Description

Technical Field

[0001] The present invention relates to the technical field of game controller buttons, and in particular to a segmented keycap for switching buttons and a button device using the same. Background Art

[0002] As the gaming industry continues to develop at a high speed, the game controller is a key input device for players to interact with games, and its functional diversity and convenience are crucial. As various types of games continue to innovate in gameplay and complexity, the demand for the number and functions of game controller buttons is also increasing. However, considering the aesthetics of the game controller and the operating habits of players, it is not appropriate to set too many keycaps on the surface space of the game controller. The current common practice is to add buttons to the PCB board of the game controller. For example, if two buttons share one keycap, this requires the two buttons to be rotated or translated to switch positions.

[0003] This solution has many disadvantages. On the one hand, it is necessary to add an independent button circuit board, which is then connected to the main control circuit board through a flexible circuit. It is also necessary to equip a turntable, a translation base, and a corresponding drive device (such as a motor, etc.) for driving the switching of the two buttons. This makes the internal structure of the handle complicated and the cost is greatly increased. On the other hand, due to the limited internal space of the handle, basically only two / groups of buttons can be set for switching, and it is difficult to achieve switching of three / groups or more. In addition, if the dual-button module is rotated or translated for a long time, the connection line is prone to problems such as poor contact, which seriously affects the reliability and service life of the handle.

[0004] In summary, the existing game controller button switching solutions cannot meet the growing number of buttons and functional requirements, and an innovative solution is urgently needed to break through these bottlenecks. Summary of the invention

[0005] The present invention is to solve the above-mentioned drawbacks and provides a segmented keycap for a switch key and a key device using the same.

[0006] The above-mentioned object of the present invention is achieved through the following technical solutions: a segmented keycap for switching keys, comprising a cap head and a cap body, the cap head and the cap body are rotatably connected, the cap head side wall is provided with a protrusion that cooperates with the game controller shell to limit the cap head, which is used to prevent the cap head from rotating with the cap body, and can prevent the direction of the key mark on the cap head from being changed, the cap body side wall is provided with a circle of gears, and the bottom of the cap body is provided with an anti-drop edge and a pressing end extending outward. The pressing end itself also has the function of preventing the key from detaching from the game controller shell, so the anti-drop edge can also be omitted.

[0007] The present invention also provides a key device using the above-mentioned segmented keycap, including the segmented keycap, a driving gear and a driving device, the driving device is connected to the driving gear, the driving gear is meshed with the gear teeth of the segmented keycap, at least two keys are provided on the lower side of the pressing end of the segmented keycap, and the pressing planes of all keys are flat.

[0008] Furthermore, in order to prevent the keycap from falling into the gap space between two adjacent keys during the switching process, the width of the pressing end of the segmented keycap is greater than the distance between the pressing ends of two adjacent keys, and the pressing planes of adjacent keys are level, so that the pressing end enters the pressing plane of the next key before completely leaving the pressing plane of the current key.

[0009] Furthermore, in order to prevent the keycap from falling into the gap between two adjacent keys during the switching process, a transition receiving member may be provided between the two adjacent keys, and the upper end surface of the transition receiving member is flush with the pressing plane of the key, so as to prevent the keycap from falling into the gap between the two adjacent keys during the switching process. Of course, an elastic body may be provided at the bottom of the cap body, and the elastic body may be a spring or a key silicone pad, so as to prevent the keycap from falling into the gap between two adjacent keys during the switching process, and at the same time, it can also provide assistance for resetting the key.

[0010] Furthermore, the driving device may be an electric driving device or a manual driving device.

[0011] Furthermore, the electric drive device may adopt a drive motor or a drive electric cylinder, etc.

[0012] Furthermore, the manual drive device may adopt a knob, a handwheel or a toggle switch, which is arranged on the surface of the game controller shell and can be operated by fingers, and drives the cap body of the segmented keycap to rotate through a mechanical transmission mechanism.

[0013] Furthermore, when the button devices on the game controller are arranged in groups of two or more, the button devices share a driving gear and a driving device, and the driving gear is engaged with the gear teeth of the keycap body in each group of button devices and rotates simultaneously.

[0014] Furthermore, the buttons include but are not limited to conductive glue buttons, touch buttons or micro switches.

[0015] The advantages of the present invention compared with the prior art are:

[0016] 1. Multi-button switching capability: Breaking through the limitations of existing technologies, it can easily switch between three or more buttons, greatly enriching the functions of the game controller and meeting the needs of players for complex game operations.

[0017] 2. Simple and stable structure: no complicated turntable, translation base and other structures are required, and there is no need to translate or rotate the internal electronic components, which reduces the connection lines and moving parts, reduces the probability of failure, and improves the stability and reliability of the handle.

