DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
20 The electric device of the present invention comprises mobile phones, wireless intercoms, notebook computers, personal digital assistants, flashlights, digital cameras, charger bases, etc. In the following, the mobile phone is used as an example for description.
Referring to Figs. 1 and 3, the exploded perspective views of a mobile phones and standby battery from different views are illustrated. A mobile phone 10 and a standby battery 20 are 25 illustrated in the drawings The backside of the mobile phone 10 has a groove 11 for installing a standby battery 20 having the same area. The standby battery 20 is formed by a housing 21 and a
plurality of cells 22, 23 fixed to the housing 21. An upper end of the housing 21 has an upper buckle 211 which can be buckled with an upper buckling groove 01 at an upper end of the groove 11, and a lower end thereof has a lower buckle 212 which can be buckled with a lower buckling groove 102 at an lower end of the groove 11. An interior of the housing 21 is a hollow groove S 213 for receiving the cells 22, 23 An upper end of each cell has two metal joints 221, 231 When the metal joints are aligned with and in contact with two conductive joints 12 in the groove 11 of the mobile phone 10, power can be inputted input the mobile phone 10 Fig. 2 shows that the mobile phone 10 is assembled with the standby battery 20 When the cell 22 is a main cell, as the energy is exhausted, it is only necessary to exchange 1 0 the cells 22, 23. Then, the standby battery 20 can be used as a main cell to supply power to the mobile phone 10 After the cells 22, 23 are exchanged, it is necessary to supply power to the main battery 22 as early as possible After the power of the standby battery 23 is exhausted, then the two cells 22, 23 are exchanged. Then the main cell 22 is utilized to supply power.
Fig 4 shows an exploded perspective view of a mobile phone and a standby battery. It is 15 illustrated that the difference of the standby battery 20 with abovesaid one is a circuit board 24 being installed at an inner surface of the housing 21 The circuit board 24 has four metal pieces 241, 242 which are divided into two sets and can contact the two metal joints 221, 231. Two metal pieces 243 exposes from an upper end of the housing 21 for being in contact with the two conductive joints l 2 of the mobile phone 10 (referring to Fig. 5). In Fig. 5, it is illustrated that the 20 back side of the housing 21 is installed with a switch 25 By the switch 5, one cell is selected The switch circuit may be understood from Fig. 6 Fig. 7 is a perspective view of another battery. It is illustrated that the two cells 22, 23 of the standby battery 20 are placed oppositely Namely, the metal terminals 221, 231 of the two cells 22, 23 are not the same end.
25 Fig. 8 illustrates that the metal terminals 231 of the cell 23 in the standby battery 20 may contact the conductive joint 12 of the mobile phone 10. When the power of the battery 23 is
/ - exhausted, the battery 20 can be rotated through 180 degrees so as to be installed at a backside of the mobile phone 10, as illustrated in Fig. 9. Now, power ofthe mobile phone 10 is from the cell 22. Next, the number of cells in the battery 20 may be larger than 2. For example, as illustrated 5 in Fig. 10, a housing 21 is used with four cells 22,23,22', 23'.
The battery 20 can be arranged longitudinally or transversally For example, the two cells 22, 23 in Fig. 11 are transversally arranged.
Furthermore, the housing 21 has box having a groove-like shape with four enclosing sides.
Two lateral frames 214 are used to prevent the cells from moving out of the housing.
10 Referring to Fig. 13, in battery 20, the cells 22,23 are enclosed in the housing 21, and are arranged oppositely. Only metal terminals 221,231 are exposed on the surface ofthe housing 21.
Moreover, in Fig. 14, the battery 20 has two cells 22, 23 which are used with the mobile phone 10 without any housing 21. Moreover, the mobile phone 10 must have an upper and a lower buckling groove 101, 102 serving to match the upper and lower buckling blocks 222,223, 15 232,233 of the two cells 22,23. Therefore, it is known that there are many ways for embodying the standby battery ofthe present invention.
Similarly, the standby battery can be used at other portable devices. For example, Fig. 15 shows an assembled perspective view of a standby battery 20 and a wireless intercom 30. In the figure, two cells 22,23 may be embedded into the embedding groove 31 of the wireless intercom 20 Similarly, Fig. 16 shows that the standby battery 20 can be embedded into the embedding groove 41 of a notebook computer 40.
Similarly, Fig. 17 illustrates that the standby battery 20 can be embedded into an embedding groove 51 of a palm top processor 50.
Similarly, Fig. 18 discloses that the standby battery 20 can be embedded into an embedding 25 groove 61 of a charger base 60. Furthermore, the present invention can be used in a flashlight, digital cameras, and other portable devices.
s
Fig. 19 shows a chargeable standby battery 20. A charging circuit (for example, Fig. 20) is installed between the two cells 22, 23. The two cells 22, 23 are disposed oppositely, and therefore, the metal joints 221, 231 are installed at different ends. In this circuit' a diode D1 is run across two battery spaces. Therefore, power of the cell 22 may flow into the cell 23, while the power of 5 the cell 23 cannot flow into the cell 22. By this property, when power of the cell 22 is exhausted.
The battery 20 can be reversely arranged for using power of the battery 23. When it is necessary to supply power' it is only necessary to insert a charging head 30 into the charging groove 103 of the mobile phone 10. Then power will supply to cell 22 at first, and then the power flows through the diode D1 to supply cell 23. The operation is convenient and usable 10 Fig. 21 shows a chargeable standby battery 20. After matching with a mobile phone 10, by the charging head 30 pressing a microswitch 40 at a lateral side of the charging groove 103 in a bottom end of the mobile phone 10, power can be supplied to the two cells 22, 23. Thereby, two cells 22,23 are charged at the same time. The circuit is illustrated in Fig. 22.
Next, a boost circuit is installed in the battery 20, as shown in the Fig. 23. When the power 15 of the battery 22 is exhausted, it is only necessary to press the switch S1, then the voltage of the cell 23 can be supplied to the cell 22 so that cell 22 may work continuously to achieve the function of boosting voltage.
Fig. 24 shows that a voltage descending circuit installed in the circuit. Since a resistor R is installed therein, when the voltage of the output end is lower than a working voltage, the mobile 20 phone will thus interrupt. Now, if a switch S2 is pressed, the output of the battery has no voltage descending. Therefore, the object of supplying power is achieved.
The present invention can achieve the following results: 1. The standby battery is installed in an electric device. The user dose not worry about that the standby battery is to carried. As the power of the electric device is insufficient, the 25 standby battery can be used immediately. No signal or power interruption occur.
2. As the power of the main cell is exhausted and the standby cell is used, it is like to
inform the user to charge the cell.
3. The present invention can be used with the electric device without changing the body of the electric device.
4. The trouble that no cell is found can be avoided. The standby battery can be carried with 5 the electric device.
Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof Various substitutions and modifications have been suggested in the foregoing description,
and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and 10 modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
