For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] The actuation force of existing mechanical keyboard switches is fixed after production; adjusting the actuation force requires replacing the switch. Therefore, existing mechanical keyboard switches cannot satisfy users' personalized demands for tactile feedback.

[0027] To address the problems existing in the prior art, this embodiment provides a mechanical keyboard switch with adjustable pressure, referring to... Figure 1 and Figure 2 The switch includes a mounting base 1, a movable part 2, a spring 3, and an adjusting screw 4. The movable part 2 has a connecting end 21, a top abutment 22, and a spindle 23 arranged from top to bottom. The spindle 23 is cylindrical, and the top abutment 22 protrudes from the outer periphery of the top of the spindle 21. The cross-section of the connecting end 22 is cross-shaped and is used to snap into the inside of the keycap.

[0028] The shaft 23 is movably inserted into the mounting base 1, and the spring 3 is sleeved on the outer periphery of the shaft 23, with the top of the spring 3 abutting against the bottom of the top plate 22. The bottom of the mounting base 1 is provided with a threaded hole, and the adjusting screw 4 is threadedly connected to the threaded hole.

[0029] When adjusting screw 4 is turned in the forward direction, it moves inward, compressing spring 3 and increasing its elastic potential energy, thus increasing the actuation force of the switch. When adjusting screw 4 is turned in the reverse direction, spring 3 releases, decreasing its elastic potential energy and thus decreasing the actuation force of the switch. Therefore, the mechanical keyboard switch in this embodiment achieves adjustable actuation force, satisfying the personalized tactile feedback of different users.

[0030] Specifically, the mounting base 1 of this embodiment includes a shaft base 11 and a shaft cover 12. The shaft cover 12 is located above the shaft base 11. The shaft cover 12 has a first vertical hole 121 inside for the shaft 23 to move. The shaft 23 is movably inserted into the first vertical hole 121.

[0031] Combination Figure 3 As shown, the shaft base 11 has a second vertical hole 111 inside, and the bottom end of the second vertical hole 111 has an internal thread to form the aforementioned threaded hole. A guide post 113 is provided inside the second vertical hole 111. The guide post 113 is fixedly connected to the inner wall of the second vertical hole 111 through a connecting arm 112. The guide post 113 has a third vertical hole 1131 inside for the shaft 23 to pass through. The bottom end of the third vertical hole 1131 (i.e., the bottom end face of the guide post 113) is a closed end. When the movable part 2 is clicked, the bottom end of the shaft 23 can contact the bottom end of the third vertical hole 1131.

[0032] The bottom end of the spring 3 is sleeved on the outer periphery of the guide post 113. The bottom end of the spring 3 is sleeved between the hole wall of the second vertical hole 111 and the outer periphery of the guide post 113. During the extension and retraction of the spring 3, the guide post 113 can guide and limit the spring 3, and prevent the spring 3 from bending.

[0033] Furthermore, the shaft in this embodiment also includes a push rod 5, combined with... Figure 4 As shown, the push rod 5 has an annular force-receiving part 51, and a pushing part 52 extends upward from the force-receiving part 51. The force-receiving part 51 contacts the top of the adjusting screw 4. The connecting arm 112 extends from the inner wall of the second vertical hole 111 towards the center of the hole. The connecting arm 112 has clearance notches 114 on both sides to allow the pushing part 52 of the push rod 5 to pass upward. After passing upward through the clearance notches 114, the pushing part 52 contacts the bottom end of the spring 3.

[0034] In this embodiment, the shaft 23 has a middle section and a bottom end. The diameter of the middle section is smaller than the inner diameter of the spring 3, and the diameter of the bottom end is smaller than the inner diameter of the force-receiving part 51 of the push rod 5, so that the bottom end of the shaft 23 can pass downward through the push rod 5.

[0035] In this embodiment, one end of the adjusting screw 4 is a pushing end 41, and the other end is a turning end 42. The turning end 42 protrudes from the threaded hole of the mounting base 1. The outer surface of the turning end 42 has a transmission part for engaging with a turning tool. Preferably, the transmission part has a cross-shaped notch so that the adjusting screw 4 can be turned with a screwdriver.

[0036] Furthermore, the middle part of the pushing end 41 of the adjusting screw 4 is a hollow structure so that the bottom end of the guide post 113 can extend into it.

[0037] By making the push rod 5 and the adjusting screw 4 into hollow structures, the vertical dimension of the shaft can be shortened compared to using solid push rods and adjusting screws, while ensuring that the moving length of the adjusting screw 4 can be transmitted to the spring 3 through the push rod 5.

[0038] In this embodiment, the mechanical keyboard switches are mounted on the main circuit board of the mechanical keyboard via welding, hot-swapping, or other methods. When the user presses down on the keycap, the pressure is transmitted to the movable component 2. The movable component 2 pushes the spring 3 to compress, causing the movable component 2 to sink. The metal spring 6, which is connected to the movable component 2, presses down and contacts the metal contact part 7, triggering a command. After the pressure is released, the spring 3 releases, pushing the movable component 2 and the keycap upward to their original position. By turning the adjusting screw 4 at the bottom of the switch in either the forward or reverse direction, different tactile sensations can be achieved.

[0039] Another embodiment of this application provides a keyboard including the aforementioned switches.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
