[0033] With the continuous development of technology, people's demands for automobiles are also constantly increasing. When a car is driving on a bumpy road, the vibration is greater, which has a significant impact on the comfort of the vehicle.

[0034] To address the aforementioned technical problems, this application provides a vehicle including a suspension system that provides better shock absorption. The suspension system includes a shock absorber and a shock tower. The upper end of the shock absorber is connected to the shock tower, and the end of the shock tower away from the shock absorber is connected to a side beam to transmit external forces from the shock absorber to the side beam, thus achieving better shock absorption. The end of the shock tower away from the side beam can be connected to a longitudinal beam, thereby transmitting external forces from the shock absorber to the longitudinal beam. However, in the prior art, the structural strength of the shock tower is not high, and its effect in transmitting external forces is poor, resulting in poor shock absorption.

[0035] To address the aforementioned technical problems, this application provides a vibration damping tower, for details please refer to [link / reference needed]. Figure 1 and Figure 2 , Figure 1 This is a disassembled structural diagram of an embodiment of the shock-absorbing tower provided in this application. Figure 2 yes Figure 1 A first-view structural schematic diagram of one embodiment of the cover shown.

[0036] The shock absorber tower 10 includes a mounting body 100 and a cover 200. The mounting body 100 includes a mounting portion 110, which has shock absorber mounting positions 111 and weight reduction ports 112 spaced apart along a first direction X. The weight reduction ports 112 penetrate the opposite sides of the mounting portion 110 along a second direction Z, wherein the first direction X and the second direction Z intersect. The cover 200 covers the weight reduction ports 112 in the second direction Z and is connected to the mounting portion 110. The cover 200 includes a first force transmission surface 211 and a second force transmission surface 212 connected to each other. The first force transmission surface 211 faces the shock absorber mounting position 111 in the first direction X, and the second force transmission surface 212 faces away from the shock absorber mounting position 111 in the first direction X. The connection between the first force transmission surface 211 and the mounting portion 110 is at an obtuse angle, and the connection between the second force transmission surface 212 and the mounting portion 110 is at an obtuse angle.

[0037] One end of the mounting body 100 can be connected to a longitudinal beam, and the end of the mounting body 100 away from the longitudinal beam can be connected to a side beam. The mounting body 100 includes a mounting portion 110, which includes shock absorber mounting positions 111 and weight-reducing openings 112 spaced apart in a first direction X, which can be understood as the width direction of the shock absorber tower 10. The shock absorber mounting positions 111 are used to mount shock absorbers. The shock absorber tower 10 and the shock absorbers are part of the suspension system, which is connected to the wheels to ensure that the wheels are always in contact with the ground and to reduce vehicle bumps. The weight-reducing openings 112 can reduce the weight of the shock absorber tower 10, but they also reduce the structural strength of the shock absorber tower 10, especially in some models with high shock absorption requirements. Therefore, the structural strength of the shock absorber tower 10 needs to be improved.

[0038] The cover 200 covers the weight-reducing opening 112 in the second direction Z, and the periphery of the cover 200 is connected to the mounting part 110. The cover 200 compensates for the defect of the weight-reducing opening 112 in reducing the structural strength of the shock absorber tower 10, thereby improving the structural strength of the shock absorber tower 10. Here, the second direction Z can be understood as the height direction of the shock absorber tower 10. In this embodiment, the materials of the mounting body 100 and the cover 200 can be different. For example, the mounting body 100 can be an integral die-cast component, and the material can be magnesium alloy or aluminum alloy. Compared with traditional sheet metal shock absorber towers, it has higher integration, lighter weight, and better performance. The cover 200 can be a thermoformed sheet metal part. Therefore, by setting the cover 200 separately and connecting it to the mounting part 110, the cover 200 and the mounting body 100 can be made of different materials, which is more convenient for manufacturing processes. In addition, for models with low shock absorption requirements, the shock absorber tower 10 without the connecting cover 200 can be used directly. For models with high shock absorption requirements, the cover 200 can be connected to the shock absorber tower 10 with the weight reduction port 112, thereby improving the structural strength of the shock absorber tower 10. There is no need to re-prepare the production mold, thus reducing production costs.

