Adjustable positioning wireless charging device

The present invention provides a wireless charging device with adjustable positioning, in particular, a power supply coil that is positioned with a pushing mechanism and a power supply device in the power base, and a power supply device is positioned in the sliding seat of the pushing mechanism, and can be manually changed. Adjusting the position of the power receiving coil of the power supply coil corresponding to the electronic device on the sliding seat to achieve the optimal power charging efficiency.

According to the rapid development of electronic technology and multimedia information, the portable electronic devices such as smart phones, tablet computers, digital cameras and video players have developed toward a light, short, and versatile trend, mainly with small size and light weight. It is easy to carry and other features, plus the soft and hard functions are constantly being introduced, and the use is more practical.

If the electronic device is to be used for personal use, the first thing that must be solved is the problem of power consumption. The general method is to install a rechargeable battery inside the electronic device and match the power of the rechargeable battery with a compatible power supply. It can be recharged when it is exhausted. However, since the specifications of each brand electronic device are very different, it is necessary to use a dedicated power supply to connect through the power cable before charging. If there are multiple electronic devices, the power supply is The power cord is not only troublesome and inconvenient to organize, but also unsuitable for storage or carrying.

In order to solve the above problems, some manufacturers have developed an inductive power supply that can use electromagnetic induction to transmit power, or a wireless charger, which has no contact electromagnetic induction. The power supply mode has excellent convenience. However, the electromagnetic induction power supply mode is simply that the magnetic material of the two coil modules is wound with an induction coil as a power supply end for transmitting power and a power receiving end for receiving power. The mutual induction power can be transmitted through the sensing surface of the coil module. The principle is similar to that of a conventional wound-type power transformer, and an induction coil can be built in different electronic devices to simultaneously support different electronic devices for charging. Solve the inconvenience and troubles that the power supply can't support each other, exchange and use.

However, the coil modules inside the wireless chargers on the market are fixed and cannot adjust the position of the sensing surface, which causes the position of the electronic device to be limited. When the coil module of the receiving end of the electronic device receives power, It must be placed in accordance with the position of the coil module on the power supply end of the wireless charger to achieve the best power charging efficiency. However, the specifications of each brand electronic device are different, so that the position of the coil module is not The same, the electronic device not only needs to pay extra attention to the charging position when placed, but also must be used with different wireless chargers, so that it is quite inconvenient to use and cannot be shared with other electronic devices. For the manufacturer Therefore, it is necessary to develop a wireless charger with a plurality of different coil module positions at the same time, which causes a substantial increase in production cost and does not meet the consideration of economic efficiency, that is, the direction for those who are engaged in this industry to research and improve.

Therefore, in view of the above-mentioned problems and deficiencies, the new creators have collected and reviewed relevant materials through multi-party evaluation and consideration, and have continuously tried and modified the years of research and development experience in this industry to design such an adjustable positioning wireless charging device. A new type is born.

The main purpose of the creation is that the housing space inside the power base is positioned with a pushing mechanism and a power supply device, and a sliding space is formed inside the base of the power base. The shifting mechanism has a sliding seat located in the sliding space of the base, and the power supply coil of the power supply device is positioned in the positioning space inside the sliding seat. When the user adjusts, only the manual shifting is performed on the sliding seat. The power supply coil is slidably displaced along the sliding space of the base to facilitate adjusting the position of the power receiving coil of the power feeding coil corresponding to the sensing surface of the electronic device placed on the base, and the electronic device with different positions of different power receiving coils The same power base can be shared for wireless inductive charging, thereby achieving optimal power charging efficiency, and has the advantages of simple operation, accurate positioning, and wide applicability and applicability.

The secondary purpose of the present invention is that a rail portion is formed above the base of the power base, and a rail portion is provided at the side wall surface of the sliding space formed inside the extension plate body, and the sliding seat of the pushing mechanism is provided. The two sides are provided with a sliding portion located at the rail portion, and the sliding portion is provided with a pulling portion exposed at the power base, which can be utilized when the user moves over the pulling portion of the sliding seat. The elastic buckle on the sliding portion is an adjustment action for holding the positioning by the retaining groove of the engaging portion of the rail portion at a predetermined interval, and a certain paragraph feel is generated when the sliding seat is adjusted, so as to know that the adjustment has been completed. The guiding and limiting action of the rail portion of the base can also make the sliding displacement of the sliding seat as a whole smoother and smoother.
