Description

Technical Field

[0001] The present invention relates to the field of automobile anti-collision bar structures, and in particular to an automobile anti-collision structure and a vehicle. Background Art

[0002] With the development of automobile manufacturing technology, the number of cars in the country has continued to increase, and cars have become an indispensable means of transportation in people's lives. When purchasing a car, people tend to pay more attention to the safety of the car, especially the safety performance of the anti-collision structure during a collision.

[0003] In the prior art, automobile bumpers lack structural rigidity, making them prone to deformation, impacting occupant comfort, and even cracking in severe cases, seriously impacting the safety of people and property. Therefore, enhancing the structural rigidity and strength of off-road vehicle front bumpers significantly impacts vehicle safety. Summary of the Invention

[0004] The embodiments of the present invention provide an automobile anti-collision structure and a vehicle to solve the problem in the related art that the automobile anti-collision bar structure has insufficient rigidity, is easily deformed, affects the passenger feeling, and may even crack in severe cases.

[0005] In a first aspect, an automobile anti-collision structure is provided, which includes: two front anti-collision plates, the two front anti-collision plates are arranged in parallel, and at least one front anti-collision rod is fixed between the two front anti-collision plates; two anti-collision assemblies, the two anti-collision assemblies correspond one-to-one to the two front anti-collision plates, and the two anti-collision assemblies are fixed on the corresponding front anti-collision plates; and a reinforced anti-collision beam, the reinforced anti-collision beam is fixed between the two anti-collision assemblies.

[0006] The technical effect of adopting the above scheme is that, in the event of a low-speed collision, the front anti-collision plate and the front anti-collision bar can initially crush and absorb energy; when the collision intensity is too large, the remaining energy will continue to be transmitted to the anti-collision assembly, and crush and absorb energy again, thereby improving the reliability of the car's anti-collision structure. At the same time, the anti-collision beam is strengthened to strengthen the car's anti-collision structure, prevent deformation of the rear structure, protect the cabin components, and improve maintenance economy; finally, the remaining energy is transmitted to the front longitudinal beam assembly of the entire vehicle, causing it to deform slightly, thereby protecting the safety of the cabin and occupants.

[0007] In some embodiments, each of the front bumper plates includes a vertical section and a curved section connected to each other, so that the front bumper plate is roughly L-shaped; one end of the bumper assembly is fixed to the corresponding vertical section of the front bumper plate, and the other end thereof is used to be fixed to the front longitudinal beam assembly of the entire vehicle; each curved section of the front bumper plate is used to be fixed to the front cross beam assembly of the entire vehicle.

[0008] The technical effect of adopting the above solution is that when the anti-collision structure encounters a collision, its energy is first absorbed by the front anti-collision plate and the front anti-collision bar, and then transferred to the anti-collision assembly at its vertical section, which further collapses and absorbs energy. The remaining energy is then transferred to the front longitudinal beam assembly of the entire vehicle for absorption. At the same time, the remaining energy is dispersed and transferred to the curved section of the front anti-collision plate, and finally to the front cross beam assembly of the entire vehicle. This can reduce the total impact force borne by the front longitudinal beam assembly, allowing the curved section of the front anti-collision plate to effectively disperse the impact energy received from the front, dispersing the impact force to the front cross beam assembly, ensuring the life safety of the driver in the vehicle. This greatly improves the force transmission path during a collision and effectively disperses the energy during the collision to the front cross beam assembly.

[0009] In some embodiments, each of the anti-collision assemblies includes: two connecting longitudinal beams, which are spaced apart in the height direction of the vehicle body, and one end of each of the connecting longitudinal beams is fixed to the corresponding front anti-collision plate.

[0010] The technical benefit of this solution is that the connecting longitudinal beam adopts a two-layer structure, preventing the anti-collision structure from reversing and failing during a collision. The center height of the connecting longitudinal beam is basically the same as the center height of the front crossbeam assembly, reducing torque and facilitating force transmission.

[0011] In some embodiments, each of the anti-collision assemblies includes: a connecting oblique beam, which is fixed between one of the connecting longitudinal beams and the corresponding front anti-collision plate.

[0012] The technical effect of adopting the above scheme is that the connecting oblique beam enables the connecting longitudinal beam to be connected and fixed to the upper part of the front bumper plate, so that when the upper part of the front bumper plate encounters a collision, its impact force will be dispersed and transmitted to the connecting longitudinal beam through the connecting oblique beam for crushing and energy absorption, thus solving the problem of weak anti-collision ability of the upper part of the existing anti-collision structure.

