[0039] The driving module with the above structure includes a driving component and a hydraulic cylinder 2 arranged on the installation base 1, a slewing component 4 connected to the hydraulic cylinder 2, and a buffer component 5 arranged on the slewing component 4. Among them, the driving component and the hydraulic cylinder 2 avoid each other to prevent interference between the driving component and the hydraulic cylinder 2. The slewing component 4 specifically includes a slewing bearing 41 and a first mounting member 42. In this embodiment, the first mounting member 42 is a first mounting plate. One side of the first mounting member 42 is connected to the piston rod of the hydraulic cylinder 2, and the other side of the first mounting member 42 is connected to the slewing bearing 41. The slewing bearing 41 can be connected to the vehicle body of the AGV. Thus, driven by the piston rod of the hydraulic cylinder 2, the first mounting member 42 can drive the slewing bearing 41 to move in the vertical direction, and further enable the slewing bearing 41 to drive the vehicle body of the AGV to move in the vertical direction, and enable the AGV to carry materials placed at different heights.

One side of the buffer unit 51 arranged in the mounting portion is connected to the first mounting member 42, and the other side is abutted against the lifting member 52.

In addition, the buffer unit 51 has an elastic force, which is generated when the elastic member 511 is compressed by the mutual approach of the slewing assembly 4 and the lifting member 52. Since the slewing support 41 is always subjected to the gravity of the AGV vehicle body, the slewing assembly 4 always has a tendency to approach the lifting member 52, and thus the elastic member 511 always has an elastic force.

Each second guiding member 621 passes through a second guiding seat 622 and is connected to the lifting member 52. Thus, when the lifting member 52 moves in the vertical direction, each second guiding member 621 can slide on the first guiding seat 612, and further guide the lifting member 52.
[0050] The driving module provided in this embodiment, as Figure 1 shown, the driving assembly includes a first driving unit 31 and a second driving unit 32.

At the same time, the buffer unit 51 has an elastic force to drive the lifting member 52 to move towards the walking surface. One side of the buffer unit 51 arranged in the mounting portion is connected to the first mounting member 42, and the other side is abutted against the lifting member 52. Thus, when the driving component is not in contact with the walking surface, the elastic force of the buffer unit 51 can drive the lifting member 52 to drive the hydraulic cylinder 2 and the installation base 1 to move towards the walking surface, and further enable the driving component installed on the installation base 1 to be in contact with the walking surface, avoiding the situation that the driving module is not in contact with the walking surface when the AGV moves on the walking surface, and ensuring that the AGV can operate normally on the walking surface with uneven surface.
[0061] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
