Description

Technical Field

[0001] This utility model relates to the field of engine sealing technology, and in particular to cylinder head gasket sealing structures, engines, and vehicles. Background Technology

[0002] Internal combustion engine combustion chambers produce high-temperature, high-pressure combustion gases reaching up to 1000℃ during fuel combustion. A reliable sealing structure is essential between the cylinder head and cylinder block to prevent gas leakage, thus maintaining the engine's power, performance, and reliability. The cylinder head gasket, installed between the cylinder block and cylinder head, primarily functions as a seal, providing a certain sealing pressure to the combustion chamber's gas passage and ensuring an effective seal between the cylinder block and cylinder head. To improve the gasket's heat resistance, current technology typically uses metal gaskets with raised ribs for sealing. However, these metal gaskets are still susceptible to corrosion from the combustion gases, and prolonged use can lead to gasket delamination and subsequent leaks.

[0003] Therefore, a cylinder head gasket sealing structure, engine, and vehicle are needed to solve the above problems. Utility Model Content

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] like Figures 1 to 3 As shown, this embodiment provides a cylinder head gasket sealing structure 1, which is sealed in a sealing groove formed between the cylinder block 2, the cylinder liner 3, the carbon scraper ring 4, and the cylinder head 5. The cylinder head gasket sealing structure 1 includes a cylinder head gasket body 10 and a shielding part 20. The cylinder head gasket body 10 has an annular structure, and the shielding part 20 has an annular structure. The shielding part 20 is connected to the inner circumference of the cylinder head gasket body 10. Part of the shielding part 20 elastically abuts against the cylinder head 5, and part of the shielding part 20 elastically abuts against the carbon scraper ring 4, the cylinder liner 3, or the cylinder block 2. Specifically, in this embodiment, the cylinder head gasket body 10 has an annular structure, and the shielding part 20 has an annular structure. The shielding part 20 is disposed on the inner circumference of the cylinder head gasket body 10, thereby ensuring the normal discharge of combustion gases. Part of the shielding part 20 elastically abuts against the cylinder head 5, and part of the shielding part 20 elastically abuts against the carbon scraper ring 4, so that the shielding part 20 can be radially closer to the gas passage relative to the cylinder head gasket body 10. This allows the shielding part 20 to shield the cylinder head gasket body 10, effectively preventing the high-temperature combustion gases in the gas passage from directly contacting the cylinder head gasket body 10, thereby effectively preventing the cylinder head gasket body 10 from failing due to high temperature. This ensures that the cylinder head gasket body 10 always has good elasticity, ensuring the sealing effectiveness of the cylinder head gasket sealing structure 1, improving safety during use, and extending the service life of the cylinder head gasket sealing structure 1.

[0038] Alternatively, the cylinder gasket sealing structure 1 in this embodiment can be obtained by modifying the existing cylinder gasket sealing structure, so as not to affect the original cylinder port sealing method, and not to affect the specific arrangement of the carbon scraper ring 4. The improvement cost is low and the sealing effect is good.

[0039] Alternatively, in another embodiment, the shielding part 20 can be elastically abutted against the cylinder liner 3 or the cylinder block 2 according to the actual arrangement of the engine, and has the same technical effect, without being specifically limited here.

[0040] Furthermore, such as Figure 3 As shown, the shielding part 20 includes a first abutting part 21, a second abutting part 22, and a connecting part 23. The first abutting part 21 is connected to the cylinder head gasket body 10, and the connecting part 23 is connected between the second abutting part 22 and the first abutting part 21. One of the first abutting part 21 and the second abutting part 22 is used to elastically abut against the cylinder head 5, and the other of the first abutting part 21 and the second abutting part 22 is used to elastically abut against the carbon scraper ring 4, the cylinder liner 3, or the cylinder block 2. Specifically, in this embodiment, the first abutting part 21 is connected to the cylinder head body, which can ensure the integrity of the cylinder gasket sealing structure 1 itself and improve the convenience of the installation process; the connecting part 23 is connected between the second abutting part 22 and the first abutting part 21, so that there is a certain elastic force between the first abutting part 21 and the second abutting part 22, thereby enabling the first abutting part 21 to have good abutting performance when it elastically abuts against the cylinder head 5 and the second abutting part 22 to abut against the carbon scraper ring 4, avoiding damage to the cylinder head 5 and the carbon scraper ring 4.

