Description

Technical Field

[0001] This application relates to the technical field of automobiles, and particularly to an A-pillar structure and a vehicle. Background Art

[0002] In the body frame structure, the lower part of the A-pillar, as the "cornerstone" at the front of the passenger compartment, shoulders the role of resisting frontal or side collisions and key joints of the whole vehicle. At the same time, it provides the installation points for the front door and the instrument panel frame, and is the last line of defense for the front-row occupants. The existing lower part of the A-pillar is provided with an energy-absorbing cavity, which deforms the lower part of the A-pillar during a collision to reduce the deformation of the passenger compartment. However, due to the easy deformation or breakage of the A-pillar, the front wheel hits and moves backward, invading the lower part of the A-pillar and the passenger compartment, occupying the living space of the occupants. And due to the insufficient strength of the lower part of the A-pillar, the instrument panel frame moves backward, squeezing the living space of the front-row occupants, resulting in the deformation or tearing of the front door hinge installation point and causing the door to be torn open.

[0014] One end of the lower mounting plate is fixed to the lower inner panel section through a support plate, and the other end of the lower mounting plate extends to the sill beam and is fixedly connected to the sill beam.

Along the direction from the rear section of the wheelhouse side beam to the A-pillar main body, the distance between the first edge and the second edge gradually increases. In this way, the decomposition of the collision force can be effectively guided through the smoothly transitioned first edge and second edge, making the force transmission smoother, avoiding structural deformation and tearing caused by excessive local stress, and also avoiding the invasion of the A-pillar by the rearward movement of the front wheel impact, which may encroach on the occupant survival space.

[0034] To make the objectives, technical solutions and advantages of the present application clearer and more understandable, the following further elaborates on the present application in detail with reference to specific embodiments and the accompanying drawings.

[0035] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the ordinary meanings understood by those with ordinary skills in the field to which the present application belongs.

Words such as "include" or "comprise" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. Words such as "connect" or "be connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Upper", "lower", "left", "right", etc. are only used to represent relative position relationships, and when the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0036] As described in the background art, as Figure 1 shown, the existing A-pillar structure includes the rear section 1 of the wheelhouse side beam, the A-pillar main body 10 and the threshold beam 4. The connection between the rear section 1 of the wheelhouse side beam and the A-pillar main body 10 is a vertical connection (visible Figure 1The rear section 1 of the wheelhouse side beam and the side connection of the A-pillar main body 10 are all right angles), and the sill beam 4 is connected to the side wall of the A-pillar main body 10, and the reinforcing beam 5 is arranged inside the sill beam 4. Since the inside of the A-pillar main body 10 is a cavity structure, when the front wheel hits and moves backward and invades the A-pillar, the rear section 1 of the wheelhouse side beam will transmit the impact force to the front end of the A-pillar main body 10. Since the connection between the rear section 1 of the wheelhouse side beam and the A-pillar main body 10 is a vertical connection, the force transmission is not smooth, which easily causes the deformation or breakage of the A-pillar main body. When the impact force is transmitted to the vehicle body, due to the insufficient strength of the lower part of the A-pillar, the instrument panel skeleton moves backward and squeezes the living space of the front row occupants, which may threaten the personal safety of the occupants, and will also cause the deformation or tearing of the front door hinge installation point, resulting in the door being torn open.

[0037] To solve the above problems, referring to Figure 2 and Figure 3 This application provides an A-pillar structure, which includes a rear section 1 of a wheelhouse side beam and an A-pillar main body 10. The rear section 1 of the wheelhouse side beam is connected to the side of the A-pillar main body 10. The top surface of the rear section 1 of the wheelhouse side beam and the top surface of the A-pillar main body 10 are sequentially connected to form a first outer edge 01 of the A-pillar structure. The bottom surface of the rear section 1 of the wheelhouse side beam and the side of the A-pillar main body 10 are sequentially connected to form a second outer edge 02 of the A-pillar structure. Along the direction from the rear section 1 of the wheelhouse side beam to the A-pillar main body 10, the distance between the first outer edge 01 and the second outer edge 02 gradually increases.

