Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle body structure, an A-pillar reinforcement assembly, and a vehicle. Background Technology

[0002] In a 25% small offset crash test, the A-pillar of the vehicle body must not exhibit any bending. Due to the design of the vehicle's front engine compartment, this is essentially impossible to alter. The A-pillar reinforcement plate serves as a crucial force transmission path to resist bending deformation, making improvements to the A-pillar reinforcement plate particularly important.

[0003] Traditional A-pillar reinforcement plates can transfer the impact force from the front to the rear of the vehicle during a collision. The impact force is mainly distributed to the upper beam of the vehicle body and the B-pillar through three main force transmission paths. However, the bending resistance and transmission performance of the A-pillar reinforcement plates are limited. Therefore, how to improve the force transmission efficiency and deformation resistance of the A-pillar reinforcement plates in a 25% small offset collision is an urgent problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to solve the aforementioned technical problems by providing a vehicle body structure, an A-pillar reinforcement plate assembly, and a vehicle. This allows for the installation of reinforcing ribs in the A-pillar reinforcement plate, increasing the force transmission path and improving its force transmission efficiency and resistance to deformation. To achieve the above objective, the technical solution of this utility model is as follows:

[0005] The vehicle body structure includes an A-pillar upper reinforcing plate and a B-pillar reinforcing plate. The B-pillar reinforcing plate is disposed at the rear end of the A-pillar upper reinforcing plate. The A-pillar upper reinforcing plate includes reinforcing ribs, and the B-pillar reinforcing plate includes a first force-transmitting rib and a second force-transmitting rib. The reinforcing ribs are respectively connected to the first force-transmitting rib and the second force-transmitting rib.

[0006] Specifically, the first force transmission rib extends toward the rear of the upper reinforcing plate of the A-pillar, and the second force transmission rib extends toward the lower part of the upper reinforcing plate of the A-pillar.

[0007] Specifically, the top of the B-pillar reinforcement plate is connected to the upper reinforcement plate of the A-pillar. The B-pillar reinforcement plate is located near the outer side of the vehicle body, and the upper reinforcement plate of the A-pillar is located near the inner side of the vehicle body. A gap is formed between the top of the B-pillar reinforcement plate and the upper reinforcement plate of the A-pillar.

[0008] Specifically, the A-pillar reinforcement plate also includes a connected protrusion and a support, and the protrusion has the reinforcing rib on the side near the support.

[0009] Specifically, the B-pillar reinforcement plate also includes a first connecting part and a second connecting part connected together. The first connecting part has a first force transmission rib and a second force transmission rib on the side near the second connecting part. The first connecting part abuts against the protrusion and the second connecting part abuts against the support part.

[0010] Specifically, the first connecting portion extends toward the rear of the upper reinforcing plate of the A-pillar, and the second connecting portion extends toward the lower part of the upper reinforcing plate of the A-pillar.

[0011] The A-pillar reinforcement plate assembly includes an A-pillar reinforcement plate, an A-pillar inner plate, and an A-pillar fixing part. The A-pillar reinforcement plate and the A-pillar inner plate are connected to form an inner cavity. The A-pillar fixing part is located in the inner cavity and abuts against the A-pillar reinforcement plate, and / or the A-pillar fixing part abuts against the A-pillar inner plate.

[0012] Specifically, one end of the fixing part on the A-pillar is connected to the reinforcing plate on the A-pillar and the inner plate on the A-pillar, and / or the other end of the fixing part on the A-pillar is connected to the reinforcing plate on the A-pillar.

[0013] Specifically, the fixing part on the A-pillar is a tubular structure.

[0014] The vehicle includes the aforementioned body structure or the aforementioned A-pillar reinforcement assembly.

[0015] Compared with existing technologies, the beneficial effects of this utility model's vehicle body structure, A-pillar reinforcement plate assembly, and vehicle are mainly reflected in:

[0016] The reinforcing ribs are connected to the first and second force transmission ribs respectively. The reinforcing ribs can quickly transfer the force of the A-pillar reinforcing plate to the first and second force transmission ribs of the B-pillar reinforcing plate in the offset collision condition, thereby efficiently transferring the force to all parts of the vehicle body, improving the bending resistance and transmission performance of the A-pillar reinforcing plate, resisting the bending phenomenon in the 25% small offset collision condition, and improving the overall safety protection capability of the vehicle body structure.

[0034] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. In the illustrations, "front," "rear," and "bottom" specifically refer to the front, rear, and bottom of the vehicle body.

