[0022] See also Figure 1-2The utility model provides a technical solution: a locking mounting point reinforcement plate structure, including a reinforcement plate body 1, the reinforcement plate body 1 is an integrated structure composed of a connecting portion 2, an inner reinforcing rib portion 3 and an outer reinforcing rib portion 4, and the connecting portion 2, the inner reinforcing rib portion 3 and the outer reinforcing rib portion 4 are special-shaped parts made of steel plates through a stamping process, the inner reinforcing rib portion 3 and the outer reinforcing rib portion 4 are staggered on both sides of the connecting portion 2, and a locking mounting point 9 is provided at the lower end of the connecting portion 2, and the reinforcement plate body 1 is welded and fixed to a corresponding position on the vehicle body through one side of the inner side of the connecting portion 2, the inner reinforcing rib portion 3 and the outer reinforcing rib portion 4. The reinforcement plate body 1 of this structure is connected to the vehicle body through a bracket structure composed of the connecting portion 2, the inner reinforcing rib portion 3 and the outer reinforcing rib portion 4. The installation position is multi-point welded, and the lock buckle installation point 9 is used to fix the lock buckle. In this way, the reinforcement plate body 1 increases the number of welding points with the vehicle body by optimizing the structure to improve the rigidity of the door lock buckle installation point, solves the problem of local structural deformation caused by insufficient rigidity of the vehicle door lock buckle installation point, improves the user experience of the driver and passengers, and can also improve the door closing sound quality, and can adapt to the long-term use of the vehicle under harsh working conditions. The lock buckle installation point 9 is a round hole structure, and the lock buckle installation point 9 is provided with two at the lower end of the connecting part 2. The lock buckle installation point 9 of this structure can cooperate to install the lock buckle firmly, and the lower end of the inner reinforcing rib part 3 is provided with a recessed reinforcing rib 6 at the position corresponding to the lock buckle installation point 9, and the gap between the recessed reinforcing ribs 6 is A bolt hole 8 is provided. The recessed reinforcing rib 6 of this structure can reinforce the position where the reinforcing plate body 1 contacts the lock buckle, ensuring the strength of the reinforcing plate body 1 at the installation position of the lock buckle, and is not prone to deformation. The bolt hole 8 can also cooperate with the installation of the lock buckle to further ensure the stability of the lock buckle after installation. A through hole 5 is provided in the middle of the inner reinforcing rib part 3, and the through hole 5 is located above the recessed reinforcing rib 6. The through hole 5 of this structure can exhaust the reinforcing plate body 1 as a whole during the welding process on the car body, avoiding the gas generated by welding from escaping and causing welding defects. At the same time, it can also reduce the shrinkage stress of the welding heat affected zone to a certain extent. A number of horizontal reinforcing ribs 7 are provided on the inner reinforcing rib part 3 and the outer reinforcing rib part 4. The horizontal reinforcing ribs 7 of the structure can reinforce the inner reinforcing ribs 3 and the outer reinforcing ribs 4 to improve the strength of the inner reinforcing ribs 3 and the outer reinforcing ribs 4. The connection between the connecting part 2 and the inner reinforcing ribs 3 and the outer reinforcing ribs 4 is provided with vertical reinforcing ribs 10. The vertical reinforcing ribs 10 of this structure can reinforce the connection between the connecting part 2 and the inner reinforcing ribs 3 and the outer reinforcing ribs 4 to improve the overall strength of the reinforcing plate body 1. Notches are provided at the upper and lower ends of the outer edge of the inner reinforcing rib 3. The notches on the outer edge of the inner reinforcing rib 3 of this structure can reduce the weight. Under the premise of ensuring the structural strength, the material consumption of the reinforcing plate body 1 can be reduced, thereby achieving the purpose of lightweighting. The edge of the outer end of the outer reinforcing rib 4 is provided with a curved edge.The curved edge of the outer end of the outer reinforcing rib 4 extends inward to form an arc-shaped surface. The curved edge of the outer end of the outer reinforcing rib 4 of this structure can better adapt to the complex space structure in the interior space of the car to avoid affecting the layout of other structures. The width of the outer reinforcing rib 4 is greater than the sum of the widths of the connecting portion 2 and the inner reinforcing rib 3. The outer reinforcing rib 4 of this structure enlarges the entire reinforcing plate body 1 to ensure the number of welding points with the car body.

[0023] Working principle: When using the lock buckle installation point reinforcement plate structure, firstly, the reinforcement plate body 1 is multi-point welded through the connection part 2, the inner reinforcing rib part 3 and the inner side of the outer reinforcing rib part 4 to the corresponding position on the vehicle body. During the welding process of the reinforcement plate body 1 as a whole, the through hole 5 can cooperate to exhaust the smoke generated during the welding process of the reinforcement plate body 1. When the reinforcement plate body 1 is welded as a whole, the horizontal reinforcing ribs 7 and the vertical reinforcing ribs 10 can strengthen the reinforcement plate body 1 as a whole to ensure its structural strength, and then use the two lock buckle installation points 9 to cooperate with the installation of the lock buckle. At the same time, the bolt hole 8 can also cooperate with the inserted bolt fixing part to further stabilize the lock buckle during installation. When the lock buckle is installed, the nest-shaped reinforcing rib 6 will also strengthen the position where the reinforcement plate body 1 contacts the lock buckle to ensure the strength of this position and not easily deform. In this way, the door lock buckle can be firmly installed on the corresponding position on the vehicle body through the reinforcement plate body 1, thereby completing a series of tasks.
