Figure 1 is a sectional view of a car roof. Fig. 2 is a schematic cross-sectional view of the decorative strip in Fig. 1; Fig. 3 is a schematic cross-sectional view of the installation groove in Fig. 1 . What needs to be explained here is that Figure 2 and Figure 3 are just schematic diagrams, and do not limit the cross-section of the decorative strip and the cross-section of the installation groove to be exactly the same as the illustrations, and only need to be roughly consistent with the diagrams in actual production. .

The car roof 1 as shown in FIGS. 1 to 3 includes: a roof panel 20 , a side panel 30 and a decorative strip 10 , and a mounting groove 40 is formed at the joint of the roof panel 20 and the side panel 30 . The decorative strip 10 includes: an overlapping portion 110 and a clamping portion 120, the overlapping portion 110 is overlapped on the boss 50 formed on the top of the mounting groove 40, the shape of the clamping portion 120 matches the shape of the inner wall of the mounting groove 40 and There is an interference fit between the installation groove 40 and the clamping portion 120 . The cross section of the clamping portion 120 is trapezoidal, the left side 1201 of the trapezoid and the lower bottom 1203 form an acute angle, and the left side of the corresponding mounting groove 40 forms a concave portion 410 matching the acute angle, that is, A concave portion 410 matching the acute angle is formed on the lapped side of the side panel 30 to the left. Of course, it is also possible to form an acute angle between the right side 1202 and the lower bottom 1203 of the trapezoid. Correspondingly, a concave portion 410 matching the acute angle is formed on the right side of the mounting groove 40, that is, on the upper cover plate A concave portion 410 matching the acute angle is formed by indenting to the right side on the overlapping edge of the .

In the car roof 1 of this embodiment, the overlapping portion 110 of the decorative strip 10 is overlapped on the boss 50 formed on the top of the installation groove 40, and the clamping portion 120 of the decorative strip 10 is clamped on the top of the installation groove 40. The method makes it no longer necessary to apply glue or weld studs in advance during installation of the decorative strip 10, thereby simplifying the assembly process, reducing the difficulty of assembly, and improving assembly efficiency. Moreover, the clamping portion 120 of the decorative strip 10 is interference-fitted with the installation groove 40 , which can improve the connection firmness between the decorative strip 10 and the installation groove 40 and prevent the decorative strip 10 from falling off from the installation groove 40 . Moreover, since the profiles of the decorative strip 10 and the mounting groove 40 are matched with each other, the inner wall of the mounting groove 40 will exert downward pressure on the side edge forming an acute angle with the lower bottom edge 1203 in the trapezoidal cross-section of the clamping portion 120 , This further increases the clamping effect between the decorative strip 10 and the installation groove 40 , preventing the decorative strip 10 from falling off from the installation groove 40 .

Specifically, the decorative strip 10 can be made of a material with relatively good elasticity, so that in the process of interference fitting with the installation groove 40, the gap between the inner walls on both sides of the installation groove 40 can be reduced through the appropriate elastic deformation of the material and the decorative strip can be improved. The frictional force between the decorative strip 10 and the installation groove 40 enhances the clamping effect between the decorative strip 10 and the installation groove 40 to prevent the decorative strip 10 from falling off.

Further, when the left side 1201 and the lower base 1203 of the trapezoidal cross-section of the clamping portion 120 form an acute angle, the right side 1202 and the lower base 1203 of the trapezoidal cross-section may form a right angle. Certainly, correspondingly, when the right side 1202 of the trapezoidal cross-section of the clamping portion 120 forms an acute angle with the lower base 1203 , then the left side 1201 of the trapezoidal cross-section of the clamping portion 120 forms a right angle with the lower base 1203 . By forming acute angles and right angles between the two sides of the trapezoidal cross-section of the clamping portion 120 and the lower bottom 1203, it is easier to install the decorative strip 10, and the installation resistance encountered during installation will be smaller. Therefore, the pressing force exerted during installation is reduced, so that labor intensity during assembly can be saved.

The formed lip 1204, for example, can only form one lip 1204 on the left side 1201 or the right side 1202 of the trapezoidal cross section, or can also form a plurality of lips 1204 on the left side 1201 or the right side 1202 . More specifically, the two outwardly protruding lips 1204 formed by the left side 1201 and the right side 1202 can be connected with the midpoints of the upper base and the lower base 1203 (up and down in FIG. 2 ) symmetry. Of course, the two lips 1204 can also be separated by a certain distance in the direction of the center line, for example, the left lip 1204 is closer to the bottom edge 1203 than the right lip 1204 . Further, when the two lips 1204 formed by the left side 1201 and the right side 1202 are symmetrical about the center line of the upper bottom and the lower bottom 1203, the left lip 1204 is located between the left side 1201 and the lower bottom 1203 The right lip 1204 is located at the junction of the right side 1202 and the bottom bottom 1203 .
