This application claims the benefits of the Chinese Utility Model Application Serial Number 202121403513.9, filed on Jun. 23, 2021, the subject matter of which is incorporated herein by reference.
The present invention relates to a charging stand and, more particularly, to a charging stand having a plurality of recesses that are favorable to an engagement and having a rotatable connector.
A miniaturized electronic device, such as a portable audio device, is typically equipped with a rechargeable battery cell module. In this way, the devices can be used without connecting to a power supply. In addition, thanks to their small sizes, they can be portable devices.
Generally, while the electronic device is not being used, the users will connect it to a charging stand for charging it. The charging stand is provided with a connector, and the connector can be plugged into the electronic device and used to charge it. However, in the prior arts, when the charging stand is not connected to the electronic device, the connector is exposed to the outside, so the exposed connector looks very unsightly. In addition, when the charging stand is put in a carry-on bag, the exposed connector often punctures other objects and breaks their packages in the bag. Furthermore, the connector itself may be malfunctioned, deformed, or broken, when coming to a collision with a rigid object.
In addition, there are increasing demands to equip set-top boxes, Wi-Fi routers, or audio devices in vehicles. It is needed to fix these devices securely in the vehicles, particularly to let them face toward a certain direction, to obtain a better performance for receiving/transmitting electromagnetic wave or sound. However, the prior arts neither consider using the charging stand to provide the fixing mechanism to the electronic devices, nor even consider a method to charge the electronic devices in the vehicles.
Therefore, it is desirable to provide an improved charging stand to mitigate and/or obviate the aforementioned problems.
In this regard, one aspect of the present invention is to provide a charging stand includes a base, a housing, a circuit board, and a rotatable connector.
