Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a high-strength lightweight front wheel arch reinforcement plate for automobiles. Background Technology

[0002] The front wheel arch is an essential part of the vehicle's underbody and plays a crucial role in the overall vehicle structure. Besides providing mounting support for the front suspension and other accessories such as wiring harnesses, it also significantly impacts the overall rigidity, modal characteristics, and crash performance of the vehicle. Currently, automotive front wheel arches are typically a single sheet metal piece. To facilitate stamping, materials with low yield strength and thin thickness are usually chosen, resulting in relatively low strength for the front wheel arch itself.

[0003] Chinese patent CN210734310U discloses a front wheel arch reinforcement plate, which includes a sheet metal shell formed by stamping. The sheet metal shell includes a sloping baffle portion that partially surrounds the rear side of the front wheel, an arc-shaped plate portion that is curvedly connected to the lower end of the sloping baffle portion, and a straight baffle portion that extends from the arc-shaped plate portion and is away from the front wheel. This patent uses the sloping baffle portion and the arc-shaped plate portion to cooperate in covering the front wheel, while the straight baffle portion is equipped with a shock absorber. The arc-shaped convex strip strengthens the arc-shaped plate portion, which plays a connecting role, simplifying the reinforcement and avoiding the problem of cracking that is common in previous front wheel arches.

[0004] The aforementioned patented front wheel arch reinforcement plate cannot maintain stable structural strength during actual use, and its excessive weight affects vehicle stability and is not conducive to long-term use. Therefore, it does not meet current needs. In response, we propose a high-strength lightweight front wheel arch reinforcement plate for automobiles. Utility Model Content

[0005] The purpose of this utility model is to provide a high-strength, lightweight front wheel arch reinforcement plate for automobiles, which solves the problems mentioned in the background art, such as the inability to maintain stable structural strength during actual use, and the excessive weight of the reinforcement plate affecting vehicle stability and being unsuitable for long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength lightweight front wheel arch reinforcement plate for automobiles, comprising a reinforcement plate body, the reinforcement plate body comprising a protrusion, two outer reinforcement plates and a buffer ridge, the buffer ridge being disposed between the two outer reinforcement plates, the protrusion being disposed at the upper end of the buffer ridge, a plurality of outer support portions being disposed on the exterior of the two outer reinforcement plates, and a plurality of inner buffer grooves being disposed on the interior of the two outer reinforcement plates.

[0007] Preferably, the upper end of the reinforcing plate body is provided with two integrally formed openings, and positioning rings are installed inside the two openings, with the two positioning rings being distributed in a mirror symmetrical manner.

[0008] Preferably, the positioning ring has an integrally formed locking hole inside, and a mounting plate is welded to one side of the upper end of the reinforcing plate body, the mounting plate having an integrally formed positioning hole inside.

[0009] Preferably, the mounting plate is embedded inside the front wheel cover and fits into the front wheel cover, and the positioning hole and locking hole are both used to fix the reinforcing plate body and the front wheel cover of the car.

[0010] Preferably, the rear end face of the protrusion is provided with an integrally formed inner groove, which is used to assist in supporting the gap between the main body of the reinforcing plate and the front wheel cover.

[0011] Preferably, the lower end face of the outer reinforcing plate is in contact with the inner wall of the front wheel cover, and the upper end of the outer reinforcing plate is provided with an outer support part. Both the outer support part and the inner buffer groove are used to improve the strength of the inner wall of the front wheel cover.

[0012] Preferably, the buffer strip is embedded in the middle of the two outer reinforcing plates and welded to the two outer reinforcing plates, and the upper end of the buffer strip and the lower end of the protrusion are fixedly connected by bolts.

[0013] Preferably, the lower end of the buffer convex strip is provided with an integrally formed concave ring, and a stretching hole is provided in the middle of the inner concave ring.

[0014] Preferably, the inner walls of the protrusion and the buffer protrusion are provided with flanges, and the stretching hole and the concave ring are integrally formed.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The front wheel arch reinforcement plate of this utility model adopts a combination of two outer reinforcement plates, a protrusion, and a buffer strip to improve the overall strength of the front wheel arch reinforcement plate and achieve the best installation effect. While the outer support on the surface of the outer reinforcement plate provides protection, the inner buffer groove can reduce the overall weight of the outer reinforcement plate, achieving lightweight support and protection. Furthermore, through the combination of the inner concave ring and the inner groove, there is a certain range of buffering capacity when the main body of the reinforcement plate is subjected to compression and impact, reducing the pressure on the front wheel arch and thus improving the pressure resistance of the front wheel arch, which is beneficial for long-term operation.

[0017] 2. In operation, the front wheel cover of this utility model is fixed by the positioning ring and the mounting plate. Before fixing, it can be positioned by the buffer convex strip, which facilitates fixing and installation, supports the front wheel cover, improves the installation effect, facilitates operation, facilitates disassembly, adapts to subsequent maintenance and repair work, and further maintains long-term operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To address the issues of existing front wheel arch reinforcement plates failing to maintain structural strength stability during practical use, and their excessive weight affecting vehicle stability and hindering long-term use, please refer to [the relevant documentation / reference]. Figures 1-4 This embodiment provides the following technical solution:

[0025] This embodiment of a high-strength lightweight front wheel arch reinforcement plate for automobiles includes a reinforcement plate body 1. The reinforcement plate body 1 includes a protrusion 2, two outer reinforcement plates 3, and a buffer strip 4. The front wheel arch reinforcement plate adopts a combination of two outer reinforcement plates 3, a protrusion 2, and a buffer strip 4 to improve the overall strength of the front wheel arch reinforcement plate and achieve the best installation effect. The buffer strip 4 is disposed between the two outer reinforcement plates 3, and the protrusion 2 is disposed at the upper end of the buffer strip 4. Several outer support parts 301 are provided on the outside of the two outer reinforcement plates 3, and several inner buffer grooves 302 are provided inside the two outer reinforcement plates 3. While the outer support parts 301 on the surface of the outer reinforcement plate 3 provide protection, the inner buffer grooves 302 can reduce the overall weight of the outer reinforcement plate 3, thereby achieving lightweight support and protection.

