Embodiment Construction

[0026] The details of the present invention can be understood more clearly in combination with the drawings and the description of the specific embodiments of the present invention. However, the specific embodiments of the present invention described herein are only used to explain the purpose of the present invention, and cannot be construed as limiting the present invention in any way. Under the teaching of the present invention, the skilled person can conceive any possible modifications based on the present invention, and these should be regarded as belonging to the scope of the present invention. It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "installation", "connec...

Abstract

The invention discloses a waist joint mechanism and a robot and relates to the technical field of humanoid robots. The waist joint mechanism comprises a waist ball seat, a waist ball cap and a waist ball. A containing cavity is formed jointly by the waist ball seat and the waist ball cap. The inner sidewall of the containing cavity is provided with a first sunken part and a second sunken part which are symmetric. The waist ball is arranged in the containing cavity. The sidewall of the waist ball is provided with a first limiting protrusion and a second limiting protrusion which are symmetric. The first limiting protrusion is inlaid in the first sunken part. The second sunken part is inlaid in the second sunken part. Gaps are formed between the upper end face and the lower end face of the first limiting protrusion and the wall face of the first sunken part. Gaps are formed between the upper end face and the lower end face of the second limiting protrusion and the wall face of the second sunken part. The waist joint mechanism can have high impact resistance when the robot makes contact with the ground, can enable the waist of the robot to bend down in multiple directions in the moving process of the robot. The waist joint mechanism has low requirements for manufacturing and installation precision and is convenient to produce, simple in structure and light in weight.

Description

Technical field [0001] The invention relates to the technical field of humanoid robots, in particular to a waist joint mechanism and a robot. Background technique [0002] Humanoid robot is an advanced development stage of advanced robot technology. It comprehensively embodies the research and development level of advanced robots in many aspects such as mechanism, motion and dynamics, and is a complex integrated system. Among them, the waist joint of a humanoid robot is one of the difficulties in the design of a humanoid robot. The waist joint is added to the humanoid robot. The purpose is to improve the stability of the robot's walking and continuous and fast walking, so that the humanoid robot can realize the coordinated movements of the entire body (upper limbs, lower limbs and waist) like a human, while also completing Various jobs. The waist of the humanoid robot must not only realize the flexible waist bending function, but also have the characteristics of shock resistanc...
