Description

Technical Field

[0001] This application relates to the field of electronic technology, and in particular to a button structure and a gaming device. Background Technology

[0002] Button structures are widely used in consumer gaming devices. When the knob of a button structure rotates relative to the housing, the knob drives the encoder to elastically twist. When the force on the knob is removed, the twisted encoder releases energy and returns to its initial state, which in turn causes the encoder to move the knob to its initial position. However, with traditional button structures, it is difficult for the knob and encoder to move accurately to their initial positions, thus affecting the reliability of the button structure's operation. Utility Model Content

[0003] One of the technical problems addressed by this application is how to improve the reliability of the button structure.

[0009] In one embodiment,

[0010] The rotating unit includes two first inner wall surfaces defining the boundary of the first groove portion on the side near the rotating mating member.

From one end of the second inner wall surface near the bottom of the second groove to one end near the top of the second protrusion, the rate of change of the distance between the second inner wall surface and the base gradually decreases, remains constant, or increases first and then decreases.

[0012] In one embodiment, the rotating unit further includes a first bottom surface and a first top surface on the side near the rotating mating member. The first bottom surface is connected between the ends of the two first inner wall surfaces that define the same first groove boundary near the bottom of the first groove; the first top surface is connected between the ends of the two first inner wall surfaces that define the boundaries of two adjacent first grooves near the top of the first protrusion.

[0013] The rotating fitting component also includes a second bottom surface and a second top surface on the side near the rotating unit. The second bottom surface is connected between the ends of the two second inner wall surfaces that define the boundary of the same second groove near the bottom of the second groove; the second top surface is connected between the ends of the two second inner wall surfaces that define the boundaries of two adjacent second grooves near the top of the second protrusion.

[0014] The first bottom surface, the first top surface, the second bottom surface, and the second top surface are all parallel to the surface on which the base is located.

[0015] In one embodiment, an elastic element is also included, which abuts between the button body and the rotating engagement member.

[0016] In one embodiment, the device further includes a housing and a fixing base, the fixing base being disposed within the housing, the rotating fitting being slidably connected to the fixing base, and the rotating unit being rotatably connected to the housing.

[0017] In one embodiment, the rotating fitting includes a sliding sleeve and a limiting protrusion. The sliding sleeve abuts against the rotating unit, and the limiting protrusion protrudes from the outer side of the sliding sleeve. The fixed base has a sliding cavity, and a limiting groove communicating with the sliding cavity is recessed on the inner side of the sliding cavity. The sliding sleeve slides with the sliding cavity, and the limiting protrusion slides with the limiting groove.

[0018] In one embodiment, the elastic element is at least partially housed within the sliding cavity.

[0019] In one embodiment, the rotating unit includes a rotating component and a pressing component. The pressing component is fixedly connected to the button body, and the pressing component is slidably connected to the rotating component along the axial direction of the rotating unit. The rotating component can drive the pressing component to rotate.

[0020] In one embodiment, the rotating component is slidably sleeved outside the pressing component, and the pressing component abuts against the rotating mating component; the rotating component includes a protruding strip on the inner sidewall of the rotating component, and a guide groove is recessed on the outer sidewall of the pressing component, the guide groove and the protruding strip are slidably engaged, and in the initial position of the rotating mechanism, the shape of the protruding strip matches the shape of the guide groove.

[0023] A gaming device comprising the button structure described in any one of the above descriptions.

[0024] One technical effect of one embodiment of this application is that during operation, when the rotating unit is rotated, it generates torque on the key body, causing the key body to twist. The key body detects angular displacement based on the torsional displacement. When the rotational force applied to the rotating unit is removed, the torque on the key body is removed, allowing the key body to return to the tolerance range allowed by the ideal initial state under the action of elastic force. This also allows the key body to drive the rotating unit back to the tolerance range allowed by the ideal initial position. Since the distances from the key body to the two different areas of the periphery of the rotating unit near the rotating mating part are unequal, the periphery of the rotating unit near the rotating mating part is approximately an uneven structure. This uneven structure can effectively limit the rotation of the rotating unit; that is, the uneven structure plays a good limiting role along the circumference of the rotating unit, preventing the rotating unit from deviating significantly from the ideal initial state. This allows the key body and the rotating unit to accurately return to the tolerance range allowed by the ideal initial position, thus improving the reliability of the key structure's operation.

