Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, and in particular to an anti-dropping locking mechanism for an A-pillar of an automobile interior decoration part. Background Art

[0002] The A-pillar of the car interior refers to the structural parts located on both sides of the front seats of the car, extending from the front windshield down to the door frame. It is an important part of the car body and is crucial to ensuring the structural strength of the vehicle and the safety of the passengers.

[0003] The A-pillar of an automobile interior is usually made of multiple layers of high-strength steel or aluminum alloy and other materials. The stacked multi-layer plates are usually connected by welding. However, when the multi-layer plates are only connected by welding, the welding points are prone to collapse when the A-pillar is hit by a strong external force, resulting in separation of the multi-layer plates. In addition, the A-pillar's anti-deformation ability can only be provided by a specific shape and structure, which reduces the A-pillar's anti-deformation performance. Summary of the invention

The support rods 12 on the front and rear sides are distributed in an inverted "X" shape, and a plurality of evenly distributed threaded sleeves 14 are installed on the horizontal inner end surface of the skin plate 11.

[0032] See also Figure 1 , Figure 5 and Figure 8 The support unit 2 includes an inner support plate 21 fitted with the skin plate 11, a protrusion with an isosceles trapezoidal cross-section is arranged in the middle of the inner support plate 21, a plurality of evenly distributed plug-in plates 22 are installed through the horizontal section of the protrusion in the middle of the inner support plate 21, a cylindrical through hole for slidingly connecting the threaded sleeve 14 is opened in the middle of the vertical section of the plug-in plate 22, and a plurality of evenly distributed placement openings 23 are opened at the front and rear corners of the protrusion in the middle of the inner support plate 21.

[0033] See also Figure 5 A triangular protrusion 121 is integrally formed at the lower end of the support rod 12 , and the triangular protrusion 121 is closely attached to the outer surface of the raised hypotenuse in the middle of the inner support plate 21 .

[0034] During the specific work, the inner support plate 21 is selected and moved toward the skin plate 11 until the protrusion of the inner support plate 21 is in close contact with the horizontal inner end surface of the skin plate 11, and the cylindrical through hole of the plug-in plate 22 is plugged into the corresponding threaded sleeve 14. At the same time, multiple support rods 12 pass through the corresponding placement openings 23 and move to the corresponding sides of the plug-in plates 22. The opposite ends of the multiple support rods 12 on the front and rear sides are in close contact with the corresponding multiple plug-in plates 22. The plug-in plates 22 support the support rods 12, and the triangular protrusion 121 is in close contact with the outer surface of the oblique edge of the protrusion in the middle of the inner support plate 21. The two work together to effectively improve the impact resistance of the bending part of the skin plate 11, thereby improving the use strength of the A-pillar of the automobile.

[0035] See also Figure 5 and Figure 6 The support rod 12 has one end away from the skin plate 11 and is integrally formed with a rectangular plate 13 with a plug-in hole in the middle. The rectangular plate 13 is located at the upper end of the horizontal section of the plug-in plate 22, and the plug-in hole is coaxial with the connecting hole opened in the plug-in plate 22.

The upper end of the U-shaped baffle 252 is provided with an inclined surface.

[0037] During specific operation, when the protrusion of the inner support plate 21 is in close contact with the horizontal inner end surface of the skin plate 11, the plug-in plate 22 drives the U-shaped baffles 252 on both sides to move toward the corresponding two rectangular plates 13. After the inclined surface on the U-shaped baffle 252 contacts the rectangular plate 13, the force drives the U-shaped baffle 252 to shrink into the limiting countersunk hole 251 and squeeze the reset spring 253. The plug-in plate 22 continues to drive the two U-shaped baffles 252 to move to the upper end of the rectangular plate 13. The rectangular plate 13 releases the obstruction of the U-shaped baffle 252, and the reset spring 253 resets and drives the U-shaped baffle 252 to move to the upper end of the rectangular plate 13.
