a seat assembly 100 including a seat frame assembly 110 and a back frame assembly 130, the back frame assembly 130 being rotatably coupled to the seat frame assembly 110 and being rotatable relative to the seat frame assembly 110 to a first folded position folded with the seat frame assembly 110 or to a first unfolded position unfolded relative to the seat frame assembly 110; wherein the backrest frame assembly 130 is located above the seat frame assembly 110, and can be folded and unfolded as described above;

a frame assembly 200, the frame assembly 200 rotatably coupled to the seat frame assembly 110, and a front wheel assembly 300 and a rear wheel assembly 400 coupled to the frame assembly 200 and rotatable with the frame assembly 200 relative to the seat frame assembly 110 to a second folded position folded with the seat frame assembly 110, or rotatable with the frame assembly 200 such that the seat frame assembly 110, the front wheel assembly 300 and the rear wheel assembly 400 support one another to maintain an unfolded second unfolded position. Wherein the frame assembly 200 is located below the seat frame assembly 110 and the front wheel assembly 300 and the rear wheel assembly 400 are located at both ends of the lower portion of the frame assembly 200, when the scooter is unfolded for use, the front wheel assembly 300 and the rear wheel assembly 400 are unfolded by the frame assembly 200 for forming a support for the seat assembly 100.

After the backrest frame assembly 130 is folded, the frame assembly 200 can be folded as required, specifically, the frame assembly 200 is rotatably connected to the seat frame assembly 110, for example, the frame assembly 200 is rotatably connected to the seat frame assembly 110 in a certain angle range, so that when the scooter is unfolded for use, the frame assembly 200 can be rotated to a second unfolding position shown in fig. 1, wherein the frame assembly 200 and the seat assembly 100 can be relatively fixed by a limiting assembly or a fixing assembly, thereby preventing relative movement between the frame assembly 200 and the seat assembly 100, and ensuring stability of the frame assembly 200 in use. When the scooter needs to be folded and stored, the frame assembly 200 can be folded relative to the seat frame assembly 110 by removing the limiting function of the limiting assembly or the fixing assembly, so that the whole occupied space of the scooter is further reduced.

The range of angles that the back frame assembly 130 can rotate relative to the seat frame assembly 110 can be controlled by the first limit assembly, and when the back corner assembly 130 rotates to the first folding position or the first unfolding position, the back frame assembly 130 abuts against the first limit assembly, and the rotation of the back frame assembly 130 relative to the seat frame assembly 110 is limited. Thus, after the backrest frame assembly 130 is unfolded or folded, the user can conveniently use or store the scooter.

For another example, the first stopper assembly may be detachably coupled to the seat frame assembly, or the first stopper assembly may have an angle adjusting function, so that the angle at which the back frame assembly 130 is unfolded may be adjusted by replacing or adjusting the first stopper assembly.

Alternatively, in one embodiment of the present application, as shown in fig. 1-4, the frame assembly 200 may include a first frame assembly 210 and a second frame assembly 220, the front wheel assembly 300 and the rear wheel assembly 400 being respectively connected to two ends of the first frame assembly 210, a first end of the first frame assembly 210 being pivotally connected to the seat frame assembly 110, a second end of the first frame assembly 210 being connected to a first end of the second frame assembly 220, and a second end of the second frame assembly 220 being connected to the seat frame assembly 110;

For example, after the seat assembly 100 is folded, the frame assembly 200 may be folded according to the need of the storage space, in the normal use state, the first frame assembly 210 may not rotate relative to the seat frame assembly 110, and a stable supporting function needs to be ensured, the rotation of the seat frame assembly 110 and the first frame assembly 210 may be restricted by using the second frame assembly 220, the triangle connection structure as shown in fig. 1 may be formed, when the folding is needed, the restriction of the second frame assembly 220 is removed, the connection between the second frame assembly 220 and the seat frame assembly 110/the first frame assembly 210 may be removed, so that the first frame assembly 210 may rotate relative to the seat frame assembly 110, or the structure of the second frame assembly 220 itself may be changed, for example, a telescopic or foldable structure is used, so that one side of the triangle connection structure may be changed in length or shape, so that the angle between the other two edges can be varied. Thereby enabling folding of the carriage assembly 200.

Optionally, in an embodiment of the present application, the second frame assembly 220 is one of a folding assembly, a telescoping assembly, and a detachable bracket assembly.

For another example, the second frame component 220 is a telescopic component, two ends of the second frame component are respectively rotatably connected with the first frame component 210 and the seat frame component 110, and as the second frame component 220 is telescopic, in the triangular connection structure, the length of one side corresponding to the second frame component 220 is changed, so that the angle between the first frame component 210 and the seat frame component 110 is changed, and thus the first frame component 210 can be rotated to a second unfolding position or a second folding position relative to the seat frame component 110.

For another example, the second frame assembly 220 may also be a folding assembly that is folded by the second frame assembly 220 such that the first frame assembly 210 is rotated to a second unfolded position or a second folded position relative to the seat frame assembly 110.

