Description

Technical Field

[0001] The present application relates to the technical field of operating panel detection, and in particular to an operating panel detection device and a detection method thereof. Background Art

[0002] The car operation panel is a part of the car. With the rapid development of the automobile industry, the car operation panel is also constantly improving and upgrading. Now the switches on the car operation panel are all operated by touch.

[0003] The automobile operation panel in the related art includes a housing on which a plurality of touch buttons are arranged. When a certain pressure is applied to the touch buttons, an operation is triggered.

[0004] To prevent accidental triggering of touch buttons on automotive control panels, these panels undergo factory testing to calibrate the touch pressure values ​​of the touchscreen switches to determine whether they trigger within a certain pressure range. Currently, touch buttons are tested manually, but manual testing can easily lead to large pressure errors, inaccuracies, and missed calibrations, resulting in significant deviations in the panel's touch button detection results. Summary of the Invention

[0005] In order to improve the accuracy of touch key detection of an operating panel, the present application provides a detection device and a detection method for an operating panel.

[0006] The present application provides an operating panel detection device and a detection method thereof, which adopt the following technical solutions:

[0007] A detection device for an operation panel, comprising a workbench, the workbench being used for placing a base for the operation panel, the workbench being provided with a detection structure for detecting the operation panel, the detection structure comprising an operation frame provided on the workbench and a test bench for being electrically connected to the operation panel, the operation frame being provided with a first counterweight and a second counterweight, the operation frame being provided with a first supporting surface for supporting the first counterweight and a second supporting surface for supporting the second counterweight, the second counterweight being located above the first counterweight, the first counterweight comprising a first fixing surface and a first force-applying surface, the second counterweight comprising a second fixing surface and a second force-applying surface, and the workbench being provided with a lifting structure for driving the operation frame to rise and fall;

[0008] When the detection structure is not detecting, the first fixing surface is in contact with the first supporting surface, the second fixing surface is in contact with the second supporting surface, and a gap is left between the second force-applying surface and the first counterweight;

[0009] When the lifting structure drives the operating frame to descend, the first force-applying surface first contacts the operating panel, and the first supporting surface is separated from the first fixed surface. Then, the second fixed surface contacts the first counterweight, and the second supporting surface is separated from the second fixed surface.

[0010] By adopting the above technical solution, the test bench is electrically connected to the operation panel, so that the test bench and the operation panel can communicate with each other through LIN. During testing, the lifting structure drives the operation frame, the first counterweight, and the second counterweight to descend. The first force-applying surface of the first counterweight first contacts the touch button on the operation panel. When the operation frame continues to descend, the first counterweight stops descending, causing a gap between the first support surface and the first fixed surface. Even if the weight of the first counterweight is applied to the touch button, when the touch button on the operation panel is triggered, the operation panel sends a test signal to the test bench. If the weight of the first counterweight cannot trigger the touch button, the lifting structure drives the operation frame to descend further, causing the second force-applying surface to contact the first counterweight. When the operation frame continues to descend, the second counterweight stops descending, causing a gap between the second support surface and the second fixed surface. Even if the weight of the second counterweight is applied to the touch button, when the touch button on the operation panel is triggered, the operation panel sends a test signal to the test bench, thereby identifying whether the trigger pressure of the touch button is outside the set tolerance range, thereby improving the accuracy of touch button detection of the operation panel.

[0011] Optionally, there are multiple second counterweights, and the multiple second counterweights are distributed in the vertical direction; in the process of the lifting structure driving the operating frame to descend, the multiple second fixed surfaces abut against the adjacent first counterweights or second counterweights in sequence from bottom to top, and separate the second supporting surface from the second fixed surface.

[0012] By adopting the above technical solution and setting a plurality of second counterweights, the detection range of the detection structure can be increased; when determining detection within a certain range, the setting of a plurality of second counterweights can increase the accuracy of the detection range of the detection structure.

[0013] Optionally, the lifting structure includes a third bracket arranged on the workbench, the third bracket is rotatably connected to a third screw rod, the third screw rod is vertically arranged, the third screw rod is equipped with a third slide which moves linearly along the axis of the third screw rod when the third screw rod rotates, and the third bracket is provided with a third driving member which drives the third screw rod to rotate.

[0014] By adopting the above technical solution, the third driving member drives the third screw to rotate, and the third screw drives the third slide to move along the axis direction of the third screw, so that the third slide block rises or falls, that is, the operating frame rises or falls.

[0015] Optionally, the workbench is provided with a driving base, a lifting structure and a horizontal X-axis displacement structure that moves along the horizontal X-axis direction. The horizontal X-axis displacement structure includes a first bracket arranged on the workbench, a first screw rod is rotatably connected to the first bracket, the first screw rod is equipped with a first slide that moves linearly along the axis of the first screw rod when the first screw rod rotates, and a first driving member that drives the first screw rod to rotate is provided on the first bracket.

