[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] Reference below Figure 1-Figure 4 A sealing assembly 100 according to an embodiment of the present invention is described.

[0034] Reference Figure 1-Figure 3 The sealing assembly 100 of the first embodiment of the novel invention comprises a first component 1, a second component 2 and a sealing member 4. The second component 2 and the first component 1 jointly define a sealing groove 3. The inner wall surface of the sealing groove 3 comprises a plurality of sealing surfaces 31. At least one sealing surface 31 is formed with a concave-convex structure 313. The sealing member 4 is accommodated in the sealing groove 3 and contacts the sealing surface 31. The sealing member 4 is interference fit with the sealing groove 3. The sealing groove 3 can facilitate the accommodation of the sealing member 4 therein and can make the overall structure of the sealing member 4, the first component 1 and the second component 2 compact. By having the sealing member 4 located in the sealing groove 3 jointly defined by the first component 1 and the second component 2 and having the sealing member 4 contact the sealing surface 31, the sealing effect between the first component 1 and the second component 2 can be enhanced, and the possibility of leakage of liquid, gas, etc. through the fitting gap between the first component 1 and the second component 2 can be reduced or avoided. The sealing surface 31 is formed with a concave-convex structure 313, which can effectively change the stress distribution of the contact surface between the sealing surface 31 and the seal 4, thereby increasing the contact stress between the sealing surface 31 and the seal 4, which is beneficial to improving the overall sealing effect of the sealing assembly 100.

[0035] Due to the interference fit between the seal 4 and the sealing groove 3, the part of the seal 4 that contacts the concave-convex structure 313 on the sealing surface 31 is squeezed to form a corresponding convex-concave structure, which can change the contact stress distribution of the sealing surface 31. For example, the contact stress between the concave-convex structure of the sealing surface 31 and the convex-concave structure of the seal 4 can be made greater to enhance the overall sealing effect of the sealing assembly 100.

[0036] A concave-convex structure 313 is formed by at least one sealing surface 31, the seal 4 is accommodated in the sealing groove 3 and the seal 4 contacts the sealing surface 31, and the seal 4 and the sealing groove 3 have an interference fit. For example, when the compression rate of the seal 4 is the same, such a sealing assembly 100 can provide a better sealing effect.

[0037] For example, when the sealing assembly 100 is used for the cylinder of an air compressor, the first component 1 can be a cylinder head, and the second component 2 can be a cylinder body. The cylinder head and the cylinder body jointly define a sealing groove 3. When the gas pressure in the cylinder body is too high, the gas pressure in the cylinder body will cause a certain impact on the seal 4 and reduce the sealing effect of the seal 4. Through the interference fit between the seal 4 and the sealing groove 3, the part of the seal 4 that contacts the concave-convex structure 313 on the sealing surface 31 is squeezed to form a corresponding convex-concave structure, which can change the stress distribution of the contact surface between the sealing surface 31 and the seal 4 to increase the contact stress between the sealing surface 31 and the seal 4, thereby improving the sealing effect of the sealing assembly 100 for the fitting gap between the cylinder head and the cylinder body, and reducing or avoiding the possibility of gas or liquid leakage through the fitting gap between the cylinder head and the cylinder body.

[0038] In the description of the present invention, “plurality” means two or more.

[0039] According to the sealing assembly 100 of the embodiment of the present invention, the inner wall surface of the sealing groove 3 includes multiple sealing surfaces 31, at least one sealing surface 31 is formed with a concave-convex structure 313, the seal 4 is interference fit with the sealing groove 3, and the part of the seal 4 that contacts the concave-convex structure 313 on the sealing surface 31 is extruded to form a corresponding convex-concave structure, which can change the stress distribution of the contact surface between the sealing surface 31 and the seal 4, thereby increasing the contact stress between the sealing surface 31 and the seal 4, which is beneficial to improving the overall sealing effect of the sealing assembly 100.

[0040] Reference Figure 1-Figure 3According to some embodiments of the present invention, the sealing groove 3 extends in an elongated strip shape, and the concave-convex structure 313 includes at least one groove 314. The groove 314 extends along the extension direction of the sealing groove 3. The width of the groove 314 at its maximum width is D1. The width of the groove 314 is perpendicular to the extension direction of the groove 314. The depth of the groove 314 is D2. The ratio of D1 to D2 ranges from 2 to 15. For example, the ratio of D1 to D2 can range from 2, 5, 7, 11, 15, etc. By ensuring that the ratio of D1 to D2 is not less than 2, the groove 314 can be prevented from being too steep, thereby preventing excessive contact stress at the groove 314. Excessive contact stress can cause permanent deformation of the seal 4 and lead to sealing failure. By ensuring that the ratio of D1 to D2 is not greater than 15, the distribution of contact stress between the contact surface of the seal 4 and the sealing surface 31 can be changed, effectively increasing the contact stress between the sealing surface 31 and the seal 4, thereby enhancing the overall sealing effect of the sealing assembly 100.

