Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

As shown in fig. 1 and 2, the tail assembly 100 of the embodiment of the present invention includes a bulkhead 1, an upper air bag 2, and a lower air bag 3, the bulkhead 1 being adapted to extend in a width direction of a vehicle, the upper air bag 2 being provided on an upper surface of the bulkhead 1, the lower air bag 3 being provided on a lower surface of the bulkhead 1, the upper air bag 2 and the lower air bag 3 being capable of changing shape by inflation and deflation.

The upper air bag 2 and the lower air bag 3 are in an inflated state, wherein the upper surface of the upper air bag 2 forms an arc surface, the lower surface of the lower air bag 3 forms an arc surface, and the lower air bag 3 is in a deflated state, the upper air bag 2 is in a volt-fit on the upper surface of the partition board 1, and the lower air bag 3 is in a volt-fit on the lower surface of the partition board 1.

When the upper air bag 2 and the lower air bag 3 are in a deflation state, a plane is formed and is clung to the upper surface or the lower surface of the partition board 1, when the upper air bag 2 and the lower air bag 3 are in an inflation state, the upper air bag 2 and the lower air bag 3 are bulged to form cambered surfaces, and according to different inflation amounts, the radian of the cambered surfaces formed by the upper surface of the upper air bag 2 and the lower surface of the lower air bag 3 can be adjusted. The upper air bag 2 and the lower air bag 3 can be made of elastic materials similar to rubber and have certain wear resistance, and the upper air bag 2 and the lower air bag 3 can be inflated by an external air pump or by an air pump carried by the vehicle 200.

It should be noted that, when the upper air bag 2 and the lower air bag 3 are in an inflated state, they may be in a non-cambered shape, so long as the distance of the upper surface of one air bag is ensured to be greater than the distance of the other air bag in a deflated state.

When the airflow passes over the upper and lower surfaces of the tail assembly 100, the airflow passes over the upper and lower surfaces at the same time, and if the upper surface is longer than the lower surface, the airflow will have a greater flow rate than the lower surface according to the basic kinematic formula s=vt, and then a pressure difference will be generated according to the bernoulli theorem (incompressible, when an ideal fluid flows along the flow tube at steady flow, the flow velocity will increase, the static pressure of the fluid will decrease, and conversely, the flow velocity will decrease, the static pressure of the fluid will increase), resulting in an upward lift. Similarly, if the lower surface of the tail assembly 100 travels longer than the upper surface, downward pressure may develop.

The tail assembly 100 of the embodiment of the present invention has two working modes, the first working mode is that the upper air bag 2 is in a deflated state and the lower air bag 3 is in an inflated state, based on the above principle, downward pressure is formed, and the working mode can increase the grip force, improve the steering performance of the vehicle 200, and is suitable for the small-sized fuel vehicle 200.

The second working mode is that the upper air bag 2 is in an inflated state, the lower air bag 3 is in a deflated state, the working mode can generate lifting force, the pressure of the vehicle 200 to the ground is reduced, and therefore friction force is reduced, the working mode is suitable for the new energy vehicle 200, due to the existence of a power battery, the dead weight of the new energy vehicle 200 can be increased, the stability and the control of the vehicle 200 can be greatly increased, the functions of a traditional tail wing are greatly reduced, the energy consumption of the vehicle 200 can be reduced by using the tail wing of the second working mode, and the cruising duration of the vehicle 200 is improved. According to the tail assembly 100 provided by the embodiment of the invention, the inflatable upper air bag 2 and the inflatable lower air bag 3 are arranged, so that lifting force and pressure can be formed in a targeted manner for different vehicles 200, and meanwhile, the tail assembly is suitable for the traditional fuel oil vehicles, new energy vehicles 200 and hybrid vehicles 200, and has a wide application range.
