The suspension block is a supporting vibration isolation component connecting the engine and the vehicle body. It can isolate the transmission of engine vibration and noise into the vehicle compartment, significantly improving the comfort of the vehicle interior. However, it is also affected by the high temperature of the engine, which accelerates the aging of the internal rubber components and affects the service life of the suspension block.

[0003] For example, the engine suspension device with a heat insulation cover disclosed in the announcement number CN208544109U can retain the heat emitted by the engine body inside the suspension box by setting heat insulation cotton, thereby achieving the effect of heat preservation, so that the engine body can be kept at a normal working temperature, reducing the fuel consumption consumed by heating the engine body to the working temperature, and facilitating the use of users;

[0004] However, the above-mentioned engine suspension device with a heat insulation cover still has the following problems during actual use: although the heat insulation of the suspension block is achieved by the cover box, the existing suspension block needs to be connected to the frame and the engine during operation. The overall covering method is likely to affect the isolation of the engine vibration and occupy the space inside the engine compartment. The air cannot circulate between the engine suspension block and the heat insulation cover, and its ventilation and heat exchange capacity is reduced, so that the engine suspension block still has an overheating problem.