[0038] Specifically, the A-pillar structure in this application takes the left A-pillar of the whole vehicle as an example. The side of the A-pillar main body 10 refers to the side of the A-pillar main body 10 close to the vehicle head, and the rear section 1 of the wheelhouse side beam is connected to the side of the A-pillar main body 10. Further, the rear section 1 of the wheelhouse side beam is connected to the upper part of this side of the A-pillar main body 10, so that the top surface 011 of the rear section of the wheelhouse side beam can be better connected to the top surface 012 of the A-pillar main body.

[0039] As Figure 2 can be seen, the top surface 011 of the rear section of the wheelhouse side beam and the top surface 012 of the A-pillar main body are sequentially connected to form the first outer edge 01 of the A-pillar structure. It can be understood that the connection surface between the top surface 011 of the rear section of the wheelhouse side beam and the top surface 012 of the A-pillar main body is a smoothly transitioning curved surface, that is, the first outer edge 01 is a smooth curved surface. Exemplarily, the first outer edge 01 is an arc-shaped curved surface.

[0040] The bottom surface 021 of the rear section of the wheelhouse side beam and the side surface 022 of the A-pillar main body are sequentially connected to form the second outer edge 02 of the A-pillar structure. It can be understood that the connection surface between the bottom surface 021 of the rear section of the wheelhouse side beam and the side surface 022 of the A-pillar main body is a smoothly transitioning curved surface, that is, the second outer edge 02 is a smooth curved surface. Exemplarily, the second outer edge 02 is an arc-shaped curved surface.

[0041] Along the direction from the rear section 1 of the wheelhouse side beam to the A-pillar main body 10, the distance between the first outer edge 01 and the second outer edge 02 gradually increases, that is, a flaring structure is formed between the first outer edge 01 and the second outer edge 02. Since a flaring structure is formed between the first outer edge 01 and the second outer edge 02, the first outer edge 01 and the second outer edge 02 can gradually grade the impact force, effectively guiding the impact force to smoothly transfer from the rear section 1 of the wheelhouse side beam to the A-pillar main body 10, avoiding excessive local stress of the A-pillar main body 10 caused by uneven force transmission, ultimately resulting in deformation and tearing of the A-pillar structure, and even encroaching on the survival space of the front-row occupants.

[0042] By designing the side connection between the rear section 1 of the wheelhouse side beam and the A-pillar main body 10 of the A-pillar structure, when the front wheel impacts and moves rearward to invade the A-pillar, the rear section 1 of the wheelhouse side beam and the A-pillar main body 10 can be stressed in sequence, guiding the decomposition of the collision force, making the force transmission smoother, avoiding structural deformation and tearing caused by excessive local stress, and also avoiding the encroachment on the occupant survival space caused by the rearward movement and invasion of the front wheel hitting the A-pillar.

[0043] Furthermore, the area of the side surface of the rear section 1 of the wheelhouse side beam close to the vehicle head is smaller, and the area of the side surface of the rear section 1 of the wheelhouse side beam far from the vehicle head is larger, thus forming a flaring structure. The area of the side surface of the rear section 1 of the wheelhouse side beam far from the vehicle head is smaller than the side surface of the A-pillar main body 10, so that the rear section 1 of the wheelhouse side beam bears the impact force first with a small-area side surface, then the impact force is gradually transmitted to the larger-area side surface, and then continues to be transmitted to the side surface of the A-pillar main body 10 with an even larger side area, thereby gradually dispersing the impact force, effectively guiding the impact force to smoothly transfer from the rear section 1 of the wheelhouse side beam to the A-pillar main body 10, and avoiding deformation and tearing of the A-pillar structure.

[0044] As Figure 4 and Figure 5 shown, the rear section 1 of the wheelhouse side beam includes an inner rear panel 11 and an outer rear panel 12 that are snap-connected; the A-pillar main body includes an A-pillar inner panel 3 and an A-pillar outer panel 2 that are snap-connected. The inner rear panel 11 is fixedly connected to the A-pillar inner panel 3, and the outer rear panel 12 is fixedly connected to the A-pillar outer panel 2. Among them, the top surface of the inner rear panel 11 and the top surface of the A-pillar inner panel 3 are connected in sequence, the bottom surface of the inner rear panel 11 and the side surface of the A-pillar inner panel 3 are connected in sequence, the top surface of the outer rear panel 12 and the top surface of the A-pillar outer panel 2 are connected in sequence, and the bottom surface of the outer rear panel 12 and the side surface of the A-pillar outer panel are connected in sequence. In this way, after the front wheel impacts, the collision force is decomposed from the inner rear panel 11 of the rear section 1 of the wheelhouse side beam to the A-pillar inner panel 3, and the collision force is decomposed from the outer rear panel 12 to the A-pillar outer panel 2, which can effectively guide the decomposition of the collision force, reduce the collision force borne by the occupant compartment, and thus reduce the deformation of the occupant compartment.

