[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The button lifespan testing device for electronic devices disclosed in this invention is mainly applied to scenarios where existing button lifespan testing devices mostly adopt a single pressing mode with fixed force and frequency, which fails to simulate different pressing angles, contact points and habit differences in actual use, resulting in test conditions being out of touch with real scenarios and reducing the accuracy of button durability and product reliability assessment.

[0020] Reference Figures 1-6A device for testing the lifespan of buttons on electronic devices includes a testing platform 2. An adaptive clamping assembly 4 is provided on the upper side of the testing platform 2. Multiple lifting cylinders 1 are arranged at equal intervals on the upper side of the testing platform 2. The extension and retraction ends of the multiple lifting cylinders 1 are provided with the same adaptive adjustment and testing assembly 3. The adaptive adjustment and testing assembly 3 includes a rotating block 311. A sliding groove cylinder 310 is fixedly connected to the lower side of the rotating block 311. Multiple fixing blocks 321 are fixedly connected at equal intervals on the outer wall of the sliding groove cylinder 310. A crescent-shaped plate 308 is fixedly connected to one side of two fixing blocks 321 located on the same vertical line. A rotating rod 327 is connected to the opposite side of the two crescent-shaped plates 308 through a bearing. A toggle plate 328 is fixedly connected to the outer wall of the rotating rod 327. Screws 326 are fixedly connected to both sides of the toggle plate 328. The two screws 326 toggle the same side of the plate 328. The two screws 326 are symmetrically arranged. Multiple counterweight nuts 325 are screwed onto the outer wall of the two screws 326 respectively.

[0021] In this invention, a rotary motor 329 is fixedly connected to the outer wall of one of the crescent-shaped plates 308. The drive end of the rotary motor 329 is connected to one end of the rotating rod 327 via a coupling. A limiting sliding plate 324 is slidably connected inside the groove cylinder 310. A counting sensor plate 323 is provided at one end of the limiting sliding plate 324 located outside the groove cylinder 310. The counting sensor plate 323 is in contact with the actuating plate 328.

[0022] In this invention, one end of a reset spring 320 is fixedly connected to the upper side of the limiting sliding plate 324, the other end of the reset spring 320 is fixedly connected to the lower side of the rotating block 311, and a striking pin 309 is fixedly connected to the lower side of the limiting sliding plate 324.

[0023] In this invention, a miniature pressure sensor 331 is disposed inside the striking pin 309, and a rebound detection pin 322 is slidably connected inside the striking pin 309. One end of the rebound detection pin 322 passes through the striking pin 309 and is located on its outer wall, while the other end of the rebound detection pin 322 is located directly above the force-bearing end of the miniature pressure sensor 331. One end of a telescopic spring 330 is fixedly connected to the side of the rebound detection pin 322 near the miniature pressure sensor 331, and the other end of the telescopic spring 330 is fixedly connected to the inner wall of the striking pin 309.

[0024] In this invention, the telescopic ends of multiple lifting cylinders 1 are provided with the same square frame 301. Two X-axis rails 302 are respectively arranged opposite each other on the upper side of the square frame 301, and two Y-axis rails 307 are respectively arranged opposite each other on the upper side of the square frame 301. Sliding blocks 303 are slidably connected to the two X-axis rails 302 and the two Y-axis rails 307. Multiple sliding blocks 303 can be fixedly connected to the square frame 301 by bolts. Two X-axis moving rods 305 are fixedly connected at equal intervals on the opposite side of the two sliding blocks 303 on the X-axis rails 302. Two Y-axis moving rods 304 are fixedly connected at equal intervals on the opposite side of the two sliding blocks 303 on the Y-axis rails 307. The two Y-axis moving rods 304 are located directly below the two X-axis moving rods 305. The outer walls of the two Y-axis moving rods 304 and the two X-axis moving rods 305 are slidably connected to the same adjusting block 306.

[0025] In this invention, a cross-shaped connecting frame 332 is fixedly connected to the lower side of the adjusting block 306, and a perforated sliding ring 312 is fixedly connected to the lower side of the cross-shaped connecting frame 332. An adjusting rotating ring 319 is provided inside the perforated sliding ring 312. The adjusting rotating ring 319 can be fixed to the perforated sliding ring 312 by bolts. A locking rod 315 is fixedly connected inside the adjusting rotating ring 319. A rotating block 311 is connected to the outer wall of the locking rod 315 by a bearing. Two ratchet sleeves 314 are fixedly connected to both sides of the rotating block 311. The two ratchet sleeves 314 are respectively sleeved on the outer wall of the locking rod 315. The two ends of the locking rod 315 are slidably connected to toothed sleeves 316. The toothed grooves inside the two toothed sleeves 316 respectively mesh with the outer wall of the corresponding ratchet sleeve 314.

