Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and more specifically, to a dual-station pedal testing device. Background Technology

[0002] The foot pedals on both sides of a car are core components of vehicle convenience features, and their performance and stability directly affect the user's experience of getting in and out of the car and the safety of use.

[0003] The automotive pedal assembly consists of pedals located on both sides of a vehicle for getting in and out. It comprises a pedal panel, a main bracket, and a secondary bracket, both mounted on the bottom of the vehicle. The main bracket houses a drive motor; when a user gets in or out, the drive motor extends the pedal panel, and when the door closes, the drive motor retracts the pedal panel back to the bottom of the vehicle. Currently, testing equipment for this type of retractable side pedal has several shortcomings. First, most equipment only supports single-pedal testing, unable to process multiple workpieces simultaneously, resulting in long testing cycles in mass production scenarios, making it difficult to match production line pace. Second, electrical parameter testing, gap measurement, and anti-pinch testing are mostly performed by independent equipment, requiring manual workpiece transfer, which is cumbersome and prone to human error.

[0004] These problems make it difficult for existing testing equipment to meet the high-quality production requirements of the automotive industry for side pedal components in terms of testing accuracy, efficiency, and adaptability. Therefore, there is an urgent need to design a dual-station, highly integrated, and highly accurate pedal testing equipment to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the technical problem of low detection efficiency caused by low integration of existing detection equipment.

[0006] To address the aforementioned problems, this invention provides a dual-station pedal testing device for testing pedal assemblies composed of a pedal panel, a main support, and a secondary support. The device includes a workbench with symmetrically arranged flip-up tables on its upper surface, and symmetrically mounted fixing plates on the surface of the flip-up tables. It further includes: a fixing module disposed on the surface of the fixing plates for fixing the main support and secondary support portions of the pedal assembly to the fixing plate surface; a displacement sensor disposed on the fixing plate for detecting the displacement distance when the pedal panel is unfolded and retracted; a rotation drive module disposed on the workbench surface for driving the flip-up tables to rotate; and an anti-pinch testing module disposed in the workbench for testing the anti-pinch capability of the pedal assembly after the rotation drive module drives the flip-up tables to rotate.

[0007] The dual-station pedal testing device provided by this invention has, but is not limited to, the following beneficial effects compared to the prior art: To address the low efficiency issues caused by the low integration of existing testing equipment, this new device first places the main and auxiliary supports of the pedal assembly into the contouring fixture of the tilting table during testing. These supports are then quickly secured using a fixing module. The symmetrically arranged tilting tables on the worktable surface enable a dual-station design, supporting simultaneous or independent testing of two pedal assemblies. Once the pedal assembly is secured, the drive motor in the main support unfolds and retracts the pedal panel, with displacement sensors collecting real-time displacement data. Simultaneously, a rotation drive module rotates the tilting table to the testing position, and the drive motor in the main support again unfolds the pedal panel until it contacts the anti-pinch testing module, triggering automatic retraction. By capturing the resistance force exerted by the pedal panel on the anti-pinch testing module, the anti-pinch capability of the pedal assembly is tested. This device integrates electrical parameter detection, gap measurement, and anti-pinch testing functions, effectively achieving one-stop testing. The testing process eliminates the need for frequent workpiece transfer, significantly improving testing efficiency and resulting in superior performance.

A second adjusting block is fixedly disposed on the lower surface of the first adjusting block, and a second slide rail is movably disposed in the second adjusting block. An anti-pinch test mechanism is disposed at the bottom of the second slide rail.

[0012] Furthermore, the anti-pinch testing mechanism includes a support plate fixedly installed at the bottom of the second slide rail. A fourth cylinder is fixedly installed at the bottom of the support plate, and the telescopic end of the fourth cylinder passes through the support plate. A stop assembly is fixedly installed at the telescopic end of the fourth cylinder to prevent stepping on the panel.

[0013] Furthermore, the gear shifting assembly includes a lifting block fixedly installed on the telescopic end of the fourth cylinder, a stop block movably installed on the side wall of the lifting block, and a pressure sensor is provided between the stop block and the lifting block.

