[0030] In a first aspect, the present application provides a wiring harness assembly 10 for an engine. Figure 1 It is a schematic structural diagram of an embodiment of a wiring harness assembly 10 of an engine provided in the present application.

[0031] Combination Figure 1 The wiring harness assembly 10 of the engine includes a connecting harness 11, a first fixing member 12 and a second fixing member 13. The connecting harness 11 is connected to the controller of the vehicle and the sensor on the engine respectively. The first fixing member 12 and the second fixing member 13 are used to fix the connecting harness 11.

[0032] Specifically, the controller may be an ECU (Electronic Control Unit) of the vehicle, which receives the sensing data acquired by the sensor through the connecting harness 11, and further controls the engine and related components based on the sensing data. The number of the first fixing member 12 and the second fixing member 13 may be multiple, and the first fixing member 12 and the second fixing member 13 are different fixing members, and different fixing members can adapt to different fixing conditions, thereby achieving good fixing of the connecting harness 11 under different fixing conditions.

[0033] More specifically, the first fixing member 12 and the second fixing member 13 are both connected to the connecting harness 11, that is, they are both fixed to the connecting harness 11. The first fixing member 12 is provided with a snap-fit ​​hole 1223, and the snap-fit ​​hole 1223 is used for the first fixing structure of the engine to extend into to achieve snap-fit ​​fixation. The first fixing structure of the engine can be the structure of the engine itself, or it can be an additional fixing structure provided on the engine, and no specific limitation is made here. At this time, the first fixing structure is provided with a fixing protrusion 1222, and the fixing protrusion 1222 can extend into the snap-fit ​​hole 1223, and then be fixed in the snap-fit ​​hole 1223 by snapping, thereby achieving the connection and fixation between the first fixing member 12 and the first fixing structure.

[0034] As for the fixing method between the second fixing member 13 and the engine, the second fixing member 13 is provided with a snap-fitting protrusion 131, and the snap-fitting protrusion 131 is used to extend into the fixing hole of the second fixing structure of the engine to achieve snap-fitting fixation. Similarly, the second fixing member 13 can be a structure of the engine itself, or a structure attached to the engine, and no specific limitation is made here. The second fixing member 13 can be specially provided with a fixing hole for cooperating with the snap-fitting protrusion 131, so that the snap-fitting protrusion 131 can extend into the fixing hole to achieve snap-fitting fixation, thereby achieving the connection and fixation between the second fixing member 13 and the second fixing structure.

[0035] In summary, the wiring harness assembly 10 of the engine includes the first fixing member 12 and the second fixing member 13, so it can adapt to the fixing requirements under different working conditions, and thus can achieve a good fixing effect on the connecting harness 11. In addition, the first fixing member 12 and the second fixing member 13 are both fixed to the fixing structure on the engine by snapping, so the first fixing member 12 and the second fixing member 13 are easy to install and disassemble, and thus the installation and disassembly of the wiring harness assembly 10 of the engine is easy.

[0036] Continue to combine Figure 1 In some specific embodiments, the connection harness 11 includes a main harness 111 and a sub harness 112. The main harness 111 is connected to the controller, one end of the sub harness 112 is connected to the main harness 111, and the other end of the sub harness 112 is connected to the sensor. It should be understood that the number of main harnesses 111 can be one, and the number of sub harnesses 112 can be multiple, and multiple sub harnesses 112 are respectively connected to one main harness 111. At this time, the sensing signal received by the sensor is transmitted from the sub harness 112 to the main harness 111, and then transmitted from the main harness 111 to the controller.

[0037] Based on this arrangement of the connection harness 11, combined with Figure 1 , the main harness 111 can be fixed to the fixed structure of the engine through the first fixing member 12 and the second fixing member 13, and the sub-harness 112 is fixed to the second fixed structure through the second fixing member 13. At this time, the sub-harness 112 is only fixed by the second fixing member 13, and the second fixing member 13 can be a structure suitable for fixing the sub-harness 112. The main harness 111 is fixed by the first fixing member 12 and the second fixing member 13, which can be suitable for the specific fixing requirements of the main harness 111 under different fixing conditions.