[0041] For example, if the ratio range of D1 to D2 is greater than 15, the groove 314 of the sealing surface 31 is too flat. Compared with the sealing surface 31 without the concave-convex structure 313, the surface contact stress of the seal 4 with the concave-convex structure 313 changes less, resulting in a smaller change in the sealing effect of the sealing assembly 100. By ensuring that the ratio range of D1 to D2 is not greater than 15, the contact stress on the surface of the sealing surface 31 can be effectively changed, thereby enhancing the sealing effect of the seal 4.

[0042] By setting the ratio of D1 to D2 in the range of 2 to 15, the contact stress between the sealing surface 31 and the surface of the seal 4 is effectively increased to enhance the sealing effect of the seal 4 while also preventing the seal 4 from failing due to excessive contact stress.

[0043] Reference Figure 1-Figure 3 According to some embodiments of the present invention, the Shore A hardness of the seal 4 is less than or equal to 80. For example, the Shore A hardness of the seal 4 can be 50, 58, 65, 74, 80, etc. By making the Shore A hardness of the seal 4 less than or equal to 80, the seal 4 can be made softer. When the seal 4 is interference-fitted with the sealing surface 31, the portion of the softer seal 4 that is more likely to contact the concave-convex structure 313 on the sealing surface 31 is squeezed to form a corresponding concave-convex structure, thereby enhancing the sealing effect of the seal 4.

[0044] For example, if the Shore A hardness of the seal 4 is greater than 80, the seal 4 is too hard and difficult to fit into the sealing groove 3, making assembly of the seal 4 difficult. Furthermore, when the seal 4 is interference-fitted with the sealing surface 31, the portion of the seal 4 that contacts the concave-convex structure 313 of the sealing surface 31 is not easily squeezed to form a corresponding concave-convex structure, resulting in a poor sealing effect of the seal 4. By having a Shore A hardness of less than or equal to 80, the seal 4 can be assembled more smoothly into the sealing groove 3 and achieve a better sealing effect.

[0045] Reference Figure 1-Figure 3 According to some embodiments of the present invention, when the Shore A hardness of the seal 4 is between 50 and 80, the ratio of D1 to D2 is in the range of 2.5 to 15. For example, the ratio of D1 to D2 can be in the range of 2.5, 5, 7, 11, 15, etc. When the Shore A hardness of the seal 4 is between 50 and 80, by ensuring that the ratio of D1 to D2 is not less than 2.5, the groove 314 can be prevented from being too steep, thereby preventing excessive contact stress at the groove 314. Excessive contact stress can cause permanent deformation of the seal 4 and lead to sealing failure. By ensuring that the ratio of D1 to D2 is not greater than 15, the stress distribution between the sealing surface 31 and the surface of the seal 4 can be effectively changed, thereby effectively increasing the contact stress between the sealing surface 31 and the seal 4, thereby enhancing the overall sealing effect of the sealing assembly 100.

[0046] When the Shore A hardness of the seal 4 is less than 50, the ratio of D1 to D2 is in the range of 2 to 15. For example, the ratio of D1 to D2 can be 2.5, 5, 7, 11, 15, etc. When the Shore A hardness of the seal 4 is less than 50, by ensuring that the ratio of D1 to D2 is not less than 2, the groove 314 can be prevented from being too steep, thereby preventing excessive contact stress at the groove 314, which can cause permanent deformation of the seal 4 and lead to sealing failure. By ensuring that the ratio of D1 to D2 is not greater than 15, the stress distribution between the sealing surface 31 and the surface of the seal 4 can be effectively changed, thereby effectively increasing the contact stress between the sealing surface 31 and the seal 4, thereby enhancing the overall sealing effect of the sealing assembly 100.

[0047] By setting the ratio of D1 to D2 in the range of 2.5 to 15 when the Shore A hardness value of the seal 4 is between 50 and 80, and setting the ratio of D1 to D2 in the range of 2 to 15 when the Shore A hardness value of the seal 4 is less than 50, precise control of the seal 4 at different hardnesses can be achieved, so as to better balance the sealing effect of the seal 4 and the contact stress of the seal 4.

