[0026] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] With the rapid development of consumer electronics, smart rings, as an emerging type of smart wearable device, are constantly enriching their functions. However, due to their small size and limited battery capacity, charging issues have always been a key factor restricting their development and user experience. Existing charging methods often require connecting cables or specific charging docks, which are not very convenient.
[0028] To address the problems existing in the prior art, this utility model provides a wireless charging device for smart rings. Figure 1 A perspective view of a smart ring provided in an embodiment of this utility model; Figure 2 A side view of a smart ring provided according to an embodiment of the present invention; Figure 3 This is a schematic diagram of the structure of a charging transmitter provided in one embodiment of the present invention. Figure 1-3As shown, the wireless charging device for a smart ring includes a smart ring and a charging transmitter 500. The smart ring includes a battery motherboard 300 and a receiving coil 400. The receiving coil 400 is disposed on the surface of the battery motherboard 300 and is communicatively connected to the battery motherboard 300. The charging transmitter 500 is communicatively connected to the receiving coil 400. The charging transmitter 500 emits electromagnetic energy to the receiving coil 400. The receiving coil 400 receives the electromagnetic energy emitted by the charging transmitter 500 and converts it into electrical energy to wirelessly charge the smart ring. By adding a receiving coil 400 to the smart ring, which receives the electromagnetic energy emitted by the charging transmitter 500 and converts it into electrical energy, short-range wireless charging of the smart ring is achieved, freeing users from the constraints of cables and making charging more convenient. At the same time, this charging method also reduces the risk of device damage caused by frequent plugging and unplugging of the charging interface, improving the overall reliability and lifespan of the smart ring.
[0029] In some preferred embodiments, the charging distance between the receiving coil 400 and the charging transmitter 500 is 10-20 cm.
[0030] Preferably, the distance between the charging transmitter 500 and the receiving coil 400 is 10-20cm. When the smart ring needs to be charged, simply bring the smart ring close to the charging transmitter 500. The smart ring can be charged remotely within 10-20cm of the charging transmitter, without the need to use a charging port to charge the smart ring. This reduces the risk of device damage caused by frequent plugging and unplugging of the charging port, and frees users from the constraints of cables, making charging more convenient.
[0031] In some preferred embodiments, the charging transmitter 500 includes a mouse pad 501, a transmitting coil 502 disposed within the mouse pad 501, and a power supply 503 electrically connected to the transmitting coil 502.
[0032] Preferably, when the smart ring is brought close to the charging transmitter 500, after the power is turned on, the transmitting coil 502 in the mouse pad 501 generates an alternating magnetic field around the transmitting coil 502 when the current passes through the transmitting coil 502. When the smart ring is brought close to the alternating magnetic field generated by the transmitting coil 502, the magnetic field passes through the receiving coil 400 and generates an induced electromotive force in the receiving coil 400, which eventually forms an induced current. After being processed by circuits such as rectification and voltage regulation, the induced current is converted into direct current, thereby charging the battery of the smart ring and realizing the wireless charging of the smart ring.
[0033] In some preferred embodiments, the smart ring can also be placed directly on the mouse pad 501 for charging, reducing the risk of device damage caused by frequent plugging and unplugging of the charging port and making charging more convenient.
[0034] In some preferred embodiments, the transmitting coil 502 is arranged circumferentially along the mouse pad.
[0035] Preferably, the transmitting coil 502 is a single coil, which is wound from the inside out along the circumference of the mouse pad. The structure of a single coil is relatively simple and the manufacturing process is not complicated, which can effectively control costs during mass production.
[0036] In some preferred embodiments, the smart ring also includes a flexible display screen 200 disposed on the surface of the battery mainboard 300 away from the receiving coil 400, and the flexible display screen 200 is electrically connected to the battery mainboard 300.
[0037] Preferably, the flexible display screen 200 is located on the battery motherboard 300. The flexible display screen 200 is a deformable and bendable display device made of flexible material. The flexible display screen 200 is placed on the battery motherboard 300 to display clear and vivid images or video content.
[0038] In some preferred embodiments, a ring casing 100 is also included, which is disposed on both sides of the battery motherboard 300 for wrapping the battery motherboard 300, and the flexible display screen 200 is disposed on the top of the ring casing 100.
[0039] Preferably, ring shells 100 are provided on both sides of the battery motherboard 300 to enclose the battery motherboard 300, and a flexible display screen 200 is provided on the top of the ring shells 100 to display clear and vivid images or video content for easy viewing.
[0040] The specific usage process of this utility model is as follows:
[0041] A flexible display screen 200 is placed on top of the battery motherboard 300. Ring shells 100 are placed on both sides of the battery motherboard 300 to cover it. A receiving coil 400 is placed on the surface of the battery motherboard 300 away from the flexible display screen. When the smart ring needs to be charged, there is no need to plug or unplug the charging cable. Simply place the smart ring 10-20cm away from the mouse pad or place it directly on the mouse pad 501 to start charging. Charging can also be achieved by placing the hand on the mouse pad 501 while wearing the ring. During work, direct charging can also be achieved by placing the hand on the mouse pad 501.
[0042] Working principle: When current passes through the transmitting coil 502 inside the charging transmitter 500, an alternating magnetic field is generated around the transmitting coil 502. When a smart ring equipped with a receiving coil 400 approaches this alternating magnetic field, the magnetic field passes through the receiving coil 400, generating an induced electromotive force in the receiving coil 400, and ultimately forming an induced current. After rectification and voltage regulation circuitry, the induced current is converted into direct current and stored on the battery motherboard, thus achieving wireless charging of the smart ring. This avoids the safety hazards that may arise from plugging and unplugging charging cables, such as electric shock and short circuits. It greatly improves the convenience of charging. The charging transmitter 500 is typically equipped with an intelligent control chip that can monitor the charging status in real time, ensuring the safety and reliability of the charging process.
[0043] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
