[0028] like Figure 1-3 As shown, a combined carriage side wall includes: a frame 1, an upper wall 2, a lower wall 3, a fastening beam 5, a first reinforcing rib 6, and a second reinforcing rib 7.

[0029] The frame 1 consists of several longitudinal beams 11 and transverse beams 12 spliced ​​together; the frame 1 is made of stainless steel or aluminum alloy.

[0030] The upper wall 2 is integrally molded from epoxy resin profile, and its inner side is fixedly connected to the upper outer side of the frame 1. The upper wall 2 has openings 21 for installing windows, and longitudinal beams 11 and transverse beams 12 are arranged around the openings 21.

[0031] The lower wall 3 is integrally molded from epoxy resin profiles, and its inner surface is fixedly connected to the lower outer side of the frame 1. To improve the stability and strength of the upper wall 2 and the lower wall 3, both the upper wall 2 and the lower wall 3 have several reinforcing beams 4 along the length of the carriage on their inner surfaces. The reinforcing beams 4 are hollow rectangular beams. The reinforcing beams 4 are profiles manufactured simultaneously with the integral molding of the walls.

[0032] like Figure 6 As shown, in order to achieve a tight connection between the upper wall 2 and the lower wall 3, the bottom surface of the upper wall 2 has a groove 22 along the length of the carriage, and the top surface of the lower wall 3 has a slider 31 along the length of the carriage. The slider 31 is slidably connected to the groove 22. To ensure that the tight connection between the slider 31 and the groove 22 does not come off and is watertight, the inner sidewall of the groove 22 has a groove, and the sidewall of the slider 31 has a protrusion 32 embedded in the groove.

[0033] The fastening beam 5 is arranged longitudinally and is used to fix and connect the upper wall 2 and the lower wall 3. The fastening beam 5 is located at both ends along the length of the carriage on the inner side of the upper wall 2 and the lower wall 3. The fastening beam 5 is used to strengthen the connection strength of the wall edges and ensure the stability of the wall. The fastening beam 5 is made of stainless steel or aluminum alloy.

[0036] To ensure that the frame 1, fastening beam 5, and reinforcing ribs can be securely connected to the wall, connector 9 is also included, such as... Figure 5 As shown, connector 9 is made of stainless steel and has a locking block 91 that covers the reinforcing beam. The locking block 91 is fixedly connected to the reinforcing beam by fasteners. One end of connector 9 is fixedly connected to the longitudinal beam, the fastening beam, the first reinforcing rib, or the second reinforcing rib. Of course, as... Figure 4 As shown, in order to further simplify the production of the first reinforcing rib 6 and the second reinforcing rib 7, the connector 9 is made into one piece with the reinforcing rib, that is, the first reinforcing rib and the second reinforcing rib have a connector structure, and the connector on the first reinforcing rib and the second reinforcing rib is also a nylon injection molded part, and the connector and the reinforcing rib are integrally injection molded.

[0037] To further improve the thickness and protective effect of the lower wall, longitudinal beams 8 are fixedly connected to the longitudinal beams, fastening beams and second reinforcing ribs of the lower wall 3.
