[0016] The utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0017] See also Figure 1 , Figure 2 and Figure 3 An embodiment of the full-area uniform pressure control plate of the utility model is applied between a bottom plate unit 91 and a pressure plate 92. The bottom plate unit 91 includes a base plate 911 and a reed 912 (generally referred to as Dome) arranged at the center of the base plate 911.

[0018] See also Figure 2 , Figure 3 and Figure 4 The full-area uniform pressing control panel includes a surrounding frame 2, two floating frames 3, and a movable part 4.

[0019] The surrounding frame 2 includes two first fixing portions 21 spaced apart along a first direction X, and two second fixing portions 22 spaced apart along a second direction Y perpendicular to the first direction X. The first fixing portion 21 extends along the second direction Y, and the second fixing portion 22 extends along the first direction X. Each of the second fixing portions 22 is connected to the first fixing portion 21 at two opposite sides along the first direction X.

[0020] Each first fixing portion 21 has a first side region 211 extending along the second direction Y, and two shielding regions 212 spaced apart along the second direction Y and extending along the first direction X from the first side region 211 toward another first side region 211 .

[0021] The floating frames 3 are arranged at intervals along the first direction X and are located between the first fixing portions 21. Each of the floating frames 3 is connected to the second fixing portions 22 at two opposite sides along the second direction Y. Each floating frame 3 includes two screw holes 31, and each of the shielding areas 212 extends from the respective first side areas 211 to the top of one of the adjacent floating frames 3. In this embodiment, the floating frames 3 are flexible and can bend under force.

[0022] See also Figure 4 , Figure 5 and Figure 6 The movable member 4 includes a compression zone 41 disposed on the top surface of the floating frame 3, two first extension zones 42 spaced apart along the first direction X and extending from the compression zone 41 to the bottom of one of the adjacent second fixing portions 22 along the second direction Y, and two second extension zones 43 spaced apart along the first direction X and extending from the compression zone 41 to the bottom of another of the adjacent second fixing portions 22 along the second direction Y.

[0023] The pressure-bearing area 41 has four through holes 411 corresponding to the screw holes 31 respectively.

[0024] See also Figure 2 , Figure 4 and Figure 5 During assembly, the surrounding frame 2 is set on the base plate 911, and the first extension area 42 of the movable part 4 is inserted under one of the second fixing parts 22, and then the second extension area 43 of the movable part 4 is inserted under another of the second fixing parts 22, so that the center of the bottom of the pressure area 41 is facing downward against the top of the spring leaf 912, and then four structural screws 93 are passed through the through holes 411 and screwed into the screw holes 31, so that the movable part 4 and the floating frame 3 can be fixed, and finally the pressing plate 92 is fixed to the movable part 4 to complete the assembly operation.

[0025] See also Figure 7 When the pressing plate 92 is pressed downward by a force on one side along the second direction Y, for example Figure 7 When the left side is pressed, the movable member 4 is linked and pressed downward against the spring sheet 912. At this time, the first extension area 42 on the left side is forced to move downward, and the second extension area 43 on the right side moves upward with the spring sheet 912 as a fulcrum, and is limited by the second fixing portion 22 above, so that it is subjected to feedback force when pressed. If the right side is pressed, similarly, the first extension area 42 on the left side is also limited by the second fixing portion 22 above, and a feedback force is generated.

[0026] See also Figure 8 , and when the pressing plate 92 is pressed down by force on one side along the first direction X, for example Figure 8 When the left side is pressed, the movable member 4 is linked and pressed downward against the spring sheet 912. At this time, the floating frame 3 on the left side is forced to bend downward, while the floating frame 3 on the right side is bent upward with the spring sheet 912 as a fulcrum and is limited by the shielding area 212 above, so that it is subjected to feedback force when pressed. If the right side is pressed, similarly, the floating frame 3 on the left side is also limited by the shielding area 212 above, and a feedback force is generated.

[0027] See also Figure 7 and Figure 8 Similarly, when the pressing plate 92 is pressed down by force at a corner, one of the first extension areas 42 or one of the second extension areas 43 adjacent to the diagonal corner will be limited by the second fixed portion 22 above, and one of the floating frames 3 adjacent to the diagonal corner will also be limited by the shielding area 212 above. When the two points are limited at the same time, feedback force is generated.

[0028] Since when pressure is applied to different positions, the positions in the opposite directions will be limited and feedback force will be generated, thus achieving a uniform pressing effect in the entire area, giving users a better operating feel.

[0029] In summary, by providing the first extension area 42 that can extend to the bottom of one of the adjacent second fixing parts 22, the second extension area 43 that can extend to the bottom of another of the adjacent second fixing parts 22, and the floating frame 3 that can be limited by the shielding area 212, different pressing positions can generate uniform feedback force, thereby improving the user's operating feel, so the purpose of the utility model can indeed be achieved.
