Problems solved by technology

For example, in recent years, in order to make up for the battery capacity problem caused by the bottleneck of battery technology, major mobile phone manufacturers have adopted the method of increasing the charging power to make up for this defect. The speed will be greatly improved, but blindly increasing the charging power will definitely cause serious heat dissipation problems. The higher the heat, the more obvious the user will feel hot, which seriously affects the user experience

Embodiment 1

[0020] figure 1 It is a block diagram of the first embodiment of the back clip of the present invention. This embodiment proposes a back clip, which includes: a Hall sensor module 10, a Bluetooth chip module 20, a light control module 30, a fan control module 40, a cooling chip control module 50, and a power management module 60, wherein the The Hall sensor module 1010 is used to detect whether the back clip and a device are in an assembled state, and the Bluetooth chip module 20 is used to receive input from the Hall sensor module 10 when in the assembled state. low level, and establish a Bluetooth connection with the device, the lighting control module 30 is used to receive the first control data of the Bluetooth chip module 20, and adjust the working state of the light group according to the first control data, The fan control module 40 is used to receive the second control data of the Bluetooth chip module 20, and adjust the working state of the fan according to the secon...

Embodiment 2

[0027] Based on the above-mentioned embodiment, the power management module 60 is used to activate the Hall sensor module 10 when the back clip establishes a power connection with the device, so as to detect whether there is a power connection between the back clip and the device. The state of assembly.

[0028] Optionally, in this embodiment, in order to determine in time whether the cooling back clip is installed on the mobile phone by the user, this embodiment uses the Hall sensor module 10 for implementation.

[0029] Optionally, in this embodiment, in order to better adapt to different mobile phones, the stretchable area is designed. When the user installs the back clip to the mobile phone, it must be stretched and then installed on the mobile phone. Therefore, the magnet is installed on the Stretch area.

[0030] Optionally, in this embodiment, when the user is not using the magnet, the Hall sensor will detect the magnet, and when the user is using it, the magnet will s...

Embodiment 3

[0033] Based on the above-mentioned embodiment, the detection end of the Hall sensor module 10 is set in the stretching area of ​​the back clip, and when the stretched range of the back clip exceeds the detection range of the detection end, it is determined that the back clip in the assembled state.

[0034] Optionally, in this embodiment, the chip of Hall sensor module 10 adopts AH1898 of Diodes, and VDD adopts 3V power supply, thus, this embodiment can select one of the two magnetic sensitivity bands through the BSEL pin without Adding any external components allows for a flexible and small solution.

[0035] Optionally, in this embodiment, when the magnet gets closer to the upper magnetic field, it outputs a high level, indicating that the user has not loaded the back clip on the mobile phone; when the user pulls the back clip magnet away, the output of the interrupt INT pin is low , indicating that the user has loaded the back clip on the mobile phone, and can drive other...

Abstract

The invention discloses a back clamp, which comprises a Hall sensor module, a Bluetooth chip module, a light control module, a fan control module, a refrigeration sheet control module and a power management module. The Hall sensor module is used for detecting whether the back clamp and equipment are in an assembly state or not. The Bluetooth chip module is used for receiving a low level input by the Hall sensor module and establishing Bluetooth connection with the equipment when the back clamp and the equipment are in an assembly state, so that a faster cooling effect and a better light visual effect can be obtained when the back clamp is assembled to the equipment. The control logic of the back clamp is optimized, the autonomous controllable performance of the back clamp is improved, and the user experience is enhanced.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a back clip. Background technique [0002] In the prior art, with the continuous development of smart terminal devices, users have higher and higher heat dissipation requirements for smart terminal devices such as mobile phones. For example, in recent years, in order to make up for the battery capacity problem caused by the bottleneck of battery technology, major mobile phone manufacturers have adopted the method of increasing the charging power to make up for this defect. The speed will be greatly improved, but blindly increasing the charging power will definitely cause serious heat dissipation problems. The higher the heat, the more obviously the user will feel hot, which seriously affects the user experience. Contents of the invention [0003] In order to solve the above-mentioned technical defects in the prior art, the present invention proposes a back clip, which inclu...
