Description

Wireless charging clip structure

The present invention relates to a technical field for improving an existing wireless charging device, which is an electromagnetic energy transfer (Electromagnetic Power Transfer), which uses a magnetic structure of a "clamp-type structure" and a charging coil to wirelessly transmit electric energy to electromagnetic induction. The rechargeable device converts the electromagnetic energy into various forms of smart charging DC power through the coupled electromagnetic coil and the related charging circuit or the control IC on the device, performs wireless charging of the battery on the device, and improves the traditional wireless charging technology. The use of ergonomic hand (hand bow) maximizes the fit of the human body's familiar areas and natural forms of technology when using tools, effectively increasing the convenience of the use of this creation.

In the field of wireless charging of rechargeable devices, there have been known inductive charging devices for electric toothbrushes. Since electromagnetic induction is a commonly known technique, its configuration must be coupled to or close to the electromagnetic coil. The electrical energy can be transmitted to the charged device through the induced magnetic field coupling. Even with the latest wearable mobile devices, there is a technical field in which this method is used for charging.

The conventional wireless charging technology can be roughly divided into three types according to the electromagnetic operation mode: first, electromagnetic induction, magnetic resonance, and capacitive coupling. If the mode of operation is roughly divided into two One is linear power converters and the other is switching power converters. The frequency range of electromagnetic application is wider, the magnetic induction can be from tens of Hz to several MHz, the magnetic resonance can be from several KHz to several GHz, the capacitive coupling can be from several KHz to several GHz, and the microwave transmission is up to several GHz. Therefore, although it is also an inductive charging device, there are many different embodiments of the technical features of its application.

Another type of wireless charging technology is through various types of radio waves, through high-frequency waves, microwaves, light waves, lasers, etc. in a short range, without touching or approaching the device being charged, the electric energy can be transmitted through the wireless The electric wave is transmitted to the charged device. However, the efficiency of charging is also lower than that of the inductive type. However, some manufacturers have already introduced commercial products, which can charge multiple devices at the same time, and various types of radio waves may have doubts about whether they affect human health. The electromagnetic wave energy absorption ratio SAR (Specific Absorption Rate) of CNS14959 is specified at 2.0W/Kg, and whether it will interfere with other electronic or communication devices remains to be seen.

Currently, there are about three major charging standards organizations in the wireless charging market, including Wireless Charging Consortium (WPC), Alliance for Wireless Power (A4WP) and Power Matters Alliance (PMA). The wireless charging technology features promoted by various organizations are different, and are constantly being updated. Whether there is a newer, more efficient, and more distant wireless charging product technology in the future is still waiting for the R&D investment of the technology industry.

Recently, South Korea's Samsung (Samsung) in the flagship Galaxy S6 and S6 Edge smart phones, while using Powermat (Power Matters Alliance PMA) and Qi (Wireless Power Consortium WPC) two wireless charging standards. The Qi standard currently supports inductive or tightly coupled, wireless charging at specific points. It is reported that Qi also publishes an extension technology that can be wirelessly charged in a resonant manner over a few miles.

As early as 2005, Apple introduced the Zero-contact induction wireless charging technology, which can not only charge but also transmit data. In 2012, Apple received the US patent for "Near Field Magnetic Resonance (NFMR). The patented technology report indicated that it can charge peripheral devices within one meter. The power is projected by a computer such as an iMac. For example, a wireless mouse delivers charging power.

Regardless of whether it is a near-contact inductive charging device or a close-range radio wave charging device, the prior art has been inspected, and no product having a structural feature of the "clip structure" has been constructed. The prior art has focused on the technical characteristics of the charging control circuit, the charging induction coil structure, the near field communication, the wireless transmitting and receiving function, the charging base structure, the microwave DC antenna, the device authentication, the resonance design, and the transmission information, etc. The "clip structure" has different structural features.

As rechargeable devices become smaller and smaller, such as earbuds, Bluetooth headsets, keychain lights, MP3 music players, traditional micro USB connectors, replacement button batteries, or traditional wireless charging configurations are no longer sufficient. Needs. Moreover, there are more and more rechargeable devices, which have been designed to be completely sealed and waterproof, such as remote control, computer, key remote control, Bluetooth glasses, watches, thermometers, Bluetooth anti-lost devices, etc., and more need no complete electrical metal connection. Wireless charging design for holes, or even waterproof forms.

Therefore, the creator feels that there is still room for improvement in the above-mentioned defects, and proposes a structural design that can effectively and rationally improve the traditional wireless charging. This creation uses ergonomic principles to maximize the fit of the human body with the familiar field and natural form.

Therefore, it is impossible to provide the user with an ergonomic and easy-to-operate wireless charging device. The main purpose of this creation is to provide a "mechanical clip-on structure" for quickly "clamping" the rechargeable device, which can instantly clamp the wireless charging device that is aligned with the electromagnetic coil coupling portion, and is familiar with the ergonomic hand tool.

Wireless charging design. The main purpose of this creation is to provide a wireless charging device capable of wirelessly charging a sealed waterproof rechargeable device. The creation itself can also be designed as a waterproof type of implementation, using waterproof design as a technical means to effectively overcome the waterproof device wirelessly. Technical issues of charging.

Another technical problem to be solved by this creation is to improve the traditional micro USB (Micro USB) connector, mini USB (Mini USB) connector, 3.5mm four-conductor TRRS phone connector, 3.5mm three conductor (TRS), 3.5mm two-conductor (TS), 2.5mm two-conductor (TS) and 2mm two-conductor (M4), 3.5mm two-conductor (G5) and Apple's Lightning and other connectors, all require metal conductive joints, so dust, hair The pollution of velvet, hand stains, oxides, corrosion, oil stains, etc., will cause poor contact of the metal conductive joints, resulting in a general failure of charging. The main purpose of the present invention is to provide a wireless charging device with no metal-free conductive joints, so that the rechargeable device can effectively perform wireless charging.

At the same time, it can also be equipped with a fulcrum or no-point mechanical clamp structure to complete the implementation of different device clip-type construction.
