Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a floor assembly for a vehicle and the vehicle itself. Background Technology

[0002] Currently, among various types of vehicle collisions (such as gasoline vehicles and new energy vehicles), side collisions have the second highest fatality rate after frontal collisions. Therefore, it is necessary to improve the vehicle's resistance to side collisions to reduce injuries to occupants and protect battery safety in accidents.

[0003] In related technologies, if a vehicle is involved in a side collision, the distance between the occupant and the inner door panel is relatively close (e.g., about 25cm), and the occupant is likely to suffer serious injury due to the impact. Furthermore, if the deformation of the beam structure in the vehicle's floor assembly is large, there is a risk of puncture or severe impact on the battery pack, posing a high-voltage safety hazard. Utility Model Content

[0004] In view of this, this application aims to provide a vehicle floor assembly to improve the collision resistance performance of the floor assembly.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0006] A floor assembly for a vehicle includes: a floor body; a seat crossbeam disposed on the side of the floor body facing the passenger compartment, and the seat crossbeam having first crushing portions at both ends in the Y direction; a lower longitudinal beam disposed on the side of the floor body away from the passenger compartment; and a connecting plate disposed on the side of the floor body away from the passenger compartment and arranged along the Y direction, and the connecting plate being connected to the lower longitudinal beam at its inner end in the Y direction.

[0007] According to some embodiments of this application, the floor body forms a central channel that rises toward the passenger compartment and extends in the X direction, and the seat crossbeam is provided with a clearance portion that is adapted to clear the central channel.

[0008] According to some embodiments of this application, the seat crossbeam includes: a first beam segment disposed on one side of the central channel in the Y direction, and one end of the first beam segment being connected to the side wall of the central channel; a second beam segment disposed on the other side of the central channel in the Y direction, and one end of the second beam segment being connected to the other side wall of the central channel; and two first crushing segments forming the first crushing portion, and the two first crushing segments being respectively connected to the end of the first beam segment away from the central channel and the end of the second beam segment away from the central channel.

[0009] According to some embodiments of this application, the seat crossbeam includes: a main crossbeam section, the middle of which is raised towards the passenger compartment to form the clearance portion; two second crushing sections, which form the first crushing portion, and the two second crushing sections are respectively connected to both ends of the main crossbeam section in the Y direction.

[0010] According to some embodiments of this application, the floor assembly further includes a first reinforcing plate, which is connected to the side of the floor body away from the passenger compartment, and the first reinforcing plate and the central channel are disposed opposite each other in the Z direction.

[0011] According to some embodiments of this application, a first cavity is formed between the seat crossbeam and the floor body, and the floor assembly further includes a second reinforcing plate disposed in the first cavity and connected to the seat crossbeam.

[0012] According to some embodiments of this application, the seat crossbeam includes a first crossbeam and a second crossbeam, the first crossbeam and the second crossbeam being arranged at intervals in the X direction.

[0013] According to some embodiments of this application, the connecting plate includes: a first connecting plate, which is correspondingly disposed with the first crossbeam in the Z direction; and / or a second connecting plate, which is correspondingly disposed with the second crossbeam in the Z direction.

[0014] According to some embodiments of this application, a second cavity is formed between the connecting plate and the floor body, and the connecting plate has a second crushing portion.

[0015] Compared to existing technologies, the floor assembly described in this application has the following advantages:

[0016] (1) A first crushing part is provided at the end of the seat beam in the Y direction to improve the absorption effect of the seat beam end on the side collision energy, reduce the collision energy transmitted to the middle of the seat beam, and thus prevent the seat beam from intruding into the passenger compartment space due to the large deformation caused by the side collision.

[0017] (2) A connecting plate is provided at the bottom of the floor body. The connecting plate is provided with a second crushing part. The deformation energy absorption performance of the connecting plate can be improved through the second crushing part, thereby reducing the impact force transmitted to the lower longitudinal beam, preventing the lower longitudinal beam from deforming and bending inward due to lateral impact, reducing the risk of damage to the lower longitudinal beam, and thus protecting the battery arranged inside the lower longitudinal beam.

