Problems solved by technology
[0002] Buses have been popularized in large numbers in cities. Due to the uneven distribution of urban passenger flow in the process of bus operation, it will inevitably lead to serious congestion of people in buses. Through field investigations, it is found that most of the congestion in buses is not simply Due to the large number of people, passengers chose the front station due to the instinctive convenience in the process of choosing the station, which made the bus boarding place extremely concentrated, while the back section was relatively sparsely populated. During the process, the people in the front section of the bus body will become more and more concentrated and eventually lead to serious congestion. However, through experiments, it has been found that as long as the position of the pull ring in the bus is adjusted, the people who get on the bus at the beginning will choose the place with the pull ring. If the position of the pull ring is reasonable, the people who initially get on the bus can be dispersed, thereby alleviating the congestion phenomenon. The purpose of the present invention is to design a structure that can adjust the position of the pull ring to achieve adjustment through the pull ring to slow down the congestion of people. question

A pull ring structure of an electric car comprises an ejector rod. A rack is arranged on the ejector rod. A lantern ring is connected to the outer side of the ejector rod in a sleeving mode. A driving gear engaged with the rack is arranged on the lantern ring, connected with a stepping motor through a reduction gearbox and driven by the stepping motor. A power source box used for providing power for the stepping motor is arranged on the lantern ring. A pull ring is arranged at the lower end of the lantern ring. The pull ring structure has the advantage of adjusting the person position by adjusting the position of the pull ring relative to the ejector rod.
