Description

Technical Field

[0001] This invention relates to the field of automotive mechanical structure technology, and more specifically, to a lightweight automotive front-end module framework. Background Technology

[0002] Aluminum alloys, due to their low density, high specific strength, good corrosion resistance, and high temperature resistance, have become a core material for automotive lightweighting. The front-end module of the car utilizes an aluminum alloy extrusion design, which, while ensuring structural strength, improves the high-temperature resistance of the front-end module, reduces vehicle weight, enhances fuel economy, reduces space utilization, increases the design freedom of surrounding components, and simultaneously meets the requirements of automotive collision safety and assembly compatibility.

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] like Figures 1 to 6 As shown, this embodiment of the invention provides a lightweight front-end module frame for automobiles, including: a main crossbeam 1, a front bumper mounting bracket 2, a headlight mounting bracket 3, a hood lock mounting bracket 4, and a buffer block mounting bracket 5.

[0033] The front bumper mounting brackets 2 are evenly spaced at the front end of the main crossbeam 1. The headlight mounting brackets 3 are respectively located at both ends of the main crossbeam 1 and on both sides of the front bumper mounting brackets 2. The hood lock mounting brackets 4 are located at the center of the top of the main crossbeam 1. The buffer block mounting brackets 5 are located on both sides of the top of the main crossbeam 1.

[0034] The main crossbeam 1 includes two first connecting plates 11 and two second connecting plates 12. The two ends of the two first connecting plates 11 are respectively connected to the two ends of the two second connecting plates 12 to form a rectangular structure. The thickness of the first connecting plate 11 is greater than the thickness of the second connecting plate 12.

[0035] Specifically, by making the thickness of the first connecting plate 11 greater than the thickness of the second connecting plate 12, an unequal material thickness design is adopted to reduce weight while improving lock strength.

[0036] The front bumper mounting bracket 2 includes a first connecting post 21 and a second connecting post 22. The first end of the first connecting post 21 is connected to the first connecting plate 11, and the second end of the first connecting post 21 is connected to the first connecting post 22. The wall thickness of the first connecting post 21 is greater than the wall thickness of the second connecting post 22.

[0037] Specifically, the wall thickness of the first connecting post 21 is greater than that of the second connecting post 22, which further improves the collapsibility in case of impact through the structure of unequal material thickness.

[0038] This invention features front bumper mounting brackets 2 evenly spaced at the front end of the main crossbeam 1, headlight mounting brackets 3 positioned at both ends of the main crossbeam 1 and located on either side of the front bumper mounting brackets 2, hood lock mounting brackets 4 positioned at the center of the top of the main crossbeam 1, and buffer block mounting brackets 5 located on either side of the top of the main crossbeam 1. Two first connecting plates 11 are connected at both ends to two second connecting plates 12 to form a rectangular structure, with the thickness of the first connecting plate 11 greater than that of the second connecting plate 12. The first end of a first connecting post 21 is connected to the first connecting plate 11, and the second end of the first connecting post 21 is connected to the first connecting post 22. The wall thickness of the first connecting post 21 is greater than that of the second connecting post 22. This invention occupies less design space within a limited area, increases the design freedom of surrounding groups, and improves front-end collision performance, solving the problems of large design space and poor collision performance in existing technologies.

[0039] In one embodiment of the lightweight front-end module frame of the present invention, the main crossbeam 1, the front bumper mounting bracket 2, the headlight mounting bracket 3, the hood lock mounting bracket 4, and the buffer block mounting bracket 5 are all made of 6-series aluminum alloy. This configuration reduces the weight of the lightweight front-end module frame, effectively reduces fuel consumption or energy loss, improves driving response speed and safety in emergency situations, and can more effectively absorb and disperse energy during a collision, ensuring the safety of occupants.

[0040] In one embodiment of the automotive lightweight front-end module framework of the present invention, such as Figure 3 As shown, the front bumper mounting bracket 2, the headlight mounting bracket 3, and the buffer block mounting bracket 5 are all made of aluminum extrusion process. The side wall 32 of the second connecting column 22 is recessed inward. This setting forms a linear structure with unequal material thickness, increases the freedom of design of the surrounding grouping, and improves the front collision performance.

[0041] In one embodiment of the automotive lightweight front-end module framework of the present invention, such as Figure 1 and Figure 2 As shown, the main crossbeam 1 is formed by extrusion bending process, which achieves a balance of strength, lightweight, cost and efficiency, and avoids the springback problem of traditional stamping process; the thickness of the first connecting plate 11 is 2.0mm, and the thickness of the second connecting plate 12 is 1.5mm.

[0042] In one embodiment of the automotive lightweight front-end module framework of the present invention, such as Figure 4As shown, the headlight mounting bracket 3 includes a fixing sleeve 31 and two support plates 34. The two support plates 34 are connected in a cross shape, and the two ends of the support plates 34 are respectively connected to the inner wall of the fixing sleeve 31. The bottom of the fixing sleeve 31 is connected to the first connecting plate 11. The thickness of the side wall 32 of the fixing sleeve 31 is less than the thickness of the bottom wall 33 of the fixing sleeve 31.

[0043] This invention provides support for the fixed sleeve 31 by connecting two support plates 34 in a cross shape and connecting the two ends of the support plates 34 to the inner wall of the fixed sleeve 31, thereby improving the structural strength of the headlight mounting bracket 3. The bottom of the fixed sleeve 31 is connected to the first connecting plate 11, so that the thickness of the side wall 32 of the fixed sleeve 31 is less than the thickness of the bottom wall 33 of the fixed sleeve 31, thereby reducing the weight of the headlight mounting bracket 3 and meeting the requirements of lightweight design.

[0044] In one embodiment of the automotive lightweight front-end module framework of the present invention, such as Figure 5 As shown, the front cover lock mounting bracket 4 includes a first fixing plate 41 and an annular mounting plate 42. The annular mounting plate 42 is respectively disposed at both ends of the first fixing plate 41. The annular mounting plate 42 is connected to the second connecting plate 12. The thickness of the annular mounting plate 42 is greater than the thickness of the first fixing plate 41.

[0045] The present invention sets annular mounting plates 42 at both ends of a first fixing plate 41, and connects the annular mounting plates 42 to a second connecting plate 12. The thickness of the annular mounting plates 42 is greater than the thickness of the first fixing plate 41. The thickness of the connection part between the front cover lock mounting bracket 4 and the second connecting plate 12 is set to be greater than the thickness of other structures, which improves the stability of installation, ensures structural strength, and reduces the weight of the front cover lock mounting bracket 4.

[0046] Furthermore, the front cover lock mounting bracket 4 is made of aluminum stamping process, the thickness of the annular mounting plate 42 is 6.5mm, and the thickness of the first fixing plate 41 is 3.0mm.

[0047] In one embodiment of the automotive lightweight front-end module framework of the present invention, such as Figure 6 As shown, the buffer block mounting bracket 5 includes a second fixing plate 51 and a fixing frame 52. The second fixing plate 51 is provided with mounting holes 53 for mounting buffer blocks. The fixing frame 52 is mounted on the second connecting plate 12 and is connected to the second fixing plate 51. The thickness of the second fixing plate 51 is 1.5mm.

[0048] The present invention improves head impact performance by mounting the fixing frame 52 on the second connecting plate 12, thereby connecting the fixing frame 52 to the second fixing plate 51, while reducing the weight of the buffer block mounting bracket 5.

[0049] This invention occupies less design space within a limited space, increases the design freedom of the surrounding groups, and improves the front collision performance, thus solving the problems of large design space and poor collision performance in the prior art.
