AI Technical Summary
Technical Problem
Existing electronic padlocks are prone to damage when the battery is replaced, resulting in a shortened lifespan, and there are safety hazards during the charging process.
Method used
The positive and negative electrode springs are directly connected to the positive and negative terminals of the battery, replacing the traditional battery wire connection. Combined with the cantilever structure and snap-fit design, the reliability and convenience of battery replacement are ensured, and the risk of impurities entering is reduced by the sealing ring.
Benefits of technology
This reduces the risk of damage to electronic padlocks when replacing batteries, extends the lifespan of electronic padlocks, and improves the convenience and security of battery replacement.

Abstract
This application provides an electronic padlock with easy battery replacement, including a lock body housing, a battery compartment assembly, a main board, and a dust cover. Both the battery compartment assembly and the main board are housed within the lock body housing. The lock body housing has a first opening for the battery compartment assembly to enter and exit. The dust cover is installed on the lock body housing and is used to close or open the first opening. The battery compartment assembly includes a battery case, a battery, a positive terminal spring, and a negative terminal spring. The battery case houses the battery. The positive and negative terminal springs are installed in the battery case. The positive terminal spring is electrically connected to the positive terminal of the battery and includes a positive cantilever arm that is electrically connected to the main board. The negative terminal spring is electrically connected to the negative terminal of the battery and includes a negative cantilever arm that is electrically connected to the main board. By connecting the positive terminal spring to the positive terminal of the battery and the negative terminal spring to the negative terminal of the battery, replacing the method of connecting the battery with a battery wire, the risk of damage during battery replacement is reduced, thus extending the lifespan of the electronic padlock.
