Patent number: 10850687Abstract: In a vehicle-mounting structure disclosed by the present specification, a housing (20) of an electric power controller (5) is supported above an in-vehicle transaxle via a bracket having an insulative vibration-proof material. The housing (20) and the transaxle are connected to each other by power cables (19). A braided wire (17) for grounding is routed along the power cables (19). A connector (10) of the power cables (19) has a resin flange (112) on a surface thereof that is joined to the housing (20). The connector (10) is fixed to the housing (20) by bolts (12a and 13a) that penetrate the flange (112). An end fitting (16) of the braided wire (17) is attached to the flange (112). The end fitting (16) and the bolt (13a) are electrically connected to each other by a conductive plate (14a).Type: GrantFiled: July 11, 2018Date of Patent: December 1, 2020Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, SUMITOMO WIRING SYSTEMS, LTD.Inventors: Kenshi Yamanaka, Shinichi Miura, Keisuke Sawazaki, Yasuhiro Kudo, Kan Murai

Patent number: 10471842Abstract: An on-vehicle structure of a power converter includes a housing of the power converter mounted on a vehicle, a structure mounted on the vehicle, and a high-voltage connector attached to the housing. The high-voltage connector is configured to apply a voltage exceeding a predetermined threshold voltage, the high-voltage connector is positioned between the housing and the structure such that the high-voltage connector faces the structure in a removal direction of the high-voltage connector when the high-voltage connector is attached to the housing, and in a state where the high-voltage connector is attached to the housing, a length of a portion of the high-voltage connector embedded in the housing is determined so as to be longer than a distance between the high-voltage connector and the structure.Type: GrantFiled: September 24, 2018Date of Patent: November 12, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Keisuke Sawazaki, Kenshi Yamanaka, Hiromi Yamasaki, Hitoshi Imura, Akira Saito

Patent number: 10434884Abstract: A vehicle includes a motor housing accommodating motors for driving wheels, and a power control unit fixed on the motor housing. The power control unit includes: a stacked unit in which multiple power modules accommodating power semiconductor elements for electric power conversion and multiple coolers are stacked; and reactors. The stacked unit is disposed in the case of the power control unit such that the stacking direction of the power modules and the coolers is directed toward the vehicle-longitudinal direction. The reactors are disposed in the case so as not to overlap with the stacked unit as viewed from the stacking direction.Type: GrantFiled: March 29, 2018Date of Patent: October 8, 2019Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATIONInventors: Keisuke Sawazaki, Kenshi Yamanaka, Ryusuke Baba, Hiromi Yamasaki, Hitoshi Imura, Hideaki Tachibana
