Description

Technical Field

[0001] This application relates to the technical field of vehicle body structure, and specifically proposes a door sill beam sealing structure and a vehicle. Background Technology

[0002] In modern vehicle design, it is necessary to meet regulatory requirements for wading depth. Specifically, wading depth refers to the deepest water a vehicle can traverse, and vehicles generally use this as a reference point to define their wading line. The area below the wading line and including the engine compartment is called the wet zone. Conversely, the area above the wading line, where conductive wiring harnesses installed in the driver's cab, passenger compartment, and luggage compartment do not require special waterproofing, is called the dry zone. To improve the overall wading performance of the vehicle, critical electrical components should be located in the dry zone during electrical system design. Based on current vehicle wet / dry zone classification requirements, the interior of the A-pillar is considered part of the dry zone; therefore, water ingress into the A-pillar must be strictly prohibited.

[0003] However, in traditional vehicles, referencing Figure 1 The A-pillar typically covers the end of the door sill beam. However, since the end of the door sill beam is usually a grooved structure, it is difficult for the A-pillar to form an effective seal with the end of the door sill beam. When a vehicle drives over roads with a lot of standing water, water can easily enter from the bottom of the door sill beam into the gap between the end of the door sill beam and the A-pillar, and then spread into the interior of the A-pillar. This results in poor wading ability and compromises vehicle safety. Summary of the Invention

[0004] The purpose of this application is to solve at least some of the technical problems mentioned above, and this purpose is achieved through the following technical solutions:

[0005] In the first aspect, this application proposes a sill beam sealing structure, which includes a sill beam and an A-pillar. The sill beam passes through the A-pillar, and the A-pillar includes an inner A-pillar plate, an outer A-pillar plate, and a reinforcing member. The inner A-pillar plate and the outer A-pillar plate overlap at least with the side and top of the sill beam. A notch is provided at the position where the inner A-pillar plate and / or the outer A-pillar plate overlaps with the top of the sill beam, and the reinforcing member covers the notch.

[0006] In some embodiments, both the inner and outer A-pillar panels have protrusions and flanges, and the reinforcing member has a first plate, a second plate, and a third plate that intersect each other. The first plate overlaps with the top of the sill beam, the second plate overlaps with the protrusion of the inner or outer A-pillar panel, and the third plate overlaps with the flange of the inner or outer A-pillar panel.

[0007] In some embodiments, the reinforcement further has a fourth plate connected to the first plate, the fourth plate being sandwiched between the side of the sill beam and the inner or outer A-pillar plate.

[0008] In some embodiments, the inner panel of the A-pillar is provided with a notch, and the reinforcing member includes a first reinforcing member that covers the notch of the inner panel of the A-pillar. The first reinforcing member also has a fifth plate that is connected to the second plate. The protrusion of the inner panel of the A-pillar includes a first surface and a second surface that are at an angle to each other. The second plate overlaps with the first surface, and the fifth plate overlaps with the second surface.

[0009] In some embodiments, both the inner and outer panels of the A-pillar are provided with notches, and the reinforcing members include a first reinforcing member and a second reinforcing member. The first reinforcing member covers the notch in the inner panel of the A-pillar, and the second reinforcing member covers the notch in the outer panel of the A-pillar. The dimensions of the notch in the inner panel and the notch in the outer panel of the A-pillar are inconsistent along the vehicle height direction.

[0010] In some embodiments, the first reinforcing member and / or the second reinforcing member are provided with a boss, which is located within the notch and abuts against the edge of the notch.

[0011] In some embodiments, the reinforcing member is provided with a positioning hole, and a nut is welded to the reinforcing member at the position of the positioning hole, with the nut located at the position of the boss.

[0012] In some embodiments, structural adhesive is provided between the reinforcing member and the inner A-pillar panel at least along the edge of the reinforcing member, and a plurality of weld points are provided between the reinforcing member and the inner A-pillar panel along the extension path of the structural adhesive; and / or, structural adhesive is provided between the reinforcing member and the outer A-pillar panel at least along the edge of the reinforcing member, and a plurality of weld points are provided between the reinforcing member and the outer A-pillar panel along the extension path of the structural adhesive.