For example, the locking mechanism 223 may be a bolt or a bolt, the first folding tube 221 and the second folding tube 222 are correspondingly provided with matching mounting holes, when the first folding tube 221 and the second folding tube 222 are opened to form the structure shown in fig. 1, the bolt or the bolt is embedded into the mounting holes to complete the locking function, and when the first folding tube 221 and the second folding tube 222 need to be folded, the corresponding mounting holes are pulled out or screwed out, so that the side of the triangular connection structure corresponding to the second frame assembly 220 is changed, and the first frame assembly 210 rotates relative to the seat frame assembly 110.

For another example, the locking mechanism 223 may also be a movable sleeve, when the scooter is used, the movable sleeve is ensured to be sleeved on the first folding tube 221 and the second folding tube 222, when the scooter needs to be folded, the movable sleeve is moved to be sleeved only on the first folding tube 221 or the second folding tube 222, and the first folding tube 221 and the second folding tube 222 can rotate.

In this embodiment, a first end of the pedal support frame 212 is rotatably connected to the first frame assembly 210, a foldable pedal 211 is mounted on a second end of the pedal support frame 212, when the scooter is folded, the pedal support frame 212 can rotate relative to the first frame connecting frame 214, and rotate counterclockwise as shown in fig. 1-3, and rotate to a third folding position where the first frame connecting frame 214 is folded, so that the space occupied by the folded scooter in the horizontal direction is smaller. When the scooter is unfolded for use, the footrest support bracket 212 rotates to a third unfolded position unfolded relative to the first frame connecting bracket 214, providing the user with use of the footrest 211. The first frame attachment bracket 214 is used to provide mounting structure for the footrest support bracket 212 and to connect the second frame assembly 220 to the seat frame assembly 110 to form the triangular attachment structure described in the previous embodiments.

For example, the first frame connecting frame 214 may further be provided with a storage slot for storing the pedal support frame 212 when the scooter is folded. So that the whole occupied space after the scooter is folded is smaller.

Optionally, in an embodiment of the present application, a second limiting assembly may be disposed on the first frame assembly 210, and the second limiting assembly limits the rotation of the footrest support frame 212 along the rotation axis when the footrest support frame 212 rotates to the third folded position or the third unfolded position relative to the first frame connecting frame 214.

The seat frame assembly 110 may further include an armrest pivot frame assembly 120 for limiting a pivot angle of the armrest frame assembly, the armrest frame assembly 140 may pivot within a certain angle through the armrest pivot frame assembly 120, and when the scooter is in use, the armrest frame assembly 140 may pivot to the angle shown in fig. 1, which is a fourth unfolded position, and the armrest frame assembly 140 may be used by a user; when the scooter needs to be folded, the scooter rotates to the angle shown in fig. 3, and the scooter is in the fourth folding position, so that the occupied space of the scooter in the vertical direction is reduced. Thereby enabling folding of the seat assembly 100.

Optionally, in an embodiment of the present application, a third position-limiting assembly is disposed on the seat frame assembly 110, and the third position-limiting assembly limits the rotation of the armrest frame assembly 140 along the rotation axis when the armrest frame assembly 140 rotates to the fourth folded position or the fourth unfolded position relative to the seat frame assembly 110. The third position-limiting component can be disposed on the armrest rotating shaft component 120 or disposed on the armrest frame component 140.

Optionally, in an embodiment of the present application, the scooter may further include a linkage assembly, any one of the back frame assembly 130, the first frame connecting frame 214, the pedal support frame 212 and the armrest frame assembly 140 is uniformly connected to the linkage assembly, and when one of the back frame assembly 130, the first frame connecting frame 214, the pedal support frame 212 and the armrest frame assembly 140 rotates, at least one of the back frame assembly 130, the first frame connecting frame 214, the pedal support frame 212 and the armrest frame assembly 140 is driven to rotate through the linkage assembly.

For example, the walker may further include a first linkage assembly by which the back frame assembly 130 is pivotally coupled to the armrest frame assembly 140. When the backrest frame assembly 130 rotates, the first linkage assembly can drive the armrest frame assembly 140 to rotate when the backrest frame assembly 130 rotates, so that steps of the scooter for folding are reduced. The linkage assembly may be a structure in which a transmission rod is matched with a gear, or a structure in which a synchronous belt is matched with a synchronous wheel, so that the seat assembly 100 is changed as shown in fig. 1 to 3 during the folding process of the scooter.

For another example, the scooter may further include a third linkage assembly, and the first frame connecting frame 214 is rotatably linked with the footrest support frame 212 through the third linkage assembly. Through the third linkage assembly, when the first frame connecting frame 214 rotates relative to the seat frame assembly 110, the linkage rotation of the first frame connecting frame and the seat frame assembly can be realized, so that the steps required for folding and opening the scooter are further simplified, and the third linkage assembly can be arranged inside the first frame connecting frame 214. Through the third linkage assembly, the first linkage assembly and the second linkage assembly are combined, so that the backrest frame assembly 130, the armrest frame assembly 140, the first frame connecting piece or the pedal support frame 212 can be folded or unfolded, and the rest mechanisms are synchronously folded or unfolded, so that the folding and the opening of the scooter can be completed.
