DAVIES COLLISON CAVE Patent Trade Mark Attorneys Level 10, 10 Barrack Street SYDNEY NSW 2000 AC/DC Rechargeable mobile phone cell The following statement is a full description of this invention, including the best method of performing it known to me:- 5028 1a-xplanations on the Creation: :Backgoun of the Creation [A Brief mtrrjduiijO. on the Creation Technologyj -c l Thic catin i a ki d o "A Crechargeable m obile Phone cell-, especially a mnobile phon cel wichcanbe charged directly by market Power Or chbarged by an ordinary DC charger available on the mnarket ~TO charge a traditionmal mobile phone cell forrpeihn h osmdee~acagrms 0.0 beuse F r t is eas n, he serhato buy an etra charger' and Pay more m oney Besides, the charger is too large and too heavy and cumbersome to Carry.
:00 [A BriefLADtz4(Ctrj on on Former Tecl ogy Bec a g a u se o fe t hs e d s d n t g t h m a n u f a c t u r e r s h a v e i p r o v e d i t A s s h o w n i n F g 1 t h e recargabl ce1 is composed of a case(Ic)) and a charger etc.. A Concave cabinet (13) with two notches on its left and right is Placed on the panel (12) of the case (10) to- hold an eversible and locatable Plug The phmg15) has two forward stec del tici etin icsl6 ada Conductng Suppr axle(l 7) connecting the electric inrthdeti sertion Pieces(l6 6)vre.Lf and ih conducting plates(l 8) With notches are installed on the circuit board(l 1) of the charger to grip thle conducting support axle(l?7) of the plug Then the market POwer(AC) can be Supplied into the hrge through the electric insertion piecesO conducting Support axe(l 7) and conducting plate( 18) Of the plug(l5). But this design of the conducting support axle(I 7) wiln inicrease current resstac; in addition, the contacts -between the conducting support axle(l 7) and the conducting plates(l 8) of the circuit board(l 1) is in fast Coupling form, which cannot be firmaly contacte& Besides, when the plug(l 5) .is everting and locating as well as retractin and settling the -2conducting support axle(17) is not detached from the conducting it always courses abrasion and result in loweg conductivity. Eva conducting plate(18), it always courses abrasion and result in lowering conductivity. Even more, because the positioning of the conducting support axle(17) of the plug (15) is basedon the firm assembly of the cit board( the and the supporting of the conducting plate(18), looses always occur. This is not an ideal structure for operation.
Another shortcoming is: Plug(15) is the AC input terminal of the charger. After rectifying, filtering and stabilizng, the AC is converted into DC to drive the tranformer and charging circuit through a driving circuit composed of transistors. he DC, on the one hand, is used to charge the rechargeable cell(19), on the other hand, supplies energy to the mobile phone through the DC output terminals of the panel(12). When the cells(19) are full charged, the charger cannot shut down the driven circuit automatically. It will result m energy wasting and life-time shortening of the circuit and cells(9). Another problem is that there is no indicator for full charging and no overheating protection for the cells(1 9).
SBecause of the disadvantages of the existed rechargeable mobile phone cell, I have been looking for a new way to solve these problems and finally completed the creation
"AC/DC
rechargeable mobile phone cell".
The purpose of this creation is to provide an "AC/DC rechargeable mobile phone cell". Its S: plastic axle of the plug is held between the concave cabinet of the panel and back ase body, making plug's electric insen iece to press lose on the elastic conducting pieces of the charger circuit board. When the plug is retracted and settled, the electric insertion pieces will be detached from the elastic conducting pieces. It can be fast and firmly assembled as a whole. It is durable and its conducting quality is improved.
Another pupose of this creation is to provide'an "AC/DC rechargeable mobile phone cell". An eversible and locatable plug is placed on the back of the case body, making the rechargeable cell can be directly charged by the market power without detaching from the mobile phone.
.The third purpose of the creation is to provide an "AC/DC rechargeable mobile phone cell". A S dual-color LED, a theral sensitive resistor and the echargeable cells are connected parallel across the charging circuit. When the charging voltage is lower then the reference voltage, the red light of the dual LED is lit up. When the cells are fully charged, the green light of the dual LED is lit up and a low potential is output to an optic-coupling switch from a linear IC to stop recharging.
Accordingly, the energy is saved and the cell's life is prolonged For the purpose of appraisal, a practical example with pictures is introduced in detail as follows to explain how to realize the above target by using technology measures.

A charger is fixed in a case, and a concave cabinet (22) space is formed on the front of the panel(20) of the case to hold the plug (30) can be everted and located as well as retracted and Ssettled) which is used for directly charging with the market power.