Detailed Implementation

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] See Figure 1 , Figure 2 , Figure 3 and Figure 4 One embodiment of this application provides a button structure 10 including a button body 100 and a keycap assembly 200. The button body 100 can be an encoder, etc. The keycap assembly 200 includes a rotating unit 210 and a rotating mating member 220. The rotating mating member 220 can slide relative to the button body 100 in the axial direction. The rotating unit 210 is disposed on one side of the rotating mating member 220 in the axial direction. The rotating unit 210 is fixedly connected to the button body 100. At least a portion of the rotating unit 210 near the rotating mating member 220 abuts against the rotating mating member 220. Along the axial direction of the rotating unit 210, two different areas on the periphery of the rotating unit 210 near the rotating mating member 220 are not equidistant from the button body 100. Figure 3 As shown, the distance from one area of ​​the periphery of the rotating unit 210 near the rotating mating member 220 to the button body 100 is H1, and the distance from another area of ​​the periphery of the rotating unit 210 near the rotating mating member 220 to the button body 100 is H2. Obviously, H2 is not equal to H1. In fact, H2 is greater than H1.

[0036] When the rotating unit 210 is rotated, it generates torque on the button body 100, causing the button body 100 to twist. Based on this twisting, the button body 100 can determine its angular displacement, thus enabling the button structure 10 to detect angular displacement. When the rotational force applied to the rotating unit 210 is removed, the torque on the button body 100 is released, allowing the button body 100 to return to its initial state under the action of elastic force. This also causes the button body 100 to drive the rotating unit 210 back to its initial position. It can be understood that the ideal initial state is when the rotating unit 210 accurately returns to its initial state. In actual use, a certain tolerance range will exist; that is, it is acceptable for the rotating unit 210 to return to a state that is a certain distance from the ideal initial state.

[0037] Since the distances between the two different areas of the periphery of the rotating unit 210 near the rotating mating part 220 and the button body 100 are not equal, the periphery of the rotating unit 210 near the rotating mating part 220 is roughly an uneven structure. Therefore, this uneven structure can effectively limit the rotation of the rotating unit 210. That is, the uneven structure plays a good limiting role for the rotating unit 210 along the circumference of the rotating unit 210, preventing the rotating unit 210 from deviating from the ideal initial state by a large distance. This allows the button body 100 and the rotating unit 210 to accurately return to the initial position, or in other words, the button body 100 and the rotating unit 210 to accurately return to the center position. This effectively prevents the button body 100 and the rotating unit 210 from swinging left and right near the center position, thus improving the reliability of the button structure 10.

[0038] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the button body 100 may be at least partially housed within the housing 400. The button body 100 includes a base 110 and a protrusion 120. The base 110 may be fixedly connected to the housing 400. The protrusion 120 protrudes from the base 110. The rotating unit 210 is fixedly connected to the protrusion 120. The rotating unit 210 drives the protrusion 120 to generate a torsion to achieve the detection of diagonal displacement. Two different areas on the periphery of the rotating unit 210 near the rotating mating member 220 are not equidistant from the base 110 of the button body 100.

[0039] See Figure 2 and Figure 4In some embodiments, the button structure 10 may further include an elastic element 300, which may be a spring or the like. The elastic element 300 is sleeved on the protrusion 120 of the button body 100 and abuts against the button body 100 and the rotating mating member 220. When the rotating mating member 220 slides close to the base 110 of the button body 100, the elastic element 300 is compressed and stores energy. When the elastic element 300 releases energy, it will push the rotating mating member 220 to move automatically away from the base 110. Therefore, the elastic element 300 can play the role of resetting the rotating mating member 220.

[0040] See Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the button structure 10 further includes a housing 400 and a fixing seat 500. The fixing seat 500 is disposed within the housing 400. The rotating fitting 220 is slidably connected to the fixing seat 500, and the rotating unit 210 is rotatably connected to the housing 400. The rotating fitting 220 includes a sliding sleeve 221 and a limiting protrusion 222. The sliding sleeve 221 abuts against the rotating unit 210, and the limiting protrusion 222 protrudes from the outer surface of the sliding sleeve 221. The fixing seat 500 has a sliding cavity 510, and a limiting groove 520 communicating with the sliding cavity 510 is recessed on the inner surface of the sliding cavity 510. The sliding sleeve 221 is slidably engaged with the sliding cavity 510, and the limiting protrusion 222 is slidably engaged with the limiting groove 520. Therefore, by the sliding engagement of the sliding sleeve 221 with the sliding cavity 510 and the sliding engagement of the limiting protrusion 222 with the limiting groove 520, the sliding accuracy of the sliding sleeve 221 in the axial direction can be improved. Furthermore, the circumferential limitation of the rotating mating part 220 can be achieved through the cooperation of the limiting protrusion 222 and the limiting groove 520. When the rotating unit 210 rotates, it prevents the rotating unit 210 from driving the rotating mating part 220 to rotate relative to the fixed seat 500, thereby ensuring that the rotating mating part 220 can only slide relative to the fixed seat 500. The elastic element 300 is at least partially housed within the sliding cavity 510, thus ensuring that the sliding cavity 510 effectively limits the elastic element 300 and that the direction of the elastic force generated by the elastic element 300 is always the extending direction of the sliding cavity 510, thereby ensuring the sliding accuracy of the rotating mating part 220.

