DETAILED DESCRIPTION

[0060] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0061] Reference Figure 1 , shows a schematic structural diagram of an embodiment of an automobile wiring harness self-diagnosis device of the present invention, and the automobile wiring harness self-diagnosis device may specifically include the following components:

[0062] The winding tape 100 having the graphene electrode 110 is suitable for winding around the outside of the automobile wiring harness 200;

[0063] The diagnostic component 300 is connected to the graphene electrode 110 to form a loop with the graphene electrode 110 ; it is used to detect the circuit state of the loop and determine the fault state of the automobile wiring harness 200 .

[0064] Graphene is a two-dimensional material composed of carbon atoms, with a single-layer hexagonal honeycomb lattice structure; it is conductive. A graphene electrode 110 is provided on the winding tape 100. The graphene electrode 110 can be formed by printing a graphene-based conductive ink on the winding tape 100. The winding tape 100 can be used as the first layer of the wiring harness wrapping, and is wrapped around the outside of the automotive wiring harness 200. The winding tape 100 wraps around the end of the wiring harness section to be tested (the electrical end) all the way to the location where the detection device is arranged, and different winding methods are used according to the sensitivity requirements of the detection. For example, Figure 2 , the sensitivity requirement is not high, and the flower wrapping method can be used. Figure 3 , high sensitivity requirements, or use a densely wrapped coating method.

[0065] The diagnostic component 300 can be connected to the graphene electrode 110 to form a loop with the graphene electrode 110, and then emit current in the loop. The graphene electrode 110 is used as a sensing detection part, and the circuit status such as the resistance size and the on-off condition in the loop is detected. According to different circuit states, the corresponding fault state of the automotive wiring harness 200 is determined.

[0066] The embodiment of the present invention uses the winding tape 100 of the graphene electrode 110 to wrap around the automobile wiring harness 200 for detection. When the coating layer is damaged or water enters, resulting in the risk of wear and tear or water corrosion, timely detection can be performed. Due to the flexibility of the graphene electrode 110, it is not easy to break due to bending. For automobile wiring harnesses 200 of any length and thickness, the required length of tape can be directly cut for coating, which improves the flexibility of use.

[0067] In an optional embodiment of the present invention, the winding tape 100 includes: the graphene electrode 110 and the substrate layer 120,

[0068] The graphene electrode 110 is coated on the substrate layer 120 .

[0069] In an embodiment of the present invention, the winding tape 100 may include a graphene electrode 110 and a substrate layer 120. The material of the substrate layer 120 is selected according to the requirements. The substrate layer 120 includes: an insulating tape, and the graphene electrode 110 is coated on the insulating tape.

[0070] The insulating tape may be made of polyvinyl chloride (PVC), cloth, etc. For the cloth-based tape, the cloth may be made of rayon, polyester cloth, wool-polyester cloth, etc. The graphene electrode 110 is coated on the substrate layer 120 by ink printing, so that the graphene electrode 110 can be fixed on the substrate layer 120.

[0071] In an optional embodiment of the present invention, the graphene electrode 110 extends along the length direction of the winding tape 100 .

[0072] In practical applications, the graphene electrode 110 extends along the length direction of the winding tape 100, that is, the graphene electrode 110 can match the length of the winding tape 100, so that in actual winding, when the length of the winding tape 100 is cut according to needs, the graphene electrode 110 can also be cut at the same time, so that the corresponding detection function can be realized in different wiring harness segments.

[0073] In an optional embodiment of the present invention, the graphene electrode 110 includes:

[0074] A main graphene-based conductive ink line 111, wherein the main graphene-based conductive ink line 111 is connected with the diagnostic component 300 to form the loop to determine the fault status of the automobile wiring harness.

[0075] The graphene electrode 110 may be composed of a main graphene-based conductive ink line 111, and the diagnostic component 300 detects the circuit to determine the fault state of the automotive wiring harness 200. The main graphene-based conductive oil extends along the length direction of the winding tape 100, and the main graphene-based conductive ink line 111 is thickened at a certain distance to form the graphene electrode 110.

