A transition member extends along the first direction and includes a transition body plate and a second receiving portion. The transition body plate is connected to the sill beam, and the second receiving portion includes a first recessed portion corresponding to the clearance. The first recessed portion has a height difference with the two first receiving portions in the thickness direction, and the thickness direction intersects with the first direction.

Technical Field

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

[0002] For automakers, reducing overall vehicle costs has always been a key research focus in the automotive industry. Costs can be reduced through methods such as simplifying functions and configurations, changing materials and processes, and minimizing materials and weight.

[0003] Because different car models have different requirements, the matching boundaries between various components are different, resulting in the need for separate molds to manufacture the door sill beams for different models. Therefore, how to give the door sill beams universality without reducing their structural strength is an urgent problem to be solved. Utility Model Content

[0032] For automakers, reducing overall vehicle costs has always been a key research focus in the automotive industry. Costs can be reduced through methods such as simplifying functions and configurations, changing materials and processes, and minimizing materials and weight. Because different vehicle models have different requirements, the matching boundaries between various components differ, necessitating the separate molding and manufacturing of door sill beams for different models. Therefore, how to achieve universality for door sill beams without compromising their structural strength is a pressing issue that needs to be addressed.

[0033] To address the related technical problems, this application provides a vehicle that includes the vehicle floor assembly described below.

[0034] To address the related technical problems, this application also provides a vehicle floor assembly, for details please refer to [link / reference needed]. Figures 1 to 4 , Figure 1 This is a structural schematic diagram of an embodiment of the vehicle floor assembly provided in this application. Figure 2 yes Figure 1 The diagram shows the disassembled structure of the vehicle floor assembly. Figure 3 yes Figure 2 The diagram shows a structural schematic of one embodiment of the threshold beam. Figure 4 yes Figure 2 The diagram shows a structural schematic of one embodiment of the adapter.

[0035] The vehicle floor assembly 10 includes a vehicle floor 100, a sill beam 200, and a transition piece 300. The sill beam 200 extends along a first direction X. Two first receiving portions 210 are provided on one side of the sill beam 200 and spaced apart along the first direction X to form a clearance opening 220 between the two first receiving portions 210. The transition piece 300 extends along the first direction X and includes a transition main plate 310 and a second receiving portion 320. The transition main plate 310 is connected to the sill beam 200. The second receiving portion 320 includes a first recessed portion 321. The first recessed portion 321 is located in the clearance opening 220, and the first recessed portion 321 has a height difference with the two first receiving portions 210 in the thickness direction Z of the first receiving portion 210. The thickness direction Z intersects with the first direction X. The vehicle floor 100 overlaps the first receiving portion 210 and the first recessed portion 321.

[0036] The vehicle floor 100 serves as a structural support in the overall vehicle structure. Multiple spaced or alternating grooves and protrusions can be provided on the vehicle floor 100 to enhance its structural strength. Both ends of the vehicle floor 100 are connected to the door sill beams 200.

[0037] A sill beam 200 extends in a first direction X, which can be understood as the length direction of the vehicle floor 100. The sill beam 200 is connected to one side of the vehicle floor 100. Specifically, the sill beam 200 includes a sill body and two first receiving portions 210. The sill beam 200 includes a sill side end face near one end of the vehicle floor 100. The two first receiving portions 210 are connected to the sill side end face and are spaced apart in the first direction X, thereby forming a clearance 220 between the two first receiving portions 210. The two first receiving portions 210 are used to receive the vehicle floor 100.

