Description

Technical Field

[0001] The utility model relates to the technical field of vehicle body structures, in particular to a side inner plate structure and a vehicle.

[0002] The utility model also relates to a vehicle provided with the side panel structure. Background Art

[0003] With the rapid development of the automobile industry and the increasing demand of consumers for automobile performance, the safety, lightweight and manufacturing cost control of vehicle body structure have become the focus of industry research. As an important part of the vehicle body, the design of the vehicle's side inner panel structure is not only related to the overall safety of the vehicle, but also directly affects the vehicle's manufacturing cost and lightweight goals.

[0004] In the existing side panel inner panel structure, the roof cross beam connecting plate is directly connected to the upper side beam inner plate to support the roof cross beam and the roof assembly. The structural setting will make the distance between the B-pillar inner plate supporting the upper side beam inner plate and the roof cross beam connecting plate longer. When the roof cross beam is subjected to a force in the height direction of the vehicle, the roof cross beam connecting plate will directly transfer the force to the upper side beam inner plate, and then the upper side beam inner plate will disperse the force to the B-pillar inner plate or other structures.

[0005] However, since the lower end of the upper side beam inner plate is connected to the B-pillar inner plate, the support effect is insufficient. When the upper side beam inner plate is subjected to force, it is easy to deform due to its limited strength, resulting in poor support performance of the top of the B-pillar inner plate on the upper side beam inner plate. At the same time, the force received by the roof cross beam connecting plate is difficult to effectively transmit to the B-pillar inner plate, resulting in poor force transmission performance at the top of the B-pillar inner plate. Utility Model Content

[0009] Furthermore, an upper lap joint is formed at the top of the B-pillar inner plate, and an upwardly protruding lap plate is provided at the top of the upper lap joint; the upper lap joint is overlapped at the bottom edge of the upper side beam inner plate, and the lap plate partially overlaps with the roof cross beam connecting plate.

[0013] Furthermore, a reinforcing plate is provided in the mold cavity, and the reinforcing plate is arranged along the length direction of the door sill beam, and at least a portion of the reinforcing plate extends into the mold cavity between the lower overlapping portion and the beam body.

[0014] Furthermore, a plurality of support plates are arranged at intervals on the reinforcing plate to support the beam body in the height direction of the vehicle, and / or a structural weakening hole is opened on the inner plate of the lower section.

[0015] Furthermore, it also includes a sill beam, and an A-pillar inner panel connected between the front end of the upper side beam inner panel and the front end of the sill beam; the A-pillar inner panel includes an upper side beam connecting section, a main section and a sill beam connecting section which are overlapped and connected up and down, the top of the upper side beam connecting section is connected to the upper side beam inner panel, and the bottom of the sill beam connecting section is connected to the sill beam.

[0016] Furthermore, a raised front cross beam connecting plate is provided on the side of the upper side beam connecting section facing the interior of the vehicle, and the front cross beam connecting plate is used to connect the front cross beam of the roof; and / or a torsion box is provided on the inner side of the front end of the sill beam, and the torsion box and the bottom of the sill beam connecting section at least partially overlap.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] The side panel inner plate structure described in the utility model is provided with an overlapped portion at the top of the B-pillar inner plate, and the overlapped portion, the inner wall of the upper side beam and the roof cross beam connecting plate are at least partially overlapped and connected, thereby improving the connection strength between the B-pillar inner plate, the upper side beam inner plate and the roof cross beam, so as to improve the supporting performance and force transmission performance at the top position of the side panel B-pillar inner plate, thereby improving the safety of the vehicle.

[0019] An upper overlap portion is formed at the top of the B-pillar inner plate, and an upwardly protruding overlap plate is formed on the upper overlap portion, and the overlap plate partially overlaps with the roof cross beam connecting plate. By arranging the overlap plate to overlap and connect with the upper side beam inner plate, the connection strength between the B-pillar inner plate and the upper side beam inner plate is improved. In addition, the overlap plate and the roof cross beam connecting plate overlap in the same area as the upper side beam inner plate, which improves the connection strength between the B-pillar inner plate, the upper side beam inner plate and the roof cross beam connecting plate, so as to ensure the support performance of the top position of the B-pillar inner plate.

[0020] The roof cross beam connecting plate is bent, including a top plate for connecting the roof cross beam and a side plate overlapping the inner wall of the upper side beam. By constructing the roof cross beam connecting plate in a bent shape, it is easy to connect with the top cross beam. When the top plate supports the roof cross beam, the pressure it receives can be transmitted to the side plate, and further transmitted to the inner plate of the upper side beam, thereby improving the supporting effect of the inner plate of the upper side beam on the roof cross beam.

