Circuit board and intelligent door lock
The invention relates to the technical field of circuit boards, and discloses a circuit board and an intelligent door lock, and the circuit board comprises a substrate which is provided with a power module; the charging interface is arranged on the substrate; the charging interface is suitable for being connected with an external power supply; a charging positive electrode of the charging interface is electrically connected with a positive electrode of the power supply module, and a charging negative electrode of the charging interface is electrically connected with a reference ground on the substrate; the coating structure is made of a conductive material; the coating structure is electrically connected with the charging negative electrode of the charging interface and the reference ground at the same time. According to the embodiment of the invention, the coating structure is arranged, so that the connection between the charging cathode of the charging interface and the reference ground is more stable. Meanwhile, due to the fact that the wrapping structure is made of the conductive material, it can be guaranteed that the negative electrode is not fused by current when the intelligent door lock is charged during high-power charging, and therefore normal use of the intelligent door lock is guaranteed.
本发明涉及电路板技术领域，公开了一种电路板及智能门锁，该电路板包括：基板，设置有电源模块；充电接口，设置在所述基板上；所述充电接口适于与外界电源连接；所述充电接口的充电正极与所述电源模块的正极电连接，所述充电接口的充电负极与所述基板上的参考地电连接；包覆结构，由导电材质制成；所述包覆结构同时与所述充电接口的充电负极以及所述参考地电连接。本发明实施例通过设置包覆结构，使得充电接口的充电负极以及参考地之间连接更加稳定。同时，由于包覆结构有导电材质构成，所以能够在大功率充电时，保证智能门锁在充电时不会出现负极被电流熔断的情况，从而保证智能门锁的正常使用。
