Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1-4, this embodiment provides a remote control electric full transfer vehicle, including an omnidirectional mobile chassis 1, a lifting platform 2, a comprehensive control box 3, an emergency stop button 4, a sound and light alarm 5 and a receiving antenna 6. The frame 1-1 is provided with a accommodating space for accommodating a lifting platform 2 and a comprehensive control box. The lifting platform 2 is driven by a screw electric lifting mechanism, and the screw electric lifting mechanism and the omnidirectional mobile chassis pass through the comprehensive control box 3. control.

As shown in Figure 5, the omnidirectional mobile chassis is composed of a frame 1-1, a Mecanum wheel 1-2, a suspension module 1-3, and a drive shaft system. The chassis frame adopts a high-strength steel integrated welded frame to carry the load of the whole vehicle; the Mecanum wheel is composed of aluminum alloy supporting hubs and high-strength polyurethane rollers; the suspension module adopts the form of hydraulic independent suspension to ensure the stability of the vehicle; drive The shaft system adopts servo drive motor 1-4 and high-precision reducer 1-5. The high-precision control of the motor is realized through the Can bus, which ensures the synchronization of the four drive shaft systems, prevents the stall between the wheel sets, and realizes the speed of the servo motor. Efficient delivery. The omnidirectional mobile chassis used in the present invention adopts the existing known technology.

In this embodiment, as shown in FIG. 6 , the lifting platform 2 includes a lower base 2-2 and an upper base 2-1, the lower base 2-2 is fixed in the frame accommodating space, and the lower base 2-2 passes through The fork frame 2-4 is connected with the upper base 2-1, and the upper base 2-1 is connected with the screw electric lift mechanism 2-3, and the screw electric lift mechanism 2-3 drives the upper base 2-1 to move up and down relative to the lower base.
