Technical Field

[0001] The present invention relates to the technical field of automobiles, and particularly relates to a floor assembly and a vehicle. Background Art

[0002] As one of the commonly used means of transportation for people, due to its relatively high driving speed, the safety of automobiles has attracted much attention. When an automobile is driving, if it is collided, especially when the automobile is obliquely collided, the impact force is easily transmitted into the passenger compartment, thus causing harm to the passengers. Therefore, how to improve the safety of an automobile when it is obliquely collided has become a technical problem to be solved. Summary of the Invention

[0003] The present invention provides a floor assembly and a vehicle.

[0004] The floor assembly according to the embodiment of the present application is used for a vehicle, and the floor assembly includes:

[0005] A front floor, the front floor includes a central passage, cross beams and inclined beams both connected to the central passage, the front floor has a front end portion and a rear end portion, the front end portion and the rear end portion are arranged along the length direction of the vehicle, the inclined beam is located in front of the cross beam, and the inclined beam is inclined relative to the central passage.

[0006] In the floor assembly according to the embodiment of the present application, the inclined beam can transmit the impact force when the vehicle head is obliquely collided, so as to reduce the concentration of the impact force, thereby reducing the damage suffered by the vehicle.

[0007] In some embodiments, the number of the cross beams is multiple, and the multiple cross beams are arranged on both sides of the width of the central passage. The number of the cross beams on the same side of the central passage is at least three, and at least three cross beams are arranged at intervals along the length direction of the central passage. In this way, the guide rail has more support points, so that the guide rail is not easily deformed, and the stability of the use of the guide rail is improved. In addition, the multiple cross beams enable the vehicle to have more conduction paths for the impact force in the case of a side collision, thereby reducing the probability of the vehicle being damaged, and further improving the safety of the vehicle.

[0008] In some embodiments, the front floor includes a force-bearing beam connected to the end of the inclined beam away from the central passage. The force-bearing beam includes a first section and a second section connected to the first section. The first section extends along the length direction of the vehicle, and the second section is inclined relative to the first section, and the second section is connected to the inclined beam. In this way, the first section of the force-bearing beam extends along the length direction of the vehicle, so that the force-bearing beam can transmit and disperse the impact force to various positions of the front floor when the vehicle has a small offset collision, thereby reducing the probability of damage to the vehicle due to the concentration of the impact force.

[0009] In some embodiments, a concave portion is formed on one side of the first section facing the interior of the vehicle along the width direction of the vehicle, and the concave portion is concave toward the exterior of the vehicle. In this way, when the front of the vehicle is hit, the concave portion can guide part of the impact force to the exterior of the vehicle, thereby reducing the impact force transmitted to the passenger compartment of the vehicle, thereby improving the safety of the vehicle occupants.

[0010] In some embodiments, the stress beam includes a hollow surrounding wall and a partition, the partition is arranged in the hollow surrounding wall and partitions the internal space of the hollow surrounding wall in the extension direction of the stress beam, and the hollow surrounding wall forms the first section and the second section. In this way, the partition can isolate the shock wave in the stress beam when the front of the vehicle is hit, which can not only reduce the impact force transmitted to the interior of the vehicle, but also reduce the generation of noise.

[0011] In some embodiments, the floor assembly further includes a guide rail, which is disposed on the crossbeam and extends from the front end to the rear end, and is used to install a seat. Thus, the guide rail extends from the front end of the front floor to the rear end of the front floor, so that the seat has a larger range of movement on the guide rail, thereby expanding the application scenarios of the seat.

[0012] In some embodiments, the floor assembly includes a driving device disposed on the guide rail, the driving device is used to drive the seat to slide along the guide rail, the number of the guide rails is multiple, and the multiple guide rails are arranged at intervals along the width direction of the vehicle, and the number of the driving devices on the same guide rail is multiple, and the multiple driving devices are arranged at intervals along the length direction of the guide rail. In this way, the driving device can drive the seat to move by electric drive, thereby realizing the automation of seat movement. In addition, multiple guide rails allow multiple seats to be arranged in the width direction of the vehicle, meeting the user's demand for a vehicle with multiple seats.

