However, the directions in the specification and the drawings are not intended to limit the configuration of the present invention, and may be adjusted according to actual needs.

Referring to fig. 1 and fig. 2, in the present embodiment, a vehicle floor structure 100 includes a floor panel 110, a floor cross member 120, and a first channel reinforcing member 130 (see fig. 2). The floor panel 110 is disposed at the bottom of the vehicle and has a floor tunnel 112. The floor tunnel 112 extends in the vehicle front-rear direction X at a central position of the floor panel 110 in the vehicle width direction Y, and projects upward. The floor tunnel 112 includes a pair of side walls 112a and a ceiling wall 112b, the pair of side walls 112a being disposed on opposite sides in the vehicle width direction Y and facing each other, and the ceiling wall 112b being disposed above the height direction Z so as to connect the side walls 112a located on opposite sides in the vehicle width direction Y. In other words, the floor tunnel 112 may be regarded as a cover-like structure in which the central position of the floor panel 110 is recessed from below to above and the opening is directed downward, when viewed from the front to the rear in the vehicle front-rear direction X (as viewed in fig. 2), but the present invention is not limited thereto.

In the present embodiment, the floor cross member 120 is provided on the floor panel 110 so as to extend in the vehicle width direction Y, and connects the side walls 112a of the floor tunnel 112 on the opposite sides in the vehicle width direction Y. Further, the pair of floor cross members 120 correspondingly connect the pair of side walls 112a on the opposite sides of the floor tunnel 112 in the vehicle width direction Y, but the present invention is not limited thereto. As shown in fig. 2, the first tunnel reinforcing member 130 is provided below the floor tunnel 112 so as to extend in the vehicle width direction Y, and the first tunnel reinforcing member 130 and the floor cross member 120 are arranged in the vehicle width direction Y. Further, the first channel reinforcing member 130 is located between the pair of floor beams 120, so that the floor beams 120 are connected to the outer side surface of the side wall 112a and the first channel reinforcing member 130 is connected to the inner side surface of the side wall 112a in parallel, but the present invention is not limited thereto.

Further, in the present embodiment, as shown in fig. 2, the first passage reinforcing member 130 includes an upper member 132 and a lower member 134. The upper member 132 is provided above the center of the floor tunnel 112 in the height direction Z, and the upper member 132 and the floor tunnel 112 form a continuous cross section therebetween. The lower member 134 is provided below the upper member 132, and extends obliquely upward from the side wall 112a of the floor tunnel 112 toward the center in the vehicle width direction Y. The upper member 132 is, for example, a cover with an upward opening, and covers the top wall 112b of the bottom plate passage 112 to form a hollow trapezoidal cross section with the top wall 112b, but the present invention is not limited thereto.

As described above, in the vehicle floor structure 100 of the present invention, the floor tunnel 112 is reinforced in rigidity by the first tunnel reinforcement member 130 provided below the floor tunnel. The first tunnel reinforcing member 130 includes an upper member 132 and a lower member 134, and when the vehicle is impacted, the upper member 132 transmits an external force from one side of the vehicle width direction Y to the floor cross member 120 located on the opposite side, and the lower member 134 transmits an external force from a lower side of the one side of the vehicle width direction Y to the upper member 132 and the floor cross member 120 located on the opposite side. In this way, the rigidity of the floor tunnel 112 can be improved, and the floor tunnel 112 can be effectively inhibited from deforming when subjected to a force. Accordingly, the vehicle floor structure 100 of the present invention can maintain high rigidity without increasing the number of sheets.

Referring to fig. 2 and 3, in detail, in the embodiment, the lower member 134 includes a truss portion 134a and a connecting portion 134 b. The truss portion 134a is formed in a truss shape in the vehicle width direction Y to connect the upper member 132, and the truss portion 134a includes a first joint portion FM and a second joint portion SM (shown in fig. 3). The first engaging portion FM is engaged with the lower surface of the backplane board 110. The second engaging portion SM engages with the side wall 112a of the floor tunnel 112. In this way, the truss portion 134a extends obliquely upward from the side wall 112a toward the center in the vehicle width direction Y to connect the upper member 132. Accordingly, the connection portion 134b connects the truss portions 134a at the opposite sides, and the connection portion 134b extends along the lower surface of the upper member 132, but the present invention is not limited thereto. Accordingly, when the vehicle is impacted, the truss portion 134a can transmit the external force from the lower portion of one side in the vehicle width direction Y to the truss portion 134a located on the opposite side through the connecting portion 134b, that is, to the floor cross member 120 located on the opposite side, thereby increasing the rigidity of the floor tunnel 112 to suppress deformation and vibration.

