Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments.

Referring to fig. 1 and 2, an embodiment of the present invention provides a switching type pressing sound and silence mechanism for a key switch, including a base 1, a pressing member 2 movably disposed on the base 1, and a sliding striking member 3 movably connected to the pressing member 2, wherein the pressing member 2 includes a pressing main body 21 and a positioning post 22 disposed below the pressing main body 21, a rotation switching member 4 is connected between the pressing main body 21 and the positioning post 22, the rotation switching member 4 includes a rotation switching shaft 41 movably connected between the pressing main body 21 and the positioning post 22, an upper clamping block 42 and a lower clamping block 43 disposed between the rotation switching shaft 41 and the positioning post 22, and an elastic member 44 disposed between the upper clamping block 42 and the lower clamping block 43, wherein at least a portion of the structure of the sliding striking member 3 is located between the upper clamping block 42 and the lower clamping block 43. By operating the rotation switching shaft 41, the upper clamping block 42 and the lower clamping block 43 are driven to be combined to switch between clamping and releasing the clamping of the sliding knocking piece 3, so that the sliding knocking piece 3 and the pressing piece 2 are switched between synchronous linkage and asynchronous linkage, and switching between sound pressing and soundless pressing is realized.

Specifically, through the rotation switching shaft 41 of the operation rotation switching piece 4, the rotation switching shaft 41 is rotated by a certain angle in one direction, specifically, the rotation switching shaft 41 can rotate by 90 degrees, so that the relative motion between the rotation switching shaft 41 and the positioning column 22 occurs, specifically, the rotation switching shaft 41 moves downwards, the positioning column 22 moves upwards, namely, the two move close to each other, thereby driving the upper clamping block 42 and the lower clamping block 43 to be close to each other, until the upper clamping block 42 and the lower clamping block 43 clamp the sliding knocking piece 3, at this time, the elastic piece 44 is compressed by the upper clamping block 42 and the lower clamping block 43 which are close to each other, and generates elastic deformation. At this time, the sliding knocking member 3 and the pressing member 2 are in a synchronous interlocking state, i.e., relative movement between the two does not occur. In this state, when the pressing member 2 moves up and down, the sliding striker 3 does not move relative to the pressing member 2, and the sliding striker 3 does not hit the pressing member 2 to generate sound, thereby achieving a silent pressing effect.

On the contrary, the reverse rotation of the rotation switching shaft 41 by the same angle causes the rotation switching shaft 41 and the positioning column 22 to move in reverse directions, specifically, the rotation switching shaft 41 moves upward, the positioning column 22 moves downward, the acting force on the upper clamping block 42, the lower clamping block 43 and the elastic member 44 disappears, the elastic restoring force of the elastic member 44 expands the upper clamping block 42 and the lower clamping block 43, the upper clamping block 42 moves upward, the lower clamping block 43 moves downward, and the clamping force of the upper clamping block 42 and the lower clamping block 43 on the sliding knocking member 3 disappears. At this time, the sliding knocking member 3 and the pressing member 2 are in a non-synchronous interlocking state, that is, a relative movement can occur therebetween. In this state, when the pressing member 2 moves up and down and the sliding striker 3 and the pressing member 2 move relatively, the sliding striker 3 strikes the pressing body 21 of the pressing member 2 to generate sound, thereby achieving a pressing sound effect.

Therefore, the rotation switching piece 4 is additionally arranged between the pressing piece 2 and the sliding knocking piece 3, so that the sliding knocking piece 3 and the pressing piece 2 are switched between synchronous linkage and asynchronous linkage, switching between pressing sound and pressing soundless sound is realized, different requirements of users are met, and switching operation is convenient.

The sliding knocking piece 3 and the pressing piece 2 are in a synchronous linkage state or an asynchronous linkage state, and the up-and-down movement of the pressing piece 2 can drive the sliding knocking piece 3 to move up and down, so that the problem of synchronization is only solved.

In the present embodiment, as shown in fig. 2, fig. 7 and fig. 8, the rotation switching shaft 41 includes a switching shaft main body 411 and a downward movement guiding block 412 disposed at the periphery of the switching shaft main body 411, wherein the upper end of the switching shaft main body 411 is a rotation operating portion 4111, and when the switching with sound and without sound needs to be pressed, the rotation operating portion 4111 is directly acted on, specifically, a notch 41111 matched with a screwdriver may be formed on the rotation operating portion 4111, and as shown in fig. 7, the operation can be performed by directly placing the screwdriver in the notch 41111; a screw groove 4112 is formed upward at the lower end of the switching shaft main body 411, and an internal thread 4113 is formed inside the screw groove 4112; the upper clamp block 42 is located below the down-moving guide block 412.