[0026] In this invention, locking springs 318 are respectively fitted on the outer walls of both ends of the locking rod 315. One end of the two locking springs 318 is fixedly connected to one side of the corresponding toothed sleeve 316, and the other end of the two locking springs 318 is fixedly connected to the inner wall of the adjusting ring 319. Two rotating buckles 317 are connected to the upper side of the adjusting ring 319 through bearings. One end of the two rotating buckles 317 is respectively engaged with the outer wall of the corresponding toothed sleeve 316.

[0027] Specifically, the horizontal position of the adjusting block 306 is adjusted according to the button position to be detected by the electronic device until the striking pin 309 is directly above the button to be detected. Since the rotating block 311 is connected to the locking rod 315 through a bearing, and the adjusting ring 319 slides inside the perforated sliding ring 312, the angle at which the striking pin 309 presses the button to be detected can be adjusted by rotating the rotating block 311 and rotating it around the locking rod 315. The rotating rod 327 is driven by the rotating motor 329 to rotate the toggle plate 328. While the toggle plate 328 is rotating, it intermittently presses against the counting sensor plate 323. Thus, the time limit sliding plate 324 overcomes the action of the return spring 320 and drives the striking pin 309 to descend and press the button to be detected. Whenever the toggle plate 328 releases the counting sensor plate 323, the counting sensor plate 32... 3. Counting is performed using the remote control terminal. Whenever the touch pin 309 is pressed, the rebound detection pin 322 is first squeezed and overcomes the action of the telescopic spring 330 to contact the miniature pressure sensor 331. When the button can rebound normally, the rebound detection pin 322 remains in contact with the button even when the touch pin 309 moves away from the button. At this time, the pressure on the miniature pressure sensor 331 is always within the threshold. When the button cannot rebound normally, the rebound detection pin 322 moves away from the miniature pressure sensor 331 under the action of the telescopic spring 330, so that the pressure it receives is far below the threshold. At the same time, the alarm 313 is triggered to notify the staff to check whether the button is damaged. If it is damaged, the lifespan range of the button of the electronic device can be determined by combining the number of touches recorded by the counting sensor 323 with factors such as touch force and touch angle.

[0028] In specific application scenarios, multiple sliding blocks 303 slide on corresponding X-axis tracks 302 or Y-axis tracks 307, thereby causing the adjusting block 306 to drive the stylus 309 to quickly and adaptively adjust according to the position of the button to be detected. This adapts to the detection of different electronic devices while improving work efficiency. Since the adjusting block 306 slides on two sets of interlaced X-axis moving rods 305 and Y-axis moving rods 304, stability is improved while preventing vibrations during subsequent detection from causing errors in the stylus 309. The angle at which the stylus 309 presses the button to be detected is adjusted by rotating the rotating block 311 and rotating it around the locking rod 315, thereby expanding the detection range and improving the comprehensiveness of the detection. This can be achieved through two toothed sleeves. 316 meshes with the corresponding ratchet sleeve 314, and the two ratchet sleeves 314 are fixedly connected to the rotating block 311. This allows the rotating block 311 to be adjusted to the required angle, and then the ratchet sleeve 316 engages with the ratchet sleeve 314 under the compression of the corresponding locking spring 318. This ensures that the rotating block 311 is fixed at any angle, guaranteeing the stability of the detection work. By adding a counterweight nut 325 to the toggle plate 328, the force of the striking pin 309 pressing the button can be increased, thereby simulating button life detection under different forces and further improving the comprehensiveness of the detection. By using the spring detection pin 322 in combination with the miniature pressure sensor 331, the button damage can be quickly detected and the operation can be terminated, thus ensuring the accuracy of the detection data.

[0029] Reference Figure 1 , Figure 7 and Figure 8 In a preferred embodiment, the adaptive clamping assembly 4 includes a fixing plate 401. Multiple fixing plates 401 are fixedly connected to the upper side of the testing table 2 at equal intervals. The opposite sides of two fixing plates 401 located on the same side are connected to the same bidirectional lead screw 402 via bearings. The outer wall of one end of the two bidirectional lead screws 402 located on the same side is provided with the same transmission belt 403. A clamping motor 405 is fixedly connected to one side of one of the fixing plates 401. The drive end of the clamping motor 405 is connected to one end of the corresponding bidirectional lead screw 402 via a coupling. The outer walls of the two bidirectional lead screws 402 are respectively provided with two L-shaped sliding plates 404 opposite to each other. The opposite sides of the two L-shaped sliding plates 404 located on the same side are fixedly connected to the same U-shaped connecting plate 406.

[0030] In this invention, a plurality of sliding grooves are equally spaced inside the U-shaped connecting plate 406. Clamping blocks 409 are slidably connected inside the plurality of sliding grooves. One end of each clamping block 409 is fixedly connected to a limiting rod 408. One end of each limiting rod 408 passes through the U-shaped connecting plate 406 and is located outside it. A clamping spring 407 is sleeved on the outer wall of the end of each limiting rod 408 located outside the U-shaped connecting plate 406. One end of each clamping spring 407 is fixedly connected to the outer wall of the U-shaped connecting plate 406, and the other end is fixedly connected to the inner wall of the corresponding limiting rod 408.

