The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the relevant listed items.

[0038] When traveling, people may find themselves holding a drink bottle or coffee cup while pulling the luggage handle, which can be inconvenient. Some luggage cases in the related art have cup holders on the side of the case or on the side of the handle, allowing users to place bottles or cups in the holders while waiting for a bus or walking. However, when pulling the suitcase, the user's legs can easily bump into the cup holders, making it difficult to use. Furthermore, due to the height restrictions of suitcases, placing bottles or cups in the cup holders on the side of the case requires users to squat down to retrieve them, making them easily forgotten.

[0039] In order to solve the above problems, as shown in Figures 1 to 4, the present application first provides a pull rod 100, which can facilitate users to place bottles or cups, is not easily forgotten, is not prone to collision, and is easy to use.

[0040] As shown in FIG. 1 to FIG. 4 , the first preset direction is defined as the ±X axis direction, the second preset direction is defined as the ±Y axis direction, and the extending direction of the connecting rod assembly 1 is defined as the ±Z axis direction.

[0041] As shown in Figure 1, specifically, the pull rod 100 includes a connecting rod assembly 1, a handle assembly 2 and a support member 3, wherein: the handle assembly 2 is arranged on the connecting rod assembly 1, and the handle assembly 2 includes a first handle 21 and a second handle 22 arranged at intervals along the ±X axis direction; the support member 3 is arranged on the handle assembly 2, and the support member 3 is recessed toward the side toward the connecting rod assembly 1, that is, the support member 3 is recessed toward the direction toward the -Z axis, and forms a storage space 33 with the first handle 21 and the second handle 22, and bottles, cups and other items can be placed in the storage space 33.

[0042] As previously mentioned, luggage cases in the related art often feature cup holders located on the sides of the suitcase or on the side of the handle. This can easily cause a user's legs to bump into the cup holders while pulling the suitcase, making it inconvenient to use. In contrast, the handle 100 provided in the present embodiment allows users to place other items, such as bottles or cups, within the storage space 33 formed by the first handle 21, the second handle 22, and the support member 3. The support member 3 supports the bottle or cup, while the first and second handles 21, 22 hold it in place to prevent it from falling. This eliminates the need to constantly hold the bottle or cup. Because the bottle or cup is placed between the first and second handles 21, 22, the user's legs won't bump into it while pulling the suitcase 200, making it easier to use. Furthermore, placing the bottle or cup in the storage space 33 is higher than placing it on the side of the suitcase 200, making it easier for the user to reach and also serving as a reminder, preventing the bottle or cup from being forgotten.

[0043] At the same time, the pull rod 100 provided in the embodiment of the present application utilizes the first handle 21 and the second handle 22 to form a storage space 33, and there is no need to set an additional structure on the connecting rod assembly 1, thereby avoiding the connecting rod assembly 1 of the pull rod 100 from occupying too much space on devices such as the suitcase 200, thereby increasing its internal capacity without changing the overall volume of the device such as the suitcase 200.

[0044] As shown in Figures 1 and 2, in the illustrated embodiment, the linkage assembly 1 includes a connecting rod 12 and two telescopic rods 11 connected to each end of the connecting rod 12. The ends of the telescopic rods 11, distal from the connecting rod 12, are telescopic ends 111, which are capable of extending and retracting relative to the connecting rod 12 along the ±Z-axis. The telescopic ends 111 of the two telescopic rods 11 are respectively connected to the ends of a first handle 21. The first handle 21 is provided with a button 211 for controlling the extension and retraction of the telescopic rods 11. The user can press the button 211 and control the extension and retraction of the telescopic rods 11 via the first handle 21. The handle assembly 2 and support member 3 are also height-adjustable by the extension and retraction of the telescopic rods 11. When a user pulls a suitcase 200 or other device using the first handle 21, the telescopic rod 11 is typically pulled higher, and bottles or cups placed in the storage space 33 are also raised along with the handle assembly 2 and support member 3, making them easier for the user to reach. When the telescopic rod 11 is in the retracted state, the user can pick up the suitcase 200 or other devices by the second handle 22. Moreover, since the second handle 22 is closer to the middle position of the suitcase 200 or other devices than the first handle 21, it can also ensure that the suitcase 200 or other devices remain balanced when being picked up by the second handle 22.

