Detailed Implementation

[0032] The core of this invention is to provide a front bumper assembly for automobiles to improve driving safety. Another core aspect of this invention is to provide an automobile that includes the aforementioned front bumper assembly.

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] To facilitate understanding, some terms are explained below.

[0035] Anti-collision beams: Structures used to absorb collision energy when a vehicle is involved in a collision.

[0036] Energy-absorbing box: An important energy-absorbing device. In the event of a collision, the energy-absorbing box can collapse and absorb energy, thereby protecting the safety of the occupants.

[0037] Crusher guides: A design used in collision structures, primarily found in energy-absorbing boxes and other collision mitigation components. Their main function is to use the physical shape of the component to cause the energy-absorbing box to deform as intended, thereby protecting the main vehicle body structure. Upon impact, the crumple guide guides allow the energy-absorbing box to absorb collision energy and deform in a predetermined direction, thus transferring the collision energy rearward and reducing damage to the main body of the vehicle.

[0038] Please refer to Figures 1 to 8 .

[0039] In one specific implementation, such as Figure 1 As shown in the figure, the front anti-collision assembly 32 of the automobile provided in this specific embodiment of the present invention includes an upper anti-collision component 1 and a lower anti-collision component 2. The upper anti-collision component 1 includes a front upper anti-collision beam 3, a left upper energy-absorbing box 10, and a right upper energy-absorbing box 6. The left upper energy-absorbing box 10 and the right upper energy-absorbing box 6 are both installed on the back of the front upper anti-collision beam 3, and the back side of the front upper anti-collision beam 3 forms an installation cavity for accommodating the cooling module 33. Specifically, the upper anti-collision component 1 serves as the main anti-collision beam, the lower anti-collision beam assembly serves as the secondary beam, and the left upper energy-absorbing box 10 and the right upper energy-absorbing box 6 can be welded together. During assembly, the left upper energy-absorbing box 10 and the right upper energy-absorbing box 6 are welded to the upper anti-collision beam, or the left upper energy-absorbing box 10 and the right upper energy-absorbing box 6 are detachably connected to the upper anti-collision beam.

[0040] The lower bumper assembly 2 includes a front lower bumper beam 15, a left lower energy-absorbing box 17, and a right lower energy-absorbing box 21. The front lower bumper beam 15 is located below the front upper bumper beam 3. The left lower energy-absorbing box 17 and the right lower energy-absorbing box 21 are both installed on the back of the front lower bumper beam 15, with the back of the front lower bumper beam 15 facing away from the direction of vehicle travel. The left lower energy-absorbing box 17 and the right lower energy-absorbing box 21 can be welded together, and can be welded to the front lower bumper beam 15 or detachably connected.

[0041] The bottom end of the upper left energy-absorbing box 10 is connected to the lower left energy-absorbing box 17, and the bottom end of the upper right energy-absorbing box 6 is connected to the lower right energy-absorbing box 21. Specifically, the bottom end of the upper left energy-absorbing box 10 is welded to or detachably connected to the lower left energy-absorbing box 17. The bottom end of the upper right energy-absorbing box 6 is welded to or detachably connected to the lower right energy-absorbing box 21.

[0042] like Figure 5 As shown, in the specific design, the lengths of the upper left energy-absorbing box 10 and the upper right energy-absorbing box 6 are 100mm-160mm, specifically 130mm; the lengths of the lower left energy-absorbing box 17 and the lower right energy-absorbing box 21 are 400mm-460mm, specifically 430mm. Of course, in the specific design, energy-absorbing boxes of sufficient length can better absorb and disperse the energy generated by the collision. By absorbing the energy of the collision through the plastic deformation of the energy-absorbing box, the body structure can be better protected, the integrity of the passenger compartment can be maintained, and the safety of the occupants can be ensured.

