Gas-driving jumping device

Abstract

The invention provides a gas-driving jumping device which comprises a cylinder body, a piston and at least one elastic element, wherein the top end of the cylinder body is sealed by an upper cylinder cover; an opening is formed on the bottom of the cylinder body; the cylinder body is fixedly connected with the upper cylinder cover; a pressure detection port, an exhaust port and an ignition device are arranged on the upper cylinder cover; the ignition device is located on the inner side of the upper cylinder cover; a first level step, a second level step and a third level step are respectively formed in a top-wide bottom-narrow form on an inner side wall of the cylinder body; the exhaust port is controlled by an exhaust solenoid valve; the piston is located in the cylinder body in a drawing form; the piston is hollow; the top of the piston is opening; the bottom of the piston is fixedly connected with a base; a gas inlet is formed on the side wall of the lower part of the base; the gas inlet is controlled by an inlet solenoid valve; a lug boss is arranged at the top end of the piston; the lug boss is connected with the top end of the elastic element; the bottom end of the elastic element is connected with the second level step. The gas-driving jumping device has the advantages that the locking force is large, the gas purity can be effectively ensured, the structure is compact, the mounting and dismounting are convenient, and the gas-driving jumping device has high-efficient ignition device and higher space use rate so that the robot has higher extreme obstacle-crossing ability and higher flexibility and maneuverability.

Description

technical field [0001] The invention relates to a gas-driven jumping device. Background technique [0002] Mobile robots can be divided into three modes of movement: one is wheel drive, which is the driving mode of most mobile robots, ranging from various remote control toy robot cars or autonomous robot cars to large ones on the battlefield. Unmanned chariots or alien surface environment detectors in interstellar exploration, etc.; one is crawler-driven, this type of robot has better obstacle-surmounting ability and terrain adaptability than wheeled robots, so it can be used in general urban environments and in the wild. The environment is applicable, but the moving speed of the crawler drive is weaker than that of the wheel drive; there is also a bionic crawling or walking method, such as: snake robots, robot reptiles and various robot insects, etc., these Robots are generally designed for a specific application. However, wheeled or tracked robots can only work on relati...

Problems solved by technology

However, this kind of device has problems such as complex structure, inconvenient disassembly, low space utilization rate due to the use of double pistons, low locking force, inability to detect the internal pressure of the piston, and unreasonable setting of the exhaust hole.
