Floating Battery Swap Restoring Mechanism for Non-Axial Force Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floating alignment devices for battery swap robots, which use springs as restoring mechanisms, often fail due to non-axial forces causing torsion and offset, leading to poor floating effects, increased failure rates, and potential damage to batteries and vehicles during alignment.
Innovation Solution
A restoring mechanism for a floating battery swap device utilizing a guide sleeve, guide rod, and elastic member, where the guide rod slides within the sleeve to counteract non-axial forces, ensuring only axial movement of the elastic member, and an adjustment member allows pretension force adjustment to enhance stability and service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a spring is used as a restoring mechanism in a floating alignment device, then the device can automatically restore to its initial position, but the spring is prone to failure due to non-axial forces causing torsion and offset
Solution Approach 1:
The restoring mechanism is divided into multiple independent linear restoring units, each consisting of a separate linear restoring element connected to the floating platform. This segmentation allows each element to work independently along its own axial direction, preventing the torsion and offset that plague single spring systems.
Solution Approach 2:
Linear restoring elements are introduced as intermediary components between the floating platform and the fixed structure. These elements mediate the restoring force in a controlled manner, ensuring that forces are applied axially rather than creating non-axial torsion on a single spring.
2Ease of operation
If a spring is used as a restoring mechanism, then restoration function is provided, but the floating effect is poor due to irregular torsion and offset
Solution Approach 1:
The restoring mechanism is divided into multiple independent linear restoring units, each consisting of a separate linear restoring element connected to the floating platform. This segmentation allows each element to work independently along its own axial direction, preventing the torsion and offset that plague single spring systems.
Solution Approach 2:
The patent changes the physical parameters of the restoring mechanism by using linear restoring elements with specific structural characteristics (rod-like, axial symmetry) rather than coiled springs. This parameter change ensures that the restoring force is always applied axially, improving floating stability and alignment performance.
3Loss of time
If a spring is used as a restoring mechanism, then automatic restoration is achieved, but device complexity increases due to non-axial force generation and failure modes
Solution Approach 1:
The patent employs multiple simple linear restoring elements that are structurally simpler and more robust than springs. While there are multiple elements, each individual element is simpler in design, easier to manufacture, and less prone to failure, reducing the overall complexity of the restoring mechanism.

AI summary
A restoring mechanism (128) for a floating battery swap device. The floating battery swap device comprises a fixed portion (11) and a floating portion (12). The floating portion (12) can float relative to the fixed portion (11). The restoring mechanism (128) comprises: a guide sleeve (1283), which is connected to one of the floating portion (12) and the fixed portion (11) and has a cavity and a first opening located at a first end thereof; a guide rod (1284), with a first end thereof slidably extending into the cavity from the first opening, and a second end thereof abutting against the other of the fixed portion (11) and the floating portion (12); and an elastic member (1281) arranged in the cavity, with a first end thereof being connected to the first end of the guide rod (1284). The restoring mechanism can counteract a non-axial force by means of sliding of the guide rod and the floating portion, thereby extending the service life of the elastic member and enhancing the floating effect of the floating battery swap device, so as to solve the problems that a spring in the existing floating alignment device is easy to fail and that the floating effect of same is poor. A floating battery swap device and a battery swap method are further provided.