[0013] In certain embodiments, the floor assembly includes a carpet, the carpet is disposed on the front floor and covers the central channel and the cross beam, the guide rail is exposed through the carpet, the upper surface of the carpet is flat, and the surface profile is ±1.5 mm; and / or,

[0014] The height difference between the top surface of the guide rail and the upper surface of the carpet is within a range of ±3 mm. In this way, the entire surface of the passenger compartment of the vehicle is relatively flat, which is conducive to the movement of the seat and improves the riding comfort of the occupants.

[0015] In some embodiments, the carpet includes a support layer and a surface layer stacked with the support layer, wherein the surface layer is located on a side of the support layer away from the cross beam. Thus, the top surface of the guide rail and the upper surface of the carpet together form a relatively flat plane, so that the entire surface of the passenger compartment of the vehicle is relatively flat, which is conducive to the movement of the seat and improves the riding comfort of the passengers.

[0016] In certain embodiments, the floor assembly includes a dash panel and a rear floor, the dash panel is connected to the front end of the front floor, the rear floor is connected to the rear end of the front floor, and the guide rail extends to the connection between the rear floor and the front floor. In this way, the dash panel, the rear floor and the front floor can together enclose a passenger compartment space, and the guide rail extends to the connection between the rear floor and the front floor, thereby increasing the movement range of the seat.

[0037] Please refer to Figure 1 , the present application discloses a vehicle 200, and the vehicle 200 includes a floor assembly 100. The vehicle 200 is, for example, a vehicle 200 powered by a power source such as a battery.

[0038] Please refer to Figures 2 - 4 , the floor assembly 100 of the embodiment of the present application is for the vehicle 200. The floor assembly 100 includes a front floor 10. The front floor 10 includes a central channel 11, cross beams 12 and inclined beams 15 both connected to the central channel 11. The front floor 10 has a front end portion 13 and a rear end portion 14, and the front end portion 13 and the rear end portion 14 are arranged along the length direction of the vehicle 200.

[0039] In the floor assembly 100 of the embodiment of the present application, the inclined beam 15 can transmit the impact force when the front of the vehicle 200 is subjected to an inclined collision, so as to reduce the concentration of the impact force, thereby reducing the damage suffered by the vehicle 200. Specifically, the floor assembly 100 is the main structure of the vehicle 200, and the front floor 10 is a combination of the middle part and the front part of the floor assembly 100. The front floor 10 generally has a relatively flat structure. The front floor 10 can be formed by manufacturing with the same sheet material. The central channel 11 is a structure located at the central position in the width direction of the front floor 10, and the central channel 11 can be used to install components such as wire tubes. The length of the central channel 11 extends along the length direction of the vehicle 200. The central channel 11 can be formed by a pressing process. For example, the central channel 11 is formed by pressing a sheet material so that the sheet material bulges upward to form the central channel 11.

[0040] The cross beam 12 is located on one side in the width direction of the central channel 11. The length direction of the cross beam 12 can be perpendicular to the length direction of the central channel 11, or rather, the cross beam 12 extends along the width direction of the vehicle 200. The cross beam 12 can be welded to the central channel 11, so that the connection between the cross beam 12 and the central channel 11 is more firm.

[0041] It should be noted that in the embodiment of the present application, the directions referred to by "front" and "rear" are referenced with the orientation of the vehicle 200. The front of the vehicle 200 is the front, and the rear of the vehicle 200 is the rear. Therefore, the front end portion 13 of the front floor 10 is the most front part of the front floor 10, and the rear end portion 14 of the front floor 10 is the most rear part of the front floor 10.

[0042] Exemplarily, the angle at which the inclined beam 15 is inclined relative to the central channel 11 is 45 degrees. In the embodiment of the present application, the number of inclined beams 15 is two, one on each of the left and right sides of the central channel 11. The two inclined beams 15 are symmetrically arranged with respect to the central channel 11. The inclined beam 15 can be integrally formed with the central channel 11 by welding, stamping, etc.

[0043] In the embodiment of the present application, the front of the vehicle 200 being subjected to an inclined collision means that when the front of the vehicle 200 is collided, the main direction of the collision force is inclined relative to the length or width of the vehicle 200.

[0044] Please refer to Figures 2 - 3 , in some embodiments, the floor assembly 100 further includes a guide rail 20. The guide rail 20 is arranged on the cross beam 12. The guide rail 20 extends from the front end portion 13 to the rear end portion 14, and the guide rail 20 is used for installing a seat.

