[0038] See also Figure 8 The central channel cover plate 30 includes two connecting sections along its width direction, that is, along the Y-axis direction, and a first positioning section 31 between the two connecting sections. The two connecting sections are a first connecting section 32 and a second connecting section 33. The first connecting section 32 is connected to the first positioning section 31 at an angle. One side of the first connecting section 32 is connected to the first positioning section 31. The other side of the first connecting section 32 is bent relative to the first positioning section 31 along the negative direction of the Z axis and connected to the side of the first bending section 232 away from the floor 200. The second connecting section 33 is connected to the first positioning section 31 at an angle. One side of the second connecting section 33 is connected to the first positioning section 31.

At least a portion of the first positioning section 31 is stacked and connected to the first middle section 231. At least a portion of the first positioning section 31 is opposite to the notch of the first groove 207.
[0039] For further information, see Figure 6The first middle section 231 includes a concave section 2311, a first convex section 2312, and a second convex section 2313. The first convex section 2312 is connected to the first bending section 232 at an angle, the first convex section 2312 is connected to the concave section 2311 at an angle, the first bending section 232 and the concave section 2311 are both bent relative to the first convex section 2312 along the negative direction of the Z axis, one side of the first convex section 2312 is connected to the first bending section 232, and the other side of the first convex section 2312 is connected to the concave section 2311. The second convex section 2313 is connected to the second bending section 233 at an angle, the second convex section 2313 is connected to the concave section 2311 at an angle, the second bending section 233 and the concave section 2311 are both bent relative to the second convex section 2313 along the negative direction of the Z axis, one side of the second convex section 2313 is connected to the second bending section 233, and the other side of the second convex section 2313 is connected to the concave section 2311. The cross section of the concave section 2311 along the width direction of the central channel cover plate 30 is quasi-U-shaped. Along the width direction of the central channel reinforcement plate 20, the first bending section 232, the concave section 2311 and the second bending section 233 are arranged in sequence.
[0040] The aforementioned U-shape means that the cross-section of the concave section 2311 along the width direction of the central channel cover 30 is similar to a U-shape, but is not a standard U-shape, for example, the bottom surface of the concave section 2311 is flush with respect to the Y-axis direction.
[0041] The first positioning section 31 includes a recessed portion 311, which is recessed along the negative direction of the Z axis to form a groove. The groove depth of the recessed portion 311 along the Z axis is greater than the groove depth of the second groove 313 along the Z axis. The recessed portion 311 is received in the first groove 207, so that the central channel cover plate 30 will not slide relative to the central channel reinforcement plate 20 along the Y axis, so that the central channel cover plate 30 and the central channel reinforcement plate 20 are assembled more firmly.
[0042] The cross-section of the central channel reinforcement plate 20 along the width direction is M-shaped, so that the central channel reinforcement plate 20 has higher strength and rigidity, can bear larger loads and moments, and is very effective when the large-span passenger compartment is subjected to the huge impact force of the front compartment; the central channel reinforcement plate 20 has better bending resistance, can effectively disperse and withstand the bending force caused by external loads, and improve the stability and safety of the passenger compartment; the central channel reinforcement plate 20 can provide a larger effective force-bearing cross-sectional area, while reducing the dead weight of the structure, which is beneficial to the optimal utilization of the passenger compartment space, and is beneficial to reducing the intrusion of the front seats, while improving the economy of the vehicle and ensuring the comfort of the passengers.
[0043] The above-mentioned M-shaped section means that the cross section of the central channel reinforcement plate 20 along the width direction is similar to the M-shape, but it is not a standard M-shape. For example, the first protrusion 2312 and the second protrusion 2313 of the central channel reinforcement plate 20 are flush with each other relative to the Y-axis direction.
[0044] In the connection method of the central channel reinforcement plate 20 and the central channel cover plate 30, the connection method of the central channel reinforcement plate 20 and the central channel cover plate 30 may include but is not limited to a combination of one or more of welding, clamping, bonding, heat fusion, threaded connection, etc. Exemplarily, the central channel cover plate 30 is stacked on the central channel reinforcement plate 20 through welding point connection. The first middle section 231, the first bending section 232 and the second bending section 233 of the central channel reinforcement plate 20 are each provided with a plurality of welding points, and the plurality of welding points are spaced apart along the length direction of the central channel reinforcement plate 20. The first positioning section 31, the first connecting section 32 and the second connecting section 33 of the central channel cover plate 30 are each provided with a plurality of welding points, and the plurality of welding points are spaced apart along the length direction of the central channel cover plate 30. The welding points of the first middle section 231 correspond one-to-one with the welding points of the first positioning section 31 , the welding points of the first bending section 232 correspond one-to-one with the welding points of the first connecting section 32 , and the welding points of the second bending section 233 correspond one-to-one with the welding points of the second connecting section 33 , which facilitates the welding of the central channel reinforcement plate 20 and the central channel cover plate 30 .