[0038] Further integration Figure 1 In some specific embodiments, the wiring harness assembly 10 of the engine further includes a first connection terminal 14 and a second connection terminal 15, and the first connection terminal 14 and the second connection terminal 15 are different connection terminals. In this case, there are multiple sub-wiring harnesses 112, some of which are connected to the sensor through the first connection terminal 14, and the remaining sub-wiring harnesses 112 are connected to the sensor through the second connection terminal 15. Figure 1 In the figure, it is shown that there are five sub-harnesses 112, four of which are connected to the sensor via the first connection terminal 14, and one of which is connected to the sensor via the second connection terminal 15. It should be understood that the sensors connected to the first connection terminal 14 and the second connection terminal 15 are different sensors, and different sensing information is obtained through different sensors.

[0039] Continue to combine Figure 1In some specific embodiments, the wiring harness assembly 10 of the engine further includes a heat-insulating sleeve 16. The temperature of the area where the high-temperature wiring harness section of the connecting wiring harness 11 is located is higher than the preset maximum temperature. The heat-insulating sleeve 16 is set on the high-temperature wiring harness section to reduce the heat transfer of the engine to the high-temperature wiring harness section through the heat-insulating sleeve 16. It should be understood that the engine will generate more heat during operation. At this time, the temperature of some parts of the engine may be high. At this time, the wiring harness end of some connecting wiring harnesses 11 is in the high-temperature area. The wiring harness section in the high-temperature area can be called a high-temperature wiring harness section. Since the ambient temperature of the environment in which the high-temperature wiring harness section is located is high, when the temperature is higher than the preset maximum temperature, it means that the high-temperature wiring harness section may be greatly affected by the temperature and may even be damaged at high temperature. Therefore, this embodiment reduces the heat transfer by setting the heat-insulating sleeve 16, which can reduce the influence of high temperature on the high-temperature wiring harness section, thereby realizing the protection of the high-temperature wiring harness section. In some application scenarios, the heat-insulating sleeve 16 can be composed of aluminum foil tape.

[0040] Combination Figure 1 As well as the above content, a heat insulating sleeve 16 can be provided on both the main harness 111 and the sub harness 112. Moreover, the number of the heat insulating sleeves 16 is not limited to two. Through this arrangement, on the basis of achieving good protection for the connecting harness 11, the use of heat insulating materials can be reduced, thereby reducing costs. Among them, a layer of corrugated tube can be provided on the connecting harness 11, and then the corrugated tube can be used to achieve good protection of the harness assembly. At this time, the heat insulating sleeve 16 is provided on the corrugated tube.

[0041] Figure 2 yes Figure 1 A schematic diagram of the structure of the first fixing member 12 of the wiring harness assembly 10 of the engine, Figure 3 yes Figure 2 The schematic diagram of the structure of the first fixing member 12 in another viewing angle is shown. Figure 4 yes Figure 2 The side view of the first fixing member 12 is shown, Figure 5 yes Figure 4 The first fixing member 12 is shown in a cross-sectional view along the section line AA.

[0042] Combination Figure 2 as well as Figure 3 In some specific embodiments, the first fixing member 12 includes a first cylindrical portion 121 and a clamping portion 122. The first cylindrical portion 121 includes a fixed end 1211 and a movable end 1212. The movable end 1212 is clamped to the fixed end 1211 to form a first annular fixing hole 1213. The first annular fixing hole 1213 is used for the connecting wire harness 11 to pass through to fix the connecting wire harness 11. The clamping portion 122 is formed with a clamping hole 1223.

[0043] Among them, when the movable end 1212 of the first cylindrical portion 121 is not engaged with the fixed end 1211, the connecting wire harness 11 can be engaged into the first annular fixing hole 1213 through the connection between the fixed end 1211 and the engaging end, so that the movable end 1212 is engaged with the fixed end 1211 to achieve the stability of the structure of the first cylindrical portion 121. In order to better fix the connecting wire harness 11 in the first annular fixing hole 1213, the inner wall of the first annular fixing hole 1213 can be provided with limiting ribs 1214 along the circumference of the device, and the number of limiting ribs 1214 can be multiple, and the multiple limiting ribs 1214 can be arranged at intervals along the axial direction of the first annular fixing hole 1213.

[0044] Figure 6 yes Figure 2 A schematic diagram of the structure shown from its bottom perspective.

