Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts testing, in particular to an automobile pedal performance testing tool. Background Art

[0002] Cars are a common means of transportation in our daily lives. Cars are divided into different types according to their different uses. SUVs, MPVs and other models have higher chassis, which makes it inconvenient to get on the car. For this reason, pedals are installed under the chassis of the car to assist passengers in getting into the car. After the car pedals are produced, they need to be tested to ensure their stability during use, and test tooling will be used.

[0003] A Chinese patent with the existing publication number CN116337483B discloses an automobile pedal performance testing device, which includes a mounting assembly, a pedal assembly, and a testing assembly. The detection seat is controlled to move up and down by a lifting column, and a load is applied to the pedal by a pressure block to test the load-bearing capacity of the pedal. At the same time, the stability of the pedal is tested by changing the contact point between the pressure block and the pedal.

[0004] During use, the above-mentioned technical solution requires applying pressure to the surface of the pedal through a transformer block to test the pedal's pressure resistance. However, in actual use, the passenger's feet are usually wearing shoes and stepping on the top of the pedal. Therefore, when pressing down, the pedal is pressed down with one surface, and the transformer block presses down the pedal through the contact point. The contact area is small and the pressure is large, which is different from the actual usage situation and will affect the test results.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0039] like Figures 1 to 5 As shown, an automobile pedal performance test tool according to an embodiment of the present invention includes a device housing 1, a mounting plate 11 fixed to one side of the device housing 1, an electric telescopic rod 12 disposed above the device housing 1, a pressure sensor 13 mounted at the bottom end of the electric telescopic rod 12, a test box 3 mounted at the bottom end of the pressure sensor 13, an electric pedal 2 mounted at the bottom end of the mounting plate 11, and a motor integrated in the electric pedal 2 capable of driving the pedal body of the electric pedal 2 to extend below the test box 3;

[0040] Both sides of the test box 3 are rotatably connected with extension plates 31, and a second motor 36 is installed inside the test box 3;

[0041] During the test, the second motor 36 drives the extension plate 31 to expand from both sides of the test box 3 to increase the contact area between the test box 3 and the pedal body of the electric pedal 2;

[0042] The electric pedal 2 needs to be tested after production. The test can tell the load range of the electric pedal 2. By comparing the load range of the standard electric pedal 2, it can be known whether the current electric pedal 2 is qualified. During the test, the installation part of the electric pedal 2 to be tested is installed on the bottom of the mounting plate 11 through the installation tool, and then the control line of the electric pedal 2 is connected to the controller of the device housing 1. At this time, press the button on the controller to control the motor of the electric pedal 2 to drive the pedal of the electric pedal 2 to unfold. Then the test can be carried out, and the electric telescopic rod 12 is started to push the pressure sensor 13 downward. The pressure sensor 13 drives the test box 3 to move downward. At this time, the test box 3 presses down on the top of the electric pedal 2. At the same time, the pressure sensor 13 records the current pressure value in real time and transmits it to the controller. The controller can display the current pressure value. During the test, the electric telescopic rod 12 is continuously pushed downward. When the pressure value of the pressure sensor 13 reaches the maximum value of the preset standard range of the preliminary test, the electric telescopic rod 12 is stopped from continuing to press downward, and the electric telescopic rod 12 is started to drive the pressure sensor 13 to rise. The pressure sensor 13 also drives the test box 3 to rise. At this time, the test box 3 is separated from the top of the electric pedal 2. At this time, the preliminary test of the electric pedal 2 can be completed. The staff observes whether the test area is deformed and starts the electric pedal 2 to test whether the pedal can be retracted normally. After the pedal is retracted, the electric pedal 2 is controlled to extend the pedal again. At this time, the preliminary test is completed. The bottom surface of the test box 3 is directly pressed on the top of the electric pedal 2 to simulate the surface contact of the foot on the top of the electric pedal 2. The test environment is closer to reality. In the preliminary test, the downward pressure value of the electric telescopic rod 12 is set to a range that matches the child's weight.