[0026] The lower end face of the outer reinforcing plate 3 is connected to the inner wall of the front wheel cover, and the upper end of the outer reinforcing plate 3 is provided with an outer support part 301. Both the outer support part 301 and the inner buffer groove 302 are used to improve the strength of the inner wall of the front wheel cover. The inner buffer groove 302 can reduce the overall weight of the outer reinforcing plate 3, so as to achieve lightweight support and protection.

[0027] In fact, the lower end of the buffer strip 4 is provided with an integrally formed concave ring 402. The inner middle of the concave ring 402 is provided with a stretching hole 401. The inner walls of the protrusion 2 and the buffer strip 4 are both provided with flanged parts. The stretching hole 401 and the concave ring 402 are integrally formed. Through the combination of the concave ring 402 and the inner groove 201, when the reinforcing plate body 1 is squeezed and impacted, it has a certain range of buffering capacity, reduces the pressure on the front wheel cover, thereby improving the pressure resistance of the front wheel cover, which is beneficial for long-term operation.

[0028] Specifically, the front wheel arch reinforcement plate adopts a combination of two outer reinforcement plates 3, a protrusion 2, and a buffer strip 4 to improve the overall strength of the front wheel arch reinforcement plate and achieve the best installation effect. While the outer support part 301 on the surface of the outer reinforcement plate 3 provides protection, the inner buffer groove 302 can reduce the overall weight of the outer reinforcement plate 3, achieving lightweight support and protection. Furthermore, through the combination of the inner concave ring 402 and the inner groove 201, there is a certain range of buffering capacity when the reinforcement plate body 1 is subjected to compression and impact, reducing the pressure on the front wheel arch and thus improving the pressure resistance of the front wheel arch, which is beneficial for long-term operation.

[0029] To address the issue of existing front wheel arch reinforcement plates having a complex structure that affects long-term use, please refer to... Figures 1-4 This embodiment provides the following technical solution:

[0030] In this embodiment, the upper end of the reinforcing plate body 1 is provided with two integrally formed through-holes 101. Each of the two through-holes 101 is equipped with a positioning ring 102. The two positioning rings 102 are distributed in a mirror symmetrical manner and are locked inside to facilitate installation.

[0031] The positioning ring 102 has an integrally formed locking hole 103 inside. The upper side of the reinforcing plate body 1 is welded to the mounting plate 104. The mounting plate 104 has an integrally formed positioning hole 105 inside. The mounting plate 104 is used for installation and is fixed to the inner wall of the front wheel cover.

[0032] Furthermore, the mounting plate 104 is embedded inside the front wheel cover and fits into it. The positioning hole 105 and the locking hole 103 are both used to fix the reinforcing plate body 1 and the front wheel cover of the car. During operation, the front wheel cover is fixed by the positioning ring 102 and the mounting plate 104.

[0033] It should be noted that the rear end face of the protrusion 2 is provided with an integrally formed inner groove 201. The inner groove 201 is used to assist in supporting the gap between the main body 1 of the reinforcing plate and the front wheel cover. In addition, the buffer protrusion 4 is embedded in the middle of the two outer reinforcing plates 3 and welded to the two outer reinforcing plates 3. The upper end of the buffer protrusion 4 is fixedly connected to the lower end of the protrusion 2 by bolts. The buffer protrusion 4 is used for positioning, which facilitates fixing and installation. While supporting the front wheel cover, it improves the installation effect, facilitates operation, facilitates disassembly, adapts to subsequent maintenance and repair work, and further maintains long-term operation.

[0034] Specifically, during operation, the front wheel cover is fixed by the positioning ring 102 and the mounting plate 104. Before fixing, it can be positioned by the buffer protrusion 4 to facilitate fixing and installation. While supporting the front wheel cover, it improves the installation effect, facilitates operation, and makes it easy to disassemble, adapting to subsequent maintenance and repair work, and further maintaining long-term operation.

[0035] Working principle: During use, the front wheel cover is fixed to the inner wall of the front wheel cover by the positioning ring 102 and the mounting plate 104. Before fixing, it can be positioned by the buffer ridge 4 to facilitate fixing and installation. While supporting the front wheel cover, it improves the installation effect, facilitates operation, and makes it easy to disassemble, adapting to subsequent maintenance and repair work. The front wheel cover reinforcement plate adopts a combination of two outer reinforcement plates 3, a protrusion 2, and a buffer ridge 4 to improve the overall strength of the front wheel cover reinforcement plate to achieve the best installation effect. While the outer support part 301 on the surface of the outer reinforcement plate 3 provides protection, the inner buffer groove 302 can reduce the overall weight of the outer reinforcement plate 3, achieving lightweight support and protection. Furthermore, through the combination of the inner concave ring 402 and the inner groove 201, when the reinforcement plate body 1 is subjected to compression and impact, it has a certain range of buffering capacity, reducing the pressure on the front wheel cover, thereby improving the pressure resistance of the front wheel cover and benefiting long-term operation.
