Abstract
Description
Technical Field
[0001] This invention relates to the field of equipment testing devices, specifically to a device for testing the lifespan of computer keyboard keys. Background Technology
[0002] To ensure keyboards maintain stable performance over long-term use, key life testing has become an indispensable and critical step in the production process. Keyboard key life testing devices simulate manual pressing actions, subjecting keys to high-frequency, long-term cyclic pressing tests to evaluate key durability, rebound performance, and structural stability, providing crucial data support for product quality control.
[0003] In actual testing, existing testing equipment is poorly adaptable to changes in keyboard height, making it difficult to meet the testing needs of diverse keyboard products.
[0004] With the diversification of electronic device forms, keyboards from different brands and models exhibit significant design differences, particularly in their overall height. For example, mechanical keyboards, due to their internal switch structure, are typically taller than membrane keyboards; while ultra-thin laptop keyboards, prioritizing portability, are often much shorter than traditional external keyboards. Furthermore, even within the same type of keyboard, slight variations in key height can occur between different production batches or in different functional areas.
[0005] This inconsistency in keyboard height poses a significant challenge to the use of existing testing equipment. Firstly, the height of the pressing mechanism in existing equipment is typically fixed or has a limited adjustment range. When faced with keyboards of significantly different heights, it is difficult to achieve precise alignment between the pressing head and the key surface. If the pressing head is too high, the initial contact pressure on the key may be insufficient, failing to accurately simulate the actual pressing state. If the pressing head is too low, it may cause excessive pressure on the key at the initial stage of testing, affecting not only the accuracy of the test data but also potentially damaging the keyboard under test.
[0006] Secondly, the fixtures in most testing devices are designed for specific keyboard models. These fixtures may not be able to effectively hold keyboards of different sizes, causing the keyboards to shift or loosen during testing, severely impacting the accuracy of the test results.
[0007] Therefore, the present invention provides a computer keyboard key lifespan testing device to solve the above problems. Summary of the Invention
[0008] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a computer keyboard key lifespan testing device, which effectively solves the problems of poor adaptability of existing testing devices to changes in keyboard height, inability to adapt to keyboards of various heights, and inconvenience in fixing different models of keyboards.

[0063] Example 1, refer to the appendix of the instruction manual. Figure 1-15 A computer keyboard key lifespan testing device, comprising:
[0064] Support base 1, with keyboard fixing slot 2 provided on support base 1, keyboard fixing slot 2 is used to place the keyboard to be tested;
[0065] The detection movable plate 3 is rotatably connected to the support base 1 at one end, and the detection movable plate 3 is provided with an installation groove 4;
[0066] The detection control box 5 is slidably connected inside the mounting groove 4. The detection movable plate 3 is provided with a position adjustment structure for adjusting the position of the detection control box 5. The adjustment structure is used to push the detection control box 5 to move on the mounting groove 4. The detection control box 5 is provided with multiple shaft limiting holes 6.
[0067] Adjustment control box 7 is slidably connected to the inside of detection control box 5. Detection spring 8 is installed between adjustment control box 7 and detection control box 5. In the initial state, under the action of detection spring 8, adjustment control box 7 is pushed to move away from detection control box 5. Multiple shaft fixing holes 9 corresponding to shaft limiting holes 6 are opened inside adjustment control box 7.
[0068] A shaft control plate 10 is slidably connected inside the adjustment control box 7. A reset spring 11 is installed between the adjustment control box 7 and the shaft control plate 10. In the initial state, the shaft control plate 10 is pushed away from the adjustment control box 7 by the reset spring 11. The shaft control plate 10 is provided with a plurality of shaft reset holes 12 corresponding to the shaft fixing holes 9.
