Technical Field
[0001] This utility model relates to the field of automotive parts, and in particular to an automotive engine cover assembly. Background Technology
[0002] With the continuous development of the automotive industry, the performance and reliability of the car engine, as a core component, have attracted much attention. The engine cover assembly, as an important part of the engine compartment, plays a key role in many aspects. In automotive design, the engine cover assembly mainly focuses on simple covering and protection functions. Its structure is usually relatively simple, and it is mostly made of ordinary thin metal plates or plastic materials to form a flat structure, which is fixed to the top of the engine compartment by simple buckles or bolts.
[0003] However, traditional automotive engine cooling mainly relies on the engine's built-in cooling system and the convection effect generated by natural wind during vehicle movement. Although the cooling system can remove some heat through the circulation of coolant inside the engine, its ability to dissipate heat from the entire engine compartment is relatively limited. Especially when the vehicle is driven for a long time and the engine is running under continuous high load, heat will accumulate and rise continuously. At this time, the convection effect of natural wind is difficult to expel the rising heat. Furthermore, because the inside of the cover plate is concave, the heat in the engine compartment rises and accumulates inside the engine cover plate, making it difficult to dissipate. This results in poor heat dissipation inside the cover plate. Therefore, an automotive engine cover plate assembly is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides an automotive engine cover assembly, which aims to improve the problem in the prior art that "during long-term driving of a car, the engine operates under high load and generates heat, causing the temperature inside the compartment to rise continuously and move into the inside of the cover, making it difficult to dissipate, resulting in poor heat dissipation inside the cover".
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automobile engine cover assembly, including a cover body, a heat dissipation component is provided at the top of the cover body, the heat dissipation component includes an air inlet frame and an air outlet frame, the air inlet frame passes through and is fixedly connected to the left side of the cover body, a second air guide plate is fixedly connected to the lower right side of the air inlet frame, a wind deflector is fixedly connected to the bottom of the cover body, and a first air guide plate is fixedly connected to both the front and rear surfaces of the wind deflector.
[0006] As a further description of the above technical solution:
[0007] The outer sides of the air inlet frame and the air outlet frame are provided with protective components, the protective components include a protective frame and a second protective plate, and the top of the air outlet frame is fixedly connected to the first protective plate.

[0012] As a further description of the above technical solution:
[0013] The wind deflector is located on the left side of the three sets of air outlet frames, and the left side of the air outlet frames is inclined downwards.
[0014] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, by setting an air inlet frame, air can be transmitted from the air inlet frame into the cover and the engine compartment. After the air enters, it moves horizontally to the right through the second air guide plate, blowing the heat moving upward inside the engine compartment to the right to the wind baffle.

[0022] 2. In this utility model, by setting a protective frame and a second protective plate, leaves can be prevented from entering the cabin from the air inlet frame and the air outlet frame. At the same time, when air blows in from the air inlet frame and exhausts heat from the air outlet frame, the second protective plate can be automatically opened to exhaust the heat. While providing protection, it can also ensure normal heat dissipation and further improve the heat dissipation effect. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of an automobile engine cover assembly, comprising a cover body 1, which is an engine cover. The top of the cover body 1 is provided with a heat dissipation component 2 for convenient heat dissipation. The heat dissipation component 2 includes an air inlet frame 22 for inputting air and an air outlet frame 21 for dissipating heat. The middle part of the air inlet frame 22 is hollow to draw in air, and the interior of the air outlet frame 21 is hollow to dissipate heat. The air inlet frame 22 is connected through and fixedly connected to the left side of the cover body 1. The left side of the air inlet frame 22 is located above the cover body 1, and the right side of the air inlet frame 22 is inclined to the bottom of the cover body 1.
[0032] Furthermore, a second air guide plate 25 is fixedly connected to the lower right side of the air inlet frame 22 to guide the air to the right. The second air guide plate 25 can guide the air so that the air moves horizontally and stably to the right after entering. A baffle plate 23 is fixedly connected to the bottom of the cover 1. When the heat passes through the baffle plate 23, it will be evenly distributed to the three sets of air outlet frames 21, avoiding the heat from being concentrated in one air outlet frame 21 and causing uneven heat dissipation. This improves the stability and reliability of the entire heat dissipation system. The front and rear surfaces of the baffle plate 23 are fixedly connected to the first air guide plate 24. The first air guide plate 24 can optimize the guidance of the heat in the front and rear directions to move to the three sets of air outlet frames 21 in the middle.