[0045] In this way, the guide rail 20 extends from the front end portion 13 to the rear end portion 14 of the front floor 10, so that the moving range of the seat on the guide rail 20 is larger, thereby expanding the application scenarios of the seat.

[0046] In the embodiments of the present application, the guide rail 20 is generally a long straight guide rail. The length direction of the guide rail 20 may be the same as the length direction of the front floor 10. The guide rail 20 extends from the front end portion 13 to the rear end portion 14, or rather, the length of the guide rail 20 is almost equal to the length of the front floor 10. For example, the length ratio of the guide rail 20 to the front floor 10 may be greater than 4 / 5. Therefore, after the seat is installed on the guide rail 20, the range of the forward and backward movement of the seat is large, expanding the application scenarios of the seat. For example, when the seats are arranged in two rows, the front row seats can move forward and the rear row seats can move backward, making the space between the front row seats and the rear row seats large, facilitating the occupants to sit directly on the floor.

[0047] Please refer to Figure 3 and Figure 4 , in some embodiments, the number of the cross beams 12 is multiple. The multiple cross beams 12 are arranged on both sides of the width of the central passage 11. The number of the cross beams 12 on the same side of the central passage 11 is at least three, and at least three cross beams 12 are arranged at intervals along the length direction of the central passage 11.

[0048] Since the guide rail 20 is relatively long, therefore, the number of the cross beams 12 on the same side of the central passage 11 is at least three, so that the guide rail 20 has more support points, making the guide rail 20 not easily deformed and improving the stability of the use of the guide rail 20. In addition, the multiple cross beams 12 enable the vehicle 200 to have more conduction paths for the impact force in the case of a side collision, thereby reducing the probability of the vehicle 200 being damaged and further improving the safety of the vehicle 200.

[0049] As Figure 4 in the example, the total number of the cross beams 12 is 8, the number of the cross beams 12 on the same side of the central passage 11 is 4, and the guide rail 20 can be supported on 4 central passages 11.

[0050] As Figure 4 in the example, the total number of the cross beams 12 is 8, and the total number of the inclined beams 15 is 2, making the structure formed by the central passage 11, the cross beams 12 and the inclined beams 15 similar to the shape of a crab. This bionic structure enables the front floor 10 to be well stressed, which is beneficial to the transmission of the impact force, and further reduces the damage to the floor assembly 100 and the vehicle 200.

[0051] As Figure 2 shown by the dotted arrow in, when the front floor 10 is impacted, the impact force can spread along the cross beams 12 and the inclined beams 15, thereby reducing the risk of the front floor 10 being damaged due to stress concentration.

[0052] In some embodiments, multiple crossbeams 12 located on the same side of the central channel 11 may be arranged at uniform intervals or non-uniform intervals, and the present application does not limit the arrangement intervals of the multiple crossbeams 12.

[0053] Please refer to Figure 4 , in certain embodiments, multiple crossbeams 12 are symmetrically arranged on both sides of the width of the central channel 11, which makes it easier to arrange the crossbeams 12 and enables the impact forces received on the left and right sides of the front floor 10 to be transmitted to each other, facilitating the diffusion of the impact force. For example, the left crossbeam 12 and the right crossbeam 12 are symmetrically arranged. When an impact force is received on the left side of the vehicle 200, the impact force can be transmitted successively through the left crossbeam 12, the central channel 11, and the right crossbeam 12, enabling the impact force to spread quickly and reducing the probability of damage to the vehicle 200.

[0054] Please refer to Figure 4 , in certain embodiments, the front floor 10 includes a load-bearing beam 16 connected to one end of the inclined beam 15 away from the central channel 11. The load-bearing beam 16 includes a first section 161 and a second section 162 connected to the first section 161. The first section 161 extends along the length direction of the vehicle 200, and the second section 162 is inclined relative to the first section 161 and is connected to the inclined beam 15.

[0055] In this way, the first section 161 of the load-bearing beam 16 extends along the length direction of the vehicle 200, enabling the load-bearing beam 16 to transmit the impact force through the inclined beam 15 and spread it to various positions of the front floor 10 during a small-offset collision of the vehicle 200, thereby reducing the probability of damage to the vehicle 200 due to concentrated impact force. In addition, the second section 162 of the load-bearing beam 16 can transmit the force received from the rear side of the front of the vehicle 200, reducing the probability of damage to the vehicle 200.

