Because all parts on the vehicle floor structure do not need to be replaced, the development range is greatly reduced, the development period of the vehicle is shortened, and the cost is reduced.
The following provides a more detailed description of the structure and operation of each constituent unit of the wheel base changing member provided in the present embodiment.
In some embodiments of the present application, the body 1 may be a rear section of a body of an original front floor assembly 6, or may be a front section of a body of an original middle floor assembly 7.
In some embodiments of the present application, as shown in fig. 1, the end surface of the first end of the rear section 3 of the centre channel sill extends from the first side of the body 1 or is set back relative to the first side of the body 1. The two middle channel boundary beam rear sections 3 are respectively a first middle channel boundary beam rear section 31 and a second middle channel boundary beam rear section 32.

In some embodiments of the present application, the end faces of the first ends of the two front floor stringer back sections 4 protrude from the first side of the body 1 or are set back with respect to the first side of the body 1. The two front floor stringer rear sections 4 are a first front floor stringer rear section 41 and a second front floor stringer rear section 42, respectively.
A seventh mounting hole 401 is formed in the first end of the first front floor longitudinal beam rear section 41, and an eighth mounting hole 402 is formed in the first end of the second front floor longitudinal beam rear section 42; the seventh mounting hole 401 and the eighth mounting hole 402 are adapted to be fixed together with a corresponding mounting hole on the body of the vehicle front floor assembly 6 by a fastener, respectively.
It should be noted that the positional relationship between the first end of the first center tunnel side rail rear section 31, the first end of the second center tunnel side rail rear section 32, the first end of the first front floor side rail rear section 41, and the first end of the second front floor side rail rear section 42 and the first side of the body 1 is determined by the installation sequence of the parts in the vehicle floor assembly, and specifically, the following is true:
the first installation sequence is: the middle floor assembly 7 is installed first, then the wheel base changing member is installed, and finally the front floor assembly 6 is installed. At this time, the first end of the first center tunnel side sill rear section 31, the first end of the second center tunnel side sill rear section 32, the first end of the first front floor side sill rear section 41 and the first end of the second front floor side sill rear section 42 all extend from the first side of the body 1, and the two vehicle center tunnel side sill front sections and the two vehicle floor side sill front sections are all retracted with respect to the side of the body of the front floor assembly 6 near the wheel base changing member.

At this time, the body of the vehicle front floor assembly 6 overlaps the first side of the body 1, and the body 1 is located on the side close to the ground, and the above two bodies are welded together.
The second installation sequence is: the front floor assembly 6 is installed first, then the wheel base changing member is installed, and finally the middle floor assembly 7 is installed. At this time, the first end of the first center tunnel side rail rear section 31, the first end of the second center tunnel side rail rear section 32, the first end of the first front floor side rail rear section 41, and the first end of the second front floor side rail rear section 42 are all retracted rearward with respect to the first side of the body 1. Moreover, the front sections of the two vehicle middle channel side beams and the front sections of the two vehicle floor longitudinal beams exceed the side edges of the body on the front floor assembly 6 and extend out towards the direction of the wheel base changing piece.
It will be appreciated that in the above case, when the front floor assembly is installed, the body 1 of the wheel base changing member can be overlapped on the front floor assembly 6 at the portions of the front sections of the two vehicle center tunnel side rails and the two vehicle floor side rail front sections beyond the side edges of the body on the front floor assembly 6, that is, beyond the side edges of the body on the front floor assembly 6, so as to give the wheel base changing member a supporting force directed vertically toward the vehicle interior. At this time, the body of the vehicle front floor assembly 6 overlaps the first side of the body 1, and the body of the vehicle front floor assembly 6 is located on the side close to the ground, and the two bodies are welded together.
As shown in fig. 2, in some embodiments of the present application, a third mounting hole 303 is provided at the second end of the first center tunnel side sill rear section 31, and a fourth mounting hole 304 is provided at the second end of the second center tunnel side sill rear section 32; the body 1 is provided with a fifth mounting hole and a sixth mounting hole.

The ninth mounting hole 403 and the eleventh mounting hole are connected together by a bolt; the tenth mounting hole 404 and the twelfth mounting hole are bolted together.
