The engine may be a hydrogen engine, a diesel engine, a gasoline engine, etc. This application takes the cylinder head assembly 100 of a hydrogen engine as an example for description.

[0030] like Figure 1-Figure 4 As shown, the cylinder head assembly 100 of the engine according to the embodiment of the utility model includes: a cylinder head body 10, the top wall of the cylinder head body 10 is formed with a mounting groove 11, a cylinder connecting pipe 12 is fixedly arranged in the mounting groove 11, and the cylinder connecting pipe 12 passes through the bottom wall of the mounting groove 11, and the cylinder connecting pipe 12 is suitable for being connected to the intake pipe of the engine; a limiting structure 20, the limiting structure 20 is fixedly arranged on the cylinder head body 10, and the limiting structure 20 is suitable for abutting against the intake pipe to limit the movement of the intake pipe.

[0031] The top wall of the cylinder head body 10 is formed with a mounting groove 11. As an embodiment of the present application, the mounting groove 11 can be formed in the middle of the top wall of the cylinder head body 10, which helps to maintain the balance of the cylinder head body 10 and reduce stress concentration or vibration caused by uneven weight distribution, thereby improving the safety and reliability of the cylinder head assembly 100. However, the mounting groove 11 can be set at other positions on the top wall of the cylinder head body 10, and can be comprehensively considered and reasonably set according to factors such as the model, specification, and purpose of the engine.

[0032] A cylinder connecting pipe 12 is fixedly arranged in the mounting groove 11, and the cylinder connecting pipe 12 penetrates the bottom wall of the mounting groove 11. The cylinder connecting pipe 12 is suitable for connecting with the intake pipe of the engine, for example, the cylinder connecting pipe 12 and the intake pipe can be connected by threads, or by clamps, or by flanges, but the utility model is not limited thereto, and the cylinder connecting pipe 12 and the intake pipe can also be connected in other ways, as long as the cylinder connecting pipe 12 is suitable for connecting with the intake pipe of the engine, so that the intake pipe can be fixedly installed on the cylinder head body 10, and then hydrogen can enter the engine cylinder through the intake pipe and the cylinder connecting pipe 12, so as to provide normal operation of the engine.

[0033] The limiting structure 20 is fixedly provided on the cylinder head body 10. For example, the limiting structure 20 and the cylinder head body 10 may be fixedly connected by bolts, or the limiting structure 20 and the cylinder head body 10 may be fixedly connected by snap-fitting. However, the present invention is not limited thereto. The limiting structure 20 and the cylinder head body 10 may also be fixedly connected by other means, as long as the limiting structure 20 is fixedly provided on the cylinder head body 10.

As another example, the limiting structure 20 can also have two relatively arranged clamping jaws, and the two clamping jaws clamp the intake pipe. When the limiting structure 20 abuts against the intake pipe to limit the movement of the intake pipe, the risk of the intake pipe loosening or falling off can be reduced, so that the intake pipe is more firmly installed on the cylinder head assembly 100, thereby improving the safety and reliability of the intake pipe.

[0035] According to the cylinder head assembly 100 of the engine in the embodiment of the utility model, the intake pipe can be installed and fixed on the cylinder head body 10 by connecting the cylinder body connecting pipe 12 to the intake pipe of the engine. In addition, the limiting structure 20 is fixed to the cylinder head body 10, and the limiting structure 20 is suitable for abutting against the intake pipe to limit the movement of the intake pipe, which can reduce the risk of loosening or falling off of the intake pipe, so that the intake pipe is more firmly installed on the cylinder head assembly 100, thereby significantly improving the safety and reliability of the cylinder head assembly 100.

[0036] According to some embodiments of the present invention, Figure 1 As shown, along the depth direction of the mounting groove 11, the limiting structure 20 and the cylinder connecting pipe 12 can be arranged correspondingly. When the intake pipe is connected to the cylinder connecting pipe 12, the limiting structure 20 can correspond to the installation position of the intake pipe, so that the limiting structure 20 can abut and limit the intake pipe, thereby ensuring that the intake pipe and the cylinder connecting pipe 12 are stably connected, reducing the risk of the intake pipe loosening or falling off due to vibration, impact or temperature changes, thereby effectively improving the safety and reliability of the cylinder head assembly 100.

[0037] According to some embodiments of the utility model, the limiting structure 20 can be constructed as a heat conducting member, and the limiting structure 20 can be made of a heat conducting material, for example, the limiting structure 20 can be a metal member, and the limiting structure 20 can also be set to be made of an oxide material, and the limiting structure 20 can be made of aluminum oxide, zirconium oxide, sodium oxide, etc. When the interface between the intake pipe and the cylinder connecting pipe 12 generates high temperature, the limiting structure 20 is suitable for conducting the heat of the intake pipe to the cylinder head body 10 to reduce the temperature at the interface between the intake pipe and the cylinder connecting pipe 12, thereby reducing the risk of loosening and falling off of the interface between the intake pipe and the cylinder connecting pipe 12 due to high temperature expansion, thereby improving the connection stability between the intake pipe and the cylinder connecting pipe 12, so as to improve the safety and reliability of the cylinder head assembly 100.

When the intake pipe is assembled in the limiting groove 22, the inner wall of the limiting groove 22 abuts against the intake pipe, thereby limiting the movement of the intake pipe, thereby reducing the risk of the intake pipe becoming loose or falling off due to long-term use, and further improving the safety and reliability of the cylinder head assembly 100.

[0039] According to some embodiments of the present invention, Figure 1 and Figure 4 As shown, a mounting column 13 can be fixedly provided inside the mounting groove 11.

The limiting portion 21 is connected to the heat dissipation portion 24, and the heat dissipation portion 24 is attached to the cylinder head body 10, so that the heat generated by the intake pipe can be transferred to the heat dissipation portion 24 and the cylinder head body 10 through the limiting portion 21, thereby achieving the effect of heat dissipation and cooling of the intake pipe, thereby reducing the risk of loosening and falling off due to high temperature expansion at the interface between the intake pipe and the cylinder body connecting pipe 12, thereby improving the connection stability between the intake pipe and the cylinder body connecting pipe 12, so as to further improve the safety and reliability of the cylinder head assembly 100.

[0042] Furthermore, the heat dissipation portion 24 may include heat dissipation fins, and the heat dissipation fins may increase the heat dissipation area, thereby improving the heat dissipation effect.

[0044] The connecting rod 241 is connected between the limiting portion 21 and the heat dissipation body 242, and the heat dissipation body 242 is fitted with the cylinder head body 10. Heat dissipation fins can be formed on the heat dissipation body 242, which can transfer the heat generated by the intake pipe to the heat dissipation portion 24 and the cylinder head body 10 through the limiting portion 21 and the connecting rod 241, thereby achieving the effect of heat dissipation and cooling the intake pipe, thereby further reducing the risk of loosening or falling off due to high-temperature expansion at the interface between the intake pipe and the cylinder body connecting pipe 12, and further improving the connection stability between the intake pipe and the cylinder body connecting pipe 12, so as to further improve the safety and reliability of the cylinder head assembly 100.

[0046] The inner wall of the mounting groove 11 may be formed with a slide groove 15, and the sliding rod 25 is suitable for being assembled in the slide groove 15 and can slide along the extension direction of the slide groove 15. With such a configuration, the sliding rod 25 can move along the extension direction of the slide groove 15 to adjust the position of the limiting structure 20, so that the limiting structure 20 can smoothly limit the intake pipe, and can accurately limit the intake pipe, thereby improving the connection stability between the cylinder connecting pipe 12 and the intake pipe, and further effectively reducing the risk of the intake pipe loosening or falling off.
