Abstract
The utility model relates to door box equipment which can realize full-angle automatic door opening and closing and improve user experience. The door box device comprises a box body frame; the door body assembly comprises a door main body, a linear driving mechanism mounted on the door main body and a balancing weight which is arranged on the door main body in a sliding manner and is in driving connection with the linear driving mechanism; the hinge spring assembly comprises a hinge assembly, a pull rope and a spring, the hinge assembly enables the door body assembly to be rotatably installed on the box body frame, the pull rope is connected with the door body assembly, the spring is connected with the box body frame, and the spring is connected to the pull rope and used for applying tension moment opposite to the gravity moment of the door body assembly to the door body assembly; when the balancing weight is driven by the linear driving mechanism to slide relative to the door body, the gravity center position of the door body assembly is adjusted, so that the gravity moment of the door body assembly is larger than, equal to or smaller than the tension moment applied to the door body assembly by the hinge spring assembly.
