As shown in fig. 6, before the key sheet 1 is pressed, the key spring 5 is slightly compressed, the spring cap 4 is lifted by the key spring 5, and the key sheet 1 is lifted by the top of the spring cap in the reset state; the key board 1 is pressed downwards, the spring cap 4 moves downwards on the bracket 2, the key spring 5 is further compressed, and the force for pressing the key board 1 downwards is larger and larger; by pressing the key board 1, the rebounding bracket connecting shaft 311 at the left end of the rebounding bracket 31 is driven by the key board connecting rod 11 to move downwards, at this time, the rebounding bracket 31 and the rebounding baffle 32 rotate around the shaft holes on the bracket 2 respectively, the right end of the rebounding bracket 31 moves upwards to drive the left end of the rebounding baffle 32 to move upwards as well, the rebounding spring 33 is compressed gradually, when the key board moves downwards to the state shown in fig. 7, the rebounding spring 33 is compressed to the minimum length state to reach the yield point of the compressed spring, if the key board 1 is continuously pressed downwards, the rebounding bracket connecting shaft 311 at the left end of the rebounding bracket 31 continues to move downwards, the rebounding bracket 31 and the rebounding baffle 32 continue to rotate, the larger compression force of the rebounding spring 33 can be released suddenly to drive the left end of the rebounding bracket 31 to slide downwards rapidly until the rebounding spring 33 is extended to the maximum limit position, as shown in fig. 8, at this time, the right end of the rebound bracket 31 and the left end of the rebound baffle 32 both move to the highest point, and at the same time, the spring cap 4 is pressed down and slides to the lowest position, and the spring cap 4 presses the key 7 to trigger the key function.

In the process that the key board 1 is pressed down to the lowest position from the highest position, the pressing force of the key board 1 is gradually increased and suddenly reduced, and in the moment that the key force is suddenly reduced, a strong prompt feeling is provided, and then the key function is triggered in a short time, so that the problem that the key force is linearly increased and the key pressing feeling is not provided in the existing scheme is solved.

After the key board 1 is released, the key spring 5 provides elastic force to the spring cap 4 in the state of maximum compression amount, the spring cap 4 drives the key board 1 to move upwards, the self-rebounding assembly 3 is compressed to the maximum compression amount and suddenly released through the rebounding spring 33 which is the same as the pressing process, and the key board 1 can instantly return to the reset state.

According to the button board by pressing the in-process that the button function was pressed and is triggered, the in-process that the button board kick-backed to the reset position is triggered from the button, from resilience subassembly and button spring interact, it has the suggestion sense to have formed to press, the pressing force increases to and can assist from resilience subassembly after the certain degree and provide the pressing force, and there is the effect of pressing the suggestion, the button resets the in-process, the subassembly can realize the quick resilience of button board from rebounding and resets, two strokes have all formed better button and have felt and experienced.

Finally, it should be noted that: the embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.

The above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
