Description

Technical Field

[0001] This invention relates to the field of basket technology, and in particular to a basket that can be folded and operated with one hand. Background Technology

[0002] Existing folding baskets generally include two side frames and a bottom frame. The side frames are usually folded by rotating through a central joint, while the bottom frames are folded by rotating through a pivot. The corresponding side frames and bottom frames are linked by support rods so that the bottom frame moves with the frame.

[0003] However, the existing structure still has the following shortcomings in actual use: the linkage between the frame and the base is relatively simple, and the support rods usually only play a one-way pushing and pulling role. During the process of the frame flipping and folding upward, the support rods are difficult to drive the base to complete the folding action in a synchronous and smooth manner. It is easy for the frame to be folded into place but the base is not fully closed. Users need to manually press the base to complete the final folding, which is not convenient or smooth enough.

[0004] Meanwhile, the front and rear base frames lack an independent linkage transmission mechanism. In the existing structure, the front and rear base frames are each hinged to the base frame connecting seat through separate pivots. There is no direct motion transmission relationship between the two, which means that the front and rear base frames cannot be synchronously retracted when folding. Often, one side is retracted while the other side is still outward, which not only affects the folding efficiency but also makes the overall structure after folding less regular and compact.

[0005] In addition, the intermediate joints usually maintain a relatively fixed position relative to the base frame connector when locked. During the frame flipping and folding process, the intermediate joints cannot be adjusted in the vertical direction relative to the base frame connector, resulting in an overall structure that is not compact after folding, and a large volume after folding, which is inconvenient for subsequent handling and storage.

[0006] Furthermore, the folding basket exhibits poor structural stability when unfolded. Specifically, when the basket is unfolded, if downward pressure or upward pull is applied to the front or rear of the basket, the upper frame is prone to tilting forward or backward relative to the base frame due to the lack of an effective front and rear limiting structure.

[0007] Therefore, this invention addresses the aforementioned problems. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a basket that can be folded and retracted with one hand. The frame assembly and base frame assembly are interconnected through a front linkage component, a base frame linkage component, and a rear linkage component, allowing the base frame assembly to fold and retract in tandem with the frame assembly, forming a coordinated folding and retracting mechanism. Specifically, during the upward flipping of the front frame, the front linkage component drives the front base frame to flip upward synchronously to fold towards the front frame; the front base frame, through the base frame linkage component, drives the rear base frame to fold towards each other synchronously; and the rear base frame pushes the rear frame upward in tandem to fold towards the front frame. This allows the frame assembly and base frame assembly to complete folding simultaneously in a single operation, eliminating the need for step-by-step operations or additional manual intervention. This enables the basket to be folded and retracted entirely with one hand, featuring smooth folding and high efficiency. The folded basket has a compact overall structure, facilitating subsequent carrying and storage. Furthermore, the single-handed folding capability meets the user's need for quick storage, significantly improving ease of use.

[0009] To solve the above-mentioned technical problems, the present invention provides a basket that can be folded and unfolded with one hand, having an unfolded use state and a folded use state, including:

[0010] The frame assembly 1 includes a front frame 11 and a rear frame 12 that can be folded in opposite directions or unfolded in opposite directions. The front frame 11 and the rear frame 12 are rotatably connected by a frame joint 13, which is configured to lock the frame assembly 1 in an unfolded use state.

[0011] A frame unlocking mechanism 14 is provided on the frame component 1 and is linked to the frame joint 13.

[0012] The base frame assembly 2 is located below the frame assembly 1. The base frame assembly 2 includes a front base frame 21, a base frame connecting seat 22, a rear base frame 23, and a base frame linkage 24. The front side of the base frame connecting seat 22 is rotatably connected to the front base frame 21 about pivot A, and the rear side of the base frame connecting seat 22 is rotatably connected to the rear base frame 23 about pivot B. The front end of the base frame linkage 24 is rotatably connected to the front base frame 21 about pivot C, which is offset from pivot A, and the rear end of the base frame linkage 24 is rotatably connected to the rear base frame 23 about pivot D, which is offset from pivot B. The base frame linkage 24 is configured such that when the front frame 11 is unlocked relative to the rear frame 12 and flips upward, the front base frame 21 is linked by the base frame linkage 24 to fold the rear base frame 23 towards each other synchronously.

