[0037] A wiring harness assembly 100 for a vehicle according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0038] Reference Figure 1 and Figure 2 As shown, a wiring harness assembly 100 for a vehicle according to an embodiment of the present invention may include: a wiring harness body 10 and a plurality of (greater than or equal to two) fixing members 20 .

[0039] Specifically, a plurality of fixing members 20 are arranged at intervals along the length direction of the wiring harness body 10, and the plurality of fixing members 20 are connected to the wiring harness body 10. The wiring harness body 10 can be fixed by the plurality of fixing members 20, so that the wiring harness body 10 can be fixed at a desired position, ensuring that the wiring harness body 10 is fixed reliably. For example, the wiring harness can be a double-strand high-voltage wiring harness.

[0040] In addition, if Figure 1 and Figure 2 As shown, the wiring harness body 10 between any two adjacent fixings 20 is formed into a free section 11, and the length of the free section 11 is less than or equal to 150 mm. Therefore, when the wiring harness body 10 is subjected to vibration, the wiring harness body 10 can remain relatively stable by having multiple fixings 20 spaced relatively close to each other, effectively reducing the transmission of vibration, and improving the vibration isolation effect of the wiring harness body 10, thereby reducing the vibration transmitted to other structures through the wiring harness body 10, ensuring the comfort and performance stability of the vehicle, and improving the user experience. For example, in some specific embodiments, the length of the free section 11 can be 150 mm, 140 mm, 130 mm, 120 mm, 110 mm, 100 mm, etc.

[0041] According to the wiring harness assembly 100 for a vehicle of the embodiment of the utility model, a plurality of fixing members 20 are arranged at intervals along the length direction of the wiring harness body 10 and connected to the wiring harness body 10, and the wiring harness body 10 between any two adjacent fixing members 20 forms a free section 11, and the length of the free section 11 is less than or equal to 150 mm, so that the plurality of fixing members 20 can reliably fix the wiring harness body 10, ensuring that the wiring harness body 10 remains relatively stable, effectively reducing the transmission of vibration, improving the vibration isolation effect of the wiring harness body 10, and ensuring the comfort and performance stability of the vehicle.

[0042] In the embodiment of the present utility model, the specific structure of the fixing member 20 can be set according to actual conditions.

At the same time, the vibration on the wire harness body 10 can be absorbed and weakened by the bushing 21, and the connection between the wire harness body 10 and other structures on the vehicle is isolated, so as to reduce the vibration on the wire harness body 10 from being transmitted to other structures, and improve the comfort of the vehicle.

[0044] In addition, if Figure 3-Figure 7 As shown, the fixing member 20 further includes a bracket 22 , which is sleeved on the bushing 21 . The bracket 22 blocks the opening 212 , thereby preventing the wiring harness body 10 from slipping out through the opening 212 , and ensuring a reliable connection between the wiring harness body 10 and the fixing member 20 .

[0045] In some embodiments, the bushing 21 can be a rubber part. The bushing 21 of the rubber part can effectively absorb the vibration on the wiring harness body 10 and prevent the vibration from being further transmitted, so that the fixing part 20 has a good vibration isolation effect on the wiring harness body 10, ensuring the comfort and performance stability of the vehicle, and is easy to process and manufacture, which is conducive to reducing production costs.

[0046] In some embodiments, Figure 3-Figure 6 , Figure 8 As shown, the wire harness body 10 includes a plurality of wire harnesses, and the through holes 211 may be a plurality of through holes 211 corresponding to the plurality of wire harnesses one by one. The plurality of through holes 211 can meet the fixing requirements of the plurality of wire harnesses, thereby ensuring reliable fixing.

[0047] In the embodiment of the present invention, the number of the via holes 211 can be flexibly set according to actual conditions. For example, the via holes 211 can be Figure 3 Two are shown, which can meet the fixing requirements for the double-strand high-voltage wire harness, or the number of vias 211 can also be three, four, five, six or more, which are all within the protection scope of the present utility model.

[0048] It should be noted that, for the convenience of description, the directions such as "front and rear direction" and "left and right direction" in the present invention are based on the direction relationship shown in the drawings, and are not limitations on the directions in actual application.

