A fully enclosed spoiler for commercial vehicles

Abstract

This invention relates to a fully enclosed spoiler for commercial vehicles. The outer surfaces of the top, left, and right sides of the spoiler are common surfaces, while the inner surfaces are equipped with reinforcing ribs. Multiple fixing bases are evenly spaced on the inner surfaces of the top, left, and right sides of the spoiler, each with pre-drilled screw holes. Several components are covered on the outer or inner surfaces of the fixing bases, forming hollow channels on both sides and in the middle of the inner surfaces of the top, left, and right sides of the spoiler. The top, left, and right sides of the spoiler and the several components are made of DCPD material. DCPD resin is a novel olefin-based cross-linked thermosetting resin with dicyclopentadiene as the main raw material, a new material capable of producing large or complex-shaped molded parts in a very short time. DCPD material is cast using a high-pressure RIM machine, where it undergoes a polymerization reaction in a mold to form the desired shape. This method is suitable for a wide range of production volumes, from large to medium to small, meeting requirements for energy conservation and resource saving.

Description

Technical Field

[0001] The invention relates to a peripheral component of a commercial vehicle, in particular to a fully enclosed spoiler cover for a commercial vehicle. Background Art

[0002] Spoilers play a crucial role in commercial vehicle exterior components. Currently, roof spoilers used on commercial vehicles are primarily height-adjustable. Their purpose is to accommodate cargo box heights of varying sizes, thereby reducing wind resistance and achieving energy savings and emissions reductions. However, this height-adjustable structure suffers from the inconvenience of adjusting the mechanism inside the cab, and the safety risks of requiring users to adjust the spoiler from the roof.

[0003] Authorization announcement number CN201633799U discloses a roof spoiler for a heavy-duty vehicle. This design allows for adjustable height of the roof spoiler. However, this design is complex and heavy, increasing both manufacturing costs and fuel consumption. Furthermore, this design only restricts the roof of the heavy-duty vehicle, while still disrupting airflow around the sides of the cab, creating drag.

[0004] Application No. 201811498021.5 provides a fixed roof spoiler system. While this design offers reduced safety risks and low application costs, it performs essentially the same function as the aforementioned heavy-duty vehicle roof spoilers and suffers from drawbacks in material utilization and product lightweighting. First, the materials used are fiberglass or injection molded, which is not environmentally friendly. Second, the heavy weight inadvertently increases weight, hindering lightweighting.

[0005] Furthermore, since the wind resistance of a car is relatively large when it is driving at high speed, in order to prevent the spoiler from deforming, a number of reinforcing ribs or support frames are added to the inside of the spoiler, which are heavy and invisibly increase the weight, which is not conducive to lightweighting. Summary of the Invention

[0006] The present invention provides a fully enclosed spoiler for a commercial vehicle for the purpose of environmental protection and lightweighting, as well as for all-round reduction of the vehicle's wind resistance.

[0007] To this end, the technical solution of the present invention is a fully enclosed spoiler for commercial vehicles, wherein the spoiler is divided into three parts: the top, left and right parts of the spoiler, wherein the outer surfaces of the top, left and right parts of the spoiler are common surfaces, and a plurality of reinforcing ribs are provided on the inner surfaces. The characteristics are as follows: a plurality of fixing bases are preset at even intervals on both sides of the inner surfaces of the top, left and right parts of the spoiler, wherein screw holes are preset on the fixing bases; and a "several" component is covered on the inner surface outside the fixing base, wherein the "several" components form a hollow channel on the inner surface of the top, left and right parts of the spoiler.

[0008] The "several" components form hollow channels on both sides and in the middle of the inner surfaces of the top, left and right parts of the spoiler.

[0009] The "several" components are bonded or welded to the top, left and right inner surfaces of the spoiler on both sides and in the middle, and the hollow channel and a plurality of fixed bases are fixed to form strengthening ribs.

[0010] The fixed base is further provided with a connecting support outwardly, and the connecting support is connected and fixed to the vehicle body.

[0011] The top, left part, right part, fixed base and "several" parts of the spoiler are made of DCPD material.

[0012] Beneficial effects:

[0013] The spoiler of the present invention is divided into three parts: the top, the left part, and the right part, which are manufactured separately, reducing the difficulty of mold manufacturing and the tonnage of the equipment. The inner surface is provided with reinforcing ribs which are injected together during the injection molding process to increase the surface strength. The arrangement of multiple fixing seats and the covering of the inner surface with "several" parts facilitate installation. The "several" parts form a hollow channel on the inner surface of the spoiler, thereby reducing the weight of the spoiler.

[0014] The principle of greater strength and supporting force of the hollow channel is used to replace the original support frame, thereby achieving the purpose of weight reduction and convenient manufacturing.

[0015] The hollow channel and the multiple bases form reinforcing ribs on the inner surface of the spoiler, which have good strength and light weight and support the spoiler without deformation when the vehicle moves forward.

[0016] The spoiler and the "ji" components are made of DCPD because DCPD resin, a new olefin-based cross-linked thermosetting resin primarily made from dicyclopentadiene, is a novel material capable of producing large or complex workpieces in a very short time. Using a high-pressure RIM machine to cast the DCPD material, a polymerization reaction occurs in the mold, resulting in a wide range of production, from large to medium to small quantities, while meeting contemporary demands for energy conservation and resource conservation.

[0017] Features:

[0018] 1. Wide molding range: Because it is a low-viscosity liquid resin, it can produce large, complex-shaped, and thick-walled workpieces.

[0019] 2. Good balance of physical properties: taking into account both impact resistance and rigidity, it is most suitable for making surface decorations and structural work.

[0020] 3. Excellent low-temperature characteristics: suitable for making workpieces for use in low-temperature environments.

[0021] 4. Good drug resistance: It has excellent corrosion resistance, especially acid and alkali resistance.

[0022] 5. Excellent coating properties. After molding, an oxide film is formed on the surface, which has good adhesion to the paint.

[0023] 6. Short molding cycle.

[0024] 7. Environmentally friendly.

[0025] Application areas: Mainly used in automobiles, agricultural vehicles, and construction machinery: Reducing part weight, reducing air resistance, and integrating parts are the trends in future truck and automobile manufacturing. DCPD process products provide manufacturers with a good solution.

[0026] The commercial vehicle full-surround spoiler made of this material is 48% lighter than the original product. Although the strength of a single DCPD piece is insufficient, the strength is also improved by using hollow channels and multiple bases to form reinforcement ribs. BRIEF DESCRIPTION OF THE DRAWINGS
