Abstract

The invention discloses a wheeled mobile robot platform. The platform comprises a machine body, supporting racks, wheels and a control system; the platform is characterized in that the machine body is in rigid connection with the supporting racks below the machine body through bolts; the three or more supporting racks are mounted on the lower surface of the machine body uniformly; each supporting rack comprises a supporting rack base, a moving unit and a linear motion unit; the upper end of the supporting rack base is connected with the lower surface of the machine body; the supporting rack base is a hollow column body; both the moving unit and the linear motion unit are positioned in the supporting rack base; axes of the supporting rack base, the moving unit and the linear motion unit are parallel to one another, and perpendicular to the plane of the machine body; the moving unit is a sliding part which is matched with the supporting rack base; the supporting rack base and the moving unit form a moving pair which is driven by the linear motion unit; the lower end of the moving unit is connected with the wheels symmetrically arranged at the lower part of the moving unit; the wheels are motor-driven wheels.

Example Embodiment

[0020] Example 1
[0021] In this embodiment, the number of support frames 2 is 3. The linear motion unit 23 adopts a ball screw type linear motion unit. The support frame base 21 is a hollow cylinder with a cavity inside. The linear motion unit 23 is installed on the support frame base. In the cavity of the seat 21, the moving unit 22 is a sliding part that cooperates with the supporting frame base 21. The supporting frame base 21 and the moving unit 22 constitute a moving pair. The supporting frame base 21, the moving unit 22 and the linear motion unit 23 The axes of the three are parallel and perpendicular to the plane of the body 1. The moving pair is driven by the linear motion unit 23, and the lower end of each moving unit 22 is symmetrically arranged on two wheels 3, and the wheels 3 are motor-driven wheels.

Example Embodiment

[0022] Example 2
[0023] In this embodiment, the number of support frames 2 is 5. The linear motion unit 23 adopts a belt-driven linear motion unit. The support frame base 21 is a hollow square prism with a cavity inside. The linear motion unit 23 is installed on the support frame base. In the cavity of the seat 21, the moving unit 22 is a sliding part that cooperates with the supporting frame base 21. The supporting frame base 21 and the moving unit 22 constitute a moving pair. The supporting frame base 21, the moving unit 22 and the linear motion unit 23 The axes of the three are parallel and perpendicular to the plane of the body 1. The moving pair is driven by the linear motion unit 23, and the lower end of each moving unit 22 is symmetrically arranged on the two wheels 3. The wheel 3 is an active movement mechanism, and relying on its built-in motor drive, it can drag the platform to move, thereby realizing the forward, backward and differential turning of the platform.

Example Embodiment

[0024] Example 3
[0025] In this embodiment, the number of support frames 2 is 8, the linear motion unit 23 adopts a pneumatic linear motion unit, the support frame base 21 is a hollow prism body with a cavity inside, and the linear motion unit 23 is installed on the support frame base 21 In the cavity of, the moving unit 22 is a sliding part that cooperates with the support base 21. The support base 21 and the moving unit 22 constitute a moving pair, and the support base 21, the moving unit 22 and the linear motion unit 23 are three The axis is parallel and perpendicular to the plane of the body 1. The moving pair is driven by the linear motion unit 23, and the lower end of each moving unit 22 is symmetrically arranged on the two wheels 3. The wheel 3 has the initiative of mechanical movement and relies on its built-in motor drive to drag the platform to move, thereby realizing the forward, backward and differential turning of the platform. When the platform is walking on uneven terrain, under the control of the control system, each support frame 2 is adjusted in real time. Under the premise of ensuring the stability of the platform, the wheels 3 are raised in time when obstacles are encountered, and they fall in time after the obstacles (see image 3 ), in order to achieve the purpose of the body 1 passing through rough terrain efficiently in a horizontal attitude.