[0069] The testing shaft 13 passes through the shaft limiting hole 6, the shaft fixing hole 9, and the shaft reset hole 12, and the upper end of the testing shaft 13 is fixedly connected to the shaft limiting plate 14 that mates with the shaft reset hole 12; in use, the testing shaft 13 is passed through the shaft reset hole 12, the shaft fixing hole 9, and the shaft limiting hole 6 in sequence, so that the shaft limiting plate 14 and the shaft reset hole 12 fit together;
[0070] A shaft limiting structure is provided on the shaft control plate 10 to fix the detection shaft 13;
[0071] The shaft limiting structure includes a tapered clamping member 15 fixedly connected to the lower end of the shaft reset hole 12, and a clamping shrinkage groove 16 is provided in the middle of the tapered clamping member 15;
[0072] A clamping cylinder 17 is fixedly connected to one end of the shaft fixing hole 9 near the tapered clamping part 15;
[0073] The conical clamping member 15 is used to be inserted into the clamping cylinder 17, thereby squeezing the conical clamping member 15 to fix the detection shaft 13;
[0074] The detection shaft 13 has multiple annular grooves 18, and the tapered clamping member 15 has a fixed protrusion 19 that matches the annular grooves 18.
[0075] In the initial state, the detection shaft 13 is positioned at the same height under the action of the detection spring 8 and the return spring 11;
[0076] In use, the keyboard to be tested is placed inside the keyboard fixing slot 2, and the switch control plate 10 is pushed down to compress the return spring 11. At this time, the detection switch 13 moves down under the action of gravity until the detection switch 13 contacts the key of the keyboard. Then, the switch control plate 10 is pushed down until all the detection switches 13 and all the keys are in contact. Then, the conical clamping member 15 is inserted into the clamping cylinder 17, so that the clamping cylinder 17 presses the conical clamping member 15 towards the detection switch 13, so that the conical clamping member 15 presses the detection switch 13.
[0077] After the conical clamping member 15 is inserted into the clamping cylinder 17, the fixing protrusion 19 is engaged into the annular groove 18, thereby further fixing the detection shaft 13 in the current position.
[0078] The control box 7 is equipped with a control structure for controlling the shaft control plate 10 to slide closer to the bottom of the control box 7.
[0079] The control structure includes triangular guide blocks 20 fixedly connected to both sides of the shaft control plate 10, and control shafts 21 slidably connected to both ends of the adjustment control box 7. A cooperating push block 22 that cooperates with the triangular guide blocks 20 is fixedly connected to the control shaft 21. The cooperating push block 22 is set as a triangle, and a drive shaft 23 is fixedly connected to one end of the control shaft 21.
[0080] A control threaded shaft 24 is rotatably connected to one side of the control box 7, and a control slider 25 is slidably connected to the control control box 7 and threadedly connected to the control threaded shaft 24.
[0081] Both sides of the control box 7 are slidably connected to drive rods 26. One end of the drive rod 26 is fixedly connected to a drive block 27 for cooperating with the drive shaft 23. The cross section of the drive block 27 is triangular. The other end of the drive rod 26 is connected to the control slider 25 by a drive connecting rod 28.
[0082] In use, rotating the control threaded shaft 24 causes the control slider 25 to move closer to or further away from the adjustment control housing 7. When the control slider 25 moves closer to the adjustment control housing 7 via the control threaded shaft 24, the drive rod 26 moves closer to the drive shaft 23 via the drive linkage 28. At this time, the inclined surface of the drive block 27 is in contact with the side of the drive shaft 23. Subsequently, the drive block 27 pushes the drive shaft 23 to move away from the adjustment control housing 7. At this time, the drive shaft 23 drives the control shaft 21 to move synchronously. In the initial state, the inclined surfaces of the cooperating push block 22 and the triangular guide block 20 are in contact. The control shaft 21 drives the cooperating push block 22 to move synchronously. When the cooperating push block 22 moves, the inclined surface of the cooperating push block 22 pushes the triangular guide block 20 downward, thereby realizing the operation of sliding the control plate 10 of the push shaft downward and compressing the return spring 11, and fixing it in the current position via the control threaded shaft 24.
[0083] At this time, the detection switch 13 moves downward under the action of gravity until it contacts the key on the keyboard. Then, the switch control plate 10 continues to be pushed downward until all the detection switches 13 and all the keys are in contact. Then, the conical clamping member 15 is inserted into the clamping cylinder 17, so that the clamping cylinder 17 presses the conical clamping member 15 towards the detection switch 13, so that the conical clamping member 15 presses the detection switch 13. At this time, the adjustment control box 7 is pressed down, and the adjustment control box 7 drives the switch control plate 10 and the detection switch 13 to move downward synchronously, thereby realizing the operation of pressing the keyboard key.
