Description

Technical Field

[0001] The utility model relates to the technical field of automobile carpet foot pad testing, in particular to an automobile carpet foot pad heel wear resistance testing device. Background Art

[0002] As people's living standards continue to improve, cars as a means of transportation have gradually become popular in every household. As an environmentally friendly car interior component that integrates four functions of water absorption, decontamination, sound insulation, and protection of the main carpet, car mats have almost become an indispensable part of the car. If the car carpet mats are not wear-resistant, the car mats will be damaged on the surface after long-term use, uncomfortable to use, and have a short service life.

[0003] In the existing technology, the wear resistance test of the carpet floor mat on the main driver's side is basically not performed. During driving, the driver uses the heel as a fulcrum and frequently switches between the accelerator pedal and the brake pedal, which accelerates the wear of the carpet floor mat on the main driver's side.

[0004] Therefore, a car carpet foot pad heel wear test device is designed to simulate the movement of the heel in real life and test the wear resistance of the foot pad under the action of the heel. Utility Model Content

[0025] Reference Figures 1 to 4 A car carpet foot pad heel wear test device comprises a test platform 1, a first support frame 2, a left and right motion part 3, a front and rear motion part 4, and a heel model 5. The test platform 1 is used to install the carpet foot pad. The first support frame 2 is rotatably connected to the test platform 1. The first support frame 2 is in an I-shape. The first support frame 2 is made of industrial aluminum profiles. The left and right motion parts 3 are arranged on the first support frame 2, the front and rear motion parts 4 are arranged on the left and right motion parts 3, and the heel model 5 is arranged on the front and rear motion parts 4. The left and right motion parts 3 simulate the switching action of the foot between the accelerator pedal and the brake pedal with the heel as the fulcrum. The front and rear motion parts 4 simulate the process of stepping on and releasing the brake or accelerator pedal with the heel as the fulcrum. The heel model 5 is preferably a steel heel model, and the width is preferably 75 mm (the radius is 37.5 mm), and the thickness is preferably 20 mm.

[0026] The left and right moving part 3 includes a second support frame 31 and a first cylinder 32. The second support frame 31 is rotatably connected to the first support frame 2. The second support frame 31 is in a right angle shape. The second support frame 31 is made of industrial aluminum profiles. The two ends of the first cylinder 32 are respectively connected to the first support frame 2 and the second support frame 31. Specifically, the two ends of the first cylinder 32 are connected by a cylinder connector 6 and a piston rod connector 7. Both the cylinder connector 6 and the piston rod connector 7 are movable to meet the adjustment of different distances. When the first cylinder 32 is actuated, it drives the right-angled second support frame 31 to perform left and right swinging motion with the position where the second support frame 31 is rotatably connected to the first support frame 2 as a pivot.

[0027] The front-to-back moving part 4 includes a third support frame 41 and a second cylinder 42. The third support frame 41 is rotatably connected to the second support frame 31. The third support frame 41 is in a straight line shape. The third support frame 41 is made of industrial aluminum profiles. The two ends of the second cylinder 42 are respectively connected to the third support frame 41 and the second support frame 31. Specifically, the two ends of the second cylinder 42 are connected by a cylinder connector 6 and a piston rod connector 7. When the second cylinder 42 is actuated, it drives the third support frame 41 to swing forward and backward with the rotationally connected portion of the third support frame 41 and the second support frame 31 as a pivot.

[0028] The following will refer to Figures 1 to 4 , the working principle of the utility model is explained.

[0029] Before the test, the wear-resistant test device is first lifted, and then the test sample 8 (foot pad and carpet) is placed on the test platform 1. After the test sample 8 is installed, the wear-resistant device is freely lowered, and the heel model 5 contacts the test sample 8. By controlling the first cylinder 32 and the second cylinder 42, the heel model 5 simulates two basic movements, namely, the rotation movement of the heel (simulating the conversion of the foot between the accelerator pedal and the brake pedal with the heel as the fulcrum) and the tilting movement of the foot (simulating the process of stepping on and releasing the brake or accelerator pedal with the heel as the fulcrum). When the first cylinder 32 is actuated, it drives the second support frame 31 to move. At this time, the second cylinder 42 does not actuate. The third support frame 41 moves with the movement of the second support frame 31, and then the heel model 5 set on the third support frame 41 starts to rotate left and right, simulating the switching action of the foot between the accelerator pedal and the brake pedal with the heel as the fulcrum; when the second cylinder 42 is actuated, it drives the third support frame 41 to swing back and forth with the position where the third support frame 41 is rotatably connected to the second support frame 31 as the pivot, and then the heel model 5 set on the third support frame 41 starts to tilt back and forth, simulating the process of stepping on and releasing the brake or accelerator pedal with the heel as the fulcrum. The test needs to be simulated 6000 times in total to test the wear resistance of the carpet foot pad under the action of the heel.

[0030] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
