[0024]Referring to FIGS. 1 to 9, the present disclosure discloses a trolley bag, which includes a bag body 100. The bag body 100 is provided with an accommodating cavity 101, and the accommodating cavity 101 is provided with a pull rod frame 200 and a shoulder strap assembly 300 positioned inside the pull rod frame 200. The shoulder strap assembly 300 includes a back pad 301 and a shoulder strap 3011 mounted on the back pad 301. The accommodating cavity 101 is provided with an opening 1011 for the shoulder strap 3011 to extend out of the accommodating cavity 101.

[0025] In this embodiment, the accommodating cavity 101 is provided on the back of the bag body 100. The pull rod frame 200 has a U-shaped structure and is provided with a retractable pull rod. The top of the accommodating cavity 101 is also open, so that when the pull rod is pulled out of the pull rod frame 200, the pull rod can extend out of the bag body 100, as shown in FIG. 8.

[0026]As shown in FIG. 1 and FIG. 3, the bag body 100 can be carried on the back through the shoulder strap 3011, thereby realizing the backpack function. By arranging the back pad 301, when the bag body 100 is lifted, the back pad 301 can support the back of the human body, so that the user can carry the case more comfortably. By arranging the shoulder strap assembly 300 inside the bag body 100, the pull rod frame 200, the back pad 301 and the shoulder strap 3011 can be on the same plane. When the bag body 100 is carried, it can be well supported. At the same time, the bag body 100 will not be more compact, thus reducing the space occupation. When the pull rod is pulled out of the bag body 100, it will not interfere with the shoulder strap assembly 300.

[0027] In an embodiment, the back pad 301 is provided with an extension end extending in a direction towards the opening 1011 for increasing the thickness of the back pad 301 and preventing the back of the human body from contacting the pull rod frame 200. The extension end extends out from the inner side of the pull rod frame 200.

[0028] By thickening the back pad 301 such that the back pad 301 can extend from the inner side of the pull rod frame 200, the back of the human body can be prevented from contacting with the pull rod frame 200 when the bag body 100 is lifted, and the comfort of users carrying the case can be further improved.

[0029] In other embodiments of the back pad 301 (not shown), the back pad 301 can cover the pull rod frame 200 while extending out of the pull rod frame 200. In this way, the pull rod frame 200 can be protected, and at the same time, the human back can be further prevented from contacting the pull rod frame 200.

[0030] Referring to FIGS. 2 and 9, the bag body 100 of the present disclosure is further provided with rigid mounting parts 102 that are detachably mounted with the rollers 500. Preferably, the mounting parts 102 are disposed at four corners of the bottom of the bag body 100. The mounting parts 102 are provided with mounting holes 1021, and the rollers 500 are provided with studs, which are inserted into and screwed with the mounting holes 1021.

[0031] In this embodiment, by providing the detachable rollers 500, when the bag body 100 needs to be used as a luggage case, the rollers 500 can be installed at the bottom of the bag body 100, and the pull rod can be pulled out from the bag body 100, so that the bag body 100 can be pulled for use, thereby further realizing the function of a trolley case.

[0032] The mounting of the rollers 500 are not limited to the above-mentioned threaded connection, and a quick disassembly structure such as clamping and magnetic attraction can be adopted, which makes the mounting of the rollers 500 simpler, more convenient and faster.

[0033] Referring to FIGS. 3 to 9, the present disclosure further discloses that a detachable mechanism is disposed between the back pad 301 and the accommodating cavity 101, the shoulder strap assembly 300 is detachably connected with the accommodating cavity 101 through the detachable mechanism, and the opening 1011 is detachably connected with the cover 400 for closing the opening 1011.

[0034] By detachably connecting the shoulder strap assembly 300 with the accommodating cavity 101, the shoulder strap assembly 300 can be detached from the accommodating cavity 101 when the backpack function is not used and switched to the trolley case function. At the same time, the cover 400 seals the opening 1011, so that the accommodating cavity 101 can form an accommodating space for storing articles.

[0035] In a preferred embodiment of the cover 400, the cover 400 is made of a flexible material and can be rolled up. The edge of the cover 400 is connected with the edge of the opening 1011 through a zipper. The side of the cover 400 facing the shoulder strap assembly 300 is provided with a receiving groove 401, and at least part of the shoulder strap 3011 can be inserted into and received by the receiving groove 401.

[0036]In this embodiment, the cover 400 is made of flexible cloth. When the cover 400 is not used, the cover 400 can be separated from the opening 1011 through the zipper and rolled down, as shown in FIG. 1. When the cover 400 is in the rolled-up state and the shoulder strap assembly 300 is not detached from the bag body 100, part of the shoulder strap can be inserted into the receiving groove 401 to be received, which makes the bag body 100 more concise.

[0037] It is worth mentioning that when the shoulder strap assembly 300 is not disassembled, the cover 400 can also be connected with the opening 1011 and closed, so that the shoulder strap assembly 300 can be shielded.

[0038] In other possible embodiments of the cover 400 (not shown), the cover 400 can also be composed of a plurality of hard plates, and two adjacent hard plates can be turned over and folded. At the same time, the cover 400 can also be connected with the bag body 100 by clamping, button connection or hook and loop bonding.

