AI Technical Summary

Technical Problem

The existing humanoid robots have a lot of joint freedom and high power consumption, which leads to heavier weight in the whole machine, and the torso components need to be strong to prevent deformation, which increases the weight of the whole machine.

Method used

The three-sided fit design of the battery box and the torso assembly are adopted. The three outer surfaces of the battery box fit with the motherboard and side panels of the torso assembly respectively, which enhances the stiffness of the torso assembly and reduces the size and thickness of the torso assembly. The battery box is removable and connected for easy installation and maintenance.

Benefits of technology

By enhancing the stiffness of the trunk assembly, reducing the volume and weight of the trunk assembly, increasing the device layout space, simplifying the overall machine structure, and reducing the weight of the entire machine.

Abstract

The utility model provides a robot trunk structure and a robot, and relates to the technical field of robots. The robot trunk structure comprises a trunk assembly and a battery box arranged on the trunk assembly, the trunk assembly comprises a main plate and two opposite side plates arranged on the main plate, the battery box is fixed between the two side plates, the battery box is provided with a first surface, a second surface and a third surface, the second surface and the third surface are opposite, the first surface is attached to the main plate, and the third surface is attached to the main plate. The second surface and the third surface are attached to the two side plates respectively. In the robot trunk structure, the three outer surfaces of the battery box are attached to the main plate and the two side plates of the trunk assembly correspondingly, then the battery box can play a role in resisting deformation of the trunk assembly and enhancing the rigidity of the trunk assembly, and therefore the weight of the whole robot is reduced. Meanwhile, the trunk assembly also supports and protects the battery box, and a structure for supporting and protecting the battery box does not need to be additionally arranged, so that the weight of the whole machine is further reduced, and the structure of the whole machine is simplified.