[0013] In some embodiments, a sealant is provided between the reinforcement and the sill beam along a portion of the edge of the reinforcement; a plurality of weld points are provided between the reinforcement and the sill beam along the extension path of the sealant.

[0014] Secondly, this application proposes a vehicle that includes the sill beam sealing structure of the first aspect.

[0015] The technical solution proposed in this application has at least the following technical effects:

[0016] In this application, the door sill beam extends through the A-pillar, and the A-pillar overlaps with the side and top of the door sill beam, resulting in a high degree of fit, good waterproofing, and improved wading capability. Furthermore, a notch is created at the overlap between the A-pillar and the top of the door sill beam to address sheet metal forming issues. Reinforcing components are also added to strengthen the notch, ensuring a stable overall structural connection, meeting vehicle body rigidity requirements, and further enhancing the vehicle's wading sealing performance.

[0031] To make the embodiments of this application clearer, they will be described below in conjunction with the accompanying drawings. It is to be understood that the content mentioned below is only a partial embodiment of this application, while the complete list of all embodiments is provided. Therefore, other embodiments obtained based on the following embodiments without any inventive effort all fall within the protection scope of this application.

[0032] It should be understood that the terminology used herein is for the purpose of describing specific embodiments only and is not intended to impose strict limitations on the technical solutions unless the context clearly indicates otherwise. For example, the use of "a," "an," and "the" to modify a feature does not preclude the possibility that the feature may be plural in other embodiments.

[0033] It should be understood that the terms "comprising," "including," and "having" are open-ended, indicating the presence of the stated features but not excluding the possibility of other features in the embodiment. Similarly, the use of terms such as "first," "second," etc., to describe multiple features only indicates the distinction between one feature and another, and such terms do not imply order or sequence unless explicitly stated in the context.

[0034] It should be understood that, unless the context clearly indicates otherwise, the terms "setup," "connection," and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integrated connection; they can refer to a direct connection or an indirect connection via a medium. Those skilled in the art will understand the specific meaning of these terms in this document based on the specific circumstances.

[0035] In addition, for ease of description, the text will use terms of spatial relative relationship to describe the position of one feature relative to another feature, such as "inner", "outer", "end", "side", "upper", "middle", "lower", "high", "low", "axial", "circumferential", "radial", "horizontal", "vertical", "first direction", "second direction", etc. It can be understood that the spatial relative relationship between two features should include other specific situations besides those shown in the accompanying drawings of the specification.

[0036] The background technology of this application will be further elaborated below.

[0037] In modern vehicle design, wading depth requirements must be met. Specifically, wading depth refers to the deepest water a vehicle can traverse, and vehicles typically use this as a reference point to define their wading line. The area below the wading line and including the engine compartment is called the wet zone. Conversely, the area above the wading line, where conductive wiring harnesses installed in the driver's cab, passenger compartment, and luggage compartment do not require special waterproofing, is called the dry zone. To improve the overall wading performance of the vehicle, critical electrical components should be located in the dry zone during electrical system design. Based on current vehicle wet / dry zone classification requirements, the interior of the A-pillar is considered part of the dry zone; therefore, water ingress into the A-pillar must be strictly prohibited.

[0038] However, in traditional vehicles, referencing Figure 1 The A-pillar typically covers the end of the sill beam 10'. However, since the end of the sill beam 10' is usually a grooved structure, it is difficult for the A-pillar to form an effective seal with the end of the sill beam 10'. When a vehicle drives over roads with a lot of standing water, water can easily enter from the bottom of the sill beam 10' into the gap between the end of the sill beam 10' and the A-pillar, and then spread into the interior of the A-pillar. This results in poor wading ability and compromises vehicle safety.

[0039] Specifically, Figure 1 The diagram shows the assembly relationship between the threshold beam 10' and the inner plate 210' of the A-pillar. The arrows in the diagram indicate the flow direction of water into the interior of the A-pillar.

