Coquettish Rebirth

What is the other solution?There's really no other solution!Let’s take suv as an example. Now that the sales of suvs in the market have just entered a trough, the suv craze in the United States in the 90s caused car manufacturers all over the world to go to the United States to promote their suvs. As a result, in 05, bang!With the rise in oil prices, Americans have honestly started to use fuel-efficient cars, and they are driving fewer suvs. Even if they buy suvs, they basically buy Japanese rav4s or cvr and other fuel-efficient suvs from Toyota and Honda.And what are these suvs selling?What it sells is that it can do everything, and it is more fuel-efficient!It can be said that what is sold is a panacea configuration, and to be honest, the American people did not expect Japanese suvs to be able to drive fast!So it’s enough to be able to drive at high speeds. Who wants to use it to optimize aerodynamics like a sports car?

It can be said that in such an era of soaring oil prices, neither consumers nor car manufacturers expected that there would be an suv with strong racing capabilities on the market!In this way, how could the commander have a relevant design plan?And seriously, unless it is a Porsche Cayenne, a Maserati or a Lamborghini to make an SUV, how can there be such a design to avoid the rear vortex?Even if it is an SUV of BMW and Mercedes-Benz, it is more positioned as a luxury SUV, rather than a particularly strong racing ability!This is a bit like what it is, a bit like the mobile phone industry in the original historical time and space. Before Xiaomi appeared, how many mobile phone manufacturers in the past would optimize their mobile phones for running scores?No!Even if many manufacturers advertise their own configurations, they are just promoting it. High running scores are the best, and it doesn’t matter if the scores are not top-notch.As a result, after Xiaomi came up with the running score, all of a sudden consumers seem to focus on the running score, as if the mobile phone with a bad running score is worse than other phones!

same.Our suv is going to create an era of running points, so before us, various suv manufacturers may not care much about the acceleration of [-] kilometers. , After all, manufacturers and consumers will think that it is okay to drive an SUV to go racing.Isn't this a pain in the ass?But the problem is that manufacturers don't realize one thing - many times consumers won't drive suvs to go racing, but it doesn't mean consumers won't be willing to buy an suv capable of racing at the same price!Yes, many times for consumers, it is one thing to have this function, but another thing to use it!

Therefore, if we start such an era of suv running points, I believe that many consumers who can afford to buy a suv with a price of 10 US dollars or 10 euros will start to pay attention to the 1-kilometer acceleration performance of the suv!And we who are the instigators.When other companies do not have the relevant design scheme of suv rear vortex, it must be developed as the No.[-] in the world!So where do we have solutions from other manufacturers?If there is no other design plan, how can we do it?After all, Jia Hongjian is not an automobile designer, he has not learned relevant knowledge, and he has not done front-line design work for more than ten years. To be honest, let him give some examples at once. The tail vortex, I really can't think of it!

What's the matter?What else can I do, there is no related design for suv.Let's look for other models!First of all, Jia Hongjian took aim at sports cars, ordinary sports cars.There is really no solution on the roof to improve the wake flow - because sports cars are low, and even if they don't have a luggage compartment, even if they are only two-seat sports cars, they still try to make the rear half of the cockpit as similar to our current SUV. Partially elongated so that there is a gently descending curved surface behind the roof, which allows the wake to flow down smoothly.In this way, the eddy current area behind the natural car of the sports car is just small, and the natural resistance is just small!At the same time, the sports car has a low floor, and the overall aerodynamics are in line with the aerodynamics. No matter how fast the speed is, there will be lift, and the car will fly. That's why many sports cars have an aerodynamic kit on the tail of the car.To put it bluntly, this kit is a reverse wing, which is to generate downward pressure when the wake passes through.Thereby the car is pressed down to prevent the car from flying.Even Jia Hongjian still remembers the high-speed rail in our country, the design speed limit can reach 350, and then there are some side depressions and protrusions in the design of the front, which is to guide the airflow to generate a downward pressure on the front of the car, so as to prevent the front of the car from driving Generate lift!

kindness?Tail?Suddenly Jia Hongjian seemed to realize something!He quickly checked the pictures of other manufacturers' SUVs on the Internet, and found that many manufacturers' SUVs had a small window on the rear door, and a small sun visor as shown in the picture was also arranged!The purpose of such a sun visor is definitely not to block the rain, because some suvs also have wipers on the windows of the rear doors.Then the use of this small board can only be used to prevent direct sunlight, at least Jia Hongjian did not see any benefit in terms of aerodynamics-because such a slightly raised transparent board can only be lifted from the roof of the car. The incoming airflow is directed to the place where there is nothing behind the car, which will definitely cause vortex generation behind the car!The resistance must be greater!Then I think it only has the function of sunshade!Want to come to prevent the sun from shining through the rear window on the top of the rear passengers in the car?Regardless of whether it is such a function or not, Jia Hongjian looked at such a small panel of these SUVs, and then looked at the aerodynamic kits of the sports car, and suddenly felt an inspiration!