[0018] 3. Anti-drop protection: Multiple anti-drop designs effectively prevent the keycaps from falling into the gap between keys during the switching process, ensuring the smoothness and accuracy of the player's operation and improving the gaming experience.

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0035] Example 1: Figure 1 As shown, a segmented keycap for switching keys includes a cap head 1 and a cap body 2, and the cap head 1 and the cap body 2 are rotatably connected, as shown in FIG. Figures 2 to 4 As shown, in this embodiment, the cap head 1 and the cap body 2 are connected by a bearing 11. Specifically, one of the cap head 1 and the cap body 2 is provided with a bearing groove 12, and the outer ring of the bearing is installed in the bearing groove 12 and connected with the bearing groove 12 by interference fit; the other is provided with a fixing rod 13, and the fixing rod 13 is connected with the inner ring of the bearing by interference fit. Figure 5 As shown, other methods may also be used, such as providing an axial hole 14 in one of the cap head 1 and the cap body 2, and providing a corresponding rotating shaft 15 in the other, and fixing magnets 16 that attract each other on the opposite surfaces of the two, so that the two are connected by magnetic force and can rotate coaxially under the limitation of the rotating shaft 15. Figure 1 As shown, the side wall of the cap head 1 is provided with a protrusion 3 that cooperates with the game controller housing to prevent the cap head 1 from rotating with the cap body 2, so that it can only be lifted and lowered longitudinally but cannot rotate circumferentially. The side wall of the cap body 2 is provided with a circle of gears 4, and the bottom of the cap body 2 is provided with an anti-dropping edge 17 and a pressing end 5 extending outward. The pressing end 5 itself also has the function of preventing the button from detaching from the game controller housing, so the anti-dropping edge 17 may not be provided.

[0036] Example 2: Figure 6 , Figure 7As shown, a key device includes a segmented keycap as described in Example 1, a driving gear 6 and a driving device 7, wherein the driving device 7 can be an electric driving device or a manual driving device, wherein the electric driving device can be a driving motor or a driving electric cylinder, etc., wherein the manual driving device can be a knob, a hand wheel or a toggle switch, wherein the knob, the hand wheel or the toggle switch is arranged on the surface of the game handle housing, and can be operated by a finger, and drives the cap body 2 of the segmented keycap to rotate through a mechanical transmission mechanism. The driving device 7 is connected to the driving gear 6, and the driving gear 6 is meshed with the gear 4 of the segmented keycap, and ensures that the driving gear 6 and the gear 4 are continuously meshed during the pressing action of the segmented keycap, and cannot be separated from each other, which not only plays a guiding role, but also prevents the gear from being misaligned. At least two buttons 8 are arranged on the lower side of the pressing end 5 of the segmented keycap, and the pressing planes of all the buttons 8 are flat. In this embodiment, two buttons 8 are arranged, and in other embodiments, three, four or any other buttons can also be arranged. The buttons 8 include but are not limited to conductive rubber buttons, touch buttons or micro switches. In order to prevent the keycap from falling into the gap space between two adjacent keys 8 during the switching process, the width of the pressing end 5 of the segmented keycap is set to be larger than the distance between the pressing ends 5 of two adjacent keys 8, and the pressing planes of adjacent keys 8 are level. It can be confirmed that the pressing end 5 has already rested on the pressing plane of the next key before completely leaving the pressing plane of the current key, thereby preventing the keycap from falling into the gap between two adjacent keys 8 during the switching process.

[0037] The working principle of the key device of this embodiment is as follows:

[0038] When the player needs to switch the button function, the operation method is different depending on the type of drive device 7 selected. If an electric drive device is used, for example, after the drive motor is started, the motor output shaft generates rotational power, which is transmitted to the drive gear 6 through the connection structure between the drive device 7 and the drive gear 6, and the drive gear 6 starts to rotate. Since the drive gear 6 is tightly meshed with the gear teeth 4 of the segmented keycap, according to the gear transmission principle, the rotation of the drive gear 6 drives the cap body 2 of the segmented keycap to rotate around the connection axis with the cap head 1. If a drive electric cylinder is used, the telescopic movement of the drive electric cylinder is converted into the rotation of the drive gear 6 through the corresponding mechanical conversion structure, thereby driving the cap body 2 to rotate.

[0039] If it is a manual drive device, when the player uses his fingers to operate the knob, hand wheel or toggle switch arranged on the surface of the game controller housing, the force generated by these manual operations is transmitted to the driving gear 6 through the mechanical transmission mechanism. The mechanical transmission mechanism can be a gear set, a connecting rod mechanism, etc., which converts the rotation or toggle action of the knob, hand wheel or toggle switch into the rotation of the driving gear 6, and also drives the cap body 2 to rotate.

