[0024] The front support frame assembly 4 includes an articulated frame 41, a universal wheel 42 and a first connecting plate 43. The articulated frames 41 are symmetrically provided on both sides of the bottom of the mounting steel frame 1. The articulated plates 7 are made of an arc-shaped structure. The ends of the articulated plates 7 are respectively hinged to the backrest tube 10 and the articulated frames 41. When the articulated plates 7 are pulled, the articulated frames 41 can be driven to flip. A first connecting plate 43 is provided between the two sets of articulated frames 41. The bottom of the articulated frames 41 is provided with a universal wheel 42.

[0025] A rear retaining frame assembly 6 is provided in the middle part of the bottom of the mounting steel frame 1, and the rear retaining frame assembly 6 includes a first socket 61, a connecting frame 62, a rear driven wheel 63, a first latch 64, a second socket 65, a rotating plate 66, a second connecting plate 67 and a locking screw 68. A connecting frame 62 is hinged between the two sides of the middle of the bottom of the mounting steel frame 1, and a hinge seat is provided inside the connecting frame 62. The electric push rod 5 is located inside the hinge seat. The output end of the electric push rod 5 is hinged to the mounting steel frame 1, so that the electric push rod 5 can move and deflect in the process of pushing the seat cushion 3 to avoid its extension and contraction being restricted. Rear driven wheels 63 are symmetrically provided on both sides of the bottom of the connecting frame 62, and first sockets 61 are symmetrically provided on both sides of the connecting frame 62. A first latch 64 is provided inside the first socket 61, and multiple groups of second sockets 65 are provided at one end of the hinge plate 7. Second connecting plates 67 are symmetrically provided on both sides of the mounting steel frame 1, and a rotating plate 66 is provided on one side of the second connecting plate 67, and a locking screw 68 is provided on one side of the rotating plate 66.

[0026] The handlebar assemblies 8 are symmetrical on both sides of the mounting steel frame 1. The handlebar assemblies 8 include a second pin 81, a third socket 82, a support plate 83 and a support rod 84. Support rods 84 are symmetrically provided at one end of both sides of the mounting steel frame 1. A support plate 83 is provided on the top of the support rod 84. A mounting groove is provided at the bottom of the support plate 83, and the top of the support rod 84 is located inside the mounting groove, so that the support plate 83 can be installed on the top of the support rod 84 and connected to the support rod 84.

A third socket 82 is provided on one side of the support plate 83 and the backrest tube 10, and a second pin 81 is provided inside the third socket 82.

[0027] Working principle: When the seat needs to be folded, first pull out the first latch 64 and the second latch 81. At this time, the first latch 64 is no longer locked in the inside of the hinge plate 7, and the third socket 82 no longer locks the position of the backrest tube 10. Then, the locking screw 68 is rotated by rotating the plate 66, and then the locking screw 68 is screwed out of the inside of the connecting frame 62, so that the second connecting plate 67 is no longer connected to the connecting frame 62. Then, the backrest tube 10 is flipped forward, so that the bottom of the backrest tube 10 pulls one end of the hinge plate 7 to move upward. During the upward movement of one end of the hinge plate 7, the other end pulls the hinge frame 41 to flip toward the position of the mounting steel frame 1, so that the entire hinge frame 41 is attached to the mounting steel frame 1. Finally, the connecting frame 62 is flipped, thereby completing the folding of the seat.

[0028] When the seat is in use, the electric push rod 5 is started by the power box 9, and the electric push rod 5 extends to push one end of the seat cushion 3 to flip upward, thereby changing the angle of the seat cushion 3 to facilitate the auxiliary user.