[0040] Furthermore, if the sill beam is designed to penetrate the lower end of the A-pillar, thus avoiding the fit between the A-pillar and the sill beam profile ends, a further problem arises: the forming pressure at the point where the inner or outer A-pillar panel overlaps with the top of the sill beam is relatively high. Specifically, the inner A-pillar panel needs a protrusion at the aforementioned overlap to engage with the protrusion of the outer A-pillar panel to form the A-pillar cavity; the inner A-pillar panel also needs a flange connected to the protrusion at the aforementioned overlap to weld with the flange of the outer A-pillar panel; the inner A-pillar panel also needs a folded edge at the aforementioned overlap to overlap with the top of the sill beam. Moreover, the aforementioned protrusion, flange, and folded edge are all at angles to each other, not on the same plane, and form a relatively deep recess. When the inner A-pillar panel is integrally formed, forming at this point requires a large-angle bend, which easily reaches the forming limit of the sheet metal, causing the stress during forming to be transmitted to other parts of the inner A-pillar panel (mainly the outer side), resulting in cracking.

[0041] To address the aforementioned technical problems, this application provides a door sill beam sealing structure for vehicles, as detailed below.

[0042] The embodiments of this application will now be described with reference to the accompanying drawings.

[0043] Firstly, referring to Figure 2 According to an embodiment of the sill beam sealing structure of this application, it specifically includes a sill beam 10 and an A-pillar 20. The sill beam 10 passes through the A-pillar 20, and the A-pillar 20 includes an inner A-pillar plate 210, an outer A-pillar plate 220, and a reinforcing member 230. The inner A-pillar plate 210 and the outer A-pillar plate 220 are interlocked, and at least overlap with the side and top of the sill beam 10. A notch is provided at the position where the inner A-pillar plate 210 and / or the outer A-pillar plate 220 overlaps with the top of the sill beam 10, and the reinforcing member 230 covers the notch.

[0044] In this embodiment, the sill beam 10 extends through the lower end of the A-pillar 20, and the A-pillar 20 overlaps with the side and top of the sill beam 10, resulting in a high degree of fit, good waterproofing, and improved vehicle wading capability. Furthermore, a notch is provided at the overlap position between the A-pillar 20 and the top of the sill beam 10 to address sheet metal forming issues. A reinforcing member 230 is also provided to strengthen the notch, ensuring a stable overall structural connection, meeting vehicle body rigidity requirements, and further improving the vehicle's wading sealing performance.

[0045] First, the meaning of the above-mentioned "threshold beam 10 penetrates the lower end of column A 20" is as follows, referring to Figure 2The lower ends of the inner A-pillar panel 210 and the outer A-pillar panel 220 are bent in opposite directions, forming an inverted "Y"-shaped structure. The sill beam 10 passes through the space between the lower ends of the inner A-pillar panel 210 and the outer A-pillar panel 220, allowing the sill beam 10 to pass through the A-pillar 20. This means the A-pillar 20 no longer covers the end of the sill beam 10, eliminating the sealing difficulty.

[0046] Furthermore, in this embodiment, the inner A-pillar panel 210 and / or the outer A-pillar panel 220 have notches at the positions where they overlap with the top of the sill beam 10 to release stress and thus solve the sheet metal vehicle problem. Specifically, the above-mentioned "notches are provided at the positions where the inner A-pillar panel 210 and / or the outer A-pillar panel 220 overlap with the top of the sill beam 10" means that the notches can be provided only on the inner A-pillar panel 210, only on the outer A-pillar panel 220, or notches can be provided on both the inner A-pillar panel 210 and the outer A-pillar panel 220.

[0047] Taking the notch set on the inner plate 210 of the A-pillar as an example, since there is a notch at the joint between the inner plate 210 of the A-pillar and the sill beam 10, each edge of the inner plate 210 of the A-pillar can be folded at the notch position when it is formed. That is, the inner plate 210 of the A-pillar does not need to be formed with a deep recess structure, thus avoiding the problem of stress concentration.

[0048] Those skilled in the art will understand that when the notch is located on the outer panel 220 of the A-pillar, it also has the same advantages as described above.

