Why are convertible owners not afraid of the cold and how to solve the problem of driving a convertible?

The launch of the convertible version of Wuling Hong Guang MINIEV will surely fulfill the "convertible dream" of many car enthusiasts. A car that can open the ceiling on a sunny day and feel the fresh air and sunshine will really make people feel very comfortable. However, will the convertible blow when driving, and will it "freeze" when the temperature is slightly lower?

Drivers who like to open windows for ventilation may be most worried about this problem. As long as you open the windows on both sides, there will be a strong airflow, and the whistling wind is really noisy; Then it seems better to open the ceiling again. However, these problems can basically be solved in a convertible with high design level.

This picture shows the airflow direction of the convertible, and the concern about the strong wind blowing overhead is actually unnecessary; The convertible sports car is always designed strictly according to aerodynamics, and the angle of the front gear, the length of the driver's seat and the direction of airflow must be tested. That is to say, in the normal driving process, it is necessary to ensure the airflow from the front to the "roof", "skip" the protective structure of the driver's seat and the rear row, and then sink to the trunk position.

Of course, the sinking curve is linear, so there is a problem-speed, gravity, airflow intensity.

The convertible is a very interesting design, and the wind noise experience at different speeds will be very different.

The reason is very simple, that is, air will also be affected by gravity (pull down); When the vehicle speed is too low, the airflow intensity on the roof is not strong, and the airflow may "pass by" under the action of gravity, but the airflow is not strong at this time, so the driving experience will be quite good.

With the increase of vehicle speed, the airflow speed on the roof is faster, and the influence of gravity on airflow is controllable. Therefore, the experience is better when the convertible drives faster, but the overall wind noise is still louder than closing windows and sheds, especially when driving on urban roads, there will be about 70 decibels of road background noise, which is higher than many commuter vehicles120km/h/h.

"aircap-" is the standard configuration of many sports cars. When the ceiling is opened, the spoiler will open, and the angle can be adjusted according to the vehicle speed. This board can make the airflow always skip the driver's seat, so the driving experience will be much better.

Moreover, the spoiler also has the design of "insect net", which has the same function as the front spoiler or insect net of many vehicle skylights; Can effectively prevent flying insects from flying into the car in low-pressure weather. At this point, the "wind noise" of the convertible should be beyond doubt. It is undeniable that its noise intensity will indeed be greater, but at the same time it will get sunshine, air and "turn around". You can't have your cake and eat it. If you lose it, you get it, and if you get it, you lose it.

Looking back at the Hong Guang MINIEV convertible, this car seems to be just a modification of the ordinary macaroon version; However, judging from the front block, it has actually been redesigned, and the feeling of tilting is somewhat different. Therefore, the design of this car should also be adjusted for the convertible design, and the airflow control during driving should be very good.

After all, the size of this car is like a "squeaky bean". If the speed is slightly higher, the airflow can "top off"; That's why the Hong Guang Minev convertible has not been questioned. In fact, there is still a size advantage. Moreover, this car is pure electric drive after all, and there is no internal combustion engine noise of a fuel car when commuting at medium and low speeds. Only wind noise and road noise can improve the driving quality.

Finally, it needs to be explained that the convertible is still guaranteed, there are two kinds.

Hard-top convertible is basically a performance sports car that pursues the ultimate driving pleasure, while soft-top convertible is more "casual style"; When driving at medium and low speeds, you don't worry about wind noise when opening the roof and side windows. When the vehicle speed is slightly higher, the side window can be raised. If you want a good mute effect, turn off the ceiling. Driving in special weather will always turn off the ceiling.

The soft-top convertible used by Hong Guang MINIEV, the texture of purple color matching, and electric folding are of course the basic configuration; So there is no problem with this car. The only uncertain factor now is the price. If the price is set in the range of 60-80 thousand, it will be very attractive. It is estimated that it will be difficult to be popular if it exceeds 65438+ 10,000. After all, it is mainly produced by Wuling, a low-end micro commercial vehicle, and its cruising range is also very short.