[0040] During the rotation of the cap body 2, the pressing end 5 at the bottom thereof rotates accordingly. Since the width of the pressing end 5 is greater than the distance between the pressing ends of two adjacent keys 8, and the pressing planes of adjacent keys 8 are parallel, when the pressing end 5 rotates, before completely leaving the pressing plane of the current key, it has already rested on the pressing plane of the next key. In this way, the pressing end 5 sequentially contacts and presses at least two keys 8 below to achieve switching of different key functions. For example, when the pressing end 5 rotates from the first key to the second key, it has already begun to contact the second key in the process of leaving the first key, ensuring that the keycap will not fall into the gap space between the two adjacent keys 8 during the entire switching process, thereby ensuring the stability and reliability of key switching. Regardless of the driving mode, the key function switching can be achieved accurately and efficiently to meet the different operating requirements of players during the game.

[0041] Example 3: Figure 8 , Fig. 9 As shown, a key device includes a segmented keycap as described in Example 1, a driving gear 6 and a driving device 7, wherein the driving device 7 can be an electric driving device or a manual driving device, wherein the electric driving device can be a driving motor or a driving electric cylinder, etc., wherein the manual driving device can be a knob, a hand wheel or a toggle switch, wherein the knob, the hand wheel or the toggle switch is arranged on the surface of the game handle housing, and can be operated by a finger, and drives the cap body 2 of the segmented keycap to rotate through a mechanical transmission mechanism. The driving device 7 is connected to the driving gear 6, and the driving gear 6 is meshed with the gear 4 of the segmented keycap, and ensures that the driving gear 6 and the gear 4 are continuously meshed during the pressing action of the segmented keycap, and cannot be separated from each other, which not only plays a guiding role, but also prevents the gear from being misaligned. At least two buttons 8 are arranged on the lower side of the pressing end 5 of the segmented keycap, and the pressing planes of all the buttons 8 are flat. In this embodiment, four buttons 8 are arranged, and in other embodiments, two, three or any other buttons can also be arranged. The buttons 8 include but are not limited to conductive rubber buttons, touch buttons or micro switches. In order to prevent the keycap from falling into the gap between two adjacent keys 8 during the switching process, a transition receiving member 9 is provided between the two adjacent keys 8, the upper end surface of the transition receiving member 9 is flush with the pressing plane of the key 8, and the gap between the transition receiving member 9 and the keys on both sides is smaller than the width of the pressing end 5, so as to prevent the keycap from falling into the gap between two adjacent keys 8 during the switching process. In this way, the keycap is first placed on the transition receiving member 9 during the switching process, and then placed on the pressing plane of the next key by the transition receiving member 9.

[0042] The working principle of the key device of this embodiment is as follows:

[0043] When the player needs to switch the button function, the operation method is different depending on the type of drive device 7 selected. If an electric drive device is used, for example, after the drive motor is started, the motor output shaft generates rotational power, which is transmitted to the drive gear 6 through the connection structure between the drive device 7 and the drive gear 6, and the drive gear 6 starts to rotate. Since the drive gear 6 is tightly meshed with the gear teeth 4 of the segmented keycap, according to the gear transmission principle, the rotation of the drive gear 6 drives the cap body 2 of the segmented keycap to rotate around the connection axis with the cap head 1. If a drive electric cylinder is used, the telescopic movement of the drive electric cylinder is converted into the rotation of the drive gear 6 through the corresponding mechanical conversion structure, thereby driving the cap body 2 to rotate.

[0044] If a manual drive device is used, the player manipulates the knob, hand wheel or toggle switch on the surface of the game controller shell with his fingers, and the force generated by these manual operations is transmitted to the driving gear 6 via a mechanical transmission mechanism (such as a gear set, a connecting rod structure, etc.). The mechanical transmission mechanism efficiently converts the rotation of the knob, hand wheel or the toggle of the toggle switch into the rotation of the driving gear 6, thereby driving the cap body 2 to rotate.

