Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle supporting equipment, and in particular to a fast charging interface component and an installation structure thereof. Background Art

[0002] The trend of fast charging and interface unification in consumer electronics is accelerating, and type-C is becoming more popular. Existing fast charging interface components (i.e. fast charging interface components) have already provided two interfaces, type-A and type-C. At the same time, the cable status of "power supply → power receiving" is: "type-A → type-C" and "type-C → type-C" coexist.

[0003] In the prior art, a dedicated chip is used to detect the protocol between the component and the "powered" device. When both interfaces are connected to the "powered" device, it is divided into "independently allocating protocol voltage and current to each of the two interfaces" and "switching both ports to 5V (5V is the USB bottom nominal voltage)". However, the use of dedicated chips will greatly increase the cost of fast charging interface components, and at the same time, it cannot guarantee fast charging of a single interface.

[0004] The current research and development direction of fast charging interface components must take into account both cost and fast charging functions, and must also be compatible with the "power supply → power receiving" cable status: "type-A→type-C" and "type-C→type-C" coexist.

[0005] To this end, we propose a fast charging interface component and its installation structure. Utility Model Content

[0011] Furthermore, the type-A plug hole and the type-C plug hole are parallel and interconnected.

[0012] Furthermore, the end cover comprises a cap, a panel and a sleeve portion extending backward from the peripheral edge of the panel, and the cap is hinged to the sleeve portion through a hinge and can be flipped and covered on the panel;

[0013] The box body comprises a box shell and a box cover which covers the upper opening of the box shell and is assembled with the box cover;

[0027] (III) Beneficial effects

[0028] The utility model provides a fast charging interface component and its installation structure, which has the following beneficial effects:

[0029] (1) Prevent type-A and type-C from being connected at the same time through a physical structure. Specifically, the distance between the two sockets is controlled. When the type male connector of the charging cable is inserted into any socket, the shell connected to the type male connector on the charging cable will partially block the other socket, making it impossible for the type male connector of the other charging cable to be inserted into the other socket. This eliminates the need for a dedicated chip to detect both ports at the same time, while supporting fast charging for both type-A and type-C. The coordination and power consumption are the same as when a dedicated chip is connected to a single interface, making it a very economical solution.

[0030] (2) The fast charging interface assembly is composed of a box cover and a box shell, the front end of the box body is fixed by the socket part of the end cover, and the rear end of the box body is fixed by the positioning hole / positioning slot of the installation box to prevent the box cover and the box shell from detaching. The box cover and the box shell are mainly vertically assembled by the ridge and groove structure. During the later maintenance process, it is convenient to open the box cover without damaging the connection structure between the box cover and the box shell, thereby improving the service life of the fast charging interface assembly.