[0031] Specifically, the clamping motor 405, in conjunction with the transmission belt 403, causes the two bidirectional lead screws 402 to rotate simultaneously, thereby causing multiple sets of clamping blocks 409 to move relative to each other and thus clamp and fix the electronic equipment.

[0032] In specific application scenarios, since multiple clamping blocks 409 slide independently, the clamping degree is increased while adapting to the shape of different electronic devices, thus improving work efficiency.

[0033] A method for using a button lifespan testing device for an electronic device, comprising the following steps: Step 1: In use, first place the electronic device to be tested on the testing table 2, and then use the adaptive clamping assembly 4 to adaptively clamp and fix it (in this process, the clamping motor 405, in combination with the transmission belt 403, causes the two bidirectional lead screws 402 to rotate simultaneously, thereby causing multiple sets of clamping blocks 409 to move relative to each other and thus clamp and fix the electronic device. Since multiple clamping blocks 409 slide independently, the clamping degree is increased and it can adapt to the shape of different electronic devices, improving work efficiency). Step 2: Adjust the horizontal position of the adjusting block 306 according to the button position to be detected by the electronic device until the striking pin 309 is directly above the button to be detected. (During this process, multiple sliding blocks 303 slide on the corresponding X-axis track 302 or Y-axis track 307, thereby allowing the adjusting block 306 to drive the striking pin 309 to quickly and adaptively adjust according to the button position to be detected, thus adapting to the detection of different electronic devices while improving work efficiency. Since the adjusting block 306 slides on two sets of interlaced X-axis moving rods 305 and Y-axis moving rods 304, stability is improved while avoiding the situation where vibrations generated during subsequent detection cause the striking pin 309 to malfunction.) Then, according to the pressing interval of the button to be detected, the striking pin 309 is adjusted to a suitable position by multiple lifting cylinders 1. The striking pin 309 can be adjusted by rotating block 311. The angle of the rotating block 309 can be adjusted to change different pressing angles, thereby improving the comprehensiveness of the detection. (During this process, since the rotating block 311 is connected to the locking rod 315 through a bearing, and the adjusting ring 319 slides inside the perforated groove ring 312, the angle of the striking pin 309 pressing the required detection button can be adjusted by rotating the rotating block 311 and rotating it around the locking rod 315, thereby expanding the detection range and improving the comprehensiveness of the detection. Two toothed sleeves 316 and corresponding ratchet sleeves 314 can mesh with each other, and the two ratchet sleeves 314 are fixedly connected to the rotating block 311. This allows the rotating block 311 to be fixed at any angle after it is adjusted to the required angle, by the toothed sleeves 316 meshing with the ratchet sleeves 314 under the compression of the corresponding locking springs 318, thus ensuring the stability of the detection work.) Step 3: The button to be tested is pressed at a high frequency and stably by the striking pin 309, so that the button is continuously pressed and rebounded in a cycle to test the button's lifespan. (During this process, the rotating rod 327 driven by the rotating motor 329 drives the toggle plate 328 to rotate. While the toggle plate 328 rotates, it intermittently presses against the counting sensor plate 323, so that the time limit sliding plate 324 overcomes the action of the return spring 320 and drives the striking pin 309 to descend and press the button to be tested. Whenever the toggle plate 328 releases the counting sensor plate 323, the counting sensor plate 323 counts in conjunction with the remote control terminal. The force of the striking pin 309 pressing the button can be increased by adding a counterweight nut 325 to the toggle plate 328, so that the button life test can be simulated under different forces, further improving the comprehensiveness of the test.) When the button fails, it can be detected by the rebound detection pin 322 and the alarm 313 will sound. At the same time, the test will end and the operation will be completed. Personnel inspection (Whenever the trigger pin 309 is pressed, the rebound detection pin 322 is first squeezed and overcomes the action of the telescopic spring 330 to contact the miniature pressure sensor 331. When the button can rebound normally, the rebound detection pin 322 is always in contact with the button when the trigger pin 309 moves away from the button. At this time, the pressure on the miniature pressure sensor 331 is always within the threshold. When the button cannot rebound normally, the rebound detection pin 322 moves away from the miniature pressure sensor 331 under the action of the telescopic spring 330, so that the pressure it receives is much lower than the threshold. At the same time, the alarm 313 is triggered to notify the staff to check whether the button is damaged. If it is damaged, the lifespan range of the button of the electronic device can be determined by the number of touches recorded by the counting sensor plate 323, combined with factors such as touch force and touch angle. By using the rebound detection pin 322 in combination with the miniature pressure sensor 331, the damage of the button can be quickly detected and the operation can be stopped at the same time, thereby ensuring the accuracy of the detection data).
