Description

Technical Field

[0001] Various embodiments relate to an input assembly for a controller. Specifically, various embodiments relate to an input assembly for a game controller (e.g., game controller buttons, joysticks, thumbsticks, etc.). Background Technology

[0002] In the gaming controller market, there is a growing demand for customizable and replaceable joystick caps. Currently, gaming controllers with interchangeable joystick caps typically utilize magnets to achieve this functionality, requiring the inclusion of ferromagnetic metal components within the cap. This metal integration not only adds a premium feel to the controller but also enhances the overall tactile experience.

[0003] However, the associated costs of incorporating metal into game controllers are relatively high. Furthermore, the use of magnetic components (such as magnets) may limit the types of sensors or switches suitable for game controllers. For example, magnets used for replaceable cap features may interfere with readings from Hall effect sensors within the controller.

[0004] Given the aforementioned limitations, an improved mechanism may be needed to provide a game controller with interchangeable cap functionality. Summary of the Invention

[0005] According to various embodiments, an input assembly for a controller can be provided. The input assembly may include a base and a cap. The base may include a cap receiving portion and a switch coupling portion. The switch coupling portion may be coupled to a switch module of the controller. The cap may include a connecting portion detachably connected to the cap receiving portion of the base along a connecting axis. The input assembly may further include a movable member disposed at the cap receiving portion of the base, the movable member being displaceable relative to the base between an extended position and a retracted position along a displacement axis not parallel to the connecting axis. In the extended position, the movable member may engage a engageable element of the cap to secure the cap to the base. In the retracted position, the movable member may disengage from the engageable element of the cap, allowing the cap to detach from the base. Attached Figure Description

Detailed Description

[0007] The embodiments described below in the context of the device are similarly effective for the corresponding methods, and vice versa. Furthermore, it should be understood that the embodiments described below can be combined; for example, a portion of one embodiment can be combined with a portion of another embodiment.

[0008] It should be understood that the terms “up,” “above,” “top,” “bottom,” “lower,” “side,” “back,” “left,” “right,” “front,” “side,” “upward,” etc., used in the following description are for convenience and to aid in understanding relative position or direction, and are not intended to limit the orientation of any device or structure, or any part of any device or structure. Furthermore, unless otherwise expressly indicated throughout the text, the singular terms “a” and “the” include the plural forms. Similarly, unless otherwise expressly indicated throughout the text, the word “or” is intended to include “and.”

[0009] Various embodiments generally relate to a transport assembly that provides interchangeable cap functionality for a game controller without requiring magnets and / or magnetic elements, such as metals.

[0010] The input assembly may include a base (e.g., a base assembly) that may be coupled to or secured to a switch of the controller. Additionally, the input assembly may include a cap (e.g., a cap assembly) that may serve as a cap or top portion of an input element (e.g., a button or joystick), which can be operated by a user to manipulate the controller.

[0011] According to various embodiments, the cap of the input assembly can be configured to be detachably connected to the base of the input assembly.

[0012] To secure the cap to the base, for example without requiring magnets and / or magnetic elements, the input assembly may include a movable member (e.g., another member different from the cap and base) that is movable between two positions relative to the base and cap when the base and cap are connected to each other. Specifically, in one position of the movable member (e.g., an extended position), for example, in a manner that allows the movable member to apply a force (e.g., a holding force) to the surface of the cap (e.g., a side surface) and / or in a manner that allows the movable member to lock onto the surface of the cap (e.g., a side surface), thereby preventing the cap from moving or separating from the base. In another position of the movable member (e.g., a retracted position), the movable member may shift away from the surface of the cap (e.g., a side surface) or may only slightly (e.g., lightly) contact the surface of the cap, thereby releasing the aforementioned holding force and / or unlocking from the surface of the cap. Thus, when the movable member is in this other (retracted) position, the cap can be easily removed or separated from the base.

[0013] Figure 1AThis is a schematic diagram depicting an input assembly 100 according to various embodiments, wherein the cap 120 of the input assembly 100 is separate from the base 110 of the input assembly 100.

