Detailed Description
Fig. 1 is a schematic diagram of a key structure according to an embodiment of the invention. Fig. 2 and 3 are exploded views of the key structure of fig. 1 at two different viewing angles. Fig. 4 is a schematic cross-sectional view of the key structure of fig. 1. Referring to fig. 1 to 4, in the present embodiment, the key structure 100 can be applied to a keyboard for inputting signals to a physical operation interface of a desktop computer, a notebook computer or other electronic devices.
Specifically, the key structure 100 includes a base plate 110, a key cap 120, a scissor 130, a spring 140, a positioning seat 150, a first cover 160 and a second cover 170, wherein the key cap 120 is disposed above the base plate 110, and the scissor 130, the spring 140, the positioning seat 150, the first cover 160 and the second cover 170 are located between the base plate 110 and the key cap 120. For example, the scissor leg 130 includes two movable legs, each of which may be a rectangular frame surrounding the spring 140, the positioning seat 150, the first cover 160, and the second cover 170.
Referring to fig. 2 to 4, the scissors 130 abuts against the bottom plate 110 and the keycap 120 to maintain stability of the keycap 120 when moving up and down relative to the bottom plate 110. On the other hand, the spring 140 abuts against the keycap 120 and the base plate 110, wherein the spring 140 can be a compression spring, and the cooperation of the scissor legs 130 and the spring 140 can support the keycap 120. When the key cap 120 is pressed to move toward the base plate 110, the scissor legs 130 descend and the springs 140 are compressed. The compressed spring 140 generates a reaction force to the key cap 120 to prevent the key cap 120 from instantaneously dropping. After the pressing force applied to the key cap 120 is removed, the scissor legs 130 and the key cap 120 are lifted by the elastic force of the spring 140. Therefore, the elastic force of the spring 140 can not only drive the scissor legs 130 to reset with the keycap 120, but also provide good operation handfeel (tactile sensation).
The positioning seat 150 is connected to the key cap 120, wherein the key cap 120 has a pressing surface 121 for being pressed by a user and an inner surface 122 facing the base plate 110, and the positioning seat 150 is connected to the inner surface 122. The positioning seat 150 may be integrally formed on the inner surface 122 of the key cap 120, or locked and fixed on the inner surface 122 of the key cap 120, glued and fixed on the inner surface 122 of the key cap 120, or clamped on the inner surface 122 of the key cap 120. The positioning seat 150 has a positioning groove 151 and exposes the inner surface 122 of the key cap 120. A portion of the spring 140 is positioned within the detent 151 and abuts the inner surface 122 of the key cap 120.
Referring to fig. 2 to 4, in the present embodiment, the first cover 160 is connected to the positioning seat 150, wherein the first cover 160 may be a positioning ring and is sleeved and fixed on the positioning seat 150. The first cover 160 has a through hole 161 overlapping the positioning groove 151, wherein the spring 140 extends from the positioning groove 151 toward the base plate 110 and passes through the through hole 161. On the other hand, the second cover 170 is slidably connected to the first cover 160 and the positioning seat 150, and the first cover 160 is sleeved on the second cover 170 to prevent the second cover 170 from being separated from the positioning seat 150.
Further, the second cover 170 passes through the through hole 161 and abuts against the bottom plate 110, and the spring 140 extending toward the bottom plate 110 is inserted into the second cover 170 and abuts against the second cover 170. That is, the other portion of the spring 140 abuts the second cover 170 and is covered by the second cover 170. Further, the spring 140 includes a first end 141 and a second end 142 opposite to the first end 141, wherein the first end 141 is inserted into the positioning groove 151 and abuts against the inner surface 122 of the key cap 120, and the second end 142 is inserted into and abuts against the second cover 170 to abut against the bottom plate 110 through the second cover 170.
In the present embodiment, the sliding amount of the second cover 170 is substantially determined by the depth of the positioning groove 151, and the compression amount of the spring 140 is substantially determined by the sliding amount of the second cover 170. On the other hand, the key cap 120 includes a positioning protrusion 123 protruding from the inner surface 122, wherein the positioning protrusion 123 is located in the positioning groove 151, and the first end 141 of the spring 140 is sleeved on the positioning protrusion 123, so as to position the spring 140 on the inner surface 122 of the key cap 120, and prevent the spring 140 from sliding relative to the key cap 120 arbitrarily.
