Detailed Description
The invention is described in further detail below with reference to the figures and specific embodiments.
As shown in fig. 1-9, the specific embodiment of the present invention is a sounding hand feeling key, the key is used for matching with an electrical element to output a switching signal, and includes a key shaft 1 and a key base 2, the key shaft 1 is embedded in the key base 2, a key reset elastic member 3 is further disposed between the key shaft 1 and the key base 2, an elastic trigger member 4 capable of triggering a switching signal is axially mounted on a sidewall of the key shaft 1 in the same direction as the key shaft 1, and the elastic trigger member 4 moves up and down relative to the key base 2 along with the key shaft 1; a stop block 201 is arranged in the key seat 2 corresponding to the position of the elastic trigger 4; when the key is pressed, the elastic trigger piece 4 moves downwards along with the key shaft 1, and the elastic trigger piece moves downwards to cross the stop block 201 to generate paragraph feeling and send out knocking sound to trigger the signal electric element to output a signal; when the key is restored, the elastic trigger piece 4 moves upwards along with the key shaft 1, passes over the stop block 201 upwards to generate a section feeling and generate a knocking sound.
In order to obtain better paragraph touch feeling, the elastic trigger 4 comprises a first elastic arm 401 and a second elastic arm 402, the top end of the first elastic arm 401 is fixedly connected with the upper end of the key shaft 1, the bottom end of the first elastic arm 401 is bent and extends upwards to form the second elastic arm 402, and the first elastic arm 401 and the second elastic arm 402 are in an L shape; under the action of an external force, the bottom end of the first elastic arm 401 and the second elastic arm 402 can tilt relative to the top end of the first elastic arm 401.
In order to obtain better paragraph touch feeling, the end of the second elastic arm 402 has an arc-shaped protrusion 403, which protrudes in a direction away from the first elastic arm 401; a knocking wall 202 is arranged on the side edge of the stop block 201; when the elastic trigger 4 moves downwards, the lower part of the arc-shaped protrusion 403 contacts the stopper 201, the resistance of the stopper 201 causes the bottom end of the first elastic arm 401 to tilt away from the side wall of the key shaft 1 adjacent to the bottom end of the first elastic arm 401 (as shown in fig. 8), and after the arc-shaped protrusion 403 passes over the stopper 201, the first elastic arm 401 rebounds and hits the side wall of the key shaft 1 (as shown in fig. 9) to generate a hitting sound when a key is pressed; when the elastic trigger 4 moves upwards, the upper part of the arc-shaped protrusion 403 contacts the stopper 201, the resistance of the stopper 201 enables the second elastic arm 402 to be extruded and deformed, and after the arc-shaped protrusion 403 passes over the stopper 201, the second elastic arm 402 rebounds and hits the hitting wall 202 to generate a hitting sound when the key is reset (see fig. 7).
The reset elastic piece 4 is a reset spring, or a silica gel piece, or a reset elastic piece.
In order to further simplify the installation process and improve the production efficiency, the signal electrical component is a light-to-tube 5, the elastic triggering piece 4 is made of opaque metal, and the bottom end of the elastic triggering piece 4 is a light path switch for blocking the conduction of a light path.

The structure is more simplified, and the punching hammer cannot be additionally arranged.
In order to obtain a trigger signal, the signal electric element is a Hall sensor, and the bottom end of the elastic trigger piece is a magnetic end. When the elastic trigger piece moves downwards to be close to the Hall sensor, the magnetic flux is changed in a sound production mode, and the Hall sensor sends out a trigger signal.
In order to facilitate the processing and installation of the elastic trigger, the top of the first elastic arm 401 is provided with a fixing hook 404. After the elastic trigger piece is installed on one side of the key shaft, the fixing hook is unfolded to be fixed, and the installation is simple, convenient and fast.
In order to save materials and reduce weight, the elastic effect of the first elastic arm is adjusted, and the middle part of the first elastic arm 401 is of a hollow structure.
In order to improve the stability and the durability of the case, the bottom of the key shaft 2 is provided with a magnetic part 7, the middle of the key base is provided with a Hall switch 6, and the magnetic part 7 corresponds to the Hall switch 6. If signal electrical element is only one, if the sound production damages after long-time use, the button just can't be used, sets up a hall switch more, can effectively improve the stability of button, provides dual fail-safe, even one of them signal electrical element damages still can normal use.
The elastic trigger is arranged, and the section touch and the knocking sound can be simply and easily realized at low cost by matching with the key shaft and the key seat, when the key shaft is pressed down, the first elastic arm of the elastic trigger accumulates force and then strikes the inner side wall of the key shaft to send the first knocking sound, when the key shaft is reset, the second elastic arm strikes the concave part of the step to send the second knocking sound, the section touch sound production effect of pressing sound production and resetting sound production can be realized only by additionally arranging one elastic trigger, and the striking touch can be greatly improved; meanwhile, the elastic trigger piece can also serve as a punch hammer, so that the key structure is further simplified, and the production cost is reduced; the assembly line is simple in structure, easy to machine and produce, simple in assembly process and high in installation efficiency, and is suitable for assembly line batch production and assembly.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any minor modifications, equivalent replacements and improvements made to the above embodiment according to the technical spirit of the present invention should be included in the protection scope of the technical solution of the present invention.
