Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and more specifically, relates to an engine hood structure. Background Technology

[0002] Traditional engine hoods are typically made of metal materials (such as steel or aluminum alloys), which, while offering high strength and heat resistance, are also heavy, hindering lightweight design and consequently impacting fuel economy and emissions performance. As the automotive industry's demand for lightweight construction increases, the use of plastic materials to replace metals has become a trend. However, plastic materials have limitations in strength, heat resistance, and impact resistance, making them difficult to directly replace metals.

[0003] Existing technology includes a design entitled "A Car Engine Cover" with publication number CN107433987A. This technology relates to a car engine cover, comprising a top arc edge, a bottom arc edge, a left arc edge, and a right arc edge. One end of the top arc edge and one end of the bottom arc edge are connected to the upper and lower ends of the left arc edge, respectively. The other ends of the top arc edge and the bottom arc edge are connected to the upper and lower ends of the right arc edge, respectively. The top arc edge, bottom arc edge, left arc edge, and right arc edge together form a cover plate. The cover plate has heat dissipation holes, and a cooling fan is installed within these holes. The cooling fan is connected to a power circuit via a controller. The controller includes a metal casing, an input power line, an output power line, a conductive plate, an insulating post, an insulating platform, a temperature sensing plate, a left conductive post, and a right conductive post. This design not only has high heat dissipation efficiency but also strong controllability.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an engine hood structure that is simple in structure, achieves lightweight design, and has good mechanical properties and heat resistance, in order to overcome the shortcomings of the existing technology.

[0024] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0025] As attached Figure 1 -Appendix Figure 4 As shown, this utility model is an engine hood structure, including an engine hood body 1, which is an engineering plastic layer. The outer surface of the engine hood body 1 is provided with a high-temperature resistant coating 2 and / or an ultraviolet protective layer 3. The inner surface of the engine hood body 1 is provided with reinforcing ribs 4, which include multiple reinforcing ribs 5. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. Instead of using metal materials to make the engine hood, engineering plastics are used. Engineering plastics are lightweight, and with the addition of reinforcing ribs, they have good strength, impact resistance, and weather resistance, effectively meeting the requirements of lightweight design and strength. To improve the strength of the engine hood, reinforcing ribs are provided on the inner surface of the engine hood body. These reinforcing ribs include multiple reinforcing ribs, covering the inner surface of the engine hood body. The multiple reinforcing ribs are arranged in a network pattern, effectively enhancing the strength of the engine hood body from the inside. Simultaneously, the outer surface of the engine hood body 1 is sprayed to form a high-temperature resistant coating 2 and / or an ultraviolet protective layer 3, thereby improving the weather resistance and aesthetics of the engine hood surface. The engine cover structure described in this utility model is simple in structure, achieving both lightweight design and good mechanical properties and heat resistance.

[0026] The engine cover body 1 has multiple reinforcing ribs 5 forming a grid-like or honeycomb-like reinforcing rib section 4. The above structure is shown in the attached diagram. Figure 1 As shown in Embodiment 1, the engine cover body 1 has multiple reinforcing ribs 5 forming a square grid structure, reliably covering the engine cover body 1 and improving its strength. (See attached diagram.) Figure 4 As shown in Embodiment 2, the reinforcing rib 5 of the reinforcing rib 4 can also be a honeycomb structure, which is also used to improve the strength of the engine cover body 1.

[0027] The engine hood body 1 is made of polyamide or polycarbonate material. The material chosen for the engine hood body 1 has good impact resistance and weather resistance.

[0028] A foamed material layer 6 is disposed in the middle of the engine cover body 1. In the above structure, the foamed material layer fills the interior. The foamed material is lighter than the engineering plastic used to house the engine cover, thus reliably reducing the weight of the entire engine cover and improving sound and heat insulation performance. The foamed material layer 6 is an optional component and is not mandatory, allowing for different implementation methods.

[0029] A metal reinforcement 7 is embedded in the engine hood body 1. In this structure, the metal reinforcement 7 is embedded during the molding of the engine hood, thus forming an integral structure with the engine hood body. On the one hand, the metal reinforcement 7 can enhance the strength of the local stress-bearing parts of the engine hood; on the other hand, the connection between the engine hood 1 and the vehicle can be achieved through the connecting hinge. The metal reinforcement 7 is an optional component and is not mandatory, resulting in different implementation methods. When the metal reinforcement 7 is not provided, the connecting hinge 9 is directly injection molded onto the engine hood body 1.

[0030] The engine cover body 1 and the reinforcing rib 4 are integrally molded. The engine cover body 1 and the reinforcing rib 4 are integrally injection molded. This structure simplifies the overall engine cover manufacturing process, and the integral molding of the engine cover body 1 and the reinforcing rib 4 ensures a reliable connection between the two, guaranteeing the strength of the engine cover.

[0031] The metal reinforcement 7 is positioned at the hinge mounting position 8 of the engine hood body 1. A connecting hinge 9 is provided on the metal reinforcement 7. In this structure, the connecting hinge is fixedly connected to the metal reinforcement 7, and the connecting hinge 9 is used to achieve a movable connection between the engine hood and the vehicle body.

[0032] The engine hood structure of this utility model eliminates the use of metal materials. Instead, it is made of engineering plastics through injection molding. Engineering plastics are lightweight, and with the addition of reinforcing ribs 4, they offer high strength, excellent impact resistance, and weather resistance, effectively meeting the requirements for lightweight design and strength. To further enhance the strength of the engine hood, reinforcing ribs 4 are provided on the inner surface of the engine hood body 1. These reinforcing ribs 4 include multiple reinforcing ribs 5, covering the inner surface of the engine hood body 1. The multiple reinforcing ribs 5 are arranged in a network pattern, effectively strengthening the engine hood body 1 from the inside. Simultaneously, the outer surface of the engine hood body 1 is sprayed to form a high-temperature resistant coating 2 and / or a UV protective layer 3, effectively improving the weather resistance and aesthetics of the engine hood surface.

[0033] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
