[0035] See also Figure 1 , Figure 1The figure is a three-dimensional schematic diagram of the appearance of a key structure of one embodiment of the present invention. The key structure 100 has a base 101, an upper cover 102, and a pressing component 103. The upper cover 102 provides external protection for the key structure 100 and covers the upper part of the base 101. The upper cover 102 has a hole (or through hole) facing upward, and the pressing component 103 extends through the through hole for the user to press and activate the key structure 100.
[0036] See also Figure 2 , Figure 2 The internal stereoscopic diagram of the key structure 100 after removing the upper cover 102 is shown. The base 101 carries the movable component 106, the feedback component 104, and the first elastic element 105. The pressing component 103 links the movable component 106, the movable component 106 is connected to the feedback component 104, and the feedback component 104 is coupled to the first elastic element 105; the movable component 106 has a first arm 1061, and the first arm 1061 and the feedback component 104 are located on opposite sides of the pressing component 103, for example, along the first direction D1 (shown in FIG. Figure 4A ) The first arm 1061 and the feedback component 104 are located on opposite sides of the pressing component 103.
[0037] See also Figure 3A , which shows Figure 2 , to more clearly illustrate the detailed structures of the pressing component 103, the movable component 106, the feedback component 104, the second elastic element 107, and the first elastic element 105. The movable component 106 also has a second arm 1062, a third arm 1063, a fourth arm 1064, and a main arm 1065. The first arm 1061 is located on a fixing groove 108 to provide fixed support for the movable component 106, and the second arm 1062 passes through the connecting hole 1031 of the pressing component 103 to drive the movable component 106 to move when the pressing component 103 is pressed. In this embodiment, the fixing groove 108 is set on the side wall 1013 of the base body 101, but the utility model is not limited thereto, and any component that can provide support for the first arm 1061 can be considered to be included in the utility model.
[0038] Please see further Figure 3B , which shows the linkage relationship between the feedback component 104 and the movable component 106 more clearly from another side angle. Figure 3BAs shown, it can be seen that the feedback component 104 has a hollow track 1042, the width of the track 1042 can preferably accommodate the cross-sectional width of the third arm 1063, and the track 1042 has three positions, namely, a first position P1, a second position P2, and a third position P3. Starting from the first position P1, the track 1042 forms an arc track in the order of the first position P1, the third position P3, and the second position P2, wherein the horizontal distance between the third position P3 and the pressing component 103 is smaller than the horizontal distance between the first position P1 or the second position P2 and the pressing component 103.
[0039] The following combination Figure 3A and Figure 3B The connection relationship of the various components of the key structure of the present invention is described. The third arm 1063 is preferably coupled to the feedback component 104 at the track 1042. The main arm 1065 is perpendicular to the first arm 1061 and extends from the first arm 1061 to the third arm 1063. In one embodiment, the main arm 105 connects the first arm 1061 and the third arm 1063, and the main arm 1065 serves as the main connecting rod of the movable component 106 from the pressing component 103 to the feedback component 104 (for example, the first direction D1). The second arm 1062 preferably extends vertically outward from the middle part of the main arm 1065. The third arm 1063 preferably extends vertically outward from the end part of the main arm 1065, and the extension direction of the second arm 1062 and the third arm 1063 is preferably in the same direction. The fourth arm 1064 is preferably located at the end portion of the main arm 1065, for example, extending downward from the end of the main arm 1065, so as to serve as a trigger portion of an actuating switch (e.g., an optical switch). In one embodiment, the actuating switch is an optical switch, and when the movable component 106 moves from the first position P1 to the second position P2, the movable component 106 triggers the optical switch. In addition, the first elastic element 105 is sleeved on the support column 1041 of the feedback component 104 to provide a restoring elastic force for the feedback component 104. The second elastic element 107 is located below the pressing component 103 to provide a restoring force for the pressing component 103 to rebound to its original position after being pressed. When an external force is applied to the pressing component 103, the pressing component 103 compresses the second elastic element 107. When the external force is released, the second elastic element 107 drives the pressing component 103 back to the position when no external force is applied. The buckle component 1011 is located on the side wall 1013 of the base 101, and is used to cooperate with the buckle hole 1021 of the upper cover 102 to provide the upper cover 102 with a function of fixing the side wall 1013. The first elastic element 105 and the second elastic element 107 are preferably provided in the form of springs. The relative position relationship of all the above components is only combined with the reference of the drawings, and the scope of the utility model is not limited thereto.
