Example

[0021] To address the issue of existing mobility scooters not being able to be folded quickly, reference was made to... Figures 1-5 As shown, this application discloses a foot-operated folding mobility scooter including a chassis frame 10, a seat 20 and a backrest 30. The front bottom of the chassis frame is connected to a front wheel assembly 50 via a reversing assembly 40, and the rear bottom of the chassis frame is connected to a rear wheel assembly 80 via a brake-type drive assembly 70. A power supply assembly 90 electrically connected to the brake-type drive assembly is provided on the rear bottom of the chassis frame. The reversing assembly extends upward through the chassis frame and connects to a foldable control lever 60; The seat is foldably connected to the chassis frame via bracket assembly 100; The support assembly is connected to a foot folding assembly 110 under the seat for easy folding of the seat; the backrest is detachably foldable and connected to the rear side of the seat.

[0022] In one specific embodiment, the front wheel assembly includes an arc-shaped tube, two front wheel bodies, two first U-shaped parts, and two cylinders. The two front wheel bodies are rotatably connected to the two first U-shaped parts, and the two cylinders are rotatably disposed in the two first U-shaped parts, and the two cylinders are connected by the arc-shaped tube. The front wheel assembly of this application includes an arc-shaped tube 54, two front wheel bodies 51, two first U-shaped members 52, and two cylinders 53. The two front wheel bodies are rotatably connected to the two first U-shaped members, and the two cylinders are rotatably disposed in the two first U-shaped members, and the two cylinders are connected by the arc-shaped tube. The reversing assembly includes a sleeve 41, a reversing shaft 42, a connecting piece 43, a torsion screw 46, and two connecting rods 44. The sleeve is fixed to one side of the chassis frame. Bearings 411 are installed at the upper and lower ends of the sleeve. The lower end of the control lever passes through the sleeve and the two bearings and is connected to the connecting piece. A first cylinder 45 is connected to the upper part of the control lever. Two connecting rods connect two first U-shaped parts to the connecting piece respectively. A steering wheel 62 is connected to the upper end of the control lever, and a second cylinder 63 is connected to the lower end of the control lever. The surfaces of the first cylinder and the second cylinder that are in contact with each other are provided with meshing teeth 632 and 452. Internal threaded posts 631 and 451 are respectively provided in the center of the first cylinder and the second cylinder. When the torsion screw is screwed into or out of the internal threaded posts of the first cylinder and the second cylinder, the first cylinder and the second cylinder are fixed or separated.

[0023] When the user performs a reversing operation, the user drives the control lever through the steering wheel to make the reversing shaft rotate in the sleeve. During this process, the connecting plate will drive the front wheel body to rotate on the cylinder through the connecting rod. Since the direction of the front wheel body changes, the purpose of reversing is achieved.

[0024] When folding the joystick, the user loosens the torsion screw, causing the screw to disengage from the first cylinder. At this point, the user can rotate the joystick to fold the joystick.

[0025] In one specific embodiment, the rear wheel assembly includes two rear wheel bodies 81, which are respectively disposed at the bottom of the chassis frame; The brake-driven drive assembly includes a brake motor 71, a coupling 72, and a drive axle 73.

The brake motor is connected to the drive axle via the coupling, and the two rear wheels are coaxially connected via the drive axle. In addition, the brake motor of this application is equipped with a brake handle. When in use, the brake motor, coupling and drive axle work together to drive the two rear wheels to rotate, thereby enabling the entire mobility scooter to move. When the user operates the brake handle, the brake motor will stop moving, thereby stopping the entire mobility scooter from moving.

[0026] In one specific embodiment, the bracket assembly includes two side plates 101, two second U-shaped members 102, two first diagonal braces 108 and two second diagonal braces 109. The two side plates are fixed to the bottom sides of the seat, and the two second U-shaped members are disposed on the upper sides of the chassis frame.

The top of the first diagonal brace is provided with a first snap-fit ​​groove 1081 that mates with the snap-fit ​​shaft; The inner side of the second U-shaped part is provided with a cam groove 1021, and the bottom inner side of the second inclined plate is provided with a convex shaft 1091 that slides in the cam groove.

[0027] In conjunction with the bracket assembly structure, the foot-operated folding assembly includes a foot pedal 112, two mounting plates 111, and two spring members 115. The two mounting plates are rotatably mounted on the inner sides of the two U-shaped members, and the top of each mounting plate is provided with a second snap-fit ​​groove 1111 that mates with a convex shaft. A first bolt 113 is provided on the opposite side surface of each of the two U-shaped members, and a second bolt 114 is provided on the opposite side surface of each of the two mounting plates. Each spring member is connected to a first bolt and a second bolt, and the foot pedal is positioned between the two mounting plates.

[0028] When the user presses the foot pedal and folds the seat, the first and second diagonal braces will rotate, the first locking groove will separate from the locking shaft, and the cam shaft will slide in the cam groove and separate from the locking shaft until the seat is laid flat on the chassis frame.

[0029] In one specific embodiment, L-shaped connectors 21 are provided on both sides of the rear of the seat. The interior of the two L-shaped connectors is provided as slots (not shown). Two connecting tubes 31 are provided on both sides of the backrest. The two connecting tubes are detachably fixed in the slots of the two L-shaped connectors by a third bolt 22. When the user loosens the third bolt, the backrest can be rotated, thereby achieving quick folding.

[0030] In one specific embodiment, armrests 150 are detachably provided on both sides of the bottom of the seat.

[0031] In one specific embodiment, the armrest includes an L-shaped bend 151 and an armrest body 152.