[0043] After the preliminary test, the next test needs to be carried out. After the test box 3 is raised, the second motor 36 is started to drive the extension plates 31 on both sides of the test box 3 to rotate. In the initial state, the extension plates 31 are attached to both sides of the test box 3. When the extension plates 31 are driven to rotate, the extension plates 31 rotate from the side of the test box 3 to the bottom of the test box 3. After the extension plates 31 rotate to the extreme position, the second motor 36 stops rotating. At this time, the extension plates 31 on both sides are flush with the bottom surface of the test box 3. The extension plates 31 can increase the bottom area of ​​the test box 3. At this time, starting the electric telescopic rod 12 drives the test box 3 to push downward through the pressure sensor 13, so that the test box 3 can be pressed down on the top of the electric pedal 2 again, and the extension plates 31 will also be pressed on the electric pedal 2 At the top, in this test, the pressure value of the electric telescopic rod 12 is set to a range that matches the weight of an adult. At this time, the electric telescopic rod 12 continues to press down the pressure sensor 13 until the preset standard range for further testing is reached. The electric telescopic rod 12 stops pressing down. At this time, the electric telescopic rod 12 drives the pressure sensor 13 and the test box 3 to rise, and then the second motor 36 rotates in the opposite direction to drive the extension plate 31 to reset. At this time, the staff observes whether the test area is deformed again, and at the same time starts the electric pedal 2 to test whether the pedal can be retracted normally. At this time, all tests can be completed. After the test, the electric pedal 2 can be removed from the bottom end of the mounting plate 11. In this way, the real usage scenarios of users of different age groups can be simulated, and the test results are more in line with reality.

[0044] like Figures 1 to 7 As shown, the top of the extension plate 31 is rotatably connected to the first push plate 311, and a connecting plate 312 is rotatably connected between the two first push plates 311. The connecting plate 312 is slidably connected to the inside of the test box 3. The inside of the test box 3 is rotatably connected to two transmission rods 33. The upper half of the transmission rod 33 is provided with a thread. The transmission rod 33 is threadedly connected to the connecting plate 312 through the thread. A transmission gear 331 is fixed to the outside of the transmission rod 33. The second motor 36 is provided between the two transmission rods 33. The end of the rotating shaft of the second motor 36 is fixed with an output gear, and the output gear is meshed with the transmission gear 331.

[0045] When the second motor 36 drives the connecting plate 312 to descend to the top of the transmission gear 331, the connecting plate 312 drives the extension plate 31 to rotate to a state perpendicular to the test box 3 through the first push plate 311;

[0046] When the jack 312 is lifted up, the jack 312 is lifted up and the jack 313 is in the unlocking state, and the jack 314 is unlocked, so that the jack 312 can be unlocked.

[0047] like Figures 7 and 8 As shown, first sliders 313 are fixed on both sides of the bottom end of the first push plate 311, a connecting groove is provided at the top end of the extension plate 31, and an induction groove 314 is provided on both sides of the connecting groove, and a 5° angle is set between the vertical center line of the top end of the induction groove 314 and the vertical center line of the bottom end;

[0048] When the cam 312 is in the upright position, the first push plate 311 is in the upright position, and the force exerted downwardly by the connecting plate 312 to drive the first push plate 311 is in the vertical direction, and the extension plate 31 cannot be driven to rotate. To solve this problem, an induction slot 314 is provided at the top of the extension plate 31. When the connecting plate 312 drives the first push plate 311 to push the extension plate 31 downward, the first push plate 311 first drives the first slider 313 to slide from the top of the induction slot 314 to the bottom. Because the induction slot 314 is provided with an angle of 5°, the first slider 313 will slide obliquely. At this time, the first push plate 311 slides to the bottom end of the induction slot 314 and is induced to push the extension plate 31 obliquely. The first push plate 311 can push the extension plate 31 to rotate. At this time, the test can be carried out. After the test is completed, the connecting plate 312 pulls the first push plate 311 to reset, and the first push plate 311 pulls the first slider 313 to drive the extension plate 31 to rotate in the opposite direction and reset.

[0049] like Figures 1 to 9 As shown, both sides of the bottom of the test box 3 are provided with telescopic slots 34, the interior of the telescopic slots 34 is slidably connected to an extension block 321, and the end of the extension block 321 is fixed with a second push plate 32;

[0050] During use, the length of the test box 3 increases and the width also needs to be increased. At this time, the extension block 321 can be extended from the inside of the telescopic slot 34. After the extension block 321 is extended, it can extend the width of the test box 3 together with the second push plate 32, so that the width of the test box 3 is also increased during testing, which is closer to the real environment.

[0051] like Figures 1 to 7 As shown, the bottom end of the test box 3 is rotatably connected to a worm gear 35, and threaded rods 351 are fixed at both ends of the worm gear 35. The threaded rods 351 are threadedly connected to the extension block 321 on the same side. The bottom end of the transmission rod 33 is fixed to a worm 332, and both worms 332 are meshed with the worm gear 35.

[0052] When the second motor 36 drives the transmission rod 33 to rotate, the transmission rod 33 also drives the worm 332 to rotate. When the worm 332 rotates, it drives the worm wheel 35 to rotate. The rotation of the worm wheel 35 drives the threaded rod 351 to rotate. The rotation of the threaded rod 351 can drive the extension block 321 to extend from the inside of the telescopic slot 34. When the rotation of the extension plate 31 is completed, the threaded rod 351 drives it to extend synchronously from the inside of the telescopic slot 34. After the test is completed, the second motor 36 rotates in the opposite direction to simultaneously drive the extension block 321 and the extension plate 31 to reset.