[0041] See Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments, the rotating unit 210 has a plurality of first grooves 213 and a plurality of first protrusions 214 on the side near the rotating mating member 220. The plurality of first grooves 213 and the plurality of first protrusions 214 are arranged circumferentially along the rotating unit 210. The first protrusions 214 are disposed between two adjacent first grooves 213, such that a first protrusion 214 is formed between any two adjacent first grooves 213. The rotating mating member 220 has a plurality of second grooves 223 and a plurality of second protrusions 224 on the side near the rotating unit 210. The plurality of second grooves 223 and the plurality of second protrusions 224 are arranged circumferentially along the rotating mating member 220. The second protrusions 224 are disposed between two adjacent second grooves 223, such that a second protrusion 224 is formed between any two adjacent second grooves 223. The second grooves 223 and the second protrusions 224 are disposed on the sliding sleeve 221 of the rotating mating member 220. At the initial position of the rotating unit 210, the first protrusion 214 engages with the second groove 223, and the first groove 213 engages with the second protrusion 224. Therefore, when the torque of the rotating unit 210 on the protrusion 120 is removed, the protrusion 120 will drive the rotating unit 210 back to the initial position. The circumferential limiting effect generated by the interaction of the first protrusion 214 and the second groove 223, and the circumferential limiting effect generated by the interaction of the first groove 213 and the second protrusion 224, can effectively prevent the protrusion 120 and the rotating unit 210 from swinging and deviating within the tolerance range allowed by the ideal initial position. This ensures that the protrusion 120 and the rotating unit 210 accurately stay within the tolerance range of the ideal initial position, thereby improving the reliability of the button structure 10.

[0042] See Figure 1 For example, a first indicator strip 218 can be provided on the rotating unit 210, and a second indicator strip 410 can be provided on the housing 400. When the protrusion 120 and the rotating unit 210 return to their initial positions, the first indicator strip 218 and the second indicator strip 410 are aligned with each other in the circumferential direction without misalignment. In fact, if the protrusion 120 and the rotating unit 210 cannot accurately stop at the initial position, the first indicator strip 218 and the second indicator strip 410 will intermittently misalign and fail to align. Therefore, by the cooperation of the first protrusion 214 and the second groove 223, and the cooperation of the first groove 213 and the second protrusion 224, it can be ensured that the first indicator strip 218 and the second indicator strip 410 are always aligned in the circumferential direction, thus improving the reliability of the button structure 10.

[0043] See Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments, the rotating unit 210 includes two first inner wall surfaces 215 on the side near the rotating mating member 220. The two first inner wall surfaces 215 define a portion of the boundary of the first groove 213. This can also be understood as the first inner wall surface 215 being present between adjacent first grooves 213 and first protrusions 214. From one end of the first inner wall surface 215 near the bottom of the first groove 213 to one end near the top of the first protrusion 214, the rate of change of the distance between the first inner wall surface 215 and the base 110 gradually decreases. This can also be understood as the slope of the first inner wall surface 215 gradually decreasing, that is, the angle between the tangent of the first inner wall surface 215 and the axis of the protrusion 120 gradually increases, and the angle between the tangent of the first inner wall surface 215 and the base 110 gradually decreases. The rotating mating part 220 includes two second inner wall surfaces 225 on the side near the rotating unit 210. The two second inner wall surfaces 225 define a portion of the boundary of the second groove 223. This can also be understood as the second inner wall surface 225 being present between adjacent second grooves 223 and second protrusions 224. From the end of the second inner wall surface 225 near the bottom of the second groove 223 to the end near the top of the second protrusion 224, the rate of change of the distance between the second inner wall surface 225 and the base 110 gradually decreases. This can also be understood as the slope of the second inner wall surface 225 gradually decreasing, that is, the angle between the tangent of the second inner wall surface 225 and the axis of the protrusion 120 gradually increasing, and the angle between the tangent of the second inner wall surface 225 and the base 110 gradually decreasing.