[0038] The adapter 300 includes an adapter main plate 310 and a second receiving part 320. The adapter main plate 310 and the second receiving part 320 have an included angle. The adapter main plate 310 may be perpendicular to the second receiving part 320. Of course, in some other embodiments, the included angle between the adapter main plate 310 and the second receiving part 320 may also be an acute angle or an obtuse angle. The included angle relationship between the two can be set according to the actual situation. The transition main plate 310 is connected to the sill beam 200. Specifically, the transition main plate 310 can be connected to the side end face of the sill. The second receiving part 320 includes a first recessed part 321, which is correspondingly provided with the clearance opening 220. The first recessed part 321 has a height difference with the first receiving part 210 in the thickness direction Z. The thickness direction Z intersects with the first direction X, so that the first recessed part 321 and the first receiving part 210 form a recessed total receiving part. Thus, the first recessed part 321 and the first receiving part 210 can jointly support the vehicle floor 100. That is, the vehicle floor 100 overlaps the first receiving part 210 and the first recessed part 321, thereby increasing the overlap area of ​​the vehicle floor 100 and improving the structural strength of the vehicle floor assembly 10. In this embodiment, the vehicle floor assembly 10 includes two sill beams 200 and two adapters 300. One sill beam 200 and one adapter 300 are connected to one end of the vehicle floor 100, and the other sill beam 200 and adapter 300 are connected to the opposite end of the vehicle floor 100. The two sill beams 200 and the two adapters 300 are symmetrically arranged at both ends of the vehicle floor 100. In some other embodiments, the vehicle floor assembly 10 may include two sill beams 200 and one adapter 300. One sill beam 200 includes two first receiving portions 210 spaced apart in a first direction X, and an adapter 300 is provided between the two spaced-apart first receiving portions 210. The other sill beam 200 may include a general receiving portion, which can be understood as the two first receiving portions 210 being connected together at their opposite ends.

[0039] When manufacturing the sill beam 200, the sill beam 200 may include a main support portion forming a straight overlapping boundary for connection with a vehicle floor 100 having a straight boundary. When the sill beam 200 needs to be connected to a vehicle floor 100 with a recessed boundary, the main support portion can be cut to form two first support portions 210 spaced apart in a first direction X. A transition piece 300 is provided between the two first support portions 210, thereby forming a recessed boundary between the two first support portions 210 and the transition piece 300 for connection with a vehicle floor 100 with a recessed boundary. This allows the sill beam 200 to be applied to both vehicle floors 100 with straight boundaries and vehicle floors 100 with recessed boundaries.

[0040] Understandably, the attached diagram only shows one panel of the vehicle floor assembly 10; the sill beam and part of the seat crossbeams on the other side of the vehicle floor 100 are not shown in the diagram.

[0041] Through the above implementation, the sill beam 200 includes two first receiving portions 210 spaced apart along the first direction X, and the adapter 300 includes a first recessed portion 321, so that the sill beam 200 and the adapter 300 together form a recessed boundary that matches the vehicle floor 100, thereby giving the sill beam 200 a universal property without reducing the structural strength of the vehicle floor assembly 10.

[0042] In some embodiments, the adapter 300 includes a first overlapping edge 330, which is connected to one end of the adapter body plate 310 away from the second receiving portion 320. The end face of the sill beam 200 away from the first receiving portion 210 in the thickness direction Z is the upper sill face 230, and the first overlapping edge 330 overlaps with the upper sill face 230.

[0043] The adapter 300 includes a first overlapping edge 330, which is connected to the end of the adapter main plate 310 away from the second receiving portion 320 in the thickness direction Z. The sill beam 200 includes a sill upper surface 230 away from the first receiving portion 210 in the thickness direction Z, and the first overlapping edge 330 overlaps with the sill upper surface 230, thereby increasing the connection area between the adapter 300 and the sill beam 200. In addition, the adapter main plate 310 is connected to the sill side surface, and the sill side surface and the sill upper surface 230 are bent, thereby forming a Z-shaped cross-section structure for the adapter 300. This not only improves the connection strength between the adapter 300 and the sill beam 200, but also improves the structural strength of the adapter 300 itself. The second receiving part 320 also includes two connecting parts, which are respectively connected to one end of the first recessed part 321 in the first direction X. The two connecting parts have a height difference with the first recessed part 321, and the two connecting parts and the first recessed part 321 can be bent to reduce the local stress between the connecting parts and the first recessed part 321. The two connecting parts overlap one of the corresponding first receiving parts 210, thereby further improving the connection strength between the adapter 300 and the sill beam 200.

[0044] See Figure 5 , Figure 5 yes Figure 2 A schematic diagram of one embodiment of the vehicle floor is shown.

