Description

Technical Field

[0001] This utility model relates to the field of luggage technology, specifically to an assembly structure for a folding structure of a suitcase handle. Background Technology

[0002] The handles of existing suitcases adopt an assembly structure, including handle strips, handle bases, and bottom plates. The bottom plate is assembled with the suitcase body and has its own mounting groove for the handle base to be installed. The handle base provides assembly connection for the two ends of the handle strip.

[0003] The problem with existing technology is that when consumers lift a suitcase, they need to reach their hands into the gap between the handle and the suitcase shell to grip the handle and pull it. To facilitate this, existing technologies usually leave a gap between the handle and the suitcase shell, or design the handle as an arched structure. This results in a noticeable gap between the suitcase and the handle even when the suitcase is not being lifted, causing a localized protrusion and crack in the overall shape of the suitcase, thus limiting the diversity of suitcase design.

[0004] Furthermore, due to the differences in the size of consumers' hands, it is difficult to ensure a proper fit with the reserved gap. If the reserved gap is too large, it will further affect the appearance, while if the reserved gap is too small, it will affect the lifting feel for consumers.

[0005] Furthermore, after carrying a suitcase for a certain period of time, consumers' hands become sweaty and slippery due to the exertion, which can lead to discomfort during use.

[0006] Therefore, it is necessary to improve the design of the luggage handle structure by using a folding structure to make the handle strip expandable, retractable and ventilated, in order to overcome the problems of making it easier for users to lift and grip the handle strip and expand the scope of the overall shape design of the luggage. Utility Model Content

[0007] To address the shortcomings of the aforementioned technologies, this invention provides a folding structure for a suitcase handle.

[0008] The technical solution of this utility model is: a folding structure for a suitcase handle, including a handle strip, a pair of handle seats, a pair of hinge pieces, a base plate, and several pins. The handle seat includes a fixed end face that is connected to the suitcase shell and the base plate, and a connecting end face that faces the outside of the suitcase. The connecting end face is provided with a hinge joint facing the handle strip side, and the hinge joint is provided with a first hinge hole.

[0009] The hinge component includes a first arc end and a second arc end, both of which are provided with a second hinge hole. The first arc end is connected to the hinge joint by a pin hinge.

[0010] The handlebar has symmetrical storage grooves at both ends corresponding to the handlebar seat position. The storage groove includes a hinge end and a flat end. The hinge end is provided with a third hinge hole and is connected to the second arc end by a pin hinge. The first arc end of the handlebar moves into the storage groove and fits against the flat end, or moves out of the storage groove.

[0011] A further feature of this invention is that the connecting end face is provided with a relief groove adapted to the second arc end, and when the hinge member is parallel and fitted to the connecting end face, the hinge joint portion is embedded in the relief groove.

[0012] A further feature of this invention is that the hinge joint and the hinge end are provided with a first slot and a second slot respectively corresponding to the width of the first arc end and the second arc end, and the first slot and the second slot are provided with rotating grooves adapted to the first arc end and the second arc end.

[0013] A further feature of this invention is that the hinge component has an "8" shaped structure.

[0014] A further feature of this invention is that the cross-sectional profile of the connecting end face is adapted to the cross-sectional profile of the receiving groove, and when the hinge component is parallel and fitted to the connecting end face, the connecting end face covers the opening of the receiving groove.

[0015] Further features of this utility model: The handle bar includes a frame and a covering. The frame includes a crossbeam and connecting seats at both ends of the crossbeam. The end face of the frame away from the suitcase is provided with a groove. The covering covers the frame and is provided with an opening that exposes the storage groove.

[0016] A further feature of this invention is that the suitcase shell has a pair of mounting openings, the bottom plate is located inside the suitcase shell, and the bottom plate has a mounting groove that is adapted to the outline of a pair of handlebar seats, and the opening of the mounting groove is aligned with the pair of mounting openings. The fixed end face of the handlebar seat passes through the mounting hole and is assembled and fixed to the handle bar and the bottom plate respectively.

[0017] A further feature of this invention is that the covering has several ventilation holes on the side facing the suitcase.

[0018] A further feature of this invention is that the covering is provided with an antibacterial coating, an antibacterial fabric, or a sweat-proof material.

[0019] The beneficial effects of this utility model are as follows: Through the structural design of the storage groove, hinge joint and hinge component, the handle bar can be tightly fitted to the handle seat (i.e., fitted to the suitcase shell) when the hinge component is folded, as shown in the attached figure of the specification. The hinge component is adapted to be embedded in the storage groove, so that the gap between the two is minimized under normal conditions. Moreover, the connecting end face of the handle seat covers the groove opening of the storage groove, forming an integrated structure.

[0020] When it is necessary to lift the suitcase, the consumer lifts the handle bar, and the hinge flips open, as shown in the attached diagram of the instruction manual, expanding the space between the handle bar and the suitcase shell for the hand to reach in.

[0021] The design of this structure ensures that even with a larger pre-set hand depth, the seamless aesthetics of the suitcase will not be compromised when folded. It adapts to different hand sizes, providing a comfortable lifting experience while supporting the seamless design of the suitcase.

[0022] Meanwhile, the handlebar cover and frame are designed separately for easy detachment and replacement. This allows for convenient replacement of the easily worn gripping parts (cover), while the frame itself meets the strength requirements for tensile and bending resistance. Several ventilation holes are provided on the side of the cover facing the suitcase, allowing air to circulate through the gaps when gripping and preventing sweating from tight gripping.

[0023] The materials and coating designs of the covering components offer various functions. For example, textiles containing silver ions or other antibacterial agents achieve antibacterial effects by disrupting bacterial cell structures, with an antibacterial rate of up to 99%. Surface antibacterial function is achieved by spraying nano-level antibacterial coatings (such as titanium dioxide or quaternary ammonium compounds). Silicone materials with added anti-slip textures not only improve grip comfort but also reduce hand sweat residue. Their hydrophobic properties allow for rapid sweat evaporation, reducing odor. Combining ABS / PC substrates with sweat-resistant additives (such as bamboo charcoal fiber or mineral microparticles) enhances breathability while maintaining structural strength, reducing hand slippage issues, and so on.
