Problems solved by technology

Therefore, the Mecanum wheel mobile platform has high requirements on the smoothness of the road surface. A slight unevenness of the road will easily cause the center of gravity to be unstable during operation, resulting in large shaking, which will make the mobile platform unstable.
When the flatness of the road surface is not good and its four wheels cannot touch the ground at the same time, the mobile platform cannot achieve good omnidirectional movement, and it cannot give full play to its advantages.
[0003] The pressure of the existing mecanum wheels cannot be adjusted according to the load and ground conditions, and the platform has poor running stability and obstacle-surmounting ability

Abstract

An independent suspension mechanism for an omni-directional mobile platform includes two symmetrically arranged mecanum wheels, driving devices are connected to the inner sides of the mecanum wheels,and damping mechanisms are connected to mounting brackets at the outer sides of the mecanum wheels; spring guide rods are arranged at both sides of reduction gears, the top portions of the spring guide rods are connected with a car body mounting plate, and the bottom portions of the spring guide rods are connected with the mounting brackets, and the middle of the spring guide rods are sleeved withfirst rectangular cross-section springs; and a closed structure is formed by the two mecanum wheels through the car body mounting plate, the mounting brackets, and a connecting plate. According to the independent suspension mechanism for the omni-directional mobile platform, the pressure can be adjusted according to the load and ground conditions under multiple different environmental conditions,the influence of the ground on the running process of the mecanum wheels can be reduced, and the phenomenon of suspension of a certain group of wheels due to the unevenness of the ground is avoided;and the independent suspension mechanism for the omni-directional mobile platform has the advantages of stable operation of the platform, strong ability to overcome obstacles, and high bearing capacity.

Description

technical field [0001] The invention relates to the technical field of a Mecanum wheel mobile platform, in particular to an independent suspension mechanism of an omnidirectional mobile platform. Background technique [0002] At present, the mecanum wheel is widely used in the field of omnidirectional intelligent mobile equipment, but its omnidirectional mobile equipment must be on a stable ground to run according to the predetermined trajectory. Therefore, the Mecanum wheel mobile platform has high requirements on the smoothness of the road surface. A slight unevenness of the road will easily cause the center of gravity to be unstable during operation, resulting in large shaking, which will make the mobile platform unstable. When the flatness of the road surface is not good and its four wheels cannot touch the ground at the same time, the mobile platform cannot realize good omnidirectional movement, and it cannot give full play to its advantages. [0003] The pressure of t...