[0049] Furthermore, in this embodiment, the reinforcing member 230 is a sheet material, and the sheet material is processed into a shape that can fill the gap, that is, the sheet material is processed into a structure with a recess. Those skilled in the art will understand that when only the inner A-pillar panel 210 has a gap, the reinforcing member 230 is set as one and covers the gap of the inner A-pillar panel 210; when only the outer A-pillar panel 220 has a gap, the reinforcing member 230 is set as one and covers the gap of the outer A-pillar panel 220; when both the inner A-pillar panel 210 and the outer A-pillar panel 220 have gaps, the reinforcing member 230 is set as two, one of which covers the gap of the inner A-pillar panel 210 and the other covers the gap of the outer A-pillar panel 220.

[0050] Furthermore, the reinforcement 230 provided in this embodiment has the following two advantages:

[0051] First, the reinforcing member 230 is placed at the gap, which means it makes up for the structural deficiency of the A-pillar 20 at the gap and strengthens the structure of the A-pillar 20.

[0052] Secondly, when manufacturing the reinforcing member 230, a slightly larger sheet material can be selected for molding. After molding, the edges of the reinforcing member 230 can be appropriately trimmed to meet the required size. Furthermore, when molding the recessed structure of the reinforcing member 230, if the internal stress is transmitted to the edge of the reinforcing member 230 and causes cracking at the edge, the edges of the reinforcing member 230 can be appropriately trimmed to remove the cracked part. Compared to the reinforcing member 230, the inner A-pillar panel 210 and outer A-pillar panel 220 are larger in volume. If the reinforcing member 230 is not used, and instead the inner A-pillar panel 210 and outer A-pillar panel 220 are directly recessed, when the internal stress is transmitted to the non-recessed structural parts of the inner A-pillar panel 210 and outer A-pillar panel 220 (i.e., the parts other than the recessed structure), causing cracks in the remaining parts, since the shape of the remaining parts of the inner A-pillar panel 210 and outer A-pillar panel 220 has been designed and determined, once cracks occur, they cannot be removed by cutting. Therefore, the inner A-pillar panel 210 and outer A-pillar panel 220 can only be scrapped.

[0053] Therefore, a notch is made in the inner panel 210 and outer panel 220 of the A-pillar, and a reinforcing member 230 is arranged to fill the notch. This reduces the risk of cracking of the A-pillar 20 during processing and ensures the processing quality of the recessed structure at the joint.

[0054] It should be noted that, theoretically, if a material with superior strength is selected, the A-pillar inner panel 210 and the A-pillar outer panel 220 can also be integrally molded, that is, edge cracking during processing can be avoided by strengthening the material strength. However, the total manufacturing cost will be higher than the solution in this embodiment. In summary, it is feasible to have a notch and a reinforcing member 230 in one of the A-pillar inner panel 210 and the A-pillar outer panel 220, while the other is integrally molded; or, both the A-pillar inner panel 210 and the A-pillar outer panel 220 have notches and reinforcing members 230.

[0055] It should be understood that, on the one hand, the inner A-pillar panel 210 and / or the outer A-pillar panel 220 can overlap with the side and top of the sill beam 10, as well as with the bottom of the sill beam 10; on the other hand, both ends of the inner A-pillar panel 210 and the outer A-pillar panel 220 in the vehicle's front-rear direction can overlap with the top of the sill beam 10, that is, notches can be opened and reinforcement members 230 can be provided at the front and rear parts of the inner A-pillar panel 210 and the outer A-pillar panel 220 (the positions where they overlap with the top of the sill beam 10).

[0056] In some embodiments, refer to Figures 2 to 4Both the inner A-pillar panel 210 and the outer A-pillar panel 220 have protrusions 201 and flanges 202. The reinforcing member 230 has a first plate 2301, a second plate 2302 and a third plate 2303 that intersect each other. The first plate 2301 overlaps with the top of the sill beam 10, the second plate 2302 overlaps with the protrusions 201 of the inner A-pillar panel 210 or the outer A-pillar panel 220, and the third plate 2303 overlaps with the flanges 202 of the inner A-pillar panel 210 or the outer A-pillar panel 220.

