Description

Technical Field

[0002] Directional buttons are commonly found on modern game controllers and are mainly used to control the movement of game characters in the up, down, left, and right directions. Currently, the most common button shape used for directional input on game controllers is the D-pad.

[0003] The D-pad primarily works by pressing the keycaps, causing the conductors below the keys to move vertically downwards, thus connecting the circuit and controlling the movement of the game character. However, this triggering method, which relies on pressing the keycaps to move the conductors vertically downwards, makes the D-pad difficult to operate and provides a poor tactile feedback.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0044] Please refer to the reference. Figures 1 to 12 As shown, this utility model proposes a cross-shaped key module 100, which includes a keycap 1, a faceplate 12, a circuit board 4, and a rocker arm structure 2. The faceplate 12 has a through hole 121. The keycap 1 and the circuit board 4 are located on both sides of the faceplate 12, and the circuit board 4 has contacts. The rocker arm structure 2 is rotatably connected to the faceplate 12. The rocker arm structure 2 has a connecting rod 21 and a trigger part 22 connected to each other. One end of the connecting rod 21 passes through the through hole 121 and is connected to the keycap 1. The trigger part 22 is used to trigger the contacts. When the keycap 1 is pressed, the keycap 1 drives the trigger part 22 to rotate relative to the faceplate 12 through the connecting rod 21, and the trigger part 22 triggers the contacts.

[0045] Understandably, the D-pad module 100 is typically used in game controllers. The faceplate 12 serves as a support, providing mounting positions for the joystick structure 2 and keycaps 1. The keycaps 1 are located on the outside of the faceplate 12 for user operation. The circuit board 4 is located on the inside of the faceplate 12. The joystick structure 2 is situated between the faceplate 12 and the circuit board 4. The joystick structure 2 is connected to the keycaps 1 via a connecting rod 21 and triggers contacts on the circuit board 4 via a trigger part 22. During use, the circuit board 4 and the faceplate 12 are in a stationary relative position. The user presses the keycaps 1, causing the connecting rod 21 and the trigger part 22 to rotate relative to the faceplate 12, thereby triggering contacts on the circuit board 4. This causes the circuit board 4 to generate corresponding electrical signals, controlling the movement of the game character. In this application, the joystick structure 2 is rotatably connected to the faceplate 12, which enhances the flexibility of the D-pad module 100's triggering and effectively improves the user's feel.

[0046] In actual implementation, the side of the keycap 1 facing away from the faceplate 12 has four movement directions: up, down, left, and right. The circuit board 4 also has four contacts corresponding to these movement directions. The connecting rod 21 is connected to the center of the keycap 1 and also to the center of the trigger part 22. When the user does not press a movement direction, the keycap 1, connecting rod 21, and trigger part 22 are in the centered position, and the contacts on the circuit board 4 are not triggered. When the user presses a certain movement direction, the keycap 1 tilts in that direction, thereby causing the connecting rod 21 and trigger part 22 to rotate relative to the faceplate 12, thus triggering the contacts. The trigger part 22 also deflects in the direction of movement, and the trigger part 22 triggers the contact point on the circuit board 4 corresponding to the direction of movement, controlling the game character to move in the corresponding direction; when the user presses two adjacent directions of movement at the same time, such as up left, up right, down left, down right, the keycap 1 will deflect in the direction between the two adjacent directions of movement, thereby driving the connecting rod 21 and the trigger part 22 to rotate relative to the face shell 12, so that the trigger part 22 also deflects in the direction, realizing the simultaneous triggering of two adjacent contact points, controlling the game character to move in the direction of the 45° angle between the two adjacent directions of movement.

[0047] Optionally, the rocker structure 2 can be rotatably connected to the face shell 12 via the connecting rod 21, or via the trigger part 22, or via other components of the rocker structure 2, or via the cooperation of multiple components to achieve a rotatable connection with the face shell 12. The rocker structure 2 can achieve a rotatable connection with the face shell 12 via hinges, ball joints, or shaft hole cooperation, etc., without specific limitations.