[0076] In an optional embodiment of the present invention, there are at least two main graphene-based conductive ink lines 111, and the main graphene-based conductive ink lines 111 are arranged in parallel, one end of the two main graphene-based conductive ink lines 111 is connected through a conductor 113, and the main graphene-based conductive ink lines 111, the conductor 113 and the diagnostic component 300 are connected to form the loop;

[0077] If the diagnosis component 300 detects that the loop is in a disconnected state, it is determined that the fault state of the vehicle wiring harness 200 is a broken state.

[0078] When there are at least two main graphene-based conductive ink lines 111, the two main graphene-based conductive ink lines 111 are identically parallel, one end of the two main graphene-based conductive ink lines 111 are connected through the conductor 113, and the other ends of the two main graphene-based conductive ink lines 111 are commonly connected to the diagnostic component 300, so that the diagnostic component 300 forms a loop with the main graphene-based conductive ink lines 111 and the conductor 113; by detecting that the circuit state is that the loop is in a disconnected state, it can be determined that the fault state of the automotive wiring harness 200 is a broken state.

[0079] In one example of the present invention, reference may be made to Figure 4, the number of the main graphene-based conductive ink lines 111 is at least three, the at least three main graphene-based conductive ink lines 111 are connected to the diagnostic component 300, two of the at least three main graphene-based conductive ink lines 111 are first main graphene-based conductive ink lines 111, the remaining main graphene-based conductive ink lines 111 of the at least three main graphene-based conductive ink lines 111 are second main graphene-based conductive ink lines 111, the first main graphene-based conductive ink lines 111 are connected to the auxiliary graphene-based conductive ink lines 112 to form the loop;

[0080] The diagnostic component 300 determines whether the fault state of the automobile wiring harness 200 is a broken state and / or locates the broken position according to the resistance value of the loop.

[0081] like Figure 4 As shown, there are at least three main graphene-based conductive ink lines 111, namely Figure 5 The main graphene-based conductive ink line 111 labeled a, the main graphene-based conductive ink line 111 labeled b, and the main graphene-based conductive ink line 111 labeled c. The main graphene-based conductive ink line 111 labeled a and the main graphene-based conductive ink line 111 labeled c are connected by a conductor labeled e 113. The three main graphene-based conductive ink lines 111 can all be connected to the diagnostic component 300. Two of the three main graphene-based conductive ink lines 111 form a loop with the diagnostic component 300. Figure 5After the main graphene-based conductive ink line 111 labeled a and the main graphene-based conductive ink line 111 labeled c are connected to the wire labeled d, the other ends of the main graphene-based conductive ink line 111 labeled a and the main graphene-based conductive ink line 111 labeled c are connected to the diagnostic component 300 to form a loop. The component detects whether the main graphene-based conductive ink line 111 labeled a and the main graphene-based conductive ink line 111 labeled c are conductive to determine whether the electrode tape of this section of the wiring harness is worn and broken, thereby detecting whether the sheathing layer of this section of the wiring harness is damaged to form a broken state and / or locate the broken position. The diagnostic component 300 can also synchronously detect whether the main graphene-based conductive ink line 111 labeled b is conductive with the main graphene-based conductive ink line 111 labeled a and / or the main graphene-based conductive ink line 111 labeled c to determine whether water has entered this section of the wiring harness. If the wiring harness section is dry, the flannel part of the cloth-based tape is insulated, and the loop of the main graphene-based conductive ink line 111 labeled b and the main graphene-based conductive ink line 111 labeled a and / or the main graphene-based conductive ink line 111 labeled c is disconnected; if water enters this section of the wiring harness, the conductivity of the flannel at the water inlet increases, then the main graphene-based conductive ink line 111 labeled b and the main graphene-based conductive ink line 111 labeled a and / or the main graphene-based conductive ink line 111 labeled b are connected in the loop, the detection device detects the conduction information, the fault state of the automobile wiring harness is a broken state, and it is judged that there is a risk of water entering this section of the wiring harness.

[0082] In an optional embodiment of the present invention, the graphene electrode further includes:

[0083] A secondary graphene-based conductive ink line 112, wherein the secondary graphene-based conductive ink line 112 is connected to the primary graphene-based conductive ink line 111; the primary graphene-based conductive ink line 111, the secondary graphene-based conductive ink line 112 and the diagnostic component 300 form a loop.