[0013] The front linkage component 3 is movably connected to the front frame 11 at its upper end and to the front base frame 21 at its lower end. The front linkage component 3 is configured to drive the front base frame 21 to rotate upward synchronously during the upward rotation of the front frame 11 so as to fold towards the front frame 11.

[0014] The rear linkage component 4 is movably connected to the rear frame 12 at its upper end and to the rear base frame 23 at its lower end. The rear linkage component 4 is configured to push the rear frame 12 to rotate upward in coordination with the rear base frame 23 during the upward rotation process, so as to fold and move towards the front frame 11.

[0015] The retraction and extension guide component 5 is located between the frame joint 13 and the base frame connecting seat 22, and is used to guide the frame joint 13 to move up and down relative to the base frame connecting seat 22 during the retraction and extension actions.

[0016] As described above, in the case of a basket that can be folded and unfolded with one hand, when the basket is in the unfolded state, the distance between the pivot of the frame joint 13 and the base frame connecting seat 22 is L1; when the basket is in the folded state, the distance between the pivot of the frame joint 13 and the base frame connecting seat 22 is L2, and L2 < L1.

[0017] As described above, a basket that can be folded and unfolded with one hand includes a folding and unfolding guide assembly 5 comprising a folding and unfolding connecting seat 51 and a folding and unfolding guide rod 52.

The lower end of the folding and unfolding guide rod 52 is relatively fixedly connected to the base frame connecting seat 22. The folding and unfolding guide rod 52 is slidably inserted into the folding and unfolding guide hole 511. When the basket switches between the unfolded and folded use states, the folding and unfolding connecting seat 51 slides along the length direction of the folding and unfolding guide rod 52, thereby causing the frame joint 13 to slide downward or upward relative to the base frame connecting seat 22 accordingly.

[0018] As described above, a basket that can be folded and unfolded with one hand has a blocking and limiting groove 512 on the unfolding and unfolding connecting seat 51 that communicates with the upper port of the unfolding and unfolding guide hole 511, and a blocking and limiting protrusion 521 on the upper end of the unfolding and unfolding guide rod 52 that is used to block and limit the basket when it is in the unfolded state.

[0019] As described above, a basket that can be folded and unfolded with one hand has a blocking and limiting groove 512 with a front blocking wall 513 and a rear blocking wall 514. When the basket is in the unfolded state, the front side wall of the blocking and limiting protrusion 521 engages with the front blocking wall 513 and the rear side wall of the blocking and limiting protrusion 521 engages with the rear blocking wall 514 to limit the back-and-forth movement of the unfolding connecting seat 51 and the frame joint 13 relative to the unfolding guide rod 52.

[0031] Compared with the prior art, the present invention has the following advantages:

[0032] 1. In this invention, the frame assembly and the base frame assembly are linked by a front linkage assembly, a base frame linkage component, and a rear linkage assembly, enabling the base frame assembly to retract and expand accordingly with the retraction and expansion of the frame assembly, forming a set of coordinated retraction and expansion mechanisms. Specifically, during the upward flipping of the front frame, the front linkage assembly drives the front base frame to flip upward synchronously to fold towards the front frame; the front base frame, through the base frame linkage component, drives the rear base frame to fold towards each other synchronously; and the rear base frame pushes the rear frame to flip upward in coordination with the front frame to fold towards each other. This allows the frame assembly and the base frame assembly to complete the retraction and expansion synchronously in a single operation, without the need for step-by-step operations or additional manual intervention. It enables the basket to be folded as a whole with one hand, featuring smooth folding and high efficiency. The overall structure is compact after folding, making it convenient for subsequent carrying and storage. Furthermore, it enables one-handed folding, meeting the user's need for quick storage and significantly improving ease of use.

[0033] 2. The present invention provides a clear up-and-down movement trajectory for the folding and unfolding process of the basket through the folding and unfolding guide component; specifically, when the frame component is flipped and folded, the frame joint can move smoothly down relative to the base frame connecting seat along the folding and unfolding guide component, and the folding and unfolding is smooth; when unfolding, the folding and unfolding guide component can guide the frame joint to accurately reset, ensuring that the frame joint smoothly reaches the locking position and ensuring structural stability.