[0014] Figure 1B It is a description of various embodiments. Figure 1A A schematic diagram of the input assembly 100, wherein the cap 120 is partially connected to the base 110.

[0015] Figure 1C It is a description of various embodiments. Figure 1A A schematic diagram of the input assembly 100, wherein the cap 120 is fully connected to the base 110.

[0016] According to various embodiments, an input assembly 100 may be provided. When fully assembled, the input assembly 100 can be used as a button, thumbstick, analog joystick, etc., of a controller (such as a game controller). The controller may be configured to control or provide input to electronic devices, such as game consoles or computers to which the controller may be paired or linked. Specifically, the input assembly 100 may be coupled or connected (e.g., detachably connected) to a switch module 102 of the controller (e.g., a switch, which may include a potentiometer, Hall effect sensor, optical sensor, etc.), and in this way, the input assembly 100 may be operable or movable (e.g., tilted or pressed inward) relative to the switch module 102 to control, operate, and / or actuate the switch module 102, thereby causing the controller to provide input or control signals to electronic devices (e.g., game consoles or computers).

[0017] According to various embodiments, the input assembly 100 may include several discrete or separate components (or may be formed from several discrete or separate components). Specifically, refer to Figure 1A The input assembly 100 may include (at least) a base 110 (e.g., a first component of the input assembly 100) and a cap 120 (e.g., a second component of the input assembly 100). As some examples, the cap 120 may be a cover or cap for a button on a controller, a joystick cover or cap, a thumb joystick cover or cap, etc. According to various embodiments, the base 110 and the cap 120 may be connectable to each other (e.g., detachably connected). Therefore, the input assembly 100 can replace a damaged cap 120 or interchange an existing cap 120 with another cap (e.g., of different length and / or different shape and / or size) according to user preference.

[0018] refer to Figure 1A According to various embodiments, the base 110 of the input assembly 100 may include a switch coupling portion 112. As an example, such as... Figure 1AAs shown, the switch coupling portion 112 may be located at the bottom or lower region of the base 110. Therefore, the switch coupling portion 112 of the base 110 may be coupled to or connected to the lower switch module 102 (e.g., a game controller, not shown). As some non-limiting examples, the switch coupling portion 112 and the switch module 102 may be coupled or connected to each other by snap-fit ​​connection, tight-fit connection, friction-fit connection, sliding connection, threaded engagement, by using adhesive, or by any other suitable connection method.

[0019] Additionally, according to various embodiments, the base 110 of the input assembly 100 may include a cap receiving portion 111. As an example, such as... Figure 1A As shown, the cap receiver 111 may be located opposite the switch coupling portion 112 of the base 110. Therefore, the cap receiver 111 may be located at the top or upper region of the base 110. According to various embodiments, the cap receiver 111 of the base 110 may be configured to be detachably connected to the connection portion 121 of the cap 120 of the input assembly 100 (described below).

[0020] According to various embodiments, the entire base 110 of the input assembly 100 may be a single piece and / or a monolithic structure or solid. That is, the entire base 110 assembly of the input assembly 100 may be a monolithic structure or may be formed integrally (e.g., without any different or separable parts or portions). Therefore, according to various embodiments, the switch coupling portion 112 and the cap receiving portion 111 may be integral parts of the base 110.

[0021] refer to Figure 1A According to various embodiments, the cap 120 of the input assembly 100 may include a connecting portion 121 configured to be detachably connected to a cap receiving portion 111 of the base 110. According to various embodiments, the connecting portion 121 of the cap 120 may be located in the bottom or lower region of the cap 120. Specifically, the cap 120 may include a head 123 (e.g., in the top or upper region of the cap 120, for direct engagement by a user's thumb or finger), and the connecting portion 121 of the cap 120 extends from the head 123 of the cap 120 (e.g., extending downwards). Figure 1A As shown, according to various embodiments, the connecting portion 121 of the cap 120 may be an elongated connecting portion 121 (e.g., similar to a shaft).

