Similarly, when the keycap 36 is released, the elastic member 38 releases the elastic potential energy and imparts the elastic restoring force to the keycap 36 , thereby driving the keycap 36 to reset. When the keycap 36 is in the above-mentioned resetting process, the sliding ends 48 connected to the two connecting rods 42 can slide relative to the sliding groove 441 in a direction away from each other, and the side portions 421 of the two connecting rods 42 can be aligned with the corresponding pivots. The keycap 36 can be driven by the side portions 421 of the two connecting rods 42 to move away from the bottom plate 30 . In other words, when the keycap 36 is in the above-mentioned reset process, the two connecting rods 42 can work together with the lifting support mechanism 40 to evenly distribute the elastic restoring force generated by the elastic member 38 to the keycap 36, so that the keycap 36 can Smoothly move upward relative to the bottom plate 30 . In other words, the connecting rod 42 can also be used to drive the keycap 36 to approach or move away from the bottom plate 30 stably, so that the keycap 36 remains stable during the lifting process, which is beneficial to the stability of the button 34 when it is actuated.

As shown in FIGS. 6 and 7 , the buckle end plate 44 includes a buckle plate body 443 and a connecting plate body 445 , and the two ends of the connecting plate body 445 are connected to one side of the buckle plate body 443 and the edge of the bottom plate 30 respectively. .

In this embodiment, the extension plate 447 can be substantially perpendicular to the locking plate 443 , that is, the extension plate 447 can be parallel to the connecting plate 445 . In actual operation, the buckle plate body 443 , the connecting plate body 445 and the extension plate body 447 can be integrally formed by stamping. It is worth mentioning that the extension plate 447 is a structure that can be omitted, that is, the buckle end plate 44 of the present invention can only include the buckle plate 443 and the connecting plate 445 without the extension plate 447. This simplifies the structural design and manufacturing process of the buckle end plate 44 .

In addition, when the sliding end 48 connected to the connecting rod 42 is slidably buckled in the slide groove 441 on the buckle end plate 44 , the sliding end 48 can bear against the top surface 301 of the bottom plate 30 . In this way, the top surface 301 of the bottom plate 30 can work with the extension plate body 447 of the buckle end plate 44 to prevent the sliding end 48 from overturning, so that the sliding end 48 can slide stably in the chute 441, thereby stabilizing the connection. The lever 42 drives the keycap 36 to approach or move away from the bottom plate 30 smoothly. Further, the cross-sectional area of the sliding end portion 48 connected to the connecting rod 42 is smaller than the cross-sectional area of the end P of the connecting rod 42 . In this embodiment, the sliding end portion 48 can be a truncated cone structure, and its cross-sectional area decreases gradually along the direction away from the end portion P of the connecting rod 42 (as shown in FIG. 7 ).

Since the cross-sectional area of the truncated cone structure (that is, the sliding end 48) is smaller than the cross-sectional area of the end P of the connecting rod 42 and decreases gradually along the direction away from the end P of the connecting rod 42, when the truncated cone When the structure (i.e. the sliding end 48) bears against the top surface 301 of the base plate 30, the truncated conical structure (i.e. the sliding end 48) can approach the top surface 301 of the base plate 30, whereby the truncated portion of the sliding end 48 The structural design of the top cone can reduce the overall height of the connecting rod 42 when it rests on the top surface 301 of the bottom plate 30, and the side portion 421 of the connecting rod 42 is pivotally connected to the pivoting structure 46 on the keycap 36, so When the overall height of the connecting rod 42 is reduced, the keycap 36 can also be driven by the side portion 421 of the connecting rod 42 to approach the top surface 301 of the bottom plate 30 . In this way, the overall height of the key 34 can be reduced, which is beneficial to the development trend of the key 34 and the keyboard 3 towards thinning. In practice, the sliding end 48 can be machined into this frusto-conical structure by grinding.

Please refer to FIG. 8 . FIG. 8 is a schematic diagram of some components of a connecting rod 42 ′ according to another embodiment of the present invention. As shown in FIG. 8 , the main difference between the connecting rod 42 ′ and the above connecting rod 42 is that the sliding end 48 ′ connected to the end P of the connecting rod 42 ′ is substantially a D-shaped rod. That is, the sliding end 48' can be processed into a D-shaped structure by cutting, that is, the sliding end 48' can be processed by cutting, so that the sliding end 48' forms a D-shaped plane E. The rod, and further make the cross-sectional area of the D-shaped rod (ie, the sliding end 48 ′) smaller than the cross-sectional area of the end P of the connecting rod 42 ′. In this way, when the sliding end 48 ′ bears against the top surface 301 of the bottom plate 30 , the D-shaped rod with a plane E (ie, the sliding end 48 ′) can reduce the overall height of the connecting rod 42 ′, Decreasing the overall height of the keys 34 is beneficial to the trend towards thinning the keys 34 and the keyboard 3 .

Please refer to Fig. 9. Fig. 9 is a schematic diagram of some elements of another embodiment of the utility model connecting rod 42 ". As shown in Fig. 9, the main difference between the connecting rod 42 "and the above-mentioned connecting rod 42 is that the connection The sliding end 48" at the end P of the connecting rod 42" is a rod formed with two planes E1, E2, and the two planes E1, E2 are opposite to each other, that is, the sliding end 48" can be processed by cutting It is processed so that two opposite planes E1 and E2 are formed on the sliding end 48 ", and then the cross-sectional area of the bar (that is, the sliding end 48 ") is smaller than the cross-sectional area of the end P of the connecting rod 42 " . In this way, when the sliding end 48″ is abutted against the top surface 301 of the bottom plate 30, the bar (that is, the sliding end 48″) with two opposite planes E1, E2 can be used to reduce the connecting rod 42″ The overall height of the keys 34 can be lowered to facilitate the trend of the keys 34 and the keyboard 3 becoming thinner.

Compared with the prior art, the cross-sectional area of the sliding end connected to the end of the connecting rod in the utility model is smaller than the cross-sectional area of the end of the connecting rod, so when the sliding end bears against the top surface of the bottom plate, The structural design of the above-mentioned sliding end can make the sliding end approach the top surface of the bottom plate, thereby reducing the overall height of the connecting rod. In addition, the connecting rod is connected to the keycap, so the keycap can also be driven by the connecting rod to approach the top surface of the bottom plate. In this way, the overall height of the keys can be reduced, which is conducive to the development trend of keys and keyboards towards thinner.
