Description

Technical Field

[0001] The utility model relates to the technical field of cylinder heads, in particular to a cylinder head structure of a motorcycle engine. Background Art

[0002] The cylinder head seals the cylinder and, together with the piston, forms the combustion chamber. It is a crucial component of the engine's combustion chamber, ensuring smooth intake and ignition of gases. It also bears the brunt of the high-temperature, high-pressure gases during combustion. The cylinder head withstands the mechanical loads of the gases and the tightening of the cylinder bolts. Furthermore, contact with the hot gases creates high thermal loads. To ensure a good seal, the cylinder head casting material must possess sufficient strength and rigidity while also being heat-resistant to prevent thermal deformation. Furthermore, because the cylinder head is constantly exposed to high temperatures during engine operation, relying solely on the material's properties to withstand these temperatures can severely impact its service life. This often necessitates a water-cooling system. Currently, cylinder heads with water-cooling systems are typically cast in one piece. This method not only requires complex manufacturing processes but also makes subsequent maintenance difficult. Furthermore, the integrally cast water-cooling cavity reduces the cylinder head's mechanical load capacity.

[0003] In order to solve the above technical problems, the Chinese patent with announcement number CN216922302U in the prior art discloses a high-temperature resistant cylinder head for a motorcycle engine, including an upper end cover and a lower end cover, the upper end cover is provided with a detachable connecting mechanism, the upper end cover is installed on the lower end cover through the detachable connecting mechanism, and a coolant cavity is provided between the upper end cover and the lower end cover, and cooling interfaces A and cooling interfaces B are symmetrically provided on both sides of the upper end cover, and the cooling interfaces A and cooling interfaces B are both connected to the coolant cavity.

The disassembly and assembly are time-consuming and labor-intensive, which increases the workload of the staff and affects work efficiency. Utility Model Content

[0027] In this embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, the reset locking assembly includes a docking block 6 installed at one end of the top of the second mounting platform 4, and a docking groove is provided at one end of the bottom of the first mounting platform 2. The docking groove and the docking block 6 are slidably connected. A locking groove is provided on one side of the docking groove inside the first mounting platform 2, and a limit seat 7 is installed on one side of the inner wall of the locking groove. The top of the limit seat 7 is overlapped with a fitting plate 8. First, the first mounting platform 2 is overlapped on the rubber pad 3 so that a part of the docking block 6 enters the inside of the docking groove, and continues to squeeze downward to allow the rubber pad 3 to retract. The docking block 6 gradually moves down and counteracts the inclined surface on the fitting plate 8, forcing the fitting plate 8 to drive the limit block 9 to slide inside the limit groove, while squeezing the first spring 10 and stretching the second spring 19.

[0028] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, a limiting groove is provided at the top of the limiting seat 7, and a limiting block 9 is slidably connected to the inner side of the limiting groove. One end of the limiting block 9 is fixedly connected to one side of the bonding plate 8. A first spring 10 is installed between one side of the limiting block 9 and the inner wall of the limiting groove. A stretching groove is provided on one side of the bonding plate 8, and a second spring 19 is installed between the inner wall of the stretching groove and the inner wall of the locking groove. The opposite ends of the docking block 6 and the bonding plate 8 are provided with inclined surfaces that fit together. A rotating groove is provided inside the bonding plate 8 at its inclined surface. A rotating rod is rotatably connected to the inner side of the rotating groove. An abutment plate 11 is sleeved on the outer side of the rotating rod. One side of the abutment plate 11 is provided with an inclined surface that fits the inclined surface. The slope of the combination is formed, a torsion spring 12 is installed between the rotating rod and the inner wall of the rotating groove, and an abutment groove is opened inside the docking block 6 at its inclined surface. Then, as the docking block 6 continues to descend, it contacts the abutment plate 11 and forces the rotating rod to rotate, and the torsion spring 12 retracts until the abutment groove is close to the rotating groove. The abutment plate 11 is ejected to the inside of the abutment groove by the torsion spring 12, and then no longer squeezes the upper end cover 1 and the first mounting platform 2, so that the rubber pad 3 rebounds a short distance, and the docking block 6 also moves a short distance, so that one end of the abutment plate 11 can abut against the inner wall of the abutment groove, completing the position locking of the upper end cover 1 and the lower end cover 5.

[0029] In this embodiment, if Figure 1 、 Figure 3 and Figure 4As shown, the protective component includes a closing groove opened on one side of the outer wall of the first mounting platform 2, the inner side of the closing groove is connected to the inner side of the operating groove, a closing cover 15 is slidably connected to the inner side of the closing groove, a synchronization groove 16 is opened on one side of the inner wall of the closing groove, one end of the closing cover 15 is installed with a synchronization block slidably connected to the synchronization groove 16, a drag groove 17 is opened on one side of the closing cover 15, one end of the interior of the closing cover 15 is embedded with a first fixing member, and one end of the inner wall of the closing groove is embedded with a second fixing member 18 corresponding to the first fixing member. One of the first fixing member and the second fixing member 18 is a first magnet, and the other of the first fixing member and the second fixing member 18 is a second magnet. The magnetic poles of the first magnet and the second magnet are opposite and attract each other. Further, after the locking is completed, the drag groove 17 on the closing cover 15 can be buckled, and the synchronization block and the synchronization groove 16 can be slid toward the inner side of the closing groove to close the pull ring 14 inside the operating groove, so that the first fixing member and the second fixing member 18 are adsorbed and positioned with each other to prevent the person from accidentally touching the pull ring 14 after the assembly is completed, causing the connection to become loose.

[0030] In this embodiment, if Figure 1 、 Figure 3 and Figure 4 As shown, the dragging assembly includes a mounting groove provided on one side of the docking block 6, and a movable rod 13 is installed inside the mounting groove.

Furthermore, when it is necessary to unlock the positioning for inspection and maintenance operations, the closing cover 15 can be reopened, and then the pull ring 14 is buckled to drive the movable rod 13 to slide inside the movable groove, while driving the bonding plate 8 to move synchronously, squeezing the first spring 10 again and stretching the second spring 19, so that the abutment plate 11 moves horizontally away from the inside of the abutment groove. At this time, the docking block 6 is no longer abutted, and the rubber pad 3 rebounds completely. The docking block 6 will move a distance inside the docking groove as the rubber pad 3 bounces up, and at this time, releasing the pull ring 14 will not cause re-engagement.

When the first support 2 is in the air, the second support 2 is in the air, and the second support 2 is in the air, so that the second support 2 is in the air. When the first support 2 is in the air, the second support 2 is in the air, and the second support 2 is in the air, so that the second support 2 is in the air. The locking is completed. After the locking is completed, the drag groove 17 on the closing cover 15 can be buckled, and the synchronous block and the synchronous groove 16 can be slid toward the inside of the closing groove to close the pull ring 14 inside the operating groove, so that the first fixing member and the second fixing member 18 are adsorbed and positioned with each other to prevent the personnel from accidentally touching the pull ring 14 after the assembly is completed, causing the connection to become loose. When the positioning needs to be unlocked for inspection and maintenance operations, the closing cover 15 can be reopened, and then the pull ring 14 is buckled to drive the movable rod 13 to slide inside the movable groove, and at the same time drive the fitting plate 8 to move synchronously, squeeze the first spring 10 again and stretch the second spring 19, so that the abutment plate 11 moves horizontally away from the inside of the abutment groove. At this time, the docking block 6 is no longer abutted, and the rubber pad 3 rebounds completely. The docking block 6 moves a distance inside the docking groove as the rubber pad 3 bounces up, and there will be no re-engagement when the pull ring 14 is released.
