The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the associated listed items.

[0045] When people go out, they may need to carry a single-shoulder bag, a backpack, a computer bag or a shopping bag, etc. while pulling a luggage trolley, which is inconvenient. In traditional luggage, some have hooks on the side of the luggage or the side of the trolley for hanging bags. However, when people walk with the luggage, they are likely to hit the bag or the hook, causing the bag to fall off, which is inconvenient to use.

[0046] To solve the above problems, as shown in FIGS. 1-11, the present application first provides a trolley 100 to facilitate users to hang bags on the luggage.

[0047] As shown in FIGS. 3-5, specifically, the pull rod 100 comprises the linkage assembly 10, the handle assembly 20, and the hook 30, wherein: the handle assembly 20 comprises a first handle 21 extending along a first preset direction (±X-axis direction as shown in FIG. 3) and a second handle 22 connected with the first handle 21 and extending along a horizontal direction (XY plane as shown in FIG. 3), the first handle 21 being connected with the linkage assembly 10; the hook 30 is arranged on a side of the second handle 22 away from the first handle 21 and can rotate relative to the second handle 22, the hook 30 having a storage state and a use state, in the storage state, the hook 30 extends along the first preset direction, and in the use state, part of the hook 30 protrudes from the upper surface of the second handle 22.

[0048] In the pull rod 100 provided by the embodiment of the present application, when a bag needs to be hung, the hook 30 is rotated to the use state as shown in FIG. 5, so that part of the hook 30 protrudes from the upper surface of the second handle 22, and the user can hang the bag strap or handle on the hook 30, thereby ensuring the stability of the bag hung on the hook 30, so that the user does not need to hold the bag while pulling the pull rod 100 of the luggage. Since the hook 30 is arranged on the handle assembly 20, compared with the bag hung on the side of the luggage which is relatively high in height, the user can avoid bumping into the bag or the hook 30 when walking with the luggage, thereby avoiding affecting the normal walking of the user. In addition, since the hook 30 is arranged on the side of the second handle 22 away from the first handle 21, the hook 30 can also avoid affecting the user's grip on the first handle 21. When the bag does not need to be hung, the hook 30 is rotated to the storage state as shown in FIG. 4, so that the hook 30 extends along the ±X-axis direction, thereby avoiding the overall size of the luggage from being increased due to the fact that the hook 30 always protrudes from the outer surface of the first handle 21 or the luggage, or the user from easily bumping into the hook 30, so as to ensure the regular appearance of the hook and the luggage.

[0049] In the illustrated embodiment, in the use state, the extension direction of the hook 30 is perpendicular to the ±X-axis, i.e. the ±Z-axis direction as shown in FIG. 5. In the case where the overall length of the hook 30 is constant, when the hook 30 extends along the vertical direction, the longer the length of the part of the hook 30 protruding from the upper surface of the second handle 22, the more stable the bag hung on the hook 30. In addition, in order to avoid increasing the overall volume of the pull rod 100 or the luggage, the plane where the first handle 21 and the second handle 22 are located is parallel to the XY plane as shown in FIG. 3. In other embodiments, in the use state, the extension direction of the hook 30 can also form an acute angle or an obtuse angle with the ±X-axis, as long as part of the hook 30 protrudes from the upper surface of the second handle 22 and the protruding part can ensure the stability of the hung bag, which is not specifically limited in the embodiment of the present application.

[0050] As shown in Figures 5 and 7, the hook 30 includes a rotating portion 31 and a hook portion 32 that are interconnected. The rotating portion 31 is rotatably connected to the second handle 22. When in use, at least a portion of the hook portion 32 protrudes from the upper surface of the second handle 22. Alternatively, the rotating portion 31 may be configured as a rotating shaft, with a rotating hole provided on the side of the second handle 22 facing away from the first handle 21, into which the rotating shaft is inserted and capable of rotating relative to the second handle 22. Alternatively, the rotating shaft may be provided protruding from the side of the second handle 22 facing away from the first handle 21, with the rotating portion 31 provided with a rotating hole, into which the rotating shaft is inserted, and the rotating portion 31 is capable of rotating relative to the rotating shaft. The hook 30 has a simple structure and is easily controlled by the user to switch the hook 30 between a stored state and a use state.

