way valve 702 can be used to prevent the coolant at the front electric drive 13 from flowing back to the three-way joint 2, so that the coolant can flow smoothly throughout the vehicle. On the other hand, the flow rate adjustment characteristic of the throttle valve 701 can be used to adjust the flow rate of the coolant entering the controller 12 and the front electric drive 13, so as to timely adjust the pressure of the coolant under different working conditions to avoid overheating damage due to too low pressure or internal impact on electrical components caused by too high pressure.

[0054] Further, in some embodiments of the present application, the one-way throttle valve 7 mainly includes: a throttle valve 701 and a one-way valve 702. The throttle valve 701 is arranged at one end where the second output connector 203 is connected to the input connector 201. The radius of the throttle valve 701 is smaller than the inner diameter of the second output connector 203, and is used to adjust the flow of the coolant entering the controller 12 and the front electric drive 13. The one-way valve 702 is arranged at the outlet of the throttle valve 701, and the coolant can flow out from the second output connector 203 after passing through the throttle valve 701 from the input connector 201, but cannot flow from the second output connector 203 to the input connector 201, thereby preventing backflow.

[0055] Furthermore, in some embodiments of the present application, the one-way valve 702 mainly includes: a sphere 7021 and a stopper 7022. The radius of the sphere 7021 is greater than the radius of the throttle valve 701. The stopper 7022 is arranged on a side of the sphere 7021 away from the throttle valve 701, and is used to limit the range of motion of the sphere 7021. The stopper 7022 can be a stopper rod, which is arranged along the radial direction of the one-way valve 702 and can abut against the sphere 7021.

[0056] The ball 7021 can be used to make the coolant flow from the input connector 201 to the second output connector 203 in one direction to prevent backflow. The limiter 7022 is used to limit the range of movement of the ball 7021. After the ball 7021 is taken out by the coolant at the outlet of the throttle valve 701, the limiter 7022 intercepts the ball 7021. The inner wall of the one-way valve 702 can also be provided with a rubber pad, which is used to seal the ball 7021 on the one hand and reduce the wear of the ball 7021 on the other hand.

[0057] After the coolant from the input connector 201 enters the throttle valve 701, if the coolant pressure is too low, the ball 7021 closes the outlet of the throttle valve 701, and most of the coolant passes through the first output connector 202 and the second pipeline 4 and first enters the controller 12, and then enters the front electric drive 13 through the fourth pipeline 6. If the coolant pressure is too high, the ball 7021 opens the outlet of the throttle valve 701, and the coolant can directly enter the front electric drive 13 through the third pipeline 5.

[0058] Furthermore, in some embodiments of the present application, the radius R2 of the throttle valve 701 is 0.3R1 to 0.4R1, wherein R1 is the inner diameter of the second output connector 203, and the radius R3 of the sphere 7021 is 1.4R2 to 1.6R2.

[0059] In some embodiments of the present application, reference Figure 2 and Figure 3, the third pipeline 5 is connected to the fourth pipeline 6 through the adapter 8. The adapter 8 is used to facilitate the connection of the third pipeline 5, the fourth pipeline 6 and the front electric drive water inlet pipe 1301, and can also save the length of the fourth pipeline 6, thereby reducing the use cost.

[0060] It should be noted that in the embodiment of the present application, the structure of the adapter 8 is not limited, and any existing structure can be selected as needed, for example, a quick-insert three-way connector can be selected.

[0061] It should be noted that the embodiment of the present application does not restrict the connection between the above-mentioned pipelines and the three-way connector 2, the controller 12 and the front electric drive 13. A snap-on connection structure can be used for easy installation, or a fastened connection structure can be used for stable connection.

[0062] In some embodiments of the present application, reference Figure 3 , the input connector 201 is interference-connected with the first pipeline 3 to improve the connection stability between the input connector 201 and the first pipeline 3. The second pipeline 4 is connected to the first output connector 202 and the controller water inlet pipe 1201 respectively through the clamp 9. The third pipeline 5 is connected to the second output connector 203 and the front electric drive water inlet pipe 1301 respectively through the clamp 9. The fourth pipeline 6 is connected to the controller water outlet pipe 1202 and the front electric drive water inlet pipe 1301 respectively through the clamp 9. The clamp 9 is elastic, easy to install, and has low cost.

[0063] Further, in some embodiments of the present application, referring to Figure 2 The first pipeline 3 , the second pipeline 4 , the third pipeline 5 and the fourth pipeline 6 can all be fixed on the vehicle body by a bracket 15 to improve the installation stability of the first pipeline 3 , the second pipeline 4 , the third pipeline 5 and the fourth pipeline 6 .

[0064] Taking the installation of the first pipeline 3 as an example, the bracket 15 is provided with a mounting hole and a tube. The inner diameter of the tube is slightly larger than the outer diameter of the first pipeline 3, so that the first pipeline 3 can be inserted into the tube. The bracket 15 is fixed to the vehicle body by passing the mounting hole of the bracket 15 through a fastener. The fastener can be a conventional fastener such as a screw or a bolt, and correspondingly, the mounting hole can be a threaded hole or a round hole.

[0065] It should be noted that in the embodiment of the present application, the materials of the first pipeline 3, the second pipeline 4, the third pipeline 5 and the fourth pipeline 6 are not limited, and any existing structure can be selected as needed, for example, a nylon tube can be selected. In addition, the bracket 15 is not limited, for example, the bracket 15 can be a sheet metal bracket, etc.

[0066] In some embodiments of the present application, reference Figure 1The thermal management system further includes a fifth pipeline 10. The fifth pipeline 10 is connected to the first pipeline 3 and the rear electric drive water inlet pipe of the electric vehicle respectively. By connecting the first pipeline 3 and the rear electric drive water inlet pipe through the fifth pipeline 10, the coolant of the radiator 1 can be used to dissipate heat for the rear electric drive 14 at the same time.

[0067] In some embodiments of the present application, reference Figure 1 The thermal management system further includes a sixth pipe 11. The sixth pipe 11 is connected to the rear electric drive water outlet pipe and the front electric drive water outlet pipe of the electric vehicle respectively. One end of the sixth pipe 11 is connected to the rear electric drive water outlet pipe and the front electric drive water outlet pipe, and the other end is connected to other heat-generating components 16, so that the coolant used by the front electric drive 13 and the rear electric drive 14 can be further transferred to other heat-generating components 16 of the electric vehicle, so as to further improve the heat dissipation effect of the electric vehicle.

[0068] It should be noted that in the embodiment of the present application, the materials of the fifth pipeline 10 and the sixth pipeline 11 are not limited, and any existing structure can be selected as needed.
