[0030] A support rod 5 is fixed to the side of each rear support rod 4; a groove is formed on the side of the support rod 5, and the groove is connected to the backrest frame 6 in a matching manner; brackets 8 are rotationally connected to both sides of the seat plate frame 9, and the other end of the bracket 8 is rotationally connected to an armrest plate 7; the armrest plate 7 and the side of the seat plate frame 9 are rotationally connected to a backrest frame 6, and the backrest frame 6 is connected to the support rod 5 in a matching manner.

[0031] When the walking aid seat structure of the present utility model is unfolded, as Figure 1 and Figure 2 shown, the front support rod 3 and the rear support rod 4 support the seat plate frame 9, the seat plate frame 9 is perpendicular to the bracket 8, the bracket 8 is perpendicular to the armrest plate 7, and the end of the backrest frame 6 is located in the groove of the support plate 5;

[0032] When folding up, as Figure 8 shown, the front support rod 3 and the rear support rod 4 are parallel to the mobile base 1, the backrest frame 6 is separated from the support plate 5, and the seat plate frame 9, the bracket 8, the armrest plate 7, and the backrest frame 6 are in an approximately parallel stacked state.

[0036] When unfolded, the connecting rod 22 and the supporting seat 26 are on a horizontal line. Figure 3 As shown, at this time, the upwardly extending portion of one end of the limit plate 24 limits the connecting rod 22, and the latch 23 is inserted into the connecting rod 22 and a corresponding limit hole 25 to complete the fixation;

[0037] When folding, the connecting rod 22 drives the rod body 21 to rotate to another limiting hole 25. At this time, the latch 23 is inserted into the connecting rod 22 and the other limiting hole 25 to fix the folded operating rod 2. Figure 8 shown.

[0038] The seat structure of the scooter of the utility model is in a state of being Figure 8 The folded state shown needs to be unfolded when needed. The operation steps are as follows:

[0039] First, pull out the latch 23 and rotate the rod body 21 until the rod body 21 is blocked by the upward extension of the limit plate 24. At this time, the operating rod 2 is unfolded, and then the latch 23 is inserted between the corresponding limit hole 25 and the connecting rod 22. Figure 3 As shown, the operating lever 2 is unfolded, and then the seat frame 9 is pulled to drive the front support rod 3 and the rear support rod 4 to rotate to the right, as shown in FIG.

Fig. 9 As shown, the backrest frame 6 is then pushed to the left, so that the front support rod 3 and the rear support rod 4 are rotated to the left by a certain distance. At this time, the backrest frame 6 enters the groove of the support rod 5, and the seat structure of the scooter is initially formed. Then, the pull pin 92 is inserted to complete the reinforcement, as shown in FIG. Figure 1 and Figure 2 shown.

[0040] When the seat structure of the scooter is folded, the pull pin 92 is pulled out and the backrest frame 6 is pulled upward. At this time, the front support rod 3 and the rear support rod 4 are driven to move to the right until the rear support rod 4 contacts the inclined plate 13, and then the front support rod 3 and the rear support rod 4 stop rotating, and the backrest frame 6 is disengaged from the groove of the support rod 5, and then the backrest frame 6 is rotated to the left, and the front support rod 3 and the rear support rod 4 are rotated to the left.
