Description

Technical Field

[0001] The utility model relates to a key switching mechanism, in particular to a switching mechanism for a trigger key of a game controller. Background Art

[0002] Currently, to adapt to the needs of different gaming scenarios, game controllers add a "switching assembly" to the trigger button to achieve different trigger application modes, allowing the trigger button to switch into different key modes. Chinese Patent Publication No. CN 219983886 U, entitled "Trigger Trigger Mode Switching Structure and Handle," discloses a trigger trigger mode switching structure comprising: a fixed base and a trigger switch; a movably mounted trigger assembly; and a switching assembly comprising a rotatable switching bracket and a movable member movably mounted on the switching bracket. The switching bracket is rotated to offset the movable member from the trigger assembly, and the switching assembly is in a first position. Pulling the trigger assembly achieves a first trigger trigger mode. The switching bracket is rotated to align the movable member with the trigger assembly, and the switching assembly is in a second position. Pulling the trigger assembly causes the movable member to press the trigger switch, achieving a second trigger trigger mode. However, this switching structure incorporates a movable member on the switching bracket that acts as a transfer mechanism. The rotation of the switching bracket allows the movable member and the trigger assembly to align or offset. When the movable part and the trigger assembly are switched to a corresponding position, when pressing the trigger assembly, the trigger assembly must first be pressed to one end of the movable part, and then the other end of the movable part resists and presses the trigger switch. This not only adds an intermediate pressing stroke, resulting in two resisting hand feelings, but also directly affects the normal pressing of the trigger assembly when the compression spring that drives the movable part to reset ages. In addition, due to the provision of a transfer mechanism (movable part and corresponding spring and mounting seat, etc.), and then the switch is installed to the front side of the movable part, the components are numerous, and the layout thereof causes the entire mechanism to be larger in size and complex to assemble, requiring a larger internal space of a game controller, making it difficult to apply to small game controllers. Therefore, developing a switching mechanism for the trigger key of a game controller has become a problem to be solved urgently by those skilled in the art. Utility Model Content

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Example 1: Figures 1 to 5As shown, a switching mechanism for a trigger button of a game controller includes a fixed bracket 1 and a trigger key cap 2. The trigger key cap 2 is hinged to the upper part of the fixed bracket 1 and is provided with a trigger torsion spring 9. A first rotating shaft 101 is provided in the middle of the fixed bracket 1 and is installed with a swing seat 3. One end of the swing seat 3 is provided with an axis hole 301 and is installed at the first rotating shaft 101. A first torsion spring 4 is provided between the swing seat 3 and the first rotating shaft 101. A dual switch module 5 is fixed to the swing seat 3 by a snap structure 302 and a positioning pin 303. The dual switch module 5 includes a key circuit board 501. The key circuit board 501 is connected to the first rotating shaft 101 by a flexible cable 50 4 is connected to the main control circuit board 6 of the game controller. The key circuit board 501 is equipped with a tactile switch 502 and a Hall effect sensor 503. The bottom of the trigger keycap 2 is equipped with a touch pressure end 201 and a Hall effect magnet 202 corresponding to the tactile switch 502 and the Hall effect sensor 503. The Hall effect magnet 202 and the Hall effect sensor 503 form a Hall effect switch. Driven by the trigger keycap 2, the Hall effect magnet 202 can move closer to or farther from the Hall effect sensor 503, thereby changing the magnetic field strength received by the Hall effect sensor. The Hall effect voltage changes with the change in magnetic field strength: the stronger the magnetic field, the higher the voltage, and the weaker the magnetic field, the lower the voltage. The Hall effect sensor can thus convert the magnetic signal into an electrical signal, which is amplified by an internal amplifier and then used for signal transmission. A second rotating shaft 102 is provided at the lower part of the fixed bracket 1, and a switching switch 7 for pushing the swing seat 3 is installed. The switching switch 7 is a rotary pushing switch. The switching switch 7 is provided with a pushing portion 701 and a control end 702. The pushing portion 701 is provided with a positioning plane 703. When the switching switch 7 is operated, the pushing portion 701 can push up the swing seat 3 or make the swing seat 3 fall back. A second torsion spring 8 is provided between the switching switch 7 and the second rotating shaft 102.