[0013] In some embodiments, the automobile anti-collision structure includes: two anti-collision assemblies 2, and the two anti-collision assemblies 2 correspond one-to-one to the two anti-collision assemblies; each anti-collision assembly 2 is arranged in a conical shape, and the narrow end of each anti-collision assembly 2 is used to be fixed to the front bumper of the entire vehicle, and the wide end is fixed to the corresponding anti-collision assembly 1.

[0014] The technical effect of adopting the above scheme is that, when facing a side collision, the anti-collision assembly 2 can transfer the impact force to one part of the anti-collision assembly for dispersion, thereby playing a side protection role; the cone-shaped structure formed between the anti-collision assembly 2 and the anti-collision assembly 1 can enhance the ability of the structure to defend against oblique collisions.

[0015] In some embodiments, each of the anti-collision assemblies 2 includes: a side anti-collision bar 1, one end of which is fixed to the corresponding anti-collision assembly 1, and the other end of which is used to be fixed to the front bumper of the entire vehicle; the side anti-collision bar 1 is bent and extended toward the outside of the vehicle body and toward the upper rear of the vehicle body.

[0016] The technical effect of adopting the above solution is that when the side anti-collision bar faces a side collision, its impact force is transmitted to the anti-collision assembly for dispersion, thereby playing a side protection role.

[0017] In some embodiments, each of the anti-collision assemblies 2 includes: a side anti-collision bar 2, one end of which is fixed to the corresponding anti-collision assembly 1, and the other end of which is fixed to the side anti-collision bar 1; the curved path of the side anti-collision bar 2 is roughly the same as the curved path of the side anti-collision bar 1.

[0018] The technical effect of adopting the above scheme is that, when the side impact bar 2 faces a collision, it can improve the dispersion of its side impact force, so that part of the energy is dispersed to one part of the impact bar assembly. The side impact bar 2 and the side impact bar 1 are roughly located on the same plane, which can increase the collision area of the front.

[0019] In some embodiments, each of the anti-collision assemblies 2 includes: a side anti-collision bar 3, one end of which is fixed to the corresponding anti-collision assembly 1, and the other end of which is fixed to the side anti-collision bar 1; the side anti-collision bar 3 and the side anti-collision bar 1 are arranged crosswise.

[0020] The technical effect of adopting the above solution is that the side impact bar three can further improve the collision strength of the side impact bar two and the side impact bar one, provide good supporting strength, and have good strength and stability.

[0021] In some embodiments, at least one anti-collision reinforcement bar is fixed inside each of the front anti-collision plates.

[0022] The technical effect of adopting the above solution is that when the front bumper plate faces a head-on collision, the bumper reinforcement bar ensures a certain structural strength while also being able to perform good crush energy absorption.

[0023] In a second aspect, a vehicle is provided, comprising the above-mentioned automobile anti-collision structure.

[0024] The technical effect of adopting the above scheme is that the impact force generated by the collision of the car is absorbed by the collapse of the car anti-collision structure, thereby reducing the deformation of the car body and further protecting the occupants of the car. At the same time, it is easy to disassemble and maintain; the structure is welded, the structure is simple, and the maintainability is good.

[0025] The beneficial effects brought about by the technical solution provided by the present invention include: in the event of a low-speed collision, the front anti-collision plate and the front anti-collision bar can initially crush and absorb energy; when the collision intensity is too large, the remaining energy will continue to be transmitted to the anti-collision assembly to crush and absorb energy again, thereby improving the reliability of the car's anti-collision structure. At the same time, the anti-collision beam is strengthened to strengthen the car's anti-collision structure, prevent the rear structure from deforming, protect the cabin components, and improve maintenance economy; finally, the remaining energy is transmitted to the front longitudinal beam assembly of the entire vehicle, causing it to deform slightly, thereby protecting the safety of the cabin and occupants.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] The embodiments of the present invention provide an automobile anti-collision structure and a vehicle to solve the problem in the related art that the automobile anti-collision bar structure has insufficient rigidity, is easily deformed, affects the passenger feeling, and may even crack in severe cases.

[0035] like Figure 1 As shown, an embodiment of the present invention provides an automobile anti-collision structure, which includes: two front anti-collision plates 1, the two front anti-collision plates 1 are arranged in parallel, and at least one front anti-collision bar 2 is fixed between the two front anti-collision plates 1; two anti-collision assemblies 3, the two anti-collision assemblies 3 correspond to the two front anti-collision plates 1 one by one, and the two anti-collision assemblies 3 are fixed on the corresponding front anti-collision plates 1; and a reinforced anti-collision beam 4, the reinforced anti-collision beam 4 is fixed between the two anti-collision assemblies 3. Figure 3 and 4 As shown, the front anti-collision plate 1 is fixedly mounted on the front longitudinal beam assembly 6 of the vehicle through the corresponding anti-collision assembly 3.

