Description

Technical Field

[0001] The utility model relates to the technical field of cab assembly peripheral parts, in particular to a multifunctional off-road vehicle boarding step and a combined boarding ladder. Background Art

[0002] At present, due to structural reasons, off-road vehicles have many parts that cannot be directly approached, or when personnel perform tasks in the field, they will encounter horizontal or vertical obstacles and need to use special boarding ladders to complete the tasks. This requires off-road vehicles to carry special boarding ladders. Therefore, off-road vehicles need to leave appropriate space for storing boarding ladders. For easy access, they are generally located outside the vehicle body, which will reduce the passenger space and is not conducive to driving safety. However, when the size of the entire vehicle is determined, designing a special boarding ladder storage space will reduce the available space of other structures of the off-road vehicle and even affect the performance of some parts. An unreasonable storage position may even affect the vehicle's passability and safety.

[0003] During the vehicle design phase, in order to facilitate passengers getting on and off the vehicle, the lowest ground clearance of the boarding ladder set for off-road vehicles is required to be as low as possible in the design value. At the same time, in order to ensure the passability of off-road vehicles, the minimum ground clearance of off-road vehicles is required to be as large as possible. There is a contradiction between these two indicators. At present, the design is usually based on ensuring the passability of the vehicle. However, once the height of the boarding step is too high, it is inconvenient for passengers to get on and off the vehicle. The existing boarding ladders cannot meet the requirements of taking into account both the passengers getting on and off the vehicle and the passability and safety of the vehicle.
