The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0025] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and 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, the above terms should not be construed as limitations on this application.

[0026] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0027] refer to Figures 1 to 5 A preferred embodiment of the externally mounted suitcase according to this application will be described in detail below, wherein the externally mounted suitcase includes a main body 10, a plurality of fixed connectors 20, a telescopic pulling assembly 30, and a plurality of adhesive protective parts 40.

[0028] Specifically, the outer portion of the box body 10 is recessed to form at least two rod grooves 101 and a receiving groove 102. The box body 10 has an internal cavity 103. The two rod grooves 101 and the receiving groove 102 are not in communication with the internal cavity 103. The two rod grooves 101 extend in parallel directions. The receiving groove 102 is formed at one end of the box body 10 as a whole. One end of each of the two rod grooves 101 remains in communication with the receiving groove 102.

[0029] The telescopic pulling assembly 30 includes at least two telescopic units 31, a linkage control unit 32, and a fixing member 33. The two telescopic units 31 are each partially accommodated in one of the two rod slots 101. Each of the two telescopic units 31 has a telescopic end 311. The linkage control unit 32 is configured to be accessible from or away from the accommodating slot 102 and connected to the telescopic ends 311 of the two telescopic units 31, so as to uniformly control the extension and retraction of the telescopic ends 311 of the two telescopic units 31. The fixing member 33 is located in the accommodating slot 102. At least one fixing connector 20 is threadedly connected to the fixing member 33, passing through the inner wall of the housing cavity 103, to fix the fixing member 33 to the inner wall of the accommodating slot 102. One end of each of the two telescopic units 31 is fixed to the inner wall of the accommodating slot 102 by the fixing member 33. At least two of the fixed connectors 20 respectively fix the other ends of the two telescopic units 31 to the inner walls of the two rod slots 101 in such a way that they pass through the inner wall of the inner cavity 103 of the box and are threaded to the other ends of the two telescopic units 31.

[0030] Several adhesive protective elements 40 are disposed within the inner cavity 103 of the housing. Each adhesive protective element 40 is fixed to the inner wall of the inner cavity 103 by covering the surface of the fixing connectors 20, thereby preventing items inside the inner cavity 103 from being scratched by the fixing connectors 20. Simultaneously, the adhesive protective elements 40 prevent the fixing connectors 20 from corroding and contaminating the items inside the inner cavity 103.

[0031] It is worth mentioning that, since the telescopic unit 31 is located outside the inner cavity 103 of the box, it can prevent the telescopic unit 31 from scratching the items inside the inner cavity 103 of the box, and at the same time prevent the items inside the inner cavity 103 from being contaminated due to partial corrosion of the linkage control unit 32.

[0032] As an example, some of the said fixing connectors 20 are implemented including screws.

[0033] It is understood that when the linkage control unit 32 controls the extension ends 311 of the two telescopic units 31 to extend, the linkage control unit 32 will move away from the receiving groove 102, and at the same time, the extension ends 311 of the two telescopic units 31 will pass through the receiving groove 102 respectively. Correspondingly, when the linkage control unit 32 controls the extension ends 311 of the two telescopic units 31 to retract, the linkage control unit 32 will enter the receiving groove 102.

[0034] Further, each of the two telescopic units 31 includes a guide rod and a sliding telescopic rod. The guide rods of the two telescopic units 31 are partially accommodated in the two rod slots 101, and one end of each guide rod extends into the receiving slot 102. One end of each guide rod of the two telescopic units 31 is fixed to the fixing member 33 by passing through it, thereby fixing one end of each guide rod. At least two fixing connectors 20 fix the other ends of each guide rod to the inner walls of the two rod slots 101 by passing through the inner wall of the housing cavity 103 and being threadedly connected to the other ends of each guide rod away from the fixing member 33. That is, the two guide rods are fixed by the combined action of the fixing member 33 and at least two fixing connectors 20. The two sliding telescopic rods are movably disposed on the two guide rods, respectively, in a manner that allows them to slide along the extension direction of the two guide rods. The ends of the two sliding telescopic rods near the fixed member 33 are positioned in the receiving groove 102 such that they can pass through the receiving groove 102, and the portions of the two sliding telescopic rods that can pass through the receiving groove 102 are respectively defined as the telescopic ends 311. The telescopic ends 311 of the two sliding telescopic rods are respectively connected to the linkage control unit 32 such that they can pass through the receiving groove 102.

[0035] Preferably, the telescopic pulling assembly 30 is implemented to include a telescopic pull rod.

[0036] Preferably, the externally mounted suitcase further includes a sidewall protector 50. The sidewall protector 50 is adapted to the inner cavity 103 of the suitcase. The sidewall protector 50 is positioned within the inner cavity 103 of the suitcase in a manner that keeps it covering the inner wall of the inner cavity 103.

[0037] It is understandable that when a user places an item inside the inner cavity 103 of the box, the protective component 50 on the box wall can reduce the impact between the item inside the inner cavity 103 and the inner wall of the inner cavity 103, thereby protecting the item placed inside the inner cavity 103 by the user.

[0038] It is worth mentioning that, due to the installation of several adhesive protective elements 40, the enclosure wall protective element 50 can be prevented from being scratched by several fixing connectors 20, while also preventing the fixing connectors 20 from corroding and contaminating the enclosure wall protective element 50. Furthermore, when the adhesive protective element 40 detaches from the inner wall of the enclosure cavity 103, the enclosure wall protective element 50 prevents the fixing connectors 20 from scratching the items inside the enclosure cavity 103.

[0039] In other words, the adhesive protective components 40 and the box wall protective components 50 can work together to provide protection for the items inside the box cavity 103.

[0040] As an example, the enclosure wall protection 50 is selected from, but not limited to, woven materials of nylon and polyester. The enclosure wall protection 50 is implemented to include an inner lining of the enclosure.

