Detailed Implementation
[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The embodiments described below are merely examples, and other obvious variations will arise for those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.
[0024] like Figures 1 to 7The diagram shows a mother-daughter suitcase, comprising a daughter suitcase 1 and a mother suitcase 2. The upper part of the mother suitcase 2 is provided with an L-shaped section 3. The daughter suitcase 1 can be detachably fitted onto the L-shaped section 3 to form a complete suitcase. The daughter suitcase 1 includes two relatively openable parts, namely a first body 4 and a second body 5, which are connected by a zipper. The zipper includes a first chain 6 on the first body 4 and a second chain 7 on the second body 5. The width of the first body 4 is smaller than the width of the second body 5. The vertical part 8 of the L-shaped section 3 is set as a recess. When the daughter suitcase 1 is fitted with the L-shaped section 3, the first body 4 is fitted with the recess, and the first chain 6 is fitted and abutted against the opening of the recess. At the same time, the fact that the width of the first body 4 is smaller than the width of the second body 5 makes the depth of the recess shallower, that is, under the premise of the shallow depth of the recess, it is possible to partially or mostly fit the opening of the first chain 6 with the recess.
[0025] To ensure a better fit, the recess is a basin-shaped recess that matches the shape of the first housing 4.
[0026] The mother box 2, the first box 4, and the second box 5 are all PVC boxes (polyvinyl chloride boxes), which have a certain elasticity and stiffness and can maintain a certain shape. The first chain part 6 includes half of the zipper 25 21 and the first base fabric 23. Similarly, the second chain part 7 includes the other half of the zipper 25 22 and the second base fabric 24. The first base fabric 23 and the second base fabric 24 can be made of fabric material. When the first chain part 6 is sleeved and fitted with the opening of the recess, the thickness of the fabric material of the first chain part 6 can form a certain fit, thereby preventing large gaps and avoiding looseness, which helps to reduce noise.
[0027] And, as Figure 2 , 3 As shown in Figure 4, the horizontal portion 9 of the L-shaped part 3 is provided with a recess 10. The number of recesses 10 is the same as the number of legs 11 of the sub-box 1. When the sub-box 1 is engaged with the L-shaped part 3, the legs 11 and the recesses 10 are inserted into each other to fix the bottom of the sub-box 1.
[0028] And, as Figure 1 , 4 As shown in Figure 5, the first chain section 6 is provided with a first chain buckle 12, and the second chain section 7 is provided with a second chain buckle 13. A lock hole 14 is provided on the top surface of the mother box 2 near the L-shaped section 3. The first latch 20 of the first chain buckle 12 and the second latch 21 of the second chain buckle 13 are inserted into the lock hole 14 to secure the top of the daughter box 1. In this example, the top surface of the mother box 2 is provided with a combination lock, and the lock hole 14 is provided by the combination lock. When the combination lock is unlocked, the first latch 20 of the first chain buckle 12 and the second latch 21 of the second chain buckle 13 can disengage from the lock hole 14.
[0029] In some embodiments, such asFigure 2 , 3 As shown in Figure 4, the support leg 11 is a tapered support leg with a smaller bottom and a larger top, and the recess 10 is a tapered recess. The tapered support leg and the tapered recess can be detachably plugged in. This makes the plugging in easier.
[0030] Furthermore, such as Figure 3 , 4 As shown, the two legs 11 of the first housing 4 are arranged linearly with a spacing of L1, and the two legs 11 of the second housing 5 are also arranged linearly with a spacing of L2, where L1 is less than L2. Furthermore, the two legs 11 of the first housing 4 and the two legs 11 of the second housing 5 are arranged at the four corners of an isosceles trapezoid. This foolproof design facilitates user operation and ensures a proper fit between the first housing 4 and the recess, thus achieving the design objective.
[0031] In some embodiments, such as Figure 6 , 7 As shown, the L-shaped portion 3 of the mother box 2 has a bottom fabric 15 covering the entire bottom surface of the box, and a mesh fabric 16 covers the upper side of the bottom fabric 15. The portion of the mesh fabric 16 corresponding to the back side 17 of the vertical portion 8 is fitted to the bottom fabric 15, while the portion of the mesh fabric 16 corresponding to the recess 18 of the box extends across the recess 18 to act as a cover for the recess 18. In this way, since the mother box 2 is also composed of two boxes that open and close relative to each other, the mesh fabric 16 is used to isolate the interior of the box on the L-shaped portion 3 side from the interior of the box on the opposite side, thereby creating a better storage space inside the box on the L-shaped portion 3 side.
[0032] like Figure 6 As shown, the bottom fabric 15 is a single piece of fabric laid flat along the back 17 and the surface of the recess 18 to protect the internal luggage.
[0033] The mesh fabric 16 includes an openable portion 19 that covers the back surface 17 and the cavity 18. Thus, as... Figure 6 As shown, when the openable part 19 is opened, the back 17 is also exposed, so that some luggage, such as thin luggage like documents and passports, can be conveniently placed on the back 17.
[0034] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