[0057] Furthermore, in the A-pillar 20, when the inner A-pillar panel 210 and the outer A-pillar panel 220 are fastened together, the protrusions 201 of the two form a cavity structure, and the flange 202 is used for the connection between the two.

[0058] In this embodiment, the three plates on the reinforcing member 230, which are at an angle to each other, overlap with the top of the sill beam 10 and the protrusion 201 and flange 202 of the A-pillar 20, respectively, resulting in a better fit, enhanced rigidity of the overall connection, and improved water-sealing performance.

[0059] In this embodiment, refer to Figure 3 and Figure 4 The reinforcing member 230 also has a fourth plate 2304 connected to the first plate 2301. The fourth plate 2304 is sandwiched between the side of the sill beam 10 and the inner plate 210 of the A-pillar or between the side of the sill beam 10 and the outer plate 220 of the A-pillar.

[0060] In this embodiment, the fourth plate 2304 is used to connect with the side of the sill beam 10 and the inner plate 210 or outer plate 220 of the A-pillar, further enhancing the rigidity of the overall connection and improving the water-sealing performance.

[0061] In some embodiments, refer to Figure 5 Structural adhesive 410 is provided between the reinforcing member 230 and the inner A-pillar panel 210 at least along the edge of the reinforcing member 230, and multiple weld points are provided between the reinforcing member 230 and the inner A-pillar panel 210 along the extension path of the structural adhesive 410; and / or, structural adhesive 410 is provided between the reinforcing member 230 and the outer A-pillar panel 220 at least along the edge of the reinforcing member 230, and multiple weld points are provided between the reinforcing member 230 and the outer A-pillar panel 220 along the extension path of the structural adhesive 410.

[0062] In this embodiment, the reinforcing member 230 can be pre-bonded to the inner A-pillar panel 210 or the outer A-pillar panel 220 through structural adhesive 410 and welding points to form a whole, which can be supplied and assembled together to improve production efficiency. In addition, the structural adhesive 410 is located at least on the edge of the reinforcing member 230, and the welding points on the coating path of the structural adhesive 410 are used to ensure a stable connection and also to provide waterproofing.

[0063] In some embodiments, refer to Figure 5A sealant 420 is provided along a portion of the edge of the reinforcing member 230 between the reinforcing member 230 and the sill beam 10, and multiple weld points are provided along the extension path of the sealant 420 between the reinforcing member 230 and the sill beam 10.

[0064] In this embodiment, a sealant 420 is provided between the reinforcing member 230 and the sill beam 10 for sealing treatment, and a weld point is provided for connection and reinforcement; specifically, the sealant 420 can be mainly located at the edge position of the surface of the first plate 2301 and the fourth plate 2304 facing the sill beam 10.

[0065] In some embodiments, refer to Figure 3 and Figure 6 The A-pillar inner panel 210 has a notch. The reinforcing member 230 includes a first reinforcing member 231, which covers the notch of the A-pillar inner panel 210. The first reinforcing member 231 also has a fifth plate 2305 connected to the second plate 2302. The protrusion 201 of the A-pillar inner panel 210 includes a first surface 2011 and a second surface 2012 that are at an angle to each other. The second plate 2302 overlaps with the first surface 2011, and the fifth plate 2305 overlaps with the second surface 2012.

[0066] In this embodiment, the first reinforcing member 231 has a fifth plate 2305, which overlaps with the second surface 2012 of the protrusion 201 of the A-pillar inner plate 210, enhancing the connection rigidity of the overall structure. In some embodiments, the fifth plate 2305 and the fourth plate 2304 are connected by a transition surface, as shown in the figure. Figure 5 The structural adhesive 410 between the first reinforcing member 231 and the inner A-pillar panel 210 includes a first structural adhesive 411, which extends sequentially along the edges of the fourth panel 2304, the fifth panel 2305, the second panel 2302, and the third panel 2303. Furthermore, referring to… Figure 5 The structural adhesive 410 between the first reinforcing member 231 and the inner A-pillar panel 210 may also include a second structural adhesive 412. The second structural adhesive 412 is specifically located between the fourth plate 2304 and the inner A-pillar panel 210, and may be distributed crosswise in the horizontal and vertical directions.

