Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and in particular to a carrier, a luggage, and a luggage assembly. Background Technology

[0002] People usually carry suitcases when traveling, but for those traveling with children, they may face the situation of having to pull the suitcase handle while holding the child, which is inconvenient.

[0003] Therefore, in existing technologies, some suitcases are equipped with a rotating, foldable seat structure, allowing children to sit in the unfolded seat, providing great convenience for travelers with young children. However, this seat structure not only increases the weight of the suitcase itself, reducing its portability, but may also reduce the internal volume of the suitcase, affecting the user experience. Furthermore, existing rotating, foldable seat structures can still rotate relative to the suitcase body when unfolded, posing certain safety hazards during use. Utility Model Content

[0004] Therefore, it is necessary to provide a carrier, a suitcase, and a suitcase assembly to address the above issues, in order to improve user experience and enhance safety.

[0005] This utility model first provides a carrier for detachably mounting on a suitcase. The suitcase is provided with a locking assembly and a second connecting group. The second connecting group includes a first connecting member and a third connecting member. The carrier includes a carrier portion; and the first connecting group includes a second connecting member and a fourth connecting member, both disposed on the carrier portion. The second connecting member is used for detachable connection with the first connecting member. The carrier has a first locked state and a first unlocked state. In the first locked state, the fourth connecting member can cooperate with the locking assembly to restrict the detachment of the fourth connecting member from the third connecting member. In the first unlocked state, the fourth connecting member can be detachably connected to the third connecting member.

[0006] The aforementioned carrier can be used in conjunction with a suitcase, connected to the first connector via a second connector and to the third connector via a fourth connector, thus fixing the carrier relative to the suitcase. Simultaneously, the fourth connector engages with a locking component, placing the carrier in a first locked state. The fourth and third connectors are then immovable, preventing accidental detachment and ensuring the stability and reliability of the connection between the carrier and the suitcase, thereby enhancing safety. Alternatively, the carrier can be used independently, controlled in a first unlocked state, where the fourth and third connectors are detachable, allowing separation from the suitcase. This expands the carrier's applicability and improves user experience.

[0007] This utility model also provides a suitcase for detachably loading a carrier. The carrier is provided with a carrier portion and a first connecting group. The first connecting group includes a second connecting member and a fourth connecting member, both disposed on the carrier portion. The suitcase includes: a suitcase body; a second connecting group disposed on the top surface of the suitcase body, the second connecting group including a first connecting member and a third connecting member, the first connecting member being detachably connected to the second connecting member; and a locking assembly disposed on the top surface of the suitcase body. The locking assembly has a second locked state and a second unlocked state. In the second locked state, the locking assembly cooperates with the fourth connecting member to restrict the detachment of the fourth connecting member from the third connecting member. In the second unlocked state, the fourth connecting member can be detachably connected to the third connecting member.

[0008] In the aforementioned suitcase, the suitcase can be used in conjunction with a carrier component, connected via a first connector and a second connector, and a third connector and a fourth connector, thus fixing the carrier component relative to the suitcase. Simultaneously, in the second locked state, the locking component engages with the fourth connector, preventing the third and fourth connectors from being disassembled and preventing accidental detachment of the carrier component and the suitcase. This ensures the stability and reliability of the connection between the carrier component and the suitcase, improving the safety of both components. Alternatively, the suitcase can be used independently. By controlling the locking component in the second unlocked state, the third and fourth connectors can be disassembled, allowing the carrier component to separate from the suitcase. This expands the suitcase's applicability. Furthermore, the detachable connection between the carrier component and the suitcase reduces the suitcase's weight, and the carrier component does not occupy internal space, thus improving portability and enhancing the user experience.

[0009] This utility model also provides a luggage assembly, including: a carrier, comprising a carrier portion and a first connecting group, the first connecting group including a second connecting member and a fourth connecting member both disposed on the carrier portion; and a luggage, comprising a body, a second connecting group and a locking assembly, the second connecting group being disposed on the top surface of the body, the second connecting group including a first connecting member and a third connecting member, the first connecting member and the second connecting member being detachably connected; wherein, the locking assembly has a second locked state and a second unlocked state, in the second locked state, the locking assembly cooperates with the fourth connecting member to restrict the detachment of the fourth connecting member and the third connecting member; in the second unlocked state, the fourth connecting member can be detachably connected to the third connecting member.