[0041] Alternatively, in this embodiment, the shielding part 20 is made of a material with good temperature resistance, such as GH4169, and the shielding part 20 has a small elastic force, so the pressure it bears is much less than the pressure of the cylinder head gasket body 10. This can effectively prevent the sealing pressure of the cylinder head gasket body 10 from decreasing, improve the sealing performance, and also ensure that the second contact part 22 can always make good contact with the carbon scraping ring 4 during the carbon removal process of the carbon scraping ring 4 moving up and down, thus avoiding wear on the carbon scraping ring 4.

[0042] Alternatively, in another embodiment, the cylinder head gasket sealing structure 1 can be inverted, such that the first abutting part 21 of the shielding part 20 abuts against the carbon scraper ring 4 and the second abutting part 22 abuts against the cylinder head 5, which can also achieve the same technical effect, and is not limited here.

[0043] Furthermore, such as Figure 3As shown, the first abutting part 21 and the second abutting part 22 are arranged in parallel, and both the first abutting part 21 and the second abutting part 22 are arranged at an angle to the connecting part 23, so that the shielding part 20 has a "Z" shaped structure. Specifically, in this embodiment, setting the shielding part 20 to a "Z" shaped structure can ensure the deformation capability between the first abutting part 21 and the second abutting part 22, thereby improving safety during use, avoiding collisions during installation, and ensuring the contact area between the first abutting part 21 and the cylinder head gasket, while ensuring the contact area between the second abutting part 22 and the carbon scraper ring 4, thereby ensuring the shielding effect of the shielding part 20 on the cylinder head gasket body 10, ensuring that the cylinder head gasket body 10 is not corroded by high-temperature combustion gases.

[0044] Furthermore, such as Figure 3 As shown, the diameter of the inner circumferential surface of the cylinder head gasket body 10 is A, and the maximum diameter of the connection between the second abutment portion 22 and the connecting portion 23 is B, where A > B. Specifically, in this embodiment, this arrangement ensures that the cylinder head gasket body 10 will not compress the blocking portion 20 during actual use, thereby ensuring the blocking effect of the blocking portion 20.

[0045] Furthermore, the thickness of the first abutting portion 21 and / or the second abutting portion 22 and / or the connecting portion 23 ranges from 0.2 to 0.3 mm. Specifically, in this embodiment, the first abutting portion 21, the second abutting portion 22, and the connecting portion 23 have the same thickness, and the thickness ranges from 0.2 to 0.3 mm, which ensures that the shielding portion 20 has good deformation capability, thereby ensuring a good shielding effect.

[0046] Furthermore, such as Figure 3 As shown, the cylinder head gasket body 10 includes a first plate 11, a second plate 12, and sealing portions 13. The first plate 11 and the second plate 12 are spaced apart to form a receiving cavity 14. A plurality of sealing portions 13 are radially spaced in the receiving cavity 14 along the cylinder head gasket sealing structure 1, and a shielding portion 20 is connected to the first plate 11 and / or the second plate 12. Specifically, in this embodiment, the first plate 11 and the second plate 12 form the receiving cavity 14, and the sealing portions 13 are disposed in the receiving cavity 14, which can ensure the sealing effect of the cylinder head gasket body 10. When at least two sealing portions 13 are provided, the two sealing portions 13 are radially spaced along the cylinder head gasket sealing structure 1, thereby ensuring the sealing effect of the cylinder head gasket body 10.

[0047] Specifically, the number of sealing parts 13 provided on the cylinder head gasket body 10 can be specifically set according to actual use, and there is no limitation on whether two adjacent sealing parts 13 are connected or disconnected.

[0048] Alternatively, in this embodiment, the sealing part 13 is connected to both the first plate 11 and the second plate 12 by welding, which can ensure the sealing performance of the sealing part 13 and extend its service life.

[0049] Furthermore, such as Figure 3 As shown, the sealing part 13 includes a first sealing plate 131 and a second sealing plate 132 connected to each other. The first sealing plate 131 is provided with a first elastic part 1311, and the second sealing plate 132 is provided with a second elastic part 1321. The first elastic part 1311 and the second elastic part 1321 are arranged opposite to each other, and the side of the first elastic part 1311 away from the second elastic part 1321 abuts against the first plate 11, and the side of the second elastic part 1321 away from the first elastic part 1311 abuts against the second plate 12. Specifically, in this embodiment, this arrangement can ensure the sealing performance of the sealing part 13, and the number of first elastic parts 1311 on the first sealing plate 131 and the number of second elastic parts 1321 on the second sealing plate 132 can be specifically set according to actual use, and no limitation is made here.