[0034] 3. The present invention uses the blocking and limiting protrusion and the blocking and limiting groove to block and limit, which makes it easy for users to know whether the basket has been unfolded in place and facilitates the subsequent alignment and locking of the frame joints. At the same time, it can also increase the blocking and limiting area between the unfolding guide rod and the unfolding connecting seat, thereby improving the structural stability and reliability of the two.

[0035] 4. When the basket is in the unfolded state, the front side wall of the blocking and limiting protrusion cooperates with the front blocking wall, and the rear side wall of the blocking and limiting protrusion cooperates with the rear blocking wall to limit the forward and backward swaying of the unfolding connecting seat and the frame joint relative to the unfolding guide rod. This can effectively prevent the frame assembly from tilting forward or backward relative to the base frame assembly. At the same time, it can also indirectly strengthen the stress strength of the frame joint when unfolded, making the overall structure of the basket more stable and reliable, and greatly improving the safety of the product.

[0036] 5. In order to constrain the front frame and the front base frame, as well as the rear frame and the rear base frame, and to ensure stable movement trajectory during the upward and downward closing or opening process, the front linkage component is connected to the front frame and the front base frame to form a parallel four-bar linkage mechanism, and the rear linkage component is connected to the rear frame and the rear base frame to form a parallel four-bar linkage mechanism. That is, the parallel four-bar linkage mechanism makes the basket move smoothly and steadily during the upward and downward closing and opening process.

[0037] 6. To facilitate one-handed unlocking, the frame unlocking mechanism is configured to respond to a one-handed triggering operation by linking the unlocking action of the frame joints on both sides of the frame component. Attached Figure Description

[0055] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0056] like Figure 1-16As shown, the present invention discloses a basket that can be folded and unfolded with one hand, having an unfolded and folded usage state. It includes a frame assembly 1, a frame unlocking mechanism 14, a base frame assembly 2, a front linkage assembly 3, a rear linkage assembly 4, and an unfolding / folding guide assembly 5. The frame assembly 1 includes a front frame 11 and a rear frame 12 that can be folded in opposite directions or unfolded in opposite directions. The front frame 11 and the rear frame 12 are rotatably connected by a frame joint 13, which is configured to lock the frame assembly 1 in the unfolded usage state. The frame unlocking mechanism 14 is used to lock the frame assembly 1 in the unfolded usage state. The locking mechanism 14 is mounted on the frame assembly 1 and is linked with the frame joint 13; the base frame assembly 2 is located below the frame assembly 1, and the base frame assembly 2 includes a front base frame 21, a base frame connecting seat 22, a rear base frame 23, and a base frame linkage 24. The front side of the base frame connecting seat 22 is rotatably connected to the front base frame 21 about pivot A, and the rear side of the base frame connecting seat 22 is rotatably connected to the rear base frame 23 about pivot B. The front end of the base frame linkage 24 is rotatably connected to the front base frame 21 about pivot C, which is offset from pivot A. 4. The rear end and the rear base frame 23 are rotatably connected about a pivot D offset from pivot B. The base frame linkage 24 is configured such that when the front frame 11 is unlocked relative to the rear frame 12 and flips upward, the front base frame 21, through the base frame linkage 24, links the rear base frame 23 to fold towards each other synchronously. The upper end of the front linkage assembly 3 is movably connected to the front frame 11, and the lower end of the front linkage assembly 3 is movably connected to the front base frame 21. The front linkage assembly 3 is configured to drive the front base frame 21 to move upward synchronously during the upward flipping of the front frame 11. The frame is flipped to fold towards the front frame 11; the upper end of the rear linkage component 4 is movably connected to the rear frame 12, and the lower end of the rear linkage component 4 is movably connected to the rear base frame 23. The rear linkage component 4 is configured to push the rear frame 12 to flip upward in coordination with the rear base frame 23 during the upward flipping process, so as to fold towards the front frame 11; the retraction and extension guide component 5 is located between the frame joint 13 and the base frame connecting seat 22, and is used to guide the frame joint 13 to move up and down relative to the base frame connecting seat 22 during the retraction and extension actions. The frame assembly and the base frame assembly are linked by a front linkage component, a base frame linkage component, and a rear linkage component, allowing the base frame assembly to retract and expand in tandem with the frame assembly, forming a coordinated retraction and expansion mechanism. Specifically, during the upward flipping of the front frame, the front linkage component drives the front base frame to flip upward synchronously to fold towards the front frame; the front base frame, through the base frame linkage component, drives the rear base frame to fold towards each other synchronously; and the rear base frame pushes the rear frame to flip upward in tandem with the front frame, folding towards each other. This allows the frame assembly and the base frame assembly to complete the retraction and expansion simultaneously in a single operation, without the need for step-by-step operations or additional manual intervention. It enables the basket to be folded as a whole with one hand, featuring smooth folding and high efficiency. The overall structure is compact after folding, making it convenient for subsequent carrying and storage. Furthermore, it allows for one-handed folding, meeting the user's need for quick storage and significantly improving ease of use.

