Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a vibration damping tower. Background Technology

[0002] Among the many structures of a vehicle, the shock absorber tower in the engine compartment is a very important component. The shock absorber tower houses important chassis components such as shock absorbers and upper wishbones. Only when the mounting points of these chassis components on the shock absorber tower have very high rigidity can they provide good support for the chassis components and allow them to perform well. The higher the rigidity of the mounting points, the less deformation occurs at the mounting points during vehicle use, and the fewer abnormal noises caused by deformation of the shock absorber tower and chassis components.

[0003] Since the damper tower is directly subjected to various loads transmitted from the road surface through the front suspension, it also needs to have good strength to meet the various operating conditions of the vehicle and avoid durability problems. Furthermore, since the various loads transmitted from the road surface through the front suspension are then transmitted to the passenger compartment through the damper tower, affecting the NVH (Noise, Vibration, and Harshness) performance of the vehicle, the damper tower also needs to have sufficient dynamic stiffness to filter the loads transmitted from the front suspension and improve the NVH performance of the vehicle. Utility Model Content

[0004] In view of the above, it is necessary to propose a vibration damping tower to improve its stiffness and NVH performance.

[0005] This application provides a vibration damping tower, including: a mounting part for mounting vibration dampers; an outer sidewall surrounding one side of the mounting part and forming an accommodating space with the mounting part; and an inner reinforcing wall disposed within the accommodating space and surrounding the outer sidewall, wherein the inner reinforcing wall and the outer sidewall form an mounting space for an upper fork arm.

[0006] In some embodiments, one end of the internal reinforcing wall is connected to the external sidewall and forms a wedge-shaped structure, and the other end of the internal reinforcing wall extends away from the mounting portion and forms the mounting space of the upper fork arm between it and the external sidewall.

[0007] In some embodiments, the vibration damping tower further includes a plurality of pin bosses, which are spaced apart on the inner reinforcing wall and / or the outer sidewall to form a frame supporting the inner reinforcing wall and / or the outer sidewall. One end of each pin boss is connected to the mounting portion, and the other end of each pin boss extends away from the mounting portion and protrudes from the inner reinforcing wall or the outer sidewall.

[0008] In some embodiments, the vibration damping tower further includes a first reinforcing rib, which is disposed between the outer sidewall and the inner reinforcing wall, and the two ends of the first reinforcing rib are respectively connected to the outer sidewall and the inner reinforcing wall.

[0010] In some embodiments, the outer sidewall has a slot and a storage hole communicating with the slot. The detachable connecting plate includes a plate body and a nut disposed on one side of the plate body. The plate body is inserted into the slot, and the nut is disposed in the storage hole. The connector can pass through the nut and connect to the upper fork arm in the installation space.

[0011] In some embodiments, the outer sidewall includes a front outer wall and a rear outer wall, both of which are connected to the mounting portion. The front outer wall and / or the rear outer wall each include a plurality of connected sidewalls, wherein the included angle between any two adjacent sidewalls is an obtuse angle to form a sloped structure.

[0012] In some embodiments, the outer sidewall further includes a right outer wall disposed between the front outer wall and the rear outer wall, one side of the right outer wall being connected to the mounting portion, and an induction notch being provided on the side of the right outer wall away from the mounting portion.

The outer side wall and the internal reinforcing wall can form an inner and outer double wall structure, which can form two relatively complete load transmission paths in the direction perpendicular to the installation part, thereby improving the stiffness and NVH performance of the vibration damping tower.

Detailed Implementation

[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0030] Because the shock absorber tower is located in a critical position in the vehicle's engine compartment, it is required that the shock absorber tower can be crushed or broken in time after being subjected to a severe impact during a high-speed collision, so as to avoid the shock absorber tower squeezing the passenger compartment and causing injury to the occupants.