[0035] Example 1

[0036] This embodiment provides a vehicle body structure, including an A-pillar reinforcement plate 1 and a B-pillar reinforcement plate 2. The B-pillar reinforcement plate 2 is disposed at the rear end of the A-pillar reinforcement plate 1 and has a generally T-shaped structure. The top of the B-pillar reinforcement plate 2 is abutted against the A-pillar reinforcement plate 1, and the bottom of the B-pillar reinforcement plate 2 extends downward toward the A-pillar reinforcement plate 1. In this embodiment, the front end of the A-pillar reinforcement plate 1 is positioned facing forward of the vehicle body, and the rear end of the A-pillar reinforcement plate 1 is positioned facing rearward of the vehicle body. The rear end of the A-pillar reinforcement plate 1 is connected to a vehicle body upper beam 8. The A-pillar reinforcement plate 1 is positioned near the inner side of the vehicle body, and the B-pillar reinforcement plate 2 is positioned near the outer side of the vehicle body. In a 25% small offset collision, the force can be transmitted from the A-pillar reinforcement plate 1 to the vehicle body upper beam 8 and the B-pillar reinforcement plate 2.

[0037] The rear end of the B-pillar reinforcing plate 2 can be flush with the rear end of the A-pillar reinforcing plate 1, or it can be close to the rear end of the A-pillar reinforcing plate, without affecting the force transmission between the A-pillar reinforcing plate 1 and the upper beam 8 of the vehicle body. To improve the force transmission efficiency and deformation resistance of the A-pillar reinforcing plate 1, improvements are made to both the A-pillar reinforcing plate 1 and the B-pillar reinforcing plate 2, as detailed below:

[0038] like Figures 1-4 As shown, the A-pillar reinforcement plate 1 includes a reinforcing rib 11, and the B-pillar reinforcement plate 2 includes a first force transmission rib 23 and a second force transmission rib 24. The reinforcing rib 11 is connected to the first force transmission rib 23 and the second force transmission rib 24 respectively. The first force transmission rib 23 extends toward the rear of the A-pillar reinforcement plate 1, and the second force transmission rib 24 extends toward the lower part of the A-pillar reinforcement plate 1.

[0039] The reinforcing rib 11 is connected to the first force transmission rib 23 to form a first force guiding path 41 that transmits force from the upper reinforcing plate 1 of column A to the rear of the reinforcing plate 2 of column B. The reinforcing rib 11 is connected to the second force transmission rib 24 to form a second force guiding path 42 that transmits force from the upper reinforcing plate 1 of column A to the lower part of the reinforcing plate 2 of column B.

[0040] The first force guiding path 41 can transfer the force of the A-pillar reinforcement plate 1 from the rear end of the B-pillar reinforcement plate 2 to the upper beam 8 of the vehicle body. The second force guiding path 42 can transfer the force of the A-pillar reinforcement plate 1 to the B-pillar reinforcement plate 2 below, i.e., to the B-pillar. The first force guiding path 41 and the second force guiding path 42 are additionally set on the original main force transmission path of the A-pillar reinforcement plate 1, which can quickly and efficiently transfer the force in the offset collision condition to all parts of the vehicle body, improve the bending resistance and transmission performance of the A-pillar reinforcement plate 1, resist the bending phenomenon in the 25% small offset collision condition, and thus improve the safety protection capability of the vehicle body structure. At the same time, the first force guiding path 41 and the second force guiding path 42 can be formed without the need for additional parts assembly. The reinforcing rib 11 on the A-pillar reinforcement plate 1 and the first force transmission rib 23 and the second force transmission rib 24 on the B-pillar reinforcement plate 2 are realized by sheet metal forming process, which has the characteristics of lightweight.

[0041] In one embodiment, the reinforcing plate 1 on column A and the reinforcing plate 2 on column B are connected to form the main force transmission path, and the reinforcing ribs 11 on the reinforcing plate 1 on column A are arranged in the same direction as part of the main force transmission path.

[0042] There are three main force transmission paths: a first main force transmission path 43, a second main force transmission path 44, and a third main force transmission path 45. The first and second main force transmission paths 43 and 44 both transmit force from the upper A-pillar reinforcing plate 1 to the rear of the B-pillar reinforcing plate 2, that is, the first and second main force transmission paths 43 and 44 both transmit force to the upper beam 8 of the vehicle body. The third main force transmission path 45 transmits force from the upper A-pillar reinforcing plate 1 to the lower part of the B-pillar reinforcing plate 2.