[0010] In the aforementioned luggage assembly, when the carrier needs to be used in conjunction with the luggage, the first connector connects to the second connector, and the third and fourth connectors connect to fix the carrier relative to the luggage. Then, the locking control assembly is in a second locking state, and the locking assembly cooperates with the fourth connector to prevent the third and fourth connectors from being disassembled, thus preventing the carrier and luggage from accidentally separating. This ensures the stability and reliability of the connection between the carrier and the luggage, improving the safety of using both the carrier and the luggage. When the carrier or the luggage needs to be used alone, the locking control assembly is in a second unlocking state, and then the third and fourth connectors are disassembled, as are the first and second connectors, separating the carrier from the luggage body. In this way, the luggage body can be used alone when the carrier is not in use, and the carrier can be used alone when the luggage is not in use, improving the user experience.

[0011] In one embodiment, the third connector is a first slot located on the top of the housing, and the fourth connector is a first plug-in protruding from the bottom of the support member, wherein the first plug-in can be inserted into the first slot.

[0012] With this configuration, in the second locking state, the first connector cannot be pulled out of the first slot, and the connection between the third and fourth connectors is simple and easy for users to install and disassemble.

[0017] In one embodiment, the locking assembly further includes a pressing member slidably disposed on the top of the suitcase along the height direction of the suitcase. The pressing member has a first inclined surface, and the locking member has a second inclined surface that slides in cooperation with the first inclined surface. When the pressing member is pressed toward the bottom of the suitcase, the locking member slides out of the lock hole.

[0018] This design allows the user to easily control the locking mechanism by pressing the button.

[0019] In one embodiment, the first connector is a protrusion protruding from the top of the housing, and the second connector is a slot provided on the carrier. The slot has an insertion position and a fixing position that communicate with each other. The protrusion can be inserted from the insertion position and slid to the fixing position to fix the protrusion to the carrier. Alternatively, the first connector is a second slot provided on the top of the housing, and the second connector is a second plug-in protruding from the bottom of the carrier. The second plug-in can be inserted and engaged with the second slot.

[0020] With this design, the connection between the first and second connectors is simple and easy for users to assemble and disassemble.

[0045] People typically carry suitcases when traveling, but for those traveling with children, this can be inconvenient, requiring them to pull the suitcase handle while holding the child. Therefore, some existing suitcases incorporate a rotating, foldable seat structure, allowing children to sit in the unfolded seat, greatly facilitating travel for families with young children. However, this seat structure not only increases the weight of the suitcase, reducing its portability, but may also reduce internal volume, impacting the user experience. Furthermore, existing rotating seat structures can still rotate relative to the suitcase body when unfolded, posing a safety hazard during use.

[0046] To solve the above problems, such as Figures 1 to 11 As shown, this utility model provides a carrier, a suitcase, and a suitcase assembly to improve user experience and enhance safety.

[0047] like Figure 1As shown, the luggage assembly includes a carrier and a luggage compartment. The carrier is detachably mounted on the luggage compartment, and the luggage compartment is detachably loaded with the carrier. Specifically, the carrier includes a carrier portion 5 and a first connecting group 1. The first connecting group 1 includes a second connecting member 11 and a fourth connecting member 12, both disposed on the carrier portion 5. The luggage compartment includes a compartment body 4, a second connecting group 2, and a locking assembly 3. The second connecting group 2 is disposed on the top surface of the compartment body 4 and includes a first connecting member 21 and a third connecting member 22. The first connecting member 21 and the second connecting member 11 are detachably connected. The carrier has a first locked state and a first unlocked state, and the locking assembly 3 has a second locked state and a second unlocked state. In the second locked state, i.e., the carrier is in the first locked state, the locking assembly 3 cooperates with the fourth connecting member 12 to restrict the detachment of the fourth connecting member 12 and the third connecting member 22. In the second unlocked state, i.e., the carrier is in the first unlocked state, the fourth connecting member 12 can be detachably connected to the third connecting member 22.

