A recently granted patent (Publication Number: US11878638B2) discloses a vehicle design that includes a unique heat shield plate configuration. The vehicle comprises a radiator with a fan, a driving seat positioned behind the radiator, and a dashboard with a meter located between the radiator and the driving seat. An engine unit, partially situated below the driving seat, extends further back than the front end of the seat. A heat shield plate is strategically placed between the radiator and the dashboard, oriented in the direction of airflow through the radiator. Importantly, the distance between the lower edge of the heat shield plate and the radiator's lower edge is less than the fan's diameter, ensuring efficient heat management.

Furthermore, the patent details additional features such as the inclination of the heat shield plate in a side view of the vehicle body, its size concerning the radiator fan area, and its mounting on the vehicle body frame. The design also incorporates left and right front wheel suspension devices, with the heat shield plate attached to specific components of the suspension system. Additionally, the vehicle body frame includes a cross portion along the upper edge of the heat shield plate, enhancing structural integrity. The patent further describes the positioning of the heat shield plate concerning other vehicle components like the dashboard, air cleaner, front wheel suspension device, and electric components, emphasizing the comprehensive integration of the heat management system within the vehicle design.
