[0019] The following is combined with Figure 1-7The utility model is described in further detail.
[0020] This embodiment discloses an electric pedal fatigue testing device. Figures 1 to 7 As shown, the utility model has the effect of facilitating the detection of the durability of automobile pedals, comprising a frame 1, with an upper rod 2 and a lower rod 3 arranged between the frame 1; a placement block 4 is fixedly arranged under the upper rod 2; a slider 5 is provided on the placement block 4; the slider 5 is fixedly connected to the movable plate 6; a cylinder 7 is fixedly provided at the bottom of the movable plate 6; a pressure block 8 is provided on the cylinder 7; an upper fixed plate 9 and a lower fixed plate 10 connected to the lower rod 3 are provided; a frame plate 11 is provided on the lower side of the lower fixed plate 10; an active rod 12 and a driven rod 13 are provided on the frame plate 11; one end of the active rod 12 is fixedly connected to the output shaft of the motor 14; one end of the driven rod 13 is connected to the frame plate 11; the other ends of the active rod 12 and the driven rod 13 are connected to the connecting rod 15; a pedal body 16 is fixedly provided on one end of the connecting rod 15.
[0021] By adopting the above technical solution: the two ends of the upper rod 2 and the lower rod 3 are fixedly connected to the frame 1 so that the upper rod 2 and the lower rod 3 are firmly arranged on the frame 1; when the durability test of the automobile pedal is carried out, the automobile pedal is fixedly connected to the connecting rod 15 and then the motor 14 is started to rotate the active rod 12 and then drive the connecting rod 15 to move, and the driven rod 13 plays a limiting role to prevent the connecting rod 15 from moving at will. When the active rod 12 rotates and the connecting rod 15 moves, the driven rod 13 also rotates; after the connecting rod 15 moves, the pedal body 16 is in an extended state, and after the cylinder 7 is started, the pressure plate is driven to move up and down, thereby simulating a person stepping on the automobile pedal through the pressure plate, thereby being able to test the durability of the automobile pedal; during the test, the pedal body 16 is always in an extended state, that is, Figure 1 As shown; two pedal bodies 16 can be provided on the upper rod 2 and the lower rod 3 so that the two pedal bodies 16 can be tested simultaneously, thereby improving the test efficiency.
[0022] like Figure 1 、 Figure 2 、 Figure 4 As shown, the placement block 4 is provided with a clamping plate 17 at both ends; the placement block 4 is provided with a slide groove 18; the slider 5 is provided on the slide groove 18; a reinforcement block 19 is provided on one side of the slide groove 18; the reinforcement block 19 has a threaded hole 20; the movable plate 6 has a threaded groove 21; and a first screw 22 is provided in the threaded hole 20 and the threaded groove 21.
[0023] By adopting the above technical solution: the card plate 17 can limit the displacement of the slider 5 and thus prevent the slider 5 from detaching from the slide groove 18, and the first screw 22 further improves the stability of the placement block 4 when connecting the threaded hole 20 and the threaded groove 21. When it is necessary to change the stepping position on the pedal body 16, the first screw 22 can be first unscrewed from the threaded hole 20 and the threaded groove 21, and then the slider 5 slides on the slide groove 18 to drive the cylinder 7 and the pressure block 8 to move. After the pressure block 8 moves to the position to be tested, the first screw 22 connects the threaded hole 20 and the other threaded groove 21 to make the cylinder 7 and the pressure block 8 firmly set, and then start the cylinder 7 to facilitate stepping tests at different positions of the pedal body 16.
[0024] like Figure 1 、 Figure 6 As shown, the upper fixing plate 9 and the lower fixing plate 10 are respectively located on both sides of the lower rod 3; a plate groove 23 is opened on the upper fixing plate 9; a plate hole 24 is provided on the lower fixing plate 10; a second screw 25 is provided on the plate groove 23 and the plate hole 24; a heightening block 26 is provided between the lower fixing plate 10 and the frame plate 11.
[0025] By adopting the above technical solution: the second screw 25 passes through the plate groove 23 and then connects to the plate hole 24 and then passes through the plate hole 24 so that the upper fixing block and the lower fixing block are firmly arranged on both sides of the lower rod 3, and the heightening block 26 can prevent the lower fixing plate 10 from contacting the frame plate 11.
[0026] like Figure 3 、 Figure 5 As shown, the output shaft of the motor 14 passes through one side of the active rod 12 and the bottom of the frame plate 11; the connecting rod 15 is connected to the active rod 12 and the driven rod 13 through the rotating rod 27; the motor 14 is fixedly connected to the frame body 1 through the cross bar 28.
[0027] By adopting the above technical solution: the output shaft of the motor 14 is connected to the active rod 12 so that the active rod 12 is driven to rotate by the rotation of the output shaft of the motor 14, and the output shaft of the motor 14 passes through the bottom of the frame 11 so that the output shaft of the motor 14 is firmly set; after the active rod 12 rotates, it drives the connecting rod 15 to move, thereby driving the pedal body 16 to move; the cross bar 28 makes the motor 14 and the frame 1 firmly set.
[0028] The frame 1 is provided with a control panel 29 and an electrical box 30 ; the bottom of the frame 1 is provided with supporting feet.
[0029] By adopting the above technical solution: the control panel 29 can control various mechanisms and display test information so that people can know the test information easily; the electrical box 30 supplies power to the motor 14 and cylinder 7 in the frame 1; the support feet make the experimental device stable.
[0030] In summary, the utility model has the following beneficial effects: when the durability test of the automobile pedal is carried out, the pedal body 16 is fixedly connected to the connecting rod 15 and then the motor 14 is started to rotate the active rod 12 and thereby drive the connecting rod 15 to move. The driven rod 13 acts as a limit to prevent the connecting rod 15 from rotating at will. When the pedal is extended, the driven rod 13 also rotates. After the connecting rod 15 moves, the pedal body 16 is in an extended state. After the cylinder 7 is started, it drives the pressure plate to move up and down, thereby simulating a person's stepping on the pedal body 16 through the pressure plate, and thus the durability of the pedal body 16 can be tested. Various parameters can be displayed on the control panel 29 to facilitate people to know the test information.
