The intersection of the arc spherical surface 53 and the inclined constraint surface 54 is higher than the intersection of the spherical mounting portion 50 and the upper end of the assembly portion 49. A gap is reserved between the upper end of the assembly portion 49 and the inclined constraint surface 54. The inclined angle A formed between the inclined constraint surface 54 and the center line of the test vertical arm 37 is less than 20°. That is, through the constraint of the inclined constraint surface 54, the test block 40 can have a swing angle of less than 20° forward and a swing angle of less than 20° backward relative to the test vertical arm 37. Fig.12 As shown, the test press block 40 changes from a horizontal orientation to an inclined orientation.

[0081] In some implementations, such as Figure 2 , Fig.13As shown, support platforms 55 are extended from the middle of both ends of the first mobile platform 15 in the horizontal direction, and a support structure 56 is arranged on the support platform 55. The support structure 56 includes a support block 57, a connecting guide block 58, and a third oil cylinder 59. The connecting guide block 58 is horizontally arranged below the support platform 55.

The thickness d1 of the rubber pad 62 can be understood as the thickness after the test pressure is applied during the test. The rubber pad 62 is used to avoid direct hard contact between the test block 40 and the upper surface of the telescopic pedal, which affects the damage to the upper surface of the telescopic pedal; during the test block 40 applying pressure to the telescopic pedal, when the test block 40 swings back and forth to tilt, the lower surface of the test block 40 forms an inclination, and the lowest point of its lower surface does not exceed the lower surface of the rubber pad 62 when it is in the horizontal state, thereby protecting the telescopic pedal to be tested.

[0083] In some implementations, such as Figure 6 , Figure 7As shown, the installation template 24 is frequently inserted into the assembly groove 25, and due to the friction between the installation template 24 and the assembly groove 25, there is a probability that the outer wall of the installation template 24 and / or the inner wall of the assembly groove 25 will be worn. As a result, when a horizontal movable gap is generated between the outer wall of the installation template 24 and the inner wall of the assembly groove 25, it is necessary to compensate for this movable gap to ensure that the installation template 24 is stably placed in the assembly groove 25; based on this, two elastic supplementary structures 63 are arranged on the first movable platform 15, and the two elastic supplementary structures 63 are arranged at intervals at the rear end of the first movable platform 15 to generate a thrust on the installation template 24 from the outside of the first movable platform 15 to the inside; the elastic supplementary structure 63 includes a supplementary internal pressure block 64, a connecting screw 65, a stop nut 66, a spring 67, and a supplementary external connection block 68; the rear inner wall of the assembly groove 25 of the first movable platform 15 is provided with an accommodating notch 69, and the accommodating notch 69 is arranged from the first movable platform The middle part of 15 passes through the upper surface of the first movable platform 15 upward, so that the fitting condition between the supplementary internal pressure block 64 in the accommodating groove 69 and the outer wall of the mounting template 24 can be observed from above. The supplementary internal pressure block 64 is placed in the accommodating groove 69, the inner side surface of the supplementary internal pressure block 64 faces the inner side wall of the accommodating groove 69, and the outer side surface faces the direction of the assembly groove 25.

The supplementary inner pressure block 64 is a square block, and a connecting screw 65 is fixed to each of the four corners of the supplementary inner pressure block 64. Each connecting screw 65 is arranged with a spring 67 according to the above-mentioned connection method to enhance the stable support of the supplementary inner pressure block 64. A through hole that passes through the outer side of the first mobile platform 15 and the inner side of the accommodating slot 69 is opened on the inner wall of the first mobile platform 15 in the accommodating slot 69 for the connection screw 65 and the spring 67 to pass through. An accommodating groove 70 is opened on the inner wall of the supplementary outer connecting block 68 to place and constrain the outer end of the spring 67. In this way, when the stop nut 66 is loosened and the supplementary connecting block is pulled from the outside, the supplementary inner pressure block 64 can shrink toward the accommodating slot 69 until the inner side of the supplementary inner pressure block 64 is lower than the inner wall of the assembly slot 25, so as to avoid the supplementary inner pressure block 64 protruding from the assembly slot 25 and affecting the assembly of the mounting template 24. A pulling portion 72 is fixedly arranged on the connecting plate 71 to facilitate the simultaneous operation of the two elastic supplementary structures 63. A handle 83 is also fixed in the middle of the installation template 24 to facilitate moving.

[0084] In some implementations, such as Figure 3 As shown, an enclosure plate 73 higher than the upper surface of the cabinet 10 is fixedly provided on the upper surface of the cabinet 10, and a through slot is provided in the middle of the enclosure plate 73 which passes through the upper and lower surfaces of the enclosure plate 73, and a water collection area 74 is enclosed between the inner wall of the through slot and the upper surface of the cabinet 10, and the water collection area 74 is at least directly below the telescopic pedal to be tested; after orthographic projection from top to bottom, the area of ​​the telescopic pedal to be tested is smaller than the area of ​​the water collection area 74, and when water is sprayed from above, the sprayed water falls on the telescopic pedal, and then drips into the water collection area 74, and is collected by the water collection area 74.

