Description

Technical Field

[0001] This application relates to the field of button testing technology, and in particular to a testing device and testing method. Background Technology

[0002] Mobile phones and other electronic devices have gradually become indispensable products in daily work and life. Electronic devices typically have buttons for user operation. The feedback from these buttons directly affects the overall performance of the device. Therefore, button testing is a crucial aspect of the design process.

[0003] Currently, as users' demands for experience and functionality continue to increase, devices that test buttons have limited testing capabilities and low testing efficiency, which can no longer meet testing needs. Summary of the Invention

[0004] This application provides a testing device and a testing method that can test buttons with different functions and has high testing efficiency.

[0005] This application provides a testing device for testing at least one of the pressing force, sliding force, and magnetic attraction force of a button. The testing device includes: a carrier frame, a first support frame, a second support frame, a third support frame, a first sensor, and a testing module. The first sensor is a force sensor.

[0006] The first support frame is fixed to the carrier frame, and the first, second, and third support frames are arranged sequentially along the X-axis. The second support frame is slidably connected to the first support frame, and the third support frame is slidably connected to the second support frame. The first sensor is connected to the third support frame. The test module is connected to the first sensor. The test module includes at least one of a pressing test piece, a sliding test piece, and a test fixture. The sliding test piece has a convex arc-shaped surface, and the axis of the convex arc-shaped surface is parallel to the first direction. The test fixture is used to fix the first part of the button.

[0007] The second support frame is movable along the second direction, the third support frame is movable along the third direction, the first sensor and the test module are movable along the second direction so that the pressing test piece can apply pressing force to the button, the sliding test piece can apply sliding force to the button through the convex arc surface, and the test fixture drives the first part of the button to move to the second part so that the button generates magnetic attraction force; the first sensor is used to detect the pressing force, the sliding force and the magnetic attraction force; any two of the first direction, the second direction and the third direction are perpendicular to each other.

[0008] It is understandable that the testing equipment can only test one function of the button at a time. That is, pressing the test piece applies pressure to the button, sliding the test piece applies sliding force to the button, and the test fixture moves the first part of the button to the second part to make the button magnetically attract. These processes cannot occur simultaneously on one testing equipment.

[0009] Specifically, the second support frame can move along the second direction, and the third support frame can move along the third direction to adjust the position of the test module so that the test module and the button are opposite each other along the second direction. Any two of the first, second, and third directions are perpendicular to each other. The first direction is the X-axis direction in this specific embodiment, the second direction is the Z-axis direction, and the third direction is the Y-axis direction.

[0010] When the press test piece and the button are opposite each other in the second direction, the first sensor and the press test piece can move in the second direction, so that the press test piece can apply pressing force to the button, and the first sensor is used to detect the pressing force.

[0011] When the sliding test piece and the button are opposite each other along the second direction, the first sensor and the sliding test piece can move along the second direction, and the third support frame can move along the third direction, so that the sliding test piece applies a sliding force to the button through the convex arc surface. The first sensor is used to detect the sliding force.

[0012] The first part of the button is fixed to the test fixture, and the test fixture and the second part of the button are opposite each other along the second direction. The first sensor and the test fixture can move along the second direction. The first part and the second part of the button generate a magnetic attraction force. The first sensor is used to detect the magnetic attraction force.

[0013] In this application, the testing equipment is slidably connected to the first support frame via a second support frame, allowing the second support frame to slide relative to the first support frame in a second direction. A third support frame is slidably connected to the second support frame, allowing the third support frame to slide relative to the second support frame in a third direction. This allows the testing equipment to apply pressure to the button by pressing the test piece, and then test the pressure using a first sensor, ultimately determining whether the first button is qualified based on the pressure applied. Compared to related technologies, the addition of a third support frame that slides relative to the second support frame in a third direction allows for more flexible adjustment of the position of the test piece.

[0014] Furthermore, in this application, the testing equipment is slidably connected to the first support frame via a second support frame, enabling the second support frame to slide relative to the first support frame along a second direction. A third support frame is slidably connected to the second support frame, enabling the third support frame to slide relative to the second support frame along a third direction. This also allows the testing equipment to move a sliding test piece across the button and detect the sliding force via a first sensor, thus achieving the testing of the button's feedback to the sliding force. Moreover, the sliding test piece has a convex arc-shaped surface, the axis of which is parallel to the first direction. The testing equipment applies a sliding force to the button through the convex arc-shaped surface of the sliding test piece. This results in low friction between the sliding test piece and the button, allowing the sliding test piece to slide smoothly along the button and increasing the stability of the test.

[0015] In addition, in this application, the movable properties of the second and third support frames, and the provision of a test fixture that allows the test fixture to connect to a portion of the button, enable the testing device to test the button's adhesive force.

[0016] As can be seen, the testing equipment provided in this application can test the feedback of the button under pressing pressure and sliding force, and can also test the magnetic attraction force of the button, making it highly applicable.

[0017] In some embodiments, the sliding test piece includes a test support rod and a slider. Along the second direction, one end of the test support rod is connected to a first sensor, and the slider is connected to the other end of the test support rod. A convex arc-shaped surface is disposed on the side of the slider opposite to the test support rod. The sliding test piece has a simple structure and facilitates the application of sliding force to the button.

[0018] In some embodiments, the slider includes a sliding wheel connected to the test support rod via a pivot axis parallel to a first direction. The sliding wheel is rotatable about the pivot axis. The outer circumferential surface of the sliding wheel is a convex arc surface. When the sliding wheel contacts the button and applies a sliding force to the button, the sliding wheel can rotate about the pivot axis, thereby reducing the friction between the sliding wheel and the button.

[0019] In some embodiments, the test module further includes a first mounting component, through which a test support rod is connected to a first sensor. One side of the first mounting component is detachably connected to the first sensor, and the test support rod is connected to the other side of the first mounting component. Connecting the test support rod to the first sensor via the first mounting component facilitates assembly. Furthermore, the detachable connection between the first mounting component and the first sensor facilitates the replacement of devices that need to be connected to the first sensor.

[0020] In some embodiments, the pressing test piece is connected to the first sensor via a first mounting member. The pressing and sliding test pieces share the first mounting member, which can save on the number of parts.

[0021] In some embodiments, the testing device further includes a second sensor disposed on a third support frame. The testing fixture includes an extension along a second direction, with the extension and the second sensor facing each other. The second sensor is used to detect the distance between the extension and the second sensor to maintain a target gap between the first and second portions of the button. By ensuring the target gap is maintained between the first and second portions through detection by the second sensor before the first sensor tests the button's magnetic force, the accuracy of the test results can be increased.

[0022] In some embodiments, the test fixture includes a first test plate, one side of which is connected to a first sensor, and the other side of which is used to connect a first portion of the button. Specifically, the first portion of the button can be glued to the first test plate, which is convenient to operate and can improve testing efficiency.

[0023] In some embodiments, the test fixture further includes a second test plate and a test fixing member. The second test plate is disposed on the side of the first test plate opposite to the first sensor. The test fixing member detachably and securely connects the first and second test plates, and the first part of the button can be clamped between the first and second test plates. The test fixing member can be a bolt. When the first part of the button is placed between the first and second test plates, the first and second test plates are connected by the bolt. This method ensures that the first part of the button is reliably connected to the test fixture, increasing the stability of the testing process.

[0024] In some embodiments, one side of the first test plate and one side of the second test plate are rotatably connected, and the other side of the first test plate and the other side of the second test plate are detachably connected by a test fixing member. When it is necessary to clamp the first part of the button, a single person can operate the second test plate to rotate relative to the first test plate, without the need for other personnel to support the second test plate, which can increase the convenience of operation.

[0025] In some embodiments, the test module further includes a second mounting component, through which the first test board is connected to the first sensor. One side of the second mounting component is detachably connected to the first sensor, and the first test board is connected to the other side of the second mounting component. Connecting the first test board to the first sensor via the second mounting component facilitates assembly. The detachable connection between the second mounting component and the first sensor facilitates the replacement of devices connected to the first sensor.

[0026] In some embodiments, the test fixture includes a sliding rod and a gripper. The sliding rod is connected to a first sensor, and the gripper includes a first clamping portion and a second clamping portion, both of which are slidably connected to the sliding rod. Both the first clamping portion and the second clamping portion can slide along the sliding rod to move closer to or further away from each other. When the first clamping portion and the second clamping portion move closer to each other, they can clamp a first portion of the button.

[0027] In some embodiments, the test module further includes a second mounting component, through which the sliding rod is connected to the first sensor. The first sensor is detachably connected to one side of the second mounting component, and the sliding rod is connected to the other side of the second mounting component.

