Description

Technical Field

[0001] This utility model relates to the field of push button switch technology, and in particular to a push button switch with adjustable feel that is mainly used in products such as keyboards. Background Technology

[0002] Push-button switches are a common type of switch, including magnetic axis switches, inductive axis switches, and optical axis switches. Taking magnetic axis switches as an example, traditional magnetic axis switches generally include an upper shell, a lower shell, a push button, a spring, and a magnet. Pressing the push button compresses the spring, triggering a Hall effect switch on the circuit board via the magnet, thus actuating the button. Releasing the push button causes the spring to return to its original position, providing the tactile feedback when pressed. The entire switch's spring force is determined by the spring. The problem with this structure is that the tactile feedback relies entirely on the linear spring force, which is constant, resulting in a fixed rebound force for the button. This lack of damping adjustment leads to a monotonous tactile feel, only adjustable by replacing the spring, and cannot adapt to diverse operational needs. While there are push-button switches on the market that can change the button feel, such as the adjustable feel key structure and keyboard disclosed in Chinese utility model patent CN218896583U, their adjustment mechanisms are significantly more complex, costly, and cumbersome to assemble, and they are inconvenient to adjust the feel externally. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing an adjustable switch with a simpler structure, more reasonable design, fewer parts, lower cost, and more convenient operation.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an adjustable switch, comprising a handle, an upper shell, and a bottom shell, wherein the upper shell and the bottom shell are assembled and fixed, the handle is installed between the upper shell and the bottom shell and extends partly from the upper shell; the switch is triggered by pressing the handle downward; a spring is provided between the handle and the bottom shell, and the handle is driven to return to its original position by the spring; it also includes a push rod and a movable piece, the movable piece is located in the space formed by the upper shell and the bottom shell and is connected to the push rod to form a structure that can be pushed by the push rod, the push rod is movably installed in the upper shell to form a toggleable structure; a spring arm is provided on the movable piece, the spring arm protruding towards the lower part of the handle; a protruding damping part is provided on the handle, the damping part is opposite to the spring arm, and the resistance of the spring arm to the handle is adjusted by changing the interference distance between the movable piece and the damping part by moving the push rod.

[0005] Furthermore, a dial hole is provided on the side platform at the upper edge of the upper shell, through which the rod head of the push rod extends. The main body of the push rod and the moving plate extend into the space formed by the upper shell and the bottom shell, so that the spring arm of the moving plate is opposite to the damping part.

[0006] Preferably, the movable plate and the push rod are an integral structure, with the spring arm of the movable plate extending from the push rod to form an elastic curved part, and the damping part protruding relative to the curved part of the spring arm.

[0007] Furthermore, a sleeve is provided at the bottom of the handle, and a magnetic element is provided in the sleeve as a trigger element to cooperate with the Hall element on the PCB board to form a magnetic shaft switch. The magnetic element extends downward. A plug tube is provided in the bottom shell opposite to the sleeve. The plug tube protrudes upward from the bottom of the bottom shell. When the handle is pressed, the magnetic element and the sleeve are inserted into the plug tube to trigger the switch action. A spring is sleeved on the outside of the sleeve and the plug tube and abuts against the handle and the bottom shell respectively.

[0008] Furthermore, an elastic boss is provided on the main body of the push rod, and a positioning bead is provided on the elastic boss. Several positioning grooves that match the positioning bead are provided in the upper shell and / or the bottom shell. When the push rod is moved, the positioning bead is engaged in different positioning grooves to achieve the positioning of the push rod.

[0009] Alternatively, the moving plate and the push rod are separate structures, with a fixing groove on the bottom surface of the push rod, and the top of the moving plate is inserted into the fixing groove and assembled and fixed with the push rod.

[0010] Alternatively, the moving plate and the push rod are separate structures, with an inclined surface on the side of the push rod facing the moving plate. When the push rod is moved, the inclined surface presses against the moving plate, thereby changing the interference distance between the spring arm and the damping part.

[0011] Preferably, the length of the push hole is greater than the length of the rod head, so that the push rod can be moved left and right.

[0012] Alternatively, the width of the hole can be greater than the width of the rod head, so that the push rod can be moved back and forth.

[0013] Depending on the direction of the push rod's movement, a positioning rib is provided on the side corresponding to the rod head, and a positioning groove matching the positioning rib is provided on the wall of the push hole. When the push rod is moved, the positioning rib is inserted into different positioning grooves to achieve positioning.

[0014] Alternatively, a sleeve can be provided at the bottom of the handle, and a metal rod can be placed in the sleeve as a trigger to cooperate with the coil on the PCB board to form an inductive shaft switch; or, an optical shaft switch can be formed by cooperating the lower part of the handle with the optical pair on the PCB board.

