Problems solved by technology

During the working process of the flip-type tail lift, the entire plane of the working panel is in an inclined state, and the inclination angle is generally between 6° and 9°. It is difficult or laborious to load and unload goods with manual or hydraulic trucks, especially when the goods are heavy.
The vertically extendable and low-hanging tail lifts avoid the defect that the tail lift forms a certain angle with the ground. After the tail lift touches the ground, the height of the working panel from the ground is low and can always be kept horizontal. However, these two tail lifts mainly realize the The lifting movement between the ground and the ground is mainly aimed at the situation of moving goods from the ground to the car compartment. The scope of application is limited and the flexibility is poor.

Abstract

The invention provides a multi-level lifting type tail plate device of a logistic vehicle, which comprises a tail plate and two tail plate driving devices. The tail plate driving devices are respectively arranged on two sides of the tail plate, each tail plate driving device consists of a guide rail, a primary slider, secondary sliders, lifting driving devices and retractable traction rods, the guide rails are arranged on side boards of a carriage of the automobile, the primary sliders are disposed on the guide rails and can ascend and descend along the guide rails, the secondary sliders are arranged on the primary sliders and can ascend and descend on the primary sliders, bottoms of the secondary sliders are connected with the bottom of the tail plate in a hinged manner, the lifting driving devices are arranged on the primary sliders, drive the primary sliders to ascend and descend along the guide rails, ascend and descend along with the primary sliders and further drive the secondary sliders to ascend and descend along the primary sliders, one end of each retractable traction rod is hinged on the corresponding secondary slider, and the other end of each retractable traction rod is hinged on the tail plate and drives the tail plate to be unfolded and flatly placed or folded and closed relative to the corresponding secondary sliders. The multi-level lifting type tail plate device of the logistic automobile has the advantages that multi-level lifting of the tail plate of the automobile is realized by the aid of expansion and contraction movement of a two-level slider structure, and a lifting range of the tail plate is expanded.

Description

technical field [0001] The invention relates to a vehicle handling equipment, in particular to a logistics vehicle tail plate device. Background technique [0002] The car tailgate is a hydraulic lifting and unloading equipment that is installed at the rear of ordinary trucks or various closed trucks and powered by on-board batteries. It can greatly improve the efficiency of vehicle transportation and loading and unloading, and has become one of the necessary equipment for modern cargo transportation vehicles. my country has introduced automobile tailgates since the early 1990s, and it is still in its infancy, and most companies are still imitating mature products from Europe and the United States. [0003] At present, there are mainly three types of tailgates on the market: flip-type tailgates, vertical lift-type tailgates and low-rise tailgates. During the working process of the flip-type tail lift, the entire plane of the working panel is in an inclined state, and the i...
