[0034] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0035] Next, refer to Figures 1-7 to describe the vehicle floor assembly 100 according to the embodiments of the present invention. In addition, the present invention also proposes a vehicle.

[0036] Refer to Figures 1-7 As shown, the vehicle floor assembly 100 according to the embodiments of the present invention includes: at least two cross beams 10, a floor 20, and a floor reinforcement plate 30. The at least two cross beams 10 are spaced apart in the front-rear direction. The floor 20 is disposed between the at least two cross beams 10. A plurality of first protrusions 21 spaced apart in a first direction are provided on the floor 20. The floor reinforcement plate 30 is disposed above the floor 20. A plurality of second protrusions 31 spaced apart in a second direction are provided on the floor reinforcement plate 30. Wherein, the first direction and the second direction are perpendicular to each other, and the first direction and the second direction are the front-rear direction and the left-right direction respectively.

[0037] Specifically, the vehicle floor assembly 100 is provided with two cross beams 10, and a floor 20 is disposed between the two cross beams 10. That is, the two cross beams 10 are respectively located at both ends of the floor 20 in the front-rear direction, and the length of the cross beam 10 is greater than the width of the floor 20. The cross beam 10 increases the stiffness and strength of the entire vehicle structure by connecting and supporting other structural elements at the bottom of the vehicle, such as longitudinal beams and chassis, and can also disperse the load and vibration force borne by the floor 20, improving the stability and safety of the vehicle.

[0038] Among them, a plurality of first protrusions 21 spaced apart in a first direction are provided on the floor 20. That is to say, the plurality of first protrusions 21 are arranged in the front-rear direction of the floor 20 and are spaced apart in the left-right direction of the floor 20. The first protrusions 21 can improve the structural strength of the floor 20, making it more capable of bearing the load of heavy goods or equipment.

[0039] Moreover, a floor reinforcement plate 30 is provided above the floor 20. Multiple second protrusions 31 are provided on the floor reinforcement plate 30 and are spaced apart in the second direction. That is, the multiple second protrusions 31 are arranged in the left-right direction of the floor 20 and are spaced apart in the front-rear direction of the floor 20. The floor reinforcement plate 30 can improve the overall structural strength of the vehicle floor assembly 100. The first protrusion 21 and the second protrusion 31 are perpendicular to each other, which can effectively disperse the force on the vehicle floor assembly 100, make the load evenly distributed, help reduce the local pressure on the floor 20, and avoid fracture or damage caused by strength fatigue of the floor 20.

[0040] Furthermore, after setting the floor reinforcement plate 30 to improve the structural strength of the vehicle floor assembly 100, the structural static stiffness of the vehicle floor assembly 100 is increased by 0.5 mm. The floor 20 can be lifted only 15 mm to accommodate the battery pack 60. Using the floor reinforcement plate 30 to replace the original second and third crossbeams 10 can reduce the weight by 5.325 Kg while ensuring the bearing capacity of the floor 20. In this way, the local lifting height of the floor 20 is reduced, which is convenient for placing goods and makes the appearance more beautiful.

[0041] Among them, both ends of the floor reinforcement plate 30 in the front-rear direction are fixedly connected to the crossbeam 10, and both ends in the left-right direction are fixedly connected to the floor 20. The connection method can be welding.

[0042] Thus, by setting the floor reinforcement plate 30 and using the first protrusion 21 and the second protrusion 31 to be perpendicular to each other, the force distribution on the floor 20 is made uniform, the structural static stiffness of the vehicle floor assembly 100 is increased by 0.5 mm, the floor 20 is prevented from breaking or being damaged, and the floor 20 only needs to be lifted 15 mm to meet the strength fatigue, which is convenient for placing goods and makes the appearance more beautiful.

[0043] Refer to Figures 3-6 As shown, the floor reinforcement plate 30 includes: a first flanging portion 32 and a first protruding portion 33. The first flanging portion 32 is provided at the edge of the first protruding portion 33. The first protruding portion 33 protrudes relative to the first flanging portion 32. Multiple second protrusions 31 are provided on the first protruding portion 33. That is, the first flanging portion 32 is located around the first protruding portion 33. The first flanging portion is used for fixedly connecting to the crossbeam 10 and the floor 20 to fixedly connect the floor reinforcement plate 30 to the floor 20 and the crossbeam 10. Among them, in the up-down direction of the floor reinforcement plate 30, the first protruding portion 33 protrudes upward relative to the first flanging portion 32, and the multiple second protrusions 31 on the first protruding portion 33 also protrude upward relative to the first protruding portion 33, which can enhance the structural strength of the floor reinforcement plate 30.

[0044] Refer to Figure 6As shown, the second protrusion 31 includes: a straight section 34 and two edge sections 35. The two edge sections 35 are disposed at both ends of the straight section 34. The straight section 34 is disposed on the first protrusion portion 33, and the edge section 35 is disposed at the edge of the first protrusion portion 33, and / or the edge section 35 extends to the first flanging portion 32. That is, the second protrusion 31 can be a strip-shaped protrusion. The straight section 34 is located on the first protrusion portion 33, and the two edge sections 35 are respectively located at both ends in the front-rear direction of the straight section 34. That is, the edge section 35 is located at the tapered surface of the first protrusion portion 33, or the edge section 35 can transition along the tapered surface of the first protrusion portion 33 to the first flanging portion 32, which can improve the strength at the edge of the floor reinforcement plate 30 and reduce cracking.

[0045] Referring to Figure 7 As shown, the floor 20 includes: a second flanging portion 22 and a second protrusion portion 23. The second flanging portion 22 is disposed at the edge of the second protrusion portion 23. The second flanging portion 22 is fixedly connected to at least two cross beams 10. The second protrusion portion 23 protrudes relative to the second flanging portion 22, and a plurality of first protrusions 21 are disposed on the second protrusion portion 23. That is, the second flanging portion 22 is located around the second protrusion portion 23. The second flanging portion 22 is used for fixedly connecting to the cross beam 10 and the floor reinforcement plate 30 to fixedly connect the floor 20, the floor reinforcement plate 30, and the cross beam 10. Among them, in the up-down direction of the floor 20, the second protrusion portion 23 protrudes upward relative to the second flanging portion 22, and the plurality of first protrusions 21 on the second protrusion portion 23 protrude downward relative to the second protrusion portion 23, so that a plurality of stepped surfaces are formed on the floor 20, and the structural strength and static stiffness of the floor 20 are better.

[0046] Referring to Figure 1 and Figure 3 As shown, the vehicle floor assembly 100 further includes: a cross beam connecting plate 40 and a connecting plate 50.

Connecting the cross beam connecting plate 40 to the cross beam 10 can form an annular structure on the peripheral side of the floor 20 to make up for the insufficient strength caused by reducing the second and third cross beams. In addition, a connecting plate 50 is disposed at the original positions of the second and third cross beams. One end of the connecting plate 50 is connected to the cross beam connecting plate 40 and the other end is fixedly connected to the floor 20. The connecting plate 50 is provided with suspension mounting points, which can be used to replace the second and third cross beams to install, fix, or hang various components, devices, or systems.
