[0039] To further enhance the stability of the column cover 4 after installation, in some embodiments, the column cover 4 is detachably connected to several frames 3, that is, the column cover 4 is connected to the frames 3, thereby increasing the stability of the column cover 4 after installation.
[0040] It should be noted that the connection method between the frame 3 and the column cover 4 is not limited in this embodiment of the utility model.
[0041] In some embodiments, structural adhesive can be provided between the column cover 4 and the several frames 3 to achieve a detachable connection between the column cover 4 and the several frames 3. That is to say, during installation, only structural adhesive needs to be applied between the column cover 4 and the several frames 3 to achieve adhesion. It is also easier to remove during disassembly. Moreover, this installation method is simpler and more efficient, which is conducive to further improving the disassembly and installation efficiency of the column cover 4.
[0042] In other embodiments, threaded holes are made in the frame 3, and bolts are used to achieve a detachable connection between the column cover 4 and several frames 3. That is, by adding bolts to fix the column cover 4 to the frame 3, the column cover 4 can be quickly disassembled, and the column cover 4 is more securely fixed, thus improving the stability of the column cover 4.
[0043] In other embodiments, a slot is provided on the frame 3, and a protruding block is provided at a corresponding position on the column cover 4. The column cover 4 and several frames 3 are detachably connected by the cooperation of the protruding block and the slot.

[0046] It should be noted that in this embodiment of the present invention, threaded holes can also be provided on the vehicle body 1 and through holes can be provided at the corresponding positions on the frame 3. The frame 3 can be fixed by bolts passing through the through holes and engaging with the threaded holes.
[0047] Please refer to Figure 1 To further enhance the stability of the column cover 4 after installation, in some embodiments, the vehicle body 1 is provided with a fixing member 6 and a connector 8. A gap is left between the fixing member 6 and the side wall 2. The column cover 4 is inserted into the gap between the fixing member 6 and the side wall 2 along the length direction of the vehicle body 1 to fix it to the vehicle body 1. The other side of the column cover 4 is fixed to the vehicle body 1 through the connector 8. That is to say, by connecting the two sides of the column cover 4 to the fixing frame and the connector 8 respectively, the column cover 4 is fixed to the vehicle body 1.
[0048] It should be noted that the specific structure of the connector 8 is not limited in this embodiment of the utility model. In some embodiments, the connector 8 may have a groove structure, and one side of the column cover 4 is inserted into the groove to achieve the insertion. Alternatively, the connector 8 may have a fixing protrusion on its contact surface with the column cover 4, and a corresponding groove on the contact surface between the column cover 4 and the connector 8, so that the column cover 4 and the connector 8 are attached together and the fixing protrusion is placed inside the groove to achieve the insertion function.
[0049] Furthermore, the specific structure of the fastener 6 is not limited in this embodiment. In some embodiments, the fastener 6 can adopt a block-shaped, plate-shaped, or other structure, as long as a gap is left between the fastener 6 and the side wall 2 for the column cover 4 to be inserted.
[0050] In some embodiments, the fastener 6 is L-shaped and is fixed to the vehicle body 1 by bolts. The contact surface between the fastener 6 and the pillar cover 4 is provided with anti-slip texture. Specifically, one side of the L-shaped connector 8 is fixed to the vehicle body 1, and the other side faces the side wall 2, so that a gap is formed between the fastener 6 and the side wall 2. At the same time, in order to increase the fixing effect on the pillar cover 4, anti-slip texture is provided on the contact surface between the fastener 6 and the pillar cover 4 to increase friction and thus enhance the fixing effect on the pillar cover 4.
[0051] In some embodiments, a felt 7 is provided between the fixing member 6 and the column cover 4. The felt 7 can not only enhance the friction of the contact surface between the fixing member 6 and the column cover 4, but also improve the fit effect when the fixing member 6 and the column cover 4 are inserted. By enhancing the interference fit between the fixing member 6 and the column cover 4, the effect of improving the fixing firmness is achieved.
[0052] It should be noted that the description of the felt 7 in the embodiments of this utility model is not a fixed limitation. In some embodiments, it can be replaced by other materials, such as rubber, silicone, metal, etc.
[0053] In some embodiments, the side of the column cover 4 away from the frame 3 is provided with a chamfer. The chamfer can increase the aesthetics of the column cover 4 during use, and at the same time improve the safety of the column cover 4 during use.
[0054] In addition to the above-mentioned rail vehicle door pillar cover installation structure, this utility model also provides a rail vehicle including the above-mentioned rail vehicle door pillar cover installation structure, wherein the pillar cover at the door is easy to disassemble.
[0055] Several frames 3 are installed on the vehicle body 1 and arranged along the height direction of the vehicle body 1.

The cross-section of the pillar cover 4 is C-shaped, and a cavity is formed between the pillar cover 4 and the vehicle body 1. Several frames 3 are placed inside the cavity. The C-shaped pillar cover 4 itself can enhance a certain compressive strength. At the same time, the frames 3 support the pillar cover 4, which helps to improve the compressive strength of the pillar cover 4 during use, thereby avoiding damage to the pillar cover 4 during use. In addition, the pillar cover 4 and the frames 3 are detachably connected. When maintenance is required, only the pillar cover 4 needs to be removed, which greatly improves the efficiency of disassembly and installation of the pillar cover 4.
