Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a battery high-voltage wiring harness fixing device and a vehicle. Background Technology

[0002] In hybrid electric vehicles (HEV / PHEV / REV, etc.), the high-voltage wiring harness between the power battery system and the powertrain is crucial. Because the power source of hybrid vehicles requires high-power, high-voltage electrical energy transmission, the battery high-voltage wiring harness typically has a large diameter and high rigidity. While existing wiring harness guard structures can constrain the wiring harness routing to some extent and prevent friction and interference with other vehicle components, powertrain vibrations can still be transmitted along the high-voltage wiring harness to the body or chassis, especially in the areas where the wiring harness guard is fixed. This vibration transmission often leads to secondary vibrations in the body structure. This not only increases vehicle noise but can also cause NVH problems such as pedal vibration, steering wheel instability, or humming sounds inside the vehicle, affecting the driving experience and vehicle performance.

[0003] Therefore, how to effectively control the transmission of powertrain vibration through the wiring harness to improve the vehicle's NVH performance without significantly increasing weight and cost has become one of the important technical issues in the relevant technical field. At present, no effective solution has been proposed to address the above issues. Summary of the Invention

[0004] This application provides a battery high-voltage wiring harness fixing device and a vehicle, which aims to improve the vibration and noise problem caused by the vibration transmission of the powertrain in related technologies.

[0005] According to one aspect of the embodiments of this application, a battery high-voltage wiring harness fixing device is provided. The battery high-voltage wiring harness fixing device includes: a fixing component having a receiving space for accommodating a target wiring harness, the fixing component having a fixing leg located on one side of the receiving space, and a mounting structure provided on the fixing leg; a vibration damping pad located at the mounting structure, the vibration damping pad cooperating with a locking member, and the fixing leg being connected to the vehicle body crossbeam through the vibration damping pad.

[0006] The battery high-voltage wiring harness fixing device provided in this application embodiment achieves the following technical effects: the accommodating space ensures that the high-voltage wiring harness is not squeezed during the fixing process, maintaining the integrity and electrical performance of the wiring harness. The mounting structure on the fixing feet, in conjunction with the vibration damping pad, forms an effective vibration isolation system. The vibration damping pad is connected to the vehicle body crossbeam through locking components. This connection method not only ensures the stability of the fixing components but also reduces the direct transmission of vibration energy to the vehicle body crossbeam, avoiding vibration problems or interior noise issues caused by the wiring harness in components such as the side pedals and steering wheel. Through this design, the entire high-voltage wiring harness fixing device maintains the stability of the wiring while improving the overall vibration isolation effect of the system, thereby protecting the wiring harness from damage caused by powertrain vibration and extending the service life of the wiring harness.

[0007] Furthermore, the vibration isolation pad is snapped into place with the fixed support leg.

[0008] The above-described optional embodiments of this application achieve the following beneficial effects: the snap-fit ​​design simplifies the assembly process, improves assembly efficiency, and reduces production costs. Simultaneously, the snap-fit ​​ensures the stable position of the vibration damping pad on the fixed support, preventing displacement of the vibration damping pad during vehicle operation, thereby maintaining consistent vibration damping performance. This design also ensures that the vibration damping pad can effectively absorb and disperse vibration when the high-voltage wiring harness transmits vibration energy, reducing the vibration amplitude of the fixed components and improving the durability of the protective plate.

[0009] Furthermore, at least part of the vibration isolation pads are located inside the mounting structure, while another part of the vibration isolation pads are located outside the mounting structure, with the portion of the vibration isolation pads located outside the mounting structure abutting against the vehicle body crossbeam.

[0010] The above-described optional embodiments of this application achieve the following beneficial effects: By placing the vibration damping pad portion within the mounting structure, the installation position of the vibration damping pad can be precisely controlled, ensuring maximum vibration damping effect. The direct contact between the vibration damping pad and the vehicle body crossbeam reduces the vibration amplitude at the fixing point, minimizing wiring harness swaying and friction with surrounding components caused by vibration. This design significantly improves the stability and vibration damping effect of the protective plate structure without increasing weight or cost.

