Chapter 038: Water Droplets Ripples

Lu Zheng and his family really didn't understand cars, but they still wanted to see what the Geely Boyue and Dongfeng Shuaike introduced to them by Fang Yuan looked like before making a decision on whether to buy them or not.

The three of them returned to the left side of the dealership, and Fang Yuan led them to a white SUV first.

In fact, when Lu Zheng knew that the white SUV in front of him was Geely Boyue, his little heart had been surprised by the unusual front face shape.

The hollow-shaped grille, shiny chrome, expands from the inside to the outside from small to large, like ripples on the surface of a calm lake, and the shield-shaped emblem in the middle, like a stone thrown into the lake, stands firmly in the middle.

The profiled headlights on both sides are of equal height to the top of the grille and are tightly connected, with a silky smooth angle, giving people a feeling of unity.

The overall shape of the fog lamps and the chrome decoration run through the bottom, giving Lu Zheng a kind of illusion of déjà vu, and he thought for a long time before recalling, isn't it the jade Ruyi of ancient China?

"It's beautiful. Lu Zheng grabbed Fang Yuan's arm with one hand, and pointed to Geely Boyue in the distance with the other, happy like an old farmer who had never seen the world.

"Well, that's the 'ripple of water drops' grille, and the chrome trim strip of the front fog lamps in the shape of Huaxia Jade Ruyi.

The family-style shape composed of the two integrates Chinese classical elements and international aesthetic trends, and the overall appearance looks more concise, with more distinct edges and corners, but also dynamic and exquisite. "To be honest, Fang Yuan also likes Geely Boyue's family-style front face, the original 'water drop ripples' grille, and the jade Ruyi-shaped front fog lamp chrome trim, maverick appearance, in terms of recognition, no less than BMW's kidney grille.

After looking at the front from a distance, Lu Zheng walked directly to the side of this Geely Boyue and stood still.

The black windows and the black B-pillars, C-pillars, and D-pillars are completely blackened from the white A-pillars, completely isolating the roof with a bright silver fit-fitting luggage rack from the body, giving the illusion that the roof is suspended in the air.

"It's called a floating roof, and it enhances the visual effect in terms of space. Fang Yuan told Lu Zheng and his wife that many models are now designed like this, which is very trendy and fashionable, and very high-grade.

Finding that Lu Zheng liked the appearance of Geely Boyue very much, Fang Yuan pointed to the waistline below and enthusiastically introduced him: "This is called the cheetah waistline, with the suspended roof above, the dynamic streamlined design highlights the unique sporty atmosphere of SUV models." ”

"Look at the back. Fang Yuan told Lu Zheng that the shape of the rear of the car is not as amazing as the front, but the rear bumper of Boyue is widened and raised, giving people a sense of security that is strong and shilang.

Double-sided dual exhaust, special-shaped red taillights, 18-inch double five-spoke lightning wheels, dazzling, dynamic and smooth, full of fashion, creating a visual effect that highlights the sense of power of the SUV.

In short, the exterior design of this Geely Boyue is a perfect integration of traditional culture and fashion trends, but it is not a little abrupt, giving people a coordinated and comfortable feeling.

"Good, good, good. Lu Zheng and his wife were completely conquered by this Geely Boyue in appearance, and they said a few words 'good' with a smile.

After introducing the appearance, Fang Yuan was about to open the main driver's door to let them see the situation in the car, and suddenly, Lu Zheng opened the passenger door first.

Fang Yuan thought that Lu Zheng wanted to get into the car, so he stopped and waited for him to check it out for himself before he continued to introduce.

Unexpectedly, Lu Zheng didn't have the slightest intention of getting into the car, and closed the door with his hands heavy.

With a dull sound of "bang", Lu Zheng stood next to him and nodded, showing a satisfied smile, turned back to Fang Yuan and said, "The quality is good." ”

Lu Zheng seemed to be unfinished, and opened the remaining three doors one by one, closed, and the front and back doors were all opened and closed for a test, and then stopped satisfied.

"What, good quality?" Fang Yuan was stunned, you don't look at the interior, you don't look at the chassis, you don't look at the suspension, just open the door and close it again, how do you know that the quality is good?

Fang Yuan smiled bitterly, it was the first time he had seen such a car inspection.

"Every car closes differently, and that's how we check the quality of the car. Seeing that even Fang Yuan didn't know what he was doing, Lu Zheng raised his head arrogantly and began to give Fang Yuan science popularization, the more dull the sound when the door closed, the better the quality and materials of the car.

"Oh?" Fang Yuan's eyes widened in sudden realization, and he didn't know whether to cry or laugh because of Lu Zheng's thoughts and words.

