Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0024] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0025] As the instruction manual Figure 1-7As shown, the present invention discloses a trolley case that is easy to install, comprising a case body 1, a trolley assembly 2, and a flexible bag layer 3. The case body of the prior art has a sealed receiving cavity formed therein. The case body is also provided with an openable and closable opening for communicating with the sealed receiving cavity. The case body can be configured with a front opening or an opening located in the middle of the case body.

[0026] When the box body has a front opening, the sealed receiving cavity may only accommodate a large bag layer, serving as the primary storage space. When the box body has a central opening, the box body is a left-right structure, and the sealed receiving cavity is composed of two connected half-shells, each of which has a bag layer disposed within its interior. In some embodiments, the bag layers within the two half-shells have a connected portion, allowing them to function as a single unit during installation and removal.

[0027] Furthermore, in order to facilitate convenient assembly, the present invention adopts the following technical solutions, including a first pull rod hole 13 provided at the upper end of the box body 1, and a limiting portion 12 provided on the inner side of the lower end corresponding to the position of the first pull rod hole 13; the pull rod assembly 2 includes two retractable pull rods 21 and a handle 22 connected to the pull rods; a base 23 is provided at the bottom of the pull rod 21 for connection with the box body 1; the position of the base 23 is limited by the limiting portion; the bottom of the pull rod 22 passes through the first pull rod hole 13 and is connected to the base 23; the bag layer 3 is provided in the box body 1 and is detachably attached to the inner wall of the cavity of the box body 1. During installation, the box body 1, the pull rod assembly 2 and the bag layer 3 can all be in a finished product state or a semi-finished product state, so that the installation process is the last step or a step near the end of making a trolley case. The installation process begins by aligning the base 23 with the stopper to securely connect the base to the box body 1. Next, two pull rods 21 with handles 22 are inserted from the outside into the first pull rod holes 13 and then securely connected to the base 23, completing the installation of the pull rods 21. Finally, the bag layer is attached to the inner wall of the box body cavity using snaps or Velcro, completing the storage space. Similarly, the bag layer also has an opening that serves the same function as the box body.

[0028] The first tie rod hole 13 is positioned opposite the stopper, ensuring horizontal and accurate positioning of the tie rod 21. A properly installed tie rod 21 ensures smooth extension and prevents deformation, while also providing excellent force transmission, ensuring uniform force distribution throughout the entire tie rod case. The bag layer 3 eliminates conventional methods of securing the bag body 1, such as sewing or hot pressing, and instead utilizes a detachable connection for easy replacement and cleaning.

[0029] Furthermore, the utility model discloses a trolley case with a left-right structure and a wide trolley, wherein the case body 1 includes a left shell 11 and a right shell 12; a plurality of ear hooks 14 are distributed on the inner wall of the cavity formed by the connection of the left shell 11 and the right shell 12, and the ear hooks 14 are provided with a card hole 140 for the bag layer 3 to be snapped in. The upper end of the right shell 12 is also provided with a handle groove 120 that runs through the length direction of the right shell; the length of the handle 22 is equivalent to the length of the right shell 12, and it belongs to the existing wide trolley on the market; the first trolley hole 13 is provided at the bottom of the handle groove 120. The bag layer 3 can be pre-processed into a single body structure. The single body structure means that there is an integral or fixed connection between the two half-cavity fabrics contained in the left shell 11 and the right shell 12.

[0030] Furthermore, in this embodiment, the bag body layer 3 includes a left bag body 31 and a right bag body; the ear hook portion 14 is distributed on the inner side of the connection periphery of the left shell 11 and the right shell 12; the outer side walls of the left bag body 31 and the right bag body are provided with corresponding positions with hooks 32 that can be extended into the clamping hole 140 for clamping.

[0031] Furthermore, the limiting portion is mainly used to facilitate the positioning and installation of the base 23. The limiting portion of this embodiment is a pair of first baffles 151 and second baffles 152 positioned opposite each other on the inner side of the lower end of the right shell 12; the base 23 is restrained between the first baffle 151 and the second baffle 152 to limit its left and right movement and ensure precise positioning in the vertical direction; a groove is provided at the bottom of the base 23; the groove can be used for the first baffle 151 or the second baffle 152 to enhance the positioning strength. After the base 23 is restrained by the limiting portion, it also needs to be fixed to the right shell 12 by screws. As shown in the accompanying drawings of the specification, when the fastening screws are used for screw connection in this embodiment, installation errors may occur, affecting the precise positioning of the base 23 in the front and back directions, so the side of the base 23 is also provided with a third baffle 231 that is restrained by the first baffle 151 or the second baffle 152.

[0032] Furthermore, this embodiment includes a charging dock assembly 4, allowing users to charge their luggage while towing it. The right housing 12 defines a charging dock recess 121 for mounting the charging dock assembly. This recess 121 includes a wire hole 122 that leads to the bag layer. The charging dock recess 121 is located at the bottom of the handle recess 120, adjacent to the first pull rod hole 13. The charging dock assembly 4 includes an outer housing 41, a charging port 42, and a wire 43 connected to the bottom of the charging port. The wire 43 connects to the charging device within the bag layer 3 through the wire hole 122. The outer housing 41 also defines a second pull rod hole 410 for inserting a pull rod. The second pull rod hole 410 is located opposite the first pull rod hole 13. During installation, one of the two pull rods 21 is first inserted into the second pull rod hole 410, connected to the outer housing 41 with the charging port 42 and wire 43, and then inserted into the first pull rod hole 13. The outer shell 41 slides into the charging seat groove 121 along the installation of the pull rod 21 and is fastened to the right shell 12 with screws, which is easy to install.

[0033] Furthermore, the left and right housings 11 and 12 include end covers and surrounding walls. Taking the right housing 12 as an example, the periphery of the end cover 123 of the right housing is provided with a groove 124 that surrounds the periphery. One side of the surrounding wall 125 engages with the groove 124 and is fastened to the end cover 123 via screws. This housing structure facilitates the processing and assembly of the housing. Those skilled in the art will appreciate that various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the scope of protection of the claims of this utility model.