What he thought of was not about installing a rear spoiler on our suv, what he thought of was the function of the rear spoiler!What is the function of the empennage? When the airflow passes by, because one of the upper two sides is drummed and the other is flat, the airflow will flow faster on the flat side and slower on the drum side.The difference in flow velocity between the fast flow and the slow flow leads to the difference in air pressure on both sides, and then the difference in air pressure leads to the effect of force!Generally, the wings of an airplane are bulging on the top and flat on the bottom, so when the speed is fast enough, it can generate upward lift!As for the rear wing aerodynamic kit of the sports car, it is the other way around.And what if we make a small thing like an aerodynamic kit in the position of the sun visor like an suv, but instead of making one side bulging and the other flat like a wing, what will happen?

If such a kit is not horizontal and vertical like the rear wing of a sports car, but narrower in width than the car.The length is only a dozen or twenty centimeters, and the whole is still consistent with the curve of the rear of the car?Such a kit can be placed on the upper part of the rear door window, so that the airflow from the roof that has already shaken at the position of the rear door window will vibrate, but after encountering such a kit, will it be rearranged according to the order? The curve of the rear roof?Will this improve the rear vortex problem to a certain extent?Such an idea came out of nowhere, and no one told Jia Hongjian that it was so feasible.But no one told him that this was not possible!Maybe what he did is just a joke in the eyes of professionals, but he, the boss, didn't slap his head and told the people below to change it like this. He just thought of such a method and asked professionals for advice. Such a boss is enough Is it easy to learn enough to make progress?Is it shameful enough to ask?

After thinking of this, Jia Hongjian immediately began to revise the sketch.On the next morning, he took the sketch and went to Mr. Guo Konghui, "Grandpa, I thought of something new last night, what do you think..." As the boss.Jia Hongjian also knew that it would be annoying for the people below to see the boss's idea changed every three days, so he specifically said to our national master Mr. Guo: "Mr. , it can also be used on the next generation of SUVs, I just scribble in my spare time..." Look, how considerate is our boss?Jia Hongjian himself felt that the people below would be so moved when they heard this, they wanted to hug him!

As a result, after the old man heard this, he laughed and said before Jia Hongjian finished speaking: "Mr. Jia, look at what you said, we know your ideas. There are often magical strokes! Our company's automobile business You have contributed the most to the development up to now? You have new ideas for me to see. How can I still complain? You are not allowed to do this in the future. If you are so polite, you will be scolding me. You just scold me. I don’t know. How about it!" After speaking, the old man took Jia Hongjian's new drawing and began to look at it. The first thing he saw was the changes in the front of the car in the three-view!Jia Hongjian's modification is quite big, it is equivalent to overthrowing the design of the front of the car and starting over!And this overturned and redesigned front of the car... the old man was silent for a long time after looking at it!

The old man looked silent for a while, which made Jia Hongjian feel a little guilty.Don't let the things we designed not work, the old man doesn't know what to say or not? "Old man, the direction of my design is based on fighter jets..." Jia Hongjian had just said half a sentence, when the old man suddenly realized: "Yes, yes, fighter jets! I'll just say this I seem to have seen the one taught by the Lens religion somewhere. It was the stealth fighter-bomber of the United States, right? It went to Yugoslavia to bomb it, right? Was it the plane that bombed our embassy? What? It was a missile bomber. Our embassy? Oh, regardless of this, I said that the appearance of this car looks like that in a science fiction movie, I always feel like I have seen it somewhere before, and I can’t remember it after thinking about it for a long time!”

Hiss... Does this mean our design is okay?Before Jia Hongjian opened his mouth, he saw the old man nodding and said, "Mr. Jia, you young people know what foreigners like, and you know modern aesthetics. I don't think it's bad! The front and rear wings The sub-boards are all surrounded by the front, which means that the side and the front are fused together? Well, the headlights are also placed at the ridge line where the sides are fused. The front of the car looks fierce! It feels like a high-tech beast!" The old man quickly sensed the soul of Jia Hongjian's new design!People of the new generation like Jia Hongjian, not to mention being contaminated with Western culture since childhood, just watch the nba and play football. All kinds of foreign football styles are fierce, so when Jia Hongjian designed the car, he also tended to It is designed to have a fierce appearance!Potential consumers will definitely like it - don't Americans generally pay attention to being fierce like this?Even if the old man is not vicious anymore, how could a non-violent old man buy our car?Why don't people buy Rolls-Royce's solid and heavy ... obviously outdated old-school design?
