This not only further facilitates the user to use, but also, there may be high voltage in the photovoltaic intelligent busbar box 10, which is relatively dangerous. With such a setting, as long as the user slightly flips the front panel 117, the front panel 117 can automatically cover the opening of the surrounding frame 116, and the chassis 1 can be automatically locked, thus effectively preventing the user from forgetting to close the photovoltaic intelligent busbar box 10, and further preventing non-professionals or animals from opening the photovoltaic intelligent busbar box 10 and accidentally touching it, resulting in safety accidents.