[0043] Both the upper anti-collision component 1 and the lower anti-collision component 2 can be steel structures. Preferably, the upper anti-collision component 1 is made of aluminum alloy. For example, the front upper anti-collision beam 3 uses lightweight materials such as aluminum alloy sheet metal, requiring relatively less mold investment. The front upper anti-collision beam 3 takes into account the characteristics of aluminum alloy material. Aluminum alloy material has low density, is lightweight and strong, and has high tensile strength, while its low density strikes a balance between cost and performance. In the event of a traffic accident, the strength of aluminum alloy sheet metal can better absorb the energy generated by the collision, protecting the safety of occupants, reducing overall vehicle damage, and lowering vehicle repair costs.

[0044] The front lower bumper beam 15, also known as the pedestrian leg bumper beam, can change the direction of the human body in the protection structure for the pedestrian's legs. The front lower bumper beam 15 increases the contact area of ​​the front bumper assembly 32, so that the human body is guided in the correct direction, thereby preventing pedestrians from being rolled under the vehicle. In the event of a violent collision, it can better protect the safety of the occupants.

[0045] The front lower bumper beam 15 can be made of steel sheet metal structure, which has high dimensional accuracy, low unit cost, and is suitable for mass production.

[0046] To improve connection strength, the components within the upper anti-collision assembly 1 and the lower anti-collision assembly 2 are preferably welded parts, that is, the components are fixed internally by welding.

[0047] As described above, the front bumper assembly 32 for automobiles provided in this specific embodiment includes an upper front bumper beam 3 and a lower front bumper beam 15. These, combined with the upper left energy-absorbing box 10, upper right energy-absorbing box 6, lower left energy-absorbing box 17, and lower right energy-absorbing box 21, effectively protect the vehicle body. The lower front bumper beam 15 is located below the upper front bumper beam 3, further reducing the risk of objects being pulled under the vehicle. The back side of the upper front bumper beam 3 forms a mounting cavity for the cooling module 33, thus protecting the cooling module 33. Therefore, the front bumper assembly 32 for automobiles provided in this application improves vehicle safety.

[0048] like Figure 4 As shown, in one specific embodiment, along the longitudinal direction of the vehicle, the upper left energy-absorbing box 10, the upper right energy-absorbing box 6, the lower left energy-absorbing box 17, and the lower right energy-absorbing box 21 are provided with multiple crumple guide grooves 36. Specifically, each rounded corner of the upper left energy-absorbing box 10 and the upper right energy-absorbing box 6 is designed with two crumple guide grooves 36. The crumple guide grooves 36 are located at... Figure 4 The position indicated by the rectangle in the middle.

[0049] The crumple guide grooves 36 on the lower left energy-absorbing box 17 and the lower right energy-absorbing box 21 are strip-shaped guide grooves. These strip-shaped guide grooves are located on opposite sides of the lower left energy-absorbing box 17 and the lower right energy-absorbing box 21, and on opposite sides facing away from each other. The top of the strip-shaped guide grooves extends to the top of the lower left energy-absorbing box 17 and the lower right energy-absorbing box 21, and the bottom of the strip-shaped guide grooves extends to the bottom of the lower left energy-absorbing box 17 and the lower right energy-absorbing box 21. In other words, the crumple guide grooves 36 on the lower left energy-absorbing box 17 and the lower right energy-absorbing box 21 are located on the sides, allowing the front bumper assembly to deform in a predetermined direction during a collision. This also strengthens the protective performance of the bumper beam. The front bumper beam can guide the vehicle body forward or sideways through deformation, preventing excessive tilting or rollover and maintaining vehicle stability.

[0050] Of course, the rear side of the front lower bumper beam 15 is provided with multiple crumple zone guide grooves 36. Specifically, the crumple zone guide grooves 36 provided on the rear side of the front lower bumper beam 15 are arranged sequentially from left to right along the vehicle.

[0051] In one specific embodiment, the cross-sectional area of ​​the collapse guide groove 36 gradually decreases along the direction perpendicular to the opening to the bottom of the groove. The collapse guide groove 36 can be a V-shaped groove with a gradually increasing opening, so that the collapse guide groove 36 gradually deforms when subjected to external compressive force.

[0052] According to the collision force transmission path, a crumple guide groove 36 is set so that the vehicle can deform in a predetermined direction during the collision process, thus ensuring the stability of the vehicle.