[0040] See also Figure 3C, which shows the base 101 of the key structure 1 at an elevation angle, and the optical switch 1010 includes a light emitter 1014 and a light receiver 1016 respectively disposed on opposite sides of the bottom end of the fourth arm 1064 close to the base 101. The optical switch 1010 forms an optical channel 1012 between the light emitter 1014 and the light receiver 1016. Figure 3C As the fourth arm 1064 cooperates with the operation of the pressing component 103, the light channel 1012 between the optical switch 1010 will be triggered because the bottom end of the fourth arm 1064 is located in the light channel 1012 when the third arm 1063 is located at position P2, blocking the light channel 1012. A more detailed description of the operation of the optical switch 1010 in cooperation with other components will be provided below.
[0041] See also FIG. 4A to FIG. 4C , which shows a cross-sectional schematic diagram of a key switch structure of an embodiment of the present invention, so as to illustrate the operating principle of the key switch of the embodiment of the present invention. The feedback component 104 has a track 1042, which provides a space for coupling between the feedback component 104 and the movable component 106. In this embodiment, as shown in FIG. Figure 3B As shown, the width of the track 1042 is preferably able to accommodate the cross-sectional width of the third arm 1063, and the track 1042 has a first position P1, a third position P3 and a second position P2 in sequence along the moving direction of the pressing member 103, so that the track 1042 is in an arc shape when viewed from the side, as shown in FIG. Figure 4A As shown, but the present invention is not limited thereto. When the pressing component 103 is not pressed, the movable component 106 is coupled to the feedback component 104 at the first position P1. In this state, the fourth arm 1064 of the movable component 106 is located above the optical channel 1012, and the optical signal emitted by the optical transmitter 1014 is received by the optical receiver 1016 through the optical channel 1012. Figure 4BAs shown, as the pressing component 103 is pressed, the connecting hole 1031 of the pressing component 103 drives the second arm 1062 to move downward (i.e., the movable component 106 rotates clockwise with the first arm 1061 as the axis), so that the third arm 1063 moves from the first position P1 to the second position P2. During the movement, the feedback component 104 moves in the first direction marked as D1. When the feedback component 104 moves in the first direction D1, the feedback component 104 compresses the first elastic element 105, wherein the first direction D1 is substantially perpendicular to the moving direction of the pressing component 103. The linear distance between the third position P3 in the track 1042 and the pressing component 103 (along the first direction D1) is shorter than the linear distance between the first position P1 and the second position P2 and the pressing component 103 (along the first direction D1). Therefore, the compression amount of the first elastic element 105 or the linear compression displacement of the first elastic element 105 reaches the maximum at the third position P3, that is, the first elastic element 105 has the maximum compression amount when the movable component 106 (the third arm 1063) moves to the third position P3. When the pressing component 103 continues to be pressed, the third arm 1063 is driven to continue to move from the third position P3 to the second position P2. During this period, the first elastic element 105 begins to release a part of the compression amount, so that the feedback component 104 moves in the second direction marked as D2, prompting the movable component 106 to move quickly to the second position P2, thereby generating a pressing feedback with the pressing component 103 and transmitting it to the user, providing the user with a clear paragraph feel. During the period when the pressing member 103 is pressed downward, the optical channel 1012 is blocked by the fourth arm 1064 when the third arm 1063 moves to the second position P2, so that the optical receiver 1016 does not actually receive the optical signal or the received optical signal is of low intensity, and the optical switch 1010 is triggered to generate a trigger signal. Afterwards, when the external force is released, the restoring force provided by the second elastic element 107 causes the pressing member 103 to move upward and return to the position before being pressed, and the pressing member 103 drives the movable member 106 to rotate in the counterclockwise direction, so that the movable member 106 and the feedback member 104 return from being coupled at the second position P2 to being coupled at the first position P1.
