[0002] The existing ride-on trolley cases are L-shaped in overall shape, which makes it unsafe for children to sit on them without any support on the backrest. In addition, because the case is L-shaped, the area where the seat can be sat on is sunken, resulting in a waste of capacity.

[0003] Due to this restriction, existing ride-on trolley cases are equipped with a safety belt for safety reasons. However, the safety belt is neither practical nor safe. According to relevant regulations, the size measurement method for carry-on cases and checked luggage is to calculate the size according to the sum of three sides. Some ride-on trolley cases are now L-shaped, which reduces the capacity of carry-on luggage.

[0004] Existing trolley cases with sit-on features lack the capacity for sitting, so this invention adds a small bag that can hold some items, increasing the capacity utilization of the trolley case. Also, considering the safety of children sitting on it, the small bag body is set to a backrest mode, which can be folded 90 degrees and used as a backrest. The small bag body is detachable, and after being detached, the box body becomes L-shaped. The small bag body can be separated and used as a shoulder bag with a shoulder strap to hold some items that need to be carried on the person. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-7 , a trolley case with a detachable backrest, includes a trolley case body 10, characterized in that M-shaped grooves 11 are provided on the front and rear side walls of the trolley case body 10, and a foot support 12 extending outward is provided below the M-shaped groove 11; a hinge mechanism is installed on the right side wall of the trolley case body 10, and the hinge mechanism is used to connect the small compartment bag body 30 and the trolley case body 10; a male buckle 31 is fixedly installed on the upper side wall of the small compartment bag body 30, and a female buckle 32 is installed above the trolley case body 10; a chamfer 33 is provided below the small compartment bag body 30; a draw buckle 34 is provided on the side wall of the small compartment bag body 30, and the draw buckle 34 is used in conjunction with a shoulder strap 40, one end of the shoulder strap 40 is set as a belt snap 41, and the other end of the shoulder strap 40 is set as a female buckle joint 42, and a hand ring 50 is also provided on the side wall of the small compartment bag body.

[0029] As an optimization scheme of this embodiment, the hinge mechanism includes a lower page plate 21, a lower page plate 22, a fixing pin 23, a latch 24, a spring 25, and an upper page plate 26. The right side wall of the trolley box body 10 is installed with the lower page plate 21 and the lower page plate 22 by rivets. The lower page plate 22 is connected to the upper page plate 26 by a string of fixing pins 23. The lower page plate 121 is connected to the upper page plate 26 by a string of latches 24. The side wall of the upper page plate 26 is installed with the small box bag body 30 by rivets.

[0030] As an optimization solution of this embodiment, the spring 25 is provided between the latch 24 and the lower page plate 21 to provide elastic force to the latch 24. The provision of the spring 25 can reduce the generation of noise to a certain extent.

[0031] It should be noted that when the operator moves the handle of the latch 24 to the horizontal position, the elastic force of the spring 25 pushes the latch 24 to the far right, thereby facilitating the operator to separate the upper page plate 26 and the lower page plate 21; and when installing the upper page plate 26 again, it is only necessary to pass the right side of the upper page plate 26 through the fixing pin, and then fit the left side of the upper page plate 26 with the upper page plate 21, and finally push the latch 24 to the left to squeeze the spring 25, and press the latch 24 down into the lower page plate 21.

[0032] As an optimization of this embodiment, the thickness of the lower panel 1 21 and the lower panel 2 22 is greater than that of the upper panel 26 , and is used to limit the opening range of the small compartment body 30 to a maximum of 90 degrees, allowing the small compartment body 30 to be used as a backrest. When the small compartment body 30 is opened to its maximum 90 degrees, a child can sit astride the suitcase body 10 , with their feet resting on the footrests 12 on the front and rear walls, while using the small compartment body 30 as a backrest, giving the child a sense of security.

[0033] As an optimization solution of this embodiment, the female buckle joint 42 can be connected to the male buckle belt 31. Thus, the shoulder strap 40 is installed on the small compartment bag body 30, and the supporting combination is used to form a shoulder bag.

[0034] As an optimization solution of this embodiment, the shoulder strap 40 can be stored inside the small compartment bag body 30 when not in use, which is convenient for storage and carrying.

[0035] The overall workflow of this utility model is as follows:

[0036] First, when the male buckle 31 and the female buckle 32 are separated and the small compartment body 30 is opened, that is, when the small compartment body 30 is opened to 90 degrees, a child can sit astride the suitcase body 10, with the child's feet respectively stepping on the foot supports 12 on the front and rear walls, and at the same time, the child can use the small compartment body 30 as a backrest, which can give the child a sense of security;

[0037] Secondly, when the male buckle 31 and the female buckle 32 are separated, when the handle of the latch 24 is moved to the horizontal position, the elastic force of the spring 25 pushes the latch 24 to the far right. At this time, the upper page plate 26 and the small compartment bag body 30 are loosened, and the operator pulls out the small compartment bag body 30 with force in the upward direction, and the upper page plate 26 is separated from the lower page plate 1 21 and the lower page plate 2 22; the operator takes out the small compartment bag.

[0038] Then, when the small box bag body 30 is taken out, the carrying ring 50 of the small box bag body 30 is put on the pull rod of the trolley case body, so that the child can use the footrest 12 as a footrest when sitting on the trolley case body 10; when the carrying ring is put on the pull rod of the trolley case body, the small box bag body 30 can be easily placed;

[0039] Finally, after taking out the small box bag body 30, the buckle 34 set on the side wall of the small box bag body 30 can be used together with the shoulder strap 40. The belt snap buckle 41 at one end of the shoulder strap 40 is passed through the buckle 34, and then pulled back and the snap buckle is installed in place. Then, the female buckle joint 42 at the other end of the shoulder strap 40 is connected to the male buckle belt 31, so as to achieve the purpose of removing the small box bag body 30 and using it as a shoulder bag.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
