Vehicle-mounted electric telescopic platform

Abstract

The invention discloses a vehicle-mounted electric telescopic platform, which comprises a movable platform, a foldable boarding ladder, an electric reducing mechanism and lead screw transmission mechanisms. The movable platform is connected with the rear end of a frame through high-strength three-stage guide rails on the two sides. The foldable boarding ladder is arranged in one side of the movable platform. The electric reducing mechanism is arranged in the rear end of the frame. The lead screw transmission mechanisms are arranged in parallel on the two sides of the movable platform. The power output end of the motor reducing gear combination of the electric reducing mechanism is connected with the middle part of a transmission shaft. The two ends of the transmission shaft are respectively connected with the lead screw transmission mechanisms through the input end of a power steering transmission case and the output end of the power steering transmission case. The vehicle-mounted electric telescopic platform has the advantages that the structure is compact; the platform is convenient to use; since an electric transmission mechanism is used, the unfolding and the folding of the movable platform can be quickly realized. After the movable platform is unfolded, the foldable boarding ladder is drawn out, a wide, large and safe boarding platform is provided for people who want to board a vehicle, and the people who want to board the vehicle can also conveniently and quickly board the vehicle.

Description

technical field [0001] The invention relates to a boarding platform for a vehicle, in particular to a telescopic platform installed at the rear end of a vehicle, which can be electrically extended and expanded, and can accommodate a foldable boarding ladder, and belongs to the technical field of auto parts. Background technique [0002] With the continuous increase of the types of special vehicles, the requirements for special vehicle boarding tools are also constantly increasing. The existing special vehicle boarding tools mainly have the following two forms: 1. External boarding ladder, 2. Stand alone at one end of the vehicle Set up boarding platforms and boarding steps. The first form needs to be temporarily hooked to the external-mounted boarding ladder during use for the use of passengers. Because the vehicle space is small and the size of the ladder is small, it is difficult for passengers to get on and off the car to achieve a comfortable effect. The boarding platfo...
