[0002] The present invention relates to the technical field of suitcases, in particular to trolleys and suitcases. [Background technology]

[0003] When people go out, they have to pull a suitcase trolley while carrying a drink bottle or a coffee cup, which can make mobility difficult.

[0004] Some conventional suitcases have cup holders on the side of the suitcase or the side of the trolley for placing bottles and cups. However, when walking with the suitcase, the foot is likely to hit the cup holder, making it difficult to use. Furthermore, due to the height restriction of the suitcase, if the bottle or cup is placed in the cup holder on the side of the suitcase, the user must squat down to take out the bottle or cup, and this is easily forgotten.

[0005] According to various embodiments of the present invention, a trolley and a suitcase are provided.

[0006] The trolley includes a connecting rod assembly, a handle assembly, and a support part. The handle assembly is mounted on the connecting rod assembly, the handle assembly including a first handle and a second handle spaced apart along a first preset direction. The support part is mounted on the handle assembly and recessed on a side facing the connecting rod assembly, and the support part, the first handle, and the second handle form a storage space.

[0007] The handle assembly includes connecting pieces having opposite ends connected to the first handle and the second handle, the number of the connecting pieces being at least two, and the at least two connecting pieces being spaced apart along a second preset direction.

[0008] The support part comprises a U-shaped support part and two connection parts fixed to each other, and ends of the two connection parts remote from the support part are connected to the two connection parts, respectively.

[0009] A distance a between the first handle and the second handle satisfies 50 mm≦a≦80 mm, a distance b between the two connecting parts satisfies 100 mm≦b≦200 mm, and a depth c of the storage space satisfies 10 mm≦c≦60 mm.

[0010] The support portion is provided with a first groove for placing an electronic device thereon.

[0011] A width d of the first groove along the first preset direction satisfies 10 mm≦d≦15 mm, a length e of the first groove along the second preset direction satisfies 60 mm≦e≦190 mm, and a depth f of the first groove satisfies 5 mm≦f≦25 mm.

[0012] Each of the connection parts is provided with a second groove for placing an electronic device in the same position, and both ends of the second groove extend to edges of the connection parts along the second preset direction.

[0013] A width g of the second groove along the first preset direction satisfies 10 mm≦g≦15 mm, and a depth h of the second groove satisfies 12 mm≦h≦38 mm.

[0014] An inner wall surface of the second groove adjacent to the second handle is provided as an inclined surface.

[0015] The inclination angle θ of the inclined surface satisfies 0°≦θ≦25°.

[0016] A side surface of the second handle facing the storage space is provided with a plurality of recesses.

[0017] The trolley further includes a hook disposed on the handle assembly or on the support part.

[0018] The connecting rod assembly includes a telescopic rod, and the handle assembly is mounted on a telescopic end of the telescopic rod.

[0019] The suitcase includes a case body and the trolley, and the trolley is disposed in the case body.

[0020] The case body is provided with an accommodating groove for accommodating the handle assembly and the support part, and the size of the accommodating groove is equal to the size of the handle assembly and the support part, or the size of the accommodating groove is larger than the size of the handle assembly and the support part.

[0021] The receiving groove can prevent the handle assembly and the supporting parts from protruding from the case body and increasing the overall volume of the suitcase. The suitcase has a large capacity without changing its overall size. In addition, when the size of the receiving groove is larger than that of the handle assembly, there is a certain distance between the second handle and the inner wall of the receiving groove, making it easier for the user to hold the second handle.

The term "and / or" used in the description of the present invention includes any combination or any combination of one or more of the associated listed items.

[0030] When people go out, they need to pull a suitcase trolley while holding a drink bottle or coffee cup, which can make it difficult to move. Conventional suitcases are provided with cup holders on the side of the suitcase or the side of the trolley, and users can place bottles or cups in the cup holder when waiting for a bus or walking. However, when a user walks with a suitcase, their feet are likely to hit the cup holder, making it difficult to use, and due to the height limit of the suitcase, when placing a bottle or cup on the side of the suitcase, the user must squat down to take out the bottle or cup, which is easily forgotten.

[0031] In order to solve the above problems, the present invention provides a trolley 100, as shown in Figures 1 to 4. The trolley 100 is convenient for users to place bottles and cups on, and is unlikely to forget bottles or cups, and is unlikely to cause users' feet to hit the cup holder, making it convenient to use.

