Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of vehicles, and in particular, to a sill assembly and a vehicle. Background Art

[0002] The sill assembly is one of the important structural components of vehicle equipment, and the sill assembly can ensure the integrity and structural strength of the vehicle body. The higher the strength of the sill assembly, the more beneficial it is to improve the side impact resistance performance of the vehicle. The sill assembly can be connected to the front apron, front floor, rear floor, etc. of the vehicle body. The sill assembly may include an outer panel and an inner panel.

[0003] However, the sill assembly in the above related technologies has a relatively large weight and a low dimensional accuracy, which affects the production efficiency and manufacturing cost of the sill assembly and the vehicle. Utility Model Content

[0004] In view of this, the embodiments of the present application provide a sill assembly and a vehicle, which are used to solve the technical problems that the sill assembly in the above related technologies has a relatively large weight and a low dimensional accuracy, which affects the production efficiency and manufacturing cost of the sill assembly and the vehicle.

[0005] In order to achieve the above object, the technical solution of the embodiments of the present application is realized as follows:

[0006] The embodiments of the present application provide a sill assembly, which includes:

[0007] An outer sill mechanism, including an outer sill front section, an outer sill middle section, and an outer sill rear section that are connected to each other;

[0008] An inner sill mechanism, which is connected to the outer sill front section, the outer sill middle section, and the outer sill rear section, and together encloses a first cavity;

[0009] A strengthening mechanism, which is arranged in the first cavity and is connected to the inner wall of the inner sill mechanism facing the first cavity;

[0010] Wherein, the density of the strengthening mechanism is less than the density of the outer sill mechanism and the inner sill mechanism.

[0011] In the threshold assembly provided by the embodiments of the present application, compared with setting the outer threshold mechanism as a whole structure, the outer threshold mechanism includes a front section of the outer threshold, a middle section of the outer threshold, and a rear section of the outer threshold that are connected to each other. During the processing and manufacturing process, it is easier to maintain dimensional accuracy and reduce dimensional tolerances. Setting the outer threshold mechanism as a three-section structure can facilitate adjustment and calibration, and when the dimensional tolerances of one or two of the sections are large, it can be adjusted separately, reducing material waste and adjustment time. Moreover, by setting the outer threshold mechanism as the front section of the outer threshold, the middle section of the outer threshold, and the rear section of the outer threshold, since the length of each section is relatively shorter than the whole, the probability of problems such as deformation during the processing of each section is relatively small, and the deformation amount is also relatively small, which is convenient for structural adjustment and improves the production efficiency of the threshold assembly.

[0012] By providing a strengthening structure in the first cavity formed by the outer threshold mechanism and the inner threshold mechanism, the structural strength of the threshold assembly can be further improved, thereby enhancing the impact resistance of the threshold assembly.

[0013] By making the strengthening mechanism supported by a material with a density smaller than that of the inner threshold mechanism and the outer threshold mechanism, the structural strength of the threshold assembly can be ensured, and the weight of the threshold assembly can be reduced, which helps to achieve the lightweight design of the threshold assembly and the vehicle.

The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0078] The embodiments of the present application provide a sill assembly and a vehicle, which can simplify the manufacturing process of the sill assembly, improve the manufacturing precision and production efficiency of the sill assembly, and can reduce the overall weight of the sill assembly.

[0079] The sills in the related art generally have a structure of stamped steel plates, including an inner plate and an outer plate. The inner plate and the outer plate are welded, and a cavity is formed between the inner plate and the outer plate. A plurality of strengthening structures are provided on the opposite surfaces of the inner plate and the outer plate to improve the structural strength of the inner plate and the outer plate, and further improve the structural strength of the sill. These strengthening structures are also all composed of steel parts, so that the overall sill structure is a steel structure, resulting in a relatively large weight of the sill, which is not conducive to the lightweight design of the sill assembly and the vehicle.