[0048] The support component 5 can be a child seat, adult seat, baby cradle, storage basket, shelf, table, or other structure used to support people or objects. Different functions of the support component 5 can be selected according to user needs and usage scenarios; this embodiment of the invention does not impose specific limitations. For ease of description, the following explanation uses a seat as an example, including either a child seat or an adult seat.

[0049] like Figure 1 As shown in the Cartesian coordinate system, when the suitcase is in an upright position, the ±X-axis is defined as the length direction of the suitcase, the ±Y-axis as the width direction, and the ±Z-axis as the height direction. The +Z-axis is the top of the suitcase, and the -Z-axis is the bottom. It should be noted that the length, width, and height dimensions of the suitcase can be adjusted as needed, and the length can be less than, equal to, or greater than the width.

[0050] In the luggage assembly provided in this embodiment of the utility model, when the carrier needs to be used in conjunction with the luggage, the first connector 21 is connected to the second connector 11, and the third connector 22 and the fourth connector 12 are connected to fix the carrier relative to the luggage. Then, the locking assembly 3 is controlled to be in the second locking state, that is, the carrier is in the first locking state. The locking assembly 3 cooperates with the fourth connector 12, so that the third connector 22 and the fourth connector 12 cannot be disassembled, preventing the carrier and the luggage from accidentally separating. This ensures the stability and reliability of the connection between the carrier and the luggage, and improves the safety of using the carrier and the luggage. When the carrier or the luggage needs to be used alone, the locking assembly 3 is controlled to be in the second unlocking state, that is, the carrier is in the first unlocking state. Then, the third connector 22 and the fourth connector 12 are disassembled, and the first connector 21 and the second connector 11 are disassembled, so that the carrier is separated from the luggage. In this way, the suitcase can be used independently without the support frame, expanding its applicability, reducing its weight, and improving portability and user experience by not taking up internal space. Furthermore, the support frame can be used independently of the seat in various locations such as high-speed trains, airplanes, and outdoors, further expanding its applicability.

[0051] like Figures 1 to 3 As shown, in one embodiment, the first connector 21 and the third connector 22 are arranged at intervals along the width direction of the suitcase. There are at least two first connectors 21, each arranged at intervals along the length direction of the suitcase. There are also at least two third connectors 22, each arranged at intervals along the length direction of the suitcase. The number of second connectors 11 is the same as the number of first connectors 21, and they are arranged in a one-to-one correspondence with the first connectors 21. The number of fourth connectors 12 is the same as the number of third connectors 22, and they are arranged in a one-to-one correspondence with the third connectors 22. In the illustrated embodiment, the number of each of the first connector 21, third connector 22, second connector 11, and fourth connector 12 is two, forming a four-point fixation. This further improves the stability and reliability of the connection between the load-bearing component and the suitcase, preventing the load-bearing component from moving or tipping over relative to the suitcase. It also avoids the difficulty of assembly caused by an excessive number of first connectors 21, third connectors 22, second connectors 11, and fourth connectors 12.

[0052] Of course, in other embodiments, the first connector 21 and the third connector 22 may be arranged at intervals along the length of the suitcase, the first connector 21 may be arranged at intervals along the width of the suitcase, and the third connector 22 may be arranged at intervals along the width of the suitcase. Furthermore, the number of the first connector 21, the third connector 22, the second connector 11, and the fourth connector 12 may be one, three, four, or more, as long as the stability and reliability of the connection between the load-bearing component and the suitcase can be guaranteed. This embodiment of the present invention does not impose specific limitations here.

[0053] like Figure 3 As shown, in one embodiment, the third connector 22 is a first slot 221 located on the top of the housing 4, and the fourth connector 12 is a first insert 121 protruding from the bottom of the seat. The first insert 121 can be inserted into the first slot 221. It should be noted that when there are at least two third connectors 22, each first slot 221 can be independently provided or interconnected. In this way, the connection method between the third connector 22 and the fourth connector 12 is simple and convenient for users to disassemble and assemble. When the locking assembly 3 is in the locked state, the first insert 121 cannot be pulled out of the first slot 221, so as to ensure the stability and reliability of the insertion and engagement between the first insert 121 and the first slot 221.

