Description

Technical Field

[0001] The present application relates to the technical field of vehicle body structures, and specifically proposes a sill beam sealing structure and a vehicle. Background Art

[0002] In modern vehicle design, it is necessary to meet regulatory requirements for wading depth. Specifically, wading depth refers to the depth of the deepest water area that a vehicle can pass through, and the vehicle generally forms a wading line on itself based on this. Among them, the area below the wading line and the engine compartment is called the wet area. Relatively speaking, above the wading line, the conductive wiring harnesses installed in the cab, passenger compartment, luggage compartment and other parts do not need special waterproofing treatment, and this area is called the dry area. In order to improve the wading performance of the whole vehicle, the key electrical components of the whole vehicle should be arranged in the dry area when designing the electrical system. Based on the current vehicle dry and wet zone division requirements, the inside of the A-pillar of the vehicle belongs to the dry area, so it is necessary to strictly prohibit water from entering the inside of the A-pillar.

[0003] However, in conventional vehicles, Figure 1 The A-pillar usually wraps around the end of the sill beam, but since the end of the sill beam is usually a groove structure, it is difficult for the A-pillar to form an effective seal with the end of the sill beam. When a vehicle passes through a road with a lot of water, the water easily enters from the bottom of the sill beam into the gap between the end of the sill beam and the A-pillar, and then spreads to the inside of the A-pillar, resulting in poor wading ability and difficulty in ensuring the safety of the vehicle.

[0036] The background technology of this application is further described below.

[0037] In modern vehicle design, the requirements for wading depth need to be met. Specifically, wading depth refers to the depth of the deepest water area that a vehicle can pass through, and the vehicle generally forms a wading line on itself based on this. Among them, the area below the wading line and the engine compartment is called the wet area. Relatively speaking, above the wading line, the conductive wiring harnesses installed in the cab, passenger compartment, luggage compartment and other parts do not need special waterproofing treatment, and this area is called the dry area. In order to improve the wading performance of the whole vehicle, the key electrical components of the whole vehicle should be arranged in the dry area when designing the electrical system. Based on the current vehicle dry and wet zone division requirements, the inside of the A-pillar of the vehicle belongs to the dry area, so it is necessary to strictly prohibit water from entering the inside of the A-pillar.

[0038] However, in conventional vehicles, Figure 1 The A-pillar generally wraps around the end of the sill beam 10', but since the end of the sill beam 10' is generally a groove structure, it is difficult for the A-pillar to form an effective seal with the end of the sill beam 10'. When a vehicle passes through a road with a lot of water, the water easily enters 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 spreads to the inside of the A-pillar, resulting in poor wading ability and difficulty in ensuring the safety of the vehicle.

[0039] Specifically, Figure 1 FIG. 2 shows the assembly relationship between the sill beam 10 ′ and the A-pillar inner plate 210 ′, and the arrow in the figure indicates the flow direction of water entering the interior of the A-pillar.

[0040] In addition, if the threshold beam is set to pass through the lower end of the A-pillar, that is, avoiding the matching mode of the profile end faces of the A-pillar and the threshold beam, there will be a further problem that the A-pillar inner plate or the A-pillar outer plate has a high molding pressure at the part where it overlaps with the top of the threshold beam. Specifically, the A-pillar inner plate needs to have a protrusion at the above-mentioned overlap to snap with the protrusion of the A-pillar outer plate to form the A-pillar cavity; the A-pillar inner plate also has a flange connected to the protrusion at the above-mentioned overlap to be welded with the flange of the A-pillar outer plate; the A-pillar inner plate also needs to have a folded edge at the above-mentioned overlap to overlap with the top of the threshold beam, and the above-mentioned protrusion, flange and folded edge are angled with each other, are not in the same plane and form a deeper pit. In the case of one-piece molding of the A-pillar inner plate, the molding at this place requires a large angle bend, which is easy to reach the molding limit of the sheet metal, so that the stress during molding is transmitted to other parts of the A-pillar inner plate (mainly on the outside) and causes cracks.