[0039] Specifically, the cover 200 includes a force-transmitting part 210, which includes a first force-transmitting surface 211 and a second force-transmitting surface 212. The first force-transmitting surface 211 is closer to the shock absorber mounting position 111, and the second force-transmitting surface 212 can be connected to the end of the first force-transmitting surface 211 that is away from the shock absorber mounting position 111. The first force-transmitting surface 211 faces the shock absorber mounting position 111 in a first direction X, and the second force-transmitting surface 212 faces away from the shock absorber mounting position 111 in the first direction X. Furthermore, the included angle between the connection between the first force-transmitting surface 211 and the mounting portion 110 is α, and the included angle between the second force-transmitting surface 212 and the mounting portion 110 is β. Both angles α and β are obtuse angles, causing the connection between the first force-transmitting surface 211 and the second force-transmitting surface 212 to protrude beyond the mounting portion 110 in the second direction Z. Also, from the ends of the first force-transmitting surface 211 and the second force-transmitting surface 212 in the first direction X to their connection point, the distance between the first force-transmitting surface 211 and the second force-transmitting surface 212 and the mounting portion 110 gradually increases in the second direction Z. This allows the external force on the shock absorber to be transmitted to the cover 200 through the shock absorber mounting position 111. The specific force transmission path is as follows: the shock absorber mounting position 111 transmits the external force in the first direction X to the inclined first force transmission surface 211, then the second force transmission surface 212 and the mounting part 110. The end of the mounting part 110 away from the shock absorber mounting position 111 in the first direction X is connected to the side beam of the vehicle body, thereby transmitting the external force to the side beam and playing a shock absorption role.

[0040] As an example, the first force-transmitting surface 211 and the second force-transmitting surface 212 can be arc-shaped. It is sufficient that the angle between the entire first force-transmitting surface 211 and the mounting portion 110 is an obtuse angle, and the angle between the entire second force-transmitting surface 212 and the mounting portion 110 is also an obtuse angle. This allows for a larger cavity volume formed between the first force-transmitting surface 211 and the second force-transmitting surface 212, increasing the ability to absorb external force energy and improving the vibration damping effect. As another example, the first force-transmitting surface 211 and the second force-transmitting surface 212 can be inclined surfaces; or at least the main body of the first force-transmitting surface 211 and the second force-transmitting surface 212 is inclined, meaning that the distance between the first force-transmitting surface 211 and the second force-transmitting surface 212 and the mounting portion 110 increases linearly from the end where they are far apart to the end where they are connected. The inclined surface shortens the force transmission path and increases the structural strength of the cover 200, thereby improving the vibration damping effect.

[0041] In the above-described embodiment, the cover 200 is disposed adjacent to the shock absorber mounting position 111 in the first direction X. The cover 200 includes a first force transmission surface 211 and a second force transmission surface 212. The first force transmission surface 211 and the second force transmission surface 212 are oriented opposite to each other in the first direction X, and the first force transmission surface 211 and the second force transmission surface 212 are respectively obtuse angles with the connection of the mounting part 110, so that the external force received by the shock absorber mounting position 111 can be transmitted sequentially through the first force transmission surface 211 and the second force transmission surface 212 to the side beam connected to the shock absorber tower 10. Furthermore, the first force transmission surface 211 and the second force transmission surface 212 are inclined in opposite directions, which allows the external force at the damper mounting position 111 to be first transmitted to the first force transmission surface 211 in the first direction X. The external force is then transmitted upward along the first force transmission surface 211 to the second force transmission surface 212, and then downward along the second force transmission surface 212 to the mounting part 110. Therefore, the external force follows a transmission path that is first inclined upward and then inclined downward, which effectively disperses the external force at the connection between the first force transmission surface 211 and the second force transmission surface 212. This not only improves the structural strength of the damping tower 10, but also improves the ability of the damping tower 10 to transmit and disperse external forces, thereby improving the damping effect.

[0042] In some embodiments, the second force transmission surface 212 is an arc surface, and the second force transmission surface 212 bends in the first direction X toward the side opposite to the first force transmission surface 211.

[0043] The side where the first force transmission surface 211 connects to the second force transmission surface 212 is curved. The curved side of the first force transmission surface 211 bends away from the damper mounting position 111. The second force transmission surface 212 is also curved, and it bends away from the first force transmission surface 211 in the first direction X. The curved second force transmission surface 212 and the curved side of the first force transmission surface 211 are connected accordingly, allowing the cover 200 to form a triangular pyramid-like structure, which improves the structural strength of the cover 200 itself. Furthermore, the curved shape of the second force transmission surface 212 increases the connection boundary between the second force transmission surface 212 and the mounting portion 110. Between the second force transmission surface 212 and the mounting portion 110, the external force transmitted from the second force transmission surface 212 to the mounting portion 110 can be further dispersed, thereby improving the damping tower 10's ability to transmit external forces and enhancing the damping effect.