[0048] Understandably, the game controller is enclosed by the front shell 12 and another shell to form a cavity. Typically, the front shell 12 is the upper shell, and the other shell is the lower shell. The relative connection between the upper and lower shells forms the cavity. The circuit board 4 is disposed within the cavity to isolate the circuit board 4 from the external environment and prevent the circuit board 4 from being interfered with or damaged.

[0049] In one embodiment of this utility model, such as Figures 1 to 7 As shown, the rocker structure 2 includes a rocker body and a rotating block 23. The rotating block 23 is rotatably connected to the face shell 12. The rocker body is provided with a connecting rod 21 and a trigger part 22. The connecting rod 21 is rotatably connected to the rotating block 23. The rotation axis of the rotating block 23 relative to the face shell 12 is arranged along a first direction, and the connecting rod 21 is arranged along a second direction relative to the rotation axis of the rotating block 23. The first direction and the second direction are perpendicular to each other.

[0050] In this embodiment, since the rotating block 23 has a degree of freedom to rotate relative to the faceplate 12 about a first direction, and the connecting rod 21 has a degree of freedom to rotate relative to the rotating block 23 about a second direction, that is, the connecting rod 21 has a degree of freedom to rotate about both the first and second directions, and the rotational degrees of freedom of the connecting rod 21 in the first and second directions can be superimposed. Thus, the connecting rod 21 and the trigger part 22 have a high degree of rotational flexibility, allowing the user to operate the buttons more conveniently.

[0051] Understandably, when keycap 1 is not pressed, keycap 1, joystick body and rotating block 23 are in the center position, and the extension direction of connecting rod 21 at this time is defined as the third direction, with the first direction, second direction and third direction being perpendicular to each other; when the moving direction on keycap 1 is pressed, since connecting rod 21 and trigger part 22 have the degree of freedom to rotate relative to faceplate 12 around the first direction and second direction, connecting rod 21 and trigger part 22 will tilt relative to the third direction towards the moving direction, thereby causing trigger part 22 to approach and trigger the contact point of circuit board 4 with the moving direction.

[0052] Taking the up, down, left, and right directions on keycap 1 as an example, the up and down direction can be set as the first direction, and the left and right direction can be set as the second direction. When keycap 1 is pressed in the up or down direction, the connecting rod 21 rotates relative to the rotating block 23 around the second direction, so that keycap 1 drives the connecting rod 21 and the trigger part 22 to deflect in the up or down direction, thereby causing the trigger part 22 to approach and trigger the corresponding contact point in the up or down direction; when keycap 1 is pressed in the left or right direction, the rotating block 23 rotates relative to the faceplate 12 around the first direction. This causes the keycap 1 to tilt the connecting rod 21 and the trigger part 22 to the left or right, thereby causing the trigger part 22 to approach and trigger the corresponding left or right tilt. When the keycap 1 is pressed in two adjacent directions, taking the up and right directions as examples, the rotating block 23 rotates relative to the face shell 12 around the first direction, while the connecting rod 21 rotates around the second direction, so that the keycap 1 causes the connecting rod 21 and the trigger part 22 to tilt in the direction between the up and right directions, thereby causing the trigger part 22 to approach and trigger the corresponding up and right contact points at the same time.

[0053] In actual implementation, the rotation axis of the rotating block 23 relative to the face shell 12 and the rotation axis of the connecting rod 21 relative to the rotating block 23 have an intersection point on the projection of the third direction. When the rocker structure 2 is in the centered position or tilted relative to the third direction, the extension line of the axis of the connecting rod 21 always passes through this intersection point. This can effectively improve the stability of the rocker structure 2 when it is in the centered position, and at the same time ensure the timeliness and accuracy of the keycap 1 driving the rocker structure 2 to trigger the circuit board 4 contacts, thereby improving the feel of the cross button module 100.