In some embodiments of the present application, a thirteenth mounting hole 201 and a fourteenth mounting hole 202 are provided on the rear section of the middle channel, and mounting holes are provided on the body 1 at positions corresponding to the thirteenth mounting hole 201 and the fourteenth mounting hole 202, respectively, and each pair of corresponding mounting holes are fixedly connected together by a bolt.
The mounting holes are arranged according to the requirement that the structures on the vehicle are matched with each other, and the mounting holes with different numbers and positions can be arranged according to the requirement.
As shown in fig. 2, in some embodiments of the present application, a plurality of reinforcing ribs are respectively provided on the rear center tunnel section 2 and the body 1, and each of the plurality of reinforcing ribs protrudes toward the ground.
It can be understood that the arrangement of the reinforcing ribs can not only enhance the strength and rigidity of the material, but also make the material not easy to deform under the condition of not increasing the thickness of the material.
It should be noted that the number and distribution of the reinforcing ribs can be set according to the requirements of the vehicle type. For example, as shown in fig. 1 and fig. 2, two parallel reinforcing ribs are respectively disposed on the body 1 along the width direction of the body 1 between the first center tunnel side sill rear section 31 and the first front floor side sill rear section 41, between the second center tunnel side sill rear section 32 and the second front floor side sill rear section 42, between the first rocker rear section 51 and the first front floor side sill rear section 41, and between the second rocker rear section 52 and the second front floor side sill rear section 42.
Meanwhile, two reinforcing ribs can be arranged on the middle channel rear section 2 along the length direction of the body 1.
It is to be understood that the length and width of the reinforcing rib are set as required, and are not limited herein. According to the drawing 2, the central axis of the body 1 is used as a symmetry axis, and a plurality of reinforcing ribs are symmetrically arranged, so that the stress of the wheel base changing piece is balanced, the whole structure is more stable, and the wheel base changing piece is not easy to deform.
In some embodiments of the present application, the sill rear section 5 includes a first sill rear section 51 and a second sill rear section 52.
The first end of the first sill rear section 51 and the first end of the second sill rear section 52 are respectively overlapped with a part of the sill front section and welded together, and two rows of welding spots are arranged on the overlapped parts.
In some embodiments of the application, the overlap is 50mm in the length direction of the rear threshold section 5.
As shown in fig. 3, it should be noted that the threshold front section includes a first threshold front section 8 and a second threshold front section 9. When the order of mounting the respective portions in the vehicle floor assembly is the first mounting order described above, that is, the order of mounting the middle floor assembly 7 first, then mounting the wheel base changing member, and finally mounting the front floor assembly 6, the first end of the first rocker rear section 51 and the first end of the second rocker rear section 52 overlap the surfaces in the width direction of the first rocker front section 8 and the second rocker front section 9, respectively, and the first rocker front section 8 and the second rocker front section 9 are located on the side close to the ground.
When the order of mounting the respective portions in the vehicle floor assembly is the second mounting order described above, that is, the front floor assembly 6 is mounted first, then the wheel base changing member is mounted, and finally the middle floor assembly 7 is mounted, the first end of the first rocker rear section 51 and the first end of the second rocker rear section 52 overlap with the width directions of the first rocker front section 8 and the second rocker front section 9, respectively, and the first end of the first rocker rear section 51 and the first end of the second rocker rear section 52 are located on the side close to the ground.
It can be understood that the two structures are connected more firmly by a fixing mode of overlapping a part of surfaces of the two structures and then welding the surfaces, and the two structures are not easy to break after being fixed.
In some embodiments of the present application, the second end of the first rocker rear section 51 and the second end of the second rocker rear section 52 are respectively overlapped with a portion of the body of the floor assembly 7 in the vehicle and welded together.
It should be noted that, regardless of whether the order of mounting the respective portions in the vehicle floor assembly is the first order of mounting or the second order of mounting, the second end of the first rocker rear section 51 and the second end of the second rocker rear section 52 are respectively overlapped with portions of the body of the floor assembly 7 in the vehicle that are close to the left and right door sides, and the second end of the first rocker rear section 51 and the second end of the second rocker rear section 52 are both located on the side close to the ground. Meanwhile, the second side of the body 1 is lapped with the body of the middle floor assembly 7, and the body 1 is positioned on one side close to the ground.
