Description

Technical Field

[0001] The utility model relates to the technical field of electric transport vehicles, in particular to a cargo supporting structure of an electric transport vehicle. Background Art

[0002] A pallet truck is a logistics handling equipment used to transport goods. When a manual pallet truck is used at a handling station, the fork it carries is inserted into the hole of the pallet, and the hydraulic system is driven by manpower to lift and lower the pallet goods, and the handling operation is completed by manpower pulling. It is the simplest, most effective and most common loading and unloading and handling tool among the pallet transportation tools at the handling station. Electric trucks include fully electric trucks represented by electric forklifts and automatic unmanned trucks equipped with system centralized control and management computers.

[0003] Unmanned guided vehicles are increasingly being used in the logistics industry. The main guidance methods for unmanned guided vehicles include electromagnetic induction guidance, laser guidance, and magnet gyro guidance. However, unmanned guided vehicles generally use a platform with a liftable upper surface as the basic structure for supporting items. When unmanned guided vehicles carry items, during the process of starting, stopping, and turning, the goods are mainly kept stable by the friction between themselves and the platform, so there is a risk of falling. However, if railings are set around the platform, the volume of goods transported by the transporter will be limited, which is not conducive to use. Utility Model Content
