[0018] Figure 1 A schematic structural diagram of a cylinder head assembly provided in an embodiment of the present application. DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] refer to Figure 1 The cylinder head assembly provided in the embodiment of the present application includes: a cylinder head 101, a plurality of support seats 102 are spaced apart along a first direction (reference x-axis direction) on the mounting surface S of the cylinder head 101, and the plurality of support seats 102 are an integral structure with the cylinder head 101, for example, the cylinder head 101 and the plurality of support seats 102 are an integrally cast structure, the processing technology is simple, and the structure is stable, wherein the first direction (reference x-axis direction) is parallel to the mounting surface S; each support seat 102 is provided with a rocker shaft connection structure as a rocker arm seat, and the rocker shaft connection structure is used to fix the rocker arm shaft. The support seat 102 is an integral structure with the cylinder head 101, and there is no need to disassemble and assemble the support seat 102 additionally, which simplifies the process, reduces bolts and other parts, and reduces costs.

[0021] In a specific embodiment, the rocker shaft connection structure includes a bolt hole T3, and a bolt can be directly used to penetrate the rocker shaft and fixed to the bolt hole T3 by thread. The assembly is simple and no top cover is required to fix the rocker shaft.

[0022] Among them, the surface of each support seat 102 away from the mounting surface S is provided with a rocker shaft fixing groove T2 extending along the first direction (reference x-axis direction), and the rocker shaft is placed in the rocker shaft fixing groove T2 to position the rocker shaft. At this time, the bolt hole T3 can be located at the bottom surface of the rocker shaft fixing groove T2, and because the rocker shaft fixing groove T2 can prevent the rocker shaft from rotating in a direction parallel to the mounting surface S, each support seat 102 only needs to be provided with one bolt hole T3, and one bolt is used to fix the rocker shaft to the bolt hole T3. However, it should be understood that the rocker shaft fixing groove T2 may not be provided, but a plane may be used, and at least two bolt holes T3 are provided in the area corresponding to the plane, and the rocker shaft is fixed to the corresponding bolt holes T3 on the support seat 102 by at least two bolts to prevent the rocker shaft from twisting relative to the support seat 102.

[0023] In a specific embodiment, the rocker shaft fixing groove T2 may be a circular arc groove, which is used to place a rocker shaft with the same outer diameter, so as to fit the shape of the rocker shaft and position the rocker shaft more stably. In addition, the circular arc groove can avoid stress concentration problems and is easy to process. However, the form of the rocker shaft fixing groove T2 is not limited to a circular arc groove, and may also be a groove of other shapes, as long as the rocker shaft can be positioned.

[0024] In the related technical solutions, the bearing cap of the camshaft is also fixed to the cylinder head by bolts, and the shaft hole and the rocker arm seat of the camshaft are processed separately, which will also cause problems such as many parts, high cost and complicated process. In order to solve the above problems, in a specific embodiment, each support seat 102 is provided with a camshaft hole T1, and the camshaft hole T1 passes through the corresponding support seat 102 along the first direction (reference x-axis direction). The camshaft hole T1 forms a tunnel structure and is also integrated on the support seat 102, which can reduce the combination, processing and disassembly of the camshaft bearing cap, camshaft bushing and camshaft hole.

[0025] In a specific embodiment, in each support seat 102, the camshaft hole T1 and the rocker shaft fixing slot T2 are staggered along the second direction (referenced to the y-axis direction); wherein the second direction (referenced to the y-axis direction) is parallel to the mounting surface S and perpendicular to the first direction (referenced to the x-axis direction). In other words, the camshaft hole T1 and the rocker shaft fixing slot T2 are staggered along the second direction (referenced to the y-axis direction).

[0026] Based on the same inventive concept, the embodiment of the present application also provides an engine, which includes a rocker shaft and the cylinder head assembly provided in the above embodiment, wherein the rocker shaft is fixedly connected to the support seat 102 through a rocker shaft connection structure. The function of the engine can refer to the relevant description of the cylinder head assembly above.

[0027] In a specific embodiment, the engine further includes a valve stem; when each support seat 102 is provided with a camshaft hole T1, the camshaft sequentially penetrates and is rotatably connected to the camshaft holes T1 of the multiple support seats 102; multiple cams are fixedly connected to the camshaft, and multiple rocker arms are rotatably connected to the rocker arm shaft, one end of each rocker arm abuts against the corresponding cam, and the other end is transmission-connected to the valve stem. When the camshaft rotates, the cam is driven to rotate, and the cam drives the corresponding end of the rocker arm to swing, and the rocker arm forms a lever, and the other end away from the cam drives the valve stem to realize the intake and exhaust actions.

[0028] Based on the same inventive concept, the embodiment of the present application further provides a vehicle, which includes the engine provided in the above embodiment. The function of the vehicle can refer to the above description of the engine.

[0029] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
