Utility model content
The purpose of this utility model is to provide a kind of pointer and the two aobvious electronic scaless of LCD, and this circuit structure is simple, has changed the circuit structure that existing electronic scales only possesses single demonstration.
The utility model adopts following scheme to realize: the two aobvious electronic scaless of a kind of pointer and LCD, comprise LOAD CELLS, be arranged on rotating pointer on scale panel and be the power module of electronic scales power supply, it is characterized in that: described LOAD CELLS is connected with a CPU through A/D convertor circuit; Described CPU is connected with LCD through a LCD driving circuit; Described CPU is through a stepper motor driving circuit Driving Stepping Motor, and described stepper motor is for driving the rotation of described pointer.
Further, described power module is button cell power supply or dry cell power supply power supply.
Further, the surface that described scale panel and pointer are arranged at electronic scales, described LCD is arranged at the downside of scale panel.
Further, described scale panel is limbus panel.
Further, described rotating pointer comprises a rotating shaft, and described rotating shaft upper end is provided with a pointer; The bottom of described rotating shaft is provided with one first gear, is provided with the second gear in the rotating shaft of described stepper motor, described the first gear and the engagement of the second gear.
Further, described rotating pointer comprises a rotating shaft, and described rotating shaft upper end is provided with a transparent disc, and the edge of described disk is fixed with a pointer; The bottom of described rotating shaft is provided with one first gear, is provided with the second gear in the rotating shaft of described stepper motor, described the first gear and the engagement of the second gear.
Further, described rotating shaft is hollow axle, and described CPU is also connected with model selection key circuit, infrared circuit and warning circuit, and the detection probe of described infrared circuit is arranged in described hollow axle; On the rear panel of described electronic scales, be provided with a bracing frame.
The utility model not only possesses two Presentation Functions, and pointer shows it is to rotate by stepper motor drive finger, thereby realizes indication, has changed in the past by elastic deformation the drawback that rotation scale shows.And the utility model can also serve as warning device when not using, realize one-object-many-purposes.