In the present embodiment, as shown in fig. 2 to 5, the positioning column 22 includes a lower positioning column 221, an upper positioning column 222 formed at the upper end of the lower positioning column 221 and inserted into the screw thread groove 4112, and a supporting platform 223 formed between the upper positioning column 222 and the lower positioning column 221, wherein an external thread 2221 matched with the internal thread 4113 is formed on the periphery of the upper positioning column 222; the lower clamp block 43 is located above the support table 223. Upper positioning post 222 is inserted into screw groove 4112 and screwed with internal thread 4113 by external thread 2221. Since the positioning post 22 does not rotate, when the rotation switching shaft 41 rotates and moves downward, the positioning post 22 is forced to move upward under the action of the internal thread 4113 and the external thread 2221, so as to drive the upper clamping block 42 and the lower clamping block 43 to approach each other to clamp the sliding knocking member 3. On the contrary, since the positioning post 22 does not rotate, when the rotation switching shaft 41 rotates reversely and moves upwards, the positioning post 22 is forced to move downwards under the action of the internal thread 4113 and the external thread 2221, so that the acting force exerted on the upper clamping block 42, the lower clamping block 43 and the elastic member 44 disappears, and the elastic restoring force of the elastic member 44 expands the upper clamping block 42 and the lower clamping block 43, so that the clamping force of the upper clamping block 42 and the lower clamping block 43 on the sliding knocking member 3 disappears.

Therefore, the rotation switching shaft 41 and the positioning column 22 are screwed to each other, so that the rotation switching shaft 41 and the positioning column 22 can be moved relative to each other in the vertical direction, and the upper and

lower clamping blocks

42 and 43 can be switched between clamping and releasing the sliding strikers 3, thereby switching between sound pressing and soundless pressing.

When the rotation switching shaft 41 is forced to rotate, in order to realize the up-and-down movement, in this embodiment, at least one positioning protrusion 211 is formed on the pressing body 21, as shown in fig. 6 and 8, and at least one positioning groove 4121 matched with the positioning protrusion 211 is formed on the downward movement guide block 412, as shown in fig. 7. Preferably, the number of the positioning protrusions 211 and the number of the positioning clamping grooves 4121 are two, and the positioning protrusions and the positioning clamping grooves are arranged oppositely. In the initial state, the positioning projection 211 is caught in the positioning catching groove 4121. Since the positioning protrusion 211 of the pressing body 21 does not rotate, when the rotation switching shaft 41 is rotated in one direction, the positioning engaging groove 4121 is forced to leave the positioning protrusion 211 under the positioning action of the positioning protrusion 211, so that the positioning protrusion 211 meets the other part of the downward movement guide block 412 except the positioning engaging groove 4121, thereby forcing the rotation switching shaft 41 to move downward. On the contrary, when the rotation switching shaft 41 is subjected to a reverse rotation force, the positioning notch 4121 rotates to meet the positioning protrusion 211, so that the positioning protrusion 211 is re-engaged in the positioning notch 4121 to force the rotation switching shaft 41 to move up.

Therefore, by pressing the positioning protrusion 211 of the main body 21 and the positioning groove 4121 of the downward moving guide block 412 matching with the positioning protrusion 211, the upward and downward movement of the rotation switching shaft 41 can be realized.

Specifically, as shown in fig. 6 and 7, the positioning protrusion 211 and the positioning slot 4121 are respectively arc-shaped, and a first guiding inclined surface 4122 is respectively formed on two inner side walls of the positioning slot 4121, and a second guiding inclined surface 2111 is respectively formed on two sides of the positioning protrusion 211. Due to the matching design of the first guiding inclined surface 4122 and the second guiding inclined surface 2111, when the rotation switching shaft 41 is forced to rotate, the positioning engaging groove 4121 is favorably separated or engaged with the positioning protrusion 211, so that the downward movement guiding block 412 of the rotation switching shaft 41 can move smoothly relative to the pressing body 21.

For the installation of the rotation switching shaft 41, as shown in fig. 6, the present embodiment forms a center insertion hole 212 into which the upper portion of the switching shaft main body 411 is inserted on the pressing main body 21, and the positioning projection 211 is formed on the lower end surface outer side of the center insertion hole 212.

In this embodiment, as shown in fig. 1 and 5, the upper clamping block 42 includes an upper ferrule 421 sleeved on the periphery of the switching shaft main body 411 and located below the downward moving guide block 412, and two upper clamping pieces 422 formed on two opposite sides of the upper ferrule 421; the lower clamping block 43 comprises a lower ferrule 431 sleeved on the periphery of the upper positioning column 222 and positioned at the upper end of the supporting platform 223, and two lower clamping pieces 432 formed at two opposite sides of the lower ferrule 431; at least part of the upper structure of the sliding knocking piece 3 is positioned between the upper clamping piece 422 and the lower clamping piece 432, and when the sliding knocking piece 3 is clamped, the upper clamping piece 422 and the lower clamping piece 432 which correspond to each other up and down are used for clamping.