[0032] As shown in Figures 1 to 4, the first preset direction is defined as ±X-axis direction, the second preset direction is defined as ±Y-axis direction, and the extension direction of the connecting rod assembly 1 is defined as ±Z-axis direction.

[0033] 1, the trolley 100 includes a connecting rod assembly 1, a handle assembly 2, and a support part 3. The handle assembly 2 is provided on the connecting rod assembly 1, and includes a first handle 21 and a second handle 22 spaced apart along the ±X-axis directions. The support part 3 is provided on the handle assembly 2 and recessed on the side facing the connecting rod assembly 1, i.e., the support part 3 is recessed toward the -Z-axis direction, and the support part 3, the first handle 21, and the second handle 22 form a storage space 33 in which other items such as bottles and cups can be placed.

[0034] As described above, in the conventional suitcase, the cup holder is arranged on the side of the suitcase or the side of the trolley, so that when a user walks with the suitcase, the user's feet are likely to hit the cup holder, which is inconvenient to use. In the trolley 100 provided in this embodiment, the user can place other items such as a bottle or cup in the storage space 33 formed by the first handle 21, the second handle 22, and the support part 3. The support part 3 is used to support the bottle or cup, and the first handle 21 and the second handle 22 are used to limit the position of the bottle or cup to prevent the bottle or cup from falling. This eliminates the need to hold the bottle or cup by hand. Since the bottle or cup is arranged between the first handle 21 and the second handle 22, the user's feet will not hit the bottle or cup when walking while pulling the suitcase 200, making it easy to use. In addition, by placing the bottle or cup in the storage space 33 at a higher position than placing it on the side of the suitcase 200, it becomes easier for the user to take it out, and it also functions as a reminder to not forget the bottle or cup.

[0035] At the same time, the trolley 100 provided by this embodiment uses the first handle 21 and the second handle 22 to form the storage space 33, and does not require any additional structure for the connecting rod assembly 1. This prevents the connecting rod assembly 1 of the trolley 100 from taking up excessive space in the suitcase 200 or other device, and increases the internal capacity of the suitcase 200 or other device without changing its overall volume.

[0036] As shown in FIG. 1 and FIG. 2, in the illustrated embodiment, the connecting rod assembly 1 includes a connecting rod 12 and two telescopic rods 11 respectively connected to both ends of the connecting rod 12, and the end of the telescopic rod 11 far from the connecting rod 12 is a telescopic end 111, which can be extended and retracted along the ±Z axis direction relative to the connecting rod 12, and the telescopic ends 111 of the two telescopic rods 11 are respectively connected to both ends of the first handle 21. The first handle 21 is provided with a button 211 for controlling the extension and retraction of the telescopic rod 11, and a user can press the button 211 to control the extension and retraction of the telescopic rod 11 through the first handle 21. The handle assembly 2 and the support part 3 can also adjust the height by the extension and retraction of the telescopic rod 11. When a user walks with a device such as a suitcase 200 through the first handle 21, the telescopic rod 11 is pulled up, and the bottle or cup placed in the storage space 33 is also pulled up together with the handle assembly 2 and the support part 3, making it easier for the user to take it out. When the telescopic rod 11 is in a contracted state, a user can lift an apparatus such as a suitcase 200 via the second handle 22, and since the second handle 22 is closer to the middle position of the apparatus such as the suitcase 200 than the first handle 21, it is possible to ensure that the balance of the apparatus such as the suitcase 200 is maintained when the apparatus such as the suitcase 200 is lifted via the second handle 22.

[0037] In other embodiments, the telescopic ends 111 of the two telescopic rods 11 may be connected to the first handle 21 and the second handle 22, respectively, or the two telescopic rods 11 may be provided separately without being connected via the connecting rod 12. Of course, in other embodiments, the connecting rod assembly 1 may have only one telescopic rod 11, and the telescopic end 111 of the telescopic rod 11 may be connected to the middle position of the first handle 21 or the second handle 22, as long as the strength of the trolley 100 is ensured.