[0045] The connecting surface between the top surface of the rear inner panel 11 and the top surface of the A-pillar inner panel 3 is arc-shaped, and the connecting surface between the bottom surface of the rear inner panel 11 and the side surface of the A-pillar inner panel 3 is arc-shaped. Along the direction from the rear section 1 of the wheelhouse side beam to the A-pillar main body 10, the distance between the two arc-shaped connecting surfaces gradually increases. It can be understood that the distance between the two connecting surfaces gradually increases in a flared shape. In this way, after the front wheel impacts, the force received by the rear section 1 of the wheelhouse side beam gradually decomposes towards the A-pillar main body 10, and the force is received by a small area of the rear section 1 of the wheelhouse side beam and gradually decomposes to a large area of the A-pillar main body 10, making the force transmission path gradually increase from small to large, realizing the buffering of the impact force, effectively decomposing the impact force, reducing the impact force received by the passenger compartment, and reducing the deformation of the passenger compartment. Moreover, the two arc-shaped connecting lines make the process of decomposing the force smoother, without obstruction, and can more effectively decompose the impact force, reducing the impact force received by the passenger compartment.

[0046] Furthermore, as Figure 4 shown, the A-pillar outer panel 2 includes a spliced upper outer panel 21 and a lower outer panel 22, and the splicing line 20 between the upper outer panel 21 and the lower outer panel 22 is located between the top surface and the bottom surface of the rear section 1 of the wheelhouse side beam. In this way, after the front wheel impacts, the collision force is decomposed from the rear outer panel 12 of the rear section 1 of the wheelhouse side beam to the A-pillar outer panel 2. The splicing line 20 of the A-pillar outer panel 2 is located between the heights of the rear section 1 of the wheelhouse side beam, which can enable the A-pillar outer panel 2 to decompose the collision force evenly. Among them, due to process limitations, the cross-sectional size of the upper outer panel 21 is smaller than that of the lower outer panel 22. In order to make the cross-sectional size of the upper outer panel 21 correspond to that of the lower outer panel 22, the material or thickness of the upper outer panel 21 can be increased so that the cross-sectional sizes of the upper outer panel 21 and the lower outer panel 22 are almost the same, and preferably, the cross-sectional size of the upper outer panel 21 is equal to that of the lower outer panel 22, so that the A-pillar outer panel 2 can be more evenly stressed.

[0047] Furthermore, as Figure 3 shown, the top surface of the rear outer panel 12 of the rear section 1 of the wheelhouse side beam is connected to the A-pillar outer panel 2 by multiple surfaces led out from one surface. In this way, it can achieve a smooth transition and decompose the collision force in layers, making the decomposition effect of the collision force better, avoiding the fracture of the collision force and the concentration of the force, and increasing the risk of extrusion deformation of the passenger compartment.

[0048] In some embodiments, as Figure 6 shown, a chamber 101 is provided between the rear inner panel 11 and the rear outer panel 12, and the chamber 101 is provided with an outlet 1011 towards the sill beam 4.

[0049] In this embodiment, a recessed portion 23 is provided at a position where the A-pillar outer panel 2 is close to the rear outer panel 12, and the recessed portion 23 is communicated with the outlet 1011.

