Abstract
The utility model relates to a reinforcing plate at the lower section of an inner plate of an A column of an automobile, which comprises a reinforcing plate body, wherein the middle part of the reinforcing plate body is of an arch structure, the top surface of the arch structure is provided with round holes sleeved on a convex column of the inner plate of the A column, two bottom edges of the arch structure are respectively provided with a first bending edge which extends outwards and is used for being attached to the inner plate of the A column, two longitudinal sides of the arch structure are respectively provided with a second bending edge which is upwards and is used for being attached to the inner plate of the A column, and the first bending edge and the second bending edge are respectively provided with an upper concave convex arch platform which is used for being attached and welded with the inner plate of the A column. According to the utility model, the bosses used for bonding and welding with the A-pillar inner plate are respectively arranged on the first bending edge and the second bending edge of the lower reinforcing plate, so that the lower reinforcing plate and the A-pillar inner plate only need to be partially bonded and then are in spot welding connection, the bonding of the lower reinforcing plate and the A-pillar inner plate is easier to ensure and strengthen the connection firmness and the integral strength of the lower reinforcing plate and the A-pillar inner plate, the manufacturing difficulty of parts is reduced, and the welding size of the parts is convenient to adjust.
Description
Technical Field
The utility model relates to a reinforcing plate for the lower section of an automobile A column inner plate.
Background
The A column of the automobile is a connecting column for connecting the roof and the front cabin at the left front and the right front, is positioned in the front area of the whole cabin structure and provides support for the automobile body structure. The a-pillar structure generally includes an a-pillar reinforcement plate and an a-pillar inner panel, wherein the a-pillar inner panel lower reinforcement plate is welded inside the a-pillar inner panel, and is connected to the a-pillar inner panel by spot welding, thereby increasing the strength of the a-pillar inner panel. At present, the lower reinforcing plate is integrally attached to the A-pillar inner plate, the attaching surfaces of the lower reinforcing plate and the A-pillar inner plate are guaranteed to be completely consistent in production, the process requirements are very high, and the processing and manufacturing difficulty is increased. The shape of the joint surfaces of two parts is not very same, so that the joint performance of the two parts is poor, and especially the joint performance of the welding position is poor, the welding combination degree is affected, and the structural strength of the A column is further affected.
Disclosure of Invention
The utility model aims to solve the problem of providing the lower reinforcing plate of the inner plate of the automobile A column, and the welding joint surface of the lower reinforcing plate is easy to adjust, so that the manufacturing difficulty of parts is reduced, and the welding size of the parts is convenient to adjust.
The technical scheme provided by the utility model is as follows: the utility model provides an automobile A post inner panel hypomere reinforcing plate, includes the reinforcing plate body, the reinforcing plate body middle part is arch structure, and arch structure's top surface is provided with the round hole that is used for the cover to locate A post inner panel projection, and arch structure's two base have respectively to outside the extension be used for with A post inner panel laminating bend limit one, arch structure vertical both sides have respectively ascending be used for with A post inner panel laminating bend limit two, bend limit one and bend and all be equipped with on limit two be used for with A post inner panel laminating welded concave up convex arch platform down.
The arch apex angle of the arch structure is an arc-shaped chamfer angle.
And the second bending edge is provided with a mounting nut.
According to the utility model, the bosses used for bonding and welding with the A-pillar inner plate are respectively arranged on the first bending edge and the second bending edge of the lower reinforcing plate, so that the lower reinforcing plate and the A-pillar inner plate only need to be partially bonded and then are in spot welding connection, the bonding of the lower reinforcing plate and the A-pillar inner plate is easier to ensure and strengthen the connection firmness and the integral strength of the lower reinforcing plate and the A-pillar inner plate, the manufacturing difficulty of parts is reduced, and the welding size of the parts is convenient to adjust.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Detailed Description
Referring to fig. 1, the utility model comprises a reinforcing plate body 1, wherein the middle part of the reinforcing plate body 1 is provided with an arch structure 6, the top surface of the arch structure 6 is provided with a round hole 5 which is sleeved on an A column inner plate convex column, two bottom edges of the arch structure 6 are respectively provided with a first bending edge 2 which extends outwards and is used for being attached to the A column inner plate, two longitudinal sides of the arch structure 6 are respectively provided with a second bending edge 4 which is upwards used for being attached to the A column inner plate, and the first bending edge 2 and the second bending edge 4 are respectively provided with an upper concave convex arch platform 3 (namely, the cross section of the upper concave convex arch platform is a Chinese character 'ji' -shaped boss) which is used for being attached and welded with the A column inner plate.
The arch structure 6 is sleeved on the arch convex surface of the inner plate of the A column, and the arch apex angle of the arch structure 6 is an arc-shaped chamfer 8 so as to increase the attaching area of the corner.
And the second bending edge 4 is provided with a mounting nut 7.
The upper concave convex arch abutment is about 3mm high, so that the lower reinforcing plate only needs to be in spot welding connection after the local surface is attached to the A-pillar inner plate. Therefore, the welding joint surface of the part is easy to adjust, the manufacturing difficulty of the part is reduced, and the welding size of the part is more convenient to adjust. In addition, the integral strength of the part is also enhanced after the boss is added.
