Description
Technical Field
[0001] This application relates to the field of automotive parts technology, and more particularly to a front bumper for automobiles and an automobile. Background Technology
[0002] With increasingly stringent automotive safety regulations and pedestrian protection requirements, the energy absorption performance and pedestrian protection functions of the vehicle's front structure have become key areas of focus for the industry. Current bumper systems commonly employ rigid structures such as high-strength reinforcing brackets on the inside of the hood, high-strength reinforcing brackets above the hood lock area, and inner hood ring beams.
[0003] Such designs often place too much emphasis on rigid support and lack an efficient and controllable collision energy absorption mechanism, resulting in the impact force not being fully dissipated when a pedestrian-vehicle collision occurs, which can easily cause serious injury to the legs and upper body of pedestrians. At the same time, such reinforced structures do not fully consider the balance between material stiffness and energy absorption efficiency, which is not conducive to the goal of lightweighting and is also difficult to meet the requirements for pedestrian protection.

Detailed Implementation
[0021] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0022] The following description, with reference to the accompanying drawings, describes an embodiment of the automobile front bumper.
[0023] like Figures 1-6 As shown in the figure, the front bumper of the car in this application embodiment may include: a front bumper mechanism 100.
[0024] It should be noted that the specific structure of the front bumper mechanism 100 described in this embodiment is existing technology, so it will not be described in detail here.
[0025] The radiator grille mechanism 200 includes a radiator grille body 201, a radiator grille mounting plate 202, and a radiator grille bracket 203.
[0026] The radiator grille body 201 is connected to the front bumper mechanism 100 through the radiator grille mounting plate 202. The radiator grille bracket 203 is set on the radiator grille mounting plate 202. The radiator grille bracket 203 is arranged in an S-shaped structure. The radiator grille mounting plate 202 and the radiator grille bracket 203 together form an integrated forward collision composite energy absorption structure.
[0027] Specifically, the front bumper is installed on the target vehicle. During vehicle operation, when a collision occurs, the front bumper mechanism 100 first contacts and undergoes initial deformation to absorb some of the energy. Subsequently, the collision force is transferred to the integrated forward collision composite energy absorption structure.
[0028] The S-shaped radiator grille bracket 20323 undergoes stable and progressive buckling deformation (i.e., crushing) under axial pressure. Its unique S-shaped bending path greatly extends the path for force transmission and dissipation within the structure, thereby enabling more efficient and smooth absorption and dissipation of large amounts of collision kinetic energy through material plastic deformation. Compared to traditional straight-plate or simple reinforcing rib structures, the S-shaped structure provides higher energy absorption efficiency and superior cushioning performance.
[0029] The aforementioned structure significantly reduces the peak impact force and acceleration experienced by pedestrians' lower legs, pelvis, and other parts during a collision, greatly reducing the risk of serious injury to pedestrians during forward collisions and providing more effective protection for pedestrians. It also helps to reduce damage to components such as the vehicle's cooling system in low-speed collisions.
[0030] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, the mounting plate 202 and the radiator grille bracket 203 are made of ASA material. The density of ASA material is 1.06–1.09 g / cm³, the tensile modulus is 2000–2400 MPa, the flexural modulus is 2100–2500 MPa, and the elongation at break is between 20% and 40%.
[0031] It should be noted that the ASA material described in this embodiment may include acrylonitrile, styrene and acrylic rubber, and its specific production method has been disclosed in the prior art, so it will not be described in detail here.
[0032] Understandably, the density of ASA material is only 1.06–1.09 g / cm³, which is much lower than that of commonly used metal materials, resulting in a significant reduction in the weight of the entire composite energy-absorbing structure, which is beneficial for energy conservation and emission reduction in the whole vehicle.
[0033] Secondly, the structural stiffness and deformation controllability for impact energy absorption were optimized. The tensile and flexural moduli of the material are within a moderate range of 2000-2500 MPa, providing the necessary structural stiffness to stably support the radiator grille body 201 under normal conditions and effectively transfer loads in the initial stage of an impact. Combined with the S-shaped geometry, this modulus range ensures that the structure initiates stable, gradual buckling and crushing deformation after reaching the critical load, rather than undergoing rigid impact or instability.
[0034] Most importantly, it significantly enhances energy absorption efficiency and pedestrian protection performance. A 20%–40% elongation at break indicates that the ASA material possesses excellent ductility and toughness. During a collision, the S-shaped structure allows the material to undergo sufficient plastic deformation rather than brittle fracture during crushing deformation, more efficiently converting impact kinetic energy into deformation energy through its own extension. The combination of the ASA material and the S-shaped structure enables the "integrated forward-facing composite energy-absorbing structure" to undergo large deformations under controllable force levels, thus absorbing impact energy more smoothly and persistently, significantly reducing the peak force of impact on pedestrian legs, and further reducing the risk of pedestrian injury.
[0035] Furthermore, the use of the same ASA material to manufacture the radiator grille mounting plate 202 and the radiator grille bracket 203 ensures the material compatibility and mechanical properties of the connection interface between components. This facilitates the achievement of high-strength integrated connection through welding or bonding processes, avoiding connection failure or stress concentration caused by material differences. This ensures that the load is effectively transferred and dissipated in the composite structure according to the design path during a collision.
