Description

Technical Field

[0001] The utility model belongs to the technical field of automobile design, in particular to a clay car model with a detachable tail wing. Background Art

[0002] In the process of body design, the production of physical clay models is a necessary step. During the entire design stage, clay models of various proportions must be made. The role of the scale model is to make the selected renderings three-dimensional, to reflect and correct the parts that are not shown or not yet clear in the renderings, and to further clarify the concept of the vehicle model. The physical model can make the characteristics of the product more realistic and distinct. In the process of model making, the design goals, structure, and productivity can be analyzed and studied at the same time. On the premise of meeting the design requirements, the model can be improved to improve the appearance design of the car.

[0003] When a car is driving at high speed, according to the principle of aerodynamics, it will encounter air resistance during driving, and aerodynamic forces in three directions, namely longitudinal, lateral and vertical rising, will be generated around the center of gravity of the car at the same time, among which the longitudinal direction is air resistance. In order to effectively reduce and overcome the influence of air resistance when the car is driving at high speed, people have designed and used car tail wings, whose function is to make the air produce a fourth force on the car, that is, to produce a larger adhesion to the ground, which can offset part of the lift, effectively control the car's floating, reduce the wind resistance coefficient accordingly, and enable the car to drive close to the road surface, thereby improving the driving stability. That is, the function of the car tail wing is to make the air resistance form a downward pressure when the car is driving at high speed, try to offset the lift, effectively control the downward pressure of the airflow, reduce the wind resistance coefficient accordingly, and increase the high-speed driving stability of the car; since the tail wing can reduce the air resistance of the car, the installation of a tail wing on a high-speed car is also helpful for saving fuel; at the same time, it also makes the appearance of the car more beautiful and plays a certain decorative role.

[0004] However, when designing a car, on the one hand, it is necessary to carry out vehicle installation tests on the tail wings of different schemes, and on the other hand, it is necessary to measure the stress of the tail wings.
