[0002] As the most commonly used input device for computers, the feel of the keyboard directly affects the user experience. Different users have different requirements for key travel due to differences in typing habits, finger strength, and operation preferences. For example, users who are used to typing quickly tend to prefer short key travel to improve input speed; while users who engage in text creation and need precise input may prefer long key travel to feel the feedback of the keys.
[0003] However, traditional keyboards have a fixed key travel distance, which cannot be adjusted to meet individual user needs. This not only reduces user comfort but may also affect input efficiency and accuracy. Furthermore, with the development of different types of keyboards such as mechanical and membrane keyboards, users have increasingly higher expectations for keyboard functionality and customization. Most existing adjustable keyboards only allow for simple key layout adjustments and lack effective solutions for adjusting key travel distance, making it difficult to meet the growing and diverse needs of users. Therefore, we propose a keyboard with finely adjustable key travel distance. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-5This utility model provides a technical solution: a keyboard with adjustable key travel, including a keyboard top cover 1, a plurality of keycaps 24 disposed on the keyboard top cover 1, a rectangular ring-shaped keyboard side cover 10 fixedly installed on the side of the keyboard top cover 1, a plurality of threaded holes 11 disposed on the left and right sides of the keyboard side cover 10, a keyboard base plate 12 disposed inside the keyboard side cover 10, a keyboard circuit board 13 fixedly installed on the upper surface of the keyboard base plate 12, and a plurality of plugs disposed on the left and right sides of the keyboard base plate 12. Hole 14, corresponding to the threaded hole 11, is internally threaded with a fastening screw 15. The end of the fastening screw 15 is fixedly installed with a plug-in support post 151. The plug-in support post 151 and the plug-in hole 14 are plugged in and engaged. By adjusting the up and down position of the keyboard base plate 12, the distance between the keyboard circuit board 13 and the keycap 24 can be further adjusted, thereby achieving the effect of fine adjustment of the key travel. The fastening screw 15 is tightened, and the plug-in support post 151 is inserted into the plug-in hole 14 to achieve the limiting and fixing operation of the keyboard base plate 12.
[0029] In this embodiment, multiple insertion holes 14 are arranged along the width direction of the keyboard base plate 12, and multiple threaded holes 11 in each group are arranged along the vertical direction, which facilitates the normal threaded connection of the fastening screws 15 and the normal insertion and engagement of the insertion support column 151.
[0030] Specifically, both the cross-section of the insertion support column 151 and the insertion hole 14 are circular. The size of the insertion support column 151 is adapted to the size of the insertion hole 14, so that the insertion support column 151 can be stably inserted into the insertion hole 14 for limiting support operation.
[0031] Furthermore, multiple circuit board contacts 131 are fixedly mounted on the upper surface of the keyboard circuit board 13. The number of circuit board contacts 131 is equal to the number of keycaps 24. Multiple key sockets 2 are fixedly mounted on the keyboard top cover 1. Key switches 23 are slidably connected inside the key sockets 2. An elastic conductive patch 22 is fixedly mounted on one inner wall of the key socket 2. The end plate of the elastic conductive patch 22 is located between the circuit board contacts 131 and the key switches 23. When the key switches 23 are pressed down by the keycaps 24, they squeeze the elastic conductive patch 22 to contact the circuit board contacts 131, triggering a key signal.
[0032] In addition, the key base 2 is provided with a sliding hole 20 arranged in the vertical direction. The key shaft 23 is located in the sliding hole 20 and is slidably connected to the sliding hole 20. The cross-section of both the key shaft 23 and the sliding hole 20 is rectangular. The size of the key shaft 23 is adapted to the size of the sliding hole 20. The rectangular design prevents the key shaft 23 from rotating during sliding, so that the key shaft 23 can only slide stably in the vertical direction, which improves the stability and accuracy of key operation and further ensures the sensitivity and accuracy of key signal triggering.
[0033] It is worth noting that support protrusions 21 are fixedly installed on all four sides of the key socket 2. The support protrusions 21 are fixedly installed on the upper surface of the keyboard cover plate 1, so that the key socket 2 is stably installed on the keyboard cover plate 1, providing a stable support structure for the sliding of the key switch 23.
[0034] It is worth noting that a cross-shaped locking block 231 is fixedly installed on the top surface of the key switch 23, and an upper arc-shaped surface 241 is provided on the upper surface of the keycap 24. An inner protruding post 25 is fixedly installed on the top wall of the keycap 24, and a cross groove 251 arranged vertically is provided in the inner protruding post 25. The cross-shaped locking block 231 and the cross groove 251 are engaged and matched, and the two engage and match to achieve a stable connection between the keycap 24 and the key switch 23. At the same time, the upper arc-shaped surface 241 on the keycap 24 conforms to the shape of the fingers, improving the user's operating comfort.
[0035] Finally, it should be noted that the keyboard circuit board 13, circuit board contacts 131, and elastic conductive patch 22 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the adapted controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.
[0036] When using the keyboard with adjustable key travel, if it is necessary to adjust the key travel, first locate the fastening screws 15 on both sides of the keyboard side cover 10. By rotating the fastening screws 15, remove the plug support post 151 from the corresponding plug hole 14. Then, adjust the position of the keyboard base plate 12 up and down to adjust the position of the keyboard circuit board 13. At this time, the distance between the circuit board contact 131 and the keycap 24 changes, thus achieving a fine adjustment of the travel. After adjustment, continue to screw the fastening screws 15 into the corresponding threaded holes 11 to ensure that the plug support post 151 continues to be inserted into the plug hole 14, thereby supporting and fixing the keyboard base plate 12.
[0037] During normal use, when a finger presses the keycap 24, the keycap 24 drives the key switch 23 to move vertically downward in the sliding hole 20 of the key base 2. During this process, the key switch 23 squeezes the elastic conductive patch 22, so that it contacts the circuit board contact 131 on the keyboard circuit board 13, triggering the key signal. The signal is transmitted to the computer through the keyboard circuit board 13.
[0038] After the keycap 24 is released, the key shaft 23 moves upward and resets along the sliding hole 20 under the elastic action of the elastic conductive patch 22 when it returns to its original shape.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