[0036] In summary, using ASA material with specific mechanical properties to manufacture the S-shaped radiator grille bracket 203 and mounting plate not only achieves lightweighting and improved durability, but more importantly, its moderate modulus and good ductility produce a significant synergistic effect with the S-shaped structural design, jointly optimizing the mechanical response of the energy-absorbing structure. This allows for more efficient and controllable energy absorption in collisions, providing a higher level of protection for pedestrians.
[0037] In one embodiment of this application, such as Figure 3 and Figure 5 As shown, the radiator grille bracket 203 includes a fixing plate 2033, two S-shaped short ribs 2031 of equal length, multiple S-shaped long ribs 2032 of equal length, and two connecting plates 2034.
[0038] The fixed plate 2033 is connected to the mounting plate 202 on the radiator grille; one end of the two S-shaped short ribs 2031 is connected, and one end of the multiple S-shaped long ribs 2032 is connected to the fixed plate 2033; the two S-shaped short ribs 2031 and the multiple S-shaped long ribs 2032 are respectively connected to the corresponding connecting plates 2034; with the front bumper mechanism 100 as the central axis, the two S-shaped short ribs 2031 and the multiple S-shaped long ribs 2032 are symmetrically arranged along the central axis.
[0039] It should be noted that the number of S-shaped long ribs 2032 of equal length described in this embodiment can be 12. In addition, the specific number of S-shaped long ribs 2032 can be determined according to the actual situation, depending on the installation space of the radiator grille bracket 203.
[0040] Understandably, the two short S-shaped ribs 2031 and the multiple long S-shaped ribs 2032, arranged symmetrically along the central axis, constitute a highly stable spatial stress-bearing structure. In the event of a frontal or offset collision, the impact load can be rapidly and evenly distributed to the multiple S-shaped ribs, effectively avoiding stress concentration and ensuring coordinated deformation of the entire energy-absorbing structure, thereby improving the stability and reliability of the energy absorption efficiency.
[0041] The radiator grille support structure 203, composed of a fixed plate 2033, long and short S-shaped ribs, and a connecting plate 2034, essentially constructs multiple parallel energy absorption paths with different geometric characteristics. The long S-shaped ribs 2032 serve as the main energy-absorbing elements, providing extended deformation strokes; the short S-shaped ribs 2031 enhance the stiffness and support of the central region of the structure. During a collision, these ribs achieve long-stroke, gradual energy absorption through the sequential buckling and flattening of their S-shaped bends. The excellent elongation at break (20%-40%) of the ASA material further ensures that the crushing process is dominated by plastic deformation rather than brittle fracture, thereby maximizing energy dissipation.
[0042] In one embodiment of this application, such as Figure 5 As shown, the width of the radiator grille bracket 203 on the side closest to the radiator grille body 201 is the first distance, and the width of the other side of the radiator grille bracket 203 is the second distance. The length of the first distance is greater than the length of the second distance.
[0043] Understandably, the width of the first distance is greater than that of the second distance, and the width change gradually along an S-shaped path, causing the moment of inertia of the radiator grille support 203 to change along the direction of impact force transmission. Under impact load, the structure will naturally begin buckling deformation preferentially from the narrower, relatively flexible second distance side (near the vehicle body side), and gradually extend towards the wider, more rigid first distance side (near the bumper side). This controlled, directional "progressive rear-collapse" deformation mode can more precisely manage the peak impact force, making the impact pulse transmitted to the pedestrian's lower limbs smoother. This design, combined with the symmetrical S-shaped long and short ribs 2031, significantly optimizes the dynamic response of the structure, providing a direct and effective engineering solution for reducing pedestrian lower leg injury indicators (such as tibial acceleration and flexion angle), and greatly enhancing pedestrian protection effectiveness.
[0044] In one embodiment of this application, such as Figure 5 As shown, a first space 301 is provided between two S-shaped short ribs 2031, a second space 302 is provided between two adjacent S-shaped long ribs 2032, three S-shaped long ribs 2032 in a group are formed, and a third space 303 is provided between adjacent groups of S-shaped long ribs 2032. The width of the third space 303 is greater than the width of the second space 302.
[0045] Specifically, by setting a first space 301, a second space 302, and a third space 303, the energy absorption area of the radiator grille support 203 is clearly divided. The first space 301 is located between the two central short ribs 2031 and coincides with the axis of symmetry. It usually corresponds to the initial contact and core load area in a collision. The size of this space can be independently optimized to adjust the local stiffness and deformation initiation point of the central area.
[0046] The second space 302 controls the tightness between the long ribs 2032 in a single group, directly affecting the mutual support between the ribs and the transmission of local crush waves. The larger third space 303 forms a clear interval between the groups of long ribs 2032, allowing each group to have a certain degree of independent deformation sequence during collision, and providing sufficient deformation space.
[0047] This "dense-sparse-dense" or gradient spatial layout enables intelligent distribution of structural stiffness within the plane, allowing collision loads to be transmitted and distributed more orderly according to the design path.
