[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", and "setting" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood in specific circumstances. In addition, in the description of the utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. are based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model.

[0022] See also Figure 1-5 The utility model provides an embodiment: a pressure-resistant engine thermal insulation pad, comprising a thermal insulation pad body 1, the thermal insulation pad body 1 comprises a middle thermal insulation layer 101 and two non-woven fabric layers 102 respectively arranged at both ends of the thermal insulation layer 101, the thermal insulation layer 101 can be specifically made of a composite of PP material and PET material, the non-woven fabric layers 102 are hot-pressed and fixed on both sides of the thermal insulation layer 101, and have good thermal insulation and sound absorption effects;

[0023] A limiting frame 2 is arranged on the inner side of the thermal insulation pad body 1, and the limiting frame 2 includes a frame 201 arranged at the edge of the thermal insulation pad body 1 and a reinforcing rib 202 arranged on the inner side of the frame 201. The limiting frame 2 is fixedly connected to the engine cover through a plurality of fixing buckles 3. A plurality of through holes for accommodating the fixing buckles 3 to pass through are arranged on the edge of the thermal insulation pad body 1. A plurality of mounting holes 2011 corresponding to the fixing buckles 3 are arranged on the frame 201. The limiting frame 2 presses the thermal insulation pad body 1 against the inner side wall of the engine cover to improve the pressure resistance of the thermal insulation pad body 1. At the same time, when individual fixing buckles 3 become loose and fall off, the thermal insulation pad body 1 will not become loose and fall off. At the same time, when the thermal insulation pad body 1 is damaged, the limiting frame 2 can be recycled.

[0024] The fixing buckle 3 includes a limit plate 301, a plurality of plug rods 302 fixed to the bottom end of the limit plate 301 in a circumferential array, and a clamping block 303 fixed to the bottom end of the plug rod 302. A clamping groove matching the fixing buckle 3 is provided on the inner side of the hood. Specifically, the size of the limit plate 301 is larger than the size of the mounting hole 2011. Figure 4 The opening size of the engine cover slot is smaller than the internal size. When the card block 303 is plugged in, it first undergoes elastic deformation, passes through the opening and then opens, so that the card block 303 abuts against the inner wall of the opening to achieve its installation and fixation. In this embodiment, the number of the plug-in rods 302 is set to two, and it can also be set to other numbers as needed;

[0025] The lever 304 is fixed to the inner side of the plug rod 302, and a through hole 3011 is set in the middle of the limit plate 301 to accommodate the lever 304 to move toward the middle. The top of the lever 304 passes through the through hole 3011 and extends to the outside of the limit plate 301. In this embodiment, the plug rod 302 is an L-shaped rod, and its bottom end is connected and fixed to the bottom end of the plug rod 302. In order to improve the driving effect of the lever 304, a plurality of reinforcing rods can be horizontally arranged on the connecting surface of the plug rod 302 and the lever 304 to prevent the lever 304 from being deformed when the lever 304 is toggled, and the two clamping blocks 303 cannot be driven to move toward the middle to realize the disassembly and assembly of the fixed buckle 3.

[0026] In one embodiment, the fixing buckle 3 further includes a spring 305 for pushing the two relative levers 304 to move toward both sides, which can push the levers 304 and the plug-in rods 302 to open toward both sides at the same time to abut against the opening of the engine cover slot.

[0027] Working principle: During installation, place the limit frame 2 on the inner side of the insulation pad body 1, the insulation pad body 1 abuts against the inner wall of the hood, and the fixing buckle 3 is directly inserted into the installation hole 2011, and then passes through the through hole on the insulation pad body 1 to be fixed with the hood. When the insulation pad body 1 needs to be disassembled, directly pinch the two levers 304 toward the middle to drive the two plug-in rods 302 to undergo elastic deformation, and the two card blocks 303 move toward the middle and separate from the card slots on the hood, and then pull out the fixing buckle 3.