[0080] Furthermore, both the inner plate and the outer plate in the related art are of an integral structure. For example, the outer plate can be an integrally stamped steel plate structure. Since the integral outer plate is relatively long, there will be relatively large dimensional tolerances and low precision during the preparation process. Moreover, since the outer plate is relatively large, it is not conducive to correction and the adjustment cost is relatively high, resulting in a reduction in the production efficiency and manufacturing cost of the sill, and affecting the production efficiency and manufacturing cost of the vehicle.

[0081] The sill assembly and the vehicle provided by the present application will be described below with reference to the drawings and in combination with specific embodiments.

[0082] Referring to Figure 1 、 Figure 2 and Figure 3 ,the embodiments of the present application provide a sill assembly, which may include an outer sill mechanism 100, an inner sill mechanism 200, and a strengthening mechanism 300. The outer sill mechanism 100 and the inner sill mechanism 200 can be connected by welding, and a first cavity 140 can be formed between them. The strengthening mechanism 300 can be disposed in the first cavity 140.

[0083] Referring to Figure 3 ,the outer sill mechanism 100 may include an outer sill front section 110, an outer sill middle section 120, and an outer sill rear section 130 that are connected to each other. The outer sill front section 110 can be used to connect to the front apron of the vehicle body, the outer sill middle section 120 can be used to connect to the front floor of the vehicle body, and the outer sill rear section 130 can be used to connect to the rear floor of the vehicle body.

[0084] The front section 110 of the outer sill, the middle section 120 of the outer sill, and the rear section 130 of the outer sill can be sequentially connected along the length direction of the outer sill mechanism 100, and the front section 110 of the outer sill, the middle section 120 of the outer sill, and the rear section 130 of the outer sill can be connected by welding. The front section 110 of the outer sill, the middle section 120 of the outer sill, and the rear section 130 of the outer sill can all be of a stamping plate structure.

[0085] In this way, compared with setting the outer sill mechanism 100 as a whole structure, the outer sill mechanism 100 can include the front section 110 of the outer sill, the middle section 120 of the outer sill, and the rear section 130 of the outer sill that are connected to each other. During the processing and manufacturing process, it is easier to maintain the dimensional accuracy and reduce the dimensional tolerance. Setting the outer sill mechanism 100 as a three-section structure can facilitate adjustment and calibration, and when the dimensional tolerance of one or two sections is large, it can be adjusted separately, reducing material waste and adjustment time. Furthermore, setting the outer sill mechanism 100 as the front section 110 of the outer sill, the middle section 120 of the outer sill, and the rear section 130 of the outer sill, since the length of each section is relatively shorter than the whole, the probability of problems such as deformation during the processing of each section is relatively small, and the amount of deformation is also relatively small, facilitating structural adjustment and improving the production efficiency of the sill assembly.

[0086] In some examples, the inner sill mechanism 200 can be connected to the front section 110 of the outer sill, the middle section 120 of the outer sill, and the rear section 130 of the outer sill, and together enclose a first cavity 140. The first cavity 140 can extend along the length direction of the inner sill mechanism 200 and the outer sill mechanism 100 (such as Figure 2 the X direction in the figure). The inner sill mechanism 200 can also be connected to the front wall panel, the front floor, and the rear floor of the vehicle body. The inner sill mechanism 200 can also be welded to the front section 110 of the outer sill, the middle section 120 of the outer sill, and the rear section 130 of the outer sill by welding.

[0087] Referring to Figure 1 and Figure 2 in the figure, the strengthening mechanism 300 is disposed in the first cavity 140 and is connected to the inner wall of the inner sill mechanism 200 facing the first cavity 140. The strengthening mechanism 300 can extend along the length direction of the first cavity 140 and is disposed in the first cavity 140.

[0088] In this way, by arranging a strengthening structure in the first cavity 140 formed by the outer sill mechanism 100 and the inner sill mechanism 200, the structural strength of the sill assembly can be further improved, thereby improving the impact resistance of the sill assembly.

