[0034] Referring to Figures 1 to 10 , the ankle exercise frame comprises a leg frame 1, a foot frame 2, a first electric push rod 3, and a driving mechanism 4; the foot frame 2 is slidably arranged on the lower side of the leg frame 1 and is driven to stretch and retract up and down by the first electric push rod 3, thereby satisfying the adjustment for different leg lengths when used and realizing the stretching and traction action on the lower leg.

[0035] More specifically, the leg frame 1 is welded by two parallel leg vertical rods 11 and a leg horizontal rod 12, the back frame 21 is welded by two foot vertical rods 211 and a foot horizontal rod 212, the two foot vertical rods 212 are slidably matched with the two leg vertical rods 12, and are positioned at a specific position by the first electric push rod 3.

[0036] The foot frame 2 comprises a back frame 21 and an L-shaped foot plate frame 22 hinged to the lower end of the back frame 21, and a driving mechanism 4 is arranged between the back frame 21 and the L-shaped foot plate frame 22, which drives the L-shaped foot plate frame 22 to perform pitching movement, i.e. to drive the foot stretching and compression action.

[0037] The driving mechanism 4 has the following two types:

[0038] I. A second electric push rod 31 is hinged at one end to the back frame 21 and at the other end to the L-shaped foot plate frame 22; the second electric push rod 31 is extended to drive the front end of the L-shaped foot plate frame 22 to rise, forming a compression action on the foot; the second electric push rod 31 is retracted to drive the front end of the L-shaped foot plate frame 22 to lower, realizing the stretching action on the foot, so as to achieve the purpose of ankle joint exercise, which can be used as a rehabilitation equipment and also as a fitness and massage equipment.

[0039] II. The driving mechanism 4 comprises a motor 41, a gearbox 42, a crank 43 and a connecting rod 44; the motor 41 is connected to the gearbox 42 and fixed to one of the back frame 21 and the L-shaped foot plate frame 22; the crank 43 is locked at one end to the output shaft 421 of the gearbox after speed reduction and connected at the other end to one end of the connecting rod 44 through a hinge shaft, and the other end of the connecting rod 44 is hinged to one of the back frame 21 and the L-shaped foot plate frame 22; the motor 41 drives the crank to rotate one revolution to drive the L-shaped foot plate frame 22 to pitch once. The advantage of the crank 43 driving is that the motor does not need to be frequently switched between forward and reverse rotation.

[0040] Further, the foot frame 2 is also provided with a travel switch 5 corresponding to the stop position, which is arranged on the back frame 21 and can be touched by the components of the driving mechanism in motion, such as Figure 1 which can be touched by the first electric push rod 3 or the connecting rod 44. The travel switch 5 is triggered once every time the L-shaped foot plate frame 22 pitches once, and the instruction is only valid after the stop instruction is triggered. The stop position refers to the state that the L-shaped foot plate frame 22 is in contact with the leg frame 1 and perpendicular to the leg frame 1 for storage, which is especially suitable for being matched with a massage chair.

[0041] Referring to Figure 11 , the leg frame 1 is also provided with a mountain-shaped pad 13 for resting the double legs, and a clamping device for fixing the double leg parts is arranged on the mountain-shaped pad 13; the L-shaped foot plate frame 22 of the foot frame is provided with a double palm bin 23 for resting the double feet, and a clamping device for fixing the foot parts is also arranged on the double palm bin 23. The conventional clamping device has the following two types:

[0042] I. The clamping device is a woven belt, and the woven belt is provided with a quick-release type plug buckle or a magic buckle at the tightening end; the woven belt is used to constrain and position the double leg parts and the double foot parts to improve the stretching efficiency.

[0043] II. The clamping device is an air bag, which is arranged on the side walls of the two grooves of the mountain-shaped pad 13 and on the side walls of the double-palm bin 23, and clamps and positions the legs and feet by means of the air bag. This is a common scheme in lower limb massage equipment. In addition to the clamping and restraining effect, the expansion and contraction of the air bag also forms a massage effect.