[0050] Furthermore, such as Figure 3 As shown, the first plate 11 includes an end plate 111, an abutment plate 112, and a connecting plate 113. The end plate 111 and the abutment plate 112 are parallel to and spaced apart from the second plate 12. The connecting plate 113 is connected between the end plate 111 and the abutment plate 112. The end plate 111, the abutment plate 112, the connecting plate 113, and the second plate 12 form a receiving cavity 14. The shielding part 20 is sandwiched between the second plate 12 and the abutment plate 112. Specifically, in this embodiment, the end plate 111, the abutment plate 112, the connecting plate 113, and the second plate 12 form a receiving cavity 14, and the connecting plate 113 is connected between the abutment plate 112 and the end plate 111, thereby improving the structural strength of the cylinder sealing structure and ensuring the installation space of the sealing part 13. The shielding part 20 sandwiched between the second plate 12 and the abutment plate 112 can ensure the connection stability of the shielding part 20.

[0051] Specifically, in this embodiment, the end of the first abutting part 21 that is away from the connecting part 23 is sandwiched between the second plate 12 and the abutting plate 112, which can ensure the connection stability of the shielding part 20.

[0052] Specifically, in this embodiment, when the cylinder sealing structure is not in use, the first abutting part 21 and the second abutting part 22 are both parallel to the first plate 11. When the cylinder sealing structure is installed into the sealing groove, the first abutting part 21 and the second abutting part 22 are tilted under pressure, and then abut against the cylinder body 2 and the carbon scraper ring 4 respectively, to ensure sealing performance and service life.

[0053] Furthermore, the inclined setting of the connecting plate 113 can further enhance the structural strength of the cylinder sealing structure, thereby extending its service life.

[0054] Optionally, the first plate 11, the second plate 12, the first sealing plate 131, and the second sealing plate 132 are all made of 301 stainless steel, but are not limited thereto.

[0055] Furthermore, the second plate 12 is welded to the shielding part 20; and / or, the abutment plate 112 is welded to the shielding part 20. Specifically, in this embodiment, both the second plate 12 and the abutment plate 112 are connected to the shielding part 20 by welding, which can improve installation stability, thereby improving performance and extending service life.

[0056] like Figures 1 to 2 As shown, this embodiment also provides an engine, which includes a cylinder block 2, a cylinder liner 3, a carbon scraper ring 4, a cylinder head 5, and the aforementioned cylinder head gasket sealing structure 1. The cylinder liner 3 is coaxially disposed within the cylinder bore of the cylinder block 2, and the carbon scraper ring 4 is coaxially disposed within the center hole of the cylinder liner 3. The cylinder block 2, cylinder liner 3, and carbon scraper ring 4 are all spaced apart from the cylinder head 5, forming a sealing groove. The cylinder head gasket sealing structure 1 is sealed within the sealing groove, and a shielding part 20 is sandwiched between one of the carbon scraper ring 4, the cylinder liner 3, or the cylinder block 2 and the cylinder head 5. This engine, by incorporating the aforementioned cylinder head gasket sealing structure 1, allows the shielding part 20 to shield the high-temperature combustion gases, preventing the cylinder head gasket body 10 of the cylinder head gasket sealing structure 1 from prolonged direct contact with the high-temperature combustion gases, thereby effectively extending the service life of the cylinder head gasket body 10 and ultimately improving the engine's service life.

[0057] Specifically, in this embodiment, as Figure 2 As shown, the first abutting part 21 of the shielding part 20 abuts against the cylinder head 5, and the second abutting part 22 abuts against the carbon scraper ring 4, thereby shielding the cylinder head gasket body 10, effectively preventing the cylinder head gasket body 10 from being corroded by high-temperature combustion gases, thus ensuring the sealing performance of the cylinder head gasket sealing structure 1 and effectively extending its service life.

[0058] In another embodiment, the second abutment portion 22 may abut against either the cylinder block 2 or the cylinder liner 3, depending on the specific arrangement of the engine, without limitation.

[0059] This embodiment also provides a vehicle that includes the aforementioned engine. By incorporating the aforementioned engine, the vehicle can ensure the sealing performance of the engine itself and effectively extend the engine's service life.