[0031] In conventional automotive structural design, the front shock absorber towers using MacPherson strut suspensions typically employ a sheet metal welded structure. While this structure is simple and widely used, it suffers from poor NVH performance and is primarily found in low- to mid-range models. In contrast, the shock absorber towers using double wishbone suspensions have a more complex sheet metal welded structure. Furthermore, to meet the chassis mounting point stiffness and NVH performance requirements of the vehicle's positioning, the structure of the front shock absorber tower undergoes significant reinforcement, resulting in a substantial increase in its weight. For new energy vehicles, this directly impacts the vehicle's range performance.

[0032] Therefore, this application provides a vibration damping tower, which achieves a balance of multiple attributes such as weight, chassis mounting point stiffness, strength, NVH performance, and safety performance by using a cast aluminum structure instead of a sheet metal welded structure.

[0033] Specifically, please refer to Figure 1 and Figure 2 The vibration damping tower 1 includes an installation part 10, an outer side wall 20, and an inner reinforcing wall 30.

[0034] Mounting section 10 is used to mount the vibration damper. The outer sidewall 20 includes a front outer wall 21, a left outer wall 22, a rear outer wall 23, and a right outer wall 24 connected sequentially end-to-end. The front outer wall 21, left outer wall 22, rear outer wall 23, and right outer wall 24 are all located on one side of the mounting section 10 and form an accommodating space 25 with the mounting section 10. An inner reinforcing wall 30 is located within the accommodating space 25 and surrounds the outer sidewall 20. The inner reinforcing wall 30 includes a front inner wall 31, a left inner wall 32, and a rear inner wall 33 connected sequentially. The front inner wall 31 corresponds to the front outer wall 21. Please refer to [reference needed]. Figure 3 One end of the front inner wall 31 is connected to the front outer wall 21 to form a first wedge structure 34, and the other end of the front inner wall 31 forms a first installation space 35 between the front outer wall 21 and the front inner wall 31. The rear inner wall 33 is correspondingly arranged with the rear outer wall 23. One end of the rear inner wall 33 is connected to the rear outer wall 23 to form a second wedge structure 36, and the other end of the rear inner wall 33 forms a second installation space 37 between the rear outer wall 23 and the rear inner wall 33. The first installation space 35 and the second installation space 37 are used to install the two arms of the upper fork arm. The left inner wall 32 is correspondingly arranged with the left outer wall 22. The end of the front inner wall 31 away from the left inner wall 32 and the end of the rear inner wall 33 away from the left inner wall 32 are arranged opposite to each other and are respectively connected to the inner wall surface of the right outer wall 24.

[0035] In some embodiments, see Figure 4 The vibration damping tower 1 also includes multiple first ejector pin bosses 40, multiple second ejector pin bosses 50, and multiple first reinforcing ribs 60. The multiple first ejector pin bosses 40 are respectively spaced on the inner reinforcing wall 30 to form an inner wall skeleton 41. One end of each first ejector pin boss 40 is connected to the mounting part 10, and the other end of each first ejector pin boss 40 extends away from the mounting part 10 and out of the inner reinforcing wall 30. The multiple second ejector pin bosses 50 are respectively spaced on the outer side wall 20 to form an outer wall skeleton 51. One end of each second ejector pin boss 50 is connected to the mounting part 10, and the other end of each second ejector pin boss 50 extends away from the mounting part 10 and out of the outer side wall 20. The multiple first reinforcing ribs 60 are spaced between the outer side wall 20 and the inner reinforcing wall 30 to increase the strength of the outer side wall 20 and the inner reinforcing wall 30.

[0036] It is understood that in other embodiments, the vibration damping tower 1 only includes a first pin boss 40 provided on the internal reinforcing wall 30.

[0037] It is understood that in other embodiments, the vibration damping tower 1 only includes a second pin boss 50 provided on the outer sidewall 20.

[0038] Specifically, among the plurality of first ejector protrusions 40, the first ejector protrusions 40 can be disposed on the front inner wall 31, the left inner wall 32, and the rear inner wall 33, and the plurality of second ejector protrusions 50 can be disposed on the front outer wall 21, the rear outer wall 23, and the right outer wall 24. The first reinforcing rib 60 is disposed between the front inner wall 31 and the front outer wall 21, and between the rear inner wall 33 and the rear outer wall 23. One end of the first reinforcing rib 60 can be connected to the front inner wall 31, the first ejector protrusion 40 located on the front inner wall 31, the rear inner wall 33, or the first ejector protrusion 40 located on the rear inner wall 33, and the other end of the first reinforcing rib 60 can be connected to the front outer wall 21, the second ejector protrusion 50 located on the front outer wall 21, the rear outer wall 23, or the second ejector protrusion 50 located on the rear outer wall 23.

