[0031] 1 to 7 , in some embodiments, the present application provides a water channel connection structure 100, which includes a motor controller 10, a motor 20, and a connection pipe 30. The motor controller 10, the motor 20, and the connection pipe 30 work in coordination to ensure the performance and safety of the vehicle under various driving conditions.

[0032] The motor controller 10 plays a variety of key roles in electric vehicles or hybrid vehicles, such as converting electric energy, regulating the operation of the motor 20, protecting system safety, and realizing energy recovery. The motor 20 is a core component of the vehicle drive system, which converts electric energy into mechanical energy and provides the power required for the vehicle to travel. The connecting pipe 30 is connected between the motor controller 10 and the motor 20, so that the coolant is transported from the motor controller 10 to the motor 20 through the connecting pipe 30 to reduce the temperature of the motor 20 and the motor controller 10 and prevent the motor 20 and the motor controller 10 from overheating.

[0033] Specifically, the motor controller 10 is provided with a water outlet 11 on the side facing the motor 20, and the water outlet 11 is provided with a first assembly hole 111, and the motor 20 is provided with a water inlet 21 on the side facing the motor controller 10, and the water inlet 21 is provided with a second assembly hole 211. The coolant passing through the motor controller 10 is discharged through the water outlet 11 and continues to flow to the water inlet 21 of the motor 20, so as to achieve effective cooling of the motor 20 and the motor controller 10, which helps to keep the operating temperature of the motor controller 10 and the motor 20 within a safe range, avoid the performance degradation or damage of the motor 20 and the motor controller 10 due to overheating, and improve the overall efficiency and reliability of the system.

[0034] The setting of the first assembly hole 111 facilitates the connection between the connecting tube 30 and the motor controller 10, so that the coolant can enter the connecting tube 30. The setting of the second assembly hole 211 facilitates the connection between the connecting tube 30 and the motor 20, so that the coolant in the connecting tube 30 can enter the motor 20, thereby ensuring a good connection between the motor controller 10, the motor 20 and the connecting tube 30, and further ensuring a good flow of the coolant, thereby improving the stability and reliability of cooling.

[0035] Furthermore, the connecting tube 30 axially includes a first guide portion 31, a tube body 32 and a second guide portion 33 which are connected in sequence. The diameter of the first guide portion 31 is smaller than the diameter of the first assembly hole 111, so that the first guide portion 31 can guide the tube body 32 to enter the first assembly hole 111. The diameter of the second guide portion 33 is smaller than the diameter of the second assembly hole 211, so that the second guide portion 33 can guide the tube body 32 to enter the second assembly hole 211.

[0036] By respectively providing a first guide portion 31 and a second guide portion 33 at both ends of the connecting pipe 30, and by making the diameter of the first guide portion 31 smaller than the diameter of the first assembly hole 111, and the diameter of the second guide portion 33 smaller than the diameter of the second assembly hole 211, during assembly, the pipe body 32 of the connecting pipe 30 can be first stably installed in the first assembly hole 111 of the motor controller 10 under the guidance of the first guide portion 31, and then the motor controller 10 with the connecting pipe 30 can be stably installed in the second assembly hole 211 of the motor 20 under the guidance of the second guide portion 33, so that under the coordinated guidance of the first guide portion 31 and the second guide portion 33, fast and simple docking is achieved, and there is no need to precisely align and adjust the water outlet pipe of the motor controller 10 and the water inlet nozzle of the motor 20, which simplifies the assembly process between the motor 20 and the motor controller 10, reduces the difficulty of assembly, and helps to improve the connection stability and reliability between the motor 20 and the motor controller 10. At the same time, the first guide portion 31 and the side wall of the first assembly hole 111 are spaced apart, and the second guide portion 33 and the side wall of the second assembly hole 211 are spaced apart, which helps to reduce damage to the side wall of the first assembly hole 111 caused by the first guide portion 31 during assembly and damage to the side wall of the second assembly hole 211 caused by the second guide portion 33 during assembly.

[0037] In a feasible embodiment, the side walls of the tube body 32 and the first assembly hole 111 are spaced apart, and the side walls of the tube body 32 and the second assembly hole 211 are spaced apart, that is, there is a gap between the connecting tube 30 and the first assembly hole 111 and between the connecting tube 30 and the second assembly hole 211, so that when the tube body 32 is respectively assembled to the motor controller 10 and the motor 20 through the first guide portion 31 and the second guide portion 33, the tube body 32 is prevented from damaging the side walls of the first assembly hole 111 and the second assembly hole 211.

