Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts and components, in particular to an engine suspension inner skeleton structure. Background Art

[0002] The engine suspension inner frame is a support structure used to suspend and install the engine, and can cushion and reduce shock after the engine is started. If an abnormal noise is heard from the engine after a car has been running for a long time, it is usually because the suspension inner frame is damaged, making it unable to continue to cushion the vibration of the engine, thus causing the abnormal noise.

[0003] At present, most of the engine suspension inner frames are generally assembled with the suspension outer frames during installation. The suspension outer frames are connected to the vehicle body, and then the suspension inner frames are installed inside the outer frames. Finally, the engine is installed between multiple inner frames, and the vibration of the engine is buffered by the shock-absorbing and buffering structure between the inner frames and the outer frames. However, it is found during operation that the inner frames are prone to wear or damage after being used for a period of time, causing abnormal noise. Therefore, the inner frames need to be removed from the outer frames for replacement. However, most of the current installation structures between the inner frames and the outer frames are relatively complicated, and it is not convenient to remove the inner frames from the outer frames for replacement, which makes it inconvenient to repair and replace them later. Therefore, it is necessary to design an engine suspension inner frame structure that is easy to install and disassemble to solve the above problems. Utility Model Content
