Description

Technical Field

[0001] This utility model relates to the technical field of automotive connectors, specifically a flange for automotive shock absorption systems. Background Technology

[0002] During vehicle operation, the flange end face of the flange will bear a large amount of axial stress. Existing flanges are generally single flange structures, that is, only one flange part is connected to the rod part in a two-layer frustum structure. During stress transmission, the stress of the frustum of the upper flange part is directly transmitted to the frustum of the rod part. This stress transmission method can easily lead to plastic deformation or even fracture at the joint between the flange frustum and the rod part, thus affecting the safe driving of the vehicle. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a flange part for automotive shock absorption system, which reduces the risk of stress concentration between the flange part and the rod part, thereby reducing the risk of plastic deformation or even fracture, and thus improving the safe use performance of the product.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A flange for an automotive shock absorption system includes a flange portion, a buffer support portion, and a rod portion coaxially arranged from top to bottom. The outer diameter of the flange portion is larger than the outer diameter of the buffer support portion, and the outer diameter of the buffer support portion is larger than the outer diameter of the rod portion. It also includes a through hole penetrating the flange portion, the buffer support portion, and the rod portion.

[0006] Furthermore, a first connection angle is formed at the end face connection between the flange and the buffer support, and at the end face connection between the buffer support and the rod.

[0007] Furthermore, the first connecting angle is arc-shaped.

[0008] Furthermore, guide slopes are formed between the end faces of the through hole and the flange, and between the through hole and the end face of the rod.

[0009] Furthermore, the stepped surfaces of the flange, the buffer support, and the rod, and their corresponding outer ring walls are rounded.

[0010] Furthermore, the flange portion has multiple raised strips on its end face, which are arranged radially around the axis of the flange portion.

[0011] Furthermore, the cross-section of the convex strip is triangular.

[0012] Furthermore, the top of the convex strip is rounded.

[0013] Furthermore, the end faces of the protrusion and the flange portion form a second connection angle.

[0014] Furthermore, the second connecting angle is arc-shaped.

[0015] Compared with the prior art, the present invention has the following beneficial effects: the flange has a stepped multi-frustum structure, which can transmit part of the stress to the buffer support and the rod when the flange is subjected to axial stress, thereby reducing the stress at the junction of the two frustums; reducing the risk of stress concentration between the flange and the rod, which may lead to plastic deformation or even fracture, thereby improving the safe use performance of the product.

[0024] like Figure 1-3 As shown, this embodiment provides a flange for an automotive shock absorption system, including a flange portion 11, a buffer support portion 12, and a rod portion 13 coaxially arranged from top to bottom. The outer diameter of the flange portion 11 is larger than the outer diameter of the buffer support portion 12, and the outer diameter of the buffer support portion 12 is larger than the outer diameter of the rod portion 13, so that the outer contour of the flange has a stepped multi-frustum structure. The flange also includes a through hole 101 penetrating the flange portion 11, the buffer support portion 12, and the rod portion 13, and the through hole 101 is used for assembly and positioning with the other component.

[0025] The flange has a stepped multi-frustum structure, which can distribute some of the stress to the buffer support 12 and the rod 13 when the flange 11 is subjected to axial stress, thereby reducing the stress at the junction of the two frustums and reducing the risk of stress concentration between the flange 11 and the rod 13, which may lead to plastic deformation or even fracture, thus improving the safe use performance of the product.

[0026] like Figure 1-3 As shown, furthermore, a first connecting angle is formed at the end face connection between the flange portion 11 and the buffer support portion 12, and at the end face connection between the buffer support portion 12 and the rod portion 13. The first connecting angle is arc-shaped, which can improve the rigidity between the flange portion 11, the buffer support portion 12 and the rod portion 13, and facilitate the transmission of stress.

[0027] like Figure 1-3 As shown, furthermore, guide slopes 102 are formed between the end faces of the through hole 101 and the flange portion 11, and between the end faces of the through hole 101 and the rod portion 13. The guide slopes 102 can guide the handpiece when it passes through the through hole 101, which is beneficial to the assembly and use of the handpiece and the flange.

[0028] like Figure 1-3As shown, furthermore, the stepped surfaces of the flange portion 11, the buffer support portion 12, and the rod portion 13, and their corresponding outer ring walls are rounded.

[0029] like Figure 1 As shown, as a preferred embodiment, the flange 11 has a plurality of protrusions 14 on its end face, and the protrusions 14 are arranged radially around the axis of the flange 11. The design of the protrusions 14 increases the fastening performance between the corresponding parts, making it extremely difficult for them to slip relative to each other in a vibration environment, thereby improving the safety of the vehicle's shock absorption system.

[0030] like Figure 4 As shown, the cross-section of the protrusion 14 is triangular.

[0031] like Figure 4 As shown, preferably, the top end of the protrusion 14 is rounded, and the end faces of the protrusion 14 and the flange portion 11 form a second connecting angle, which is arc-shaped.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
