DETAILED DESCRIPTION
[0018] Example, by Figure 1-3It is given that the utility model includes two mounting frames 1, a fixing rod 2 is fixedly connected between the two mounting frames 1, a movable rod 3 is installed in front of the fixing rod 2, the movable rod 3 is movably connected between the two mounting frames 1, the connection between the mounting frame 1 and the movable rod 3 is movably connected through a bearing, a fixing seat 5 is fixedly connected to the bottom of the fixing rod 2, a screw stepper motor 4 is fixedly connected to the bottom of the fixing seat 5 by bolts, a connecting seat 8 is fixedly provided on the outer end of the fixing rod 2, one end of the output shaft of the screw stepper motor 4 is movably connected to the bottom of the connecting seat 8 through a pin shaft, two left and right distributed pedal fixing frames 7 are installed in front of the movable rod 3, and a telescopic force arm 6 is installed on the rear side of the pedal fixing frame 7.
[0019] The telescopic force arm 6 includes a lifting force arm 61, which is composed of an arm plate 611 and an L-shaped arm plate 612. The arm plate 611 is located below the movable rod 3. The arm plate 611 and the L-shaped arm plate 612 are movably connected by a pin shaft, and the L-shaped arm plate 612 is fixedly sleeved on the outer end of the movable rod 3. The side of the arm plate 611 away from the L-shaped arm plate 612 is movably connected to the pedal fixing frame 7 by a pin shaft. The lifting force arm 61 is the main driving structure. While lifting the bottom of the pedal fixing frame 7, it will also drive the arm plate 2 621 in the auxiliary force arm 62 to move forward slightly.
[0020] The telescopic force arm 6 also includes an auxiliary force arm 62, which is composed of arm plate 2 621, arm plate 3 622 and arm plate 4 623. The front side of arm plate 2 621 is movably connected to the pedal fixing frame 7 through a pin shaft, and arm plate 4 623 is fixedly sleeved on the outer end of the fixing rod 2. Arm plate 3 622 is movably connected between arm plate 2 621 and arm plate 4 623 through a pin shaft. The bending part of the L-shaped arm plate 612 is movably connected to arm plate 2 621 through a pin shaft. The auxiliary force arm 62 is mainly used to cooperate with the lifting force arm 61 to install the pedal fixing frame 7 and adjust the angle, and the extension of each component is adaptive operation when the lifting force arm 61 lifts the pedal fixing frame 7.
[0021] The pin connection between the arm plate 2 621 and the pedal fixing frame 7 is located above the pin connection between the arm plate 1 611 and the pedal fixing frame 7, and the connection points between the telescopic force arm 6 and the pedal fixing frame 7 are distributed up and down, so that the stability of the pedal fixing frame 7 can be maintained and it is convenient to lift or lower it.
[0022] Working principle:
[0023] In actual use, a pedal is fixedly installed on the front side of the two pedal fixing frames 7. When the pedal on the pedal fixing frame 7 needs to be tilted and lifted from the vertical state, the screw stepper motor 4 can be started, and the output shaft of the screw stepper motor 4 moves linearly. When the output shaft of the screw stepper motor 4 moves to the front side, it will drive the movable rod 3 to rotate through the connecting seat 8. When the movable rod 3 rotates, it can drive the L-shaped arm plate 612 to rotate. During this period, the L-shaped arm plate 612 will push the bottom of the pedal fixing frame 7 to be lifted through the arm plate 1 611, and the pedal lift installed on the pedal fixing frame 7 will be lifted. During the operation of the lifting arm 61, the arm plate 2 621 connected to the pin shaft of the L-shaped arm plate 612 will also move forward to a certain extent, thereby adaptively lifting and pushing the top of the pedal fixing frame 7, and the arm plate 3 622 will adaptively rotate between the arm plate 2 621 and the arm plate 4 623 through the pin shaft as the arm plate 2 621 moves. The entire auxiliary arm 62 will automatically make adaptive movements as the lifting arm 61 operates, ultimately lifting the pedal fixing frame 7 and the pedal mounted on the pedal fixing frame 7, thereby facilitating the support of the user's foot.
