[0033] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0034] like Figures 1-4 As shown, a foldable seat includes an upper frame 1, a seat plate 4 and a lower frame 5.

[0035] The upper frame 1 is configured as a U-shaped rod structure, and both ends of the U-shape of the upper frame 1 are rotatably connected to the connecting rod 2. The upper frame 1, the connecting rod 2 and the first cloth cover 3 can form a receiving cavity with an opening.

[0036] The seat plate 4 is accommodated in the accommodating cavity, and one end of the seat plate 4 is rotatably connected to the connecting rod 2 , and can be folded and retracted into the upper frame 1 during the rotation of the seat plate 4 .

[0037] Among them, the lower frame 5 is set to a U-shaped rod structure, and the two ends of the U-shape of the lower frame 5 are rotatably connected to the connecting rod 2. The lower frame 5 and the upper frame 1 are transmission-connected through the connecting rod 2, and the lower frame 5 is set outside the accommodating cavity. The lower frame 5 can be folded and retracted into the upper frame 1 or contact the upper frame 1 during the rotation process.

[0038] Specifically, the upper frame 1, the connecting rod 2 and the first cloth cover 3 can form a receiving cavity with an opening, and the seat plate 4 is accommodated in the cavity. When the folding seat is fully unfolded, the seat plate 4 contacts the first cloth cover 3 during the rotation process, so that the cavity volume reaches the maximum.

[0039] In this embodiment, the rotatable connection between the upper frame 1, the seat plate 4 and the lower frame 5 is utilized to realize the folding function of the seat. The folding seat can reduce the occupied space by folding when not in use, and can be easily moved when the place of use needs to be changed. It has good flexibility and portability. At the same time, after folding, the seat plate 4 and the lower frame 5 are accommodated in the upper frame 1, or the design of the lower frame 5 contacting the upper frame 1 saves more space than conventional folding seats.

[0040] like Figures 1-4 As shown, based on the above embodiment, the upper frame 1 is provided with a first contact edge 11, and the lower frame 5 is provided with a second contact edge 51. When the lower frame 5 is in a folded state, the second contact edge 51 contacts the first contact edge 11.

[0041] In this embodiment, after the lower frame 5 is folded, the second contact edge 51 contacts the first contact edge 11, so that the lower frame 5 is relatively parallel to the upper frame 1, which greatly reduces the space occupied by the folding seat after folding, making it more convenient to carry and store.

[0042] like Figures 1-4As shown, on the basis of the above embodiment, it also includes a rotating part 6, and the rotating part 6 includes a rotating inner part 61 and a rotating outer part 62, the rotating inner part 61 and the rotating outer part 62 are rotatably connected, the rotating inner part 61 is connected to one of the upper frame 1 and the lower frame 5, and the rotating outer part 62 is connected to the other of the upper frame 1 and the lower frame 5.

[0043] Specifically, the upper frame 1 is connected to the rotating inner portion 61 , and the lower frame 5 is connected to the rotating outer portion 62 . The rotating inner portion 61 and the rotating outer portion 62 are rotatably connected, so that the upper frame 1 and the lower frame 5 can achieve relative rotation.

[0044] In this embodiment, the design of the rotating inner portion 61 and the rotating outer portion 62 facilitates the maintenance and replacement of components of the rotating portion 6 after a problem occurs, thereby reducing the maintenance cost after a problem occurs.

[0045] like Figures 1-4 As shown, on the basis of the above embodiment, the rotating part 6 also includes a locking gear 63, the rotating inner part 61 is provided with a locking inner groove 611, and the rotating outer part is provided with a locking outer groove (not shown in the figure). When the locking gear 63 is simultaneously engaged with the locking inner groove 611 and the locking outer groove, the rotating part 6 is locked, and the relative positions of the upper frame 1 and the lower frame 5 are fixed. When the locking gear 63 is only engaged with the locking inner groove 611, the rotating part 6 is unlocked, and the lower frame 5 can rotate relative to the upper frame 1.

[0046] In this embodiment, when the engaging gear 63 is engaged with the engaging inner groove 611 and the engaging outer groove at the same time, the mutual restraint in their structures causes the rotating part 6 to be in a locked state. At this time, the relative positions of the upper frame 1 and the lower frame 5 are fixed, thereby ensuring the stability of the entire device and preventing unexpected movement or rotation.

[0047] like Figures 1-4 As shown, on the basis of the above embodiment, the rotating part 6 is further provided with an elastic member 64 and a pressing cover 65, one end of the elastic member 64 is in contact with the rotating inner part 61, and the other end of the elastic member 64 is in contact with the engaging gear 63. The thrust provided by the elastic member 64 to the engaging gear 63 makes it in a position engaged with the engaging inner groove 611 and the engaging outer groove. Pressing the pressing cover 65 can push the engaging gear 63 to separate from the engaging outer groove.