[0053] like Figures 9 and 10 As shown, a receiving groove 322 is provided on one side of the extension block 321, and a top plate 37 is provided inside the receiving groove 322. The top plate 37 can slide inside the receiving groove 322;

[0054] When the extension block 321 extends from the telescopic slot 34 , the top plate 37 fills the gap between the extension block 321 and the telescopic slot 34 .

[0055] When the extension block 321 extends from the telescopic slot 34, a gap is created at the bottom of the test box 3, which affects the contact area between the test box 3 and the electric pedal 2. Therefore, when the extension block 321 extends, the top plate 37 extends from the inside of the receiving slot 322 and fills the gap between the extension block 321 and the telescopic slot 34. At this time, the top plate 37 can make up for the missing area at the bottom of the test box 3. When the extension block 321 is reset, the top plate 37 also returns to the inside of the receiving slot 322.

[0056] like Figures 9 and 10 As shown, a sliding frame 372 is fixed on both sides of the top of the top plate 37, and a first sliding groove 324 is opened on both sides above the first guide inclined surface 323. A sliding column is fixed on both sides of the sliding frame 372, and the sliding column is slidably connected to both sides of the first sliding groove 324;

[0057] The first slide 324 is provided with two sections of slideways. The first slideway 324 enables the sliding frame 372 to maintain horizontal movement, and the second slideway 324 enables the sliding frame 372 to move forward while moving downward.

[0058] When the extension block 321 extends from the telescopic slot 34, the top plate 37 remains in its original position. At this time, the first slide groove 324 can guide the sliding frame 372. When the sliding frame 372 slides to the second slide, the second slide drives the sliding frame 372 to move downward. At this time, the sliding frame 372 can drive the top plate 37 to move forward and downward at the same time. At this time, the top plate 37 can fill the gap between the extension block 321 and the telescopic slot 34. When the extension block 321 is reset, the second slide of the first slide groove 324 can drive the sliding frame 372 to rise. At this time, the top plate 37 is reset to the inside of the storage slot 322.

[0059] like Figures 9 and 10 As shown, a second slider 371 is fixed to one side of the top plate 37 away from the sliding frame 372 , a second slide groove 341 is opened on one side of the telescopic slot 34 , and the second slider 371 is slidably connected to the inside of the second slide groove 341 ;

[0060] When the second slider 371 slides to the bottom of the second chute 341 , the bottom of the top plate 37 is flush with the bottom of the test box 3 .

[0061] When the extension block 321 is extended, in order to ensure that the top plate 37 does not move, a second slider 371 is set to slide inside the second slide groove 341 to limit the top plate 37. The second slider 371 can slide up and down inside the second slide groove 341, and can support the other end of the top plate 37 when the sliding frame 372 slides in the first slide groove 324.

[0062] like Figures 9 and 10 As shown, a first guide slope 323 is provided on the side of the receiving groove 322 away from the second push plate 32, and a second guide slope 373 is provided on the side of the top plate 37 away from the second slider 371. The angles of the sliding frame 372 and the first guide slope 323 match the angle of the second section of the first slide groove 324.

[0063] During the lifting and lowering process of the top plate 37, interference will occur with the extension block 321. Therefore, a first guide slope 323 and a second guide slope 373 are provided. The angle of the sliding frame 372 and the first guide slope 323 matches the angle of the second section of the first slide groove 324. The first guide slope 323 and the second guide slope 373 can give way to the top plate 37 and the extension block 321, thereby preventing interference between the top plate 37 and the extension block 321.

[0064] like Figures 1 to 2As shown, a guide housing 122 is fixed to the top of the device housing 1, a screw rod 123 is rotatably connected to the inside of the guide housing 122, a moving block 121 is slidably connected to the inside of the guide housing 122, and the electric telescopic rod 12 is mounted on the bottom end of the moving block 121. A first motor 124 is mounted on one side of the device housing 1, and the end of the rotating shaft of the first motor 124 is fixedly connected to one end of the screw rod 123;

[0065] During the test process, it is necessary to test multiple positions of the top of the electric pedal 2 to further test the data of the electric pedal 2 in the actual usage scenario. When the position of the test box 3 needs to be switched, the electric telescopic rod 12 first drives the test box 3 to rise, and then starts the first motor 124 to drive the screw rod 123 to rotate. The screw rod 123 drives the moving block 121 to rotate and can slide inside the guide shell 122. At this time, the moving block 121 can drive the electric telescopic rod 12 to move, and the electric telescopic rod 12 drives the test box 3 to move through the pressure sensor 13. At this time, the movement of the position of the test box 3 can be completed.
