AI Technical Summary
During use, existing automotive hood struts can cause damage to the coating by rubbing against the holes in the inner hood panel, leading to rust and shortening the service life.
A support rod reinforcement plate is welded to the inner panel of the front hood, and the support rod is used to clip the cover into the through hole to avoid direct contact between the support rod and the through hole. The plastic support rod cover also buffers the impact force.
By enhancing structural stability and shock absorption, the lifespan of the struts is significantly extended, maintenance costs are reduced, and the user experience is improved.

Abstract
Description
Technical Field
[0001] This utility model relates to the technology of improving the service life of front hood support rods, and in particular to a structure for improving the service life of front hood support rods. Background Technology
[0002] Currently, most cars use two types of hood support: mechanical struts and hydraulic struts. Mechanical struts are typically metal rods that support the hood by rotating. When using mechanical struts to support the hood, one end of the strut is inserted into a fixed point, and the other end passes through a hole in the inner hood panel and rests on the corresponding position on the inner hood panel. During the process of the strut passing through the hole in the inner hood panel, the strut and the hole are prone to scratching, which can damage the strut's coating, causing rust and shortening the strut's lifespan. Utility Model Content
[0003] Purpose of the utility model: The purpose of this utility model is to provide a structure that improves the service life of the front hood support rod. A support rod reinforcing plate is welded to the through hole of the support rod on the inner plate of the front hood, and the support rod is used to support the cover and snap it into the through hole. During the process of inserting the support rod into the through hole, the support rod does not directly contact the through hole, which solves the problem of rust caused by the damage of the support rod coating due to scratching, and improves the service life of the support rod.
[0004] Technical solution: A structure for improving the service life of a front hood strut, comprising a strut, a front hood inner panel, a strut reinforcing plate, and a strut support cover, wherein the strut reinforcing plate is fixedly connected to the front hood inner panel by welding.
[0005] Furthermore, the strut reinforcement plate is a sheet metal part, and its shape is a flat plate. A square hole is opened on the top of the strut reinforcement plate, and the strut support cover is snapped into the square hole.
[0006] Furthermore, the strut support cover is made of plastic.
[0007] Beneficial Effects: This structure, which extends the lifespan of the hood strut, offers significant benefits. The welded connection between the strut reinforcement plate and the inner hood panel greatly strengthens the hood structure, ensuring stable support for the strut and reducing additional wear caused by structural instability. The strut support cover, made of plastic, effectively cushions the impact on the strut ends during hood opening and closing, preventing wear and deformation caused by rigid collisions. Working together, these two components address both structural stability and impact cushioning, comprehensively reducing damage to the strut during frequent use, significantly extending its lifespan, lowering vehicle maintenance costs, and enhancing the user experience.

[0013] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0014] Example
[0015] like Figures 1-4 As shown, a structure for improving the service life of a front hood strut is provided, including a strut 1, a front hood inner plate 2, a strut reinforcing plate 4, and a strut support cover 3. The strut reinforcing plate 4 is fixedly connected to the front hood inner plate 2 by welding. The strut reinforcing plate 4 is a sheet metal part with a flat plate shape. A square hole 5 is provided on the top of the strut reinforcing plate 4. The strut support cover 3 is snapped into the square hole 5. The strut support cover 3 is a plastic part.
[0016] The flat sheet metal strut reinforcement plate 4 is firmly connected to the inner panel of the hood 2 by welding. This operation greatly enhances the structural strength of the inner panel of the hood 2, laying a solid foundation for the stable operation of the strut 1. Above the strut reinforcement plate 4, the pre-drilled square hole 5 is an important interface for connecting the strut support cover 3. Next, the plastic strut support cover 3 is precisely inserted into the square hole 5, completing a tight and reliable assembly. When the hood is opened during daily use, one end of the strut 1 presses against the strut support cover 3, and the strut 1 bears considerable pressure. At this time, the plastic strut support cover 3, with its own softness, effectively buffers the impact force at the end of the strut 1, preventing the strut from wearing and deforming due to rigid impact, thereby significantly improving the service life of the strut.
[0017] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