In this embodiment, as shown in fig. 4 and 6, a central positioning groove 213 for the downward moving guide block 412 to be inserted and movable and two side positioning grooves 214 for the two upper clamping pieces 422 to be inserted and oppositely disposed are respectively formed at the lower end of the pressing body 21, and the positioning protrusion 211 is formed in the central positioning groove 213. The center positioning groove 213 provides a space for the downward movement of the downward movement guide block 412, and limits the rotation range of the downward movement guide block 412 to prevent the downward movement guide block from moving laterally, thereby improving the accuracy of the rotation and longitudinal movement of the downward movement guide block. When the sliding knocking piece 3 and the pressing piece 2 are switched to be in the asynchronous linkage state, the two upper clamping pieces 422 are hidden into the two side positioning grooves 214, and meanwhile, the downward moving guide block 412 is hidden into the central positioning groove 213, so that the relative movement of the sliding knocking piece 3 and the pressing piece 2 is not influenced.

In the present embodiment, as shown in fig. 2 to 5, the elastic element 44 is an upper return spring 44' sleeved on the lower portion of the switching shaft main body 411 and the periphery of the upper positioning column 222, and the upper return spring 44' is abutted between the upper ring 421 and the lower ring 431, so as to support the upper ring 421 and the lower ring 431 by the elastic force of the upper return spring 44 '.

As for the connection relationship between the sliding striker 3 and the pressing member 2, as shown in fig. 3 and 4, in the present embodiment, at least two sliding hook grooves 31 are oppositely disposed on the sliding striker 3, and at least two sliding hook arms 215 hooked into the sliding hook grooves 31 are extended downward from the pressing body 21. When the sliding knock part 3 and the knock part 2 are in the asynchronous linkage state, the knock main body 21 of the knock part 2 hooks into the sliding hook groove 31 through the sliding hook arm 215 to realize the connection with the sliding knock part 3, meanwhile, because the rotation switching part 4 only plays a role of connection, the knock part 2 just pressed down, the knock part 2 moves down, so that the sliding hook arm 215 slides down along the sliding hook groove 31, the sliding knock part 3 does not move down, and when the knock part 2 moves down to contact the upper end face of the knock main body 21 and the sliding knock part 3, the knock part 3 is driven to move down together. When the pressing member 2 moves upward, the sliding hook arm 215 slides upward along the sliding hook groove 31 without moving the sliding hammer 3 upward, and when the pressing member 2 moves upward and the sliding hook arm 215 contacts the upper inner wall of the sliding hook groove 31, the sliding hammer 3 is driven to move upward together. By the above process, the asynchronous interlocking action of the sliding striker 3 and the pusher 2 is realized, and in the up-and-down moving process of the asynchronous interlocking of the sliding striker 3 and the pusher 2, the sound is generated when the sliding striker 3 strikes the pressing body 21 of the pusher 2.

Meanwhile, the upper clip 422 is located above the sliding knocking part 3, the lower clip 432 extends into the sliding hook groove 215, and an abdicating opening 2151 for the upper clip 422 and the lower clip 432 to pass through is formed on the sliding hook arm 215, so that the sliding hook arm 215 and the upper clip 422, and the sliding hook arm 215 and the lower clip 432 are not interfered with each other and function respectively.

Meanwhile, the sliding hook arm 215 is formed outside the positioning column 22; a central hole 32 for movably inserting the positioning post 22 and the sliding hook arm 215 is formed on the sliding knocking member 3.

As for the installation manner between the lower positioning column 221 and the base 1, as shown in fig. 2 and fig. 9, a positioning groove 11 is formed on the base 1 in a concave manner, a positioning insertion shaft 12 is provided in the positioning groove 11 in a convex manner, a positioning insertion hole 2211 is formed in the lower positioning column 221, and the positioning insertion shaft 12 is movably inserted into the positioning insertion hole 2211; a lower return spring 5 is disposed between the support table 223 and the base 1, the upper portion of the lower return spring 5 is sleeved on the periphery of the lower positioning column 221, and the lower portion thereof is embedded in the positioning groove 11 and sleeved on the periphery of the positioning spindle 12. When the pressing piece 2 is pressed downward, the lower return spring 5 is compressed, and when the pressing piece 2 is released, the elastic restoring force of the lower return spring 5 drives the pressing piece 2 to move upward and return.

In order to allow the sliding strike 3 to move up and down smoothly in the base 1, in this embodiment, a guide protrusion 33 is formed on at least two opposite outer side edges of the sliding strike 3, as shown in fig. 3, and a guide sliding groove 13 into which the guide protrusion 33 is inserted is formed on two opposite inner side walls of the base 1, as shown in fig. 9.

When the switching type push silent mechanism provided in the present embodiment is applied to a push switch, the upper cover 7 may be added to the base 1, as shown in fig. 10. As for the conducting structure of the key switch, a moving-stator conducting structure of the existing key switch can be adopted, as shown in fig. 11, a moving-stator conducting structure is formed by combining a moving plate 8 and a stator plate 9.
