A mechanical foot cushioning mechanism

Abstract

The invention discloses a novel robot foot cushioning mechanism, which comprises a movable shaft, the bottom of the movable shaft is provided with mutually connected outriggers, the four corners of the bottom of the movable shaft are provided with connecting parts, four groups of the connecting parts The bottom of the head is provided with interconnected cushioning air cushions, the outer sides of the four groups of cushioning air cushions are provided with protective airbags, and the bottoms of the four groups of cushioning air cushions and outrigger columns are provided with interconnecting connecting plates, and the two connecting plates The side is provided with a positioning and moving assembly, the bottom of the connecting plate is provided with a foot base, and the two sides of the foot base are hinged with arc-shaped hinged seats. The present invention guides and expands activities through arc-shaped hinged seats and universal wheels, and utilizes springs to perform the first activity shock absorption, and provides a support point and guiding function for the device, and cooperates with the force buffer assembly to perform secondary relief, effectively Resolve the impact force on the robot foot, enhance the stability of the robot foot, and enhance the practicability of the device.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a novel robot foot buffer mechanism. Background technique [0002] With the development of various new technologies, various mobile robots are applied to fields such as production handling, hotel services, entertainment, simulation games, medical services, fire protection, and even military affairs. The traveling mechanisms of mobile robots include wheeled, crawler, human-footed, multi-legged and other structures. Human-footed traveling mechanisms are often used to simulate human machines or robots that require bouncing actions. The human-footed mechanisms of such machines It is generally required to have vibration reduction and buffering effects to reduce the damage to the robot foot every time it touches the ground of the object; [0003] When the current robot feet are in contact with the ground, they generally use shock-absorbing structures to directly connect with the human ...

AI Technical Summary

Problems solved by technology

[0003] When the current robot feet are in contact with the ground, they generally use shock-absorbing structures to directly connect with the human feet for buffering. However, whenever the human feet touch the ground, the pressure generated is difficult to have a uniform force-bearing surface on the human feet. and a stable position, so when the human foot is exposed to a large impact force, the supporting force on the bottom of the human foot will be weakened and insufficient due to the lack of sufficient induced guiding force and positioning function, which may be broken during the shock absorption and buffering period. Make the robot fall down, cause damage to the internal structure of the human foot, and reduce the effectiveness and stability of the buffer function of the device. When the robot needs to move its position, it usually moves by itself through the human foot. However, this movement The method is extremely slow, which is not conducive to the normal use and walking of the robot, and reduces the follow-up work efficiency of the robot and the difficulty of the operator's transfer and handling; the legs of the robot are generally only composed of connecting arms, and its internal structure is the weakest. When impacted, it is difficult for the bottom of the human foot to relieve it, and it is easy to knock down the robot, causing losses
