Problems solved by technology

Combined with the second point above, it can be seen that the higher the requirements for the chassis to overcome obstacles, the smaller the installation distance of the swivel casters, and the worse the overall stability of the chassis
[0007] (4) Since the swivel casters can rotate freely along their installation axis, when encountering a long obstacle with a small angle with the forward direction of the chassis, the swivel casters are very likely to be passively rotated to the direction of the obstacle, thus completely loss of ability to overcome obstacles

Embodiment 1

[0028] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the mobile chassis of this embodiment includes a chassis body 1, driving wheels 2 and driven wheels. There are two driving wheels 2, which are installed on the left and right sides of the chassis body 1 respectively; the driven wheels include two omni-directional wheels 3 (Omni wheels), which are respectively installed on the The front and rear sides of the chassis body 1, and the axis 31 of the omni-directional wheel is parallel to the axis 21 of the driving wheel.

[0029] Such as Figure 4 As shown, the omnidirectional wheel 3 (Omni wheel) is composed of a wheel 32 and some rollers 33 fixed on the outer periphery of the wheel 32. The axis of the wheel is perpendicular to the axis of the roller, and the wheel rotates around the axis. , the rollers are in contact with the ground in turn, and can rotate freely around their own axes. Preferably, the rollers 33 on the spokes are divided into inner ring ...

Abstract

The invention relates to the field of intelligent machines, and discloses a movable type chassis, a robot and a vending machine. The movable type chassis includes a chassis body (1), drive wheels (2)and driven wheels, the two drive wheels (2) are separately installed at the left and right sides of the chassis body (1), the driven wheels include two omni wheels (3) which are separately installed at the front and rear sides of the chassis body (1), and axes (31) of the omni wheels are parallel with axes (21) of the drive wheels. The driven wheels adopt the omni wheels which cannot rotate alongthe mounting axes of the omni wheels, so that the radius of the omni wheels can be enlarged to the greatest extent through the movable type chassis compared with an existing differential steering typechassis, and the larger the radius of the omni wheels, the better the function of obstacle-overstepping is.

Description

technical field [0001] The invention relates to the field of intelligent machines, in particular to a chassis used for walking the intelligent machine, a robot and an automatic vending machine equipped with the chassis. Background technique [0002] At present, mobile robots are roughly divided into omnidirectional mobile chassis and differential steering chassis. Among them, the differential steering chassis is widely used because of its simple structure, high driving efficiency, low control difficulty, and strong ability to overcome obstacles. In the existing differential steering chassis, two driving wheels are respectively arranged on both sides of the chassis center, and one or more driven swivel casters are respectively arranged at the front and back of the chassis. The swivel caster mentioned above can freely rotate along its installation axis, and the wheel center of the swivel caster is arranged behind the installation axis, and the distance between them is usually...