[0045] During the rotation of the cap body 2, the pressing end 5 at the bottom thereof rotates synchronously. Since a transition receiving member 9 is provided between two adjacent buttons 8 in this embodiment, and the upper end surface of the transition receiving member 9 is in the same plane as the pressing plane of the button 8, the gap between the transition receiving member 9 and the buttons on both sides is smaller than the width of the pressing end 5. When the pressing end 5 rotates with the cap body 2, after leaving the pressing plane of the current button 8, it will first rest on the transition receiving member 9. Due to the supporting effect of the transition receiving member 9, the pressing end 5 will not fall into the gap between the buttons. Then, as the cap body 2 continues to rotate, the pressing end 5 rests on the pressing plane of the next button 8 from the transition receiving member 9. For example, when the pressing end 5 rotates from the first button to the second button, it will first contact and stabilize on the transition receiving member 9, and then smoothly transition to the pressing plane of the second button. In this way, the pressing end 5 contacts the pressing planes of the four buttons 8 below in turn, realizing smooth switching of different button functions. Whether it is electric drive or manual drive, it can stably and reliably achieve key function switching, fully meeting the players' operational needs in various game scenarios.

[0046] Example 4: Fig.10 , Fig.11As shown, a key device includes a segmented keycap as described in Example 1, a driving gear 6 and a driving device 7, wherein the driving device 7 can be an electric driving device or a manual driving device, wherein the electric driving device can be a driving motor or a driving electric cylinder, etc., wherein the manual driving device can be a knob, a hand wheel or a toggle switch, wherein the knob, the hand wheel or the toggle switch is arranged on the surface of the game handle housing, and can be operated by a finger, and drives the cap body 2 of the segmented keycap to rotate through a mechanical transmission mechanism. The driving device 7 is connected to the driving gear 6, and the driving gear 6 is meshed with the gear 4 of the segmented keycap, and ensures that the driving gear 6 and the gear 4 are continuously meshed during the pressing action of the segmented keycap, and cannot be separated from each other, which not only plays a guiding role, but also prevents the gear from being misaligned. At least two buttons 8 are arranged on the lower side of the pressing end 5 of the segmented keycap, and the pressing planes of all the buttons 8 are flat. In this embodiment, four buttons 8 are arranged, and in other embodiments, three, four or any other buttons can also be arranged. The buttons include but are not limited to conductive rubber buttons, touch buttons or micro switches. In order to prevent the keycap from falling into the gap between two adjacent keys 8 during the switching process, an elastomer is provided at the bottom of the cap body 2 so that the bottom surface of the pressing end 5 is flush with or slightly higher than the pressing plane of the key 8. The elastomer can be a spring or a key silicone pad 10. The key silicone pad 10 is used in this embodiment, which can not only prevent the keycap from falling into the gap between two adjacent keys 8 during the switching process, but also provide assistance for the key reset.

[0047] The working principle of the key device of this embodiment is as follows:

[0048] When the player needs to switch the button function, he or she first operates according to the type of drive device 7 selected. If an electric drive device is used, taking a drive motor as an example, after the motor is started, its output shaft generates rotational power. This power is accurately and efficiently transmitted to the drive gear 6 through the connection structure between the drive device 7 and the drive gear 6, and the drive gear 6 then starts to operate. Since the drive gear 6 is tightly engaged with the gear teeth 4 of the segmented keycap, according to the gear transmission principle, the rotation of the drive gear 6 drives the cap body 2 of the segmented keycap to rotate in a circle around the connection axis with the cap head 1. If a drive electric cylinder is used, the telescopic action of the electric cylinder is cleverly converted into the rotation of the drive gear 6 through a specific mechanical conversion structure, thereby driving the cap body 2 to rotate.

[0049] If a manual drive device is used, the player uses his fingers to operate the knob, hand wheel or toggle switch arranged on the surface of the game controller housing. The force generated by these manual operations is transmitted to the driving gear 6 through a mechanical transmission mechanism (such as a gear set, a connecting rod, etc.). The mechanical transmission mechanism converts the rotation of the knob, hand wheel or the toggle of the toggle switch into the rotation of the driving gear 6, thereby driving the cap body 2 to rotate.

[0050] During the rotation of the cap body 2, the pressing end 5 at the bottom thereof rotates synchronously. Since the elastic body, the key silicone pad 10, is provided at the bottom of the cap body 2, the bottom surface of the pressing end 5 is flush with or slightly higher than the pressing plane of the key 8. When the pressing end 5 rotates with the cap body 2, at the moment of leaving the pressing area of ​​the current key 8, the key silicone pad 10, with its elastic support, ensures that the pressing end 5 will not fall into the gap space between two adjacent keys 8. For example, when the pressing end 5 rotates from the first key to the second key, after leaving the pressing area of ​​the first key, the key silicone pad 10 will support the pressing end 5 to prevent it from falling. As the cap body 2 continues to rotate, the pressing end 5 gradually approaches the pressing area of ​​the second key until it contacts the second key and can be pressed. At the same time, when the player releases the key, the elasticity of the key silicone pad 10 can also provide assistance for the reset of the key, helping the key to quickly return to its initial state. In this way, the pressing end 5 contacts the four keys 8 below in turn, realizing smooth switching of different key functions. Whether it is electric drive or manual drive, it can stably and reliably switch the button functions, fully meeting the players' operational needs in various game scenarios.

