Description

Technical Field

[0001] The utility model belongs to the technical field of automobile body parts, and more specifically relates to a front anti-collision beam assembly and a vehicle. Background Art

[0002] With the rapid development of the automotive industry, vehicle performance and speed have increased significantly, leading to a corresponding increase in the frequency of car accidents and the resulting increase in casualties. This is because, during a traffic accident, there isn't enough space within the vehicle body to deform and absorb the energy generated by the collision, causing significant harm to the occupants. To improve vehicle safety during collisions, a safe and effective protective device is needed.

[0003] Automotive anti-collision beams are important safety devices for preventing collisions. They absorb some of the energy and distribute the impact force to other parts of the vehicle body, thereby minimizing occupant injuries. While traditional anti-collision beams can provide some impact protection, their energy absorption capacity is limited. This means that the safety of passengers in the event of a collision is still not guaranteed.

[0004] Especially in non-frontal collisions, such as when the left or right front end of the vehicle is struck, the energy absorption box cannot effectively absorb the collision energy, causing the force-bearing end of the anti-collision beam to deform or shift backward, thus threatening the safety of the driver or passengers. Therefore, how to ensure the resistance of the front anti-collision beam assembly in side collisions is a key indicator for improving vehicle safety performance. Utility Model Content

[0005] The purpose of the present utility model is to provide a front anti-collision beam assembly and a vehicle, aiming to solve the problem in the prior art that the anti-collision beam body is easily deformed or displaced backward after being hit by an external force on the left or right side, thereby affecting the safety of people in the vehicle.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] In a first aspect, a front anti-collision beam assembly is provided, comprising:

[0008] An anti-collision beam body, comprising a main anti-collision area and side anti-collision areas located at both ends of the main anti-collision area in the left and right directions, wherein the side anti-collision areas include a transition portion and an extension portion connected in sequence, wherein the transition portion is connected to the main anti-collision area, the main anti-collision area and the extension portion are both linear components, and the transition portion is a rearwardly curved arc-shaped component; and

[0009] The reinforcement is connected to the side anti-collision area, so that the main anti-collision area forms a collision weak area.

[0010] In combination with the first aspect, in a possible implementation, the anti-collision beam body is provided with a through accommodating cavity along its extension path, and the reinforcement is arranged in the accommodating cavity and connected to the anti-collision beam body.

[0011] In combination with the first aspect, in a possible implementation, the reinforcement member includes a plurality of reinforcement portions distributed in sequence along the axial direction, and two adjacent reinforcement portions are spaced apart to form a collision weak area between the two adjacent reinforcement portions.

[0012] In combination with the first aspect, in a possible implementation, the reinforcement is a tubular member, and an outer wall of the reinforcement is connected to the anti-collision beam body.

[0013] In combination with the first aspect, in a possible implementation, the anti-collision beam body includes a tubular main body and a reinforcement plate arranged in the center hole of the main body, and the reinforcement plate divides the center hole of the main body into multiple independent chambers from top to bottom.

[0014] In combination with the first aspect, in a possible implementation, the reinforcement sheet has reinforcement protrusions protruding upward and / or downward.

[0015] In combination with the first aspect, in a possible implementation, the anti-collision beam assembly also includes an energy absorption box connected to the transition part, and the energy absorption box includes a mounting frame, an energy absorbing body and a connecting frame arranged in sequence from front to rear, the mounting frame is connected to the transition part, and the connecting frame is used to connect to the longitudinal beam.

[0016] In combination with the first aspect, in a possible implementation, the energy absorber includes an outer shell and a reinforcement plate arranged in the outer shell, the reinforcement plate divides the interior of the outer shell into multiple independent cavities from top to bottom, and a collapse notch is opened at the front end of the reinforcement plate.

[0017] In combination with the first aspect, in a possible implementation, the energy absorber further includes a foam aluminum reinforcement block filled in the cavity.