[0084] After the conical clamping member 15 is inserted into the clamping cylinder 17, the fixing protrusion 19 is engaged into the annular groove 18, thereby further fixing the detection shaft 13 in the current position.
[0085] After use, rotate the control threaded shaft 24 in the reverse direction, causing the control threaded shaft 24 to drive the control slider 25 to move away from the adjustment control box 7. Through the drive linkage 28, the drive rod 26 is driven to move away from the drive shaft 23. At this time, under the action of the return spring 11, the shaft control plate 10 and the triangular guide block 20 are pushed to move upward. Under the action of the inclined surface of the triangular guide block 20 and the inclined surface of the mating push block 22, the mating push block 22 is pushed to reset.
[0086] A linear drive device is used to push the adjustment control box 7 to slide towards the bottom of the detection control box 5, thereby detecting the lifespan of the keyboard keys.
[0087] The linear drive device can use a telescopic cylinder to push the adjustment control box 7 to slide towards the bottom of the detection control box 5.
[0088] The linear drive unit may also include a mounting plate 29 that is detachably connected to the top of the adjustment control box 7, on which a plurality of pushing hemispheres 30 arranged in a circumferential array are fixedly connected;
[0089] A downward pushing disk 31 is rotatably connected to the detection control box 5, and multiple downward pushing shafts 32 that cooperate with the pushing hemisphere 30 are fixedly connected to the downward pushing disk 31;
[0090] The downward pressure pushes the disc 31 to rotate via the drive motor 33.
[0091] In use, the drive motor 33 drives the downward pushing disk 31 to rotate. When the downward pushing disk 31 rotates, the downward pushing shaft 32 and the pushing hemisphere 30 come into contact. The downward pushing shaft 32 pushes the pushing hemisphere 30 to slide downward, and the pushing hemisphere 30 simultaneously drives the mounting plate 29 to slide downward. The mounting plate 29 then drives the adjustment control box 7 to slide downward. When the pushing hemisphere 30 and the downward pushing shaft 32 disengage, the adjustment control box 7 is pushed upward to reset under the action of the detection spring 8. This reciprocating motion can improve the detection efficiency. The number of times the downward pushing disk 31 can push the adjustment control box 7 to slide downward in one revolution can be calculated based on the number of pushing hemispheres 30 and the number of downward pushing shafts 32. The accurate result can be achieved by controlling the speed of the drive motor 33. The above calculation method is existing technology and will not be elaborated here.
[0092] An adjustment control sleeve 34 is rotatably connected to the detection control housing 5. A connecting shaft 35 is fixedly connected to the upper end of the pressing and pushing disc 31. The connecting shaft 35 is slidably connected inside the adjustment control sleeve 34. A height adjustment bolt 36 is rotatably connected to the upper end of the adjustment control sleeve 34. The height adjustment bolt 36 and the connecting shaft 35 are threadedly connected. The adjustment control sleeve 34 and the drive motor 33 are connected by a belt. The drive motor 33 is fixedly connected to the detection control housing 5.
[0093] In use, the height of the connecting shaft 35 is adjusted by rotating the height adjusting bolt 36. At the same time, the connecting shaft 35 drives the pressing disk 31 to move synchronously. By adjusting the height of the pressing disk 31, the height of the pressing shaft 32 is controlled. In turn, the pressing height of the pressing hemisphere 30 is controlled by adjusting the height of the pressing shaft 32, so as to adapt to the key height of different types of keyboards.
[0094] The drive motor 33 starts and drives the adjustment control sleeve 34 to rotate via the belt. The adjustment control sleeve 34 drives the connecting shaft 35 to move synchronously, and the connecting shaft 35 drives the downward push to rotate the disc 31.
[0095] In the second embodiment, the position adjustment structure includes an adjustment threaded shaft 37 rotatably connected to the detection movable plate 3. The adjustment threaded shaft 37 is threadedly connected to the detection control box 5. The position of the detection control box 5 inside the mounting slot 4 is adjusted by rotating the adjustment threaded shaft 37, so that it can be adapted to different models of keyboards.