[0048] In one embodiment of this application, such as Figure 1 As shown, the front bumper mechanism 100 includes an upper bumper body 101, a middle bumper body 102, and a lower bumper body 103.
[0049] The upper body 101, the middle body 102, and the lower body 103 of the bumper are arranged in sequence. The mounting plate 202 of the radiator grille is connected to the upper body 101 of the bumper through a first fastener 401, which is a bolt or a buckle or a combination of both.
[0050] It should be noted that the radiator grille described in this embodiment is also connected to the bumper body by a snap-fit mechanism, which facilitates the installation and removal of the radiator grille.
[0051] Understandably, dividing the front bumper mechanism 100 into three parts—upper, middle, and lower—aligns with the modular design philosophy of modern automotive industry. This split structure not only facilitates individual manufacturing, painting, and quality control but also simplifies the assembly process on the final assembly line, improving production efficiency. The radiator grille mounting plate 202 is connected to the upper bumper body 101 via the first fastener 401 (bolt / clip), ensuring accurate positioning and easy operation of this critical safety component, which helps guarantee consistency in mass production.
[0052] In addition, the modular design of the front bumper mechanism 100 and the connection of the radiator grille mounting plate 202 to the bumper body 101 using the first fastener 401 make it convenient to replace only the three damaged front bumper bodies or the radiator grille mechanism 200 when the vehicle is involved in a low-speed collision or needs repair, without having to replace the entire large bumper assembly, which significantly reduces repair costs and time.
[0053] In one embodiment of this application, such as Figure 3 As shown, the two S-shaped short ribs 2031 are connected to each other and the two S-shaped short ribs 2031, multiple S-shaped long ribs 2032, fixing plate 2033 and two connecting plates 2034 are connected by multi-point welding.
[0054] It should be noted that the multi-point welding connection provides significantly higher stiffness and strength than snap-fit or adhesive connections. In the event of a head-on collision, the impact force is rapidly introduced through the fixing plate 2033 and then distributed almost without loss to each S-shaped long rib 2032 and short rib 2031 via the welded joints, stimulating synchronous and coordinated buckling deformation. This avoids interruption of energy absorption or structural instability due to premature failure of the connection, ensuring that all S-shaped ribs can fully participate in and complete their pre-set, long-stroke progressive crushing process, thereby maximizing the overall energy absorption capacity and efficiency of the ASA material structure.
[0055] In one embodiment of this application, such as Figure 6 As shown, there are multiple rectangular weld points between the radiator grille bracket 203 and the radiator grille mounting plate 202. The multiple rectangular weld points are symmetrically arranged, and the size of the rectangular weld points is 20.5mm×30.5mm.
[0056] Specifically, the 20.5mm × 30.5mm rectangular weld points not only provide data support for automated welding equipment but also offer a larger effective welding area and connection strength compared to traditional circular or small-sized weld points. This ensures that under severe forward collision loads, the collision energy can be efficiently and losslessly transferred from the radiator grille mounting plate 202 to the S-shaped multi-ribbed support structure below it, fully activating the latter's progressive crushing energy absorption function and preventing the entire energy absorption structure from losing its function due to connection interface failure.
[0057] The symmetrical arrangement of multiple rectangular weld points echoes the symmetrical structure of the radiator grille bracket 203 itself. This symmetrical force input method ensures that the impact load is evenly distributed to the various S-shaped ribs (short rib 2031 and long rib 2032) of the bracket, promoting smooth and coordinated deformation of the bracket as a whole, rather than twisting or premature failure on one side. This is crucial for achieving a controllable and predictable energy absorption process and is directly related to the stability of pedestrian protection performance.
[0058] In one embodiment of this application, such as Figure 3 As shown, the two ends of the S-shaped long rib 2032 pass through the fixing plate 2033 and the two connecting plates 2034, respectively.
[0059] Understandably, by designing the S-shaped long rib 2032 to penetrate both the fixed plate 2033 and the connecting plate 2034, the connection between the long rib 2032 and these connectors is no longer a simple end-to-end contact or partial welding, but rather a reinforced connection that fully encloses and fuses the entire cross-section. This significantly enhances the bending and shear strength of the connection area, ensuring that under impact loads, stress is no longer concentrated at the joint line between the end of the long rib 2032 and the plate, but is evenly distributed along the entire length of the long rib 2032. Therefore, the connection point is no longer a weak link in the structure, preventing premature fracture or unexpected bending failure at this location.
[0060] The automobile according to embodiments of the present invention includes the front bumper of the automobile in the above embodiments, thereby improving the safety of the automobile during driving.
[0061] Since the car in this embodiment includes the front bumper of the first aspect embodiment, it has all the beneficial effects of the front bumper, so it will not be described again here.
[0062] In summary, the front bumper and automobile of this application embodiment, by setting the radiator grille bracket as an S-shaped mechanism, together with the mounting plate on the radiator grille, form an integrated forward collision composite energy absorption structure, which significantly improves the collision energy absorption efficiency and buffer performance, greatly reduces the risk of pedestrians suffering serious injury during forward collisions, and provides effective pedestrian protection.
