[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments that a person skilled in the art can obtain without creative work fall within the scope of this utility model protection.

[0028] In the embodiments of the present utility model, if there are directional indications (e.g., up, down, left, right, front, back, top, bottom, inside, outside, vertical, lateral, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.), these directional indications are used only to explain the relative positional relationships and movement conditions between parts in a specific position (as shown in the drawings), and if the specific position changes, the directional indications also change accordingly.

[0029] Furthermore, where the embodiments of this utility model refer to "first" or "second," such terms are used for descriptive purposes only and are not intended to indicate or imply their relative importance or the number of technical features they refer to. Therefore, a feature defining a "first" or "second" may explicitly or implicitly include at least one feature. Furthermore, the technical solutions in each embodiment may be combined with each other, but this must be based on what a person skilled in the art can achieve. If a combination of technical solutions results in a contradiction or is impossible to achieve, the combination of technical solutions shall be deemed non-existent and not within the scope of protection claimed by this utility model.

[0030] This utility model proposes a cart 1 in which the basket and frame can be folded simultaneously.

[0031] In an embodiment of the present utility model, as shown in Figures 1 to 9, a cart 1 in which the basket and frame can be folded simultaneously includes a foldable basket 2, and the foldable basket 2 includes a basket main frame 23 and a basket support frame 24, and the basket support frame 24 includes at least two pipe bodies, and a first sliding seat 251 is engaged with the pipe bodies, and a stopper groove 2511 is provided in the first sliding seat 251.

[0032] The folding basket 2 further includes a foldable frame 3, the foldable frame 3 including an articulated frame 32 and a fixed frame 31 for supporting the foldable basket 2, the articulated frame 32 including a push rod 321, an interlocking rod 322, and a locking joint 33 for locking the interlocking rod 322. The folding basket 2 further includes a linking device 35 fitted to the fixed frame 31 for interlockingly folding the foldable frame 3 and the foldable basket 2, the linking device 35 including a second sliding seat 351 and an interlocking seat 352, the second sliding seat 351 including a stopper portion 3511 and a sliding portion 3512.

[0033] The following will provide a detailed description of the foldable basket 2 according to the utility model.

[0034] In this embodiment, the foldable basket 2 includes an articulated seat 21 and a handle 22, and the handle 22 is pivotally connected to the articulated seat 21 so as to rotate around the articulated seat 21. The foldable basket 2 further includes a basket main frame 23, and the basket main frame 23 includes an upper surrounding frame 231 and a lower surrounding frame 232, and a front surrounding pipe 2311 and a rear surrounding pipe 2312 included in the upper surrounding frame 231 are connected via the articulated seat 21. The foldable basket 2 further includes a basket support frame 24, and the basket support frame 24 is provided between the upper surrounding frame 231 and the lower surrounding frame 232, includes at least two pipe structures, and is used to support the basket main frame 23. The foldable basket 2 further includes a folding device 25, which includes a first sliding seat 251 movably fitted to the basket main frame 23 and a fixed seat 252 fixedly fitted to the basket main frame 23, and the pipe structure has one end connected to the fixed seat 252 and the other end connected to the first sliding seat 251; finally, the foldable basket 2 further includes a locking structure 26 for fixing the position of the first sliding seat 251.

[0035] However, the articulated seat 21 is connected to the basket main frame 23 via a pin hole. In this technical field, pin hole connections are considered to be prior art, and most of the component connections described below are pin connections. For the sake of convenience, the omitted component connections described below can all be understood as pin connections. Furthermore, since specific alternative connections are also considered to be prior art, details of preferred embodiments should be referred to the drawings.

[0036] In this preferred embodiment, the basket support frame 24 includes a first pipe body 241 and a second pipe body 242 that are connected to each other at an intersection, and a first hinge connection part 2451 is formed at the intersection, and the first pipe body 241 and the second pipe body 242 are contracted via the first hinge connection part 2451. The basket support frame 24 also includes a third pipe body 243 and a fourth pipe body 244 that are provided on opposite sides of the first pipe body 241 and the second pipe body 242, and a second hinge connection part 2452 is formed at the intersection. Note that, due to the objective need for basket structural symmetry, the structures of the third pipe body 243 and the fourth pipe body 244 that are provided on the opposite sides and the second hinge connection part 2452 are configured similarly to the first pipe body 241, the second pipe body 242, and the first hinge connection part 2451 described above, and the description thereof is for reference only.

