Embodiment Construction

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0026] Such as Figure 1-3 As shown, an omnidirectional all-wheel drive mobile robot chassis with independent suspension includes a plurality of omnidirectional all-drive modules, a base plate 14, and two U-shaped plates 13 fixedly connected to both sides of the base plate 14 respectively. The modules are installed on the U-shaped board 13, and each omnidirectional all-drive module includes a RR rotating platform 10, an independent suspension, a wheel 1 and a first power unit for driving the wheel 1 to rotate along the wheel axis, and the RR rotating platform 10 is controlled by the second The power unit is driven and can rotate around the Z axis. The upper part of the independent suspension is fixed on the lower end of the RR rotating platform 10, ...

Abstract

The invention discloses an omnidirectional totally driven mobile robot chassis with independent suspensions. The omnidirectional totally driven mobile robot chassis with the independent suspensions comprises a plurality of omnidirectional totally driven modules, a bottom plate and two U-shaped plates which are separately fixedly connected to two sides of the bottom plate; the omnidirectional totally driven modules are mounted on the U-shaped plate; each omnidirectional totally driven module comprises an RR rotary platform, the corresponding independent suspension, wheels and a first power unitfor driving the wheels to rotate along wheel axles; each RR rotary platform is driven by a second power unit and can drive a part below the RR rotary platform to rotate around a Z axis; the upper portion of each independent suspension is fixedly connected to the lower end of the corresponding RR rotary platform; the lower end of each independent suspension is fixedly connected with the corresponding first power unit; each independent suspension comprises an elastic element and is used for maintaining the corresponding wheels to touch the ground all the time and absorbing shock of the robot chassis. Omnidirectional movement and independent shock absorption of the robot chassis can be realized, and the structure is simple.

Description

technical field [0001] The invention belongs to the field of robots, and in particular relates to an omnidirectional and all-drive mobile robot chassis with an independent suspension. Background technique [0002] With the attention of the national macro-strategy, the research on mobile robots in my country has entered an unprecedentedly popular period. A variety of mobile robot chassis gradually come into people's sight. The mobile robot chassis that moves in a limited space and can realize the function of moving at any angle is an important direction of research in recent years. In the prior art, omnidirectional and mobile robot chassis with suspension are various, which basically meet the functions, but there are still some deficiencies. [0003] For example, the utility model patent with the patent application number CNN202242837U discloses a robot electric walking device with independent suspension. The suspension is composed of an upper cross arm, a lower cross arm, ...
