Also, in a state where the charging box 300 is separated from the charging connector 200, the secondary battery of the charging box 300 may continue to charge the electronic device stored therein. In this way, the electronic device stored in the charging box 300 can be continuously operated.

For example, the electronic device inside the charging box 300 may be detachably connected to the charging box 300;

or may be fixedly connected to the charging box 300.

The charging box 300 is detachably connected to the image pickup device 303, and the charging box 300 is detachably connected to the charging connector 200, so that the charging box 300 can be used as a storage device for a separate lens and also can be used for charging the separate lens. According to different application scenarios, the user can choose to replace the lens type in the charging box 300. For example, the lens is replaced by a wide-angle lens, a fisheye lens or an infrared lens. By the mode, the camera of the fatigue detection device is replaced, and the adaptability of the fatigue detection device is improved.

In addition, the mode of detachable connection of the charging box 300 and the camera device 303 can realize more convenient storage and use of the separated lens, and the controllability of the separated lens is improved.

For example, support piece 400 is hollow structure, and the wiring that can be more convenient like this avoids the charging wire suspension in driving space, and the interference user drives.

For example, one end of the support 400 is rotatably connected to the base 500, and the other end of the support 400 is rotatably connected to the charging connector 200. By the mode, the camera shooting angle of the camera shooting device 303 can be further adjusted, so that the fatigue detection device can be better aligned with the eyes of a user, and the defect that the fatigue detection device needs to be reinstalled after the user is replaced or the user adjusts the position of the driving seat is avoided.

In one embodiment of the present application, as shown in fig. 2, the charging connector 200 has a slot 201. The charging cartridge 300 is detachably disposed in the groove 201.