[0037] In some other embodiments, basket support frame 24 does not need to have a crossing support pipe structure as in the preferred embodiment. Referring to FIGS. 5 and 6, in actual production, only first pipe body 241 and third pipe body 243 may be provided. Or, as a second case, only second pipe body 242 and fourth pipe body 244 may be provided. In these two cases, hinge connection 245 is not provided. As can be seen, in these two actual cases, basket main frame 23 is supported by two crossing pipe body structures on opposite sides. While basket support frame 24 in this structure tends to lack support, it can save material costs and achieve the general support effect required for the basket. Specifically, it is conceivable to install pipe bodies using a stronger material to avoid this drawback. This is prior art, and therefore will not be described in detail in this utility model.

[0038] As can be seen, in the above embodiment, in which only two pipe structures are provided, multiple pipe structures may be added on the same side to enhance stability. This embodiment differs from the cross-mounted configuration of the preferred embodiment in that the pipe structures on the same side are installed in parallel to achieve the deployed state when the basket needs to be used. Various parallel-mounted configuration embodiments can be referenced to the various cases of the preferred embodiment. The following content specifically describes a cross-mounted configuration embodiment, see below.

[0039] Specifically, in a preferred embodiment, four first sliding seats 251 are provided, two in a set, and each set of two first sliding seats 251 is fitted to the upper surrounding frame 231 and the lower surrounding frame 232 of the basket main frame 23, respectively. More specifically, all of the first sliding seats 251 are provided on the same side of the basket main frame 23. Furthermore, with the vertical direction of the hinge connection portion 245 as the axis of symmetry, the fixed seat 252 is provided on the other side of the basket main frame 23. See Figures 5 and 6. In this embodiment, the first sliding seats 251 are provided on the same side of the basket main frame 23, and each pair of first sliding seats 251 is provided on the rear surrounding pipe 2312, and the rear surrounding pipe 2312 corresponds to the position of the lower surrounding frame 232. As can be understood, the pair of first sliding seats 251 is respectively provided on the front surrounding pipe 2311, and the front surrounding pipe 2311 corresponds to the position of the lower surrounding frame 232, which is a simple substitution of the above content and is also a preferred embodiment of the present utility model.

[0040] Specifically, in another preferred embodiment, four first sliding seats 251 are provided, two in a set, and each pair of first sliding seats 251 is fitted to the upper surrounding frame 231 or the lower surrounding frame 232 of the basket main frame 23. More specifically, the first sliding seats 251 are provided on both sides of the basket main frame 23, and the fixed seats 252 are provided on the opposite side, with the horizontal direction of the hinge connection part 245 as the axis of symmetry. This embodiment is divided into two cases. The first and second first sliding seats 251 are both provided on the upper surrounding frame 231. The second and second two first sliding seats 251 are both provided on the lower surrounding frame 232. The first sliding seats 251 in these two cases slide in directions other than the articulated seat 21 to contract and lower the basket support frame 24. Since the specific structure is similar to that of the preferred embodiment, reference may be made to the description of the preferred embodiment. The details will not be explained.

[0041] In this embodiment, the locking structure 26 includes a locking seat 261 and a locking hook 262, which are hingedly connected. The locking structure 26 is provided at least adjacent to one of the first sliding seats 251. The locking hook 262 includes a hook portion 2621 and a pressing portion 2622. Specifically, see FIGS. 5 and 6. During folding, the pressing portion 2622 of the locking hook 262 is triggered to engage the hook portion 2621 of the locking hook 262 with the first sliding seat 251. More specifically, the hook portion 2621 is inserted into the stopper groove 2511 of the first sliding seat 251. By inserting the hook portion 2621 into the stopper groove 2511 and fixing the first sliding seat 251 in its current position, the first sliding seat 251 stops moving, i.e., the basket support frame 24 is in the unfolded state, and the foldable basket 2 remains in use.

[0042] Specifically, the locking structure 26 further includes a first elastic member 263 for resetting the locking hook 262. As shown in FIG. 5 , the first elastic member 263 is preferably a spring, with one end attached to the pressing portion 2622 of the locking hook 262 and the other end attached to the locking seat 261. By triggering the pressing portion 2622, the spring is compressed, causing the hook portion 2621 of the locking hook 262 to disengage from the stopper groove 2511, thereby unlocking the first sliding seat 251. At this time, the elasticity of the spring allows the locking hook 262 to quickly reset. In some other embodiments, the spring may be replaced with a resilient piece, such as rubber or sponge, having elastic properties, but this is prior art and will not be described in detail.