[0038] As shown in FIG. 1, the handle assembly 2 includes a connecting part 23, both ends of which are connected to the first handle 21 and the second handle 22, respectively. The number of the connecting parts 23 is at least two, and the at least two connecting parts 23 are spaced apart along the ±Y axis direction. In the illustrated embodiment, the number of the connecting parts 23 is two, two connecting parts are provided at both ends of the first handle 21, and two connecting parts 23 are provided at both ends of the second handle 22. The first handle 21, the second handle 22 and the two connecting parts 23 are surrounded to form a rectangular structure. The first handle 21 and the second handle 22 are used to limit the position of the bottle or cup placed in the storage space 33 in the ±X axis direction. The connecting part 23 is used to limit the position of the bottle or cup placed in the storage space 33 in the ±Y axis direction, so as to prevent the bottle or cup from tipping over or falling. Of course, in other embodiments, the number of the connecting parts 23 may be three, four or more, and one or more bottles or cups may be placed between two adjacent connecting parts 23, as long as the position of the bottle or cup can be limited. The present embodiment is not particularly limited.

[0039] Here, the connection between the connecting part 23 and the first handle 21, and between the connecting part 23 and the second handle 22 can be made through an arc portion, which can avoid stress concentration and improve the strength of the handle assembly 2. This allows the trolley 100 to meet the strength requirements of devices such as the suitcase 200.

[0040] As shown in FIG. 2, in one embodiment, the support part 3 includes a U-shaped support part 31 and two connecting parts 32 fixed to each other. The support part 31 can extend along the ±Y axis direction, and the ends of the two connecting parts 32 far from the support part 31 are respectively connected to the two connecting parts 23. The support part 31 is used to support articles such as bottles and cups placed in the storage space 33. The connecting part 32 is used to connect the support part 31 to the handle assembly 2, which can further restrict the position of the bottle or cup and prevent the bottle or cup from falling. Here, there is one support part 3, and the support part 3 is disposed at the middle position of the connecting part 23, so that a large space is formed between the support part 3 and the first handle 21 and between the support part 3 and the second handle 22, which ensures that the bottle or cup placed in the storage space 33 will not fall and does not affect the user's grip of the first handle 21 and the second handle 22. Of course, the number of support parts 3 may be multiple, and the multiple support parts 3 may be arranged at intervals along the ±X-axis directions, as long as it does not affect the user's grip of the first handle 21 and the second handle 22. In this embodiment, there is no particular limitation.

[0041] In another embodiment, the support part 31 may extend along the ±X-axis direction, and the ends of the two connecting parts 32 far from the support part 31 are connected to the first handle 21 and the second handle 22, respectively. The number of the support parts 3 may be one or more than one, and the multiple support parts 3 are arranged at intervals along the ±Y-axis direction. Alternatively, the multiple support parts 3 may be arranged crosswise. That is, some of the support parts 31 extend along the ±X-axis direction, and other support parts 31 extend along the ±Y-axis direction, and the multiple support parts 31 are connected in a cross shape. The connecting parts 32 corresponding to the support parts 31 extending in the ±X-axis direction are connected to the first handle 21 and the second handle 22, and the connecting parts 32 corresponding to the support parts 31 extending in the ±Y-axis direction are connected to the connecting parts 23, so long as the bottles and cups placed in the storage space 33 do not fall and the user's grip of the first handle 21 and the second handle 22 is not affected. This embodiment is not particularly limited.

[0042] As shown in FIG. 3 and FIG. 4, the distance a between the first handle 21 and the second handle 22 satisfies 50 mm≦a≦80 mm. In this way, the user can easily hold the first handle 21 and the second handle 22, and bottles or cups of different diameters can be placed in the storage space 33, and after being placed, large shaking is unlikely to occur in the storage space 33. The distance b between the two connecting parts 23 satisfies 100 mm≦b≦200 mm. In this way, when the bottles or cups are placed vertically, two or more bottles or cups can be placed side by side in the storage space 33, or low-height bottles, pop cans, etc. can be placed horizontally, and the range of application is wide. The depth c of the storage space 33 satisfies 10 mm≦c≦60 mm. The depth c of the storage space 33 is the size of the storage space 33 along the ±Z axis direction. This ensures stability when the bottles or cups are placed in the storage space 33, and prevents the bottles or cups from falling. At the same time, by limiting the size of the storage space 33 in all directions, it is possible to prevent the trolley 100 from becoming too large and occupying too much space inside a device such as a suitcase 200.