[0049] According to some embodiments of the present invention, Figure 3-Figure 6 , Figure 8 As shown, the bushing 21 includes a connecting portion 213 and a limiting portion 214. The connecting portion 213 has a length direction (for example Figure 4The two ends of the connecting portion 213 (left and right directions shown in the figure) are respectively provided with limiting parts 214, the limiting parts 214 extend in the circumferential direction of the connecting portion 213, the through hole 211 is penetrated through the connecting portion 213 and the limiting parts 214, the bracket 22 is sleeved between the two limiting parts 214, the bracket 22 can be limited by the two limiting parts 214, and the bracket 22 is prevented from being separated from the bushing 21, ensuring that the bushing 21 and the bracket 22 are reliably matched, and the structure of the bushing 21 is simple, which is convenient for processing and manufacturing.

[0050] In some embodiments of the present invention, Figure 5-Figure 7 As shown, a mounting groove 221 is formed on the bracket 22, and the mounting groove 221 has an open mouth 222. The connecting portion 213 is located in the mounting groove 221, so that the connecting portion 213 can be installed in the mounting groove 221 through the open mouth 222, thereby realizing the connection between the bracket 22 and the bushing 21, and the width of the open mouth 222 is smaller than the width of the connecting portion 213, which can prevent the bushing 21 from escaping from the open mouth 222, thereby ensuring that the bushing 21 is reliably fixed on the bracket 22, and at the same time, the bottom wall of the mounting groove 221 is opposite to the opening 212, thereby ensuring that the opening 212 is reliably blocked, thereby preventing the wiring harness body 10 from escaping from the opening 212.

[0051] In addition, if Figure 4 , Figure 6 and Figure 7 As shown, the bracket 22 is provided with through holes 223 at the two opposite ends of the open mouth 222, and the cable ties 23 can be passed through the through holes 223 to fix and tighten the bracket 22 at the two opposite ends of the open mouth 222, further preventing the bushing 21 from falling out of the open mouth 222, ensuring a reliable connection between the bracket 22 and the bushing 21, and avoiding problems such as deformation of the connecting part 213 and unreliable assembly caused by the wiring harness body 10 of different diameters passing through the through hole 211, thereby facilitating the versatility of the fixing part 20.

[0052] According to some embodiments of the present invention, Figure 6 and Figure 8 As shown, the connecting portion 213 is provided with a guide groove 215, the guide groove 215 is opposite to the through hole 223, and the guide groove 215 is along the width direction of the opening 222 (for example Figure 3 The guide groove 215 extends in the front-to-back direction as shown in the figure, and the cable tie 23 passing through the through hole 223 can be guided and positioned to avoid the problem of unreliable fixation caused by the deviation of the cable tie 23, and is conducive to improving the installation efficiency.

[0053] For example, in some embodiments, the wiring harness body 10 is fixed in the through hole 211 through the opening 212, the bushing 21 is clamped in the mounting groove 221 through the open mouth 222, the bottom wall of the mounting groove 221 is opposite to the opening 212, and a cable tie 23 is used to pass through the through hole 223 and the guide groove 215 to achieve the connection between the fixing member 20 and the wiring harness body 10.

[0054] In some embodiments, the maximum length of the bushing 21 is 40 mm-50 mm, so that the length of the bushing 21 is small, thereby reducing the space required for the length of the bushing 21, making the structure compact and the space constraint strong, and improving the structural mode and stiffness of the bushing 21, reducing the vibration and noise response, and improving the comfort of the vehicle. For example, in some specific embodiments, the maximum length of the bushing 21 can be 40 mm, 42 mm, 43 mm, 45 mm, 48 mm, 50 mm, etc.

[0055] In some embodiments, the maximum width of the bushing 21 is 50 mm-60 mm, so that the width of the bushing 21 is small, thereby reducing the space required for the width of the bushing 21, making the structure compact and the space constraint strong, and improving the structural mode and stiffness of the bushing 21, reducing the vibration and noise response, and improving the comfort of the vehicle. For example, in some specific embodiments, the maximum width of the bushing 21 can be 50 mm, 52 mm, 53 mm, 55 mm, 58 mm, 60 mm, etc.

