[0002] An engine hood is a cover-like component that covers the engine, usually made of metal or nylon plastic. It serves to protect the engine, reduce noise, and make the engine compartment look neat and aesthetically pleasing, making it an essential part of every car. However, existing nylon engine hoods with good sound absorption have certain problems in use and still require continuous improvement.

[0003] A search revealed an existing patent (publication number: CN218343609U) disclosing an automobile engine hood cover, including a cover plate. A locking part is installed at the top of the cover plate, and a fixing mechanism is installed on the cover plate. The fixing mechanism includes: several mounting slots, several pins, several pressing and actuating plates, an elastic structure, and a sound-absorbing structure. Several mounting slots are respectively formed on the cover plate, and several pins are rotatably mounted at several mounting slots. Several pressing and actuating plates are fitted onto several pins. By incorporating sound-absorbing cotton and protrusions, noise generated during engine operation is easily absorbed. Part of the sound is absorbed by the sound-absorbing cotton, and the other part is reflected and absorbed by the protrusions. Simultaneously, the springs, pressing and actuating plates, and pins facilitate the installation of the sound-absorbing cotton. In rainy weather, the sound-absorbing cotton absorbs water, thus achieving a moisture-proof effect on the engine. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] The existing device uses sound-absorbing cotton to absorb water during use. However, sound-absorbing cotton is prone to absorbing water in hot and humid environments, which can lead to mold, rot or deformation, thus affecting the effectiveness of the sound-absorbing cotton and reducing its service life.

[0005] Therefore, a nylon engine cover with good sound absorption is proposed to address the above problems. Summary of the Invention

Each of the plurality of supporting and limiting blocks has a groove at the beginning, and the groove has a triangular cross-section. Sound-absorbing cotton is arranged inside the cover shell, and the plurality of color-changing silicone strips are in contact with and connected to the sound-absorbing cotton. A fixing component is provided on the inner sidewall of the cover shell for limiting and fixing the sound-absorbing cotton.

[0008] Preferably, the sound-absorbing cotton has several protrusions fixedly arranged at equal intervals on its surface, and each of the protrusions has a cavity.

[0009] Preferably, the fixing component includes a rotating block, a pressing block, and a torsion spring. The inner sidewall of the cover plate housing is provided with a mounting groove, and a pin is fixedly installed in the mounting groove. A limiting block is fixedly installed at both ends of the outer side of the pin. A rotating block is rotatably sleeved on the outer side of the pin and located between the two limiting blocks. A pressing block is fixedly welded to the outer side of the rotating block. A torsion spring is provided on the outer side of the pin and located on both sides of the rotating block.

[0010] Preferably, a limiting groove is formed at the edge of one side surface of the cover plate housing, and a sealing strip is provided in the limiting groove to increase the sealing performance when the cover plate housing is closed.

[0021] 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. Example 1

[0022] As attached Figures 1 to 4 The nylon engine cover with good sound absorption is shown. It includes a plurality of support limiting blocks 16 fixedly arranged at equal intervals on the bottom surface of the cover shell 1. A color-changing silicone strip 17 is arranged between every two support limiting blocks 16. The color-changing silicone strip 17 will change color after absorbing a certain amount of water. The amount of water absorbed by the color-changing silicone strip 17 can be judged by the color change, so that the color-changing silicone strip 17 can be replaced. The color-changing silicone strip 17 can be reused after drying. Each of the support limiting blocks 16 has a groove 15 with a triangular cross-section to reduce the overall weight of the device. Sound-absorbing cotton 4 is arranged inside the cover shell 1. The plurality of color-changing silicone strips 17 are in contact with the sound-absorbing cotton 4. A fixing component is provided on the inner side wall of the cover shell 1 to limit and fix the sound-absorbing cotton 4.

