Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a vehicle body structure and a vehicle. Background Technology

[0002] Side impact sensors, also known as side collision sensors, are an important component of automotive safety systems, playing a crucial role, especially in modern intelligent vehicles.

[0003] The installation location of side impact sensors varies depending on the vehicle model, but they are typically installed under the B-pillar or inside the door using sensor mounting brackets. However, existing vehicle body structures have significant cumulative errors, which can easily lead to problems such as misaligned holes or obstructed holes at the side impact sensor mounting points. In some cases, the sensor mounting bracket may even push up other parts of the vehicle body, affecting the vehicle's accuracy. Utility Model Content

[0004] The main technical problem addressed by this application is to provide a vehicle body structure and vehicle that ensures smooth installation of side collision sensors, reduces installation difficulty, and facilitates sensor placement.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a vehicle body structure, including a B-pillar inner panel, a B-pillar reinforcing plate, and a sensor mounting bracket, wherein the B-pillar inner panel is provided with a first through hole; the B-pillar reinforcing plate is fixedly connected to one side of the B-pillar inner panel, and a mounting cavity is formed between the B-pillar reinforcing plate and the B-pillar inner panel; the sensor mounting bracket is fixed in the mounting cavity, and a portion of the sensor mounting bracket is exposed through the first through hole to form a mounting portion, the mounting portion being used to mount a sensor.

[0006] Preferably, the sensor mounting bracket includes a mounting plate and multiple connecting plates. One end of the connecting plate is connected to the edge of the mounting plate, and the other end of the connecting plate extends toward the B-pillar reinforcement plate and is connected to a flange.

[0009] Preferably, the distance between the edge of the mounting boss and the inner wall of the first through hole is 2mm-4mm.

[0010] Preferably, the inner plate of the B-pillar is further provided with a fixing part, which is located outside the first through hole and is fixedly connected to the mounting plate.

[0011] Preferably, the fixing part includes a plurality of second through holes circumferentially arranged around the first through hole.

[0012] Preferably, the B-pillar reinforcing plate includes a reinforcing plate and two side plates. The reinforcing plate is located on one side of the inner B-pillar panel. One end of each of the two side plates is connected to both sides of the reinforcing plate, and the other end of each side plate extends toward the inner B-pillar panel and is connected to a reinforcing plate flange. The reinforcing plate flange is fixedly connected to the inner B-pillar panel. The plurality of connecting plates include a first connecting plate, a second connecting plate, and a third connecting plate.

[0022] To make the objectives, technical solutions, and effects of this application clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] See Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of one embodiment of the vehicle body structure of this application. Figure 2 yes Figure 1 An exploded view is shown. The vehicle body structure 10 includes a B-pillar inner panel 11, a B-pillar reinforcing plate 12, and a sensor mounting bracket 13. Optionally, the vehicle body structure 10 also includes an inner sill 14 and a seat crossbeam 15. Along the width direction of the vehicle body, the B-pillar reinforcing plate 12 is fixedly connected to one side of the B-pillar inner panel 11, that is, the B-pillar reinforcing plate 12 is positioned on the outer side relative to the B-pillar inner panel 11. The inner sill 14 is connected below the B-pillar inner panel 11 and extends along the front-rear direction of the vehicle body. The B-pillar reinforcing plate 12, the B-pillar inner panel 11, and the inner sill 14 enclose each other, forming a mounting cavity 10a. A seat crossbeam 15 is provided on the inner side of the inner sill 14. The seat crossbeam 15 extends along the width direction of the vehicle body, and the end of the seat crossbeam 15 is fixedly connected to the inner side of the inner sill 14. A first through hole 111 is provided on the B-pillar inner panel 11, and the first through hole 111 is positioned in the front-rear direction of the vehicle body corresponding to the seat crossbeam 15. The sensor mounting bracket 13 is fixed inside the mounting cavity 10a, and part of the sensor mounting bracket 13 is exposed through the first through hole 111 to form a mounting part (not shown). The mounting part is used to mount the side collision sensor (not shown).