[0050] Specifically, as Figure 6As shown, there is a chamber 101 (exemplarily the first chamber 101) between the rear inner panel 11 and the rear outer panel 12, and the chamber 101 is provided with an outlet 1011 which is arranged towards the sill beam 4. It can be understood that the outlet 1011 of the chamber 101 is arranged towards the ground, and there is a recess 23 at the position where the A-pillar outer panel 2 is close to the rear outer panel 12, and the recess 23 communicates with the outlet 1011. In this way, when the vehicle wipes the windshield, the windshield washer fluid remaining on the vehicle can flow out to the ground through the outlet 1011 and the recess 23. Or when it rains, the water remaining between the vehicle glass and the engine hood can flow out through the outlet 1011 and the recess 23. This prevents water from remaining on the vehicle and causing vehicle corrosion. Among them, the wiper cover between the engine hood and the front vehicle glass is an arc-shaped groove, and the chamber 101 is also provided with a through hole corresponding to the arc-shaped groove, so that the windshield washer fluid or rainwater on the wiper cover can flow into the chamber 101 and flow out through the outlet 1011, ensuring that there is no water stored in the vehicle and preventing vehicle corrosion. Further, the outlet 1011 can also ensure smooth liquid drainage after the electrophoresis of the A-pillar structure in the painting workshop during the production stage.

[0051] In some embodiments, as Figure 6 and Figure 11 shown, the A-pillar structure further includes a sill beam 4, and one end of the sill beam 4 extends into the A-pillar main body 10 and is connected to the A-pillar main body 10.

[0052] Specifically, as Figure 9 shown, one end of the sill beam 4 extends into the A-pillar main body 10 and is connected to the A-pillar main body 10. It can be understood that the extending end of the sill beam 4 is connected to the side wall of the A-pillar main body 10 adjacent to the rear section of the wheel arch side beam 1. Exemplarily, as Figure 10 shown, the length L1 of the sill beam 4 extends into the A-pillar main body 10, and the length L1 of the sill beam 4 coincides with the length L1 of the A-pillar inner panel 3. It can also be understood that the sill beam 4 extends into the chamber 101 of the A-pillar main body 10 and coincides with the length L1 of the A-pillar inner panel 3. The length L2 of the sill beam 4 is greater than the length L1. In this way, after the front wheel impacts, the impact force is decomposed to the A-pillar main body 10 through the wheel arch side beam. At this time, the sill beam 4 can increase the strength of the A-pillar, enabling the A-pillar to have sufficient strength to resist, reducing the deformation of the occupant compartment, avoiding the occupation of the occupant compartment space due to insufficient strength of the A-pillar and endangering the personal safety of the occupants, and at the same time avoiding the rearward movement of the instrument panel skeleton and squeezing the living space of the front row occupants; avoiding deformation or tearing of the front door hinge mounting point due to insufficient strength, resulting in the door being torn open.

[0053] Based on the above embodiments, as Figure 7 、 Figure 8 and Figure 9 shown, a reinforcing beam 5 is provided in the sill beam 4, and a notch 51 is provided at one end of the reinforcing beam 5 close to the rear section of the wheel arch side beam 1.

[0054] Specifically, a reinforcing beam 5 is provided inside the sill beam 4, and the reinforcing beam 5 is fixed to the sill beam 4 by bolts. A notch 51 is provided at one end of the reinforcing beam 5 close to the rear section 1 of the wheelhouse side beam. It can also be understood that a notch 51 is provided at one end of the reinforcing beam 5 located at the A-pillar. The height of the notch 51 can reach half of the reinforcing beam 5, and the length of the notch 51 can exceed the midline of the A-pillar main body 10 (such as the Q line shown in Figure 7 ). Thus, the length of the notch 51 can be made longer. When the sill beam 4 is impacted, the reinforcing beam 5 can first be stressed at the end with the notch 51, and then gradually decompose the collision force to the end of the reinforcing beam 5 without the notch 51. It can be understood that the reinforcing beam 5 is stressed from a small area and gradually decomposed to a large area at the end of the reinforcing beam 5 without the notch 51, so that the force transmission path gradually increases from small to large, realizing the buffering of the impact force, effectively decomposing the impact force, reducing the impact force received by the occupant compartment, and reducing the deformation of the occupant compartment.

[0055] In some embodiments, as shown in Figure 9 and Figure 10 , the inside of the reinforcing beam 5 includes a plurality of cavities separated by at least one rib plate 52.