[0022] According to various embodiments, the entire cap 120 of the input assembly 100 may be a monolithic and / or integral structure or solid. That is, the entire cap 120 assembly of the input assembly 100 may be an integral structure or may be formed integrally (e.g., without any different or separable parts or portions). Thus, the head 123 and the connecting portion 121 may be integral parts of the cap 120. It is conceivable that, in other embodiments, the head 123 and the connecting portion 121 of the cap 120 may be discrete parts or components of the cap 120, which may be coupled in a manner that makes them immovable relative to each other (e.g., fastening, threaded engagement, etc.).

[0023] According to various embodiments, in order to detachably connect the cap 120 of the input assembly 100 to the base 110, the connecting portion 121 of the cap 120 can be aligned with the cap receiving portion 111 of the base 110 along a connecting axis 180 (e.g., a linear connecting axis 180), such as... Figure 1A As shown. According to various embodiments, the connecting shaft 180 may be, but is not limited to, a vertical (e.g., substantially vertical) reference shaft, along which the connecting portion 121 of the cap 120 and the cap receiving portion 111 of the base 110 can be moved toward each other to detachably connect the cap 120 to the base 110. Therefore, the connecting portion 121 of the cap 120 and the cap receiving portion 111 of the base 110 can be moved toward each other along the connecting shaft 180 until they are sufficiently (in other words, properly, completely, or fully) connected to each other, as... Figure 1C As shown. As some non-limiting examples, the connecting portion 121 of the cap 120 and the cap receiving portion 111 of the base 110 can be detachably connected to each other by sliding them relative to each other, by inserting one part into the other part, or by employing any other suitable detachable connection method.

[0024] According to various embodiments, the input assembly 100 may further include a movable member 130. According to various embodiments, the movable member 130 may be a third (or another) component of the input assembly 100, which is separate from or distinct from the cap 120 and base 110 of the input assembly 100. According to various embodiments, the movable member 130 may be disposed at the cap receiving portion 111 of the base 110 and may be linearly (e.g., substantially linearly) displaced or moved relative to the cap receiving portion 111 of the base 110 along a displacement axis 182. As an example, such as Figure 1A As shown, the cap receiving portion 111 of the base 110 may include a guide element 111b (e.g., a linear or substantially linear channel, passage, inlet / outlet, elongated hole, or track, etc.) (only when...) Figure 1AAs shown in the figure, the guide element 111b is configured to receive and / or guide the movable member 130 along the linear displacement axis 182. According to various embodiments, the displacement axis 182 may not be parallel to the connecting axis 180. Thus, as some examples, the displacement axis 182 may be at an acute or obtuse angle relative to the connecting axis 180 (e.g., the free end or tip of the movable member 130 faces diagonally downward or diagonally upward along the displacement axis 182), or the displacement axis 182 may be perpendicular to the connecting axis 180 (e.g., substantially perpendicular).

[0025] According to various embodiments, the movable member 130 is in an extended position along the displacement axis 182 (e.g., Figure 1A (as shown) and retraction position (as shown) Figure 1B The objects shown can be displaced or moved between the two sides.

[0026] Figure 1A The movable member 130 is in its extended position relative to the cap receiving portion 111 of the base 110, while the cap 120 is separated from the base 110. For example... Figure 1A As shown, when the movable member 130 is in the extended position, at least a portion (e.g., the free end) of the movable member 130 may be located at the connection 121 of the cap 120 when the cap 120 is away from the base 110. Specifically, as Figure 1A As shown, in the extended position of the movable member 130, at least a portion of the movable member 130 (e.g., the free end) can extend or protrude from the surface 111a (e.g., the wall surface) of the cap receiving portion 111 of the base 110. In other words, in the extended position of the movable member 130, the movable member 130 can partially protrude from the cap receiving portion 111 of the base 110. Therefore, when the cap receiving portion 111 of the base 110 is configured as a socket, as... Figure 1A As shown, in the extended position of the movable member 130, a portion of the movable member 130 (e.g., the free end) can extend into the socket space of the socket (i.e., the cap receiving portion 111) (e.g., inside).

