[0056] The present invention is further described below in conjunction with embodiments and drawings.

[0057] like Figures 1 to 3As shown, a vehicle body side skirt includes a strip-shaped side skirt body 100, and the side skirt body 100 includes a strip-shaped upper body 110 and a lower body 120, wherein the upper body 110 and the lower body 120 are integrally formed, wherein the outer side surface of the upper body 110 is a smooth surface, and the outer side surface of the lower body 120 is a leather grain surface. A smooth surface refers to a smooth surface with a relatively low roughness that can be achieved by a workpiece under processing conditions, and is distinguished from a surface with convex or concave grains. The connection between the upper body 110 and the lower body 120 is concave to form a groove 130, and the groove 130 is arranged along the length direction of the side skirt body 100, and a decorative strip 200 adapted thereto is detachably arranged in the groove 130. The outer side surface of the decorative strip 200 smoothly transitions with the lower edge of the outer side surface of the upper body 110 and the upper edge of the outer side surface of the lower body 120.

[0058] like Figure 1 The two ends of the groove 130 gradually narrow and extend to the corresponding ends of the side skirt body 100 to form a slit groove 140, and the depth of the slit groove 140 is less than the depth of the groove 130. In this embodiment, the width and depth of the slit groove 140 are both 2 mm.

[0059] like Figure 6 At least two first reinforcing plates 132 are vertically arranged on the bottom of the groove 130, all of which are distributed along the length direction of the groove 130, the plate surface of the first reinforcing plates 132 is located in the vertical direction, and the upper and lower edges of at least one first reinforcing plate 132 are respectively close to the corresponding groove wall of the groove 130. The decorative strip 200 is in the shape of a groove with an opening inward, the upper edge of the decorative strip 200 is inserted between the first reinforcing plate 132 and the upper groove wall of the groove 130, and the lower edge of the decorative strip 200 is inserted between the first reinforcing plate 132 and the lower groove wall of the groove 130. In this way, at least one first reinforcing plate 132 is located in the notch of the decorative strip 200, and its upper and lower edges respectively support the upper and lower edges of the decorative strip 200.

[0060] A plug-in structure and an anti-drop connection structure are provided between the inner side surface of the decorative strip 200 and the groove 130 .

[0061] The first reinforcing plate 132 not only strengthens the bottom of the groove 130, but also supports the decorative strip 200 from the notch, thereby enhancing its rigidity and bearing pressure. The decorative strip 200 and the side skirt body 100 are connected firmly in all directions through the plug-in structure and the anti-slip connection structure.

[0062] like Figures 3 to 5The plug-in structure includes a plug-in plate 210 and an insertion slot 131. The plug-in plate 210 is fixedly arranged on the inner side of the decorative strip 200. The plug-in plate 210 is rectangular. An anti-slipping protrusion 211 is arranged in the inner hole of the plug-in plate 210. The anti-slipping protrusion 211 is fixedly connected to the front end of the plug-in plate 210. The anti-slipping protrusion 211 protrudes to one side of the plug-in plate 210. The other side surface of the plug-in plate 210 is provided with a plug-in plate rib 212. The plug-in plate rib 212 is arranged along the insertion direction of the plug-in plate 210. The thickness of the anti-slipping protrusion 211 and the height of the plug-in plate rib 212 both gradually increase from the front end of the plug-in plate 210 to the rear end of the plug-in plate 210. The insertion slot 131 is opened on the bottom of the groove 130, and the plug-in plate 210 is inserted in the insertion slot 131. After the front end of the inserting plate 210 passes through the inserting slit 131 , the anti-dropping protrusion 211 abuts against the bottom of the groove 130 from the inner side of the side skirt body 100 .

[0063] like Figure 3 , 7 As shown in Figure 8, in order to make the decorative strip 200 fit closely with the groove 130, two rows of insertion slots 131 are provided at the bottom of the groove 130, and the two rows of insertion slots 131 are distributed up and down, each row of the insertion slots 131 has at least two insertion slots 131, and the insertion slots 131 in the same row are distributed along the length direction of the groove 130. Two rows of plug plates 210 are provided on the inner side of the decorative strip 200, and the plug plates 210 correspond to the insertion slots 131 one by one, and the two side surfaces of the plug plates 210 face the upper side and the lower side of the decorative strip 200 respectively.