[0044] In other embodiments, the rate of change of the distance between the first inner wall surface 215 and the base 110 from the end of the first inner wall surface 215 near the bottom of the first groove 213 to the end near the top of the first protrusion 214 can remain constant, or increase or decrease first. Similarly, the rate of change of the distance between the second inner wall surface 225 and the base 110 from the end of the second inner wall surface 225 near the bottom of the second groove 223 to the end near the top of the second protrusion 224 can remain constant, or increase or decrease first.

[0045] See Figure 3 , Figure 4 , Figure 5 and Figure 6 Therefore, the angle between the tangents of the first inner wall surface 215 and the second inner wall surface 225 and the base 110 can be denoted as α. During the process of the rotating unit 210 driving the protrusion 120 to twist, the rotating unit 210 will rotate relative to the rotating mating part 220. For example, when the rotating unit 210 and the protrusion 120 rotate relative to the rotating mating part 220 from their initial positions, i.e. Figure 3When the rotating unit 210 rotates counterclockwise, the first inner wall 215 gradually moves from the bottom end of the second inner wall 225 near the second groove 223 towards the top end of the second inner wall 225 near the second protrusion 224, and the rotating mating part 220 moves downward towards the base 110. The rotating unit 210 needs to overcome both the elastic torque f1 of the protrusion 120 and the contact force f2 of the second inner wall 225 on the first inner wall 215 and the entire rotating unit 210. This contact force generates a circumferential component force f2cosα, so f2cosα is the effective resistance that the rotating unit 210 actually needs to overcome. Therefore, the resistance F that the rotating unit 210 needs to overcome during rotation is F = f1 + f2cosα. As the rotation angle of the rotating unit 210 increases, f1 gradually increases while α gradually decreases, so f2cosα gradually decreases, thus making the value of the resistance F essentially constant. Therefore, as the rotation angle of the rotating unit 210 increases, the force driving the rotating unit 210 to rotate remains basically constant, avoiding the phenomenon that the force driving the rotating unit 210 to rotate increases with the increase of the rotation angle, thereby improving the convenience of operation of the entire button structure 10.

[0046] See Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments, the side of the rotating unit 210 near the rotating mating member 220 further includes a first bottom surface 216 and a first top surface 217. The first bottom surface 216 is connected between the ends of two first inner wall surfaces 215 that define the boundary of the same first groove 213 near the bottom of the first groove 213. The first top surface 217 is connected between the ends of two first inner wall surfaces 215 that define the boundary of two adjacent first grooves 213 near the top of the first protrusion 214. The rotating mating part 220 also includes a second bottom surface 226 and a second top surface 227 on the side near the rotating unit 210. The second bottom surface 226 is connected between the ends of the two second inner wall surfaces 225 that define the boundary of the same second groove 223 near the bottom of the second groove 223. The second top surface 227 is connected between the ends of the two second inner wall surfaces 225 that define the boundary of two adjacent second grooves 223 near the top of the second protrusion 224. The first bottom surface 216, the first top surface 217, the second bottom surface 226 and the second top surface 227 are all parallel to the surface of the base 110, that is, the distance from different positions of the first bottom surface 216 to the surface of the base 110 is equal, the distance from different positions of the first top surface 217 to the surface of the base 110 is equal, the distance from different positions of the second bottom surface 226 to the surface of the base 110 is equal, and the distance from different positions of the second top surface 227 to the surface of the base 110 is equal. This simplifies the manufacturing process of the rotating unit 210 and the rotating mating part 220 to some extent, thereby reducing the manufacturing cost of the button structure 10. On the other hand, during the rotation of the rotating unit 210 driving the protrusion 120 to rotate, when the first top surface 217 abuts against the second top surface 227, the value of f2cosα can be made close to zero, thus effectively ensuring that the value of the resistance F is basically constant.

[0047] See Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the rotating unit 210 includes a rotating member 211 and a pressing member 212. The pressing member 212 is fixedly connected to the button body 100 and is slidably connected to the rotating member 211 along the axial direction of the rotating unit 210. The rotating member 211 can drive the pressing member 212 to rotate. When a force is applied to the pressing member 212, the pressing member 212 will push the rotating mating part to overcome the elasticity of the elastic member 300 and move downward toward the base 110. This also causes the pressing member 212 to exert pressure on the protrusion 120, so the protrusion 120 will undergo compressive deformation. Of course, this compressive deformation is elastic deformation. When the pressure on the pressing member 212 is removed, the protrusion 120 will return to its original shape. Therefore, the sliding displacement of the pressing member 212 can be determined by the amount of compression deformation of the protrusion 120, thus realizing the detection of sliding displacement by the button structure 10.

