Since the production of automobiles in the eighties of the eighteenth century, people have never ceased to innovate in automobiles, ranging from a screw on automobiles to a driving and launching system for automobiles. In the 1930s, car manufacturers began exploring the installation of novelty points for cars, and constantly transformed the cars. Let's take a look at the achievements they are proud of. Invention One: Magnetic Bar Cadillac, which was produced in 1957, is equipped with almost all of this magnetic bar. The four metal glasses that can hold drinks are installed in a magnetic storage box. The magnetic properties effectively prevent the drink in the glass from overflowing. Under the sensation of feeling, the noble luxury has taste and forced the explosion of the table. But was the police uncle smelled you full of wine, you can guarantee that he will not tell you to drink? Invention II: Car Recorder If you think of this kind of car jukebox as our current stereo, it would be naive. In the past, radios were generally installed on cars. It is now quite difficult to put a record player consisting of a probe and a disc on a bumpy car. At that time, in order to avoid vibration and the movement of the disc, the phono recorder's probe was designed to be pressed downwards, resulting in very easy damage to the record. If it had not been heard, the sound would have been jammed. This feeling was not very good. Invention 3: Dog Bags Directly see his own experience The design method is that the bottom of the bag is fixed on the pedal, and the upper part is hooked on the window by the hook. I can feel the dog's helpless eyes and feel the thrill of riding a roller coaster in the bag. Invention 3: Seat belts In order to allow more people to wear seat belts, in the late 1970s and early 1980s, car manufacturers fixed one end of the seat belt to the door frame. As long as the driver entered the car, the seat belt would be fastened automatically. The idea is good. In the event of a car accident, the door is knocked open and the driver is thrown out of the car. . Invention IV: Bullet Steering Wheel In order to pursue the design concept of savagely cool hanging heavens, in 1954 Cadillac invented the bullet head steering wheel, also known as the “death steering wheelâ€, which was used for braking or high-speed collision. This kind of steering wheel can directly kill the driver. Invention 5: Automatically adjust the brightness of the light system Automatically adjust the brightness of the lights, as the name implies, the brighter the outside environment is, the weaker the light is, and the darker the outside environment is, the brighter the light is. It sounded like a good idea, this time Cadillac was the first to install this automatic dimming system, followed by Buick, Pontiac, and Chevy. Not long after the problem came, the automatic adjustment system was not smart at all. In rainy or foggy days, the headlights did not shine.