[0054] Optionally, the rotating block 23 and the faceplate 12 are rotatably connected via a shaft hole fit or a hinge, and the rotating block 23 and the connecting rod 21 are rotatably connected via a shaft hole fit or a hinge. The connecting rod 21 and the trigger part 22 can be integrally formed. The faceplate 12 and the rocker arm structure 2 can be made of plastic.

[0055] In one embodiment of this utility model, such as Figures 4 to 7 As shown, the faceplate 12 is provided with a mounting post 122, and a through hole 121 is provided through the mounting post 122. The mounting post 122 is also provided with a first shaft hole 1222 communicating with the through hole 121. The rotating block 23 is provided with a first rotating shaft 231, which extends along a first direction and is rotatably inserted through the first shaft hole 1222.

[0056] In this embodiment, a mounting post 122 is provided on the side of the faceplate 12 facing the circuit board 4. The connecting rod 21 passes through the through hole 121 of the mounting post 122 to connect with the keycap 1 on the other side of the faceplate 12. The rotating block 23 is rotatably connected to the shell through the shaft hole of the first rotating shaft 231 and the shaft hole of the first shaft hole 1222. The setting of the mounting post 122 increases the structural volume of the rotating block 23, and improves the strength and stability of the rotating connection between the faceplate 12 and the rotating block 23.

[0057] In actual implementation, the cross-sectional area of ​​the through hole 121 is larger than that of the connecting rod 21, so that the connecting rod 21 has sufficient space to deflect and move. Two first rotating shafts 231 can be provided, each located on one side of the rotating block 23. Correspondingly, two first shaft holes 1222 are also provided on the mounting post 122. The two first rotating shafts 231 can rotatably extend into the two first shaft holes 1222, ensuring the stability of the rotational fit between the rotating block 23 and the housing. Optionally, the mounting post 122 has a protrusion 1221 on its periphery facing the circuit board 4, and the first shaft hole 1222 is located on the protrusion 1221. This reduces the positioning difficulty during assembly of the first mounting shaft and the first shaft hole 1222, improving assembly efficiency. Simultaneously, the protruding design of the protrusion 1221 provides good elasticity, facilitating the insertion of the first rotating shaft 231 into the first shaft hole 1222.

[0058] Optionally, the first rotating shaft 231 can also be mounted on the mounting post 122, and the first shaft hole 1222 is mounted on the rotating block 23 corresponding to the first rotating shaft 231.

[0059] In one embodiment of this utility model, such as Figures 2 to 7 As shown, the rotating block 23 is also provided with a mounting cavity 232. The cavity wall of the mounting cavity 232 is provided with a second rotating shaft 233. The second rotating shaft 233 extends along a second direction. The connecting rod 21 is provided with a second shaft hole 211. The connecting rod 21 passes through the mounting cavity 232, and the second rotating shaft 233 is rotatably passed through the second shaft hole 211.

[0060] In this embodiment, the mounting cavity 232 is provided through the rotating block 23, the connecting rod 21 passes through the mounting cavity 232, and is rotatably connected to the rotating block 23 through the hole-shaft cooperation of the second shaft hole 211 and the second rotating shaft 233.

[0061] Understandably, the mounting cavity 232 allows the connecting rod 21 to be centered, and the extension line of the axis of the connecting rod 21 can pass through the intersection of the first rotating shaft 231 and the second rotating shaft 233 on the third-direction projection, which effectively improves the stability and reliability of the rocker structure 2 when it is centered and stationary and when it is rotating, and avoids the rocker structure 2 from accidentally touching the contacts on the circuit board 4.

