Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a structure of an electronic water pump with a volute integrated on a valve plate. Background Art

[0002] New energy vehicles are currently the general trend in the automotive industry. The automotive drive system requires a more precise thermal management module to ensure that each energy-consuming component is at its optimal operating temperature. Most new energy vehicles are equipped with a thermal management integrated module, and an electronic water pump is installed in the thermal management integrated module. For example, a high-integration and high-reliability thermal management module structure proposed in the prior art publication number CN115303020A includes a manifold assembly; the manifold assembly includes a flow channel main board, a flow channel back board, and a water tank, and the flow channel back board, the flow channel main board, and the water tank are integrally welded in sequence; the water outlet of the water tank is communicated with the flow channels in the flow channel back board and the flow channel main board in sequence; electronic water pumps are provided at the flow channel outlets on the flow channel main board. However, there are many parts in the coolant system, the assembly process is complex, and it occupies a large amount of space in the vehicle, which in turn leads to a high manufacturing cost of the vehicle. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model provides a structure of an electronic water pump with a volute integrated on a valve plate, which integrates the volute onto the valve plate, reduces the separate parts of the electronic water pump, reduces the cost, and optimizes the process route of the electronic water pump production line.

[0004] A structure of an electronic water pump with a volute integrated on a valve plate according to the utility model includes an electronic water pump and a volute integrated valve plate. A volute flow channel surface is provided on the volute integrated valve plate. The installation of the electronic water pump can be completed by installing the electronic water pump without a volute at the volute flow channel surface on the volute integrated valve plate; during production, a volute flow channel surface consistent with the original volute of the electronic water pump is designed on the installation surface of the volute integrated valve plate, so that the volute can be eliminated as an external cooperation part during the development of the electronic water pump. During the production in an automated factory, since the electronic water pump has no volute, the incoming inspection cost and the assembly process cost can be reduced, and the cost of separate parts can be reduced.

[0005] Preferably, a plurality of mounting holes are axially provided on the end surface of the volute integrated valve plate with respect to the volute flow channel surface; during installation, the electronic water pump without a volute is aligned with the mounting holes to perform the installation action, which is convenient for assembly.

[0006] Preferably, a plurality of valve plate flow channels are provided at one end of the volute integrated valve plate away from the electronic water pump, and the valve plate flow channels are internally communicated with the volute flow channel surface; integrating the volute onto the volute integrated valve plate can completely unify the water pump flow channel and the valve plate flow channel.

[0007] Preferably, the volute integrated valve plate is obtained by integral injection molding to form a valve plate with a volute flow channel surface. The valve plate flow channel at the lower part of the volute integrated valve plate is formed simultaneously with the volute integrated valve plate by injection molding. Injection molding is beneficial for processing and improving the installation accuracy.

[0008] Compared with the prior art, the beneficial effects of the present utility model are as follows: During production, a volute flow channel surface consistent with the original volute of the electronic water pump is designed on the installation surface of the electronic water pump for the volute integrated valve plate. This enables the elimination of the volute as an outsourced part during the development of the electronic water pump. In an automated factory production, since the electronic water pump does not have a volute, the incoming inspection cost and the assembly process cost can be reduced, and the cost of sub-components can be decreased.
