[0072] Reference below Figure 1-Figure 5 The foldable cart 100 according to the embodiment of the present invention is described in detail. The foldable cart is provided with foldable functional accessories on the cart body, realizing the integration of the functional accessories and the cart body, making the operation more convenient and convenient for storage and transportation.

[0073] A folding stroller 100 according to an embodiment of the present invention includes a body 10 and at least one functional accessory 20. The body 10 includes a frame 103, a handlebar 101 disposed in front of the frame 103, and wheels 102 fixed to the bottom of the frame. It is understood that the movement of the stroller 100 is controlled by coordinating the movement of the frame 103, handlebar 101, and wheels 102. The folding stroller 100 is unfolded from a folded state, ensuring that the frame 103 is fully unfolded and locked. The user controls the steering and provides pulling force via the handlebar 101. The functional accessory 20 is foldably mounted on the frame. The functional accessory has an unfolded state and a stowed state. In the stowed state, the functional accessory can be stacked on the rear, left, or right side of the frame. Specifically, foldable functional accessories can be provided on any direction of the rear, left and right sides of the frame. After folding, the functional accessories can be stored in a stacked posture on the rear, left or right side of the frame. The "stacked" here means that the functional accessories are placed on the frame in a parallel manner, that is, after the functional accessories 20 are applied to the cart with a bundle structure after storage provided by this embodiment, the cart 100 still maintains the storage form, so that it occupies a smaller space in the storage state, making it convenient to store the frame 103 in a limited space, solving the technical problem that the storage parts cannot be integrated with the cart 100 in the existing design, making it more convenient for consumers to operate, and convenient for storage and transportation.

[0074] Specifically, if Figure 2 and Figure 3As shown, the frame includes a folding chassis 1031, a front frame 1032 arranged in front of the folding chassis, a rear frame 1033 arranged behind the folding chassis, and folding side frames 1034, 1035 arranged on both sides of the folding chassis (i.e., the folding side frame 1034 on the left and the folding side frame 1035 on the right). In some examples, in the stowed state, the folding chassis 1031 and the folding side frames 1034 are folded together in the front-to-back direction, and the front frame 1032 and the rear frame 1033 are folded together in the left-to-right direction; in the unfolded state, the folding chassis 1031 and the folding side frames 1034, 1035 are flattened in the front-to-back direction, and the front frame 1032 and the rear frame 1033 are unfolded in the left-to-right direction. When the cart 100 provided by the present invention is used, when the cart 100 needs to be folded, When pushing the cart 100, force can be applied to the front frame 1032 and the rear frame 1033 respectively, so that the front frame 1032 and the rear frame 1033 are relatively close to each other, so that the folding side frames 1034 and 1035 are rotated and folded, and finally the folding side frames are brought together and the front frame 1032 and the rear frame 1033 are folded together, and the folding bottom frame 1031 is also brought together, so as to realize the folding of the cart 100. The cart 100 provided in this embodiment is in a bundle-like structure after folding, which is convenient for carrying and storage. When the cart 100 needs to be opened, it is only necessary to move the front frame 1032 and the rear frame 1033 relatively apart, and then rotate and flatten the folding side frames 1034 and 1035 in the front and rear directions, so as to realize the unfolding of the cart 100. In summary, when folding or opening the cart 100 provided by the utility model, it is only necessary to directly move the front frame 1032 and the rear frame 1033 relatively close to or away from each other, which is simpler and more convenient to operate, and saves trouble and effort. Figure 1-Figure 5 As shown, the vehicle body 10 has an expanded state and a stored state, and the user can convert the cart 100 to the expanded state or the stored state according to actual needs.

[0075] like Figure 1-Figure 5As shown, in some preferred embodiments, the functional accessory 20 can be folded and arranged on the rear frame. Specifically, regardless of whether the functional accessory 20 is folded or not, the functional accessory 20 is arranged on the rear frame 1033. Compared with the storage parts provided by the prior art that are designed to be separated from the vehicle body 10, the functional accessory 20 provided in this embodiment is integrated with the rear frame 1033, which solves the technical problems of large packaging quantities and inconvenient storage and transportation caused by the separate arrangement of other functional accessories such as storage parts and the cart 100, and is more convenient for the operator to use and store. Furthermore, when the functional accessory 20 has an expanded state and a stored state, the user can convert the functional accessory 20 to the expanded state or the stored state according to actual needs. When in the expanded state, the functional accessory 20 can play its intended function, such as being used as a storage, workbench, and other functions; when in the stored state, the functional accessory 20 can be stacked on the rear frame, and the cart 100 still maintains the stored form, so that it occupies a smaller space in the stored state, making it convenient to store the frame 103 in a limited space, solving the technical problem that the storage parts in the existing design cannot be integrated with the cart 100, making it more convenient for consumers to operate, and convenient for storage and transportation.

[0076] The cart 100 provided by the present invention integrates the functional accessories 20 with the body 10 and folds them onto the rear frame 1033 in a stacked manner rather than vertically or at other angles. This not only solves the problem of separate functional accessories in traditional carts, but also provides a better user experience and convenience. The folding cart of the present invention not only reduces the amount of packaging and storage and transportation difficulties, but also offers the advantages of easy operation, storage, and portability. Therefore, this folding cart 100 is suitable for a variety of scenarios requiring the storage and transportation of items.

