Detailed Description
In order to further describe the technical means and effects adopted by the present invention for achieving the intended purpose, the following detailed description of the specific embodiments of the present invention is given with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1 and 2, an embodiment of the present invention provides a rotary switching type audible and silent mechanism for a key switch, which includes a base 1, a pressing member 2 movably disposed on the base 1, a sliding member 3 movably connected to the pressing member 2, and an elastic movable contact 4 disposed on a side of the sliding member 3, wherein a rotary switching member 5 extending to the side of the sliding member 3 is rotatably disposed on the pressing member 2, a linkage rod 51 capable of synchronously linking the sliding member 3 with the pressing member 2 is formed on the rotary switching member 5, and the sliding member 3 and the pressing member 2 are switched between synchronous linkage and release synchronous linkage by rotating the linkage rod 51 of the rotary switching member 5, thereby realizing switching between pressing audible and silent.
By rotating the rotary switching member 5, the interlocking lever 51 of the rotary switching member 5 can be switched between the synchronous interlocking of the slider 3 and the pressing member 2 and the asynchronous interlocking of the slider 3 and the pressing member 2. Specifically, when the linkage rod 51 links the sliding part 3 and the pressing part 2 synchronously, the pressing part 2 moves up and down, and the sliding part 3 and the pressing part 2 do not move relatively, so that the sliding part 3 does not knock the pressing part 2 to generate sound, and the pressing silence effect is achieved; when the interlocking rod 51 releases the synchronous interlocking of the sliding piece 3 and the pressing piece 2, the pressing piece 2 moves up and down, and the sliding piece 3 and the pressing piece 2 move relatively, so that the sliding piece 3 knocks the pressing piece 2 to generate sound, and the pressing sound effect is achieved. Therefore, the rotary switching piece 5 with the linkage rod 51 is additionally arranged between the sliding piece 3 and the pressing piece 2, so that the sliding piece 3 and the pressing piece 2 are switched between synchronous linkage and release synchronous linkage, the switching between pressing sound and pressing silence is realized, different requirements of users are met, and the switching operation is convenient.
Regardless of whether the sliding member 3 and the pressing member 2 are in the synchronous linkage state or the release synchronous linkage state, the up-and-down movement of the pressing member 2 drives the sliding member 3 to move up and down, and the problem of whether the sliding member 3 is synchronous or not is only solved.
When the slider 3 is moved up by the pressing member 2, the slider 3 touches the elastic movable contact 4 on the side, as shown in fig. 4 and 5. When the sliding piece 3 and the pressing piece 2 are in a synchronous linkage releasing state, the sliding piece 3 is driven by the pressing piece 2 to move upwards, the sliding piece 3 meets the elastic movable contact piece 4 and applies outward acting force to the elastic movable contact piece 4, so that the elastic movable contact piece 4 is elastically deformed; then, when the pressing piece 2 drives the sliding piece 3 to move upwards synchronously, the elastic restoring force of the elastic movable contact piece 4 acts on the sliding piece 3, so that the sliding piece 3 has an upward instant acting force, and the sliding piece 3 moves upwards relative to the pressing piece 2, so that the sliding piece 3 knocks the pressing piece 2 to produce sound, and the aim of pressing and producing sound is fulfilled. Accordingly, when the sliding member 3 and the pressing member 2 are in the synchronous linkage state, no relative movement occurs between the two, so that even if the elastic movable contact 4 has an instant acting force on the sliding member 3, no knocking sound is generated.
In this embodiment, as shown in fig. 2 and 3, the rotary switching member 5 includes a mounting shaft 52 mounted on the pressing member 2, a rotary head 53 connected to the upper end of the mounting shaft 52 and exposed outside the pressing member 2, and the linkage rod 51 connected to the lower end of the mounting shaft 52, wherein the linkage rod 51 includes a supporting shaft 511 connected to the lower end of the mounting shaft 52, and a hook 512 connected to the lower end of the supporting shaft 511 for hooking the sliding member 3. When the pressing sound and pressing silence are required to be switched, the rotary head 53 may be manually rotated, and specifically, may be rotated by 90 ° to switch. When the support shaft 511 of the linkage rod 51 is supported between the pressing member 2 and the sliding member 3, as shown in fig. 2, the pressing member 2 is pressed to move downward, and the sliding member 3 moves downward synchronously due to the existence of the support shaft 511; when the pressing member 2 moves upward, the sliding member 3 moves upward synchronously due to the hook 512, and the two members do not move relatively, so as to realize the pressing silence function. When the rotating head 53 is manually rotated, the supporting shaft 511 of the linkage rod 51 rotates away from between the pressing member 2 and the sliding member 3, and the hook 512 rotates away from the sliding member 3, so that the sliding member 3 and the pressing member 2 are switched from the synchronous linkage state to the asynchronous linkage state, and the up-and-down movement of the pressing member 2 drives the sliding member 3 to move up and down, but the movements of the two are not synchronous, so that the pressing sound function can be realized.
Specifically, the supporting shaft 511 mainly comprises a lateral acting portion 5111 connected to the lower end of the mounting shaft 52, and a longitudinal supporting portion 5112 connected between the lateral acting portion 5111 and the hook 512, wherein a limiting protrusion 20 for limiting the lateral acting portion 5111 is disposed on the pressing member 2. By setting the limiting protrusion 20, the lateral acting portion 5111 is limited, and the phenomenon that the rotary switching piece 5 rotates when not receiving acting force can be effectively prevented, so that the pressing sound and pressing soundless switching action is more accurate. When the rotary switching member 5 is manually rotated, the lateral acting portion 5111 acts on the limit projection 20 by applying a force to the rotary head 53, and is rotatable outward beyond the limit projection 20, thereby realizing the rotary switching function.