[0011] Furthermore, the mounting structure is configured as a first through hole, with at least a portion of the vibration isolation pad located within the first through hole. The vibration isolation pad has a circumferential groove, which engages with the fixed support foot.

[0012] The above-described optional embodiments of this application achieve the following beneficial effects: the design of the first through hole allows the locking element to pass through, enabling the connection between the vibration damping pad and the vehicle body crossbeam. Simultaneously, the engagement between the groove and the fixed support ensures the vibration damping pad is fixed in position on the fixed assembly, enhancing the stability of the vibration damping pad. The combination of the groove and the engagement allows the vibration damping pad to be more firmly fixed in position when bearing the vibration energy transmitted by the wiring harness, preventing deformation and displacement of the vibration damping pad during vibration, thereby improving the reliability and stability of the vibration damping effect.

[0013] Furthermore, a second through hole is provided along the axial direction of the vibration isolation pad, through which the locking component can pass and be connected to the vehicle body crossbeam.

[0014] The above-described optional embodiments of this application achieve the following beneficial effects: The second through hole allows the locking member to pass through the vibration damping pad and connect directly to the vehicle body crossbeam. This design ensures the axial fixation of the vibration damping pad and enhances the vibration damping effect. The direct connection between the locking member and the vehicle body crossbeam reduces the relative movement between the vibration damping pad and the vehicle body crossbeam, reduces additional vibration and noise caused by relative movement, and further improves the vehicle's NVH performance.

[0015] Furthermore, there are multiple fixed feet and multiple vibration isolation pads, with each fixed foot and vibration isolation pad corresponding to the other.

[0016] The above-described optional embodiments of this application achieve the following beneficial effects: the arrangement of multiple fixed feet and vibration damping pads creates a multi-point support and vibration damping effect, which can more evenly distribute the vibration energy transmitted by the wiring harness, reduce stress concentration at individual fixed points, and improve the stability and reliability of the entire system. The one-to-one correspondence arrangement ensures that each vibration damping pad can function in its optimal position, reducing the swaying and displacement of the wiring harness when transmitting vibration energy, reducing friction and interference between the wiring harness and other parts of the vehicle body, and simultaneously improving the service life and safety performance of the wiring harness.

[0017] Furthermore, the fixing assembly includes: a fixing plate body, which is arranged along the length direction of the target wire harness, has a receiving space, and is fixed to the target wire harness by cable ties. One end of each fixing leg is connected to the fixing plate body, and the other end of each fixing leg is connected to the vehicle body crossbeam through each vibration isolation pad.

[0018] The above-described optional embodiments of this application achieve the following beneficial effects: The fixing plate body provides a stable base platform for the entire high-voltage wiring harness. By fixing the harness with cable ties, the stability and positioning accuracy of the harness along its entire length are ensured, preventing excessive shaking and displacement of the harness. The fixing feet connected to the fixing plate body are connected to the vehicle body crossbeams through vibration damping pads. This design not only improves the fixing stability of the wiring harness but also reduces the impact of harness vibration on the vehicle body, lowering interior noise and vibration.

[0019] Furthermore, the multiple vibration isolation pads include a first vibration isolation pad, a second vibration isolation pad, and a third vibration isolation pad. The first vibration isolation pad is located on one side of the fixed plate body, and the second and third vibration isolation pads are located on the other side of the fixed plate body. The lines connecting the first and second vibration isolation pads, the lines connecting the first and third vibration isolation pads, and the lines connecting the second and third vibration isolation pads form a triangular structure.