[0023] The cover shell 1 is made of nylon fiber material, which has good toughness, making the device more durable and wear-resistant. The added color-changing silicone strip 17 has good water absorption capacity. The contact between the color-changing silicone strip 17 and the sound-absorbing cotton 4 can absorb the moisture on the sound-absorbing cotton 4, preventing the sound-absorbing cotton 4 from being in a high-temperature and humid environment for a long time, which would lead to mold, rot or deformation. At the same time, it can improve the performance and service life of the sound-absorbing cotton. Furthermore, the addition of the support limit block 16 can stably support and place the color-changing silicone strip 17 between the two support limit blocks 16, improving the practicality of the device. Example 2

[0024] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0025] In a preferred embodiment, a plurality of protrusions 5 are fixedly arranged at equal intervals on the surface of the sound-absorbing cotton 4, and a cavity is provided in each of the plurality of protrusions 5.

[0026] In a preferred embodiment, the fixing assembly includes a rotating block 9, a pressing block 10, and a torsion spring 11. First, a mounting groove 6 is formed on the inner side wall of the cover shell 1. Then, a pin 7 is fixedly installed in the mounting groove 6. Next, a limiting block 8 is fixedly installed at both ends of the outer side of the pin 7. The rotating block 9 is rotatably sleeved on the outer side of the pin 7 and located between the two limiting blocks 8. Then, the pressing block 10 is fixedly welded to the outer side of the rotating block 9. Finally, a torsion spring 11 is installed on the outer side of the pin 7 and on both sides of the rotating block 9. Furthermore, the torsion spring 11 installed on the outer side of the pin 7 can squeeze the pressing block 10, thereby pressing the pressing block 10 tightly against the surface of the edge of the sound-absorbing cotton 4, thus completing the limiting and fixing of the sound-absorbing cotton 4. This allows the sound-absorbing cotton 4 to be stably connected and installed in the cover shell 1, and at the same time, it is convenient to disassemble the sound-absorbing cotton 4, so that the dust attached to the surface of the sound-absorbing cotton 4 can be cleaned regularly, thereby improving the sound-absorbing cotton 4's noise reduction effect.

[0027] In a preferred embodiment, a limiting groove 2 is provided at the edge of one side surface of the cover plate housing 1, and a sealing strip 3 is provided in the limiting groove 2 to increase the sealing performance when the cover plate housing 1 is closed.

[0028] In a preferred embodiment, two connecting blocks 12 are integrally cast on both sides of the outer side wall of the cover plate housing 1. Each of the two connecting blocks 12 has a threaded connection hole 13 that can be screwed into the surface of the connecting block 12. Furthermore, the cover plate housing 1 can be fixedly installed by passing the screw through the threaded connection hole 13 on the surface of the connecting block 12.

[0029] In a preferred embodiment, the surface of the cover shell 1 is coated with a layer of titanium metal color adhesive 14 to increase the sun protection capability of the cover shell 1; furthermore, the titanium metal color adhesive 14 coated on the surface of the cover shell 1 can efficiently reflect ultraviolet rays, thereby improving the sun protection capability and service life of the cover shell 1.

[0030] The working process of this utility model is as follows: First, the torsion spring 11 set on the outside of the pin 7 can squeeze the pressing block 10, thereby pressing the pressing block 10 tightly on the surface of the edge of the sound-absorbing cotton 4, thus completing the limiting and fixing of the sound-absorbing cotton 4, so that the sound-absorbing cotton 4 can be stably connected and set in the cover shell 1, and at the same time, the sound-absorbing cotton 4 can be easily disassembled, so that the dust attached to the surface of the sound-absorbing cotton 4 can be cleaned regularly, improving the sound-absorbing cotton 4's noise reduction effect. Then, the cover shell 1 can be fixedly installed by passing screws through the threaded connection hole 13 opened on the surface of the connecting block 12.

[0031] Meanwhile, the added color-changing silicone strip 17 has good water absorption capacity. Through the contact setting between the color-changing silicone strip 17 and the sound-absorbing cotton 4, the moisture on the sound-absorbing cotton 4 can be absorbed, avoiding the sound-absorbing cotton 4 being in a high temperature and humid environment for a long time, which would lead to mold, rot or deformation. At the same time, it can improve the service life of the sound-absorbing cotton. Furthermore, by adding the support limiting block 16, the color-changing silicone strip 17 set between the two support limiting blocks 16 can be stably supported and placed, improving the practicality of the device. The above is the working principle of this nylon engine cover with good sound absorption.