[0041] In order to solve the above technical problems, the present application provides a sill beam sealing structure applied to a vehicle, as follows.

[0042] The embodiments of the present application are described below in conjunction with the accompanying drawings.

[0043] First, refer to Figure 2 According to the embodiment of the sill beam sealing structure of the present 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 A-pillar inner plate 210, an A-pillar outer plate 220 and a reinforcement 230. Among them, the A-pillar inner plate 210 and the A-pillar outer plate 220 are interlocked, and the A-pillar inner plate 210 and the A-pillar outer plate 220 overlap at least the side and the top of the sill beam 10, and a gap is provided at the position where the A-pillar inner plate 210 and / or the A-pillar outer plate 220 overlap the top of the sill beam 10, and the reinforcement 230 covers the gap.

[0044] In this embodiment, the threshold beam 10 passes through the lower end of the A-pillar 20, and the A-pillar 20 overlaps the side and top of the threshold beam 10, with high fit and good waterproof effect, thereby improving the wading ability of the vehicle. In addition, a gap is provided at the overlap position of the A-pillar 20 and the top of the threshold beam 10 to solve the sheet metal forming problem, and a reinforcement member 230 is provided to strengthen the strength of the gap, thereby ensuring the overall structural connection is stable, so that the vehicle body rigidity meets the requirements, and the vehicle wading sealing performance can also be improved.

[0045] First, the meaning of the above-mentioned “the threshold beam 10 passes through the lower end of the A-pillar 20” is, with reference to Figure 2The lower ends of the A-pillar inner panel 210 and the A-pillar outer panel 220 are bent away from each other to form an inverted "Y"-shaped structure. The sill beam 10 passes through the space between the lower ends of the A-pillar inner panel 210 and the lower ends of the A-pillar outer panel 220, so that the sill beam 10 passes through the A-pillar 20, that is, the A-pillar 20 no longer wraps the end of the profile of the sill beam 10, eliminating the problem of sealing difficulty.

[0046] Furthermore, in this embodiment, the A-pillar inner panel 210 and / or the A-pillar outer panel 220 are provided with a notch at the position where they overlap with the top of the sill beam 10 to release stress, thereby solving the problem of sheet metal vehicle models. Specifically, the above-mentioned "a notch is provided at the position where the A-pillar inner panel 210 and / or the A-pillar outer panel 220 overlaps with the top of the sill beam 10" means that the notch can be provided only on the A-pillar inner panel 210, or only on the A-pillar outer panel 220, or both the A-pillar inner panel 210 and the A-pillar outer panel 220 are provided with a notch.

[0047] Taking the notch set on the A-pillar inner panel 210 as an example, since the notch is set at the overlap between the A-pillar inner panel 210 and the door sill beam 10, when the A-pillar inner panel 210 is formed, each folding edge can be folded at the position of the notch, that is, the A-pillar inner panel 210 does not need to form a deeper pit structure, thereby avoiding the problem of stress concentration.

[0048] Those skilled in the art can understand that when the notch is provided on the A-pillar outer panel 220 , the same advantages as above are also achieved.

[0049] Furthermore, the reinforcement 230 in this embodiment is a sheet material, and the sheet material is processed into a shape that can make up for the position of the notch, that is, the sheet material is processed into a structure with a pit. Those skilled in the art can understand that when only the A-pillar inner plate 210 is provided with a notch, the reinforcement 230 is provided as one and covers the notch of the A-pillar inner plate 210; when only the A-pillar outer plate 220 is provided with a notch, the reinforcement 230 is provided as one and covers the notch of the A-pillar outer plate 220; when both the A-pillar inner plate 210 and the A-pillar outer plate 220 are provided with notches, the reinforcement 230 is provided as two, one of which covers the notch of the A-pillar inner plate 210, and the other covers the notch of the A-pillar outer plate 220.

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

[0051] First, the reinforcement member 230 is disposed at the notch, that is, to make up for the structural defect of the A-pillar 20 at the notch and to reinforce the structure of the A-pillar 20 .