[0018] The beneficial effect of the front anti-collision beam assembly provided by the present invention is that: compared with the prior art, the front anti-collision beam assembly of the present invention is provided with reinforcements in the side anti-collision area, so that the strength of the side anti-collision area is higher than that of the main anti-collision area, thereby forming the main anti-collision area into a collision-weak area of ​​the anti-collision beam assembly. When the vehicle is in a side collision, the collision-weak area collapses, and the force direction of the entire vehicle shifts, thereby preventing the body parts from invading the cockpit and ensuring the safety of the personnel. In addition, when the area where the side collision occurs is close to the main anti-collision area, since the strength of the main anti-collision area is lower than that of the side anti-collision area, the main anti-collision area breaks, guiding the vehicle to deviate laterally, which is beneficial to protecting the safety of the people in the vehicle. The present invention adopts a solution of partially increasing the strength of the anti-collision beam body to form a collision-weak area in the anti-collision beam body, guiding the collision-weak area to collapse and absorb energy, or even to break, during a side collision, guiding the lateral deviation of the vehicle, avoiding the rear displacement or deformation of the anti-collision beam assembly caused by the collision, and realizing protection of the people in the vehicle.

When the vehicle is in a side collision, the collision weak area collapses, and the force direction of the entire vehicle is offset, thereby preventing the body parts from invading the cockpit and ensuring the safety of the personnel. In addition, when the area where the side collision occurs is close to the main anti-collision zone, since the strength of the main anti-collision zone is lower than that of the side anti-collision zone, the main anti-collision zone breaks, guiding the vehicle to deviate laterally, which is beneficial to protecting the safety of the people in the vehicle. The present invention adopts a solution of partially increasing the strength of the anti-collision beam body to form a collision weak area in the anti-collision beam body, guiding the collision weak area to collapse and absorb energy, or even to break, during a side collision, guiding the lateral deviation of the vehicle, avoiding the rear displacement or deformation of the anti-collision beam assembly caused by the collision, and realizing protection of the people in the vehicle.

[0029] Please also refer to Figures 1 to 4 The front impact beam assembly and vehicle provided by the present invention are now described. The front impact beam assembly includes an impact beam body 1 and a reinforcement 2. The impact beam body 1 includes a main impact zone 101 and side impact zones 102 located at both ends of the main impact zone 101 in the left and right directions. The side impact zones 102 include a transition portion 1021 and an extension portion 1022 connected in sequence. The transition portion 1021 is connected to the main impact zone 101. The main impact zone 101 and the extension portion 1022 are both linear components, while the transition portion 1021 is a rearwardly curved arc-shaped component. The reinforcement 2 is connected to the side impact zone 102, forming a collision-weakened area 103 in the main impact zone 101.

[0030] Compared to the prior art, the front impact beam assembly provided by the present invention incorporates a reinforcement member 2 in the side impact zone 102, making the side impact zone 102 stronger than the main impact zone 101. This, in turn, transforms the main impact zone 101 into a weak collision zone 103 of the impact beam assembly. In the event of a side impact, the weak collision zone 103 collapses, shifting the force applied to the vehicle, preventing body components from intruding into the cockpit and ensuring occupant safety. Furthermore, when the side impact occurs near the main impact zone 101, the main impact zone 101, because its strength is lower than that of the side impact zone 102, breaks, guiding the vehicle's lateral deflection and protecting the safety of the occupants. The present invention adopts a solution of partially increasing the strength of the anti-collision beam body 1 to form a collision weak area 103 in the anti-collision beam body 1. In the event of a side collision, the collision weak area 103 is guided to collapse and absorb energy, or even break, thereby guiding the lateral deviation of the vehicle, avoiding rear displacement or deformation of the anti-collision beam assembly caused by the collision, and protecting the people in the vehicle.

[0031] It should be noted that the distance between the anti-collision beam body 1 and the bumper is called the pedestrian protection space, and safety regulations have strict requirements for pedestrian protection space. Therefore, the main anti-collision area 101 is designed as a straight member to ensure that the pedestrian protection space meets safety regulations. If the main anti-collision area 101 is designed as a curved member, it will encroach on the pedestrian protection space.

