However, traditional pedal deflection testing methods often rely on manual operation, which is not only inefficient but also susceptible to human factors, resulting in insufficient accuracy and reliability. To address these issues, we propose an deflection test mechanism for pedal testing machines. Utility Model Content

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0017] Reference Figure 1-2 , an offset testing mechanism for a pedal detection machine, comprising a slide 1, a drive motor 2 fixedly installed on the left side of the slide 1, the drive motor 2 is transmission-connected to the slide 1, a moving block 3 is transmission-installed on the top of the slide 1, a mounting plate 4 is fixedly installed on the top of the moving block 3, slide grooves 8 are provided on the left and right sides of the top of the mounting plate 4, sliders 9 are slidably installed inside the two slide grooves 8, and detection rods 5 are fixedly installed on the tops of the two sliders 9, and tension sensors 6 are fixedly installed on one side of the two slide grooves 8 near the center of the mounting plate 4, and one side of the two tension sensors 6 is fixedly connected to one end of the corresponding slider 9.

[0018] The driving motor 2 can drive the moving block 3 to move left and right through the slide 1, and can move the moving block 3 to the required position. During the inspection of the foot pedal, the foot pedal is fixed and the pedal part of the foot pedal is located between the two detection rods 5. Then the driving motor 2 is started to drive the moving block 3 to move, so that one of the detection rods 5 contacts the pedal and pushes the pedal. At this time, the pedal gives the same reaction force to the detection rod 5, and the tension sensor 6 will detect the thrust received by the detection rod 5, so that the force required when the foot pedal is deflected can be measured; similarly, the force required when the foot pedal is deflected in the other direction can be detected according to the above steps.

[0019] A capacitive sensing portion 7 is provided at the upper end of the detection rod 5. The capacitive sensing portion 7 can be designed based on the capacitive sensing principle. The contact time of the detection rod 5 and the pedal and whether the detection rod 5 is in contact with the pedal are judged by the change in capacitance before and after when the detection rod 5 is in contact with the pedal.

[0020] An infrared distance sensor 10 is fixedly mounted on one side of the detection rod 5, and distance measuring plates 11 are fixedly mounted on both the left and right sides of the top of the slide 1. The two infrared distance measuring sensors 10 face the two distance measuring plates 11 respectively.

[0021] When the detection rod 5 pushes the pedal to move, the offset distance of the pedal can be measured by the infrared distance sensor 10 .