[0016] By adopting the above technical solution, the first driving member drives the first screw to rotate, and the first screw drives the first slide to move along the axis direction of the first screw, that is, the base or the operating frame moves horizontally.

[0017] Optionally, the workbench is provided with a driving base, a lifting structure and a horizontal Y-axis displacement structure that moves along the horizontal Y-axis direction. The horizontal Y-axis displacement structure includes a second bracket arranged on the workbench, the second bracket is rotatably connected to a second screw rod, the second screw rod is equipped with a second slide that moves linearly along the axis of the second screw rod when the second screw rod rotates, and the second bracket is provided with a second driving member that drives the second screw rod to rotate; the axis of the first screw rod is perpendicular to the axis of the second screw rod.

[0018] By adopting the above technical solution, the second driving member drives the second screw to rotate, and the second screw drives the second slide to move along the axis direction of the second screw, that is, the base or the operating frame moves horizontally.

[0019] Optionally, a pressing structure for pressing the operation panel is provided on the base, and the pressing structure includes a pressing cylinder provided on a side surface of the base, and a piston rod of the pressing cylinder is connected to a pressing plate located above the operation panel.

[0020] By adopting the above technical solution, the piston rod of the pressing cylinder is retracted, causing the pressing plate to descend, and the operation panel is pressed by the pressing plate and the workbench.

[0021] Optionally, a plurality of pressing blocks are provided below the pressing plate.

[0022] By adopting the above technical solution, the pressure block can be used to apply force to multiple positions on the operation panel to fix the operation panel, making it difficult for the operation panel to move on the workbench.

[0023] Optionally, the pressing cylinder is a rotary cylinder.

[0024] By adopting the above technical solution and setting a rotating cylinder, the pressure plate can be raised and lowered and rotated. When the clamping structure is to clamp the operation panel, the pressure plate is no longer directly above the operation panel, making it convenient for the staff to place the operation panel on the workbench or remove the operation panel from the workbench.

[0025] A detection method for a detection device of an operation panel comprises the following steps:

[0026] Step 1: Place the operation panel on the workbench and establish LIN communication between the operation panel and the test bench through the connector;

[0027] In step 2, the operating frame is driven downward by the lifting structure, so that the first force-applying surface contacts the touch button and the first fixed surface is separated from the first supporting surface. The test bench reads the pressure data detected by the touch button on the operating panel through LIN, determines whether the pressure data of the touch button is within the set tolerance range, and identifies whether the conductive force of the touch button structure meets the requirements;

[0028] If the detected pressure data is not within the set tolerance range, proceed to step 3; if the detected pressure data is within the set tolerance range, proceed to step 5;

[0029] Step 3: The operating frame is driven down by the lifting structure, so that the second counterweight is superimposed on the first counterweight and the second fixed surface is separated from the second supporting surface, thereby increasing the pressure on the touch button. The test bench reads the pressure data detected by the touch button on the operation panel through LIN, determines whether the pressure data of the touch button is within the set tolerance range, and identifies whether the conductive force of the touch button structure meets the requirements;

[0030] If the detected pressure data is not within the set tolerance range, proceed to step 4; if the detected pressure data is within the set tolerance range, proceed to step 5;

[0031] Step 4: The operating frame is driven down by the lifting structure, and a new second counterweight is superimposed on the second counterweight to increase the pressure on the touch button. The test bench reads the pressure data detected by the touch button on the operation panel through LIN, determines whether the pressure data of the touch button is within the set tolerance range, and identifies whether the conductive force of the touch button structure meets the requirements;

[0032] If the detected pressure data is not within the set tolerance range, repeat step 4; if the detected pressure data is within the set tolerance range, proceed to step 5;

[0033] Step 5: After passing the test, send a command to the product to write the calibrated pressure data into the touch button threshold. The test bench controller will upload the calibrated data of each product to the server; the lifting structure, detection structure, and pressing structure are reset.

[0034] By adopting the above technical solution, the operating frame is driven down by the lifting structure, so that the first counterweight acts on the touch button to identify whether the touch button is triggered. If the touch button cannot be triggered, the second counterweight is superimposed on the first counterweight until the touch button is triggered, thereby identifying whether the pressure data of the touch button is within the set tolerance range and determining whether the operating panel is qualified.