[0056] Specifically, exemplarily, a rib plate 52 is horizontally arranged at the middle position inside the reinforcing beam 5, and a plurality of rib plates 52 are vertically arranged. In this way, the inside of the reinforcing beam 5 is formed into a hollow shape, improving the sectional force of the reinforcing beam 5 and ensuring the strength of the collision force that the reinforcing beam 5 can withstand. If the reinforcing beam 5 is set as a solid one, when the reinforcing beam 5 is impacted, it will directly transmit the impact force to the occupant compartment, resulting in serious deformation of the occupant compartment. By setting the reinforcing beam 5 as a hollow shape, the reinforcing beam 5 can absorb energy within the A-pillar structure, better decompose the impact force, and avoid the problem of directly transmitting the impact force to the occupant compartment and causing serious deformation of the occupant compartment.

[0057] In some embodiments, as shown in Figure 7 , Figures 11 to 13 , a connecting plate 322 is provided on the inner panel 3 of the A-pillar. The connecting plate 322 is fixedly connected to the sill beam 4, and the length direction of the connecting plate 322 is parallel to the length direction of the sill beam 4.

[0058] Specifically, the cross-section of the connecting plate 322 (such as the cross-section formed by cutting the connecting plate 322 along the plane parallel to the a-plane in Figure 7 ) is Z-shaped. One end of the connecting plate 322 is fixed to the inner panel 3 of the A-pillar, and the other end is fixedly connected to the edge of the sill beam 4. Among them, the cross-section of the sill beam 4 (such as Figure 7The cross-section formed by cutting the sill beam 4 along the a plane) is in a shape of a capital letter 'J'. The convex part of the sill beam 4 fits against the outer panel 2 of the A-pillar, and the edge of the sill beam 4 is fixedly connected to the inner panel 3 of the A-pillar through a connecting plate 322. Since the connecting plate 322 is in a Z shape and cooperates with the edge of the sill beam 4, a first small cavity is formed. In this way, the A-pillar can have sufficient energy absorption effect and better strength, ensuring that the passenger compartment is not easily deformed.

[0059] In some embodiments, such as Figure 10 and Figure 11 shown, a partition rubber block 323 is provided on the inner panel 3 of the A-pillar, and the partition rubber block 323 is located above the sill beam 4.

[0060] Specifically, the inner panel 3 of the A-pillar and the outer panel 2 of the A-pillar form a second chamber 102. Since the vibration machine sound will generate different degrees of noise when propagating in the second chamber 102, a partition rubber block 323 is provided on the inner panel 3 of the A-pillar, and the partition rubber block 323 is located between the inner panel 3 of the A-pillar and the outer panel 2 of the A-pillar. There is a thermosensitive adhesive around the partition rubber block 323. The thermosensitive adhesive melts and fills to seal after painting and high-temperature baking, partitioning the chamber 101 formed by the inner panel 3 of the A-pillar and the outer panel 2 of the A-pillar, and can achieve a good sound insulation effect. In addition, since the sill beam 4 is located below the whole vehicle and is prone to getting wet, it is inevitable that dust impurities and water will enter during daily use of the vehicle. Setting the partition rubber block 323 above the sill beam 4 can prevent moisture, dust impurities from spreading upward to the A-pillar structure.

[0061] In some embodiments, such as Figure 8 、 Figure 9 and Figure 12 shown, a door hinge mounting plate 6 is further provided on the inner panel 3 of the A-pillar. The inner panel 3 of the A-pillar includes an upper inner panel segment 31 and a lower inner panel segment 32 connected up and down. The door hinge mounting plate 6 includes an upper mounting plate 61 and a lower mounting plate 62. The upper mounting plate 61 is provided at one end of the lower inner panel segment 32, and the lower mounting plate 62 is provided at the other end of the lower inner panel segment 32. The upper mounting plate 61 is arranged close to the upper inner panel segment 31;

[0062] One end of the lower mounting plate 62 is fixed to the lower inner panel segment 32 through a support plate 321, and the other end of the lower mounting plate 62 extends to the sill beam 4 and is fixedly connected to the sill beam 4.

