[0047] like Figure 1-Figure 6 As shown, this embodiment provides a new energy vehicle charging device, including a vehicle body 10, and the vehicle body 10 has an exterior and an interior.

[0048] It should be noted that the terms “exterior” and “interior” are only used to describe the positional relationship, wherein the term “interior” refers to the hidden space inside the vehicle body 10 itself, rather than the internal seating space or storage space of the vehicle body 10 .

[0049] In some embodiments, the vehicle body 10 is provided with an electronic control unit, a charging window 101 and a flip cover 102 covering the charging window 101 from the outside of the vehicle body 10, the flip cover 102 is provided with a sensing switch 103, the sensing switch 103 is configured to convert a touch sensing signal into an electrical signal and transmit it to the electronic control unit, and the electronic control unit is configured to control the opening and closing of the flip cover 102 according to the electrical signal; in this way, the opening and closing of the flip cover 102 can be controlled by the touch sensing switch 103, and the operation is simple and convenient.

[0050] In some embodiments, the electronic control unit is associated with the central control system of the car to further enhance the operating experience.

[0052] This embodiment can avoid the defect of independent split charging guns being stored in the car and occupying space in the car through integration.

[0053] In some embodiments, in order to realize automatic winding and releasing of the line, a first motor 111 is further provided inside the vehicle body 10. The first motor 111 is controlled by an electronic control unit, and the output end of the first motor 111 is connected to the winding and releasing structure 110. The first motor 111 can drive the winding and releasing structure 110 to automatically release or wind up the line. Compared with an independent split charging gun, this embodiment does not require the charging cable to be taken out and placed, and the operation process is simple, which can enhance the user experience.

[0054] In some embodiments, in order to improve the convenience of operation, the flap 102 is rotatably connected to the body 10 via a rotating shaft, a second motor 112 is provided inside the body 10, the second motor 112 is controlled by an electronic control unit, and the output end of the second motor 112 is connected to the rotating shaft.

[0055] In some embodiments, a plug 107 is provided at one end of the charging cable 106 extending to the outside of the vehicle body 10, and a bracket 104 is provided in the charging window 101. One end of the charging cable 106 passes through the bracket 104 and extends to the outside of the vehicle body 10. The purpose of the bracket 104 is to limit the plug 107 to prevent the plug 107 from being dragged into the vehicle body 10 and unable to be removed during the line collection process. At the same time, the bracket 104 can also support the plug 107 after the line is collected.

[0056] In some embodiments, in order to facilitate the removal and placement of the plug 107, the bracket 104 is provided with a tapered opening 105, the charging cable 106 is connected to the tapered opening 105, and the plug 107 is a tapered structure matching the tapered opening 105. Through the tapered design, the plug 107 can be limited and inserted into the tapered opening 105 after the cable is retracted, so as to prevent the plug 107 from shaking or making noise during driving.

[0057] In some embodiments, a sensor may be provided on the tapered opening 105 to detect the plug 107 , so as to determine whether the plug 107 is fully recovered.

[0060] Example 2

[0061] like Figure 7 and Figure 8 As shown, this embodiment provides a new energy vehicle charging control method, which is implemented based on a new energy vehicle charging device described in Example 1, and the method includes the following steps:

[0062] Touch the induction switch 103, use the vehicle central control system to detect the vehicle status, and feed back the detection signal to the electronic control unit, and the electronic control unit determines whether the opening requirement of the flip cover 102 is met according to the detection signal;

[0063] If the conditions are met, the electronic control unit controls the flip cover 102 to open. After the flip cover 102 is fully opened, the wire retracting and releasing structure 110 releases the charging wire 106 to extend it until the charging wire 106 is fully extended.

[0064] The charging cable 106 is connected to the charging post 20 to complete charging.

[0065] In some embodiments, the step of touching the sensing switch 103, detecting the vehicle state using the vehicle central control system, and feeding back the detection signal to the electronic control unit, wherein the electronic control unit determines whether the opening requirement of the flip cover 102 is met according to the detection signal includes:

[0066] Determining whether the charging window 101 is in a closed state, and generating a first instruction;

[0067] determining whether the vehicle is in a non-driving state, and generating a second instruction;

[0068] Determining whether the vehicle is in an unlocked state, and generating a third instruction;

[0069] When the first instruction, the second instruction and the third instruction all meet the requirements, the electronic control unit generates an instruction to open the flip cover 102 .

[0070] That is, the second motor 112 works to drive the flip cover 102 to flip open. If any one of the first instruction, the second instruction and the third instruction does not meet the requirements, the electronic control unit does not generate an opening instruction for the flip cover 102, that is, the second motor 112 does not operate.

[0071] In some embodiments, an opening detection sensor is also provided on the flip cover 102, so that the electronic control unit can obtain the opening angle of the flip cover 102, so as to judge whether the flip cover 102 is fully opened according to the opening angle of the flip cover 102. After the flip cover 102 is fully opened, the first motor 111 drives the retractable wire structure 110 to release the wire to extend the charging wire 106 until the charging wire 106 is fully extended, and the plug 107 is connected to the charging pile 20 to start charging until the charging is completed.

[0072] In some embodiments, after charging is completed, the plug 107 and the charging post 20 are disconnected to facilitate subsequent cable collection.

[0073] In some embodiments, the control method further comprises the following steps:

[0074] After charging is completed, the induction switch 103 is touched to detect the vehicle status using the vehicle central control system, and the detection signal is fed back to the electronic control unit;

[0075] The electric control unit controls the wire retracting and releasing structure 110 to retract the wire according to the detection signal, and controls the flip cover 102 to close after the wire is retracted into place.

[0076] In some embodiments, the step of touching the sensing switch 103 after charging is completed, detecting the vehicle status using the vehicle central control system, and feeding back the detection signal to the electronic control unit includes:

[0077] Determine whether the charging window 101 is in a closed state; determine whether the vehicle is in a non-driving state; determine whether the vehicle is in an unlocked state; determine whether the plug 107 is not connected to the charging pile 20; when the above states all meet the requirements, the electronic control unit generates a wire-retracting instruction for the wire-retracting structure 110, and the first motor 111 drives the wire-retracting structure 110 to retract the charging wire 106 until the charging wire 106 is retracted into place, at which time the plug 107 is embedded in the tapered mouth 105.

[0078] In some embodiments, when the charging cable 106 is retracted into place, the electronic control unit generates a closing instruction for the flip cover 102 , and the second motor 112 drives the flip cover 102 to flip and close.

[0079] In summary, this embodiment provides a new energy vehicle charging control method, which can control the opening and closing of the flip cover 102 through the touch sensing switch 103, and can realize automatic wire release and wire retraction through the wire retracting structure 110. There is no need to take the charging gun from the car to the charging window to open the cover and plug it into the car charging window and then plug it into the charging pile, which simplifies the car charging operation process and improves customer experience; and when not charging, the charging cable can be hidden in the car without taking up space inside the car.

[0080] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
