[0025] The side shell 2 includes an inner shell 201, which is movably sleeved inside the main frame 1, and a polylactic acid jacket 203 is movably sleeved outside the main frame 1. Four reinforcing frames 202 are fixedly connected between the inner shell 201 and the polylactic acid jacket 203. The reinforcing frames 202 can support the inner shell 201, thereby enhancing the strength of the inner shell 201, and the polylactic acid jacket 203 can play a waterproof role.

[0026] The bottom plate 4 includes a reinforcing plate 401, which is movably sleeved inside the main frame 1. The top of the reinforcing plate 401 is fixedly connected to the upper plate 402, and the bottom of the reinforcing plate 401 is fixedly connected to the polylactic acid film 403. The reinforcing plate 401 can increase the pressure-bearing capacity of the bottom plate 4, thereby avoiding the bottom being exposed when loading goods. The polylactic acid film 403 fixedly connected to the bottom of the reinforcing plate 401 can play a role in water isolation, and the degradability of the polylactic acid film 403 can also reduce environmental pollution.

[0027] Furthermore, in the above technical solution, the reinforcing frame 202 is a cross-shaped groove plate, and the reinforcing frame 202 is in contact with the main frame 1. The reinforcing frame 202 is in contact with the main frame 1 to limit the inner shell 201, so that the inner shell 201 is more stable inside the main frame 1.

[0028] Furthermore, in the above technical solution, the reinforcing plate 401 is honeycomb-shaped, and the honeycomb-shaped reinforcing plate 401 can improve the bearing capacity and reduce the weight at the same time.