[0028] In some embodiments, the testing device further includes a first driving member, a second driving member, and a third driving member. The body of the first driving member is disposed on a first support frame, and the driving end of the first driving member is disposed on a second support frame. The first driving member is used to drive the second support frame to move along a second direction. The body of the second driving member is disposed on the second support frame, and the driving end of the second driving member is disposed on a third support frame. The second driving member is used to drive the third support frame to move along a third direction. The body of the third driving member is disposed on the third support frame, and the driving end of the third driving member is connected to a first sensor. The third driving member is used to drive the first sensor to move along the second direction. By setting up the first, second, and third driving members, automated operation can be achieved, improving testing efficiency.

[0029] In some embodiments, the first driving element includes a motor or a cylinder. Alternatively, the body of the first driving element includes a rotating rod and a knob, and the driving end of the first driving element includes a driving slider. The rotating rod is disposed on a first support frame, the knob is fixed to the end of the rotating rod, and the driving slider is disposed on a second support frame. The rotating rod and the driving slider are threadedly connected. The knob can drive the rotating rod to rotate, causing the rotating rod to drive the second support frame to move in a second direction via the driving slider.

[0030] The second driving component includes a motor or a cylinder, and the third driving component includes a motor or a cylinder.

[0031] In some embodiments, the first support frame includes a first support plate and a first slide rail, the first slide rail being disposed on opposite sides of the first support plate along its width direction. The second support frame includes a second support plate, a second slide rail, a sliding member, and a limiting member. The third support frame includes a third support plate and a transition module.

[0032] Along the first direction, the first support plate, the second support plate and the third support plate are arranged in sequence. The sliding member is set on the side of the second support plate facing the first support plate. The sliding member is slidably connected to the first slide rail. The two sides of the limiting member are respectively connected to the first slide rail and the sliding member to limit the second support frame.

[0033] The second slide rail is located on the side of the second support plate facing the third support plate, and the adapter module is located on the side of the third support plate facing the second support plate. The adapter module is slidably connected to the second slide rail.

[0034] A second aspect of this application provides a testing method for testing the magnetic attraction force of a first button using a testing device. The first button includes a first part and a second part. The first part includes a flexible circuit board, a first armature, and an electromagnet, with the electromagnet and the flexible circuit board fixed to opposite sides of the first armature. The second part includes a second armature. The testing device includes a third support frame, a first sensor, and a testing fixture. The first sensor is connected to the third support frame, and the testing fixture is connected to the first sensor. The first sensor and the testing fixture are movable along a second direction. The first part is fixed to the testing fixture.

[0035] The testing method includes: moving the first sensor and the test fixture along the second direction, so that the test fixture drives the first part to move along the second direction, so that there is a target gap between the electromagnet and the second armature.

[0036] After energizing the electromagnet through the flexible circuit board and the first armature, the magnetic attraction force between the electromagnet and the second armature is obtained.

[0037] The first button is judged to be qualified based on its magnetic attraction force.

[0038] The testing method provided in this application can detect the magnetic attraction force of the first button, thereby determining whether the first button is qualified, which can help R&D personnel determine the pass rate of the first button.

[0039] In some embodiments, the testing apparatus further includes a second sensor disposed on a third support frame, and the testing fixture includes an extension. Along a second direction, the extension and the second sensor are opposite each other.

[0040] The first sensor and the test fixture are moved along a second direction, causing the test fixture to move the first part along the second direction, so that a target gap is formed between the electromagnet and the second armature. Specifically, this includes: moving the first sensor and the test fixture downwards, causing the test fixture to move the first part closer to the second part, so that the electromagnet and the second armature come into contact with each other.

[0041] The first distance between the extension detected by the second sensor and the second sensor is obtained when the electromagnet and the second armature are in contact with each other.

[0042] The first sensor and the test fixture are moved upward, causing the test fixture to move the first part away from the first part, so that a gap appears between the electromagnet and the second armature.

[0043] When a gap occurs between the electromagnet and the second armature, the second sensor detects the extension and the second distance between the second sensor.

[0044] When the difference between the first distance and the second distance is the target gap between the electromagnet and the second armature, the first sensor and the test fixture are stopped moving so that the electromagnet and the second armature maintain the target gap.

[0045] By incorporating a second sensor and an extension, a target gap can be maintained between the electromagnet and the second armature. This target gap is the gap that the first button actually needs to maintain when applied to an electronic device. This increases the accuracy of testing the magnetic attraction force between the electromagnet and the second armature.

[0046] In some embodiments, the testing equipment further includes a first support frame and a second support frame. The second support frame is slidably connected to the first support frame, and a third support frame is slidably connected to the second support frame.

[0047] Before moving the first sensor and test fixture downwards, the test method also includes:

[0048] The second support frame is moved along the second direction, and / or the third support frame is moved along the third direction, so that the first part and the second part are opposite each other along the second direction.

[0049] In this testing method, the testing equipment is slidably connected to the first support frame via a second support frame, allowing the second support frame to slide relative to the first support frame in a second direction. Similarly, a third support frame is slidably connected to the second support frame, allowing the third support frame to slide relative to the second support frame in a third direction. This enables the test fixture to move quickly to the appropriate position, thereby rapidly adjusting the relative position of the first and second parts of the button to the desired state, increasing testing efficiency.

[0050] A third aspect of this application provides a testing method for testing a second button, which is a solid-state button, using a testing device. The testing device includes: a first support frame, a second support frame, a third support frame, a first sensor, and a sliding test piece.

[0051] The second support frame is slidably connected to the first support frame, and the third support frame is slidably connected to the second support frame. The first sensor is connected to the third support frame. The sliding test piece is connected to the first sensor.

[0052] The test method includes: moving the second support frame along the second direction, and / or moving the third support frame along the third direction, so that the sliding test piece and the second button are opposite each other along the second direction.

[0053] The first sensor and the sliding test piece are moved along the second direction, so that the sliding test piece applies pressure to the second button.

[0054] The third support frame moves along the third direction, causing the first sensor and the sliding test piece to move along the third direction, so that the pressing force applied by the sliding test piece to the second button becomes the sliding force.

[0055] The sliding force detected by the first sensor is obtained, and a time-sliding force correspondence is established based on the change of sliding force over time.

[0056] Based on the relationship between time and sliding force, determine whether the second button is qualified.

[0057] The testing method provided in this application, through a sliding connection between the third and second support frames, allows the sliding test piece to apply a sliding force to the second button. It can detect the feedback of the second button when subjected to this sliding force, thereby determining whether the second button is qualified. This facilitates researchers in assessing the pass rate of the second button. In this testing method, the testing equipment is slidably connected to the first and second support frames, enabling the second support frame to slide relative to the first support frame in a second direction. Similarly, the third support frame is slidably connected to the second support frame, enabling the third support frame to slide relative to the second support frame in a third direction. This allows the sliding test piece to move quickly to the appropriate position, increasing testing efficiency.

[0058] In some embodiments, moving the third support frame along a third direction causes the first sensor and the sliding test piece to move along the third direction, so that the pressing force applied by the sliding test piece to the second button becomes a sliding force. Specifically, this includes:

[0059] The third support frame moves at a constant speed along the third direction, causing the first sensor and the sliding test piece to move at a constant speed along the third direction, so that the pressing force applied by the sliding test piece to the second button becomes a constant sliding force.

[0060] In some embodiments, moving the third support frame along a third direction causes the first sensor and the sliding test piece to move along the third direction, so that the pressing force applied by the sliding test piece to the second button becomes a sliding force. Specifically, this includes:

[0061] The second support frame moves along a third direction with a certain acceleration, which in turn causes the first sensor and the sliding test piece to move along a third direction with a certain acceleration, so that the pressing force applied by the sliding test piece to the second button becomes a sliding force with acceleration.

[0062] In some embodiments, while the first sensor and the sliding test piece move at a constant speed along a third direction, the first sensor and the sliding test piece gradually move downwards, or the first sensor and the sliding test piece gradually move upwards, so that the sliding force gradually increases or gradually decreases.

[0063] A fourth aspect of this application provides a testing method for testing a first button, which is a mechanical button, using a testing device. The testing device includes: a first support frame, a second support frame, a third support frame, a first sensor, and a pressing test piece.

[0064] The second support frame is slidably connected to the first support frame, and the third support frame is slidably connected to the second support frame. The first sensor is connected to the third support frame. The pressure test piece is connected to the first sensor.

[0065] The testing methods include:

[0066] The second support frame is moved along the second direction, and / or the third support frame is moved along the third direction, so that the pressing test piece and the first button are opposite each other along the second direction.

[0067] The first sensor and the pressure test piece are moved along the second direction, so that the pressure test piece applies a pressing force to the first button.

[0068] The pressing force detected by the first sensor is obtained, and a time-pressure value correspondence is established based on the change of pressing force over time.

[0069] In the time-pressure value correspondence, the first pressure value when the first button responds and the second pressure value when the first button resets are obtained. The first and second pressure values ​​are used to determine whether the first button is qualified.