[0045] In the present application, the central channel reinforcement plate 20 is connected to the floor 200, and the central channel cover plate 30 is stacked and connected to the central channel reinforcement plate 20, which increases the transmission and dispersion of the impact force and can better transmit the impact force between the various parts. For example, the impact force of the central channel reinforcement plate 20 can be dispersed to the central channel cover plate 30 and the floor 200, thereby dispersing the impact force on the vehicle body frame, and improving the transmission efficiency of the impact force of the whole vehicle. The central channel cover plate 30 is stacked and connected to the central channel reinforcement plate 20, and the first body 23 of the central channel reinforcement plate 20 and the central channel cover plate 30 are both arranged relative to the floor 200 along the Z axis; the cross-sectional thickness of the central channel reinforcement plate 20 and the central channel cover plate 30 relative to the floor 200 along the Z axis direction increases, thereby improving the bending strength of the central channel assembly 100, the vehicle body has a strong anti-frontal collision ability, and the vehicle has high safety performance. The central channel cover 30 and the floor 200 enclose a first space 206, and the fourth surface 302 of the central channel cover 30 and the notch of the first groove 207 form a first cavity 305. The first space 206 and the first cavity 305 can provide a certain energy absorption space to protect the safety of the occupants in the passenger compartment.

A reinforcement groove is provided on the fifth surface of the front crossbeam 40 for a seat along the positive direction of the Z-axis, and the notch of the reinforcement groove faces the floor 200. The fifth surface of the front crossbeam 40 for a seat and the floor 200 enclose a third cavity 403.
[0047] Further, the front cross beam 40 of the seat includes a second middle section 41, a third bending section 42 and a fourth bending section 43, and the third bending section 42, the second middle section 41 and the fourth bending section 43 are sequentially connected along the length direction of the central channel assembly 100. The third bending section 42 is connected to the second middle section 41 at an angle, one side of the third bending section 42 is connected to the second middle section 41, and the other side of the third bending section 42 is bent along the negative direction of the Z axis relative to the second middle section 41 and connected to the floor 200. The fourth bending section 43 is connected to the second middle section 41 at an angle, one side of the fourth bending section 43 is connected to the second middle section 41, and the other side of the fourth bending section 43 is bent along the negative direction of the Z axis relative to the second middle section 41 and connected to the floor 200. The third bending section 42, the second middle section 41, the fourth bending section 43 and the floor 200 enclose a third cavity 403.
[0048] In the connection method of the central channel reinforcement plate 20, the central channel cover plate 30 and the front cross beam 40 of the seat, the central channel cover plate 30, the central channel reinforcement plate 20 and the front cross beam 40 of the seat are sequentially connected along the thickness direction of the central channel assembly 100, including but not limited to one or more combined connections such as welding, clamping, bonding, thermal fusion, and threaded connection. For example, in combination Figure 6 The central channel reinforcement plate 20 includes two first connecting pieces 25, one of which is connected to the first protruding section 2312, and the other first connecting piece 25 is connected to the second protruding section 2313. The first connecting piece 25 extends along the positive direction of the X-axis relative to the first protruding section 2312, and the first connecting piece 25 extends along the positive direction of the X-axis relative to the second protruding section 2313. The central channel reinforcement plate 20 also includes two second connecting pieces 26, one of which is connected to the first bending section 232 at an angle, one side of the second connecting piece 26 is connected to the first bending section 232, and the other side of the second connecting piece 26 is bent along the negative direction of the Y-axis relative to the first bending section 232. The other second connecting piece 26 is connected to the second bending section 233 at an angle, one side of the second connecting piece 26 is connected to the second bending section 233, and the other side of the second connecting piece 26 is bent along the positive direction of the Y-axis relative to the second bending section 233. Combined with Figure 7The central channel cover plate 30 includes a third connecting piece 35, which is connected to the first positioning section 31, and the third connecting piece 35 extends along the positive direction of the X axis relative to the first positioning section 31. Figure 1 and Figure 2 Along the thickness direction of the central channel assembly 100, the second middle section 41 of the seat front cross beam 40, the first connecting piece 25 and the third connecting piece 35 are connected in sequence by welds, and the two second connecting pieces 26 are connected to the third bending section 42 by welds, so that the central channel reinforcement plate 20 and the central channel cover plate 30 are connected to the seat front cross beam 40.
[0049] In this embodiment, the central channel reinforcement plate 20, the central channel cover plate 30, the seat front cross beam 40 and the floor 200 are connected together, which increases the force transmission and dispersion effect and can better transmit the collision force between the various parts. For example, the collision force on the seat front cross beam 40 can be dispersed to the central channel reinforcement plate 20, the central channel cover plate 30 and the floor 200, and then the collision force is dispersed on the vehicle body frame, thereby improving the transmission efficiency of the collision force of the entire vehicle.
