Embodiment Construction

[0027] In order to make the content of the present invention more obvious and understandable, the following in conjunction with the attached Figure 1-5 and specific implementation methods for further description.

[0028] Such as figure 1 As shown, the deflagration-electromagnetic composite drive bounce mechanism of the present invention includes a cylinder-piston assembly and a linear motor. In this embodiment, the linear motor is a purchased part, and the structure of the linear motor mainly includes three parts: a stator, a mover and a guide rail for linear motion. In order to ensure a good electromagnetic field coupling between the stator and the mover within the stroke range, the core lengths of the stator and the mover are different. The stator of the linear motor is stationary during operation, and the stator is fixedly installed on the casing, and its main function is to generate a rotating magnetic field. The mover of the linear motor moves back and forth. The mov...

Abstract

The invention provides a fire blast-electromagnetic complex drive jumping mechanism which comprises an air cylinder piston assembly and a linear motor. The air cylinder piston assembly comprises a cylinder body, a piston and an igniter; the cylinder body is a barrel with an opened end and a sealed end; an air inlet and an air outlet are formed in the end surface of the sealed end of the cylinder body; a linear motor stator is connected to the opened end of the cylinder body; the piston is arranged in the cylinder body; the bottom part of the piston is connected with one end of a linear motor promoter; the other end of the linear motor promoter is connected with a load; and the ignitor is arranged at the sealed end of the cylinder body. The fire blast-electromagnetic complex drive jumping mechanism has the advantages that the jumping mechanism is used for driving a jumping robot to jump, the characteristics of large instant output force and high power mass ratio of the jumping robot anda legged robot can be met, and the active control on the fire blast drive and the continuous jumping drive of the legged robot can be realized.

Description

technical field [0001] The invention relates to an explosion-electromagnetic compound driving bounce mechanism. Background technique [0002] Drives (actuators) mainly include: mechanical, electromagnetic, heat-mechanical and fluid-type, etc., and detonation drive is a heat-engine drive. Compared with other drive methods, it has simple structure, large energy-to-mass ratio, and instant impact It has the characteristics of large force, but its control is relatively complicated. The traditional thermal drive is to convert linear motion into rotary motion to do work externally. The control of the electromagnetic driving method is simple, but due to the relatively low power-to-mass ratio, a power amplification mechanism is required, and the energy quality is lower than that of the explosive driving method. [0003] The Sandia National Laboratory of the United States designed a gas-fired linear drive mechanism, which was used in a bouncing robot, so that the robot showed superio...
