Embodiment
To combine accompanying drawing and specific embodiment to do further explanation below to of the present invention.
Remote control holder is shown in Figure 1, and Fig. 1 is the structure of a kind of wall-hanging remote control holder and chargeable remote controller, and it can directly be inserted on the wall socket through plug 1 and use.In the carriage indoor design slot 4, it can place 1 remote controller 2, includes charging circuit in the bracket base.The carriage side is furnished with LED light 3, can supply night and do the low-light illumination.
Fig. 2 is the structure of a kind of desk-top remote control holder and chargeable remote controller, and how it can be positioned over and use on the platform, bracket design the slot of a plurality of depressions; Can place many remote controllers 2; As signal, only draw two among the figure, included charging circuit in the bracket base.The carriage side is furnished with LED light 3, can supply night and do the low-light illumination.
As shown in Figure 3; For guaranteeing conveniently to charge, two metal electrodes 6 that have support spring have been designed among Fig. 1 and Fig. 2 in the remote control holder slot, when remote controller inserts in slot; Metal electrode just can closely contact with two electrodes of remote controller, thereby charges reliably.
Fig. 4 is the block diagram of charging circuit; It comprises that AC/DC (exchange conversion direct current) circuit 7, two formula voltage controllers 11 and control constant-current circuit module 10 form; Said two formula voltage controllers 11 comprise first comparator, second comparator and rest-set flip-flop; The output of said first comparator and said second comparator is imported with S with the R input of said rest-set flip-flop respectively and is connected; The output of said rest-set flip-flop links to each other with control constant-current circuit module; The output of said control constant-current circuit module 10 connects the positive terminal and the said second comparator negative pole end of said first comparator, and said interchange conversion DC circuit 7 outputs connect the output of said control constant-current circuit module 10 through 100 kilo-ohms of resistance 8; Circuit charges through the 9 pairs of storage batterys in charging end, and the negative pole end of said first comparator connects the height that is provided with pressures of rationing the power supply, and the positive terminal of said second comparator connects the lowest limit voltage of setting.
