Problems solved by technology

[0003] There is a common shortcoming in the mobile phone batteries commonly used in the existing market: when the battery power is low, once there is an incoming or outgoing call, the mobile phone may automatically shut down during the answering or talking.
[0006] 2. Too many switches will have a great impact on the life of the mobile phone
[0007] 3. Sometimes the call must be terminated because of changing the battery, which is very inconvenient
[0008] 4. The mobile phone is shut down due to no electricity, so there is no buffer time
[0009] 5. Large radiation when switching on and off
The device does not have the function of automatically switching batteries, it must be switched manually, and there is a certain time delay when the sliding control switch 6 slides, which will cause the shutdown of the mobile phone and affect the ongoing work of the mobile phone

Embodiment 1

[0040] A mobile phone with uninterrupted power supply of the present invention includes a mobile phone body with a mobile phone input bus, a mobile phone working bus, a mobile phone redundant bus and a main power supply, and also includes: an auxiliary power supply, the input terminals of the main power supply and the auxiliary power supply Both are connected to the input bus of the mobile phone, and the output ends are connected to the working bus of the mobile phone; and one is respectively connected to the main power supply and the auxiliary power supply, measures the voltage value of the main power supply and the auxiliary power supply, and controls the conduction of the main power supply and the auxiliary power supply Status of the power management control module.

[0041] Among them, the main function of the mobile phone input bus is to transmit the data information input by the user, and also to transmit the command and data information from the mobile phone control chip...

Embodiment 2

[0053] Since in embodiment 1, operations such as measuring voltage and sending instructions are all completed by a power management control module, its structure is bound to be very complicated, and the cost of using a single chip or module to complete these functions is high, and its stability and replaceability are poor.

[0054] Such as Figure 4 As shown, the power management control module is divided into the first switch S1 corresponding to the main power supply and the first control module for measuring the voltage of the main power supply, controlling the conduction state of the first switch S1, and the second switch S2 corresponding to the auxiliary power supply and measuring the auxiliary power supply. A power supply voltage, a second control module for controlling the conduction state of the second switch S2, and a master control module.

[0055] Wherein, the main and auxiliary power supplies each include a SENSE+ terminal;

[0056] The first switch S1 is connected...

Abstract

The invention discloses a mobile phone capable of supplying uninterruptible power and a method for automatically switching over power supplies. The mobile phone comprises a mobile phone body with a mobile phone input bus, a mobile phone work bus, a mobile phone redundancy bus and a main power supply, an auxiliary power supply and a power supply management control module. The input ends of the main power supply and the auxiliary power supply are connected with the mobile phone input bus, and the output ends of the main power supply and the auxiliary power supply are connected with the mobile phone work bus. The power supply management control module is respectively connected with the main power supply and the auxiliary power supply, measures voltage values of the main power supply and the auxiliary power supply and controls connection states of the main power supply and the auxiliary power supply. The difficulty in the prior art is overcome, and the purpose of automatically switching over the power supplies in a mobile phone using state is achieved.

Description

technical field [0001] The invention relates to an uninterrupted power supply system, in particular to a mobile phone with uninterrupted power supply and a method for automatically switching the power supply thereof. Background technique [0002] At present, mobile phones have more and more functions, such as: large-screen high-resolution display, photography with flash light, music or video playback, etc., resulting in a battery that usually does not last long. Generally, the video is played continuously, and the battery of an ordinary mobile phone can only be used for about 6 hours, and the battery has become very frequent. [0003] There is a common shortcoming in the mobile phone batteries generally used in the existing market: when the battery power is low, once there is a call incoming or outgoing, the mobile phone may automatically shut down during answering or talking. Even if it is found that the battery of the mobile phone is low in time, if it is charged at this ...
