Document Type and Number:
WIPO Patent Application WO/2024/060503
Kind Code:
A1
Abstract:
An oil pumping device and a vehicle. The oil pumping device (100) comprises: a motor structure (110), the motor structure comprising a drive shaft (1101), and the drive shaft (1101) rotating about an axis extending in the axial direction; a pump structure (103), comprising a pump housing (1032) and a pump rotor disposed on the pump housing (1032). The pump housing (1032) comprises: a pump body (105) and a pump cover (104) disposed at one axial end of the pump body (105), a receiving part being disposed between the pump body (105) and the pump cover (104), and the pump rotor being located in the receiving part. The pump rotor specifically comprises a first rotor part (106) and a second rotor structure (108) engaged with one another. The drive shaft (1101) and the first rotor part (106) are integrally formed. In the oil pumping device (100), the first rotor part (106) adopts an integrated structure, the drive shaft (1101), which rotates together with the motor rotor (1102), and the first rotor part (106), which cooperates with the second rotor structure (108), are integrally formed and manufactured, and the first rotor part (106) is supported by the housing and the pump body, so that the number of parts can be reduced and the assembly process is reduced, while the overall axial dimension can also be compressed.