In the specific structure installation, as shown in fig. 2, a relief groove 21 for the lateral acting portion 5111 to swing is formed on the pressing member 2, and the limit protrusion 20 is formed in the relief groove 21. The relief groove 21 provides a relief space for the rotation of the lateral acting portion 5111.
Of course, the rotary switching member 5 may be rotated only by forcibly rotating the rotary switching member 5 by increasing friction force on the contact surface between the mounting shaft 52 and the pressing member 2, and the rotary switching member 5 may not be rotated when no force is applied.
In this embodiment, the mounting shaft 52 and the link 51 are elastic members. Specifically, the elastic piece can be a snap spring. The elastic piece has elastic characteristics, is convenient to be matched with the limiting protrusion 20, and is convenient to rotate and operate while realizing the limiting function.
As shown in fig. 4 and 5, in the structure of the sliding member 3 and the elastic movable contact 4, in this embodiment, at least one action spring arm 41 is formed on a side of the elastic movable contact 4 near the sliding member 3, and at least one protrusion 31 corresponding to the action spring arm 41 is formed on a side of the sliding member 3 near the elastic movable contact 4. Preferably, the number of the action spring arms 41 and the number of the protruding parts 31 are 2. When the sliding part 3 moves up and down along with the pressing part 2, the sliding part 3 precisely acts on the action spring arm 41, so that the action is more precise, and the realization of the sounding function is facilitated.
For the connection between the slider 3 and the pressing member 2, the present embodiment forms at least one sliding hook groove 32 on the slider 3, and forms at least one sliding hook arm 22 hooked into the sliding hook groove 32 on the lower portion of the pressing member 2. Since the pressing member 2 is hooked into the sliding hook groove 32 by the sliding hook arm 22 to achieve connection with the sliding member 3, when the action of the rotary switching member 5 is not provided, the pressing member 2 is moved downward just when the pressing member 2 is pressed down, so that the sliding hook arm 22 slides down along the sliding hook groove 32, the sliding member 3 does not move downward, and when the pressing member 2 moves down to the upper portion to be in contact with the upper end surface of the sliding member 3, the sliding member 3 is driven to move downward together. When the pressing piece 2 moves up, the sliding hook arm 22 slides up along the sliding hook groove 32, but the sliding piece 3 does not move up, and when the pressing piece 2 moves up until the sliding hook arm 22 contacts the upper inner wall of the sliding hook groove 32, the sliding piece 3 is driven to move up together. By the above process, the asynchronous linkage action of the sliding piece 3 and the pressing piece 2 is realized, so that the sliding piece 3 is matched with the elastic movable contact piece 4, and the sound production function of the pressing piece 2 is realized.
In this embodiment, as shown in fig. 2, a positioning insertion shaft 23 is extended downward at the lower part of the pressing member 2, and the sliding hook arm 22 is formed at the outer side of the positioning insertion shaft 23; a central hole 33 into which the positioning pin 23 and the slide hook arm 22 are movably inserted is formed in the slider 3, as shown in fig. 4. Meanwhile, as shown in fig. 1, a positioning column 11 is formed on the base 1, a positioning insertion hole 111 is formed in the positioning column 11, and the positioning insertion shaft 23 is movably inserted into the positioning insertion hole 111; a return spring 6 is arranged between the pressing piece 2 and the base 1, the upper end of the return spring 6 is sleeved on the periphery of the positioning inserting shaft 111, and the lower end of the return spring is sleeved on the periphery of the positioning column 11. When the pressing piece 2 is pressed down, the return spring 6 is compressed, and when the pressing of the pressing piece 2 is released, the pressing piece 2 is driven to move up and return by the elastic restoring force of the return spring 6.
In order to facilitate the pushing member 2 to drive the sliding member 3 to move downward, as shown in fig. 2, in this embodiment, at least one driving protrusion 24 is formed on a side of the pushing member 2, and at least one driving slot 34 for the driving protrusion 24 to be snapped into is formed on the sliding member 3. When the pressing piece 2 moves downwards relative to the sliding piece 3 and the driving lug 24 is clamped into the driving clamping groove 34, the sliding piece 3 can be driven to move downwards, and the driving lug 24 is matched with the driving clamping groove 34, so that the pressing piece 2 is beneficial to driving the sliding piece 3 to move downwards stably and vertically.
In order to enable the sliding member 3 to move up and down smoothly in the base 1, in this embodiment, a guiding protrusion 35 is formed on at least two opposite outer side edges of the sliding member 3, and a guiding chute 12 into which the guiding protrusion 35 is inserted is formed on two opposite inner side walls of the base 1.
The switching type sound and silence mechanism provided in this embodiment may be applied to a push-button switch by adding the cover 7 to the base 1, as shown in fig. 6. For the conduction structure of the key switch, a dynamic and static sheet conduction structure in the existing key switch can be adopted, the elastic dynamic contact sheet 4 can be used as a moving sheet, and as shown in fig. 5, the dynamic and static sheet conduction structure is formed by combining the elastic dynamic contact sheet 4 with the static sheet 8.
The foregoing is merely a preferred embodiment of the present invention, and the technical scope of the present invention is not limited to the above embodiments, so that other structures using the same or similar technical features as those of the above embodiments of the present invention are all within the scope of the present invention.
