Description

Car mobile phone magnetic adsorption charging device

technical field

The utility model belongs to the technical field of electronic products, in particular to a magnetic adsorption charging device for a vehicle-mounted mobile phone.

Background technique

Most of the current car mobile phone holders do not provide power supply. If the mobile phone is used in navigation mode for a long time while driving, it will soon lead to insufficient power of the mobile phone.

Some manufacturers have different solutions for this situation. The simplest one is to attach a charging power cord under the bracket. After fixing the mobile phone on the bracket, plug the charging cable into the mobile phone. This method is reliable for charging, but it is slightly inconvenient during use.

Another solution is to use the current cutting-edge wireless charging technology, wireless charging technology (Wireless charging technology; Wireless charge technology). Wireless charging technology originates from wireless power transmission technology. Wireless charging, also known as inductive charging, non-contact inductive charging, uses near-field induction, that is, inductive coupling, to transmit energy from a power supply device (charger) to a device that uses electricity, and the device uses the received energy to The battery is charged and simultaneously used for its own operation.

Wireless charging technology has the following advantages:

1. Safety: The non-energized contact design can avoid the danger of electric shock.

2. Durability: The power transmission components are not exposed, so they will not be corroded by moisture and oxygen in the air; there are no contacts, so there will be no loss caused by mechanical wear and flashover during connection and separation .

Making Medical Implants Safer: On Implantable Embedded Medical Devices, it is possible to charge medical devices implanted in the human body without damaging body tissues without the need for wires to pass through the skin and other autologous tissues , to avoid the risk of infection.

3. Convenience: There is no need to connect with wires when charging, just put it near the charger. Technically, one charger can power multiple electrical devices. In the case of multiple electrical devices, it can save multiple chargers, occupy multiple power sockets, and avoid the trouble of multiple wires being entangled with each other. .

Of course, wireless charging technology also has the following disadvantages:

1. Low efficiency: the efficiency of energy storage and transmission is not as good as that of real contact.

2. Slow charging speed: Due to low efficiency, the charging speed is slower under the same input power.

3. High cost: The charger needs to have an electronic circuit to drive the wireless coil, and the electric device needs to have an electronic device for power exchange. Both of them also need to have a wireless coil, so the cost is higher than that of direct contact.

Cannot charge while moving: This problem only occurs on mobile devices. For example, the electric shaver cannot be removed from the charger while it is charging. On the contrary, the traditional wire-connected design can continue to be used when the wire is connected to the charger.

4. Low compatibility: Wireless charging devices of different brands cannot be interchanged because there is no unified standard. At present, there are three major alliances in the industry, PMA, WPC, and A4WP, each of which implements different standards. The QI standard implemented by WPC, which has the largest number of members, has already been followed by many products around the world, hoping to achieve a unified standard.

Wireless charging technology uses inductive coupling to transmit energy between the charger and the power-consuming device, and there is no need for wires to connect the two. Therefore, both the charger and the power-consuming device can have no exposed conductive contacts. Use magnetic adsorption or vacuum suction cup to absorb the mobile phone to the wireless power supply distance, and charge the mobile phone through the built-in or external receiving coil of the mobile phone. This solution is convenient to use, but the charging efficiency of the wireless charging method is low, and the power loss is serious. In order to balance the convenience of use and charging efficiency, it is necessary to redesign the charging system by combining the advantages of the two charging modes.
