Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a single-plate widened side fairing structure. Background Technology

[0002] To minimize wind resistance and achieve fuel and energy savings, the width of the side fairing needs to be as close as possible to the trailer body. This means widening the existing narrow side fairing. However, current industry side fairings are all made of plastic. Widening the side fairing would significantly reduce structural stiffness, resulting in excessive modal analysis disturbances. This would lead to visible axial vibrations and tearing at the vehicle's fixed points during driving. Due to this industry challenge, current widened side fairings both domestically and internationally employ a double-plate structure with glued inner and outer panels. While this double-plate structure addresses insufficient stiffness and modal non-compliance with technical specifications, it also introduces problems such as high investment in molds and production equipment, high unit cost, complex adhesive bonding processes, and heavy component weight. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a single-plate widened side fairing structure.

[0004] This utility model is achieved using the following technical solution:

[0005] A single-plate widened side fairing structure, wherein the side fairing is a single-plate structure, and a plurality of boss structures are provided on the inner side of the single-plate structure, and the single-plate structure and the boss structures are integrally formed.

[0006] Preferably, the side fairing is made of plastic.

[0007] Preferably, the boss structure and the base plane of the single-plate structure are circularly transitioned.

[0008] Preferably, the boss structure has rounded corners on both sides.

[0009] Preferably, the radius of the arc and the radius of the fillet are the same.

[0010] Preferably, the outermost boss structure is located near the edge of the single-plate structure.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] 1. This utility model replaces the existing widened side fairing made of plastic single sheet, which solves the problem that the stiffness and modal characteristics of the existing technology do not meet the design specifications, and avoids the risk of obvious circumferential vibration and possible tearing of the vehicle body during vehicle driving.

[0013] 2. This utility model replaces the existing plastic adhesive double-plate widened side guide cover, solving the problems of large investment in molds and production equipment, high unit cost, complex adhesive bonding process, and heavy weight of parts caused by the existing technology; it significantly reduces costs, reduces process difficulty, significantly increases production capacity, and reduces weight, thereby minimizing wind resistance and achieving fuel and electricity savings.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise explicitly specified and limited, the embodiments and features described in the embodiments of this application can be combined with each other. In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1-3 As shown: A single-plate widened side fairing structure, wherein the side fairing is a single-plate structure 1, and a plurality of boss structures 2 are provided on the inner side of the single-plate structure 1, and the single-plate structure 1 and the boss structures 2 are integrally formed.

[0020] The side fairings are made of plastic. The overall width of the side fairings is greater than 600mm, and the thickness of the single-plate structure 1 is D1 = 5.0mm.

[0021] The boss structure 2 and the single-plate structure 1 have a rounded transition at their base planes. Furthermore, the boss structure 2 has rounded corners on both sides. Even further, the radii of the rounded corners and the rounded corners are the same. Preferably, the radii of the rounded corners and the rounded corners are R = 50mm. That is, the boss structure 2 and the single-plate structure 1 use a large rounded transition; the boss structure 2 replaces the fixing bracket in the existing adhesive structure, with a width of 45mm and a thickness of 0.5mm, and the overall thickness of the single-plate structure 1 and the boss structure 2 is D2 = 5.5mm.

[0022] The outermost boss structure 2 is close to the edge of the single-plate structure 1. Preferably, the outermost boss structure 2 is 25-30 mm away from the edge of the single-plate structure 1.

[0023] The widened side fairing made of plastic veneer meets the rigidity and modal technical requirements after CAE software analysis. At the same time, the overall structure is as close as possible to the trailer body, which reduces wind resistance, saves fuel and electricity, significantly reduces costs and labor time, reduces the difficulty of production process, significantly increases production capacity, and also reduces the weight.