[0062] In actual implementation, the cross-sectional area of ​​the mounting cavity 232 is larger than that of the connecting rod 21, so that the connecting rod 21, which passes through the mounting cavity 232, can rotate relative to the rotating block 23. Two second rotating shafts 233 are provided, respectively located on two opposite side walls of the mounting cavity 232. Correspondingly, two second shaft holes 211 are also provided on the connecting rod 21. The two second rotating shafts 233 rotatably extend into the two second shaft holes 211 to ensure the stability of the rotational engagement between the connecting rod 21 and the rotating block 23. Optionally, the second rotating shafts 233 can also be provided on the connecting rod 21, with the second shaft holes 211 corresponding to the second rotating shafts 233 located on the cavity wall of the mounting cavity 232.

[0063] In one embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the connecting rod 21 is also provided with a guide slope 212, which is used to guide the second rotating shaft 233 into the second shaft hole 211.

[0064] In this embodiment, when assembling the rotating block 23 and the rocker body, the rotating block 23 needs to be inserted from one end of the connecting rod 21, and then the rotating block 23 is moved along the connecting rod 21 until the second rotating shaft 233 is inserted into the second shaft hole 211.

[0065] In actual implementation, two second rotating shafts 233 and two shaft holes 211 are provided respectively. The connecting rod 21 includes a first section 213 and a second section 214 that are connected. When assembling the rotating block 23, the rotating block 23 is inserted from the end of the first section 213 that is away from the second section 214. The width of the first segment 213 in the second direction is less than or equal to the distance between the end faces of the two second rotating shafts 233, and the width of the second segment 214 in the second direction is greater than the distance between the end faces of the two second rotating shafts 233. The second shaft hole 211 is provided on the second segment 214. This reduces the difficulty of fitting the rotating block 23 into the first segment 213 and prevents the second segment 214 from coming out of the second shaft hole 211 after entering it. The guide slope 212 is provided at the connection between the first segment 213 and the second segment 214. When the rotating block 23 is moved from the first segment 213 to the second segment 214, the second rotating shaft 233 can move along the guide slope 212, reducing the difficulty of moving the rotating block 23 and improving the ease of assembly of the rotating block 23.

[0066] Optionally, the second shaft hole 211 is provided at one end of the connecting rod 21 near the trigger part 22, and the trigger part 22 is provided with a relief groove 221 corresponding to the rotating block 23, and the rotating block 23 is located in the relief groove 221.

[0067] In this embodiment, one end of the connecting rod 21 is connected to the keycap 1, and the other end of the connecting rod 21 is connected to the trigger part 22. The rotating block 23 is sleeved on the end of the connecting rod 21 near the trigger part 22 and is located in the clearance groove 221 provided in the rotating block 23, which makes the rocker structure 2 more compact and effectively saves assembly space.

[0068] In actual implementation, the first rotating shaft 231 of the rotating block 23 passes through the mounting hole 111 of the mounting post 122, and part of the mounting post 122 also extends into the mounting groove, thus further improving the compactness of the assembly of the rocker arm structure 2 and the face shell 12. When the first shaft hole 1222 is provided in the protrusion 1221 of the mounting post 122, the bottom of the mounting groove is also provided with a clearance hole 2221 for the protrusion 1221 to extend into.

[0069] In another embodiment of this utility model, such as Figures 8 to 12 As shown, a spherical protrusion 223 is formed on the side of the trigger part 22 away from the circuit board 4. The spherical protrusion 223 is connected to the connecting rod 21. The face shell 12 is provided with a spherical groove 123. The through hole 121 is provided through the bottom of the spherical groove 123. The spherical protrusion 223 is limited to the spherical groove 123.

[0070] In this embodiment, the rocker arm structure 2 is directly rotatably connected to the faceplate 12 via the trigger part 22. The trigger part 22 has a spherical protrusion 223, and the faceplate 12 has a spherical groove 123 corresponding to the spherical protrusion 223. The spherical protrusion 223 and the spherical groove 123 can be fitted together to form a structure similar to a ball joint. The spherical protrusion 223 can slide within the spherical groove 123, so that the trigger part 22 can rotate relative to the faceplate 12. The connecting rod 21 is connected to the center position of the spherical protrusion 223, and the through hole 121 is also provided through the center position of the spherical groove 123. When the spherical protrusion 223 and the spherical groove 123 are fitted together, the connecting rod 21 is also inserted into the through hole 121, and the end of the connecting rod 21 away from the spherical protrusion 223 is connected to the keycap 1.

