When buying a car, everyone has their own different needs and concerns. Many people are curious, why can't those practical family car scooters be designed into the cool appearance of a sports car? Here, the editor will explain to everyone from the beginning of the design of a car and the influence of the appearance on the function.
Each homecarOEMs all have a market research department whose duty is to visit customers and ask them what kind of car they want to own. Different groups gave different feedback. Young singles would want to own a cool sports car, and a family of three would want to own a car or off-road vehicle to travel, travel to work, etc. The company needs a commercial vehicle to receive his customers. Function determines ergonomics, and ergonomics restricts styling design. Therefore, it is necessary to design different models to meet the needs of different customers.
The family car needs not only five people, but also luggage.Back rowSeatThe height of the head of the person above determines that his roof cannot be pushed down like a sports car. The trunk does not need to be that high, so you can press it down to design a car butt, at the expense of a part of the head space of the rear passengers.
Since the sports car has no restrictions on the rear passengers, after the head space of the driving position is passed in the styling design, you can boldly press down and the roof slides back. If it is a four-door sports car, or has a rear row, the space in the rear row will be very cramped.
In addition, there are aerodynamic characteristics. When a car is driving at high speed, the air resistance is much larger than the resistance of the road surface and mechanical transmission. The air resistance is related to the driving speed, the windward area of the car, and the drag coefficient.
Therefore, when designing the shape of the car, the stylist needs to consider the influence of the shape of each component on the wind resistance. The transition of large curvature, the variable height ducktail, the chassis cover, the front air inlet, the large curvature reflector, etc. can reduce the wind resistance coefficient; And reducing the height of the vehicle is equivalent to reducing the cross-sectional area, and it is also conducive to reducing air resistance, which also reduces the level of fuel consumption. Sports cars usually run on racetracks or other special runways. The speed is usually high. It is common to be above 200KM. It has high requirements on aerodynamic characteristics. However, the speed of family cars generally does not reach that high, so the requirements on aerodynamic characteristics are Is relatively low.
There are also ergonomics issues. Ergonomics is the convenience of the various parts of the car. Sports cars are mainly used for competitions and competitions, and this problem is usually not considered, but in family cars, ergonomics is a very important item in car design. The biggest impact of styling on ergonomics is the riding space. A sports car has a small riding space. If it is a four-door sports car, the rear riding space is very cramped, and the head will be rubbed against the roof of the car. It is also difficult for rear passengers to get on and off the car. And because the design of the family car is not so exaggerated, it will have a larger riding space, which will bring greater riding comfort and convenience of loading.
Next is the driving performance requirements. In most cases, sports cars are driven on better-quality paved roads, so the chassis is very low and looks relatively low. The design of this shape feels cool. The driving conditions of a family car are more complicated. It usually has to cross ditches and ridges, can climb mountains and wading, so the chassis is adjusted relatively high, and the shape is not as cool as a sports car, and the chassis of an off-road vehicle is adjusted higher. This is also the truth. .
The game theory states: “It’s not that designers are difficult to design cool models, and it’s not that Apple’s engineers were unable to design Apple 6. This is an economic problem, and product grading is a more reasonable solution. "