[0043] Specifically, the reinforcing rib 11 is located between the second main force transmission path 44 and the third main force transmission path 45, that is, the first force guiding path 41 and the second force guiding path 42 are both located between the second main force transmission path 44 and the third main force transmission path 45; when the reinforcing rib 11 of the A-pillar reinforcing plate 1 transmits the force, the force on the B-pillar reinforcing plate 2 is distributed into two branches, that is, the first force guiding path 41 and the second force guiding path 42 are formed. The increased force guiding path can effectively improve the force transmission efficiency, and at the same time, improve the bending resistance of the A-pillar reinforcing plate 1 and the B-pillar reinforcing plate 2.

[0044] In one embodiment, the top of the B-pillar reinforcing plate 2 is connected to the A-pillar upper reinforcing plate 1, and a gap 14 is formed between the top of the B-pillar reinforcing plate 2 and the A-pillar upper reinforcing plate 1.

[0045] The aforementioned B-pillar reinforcing plate 2 has a roughly T-shaped structure. The top of the B-pillar reinforcing plate 2 is connected to the upper A-pillar reinforcing plate 1, and the bottom of the B-pillar reinforcing plate 2 extends downward toward the upper A-pillar reinforcing plate 1. A gap 14 is formed between the top of the B-pillar reinforcing plate 2 and the upper A-pillar reinforcing plate 1, that is, a cavity is formed between the top of the B-pillar reinforcing plate 2 and the upper A-pillar reinforcing plate 1. The cavity is conducive to the effective transmission of force and at the same time improves the bending resistance and energy absorption effect of the B-pillar reinforcing plate 2.

[0046] In one embodiment, the A-pillar reinforcement plate 1 further includes a protrusion 12 and a support 13 connected together, and the protrusion 12 has a reinforcing rib 11 on the side near the support 13.

[0047] The front end of the A-pillar reinforcing plate 1 is provided with a resultant plate 15, which is an integral plate structure with the A-pillar reinforcing plate 1. The resultant plate 15 has a first branch force transmission path 46 and a second branch force transmission path 47 formed by ribs. Both the first branch force transmission path 46 and the second branch force transmission path 47 are connected to the force guiding path of the reinforcing rib 11. The first branch force transmission path 46 can be merged or separated from the second main force transmission path 44, and the second branch force transmission path 47 can be merged or separated from the third main force transmission path 45. The front end of the resultant plate 15 is connected to the main body of the A-pillar, so that the force transmitted from the main body of the A-pillar is quickly transmitted to the A-pillar reinforcing plate 1 through the resultant plate 15.

[0048] Specifically, the protrusion 12 includes a first protruding plate 31, a second protruding plate 32, and a third protruding plate 33 connected in sequence. The protrusion 12 has a roughly Z-shaped structure. The connection points of the first protruding plate 31 and the second protruding plate 32, the connection points of the second protruding plate 32 and the third protruding plate 33, and the connection points of the third protruding plate 33 and the support part 13 all form R-angles. The third protruding plate 33 has a reinforcing rib 11, which also has an R-angle. The reinforcing rib 11 forms a new force guiding path along the A-pillar upper reinforcing plate 1, that is, the merged path of the first force guiding path 41 and the second force guiding path 42. The reinforcing rib 11 is formed on the A-pillar upper reinforcing plate 1, avoiding the need for additional components, effectively reducing the weight of the A-pillar upper reinforcing plate 1, and improving the bending resistance of the A-pillar upper reinforcing plate 1.

[0049] In one embodiment, the B-pillar reinforcing plate 2 further includes a first connecting portion 21 and a second connecting portion 22 connected together. The first connecting portion 21 has a first force transmission rib 23 and a second force transmission rib 24 on the side near the second connecting portion 22. The first connecting portion 21 abuts against the protrusion 12, and the second connecting portion 22 abuts against the support portion 13.

[0050] In this configuration, the first connecting portion 21 connects to the second protruding plate 32 of the protruding portion 12; both the first force transmission rib 23 and the second force transmission rib 24 have a gap 14 with the upper reinforcing plate 1 of the A-pillar; a portion of the second connecting portion 22 connects to the supporting portion 13, and the other portion of the second connecting portion 22 extends downward toward the upper reinforcing plate 1 of the A-pillar; the connection between the B-pillar reinforcing plate 2 and the upper reinforcing plate 1 of the A-pillar can be fixed by welding, and the edges of the B-pillar reinforcing plate 2 are stably fixed to the upper reinforcing plate 1 of the A-pillar by welding, ensuring that the force is smoothly transmitted along the force transmission path during a collision, and improving the reliability of the connection between the B-pillar reinforcing plate 2 and the upper reinforcing plate 1 of the A-pillar. Correspondingly, the first connecting portion 21 connects to the second protruding plate 32 to form a first main force transmission path 43, the first connecting portion 21 connects to the third protruding plate 33 to form a second main force transmission path 44, and the second connecting portion 22 connects to the supporting portion 13 to form a third main force transmission path 45.

