DETAILED DESCRIPTION

[0022] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments, wherein the same components are represented by the same reference numerals.

[0023] See also Figures 1 to 6 The embodiment of the utility model discloses an optical switch game console button, including a keycap 10, a grating switch 20, a circuit board 30 and a housing 40.

[0024] like Figure 1 、 2 、 Figure 3 as well as Figure 6 As shown, a circuit board 30 and a grating switch 20 are assembled in the housing 40 from bottom to top. The bottom surface of the circuit board 30 is spaced and electrically connected with a light emitting element 31, an optical signal receiving element 32 and a control chip 33. The circuit board 30 is provided with a through hole 34 between the light emitting element 31 and the optical signal receiving element 32. The grating switch 20 includes a reset mechanism 21 and a grating baffle 22 that can be raised and lowered to pass through the reset mechanism 21. The keycap 10 is fixed to the top of the grating baffle 22 and slidably cooperates with the upper port of the housing 40. The bottom end of the grating baffle 22 can movably pass through the through hole 34 and can extend and retract in and out of the through hole 34 as the keycap 10 is raised and lowered, thereby blocking or opening the light path between the light emitting element 31 and the optical signal receiving element 32.

[0025] The optical switch game console button of the present invention is as follows: under normal conditions, the bottom end of the grating baffle 22 is located in the through hole 34, the optical path between the optical signal receiving element 32 and the light emitting element 31 is connected, and the logic circuit receives the optical path connection signal to control the switch circuit to be disconnected, that is, the switch is in the off state; when the keycap 10 is pressed downward, the grating baffle 22 moves downward, and the bottom end of the grating baffle 22 extends out of the through hole 34 and blocks between the light emitting element 31 and the optical signal receiving element 32, the optical path between the optical signal receiving element 32 and the light emitting element 31 is disconnected, and the logic circuit cannot receive the optical path connection signal to control the switch circuit to be closed. At this time, the switch is in the closed state. When the keycap 10 is loosened, under the action of the reset mechanism 21, the grating baffle 22 automatically moves up until the bottom end of the grating baffle 22 extends into the through hole 34, and the switch is in the off state.

[0026] In the embodiment of the present invention, it should be noted that the reset mechanism 21 is a mature component in the prior art, which is composed of a fixing seat and a reset spring, and the specific structure is not repeated here.

[0027] like Figure 6 As shown, in the embodiment of the present invention, the through hole 34 is opened in the center of the circuit board 30, and the grating baffle 22 is loosely matched with the through hole 34, which can improve the accuracy and stability of the matching between the through hole 34 of the circuit board 30 and the grating baffle 22.

[0028] like Figure 2 、 Figure 3 as well as Figure 4 As shown, in the embodiment of the present invention, two first elastic clips 41 are symmetrically provided on the inner bottom surface of the housing 40. The outer edge of the top surface of the reset mechanism 21 is provided with a snap-fitting groove 211 that cooperates with the first elastic clips 41. The first elastic clips 41 snap-fit ​​with the snap-fitting grooves 211, thereby snapping the circuit board 30 and the grating switch 20 into the housing 40. Specifically, there are two snap-fitting grooves 211, which are arranged in a one-to-one correspondence with the first elastic clips 41. The first elastic clips 41 are inverted L-shaped structures, with their ends snapping into the snap-fitting grooves 211 to secure the reset mechanism 21 into the housing 40. A gap is provided between the first elastic clips 41 and the inner wall of the housing 40 to ensure that the first elastic clips 41 can elastically deform.

[0029] like Figure 3 、 Figure 4 、 Figure 5 as well as Figure 6 As shown, in an embodiment of the present invention, a second elastic clip 212 is symmetrically provided on the bottom surface of the reset mechanism 21, and a clip avoidance hole 38 is provided on the outer edge of the circuit board 30. The bottom end of the second elastic clip 212 bypasses the clip avoidance hole 38 and presses against the bottom surface of the circuit board 30. The provision of the second elastic clip 212 can connect the reset mechanism 21 and the circuit board 30 into one body, so that the whole can be assembled in the housing 40.

[0030] In the embodiment of the present invention, the housing 40 is made of light-shielding material to protect the light path from being affected by external light sources.

[0031] like Figure 4 As shown, in the embodiment of the present invention, two external buckles 42 are symmetrically provided on the outer ring wall of the housing 40. The external buckles 42 can be elastic buckles. The external buckles 42 are provided to facilitate fixing the button on the game console.

[0032] like Figure 6As shown, in an embodiment of the present invention, a power line 35, a ground line 36 and a signal line 37 are further provided on the bottom surface of the circuit board 30 to facilitate electrical connection of various components of the game console, and an opening is further provided on the bottom surface of the housing 40 for the power line 35, the ground line 36 and the signal line 37 to pass through.

[0033] An optical switch game console button disclosed in an embodiment of the present utility model realizes the emission and reception of light signals by using a light emitting element 31 and a light signal receiving element 32, and utilizes a grating baffle 22 to open or block the light signal to realize the on and off of the switch. This method completely avoids the existence of metal contacts, thereby effectively eliminating the problem of metal contact oxidation. At the same time, it also eliminates the unstable factors in the circuit caused by contact, friction or mechanical jitter of the metal contacts, thereby greatly improving the service life, sensitivity and stability of the button.

[0034] The above-mentioned technical scheme of the present invention is described in detail with reference to specific embodiments. The specific embodiments described are used to help understand the concept of the present invention. Derivations and modifications made by those skilled in the art based on the specific embodiments of the present invention also fall within the scope of protection of the present invention.
