[0068] See also Figures 1 to 10 , this embodiment provides a folding basket, including a basket body 1, a handle 3, a locking tongue 5 and a slider 4;

[0069] The housing 1 includes a bottom plate 15, a first side plate 11 and a second side plate 12, and has a structure as follows: Figure 1As shown, the first side panel 11 and the second side panel 12 are hinged to the bottom panel 15 respectively. The first side panel 11 includes a panel body 111 and a flip door 112. The structure is as shown in FIG. Figure 2 、 Figure 3 and Figure 4 As shown, the second side plate 12 is connected to the plate body 111 through the snap structure 2, and the structure is as follows Figure 5 As shown, the plate body 111 is provided with an opening 113 for accommodating a flip door 112 and a lock hole 52 . The flip door 112 is hinged to the plate body 111 for covering or opening the opening 113 .

[0070] The flip door 112 is provided with a handle 3 that can move along the height direction of the first side panel 11, and a lock tongue 5 that can move along the length direction of the first side panel 11. The panel body 111 is provided with a slider 4 that can move along the length direction of the first side panel 11. The lock tongue 5 and the slider 4 are respectively located on both sides of the handle 3 in the length direction of the first side panel 11. The structure is as follows: Figure 6 As shown;

[0071] The handle 3 is used to drive the lock tongue 5 to move along the length direction of the first side panel 11 so that the lock tongue 5 is inserted into or disengaged from the lock hole 52, thereby locking or unlocking the flip door relative to the panel body 111, wherein the lock tongue 5 is inserted into the lock hole 52, the panel body 111 and the second side panel 12 are locked, and the lock tongue 5 is disengaged from the lock hole 52, and the panel body 111 and the second side panel 12 are unlocked, or the handle 3 is used to drive the slider 4 to move along the length direction of the first side panel 11 to release the clamping state of the panel body 111 and the second side panel 12.

[0072] Different from the existing technology, the above technical solution provides a folding basket. The user opens the flip door 112 to expose the opening 113 of the plate body 111. The internal items can be picked up through the opening 113, which improves the convenience of use. Through the design of the handle 3, the lock tongue 5 and the slider 4, the basket can be quickly locked, unlocked and unfolded. After the basket 1 is unlocked, it can be folded into a flat plate, which is convenient for carrying and storage.

[0073] See also Figure 6 In this embodiment, when the handle 3 is at the initial position, if it moves upward along the height direction of the first side plate 11 (such as Figure 6 As shown by the y1 arrow), the slider 4 can be driven to move along the length direction of the first side plate 11 (as shown in FIG. Figure 6 As shown by the x1 arrow), to release the clamping state of the plate body 111 and the second side plate 12, if it moves downward along the height direction of the first side plate 11 (as shown by the x1 arrow), Figure 6 As shown by the y2 arrow, the lock tongue 5 can be driven to move along the length direction of the first side plate 11 so that the lock tongue 5 is inserted into or out of the lock hole 52 (out of the lock hole 52 as shown in FIG. Figure 6As shown by the x2 arrow), the plate body 111 is locked or unlocked.

[0074] In some embodiments, when the handle 3 is in the initial position, if it moves downward along the height direction of the first side panel 11, the slider 4 can be driven to move along the length direction of the first side panel 11 to release the clamping state of the panel body 111 and the second side panel 12. If it moves upward along the height direction of the first side panel 11, the lock tongue 5 can be driven to move along the length direction of the first side panel 11 so that the lock tongue 5 is inserted into or disengaged from the lock hole 52, thereby locking or unlocking the panel body 111 and the flip door 112.

[0075] See also Figure 7 In this embodiment, the folding basket further includes a first elastic member 6, which is disposed on the flip door 112 and the lock tongue 5 and is used to drive the lock tongue 5 to reset. In one embodiment, when resetting, the lock tongue 5 is inserted into the lock hole 52. The user drives the handle 3 downward along the height direction of the first side panel 11. The lock tongue 5 moves inward along the length direction of the first side panel 11 (toward the center of the flip door 112), disengaging from the lock hole 52, and the panel body 111 and the flip door 112 are unlocked. The first elastic member 6 deforms and stores energy. When the user releases the handle 3, the first elastic member 6 drives the lock tongue 5 to move outward along the length direction of the first side panel 11 (toward the outside of the flip door 112), thereby locking the lock tongue 5 and the lock hole 52. This not only improves operational convenience but also reduces the force required by the user, thereby reducing the number of user operations.