[0057] The folding and unfolding guide assembly provides a clear up-and-down movement trajectory for the folding and unfolding process of the basket. Specifically, when the frame assembly is flipped and folded, the frame joints can move smoothly down relative to the base frame connecting seat along the folding and unfolding guide assembly, resulting in smooth folding. When unfolding, the folding and unfolding guide assembly can guide the frame joints to accurately reset, ensuring that the frame joints smoothly reach the locking position and ensuring structural stability.

[0058] This invention provides a basket that can be used as a children's basket, a shopping basket, and a pet basket, achieving multiple uses in one product. When the basket is attached to a stroller frame, it can be used as a children's stroller, a shopping stroller, or a pet stroller.

[0059] like Figure 1-4 As shown, when the basket is in the unfolded state, the distance between the pivot shaft of the frame joint 13 and the base frame connecting seat 22 is L1; when the basket is in the folded state, the distance between the pivot shaft of the frame joint 13 and the base frame connecting seat 22 is L2, and L2 < L1. This allows the frame assembly to move lower and closer to the base frame assembly during the folding process, providing greater seating height and stable support when unfolded, and further compressing the overall height and making the folded volume smaller when folded. At the same time, this distance change is guided by the unfolding guide assembly and matches the movement of the front and rear linkage components, avoiding interference and jamming. Only one unlocking operation is needed to complete the linkage folding, making the structure reliable and easy to operate.

[0060] like Figure 1-5 As shown, for stable and smooth folding and unfolding, the folding and unfolding guide assembly 5 includes a folding and unfolding connecting seat 51 and a folding and unfolding guide rod 52. The folding and unfolding connecting seat 51 is rotatably connected to the frame joint 13. The folding and unfolding connecting seat 51 is provided with a folding and unfolding guide hole 511. The lower end of the folding and unfolding guide rod 52 is relatively fixedly connected to the base frame connecting seat 22. The folding and unfolding guide rod 52 is slidably inserted into the folding and unfolding guide hole 511. When the basket switches between the unfolded and folded use states, the folding and unfolding connecting seat 51 slides along the length direction of the folding and unfolding guide rod 52, thereby causing the frame joint 13 to slide downward or upward relative to the base frame connecting seat 22 accordingly. On the one hand, the folding and unfolding guide assembly 5 ensures that the frame assembly rises and falls smoothly relative to the base frame assembly by axially limiting the folding and unfolding guide rod 52, so that the frame assembly moves downward to compress the overall height when folded and moves upward to obtain more seating space when unfolded, and the folding and unfolding process is smooth and does not jam. On the other hand, the rotational cooperation between the folding and unfolding connecting seat and the frame joint avoids interference when multiple linkages are linked.

[0061] In this embodiment, the retractable guide rod 52 is made of a rigid material, such as iron, to ensure its structural strength. The lower end of the retractable guide rod 52 is fixed to the base frame connecting seat by means of screws, rivets, etc.

