[0033] Specifically, the bottom of the bottom shell 2 is provided with a reserved groove 23, and the expansion component 3 is movably installed in the reserved groove 23. This design allows the expansion component 3 to be pulled out when needed to expand the bottom space of the bag. Fixing blocks 33 are fixedly installed at the four corners of the inner side of the bottom shell 2. The bottom of the fixing blocks 33 is provided with a plug-in groove. This design provides a stable support point for the expansion component 3.

[0034] The expansion assembly 3 includes a base plate 31, with plug-in blocks 311 fixedly installed at the four corners of the upper surface of the base plate 31. The top of the plug-in block 311 is movably inserted into the plug-in groove at the bottom of the fixing block 33. This design ensures that the expansion assembly 3 can be stably fixed to the bottom shell 2 when expanding. The base plate 31 is covered with a telescopic cover 32. When expanding, the telescopic cover 32 unfolds and covers the bottom of the outer wall of the bottom shell 2. This not only protects the bottom shell 2 but also enhances the pressure resistance of the expanded part.

[0035] The fixed block 33 is provided with an opening and fixedly installed with a positioning assembly 331. The positioning assembly 331 includes a plug-in rod 3311, one end of the plug-in rod 3311 penetrates through the opening on the fixed block 33 and extends into a positioning hole 3111 on the plug-in block 311, and a connecting spring 3312 is sleeved on the plug-in rod 3311. Through the action of the spring, the stability of the entire expansion structure is enhanced, and stability can be maintained even under heavy pressure or jolt conditions.

[0036] Through these designs, the bag can provide better support and positioning after expansion, thereby improving the compression resistance of the expansion part and reducing the risk of shrinkage and damage to the articles due to external force. This design is practical and innovative, providing users with a more reliable and convenient bag experience.

[0039] In order to make the expansion assembly more stable when pulled out, as shown in the embodiment, the cross-sectional size of the reserved slot 23 matches the cross-sectional size of the bottom plate 31. Figures 1 to 5 The cross-sectional size of the reserved slot 23 matches the cross-sectional size of the bottom plate 31, ensuring that the expansion assembly 3 can smoothly slide and be fixed in the reserved slot 23, providing precise cooperation and stable expansion structure.

[0040] Further, the fixed block 33 is provided with an opening and fixedly installed with a positioning assembly 331, and the top of the fixed block 33 is flush with the upper end surface of the bottom shell 2. The top of the fixed block 33 is flush with the upper end surface of the bottom shell 2, maintaining the flatness of the bottom of the bag, making it easy to close the bag.

[0041] The positioning assembly 331 fixedly installed on the fixed block 33 enhances the stability of the expansion part, preventing displacement or damage under heavy pressure.

[0042] Further, the side of the telescopic cover 32 away from the bottom plate 31 is wrapped around the bottom of the outer wall of the bottom shell 2, and support foot pads are fixedly installed at the four corners of the lower surface of the bottom plate 31 inside the telescopic cover 32. In the design, the side of the telescopic cover 32 away from the bottom plate 31 is wrapped around the bottom of the outer wall of the bottom shell 2, providing additional protection against wear and damage to the bottom shell 2 during expansion.

[0043] The support foot pads fixedly installed at the four corners of the lower surface of the bottom plate 31 inside the telescopic cover 32 increase the support points of the luggage and the ground, thereby improving the stability when the luggage is placed.

[0044] In order to position the expansion assembly after being extracted or stored, as shown in Figs. 4 and 5, two positioning holes 3111 are formed on the plug-in block 311 in the embodiment, and the two positioning holes 3111 are longitudinally distributed along the outer wall of the plug-in block 311. The diameters of the two positioning holes 3111 are matched with the size of the opening on the fixing block 33. Figure 5 Figure 6 The two positioning holes 3111 formed on the plug-in block 311 in the design are matched with the size of the opening on the fixing block 33, thereby ensuring the accurate positioning and stable connection between the plug-in block 311 and the fixing block 33.

[0045] The longitudinal distribution of the two positioning holes 3111 along the outer wall of the plug-in block 311 enables the plug-in block 311 to be flexibly inserted and pulled out, thereby facilitating the user operation.

[0046] Further, the positioning assembly 331 includes a plug-in rod 3311, one end of which penetrates through the opening on the fixing block 33 and extends into the positioning hole 3111.