[0039] In existing designs, ejector pin bosses are merely protrusions at the ends of the internal reinforcing wall 30 and the external sidewall 20 for easy demolding. However, the multiple first ejector pin bosses 40 and multiple second ejector pin bosses 50 provided in this application not only facilitate demolding but also form the inner wall skeleton 41 and outer wall skeleton 51, increasing the strength of the internal reinforcing wall 30 and the external sidewall 20, thereby improving their rigidity. Specifically, both the first ejector pin bosses 40 and the second ejector pin bosses 50 are columnar structures.

[0040] By setting multiple first reinforcing ribs 60, the inner reinforcing wall 30 and the outer sidewall 20 can support and reinforce each other, further improving the rigidity and strength of the inner reinforcing wall 30 and the outer sidewall 20. Thus, under the combined action of the first ejector boss 40, the second ejector boss 50, and the first reinforcing ribs 60, the rigidity and strength of the inner reinforcing wall 30 can be improved, thereby facilitating the thinning of the inner reinforcing wall 30.

[0041] In some embodiments, in two of the plurality of first ejector protrusions 40, each first ejector protrusion 40 is disposed at the connection between the front outer wall 21 and the right outer wall 24; in two of the plurality of second ejector protrusions 50, at least one second ejector protrusion 50 is disposed at the connection between the front inner wall 31 and the right outer wall 24; in two of the plurality of first reinforcing ribs 60, each first reinforcing rib 60 has its two ends connected to the front outer wall 21 and the front inner wall 31 respectively and is spaced apart from the right outer wall 24; wherein, the first mounting space 35 and the second mounting space 37 are both formed by the corresponding front outer wall 21, front inner wall 31, first reinforcing rib 60 and right outer wall 24.

[0042] By connecting both ends of the first reinforcing rib 60 to the front outer wall 21 and the front inner wall 31 respectively, and creating a gap between it and the right outer wall 24, the first mounting space 35 and the second mounting space 37 can be made into a semi-enclosed structure. This allows the first mounting space 35 and the second mounting space 37 to form an integral load-bearing structure, improving the rigidity and strength of the two arms of the upper fork arm. Furthermore, by providing a first ejector boss 40 at the connection between the front outer wall 21 and the right outer wall 24, and a second ejector boss 50 at the connection between the front inner wall 31 and the right outer wall 24, the connection rigidity between the front outer wall 21 and the right outer wall 24, as well as the connection rigidity between the front inner wall 31 and the right outer wall 24, is improved, thereby further enhancing the rigidity and strength of the two arms of the upper fork arm.

[0043] In some embodiments, see Figure 1 and Figure 5 The vibration damping tower 1 also includes two detachable connecting plates 70. These two detachable connecting plates 70 are detachably disposed on the side of the front outer wall 21 facing away from the inner reinforcing wall 30 and the side of the rear outer wall 23 facing away from the inner reinforcing wall 30, respectively, and are respectively disposed corresponding to the first mounting space 35 and the second mounting space 37, so as to connect the two arms of the upper fork arm in the first mounting space 35 and the second mounting space 37 respectively via connectors (not shown). By using detachable connecting plates 70 to connect the two arms of the upper fork arm, replacement is convenient and cost-effective when the detachable connecting plates 70 are damaged during use.

