[0002] After the automotive electronic accelerator pedal is manufactured, its performance needs to be tested to ensure its stability. The testing process requires the use of a test fixture structure. However, the existing fixture structure often results in low testing accuracy due to the automotive pedal bracket not being securely fixed.

[0003] Patent CN210321501 U discloses a fixture structure for an automobile pedal bracket. The automobile pedal bracket to be tested is placed on a positioning plate, and one end is inserted into the positioning hole. By pressing the clamp, the clamping block is firmly fixed to one end of the automobile pedal bracket. Then, the telescopic cylinder is activated, which drives the clamping plate to work, so that the clamping plate is firmly pressed against the other side of the automobile pedal bracket. This can effectively ensure the stability of the automobile pedal bracket and effectively prevent the automobile pedal bracket from moving during the test, thus preventing the problem of low test accuracy.

Therefore, they should not be construed as limitations on the present application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] In a specific embodiment, this utility model provides the following technical solution: a test fixture structure for an automotive electronic throttle pedal, such as... Figures 1-5 As shown, the clamp structure facilitates the process of picking up and placing the pedal.

[0027] The base plate 1 and the support leg 2 at the lower end of the base plate 1 are provided; the upper end of the base plate 1 is provided with an operating plate 4 via a support rod 3, and the upper end of the operating plate 4 is provided with a placement groove 5 for placing a pedal. The upper end of the operating plate 4 is provided with a connecting protrusion 9, and the two ends of the connecting protrusion 9 are connected to a lifting plate 10. The upper end of the lifting plate 10 is provided with a locking plate 11 for placing a pedal. The lifting structure provided at the upper end of the operating plate 4 is used to control the automatic lifting and lowering of the pedal at the upper end of the locking plate 11. The protective structure provided at the upper end of the operating plate 4 is used to control the limiting force of the pedal.

[0028] The lifting structure includes a lifting screw 12. The lower end of the lifting plate 10 is provided with the lifting screw 12, and the rotating cylinder 13, which is threaded on the outer side of the lifting screw 12, is rotatably installed on the upper end of the support base plate 1. The rotation of the rotating cylinder 13 can drive the lifting screw 12 to move up and down.

[0029] A limiting member 25 is fixedly installed at the lower end of the operating plate 4, and two sets of driving racks 16 are slidably installed inside the limiting member 25. The two sets of driving racks 16 are meshed with the rotating gear 14 fixedly installed on the outside of the rotating cylinder 13. The driving racks 16 drive the rotating cylinder 13 to rotate through the rotating gear 14.

[0030] A connecting rod 15 is fixedly installed at the end of the drive rack 16 away from the rotating gear 14, and the connecting rod 15 is slidably connected to the operation plate 4. The power for driving the rack 16 is provided by the positioning clamp 8 at the upper end of the connecting rod 15.

[0031] When using this test fixture structure for automotive electronic accelerator pedals, it is necessary to first power the internal electrical equipment of the structure via an external power source. Then, the pedal can be clamped and limited by the fixture. During this process, the drive motor 6 drives the bidirectional screw 7 to rotate, causing the two sets of positioning clamps 8 to move closer together. The movement of the positioning clamps 8 will cause the drive rack 16 to slide inside the limiting member 25 via the connecting rod 15. Furthermore, the movement of the drive rack 16 will drive the rotating gear 14 meshed with it to rotate. The rotation will cause the rotating cylinder 13 to rotate and the internal threaded lifting screw 12 to move down. At this time, the lifting screw 12 will drive the clamping plate 11 to move up through the lifting plate 10, so that the pedal at the upper end of the clamping plate 11 enters the interior of the placement groove 5. This facilitates the two sets of positioning clamps 8 to limit and clamp the pedal. The pedal can be placed directly on the upper end of the clamping plate 11 by the robotic arm for easy picking and placing. This completes the quick picking and placing process of the pedal by the fixture. By automatically placing the pedal inside the placement groove 5, the efficiency of the fixture in detecting the pedal can be effectively improved.

[0032] In one specific embodiment, such as Figures 1-6 As shown, in order to solve the problem that it is difficult to control the clamping force when the existing clamp is used to hold the pedal, the process of controlling the clamping force of the clamp on the pedal by the new clamp is disclosed.

[0033] The protective structure includes a positioning clamp 8, which is slidably disposed on the upper end of the operating plate 4. The two sets of positioning clamps 8 are provided with clamping grooves 17 at their close ends. Meanwhile, the lower end of the positioning clamp 8 is fixedly connected to the upper end of the connecting rod 15. The pedal is clamped by the clamping grooves 17 through the movement of the two sets of positioning clamps 8.

[0034] The upper end of the operation plate 4 is equipped with a drive motor 6, and the output end of the drive motor 6 is equipped with a bidirectional screw 7 that is threadedly connected to two sets of positioning clamps 8. The positioning clamps 8 are slidably connected to the guide rod 22 at the upper end of the operation plate 4. The two sets of positioning clamps 8 slide on the outside of the guide rod 22 to complete the limiting movement process of the guide rod 22.

[0035] A positioning slide plate 18 is slidably installed inside the clamping groove 17, and a telescopic rod 19 is fixedly installed at one end of the positioning slide plate 18 near the clamping groove 17. The end of the telescopic rod 19 away from the positioning slide plate 18 is fixedly connected to the contact plate 21 inside the clamping groove 17. Meanwhile, a return spring 20 is sleeved on the outside of the telescopic rod 19. The clamping force of the positioning slide plate 18 on the pedal can be controlled by the pressure transmission between the positioning slide plate 18 and the contact plate 21.

[0036] When using this test fixture structure for automotive electronic throttle pedals, the two sets of positioning clamps 8 need to be brought close together and clamped at both ends of the pedal using the clamping groove 17. During this process, the positioning slide plate 18 needs to contact the two ends of the pedal. At this time, the positioning slide plate 18 can be used for limiting clamping. During the clamping process, the positioning slide plate 18 will slide inside the clamping groove 17, causing the telescopic rod 19 and the return spring 20 to retract. At this time, the contact plate 21 will be subjected to the pressure of the return spring 20 and transmit the pressure to the pressure sensing device 23. The pressure sensing device 23 will receive the signal and transmit it to the control device 24, so that the control device 24 can receive the signal and control the working state of the drive motor 6 (the working principle of the control device 24 and the pressure sensing device 23 is existing technology and will not be elaborated here). This allows the drive motor 6 to control the rotation and stop of the lifting screw 12, avoiding excessive pressure on the pedal from the two sets of positioning clamps 8, which could damage the pedal and affect the test results. By setting an elastic structure to limit clamping the pedal, the controllability of the pedal clamping can be ensured and the pedal can be protected.

[0037] Based on the above embodiments, such as Figures 1-6 The process of using the clamp to limit pedals of different sizes is shown in the figure.

[0038] When using this test fixture structure for automotive electronic throttle pedals, the pedal needs to be positioned and clamped by two sets of positioning clamps 8. By controlling the distance between the two sets of positioning clamps 8, pedals of different sizes can be clamped and limited. At the same time, two sets of snap-fit ​​plates 11 are provided at the upper end of the operating plate 4, which can simultaneously perform limit detection on two sets of pedals, effectively improving the efficiency of the fixture structure in pedal detection and increasing the overall practicality.
