Keijiro Ohshima

Title: Keijiro Ohshima and Vehicle Safety Innovations.

Introduction

Keijiro Ohshima is an inventor associated with Toyota, Japan. His patent work includes vehicle designs addressing fuel-cell packaging and the protection of high-voltage components during collisions. The supplied data lists 4 patents.

Latest Patents

Ohshima’s recent patent work includes two vehicle technologies focused on packaging and collision safety.

- **Fuel cell vehicle.** This design positions fuel-gas tanks in front of and behind the motor drive unit, with each tank oriented across the vehicle’s width. The arrangement places the tanks’ ends outside the high-voltage wiring portion and aligns them with a tire-wheel assembly in the vehicle’s front-to-rear direction.

- **Vehicle with improved suppression of high voltage under collision load.** This design places a high-voltage component inside an electrical-device case near one side of the vehicle. Under a sufficiently large front-to-rear collision load on the fuel tank, the tank is configured to rotate horizontally around one end, bringing its opposite end into contact with the other side of the electrical device.

Career Highlights

The supplied information associates Ohshima with Toyota Jidosha Kabushiki Kaisha, commonly known as Toyota Motor Corporation, and Denso Corporation. His described patent work reflects attention to fuel-cell vehicle layouts and the management of collision forces around high-voltage equipment.

Collaborations

The listed coworkers include Daiki Nishiumi and Kenichi Fujiki. The available information does not specify their roles in the patents or the nature of their collaboration with Ohshima.

Conclusion

Keijiro Ohshima’s documented inventions address practical challenges in fuel-cell vehicle design, particularly component placement and collision-related protection of high-voltage systems.