[0038] Optionally, the diameter of the tube body 32 is smaller than the diameter of the first guide portion 31 and the second guide portion 33. By reducing the diameter of the tube body 32, it is helpful to increase the flow rate of the coolant and reduce the flow resistance. At the same time, the diameters of the first guide portion 31 and the second guide portion 33 are relatively large to increase the contact area between the connecting tube 30 and the side wall of the first assembly hole 111 and the side wall of the connecting tube 30 and the second assembly hole 211, which helps to improve the connection stability between the connecting tube 30 and the motor controller 10 and the connecting tube 30 and the motor 20, and further helps to ensure that the tube body 32 can be aligned when entering the first assembly hole 111 and the second assembly hole 211, thereby improving the assembly accuracy and reducing the assembly error.

[0039] In a feasible embodiment, the diameter of at least part of the first guide portion 31 gradually decreases in a direction away from the second guide portion 33, and the diameter of at least the second guide portion 33 gradually decreases in a direction away from the first guide portion 31, that is, at least part of the first guide portion 31 and at least part of the second guide portion 33 form a cone. The cone-shaped first guide portion 31 and the second guide portion 33 enable the connecting tube 30 to be automatically centered during assembly, thereby reducing the difficulty of alignment during assembly, facilitating the connecting tube 30 to accurately enter the first assembly hole 111 and the second assembly hole 211, thereby improving the accuracy and efficiency of assembly, and optimizing the assembly process between the connecting tube 30 and the motor controller 10 and the connecting tube 30 and the motor 20.

[0040] In a feasible embodiment, at least part of the first guide portion 31 forms a first inclination angle, at least part of the second guide portion 33 forms a second inclination angle, and the first inclination angle is smaller than the second inclination angle. It should be noted that the first inclination angle in the present application is the inclination angle on the outer peripheral surface of the conical first guide portion 31, and the second inclination angle is the inclination angle on the outer peripheral surface of the conical second guide portion 33.

[0041] Generally, when assembling the connecting tube 30, the first guide portion 31 of the connecting tube 30 is first connected to the first assembly hole 111 of the motor controller 10. Therefore, the smaller first inclination angle can provide guidance for the installation of the first guide portion 31 during assembly, and helps to reduce the stress during assembly of the connecting tube 30 and the motor controller 10, and ensure the connection stability between the first guide portion 31 and the first assembly hole 111. Then, the motor controller 10 and the motor 20 equipped with the connecting tube 30 are assembled. At this time, the larger second inclination angle facilitates guiding the second guide portion 33 of the connecting tube 30 into the second assembly hole 211, reduces the assembly error, and helps to provide a larger range of assembly guidance for the second guide portion 33 and the second assembly hole 211, so that the second guide portion 33 and the second assembly hole 211 can be automatically guided during the assembly process, making the entire assembly process smooth and efficient.

[0042] In some embodiments, in order to ensure the sealing between the connecting pipe 30 and the first assembly hole 111 and between the connecting pipe 30 and the second assembly hole 211 to avoid leakage of the coolant, the water channel connection structure 100 also includes at least a first seal 41 and a second seal 42. The first seal 41 is arranged between the connecting pipe 30 and the first assembly hole 111 to achieve sealing between the connecting pipe 30 and the motor controller 10, and the second seal 42 is arranged between the connecting pipe 30 and the second assembly hole 211 to achieve sealing between the connecting pipe 30 and the motor 20.

[0043] Specifically, at least a first sealing groove 311 and a second sealing groove 331 are provided on the connecting pipe 30. The first sealing groove 311 is provided on the first guide portion 31. The first sealing groove 311 is used to install the first sealing member 41, so that the first sealing member 41 can seal between the connecting pipe 30 and the first assembly hole 111. The second sealing groove 331 is located on the second guide portion 33. The second sealing groove 331 is used to install the second sealing member 42. The second sealing member 42 can seal between the connecting pipe 30 and the second assembly hole 211, so as to prevent the coolant from leaking from the gap between the connecting pipe 30 and the first assembly hole 111 and the gap between the connecting pipe 30 and the second assembly hole 211. Optionally, the first sealing member 41 and the second sealing member 42 are both O-rings.

[0044] It can be understood that the number of sealing grooves and the number of sealing elements are consistent and the present application does not limit the specific number and specific setting positions of the sealing grooves and sealing elements, which can be set according to the actual sealing effect.