[0051] As shown in Figures 4, 5 and 7, there are two hook parts 32, which are relatively arranged on both sides of the rotating part 31. In the use state, any hook 30 protrudes from the upper surface of the second handle 22. When the hook 30 is in the storage state shown in Figure 4, the user can control the hook 30 to rotate along the +W or -W direction to the use state shown in Figure 5, so that any hook part 32 protrudes from the upper surface of the second handle 22. Similarly, the user can also control the hook 30 to rotate along the -W or +W direction to the storage state in the use state. Users can control the rotation direction of the hook 30 according to their own habits, so as to facilitate use by different groups of people. In addition, the symmetrical arrangement of the two hook parts 32 can also improve the overall aesthetics of the hook 30 and the pull rod 100.

[0052] As shown in Figures 4, 5, and 8, in the retracted state, the dimension a of the hook portion 32 along the first predetermined direction satisfies 20mm≤a≤100mm. Here, a can be any value within the range of 20mm to 100mm, such as 20mm, 21mm, 22mm, ..., 99mm, or 100mm. When a ≥ 20mm, the portion of the hook portion 32 protruding from the upper surface of the second handle 22 ensures the stability of the bag when in use. When a ≤ 100mm, the hook portion 32 is prevented from being too long and protruding beyond the ends of the first handle 21 when retracted, thereby ensuring the neat appearance of the pull rod 100.

[0053] As shown in Figures 6 and 7, one of the second handle 22 and the hook 30 is provided with an arcuate groove 221, and the other is provided with a slider 33. When the hook 30 rotates relative to the second handle 22, the slider 33 slides within the arcuate groove 221. The slider 33 cooperates with the arcuate groove 221 to limit the rotation range of the hook 30, thereby facilitating user control of the hook 30. At least when the hook 30 is rotated to the use position, the slider 33 can abut against the sidewall of one end of the arcuate groove 221 to limit further sliding of the hook 30 relative to the second handle 22, thereby facilitating the user's alignment of the hook 30 when the hook 30 is rotated to the use position.

[0054] As shown in FIGS. 6-7, the bottom wall of the arc-shaped sliding groove 221 is spaced apart with a plurality of limiting grooves 222, and the sliding block 33 is clamped in the corresponding limiting groove 222 in the storage state and the use state. The cooperation of the sliding block 33 and the limiting groove 222 can improve the stability and reliability of the hook 30 in the use state and the storage state, thereby improving the stability and reliability of the bag hung on the hook 30, and avoiding the bag from falling and being damaged due to the accidental rotation of the hook 30 relative to the second handle 22. Moreover, when the sliding block 33 is clamped in the limiting groove 222, it can also remind the user to rotate in place, thereby further facilitating the user to align the hook 30.

[0055] When it is necessary to adjust the hook 30 to switch between the storage state and the use state, the hook 30 is first pulled outward away from the second handle 22, so that the sliding block 33 is disengaged from the limiting groove 222, and then the hook 30 is controlled to rotate relative to the second handle 22 along the ±W direction, so that the sliding block 33 slides in the arc-shaped sliding groove 221. When the hook 30 is rotated in place, the sliding block 33 corresponds to the limiting groove 222, the hook 30 is pushed towards the second handle 22, so that the sliding block 33 is clamped in the corresponding limiting groove 222, and the adjustment is completed.

[0056] In the illustrated embodiment, the central angle of the arc-shaped sliding groove 221 is 180°, and three limiting grooves 222 are provided, and the central angle between the adjacent two limiting grooves 222 is 90°. When the hook 30 is in the storage state, the sliding block 33 is clamped in the middle limiting groove 222, and when the hook 30 is rotated to the use state, the sliding block 33 is clamped in one of the limiting grooves 222 on the two sides.