[0084] In order to realize a variety of different detection functions in specific applications, the graphene electrode 110 may also include: an auxiliary graphene-based conductive ink line 112, the auxiliary graphene-based conductive ink line 112 is connected to the main graphene-based conductive ink line 111; the main graphene-based conductive ink line 111, the auxiliary graphene-based conductive ink line 112 and the diagnostic component 300 form a loop. The graphene electrode 110 can be composed of the main graphene-based conductive ink line 111 and the auxiliary graphene-based conductive ink line 112. In an example of the present invention, it can be referred to Figure 5, the number of the main graphene-based conductive ink lines 111 is at least four, the at least four main graphene-based conductive ink lines 111 are connected to the diagnostic component 300, two of the at least four main graphene-based conductive ink lines 111 are first main graphene-based conductive ink lines, the remaining main graphene-based conductive ink lines of the at least four main graphene-based conductive ink lines 111 are second main graphene-based conductive ink lines, the first main graphene-based conductive ink lines are connected to the auxiliary graphene-based conductive ink lines 112 to form the loop;

[0085] If the first main graphene-based conductive ink line and the second main graphene-based conductive ink line are in a conductive state as the circuit state, it is determined that the fault state of the automobile wiring harness 200 is a water ingress state.

[0086] like Figure 5 As shown, there are at least four main graphene-based conductive ink lines 111, namely Figure 5 The main graphene-based conductive ink line 111 is labeled a, the main graphene-based conductive ink line 111 is labeled b, the main graphene-based conductive ink line 111 is labeled c, and the main graphene-based conductive ink line 111 is labeled d. The auxiliary graphene-based conductive ink line 112 is connected between the main graphene-based conductive ink line 111 labeled b and the main graphene-based conductive ink line 111 labeled c. These four main graphene-based conductive ink lines 111 can be connected to the diagnostic component 300. The main graphene-based conductive ink line 111 labeled b and the main graphene-based conductive ink line 111 labeled c are the first main graphene-based conductive ink line, and the main graphene-based conductive ink line 111 labeled a and the main graphene-based conductive ink line 111 labeled d are the second main graphene-based conductive ink line. Wherein, in a dry state, the first main graphene-based conductive ink line and the second main graphene-based conductive ink line are not conductive due to insulation isolation.

[0087] The diagnostic component 300 can detect the resistance between the main graphene-based conductive ink line 111 labeled b and the main graphene-based conductive ink line 111 labeled c. If the harness end is damaged and the graphene-based conductor line on the winding tape 100 is broken, the resistance between the main graphene-based conductive ink line 111 labeled b and the main graphene-based conductive ink line 111 labeled c will increase. According to the resistance calculation formula, the ratio of the length of the tape between the damaged part and the main body of the detection device to the total length of the tape is equal to the ratio of the resistance value after damage to the resistance value in the undamaged state. Based on the proportional relationship, the specific location of the damage can be determined. If water enters the harness section, the cloth-based tape will conduct electricity at the water inlet, and the main graphene-based conductive ink line 111 labeled a and / or the main graphene-based conductive ink line 111 labeled d will be connected to the main graphene-based conductive ink line 111 labeled b and / or the main graphene-based conductive ink line 111 labeled c, and the resistance between the conductors of the main graphene-based conductive ink line 111 labeled b and the main graphene-based conductive ink line 111 labeled c will also decrease. At this time, the detection device can identify that water has entered this harness section. It can be seen that the diagnostic component 300 can locate the fault position and / or determine the fault state by detecting the resistance value of the loop.

[0088] In addition, you can also refer to Figure 6 , when there are three main graphene-based conductive ink lines 111, as Figure 6 The main graphene-based conductive ink line 111 labeled a, the main graphene-based conductive ink line 111 labeled b, and the main graphene-based conductive ink line 111 labeled c. The auxiliary graphene-based conductive ink line 112 is connected between the main graphene-based conductive ink line 111 labeled b and the main graphene-based conductive ink line 111 labeled c. These three main graphene-based conductive ink lines 111 can be connected to the diagnostic component 300. The main graphene-based conductive ink line 111 labeled b and the main graphene-based conductive ink line 111 labeled c are the first main graphene-based conductive ink line, and the main graphene-based conductive ink line 111 labeled a is the second main graphene-based conductive ink line. The diagnostic component 300 can detect the resistance between the main graphene-based conductive ink line 111 labeled b and the main graphene-based conductive ink line 111 labeled c. If the wire harness end is damaged, the graphene-based conductor line on the winding tape 100 is broken, and the resistance between the main graphene-based conductive ink line 111 labeled b and the main graphene-based conductive ink line 111 labeled c will increase. In an optional embodiment of the present invention, the auxiliary graphene-based conductive ink line 112 is connected to the main graphene-based conductive ink line 111 and has an angle.

