Description

Technical Field

[0001] This application relates to the field of vibration damping tower technology, and in particular to a lightweight, high-strength vibration damping tower component for new energy vehicles. Background Technology

[0002] The shock absorber tower is a key safety component in the vehicle body structure. It is located in the engine compartment, with the upper part connected to the shock absorber of the suspension system and the lower part connected to the longitudinal beams of the body, wheel arches and other structures. It mainly bears and transmits complex alternating loads from the wheels, including impact forces, vibrations and lateral forces.

[0003] Existing shock absorber towers are too heavy to meet the lightweight design requirements of automobiles; furthermore, a certain level of strength must also be maintained. Additionally, when installing shock absorber towers inside the vehicle, other components need to be stacked on top of them, but traditional shock absorber towers with their curved surface structure struggle to provide stable support for these components. Therefore, there is an urgent need in this field for a shock absorber tower component specifically designed for new energy vehicles. This component should be able to significantly reduce weight while comprehensively improving stiffness and strength through innovative structural design, and should also integrate multiple installation functions to achieve a balance between structural performance and ease of assembly.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0021] In the embodiments of this application, please refer to Figure 1-3 As shown, this lightweight, high-strength shock absorber tower component for new energy vehicles mainly includes: a shock absorber tower body 1, the base of which forms a multi-level stepped structure composed of multiple L-shaped steps 2, the top of which has multiple mounting holes 3, and multiple mounting plates 4 horizontally arranged on which the mounting holes 3 and fasteners cooperate. Multiple reinforcing ribs are radially distributed on the outer wall of the shock absorber tower body 1. The multi-level stepped structure effectively improves the overall impact resistance of the structure by distributing the load step by step; while the reinforcing ribs further enhance the circumferential stiffness of the shock absorber. In the longitudinal section of the shock absorber tower body 1, the L-shaped steps 2 have an L-shaped cross-section.

[0022] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0023] Furthermore, the L-shaped steps 2 are circumferentially formed on the damping tower body 1, and multiple L-shaped steps 2 gradually converge from the bottom to the top of the damping tower body 1, which enables the damping tower to form a stable conical support system in the vertical direction. The damping tower body 1 is integrally cast.

[0024] Furthermore, the L-shaped step 2 includes an integral horizontal step surface 201 and an arc-shaped step surface 202. The connection between the horizontal step surface 201 and the arc-shaped step surface 202 is rounded. The assembly hole 3 is opened on the horizontal step surface 201. The angle between the horizontal step surface 201 and the arc-shaped step surface 202 is 110-120 degrees.

[0025] Furthermore, a horizontal support ring 5 is formed on the top of the main body 1 of the shock absorber tower. The horizontal support ring 5 and the multi-level stepped structure are connected by a transition arc surface 6, which can effectively eliminate stress concentration and improve the strength and fatigue life of the parts.

[0026] Furthermore, the transition arc surface 6 is provided with multiple mounting holes 3 in the circumferential direction. The curvature of the outer wall of the transition arc surface 6 is small, which allows automotive components such as wiring harness clips to be installed through the mounting holes 3 and fasteners. The horizontal support ring 5 is provided with multiple through upper mounting holes 7 in the ring. The upper mounting holes 7 can provide space for positioning and installation of vehicle shock absorbers.

[0027] Furthermore, the reinforcing ribs include first reinforcing ribs 9 and second reinforcing ribs 10 arranged in a ring with equal spacing. The first reinforcing ribs 9 extend from the outer edge of the damping tower body 1 to the outer edge of the horizontal support ring 5. The second reinforcing ribs 10 are arranged on the multi-level stepped structure, with a single second reinforcing rib 10 positioned between two first reinforcing ribs 9. The first reinforcing ribs 9 serve as the main load-bearing ribs, providing the main longitudinal stiffness. The second reinforcing ribs 10 serve as secondary reinforcing ribs, filling the spaces between the first reinforcing ribs 9, and together they provide supplementary strength to the damping tower body 1.

[0028] Furthermore, an outer edge extension plate 11 is provided circumferentially on the base of the shock absorber tower body 1. Multiple lower mounting holes 8 are equally spaced on the outer edge extension plate 11. The outer edge extension plate 11 effectively increases the connection area with the vehicle body longitudinal beam or chassis frame, and can transmit the impact force more smoothly when subjected to longitudinal impact force. At the same time, it also provides installation space for the shock absorber tower to be bolted or riveted.

[0029] Furthermore, in order to conform to the lightweight design concept, the main body 1 of the shock absorber tower is made of aluminum alloy.

[0030] The various embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