[0071] Understandably, when the keycap 1 is not pressed, the keycap 1, connecting rod 21, and trigger part 22 are in the centered position, and the contacts on the circuit board 4 are not triggered. At this time, the extension direction of the connecting rod 21 is defined as the third direction. The spherical protrusion 223 and the spherical groove 123 can cooperate to allow the connecting rod 21 to deflect in any direction relative to the third direction. By pressing the keycap 1 in any direction of movement, the keycap 1 can drive the connecting rod 21 and the trigger part 22 to rotate relative to the faceplate 12, so that the connecting rod 21 and the trigger part 22 deflect in that direction, and the trigger part 22 triggers the contacts on the circuit board 4 corresponding to that direction.

[0072] In another embodiment of this utility model, such as Figures 9 to 11As shown, the faceplate 12 also includes limiting members 124 provided on both sides of the spherical groove 123. The limiting members 124 are provided with limiting grooves 1241, and the trigger part 22 is provided with limiting posts 224. The limiting posts 224 are movably limited in the limiting grooves 1241.

[0073] In this embodiment, to prevent the keycap 1 from causing the connecting rod 21 and the trigger part 22 to move around a third direction, the limiting member 124 and the trigger part 22 are limited by the limiting post 224 and the limiting groove 1241. When the spherical protrusion 223 is assembled into the spherical groove 123, the limiting post 224 extends into the limiting groove 1241 to prevent the keycap 1 from causing the rocker arm structure 2 to rotate around a third direction during use, which would prevent the trigger part 22 from triggering the contacts on the circuit board 4 in the preset direction.

[0074] Understandably, the extension direction of the limiting post 224 is set perpendicular to the third direction. The walls of the limiting post 224 and the limiting groove 1241 are not tightly attached to the limiting position to avoid affecting the rotation of the spherical protrusion 223 in the spherical groove 123.

[0075] In actual implementation, two sets of limiting members 124 and limiting posts 224 can be set accordingly. The two limiting members 124 are arranged opposite to each other on both sides of the spherical groove 123, and the two limiting posts 224 are respectively limited in the two limiting grooves 1241.

[0076] In embodiments of this utility model, such as Figure 7 and Figure 12 As shown, the keycap 1 is provided with a mounting rod 11, and the mounting rod 11 is provided with a mounting hole 111 that engages with the connecting rod 21, so that the keycap 1 and the rocker arm structure 2 can be detachably connected.

[0077] In this embodiment, the keycap 1 is detachably connected via the plug-in engagement of the connecting rod 21 and the mounting hole 111, allowing the keycap 1 to be removed from the joystick structure 2. This allows users to replace the keycap 1 according to their preference for feel, effectively improving the usability of the cross-shaped button module 100.

[0078] Understandably, the wall of the mounting hole 111 is matched with the circumferential surface of the connecting rod 21 that extends into the mounting hole 111, and the cross-sectional shape of the mounting hole 111 and the cross-sectional shape of the connecting rod 21 that extends into the mounting hole 111 are not circular, so as to avoid relative rotation between the keycap 1 and the connecting rod 21, which would cause the direction keys of the keycap 1 to not correspond to the contacts on the circuit board 4.

[0079] Optionally, the connecting rod 21 can be limited within the mounting hole 111 by a snap-fit ​​structure, which is not specifically limited here.

[0080] In embodiments of this utility model, such as Figure 1 , Figure 7 , Figure 8 and Figure 12 As shown, the circuit board 4 is provided with a plurality of tactile switches 41, each tactile switch 41 is configured as a contact, and the trigger part 22 is provided with a plurality of silicone parts 226, each silicone part 226 being configured in a one-to-one correspondence with a contact, and the silicone parts 226 being used to press and trigger the tactile switches 41.

