Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automobile accessories, and particularly relates to a stamping-formed automobile stand column buckle. BACKGROUND

[0002] The automobile stand column is one of A, B and C columns, and inner sides of the automobile stand column need to be installed with pipelines, plastic support plates and interior trim plates and the like. Large-size plastic parts are usually fixed by using an edge buckle. The middle part of the plastic part is usually not constrained. When the edge of the plastic part is subjected to a large pressure, the buckle structure can be loosened to cause the part to fall off. SUMMARY

[0003] The application aims to provide a buckle which can buckle the middle part of a plastic part with an automobile stand column.

[0004] To achieve the above object, the application provides a stamping-formed automobile stand column buckle. The automobile stand column buckle comprises a flat inserting plate. The flat inserting plate is formed by stamping to form a pair of elastic frames and a pair of limiting buckles. After the flat inserting plate is formed by stamping to form two elastic frames, a giving-in groove is formed in the inside. The lower ends of the two elastic frames are connected with the inner bottom surface of the giving-in groove. The projections of the two elastic frames in the front-rear direction are left-right symmetrical. The two limiting buckles are located on the outer top surface of the flat inserting plate. The projections of the two limiting buckles in the front-rear direction are left-right symmetrical. The projection of the elastic frame in the up-down direction intersects with the projection of the limiting buckle in the up-down direction only at the projection of the flat inserting plate in the up-down direction. In this way, the center of the whole automobile stand column buckle is relatively close to the geometric center of the flat inserting plate.

[0005] As a kind of preferred, the elastic frame comprises the inclined support plate connected with the inner bottom surface of the giving-in groove, the inclined support plate gradually moves away from the flat inserting plate upwards, the upper end of the inclined support plate has the flat supporting plate extending to the flat inserting plate, the flat supporting plate opposite to one end of the flat inserting plate has the inner blocking plate extending to the direction of the limiting buckle, for abutting against the inner wall of the automobile stand column mounting hole.

[0006] As a kind of preferred, the flat supporting plate is perpendicular to the flat inserting plate, which is convenient for closely adhering to the inner wall of the automobile stand column.

[0007] As a kind of preferred, the inner blocking plate is parallel to the flat inserting plate, which is convenient for keeping flush with the inner wall of the automobile stand column mounting hole.

[0008] As a kind of preferred, the circular arc is transitioned between the inclined support plate and the flat supporting plate, the elastic frame is provided with the pressure relief groove at the circular arc transition of the inclined support plate and the flat supporting plate, so that the circular arc transition of the elastic frame is more easily deformed.

[0009] As a kind of preferred, the limiting buckle is perpendicular to the flat inserting plate and parallel to the outer surface of the plastic part.

[0010] As a preferred, the side of the limiting plate has a clamping strip, which is opposite to the direction of the elastic frame, and is used to clamp the clamping groove in the mounting groove of the outer surface of the plastic part.

[0011] As a preferred, the clamping strip is parallel to the flat insertion plate, can hook the clamping groove in the mounting groove, and avoid the edge of the limiting plate from being raised.

[0012] Compared with the prior art, the application has the following beneficial effects:

[0013] (1) By designing the tapered elastic frame and the parallel clamping plate structure, the elastic frame can pass through the through hole of the plastic part and the mounting hole of the automobile column by using its elasticity, and the elastic frame is constrained on the inner wall of the automobile column after expansion, and the limiting plate is constrained on the outside of the plastic part, which well connects the middle part of the plastic part and the automobile column, and even if the edge of the plastic part is separated from the automobile column, the automobile column buckle can well constrain the plastic part on the inside of the automobile column.

[0014] (2) By stamping, the positions of the elastic frame and the limiting frame are reasonably arranged, so that the material distribution of the entire column buckle is more uniform, and it is not easy to bend to one side, and the stress balance degree and stability will be better.