[0044] In some embodiments, the cover 200 may include an arc-shaped connecting surface, the two ends of which connect a first force-transmitting surface 211 and a second force-transmitting surface 212 in a first direction X, and the center of the arc of the arc-shaped connecting surface is located on the side closer to the mounting portion 110 in a second direction Z. Thus, the arc-shaped connecting surface connects the first force-transmitting surface 211 and the second force-transmitting surface 212, thereby reducing the stress between the first force-transmitting surface 211 and the second force-transmitting surface 212 when external forces are transmitted between them, and improving the overall structural strength of the first force-transmitting surface 211 and the second force-transmitting surface 212.

[0045] In some embodiments, the first force transmission surface 211 includes a force transmission main surface 2111 and a force transmission convex surface 2112, the force transmission convex surface 2112 is connected to the force transmission main surface 2111, and the force transmission convex surface 2112 corresponds to the curvature of the second force transmission surface 212 in the first direction X.

[0046] Because the second force-transmitting surface 212 is arc-shaped, the external force on the first force-transmitting surface 211 will be more concentrated at the position corresponding to the curvature of the second force-transmitting surface 212 in the first direction X, making the first force-transmitting surface 211 more susceptible to deformation and fracture. To solve the above problem, the first force-transmitting surface 211 includes a main force-transmitting surface 2111 and a convex force-transmitting surface 2112. The main force-transmitting surface 2111 is connected to the convex force-transmitting surface 2112. The convex force-transmitting surface 2112 protrudes from the main force-transmitting surface 2111 in the second direction Z, and the convex force-transmitting surface 2112 corresponds to the curvature of the second force-transmitting surface 212 in the first direction X. As an example, the dimension of the force-transmitting convex surface 2112 in the first direction X can be smaller than the dimension of the portion of the first force-transmitting surface 211 and the force-transmitting convex surface 2112 corresponding to it in the first direction X. One side of the force-transmitting convex surface 2112 is connected to the second force-transmitting surface 212, and the main force-transmitting surface 2111 is arranged around the remaining portion of the force-transmitting convex surface 2112. As another example, the dimension of the force-transmitting convex surface 2112 in the first direction X is equal to the dimension of the portion of the first force-transmitting surface 2111 and the force-transmitting convex surface 2112 corresponding to it in the first direction X. One side of the force-transmitting convex surface 2112 is connected to the second force-transmitting surface 212, so that the force-transmitting convex surface 2112 divides the main force-transmitting surface 2111 into two parts in the third direction Y. The third direction Y can be understood as the length direction of the damping tower 10. Therefore, the structural strength of the portion of the first force-transmitting surface 211 corresponding to the bend of the second force-transmitting surface 212 in the first direction X can be improved, thereby improving the structural strength and damping effect of the damping tower 10. The dimensions of the force-transmitting convex surface 2112 in the first direction X can be adjusted according to actual conditions, and this application does not limit it here.

[0047] See Figure 3 , Figure 3 yes Figure 2 The diagram shows a cross-sectional view of the cap along the BB direction.

[0048] In some embodiments, the angle between the connection between the first force transmission surface 211 and the mounting portion 110 is greater than the angle between the connection between the second force transmission surface 212 and the mounting portion 110.

[0049] The angle between the connection between the first force-transmitting surface 211 and the mounting portion 110 is 'a', and the angle between the connection between the second force-transmitting surface 212 and the mounting portion 110 is 'b', both angles 'a' and 'b' being obtuse. Furthermore, the angle 'a' is greater than the angle 'b', resulting in a smaller tilt angle of the first force-transmitting surface 211 relative to the mounting portion 110 and a larger tilt angle of the second force-transmitting surface 212 relative to the mounting portion 110, thereby further improving the structural strength of the cover 200 itself. In addition, the smaller tilt angle of the first force-transmitting surface 211 relative to the mounting portion 110 allows for smoother transmission of external forces, and the external force can be more effectively dispersed at the connection between the first force-transmitting surface 211 and the second force-transmitting surface 212. Therefore, the ability of the cover 200 to transmit and disperse external forces can be further improved, enhancing the shock absorption effect.