[0056] Specifically, both the first section 161 and the second section 162 of the load-bearing beam 16 are strip-shaped, and the first section 161 and the second section 162 of the load-bearing beam 16 are of an integral structure, making the load-bearing beam 16 bent. The end of the second section 162 away from the first section 161 can be flush with the end of the crossbeam 12 in the length direction of the vehicle 200, enabling the load-bearing beam 16 and the crossbeam 12 to transmit the impact force generated during a side collision of the vehicle 200 simultaneously.

[0057] Please refer to Figures 4 - 6 , in certain embodiments, along the width direction of the vehicle 200, a recess 1611 is formed on the side of the first section 161 facing the interior of the vehicle 200, and the recess 1611 is recessed towards the outside of the vehicle 200. In this way, when the front of the vehicle 200 is collided, the recess 1611 can guide part of the impact force towards the outside of the vehicle 200, reducing the impact force transmitted into the passenger compartment of the vehicle 200, and thus improving the safety of the passengers in the vehicle 200.

[0058] Specifically, the concave portion 1611 may be in the shape of a circular arc or an obtuse angle, and the present application does not limit the specific shape of the concave portion 1611. In addition, the middle position of the first section 161 is generally connected to other components of the vehicle 200, so the concave portion 1611 may be formed in the middle position of the length of the first section 161 to transmit the impact force to other components of the vehicle 200.

[0059] See also Figures 4 - 6 In some embodiments, the stress beam 16 includes a hollow surrounding wall 163 and a partition 164. The partition 164 is disposed in the hollow surrounding wall 163 and partitions the inner space of the hollow surrounding wall 163 in the extension direction of the stress beam 16. The hollow surrounding wall 163 forms a first section 161 and a second section 162. In this way, the partition 164 can isolate the shock wave in the stress beam 16 when the front of the vehicle 200 is hit, which can not only reduce the impact force transmitted to the interior of the vehicle, but also reduce the generation of noise.

[0060] See also Figure 6 In some embodiments, the stress beam 16 further includes a reinforcing plate 165, which is disposed in the hollow surrounding wall 163 and connected to the hollow surrounding wall 163. In this way, the reinforcing plate 165 can strengthen the strength of the stress beam 16, so that the stress beam 16 is not prone to collapse and other defects when subjected to impact force, thereby effectively transmitting and dispersing the impact force.

[0061] See also Figure 3 and Figure 7 In some embodiments, the floor assembly 100 includes a driving device 30 disposed on the guide rail 20, the driving device 30 is used to drive the seat to slide along the guide rail 20, the number of the guide rails 20 is multiple, and the multiple guide rails 20 are arranged at intervals along the width direction of the vehicle 200, and the number of the driving devices 30 located on the same guide rail 20 is multiple, and the multiple driving devices 30 are arranged at intervals along the length direction of the guide rail 20.

[0062] In this way, the driving device 30 can drive the seat to move by an electric drive, thereby realizing the automation of the seat movement. In addition, the plurality of guide rails 20 enable a plurality of seats to be arranged in the width direction of the vehicle 200, thereby satisfying the user's vehicle use demand for multiple seats.

[0063] Specifically, in the embodiment of the present application, the number of guide rails 20 is 4, two guide rails 20 are respectively arranged on both sides of the central channel 11, and a driving device 30 is arranged on the two guide rails 20 on the same side of the central channel 11, thereby improving the stability of the driving device 30.

[0064] It should be noted that the driving devices 30 and the seats can be arranged one by one, or in other words, one driving device 30 can drive one seat to move. When multiple seats in the same row are integrated, the multiple driving devices 30 driving the seats in the same row can move synchronously, so that the multiple seats move synchronously, reducing the risk of interference between the multiple driving devices 30.

[0065] See also Figures 7 - 9 In some embodiments, the floor assembly 100 includes a carpet 40, which is disposed on the front floor 10 and covers the central channel 11 and the cross beam 12, the guide rail 20 is exposed through the carpet 40, and the upper surface 401 of the carpet 40 is flat and has a surface contour of ±1.5 mm.