[0048] Reference Figure 3 and Figure 4According to some embodiments of the present invention, the sealing groove 3 extends in a long strip shape, and the concave-convex structure 313 includes at least one groove 314. The groove 314 extends along the extension direction of the sealing groove 3. The width of the groove 314 at the maximum width position is D1. The width direction of the groove 314 is perpendicular to the extension direction of the groove 314. The equivalent diameter of the cross section of the seal 4 is D3. The ratio of D3 to D1 ranges from 2 to 20. The equivalent diameter D3 of the cross section of the seal 4 refers to the diameter of a circle with the same area as the cross section of the seal 4. For example, the ratio of D3 to D1 can be 2, 5, 8, 13, 17, 20, etc. By ensuring that the ratio of D3 to D1 is not less than 2, it can be ensured that the portion of the seal 4 that contacts the groove 314 on the sealing surface 31 is squeezed to form a corresponding protrusion 315 with a smaller width at the maximum position, thereby effectively increasing the contact stress between the sealing surface 31 and the surface of the seal 4, thereby enhancing the sealing effect of the seal 4; by ensuring that the ratio of D3 to D1 is not greater than 20, the number of grooves 314 on the surface of the sealing surface 31 can be reduced while improving the sealing effect of the seal 4, thereby reducing the processing difficulty of the first component 1 or the second component 2, making the first component 1 or the second component 2 easier to manufacture.

[0049] By setting the ratio of D3 to D1 to be in the range of 2 to 20, the contact stress between the sealing surface 31 and the surface of the sealing member 4 can be effectively increased while facilitating the manufacturing of the first component 1 or the second component 2 .

[0050] In addition, when the ratio of D3 to D1 is within the range of 2 to 20, the larger the ratio of D3 to D1, the greater the contact stress of the surface of the seal 4 in contact with the sealing surface 31 when the compression amount of the seal 4 is the same, and the better the sealing effect of the sealing assembly 100.

[0051] Reference Figure 1-Figure 3 According to some embodiments of the present invention, the sealing groove 3 extends in a long strip shape, and the concave-convex structure 313 includes at least one groove 314, which extends along the extension direction of the sealing groove 3. The cross-sectional edge line of the groove 314 is a curve, so that the cross-sectional edge line of the groove 314 forms a continuous line. Correspondingly, the portion of the seal 4 that contacts the groove 314 on the sealing surface 31 is squeezed to form a corresponding cross-sectional edge line of the protrusion 315, which can also form a continuous curve, so as to reduce or prevent the phenomenon of stress concentration on the surface of the seal 4.

[0052] Reference Figure 1-Figure 3According to some embodiments of the present invention, the sealing groove 3 extends in a long strip shape, and the concave-convex structure 313 includes a groove 314 and a protrusion 315. The groove 314 and the protrusion 315 both extend along the extension direction of the sealing groove 3. The groove 314 is defined between adjacent protrusions 315. The cross-sectional edge line of the protrusion 315 is a curve, so that the cross-sectional edge line of the protrusion 315 forms a continuous line. Correspondingly, the portion of the seal 4 that contacts the protrusion 315 on the sealing surface 31 is squeezed to form a corresponding cross-sectional edge line of the groove 314, which can also form a continuous curve to reduce or prevent stress concentration on the surface of the seal 4.

[0053] Reference Figure 1-Figure 3 According to some embodiments of the present invention, the sealing groove 3 extends in a long strip shape, and the concave-convex structure 313 includes a groove 314 and a protrusion 315. The groove 314 and the protrusion 315 both extend along the extension direction of the sealing groove 3, and a groove 314 is defined between adjacent protrusions 315. At least one sealing surface 31 is formed with a plurality of grooves 314 and protrusions 315 located between adjacent grooves 314. The plurality of grooves 314 on a single sealing surface 31 are arranged at intervals along the width direction of the sealing surface 31, and the width direction of the sealing surface 31 is perpendicular to the extension direction of the sealing groove 3. For example, the concave-convex structure 313 may include 1, 2, 3, 4, 5, etc. grooves 314 and 1, 2, 3, 4, 5, etc. protrusions 315. The part of the seal 4 that contacts the concave-convex structure 313 on the sealing surface 31 is extruded to form 1, 2, 3, 4, 5, etc. protrusions 315 and 1, 2, 3, 4, 5, etc. grooves 314. The number of protrusions 315 extruded on the seal 4 is the same as and corresponds one-to-one to the number of grooves 314 in the concave-convex structure 313 on the sealing surface 31. The number of grooves 314 extruded on the seal 4 is the same as and corresponds one-to-one to the number of protrusions 315 in the concave-convex structure 313 on the sealing surface 31.

