As can be seen from the above, the pedal mechanism 20 of the present invention, through the arrangement of the first driving mechanism 25 and the rotating disc 23, can realize the rotation of the pedal 24; through the arrangement of the second driving mechanism 26 and the middle connecting plate 22, the left and right movement of the pedal 24 can be realized; the two motions are compounded into a curvilinear motion, so that the multi-degree-of-freedom motion of the foot is realized when a person walks. The first driving mechanism 25 and the second driving mechanism 26 provide the patient with power for assisting exercise, and can provide assisting rehabilitation exercise for the person with lower limb injury and the person suffering from stroke. Furthermore, the elliptical trainer adopts the pedal mechanism 20 of the invention, and the pedal 24 is connected with the curvilinear motion driving mechanism 30, so as to provide auxiliary motion power for the patient to walk, and the pedal 24 can move left and right and rotate, thereby being used for different exercises of different patients.
Referring collectively to fig. 6, the stride length adjustment mechanism 40 includes a stride length bar 41, a mounting bracket 42, a lead screw 44, and a slider 45. The step bar 41 has a first end 411 and a second end 412 distal from the first end 411. The mounting bracket 42 is provided with a driving motor 43. The lead screw 44 is connected to an output shaft of the drive motor 43. The slider 45 is screwed to the screw 44. Wherein, the first end 411 of the step rod 41 is fixedly connected with the sliding block 45, and when the driving motor 43 is started, the lead screw 44 drives the sliding block 45 to slide under the driving of the driving motor 43, so as to drive the step rod 41. The second end 412 of the step rod 41 is connected to the pedal mechanism 20, and specifically, the second end 412 of the step rod 41 is connected to the pedal connecting rod 28, so that the screw 44 drives the sliding block 45 to slide under the driving of the driving motor 43, and the sliding block 45 drives the step rod 41, thereby driving the pedal 24 to realize the step adjustment.
The mounting bracket 42 is fixed to the frame 10, specifically to the stand 12. The mounting bracket 42 is provided with a first supporting seat 46 and a second supporting seat 47, and the first supporting seat 46 and the second supporting seat 47 are respectively supported at both ends of the screw 44, so that the driving motor 43, the screw 44 and the slider 45 are mounted on the mounting bracket 42. The reason why the first support seat 46 and the second support seat 47 are provided is that the lead screw 44 belongs to an elongated member, and needs to rotate and linearly move at the same time when working, and the slider 45 is further in threaded connection with the lead screw, so that the lead screw 44 may be damaged or even broken during the movement of the lead screw 44, and meanwhile, the lead screw is also easy to shake during the movement, and the two support seats are provided at the two ends of the lead screw 44, thereby avoiding the above situations to a certain extent.
Of course, even though the first supporting seat 46 and the second supporting seat 47 are provided at both ends of the screw 44, there is a possibility that the screw 44 may swing during the movement, and for this reason, a slide rail 48 is provided between the first supporting seat 46 and the second supporting seat 47, the slide rail 48 may be fixed to the mounting bracket 42 and arranged in parallel with the screw 44, and the slider 45 is slidably connected to the slide rail 48. Therefore, in the moving process of the screw 44, the slide rail 48 can share a part of the force for the screw 44, and meanwhile, because the slide block 45 is slidably connected with the slide rail 48, in the moving process of the screw 44, the slide rail 48 can also play a role in guiding, so that the screw 44 can be effectively prevented from shaking in the moving process, and further the pedal mechanism 20 is prevented from shaking.
Referring to fig. 7, by adjusting the distance L1 with the setting of the step length adjusting mechanism 40, the distance change L2 can be finally realized, and the adjusting parameters of an embodiment of the present invention are shown in table 1.
Table 1:
L1(mm) 0 30 60 90 120 150 180 210 240 270 290
L2(mm) 1450 1431 1411 1392 1372 1353 1333 1313 1293 1273 1260
from the above table, it can be seen that by changing the position of the step bar 41, the position of the foot pedal 24 can be changed, thereby adjusting the step length of the person walking.
In summary, the step length adjusting mechanism 40 of the present invention can drive the step length rod 41 by the driving motor 43. When the elliptical machine for rehabilitation is provided with the step length adjusting mechanism 40, the step length can be automatically adjusted within a certain range, so that the elliptical machine for rehabilitation is convenient to use and can ensure the safety of people with lower limbs injured and people suffering from stroke.
