Moreover, the described specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0042] Please refer to Figures 1-4 The embodiment of the present application provides a rear floor assembly, the rear floor assembly is used for constituting a vehicle body of a vehicle, and the rear floor assembly comprises a rear floor 100, a rear wall 200, a front cross beam 300 and a structure reinforcing piece 400.

[0043] The rear floor 100 has a receiving portion 110 for receiving a spare tire. The rear floor 100 includes a front section panel 130 and a rear section panel, which are connected in sequence along the length direction of the vehicle body, and the receiving portion 110 is a recessed portion of the rear section panel.

[0044] The rear wall 200 is arranged at the rear end of the receiving portion 110 and is connected with the receiving portion 110. The rear wall 200 is arranged at the rear end of the rear floor 100, is arranged substantially vertically and extends along the width direction of the vehicle, and serves as a bottom baffle of the trunk of the vehicle and can jointly define a spare tire pool with the receiving portion 110 to place the spare tire.

[0045] The front cross beam 300 is located at the front end of the receiving portion 110, i.e., the end away from the rear wall 200, and is specifically located at the position where the front section panel 130 and the rear section panel are connected. The front cross beam 300 is supported on the outer wall of the receiving portion 110, so that the receiving portion 110 can transmit force to the front cross beam 300. The front cross beam 300 is connected with other structural members of the vehicle body, so that the force can be transmitted to other structural members of the vehicle body.

[0046] The structural reinforcement 400 is connected to the receiving portion 110 and is used to support the spare tire. The projection of the front end of the structural reinforcement 400 on the horizontal plane partially overlaps the projection of the front cross beam 300 on the horizontal plane.

[0047] It can be understood that the structural reinforcement 400 arranged in the receiving portion 110 can jointly support the spare tire with the receiving portion 110, improve the support stiffness of the spare tire, and effectively suppress the vibration of the receiving portion 110 caused by the vibration of the spare tire. Moreover, since the projection of the front end of the structural reinforcement 400 on the horizontal plane partially overlaps the projection of the front cross beam 300 on the horizontal plane, the structural reinforcement 400 can transmit the force to the front cross beam 300, which further reduces the vibration and noise of the receiving portion 110 caused by the vibration of the spare tire.

[0048] The connection mode of the rear wall 200 and the receiving portion 110 is not limited, and in some embodiments, the side of the receiving portion 110 facing the rear wall 200 is open. The side of the receiving portion 110 facing the rear wall 200 has a folded edge that can be attached to the rear wall 200 and welded.

[0049] In some embodiments, the rear end of the structural reinforcement 400 is connected to the rear wall 200 to transmit force to the rear wall 200. Thus, the structural reinforcement 400 can transmit the force to the rear wall 200, and the rear wall 200 and the structural reinforcement 400 jointly support the spare tire, which further suppresses the vibration and noise of the receiving portion 110 caused by the vibration of the spare tire.

[0050] It can be understood that when the projection of the front end of the structural reinforcement 400 on the horizontal plane partially overlaps the projection of the front cross beam 300 on the horizontal plane, the rear end of the structural reinforcement 400 is connected to the rear wall 200 to transmit force to the rear wall 200. Then both the front and rear ends of the structural reinforcement 400 can transmit force, thereby further reducing the stress on the storage part 110, thereby reducing the vibration and noise of the storage part 110 caused by the spare tire.

[0051] It can be understood that the structural reinforcement 400 can be integrally formed on the rear floor 100. For example, it can be a protruding rib structure integrally formed with the rear floor 100, at which time the structural reinforcement 400 can directly extend to the front cross beam 300. The structural reinforcement 400 can also be separately formed from the rear floor 100 and then fixedly connected to the storage part 110.

[0052] The following will be described taking the structural reinforcement 400 and the rear floor 100 as an example:

[0053] Please refer to Figure 4 In some embodiments, the structural reinforcement 400 includes a first rib 410 and a second rib 420, both of which are fixedly connected to the inner wall of the storage part 110. The first rib 410 and the second rib 420 can be spaced apart and arranged in parallel, and both the first rib 410 and the second rib 420 extend substantially in the front-rear direction of the vehicle.

[0054] In other embodiments, the first rib 410 and the second rib 420 are spaced apart at one end toward the rear wall 200, and the other end of the first rib 410 away from the rear wall 200 and the other end of the second rib 420 away from the rear wall 200 are connected to each other to form a common end. The projection of the common end on the horizontal plane partially overlaps the projection of the front cross beam 300 on the horizontal plane, thereby being able to support on the front cross beam 300.

[0055] It can be understood that the other end of the first rib 410 away from the rear wall 200 and the other end of the second rib 420 away from the rear wall 200 are connected to each other to form a common end, and the force applied to a certain part can be more evenly distributed on multiple ribs rather than concentrated in a single area. This helps to reduce local stress concentration, thereby reducing the risk of material fatigue or rupture. In addition, the combined first rib and second rib can help reduce the resonance effect.

[0056] In some specific embodiments, the first rib 410 and the second rib 420 can be two ribs intersecting at an acute angle, and the first rib 410 and the second rib 420 can be integrally formed to improve the connection strength and reduce the assembly process.