[0044] In some embodiments, see Figure 5 and Figure 6The detachable connecting plate 70 includes a plate body 71 and a nut 72 located on one side of the plate body 71. The plate body 71 has a square structure with four straight sides. It can be cold-forged as a single piece or stamped sheet metal with projection welding of the nut 72. The front outer wall 21 and the rear outer wall 23 are provided with protrusions 211 at the corresponding positions of the detachable connecting plate 70. The end of the protrusion 211 near the mounting part 10 is provided with a slot 211A and a storage hole 211B communicating with the slot 211A. The plate body 71 is inserted into the slot 211A, and the nut 72 is located in the storage hole 211B. The connector can pass through the nut 72 and connect to the upper fork arm in the first mounting space 35 and the second mounting space 37.

[0045] Specifically, the connector is a bolt. The protrusion 211 consists of two flanges 211C on both sides and a retaining wall 211D connected to the two flanges 211C. The receiving hole 211B is opened at one end of the retaining wall 211D. The retaining wall 211D of the slot 211A is used to limit the movement of the plate 71 during the tightening of the connector, preventing the plate 71 from rotating and making it impossible to tighten the bolt. The flanges 211C of the slot 211A are used to prevent the plate 71 from sliding out of the slot 211A when assembling the plate 71, thereby improving assembly efficiency.

[0046] It is understandable that the plate 71 can also adopt a polygonal structure, as long as it is ensured that the two sides of the polygon and the retaining wall 211D of the slot 211A accurately generate the limit.

[0047] In some embodiments, see Figure 7 The front outer wall 21 includes a first front side wall 212, a second front side wall 213, and a third front side wall 214 connected in sequence. The included angles between the first front side wall 212 and the second front side wall 213, and between the second front side wall 213 and the third front side wall 214 are all obtuse angles to form a slope structure. The end of the first front side wall 212 away from the second front side wall 213 is connected to the mounting part 10. The left outer wall 22 is connected to the same side of the first front side wall 212, the second front side wall 213, and the third front side wall 214. The right outer wall 24 is connected to the other side of the first front side wall 212, the second front side wall 213, and the third front side wall 214.

[0048] The second front sidewall 213 connects the first front sidewall 212 and the third front sidewall 214 through a large-angle inclined structure to eliminate the structural step problem caused by the surface difference between the first front sidewall 212 and the third front sidewall 214 in the X-axis direction. This makes the structural transition smoother and can effectively reduce the stress concentration problem on the front outer wall 21. Furthermore, the first front sidewall 212, the second front sidewall 213, and the third front sidewall 214 are close to a whole inclined surface. Compared with the segmented sidewall of the traditional stepped structure, this whole inclined sidewall not only makes the stiffness performance of the front outer wall 21 itself better, but also improves the stiffness of the vibration damping tower 1 in the Z-axis direction.

[0049] In some embodiments, see Figure 8 The rear outer wall 23 includes a first rear side wall 231, a second rear side wall 232, and a third rear side wall 233. The included angles between the first rear side wall 231 and the second rear side wall 232, and between the second rear side wall 232 and the third rear side wall 233 are all obtuse angles to form a slope structure. The end of the first rear side wall 231 away from the second rear side wall 232 is connected to the mounting part 10. The left outer wall 22 is connected to the same side of the first rear side wall 231, the second rear side wall 232, and the third rear side wall 233. The right outer wall 24 is connected to the other side of the first rear side wall 231, the second rear side wall 232, and the third rear side wall 233.

[0050] The second rear sidewall 232 connects the first rear sidewall 231 and the third rear sidewall 233 through a large-angle inclined structure to eliminate the structural step problem caused by the surface difference between the first rear sidewall 231 and the third rear sidewall 233 in the X-axis direction. This makes the structural transition smoother and can effectively reduce the stress concentration problem on the rear outer wall 23. Furthermore, the first rear sidewall 231, the second rear sidewall 232, and the third rear sidewall 233 are close to a whole inclined surface. Compared with the segmented sidewall of the traditional stepped structure, this whole inclined sidewall not only makes the stiffness performance of the rear outer wall 23 itself better, but also improves the stiffness of the vibration damping tower 1 in the Z-axis direction.

[0051] It is understood that in other embodiments, only the included angle between the first front sidewall 212 and the second front sidewall 213, and the included angle between the second front sidewall 213 and the third front sidewall 214 are obtuse angles to form a sloped structure.

