Robot frame structure

Abstract

The invention provides a robot frame structure which is stable in overall structure, light in weight, rapid and convenient to assemble, good in overall rigidity and good in damping performance. The robot frame structure comprises a front frame which is of a double-layer beam structure formed by splicing a plurality of aluminum alloy sections and comprises a first upper-layer frame and a first lower-layer frame; a rear frame which is of a double-layer beam structure formed by splicing a plurality of aluminum alloy sections and comprises a second upper-layer frame and a second lower-layer frame; the rear end faces, protruding out of the first upper-layer frame and the rear longitudinal beam, of rear stand columns arranged in parallel on the rear portion of the front frame are fixedly connected with cross beams and longitudinal beams at the corresponding positions of the second upper-layer frame and the second lower-layer frame; the second lower-layer frame is higher than the first lower-layer frame; the center position of the front end face of the front frame protrudes forwards to form a front axle mounting frame, and the front axle mounting frame is of a double-layer beam structure formed by splicing a plurality of aluminum alloy profiles.

Description

technical field [0001] The invention relates to the technical field of robot structures, in particular to a robot frame structure. Background technique [0002] According to different application fields, intelligent robots can be divided into three categories: industrial robots, industrial application service robots and personal / household robots. The existing service robots need to have a low-cost structure when solving the load-bearing requirements of manned and loaded objects. lightweight. [0003] Most of the existing service robots tend to be unmanned autonomous walking structures. The service robots with manned carriers according to the shape have the shape of a car. The existing robot frames in the form of side cars are generally formed by steel welding, and their weight is relatively large. , and in actual use, it is only a single-layer arrangement, and its stiffness and shock absorption are relatively poor. Therefore, it is urgent to provide a structurally stable an...

[0003] Most of the existing service robots tend to be unmanned autonomous walking structures. The service robots with manned carriers according to the shape have the shape of a car. The existing robot frames in the form of side cars are generally formed by steel welding, and their weight is relatively large. , and in actual use, it is only a single-layer layout, and its stiffness and shock absorption are relatively poor. Therefore, it is urgent to provide a stable and light-weight frame mechanism for service-type robots.