When the user presses the key cap 120, the positioning seat 150 and the first cover 160 move toward the bottom plate 110, and the second cover 170 slides relative to the first cover 160 and the positioning seat 150. The second cover 170 moves into the positioning groove 151 via the through hole 161 and moves close to the inner surface 122 of the key cap 120 so that the spring 140 is compressed. As the distance between the second cover 170 and the inner surface 122 of the key cap 120 is reduced, the greater the amount of compression of the spring 140. Until the second cover 170 interferes with the inner surface 122 of the key cap 120, the second cover 170 stops sliding relative to the first cover 160 and the positioning seat 150, and the spring 140 has the greatest amount of compression.
Since the spring 140 is covered and protected by the positioning seat 150, the first cover 160 and the second cover 170, the spring 140 is not easily damaged or damaged. On the other hand, the cooperation of the positioning seat 150, the first cover 160 and the second cover 170 can guide the compression and recovery directions of the spring 140 to prevent the keycap 120 moving up and down relative to the base plate 110 from deflecting, so as to improve the stability of the key structure 100 when a user operates the key structure.
Referring to fig. 2 to 4, in the present embodiment, the second cover 170 passes through the through hole 161, wherein the second cover 170 includes a side protrusion 171, and the side protrusion 171 is slidably disposed in the positioning slot 151. The first cover 160 is sleeved and fixed on the positioning seat 150, and the outer diameter of the side protruding portion 171 is larger than the inner diameter of the through hole 161. When the key cap 120 moves away from the bottom plate 110, the side protrusion 171 can have a limiting effect to prevent the second cover 170 from being separated from the positioning seat 150.
In detail, the first cover 160 includes a limiting portion 162 away from the inner surface 122 of the key cap 120, and the limiting portion 162 surrounds the through hole 161. In the orthographic projection direction PD perpendicular to the inner surface 122 of the key cap 120, an orthographic projection of the stopper 162 on the inner surface 122 of the key cap 120 falls within the positioning groove 151. That is, the limiting portion 162 of the first cover 160 is located on the sliding path of the second cover 170, so as to have a limiting effect on the side protruding portion 171 of the second cover 170. On the other hand, the first cover 160 further includes a plurality of hook portions 163 surrounding the limiting portion 162, and the hook portions 163 are engaged with the positioning seat 150 and are located outside the positioning groove 151.
When the user presses the key cap 120, the positioning seat 150 and the first cover 160 move toward the bottom plate 110, and the side protrusions 171 of the second cover 170 slide toward the inner surface 122 of the key cap 120 until the side protrusions 171 of the second cover 170 interfere with the inner surface 122 of the key cap 120, and the second cover 170 stops sliding relative to the first cover 160 and the positioning seat 150. After the pressing force applied to the key cap 120 is removed, the key cap 120, the positioning seat 150 and the first cover 160 are driven to move away from the bottom plate 110 by the elastic force of the spring 140 until the side protrusion 171 of the second cover 170 and the limiting portion 162 of the first cover 160 interfere with each other, and the key cap 120 stops moving away from the bottom plate 110. Accordingly, the side protrusions 171 of the second cover 170 are restricted from sliding between the inner surface 122 of the key cap 120 and the stopper 162 of the first cover 160.
Fig. 5 is a schematic diagram of a key structure according to another embodiment of the present invention. Fig. 6 and 7 are exploded views of the key structure of fig. 5 at two different viewing angles. Fig. 8 is a schematic cross-sectional view of the key structure of fig. 5. Referring to fig. 5 to 8, the key structure 100A of the present embodiment is substantially similar to the key structure 100 of the previous embodiment, and the main difference between the two is that: the design of positioning seat, first cover body and second cover body.
In the present embodiment, the key cap 120a includes a first engaging portion 124 facing the base plate 110, and the positioning seat 150a includes a second engaging portion 152 located outside the positioning groove 151. The first engaging portion 124 and the second engaging portion 152 may be a combination of a slot and a hook, and the second engaging portion 152 is engaged with the first engaging portion 124, so that the positioning seat 150a is fixed on the inner surface 122 of the key cap 120 a.
The positioning seat 150a is sleeved with the first cover 160a, and the first cover 160a is sleeved with the second cover 170a. Further, the first cover 160a is slidably connected to the positioning seat 150a, and the second cover 170a is slidably connected to the first cover 160a. On the other hand, the spring 140 is inserted into the second cover 170a from the positioning slot 151 of the positioning seat 150a through the first cover 160a, and the compression amount of the spring 140 is substantially determined by the sliding amount of the second cover 170 and the sliding amount of the first cover 160a.
Referring to fig. 6 to 8, when the user presses the key cap 120a, the positioning seat 150a and the first cover 160a move toward the base plate 110, and the second cover 170a slides relative to the first cover 160a. The second cover 170a is moved into the first cover 160a through the through hole 161 so that the spring 140 is compressed until the first cover 160a is brought into structural interference with the base plate 110, and the second cover 170a stops sliding. Thereafter, the first cover 160a slides relative to the positioning seat 150a and moves into the positioning groove 151, and the spring 140 is continuously compressed until the first cover 160a and the inner surface 122 of the key cap 120a interfere with each other, and the first cover 160a stops sliding. At this time, the second cover 170a may be completely moved into the first cover 160a.
