Title: Water pump
Inventor: PARK JONG WON
IPC: F04D29/22
Filed: 2020-08-26
Abstract: The present invention relates to an electric water pump and, more specifically, to an electric water pump capable of enabling bolt-free assembly by ultrasonically fusing a housing and a cover of the electric water pump. In accordance with the present invention, the electric water pump includes: a housing; a rotor and a stator mounted in the housing; an impeller mounted to be rotatable by the rotor; and a cover combined with an upper part of the housing so as to surround the impeller. The cover has a first protrusion protruding in an axial direction from a lower side coming in contact with an upper side of an upper part of the housing toward the upper side of the housing, and a second protrusion protruding in a centrifugal direction from an inner side coming in contact with a lateral side of the upper part of the housing toward the lateral side of the housing. The housing has a first groove formed on the upper side to be engaged with the first protrusion, and a second groove formed on the lateral side to be engaged with the second protrusion. The protrusions are fused and combined with the grooves through ultrasonic waves. In accordance with the present invention, the protrusions of the cover and the grooves of the housing are engaged with each other to be fused and combined through ultrasonic waves. In this case, bolt-free assembly can be possible, which can lead to a reduction in the number of components. Thus, production costs can be saved. Moreover, in accordance with the present invention, the first protrusion protruding in an axial direction from the lower side of the cover is fused to be combined with the housing in the axial direction, and the second protrusion protruding in a centrifugal direction from the inner side of the cover is fused to be combined with the housing in the radial direction. In this case, since the water pump can be fused and combined in two directions: an axial direction and a radial direction, a bonding force and watertightness can be increased.
