According to the utility model discloses hasp reinforcing plate 100 of first aspect embodiment is applied to the body structure and is used for installing hasp nut box 500, and the body structure includes C post reinforcing plate 200 and wheel casing 300. Referring to fig. 1 to 2, the latch reinforcement plate 100 has a first connection portion fixedly connected to the C-pillar reinforcement plate 200, a second connection portion fixedly connected to the wheel cover 300, and a mounting portion for mounting the latch nut box 500.
By fixedly connecting the striker reinforcement plate 100 between the C-pillar reinforcement plate 200 and the wheel house 300, both side portions of the striker reinforcement plate 100 are fixed, and thus the striker reinforcement plate 100 has a large dynamic stiffness. When the automobile runs, the dynamic stiffness of the latch reinforcing plate 100 is high enough, so that the latch reinforcing plate 100 is prevented from generating vibration due to insufficient dynamic stiffness, and then abnormal sound is generated. In addition, in the process of closing the door, the acting force of the door on the latch structure is absorbed by the latch reinforcing plate 100, and the latch reinforcing plate 100 transmits the absorbed force to the C-pillar reinforcing plate 200 and the wheel cover 300, so that the dynamic stiffness of the latch reinforcing plate 100 is high, and the sound quality of the closed door of the automobile is ensured.
It can be understood that part of the stress of the striker reinforcement plate 100 is absorbed by the wheel cover 300, and the wheel cover 300 has sufficient strength to ensure that the stress of the striker reinforcement plate 100 is stably absorbed.
Moreover, the dynamic stiffness of the latch reinforcement plate 100 is sufficiently large, and the safety of torsion, bending stiffness and the like of the local vehicle body position of the rear door latch is improved.
It should be noted that the first connecting portion is a corresponding area on one side of the latch reinforcement plate 100, and the area is connected to the C-pillar reinforcement plate 200 by welding, which will be described in detail later. The second connecting portion is a corresponding region on the other side of the striker reinforcement plate 100, which is welded to the wheel cover 300, as will be described in detail later.
In some embodiments, referring to fig. 1 to 5, the latch reinforcement plate 100 includes a first connection section 110, a second connection section 120, and a first bending portion 130 integrally connected between the first connection section 110 and the second connection section 120 along a length direction thereof. The end of the first connecting section 110 away from the first bent portion 130 extends obliquely downward to the seam allowance region 310 of the wheel cover 300 to be able to connect with the seam allowance region 310. The first connecting section 110 and the wheel opening area 320 of the wheel cover 300 are arranged at intervals, the first connecting section 110 and the wheel opening area 320 of the wheel cover 300 form an accommodating cavity, the side surface of the first connecting section 110 close to the wheel opening area 320 is an installation part, and the locking nut box 500 is fixedly installed on the side surface of the first connecting section 110 close to the wheel opening area 320 and is located in the accommodating cavity. The end of the second connecting segment 120 away from the first bent portion 130 extends obliquely upward to the wheel opening area 320 of the wheel cover 300 so as to be able to connect with the wheel opening area 320.
By adopting the above scheme, firstly, the lock catch reinforcing plate 100 is connected to the spigot area 310 of the wheel cover 300 and the wheel opening area 320 of the wheel cover 300, so that the two areas of the wheel cover 300 can absorb the stress of the lock catch reinforcing plate 100, and the dynamic stiffness of the lock catch reinforcing plate 100 can be better ensured; secondly, the lock catch reinforcing plate 100 is just hidden in the bending region of the wheel cover 300, i.e. the bending region of the seam allowance region 310 and the wheel opening region 320, and the locking nut box 500 is hidden in the area where the seam allowance area 310 and the wheel opening area 320 are bent, the structure saves the space of the vehicle body structure, ensures that all the accessories of the vehicle body structure can be tightly installed, thereby ensuring the strength of the vehicle body structure and thus having a better improvement in the dynamic stiffness of the striker reinforcement plate 100, for example, because the buckle reinforcing plate 100 is hidden in the bending area of the wheel cover 300, the C-pillar reinforcing plate 200 can be better tightly connected with the wheel cover 300, the side-wall outer plate 400 outside the C-pillar reinforcing plate 200 can be tightly connected with the C-pillar reinforcing plate 200 and the wheel cover 300, thereby improving the tightness of the vehicle body structure, improving the strength of the vehicle body structure and further ensuring the dynamic rigidity of the lock catch reinforcing plate 100; thirdly, through the arrangement of the first bending part 130, the first connecting section 110 and the second connecting section 120 are close to each other, and the latch reinforcing plate 100 is better accommodated between the seam allowance area 310 and the wheel opening area 320; moreover, the first bending portion 130 enables the outer surfaces of the first connecting section 110 and the second connecting section 120 to be just adapted to the inner surface of the C-pillar reinforcement plate 200, so that the outer surfaces of the first connecting section 110 and the second connecting section 120 can be welded to the inner surface of the C-pillar reinforcement plate 200, thereby ensuring the connection strength between the latch reinforcement plate 100 and the C-pillar reinforcement plate 200 and further improving the dynamic stiffness of the latch reinforcement plate 100.