[0052] It is understood that in other embodiments, only the included angle between the first rear sidewall 231 and the second rear sidewall 232, and the included angle between the second rear sidewall 232 and the third rear sidewall 233 are obtuse angles to form a sloped structure.

[0053] In some embodiments, see Figure 9The right outer wall 24 includes a first right side wall 241, a second right side wall 242, and a third right side wall 243. The first right side wall 241 and the third right side wall 243 are spaced apart on one side of the second right side wall 242, and an induction notch 244 is formed between the first right side wall 241 and the third right side wall 243. A stepped structure 245 is formed between the second right side wall 242 and the third right side wall 243. The stepped structure 245 is located at the induction notch 244 and between the mounting part 10 and the induction notch 244. The side of the second right side wall 242 away from the first right side wall 241 is connected to the mounting part 10. The front outer wall 21 is connected to the same side of the first right side wall 241 and the second right side wall 242. The rear outer wall 23 is connected to the same side of the second right side wall 242 and the third right side wall 243.

[0054] By forming an induced notch 244 between the first right side wall 241 and the third right side wall 243, the local structure of the right outer wall 24 can be weakened, resulting in a sudden change in stiffness. Furthermore, by forming a stepped structure 245 between the second right side wall 242 and the third right side wall 243, the right outer wall 24 can fold in the area of ​​the stepped structure 245 during a high-speed collision. Through these modifications, the damper tower 1 can be crushed or broken during a high-speed collision, preventing it from compressing the passenger compartment and thus improving the safety of the occupants.

[0055] In some embodiments, see Figure 10 and Figure 11 The left outer wall 22 includes a first left side wall 221, a second left side wall 222, and a third left side wall 223 connected in sequence. The included angles between the first left side wall 221 and the second left side wall 222, and between the second left side wall 222 and the third left side wall 223, are all obtuse angles to form a beveled structure. The end of the first left side wall 221 away from the second left side wall 222 is connected to the mounting part 10. The front outer wall 21 is connected to the same side of the first left side wall 221, the second left side wall 222, and the third left side wall 223. The rear outer wall 23 is connected to the first left side wall 221. 1. On the other side of the second left side wall 222 and the third left side wall 223, the vibration damping tower 1 also includes a plurality of second reinforcing ribs 80, a plurality of third ejector pins 90, and a plurality of third reinforcing ribs 100. The plurality of second reinforcing ribs 80 are spaced apart and parallel to each other on the outer side of the second left side wall 222 and the third left side wall 223. The plurality of third ejector pins 90 are spaced apart and parallel to each other on the inner side of the second left side wall 222 and extend from the first left side wall 221 to the third left side wall 223. The plurality of third reinforcing ribs 100 are disposed between the second left side wall 222 and the left inner wall 32. Specifically, one end of the third reinforcing rib 100 is connected to the second left side wall 222 and the third ejector pin 90 located on the second left side wall 222, and the other end of the third reinforcing rib 100 is connected to the left inner wall 32 and the first ejector pin 40 located on the left inner wall 32.

[0056] By simultaneously connecting the inclined first left side wall 221 and third left side wall 223 to the vehicle body, not only is the connection stiffness between the damping tower 1 and the vehicle body improved, but the left outer wall 22 also forms two load transfer channels, thus improving the NVH performance of the damping tower 1. The stiffness of the left outer wall 22 is further enhanced by the installation of multiple second reinforcing ribs 80.

[0057] By setting the third ejector boss 90, demolding can be facilitated. Furthermore, the multiple third ejector bosses 90 are spaced apart and parallel to each other on the inner side of the second left side wall 222 and extend from the first left side wall 221 to the third left side wall 223. The multiple third ejector bosses 90 can become the skeleton of the second left side wall 222, thereby strengthening the second left side wall 222. At the same time, the second reinforcing rib 80 works together to improve the rigidity of the second left side wall 222.

[0058] In addition, multiple third reinforcing ribs 100 are provided between the second left side wall 222 and the left inner wall 32, which can provide mutual support between the second left side wall 222 and the inner reinforcing wall 30, further improving the rigidity of the second left side wall 222.