[0036] Specifically, such as Figure 1 As shown, in a low-speed collision, the front anti-collision plate 1 and the front anti-collision bar 2 can first be initially crushed to absorb energy; when the collision intensity is too large, the remaining energy will continue to be transmitted to the anti-collision assembly 3, and crush and absorb energy again, thereby improving the reliability of the vehicle's anti-collision structure. At the same time, the anti-collision beam 4 is strengthened to strengthen the vehicle's anti-collision structure, prevent deformation of the rear structure of the entire vehicle, protect the cabin components, and improve maintenance economy; finally, the remaining energy is transmitted to the front longitudinal beam assembly 6 of the entire vehicle, causing it to deform slightly, thereby protecting the cabin and occupants.

[0037] In some optional embodiments, such as Figure 1 As shown, the front bumper bar 2 can be provided in multiple pieces and arranged in parallel in the vehicle body height direction, which can further improve the structural strength of the front bumper plate 1 and the front bumper bar 2 and improve their collision performance. Specifically, both ends of the front bumper bar 2 are installed through the interior of the two front bumper plates 1, which can also further improve the structural performance of the front bumper bar 2.

[0038] Of course, the bottom front anti-collision bar 2 can be roughly located at the same horizontal plane as the reinforced anti-collision beam 4 behind it, so that the front anti-collision bar 2 below it can first withstand the impact force and play a protective role for the reinforced anti-collision beam 4 behind it. In this way, when facing a low-speed and minor collision, the integrity of the reinforced anti-collision beam 4 is guaranteed, its maintenance cost is reduced, and the economy of the automobile anti-collision structure is improved.

[0039] In some optional embodiments, both ends of the front anti-collision bar 2 may also be fixed between the two front anti-collision plates 1 , which can also provide a good frontal anti-collision effect.

[0040] In some optional embodiments, such as Figure 2 As shown, the front bumper plate 1 may include a hollow bumper plate body and two encapsulation ribs. The two encapsulation auxiliary plates are used to encapsulate and be fixed on opposite sides of the hollow bumper plate body, which can improve the crushing energy absorption effect of the front bumper plate 1 and also make the bumper structure lightweight.

[0041] In some embodiments, such as Figure 2 、 3 As shown in Figures 4 and 5, each front bumper plate 1 includes a vertical section and a curved section connected to each other, forming a generally L-shaped front bumper plate 1. One end of the bumper assembly 3 is fixed to the corresponding vertical section of the front bumper plate 1, and the other end is used to be fixed to the front longitudinal beam assembly 6 of the vehicle. The curved section of each front bumper plate 1 is used to be fixed to the front cross beam assembly 7 of the vehicle. When the bumper structure encounters an impact, the energy is first absorbed by the front bumper plate 1 and the front bumper bar 2, and then transferred to the bumper assembly 3 at its vertical section, where it further collapses and absorbs energy. The remaining energy is then transferred to the front longitudinal beam assembly 6 of the vehicle for absorption. At the same time, the remaining energy is dispersed and transferred to the curved section of the front bumper plate 1, and finally to the front cross beam assembly 7 of the vehicle. This can reduce the total impact force borne by the front longitudinal beam assembly 6, allowing the curved section of the front bumper plate 1 to effectively disperse the impact energy received from the front, distributing the impact force to the front cross beam assembly 7, thereby ensuring the safety of the driver in the vehicle. The force transmission path during the collision is greatly improved, and the energy during the collision is effectively dispersed and transmitted to the front crossbeam assembly 7.

[0042] Specifically, the curved section of the front bumper plate is passed through the front crossbeam assembly 7 and fixed to the lower end surface of the front longitudinal beam assembly 6 by two bolts and a mounting sleeve, thereby increasing the force transmission path and effectively dispersing the energy during the collision to the front crossbeam assembly 7.

[0043] In some embodiments, such as Figure 2As shown, each anti-collision assembly 3 may include two connecting longitudinal beams 31, spaced apart in the vehicle body height direction, with one end of each connecting longitudinal beam 31 secured to the corresponding front anti-collision plate 1. The connecting longitudinal beams 31 are hollow, capable of collapsing and absorbing energy in the event of an impact. The connecting longitudinal beams 31 employ a two-layer structure to prevent reverse failure of the anti-collision structure during a collision. The center height of the connecting longitudinal beams 31 is substantially the same as that of the front crossbeam assembly 7, reducing torque and facilitating force transmission.

