[0028] The positioning assembly includes a fixed block 11 located on the connecting beam 7, one side of the fixed block 11 is slidably connected to the connecting beam 7 through a slider, the fixed block 11 is fixedly connected to a connecting seat, a circular hole is opened on the connecting seat, a positioning rod 13 is arranged in the circular hole, one end of the positioning rod 13 is connected to a handle 12, and the bottom of the connecting plate 10 is fixedly connected to a positioning pin 14 that cooperates with the positioning rod 13.
[0029] A supporting crossbeam 2 16 is passed between the tops of the two supporting long rods 5, and two groups of connecting blocks 2 are slidably connected to the supporting crossbeam 1 3. A connecting crossbeam 2 17 is arranged between one group of connecting blocks 2, and a test plate 18 is fixedly connected to one side of the connecting crossbeam 17 through a connecting piece, and a pressure sensor is arranged in the inner wall of the test plate 18.
[0030] A fixing seat 19 is fixedly connected to the test base plate 2 , an electric telescopic rod 20 is arranged on the inner wall of the fixing seat 19 , and an output end of the electric telescopic rod 20 passes through the fixing seat 19 and is connected to an L-shaped plate 21 .
[0031] An inclined plate 22 is fixedly connected to a corner of the L-shaped plate 21 close to the test plate 18 . An electric hydraulic rod 23 is provided on the inclined plate 22 . A tamping plate 24 is connected to the output end of the electric hydraulic rod 23 . The tamping plate 24 is located directly above the test plate 18 .
[0032] A slide groove is provided on the test bottom plate 2 , and a sliding block matching with the slide groove is fixedly connected to the bottom of the L-shaped plate 21 .
[0033] A protective mask 25 is fixedly connected to the top of the test base plate 2 .
[0034] In this embodiment, when the electric pedal needs to be tested, the electric pedal is first placed on the test flat plate 18, and then the connecting block 6 on the supporting short rod 4 and the supporting long rod 5 is slid according to the side inclination of the electric pedal. When the two connecting blocks 6 slide, the inclination angle of the connecting crossbeam 7 changes, so that the inclination angle of the connecting crossbeam 7 is tilted to match the side inclination of the electric pedal. At this time, one side of the electric pedal can be clamped into the groove of the rectangular clamping plate 15, and then the connecting plate 10 on the other side is moved toward the middle, so that the connecting plate 10 slides on the slide rail 9. When the connecting plate 10 moves, it drives the rectangular clamping plate 15 on it to move until the rectangular clamping plate 15 is The groove of the rectangular clamping plate 15 is embedded in the other side of the electric pedal, so that the electric pedal can be engaged. After the electric pedal is engaged in the groove, the handles 12 on both sides of the support plate 8 are then pulled in turn. When the handle 12 is pulled downward, the positioning rod 13 at the bottom of the handle 12 approaches the direction of the positioning pin 14 and is gradually inserted into the positioning pin 14, so that the positioning rod 13 can be positioned for the positioning pin 14. When the positioning rod 13 is inserted into the positioning pin 14, the movement of the connecting plate 10 is restricted. When the connecting plate 10 is fixed, the movement of the rectangular clamping plate 15 is restricted. Therefore, when the electric pedal is tested later, the electric pedal will be displaced.
[0035] Furthermore, when the electric pedal is fixed on the test plate 18, the electric telescopic rod 20 in the fixing seat 19 is started. When the electric telescopic rod 20 is in operation, it drives the L-shaped plate 21 to move toward the middle of the test base plate 2 until it moves to the front of the test plate 18. At this time, the electric hydraulic rod 23 on one side of the inclined plate 22 is started. When the electric hydraulic rod 23 is in operation, it drives the tamping plate 24 to move downward. When the tamping plate 24 moves downward to the test plate 18, pressure can be applied to the electric pedal on the test plate 18. The state of the electric pedal at different pressures can be obtained through the pressure sensor, and the situation of a person stepping on the electric pedal can be simulated, so as to perform a stepping test on the electric pedal and test the durability of the electric pedal.