[0024] The vehicle body structure 10 of this application has a first through hole 111 on the inner panel 11 of the B-pillar, and a sensor mounting bracket 13 is provided between the inner panel 11 of the B-pillar and the reinforcing plate 12 of the B-pillar. The sensor mounting bracket 13 is provided corresponding to the first through hole 111, so that part of the sensor mounting bracket 13 can be exposed in the first through hole 111 to form a mounting part. The side collision sensor 20 can be directly installed on the mounting part, which can avoid the inner panel 11 of the B-pillar from increasing the installation error of the side collision sensor 20, thereby ensuring the smooth installation of the side collision sensor 20, reducing the installation difficulty, and facilitating the arrangement of the sensor.

[0025] Refer to Figure 3 , Figure 3 which is a schematic structural view of an embodiment of the sensor mounting bracket of the present application. In some embodiments, the sensor mounting bracket 13 includes a mounting plate 131 and a plurality of connecting plates 132. One end of the connecting plate 132 is connected to the edge of the mounting plate 131, and the other end of the connecting plate 132 extends towards the B-pillar reinforcement plate 12 and is connected with a flanging 133. The flanging 133 is fixedly connected to the B-pillar reinforcement plate 12, and the mounting part is located on the mounting plate 131. The mounting plate 131 is arranged on the side facing the B-pillar inner panel 11. The side of the mounting plate 131背离 the connecting plate 132 is used for mounting the side impact sensor 20. The connecting plate 132 is used to support the sensor mounting bracket 13 between the B-pillar reinforcement plate 12 and the B-pillar inner panel 11, which can enhance the strength of the B-pillar and ensure the mounting rigidity of the side impact sensor 20. The flanging 133 is used to weld the sensor mounting bracket 13 to the B-pillar reinforcement plate 12.

[0026] Specifically, continue to refer to Figure 2 and Figure 3 , the B-pillar reinforcement plate 12 includes a reinforcement plate 121 and two side plates 122. The reinforcement plate 121 is located outside the B-pillar inner panel 11 along the vehicle body width direction. One end of each of the two side plates 122 is connected to both sides of the reinforcement plate 121 respectively. The other end of the side plate 122 extends towards the B-pillar inner panel 11 and is connected with a reinforcement plate flanging 123. The reinforcement plate flanging 123 is fixedly connected to the B-pillar inner panel 11. The cross-section of the B-pillar reinforcement plate 12 perpendicular to the vertical direction is in a "C" shape.

[0027] It should be noted that there is an unclear expression "背离" in the original text, and I have translated it as "背离" as it is. You may need to check and correct it according to the actual situation. Also, the description of the cross-section shape of the B-pillar reinforcement plate in the original text may be inaccurate. I have translated it as described.Multiple connecting plates 132 include a first connecting plate 1321, a second connecting plate 1322, and a third connecting plate 1323. The flange 133 includes a first flange 1331, a second flange 1332, and a third flange 1333 that are respectively connected to the first connecting plate 1321, the second connecting plate 1322, and the third connecting plate 1323. The mounting plate 131 is quadrilateral in shape. The side of the quadrilateral closest to the side plate 122 is connected to the third connecting plate 1323. Two third flanges 1333 are connected to the end of the third connecting plate 1323 that is away from the mounting plate 131. The two opposite sides of the third flanges 1333 are welded to the reinforcing plate flange 123 of the B-pillar reinforcing plate 12 and the inner plate 11 of the B-pillar, respectively, to fix the B-pillar reinforcing plate 12, the inner plate 11 of the B-pillar, and the sensor mounting bracket 13 into one unit. Each of the other three sides of the mounting plate 131 is connected to a first connecting plate 1321. The first connecting plate 1321 extends towards the reinforcing plate 121 and is connected to a first flange 1331, which is welded to the reinforcing plate 121. One or more sides of the mounting plate 131 are also connected to a second connecting plate 1322. The second connecting plate 1322 extends towards the side plate 122 and is connected to a second flange 1332, which is welded to the inner side of the side plate. In this embodiment, by setting the first connecting plate 1321, the second connecting plate 1322, and the third connecting plate 1323, the sensor mounting bracket 13 is fixedly connected to various parts of the B-pillar reinforcing plate 12 from multiple directions, further increasing the rigidity of the sensor mounting bracket 13, ensuring the reliability of the side impact sensor 20 installation, and increasing the rigidity of the B-pillar structure.