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0045] The following will refer to Figures 1-14 The floor assembly 100 of the present application will be described in detail with reference to the embodiments.

[0046] Combination Figure 1 and Figure 2 As shown, the vehicle floor assembly 100 according to an embodiment of this application includes: a floor body 1, a seat crossbeam 2, a lower longitudinal beam 3, and a connecting plate 4.

[0047] Reference Figure 1 As shown, the seat beam 2 is located on the side of the floor body 1 facing the passenger compartment, and the seat beam 2 is provided with a first crushing part 201 at both ends in the Y direction. The first crushing part 201 is adapted to crush and absorb energy when subjected to collision force, so as to reduce the collision force transmitted to the middle position of the seat beam 2. The deformation mode of the seat beam 2 under the side collision force is controlled. By reducing the deformation of the seat beam 2, the damage caused by the seat beam 2 to the occupants in the passenger compartment or the battery under the floor assembly 100 is reduced.

[0048] like Figure 1 and Figure 2 As shown, the lower longitudinal beam 3 is located on the side of the floor body 1 facing away from the passenger compartment, in order to improve the structural strength and longitudinal deformation resistance of the floor assembly 100. Among other things, Figure 1 and Figure 2 Only one lower longitudinal beam 3 is shown in the diagram. The floor assembly 100 may have two lower longitudinal beams 3, and the two lower longitudinal beams 3 are arranged at intervals in the X direction of the vehicle. A space for arranging the battery can be formed between the two lower longitudinal beams 3, and the two lower longitudinal beams 3 can protect the battery in the Y direction to prevent the collision force in the Y direction from acting on the battery.

[0049] Combination Figure 1 , Figure 6 and Figure 7 As shown, the connecting plate 4 is also arranged on the side of the floor body 1 away from the crew compartment, and the connecting plate 4 is arranged along the Y direction. Moreover, the inner end of the connecting plate 4 in the Y direction is connected to the lower longitudinal beam 3.

[0050] It should be noted that the "X-direction" refers to the vehicle's forward and backward direction, the "Y-direction" refers to the vehicle's left and right direction, and the "Z-direction" refers to the vehicle's vertical direction. The "inner end" of the connecting plate 4 refers to the end of the connecting plate 4 closest to the vehicle's centerline.

[0051] Furthermore, the connecting plate 4 extends along the Y direction, and the outer end of the connecting plate 4 is located near the end of the floor body 1 in the Y direction, so that the impact force transmitted to the floor assembly 100 in the lateral direction can act on the connecting plate 4, and the connecting plate 4 can further transmit the impact force to the lower longitudinal beam 3, so as to further disperse the impact force through the lower longitudinal beam 3 and reduce the damage caused by the impact force to the floor assembly 100.

[0052] The connecting plate 4 can transfer the lateral impact force to the lower longitudinal beam 3, and further transfer the impact force through the lower longitudinal beam 3, thereby reducing the destructiveness of the impact force and reducing the degree of damage and deformation of the floor assembly 100, and avoiding excessive encroachment on the passenger compartment or battery arrangement space due to the deformation of the floor assembly 100.

[0053] Therefore, when the floor assembly 100 of this embodiment is subjected to a lateral impact force, the first crushing portion 201 formed on the upper end of the seat beam 2 in the Y direction can be crushed and deformed under the action of the impact force to absorb the impact energy and reduce the damage caused by the impact force to the main body of the seat beam 2 (i.e., the part near the center of the vehicle, such as the central channel 11 area of ​​the floor assembly 100), thereby weakening it by absorbing energy along the transmission path of the impact force. At the same time, the connecting plate 4 located at the lower part of the floor body 1 can also transmit the impact force to the lower longitudinal beam 3 side to disperse the impact force through the lower longitudinal beam 3 and reduce the damage caused by the impact force to the floor assembly 100.