[0063] Specifically, the inner panel 3 of the A-pillar includes an upper inner panel section 31 and a lower inner panel section 32 that are connected up and down, and the upper inner panel section 31 and the lower inner panel section 32 are welded together. The cross-sectional dimension of the upper inner panel section 31 is set to be smaller than that of the lower inner panel section 32. Since the upper inner panel section 31 and the lower inner panel section 32 are connected up and down, the lower inner panel section 32 can decompose more impact forces, thereby enabling the inner panel 3 of the A-pillar to have stronger strength. Since the cross-sectional dimension of the upper inner panel section 31 is smaller than that of the lower inner panel section 32, the door hinge mounting plate 6 is installed on the lower inner panel section 32 of the inner panel 3 of the A-pillar; in this way, the inner panel 3 of the A-pillar can have higher support strength and reduce the deformation of the A-pillar. The door hinge mounting plate 6 includes an upper mounting plate 61 and a lower mounting plate 62. The upper mounting plate 61 is arranged at one end of the lower inner panel section 32. It can be understood that the upper mounting plate 61 is arranged at one end close to the upper inner panel section 31 and is used for mounting the upper door hinge. And the length direction of the upper mounting plate 61 is in the same direction as the length direction of the sill beam 4. In this way, when the front wheel impacts and moves rearward to invade the A-pillar, the upper mounting plate 61 can increase the strength of the A-pillar. Further, the cross-section of the upper mounting plate 61 (such as Figure 7 the surface formed by cutting the upper mounting plate 61 along the plane parallel to the a-plane in Figure 7 is a U-shaped structure and is snap-fitted on the inner panel 3 of the A-pillar. In this way, while ensuring that the A-pillar has sufficient energy absorption, the strength of the A-pillar can also be enhanced. As shown in Figure 8 , the lower mounting plate 62 is arranged at the other end of the lower inner panel section 32; the specific installation is as follows: the top end of the lower mounting plate 62 is fixed to the lower inner panel section 32 through a support plate 321, and the bottom end of the lower mounting plate 62 extends to the sill beam 4 and is fixedly connected to the bottom of the sill beam 4. The bottom end of the lower mounting plate 62 is arranged parallel to the sill beam 4. In this way, the lower mounting plate 62 and the reinforcing beam 5 in the sill beam 4 can provide double-layer support, making the strength of the A-pillar structure stronger. Further, the lower mounting plate 62 can be L-shaped. The end of the L-shaped lower mounting plate with a protrusion extends to the sill beam 4 and is fixedly connected to the bottom of the sill beam 4, and the protrusion is arranged parallel to the sill beam 4. The protrusion can better decompose the impact force, enabling the lower mounting plate 62 and the reinforcing beam 5 in the sill beam 4 to provide double-layer support and making the strength of the A-pillar structure stronger. The end of the L-shaped lower mounting plate 62 without a protrusion is fixed to the lower inner panel section 32 through a support plate 321. Further, the side wall of the lower mounting plate 62 away from the sill beam 4 is attached to the outer panel 2 of the A-pillar, and a partition rubber block 323 is arranged between the lower mounting plate 62 and the inner panel 3 of the A-pillar. Further, the cross-section of the support plate 321 (such as Figure 7 the surface formed by cutting the support plate 321 along the plane parallel to the a-plane in

[0064] is a U-shaped structure. In this way, while ensuring that the A-pillar has sufficient energy absorption, the strength of the A-pillar can also be enhanced.

[0064] If the support plate 321 is a solid structure, it will cause the strength of the support plate 321 to be too high, decomposing all the impact force to the passenger compartment, resulting in the extrusion deformation of the passenger compartment and threatening the personal safety of the passengers. In this application, the support plate 321 is set as a non-solid structure with a C-shaped cross-section, which can solve this problem and avoid the extrusion deformation of the passenger compartment.

[0065] Furthermore, as Figure 12 shown, the second chamber 102 formed between the inner A-pillar panel 3 and the outer A-pillar panel 2 is isolated by the lower mounting plate 62, the partition rubber block 323 and the reinforcing beam 5 into a first small chamber 031, a second small chamber 032, a third small chamber 033 and a fourth small chamber 034 arranged in sequence from top to bottom. In this way, the four small chambers can ensure that the A-pillar structure has sufficient energy absorption. When subjected to a collision, it can absorb energy well, ensure the reduction of damage to the passenger compartment and ensure the safety of the passengers. Further, a serpentine structure is formed between the four small chambers, which can play a role in noise elimination, eliminating the noise of different degrees generated by the vibration noise propagating in the second chamber 102 and improving the user experience.

