Description

Technical Field

[0001] The utility model relates to a new energy vehicle, in particular to a charging port self-checking device for a new energy vehicle. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. When new energy vehicles are charging, water can easily enter the charging port in extreme weather such as rain, resulting in the charging port being unable to charge and posing a safety hazard. Therefore, many manufacturers will test the charging ports of new energy vehicles before they leave the factory to ensure that the failure rate is reduced.

[0003] For example, CN115825604A discloses a charging port detection device suitable for electric vehicle production, but it is only for factory inspection of electric vehicles and cannot take into account hidden dangers such as charging port failures faced by new energy vehicles during daily use, which has limitations.

[0004] Therefore, there is currently a lack of a charging port self-check device that can perform self-checks on the AC charging port of a new energy vehicle during daily use, identify faults in advance to avoid risks such as being unable to charge in an emergency, and provide the driver with a better driving experience. Summary of the invention

[0007] The device is provided with a control module, the detection port of the control module is connected to the detection module through a wiring harness, and the control module is connected to and outputs a detection result signal to the automobile instrument and / or the central control screen.

[0008] The charging port cover is hinged on one side of the charging cavity through a rotating module, and the control port of the control module is connected to and outputs a control signal to the rotating module.

[0019] The following is a further detailed description of the specific implementation methods of the present invention, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0020] The self-test device of the charging port 3 is designed based on the existing vehicle charging structure. The current charging port 3 is generally arranged in a charging cavity on the side or front of the vehicle body 1. The charging cavity is a recessed cavity structure, and a charging port 3 for docking with the charging cavity is provided inside. A slow charging port 3 and a fast charging port 3 are provided in the charging cavity. A charging port cover 2 for sealing the charging cavity is hinged on one side of the charging cavity. It is preferred to adopt an electrically controlled opening and closing charging port cover 2 structure, that is, the charging port cover 2 is hinged on one side of the charging cavity through a rotating module 5. The rotating module 5 is a conventional electric rotating shaft. The control port of the control module is connected to and outputs a control signal to the rotating module 5. The control module can control the operation of the rotating module 5, that is, control the opening and closing of the charging port cover 2.

[0021] A telescopic module 4 is fixed on the inner side of the charging port cover 2 (the side facing the charging cavity when closed). The telescopic module 4 is a structure that can be telescopic. It is preferably controlled by an electric motor. One side of the telescopic module is fixed to the inner side of the charging port cover 2, and the other side is fixed to the structure that can be telescopic. The interface structure is the same as the charging gun structure that matches the charging port 3. The telescopic module 4 is in a retracted state under normal conditions. When the charging port cover 2 is closed, the telescopic module 4 in the retracted state separates the interface structure from the charging port 3. When the charging port cover 2 is closed, the telescopic module 4 in the fully extended state reliably connects the interface structure to the charging port 3. In order to facilitate separation, the interface structure and the charging port 3 do not have a matching locking structure, and the telescopic module 4 can be directly used to control the separation and connection of the two. The control port of the control module is connected to and outputs a control signal to the telescopic module 4. If a slow charging port 3 and a fast charging port 3 are provided in the charging cavity, each charging port 3 is provided with a matching interface structure and a detection module 6 on the charging port cover 2. At this time, two interface structures corresponding to the slow charging port 3 and the fast charging port 3 can be set on a telescopic module 4 at the same time, and the docking of the two charging ports 3 can be completed through one telescopic module 4, or the two interface structures can be fixed on two independent telescopic modules 4, and one of the interface structures can be docked with the charging port 3 according to the charging requirements.

[0022] The interface structure is provided with a detection module 6 electrically connected to the charging port 3, the detection port of the control module is connected to the detection module 6 through a wiring harness, and the control module is connected and outputs the detection result signal to the vehicle instrument and / or the central control screen. The control module is used for overall control, and can obtain the remaining power of the vehicle, control the switch of the charging port cover 2, obtain the detection signal of the detection module 6 for detection and judgment, issue detection instructions to let the detection module 6 perform preset operations according to the set program, report the fault status to the vehicle instrument or the central control screen, etc. The control module can be a chip independently set up by the device, or it can be an additional functional module developed on the chip used in the existing car.

[0023] The retractable module is integrated into the inner side of the charging port cover 2 and is internally connected to the detection module 6. When the rotating device rotates the charging port cover 2 into place, the telescopic device extends the detection unit into the charging port 3 to start detection. When detection is not needed, the detection unit retracts into the retractable module.

[0024] The timing for the control module to perform self-inspection can be preset as needed, or it can be used to issue self-inspection tasks. The corresponding operation module can be set in the central control screen for users to select operations. When the control module executes the operation again, the self-inspection operation can be automatically performed. It can be when it is found that the remaining power of the power battery is too low or when an instruction to open the charging port cover 2 is received, the charging port 3 starts self-inspection. For example, when the instruction to open the charging port cover 2 is received, the control module sends an instruction to control the rotation device to lock, and controls the telescopic module 4 to extend the detection unit into the charging port 3 to start detection and report the fault status to the control module. Then the telescopic module 4 is retracted, and the rotation module 5 opens the charging port cover 2, and the detection is completed.

[0025] The specific steps are as follows:

[0026] Step S01, start working;

[0027] Step S02, initializing the control module;

[0028] Step S03, the control module determines whether the battery is low or needs to be charged, if not, it returns to S02, otherwise it goes to step S04;

[0029] Step S04, issuing an instruction to control the rotation device to lock, and the telescopic module 4 releases the detection unit;

[0030] Step S05, start detection by detection module 6;

[0031] Step S06, the detection module 6 ends the detection after reporting the detection result.

[0032] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
