Description

Technical Field

[0001] This utility model relates to a button structure, and more particularly to a button structure that simplifies mechanical parts, simplifies assembly, and reduces costs. Background Technology

[0002] In game controllers, shoulder buttons are frequently used operation keys. These shoulder buttons are symmetrically located on both sides of the front end of the game controller. The game controller is typically operated by pressing the shoulder buttons with the index finger. The shoulder buttons generally rely on their own rebound force and structural strength to return to their original position. Due to the relatively long length of the shoulder buttons, and manufacturing and assembly tolerances between the shoulder buttons and other components of the game controller, there is a distance between the shoulder button and the electronic components when pressed. This results in a larger gap between the shoulder button contact and the electronic components, leading to a less than ideal tactile experience.

[0003] Taiwan Patent Certificate No. M668086 discloses "a button structure", including a button with a pressing part, a protrusion, and a trigger part. The pressing part has the protrusion and the trigger part at its rear end, and the trigger part is disposed on one side of the protrusion. A conductive film is disposed on the inner side of the pressing part and covers the protrusion. A circuit board is disposed behind the button, and the circuit board has a switch, with the trigger part corresponding to the switch. A metal elastic member is disposed on one side of the circuit board, one end of which is sleeved on the conductive film on the protrusion, and the other end of which is fixed to the circuit board and electrically connected to the circuit board. A bracket is disposed behind the button, and the circuit board is disposed on the bracket.

[0004] However, the existing button structure's metal elastic element design is limited by the button and the bracket. One end of the metal elastic element is sleeved on the protruding post, and the other end is fixed to the upper surface of a positioning post of the bracket. A screw is used to secure a conductive hole in the circuit board, the other end of the metal elastic element, and the positioning post of the bracket, making assembly relatively complex. Furthermore, several pivot holes of the button are fixed to several pivots of the bracket to achieve positioning, holding, and relative rotation between the bracket and the button. The internal structure of the button is relatively complex and costly.

[0034] To explain in detail the technical content, structural features, objectives and effects of the button structure 100 of this utility model, the following embodiments are provided in conjunction with the accompanying drawings.

[0035] Please see Figures 1 to 5 The button structure 100 of this utility model includes a button 1, a bracket 2, a circuit board 3, and a metal elastic member 4. The button 1 is disposed in front of the bracket 2. The circuit board 3 is disposed on the upper surface of the bracket 2. The metal elastic member 4 is disposed between the button 1 and the bracket 2. The two ends of the metal elastic member 4 are respectively fixed to the rear surface of the button 1 and the front surface of the bracket 2.

[0036] The button 1 has a pressing part 10, a latching part 11, a first protrusion 12, a second protrusion 13, and a trigger part 14. The latching part 11 is formed by extending rearward from the middle of the inner side surface of the pressing part 10. The rear end of the latching part 11 is fixed inside the front end of the bracket 2. The right end of the inner side surface of the pressing part 10 extends rearward to form the first protrusion 12. The first protrusion 12 is fixed inside the front end of the bracket 2. The left end of the inner side surface of the pressing part 10 extends rearward to form the second protrusion 13. The second protrusion 13 is formed on one side of the latching part 11. The top of the rear end of the pressing part 10 extends rearward to form the trigger part 14. The latching part 11 is formed between the second protrusion 13 and the trigger part 14.

[0037] The latching part 11 comprises a main body 15, a hollowed-out portion 16, two elastic arms 17, and two hooks 18. The main body 15 is formed by extending rearward from the middle of the inner side of the pressing part 10. The left and right ends of the rear surface of the main body 15 extend rearward to form the two elastic arms 17. The rear ends of the two elastic arms 17 extend outward to form the two hooks 18, and the hollowed-out portion 16, which penetrates the upper and lower surfaces of the rear end of the latching part 11, is formed between the two elastic arms 17. During assembly, the two elastic arms 17 and the two hooks 18 can be appropriately elastically deformed through the hollowed-out portion 16. Therefore, during assembly, the two hooks 18 have sufficient deformation space and restoring force, allowing the latching part 11 to be smoothly engaged within the bracket 2, avoiding the overall structure of the latching part 11 being too rigid to be easily assembled within the bracket 2.

