Description
Technical field
The present invention is a kind of mobile telephone cell charging device, refers to a kind of charging device that makes two mobile phones directly carry out electric power transfer especially.
Background technology
Along with the utilization rate of mobile phone is universal day by day, an a large amount of use mobile phone of working clan of economic capability is not only had in China now, even if the student also enters the epoch of everyone mobile phone already.Yet along with the dependence to mobile phone is deepened day by day, people also are more and more high to the requirement of mobile phone function.
Wherein, make us most one of the problem be concerned about, be the charging problem of mobile phone.No matter the charger of mobile phone is that formula is filled in so-called charging or trip at present, all is after mobile phone is connected to an adapter (Adaptor), and the plug by adapter inserts supply socket again, to charge.But because the call volume of modern's mobile phone is more and more big, and the charge capacity of existing mobile telephone cell is not as desirable, mobile phone just taking place often converse to half and just do not have electricity, but can not find the awkward situation that supply socket is charged for the moment, reduces the original idea of mobile phone convenience.
Summary of the invention
Main purpose of the present invention is the built-in charging device of phone in action, connect two mobile phones by a transmission line after, two mobile phones can directly be carried out electric power transfer.
Mobile telephone cell charging device of the present invention connects two mobile phones by a transmission line, and to carry out electric power transfer, wherein this action phone includes: a transmission of electricity groove, and it is arranged on the body of mobile phone, in order to connect outside transmission line; One is connected to the charging device of mobile telephone cell, this charging device is connected to above-mentioned transmission of electricity groove, insert the transmission of electricity groove of two mobile phones respectively by this transmission line, after forming being electrically connected of two mobile phones, can carry out the electric power transfer between two mobile phones, and this action telephone cells be charged by this charging device.
Mobile telephone cell charging device of the present invention is controlled electric power transfer amount and electric power transfer time between two mobile phones by the control unit adjustment; utilize the thermoinduction technology by protected location simultaneously; to prevent that mobile telephone cell from damaging the inside battery structure because of overcharging, cause the distortion of battery stamen, leakage even blast etc.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the another embodiment of the present invention schematic diagram.
Embodiment
See also shown in Figure 1, be structural representation of the present invention, as shown in the figure: mobile telephone cell charging device of the present invention, be to have a charging device 12 that is connected to mobile telephone cell 11 in action in the phone 1, this charging device 12 is connected with a transmission of electricity groove 13, behind this transmission of electricity groove 13 of a transmission line 3 insertions, and be connected to another mobile phone 2, to carry out the electric power transfer of 1,2 of this two mobile phones.
Above-mentioned charging device 12 is made up of a control unit 14 and a protected location 15; This control unit 14 is in order to the amount of inputing or outputing of control battery 11 electric power; 15 of this protected locations because of the input too high voltages, and destroy battery 11 internal structures in order to the battery 11 that prevents mobile phone 1, as cause battery 11 battery stamen distortion, leakage even blast etc.
This battery 11 can be nickel-cadmium cell, Ni-MH battery, lithium battery or plants secondary battery (being storage battery) arbitrarily, and with lithium battery as preferred embodiment, because of lithium battery has that discharge voltage is stable, operating temperature range is wide, self-discharge rate is low, storage life is long and memory-less effect and advantage such as nuisanceless.
This groove 13 of transmitting electricity is arranged on the body of mobile phone 1, in order to connect outside transmission line 3.
Mobile telephone cell charging device of the present invention; its operation principle is to utilize a transmission line 3 to insert the transmission of electricity groove 13 of two mobile phones 1,2 respectively; after forming being electrically connected of two mobile phones 1,2; adjust the electric power transfer amount of 1,2 of control two mobile phones by above-mentioned control unit 14; pass through this protected location 15 simultaneously when battery 11 chargings are complete; promptly cut off electric power transfer, avoid battery 11 to cause battery 11 internal structures to damage the useful life that shortens battery 11 because of overcharging.
Except that the electric power transfer amount that can adjust 1,2 of two mobile phones of control, also may command two mobile phones 1,2 electric power transfer time of asking is promptly by adjusting the magnitude of current, with the charging interval of control action phone 1,2 by above-mentioned control unit 14; For example, when charging formality because of urgently finishing rapidly as if the user, can be by the electric power transfer of big electric current, to shorten the charging interval.
Above-mentioned protected location 15 is a thermistor; be its protection battery 11 not reason overcharge and cause battery 11 structural failure; it is by the mode of thermoinduction; utilize to have back reaction when battery 11 overcharges, if reverse voltage excessively rises, this reaction can make battery 11 slight heatings cause battery 11 chemical property to change; and then destruction battery 11 structures; at this moment, promptly by this protected location 15 when battery 11 temperature reach certain upper limit, promptly cut off electric power transfer automatically.
See also shown in Figure 2ly, be the another embodiment of the present invention schematic diagram, as shown in the figure: charging device 4 of the present invention also can be an independent device, and connects two mobile phones 6,7 respectively to carry out electric power transfer by a transmission line 5.
Above-mentioned charging device 4 is made of a control unit 41 and a protected location 42; This control unit 41 is in order to control electric power transfer amount and the electric power transfer time between two mobile phones; 42 of this protected locations because of the input too high voltages, and destroy the inside battery structure in order to the battery (not shown) that prevents two mobile phones 6,7.
In addition, charging device of the present invention except that can be applicable to mobile phone, also can be applicable to personal digital assistant (PERSONAL DIGITAL ASSISTANCE, PDA).
For the understanding in a nearlyer step can be arranged mobile telephone cell charging modes of the present invention, especially exemplified by the lithium battery of a 800mAh capacity as embodiment, the termination charging voltage of this lithium battery is 4.2V, its charging process is carried out constant-current charge earlier, be that battery is with 800mA (charge rate is 1C) constant-current charge, cell voltage boosts with bigger slope during beginning, when cell voltage during near 4.2V, make the constant-voltage charge of 4.2V again into, this moment, electric current gradually fell, and change in voltage is little, when charging current is reduced to 1/10C (about 80mA), think near being full of, promptly can stop charging.