[0096] In embodiment 3, multiple support plates 38 are fixedly connected to both ends of the support base 1. A sliding member is slidably connected to the support plate 38 away from the swing end of the detection movable plate 3. A pulling rod 39 is connected between the detection movable plate 3 and the sliding member.
[0097] A pressure plate 40 is slidably connected inside the keyboard fixing slot 2. A pressure connecting rod 41 is connected between the pressure plate 40 and the sliding part. A keyboard fixing plate 42 is fixedly connected to the pressure plate 40. A pressure spring 43 is installed between the keyboard fixing plate 42 and the pressure plate 40. In the initial state, under the action of the pressure spring 43, the keyboard fixing plate 42 is pushed to move away from the pressure plate 40.
[0098] The keyboard fixing slot 2 is slidably connected to the drive slot 44, and the clamping plate 40 is slidably connected to the drive slot 44. An adjusting spring 45 is installed between the drive slot 44 and the clamping plate 40. In the initial state, the adjusting spring 45 pulls the clamping plate 40 to move closer to the drive slot 44.
[0099] Both sides of the drive slot 44 are fixedly connected to support rods 46. The side of the support rod 46 closest to the keyboard fixing slot 2 is rotatably connected to a direction fixing rod 47. Both sides of the keyboard fixing slot 2 are rotatably connected to one end of multiple support rods 48. The other end of the support rods 48 is rotatably connected to the direction fixing rod 47.
[0100] In use, rotate the detection movable plate 3 so that the movable end of the detection movable plate 3 contacts the support plate 38. When the detection movable plate 3 swings, the sliding member is pushed down by pulling the connecting rod 39. At this time, the sliding member drives the pressing connecting rod 41 to move the pressing plate 40 towards the keyboard fixing groove 2 until the keyboard fixing plate 42 and the side of the keyboard to be tested are in contact. Then the pressing spring 43 is compressed to fix the keyboard to be tested.
[0101] When the movable end of the detection plate 3 is pushed to contact the support plate 38, the clamping rod 41 drives the clamping plate 40 to move closer to the keyboard fixing slot 2. The clamping plate 40 simultaneously drives the drive slot 44 to move. When the drive slot 44 moves closer to the keyboard fixing slot 2, the support rod 46 drives one end of the fixing rod 47 to move synchronously. The support rod 48 supports the other end of the fixing rod 47 to move closer to the two sides of the keyboard to be tested until the keyboard to be tested is fixed in the center of the keyboard fixing slot 2. When one end of the fixing rod 47 is in contact with the side of the keyboard, the clamping plate 40 is pushed to slide. At this time, the drive slot 44 is fixed in the current position, and the clamping plate 40 stretches the adjusting spring 45. After use, the detection plate 3 is rotated to the vertical direction. At this time, the clamping plate 40 and the drive slot 44 return to the initial position. This setting facilitates the fixing of the keyboard and allows for quick adjustment of the keyboard position for easy testing.
[0102] In embodiment four, a self-locking groove 49 is provided on the support plate 38 near the swing end of the detection movable plate 3. The self-locking groove 49 includes a horizontal groove and an inclined groove that communicates with one end of the horizontal groove.
[0103] The swing end of the detection movable plate 3 is slidably connected to a self-locking plate 50. Both ends of the self-locking plate 50 are fixedly connected to self-locking shafts 51 that cooperate with self-locking grooves 49. A self-locking spring 52 is installed between the self-locking plate 50 and the detection movable plate 3. In the initial state, under the action of the self-locking spring 52, the self-locking plate 50 is pushed to move towards the center of the detection movable plate 3.
[0104] 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. Guided by the inclined groove, the self-locking shaft 51 is pushed to move away from the center of the detection movable plate 3, compressing the self-locking spring 52. After 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 closer to the center of the detection movable plate 3, while the self-locking shaft 51 slides inside the horizontal groove. When the self-locking plate 50 returns to the initial position, the horizontal groove restricts the self-locking shaft 51 to the current position, thereby fixing the detection movable plate 3 and improving its stability, which can effectively improve the detection effect.
[0105] After use, pull the self-locking plate 50 to move away from the center of the detection movable plate 3, 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.
[0106] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
