Description
Technical Field
[0001] The invention relates to the technical field of equipment testing devices, in particular to a computer keyboard key service life testing device. Background Art
[0002] To ensure keyboards maintain stable performance over long periods of use, key life testing has become an essential step in the production process. Keyboard key life testing equipment simulates manual pressing, subjecting keys to high-frequency, long-term cycle pressure tests. This evaluates the durability, resilience, and structural stability of keys, providing crucial data support for product quality control.
[0003] During actual testing, existing testing devices have poor adaptability to changes in keyboard height and are unable to meet the testing requirements of diverse keyboard products.
[0004] With the diversification of electronic devices, keyboard designs vary significantly across brands and models, particularly in overall height. For example, mechanical keyboards are typically taller than membrane keyboards due to their internal shaft structure. Ultra-thin notebook keyboards, on the other hand, are often much shorter than traditional external keyboards for portability. Furthermore, even within the same keyboard type, key heights can vary slightly between different production batches or within different functional areas.
[0005] This inconsistency in keyboard height has brought great inconvenience to the use of existing test devices. On the one hand, the height of the press actuator of existing test devices is usually fixed or has a limited adjustment range. When faced with keyboards with large height differences, it is difficult to achieve precise alignment between the press head and the key surface. If the press head height is too high, it may lead to insufficient initial contact pressure on the key, and it will not be possible to truly simulate the actual pressing state; if the press head height is too low, it may cause excessive squeezing of the key in the initial stage of the test, which will not only affect the accuracy of the test data, but may also directly damage the keyboard under test.
[0006] Secondly, most test fixtures are designed for specific keyboard models. The fixture may not be able to effectively clamp keyboards of different sizes, causing the keyboard to shift or loosen during testing, seriously affecting the accuracy of the test results.
[0007] Therefore, the present invention provides a computer keyboard key service life testing device to solve the above problems. Summary of the Invention

[0029] In the initial state, the detection shaft 13 is at the same height under the action of the detection spring 8 and the return spring 11; When in use, the keyboard to be tested is placed inside the keyboard fixing slot 2, and the shaft control plate 10 is pushed downward to compress the return spring 11. At this time, the detection shaft 13 moves downward under the action of gravity until the detection shaft 13 contacts the keys of the keyboard.

[0030] A control structure for controlling the axis control plate 10 to slide toward the bottom of the adjustment control box 7 is provided inside the adjustment control box 7; The control structure includes triangular guide blocks 20 fixedly connected to both sides of the shaft control plate 10. Both ends of the adjustment control box 7 are slidably connected to a control shaft 21. The control shaft 21 is fixedly connected to a matching push block 22 that matches the triangular guide block 20. The matching push block 22 is set to a triangle.

