[0013] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0014] This embodiment discloses a modular suitcase with a split structure, such as... Figures 1 to 11 As shown, a first storage box 3 and a second storage box 4 are included, each having a pull rod 1 and a moving wheel 2. The second storage box 4 is detachably bound to the first storage box 3 by a support assembly 5 and a strap 6. The support assembly 5 includes a tray 51 that protrudes horizontally from the first storage box 3 to support the second storage box 4. When the second storage box 4 is fixed to the side of the first storage box 3 by the strap 6, the lower end of the second storage box 4 is supported by the tray 51. The side walls of the second storage box 4 and the first storage box 3 are provided with channels 7 for the strap 6 to pass through.

[0015] In this embodiment, the support component 5 includes a tray 51 and a locking pin 52. The tray 51, hinged to the side wall of the first storage box 3, extends from a vertical position to a horizontal position relative to the side wall of the first storage box 3 and is stably supported by the locking pin 52. This embodiment is provided with a tray 51 having a telescopic structure, which facilitates the storage of the tray 51 and the storage and handling of this embodiment.

[0016] In this embodiment, the side wall of the first storage box 3 is provided with a mounting groove 31 for accommodating the support component 5. This embodiment uses the mounting groove 31 to ensure that the tray 51 and the support component 5 are strictly folded when stored, resulting in a simple appearance and reduced space occupation.

[0017] In this embodiment, the mounting groove 31 includes a first receiving groove 311 for accommodating the tray 51 and a second receiving groove 312 for accommodating the locking pin 52, wherein the first receiving groove 311 and the second receiving groove 312 are connected. In this embodiment, the first receiving groove 311 and the second receiving groove 312 are stably supported and positioned by the locking pin 52, which is hinged to the side wall of the first storage box 3. The structure is compact and easy to use.

[0018] In this embodiment, the locking pin 52 has a pin body, and the pin body is provided with limiting bosses 521 on both sides facing the first storage box 3 and the tray 51. In this embodiment, the bosses are frustum structures. When the tray 51 is in a vertical storage state, the pin body is vertically inserted into the first limiting track 313 opposite to the second receiving groove 312 through the bosses 521 on both sides. The pin body extends into the second limiting track 511 on both sides of the clearance notch in the middle of the tray 51 through the bosses 521. The tray 51 is inserted into the first limiting track 313 and the second limiting track 511 respectively through the bosses 521 on both sides of the pin body, positioning the tray 51 in a vertical position.

[0019] In this embodiment, the pin body is provided with a pull-out protrusion 522. When the support plate 51 is limited to the vertical position by the locking pin 52, the pull-out protrusion 522 protrudes from the support plate 51. This embodiment facilitates the insertion and removal of the locking pin 52 by providing the pull-out protrusion 522.

[0020] In this embodiment, the second storage box 4 is detachably bound to the first storage box 3 via the support component 5 and the strap 6. On the one hand, the second storage box 4 provides stable storage and positioning for items that need to be stored separately. The strap 6 supports and binds the second storage box to the first storage box 3, which has a pull rod 1 and moving wheels 2, via the tray 51, facilitating the movement of the combined suitcase. The second storage box 4 is stably supported by the first storage box 3, and the relative displacement between the two is small in the combined state. In this embodiment, by setting the first storage box 3 and the second storage box 4 as a connection structure with mutual support and fixation, it is convenient to store items separately while allowing the first storage box 3 and the second storage box 4 to move synchronously, and it is also convenient for storage.

[0021] To adapt to different usage scenarios, the second storage box can be designed as a long, narrow box. By utilizing its length, the volume of the second storage box can be increased, making it suitable for storing large and long items, such as bedding, musical instruments, or fishing gear.

[0022] In this embodiment, the locking pin 52 is inserted into the first limiting track 313 and the second limiting track 511 using its own rigid structure. The specific working method is as follows: When the tray 51 is in a vertical, retracted position, the locking pin 52 inserts its body into the clearance notch between the second receiving groove 312 and the tray 51. The protrusions 521 on both sides of the locking pin 52 are respectively positioned within the first limiting rail 313 and the second limiting rail 511, thus positioning the tray 51 within the first receiving groove 311. More specifically, the locking pin 52, through the cooperation of two pairs of protrusions 521 with the second limiting rail 511, ensures that the tray 51 is in a vertical, retracted position, effectively positioning the tray 51. When the tray 51 needs to be unfolded to support the second storage box 4, the locking pin 52 is pulled upwards, and the protrusions 521 on both sides of the locking pin 52 move along the first limiting rail 313 and the second limiting rail 511 until they reach the two pairs of protrusions within the first limiting rail 313. In step 521, the upper boss 521 disengages from the first limiting track 313. In this state, the locking pin 52 rotates relative to the side wall of the first storage box 3 via the boss 521, which is still within the first limiting track 313. As the tray 51 flips from a vertical position to a horizontal position, the locking pin 52 is in an inclined position. The lower end of the locking pin 52 is supported by the side wall of the first storage box 3, and the upper end of the locking pin 52 is supported by the tray 51, thus forming a stable triangular support structure. When the second storage box 4 is placed on the tray 51, the locking pin 52 is supported between the tray 51 and the side wall of the first storage box 3, effectively dispersing the downward pressure on the tray 51 to the side wall of the first storage box 3. This embodiment provides stable support. The first storage box 3 and the second storage box 4 are bound together with straps 6, effectively achieving relative fixation between the two, which facilitates the movement, use, and storage of this embodiment.

[0023] The above embodiments and figures are not intended to limit the product form and style of this embodiment. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this embodiment.
