Abstract

The utility model relates to a rechargeable battery for mobile phones, which is composed of a battery case, a rechargeable battery, a charging unit, a displayer and an interface portion. The casing is provided with small grooves which enable the electrodes in the interface portion to be horizontally placed. The interface portion is composed of connecting electrodes, rotary nuts, charging electrodes and charging interfaces. The interfaces are designed not to occupy any space in the casing of the battery, so that the charging unit and the battery are combined into integration. The utility model has the advantages of compact structure, convenient operation, etc., and is suitable for various mobile phones.

Description

The chargeable battery of mobile telephone

The utility model belongs to the rechargeable battery field.

At present, mobile phone person who want to call scope of activities is big, and movable random is strong, but battery of mobile telephone is very short discharge time, need use extremely inconvenient with the huge charger of upper volume when the machine of particularly taking is gone on business.The present interfaces technology is bigger because of electrode takes up space, and can't directly apply to charger, as Chinese patent variable angle plug ZL94808797.6.

It is collapsible that the purpose of this utility model provides a kind of electrode, compact conformation, chargeable battery of mobile telephone easy to use.

The purpose of this utility model is achieved in that a kind of chargeable battery of mobile telephone, it comprises battery injection casing 1, chargeable battery 2, charhing unit 4, display composition, its primary structure is that charhing unit 4 is made up of charging circuit, charging circuit is connected with the interface section, and sulculus 3 is set on the housing; The interface section is made up of connection electrode 8, the nut 10 that spins, charging electrode 5, charging inlet 6; Charging inlet 6 is connected with outer casing bottom sulculus 3, and charging electrode 5 can pass charging inlet 6, and the nut 10 that spins presses electrode and is connected as a single entity with charging inlet 6, and securing member 9 makes connection electrode 8 be connected with shell 1 bottom, and connection electrode 8 is connected with the nut 10 that spins simultaneously; Electrode 5 can be flat in the sulculus 3 and isoplanar, shell 1 bottom.

The electrode of this chargeable battery of mobile telephone, charging inlet, the nut that spins, connection electrode are that copper material is made; Electrode, connection electrode form sheet; Charging circuit is made up of alternating voltage circuit, snowslide trigger, chargeable battery, and the alternating voltage circuit is by inductance L and parallel resistor R ₁And capacitor C ₁Be composed in series, by resistance R ₂, capacitor C ₂And transistor T constitutes snowslide trigger and resistance R ₁And capacitor C ₁Connect, transistor T is connected with controllable silicon SCR, diode D ₁Be connected current-limiting resistance R after the controllable silicon SCR parallel connection with chargeable battery ₃Be connected with alternating voltage circuit, chargeable battery.

Owing to adopt interface section described in the utility model, it can be in the horizontal direction or vertical direction rotation or translation-angle, make charging inlet not take battery space, put into housing after the while charging electrode is collapsible, do not take the outside batteries space, therefore has compact conformation, characteristics such as easy to use.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a plane graph of the present utility model;

Fig. 2 is the end view of Fig. 1;

Fig. 3 is the charging circuit schematic diagram;

Fig. 4 is the interface section schematic diagram;

Fig. 5 is the charging inlet plane graph;

Fig. 6 is interface closed condition figure;

Fig. 7-9 is to use state reference map.

Among the figure: 1, shell, 2, chargeable battery, 3, sulculus, 4, constant current charge unit fast, 5, the charging electrode sheet, 6, charging inlet, 7, display, 8, connection electrode, 9, the securing member screw, 10, nut spins.

Be that example is illustrated now with regard to the MOTOROLA9900X battery of mobile telephone:

Dotted line rectifies 2 for the shared volume of chargeable battery, and dotted line is rectified and 4 is quick constant current charge unit, and its circuit theory is seen Fig. 3, among Fig. 3 alternating current through inductance L, resistance R ₁And capacitor C ₁, a point produces 15V left and right sides alternating voltage.By resistance R ₂, capacitor C ₂And the transistor ec utmost point constitutes a snowslide trigger.SCR ends D during the positive half cycle of alternating current ₁Conducting is through resistance R ₃After the current limliting nickel-cadmium cell is charged.Work as capacitor C ₂Both end voltage rises to T ₁During avalanche voltage, the SCR conducting that is triggered forms battery is sparked, 6 is charging inlet among Fig. 1, this is this design key, here will have patent ZL94208797.6 technology and be improved, the electrode slice decapacitation is rotated freely in the horizontal direction with outside the adaptive various low capacity standard sockets, also can change an angle of 90 degrees in vertical direction, thereby make its charging inlet not take space in the very crowded box, and make this space hold charhing unit to become possibility.Its function and operating principle are seen Fig. 6-9, and wherein Fig. 6 is the interface closed condition, and this moment, interface 6 became cheek with electrode slice 5 with outer casing bottom, was convenient to battery and conveniently snapped in phone, did not take the shell inner volume simultaneously.For opening interface, electrode slice 5 vertical shell planes 90 are spent among Fig. 7.After it is vertical, can click gently again, electrode slice is promptly to a bit of distance b of interface 6 groove displacements, electrode slice was lockable in vertical direction and can not returns on Fig. 6 state again this moment, electrode slice 5 is revolved towards Fig. 8 direction of arrow to be turn 90 degrees or towards Fig. 9 direction of arrow rotation 30 degree, gets final product on the various low capacity standard electric alternating current of the adaptive insertion socket and charge.Owing to reveal on the original-pack battery case of MOTOROLA9900X phone the charging inlet electrode arranged, and the design inserts one and moulds the system insulation board to guarantee that contacting this place because of carelessness when filling causes accident, can mould this plate extraction in the time of need charge on charger at former interface position.3 sulculuses that design when the shell injection molded among Fig. 1 both can conveniently be opened interface with finger, again just during down interface electrode slice with locate the shell bottom and keep the plane.7 is display among Fig. 1, extinguishes after the battery abundance, with prompting electric energy abundance.Be the electrode that is slidingly connected among Fig. 1,4A, 4B are connected on respectively on this two electrode among Fig. 3.Fig. 4 is the interface part drawing, is the plastics except that shell 1 among this figure, and other part is made for brass material entirely, and charging inlet 6 can be done chromium plating and handle, but electrode slice 5 nickel plating, but rotatably compress also nickel plating of nut 10.

This design is applicable to all kinds of battery of mobile telephone.