It is connected to the servo motor, the first cylinder, the second cylinder, the third cylinder, the fourth cylinder, the displacement sensor, and the pressure sensor through Profinet communication. It has a built-in PLC and detection software for equipment control, parameter setting, data acquisition, curve plotting, and test result archiving. Attached Figure Description

[0027] See Figures 1-8This invention discloses a dual-station pedal testing device for testing a pedal assembly 2 composed of a pedal panel 21, a main support 22, and a secondary support 23. The device includes a workbench 1, with a symmetrically arranged flipping platform 3 on the upper surface of the workbench 1, and a symmetrically mounted fixing plate 4 on the surface of the flipping platform 3. The device further includes: a fixing module 5 disposed on the surface of the fixing plate 4, used to fix the main support 22 and the secondary support 23 of the pedal assembly 2 to the surface of the fixing plate 4; a displacement sensor 6 disposed on the fixing plate 4, used to detect the displacement distance of the pedal panel 21 when it unfolds and retracts; a rotation drive module 8 disposed on the surface of the workbench 1, used to drive the flipping platform 3 to rotate; and an anti-pinch test module 7 disposed in the workbench 1, used to test the anti-pinch capability of the pedal assembly 2 after the rotation drive module 8 drives the flipping platform 3 to rotate.

[0028] In this embodiment, addressing the technical problem of low detection efficiency caused by low integration in existing testing equipment, this device, during testing, first places the main support 22 and the secondary support 23 of the pedal assembly 2 into the contouring fixture of the tilting table 3, and quickly fixes them with the help of the fixing module 5. Furthermore, the tilting tables 3 on the surface of the worktable 1 are symmetrically arranged, achieving a dual-station design that supports simultaneous or independent testing of two pedal assemblies 2. After the pedal assembly 2 is fixed, the drive motor in the main support 22 can drive the pedal panel 21 to unfold and retract. The displacement sensor 6 can collect the displacement data of the pedal panel 21 in real time. Simultaneously, the rotary drive module 8 can drive the tilting table 3 to rotate to the test position, and the drive motor in the main support 22 can drive the foot panel 21 to unfold. After the foot panel 21 comes into contact with the anti-pinch test module 7, the foot panel 21 will automatically retract. By capturing the resistance force applied by the foot panel 21 to the anti-pinch test module 7, the anti-pinch capability of the pedal assembly 2 can be tested. This equipment integrates electrical parameter detection, gap measurement, and anti-pinch testing functions, effectively realizing one-stop testing. During the testing process, there is no need to frequently transfer the workpiece, which greatly improves the testing efficiency and the effect of use is better.

[0029] Optional, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6The fixing module 5 includes a fixing seat 51 fixedly installed on the upper surface of the fixing plate 4. A first cylinder 52 is symmetrically installed on the inner walls of both sides of the fixing seat 51. The telescopic end of the first cylinder 52 passes through the fixing seat 51, and a moving block 53 is fixedly installed on the telescopic end of the first cylinder 52. A second cylinder 54 is fixedly installed on the upper surface of the moving block 53, and a lifting plate 55 is fixedly installed on the telescopic end of the second cylinder 54. A first clamping block 56 is fixedly installed on the lower surface of the lifting plate 55 for supporting the upper surfaces of the main support 22 and the auxiliary support 23. The upper surface of the fixing plate 4 is also provided with a secondary abutment assembly for cooperating with the first clamping block 56 to form a three-point locking position for the main support 22 and the auxiliary support 23. The secondary abutment assembly includes a mounting seat 57 inclinedly set on the upper surface of the fixing plate 4, and a third cylinder 58 is fixedly installed in the mounting seat 57. A clamping plate 59 is fixedly installed on the telescopic end of the third cylinder 58, and a second clamping block 510 is fixedly installed on the lower surface of the clamping plate 59.

