[0002] In the past, door frame trim panels were generally injection molded with engineering plastics such as ABS, ASA or PC+ABS, and then treated with high-gloss paint on the surface to achieve a high-gloss black effect. However, the painted trim panels often have orange peel and mirror frame effect appearance defects, and it is difficult to achieve the perfect effect of piano lacquer. At the same time, the coating process is not environmentally friendly. However, the door frame trim panel solution made of plexiglass PMMA material can eliminate the coating process, thus bringing significant cost advantages.

[0003] The trim panel body is made of plexiglass PMMA material, which can achieve a high-gloss black effect without painting, and the appearance can achieve the perfect effect of piano paint. However, the performance of plexiglass PMMA material is relatively brittle, and the elongation at break is only 5%, while the elongation at break of general engineering plastics is about 30%. This leads to abnormal noise problems caused by the cooperation between the door frame trim panel body made of plexiglass PMMA material and the sheet metal, and the abnormal noise is also easy to amplify the loudness.

[0004] In order to solve the above problems, a new connection structure needs to be designed. Summary of the invention

[0030] In the technical solution, there are three matching surfaces in the inner ring of the buckle 2 and the outer ring of the buckle seat 1. The first matching bevel 10, the second matching bevel 11 and the third matching bevel 14 support the first fitting surface 19, the second fitting surface 16 and the third fitting surface 18 on the buckle seat 1, so that the two are firmly connected and there is no abnormal sound from the product when vibration occurs. At the same time, the buckle ear 7 locks the buckle seat 1 to ensure the assembly speed, while reducing the assembly cost of the sheet metal 3 and the door frame trim 4, and avoiding the abnormal sound problem caused by the door frame trim 4 made of plexiglass PMMA and the sheet metal 3 during assembly.

[0031] As a supplement to the present technical solution, matching ribs 12 are provided at the front ends of the left and right hollow sides of the buckle 2 , and a first matching inclined surface 15 corresponding to the matching ribs 12 is provided on the buckle seat 1 .

[0032] By providing the matching rib 12, the buckle 2 is positioned and inserted into the buckle seat 1, thereby improving the degree of fit between the two.

[0033] As a supplement to the present technical solution, front positioning ribs 21 are provided on both sides of the front end of the buckle seat 1, and a downward extending fitting slope 17 is provided on the outer side of the front positioning rib 21, and a second matching inclined slope 13 corresponding to the fitting slope 17 is provided on the buckle 2.

[0034] In the present technical solution, the fitting bevel 17 and the second matching inclined bevel 13 are matched and aligned, so that the front positioning rib 21 can laterally position the entire buckle 2, which facilitates the fastening of the buckle 2 and avoids the buckle 2 from deflecting.

[0035] As a supplement to the present technical solution, the lower end of the front positioning rib 21 extends horizontally along the upper end surface of the door frame trim 4, and transverse supporting ribs 24 matching the horizontal extension of the front positioning rib 21 are provided on both sides of the rear of the buckle seat 1.

[0036] As a supplement to the present technical solution, support feet 8 for blocking the sheet metal 3 are arranged on both sides of the rear of the buckle 2.

[0037] By providing the horizontal extension of the front positioning rib 21, the transverse supporting rib 24 and the supporting foot 8, the support of the buckle seat 1 to the buckle 2 is achieved, thereby ensuring that the sheet metal 3 will not come into direct contact with the door frame trim 4, avoiding abnormal assembly noise between the two, and allowing the force of pressing the door frame trim body by hand in the whole vehicle state to be transmitted to the buckle, and then to the sheet metal, avoiding sagging during the pressing process.

[0038] As a supplement to the present technical solution, arrow grooves 9 are provided on one side of the buckle 2 and on the end surface of the door frame trim 4.

[0039] In the present technical solution, during the assembly process, it is necessary to ensure that the direction of the arrow in the arrow groove 9 remains consistent before assembly can be performed. This structure facilitates the workers to align the buckle 2 and the buckle seat 1, thereby ensuring that the two are quickly matched and installed.

[0040] As a supplement to the present technical solution, assembly slopes 5 are provided at the left and right parts of the upper end of the buckle 2 , and gaps 6 are provided between the two sides of the buckle 2 and the sheet metal 3 .

[0041] In this technical solution, the buckle 2 and the sheet metal 3 are arranged in cooperation to form a gap 6 of 0.1 mm, which can accommodate the thickness of the paint. Even if the size of the gap 6 fluctuates slightly during the assembly process, it can still complete its work. Within the straight line range of the entire gap 6, it can maintain 0.1 mm. The positioning is not affected by the ups and downs of the parts of the assembly batch and assembly method, and the positioning function is more guaranteed. At the same time, the gap 6 is in direct contact with the sheet metal, avoiding the abnormal sound problem caused by the door frame trim 4 made of organic glass PMMA material and the sheet metal 3.

[0042] As a supplement to the present technical solution, the end of the buckle ear 7 is provided with a curved surface structure 22 matching the front and rear side edges of the buckle seat 1 .

[0043] In the present technical solution, the arc surface structure 22 is used to increase the snapping sound when the snapping ear 7 is snapped. By increasing the length a of the arc surface structure 22, the snapping part of the snap seat 1 needs to travel a longer distance to connect with the snapping ear 7. The longer the distance, the greater the acceleration thereof, thereby ensuring the snapping force between the snapping ear 7 and the snap seat 1, thereby enhancing the snapping sound and making the sound serve as a reminder, so that workers can hear the reminder sound when the snapping is in place even in a noisy working environment.

[0044] As a supplement to the present technical solution, a step groove 23 is provided at the root of the arc surface structure 22 .

[0045] In the present technical solution, a step groove 23 is provided so that the buckle portion of the buckle seat 1 is in a suspended state at one end during the rebound process, thereby improving the buckle force of the rebound and making a stronger sound after the buckle seat 1 is buckled into place, which facilitates workers to judge whether the buckle 2 is in place in a noisy working environment.

[0046] As a supplement to the present technical solution, limiting steps 20 are provided at the rear of the left and right sides of the interior of the buckle 2 .

[0047] In the present technical solution, a limiting step 20 is provided to ensure the alignment of the buckle 2, thereby preventing the buckle 2 and the buckle seat 1 from being offset, thereby improving the firmness of the two.

[0048] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the described specific embodiments or replace them in a similar manner without departing from the scope defined by the spirit of the present invention.
