Abstract

PROBLEM TO BE SOLVED: To bring a strong downforce to an automobile, a stability of the vehicle, and a small air resistance in a space-saving manner. SOLUTION: A shaft 1 equipped with a fan that can be stored in a vehicle is provided, and when the fan is stored, the airflow on the bottom surface of the vehicle flows as it is, and when the fan is deployed, the shaft 1 is rotated so as to accelerate the airflow on the bottom surface of the vehicle.

Description

The present invention relates to a vehicle structure for generating a strong downforce, stabilizing a vehicle, and reducing air resistance in an automobile in a space-saving manner.

Conventionally, an automobile having an aerodynamic device or structure based on the physical basis of obtaining a downforce by a pressure difference applied to the upper surface of the vehicle while the space on the lower surface of the vehicle is in a negative pressure state, is generally a funker (for example, Patent Document 1). (See) is known.

However, the fun car has a problem that a large space is required on the bottom surface of the vehicle when the fan is installed on the bottom surface (for example, see Patent Document 1), and when the fan is installed on the rear surface (for example, Non-Patent Document 1). (See) There is a problem that the space behind the vehicle is squeezed and space for the trunk etc. cannot be obtained.

Further, not limited to the fan car, there is a problem that the vehicle becomes unstable and causes a time loss when running on a course with many undulations.

Further, not limited to the fan car, there is a problem that the air resistance is often improved when trying to improve the downforce.

The present invention relates to a vehicle structure that solves the above-mentioned problems of the conventional downforce generator and structure, that is, saves space, generates strong downforce, stabilizes the vehicle, and reduces air resistance.

The present invention is a vehicle provided with a shaft equipped with a retractable fan, in which the airflow on the bottom surface of the vehicle flows as it is when the fan is retracted, and the shaft is rotated so as to accelerate the airflow on the bottom surface of the vehicle when the fan is deployed. It is a vehicle structure.

Due to the nature of the fluid, when the airflow on the bottom of the vehicle is accelerated by the fan, the pressure applied to the bottom of the vehicle becomes smaller, a pressure difference with the top of the vehicle is created, and a downward force, that is, downforce is generated in the vehicle.

In addition, the gyro effect generated by the rotation of the shaft has the effect of stabilizing the vehicle.

In addition, as a reaction to send air to the rear, there is an effect that a thrust to the front can be brought to the vehicle. From a different point of view, this can be regarded as a decrease in air resistance.

Further, since the shaft and the fan are provided with the retracting function, the effect of the above invention can be realized in a small space, and further, there is an effect that the vehicle height (minimum ground clearance) can be secured when necessary such as at the time of vehicle inspection.

It is a perspective view which showed one Embodiment of the automobile which concerns on this invention. It is a perspective view which showed one Embodiment of the automobile which concerns on this invention.

Fans A (Figs. 2 and 14), B (Figs. 2 and 15), and C (Figs. 2 and 16) are all folded inside the vehicle as shown in Fig. 2 during normal driving where downforce is not required, such as when driving in the city. Stored in. At this time, the bottom surface of the vehicle becomes approximately flat and the vehicle height (minimum ground clearance) can be afforded, so that it is possible to solve the situation where the vehicle height is required at the time of vehicle inspection. Further, since the present invention can be carried out as long as a storage space for the elongated shaft 13 is prepared on the bottom surface of the vehicle, the degree of freedom in vehicle design is not impaired.

On the other hand, when it is desired to improve the kinetic performance of an automobile, such as when driving on a circuit, the shaft 1 is projected toward the ground, the fan wings 2 to 10 are deployed, and the power source such as an engine or a motor and the shaft 1 are used. The downforce can be obtained by increasing the flow velocity of the air on the bottom surface of the vehicle and reducing the pressure applied to the bottom surface by linking and rotating at high speed.

Further, the rotation of the shaft 1 causes a gyro effect to stabilize the vehicle, but since this stability is proportional to the mass of the shaft 1, a heavy material may be used for the shaft 1.

Further, since the gyro effect is not always exhibited without a fan, the shaft 13 in the shaft retracted state (FIG. 2) may be configured to rotate.

Further, as a reaction of vigorously discharging air backward in the traveling direction, the vehicle obtains a force in the traveling direction, that is, a thrust. From a different point of view, this can be regarded as a decrease in air resistance. Therefore, when you want to reduce the air resistance even on a general road such as when driving on a highway, the shaft 1 is projected toward the ground, the fan wings 2 to 10 are deployed, and the power source such as an engine or motor is linked to the shaft 1. It may be configured to rotate at high speed.

Further, when power is transmitted from the front wheels to the rear wheels or from the rear wheels to the front wheels, the propeller shaft is often installed on the bottom surface of the vehicle body, so that the shaft 1 and the shaft 13 may also serve as the propeller shaft.

Since it greatly improves the kinetic performance of automobiles, it is useful as a structure for vehicles used in motor sports and as a structure for commercially available sports cars.