[0039]As shown in FIGS. 4 to 6, in a preferred embodiment of the detachable mechanism, the detachable mechanism includes a first connector 3012 and a second connector 3021 respectively disposed on the accommodating cavity 101 and the back pad 301. A magnetic fastener is disposed between the first connector 3012 and the second connector 3021, and the first connector 3012 is detachably connected with the second connector 3021 through the magnetic fastener. The magnetic fastener includes barbs and hook grooves respectively disposed on the first connector 3012 and the second connector 3021. Magnets are disposed on the barbs and the hook grooves, and the barbs are engaged with the hook grooves and attracted by the magnets. The barbs include a first barb 3013 and a second barb 3022 respectively disposed on the first connector 3012 and the second connector 3021. The hook grooves include a first hook groove 3014 and a second hook groove 3023 respectively disposed on the first connector 3012 and the second connector 3021. The first barb 3013 is engaged with the second hook groove 3023 and is attracted to the second hook groove 3023 by the magnet, and the second barb 3022 is engaged with the first hook groove 3014 and is attracted to the first hook groove 3014 by the magnet.

[0040] By engaging the first barb 3013 with the second hook groove 3023 and attracting them by the magnet, and engaging the second barb 3022 with the first hook groove 3014 and attracting them by the magnet, the shoulder strap assembly 300 can be installed and disassembled in the receiving cavity 101 conveniently and quickly.

[0041] Moreover, in this embodiment, the accommodating cavity 101 is also fixedly provided with a mounting plate 302 located inside the pull rod frame 200. The mounting plate 302 is located between the inner wall of the accommodating cavity 101 and the back pad 301. The first connector 3012 is disposed on the mounting plate 302, and the second connector 3021 is disposed on the back pad 301.

[0042] Moreover, both the top and bottom sides of the mounting plate 302 and the back pad 301 are provided with a first connector 3012 and a second connector 3021, so that when the shoulder strap assembly 300 is installed in the accommodating cavity 101, more connection and support positions are provided, and the connection is more stable.

[0043] By providing the mounting plate 302 in the accommodating cavity 101, when the shoulder strap assembly 300 is used, the stress on the bag body 100 is more uniform, and the stability of the connection between the shoulder strap assembly 300 and the bag body 100 is improved.

[0044] Of course, in other embodiments (not shown), the first connector 3012 can also be directly disposed on the inner wall of the receiving cavity 101, which can save the manufacturing cost.

[0045] In other possible embodiments of the detachable mechanism (not shown), the detachable mechanism may also adopt any other modes adapted for quick mounting and disassembly of the shoulder strap assembly 300, such as hook and loop bonding, snap connection, snap connection and the like.

[0046] To sum up, as can be seen from the above description, the present disclosure has achieved the following technical effects:

[0047] by providing the back pad 301, when the bag body 100 is lifted, the back pad 301 can support the back of the human body, so that the user can carry the bag more comfortably; by providing the shoulder strap assembly 300 inside the bag body 100, the pull rod frame 200, the back pad 301 and the shoulder strap 3011 can be on the same plane; when the bag body 100 is carried, it can be well supported; at the same time, the bag body 100 will be more compact, thus reducing the space occupation; and when the pull rod is pulled out of the bag body 100, it will not interfere with the shoulder strap assembly 300;

[0048] by detachably connecting the shoulder strap assembly 300 with the accommodating cavity 101, the shoulder strap assembly 300 can be detached from the accommodating cavity 101 when the backpack function is replaced by the trolley case function; at the same time, the cover 400 seals the opening 1011, so that the accommodating cavity 101 can form an accommodating space for storing things.

[0049] In the description of the present disclosure, it should be appreciated that the orientation or positional relationship indicated by orientation words such as "front, back, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom" are usually based on the orientation or positional relationship shown in the attached drawings, just for the convenience of describing the present disclosure and simplifying the description. Unless otherwise stated, these orientation words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, therefore they cannot be construed as limiting the scope of protection of the present disclosure. The orientation words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0050] For the convenience of description, spatially relative terms such as "above", "on", "on the upper surface of" and "upper" can be used here to describe the spatial positional relationship between a device or feature as shown in the drawings and other devices or features. It should be appreciated that spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation of the device depicted in the drawings. For example, if the devices in the drawings are inverted, devices described as "above" or "on" other devices or structures will be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both orientation of "above" and "below". The device can also be positioned in other different ways (rotated by 90 degrees or in other orientations), and the spatial relative description used here is explained accordingly.

[0051] In addition, it should be noted that the words "first" and "second" are used to define parts for the convenience of distinguishing the corresponding parts. Unless otherwise stated, the above words have no special meaning, and thus they cannot be construed as limiting the protection scope of the present disclosure.

[0052] What has been described above is only the preferred embodiment of the present disclosure, and it is not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and changes. Any modification, equivalent substitution, improvement and the like made within the spirit and principle of the present disclosure shall fall into the protection scope of the present disclosure.