[0059] In some embodiments, see Figure 12 The mounting section 10 has a first mounting hole 11 and a plurality of second mounting holes 12 surrounding the first mounting hole 11. Specifically, the diameter of the first mounting hole 11 is larger than the diameter of the second mounting holes 12, and there are three second mounting holes 12. The vibration damping tower 1 also includes annular honeycomb reinforcing ribs 101 disposed on the mounting section 10 and located within the accommodating space 25. The annular honeycomb reinforcing ribs 101 are used to increase the strength of the mounting section 10. The annular honeycomb reinforcing rib 101 includes a first annular reinforcing rib 110, a second annular reinforcing rib 120, a plurality of first radial reinforcing ribs 130, a plurality of second radial reinforcing ribs 140, and a plurality of third radial reinforcing ribs 150. A plurality of second mounting holes 12 are provided on the first annular reinforcing rib 110. The second annular reinforcing ribs 120 are spaced apart on the outside of the first annular reinforcing ribs 110. The two ends of the second annular reinforcing ribs 120 are respectively connected to two of the plurality of second mounting holes 12. A plurality of first radial reinforcing ribs 130 are radially spaced between the first mounting holes 110 and the plurality of second mounting holes 12. A plurality of second radial reinforcing ribs 140 are spaced apart between the first annular reinforcing ribs 110 and the second annular reinforcing ribs 120. A plurality of third radial reinforcing ribs 150 are spaced apart between the edge of the mounting part 10 and the first annular reinforcing ribs 110, and between the second annular reinforcing ribs 120 and the edge of the mounting part 10.

[0060] Specifically, multiple first radial reinforcing ribs 130 are arranged in a ring. One end of each first radial reinforcing rib 130 is connected to the wall of the first mounting hole 11, and the other end is connected to the wall of the second mounting hole 12 or the first annular reinforcing rib 110. The second annular reinforcing rib 120 is semi-annular. One end of the second radial reinforcing rib 140 is connected to the wall of the second mounting hole 12 or the first annular reinforcing rib 110, and the other end is connected to the second annular reinforcing rib 120. Multiple third radial reinforcing ribs 150 are arranged in a ring.

[0061] The vibration damping tower 1 of this application embodiment has an internal reinforcing wall 30 provided inside the outer sidewall 20. The internal reinforcing wall 30 surrounds the front outer wall 21, rear outer wall 23, and left outer wall 22 of the vibration damping tower 1. That is, the front inner wall 31 is corresponding to the front outer wall 21, the rear inner wall 33 is corresponding to the rear outer wall 23, and the left inner wall 32 is corresponding to the left outer wall 22. The outer sidewall 20 and the internal reinforcing wall 30 can form an inner and outer double wall structure, which can form two relatively complete load transmission paths in the direction perpendicular to the mounting part 10, thereby improving the stiffness and NVH performance of the vibration damping tower 1. Furthermore, the other end of the front inner wall 31 forms a gap with the front outer wall 21. A first installation space 35 is formed, and a second installation space 37 is formed between the other end of the rear inner wall 33 and the rear outer wall 23. The first installation space 35 and the second installation space 37 can realize the two arms of the upper fork arm, satisfying the installation requirements of the upper fork arm. One end of the front inner wall 31 is connected to the front outer wall 21 to form a first wedge structure 34, and one end of the rear inner wall 33 is connected to the rear outer wall 23 to form a second wedge structure 36. The front inner wall 31 and the rear inner wall 33 not only constitute the second load transmission path of the vibration damping tower 1 in the direction perpendicular to the mounting part 10, but also provide support and reinforcement to the outer side wall 20, improving the rigidity of the vibration damping tower 1. In addition, this double-wall structure design not only meets the installation requirements of the upper fork arm, but also integrates the internal reinforcing wall 30 and the outer side wall 20 to form the first wedge structure 34 and the second wedge structure 36, improving the rigidity and other performance of the vibration damping tower 1 while reducing the weight of the vibration damping tower 1.