[0032] Optionally, a plurality of reinforcement members 2 are provided, and the reinforcement members 2 are arranged in a one-to-one correspondence with the side impact protection areas 102 .

[0033] Optionally, the reinforcement 2 is fitted to the side anti-collision area 102 to increase the contact area with the side anti-collision area 102 and improve the firmness of the connection.

[0034] In some embodiments, see Figures 1 to 2 The anti-collision beam body 1 is provided with a through accommodating cavity along its own extension path, and the reinforcement 2 is arranged in the accommodating cavity and connected to the anti-collision beam body 1.

[0035] In this embodiment, the reinforcement 2 is arranged in the accommodating cavity without occupying the space outside the anti-collision beam body 1, which not only avoids interference with other components in the vehicle, but also avoids the problem of uneven strength of the anti-collision beam body 1 in the front and rear directions or the up and down directions caused by arranging the reinforcement 2 on one side of the anti-collision beam body 1.

[0036] Optionally, the reinforcement 2 is one of a plate-shaped component, a block-shaped component and a tubular component.

[0037] In some embodiments, see Figure 3 The reinforcement member 2 includes a plurality of reinforcement portions 201 distributed in sequence along the axial direction, and two adjacent reinforcement portions 201 are spaced apart so that a collision weak area 103 is formed between the two adjacent reinforcement portions 201 .

[0038] The solution in this embodiment not only forms a collision weak area 103 in the main anti-collision area 101, but also forms a collision weak area 103 in the side anti-collision area 102 corresponding to the area between two adjacent reinforcement parts 201, thereby guiding the anti-collision beam body 1 to have the corresponding collision weak area 103 to collapse, absorb energy or break no matter where a side collision occurs, which is more conducive to protecting the safety of people in the car.

[0039] Optionally, the interval between two adjacent reinforcement parts 201 is 20-30 mm to ensure the safety performance of the vehicle during a 25% offset collision.

[0040] Optionally, the reinforcement 2 includes two reinforcement portions 201, with the outer reinforcement portion 201 occupying 20-22% of the entire length of the anti-collision beam body 1. The inner reinforcement 2 is mainly used to improve the safety of the vehicle in the event of a 40% offset collision. Under the 40% offset collision condition, the anti-collision beam body 1 collapses in the weak collision area 103, causing the force direction of the entire vehicle to shift, and the front cabin collapses as a whole to absorb energy, thereby ensuring the safety of the occupants. The inner reinforcement portion 201 occupies 11-13% of the entire length of the anti-collision beam body 1.

[0041] In some embodiments, see Figure 2 The reinforcement 2 is a tubular component, and the outer wall of the reinforcement 2 is connected to the anti-collision beam body 1.

[0042] Because the reinforcement 2 is a tubular member, it offers superior strength and rigidity compared to plate-like members. This allows for a greater strength difference between the main impact zone 101 and the side impact zone 102 of the anti-collision beam body 1, without increasing the thickness of the reinforcement 2. Furthermore, when the vehicle body is subjected to external forces, the central hole of the reinforcement 2 collapses to absorb energy, guiding the vehicle's lateral deflection and improving safety in side collisions.

[0043] In some embodiments, see Figure 2The anti-collision beam body 1 includes a tubular main body and a reinforcing sheet 104 arranged in the central hole of the main body. The reinforcing sheet 104 divides the central hole of the main body into a plurality of independent chambers from top to bottom.

[0044] The reinforcement sheet 104 can increase the strength of the main body and improve the ability of the anti-collision beam body to resist external forces. After the reinforcement sheet 104 divides the central hole of the main body into multiple independent chambers, the deformation capacity of each chamber is reduced, which can more effectively resist collision forces.

[0045] In some embodiments, see Figure 2 , the reinforcing sheet 104 has reinforcing protrusions protruding upward and / or downward.

[0046] Reinforcement protrusions are provided on the reinforcing sheet 104 so that the reinforcing sheet 104 forms a curved structure. Compared with the traditional flat plate structure, the anti-collision beam body 1 can collapse more fully during a collision, thereby increasing the energy absorption of the anti-collision beam body 1 and ensuring personnel safety.

