[0050] like Figures 1 to 4 As shown, this utility model provides a trim panel installation structure, including a first interior trim panel 1, a second interior trim panel 2, and a first buffer member 3. The first interior trim panel 1 is Z-shaped and includes a first connecting segment A11, a first connecting segment B12, and a first connecting segment C13 connected in sequence. The first connecting segment A11 is used to fix to a steel structure 4 in a first direction M. The first connecting segment C13 is located away from the steel structure 4 relative to the first connecting segment A11. The second interior trim panel 2 is L-shaped and includes a second connecting segment A21 and a second connecting segment B22 connected in sequence. The second connecting segment A21 and the first connecting segment A11 are spaced apart in the first direction M. The second connecting segment A21 and the first connecting segment C13 are on the same plane or curved surface. The free end of the second connecting segment B22 faces the first connecting segment A11 and is spaced apart from the first connecting segment A11. The first buffer member 3 is located in the first direction M and is sandwiched between the first connecting segment A11 and the second connecting segment A21, serving to connect the first connecting segment A11 and the second connecting segment A21.
[0051] For example, the first connecting segment A11 is parallel to the first connecting segment C13 and is perpendicular to the first connecting segment B12. The second connecting segment A21 is perpendicular to the second connecting segment B22 and parallel to the first connecting segment A11. The projection of the second connecting segment A21 onto the first connecting segment A11 in the first direction M is at least partially overlapping with the first connecting segment A11. The overlapping portion is sandwiched with a first buffer 3. The second connecting segment A21 and the first connecting segment C13 form a relatively flat surface. The second connecting segment B22 is parallel to the first connecting segment B12. The free end of the second connecting segment B22 faces the first connecting segment A11. That is, in the second direction N, the projection of the second connecting segment B22 onto the first connecting segment B12 is overlapping, and the free end of the second connecting segment B22 is spaced apart from the first connecting segment A11. The first connecting section A11 is used to connect with the steel structure 4. The side of the first connecting section A11 away from the first connecting section B12 is covered by the second interior panel 2, reducing the exposure of the steel structure 4. The alignment of the second connecting section A21 with the first connecting section C13 makes the side of the interior panel mounting structure facing away from the steel structure 4 relatively smooth and flat, improving its aesthetics. The first buffer 3 between the first interior panel 1 and the second interior panel 2 can undergo elastic deformation. When subjected to external force, there is a space for movement between the first interior panel 1 and the second interior panel 2, which can squeeze the first buffer 3, absorb part of the force, and achieve the effect of shock absorption, avoiding abnormal noise caused by relative friction between the first interior panel 1 and the second interior panel 2 due to compression.
[0052] For example, the buffer 3 is connected to the first connecting segment A11 and the second connecting segment A21 by adhesive bonding.
[0053] Optionally, the trim panel mounting structure also includes an adjusting pad 5, which is sandwiched between the first connecting section A11 and the steel structure 4. This arrangement allows the adjusting pad 5 to fill the gap between the first connecting section A11 and the steel structure 4, ensuring reliable installation.
[0054] Optionally, the decorative panel mounting structure also includes a first mounting nail 61. The first mounting nail 61 passes through the second connecting section A21, the first buffer 3 and the first connecting section A11 in sequence along the first direction M and is then connected to the steel structure 4. A countersunk hole is provided on the side of the second connecting section A21 opposite to the first connecting section A11, and the nut of the first mounting nail 61 is located in the countersunk hole.
[0055] For example, the first mounting pin 61 is a screw, including a nut and a stud. The stud is inserted into the second connecting section A21, the first buffer 3 and the first connecting section A11 and is threadedly connected to the steel structure 4. The nut is inserted into the countersunk hole of the second connecting section A21. In this way, the nut of the first mounting pin 61 is exposed outside the second connecting section A21 but does not protrude from the second connecting section A21, which facilitates disassembly and maintains aesthetics.
[0056] Optionally, the first buffer 3 includes a first buckle A31 and a first buckle B32. The first buckle A31 is fixed to the side of the second connecting segment A21 facing the first connecting segment A11, and the first buckle B32 is fixed to the side of the first connecting segment A11 facing the second connecting segment A21. The first buckle A31 and the first buckle B32 are connected.
[0057] For example, the first buffer 3 is a mushroom-shaped hook and loop fastener.
[0058] Optionally, the trim panel mounting structure also includes a second mounting nail 62. The second mounting nail 62 passes through the first connecting section A11 along the first direction M and is fixed to the steel structure 4. The first connecting section A11 has a countersunk hole on the side facing away from the steel structure 4. The nut of the second mounting nail 62 is inserted into the countersunk hole in the first direction M. The second connecting section A21 covers the nut.
[0059] For example, the second mounting pin 62 is a screw, including a nut and a stud. The stud passes through the first connecting section A11 and is threaded to the steel structure 4. During assembly, the first interior panel 1 is first fixed to the steel structure 4 by the second mounting pin 62, and then the first buffer 3 and the second interior panel 2 are installed on the first interior panel 1 in sequence. The second connecting section A21 of the second interior panel 2 covers the nut of the second mounting pin 62 and hides the second mounting pin 62 to ensure aesthetics.
[0060] Optionally, the first buckle B32 covers the countersunk hole.
[0061] Optionally, the second connecting segment A21 is connected to the steel structure 4 via the second buffer 7. The second buffer 7 includes a second buckle A71 and a second buckle B72. The second buckle A71 is installed on the side of the second connecting segment A21 facing the steel structure 4, and the second buckle B72 is fixed to the steel structure 4 via a third mounting nail 63. The second buckle A71 and the second buckle B72 are connected.
[0062] For example, the second buffer 7 is a mushroom-shaped hook and loop fastener.
[0063] During assembly, the second buckle B72 is first installed on the steel structure 4 via the third mounting nail 63, and the second buckle A71 is installed on the second connecting section A21. The second connecting section A21 and the steel structure 4 are fixed by the connection between the second buckle A71 and the second buckle B72. The second interior panel 2 then covers the third mounting nail 63, forming a hidden installation structure that ensures the aesthetics of the structure.

Any two of the top wall 8, the rear wall 9 and the side wall 10 are connected by the above-mentioned trim panel mounting structure.
[0065] This design improves the cab's shock absorption performance, reduces abnormal noises, and enhances the overall aesthetics.
[0066] Optionally, the top wall 8 includes a front top plate 81, a middle top plate 82, and a rear top plate 83 fixed sequentially from front to back along the front-rear direction X. A rear wall 9 is fixed to the side of the rear top plate 83 opposite to the middle top plate 82. The rear wall 9 includes a rear wall door panel 91 and two rear wall side panels 92. The rear wall side panels 92 are respectively fixed to the opposite sides of the rear wall door panel 91 in the left-right direction Y. The side wall 10 includes a side wall top plate 101, a side wall window panel 102, and a side wall door panel 103 fixed sequentially from front to back along the front-rear direction X.
[0067] For example, during assembly, the rear wall door panel 91 and the rear wall side panel 92 are first assembled to form the rear wall; then the side wall top panel 101, the side wall window panel 102 and the side wall door panel 103 are assembled to form the side wall panel; then the front top panel 81, the middle top panel 82 and the rear top panel 83 are assembled to form the top wall 8.