[0089] In some examples, the reinforcement mechanism 300 can be detachably connected to the inner threshold mechanism 200 facing the inner wall of the first cavity 140, which can improve the detachability convenience between the reinforcement mechanism 300 and the inner threshold mechanism 200, and facilitate the maintenance and replacement of the reinforcement mechanism 300.

[0090] In some examples, the density of the reinforcement mechanism 300 is less than that of the outer threshold mechanism 100 and the inner threshold mechanism 200. For example, the reinforcement mechanism 300 can be an aluminum alloy structural member, and the inner threshold mechanism 200 and the outer threshold mechanism 100 can be steel members.

[0091] In this way, by using a material with a density smaller than that of the inner threshold mechanism 200 and the outer threshold mechanism 100 to support the reinforcement mechanism 300, the structural strength of the threshold assembly can be ensured, and the weight of the threshold assembly can be reduced, which helps to realize the lightweight design of the threshold assembly and the vehicle.

[0092] In some embodiments of the present application, referring to Figure 1 and Figure 2 , the outer threshold mechanism 100 can be a steel member, and the inner threshold mechanism 200 can be a steel member. Specifically, both the outer threshold mechanism 100 and the inner threshold mechanism 200 can be stamped steel plates. In this way, it is convenient for the processing and manufacturing of the outer threshold mechanism 100 and the inner threshold mechanism 200, and the manufacturing cost of the outer threshold mechanism 100 and the inner threshold mechanism 200 can be reduced.

[0093] Furthermore, the accuracy of the stamped steel plate is relatively high compared with die-castings and extrusion structures, which can reduce machining and lower the grinding and calibration time.

[0094] If the outer threshold mechanism 100 includes an outer threshold front section 110, an outer threshold middle section 120, and an outer threshold rear section 130, then the outer threshold front section 110, the outer threshold middle section 120, and the outer threshold rear section 130 can all be separately stamped and formed. The stamped outer threshold front section 110, outer threshold middle section 120, and outer threshold rear section 130 can be connected by welding.

[0095] In some examples, the reinforcement mechanism 300 can be an aluminum member. For example, the reinforcement mechanism 300 can be an aluminum alloy extruded part, which can reduce the preparation time of the reinforcement mechanism 300. And since the reinforcement mechanism 300 is arranged in the first cavity 140 and plays a role in strengthening the threshold assembly, the accuracy requirement is relatively low, which can reduce the grinding time. Furthermore, by setting the reinforcement mechanism 300 as an aluminum member, the overall weight of the threshold assembly can be reduced, and thus the weight of the vehicle can be reduced.

[0096] In some embodiments of the present application, referring to Figure 3 and Figure 4, the inner sill structure 200 may include a front section 210 of the inner sill, a middle section 220 of the inner sill, and a rear section 230 of the inner sill. The front section 210 of the inner sill is connected to the front section 110 of the outer sill. The middle section 220 of the inner sill is connected to one end of the front section 210 of the inner sill and is also connected to the middle section 120 of the outer sill. The rear section 230 of the inner sill is connected to the end of the middle section 220 of the inner sill that faces away from the front section 210 of the inner sill and is connected to the rear section 130 of the outer sill.

[0097] The front section 210 of the inner sill, the middle section 220 of the inner sill, and the rear section 230 of the inner sill of the inner sill structure 200 are correspondingly connected to the front section 110 of the outer sill, the middle section 120 of the outer sill, and the rear section 130 of the outer sill of the outer sill structure 100, and jointly enclose a first cavity 140.

[0098] In some examples, the front section 210 of the inner sill and the front section 110 of the outer sill can be connected by welding. The middle section 220 of the inner sill and the middle section 120 of the outer sill can also be connected by welding. The rear section 230 of the inner sill and the rear section 130 of the outer sill can also be connected by welding.

