In the receiving state, the movable member 41 is located in the notch portion 14, which can effectively hide and protect the movable member 41, reduce the occupied volume of the vehicle-mounted charging support 1, improve the reliability and improve the appearance.

[0036] Specifically, the first rotating shaft 412 and the second rotating shaft 413 are separately arranged on opposite sides of the main body 411, the other ends of the first rotating shaft 412 and the second rotating shaft 413 are connected to the notch portion 14, and the axes of the first rotating shaft 412 and the second rotating shaft 413 coincide. The elastic member 43 is sleeved on the first rotating shaft 412, one end of the elastic member 43 is connected to the main body 411, and the elastic member 43 is specifically a leaf spring. When the main body 411 rotates, the elastic member 43 is compressed or released. Specifically, in the embodiment, when the movable member 41 is in the supporting state, the elastic member 43 is in the released state; when the movable member 41 is rotated to be located in the notch portion 14, the elastic member 43 is compressed; when the movable member 41 is in the receiving state, the elastic member 43 is always in the compressed state; when the movable member 41 needs to be in the supporting state, the locking member 42 is released, and then the movable member 41 is ejected to the supporting state from the receiving state under the elastic force of the elastic member 43.
