[0002] Logistics robots refer to automated equipment that is widely used in warehousing, logistics, transportation and other industries, and is designed for automatic handling, sorting, storage and other logistics operations of goods. At present, these logistics robots need to be equipped with a special chassis platform when in use;

[0003] The sizes and specifications of logistics robots of various brands and models on the market are all different. Even if they are from the same manufacturer, the size differences between models are significant. This diversity requires the corresponding chassis platform to be highly flexible to adapt to different robot sizes. However, most chassis platforms on the market tend to be customized, which seriously limits their versatility. Although some chassis platforms allow a certain degree of size adjustment, the adjustment process often leads to an imbalance in the center of gravity, reducing the stability when carrying robots of different sizes and increasing the risk of tilting or even collapse during work, which directly threatens the safety of operations and the reliability of logistics robot operations. Utility Model Content

[0004] In view of this, the utility model provides a logistics robot chassis platform, which can quickly adjust the size of the chassis platform through the coordinated cooperation of an adjustment mechanism, a support assembly and a drive assembly, so that the logistics robot chassis platform can match logistics robots of different sizes, thereby realizing the versatility of the logistics robot chassis platform. At the same time, the entire adjustment mechanism and the chassis platform can provide a stable support base point, which not only enhances the stability of the chassis platform when carrying robots of different sizes, but also effectively prevents the risk of tilting or collapse, thereby ensuring the high safety and reliability of the logistics robot during operation.

[0005] In order to solve the above technical problems, the utility model provides a logistics robot chassis platform, including a chassis frame and an adjustment mechanism symmetrically arranged at the four corners of the chassis frame, the adjustment mechanism including guide slide grooves symmetrically arranged at the four corners of the chassis frame, the guide slide grooves are slidably connected with sliding support plates, a circular cavity is provided in the middle of the chassis frame, a screw rod is rotatably connected in a rotating hole arranged between the circular cavity and each guide slide groove, the outer ends of the screw rods are respectively threadedly connected to the corresponding screw holes on the adjacent sliding support plates on the same side, the outer ends of the lower surfaces of the sliding support plates are provided with support components, and a driving component for driving the screw rod to rotate is also provided in the circular cavity.

[0006] The support assembly includes mounting grooves respectively arranged at the outer end heads of the lower surface of the sliding support plate, the outer end heads between the left and right walls of the mounting grooves are rotatably connected to support rods, and the inner end heads of the support rods are rotatably connected to support guide wheels, each mounting groove is provided with a rectangular groove at the upper end of the inner wall surface near the outer end head of the inner support rod, a rectangular rod is provided in the rectangular groove, a rack plate is slidably connected to the outside of the rectangular rod, an arc-shaped groove arranged in the middle part of the outer arc surface of the support rod is provided in the arc-shaped groove, and the arc-shaped tooth plates are respectively meshed and connected with the rack plates adjacent to the same side; the support assembly also includes electric push rods respectively arranged in the middle part of the top wall surface of the mounting grooves, and the outer end heads of the telescopic ends of the electric push rods are respectively fixedly connected to the inner side faces of the rack plates adjacent to the same side.

[0007] The driving assembly includes bevel gears 1 respectively arranged on the inner end of the screw rod, and bevel gear 2 is rotatably connected to the middle of the top wall of the circular cavity, and bevel gear 1 is meshed with bevel gear 2; the driving assembly also includes a motor arranged in the middle of the bottom wall of the circular cavity, and the upper end of the output shaft of the motor is fixedly connected to the lower end face of bevel gear 2.

[0010] The beneficial effects of the above technical solution of the utility model are as follows:

[0011] 1. In order to adapt to logistics robots of various specifications, relevant staff control the operation of the motor through an external single-chip computer. The rotation of the motor output shaft drives the synchronous rotation of bevel gear 2. When bevel gear 2 rotates, it drives the screw to rotate synchronously through the bevel gear 1 meshing with it. The rotation of the screw drives the sliding support plate to move outward along the guide groove and unfold. In this way, the size of the chassis platform can be quickly adjusted, so that the logistics robot chassis platform can match logistics robots of different sizes, realizing the versatility of the logistics robot chassis platform.

[0012] 2. When the sliding support plate moves out beyond the set distance, the external single-chip microcomputer controls the operation of the electric push rod, and the telescopic end of the electric push rod retracts, pulling the rack plate to move inward along the rectangular rod. When the rack plate moves, it drives the support rod to rotate around its axis through the arc-shaped toothed plate meshing with it, so that the support guide wheel contacts the ground, thereby supporting the sliding support plate and its ancillary mechanisms, providing a stable support base for the entire adjustment mechanism and chassis platform, which not only enhances the stability of the chassis platform when carrying robots of different sizes, but also effectively prevents the risk of tilting or collapse, ensuring the high safety and reliability of the logistics robot during operation.
