Description

Technical Field

[0001] This utility model relates to a button structure, and more particularly to a button structure for use in game controllers that can improve the feel of use, stabilize assembly, and reduce costs. Background Technology

[0002] The D-pad is a standard component in game controllers, and most game controllers have it. The D-pad includes four buttons with different functions, used for movement in four directions: up, down, left, and right. The bottom of the D-pad contacts a metal button on a circuit board to improve tactile feedback.

[0003] Chinese Patent Publication No. 111886057 discloses a "control panel assembly for an input device," comprising a bracket with a support member having a supporting surface; a button cap configured to pivot relative to the bracket, the button cap including a peripheral lip and a pivoting member configured to abut against the supporting surface of the support member; and a return mechanism configured to bias the button cap toward the bracket. The return mechanism includes: a hub portion at least partially positioned between the button cap and the bracket; and at least a first spring having a fixed end connected to the hub portion and a free end configured to deflect relative to the fixed end, the free end being coupled to a first portion of the peripheral lip of the button cap.

[0004] The aforementioned game controller uses a cross-shaped button combined with a metal plate to enhance the tactile feedback. However, gaps can easily form between the cross-shaped button and the metal plate, affecting the tactile feedback, and the metal plate is also expensive to manufacture. Furthermore, the metal buttons on the circuit boards of existing game controllers have poor rebound properties.

[0005] Therefore, it is necessary to provide a button structure that can improve the user experience, stabilize assembly, and reduce costs. Summary of the Invention

[0051] 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.

[0052] Please see Figure 1 and Figure 2 The button structure 100 of this utility model includes a button 1, a housing 2, a support member 3, and a circuit board 4. The button 1 is disposed on the upper surface of the circuit board 4. The housing 2 is disposed on the upper surface of the circuit board 4 and covers the button 1. The support member 3 is disposed inside the button 1, and a portion of the support member 3 passes through the circuit board 4, and the support member 3 is fixed to the circuit board 4.

[0053] Please see Figures 3 to 5 The button 1 has a top wall 11, an outer side wall 12, an inner side wall 13, a cross key 14, several protrusions 15, several spring arms 16, several connecting parts 17, and a protruding post 18. The cross key 14 is located on the upper surface of the top wall 11, and the protruding post 18 extends downward from the middle of the lower surface of the top wall 11. The protruding post 18 is disposed in the corresponding mechanism of the support member 3. The cross key 14 has four pressing areas in four directions.

[0054] The bottom surface of the outer sidewall 12 extends outward to form several protrusions 15. These protrusions 15 are evenly distributed radially on the outer sidewall 12 of the button 1 and are located within the corresponding mechanism of the housing 2. In this embodiment, there are four protrusions 15. Each protrusion 15 corresponds to the cross key 14. Each protrusion 15 corresponds to a metal button 41 on the circuit board 4. One side of each protrusion 15 extends radially along the button 1 and obliquely upwards to form a spring arm 16. The spring arm 16 extends around the button 1 and provides a pressing feel to the user. In this embodiment, the protrusion 15 is closer to the circuit board 4 than the spring arm 16.

[0055] The spring arm 16 has a first arcuate portion 161, a bent portion 162, and a second arcuate portion 163. The first arcuate portion 161 is formed by one side of the protrusion 15 extending radially and obliquely upward. One end of the first arcuate portion 161 bends outward and then inward to form the bent portion 162. The bent portion 162 is disposed in the corresponding mechanism of the housing 2. The bent portion 162 is used to reduce the risk of plastic deformation and breakage of the spring arm 16, thereby increasing the service life of the spring arm 16. One end of the bent portion 162 extends radially and obliquely upward to form the second arcuate portion 163. In this embodiment, the height of the second arcuate portion 163 is higher than the height of the first arcuate portion 161. The second arcuate portion 163 abuts against the corresponding mechanism of the housing 2.

[0056] When the cross key 14 is pressed in one direction, the corresponding protrusion 15, the first arc-shaped portion 161, the bent portion 162, and the second arc-shaped portion 163 move downwards. At the same time, the protrusion 15, the first arc-shaped portion 161, and the bent portion 162 corresponding to the opposite direction move upwards, and the second arc-shaped portion 163 corresponding to the opposite direction abuts against the corresponding mechanism of the housing 2. Therefore, the button structure 100 of this utility model has a good tactile feel.