Referring to fig. 4, in the present embodiment, seat brackets 140 are respectively disposed at the front and rear of the floor cross member 120 in the vehicle front-rear direction X. The seat bracket 140 is connected to the side wall 112a of the floor tunnel 112. A connection bracket 150 connected to an exhaust pipe (not shown) is provided below the floor tunnel 112, and the seat bracket 140 is connected to the connection bracket 150 through the floor tunnel 112. In addition, the vehicle floor structure 100 further includes a second tunnel reinforcement member 160. The second channel reinforcing member 160 is provided at the corner C of the floor tunnel 112, and extends in the longitudinal direction of the floor tunnel 112 (i.e., in the vehicle front-rear direction X). The connection bracket 150 is connected to the second channel reinforcing member 160 through the floor channel 112. It is understood that the external force transmitted from below or from the exhaust pipe to the floor tunnel 112 through the connecting bracket 150 can be shared by the seat bracket 140 and the second tunnel reinforcing member 160 having high rigidity, thereby suppressing the vibration of the exhaust pipe and the noise generated by the vibration. However, the present invention is not limited to the seat frame 140, the connecting frame 150, and the second channel reinforcing member 160, and may be adjusted as needed.

In the present embodiment, as shown in fig. 5, the connecting bracket 150 connects the side wall 112a and the top wall 112b of the floor tunnel 112, and extends toward the side wall 112a and the top wall 112b in the vehicle width direction Y and the height direction Z to form a frame structure, for example, but the present invention is not limited thereto. Also, the connecting bracket 150 includes a partition portion 152 to partition the lower side of the floor tunnel 112 in the vehicle front-rear direction X. As such, the partition portion 152 may serve as a support of the floor tunnel 112 to share an external force directly transmitted into the floor tunnel 112, and further enhance the rigidity of the floor tunnel 112 to suppress deformation and vibration.

Referring to fig. 6, in the present embodiment, the vehicle floor structure 100 further includes a floor cross member reinforcing member 170. The floor cross member 170 is disposed in the space S formed between the floor cross member 120 and the floor panel 110, and the floor cross member 170 is disposed at a position above the space S. Specifically, the floor cross member 170 is provided along the upper edge of the inner side wall of the floor cross member 120. The floor cross member reinforcing member 170 is formed in a lid-like structure with its opening facing downward when viewed from the outside to the inside in the vehicle width direction Y (see fig. 6), but the present invention is not limited thereto. Such an arrangement can further enhance the rigidity of the floor cross member 120, and suppress deformation and vibration.

In summary, in the vehicle floor structure of the present invention, the floor tunnel is reinforced in rigidity by the first tunnel reinforcing member disposed below the floor tunnel. The first tunnel reinforcing member includes an upper member for transmitting an external force from one side of the vehicle width direction to the floor cross member located on the opposite side when the vehicle is impacted, and a lower member for transmitting an external force from the lower side of the one side of the vehicle width direction to the upper member and the floor cross member located on the opposite side. Therefore, the rigidity of the bottom plate channel can be improved, and the deformation of the bottom plate channel when the bottom plate channel is stressed can be effectively inhibited. Further, the external force transmitted from below or from the exhaust pipe to the floor tunnel via the connecting bracket can be shared by the seat bracket and the second tunnel reinforcing member having high rigidity, thereby suppressing vibration of the exhaust pipe and noise generated by the vibration. Accordingly, the utility model discloses a vehicle floor structure can maintain higher rigidity under the condition that does not increase panel.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the scope of the embodiments of the present invention.
