Problems solved by technology

[0003] Although a variety of battery replacement methods have emerged, such as using a mobile battery replacement car to transport batteries to automatically replace battery components, during the battery replacement process, due to the limited space at the bottom of the vehicle, the battery replacement car cannot easily enter and exit the bottom of the vehicle after carrying the battery components. If the buried track is adopted, the overall infrastructure requirements of the power exchange station are high, the construction project takes a long time, and the maneuverability is poor; if the vehicle is lifted, the lifting mechanism is required to be high, and the lifting space is relatively large, which affects the overall power exchange. The safety control of the process is difficult and consumes a lot of energy
[0004] In the process of battery replacement, it is necessary to replace the bottom battery pack accurately, and the position of the vehicle or mobile battery replacement car needs to be adjusted. However, when positioning and adjusting the vehicle or mobile battery replacement car, it is inevitable that there will be There are errors. In order to make the positioning and alignment actions go smoothly, the target object needs to be able to float freely, that is, the contact surface between the mobile battery swap trolley and the battery pack and the support surface that is in contact with the vehicle need to be floatable, but the existing mobile battery swap The trolley can only satisfy a small range of floating in the upper and lower ranges, and at the same time cannot adjust the position in the horizontal plane, making it difficult to carry out the battery replacement process accurately and efficiently; but it is very easy to deviate from the middle position during the floating process in the horizontal direction. The lateral force generated back to the center makes the battery replacement process unstable, resulting in unnecessary bumps during installation and removal, which affects battery life

Abstract

The invention provides a battery swapping method without lateral force on a battery swapping platform, comprising the steps of: taking out a power-depleted battery, lifting the floating platform by a lifting mechanism on the swapping platform, aligning the locking mechanism with a locking device, and locking the floating platform by a clamping mechanism at the same time, To eliminate the lateral force of the floating platform to restore the balance position; to replace the fully charged battery, the transfer device transports the battery assembly to be replaced to the battery replacement position, and the lifting mechanism of the battery replacement platform lifts the battery assembly to the preset installation position of the lifting mechanism. The battery replacement platform can be floated in all directions to carry the battery components and use the locking device to lock the battery components to be replaced to the bottom of the vehicle. The invention is ingenious in design and rigorous in logic, reduces the vertical dimension of the transfer device, and allows the battery components to float in all directions at the same time, reduces the positioning requirements for the device, eliminates the lateral force generated during the floating process, and avoids battery Unnecessary collision of components occurs, which meets the requirements of fast battery replacement for new energy vehicles and is convenient for popularization and application.