[0052] Secondly, when manufacturing the reinforcement 230, a slightly larger plate material can be selected for molding, and after molding, the edge of the reinforcement 230 can be appropriately trimmed to meet the required size. When the pit structure of the reinforcement 230 is molded, if the internal stress is transmitted to the edge of the reinforcement 230 and causes the edge of the reinforcement 230 to crack, the edge of the reinforcement 230 can be appropriately trimmed to remove the cracked portion. The A-pillar inner panel 210 and the A-pillar outer panel 220 are larger in size than the reinforcement 230. If the reinforcement 230 is not used, but the A-pillar inner panel 210 and the A-pillar outer panel 220 are directly dented, when the internal stress is transmitted to the non-dented structural part (i.e., the rest of the part except the pit structure) on the A-pillar inner panel 210 and the A-pillar outer panel 220 and causes the rest of the part to crack, since the shapes of the rest of the parts on the A-pillar inner panel 210 and the A-pillar outer panel 220 have been designed and determined, once cracks occur, they cannot be removed by cutting, and therefore the A-pillar inner panel 210 and the A-pillar outer panel 220 can only be scrapped.

[0053] Therefore, a gap is opened in the A-pillar inner panel 210 and the A-pillar outer panel 220, and a reinforcement 230 is arranged to fill the gap. On the one hand, the risk of cracking of the A-pillar 20 during processing is reduced, and on the other hand, the processing quality of the pit structure processed at the overlap is ensured.

[0054] It should be noted that, in theory, if a material with better strength is selected, the A-pillar inner panel 210 and the A-pillar outer panel 220 can also be formed in one piece, that is, by strengthening the material strength to avoid edge cracking during processing, but the total manufacturing cost will be higher than the solution of this embodiment. In short, one of the A-pillar inner panel 210 and the A-pillar outer panel 220 has a notch and is provided with a reinforcement 230, and the other is formed in one piece; or both the A-pillar inner panel 210 and the A-pillar outer panel 220 have a notch and are provided with a reinforcement 230, which are both feasible implementation methods.

[0055] It should be understood that, on the one hand, the A-pillar inner panel 210 and / or the A-pillar outer panel 220 can overlap with the side and top of the rocker beam 10 as well as the bottom of the rocker beam 10; on the other hand, both ends of the A-pillar inner panel 210 and the A-pillar outer panel 220 along the front-rear direction of the vehicle can overlap with the top of the rocker beam 10, that is, the front and rear parts of the A-pillar inner panel 210 and the A-pillar outer panel 220 (the positions overlapping with the top of the rocker beam 10) can be notched and reinforced with a reinforcement 230.

[0056] In some embodiments, reference Figures 2 to 4The A-pillar inner panel 210 and the A-pillar outer panel 220 both have a raised portion 201 and a flange 202. The reinforcement 230 has a first plate body 2301, a second plate body 2302 and a third plate body 2303 that intersect in pairs. The first plate body 2301 overlaps with the top of the door sill beam 10, the second plate body 2302 overlaps with the raised portion 201 of the A-pillar inner panel 210 or the A-pillar outer panel 220, and the third plate body 2303 overlaps with the flange 202 of the A-pillar inner panel 210 or the A-pillar outer panel 220.

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

[0058] In this embodiment, the three plates on the reinforcement 230 that are angled with each other overlap with the top of the door sill beam 10 and the raised portion 201 and the flange 202 of the A-pillar 20 respectively, which has a better fit, enhances the rigidity of the overall connection, and improves the water-sealing performance.

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

[0060] In this embodiment, the fourth plate body 2304 is used to be connected to the side of the door sill beam 10 and the A-pillar inner plate 210 or the A-pillar outer plate 220 to further enhance the rigidity of the overall connection and improve the water-sealing performance.

[0061] In some embodiments, reference Figure 5 A structural adhesive 410 is provided between the reinforcement 230 and the A-pillar inner panel 210 at least along the edge of the reinforcement 230, and a plurality of welding points are provided between the reinforcement 230 and the A-pillar inner panel 210 along the extension path of the structural adhesive 410; and / or, a structural adhesive 410 is provided between the reinforcement 230 and the A-pillar outer panel 220 at least along the edge of the reinforcement 230, and a plurality of welding points are provided between the reinforcement 230 and the A-pillar outer panel 220 along the extension path of the structural adhesive 410.