[0021] The B-pillar inner panel includes an upper inner panel and a lower inner panel which are overlapped and connected. The bottom of the lower inner panel is formed with a widened lower overlap portion, which overlaps the door sill beam. By setting the B-pillar inner panel separately, it is easy to process and manufacture, and is conducive to the assembly operation of the B-pillar inner panel.

[0022] The sill beam includes a beam body with a "J"-shaped cross section, and the top and bottom of the lower overlapping portion are overlapped at the top and bottom flanges of the beam body respectively. By overlapping and connecting the flange of the sill beam with the B-pillar inner panel, the lower overlapping portion and the "J"-shaped beam body form a cavity structure. The cavity structure can improve the structural strength of the connection between the sill beam and the B-pillar inner panel, thereby ensuring the stability of the connection between the sill beam and the B-pillar inner panel.

[0023] A reinforcing plate is provided in the cavity of the sill beam and arranged along the length direction of the sill beam. The reinforcing plate can support the top and bottom walls of the sill beam to prevent the beam body from collapsing and deforming due to force, thereby improving the structural strength of the sill beam itself, and further improving the stability of the connection between the B-pillar inner plate and the sill beam.

[0024] The reinforcing plate is provided with multiple support plates at intervals to support the beam body in the height direction of the vehicle, thereby improving the structural strength of the reinforcing plate itself, preventing it from being crushed and deformed in the height direction of the vehicle, and improving the supporting effect of the reinforcing plate on the threshold beam.

[0025] The A-pillar inner panel includes an upper side beam connecting section and a main body section which are overlapped and connected to each other, thereby configuring the A-pillar inner panel to be a split structure, which is convenient for processing and manufacturing. In addition, the upper side beam connecting section, the main body section and the door sill beam connecting section are overlapped and connected to each other, thereby improving the structural strength of the A-pillar inner panel, so as to ensure that the side panel inner panel structure of this embodiment has good structural strength and force transmission performance.

In addition, the connection stability between the sill beam and the torsion box is improved, and the structural strength and buffering performance between the sill beam and the torsion box are improved.

[0027] Another object of the present invention is to provide a vehicle, on which the side wall inner panel structure as described above is provided.

[0048] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0049] Embodiment 1

[0050] The present embodiment relates to a side panel inner plate structure, which overall comprises an upper side beam inner plate 1, a B-pillar inner plate 2, and a roof cross beam connecting plate 3.

[0051] The top cover cross beam connecting plate 3 is overlapped on the inner side of the upper side beam inner plate 1 for connecting the top cover cross beam. The top of the B-pillar inner plate 2 is overlapped on the outer side of the upper side beam inner plate 1, and the overlapped parts of the B-pillar inner plate 2 and the top cover cross beam connecting plate 3 on the upper side beam inner plate 1 at least partially overlap.

[0052] It is understandable that when the roof cross beam is subjected to pressure from the top of the vehicle, part of the pressure can be transmitted to the B-pillar inner panel 2 via the roof cross beam connecting plate 3 and the upper side beam inner panel 1. At the same time, when the B-pillar inner panel 2 is subjected to impact force from the side of the vehicle, part of the impact force can be transmitted upward along the B-pillar inner panel 2 to the upper side beam inner panel 1, and finally transmitted and dispersed to other vehicle body structures, thereby preventing the vehicle body from being deformed due to external forces.

[0053] As described above, by providing an overlap portion at the top of the B-pillar inner panel 2, the overlap portion, the inner wall of the upper side beam and the roof cross beam connecting plate 3 are at least partially overlapped and connected, thereby improving the connection strength between the B-pillar inner panel 2 and the upper side beam inner panel 1 and the roof cross beam, so as to improve the supporting performance and force transmission performance at the top position of the side B-pillar inner panel 2, thereby improving the safety of the vehicle.

[0054] Based on the above overall introduction, specifically, the roof crossbeam of this embodiment is used to carry the roof assembly of the vehicle. At the same time, the B-pillar inner plate 2, the upper side beam inner plate 1 and the roof crossbeam connecting plate 3 can be connected by welding to improve the connection strength between the B-pillar inner plate 2 and the upper side beam inner plate 1, and between the upper side beam inner plate 1 and the roof crossbeam connecting plate 3, to ensure the support performance of the top position of the B-pillar inner plate 2. In addition, the B-pillar inner plate 2, the upper side beam inner plate 1, and the roof crossbeam connecting plate 3 can also be connected by riveting or screwing to reduce the stress concentration at the connection, thereby improving the structural strength of the connection.

