There are two scale plates 11, which are located on both sides of the opening of the mounting groove 14, and the scale plates 11 have scales.

[0039] The second measuring rod 2 has a right-angle bend. One end of the second measuring rod 2 is plug-connected with the mounting groove 14 , and a limiting hole 15 is formed at the end. A limiting rod 16 is plug-connected in the limiting hole 15 .

[0040] One end of the limiting rod 16 extends out of the height measuring rod 8 through the opening of the mounting slot 14 , and the upper end of the spring 10 abuts against the bottom surface of the limiting rod 16 .

[0042] The first long hole 17 on the loading pedal 3 is arranged along its length direction. Since the lowest positions of different pedals are different when the loading pedal 3 measures different pedals, the height of the first measuring rod 1 can be adjusted by the cooperation of the first threaded column 19 and the first long hole 17, so that the first measuring rod 1 is fixed at a position flush with the lowest position of the pedal to be measured. The second measuring rod 2 is located below the first measuring rod 1. Under the elastic force of the spring 10, the second measuring rod 2 always gives the first measuring rod 1 an upward thrust.

[0045] The sliding adjustment column 23 passes through the second long hole 26 and the third long hole 29. The sliding adjustment column 23 can change the angle of the second pedaling force adjustment plate 25 by moving it. By changing the angle of the second pedaling force adjustment plate 25, the maximum angle between the second pedaling force adjustment plate 25 and the first pedaling force adjustment plate 24 changes, thereby changing the size of the pedal force. After adjusting the angle of the second pedaling force adjustment plate 25, the nut of the sliding adjustment column 23 is moved to fix it.

[0046] The semicircular side baffle 20 is provided with scales, through which the angle between the first pedaling force adjustment plate 24 and the second pedaling force adjustment plate 25 can be intuitively seen, so that the staff can make quick adjustments.

One side of the sixth long hole 39 has a scale. A circular connecting hole 40 is opened at one end of the slide rail connecting plate 31. The slide rail connecting plate 31 is connected to the threaded column at the end of the car seat slide rail through the circular connecting hole 40 and fixed with a nut.

[0050] One end of the connecting screw rod 34 with an end cap is connected to the mounting seat 30, and the other end passes through the sixth long hole 39 and penetrates the slide rail connecting plate 31. After the position of the connecting screw rod 34 is adjusted according to the scale, it is fixed with a nut.

[0051] The upper end of the second threaded column 36 at the end of the loading pedal connecting plate 32 extends out of the top surface of the mounting seat 30 through the fourth long hole 33, and the loading pedal connecting plate 32 is moved horizontally. After the position is adjusted, the loading pedal connecting plate 32 can be fixed on the mounting seat 30 by the nut on the second threaded column 36.

[0052] A seventh long hole 38 is provided on the loading pedal connecting plate 32, and a scale is provided on one side of the seventh long hole 38.

After adjusting the position of the lower end of the loading pedal 3, the guide rod 21 is fixed to the loading pedal connecting plate 32 using the nut on the guide rod 21.

[0053] The working principle of the present invention is as follows: the relative position of the heel point relative to the mounting point on the main driver's seat slide rail is calculated according to GB / T 17346-2023, the position of the second mounting tube 18 is the position of the heel point, the distance between the mounting seat 30 and the main driver's seat slide rail can be adjusted by adjusting the positions of the two connecting screws 34, and the horizontal position of the loading pedal 3 can be adjusted by adjusting the horizontal position of the loading pedal connecting plate 32, so that it can be aligned with the accelerator pedal, the brake pedal and the clutch pedal respectively, thereby realizing the measurement of different pedals. Finally, the connection position of the guide rod 21 and the loading pedal connecting plate 32 is adjusted, and finally the second mounting tube 18 is fixed at the calculated heel point position.

[0054] Then, the angle between the first pedaling force adjusting plate 24 and the second pedaling force adjusting plate 25 is adjusted according to the requirements so that the pedal force meets the requirements.

[0055] Then adjust the position of the first measuring rod 1 on the loading pedal 3 so that the first measuring rod 1 is flush with the lower edge of the pedal to be measured, that is, the lowest point.

[0056] Then fix the annular reading disk 4 on the steering wheel through the fixing clamp 6, and align the 0 scale line on the annular reading disk 4 with the alignment mark pre-made on the steering wheel, then plug and connect the first mounting tube 12 on the connecting plate 9 with the connecting rod 7 on the annular reading disk 4, and tighten the locking screw when the height measuring rod is in a vertical state.

[0057] Then insert the second measuring rod 2 into the mounting groove 14 from the lower end of the height measuring rod 8 , insert the spring 10 into the mounting groove 14 from the upper end of the height measuring rod 8 , and finally install the limiting rod 16 into the limiting hole 15 at the top end of the second measuring rod 2 .

[0058] When the second measuring rod 2 contacts the first measuring rod 1, the scale value corresponding to the top surface of the limit rod 16 is L1. Press the second measuring rod 2 down by hand to make it contact with the vehicle floor. The scale value at this time is L2. The height of the pedal to be measured from the bottom plate in the natural state is M1=L2-L1. Release the second measuring rod 2. Under the action of the spring 10, the second measuring rod 2 contacts the first measuring rod 1. Step on the loading pedal 3 with your foot until the angle between the first pedaling force adjustment plate 24 and the second pedaling force adjustment plate 25 is 0. At this time, the scale value of the top surface of the limit rod 16 is L3, the stroke of the pedal is M2=L3-L1, and the height of the pedal from the bottom plate in the stepped state is M3=M1-(L3-L1).