[0043] As can be seen, although one locking structure 26 is provided in this embodiment, two are preferably provided, each attached near the first sliding seat 251 on either side. Two locking structures 26 ensure safety and stability while fully realizing the technical effect of this utility model. In some other embodiments, more locking structures 26 may be provided for safety reasons. Specifically, a locking structure 26 may be provided near one first sliding seat 251 on each side of the foldable basket 2. Furthermore, the first sliding seat 251 that engages with the locking structure 26 needs to have a stopper groove 2511 for using the hook portion 2621, while the first sliding seat that does not need to engage with the locking structure 26 does not need to have a stopper groove 2511. In the case of multiple embodiments in which the basket support frame 24 is configured differently, the present description applies to the different embodiments.

[0044] In this embodiment, telescopic seats 27 for connecting the basket to the frame are attached to the bottom plate 233 provided below the lower surrounding frame 232, and there are two telescopic seats 27, one at each end of the bottom plate 233. The telescopic seats 27 include a seat body 271, a telescopic key 272 provided within the seat body 271, and a second elastic member 273, and are used to attach to a specific frame; by attaching the telescopic seats 27 to the frame, the basket can be placed more stably on the frame; the specific details of the telescopic seats 27 will be described later in conjunction with the foldable frame 3.

[0045] Specifically, with regard to the specific explanation of the telescopic seats 27 being attached to both ends of the bottom plate 233, in reality, the positions of the two telescopic seats 27 need only be on opposite sides passing through the center of the bottom plate 233, and the specific positions are not limited, and specifically, the positions shown in the preferred embodiment can be referred to; that is, as shown in Figures 5 and 6, the telescopic seats 27 are provided on both the left and right ends of the bottom plate 233.

[0046] Specifically, the second elastic member 273 preferably uses a spring, and as shown in FIG. 4, one end of the spring is attached to the base body 271 and the other end is attached to the end of the telescopic key 272 on the base body 271 side. For replacement and explanation of embodiments of the second elastic member 273, please refer to the first elastic member 263.

[0047] The following will provide a detailed description of the foldable frame 3 according to the utility model.

[0048] In this embodiment, the foldable frame 3 includes an articulated frame 32 including a push rod 321 and an interlocking rod 322, and further includes a fixed frame 31 for supporting the foldable basket 2 and a locking joint 33 for locking the interlocking rod 322. A linking device 35 is further provided, which is fitted to the fixed frame 31 and is used to fold the foldable frame 3 and the foldable basket 2 in an interlocked manner. The linking device 35 includes a second sliding seat 351 and an interlocking seat 352, and the second sliding seat 351 includes a stopper portion 3511 and a sliding portion 3512.

[0049] In this embodiment, the interlocking seat 352 is pivotally connected to the second sliding seat 351, and the number of interlocking seats 352 is set to at least two.

[0050] Specifically, in a preferred embodiment, in addition to the interlocking sheet 352 connected to the second sliding seat 351, another interlocking sheet 352 connected to the fixed frame 31 is provided, which further enhances the folding and stowing effect. More specifically, by making both ends of the interlocking sheet 352 hinge-connected, it is advantageous to enhance the smoothness of the folding process.

[0051] In this embodiment, as a preferred embodiment, the interlocking sheet 352 included in the interlocking device 35 is preferably provided with two interlocking sheets 352, namely, a first interlocking sheet 3521 and a second interlocking sheet 3522. The role of the interlocking sheet 352 is to further enhance the folding effect and make the folding process smoother. In practice, the number of interlocking sheets 352 can be increased according to objective needs.

[0052] In this embodiment, the joint frame 32 further includes hinge connection points 34 for connecting between the linking rods, and the linked rods 322 that are connected to each other can be folded around the hinge connection points 34. Furthermore, the joint frame 32 further includes hinge connection points 34 for connecting between the linking rods 322 and the linking sheet 352, and the linked rods 322 and the linking sheet 352 that are connected to each other can be folded around the hinge connection points 34.