[0057] Further, the pull rod 100 further comprises a resilient member (not shown) provided between the hook 30 and the second handle 22. When the sliding block 33 is disengaged from the limiting groove 222, the resilient member is stretched. When the hook 30 is pulled outward away from the second handle 22, the sliding block 33 is disengaged from the limiting groove 222, and the resilient member is stretched. When the hook 30 is rotated relative to the second handle 22 along the ±W direction to correspond to the limiting groove 222, the hook 30 can slide towards the second handle 22 under the action of the elastic force of the resilient member, so that the sliding block 33 is clamped in the corresponding limiting groove 222, thereby the user can be relieved from the step of aligning the sliding block 33 with the limiting groove 222 and pushing the hook 30 towards the second handle 22, facilitating the user to operate. Of course, when the sliding block 33 is clamped in the limiting groove 222, the resilient member can also be in the stretched state, so as to improve the stability and reliability of the hook 30 in the storage state and the use state.

[0058] Further, a guide slope is arranged between the sidewall of the limiting groove 222 and the bottom wall of the arc-shaped sliding groove 221, when the sliding block 33 is clamped in the limiting groove 222, the user can exert a larger torsional force on the hook 30, so that the hook 30 can slide away from the second handle 22 under the action of the guide slope while rotating relative to the second handle 22, thereby making the sliding block 33 out of the limiting groove 222, so as to save the step of the user pulling the hook 30 away from the second handle 22, facilitating the user to operate.

[0059] As shown in FIG. 4 and FIG. 8, the second handle 22 includes a handle section 223 and two connecting sections 224 respectively connected with two ends of the handle section 223, the handle section 223 is arranged apart from the first handle 21 along a second preset direction (the ±Y axis direction shown in FIG. 4), and the hook 30 is arranged on the side of the handle section 223 away from the first handle 21; the ends of the two connecting sections 224 away from the handle section 223 are respectively connected with the two ends of the first handle 21, so that the first handle 21 and the second handle 22 are arranged to form a storage space. The user can place other articles such as a cup in the storage space formed by the first handle 21 and the second handle 22, and the first handle 21 and the second handle 22 are used to limit the cup to prevent the cup from falling, so that the user does not need to hold the cup all the time, and the user's leg will not be hit by the cup when walking while pulling the luggage, which is convenient to use. Further, compared with placing the cup on the side of the luggage, the cup is placed in the storage space which is higher in height, facilitating the user to take, and also playing a role of reminding the user, so that the bottle or cup is not easy to be forgotten. It can be understood that the outer diameter of most cups gradually increases from the bottom to the cup mouth, and the diameter of part of the area at the bottom of the cup needs to be smaller than the distance between the first handle 21 and the second handle 22, and the diameter of the remaining part of the area needs to be larger than the distance between the first handle 21 and the second handle 22, so that the cup can pass through the storage space and be arranged between the first handle 21 and the second handle 22.

[0060] As shown in FIG. 8, the side of the second handle 22 facing the storage space is provided with a recess 225. The recess 225 can be arc-shaped, which can limit the position of the cup when the cup is placed in the storage space, avoiding the cup from falling or sliding along the ±X axis direction. The side of the second handle 22 away from the storage space can be provided with an arc-shaped structure corresponding to the recess 225, so as to be thinner in thickness and reduce the overall weight of the second handle 22, and the hook 30 can also be provided with an arc-shaped structure fitting the side of the second handle 22 away from the storage space, so that the structure of the handle assembly 20 and the hook 30 is more beautiful. Of course, the side of the first handle 21 facing the storage space can also be provided with a recess 225, which limits the position of the cup while making the user more comfortable when gripping the first handle 21.

[0061] As shown in FIG. 4 and FIG. 8, in the illustrated embodiment, both ends of the handle section 223 are provided with a hanging groove 2231 extending along the first preset direction, and the projections of the two hanging grooves 2231 along the first preset direction coincide. When the straps or handles of the bag are long, the straps or handles of the bag can be hung at the two hanging grooves 2231, and the two hanging grooves 2231 can provide two support points for the straps or handles of the bag, and the distance between the two support points is large, thereby improving the stability of the bag and reducing damage to the straps or handles of the bag. In another embodiment, both connection sections 224 are provided with a hanging groove 2231 extending along the first preset direction, and the projections of the two hanging grooves 2231 along the first preset direction coincide.

[0062] Of course, the two hanging grooves 2231 can also be used to place electronic devices such as mobile phones and tablets, and the two hanging grooves 2231 can improve the stability of supporting electronic devices, avoid electronic devices from falling or falling, and also do not limit the size of electronic devices along the ±X axis direction. When the hanging groove 2231 is used to place electronic devices, due to the limited depth of the hanging groove 2231, the hook 30 can be turned to the use state, so that the hook portion 32 can support the electronic device at the rear side, further improving the stability and safety of the electronic device during use.

