What are gullwing doors like, and are there any advantages to them?

The gullwing door is opened upwards like the wings of two seagulls, and when closed, it is also folded down electrically, so the advantage of the door is that the door will look very high-end and handsome, attracting attention.

Gullwing doors are doors in the second row of the car that open upwards like seagull wings. The advantage of this type of door is that it has a large opening, which makes it easy for passengers to get on and off the bus.

Gullwing doors are like seagulls, winged doors, such cars are generally on sports cars, the appearance is cooler and more stylish, more in line with the aesthetics of young people, and this kind of door is also used in Tesla.

Gullwing door, as the name suggests, is the opening shape of the door resembles wings and gets its name, the extremely elegant way of opening the door is simply bursting, perhaps people's deepest impression of the gullwing door is carried on the Mercedes-Benz SLS AMG, but it has a history of more than 60 years.

What are the auspicious obstacles to the cars of the Gull Ji Heng Code Wing Door? Gullwing doors are available in Tesla (e.g., Model-X-SUV), Mercedes-Benz (e.g.,

Mercedes-Benz-SL-300), Pagani (e.g., Huayra), Xpeng (G3i), etc. Here's a brief overview of the rise of the Eurowing Gate:

1. The origin of the European wing door: The gullwing door first appeared on the Mercedes-Benz W194, when Mercedes-Benz thought that this kind of exaggerated gullwing door would be loved by Americans, but the number sold was not ideal. However, after several twists and turns, the road to full-scale mass production was finally opened.

2. The popularity of European wing doors: Today's cars are pursuing a sense of design, and in addition to maintaining a reasonable aerodynamic design, the body appearance should also reflect the beauty of its design. Many will be designed in terms of the front end, wheels, grille, light styling, rear wing, etc.

Gullwing doors are designed to be opened in the car. @2019

Suitable for supercars, handsome and stylish.

The so-called "gullwing door" is named after the hinges (attachment points) of the doors on the roof, and the doors open to resemble wings. The wing door was first invented by Mercedes-Benz in 1951, and it was originally designed to reduce the wind resistance of the door handle, but it is said that it was still forced to become a classic.

Compared with the most widely used side-pull doors, gullwing doors are very practical in many cases, in addition to pulling the wind. For example, in a small parking space, the side-pull door may not be able to open and close at a large angle because it is blocked by vehicles on both sides, while the upward gullwing door can be easily opened. The gullwing door style has also become a model for many supercars, such as the Pagani.

Butterfly doors, also known as butterfly wing doors, are a type of door style for supercars. The hinges of the butterfly door are mounted on the A-pillar or the fender near the A-pillar, and the door opens forward and upward through the hinge, and the door is raised diagonally like the wings of a butterfly, hence the name "butterfly door".

Ferrari Enzo, the Four Heavenly Kings Aaron Kwok also has one. The first model to feature butterfly doors was the Alfa Romeo 33 Stradale, launched in Monza, Italy, in September 1967. The car was first introduced in 1965, a total of 18 units left the factory, the top speed was close to 300 km h, and the acceleration of 100 kilometers was completed in seconds, making it one of the most expensive road sports cars at the time.

Interestingly, at the 1968 Paris Motor Show, Broadcom's genius designer Marcello Gandini used the same chassis to design the world's first scissor door model, the Alfa Romeo Carabo.

Sports cars and concept cars are not very suitable for ordinary family cars.

I think butterflies are more suitable for car supercars.

The butterflies of cars are more suitable for sports cars.

Scissor door: The so-called scissor door, that is, its hinges on the front fender, are named because the door opens like scissors.

Butterfly doors are suitable for sports cars and look better.

Generally sports cars and concept cars.

Sports cars and concept cars, of course.

That is, its hinges are on the front fender, so named after the scissor-like shape of the door opening.

In fact, gullwing doors are more suitable for racing.

I think the butterflies of cars are more suitable for sports cars.

Take a look at the design of these gullwing doors in Shengling, which one is your dish? This car is really good

Mercedes-Benz's classic 300SL features door hinges on the roof, and the two small doors open upwards like wings when pushed outward. The designers gave this type of door a catchy name--- gullwing door. The seemingly pretentious gullwing door was designed with practicality in mind.

Mercedes-Benz has adopted a number of designs that are different from traditional models in order to make the classic SL a good result on the field, among which the tubular frame to reduce the weight of the car while ensuring the rigidity of the body is an important feature of this car.

The tubular frame is combined into a sturdy structure around the SL bodywork, which makes the door thresholds high, leaving no room for traditional doors under the compression of the low roof. The legendary gullwing door was born by placing the door hinges on the roof and blending the doors into part of the roof, and finally adding a pair of hydraulic tappets as supports.