[0099] In some embodiments of the present application, referring to Figure 2 and Figure 5 , the reinforcement mechanism 300 may include a reinforcing beam 310 and a connecting member 320. The reinforcing beam 310 is disposed in the first cavity 140 along the length extension direction of the first cavity 140 (such as the X direction in Figure 2 ). The reinforcing beam 310 can be an aluminum extrusion beam or an aluminum alloy extrusion beam, which can ensure the structural strength of the reinforcing beam 310 and reduce the weight of the reinforcing beam 310, so as to ensure the strength of the sill assembly and reduce the weight of the sill assembly.

[0100] In some examples, the reinforcing beam 310 can be welded to the wall surface of the inner sill structure 200 facing the inside of the first cavity 140 by welding. The reinforcing member can also be connected to the wall surface of the inner sill structure 200 through the connecting member 320.

[0101] In some examples, the inner sill structure 200 has a first inner wall 240 facing the inside of the first cavity 140. The connecting member 320 can be used to detachably connect one of the side walls in the width direction of the reinforcing beam 310 (such as the Y direction in Figure 2 and Figure 5 ) to the first inner wall 240. In this way, by providing the connecting member 320 to connect the reinforcing beam 310 to the inner sill structure 200, it is convenient to replace and repair the reinforcing beam 310, and the flexibility and practicality of the use of the inner sill assembly are improved.

[0102] In some examples, the connecting member 320 may be a threaded connecting member 320 such as a bolt, a screw or a screw. There may also be a plurality of connecting members 320. For example, there may be two connecting members 320, and the two connecting members 320 are respectively used to connect both ends in the length direction of the reinforcing beam 310 to the first inner wall 240. The more the number of connecting junctions, the more beneficial it is to improve the connection stability between the reinforcing beam 310 and the inner sill mechanism 200.

[0103] Based on the above embodiments, with reference to Figure 2 and Figure 6 , the reinforcing beam 310 and the inner sill mechanism 200 can also be connected by an adhesive method. The surface of the reinforcing beam 310 facing the first inner wall 240 has a filling groove 330, and the filling groove 330 is filled with an adhesive, and the adhesive is used to bond the reinforcing beam 310 and the first inner wall 240, so as to further improve the connection stability between the reinforcing beam 310 and the inner sill mechanism 200.

[0104] In some embodiments of the present application, with reference to Figure 2 , Figure 5 and Figure 6 , the strengthening mechanism 300 may further include at least one limiting connecting plate 340, and the limiting connecting plate 340 is disposed on the reinforcing beam 310.

[0105] In the height direction of the inner sill mechanism 200 (such as the Z direction in Figure 2 ), at least one end of the limiting connecting plate 340 is connected to the inner sill mechanism 200 and / or the outer sill mechanism 100 to limit the displacement of the reinforcing beam 310 in the height direction of the outer sill mechanism 100. The height direction of the inner sill mechanism 200 is perpendicular to the width direction of the reinforcing beam 310.

[0106] In this way, by connecting at least one end of the limiting connecting plate 340 to the inner sill mechanism 200 and / or the outer sill mechanism 100, the probability of the reinforcing beam 310 shaking or shifting in the height direction of the inner sill mechanism 200 can be reduced, and the connection stability between the reinforcing beam 310 and the inner sill mechanism 200 and / or the outer sill mechanism 100 can be improved. Moreover, when the door sill assembly is impacted, it can be avoided that the reinforcing beam 310 deflects in the height direction of the inner sill mechanism 200, and the reinforcing beam 310 can fully absorb the impact energy generated during the impact, thereby improving the impact resistance of the door sill beam assembly.

[0107] In some embodiments of the present application, with reference to Figure 2 , Figure 5 and Figure 6 , there may be a plurality of limiting connecting plates 340, and the plurality of connecting plates are all disposed on the reinforcing beam 310, and the plurality of connecting plates are arranged at intervals along the extending direction of the reinforcing beam 310.