[0050] In some embodiments, the cover 200 includes two first connecting portions 213 and a force transmitting portion 210. A first force transmitting surface 211 and a second force transmitting surface 212 are located on the force transmitting portion 210. The two first connecting portions 213 are respectively connected to the two ends of the force transmitting portion 210 in the third direction Y. Each first connecting portion 213 is higher than at least part of the first force transmitting surface 211 and the second force transmitting surface 212 in the second direction Z. The first direction X, the second direction Z and the third direction Y intersect each other.

[0051] The cover 200 includes a first connecting portion 213 and a force transmitting portion 210. The force transmitting portion 210 is used to transmit external forces from the shock absorber mounting position 111. The force transmitting portion 210 includes a first force transmitting surface 211 and a second force transmitting surface 212. Therefore, the force transmitting portion 210 mainly transmits external forces through the first force transmitting surface 211 and the second force transmitting surface 212. The two first connecting portions 213 are respectively connected to one end of the force transmitting portion 210 in the third direction Y, and each first connecting portion 213 is higher than at least part of the first force transmitting surface 211 and the second force transmitting surface 212 in the third direction Y, so that different parts of the cover 200 have a height difference, thereby further improving the structural strength of the cover 200. In this embodiment, the ends of the two first connecting portions 213 that are far from each other are arc-shaped, which can reduce the stress of the cover 200 at the first connecting portion 213, thereby improving the fatigue life, static strength and resistance to brittle fracture at the first connecting portion 213. Furthermore, the first connecting portion 213 can be disposed opposite to the mounting portion 110, that is, the first connecting portion 213 and the mounting portion 110 are nearly parallel, thereby creating a structural difference between the first connecting portion 213 and the first force transmission surface 211 and the second force transmission surface 212, which can further improve the structural strength of the cover 200.

[0052] Of course, in some other embodiments, the surfaces of the two first connecting portions 213 may also be formed by extending from both ends of the first force transmission surface 211 and the second force transmission surface 212 in a third direction Y. That is, part of the surface of the two first connecting portions 213 matches the inclination angle of the first force transmission surface 211, and part of the surface may also match the second force transmission surface 212, and be higher than part of the first force transmission surface 211 and the second force transmission surface 212 in the second direction Z.

[0053] See Figure 4 , Figure 4 yes Figure 1 An enlarged structural diagram of the shock-absorbing tower at point A (dashed circle).

[0054] In some embodiments, the mounting part 110 is provided with two second connecting parts 113, which are located at both ends of the weight reduction port 112 in the third direction Y, and a first connecting part 213 is connected to a corresponding second connecting part 113.

[0055] The mounting part 110 is provided with two second connecting parts 113, which are located at both ends of the weight reduction port 112 in the third direction Y, and cover part of the weight reduction port 112. Each of the two second connecting parts 113 is connected to a corresponding first connecting part 213. The connection interface between the second connecting part 113 and the first connecting part 213 is compatible, resulting in a higher fit between the first connecting part 213 and the second connecting part 113, which is more conducive to force transmission. The first connecting part 213 and the second connecting part 113 are respectively provided with corresponding first mounting holes and second mounting holes. The first connecting part 213 can be connected to the second connecting part 113 by bolts passing through the first mounting holes and second mounting holes. Furthermore, the periphery of the first connecting portion 213 extends toward the mounting portion 110 in the second direction Z and connects with the mounting portion 110. The radial dimension of the first connecting portion 213 can be larger than the radial dimension of the second connecting portion 113, thereby forming an annular cavity between the outer periphery of the second connecting portion 113 and the inner periphery of the first connecting portion 213, which can improve the structural strength after the first connecting portion 213 and the second connecting portion 113 are connected.

[0056] In some embodiments, a connecting edge is formed on the outer periphery of the cover 200 to match and connect with the surface of the mounting portion 110. The connecting edge is also arranged around the edges of the two first connecting portions 213, the first force transmission surface 211, and the second force transmission surface 212. Structural adhesive is provided between the connecting edge and the surface of the mounting portion 110, so that the connecting edge can be bonded to the mounting portion 110, thereby improving the connection strength between the cover 200 and the mounting portion 110, and also absorbing the vibration energy between the cover 200 and the mounting portion 110, reducing noise transmission.

[0057] In some embodiments, the side of each second connecting portion 113 near the weight reduction port 112 is an arc-shaped edge 1131, the center of the arc of the arc-shaped edge 1131 is located in the weight reduction port 112, and the arc-shaped edge 1131 of each second connecting portion 113 is connected to the edge of the weight reduction port 112.

