The side panel decorative panel body is formed by laser cutting or water jet cutting of the PP honeycomb panel.

[0055] The PP honeycomb panel has a three-layer structure, namely, a surface layer 1, a middle honeycomb layer 2, and a bottom layer 3. The surface layer 1, the middle honeycomb layer 2, and the bottom layer 3 are heated simultaneously to melt the low melting point adhesive layer A, and then the three layers are extruded and bonded together by a composite roller process. After cooling and shaping, a high-strength molded PP honeycomb panel with smooth two sides is obtained.

[0056] The thickness of the side panel body can be selected between 3 mm and 4 mm. In this embodiment, the preferred design thickness is 3.5 mm, which can effectively meet the performance requirements of the product such as bending strength and bending modulus.

[0057] The interior side panel trim has a compression of about 10% after molding. It is relatively strong and firm when connected with clips, and there is no looseness in the side panel trim.

[0058] Since PP honeycomb panels have a hollow structure, they are used in the interior side panel decorative panels of logistics vehicles, which can reduce costs and weight, and reduce the weight of the entire vehicle. Compared with injection molding, the use of PP honeycomb panels does not require mold development, reducing development costs and cycles. When PP honeycomb panels are processed into interior side panel decorative panels, they can be formed through laser cutting or water jet cutting to reduce edge burrs, and no further edge grinding is required, reducing production costs and cycles.

The expansion and clamping arms 44 are used to expand and clamp with the inner plate mounting hole 6 after passing through the inner plate mounting hole, and have a female buckle inner clamping protrusion 45 for preventing the sub-buckle from withdrawing.

[0062] The sub-buckle 5 includes a sub-buckle base 51 and a sub-buckle protruding clamping portion 52; the sub-buckle base 51 is a plate-like or block-like structure; the sub-buckle protruding clamping portion 52 is a columnar structure with a pointed end, and its root is fixedly connected to the surface center of the sub-buckle base 51, and the columnar structure has a sub-buckle clamping flange 53, which is used to cooperate and clamp with the mother buckle clamping protrusion.

[0063] The mother buckle 4 and the child buckle 5 are made of plastic material with certain elasticity, which can meet the requirement that the child buckle protrusion clamping part 52 passes through the mother buckle and is stuck. Pulling the child buckle 5 with force can also make the child buckle 5 break free and come out, completing the disassembly.

[0064] As an improvement, the bottom surface of the female buckle base 41 has a recessed portion 46, which cooperates with the male buckle base 51 to make the bottom shapes of the female buckle and the male buckle more closely fit.

[0065] The installation structure of the side trim panel of the interior of the logistics vehicle provided in this embodiment also includes a compression sponge ring 7, which is sleeved on the root of the female buckle expansion clamping part 42.

[0066] When in use, in the first step, the sub-buckle 5 is half inserted into the female buckle 4, at which time the expanded clamping arm 44 has not expanded; then the female buckle and the sub-buckle are passed through the mounting hole of the interior side panel decorative panel as a whole and inserted into the inner panel mounting hole 6; then the sub-buckle 5 is pushed further forward to clamp the expanded clamping arm 44 with the inner panel mounting hole 6, at this time, the sub-buckle clamping flange 53 cooperates with the inner clamping protrusion 45 of the female buckle to clamp, completing the installation of the interior side panel decorative panel.
