The transmission control mode of the control motor 321 and the gear 322 has high control precision and can accurately control the moving position of the roller shutter 31. Alternatively, the control structure 32 can be provided with only one gear 322, and the gear 322 is directly sleeved on the output shaft of the control motor 321 and cooperates with the roller shutter 31, thereby reducing the number of parts in the detection assembly 100, simplifying the structure of the detection assembly 100, and being beneficial to reduce the volume of the detection assembly 100.