[0041] In this embodiment, all of the adhesive protective elements 40 include felt. The adhesive protective elements 40 are respectively adhered and fixed to the inner wall of the inner cavity 103 of the housing in a manner that covers the surface of the fixing connectors 20.

[0042] In another modified embodiment, all of the adhesive protective elements 40 include hook-and-loop fasteners. The externally mounted suitcase also includes a plurality of loop fasteners corresponding to the adhesive protective elements 40. The loop fasteners are disposed on the suitcase wall protector 50 in a manner that keeps them opposite to the adhesive protective elements 40, so as to fix the position of the suitcase wall protector 50 by mutual attraction between the adhesive protective elements 40 and the loop fasteners.

[0043] As an example, several of the aforementioned circumferential Velcro straps are respectively sewn and fixed to the box wall protective member 50.

[0044] To enable those skilled in the art to understand this application, in at least one embodiment of this application, the example is simply that all of the aforementioned adhesive protective elements 40 are implemented to include felt, and that the aforementioned adhesive protective elements 40 are respectively adhered and fixed to the inner wall of the inner cavity 103 of the box body in a manner that covers the surface of the aforementioned fixed connectors 20.

[0045] Preferably, the outer portion of the box body 10 is recessed to form a connecting groove 104. The connecting groove 104 is located at the ends of the two rod grooves 101 away from the receiving groove 102. The two ends of the connecting groove 104 are respectively connected to the ends of the two rod grooves 101 away from the receiving groove 102. The recess depth of the connecting groove 104 is less than the recess depth of the two rod grooves 101 to ensure that when the guide rods of the two telescopic units 31 are respectively positioned in the two rod grooves 101, the stability of the two guide rods is improved by having their ends abut against the inner walls of the two rod grooves 101.

[0046] Furthermore, the externally mounted luggage compartment also includes an extension member 60. The extension member 60 is adapted to the connecting groove 104, and the extension member 60 is installed within the connecting groove 104 to improve the overall aesthetic appearance of the ends of the two guide rods away from the fixing member 33.

[0047] As an example, in one embodiment, the extension 60 is adhered to the inner wall of the connecting groove 104 by applying adhesive. In another modified embodiment, at least one of the fixing connectors 20 securely mounts the extension 60 to the connecting groove 104 in a manner that allows it to pass through the inner wall of the housing cavity 103 and be threadedly connected to the extension 60.

[0048] Specifically, the main body 10 of the box includes a first box body 11, a second box body 12, and a plurality of connecting units 13. The periphery of the first box body 11 is detachably connected to the periphery of the second box body 12 through one of the connecting units 13, and the first box body 11 and the second box body 12 together enclose the inner cavity 103 of the box. The outer portion of the second box body 12 is recessed to form two rod grooves 101, a receiving groove 102, and a communicating groove 104. The receiving groove 102 is formed at one end of the second box body 12.

[0049] It is understood that the first box 11 and the second box 12 can be separated by the telescopic pulling component 30, thereby opening the inner cavity 103 of the box to retrieve the items inside the inner cavity 103.

[0050] It is understood that the box wall protection component 50 is divided into two parts, and the two parts of the box wall protection component 50 respectively cover the inner wall of the inner cavity 103 of the box formed by the first box body 11 and the second box body 12.

[0051] Preferably, the first box body 11 has at least one side opening 105 that communicates with the inner cavity 103 of the box body. The box body 10 also includes at least one lid body 14 adapted to at least one of the side openings 105. The periphery of the lid body 14 is detachably connected to the outer edge of the side opening 105 by a connecting unit 13, so as to close the side opening 105 by the lid body 14.

[0052] The formation of at least one of the side openings 105 improves the way items can be placed when using the externally mounted suitcase, thus enhancing user convenience.

[0053] The main body 10 of the box also includes at least one lid divider 15. The periphery of the lid divider 15 is detachably connected to the inner edge of the side opening 105 of the box via a connecting unit 13 in a manner that keeps it opposite to the lid body 14, and forms a placement space for placing items between the lid body 14 and the lid divider 15.

[0054] It is understood that, since the cover separator 15 is provided between the inner cavity 103 of the box and the placement space, the items in the placement space are prevented from mixing into the inner cavity 103 of the box, so as to achieve the separation and isolation of the items, and thus facilitate the use and storage of the required items.

[0055] As an example, several of the connection units 13 are implemented to include zippers.

[0056] The main body 10 of the suitcase also includes a plurality of movable parts 16. The plurality of movable parts 16 are respectively disposed on the first suitcase body 11 and the second suitcase body 12, and the plurality of movable parts 16 are all located at the end of the second suitcase body 12 away from the receiving groove 102. The plurality of movable parts 16 are used to reduce the friction between the first suitcase body 11 and the second suitcase body 12 and the ground when the suitcase body is moved by pulling the external pull rod by the telescopic pull assembly 30.

[0057] As an example, several of the said movable parts 16 are implemented to include casters.

[0058] Preferably, the box body 10 further includes at least one lifting member 17. At least one of the lifting members 17 is mounted on the second box body 12. The lifting member 17 is provided with a handle.

[0059] At least one of the fixed connectors 20 is used to install the lifting member 17 onto the second housing 12 in such a way that it passes through the inner wall of the inner cavity 103 of the housing and is threadedly connected to the lifting member 17.

[0060] Preferably, the main body 10 further includes a locking member 18. The locking member 18 is installed on the first box 11 so that when the periphery of the first box 11 and the periphery of the second box 12 are fully connected by the corresponding connecting unit 13, the locking member 18 locks the position of the connecting unit 13 between the first box 11 and the second box 12.

[0061] The locking element 18 is implemented as a combination lock.

[0062] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
