Description

Technical Field

[0001] This application relates to the field of vehicle parts technology, and more particularly to a vibration damping tower assembly. Background Technology

[0002] Electric vehicles are increasingly becoming a popular mode of transportation due to their environmental friendliness and ease of handling. The vehicle frame structure is one of the key assemblies of an electric vehicle, serving as the carrier for the powertrain, chassis, and electrical equipment. In addition to meeting the requirements of its styling design, the vehicle frame structure must also satisfy requirements for layout, performance, manufacturing processes, and lightweighting.

[0003] A damper tower is a structure that integrates multiple sheet metal parts into a single unit. It bears the load and excitation from the chassis dampers and is a crucial component of the vehicle's frame. Damper towers are currently widely used in pure electric vehicles, range-extended electric vehicles, and hybrid vehicles. As electric vehicles mature, the requirements for vehicle weight are becoming increasingly stringent. Therefore, achieving lightweighting of the damper tower while meeting manufacturing and performance requirements is crucial for reducing overall vehicle weight. Based on this, it is necessary to explore a force transmission path for the damper tower that satisfies manufacturing, performance, and lightweighting requirements. This addresses the problem of cracking at connections caused by improper force transmission between the damper tower and surrounding components, leading to insufficient strength, NVH (Noise, Vibration, Harshness), and safety. Ultimately, this will effectively suppress torsional deformation of the vehicle body, reduce internal noise, and improve passenger comfort. Summary of the Invention

[0040] The technical solution of the present invention will be further described in detail below with reference to embodiments and accompanying drawings. The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0042] Please refer to Figure 1 and Figure 2 The left damping tower 2 and the right damping tower 3 are respectively and correspondingly installed at both ends of the upper crossbeam assembly 1 of the front windshield. The left vertical plate body 4 and the right vertical plate body 5 are respectively and correspondingly installed at both ends of the upper crossbeam assembly 1 of the front windshield. The left damping tower 2 is connected to the left vertical plate body 4, and the right damping tower 3 is connected to the right vertical plate body 5. The left damping tower 2 and the right damping tower 3 can be cast aluminum parts, which are lightweight and have good formability.

[0043] The heat pump crossbeam 6 is positioned opposite to the windshield upper crossbeam assembly 1 with a gap between them. The left vibration damping tower 2 and the right vibration damping tower 3 are respectively positioned at both ends of the heat pump crossbeam 6. The heat pump crossbeam 6 can also be made of cast aluminum to help reduce weight. Both ends are threaded to the left vibration damping tower 2 and the right vibration damping tower 3, respectively. The maximum vertical height of the heat pump crossbeam 6 can reach 35mm, and its high cross-section can better resist the load from the left vibration damping tower 2 and the right vibration damping tower 3.

[0044] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7The bolt hole 20a of the first crossbeam on the left tower of the left damping tower 2 is connected to the bolt hole 60 of the left crossbeam of the heat pump crossbeam 6 by bolts, and the bolt hole 30a of the first crossbeam on the right tower of the right damping tower 3 is connected to the bolt hole 61 of the right crossbeam of the heat pump crossbeam 6 by bolts; this heat pump crossbeam 6 can balance the load of the left damping tower 2 and the right damping tower 3, and can also effectively improve the torsional performance and NVH performance of the vehicle body.

[0045] The vibration damping tower assembly provided in this application embodiment, through the layout and connection of the front windshield upper beam assembly 1, left vibration damping tower 2, right vibration damping tower 3, left vertical plate body 4, right vertical plate body 5, and heat pump beam 6, enables the entire vibration damping tower assembly to form the following complete closed-loop force transmission path: left vibration damping tower 2 → left vertical plate body 4 → left end of front windshield upper beam assembly 1 → right end of front windshield upper beam assembly 1 → right vibration damping tower 3 → right vertical plate body 5 → right end of heat pump beam 6 → heat pump beam At the left end of 6, the aforementioned closed-loop structure provides a reasonable force transmission path for the vehicle body, avoiding cracking problems caused by unreasonable force transmission at the connection between the left damping tower 2, the right damping tower 3 and the front windshield upper crossbeam assembly 1, the left vertical plate body 4, and the right vertical plate body 5. This improves structural strength and increases safety, meeting the strength requirements of the left damping tower 2 and the right damping tower 3 while effectively suppressing torsional deformation of the vehicle body. This has a good effect on reducing the internal noise of the entire vehicle and improving the comfort of the occupants.