[0054] Of course, in other embodiments, the fourth connector 12 can be a first slot 221 located at the bottom of the seat, and the third connector 22 can be a first plug-in 121 protruding from the top of the housing 4, with the first plug-in 121 able to be inserted into the first slot 221. Alternatively, the third connector 22 and the fourth connector 12 can be detachably connected by other engagement methods such as snap-fit.

[0055] like Figures 3 to 5 As shown, in one embodiment, the first connector 121 has a locking hole 1211, and the locking assembly 3 includes a locking member 31. Along a direction perpendicular to the height of the suitcase, i.e., on a plane parallel to XOY, the locking member 31 is slidably disposed on the top of the suitcase body 4 and can be inserted into or removed from the locking hole 1211 to switch between a second locked state and a second unlocked state. When the locking member 31 is inserted into the locking hole 1211, it restricts the movement of the first connector 121 along the height direction of the suitcase, thereby preventing the first connector 121 from being pulled out of the first slot 221. Thus, the locking assembly 3 has a simple structure, facilitating user control of the locking member 31 switching between the second locked state and the second unlocked state.

[0056] like Figures 6 to 7As shown, the locking assembly 3 also includes an elastic element 32 disposed between the locking member 31 and the housing 4. At least when the locking member 31 exits the lock hole 1211, the elastic element 32 is compressed and can apply a force to the locking member 31, causing it to slide towards the lock hole 1211. When the user controls the locking member 31 to slide away from the first connector 121, the elastic element 32 is compressed. After the user releases the locking member 31, the locking member 31 can automatically slide towards the first connector 121 under the elastic force of the elastic element 32. This facilitates user operation and improves the stability and reliability of the insertion and engagement between the locking member 31 and the lock hole 1211, preventing the locking member 31 from accidentally sliding away from the first connector 121 and causing the locking assembly 3 to fail. The elastic element 32 can be a spring, silicone rubber, or other elastic component; no specific limitations are imposed on this invention.

[0057] like Figure 5 As shown, the locking assembly 3 also includes a pressing member 33, which is slidably disposed on the top of the suitcase 4 along the height direction of the suitcase. The pressing member 33 has a first inclined surface 331, and the locking member 31 has a second inclined surface 311 that slides in cooperation with the first inclined surface 331. When the pressing member 33 is pressed towards the bottom of the suitcase 4, the locking member 31 slides out of the lock hole 1211. When it is necessary to control the locking assembly 3 to be in the unlocked state, the user can press the pressing member 33 in the -Z axis direction. The first inclined surface 331 of the pressing member 33 slides in cooperation with the second inclined surface 311 of the locking member 31, so that the locking member 31 slides away from the first plug 121. The elastic member 32 is compressed. After the user releases the pressing member 33, the locking member 31 can automatically slide towards the first plug 121 under the elastic force of the elastic member 32. At the same time, the locking member 31 can push the pressing member 33 to slide back in the +Z axis direction, thereby further facilitating user operation. It should be noted that the locking component 3 can be housed within the case 4 or other structure of the suitcase, with at least a portion of the pressing component 33 exposed so that the user can press the pressing component 33 through the exposed portion.

[0058] Furthermore, at least one of the top surface of the locking member 31 or the bottom surface of the first connector 121 is provided with a third inclined surface 312. When the first connector 121 is inserted into the first slot 221, the first connector 121 and the locking member 31 can cooperate through the third inclined surface 312, so that the locking member 31 slides toward the side away from the first connector 121. Therefore, when installing the carrier, the user does not need to control the locking member 31 to slide toward the side away from the first connector 121, which further facilitates the user's operation.

[0059] In the illustrated embodiment, the suitcase also includes a handle 7 disposed on the top of the suitcase body 4. Along the width direction of the suitcase, both the third connector 22 and the handle 7 are disposed on the side of the suitcase body 4 near the -Y axis direction, and the opening of the lock hole 1211 faces the +Y axis direction. The handle 7 has a receiving cavity, and the locking member 31 is slidably disposed within the receiving cavity along the ±Y axis direction, extending out of the receiving cavity and inserting into the lock hole 1211. The pressing member 33 is slidably disposed within the receiving cavity along the ±Z axis direction, with a portion of the pressing member 33 protruding from the receiving cavity to allow the user to press the pressing member 33 through the exposed portion. Furthermore, one pressing member 33 can simultaneously engage with two locking members 31.

