[0033] Specifically, in the process of installing the cover 2, first, the support column 8 at the bottom of the cover 2 is aligned with the hole for installing the screw at the top of the engine 1, and the fixed column 3 is aligned with the hole at the center of the connecting ring 7 at the top of the engine 1, then the cover 2 is moved downward so that the support column 8 enters the hole for installing the screw at the top of the engine 1, and the fixed column 3 also enters the inside of the connecting ring 7, at this time, the inner wall of the engine 1 extrudes the support strip 10 to make it shrink into the inside of the support column 8, and the fixed pin 4 in the fixed column 3 is extruded into the inside of the fixed column 3 by the inner wall of the connecting ring 7, when the bottom end of the fixed column 3 completely enters the inside of the connecting ring 7 and cannot be moved downward, the fixed pin 4 is ejected under the action of the spring 1 and fixes the cover 2 at the top of the engine 1, at this time, the support column 8 completely enters the inside of the hole for installing the screw at the top of the engine 1, and at this time, the support strip 10 is tightly attached to the inside of the hole for installing the screw at the top of the engine 1 under the support of the spring 2, thereby completing the installation of the cover 2, when it is necessary to remove the cover 2, the edge of the cover 2 is held and lifted upward, the inner wall of the connecting ring 7 extrudes the fixed pin 4 to make it shrink into the inside of the fixed column 3, thereby unlocking the cover 2, at this time, the support strip 10 in the support column 8 will shrink inwardly due to the extrusion of the hole wall of the engine 1, thereby removing the support of the cover 2.

[0034] Referring to Figure 5 The bottom of the cover 2 is fixedly connected with a plurality of heat dissipation fins 13 for absorbing heat generated by the engine 1, each of the heat dissipation fins 13 is arranged in parallel array at the top of the engine 1, the bottom of the cover 2 is fixedly connected with a plurality of heat dissipation fins 14 for absorbing heat generated by the engine 1, each of the heat dissipation fins 14 is arranged in parallel array at the top of the engine 1, a plurality of fixed frames 15 are fixedly connected inside the cover 2 for fixing the ventilation net 16, each of the fixed frames 15 is fixedly connected with the ventilation net 16 inside for dissipating heat generated by the engine 1, a plurality of air inlets 17 are arranged at the top of each of the covers 2 for flowing in air, a plurality of air outlets 18 are arranged at the top of each of the covers 2 for flowing out air, a plurality of air ducts 19 are arranged inside each of the covers 2 for flowing air to guide the heat absorbed by the cover 2 out, the air inlets 17 and the air outlets 18 are arranged in symmetrical array at the top of the cover 2.

[0035] Specifically, when the engine 1 is in the running state, a large amount of heat is continuously generated, at this time, the heat dissipation fins one 13 and the heat dissipation fins two 14 quickly absorb a part of the heat by virtue of the large area of the metal surface, and then guide the heat to the inside of the cover 2. In the process of high-speed driving of the automobile, part of the external cold air enters from the air inlet 17, and the cold air flows through the air duct 19 at a very fast speed, and finally roars out from the air outlet 18. In this process, the air carries out the heat in the cover 2, and the remaining part of the heat is discharged through the ventilation net 16. The ventilation net 16 allows the heat to be dissipated, thereby realizing efficient heat dissipation and ensuring that the engine 1 always operates stably in a suitable temperature environment.

[0036] Working principle: In the process of using the engine cover with pressure resistance, when the cover 2 needs to be installed, first pick up the cover 2 and align the bottom end of the support column 8 with the position of the connecting hole of the engine 1, then put down the cover 2 so that the support column 8 enters the inside of the connecting hole of the engine 1. At this time, the inner wall of the engine 1 extrudes the support strip 10 to make it shrink to the inside of the support column 8. When the cover 2 is installed in place, the support strip 10 is tightly attached to the inner wall of the connecting hole of the engine 1 under the support of the spring two 12, thereby completing the installation of the cover 2. When the engine 1 generates heat during operation, a part of the heat is absorbed by the heat dissipation fins one 13 and the heat dissipation fins two 14 and then guided to the inside of the cover 2. This part of the heat will be carried out by the air in the process of automobile operation, part of the external air enters from the air inlet 17, flows through the air duct 19 and flows out from the air outlet 18, and the remaining part of the heat is discharged from the inside of the base 1 through the ventilation net 16.
