[0002] This utility model relates to the field of luggage technology, and in particular to a luggage body and a luggage box. Background Technology

[0003] Suitcases typically serve to hold and facilitate the movement of belongings. However, considering the fatigue that can occur when users pull a suitcase while walking, suitcases that allow users to sit and rest or even ride around are gradually appearing on the market.

[0004] In existing technology, suitcases are typically made of two hinged halves that snap together to form a complete suitcase, with zippers or other mechanisms used to control opening and closing. The overall structural strength of these suitcases is relatively poor; when a user sits on them, the zippers or other components may break or the suitcase may dent, compromising its storage function or causing shape defects. Utility Model Content

[0005] To overcome the technical problem that the existing suitcase body is not strong enough and cannot meet the user's riding needs, this utility model provides a suitcase body, which includes:

[0006] A panel assembly, wherein the panel assembly includes a panel that encloses a receiving cavity, and openings are provided at opposite ends of the receiving cavity;

[0007] A side cover assembly includes two side cover bodies that can cover the openings at both ends and enclose the surrounding panel to form a closed space. Each opening on both sides is provided with a first connecting structure. The first connecting structure includes a strip-shaped frame that is circumferentially disposed on the inner wall of the opening on both sides. The strip-shaped frame is attached to and fixedly connected to the inner wall of the surrounding panel. The two side cover bodies are provided with a second connecting structure corresponding to the first connecting structure. The strip-shaped frame and the second connecting structure can be connected and fixed to each other.

[0008] Furthermore, a first engagement plane is provided on the side of the strip frame away from the inner wall of the enclosure, and the second connection structure includes a fixing part, the fixing part including a second engagement plane that can be tightly engaged with the first engagement plane.

[0009] Furthermore, the strip-shaped frame has multiple hollow openings along its length.

[0010] Furthermore, the enclosure assembly also includes at least two spaced-apart fixing posts, which are fixedly connected to the enclosure and perpendicular to the strip frame. The strip frame is provided with fixing holes and is fixedly connected to the fixing posts through the fixing holes.

[0011] Furthermore, the enclosure assembly also includes reinforcing ribs, which are fixedly connected to the inner wall of the enclosure and are perpendicular to the fixed column.

[0012] Furthermore, the enclosure panel, the reinforcing rib, and the fixing column in the enclosure panel assembly are integrally injection molded.

[0013] Furthermore, at least one of the side cover plates is provided with a switch door, which can open or close the receiving cavity space.

[0014] Furthermore, the strip-shaped frame includes a first frame surface perpendicular to the first joint plane, the first frame surface being located on the side of the strip-shaped frame close to the adjacent side cover plate, the fixing part including a stepped structure, the stepped structure including a second joint plane and a first stepped surface perpendicular to the second joint plane, the first frame surface being able to be tightly joined with the first stepped surface.

[0015] Furthermore, the side cover plate is integrally injection molded.

[0016] In another aspect, this application provides a suitcase that uses the aforementioned suitcase body, and the suitcase further includes a power component, a steering component, and a pulley assembly disposed on the suitcase body. The power component can drive the pulley assembly to rotate, and the steering component can control the direction of movement of the suitcase body.

[0017] Beneficial effects:

[0018] This application provides a suitcase body, including a side panel assembly and a side cover assembly. The side panel assembly includes a side panel that encloses a receiving cavity, with openings on opposite sides of the cavity. The side cover assembly includes two side cover bodies that cover the openings and, together with the side panel, form a closed space. Each opening has a first connecting structure, which includes a strip-shaped frame annularly disposed on the inner wall of the opening. The strip-shaped frame is fitted to and fixedly connected to the inner wall of the side panel. A second connecting structure corresponding to the first connecting structure is provided on each side cover body, and the strip-shaped frame and the second structure can be connected and fixedly connected to each other. The first connecting structure, while connecting the side cover bodies, also provides support for the side panel assembly under stress, distributing the force to the side panel and preventing deformation. Meanwhile, since the side panel is connected to the strip frame through the second connecting structure, it can also help the strip frame share the force, resulting in high overall structural strength of the suitcase and ensuring that the suitcase structure will not be damaged when the user sits on top of the side panel.

[0019] This application also provides a suitcase that uses the aforementioned suitcase body and can maintain its structural stability when the user is riding on it. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] like Figures 1-6 As shown, this utility model provides a suitcase body, which includes a surround panel assembly and a side cover panel assembly. The surround panel assembly includes a surround panel 1, which encloses a receiving cavity, and openings are provided on opposite sides of the receiving cavity. The side cover panel assembly includes two side cover panels 2, which cover the openings and together with the surround panel 1 form a closed space. A first connecting structure is provided at each of the two openings. The first connecting structure includes a strip-shaped frame 3 that is arranged around the inner wall of the opening and is fixedly connected to the inner wall of the surround panel 1. A second connecting structure is provided on the side cover panel 2, corresponding to the position of the first connecting structure, and the strip-shaped frame 3 is connected and fixedly connected to the second connecting structure.