[0062] like Figure 1-9 As shown, the retractable connecting seat 51 is provided with a blocking and limiting groove 512 communicating with the upper port of the retractable guide hole 511. The upper end of the retractable guide rod 52 is provided with a blocking and limiting protrusion 521, which is used to block and limit the basket when it is in the retracted state. In this embodiment, the blocking and limiting protrusion and the blocking and limiting groove cooperate to block and limit the basket, which makes it easy for the user to know whether the basket is fully retracted and facilitates the subsequent alignment and locking of the frame joints. At the same time, it can also increase the blocking and limiting area between the retractable guide rod and the retractable connecting seat, thereby improving the structural stability and reliability of the two.

[0063] like Figure 1-9 As shown, the blocking and limiting groove 512 has a front blocking wall 513 and a rear blocking wall 514. When the basket is in the unfolded state, the front side wall of the blocking and limiting protrusion 521 engages with the front blocking wall 513, and the rear side wall of the blocking and limiting protrusion 521 engages with the rear blocking wall 514 to limit the forward and backward swaying of the retractable connecting seat 51 and the frame joint 13 relative to the retractable guide rod 52. This effectively prevents the frame assembly from tilting forward or backward relative to the base frame assembly. It also indirectly strengthens the frame joint's stress resistance during unfolding, making the overall structure of the basket more stable and reliable, and greatly improving the product's safety. The front blocking wall 513 and the rear blocking wall 514 can also be formed from the corresponding side walls of the retractable guide hole 511.

[0064] like Figure 1 , 2 As shown in Figures 3 and 5, when the basket is in the unfolded state, the lower surface of the blocking and limiting protrusion 521 and the inner bottom wall of the blocking and limiting groove 512 cooperate to restrict the upward freedom of the frame joint. The front side wall of the blocking and limiting protrusion 521 cooperates with the front blocking wall 513, and the rear side wall of the blocking and limiting protrusion 521 cooperates with the rear blocking wall 514 to restrict the front and rear freedom of the frame joint. At the same time, the downward freedom of the frame joint is restricted by the front linkage component and the rear linkage component, thus ensuring that the basket as a whole will not shake.

[0065] In addition, the lower surface of the blocking and limiting protrusion 521 is blocked and limited by the bottom wall of the blocking and limiting groove 512. Therefore, when unlocking and folding, the folding and unfolding connecting seat 51 can only slide downward, making the unlocking direction of folding unique. When the basket is unfolded, the upward freedom of the folding and unfolding connecting seat 51 relative to the folding and unfolding guide rod 52 is restricted.

[0066] like Figure 5As shown, the bottom wall of the blocking and limiting groove 512 is inclined, and the lower surface of the blocking and limiting protrusion 521 is inclined. When the basket is in the unfolded state, the blocking and limiting protrusion slides into the blocking and limiting groove and the two inclined surfaces fit together. The inclined surfaces generate a downward pressing force during the upward movement of the frame assembly relative to the base frame assembly, which tightens the frame joint relative to the base frame connecting seat to eliminate the unfolding gap, improve the overall rigidity and locking reliability. At the same time, the inclined surfaces have a self-centering guiding function, which makes it easy for the blocking and limiting protrusion 521 to be smoothly embedded into the blocking and limiting groove 512.

[0067] like Figure 1-3 As shown, to constrain the front frame and front base frame, and the rear frame and rear base frame, and to ensure stable movement during the upward and downward closing or unfolding process, the upper end of the front linkage component 3 is rotatably connected to the front frame 11, and the lower end of the front linkage component 3 is rotatably connected to the front base frame 21. When the basket is in the unfolded state, the front linkage component 3, the front frame 11, and the front base frame 21 form a parallel four-bar linkage mechanism. And / or, the upper end of the rear linkage component 4 is rotatably connected to the rear frame 12, and the lower end of the rear linkage component 4 is rotatably connected to the rear base frame 23. When the basket is in the unfolded state, the rear linkage component 4, the rear frame 12, and the rear base frame 23 form a parallel four-bar linkage mechanism. That is, the parallel four-bar linkage mechanism ensures smooth and stable upward and downward closing and unfolding movements of the basket during the opening and closing process.

