Compared with the traditional car navigation, mobile navigation has stronger logic and operation experience, and at the same time, the map is updated quickly, without annual fee, convenient and portable, and has a high degree of intelligence. However, it is a mobile phone after all. In the actual navigation process, the limited screen size has become the biggest obstacle in navigation.
Matters needing attention in vehicle navigation
Attention should be paid to the shutdown sequence of car navigation after use: first close the page, then turn it off, and finally unplug the power. Some car owners have convenient maps, so they can unplug them directly after use and never turn off their mobile phones. This saves trouble, but it is easy to damage electronic components after a long time. In addition, it is best to charge the machine three times before use, each time about 10 hour, so as to maximize the storage capacity of the battery. Start the car first and then plug in the cigarette lighter.
Although there are many kinds of vehicles, their structures are similar. This should be said to be the credit of standardization and the need of large-scale production line. With the development of society, the progress of science and technology and the change of demand, the appearance of railway vehicles has also begun to change, especially the passenger cars are no longer the same old faces. However, their basic structure has not changed obviously, but the specific parts have more scientific and advanced structural design.
Generally speaking, the basic structure of a vehicle consists of five parts: body, underframe, running gear, coupler buffer device and braking device.
The car body is the part of the vehicle carrying goods or passengers, and it is also the basis for installing and connecting other parts of the vehicle. The bodies of early vehicles were mostly wooden structures, supplemented by steel plates and bow bars. Modern automobile body is mainly steel structure or light metal structure.
