[0001] The invention belongs to the technical field of automobile parts testing equipment and relates to a threshold pedal assembly durability testing equipment. Background Art

[0002] The threshold pedal assembly is a component of a car. Currently, the threshold pedal assemblies of some cars are movable. For example, some SUVs or off-road vehicles and other cars are equipped with electric retractable pedals. The threshold pedal automatically extends when the door is opened and automatically retracts when the door is closed, or the threshold pedal is automatically extended or retracted by sensing.

[0003] This type of threshold pedal is more intelligent and more convenient to use, but the quality requirements of this type of threshold pedal are relatively high, and the durability of the threshold pedal assembly needs to be tested during the production process.

[0004] Currently, there is a lack of equipment capable of performing durability tests on threshold pedal assemblies, so the quality of threshold pedal assemblies cannot be controlled during automobile production. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to provide a threshold pedal assembly durability test device.

[0006] The object of the present invention can be achieved by the following technical solutions: A threshold pedal assembly durability test device, comprising:

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figure 1-7 As shown, a threshold pedal assembly durability test device includes: a pedal mechanism 100 and a measuring mechanism 400. The pedal mechanism 100 can step on the threshold pedal during the test to simulate the actual stepping effect. The measuring mechanism 400 can detect the deformation of the threshold pedal when stepped on, and the pedal mechanism 100 can also be stepped on repeatedly.

[0035] The pedaling mechanism 100 includes a fixed bracket 200 and at least one group of test units 300, wherein the test unit 300 includes a first mounting bracket 310, a first driving element 320 and a pedaling assembly 330, wherein the first mounting bracket 310 is movably connected to the fixed bracket 200, the first driving element 320 is connected to the first mounting bracket 310, the pedaling assembly 330 is linked to the first driving element 320, and the first driving element 320 can drive the pedaling assembly 330 to step on the threshold pedal assembly.

[0036] Preferably, the fixing bracket 200 is similar to a gantry structure, and the number of the test units 300 can be set to two or more groups, so that different positions of the threshold pedal can be tested at the same time, and the efficiency of simulated stepping is higher.

[0037] The first mounting bracket 310 can move on the fixed bracket 200 to select the stepping position, and the first driving element 320 can drive the stepping assembly 330 to move up and down, and apply a set pressure to the stepping assembly 330. During the test, the first driving element 320 drives the stepping assembly 330 to move toward the car threshold pedal, and then steps on the car threshold pedal with a certain pressure. The first driving element 320 can set the number of times and the stepping time of the stepping assembly 330, so that the stepping assembly 330 can simulate various stepping conditions more accurately and effectively.

[0038] The measuring mechanism 400 includes a measuring element 410 . The measuring element 410 is disposed below the pedal assembly 330 , and the measuring element 410 is used to measure the deformation of the threshold pedal assembly.

[0040] like Figure 1-4 As shown, on the basis of the above-mentioned embodiment, in order to facilitate testing, the device also includes a body support seat 500 for positioning and supporting the automobile body, the fixing bracket 200 is fixed to the side of the body support seat 500, and the position of the threshold pedal of the vehicle body is just located at the side of the body support seat 500. The fixing bracket 200 is fixedly set on the side of the body support seat 500, so that the pedal mechanism 100 and the measuring mechanism 400 are close to the position of the threshold pedal, and the body of the automobile is fixed on the body support seat 500, so that it can be conveniently detected through the pedal mechanism 100 and the measuring mechanism 400.

Preferably, the pedal pressure needs to be controlled during the test, so the pressure sensor 340 is required to detect the pedal pressure of the pedal assembly 330 to ensure the accuracy of the test pressure.

[0042] Specifically, when the first driving element 320 drives the pedal assembly 330 downward, the pressure sensor 340 can detect the pedal pressure and feed it back to the control system.

[0044] Preferably, the first driving element 320 can drive the test pressure block 331 to apply pressure to the threshold pedal, and the pedal pad 332 is in contact with the threshold pedal, thereby achieving a buffering effect to prevent the test pressure block 331 from crushing or damaging the threshold pedal, and the test pressure block 331 is hinged to the pressure sensor 340, so the test pressure block 331 is rotatable, which can fit the angle of the threshold pedal and better simulate the stepping effect.

[0045] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, on the basis of the above embodiment, the test unit 300 also includes a lifting seat 350, a nut block (not shown in the figure), a screw rod 360 and a second driving element 370, the lifting seat 350 is movably connected to the first mounting bracket 310, the screw rod 360 is rotatably connected to the first mounting seat, the nut block is linked to the screw rod 360, the lifting seat 350 is fixedly connected to the nut block, the first driving element 320 is fixedly connected to the lifting seat 350, the second driving element 370 is connected to the screw rod 360 and can drive the screw rod 360 to rotate, and when the screw rod 360 rotates, the first driving element 320 can be driven to move through the lifting seat 350.

[0046] Preferably, the height positions of the first driving element 320 and the pedal assembly 330 are adjustable, so that better pedaling can be performed. When the initial distance between the threshold pedal and the pedal assembly 330 is too far, the first driving element 320 and the pedal assembly 330 can be raised, and vice versa. This allows for more flexible adjustment of the position of the test unit 300.

[0047] The lifting structure includes a lifting seat 350, a nut block, a screw rod 360 and a second driving element 370. The nut block and the screw rod 360 can achieve a linear driving effect through an external thread and a threaded hole structure, and the lifting block is connected to the nut block, so when the screw rod 360 rotates, it can drive the lifting seat 350 to move up and down, thereby adjusting the height position of the first driving element 320 and the pedal assembly 330.

[0048] Preferably, in order to better drive the screw rod 360 to rotate, the screw rod 360 can be driven to move by the second driving element 370, and the second driving element 370 can be set as a hand wheel or a motor, so that it can be adjusted manually or automatically.

[0051] It should be supplemented that a rail clamp may be provided on the first mounting bracket 310 so that the first mounting bracket 310 is fixed on the linear guide rail 220 to prevent the test unit 300 from moving during testing.

[0057] like Figure 1 As shown, on the basis of the above embodiment, the column 230 is sequentially provided with a plurality of height adjustment holes 231 along its height direction, and the crossbeam 210 is connected to the height adjustment holes 231 by bolts. Preferably, the installation height of the crossbeam 210 is also adjustable, and the crossbeam 210 can be connected to any group of height adjustment holes 231, thereby greatly adjusting the height position of the pedal mechanism 100.