[0027] Figure 1B The movable member 130 is shown in its retracted position relative to the cap receiving portion 111 of the base 110, while the cap 120 is partially connected to the base 110. According to various embodiments, by applying force to the movable member 130, the movable member 130 can move from its extended position (…). Figure 1A (As shown) shifted to the retracted position ( Figure 1B (as shown in the diagram). For example, movable member 130 may include surface segment 130a (see... Figure 1A(e.g., at its free end or upper corner), when the cap 120 is detachably connected to the base 110, the surface segment 130a engages the connection portion 121 of the cap 120. According to various embodiments, this surface segment 130a of the movable member 130 may be a flat or level surface segment 130a that is inclined (e.g., diagonally inclined) or inclined relative to the connecting shaft 180 (e.g., such that the surface segment 130a faces upward diagonally toward the connecting shaft 180), or the surface segment 130a may be a wavy surface or a curved surface. In this configuration of the movable member 130, (e.g., via the connection portion 121 of the cap 120 when the connection portion 121 of the cap 120 is connected to the cap receiving portion 111 of the base 110) applied to the surface segment 130a of the movable member 130 (e.g., in a downward direction along the connecting shaft 180) may cause the movable member 130 to move along the displacement axis 182 from an extended position (e.g., via the connection portion 121 of the cap 120). Figure 1A (As shown) Move or shift to the retracted position (e.g.) Figure 1B (As shown).

[0028] According to various embodiments, the connecting portion 121 of the cap 120 may similarly or identically include a corresponding surface segment (e.g., at its free end or corner) that engages with the aforementioned surface segment 130a of the movable member 130. The surface segment of the connecting portion 121 of the cap 120 may be configured similarly or identically to the aforementioned surface segment 130a of the movable member 130. This matching configuration between the movable member 130 and the cap 120 may facilitate sliding between the surface segment 130a of the movable member 130 and the corresponding surface segment of the connecting portion 121 of the cap 120, as they intersect (e.g., contact) and move relative to each other.

[0029] refer to Figure 1A and Figure 1B When the movable member 130 moves from the extended position ( Figure 1A (As shown) Move or shift to the retracted position ( Figure 1B When the cap 120 moves or is displaced (as shown in the diagram), it avoids the path of the connecting portion 121 of the cap 120. Specifically, according to various embodiments, as an example, the entire movable member 130 can retract into or be accommodated within the cap receiving portion 111 of the base 110 (e.g., in a channel or hole at the cap receiving portion 111 of the base 110). Afterward, the connecting portion 121 of the cap 120 can be further moved toward the cap receiving portion 111 of the base 110 until the connecting portion 121 of the cap 120 and the cap receiving portion 111 of the base 110 are fully connected to each other, as shown in the diagram. Figure 1C As shown.

[0030] refer to Figure 1CAccording to various embodiments, the connection portion 121 of the cap 120 may include a engageable element 122 that is aligned (e.g., horizontally or substantially horizontally aligned) with the movable member 130 (e.g., the free end of the movable member 130) when the connection portion 121 of the cap 120 is fully connected to the cap receiving portion 111 of the base 110.

[0031] As some non-limiting examples, the engageable element 122 may include or may be a horizontal or flush surface (or surface segment) of the connection portion 121 of the cap 120 (e.g., the movable member 130 may abut against and / or apply a holding force thereon), the outer surface (or surface segment) of the connection portion 121 of the cap 120 may be configured to have anti-slip properties (e.g., by means of texture and / or composed of a material with anti-slip properties), or may be a notch, groove, socket, recess, etc. on the surface (e.g., side surface) of the connection portion 121 of the cap 120 (e.g., the movable member 130 may snap onto it).

[0032] Therefore, when the connecting portion 121 of the cap 120 is fully connected to the cap receiving portion 111 of the base 110, as Figure 1C As shown, the movable member 130 can be moved or displaced to an extended position (e.g., from a retracted position) to engage (e.g., abut, contact, interface, snap, etc.) the engageable element 122, thereby securing the cap 120 to the base 110.