[0045] In some embodiments, the vehicle floor 100 includes a second overlapping edge 110 and a floor body 120. The floor body 120 includes a floor recess 121. The second overlapping edge 110 is connected to one end of the floor recess 121 near the sill beam 200. The floor recess 121 and the second overlapping edge 110 have a height difference. The second overlapping edge 110 overlaps with two first receiving portions 210 and first recess 321.

[0046] The second overlapping edge 110 is connected to the side of the floor body 120 near the sill beam 200 and is used to overlap the two first receiving parts 210 and the first recessed part 321. The floor body 120 includes a floor recessed part 121, which is recessed relative to the second overlapping edge 110. The recessed setting can be understood as a portion of the floor body 120 being recessed in the thickness direction Z towards the ground relative to the second overlapping edge 110, thereby creating a height difference between the floor recessed part 121 and the second overlapping edge 110. Thus, the recessed setting of the floor recessed part 121 of the vehicle floor 100 can improve the structural strength of the vehicle floor 100, increase the interior space of the cabin, and improve the comfort of the vehicle.

[0047] In some embodiments, the second overlapping edge 110 includes an overlapping body 112 and a second sunken portion 111. The second sunken portion 111 is sunken in the thickness direction Z toward the floor sunken portion 121. The overlapping body 112 overlaps with the first receiving portion 210, and the second sunken portion 111 overlaps with the first sunken portion 321.

[0048] The second overlapping edge 110 overlaps with the two first receiving portions 210. The portion of the second overlapping edge 110 corresponding to the clearance opening 220 is recessed, thereby forming an overlapping body 112 and a second recessed portion 111. This results in a concave-convex structure with convex sides on both sides of the second overlapping edge 110, which improves the structural strength of the second overlapping edge 110. In addition, the overlapping body 112 overlaps with the first receiving portion 210, and the second recessed portion 111 is correspondingly arranged with the first recessed portion 321 and overlaps with the first recessed portion 321. This allows the boundary of the vehicle floor 100 to match the boundary of the sill beam 200, improving the structural strength of the second overlapping edge 110 itself while also ensuring better connection strength between the second overlapping edge 110, the sill beam 200, and the adapter 300. In some embodiments, the adapter 300 includes a connecting portion that overlaps a portion of the first receiving portion 210 to improve the connection strength between the adapter 300 and the sill beam 200. Furthermore, the overlapping body 112 overlaps the boundary formed by the first receiving portion 210 and the connecting portion, i.e., the overlapping body 112, the first receiving portion 210, and the connecting portion have overlapping portions, thereby further improving the structural strength of the connection between the vehicle floor 100, the sill beam 200, and the adapter 300.

[0049] See Figure 6 , Figure 6 yes Figure 2 The diagram shows a structural schematic of one embodiment of the seat crossbeam.

[0050] In some embodiments, the second recessed portion 111 and the floor recessed portion 121 are on the same horizontal plane. The vehicle floor assembly 10 includes a seat crossbeam 400, which extends along a second direction Y intersecting the first direction X and the thickness direction Z. The seat crossbeam 400 is connected to the floor recessed portion 121. One end of the seat crossbeam 400 near the sill beam 200 is provided with an overlap portion 430. One end of the seat crossbeam 400 in the second direction Y corresponds to the second recessed portion 111. The overlap portion 430 overlaps with the first overlap edge 330.