[0044] Specifically, both ends of the reinforced anti-collision beam 4 are fixed to the sides of the four connecting longitudinal beams 31 to ensure the connection strength of the reinforced anti-collision beam 4. The two ends of the reinforced anti-collision beam 4 can also be fixed to a single connecting longitudinal beam 31. The reinforced anti-collision beam 4 strengthens the anti-collision structure of the vehicle, prevents deformation of the rear structure, protects the cabin components, and improves maintenance efficiency.

[0045] More specifically, Figure 3 As shown, the end faces of the front longitudinal beam assembly 6 and the connecting longitudinal beam 31 that are close to each other are both installed with anti-collision mounting plates, and the front longitudinal beam assembly 6 and the connecting longitudinal beam 31 are fixedly installed by bolts through the anti-collision mounting plates thereon.

[0046] In some optional embodiments, the number of connecting longitudinal beams 31 on the same side can also be set to three or four, and the reinforcing anti-collision beams 4 therebetween can be correspondingly thickened to further improve the structural strength of the automobile anti-collision structure.

[0047] In some optional embodiments, the number of connecting longitudinal beams 31 on the same side can also be set to three to four, and the two connecting longitudinal beams 31 on the opposite sides and located on the same horizontal plane are fixed with a reinforced anti-collision beam 4, thereby increasing the impact energy of the reinforced anti-collision beam 4 facing a large range of frontal impacts, further improving the safety of the automobile anti-collision structure.

[0048] In some optional embodiments, two connecting longitudinal beams 31 on opposite sides and located at the same horizontal plane are a group, and the reinforced anti-collision beams 4 can be arranged to be installed and fixed at intervals of one group, which can also improve the structural performance of the anti-collision assembly 3, while also ensuring that the cost of the automobile anti-collision structure can be reduced.

[0049] In some embodiments, such as Figure 2 and 3As shown, each of the anti-collision assemblies 3 may include a connecting oblique beam 32, which is fixed between one of the connecting longitudinal beams 31 and the corresponding front anti-collision plate 1. The connecting oblique beam 32 enables the connecting longitudinal beam 31 to be connected and fixed to the upper portion of the front anti-collision plate 1. Therefore, when the upper portion of the front anti-collision plate 1 encounters a collision, the impact force is dispersed and transmitted through the connecting oblique beam 32 to the connecting longitudinal beam 31 for energy absorption. This solves the problem of weak anti-collision capability of the upper portion of the existing anti-collision structure and prevents severe deformation of the vehicle's anti-collision mechanism due to an excessively long upper lever arm of the front anti-collision plate 1.

[0050] In some optional embodiments, one end of the connecting oblique beam 32 can be fixed on the corresponding front bumper plate 1, and the other end can be fixed on the upper end surface of the front longitudinal beam assembly 6 of the entire vehicle, so that the energy transmitted from the connecting oblique beam 32 is transmitted to the front longitudinal beam assembly 6 for crushing energy absorption.

[0051] In some optional embodiments, two connecting diagonal beams 32 can be provided, one fixed on the front bumper plate 1 and the connecting longitudinal beam 31, and the other fixed between the front bumper plate 1 and the front longitudinal beam assembly 6 of the entire vehicle, thereby realizing an additional force transmission path, greatly improving the anti-collision performance of the automobile anti-collision structure, and realizing the dispersed transmission of concentrated frontal impact energy, ensuring the safety of passengers on the vehicle, and minimizing the risk of injury to passengers.

[0052] In some embodiments, such as Figure 1 and 2 As shown, the vehicle crash prevention structure may include: two crash prevention assemblies 2 5, each corresponding one-to-one to the two crash prevention assemblies 1 3; each crash prevention assembly 2 5 is tapered, with its narrow end secured to the front bumper 8 of the vehicle and its wide end secured to the corresponding crash prevention assembly 1 3. In the event of a side collision, the crash prevention assembly 2 5 can transmit the impact force to the crash prevention assembly 1 3 for dispersion, providing side protection. This also disperses the impact force to the crash prevention assembly 1 3, further enhancing the force dispersion effect of the vehicle crash prevention structure.

[0053] Specifically, a conical structure is formed between the anti-collision assembly 2 5 and the connecting longitudinal beam 31 and the connecting oblique beam 32, which can enhance the ability of the structure to defend against oblique collisions.