[0028] Optionally, continue reading Figure 3 At least one first connecting plate 1321 and at least one second connecting plate 1322 partially overlap and are fixedly connected. Specifically, the first connecting plate 1321 and the second connecting plate 1322 located at the bottom edge of the mounting plate 131 partially overlap, and the two are welded at the overlapping portion. This arrangement further increases the rigidity of the connecting plate 132 and facilitates its formation.

[0029] Optionally, continue reading Figure 3The mounting part includes a mounting boss 134 protruding from the side opposite to the B-pillar reinforcement plate 12. The mounting boss 134 protrudes from the middle of the mounting plate 131 and passes through the first through hole 111. The mounting boss 134 is provided with a mounting hole (not shown). Specifically, the shape of the mounting boss 134 is the same as that of the first through hole 111. In this embodiment, both the mounting boss 134 and the first through hole 111 are oval and extend obliquely. The side impact sensor 20 is fixedly connected to the mounting boss 134 through the mounting hole. The mounting hole may specifically include a snap-fit ​​hole 1341 and a fixing hole 1342. The side impact sensor 20 is snapped into the snap-fit ​​hole 1341 by a snap fastener and locked into the fixing hole 1342 by a locking member. In this embodiment, by forming the mounting boss 134, the strength of the mounting plate 131 is further increased, ensuring the reliability of the sensor installation. On the other hand, since the mounting boss 134 protrudes to the side away from the B-pillar reinforcement plate 12 and protrudes to the inside of the B-pillar, that is, close to the mounting side of the side impact sensor 20, the installation difficulty of the side impact sensor 20 can be reduced, and the interference of the inner B-pillar plate 11 on the installation of the side impact sensor 20 can be reduced.

[0030] Further, see Figure 4 and Figure 5 , Figure 4 This is a front view of one embodiment of the vehicle body structure of this application. Figure 5 yes Figure 4 A cross-sectional view along the AA direction. The mounting boss 134 protrudes from the side of the B-pillar inner panel 11 away from the B-pillar reinforcing plate 12, that is, the mounting surface of the mounting boss 134 is located inside the B-pillar inner panel 11, which further reduces the difficulty of installing the side collision sensor and reduces the interference of the B-pillar inner panel 11 on the installation of the side collision sensor.

[0031] Optionally, please continue reading Figure 4 and Figure 5 The mounting boss 134 is clearance-fitted with the first through hole 111. The distance between the edge of the mounting boss 134 and the inner wall of the first through hole 111 is 2mm-4mm, for example, 3mm. By leaving a gap along the edge of the mounting boss 134, the installation error between the sensor mounting bracket 13 and the B-pillar can be avoided to prevent the hole from being blocked, thus ensuring smooth installation of the side impact sensor.

[0032] Optionally, the B-pillar inner panel 11 is also provided with a fixing part (not shown), which is located outside the first through hole 111 and is fixedly connected to the mounting plate 131. Specifically, the B-pillar inner panel 11 can be welded to the mounting plate 131, specifically by using carbon dioxide gas shielded welding, to fix the B-pillar inner panel 11, the B-pillar reinforcing plate 12, and the sensor mounting bracket 13 into an integrated structure. This ensures the reliability of the side impact sensor installation while improving the overall rigidity of the B-pillar and enhancing the overall crashworthiness of the vehicle body structure 10.

[0033] Optionally, please continue reading Figure 4 The fixing part includes multiple second through holes 112 surrounding the first through hole 111. Specifically, there are four second through holes 112, which are respectively arranged around the four sides of the first through hole 111. Solder can be placed in the second through holes 112 to fix the mounting plate 131 to the inner panel of the B-pillar without affecting the installation of the side collision sensor.

[0034] See Figure 6 , Figure 6 This is a partial structural schematic diagram of one embodiment of the vehicle described in this application. This application also provides a vehicle including the body structure 10 of any of the above embodiments and a side impact sensor 20, the side impact sensor 20 being fixedly connected to the mounting portion on the side facing away from the B-pillar reinforcement plate 12. The vehicle provided in this application includes various types of vehicles, such as electric vehicles, fuel vehicles, or sedans, SUVs (sports utility vehicles), etc.