As indicated in Fig.3, the case of the rechargeable cell is composed of the panel(20) and back case body(21) by connecting them with high-frequency fusion jointing. A concave cabinet(22) space is made on the front of the panel(20). notches (25) are made respectively at the rear ends of the left and right side walls(23X24) of the concave cabinet(22) to fit the left and right sections of the plastic support axle(32X33) of the plastic body(31) of the plug(30). The left and right electric insertion pieces(34X35) of the plug run through the plastic body(31) (longer in front, shorter in rear). A pair of plastic supporting plates(26X27) are placed on the inner side of the back case body oppositely each other with one on the left, the other on the right. The plastic supporting plates grip the supporting axle(32X33) of the plug with their notches(28) located at the front end of the plates to enable the plug(30) can be everted and located or retracted and settled around the axle.
The charger circuit board(50) and rechargeable cells(67) are firmly installed in the case of the rechargeable cell. Two elastic conducting pieces(51 X52) stretch out of the circuit board (50) are used as AC input terminals. The rear ends of the electric insertion pieces(34)(35) of the are elastically pressed on the pieces(51)(52) Fig.4,5,6 show that the plug(30) is in everted and located position. The plastic body (31) of the plug 3 0)matches the left and right wals(23X24) of the concave cabinet(22). The plastic supporting axle(32)(33) is gripped and held by a supporting -4plate(26X27) and its notches(25X28) with the same material. This method can reduce electrical resistance, improve current conducting quality, as a result, the AC current can run into the charger through the electric insertion pieces(34X35) of the plug(30) and elastic conducting pieces(51X52) smoothly. In addition, it is durable and can be assembled fast and firmly.
As indicated in Fig.7, when the rechargeable cell needs not to be charged, you may retract and settle the plug(30) into the concave cabinet(22) space of the panel then the rear ends of the electric insertion pieces(34)(35) of the plug(30) will detached from the elastic conducting pieces(51 X52) of the circuit As indicated in Fig.8, AC110-240V power enters the AC input tenninal(60) of the rechargeable cell, and then goes through the rectifying circuit(61), filtering circuit(62) voltage stabilizing circuit(63), driving circuit(64) and charging circuit(65) to charge the rechargeable cells(67). When using market charger, the charging current runs through the DC terminal(69) and elastic charging piece(42) as indicated in Fig.3) into rechargeable cells(67). When the rechargeable cells are fully charged, you may switch the DC into the mobile phone through its DC output terminal (68) and the conducting piece(40) as indicated in Fig.3.
4.
Please refer to Fig. 9: The AC 110-240V power enters the AC input tenninal(60) of the charger, then rectified into DC current through a bridge connected rectifier (Dl) of the rectifying circuit(61). The current limiting resistor(R1) is used to limit the current within a definitive range; the resistor(R2) and diode(D2) combined with the transistor(Ql) are used as a filter, and together with a Zener diode(D3) in the voltage stabilizing circuit provide a comparing reference voltage for the over current protection section in the driving circuit A switching circuit, which provides a proper voltage to control the transistor(Q2), is composed of a transistor(Ql) and an optical coupler(E1). The rechargeable cells(67) are charged through the transformer(T) and charging circuit(65). The charging circuit(65) is connected to the output terminal of the transformer's secondary coil. The following elements are connected in the charging circuit(65) paralelly: a dual color LED, a capacitor(E4) serially connected with a diode(D4), and the rechargeable cells(67). Through a Zener diode (D5) and resistor a linear IC(E2) is connected at the connecting point of the capacitor(C4) and diode(D4) to provide a reference voltage. Another end of the linear IC(E2) is connected to the cross-over point of the dual color LED to compare the charging voltage with the reference voltage. While the voltage is lower than the reference voltage (the potential of pin #3 lower than that of pin the driving circui(64) is driven to work, and the rechargeable cels(67) is charged through the transformer(T) and the charging circuit(65). At the same time, the dual color LED (refer to the light window(29) in Fig.3) is lit up with red color, showing it is charging. When the rechargeable cells are fully charged the potential of pin #2 lower than that of pin the diode(D4) is conducted and the dual LED is lit up with green color. At the same time, a lower potential is output to the optical switch IC(E1) from the linear IC(E2) to cut-off the transistor(Q2) and stop charging. As a result, the energy is saved and the life of the circuit and cells is prolonged.
Before the rechargeable cells(67) is connected to the output terminals of the transformer(T)'s secondary side, two thermal sensitive resistors (RIO),(RII) of an over-heating protection circuit(66) are serially connected with it. While the temperature inside the rechargeable cell(67) is rising, the resistance of the thermal sensitive resistors (RIO), (RII) is going down correspondingly, which provides an over-heating protection to stop charging the rechargeable cells.
As indicated in Fig. 10, the concave cabinet(220) is placed on the back of the case(210) to hold the plug(30) making the rechargeable cell to be charged by the market power without detaching it from the mobile phone.
In summary, the AC/DC rechargeable mobile phone cell" is durable and can be assembled fast and firmly; its conductivity is higher than the others; suitable for charging a standby mobile phone; it has indicators for displaying the charging conditions (charging or fully charged); it can stop charging automatically, as a result, the life-time of the circuits and rechargeable cells are prolonged. It can meet all requirements in practice. I hereby submit the application for a New Type Patent.