[0048] Specifically, when the pressing cover 65 is pressed, the engaging gear 63 is disengaged from the engaging outer groove, thereby releasing the locking state of the rotating portion 6 and allowing the lower frame 5 to rotate freely relative to the upper frame 1. Conversely, after the pressing cover 65 is released, the engaging gear 63, under the action of the elastic member 64, re-engages with the engaging inner groove 611 and the engaging outer groove, locking the rotating portion 6 again and maintaining the relative position of the upper frame 1 and the lower frame 5 unchanged.

[0049] In this embodiment, the elastic member 64 drives the latching gear 63 to move toward the latching outer groove when the pressing cover 65 is not subjected to force, so that when the entire latching outer portion rotates relative to the latching inner portion, the latching gear 63 engages with the latching outer groove, thereby locking the rotating part 6.

[0050] like Figures 1-4 As shown, on the basis of the above embodiment, a through hole 621 is further provided on the outside of the snap-in, the pressing cover 65 is accommodated in the through hole 621, the pressing cover 65 is provided with a snap-in hook 651, and a snap-in groove (not shown) is provided on the inner wall of the snap-in through hole 621, and the snap-in hook 651 is accommodated in the snap-in groove.

[0051] Specifically, the pressing cover 65 contacts the engaging gear 63 , and under the action of the elastic member 64 , the engaging gear 63 pushes the pressing cover 65 to move until the engaging barb 651 of the pressing cover 65 contacts one end of the engaging slot.

[0052] In this embodiment, the snap-fitting hook 651 of the pressing cover 65 moves in the snap-fitting groove, which can not only prevent the pressing cover 65 from rotating when sliding, but also limit the maximum protruding distance of the snap-fitting cover, thereby ensuring the stability of the pressing cover 65 during movement.

[0053] like Figures 1-4 As shown, based on the above embodiment, it further includes a connecting portion 7 and a safety handrail 8. The connecting portion 7 is provided on the upper frame 1, and the safety handrail 8 is detachably connected to the connecting portion 7.

[0054] In this embodiment, the safety armrest 8 can be detachably connected to the upper frame 1 through the connecting portion 7. The safety armrest 8 can be removed when not needed, which facilitates the use of the seat in different occasions and increases flexibility, which is especially important in an environment with limited space.

[0055] like Figures 1-4 As shown, on the basis of the above embodiment, the safety handrail 8 is provided with a clamping block 81, and the connecting part 7 is further provided with a clamping groove 71. When the safety handrail 8 is connected to the connecting part 7, it is connected to the clamping groove 71 through the clamping block 81.

[0056] In this embodiment, the clamping block 81 is provided on the safety handrail 8, and the clamping block 81 can be raised or lowered on the safety handrail 8. The safety handrail 8 is accommodated in the clamping groove 71 on the connecting portion 7 through the clamping block 81, thereby being connected to the clamping portion.

[0057] like Figures 1-4 As shown, based on the above embodiment, when the clamping block 81 is installed in the clamping groove 71, an inclined surface 811 is provided at the contact point between the clamping block 81 and the connecting portion 7, and the safety handrail 8 can be installed to the connecting portion 7 by pressing the clamping block 81 through the inclined surface 811.

[0058] Specifically, the inclined surface 811 is arranged on one side of the clamping block 81 close to the connecting part 7. During the process of installing the safety handrail 8 to the connecting part 7, the inclined surface 811 first contacts the connecting part 7, thereby pushing the clamping block 81 to sink until the clamping block 81 moves to the clamping groove 71 and then rises again. At this time, the clamping block 81 contacts the four sides of the clamping groove 71, thereby limiting the movement of the safety handrail 8.

[0059] In this embodiment, the contact between the inclined surface 811 and the connecting portion 7 can directly push the clamping block 81 down until it is accommodated in the clamping groove 71, making it both labor-saving and convenient for the user to install the safety handrail 8.

[0060] like Figures 1-4 As shown, on the basis of the above embodiment, the clamping block 81 is further provided with a pressing block 812 . Pressing the pressing block 812 can drive the clamping block 81 to be recessed, thereby disengaging the clamping block 81 from the clamping groove 71 .

[0061] Specifically, the pressing block 812 is connected to the clamping block 81 and protrudes from the surface of the safety handrail 8 .

[0062] In this embodiment, when the user wants to remove the safety handrail 8, he only needs to apply a certain force on the pressing block 812 to make the clamping block 81 follow the pressing block 812 to sink and eventually disengage from the clamping groove 71, so that the user can easily remove the safety handrail 8.