[0089] The auxiliary graphene-based conductive ink line 112 is connected to the main graphene-based conductive ink line 111 and has an angle. Figure 7 As shown, the auxiliary graphene-based conductive ink line 112 and the main graphene-based conductive ink line 111 are vertically connected to each other.

[0090] In an optional embodiment of the present invention, there are at least two auxiliary graphene-based conductive ink lines 112 , and the auxiliary graphene-based conductive ink lines 112 are arranged along the length direction of the winding tape 100 .

[0091] You can refer to Figure 7 When there are at least two auxiliary graphene-based conductive ink lines 112, the auxiliary graphene-based conductive ink lines 112 are arranged along the length direction of the winding tape 100, so that loops can be formed accordingly according to different lengths, so that wire harnesses of different lengths can be detected. In addition, the auxiliary graphene-based conductive ink lines 112 can be thickened at intervals, which can improve the sensitivity of water ingress detection and facilitate the connection between the detection port of the diagnostic component 300 and the graphene electrode 110.

[0092] Furthermore, the auxiliary graphene-based conductive ink lines 112 are arranged at equal intervals along the length direction of the winding tape 100, and the interval is negatively correlated with the detection sensitivity. By setting auxiliary graphene-based conductive ink lines with different intervals, different detection sensitivities can be obtained, so that it is convenient to quantify the detection index based on the sensitivity of the winding tape 100, so that the winding tape 100 can be used to detect the wiring harness conveniently. Among them, the interval is negatively correlated with the detection sensitivity, that is, the smaller the interval, the higher the density of the auxiliary graphene-based conductive ink lines 112, and the higher the detection sensitivity. Conversely, the larger the interval, the lower the density of the auxiliary graphene-based conductive ink lines 112, and the lower the detection sensitivity.

[0093] It should be noted that the graphene base in the graphene-based conductive ink line in the embodiment of the present invention is the same as the graphene component currently commonly used as a conductive line.

[0094] In an optional embodiment of the present invention, the diagnostic component 300 includes:

[0095] A collection module 310, connected to the graphene electrode 110, forming a loop with the graphene electrode 110, and used for collecting the circuit state of the loop;

[0096] The electronic control unit 320 is connected to the acquisition module 310 and is used to determine the fault state of the automobile wiring harness 200 according to the circuit state.

[0097] like Figure 8 The diagnostic component 300 may include a collection module 310, which is connected to the graphene electrode, forms a loop with the graphene electrode 110, and detects the circuit state in the loop. The collection module 310 may be a multi-channel collection module 310, so that it can be connected to multiple graphene electrodes 110 at the same time to detect the states of multiple wire harnesses.

[0098] The electronic control unit 320 is connected to the acquisition module 310 and determines the fault state of the corresponding vehicle wiring harness 200 by receiving and analyzing the circuit state.

[0099] Furthermore, the diagnostic component 300 also includes:

[0100] The communication module 330 is connected to the electronic control unit 320 and is used to send the fault status.

[0101] The diagnostic component 300 may also include a communication module 330. The communication module 330 may be wired communication or wireless communication, such as using LIN (local area interconnection network), CAN (controller area network) and other commonly used wired communication protocol modules in the vehicle for communication; it may also be Bluetooth, Star Flash, WIFI (wireless network), ZigBee, 4G (fifth generation mobile communication technology), 5G (fourth generation mobile communication technology) and other types of wireless communication modules 330. The communication module 330 is connected to the electronic control unit 320 through the communication module 330, and the communication module 330 receives the fault status of the wiring harness and sends the fault status to a designated location to warn of the fault status. If it is transmitted to the vehicle controller by wireless or wired means, the controller will then warn the owner to go to a nearby service shop for maintenance in time. The warning can also be sent directly to the owner or a nearby service point by wireless means.
