Description

Technical Field

[0009]

[0001] The present invention belongs to the field of automobiles, and particularly relates to an automobile front-end module structure. Background Art

[0002] With the rapid development of the automobile industry, the non-bearing body, as a traditional body structure, while constantly changing with the needs of technology and the market, also needs to constantly face new design challenges.

[0003] The automobile front-end module is an important part of the front body frame. Its main functions are to provide the bearing and installation function for the cooling module and important parts for pedestrian protection. In addition, it also provides installation points for the front bumper beam and the outer surface skin, forming a closed structure at the front of the vehicle body, which plays an important role in aspects such as human comfort and safety. Therefore, it is very meaningful to design a front-end structure that meets various performance indicators and has a high comprehensive cost performance under the harsh boundary conditions of the non-bearing body itself.

[0004] The existing designs are basically the design structures of traditional bearing bodies. Generally, the upper radiator crossbeam, the lower radiator crossbeam, the left vertical plate, and the right vertical plate form a "square" structure. This structure has the disadvantages of low structural strength, poor protection of driver safety and engine compartment components, and high stamping costs due to the large number of parts. Summary of the Invention

[0005] In view of the above problems, the present invention proposes an automobile front-end module structure, which includes a first vertical beam and a second vertical beam arranged at intervals;

[0006] One end of the first vertical beam and the second vertical beam is connected to a first crossbeam, and the other end is connected to a second crossbeam; a protection crossbeam is installed between the first crossbeam and the second crossbeam, and both ends of the protection crossbeam are respectively connected to the first vertical beam and the second vertical beam;

[0007] Both ends of the first crossbeam and the second crossbeam are bent and extended in the same direction.

[0008] Further, the first vertical beam, the second vertical beam, the first crossbeam, the second crossbeam, and the protection crossbeam are connected to form a "曰" structure.

[0009] Further, the protection crossbeam protrudes away from the ends of the first crossbeam and the second crossbeam.

[0010] Further, the automobile front-end module structure further includes a first connecting plate, and the first connecting plate is connected to the end of the first crossbeam and is connected to the vehicle body module.

[0011] Furthermore, the first connecting plate is an "L" shaped plate, which includes a first plate and a second plate. The first plate has a first folded edge and the second plate has a second folded edge, and the first folded edge and the second folded edge are fixedly connected.

[0012] Furthermore, the vehicle front-end module structure also includes a first mounting device and a second connecting plate, which are respectively mounted on opposite outer surfaces at the ends of the second crossbeam.

[0013] Furthermore, both the first mounting device and the second connecting plate are "L" shaped plates. The first mounting device includes a first plate and a second plate, and the second connecting plate includes a third plate and a fourth plate. The first plate and the third plate are respectively mounted on opposite outer surfaces at the ends of the second crossbeam, and the second plate and the fourth plate overlap.

[0014] Furthermore, the first plate, the third plate, and the second crossbeam form a space with a cavity.

[0015] Furthermore, the vehicle front-end module structure also includes a crossbeam connecting plate, which is installed on the outer surface of both ends of the second crossbeam. The crossbeam connecting plate is provided with connecting holes, which are connected to the vehicle body by bolts.

[0016] Furthermore, the crossbeam connecting plate is provided with reinforcing ribs.

[0017] Beneficial effects of this invention:

[0018] 1. The first and second crossbeams of the present invention are both bent and extended in the same direction to completely surround the cooling module, providing sufficient space for layout and installation operation; in the event of a collision, the engine compartment space is increased, protecting the components inside the compartment, lengthening the energy transfer path, and also protecting the safety of the driver.

[0019] 2. The first vertical beam, second vertical beam, first horizontal beam, second horizontal beam, and protective horizontal beam of the present invention are connected to form a "U"-shaped structure. This improves the rigidity requirements of the front module of the vehicle body and protects the cooling module from damage caused by external splashing objects.

[0020] 3. The protective beam of the present invention protrudes away from the ends of the first and second crossbeams to accommodate the dual-fan configuration of the cooling system. Therefore, the protective beam is bent towards the vehicle body to increase the internal layout space and meet the needs of different configurations.

[0021] 4. The first connecting plate of the present invention is an "L" shaped plate, which includes a first plate and a second plate. The first plate has a first folded edge and the second plate has a second folded edge. The first folded edge and the second folded edge are fixedly connected to form a semi-enclosed structure, which solves the problem of rigidity and strength of the parts.

[0022] 5. The first plate, the third plate, and the second crossbeam of the present invention form a space with a cavity, which improves the connection strength of the parts.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] refer to Figure 1 A front-end module structure for automobiles includes a first vertical beam 1 and a second vertical beam 2 arranged at intervals. One end of the first vertical beam 1 and the second vertical beam 2 are connected to a first horizontal beam 3, and the other end is connected to a second horizontal beam 4. A protective horizontal beam 5 is installed between the first horizontal beam 3 and the second horizontal beam 4, and both ends of the protective horizontal beam 5 are connected to the first vertical beam 1 and the second vertical beam 2 respectively.