[0020] The above-described optional embodiments of this application achieve the following beneficial effects: The triangular structure possesses extremely high stability and rigidity, effectively dispersing and absorbing the vibration energy transmitted by the high-voltage wiring harness, thus preventing excessive deformation and damage to a single vibration isolation pad when subjected to significant vibration. The arrangement of the first, second, and third vibration isolation pads, forming a triangular structure through their connecting lines, allows for a more uniform distribution of vibration energy, reduces stress concentration in the fixed components, and improves the vibration isolation effect and durability of the entire system. The triangular vibration isolation pad design also avoids resonance at the wiring harness fixing points, reducing the efficiency of powertrain vibration transmission to the vehicle body, and improving driving comfort and vehicle safety.

[0021] Furthermore, the distance between the first vibration isolation pad and the second vibration isolation pad is h1, the distance between the first vibration isolation pad and the third vibration isolation pad is h2, and the distance between the second vibration isolation pad and the third vibration isolation pad is h3, wherein 111.5mm≤h1≤112.5mm, and / or 130.5mm≤h2≤131.5mm, and / or 98.5mm≤h3≤99.5mm.

[0022] The above-described optional embodiments of this application can achieve the following beneficial effects: precise control of the distance between vibration isolation pads can optimize the distribution of vibration energy, avoid resonance phenomena that may occur at specific distances, and improve the consistency and reliability of vibration isolation effect. By adjusting the distance between vibration isolation pads, the rigid body mode of the entire fixing device can be further optimized, the natural frequency of the wiring harness guard plate can be increased, the probability of coupling with the powertrain vibration frequency can be reduced, and the vehicle body vibration and noise problems caused by resonance can be reduced.

[0023] According to another aspect of the present invention, a vehicle is provided, including a battery high-voltage wiring harness fixing device, wherein the battery high-voltage wiring harness fixing device is the battery high-voltage wiring harness fixing device of the above embodiment.

[0024] The above-mentioned optional embodiments of this application can achieve the following beneficial effects: integrating the above-mentioned optimized battery high-voltage harness fixing device into the vehicle can directly improve the vehicle's NVH performance, reduce body vibration and noise caused by the high-voltage harness, improve driving experience and vehicle safety. The optimized fixing device design not only reduces vehicle vibration and noise during driving, but also maintains the vehicle's lightweight characteristics, reduces vehicle energy consumption and maintenance costs, and improves the overall performance of the vehicle.

[0037] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0038] Combination Figures 1 to 2 As shown, according to a specific embodiment of the present invention, a battery high-voltage wiring harness fixing device is provided.

[0039] Specifically, such as Figure 1 As shown, the battery high-voltage wiring harness fixing device includes: a fixing component 10, which has a receiving space 121 for accommodating the target wiring harness 100, a fixing leg 11 located on one side of the receiving space 121, and a mounting structure 111 on the fixing leg 11; a vibration damping pad 20, which is located at the mounting structure 111, and cooperates with the locking member 30. The fixing leg 11 is connected to the vehicle body crossbeam 200 through the vibration damping pad 20.

[0040] In this embodiment, by setting the fixing component 10 to have a receiving space 121 for accommodating the target wiring harness 100, the target wiring harness 100 can be effectively fixed in a predetermined position. By setting the mounting structure on the fixing foot 11 in combination with the vibration damping pad 20 and the locking member 30, the shaking and displacement of the target wiring harness 100 during vehicle operation is prevented. The vibration damping pad 20 is located at the mounting structure of the fixing foot 11 and works in conjunction with the locking member 30. Through the vibration damping characteristics of the vibration damping pad 20, the transmission of wiring harness vibration to the vehicle body beam is effectively isolated, the secondary vibration of the vehicle body structure is reduced, and the NVH problems caused by wiring harness vibration, such as pedal vibration and in-vehicle noise, are solved, significantly improving the driver's comfort experience.

[0041] In other embodiments, the angle and position of the fixed support 11 are adjustable to accommodate fine-tuning of the wiring harness layout, ensuring optimal fixed position and orientation of the wiring harness.