[0076] An elastic member refers to a component or material capable of elastic deformation. The first elastic member 6 can undergo a certain degree of elastic deformation when subjected to an external force and quickly return to its original shape after the external force disappears. This ability is called elasticity. The first elastic member 6 can be a coil spring, a rubber strip, a rubber band, etc. Preferably, the first elastic member 6 is a coil spring disposed along the length of the first side panel 11, with one end of the coil spring sleeved over the protrusion of the lock tongue 5 and the other end sleeved over the protrusion of the flip door 112.

[0077] In some embodiments, the folding basket is not provided with a first elastic member, the locking tongue is close to the locking hole, and the locking tongue and the locking hole are attracted together by magnetism to lock the plate body and the flip door. The handle is moved to push the locking tongue away from the lock hole to unlock the plate body and the flip door.

[0078] See also Figure 7In this embodiment, the folding basket further includes a second elastic member 7, which is disposed on the panel body 111 and the slider 4 and along the length of the first side panel 11. This member is used to reset the slider 4. In one embodiment, the slider 4 is reset while the engagement is still intact. When the user actuates the handle 3 upward along the height of the first side panel 11, the slider 4 moves outward along the length of the first side panel 11 (toward the outside of the flip door 112), releasing the engagement between the panel body 111 and the second side panel 12. The second elastic member 7 then deforms and stores energy, allowing the slider 4 to move inward along the length of the first side panel 11 (toward the center of the flip door 112). This not only improves operational convenience but also reduces the force required by the user, reducing the number of user operations.

[0079] In this embodiment, the second elastic member 7 can be a coil spring, a rubber strip, a rubber band, etc. Preferably, the second elastic member 7 is a coil spring provided along the length direction of the first side plate 11 .

[0080] See also Figure 6 In this embodiment, the folding basket further includes a third elastic member 8, which is provided on the flip door 112 and the handle 3 and is used to drive the handle 3 to reset, thereby achieving a more convenient folding and unfolding operation. As an embodiment, when the handle 3 is reset, it is in the initial position mentioned above.

[0081] See also Figure 1 and Figure 6 In this embodiment, the third elastic member 8 includes a first elastic strip 81 and a second elastic strip 82. The first elastic strip 81 is responsible for returning the handle 3 to its original position after the handle 3 moves upward along the height of the first side panel 11, while the second elastic strip 82 is responsible for returning the handle 3 to its original position after the handle 3 moves downward along the height of the first side panel 11. The flip door 112 is provided with a first positioning groove 115 and a second positioning groove 116. The first positioning groove 115 is located above the handle 3 along the height of the first side panel 11. One end of the first elastic strip 81 is connected to the handle 3, and the other end is connected to the first positioning groove 115. When a user moves the handle 3 upward along the height of the first side panel 11, the first elastic strip 81 is deformed by the force, storing energy. When the user releases the handle 3, the first elastic strip 81 drives the handle 3 downward to its initial position. The second positioning groove 116 is located below the handle 3 along the height of the first side panel 11. One end of the second elastic strip 82 is connected to the handle 3, and the other end is connected to the second positioning groove 116. The user drives the handle 3 to move downward along the height direction of the first side plate 11, and the second elastic strip 82 is deformed by the force to store energy. When the user releases the handle 3, the second elastic strip 82 drives the handle 3 to move upward to the initial position.

[0082] In this embodiment, the first elastic strip 81 and the second elastic strip 82 are metal or plastic elastic strips. The first elastic strip 81 / the second elastic strip 82 can be connected to the plate body 111 by plugging (inserting the elastic strip into the groove), which is convenient for assembly. At the same time, the first elastic strip 81 / the second elastic strip 82 can be connected to the handle 3 by plugging.