[0070] The testing method provided in this application can detect the feedback when a first button is pressed, thereby determining whether the first button is qualified, which facilitates R&D personnel in judging the pass rate of the first button. In this testing method, the testing equipment is slidably connected to the first support frame via a second support frame, enabling the second support frame to slide relative to the first support frame in a second direction. A third support frame is slidably connected to the second support frame, enabling the third support frame to slide relative to the second support frame in a third direction. This allows the pressed test piece to move quickly to the corresponding position, increasing testing efficiency.

[0071] In some embodiments, the first sensor and the pressure test element are moved along a second direction, causing the pressure test element to apply a pressing force to the first button. Specifically, this includes:

[0072] The first sensor and the pressure test piece are gradually moved downwards, causing the pressure applied by the pressure test piece to the first button to gradually increase.

[0073] The first sensor and the pressure test piece are gradually moved upward, so that the pressure applied by the pressure test piece to the first button gradually decreases.

[0074] In some embodiments, the first sensor and the pressure test element are moved along a second direction, causing the pressure test element to apply a pressing force to the first button. Specifically, this includes:

[0075] The first sensor and the pressure test piece are gradually moved downwards, causing the pressure applied by the pressure test piece to the first button to gradually increase.

[0076] The first sensor and the pressure test piece are stopped moving and held for a set time, so that the pressing force remains constant within the set time.

[0077] The first sensor and the pressure test piece are gradually moved upward, so that the pressure applied by the pressure test piece to the first button gradually decreases. Attached Figure Description

[0114] The electronic device 2000 includes a body 10 and a display screen 20, which can be a rigid display screen 20 or a flexible display screen 20. The display screen 20 includes a display surface and a mounting surface, which are arranged opposite to each other. The display surface is used to display text, images, and videos, etc. The display screen 20 is mounted on the body 10, and the mounting surface is fixedly connected to the body 10, with the display surface facing away from the body 10.

[0115] The display screen 20 can specifically be: an organic light-emitting diode (OLED) display screen 20, an active-matrix organic light-emitting diode (AMOLED) display screen 20, a mini organic light-emitting diode (MLED) display screen 20, a micro organic light-emitting diode (MOLED) display screen 20, a quantum dot light-emitting diode (QLED) display screen 20, etc.

[0116] The main body 10 includes a housing 30, a main circuit board 40, a battery 50, a first button 60, and a second button 70. The main circuit board 40 and the battery 50 are both installed inside the housing 30. The first button 60 and the second button 70 are both installed inside the housing 30, with a portion of the first button 60 and a portion of the second button 70 located inside the housing 30 and electrically connected to the main circuit board 40. The other portions of the first button 60 and the second button 70 are located outside the housing 30 for user operation.

[0117] In this embodiment, the outer casing 30 includes a middle frame 31 and a rear cover 32. The middle frame 31 includes a middle plate 33 and a frame 34. The frame 34 is rectangular, and the annular space enclosed by the frame 34 is the receiving cavity 37. The frame 34 includes an inner surface 35 and an outer surface 36 facing away from each other. The outer surface 36 is part of the outer appearance surface of the outer casing 30, and the inner surface 35 is the cavity wall surface of the receiving cavity 37. The middle plate 33 is fixed inside the receiving cavity 37, and the middle plate 33 is fixedly connected to the inner surface 35 of the frame 34. The main circuit board 40 and the battery 50 are both installed inside the receiving cavity 37, and the middle plate 33 can support the main circuit board 40 and the battery 50. The rear cover 32 is fixed to the frame 34, and the rear cover 32 can close the receiving cavity 37. The display screen 20 is installed on the side of the frame 34 opposite to the rear cover 32.

[0118] The middle frame 31 is provided with a first mounting hole 38 and a second mounting hole 39, which are arranged sequentially along the extension direction of the middle frame 31. The first mounting hole 38 and the second mounting hole 39 may or may not be connected. Both the first mounting hole 38 and the second mounting hole 39 penetrate the inner surface 35 and the outer surface 36 of the frame 34, and both the first mounting hole 38 and the second mounting hole 39 communicate with the receiving cavity 37. The first mounting hole 38 is used to install the first button 60, and the second mounting hole 39 is used to install the second button 70.

[0119] refer to Figure 3 , Figure 3 yes Figure 1 The diagram shows the split structure of the first button.

[0120] The first button 60 can be a mechanical button, and can be a volume button or a power button. The first button 60 includes a first part 61 and a second part 62. The first part 61 includes an electromagnet 63, a first armature 64 and a flexible circuit board 65, and the second part 62 includes a second armature 69.

[0121] Please refer to the above. Figure 4 , Figure 4 yes Figure 3 The diagram shows the structure of the electromagnet for the first button.

[0122] The electromagnet 63 includes a magnetic core 66, a coil 67, and a magnetic shielding frame 68. The coil 67 is wound around the outer periphery of the magnetic core 66. The magnetic shielding frame 68 is a frame-shaped structure with an opening on one side. The material of the magnetic shielding frame 68 can be any one of silicon steel, FeNi alloy, FeCo alloy, FeMn alloy, and FeSi alloy. The magnetic core 66 and the coil 67 are fixed inside the magnetic shielding frame 68. The two ends of the first armature 64 and the two ends of the second armature 69 are fixedly connected, forming a receiving space between the first armature 64 and the second armature 69. The electromagnet 63 is installed in the receiving space. The magnetic shielding frame 68 and its sidewall opposite to its opening are fixed to the first armature 64, and the opening of the magnetic shielding frame 68 faces the second armature 69.

[0123] Please refer to the above. Figure 5 , Figure 5 yes Figure 1 A structural schematic diagram of the first button of the electronic device shown from another perspective.

[0124] There is a gap L between the electromagnet 63 and the second armature 69. One side of the flexible circuit board 65 is fixed to the side of the first armature 64 opposite to the second armature 69, and the other side of the flexible circuit board 65 is used for electrical connection with the main circuit board 40.

[0125] The first button 60 may also include a keycap (not shown), which is located on the side of the flexible circuit board 65 opposite to the first armature 64. The keycap also passes through the flexible circuit board 65 and is connected to the first armature 64. The keycap is located outside the electronic device 2000 and is used for user operation. Specifically, when the user presses the keycap, the first armature 64 bends and deforms downwards. When the sensor (not shown) detects that the deformation of the first armature 64 reaches a certain level, the battery 50 supplies power to the flexible circuit board 65 via the main circuit board 40, thereby energizing the electromagnet 63. After the electromagnet 63 is energized, the electromagnet 63 and the second armature 69 attract each other. Because the second armature 69 is a rigid part, it will not deform, while the first armature 64 can undergo elastic deformation. Under the action of magnetic attraction, the electromagnet 63 moves downwards, causing the first armature 64 to continue to bend and deform downwards. When the user releases the keycap, the first armature 64 deforms upwards to reset, giving the user feedback that the key was pressed successfully.

[0126] If the pressing force and feedback force are too small, users will be unable to determine whether the press was successful. If the pressing force and feedback force are too large, users will need to apply more force to press successfully, resulting in a poor tactile feel. Typically, the pressing force and feedback force are set between 1N and 4N. This setting makes it easier for users to determine whether the press was successful while reducing the difficulty of pressing the first button and improving the pressing feel.

[0127] During the machining of the first button 60, errors in the winding of the coil 67 around the magnetic core 66 may result in the coil 67 on one side of the magnetic core 66 being higher, while the coil 67 on the other side of the magnetic core 66 is lower. Errors in the machining and assembly of the magnetic shielding frame 68 may result in a larger height difference between one side of the magnetic shielding frame and the magnetic core 66, and a smaller height difference between the other side of the magnetic shielding frame 68 and the magnetic core 66. Both of these situations will ultimately lead to an imbalance in the width of the gap L between the electromagnet 63 and the second armature 69. This imbalance in the gap L between the electromagnet 63 and the second armature 69 directly affects the magnetic attraction between them. The magnetic attraction between the electromagnet 63 and the second armature 69 directly affects the amount of pressure required to press the first button 60, and also affects the amount of feedback force required to press the first button 60.

[0128] For the reasons mentioned above, to ensure that the feedback force and the pressing force when the first button 60 responds are within the target range when it is pressed, it is usually necessary to test the feedback force and the pressing force when the first button 60 responds. It is also necessary to test the magnetic attraction force between the electromagnet 63 and the second armature 69. Whether the magnetic attraction force between the electromagnet 63 and the second armature 69 is qualified is used to determine whether the first button 60 is qualified.

[0129] The second button 70 can be a solid-state button, which refers to a button that has no physical moving parts and is activated by touch. When a user touches the second button 70 and slides their finger along the length of the electronic device 2000, the button is activated and executes the corresponding command. For example, when a user takes a photo with the camera, the second button 70 can be used to adjust the camera's focus. When browsing video or text pages, the second button 70 can be used to turn pages. When browsing a map, the second button 70 can zoom in and out. When listening to music, the second button 70 can be used to switch songs. The sliding force when operating the solid-state button also needs to be detected to ensure that the sliding force is within the target range.

