Problems solved by technology

The casing of the existing high-power electronic water pump is made of aluminum alloy. Its complex volute design will bring problems such as complex molds, time-consuming finishing, and aluminum alloy air shrinkage holes. Induction heating and other complex processes (with time-consuming, deformation impact and other defects)
[0003] When the existing aluminum alloy housing is assembled with the motor stator, an induction heating assembly process is required, which takes time for assembly, high machining costs, waste of materials, and environmental pollution at the same time

Abstract

The invention relates to an automotive electronic water pump. The automotive electronic water pump comprises a pump case, a motor which is connected with the pump case through a bearing, and a motor shell which is arranged on the motor and connected with the pump case. The pump case and the motor shell are made of plastics. Due to the fact that the pump case and the motor shell which are made of the light plastics are used for replacing a pump case and a motor shell which are made of aluminum alloy, the purpose of relieving weight burdens of automobiles so as to reduce oil consumption can be achieved. The assembling procedures of the automotive electronic water pump are simplified so that the lower assembly cost and quality failure risks can be realized.

Description

technical field [0001] The invention relates to an automobile electronic water pump. Background technique [0002] Automotive electronic water pumps are currently being widely used in all types of vehicles, including passenger cars and commercial vehicles, traditional internal combustion engine vehicles, hybrid vehicles, and pure electric vehicles; for pure electric vehicles, due to the increase in battery density and other reasons, it is necessary to use The electronic water pump will also step up to the 200W power range. The casing of the existing high-power electronic water pump is made of aluminum alloy. Its complex volute design will bring problems such as complex molds, time-consuming finishing, and aluminum alloy air shrinkage holes. Complicated processes such as induction heating (with defects such as time-consuming, deformation and impact). [0003] When the existing aluminum alloy housing is assembled with the motor stator, an induction heating assembly process i...
