Therefore, at present, in many of the suitcases available on the market, a dedicated storage space (i.e., a storage bag) for storing laptops is provided for placing travel supplies and laptops. The storage bag is usually installed inside or outside the suitcase and has a buffer structure of a certain thickness filled with sponge, shockproof material, etc. so that the articles will not be damaged by collision during the transportation process. In addition, many storage bags are equipped with open-end fasteners and fixed belts to fix the position of the articles and serve as anti-slip devices.

Summary of the Invention

Problems to be Solved by the Invention

[0003] However, most suitcases with conventional storage bags employ a fixed structure. That is, the storage bag is directly attached to or permanently linked to the suitcase body, making it difficult to remove quickly or easily. This design presents some inconveniences in actual use. First, when a user needs to take items out of the suitcase, they often have to open the entire suitcase, increasing the complexity of the operation. It is also inconvenient to open the suitcase in public places or confined spaces. Second, when a user wants to carry items from the storage bag, they have to carry the entire suitcase because the storage bag cannot be quickly and independently removed, and its large volume makes it inconvenient to carry. Furthermore, fixed storage bags occupy space inside the suitcase even when not in use, reducing the overall flexibility of storage. Therefore, providing a removable storage bag structure that also offers good protection in order to improve the convenience and flexibility of suitcase use has been a pressing issue in this field.

[0004] This invention was made in view of the above-mentioned conventional problems. To solve the above problems, the main objective of this invention is to provide a suitcase having a quick-release storage bag structure that can solve the problem that conventional storage bags inside suitcases cannot be removed, making it inconvenient to take out items and inconvenient to carry. [Means for solving the problem]

[0005] To achieve the above objective, a suitcase according to one aspect of the present invention comprises a case having an internal storage space, a storage bag installed within the storage space of the case, and a first quick-release assembly member having a first fixing member and a first movable member, wherein the first fixing member is fixed to the inner edge of the case, and the first movable member is installed at one end of the storage bag and is detachably connected to the first fixing member, thereby detachably connecting the storage bag to the case. [Effects of the Invention]

[0006] This invention offers the following advantages: By enabling quick attachment and detachment of the storage bag to the suitcase body, this invention significantly improves usability. Furthermore, the quick-release structure allows the storage bag to be securely fixed to the suitcase while also providing the advantage of high-speed attachment and detachment. This not only maintains the safety and stability of the contents during transport but also avoids the limitations imposed by conventional fixed structures, effectively improving the overall practicality and versatility of the suitcase.

[Figure 8] This is a cross-sectional view showing a suitcase according to a preferred third embodiment of the present invention. [Modes for carrying out the invention]

[0009] The present invention will be described below through embodiments of the invention, but these embodiments are not intended to limit the scope of the invention covered by the utility model registration claims. Furthermore, not all combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0010] (First embodiment) First, a suitcase having a quick-release storage bag structure according to a preferred first embodiment of the present invention will be described with reference to Figures 1 to 3.

[0011] A suitcase having a quick-release storage bag structure according to a preferred first embodiment of the present invention mainly comprises a case 10, a storage bag 20, a first quick-release assembly member 30, and a second quick-release assembly member 40. Each of these will be described below.

[0012] The case 10 has a storage space 11 for accommodating articles, and the storage space 11 has an opening 12 on one side facing the front of the case 10 that communicates with the storage space 11. In this embodiment, the case 10 further includes a front cover 13 rotatably positioned on one side of the case to cover the opening 12. Due to its small volume, the front cover 13 primarily acts to close the opening 12 of the storage space 11 of the case 10. In this way, when the front cover 13 is open, the storage space 11 is exposed for the user to put articles in and take them out. When the front cover 13 is in the position of covering the storage space 11 of the case 10, at least one lock positions the front cover 13 on the front of the case 10. Furthermore, a concave ring 14 is formed on the inner edge of the case 10 and is positioned around the opening 12 of the storage space 11 and extends toward the center of the storage space 11.

[0013] The storage bag 20 is connected to the case 10 by a first quick-release assembly member 30 and a second quick-release assembly member 40, and is detachably installed within the storage space 11 of the case 10. The storage bag 20 has a bag body 21, a storage tray 22, and a fixing part 23. The bag body 21 is a thin plate-like member, and its material includes, but is not limited to, materials with cushioning properties such as EVA hard case, sponge, mesh, nylon, polyester fiber, and leather. The storage tray 22 is installed on one side of the bag body 21 and is used to store the user's daily necessities or digital devices such as a laptop computer, tablet terminal, or mobile phone. In this embodiment, the storage bag 20 has only one storage tray 22, but in other embodiments, the storage bag 20 can have multiple storage trays 22 attached simultaneously, allowing multiple items to be stored at the same time according to the user's needs. One end of the fixing part 23 is connected to the bag body 21, and the other end is connected to the storage tray 22, and is used to secure the digital device in the storage tray 22.

[0014] In this embodiment, the storage bag 20 is adjacent to the front cover 13.

[0015] The first quick-release assembly member 30 is installed on the upper side of the case 10 and the storage bag 20 and has a first fixing member 31 and a first movable member 32. The first fixing member 31 is fixed to the inner edge of the case 10. The first movable member 32 is installed at one end of the storage bag 20 and is detachably connected to the first fixing member 31, so that the storage bag 20 is detachably connected to the case 10. Specifically, the first fixing member 31 is installed on the inner edge of the concave ring 14 of the case 10 and has an engagement seat 33 in its center that protrudes in the direction of the first movable member 32.