[0083] See also Figure 5 In this embodiment, the snap-fit ​​structure 2 includes a spring piece 21. The second side plate 12 is provided with the spring piece 21, and the spring piece 21 can be bent along the thickness direction of the second side plate 12. The spring piece 21 can be an elastic member formed by cutting the second side plate 12. When not squeezed and pushed by the slider 4, the spring piece 21 is flush with the second side plate 12. When squeezed and pushed by the slider 4, the spring piece 21 is deformed. The inner side wall of the spring piece 21 is provided with a first snap-fit ​​portion 22, and the outer side wall of the plate body 111 is provided with a second snap-fit ​​portion 23 corresponding to the first snap-fit ​​portion 22. The first snap-fit ​​portion 22 and the second snap-fit ​​portion 23 on the spring piece 21 can be buckled together to form a snap-fit ​​state. Even if the chassis is subjected to slight vibration or external force, the snap-fit ​​structure 2 can remain stable and is not easy to separate on its own, thereby enhancing the integrity and stability of the chassis. Driven by the handle 3, the slider 4 pushes the spring 21 to bend along the outer side of the folding basket, separating the first and second snap portions 22 and 23, thereby releasing the engagement between the panel body 111 and the second side panel 12. By utilizing the bending properties of the spring 21 and moving the slider 4, the snap mechanism 2 can be quickly separated. The user can simply release the engagement between the panel body 111 and the second side panel 12 by driving the slider 4 via the handle 3, thereby improving ease of use.

[0084] See also Figure 5 In this embodiment, the first snap-fit ​​portion 22 is a snap-fit ​​block, and the second snap-fit ​​portion 23 is a snap-fit ​​slot. When the snap-fit ​​block and the snap-fit ​​slot are correctly aligned, the plate body 111 and the second side plate 12 can be snapped together to maintain stability. In some embodiments, the first snap-fit ​​portion 22 is a snap-fit ​​slot, and the second snap-fit ​​portion 23 is a snap-fit ​​block.

[0085] See also Figure 5 In this embodiment, the outer side wall of the first latch portion 22 is provided with a guiding inclined surface 24 for the plate body 111 to slide. The guiding inclined surface 24 can be a smooth inclined surface or an inclined surface with a specific shape and texture to facilitate the plate body 111 to slide thereon. Figure 5 It is shown that the left outer side wall and the lower outer side wall of the first snap portion 22 are both provided with a guiding slope 24. The plate body 111 flips up from the left side, and the plate body 111 is guided by the guiding slope 24 to achieve the positioning of the first snap portion 22 and the second snap portion 23, thereby avoiding the protruding first snap portion 22 from hindering the expansion of the plate body 111.

[0086] See also Figure 6 and Figure 7 In this embodiment, the handle 3 is provided with a first guide structure 31 and a second guide structure 32, and the slider 4 is provided with a third guide structure 41. The handle 3 moves upward along the height direction of the first side panel 11 and, through the linkage between the first guide structure 31 and the third guide structure 41, drives the slider 4 to move outward along the length direction of the first side panel 11. The lock tongue 5 is provided with a fourth guide structure 51. The handle 3 moves downward along the height direction of the first side panel 11 and, through the linkage between the second guide structure 32 and the fourth guide structure 51, drives the lock tongue 5 to move inward along the length direction of the first side panel 11. The user only needs to move the handle 3 to drive the slider 4 and the lock tongue 5 to move accordingly, simplifying the operation process.

[0087] See also Figure 6 and Figure 7 In this embodiment, the first guiding structure 31 , the second guiding structure 32 , the third guiding structure 41 , and the fourth guiding structure 51 are all guiding inclined surfaces inclined in the same direction. Figure 6 The third guide structure 41 and the fourth guide structure 51 on the right side are shown to be tilted from left to right, with the left higher and the right lower. Correspondingly, the first guide structure 31 and the second guide structure 32 are also tilted from left to right. Figure 6 The third guide structure 41 and the fourth guide structure 51 on the left side are shown to be inclined from right to left - the left is lower and the right is higher. The linkage process is achieved through the interaction of the guiding inclined surfaces. The user drives the handle 3 to move upward along the height direction of the first side plate 11, and the slider 4 moves along the inclined surface driven by the handle 3 to complete the outward movement. The handle 3 is driven to move downward along the height direction of the first side plate 11, and the lock tongue 5 moves along the inclined surface driven by the handle 3 to complete the inward movement, which can ensure the accuracy and consistency of the operation. In addition, this design also has a high anti-interference ability. Even if the chassis is subjected to slight vibration or external force, the linkage between the components can still remain stable, and it is not easy to cause misoperation or self-movement.

