[0026] The following describes multiple preferred embodiments of the present utility model with reference to the accompanying drawings of the specification to make its technical content clearer and easier to understand. The present utility model can be embodied in many different forms of embodiments, and the protection scope of the present utility model is not limited to the embodiments mentioned in the text.

[0027] In the drawings, components with the same structure are denoted by the same numerical reference signs, and components with similar structures or functions everywhere are denoted by similar numerical reference signs. The size and thickness of each component shown in the drawings are arbitrarily shown, and the present utility model does not limit the size and thickness of each component. To make the illustration clearer, the thickness of some parts in the drawings is appropriately exaggerated.

[0028] As Figure 1 shown, the present utility model provides a load-carrying mobile robot, which includes a body 1, a driving mechanism, a carrying platform 2, a lifting mechanism, and an auxiliary mechanism;

[0029] The driving mechanism is arranged at the bottom of the body 1 and is used to drive the load-carrying mobile robot to move;

[0030] The lifting mechanism is arranged at the upper part of the body 1 and is used to lift the carrying platform 2;

[0031] The auxiliary mechanism is arranged around the carrying platform 2 and is used to assist the carrying platform 2 in carrying goods.

[0032] As Figure 2 shown, a driving cover 11 is provided at the lower part of the body 1, and the driving mechanism is arranged inside the driving cover 11.

[0033] Two sets of driving mechanisms are arranged inside the driving cover 11, and the two sets of driving mechanisms are respectively arranged at both ends of the body 1.

[0034] As Figure 2 shown, the driving mechanism includes a chassis 3, a driving component 31, and a driven component 32. The chassis 3 is arranged inside the driving cover 11, the driving component 31 is arranged on the outer side of the chassis 3, and the driven component 32 is arranged on the inner side of the chassis 3.

[0035] The chassis 3 is in a "T" shape. The driving component 31 is arranged at one end of the vertical part of the "T" shape, and the driven component 32 is arranged at both ends of the horizontal part of the "T" shape.

[0036] The driven component 32 is a universal wheel.

[0037] As Figure 2 shown, the driving mechanism further includes a cross bar 33. The cross bar 33 passes through the vertical part of the "T" shape, and both ends of the cross bar 33 are connected to the body 1.

[0038] When the load-carrying mobile robot moves, if it encounters an uneven road surface, the chassis 3 can rotate relying on the cross bar 33 to ensure that the active component 31 and the driven component 32 touch the ground simultaneously, enhancing the stability of the load-carrying mobile robot during movement.

[0039] As Figure 3 shown, the active component 31 includes a steering device 311, a driving disc 312, a driving motor 313, and driving wheels 314. The steering device 311 is arranged on the chassis 3. The driving disc 312 is fixedly arranged on the steering device 311. The driving wheels 314 are arranged on both sides of the driving disc 312. The driving motor 313 drives the driving wheels 314 to move.

[0040] As Figure 4 shown, a lifting cover 12 is provided on the upper part of the body 1, and the lifting mechanism is arranged inside the lifting cover 12.

[0041] As Figure 4 shown, the lifting mechanism includes a power source 41 and a plurality of lifting devices 42. The power source 41 is connected to the lifting devices 42 through a connecting rod 43 and drives the lifting devices 42 to work.

[0042] As Figure 4 shown, the lifting devices 42 are arranged on the body 1.

[0043] The power source 41 is a motor, and the lifting device 42 is a lead screw lifting device.

[0044] As Figure 1 and Figure 4 shown, the auxiliary mechanism includes a plurality of support columns 5. The support columns 5 are arranged around the load-bearing platform 2 on the upper part of the body 1, and the support columns 5 are higher than the load-bearing platform 2 when not working.

[0045] The support columns 5 are used to carry goods. When the load-carrying mobile robot is running, the support columns 5 carry the goods so that the goods do not contact the load-bearing platform 2.

[0046] At the initial stage when the lifting mechanism raises the load-bearing platform 2, since the goods do not contact the load-bearing platform 2, the gravity on the load-bearing platform 2 is smaller, and the pressure on the lifting device 42 is also smaller. At the final stage when the lifting mechanism lowers the load-bearing platform 2, since the goods do not contact the load-bearing platform 2, the gravity on the load-bearing platform 2 is smaller, and the pressure on the lifting device 42 is also smaller. This slows down the aging time of the lifting device and reduces the probability of damage.

[0047] When the lifting device 42 suddenly fails, the carrying platform 2 will fall directly out of control. Since the support column 5 is higher than the carrying platform 2 when it is not working, that is, the support column 5 is higher than the lowest point of the carrying platform 2, the goods will not fall directly on the carrying platform 2, but will fall on the support column 5, remaining stable without damaging the load-carrying mobile robot. At the same time, it can also prevent the goods from falling and causing damage, and prevent the goods from scattering and causing production safety accidents.

[0048] As Figure 1 shown, the load-carrying mobile robot further includes a positioning bolt 6, and the positioning bolt 6 is arranged on the carrying platform 2. The positioning bolt 6 protrudes from the carrying platform 2.

[0049] The positioning bolt 6 is used to fix the position of the goods and prevent the goods from sliding horizontally during transportation.