[0030] In this embodiment, after the workpiece is placed, the first cylinder 52 extends and retracts to drive the moving block 53 to move to the designated position, and the second cylinder 54 extends and retracts to drive the lifting plate 55 to move down. The first clamping block 56 at the bottom of the lifting plate 55 abuts against the upper surface of the main support 22 and the secondary support 23. At the same time, the tilt angle of the mounting base 57 matches the support contour of the main support 22 and the secondary support 23, ensuring that the second clamping block 510 can accurately abut against the side of the support. The third cylinder 58 extends and retracts to drive the second clamping plate 59 to move. The second clamping block 510 and the first clamping block 56 work together to apply clamping force to the main support 22 and the secondary support 23 from different directions, forming a stable three-point locking position, dispersing the clamping stress, and avoiding deformation of the support. The three-point locking position has better vibration resistance than the two-point fixing position, ensuring that there is no loosening of the workpiece during the testing process, and the use effect is better.

[0031] Optional, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The ends of the main bracket 22 and the auxiliary bracket 23 are located between the second clamping block 510 and the mounting base 57, and when the ends of the main bracket 22 and the auxiliary bracket 23 are in contact with the mounting base 57, their bottoms are parallel to the surface of the fixed base 51.

[0032] In this embodiment, the end of the bracket is located between the second clamping block 510 and the mounting base 57. The mounting base 57 provides a positioning reference surface for the bracket. When the second clamping block 510 applies clamping force, the end of the bracket is in close contact with the mounting base 57, ensuring that the bottom of the bracket is parallel to the surface of the fixed base 51, thereby ensuring that the horizontal part of the bracket is stably clamped between the fixed base 51 and the first clamping block 56, ensuring clamping stability.

[0033] Optional, please refer to Figure 7 and Figure 8The anti-pinch test module 7 includes a first slide rail 77 disposed in the workbench 1, and a first adjusting block 78 is movably disposed on the outer side of the first slide rail 77.

An anti-pinch test mechanism is disposed at the bottom of the second slide rail 79.

[0034] In this embodiment, according to the size of different models of pedal assembly 2, the locking bolt is loosened, the position of the first adjusting block 78 is adjusted along the first slide rail 77 (X direction), and the position of the anti-pinch test mechanism is adjusted along the second slide rail 79 (Y direction) so that the anti-pinch test mechanism is accurately aligned with the movement trajectory of the pedal panel 21. After the adjustment is completed, the locking bolt is tightened to ensure the accuracy of the anti-pinch test.

[0035] Optional, please refer to Figure 7 and Figure 8 The anti-pinch testing mechanism includes a support plate 71 fixedly installed at the bottom of the second slide rail 79.

A stop block 75 is movably installed on the side wall of the lifting block 74, and a pressure sensor 76 is provided between the stop block 75 and the lifting block 74.

[0036] In this embodiment, during the anti-pinch test, the fourth cylinder 72 extends and drives the gear assembly to rise to a preset height, blocking the retraction path of the foot panel 21; when the foot panel 21 retracts, it contacts the stop block 75, the fourth cylinder 72 remains in a fixed position, and the pressure sensor 76 collects the contact force value to realize the anti-pinch performance detection; after the test is completed, the fourth cylinder 72 drives the gear assembly to descend and reset.

[0037] Optional, please refer to Figure 7 and Figure 8 The lower surface of the lifting block 74 is also fixedly installed with a limiting rod 73, and the limiting rod 73 passes through the support plate 71.

[0038] In this embodiment, the limiting rod 73 is made of stainless steel, and there are two rods in total. They are symmetrically distributed on both sides of the fourth cylinder 72, passing through the guide hole of the support plate 71, and the end is provided with a limiting nut. When the fourth cylinder 72 drives the lifting block 74 to rise and fall, the limiting rod 73 slides along the guide hole of the support plate 71 to limit the rotation and offset of the lifting block 74, ensuring that the stop block 75 is always in a vertical state, and making the up and down movement of the lifting block 74 more stable.

