Embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
See also illustrated in figures 1 and 2ly, in the battery of mobile phone box of the prior art, only have the metal contact of battery of mobile phone, do not supply the battery powered parts of other types, simultaneously, for bonnet, also be complete, its shape is corresponding to the shape of whole battery of mobile phone box.
See also Fig. 3 and shown in Figure 4 again; this can use the electricity supply system for mobile phone and the battery case of disposable battery; comprise the battery case on the mobile phone box body; the bonnet baffle plate; battery of mobile phone and inner power supply circuits plate; wherein; be installed on the disposable battery contact flat spring respectively on two opposite side of the side in the described battery case; also include the disposable battery voltage conversion circuit on the power supply circuits plate of this mobile phone inside; this can use the electricity supply system for mobile phone of disposable battery and the disposable battery voltage conversion circuit of battery case to comprise boost a feedback circuit and a protective circuit; described contact flat spring is connected with the both positive and negative polarity of this feedback circuit that boosts respectively; and the minus earth of this feedback circuit that boosts, described protective circuit cross-over connection is in parallel between the output of this feedback circuit that boosts and ground and with the operating handset circuit.For the battery of wherein being packed into, can be No. 5 batteries, also No. 7 batteries not, voltage is 1.2V～1.5V, simultaneously, the output voltage of this disposable battery change-over circuit is 4V～4.5V, is complementary with the operating voltage of this mobile phone.
The foregoing circuit design is fairly simple, and device is less, is beneficial to be incorporated on most of mobile phone.
See also Fig. 5 again to shown in Figure 7, because the lithium battery that mobile phone is used is different with disposable battery thickness, correspondingly, this can use on the bonnet baffle plate of the electricity supply system for mobile phone of disposable battery and battery case has and the corresponding vacancy of battery profile with the corresponding position of disposable battery, be pasted with on the adjacent one side of described battery of mobile phone with the bonnet baffle plate one with the overhead phase shortage of bonnet baffle plate with baffle plate, this baffle plate and described bonnet baffle plate piece together complete battery of mobile phone box bonnet jointly.When battery case that uses improved and baffle plate, can under the situation that does not change battery of mobile phone box thickness, use thicker disposable battery (a part of cell thickness is exposed), can improve the outward appearance of complete machine.
In the middle of reality was used, the utility model design only need increase a little IC and several resistance capacitor device on original circuit board of mobile phone, the improvement battery case just can be realized.When cell-phone battery electric-charge quantity exhausts, pull down internal battery, can change disposable battery (model can be selected No. 7 or No. 5 disposable batteries according to mobile phone profile size), continue to use mobile phone (looking the decision of disposable battery electric weight size service time).And disposable battery is seen everywhere on market, thereby the practical application of this patent is very extensive, and feasibility is also very high.
This utility model designs not only applicable to most mobile phones, and can be applied on other carry-on digital product that uses built-in rechargeable battery.
The electricity supply system for mobile phone and the battery case of the used disposable battery of above design have been adopted, owing to have the disposable battery voltage conversion circuit in this mobile phone circuit, coupled disposable battery contact flat spring is also arranged in battery case simultaneously, make when cell-phone battery electric-charge quantity exhausts, pull down internal battery, can change disposable battery (model can be selected No. 7 or No. 5 disposable batteries according to mobile phone profile size), continue to use mobile phone (looking the decision of disposable battery electric weight size service time); Simultaneously, this utility model simple in structure, it is quick to be easy to use, and the scope of application is wider.
In this specification, the utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