[0045] Optionally, the first seal 41 and the second seal 42 are both made of elastic materials. By setting the elastic first seal 41 and the second seal 42, when the connecting pipe 30 and the first assembly hole 111 and the connecting pipe 30 and the second assembly hole 211 are assembled, the elastic first seal 41 can enter the first assembly hole 111 through elastic deformation, and fill the gap between the connecting pipe 30 and the side wall of the first assembly hole 111 through elastic deformation, and the elastic second seal 42 can enter the second assembly hole 211 through elastic deformation, and fill the gap between the connecting pipe 30 and the second assembly hole 211 through elastic deformation, providing a reliable sealing effect, preventing the leakage of the coolant, and improving the stability and reliability of the water channel connection structure 100. At the same time, the elastically arranged first seal 41 and the second seal 42 cooperate with the conical first guide part 31 and the second guide part 33 to avoid the connecting pipe 30 from damaging the side walls of the first assembly hole 111 and the second assembly hole 211 during installation, thereby improving the quality of assembly. Furthermore, the elastically arranged first seal 41 and second seal 42 can absorb and buffer vibration, reduce looseness between the connecting pipe 30 and the motor controller 10 and between the connecting pipe 30 and the motor 20 caused by vibration, and improve the stability of the vehicle.

[0046] Furthermore, a first seal 41 is installed on the first guide portion 31, and a second seal 42 is installed on the second guide portion 33, which can not only ensure the effectiveness of the connection seal, but also help to reduce the processing accuracy requirements of the motor 20 and the motor controller 10 during processing, thereby reducing production costs.

[0047] In an optional embodiment, chamfers are further provided on the side walls at the openings of the first assembly hole 111 and the second assembly hole 211, so that the first guide portion 31 can smoothly enter the first assembly hole 111 and the second guide portion 33 can smoothly enter the second assembly hole 211 through the chamfers and the cooperation of the conical first guide portion 31 and the second guide portion 33, thereby reducing the possibility of the first guide portion 31 and the second guide portion 33 damaging the side walls of the first assembly hole 111 and the second assembly hole 211.

[0048] In a feasible embodiment, the water outlet 11 of the motor controller 10 and the water inlet 21 of the motor 20 are arranged at intervals. The gap between the water outlet 11 and the water inlet 21 can ensure that the connection has sufficient flexibility, thereby increasing the coaxiality tolerance during connection.

[0049] In an optional embodiment, the water inlet 21 of the motor 20 is further provided with a third sealing groove 212, which is arranged around the first assembly hole 111, and the waterway connection structure 100 further includes a third sealing member 43, which is installed in the third sealing groove 212, and the third sealing member 43 is used for sealing between the water outlet 11 of the motor controller 10 and the water inlet 21 of the motor 20. The third sealing member 43 can further seal the joint surface between the motor controller 10 and the motor 20, thereby improving the sealing effect and thus improving the reliability of the waterway connection structure 100.

[0050] In other embodiments not shown in the figure, the water outlet 11 of the motor controller 10 is also provided with a fourth sealing groove, and the fourth sealing groove is arranged around the second assembly hole 211. The water channel connection structure 100 also includes a third sealing member 43, and the third sealing member 43 is installed in the fourth sealing groove. The third sealing member 43 is used for sealing between the water outlet 11 of the motor controller 10 and the water inlet 21 of the motor 20.

[0051] In other feasible embodiments, the water inlet 21 of the motor 20 is further provided with a third sealing groove 212, and the third sealing groove 212 is arranged around the first assembly hole 111. The water outlet 11 of the motor controller 10 is further provided with a fourth sealing groove, and the fourth sealing groove is arranged around the second assembly hole 211. The third sealing member 43 is installed in the third sealing groove 212 and the fourth sealing groove, thereby achieving sealing between the water outlet 11 of the motor controller 10 and the water inlet 21 of the motor 20.

[0052] It should be noted that the motor controller 10 in the present application can be a single motor controller 10, and accordingly, the motor 20 is a single motor 20; or, the motor controller 10 can also be a dual motor controller 10, and accordingly, the motor 20 is a dual motor 20. In this case, two water channel connection structures 100 are configured, and the two water channel connection structures 100 are respectively used to connect a motor controller 10 and a motor 20. At this time, the setting of the first guide portion 31 and the second guide portion 33 can effectively reduce the assembly difficulty caused by the assembly error between the two first assembly holes 111 and the second assembly hole 211, and improve the convenience of assembly, that is, the water channel connection structure 100 in the present application can be applicable to electric drive systems with multiple sealed connections.

[0053] As the same concept, the present application provides a vehicle on the other hand, the vehicle includes a water channel connection structure 100, and the water channel connection structure 100 is the water channel connection structure 100 in the above embodiment.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