[0130] refer to Figure 6 and Figure 8 , Figure 6 This is a schematic diagram of the structure of the testing equipment provided in the embodiments of this application. Figure 8 yes Figure 6 A schematic diagram of the test equipment shown from another perspective.

[0131] The structure of the test device 1000 used to test the first button 60 and the second button 70 is described below.

The third support frame 500 is slidably connected to the second support frame 400. The fourth support frame 900 is slidably connected to the third support frame 500. The body 10 of the first driving member 600 is fixed to the first support frame 300, and the driving end of the first driving member 600 is fixed to the second support frame 400. The first driving member 600 is used to drive the second support frame 400 to move along the Z-axis. The body 10 of the second driving member 610 is fixed to the second support frame 400, and the driving end of the second driving member 610 is fixed to the third support frame 500. The second driving member 610 is used to drive the third support frame 500 to move along the Y-axis.

[0134] The body 10 of the third drive unit 620 is fixed to the third support frame 500. One end of the first sensor 700 is connected to the drive end of the third drive unit 620, and the test module 100 is connected to the other end of the first sensor 700. The third drive unit 620 is used to drive the first sensor 700 and the test module 100 to move along the Z-axis. The first sensor 700 can be a force sensor, and the test module 100 can apply force to the button. The first sensor 700 can include an elastic element and a pressure-sensitive element, etc. The spring can transmit the received force to the pressure-sensitive element to test the magnitude of the force. The body 10 of the fourth drive unit 630 is fixed to the third support frame 500, and the drive end of the fourth drive unit 630 is fixed to the fourth support frame 900. The fourth drive unit 630 is used to drive the fourth support frame 900 to move along the Z-axis. The second sensor 800 is fixed to the fourth support frame 900, and the fourth support frame 900 can drive the second sensor 800 to move along the Z-axis. The second sensor 800 can be a distance sensor, and the second sensor 800 can detect the displacement change of the button.

[0135] refer to Figure 7 , Figure 7 yes Figure 6 The diagram shows the structural connection between the carrier frame, the first support frame, and the second support frame of the test equipment shown.

[0136] In this embodiment, the support frame 200 is rectangular in shape and includes a base 201, a first pad (not shown), a second pad (not shown), and a support column 204. The base 201, the first pad, and the second pad are all rectangular plates, and are sequentially stacked and fixed along the Z-axis. The thickness directions of the base 201, the first pad, and the second pad are parallel to the Z-axis. The top surface of the base 201 contacts the bottom surface of the first pad, and the top surface of the first pad contacts the bottom surface of the second pad. The bottom surface of the base 201 can contact the ground or similar surfaces. The support column 204 is fixed to the top surface of the base 201, and there is a gap between the support column 204 and the first pad. The base 201 and the first pad, the first pad and the second pad, and the support column 204 and the base 201 can all be fixed by welding or fastener connection. Fasteners can include screws or bolts. In other embodiments, the support frame 200 may only include the base 201, that is, the first pad and the second pad may not be provided. Alternatively, the support frame 200 may include the base 201 and the first pad, that is, the second pad may not be provided.

[0137] The first support frame 300 includes a first support plate 310, which is a cuboid plate. The thickness direction of the first support plate 310 is parallel to the X-axis direction, the length direction of the first support plate 310 is parallel to the Z-axis direction, and the width direction of the first support plate 310 is parallel to the Y-axis direction.

[0138] The first support frame 300 is fixed to the carrier frame 200. Specifically, the bottom end of the first support plate 310 is fixed to the top surface of the second pad, and the top end of the first support plate 310 extends away from the second pad. It is understood that when the carrier frame 200 only includes the base 201, the bottom end of the first support plate 310 is fixed to the top surface of the base 201. When the carrier frame 200 includes both the base 201 and the first pad, the bottom end of the first support plate 310 is fixed to the top surface of the first pad.

[0139] Continue to refer to Figure 7 The sliding connection relationship between the second support frame 400 and the first support frame 300 is described below.

[0140] Specifically, the first support frame 300 also includes two first slide rails 320, which are respectively fixed to opposite sides of the first support plate 310 along its width direction. Each first slide rail 320 has a first guide surface 321, which is inclined relative to the surface of the first support plate 310, and the included angle between the first guide surface 321 and the surface of the first support plate 310 is an obtuse angle. The first guide surface 321 is recessed with a limiting groove (not shown in the figure), which is used to limit the second support frame 400.

[0141] The second support frame 400 includes a second support plate 410, a sliding connector 420, and a limiting member 430. The second support plate 410 is a cuboid plate, and its thickness direction is parallel to the X-axis direction. Two sliding connectors 420 are fixed to the surface of the second support plate 410 and are spaced apart along the Y-axis direction. Each sliding connector 420 has a limiting hole (not shown) that penetrates the sliding connector 420 along the Y-axis direction.

[0142] Along the X-axis, a first support plate 310 and a second support plate 410 are stacked. The surface of the second support plate 410 facing away from the second slide rail 440 is opposite to one side surface of the first support plate 310, and two sliding connectors 420 are slidably connected to the two first slide rails 320 respectively. Specifically, the two sliding connectors 420 are in contact with the first guide surfaces 321 of the two first slide rails 320 respectively. The first slide rails 320 can play a guiding role, and the first guide surfaces 321 are inclined surfaces, which can also prevent the sliding connectors 420 from disengaging from the first slide rails 320. The sliding connectors 420 can slide along the first slide rails 320, so that the entire second support frame 400 can move along the Z-axis. After the second support frame 400 moves into place, the limiting member 430 can pass through the limiting hole and the limiting groove to limit the second support frame 400 and prevent the second support frame 400 from becoming unstable.

[0143] refer to Figure 8 , Figure 8 yes Figure 6 The diagram shows a cross-sectional view of the connection between the first support frame, the second support frame, and the first drive unit of the test equipment. The following describes how the first drive unit 600 drives the second support frame 400 to move relative to the first support frame 300 along the Z-axis.

[0144] Specifically, the first support plate 310 has a recessed mounting groove 311 on its surface facing the second support plate 410. The mounting groove 311 is used to mount the first driving component 600. The first driving component 600 includes a rotating rod 601, a knob 602, and a driving slider 603. The rotating rod 601 and the knob 602 form the body 10 of the first driving component 600, and the driving slider 603 is the driving end of the first driving component 600. The outer circumferential surface of the rotating rod 601 is provided with external threads. The driving slider 603 is provided with a driving hole 604, which penetrates the driving slider 603 along the Z-axis direction. The inner wall surface of the driving hole 604 is provided with internal threads.

[0145] The body 10 of the first driving component 600 is fixed to the first support frame 300, and the driving end of the first driving component 600 is fixed to the second support frame 400. Specifically, the rotating rod 601 is disposed in the mounting groove 311, and the axial direction of the rotating rod 601 is parallel to the Z-axis direction. The bottom end of the rotating rod 601 extends out of the bottom end of the first support plate 310 and is connected to the second pad block, while the top end of the rotating rod 601 extends out of the top end of the first support plate 310. The knob 602 is fixed to the top end of the rotating rod 601. The driving slider 603 is fixed to the surface of the second support plate 410 away from the second slide rail 440. The driving slider 603 extends into the mounting groove 311, and the rotating rod 601 passes through the driving hole 604, with the external thread of the rotating rod 601 connected to the internal thread of the driving hole 604. The first driving component 600 can drive the second support frame 400 to move along the Z-axis. Specifically, the tester can rotate the knob 602, causing the knob 602 to drive the rotating rod 601 to rotate around its axis. The external thread of the rotating rod 601 and the internal thread of the driving hole 604 are engaged, causing the rotating rod 601 to drive the driving slider 603 to move along the Z-axis, thereby causing the driving slider 603 to drive the second support frame 400 along the Z-axis.

[0146] In other embodiments, the first driving component 600 can be a motor or a cylinder, and the motor can be a linear motor or a voice coil motor. When the first driving component 600 is a motor, the motor body 10 is fixed to the first support plate 310, and the motor drive shaft is fixed to the second support plate 410. When the first driving component 600 is a cylinder, the cylinder body is fixed to the first support plate 310, and the cylinder connecting rod is fixed to the second support plate 410.

[0147] refer to Figure 9 and Figure 10 , Figure 9 yes Figure 6 A cross-sectional view of the connection between the second support frame, the third support frame, and the second drive component of the test equipment shown. Figure 10 yes Figure 9 An enlarged schematic diagram at point A. The following describes the sliding connection relationship between the third support frame 500 and the second support frame 400.

