Description

Technical Field

[0001] The utility model relates to an automobile engine hood, in particular to an automobile engine hood with high efficiency and heat insulation, belonging to the technical field of automobile accessories. Background Art

[0002] In the prior art, for example, the utility model with publication number 202222147908.8 discloses a sound insulation and heat insulation structure for an automobile engine hood. In order to solve the problem of the inconvenience of replacing or cleaning the current heat insulation cotton pad, a detachable limiting mechanism is used to replace the traditional adhesive installation method. The rotating shaft is rotated by a hexagonal wrench, and the rotating shaft cooperates with the guide block through the rectangular groove to rotate the shaft sleeve, and the shaft sleeve drives the limiting plate, so that the limiting plate located on the outside of the cover body rotates to the inside of the cover body, and the five groups of limiting plates rotate at the same time to limit the cotton pad. Located in the cover body, the rotating shaft is squeezed by a hexagonal wrench, and the rotating shaft drives the guide block to move along the rectangular groove. At the same time, the rotating shaft squeezes the pressure plate through the receiving shaft, and the pressure plate moves along the groove. The pressure plate pushes a number of steel needles through the round hole to pierce the cotton pad, and the pressure plate will squeeze the spring sheet. At the same time, the guide block will stagger the rectangular groove and rotate the rotating shaft to make the guide block stuck in the shaft sleeve. Since a number of steel needles pierce the cotton pad, the cotton pad is firmly fixed in the cover body, and the limiting mechanism has a simple structure and is easy to operate, which is convenient for the staff to install and disassemble the cotton pad.

[0003] Similar to the above application, there are still some shortcomings:

[0004] The limiting mechanism can only press the heat insulation pad laid on the bottom of the engine hood to fit it on the engine hood, but the inner side of the engine hood cannot be protected, which affects the heat insulation effect during use. In addition, the contact area with the heat insulation cotton during the limiting and pressing process is limited, and the fixing effect is not good;

[0005] Therefore, a highly efficient heat-insulating automobile engine hood is designed to optimize the above-mentioned problems. Utility Model Content

In addition, the pressure strip can be used to press the edge of the heat insulation pad again, thereby increasing the contact area with the heat insulation pad and improving the installation stability.

The pressure plate 9 is in contact with the inner side of the thermal insulation pad 2, and the bottom end of the pressure plate 9 is in contact with the top of the pressure strip 3.

[0027] Local working principle: After the thermal insulation pad 2 is placed inside the engine hood 1, the pressure plate 9 is pulled outward, and the pressure plate 9 rotates with the rotating rod 6 as the axis. After the pressure plate 9 is rotated to the top of the thermal insulation pad 2, the pressure plate 9 is released, and the torsion spring 8 controls the automatic downward pressure of the pressure plate 9, which is tightly attached to the inner side of the thermal insulation pad 2.