[0055] In order to improve the connection strength between the B-pillar inner plate 2 and the upper side beam inner plate 1, an upper overlap portion 2011 is formed on the top of the B-pillar inner plate 2 of the present embodiment, and an upwardly protruding overlap plate 2012 is provided on the top of the upper overlap portion 2011. The upper overlap portion 2011 overlaps the bottom edge of the upper side beam inner plate 1, and the overlap plate 2012 partially overlaps the roof cross beam connecting plate 3. By arranging the overlap plate 2012 to overlap and connect with the upper side beam inner plate 1, the overlap area between the B-pillar inner plate 2 and the upper side beam inner plate 1 can be effectively increased, thereby improving the connection strength between the B-pillar inner plate 2 and the upper side beam inner plate 1. The partial overlap between the lap plate 2012 and the top cover cross beam connecting plate 3 can further increase the lap area between the B-pillar inner plate 2 and the upper side beam inner plate 1, and increase the overlapping area between the lap plate 2012 and the top cover cross beam connecting plate 3, so that the lap plate 2012 and the top cover cross beam connecting plate 3 overlap in the same area as the upper side beam inner plate 1, thereby improving the connection strength between the B-pillar inner plate 2, the upper side beam inner plate 1 and the top cover cross beam connecting plate 3, so as to ensure the supporting performance of the top position of the B-pillar inner plate 2.

[0056] In a specific implementation, a convex rib 2013 extending along the height direction of the vehicle is formed on the lap plate 2012. By setting the convex rib 2013, when the lap plate 2012 is connected to the upper side beam inner plate 1, the stress concentration on the lap plate 2012 can be reduced, thereby improving the structural strength of the lap plate 2012.

[0057] In order to improve the supporting effect of the top side beam inner plate 1 on the top cover beam, the top cover beam connecting plate 3 of the present embodiment is bent and includes a top plate 301 and a side plate 302 connected together, the middle and lower parts of the side plate 302 overlap with the lap plate 2012, and the top plate 301 is used to connect the top cover beam. By constructing the top cover beam connecting plate 3 into a bent shape, the structural strength of the top cover beam connecting plate 3 itself can be improved, and it is convenient to connect with the top beam. In addition, when the top plate 301 supports the top cover beam, the pressure it receives can be transmitted to the side plate 302, and further transmitted to the top side beam inner plate 1, thereby improving the supporting effect of the top side beam inner plate 1 on the top cover beam.

[0058] In a specific implementation, a reinforcement part 303 is formed between the top plate 301 and the side plate 302, and the reinforcement part 303 can support the top plate 301 to prevent the top plate 301 from bending downward due to force, causing the structure of the top cover cross beam connecting plate 3 to be damaged, thereby improving the overall structural strength of the top cover cross beam connecting plate 3. At the same time, an opening is provided on the reinforcement part 303, which can reduce the stress concentration on the top cover cross beam connecting plate 3 while reducing the weight of the top cover cross beam connecting plate 3 to ensure its structural strength.

[0059] In order to facilitate the processing and manufacturing of the B-pillar inner panel 2 and improve the structural strength of the B-pillar inner panel 2, the B-pillar inner panel 2 of this embodiment includes an upper section inner panel 201 and a lower section inner panel 202 which are overlapped and connected, and the bottom of the lower section inner panel 202 is formed with a widened lower overlap portion 2021. The side wall inner panel structure also includes a door sill beam 4, and the lower overlap portion 2021 overlaps the door sill beam 4. By setting the B-pillar inner panel 2 in a split manner, it can be easy to process and manufacture, and it is convenient for the assembly operation of the B-pillar inner panel 2. At the same time, the upper section inner panel 201 and the lower section inner panel 202 are overlapped and connected, and have good connection strength, thereby improving the overall structural strength of the B-pillar inner panel 2.

[0060] In order to improve the connection stability between the B-pillar inner panel 2 and the sill beam 4, the sill beam 4 of this embodiment includes a beam body with a "J"-shaped cross section, and the opening of the cavity formed by the beam body is arranged toward the vehicle exterior. The top and bottom of the lower overlap portion 2021 are overlapped at the flanges 401 of the top and bottom of the beam body respectively. By overlapping and connecting the flanges 401 of the sill beam 4 with the B-pillar inner panel 2, the lower overlap portion 2021 and the "J"-shaped beam body are formed to form a cavity structure, which can improve the structural strength of the connection between the sill beam 4 and the B-pillar inner panel 2, thereby ensuring the stability of the sill beam 4 connecting the B-pillar inner panel 2. In addition, when the B-pillar inner panel 2 is subjected to a force in the vehicle height direction, the force can be transmitted to the side of the sill beam 4, forming a torsion of the sill beam 4, and the "J"-shaped beam body of the sill beam 4 has a good torsion resistance, thereby improving the structural strength of the overall structure of the side inner panel.

