Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides an automotive brake fatigue life testing device, including a base frame 1, a fixing plate 2 fixedly installed on one side of the top of the base frame 1, a first mounting frame 3 installed on the top of the fixing plate 2, a guide slide column 4 installed on the other side of the top of the base frame 1, a slider 5 slidably connected to the middle of the guide slide column 4, a movable frame 6 connected to the top of the slider 5, a second mounting frame 7 fixedly connected to the top of the movable frame 6, a foot pedal mounting plate 8 provided on one side of the second mounting frame 7, a brake pedal 22 installed in the middle of the foot pedal mounting plate 8, a power assist spring 23 provided on one side of the brake pedal 22, a height adjustment block 9 fixedly installed on one side of the foot pedal mounting plate 8, a lifting bolt 10 threadedly connected to the middle of the height adjustment block 9, a movable block 16 fixedly connected to the bottom of the movable frame 6, a horizontal bolt 17 threadedly connected to the middle of the movable block 16, and a center rod 11 provided on the top of the first mounting frame 3;

[0018] In this embodiment, the brake pedal 22 to be tested is installed in the middle of the foot pedal mounting plate 8, and the pressing end of the brake pedal 22 corresponds to one side of the brake pedal 22. Then, the height and horizontal position of the brake pedal 22 are adjusted so that the pressing end can contact the thrust wheel 20.

[0019] See Figures 1-4 One end of the horizontal bolt 17 is rotatably set to one side of the top of the base frame 1. A handle 24 is installed on the end of the horizontal bolt 17 and the top of the lifting bolt 10. The top of the lifting bolt 10 is rotatably connected to the top of the second mounting frame 7. The height adjustment block 9 is located on the side of the foot pedal mounting plate 8 away from the first mounting frame 3. A locking sleeve 15 is provided at the connection between the middle rod 11 and the first mounting frame 3. The mounting shell 12 is located below the middle rod 11. Fixed sleeves 18 are fixedly connected to both sides of the top of the mounting shell 12. The fixed sleeves 18 are slidably connected to the surface of the middle rod 11, and a locking bolt 19 is threadedly connected to the top of the fixed sleeves 18. A slide rail 26 is provided on the side of the second mounting frame 7 near the foot pedal mounting plate 8. The foot pedal mounting plate 8 is slidably connected to the slide rail 26.

[0020] In this embodiment, rotating the horizontal bolt 17 allows the moving block 16 and the moving frame 6 to move under the action of the thread. The moving frame 6 slides with the guide slide column 4 above the base frame 1 via the slider 5. The horizontal movement of the moving frame 6 allows the second mounting frame 7 and the foot pedal mounting plate 8 to move, thereby causing the brake pedal 22 mounted on the foot pedal mounting plate 8 to move horizontally, thus completing the adjustment of the horizontal position.

[0021] See Figures 1-4 The middle rod 11 is provided with a mounting shell 12 in the middle, and an electric push cylinder 14 is installed in the middle of the mounting shell 12. A push wheel 20 is installed at the output end of the electric push cylinder 14, and a pedal force sensor 21 is provided at the connection between the electric push cylinder 14 and the push wheel 20. The pressing end of the brake pedal 22 is in contact with the push wheel 20. Several fixed base blocks 13 are fixedly connected to the bottom of the base frame 1, and a fixing hole 25 is provided in the middle of the fixed base block 13.

[0022] In this embodiment, rotating the lifting bolt 10 can cause the height adjustment block 9 to rise or fall under the action of the thread. The height adjustment block 9 will pull the foot pedal mounting plate 8 up and down to move it. The foot pedal mounting plate 8 slides up and down on one side of the second mounting bracket 7, so that the brake pedal 22 installed on the foot pedal mounting plate 8 will also move up and down, thus completing the vertical height adjustment of it.

[0023] In practical use, the automotive brake fatigue life testing device of this utility model installs the brake pedal 22 to be tested in the middle of the foot pedal mounting plate 8, with the pressing end of the brake pedal 22 corresponding to one side of the brake pedal 22. Then, the height and horizontal position of the brake pedal 22 are adjusted so that the pressing end can contact the thrust wheel 20. Specifically, by rotating the horizontal bolt 17, the moving block 16 and the moving frame 6 can be moved under the action of the thread. The moving frame 6 slides with the guide slide column 4 above the base frame 1 through the slider 5. The horizontal movement of the moving frame 6 can move the second mounting frame 7 and the foot pedal mounting plate 8, thereby causing the brake pedal 22 installed on the foot pedal mounting plate 8 to move horizontally, completing the horizontal position adjustment. By rotating the lifting bolt 10, the height adjusting block 9 can be raised or lowered under the action of the thread. The height adjustment block 9 pulls the foot pedal mounting plate 8 up and down, causing the foot pedal mounting plate 8 to slide up and down on one side of the second mounting bracket 7. As a result, the brake pedal 22 mounted on the foot pedal mounting plate 8 also moves up and down, completing the vertical height adjustment. After adjustment, the pressing end of the brake pedal 22 contacts the thrust wheel 20. At this time, the electric push cylinder 14 is activated to push the thrust wheel 20 to apply a certain pressure to the brake pedal 22, simulating the action of pedaling. In conjunction with the pedal force sensor 21, the pressure is detected. By applying different pressures, the reset status of the brake pedal 22 is observed, completing the test and inspection of the brake pedal 22. This facilitates the fatigue life test of the brake pedal 22. The entire device greatly facilitates the pressure test of the car brake pedal, is easy to operate, has accurate positioning, and improves the testing efficiency.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