[0033] Reference Figure 2 , Figure 4 and Figure 5 The outer sides of the air intake frame 22 and the air outlet frame 21 are provided with protective components 3 to prevent leaves and other debris from entering the engine compartment. The protective components 3 include a protective frame 31 to prevent leaves and other debris from being sucked into the air intake frame 22 during vehicle operation and then into the engine compartment, and a second protective plate 34 to close the air outlet frame 21 in non-heating state to prevent external dust and debris from entering the engine compartment through the air outlet frame 21. The top of the air outlet frame 21 is fixedly connected with a first protective plate 33 to block dust, rainwater and other impurities from entering the air outlet frame 21.
[0034] Reference Figure 1 , Figure 3 and Figure 4 The air outlet frame 21 is connected to the right side of the cover 1. Both sets of air guide plates 24 are inclined, which allows heat to flow more smoothly along the predetermined path and reduces heat loss during the flow. There are three sets of air outlet frames 21, which are evenly arranged on the right side of the cover 1. Setting three sets improves heat dissipation efficiency. The right side of the air inlet frame 22 is inclined downward, which facilitates the input of air into the cabin. The baffle plate 23 is located on the left side of the three sets of air outlet frames 21. The left side of the air outlet frame 21 is inclined downward, which facilitates the intake of heat from the cabin rising to the bottom of the cover 1 and then exhausting it from the right side of the air outlet frame 21.
[0035] Reference Figure 2 , Figure 4 and Figure 5The protective frame 31 is fixedly installed on the left side of the air inlet frame 22 by fastening screws 32. The protective frame 31 can be easily installed by fastening screws 32. At the same time, multiple sets of through holes are opened on the left side and bottom of the protective frame 31 to draw in air and block leaves. The installation by fastening screws 32 can be easily disassembled for maintenance. The front and rear surfaces of the first protective plate 33 are fixedly connected with mounting blocks 35 for supporting the rotating rod 36 and the second protective plate 34. The rotating rod 36 supporting the second protective plate 34 is rotatably connected between the two sets of mounting blocks 35.
[0036] Furthermore, the rotating rod 36 passes through and is fixedly connected to the upper front and rear surfaces of the second protective plate 34. The bottom right side of the first protective plate 33 is set as an inclined surface. By setting it as an inclined surface, the second protective plate 34 can be prevented from rotating too much to the upper right and thus cannot be reset. Therefore, the first protective plate 33 can block the second protective plate 34. Thus, after the second protective plate 34 is automatically opened by the heat, it can automatically reset by rotating downwards under its own gravity when the heat stops blowing.
[0037] Working principle: When the vehicle is in use, outside air enters the air intake frame 22 through multiple sets of through holes on the left and bottom of the protective frame 31. While ensuring smooth air entry, the protective frame 31 can block debris such as leaves. The air flows into the engine compartment at the bottom of the cover 1 along the downward-sloping channel on the right side of the air intake frame 22. Under the action of the air guide plate 25, the air flow direction of the air entering the engine compartment is changed, causing the air to move horizontally to the right. At this time, the heat generated in the engine compartment due to the continuous operation of the engine rises upward. As the air flows to the right, it pushes the heat to the wind deflector 23. The wind deflector 23 evenly distributes the heat to the inlet of the three sets of air outlet frames 21.
[0038] Furthermore, the air guide plates 24 on the front and rear surfaces of the wind deflector 23 are further optimized to guide the heat in the front and rear directions to the three sets of air outlet frames 21 in the middle, ensuring that the heat can be guided to the air outlet frames 21 in a comprehensive and even manner. The downward tilting design of the left side of the air outlet frame 21 allows the heat to be drawn in. The heat and air then flow to the right side of the air outlet frame 21 and push the protective plate 34, causing the protective plate 34 to rotate and open, so that the heat can be discharged to the outside environment. The heat can be discharged without opening the cover 1, thereby realizing the continuous discharge of heat from the engine compartment, effectively reducing the temperature inside the engine compartment and improving the service life of the engine.
[0039] In non-heat dissipation state, the second protective plate 34 is closed under its own weight, covering the right side of the air outlet frame 21 to prevent external dust and debris from entering the engine compartment through the air outlet frame 21. When hot air is discharged from the engine compartment, the airflow pressure generated by the hot air acts on the second protective plate 34, causing it to rotate around the rotating rod 36 and open, allowing the hot air to be discharged from the air outlet frame 21. When the heat stops blowing, the second protective plate 34 rotates downward under its own weight and automatically resets. The inclined surface of the first protective plate 33 can prevent the second protective plate 34 from rotating too much to the upper right and failing to reset, thus ensuring the normal opening and closing function of the second protective plate 34. This achieves automatic opening during heat dissipation and automatic closing during non-heat dissipation, further improving the heat dissipation and protection effects.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