After taking a few deep breaths, Fang Yuan gradually soothed his frightened little liver, and lowered his head and thought for a while before he said to Lu Zheng: "The sound of the car door closing can indeed be used as a criterion for judging the quality to a certain extent, but it is very incomplete, and the limitations are very large. ”

"Wouldn't it? It was the old driver who had been driving for decades who told me the trick, what did he lie to me?" Lu Zheng was very unconvinced, yes, he was indeed unconvinced, thinking that Fang Yuan was young, how could he compare with those old drivers in terms of experience?

"Shut up, you listen to Fang Yuan first. Before Fang Yuan could explain, Zhao Fang on the side slapped her husband on the back of the head, asking him to listen to what Fang Yuan had to say.

"Okay, let Fang Yuan speak first. Lu Zheng touched the back of his head and retreated again and again to avoid his wife's claws.

"To measure the quality of a car, the most important thing is to look at the three major parts of the car. Fang Yuan's eyes widened when he saw Lu Zheng in confusion, knowing that he obviously didn't understand what the three major parts of the car meant.

The three major parts of the car refer to the engine, gearbox and chassis of the car.

For general models, the manufacturing cost of the three major parts of the car can account for about half of the total price of the whole car.

In order to make Lu Zheng understand, Fang Yuan deliberately gave an example, that is, people often say that buying a Honda is buying an engine and giving away a car.

Although this analogy is very inappropriate, it also proves to a certain extent that the three major parts of the car are important.

The three major parts of the car account for half of the manufacturing cost, and the rest is the interior, other electronic equipment, mechanical equipment and so on.

As for what Lu Zheng said, judging the quality of the model by the sound of closing the door, Fang Yuan felt that it was a bit exaggerated.

Even if the quality can be judged, it is only the quality of the door, the sealing effect of the door, etc., and the quality of the three major parts of the car, the interior, electronic equipment, and mechanical equipment, and there is no half-dime relationship.

"Wait, you said that the sound of the door closing has nothing to do with the quality of the car, can you tell me more about it?" Fang Yuan's words broke Lu Zheng's common sense for more than ten years, making him a little unacceptable for a while, and he was about to be confused.

"I'll tell you about the construction of the doors, and you'll see why the sound of closing is different for every model. ”

Fang Yuan opened the main driver's door of this Geely Boyue, pointed to the door hinges and said: "There are two types of door hinges: stamped and cast. ”

The stamping parts have a thin structure, simple manufacturing, low cost, less materials, and are connected by fixed shafts, which are more used in Korean models.

The door hinges of European and American cars are cast, and the parts are strong and integrally molded, which is expensive and has a large safety factor.

Geely Boyue's door hinges are European and American style casting.

Lu Zheng and his wife hooked their heads to take a closer look, and sure enough, as Fang Yuan introduced, the door hinge parts of this Geely Boyue were cast and molded at one time, which looked very thick and large, and it was certainly safer when it was hit.

"I know that door hinges are divided into cast and stamped, but what does this have to do with sound?" Lu Zheng's thinking still did not change, and he questioned very stubbornly.

"Shut up, you just have to listen honestly. Zhao Fang slapped Lu Zheng on the back of the head again, preventing him from interrupting.

I'll go on and I'll summarize it later. Fang Yuan patted the car door and told Lu Zheng and his wife that there are also two manufacturing methods for the car door.

One is the integrated stamping type commonly used in European and American models, and the other is the welding type commonly used in Korean models.

The welding type is also the non-full frame type, which is to combine the cut parts together by welding, and the manufacturing process is complex, but the materials are saved and the cost is low.

The one-piece stamping type, that is, the full-frame type, commonly used in European and American models, is formed at one time using a whole piece of material and stamping.

The full-frame manufacturing process is simple, and the manufacturing cost is high compared to the welded type that wastes raw materials, but it is more secure in terms of safety, after all, the full-frame door is stronger when impacted.

The door of this Geely Boyue is a welded type commonly used in Korean models, but the door weld is covered by a black rubber block.

In addition to the difference in the way the door hinges and doors are made, there are also side impact beams inside the doors that cannot be seen from the outside.

The function of the side impact beam is the same as that of the front and rear impact beams of the body, which is to protect the body in the event of a low-speed collision.

There are three types of side impact beams.

Korean models commonly use tubular side impact beams, while European and American models have U-shaped or W-shaped side impact beams, and there is no side impact beam.

The side impact beam inside the door of this Geely Boyue is a tubular side impact beam commonly used in Korean models.

Secondly, there are reinforcing ribs, soundproof cotton, moisture-proof sealing plates and membranes.

Some models of stiffeners have them, and some don't.

Some soundproof cotton is non-polluting virgin cotton, some are recycled cotton, and some are not at all.

As for the moisture-proof sealing plate \ membrane production process that plays the role of moisture-proof sealing, the materials are strange, and it will be explained to Lu Zheng and his wife for a while, so I will skip it and not go into details.
