DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figs. 1-4 In the embodiments of the utility model, a luggage case with an expansion wheel structure comprises a box 1, the bottom of the box 1 is provided with a walking wheel 3, the upper end of the box 1 is reversibly connected with an enclosure 4, the enclosure 4 can be reversibly turned into a first mode and a second mode relative to the box 1; when the enclosure 4 is turned into the first mode, a seat space for a child to sit is formed between the enclosure 4 and the top of the box 1, when the enclosure 4 is turned into the second mode, the enclosure 4 is folded on the outer wall of the box 1; the enclosure 4 is in the shape of a sheet plate structure, and the enclosure 4 is reversibly connected with the box 1 through a shaft rod.

[0023] The bottom of the box 1 is also provided with at least one expansion wheel assembly 5, the expansion wheel assembly 5 is reversibly connected with the box 1, and is used for expanding the supporting area of the bottom of the box 1; the expansion wheel assembly 5 comprises at least one first universal wheel 501, the connecting end of the first universal wheel 501 is fixedly connected with a first connecting rod 502, and the end, away from the first universal wheel 501, of the first connecting rod 502 is hingedly connected in a first groove 11 at the bottom end of the box 1; the first connecting rod 502 is in an L-shaped structure, when the first connecting rod 502 is reversibly turned to the maximum angle, the lowest point of the first universal wheel 501 is at the same horizontal position height as the lowest point of the walking wheel 3.

[0024] In the embodiments, the expansion wheel assembly 5 and the enclosure 4 are arranged, which can ensure that the luggage case is not easily turned over when a child sits on it, and can ensure that the luggage meets the boarding requirements, so that a family with a child can not be anxious about boarding.

[0025] Specifically, the first recess 11 in the scheme is internally provided with a shaft for hingedly rotating one end of the first connecting rod 502. When it is necessary to improve the stability of the box 1 in the vertical state, the first connecting rod 502 is rotated outward to the maximum angle with the shaft as the axis, and the end of the first connecting rod 502 connected with the shaft is parallel to the bottom end surface of the box 1. Then, the first universal wheel 501 is transferred to the outside of the bottom of the box 1 under the action of the rotation of the first connecting rod 502. At this time, the first universal wheel 501 not only increases the supporting area of the bottom end of the box 1, but also increases a supporting point, thereby greatly improving the stability of the vertical placement of the box 1.

[0026] The enclosure 4 in the scheme is made of existing hard plastic plate material, which is turned into the first mode state. Children can be held and sat in the seat space formed between the enclosure 4 and the box 1. In the first mode, the bottom end of the enclosure 4 is limited by the abutment of the outer wall of the box 1, so that the enclosure 4 will not rotate when the child leans on it, thereby ensuring the safety of the child's seat.

[0027] In another embodiment, a luggage case with an expanding wheel structure includes a box 1, a walking wheel 3 mounted at the bottom of the box 1, and an enclosure 4 reversibly connected to the upper end of the box 1. The enclosure 4 can be reversibly turned into a first mode and a second mode relative to the box 1. When the enclosure 4 is turned into the first mode, a seat space for a child to lean on is formed between the enclosure 4 and the top of the box 1. When the enclosure 4 is turned into the second mode, the enclosure 4 is folded on the outer wall of the box 1. The enclosure 4 has a piece-shaped plate structure in the shape of a Chinese character and is reversibly connected to the box 1 through a shaft.

[0028] The bottom of the box 1 is also provided with an expanding wheel assembly 5, which is reversibly connected to the box 1 to expand the supporting area of the bottom of the box 1. The expanding wheel assembly 5 includes two second universal wheels 503, a second connecting rod 504 fixedly connected to the connecting end of the second universal wheel 503, and a horizontal rod 505 connected between the two second connecting rods 504.

[0029] The expanding wheel assembly 5 also includes a tension spring 506 hingedly connected to the middle of the horizontal rod 505, and the end of the tension spring 506 away from the horizontal rod 505 is hingedly connected to a third recess 13 in the middle of the bottom of the box 1. The second connecting rod 504 has an L-shaped structure, and when the second connecting rod 504 is rotated outward to the maximum angle, the lowest point of the second connecting rod 504 is at the same horizontal position height as the lowest point of the walking wheel 3.

[0030] The second groove 12 in the scheme is internally provided with a shaft for hingedly rotating one end of the second connecting rod 504, when it is needed to improve the stability of the box body 1 in the vertical state, the second connecting rod 504 is rotated to the maximum angle with the shaft as the center, the end of the second connecting rod 504 connected with the shaft is in the opposite parallel state with the bottom end surface of the box body 1, then the second connecting rod 504 is transferred to the outside of the bottom of the box body 1 under the rotating action of the second universal wheel 503, thereby increasing the supporting area of the bottom of the box body 1 and improving the overall stability of the box body 1 in the vertical state.

[0031] In addition, the expansion wheel assembly 5 in the embodiment further comprises a cross rod 505 and a tension spring 506, the cross rod 505 is connected between the two second connecting rods 504, which can further improve the stability between the two second connecting rods 504, and when the second universal wheel 503 is in the outside expansion state, the tension spring 506 pulls the other structures of the expansion wheel assembly 5 towards the bottom surface of the box body 1 without loosening, and vice versa, when the second universal wheel 503 is in the inside storage state, the tension spring 506 pulls the other structures of the expansion wheel assembly 5 towards the box body 1 without loosening, thereby ensuring that the expansion wheel assembly 5 will not easily change in the two mode states, and improving the relative stability of the mode state.

[0032] It should be noted that when the expansion wheel assembly 5 is stored, the universal wheels in the expansion wheel assembly 5 are not used as walking supports of the luggage, and the storage of the expansion wheel assembly 5 does not affect the inclined dragging walking of the luggage.

[0033] Please refer to Figs. 1-4 , the luggage further comprises a telescopic pull rod 2 arranged at one end of the top of the box body 1, and the pull rod 2 is located at one side of the opening end of the enclosing member 4.

[0034] In the embodiment, when the pull rod 2 is stretched and expanded, the pull rod 2 can shield the side gap of the enclosing member 4 in the first mode state of the enclosing member 4, thereby avoiding the problem that the child cannot be protected when leaning forward by himself / herself, and further improving the safety of the child seat.

[0035] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