[0053] like Figure 1 As shown, in one specific embodiment, the lower anti-collision assembly 2 further includes a curved beam mounting member 19. One end of the curved beam mounting member 19 is connected to the lower left energy-absorbing box 17, and the other end is connected to the lower right energy-absorbing box 21. Specifically, the left end of the curved beam mounting member 19 is connected to the lower left energy-absorbing box 17 via a left curved beam connector 18, and the right end of the curved beam mounting member 19 is connected to the lower right energy-absorbing box 21 via a right curved beam connector 20. The ends of the lower left energy-absorbing box 17 and the lower right energy-absorbing box 21 furthest from the lower anti-collision beam 15 are fixedly connected to the front subframe 35. By providing the curved beam mounting member 19, the overall strength of the lower anti-collision assembly 2 is improved. Specifically, in the front anti-collision assembly 32, except for the curved beam mounting member 19, the left curved beam connector 18, and the right curved beam connector 20, which are welded together by spot welding, the remaining parts are welded together by CO2 shielded welding.

[0054] In one specific embodiment, the upper anti-collision component 1 is fixedly connected to the vehicle body longitudinal beam. Specifically, the front upper anti-collision beam 3 is connected to the front subframe 35. The use of the front upper anti-collision beam 3 and the front lower anti-collision beam 15, with the front upper anti-collision beam 3 connected to the vehicle body longitudinal beam and the front lower anti-collision beam 15 connected to the front subframe 35, forms a closed-loop structure. This effectively enhances the vehicle's ability to cope with collisions, demonstrating significant advantages in protecting the vehicle's structural integrity and improving vehicle rigidity, making it particularly important in the fiercely competitive new energy vehicle market.

[0055] In one specific embodiment, the lower front bumper beam 15 is located in front of the upper front bumper beam 3 along the direction of vehicle travel. The lower front bumper beam 15 guides the pedestrian being hit, distributing them in a staggered manner, thereby reducing the impact force on multiple parts of the pedestrian at the same time.

[0056] In one specific embodiment, the front lower bumper beam 15 is a V-shaped bent plate with its front end protruding towards the front of the vehicle.

[0057] like Figure 3 As shown, in one specific embodiment, the upper anti-collision assembly 1 has an upper mounting position 30 for installing the cooling module 33, and the lower anti-collision assembly 2 has a lower mounting position 31 for installing the cooling module 33. The cooling module 33 is a front-end cooling module for the vehicle, and the cooling module 33 is connected to the upper mounting position 30 and the lower mounting position 31. This application makes full use of the front space of the vehicle, and the cooling module 33 is located inside the main beam and the front anti-collision assembly 32. The main beam is specifically the longitudinal beam of the vehicle body. When the vehicle is impacted, it can ensure that the cooling module 33 is not damaged to a certain extent.

[0058] In one specific embodiment, both ends of the upper front bumper beam 3 are connected to the lower front bumper beam 15 via connectors, with the upper left energy-absorbing box 10 and the upper right energy-absorbing box 6 located between the two connectors. Specifically, the left end of the upper front bumper beam 3 is connected to the left end of the lower front bumper beam 15 via the lower front bumper left connecting plate 14, or the lower front bumper left connecting plate 14 is connected to the left end of the upper front bumper beam 3 via the upper front bumper beam left connecting plate 13. The right end of the upper front bumper beam 3 is connected to the right end of the lower front bumper beam 15 via the lower front bumper right connecting plate 24, or the lower front bumper right connecting plate 24 is connected to the right end of the upper front bumper beam 3 via the upper front bumper beam right connecting plate 9.

[0059] The upper front bumper beam 3 has an upper curved beam mounting bracket 5 at its top and a radar mounting bracket 4 at its bottom. The radar mounting bracket 4 is located above the lower front bumper beam 15. Headlight mounting brackets are located at both ends of the upper front bumper beam 3. The headlight mounting brackets include a right front headlight mounting bracket 8 and a left front headlight mounting bracket 12. The right front headlight mounting bracket 8 is used to mount the right front headlight, and the left front headlight mounting bracket 12 is used to mount the left front headlight.

