Description
Technical Field
The utility model belongs to the technical field of automobile parts, concretely relates to automobile-used lockpin reinforcement and vehicle.
Background
The rear door lock pin reinforcing piece of the automobile is arranged in a C-column cavity of a body-in-white, is L-shaped in structural appearance, is welded with a body side part through spot welding, and is used for supporting a lock pin mounting surface, increasing the strength of the lock pin mounting position and decomposing the door lock opening and closing impact force to the automobile body. In addition, in order to isolate the influence of tire noise of the rear tire on the interior of the vehicle, the expansion rubber block needs to be added in the cavity of the C stand column of the white vehicle body to improve the NVH performance, so that the performance effects of sound insulation and noise reduction are achieved, and the installation support of the expansion rubber block needs to be added in the cavity of the C stand column on the side of the vehicle body to ensure the installation reliability of the expansion rubber block at the position.
According to the traditional technical scheme, as shown in fig. 1 and 2, a lock pin reinforcement 1 is welded on a vehicle body side part 4, an expansion rubber block mounting bracket 111 is welded on the vehicle body side part 4 through spot welding, and an expansion rubber block 3 is clamped on the expansion rubber block mounting bracket 111.
The disadvantages of the conventional technical solutions are mainly reflected in the following two aspects. First, referring to fig. 1, the striker reinforcement 100 is formed in an overall "L" shape including a plane and a vertical surface, and a welding surface 102 is provided at an edge of the plane for welding with the vehicle body-side part 4; and a lock pin mounting hole 101 is formed in the vertical surface and used for mounting a lock pin assembly. Because only one welding surface 102 is connected with the side of the vehicle body, the rigidity and the strength of the bracket are lower, the impact force in the opening and closing process of the vehicle door is completely transmitted and decomposed through the surface, the stress is too concentrated, and the failure is easy to occur. Second, the conventional solution adds an expansion rubber block mounting bracket 111 in the cavity of the C-pillar, i.e. the number of parts is increased. The expansion rubber block mounting bracket 111 is L-shaped and is welded on the vehicle body part 4 through spot welding, and the welding reliability is low.
In conclusion, in the traditional technical scheme, the L-shaped lock pin reinforcing piece is low in strength, and in addition, an expansion rubber block mounting bracket needs to be added, so that the number of vehicle body parts is increased, the welding precision is not well controlled, and the comprehensive cost is high.
Therefore, it is necessary to develop a striker reinforcement for a vehicle and a vehicle.