[0054] The convex-concave structure on the seal 4 cooperates with the concave-convex structure 313 on the sealing surface 31 , thereby achieving a multi-stage sealing effect, thereby further enhancing the sealing effect of the seal 4 on the first component 1 and the second component 2 .

[0055] Reference Figure 1-Figure 3 According to some embodiments of the present invention, the sealing groove 3 is annular, and the sealing member 4 is an annular sealing member, which can better effectively seal the fitting gap extending along the annular direction between the first component 1 and the second component 2, thereby reducing or avoiding the possibility of gas or liquid leaking through the fitting gap between the first component 1 and the second component 2.

[0056] Reference Figure 1-Figure 3According to some embodiments of the present invention, the plurality of sealing surfaces 31 include a first sealing surface 311 and a second sealing surface 312. The first sealing surface 311 and the second sealing surface 312 are arranged opposite each other along the radial direction of the sealing groove 3. A concave-convex structure 313 is formed on at least one of the first sealing surface 311 and the second sealing surface 312. When the seal 4 is accommodated in the sealing groove 3, due to the interference fit between the sealing groove 3 and the seal 4, the concave-convex structure 313 formed on at least one of the first sealing surface 311 and the second sealing surface 312 causes the portion of the seal 4 that contacts the concave-convex structure 313 on the first sealing surface 311 or the second sealing surface 312 to be squeezed to form a corresponding concave-convex structure, thereby effectively increasing the contact stress between the surfaces of the seal 4 and the sealing surface 31, thereby enhancing the overall sealing effect of the sealing assembly 100.

[0057] Among them, the concave-convex structure 313 formed on at least one of the first sealing surface 311 and the second sealing surface 312 may include the following situations: for example, the concave-convex structure 313 may be formed on the first sealing surface 311 or the second sealing surface 312; for another example, the concave-convex structure 313 may be formed on both the first sealing surface 311 and the second sealing surface 312.

[0058] Reference Figure 1-Figure 3 According to some embodiments of the present invention, an annular receiving groove 11 is formed in the first component 1. The second component 2 and the inner wall of the receiving groove 11 jointly define a sealing groove 3. The bottom wall of the receiving groove 11 constitutes a first sealing surface 311, and the surface of the second component 2 facing the receiving groove 11 constitutes a second sealing surface 312. A concave-convex structure 313 is formed on the second sealing surface 312. The receiving groove 11 facilitates the reception of the sealing element 4 therein. The second component 2 and the inner wall of the receiving groove 11 jointly define the sealing groove 3. The concave-convex structure 313 is formed on at least one of the second sealing surfaces 312. When the sealing groove 3 and the sealing element 4 are interference-fitted, the portion of the sealing element 4 that contacts the concave-convex structure 313 on the second sealing surface 312 is squeezed to form a corresponding concave-convex structure. This can change the stress distribution between the sealing surface 31 and the sealing element 4, thereby increasing the contact stress between the sealing element 4 and the sealing surface 31, thereby enhancing the overall sealing effect of the sealing assembly 100 and reducing or preventing the possibility of gas or liquid leakage through the clearance between the first component 1 and the second component 2.

[0059] Reference Figure 1-Figure 3According to some embodiments of the present invention, the second component 2 is sleeved on the outer circumference of the first component 1, and the first and second components 1 and 2 are connected by a threaded structure 21. The threaded structure 21 and the sealing groove 3 are arranged along the axial direction of the second component 2. The connection between the first and second components 1 and 2 via the threaded structure 21 can simplify the connection between the first and second components 1 and 2 and provide strong stability. The threaded structure 21 and the sealing groove 3 are arranged along the axial direction of the second component 2, and the sealing groove 3 extends annularly, which can effectively seal the fitting gap between the first and second components 1 and 2 along the annular extension.

[0060] For example, the assembly process of the seal 4 with the first component 1 and the second component 2 can be: first, the seal 4 is accommodated in the sealing groove 314, and then the first component 1 is threadedly connected to the second part to complete the assembly process of the seal 4 with the first component 1 and the second component 2.
