[0024] See also Figure 1-Figure 4 The utility model provides a technical solution: a protective structure for protecting an engine cylinder head, comprising a cylinder head 1, a front side protection assembly 2 is arranged on the front side of the cylinder head 1, the front side protection assembly 2 comprises a front side anti-collision plate 20 arranged on the front side of the cylinder head 1 and two groups of damping liquid cylinders 21 which are symmetrical to each other and respectively arranged on the left and right sides of the cylinder head 1, the front side anti-collision plate 20 protects the front side of the cylinder head 1, and can prevent foreign objects from directly hitting the cylinder head 1;

[0025] Specifically, a connecting rod 23 is slidably connected in the damping fluid cylinder 21, and a piston 24 is fixedly installed at the end of the connecting rod 23 and is located in the damping fluid cylinder 21 and slidably connected to the damping fluid cylinder 21. The damping fluid cylinder 21 contains damping fluid, and when the piston 24 squeezes the damping fluid, a buffering protection effect can be achieved;

[0026] Specifically, a protrusion 271 is rotatably connected to the rod body at the front end of the connecting rod 23 through a rotating shaft, and the protrusion 271 is fixedly mounted on the rear side of the front side anti-collision plate 20. A groove 27 is arranged in the rod body at the front end of the connecting rod 23, and the protrusion 271 is located in the groove 27 and is rotatably connected to the groove walls on both sides of the groove 27 through the rotating shaft, so that the front side anti-collision plate 20 is subjected to the force after the collision to push the connecting rod 23 to move more smoothly; a second spring 22 is arranged between the piston 24 and the rear side wall of the damping fluid cylinder 21, one end of the second spring 22 is fixedly mounted on the inner wall of the damping fluid cylinder 21, and the other end of the second spring 22 is against the piston 24, so that the second spring 22 can be stably placed between the damping fluid cylinder 21 and the piston 24, and the second spring 22 is used for buffering and anti-collision protection. By setting the second spring 22, after the second spring 22 is compressed by force, it can play a further buffering protection effect.

[0027] In the present embodiment, a fixing plate 211 is fixedly installed between the two damping fluid cylinders 21 located on the same side, and the fixing plate 211 is fixedly installed on the frame using fastening bolts, which is convenient for fixing the fixing plate 211 and achieving the effect of fixing the upper and lower damping fluid cylinders 21.

[0028] Furthermore, a first spring 212 is fixedly installed at the center position of the front side surface of the fixing plate 211, a limiting plate 25 is fixedly installed between the two connecting rods 23 located on the same side, and a sleeve 251 is fixedly installed at the center position of the rear side surface of the limiting plate 25.

[0031] When the protective structure for protecting the engine cylinder head of the utility model is in use, the front side anti-collision plate 20 protects the front side of the cylinder head 1. When the front side anti-collision plate 20 is hit, the front side anti-collision plate 20 moves backward and squeezes the third spring 26 to a certain extent. In addition, it drives the connecting rod 23 to move backward. The movement of the connecting rod 23 drives the sleeve 251 to be squeezed onto the first spring 212. In addition, as the movement of the connecting rod 23 drives the piston 24 to move, the movement of the piston 24 will squeeze the second spring 22 and the damping fluid in the damping fluid cylinder 21. The third spring 26, the first spring 212, the second spring 22 and the damping fluid cylinder 21 can buffer and reduce shock during the squeezing process, thereby realizing protection of the engine cylinder head.