[0060] During assembly, the upper left energy-absorbing box 10 has an upper left mounting plate 11 for the front bumper beam on its back. The upper left mounting plate 11 connects to the lower left mounting plate 16, which in turn connects to the lower left energy-absorbing box 17. The upper right energy-absorbing box 6 has an upper right mounting plate 7 for the front bumper beam on its back. The upper right mounting plate 7 connects to the lower right mounting plate 23, which in turn connects to the lower right energy-absorbing box 21. To improve connection stability, a lower left mounting plate reinforcement plate 25 is provided at the connection point between the lower left mounting plate 16 and the lower left energy-absorbing box 17, and a lower right mounting plate reinforcement plate 26 is provided at the connection point between the lower right mounting plate 23 and the lower right energy-absorbing box 21. Both the lower left and lower right mounting plate reinforcement plates 25 and 26 can be L-shaped reinforcement plates.

[0061] All parts within the upper anti-collision assembly 1 provided in this application can be welded together using CO2 shielded welding.

[0062] The lower anti-collision component 2 also includes a water pump mounting bracket 22 disposed on the lower right energy absorption box 21.

[0063] like Figure 2 As shown, during assembly, the front bumper assembly 32 is horizontally mounted, with its left end fixed to the left longitudinal beam of the vehicle and its right end fixed to the right longitudinal beam. For ease of assembly and disassembly, the upper bumper assembly 1 and the lower bumper assembly 2 are preferably detachably connected. Specifically, the left connecting plate 13 and the left connecting plate 14 of the upper front bumper beam are connected by threaded fasteners 27, and the right connecting plate 9 and the right connecting plate 24 of the upper front bumper beam are connected by threaded fasteners. After assembling into the front bumper beam assembly, the upper bumper assembly 1 is connected to the front main beam 34 assembly by threaded fasteners 28, and the lower bumper assembly 2 is connected to the front subframe 35 by threaded fasteners 29, which are symmetrical about the center of the lower bumper assembly 2. This effectively absorbs the impact force of a frontal collision, reduces repair costs in low-to-medium speed collisions, and mitigates injury to occupants to some extent.

[0064] When a vehicle is involved in a collision, the impact force F is first transmitted to the front bumper assembly 32. The front bumper assembly 32 absorbs most of the collision energy through the upper left energy-absorbing box 10, the upper right energy-absorbing box 6, the lower left energy-absorbing box 17, and the lower right energy-absorbing box 21, preventing severe damage to the front structure such as the longitudinal beams and subframe. In other words, the curvature of the upper front bumper beam 3 and the lower front bumper beam 15 will deform due to the impact force, thereby offsetting most of the impact force, especially in low-speed collisions, reducing the impact force on the vehicle body, reducing the degree of damage, reducing repair costs, and also achieving the purpose of protecting the safety of the occupants. Secondly, the front bumper assembly 32 can disperse the impact force, distributing the impact force to other parts of the vehicle body, thereby effectively protecting the safety of the occupants. That is, it better realizes the transmission and weakening of the collision force, thereby reducing the deformation of the vehicle's passenger area, reducing the possible injury to the occupants, and also effectively protecting the stability of the collision structure. Meanwhile, the front collision protection assembly 32 provided in this application achieves multi-level energy absorption, which can provide different energy absorption effects in collisions at different speeds, provide better safety protection in high-speed collisions, and reduce vehicle damage and maintenance costs in low-speed collisions.

[0065] In this application, the upper anti-collision component 1 and the lower anti-collision component 2 are connected by bolts to form an integral structure, creating a closed-loop structure. This integral structure improves strength and effectively enhances the vehicle's ability to cope with collisions. The invention also features a front lower anti-collision beam 15 structure, which can change the direction of pedestrian movement. Strengthening the bottom support increases the contact area of ​​the front bumper, guiding pedestrians in the correct direction and preventing them from being trapped under the vehicle.

[0066] This application provides a vehicle including a frame and a front bumper assembly mounted at the front of the frame, wherein the front bumper assembly is any of the aforementioned front bumper assemblies 32. The specific structure of the front bumper assembly 32 has been described above; this application includes the aforementioned front bumper assembly 32 and also possesses the aforementioned technical effects.
