Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive cover technology, specifically to an anti-deformation automotive cover. Background Technology
[0002] In modern automobile manufacturing, vehicle covers (such as hoods, roof covers, and trunk lids) are important body components, bearing the responsibility of protecting the engine, air conditioning system, electrical equipment, and the safety of passengers. To improve the overall performance and aesthetics of the vehicle, covers are typically made of lightweight materials such as aluminum alloys, high-strength steel plates, or composite materials to ensure vehicle safety and fuel economy.
[0003] However, as vehicles age, existing car covers are prone to deformation upon reuse, posing potential risks to the vehicle's appearance, function, and structural safety. This problem is mainly related to the following factors:
[0004] Material fatigue: After prolonged exposure to environmental factors such as external pressure, temperature changes, and ultraviolet radiation, automotive hood panels exhibit varying degrees of fatigue and aging, leading to a reduction in their strength and rigidity. This is especially true in areas where components are frequently opened and closed, where the hood is more prone to deformation due to repeated stress.
[0005] Thermal expansion and cooling contraction: During vehicle operation, the cover surface is affected by the engine's heat source, and temperature changes cause the cover material to expand and contract. Under drastic temperature fluctuations, the cover's shape may undergo slight changes, especially for covers made of lighter or thinner materials.
[0006] External impacts and collisions: During vehicle operation, external impacts such as collisions with the chassis or other vehicles, or impacts from stones, can also cause localized deformation of the cover plate. The design and material selection of the cover plate may not have fully considered its resistance to these impacts, especially in complex driving environments, making it prone to localized damage or deformation.
[0007] Manufacturing deficiencies: If the manufacturing process is not refined enough or the materials are not processed evenly, the cover plate may have insufficient local strength and be easily deformed by external pressure. For example, stress concentration may occur in areas such as welded parts and bending angles of the cover plate, leading to deformation.
[0008] Impact of the usage environment: Long-term exposure to harsh environments, such as high temperature, high humidity, and strong ultraviolet radiation, may cause oxidation and corrosion on the surface of the car cover, resulting in surface damage and further affecting the structural integrity and deformation resistance of the cover.
[0009] No solutions have yet been proposed for the relevant technical issues. Utility Model Content
[0010] To address the problems in related technologies, this utility model proposes a deformation-resistant car cover to overcome the aforementioned technical issues in existing technologies. The purpose of this utility model is to effectively resist external impacts and collisions, reduce vehicle body deformation, prevent premature aging or damage of the cover due to fatigue, thermal expansion, or cooling contraction, thereby extending the service life of the entire vehicle, helping to reduce vehicle weight, improve fuel efficiency, reduce carbon dioxide emissions, avoid appearance problems caused by cover deformation, maintain the flatness and aesthetics of the vehicle body lines, reduce the frequency of cover maintenance during long-term use, reduce maintenance costs for car owners, and reduce the frequency of replacement of automotive parts.
[0011] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant car cover plate, comprising a cover plate, with clamping plates fixedly connected to both ends of one side of the cover plate, mounting bolts provided on the clamping plates, a plurality of grooves formed on the cover plate, the grooves extending through the length of the cover plate, a plurality of mounting holes and mounting bolts provided on the grooves, reinforcing protrusions on both sides of the grooves, a plurality of through holes formed on the cover plate, and a plurality of reinforcing ribs installed on the cover plate.
[0012] Preferably, the through hole includes an oblong hole one, an oblong hole two, and an oblong hole three, wherein the length of the oblong hole two is greater than the length of the oblong hole one, and the length of the oblong hole three is greater than the length of the oblong hole two.
[0013] Preferably, the thickness of the cover plate is ≥3.2mm.
[0014] Preferably, the card plate, reinforcing protrusion, and reinforcing rib are all integrated with the cover plate.
[0015] Preferably, the cover plate, the retaining plate, and the reinforcing protrusion are all made of lightweight, high-strength materials.
[0016] Preferably, the outer surfaces of the cover plate, the retaining plate, and the reinforcing protrusion are all coated with an anti-corrosion layer.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] (1) This utility model is a car cover plate that is resistant to deformation. By setting a card plate, mounting bolt one, groove, mounting hole one and mounting hole two, the cover plate can be easily installed in the required position. The installation and disassembly are convenient. The through holes on the cover plate can reduce the weight of the car body, thereby improving fuel efficiency and the handling performance of the whole vehicle. When the car engine is working, it generates a lot of heat. The through holes on the cover plate help guide the air flow and promote the heat dissipation of the cover plate and engine area. It can maintain the rigidity of the car body without sacrificing the structural strength. The through hole design on the cover plate helps to improve air flow, reduce wind resistance and improve the aerodynamic performance of the vehicle.
[0019] (2) This utility model is a car cover plate that is resistant to deformation. By setting reinforcing protrusions and reinforcing ribs on the cover plate, the overall rigidity and anti-deformation ability of the cover plate can be effectively improved. The reinforcing protrusions and reinforcing ribs help to disperse and absorb impact force, reduce local deformation, improve the safety of the vehicle body in accidents, and protect important internal components of the vehicle. The reinforcing protrusions and reinforcing ribs help to promote air circulation and heat dissipation, which can help air flow better in the engine compartment, thereby improving heat dissipation efficiency and helping the vehicle maintain a stable engine temperature under long-term driving or high load conditions.