[0045] Combination Figure 2-Figure 6 In some specific embodiments, the engaging portion 122 includes a spring piece 1221 and a protrusion 1222 disposed on one side of the spring piece 1221. The spring piece 1221 is disposed in the engaging hole 1223, and the first fixing structure is provided with a positioning hole. When the first fixing structure is inserted into the engaging hole 1223, the protrusion 1222 is engaged in the positioning hole, so that the engaging portion 122 is engaged with the first fixing structure.

[0046] Specifically, one end of the spring sheet 1221 can be fixed to the inner wall of the engaging hole 1223, and the other end of the spring sheet 1221 can be exposed in the engaging hole 1223, so that the spring sheet 1221 can be elastically deformed. When the first fixing structure is inserted into the engaging hole 1223, the first fixing structure causes the spring sheet 1221 to be elastically deformed, so that the protrusion 1222 on one side of the spring sheet 1221 can be engaged in the positioning hole, so that the protrusion 1222 and the first fixing structure are relatively fixed, thereby achieving relative fixation between the engaging portion 122 and the first fixing structure.

[0047] Figure 7 yes Figure 1 Schematic diagram of the structure of the second fixing member 13.

[0048] Combination Figure 7 In some specific embodiments, the engaging protrusion 131 includes a column 1311 and a plurality of elastic protrusions 1312, the plurality of elastic protrusions 1312 are arranged relative to the side wall protrusions of the column 1311, and the plurality of elastic protrusions 1312 are arranged at intervals along the length direction of the column 1311. The column 1311 is arranged substantially in a columnar shape, and the column 1311 may include two opposite side walls, and the plurality of elastic protrusions 1312 may be respectively arranged on the two opposite side walls, and arranged at intervals along the length direction of the side walls.

[0049] Among them, the elastic protrusion 1312 has a certain elasticity, and can be elastically deformed. In the process of the engaging protrusion 131 penetrating into the fixing hole, the elastic protrusion 1312 is elastically deformed against the inner wall of the fixing hole, so that the elastic protrusion 1312 passes through the fixing hole. After the engaging protrusion 131 passes through the fixing hole, the top of the elastic protrusion 1312 is against the bottom wall of the second fixing structure. It should be understood that since a plurality of elastic protrusions 1312 are arranged at intervals in the length direction of the column 1311, when the fixing hole has different depths, different elastic protrusions 1312 can be against the bottom wall of the second fixing structure. For example, when the depth of the fixing hole is small, the elastic protrusion 1312 that is relatively high can be against the bottom wall of the second fixing structure.

[0050] Continue to combine Figure 7 In some specific embodiments, the second fixing member 13 includes a second cylindrical portion 132, the locking protrusion 131 is arranged at the bottom of the second cylindrical portion 132, the second cylindrical portion 132 includes a fixing belt 1321 and a limiting hole 1322, one end of the fixing belt 1321 is fixed and the other end passes through the limiting hole 1322 to form a second annular fixing hole, and the second annular fixing hole is used for allowing the connecting harness 11 to pass through to fix the connecting harness 11.

[0051] Specifically, the second cylindrical portion 132 may include a base 1323, one end of the fixing belt 1321 is fixed on the base 1323, and the limiting hole 1322 is provided on the base 1323. At this time, the diameter of the second annular fixing hole can be adjusted by setting the amount of the fixing belt 1321 passing through the limiting hole 1322, so that the second annular fixing hole can be matched with the connecting harness 11 of different diameters.

[0052] Continue to combine Figure 7 In some specific embodiments, the locking protrusion 131 also includes an elastic disc 133, and the top of the column 1311 structure extends downward from the bottom of the elastic disc 133. When the locking protrusion 131 passes through the fixing hole to achieve locking and fixing, the elastic disc 133 undergoes elastic deformation and abuts against the top wall of the second fixing structure.

[0053] In combination with the above, the elastic disc 133 can be arranged at the bottom of the base 1323, and the top of the engaging protrusion 131 can be connected to the central area of ​​the bottom wall of the elastic disc 133, so that the column 1311 structure extends downward from the bottom of the elastic disc 133. When the elastic protrusion 1312 abuts against the bottom wall of the second fixing structure, the elastic disc 133 is deformed and abuts against the top wall of the second fixing structure, so that the second fixing member 13 can be firmly fixed to the second fixing structure.

[0054] The second aspect of the present application provides a vehicle, which includes the wiring harness assembly 10 of the engine as in any of the above embodiments. For the specific description of the wiring harness assembly 10 of the engine, please refer to the contents of the above embodiments, and no further description will be given.