[0043] As shown in FIG. 2, the support portion 31 is provided with a first groove 311 for placing an electronic device 34 such as a mobile phone or tablet computer. When placed vertically, the electronic device 34 such as a mobile phone or tablet computer has a relatively high center of gravity and is therefore prone to tipping over. Therefore, when it is necessary to use the electronic device 34 such as a mobile phone or tablet computer in a vertical position, the electronic device 34 such as a mobile phone or tablet computer can be placed in the first groove 311, and since the storage space 33 has a certain depth, when the electronic device 34 such as a mobile phone or tablet computer is placed in the first groove 311, it will lean against the first handle 21 or the second handle 22. This ensures the safety and stability of the electronic device 34 such as a mobile phone or tablet computer, and prevents the electronic device 34 from tipping over or falling.

[0044] As shown in FIG. 3 and FIG. 4, the width d of the first groove 311 along the ±X axis satisfies 10 mm≦d≦15 mm, and the length e of the first groove 311 along the ±Y axis satisfies 60 mm≦e≦190 mm. In this way, electronic devices 34 such as mobile phones and tablet computers with different widths and thicknesses, or electronic devices 34 with protective shells, can be reliably placed in the first groove 311, and the range of applications is wide. The depth f of the first groove 311 is the size of the first groove 311 along the ±Z axis direction, and satisfies 5 mm≦f≦25 mm. This ensures the stability of the electronic device 34 such as a mobile phone or tablet computer when placed in the first groove 311, and prevents the electronic device 34 from slipping. At the same time, by limiting the size of the first groove 311 in all directions, it is also possible to prevent the size of the support part 31 from being too large, which would cause the overall size of the trolley 100 to be excessively large or affect the user's ability to grip the first handle 21 and the second handle 22.

[0045] As shown in FIG. 2 and FIG. 6, each connecting part 23 is provided with a second groove 231 for placing the electronic device 34 in the same position, and both ends of the second groove 231 extend to the edge of the connecting part 23 along a second preset direction. When the electronic device 34, such as a mobile phone or a tablet computer, needs to be used in a landscape orientation, the electronic device 34 can be placed in the second groove 231. Since both ends of the second groove 231 extend to the edge of the connecting part 23, the second groove 231 does not limit the size of the electronic device 34 along the ±Y axis direction when the electronic device 34 is used in a landscape orientation. In addition, the plurality of connecting parts 23 improves the stability of the electronic device 34 placed in the second groove 231, and can prevent the electronic device 34 from tipping over or falling.

[0046] As shown in Figures 3 and 4, the width g of the second groove 231 along the first preset direction satisfies 10mm ≦ g ≦ 15mm. In this way, electronic devices 34 such as mobile phones and tablet computers with different thicknesses or electronic devices 34 with protective shells can be reliably placed in the second groove 231, and it can be ensured that they are not easily slippery in the second groove 231. The depth h of the second groove 231 satisfies 12mm ≦ h ≦ 38mm. This ensures the stability of the electronic devices 34 such as mobile phones and tablet computers when they are placed in the second groove 231, and prevents the electronic devices 34 from tipping over or falling. At the same time, by limiting the size of the second groove 231 in all directions, it is also possible to prevent the overall size of the trolley 100 from becoming excessively large due to the excessive size of the connecting part 23 and the second handle 22.

[0047] 3, in order to ensure that a user can lift an apparatus such as a suitcase 200 through the second handle 22, the second handle 22 needs to be flush with the first handle 21 or slightly higher than the first handle 21, and there is a certain amount of clearance between the second handle 22 and an apparatus such as a suitcase 200 so that a user can grip the second handle 22. When the first handle 21 and the second handle 22 are flush with each other, the depth of the second groove 231 is the size of the inner wall surfaces on both sides of the second groove 231 along the ±Z axis direction, and when the second handle 22 is slightly higher than the first handle 21, the depth of the second groove 231 is the size of the inner wall surface close to the second handle 22 along the Z axis direction.

