Fig. 3 is the structural representation of the DC/DC adapter of the utility model embodiment.

Embodiment

Also in conjunction with the accompanying drawings the utility model is described in further details below by concrete execution mode.

The battery component of the utility model embodiment comprises battery and direct current (DC)/direct current (DC) adapter.As shown in Figure 1, described battery 1 surface is provided with the socket 13 that matches with the DC/DC adapter, is provided with the first terminal A1, the second terminal A2 and the 3rd terminal A3 in this socket.

Fig. 2 is the internal circuit configuration schematic diagram of battery 1, and as shown in Figure 2, this battery 1 comprises electric core 11 and peripheral circuit.Described peripheral circuit comprises CPU, light-emitting diode (Light EmittingDiode is called for short LED) indicating module 26, current sense resistor RS, computing amplifying unit U5.Current sense resistor RS one end links to each other with the first terminal A1, and the other end links to each other with the input of computing amplifying unit U5, and the output of computing amplifying unit U5 links to each other with CPU, and the output of described CPU links to each other with LED indicating module 26.

The negative terminal B-of electricity core 11 links to each other with the negative power supply terminal P-of battery by switch element U1, the first terminal A1 links to each other with the negative power supply terminal P-of battery by current sense resistor RS, and the first terminal A1 also links to each other with the negative terminal B-of electric core with switch element U1 by current sense resistor RS.The plus end B+ of electricity core links to each other with the second terminal A2, and the 3rd terminal A3 links to each other with the positive power supply terminal P+ of battery, and the second terminal A2 links to each other with the 3rd terminal A3.

As shown in Figure 3, the DC/DC adapter comprises first plug 21, second plug 22, connecting line 23, and described first plug 21 links to each other by connecting line 23 with second plug 22.All be respectively equipped with two terminals in first plug 21 and second plug 22, described connecting line 23 is two doublings.First plug 21 can insert in the battery 1 lip-deep socket 13, and second plug 22 can match with the DC power input mouth on the video camera fuselage, also can match with the power output terminal of the power supply adaptor of video camera.

The operation principle of battery component of the present utility model is as follows:

When needs used battery to power to video camera, in first plug, 21 insertion batteries, the 1 lip-deep socket 13 with the DC/DC adapter, second plug 22 inserted the DC power input mouth of video camera fuselages.Two terminals in first plug 21 link to each other with the first terminal A1, the second terminal A2 in the socket 13 respectively.Directly to the video camera power supply, video camera can normally use electric energy in so electric core 11 by the first terminal A1, the second terminal A2.Need not power to video camera by the positive power supply terminal P+ of battery, negative power supply terminal P-, detection terminal C.Can walk around the battery identification module of video camera like this, battery can be given the video camera normal power supply.

When needs charge the battery, first plug 21 of DC/DC adapter is inserted in the battery 1 lip-deep socket 13, two terminals in first plug 21 link to each other with the first terminal A1, the second terminal A2 in the socket 13 respectively, and second plug 22 links to each other with the power output terminal of the power supply adaptor of video camera.Cathode power supply is input to the plus end B+ of electric core 11 by the second terminal A2 like this, and negative power supply flows to battery cathode through switch element U1 again through current sense resistor RS, realizes a charge circuit.Power supply adaptor is directly given electric core 11 chargings by the first terminal A1, the second terminal A2.Thereby do not need to use special charger to charge the battery by the positive power supply terminal P+ of battery, negative power supply terminal P-, detection terminal C.Do not need battery is put on the video camera yet, on video camera, charge the battery.

Battery of the present utility model also has the charge and discharge deixis, concrete principle is as follows: when battery charges, charging current flows through when detecting resistance R S, can produce corresponding pressure drop in the above, this pressure drop will be amplified and the 19th pin that is input to CPU carries out the AD conversion by computing amplifying unit U5, CPU judges, relatively the value after the AD conversion according to the preset value in it, thereby determines that battery is whether in charging and charging capacity and drive corresponding LED light.When battery discharges, the current direction of the electric current that flows through current sense resistor RS during with charging is opposite, thereby the pressure drop that produces on current sense resistor RS is also opposite, current sense resistor RS goes up the 22nd pin that is input to CPU after the pressure drop that detects is amplified by computing amplifying unit U5 and carries out the AD conversion, CPU judges, relatively the value after the AD conversion according to the preset value in it, thereby determines that battery is whether at the capacity of discharge and discharge and drive corresponding LED light.

As shown in Figure 1, battery 1 surface also can be provided with lid 14, and described lid 14 is rotatable, when rotating to some angle, can cover socket 13, when rotating to the other angle, socket 13 just is not covered, and at this moment just first plug 21 of DC/DC adapter can be inserted in the socket 13.Design is not only attractive in appearance like this, and can avoid foreign matters such as dust, impurity to fall in the socket 13, influences the operate as normal of battery.

As shown in Figure 2, in the CPU of battery decoding software is housed, battery also is provided with the detection terminal C that links to each other with CPU, for the video camera of some low sides, just can directly use battery of the present utility model, and not need to use simultaneously battery and DC/DC adapter.

Obviously, battery component of the present utility model is not only applicable to video camera, applicable to other photographic equipments such as cameras yet.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