[0046] In an optional embodiment, the left vibration damping tower 2 is provided with a bent-connected first left tower overlapping surface 21 and a first side limiting platform 22, and the left vertical plate body 4 is provided with a bent-connected first left plate overlapping surface 40 and a second side limiting platform 41. The first left tower overlapping surface 21 is fitted onto the first left plate overlapping surface 40, and the first side limiting platform 22 and the second side limiting platform 41 abut against each other. Please refer to... Figures 1 to 2 The left vertical plate body 4 is installed on the upper part of the first left tower lap surface 21, and abuts against the left vibration damping tower 2 on the side through the second side limiting platform 41 abutting against the first side limiting platform 22, which increases the connection stability and force transmission reliability between the left vibration damping tower 2 and the left vertical plate body 4.

[0047] Please refer to Figure 10 The first left plate overlapping surface 40 of the left vertical plate body 4 sinks down to form a groove, and the first left tower overlapping surface 21 of the left vibration damping tower 2 is embedded in the groove, which helps to further increase the connection stability between the left vertical plate body 4 and the left vibration damping tower 2.

[0048] In addition, a left protruding rib 40a is provided on the bottom surface of the groove of the first left plate lap surface 40. The left protruding rib 40a can increase the structural strength of the first left plate lap surface 40 and improve the connection strength between the left vibration damping tower 2 and the left vertical plate body 4.

[0049] For the right vibration damping tower 3, the right tower lap surface 31 and the right protrusion rib 50a on the right vertical plate body 5's first right plate lap surface 50 are lapped by rivets and structural adhesive. The structural adhesive greatly improves the fatigue damage of the rivets.

[0050] Please refer to Figure 1 and Figure 2 The left vertical plate body 4 is also connected to the left end of the front windshield upper crossbeam assembly 1 via the second side limiting platform 41, such as... Figure 11 As shown, the right vertical plate body 5 is also connected to the right end of the front windshield upper crossbeam assembly 1 through the fourth side limiting platform 51 to increase the overall stability of the load.

The right vibration damping tower 3 is provided with a second right tower lap surface 33, and the right longitudinal beam 8 is provided with a right beam lap surface 80, the second right tower lap surface 33 being lapped and connected to the right beam lap surface 80. Please refer to... Figures 1 to 2 , Figures 12 to 13 The aforementioned overlapping structure can transfer the stress of the left vibration damping tower 2 and the right vibration damping tower 3 to the left longitudinal beam 7 and the right longitudinal beam 8, which helps to reduce the stress on the left vibration damping tower 2 and the right vibration damping tower 3 and reduce the probability of cracking of the left vibration damping tower 2 and the right vibration damping tower 3.

[0052] The second left tower lap surface 23 and the left beam lap surface 70 are connected at the connection point, and the second right tower lap surface 33 and the right beam lap surface 80 are connected at the connection point by rivets and structural adhesive.

[0053] Furthermore, the rivets in the above embodiments can be self-piercing rivets, which are stable and reliable.

[0054] In an optional embodiment, the upper windshield beam assembly 1 includes a first upper windshield beam 10 and a second upper windshield beam 11 that are fitted together; both ends of the upper windshield beam assembly 1 are respectively fitted together above the left damping tower 2 and the right damping tower 3. Please refer to... Figure 1 and Figure 2 The second front windshield upper crossbeam 11 is superimposed on the first front windshield upper crossbeam 10 and is fixed by bolts, welding or structural adhesive.