[0054] It is understandable that the floor body 1 is provided with seat beams 2 and connecting plates 4 on both sides in the Z direction, which can improve the deformation resistance of the floor assembly 100 against lateral impact forces, reduce the deformation of the floor assembly 100 under the action of lateral impact forces, and thus prevent excessive intrusion on the passenger compartment side, or the lateral impact force acting on the battery and causing high voltage safety problems due to the impact, thereby improving the driving safety and reliability of the whole vehicle.

[0055] It should be noted that currently, among various vehicle types (such as gasoline vehicles and new energy vehicles), side-impact collisions have the second highest fatality rate after frontal collisions. Therefore, it is necessary to improve the vehicle's resistance to side-impact collisions to reduce occupant injuries and protect battery safety. In related technologies, if a side-impact collision occurs, the distance between the occupant and the inner door panel is relatively short (e.g., around 25cm), making the occupant susceptible to severe injury from the impact. Furthermore, if the beam structure in the vehicle's floor assembly 100 (e.g., seat crossbeams 2) deforms significantly, there is a risk of puncture or severe impact to the battery pack, posing a high-voltage safety hazard.

[0056] In this application, the seat crossbeam 2 is arranged laterally on the floor body 1, with both ends of the seat crossbeam 2 adjacent to the side panels of the vehicle (such as the B-pillar, doors, etc.). When the vehicle is subjected to a side collision, the first crushing portion 201 on the seat crossbeam 2 can absorb the collision energy, thereby limiting the deformation of the seat crossbeam 2 caused by the side collision force (i.e., the deformation at the ends of the seat crossbeam 2 is large while the deformation in the middle area is small), preventing the seat crossbeam 2 from intruding too much into the passenger compartment space. At the same time, the connecting plate 4 under the floor body 1 can transfer the side collision force to the longitudinal beam, thereby reducing the lateral deformation of the floor assembly 100 caused by the side collision force. This can protect the battery located in the area under the floor assembly 100, reduce the impact on the area where the battery is located, thereby reducing the risk of high-voltage safety problems and improving the overall vehicle's driving safety and reliability.

[0057] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the floor body 1 forms a central passage 11 that rises towards the passenger compartment and extends in the X direction. The seat crossbeam 2 is provided with a clearance portion adapted to avoid the central passage 11, thereby improving the fit between the seat crossbeam 2 and the floor body 1 and preventing the seat crossbeam 2 from occupying excessive vertical space.

[0058] Understandably, the vehicle also includes seats, positioned above the seat crossbeam 2. The seat crossbeam 2 can connect and cooperate with the seats to enhance the structural strength of the seat area. Additionally, when a battery is installed in the vehicle, it can be positioned directly below the floor assembly 100, which is also below the central tunnel 11.

[0059] like Figure 1 As shown, in some embodiments of this application, the seat beam 2 includes: a first beam segment 231, a second beam segment 232, and two first crushing segments 233.

[0060] Specifically, the first beam segment 231 is located on one side of the central channel 11 in the Y direction, and one end of the first beam segment 231 is connected to the side wall of the central channel 11. The second beam segment 232 is located on the other side of the central channel 11 in the Y direction, and one end of the second beam segment 232 is connected to the other side wall of the central channel 11. The first crushing segment 233 forms the first crushing part 201, and the two first crushing segments 233 are respectively connected to the end of the first beam segment 231 away from the central channel 11 and the end of the second beam segment 232 away from the central channel 11.

[0061] The first beam segment 231 extends along the Y-direction, with its outer end connected to the first crushing segment 233 and its inner end connected to the side wall of the central passage 11. The second beam segment 232 also extends along the Y-direction, with its outer end connected to the first crushing segment 233 and its inner end connected to the side wall of the central passage 11. Thus, the seat crossbeam 2 is constructed as two beam segments arranged on both sides of the central passage 11 in the Y-direction, allowing the seat crossbeam 2 to avoid obstructing the space above the central passage 11. In other words, the inner ends of the first beam segment 231 and the second beam segment 232 are spaced apart in the Y-direction to avoid obstructing the space above the central passage 11.

