Description

Technical Field

[0001] This application relates to the technical field of automotive parts, and in particular to an automotive engine support frame. Background Art

[0002] When the engine is working, it will drive the vehicle body to vibrate. In order to reduce the impact of the engine, a suspension bracket assembly is used to connect the frame and the engine. The suspension bracket assembly includes a connecting frame and a buffer frame. One end of the connecting frame is fixedly connected to the engine, and the other end is mostly connected to the frame by a hinge. The buffer frame is fixed on the frame and is located between the hinge end of the connecting frame and the engine. When the connecting frame is displaced, the buffer frame buffers and absorbs energy from the connecting frame to achieve the purpose of reducing the vehicle body vibration. A buffer medium is provided on the periphery of the connecting frame for buffering and energy absorption. The buffer medium is generally a rubber or other elastic buffer-made surrounding profile, and this profile is a consumable.

[0003] Most of the existing engine structures are integrally cast from metal materials. When ensuring the connection strength and rigidity of the structure, the problem of vehicle weight also needs to be considered. Therefore, some weight-reducing holes or grooves are generally provided on the bracket structure. For example, a Chinese patent with the authorization announcement number CN207173285U and the publication date of April 3, 2018 discloses a left front bracket for engine support, including a base, a top frame, and a bracket connecting the base and the top frame to play a supporting role. A first weight-reducing hole is opened on the back side of the base. First arc-shaped connecting segments are provided on both sides and the bottom of the base. Protrusions are formed between adjacent first arc-shaped connecting segments. Protrusions are also provided on both sides of the top of the base. Threaded holes are opened on the protrusions. The bracket is a gradually changing structure that is wider at the top and narrower at the bottom. A second weight-reducing through hole is opened at the center position of the bracket. The top frame is a stepped structure. The outer extending part of the top frame extending outside the bracket is higher than the connecting part between the top frame and the bracket, and the outer extending part and the connecting part are smoothly connected.

[0004] The above application uses the first weight-reducing hole and the second weight-reducing hole provided on the back of the base and the center of the bracket for weight reduction. However, both the base and the main body of the bracket are relatively thick metal plates, and the overall weight is large, which affects the use. Therefore, it is necessary to design a new automotive engine support frame with a lighter weight and guaranteed strength. Utility Model Content