[0077] See also Figure 1-Figure 5 In some embodiments, one end of the functional accessory 20 is movably connected to the rear frame 1033, and the other end is detachably connected to the rear frame 1033. Specifically, the user can change the state of the functional accessory 20 according to usage needs. When the functional accessory 20 is required to be in an expanded state, one end of the functional accessory 20 is movably connected to the rear frame 1033, and the other end is connected to the rear frame 1033. In this way, the functional accessory 20 remains in the expanded state for carrying items or other uses. The end of the functional accessory 20 that is movably connected to the rear frame 1033 cannot rotate within a limited range due to the fixed connection of the other end. When the functional accessory 20 needs to be folded, the other end of the functional accessory 20 is removed from the rear frame 1033. At this time, the functional accessory 20 is rotated to a position parallel to the rear frame 1033 using the movable end of the functional accessory 20, that is, it is folded on the rear frame 1033 in a stacked manner, thereby reducing the storage space required for the functional accessory 20 in the folded state.

[0078] Preferably, see Figure 2 and Figure 3 The cart also includes a rotating connector 30, which is suitable for being rotatably connected to the rear frame 1033 along a first axis a, and the functional accessory 20 is suitable for being rotatably connected to the rotating connector 30 around a second axis b. The first axis a extends in the up-down direction, and the second axis b extends in the front-back direction. Specifically, the first axis a extends along the up and down direction of the cart, and the second axis b extends along the front and back direction. The functional accessory 20 is rotatably connected to the rotating connector 30 so as to be able to rotate around the second axis b, and the rotating connector 30 itself is rotatably connected to the rear frame 1033 and can rotate around the first axis a. That is, the functional accessory 20 provided in this embodiment is able to rotate on both the first axis a and the second axis b through the mutual rotation cooperation between the rotating connector 30 and the rear frame 1033. In this way, when the functional accessory 20 is in the unfolded state, the functional accessory 20 is unfolded in a form parallel to the base frame. When it needs to be folded, it first needs to be flipped downward around the second axis, and then it is flipped toward the rear frame 1033 around the first axis a to achieve bundle folding.

[0079] Furthermore, the cart further includes a connector 40 disposed on the rear frame 1033. The connector 40 is rotatably connected to the rotating connector 30 so that the rotating connector 30 can rotate about the first axis a. Specifically, the rear side of the rear frame 1033 is rotatably engaged with the connector 40 and the rotating connector 30, and the rotation axes of the connector 40 and the rotating connector 30 extend vertically along the first axis a.

[0080] In some embodiments, the functional accessory 20 is connected to the rear frame 1033 via a buckle 50 or screws, either of which allows for a detachable connection. Preferably, the rear frame 1033 is provided with a buckle 501, and the functional accessory 20 is provided with a slot 502 adapted for the buckle. The handheld storage platform 20 is lifted upward until the slot 502 disengages the buckle 501. As the slot 502 and the buckle 501 become displaced, the storage platform 20 folds downward about the second axis b to a position parallel to the side frames 1034 and 1035. The storage platform 20 is then horizontally flipped about the first axis a to a position parallel to the rear frame 1033, completing the folding process. Simultaneously, the locking member of the cart is pulled upward to fold the cart into a bundle. Exemplarily, the buckle 501 is a square washer. It is understandable that, in some examples, the rear frame 1033 is provided with a card slot, and the functional accessories are provided with a buckle adapted to the card slot. This structure can also enable the storage table 20 to be detachable.

[0081] In some examples, the functional accessories 20 include but are not limited to a storage table, a storage box or a storage bag. In this embodiment, please refer to Figure 4 and Figure 5 The functional accessory is a storage table, and a cup holder 201 is also provided on the storage table. Specifically, the storage table can be used as an operating table, a desktop, a storage table, etc. Specifically, the storage table is generally a flat structure, which is easier to stack and fold than other structures.

[0082] Specifically, the rotating connection member includes a rotating shaft 301 and a pivot seat 302. The rotating shaft 301 is connected to the pivot seat 302, and the rotating shaft 301 extends along the second axis b. The rotating shaft 301 is rotatably connected to the storage platform 20, and the pivot seat 302 is rotatably connected to the rear frame 1033. Specifically, the pivot seat 302 is rotatably connected to the connecting member 40 of the rear frame 1033. It can be understood that the rotating shaft 301 and the storage platform 20 are rotatably engaged to ensure that the storage platform 20 can be folded downward about the second axis b. The rotating shaft 301 is rotatably connected to the storage platform 20, and the pivot seat 302 is rotatably engaged with the connecting member 40 of the rear frame 1033 to ensure that the pivot seat 302 rotates about the first axis a. The rotating shaft 301 is rotatably engaged with the storage table 20. In this embodiment, a sleeve 202 is provided on the bottom side of the storage table 20, and the rotating shaft 301 is rotatably provided in the sleeve 202. In other embodiments, a rotating shaft is provided on the bottom side of the storage table, and the rotating shaft 301 is in the form of a sleeve. The rotating shaft on the bottom side of the storage table can be rotatably engaged in the rotating shaft 301, which can also realize the rotation of the storage table around the second axis.