[0067] It should be noted that the edge of the second reinforcing member 232 is also provided with structural adhesive 410 and welding points to connect with the outer panel 220 of the A-pillar. The edges of the first plate 2301 and the fourth plate 2304 of the second reinforcing member 232 are also sealed with sealant 420 between them and the sill beam 10. (Refer to...) Figure 4 The fourth plate 2304 of the second reinforcing member 232 is relatively small, so the second structural adhesive 412 does not need to be provided on it.

[0068] In some embodiments, both the inner A-pillar panel 210 and the outer A-pillar panel 220 are provided with notches. The reinforcing member 230 includes a first reinforcing member 231 and a second reinforcing member 232. The first reinforcing member 231 covers the notch of the inner A-pillar panel 210, and the second reinforcing member 232 covers the notch of the outer A-pillar panel 220. The dimensions of the notch in the inner A-pillar panel 210 and the notch in the outer A-pillar panel 220 are inconsistent along the vehicle height direction.

[0069] Understandably, since the door sill beam 10 is not perfectly symmetrical on both sides along the left-right direction of the vehicle, and the inner A-pillar panel 210 and outer A-pillar panel 220 are also not perfectly symmetrical, the first reinforcing member 231 and the second reinforcing member 232 should be adapted accordingly. For example, compared to... Figure 3 and Figure 4 The first reinforcing member 231 has a fifth plate 2305, and the first plate 2301 and the third plate 2303 of the first reinforcing member 231 are wider, the second plate 2302 is narrower, and the fourth plate 2304 is larger; while the second reinforcing member 232 does not have a fifth plate 2305, and the first plate 2301 and the third plate 2303 of the second reinforcing member 232 are narrower, the second plate 2302 is larger, and the fourth plate 2304 is smaller. The above differences can be understood as special adaptive changes made to the structure of the sill beam 10 and the A-column 20.

[0070] In this embodiment, refer to Figure 2 Along the vehicle height direction, the notch height on the inner A-pillar panel 210 is h1, and the height of the first reinforcing member 231 is h2, meaning the highest welding height between the third plate 2303 of the first reinforcing member 231 and the flange 202 of the inner A-pillar panel 210 is h2; Figure 2 As shown, the height of the notch on the outer panel 220 of the A-pillar is h3, and the height of the second reinforcing member 232 is h4, meaning the highest welding height between the third plate 2303 of the second reinforcing member 232 and the flange 202 of the outer panel 220 of the A-pillar is h2. Figure 2As shown, the height of the notch in the inner A-pillar panel 210 is less than the height of the notch in the outer A-pillar panel 220, i.e., h1 < h3. Therefore, the height of the first reinforcing member 231, which matches the notch, is less than the height of the second reinforcing member 232, i.e., h2 < h4. It should be understood that the third plate 2303 of the first reinforcing member 231 also needs to be welded to the third plate 2303 of the second reinforcing member 232. If the third plate 2303 of the first reinforcing member 231 and the third plate 2303 of the second reinforcing member 232 have the same height, then at the highest point, a four-layer welding method will be formed, consisting of the flange 202 of the inner A-pillar panel 210, the third plate 2303 of the first reinforcing member 231, the third plate 2303 of the second reinforcing member 232, and the flange 202 of the outer A-pillar panel 220. This results in concentrated weld points, making deformation more likely and reducing welding quality. As described above, the highest points of the first reinforcing member 231 and the second reinforcing member 232 are offset, thus avoiding four-layer welding.

[0071] It should be noted that in some other embodiments not shown in the figures, the height of the notch in the inner A-pillar panel 210 may also be higher than the height of the notch in the outer A-pillar panel 220, so that the height of the first reinforcing member 231 is higher than the height of the second reinforcing member 232, which can also avoid the problem of four-layer welding and is also a feasible implementation method.