[0026] When working, Figure 6 、 Figure 7 The figure shows the state where the dual switch module 5 is not lifted. At this time, the detection switch (not shown) set on the main control circuit board 6 detects that the dual switch module 5 is not lifted and transmits a signal to the single chip microcomputer of the main control circuit board 6. The main circuit board 6 disconnects the touch switch circuit, making the Hall switch in the working state and the touch switch in the non-working state. When the trigger key cap 2 is pressed, as shown in FIG. Figure 8 As shown in the figure (with the trigger key cap in perspective), in this state, the distance between the linear switch trigger 202 and the linear switch sensor 503 changes, and the linear switch sensor 503 can sense the movement of the trigger key cap 2, while the contact end 201 on the trigger key cap 2 cannot contact the touch switch 502. In this state, the trigger key is a linear switch with no touch feeling.

[0027] like Figure 9 、 Figure 10The figure shows the dual switch module 5 in the lifted state. At this time, the detection switch (not shown) set on the main control circuit board 6 detects that the dual switch module 5 is in the lifted state and transmits a signal to the single-chip microcomputer of the main control circuit board 6. The main control circuit board 6 disconnects the Hall switch circuit, causing the Hall switch to be inactive and the touch switch to be active. In this state, the contact pressure end 201 at the bottom of the trigger key cap 2 is very close to the touch switch 502. When the trigger key cap 2 is lightly pressed, the contact pressure end 201 at the bottom of the trigger key cap 2 contacts the touch switch 502, which has a touch feeling, usually accompanied by a clicking sound. The Hall switch on the trigger key cap 2 is in the inactive state. In this state, the trigger key is a touch switch with a touch feeling.

[0028] Example 2: This example only replaces the "Hall switch" in Example 1 with an "optical switch", and the rest of the structure is the same. Figures 1 to 5 As shown, a switching mechanism for a trigger button of a game controller includes a fixed bracket 1 and a trigger key cap 2, the trigger key cap 2 is hinged to the upper part of the fixed bracket 1, and is provided with a trigger torsion spring 9, a first rotating shaft 101 is provided in the middle of the fixed bracket 1, and a swing seat 3 is installed, an axis hole 301 is provided at one end of the swing seat 3, and is installed at the first rotating shaft 101, a first torsion spring 4 is provided between the swing seat 3 and the first rotating shaft 101, a dual switch module 5 is fixed to the swing seat 3 by a snap structure 302 and a positioning pin 303, the dual switch module 5 includes a key circuit board 501, the key circuit board 501 is connected to the main control circuit board 6 of the game controller through a flexible cable 504, a light touch switch 502 and an optical sensor element are provided on the key circuit board 501, and the optical sensor element includes a light emitting element 505 and a photosensitive element 506 (such as Figure 11 As shown in the figure, the bottom of the trigger key cap 2 is provided with a touch pressure end 201 and a light shielding portion / light transmitting portion 203 corresponding to the tactile switch 502 and the optical sensor element. The light shielding portion / light transmitting portion 203 and the optical sensor element constitute an optical switch; the light shielding portion / light transmitting portion 203 moves between the light emitting element 505 and the photosensitive element 506 under the drive of the trigger key cap 2, thereby changing the amount of light received by the photosensitive element, and then generating a corresponding resistance value. The stronger the light, the smaller the resistance of the photosensitive element, and the weaker the light, the larger the resistance of the photosensitive element. The fixed bracket 1 is provided with a second rotating shaft 102 at the lower portion and is mounted with a switch 7 for pushing the swing seat 3. The switch 7 is a rotary push switch and includes a push portion 701 and a control end 702. The push portion 701 is provided with a positioning plane 703. When the switch 7 is operated, the push portion 701 can push up the swing seat 3 or make the swing seat 3 fall back. A second torsion spring 8 is provided between the switch 7 and the second rotating shaft 102. The working principle of this embodiment is the same as that of the first embodiment.

[0029] In other embodiments, the touch switch in the above embodiment can be replaced with a micro switch; the switch 7 can also be a push-pull type push switch (such as Figure 12 as shown), push-type push switch or knob push switch.
