Technical Field
[0001] The patent of this invention relates to the field of energy storage and heat dissipation technology, and in particular to an energy storage and heat dissipation mobile phone case based on wireless reverse charging technology. Background Technology
[0002] With the rapid development of smart phones, their functions and performance have been significantly improved, and even dual-core and multi-core mobile phones have appeared. At the same time, it has become a common phenomenon for smart phones to overheat. In particular, when gamers use smart phones to play electronic games, the heat generated will surge, and the temperature can even reach above 45°C. The continuous high temperature of mobile phone devices will trigger the chip to reduce the frequency, causing the performance of the mobile phone to decline, resulting in jams when using it, and in severe cases, the battery in the mobile phone device will malfunction. This series of problems seriously affects the user experience and also brings certain safety hazards to people's lives.
[0003] In order to solve the problem of overheating of mobile phones during use, which leads to the inability to run for a long time with high performance, users usually configure heat dissipation back clips for electronic devices. The heat generated by the mobile phone can be dissipated by the micro fan installed in the heat dissipation back clips during use. The mainstream heat dissipation back clips on the market currently use an external charging mode. If you forget to charge in advance and cannot connect to a power source during use, the problem of mobile phone heat dissipation cannot be solved in time, especially when the mobile phone is in an emergency overheating situation, the need for timely heat dissipation is urgent. SUMMARY OF THE INVENTION
[0004] In view of this, the present invention patent proposes an energy storage and heat dissipation mobile phone case based on wireless reverse charging technology, which is equipped with a wireless reverse charging device. When the temperature of the mobile phone is reduced to a certain temperature, the electric energy of the mobile phone is stored in the battery. When the temperature of the mobile phone exceeds a certain temperature, the thermal switch is closed, and the semiconductor cooling sheet starts to work to dissipate the heat of the mobile phone in time.
[0005] The technical means adopted by the present invention are as follows: an energy storage and heat dissipation mobile phone case based on wireless reverse charging technology, comprising a mobile phone protective case body and an energy storage and heat dissipation device body, wherein the mobile phone protective case body is provided with an installation cavity for placing the mobile phone, and a cavity is formed between the mobile phone protective case body and the energy storage and heat dissipation device body; a reverse charging system is embedded in the back of the inner plate of the mobile phone protective case body, and two leads of the reverse charging system circuit are connected to the battery in the attached cavity, and the battery is connected to the semiconductor cooling sheet, and the battery is charged by the reverse charging system to realize reverse wireless charging and energy storage; the semiconductor cooling sheet is discharged by the battery to realize the heat dissipation of the mobile phone.
[0006] Further, the wireless reverse charging system includes a wireless reverse charging disc coil, a transmitter, a receiver, a voltage regulator, and multiple diodes and multiple capacitors connected to the disc coil. The transmitter generates a changing magnetic field through the current of the mobile phone, while the receiver converts this magnetic field back into electrical energy through induction and supplies it to the storage battery.
[0007] Further, the thermal switch is set to close at 35°C.
[0008] Further, the voltage of the storage battery is 4.2V.
[0009] Further, the inner height of the cavity is 3 - 5 mm.
[0010] Further, a micro LED display module for displaying the power contained in the storage battery is provided on the left end face of the main body of the energy storage and heat dissipation device. The micro LED display module is connected in parallel to the circuit of the storage battery and the semiconductor refrigeration sheet and is connected in series with a resistor.
[0011] The present invention has the following advantages:
[0012] 1. By installing an energy storage and heat dissipation device on the back of the traditional mobile phone case, the wireless reverse charging system embedded in the inner back plate of the mobile phone case charges the storage battery installed on the energy storage and heat dissipation device through the electrical energy generated by the mobile phone reverse charging, thus realizing reverse wireless charging energy storage. Then, the heat of the mobile phone is dissipated in a timely manner through the semiconductor refrigeration sheet powered by the storage battery. Its overall structure is simple, and the thickness is only about 1 / 4 of the thickness of the traditional mobile phone back clip. It can dissipate heat from the mobile phone without an external power supply, which is extremely convenient.
[0013] 2. A thermal switch is connected in the connection circuit between the storage battery and the semiconductor refrigeration sheet. When the temperature of the mobile phone exceeds 35°C, it can be turned on, which can effectively prevent the mobile phone from getting stuck due to overheating and ensure a good user experience when using the mobile phone.
[0014] 3. A micro LED display module for displaying the power contained in the storage battery is provided on the left end face of the main body of the energy storage and heat dissipation device, enabling users to timely understand the power of the storage battery, which is very user-friendly.