[0045] In another embodiment, the telescopic ends 111 of the two telescopic rods 11 may be connected to the first handle 21 and the second handle 22 respectively; and the two telescopic rods 11 may be provided separately without being connected by the connecting rod 12. Of course, in other embodiments, the connecting rod assembly 1 may also 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 pull rod 100 can be guaranteed.

[0046] As shown in FIG1 , the handle assembly 2 further includes a connector 23 connected to the first handle 21 and the second handle 22 at either end. There are at least two connectors 23, which are spaced apart along the ±Y-axis directions. In the illustrated embodiment, there are two connectors 23, one at each end of the first handle 21 and one at each end of the second handle 22. The first handle 21, the second handle 22, and the two connectors 23 form a rectangular structure. The first handle 21 and the second handle 22 are used to restrict the position of a bottle or cup placed in the storage space 33 along the ±X-axis directions, while the connectors 23 are used to restrict the position of a bottle or cup placed in the storage space 33 along the ±Y-axis directions to prevent the bottle or cup from tipping over or falling. Of course, in other embodiments, the number of connectors 23 may be three, four, or more, and one or more bottles or cups can be placed between two adjacent connectors 23. As long as the position of the bottles or cups can be restricted, this embodiment of the present application is not particularly limited.

[0047] Among them, the connecting member 23 and the first handle 21, as well as the connecting member 23 and the second handle 22 can be connected by an arc segment. The arc segment can avoid stress concentration and improve the strength of the handle assembly 2, so that the pull rod 100 can meet the strength requirements of devices such as the suitcase 200.

[0048] As shown in FIG2 , in one embodiment, the support member 3 includes a U-shaped support portion 31 and two connecting portions 32 that are fixed to each other. The support portion 31 can extend along the ±Y axis, and the two connecting portions 32 are connected to the two connecting members 23 at their ends, which are distal to the support portion 31. The support portion 31 is used to support items such as bottles or cups placed in the storage space 33. The connecting portions 32 are used to connect the support portion 31 to the handle assembly 2, while also further restricting the position of the bottles or cups to prevent them from falling. The number of support members 3 can be one, and the support member 3 is positioned in the middle of the connecting member 23, leaving a large space between the support member 3 and both the first handle 21 and the second handle 22. This ensures that bottles or cups placed in the storage space 33 do not fall while also preventing the user from gripping the first and second handles 21 and 22. Of course, the number of support members 3 can also be multiple, with multiple support members 3 spaced apart along the ±X axis, as long as they do not hinder the user's grip on the first and second handles 21 and 22. This embodiment of the present application is not particularly limited here.

[0049] In another embodiment, the support portion 31 may also extend along the ±X axis direction, and the two connecting portions 32 are connected to the first handle 21 and the second handle 22 at one end away from the support portion 31, and the number of support members 3 may be one, two, or more, and the multiple support members 3 are arranged at intervals along the ±Y axis direction. Alternatively, the multiple support members 3 may be arranged crosswise, that is, some support portions 31 extend along the ±X axis direction, and other support portions 31 extend along the ±Y axis direction, and the multiple support portions 31 are connected to each other in a cross shape; the connecting portions 32 corresponding to the support portions 31 extending along the ±X axis direction are connected to the first handle 21 and the second handle 22, and the connecting portions 32 corresponding to the support portions 31 extending along the ±Y axis direction are connected to the connecting member 23. As long as it is ensured that the bottles or cups placed in the storage space 33 will not fall and will not affect the user's grip on the first handle 21 and the second handle 22, the embodiment of the present application does not impose any specific restrictions here.