[0025] like Figures 1-5 The stamped automotive pillar buckle shown includes a flat insert plate 1. The flat insert plate 1 is stamped to form a pair of elastic frames 2 and a pair of limiting plates 3. The flat insert plate 1 is aligned with the alloy sheet before stamping. After the flat insert plate 1 is stamped to form two elastic frames 2, a relief groove 101 is formed inside. The lower ends of the two elastic frames 2 are connected to the inner bottom surface of the relief groove 101. The two elastic frames 2 are the material that originally filled the relief groove 101. The elastic frame 2 includes a diagonal support plate 201 connected to the inner bottom surface of the relief groove 101. The diagonal support plate 201 is a flat plate that gradually moves upward away from the flat insert plate 1. Therefore, the projection of the two diagonal support plates 201 in the front-rear direction forms an inverted cone shape. The upper end of the diagonal support plate 201 has a flat support plate 202 extending towards the flat insert plate 1.

[0026] Two limiting clamping plates 3 are located on the outer top surface of the flat insertion plate 1, the flat supporting plate 202 has an inner blocking plate 203 extending in the direction of the limiting clamping plate 3 at one end opposite to the flat insertion plate 1, the flat supporting plate 202 is perpendicular to the flat insertion plate 1, the inner blocking plate 203 is parallel to the flat insertion plate 1, the circular arc transition between the inclined supporting plate 201 and the flat supporting plate 202, and the elastic frame 2 is provided with a pressure reduction groove 204 at the circular arc transition of the inclined supporting plate 201 and the flat supporting plate 202, because the material at the circular arc transition is reduced, the circular arc transition is more easily elastically deformed.

[0027] The limiting clamping plate 3 is perpendicular to the flat insertion plate 1, and the limiting clamping plate 3 has a clamping strip 301 on one side of the flat insertion plate 1, the clamping strip 301 is opposite to the direction of the elastic frame 2, and the clamping strip 301 is also parallel to the flat insertion plate 1, and both are formed by stamping and bending.

[0028] It should be noted that the projections of the two elastic frames 2 in the front-rear direction are left-right symmetrical, the projections of the two limiting clamping plates 3 in the front-rear direction are left-right symmetrical, the projection of the elastic frame 2 in the up-down direction intersects with the projection of the limiting clamping plate 3 in the up-down direction only at the projection of the flat insertion plate 1 in the up-down direction, that is, the directions of the two elastic frames 2 protruding from the flat insertion plate 1 are staggered with the directions of the two limiting clamping plates 3 protruding from the elastic frame 2.

[0029] Working principle: when in use, first, the edge of the plastic part to be installed in the vehicle column is clamped with the vehicle column, then the lower end of the flat insertion plate 1 is inserted into the through hole provided in the middle of the plastic part, the through hole on the plastic part is aligned with the mounting hole on the vehicle column, the outer surface of the plastic part also has a groove continuous with the through hole, the two inclined supporting plates 201 will resist the inner wall of the through hole and gradually shrink until the two flat supporting plates 202 are inserted into the mounting hole on the vehicle column, the two inclined supporting plates 201 will instantaneously release the elastic force, support the two inner blocking plates 203, and tightly adhere to the inner wall of the mounting hole of the vehicle column, and the flat supporting plate 202 is supported on the inner wall of the vehicle column, at this time, the two flat supporting plates 202 are embedded in the groove on the outer surface of the plastic part, the clamping strip 301 is engaged with the clamping groove in the groove, and the vehicle column buckle can well ensure the stability of the connection between the middle of the plastic part and the vehicle column, even if the edge of the plastic part is separated from the vehicle column, the middle part can also maintain the connection;

[0030] When the vehicle column buckle needs to be removed, a pair of pliers is needed to be inserted into the vehicle column, the two inclined supporting plates 201 are brought close to each other until the two flat supporting plates 202 are squeezed into the mounting hole, and finally the lower end of the flat insertion plate 1 is pushed, so that the flat supporting plate 202 can be pulled out of the mounting hole, and after the plastic part is removed, it is more simple to pull out the flat supporting plate 202 from the through hole.

[0031] The foregoing describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments, and the above-described embodiments and descriptions in the specification are only the principles of the present application.
