Description

Technical Field

[0001] The utility model relates to the field of bus boarding and alighting assisting devices, in particular to a barrier-free boarding and alighting assisting device. Background Art

[0002] A bus alighting platform is a special device designed to facilitate the disembarkation of passengers, especially those with limited mobility (such as wheelchair users). The primary purpose of a bus alighting platform is to facilitate barrier-free boarding and alighting, making it more convenient and safe for passengers with limited mobility to travel on buses. This design allows buses to better serve passengers with disabilities, the elderly, and other special needs.

[0003] In the existing technology, a wheelchair is located at the rear door of the vehicle and can be opened manually. The movable board can be placed on the ground or directly on the platform where there is a bus stop. The bus and the platform are basically level, and the movable board has almost no angle, allowing disabled people to wheel their wheelchairs onto the bus. However, this requires the driver to actively fold the board, and then the disabled person must wheel their wheelchair onto the bus. Because the board is inclined, manually climbing up is very strenuous and requires someone to push and support from behind. There is even the possibility that the wheelchair will roll back, causing injuries to people behind or the person in the wheelchair. There is also the possibility that the wheelchair will accelerate due to inertia when getting off the bus, causing injury to others or the person in the wheelchair.

[0004] Therefore, a barrier-free on-and-off assist device is designed to slow down the speed of the wheelchair getting off the vehicle, prevent the vehicle from sliding back, and assist the wheelchair in getting on and off the vehicle. Utility Model Content

The movement of the movable plate A302 drives the movable plate B306 to move together, completing the up and down opening and closing of the armrest 301.

[0041] The roller device 5 is arranged in the middle part of the upper and lower car plates 2, and side baffles 502 are arranged on both sides of the roller device 5. Several rollers 501 are arranged between the side baffles 502. A motor 503 and a reducer 504 are arranged on the side baffle 502 on one side. A rotating shaft extends from the reducer 504 and passes through the side baffle 502. A driving sprocket 505 is arranged on the rotating shaft, and a chain 507 is arranged on the driving sprocket 505. At the same time, a chain limiting plate 508 is arranged on the side of the driving sprocket 505. There are movable cavities above and below the chain limiting plate 508. The overall appearance is I-shaped. A driven sprocket is arranged on the inner wall of the side baffle at the end point of the chain limiting plate 508. The chain 507 passes through the cavity on the chain limiting plate 508. The chain 507 passes through the driven sprocket and then through the lower cavity of the chain limit plate 508 to return to the driving sprocket 505 to complete the arrangement of the entire chain 507; a sprocket 509 is provided on the upper side of the chain limit plate 508, and the sprocket 509 is fixedly connected to the fixed block 510 by bolts. A rotating rod 506 is provided in the middle of the fixed block 510, and the roller 501 is connected and fixed to the fixed block 510. At the same time, the rotating rod 506 passes through the roller 501, and the rotating rod 506 is mounted on the side baffle 502. The sprocket 509 on the rotating rod 506 is engaged with the chain 507 on the upper side of the chain limit plate 508. The movement of the chain 507 drives the sprocket 509 to rotate, thereby driving the roller 501 to rotate. When the wheelchair 18 touches the roller 501, it drives the wheelchair 18 to move into the vehicle.

[0042] When the front wheelchair 18 is in the vehicle, the front wheelchair 18 is in the vehicle door opening and the rear wheelchair 18 is in the vehicle door opening.

[0043] Working principle: When someone in a wheelchair needs to get on the vehicle, the driver starts the assisted boarding function. First, the car will play a rising sound to remind pedestrians inside and outside the vehicle to be careful. After the movable panel under the door is opened, the telescopic rod 8 starts to extend and pushes the rotating device 7 to move outward. When the limit block at the bottom of the boarding and disembarking plate 2 slides to the end of the limit groove 6 of the lower bottom plate 1, the entire boarding and disembarking plate 2 is opened. At this time, the rotating device 7 starts to rotate the boarding and disembarking plate 2 downward to the ground or platform to complete the installation of the boarding and disembarking plate 2; at this time, the control center controls the armrest device 3 to start the folded armrest 301 to unfold, the roller device 5 starts the roller 501 to start rotating slowly, and the hand-cranked wheelchair 18 wheels shake the front wheels onto the roller 501 Because the roller 501 provides an upward force when it rotates slowly, the person in the wheelchair can move into the car door with less effort. At the same time, the person can hold the handrails on both sides to maintain stability, or pull the handrails 301 with their hands to provide pulling force to move into the car door. When the wheelchair passes the opening and closing baffle 4, the baffle 4 feels the pressure, and the movable rod also feels the pressure and retracts and closes to allow the wheels to pass. When the rear wheel completely passes the rear baffle 4, it opens here to prevent the wheelchair from sliding down and causing an accident. When the wheelchair is completely on the car, the driver turns off the boarding assistance, the roller device 5 stops rotating, the handrail 301 is folded and retracted, the rotating device 7 returns the upper and lower car plates 2 to the normal position, the baffle 4 is closed, and the telescopic rod 8 retracts the entire upper and lower car plates 2.

[0044] When it is necessary to get off the vehicle, the driver turns on the assisted getting off function and first makes a sound to remind pedestrians inside and outside the vehicle to be careful, then opens the boarding and exiting platform 2. After opening, the boarding and exiting platform 2 opens the folding armrest 301. At this time, the baffle 4 on the boarding and exiting platform 2 is not opened, and the roller device 5 no longer rotates. The entire roller device 5 acts as a speed bump to slow down the wheelchair when getting off the vehicle. At the same time, people can also grab the armrest 301 to stabilize themselves, so that the wheelchair 18 can land safely.

[0045] The entire auxiliary up and down device is controlled by the vehicle's control center, and the power supply required internally is connected to the vehicle's power supply.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive.
