Cell phone shell with RF (Radio Frequency) remote control function

Abstract

The invention discloses a cell phone shell with an RF (Radio Frequency) remote control function. The cell phone shell is internally provided with an RF transmitting and receiving module and a physical keyboard combination, which are connected with a cell phone digital charging interface; the cell phone digital charging interface can be combined with a processing capability of the cell phone to receive and learn an RF signal; the RF signal of one or more frequency bands is transmitted when a press key is pressed each time, so that RF remote control equipment is controlled; a key slot is formed on a side face of a cell phone shell body and an entity key can be inserted into the key slot; when power is off, the corresponding equipment can be unlocked through the entity key so that objects needing to be carried by people are reduced; meanwhile, the cell phone shell can be further provided with various practical modules including a wireless positioning module, an earphone audio interface and the like which are connected with the cell phone through the cell phone digital charging interface, so that functions of a cell phone are expanded and updated and people do not need to frequently change the cell phone.

Description

[0001] Technical field: [0002] The invention relates to a mobile phone case with RF radio frequency remote control function. [0003] Background technique: [0004] With the development of science and technology, many electrical appliances and equipment have added wireless remote control function. Among them, RF radio frequency remote control function is widely used as the remote control of equipment due to its low power consumption, two-way communication and good signal penetration characteristics. Different devices will have different RF remote controllers. If there are many wireless RF control devices around, you need to carry multiple RF remote controllers, which is not convenient. With the popularity of smart phones, smart phones have become one of the essential devices in people's daily life, but few smart phones integrate RF radio frequency modules, so that the radio frequency remote control still needs to be carried separately, which largely limits Further developmen...