[0081] In this embodiment, the tactile switch 41 serves as a contact point. When the tactile switch 41 is pressed, it is triggered. The triggering part 22 has a silicone element 226 corresponding to each tactile switch 41. When the keycap 1 and the rocker arm structure 2 are in the centered state without triggering the tactile switch 41, the silicone element 226 abuts against the corresponding tactile switch 41, but does not press to trigger it. When the keycap 1 drives the connecting rod 21 and the triggering part 22 to tilt towards a certain tactile switch 41, the triggering part 22 presses against the silicone element 226, causing the silicone element 226 to deform and press against the tactile switch 41, thus triggering it. When the user removes the external force on the keycap 1, the silicone element 226 rebounds, bringing the rocker arm structure 2 and the keycap 1 back to the centered state.

[0082] In actual implementation, taking the keycap 1 having four moving directions (up, down, left, and right) as an example, four tactile switches 41 are also provided on the circuit board 4, with each of the four tactile switches 41 corresponding to one of the four moving directions. The trigger part 22 is also provided with four silicone parts 226, with each of the four silicone parts 226 corresponding to one of the four tactile switches 41.

[0083] Understandably, the silicone part 226 provides some support for the joystick structure 2. When the keycap 1 and the joystick structure 2 are relatively small, the keycap 1 and the joystick structure 2 cannot rely on their own weight to drive the silicone part 226 to deform and trigger the tactile switch 41. However, through the support of the silicone part 226 for the joystick structure 2, the spherical protrusion 223 can be kept within the spherical groove 123.

[0084] Optionally, the trigger part 22 can be arranged in a disc shape or a cross shape, and no specific limitation is made here. The trigger part 22 is provided with a limiting hole 225 for each silicone part 226, and the silicone part 226 is limited in the limiting hole 225 by interference fit.

[0085] In an embodiment of this utility model, the circuit board 4 is provided with a plurality of conductive silicone buttons, each conductive silicone button being provided with a contact; optionally, the contact can also be other conductive rebound buttons, which are not specifically limited here.

[0086] In embodiments of this utility model, such as Figure 1 and Figure 7As shown, the cross button module 100 also includes a reset elastic element 3. One end of the reset elastic element 3 is connected to the trigger part 22, and the other end of the reset elastic element 3 is connected to the circuit board 4. The reset elastic element 3 is coaxially arranged with the connecting rod 21. The reset elastic element 3 is used to drive the rocker arm structure 2 to reset.

[0087] In this embodiment, a reset elastic element 3 is also provided between the trigger part 22 and the circuit board 4. When the user presses the keycap 1, causing the connecting rod 21 and the trigger part 22 to rotate relative to the faceplate 12, the reset elastic element 3 will deform. When the user stops pressing, the reset elastic element 3 will rebound and drive the rocker arm structure 2 to reset. The setting of the reset elastic element 3 can further ensure the stability of the reset function of the cross key module 100.

[0088] In actual implementation, the reset elastic element 3 can be a spring or a rubber pad, etc. The reset elastic element 3 is connected to the center position of the trigger part 22. When the rocker structure 2 is in the centered state, the reset elastic element 3 is coaxially arranged with the connecting rod 21. Thus, when the keycap 1 is subjected to force and causes the connecting rod 21 and the trigger part 22 to deviate relative to the face shell 12, the reset elastic element 3 also bends and deforms in the same direction. After the external force on the keycap 1 is removed, the reset elastic element 3 rebounds and drives the keycap 1 and the rocker structure 2 to reset.

[0089] Optionally, the reset elastic element 3 is a spring, and a positioning post 227 or a positioning groove can be provided on the side of the trigger part 22 facing the circuit board 4. The spring can be sleeved on the positioning post 227 or limited in the positioning groove to realize the connection with the trigger part 22.

Since this game controller adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0091] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