[0057] The inner sidewall 13 is provided with a plurality of connecting portions 17. The inner sidewall 13 of the button 1 extends inward and downward to form a plurality of connecting portions 17, which are evenly distributed radially on the inner sidewall 13 of the button 1. In this embodiment, there are four connecting portions 17. The plurality of connecting portions 17 correspond to the four directions of the cross key 14, and are connected to the lower part of the cross key 14 in the four directions. The plurality of connecting portions 17 correspond to a plurality of protrusions 15, and the bottom end of the outer side of the plurality of connecting portions 17 connects to the inner side of the plurality of protrusions 15. The top end of the plurality of connecting portions 17 connects to the inner side of the cross key 14 in the four directions. The bottom end of the plurality of connecting portions 17 corresponds to the metal button 41 of the circuit board 4. When the cross key 14 is pressed in one direction, the bottom end of the corresponding connecting part 17 presses down on the metal button 41 of the circuit board 4; when the cross key 14 is released, the connecting part 17 moves upward by the elastic restoring force of the spring arm 16, causing the connecting part 17 to return to its original position. Consequently, the metal button 41 of the circuit board 4 also springs back to its original position.

[0058] Please see Figure 3 and Figure 6The housing 2 is provided with a top wall 21, a side wall 22, several first baffles 23, several second baffles 24, several first receiving grooves 25, several second receiving grooves 26, and several stop blocks 27. The lower surface of the top wall 21 extends downward to form several stop blocks 27. The second arcuate portion 163 of the spring arm 16 of the button 1 abuts against the lower end of the stop block 27.

[0059] The housing sidewall 22 is connected to the outer periphery of the housing top wall 21. The housing sidewall 22 extends downward to form a plurality of first baffles 23 and a plurality of second baffles 24. The plurality of first baffles 23 correspond to the first arcuate portion 161 of the spring arm 16 of the button 1, and the plurality of first arcuate portions 161 are disposed on the inner side of the plurality of first baffles 23. The plurality of second baffles 24 correspond to the second arcuate portion 163 of the spring arm 16 of the button 1, and the plurality of second arcuate portions 163 are disposed on the inner side of the plurality of second baffles 24. The plurality of second baffles 24 correspond to a plurality of stop blocks 27, and the plurality of stop blocks 27 are connected to the inner side of the plurality of second baffles 24.

[0060] In this embodiment, a plurality of first baffles 23, a plurality of second baffles 24, a plurality of first receiving grooves 25, and a plurality of second receiving grooves 26 constitute four stop portions 28. Each stop portion has one first baffle 23, one second baffle 24, one first receiving groove 25, and one second receiving groove 26. The four stop portions 28 correspond to the four protrusions 15 and the spring arms 16 connected to the protrusions 15, respectively. A first receiving groove 25 is formed between the first baffle 23 and the second baffle 24 of each stop portion 28. A second receiving groove 26 is formed between the first baffle 23 of each stop portion 28 and the second baffle 24 of the adjacent stop portion 28.

[0061] A plurality of first receiving slots 25 are formed between a plurality of first baffles 23 and a plurality of second baffles 24. The plurality of first receiving slots 25 correspond to the bent portions 162 of the spring arm 16 of the button 1, and the plurality of bent portions 162 are disposed within the plurality of first receiving slots 25. A plurality of second receiving slots 26 are formed between a plurality of first baffles 23 and a plurality of second baffles 24. The plurality of second receiving slots 26 correspond to the protrusions 15 of the button 1, and the plurality of protrusions 15 are disposed within the plurality of second receiving slots 26. The plurality of first baffles 23, the plurality of second baffles 24, the plurality of first receiving slots 25 and the plurality of second receiving slots 26 constitute the housing sidewall 22.

[0062] When the cross key 14 of the button 1 is pressed in one direction, the corresponding protrusion 15, the first arc-shaped portion 161, the bent portion 162, and the second arc-shaped portion 163 move downwards. At the same time, the protrusion 15, the first arc-shaped portion 161, and the bent portion 162 corresponding to the opposite direction move upwards, and the second arc-shaped portion 163 corresponding to the opposite direction abuts against the lower end of the stop block 27. Therefore, the button structure 100 of this utility model has a good tactile feel.