[0068] like Figure 1-3 As shown, in order to constrain the movement trajectory of the base frame assembly and the frame assembly and ensure smooth and stable opening and closing of the basket, the front linkage assembly 3 includes a front connecting rod 31 and a front connecting rod 32 arranged in parallel with each other. The upper ends of the front connecting rod 31 and the front connecting rod 32 are rotatably connected to the front frame 11, and the lower ends of the front connecting rod 31 and the front connecting rod 32 are rotatably connected to the front base frame 21, respectively. And / or, the rear linkage assembly 4 includes a rear connecting rod 41 and a rear connecting rod 42 arranged in parallel with each other. The upper ends of the rear connecting rod 41 and the rear connecting rod 42 are rotatably connected to the rear frame 12, respectively, and the lower ends of the rear connecting rod 41 and the rear connecting rod 42 are rotatably connected to the rear base frame 23, respectively.

[0069] like Figure 3 As shown, in order to provide more stable and reliable support, both the first front link 31 and the second front link 32 are inclined outward from bottom to top, and the angle α between the first front link 31 and the second front link 32 and the front base frame 21 is an acute angle; the first rear link 41 and the second rear link 42 are inclined outward from bottom to top, and the angle β between the first rear link 41 and the second rear link 42 and the rear base frame 23 is an acute angle.

[0070] like Figure 1-3As shown, in order to facilitate disassembly and assembly and ensure stable and reliable connection, the upper surface of the base frame assembly 2 is provided with snap-fit ​​parts 20 at the front and rear. Each snap-fit ​​part 20 is provided with a snap-fit ​​recess 201 for the lower end of the front linkage assembly and the rear linkage assembly to snap into and position, so that the multiple snap-fit ​​parts on the base frame assembly bear the force evenly and transmit it to the snap-fit ​​parts.

[0071] like Figure 10-12 As shown, in order to achieve one-handed unlocking, the frame unlocking mechanism 14 is configured to respond to a one-handed triggering operation to link the unlocking action of the frame joints 13 on both sides of the frame assembly 1. The frame unlocking mechanism 14 is provided on the front frame 11 and includes a frame unlocking plate buckle 141 rotatably connected to the front frame 11 at its upper end, a frame unlocking linkage member 142 provided on the front frame 11, and a frame unlocking rotating seat 143 rotatably provided in the frame joint 13. One end of the frame unlocking linkage member 142 is connected to the frame unlocking plate buckle 141, and the other end of the frame unlocking linkage member 142 is connected to the corresponding frame unlocking rotating seat 143. The frame unlocking rotating seat 143 is linked with the frame joint 13, and a frame unlocking elastic member 144 is provided between the frame unlocking rotating seat 143 and the frame joint 13 for driving the frame unlocking rotating seat 143 to rotate and reset.

[0072] like Figure 10-12 As shown, in order to unlock smoothly, a rotation guide assembly 145 is provided between the frame unlocking rotating seat 143 and the front joint block 131. The rotation guide assembly 145 includes, but is not limited to, a rotation guide protrusion 1451 and a rotation guide arc groove 1452 that are provided between the frame unlocking rotating seat 143 and the front joint block 131 and can be guided and engaged.

[0073] like Figure 10-12 As shown, to prevent misoperation and ensure safe use, a safety blocking component 15 is provided between the frame unlocking plate buckle 141 and the front frame 11. The safety blocking component 15 includes a safety blocking part 151 provided on the front frame 11 and a safety blocking block 152 slidably provided on the frame unlocking plate buckle 141 and cooperating with the safety blocking part 151. A safety blocking elastic member 153 is provided between the safety blocking block 152 and the safety unlocking plate buckle to drive the safety blocking block 152 to elastically reset.

[0074] like Figure 8 , 9As shown, for reliable locking, the frame joint 13 includes a front joint block 131 fixedly connected to the front frame 11 and a rear joint block 132 fixedly connected to the rear frame 12 and rotatably connected to the front joint block 131; the frame joint 13 also includes frame locking tooth grooves 133 evenly provided on the front joint block 131 and the rear joint block 132, and a frame locking tooth block 134 slidably provided between the front joint block 131 and the rear joint block 132 and capable of simultaneously engaging with the frame locking tooth grooves 133 on the front joint block 131 and the rear joint block 132; the frame locking tooth block 134 is linked with the frame unlocking rotating seat 143.

