Abstract
The invention provides an overcharge-proof mobile phone, which mainly comprises a chip, a display, keys and a battery, wherein the mobile phone is required to be provided with a matched charger, an overcharge-proof device is arranged in a mobile phone circuit and comprises a detection system, an acousto-optic system and a control circuit, when the mobile phone is in a charging state, the overcharge-proof device is in a short-circuit state, when the detection system monitors that the mobile phone is fully charged, the control circuit of the overcharge-proof device is closed, and the audible and visual system is used for reminding.
Description
Technical field
The present invention relates to a kind of mobile phone, especially a kind of anti over-charging mobile phone.
Background technology
First generation mobile phone (1G) is meant the mobile phone of simulation, just the mobile telephone that occurs in the 80s and 90s in 20th century films and television programs such as Hong Kong U.S..That develop mobile telephone at first is doctor Cooper of U.S. Motorola Inc..Because the antenna that restriction of at that time battery capacity and analog-modulated Technology Need are very large and development of integrated circuits situation or the like restrict, this mobile phone appearance is having the shape of a real square, can only become removablely to be not really portable.A lot of people call this mobile phone and are " brick " or NCC etc.This mobile phone has multiple standard, as NMT, and AMPS, TACS, but use the frequency division multiplexing mode can only carry out voice communication basically, reception effect instability, and confidentiality deficiency, wireless bandwidth utilizes insufficient.Cell phone type is similar to simple radio duplex radio station in this, and conversation is to be locked in certain frequency, so use the Frequency Adjustable radio station just can eavesdrop conversation.Second generation mobile phone (2G) also is modal mobile phone.Usually these mobile phones use PHS, and these very ripe standards of GSM or CDMA have stable speech quality and suitable stand-by time.In order to adapt to the demand of data communication, some intermediate standard are also supported on mobile phone in the second generation, for example support the GPRS of MMS and the WAP service of business of networking, and java applet miscellaneous etc.
The scope that discharges and recharges of battery of mobile phone is safest in 3.6V-4.2V, and 3.0-3.6,4.2-4.5 do not have the danger of blast, but battery life is had certain influence.General electrical appliance control voltage points out electric weight not enough even shutdown automatically in 3.6V.Charger control charger is charged to 4.2V.And 3.0V and 4.5V to be protective circuit the be protection battery just takes place when preventing that electrical appliance and charger are out of control action.So the overprotection circuit also one plays 100% defencive function surely.
Summary of the invention
At the problems referred to above, the invention provides a kind of anti over-charging mobile phone.
A kind of anti over-charging mobile phone, mainly form by chip, display, button and battery, it is characterized in that mobile phone need be equipped with the charger of coupling, be provided with an anti-overcharge device in the mobile phone circuit, comprise detection system, acousto-optic system and control circuit, when mobile phone is in charged state following time, anti-overcharge device is in short-circuit condition, when detection system monitors mobile phone when being full of electricity, the control circuit closure of anti-overcharge device, and remind by acousto-optic system.
Remarkable result of the present invention is that the defencive function of protective circuit is further strengthened; not only can reduce overprotection when incomplete; timely prompting to the people; added anti-overcharge device in the mobile phone; alleviated the circuit pressure of charger; and can reduce the use of overprotection circuit, prolonged the useful life of battery.
Description of drawings
Accompanying drawing is the anti over-charging mobile phone schematic diagram
Wherein: 1, chip; 2, acousto-optic system; 3, detection system; 4, control circuit; 5, charger.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing: mobile phone need be equipped with the charger 5 that is complementary with it, be provided with an anti-overcharge device in chip 1 circuit of mobile phone, comprise detection system 3, acousto-optic system 2 and control circuit 4, when mobile phone is in charged state following time, the control circuit 4 of anti-overcharge device is in short-circuit condition, when detection system 3 monitors battery of mobile phone when being full of electricity, control circuit 4 closures of anti-overcharge device, and remind by the sound and light signal that acousto-optic system sends.
The invention has the beneficial effects as follows the defencive function of holding circuit is further strengthened, not only can reduce Protect when incomplete, the timely prompting to the people has added anti-overcharge device in the mobile phone, has alleviated charger Circuit pressure, and can reduce the use of overprotection circuit, having prolonged the service life of battery, can subtract Few owing to overcharge the battery damage that brings or the danger of exploding, relatively be suitable in the button of electronic product.