[0060] Of course, the user can also directly control the locking member 31 to slide towards or away from the first connector 121, so that the locking member 31 switches between the second locked state and the second unlocked state.

[0061] like Figures 9 to 11 As shown, in another embodiment, the inner wall of the lock hole 1211 is provided with a first engaging portion 1212. The locking member 31 includes a spring piece 313 and a second engaging portion 314 disposed on the spring piece 313. The second engaging portion 314 can engage with the first engaging portion 1212. When the user controls the locking member 31 to slide closer to the first insert 121, the spring piece 313 can deform after being pushed by the first insert 121, allowing the locking member 31 to be inserted into the lock hole 1211. When the locking member 31 is inserted into place, the spring piece 313 can automatically reset under its own elastic force, so that the second engaging portion 314 engages with the first engaging portion 1212. The first engaging portion 1212 and the second engaging portion 314 can improve the stability and reliability of the engagement between the locking member 31 and the lock hole 1211, prevent the locking member 31 from accidentally sliding away from the first insert 121, which would cause the locking assembly 3 to fail, and make the operation simple and convenient for the user. When it is necessary to disassemble the carrier, a large force is applied to the locking member 31 in a direction away from the first plug member 121, so that the spring piece 313 can deform, the second locking part 314 separates from the first locking part 1212, and the locking member 31 can be removed from the lock hole 1211.

[0062] In the illustrated embodiment, the suitcase also includes a handle 7 disposed on the top of the suitcase body 4. Along the width direction of the suitcase, the third connector 22 and the handle 7 are both disposed on the side of the suitcase body 4 near the -Y axis direction. The handle 7 extends along the ±X axis direction, and the opening of the lock hole 1211 faces the ±X axis direction. The locking assembly 3 also includes a sliding member 34 connected to the locking member 31. The sliding member 34 is slidably disposed on the handle 7 along the ±X axis, and the user can control the locking member 31 to slide along the ±X axis through the sliding member 34. The number of locking members 31 can be one, and both ends of the locking member 31 can be provided with a spring piece 313 and a second locking part 314, so that the user can control the locking member 31 to cooperate with any of the first plug-in members 121; or, the number of locking members 31 can be two, and the two locking members 31 can cooperate with one of the first plug-in members 121 respectively.

[0063] like Figures 1 to 3 As shown, in one embodiment, the first connector 21 is a protrusion 211 protruding from the top of the housing 4, and the second connector 11 is a slot 111 provided in the seat. The slot 111 has an insertion position 1111 and a fixing position 1112 that are in communication with each other. The protrusion 211 can be inserted into the insertion position 1111 and slid to the fixing position 1112 to fix the protrusion 211 to the seat. In this way, the connection method between the first connector 21 and the second connector 11 is simple and convenient for users to disassemble and assemble.

[0064] Specifically, the cross-sectional dimension of the insertion position 1111 is larger than that of the fixed position 1112. The protrusion 211 includes a small-diameter section 2112 protruding from the top of the box body 4 and a large-diameter section 2111 located on top of the small-diameter section 2112. The cross-sectional dimension of the small-diameter section 2112 is less than or equal to the cross-sectional dimensions of the insertion position 1111 and the fixed position 1112. The cross-sectional dimension of the large-diameter section 2111 is less than or equal to the cross-sectional dimension of the insertion position 1111 and larger than that of the fixed position 1112. When installing the carrier, first align the protrusion 211 with the insertion position 1111, then insert the protrusion 211 from the insertion position 1111 and slide it to the fixed position 1112. The large-diameter section 2111 can prevent the protrusion 211 from directly dislodging from the slot 111 at the fixed position 1112, thereby preventing the carrier from separating directly from the luggage in the +Z axis direction. When it is necessary to disassemble the carrier, first slide the protrusion 211 from the fixed position 1112 to the insertion position 1111, and then control the protrusion 211 to disengage from the insertion position 1111.

