AGV Chassis Swing-Arm Mechanism for Fast Wheel Pressure Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional AGV chassis mechanisms require complex operations and low efficiency in adjusting parameters like driving wheel pressure, vehicle body horizontal state, and ground adaptability due to the need for replacing springs in wheel assemblies.
Innovation Solution
The AGV chassis mechanism employs a dual differential design with driving and universal wheel assemblies, utilizing hinge bases, swing arms, and elastic members to adjust parameters without replacing springs, facilitated by adjustable nuts and bushes to limit positions and provide floating buffers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If springs of wheel assemblies are replaced to adjust parameters, then parameter adjustment capability is improved, but operation complexity and time consumption increase
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the swing arm can be rotated to different angles relative to the driving wheel assembly, allowing real-time adjustment of parameters such as driving wheel positive pressure and vehicle body horizontal state without replacing springs. This dynamic repositioning enables continuous adaptation to different operational requirements
Solution Approach 2:
The patent changes the geometric parameters of the swing arm structure, specifically the distance between the first hinge base and second hinge base, and the angle of the swing arm relative to the driving wheel assembly. By adjusting these parameters, the system achieves different wheel pressures and vehicle attitudes without physical replacement of elastic members
2Adaptability or versatility
If springs of wheel assemblies are replaced to adjust parameters, then parameter adjustment capability is improved, but operation complexity increases
Solution Approach 1:
The swing arm is designed to be rotatable relative to the driving wheel assembly through a hinge connection, allowing operators to adjust parameters by simply rotating the swing arm to different angular positions. This dynamic adjustment mechanism eliminates the complex procedure of spring replacement and reduces operational complexity
Solution Approach 2:
The swing arm acts as an intermediary element between the driving wheel assembly and the vehicle body. By adjusting the swing arm's position and angle, operators can indirectly control parameters such as wheel positive pressure and vehicle horizontal state, simplifying the adjustment process compared to direct spring replacement

AI summary
An AGV chassis mechanism and an AGV with the mechanism are disclosed. The AGV chassis mechanism includes a chassis (300) and a travelling mechanism that includes two driving wheel assemblies (100) respectively arranged at left and right sides of the chassis (300) and two universal wheel assemblies (200) respectively arranged at front and rear ends of the chassis (300). The driving wheel assembly (100) includes a first hinge base (110), a second hinge base (120), a swing arm (130), a swing rod (140) and a driving wheel (150). The first hinge base (110) and the second hinge base (120) are fixed to the chassis (300) and spaced from each other. The swing arm (130) has a first end hinged to the first hinge base (110) and a second end extending toward the second hinge base (120). The swing rod (140) has an upper end and a lower end that is hinged to the second hinge base (120), the second end of the swing arm (130) is sleeved on the swing rod (140), the upper end of the swing rod (140) is screwed with a first adjusting nut (141), and a first elastic member (142) is arranged between the first adjusting nut (141) and the swing arm (130). The driving wheel (150) is installed on the swing arm (130). Two said driving wheel assemblies (130) are symmetrically arranged on the left and right sides of the chassis (300). The AGV chassis may adjust parameters such as a positive pressure of the driving wheel, a horizontal state of a vehicle body, and a ground adaptability without replacing the elastic members, which simplifies adjustment operations and improves adjustment efficiency.
