Barrier-free bus door

Abstract

The invention relates to the related field of automobile electronic control, in particular to a barrier-free bus door which comprises a bus body, a bus door cavity penetrating front and back is formed in the bus body, upper shafts are fixedly arranged on the top wall of the bus door cavity in a bilateral symmetry mode, and upper connecting rods extending left and right are rotatably arranged on the outer surfaces of the upper shafts. The gear is driven by the pull wire and the torsion spring to rotate, so that the gear moves on the rack, the first-order transverse bridge is stretched, meanwhile, the gear and the rack are meshed through the push rod, the second-order transverse bridge is stretched, and meanwhile, in order to cooperate with stretching of the second-order transverse bridge, the stretching length of the pull wire is kept unchanged, and a motor needs to be electronically controlled to rotate forwards and reversely, so that the first-order transverse plate is enabled to extend and retract along with the second-order transverse plate after linear extension and retraction. And meanwhile, by abutting against the bus station, the rack is pushed to enable the gear to rotate by 90 degrees, and therefore the supporting frame rotates by 90 degrees to abut against the ground.

Description

technical field [0001] The invention relates to the related field of automobile electronic control, in particular to a barrier-free bus door. Background technique [0002] At present, the bus stops are all higher than the ground, but the height is relatively small. In the face of rainy days, there is often water in front of the bus stops. When the bus stops or other vehicles pass by, it will splash water, which will cause inconvenience to people in the bus station. , In addition, there are often many people crowded in front of the bus stop in order to enter the bus ahead of time. Such behaviors are very dangerous. The difficulty of bus has also improved the difficulty of bus driver's stop at bus station, for solving the problem of bus stop difficulty and passenger getting on and off bus difficulty, it is necessary to arrange a kind of barrier-free bus door. Contents of the invention [0003] The object of the present invention is to provide a barrier-free bus door, which ...

[0002] At present, the bus stops are all higher than the ground, but the height is relatively small. In the face of rainy days, there is often water in front of the bus stops. When the bus stops or other vehicles pass by, it will splash water, which will cause inconvenience to people in the bus station. , In addition, there are often many people crowded in front of the bus stop in order to enter the bus ahead of time. Such behaviors are very dangerous. The difficulty of the bus also increases the difficulty of the bus driver to stop at the bus station. In order to solve the problems of the difficulty of stopping the bus and the difficulty of passengers getting on and off the bus, it is necessary to set up a barrier-free bus door.