[0056] In some embodiments, the maximum height of the bushing 21 is 20 mm to 30 mm, so that the height of the bushing 21 is small, thereby reducing the space required for the height of the bushing 21, making the structure compact and the space constraint strong, and improving the structural mode and stiffness of the bushing 21, reducing the vibration and noise response, and improving the comfort of the vehicle. For example, in some specific embodiments, the maximum height of the bushing 21 can be 20 mm, 22 mm, 23 mm, 25 mm, 2 mm, 30 mm, etc.

[0057] For example, in some embodiments, the fixing member 20 may be a cable tie 23 or a pipe clamp 24, both of which can fix the wiring harness body 10, can meet different usage requirements, and have a simple structure, which is conducive to reducing production costs.

[0058] The vehicle according to the utility model includes a vehicle body 30 and a wiring harness assembly 100 for a vehicle according to an embodiment of the utility model, and a part of the fixing member 20 is connected to the vehicle body 30, so that the wiring harness body 10 can be fixed on the vehicle body 30, meeting the fixing requirements of the wiring harness body 10. At the same time, by making the length of the free section 11 less than or equal to 150 mm, the vibration transmitted to the vehicle body 30 through the wiring harness body 10 can be reduced, thereby avoiding transmission to the vehicle's cockpit, ensuring the comfort and performance stability of the vehicle, and improving the user's experience. For example, the vehicle can be a hybrid vehicle, etc.

[0059] Since the wiring harness assembly 100 for a vehicle according to the embodiment of the utility model has the above-mentioned beneficial technical effects, the vehicle according to the embodiment of the utility model is arranged at intervals along the length direction of the wiring harness body 10 through multiple fixings 20 and connected to the wiring harness body 10, and the wiring harness body 10 between any two adjacent fixings 20 is formed into a free section 11, and the length of the free section 11 is less than or equal to 150 mm, so that the multiple fixings 20 can reliably fix the wiring harness body 10, ensure that the wiring harness body 10 remains relatively stable, effectively reduce the transmission of vibration, improve the vibration isolation effect of the wiring harness body 10, and ensure the comfort and performance stability of the vehicle.

[0060] In some embodiments where the fixing member 20 includes a bushing 21 and a bracket 22, such as Figure 3-Figure 7 As shown, the bracket 22 is provided with a flange 224, which is bent in a direction away from the bushing 21, and the flange 224 is connected to the vehicle body 30, which can achieve the connection requirement between the fixing part 20 and the vehicle body 30 and avoid the flange 224 interfering with the installation of the bushing 21. The bracket 22 has a simple structure and is easy to process and manufacture.

[0061] In some embodiments of the utility model, the vehicle also includes a powertrain and a power battery. The two ends of the wiring harness assembly 100 in the length direction are respectively connected to the powertrain and the power battery, which can realize the connection requirements between the powertrain and the power battery and meet the required usage requirements. For example, the power battery can transmit electrical energy to the powertrain through the wiring harness assembly 100, or the powertrain can charge the power battery through the wiring harness assembly 100.

[0062] In addition, the remaining fixing part 20 is connected to the powertrain, which can realize the connection between the wiring harness assembly 100 and the powertrain, ensuring that the wiring harness assembly 100 is reliably fixed in the vehicle. At the same time, by making the length of the free section 11 less than or equal to 150 mm, the vibration transmitted from the powertrain to the vehicle body 30 through the wiring harness body 10 can be reduced, thereby avoiding transmission to the cockpit, ensuring the comfort and performance stability of the vehicle, and improving the user experience.

[0063] Specifically, in order to prevent the vibration frequency of the harness body 10 from coinciding with the excitation frequency of the engine of the powertrain, that is, to prevent the harness body 10 from resonating, it is necessary to control the vibration frequency of the harness body 10 to avoid the excitation frequency of the engine, thereby avoiding resonance.

