Embodiment Construction

[0025] Further description will be given below in conjunction with the embodiments shown in the accompanying drawings.

[0026] The jumping leg based on the incomplete gear set as shown in the figure includes a frame, an energy storage spring installed on the frame, and a transmission assembly that presses on the frame to deform the energy storage spring to store energy or release energy for jumping;

[0027] In the frame, the pointed forefoot 5 and the J-shaped rear foot 6 are hinged to form a main body that stands firmly on the ground, and the U-shaped connector 4 is hinged at the top of the pointed forefoot.

[0028] The energy storage spring includes a lower joint torsion spring 10 and an upper joint torsion spring 9; the lower joint torsion spring is installed at the hinge point of the pointed forefoot and the J-shaped rear foot, and the two ends of the spring apply force to the pointed forefoot and the J-shaped rear foot respectively. Type hind foot ( Figure 4 It can b...

Abstract

The invention relates to a bouncing robot and aims to provide a bouncing leg based on an incomplete set of gears. The bouncing leg has the characteristics of high kinetic energy conversion efficiency,continuous jumping and stable and reliable bouncing. The technical scheme is as follows: a bouncing leg based on an incomplete gear set is characterized in that the bouncing leg comprises a frame, anenergy storage spring mounted on the frame and a transmission component which presses the frame to make the energy storage spring deform, accumulate or release energy to jump; The machine frame comprises a main body formed by the hinged connection of the pointed forefoot and the J-shaped hind foot and standing on the ground, and a U-shaped connector hinged on the top end of the pointed forefoot;The energy storage spring comprises a lower joint torsion spring installed at the hinge point of the point-type forefoot and the J-type hindfoot and biased at both ends of the point-type forefoot andthe J-type hindfoot respectively, and an upper joint torsion spring installed at the hinge point of the point-type forefoot and the U-type connector and biased at both ends of the point-type forefootand the U-type connector respectively.

Description

technical field [0001] The invention relates to a bouncing robot, in particular to a leg type bouncing mechanism. Background technique [0002] The jumping machine has a wide range of prospect applications and important strategic significance because of its efficient obstacle jumping. In recent years, more and more researchers have paid attention to the research on the performance of jumping robots. In the research of jumping robots, many of them imitate creatures with jumping ability, such as kangaroos and locusts. The current movement modes of ground mobile robots mainly include wheeled and tracked, and they have been widely used in military reconnaissance and interstellar exploration. However, robots such as wheeled and tracked have the shortcoming of poor obstacle-surmounting ability. [0003] Carnegie Mellon University in the United States has developed a bow-legged jumping robot imitating kangaroos. The robot weighs 2.5kg, and uses 100N·m / kg unidirectional glass fib...