[0039] Optional, please refer to Figure 2 and Figure 3The rotary drive module 8 includes an ear seat 81 fixedly installed on the upper surface of the worktable 1.

The upper surface of the worktable 1 is also fixedly installed with a servo motor 83, and the drive end of the servo motor 83 is connected to the rotating shaft 82.

[0040] In this embodiment, the ear seats 81 are made of cast iron and are symmetrically distributed; the rotating shaft 82 is made of 45# steel with heat treatment and a rotational clearance ≤0.02mm; the servo motor 83 is a Huichuan series servo motor equipped with a planetary reducer (reduction ratio 1:10), and the drive end is connected to the rotating shaft 82 through a flexible coupling; during testing, the servo motor 83 receives control commands and drives the rotating shaft 82 to rotate, causing the tilting table 3 to rotate from the loading / unloading position to the testing position; after the test is completed, the servo motor 83 rotates in the opposite direction, causing the tilting table 3 to reset to the loading / unloading position, facilitating manual handling of workpieces; the precise control of the servo motor 83 ensures that the rotation angle accuracy of the tilting table 3 is ±0.01°, which is 90% higher than that of the stepper motor drive; the flexible coupling compensates for installation errors, reduces vibration, and ensures that the tilting table 3 runs smoothly with a noise level ≤60dB; it is adaptable to different testing rhythms; the rigid design of the ear seats 81 and the rotating shaft 82 ensures that the tilting table 3 has a load-bearing capacity ≥50KG, meeting the testing requirements of the heavy-duty pedal assembly 2.

[0041] Optional, please refer to Figure 1 and Figure 7 Above the workbench 1, there is also a control and display integrated machine 9. The control and display integrated machine 9 is fixedly installed in the center of the workbench 1 by a bracket. It is connected to the servo motor 83, the first cylinder 52, the second cylinder 54, the third cylinder 58, the fourth cylinder 72, the displacement sensor 6 and the pressure sensor 76 through Profinet communication. It has a built-in PLC and detection software for equipment control, parameter setting, data acquisition, curve plotting and test result archiving.

[0042] In this embodiment, the integrated control and display unit 9 serves as the core of the equipment's control and data processing. It sends action commands to the servo motor 83, the first cylinder 52, the second cylinder 54, the third cylinder 58, and the fourth cylinder 72 via the Profinet bus, and sends acquisition commands to the displacement sensor 6 and the pressure sensor 76. It receives data transmitted from each sensor in real time and displays it dynamically on the touch screen. It plots current curves and force curves using software algorithms, automatically determines whether the test results are qualified, and archives them in Excel format to a designated path. It supports password protection to prevent accidental modification of parameters.

[0043] The specific testing process is as follows: First, connect the power and air supply, stabilize the air supply pressure at 0.6MPa, start the integrated control and display unit 9, enter the password to log in to the system, and retrieve the test formula parameters for the corresponding vehicle model; manually place the two pedal assemblies 2 into the contouring fixtures of the two flip tables 3, with the bracket fixed surface facing down and the pedal panel 21 facing up; press the start button, and the first cylinder 52, the second cylinder 54, and the third cylinder 58 will act sequentially, using the first clamp 56 and the second clamp 510 to lock the main bracket 22 and the auxiliary bracket 23 in three-point position; manually connect the pedal motor power harness, press the test button, and the pedal will connect to the ECU to perform an opening and closing calibration program, with the pedal performing one unfolding and one retraction, resetting to the initial state; the equipment will then start testing electrical parameters (voltage, current, opening and closing time). During the test, displacement sensor 6 collects displacement data of pedal panel 21 in real time and records height values ​​under multiple opening and closing states. After electrical parameter detection, rotary drive module 8 drives tilting table 3 to flip, pedal panel 21 unfolds, and fourth cylinder 72 drives gear assembly to rise to preset height. Pedal panel 21 contacts stop block 75 and retracts. Pressure sensor 76 collects force data in real time and transmits it to control and display integrated machine 9.

[0045] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
