[0040] Specific structure such as Figures 1 to 9 shown.

[0041] The present embodiment provides a multifunctional suitcase, comprising: a front case shell 1, a rear case shell 2, a telescopic pull rod assembly 3 and a flip backrest 8; the front case shell 1 and the rear case shell 2 are arranged opposite to each other and are connected to form a case body by a first connecting structure 5; a front cover 21 is arranged on the side of the front case shell 1 facing away from the rear case shell 2, and the telescopic pull rod assembly 3 is arranged on the rear case shell 2; one end of the flip backrest 8 is hinged to the opposite sides of the case body, and the flip backrest 8 has an open state and a buckled state relative to the case body.

[0042] In this embodiment, the front box shell 1 and the rear box shell 2 are connected by a first connecting structure 5 to form a box body, and a flip backrest 8 is hinged on opposite sides of the box body. When the child needs to rest, it is only necessary to rotate the flip backrest 8 to put it in an open state, and the child can be held and placed on the top of the box body with his back against the flip backrest 8, which is convenient for the child to rest. When not in use, it is only necessary to rotate the flip backrest 8 to make it buckled on the side of the box body in a buckled state. It is easy to use and has a beautiful structure. Since a front cover 21 is provided on the side of the front box shell 1 away from the rear box shell 2, there is no need to hold the child when the child sits on the top surface of the box. Articles can be placed in the box body or taken out of the box body by opening the front cover 21, which is convenient to use.

[0043] In the optional technical solution of this embodiment, the first connecting structure 5 includes a middle frame. In this case, the middle frame is an integrated structure, and the middle frame is located between the front box shell 1 and the rear box shell 2, and the front box shell 1 and the rear box shell 2 are fixed to the middle frame by rivets. Preferably, the middle frame is an aluminum frame. In this case, the front box shell 1 and the rear box shell 2 are fixed as a whole by the middle frame and cannot be opened. The box can only be opened through the front cover 21.

[0044] In the optional technical solution of this embodiment, the middle frame includes a first frame body and a second frame body that can be relatively opened and closed; the first frame body is connected to the front box shell 1, and the second frame body is connected to the rear box shell 2. In this case, the middle frame is a split type, that is, it includes a first frame body connected to the front box shell 1 and a second frame body connected to the rear box shell 2. One side of the first frame body and the second frame body are hinged by a hinge, and the other side is connected by a lock. When the lock is opened, the first frame body and the second frame body can be relatively opened, so that the box body is opened. With this arrangement, when the flip backrest 8 is in the open state, the box body can be opened through the front cover 21. When the flip backrest 8 is in the buckled state, the box body can be opened through the front cover 21 and the first frame body and the second frame can also be opened, thereby improving applicability.

[0045] In the optional technical solution of this embodiment, the first connecting structure 5 includes a zipper. In this arrangement, when the flip backrest 8 is in the open state, the box can be opened through the front cover 21, and when the flip backrest 8 is in the buckled state, the box can be opened through the front cover 21 and by unzipping the zipper, which improves applicability.

[0046] In the optional technical solution of this embodiment, a sink is provided on the outer edge of the top of the box body, and when the flip backrest 8 is in the open state, the flip backrest 8 is located at the top of the box body, and the hinged end of the flip backrest 8 abuts against the sink.

[0047] Specifically, taking the flip backrest 8 in the open state as an example, the bottom end of the flip backrest 8 is hinged to the two sides of the box body, wherein two connecting plates may be arranged at the bottom end of the flip backrest 8, and the connecting plates are hinged to the hinge shafts on both sides of the box body, wherein the sinker includes a first sinker 9 located on the front box shell 1 and a second sinker 10 located on the rear box shell 2, the bottom end of the flip backrest 8 is abutted against the first sinker 9, and the flip backrest 8 is located on the top side of the box body, and the top of the box body and the flip backrest 8 form a seat for convenient sitting and resting.

[0048] In the optional technical solution of this embodiment, a sinking storage portion 11 is provided on the side of the rear box shell 2 away from the front box shell 1, and when the flip backrest 8 is in the buckled state, the flip backrest 8 is located in the sinking storage portion 11. When not in use, the flip backrest 8 can be rotated to be located in the sinking storage portion 11, so that the surface of the side of the front box shell 1 away from the front box shell 1 is flat, the structure is beautiful, and it is convenient to open and buckle, and the flip backrest 8 is prevented from being damaged.

[0049] In an optional technical solution of the present embodiment, side enclosures 12 are provided on the left and right sides of the flip backrest 8, and one end of the side enclosure 12 is hinged to the box body.

[0050] Specifically, the lower ends of the side enclosures 12 on the left and right sides of the flip backrest 8 are hinged to the hinge shaft, wherein the hinge shaft can be located on the front box shell 1 or on the rear box shell 2. The flip backrest 8 and the side enclosures 12 on both sides are U-shaped as a whole. When a child sits on the top of the box body, the flip backrest 8 and the side enclosures 12 together prevent the child from falling, thereby improving safety.

[0051] In the optional technical solution of this embodiment, a U-shaped front enclosure 13 is hinged on the side enclosure 12. The two ends of the U-shaped front enclosure 13 are respectively hinged on the two side enclosures 12. When in the buckled state, the U-shaped front enclosure 13 is located between the two side enclosures 12 by rotation, and the U-shaped bottom of the U-shaped front enclosure 13 is located in the sinking storage portion 11 together with the flip backrest 8. When in the open state, the U-shaped front enclosure 13 can be located outside the two side enclosures 12 by rotation, and forms a ring structure with the flip backrest 8 and the side enclosure 12. When a child sits on the top of the box, the flip backrest 8, the side enclosure 12 and the U-shaped front enclosure 13 prevent the child from falling in the circumferential direction, thereby improving safety.

[0052] In the optional technical solution of this embodiment, a scale line 22 is provided on the telescopic rod of the telescopic pull rod assembly 3 along the telescopic direction.