[0042] Furthermore, the vibration isolation pad 20 is snapped into the fixed support 11. The snap-fit ​​design simplifies the assembly of the vibration isolation pad 20 and the fixed support 11, improves production efficiency, and ensures the stability of the vibration isolation pad when subjected to powertrain vibration, preventing it from easily shifting or failing.

[0043] In other embodiments, the vibration isolation pad 20 and the fixed support leg 11 can also be configured as an integral molding.

[0044] Combination Figure 2 As shown, at least a portion of the vibration isolation pads 20 are located inside the mounting structure 111, while another portion of the vibration isolation pads 20 are located outside the mounting structure 111. The portion of the vibration isolation pads 20 located outside the mounting structure abuts against the vehicle body crossbeam 200.

[0045] The above-mentioned arrangement increases the effective contact area between the vibration isolation pad 20 and the vehicle body crossbeam 200, thereby improving the vibration isolation performance of the vibration isolation pad 20. The portion of the vibration isolation pad 20 located outside the mounting structure can directly absorb the vibration energy from the target wiring harness 100, while the portion of the vibration isolation pad 20 located inside the structure can prevent excessive deformation of the vibration isolation pad 20 at the fixed point, ensuring the durability and vibration isolation consistency of the vibration isolation pad 20.

[0046] In one embodiment, the mounting structure 111 is configured as a first through hole, at least a portion of the vibration isolation pad 20 is located in the first through hole, and the vibration isolation pad 20 is provided with a groove in the circumference, the groove engaging with the fixed support leg 11.

[0047] Through the aforementioned structure, the first through hole allows the locking member 30 to connect more directly to the vehicle body crossbeam 200, ensuring the stability of the fixing assembly. The groove of the vibration damping pad 20 engages with the fixing foot 11, further enhancing the positioning stability and vibration damping efficiency of the vibration damping pad. This structure can more effectively disperse the vibration energy transmitted by the high-voltage target wiring harness 100, prevent local stress concentration, thereby avoiding damage to the fixing assembly and extending its service life.

[0048] In another embodiment, the mounting structure 111 can also be configured as a groove structure, and the vibration isolation pad 20 is provided with a protruding structure in the circumferential direction. The protruding structure of the vibration isolation pad 20 cooperates with the groove structure to realize the snap-fit ​​between the vibration isolation pad 20 and the fixed support 11.

[0049] Furthermore, a second through hole 24 is provided along the axial direction of the vibration isolation pad 20, and the locking member 30 can pass through the second through hole 24 and be connected to the vehicle body crossbeam 200.

[0050] Through the aforementioned structure, the second through hole 24 allows the locking member 30 to pass through the vibration damping pad 20 and connect to the vehicle body crossbeam 200. This design not only ensures a stable connection of the vibration damping pad 20 but also improves the vibration damping effect. By directly connecting the locking member 30 to the vehicle body crossbeam 200, the relative displacement between the vibration damping pad 20 and the vehicle body crossbeam 200 is reduced, thereby reducing additional vibration and noise caused by displacement and further enhancing the vehicle's NVH performance.

[0051] Furthermore, there are multiple fixed feet 11 and multiple vibration isolation pads 20, with each fixed foot 11 corresponding to a vibration isolation pad 20.

[0052] With the above structure, multiple fixed supports 11 are correspondingly arranged with multiple vibration isolation pads 20, enabling the fixing assembly to simultaneously fix the target wire harness 100 at multiple points, thereby improving the stability of the target wire harness 100. This multi-point fixing method disperses the force of vibration transmitted by the target wire harness 100, reduces stress concentration at a single fixing point, improves the durability of the vibration isolation pads 20, and at the same time reduces the swaying of the target wire harness 100 and reduces the risk of interference with surrounding components.

[0053] Furthermore, the fixing assembly 10 includes: a fixing plate body 12, which is arranged along the length direction of the target wire harness 100, the fixing plate body 12 has a receiving space 121, the fixing plate body 12 is fixed to the target wire harness 100 by cable ties, one end of each fixing leg 11 is connected to the fixing plate body 12, and the other end of each fixing leg 11 is connected to the vehicle body crossbeam 200 through each vibration isolation pad 20.