[0051] In one embodiment, the second force transmission rib 24 extends from the first force transmission rib 23 toward the lower part of the upper reinforcing plate 1 of the A-pillar. The first connecting portion 21 extends toward the rear of the upper reinforcing plate 1 of the A-pillar, and the second connecting portion 22 extends toward the lower part of the upper reinforcing plate 1 of the A-pillar.

[0052] The second force transmission rib 24 can be two ribs. One second force transmission rib 24 has its end connected to the front end of the first force transmission rib 23, extending towards the front of the vehicle body. The other second force transmission rib 24 has its end connected to the rear end of the first force transmission rib 23, extending towards the rear of the vehicle body. The second connecting part 22 corresponds to the arrangement trajectory of the second force transmission rib 24. The second connecting part 22 has an arc-shaped structure. The end of one second connecting part 22 is flush with the front end of the first connecting part 21, and the end of the other second connecting part 22 is flush with the rear end of the first connecting part 21. The second force transmission rib 24 and the second connecting part 22 of the B-pillar reinforcing plate 2 can smoothly transmit the force towards the lower part of the A-pillar reinforcing plate 1. The force transmission of each guiding path and each force transmission path is smooth and efficient.

[0053] Example 2

[0054] This embodiment provides an A-pillar reinforcement plate assembly, such as... Figures 5-8 As shown, the A-pillar reinforcement plate 1 in the above embodiment is included. The A-pillar reinforcement plate assembly also includes an A-pillar inner plate 5 and an A-pillar fixing part 6. The A-pillar reinforcement plate 1 and the A-pillar inner plate 5 are connected to form an inner cavity 51. The A-pillar fixing part 6 is located in the inner cavity 51. The A-pillar fixing part 6 abuts against the A-pillar reinforcement plate 1 and / or the A-pillar fixing part 6 abuts against the A-pillar inner plate 5.

[0055] The A-pillar reinforcement panel assembly is configured to connect with the side outer panel 7, which is positioned on the outer side of the vehicle body relative to the A-pillar reinforcement panel assembly.

[0056] In one embodiment, one end of the fixing part 6 on the A-pillar is connected to the reinforcing plate 1 on the A-pillar and the inner plate 5 on the A-pillar, and / or the other end of the fixing part 6 on the A-pillar is connected to the reinforcing plate 1 on the A-pillar.

[0057] The fixing part 6 on the A-pillar can divide the inner cavity 51 into two sub-cavities, thereby improving the force transmission stability of the A-pillar reinforcement plate assembly and having a better collision energy absorption effect. The fixing part 6 on the A-pillar can be welded and fixed to the A-pillar reinforcement plate 1.

[0058] The A-pillar fixing part 6 can also abut against the A-pillar reinforcing plate 1, and at least partially adhere to the A-pillar reinforcing plate 1; the A-pillar fixing part 6 can also abut against the A-pillar inner plate 5, and at least partially adhere to the A-pillar inner plate 5; the A-pillar fixing part 6 can be connected and formed with the A-pillar reinforcing plate 1 and / or the A-pillar inner plate 5 by a stacking stamping method, effectively increasing the connection strength and rigidity of the A-pillar reinforcing plate 1 and / or the A-pillar inner plate 5. When the A-pillar fixing part 6 abuts against the A-pillar reinforcing plate 1, the A-pillar fixing part 6 is set close to the reinforcing rib 11, and the force of the reinforcing rib 11 can also be quickly dispersed and transmitted in the A-pillar fixing part 6, further improving the bending resistance of the A-pillar reinforcing plate assembly.

[0059] In one embodiment, the fixing part 6 on the A-pillar is a tubular structure, and the fixing part 6 on the A-pillar is fixed to the outer wall of the reinforcing plate 1 on the A-pillar by welding; the fixing part 6 on the A-pillar can be a hollow tubular structure, and the fixing part 6 on the A-pillar is spaced apart from the inner plate 5 on the A-pillar. The fixing part 6 on the A-pillar improves the connection strength and support performance of the reinforcing plate assembly on the A-pillar, and further improves the energy absorption effect of the reinforcing plate assembly on the A-pillar.