[0030] It is understandable that the side panel 1 is located between the two side cover panels 2, serving as an intermediate structure. When a user sits on the suitcase, they are essentially placing most of their body weight on the side panel 1. Therefore, strengthening the structure of the side panel 1 effectively prevents damage to the suitcase. While the first connecting structure connects the side cover panels 2, the strip-shaped frame 3 is fitted and fixed to the inner wall of the side panel 1. When the side panel 1 is under stress, the strip-shaped frame 3 provides support for the side panel assembly, distributing the force and preventing deformation. The overall structural strength of the suitcase is high, ensuring that the suitcase structure will not be damaged when the user sits on top of the side panel 1.

[0031] Furthermore, a first engagement plane 31 is provided on the side of the strip frame 3 away from the inner wall of the enclosure 1. The second connecting structure includes a fixing part 4, which includes a second engagement plane 411 that can be tightly engaged with the first engagement plane 31. The strip frame 3 includes two parallel planes, one of which is fixed to the inner wall of the enclosure 1. The strip frame 3 in contact with the inner wall of the enclosure 1 can better distribute the force on the enclosure 1. The other plane serves as the first engagement plane 31, and the second engagement plane 411 in the fixing part 4 can engage with the first engagement plane 31. It is understandable that the direction of the side cover 2, which is close to or away from the enclosure assembly, is parallel to the first joint plane 31 and the second joint plane 411. When the first joint plane 31 and the second joint plane 411 are engaged, they can play a positioning role in the installation of the side cover 2. In addition, the strip frame 3 is arranged around the inner wall of the enclosure 1. The normal of its first joint plane 31 is oriented towards the axis of the receiving cavity. When it is engaged with the second joint plane 411, it will surround the fixing part 4 and abut against the fixing part 4. That is, when the first joint plane 31 and the second joint plane 411 are engaged, they play a circumferential limiting role in the side cover 2, so as to prevent the side cover 2 from shaking circumferentially after installation and affecting the quality of the suitcase.

[0032] Furthermore, a threaded hole is provided on the first mating plane 31, and a through hole is provided on the second mating plane 411. A threaded connector 7 is passed through the through hole and threadedly connected to the threaded hole, which can fix the fixing part 4 to the strip frame 3, thereby realizing the fixed connection between the side cover plate 2 and the surrounding plate 1. In some other embodiments, the strip frame 3 and the fixing part 4 can also be implemented in other ways, such as welding connection, snap-fit ​​connection, etc., which are not limited in this embodiment.

[0033] Furthermore, the strip-shaped frame 3 has multiple perforations 33 along its length. The openings of the perforations 33 face the side cover plate 2, ensuring sufficient contact area between the strip-shaped frame 3 and the surrounding plate 1, and evenly distributing the force within the surrounding plate 1. The strip-shaped frame 3 is a metal frame, and the perforations 33 effectively reduce its weight, improving the user experience when using the suitcase. Simultaneously, the perforations 33 have a capsule-shaped structure; this perforated shape reduces internal stress concentration, helping the metal frame structure maintain stability and prevent deformation.

[0034] Furthermore, the enclosure assembly also includes at least two spaced-apart fixing posts 5. The fixing posts 5 are fixedly connected to the inner wall of the enclosure 1 and perpendicular to the strip frame 3. The strip frame 3 has fixing holes and is fixedly connected to the fixing posts 5 through these holes. That is, the fixing posts 5 are directly fixedly connected to the enclosure 1, and the strip frame 3 is connected to the end of the fixing posts 5 through the fixing holes. Simultaneously, the strip frame 3 and the fixing posts 5 can be mutually fixed through threaded connectors 7. It can be understood that the enclosure 1 as a whole can be considered as an end-to-end ring structure. When a customer sits on the enclosure, pressure is applied towards the center of the ring structure. The fixing posts 5 are perpendicular to the strip frame 3, meaning they extend along the width of the ring structure and are spaced apart along its length. When the enclosure 1 is subjected to pressure, deformation will cause a change in the distance between adjacent fixing posts 5. Since the fixing posts 5 are connected by a rigid metal frame, the distance between the fixing posts 5 cannot change unless the metal frame deforms, thus preventing deformation of the enclosure 1. It is understood that the strip frame 3 in the above connection method can be conveniently and quickly connected and installed through the fixing post 5. Therefore, the strip frame 3 can be processed and produced separately, and then installed after processing and production, avoiding the difficulty of integral molding of the surrounding panel assembly due to too many holes. In some other embodiments, the strip frame 3 can also be fixed to the surrounding panel 1 by snap-fit, the surrounding panel 1 is provided with threaded holes, and the strip frame 3 is provided with through holes and threaded connectors 7 are connected to the threaded holes through the through holes, etc. This embodiment does not limit this.

