Technical Field

[0001] This utility model belongs to the field of wireless charging technology, specifically relating to a transmitting device, a receiving device, and a wireless charging system. Background Technology

[0002] Traditional wired charging methods typically have the following problems:

[0003] 1. Charging cables are required. In some situations, charging cables may be worn, tangled, short-circuited, or damaged, which may lead to safety hazards.

[0004] 2. Users may forget to bring their charging cable, causing inconvenience.

[0005] 3. In some spaces with limited space, the presence of charging cables may take up space and affect the cleanliness and aesthetics of the environment.

[0006] 4. Traditional wired charging methods may encounter problems such as poor contact during the charging process, which affects charging efficiency.

[0007] 5. In traditional wired charging, the resistance of the charging cable leads to a certain amount of energy loss.

[0008] 6. Traditional charging methods require accessories such as charging cables and chargers, which not only increase costs but are also prone to damage or loss.

[0009] Therefore, wireless charging technology was developed, which can avoid most of the problems of the wired charging method.

[0010] The heat dissipation of the transmitting device in existing wireless charging devices is a crucial research area in wireless charging technology. Wireless charging technology uses electromagnetic induction to transfer electrical energy from the transmitting coil to the receiving coil. During this process, electromagnetic losses in the coil cause power dissipation, generating heat. As wireless charging power increases, the heat generated by the transmitting device also increases accordingly, making the heat dissipation problem more prominent. The heat dissipation problem of the transmitting device has the following serious consequences: 1. Reduced charging efficiency: High temperatures affect the operational stability of electronic components, leading to a decrease in charging efficiency; 2. Shortened device lifespan: Excessively high operating temperatures accelerate the aging of electronic components, shortening their lifespan.

[0011] Existing wireless charging devices typically place the receiver at the user's end to charge the user's battery. However, these receivers are relatively large, presenting the following problems: 1. High cost: The large size leads to higher raw material consumption, increasing manufacturing costs; 2. Limited portability: The large size makes it difficult to integrate the receiver into miniaturized products; 3. Limited application scenarios: In space-constrained scenarios, the large size limits the receiver's application, causing inconvenience to consumers. Utility Model Content

[0120] In use, the transmitter cable 11, extending from the other end of the transmitter housing, is connected to an external power source, typically AC or DC power converted to a preset voltage and current. The receiver cable 21, extending from the receiver housing, is connected to the user's energy storage battery. After the transmitter 1 is powered on, the transmitter coil of the wireless charging transmitter operates, generating a rapidly changing magnetic field. When the wireless charging receiver with a receiving coil approaches the wireless charging transmitter, preferably when the lower connecting plate 23 of the receiver 2 approaches the upper base plate 12 of the transmitter 1, the receiving coil is placed in the changing magnetic field generated by the transmitter coil. According to the principle of electromagnetic induction, the changing magnetic field induces an electromotive force in the receiving coil. The induced electromotive force forms an induced current in the receiving coil.