[0066] Since the bottom of the front floor 10 is used to accommodate fewer automotive parts, the upward bulge height of the central channel 11 and the cross beam 12 in the front floor 10 is relatively small. After the carpet 40 is laid on the front floor 10, the structure of the carpet 40 can complement the structure of the front floor 10, so that the upper surface 401 of the carpet 40 is flat and the surface contour is ±1.5mm, thereby making the entire surface of the passenger compartment of the vehicle 200 relatively flat, which is conducive to the movement of the seats and improving the riding comfort of the occupants.

[0067] In some embodiments, the height difference between the top surface 201 of the guide rail 20 and the upper surface 401 of the carpet 40 is within a range of ±3 mm. For example, the height difference between the top surface 201 of the guide rail 20 and the upper surface 401 of the carpet 40 is -3 mm, -1 mm, 0 mm, 3 mm, etc. In this way, the top surface 201 of the guide rail 20 and the upper surface 401 of the carpet 40 form a relatively flat plane, so that the entire surface of the passenger compartment of the vehicle 200 is relatively flat, which is conducive to the movement of the seat and improves the comfort of the passengers.

[0068] It should be noted that the top surface 201 of the guide rail 20 and the upper surface 401 of the carpet 40 are both surfaces facing upward when the vehicle 200 is normally in operation.

[0069] like Figure 8 As shown, in some embodiments, the carpet 40 includes a support layer 42 and a surface layer 43 stacked with the support layer 42, and the surface layer 43 is located on the side of the support layer 42 away from the cross beam 12. In this way, the support layer 42 can provide support for the surface layer 43, so that the shape of the surface layer 43 is stable. The surface layer 43 forms the upper surface 401 of the carpet 40, which is a layer structure in direct contact with the passenger, and the surface layer 43 can be made of a relatively soft material. For example, the surface layer 43 can be made of leather, imitation leather and other materials. The support layer 42 can be made of a relatively hard material such as plastic that is easy to shape, so as to provide support for the surface layer 43.

[0070] See alsoFigure 8 , in some embodiments, the floor assembly 100 includes a filler 50 disposed between the front floor 10 and the carpet 40. In this way, the filler 50 can fill the uneven spaces formed by structures such as the crossbeam 12 and the central tunnel 11 to form a relatively flat surface, making it easier to lay the carpet 40. Specifically, the material of the filler 50 is, for example, foam plastic, which makes the filler 50 easy to mold and lightweight, facilitating the installation of the filler 50.

[0071] Please refer to Figure 8 , in some embodiments, the floor assembly 100 includes electrical components 60 disposed between the front floor 10 and the carpet 40. In this way, the installation of the electrical components 60 can make full use of the space between the front floor 10 and the carpet 40, making the structure of the vehicle 200 more compact.

[0072] Please refer to Figure 2 , Figure 3 and Figure 7 , in some embodiments, the floor assembly 100 includes a front bulkhead 70 and a rear floor 80. The front bulkhead 70 is connected to the front end of the front floor 10, and the rear floor 80 is connected to the rear end portion 14 of the front floor 10. The guide rail 20 extends to the connection between the rear floor 80 and the front floor 10. In this way, the front bulkhead 70, the rear floor 80 and the front floor 10 can jointly enclose the passenger compartment space, and the guide rail 20 extends to the connection between the rear floor 80 and the front floor 10, so that the moving range of the seat is larger.

[0073] Specifically, the front bulkhead 70 and the front floor 10 can be formed as an integral structure by casting. For example, the front bulkhead 70 and the front floor 10 can be cast from steel. The rear floor 80 is generally an irregular structure, and the rear floor 80 and the front floor 10 can be fixed together by welding or other means. The rear floor 80 can be made of aluminum alloy material.

[0074] Please refer to Figure 8 and Figure 9 , in some embodiments, the vehicle 200 further includes a power battery 210, and the power battery 210 is disposed on the bottom surface of the front floor 10. In this way, the power battery 210 can provide power for the vehicle 200. In addition, by disposing the power battery 210 on the bottom surface of the front floor 10, the center of gravity of the vehicle 200 can tend to the center of the vehicle 200, making the vehicle 200 more stable during driving.