[0066] The above support plate 321 and connecting plate 322 can also be solid structures. When the support plate 321 and connecting plate 322 are solid structures, they can be made of foam aluminum plate material. Using foam aluminum plate can achieve sufficient energy absorption of the A-pillar while enhancing the strength of the A-pillar.

[0067] In some embodiments, referring to Figure 13 also includes a front bulkhead lower panel 7 and a torque box 8. The front bulkhead lower panel 7 and the torque box 8 are sequentially arranged up and down on the side of the inner A-pillar panel 3 away from the outer A-pillar panel 2; the connecting line of the front bulkhead lower panel 7 and the torque box 8 is on the same horizontal plane as one of the rib plates 52.

[0068] Specifically, the front bulkhead lower panel 7 is the bottom plate and the front bulkhead under the front row passenger compartment of the vehicle. The torque box 8 is an important connecting and force-transmitting member between the front engine bay longitudinal beam and the sill beam, the front floor and the front bulkhead lower cross member. The corners of the connection ends of the front bulkhead lower panel 7 and the torque box 8 with the inner A-pillar panel 3 are both set as arc structures. It can be understood that the lower left corner of the front bulkhead lower panel 7 is set as a rounded corner, and the upper left corner of the side of the torque box 8 connected to the front bulkhead lower panel 7 is set as a rounded corner. In this way, the distance between the front bulkhead lower panel 7 and the torque box 8 gradually increases to form a trumpet shape. After the front bulkhead lower panel 7 and the torque box 8 are connected to the inner A-pillar panel 3, slot holes are formed between the two rounded corners and the inner A-pillar panel 3. In this way, it can ensure that the A-pillar structure has sufficient energy absorption while enhancing the strength of the A-pillar and can effectively resist the side impact force.

[0069] Based on the same inventive concept, the second aspect of this application provides a vehicle, including an A-pillar structure according to any one of the above.

[0070] The A-pillar structure is provided on a vehicle. The bottom surface 021 of the rear section of the wheelhouse side beam of the A-pillar structure and the side surface 022 of the A-pillar main body are sequentially connected to form the second outer edge 02 of the A-pillar structure, and the bottom surface 021 of the rear section of the wheelhouse side beam and the side surface 022 of the A-pillar main body are smoothly transitioned. Along the direction from the rear section 1 of the wheelhouse side beam to the A-pillar main body 10, the distance between the first outer edge 01 and the second outer edge 02 gradually increases. In this way, the collision force decomposition can be effectively guided through the smoothly transitioned first outer edge and second outer edge, making the force transmission smoother, avoiding structural deformation and tearing caused by excessive local stress, and also avoiding the intrusion of the front wheel impact and rearward movement into the A-pillar, resulting in the occupation of the passenger survival space.

[0071] The sill beam 4 can increase the strength of the A-pillar, enabling the A-pillar to have sufficient strength to resist, reducing the deformation of the passenger compartment, avoiding the occupation of the passenger compartment space due to insufficient strength of the A-pillar, endangering the personal safety of the passengers, and at the same time avoiding the rearward movement of the instrument panel skeleton and squeezing the survival space of the front-row passengers; avoiding deformation or tearing of the front door hinge mounting point due to insufficient strength, resulting in the door being torn open.

[0072] The second chamber 102 formed between the inner A-pillar panel 3 and the outer A-pillar panel 2 is isolated into a first small chamber 031, a second small chamber 032, a third small chamber 033, and a fourth small chamber 034 arranged in sequence from top to bottom through the lower mounting plate 62, the partition rubber block 323, and the reinforcing beam 5. In this way, the four small chambers can ensure that the A-pillar structure has sufficient energy absorption. When subjected to a collision, it can absorb energy well, ensure the reduction of damage to the passenger compartment, and ensure the safety of the passengers. Further, a serpentine structure is formed between the four small chambers, which can play a role in sound absorption, eliminating the unequal degree of noise generated by the vibration machine sound propagating in the second chamber 102, and improving the user experience.
