[0003] The traditional car console storage box does not have a roller shutter door, or uses a manual push-pull type cover door, which is not conducive to storing goods, has low automation, and lacks a sense of technology. The existing technical improvement is mainly to optimize the appearance of the storage box and the cover door, and there are few applications for automation improvement. SUMMARY

[0007] The induction sensor is used to detect hand sweeping actions and generate a hand sweeping control signal to the controller; the photoelectric sensor is installed on the opening edge of the storage box and is used to detect whether the goods in the storage box exceed the height of the roller shutter door; the current detector is used to detect the working current value of the rudder; the controller is used to output a control signal to the rudder to control the rudder to work, and the rudder is provided with an angle encoder for detecting the real-time angle value of the rudder.

[0023] S72: whether the rudder angle value is greater than or equal to the preset maximum angle value β is judged, if yes, it is indicated that the roller shutter door has been closed to the position, the rudder is controlled to stop, and the system state is set to the first state.

[0024] Further, the following step is further included: if no, step S73 is entered;

[0025] S73: whether the rudder working current value is greater than the overrun threshold I M At the same time, whether the photoelectric sensor is blocked by an article is judged, if one of the two is yes, the rudder is controlled to stop, and the system state is set to the first state.

[0026] The technical effect of the technical scheme of the present application is that the automation of the opening and closing of the roller shutter door of the automobile center console storage box is realized, the opening or closing of the center console storage box can be controlled through hand-sweeping, and the integrated diffuse reflection photoelectric sensor and current detector realize the judgment of whether a higher object is stored in the storage box and the detection of the resistance in the movement process of the roller shutter door of the storage box, the reasonable protection of the stored object is realized, and the storage box is more intelligent, more convenient and safer.