[0051] The vehicle floor assembly 10 also includes a seat crossbeam 400, which extends along a second direction Y. Both ends of the seat crossbeam 400 are connected to the sill beam 200. The second direction Y intersects with the first direction X and the thickness direction Z. The second direction Y can refer to the width direction of the vehicle floor 100. Specifically, the second recessed portion 111 and the floor recessed portion 121 are on the same horizontal plane, which can refer to the plane formed by the first direction X and the second direction Y. The seat crossbeam 400 is connected to the floor recessed portion 121, and the end of the seat crossbeam 400 near the sill beam 200 in the second direction Y extends to correspond to the second recessed portion 111. The end of the seat crossbeam 400 near the sill beam 200 has an overlapping portion 430, which overlaps with the first overlapping edge 330. Therefore, the second recessed portion 111 and the floor recessed portion 121 are on the same horizontal plane, allowing the second recessed portion 111 to avoid the seat crossbeam 400, and the overlapping portion 430 overlaps the first overlapping edge 330, so that the area of ​​the seat crossbeam 400 corresponding to the sill beam 200 in the second direction Y is maximized. When impacted, the sill beam 200 and the seat crossbeam 400 have a larger contact area, thereby improving the force transmission effect between the seat crossbeam 400 and the sill beam 200 and improving the impact performance of the vehicle floor assembly 10. Of course, in some other embodiments, the floor recessed portion 121 may be set further down than the second recessed portion 111, that is, in the thickness direction Z, the overlapping body 112, the second recessed portion 111 and the floor recessed portion 121 are arranged in sequence; or, the second recessed portion 111 is set further down than the floor recessed portion 121, that is, in the thickness direction Z, the overlapping body 112, the floor recessed portion 121 and the second recessed portion 111 are arranged in sequence.

[0052] In some embodiments, the seat crossbeam 400 includes a reinforcing protrusion 410 and a crossbeam body 420. The reinforcing protrusion 410 is located on one side of the crossbeam body 420 in a first direction X. Both the crossbeam body 420 and the reinforcing protrusion 410 are connected to the floor recess 121.

[0053] The seat crossbeam 400 is used to mount a seat. The seat crossbeam 400 includes a crossbeam body 420 and reinforcing protrusions 410. Both the crossbeam body 420 and the reinforcing protrusions 410 are connected to the floor recess 121. The reinforcing protrusions 410 are connected to one end of the crossbeam body 420 in the first direction X, thereby improving the structural strength of the seat crossbeam 400. Both the crossbeam body 420 and the reinforcing protrusions 410 are connected to the seat, making the connection between the seat and the seat crossbeam 400 more secure, and making the seat more stable when subjected to acceleration in the first direction X. In this embodiment, cavities are formed between the crossbeam body 420 and the reinforcing protrusions 410 and the floor recess 121, which can improve the structural strength of the seat crossbeam 400. In other embodiments, there may be multiple reinforcing protrusions 410, which can be connected to both ends of the crossbeam body 420 in the first direction X to further improve the structural strength of the seat crossbeam 400 and enhance the stability of the seat.

[0054] In some embodiments, the reinforcing protrusion 410 is provided with a mounting area 411, which gradually protrudes from the beam body 420 in a first direction X.

[0055] The reinforcing protrusion 410 is provided with a mounting area 411, which can be understood as the area where the reinforcing protrusion 410 connects to the seat. The mounting area 411 gradually protrudes from the crossbeam body 420 in the first direction X, meaning that the distance between the mounting area 411 and its two ends in the second direction Y and the crossbeam body 420 gradually decreases, causing the reinforcing protrusion 410 to form a triangular-like structure. Of course, in other embodiments, the reinforcing protrusion 410 can also be other shapes, such as square or trapezoidal. See the mounting area 411. Figure 6As shown in the dashed box (this dashed box is for illustrative purposes only), the mounting area 411 may have mounting holes, through which the seat connects to the reinforcing protrusion 410. This reduces the area of ​​the non-mounting area outside the mounting area 411, improving the structural strength of the reinforcing protrusion 410 while reducing its area and thus the weight of the seat beam 400. This achieves both improved structural strength and weight reduction. In this embodiment, there may be two reinforcing protrusions 410. These two protrusions are connected to one end of the beam body 420 in the first direction X, and are spaced apart in the second direction Y, thereby increasing the connection point between the seat beam 400 and the seat and improving seat stability. Furthermore, the two reinforcing protrusions 410 are symmetrically arranged along the centerline of the floor body 120 in the first direction X, resulting in a more balanced stress distribution on the seat beam 400. In some other embodiments, the number of reinforcing protrusions 410 may be greater, with multiple reinforcing protrusions 410 connected to the same end of the beam body 420 in the first direction X, and symmetrically arranged along the centerline of the floor body 120 in the first direction X. Of course, based on this, multiple reinforcing protrusions 410 may also be connected to both ends of the beam body 420 in the first direction X.

