Publication number: 20230347726Abstract: A battery unit mounting structure for a vehicle includes: left and right rear frames extending along a front-rear direction; a battery unit including a housing in which a battery is housed and which is disposed between the rear frames, and a battery frame provided with protruding portions extending in a vehicle width direction and protruding in the vehicle width direction beyond a space between the rear frames; and reinforcing plates provided permanently with the rear frames respectively in regions in which the rear frames and the protruding portions are respectively fixed to each other. Each of the reinforcing plates extends in the front-rear direction of the vehicle in a corresponding one of the regions in which the rear frames and the protruding portions are respectively fixed to each other. The battery frame and each of the rear frames are fixed to each other at first and second fastening portions.Type: ApplicationFiled: April 14, 2023Publication date: November 2, 2023Inventors: Yosuke OISHI, Takayuki TOKUNAGA, Keita FURUKAWA

Patent number: 10358048Abstract: An onboard battery includes predetermined members such as battery modules, and a housing case. An internal space of the housing case is partitioned by a partition plate into an upper space and a lower space in which the predetermined members are disposed, and the battery modules are disposed below the partition plate. The housing case has a bottom surface on which the battery modules are disposed, a front surface that has a front-side tightening part, and a rear surface that has a rear-side tightening part. The partition plate has a partition base that partitions the internal space of the housing case into the upper space and the lower space, a front-side fixation target part that is continuous with a front end of the partition base, and a rear-side fixation target part that is continuous with a rear end of the partition base.Type: GrantFiled: April 13, 2017Date of Patent: July 23, 2019Assignee: SUBARU CORPORATIONInventors: Toshiyuki Hara, Takayuki Tokunaga

Patent number: 9981541Abstract: A battery module is mounted in the rear of a vehicle body and attached to at least one rear side frame extending rearward in the vehicle body such that the rear side module protrudes rearward beyond the battery module. One or a plurality of slope members is provided at the rear of the battery module. Each of the slope members forms a frontward rising inclined surface that protrudes above the rear side frame at the rear of the battery module.Type: GrantFiled: March 17, 2015Date of Patent: May 29, 2018Assignee: SUBARU CORPORATIONInventors: Yu Onodera, Junya Okamura, Takayuki Tokunaga, Yasunori Mashio

Patent number: 9975416Abstract: Some vehicles are equipped with an onboard battery. The onboard battery includes a holding frame having a frame-shaped part, a housing case that is held by the holding frame, being inserted into the frame-shaped part, and battery modules housed in the housing case. For such a vehicle with the onboard battery, the vehicle body structure includes a displacement restricting part and a disposition depression. The displacement restricting part restricts an upward displacement of the onboard battery in a collision from behind is formed at a position facing a front end portion of the holding frame. The disposition depression is formed in a floor panel and the onboard battery is disposed to be at least partly inserted into the disposition depression.Type: GrantFiled: September 29, 2016Date of Patent: May 22, 2018Assignee: SUBARU CORPORATIONInventors: Toshiyuki Hara, Takayuki Tokunaga
