Problems solved by technology

[0002] In existing forklifts, the steering angle of the steering axle is up to 172°. The steering axle of this structure is bulky and flexible, with large resistance and poor load-bearing capacity. In addition, it is generally hydraulically driven with a horizontal oil cylinder structure, resulting in no way for the steering accuracy of the steering axle. Precise control, forklifts can only be operated by manual driving, and cannot be used in automatic unmanned driving mode. With the development of industrialization, there is an increasing demand for unmanned and autonomous forklifts, so it is necessary to improve

Embodiment Construction

[0021] Attached below Figure 1-4 One embodiment of the present invention is described.

[0022] The unmanned electric forklift has a vehicle body 3 and a battery 1 arranged on the vehicle body 3. A plurality of peripheral obstacle safety monitoring devices 21 are arranged on the outer edge of the vehicle body 3. When obstacles appear around the vehicle and enter the dangerous area At this time, the peripheral obstacle safety monitoring device 21 works and sends out a signal to make the vehicle automatically decelerate and take actions such as detour or emergency braking, so as to avoid safety accidents. The vehicle body 3 is also provided with a battery quick charging device 22. When the electric energy of the battery 1 reaches the warning limit, the vehicle will automatically run to the charging station and start the charger. The battery quick charging device 22 works to automatically charge the battery 1 to meet the Vehicle usage requirements. The vehicle body 3 is provid...

Abstract

The invention provides an unmanned-driving electric forklift, which is provided with a forklift body and a storage battery, wherein the storage battery is arranged on the forklift body, the forklift body is provided with a working device, the lower end of the front part of the forklift body is provided with a left driving wheel and a right driving wheel, the left driving wheel is controlled by a left driving motor and a left transmission to drive, the right driving wheel is controlled by a right driving motor and a right transmission to drive, the lower end of the back part of the forklift body is provided with a steering bridge device with 180-degrees steering, the forklift body is provided with a forklift general control device for controlling the single forklift to run and for controlling a plurality of forklifts to synchronously run, and meanwhile, the interior of a driving cab of the forklift body is provided with a mode switch device which is used for switching an automatic operation mode and a manual operation mode. The electric forklift has the advantages that the storage battery is adopted as power, the operation method adopts a forklift automatic unmanned-driving mode and a manual driving mode, and the safe and instant switching of the two modes is realized; the labor source is saved, and the manual false rate is reduced; and the forklift is provided with a reliable safe protection alarm device, so the accidents are avoided.

Description

technical field [0001] The invention belongs to the technical field of electric forklifts, and in particular relates to an unmanned electric forklift. Background technique [0002] In the existing forklift, the maximum steering angle of the steering axle is 172°. The steering axle of this structure is cumbersome and flexible in steering, has large resistance, and has poor load-bearing capacity, and is generally hydraulically driven by a horizontal cylinder structure, which leads to the inability of the steering precision of the steering axle. Precise control, forklifts can only be operated by manual driving, not autonomous and unmanned. With the development of industrialization, there is an increasing demand for unmanned and autonomous forklifts, so it is necessary to improve. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an unmanned electric forklift that can be driven manually, and can also be driven automatic...
