Description

Engine support assembly of new energy hybrid electric vehicle Technical Field The invention relates to the technical field of new energy hybrid electric vehicles, in particular to an engine bracket assembly of a new energy hybrid electric vehicle. Background New energy Hybrid Electric Vehicles (HEVs) are becoming an important development direction of the market due to their excellent fuel economy and environmental performance. The automobile is innovatively provided with an engine and a motor at the same time, and the two power sources can be flexibly switched according to different driving working conditions so as to realize optimal power output and energy consumption control. However, there are a series of problems to be solved in the engine support system of the hybrid vehicle in the prior art. In the actual running process, the engine and the motor are frequently switched, wherein the engine can generate larger vibration when being started. To mitigate the impact of such vibrations on the overall performance of the vehicle, existing engine mounts are typically equipped with engine mounts as vibration dampening devices. However, due to the frequent starting of the engine, the rubber feet of the engine bear strong vibration impact at the starting moment for a long time, so that the rubber feet are extremely easy to fatigue and age. The aged rubber foot rubber can be hardened, so that the damping effect of the rubber foot is reduced, the service life of the rubber foot is shortened, and the maintenance cost and the potential safety hazard are increased. On the other hand, the elasticity of the rubber feet of the existing engine is fixed and not adjustable. When the motor works alone and the engine is in a stop state, the engine rubber feet cannot lock the engine completely and firmly. In the running process of the vehicle, the engine cannot be effectively fixed to shake, so that the shake amplitude of the whole hybrid electric vehicle is increased. This not only seriously affects the stability of the vehicle running, but also makes the driver unable to fully enjoy the smooth driving experience brought by the motor, and reduces the riding comfort. In view of the foregoing, it has been difficult for existing engine mount assemblies to meet the ever-increasing performance demands of hybrid vehicles. In order to improve the overall quality and user experience of the hybrid electric vehicle, a brand new engine bracket assembly of the new energy hybrid electric vehicle is urgently needed to be provided, so that the technical problem is effectively solved, and the requirements of complex and variable working conditions of the hybrid electric vehicle are met. Therefore, an engine bracket assembly of a new energy hybrid electric vehicle is provided. Disclosure of Invention The invention aims to provide an engine bracket assembly of a new energy hybrid electric vehicle, which solves the problems that rubber foot fittings in the existing engine bracket are difficult to adapt to the requirements of variable working conditions of the hybrid electric vehicle by arranging a rubber foot assembly of an engine on the engine bracket and enabling the hardness of the rubber foot of the engine to be adjustable. In order to achieve the above purpose, the present invention provides the following technical solutions: the utility model provides a new forms of energy hybrid vehicle's engine support assembly, includes the support body, be provided with a plurality of bolt holes on the support body, the bolt hole is used for with support body fixed connection on hybrid vehicle's frame, be provided with two damper on the support body, damper all includes the shell, shell fixed connection is on the support body, shell open-top and at inside formation columniform storage chamber, storage chamber top is provided with the soft rubber plate, soft rubber plate seals storage chamber top, be provided with the connecting bolt that is used for being connected with the engine in the middle of the soft rubber plate, connecting bolt passes the soft rubber plate and stretches into the storage intracavity portion, be glued between connecting bolt and the soft rubber plate, and ensure the leakproofness of connection, the inside packing of storage intracavity portion has magnetorheological fluid, the inside slidable mounting that still has the resistance piece of storage chamber, the one end that resistance piece and connecting bolt stretched into the storage chamber is articulated through the spherical hinge, be provided with reset spring between resistance piece and the storage chamber bottom, storage chamber bottom fixed mounting has the electro-magnet, but support control assembly and motor control assembly, but electric hybrid vehicle control assembly and electric property connection.