[0058] Therefore, the center of the arc of the arc-shaped edge 1131 of the second connecting portion 113 is located at the weight-reducing opening 112, and the arc-shaped edge 1131 is connected to the edge of the weight-reducing opening 112, making the force transmission at the second connecting portion 113 smoother and reducing the local stress of the second connecting portion 113. In this embodiment, the edge of the weight-reducing opening 112 has a curved flange, and the opposite two side surfaces of the curved flange are curved, thereby reducing the local stress at the edge of the weight-reducing opening 112. The arc-shaped edge 1131 can be transitionally connected to the curved flange, that is, the connection between the arc-shaped edge 1131 and the curved flange is also arc-shaped, thereby making the force transmission between the first connecting portion 213 and the weight-reducing opening 112 smoother. In addition, the first connecting portion 213 can also be higher than the curved flange in the second direction Z, which can improve the structural strength at both ends of the weight-reducing opening 112 in the third direction Y.

[0059] In some embodiments, the cover 200 includes a third connecting portion 214, which is connected to the force transmission portion 210 on the side away from the shock absorber mounting position 111 in a first direction X, and the third connecting portion 214 is connected to the mounting portion 110.

[0060] like Figure 2 As shown, the third connecting portion 214 is disposed on the side of the force transmission portion 210 away from the shock absorber mounting position 111 in the first direction X, and the third connecting portion 214 is connected to the mounting portion 110. The side of the cover 200 closer to the shock absorber mounting position 111 will bear greater external force. Therefore, the two first connecting portions 213 are closer to the shock absorber mounting position 111 than the third connecting portion 214, which makes the cover 200 more firmly fixed. Moreover, the third connecting portion 214 and the two first connecting portions 213 are arranged in a triangle, which makes the stability of the cover 200 better. Furthermore, the third connecting portion 214 can form an isosceles triangle with the two first connecting portions 213, that is, the third connecting portion 214 is located on the perpendicular bisector of the line connecting the two first connecting portions 213, thereby making the force on the cover 200 more even.

[0061] See Figure 5 , Figure 5 This is a first-view structural schematic diagram of an embodiment of the shock-absorbing tower provided in this application.

[0062] In some embodiments, the mounting body 100 includes a support portion 120, which is disposed around the mounting portion 110 in a second direction Z, and the cover 200 protrudes from the mounting portion 110 on the side opposite to the support portion 120 in the second direction Z.

[0063] The mounting body 100 includes a mounting portion 110 and a support portion 120. The support portion 120 is arranged around the mounting portion 110 in a second direction Z, thereby forming a receiving cavity between the mounting portion 110 and the support portion 120. The receiving cavity can be used to accommodate a shock absorber. In some embodiments, the receiving cavity can also accommodate components such as a double wishbone, with the double wishbone and the shock absorber spaced apart in the first direction X. During vehicle operation, the double wishbone will swing within a certain range, causing interference between the double wishbone and the mounting portion 110. A weight-reducing opening 112 is arranged in the second direction Z corresponding to the double wishbone, and the range of the weight-reducing opening 112 can be larger than the swing range of the double wishbone. The arrangement of the weight-reducing opening 112 can minimize the interference of the double wishbone on the mounting portion 110. Furthermore, a cover 200 can be provided on the side of the mounting portion 110 opposite to the support portion 120, i.e., on the upper side of the mounting portion 110. The cover 200 is arched, that is, the structure formed by the first force transmission surface 211 and the second force transmission surface 212, so that the cover 200 has a relief groove on the side near the double fork arm. Thus, the cover 200 protruding from the mounting part 110 in the second direction Z can not only improve the structural strength of the shock absorber tower 10, but also avoid the swing of the double fork arm.

[0064] In some embodiments, the support portion 120 includes a plurality of reinforcing steps 123 located at both ends of the shock absorber mounting position 111 in the third direction Y. The plurality of reinforcing steps 123 are sequentially arranged in the second direction Z in a direction away from the shock absorber mounting position 111. That is, among at least two adjacent reinforcing steps 123 at one end of the shock absorber mounting position 111, the reinforcing step 123 closer to the shock absorber mounting position 111 is higher than the adjacent reinforcing step 123 in the second direction Z. This improves the structural strength of the shock absorber tower 10.

