Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a splicing structure of an interior trim panel under an automobile pillar. Background Art

[0002] In the automotive industry, the quality of the splicing between the A-pillar lower interior panel and the front door sill interior panel is directly related to the appearance of the vehicle and the noise level during driving. Traditionally, the splicing of these two parts of the interior panel mainly relies on multiple bolts for fastening. However, this traditional bolt connection method often has a series of problems after long-term use;

[0003] First, bolts are prone to rust after long-term use, especially in humid or corrosive environments. Rust not only affects the aesthetics of the bolts, but more importantly, it weakens their fastening force, causing the connection between the interior panels to become unstable. This instability may cause loosening and abnormal noise between the interior panels, giving passengers a bad riding experience. Secondly, even if there is no rust, the bolts will gradually loosen due to vibration and impact during long-term use. This loosening will also cause the connection between the interior panels to become unstable, resulting in abnormal noise or safety hazards. Especially when driving at high speeds or on bumpy roads, the loosening of the bolts may be more obvious, which will have an adverse effect on the driving stability of the vehicle. Therefore, we propose a splicing structure for the interior panels under the car pillars to solve the above problems. Utility Model Content

Both sides of the mounting groove 13 are open. Move the shift block 12, the shift block 12 slides on the guide rod 6 and stretches the second spring 15. At the same time, the shift block 12 drives the corresponding hinge rod 8 to move, and the hinge rod 8 drives the corresponding latch 10 to move, so that the latch 10 slides on the corresponding fixing rod 9 and compresses the first spring 11. Then, the limiting rod 17 on the lower interior panel 3 of the automobile column is inserted into the corresponding limiting groove 16. When the bottom of the lower interior panel 3 of the automobile column contacts the top of the door frame interior panel 2, the force on the shift block 12 is relaxed at this time, and the first spring 11 in the compressed state is reset. Under the action of the automatic elastic force of the first spring 11, the first spring 11 drives the corresponding latch 10 to be clamped with the slot 14, so that the lower interior panel 3 of the automobile column and the door frame interior panel 2 are fixed. No bolts are used, and there will be no loosening or rusting, thereby improving the stability between the two.

[0024] like Figure 3 As shown, in some embodiments, two second springs 15 are welded between the bottom of the moving block 7 and the bottom inner wall of the fixed box 4.