[0038] Please see Figures 3 to 5 The bracket 2 is provided with a mounting portion 21, two extension portions 22, a connecting portion 23, a receiving space 24, two connecting walls 25, an opening 26, a covering portion 27, and a groove 28. The mounting portion 21 is formed by extending downward from the middle of the front end of the lower surface of the bracket 2. The snap-fit ​​portion 11 of the button 1 is assembled into the mounting portion 21.

[0039] The mounting portion 21 is provided with two extension portions 22 and a connecting portion 23. The left and right ends of the front end of the lower surface of the bracket 2 extend downwards to form two extension portions 22. The second protrusion 13 of the button 1 is aligned with the front surface of one of the extension portions 22. When the button 1 is pressed, the rear surface of the second protrusion 13 of the button 1 interferes with the front surface of one of the extension portions 22, preventing continuous pressure on the second protrusion 13 of the button 1 and thus avoiding damage to the button 1. The bottom ends of the two extension portions 22 extend towards each other to form the connecting portion 23. The two extension portions 22 and the connecting portion 23 surround to form a receiving space 24. The latching portion 11 of the button 1 is disposed within the receiving space 24.

[0040] Two connecting walls 25 are formed by extending inward from the middle of the inner sides of the two extension portions 22. The upper and lower ends of the two connecting walls 25 connect the lower surface of the bracket 2 and the upper surface of the connecting portion 23. An opening 26 is formed between the two connecting walls 25 and communicates with the receiving space 24. The two hooks 18 of the latch portion 11 of the button 1 pass through the opening 26 and are fixed to the rear surface of the two connecting walls 25 to achieve positioning and fixation of the button 1 and the bracket 2.

[0041] The lower surface of the bracket 2 extends downward to form the covering portion 27. The covering portion 27 is formed on one side of the mounting portion 21. The front surface of the covering portion 27 is recessed rearward to form the groove 28. The first protrusion 12 of the button 1 is fixed in the groove 28. When the button 1 is pressed, the rear surface of the first protrusion 12 of the button 1 interferes with the inner surface of the covering portion 27, preventing the first protrusion 12 of the button 1 from being continuously pressed backward and causing damage to the button 1.

[0042] The circuit board 3 is provided with a switch 31 and a connecting piece 32. The switch 31 is located at the front end of the circuit board 3. When the pressing part 10 of the button 1 is pressed, the trigger part 14 of the button 1 presses against the switch 31 to generate a signal, causing the circuit board 3 to execute a command according to the signal. The lower surface of the circuit board 3 is provided with the connecting piece 32 extending downward. The connecting piece 32 is fixed to the front surface of one of the connecting walls 25 of the bracket 2.

[0043] One end of the metal elastic member 4 is fixed to the front surface of the connecting piece 32 of the circuit board 3, and the other end of the metal elastic member 4 abuts against the inner side of the pressing part 10 of the button 1 and is located on the other side of the latching part 11 of the button 1. When the button 1 is pressed, the elastic force of the metal elastic member 4 eliminates the feeling of free travel between the trigger part 14 of the button 1 and the switch 31 of the circuit board 3, thereby improving the user experience.

[0044] As described above, in the button structure 100 of this utility model, the left and right ends of the rear surface of the main body 15 of the latching part 11 extend rearward to form two elastic arms 17. The rear ends of the two elastic arms 17 extend outward to form two hooks 18. During assembly, the two elastic arms 17 and the two hooks 18 can be appropriately elastically deformed through the hollowed-out part 16. The left and right ends of the front end of the lower surface of the bracket 2 extend downward to form two extensions 22. The bottom ends of the two extensions 22 extend towards each other to form the connecting part 23. The middle of the inner side surface of the two extensions 22 extends inward to form two connecting walls 25. The upper and lower ends of the two connecting walls 25 connect the lower surface of the bracket 2 and the upper surface of the connecting part 23. The opening 26 is formed between the two connecting walls 25. The two hooks 18 pass through the opening 26 and are fixed to the rear surface of the two connecting walls 25 to achieve positioning and fixation of the button 1 and the bracket 2. Therefore, the button structure 100 of this utility model can simplify the mechanical parts, simplify assembly and reduce costs.
