Abstract

The invention discloses a wheel-track composite type chassis structure. The wheel-track composite type chassis structure comprises a caterpillar baseboard, four electric push rod lifting mechanisms, four Mecanum mobile mechanisms and an omnibearing mobile platform frame, the omnibearing mobile platform frame is fixed to the wheel-track chassis baseboard, push rod top ends of the four electric push rod lifting mechanisms are fixed to the omnibearing mobile platform frame separately, the four Mecanum mobile mechanisms are fixedly connected with the four electric push rod lifting mechanisms, and by extending and retracting electric push rods, the Mecanum mobile mechanisms are in contact with and leave the ground. The wheel-track composite type chassis structure is flexible to move, convenient to operate and reliable to run, and the adaptability to complex terrains is high.

Description

technical field [0001] The invention belongs to the field of robots, and in particular relates to a wheel-track composite chassis structure. Background technique [0002] Due to different practical applications, the design of the mobile mechanism is various, mainly including: wheel type, crawler type, leg type, snake type, etc. Different mechanisms have their own advantages and disadvantages. The wheel mechanism has simple structure, convenient control, flexible movement, and mature technology. It is the most commonly used mobile mechanism, but its adaptability to complex terrain is general; It has high adaptability to the ground when operating in some harsh environments, but its flexibility is poorer than that of the wheeled mechanism, and the driving efficiency is reduced. It can be seen that the chassis designed with a single moving mechanism has a general ability to adapt to complex and changeable environments. [0003] In order to improve the efficiency and adaptabili...
