Problems solved by technology

Mobile phone batteries are usually lithium polymer batteries with a certain unit power density. The larger the battery capacity, the larger the volume and the heavier the weight. The larger the battery capacity, the thinner and thinner the mobile phone cannot be; due to the characteristics of lithium batteries, the charging voltage is usually fixed at 5 Using a large charging current can shorten the charging time, so that users can obtain enough power in a short charging time. The disadvantage is that a matching high-current charger is required, and ordinary users will not carry the charger with them.

Embodiment 1

[0034] An airflow charging device applied to a mobile phone, comprising an airflow expander 10, a power generating mechanism 20, and an electric energy collector 30; the airflow expander 10 includes an inlet 11 and an outlet 13, which are arranged inside the mobile phone, and the external airflow flows from the airflow expander 10 After the inlet 11 of the airflow expander enters, it becomes a strong airflow and flows out from the outlet 13 of the airflow expander 10; Electric energy; the electric energy collector 30 is electrically connected with the power generating mechanism 20, and collects and stores the electric energy generated by the power generating mechanism 20. Optionally, the air expander 10 further includes an elastic plectrum 12 , the elastic plectrum 12 is arranged at the inlet 11 of the air expander 10 to open or close the inlet 11 of the air expander 10 .

[0035] In this embodiment, the airflow charging device includes an airflow expander 10 , a power generat...

Embodiment 2

[0038] Embodiment 2 is yet another embodiment based on Embodiment 1, such as figure 2 As shown, in addition to the structure of the embodiment, the power generating mechanism 20 includes a diaphragm, a coil, and a magnet; the diaphragm is deformed under the action of a force, and the deformation recovers after losing the action of the force; the magnet is arranged behind the diaphragm and formed behind the diaphragm. Magnetic field: the coil is fixed behind the diaphragm and surrounded by the magnetic field, the coil moves linearly under the drive of the diaphragm, and the direction of the coil movement is perpendicular to the direction of the magnetic field of the magnetic field. Preferably, the power generating mechanism 20 is a speaker 21 . Optionally, the power generating mechanism 20 further includes a switch 22, which is electrically connected to the speaker 21, and the switch 22 enables the speaker 21 to be in different working modes, including a sounding mode and a ge...

Embodiment 3

[0045] Embodiment three is another embodiment based on the improvement of embodiment two, such as figure 2 As shown, an optional rectifier 40 and an optional voltage regulator 50 are also included. The rectifier 40 is electrically connected to the power collector 30 and converts the power stored in the power collector 30 into direct current. The voltage regulator 50 is electrically connected with the rectifier 40 and the battery of the mobile phone, and transmits the direct current to the battery of the mobile phone at a specific voltage.

[0046] In this embodiment, it involves the peripheral circuit connected with the power generating mechanism 20, mainly including a rectifier 40 and a voltage regulator 50, which are used for voltage regulation and rectification, so that the electric energy from the electric energy collector 30 forms a characteristic voltage direct current to power the mobile phone battery. Charge. As mentioned above, the power generating mechanism 20 has ...

Abstract

The invention discloses an airflow charging apparatus applied to a mobile phone. The airflow charging apparatus comprises an airflow expander, a power generation mechanism and an electric energy collector, wherein the airflow expander comprises an inlet and an outlet, and is arranged in the mobile phone; external airflow enters the inlet of the airflow expander and becomes powerful airflow, and the powerful airflow flows out of the outlet of the airflow expander; the power generation mechanism is arranged at the outlet of the airflow expander, and generates electric energy under the action of airflow pressure at the outlet of the airflow expander; and the electric energy collector is electrical connected with the power generation mechanism, and collects and stores the electric energy generated by the power generation mechanism. According to the airflow charging apparatus built in the mobile phone, provided by the invention, power is generated by kinetic energy of the airflow of the external environment, so that the power utilization demands of existing mobile phones are met and a function of charging at any time is realized on the premise that the mobile phones do not need to be transformed remarkably.

Description

technical field [0001] The invention relates to the field of mobile phone charging, in particular to an airflow charging device applied to mobile phones. Background technique [0002] At present, mobile phones are becoming the focus of technological development. No matter the processor, memory, or screen display technology is developing rapidly, the performance of mobile phone processors is getting stronger and stronger, the memory is getting bigger and bigger, and the screen display effect is getting better and better. The only The battery technology is developing slowly. For mobile terminals including mobile phones, the battery is becoming the technical bottleneck of the entire device. As a mobile communication tool, mobile phones have more and more functions with the development of technology, such as Watching videos, listening to music, navigating, etc., but the most basic function is communication. If the mobile phone cannot keep working for a long time, no matter how p...
