[0002] In recent years, the demand for flexible logistics in industries such as e-commerce and automobile manufacturing has continued to rise, and enterprises urgently need low-cost, highly adaptable intelligent handling solutions. To address the needs of enterprises for warehousing and logistics handling, a warehousing and logistics handling robot has been designed to replace manual handling, thereby reducing workload and improving operational efficiency.
[0003] Traditional warehouse logistics handling robots mostly use Mecanum wheel drive systems. Although they support omnidirectional movement, they have drawbacks such as complex structure, strict requirements for ground flatness, high energy consumption, and easy wear and tear. They are difficult to cope with the dynamic needs of warehouse logistics scenarios, such as frequent shelf adjustments and human-machine mixed operations. Utility Model Content

The stepper motor of the chassis assembly drives the steering wheel assembly to rotate through the synchronous belt drive, thereby realizing the steering of the warehouse logistics handling robot.
[0041] When a warehouse logistics handling robot moves under the shelf during operation, the lifting component activates the electric push rod. The electric push rod converts the horizontal thrust of the electric push rod into a vertical thrust in space through the wedge block of the lifting component and the pallet component. At this time, the connection between the optical axis of the chassis component and the linear bearing of the pallet component realizes the limitation of the pallet component, retaining only one vertical degree of freedom in space, so that the pallet component can be lifted. The final effect is that the pallet component lifts the shelf through the lifting component. Beneficial effects

It adopts a four-steering wheel independent drive scheme, achieving steering control and omnidirectional movement through precision synchronous belt transmission. The innovative use of a wedge-shaped lifting mechanism solves the technical challenge of lifting large loads in confined spaces. It provides SMEs with a cost-effective logistics automation solution, demonstrating significant economic benefits and application value. Attached Figure Description