[0035] Both ends of the first crossbeam 3 and the second crossbeam 4 are bent and extended in the same direction; the protective crossbeam 5 protrudes away from the ends of the first crossbeam 3 and the second crossbeam 4.

[0036] Specifically, the first vertical beam 1, the second vertical beam 2, the first cross beam 3, the second cross beam 4, and the protection cross beam 5 all adopt pipe beams. The pipe beam structure has a simple process, and the shape can be directly bent according to design requirements, avoiding the need for multi-step forming of the mold like the traditional sheet metal structure. The mold cost is high; the mold cycle is long, and the mold modification cycle is long in the later stage, resulting in a large demand for inventory and increased stocking pressure. The pipe beam structure avoids the above disadvantages and optimizes and improves the manufacturing efficiency. Moreover, in this structural form, the main structure can be reused, and the protection cross beam 5 can be flexibly changed according to the position and shape, which not only meets the platformization but also ensures the flexibility in the layout of different vehicle models. Specifically, the first vertical beam 1 and the second vertical beam 2 are symmetric left and right. At the symmetric positions of the first vertical beam 1 and the second vertical beam 2, there are respectively a first mounting hole 101 and a second mounting hole 201. By adjusting the up and down positions of the protection cross beam 5 and then installing it into different first mounting holes 101 and second mounting holes 201, various different vehicle model requirements can be met.

[0037] Furthermore, the first vertical beam 1, the second vertical beam 2, the first cross beam 3, the second cross beam 4, and the protection cross beam 5 are connected to form a "曰" - shaped structure. (Refer to Figure 2 ), which improves the stiffness requirements of the front body module; protects the cooling module from being damaged by foreign flying objects (the cooling module is located in the bending direction of the first cross beam 3 and the second cross beam 4); thus preventing the cooling module from being damaged by impact and causing parts to fly and injure pedestrians, meeting the pedestrian protection requirements for the thighs and calves. The structural design of the present invention is reliable. By adopting a horizontal and vertical frame structure (the first vertical beam 1, the second vertical beam 2, the first cross beam 3, the second cross beam 4, and the protection cross beam 5 are connected to form a "曰" structure), it can not only meet the requirements of NVH (Noise, Vibration, Harshness), strength fatigue, safety, layout, process, etc., but also significantly reduce the number of parts compared with the traditional structure, reducing the production and process complexity, accelerating the production beat, reducing costs, and enhancing the product competitiveness.

[0038] The design of the present invention is ingenious and beautiful. According to the performance and functional requirements, the "曰" structure is adopted, making the front end module structure more stable, with excellent performance and low cost.

[0039] In the present invention, the first vertical beam 1, the second vertical beam 2, the first cross beam 3, the second cross beam 4, and the protection cross beam 5 are connected to form a 3 - horizontal and 2 - vertical frame structure. A total of 12 bolts on the left and right are used to connect the front end module to the front part of the vehicle body (connected to the front part of the vehicle body through the first connecting plate 6, the first mounting device 7, the second connecting plate 8, and the cross beam connecting plate 11).

[0040] The first cross beam 3 and the second cross beam 4 are in a "U" - shaped structure. Specifically, the first cross beam 3 and the second cross beam 4 of the present invention both extend 170 mm towards the vehicle body direction, as shown in Figure 3 As shown, it completely surrounds the cooling module, providing ample space for layout and installation; in the event of a collision, it increases the engine compartment space, protects the components inside the compartment, lengthens the energy transfer path, and also protects the driver's safety.

[0041] Furthermore, the protective crossbeam 5 is provided with weight-reduction holes 501 and third mounting holes 502, with the weight-reduction holes 501 located among several third mounting holes 502. To accommodate the dual-fan configuration of the cooling system, the protective crossbeam 5 is bent towards the vehicle body to increase internal space and meet the needs of different configurations. The weight-reduction holes 501 reduce the vehicle's weight while meeting the space requirements for grille assembly; the multiple third mounting holes 502 provide mounting positions for wiring harnesses, exterior trim, and grille assembly.

[0042] The automotive front-end module structure also includes a first connecting plate 6, which is connected to the end of the first crossbeam 3 and to the body module.

[0043] Specifically, the two first connecting plates 6 are symmetrical about the first crossbeam 3, and the two first connecting plates 6 are respectively connected to the upper part of the front module structure of the car body by two bolts.

[0044] The first connecting plate 6 is an "L" shaped plate. The first connecting plate 6 includes a first plate and a second plate. The first plate has a first folded edge and the second plate has a second folded edge. The first folded edge and the second folded edge are fixedly connected.

[0045] Specifically, the first connecting plate 6 is an "L"-shaped plate, which is formed by bending a piece of sheet metal and then folding its edges (forming a first fold and a second fold). The first and second folds are then welded together, achieving self-welding and forming a semi-enclosed structure, thus solving the rigidity and strength problems of the parts (see...). Figure 7 ).

[0046] The automotive front-end module structure also includes a first mounting device 7 and a second connecting plate 8, which are respectively mounted on opposite outer surfaces at the ends of the second crossbeam 4.

