Description

Technical field:

[0001] The utility model belongs to the technical field of automobile front-end frames, in particular to a front-end frame with a sheet metal crossbeam embedded therein. Background technology:

[0002] Currently, automotive plastic front-end frames are structural components made of plastic materials. They primarily support and protect key front-end components such as the engine, radiator, and headlights. Located within the engine compartment, they also enhance vehicle rigidity, absorb energy, reduce weight, and mitigate noise and vibration. However, with the widespread adoption of all-plastic front-end frames, various specifications have become more standardized, and performance requirements have become increasingly stringent. This is particularly true in areas not directly connected to vehicle components, where support strength is low. Relying solely on the inherent rigidity of the plastic material is increasingly unable to meet the required strength requirements. Summary of the invention:

[0003] The purpose of the utility model is to provide a front-end frame with an embedded sheet metal beam, which is arranged on the front-end frame by means of the inner cavity of the sheet metal beam to effectively increase the local support strength of the front-end frame, and at the same time reasonably optimize the structure of the sheet metal beam. Through the structural design coordination of the injection through hole and the positioning through hole, the sheet metal beam can be accurately positioned in the injection mold and can be effectively wrapped and fixed by the wrapping frame.

[0004] The utility model is achieved in this way:

[0005] A front-end frame with a sheet metal beam embedded therein comprises a front-end frame body, the front-end frame body comprising a sheet metal beam and a wrapping frame which is injection-molded integrally on the sheet metal beam and wraps the sheet metal beam. The sheet metal beam is provided with a plurality of injection through-holes, through which hot-melt injection molding raw materials flow to form circulation channels for the wrapping frame. Positioning through-holes are provided at both ends of the sheet metal beam, which are used to penetrate and cooperate with the positioning columns of the injection mold to fix the position of the sheet metal beam on the injection mold.

[0006] In the above-mentioned front-end frame with a sheet metal cross beam embedded therein, the wrapping frame has a frame-shaped bracket portion for connecting and cooperating with the vehicle radiator, and the sheet metal cross beam is located within the top horizontal edge of the frame-shaped bracket portion.

[0007] In the above-mentioned front-end frame with a sheet metal beam embedded therein, the cross-section of the sheet metal beam is an L-shaped structure, the L-shaped short end of the sheet metal beam is arranged along the top surface of the frame-shaped bracket part, and the L-shaped long end of the sheet metal beam is arranged along the front end surface of the frame-shaped bracket part.

[0008] In the above-mentioned front end frame with a sheet metal beam embedded therein, the frame-shaped bracket portion forms a plurality of reinforcing rib structures between the L-shaped short end and the long end of the sheet metal beam, and the reinforcing rib structures are arranged along the length direction of the sheet metal beam.

[0009] In the above-mentioned front-end frame with a sheet metal cross beam embedded therein, both sides of the frame-shaped bracket portion extend outwards to form reinforced side portions for fixed connection with the vehicle.

[0010] In the above-mentioned front end frame embedded with the sheet metal cross beam, the injection-molded through holes are evenly distributed on the sheet metal cross beam.

[0011] The outstanding advantages of the utility model compared with the prior art are:

[0012] The utility model has a simple structure, reasonable design and can effectively meet the design strength requirements. It is arranged on the front end frame by means of the inner cavity of the sheet metal beam to effectively increase the local support strength of the front end frame, and at the same time reasonably optimizes the structure of the sheet metal beam. Through the structural design coordination of the injection through hole and the positioning through hole, the sheet metal beam can be accurately positioned in the injection mold and can be effectively wrapped and fixed by the wrapping frame.
