[0095] In this embodiment, the door body 20 rotates around a preset axis between an open position and a closed position. When the door body 20 is in the open position, the door body 20 is in an open state; when the door body 20 is in the closed position, the door body 20 is in a closed state. Along the opening and closing path of the door body 20, the door body 20 has a preset position between the open position and the closed position of the door body 20.

[0096] The depth direction of the box body 10 is perpendicular to the plane where the preset opening 11 is located. In the depth direction of the box body 10 , the inner wall surface of the box body 10 arranged opposite to the preset opening 11 is the bottom wall of the box body 10 .

[0097] When the door body 20 is between the preset position and the closed position, along the depth direction of the box body 10, the second end of the power member 31 is located on the side of the bottom wall of the box body 10 close to its first end; when the door body 20 is between the preset position and the open position, along the depth direction of the box body 10, the first end of the power member 31 is located on the side of the bottom wall of the box body 10 close to its second end.

[0098] Specifically, along the depth direction of the box body 10 , the side close to the bottom wall of the box body 10 is the rear side, and the side away from the bottom wall of the box body 10 is the front side.

[0099] During the specific implementation, when the door body 20 is in a closed state, in the depth direction of the box body 10, the rotation axis B of the first end of the power member 31 is in front of the rotation axis A of the second end of the power member 31. During the closing process of the door body 20, in the depth direction of the box body 10, in the initial stage (the door body 20 is between the open position and the preset position), the rotation axis B of the first end of the power member 31 is behind the rotation axis A of the second end of the power member 31, the force direction of the power member 31 acting on the door body 20 is toward the front side, and the door body 20 has a tendency to move forward; the door body 20 continues to close, the rotation axis B of the first end of the power member 31 is in front of the rotation axis A of the second end of the power member 31, the force direction of the power member 31 acting on the door body 20 is toward the rear side, and the door body 20 has a tendency to move backward. At this time, the door body 20 will automatically close and will not bounce up, realizing automatic adsorption when closing the door.

[0100] During the process of opening the door body 20, in the depth direction of the box body 10, in the initial stage (the door body 20 is between the closed position and the preset position), the first end rotation axis B of the power member 31 is in front of the second end rotation axis A of the power member 31, and the direction of the component force of the power member 31 acting on the door body 20 is toward the rear side, and the door body 20 has a tendency to move backward. Therefore, when the door body 20 is opened, due to the self-adsorption effect of the door body 20, the door body 20 will not immediately bounce up and cause safety risks; continue to open the door body 20, the second end rotation axis A of the power member 31 will slowly exceed the first end rotation axis B of the power member 31, and the direction of the component force of the power member 31 acting on the door body 20 will change to be toward the front side, and the component force of the power member 31 acting on the door body 20 will slowly increase with the increase of the door opening angle, thereby realizing slow opening and preventing personnel from having difficulty in operating due to excessive component force acting on the door body 20 during the process of opening the door body 20.

[0101] The box structure of the present application utilizes the component force of the power member 31 acting on the door body 20 to achieve automatic adsorption of the door body 20 when closing and opening. When closing the door body 20, when the door body 20 is closed to the rear side of the rotation axis B of the first end of the power member 31 and the rotation axis A of the second end of the power member 31, the door body 20 automatically closes. When opening the door body 20, the door body 20 will not bounce up immediately, avoiding the occurrence of dangerous accidents. As the opening angle of the door body 20 changes, the force on the door body 20 changes to the front side, and at this time, the component force of the power member 31 acting on the door body 20 will slowly increase as the door opening angle increases, achieving slow opening, and preventing personnel from having difficulty in operating the door body 20 due to excessive component force acting on the door body 20 during the process of opening the door body 20. The box structure of the present application solves the problems of difficult and dangerous front door operation of existing outdoor boxes.
