Patent number: 11691494Abstract: A battery unit which stores plural battery modules therein is attached to respective lower faces of a pair of floor frames at its both sides. The battery unit comprises an attaching bracket which protrudes substantially horizontally from the battery case and is positioned just below the lower face of the floor frame with a distance therebetween. A specified rigidity ratio is set for an attachment portion of the battery unit to the floor frame, and the attaching bracket is attached to the lower face of the floor frame via an intermediate part such that the above-described rigidity ratio is 0.1 or greater.Type: GrantFiled: May 20, 2021Date of Patent: July 4, 2023Assignee: MAZDA MOTOR CORPORATIONInventors: Morihide Yamada, Kazuhisa Hatano, Hisashi Akune, Munenari Takahashi

Patent number: 11312220Abstract: There are provided a floor panel, a pair of right-and-left floor frames, and a battery unit supporting a battery module and mounted at the floor frames. The battery unit comprises the battery module, a pair of right-and-left side frames mounted at the pair of floor frames, and a pair of front-and-rear module supporting mechanisms which comprises a pair of front-and-rear cross frames respectively extending in a vehicle width direction and interconnecting the pair of side frames and mounting brackets supporting a front end portion and a rear end portion of the battery module. Bending rigidity, in a vertical direction, of the module supporting mechanism comprising the third cross frame and the first mounting bracket is set to be lower than that of the side frame.Type: GrantFiled: March 13, 2020Date of Patent: April 26, 2022Assignee: MAZDA MOTOR CORPORATIONInventors: Morihide Yamada, Kazuhisa Hatano, Hisashi Akune, Munenari Takahashi

Patent number: 9884649Abstract: A single cross member extending in a vehicle width direction is provided between a portion of a side sill which is positioned near a center pillar and a tunnel portion. A pair of seat-rail mounting seats are provided at a lower portion of the tunnel portion to be spaced apart from the cross member in a vehicle longitudinal direction. A seat rail is rigidly connected to the pair of seat-rail mounting seats at its bottom face. Thereby, the lightweight, high rigidity, and quietness of the vehicle can be attained.Type: GrantFiled: November 25, 2015Date of Patent: February 6, 2018Assignee: MAZDA MOTOR CORPORATIONInventors: Kouichi Nakaya, Munenari Takahashi, Masaki Mori
