Description

The present invention relates to a charging device for charging a wearable device.

Rechargeable batteries installed in portable devices typically must be replaced or recharged as soon as the power supply level to the electronic components becomes insufficient. The frequency with which such rechargeable batteries are replaced or recharged depends largely on the multiple functions that the device is to fulfill. In addition, wearable devices are known in which a wristband is provided with a charging terminal for a rechargeable battery as a simple means of electrically connecting to the rechargeable battery in order to recharge the rechargeable battery of a mobile device (for example, (See Patent Document 1).

Furthermore, wearable devices have recently been considered that are attached to a living body by a user and monitor the user's health condition by acquiring biological information such as an electrocardiogram, blood pressure, and pulse rate over a long period of time. Monitoring of a user's health condition using such a wearable device is required not only in medical facilities but also in daily life. Therefore, in order to prevent restrictions on a user's actions when wearing a wearable device, it is also required to make the wearable device smaller and lighter.

Patent No. 5428889

In the wearable device described above, it is necessary to charge the rechargeable battery of the wearable device with a charger while it is removed from a living body. However, when monitoring a user's health condition for a long time, the user needs to stop measuring biometric information and remove the wearable device from the living body every time the rechargeable battery built into the wearable device is charged. Therefore, during charging, biometric information of the user cannot be measured. For example, in order to use the wearable device for a long time, it may be possible to make the rechargeable battery larger, but this increases the size and weight of the wearable device, resulting in decreased wearability and restrictions on the user's actions. It is also possible to make the charger cable longer and charge the wearable device while wearing it, allowing the user to move within a designated area, but there is a limit to the length of the charger cable. , there is also the problem of restrictions on user behavior.
