[0028] The present invention will be further described in detail below with reference to embodiments:
[0029] Example 1
[0030] like Figure 1-4 As shown, this utility model provides an accelerator pedal testing device, including a device frame 1 and an accelerator pedal 2. A support rod 4 is rotatably connected to one side of the accelerator pedal 2 via a bearing 5. A guide cylinder 7 is slidably sleeved on the outer wall of the support rod 4. A height adjustment component is provided above the guide cylinder 7.
[0031] A return spring 8 is sleeved on the outer wall of the end of the support rod 4 away from the shaft seat 5, and one end of the return spring 8 is fixedly connected to one end of the guide slide cylinder 7;
[0032] A linear displacement sensor 3 is fixedly connected to the outer wall of the guide slide 7. The detection end of the linear displacement sensor 3 is fixedly connected to the outer wall of the support rod 4 near one end. An angle sensor 6 is provided on one side of the bearing seat 5.
[0033] The height adjustment assembly includes a height adjustment threaded rod 9, and a fixed cylinder 10 is threadedly connected to the outer wall of the height adjustment threaded rod 9. The top end of the fixed cylinder 10 is fixedly connected to the top of the inner wall of the equipment frame 1, and the bottom end of the height adjustment threaded rod 9 is rotatably connected to the outer wall of the guide slide cylinder 7.
[0034] Example 2
[0035] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a vertical slide 15 is fixedly connected to one side of the equipment frame 1, and the inner wall of the vertical slide 15 is slidably connected to the outer wall of the support rod 4.
[0036] Angle sensor 6 is used to monitor the angle of rotation of accelerator pedal 2 around the axis. A pedal spring 14 is fixedly connected to one side of accelerator pedal 2, and one end of pedal spring 14 is fixedly connected to the fixed end of bearing 5.
[0037] A pressure sensor 12 is fixedly connected to the center of one side of the accelerator pedal 2. A positioning ring 13 is fixedly connected to the outer wall of the linear displacement sensor 3, and the positioning ring 13 is fixedly connected to the outer wall of the guide slide 7.
[0038] A knob 11 is fixedly connected to the top of the height adjustment threaded rod 9.
[0039] The working principle of this accelerator pedal testing device will be explained in detail below.
[0040] like Figure 1-4 As shown, the accelerator pedal testing device performs performance testing on the accelerator pedal 2 in the following way: one side of the accelerator pedal 2 is rotatably connected to the support rod 4 via a bearing 5, allowing the accelerator pedal 2 to rotate around the bearing 5. When a pressing force is applied to the accelerator pedal 2, the accelerator pedal 2 rotates around the bearing 5, causing the support rod 4 connected to it to slide within the guide tube 7. At this time, the linear displacement sensor 3 detects the displacement change of the support rod 4, the angle sensor 6 monitors the angle of rotation of the accelerator pedal 2 around the pivot point, and the pressure sensor 12 measures the pressure applied to the accelerator pedal 2. Through the coordinated work of these three sensors, various performance parameters of the accelerator pedal 2 during operation can be accurately obtained.
[0041] The height adjustment component is used to adjust the height position of the guide slide 7. Specifically, rotating the knob 11 drives the height adjustment threaded rod 9 to rotate. Since the height adjustment threaded rod 9 is threadedly connected to the fixed cylinder 10 and the fixed cylinder 10 is fixed to the top of the inner wall of the equipment frame 1, the rotation of the height adjustment threaded rod 9 will cause it to move axially, thereby driving the guide slide 7 to move up and down, so as to adjust the height of the guide slide 7 to meet the testing requirements of different models of accelerator pedal 2.
[0042] During the test, the pedal spring 14 provides a restoring force to the accelerator pedal 2, ensuring that the accelerator pedal 2 can return to its initial position after the pressing force is removed; the return spring 8 provides a restoring force to the support rod 4, ensuring that the support rod 4 can return to its initial position after sliding, thereby ensuring the stability and reliability of the test device.
[0043] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
