Patent number: 11591025Abstract: A front vehicle-body structure controls inward breakage of an apron reinforcement in the event of a small overlap collision, without increasing weight. Embodiments include a pair of right and left apron reinforcements extending in a vehicle front-rear direction; and a pair of right and left hinge pillars respectively connected to rear ends of the pair of apron reinforcements. A reinforcement outer member of the apron reinforcement includes a linear portion extending in the vehicle front-rear direction from a rear end of the apron reinforcement connected to the hinge pillar to an intermediate portion of the apron reinforcement. A horizontal bead, provided as a deformation facilitating portion to facilitate deformation toward an inside of a vehicle body, is disposed on an outer surface portion positioned on a vehicle-width-direction outer side of the linear portion, the horizontal bead having a reduced longitudinal rigidity toward a front side in the vehicle front-rear direction.Type: GrantFiled: July 19, 2021Date of Patent: February 28, 2023Assignee: MAZDA MOTOR CORPORATIONInventors: Yasushi Ishikawa, Yuichi Morita, Yusuke Desaki, Yusuke Matsumura, Ken Fujimoto, Yusaku Yamaguchi

Publication number: 20220388573Abstract: A rigid suspension tower structure includes a sus-tower for supporting a damper, and a bracket for mounting a component to be secured to the sus-tower. The sus-tower includes a curved side wall portion joined to a front side frame of a vehicle body and extending upward, and a top portion supporting the upper end of the damper. The side wall portion has a pair of mounting portions made of bulging portions. The mounting portions are formed on mutually different sides in a vehicle front-rear direction with a virtual line interposed therebetween, the line being formed by intersecting the side wall portion and a plane that extends parallel to a vehicle width direction and passes through the central axis of the damper. The bracket straddles the line and is secured to the mounting portions.Type: ApplicationFiled: May 6, 2022Publication date: December 8, 2022Applicant: MAZDA MOTOR CORPORATIONInventors: Takashi NARAHARA, Yusuke DESAKI

Patent number: 11420682Abstract: In a vehicle having a large side door opening, a vehicle-body structure suppresses, during a collision in which an apron reinforcement recedes, bending deformation of a hinge pillar at a mounting portion of the apron reinforcement. Embodiments include a reinforcement member inside a closed cross-section of a hinge pillar overlapping a mounting portion of an apron reinforcement in the up-down direction. The reinforcement member includes a body extending in the up-down direction spaced apart from the hinge pillar, a front flange portion at a front portion of the body, a lateral flange portion at a rear portion of the body, a front ridge portion between the body and the front flange portion, and a rear ridge portion between the body and the lateral flange portion. Each of the front ridge portion and the rear ridge portion is continuously provided over the reinforcement member in the vehicle up-down direction.Type: GrantFiled: November 4, 2020Date of Patent: August 23, 2022Assignee: MAZDA MOTOR CORPORATIONInventors: Shuji Muraoka, Yusuke Desaki, Tsuneaki Zenitani, Satoshi Nakamura