[0148] The second support frame 400 also includes a second slide rail 440. The second slide rail 440 is fixed to the surface of the second support plate 410 opposite to the sliding connector 420. The second slide rail 440 is elongated and has a convex cross-section. Guide grooves 441 are provided on both opposite sides of the second slide rail 440 along the Z-axis.

[0149] The third support frame 500 includes a third support plate 510, a connector 520, and an adapter module 530. The third support plate 510 is stacked on the side of the second support plate 410 away from the first support plate 310. Both the third support plate 510 and the connector 520 are cuboid plates, and their thickness directions are parallel to the X-axis. The volume of the connector 520 is smaller than that of the third support plate 510, and the connector 520 is fixed to the surface of the third support plate 510 facing the second support plate 410. The adapter module 530 includes a first adapter 531, a second adapter 532, a third adapter 533, a connector 534, and a guide slide 535. One side of the first adapter 531 is fixedly connected to the connector 520, the other side of the first adapter 531 is fixedly connected to one side of the second adapter 532, and the other side of the second adapter 532 is fixedly connected to one side of the third adapter 533. Both sides of the connector 534 are connected to the other side of the third adapter 533 and the guide slide 535, respectively. The first adapter 531 and the connecting member 520, the first adapter 531 and the second adapter 532, and the second adapter 532 and the third adapter 533 can all be fixed by welding or fastener connection. In other embodiments, the first adapter 531, the second adapter 532, and the third adapter 533 can also be integrally formed components. The specific structure of the first adapter 531, the second adapter 532, and the second adapter 532 can be plate-like or other structures; this application does not impose specific limitations, as long as it serves a connecting function.

[0150] The third support frame 500 is slidably connected to the second support frame 400 via an adapter module 530. Along the Z-axis, the third adapter 533 is stacked on the second slide rail 440, and covers the guide groove 441 of the second slide rail 440. The guide member 535 is installed within the guide groove 441 of the second slide rail 440 and can slide within the guide groove 441. One side of the connector 534 is fixed to the third adapter 533, and the other side of the connector 534 extends into the guide groove 441 and is fixedly connected to the guide member 535. Specifically, the connector 534 can be a bolt, and the guide member 535 can be a nut. The shank of the bolt passes through the third adapter 533, and the nut can be tightened onto the shank of the bolt. The head of the bolt can abut against the side of the third adapter 533 opposite to the second slide rail 440. It is understood that there can be two adapter modules 530, which respectively slide the top and bottom of the third support plate 510 to the top and bottom of the second slide rail 440, so that the third support frame 500 slides more smoothly. In other embodiments, there can also be one adapter module 530.

[0151] Continue to refer to Figure 9The following describes how the second drive unit 610 drives the third support frame 500 to move relative to the second support frame 400 along the Y-axis.

[0152] The body 10 of the second driving component 610 is fixed to the second support frame 400, and the driving end of the second driving component 610 is fixed to the third support frame 500. Specifically, the body 10 of the second driving component 610 is fixed to the second support plate 410, and the driving end of the second driving component 610 is fixed to the third support plate 510. The second driving component 610 can be a motor or a cylinder, etc. The motor can be a linear motor or a voice coil motor. When the second driving component 610 is a motor, the body 10 of the second driving component 610 is the motor body 10, and the driving end of the second driving component 610 is the motor drive shaft. When the second driving component 610 is a cylinder, the body 10 of the second driving component 610 is the cylinder body, and the driving end of the second driving component 610 is the cylinder connecting rod. The second driving component 610 can drive the third support frame 500 to move along the Y-axis direction. Specifically, the body 10 of the second driving member 610 is activated, driving the driving end of the second driving member 610 to move along the Y-axis direction, so that the driving end of the second driving member 610 drives the third support frame 500 to move along the Y-axis direction.

[0153] refer to Figure 11 , Figure 11 yes Figure 6 The diagram shows the structural connection of the third support frame 500, the third drive component 620, the first sensor 700, and the test module 100 in the test equipment shown. The connection relationship between the third support frame 500, the third drive component 620, the first sensor 700, and the test module 100 is described below.

[0157] The following describes the specific details of the test module 100, including the press test component 112, the slide test component 113, and the test fixture 122, in this embodiment. Specifically, the test module 100 includes a first test component 110 and a second test component 120, both of which are detachably connected to the first sensor 700. The first test component 110 applies a force along the Z-axis to the button under test, or applies a sliding force along the Y-axis to the button under test. The second test component 120 connects to the button under test. When a press or slide test is required, the first test component 110 can be mounted on the bottom of the first sensor 700.

The slider 115 has a convex arc-shaped surface 116, the axis of which is parallel to the X-axis, and the curve of which extends along the Y-axis. The sliding element 115 can be a sliding wheel 117. The sliding wheel 117 is rotatably connected to the test support rod 114 through a rotating shaft. The sliding wheel 117 can rotate around the axis of the rotating shaft. The axis of the sliding wheel 117 is parallel to the X-axis direction. The outer peripheral surface of the sliding wheel 117 is a convex arc surface 116.

[0159] In other embodiments, refer to Figure 13 The sliding member 115 can be an arc-shaped member 118. The top of the arc-shaped member 118 is fixed to the bottom of the test support rod 114. The bottom of the arc-shaped member 118 is provided with a convex arc-shaped surface 116, and the axis of the convex arc-shaped surface 116 is parallel to the X-axis direction. It can be understood that an arc surface refers to a curved surface formed by rotating a curve around an axis. Therefore, in this embodiment, the axis of the convex arc-shaped surface 116 refers to the axis around which its curve revolves.

[0160] It is understood that in this embodiment, the pressing test piece 112 and the sliding test piece 113 can share a single first mounting piece 111, meaning that both the pressing test piece 112 and the sliding test piece 113 are connected to the first mounting piece 111. In other embodiments, there are two first mounting pieces 111, with the pressing test piece 112 connected to one of them and the sliding test piece 113 connected to the other. Both first mounting pieces 111 can be detachably connected to the bottom of the first sensor 700. When testing the pressing force of a button, the first mounting piece 111 connected to the pressing test piece 112 can be mounted on the first sensor 700. When testing the sliding force of a button, the first mounting piece 111 connected to the sliding test piece 113 can be mounted on the first sensor 700.

[0161] refer to Figure 14The second test assembly 120 includes a second mounting member 121 and a test fixture 122. The second mounting member 121 may be rod-shaped, and its top is detachably connected to the bottom of the first sensor 700. The test fixture 122 includes a first test plate 123, a second test plate 124, and a test fixing member 125. One side surface of the first test plate 123 is fixedly connected to the bottom of the second mounting member 121. Along the Z-axis, the first test plate 123 includes an extension 126 that extends to a point spaced apart from the bottom of the second sensor 800. The second test plate 124 is stacked on the side surface of the first test plate 123 facing away from the second mounting member 121. The first test plate 123 and the second test plate 124 are detachably fixed by the test fixing member 125. The test fixing member 125 may be a bolt. The gap between the first test plate 123 and the second test plate 124 is used to clamp the button to be tested.

[0162] refer to Figure 15 , Figure 15 yes Figure 14 This is a structural schematic diagram of the test fixture of the second test component shown from another perspective.

[0163] There can be four test fixtures 125. The four test fixtures 125 respectively fix and connect the four corners of the first test plate 123 and the four corners of the second test plate 124, which can increase the stability of the connection between the first test plate 123 and the second test plate 124.

[0164] In other embodiments, refer to Figure 16 , Figure 16 yes Figure 6 The diagram shows another structural schematic of the second test component of the test module of the test equipment shown. One side of the first test plate 123 and one side of the second test plate 124 are rotatably connected, and the other side of the first test plate 123 and the other side of the second test plate 124 are detachably connected by test fixing members 125. There can be two test fixing members 125, which respectively fix two corners of the first test plate 123 and two corners of the second test plate 124. Thus, when it is necessary to clamp the button to be tested, the second test plate 124 is rotated relative to the first test plate 123, so that the second test plate 124 and the first test plate 123 are in an open state. Then, the button to be tested is placed on the side of the first test plate 123 away from the second mounting member 121. Then, the second test plate 124 is rotated so that it cooperates with the first test plate 123, clamping the button to be tested between the first test plate 123 and the second test plate 124. Finally, the test fixing members 125 are used to fix the first test plate 123 and the second test plate 124 together.

[0165] In other embodiments, the test fixture 122 may consist only of a first test plate 123, with one side surface of the first test plate 123 fixedly connected to the bottom of the second mounting member 121. The surface of the first test plate 123 facing away from the second mounting member 121 is used to connect the button to be tested. Specifically, the button to be tested can be glued and fixed to the surface of the first test plate 123 facing away from the second mounting member 121.