The cooperation of the spring 140, the positioning seat 150a, the first cover 160a and the second cover 170a can generate a sectional pressing stroke for feedback to the user of sectional operation feeling.
In the present embodiment, the positioning seat 150a includes a first limiting portion 153 away from the inner surface 122 of the key cap 120a, and in the orthographic projection direction PD perpendicular to the inner surface 122 of the key cap 120a, an orthographic projection of the first limiting portion 153 on the inner surface 122 of the key cap 120a falls into the positioning groove 151. On the other hand, the first cover 160a includes a first side protrusion 164, and the first side protrusion 164 is slidably disposed in the positioning groove 151. That is, the first limiting portion 153 of the positioning seat 150a is located on the sliding path of the first side protrusion 164 of the first cover 160a.
The first cover 160a further includes a second spacing portion 165 opposite the first side protrusion 164, wherein the second spacing portion 165 is distal from the inner surface 122 of the key cap 120a and surrounds the perforation 161. In the orthographic projection direction PD perpendicular to the inner surface 122 of the key cap 120a, an orthographic projection of the second stopper 165 on the inner surface 122 of the key cap 120a falls within the positioning groove 151. On the other hand, the second cover 170a passes through the through hole 161, wherein the second cover 170a includes a second side protrusion 172, and the second side protrusion 172 is slidably disposed in the first cover 160a. That is, the second stopper 165 of the first cover 160a is located on the sliding path of the second side protrusion 172 of the second cover 170a.
When the key cap 120a moves away from the bottom plate 110, the first limiting portion 153 of the positioning seat 150a can have a limiting effect on the first side protrusion 164 of the first cover 160a, so as to prevent the first cover 160a from separating from the positioning seat 150 a. On the other hand, the second limiting portion 165 of the first cover 160a can limit the second side protrusion 172 of the second cover 170a to prevent the second cover 170a from being separated from the first cover 160a
When the user presses the key cap 120a, the positioning seat 150a and the first cover 160a move toward the bottom plate 110, and the second side protrusion 172 of the second cover 170 slides toward the inner surface 122 of the key cap 120a until the first cover 160a and the bottom plate 110 interfere with each other, and the second cover 170a stops sliding. Thereafter, the first side protrusion 164 of the first cover 160a slides toward the inner surface 122 of the key cap 120a until the first side protrusion 164 of the first cover 160a interferes with the inner surface 122 of the key cap 120a, and the first cover 160a stops sliding. At this time, the second side protrusion 172 of the second cover 170 moves to a side of the first cover 160a near the first side protrusion 164, and generates structural interference with the inner surface 122 of the key cap 120 a.
After the pressing force applied to the key cap 120a is removed, the spring 140 drives the key cap 120a and the positioning seat 150a to move away from the bottom plate 110 until the first side protrusion 164 of the first cover 160a and the first limiting portion 153 of the positioning seat 150a interfere with each other, and the second side protrusion 172 of the second cover 170 and the second limiting portion 165 of the first cover 160a interfere with each other, so that the key cap 120a stops moving away from the bottom plate 110. Accordingly, the first side protrusion 164 of the first cover 160a is restricted from sliding between the inner surface 122 of the key cap 120a and the first stopper 153 of the positioning seat 150a, and the second side protrusion 172 of the second cover 170 is restricted from sliding between the inner surface 122 of the key cap 120a and the second stopper 165 of the first cover 160a.
In summary, in the key structure of the present invention, two ends of the spring are respectively inserted into the positioning seat and the second cover, and the spring passes through the first cover. Accordingly, the spring protected by the positioning seat, the first cover body and the second cover body is not easy to damage or damage. On the other hand, in one embodiment thereof, the second cover has a degree of freedom of movement that slides relative to the positioning seat and the first cover, and in another embodiment, the second cover has a degree of freedom of movement that slides relative to the first cover, and the first cover has a degree of freedom of movement that slides relative to the positioning seat. Accordingly, the matching of the positioning seat, the first cover body and the second cover body can be used for guiding the compression and restoration directions of the springs so as to prevent the keycaps moving up and down relative to the bottom plate from deflecting, and further improve the stability of a user in operating the key structure.
Although the invention has been described with reference to the above embodiments, it should be understood that the invention is not limited thereto, but rather may be modified or altered somewhat by persons skilled in the art without departing from the spirit and scope of the invention.
