[0002] With the rapid economic take-off, the subway has become the first choice of transportation for many office workers due to its fast and convenient characteristics.

[0003] In the current rapid urbanization process, people's work and life rhythms are accelerating, and the work forms are becoming increasingly diversified and liberalized. Nowadays, people's demands for working anytime, anywhere, temporarily, freely, and urgently are continuously increasing. In addition, as the radiation range of the subway network in each city continues to expand, the travel distance and travel time of passengers on the subway are also increasing. Therefore, in the subway carriage, the phenomenon of carrying a bracket to place a computer or tablet for work is gradually increasing, and even people will stand and work in a standing-room-only situation. On the one hand, this phenomenon reflects the urgent need for people to work temporarily in the subway carriage, and on the other hand, it also exposes the potential safety hazards in the subway carriage. Especially for passengers standing and working, due to poor stability and crowded carriages, they are extremely vulnerable to personal injuries and pose potential traffic accident hazards. Moreover, with the continuous development of society and the continuous progress of technology, it will gradually become a daily routine for people to use the in-transit time on the subway to work in the carriage.

[0004] In addition, the advent of mobile phones has profoundly changed people's living patterns. Thanks to the rapid development and wide popularity of smartphones such as iOS and Android, people have developed a certain dependence on mobile phones. In the subway environment, there is a common phenomenon: most passengers use mobile phones as entertainment tools. However, since the mobile phone needs to be held in the hand and viewed with the head down in front of the chest, it is easy to cause neck soreness over time, and even may lead to cervical spondylosis, dizziness, and even vomiting symptoms in the long run. This will become a serious modern social disease and must be highly vigilant and alleviating measures should be taken. At the same time, with the development of network technology and the popularization of 5G, the demand for mobile phone charging has increased sharply.
