[0037] To explain in detail the technical content, structural features, objectives and effects of the key structure 100 of the present invention, an embodiment is given below with reference to the drawings for detailed description.
[0038] See also Figures 1 to 4The present invention key structure 100 includes a key 1, a support member 2, and a circuit board 3. The key 1 is disposed in front of the support member 2. The key 1 is disposed in front of the circuit board 3. The circuit board 3 is disposed above the support member 2. The circuit board 3 is fixed to a plastic frame (not shown). The key 1 swings left and right along the support member 2.
[0039] The button 1 comprises a pressing portion 10, a first elastic arm 11, a second elastic arm 12, and a trigger mechanism 13. The left end of the rear side of the pressing portion 10 extends rearward, then bends to the right, and then extends forward to form the first elastic arm 11. The right end of the rear side of the pressing portion 10 extends rearward and then to the left to form the second elastic arm 12. The middle portion of the rear side of the pressing portion 10 extends rearward to form the trigger mechanism 13. The trigger mechanism 13 is disposed between the first elastic arm 11 and the second elastic arm 12.
[0040] The first elastic arm 11 is provided with a first extension arm 14, a bending arm 15, a second extension arm 16, several ridges 17 and a reduction portion 18. The left end of the rear side of the pressing portion 10 extends backward to form the first extension arm 14. The rear end of the first extension arm 14 bends to the right to form the bending arm 15. The right end of the bending arm 15 extends forward to form the second extension arm 16. The outer surface of the first extension arm 14 extends outward to form several ridges 17. The extension direction of the ridges 17 is the same as that of the first extension arm 14. The ridges 17 are used to strengthen the rigidity of the first extension arm 14 to prevent the button 1 from rotating unexpectedly. The reduction portion 18 is formed at the connection between the bending arm 15 and the second extension arm 16. The thickness of the reduced portion 18 gradually decreases from the end connected to the bent arm 15 to the end connected to the second extending arm 16. The thickness of the reduced portion 18 is less than the thickness of the first extending arm 14 and the thickness of the bent arm 15. The thickness of the second extending arm 16 is also less than the thickness of the reduced portion 18. The reduced portion 18 serves to enhance the elasticity of the second extending arm 16. Therefore, the elasticity of the second extending arm 16 is greater than that of the first extending arm 14. When the pressing portion 10 of the button 1 is pressed, the compressive stress of the first elastic arm 11 is concentrated on the reduced portion 18 and the second extending arm 16.
[0041] The second elastic arm 12 is provided with a third extension arm 121 and a position-limiting hook 122. The right end of the rear side of the pressing portion 10 extends rearward to form the third extension arm 121. The corresponding mechanism of the support member 2 is fixed to the upper surface of the third extension arm 121. The rear end of the third extension arm 121 extends leftward to form the position-limiting hook 122. The position-limiting hook 122 abuts against the corresponding mechanism of the support member 2. The second elastic arm 12 is parallel to the first elastic arm 11, and the first extension arm 14 is parallel to the third extension arm 121.
[0042] The support member 2 comprises a base plate 28, two retaining walls 21, a connecting wall 22, a receiving groove 23, a boss 24, a first positioning hook 25, a protrusion 26, and a positioning portion 27. The two retaining walls 21, the connecting wall 22, the receiving groove 23, the boss 24, the first positioning hook 25, the protrusion 26, and the positioning portion 27 are all disposed on the upper surface of the base plate 28. The upper surface of the base plate 28 extends upward to form the two retaining walls 21. The two retaining walls 21 are respectively disposed on the outer side surfaces of the first extension arm 14 and the outer side surfaces of the second extension arm 16 of the first elastic arm 11. The plurality of protrusions 17 of the first extension arm 14 abut against the inner side surfaces of the retaining walls 21. The upper surface of the support member 2 extends upward to form the connecting wall 22. The two ends of the connecting wall 22 connect the rear ends of the two retaining walls 21. The connecting wall 22 is disposed on the outer side surfaces of the bent arm 15 of the first elastic arm 11. The receiving groove 23 is formed between the two retaining walls 21 and the connecting wall 22. The first elastic arm 11 is disposed in the receiving groove 23. The upper surface of the base plate 28 extends upward to form the protrusion 24. The protrusion 24 is disposed between the two retaining walls 21 and the connecting wall 22, and is located close to the inner side of the connecting wall 22. The bent arm 15 of the first elastic arm 11 is disposed between the connecting wall 22 and the protrusion 24. The first extension arm 14 and the second extension arm 16 of the first elastic arm 11 are respectively disposed between the two retaining walls 21 and the protrusion 24. The button 1 swings left and right with the protrusion 24 as a pivot.
[0043] In this embodiment, the two retaining walls 21 and the connecting wall 22 form a covering wall 20, and the first elastic arm 11 of the button 1 is disposed within the covering wall 20. The protrusion 24 is disposed within the covering wall 20, and the first elastic arm 11 of the button 1 is disposed between the covering wall 20 and the protrusion 24.
[0044] The upper surface of the left retaining wall 21 of the two retaining walls 21 extends upward to form a first positioning hook 25. The first positioning hook 25 is disposed on the upper surface of the first extension arm 14 of the first elastic arm 11 to prevent the first elastic arm 11 from separating from the covering wall 20. The inner side surface of the right retaining wall 21 of the two retaining walls 21 extends inward to form a protrusion 26. The protrusion 26 abuts against the outer side surface of the free end of the second extension arm 16 of the first elastic arm 11 to preload the second extension arm 16.
[0045] The upper surface of the base plate 28 extends upward to form the positioning portion 27. The positioning portion 27 corresponds to the second elastic arm 12 of the button 1 and is disposed inside the third extension arm 121. A second positioning hook 29 extends upward from the top surface of the positioning portion 27. The second positioning hook 29 of the positioning portion 27 is disposed on the upper surface of the third extension arm 121 of the second elastic arm 12, preventing the second elastic arm 12 from disengaging from the second positioning hook 29. The limiting hook 122 of the second elastic arm 12 abuts against the rear side of the positioning portion 27, preventing the limiting hook 122 from moving forward and disengaging from the positioning portion 27.
[0046] A switch 31 is provided on the top surface of the circuit board 3. A trigger portion 32 is provided on the front side of the switch 31. The rear end of the trigger mechanism 13 of the button 1 corresponds to the trigger portion 32. When the pressing portion 10 of the button 1 is pressed, the trigger mechanism 13 presses against the trigger portion 32, generating a signal that causes the circuit board 3 to execute instructions accordingly. In practice, the second elastic arm 12 can be replaced with a non-elastic limiting arm.
[0047] As mentioned above, the button 1 of the button structure 100 of the present invention swings left and right with the boss 24 as a pivot. The ridge 17 is used to strengthen the rigidity of the first extension arm 14 to prevent the button 1 from rotating unexpectedly. The reduction portion 18 is used to strengthen the elasticity of the second extension arm 16. When the pressing portion 10 of the button 1 is pressed, the compressive stress of the first elastic arm 11 is concentrated on the reduction portion 18 and the second extension arm 16. The bulge 26 abuts against the outer side surface of the free end of the second extension arm 16 of the first elastic arm 11 to form a pre-stress on the second extension arm 16. Therefore, the button structure 100 of the present invention has high sensitivity and is easy to operate.