[0015] This invention features a slidable push rod in the upper shell and a protruding damping part on the button. The push rod connects to a movable plate, which can be pushed by the push rod. This alters the interference distance between the movable plate and the damping part when the push rod is moved, changing the resistance of the movable plate against the button and thus adjusting the feel for greater playability. It also solves the problem of excessive rebound force causing the switch to feel too stiff in high-speed tapping during e-sports games. Furthermore, the overall structure is simpler, with fewer parts, lower cost, and allows for convenient external adjustment of the switch. Attached Figure Description

Detailed Implementation

[0032] Example 1, referring to Figures 1-5 The adjustable-feel switch includes a handle 1, an upper shell 2, a bottom shell 3, and a magnetic element 5 (i.e., a magnet). The upper shell 2 and the bottom shell 3 are assembled and fixed. The handle 1 is installed between the upper shell 2 and the bottom shell 3 and extends partially from the upper shell 2 for pressing with a finger. The magnetic element 5 is connected to the handle 1. Pressing the handle 1 causes the magnetic element 5 to move downwards to cooperate with the Hall element on the circuit board to trigger the switch. A spring 4 is provided between the handle 1 and the bottom shell 3, and the spring 4 drives the handle 1 to rebound and reset. It also includes a push rod 6 and a moving plate. The movable piece is located in the space formed by the upper shell 2 and the bottom shell 3 and is connected to the push rod 6 to form a structure that can be pushed by the push rod 6. The push rod 6 is movably installed in the upper shell 2 so that it can be turned. A spring arm 71 is provided on the movable piece, and the spring arm 71 protrudes towards the lower part of the handle 1. A protruding damping part 12 is provided on the handle 1, and the damping part 12 is opposite to the spring arm 71. By turning the push rod 6, the interference distance between the movable piece (i.e., the spring arm 71) and the damping part 12 can be changed, so that the resistance of the spring arm 71 to the handle 1 changes, thereby adjusting the feel of the button.

[0033] A dialing hole 22 is provided on the side platform 21 at the upper edge of the upper shell 2. The rod head 61 of the push rod 6 extends out of the dialing hole 22 so that it can be turned by hand from the outside. The main body of the push rod 6 and the moving plate extend into the space formed by the upper shell 2 and the bottom shell 3, so that the spring arm 71 of the moving plate is opposite to the damping part 12.

[0034] The movable plate and the push rod 6 are an integral structure. The spring arm 71 of the movable plate extends from the bottom of the push rod 6 to form an elastic curved part. The damping part 12 protrudes relative to the curved part of the spring arm 71.

[0035] A sleeve 11 is provided at the bottom of the handle 1, and a magnetic element 5 is installed in the sleeve 11 and extends downward. A plug tube 31 is provided in the bottom shell 3 at a position opposite to the sleeve 11. The plug tube 31 protrudes upward from the bottom of the bottom shell 3. When the handle 1 is pressed, the magnetic element 5 and the sleeve 11 are inserted downward into the plug tube 31 to trigger the switch action. A spring 4 is sleeved on the outside of the sleeve 11 and the plug tube 31 and abuts against the handle 1 and the bottom shell 3 respectively to provide a rebound force on the handle.

[0036] An elastic boss 62 is provided on the main body (upper or lower) of the push rod 6, and a positioning bead 63 is provided on the elastic boss 62. Several positioning grooves that match the positioning bead 63 are provided in the upper shell 2 and / or the bottom shell 3. When the push rod 6 is moved, the positioning bead 63 is engaged in different positioning grooves to achieve the positioning of the push rod 6, so that the position of the spring arm 71 is fixed.

[0037] Example 2, refer to Figures 6-8 The movable piece 7 and the push rod 6 are separate structures. A fixing groove 64 is provided on the bottom surface of the push rod 6, and the top of the movable piece 7 is inserted into the fixing groove 64 and assembled and fixed with the push rod 6.

[0038] Example 3, referring to Figures 9-12 The movable plate 7 and the push rod 6 are separate structures. An inclined surface 66 is provided on the side of the push rod 6 facing the movable plate 7. When the push rod 6 is moved, the movable plate 7 is squeezed by the inclined surface 66, thereby changing the interference distance between the spring arm 71 and the damping part 12.

[0039] The width of the push hole 22 is greater than the width of the rod head 61, so that the push rod 6 can be moved back and forth to change the interference distance between the spring arm 71 and the damping part 12 from the front.

[0040] Alternatively, refer to Example 4. Figure 13 The length of the push hole 22 is greater than the length of the rod head 61, so that the push rod 6 can be moved left and right to change the interference distance between the spring arm 71 and the damping part 12 from the side.

[0041] Depending on the direction of the push rod 6, a positioning rib 65 is provided on the side corresponding to the rod head 61, and a positioning groove matching the positioning rib 65 is provided on the wall of the push hole 22. When the push rod 6 is pushed, the positioning rib 65 is inserted into different positioning grooves to achieve positioning.

[0042] As another implementation, the difference is that it is applied to inductor shaft triggering, and the triggering component uses a metal rod 9, eliminating the need for a magnet. For example... Figure 14 As shown, the metal rod 9 is connected and fixed to the sleeve of the handle 1. The PCB board 8 has an opening and a coil 81. By pressing the handle 1, the metal rod 9 is moved closer to or away from the coil 81 on the PCB board 8. The chip will recognize the change in inductance and trigger a signal.

[0043] Optical axis triggering can also be used, such as Figure 15 As shown, a light pair tube 82 is installed on the PCB board 8. By pressing the handle 1, light can be blocked or allowed to pass through. The chip will recognize the change in light flux to realize signal transmission.

[0044] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
