[0002] The car engine support frame, also known as engine support or engine foot rubber (because its bottom usually has a rubber part), is an important component connecting the engine and the vehicle chassis. Its main functions include: supporting, which provides fixation and support for the engine, ensures the correct position of the engine in the vehicle, and can bear the weight of the engine and the vibration and torsion generated during operation; damping, which usually contains rubber or other elastic materials in the support frame, can absorb and reduce the vibration transmitted to the vehicle body during engine operation, thereby improving the ride comfort and reducing noise; protection, which can ensure that the engine is not easily displaced in the event of a collision, protecting the passengers in the cockpit; dynamic stability: the support frame helps to maintain the position stability of the engine, especially during acceleration, deceleration or turning, to ensure the normal operation of the power transmission system.

[0003] The connection points of the existing car engine support frame and the frame are usually located on the same plane, such as the commonly used three connections at equal intervals on the circumference. This design has defects. The multiple connection points located on the same plane cause stress concentration, increasing the risk of bracket fracture. Moreover, due to continuous vibration and torsion, the single plane connection method may cause the fatigue damage of the support structure to accelerate, so we propose a car engine support frame to solve this problem.