[0063] Among them, the handle section 223 and the hook 30 can be preferably metal pieces to ensure the strength of the handle section 223 and the hook 30, and also ensure the reliability when the bag is hung or the electronic device is placed. The connection section 224 can be made of the same material as the handle section 223, for example, the handle section 223 and the connection section 224 are provided as an integrated structure to ensure the connection strength; the connection section 224 can also be made of a different material from the handle section 223 to reduce the overall weight of the handle assembly 20.

[0064] As shown in FIG. 4, the upper edge of the hanging groove 2231 is inwardly convexly provided with a limiting rib 2232. Among them, the limiting rib 2232 extends along the ±X axis direction and is convexly provided from one side edge of the hanging groove 2231 to the other side edge. The limiting rib 2232 can reduce the opening size on the upper side of the hanging groove 2231, avoid the straps or handles of the bag from accidentally coming out of the hanging groove 2231, and also improve the stability when the electronic device with a relatively thin thickness is erected in the hanging groove 2231.

[0065] As shown in FIG. 11, the width b of the hanging groove 2231 along the second preset direction satisfies 10mm≤b≤15mm. Wherein, b can be 10mm, 10.5mm, 11mm, …, 14mm, 15mm, or any value within the range of 10mm to 15mm. When the size of the hanging groove 2231 along the ±Y axis direction satisfies 10mm to 15mm, it can ensure that bags with different width of straps or handles can be hung in the hanging groove 2231, and also ensure that electronic devices such as mobile phones and tablets, or electronic devices with protective cases, can be placed in the hanging groove 2231, and the application range is wide.

[0066] As shown in FIG. 6, the depth c of the hanging groove 2231 satisfies 12mm≤c≤38mm. Wherein, c can be 12mm, 13mm, 14mm, …, 37mm, 38mm, or any value within the range of 12mm to 38mm. When the size of the hanging groove 2231 along the ±Z axis direction satisfies 12mm to 38mm, it can ensure the stability of the straps or handles of the bag when hung in the hanging groove 2231, and avoid the straps or handles of the bag from accidentally coming out of the hanging groove 2231, and also ensure the stability of the electronic devices such as mobile phones and tablets when placed in the hanging groove 2231, and avoid the electronic devices from toppling or falling. At the same time, limiting the size of the hanging groove 2231 in each direction can also avoid the overall size of the trolley 100 from being too large due to the size of the second handle 22 being too large.

[0067] As shown in FIG. 3 and FIG. 9, the connecting rod assembly 10 includes a base 11 and a telescopic rod 12 extending from the base 11, and the end of the telescopic rod 12 away from the base 11 is connected with the first handle 21.

The first handle 21 is provided with a button 211 for controlling the telescopic rod 12 to be telescopic, and the user can control the telescopic rod 12 to be telescopic by pressing the button 211. The handle assembly 20 and the hook 30 can adjust the height under the action of the telescopic rod 12 to be telescopic, so as to facilitate users of different heights to use in different environments. For example, when the user walks while pulling the luggage case by the handle assembly 20, the telescopic rod 12 can be pulled up. When the telescopic rod 12 is in the retracted state, the upper surface of the handle assembly 20 is flush with the upper surface of the case body 200 of the luggage case, so as to avoid increasing the overall volume of the luggage case.

[0068] Wherein, the number of the telescopic rod 12 can be two, and the two telescopic rods 12 are arranged along the ±X axis direction and spaced apart, and the ends of the two telescopic rods 12 away from the base 11 are respectively connected with the two ends of the first handle 21. Of course, the number of the telescopic rod 12 can also be one, and the end of the telescopic rod 12 away from the base 11 is connected with the middle position of the first handle 21, as long as it can ensure the overall strength of the trolley 100 and the stability of the handle assembly 20 when lifting along the ±Z axis direction, which is not limited in the embodiments of the present application.