[0062] Furthermore, the first crushing section 233 is connected to the outer end of the first beam section 231 or the second beam section 232, thereby arranging the first crushing section 233 in the floor assembly 100 in an area suitable for bearing the lateral impact force at the first moment, so as to fully absorb and weaken the lateral impact force through the first crushing part 201 on the first crushing section 233.

[0063] It should be noted that the first crushing part 201 can be constructed as a crushing groove or other crushing structure. The specific construction of the first crushing part 201 can be designed based on the size of the first crushing section 233, so as to ensure the effect of the first crushing part 201 crushing deformation to absorb collision energy.

[0064] In some embodiments of this application, the first crushing section 233 can be integrally formed with the first beam section 231 or the second beam section 232, thereby reducing the number of parts in the seat crossbeam 2, saving assembly steps, and improving assembly efficiency.

[0065] like Figure 1 As shown, in some embodiments of this application, the seat beam 2 includes: a main beam section 241 and two second crushing sections 242.

[0066] The main body section 241 of the crossbeam is raised towards the passenger compartment in the middle to form a clearance section in the middle region of the main body section 241, so that the main body section 241 can be arranged across the top of the central passage 11. The second crushing section 242 forms the first crushing section 201 mentioned above, and the two second crushing sections 242 are respectively connected to the two ends of the main body section 241 in the Y direction. In this way, the second crushing sections 242 arranged on both sides of the main body section 241 in the Y direction absorb and weaken the lateral collision energy, thereby reducing the collision energy transmitted to the main body section 241, reducing the deformation and damage at the main body section, and thus effectively reducing the damage to the floor assembly 100 caused by the lateral collision.

[0067] It is understandable that the main beam section 241, by forming an upward-protruding bulge structure in the middle (which is also the passenger compartment side), can create a clearance area (i.e., the clearance part mentioned above) below the bulge structure, thereby clearing the central passage 11. Furthermore, the bulge structure can also be fitted to the upper surface of the central passage 11 using connecting structures such as flanges, thereby increasing the structural strength of the main beam section 241 and the floor body 1 at the connection point.

[0068] In some embodiments of this application, the two second crushing sections 242 can be integrally formed with the main body section 241 of the crossbeam, thereby reducing the number of parts in the seat crossbeam 2, saving assembly steps, and improving assembly efficiency.

[0069] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the height of the central aisle 11 relative to the floor body 1 gradually decreases from front to back. When the seat beam 2 is arranged in an area where the height of the central aisle 11 is relatively low, the seat beam 2 can be constructed as a beam structure spanning the central aisle 11 (i.e., the middle of the beam body section 241 forms an upward bulge structure), thereby ensuring the continuity of the seat beam 2, reducing the number of components in the floor assembly 100, reducing the assembly difficulty of the floor assembly 100, and preventing the seat beam 2 from occupying too much space on the passenger compartment side, thus meeting the arrangement requirements of the devices on the passenger compartment side.

[0070] In some embodiments of this application, the floor assembly 100 further includes a first reinforcing plate 251, which is connected to the side of the floor body 1 away from the passenger compartment, and the first reinforcing plate 251 and the central channel 11 are arranged opposite to each other in the Z direction.

[0071] Combination Figure 8 and Figure 14 , Figure 9 and Figure 13 As shown, the first reinforcing plate 251 is arranged in the lower area of ​​the central channel 11, and the first reinforcing plate 251 can be arranged to protrude upward, so that at least part of the first reinforcing plate 251 is placed in the downward open space of the central channel 11, thereby improving the structural strength of the central channel 11 while reducing the space occupied by the first reinforcing plate 251, so as to reserve sufficient clearance space under the floor body 1.

