Description

Technical Field

[0001] This utility model relates to the field of lock accessories technology, and in particular to a door lock central control box. Background Technology

[0002] In the current market, pickup truck tailgates, passenger car trunks, and some engine compartment doors often require locks to ensure security and extend their lifespan. These locks are typically used in conjunction with a central locking system. Currently, most central locking systems on the market use a 2-pin socket design. 2-pin sockets lack grounding protection and are susceptible to voltage fluctuations (such as transient interference from the vehicle's 12V power supply, which can cause the control box to restart), resulting in insufficient power supply stability. Furthermore, these central locking systems lack a Bluetooth antenna, limiting the expansion of smart functions such as remote authorization and other IoT features. Users cannot operate the locks via Bluetooth using their mobile phones, reducing the user experience. Therefore, a new central locking system is needed to address these issues. Utility Model Content

[0003] The purpose of this utility model is to provide a door lock central control box to solve the above-mentioned technical problems. The door lock central control box of this utility model adopts a 3P socket design to provide higher power output, improve the stability and response speed of the device operation, and is equipped with a Bluetooth antenna. Users can control the door lock matched with the central control box through Bluetooth on their mobile phones, which is flexible and convenient to use and improves the user experience.
