Problems solved by technology

[0006] However, the above-mentioned isolation arrangement will result in the inability to dissipate heat by gas convection between the inside of the casing 10 and the outside, so that the heat generated by the circuit board 12 and the induction transmission coil 13 will continue to accumulate inside the casing 10 and is difficult to escape outwards. scattered
Therefore, after the existing wireless charging device 1 is used for a period of time, the temperature will continue to rise and cannot be lowered, and eventually it may be damaged due to excessive temperature. This is a potential danger that cannot be ignored in terms of safety in use.

Abstract

The invention provides a wireless charging device which comprises a circuit board, a heat absorbing plate, an induction transfer coil and a casing body. The induction transfer coil is arranged on the heat absorbing plate. The heat absorbing plate is arranged on the circuit board. The casing body covers the circuit board, the heat absorbing plate and the induction transfer coil. The heat absorbing plate has at least one hole, so that the entropy of the heat absorbing plate is increased, and the heat absorbing ability of the heat absorbing plate is improved. According to the invention, the whole wireless charging device is prevented from overheating, and the use safety of the wireless charging device is improved.

Description

technical field [0001] The invention relates to a wireless charging device, in particular to a wireless charging device with a heat absorbing plate. Background technique [0002] Generally speaking, if the electronic device is equipped with a rechargeable battery, when the power of the rechargeable battery in the electronic device is insufficient, the user can use a charging device to charge the rechargeable battery. The existing charging device has a transformer and a connection line. The user plugs the transformer into the power supply and inserts the connection line into the electronic device, so that the existing charging device can transmit current to the electronic device through the connection line. . However, before charging the existing charging device, the user must use both hands to hold the electronic device and the connecting wire separately to perform the action of plugging the connecting wire into the electronic device; Grasping the electronic device and the...
