Description

Technical Field

[0001] This utility model relates to a luggage component, and more particularly to a connection structure between the outer shell and the side cover of a luggage. Background Technology

[0002] With the development of smart travel devices, electric suitcases that combine cargo and passenger functions are becoming increasingly popular. These products need to withstand vertical and lateral loads of 50-100kg when the user is seated, placing stringent requirements on the structural strength of the suitcase. Existing intermediate box panels are typically thin. If the side covers are directly attached to the edges of the box panels with screws, the stress area is small, resulting in an unstable connection. Furthermore, when the suitcase is under heavy load or subjected to impact, the connection is prone to tearing or screw loosening and falling off, affecting the suitcase's lifespan. The intermediate box, composed of four panels, has weak compressive and torsional resistance without effective reinforcement. During lifting or transporting heavy loads, the box is prone to deformation, leading to gaps between the side covers and the box, affecting aesthetics and sealing. In existing technologies, the docking of the side covers and the intermediate box often lacks precise positioning and guiding structures. Assembly requires repeated manual adjustments to align the screw holes, resulting in low assembly efficiency and difficulty in ensuring product consistency. Utility Model Content

Detailed Implementation

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views of the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] like Figures 1-11 As shown: This utility model discloses a connection structure between the outer shell and the side cover of a suitcase, including a middle box body 1, a strip profile 2, a left side panel 6 and a right side panel 7.

[0019] The intermediate box 1 is formed by a front plate 11, a rear plate 12, an upper plate 13, and a lower plate 14, creating an integral structure. Specifically, the front plate 11 and the rear plate 12 are positioned opposite each other, and the upper plate 13 and the lower plate 14 are positioned opposite each other. The four plates are connected by welding, gluing, or other conventional fixing methods to form a rectangular cylindrical box frame. Each plate of the intermediate box 1 has a reinforcing rib 15 extending along the width of the plate and penetrating both ends to enhance the overall rigidity and deformation resistance of the box. The reinforcing rib 15 is preferably an integrally formed protrusion structure, integrally formed with the plate using injection molding or extrusion. The end face of the reinforcing rib 15 has a threaded hole 16 for subsequent screwing and fixing.

[0020] The strip profile 2 serves as an intermediate connector, used to connect the reinforcing rib 15 of the intermediate housing 1 to the side panel of the housing. The strip profile 2 is elongated, its length matching the height of the side of the intermediate housing 1. The strip profile 2 has reinforcing rib insertion holes 3 corresponding to the positions of the reinforcing rib 15. These insertion holes 3 are grooves, their shape adapting to the end of the reinforcing rib 15. A second connecting hole (not separately shown in the figure, but located on the inner wall of the insertion hole) is provided within the reinforcing rib insertion hole 3; this second connecting hole is a through hole. During assembly, the reinforcing rib 15 is inserted into the reinforcing rib insertion hole 3, and then a screw passes through the second connecting hole and is screwed into the first connecting hole 16, thus achieving a secure connection between the strip profile 2 and the plate of the intermediate housing 1. This connection method provides positioning guidance through the insertion of the reinforcing rib 15, improving assembly accuracy and efficiency. Simultaneously, the screwed fixation enhances the connection strength, avoiding the tearing risk caused by directly screwing onto thin plates.

[0021] The side panels of the enclosure include a left side panel 6 and a right side panel 7, which respectively cover the left and right openings of the middle enclosure 1 to form a complete enclosure shell. Multiple side panel connecting ears 8 are provided on the inner edges of the left side panel 6 and the right side panel 7. Each side panel connecting ear 8 is an inwardly protruding ear-shaped structure, and each side panel connecting ear 8 has a connecting hole 9, which is a through hole for screw fixing.

[0022] Furthermore, the strip profile 2 is provided with a side plate connection hole 5 corresponding to the position of the connection hole 9 inside the side plate connection lug 8 of the left side plate 6. This side plate connection hole 5 is a threaded hole. When assembling the left side plate 6, a screw is passed through the connection hole 9 and screwed into the side plate connection hole 5 to realize the connection between the strip profile 2 and the left side plate 6. This connection method utilizes the side plate connection lug 8 to expand the stress-bearing area, thereby improving the stability of the connection and its resistance to lateral loads.

[0023] Similarly, the strip profile 2 is also provided with a side plate connection hole 5 corresponding to the position of the connection hole 3 9 inside the side plate connection lug 8 of the right side plate 7. When assembling the right side plate 7, the strip profile 2 is connected to the right side plate 7 by screwing through the connection hole 3 9 and screwing it into the side plate connection hole 5.

[0024] In practical applications, this connection structure is suitable for products such as electric suitcases that need to withstand high loads. The assembly process is as follows: First, align the reinforcing rib holes 3 of the strip profile 2 with the ends of the reinforcing ribs 15 of each plate of the middle box body 1, insert them, and fix them with screws; then, align the side plate connecting ears 8 of the left side plate 6 and the right side plate 7 with the side plate connecting holes 5 of the strip profile 2, and tighten them with screws. Through the cooperation of the reinforcing ribs 15 and the strip profile 2, this structure forms a continuous load transfer path, improving the box body's resistance to compression, torsion, and impact. At the same time, the design of the side plate connecting ears 8 provides precise positioning, simplifies the assembly process, and improves production efficiency and product consistency.

[0025] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no conflict in the mechanism, the features in the embodiments disclosed in the present invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
