Description

Technical Field

[0001] This invention relates to the technical field of vehicle switch testing, and more particularly to a multi-directional lever force testing device and method for vehicle switches. Background Technology

[0002] There are many types of automotive switches, such as rotary switches, momentary switches, and toggle switches. Currently, automotive central control modules typically use toggle switches to adjust the vehicle's temperature, volume, and airflow. Since the human eye cannot interact with the switches while driving, adjusting toggle switches is largely done blindly. In this process, after the switch is moved, the user needs to judge its status through touch, such as the interaction of displacement and force feedback. To ensure clear tactile feedback and noticeable displacement when using toggle switches, the air conditioning controller in the automotive central control module requires force feedback testing of the toggle switches during manufacturing.

[0003] Currently, factory testing typically uses ordinary testing instruments that cannot determine the force applied, or even relies solely on manual manipulation. Because different people have different perceptions, it's impossible to measure the force applied, identify defects, intercept faulty components, or provide accurate measurements. Ordinary testing instruments, such as mechanical and electronic tools used for toggle switch testing, cannot accurately capture numerical values ​​or output ergonomic specifications, such as the toggle switch's actuation force, its anti-vibration and self-locking force, force resolution accuracy, linearity, and displacement range. Whether these force values ​​indicate compliance or not, and whether the product responded successfully, also requires manual judgment. Furthermore, during factory production, different car brands' air conditioning controllers have different characteristics, resulting in inconsistent toggle switch actuation directions and positions. Current testing instruments struggle to achieve automated and intelligent toggle switch testing. Summary of the Invention

[0004] This invention addresses the technical problem that vehicle-mounted toggle switch lever force testing requires manual intervention, making it difficult to effectively measure force, identify defective products, and resulting in low testing accuracy. It provides a multi-directional lever force testing device and method for vehicle-mounted switches.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0006] A vehicle-mounted switch multi-directional lever force testing device includes a carrier, a control module, and multiple motion modules that move linearly along one axis. The carrier is equipped with a clamping module for placing the test product. Each motion module includes a first horizontal axis module, a second horizontal axis module, a vertical axis module, and a rotation axis module. The motion axes of the first and second horizontal axis modules are positioned on a first horizontal plane and are perpendicular to each other. The axis of the vertical axis module is perpendicular to the first horizontal plane. The rotation axis module rotates along the axis of the vertical axis module. The carrier is slidably mounted on the second horizontal axis module. The vertical axis module is slidably mounted on the first horizontal axis module and installed directly above the second horizontal axis module. The vertical axis module has a movable end near the carrier, and the rotating axis module is mounted on the movable end of the vertical axis module. The rotating axis module is provided with a lever assembly for moving the test product. The control module is connected to each of the action modules and is put into a working position through the second horizontal axis module. The relative position between the lever assembly and the test product on the carrier is adjusted through the first horizontal axis module, the vertical axis module, and the rotating axis module. The action module drives the lever assembly to perform lever testing on the test product.

[0007] Furthermore, the lever assembly includes lever fingers for simulating a human hand and a pressure sensor. Two lever fingers are provided and connected to the pressure sensor, which is signal-connected to the control module.

[0008] Furthermore, the second horizontal axis module includes a sliding module and a support plate; the support plate is slidably disposed on the sliding module for assembling the carrier and positioning the carrier on the second horizontal axis module.

[0009] Furthermore, the first horizontal axis module includes a sliding module and a first adapter plate; the adapter plate is slidably mounted on the sliding module, and the first adapter plate is used to dock with the vertical axis module, driving the vertical axis module to slide on the sliding module of the first horizontal axis module.

[0010] Furthermore, the vertical axis module includes a sliding module and a second adapter plate. The second adapter plate is disposed at the movable end of the vertical axis module and is slidably connected to the sliding module to complete the connection between the vertical axis module and the rotating axis module.

[0011] Furthermore, the first horizontal axis module and the second horizontal axis module also include cable chains, which are used to protect and restrain the wire harnesses and air pipes that carry the first horizontal axis module and the second horizontal axis module.

[0012] Furthermore, the sliding module includes a drive motor, a synchronization component, and a slide rail assembly; the slide rail assembly provides a sliding platform, and the drive motor and synchronization component are driven and connected to control the synchronization component to perform sliding operations on the slide rail assembly; the slide rail assembly is also provided with an origin switch and a limit switch for controlling and limiting the sliding distance.