[0048] 2 and 3, an inner wall surface of the second groove 231 adjacent to the second handle 22 is provided as an inclined surface 2311. In this manner, when electronic devices 34 such as mobile phones and tablet computers are placed in the second groove 231, the electronic devices 34 lean against the inclined surface 2311, ensuring the stability of the electronic devices 34 and improving the comfort of the user. Here, the inclination angle θ of the inclined surface 2311 satisfies 0°≦θ≦25°, and when the electronic device 34 such as a mobile phone or tablet computer is inclined within this angle range, the user can obtain the best viewing effect and be more comfortable when viewing the screen of the electronic device 34 such as a mobile phone or tablet computer.

[0049] As shown in FIG. 2 and FIG. 4, since a user usually needs to hold the second handle 22 to lift an apparatus such as the suitcase 200, and the apparatus such as the suitcase 200 is usually heavy, a plurality of recesses 221 are provided on the side of the second handle 22 facing the storage space 33. The recesses 221 can accommodate the shape of the user's hand, making it more comfortable for the user to hold the second handle 22. In addition, when the bottle or cup is placed vertically, the recesses 221 can also limit the position of the bottle or cup, preventing the bottle or cup from slipping in the ±Y-axis direction. Of course, the first handle 21 can also be provided with a plurality of recesses 221 so that the user can hold the first handle 21 more comfortably.

[0050] As shown in FIG. 2, when going out, if a user needs to carry a bag while pulling the trolley 100 of the suitcase 200, the bag may easily collide with the suitcase 200 or the user's feet, which may make the user's travel inconvenient. Therefore, the trolley 100 further includes a hook 4 arranged on the handle assembly 2 or the support part 3. The hook 4 can be used to hang other items such as a bag, and the item hung on the hook 4 is less likely to collide with the suitcase 200 or the user's feet. This makes the user's travel even easier. Here, the number of hooks 4 may be one or more than two, and the hooks 4 may be provided on both the handle assembly 2 and the support part 3 as long as they do not interfere with other structures. In this embodiment, there is no particular limitation.

[0051] As shown in FIG. 5, the present invention further provides a suitcase 200. The suitcase 200 includes a case body 5 and the above-mentioned trolley 100 disposed in the case body 5. A mounting groove 52 is provided on the side of the case body 5, which is shaped to match the shape of the connecting rod assembly 1. The connecting rod assembly 1 is embedded in the mounting groove 52, which prevents the connecting rod assembly 1 from protruding from the case body 5 and thus prevents the overall size of the suitcase 200 from becoming large. Since the first handle 21 is connected to the connecting rod assembly 1, the user can push the case body 5 through the first handle 21, and since the second handle 22 is close to the middle position of the case body 5, the user can lift the case body 5 through the second handle 22, ensuring the balance of the case body 5.

[0052] As shown in FIG. 5, the case body 5 is provided with an accommodation groove 51 for accommodating the handle assembly 2 and the support part 3, and the accommodation groove 51 communicates with the mounting groove 52. The size of the accommodation groove 51 is equal to or larger than the size of the handle assembly 2 and the support part 3. The accommodation groove 51 can prevent the handle assembly 2 and the support part 3 from protruding from the case body 5 and increasing the overall volume of the suitcase 200. When calculating the size of the suitcase 200, the handle, wheels, etc. of the suitcase 200 are usually taken into consideration, so that the suitcase 200 has a large capacity without the trolley 100 protruding from the case body 5 and without changing the overall size of the suitcase 200. In addition, when the size of the accommodation groove 51 is larger than the size of the handle assembly 2, there is a certain distance between the second handle 22 and the inner wall of the accommodation groove 51, making it easier for the user to hold the second handle 22.

[0053] Of course, the above-mentioned trolley 100 can also be used in other devices with push-pull function, such as trolley backpacks, trolley audio systems, carts, etc., and the present invention is not particularly limited thereto.

[0054] Each of the technical features of the above-mentioned embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of each of the technical features in the above-mentioned embodiments are described. However, as long as the combinations of these technical features are not contradictory, all of them should be considered to be within the scope of the present specification.

[0055] The above embodiments only represent some embodiments of the present invention, and the description is relatively specific and detailed, but should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make some variations and modifications without departing from the spirit and scope of the present invention, all of which belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the appended claims. [Explanation of symbols]