[0072] In some embodiments, refer to Figure 7 The first reinforcing member 231 and / or the second reinforcing member 232 are provided with a boss 2307, which is located within the notch and abuts against the edge of the notch. (Refer to...) Figure 8 In some embodiments, the reinforcing member 230 is provided with a positioning hole 2306, and a nut 2308 is welded to the reinforcing member 230 at the position of the positioning hole 2306. The nut 2308 is located at the position of the boss 2307.

[0073] Reference Figures 3 to 8In summary, in some embodiments, the notch on the inner A-pillar panel 210 is small. Therefore, the first surface 2011 of the protrusion 201 of the inner A-pillar panel 210 covers the second plate 2302 of the first reinforcing member 231. Specifically, the second plate 2302 of the first reinforcing member 231 does not have a boss 2307, but only a positioning hole 2306. The first reinforcing member 231 has a nut 2308 pre-welded at the position of the positioning hole 2306. The first surface 2011 of the inner A-pillar panel 210 has a clearance hole 203 communicating with the positioning hole 2306. The first surface 2011 of the inner A-pillar panel 210 also has a bolt 2309 pre-welded. In some embodiments, the notch of the outer A-pillar panel 220 is relatively large, and the second plate 2302 of the second reinforcing member 232 is exposed in greater extent. The second plate 2302 of the second reinforcing member 232 is provided with a boss 2307 that limits the edge of the notch on the outer A-pillar panel 220. The boss 2307 is provided with a positioning hole 2306, and a nut 2308 is pre-welded to the positioning hole 2306. A bolt 2309 is also pre-welded to the boss 2307.

[0074] It should be noted that, referring to Figure 9 The aforementioned nuts 2308 and bolts 2309 can be used to connect with the A-pillar support 30. The A-pillar support 30 has a slot, which clamps it to the outside of the flange 202 of the inner A-pillar plate 210 and the flange 202 of the outer A-pillar plate 220. Specifically, the positioning holes 2306 on the reinforcing member 230 can be used for tooling positioning during the forming stage of the reinforcing member 230. After forming, the positioning holes 2306 can be used to connect with the welded nuts 2308 to the A-pillar support 30. More specifically, after the A-pillar support 30 is placed, it can be locked with the pre-welded nuts 2308 using matching bolts, and then locked with the pre-welded bolts 2309 using matching nuts.

[0075] Here, refer to Figure 2 In some embodiments, the first plate 2301 of the reinforcing member 230 can also be locked to the top of the sill beam 10 by fasteners 102, thereby enhancing the connection rigidity of the structure and improving the sealing performance; furthermore, the fasteners 102 can be partially housed in the cavity 101 of the sill beam 10, thereby improving space utilization and avoiding interference between components.

[0076] Secondly, this application proposes a vehicle that includes the sill beam sealing structure of the first aspect.

[0077] Therefore, the vehicle of the second aspect possesses at least all the technical effects of the sill beam sealing structure of the first aspect, and its specific technical effects will not be elaborated here. Furthermore, the embodiments of this application only illustrate the structure of the vehicle of the second aspect related to the improvements of this application, but do not mean that it does not possess other structures. For example, the vehicle also includes door panels, B-pillars, etc., and other structures will not be described in detail here.

[0078] Optionally, the vehicle can be a new energy electric vehicle or a fuel vehicle.

[0080] In the first case, the term “and / or” located between the first subject and the second subject includes any of the following meanings: (1) only the first subject; (2) only the second subject; and (3) both the first subject and the second subject.

[0081] In the second case, the term "and / or" between the last two of three or more subjects means including at least any one of the subjects. For example, "first subject, second subject and / or third subject" has the same meaning as "first subject and / or second subject and / or third subject", specifically including the following combinations: (1) only the first subject; (2) only the second subject; (3) only the third subject; (4) the first subject and the second subject and no third subject; (5) the first subject and the third subject and no second subject; (6) the second subject and the third subject and no first subject; and (7) the first subject, the second subject and the third subject.