[0075] like Figure 8 , 9 As shown, in order to ensure smooth unlocking and a compact structure, the frame locking tooth block 134 and the frame unlocking rotating seat 143 are engaged by two mutually unlocking inclined surfaces 1431. When unlocking, the user presses the safety block 152 to retract relative to the frame unlocking plate buckle 141, thus separating it from the safety block 151. Then, the user operates the frame unlocking plate buckle 141 to flip upward relative to the front frame. The frame unlocking plate buckle 141 drives the frame unlocking rotating seat 143 to rotate relative to the front joint block 131 through the frame unlocking linkage 142. The frame unlocking rotating seat 143 drives the frame locking tooth block 134 to slide accordingly through the two unlocking engagement frame unlocking inclined surfaces 1431 until the frame locking tooth block 134 separates from the frame locking tooth groove 133 on the rear joint block 132, thereby releasing the locking state between the front joint block 131 and the rear joint block 132. Then, the user operates the frame unlocking plate buckle 141 to drive the front frame to flip upward and fold. The front frame directly or indirectly drives the base frame assembly and the rear frame to flip and fold directly through the front linkage assembly, the base frame linkage assembly and the rear linkage assembly, thus realizing the linkage folding operation of the entire basket, enabling one-handed folding, meeting the user's need for quick storage and significantly improving ease of use.

[0076] like Figure 1-4As shown in Figures 13-16, for ease of assembly, a basket adapter 6 is rotatably provided on the base frame connecting seat 22 for detachable connection with the frame connector. A base frame locking component 61 is provided between the basket adapter 6 and the base frame connecting seat 22 to lock the base frame connecting seat 22 relative to the basket adapter 6. A base frame unlocking mechanism 62 is provided between the base frame connecting seat 22 and the basket adapter 6 to be linked with the base frame locking component 61. The base frame unlocking mechanism 62 is configured to be linked with the base frame assembly 2 during folding, thereby causing the base frame unlocking mechanism 62 to release the base frame locking component 61. When the basket is installed on the frame, the base frame locking component locks the base frame connecting seat relative to the basket adapter, ensuring a stable and reliable basket. During folding, the base frame assembly folds, and the base frame unlocking mechanism releases the base frame locking component, automatically unlocking the base frame connecting seat relative to the basket adapter, facilitating the folding of the basket relative to the frame.

[0077] like Figure 13-16 As shown, for reliable locking and convenient unlocking, the base frame locking assembly 61 includes base frame locking grooves 611 evenly disposed on the base frame connecting seat 22 and the basket adapter 6, and a base frame locking block 612 slidably disposed between the base frame connecting seat 22 and the basket adapter 6, which can simultaneously engage with the base frame locking grooves 611 on the base frame connecting seat 22 and the basket adapter 6. A base frame is provided between the base frame locking block 612 and the base frame connecting seat 22 for driving the base frame locking block 612 to elastically return to its original position. The locking elastic element 613; the base frame unlocking mechanism 62 includes a base frame unlocking sliding block 621 slidably disposed on the base frame connecting seat 22. The base frame unlocking sliding block 621 is linked with the base frame locking tooth block 612. The base frame unlocking sliding block 621 is configured to slide relative to the base frame connecting seat 22 when the base frame assembly 2 changes from the unfolded use state to the folded use state, so that the base frame unlocking sliding block 621 releases the lock in conjunction with the base frame locking tooth block 612.

[0078] like Figure 13-16 As shown, a base frame fixing seat 221 is fixedly connected to the base frame connecting seat 22, and the base frame fixing seat 221 is rotatably connected to the basket adapter 6; the base frame locking tooth groove 611 is located on the opposite side of the base frame fixing seat 221 and the basket adapter 6. A base frame unlocking transmission block 624 is fixedly connected to the corresponding end wall of the base frame locking tooth block 612, and the sliding direction of the base frame unlocking transmission block 624 relative to the base frame connecting seat 22 is perpendicular to the sliding direction of the base frame unlocking sliding block 621 relative to the base frame connecting seat 22, resulting in a compact structure. A base frame unlocking inclined wall 625 is provided between the base frame unlocking transmission block 624 and the base frame unlocking sliding block 621 for mutual unlocking engagement.