[0054] In some embodiments, each of the anti-collision assemblies 2 5 may include: a side anti-collision bar 1 51, one end of which is fixed to the corresponding anti-collision assembly 3, and the other end of which is used to be fixed to the front bumper 8 of the entire vehicle; the side anti-collision bar 1 51 is bent and extended toward the outside of the vehicle body and toward the upper rear of the vehicle body. Specifically, Figure 2and 5 As shown, one end of the side impact bar 1 51 is fixed to the uppermost connecting longitudinal beam 31, and the other end is fixed to the side impact bar mounting plate on the front bumper 8 via the side impact bar mounting plate. When a side collision occurs, the side impact bar 1 51 transfers the impact force to the uppermost connecting longitudinal beam 31 for dispersion, thereby providing side protection.

[0055] In some embodiments, each of the two anti-collision assemblies 5 may include a second side impact bar 52, one end of which is fixed to the corresponding one of the anti-collision assemblies 3 and the other end of which is fixed to the one of the side impact bar 51; the curvature of the second side impact bar 52 is substantially the same as the curvature of the one of the side impact bar 51. Specifically, one end of the second side impact bar 52 is welded to the one of the side impact bar 51 and the other end is welded to the connecting diagonal beam 32. Based on the side impact bar 51, the second side impact bar 52 disperses some of the energy during a collision to the connecting diagonal beam 32, which is then transferred to the front anti-collision plate 1. In the event of a side impact, the energy can be dispersed to the anti-collision assembly 3 and the front anti-collision plate 1, greatly improving the dispersion of the side impact force.

[0056] At the same time, the second side impact bar 52 and the first side impact bar 51 are substantially located on the same plane, which can increase the collision area of the side surface.

[0057] In some embodiments, such as Figure 2 As shown, each of the second anti-collision assemblies 5 can include a third side impact bar 53, one end of which is fixed to the corresponding first anti-collision assembly 3 and the other end of which is fixed to the first side impact bar 51; the third side impact bar 53 and the first side impact bar 51 are arranged in a cross-arrangement. Specifically, one end of the third side impact bar 53 is fixed to the first side impact bar 51, and the other end is fixed to the topmost connecting longitudinal beam 31, and can also be fixed to the bottommost connecting longitudinal beam 31. The third side impact bar 53 can further improve the impact resistance of the second side impact bar 52 and the first side impact bar 51, providing good support strength.

[0058] Finally, the three circular tubes of the second anti-collision assembly 5 form a conical structure with good strength and stability, which can effectively transmit the impact force generated by the side collision to the two connecting longitudinal beams 31 and the connecting oblique beam 32 through the side anti-collision bar 1 51, the side anti-collision bar 2 52 and the side anti-collision bar 3 53, thereby playing a side protection role.

[0059] In some embodiments, such as Figure 2As shown, at least one anti-collision reinforcement bar 11 is fixed inside each of the front bumper plates 1. The anti-collision reinforcement bar 11 is positioned approximately in the same plane as the upper end of the connecting diagonal beam 32. When the front bumper plate 1 faces a head-on collision, the anti-collision reinforcement bar 11 ensures a certain level of structural strength while also providing excellent crush energy absorption. Specifically, when the anti-collision reinforcement bar 11 is subjected to a large amount of impact force, it is transmitted to the connecting diagonal beam 32 behind it, where it is then dispersed and transmitted to the connecting longitudinal beam 31 through the connecting diagonal beam 32. This allows the impact force to be crushed and absorbed by the bumper assembly 3, thereby increasing the force transmission path and enhancing the crash resistance of the vehicle's anti-collision structure.

[0060] In summary, the sheet metal parts in the anti-collision structure of the automobile in some of the above embodiments are made of ultra-high strength materials, and can be mainly connected by two overlapping methods: welding and bolt connection.

[0061] In some embodiments, a vehicle can be installed with the above-mentioned automobile anti-collision structure. In the event of a low-speed collision, the front anti-collision plate 1 and the front anti-collision bar 2 can initially collapse and absorb energy; when the collision intensity is too large, the remaining energy will continue to be transferred to the anti-collision assembly 1 3, and will be crushed and absorbed again, thereby improving the reliability of the automobile anti-collision structure. At the same time, the anti-collision beam 4 is strengthened to strengthen the automobile anti-collision structure, prevent the rear structure from deforming, protect the cabin components, and improve the maintenance economy; finally, the remaining energy is transferred to the front longitudinal beam assembly 6 of the entire vehicle, and its impact energy is dispersed and transferred to the front cross beam assembly 7, causing it to deform slightly, thereby protecting the cabin and the occupants. The anti-collision structure collapses and absorbs the impact force generated when the car collides, thereby reducing the deformation of the car body and further protecting the occupants on the car. It is easy to disassemble and maintain; the structure is welded, simple in structure, and has good maintainability.
