DETAILED DESCRIPTION

[0022] The utility model will be further described in detail through the drawings and examples.

[0023] As Figures 1-2 shown: a sealed electric vehicle adapter box, including front protective cover 1: with main shell 3 front part forms sealed box body, protects charging socket 4;Upper protective cover 2: it has sealing rubber strip one 22 on it, with main shell 3 forms sealed cavity, protects internal electronic device;Main shell 3: for installation and protection device.

[0024] The main shell 3 of the adapter box is divided into two communicating cavities, both of which have good sealing property and structural strength. The cavity is provided with a charging socket 4 and a front protective cover 1, which can protect the charging socket 4. The cavity is internally provided with electrical elements such as a relay 8 and a high-voltage control panel 10, and is provided with an upper protective cover 2, which can realize charging process control and supply power to the electronic power unit of the whole vehicle.

[0025] The adapter box utilizes the closed space formed by the charging socket 4, the main shell 3, the upper protective cover 2, the high-voltage socket one 5 and the high-voltage socket two 6, and can flexibly integrate electrical elements that are incompatible with the battery and PEU of the whole vehicle, such as the relay 8, the high-voltage control panel 10, the high-voltage socket one 5 and the high-voltage socket two 6, thereby playing a protective role and realizing the intermediate adapter role of fast charging and power supply.

[0026] Referring to FIG. 1, Figure 3 The bottom of the upper protective cover 2 is provided with a ring of blocking blocks 21, which are matched with the inner ring size of the upper opening of the main shell 3 and are embedded therein after being closed. Since there is a slight gap between the blocking blocks 21 and the upper opening of the main shell 3 when the blocking blocks 21 are embedded, the sealing degree is poor. A ring of sealing rubber strips one 22 is additionally provided at the bottom of the upper protective cover 2, which is tightly attached to the inner side of the blocking blocks 21. In addition, the bottom end of the sealing rubber strips one 22 is lower than the bottom end of the blocking blocks 21 and expands outward to be squeezed apart. The sealing rubber strips one 22 further seal the gap between the upper opening of the main shell 3 and the blocking blocks 21. The sealing rubber strips one 22 are made of high-elastic rubber, and the blocking blocks 21 can better confine and embed the sealing rubber strips one 22 in the main shell 3.

[0027] Referring to FIG. 1, Figure 2 The main shell 3 is provided with a convex cover 04 that forms a protective cover with the front protective cover 1. The inner ring of the convex cover 04 is recessed to form a recessed groove 02. The inner side of the front protective cover 1 is provided with a matching block 03 that is matched with the size of the inner wall and can be completely placed in the convex cover 04. The matching block 03 is surrounded by a ring of sealing rubber strips two 01, which are used for sealing when being placed in the recessed groove 02.

[0028] Referring to FIG. 1, Figures 4-5 Further, the recessed groove 02 is provided with a ring of sunken embedding grooves 05 at the periphery, and the sealing rubber strips two 01 are designed to have a U-shaped cross section, so that the sealing gasket can be entirely squeezed into the embedding grooves 05. In addition, the contact between the sealing rubber strips two 01 and the convex end face can also increase the secondary sealing.

[0029] As shown in FIG. 1, Figures 1-7The shown: charging socket 4: with sealing gasket, installed on the main shell 3, play a sealing and fast charging effect. At the same time the tail for copper row structure, suitable for integrated in the shell and relay 8 connection. High voltage socket one 5: output current to the vehicle battery. High voltage socket two 6: output current to electronic power unit. Low voltage socket 7: output low voltage detection signal. Relay 8: control charging circuit break. Conductive copper row 9: connecting charging socket 4, relay 8 and high voltage socket one 5, high voltage socket two 6, for conductive. High voltage control board 10: control relay 8 switch.

[0030] The main shell 3 integrated with the vehicle battery and electronic power unit has been shaped relay 8, high voltage control board 10 etc. (the upper power unit), play the role of intermediate adapter.

[0031] Charging branch working process: when inserting the charging gun, high voltage control board 10 control relay 8 on, high voltage socket one 5 output current to the vehicle battery, realize the function of charging. Power supply branch working process: high voltage socket two 6 connection vehicle battery, through the adapter box inside the copper row and high voltage socket one 5, high voltage socket two 6, to the vehicle PEU power supply.

[0032] Referring to the accompanying Figure 8 The shown, high voltage principle: charging work, only from the charging socket 4 to the power battery power supply. Charging is completed and the vehicle starts to work, the power battery to PEU power supply.

[0033] Specific structure: charging socket 4 with sealing gasket, installed on the adapter box main shell 3, with sealing strip of the upper protective cover 2, high voltage socket one 5, high voltage socket two 6, low voltage socket 7 together form a closed cavity. Internal installation relay 8, conductive copper row 9, high voltage control board 10. The above combination of devices, form two charging and power supply branch, and can be internally controlled break, output low voltage signal and high voltage current.

[0034] The above described according to the example for the inspiration, through the above description, the relevant staff can be in the range of not deviating from the idea of the invention, a variety of changes and modifications. The use of new technology range is not limited to the content of the specification, must be determined by the scope of claims to determine the scope of protection.
