Description

Combined charger

Technical Field

The utility model relates to the technical field of vehicle chargers, in particular to a combined charger.

Background technique

The current car chargers are basically all-in-one machines, or split machines connected by wires. Both models have some common problems. The first is due to the limitation of product templates, such as some car chargers can only provide USB charging, or some car chargers can only provide cigarette lighter charging. It is impossible to arbitrarily combine chargers with different charging interfaces according to user needs, and the applicability is poor.

For example, the Chinese authorized patent with announcement number CN217935159U discloses an extended vehicle charger, including a vehicle charger body and a HUB electrically connected to the vehicle charger body through a spring wire, the front end of the vehicle charger body is provided with an AC conversion plug for plugging into the car cigarette lighter, the rear end of the vehicle charger body is provided with two charging interfaces, and the HUB is provided with 2 charging interfaces. The extended vehicle charger of the utility model adds a HUB, and the HUB is provided with 2 charging interfaces, thereby increasing the charging interface of the vehicle charger, which can meet the user's needs for charging multiple electronic products at the same time. Although the above patent can expand two charging interfaces on the basis of the vehicle charger body, when the number of charging ports required by the user exceeds four, it cannot be further expanded, that is, the above extended vehicle charger still does not have the function of arbitrarily combining chargers with different charging interfaces according to the needs of the user.

To this end, we propose a combined charger.