[0063] Please see Figures 7 to 10 The support member 3 comprises a main body 31, a fixing post 32, two side arms 33, and a positioning groove 34. The main body 31 is disposed on the upper surface of the circuit board 4. The fixing post 32 extends downward from the middle of the main body 31, extending beyond the lower surface of the main body 31, penetrating the circuit board 4 and extending beyond its lower surface. The two opposite sides of the main body 31 extend outward to form two side arms 33, which are disposed on the upper surface of the circuit board 4. During assembly, the two side arms 33 deform upward to prevent them from abrading the circuit board 4. The positioning groove 34 is recessed downward from the middle of the top surface of the main body 31, corresponding to the protrusion 18 of the button 1, which is disposed within the positioning groove 34.

[0064] The main body 31 has a top 310, two side walls 311, two connecting walls 312, two openings 313, and two reinforcing ribs 314. In this embodiment, the main body 31 is a hollow column, and the top 310 is hexagonal. However, this is not a limitation in specific implementations. In this embodiment, the two opposite sides of the top 310 extend downward to form the two side walls 311. The middle of the outer surfaces of the two side walls 311 extends outward to form two side arms 33. Two connecting walls 312 are provided between the two side walls 311, connecting the two side walls 311. The main body 31 has two openings 313 penetrating the inner and outer surfaces of the two connecting walls 312, and the two openings 313 penetrate the bottom surface of the main body 31. The two openings 313 are used to increase the elasticity of the support member 3. The inner surfaces of the two sidewalls 311 extend inward to form two reinforcing ribs 314, which are connected to the fixed post 32. The two reinforcing ribs 314 correspond to the two side arms 33. The two reinforcing ribs 314 are used to strengthen the structural strength of the support member 3.

[0065] The fixing post 32 is provided with a fixing part 321, two first extensions 322, two second extensions 323, several grooves 324, several protrusions 325, and two hooks 326. The fixing part 321 is formed by extending downward from the middle of the lower surface of the top 310 of the main body 31. The fixing part 321 is hollow columnar. The lower surface of the fixing part 321 extends downward to form two first extensions 322 and two second extensions 323.

[0066] The two first extensions 322 are parallel to each other, and the two second extensions 323 are parallel to each other. A groove 324 is formed between each first extension 322 and each second extension 323. Several grooves 324 provide clearance space for the two first extensions 322 and the two second extensions 323 during elastic deformation, preventing the fixing post 32 from abrading the circuit board 4. Several protrusions 325 extend outward from the middle of the outer surface of the two first extensions 322, and several protrusions 325 extend outward from the middle of the outer surface of the two second extensions 323. Several protrusions 325 of the two second extensions 323 are connected to the reinforcing ribs 314 of the main body 31. The several protrusions 325 of the two first extensions 322 and the several protrusions 325 of the two second extensions 323 are used to increase the elasticity of the support member 3. Two hooks 326 extend outward from the bottom of the outer surface of the two first extensions 322. The protrusions 325 of the two first extensions 322 are connected to the two hooks 326. The two hooks 326 are disposed on the lower surface of the circuit board 4.

[0067] Each of the side arms 33 is provided with an extension arm 331, a bending arm 332, a fixed end 333, and a positioning protrusion 334. The extension arm 331 is formed by extending horizontally outward from the middle of the outer side surface of the side wall 311 of the main body 31. The outer end of the extension arm 331 is bent downward to form the bending arm 332. The lower end of the bending arm 332 extends horizontally outward to form the fixed end 333. The fixed end 333 is fixed to the upper surface of the circuit board 4. The lower surface of the fixed end 333 extends downward to form the positioning protrusion 334, which is fixed to the corresponding mechanism of the circuit board 4 to achieve positioning and fixation of the support member 3 and the circuit board 4.

The circuit board 4 is fixed between the two side walls 311, the two side arms 33, and the two hooks 326 of the main body 31 to achieve positioning and fixation between the circuit board 4 and the support member 3, preventing the circuit board 4 from shaking. During assembly, the two hooks 326 deform outward after passing through the through hole 42 to prevent the two hooks 326 from abrading the circuit board 4.

[0071] As described above, the spring arm 16 of the button structure 100 of this utility model is used to provide a pressing feel for the user. One side of the spring arm 16 extends radially and obliquely upward to form the first arc-shaped portion 161. One end of the first arc-shaped portion 161 bends outward and then inward to form the bent portion 162. The bent portion 162 is used to reduce the plastic deformation and breakage risk of the spring arm 16 and increase the service life of the spring arm 16. One end of the bent portion 162 extends radially and obliquely upward to form the second arc-shaped portion 163. When the cross key 14 of the button 1 is pressed in one direction, the corresponding protrusion 15, the first arc-shaped portion 161, the bent portion 162 and the second arc-shaped portion 163 move downward.