[0033] According to various embodiments, the input assembly 100 may include (e.g., as needed or further include) a biasing element 140 configured to push the movable member 130 to an extended position. Thus, the movable member 130 can be biased by the biasing element 140 to remain in the extended position without any external force acting on it. As some non-limiting examples, the biasing element 140 may include or be a spring (e.g., a coil spring, a torsion spring, etc.), an elastic band (e.g., a rubber band), memory foam, etc. For illustration, one end or portion of the biasing element 140 may be coupled to the base 110 (e.g., coupled to the cap receiver 111 of the base 110), while the other end or portion of the biasing element 140 may be coupled to the movable member 130, thereby biasing the movable member 130 relative to the base 110. Therefore, according to various embodiments, when the biasing element 140 is incorporated into the input assembly 100, the movable member 130 may be biased toward the engageable element 122 of the cap 120, or may be pushed against the engageable element 122 of the cap 120 to secure the cap 120 to the base 110.

[0034] Conversely, in order to detach or remove the cap 120 from the base 110, the movable member 130 can be moved or displaced to a retracted position, such that the movable member 130 disengages (e.g., separates or moves away from) the engageable element 122 at the connection 121 of the cap 120. Afterward, the cap 120 of the input assembly 100 can be easily detached from and removed from the base 110 of the input assembly 100.

[0035] Although Figure 1C A single movable member 130 is shown for securing the cap 120 to the base 110, but it is conceivable that in other embodiments, the input assembly 100 may include multiple (e.g., two or more) movable members 130 that are similarly or identically configured to secure the cap 120 to the base 110.

[0036] According to various embodiments, since the movable member 130 is configured as a mechanism for fastening the cap 120 to the base 110 (as described above), the cap 120 and / or the base 110, or the entire input assembly 100 itself, may not require or need to employ, utilize, or incorporate any magnetic elements (e.g., magnetic materials and / or ferromagnetic materials and / or magnets, etc.). For example, the cap 120 may include or be composed of non-ferromagnetic and / or non-magnetic materials (or material composites) (e.g., polymers or plastics and / or rubber, any non-metallic or non-metallic materials, etc.). Specifically, the entire cap 120 may be constructed of non-ferromagnetic and / or non-magnetic materials (or material composites). Similarly, the base 110 may include or be composed of non-ferromagnetic and / or non-magnetic materials (or material composites) (e.g., polymers or plastics, any non-metallic or non-metallic materials, etc.). Specifically, the entire base 110 may be constructed of non-ferromagnetic and / or non-magnetic materials (or material composites). Additionally, according to various embodiments, the movable member 130 of the input assembly 100 may include or may (e.g., optionally) be made of a non-ferromagnetic and / or non-magnetic material (or material composite). Therefore, the input assembly 100 can provide a controller with the ability to replace or interchange the cap 120 without or using any magnetic elements to secure the cap 120 to the base 110.

[0037] Figure 1D It is a description of various embodiments. Figure 1A A schematic diagram of the input assembly 100 being manipulated relative to the switch module 102.

[0038] like Figure 1DAs shown, when the cap 120 is fastened to the base 110, the cap 120 is operable (e.g., in any direction) relative to the switch module 102 (i.e., coupled to the base 110) to operate (e.g., a game controller) the switch module 102 by means of the engagement of the movable member 130 at the base 110 and the engageable element 122 at the cap 120.

[0039] refer to Figures 1A to 1D According to various embodiments, the input assembly 100 may include (e.g., optionally or further include) an anti-rotation configuration 150 configured to prevent the cap 120 from rotating relative to the base 110 (e.g., about the connecting shaft 180) (i.e., when the connecting portion 121 of the cap 120 is fully connected to the cap receiving portion 111 of the base 110, such as...). Figure 1C As shown). To illustrate, as Figure 1A and Figure 1B As shown, the cap receiving portion 111 of the base 110 may include an anti-rotation fitting element 151, and the connecting portion 121 of the cap 120 may include a complementary anti-rotation fitting element 152. According to various embodiments, the anti-rotation fitting element 151 and the complementary anti-rotation fitting element 152 can cooperate with each other, such as... Figure 1C and Figure 1D As shown, in this manner, when the cap 120 is fully engaged, any rotational or rotational movement of the cap 120 relative to the base 110 (e.g., about the connecting shaft 180) can be prevented or suppressed. As a non-limiting example, the anti-rotational mating element 151 and the complementary anti-rotational mating element 152 can be configured to engage or mate in a sliding engagement manner using a tongue (e.g., a protrusion, tab, etc.) and a slot. For example, the aforementioned tongue can be located at the cap receiving portion 111 of the base 110, while the aforementioned slot can be located at the connecting portion 121 of the cap 120, or vice versa. As another non-limiting example, the anti-rotational mating element 151 and the complementary anti-rotational mating element 152 can be anti-slip elements, such as textured surfaces or anti-slip materials.