[0069] As shown in FIG. 3, FIG. 9 and FIG. 10, the telescopic rod 12 comprises an outer rod 121, inner rods (not shown) and a limiting assembly 122. The number of inner rods can be one, two or more, and the inner rods are sequentially sleeved from inside to outside, with the cross-sectional size of the inner rods gradually increasing. The cross-sectional size of the outer rod 121 is larger than that of the outermost inner rod. One end of the outer rod 121 is connected with the base 11, and the end of the innermost inner rod away from the base 11 is connected with the first handle 21. The number of limiting assemblies 122 corresponds to the number of inner rods, and adjacent inner rods or the outermost inner rod and the outer rod 121 are connected by one limiting assembly 122. The limiting assembly 122 has a limiting state and an unlocked state. In the limiting state, the telescopic rod 12 cannot be telescoped along the ±Z axis direction, and in the unlocked state, the inner rods can be telescoped along the ±Z axis direction relative to the outer rod 121. The button 211 on the first handle 21 is used to control the plurality of limiting assemblies 122 to be synchronously switched between the limiting state and the unlocked state.

[0070] For ease of description, the following describes an example in which the telescopic rod 12 comprises one inner rod and one limiting assembly 122. One end of the outer rod 121 is connected with the base 11, and the inner rod is slidably arranged in the outer rod 121, with the end of the inner rod away from the base 11 being connected with the first handle 21. The side wall of the outer rod 121 is provided with a plurality of limiting holes 1211 arranged at intervals along the length direction of the telescopic rod 12, and the limiting assembly 122 is arranged in the inner rod and comprises a sliding piece 1221 and a limiting piece 1222 protruding from the sliding piece 1221. The sliding piece 1221 can slide relative to the inner rod along a third preset direction (the ±V axis direction shown in FIG. 10) to make the limiting piece 1222 slide into or out of any limiting hole 1211. The ±V axis direction is parallel to the XY plane and can be parallel to the ±X axis. When the user presses the button 211, the button 211 can drive the sliding piece 1221 to slide along the -V axis direction to make the limiting piece 1222 out of the limiting hole 1211, and the limiting assembly 122 is in the unlocked state, and the inner rod can slide and telescope relative to the outer rod 121 along the ±Z axis direction. After the user releases the button 211, the button 211 can automatically reset and drive the sliding piece 1221 to slide along the +V axis direction to make the limiting piece 1222 inserted into the corresponding limiting hole 1211, and the limiting assembly 122 is in the limiting state, and the inner rod cannot slide and telescope relative to the outer rod 121 along the ±Z axis direction. The limiting assembly 122 is used to improve the stability of the telescopic rod 12 at various lengths, and avoid the bag hung on the hook 30 or the handle assembly 20 and the cup or electronic device placed on the handle assembly 20 from falling due to accidental contraction of the telescopic rod 12.

[0071] As shown in FIGS. 10-11, the sliding piece 1221 is provided with a limiting sliding groove 12211, and the limiting assembly 122 further includes a driving piece 1223 capable of sliding relative to the inner rod along the length direction of the telescopic rod 12 (the ±Z-axis direction shown in FIG. 10), the driving piece 1223 includes a sliding part 12231 in sliding cooperation with the limiting sliding groove 12211; when the driving piece 1223 slides along the length direction of the telescopic rod 12, the sliding part 12231 slides in the limiting sliding groove 12211, so as to drive the sliding piece 1221 to slide relative to the inner rod along the third preset direction. When the user presses the button 211, the button 211 can drive the driving piece 1223 to slide along the -Z direction, and the sliding part 12231 slides in the limiting sliding groove 12211, so as to drive the sliding piece 1221 to slide along the -V-axis direction, and the limiting piece 1222 is out of the limiting hole 1211. After the user releases the button 211, the button 211 automatically resets and drives the driving piece 1223 to slide along the +Z direction, and the sliding part 12231 slides in the limiting sliding groove 12211, so as to drive the sliding piece 1221 to slide along the +V-axis direction, and the limiting piece 1222 is inserted into the corresponding limiting hole 1211. The driving piece 1223 and the sliding piece 1221 have simple structure, and the overall volume of the telescopic rod 12 is avoided from being increased.

