Publication number: 20190016283Abstract: Provided is a vehicle body structure capable of preventing separation between a bumper beam and a bumper beam mounting member on the non-collision side at the time of an offset collision. The vehicle body structure includes a bumper beam, a pair of bumper beam mounting members, and a pair of holding members. The holding member includes an outer mounting portion for mounting an outer side in the vehicle width direction of the holding member on the bumper beam mounting member, and a front mounting portion for mounting an inner side in the vehicle width direction of the holding member on the front surface portion of the bumper beam. The front mounting portion extends to a position corresponding to a vehicle width direction inner end portion of the bumper beam mounting member in a front-rear direction at least on the front surface portion of the bumper beam.Type: ApplicationFiled: July 9, 2018Publication date: January 17, 2019Inventors: Momoka FUJII, Tomohito KAMADA, Isamu NAKANISHI

Patent number: 10118647Abstract: A vehicle body structure having an increased capability to absorb impact in a front end of a tunnel member. The vehicle body structure includes a dash lower panel, a dash cross member and the tunnel member. The dash cross member has a convex shape with a central portion located forward of both ends in the vehicle width direction in plan view. The tunnel member has a tunnel closed cross-sectional portion constituting a part of the central portion of the dash cross member, a front fragile portion provided forward of the tunnel closed cross-sectional portion, and a rear tunnel member provided rearward of the tunnel closed cross-sectional portion. The front fragile portion has a lower compressive strength than that of the rear tunnel member, against a load from the front.Type: GrantFiled: March 11, 2016Date of Patent: November 6, 2018Assignee: HONDA MOTOR CO., LTD.Inventors: Masayasu Yoshida, Tomohito Kamada, Kiyohiko Matsuoka

Patent number: 9963170Abstract: A vehicle front structure includes a front side frame and a first load transmitting member that is joined to a front end and an outer surface in a vehicle-width direction of the front side frame and that tapers from the front of the vehicle toward the rear so as to be formed substantially in the shape of a triangle when viewed in plan view. The first load transmitting member includes a substantially U-shaped portion that is open toward the front side frame. A longitudinal-plate-like second load transmitting member is joined to and along the bottom of the substantially U-shaped portion. A closed cross section is formed by the bottom of the first load transmitting member and the second load transmitting member in a continuous manner in the longitudinal direction of the vehicle.Type: GrantFiled: March 25, 2016Date of Patent: May 8, 2018Assignee: HONDA MOTOR CO., LTD.Inventors: Akira Haga, Tomohito Kamada, Takehiro Kondo

Patent number: 9764772Abstract: A pair of left and right upper members are provided to extend substantially along a vehicle longitudinal direction on both sides of the left and right front side frames in a vehicle width direction and to have their rear ends joined to front pillars disposed at lateral ends of a cabin. Each of the upper members has a substantially rectangular shape in cross section constituted by left and right walls and upper and lower walls. A weak portion, such as a recess, is provided in at least one corner portion having no flange among corner portions formed between adjacent walls of the upper members.Type: GrantFiled: February 12, 2016Date of Patent: September 19, 2017Assignee: HONDA MOTOR CO., LTD.Inventors: Takehiro Kondo, Tomohito Kamada, Kiyohiko Matsuoka, Akira Haga

Patent number: 9630656Abstract: A vehicle body structure includes a dash lower panel including a wheel-arch-shaped portion that constitutes a portion of a wheel arch and separating a power unit chamber from a vehicle interior, a reinforcing panel covering the wheel-arch-shaped portion from a side of the vehicle interior, and a side sill extending in a front-rear direction and having a front end portion connected to an end portion in a vehicle width direction of the dash lower panel. The reinforcing panel includes a horizontal closed cross-section defining portion that defines a closed cross-section extending in the vehicle width direction in combination with the wheel-arch-shaped portion and a vertical closed cross-section defining portion that defines a closed cross-section extending in a vertical direction in combination with the wheel-arch-shaped portion. The horizontal closed cross-section defining portion and the vertical closed cross-section defining portion intersect each other.Type: GrantFiled: March 14, 2016Date of Patent: April 25, 2017Assignee: HONDA MOTOR CO., LTD.Inventors: Masayasu Yoshida, Tomohito Kamada, Akira Haga
