Accompanying drawing explanation
Can understanding feature and advantage of the present utility model clearly by reference to accompanying drawing, accompanying drawing is schematic and should not be construed as and carry out any restriction to the utility model, in the accompanying drawings:
Fig. 1 is a kind of electric supply installation circuit structure diagram that the utility model provides.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
The utility model proposes a kind of electric supply installation, as shown in Figure 1, comprising: the first power supply unit 100 and the second power supply unit 200, wherein:
The first end of the first power supply unit 100 is connected the first end P1 to form electric supply installation with the first end of the second power supply unit 200;
Second end of the first power supply unit 100 is connected the second end P2 to form electric supply installation with the second end of the second power supply unit 200.
Under normal circumstances, the first power supply unit 100 and/or the second power supply unit 200 provide electric energy for encoder for servo motor.When one of them power supply unit in the first power supply unit 100 and the second power supply unit 200 do not have the situations such as electricity, damage or loose contact cannot work power supply time, then by another power supply unit in time for encoder for servo motor is powered.
Under normal circumstances, when a power supply unit normally works, when another power supply unit does not work, this malfunctioning cells likely can charge to the power supply unit of irregular working.Such as, first power supply unit 100 normally works, second power supply unit cannot normally work because not having electricity, then the first power supply unit 100 can be that the second power supply unit 200 charges by the two ends of the first power supply unit 100, not only waste the electric energy of the first power supply unit 100, also can make the useful life of reduction by first power supply unit 100.For this reason, in the utility model, the vibrational power flow of the first power supply unit 100 and the second power supply unit is as follows:
First power supply unit 100 comprises the first battery B1 and the first diode D1.The negative pole of the first battery B1 connects the second end P2 of electric supply installation, and the positive pole of the first battery B1 connects the negative electrode of the first diode D1; The anode of the first diode D1 connects the first end P1 of electric supply installation.
Second power supply unit 200 comprises the second battery B2 and the second diode D2, wherein:
