Description

Technical Field

[0001] The utility model relates to the technical field of bags and suitcases, and more specifically to a top flip-cover type trolley case. Background Art

[0002] As people travel more and more frequently, trolley cases have become popular as a type of case used to carry personal belongings when people travel. However, the trolley cases commonly available on the market often do not have the function of accommodating children. When children sit on the trolley case, it is difficult for them to maintain their balance and they may fall, posing a safety hazard. In this way, users can only push the stroller with one hand and the trolley case with the other hand, which is very inconvenient.

[0003] In order to solve the above problems, some trolley cases with backrests are now available on the market, such as a suitcase with a handle and a backrest with patent authorization announcement number CN219762666U, which includes a three-section tie rod, a backrest, two-section handles, a handle shaft, a box body and its rollers. The handle is divided into two sections, and the two sections are connected by a telescopic tie rod. The backrest is fixed on the second section of the tie rod, and the height can be adjusted up and down with the tie rod. When in use, the suitcase can be pushed and pulled by the tie rod and the handle, and children can sit on the top of the box body, holding the handle and leaning against the backrest, so that children can sit and reduce the risk of children falling. However, the structure of the suitcase combining the handle and the backrest is relatively complex and costly, and the tie rods are set on both sides of the box body with a large spacing. In addition, there are some trolley cases with flip-up backrests on the market, but the backrest is installed on the rear box body, which will interfere with the pull rod installed on the rear box body. The pull rod must be retracted to close the backrest, and the backrest needs to be flipped 180 degrees before use. When the backrest is not in use, since it is attached to the back of the rear box body, the width of the rear box body is greatly increased, affecting the proportional division of the front and rear boxes.