[0065] Specifically, the support portion 120 includes a first support portion 121 and a second support portion 122, which are connected. The first support portion 121 is arranged around the mounting portion 110, and the second support portion 122 extends in the second direction Z and connects to the mounting portion 110 and the end of the first support portion 121 near the shock absorber mounting position 111 in the first direction X. The first support portion 121 has multiple first steps extending in the first direction X, and the second support portion 122 has multiple second steps extending in the second direction Z. The multiple first steps are located at both ends of the shock absorber mounting position 111 in the third direction Y, and the multiple second steps are located at both ends of the shock absorber mounting position 111 in the third direction Y. One first step corresponds to one second step. This improves the overall structural strength of the shock absorber tower 10.

[0066] See Figure 6 , Figure 6This is a second-view structural schematic diagram of an embodiment of the shock-absorbing tower provided in this application.

[0067] In some embodiments, the first support portion 121 is provided with a first reinforcing rib 124 and two second reinforcing ribs 125 on the side near the receiving cavity. The first reinforcing rib 124 is arranged around the shock absorber mounting position 111, and the second reinforcing ribs 125 extend in the first direction X. The two second reinforcing ribs 125 are spaced apart from the first reinforcing rib 124 in the third direction Y, and are respectively located on one side of the first reinforcing rib 124 in the third direction Y. One end of the first reinforcing rib 124 and the second reinforcing rib 125 is also connected to the first support portion 121 and the second support portion 122. This can improve the connection strength between the first support portion 121 and the second support portion 122, and improve the structural strength of the shock absorber tower 10. In addition, at least a portion of the first reinforcing rib 124 and the second reinforcing rib 125 corresponds to the connection between two adjacent reinforcing steps 123 in the second direction Z, and external forces can be transmitted along the first reinforcing rib 124 and the second reinforcing rib 125. Therefore, the arrangement of the first reinforcing rib 124 and the second reinforcing rib 125 can not only improve the structural strength of the damping tower 10, but also improve the force transmission capacity of the damping tower 10 and improve the damping effect of the damping tower 10.

[0068] In some embodiments, the first support portion 121 further includes a plurality of third reinforcing ribs 126, which are connected between adjacent first reinforcing ribs 124 and second reinforcing ribs 125 and between the second reinforcing ribs 125 and the edge of the first support portion 121. The plurality of third reinforcing ribs 126 may also be arranged in a crisscross pattern, thereby effectively improving the structural strength of the shock absorber tower 10.

[0069] See Figure 7 , Figure 7 yes Figure 1 A second-view structural schematic diagram of one embodiment of the cover shown.

[0070] In some embodiments, the cover 200 includes a clearance portion 220 disposed on the outer periphery of the cover 200. The clearance portion 220 includes a clearance opening 221 and a reinforcing plate 222 disposed around the clearance opening 221. The reinforcing plate 222 protrudes along the orientation direction of the clearance opening 221. The clearance opening 221 is used for threading wire harnesses, and the reinforcing plate 222 can improve the structural strength around the clearance opening 221. There can be multiple clearance portions 220, and the orientations of the clearance openings 221 of the multiple clearance portions 220 can be different, thereby allowing for the threading of wire harnesses from different directions.

[0071] In summary, the cover 200 is disposed adjacent to the shock absorber mounting position 111 in the first direction X. The cover 200 includes a first force transmission surface 211 and a second force transmission surface 212. The first force transmission surface 211 and the second force transmission surface 212 are oriented oppositely in the first direction X, and the first force transmission surface 211 and the second force transmission surface 212 respectively form obtuse angles with the connection of the mounting part 110, so that the external force received by the shock absorber mounting position 111 can be transmitted sequentially through the first force transmission surface 211 and the second force transmission surface 212, and then transmitted to the side beam connected to the shock absorber tower 10. Furthermore, the first force transmission surface 211 and the second force transmission surface 212 are inclined in opposite directions, which allows the external force at the damper mounting position 111 to be first transmitted to the first force transmission surface 211 in the first direction X. The external force is then transmitted upward along the first force transmission surface 211 to the second force transmission surface 212, and then downward along the second force transmission surface 212 to the mounting part 110. Therefore, the external force follows a transmission path that is first inclined upward and then inclined downward, which effectively disperses the external force at the connection between the first force transmission surface 211 and the second force transmission surface 212. This not only improves the structural strength of the damping tower 10, but also improves the ability of the damping tower 10 to transmit and disperse external forces, thereby improving the damping effect.
