Description

Technical Field

[0001] The utility model belongs to the field of bionic machinery, and particularly relates to a mechanical structure of a simulated animal. Background Art

[0002] Robot technology is a high-tech that has developed rapidly in recent decades. It integrates the latest research results of multiple disciplines such as machinery, microelectronics and computer, automatic control, sensors and information processing, and artificial intelligence, and is a typical carrier of mechatronics technology.

[0003] Large bionic animal-shaped machinery is an important application of robots and is widely used in fields such as entertainment and film and television. Its basic requirement is that the mechanical structure can imitate the basic movement characteristics of animals. Therefore, the large bionic machinery that realizes the above functions is actually a complex mechanical structure. The components and connection points of the complex mechanical structure are generally numerous, and the potential failure sources also increase accordingly. Moreover, any failure may affect the operation of the entire system. The utility model CN202122585300.9 discloses a movable reindeer stunt structure, including a reindeer body composed of a fixed skeleton, a motor arranged in the reindeer body, a front limb device and a hind limb device respectively connected to the reindeer body. The front limb device is a movable device relative to the reindeer body, the hind limb device is fixed to the ground, the motor drives the front limb device to make a swinging motion, and the front limb device includes a calf assembly, a thigh assembly connected to the calf assembly, and a four-bar mechanism connected to the calf assembly and the thigh assembly. The front limb device of the above structure has a complex structure, is difficult to manufacture and install, and has a high maintenance cost. The hind limb device is fixed to the ground and cannot move, and the imitation of the basic movement characteristics of animals is not in place. Moreover, it can only imitate one kind of animal, namely reindeer, and cannot be reused.

[0004] Therefore, there is a need for a new large bionic machinery that can vividly imitate the movement characteristics of multiple animals, and has a simple structure, is convenient for installation and driving, and has a low maintenance cost. Summary of the Invention
