Battery electricity-taking device for mobile phone extension device

Abstract

The invention discloses a battery electricity-taking device for a mobile phone extension device. The battery electricity-taking device comprises an electricity-taking piece and an electricity transmission piece which are mutually connected and respectively provided with anode terminals and cathode terminals, wherein, the anode terminal and cathode terminal of the electricity-taking piece are respectively connected with the anode terminal and cathode terminal of the electricity-transmission piece; the anode terminal of the electricity-taking piece is respectively connected with the electricity-taking anode terminal of the mobile phone and the anode terminal of the battery; the cathode terminal of the electricity-taking piece is respectively connected with the electricity-taking cathode terminal of the mobile phone and the cathode terminal of the battery; the anode terminal and cathode terminal of the electricity-transmission piece are connected with the anode terminal and cathode terminal of the mobile phone extension device; the positive-negative poles of the electricity-taking piece are arranged at the connection parts of the electricity-taking positive-negative poles of the mobile phone and the positive-negative poles of the battery, so that the mobile phone can be powered normally by the battery under the condition that the electrical quantity of the battery can be obtained; and besides, the positive-negative poles of the mobile phone extension device and the positive-negative poles of the electricity-transmission piece are connected so as to meet the power supply requirement of the mobile phone extension device.

Description

technical field [0001] The invention relates to the field of smart phones, and more specifically, relates to a battery extractor of a mobile phone extension device. Background technique [0002] With the popularization and enhancement of functions of modern smart phones, people have a strong demand for applications such as electronic payment, product authenticity identification and real-time positioning. [0003] For the expansion of additional functions of smart phones, the current mobile phone suppliers do not give timely updates on the hardware. For example, if you want to realize smart payment, you need the support of RF-SIM card, and you need a module that can identify the radio frequency tag to support it. Since the identification radio frequency module itself needs power supply, however, there is no reserved space in the mobile phone for the identification of the radio frequency module. There is no space for power supply, so the corresponding power cannot be provided...

AI Technical Summary

Problems solved by technology

For example, if you want to realize smart payment, you need the support of RF-SIM card, and you need a module that can identify the radio frequency tag to support it. Since the identification radio frequency module itself needs power supply, however, there is no reserved space in the mobile phone for the identification of the radio frequency module. There is no space for power supply, so it is unable to provide corresponding power for the identification radio frequency module

There are also corresponding problems in the expansion of other smart phone functions, that is, the corresponding power cannot be provided for the expansion module, so that the user's demand for smart phone expansion cannot be met.