[0057] In some embodiments, the structural reinforcement 400 includes a third rib 430, the two ends of the third rib 430 are connected to the first rib 410 and the second rib 420 respectively. The third rib 430 can be integrally formed with the first rib 410 and the second rib 420. The first rib 410, the second rib 420 and the third rib 430 form a triangular structure. In this way, the first rib 410, the second rib 420 and the third rib 430 can form a more integral structure, making it more difficult to bend or twist, thereby improving the resistance to impact load.

[0058] The third rib 430 extends to the middle of the first rib 410 and the second rib 420 in the length direction, and the width of the joint of the first rib 410, the second rib 420 and the third rib 430 is widened, thereby improving the strength of the joint. The middle of the first rib 410, the second rib 420 and the third rib 430 can form a hollow hole to save materials.

[0059] In some embodiments, the first rib 410 and the second rib 420 each include a rib body 421 protruding from the opposite connecting edge 422, and the connecting edge 422 includes a plurality of welding portions distributed along the length direction of the rib body 421, and the first rib 410 and the second rib 420 are connected to the receiving portion 110 by the welding portions. The connecting edge 422 is arranged against the receiving portion 110, so as to facilitate welding connection.

[0060] In order to save materials, the connecting edge 422 includes a plurality of tabs protruding in the width direction of the rib body 421, and each welding portion is formed in the middle of the tab.

[0061] In some embodiments, the height of at least part of the first rib 410 gradually changes along the length direction of the first rib 410, and the height of at least part of the second rib 420 gradually changes along the length direction of the second rib 420, so that the vibration frequency of at least part of the first rib 410 and the second rib 420 in the length direction is different, further avoiding resonance.

[0062] Please refer to Figure 3 In order to improve the stiffness of the receiving portion 110, in some embodiments, part of the receiving portion 110 protrudes to form a reinforcing rib 120, and the reinforcing rib 120 is a protruding rib structure formed by stamping. The receiving portion 110 and the reinforcing rib 120 can be simultaneously formed by stamping the rear floor 100 to improve the production efficiency. The structural reinforcement 400 is supported on the reinforcing rib 120, and the reinforcing rib 120 has a welding position corresponding to the welding portion.

[0063] It can be understood that the reinforcing rib 120 can improve the rigidity and deformation resistance of the local area. By arranging the welding position on the reinforcing rib 120, and welding the welding part of the structure reinforcing part 400 with the welding position, the carrying capacity and the deformation resistance of the structure reinforcing part 400 can be further improved.

[0064] In some embodiments, the number of reinforcing ribs 120 is multiple, which are distributed on the side wall and the bottom wall of the accommodating part 110. Each reinforcing rib 120 is relatively dispersed on the side wall and the bottom wall of the accommodating part 110, and there is a gap between adjacent reinforcing ribs 120. Among them, part of the reinforcing ribs 120 are distributed on the side wall of the accommodating part 110 and the bottom wall of the accommodating part 110 at the same time. In this way, the rigidity of the side wall and the bottom wall of the accommodating part 110 as a whole can be improved, and the force applied to the bottom wall can also be dispersed, so that the force is more evenly distributed on a larger area, thereby avoiding stress concentration and reducing the risk of local overload.

[0065] Among them, a plurality of reinforcing ribs 120 are also punched on the front panel 130, and the plurality of reinforcing ribs 120 of the front panel 130 can extend to the accommodating part 110, thereby improving the rigidity of the whole and being capable of transmitting part of the force to the front panel 130.

[0066] Please refer to Figure 4 In order to facilitate the preparation of the structure reinforcing part 400, in some embodiments, the structure reinforcing part 400 comprises a support part 401 and a connecting part 402. The support part 401 is connected with the accommodating part 110, and the connecting part 402 is connected with the rear wall 200. Among them, the support part 401 and the connecting part 402 are formed separately. Among them, the support part 401 comprises the first rib 410, the second rib 420 and the third rib 430 which connect the accommodating part 110. The connecting part 402 is partially overlapped on the support part 401 and is welded and fixed.

[0067] It can be understood that by forming the support part 401 and the connecting part 402 separately, the difficulty of forming the structure reinforcing part 400 is reduced, and the difficulty and cost of mold development are reduced.

[0068] In some embodiments, the support part 401 comprises the first rib 410 and the second rib 420, and the number of the connecting part 402 is two, which are respectively connected with the first rib 410 and the second rib 420. Specifically, one end of the first rib 410 and the second rib 420 is combined, and the other end is respectively connected with one connecting part 402.

[0069] The connecting portion 402 comprises a first connecting segment 4021 and a second connecting segment 4022 connected with each other, and the first connecting segment 4021 and the second connecting segment 4022 have an included angle therebetween. The first connecting segment 4021 is fixedly connected with the supporting portion 401, and the second connecting segment 4022 is fixedly connected with the rear wall 200. Specifically, the first connecting segment 4021 and the second connecting segment 4022 are stamped and formed, and the first connecting segment 4021 can be fixedly connected with the supporting portion 401 by welding. The second connecting segment 4022 can also be fixedly connected with the rear wall 200 by welding.

[0070] The connecting portion 402 can be formed with a hollow hole in the middle to save materials.
