Abstract
The utility model relates to a self charging device for a mobile phone, and comprises a charging circuit and a rechargeable cell. A winding mechanism type mini motor is arranged inside a casing of the mobile phone. A power supply output terminal of the winding mechanism type mini motor is connected with an input terminal of a rectification and filtering voltage stabilizing circuit. An output terminal of the charging circuit rectification and filtering voltage stabilizing circuit is connected with an input terminal of a power source of the charging circuit. The utility model can be charged by an external charger or by the winding mechanism type mini motor.
Description
The utility model relates to a kind of self charger of mobile phone, particularly a kind of self charger of the mobile phone by Blast Furnace Top Gas Recovery Turbine Unit (TRT) charging.
The battery block that prior mobile phone mostly adopts high-energy, can discharge and recharge continuously provides power supply.Along with the development of technology, the capacity of battery is done bigger and bigger, and the air time can be longer, but a limit is always arranged, and each mobile phone user can run into such problem, and mobile phone is in conversation, because of the dead battery call drop, do not use battery and do not prepare and carry at one's side, have to heave a sigh by the prestige machine.
The purpose of this utility model is to change the traditional mode of only outer charger charging in the past, provide a kind of can the charging of external charge device, the self charger of mobile phone that also can be by the charging of self generating device is to overcome above-mentioned defective.
The self charger of the mobile phone that the utility model proposes, comprise charging circuit and rechargeable battery, be provided with the spiral spring type miniature generator in its mobile phone housing, the power output end of spiral spring type miniature generator is connected with the input of rectification filtering voltage stabilizing circuit, and the output of rectification filtering voltage stabilizing circuit is connected with the power input of charging circuit.
Because the self charger of this mobile phone, be equiped with the spiral spring type miniature generator in its mobile phone housing, when the battery of mobile telephone energy shortage, can charge the battery by the spiral spring type miniature generator, extend working time, when avoiding conversing because of energy content of battery deficiency call drop.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the circuit theory diagrams of the self charger of present embodiment mobile phone.
The playing card charging device of present embodiment mobile phone is that the charging modes to mobile phone is done improvement on the basis of mobile phone.Mobile phone is except that original radio frequency part, baseband portion and man-machine interface part, one spiral spring type miniature generator and rectification filtering voltage stabilizing circuit also is installed in the casing of mobile phone, the power output end of spiral spring type miniature generator is connected with the input of rectification filtering voltage stabilizing circuit, and the output of rectification filtering voltage stabilizing circuit is connected with the power input of the original charging circuit of mobile phone.The charge power supply of mobile phone can be from the charger power supply of outside, also the power supply that can provide from the spiral spring type miniature generator of inside.The spiral spring type miniature generator mainly is made of clockwork spring winding device, drive unit and microgenerator.The clockwork spring winding device can be manual screwing type or automatic screwing type.
When clockwork spring was screwed, because stress, clockwork spring drove the rotor rotation of microgenerator by drive unit, through the conversion of Blast Furnace Top Gas Recovery Turbine Unit (TRT), alternating voltage of microgenerator output is handled through rectification, filtering, voltage stabilizing, to obtain a constant DC and press, supply with charging circuit.
Mobile phone adopts the power supply of 3.6V lithium ion battery, mobile phone adopts charging of external charge device and spiral spring type miniature generator charging dual mode, usually adopt external charge device mode to charge, can adopt the spiral spring type miniature generator charging to continue the air time when emergent.
With reference to Fig. 1, circuit partly is made of power pack and battery charge.
Power pack is provided by two-way, and a route external charger provides, and another route spiral spring type miniature generator provides.When adopting the spiral spring type miniature generator for electricity generation, generator 1 is converted into electric energy to the mechanical energy on the clockwork spring, produces an alternating voltage output, and the direct voltage that produces a 6V after D1-D4 full-bridge rectification, C1 filtering, the D5 voltage stabilizing part that charges the battery is powered.D6, D7 play the diverter switch effect.The battery charge part, wherein LM3420 is the lithium ion cell charging controller, LM317 is the voltage adjustable voltage stabilizer, because the necessary strict protection of the charging voltage of monomer lithium ion battery if surpass 4.5V, will cause permanent damage at 4.1V ± 50MV.
The circuit working principle is as follows: when cell voltage is lower than 3.6V, LM3420 output OUT no-output electric current, transistor Q2 ends, therefore, voltage adjustable voltage stabilizer LM317 output constant current 500MA (this value can be provided with as required) charges the battery, in this process, cell voltage constantly rises, and cell voltage is detected by the input pin IN of LM3420, when voltage is raised to 3.6V, LM3420 output OUT begins output current, makes Q2 begin to control the output voltage of LM317, charger; Change the constant voltage charge process over to, cell voltage be stabilized in 3.6V after this charging current begin to reduce, behind the full charge, charging current drops to trickle-charge current.When too little to the voltage of live part power supply or when interrupting, Q1 ends, LM3420 disconnects.Diode D8 can avoid battery to discharge by LM317.
Generally, can adopt external charge device 2 modes to charge the battery, this is identical with common mobile phone.Under case of emergency, can adopt to screw clockwork spring, charge the battery by inner spiral spring type miniature generator 1 generating.
