Referring to fig. 1, in the present embodiment, a vehicle floor structure 100 includes a floor panel 110, a rear side frame 120, a front cross member 130, a rear cross member 140, and a battery mounting portion 150. The floor panel 110 is, for example, a plate structure provided at the bottom of a vehicle body (not shown) of the vehicle, the rear side frame 120 is, for example, a frame structure provided on the floor panel 110, the front cross member 130 and the rear cross member 140 are, for example, beam structures provided on the floor panel 110, and the battery mounting portion 150 is, for example, a portion on the floor panel 110 for mounting a battery (not shown) for supplying power to the vehicle. As such, the vehicle floor structure 100 is adapted to be mounted to the bottom of the vehicle body of the vehicle, and preferably disposed at the rear of the vehicle body, corresponding to vehicle parts such as a battery mounted at the rear of the vehicle body. However, the present invention is not limited to the use of the vehicle floor structure 100, and the installation position thereof on the vehicle may be adjusted as required.
Specifically, in the present embodiment, as shown in fig. 1, the rear side frames 120 are provided on the outer sides (e.g., in a left-right pair) of the floor panel 110 in the vehicle width direction (i.e., the vehicle left direction L and the vehicle right direction R), and extend in the vehicle front-rear direction (i.e., the vehicle front direction Fr and the vehicle rear direction Rr). As shown in fig. 1 and 2, the rear side frame 120 may be configured as a hollow frame body and has a top wall 122, an outer side wall 124 and an inner side wall 126, and fig. 1 and 2 show the vehicle floor structure 100 such that the top wall 122 of one side of the rear side frame 120 is removed to expose components (such as a first bulkhead 160, a trailing arm connecting part 170, a second bulkhead 180, etc., which will be described later) disposed inside the rear side frame 120, so as to describe the arrangement relationship of the components disposed inside the rear side frame 120. Preferably, the vehicle floor structure 100 is further provided with side sills 190. The side members 190 are provided on the outer sides of the rear side frames 120 in the vehicle width direction (e.g., as a pair of left and right sides), and extend in the vehicle front-rear direction. Among them, the outer side wall 124 of the rear side frame 120 in the vehicle width direction is formed by the side member 190, that is, the top wall 122 of the rear side frame 120 is connected to the side member 190 with the inner side wall of the side member 190 as the outer side wall 124. Further, the side sill 190 shown in fig. 1 and 2 may be a side sill inner panel, and further provided with a side sill outer panel and a sill reinforcement (not shown). However, the present invention does not limit the vehicle floor structure 100 to having a pair of rear side frames 120, the specific structure and interior components of the pair of rear side frames 120, and the relative positions of the rear side frames 120 and the side members 190 and the presence or absence of the side members 190. In embodiments where the side rail 190 is not provided, the rear side frame 120 may be additionally provided with an outer side wall 124 as an outer appearance surface of the rear side frame 120.
Further, in the present embodiment, the front cross member 130 and the rear cross member 140 are respectively provided on opposite sides of the rear side frame 120 in the vehicle front-rear direction (i.e., the vehicle front direction Fr and the vehicle rear direction Rr), and each extend in the vehicle width direction (i.e., the vehicle left direction L and the vehicle right direction R). Thus, the pair of rear side frames 120 extending in the vehicle front-rear direction and the front cross member 130 and the rear cross member 140 extending in the vehicle width direction intersect with each other to constitute a surrounding area. In addition, the battery mounting portion 150 is provided between the front cross member 130 and the rear cross member 140, and is preferably provided in a surrounding area constituted by the rear side frame 120, the front cross member 130, and the rear cross member 140. The battery mounting unit 150 may be, for example, an additional frame provided on the floor panel 110, or may be a part of the floor panel 110. However, the present invention is not limited to the specific structure of the front beam 130, the rear beam 140 and the battery mounting portion 150, and may be adjusted as needed.
Further, in the present embodiment, as shown in fig. 1 and 2, the outer side end 132 of the front cross member 130 in the vehicle width direction (i.e., the vehicle left direction L and the vehicle right direction R) forms the front end 128 of the rear side frame 120 in the vehicle front-rear direction (i.e., the vehicle front direction Fr and the vehicle rear direction Rr). That is, the outer side end 132 of the front cross member 130 in the vehicle width direction extends to the front of the rear side frame 120 in the vehicle front-rear direction, and the outer side end 132 of the front cross member 130 and the front end 128 of the rear side frame 120 correspond to each other. Preferably, the outer end 132 of the front cross member 130 in the vehicle width direction is connected to the side member 190 through the front end 128 of the rear side frame 120, whereby the outer end 132 of the front cross member 130 in the vehicle width direction forms the front end 128 of the rear side frame 120 in the vehicle front-rear direction. However, the present invention is not limited to the relative positions of the front cross member 130 and the rear side frame 120, and can be adjusted according to the requirement.
