Description

charging device

The disclosure relates to a charging device, especially a charging device with a connector.

Smart mobile devices have become more and more popular, and because their functions are becoming more and more powerful, and they need to be thin and light to carry, the battery capacity is limited. In order to fear that their mobile devices will run out of power when they are outside, most people will carry another mobile power bank for emergency needs. But in order to connect the mobile power supply to the mobile device, you need to prepare another charging cable. If you forget to bring the charging cable, the mobile power supply will not work.

In order to solve this problem, there are currently also mobile power supplies in which the connector of the charging cable and the mobile power supply are integrated. There is no need to prepare additional charging cables when you go out. For this type of mobile power supply, for example, the connector directly protrudes from the mobile power supply casing, or a connecting line is assembled into the mobile power supply casing. If the connector directly protrudes from the power bank case, it will not only affect the appearance of the power bank, but also easily damage the connector due to collision during carrying or use. In addition, the connecting wire is used to fit the housing, and the connecting wire is easily affected by repeated pulling and pulling for a long time.

In view of the above, in one embodiment, the present disclosure provides a charging device including a casing, a battery, a connector, a first elastic member, an operating member, a first rotating member, a second rotating member and a second elastic member. The connector is movably accommodated or exposed to the casing, and is electrically connected to the battery. The first elastic member is disposed between the housing and the connector. The operating part is assembled in the housing and one end is exposed to the housing. The first rotating part is accommodated in the casing and is arranged corresponding to the operating part, and the first rotating part is located at one side of the connector and is suitable for limiting the connector. The second rotating part is accommodated in the casing, is located on the other side of the connector, and is suitable for limiting the connector. The second rotating member is linked to the first rotating member. The second elastic part is arranged between the casing and the second rotating part. When the operating part receives the pressing force along the first direction, the operating part pushes the first rotating part and drives the second rotating part to rotate, so as to release the limit connector, so that the connector moves along the second rotating part under the action of the first elastic part. Two directions are ejected from the casing. When the pressing force disappears, the second elastic member provides the rotating reset force of the second rotating member, and drives the first rotating member to rotate and reset, so as to limit the exposure of the connector to the housing. Wherein the first direction is perpendicular to the second direction.

Thus, the charging device of the present disclosure can operate the operating element exposed on the surface of the housing with one hand through the interlocking mechanism disposed inside the housing, so that the connector can be accommodated or exposed in the housing. When the charging device is to be used, as long as the operating part is pressed, the connector can be automatically ejected to charge the mobile device. Once used, the connector can be stored in the housing by pressing the operating part and the connector, so as to avoid damage to the connector during moving and storing. Moreover, the connector is accommodated in the casing, which can make the overall appearance more concise and beautiful.