For a model like the 300SL that uses a small gullwing door, it has similar advantages to a scissor door, which can be opened and closed in tight spaces.

Gullwing doors aren't perfect either, and you can't have storage space on the sunroof or doors in order to open them coolly. The roof hinge layout also makes gullwing doors unsuitable for convertibles, and you need to be confident in your arm length and arm strength to choose a gullwing door car. After the rollover, the gullwing door also encountered the embarrassment that the scissor door and the butterfly door could not be opened, but fortunately, the latest Mercedes-Benz SLS AMG solved this problem with a special disengagement device.

The Mercedes-Benz SLS AMG has once again put the gullwing door in front of the world

However, the arrival of Mercedes-Benz SLS AMG solves this defect, and the 300SL of the space tube array frame adopts gullwing doors to ensure the strength of the car body, and when it comes to the SLS AMG of the load-bearing body, it has completely become a nostalgic complex to pay tribute to its predecessors, so it is necessary to overcome a large number of structural strength and safety problems. For example, in order to ensure that the car can escape when overturning, a ** device is installed in the door articulation mechanism, and when the vehicle sensor detects that the body is upside down, it will activate the ** device to blow the door open. It seems that it is not easy to recreate the classics.

The shape of the gullwing door is characterized by the fact that when the door is opened, the door holder stands on the top of the vehicle like the wings of a seagull, the upper part of the door is a part of the roof, the hinge of the gull-friendly wing door is arranged on the middle longitudinal beam of the roof, the upper part of the door bears most of the mass of the door, the structural design of the door frame is thick, and when the door is closed, the thickness of the upper middle of the door is basically the same as the thickness of the conventional top cover. The upper bezel of the door is thicker than the conventional top cover, which can easily affect the design and comfort of the driver's headroom.

The W194 was only a racing car, and Mercedes-Benz had no plans to mass-produce it at the time. But there was a car importer in New York, Max Hoffman, who used to be a race car driver. The performance of the W194 on the field has formed a huge attraction for him, on the one hand, he really wants to drive this car himself, and more importantly, he thinks that if this car is mass-produced, the American tycoons will definitely line up to pay.

Guess most of them are pompous Yankees who like this gullwing door. Later, Max Hoffman lobbied Mercedes-Benz to mass-produce the W194, Mercedes-Benz refused, and then Max used various means, and finally mass-produced, and the production version of the model is still the Mercedes-Benz SL 300, which is still known as the Mercedes-Benz classic car Xiaolu.

Before World War II, Mercedes was the dominant player in the European Grand Prix. After World War II, Mercedes-Benz, which was affected by the war, put aside its racing projects and withdrew from racing. It wasn't until 1951 that Mercedes' top brass decided to return to racing.

The return is a return, but Mercedes-Benz allocated a small budget for the racing project, and it is stated that it can only use the engine and gearbox on the Mercedes-Benz production car at that time, and cannot be redeveloped. Mercedes-Benz's production flagship at the time was the Mercedes-Benz Type Type 300 (W186), which was introduced by Mercedes in 1951 and was powered by a liter-to-liter inline-six engine codenamed M186 with only 115 horsepower.

Such an engine is naturally not available in civilian production models, but if it is to be put on the automobile field, it is simply weak. Rudolf Uhlenhaut, Mercedes-Benz's head of racing projects, led the team to improve the engine and increase the power by 60 hp.

However, it is still quite difficult to rely on the 175 hp engine to achieve results in the field. At that time, the cars of other manufacturers, such as Ferrari's racing car 250s, had an engine power return of 227 hp. The lack of power is one thing, and another headache for Rudolf is that the M186 engine is too large and heavy.

The Type 300's large engine compartment is not a problem to fit in, but it has to be placed on a racing car...At that time, all manufacturers were working on aerodynamics. Rudolf came up with a way to tilt the engine at 50°, which lowered the center of gravity and also lowered the height of the engine compartment. Like this:

In order to reduce the weight, Rudolf and his team developed a new body frame structure, which was built into a truss structure with pipe fittings that were welded into triangles and jointed to form a truss. The final body frame on the car weighs only 50 kilograms.

In order to ensure the stiffness of the side of the body, the threshold of the side door position is much higher than that of other cars, and the driver cannot open the door to enter normally like other cars, but needs to jump in from above. This is certainly fine on open-top cars.

But when it comes to participating in some rallies such as the 24 Hours of Le Mans, the body must be closed. At this time, the drawbacks of this construction cannot be ignored, because there is simply not enough space above the side frame for the rider to get in and out. After trying a lot of things, Rudolf decided to abandon the traditional way of opening the doors horizontally and try to put the door hinges on the roof and let the doors open up and down.

This way, the riders are able to get in and out of the way.
