Description

Front body beam module and assembly method thereof

The invention relates to a vehicle body front beam module and an assembly method thereof, and particularly relates to a vehicle body front beam module and an assembly method thereof, which can select different front beams according to different vehicle types.

In the current car body design, the front section structure (especially the structure before and after the firewall structure) is usually formed by direct stamping using large sheet metal parts. Therefore, different models have different front section structures.

However, because the front section structure is related to the front suspension structure, power system, front crash safety, brakes, steering and other components, that is, the front section of the car body shoulders the collision strength of the vehicle body, human factors engineering and other important Body design elements. Therefore, the design complexity of the front-end structure is higher than that of other parts, and the development cost accounts for about 60% of the whole. If the front section structure of the previously considered elements cannot be used in the development of new models, and each time a new front section structure is to be designed, the cost cannot be reduced either in design or in production.

The invention provides a front body beam module of a vehicle body, which can select different front girders in a modular design to match a costly firewall structure to correspond to different vehicle models, thereby effectively saving design and production costs.

The above described features and advantages of the invention will be apparent from the following description.

1 is a schematic view of a front body beam module of a vehicle body in accordance with an embodiment of the present invention. Figure 2 is a schematic exploded view of Figure 1. Figure 3 is a schematic illustration of the different perspectives of Figure 2. Referring to FIG. 1 to FIG. 3 , the front body beam module 100 of the present embodiment includes two front girders 110 , a firewall structure 120 , two structural reinforcement members 130 , and two suspension fixing members 140 .

Each front beam 110 includes a hollow first butt end 112. Each of the front girders 110 includes a notch 116 adjacent to the first butting end 112. In the present embodiment, the notch 116 is located at the bottom wall 114 of the front girders 110, but the position of the notch 116 is not limited thereto, as long as it is close to the first It is sufficient to dock the end portion 112. The firewall structure 120 includes two hollow second butt ends 122. In this embodiment, the two second butt end portions 122 are respectively sleeved on the two first butt end portions 112, and the two first butt end portions 112 are closely attached to the two second butt end portions 122 to make the two front portions The girders 110 are combined with the firewall structure 120.

In addition, the structural reinforcement 130 is disposed within the portion of the front girders 110 adjacent the first butted end 112 to increase the structural strength of the front girders 110 adjacent the firewall structure 120. In the present embodiment, the structural reinforcement 130 can enter the front girders 110 from the notches 116. The structural reinforcement 130 includes a recess 132.

The suspension fixing member 140 is disposed at a portion of the front beam 110 near the first butting end portion 112.

The notch 116 of the girders 110 and the recesses 132 that extend into the structural reinforcement 130 form a complete structure.

In general, the firewall structure 120 needs to consider the rigorous collision behavior, so the development cost is quite high. If each model re-develops the new firewall structure 120, the cost will be quite high. The front body beam module 100 of the embodiment splits the front structure of the vehicle body into the front beam 110 and the firewall structure 120, and is assembled in a modular manner. The firewall structure 120 can remain unchanged, and the designer can change according to different vehicles. The model only changes the length of the front girders 110 for modularization purposes. That is to say, the designer only needs to design a perfect firewall structure 120, and then select the appropriate length of the front girders 110 according to the desired vehicle type to assemble the required front girders module 100. Thus, the designer can utilize a sophisticated firewall structure 120 to extend a variety of vehicle models with different lengths of the front girders 110. Further explanation will be given below on how the vehicle body front beam module 100 is assembled and how to improve the structural strength in the vicinity of the joint.

In the present embodiment, the front beam 110 has a notch 116 near the first butted end 112, and the structural reinforcement 130 can enter the front beam 110 from the notch 116.

Finally, as shown in FIG. 6, the two suspension fixing members 140 are respectively disposed at positions where the two front beams 110 are close to the two first butt end portions 112 and are connected to the two structural reinforcement members 130 (step 250). In the present embodiment, a portion of the suspension fixture 140 will penetrate the front beam 110 from the notch 116 and into the groove 132 of the structural reinforcement 130. Thereafter, the two suspension fixing members 140 can be respectively fixed to the two front girders 110 by welding, and assembled into the vehicle body front girders module 100 as shown in FIG.

It is worth mentioning that the two suspension fixing members 140 can be first connected with the sub-frame (not shown), and then the two suspension fixing members 140 are fixed together with the sub-frame to the front beam 110, so that the sub-frame can The front frame 110 is coupled to the front beam 110 by a suspension fixture 140.

In summary, the front body beam module of the present invention divides the front beam and the firewall structure into different components for assembly, and the designer can select different front beams according to different vehicle types to match the same firewall structure to reduce design and manufacture. cost. In addition, the vehicle body front beam module of the present invention also increases the structural strength of the front beam near the firewall structure through the structural reinforcement. Alternatively, the suspension fixture can be attached to the front girders and structural reinforcements in combination with elements such as sub-frames to form a complete structure.