[0062] In this embodiment, the reinforcement 230 can be pre-combined with the A-pillar inner panel 210 or the A-pillar outer panel 220 through the 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 at least located at the edge of the reinforcement 230, and cooperates with the welding points on the coating path of the structural adhesive 410 to ensure a stable connection and to play a waterproof role.

[0063] In some embodiments, reference Figure 5A sealant 420 is provided between the reinforcement 230 and the threshold beam 10 along a portion of the edge of the reinforcement 230 , and a plurality of welding points are provided between the reinforcement 230 and the threshold beam 10 along an extension path of the sealant 420 .

[0064] In this embodiment, a sealant 420 is provided between the reinforcement 230 and the threshold beam 10 for sealing, and welding points are provided for connection reinforcement; specifically, the sealant 420 can be mainly located at the edge of the surface of the first plate 2301 and the fourth plate 2304 facing the threshold beam 10.

[0065] In some embodiments, reference Figure 3 and Figure 6 The A-pillar inner plate 210 is provided with a notch, and the reinforcement 230 includes a first reinforcement 231, the first reinforcement 231 covers the notch of the A-pillar inner plate 210, and the first reinforcement 231 also has a fifth plate 2305 connected to the second plate 2302. The raised portion 201 of the A-pillar inner plate 210 includes a first surface 2011 and a second surface 2012 that are angled with each other, the second plate 2302 overlaps the first surface 2011, and the fifth plate 2305 overlaps the second surface 2012.

[0066] In this embodiment, the first reinforcement member 231 has a fifth plate 2305, and the fifth plate 2305 overlaps with the second surface 2012 of the raised portion 201 of the A-pillar inner plate 210 to enhance the connection stiffness of the overall structure. In some embodiments, the fifth plate 2305 is connected to the fourth plate 2304 through a transition surface. Figure 5 The structural adhesive 410 between the first reinforcement 231 and the A-pillar inner plate 210 includes a first structural adhesive 411, and the first structural adhesive 411 can extend along the edge of the fourth plate 2304, the edge of the fifth plate 2305, the edge of the second plate 2302, and the edge of the third plate 2303 in sequence. Figure 5 The structural adhesive 410 between the first reinforcement 231 and the A-pillar inner panel 210 may further include a second structural adhesive 412 . The second structural adhesive 412 is specifically located between the fourth plate 2304 and the A-pillar inner panel 210 , and may be cross-distributed along the horizontal and vertical directions.

[0067] It should be noted that the edge of the second reinforcement 232 is also provided with structural adhesive 410 and welding points to be combined with the A-pillar outer panel 220, and the edges of the first plate 2301 and the fourth plate 2304 of the second reinforcement 232 and the door sill beam 10 are also sealed with sealant 420, see Figure 4 The fourth plate 2304 of the second reinforcement member 232 is relatively small, so the second structural adhesive 412 may not be provided thereon.

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

[0069] It is understandable that since the two sides of the sill beam 10 along the left-right direction of the vehicle are not completely symmetrical, and the A-pillar inner panel 210 and the A-pillar outer panel 220 are not completely symmetrical, the first reinforcement member 231 and the second reinforcement member 232 should be adaptively arranged. Figure 3 and Figure 4 The first reinforcement 231 has a fifth plate 2305, and the first plate 2301 and the third plate 2303 of the first reinforcement 231 are wider, the second plate 2302 is narrower, and the fourth plate 2304 is larger; while the second reinforcement 232 is not provided with the fifth plate 2305, and the first plate 2301 and the third plate 2303 of the second reinforcement 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 door sill beam 10 and the A-pillar 20.