[0035] Furthermore, the enclosure assembly also includes reinforcing ribs 6, which are fixedly connected to the inner wall of the enclosure 1 and are perpendicular to the fixing column 5. The reinforcing ribs 6 in the enclosure 1 are integrally formed with the enclosure 1 body, and when the enclosure 1 is under stress, the ribs of the reinforcing ribs 6 can promptly share the stress. The reinforcing ribs 6 are perpendicular to the fixing column 5, meaning they are arranged along the length of the annular structure, thus strengthening the compressive strength of the enclosure 1. In this embodiment, one or more reinforcing ribs 6 are provided. It is understood that the more reinforcing ribs 6 there are, the stronger the structure of the enclosure 1. In actual production, the number of reinforcing ribs 6 can be modified according to actual needs; no further limitations are made here.

[0036] Furthermore, the enclosure panel 1, reinforcing rib 6, and fixing post 5 in the enclosure panel assembly are integrally injection molded. Using integral injection molding to produce the enclosure panel 1, reinforcing rib 6, and fixing post 5 together reduces the assembly steps of the enclosure panel assembly. The enclosure panel 1, reinforcing rib 6, and fixing post 5 can be made of rigid plastic or other composite materials; this embodiment does not limit this.

[0037] Specifically, at least one side cover plate 2 is provided with a switch door, which can open or close the accommodating cavity space. The suitcase needs to have the function of opening or closing the accommodating space, and the suitcase body panel 1 in this application needs to meet certain pressure resistance requirements. Providing a switch door on the panel 1 might affect the structural strength of the panel 1; therefore, a switch door is provided on the side cover plate 2. Furthermore, the switch door is provided within the surrounding area of ​​the fixing part 4 in the side cover plate 2, and a locking component is provided between the side cover plate 2 and the panel 1. The locking component is located at the top of the suitcase body, and the user can open or close the switch door by operating the locking component from the top.

[0038] Furthermore, the strip-shaped frame 3 includes a first frame surface 32 perpendicular to the first joint plane 31. The first frame surface 32 is located on the side of the strip-shaped frame 3 closest to the adjacent side cover plate 2. The fixing part 4 includes a stepped structure 41, which includes a second joint plane 411 and a first stepped surface 412 perpendicular to the second joint plane 411. The first frame surface 32 can be tightly joined with the first stepped surface 412. After the stepped structure 41 is joined with the strip-shaped frame 3, it will partially surround the strip-shaped frame 3, that is, the stepped structure 41 can snap the strip-shaped frame 3 into place at the stepped opening. The joining effect between the first joint plane 31 and the second joint plane 411 is not described in detail here. When the side cover plate 2 is placed over the opening of the enclosure 1, the tight joining of the first frame surface 32 and the first stepped surface 412 can play a positioning effect on the depth of the side cover plate 2, preventing the side cover plate 2 from being placed too deep and affecting the volume of the receiving cavity. Furthermore, when the side cover plate 2 is subjected to pressure towards the interior of the cavity, the first frame surface 32 and the first stepped surface 412 can share this pressure, preventing excessive shear stress on the threaded connector 7 between the strip frame 3 and the fixing part 4, and reducing structural damage caused by stress concentration. Moreover, the fixing part 4 is composed of multiple Z-shaped structural members arranged circumferentially along the inner edge of the side cover plate 2, and the portion of the Z-shaped structural members extending into the strip frame 3 constitutes the stepped structure 41. Using multiple Z-shaped structural members instead of a continuously arranged stepped structure 41 reduces the amount of material used in the fixing part 4, thereby lowering production costs.

[0039] Furthermore, the side cover plate 2 is integrally injection molded. Similar to the aforementioned enclosure plate 1, reinforcing rib 6, and fixing post 5, the integral injection molding of the side cover plate 2 reduces assembly steps and facilitates box production. The side cover plate 2 can be made of rigid plastic or other composite materials; this embodiment does not limit this.

[0040] This embodiment also provides a suitcase, which includes the suitcase body described above, and further includes a power component, a steering component 8, and a pulley component 9. The pulley component 9 is disposed at the bottom of the suitcase body, and the power component is installed inside the suitcase body and is pulsatorically connected to the pulley component 9. The steering component 8 includes a steering rod installed on the side of the suitcase body and a steering wheel located at the bottom of the suitcase body, with the steering rod and the steering wheel fixedly connected. A user can straddle the suitcase with their legs positioned on either side of the side cover 2. After activating the power component and operating the steering component 8, the user can use the suitcase for transportation.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
