Description
Technical Field
The utility model relates to the technical field of vehicles, in particular to a large-sized vehicle wheelchair guide plate.
Background
At present, large vehicles such as buses, midbus buses, buses and the like generally adopt a manual wheelchair guide plate for getting on and off a wheelchair when a disabled person gets on and off the wheelchair. The structure is simpler, but the operation is very inconvenient, and a driver needs to leave a driving seat to manually open a wheelchair guide plate to be put between the ground of a carriage and the ground of a road when the driver gets on or off a bus in a riding way every time, so that the wheelchair can get on or off the bus conveniently; after the handicapped gets on the bus, the guide plate is manually closed, which is time-consuming and labor-consuming, and is not suitable for the development direction of the new energy bus with high efficiency and intelligence.
Chinese patent No. CN215425612U discloses a telescopic wheelchair guide plate suitable for mounting on two-step high-pedal bus passenger vehicles with upper and lower doors, and for facilitating the handicapped to get on and off the wheelchair. When the pneumatic switch is opened, a driver opens the pneumatic switch through the cab. The first air cylinder pushes the guide plate bin to prop up, the second air cylinder in the guide plate bin pushes the second telescopic guide plate on the guide rail to slide out of the guide plate bin, and the second telescopic guide plate pushes the third guide plate connected with the hinge to extend out of the step pedal of the upper and lower vehicle doors. The two steps (carriage floor) and the first guide plate, the second telescopic guide plate and the third guide plate form a ramp with the ground. The wheelchair and the wheel type push-pull cart can be conveniently used for getting on or off the disabled. When the guide plate is retracted, a driver turns off the pneumatic switch, the second push rod of the air cylinder contracts and pulls the second telescopic guide plate to enter the guide plate bin, the second telescopic guide plate pulls the third guide plate, and meanwhile the first air cylinder also pulls the guide plate bin, and the side of the guide plate bin is arranged beside the step side plate. The guide plate is arranged on the step at one step in a three-level way, so that passengers can conveniently get on and off the vehicle door. However, when the wheelchair guide plate is used, more air cylinders are used, the cost of the air cylinders is high, and the manufacturing cost of the vehicle is increased intangibly.

Detailed Description
The technical scheme protected by the utility model is specifically described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, a wheelchair guide for a large vehicle includes: the guide plate 1 and the fixed plate 2 are connected through the hinge, the connecting rod assembly 3 is arranged between the guide plate 1 and the fixed plate 2, and the folding and unfolding states of the guide plate 1 and the fixed plate 2 are realized through the connecting rod assembly 3, so that when the wheelchair is required to be used, the guide plate 1 is unfolded outwards and is inclined downwards to be contacted with the ground, and the wheelchair can get on or off conveniently.
The connecting rod assembly includes: the first connecting rod 31 is rotatably connected to the guide plate 1 through the first pin shaft 33, the second connecting rod 32 is fixedly connected to the driving component 4 at the fixed plate 2, the first connecting rod 31 and the second connecting rod 32 are rotatably connected through the second pin shaft 34, the driving component 4 drives the second connecting rod 32 to rotate along the transmission shaft 44 of the driving component 4, and when the second connecting rod 32 rotates, the first connecting rod 31 can be pulled by the second connecting rod 32 and the angle between the first connecting rod 31 and the second connecting rod 32 is changed due to the fact that the first connecting rod 31 and the second connecting rod 32 are connected through the rotatable second pin shaft 34, so that the guide plate 1 can be folded and unfolded.
As shown in fig. 3, 4 and 5, the driving assembly 4 includes: the transmission shaft 44 and the connecting block 46 for connecting the transmission shaft 44 and the second connecting rod 32, one end of the transmission shaft 44 is inserted into the second connecting rod 32, and the joint surface of the transmission shaft 44 and the second connecting rod 32 is of a non-circular arc structure, so that the connection between the transmission shaft 33 and the second connecting rod 32 is fixedly connected, when the transmission shaft 33 rotates, the second connecting rod 32 rotates by taking the transmission shaft as a circle, the connection part of the transmission shaft 33 and the second connecting rod 32 is fixed through the connecting block 46, and the connection stability of the transmission shaft 33 and the second connecting rod 32 is improved.
As can be seen in fig. 3, the drive shaft is driven by a motor 41, a speed reducer 42, through an electronic clutch 43. The main shaft of motor 41 connects speed reducer 42, and the output of speed reducer 42 passes through the gear connection in electronic clutch 43, and transmission shaft 44 passes the axle center of electronic clutch 43 and rotates along with electronic clutch 43, through the setting of speed reducer 42, can reduce the rotational speed of motor 41 to reduce the running speed of transmission shaft 44, the use of electronic clutch 43 has realized the rotation and the stop of transmission shaft 44.
In other embodiments, after the spindle of the motor 41 is connected to the speed reducer 42, the output end of the speed reducer 42 may also be directly connected to the electronic clutch 43, and the electronic clutch 43 drives the transmission shaft 44 to rotate, so as to achieve the purposes of saving cost and smooth rotation.