[0055] The two ends of the upper crossbeam assembly 1 of the front windshield are respectively installed above the left damping tower 2 and the right damping tower 3. Please refer to... Figure 8 and Figure 9Specifically, the left bolt hole 11a of the second upper crossbeam on the second front windshield upper crossbeam 11, the left bolt hole 10a of the first upper crossbeam on the first front windshield upper crossbeam 10, and the bolt hole 20b of the second crossbeam of the left tower of the left vibration damping tower 2 are aligned and then fastened together with bolts. The right bolt hole 11b of the second upper crossbeam on the second front windshield upper crossbeam 11, the right bolt hole 10b of the first upper crossbeam on the first front windshield upper crossbeam 10, and the bolt hole 30b of the second crossbeam of the right tower of the right vibration damping tower 3 are aligned and then fastened together with bolts. This achieves the effect of stably installing the left vibration damping tower 2 and the right vibration damping tower 3 on the left and right sides of the front windshield upper crossbeam assembly 1, which can transfer the load from the chassis to the left vibration damping tower 2 and the right vibration damping tower 3 to the front windshield upper crossbeam assembly 1, effectively avoiding the problem of cracking of the left vibration damping tower 2 and the right vibration damping tower 3 due to overload.

[0056] In an optional embodiment, the left vibration damping tower 2 is provided with a recessed left suspension mounting area 24, which has a left suspension connection hole 24a for connecting the left suspension. The right vibration damping tower 3 is provided with a recessed right suspension mounting area 34, which has a right suspension connection hole 34a for connecting the right suspension. Please refer to... Figure 3 and Figure 5 The left suspension mounting area 24 is recessed into a groove shape to facilitate the embedding of the left suspension. Bolts are used to fasten the left suspension to the left vibration damping tower 2 through the left suspension connection hole 24a. Similarly, the right suspension mounting area 34 is recessed into a groove shape to facilitate the embedding of the right suspension. Bolts are used to fasten the right suspension to the right vibration damping tower 3 through the right suspension connection hole 34a. Integrating the left suspension on the left vibration damping tower 2 and the right suspension on the right vibration damping tower 3 improves the overall integration of the vibration damping tower assembly and enhances the installation stability of both the left and right suspensions.

[0057] In an optional embodiment, the left suspension mounting area 24 has a left beam overlap through-hole 24b, and the left longitudinal beam 7 has a beam suspension mounting area 71. The left suspension mounting area 24 is directly opposite the left beam overlap through-hole 24b, so that the left suspension can be welded to the beam suspension mounting area 71 through the left beam overlap through-hole 24b. Please refer to... Figure 3 and Figure 12 Welding and fixing the left longitudinal beam 7 to the left suspension and the left vibration damping tower 2 will help to further increase the installation stability of the left suspension.

[0058] In an optional embodiment, the left vibration damping tower 2 has strip ribs 24c arranged around the left suspension connection hole 24a, and the right vibration damping tower 3 has radial ribs 34b arranged around the right suspension connection hole 34a. Figure 3As shown, multiple strip ribs 24c protrude from the surface of the left suspension mounting area 24 and are distributed circumferentially around the left suspension connection hole 24a. This helps to increase the structural strength near the left suspension connection hole 24a, allowing the area near the left suspension connection hole 24a to better bear and transmit the load of the left suspension. Figure 5 As shown, multiple radial ribs 34b are distributed circumferentially around the right suspension connection hole 34a, which helps to increase the structural strength near the right suspension connection hole 34a and enable the area near the right suspension connection hole 34a to better bear and transmit the load of the right suspension.

[0060] Optionally, the width of the extension rib 25b is greater than 2.5mm, preferably around 3mm, but is not limited to this thickness, as long as it is within the range allowed by the process.

The boss feature 28 can play a role in structural reinforcement of the left vibration damping tower 2. The boss feature 28 is higher than the left tower first crossbeam bolt hole 20a, the first left tower overlapping surface 21, the first side limiting platform 22 and other components on the left vibration damping tower 2. The greater the height of the boss feature 28, the better the modal value, which is more beneficial to NVH dynamic stiffness and strength.

[0062] In addition, the height of the annular radial rib 25a needs to be about 15mm higher than the boss feature 28; the right vibration damping tower 3 can be provided with a boss feature 28, annular radial rib 25a and extension rib 25b that are similar to those of the left vibration damping tower 2, which will not be described in detail here.

Please refer to... Figure 2 By replacing the solid structure at the bottom of the heat pump beam 6 with the crossbeam staggered ribs 62, the structural strength of the heat pump beam 6 can be guaranteed while reducing its weight.