[0166] In other embodiments, refer to Figure 17 and Figure 18 , Figure 17 yes Figure 6 The diagram shows another structural schematic of the second test component of the test module of the test equipment shown. Figure 18 yes Figure 17 The diagram shows another structural configuration of the second test component. The test fixture 122 may include a first test drive (not shown), a second test drive (not shown), a second mounting bracket, a sliding rod 127, and a gripper 128. The sliding rod 127 is fixed to the bottom of the second mounting bracket 121. The gripper 128 includes a first clamping portion 129, a second clamping portion 130, and an extension portion 126. Both the first clamping portion 129 and the second clamping portion 130 are slidably connected to the sliding rod 127. The body 10 of the first test drive is fixed to the second mounting bracket 121, and the drive end of the first test drive is fixed to the first clamping portion 129. The body 10 of the second test drive is fixed to the second mounting bracket 121, and the drive end of the second test drive is fixed to the second clamping portion 130. The first test drive member drives the first clamping part 129 to slide along the sliding rod 127, and the second test drive member drives the second clamping part 130 to slide along the sliding rod 127, so that the first clamping part 129 and the second clamping part 130 can move closer to each other or further apart. When the first clamping part 129 and the second clamping part 130 move closer to each other, they can clamp the button to be tested; when the first clamping part 129 and the second clamping part 130 move further apart, they can release the button to be tested. The extension part 126 is fixed to the first clamping part 129, and along the Z-axis direction, the extension part 126 extends to a distance from the bottom of the second sensor 800.

[0167] refer to Figure 19 , Figure 19 yes Figure 6 The diagram shows the structural connection between the third support frame 500, the fourth support frame 900, the fourth drive component 630, and the second sensor in the test equipment shown. The connection relationship between the third support frame 500, the fourth support frame 900, the fourth drive component 630, and the second sensor 800 is described below.

[0168] The third support frame 500 also includes a second bearing member 550 and a third slide rail 560. Both the second bearing member 550 and the third slide rail 560 are fixed to the surface of the third support plate 510 facing away from the second support plate 410, and are arranged alternately along the Y-axis. The second bearing member 540 and the second bearing member 550 are arranged along the Z-axis. A guide member 561 is provided on the side of the third slide rail 560 facing away from the third support plate 510. The guide member 561 has a guide hole 562, which can be an oblong hole with its major axis parallel to the Z-axis.

[0169] The fourth support frame 900 includes a fourth support plate 910, a sliding plate 920, and a sliding column 930. The sliding plate 920 is fixed to one side surface of the fourth support plate 910, and the sliding column 930 is fixed to one side of the sliding plate 920. A sliding groove is provided on the side surface of the sliding plate 920 facing away from the fourth support plate 910. The fourth support frame 900 is slidably connected to the third support frame 500. Specifically, the fourth support plate 910 is stacked on the side of the third support plate 510 facing away from the second support plate 410, and the sliding groove of the sliding plate 920 is slidably connected to the third slide rail 560. The sliding column 930 extends into the guide hole 562 of the guide member 561. When the sliding plate 920 slides along the third slide rail 560, the sliding column 930 slides within the guide hole 562. When the sliding column 930 abuts against the bottom of the hole wall of the guide hole 562, the sliding plate 920 can stop sliding to prevent excessive movement.

[0170] The body 10 of the fourth driving member 630 is fixed to the second support member 550, and the driving end of the fourth driving member 630 is fixed to the sliding plate 920. The second sensor 800 is fixed to the side surface of the fourth support plate 910 opposite to the sliding plate 920. The fourth driving member 630 can be a motor or a cylinder. The fourth driving member 630 can drive the third sliding module to move along the Z-axis, so that the third sliding module drives the second sensor 800 to move along the Z-axis. In other embodiments, the second support member 550 may be omitted, and the body 10 of the fourth driving member 630 may be directly fixed to the third support plate 510.

[0171] refer to Figure 20 and Figure 21 , Figure 20 This is a flowchart illustrating the feedback of a first button on an electronic device to pressure, as provided in the test method of this application. Figure 21 This is a state diagram of the test device when testing the feedback of the first button of an electronic device in response to pressing pressure. The following describes the process of using the test device 1000 provided in the embodiments of this application to detect the pressing pressure and feedback force of the first button 60. It is understood that when the first button 60 needs to be tested, the first test component 110 is installed on the bottom of the first sensor 700.

[0172] Step S10: Place the electronic device 2000 on top of the support column 204, so that the first button 60 of the electronic device 2000 faces the first test component 110. Specifically, a clamp (not shown) can be used to fix the electronic device 2000 to the top of the support column 204.

[0173] Step S11: Move the second support frame 400 along the second direction, and / or move the third support frame 500 along the third direction, so that the pressing test piece 112 and the first button 60 are opposite each other along the second direction.

[0174] Specifically, the first driving component 600 moves the first test component 110 downward, and the second driving component 610 moves the first test component 110 along the Y-axis, so that the pressing test piece 112 of the first test component 110 and the first button 60 of the electronic device 2000 are opposite each other along the Z-axis. It can be understood that the activation order of the first driving component 600 and the second driving component 610 is not restricted. Specifically, turning the knob 602 causes the rotating rod 601 to rotate, which in turn causes the driving slider 603 to move downward, thereby causing the second support frame 400 to move downward. The third support frame 500, the first test component 110, and the first sensor 700 all move downward synchronously with the second support frame 400 until the convex arc-shaped contact portion of the pressing test piece 112 contacts the keycap of the first button 60. The second drive unit 610 is activated, causing the drive end of the second drive unit 610 to drive the third support frame 500, the first test component 110 and the first sensor 700 to move synchronously along the Y-axis.

[0175] It is understandable that if the first driving component 600 moves the first test component 110 downwards, and the pressing test component 112 is already in contact with the first button 60, then the second driving component 610 does not need to be activated. If the second driving component 610 moves the first test component 110 along the Y-axis, and the pressing test component 112 is already opposite the first button 60, then the first driving component 600 does not need to be activated.

[0176] Step S12: Move the first sensor 700 and the pressure test piece 112 along the second direction, so that the pressure test piece 112 applies a pressing force to the first button 60. Specifically, activate the third drive member 620 to drive the first sensor 700 and the pressure test piece 112 to move along the Z-axis.

[0177] Step S13: Obtain the pressing force detected by the first sensor 700, and establish a time-pressure value correspondence based on the change of pressing force over time. (Reference) Figure 22 and Figure 23 , Figure 22It is the time-pressure value curve of the first button's feedback to changes in pressing pressure. Figure 23 This is a time-pressure curve reflecting the feedback of a fixed pressing force on the first button 60. During the process of the pressing test piece 112 applying pressure to the first button 60, the pressure value is fed back to the first sensor 700. The controller reads the reading from the first sensor 700, which represents the pressing force applied to the first button 60. The controller can generate a time-pressure curve based on the relationship between the pressing force and time.

[0178] Step S14: In the time-pressure value correspondence, obtain the first pressure value when the first button 60 responds and the second pressure value when the first button 60 resets; determine whether the first button 60 is qualified based on the first pressure value and the second pressure value. Specifically, the time-pressure value curve can display the first pressure value when the first button 60 responds, that is, the first pressure value when the first armature 64 of the first button 60 deforms downwards, and can display the second pressure value when the first button 60 resets, that is, the second pressure value when the first armature 64 of the first button 60 deforms upwards to reset. Then, compare the first pressure value with the first standard value, and compare the second pressure value with the second standard value. If the difference between the first pressure value and the first standard value is less than the first parameter, and the difference between the second pressure value and the second standard value is less than the second parameter, then the first button 60 is qualified. If the difference between the first pressure value and the first standard value is greater than or equal to the first parameter, or the difference between the second pressure value and the second standard value is greater than or equal to the second parameter, then the first button 60 is unqualified.

[0179] The first standard value ranges from 3N to 8N, for example, the first standard value can be 3N, 3.5N, 4N, 4.5N, 5N, 5.5N, 6N, 6.5N, 7N, 7.5N, or 8N, etc. The second standard value ranges from 0.5N to 2N, for example, the second standard value can be 0.5N, 1N, 1.5N, or 2N, etc. The first parameter can be 0.5N, and the second parameter can be 0.5N.

[0180] In one specific embodiment, the above method can detect whether the first button 60 is qualified when subjected to a changing pressing force. That is, step S12 specifically includes: gradually moving the first sensor 700 and the pressing test piece 112 downwards, causing the pressing force applied by the pressing test piece 112 to the first button 60 to gradually increase; and gradually moving the first sensor 700 and the pressing test piece 112 upwards, causing the pressing force applied by the pressing test piece 112 to the first button 60 to gradually decrease. At this time, a result such as... Figure 22 The time-pressure curve shown.

[0181] Specifically, the third driving member 620 causes the first sensor 700 and the first test component 110 to gradually move downwards, causing the pressing test component 112 to apply a pressing force to the first button 60, and this pressing force gradually increases. Then, the third driving member 620 causes the first sensor 700 and the first test component 110 to gradually move upwards, causing the pressing force applied to the first button 60 by the pressing test component 112 to gradually decrease.