[0051] Example 5: Fig.12 , Fig.13 and Fig.14 As shown, a key device includes the segmented keycap as described in Example 1, a driving gear 6 and a driving device 7, the driving device 7 is connected to the driving gear 6, the driving gear 6 is meshed with the gear teeth 4 of the segmented keycap, and it is ensured that during the pressing action of the segmented keycap, the driving gear 6 and the gear teeth 4 continue to maintain a meshing state and cannot be separated from each other, which not only plays a guiding role but also prevents the gear teeth from being misaligned. At least two buttons 8 are provided on the lower side of the pressing end 5 of the segmented keycap, and the pressing planes of all buttons 8 are flat. The accompanying drawings of this embodiment show three buttons. When two or more grouped key devices are provided on the game controller, the key devices share a driving gear 6 and a driving device 7, and the driving gear 6 is meshed with the keycap body gear teeth 4 in each group of key devices, and rotates and switches at the same time. This embodiment can be applied to the ABXY keys (grouped function keys) of the game controller. In order to prevent the keycap from falling into the gap between two adjacent keys 8 during the switching process, any of the methods used in Examples 2-4 can be used, that is, the width of the pressing end 5 of the segmented keycap is set to be greater than the distance between the pressing ends 5 of two adjacent keys 8 (refer to Figure 6 , Figure 7 ), or, a transition piece 9 is provided between two adjacent buttons 8, the gap between the transition piece 9 and the buttons on both sides is smaller than the width of the pressing end 5, or, an elastic body (such as a button silicone pad 10) is provided at the bottom of the cap body 2, so that the bottom surface of the pressing end 5 is flush with the pressing plane of the button 8 or slightly higher than the pressing plane of the button 8.

[0052] The working principle of the key device of this embodiment is as follows: when the player needs to switch the key function, the driving device 7 is operated. If an electric driving device is used, for example, the driving motor is started, and its output shaft outputs rotational power, and the power is transmitted to the driving gear 6 through the connection structure between the driving device 7 and the driving gear 6. Since the driving gear 6 is tightly meshed with the gear teeth 4 of the segmented keycaps in each group of key devices, according to the gear transmission principle, the rotation of the driving gear 6 synchronously drives the cap bodies 2 of all keycaps to rotate around the connecting axis with the cap head 1. If a driving electric cylinder is used, the telescopic action of the electric cylinder is converted into the rotation of the driving gear 6 through the mechanical conversion structure, and then all the cap bodies 2 are driven to rotate at the same time. If a manual driving device is used, the player's finger operates the knob, handwheel or toggle switch set on the surface of the game handle shell, and the generated force is transmitted to the driving gear 6 through the mechanical transmission mechanism (such as a gear set, a connecting rod mechanism, etc.). The mechanical transmission mechanism converts the rotation action of the knob, handwheel or toggle action of the toggle switch into the rotation of the driving gear 6, and then drives all the cap bodies 2 to rotate synchronously. During the rotation of the cap body 2, the pressing end 5 at the bottom thereof rotates synchronously. Since the anti-drop method in Examples 2-4 is adopted, the keycap can be effectively prevented from falling into the gap space between two adjacent keys 8 during the switching process. If the method of increasing the width of the pressing end 5 is adopted, when the pressing end 5 rotates to leave the pressing area of ​​the current key 8, because the width is greater than the distance between the pressing ends 5 of the adjacent keys 8, it can be ensured that the pressing area of ​​the next key is contacted before completely leaving the pressing area of ​​the current key. If a transition receiving member 9 is provided, after the pressing end 5 leaves the current key 8, it will first rest on the transition receiving member 9, and then reach the pressing area of ​​the next key 8 as the cap body 2 rotates. If an elastomeric keypad silicone pad 10 is provided at the bottom of the cap body 2, the bottom surface of the pressing end 5 is flush with or slightly higher than the pressing plane of the key 8. At the moment of leaving the current key 8, the elastic support of the key silicone pad 10 can prevent the pressing end 5 from falling. Taking the ABXY keys of the game controller as an example, through the drive of the driving device 7, the cap bodies 2 of all the keycaps rotate simultaneously, and the pressing ends 5 contact the three keys 8 below in sequence, so as to achieve simultaneous switching of the functions of different key groups. Whether it is electric drive or manual drive, the switching of the key functions of the group can be completed stably and reliably, meeting the complex operation requirements of players in the game.