[0050] As shown in Figures 3 and 4, the distance a between the first handle 21 and the second handle 22 satisfies 50mm≤a≤80mm. This allows the user to easily grasp the first handle 21 and the second handle 22, and bottles or cups of varying diameters can be placed in the storage space 33 without causing significant shaking. The distance b between the two connectors 23 satisfies 100mm≤b≤200mm. This allows two or more bottles or cups to be placed side by side in the storage space 33 when placed vertically, or shorter bottles or cans can be placed horizontally, providing a wide range of applications. The depth c of the storage space 33 satisfies 10mm≤c≤60mm, where the depth of the storage space 33 is the dimension of the storage space 33 along the ±Z axis. This ensures the stability of bottles or cups placed in the storage space 33, preventing them from falling. At the same time, limiting the size of the storage space 33 in all directions can also prevent the pull rod 100 from being too large and occupying too much space inside a device such as a suitcase 200.

[0051] As shown in FIG2 , 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. Since the center of gravity of an electronic device 34, such as a mobile phone or tablet computer, is relatively high when placed vertically, making it prone to tipping over, the mobile phone or tablet computer can be placed in the first groove 311 when the electronic device 34 needs to be used vertically. The storage space 33 has a certain depth, and when the mobile phone or tablet computer is placed in the first groove 311, the electronic device 34 rests on the first handle 21 or the second handle 22, thereby ensuring the stability and safety of the electronic device 34, such as the mobile phone or tablet computer, and preventing the electronic device 34 from toppling over or falling.

[0052] As shown in Figures 3 and 4, the width d of the first groove 311 along the ±X axis satisfies 10mm≤d≤15mm, and the length e of the first groove 311 along the ±Y axis satisfies 60mm≤e≤190mm. This ensures that electronic devices 34, such as mobile phones and tablets, of varying widths and thicknesses, or even those with protective cases, can fit within the first groove 311, broadening its applicability. The depth f of the first groove 311 satisfies 5mm≤f≤25mm, where the depth of the first groove 311 refers to the dimension of the first groove 311 along the ±Z axis. This ensures the stability of the electronic device 34, such as a mobile phone or tablet, when placed within the first groove 311, preventing it from slipping. Furthermore, limiting the dimensions of the first groove 311 in all directions prevents the support portion 31 from being too large, which could lead to an oversized overall pull rod 100 or hinder the user's grip on the first and second handles 21 and 22.

[0053] As shown in Figures 2 and 6, each connector 23 is provided with a second groove 231 for accommodating an electronic device 34 at the same location. Along a second predetermined direction, both ends of the second groove 231 extend to the edge of the connector 23. When an electronic device 34, such as a mobile phone or tablet, is to be used horizontally, it can be placed in the second groove 231. Because both ends of the second groove 231 extend to the edge of the connector 23, the second groove 231 does not restrict the size of the electronic device 34 along the ±Y axis when used horizontally. Furthermore, the multiple connectors 23 can improve the stability of the electronic device 34 placed in the second groove 231, preventing the electronic device 34 from tipping over or falling.

[0054] 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, it can be ensured that electronic devices 34 such as mobile phones and tablets of different thicknesses, or electronic devices 34 with protective cases can be placed in the second groove 231 and are not easy to slide in the second groove 231. The depth h of the second groove 231 satisfies 12mm≤h≤38mm. In this way, the stability of electronic devices 34 such as mobile phones and tablets when placed in the second groove 231 can be ensured, and the electronic devices 34 can be prevented from tipping over or falling. At the same time, limiting the dimensions of the second groove 231 in all directions can also prevent the connector 23 and the second handle 22 from being too large, which would cause the overall size of the pull rod 100 to be too large.