[0013] Furthermore, the rotating shaft module includes a rotary mechanism cylinder and a rotary mechanism connector. The rotary mechanism cylinder is installed at the movable end of the vertical shaft module, and the two ends of the rotary mechanism connector are respectively connected to the rotary mechanism cylinder and the actuating assembly.

[0014] Furthermore, it also includes a safety protection component, which includes a chassis, a two-hand start button, a safety sensor, a touch screen, an indicator device, and a pressure sensor controller. The chassis contains a workspace for installing the carrier, control module, and motion module. The two-hand start button, safety sensor, touch screen, indicator device, and touch screen are mounted on the chassis. The two-hand start button is used to start the equipment when pressed by the operator. The safety sensor is used to detect whether a hand has accidentally entered the workspace inside the chassis. The touch screen is used to display the equipment's operating status and to facilitate human-machine interaction during testing. The indicator device is used to indicate the equipment's operating status. The pressure sensor controller is used to calibrate the pressure sensor, perform upper and lower limit management, accuracy classification, and force value display.

[0015] This invention also provides a method for testing the force of a multi-directional lever of a vehicle switch, applied to the aforementioned multi-directional lever force testing equipment for vehicle switches, the method comprising:

[0016] S1. In the standby state, the test program of the test product is called, which includes the control program for the movement module to run at the corresponding position and the test angle adjustment.

[0017] S2. The test product is loaded into the carrier. After the operator starts the test, the test product moves to the working position under the drive of the second horizontal axis module.

[0018] S3. Under the control of the control module, the first horizontal axis module, the vertical axis module, and the rotating axis module drive the lever assembly to move above the test product according to the test procedure.

[0019] S4. Based on the angle of the test product, the lever assembly is driven by the first horizontal axis module and the second horizontal axis module to perform a swing lever operation. The force value parameter is generated and recorded by the pressure sensor to obtain the test data.

[0020] This invention performs force testing on vehicle-mounted lever switches using a carrier, control module, and multi-axial motion module. The equipment automates lever operation without requiring manual intervention to determine the relationship between lever response and product parameters. It automatically tests synchronized lever response parameters, identifies and intercepts defective products, and improves the automation level of lever switch force testing. It provides visualized programmable force test results. The equipment offers improved monitoring accuracy and high resolution of lever force values, ensuring smooth and reliable force application during toggle movements. It is compatible with multiple products and allows for pre-setting of angles based on different assembly angles. Attached Figure Description

[0041] Example 1

[0042] Figure 1 This diagram shows an overall perspective view of the multi-directional lever force testing equipment for vehicle-mounted switches in this embodiment. Figure 2 The diagram shows the structure of the main components of the vehicle-mounted switch multi-directional lever force testing equipment in this embodiment.

[0043] like Figure 1-2This embodiment provides a multi-directional lever force testing device for vehicle-mounted switches. The testing device includes a carrier 10, a control module, and multiple motion modules 20 that move linearly along one axis. The carrier 10 is mainly used to load and position the test product 50, and a connecting seat is provided on the carrier 10 to allow the test product 50 to be powered on. The control module is mainly used to control the motion modules 20 to perform force testing operations according to the input test program. The motion modules 20 are mainly used to move the test product 50 into the working position and align the lever assembly 30 with the test product 50 to perform the corresponding lever operation.

[0044] In terms of specific structure, the carrier 10 is provided with a clamping module 11 for placing the test product 50. This clamping module 11 is used to clamp the test product 50 placed on the carrier 10. Preferably, see [reference needed]. Figure 7 In this embodiment, the clamping module 11 includes a rotary clamping cylinder. When the rotary clamping cylinder picks up and feeds the material, it is in the loose state. After the test product 50 is placed, the control module controls the rotary clamping cylinder to clamp and fix the test product 50 on the carrier 10, ensuring that the test product 50 will not fall off during subsequent processing.

[0045] For details regarding Action Module 20, please refer to [link / reference]. Figure 2 The motion module 20 specifically includes a first horizontal axis module 21, a second horizontal axis module 22, a vertical axis module 23, and a rotation axis module 24. The four motion modules 20 cooperate with each other to control the movement of the carrier 10 at the material picking station and the working station, the alignment between the lever assembly 30 and the test product 50, and the lever action of the lever assembly 30.

