A van truck and cargo compartment boarding device thereof

Abstract

The invention discloses a van and a cargo box boarding device thereof. The cargo box boarding device comprises a ladder climbing assembly, a ladder box assembly and a locking mechanism, wherein the ladder box assembly is installed at the bottom of a carriage of the van; the ladder climbing assembly can telescopically sleeve in a body of the ladder box assembly in the length direction; the ladder climbing assembly and the ladder box assembly are locked by the locking mechanism when being in a folding state; the ladder climbing assembly is composed of ladder climbing boundary beams arranged on the two sides, a plurality of ladder climbing steps which are fixedly connected between the two ladder climbing boundary beams and extension beams which are rotationally connected with the corresponding ladder climbing boundary beams through pin shafts; the pin shafts are arranged parallel to the ladder climbing steps; the extension beams are fixedly connected to a ladder box assembly; and the ladder climbing boundary beams swing in the vertical plane relative to the corresponding extension beams around the corresponding pin shafts and are abutted to the ground with the supporting ends when swinging to the lower limit positions. Therefore, the cargo box boarding device can safely and conveniently go up and down a cargo box, has a compacter structure and increases the space utilization ratio of a vehicle body.

Description

technical field [0001] The invention belongs to the field of vehicle engineering, and in particular relates to a cargo compartment boarding device for van trucks. The present invention also relates to a van comprising the above cargo compartment boarding device. Background technique [0002] Commercial vehicles are widely used in production and life, among which vans show an absolute advantage in the field of urban transportation. Due to the structural characteristics of van trucks, workers usually need to enter the interior of the cargo compartment when loading and unloading goods. When people enter and exit the cargo compartment, they often need to rely on external facilities, or even step on the protective device or other parts of the vehicle, causing unnecessary accidents. damage, which requires a cargo compartment boarding device to be configured on the van. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a boarding device in the...

AI Technical Summary

Problems solved by technology

[0004] like figure 1 As shown, the boarding device commonly used in the existing vans is a frame-type boarding pedal 101, which is arranged under the rear door 102 of the cargo compartment at the rear of the cargo compartment, and is fixed on the bottom of the rear door frame 103 by welding However, in this type of boarding device, the height of the pedal structure from the ground is usually 0.8m to 1m. It is extremely inconvenient for people to get on and off the cargo compartment, and it is necessary to rely on external force when loading goods. There is not too much room for lowering the height from the ground, otherwise it will block the viewing angle of the rear taillights or interfere with the rear guardrail