[0083] Furthermore, the cart further includes a rotation limiting device 60, which is disposed between the sleeve 202 and the rotating shaft 301 to limit the rotation angle of the storage platform 20. Specifically, when a user folds the storage platform 20 downward 90° from a horizontal position to a vertical position, i.e., switches from the expanded state to the folded state, to avoid uncontrollable operational issues such as excessive flipping caused by the storage platform's 360° rotation, this embodiment provides a rotation limiting device 60 to limit the rotation angle of the storage platform 20. Specifically, the rotation limiting device 60 includes a limiting groove 601 disposed on the sleeve 202 and a limiting block 602 disposed on the rotating shaft. The limiting groove 601 is formed as an arc-shaped groove disposed around the second axis, and the limiting block 602 is slidably engaged within the limiting groove 601. The limiting groove 601 and the limiting block 602 cooperate to control the rotation angle of the storage platform to 90°, i.e., switch from the horizontal position to the vertical position, making the operation more controllable.

[0084] Furthermore, when the storage platform 20 is in a vertical position perpendicular to the rear frame, if the storage platform 20 rotates 360° relative to the rotation axis 301, the user can only operate the pivot seat 302 to drive the storage platform 20 to a vertical position parallel to the rear frame 1033. It is impossible to directly drive the storage platform 20 to fold it, which is extremely inconvenient. Therefore, with the help of the rotation limiter 60, the storage platform 20 is restrained by the rotation axis 301 after being flipped about the second axis b to the vertical position. At this time, to proceed with the second step of stacking and folding, the user can directly push the storage platform 20 to complete the flipping of the storage platform 20 from the vertical position perpendicular to the rear frame 1033 to the vertical position parallel to the rear frame 1033.

[0085] In some examples, such as Figure 1 As shown, the rear frame 1033 includes a left strut 104 and a right strut 105, an upper left connecting head 106 and a lower left connecting head 107, an upper right connecting head 108 and a lower right connecting head 109 and a cross-link assembly 110. The left strut 104 and the right strut 105 are symmetrically arranged on the left and right sides. The upper left connecting head 106 and the lower left connecting head 107 are respectively connected to the upper end and the lower end of the left strut 104, the upper right connecting head 108 and the lower right connecting head 109 are respectively connected to the upper end and the lower end of the right strut 105, and the cross-link assembly 110 is connected between the upper left connecting head 106, the lower left connecting head 107, the upper right connecting head 108 and the lower right connecting head 109 so that the left strut 104 and the right strut 105 can be folded along the left and right directions. It can be understood that the folding base frame 1031 and folding side frames 1034, 1035 provided in this embodiment can refer to the folding cart disclosed in CN201712643U. The folding base frame, folding side frames, front frame and rear frame all rely on cross-link assemblies to achieve folding, realizing bundle-type folding. In order to further reduce the impact of the storage platform on the storage volume of the cart, the length and width of the storage platform provided in this embodiment do not exceed the length and width of the rear frame of the vehicle body after folding.

[0086] Furthermore, a buckle 501 is provided on the rear side of the upper left connecting head 106, and the storage platform 20 is provided with a slot 502 that cooperates with the buckle limiter. A connecting member 40 is provided on the rear side of the upper right connecting head 108, and the connecting member 40 is rotatably connected to the pivot seat 302. That is, in addition to the installation function of the cross-link assembly, the upper left connecting head 106 and the upper right connecting head 108 are also used for the installation of functional accessories, connecting members and detachable structures, which does not have any adverse effects on the folding function of the rear frame, and the storage space is significantly increased, the application of the cart is more extensive and the function is increased.

[0087] Specifically, the rotating connector can be made of hardware, plastic or other materials; the connector can be made of metal, plastic or other materials.

[0088] The cart provided in this embodiment has the following working process:

[0089] See also Figure 1 When the storage table is opened, the slot 502 on the left side of the storage table 20 is slidably connected with the buckle 501 on the rear side of the upper left connector 106 of the rear frame of the cart. After the slot 502 and the buckle 501 are buckled together, the movement of the movable end of the storage table is restricted, so that the storage table 20 can be fixed on the cart when in use, and the storage table completes the function of carrying items.

[0090] See also Figure 2-Figure 5 To fold the storage platform, the platform 20 is lifted upward until the slot 502 disengages the latch 501. As the slot 502 and the latch 501 disengage, the platform 20 folds downward about the second axis b. Simultaneously, the stopper 602 rotates in an arc along the stopper slot 601 until it stops at a predetermined position. At this point, the platform remains in a vertical position perpendicular to the rear frame. Finally, the platform 20 is flipped horizontally about the first axis a to a vertical position parallel to the rear frame. The platform 20 is folded, and the locking member of the cart is pulled upward to fold the cart into a bundle.