[0056] In some embodiments, the floor body 120 includes a floor protrusion 122 and a floor connecting portion 123. The floor protrusion 122, the floor connecting portion 123 and the floor recess 121 are connected sequentially in the first direction X. The floor protrusion 122 is spaced apart from the clearance opening 220 in the first direction X, and the floor protrusion 122 is spaced apart from the floor recess 121 in the thickness direction Z.

[0057] The floor body 120 includes a raised portion 122 and a connecting portion 123. The raised portion 122 is connected to a recessed portion 121 in the first direction X via the connecting portion 123. The raised portion 122 and the recessed portion 121 are spaced apart in the thickness direction Z, creating a height difference between them. This forms a concave-convex structure, thereby improving the structural strength of the floor body 120. The raised portion 122 is used to connect with the rear seats. Thus, the recessed portion 121 corresponds to the occupant's activity space. This arrangement of the recessed portion 121 and the raised portion 122 provides a larger activity space for the occupant while also increasing the structural strength of the floor body 120. A second overlapping portion 430 can also be connected to the outer end of the raised portion 122 for overlapping with other components. In addition, a rear crossbeam (not shown) can be connected to the side of the floor protrusion 122 near the floor recess 121, and the rear seats can be connected to the floor protrusion 122 and the rear crossbeam, thereby improving the stability of the rear seats.

[0058] In some embodiments, the seat crossbeam 400 may include an overlap joint connected to the end of the crossbeam body 420, and an overlap portion 430 disposed at the overlap joint to connect with the first overlap edge 330. The overlap portion and the crossbeam body 420 form an end cavity, thereby improving the structural strength of the end of the seat crossbeam 400. Furthermore, the portions corresponding to the floor recess 121 and the second recess 111 are provided with floor protrusions extending in the second direction Y, thereby improving the structural strength of the vehicle floor 100. The dimension of the seat crossbeam 400 in the second direction Y is larger than the dimension of the floor protrusion in the second direction Y, and the floor protrusion is connected to the side of the seat crossbeam 400. The two ends of the seat crossbeam 400 in the first direction X are connected to the floor recess 121, thereby forming two first crossbeam reinforcing cavities with the seat crossbeam 400 and the floor protrusion. The two first crossbeam reinforcing cavities are located at the two ends of the floor protrusion in the first direction X, which can improve the structural strength of the vehicle floor assembly 10. Furthermore, the floor protrusion does not extend to the second recess 111, thereby forming a second crossbeam reinforcement cavity between the end of the seat crossbeam 400 and the second recess 111, which can improve the structural strength of the end of the vehicle floor assembly 10 in the second direction Y.

[0059] In some embodiments, the two first receiving parts 210 are provided with positioning ribs 211 at their close ends, and the positioning ribs 211 are connected to the side of the first receiving part 210 away from the vehicle floor 100 and the door sill beam 200.

[0060] Positioning ribs 211 are located at opposite ends of the two first receiving portions 210, and connect the side of the first receiving portion 210 away from the vehicle floor 100 and the sill beam 200. This arrangement does not affect the overlap of the vehicle floor 100 with the first receiving portion 210, and the positioning ribs 211 also improve the structural strength of the opposite end of the first receiving portion 210, increasing the weight that the first receiving portion 210 can bear. When manufacturing the sill beam 200, the two first receiving portions 210 of the sill beam 200 are connected together to form a total receiving portion. The two positioning ribs 211 are set at a designed interval, at which point the sill beam 200 forms a straight overlap boundary, which can be used to connect the vehicle floor 100, which has a straight boundary. The sill beam 200 of this application can be obtained by cutting away the total receiving portion located between the two positioning ribs 211 through the positioning ribs 211, allowing the positioning ribs 211 to serve a positioning function.

[0061] In summary, the sill beam 200 includes two first receiving portions 210 spaced apart along the first direction X, and the adapter 300 includes a first recessed portion 321, so that the sill beam 200 and the adapter 300 together form a recessed boundary that matches the vehicle floor 100, thereby giving the sill beam 200 a universal property without reducing the structural strength of the vehicle floor assembly 10.
