wireless charging pack

technical field

The utility model relates to the technical field of handbags, in particular to a wireless charging bag.

Background technique

With the improvement of the quality of life, people rely more and more on smart mobile devices, such as smart phones, tablet computers, kindles, etc. However, due to technical limitations, the power storage capacity of existing smart mobile devices is quite limited. For example, for a mobile phone, the battery can last for 4 to 5 hours in call mode and two days in standby mode. In daily life, smart mobile devices often stop working due to low power. In addition to being an inconvenience, a dead battery can be very dangerous in emergencies or remote areas.

Currently, conventional methods of charging mobile devices typically involve plugging the mobile device into an electrical outlet with a power cord. However, it can be difficult to find power outlets in restaurants or during outdoor sports. Additionally, users may not be able to sit at a power outlet for long periods of time waiting for a smart mobile device to charge. In other words, many current charging methods are stationary, not allowing users to charge mobile devices without a power outlet. With the advent of wireless charging technology, wireless charging devices for smart mobile devices are gradually becoming popular, but most wireless charging devices are also fixed-point.

With the continuous improvement of people's living and consumption levels, various bags have become indispensable accessories around people. Therefore, some manufacturers have combined wireless charging devices with bags to design wireless charging handbags, such as the existing patent, a wireless charging handbag (public number: CN205568154U), which includes a bag body, the inner side of the lower side wall of the bag body There is a first receiving module for wireless charging and a rechargeable battery connected to the first receiving module. The bag body is located on the inner side of the rear side wall and is provided with a second inner bag for placing mobile phones for wireless charging. It also includes a wireless charging transmitting base. The wireless charging transmitting base is provided with a first transmitting module matched with the first receiving module, and a positioning device is provided between the wireless charging transmitting base and the lower side wall of the bag body. In view of the fact that the existing wireless charging methods are all in the form of a single individual, it is necessary to find a position to align with the transmitting port to achieve charging. However, the wireless charging module in the above patent is set in a bag, and the bag is made of cloth, causing the mobile phone to be charged. At the same time, the combination of known wireless charging packs is basically non-modular, and the battery core and wireless charging transmitter coil are not in the same position, which leads to the need for wiring inside the pack. Charging efficiency and loss improve.