[0072] As shown in FIG. 11, the limiting sliding groove 12211 includes a limiting section 12211a and an inclined section 12211b in communication with each other, the limiting section 12211a extends along the length direction of the telescopic rod 12, and when the sliding part 12231 slides in the inclined section 12211b, the sliding piece 1221 slides relative to the inner rod along the third preset direction. In the limiting state, the sliding part 12231 is located in the limiting section 12211a, and the sliding piece 1221 cannot slide along the ±V-axis direction, at this time, even if the user shakes the telescopic rod 12 greatly, or presses the limiting piece 1222 outside the outer rod 121, the limiting piece 1222 will not be out of the limiting hole 1211, and the telescopic rod 12 cannot be telescoped; only when the user presses the button 211 on the first handle 21, the driving piece 1223 can be driven to slide along the -Z-axis direction, and the sliding part 12231 will first slide in the limiting section 12211a for a distance, and then slide from the limiting section 12211a to the inclined section 12211b, so as to drive the sliding piece 1221 to slide along the -V-axis direction, and the limiting piece 1222 is out of the limiting hole 1211. Thus, the telescopic rod 12 can be further prevented from being accidentally telescoped, and the safety of the use of the pull rod 100 is improved.

[0073] As shown in FIGS. 10-11, the limiting assembly 122 further comprises a base 1224 provided with a sliding groove 12241 extending along the ±V-axis direction, and the sliding piece 1221 is slidably arranged in the sliding groove 12241 to limit the sliding direction of the sliding piece 1221, so that the sliding piece 1221 can only slide along the ±V-axis. The limiting assembly 122 further comprises a stop piece 1225 arranged in the sliding groove 12241 and fixed relative to the base 1224, and the sliding piece 1221 is provided with a stop sliding groove 12212 extending along the ±Z-axis direction, and the stop piece 1225 can slide in the stop sliding groove 12212. When the sliding piece 1221 slides to the limiting state and the unlocking state, the two side surfaces of the stop piece 1225 can abut against the two ends of the stop sliding groove 12212, respectively, to limit the continuous sliding of the sliding piece 1221, so as to limit the sliding range of the sliding piece 1221.

[0074] As shown in FIGS. 1-2, the luggage provided by the embodiments of the present application further comprises a box body 200 and the above-mentioned pull rod 100, and the pull rod 100 is arranged on the box body 200. Specifically, the top wall of the box body 200 is provided with a first accommodating groove 201 for accommodating the handle assembly 20, and the size of the first accommodating groove 201 is greater than or equal to the size of the handle assembly 20. The first accommodating groove 201 can avoid the protrusion of the handle assembly 20 from the box body 200 to increase the overall volume of the luggage. Since the handle, wheels and the like of the luggage are usually taken into account when calculating the size of the luggage, the protrusion of the pull rod 100 from the box body 200 enables the luggage to have a larger capacity without changing the overall size. In addition, there is a certain gap between the first handle 21 and the second handle 22 and the bottom wall of the first accommodating groove 201, so as to facilitate the user to grasp the first handle 21, and when a cup is placed in the storage space, the bottom wall of the first accommodating groove 201 can also support the cup.

[0075] As shown in FIGS. 1-2, the side wall of the box body 200 is provided with a second accommodating groove 202 in communication with the first accommodating groove 201 and extending along the height direction (the ±Z-axis direction shown in FIG. 1) of the luggage, and the bottom wall of the box body 200 is provided with a third accommodating groove 203 in communication with the second accommodating groove 202, the telescopic rod 12 is embedded in the second accommodating groove 202, and the base 11 is embedded in the third accommodating groove 203. The pull rod 100 is arranged on the outside of the box body 200, and the handle assembly 20 and the base 11 are arranged on the top wall and the bottom wall of the box body 200, respectively, so that the telescopic rod 12 can reach the longest length, thereby extending the adjustable length of the inner rod and the outer rod 121, so that the luggage can be suitable for users of different heights and different use environments, further expanding the application range.

[0076] As shown in FIGS. 1-2, the inner wall of the third container 203 and the base 11 form a handle portion with an opening. When the luggage is in a flat state, i.e., the side of the box body 200 provided with the telescopic rod 12 is in a horizontal state, the handle portion and the first handle 21 are at the same height, and the user can hold the first handle 21 and the handle portion with both hands to facilitate lifting the luggage.