[0047] In some embodiments, see Figures 3 and 4 The anti-collision beam assembly also includes an energy absorption box 3 connected to the transition portion 1021. The energy absorption box 3 includes a mounting frame 301, an energy absorbing body 302 and a connecting frame 303 arranged in sequence from front to rear. The mounting frame 301 is connected to the transition portion 1021, and the connecting frame 303 is used to connect to the longitudinal beam.

[0048] When the vehicle collides, the energy absorption box 3 collapses to absorb energy and transmits the collision force to the rear of the vehicle, thereby avoiding the problem of local force concentration.

[0049] Optionally, the mounting bracket 301 protrudes rearward, forming a slot on the front side to accommodate the anti-collision beam. The energy-absorbing body 302 has a mounting slot, into which the protruding portion of the mounting bracket 301 is inserted. This embodiment increases the contact area between the mounting bracket 301 and the anti-collision beam body 1, and between the energy-absorbing body 302 and the mounting bracket 301, thereby improving the reliability of the connection.

[0050] In some embodiments, see Figure 4 The energy absorbing body 302 includes a shell 3022 and a reinforcing plate 3021 disposed in the shell 3022 . The reinforcing plate 3021 divides the interior of the shell 3022 into a plurality of independent cavities from top to bottom, and a collapse notch 3024 is opened at the front end of the reinforcing plate 3021 .

[0051] A crush notch 3024 is provided on the front side of the reinforcing plate 3021 to ensure that the energy absorption box 3 collapses outwards under a 25% offset collision condition, thereby guiding the vehicle to generate lateral movement force, avoiding direct collision between the vehicle and obstacles, and increasing the safety of people in the vehicle.

[0052] Optionally, the crush notch 3024 is a rectangular notch with a length ranging from 50-70 mm and a width ranging from 25-35 mm, and the length of the crush notch 3024 in the front-to-back direction accounts for 12.5%-17.5% of the entire length of the crash box 3. This arrangement can achieve outward crushing of the crash box 3 during a side impact while ensuring the strength of the crash box 3.

[0053] In some embodiments, see Figure 4 The energy absorbing body 302 further includes a foam aluminum reinforcement block 3023 filled in the cavity.

[0054] The main function of the foam aluminum reinforcement block 3023 is to increase the energy absorption capacity of the energy absorption box 3. When the collapse notch 3024 of the energy absorption box 3 collapses, more energy is absorbed by the collapse of the rear foam aluminum reinforcement block 3023, which can absorb more collision energy during a low-speed collision and reduce the damage to the longitudinal beam to a greater extent.

[0055] Optionally, the foam aluminum reinforcement block 3023 is bonded to the outer shell 3022 .

[0056] Based on the same inventive concept, the present invention further provides a vehicle comprising the above-mentioned front anti-collision beam assembly.

[0057] The vehicle provided by the present invention utilizes the aforementioned front crash beam assembly. A reinforcement member 2 is provided in the side crash zone 102, making the side crash zone 102 stronger than the main crash zone 101. This, in turn, forms the main crash zone 101 into a weak collision zone 103 of the crash beam assembly. In the event of a side collision, the weak collision zone 103 collapses, shifting the force applied to the vehicle, preventing body components from intruding into the cockpit and ensuring occupant safety. Furthermore, when the side collision occurs near the main crash zone 101, the main crash zone 101, because its strength is lower than that of the side crash zone 102, breaks, guiding the vehicle's lateral deflection and thus protecting the safety of the occupants. The present invention adopts a solution of partially increasing the strength of the anti-collision beam body 1 to form a collision weak area 103 in the anti-collision beam body 1. In the event of a side collision, the collision weak area 103 is guided to collapse and absorb energy, or even break, thereby guiding the lateral deviation of the vehicle, avoiding rear displacement or deformation of the anti-collision beam assembly caused by the collision, and protecting the people in the vehicle.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
