Pedaling ladder device and vehicle thereof

Abstract

The invention belongs to the technical field of vehicles, and discloses a pedaling ladder device and a vehicle thereof. The pedaling ladder device comprises a pedaling ladder mechanism, a fixing mechanism, and a folding mechanism, wherein the fixing mechanism is connected to a frame; the folding mechanism comprises a first rotating rod, a second rotating rod and an elastic piece; the two ends of the elastic piece are connected to the first rotating rod and the second rotating rod correspondingly; the elastic piece is always in a stretched state; one end of the first rotating rod is rotationally connected to the fixing mechanism, and the other end of the first rotating rod is rotationally connected to the pedaling ladder mechanism; one end of the second rotating rod is rotationally connected to the fixing mechanism, and the other end of the second rotating rod is rotationally connected to a pedaling ladder mechanism; a quadrilateral structure is formed among the first rotating rod, thesecond rotating rod, the pedaling ladder mechanism and the fixing mechanism; and the pedaling ladder mechanism is configured to turn over relative to the fixing mechanism, so that the pedaling laddermechanism is switched between a folded state and an unfolded state. The pedaling ladder device has damping and decelerating effects in the folding process and is good in use comfort.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a pedal ladder device and a vehicle. Background technique [0002] At present, the existing pedal ladder devices for commercial vehicles are generally divided into fixed structure and folding structure. The pedal ladder device adopts a folding structure, which is prone to impact events caused by excessive force during the folding process. feeling poor. The pedaling ladder device adopts a fixed structure and is fixedly connected to the frame or other support structures, and the position cannot be moved, and has the following defects: [0003] 1. The traditional fixed pedal ladder device occupies a limited layout space outside the frame, and its use frequency is not high, so that the space utilization rate it occupies is not high; [0004] 2. The traditional fixed pedal ladder device is generally arranged on the lateral outer side of the vehicle frame, and the usual use rate is ...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional fixed pedal ladder device occupies a limited layout space outside the frame, and its use frequency is not high, so that the space utilization rate it occupies is not high;

[0004] 2. The traditional fixed pedal ladder device is generally arranged on the lateral outer side of the vehicle frame, and the usual use rate is low, but it occupies the lateral layout space of the vehicle, making it more difficult to arrange the lateral space of the vehicle with little margin;

[0005] 3. The traditional fixed pedaling ladder device is generally suspended on the outside of the frame with a cantilever beam structure. During the driving process, the pedaling ladder device is useless, but it will become the dynamic load of the frame and increase the load burden of the frame;

[0006] 4. If the traditional fixed pedaling ladder device is fixed on the outside of the post processor or the battery box, the pedaling ladder device forms a structure similar to a "guardrail", which reduces the maintenance accessibility of the systems and components inside it. Poor, when the user wants to repair the parts on the inner side of the pedal ladder, he needs to bypass the pedal ladder or remove it together, which increases the difficulty and cost of maintenance
