Detailed Embodiment

[0016] The following further elaborates on the overall solution of the present utility model in detail in conjunction with the drawings and specific embodiments:

[0017] See Figure 1 、 2, the structure of the specific embodiment of the present utility model includes an upper mounting plate 4, a lower mounting plate 8, a cylinder 2, linear bearings 5, a movable plate 6, a slider plate 7, a bearing mounting block 11, a pressure reducing valve 1, a speed regulating valve 3, a solenoid valve 10, and a PLC controller 9. The upper mounting plate 4 and the lower mounting plate 8 are connected by four linear bearings 5. The four linear bearings 5 are symmetrically arranged in pairs around the upper mounting plate 4. The linear bearings 5 serve as linear guides and also as fixing brackets. The cylinder 2 is fixedly mounted on the upper mounting plate 4 and fixed by nuts. The upper mounting plate 4 is provided with a central hole. The cylinder shaft of the cylinder 2 extends out from the central hole of the upper mounting plate 4 and is connected to the movable plate 6 between the upper mounting plate 4 and the lower mounting plate 8. The movable plate 6 is movably connected to the linear bearings 5 through the bearing mounting block 11. The center of the movable plate 6 is provided with a central hole. The cylinder shaft passes through the central hole of the movable plate 6 and is connected and fixed to the movable plate 6 by nuts. A slider plate 7 is arranged below the movable plate 6. The pressure reducing valve 1 is connected to the solenoid valve 10 through an air pipe. The PLC controller 9 is connected to the solenoid valve 10. The solenoid valve 10 is arranged on the cylinder. The solenoid valve 10 includes two air holes. There are two speed regulating valves 3, which are respectively arranged at the top and bottom of the cylinder 2 and communicated with the cylinder 2. The two air holes are respectively connected to the two speed regulating valves 3.

[0018] See Figure 2 , the structure of the specific embodiment of the slider plate 7 of the present utility model is composed of a linear guide 7.1, a slider 7.2, and a slider mounting plate 7.3. The linear guide 7.1 is fixed to the movable plate 6 by screws. The slider mounting plate 7.3 is fixed to the slider 7.2 by screws. The slider 7.2 is movably connected to the linear guide 7.1 and can slide along the linear guide 7.1.

[0019] The working principle of the present utility model is as follows:

[0020] Fix the foot pedal of the hand-cranked and foot-pedaled integrated power generation device on the slider mounting plate 7.3 through cable ties. During the simulated foot-pedaling process, since the foot pedal has an arc-shaped movement trajectory, the arc-shaped movement is decomposed into a horizontal displacement and a vertical displacement. The vertical displacement is driven by the vertical displacement of the movable plate 6, and the horizontal displacement is the horizontal displacement of the slider 7.2 along the linear guide 7.1.

[0021] The set pressure of the pressure reducing valve 1 is 0.8 MPa. The pressure reducing valve 1 is connected to the solenoid valve 10 through an air pipe. The PLC program of the PLC controller 9 is a square wave signal with a period of 0.7 seconds, where the positive half-cycle pulse width is 0.4 seconds and the negative half-cycle pulse width is 0.3 seconds. The PLC controller 9 controls the opening and closing of two air holes of the solenoid valve 10 through pulses. The two air holes are respectively connected to a speed regulating valve 3 and are respectively connected to the top and bottom of the cylinder 2. When compressed gas is connected, the PLC controller 9 is powered on to control the solenoid valve 10 to cycle open and close. At this time, the compressed gas will alternately enter the top and bottom of the cylinder 2 through the solenoid valve 10 and the speed regulating valve 3 in turn, so as to drive the cylinder 2 to perform vertical reciprocating motion to do work. The slider plate 7 is an auxiliary motion mechanism that generates a reciprocating displacement in the horizontal direction. The vertical displacement of the cylinder 2 and the horizontal displacement of the slider plate 7 are combined into a reciprocating circular motion trajectory. Thus, the test effect of simulating foot stepping on the integrated power generation device is achieved.