Accordingly, in the present embodiment, as shown in fig. 1 and 2, the outer side end 142 of the rear cross member 140 in the vehicle width direction (i.e., the vehicle left direction L and the vehicle right direction R) is connected to the inner side wall 126 of the rear side frame 120. Also, the interior of the rear side frame 120 (the exposed portion shown on one side thereof in fig. 1 and 2) is provided with a first bulkhead 160, the first bulkhead 160 partitions the interior of the rear side frame 120 in the vehicle front-rear direction (i.e., the vehicle front direction Fr and the vehicle rear direction Rr), and the first bulkhead 160 is aligned with the rear cross member 140 in the vehicle width direction (i.e., the vehicle left direction L and the vehicle right direction R). That is, the first bulkhead 160 provided inside the rear side frame 120 extends in the vehicle width direction to be connected to the inner side wall 126 of the rear side frame 120, and the first bulkhead 160 is aligned in the vehicle width direction with the rear cross member 140. Preferably, the first bulkhead 160 is connected to the front wall 144 of the rear cross member 140 in the vehicle front-rear direction via the inner side wall 126 of the rear side frame 120 (for example, the first bulkhead 160 and the front wall 144 of the rear cross member 140 are fixed to opposite side faces of the inner side wall 126 of the rear side frame 120 via welding), and the first bulkhead 160 has a rib 162 (shown in fig. 2) extending from the side sill 190 to the rear cross member 140 in the vehicle width direction. However, the present invention does not limit the relative position between the rear cross member 140 and the rear side frame 120, and can be adjusted according to the requirement.
As can be seen from this, in the present embodiment, through the above arrangement, when a side collision occurs in the vehicle (that is, an external force is applied to the side members such as the rear side frame 120 and the side member 190 from the outside of the vehicle), since the outer end 132 of the front cross member 130 in the vehicle width direction forms the front end 128 of the rear side frame 120 in the vehicle front-rear direction, the load applied from the side members such as the rear side frame 120 and the side member 190 can be transmitted to the front cross member 130, and since the first bulkhead 160 provided inside the rear side frame 120 and the rear cross member 140 are aligned in the vehicle width direction, the load applied from the side members such as the rear side frame 120 and the side member 190 can be transmitted to the rear cross member 140 through the first bulkhead 160. In this way, the load applied from the rear side frame 120 is dispersed to the front cross member 130 and the rear cross member 140, and thereby deformation of the battery mounting portion 150 provided inside the rear side frame 120 and between the front cross member 130 and the rear cross member 140 is suppressed. Accordingly, the vehicle floor structure 100 can secure structural rigidity with a simple structure, and suppress deformation of the battery mounting portion 150 at the time of a side collision of the vehicle.
In the present embodiment, as shown in fig. 1 and 2, a trailing arm connecting member 170 is provided inside the rear side frame 120 (an exposed portion shown on one side of fig. 1 and 2). The trailing arm connecting member 170 refers to a connecting member for connecting to a trailing arm (not shown) provided on a vehicle body. Preferably, the first bulkhead 160 connects the front ends of the trailing arm connecting members 170 in the vehicle front-rear direction. In this way, during a side collision of the vehicle, not only can the load applied from the rear side frame 120 be transmitted to the rear cross member 140 via the first bulkheads 160, thereby suppressing deformation of the battery mounting portion 150, but also the load applied from the trailing arm and the trailing arm connection member 170 can be transmitted to the rear cross member 140 via the first bulkheads 160, thereby increasing the rigidity of the trailing arm connection member 170, and suppressing deformation of the trailing arm connection member 170 during the side collision of the vehicle.
In the present embodiment, as shown in fig. 1 and 2, the trailing arm connecting member 170 has a convex portion 172 that protrudes upward (i.e., in the vehicle upward direction U shown in fig. 2), a second bulkhead 180 is provided inside the rear side frame 120 (at an exposed portion shown on one side of fig. 1 and 2), the second bulkhead 180 is disposed above the convex portion 172, and the second bulkhead 180 is disposed between the rear cross member 140 and the wheel house portion 102 located rearward of the rear cross member 140 in the vehicle longitudinal direction. That is, the second bulkhead 180 is located more rearward (i.e., on the side corresponding to the vehicle rear direction Rr) than the first bulkhead 160 that is aligned in the vehicle width direction on the rear cross member 140. As described above, at the time of a side collision of the vehicle, not only the load applied from the rear side frame 120 can be transmitted to the rear cross member 140 via the second bulkhead 180, thereby suppressing deformation of the battery mounting portion 150, but also the load applied from the wheel house 102, the trailing arm, and the trailing arm connecting member 170 can be transmitted to the rear cross member 140 via the second bulkhead 180, thereby increasing the rigidity of the wheel house 102 and the trailing arm connecting member 170, and thereby suppressing deformation of the wheel house 102 and the trailing arm connecting member 170 at the time of a side collision of the vehicle. However, the present invention is not limited to the installation position and installation of the second frame spacer 180, and it can be adjusted according to the requirement.
To sum up, the utility model discloses an among the vehicle floor structure, front beam and rear frame set up respectively in the relative both sides of rear frame in the vehicle fore-and-aft direction, and the outside end of front beam forms the front end of rear frame, and the inside of rear frame is equipped with first bulkhead to first bulkhead and rear frame are side by side in vehicle width direction. In this way, when a side collision occurs in the vehicle, the load applied from the rear side frame can be transmitted to the front cross member and transmitted to the rear cross member via the first bulkhead, thereby suppressing deformation of the battery mounting portion provided between the front cross member and the rear cross member. Preferably, the rear side frame is provided inside with a second bulkhead disposed between the rear cross member and the wheel house portion in the vehicle front-rear direction, so that the load transmitted from the rear cross member and the wheel house portion can be transmitted to the rear cross member via the second bulkhead, thereby suppressing deformation of the battery mounting portion. Accordingly, the vehicle floor structure of the present invention can ensure structural rigidity with a simple structure, thereby suppressing deformation of the battery mounting portion when a side collision occurs in the vehicle.