[0035] Optionally, the operation panel in step 1 is fixed on the workbench by a clamping structure.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. The test bench controller is electrically connected to the operation panel so that the test bench controller and the operation panel can communicate with each other through LIN. During the test, the lifting structure drives the operation frame, the first counterweight and the second counterweight to descend. The first force-applying surface of the first counterweight first contacts the touch button on the operation panel. When the operation frame continues to descend, the first counterweight stops descending, so that a gap is generated between the first support surface and the first fixed surface. Even if the gravity of the first counterweight is applied to the touch button, when the touch button on the operation panel is triggered, the operation panel sends a signal test to the test bench controller. If the gravity of the first counterweight cannot trigger the touch button, the lifting structure drives the operation frame to descend further, and the second force-applying surface contacts the first counterweight. When the operation frame continues to descend, the second counterweight stops descending, so that a gap is generated between the second support surface and the second fixed surface. Even if the gravity of the second counterweight is applied to the touch button, when the touch button on the operation panel is triggered, the operation panel sends a signal test to the test bench, thereby identifying whether the trigger pressure of the touch button is within the set tolerance range, thereby improving the accuracy of the touch button detection of the operation panel.

[0061] Reference Figure 1 The lifting structure 4 is provided on the second slide 63 and is used to drive the detection structure 3 to move up and down. The lifting structure 4 includes a third bracket 41, a third screw rod 42, a third slide 43, a third guide rail 44, and a third driving member 45.

[0062] Reference Figure 1, the third bracket 41 is vertically arranged on the second slide 63. The third screw rod 42 is fixed to the third bracket 41 through two bearing seats, and the third guide rail 44 is fixed to the third bracket 41. The third screw rod 42 and the third guide rail 44 are parallel to each other and are both vertically arranged. A third threaded hole 431 and a third through-hole 432 are provided on the third slide 43. The third screw rod 42 is threadedly connected to the third threaded hole 431, and the third guide rail 44 is passed through the third through-hole 432. The axis of the third screw rod 42 is perpendicular to the axis of the first screw rod 52, that is, the movement direction of the first slide 53 and the movement direction of the third slide 43 are perpendicular to each other.

[0063] Reference Figure 1 The third driving member 45 includes a third motor 451, which is fixedly connected to an end of the third bracket 41 away from the third screw rod 42.

[0064] Reference Figure 1 When the third motor 451 is working, it drives the third screw rod 42 to rotate, and the third screw rod 42 drives the third slide 43 to move in the vertical direction, that is, the detection structure 3 is raised or lowered.

[0065] Reference Figure 1 and Figure 2 The detection structure 3 includes an operating frame 31 , a first counterweight 32 , a second counterweight 33 and a test platform 34 .

[0066] The operating frame 31 includes a vertical plate 311, a first horizontal plate 312 and a second horizontal plate 313. One side of the vertical plate 311 is fixedly connected to the third slide 43. The first horizontal plate 312 is fixedly connected to the end surface of the vertical plate 311 away from the third slide 43. The upper end surface of the first horizontal plate 312 is set as the first support surface.

[0067] Reference Figure 1 and Figure 2 The upper end surface of the first horizontal plate 312 defines a first through hole 3121. The first counterweight 32 includes a first counterweight block 321 and a first pressure rod 322. The first pressure rod 322 extends through the first through hole 3121, and the first counterweight block 321 is fixedly connected to the upper end surface of the first pressure rod 322. The end surface of the first pressure rod 322 facing away from the first counterweight block 321 serves as a first force-applying surface, while the end surface of the first counterweight block 321 facing the first pressure rod 322 serves as a first fixing surface.

[0068] Reference Figure 1 and Figure 2When the detection structure 3 does not detect the touch button on the operation panel, the detection structure 3 is in the initial state, the first counterweight 32 does not contact the operation panel, the first fixed surface on the first counterweight block 321 conflicts with the first supporting surface on the first horizontal plate 312, and the gravity of the first counterweight 32 acts on the first horizontal plate 312.

[0069] Reference Figure 1 and Figure 2 The lifting structure 4 drives the operating frame 31 to descend, so that when the first counterweight block 321 detects the operating panel, the first force-applying surface of the first pressure rod 322 first contacts the touch button on the operating panel. As the lifting structure 4 continues to drive the vertical plate 311 and the first horizontal plate 312 to descend together, a gap is generated between the first supporting surface and the first fixed surface, so that the gravity of the first counterweight 32 is applied to the touch button.

[0070] In this embodiment, two second horizontal plates 313 are provided. Both second horizontal plates 313 are fixedly connected to the end surface of the vertical plate 311 facing the first horizontal plate 312. Both second horizontal plates 313 are located above the first horizontal plate 312 and are distributed in the vertical direction. The upper end surface of the second horizontal plate 313 is configured as a second support surface.

The second counterweight member 33 includes a second counterweight block 331 and a second pressure rod 332, and the second pressure rod 332 is disposed within the second through hole 3131. The second counterweight block 331 is fixedly connected to the upper end surface of the second pressure rod 332. The end surface of the second pressure rod 332 facing away from the second counterweight block 331 is configured as a second force-applying surface, and the end surface of the second counterweight block 331 facing the second pressure rod 332 is configured as a second fixed surface.

