Description

A cradle for mounting a smart device and a battery coupled thereto {CRADLE FOR MOUNTING SMART DEVICE AND BATTERY COUPLED THERETO}

The present invention relates to a cradle holding a smart device and a battery coupled to the cradle.

With the development of information and communication technology and the recent trend in which non-face-to-face ordering is attracting attention, restaurants and other stores are increasingly taking orders from customers using smart devices such as tablet PCs. In general, a tablet PC is provided at each table of a restaurant or other store, and customers see a screen displayed on the tablet PC, log in, register a coupon, order food, pay for an order, and the like.

Examples of using tablet PCs in restaurants and other stores include cases where the tablet PC is simply placed on a table, when the tablet PC is simply mounted on a cradle, and the tablet PC is placed on the cradle and the tablet device is charged through the cradle at the same time. There are cases where this does not happen. Among these, when the tablet PC mounted on the cradle is charged through the cradle, it is the most convenient because the tablet PC is collected from the table one by one to be charged, and the trouble of placing the charged tablet PC on the table again can be saved. it will be a plan

However, looking at the conventional case in which tablet PCs are charged through a cradle, it is inconvenient to insert power plugs into the cradle one by one, and to charge multiple tablet PCs, multiple power plugs must also be provided. There is a problem that the management of the plug is very difficult.
