Abstract

The invention belongs to the technical field of antennas, and provides an external power supply device applied to wearable devices, including a casing, a battery disposed in the casing, and a charging and discharging interface electrically connected to the battery. The external power supply The device also includes an antenna branch provided on the housing for coupling with the local antenna of the wearable device, and an antenna interface coupled with the antenna branch and used for communication with the wearable device . When the wearable device is docked and charged with an external power supply device, it can provide an external antenna branch coupled with the local antenna for the wearable device. The antenna branch can increase the height of the local antenna to the ground, which is a good improvement Antenna radiation efficiency of wearable devices.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a power supply device and a portable device applied to wearable devices. Background technique [0002] Smart wearable devices, such as smart watches and smart bracelets, have the advantages of being easy to carry, capable of quickly sensing needs and monitoring human health conditions in a timely manner. The market demand is increasing day by day, but the functions of smart wearable devices continue to increase, resulting in faster power consumption, and the issue of battery life needs to be paid attention to. At present, in order to solve the battery life problem, an external battery charging device is used to charge the watch. However, the introduction of an external battery has a huge impact on the performance of the antenna, which greatly weakens the ability to transmit and receive signals. As a result, the watch cannot receive calls normally due to poor signal ...
