Problems solved by technology

Under the action of the spring, the central shaft assembly rebounds upwards. When the raised part 31 and the raised part 32 of the movable slider 3 of the central shaft movable assembly crossed the valley peak 61 of the metal shrapnel 6, due to the protrusions 31 and 32 The factor of the contour shape, the angle setting of the contour does not match the slope of the metal shrapnel, the metal shrapnel cannot generate an upward reverse force, and it cannot make the movable slider move quickly in the upward direction, so that the springback cannot be generated. Paragraph sense and secondary impact sound

Embodiment 1

[0086] The switch module structure of the integrated input device with two tactile impact sounds and photoelectric control involved in the present invention, the isometric exploded structure diagram of the specific embodiment 1 is as follows Figure 11 As shown, the frontal view of the decomposition structure diagram is shown in Figure 12 As shown, the sectional view along the A-A direction is as follows Figure 13 As shown, the sectional view along the B-B direction is as follows Figure 14 shown. It consists of an upper cover 11, a central shaft movable assembly (a cross key shaft 12 and a "C"-shaped movable slider 13), a spring 14, a first prism 15 and a second prism 16, a first metal dome 17 and a second metal dome 18 , lower cover 19, SMDIR tube 23 (surface-mounted infrared light-emitting diode or laser diode), SMDPT tube 24 (surface-mounted photoelectric receiver tube), and PCB board 20 (printed circuit board). The central axis movable assembly includes a cross key s...

Embodiment 2

[0107] The switch module structure of the integrated input device that produces two tactile impact sounds and photoelectric control involved in the present invention is located on the other side of the key shaft as the control mechanism of the photoelectric key switch in the second specific embodiment, and the control mechanism of the key switch is principle such as Figure 22 shown. The third prism 25 and the fourth prism 26 located above the SMDIR tube 23 and the SMDPT tube 24 are free-form surface prisms. In the free-form surface prism, the inclined total reflection surfaces 252 and 262 above it are free-form surfaces. The function of (converging) and deflecting light is an off-axis paraboloid, off-axis quadratic surface, or an inclined polynomial surface, and the incident surfaces (exit surfaces) 251 and 261 below it are both planes.

Embodiment 3

[0111] The switch module structure of the integrated input device that produces two tactile impact sounds and photoelectric control involved in the present invention is located on the other side of the key shaft as the control mechanism of the photoelectric key switch in the specific embodiment 3, and the control mechanism of the key switch principle such as Figure 23 shown. The fifth prism 35 and the sixth prism 36 above the SMDIR pipe 23 and the SMDPT pipe 24 are oblique Fresnel total reflection prisms, and the oblique total reflection surfaces 352 and 362 of the oblique Fresnel total reflection prism above it It is a zigzag Fresnel total reflection surface, which has the function of collimating (or converging) and deflecting light, and the incident surface 351 and the outgoing surface 361 below it are both planes.

[0112] When the central shaft movable assembly (comprising the cross key shaft 12 and the "C" shape movable slider 13) is pressed under force, the raised port...

Abstract

The invention discloses a photoelectric control integrated input device switch module capable of generating twice touch click sounds, which comprises an upper cover, a central shaft active assembly, metal elastic sheets, a spring, optical elements, small hole diaphragms, a light emitting device, a light receiving device, a lower cover and a PCB. Two sides of a central key shaft are respectively provided with a sound production mechanism and a control mechanism, the sound production mechanism is located at one side of the central key shaft and comprises a convex part of an active sliding block and the metal elastic sheet for generating a key click sound; and the control mechanism comprises a convex part of the central key shaft, the optical element, the metal elastic sheet, a light baffling sheet whose edge is bent for a certain angle, and light emitting and receiving devices for controlling off or on of a light path. The module of the invention adopts an independent new click sound generation structure, on and off of the switch are not influenced, convenience, diversity and stability of design are achieved, and diverse different click sound can be created.

Description

technical field [0001] The invention relates to the technical field of input equipment for electronic devices, in particular to a switch module for an input equipment integrated with two tactile impact sounds and photoelectric control. Background technique [0002] Mechanical keyboard (English: Mechanical Keyboard) or mechanical axis keyboard is a type of keyboard that is currently on the market. From a structural point of view, each key of the mechanical keyboard has a separate Switch (that is, a switch). Control the closing of the connected circuit. This switch is also called "shaft". Since each button is composed of an independent micro-motion mechanism, the button has a strong sense of paragraph, which produces a special feel suitable for gaming and entertainment. Therefore, it is usually used as a switch. More expensive computer peripherals for high-end gaming, also ideal for programmers. From the early days of the keyboard to the present, the mechanical keyboard has n...