[0088] In this embodiment, the sliding movement of the lock tongue 5, slider 4, and handle 3 is achieved by means of a sliding structure. Generally, the sliding structure includes a slide groove, in which the lock tongue 5, slider 4, and handle 3 are respectively disposed. By presetting the direction of the slide groove, the movement path of the lock tongue 5, slider 4, and handle 3 can be controlled. For example, a first slide groove is provided on the panel body 111 along the length of the first side panel 11, and the slider is slidably connected to the first slide groove. A second slide groove is provided on the flip door 112 along the length of the first side panel 11, and the lock tongue 5 is slidably connected to the second slide groove. A third slide groove is provided on the flip door 112 along the height of the first side panel 11, and a sliding portion is provided on the handle, which is slidably connected to the third slide groove via the sliding portion.

[0089] See also Figure 7 In this embodiment, a first restricting structure is provided between the lock tongue 5 and the flip door 112. The first restricting structure restricts (limits) the movement of the lock tongue 5 along the lengthwise direction of the first side panel 11, thereby preventing the lock tongue 5 from falling off the flip door. Optionally, a first restricting protrusion 53 is provided on the upper and / or lower side of the lock tongue 5, and the first chute is provided with a first notch for the first restricting protrusion 53 to extend therethrough. The flip door is provided with first restricting walls on either side of the first restricting protrusion 53. The first restricting walls exert a restricting (limiting) effect by obstructing the first restricting protrusion 53. The first restricting walls and the first restricting protrusion 53 form a first restricting structure.

[0090] See also Figure 7 In this embodiment, a second limiting structure is provided between the slider 4 and the panel body 111. This second limiting structure restricts (limits) the movement of the slider 4 along the lengthwise direction of the first side panel 11, thereby preventing the slider 4 from falling off the panel body. Optionally, a second limiting protrusion 42 is provided on the upper and / or lower side of the slider 4, and the second chute is provided with a second notch through which the second limiting protrusion 42 extends. The flip door is provided with second limiting walls on either side of the second limiting protrusion 42. The second limiting walls exert a limiting (limiting) effect by obstructing the second limiting protrusion 42. The second limiting walls and the second limiting protrusion 42 form a second limiting structure.

[0091] See also Figure 2 and Figure 4 In this embodiment, the panel body 111 has areas 114 on either side of the opening 113 that overlap with the flip door 112. The handle 3 extends into area 114 but does not extend beyond the flip door 112. The slider 4 extends into area 114, meaning that sliders 4 are present both within area 114 and outside of it. When the flip door 112 is closed, its sides overlap with the two areas 114 of the panel body 111, allowing the ends of the handle 3 to contact the sliders 4. The handle 3 unlocks the two side panels of the basket body 1 by pushing against the sliders 4. This reduces wear on the handle 3 and extends the life of the folding basket.

[0092] See also Figure 1 、 Figure 9 and Figure 10In this embodiment, the housing 1 further includes a third side panel 13 and a fourth side panel 14. The third and fourth side panels 13, 14 are respectively hinged to the bottom panel 15. The second and third side panels 12 and 13 have the same structure and are disposed opposite each other. The second and third side panels 12, 13 are respectively engaged with the panel body 111 via a snap-fit ​​structure 2. Sliders 4 are provided on both sides of the handle 3, and both side panels can be unlocked using a single handle 3. The first and fourth side panels 11, 14 are disposed opposite each other, and the second and third side panels 12, 13 are respectively engaged with the fourth side panel 14 via a snap-fit ​​structure 2.