For example, when it is necessary to spray more water onto the upper surface of the telescopic pedal to be tested, The opening degree of the water distribution control valve 79 can be increased. If less water needs to be sprayed above the telescopic pedal to be tested, the opening degree of the water distribution control valve 79 can be reduced to simulate the actual situation of the telescopic pedal under different rainfalls and increase the simulated test conditions. The three-way regulating valve 81 is arranged in the middle position of the water distribution pipe 77 and is connected to the water distribution pipe 77.

The bottom wall of the water collecting area 74 is provided with a convergence surface which gradually descends toward the return water outlet of the return water pipe 78, so that the dripping water gathers toward the return water outlet and finally flows back to the return water tank 76 through the return water pipe 78; wherein the return water tank 76 and the water storage tank 75 can be connected by a return pipe, and a filter 84 is installed on the return pipe to filter the water entering the water storage tank 75; the height of the water storage tank 75 is lower than that of the return water tank 76, and the water in the return water tank 76 flows to the water storage tank 75 under the action of gravity.

[0088] In some implementations, such as Figure 4 , Figure 5As shown, an elastic connection structure is used to connect the upper end of the test vertical arm 37 and the rocker arm 36, that is, the test vertical arm 37 has a certain amount of elastic activity in the vertical direction to reduce the excessive impact of the test pressure block 40 on the upper surface of the telescopic pedal to be tested during the descent of the test vertical arm 37. Specifically, the elastic connection structure is composed of four connecting bolts 88, an annular fixed connecting plate 89, and an intermediate spring 90.

The test swing arm can slide up and down in the mounting hole 91. The mounting hole 91 can be a through hole. A pressure sensor that cooperates with the upper end of the test vertical arm 37 is installed above the mounting hole 91 of the rocker arm 36 to detect the pressure of the test vertical arm 37 to obtain the pressure applied to the telescopic pedal.

When the set pressure is reached, the extension of the first oil cylinder 38 is stopped.

[0089] The automobile telescopic pedal simulation test method adopts the automobile telescopic pedal simulation test device having a test mechanism 12, and comprises the following steps:

[0090] S01. Outside the simulation test device, first assemble the connecting parts of the telescopic pedal to be tested on the lower surface of the second mounting portion 23 of the mounting template 24 by screws to simulate the actual use state of the telescopic pedal, and wait for the telescopic pedal to be tested and the mounting template 24 to be assembled as a whole on the simulation test device for installation test.

[0091] S02, the second moving mechanism 28 drives the test assembly 27 to move to the outside of the area occupied by the telescopic pedal to be tested above the cabinet 10, so as to make room for the installation test of the telescopic pedal to be tested, so as to avoid friction between the installation template 24 and the telescopic pedal to be tested and the test assembly 27 during installation. The first moving mechanism drives the first moving platform 15 to move to the outside near the top of the cabinet 10, so as to facilitate the assembly between the installation template 24 and the first moving platform 15 from the outside of the first moving platform 15; the first oil cylinder 38 retracts to the lowest position, so that the test vertical arm 37 rises to the highest position. It can be understood that after the test vertical arm 37 rises to the highest position, the height of the test pressing block 40 is above the upper surface of the telescopic pedal to be tested, so as to facilitate the subsequent smooth movement to the top of the telescopic pedal to be tested. During the contraction of the first oil cylinder 38, the second oil cylinder 39 extends to a corresponding length as the swing distance of the test vertical arm 37.

[0092] S03. Move the installation template 24 and the telescopic pedal to be tested as a whole, and move the installation template 24 horizontally to the top of the first movable platform 15, so that the first installation portion 22 of the installation template 24 is aligned with the assembly slot 25, and is inserted into the assembly slot 25 of the first movable platform 15 from the top of the cabinet 10, that is, the first installation portion 22 is inserted into the first installation slot 43, and the second installation portion 23 is inserted into the second installation slot 44. When the lower surface of the second installation portion 23 of the installation template 24 is in contact with the bottom of the second installation slot 44, the installation template 24 is assembled in place, and the entire installation template 24 is restricted in horizontal movement by the assembly slot 25; the power connector on the telescopic pedal to be tested is connected to the plug on the top of the cabinet 10 to realize the driving power supply of the telescopic pedal to be tested. Through operation, the telescopic pedal to be tested is extended outward and unfolded, and the upper surface of the telescopic pedal is arranged horizontally, showing a use state.

