Description

Subway entry and exit transfer car for disabled wheelchairs

technical field

The invention belongs to a means of transportation, in particular to a transfer vehicle for wheelchairs entering and leaving a subway station.

Background technique

With the rapid development of my country's economy, the penetration rate of urban subways in my country is also getting higher and higher. As an ordinary citizen, the main means of transportation in the city still relies on the subway. It has become a natural obstacle, which requires the disabled to rely on the help of their family members to travel. For this disabled person, sitting in a hand-push wheelchair, it is very inconvenient to enter and exit the subway station. People carry a rolling elevator on their backs and then sit in a wheelchair; either they spend a lot of money to buy a stair-climbing wheelchair that can climb stairs, and then they can go up and down the stairs normally; but not everyone has the money to buy a stair-climbing wheelchair. For the poor, they can only go up and down. If you choose not to go out, go out less, or let others carry it on your back. In view of the above situation, we have developed a small subway entry and exit transfer vehicle for disabled wheelchairs, which is low in cost, simple in operation, safe and reliable, and suitable for public use.