[0054] Specifically, the fixing plate body 12 has a semi-enclosed structure with an opening on one side.

[0055] Through the aforementioned structure, the fixing plate body 12 provides full support and protection for the target wiring harness 100. By securing the target wiring harness 100 to the fixing plate body with cable ties, the target wiring harness 100 not only achieves good positioning but also avoids unnecessary displacement during vehicle operation. The connection between the fixing feet 11 and the fixing plate body 12, as well as the vibration-damping connection with the vehicle body crossbeam 200, ensures a stable connection between the target wiring harness 100 guard plate and the vehicle body crossbeam, reducing the impact of powertrain vibration on the vehicle body and improving driving comfort.

[0056] Preferably, the plurality of vibration isolation pads 20 include a first vibration isolation pad 21, a second vibration isolation pad 22, and a third vibration isolation pad 23. The first vibration isolation pad 21 is located on one side of the fixed plate body 12, and the second vibration isolation pad 22 and the third vibration isolation pad 23 are located on the other side of the fixed plate body 12. The lines connecting the first vibration isolation pad 21 and the second vibration isolation pad 22, the lines connecting the first vibration isolation pad 21 and the third vibration isolation pad 23, and the lines connecting the second vibration isolation pad 22 and the third vibration isolation pad 23 form a triangular structure.

[0057] Through the above structure, the first vibration isolation pad 21, the second vibration isolation pad 22, and the third vibration isolation pad 23 form a highly stable triangular structure, which can effectively disperse the vibration energy transmitted by the high-voltage wire harness, avoid excessive stress on a single vibration isolation pad, and reduce the resonance risk of the fixing component. The triangular vibration isolation pad 20 not only improves the vibration isolation effect but also increases the rigidity of the entire fixing device, further improving the stability of the wire harness.

[0058] In other embodiments, the number of vibration isolation pads 20 is not limited to this, and can also be set to five, six, etc.

[0059] Furthermore, the distance between the first vibration isolation pad 21 and the second vibration isolation pad 22 is h1, the distance between the first vibration isolation pad 21 and the third vibration isolation pad 23 is h2, and the distance between the second vibration isolation pad 22 and the third vibration isolation pad 23 is h3, wherein 111.5mm≤h1≤112.5mm, and / or 130.5mm≤h2≤131.5mm, and / or 98.5mm≤h3≤99.5mm.

[0060] By precisely controlling the distance between the three vibration isolation pads 20 through the above settings, the distribution of vibration energy can be optimized, and resonance can be avoided at a specific distance.

[0061] In one embodiment, h1 = 112 mm, and / or h2 = 131 mm, and / or h3 = 99 mm.

[0062] According to another aspect of the present invention, a vehicle is provided, including a battery high-voltage wiring harness fixing device, which is the battery high-voltage wiring harness fixing device of the above embodiment. The battery high-voltage wiring harness fixing device includes: a fixing component 10, the fixing component 10 having a receiving space 121 for accommodating a target wiring harness 100, the fixing component 10 having a fixing leg 11 located on one side of the receiving space 121, and the fixing leg 11 having a mounting structure 111; a vibration damping pad 20, the vibration damping pad 20 being located at the mounting structure 111, the vibration damping pad 20 cooperating with a locking member 30, and the fixing leg 11 being connected to the vehicle body crossbeam 200 through the vibration damping pad 20.

[0063] Integrating the battery high-voltage wiring harness fixing device of any of the above embodiments into the vehicle can directly improve the vehicle's NVH performance, reduce vibration and noise caused by the wiring harness, and enhance the driving experience and overall vehicle safety. The optimized fixing device design not only reduces vibration and noise during vehicle operation but also maintains the vehicle's lightweight design, lowers energy consumption and maintenance costs, and improves overall vehicle performance.