[0055] As shown in Figure 3, to ensure that a user can lift a device such as a suitcase 200 using 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, so that there is a certain gap between the second handle 22 and the device such as the suitcase 200 to facilitate the user's grasp of the second handle 22. When the first handle 21 and the second handle 22 are flush, the depth of the second groove 231 is the dimension of the inner wall surface of the second groove 231 on both sides along the ±Z axis. When the second handle 22 is slightly higher than the first handle 21, the depth of the second groove 231 is the dimension of the inner wall surface of the second groove 231 on the side closest to the second handle 22 along the ±Z axis.

[0056] As shown in Figures 2 and 3, the inner wall surface of the second groove 231 near the second handle 22 is configured as a sloped surface 2311. Thus, when an electronic device 34, such as a mobile phone or tablet, is placed in the second groove 231, it rests on the sloped surface 2311, ensuring the stability of the electronic device 34 while also improving user comfort. The sloped surface 2311 has an inclination angle θ of 0° ≤ θ ≤ 25°. When the mobile phone or tablet 34 is tilted within this angle range, the user can optimally and comfortably view the screen of the mobile phone or tablet 34.

[0057] As shown in Figures 2 and 4 , since users typically need to grasp the second handle 22 to lift items such as luggage 200, and items such as luggage 200 are often heavy, multiple recesses 221 are provided on the side of the second handle 22 facing the storage space 33. The recesses 221 adapt to the shape of the user's hand, making gripping the second handle 22 more comfortable. Furthermore, when a bottle or cup is placed vertically, the recesses 221 can restrict the position of the bottle or cup, preventing it from sliding along the ±Y axis. Of course, the first handle 21 can also be provided with multiple recesses 221 to further enhance gripping.

[0058] As shown in FIG2 , when people go out, they may need to carry a bag while pulling the handle 100 of the suitcase 200. The bag can easily collide with the suitcase 200 or the user's legs, making it difficult to move. Therefore, the handle 100 also includes a hook 4 provided on the handle assembly 2 or the support 3. The hook 4 can be used to hang other items such as bags, and the items hung on the hook 4 are not likely to collide with the suitcase 200 or the legs, thereby further facilitating the user's travel. The number of hooks 4 can be one, two, or more, and the hooks 4 can be provided on both the handle assembly 2 and the support 3, as long as they do not interfere with other structures. This embodiment of the present application does not impose any specific restrictions.

[0059] As shown in FIG5 , the present application further provides a luggage case 200 comprising a case 5 and the aforementioned pull rod 100, which is disposed within the case 5. A mounting groove 52 is provided on one side of the case 5, adapted to the shape of the connecting rod assembly 1. The connecting rod assembly 1 is embedded within the mounting groove 52, preventing the connecting rod assembly 1 from protruding from the case 5 and increasing the overall volume of the luggage case 200. Because a first handle 21 is connected to the connecting rod assembly 1, a user can use the first handle 21 to push the case 5. Because a second handle 22 is located near the center of the case 5, a user can use the second handle 22 to lift the case 5, ensuring its balance.

[0060] As shown in Figure 5, the case 5 is provided with a receiving groove 51 for accommodating the handle assembly 2 and the support member 3. The receiving groove 51 communicates with the mounting groove 52 and is larger than or equal to the size of the handle assembly 2 and the support member 3. The receiving groove 51 prevents the handle assembly 2 and the support member 3 from protruding from the case 5, thereby increasing the overall volume of the suitcase 200. Since the handle, wheels, and other components of the suitcase 200 are typically included in the calculation of the size of the suitcase 200, the absence of the pull rod 100 from the case 5 allows the suitcase 200 to have a larger capacity without changing its overall dimensions. Furthermore, when the receiving groove 51 is larger than the handle assembly 2, a certain distance is maintained between the second handle 22 and the inner wall of the receiving groove 51, making it easier for the user to grasp the second handle 22.

[0061] Of course, the above-mentioned pull rod 100 can also be used for other devices with push-pull functions, such as pull rod backpacks, pull rod speakers, and carts, and this application does not make any specific restrictions here.

[0062] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0063] The above-described embodiments merely represent several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