In some embodiments of the present application, a surface of the second end of the first rocker rear section 51 and a surface of the second end of the second rocker rear section 52 are both convex toward the ground, and the depth of the protrusion is the thickness of the floor body in the vehicle. The shape of the protrusion may be set according to the shape of the floor body in the vehicle.
It can be understood that, by the arrangement of the convex surfaces, when the second ends of the floor body and the first rocker rear section 51 and the second rocker rear section 52 in the vehicle are overlapped, the surface of the front rocker section close to the vehicle interior side and the surface of the rear rocker section close to the vehicle interior side are flush, so that the problems of tilting, easy deformation and the like caused by non-flush of the surface of the floor in the vehicle can be avoided.
It should be noted that, in the prior art, the center tunnel side sill, the front floor side sill and the side sill of the vehicle floor assembly are all a complete structure, but in the embodiment of the present application, it is equivalent to respectively cutting off the center tunnel, the center tunnel side sill, the front floor side sill and the side sill, so as to form a front part and a rear part.
In some embodiments of the present application, the length of the center tunnel rear section 2, the length of the center tunnel boundary beam rear section 3, and the length of the front floor stringer rear section 4 are respectively less than the length of the center tunnel front section, the length of the center tunnel boundary beam front section, and the length of the front floor stringer front section. The specific truncation position is determined according to the required variation of the vehicle type.
Meanwhile, the length of the rear threshold section 5 is smaller than that of the front threshold section, the cutoff position of the threshold is based on the material of the threshold, the material of the front threshold section is an ultrahigh-strength roll-pressing part, the material of the rear threshold section 5 is a cold-pressing part, and the strength of the ultrahigh-strength roll-pressing part is higher than that of the cold-pressing part, so that the length of the front threshold section is larger than that of the rear threshold section 5 in order to ensure the stability of the whole structure, and the specific length is determined according to requirements.
When the length of a vehicle model needs to be changed, the original axle distance changing piece can be disassembled and replaced by another axle distance changing piece with the whole length being lengthened or shortened, namely, each structure on the axle distance changing piece, namely, the axle distance changing piece with the length being respectively lengthened or shortened is formed by the body 1, the middle channel rear section 2, the middle channel side beam rear section 3 and the front floor longitudinal beam rear section 4, and the installation mode of the replaced axle distance changing piece is the same as that of the original axle distance changing piece.
When the rear threshold section 5 and the front threshold section are fastened together, the complete threshold is formed as shown in fig. 4a, the cross-section a-a of the threshold in fig. 4a being shown in fig. 4 b. In some embodiments of the present application, the width of the vehicle may be varied by varying the width of the sill section. The original doorsill can be replaced by the doorsill with the changed section width after being disassembled, and the replaced doorsill has the same assembly mode with the original doorsill.
By installing the axle distance changing piece between the front floor assembly 6 and the middle floor assembly 7 of the vehicle, when the axle distance of the vehicle needs to be changed, the axle distance of the vehicle can be changed only by replacing the original axle distance changing piece with an axle distance changing piece of another size after being detached and then installing the axle distance changing piece back to the original position. Because all parts on the vehicle floor structure do not need to be replaced, the development range is greatly reduced, the development period of the vehicle is shortened, and the cost is reduced. Simultaneously, thereby can satisfy the vehicle and to the demand of whole motorcycle type width through the width that changes the threshold cross-section, consequently its application scope is wider.
The embodiment of the application also provides a floor assembly which comprises a front floor assembly 6, a middle floor assembly 7 and any one of the wheel base changing pieces. Wherein the first side of the body 1 in the wheel base changing piece is fixed with the body of the front floor assembly 6, and the second side of the body 1 is fixed with the body of the middle floor assembly 7.
Specifically, the wheel base changing piece on the floor assembly comprises a body 1, a middle channel rear section 2, two middle channel side beam rear sections 3, two front floor longitudinal beam rear sections 4 and two threshold rear sections 5.