[0079] like Figure 13-16As shown, pivot C is located above pivot A, and pivot D is located between pivot A and pivot B. The base frame unlocking sliding block 621 is provided with an inclined base frame elongated hole 622, which is inclined downward from pivot C towards pivot D. The base frame linkage 24 is provided with a base frame unlocking drive rod 623 that can pass through the base frame elongated hole 622. When the basket is folded and the base frame linkage swings as the front and rear base frames fold towards each other, the base frame unlocking drive rod slides along the base frame elongated hole and decomposes the swing displacement of the base frame linkage through the inclined base frame elongated hole 622 into a force that drives the base frame unlocking sliding block to slide linearly, thereby linking the base frame unlocking transmission block 624 to release the base frame locking assembly. This structure directly utilizes the folding motion of the base frame linkage itself to drive the base frame unlocking mechanism through the slanted base frame elongated hole, eliminating the need for additional triggering elements or pull wires. It operates automatically and synchronously with the folding motion of the base frame components, ensuring that the base frame connecting seat is promptly released from lock during folding. The slanted base frame elongated hole matches the swing trajectory of the base frame linkage and provides the required unlocking stroke and motion tolerance, avoiding interference and jamming. When unfolded, the base frame unlocking drive rod retracts to the end of the base frame elongated hole, and the base frame unlocking mechanism has no reverse effect on the base frame locking component, ensuring safe and reliable locking. Therefore, the base frame unlocking mechanism has a simple and compact structure and is easy to integrate into the base frame connecting seat.

[0080] like Figure 1-9 As shown, for easy unlocking, the frame joint 13 includes a front joint block 131 fixedly connected to the front frame 11 and a rear joint block 132 fixedly connected to the rear frame 12 and rotatably connected to the front joint block 131. The basket also includes a canopy support rod 7, which is rotatably connected to the rear joint block 132 via the canopy joint block 71. A canopy locking assembly 72 is provided between the canopy joint block 71 and the rear joint block 132 for locking the canopy joint block 71 relative to the rear joint block 132. The canopy locking assembly 72 is configured to be released by the front joint block 131 during the folding process of the basket. A canopy unlocking button 73 is provided on the outside of the canopy joint block 71 for independently triggering the unlocking action of the canopy locking assembly 72. In this embodiment, the canopy unlocking button 73 can independently trigger the unlocking action of the canopy locking assembly 72, thereby realizing the rotational adjustment of the canopy joint block 71 relative to the rear joint block 132, and thus realizing multi-level adjustable locking. The roof locking assembly 72 is configured to lock the roof joint block 71 relative to the rear joint block 132 in multiple adjustable positions.

[0081] like Figure 1-9As shown, for reliable locking, the canopy locking assembly 72 includes canopy locking tooth grooves 721 evenly disposed on opposite sides of the rear joint block 132 and the canopy joint block 71, and canopy locking tooth blocks 722 slidably disposed between the rear joint block 132 and the canopy joint block 71 and simultaneously engaging with the canopy locking tooth grooves 721 on the rear joint block 132 and the canopy joint block 71. A canopy locking elastic element 723 for driving the canopy locking tooth block 722 to elastically reset is provided between the canopy locking tooth block 722 and the rear joint block 132. The front joint block 131 is connected to a canopy unlocking linkage block 724 for releasing the canopy locking tooth block 722 during the folding process of the basket.

[0082] like Figure 7-9 As shown, the front joint block 131 has a canopy unlocking drive rod 725 extending axially on its corresponding side wall. The canopy unlocking drive rod 725 and the canopy unlocking linkage block 724 are engaged by an anti-rotation protrusion and an anti-rotation groove to achieve linkage between them. The canopy unlocking linkage block 724 and the canopy locking tooth block 722 are provided with canopy unlocking inclined walls 7241 that unlock and engage with each other. During the upward flipping and folding process of the front frame, the front joint block 131 drives the canopy unlocking linkage block 724 to rotate accordingly through the canopy unlocking drive rod 725. The canopy unlocking linkage block 724 unlocks and engages with the two canopy unlocking inclined walls 7241 to drive the canopy locking tooth block 722 to slide accordingly until the canopy locking tooth block 722 separates from the canopy locking tooth groove 721 on the canopy joint block 71.
