Title: Quick positioning-charging device

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention provides a quick positioning-charging device, more particularly to an electrical connection structure in which a mobile electronic device can be elastically abutted with a power-terminal connector of a charging platform. 
     2. Description of the Related Art 
     In recent years, with rapid development of electronic technology and multimedia information, electronic products such as smart phones, tablet computers, and notebook computers are designed toward light, short, and powerful functions to have features of smaller size, lighter weight, and easy carry, and software and hardware of the electronic products are also continuously innovated, so that the electronic products can be used more flexibly and have improved practical effects, and become indispensable devices widely applied in people&#39;s work and life entertainment. 
     However, as the processing speed of the electronic product is improved, the mobile electronic device such as smart phone, tablet computer or notebook computer consumes more power. As a result, when a user operates a mobile electronic product while walking, the battery power of the mobile electronic device is quickly exhausted, and the user needs to find a power socket nearby to charge the battery of the mobile electronic device. 
     In teaching environment (for example, schools), in order to meet the requirement in digital teaching, teachers and students use mobile electronic devices, such as tablets or notebooks, to replace traditional books for knowledge transfer, so how to conveniently charge the mobile electronics becomes extremely important. Generally, a charging device, such as a charging cabinet or a charging car, can provide a plurality of AC sockets or DC charging sockets, such as USB sockets, disposed thereon to charge the plurality of mobile electronic devices through necessary chargers and charging lines. For example, there is an advance charging socket adopting a USB TYPE C interface and having a connector with an elliptical insertion hole, so that the mobile electronic device equipped with the above-mentioned connector can be charged without distinction between the front and back sides of the connector, thereby providing excellent convenience in charging operation. Furthermore, the USB TYPE C interface has a maximum output voltage of 20 volts (V), a maximum output current of 5 amps (A), and an output power higher than a traditional USB TYPE A interface. The size of the USB TYPE C interface can be smaller than that of the traditional USB TYPE A interface. The USB TYPE C interface can be mounted on a notebook computer to replace the traditional DC Jack, and have a size smaller than the traditional DC charging connector, and also be more practical than the traditional DC charging connector. Because of the above advantages, the charging transmission interface of the mobile electronic device has gradually been changed to the USB TYPE C interface. 
     The USB TYPE C interface has many advantages, but the tongue structure of the USB TYPE C connector is relatively light and fragile, so when the male plug connected to the power supply wire is frequently plugged and unplugged with the connector in the mobile electronic device, the power supply wire or the mobile electronic device connector is possibly damaged and cannot perform the charging function. Therefore, how to design a device for charging without plugging and unplugging with the connector, is a key issue in the industry. 
     SUMMARY OF THE INVENTION 
     In order to solve the conventional problems, the inventors develop a quick positioning-charging device according to collected data, multiple tests and modifications, and years of experience in the industry. 
     An objective of the present invention is to provide a quick positioning-charging device. In the quick positioning-charging device, a charging platform includes a plurality of power-terminal connectors which each comprises a plurality of probe terminals, an insulating body and a female socket. The female socket is electrically connected to a power terminal. The quick positioning-charging device includes a plurality of accommodation frames assembled on the charging platform, and each accommodation frame includes an accommodation space configured to accommodate a mobile electronic device. A male plug on a side of an isolating member of a charging-terminal connector can be plugged with a charging hole of the mobile electronic device to form electrical connection. The charging-terminal connector comprises a plurality of contact points configured to elastically abut with the plurality of probe terminals of the power-terminal connector for forming electrical connection. The electrical connection structure of the mobile electronic device elastically abutted with the power-terminal connector of the charging platform can prevent the male plug connected to the power supply cable of the charging device from being frequently plugged and pulled with the connector of the mobile electronic device, thereby solving the conventional problem of the connector of the power supply cable or mobile electronic device being possibly damaged by the frequent plug-pull operations. As a result, the charging device of the present invention has advantages of quick positioning and convenient use. 
     Another objective of the present invention is that the accommodation frame can comprise a first partition plate and a second partition plate, the second partition plate has a plurality of side hooks disposed at a bottom thereof and configured to buckle a plurality of buckle grooves which correspond in position thereto and are formed on a bottom plate of the first partition plate, and the first partition plate has at least one locking plate disposed on a side thereof and having a locking hole, and a fastener can be inserted into the locking hole and fixed in a side wall of the charging platform. The bottom plate of the first partition plate includes a plurality of bottom hooks disposed on a bottom thereof and configured to buckle into a plurality of buckle holes which correspond in position thereto and are formed on a base plate of the charging platform, so as to fix the accommodation frame with the charging platform and form the accommodation space between the first partition plate and the second partition plate. 
     Another objective of the present invention is that the first partition plate and the second partition plate have two guiding grooves formed on opposite two inner sides, respectively, and a position-limiting block has sliding tracks formed on two opposite sides thereof and slid along and positioned in the two guiding grooves, and when a mobile electronic device with a smaller size is placed into the accommodation space, the position-limiting block can abut against and position the mobile electronic device in a vertical direction, so as to prevent the mobile electronic device from shaking and sliding.