[0108] In this way, by setting a plurality of limiting connection plates 340, the limiting ability of the limiting connection plates 340 to the reinforcing beam 310 in the height direction of the inner sill mechanism 200 can be further improved, and the connection stability between the strengthening mechanism 300 and the inner sill mechanism 200 and / or the outer sill mechanism 100 can be further improved.

[0109] In some examples, referring to Figure 2 and Figure 6 , there can be three limiting connection plates 340. One limiting connection plate 340 can be set at a position close to the head in the length direction of the reinforcing beam 310, another limiting connection plate 340 can be set at a position close to the tail in the length direction of the reinforcing beam 310, and there is also a limiting connection plate 340 set at a position close to the middle in the length direction of the reinforcing beam 310. The limiting connection plate 340 close to the head of the reinforcing beam 310 can be connected to the front section 110 of the outer sill of the outer sill mechanism 100 and / or the front section 210 of the inner sill of the inner sill mechanism 200. The limiting connection plate 340 close to the tail of the reinforcing beam 310 can be connected to the rear section 130 of the outer sill of the outer sill mechanism 100 and / or the rear section 230 of the inner sill of the inner sill mechanism 200. The limiting connection plate 340 close to the middle of the reinforcing beam 310 can be connected to the middle section 120 of the outer sill of the outer sill mechanism 100 and / or the middle section 220 of the inner sill of the inner sill mechanism 200.

[0110] In some embodiments of the present application, referring to Figure 2 and Figure 6 , the limiting connection plate 340 can include a clamping portion 341 and a first connection portion 343. The clamping portion 341 has a clamping groove 342, and the reinforcing beam 310 is inserted into the clamping groove 342. The clamping portion 341 is used to clamp the reinforcing beam 310 in the thickness direction of the reinforcing beam 310. The first connection portion 343 is connected to the clamping portion 341 and is located on one side of the reinforcing beam 310 in the height direction of the outer sill mechanism 100.

[0111] Referring to Figure 2 and Figure 6 , in the height direction of the inner sill mechanism 200 (such as the Z direction in Figure 2 ), the first connection portion 343 is used to be connected to the inner sill mechanism 200 and / or the outer sill mechanism 100.

[0112] In this way, the limiting connection plate 340 inserts the reinforcing beam 310 into the clamping groove 342 of the clamping portion 341 so that the clamping portion 341 clamps and fixes the reinforcing beam 310, which can improve the connection stability between the limiting connection plate 340 and the reinforcing beam 310. By using the first connection portion 343, the connection between the limiting connection plate 340 and the inner sill mechanism 200 and / or the outer sill mechanism 100 can be realized.

[0113] In some embodiments, the first connecting portion 343 can be connected to the inner sill mechanism 200 and / or the outer sill mechanism 100 by welding. The first connecting portion 343 can extend to the outside of the first cavity 140 and be welded to the inner sill mechanism 200 and / or the outer sill mechanism 100.

[0114] In some embodiments of the present application, referring to Figure 2 and Figure 6 , in the height direction of the inner sill mechanism 200 (such as the Z direction in Figure 2 ), the outer edge of the outer sill mechanism 100 has a first flanging 150 adapted to the first connecting portion 343. The first connecting portion 343 can be connected to the first flanging 150 by welding.

[0115] Referring to Figure 2 and Figure 6 , in the height direction of the inner sill mechanism 200 (such as the Z direction in Figure 2 ), the outer edge of the inner sill mechanism 200 has a second flanging 250 corresponding to the first connecting portion 343, and the first connecting portion 343 can also be connected to the second flanging 250 by welding.

[0116] If both the outer sill mechanism 100 and the inner sill mechanism 200 are provided with the first flanging 150 and the second flanging, the first flanging 150 and the second flanging 250 can simultaneously clamp the first connecting portion 343 and connect the first flanging 150, the first connecting portion 343 and the second flanging 250 by welding, so as to realize the connection of the reinforcing beam 310 to the outer sill mechanism 100 and the inner sill mechanism 200 through the limit connecting plate 340.