[0046] For specific axial aspects, please refer to Figure 3 , Figure 3 The diagram shows the axial arrangement of the motion module 20 in this embodiment, where the X-axis represents the axial direction of the first horizontal axis module 21, the Y-axis represents the axial direction of the second horizontal axis module 22, the Z-axis represents the axial direction of the vertical axis module 23, and the R-axis represents the axial direction of the rotation axis module 24.

[0047] Specifically, the actuating axes of the first horizontal axis module 21 and the second horizontal axis module 22 are set on the first horizontal plane and are perpendicular to each other. That is, the planar position of the lever assembly 30 in the horizontal plane direction can be controlled by the first horizontal axis module 21 and the second horizontal axis module 22. The axis of the vertical axis module 23 is perpendicular to the first horizontal plane, and the rotation axis module 24 rotates along the axis of the vertical axis module 23.

[0048] In terms of specific arrangement, the carrier 10 is slidably mounted on the second horizontal axis module 22, the first horizontal axis module 21 is mounted directly above the second horizontal axis module 22, and the vertical axis module 23 is slidably mounted on the first horizontal axis module 21. The side of the vertical axis module 23 closest to the carrier 10 is the movable end, and the rotating axis module 24 is mounted on the movable end of the vertical axis module 23. The rotating axis module 24 is provided with a lever assembly 30 for moving the test product 50. The control module is connected to each action module 20 and is positioned in the working position via the second horizontal axis module 22. The relative position between the lever assembly 30 and the test product 50 on the carrier 10 is adjusted by the first horizontal axis module 21, the vertical axis module 23, and the rotating axis module 24. The action module 20 drives the lever assembly 30 to perform lever testing on the test product 50.

[0049] Please refer to the details. Figure 8 The control module adjusts the corresponding angle between the lever assembly 30 and the test product 50 via the rotating shaft module 24. This adjustment works by inputting the test program for the corresponding test product 50 before processing and editing its position coordinates. Since different test products 50 have different toggle angles, the angle of the lever assembly 30 is adjusted accordingly. For example, the rotating shaft module 24 is pre-adjusted to the corresponding position based on the lever angle of the test product 50. The rotating shaft module 24 adjusts the rotation angle using the displacement of the hydraulic buffer. The accuracy of the angle is observed based on the cylinder scale, and the angle position is determined by a magnetic ring sensor. When the position is correct, a signal is output to the test equipment PLC (Programmable Logic Controller). For instance, when the angle of the test product 50 needs to be set to 0 degrees, the rotary cylinder does not rotate; when set to 30 degrees, the cylinder rotates 30 degrees, and so on for other angles such as 45 degrees.

[0050] In addition, the control module adjusts the relative position between the lever assembly 30 and the test product 50 through the first horizontal axis module 21, the second horizontal axis module 22, and the vertical axis module 23. For example, the second horizontal axis module 22 drives the test product 50 into the working position, which is set directly below the lever assembly 30. The first horizontal axis module 21 and the vertical axis module 23 adjust the position of the lever assembly 30 in the X-axis direction and the Z-axis direction, respectively, so that the lever assembly 30 falls into the lever position of the test product 50.

[0051] Meanwhile, in this embodiment, the control module also drives the lever assembly 30 to move through the actions of the first horizontal axis module 21 and the second horizontal axis module 22, thereby realizing the lever action of the lever assembly 30. After the lever assembly 30 is in place, the control module controls the first horizontal axis module 21 and the second horizontal axis module 22 to move along the X and Y axes according to the angle of the lever switch, based on the angle of the test product 50, causing the lever finger 31 to swing and move the lever switch lever. For example, at 0 degrees, the Y axis reciprocates along the Y+ and Y- directions within the lever travel; at 90 degrees, the X axis reciprocates along the X+ and X- directions within the lever travel; at 45 degrees, the X and Y axes reciprocate according to the calculated function coordinates after composite calculation within the lever travel.

[0052] The advantage of this embodiment is that it uses a carrier 10, a control module, and a multi-axial motion module 20 to perform force testing on the vehicle-mounted lever switch. This equipment can automate the product lever operation without manual intervention to judge the relationship between the product lever response and product parameters, automatically test the lever response synchronization parameters, identify and intercept defective products, improve the automation level of lever switch force testing, and provide visualized program force test results. The equipment improves the monitoring accuracy of the lever force value, has high resolution, and the force application of the lever action is smooth and reliable. It is compatible with multiple products and can preset the angle according to different assembly angles.

