Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 5 and 6, the mounting structure of the trim inside the back door of the automobile comprises an upper trim 2, a left trim 3 and a right trim 4 fixed on a metal plate 1 of the back door through a buckle 5, wherein the left end and the right end of the upper trim 2 are arranged in a gradually thinner manner along a direction away from the middle of the upper trim 1, the left end and the right end are 1/2 with a main wall thickness along the wall thickness, and lap joint parts correspondingly matched with the inner side of the upper end of the left trim 3 and the inner side of the upper end of the right trim 4 are respectively formed, namely, the outer sides of the left end and the right end of the upper trim 2 are respectively matched with the inner side of the upper end of the left trim 3 and. Gradually thin setting can reduce 2 tip intensity of upper decoration, and then change and match along with the shape with

left decoration

3 and 4 upper ends of right decoration, make the inboard region of decoration not have obvious clearance, and then has avoidd the left side that current butt joint structure exists, the uneven or too big problem in clearance in right side clearance, the matching quality of upper decoration 2 with left decoration 3 and right decoration 4 has been guaranteed, the requirement to upper decoration 2, the size precision of left decoration 3 and right decoration 4 and the joint hole position precision of back of the body door panel beating 1 has been reduced, make the assembly simple convenient. Referring to fig. 10, the overlapping section 41 at the edge of the upper end of the right decoration 4 is a non-visible surface, and similarly, the overlapping section at the edge of the upper end of the left decoration 4 is also a non-visible surface, so that the non-visible surface pattern area can be gradually eliminated when the dermatoglyph is manufactured, the dermatoglyph area is reduced, and the difficulty in sticking the dermatoglyph is reduced.

Go up ornament 2 and be close to left and right-hand member outside integrated into one piece of overlap joint portion and have joint groove 6, the extension of the 3 upper end outsides of left side decoration and the 4 upper ends outsides of right side decoration be equipped with joint groove 6 corresponds complex joint boss 7. The setting of joint groove 6 and joint boss 7 makes the matching of going up ornament 2 and left decoration 3 and right decoration 4 more reliable and more stable for going up ornament 2 and left decoration 3 and right decoration 4 closely laminate, promoted assembly quality.

Referring to fig. 7, five mounting seats 8 for fixedly connecting the buckles 5 are arranged at intervals on the outer side of the upper decoration 2, one of the mounting seats 8 is located in the middle of the upper decoration 2, the buckles 5 on the mounting seat 8 are correspondingly matched with the positioning holes 11 of the back door metal plate 1, and the buckles 5 on the other four mounting seats 8 are correspondingly matched with the clamping holes 12 of the back door metal plate 1. Through middle part location, both sides fastening, reduced back of the body door panel beating 1's joint hole 12 position accuracy requirement, do benefit to the assembly.

Referring to fig. 8 and 9, mount pad 8 includes roof 81 and U type curb plate 82, roof 81 middle part is equipped with and corresponds joint complex round hole 83 with the annular groove of 5 one ends of buckle, is equipped with the opening 84 at intercommunication round hole 83 and roof 81 border on the roof 81, opening 84 width is less than the round hole 83 diameter, has realized two-way spacing, avoids buckle 5 to drop from mount pad 8, has improved buckle 5's connection reliability. Since the catches on both sides only perform a fastening function, the diameter C of the circular hole in the top plate 81 of the mount 8 located in the middle of the upper garnish 2 is smaller than the diameter D of the circular hole in the top plate 81 of the remaining mount 8.

The openings 84 of the top plates 81 of at least two of the mounting seats 8 are staggered, so that the buckle 5 is prevented from being separated from the mounting seat 8 along the opening 84 due to the movement of the upper decoration 2.

During the assembly, earlier with left decoration 3 and right decoration 4 through the buckle 5 in the outside with the joint hole 12 fastening on the back of the body door panel beating 1, accomplish the assembly of left decoration 3 and right decoration 4. Then, one end of the buckle 5 is installed in the round hole 83 of the installation seat 8 along the opening 84, the other end of the buckle 5 on the middle installation seat 8 is clamped into the positioning hole 11 of the back door metal plate 1, the other ends of the other buckles 5 are clamped into the clamping holes 12 of the back door metal plate 1, the gradually thinned areas at the left end and the right end of the upper decoration 1 are respectively lapped at the inner side of the upper end of the left decoration 3 and the inner side of the upper end of the right decoration 4, the clamping bosses 7 on the left decoration 3 and the right decoration 4 are clamped into the clamping grooves 6 at the end part of the upper decoration 2, and the installation of the automobile back door decoration is completed.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