[0064] Therefore, according to the natural frequency formula of the flexible structure:

[0065]

[0066] Among them, f nis the nth order frequency of the harness body 10, in Hz; l is the length of the harness body 10, in m; n is a constant; T is the restraint tension of the harness body 10, in N; ρ is the density of the harness body 10, in kg / m 3 ; A is the cross-sectional area of ​​the harness body 10, in m 2 .

[0067] Since the shorter the length of the harness body 10 is, the greater the natural frequency is, according to the main order excitation frequencies corresponding to each speed of the engine, details are shown in Table 1 below.

[0068]

[0069]

[0070] Table 1

[0071] According to Table 1 and the natural frequency formula of the flexible structure, it can be known that the length l of the free section 11 of the control harness body 10 is controlled to be ≤150mm, so that the vibration frequency of the harness body 10 avoids the excitation frequency of the engine, and the resonance of the harness body 10 is prevented, thereby reducing the vibration and noise response of the excitation frequency of the powertrain to the vehicle body 30, and effectively improving the comfort of the vehicle.

[0072] In some embodiments, Figure 1 and Figure 2 As shown, a first connector 12 and a second connector 13 are respectively provided at both ends of the length direction of the wiring harness body 10. The first connector 12 is connected to the power assembly, and the second connector 13 is connected to the power battery, thereby realizing the connection requirements between the wiring harness body 10 and the power assembly and the power battery.

[0073] According to some embodiments of the utility model, the dynamic stiffness of the fixing member 20 at least partially connected to the vehicle body 30 is greater than or equal to 5000N / mm, which can meet the fixing requirements of the fixing member 20 on the vehicle body 30, and can enhance the connection stability between the fixing member 20 and the vehicle body 30, and can reduce the vibration transmitted from the powertrain to the vehicle body 30 through the wiring harness body 10, and further improve the comfort of the vehicle. For example, in some specific embodiments, the dynamic stiffness of the fixing member 20 at least partially connected to the vehicle body 30 can be 5000N / mm, 5500N / mm, 6000N / mm, 6500N / mm, 7000N / mm, 7500N / mm, etc.

[0074] In some embodiments, after the wiring harness body 10 extends from the powertrain to the vehicle body 30, the first installation point on the vehicle body 30 for fixing the wiring harness body 10 will be subject to the greatest vibration excitation. Therefore, the dynamic stiffness of the fixing part 20 connected to this installation point is controlled to be greater than or equal to 5000N / mm, which can reduce the vibration transmitted from the powertrain to the vehicle body 30 through the wiring harness body 10 and improve the comfort of the vehicle.

[0075] Specifically, the dynamic stiffness K formula is derived as follows:

[0076]

[0077] ω=2πf

[0078] K=F(ω) / X(ω)

[0079] Where a is the acceleration of the response point as the frequency changes, in m / s 2 ; X(ω) is the displacement of the response point that changes with frequency, unit is m; F(ω) is the load of the excitation point that changes with frequency, unit is N; ω is the circular frequency, unit is rad / s; f is the natural frequency, unit is Hz; K is the stiffness of the response point that changes with frequency, unit is N / m.

[0080] Source point acceleration admittance function expression:

[0081]

[0082] According to the above formula, we can get the response curve IPI_k (logarithmic format), IPI f ——The corresponding vertical coordinate acceleration value on the curve obtained from IPI response analysis.

[0083] When frequency f = f i =i (i>0), the frequency f is obtained by i The dynamic stiffness is:

[0084]

[0085] According to the above formula, the dynamic stiffness curve K (logarithmic format) is obtained, and the ordinate is each frequency f i The corresponding dynamic stiffness value K fi .

[0086] The results are processed, that is, analyzed using the IPI response curve, and the equivalent dynamic stiffness Ka of the analysis point is compared with the dynamic stiffness target value Kd, so that the dynamic stiffness characteristics of the connection point with the vehicle body 30 can be analyzed. Therefore, it is concluded that the dynamic stiffness K of the fixing part 20 connected to the first mounting point on the vehicle body 30 for fixing the wiring harness body 10 is ≥ 5000N / mm, which can meet the required fixing requirements, effectively reduce the vibration and noise response of the excitation frequency of the powertrain to the vehicle body 30, and improve the comfort of the vehicle.
