Description

[Technical Field]

[0001] This application claims priority to U.S. Provisional Application No. 63 / 672,395, filed July 17, 2024.

[0002] The present invention relates to a locking module, and in particular to a locking module for a battery exchange station. [Background technology]

[0003] Battery exchange stations are usually equipped with a battery locking and unlocking mechanism to ensure the stability and safety of the battery during the exchange process. Such mechanisms are mainly implemented by mechanical structures such as hooks, spring structures, and rotary locking modules to secure the battery in a designated position and release it by an unlocking operation when necessary.

[0004] However, conventional battery locking and unlocking mechanisms have certain inherent drawbacks. If a user pulls too hard on the battery during operation, the mechanism can jam. This jamming is often caused by improper application of force, such as when a user attempts to remove the battery before the unlocking process is fully completed, which can leave the locking mechanism partially engaged and lead to interference or deformation of internal moving parts. Furthermore, the complexity of conventional mechanical designs intended to improve operational accuracy can create instability due to assembly errors and component tolerances, further contributing to jamming.

[0005] These issues not only reduce the operational efficiency of battery exchange stations, but also degrade the user experience and may even lead to damage to the batteries and devices themselves. Therefore, improving the battery locking and unlocking mechanism to solve the jamming problem and increase the stability and reliability of operation is a key challenge in this technical field.