The lever fingers 31 are configured to simulate two fingers of a human hand. The lever fingers 31 are connected to the pressure sensor 32, which is connected to the control module for signal transmission. Preferably, the pressure sensor 32 is a resistance strain gauge sensor with a theoretical conversion accuracy of 0.2 grams, far exceeding the target accuracy resolution of 10 grams. The pressure sensor 32 can measure and record the lever force of the lever fingers 31.

[0056] As a preferred option, please refer to Figure 2 and Figure 4 The second horizontal axis module 22 includes a sliding module 25, a cable chain 26, and a support plate 221. The support plate 221 is slidably mounted on the sliding module 25 for assembling the carrier 10 and positioning the carrier 10 on the second horizontal axis module 22. The cable chain 26 is used to load the motor drive harness and the internal test harness of the product, and its function is to protect the harness and constrain interference during movement.

[0057] Also preferred, please refer to Figure 5 The first horizontal axis module 21 includes a sliding module 25, a first adapter plate 211, and a cable chain 26 that functions identically to the second horizontal axis module 22. The adapter plate is slidably mounted on the sliding module 25 and is used to dock with the vertical axis module 23, thereby driving the vertical axis module 23 to slide on the sliding module 25 of the first horizontal axis module 21. Please refer to [link / reference]. Figure 6 The vertical axis module 23 includes a sliding module 25 and a second adapter plate 231. The second adapter plate 231 is disposed at the movable end of the vertical axis module 23 and is slidably connected to the sliding module 25 to complete the connection between the vertical axis module 23 and the rotating axis module 24.

[0058] Furthermore, in the above preferred embodiment, the first horizontal axis module 21, the second horizontal axis module 22, and the vertical axis module 23 are linear sliding modules 25. In this embodiment, the sliding module 25 includes a drive motor, a synchronization component, and a slide rail assembly. The slide rail assembly provides a sliding platform, and the drive motor and the synchronization component are driven and connected to control the synchronization component to perform sliding operations on the slide rail assembly. The slide rail assembly is also provided with an origin switch and a limit switch for controlling and limiting the sliding distance.

[0059] Please see Figure 2 and Figure 6 The rotating shaft module 24 includes a rotating mechanism cylinder 241 and a rotating mechanism connector 242. The rotating mechanism cylinder 241 is installed at the movable end of the vertical shaft module 23, and the two ends of the rotating mechanism connector 242 are respectively connected to the rotating mechanism cylinder 241 and the lever assembly 30.

[0060] In some embodiments, please refer to Figure 9 The vehicle-mounted switch multi-directional lever force testing equipment also includes a safety protection component 40, which comprises a chassis 41, a two-hand start button 42, a safety sensor 43, a touch screen 44, an indicator device 45, and a pressure sensor controller 46. The chassis 41 houses the working space for the mounting carrier 10, the control module, and the action module 20. The two-hand start button 42, safety sensor 43, touch screen 44, and indicator device 45 are mounted on the chassis 41. Functionally, the two-hand start button 42 is used to start the equipment when pressed by the operator; the safety sensor 43 detects whether a hand has accidentally entered the working space inside the chassis 41; the touch screen 44 displays the equipment's operating status and facilitates human-machine interaction during testing; the indicator device 45 indicates the operating status of the equipment; and the pressure sensor controller 46 calibrates the pressure sensor 32, managing upper and lower limits, accuracy settings, and force value display.

[0061] The indicating device 45 includes an alarm red light, a warning yellow light, and a running green light. When the equipment malfunctions or alarms, a red light indicates a failed test; a yellow light indicates manual or maintenance mode; and a green light indicates the equipment is ready and functioning normally. Preferably, the safety protection component 40 also includes an emergency stop button 47, which can be pressed by the operator in emergency situations to cut off power to the moving parts.

[0062] Example 3

[0063] Please see Figure 10 This embodiment provides a method for testing the force of a multi-directional lever of a vehicle switch. This testing method is applied to the multi-directional lever force testing equipment for vehicle switches in Embodiment 1 or Embodiment 2. The method specifically includes:

[0064] S1. In the standby state, the test program of the test product is called, which includes the control program for the movement module to run at the corresponding position and the test angle adjustment.

[0065] S2. The test product is loaded into the carrier. After the operator starts the test, the test product moves to the working position under the drive of the second horizontal axis module.