[0072] Understandable, Figure 8 and Figure 14 Corresponding to the arrangement scheme of the seat crossbeam 2, there is a first beam segment 231 and a second beam segment 232 arranged on both sides of the central channel 11 in the Y direction; Figure 9 and Figure 13 The arrangement scheme corresponding to the seat crossbeam 2 spanning the central aisle 11. (Refer to...) Figure 8 and Figure 9 As shown, the specific structural parameters of the first reinforcing plate 251 can be set according to the position of the first reinforcing plate 251 corresponding to the central channel 11, thereby improving the compatibility between the first reinforcing plate 251 and the floor body 1, and thus better enhancing the support and reinforcement effect of the first reinforcing plate 251 on the central channel 11.

[0073] like Figure 13 and Figure 14 As shown, in the first embodiment of this application, a first cavity 101 is formed between the seat beam 2 and the floor body 1, and the floor assembly 100 also includes a second reinforcing plate 252, which is arranged in the first cavity 101 and connected to the seat beam 2.

[0074] Combination Figure 1 , Figure 13 and Figure 14 As shown, the seat beam 2 is arranged on the upper surface of the floor body 1, and the seat beam 2 forms a groove structure that opens to one side of the floor body 1. The seat beam 2 can be connected to the floor body 1 through the flange structure formed at the open end of the groove structure, and the seat beam 2 and the floor body 1 cooperate to form the first cavity 101 mentioned above.

[0075] The second reinforcing plate 252 extends in the Y direction in the first cavity 101, and at least part of the second reinforcing plate 252 is arranged in contact with the inner wall surface of the top wall of the seat beam 2, so as to improve the deformation resistance of the seat beam 2 in the Y direction through the second reinforcing plate 252.

[0076] It is understandable that when the seat crossbeam 2 is composed of a first beam segment 231, a second beam segment 232, and two first crushing segments 233, there can be two second reinforcing plates 252, and the two second reinforcing plates 252 can be connected and cooperate with the first beam segment 231 and the second beam segment 232 respectively. Preferably, the second reinforcing plates 252 are arranged at the position of the first beam segment 231 and the second beam segment 232 near the central channel 11, so as to fully improve the deformation resistance of the first beam segment 231 and the second beam segment 232 near the central channel 11, and prevent the first beam segment 231 or the second beam segment 232 from intruding into the passenger compartment due to large deformation caused by the collision force; when the seat crossbeam 2 is composed of a crossbeam main body segment 241 and two second crushing segments 242, the second reinforcing plates 252 can be arranged in the area of ​​the crossbeam main body segment 241 near the central channel 11 to improve the structural strength of the crossbeam main body segment 241.

[0077] like Figure 1 and Figure 2As shown, in some embodiments of this application, the seat crossbeam 2 includes a first crossbeam 21 and a second crossbeam 22, which are arranged at intervals in the X direction. That is, two seat crossbeams 2 (i.e., the first crossbeam 21 and the second crossbeam 22) are provided in the floor assembly 100, and the two seat crossbeams 2 correspond to the front and rear rows of seats in the vehicle, respectively.

[0078] The first crossbeam 21 can be constructed as the seat crossbeam 2 consisting of the first beam segment 231, the second beam segment 232, and two first crushing segments 233; the second crossbeam 22 can be constructed as the seat crossbeam 2 consisting of the main beam segment 241 and two second crushing segments 242. It is understood that the specific construction of the seat crossbeam 2 can be adaptively designed and adjusted according to its position within the floor body 1.

[0079] Combination Figure 1 and Figure 6 As shown, in some embodiments of this application, the connecting plate 4 includes a first connecting plate 41, which is correspondingly arranged with the first crossbeam 21 in the Z direction, so as to further enhance the Y-direction resistance of the floor assembly 100 in the area where the first crossbeam 21 is located by arranging the first connecting plate 41.

[0080] Combination Figure 1 and Figure 7 As shown, in some embodiments of this application, the connecting plate 4 includes a second connecting plate 42, which is correspondingly arranged with the second crossbeam 22 in the Z direction, so as to further enhance the Y-direction deformation resistance of the floor assembly 100 in the area where the second crossbeam 22 is located by arranging the second connecting plate 42.