[0072] Reference Figure 1 and Figure 2 When the detection structure 3 is not detecting a touch button on the operation panel, the second fixed surface of the second counterweight 331 contacts the second supporting surface of the second horizontal plate 313. The gravity of the second counterweight 33 acts on the second horizontal plate 313, leaving a gap between the second pressure rod 332 and the first counterweight 321. At the same time, a gap remains between two adjacent second counterweights 33.

[0073] Reference Figure 2 and Figure 3When the pressure of the first counterweight 32 on the touch button is less than the pressure data set by the test bench 34, the lifting structure 4 continues to drive the operating frame 31 to descend, so that the lowermost second force-applying surface contacts the upper end surface of the first counterweight block 321, and a gap is created between the lowermost second fixed surface and the second supporting surface, so that the gravity of the lowermost second counterweight 33 is applied to the first counterweight block 321, that is, the gravity of the second counterweight 33 and the first counterweight 32 are applied to the touch button together.

[0074] Reference Figure 2 and Figure 3 If the combined gravity of the first counterweight 32 and the second counterweight 33 is less than the pressure data set by the test bench 34, the lifting structure 4 continues to drive the operating frame 31 to descend, even if the top second horizontal plate 313 descends, so that the second force-applying surface of the upper second counterweight 33 contacts the lower second counterweight block 331, and a gap is generated between the top second horizontal plate 313 and the top second counterweight block 331, so that the gravity of the upper second counterweight 33 is applied to the lower second counterweight block 331, even if the gravity of the two second counterweights 33 and the first counterweight 32 is applied to the touch button together.

[0075] In other embodiments, one, three, or other numbers of the second horizontal plate 313 and the second counterweight 33 are provided.

[0076] Reference Figure 1 The test bench 34 is fixedly connected to the workbench 1. A connector is electrically connected to the controller on the test bench 34. The end of the connector, remote from the controller, is electrically connected to the operation panel, enabling LIN communication between the operation panel and the test bench 34 for exchanging calibration data. When a touch button on the operation panel is triggered, the operation panel transmits a test signal to the test bench 34.

[0077] The position of the detection structure 3 is adjusted by the horizontal X-axis displacement structure 5 and the horizontal Y-axis displacement structure 6 so that the detection structure 3 can detect each touch button on the operation panel. The test bench 34 reads the pressure data detected by the product through LIN, and determines whether the pressure data of each touch button position is within the set tolerance range, and identifies whether the conductive force of each touch button structure of the operation panel meets the requirements.

[0078] A detection method for an operation panel detection device comprises the following steps:

[0079] Step 1: Place the operation panel on the workbench 1 and establish LIN communication between the operation panel and the test bench 34 through the connector; fix the operation panel to the base 11 through the clamping structure 2, and adjust the horizontal position of the detection structure 3 through the horizontal X-axis displacement structure 5 and the horizontal Y-axis displacement structure 6 to move the detection structure 3 to the top of the touch button to be tested on the operation panel;

[0080] Step 2: The operating frame 31 is driven downward by the lifting structure 4, so that the first force-applying surface contacts the touch button and the first fixed surface is separated from the first supporting surface. The test bench 34 reads the pressure data detected by the touch button on the operating panel through the LIN, determines whether the pressure data of the touch button is within the set tolerance range, and identifies whether the conductive force of the touch button structure meets the requirements;

[0081] If the detected pressure data is not within the set tolerance range, proceed to step 3; if the detected pressure data is within the set tolerance range, proceed to step 5;

[0082] Step 3: The lifting structure 4 drives the operating frame 31 downward, causing the second counterweight 33 to overlap the first counterweight 32 and separating the second fixed surface from the second supporting surface, thereby increasing the pressure on the touch button. The test bench 34 reads the pressure data detected by the touch button on the operation panel via LIN, determines whether the pressure data of the touch button is within the set tolerance range, and identifies whether the conductive force of the touch button structure meets the requirements.

[0083] If the detected pressure data is not within the set tolerance range, proceed to step 4; if the detected pressure data is within the set tolerance range, proceed to step 5;

[0084] Step 4: The operating frame 31 is driven downward by the lifting structure 4, and a new second counterweight 33 is superimposed on the second counterweight 33 to increase the pressure on the touch button. The test bench 34 reads the pressure data detected by the touch button on the operation panel through LIN, determines whether the pressure data of the touch button is within the set tolerance range, and identifies whether the conductive force of the touch button structure meets the requirements;

[0085] If the detected pressure data is not within the set tolerance range, repeat step 4; if the detected pressure data is within the set tolerance range, proceed to step 5;

[0086] Step 5: After passing the test, send a command to the product to write the calibrated pressure data into the touch button threshold. The test bench 34 will upload the calibrated data of each product to the server; the lifting structure 4, the detection structure 3, and the pressing structure 2 are reset.

[0087] The implementation principle of Example 1 is:

[0088] Example 2