[0117] In some embodiments, if the inner sill mechanism 200 includes an inner sill front section 210, an inner sill middle section 220, and an inner sill rear section 230, then the inner sill front section 210, the inner sill middle section 220, and the inner sill rear section 230 can all be provided with the first flanging 150 to facilitate connection with the limit connecting plate 340.

[0118] Furthermore, if the outer sill mechanism 100 includes an outer sill front section 110, an outer sill middle section 120, and an outer sill rear section 130, then the outer sill front section 110, the outer sill middle section 120, and the outer sill rear section 130 can all be provided with the second flanging 250 to facilitate connection with the limit connecting plate 340.

[0119] In other embodiments, in the height direction of the inner sill mechanism 200, the outer edges of the opposite sides of the inner sill mechanism 200 can both be provided with the first flanging 150. The outer edges of the opposite sides of the outer sill mechanism 100 can also both be provided with the second flanging 250.

[0120] In some embodiments of the present application, referring to Figure 2 and Figure 6 , the limiting connection plate 340 may further include a second connection portion 344.

[0121] The second connection portion 344 is connected to a side of the clamping portion 341 facing away from the first connection portion 343. In the height direction of the inner sill mechanism 200, the reinforcing beam 310 is located between the first connection portion 343 and the second connection portion 344.

[0122] In this way, the connection stability between the limiting connection plate 340 and the inner sill mechanism 200 and / or the outer sill mechanism 100 can be improved, and the limiting effect of the limiting connection plate 340 on the reinforcing beam 310 in the height direction of the inner sill mechanism 200 can be improved.

[0123] In some examples, referring to Figure 2 and Figure 6 , in the height direction of the inner sill mechanism 200, if first flanges 150 are provided on both opposite sides of the inner sill mechanism 200 and second flanges 250 are provided on both opposite sides of the outer sill mechanism 100, the first connection portion 343 can be connected to the first flange 150 and / or the second flange 250 on one side, and the second connection portion 344 can be connected to the first flange 150 and / or the second flange 250 on the other side.

[0124] In some embodiments of the present application, referring to Figure 2 and Figure 6 , the reinforcing beam 310 has a second cavity 311 therein, and a reinforcing rib group 350 is provided in the second cavity 311. The reinforcing rib group 350 is connected to the inner wall of the second cavity 311.

[0125] In this way, by providing the reinforcing rib group 350 in the second cavity 311 of the reinforcing beam 310, the structural strength of the reinforcing beam 310 can be improved, and further the structural strength and impact resistance of the sill assembly can be improved.

[0126] In some embodiments of the present application, referring to Figure 5 and Figure 7 , the reinforcing rib group 350 may include first rib plates 351, and the first rib plates 351 can all extend along the length direction of the reinforcing beam 310. The reinforcing beam 310 has a first wall surface 312 and a second wall surface 313 which are oppositely arranged, and the first wall surface 312 and the second wall surface 313 are used to enclose the second cavity 311. One end of the first rib plate 351 is arranged on the first wall surface 312, and the other end of the first rib plate 351 is arranged on the second wall surface 313, so as to divide the second cavity 311 into two chambers by the first rib plate 351.

[0127] In some embodiments of the present application, referring to Figure 7, the stiffening rib group 350 may further include a second rib plate 352, and the second rib plates 352 can all extend along the length direction of the reinforcing beam 310. One end of the second rib plate 352 is arranged on the first wall surface 312, and the other end of the second rib plate 352 is arranged on the second wall surface 313. The first rib plates 351 and the second rib plates 352 are arranged at intervals, and the second cavity 311 of the reinforcing beam 310 is divided into three chambers.

[0128] In this way, by arranging two rib plates, the structural strength of the reinforcing beam 310 can be further improved, and the structural strength and impact resistance of the sill assembly can be improved.