[0064] like Figure 3 , wherein the upper surface of the plugboard 210 in the upper row abuts against the upper edge of the inner hole of the corresponding insertion slot 131, the plugboard ribs 212 on the plugboard 210 in the upper row abut against the lower edge of the inner hole of the corresponding insertion slot 131, and the anti-slip protrusions 211 on the plugboard 210 in the upper row protrude upward; the lower surface of the plugboard 210 in the lower row abuts against the lower edge of the inner hole of the corresponding insertion slot 131, the anti-slip protrusions 211 on the plugboard 210 in the lower row protrude downward, and the plugboard ribs 212 on the plugboard 210 in the lower row abut against the upper edge of the inner hole of the corresponding insertion slot 131. In the length direction of the decorative strip 200, the protrusion directions of the anti-slip protrusions 211 on any two adjacent plugboards 210 are opposite.

[0065] When the plug board 210 is inserted into the slot 131, the plug board 210 itself and the anti-slip protrusion 211 on the plug board 210 are elastically deformed to allow the plug board 210 to enter, and then the anti-slip protrusion 211 passes through the slot 131 and recovers its deformation, thereby playing a role of preventing reverse movement. At this time, since the thicker part of the plug board rib 212 is located in the slot 131, it plays a role of stabilizing the plug board 210 and preventing it from deforming toward the plug board rib 212, further enhancing the anti-slip effect. The upper and lower rows of plug boards 210 respectively abut against the upper and lower edges of the corresponding inner holes of the slot 131, so that the upper and lower rows of plug boards 210 are overall interference fit with the groove 130, enhancing the anti-slip effect.

[0066] In order to stabilize the installation positions of the upper and lower sides of the decorative strip 200 , at least two inserting plates 210 are respectively connected to the upper and lower sides of the decorative strip 200 .

[0067] like Figure 4 and 9 As shown, in order to improve the rigidity of the decorative strip 200, at least two second reinforcing plates 222 are arranged inside the decorative strip 200. The second reinforcing plates 222 are spaced apart along the length direction of the decorative strip 200, and the second reinforcing plates 222 are connected to the groove wall and groove bottom of the decorative strip 200. Each second reinforcing plate 222 is also connected to a reinforcing enclosure 221, and all the reinforcing enclosures 221 are located on the same side of the second reinforcing plate 222, and the two sides of the reinforcing enclosure 221 face the decorative strip 200 and the groove 130 respectively. The reinforcing enclosure 221 is connected to the corresponding second reinforcing plate 222 and the upper and lower sides of the decorative strip 200, thereby forming a box-shaped reinforcing structure 220 with an opening, and the openings of all the box-shaped reinforcing structures 220 face the same end of the decorative strip 200, so as to facilitate molding and demoulding. The box-shaped reinforcing structure 220 and the first reinforcing plate 132 are staggered with each other.

[0068] like Figure 4 and 9 As shown, in order to improve the bottom rigidity of the groove 130, the bottom of the groove 130 is bent toward both sides thereof to form reinforcing ribs 136 extending along the length direction of the groove 130. The bottom of the groove 130 is offset inwards corresponding to each of the box-shaped reinforcing structures 220 to form a first reinforcing recess 133. At least one of the plug plates 210 is fixedly disposed on the reinforcing enclosure 221, and the matching plug slots 131 are opened at the corresponding locations of the first reinforcing recesses 133.

[0069] like Figure 4 and 9As shown, the anti-detachment connection structure includes a connection column 230 fixedly arranged on the inner side of the decorative strip 200, one end of the connection column 230 is connected to the decorative strip 200, and the other end extends toward the groove 130 and abuts against the bottom of the groove 130, and a third reinforcing plate 231 is connected between the outer wall of the connection column 230 and the decorative strip 200.
