The history of cars
First,1885+In June 2000, German Carl Benz (1844 ~ 1929) successfully developed the world's first car, which laid the foundation for car design in one fell swoop, and even today's cars can't jump out of this box.
2. On 1886129 October, he applied to the German Patent Office for an automobile invention patent, and in the same year12 October, the Patent Office officially approved it 165438. Therefore,1886 65438+1October 29th is recognized as the birth date of the world automobile, and Ben Ci's patent certificate has also become the first automobile patent certificate in the world.
Thirdly, in fact, before Ben Ci, some people were already developing car engines and cars. French newspapers reported that Renault invented this car as early as 1863, and its speed was less than 8km /h, but it still ran 18km from Paris to Joveriboda. 1884, a Frenchman, Debo Thivel, made a three-wheeled car with a single-cylinder internal combustion engine and a four-wheeled car with a double-cylinder internal combustion engine with the internal combustion engine as the power source.
Four, as early as before the invention of the first car, there have been many related inventions, such as lead-acid batteries, internal combustion engine ignition devices, hard rubber solid tires, spring suspensions and so on. So the car is a comprehensive application of many inventions or technologies.

Automobile cold knowledge
1, the origin of the name "car"
Let me start with the origin of the English name "Sedan". The word "car" existed long before the invention of the automobile, referring to the luxury carriage used by European nobles. It is not only well decorated, but also closed, which can prevent wind, rain and dust and improve safety. /kloc-After it was introduced to the United States in the 0/8th century, only the rich in a few big cities such as new york and Philadelphia were eligible to enjoy it.
When Ford, the American automobile king, introduced Model T in 1908, the car changed from open to closed, and the comfort and safety were greatly improved, which was a great progress at that time. Ford wanted to highlight his great progress in sales promotion, so he had a brainwave and called his "closed car" a "car", giving car buyers a psychological satisfaction.
Let me start with the origin of China people's names. In fact, there was the word "car" in ancient China, referring to the sedan chair pulled by mules and horses. When a large number of western cars entered China, it was the time when closed square cars were popular in the West. At that time, the appearance of the car was as splendid as the sedan chair in ancient China. Therefore, people called cars at that time "cars".
2. The design life of airbag is only 8- 10 years.
For many car owners, airbags must have been heard a lot, but they are rarely used. But in daily driving, airbags can not be ignored. Don't find that the airbag can't be opened when it is really needed, and don't pop up when it is completely unnecessary.
Many car owners know the function of airbags, but they don't know its design service life, but many car owners will scrap their vehicles without replacing airbags. Theoretically, the design life of automobile airbag is consistent with the service life of the whole vehicle.
However, due to the lack of design standards, the actual life of airbags is not that long. Although there is no clear shelf life, the quality of the airbag is difficult to guarantee even if it is not detonated after 8 to 10 years of use. After the vehicle travels10,000 to 20,000 kilometers, you should go to the 4S shop to check the airbag and its accessories.
