DETAILED DESCRIPTION

[0019] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] As Figure 1 shown:

[0021] A long key structure with uniform feel, comprising a lower cover shell 110 and an upper cover shell 111 fixed on the upper part of the lower cover shell 110 by bolts.

[0022] In this embodiment: To solve the technical problems existing in the prior art, as disclosed in the background art above, "the current long key structure method mainly has two kinds, one is a double tactile switch structure, in order to solve the problem of no effect of pressing the edge of the long key, a tactile switch 108 is usually arranged at each end of the key. This method can realize the function of edge pressing, but when the user presses the middle area, two switches may be triggered at the same time, resulting in two key sounds, thereby affecting the user experience; the other is a seesaw structure, in which there is a tactile switch 108 at each end of the key, and the middle is fixed by a rotating shaft. This method avoids the problem of simultaneous action of two switches when pressing the middle, but the middle area cannot be pressed, limiting the user's operation experience", the combination of use, this problem is obviously a real problem and is relatively difficult to solve.

[0023] Further:

[0024] As Figures 1-2 shown:

[0025] In combination with the above: the inside of the lower cover shell 110 is provided with a PCB board 109, and a tactile switch 108 is welded to the middle part of the upper surface of the PCB board 109;

[0026] The upper cover shell 111 is provided with a key cover plate 101, and the key cover plate 101 is provided with a key C, which is located at the middle part of the key cover plate 101;

[0027] The upper cover shell 111 is provided with an upper cover rotating shaft 104, and the key cover plate 101 is connected with the upper cover rotating shaft 104;

[0028] The inside of the upper cover shell 111 is provided with symmetrically arranged upper cover elastic arms 105, two groups of positioning holes are formed in each group of upper cover elastic arms 105, and the key cover plate 101 is fixedly provided with key fixing columns 102 which can be inserted into the positioning holes;

[0029] The key cover plate 101 is provided with a key buckle 103, and the upper cover shell 111 is provided with a clamping groove corresponding to the key buckle 103, the key cover plate 101 is installed on the upper cover shell 111 through the key buckle 103, and the key cover plate 101 can be vertically pressed on the upper cover shell 111;

[0030] The key fixing column 102 on the key cover plate 101 is tightly matched with the positioning hole formed in the upper cover elastic arm 105;

[0031] The lower cover housing 110 has symmetrically arranged limiting protrusions 107 fixed inside. The PCB board 109 has limiting holes 106 that are adapted to the limiting protrusions 107. When the PCB board 109 is locked onto the limiting protrusions 107 on the lower cover housing 110 through the limiting holes 106, it is used to quickly position and install the PCB board 109 and the lower cover housing 110. The button cover 101 is located in the middle of the two sets of upper cover elastic arms 105 and is in a suspended state.

[0032] In this implementation scheme: The long button structure with a uniform tactile feel, during use, because button C is provided on the button cover 101, such as... Figure 1 Buttons A and B, as shown, adopt a rocker structure in a conventional design. Since the button cover 101 is connected to the upper cover pivot 104 on the upper cover housing 111, the two sides of the button cover 101 can be pressed in a rocker manner. Button C is located in the middle of the button cover 101. The button cover 101 is fastened to the slot of the upper cover housing 111 by the button buckle 103. The button cover 101 can be pressed vertically up and down on the upper cover housing 111, so that button C can be pressed at any angle. Moreover, the pressing feel of each corner is uniform and is similar to the pressing feel of buttons A and B.

[0033] When the button cover 101 is long, a tactile switch 108 is set in the middle of the PCB board 109 to ensure that the button function can be triggered at any angle on the button cover 101 and that the force is relatively even, reducing the situation of excessive local pressure.

[0034] like Figure 2 As shown, whenever the button cover 101 is pressed at point A, the button fixing post 102 of the button cover 101 is tightly fitted with the positioning hole of the upper cover elastic arm 105 at position AC, preventing the button cover 101 from tilting and pressing. Points A and C can only be pressed down together in parallel, forming an elastic balance. This allows the button cover 101 to be pressed down in parallel, triggering the tactile switch 108 even when pressing the corner. Whether point A or point C is pressed, the effect is that points AC are pressed down in parallel, ensuring a consistent button feel. The same principle applies when pressing other corners. This operation eliminates the need for two tactile switches 108 at both ends of the button, requiring only one tactile switch 108 in the middle. This prevents the sound of two buttons acting simultaneously when the middle is pressed, and allows the button to function from any position, with a consistent feel as when pressed in the middle. This improves the usability of the structure and meets practical usage needs.

[0035] It should be noted that the hand feeling of the key is adjusted by adjusting the wall thickness, length L and width W of the upper cover elastic arm 105, and it is suggested that L=20, the width is 2.5 times the wall thickness, and the specific use can be used according to the actual situation.

[0036] The working principle and use process of the utility model: the long key structure with uniform hand feeling, when using, because the key cover plate 101 is provided with the key C, the key A and the key B adopt the flip plate structure in the conventional structure, because the key cover plate 101 is connected with the upper cover shaft 104 on the upper cover shell 111, thereby the flip plate pressing mode on both sides of the key cover plate 101 can be realized, and the key C is located at the middle position of the key cover plate 101, the key cover plate 101 is buckled in the clamping groove of the upper cover shell 111 through the key buckle 103, and the key cover plate 101 can be vertically pressed up and down on the upper cover shell 111, so that the key C can be pressed at any angle, and the pressing hand feeling of each corner is uniform, and the pressing process touch of the key A and the key B is equivalent;And for the long key cover plate 101, the light touch switch 108 is arranged at the middle position of the PCB 109, so as to ensure that any angle of the key cover plate 101 can trigger the key function, and the stress is relatively uniform, and the local excessive pressure condition is reduced;Whenever the key cover plate 101 is pressed at A, because the key fixing column 102 of the key cover plate 101 is tightly matched with the positioning hole of the upper cover elastic arm 105 at the AC position, the key cover plate 101 cannot be inclined and pressed, and only A and C points can be pressed together, forming an elastic balance, so that the key cover plate 101 is pressed horizontally to reach the pressing edge corner, and the light touch switch 108 function can be triggered, whether the A point is pressed or the C point is pressed, the effect is that the AC point is pressed horizontally, so that the hand feeling of the key can be ensured to be consistent, through the operation, only one light touch switch 108 is needed in the middle, so that the sound of two keys acting at the same time when pressing in the middle does not occur, and the key function can be realized at any position of the whole key, and the hand feeling is consistent with the hand feeling when pressing in the middle, the use effect of the structure is improved, and the actual use requirement is met.
