With the development of society, people pay more and more attention to the safety problem of automobiles, and are required to bear strict head-on collision, so that the safety of drivers and passengers is ensured. In the new vehicle collision test NCAP (New Car Association program) evaluation, the rigidity of the passenger compartment has a direct relation with the injury of passengers, the rigidity of the passenger compartment is high, the deformation of the compartment body in the collision is small, the living space of the passengers is ensured, and the injury of the passengers is correspondingly reduced.
Meanwhile, people pay more and more attention to the problem of space utilization rate in the automobile and the comfort of passengers, and under the condition of meeting the safety problem of frontal collision of the automobile, the larger the space in the automobile is, the better the space in the automobile is, and the leg space and the footstep space of the passengers in the back row are required to be large enough, so that the comfort of the passengers in the back row is ensured. If the passageway anterior segment is not strong enough in the preceding floor, can lead to just bumping in-process passenger injury, if well passageway afterbody space is not enough, two rows of passenger's feet can't be straightened, lead to passenger's comfort level to feel extremely poor.
In view of this, the present invention provides a vehicle body front floor middle tunnel structure 1000 and a vehicle, and since the main point of the present invention is directed to the vehicle body front floor middle tunnel structure 1000, other parts of the vehicle will not be described in detail herein. In the drawings of the present specification, fig. 1 is a schematic three-dimensional structure diagram of a tunnel structure 1000 in a vehicle body front floor according to an embodiment of the present invention; fig. 2 is a schematic perspective view of the connection plate 300 in fig. 1; FIG. 3 is a schematic, diagrammatic perspective view of the channel backing plate 200 of FIG. 1; fig. 4 is a schematic cross-sectional view of the tunnel structure in the vehicle body front floor of fig. 1.
Referring to fig. 1, the present invention provides a vehicle body front floor middle channel structure 1000, which includes a bottom plate for enclosing with two sides of a vehicle body together to form a middle channel, wherein the bottom plate includes a middle channel front plate 100, a middle channel rear plate 200, a connecting plate 300 and a vehicle body rear floor 400, which are sequentially connected from front to rear: wherein, the middle channel back plate 200 is arranged below the middle channel front plate 100; the connecting plate 300 is arranged between the middle channel front plate 100 and the middle channel rear plate 200, the upper end of the connecting plate 300 is connected with the rear end of the middle channel front plate 100, and the lower end of the connecting plate 300 is connected with the front end of the middle channel rear plate 200; the front end of the rear floor 400 is connected to the rear end of the center tunnel rear panel 200. At least part of the middle channel front plate 100 is gradually arranged downwards in an inclined manner from front to back, so that the weight of the middle channel front plate 100 is greatly reduced compared with the existing structure, and the purposes of reducing the weight and the cost of a body-in-white are achieved; meanwhile, the space in the vehicle is effectively released, and the step space comfort of the two rows of passengers in the tail area of the vehicle is effectively ensured. In this embodiment, the front plate 100 of the center tunnel has a high front and a low rear, and the cross section at the front end is the largest, so as to ensure effective transmission of the frontal collision force, and the height is gradually reduced toward the rear, thereby ensuring effective utilization of the space in the vehicle.
Further, in order to ensure that the position of the center tunnel rear panel 200 in the vehicle height direction is adjustable, in the technical solution provided by the present invention, the connecting plate 300 has a first welding section 310 welded to the center tunnel rear panel 200, the connecting plate 300 extends downward from the first welding section 310 to form a first welding extension 320, and the first welding extension 320 is used for being cut to a set length and then welded to the center tunnel rear panel 200 together with the first welding section 310. It should be noted that the first welding extension 320 may be cut away without affecting the specific function of the connection plate 300. The installation height of the middle channel rear plate 200 can be raised by cutting off the first welding extension section 320, the installation requirements of different vehicle types can be met, the development of a mold is not required, and the working efficiency is greatly improved.
Referring to fig. 1-4, the upper end of the connecting plate 300 is bent forward to form a first flange 330, and the first flange 330 is used to connect with the rear end of the front center channel plate 100. The included angle formed by the first turned-over edge 330 and the connecting plate 300 is greater than 80 degrees and less than 90 degrees, in this embodiment, the included angle is set to 90 degrees, and the stability is high.
When the axle base of the whole vehicle changes, the axle base of the whole vehicle can be lengthened and shortened through the change of the middle channel rear plate 200 in the length direction of the vehicle body. In the technical scheme provided by the invention, similar to the previous scheme, the rear end of the center tunnel rear plate 200 is provided with a second welding section 210 welded with the vehicle body rear floor 400, the center tunnel rear plate 200 extends backwards from the second welding section 210 to form a second welding extension section 220, and the second welding extension section 220 is used for being cut to a set length and then is welded to the vehicle body rear floor 400 together with the second welding section 210. Through carrying out effectual excision to second welding extension 220, can satisfy the requirement of different motorcycle types wheel bases, and need not to carry out the development of mould, greatly jumped work efficiency. Meanwhile, the longer middle channel rear plate 200 can meet the requirement of comfortable arrangement of footsteps of two rows of passengers, and the uncomfortable phenomenon that the feet are not stretched directly is avoided.
Further, a convex hull is convexly arranged on the middle part of the middle channel back plate 200 upwards, so that an avoiding space is formed at the lower end of the middle channel back plate 200 corresponding to the convex hull. To avoid local strength and local mode problems, the convex hull has a protrusion height H relative to the center channel backplate 200 of 18-22 mm. Specifically, the middle channel back plate 200 includes a middle channel back plate body 250, a middle plate 230 disposed above the middle channel back plate body 250, and two side plates 240 connected to opposite sides of the middle plate 230 and respectively connected to the middle channel back plate body 250, wherein the two side plates 240 and the middle plate 230 together enclose to form a convex hull. In addition, one end of the middle plate 230 near the connecting plate 300 is bent upwards to form a second flange 231, and the second flange 231 is used for being welded with the lower end of the connecting plate 300.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
