Solution Overview
Problem
Existing suspension systems for service robots are complex, costly, and inadequate for robots with high gravity centers, limiting their ability to navigate rough terrain and adapt to diverse ground conditions.
Innovation Solution
A simplified suspension system comprising a U-shaped fixing frame, a slidable suspension frame, and a hub motor-driven wheel, with elastic members and sliding grooves allowing vertical adjustment to enhance stability and obstacle crossing capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle suspension systems are used for service robots, then obstacle-crossing capability is improved, but structure complexity increases
Solution Approach 1:
The suspension system is divided into independent modular units, each consisting of a sliding groove, elastic member, and suspension frame. This segmentation allows the complex suspension function to be achieved through simple, repeatable modules that can be independently manufactured and assembled, reducing overall system complexity while maintaining obstacle-crossing capability
Solution Approach 2:
Instead of using a complex vehicle-style suspension system, the patent inverts the approach by using a simplified mechanism where the suspension frame slides vertically within the fixing frame guided by sliding grooves. The elastic members provide suspension force in a direct, straightforward manner opposite to the complex multi-link mechanisms of vehicle suspensions
2Adaptability or versatility
If vehicle suspension systems are used for service robots, then obstacle-crossing capability is improved, but manufacturing cost increases
Solution Approach 1:
The patent employs simple, inexpensive components such as elastic members (springs), sliding grooves, and basic mechanical joints that can be manufactured at low cost. These components are replaced or reset rather than repaired, following a disposable approach that reduces manufacturing complexity and cost while maintaining the required obstacle-crossing function for service robots

AI summary
The present disclosure provides a suspension system, and a chassis with the same. The system includes: a fixing frame having an opening; a suspension frame disposed at the opening; and a driving wheel rotationally coupled to the suspension frame. In which, two ends of the suspension frame are respectively disposed on two ends of the fixing frame at the two sides of the opening to be selectively moved up and down along a height direction of the fixing frame, and two elastic members are respectively disposed between each of the two ends of the suspension frame and the corresponding end of the fixing frame at the two sides of the opening. In the present disclosure, the fixing frame and the suspension frame can move with respect to each other in a vertical direction, and the resetting adjustment is realized through the elastic member.