[0031] When the control screw shaft 24 is in use, the control screw shaft 24 drives the control slider 25 to move in the direction of approaching or away from the adjustment control box body 7. When the control screw shaft 24 drives the control slider 25 to move in the direction of approaching the adjustment control box body 7, the driving connecting rod 28 drives the driving rod 26 to move in the direction of approaching the driving shaft 23. At this time, the inclined surface of the driving block 27 is in contact with the side surface of the driving shaft 23. Then the driving block 27 pushes the driving shaft 23 to move in the direction away from the adjustment control box body 7. At this time, the driving shaft 23 drives the control shaft 21 to move synchronously. In the initial state, the inclined surface of the cooperating pushing block 22 and the triangular guide block 20 are in contact, and the control shaft 21 synchronously drives the cooperating pushing block 22 to move. When the cooperating pushing block 22 moves, the inclined surface of the cooperating pushing block 22 pushes the triangular guide block 20 to move downward, thereby realizing the operation of pushing the shaft control plate 10 to slide downward, compressing the return spring 11, and fixing it in the current position through the control screw shaft 24.
[0032] At this time, the detection shaft 13 moves downward under the action of gravity until the detection shaft 13 contacts the keys of the keyboard, and then continues to push the shaft control board 10 downward until all the detection shafts 13 contact all the keys, and the conical pressing member 15 is inserted into the pressing cylinder 17, so that the conical pressing member 15 is pressed in the direction close to the detection shaft 13 by the pressing cylinder 17, so that the conical pressing member 15 presses the detection shaft 13, and at this time the adjustment control box 7 is pressed downward, and the adjustment control box 7 drives the shaft control board 10 and the detection shaft 13 to move downward synchronously, thereby realizing the operation of pressing the keyboard keys; After the conical pressing member 15 is inserted into the pressing cylinder 17 , the fixing protrusion 19 is snapped into the annular groove 18 , thereby further fixing the detection shaft body 13 at the current position.
[0033] After use, the control threaded shaft 24 is rotated in the opposite direction, so that the control threaded shaft 24 drives the control slider 25 to move away from the adjustment control box 7, and drives the drive rod 26 to move away from the drive shaft 23 through the drive connecting rod 28. At this time, under the action of the reset spring 11, the shaft control plate 10 and the triangular guide block 20 are pushed upward, and under the action of the inclined surface of the triangular guide block 20 and the inclined surface of the matching push block 22, the matching push block 22 is pushed to reset.
[0034] The linear drive device is used to push the adjustment control box 7 to slide toward the bottom of the detection control box 5, thereby detecting the service life of the keyboard keys.
[0035] The linear drive device can use a telescopic cylinder to push the adjustment control box 7 to slide toward the bottom of the detection control box 5.

[0039] When in use, the height of the connecting shaft 35 is adjusted by rotating the height adjustment bolt 36. At the same time, the connecting shaft 35 drives the downward push disc 31 to move synchronously. In this way, the height of the downward push shaft 32 is controlled by adjusting the height of the downward push shaft 32. The downward push height of the downward push semicircular ball 30 is controlled by adjusting the height of the downward push shaft 32, so that it can adapt to the key heights of different types of keyboards. The driving motor 33 is started to drive the adjusting and controlling sleeve 34 to rotate through the belt, and the adjusting and controlling sleeve 34 drives the connecting shaft 35 to move synchronously, and the connecting shaft 35 synchronously drives the pressing and pushing disc 31 to rotate.

When one end of the fixing rod 47 is in contact with the side of the keyboard, the clamping plate 40 continues to be pushed to slide. At this time, the driving slot 44 is fixed in the current position, and the clamping plate 40 stretches the adjustment spring 45. After use, the detection movable plate 3 is rotated to the vertical direction. At this time, the clamping plate 40 and the driving slot 44 return to their initial positions. This setting is convenient for fixing the keyboard, and can also quickly adjust the keyboard position for easy detection.

A self-locking spring 52 is installed between the self-locking plate 50 and the detection movable plate 3. In the initial state, the self-locking plate 50 is pushed to move toward the center of the detection movable plate 3 under the action of the self-locking spring 52.
[0046] When in use, when the movable end of the detection movable plate 3 is pushed to contact the support plate 38, the self-locking shaft 51 first contacts the inclined groove, and is guided by the inclined groove to push the self-locking shaft 51 to move in the direction away from the center of the detection movable plate 3, compressing the self-locking spring 52 until the self-locking shaft 51 enters the horizontal groove. Under the action of the self-locking spring 52, the self-locking plate 50 is pushed to move in the direction close to the center of the detection movable plate 3, and at the same time, the self-locking shaft 51 is pushed to slide inside the horizontal groove. When the self-locking plate 50 returns to the initial position, the self-locking shaft 51 is restricted to the current position through the horizontal groove, thereby fixing the detection movable plate 3 to improve its stability, which can effectively improve the detection effect.
[0047] After use, the self-locking plate 50 is pulled away from the center of the detection movable plate 3 to push the self-locking shaft 51 out of the horizontal groove and into the inclined groove, so that the detection movable plate 3 can move freely.
[0048] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