[0016] The first movable member 32 has an outer housing 34, a control member 35, and a fixed base 36. Inside the outer housing 34, there is a movable space 340, and on one side, there is an engagement hole 341 communicating with the movable space 340. When the first fixing member 31 is connected to the first movable member 32, the engagement seat 33 is inserted into the engagement hole 341 of the outer housing 34. Inside the engagement seat 33 and the outer housing 34, there are respectively provided neodymium magnets (not shown). When the engagement seat 33 is inserted into the engagement hole 341 of the outer housing 34, the two neodymium magnets are mutually attracted to form a fixed state.

[0017] The control member 35 is installed in the movable space 340 of the outer housing 34 and is used to be operated to move between a first position and a second position. One end of the control member 35 has an inclined surface 350, and the inclined surface 350 has an upper part 350a and a lower part 350b. Since the horizontal distance between the lower part 350b and the first fixing member 31 is closer than the horizontal distance between the upper part 350a and the first fixing member 31, when the control member 35 moves from the first position to the second position, the inclined surface 350 acts on the engagement seat 33 so that the engagement seat 33 moves in a direction away from the outer housing 34.

[0018] One side of the first fixing member 31 has a first hook portion 310. One side of the control member 35 has a second hook portion 351 corresponding to the first hook portion 310. When the control member 35 is located at the first position, the second hook portion 351 is engaged with the first hook portion 310. When the control member 35 is located at the second position, the second hook portion 351 is separated from the first hook portion 310.

[0019] At the bottom of the control member 35, there is a pulling-out portion 352 extending from the bottom of the outer housing 34 for the user to pull so as to drive the control member �5 to move from the first position to the second position.

[0020] The fixed base 36 is installed on one side of the first fixing member 31 of the outer housing 34 and fixed to one end of the storage bag 20, and is used to fix the outer housing 34 to the storage bag 20.

[0021] The second quick-release assembly member 40 is installed on the bottom sides of the case 10 and the storage bag 20 and has a second fixed member 41 and a second movable member 42. The second fixed member 41 is installed at one end of the first fixed member 31 inside the case 10. The second movable member 42 is installed at one end of the first movable member 32 of the storage bag 20 and is removably connected to the second fixed member 41.

[0022] In this embodiment, one of the second fixed member 41 and the second movable member 42 has a magnetic buckle protrusion 43, and the other has a magnetic buckle recess 44. When the second movable member 42 is coupled to the second fixed member 41, the magnetic buckle protrusion 43 is fitted into the magnetic buckle recess 44 to form an engaged state.

[0023] According to the above-described structural configuration, as shown in Figures 4 and 5, when the storage bag 20 according to this embodiment is installed in the storage space 11 of the case 10, the first movable member 32 of the first quick-release assembly member 30 is connected to the first fixing member 31 of the case 10, and the second movable member 42 of the second quick-release assembly member 40 is connected to the second fixing member 41 of the case 10, thereby enabling the storage bag 20 to be fixed inside the case 10. When a user removes the storage bag 20, first, they pull the control member 35 downwards to move the control member 35 from the first position to the second position. At this time, the inclined surface 350 of the control member 35 acts on the engagement seat 33, and the engagement seat 33 moves in a direction away from the outer housing 34, thereby releasing the fixed state between the engagement seat 33 and the outer housing 34. Next, the user applies force to the second movable member 42 of the second quick-release assembly member 40 to remove the second movable member 42 from the second fixing member 41. The storage bag 20 can be removed from the storage space 11 of the case 10 after the fixing relationship between the first quick-release assembly member 30 and the second quick-release assembly member 40 is released.

[0024] On the other hand, when a user re-secures the storage bag 20 inside the case 10, they only need to bring the first movable member 32 and the first fixed member 31 closer together. Once they reach a certain distance, the magnetic force of the neodymium magnets in the outer housing 34 and the engagement seat 33 causes the first movable member 32 and the first fixed member 31 to be attracted together automatically, thus securing them (see Figure 6). The re-connection method of the second movable member 42 and the second fixed member 41 of the second quick-release assembly member 40 is similar, so a detailed explanation will not be repeated here.

[0025] (Second example) Figure 7 shows a suitcase having a quick-release storage bag structure according to a second embodiment of the present invention. The structure of the second embodiment is similar to that of the first embodiment. However, in this embodiment, both the second fixing member 41 and the second movable member 42 are magnets. When the second movable member 42 is coupled to the second fixing member 41, the two magnets attract each other, forming a fixed state.

[0026] (Third embodiment) Figure 8 is a cross-sectional view showing a suitcase having a quick-release storage bag structure according to a third embodiment of the present invention. The structure of the third embodiment is similar to that of the first and second embodiments. However, in this embodiment, the storage bag 20 is not installed adjacent to the front cover 13, but is installed in the center of the storage space 11 of the case 10. In other words, the present invention is not limited to the storage bag 20 being located inside the case 10. Any structure in which a removable storage bag is installed inside the case 10 does not depart from the scope of application of the present invention.

[0027] Although embodiments of the present invention have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments, and design modifications and the like are also included within the scope of the spirit of the present invention.