[0070] In this embodiment, refer to Figure 2 , along the vehicle height direction, the height of the notch on the A-pillar inner plate 210 is h1, and the height of the first reinforcement 231 is h2, that is, the highest welding height between the third plate 2303 of the first reinforcement 231 and the flange 202 of the A-pillar inner plate 210 is h2; Figure 2 As shown, the height of the notch on the A-pillar outer panel 220 is h3, and the height of the second reinforcement 232 is h4, that is, the highest welding height between the third plate 2303 of the second reinforcement 232 and the flange 202 of the A-pillar outer panel 220 is h2. Figure 2As shown, the height of the notch of the A-pillar inner plate 210 is smaller than the height of the notch of the A-pillar outer plate 220, that is, h1<h3, so that the height of the first reinforcement 231 matched with the notch is smaller than the height of the second reinforcement 232, that is, h2<h4. It should be understood that the third plate 2303 of the first reinforcement 231 also needs to be welded with the third plate 2303 of the second reinforcement 232. If the third plate 2303 of the first reinforcement 231 is consistent in height with the third plate 2303 of the second reinforcement 232, then at the highest point, a four-layer welding method will be formed, including the flange 202 of the A-pillar inner plate 210, the third plate 2303 of the first reinforcement 231, the third plate 2303 of the second reinforcement 232, and the flange 202 of the A-pillar outer plate 220, with concentrated welding points, easy deformation, and reduced welding quality. In the above-mentioned configuration, the highest points of the first reinforcement member 231 and the second reinforcement member 232 are offset, thereby avoiding four-layer welding.

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

[0072] In some embodiments, reference Figure 7 The first reinforcement member 231 and / or the second reinforcement member 232 is provided with a boss 2307, and the boss 2307 is located in the notch and abuts against the edge of the notch. Figure 8 In some embodiments, a positioning hole 2306 is provided on the reinforcement member 230 , and a nut 2308 is welded on the reinforcement member 230 at the position of the positioning hole 2306 , and 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 A-pillar inner plate 210 is relatively small, so the first surface 2011 of the raised portion 201 of the A-pillar inner plate 210 covers the second plate body 2302 of the first reinforcement 231. Specifically, no boss 2307 is provided on the second plate body 2302 of the first reinforcement 231, and only a positioning hole 2306 is provided. The first reinforcement 231 is pre-welded with a nut 2308 at the position of the positioning hole 2306, and the first surface 2011 of the A-pillar inner plate 210 is provided with an avoidance hole 203 connected to the positioning hole 2306. The first surface 2011 of the A-pillar inner plate 210 is also pre-welded with a bolt 2309. In some embodiments, the notch of the A-pillar outer panel 220 is larger, and a larger portion of the second plate body 2302 of the second reinforcement 232 is exposed. A boss 2307 is provided on the second plate body 2302 of the second reinforcement 232 to limit the edge of the notch on the A-pillar outer panel 220. A positioning hole 2306 is provided on the boss 2307, and a nut 2308 is pre-welded at the positioning hole 2306. A bolt 2309 is also pre-welded on the boss 2307.

[0074] It should be noted that, refer to Fig. 9 The above-mentioned nuts 2308 and bolts 2309 can be used to connect with the A-pillar support 30. The A-pillar support 30 has a slit, and the A-pillar support 30 is clamped on the flange 202 of the A-pillar inner plate 210 and the outer side of the flange 202 of the A-pillar outer plate 220 through the slit. Specifically, the positioning hole 2306 on the reinforcement 230 can be used for tooling positioning and molding during the molding stage of the reinforcement 230. After molding, the positioning hole 2306 can be connected to the A-pillar support 30 with the welded nut 2308. More specifically, after the A-pillar support 30 is placed, the matching bolts can be used to lock the pre-welded nuts 2308, and the matching nuts can be used to lock the pre-welded bolts 2309.

[0075] Here, refer to Figure 2 In some embodiments, the first plate 2301 of the reinforcement 230 can also be locked with the top of the threshold beam 10 through the fastener 102 to enhance the connection rigidity of the structure and improve the sealing performance; further, the fastener 102 can be partially received in the cavity 101 of the threshold beam 10 to improve space utilization and avoid interference between components.