[0061] In order to improve the structural strength of the sill beam 4 itself, and further improve the stability of the connection between the B-pillar inner plate 2 and the sill beam 4, a reinforcing plate 402 is provided in the mold cavity of this embodiment. The reinforcing plate 402 is arranged along the length direction of the sill beam 4, and at least part of the reinforcing plate 402 extends into the mold cavity between the lower overlap portion 2021 and the beam body. When the sill beam 4 is subjected to a force in the height direction of the vehicle, the reinforcing plate 402 can support the top wall and the bottom wall of the sill beam 4 to prevent the beam body from collapsing and deforming due to the force, thereby improving the structural strength of the sill beam 4 itself, and further improving the stability of the connection between the B-pillar inner plate 2 and the sill beam 4. In specific implementation, the part of the reinforcing plate 402 extending into the sill beam 4 is configured in a box shape, so that the reinforcing plate 402 fits the inner wall of the mold cavity of the sill beam 4, thereby improving the supporting effect of the reinforcing plate 402 on the sill beam 4.

[0062] On this basis, in order to further improve the structural strength of the sill beam 4 itself, in this embodiment, a plurality of support plates 403 are arranged at intervals on the reinforcing plate 402 to support the beam body, that is, the sill beam 4 in the height direction of the vehicle. Specifically, the support plates 403 are arranged in the cavity of the box-shaped reinforcing plate 402 to support the upper and lower ends of the reinforcing plate 402, thereby improving the structural strength of the reinforcing plate 402 itself, preventing it from being crushed and deformed in the height direction of the vehicle, and improving the supporting effect of the reinforcing plate 402 on the sill beam 4, thereby improving the structural strength of the sill beam 4 itself. In specific implementation, the support plates 403 are configured to be arranged in three on the reinforcing plate 402 to ensure the supporting effect on the reinforcing plate 402 and the sill beam 4. At the same time, a structural weakening hole 2022 is provided on the lower inner plate 202, and the structural weakening hole 2022 can serve as a weak part. When the B-pillar inner plate 2 is hit from the side of the vehicle, the B-pillar inner plate 2 at the structural weakening hole 2022 can be slightly bent toward the inside of the vehicle to play a buffering role.

[0063] In this embodiment, an A-pillar inner plate 5 connected between the front end of the upper side beam inner plate 1 and the front end of the threshold beam 4 is also included. The A-pillar inner plate 5 includes an upper side beam connecting section 501, a main section 502 and a threshold beam connecting section 503 which are connected by upper and lower overlaps. The top of the upper side beam connecting section 501 is connected to the upper side beam inner plate 1, and the bottom of the threshold beam connecting section 503 is connected to the threshold beam 4. By setting the A-pillar inner plate 5 as a split structure, it can be convenient for processing and manufacturing, and at the same time, it is beneficial to the assembly operation of the side enclosure inner plate structure. In addition, the upper side beam connecting section 501, the main section 502 and the threshold beam connecting section 503 are connected by overlapping, and the connection area is large and the connection is stable, thereby improving the structural strength of the A-pillar inner plate 5, so as to ensure that the side enclosure inner plate structure of this embodiment has good structural strength and force transmission performance.

[0064] In order to facilitate the installation and arrangement of the roof assembly, the upper side beam connecting section 501 of this embodiment is provided with a raised front cross beam connecting plate 504 on the side facing the interior of the vehicle. The front cross beam connecting plate 504 is used to connect the front cross beam of the roof to facilitate the overlapping installation of the front cross beam of the roof. At the same time, the front cross beam connecting plate 504 can transmit the force from the front cross beam of the roof to form a force transmission structure, thereby improving the force transmission performance of the upper part of the A-pillar inner plate 5. In addition, a torsion box 6 is provided on the inner side of the front end of the sill beam 4. The torsion box 6 and the bottom of the sill beam connecting section 503 at least partially overlap to improve the connection stability between the sill beam 4 and the torsion box 6. When the torsion box 6 is subjected to external force, the force can be transmitted to the sill beam 4, thereby improving the structural strength and buffering performance between the sill beam 4 and the torsion box 6.

[0065] In summary, the side panel inner panel structure of the present embodiment, by arranging a lap joint on the top of the B-pillar inner panel 2, overlaps and connects at least part of the lap joint, the inner wall of the upper side beam and the roof crossbeam connecting plate 3, thereby improving the connection strength between the B-pillar inner panel 2 and the upper side beam inner panel 1 and the roof crossbeam, so as to improve the supporting performance and force transmission performance at the top position of the side panel B-pillar inner panel 2, thereby improving the safety of the vehicle, and having good practicality.