[0182] In another specific embodiment, the above method can detect whether the first button 60 is qualified when subjected to a fixed pressing force. That is, step S12 specifically includes: gradually moving the first sensor 700 and the pressing test piece 112 downwards, so that the pressing force applied by the pressing test piece 112 to the first button 60 gradually increases; stopping the movement of the first sensor 700 and the pressing test piece 112 and maintaining it for a set time, so that the pressing force remains unchanged within the set time; and gradually moving the first sensor 700 and the pressing test piece 112 upwards, so that the pressing force applied by the pressing test piece 112 to the first button 60 gradually decreases. At this time, a result such as... Figure 23 The time-pressure curve shown.

[0183] Specifically, the third driving component 620 is activated, causing it to move the first sensor 700 and the first test component 110 downwards, thus applying a pressing force to the first button 60 using the pressing test component 112, which gradually increases. Then, the third driving component 620 is stopped for a certain period, so that the pressing force applied by the pressing test component 112 to the first button 60 remains constant. Then, the third driving component 620 is activated again, causing it to move the first sensor 700 and the first test component 110 upwards, thus gradually decreasing the pressing force applied by the pressing test component 112 to the first button 60.

[0184] refer to Figure 24 and Figure 25 , Figure 24 This is a flowchart illustrating the feedback of the second button of the electronic device to the sliding force in the test method provided in this application embodiment. Figure 25 This is a state diagram of the test equipment when testing the feedback of the second button of an electronic device to the sliding force. The following describes the process of detecting the sliding force on the second button 70 using the test equipment provided in the embodiments of this application. It is understood that to detect the response of the second button 70 to the sliding force, the first test component 110 needs to be mounted on the bottom of the first sensor 700. This is described in detail below.

[0185] Step S20: Place the electronic device 2000 on top of the support column 204, such that the second button 70 of the electronic device 2000 faces the first test component 110. Specifically, a clamp (not shown) can be used to fix the electronic device 2000 to the top of the support column 204.

[0186] Step S21: Move the second support frame 400 along the second direction, and / or move the third support frame 500 along the third direction, so that the sliding test piece 113 and the second button 70 are opposite each other along the second direction.

[0187] Specifically, the first driving component 600 moves the first test component 110 downward, and the second driving component 610 moves the first test component 110 along the Y-axis, causing the sliding test piece 113 of the first test component 110 to contact the second button 70 of the electronic device 2000. At this time, the first test component 110 does not apply force to the second button 70. It can be understood that the activation order of the first driving component 600 and the second driving component 610 is not restricted. Specifically, turning the knob 602 causes the knob 602 to drive the rotating rod 601 to rotate, causing the driving slider 603 to move downward, thereby causing the second support frame 400, the third support frame 500, the first test component 110, and the first sensor 700 to move downward synchronously until the sliding wheel 117 of the sliding test piece 113 contacts the keycap of the second button 70.

[0188] It is understandable that if the first driving component 600 moves the first test component 110 downwards and the sliding test component 113 has already contacted the second button 70, then the second driving component 610 does not need to be activated. If the first driving component 600 moves the first test component 110 along the Y-axis and the sliding test component 113 has already contacted the second button 70, then the first driving component 600 does not need to be activated.

[0189] Step S22: Move the first sensor 700 and the sliding test piece 113 along the second direction, so that the sliding test piece 113 applies pressure to the second button 70. Specifically, activate the third drive unit 620 to move the first sensor 700 and the first test component 110 downward, so that the sliding test piece 113 applies pressure to the second button 70.

[0190] Step S23: Move the third support frame 500 along a third direction, causing the first sensor 700 and the sliding test piece 113 to move along the third direction, so that the pressing force applied by the sliding test piece 113 to the second button 70 becomes a sliding force. Specifically, control the second drive member 610 to work, so that the second drive member 610 drives the sliding test piece 113 to slide along the Y-axis direction.

[0191] Step S24: Acquire the sliding force detected by the first sensor 700, and establish a time-sliding force correspondence based on the change of sliding force over time. The controller can read the reading from the first sensor 700, which is the sliding force. (Reference) Figure 26 and Figure 27 , Figure 26 It is the time-sliding force curve of the second button's feedback to a constant sliding force with varying force values. Figure 27 It is the time-pressure curve of the feedback of the second button to a sliding force with a fixed force value and acceleration, and the feedback of a sliding force with a fixed force value and uniform speed. Figure 26 In Chinese, 50g refers to a force of 50 grams, where 100g equals a force of 1 N. 500g / s refers to 500 grams per second, where grams represent the force applied.

[0192] Step S25: Determine whether the second button 70 is qualified based on the time-sliding force correspondence. If the sliding force remains constant or changes smoothly in the time-sliding force curve, the response of the second button 70 is continuous. Conversely, if the sliding force suddenly decreases or increases in the time-sliding force curve, the response of the second button 70 is discontinuous, indicating that the second button 70 is unqualified.

[0193] The sliding test piece 113 can apply a sliding force to the second button 70 by sliding the third support frame 500 and the second support frame 400 together. This allows for the detection of the feedback when the second button 70 is subjected to the sliding force, thus determining whether the second button 70 is qualified. This facilitates the assessment of the pass rate of the second button 70 by R&D personnel. In this testing method, the testing equipment 1000 is slidably connected to the first support frame 300 via the second support frame 400, allowing the second support frame 400 to slide relative to the first support frame 300 in a second direction. Similarly, the third support frame 500 is slidably connected to the second support frame 400, allowing the third support frame 500 to slide relative to the second support frame 400 in a third direction. This enables the sliding test piece 113 to move quickly to the corresponding position, increasing testing efficiency. Furthermore, the sliding test piece 113 has a convex arc surface 116, the axis of which is parallel to the first direction. The testing equipment 1000 applies a sliding force to the button through the convex arc surface 116 of the sliding test piece 113. This reduces the friction between the sliding test piece 113 and the button, allowing the sliding test piece 113 to slide smoothly along the button and increasing the stability of the test.

[0194] In one specific embodiment, the above method can detect whether the second button 70 is qualified when subjected to a uniform sliding force with a fixed value. That is, step S23 specifically includes: moving the third support frame 500 at a uniform speed along a third direction, causing the first sensor 700 and the sliding test piece 113 to move at a uniform speed along a third direction, so that the pressing force applied by the sliding test piece 113 to the second button 70 becomes a uniform sliding force. At this time, the generated time-sliding force curve is as follows... Figure 27 As shown.

[0195] Specifically, the third driving component 620 is activated, causing it to move the first sensor 700 and the first test assembly 110 downwards, thus applying pressure to the second button 70 via the sliding test component 113, which gradually increases. Then, the third driving component 620 is controlled to stop operating for a certain period, ensuring that the pressure applied by the sliding test component 113 to the second button 70 remains constant. Next, the second driving component 610 is controlled to start operating, causing it to move the sliding test component 113 at a constant speed along the Y-axis, thus applying a fixed sliding force to the second button 70.

[0196] During the process of applying a fixed sliding force to the second button 70 using the sliding test piece 113, the sliding force is fed back to the first sensor 700, and the controller can read the sliding force detected by the first sensor 700. The controller generates a time-sliding force curve based on the changes in sliding force and time. The time-sliding force curve shows whether the response of the second button 70 is continuous. If the sliding force remains constant in the time-sliding force curve, the response of the second button 70 is continuous. Conversely, if the sliding force suddenly decreases or increases in the time-sliding force curve, the response of the second button 70 is discontinuous, indicating that the second button 70 is unqualified.

[0197] In another specific embodiment, it can be detected whether the second button 70 is qualified when subjected to a sliding force with varying force and a constant speed. That is, step S22 specifically includes: while the first sensor 700 and the sliding test piece 113 move at a constant speed in a third direction, the first sensor 700 and the sliding test piece 113 gradually move downward, or the first sensor 700 and the sliding test piece 113 gradually move upward, so that the sliding force gradually increases or gradually decreases. This makes the pressing force applied by the sliding test piece 113 to the second button 70 a sliding force that is constant and gradually increases or gradually decreases. At this time, the generated time-sliding force curve is as follows. Figure 26 As shown.

[0198] Specifically, the second driving component 610 is activated, causing it to move the sliding test component 113 at a constant speed along the Y-axis. Simultaneously, the third driving component 620 is activated, causing it to move the first sensor 700 and the first test component 110 downwards, applying a gradually increasing sliding force to the second button 70 via the sliding test component 113. Next, the third driving component 620 is activated to move the first sensor 700 and the first test component 110 upwards, causing the sliding test component 113 to apply a gradually decreasing sliding force to the second button 70. The subsequent method for determining whether the second button 70 is qualified is similar to the above and will not be repeated.