[0081] It is understandable that when the floor assembly 100 is provided with the aforementioned first crossbeam 21 and second crossbeam 22, a first connecting plate 41 and a second connecting plate 42 structure can be arranged below the first crossbeam 21 and the second crossbeam 22 respectively to further improve the side impact resistance performance of the floor assembly 100.

[0082] Combination Figure 1 , Figure 13 and Figure 14 As shown, in some embodiments of this application, a second cavity 102 is formed between the connecting plate 4 and the floor body 1, and a second crushing part 401 is formed in the connecting part. The second crushing part 401 is adapted to crush and deform when subjected to a Y-direction collision force, so as to absorb the collision force in the transmission path of the collision force and reduce the collision force transmitted to the downward longitudinal beam 3.

[0083] It is understandable that the structural strength of the floor assembly 100 is improved by forming a second cavity 102 between the connecting plate 4 and the base plate body. At the same time, the second crushing part 401 is formed on the connecting plate 4 to absorb the collision energy transmitted to the lower longitudinal beam 3 in the Y direction, reduce the impact force on the lower longitudinal beam 3, reduce the degree of damage to the lower longitudinal beam 3, and prevent the lower longitudinal beam 3 from deforming inward and further acting the impact force on the battery, thereby improving the protection effect of the floor assembly 100 on the battery.

[0084] It should be noted that the second crushing part 401 can be constructed as a crushing groove or other crushing structure. The specific construction of the second crushing part 401 is not limited to a crushing groove. Furthermore, the number and arrangement of the second crushing part 401 on the connecting plate 4 can be set according to the energy absorption requirements and strength requirements of the floor assembly 100 at the connecting plate 4, and no specific limitation is made here.

[0085] When multiple second crushing parts 401 are provided on the connecting plate 4, the multiple second crushing parts 401 can be arranged sequentially at intervals along the Y direction, thereby improving the energy absorption effect of the second crushing parts 401 on the collision force in the Y direction and reducing the collision energy transmitted to the downward longitudinal beam 3.

[0086] The floor assembly 100 according to the embodiments of this application has at least the following advantages over the prior art:

[0087] (1) A first crushing part 201 is provided at the end of the seat beam 2 in the Y direction to improve the absorption effect of the end of the seat beam 2 on the side collision energy, reduce the collision energy transmitted to the middle of the seat beam 2, and thus prevent the seat beam 2 from intruding into the passenger compartment space due to the large deformation caused by the side collision.

[0088] (2) A connecting plate 4 is provided at the lower part of the floor body 1. The connecting plate 4 is provided with a second crushing part 401. The deformation energy absorption performance of the connecting plate 4 can be improved by the second crushing part 401, thereby reducing the impact force transmitted to the lower longitudinal beam 3, preventing the lower longitudinal beam 3 from deforming and bending inward due to lateral impact, reducing the risk of damage to the lower longitudinal beam 3, and thus protecting the battery arranged inside the lower longitudinal beam 3.

[0089] (3) A second reinforcing plate 252 is provided in the first cavity 101 formed between the seat beam 2 and the base plate body. The second reinforcing plate 252 improves the Y-direction anti-deformation performance of the seat beam 2. A first reinforcing plate 251 is provided below the central channel 11 of the floor body 1 to improve the anti-deformation performance of the central channel 11.

[0090] Meanwhile, by combining the energy-absorbing structure mentioned above, the deformation pattern of the floor assembly 100 during a side collision can be guided. That is, the energy-absorbing structure at the end of the floor assembly 100 in the Y direction can fully absorb the collision energy, reduce the deformation of the middle region of the floor assembly 100, reduce the intrusion of the floor assembly 100 into the passenger compartment, and protect the battery located under the floor assembly 100, reducing the risk of high-voltage safety problems caused by side collisions and improving the overall driving safety of the vehicle.

[0091] The vehicle according to an embodiment of this application includes the floor assembly 100 described above.