[0093] In this embodiment, the structure of the first side panel 11 and the structure of the fourth side panel 14 can be the same or different. The same structure of the first side panel 11 and the fourth side panel 14 means that the fourth side panel 14 also has the same panel body, flip door 112, and handle 3, lock tongue 5, and slider 4 as the first side panel 11. The different structure of the first side panel 11 and the fourth side panel 14 means that the fourth side panel 14 is a complete side panel and does not have the flip door 112 like the first side panel 11. Figure 1 As shown, the fourth side panel 14 is provided with a handle 3 and a slider 4 for releasing the engagement with the second side panel 12 / the third side panel 13. In addition, the handle 3 may also be provided with a third elastic member, and the handle is reset through the upper and lower first elastic strips and the second elastic strip.

[0094] See also Figure 1 In this embodiment, the length of the first side panel 11 is shorter than that of the second side panel 12. The length of the first side panel 11 is the same as that of the fourth side panel 14, and the length of the second side panel 12 is the same as that of the third side panel 13. That is, the first side panel 11 and the fourth side panel 14 are the short side panels, and the second side panel 12 and the third side panel 13 are the long side panels. When the chassis 1 is unfolded, it forms a rectangular chassis 1. The advantage of using the first side panel 11 as the short side panel is that the handle 3 can be made shorter, which facilitates precise control of locking and unlocking.

[0095] See also Figure 8 and Figure 9 In this embodiment, the second side panel 12 is provided with a folded edge 16, which is connected to the panel body 111 via a limiting structure 9. The limiting structure 9 can better maintain the stability of the panel body 111 and the second side panel 12 after they are unfolded. The limiting structure 9 further prevents the panel body 111 from folding outward, that is, the first side panel 11 and the second side panel 12 are perpendicular to the bottom panel 15 after they are unfolded.

[0096] See also Figure 8 and Figure 9In this embodiment, the limiting structure 9 includes a limiting protrusion 91 and a limiting groove 92. The limiting protrusion 91 can be provided on the folding edge 16, and the limiting groove 92 can be provided on the plate body 111, or the limiting protrusion 91 can be provided on the plate body 111, and the limiting groove 92 can be provided on the folding edge 16. Figure 8 The limiting protrusion 91 on the plate body 111 is L-shaped, correspondingly, Figure 9 The limiting groove 92 on the folded edge 16 is also L-shaped and extends through both sides of the folded edge 16 along the thickness direction. The limiting protrusion 91 is adapted to the limiting groove 92 to form an insert, limiting the two side panels, effectively preventing the first side panel 11 from deflecting or rotating, and ensuring the stability of the panel structure.

[0097] See also Figure 1 and Figure 10 In this embodiment, the third side panel 13 is also provided with a folded edge 16, which is also connected to the panel body 111 via the limiting structure 9. In addition, the second side panel 12 and the third side panel 13 are both provided with folded edges 16 on both sides in the longitudinal direction. The second side panel 12 and the third side panel 13 are respectively connected to the fourth side panel 14 via the folded edges 16 and the limiting structure 9.

[0098] When the basket is unfolded, the first side panel, the second side panel, the third side panel and the fourth side panel are perpendicular to the bottom panel, and two adjacent side panels are locked by the snap structure and the limiting structure.

[0099] The step of storing the housing is that the user moves upward along the height direction of the first side plate (such as Figure 6 The handle drives the slider 4 to move outward along the length direction of the first side plate (as shown by the y1 arrow). Figure 6 The outer spring piece is pushed up to release the engaging state of the snap structure, and the plate body and the second side plate / the third side plate are separated, so that the first side plate can be swung downward to fit the bottom plate; similarly, the user moves the handle upward along the height direction of the fourth side plate 14, driving the slider on the fourth side plate to move outward along the length direction of the fourth side plate, and the outer spring piece is pushed up to release the engaging state of the snap structure, and the fourth side plate and the second side plate / the third side plate are separated, so that the first side plate can be swung downward to fit the bottom plate, and finally the second side plate and the third side plate are swung downward.

[0100] The steps for opening the flip door are as follows: the user moves downward along the height direction of the first side panel (eg Figure 6 The handle drives the lock tongue to move along the length direction of the first side plate 11 (as shown by the y2 arrow). Figure 6 The lock tongue is disengaged from the lock hole, and the flip door swings outward to open the opening.