[0093] S04, obtain the product QR code on the telescopic pedal to be tested to obtain the relevant parameters of the telescopic pedal to be tested, and transmit the parameters of the telescopic pedal to be tested to the controller of the simulation test device. The controller matches the corresponding test mode from the simulation test mode library according to the obtained parameters of the telescopic pedal to be tested and performs the test action; when there is no matching test mode for the telescopic pedal to be tested in the simulation test mode library, the controller issues a prompt message and stops the execution of subsequent test actions of the test device. The staff is required to reset the corresponding test mode according to the product, and store the corresponding product parameters and the corresponding test mode in the controller; the method of obtaining the product QR code here can be to scan with a scanning device before the telescopic pedal to be tested, or to scan and obtain it after installation through the code reading device on the simulation test device. The obtained QR code information of the telescopic pedal to be tested includes the material, thickness, width and length of the pedal; according to the obtained QR code information of the telescopic pedal to be tested, the corresponding test mode is selected from the simulation test mode library to perform the test action.

[0094] S05, start the test process, that is, drive the installation component 11 to move through the first moving mechanism, so that the telescopic pedal to be tested moves to the test position, and the second moving mechanism 28 drives the test component 27 to move to the top of the telescopic pedal to be tested; move the test component 27 to the front stepping position (corresponding to the up and down position of the front row of the car) and the rear stepping position (corresponding to the up and down position of the rear row of the car) as the test area of ​​the telescopic pedal to perform a simulation test; test the front stepping position and the rear stepping position of the telescopic pedal in turn; if the front stepping position is pressure tested first, after the test is completed, move to the rear stepping position for pressure testing. For the test of the telescopic pedal, water can be sprayed on the telescopic pedal to perform a simulation test.

[0095] S06. During the simulation test of the area to be tested of the telescopic pedal, the first oil cylinder 38 extends to drive the rotation of the rocker arm 36, so that the test vertical arm 37 descends, and the lower surface of the test pressure block 40 is attached to the upper surface of the telescopic pedal. The test pressure of the test pressure block 40 on the telescopic pedal is determined by the extension length of the first oil cylinder 38, and the pressure is detected by the pressure sensor and fed back to the test device controller. When the feedback pressure reaches the set value, the first oil cylinder 38 stops extending and maintains the corresponding pressure. The test pressure block 40 is driven to move forward and backward through the extension and retraction of the second oil cylinder 39, which roughly simulates the angle change at the ankle when people get on and off the vehicle, so as to change the force position of the test pressure block 40 on the telescopic pedal, so as to perform a more realistic simulation test.

[0096] S07, repeating step S06, and performing repeated tests on the to-be-tested area of ​​the telescopic pedal for multiple times to obtain a more realistic test result of the telescopic pedal.

[0097] S08, obtaining the change of the telescopic pedal after the test to determine the quality of the telescopic pedal. Obtaining the change of the telescopic pedal after the test is not limited to obtaining image information of the upper surface of the telescopic pedal before the test and the image information of the upper surface of the telescopic pedal after the test, and comparing them to automatically determine the change of the upper surface of the telescopic pedal;

[0098] It also includes obtaining the changes in the connecting parts used in the telescopic pedal, such as through personnel observation, the connection condition of the telescopic pedal connecting parts, whether they are loose or damaged, so as to obtain the test results of the entire telescopic pedal; after removing the telescopic pedal after the test, manual observation is used to further observe the changes of the telescopic pedal after the test.

[0099] Before the test, the telescopic distances of the first oil cylinder 38 and the second oil cylinder 39 are set according to the material and thickness of the telescopic pedal. The telescopic force applied to the telescopic pedal is controlled by the telescopic movement of the first oil cylinder 38, and the test angle change of the test pressing block 40 on the telescopic pedal is controlled by the telescopic movement of the second oil cylinder 39. The driving distance of the first moving mechanism is set according to the width of the telescopic pedal, that is, the telescopic pedal is always driven to the central position of the test area by the first moving mechanism. The driving distance of the second moving mechanism 28 is set according to the length of the telescopic pedal, such as the moving distance of the test mechanism 12 toward one side of the test area and the distance to the front stepping position and the rear stepping position driven by the second moving mechanism 28;

[0100] Another method for simulating the test of a retractable pedal of a car is as follows: Fig.17 As shown, two testing mechanisms 12 are used, which are driven by a second moving mechanism 28, so that the two testing mechanisms 12 can form a separation or convergence movement. When they are separated, they move to the end of the testing device to wait for loading or unloading. When they form a convergence movement, they move to the front and rear stepping positions of the telescopic pedal to be tested. The main difference between this and the use of one testing mechanism 12 as mentioned above is that the use of two testing mechanisms 12 can simultaneously perform pressure tests on the front and rear stepping positions on the telescopic pedal, and correspondingly simulate the use of the front and rear passengers of the car stepping on the telescopic pedal at the same time for testing.
