[0034] Figure 1 Schematically shown is an assembly schematic diagram of a cylinder head cover support structure according to an embodiment of the present invention, a post-treatment component 10, and an air filter component 20 from a certain perspective. As Figure 1 shown, the present invention provides an engine cylinder head cover support structure, including a cylinder head cover housing 100, a post-treatment bracket 200, and an air filter bracket 400. A first connection portion 110 and a second connection portion 120 are provided on the cylinder head cover housing 100. The post-treatment bracket 200 is connected to the first connection portion 110, and the post-treatment bracket 200 is used to connect the post-treatment component 10. The air filter bracket 400 is connected to the second connection portion 120, and the air filter bracket 400 is used to connect the air filter component 20.

[0035] By using the cylinder head cover support structure in the present technical solution, the post-treatment bracket 200 and the air filter bracket 400 can be integrated into the cylinder head cover housing 100 to realize the support for the post-treatment component 10 and the air filter component 20.

Therefore, by adopting this cylinder head cover support structure, there is no need to connect the post-treatment component 10 and the air filter component 20 to the cylinder head or the flywheel housing through large auxiliary brackets, which can significantly save the installation space, reduce the number of parts, improve the assembly efficiency, and save the production cost.

[0036] Further, referring still to Figure 1 , the engine cylinder head cover support structure further includes a hoop 500. Both ends of the hoop 500 are respectively connected to the post-treatment bracket 200, and the hoop 500 is used to connect the post-treatment component 10.

[0037] Optionally, after the post-treatment component 10 and the cylinder head cover support structure are assembled, the length direction of the post-treatment bracket 200 is perpendicular to the length direction of the post-treatment component 10. Preferably, the length of the post-treatment bracket 200 is greater than or equal to the outer diameter of the post-treatment component 10, so that the post-treatment bracket 200 can have sufficient space to connect with the ends of the hoop 500. In one embodiment, when fixing the post-treatment component 10, first place the post-treatment component 10 on the post-treatment bracket 200, then sleuth the hoop 500 on the hoop 500, and connect both ends of the hoop 500 to the post-treatment bracket 200 respectively.

[0038] Further, the post-processing component 10 is generally cylindrical, and the middle part of the post-processing bracket 200 contacts the bottom of the post-processing component 10. Optionally, the middle part of the post-processing bracket 200 is set to an arc shape that fits the shape of the post-processing component 10, so as to provide stable support for the post-processing component 10 and be able to limit the position of the post-processing component 10 to prevent the post-processing component 10 from rolling during the assembly process.

[0039] Further, since the length of the post-processing component 10 is relatively long, multiple post-processing brackets 200 are provided, and the multiple post-processing brackets 200 are arranged at intervals along the length direction of the post-processing component 10. Correspondingly, multiple hoop brackets 500 are provided, and each hoop bracket 500 is connected to a post-processing bracket 200. In this embodiment, the number of both the post-processing brackets 200 and the hoop brackets 500 is two. Additionally, since the length of the post-processing component 10 is relatively long, in order to stably connect the post-processing component 10 to the post-processing bracket 200, it should be ensured that the interval between the two post-processing brackets 200 has sufficient length. To increase the distance between the two post-processing brackets 200, the length direction of the cylinder head cover housing 100 and the length direction of the post-processing component 10 are arranged at an angle, and an extension plate 130 is provided on the cylinder head cover housing 100, and the post-processing bracket 200 is connected to the extension plate 130. In other embodiments, the number of post-processing brackets 200 can be three, four, five, etc., which are not specifically limited herein, and the number of hoop brackets 500 is set according to the number of post-processing brackets 200. By adopting this method, the assembly is convenient, and effective support and fixation of the post-processing component 10 can be achieved.

[0040] Further, connecting pins 300 are respectively provided at both ends of the post-processing bracket 200, and connecting sleeves are respectively provided at both ends of the hoop bracket 500, and one connecting sleeve is sleeved on a corresponding connecting pin 300.

[0041] Optionally, the part of the hoop bracket 500 in contact with the post-processing component 10 is a single-layer strip structure, and its end is bent upward to form a connecting sleeve.

Optionally, the length direction of the connecting pin 300 is parallel to the length direction of the post-processing component 10.

[0042] Further, the post-processing bracket 200 includes a horizontal part 210 and two vertical parts 220 arranged at intervals. The two vertical parts 220 are connected by the horizontal part 210. The horizontal part 210 is connected to the cylinder head cover housing 100. Both ends of the connecting pin 300 are respectively connected to the two vertical parts 220, and the part of the connecting pin 300 located between the two vertical parts 220 passes through the connecting sleeve.

