Commercial vehicle full-surrounding turbulent flow cover

Abstract

The invention discloses a commercial vehicle full-surrounding turbulent flow cover, and the outer surfaces of the top, the left portion and the right portion of the spoiler cover are common surfaces;reinforcing ribs are arranged on the inner surfaces of the top, the left portion and the right portion of the spoiler cover, a plurality of fixed bases are evenly arranged on the inner surfaces of thetop, and the left portion and the right portion of the spoiler cover at intervals in advance, wherein screw holes are formed in the fixed bases in advance. The outer surface or the inner surface of the fixed base is covered with an n-shaped component, and the n-shaped component forms a hollow channel in the two side edges and the middle of the inner surfaces of the top, the left portion and the right portion of the spoiler cover. The top, the left portion, the right portion and the n-shaped component of the turbulent flow cover are made of DCPD materials. Because the DCPD resin is brand-new olefin cross-linked thermosetting resin taking dicyclopentadiene as a main raw material, the DCPD resin is a new material capable of producing large-sized or complex-shaped molded workpieces in an extremely short time. The high-pressure RIM machine is used for pouring the DCPD material, polymerization reaction is carried out in a mold for forming, the method is suitable for large-scale, medium-scale and small-scale wide-range production, and the requirements for energy saving, resource saving and the like are met.

Description

technical field [0001] The invention relates to a peripheral part of a commercial vehicle, in particular to a fully-enclosed spoiler for a commercial vehicle. Background technique [0002] Spoilers play a vital role in the peripheral components of commercial vehicles. At present, the roof spoilers used in commercial vehicles are mainly height-adjustable structures, which are designed to meet the needs of cargo boxes of different heights and reduce the Wind resistance, the purpose of energy saving and emission reduction. However, this height-adjustable structure has the disadvantages that the adjustment mechanism is inconvenient to adjust inside the cab, and the user goes to the roof to adjust and there is a safety risk. [0003] The authorized notification number is CN201633799U, which discloses a heavy-duty vehicle roof spoiler. The design can adjust the height of the top spoiler. The design is complex in structure and heavy in weight, which not only increases the producti...

AI Technical Summary

Problems solved by technology

However, its function is basically the same as that of the above-mentioned heavy-duty car roof spoiler. At the same time, there are defects in the utilization of materials and the lightweight of the product. First, the materials are made of glass fiber reinforced plastic products or injection molding, which is not conducive to environmental protection. Secondly, the weight is relatively heavy. , virtually increases the weight, which is not conducive to lightweight

[0005] In addition, due to the high wind resistance of the car at high speed, in order to prevent the spoiler from deforming, a number of ribs or support frames are added to the inside of the spoiler, which is heavy and adds weight virtually, which is not conducive to lightweight
