Description

Technical Field

[0001] This utility model relates to the technical field of front floor structure of a vehicle body, and particularly to a front floor structure of a vehicle body. Background Technology

[0002] To enhance the rigidity of existing vehicle floor structures, reinforcing ribs are typically stamped onto the surface of the vehicle floor structure. For example, Chinese utility model patent CN204587042U discloses a vehicle floor structure and mentions that by using a combination of concave ribs and long ribs on the vehicle floor body, the rigidity of the vehicle floor body can be effectively improved while reducing vibration.

[0003] However, the aforementioned patent directly stamps a large number of reinforcing ribs onto the vehicle floor structure, which leads to high processing difficulty. Furthermore, when stamping a large number of reinforcing ribs, cracks and wrinkles may easily occur in the vehicle floor structure, affecting the finished product qualification rate.

[0024] A front floor structure for a vehicle body, such as Figures 1-5 As shown, it includes a central channel section 2, two side wings 1 extending to both sides of the central channel section 2, a first lateral reinforcing component 3 and a second lateral reinforcing component 4 provided on each of the two side wings 1, and a central channel reinforcing plate 5 provided on the central channel section 2.

[0025] The central channel section 2 and the two side wing sections 1 are integrally stamped and formed. The first transverse reinforcing component 3 and the second transverse reinforcing component 4 are welded to the side wing sections 1. The central channel reinforcing plate 5 is fixedly connected to the central channel section 2 by multiple bolts. The second transverse reinforcing component 4 is located on the front side of the side wing section 1, and the first transverse reinforcing component 3 is located in the middle of the side wing section 1.

[0026] like Figure 2 As shown, the first lateral reinforcing component 3 includes a first reinforcing member 31 and a first adapter 32. The first reinforcing member 31 is disposed on the side wing portion 1, and the first adapter 32 is fixedly connected to the first reinforcing member 31, as shown. Figures 3-4 As shown, one end of the first adapter 32 is attached to the outer wall of the central channel reinforcing plate 5;

[0027] Specifically, such as Figure 4 and Figure 5 As shown, the first reinforcing member 31 includes a first arched portion 311, and a first fitting portion 312 extending to the front and rear sides and the left side of the first arched portion 311. The first fitting portion 312 is fitted to and welded to the side wing portion 1. A plurality of first protrusions 313 are formed on the front and rear sides of the first fitting portion 312. By providing a plurality of first protrusions 313, the rigidity of the first reinforcing member 31 can be strengthened. The number of first protrusions 313 can be set according to the actual situation and is not limited here. The first protrusions 313 extend from the outside of the first fitting portion 312 to the first arched portion 311. The first arched portion 311, the first fitting portion 312 and the first protrusions 313 are integrally stamped and formed.

[0028] The first adapter 32 includes a second arched portion 321, a second fitting portion 322 formed on the front and rear sides of the second arched portion 321, and a first raised portion 323 extending upward to the right side of the second arched portion 321. The second fitting portion 322 fits and is welded to the side wing portion 1. The inner top wall of the second arched portion 321 fits and is fixedly connected to the right side of the first arched portion 311 by bolts. The first raised portion 323 fits and abuts against the outer wall of the central channel reinforcing plate 5, and can compress and fix the central channel reinforcing plate 5. Thus, the first transverse reinforcing component 3 is composed of the first reinforcing member 31 and the first adapter 32. Both components are manufactured separately, which reduces the manufacturing difficulty. Moreover, the first transverse reinforcing component 3 can effectively strengthen the transverse rigidity of the middle part of the front floor structure of the vehicle body. The first adapter 32 is also integrally stamped.

[0029] like Figure 2 As shown, the second lateral reinforcing component 4 includes a connector 41 disposed on the side wing portion 1, a second adapter 43 disposed at the junction of the side wing portion 1 and the central channel portion 2, and a second reinforcing member 42 disposed between the second adapter 43 and the connector 41, as shown. Figures 3-4 As shown, a portion of the second adapter 43 is inserted between the inner wall of the central channel reinforcing plate 5 and the outer wall of the central channel section 2;

[0030] Specifically, such as Figure 4 and Figure 5As shown, the connector 41 includes a third arched portion 411, a third fitting portion 412 extending to the front and rear sides of the third arched portion 411, and a flat portion 413 extending to the right side of the third arched portion 411. The flat portion 413 fits against the upper left surface of the fourth arched portion 424, and the third arched portion 411 is fixedly connected to the fourth arched portion 424 by bolts. The third fitting portion 412 is welded to the side wing portion 1. The connector 41 is integrally stamped. The second reinforcing member 42 includes a fourth arched portion 424, a fourth fitting portion 421 extending to the front and rear sides of the fourth arched portion 424, the fourth fitting portion 421 being welded to the side wing portion 1, and a plurality of second protrusions 422 formed on the fourth fitting portion 421. The second protrusions 422 are used to strengthen the rigidity of the second reinforcing member 42. The fourth arched portion 411... The upper surface of 24 has two flat, straight grooves 423. The rigidity of the second reinforcing member 42 is further enhanced by setting the grooves 423. The second reinforcing member 42 is integrally stamped. The second adapter 43 includes a fifth arched part 431, a mating surface 432 formed on the left side of the fifth arched part 431, and a second raised part 433 extending to the front, back and right side of the fifth arched part 431. The front and back sides of the second raised part 433 are welded to the connection between the side wing part 1 and the central channel part 2. The mating surface 432 is mated to the right side of the upper surface of the fourth arched part 424. The fifth arched part 431 and the right side of the fourth arched part 424 are fixedly connected by bolts. The end of the second raised part 433 is located between the outer wall of the central channel part 2 and the inner wall of the central channel reinforcing plate 5. The second adapter 43 is integrally stamped.

[0031] The shape of the central channel reinforcing plate 5 is adapted to the central channel section 2, and it is fixedly connected to the central channel section 2 by multiple bolts. The central channel section 2 is integrally stamped.

[0032] In summary, the central channel reinforcement plate 5 can enhance the rigidity of the central channel section 2. The first transverse reinforcement component 3 is used to enhance the transverse rigidity of the middle part of the front floor structure, and the second transverse reinforcement component 4 is used to enhance the transverse rigidity of the front side of the front floor structure. Furthermore, the first protruding part 323 in the first transverse reinforcement component 3 abuts against the middle of the outer wall of the central channel reinforcement plate 5, further fixing the central channel reinforcement plate 5 to the central channel section 2 and improving rigidity. The second protruding part 433 is inserted between the inner wall of the central channel reinforcement plate 5 and the outer wall of the central channel section 2, thereby enhancing rigidity. The second raised portion 433 can be further fixed by the central channel reinforcement plate 5 and the central channel portion 2, and the two sides of the second reinforcement member 42 can be fixedly connected by the second adapter 43 and the connector 41, so that the second reinforcement member 42 can be firmly fixed to the front floor structure, thereby strengthening the rigidity of the front floor structure. In addition, since the components in the first transverse reinforcement assembly 3 and the second transverse reinforcement assembly 4 and the central channel reinforcement plate 5 are all made separately, the front floor structure can be processed more easily, reducing the processing difficulty and making the entire front floor structure easier to manufacture.