[0043] Optionally, through holes for passing through the connecting pin 300 are provided on the vertical portion 220. In one embodiment, a limiting protrusion is provided at one end of the connecting pin 300, and an external thread is provided at the other end. After the connecting pin 300 penetrates into the vertical portion 220, one end is limited by the limiting protrusion, and the other end penetrates out of the vertical portion 220 and is locked by a nut. In another embodiment, both ends of the connecting pin 300 can be connected to the two vertical portions 220 by welding respectively. Optionally, the top of the vertical portion 220 is recessed downward to form an arc that matches the shape of the air filter component 20, thereby providing stable support for the air filter component 20. Optionally, the horizontal portion 210 and the vertical portion 220 are perpendicularly arranged, and in order to reduce stress concentration, the connection between the horizontal portion 210 and the vertical portion 220 is connected by a fillet transition. Optionally, the horizontal portion 210 and the vertical portion 220 are of an integrally formed structural form.

[0044] Further, a shock pad 600 is provided on the cylinder head cover housing 100, and the aftertreatment bracket 200 is arranged on the shock pad 600.

[0045] The aftertreatment component 10 processes harmful components in the exhaust gas through different technical means, such as catalytic conversion, particulate trapping, nitrogen oxide storage and conversion, etc. Maintaining the safe and stable operation of the aftertreatment component 10 is crucial for the performance of the whole vehicle. Vibration is an important factor leading to the failure of the aftertreatment component 10, mainly affecting its durability and reliability. Vibration may cause key components in the aftertreatment component 10 to loosen or fall off, and may also cause signal distortion or inaccurate actuator operation. By providing the shock pad 600, the vibration generated during the operation of the aftertreatment component 10 can be effectively absorbed, the damage caused by vibration can be reduced, and the service life of the aftertreatment component 10 can be effectively extended. Optionally, the shock pad 600 can be a rubber pad or a silica gel pad. Optionally, the shock pad 600 can be cylindrical or prismatic, etc. Further, the first connection portion 110 can be a connecting column, and a threaded hole is provided on the connecting column. Both the shock pad 600 and the bracket are provided with through holes for passing through bolts. When connecting, the bracket and the shock pad 600 are connected to the connecting column by bolts.

[0046] Further, Figure 2 Schematically shows an assembly schematic diagram of the cylinder head cover support structure, the aftertreatment component 10, and the air filter component 20 according to an embodiment of the present invention from another perspective. Refer to Figure 1 and Figure 2 , the air filter bracket 400 includes a first connecting plate 410 and a second connecting plate 420 arranged at an angle. The first connecting plate 410 is connected to the second connecting portion 120, and the second connecting plate 420 is used to connect the air filter component 20.

[0047] Optionally, the first connecting plate 410 and the second connecting plate 420 are integrally formed. Optionally, the first connecting plate 410 and the second connecting plate 420 are perpendicularly arranged. By setting the air filter bracket 400 in such a structural form, it is possible to conveniently fix the air filter component 20 and the cylinder head cover housing 100. Preferably, to reduce stress concentration, the connection between the first connecting plate 410 and the second connecting plate 420 is transitioned by a fillet.

[0048] Furthermore, the air filter bracket 400 further includes a reinforcing plate 430, and both the first connecting plate 410 and the second connecting plate 420 are connected to the reinforcing plate 430.

[0049] By providing the reinforcing plate 430, the structural strength of the air filter bracket 400 can be increased to prevent the first connecting plate 410 and the second connecting plate 420 from breaking. Optionally, the reinforcing plate 430 and the first connecting plate 410 are perpendicularly arranged. Optionally, the shape of the reinforcing plate 430 can be triangular, trapezoidal, sector-shaped, etc. The number of reinforcing plates 430 can be one or more. When there are multiple reinforcing plates 430, the multiple reinforcing plates 430 are arranged at intervals along the length direction of the first connecting plate 410.

[0050] Furthermore, the second connecting portion 120 is a connecting post, and a threaded hole is provided on the connecting post. A through hole is provided on the first connecting plate 410 for passing a bolt through, and the threaded hole is used for threaded connection with the bolt.

[0051] Optionally, in this embodiment, the second connecting portion 120 and the cylinder head cover housing 100 are integrally formed. The first connecting plate 410 and the second connecting portion 120 are connected by a bolt connection, which is convenient to operate and has a reliable connection.

[0052] Furthermore, multiple air filter brackets 400 are provided, and at least one air filter bracket 400 is provided on each side of the air filter component 20. Optionally, in one embodiment, each first connecting plate 410 is connected to two connecting posts. In other embodiments, the first connecting plate 410 can be connected to one or more than two second connecting portions 120, and the number of the second connecting portions 120 is set according to the usage requirements and is not specifically limited herein.

[0053] It can be understood that by providing air filter brackets 400 on each side of the air filter component 20, the connection stability can be increased to avoid the overall loosening of the air filter component 20 caused by the loosening of one of the air filter brackets 400. In this embodiment, one air filter bracket 400 is provided on each side of the air filter component 20. In other embodiments, multiple air filter brackets 400 can be provided on each side of the air filter component 20 to increase the connection stability.

[0054] The present technical solution also provides an engine assembly, which includes an engine, an after-treatment component 10, an air filter component 20, and the engine cylinder head cover support structure in the above embodiments.
