Intelligent card for mobile phone getting electricity by lithium battery of the mobile phone

Abstract

The invention discloses an intelligent card of a mobile phone, which comprises an intelligent card main body with a plurality of pins, a connection plate and an electricity taking plate, wherein the standby pin of the intelligent card main body is connected with the anode end of the electricity taking plate through the connection plate, the zero potential end of the intelligent card main body is connected with the cathode end of the electricity taking plate, the anode end of the electricity taking plate is respectively connected with the electricity anode end of the mobile phone and the anode end of a battery of the mobile phone, the cathode end of the electricity taking plate is respectively connected with the electricity taking cathode end of the mobile phone and the cathode end of the battery of the mobile phone, the standby pin of the intelligent card main body is connected with the anode end of an expansion device of the mobile phone, the zero potential end of the intelligent card main body can be connected with the cathode end of the expansion device of the mobile phone, the anode and the cathode of the electricity taking plate can be arranged at the connection positions of the electricity taking anode and the electricity taking cathode of the mobile phone and the anode and the cathode of the battery, the normal electricity supply of the battery for the mobile phone is not influenced, in addition, the anode and the cathode of the expansion device of the mobile phone are connected with the standby pin and the zero potential end of the intelligent card main body, so that the electricity supply requirements of the expansion device of the mobile phone can be met.

Description

technical field [0001] The invention relates to the field of smart phones, more specifically, to smart cards for mobile phones. 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 for the identification radio frequen...

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 with other expansions of smartphone functions, that is, the corresponding power cannot be provided for the expansion module, so that the user's demand for smartphone expansion cannot be met.
