[0002] Chinese patent CN206945834U discloses a device for detecting the telescopic performance of an automobile electric step. Distance sensors are set at both ends of the path of extension and retraction of the electric step to detect the telescopic distance of the electric step. The timing and calculation of the micro-control elements in the control cabinet are then used to detect the degree of activation of the electric step within a specified time to test the sensitivity of the electric step. This can effectively improve the efficiency of detecting the telescopic performance of the electric step, save labor costs, and the detection results are accurate with small errors.

DETAILED DESCRIPTION

[0018] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0019] Example 1

[0020] The automotive electric pedal test bench includes a frame 1 formed by connecting and securing I-beams, U-shaped steel, and pipes. Specifically, frame 1 comprises an upper mounting frame 2 and a lower base 3, which are connected and secured by a connecting frame. A fixing frame 4 is provided at the bottom of mounting frame 2, on which a mounting seat 5 is mounted. Mounting seat 5 is used to connect and secure the pedal assembly to the driving and driven assemblies. Mounting frame 2 also includes a pressure unit and a slide rail 6. A pressure sensor is provided at the contact end of the pressure unit. This structural design allows the position of the cylinder's action point to be varied, thereby testing the strength at different locations.

[0021] Next, the mounting frame 2 includes a first U-shaped steel 7, which is provided with a rack 8. The pressure unit includes an upper transmission unit 10 and a lower pressure cylinder 11. The pressure cylinder 11 and the transmission unit 10 are connected by a connecting seat 12, which is mounted on the slide rail 6. The transmission unit 10 is connected to a transmission gear 9. The transmission gear 9 and the rack 8 are engaged to drive the pressure cylinder 11 to move along the rack 8. The gear rack 8 transmission has the advantages of reliable transmission and controllable position.

[0022] The piston rod of the pressure cylinder 11 is connected to a pressure block 21, on which a pressure sensor is provided, and the pressure block 21 and the piston rod are connected via a pin, thereby ensuring that the pressure block 21 can fit tightly against the pedal surface.

[0023] In order to ensure that the transmission unit 10 that drives the transmission gear 9 will not be deflected by force during the operation of the pressure cylinder 11, the connecting base 12 also includes a second guide rail 13. The second guide rail 13 is composed of two sets of second guide rails 13, which are respectively mounted on the top of the two side plates of the first U-shaped steel 7. The transmission unit 10 is a transmission motor.

[0024] Next, the second U-shaped steel 14 has a slot 15 on its bottom plate. The mounting base 5 includes a horizontal plate 16 and mounting legs 20 extending from the bottom end of the horizontal plate 16. Vertical vertical plates 17 extend from both sides of the horizontal plate 16. The vertical plates 17 are fitted with the side plates of the second U-shaped steel 14. The front and rear side plates of the second U-shaped steel 14 are both provided with strip-shaped connecting holes 18. The vertical plates 17 are provided with fixing holes 19 and fixing bolts. The fixing bolts pass through the connecting holes 18 of the front side plate, the fixing holes 19 of the front and rear vertical plates 17, and then pass through the connecting holes 18 of the rear side plate and are fixedly connected by the fixing bolts. This structural design ensures that when adjusting the position of the mounting base 5, the mounting base 5 does not need to be disassembled separately, and only needs to be moved. Obviously, the horizontal plate 16 presses on the bottom plate, and the mounting legs 20 extend from the slot 15.

[0025] Example 2

[0026] In this embodiment, the second guide rail 13 in embodiment 1 is a plastic wheel or a rubber wheel.

[0027] Example 3

[0028] In this embodiment, a scale bar is provided on the outside of the side plate of the second U-shaped steel 14 .