[0047] In this invention, the first mounting device 7 and the second connecting plate 8 are both "L" shaped plates. The first mounting device 7 includes a first plate and a second plate, and the second connecting plate 8 includes a third plate and a fourth plate. The first plate and the third plate are respectively mounted on the opposite outer surfaces of the ends of the second crossbeam 4, and the second plate and the fourth plate overlap.

[0048] The first plate, the third plate, and the second crossbeam 4 form a space with a cavity (i.e., forming a box shape).

[0049] Specifically, the two first mounting devices 7 are symmetrical about the second crossbeam 4, and the two first mounting devices 7 are respectively connected to the lower part of the front-end module structure of the vehicle body by three bolts; the two second connecting plates 8 are symmetrical about the second crossbeam 4, and the two second connecting plates 8 are connected to the lower part of the front-end module structure of the vehicle body by three bolts (the overlapping parts of the first mounting devices 7 and the second connecting plates 8 share three bolts); through the connection of the two first connecting plates 6, the first mounting devices 7 and the second connecting plates 8 to the front of the vehicle body, the front-end module structure of the vehicle body is connected to the vehicle body to form a closed structure, realizing the collision safety energy transfer path (that is, when the front-end module structure of the vehicle collides with the vehicle body, the collision force is transferred to the vehicle body along the first connecting plates 6, the first mounting devices 7 and the second connecting plates 8, thus realizing the collision safety energy transfer).

[0050] like Figure 4 As shown, the first plate and the third plate are welded together to form a box shape, which improves the connection strength of the parts. The first welding positioning hole 701 is the main welding positioning hole; the second welding positioning hole 702 is the auxiliary welding positioning hole, which is used to fix the relative position between the first mounting device 7 and the second connecting plate 8; the elongated hole 703 is used to connect the second connecting plate 8, that is, the first mounting device 7 and the second connecting plate are welded through the elongated hole 703; the fourth mounting hole 704 is used for the cooling module mounting hole. The fourth mounting hole 704 adopts a flanged hole to increase the rigidity of the opening position, such as... Figure 5 As shown; in order to enhance the rigidity and strength requirements of the cooling module, the overall structure is bolted to the lower part of the vehicle body, with two sets of first mounting devices 7 and a symmetrical design, so that the vehicle body forms a solid closed structure.

[0051] In the above embodiments, another optional implementation is that the vehicle front-end module structure further includes a crossbeam connecting plate 11, which is installed on the outer surfaces of both ends of the second crossbeam 4. The crossbeam connecting plate 11 is provided with connecting holes 1104, which are connected to the vehicle body by bolts.

[0052] The crossbeam connecting plate 11 is provided with reinforcing ribs 1105.

[0053] Specifically, refer to Figure 6 The present invention includes two crossbeam connecting plates 11, which are symmetrically installed about a second crossbeam 4. Each crossbeam connecting plate 11 is provided with a first positioning hole 1101, a second positioning hole 1102, a wire harness mounting hole 1103, and a connecting hole 1104. The first positioning hole 1101 and the second positioning hole 1102 are used to assist in positioning the crossbeam connecting plates 11. The wire harness mounting hole 1103 is used for wire harness installation. The connecting hole 1104 is connected to the vehicle body via bolts. Reinforcing ribs 1105 are used to strengthen the crossbeam connecting plates 11, increasing the rigidity of the parts themselves. Figure 6 As shown. The overall structure solves the problem of multiple paths for the transfer of collision energy and also protects the cooling module from damage.

[0054] The front-end module features an optimized structural design and simplified processes, taking into account various performance requirements and diverse iterative changes, thus solving the problems of numerous parts, high costs, and complex processes.

[0055] This non-load-bearing front-end module structure is simple and aesthetically pleasing, with continuous force transmission. It meets the performance requirements of vehicle structure durability, NVH and safety while also taking cost into consideration.

[0056] In another embodiment, two speaker mounting brackets 12 are respectively installed on the outer sides of the first vertical beam 1 and the second vertical beam 2, and the speaker mounting brackets 12 are used to install subwoofers. Two condenser mounting brackets 9 are respectively installed on the inner sides of both ends of the first crossbeam 3, and the two condenser mounting brackets 9 are respectively connected to the vehicle's cooling module; the cooling module includes the vehicle's condenser. A second protective bracket 14 is installed on the upper surface of the first crossbeam 3, and the second protective bracket 14 is located in the middle of the first crossbeam 3, for installing the front bumper of the vehicle.

[0057] Two first protective brackets 10 are installed on the upper surface of the first crossbeam 3. The two first protective brackets 10 are located between the second protective bracket 14 and the two condenser mounting brackets 9, respectively, for installing the front bumper of the vehicle.

[0058] Furthermore, two skin brackets 13 are installed on the upper surface of the first crossbeam 3, and the two skin brackets 13 are located between the second protective bracket 14 and the two first protective brackets 10; for installing the outer shell of the vehicle.

[0059] Furthermore, two lamp brackets 15 are symmetrically installed on the outer sides of the first vertical beam 1 and the second vertical beam 2. The lamp brackets 15 are used to install the vehicle's headlights.

[0060] The design layout and process of this invention are reasonable and easy to manufacture. The main frame beam structure is suitable for mass production, minimizing manufacturing and production costs.