[0053] Furthermore, this structure has five hinge connection points 34 for folding and stowing when folded. For details of the hinge connection points, please refer to the folding change diagrams in Figures 8 and 9. The description is as follows. 1. The first hinge connection point 341 is located at the connection position between the lock joint 33 and the first link 3221, and the first link 3221 is folded and stowing around the first hinge connection point 341. 2. The second hinge connection point 342 is located at the joint between the first link 3221 and the second link 3222. 3. The third hinge connection point 343 is located at the joint between the third link 3223 and the fourth link 3224. 4. The fourth hinge connection point 344 is located at the joint between the first link 3221 and the first interlocking sheet 352. 5. The fifth hinge connection point 345 is located at the connection point between the third link 3223 and the second interlocking sheet 3522. In summary, the foldable frame is folded by folding both the link structure and the interlocking sheet structure around the hinge connection point 34. When folding, see Figure 8, and Figure 9 shows the final folded state.

[0054] In this embodiment, the locking joint includes a port, and the linking rod is inserted into the port and locked via the locking joint. Specifically, in the second case, the linking rod is hinged to the port and locked via the locking joint.

[0055] In this embodiment, as a preferred embodiment, the locking joint 33 includes three ports: a first port 331, a second port 332, and a third port 333, and the joint frame 32 includes a push rod 321 and an interlocking rod 322. Specifically, the interlocking rod 322 includes four links: a first link 3221 and a second link 3222 that are connected as shown in Figures 7 to 9, and a third link 3223 and a fourth link 3224 that are similarly connected. Specifically, the push rod 321 is inserted into the first port 331 and connected to the locking joint 33, one end of the first link 3221 is inserted into the second port 332 and connected to the locking joint 33, the central part of the first link 3221 is connected to the second sliding seat 351 via the first interlocking seat 3521, and finally the other end of the first link 3221 is connected to the second link 3222, and the third link 3223 is connected to the locking joint 33 via the third port 333, the central part of the third link 3223 is connected to the fixed frame 31 via the second interlocking seat 3522, the other end of the third link 3223 is connected to the fourth link 3224, the end of the fourth link 3224 is connected to the cart tail 36 of the foldable frame 3, the cart tail 36 including a cart wheel 361 and a cart wheel rod 362. More specifically, one end of the second link 3222 is connected to the cart wheel rod 362, and this end serves as a rotation fulcrum, while the fourth link 3224 rotates around the connected cart wheel 361 as a fulcrum. For details, please refer to the folding movement state in Figures 8 and 9.

[0056] As can be understood, the opposite sides of the entire foldable frame 3 include structures such as equivalent joint frames, locking joints, hinge connection points, interlocking devices, etc., so only the specific structure of one side will be described, and when specifically assembling the parts on the opposite side, you can refer to the above structure description.

[0057] Here, the principle of the telescopic seat 27 will be explained in detail. When the foldable basket 2 is in a fixed state, the telescopic seat 27 is attached to the underside of the fixed frame 31 of the foldable frame 3. For specific details, refer to the states shown in Figures 1 to 3. When it is necessary to detach the foldable basket 2 from the fixed frame 31, the telescopic key 272 is pressed, and the telescopic key 272 enters the seat body 271 from the second elastic member 273, and from the abutting state, it is detached from the fixed frame 31, and the basket is removed from the foldable frame 3.

[0058] The linked folding of the foldable basket 2 and the foldable frame 3 includes the following technical points.

[0059] When the foldable basket 2 is engaged with the fixed frame 31, the second sliding seat 351 pushes up the hook portion 2621 of the locking hook 262 to unlock it from the first sliding seat 251. At this time, because the locking joint 33 is not unlocked, the foldable frame 3 remains engaged and the second sliding seat 351 cannot slide. The stopper portion 3511 of the second sliding seat 351 engages the first sliding seat 251, so the first sliding seat 251 cannot slide. When the foldable frame 3 is folded, the second sliding seat 351 slides to slide the first sliding seat 251, thereby realizing the simultaneous folding of the foldable basket 2 and the foldable frame 3.

[0060] However, it is necessary to further explain the technical points to prevent abnormal automatic retraction during the process of removing the foldable basket 2.

[0061] During the process of removing the foldable basket 2, the foldable basket 2 is lifted slightly, and the second sliding seat 351 has not yet disengaged from the groove of the first sliding seat 251. At this time, the locking hook 262 has already been re-locked with the first sliding seat 251 under the action of the first elastic member 263, so that the foldable basket 2 will not abnormally automatically fold.
