Publication number: 20220324313Abstract: A total of four anchor points (5fl, 5fr, 5rl, and 5rr) are provided at front positions and rear positions of a left side member and a right side member (31 and 3r) provided on a floor (2). A drive motor (9), an inverter (10), and a transaxle (11), which serve as a drive unit (8), are mounted on the rear suspension cross member (4) supportively suspended from the respective anchor points. A junction box (21), a charger (22), and a DC-AC inverter (23), which serve as a power supply unit (20), are attached to the upper side of the floor (2). The junction box (21) relays electric power to supply it to the inverter (10). On the upper surface of the floor (2), an upper front floor cross member (16) is provided between the anchor points at the front position, and an upper rear floor cross member (17) is provided between the anchor points at the rear position. The power supply unit (20) is disposed between the members (16, 17).Type: ApplicationFiled: November 9, 2020Publication date: October 13, 2022Applicant: MITSUBISHI JIDOSHA KOGYO KABUSHIKI KAISHAInventor: Shoji TANIZAWA
