[0037] The housing 1 includes a shell 11 and a shell cover 12. The upper portion of the shell 11 has an opening, and the shell cover 12 covers the opening. The shell cover 12 is detachably mounted on the shell 11 by screws, and the parts in the shell 11 can be easily inspected and maintained by removing the shell cover 12.
[0038] The battery module 2 is disposed inside the housing 11. The battery module 2 is used to provide electric energy to the lifting column 3, the driving module 4, and the control module 5 to ensure the normal operation of each component.
[0039] There are two groups of lifting columns 3, and the two groups of lifting columns 3 are correspondingly arranged on both sides of the battery module 2. The lower end of the lifting column 3 is installed on the shell 11, and the upper end of the lifting column 3 is configured to extend above the shell cover 12 or retract below the shell cover 12. When the upper end of the lifting column 3 extends above the shell cover 12, the upper end of the lifting column 3 is used to be installed in the connection hole of the material rack. Exemplarily, the lifting column 3 adopts a hydraulic lifting column or an electric lifting column. When not in use, the upper end of the lifting column 3 is retracted below the shell cover 12 to ensure a compact structure; when in use, the upper end of the lifting column 3 is used to be installed in the connection hole of the material rack so that the logistics automatic guided vehicle can drive the material rack to move for logistics transportation.
[0040] The control module 5 is arranged inside the housing 11, and is signal-connected to the lifting column 3 and the driving module 4.

[0052] like Figure 3 As shown, in some embodiments, the logistics automatic guided vehicle includes a plurality of second buffer blocks 6b, and the second buffer blocks 6b and the first buffer blocks 6a are both made of polyurethane blocks, and the second buffer blocks 6b are distributed on the periphery and the bottom of the shell 11. The arrangement of the second buffer blocks 6b and the first buffer blocks 6a ensures that the internal vibration of the logistics automatic guided vehicle will not have sharp peaks during normal operation, and the amplitude of the vibration is reduced. Among them, the first buffer block 6a mitigates the impact of the sudden force generated by the vibration on the drive module 4, and the second buffer block 6b avoids the impact of the whole machine resonance on the machine body, and also reduces the noise of the normal operation of the machine body.
[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention.