[0042] Reference again FIG. 4A to FIG. 4C When the movable component 106 moves from the first position P1 to the second position P2, the main arm 1065 and the pressing component 103 present different angles. Figure 4A In the embodiment, the main arm 1065 of the moving part 106 and the pressing part 103 present an angle less than 90 degrees (for example, the angle between the moving direction of the pressing part 103 and the extending direction of the main arm 1065), Figure 4BThe middle main arm 1065 is parallel to the horizontal axis and is at a 90-degree vertical angle with the pressing component 103. At this time, the compression amount of the first elastic element 105 reaches the maximum. When the movable component 106 rotates to make the third arm 1063 continue to move from the third position P3 to the second position P2, the main arm 1065 and the pressing component 103 present an angle greater than 90 degrees.
[0043] Furthermore, the inner side of the track 1042 of the feedback component 104, especially near the first position P1 and the second position P2, may have an elastic deformation function, for example, it may be formed of an elastic material (such as rubber) itself, or an elastic patch (similar to a rubber patch, a metal spring, etc.) may be provided. When the pressing component 103 is pressed to the bottom, the third arm 1063 may contact the second position P2 (such as the elastic patch here) to provide a buffering effect through elastic deformation, thereby reducing the impact sound of the third arm 1063 moving downward, so that in addition to transmitting the sense of pressing feedback to the pressing component 102, the third arm 1063 also has a silent effect during the pressing process. When the external force is released, the restoring force provided by the second elastic element 107 causes the pressing component 103 to move upward and return to the position before pressing, and the pressing component 103 drives the movable component 106 to rotate in the counterclockwise direction, so that the movable component 106 and the feedback component 1043 return from being coupled at the second position P2 to being coupled at the first position P1. Because the elastic deformation at the first position P1 can provide a certain buffer force, the impact sound of the third arm 1063 moving upward is reduced, and thus the third arm 1063 has a silent effect during the pressing process.
[0044] Figure 5 Fig. 7 shows a key structure of another embodiment of the present invention. Components with the same or similar functions as those described above will not be described in detail, such as the base 101, the upper cover 102, the optical switch 1010, etc.
[0045] See also Figure 5 , a three-dimensional schematic diagram of a key structure of another embodiment of the utility model is described. In this embodiment, the key structure includes a base 101, a pressing component 103, a movable component 106, and a feedback component 1043. Fig. 6A and Figure 6B Further display and explanation Figure 5 A partial decomposition diagram of .
[0046] See also Fig. 6A, the pressing component 103 links the movable component 106. The difference between the movable component 106 and the previous embodiment is that the movable component 106 may not have the fourth arm 1064, so as to trigger the key structure by other switches (such as Hall switch), but it is not limited to this. According to practical applications, by modifying the structure of the movable component, the key structure of this embodiment can also generate a trigger signal by an optical switch, which will not be repeated here. In one embodiment, the feedback component 1043 has at least one elastic element, and the at least one elastic element corresponds to the first position P1 and / or the second position P2. When the coupling position between the movable component 106 and the feedback component 1043 changes, the at least one elastic element provides a buffering force to the movable component 106. The at least one elastic element may be a metal spring. In this embodiment, the feedback component 1043 has a third elastic element 10431 and a fourth elastic element 10432. As Figure 6B As shown, Figure 3A The difference between the feedback component 1043 and the feedback component 1043 is that the track 1042 of the feedback component 1043 can be defined by an elastic sheet 10433 having a curved shape. Fig. 6A As shown, the third elastic element 10431 is in the shape of a wedge, with the tip of the wedge facing the track 1042; the fourth elastic element 10432 may be in the shape of an arc, with the C-shaped curved portion of the arc facing the track 1042. The third elastic element 10431 and the fourth elastic element 10432 are respectively disposed at both ends of the track 1042, but the present invention is not limited thereto. Figure 6B The feedback component 1043 is shown from another angle. As shown in the figure, the elastic sheet 10433 extends from the first position P1 to the second position P2. The middle section of the elastic sheet 10433 presents a curved curve at the third position P3, and preferably protrudes in a direction away from the pressing component 103, so that the track 1044 has a smaller channel width at the third position P3 than at the first position P1 or the second position P2. The third arm 1063 can move along the elastic sheet 10433 between the third elastic element 10431 and the fourth elastic element 10432.