[0066] S3. Under the control of the control module, the first horizontal axis module, the vertical axis module, and the rotating axis module drive the lever assembly to move above the test product according to the test procedure.

[0067] S4. Based on the angle of the test product, the lever assembly is driven by the first horizontal axis module and the second horizontal axis module to perform a swing lever operation. The force value parameter is generated and recorded by the pressure sensor to obtain the test data.

[0068] Of course, for a better user experience, please refer to [link / reference]. Figure 11 The following provides a specific operation process for this embodiment.

[0069] 1. At the start of the test, power on the equipment. Perform a safety self-test: The equipment checks the entire system, including power supply, electrical signals, air supply, program, and protective sensors. If the check is normal, it enters the working standby state; if an abnormality occurs, it enters the alarm state. After the check is normal, program configuration is performed. Specifically, the operator scans the product's QR code with a barcode scanner while the product is in working standby state, calling up the corresponding product program. The test program is used to drive the XYZ axis motion module to the specific operating position.

[0070] 2. Position pre-adjustment: Based on the angle of the test product, the R-axis motion module adjusts the lever assembly to the corresponding position in advance according to the lever angle of the test product.

[0071] 3. Product Placement: Place the product with the lever into the loading fixture and start the equipment using the two-hand buttons. Manually scan the product's QR code. The equipment compares the QR code with the database in the interlock system. Products that haven't passed through the checkpoint are allowed to pass; those that have are intercepted. If the feedback is correct, press the double-start button. The rotating clamping cylinder clamps the product, and the communication module docking mechanism lifts and communicates with the product. The product display screen lights up, showing the preset values. The Y-axis motion module moves the fixture from its original position to the working position along the Y+ direction, and the equipment begins operation.

[0072] IV. The motion module controls the lever operation.

[0073] R-axis motion module rotation drive: The rotary cylinder rotates according to a preset angle. When the lever is at 0 degrees, the rotary cylinder does not rotate. When the lever is at 45 degrees, the rotary cylinder rotates 45 degrees.

[0074] The XYZ axis motion module moves the lever assembly to the test position: The X-axis motion module moves the test product in the X+ direction to a position perpendicular to the Y-axis motion module, then the Z-axis motion module moves downwards in the Z- direction, and the lever finger moves to the lever switch position. For details on the lever finger and lever switch angle layout, please refer to [reference needed]. Figure 8 .

[0075] XY-axis motion module coordinated lever operation: When the position is correct, the X-axis and Y-axis motion modules move according to the angle of the lever switch on the test product, causing the lever finger to swing and move the lever switch. For example, at 0 degrees, the Y-axis motion module reciprocates along the Y+ and Y- directions within the lever's travel. For example, at 90 degrees, the X-axis motion module reciprocates along the X+ and X- directions within the lever's travel. For example, at 45 degrees, the X-axis and Y-axis motion modules reciprocate according to the calculated function coordinates after composite calculation within the lever's travel.

[0076] V. Force Value Parameter Recording and Generation: When the lever is moved by the finger, the force is transmitted to the pressure sensor. The pressure sensor feeds back the force value data and displays it on the touchscreen. The force value movement curve is visualized based on the sampling frequency. Simultaneously, the product display screen also shows the number of toggle movements and whether the switch parameter response is synchronized, and whether the lever force is within the specified range. If it is not up to standard, an alarm is triggered to block the operation. Regardless of whether it passes or fails, the switch response parameters and lever force data are saved for later analysis and traceability.

[0077] Preferably, the force value test judgment content is as follows (specific force values ​​are represented by letters): Let the lever travel be A (mm), divide A into 1000 equal parts, and move the X-axis and Y-axis motion modules in steps according to A‰ distance. Record the force value at the corresponding movement position 1000 times to form a curve. Extract the peak force value in the 1-200 range of the curve to determine whether the lever's anti-vibration and anti-locking force B is within the specification range. Extract the peak force value in the 800-1000 range to determine whether the switch response force C is within the specification range. Extract the peak force value in the 300-500 range to determine whether the switch rebound force D is within the specification range. Overall, determine whether the maximum and minimum force values ​​are within the ergonomic comfort force range E.

[0078] VI. Test Pass: After the relevant parameters pass the test, good products are released and defective products are intercepted. The Y-axis motion module drives the carrier from the working position back to the original position, picks up the material, and completes the test.

[0079] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