[0048] See Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the rotating member 211 is slidably sleeved on the outside of the pressing member 212, and the pressing member 212 abuts against the rotating mating member 220. The first groove 213 and the first protrusion 214 are both disposed on the pressing member 212. The rotating member 211 includes a protruding strip 2111 protruding from the inner wall of the rotating member 211. A guide groove 2121 is recessed on the outer surface of the pressing member 212, and the guide groove 2121 slides with the protruding strip 2111. In the initial position of the rotating mechanism, the shape of the protruding strip 2111 matches the shape of the guide groove 2121. Through the sliding engagement of the guide groove 2121 and the protruding strip 2111, the rotating member 211 can be limited in the circumferential direction relative to the pressing member 212, i.e., preventing the rotating member 211 from rotating relative to the pressing member 212. Therefore, when a rotational force is applied to the rotating member 211, the rotating member 211 will drive the pressing member 212 to rotate synchronously. Furthermore, the pressing member 212 is fixedly connected to the protrusion 120. Therefore, the rotating member 211 drives the protrusion 120 to rotate through the pressing member 212. In this way, the rotational displacement of the rotating member 211 can be calculated by the rotational angle of the protrusion 120, and finally the button structure 10 can detect the rotational displacement.

[0049] Therefore, the rotation of the rotating component 211 enables the detection of rotational displacement of the button structure 10, while the sliding of the pressing component 212 enables the detection of sliding displacement. That is, rotational displacement is detected by the rotation of the rotating component 211, and sliding displacement is detected by the sliding of the pressing component 212. Thus, rotational and sliding movements are achieved through different independent parts, avoiding the use of the same parts, thereby ensuring smooth operation of both movements. This also reduces the allowable gap, making the button structure 10 more compact and enabling miniaturization. Furthermore, it simplifies the manufacturing process of the rotating unit 210, avoiding multiple processes such as multiple spraying or multi-color screen printing, thereby reducing the manufacturing cost of the button structure 10.

[0050] See Figure 4 , Figure 6 and Figure 7In some embodiments, the guide groove 2121 includes a first guide section 2121a, an intermediate guide section 2121c, and a second guide section 2121b. The second guide section 2121b is closer to the rotating mating member 220 than the first guide section 2121a. The intermediate guide section 2121c connects the first guide section 2121a and the second guide section 2121b. The width of the first guide section 2121a is greater than the width of the second guide section 2121b. The width of the intermediate guide section 2121c gradually decreases from the end of the intermediate guide section 2121c that is closer to the first guide section 2121a to the end that is farther away from the first guide section 2121a. During the sliding process of the pressing member 212 relative to the rotating member 211, the intermediate guide section 2121c can play a good guiding role for the sliding of the pressing member 212, avoid the pressing member 212 from getting stuck during the sliding process, improve the smoothness of the movement of the pressing member 212, thereby improving the reliability of the button structure 10 and ensuring that the button structure 10 accurately detects the sliding displacement.

[0051] See Figure 1 , Figure 2 , Figure 3 and Figure 8 In some embodiments, the outer casing 400 is provided with a rotating cavity 420. The outer casing 400 includes a plurality of protruding ribs 430 protruding from the inner side of the rotating cavity 420. The plurality of ribs 430 extend circumferentially along the rotating cavity 420 by a predetermined length and are spaced apart circumferentially along the rotating cavity 420, such that there is a gap between adjacent ribs 430. The outer side surface of the rotating component 211 of the rotating unit 210 is recessed with a plurality of arc-shaped grooves 2112. The plurality of arc-shaped grooves 2112 extend circumferentially along the rotating cavity 420 by a predetermined length and are spaced apart circumferentially along the rotating cavity 420. The ribs 430 engage with the arc-shaped grooves 2112. Therefore, during the assembly process of the rotating unit 210 and the outer casing 400, the arc-shaped grooves 2112 can be aligned with the gap between adjacent ribs 430, and then the rotating unit 210 can be rotated by a certain angle, thereby allowing the arc-shaped grooves 2112 to engage with the ribs 430. When it is necessary to disassemble the rotating unit 210 from the housing 400, the rotating unit 210 can be rotated so that the arc groove 2112 is aligned with the gap between two adjacent ribs 430. At this time, the interference of the ribs 430 can be eliminated, and the rotating unit 210 can be directly pulled out from the rotating cavity 420 to achieve unloading.

[0052] This application also provides a gaming device, which includes the aforementioned button structure 10. Therefore, by configuring the button structure 10, the reliability of the gaming device's operation can be improved.
