The invention provides a door signboard with a three-dimensional character. The door signboard comprises a door signboard body and a three-dimensional character device capable of moving forward and backward, taking the character 'tian' as an example, the door signboard is characterized in that the door signboard body comprises a front panel, brushes, a hanging panel, steel pipes, a rear panel, a base plate and fixing rods; the three-dimensional character device capable of moving forward and backward comprises the three-dimensional character, supporting rods, a driving mechanism, a connector, guide rails and a supporting plate, the brushes are installed on the front panel and the hanging panel which make contact with the three-dimensional character, the three-dimensional character is connected with the supporting plate through the supporting rods on the back, the supporting plate is fixed to the base plate through the guide rails, a connecting rod is connected to the middle of the backof the supporting plate, the driving mechanism is arranged at the end of the connecting rod and used for driving the connecting rod to move forward and backward, the driving mechanism is fixed to therear panel, the hanging panel is located on the hollow-out part of the three-dimensional character, and the hanging panel is fixed to the base plate through the fixing rods. The door signboard is highin cleaning speed, simple in structure and low in cost.