[0047] As shown in the figure, the third elastic element 10431 and the fourth elastic element 10432 are preferably respectively disposed at the first position P1 and the second position P2 of the track 1044 to provide a buffer for the third arm 1063 of the movable component 106 to move to the first position P1 or the second position P2 relative to the track 1042, thereby reducing the impact force between the movable component 106 and the feedback component 104. For example, the third elastic element 10431 and the fourth elastic element 10432 in this embodiment may be made of sheet metal with rich elasticity, but the present invention is not limited thereto, and any buffer that can provide elasticity (such as a buffer pad) can be included in the concept of the present invention.
[0048] FIG. 7A to FIG. 7C A schematic cross-sectional view of a key structure of another embodiment of the present invention is shown, which further illustrates the present invention. Fig. 6A and Figure 6B The operating principle of the embodiment. Fig. 7A It is shown that when the pressing component 103 is not pressed, the third arm 1063 is coupled to the first position P1 of the feedback component 1043 and can contact the third elastic element 10431 . Figure 7B After the user presses the display pressing component 103, the movable component 106 is driven to rotate, so that the third arm 1063 moves downward from the contacting third elastic element 10431 (i.e., the first position P1 of the track 1042) due to the pressing action of the pressing component 103, and leaves the third elastic element 10431 and moves to the fourth elastic element 10432 (i.e., the second position P2 of the track 1042). Figure 7C It is shown that when the pressing component 103 is pressed to the bottom, the third arm 1063 contacts the fourth elastic element 10432 to provide a buffering effect by means of the elastic force of the fourth elastic element 10432. When the third arm 1063 moves from the first position P1 to the second position P2, the third arm 1063 pushes the elastic sheet 10433 at the third position P3, causing the elastic sheet 10433 to deform, thereby providing elastic forced feedback to the pressing component 103, so that the user has a sense of pressing. And because the fourth elastic element 10432 provides a certain buffering force, the impact sound of the third arm 1063 moving downward is reduced, so that the third arm 1063 not only transmits the sense of pressing feedback to the pressing component 103, but also makes the third arm 1063 silent during the pressing process. Furthermore, when the external force is released, the restoring force provided by the second elastic element 107 causes the pressing component 103 to move upward and return to the position before pressing, and the pressing component 103 drives the movable component 106 to rotate in the counterclockwise direction, so that the movable component 106 and the feedback component 1043 return from being coupled at the second position P2 to being coupled at the first position P1. Because the third elastic element 10431 provides a certain buffering force, the impact sound of the third arm 1063 moving upward is reduced, and thus the third arm 1063 has a silent effect during the pressing process.
[0049] In summary of the above embodiments of the present invention, the key structure of the present invention provides the user with clear step-feeling pressing feedback when pressing the key by means of the feedback component, and further utilizes the elastic element to reduce the impact force, thereby reducing the impact sound, while providing a silent effect.

Those skilled in the art should be aware that the embodiments of the present invention may have other modifications without departing from the spirit of the present invention, and such modifications should be included in the scope of the present invention. Therefore, the scope of the present invention should only be limited by the scope of the attached patent application.