[0199] In another specific embodiment, the above method can detect whether the second button 70 is qualified when subjected to a sliding force with a fixed force value and acceleration. That is, step S22 specifically includes: moving the second support frame 400 along a third direction with a certain acceleration, causing the first sensor 700 and the sliding test piece 113 to move along a third direction with a certain acceleration, so that the pressing force applied by the sliding test piece 113 to the second button 70 becomes a sliding force with acceleration. At this time, the generated time-sliding force curve is as follows. Figure 27 As shown.

[0200] Specifically, the third driving component 620 is activated, causing it to move the first sensor 700 and the first test assembly 110 downwards, thus applying pressure to the second button 70 via the sliding test component 113, which gradually increases. Then, the third driving component 620 is controlled to stop operating for a certain period, maintaining a constant pressure on the second button 70 from the sliding test component 113. Next, the second driving component 610 is activated, causing it to slide the sliding test component 113 along the Y-axis with a certain acceleration, thus applying a sliding force with a certain acceleration to the second button 70.

[0201] The method for determining whether the second button 70 is qualified is the same as described above, and will not be repeated here.

[0202] As can be seen, the testing method provided in this embodiment can detect the feedback of the sliding force of the second button 70 under different conditions, which can increase the accuracy of the detection and help improve the pass rate of the second button 70.

[0203] refer to Figure 28 and Figure 29 , Figure 28 This is a flowchart illustrating the testing method provided in this application for testing the magnetic attraction force of the first button on an electronic device. Figure 29This is a state diagram of the testing equipment when testing the magnetic attraction force of the first button. The following describes the process of using testing equipment 1000 to detect the width of the gap between the electromagnet 63 and the second armature 69 of the first button 60. It can be understood that when it is necessary to detect the width of the gap between the electromagnet 63 and the second armature 69, the second test component 120 is mounted on the bottom of the first sensor 700.

[0204] Step S30: Fix the first part 61 of the first button 60 to the test fixture 122 of the second test assembly 120. That is, fix the assembly of the first armature 64, the flexible circuit board 65, and the electromagnet 63 to the test fixture 122. Specifically, clamp the first part 61 between the first test plate 123 and the second test plate 124, and then use the test fixing member 125 to fix the first test plate 123 and the second test plate 124 together.

[0205] It is understood that when the test fixture 122 only includes the first test plate 123, the first part 61 can be glued and fixed to the bottom of the first test plate 123.

[0206] Step S31: Fix the second part 62 of the first button 60 to the support column 204. That is, fix the second armature 69 to the support column 204. Specifically, the second armature 69 can be directly fixed to the top of the support column 204, or a pad can be set on the top surface of the base 201, and then the second armature 69 can be fixed to the top of the pad. The order of steps S31 and S30 can be interchanged.

[0207] Step S32: Move the second support frame 400 along the second direction, and / or move the third support frame 500 along the third direction so that the first part 61 and the second part 62 are opposite each other along the second direction.

[0208] That is, the first driving member 600 moves the first sensor 700 and the test fixture 122 downwards, the second driving member 610 moves the first sensor 700 and the first part 61 of the first button 60 along the Y-axis, and the test fixture 122 moves the first part 61 of the first button 60 downwards to approach the second part 62, so that the first part 61 and the second part 62 are opposite each other along the Z-axis. It can be understood that the activation order of the first driving member 600 and the second driving member 610 is not restricted. Specifically, turning the knob 602 causes the rotating rod 601 to rotate, causing the drive slider 603 to move downwards, thereby causing the second support frame 400, the third support frame 500, the second test assembly 120, and the first part 61 of the first button 60 to move downwards synchronously. Activating the second driving member 610 causes its driving end to move the third support frame 500, the second test assembly 120, and the first part 61 of the first button 60 synchronously along the Y-axis. It is understandable that if the first driving element 600 moves the first part 61 of the first button 60 downward, and the first part 61 and the second part 62 are already opposite each other along the Z-axis, then the second driving element 610 does not need to be activated. If the second driving element 610 moves the first part 61 downward, and the first part 61 and the second part 62 are already opposite each other along the Z-axis, then the first driving element 600 does not need to be activated.

[0209] Step S33: Move the first sensor 700 and the test fixture 122 along the second direction, so that the test fixture 122 drives the first part 61 to move along the second direction, so that there is a target gap between the electromagnet 63 and the second armature 69.

[0210] Step S33 specifically includes the following steps.

[0211] Step S331: Move the first sensor 700 and the test fixture 122 downwards, causing the test fixture 122 to move the first part 61 closer to the second part 62, so that the electromagnet 63 and the second armature 69 come into contact with each other. Specifically, activate the third drive unit 620, causing the third drive unit 620 to move the first sensor 700 and the test fixture 122 downwards. After the electromagnet 63 and the second armature 69 come into contact with each other, the third drive unit 620 stops working.

[0212] Step S332: Obtain the first distance between the extension 126 and the second sensor 800 when the electromagnet 63 and the second armature 69 are in contact. It can be understood that the reading of the first sensor 700 should be greater than 0N at this time.

[0213] Step S333: Move the first sensor 700 and the test fixture 122 upwards, causing the test fixture 122 to move the first part 61 away from the first part 61, so that a gap appears between the electromagnet 63 and the second armature 69. Specifically, activate the third drive unit 620, causing the third drive unit 620 to move the first sensor 700 and the test fixture 122 upwards.

[0214] Step S334: When a gap occurs between the electromagnet 63 and the second armature 69, the second distance between the extension 126 detected by the second sensor 800 and the second sensor 800 is obtained.

[0215] Step S335: When the difference between the first distance and the second distance is the target gap between the electromagnet 63 and the second armature 69, the first sensor 700 and the test fixture 122 are stopped moving to maintain the target gap between the electromagnet 63 and the second armature 69. Specifically, after the gap between the electromagnet 63 and the second armature 69 reaches the target gap, the third drive unit 620 is controlled to stop working.

[0216] Step S34: After energizing the electromagnet 63 through the flexible circuit board 65 and the first armature 64, the magnetic attraction force between the electromagnet 63 and the second armature 69 is obtained. Specifically, the flexible circuit board 65 is energized, and the electricity from the flexible circuit board 65 is transmitted to the electromagnet 63 through the first armature 64, energizing the electromagnet 63. After the electromagnet 63 is energized, a magnetic attraction force is generated between the electromagnet 63 and the second armature 69. The magnetic attraction force causes the electromagnet 63 to move downward, causing the first part 61 of the first button 60 and the test fixture 122 to move downward synchronously. At this time, the reading of the first sensor 700 is the magnitude of the magnetic attraction force between the electromagnet 63 and the second armature 69. It can be understood that after the electromagnet 63 is energized, since the first sensor 700 has an elastic element, the magnetic attraction force will cause the elastic element to deform, thereby allowing the first sensor 700 to measure the magnitude of the force. Furthermore, after the flexible circuit board 65 is de-energized, the magnetic attraction between the electromagnet 63 and the second armature 69 disappears, and the first part of the first button 60 will move upward and reset.

[0217] Step S35: Determine whether the first button 60 is qualified based on the magnetic attraction force. Specifically, after detecting the magnetic attraction force between the electromagnet 63 and the second armature 69, compare the detected magnetic attraction force with the standard value. If the error between the two is large, it proves that the first button 60 is unqualified. If the error between the two is small, it proves that the first button 60 is qualified.

[0218] It is understood that before the second sensor 800 detects the first distance, the fourth drive unit 630 can be activated, so that the fourth drive unit 630 drives the second sensor 800 to move along the Z-axis direction, so that the movement of the second sensor 800 can detect the position of the extension 126.

[0219] It is understood that steps S32 to S35 above can be executed automatically by the controller. In other embodiments, steps S32 to S34 are executed automatically by the controller, while step S35 can be determined manually.

[0220] The above testing method can detect the magnetic attraction force of the first button 60, thereby determining whether the first button 60 is qualified, which facilitates R&D personnel in judging the pass rate of the first button 60. By setting the second sensor 800 and the extension 126, a target gap can be maintained between the electromagnet 63 and the second armature 69. The target gap is the gap that actually needs to be maintained when the first button 60 is applied to the electronic device 2000. This increases the accuracy of the test of the magnetic attraction force between the electromagnet 63 and the second armature 69. The testing device 1000 is slidably connected to the first support frame 300 via the second support frame 400, enabling the second support frame 400 to slide relative to the first support frame 300 in the second direction. It is also slidably connected to the second support frame 400 via the third support frame 500, enabling the third support frame 500 to slide relative to the second support frame 400 in the third direction. This allows the test fixture 122 to move quickly to the corresponding position, thereby enabling the relative position of the first part 61 and the second part 62 of the button to quickly reach the expected state, increasing the testing efficiency.

[0221] In summary, this application provides a testing device 1000 and a testing method that can test the feedback of buttons under pressing and sliding forces, as well as the magnetic attraction force of buttons, making it highly applicable.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