[0065] It should be noted that when the third connector 22 and the fourth connector 12 are connected by the first plug 121 and the first slot 221, the protrusion 211 engages with the fixed position 1112. The protrusion 211 needs a certain amount of room for movement along the ±Z axis to ensure that the first plug 121 can be smoothly inserted into or removed from the first slot 221.

[0066] Of course, in other embodiments, the first connector 21 is a second slot (not shown) located on the top of the housing 4, and the second connector 11 is a second plug-in (not shown) protruding from the bottom of the seat, which can be inserted into the second slot. Alternatively, the second connector 11 can be a second slot located at the bottom of the seat, and the first connector 21 can be a second plug-in protruding from the top of the housing 4, which can be inserted into the second slot. It should be noted that when there are at least two second slots, each second slot can be independently provided or interconnected.

[0067] Furthermore, in the locked state, the locking component 3 can also be used to restrict the disassembly of the first connector 21 and the second connector 11. Alternatively, there can be two locking components 3, in which the two locking components 3 are used to restrict the disassembly of the first connector 21 and the second connector 11 and to restrict the disassembly of the third connector 22 and the fourth connector 12, respectively, in the locked state.

[0068] like Figure 1 As shown, the suitcase also includes a pull rod assembly 6, which is located on one side wall of the suitcase body 4 in the width direction. The support part 5 is a seat, which faces the pull rod assembly 6. The seat includes a seat part 51 and a backrest part 52. The seat facing the pull rod assembly 6 means that the backrest part 52 is located at the end of the seat part 51 away from the pull rod assembly 6. Users can pull the suitcase using the pull rod assembly 6. When the pull rod assembly 6 is extended, it can also protect children sitting in the seat, reducing the risk of children falling off the seat.

[0069] like Figures 6 to 7 As shown, the seat 51 can be rotatably connected to the backrest 52. When the support member is not needed, the backrest 52 can be rotated relative to the seat 51 to a folded storage state, reducing the overall volume of the support member for easier storage. Furthermore, at least one of the seat 51 and the backrest 52 is provided with a stop 511, which can limit the rotation angle of the backrest 52 relative to the seat 51, improving the stability of the support member in the unfolded use state.

[0070] like Figures 1 to 2 As shown, the pull rod assembly 6 includes a telescopic rod (not shown), a first handle 61, and a second handle 62. The telescopic rod extends along the height of the suitcase, the first handle 61 is located at the top of the telescopic rod, and the second handle 62 extends outward from both ends of the first handle 61 along the length of the suitcase. When a child is sitting in the seat, an adult can pull the suitcase using the first handle 61, while the child can grip the second handle 62 with both hands, thereby further improving the safety of using the suitcase.

[0071] The telescopic rod extends along the ±Z axis and can extend and retract in the ±Z direction. A button on the first handle 61 controls the extension and retraction of the telescopic rod; the user can control the extension and retraction by pressing the button. The first handle 61 and the second handle 62 can be adjusted in height by the extension and retraction of the telescopic rod, allowing users of different heights to use it in different environments. Furthermore, there can be two telescopic rods, spaced apart along the ±X axis, each connected to one end of the first handle 61. Alternatively, there can be only one telescopic rod, connected to the middle of the first handle 61, as long as the overall strength of the pull rod assembly 6 and the stability of the first handle 61 and the second handle 62 when moving up and down along the ±Z axis are guaranteed. This embodiment of the invention does not impose specific limitations here.

[0072] Furthermore, the second handle 62 is provided with a hook 621, which allows the user to hang the bag's strap or handle on the hook 621, so that the user does not need to carry the bag while pulling the first handle 61 of the suitcase.

[0073] like Figure 3 and Figure 8 As shown, the suitcase also includes a handle 7 located on the top of the suitcase body 4, and a pull rod assembly 6 and a handle 7 respectively located on the two side walls of the suitcase body 4 in the width direction. When the suitcase is heavy, the user can simultaneously grasp the pull rod assembly 6 and the handle 7 located on both sides of the suitcase body 4 to facilitate the user's carrying of the suitcase and improve the safety of use.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