[0129] In some embodiments of the present application, referring to Figure 7 , the stiffening rib group 350 may further include a third rib plate 353 and a fourth rib plate 354, and the third rib plate 353 and the fourth rib plate 354 can both extend along the length direction of the reinforcing beam 310. One end of the third rib plate 353 is connected to the connection part of the first rib plate 351 and the first wall surface 312, and the other end of the third rib plate 353 is connected to the second rib plate 352. One end of the fourth rib plate 354 is connected to the connection part of the first rib plate 351 and the second wall surface 313, and the other end of the fourth rib plate 354 is connected to the connection part of the second rib plate 352 and the third rib plate 353, so as to divide the second cavity 311 into five chambers.

[0130] In some embodiments of the present application, referring to Figure 7 , the stiffening rib group 350 may further include a fifth rib plate 355, and the fifth rib plate 355 can extend along the length direction of the reinforcing beam 310. The reinforcing beam 310 further has a third wall surface 314 for enclosing the second cavity 311. One end of the third wall surface 314 is connected to the first wall surface 312, and the other end of the third wall surface 314 is connected to the second wall surface 313. The second rib plate 352 is located between the third wall surface 314 and the first rib plate 351. One end of the fifth rib plate 355 is connected to the third wall surface 314, and the other end of the fifth rib plate 355 is connected to the side of the second rib plate 352 facing away from the first rib plate 351, so as to divide the second cavity 311 into six chambers.

[0131] In this way, on the basis of the above embodiments, by further arranging the fifth rib plate 355 in the second cavity 311, the structural strength of the reinforcing beam 310 can be further improved.

[0132] In some embodiments of the present application, referring to Figure 7 , the thickness of the first rib plate 351 (such as Figure 7As shown in FIG. L, it may be greater than or equal to 2 mm and less than or equal to 5 mm. For example, the thickness of the first rib plate 351 may be one of 2.3 mm, 2.6 mm, 3.1 mm, 3.6 mm, 4 mm, 4.2 mm, 4.5 mm, 4.7 mm, and 5 mm. Alternatively, the thickness of the first rib plate 351 may be any point value within the range of greater than or equal to 2 mm and less than or equal to 5 mm.

[0133] In this way, it is possible to avoid a reduction in the structural strength of the reinforcing beam 310 due to the too thin thickness of the first rib plate 351, and it is possible to avoid an increase in the manufacturing cost of the strengthening mechanism 300 due to the too thick thickness of the first rib plate 351.

[0134] In some embodiments, the thickness ranges of the second rib plate 352, the third rib plate 353, the fourth rib plate 354, and the fifth rib plate 355 can all be in the same thickness direction as that of the first rib plate 351.

[0135] In other embodiments, the thickness ranges of the first wall surface 312, the second wall surface 313, the third wall surface 314, and the fourth wall surface of the reinforcing beam 310 can all be greater than or equal to 2 mm and less than or equal to 5 mm. It is possible to avoid a relatively low structural strength of the reinforcing beam 310 due to the too thin wall thickness of the reinforcing beam 310, and it is possible to avoid an excessively high manufacturing cost of the reinforcing beam 310 due to the too large wall thickness of the reinforcing beam 310.

[0136] The embodiment of the present application also provides a vehicle, which may include a vehicle body and the above-mentioned sill assembly.

[0137] In this way, by using the above-mentioned sill assembly, the overall strength of the vehicle can be improved, and the assembly process of the vehicle can be reduced and the assembly efficiency of the vehicle can be improved.

[0138] In some embodiments, the vehicle may be a new energy vehicle (New Energy Vehicle), such as a pure electric vehicle (Pure Electric Vehicle / Battery Electric Vehicle; abbreviation: PEV / BEV), a range extended electric vehicle (Range Extended Electric Vehicle; abbreviation: REEV), a hybrid electric vehicle (Hybrid Electric Vehicle; abbreviation: HEV), a fuel cell electric vehicle), and the vehicle may also be any vehicle with a battery.