[0041] Figure 2B It is coupled to various embodiments Figure 2A A close-up side view of the input assembly 200 of the switch module 202 of the controller 2000.

[0042] like Figure 2AAs shown, a controller 2000 may be provided, such as a game controller for a game console. The controller 2000 may include a plurality of input components 2001 (e.g., buttons, joysticks, thumb joysticks, etc.) that can be manipulated by a user (e.g., pressed, moved, etc.) to control a game console (not shown) that can be paired with the controller 2000.

[0043] According to various embodiments, at least one of the aforementioned input components 2001 of the controller 2000 may be provided in the form of an input assembly 200, as described herein.

[0044] According to various embodiments, the input assembly 200 may include... Figures 1A to 1D The input assembly 200 includes any one or more features and / or limitations. In the following, input assembly 200 is generally referred to as... Figures 1A to 1D The input assembly 100 is described using the same component symbols for the same or corresponding parts / features. Descriptions of the parts / features of the input assembly 200 can also be applied to the input assembly 100, and vice versa.

[0045] refer to Figure 2A As an illustration, the input assembly 200 can be configured or used as a thumb joystick for the controller 2000 (e.g., having a removable or interchangeable thumb joystick cover or cap 220).

[0046] Specifically, the input assembly 200 can be coupled to a switch module 202 of the controller 2000 (e.g., a thumb joystick switch module 202 or a thumb joystick switch) located within the housing of the controller 2000. (See reference) Figure 2B As an example, the switching module 202 of the controller 2000 may include a post 202a (e.g., an elongated and / or cylindrical post) that can be coupled to the switching coupling portion 212 of the base 210 of the input assembly 200. As an example, such as Figure 2BAs shown, the switch coupling portion 212 of the base 210 of the input assembly 200 may include or may be in the form of a socket (e.g., a blind hole), which is configured (e.g., shaped and / or sizing) to accommodate (e.g., receive or mount thereon) the post 202a of the switch module 202. Thus, the post 202a of the switch module 202 can be inserted into the socket of the base 210 of the input assembly 200, thereby coupling the base 210 of the input assembly 200 to the switch module 202 of the controller 2000. Furthermore, according to various embodiments, the socket of the base 210 and the post 202a of the switch module 202 can be configured for a tight fit or a friction fit engagement. Therefore, the post 202a of the switch module 202 can be operated or actuated by moving (or manipulating) the cap 220 of the input assembly 200 (i.e., which is detachably connected to the base 210 of the input assembly 200). According to various embodiments, movement (e.g., in any direction) of the post 202a of the switch module 202 can be sensed by one or more sensors (e.g., potentiometers or Hall effect sensors) incorporated in the switch module 202 of the controller 2000. Therefore, the controller 2000 can output a control signal corresponding to the sensed or detected movement of the post 202a for controlling a game console (not shown) that can be paired with the controller 2000.

[0047] According to various embodiments, such as Figure 2B As shown, the base 210 of the input assembly 200 may further include a cap receiving portion 211 (e.g., opposite to the switch coupling portion 212). As an example, such as Figure 2B As shown, the cap receiving portion 211 of the base 210 may include or may be in the form of a shaft (e.g., an elongated and / or cylindrical shaft) or a handle, which can be detachably connected to the connecting portion 221 of the cap 220 of the input assembly 200. As shown, the shaft may extend along the connecting shaft 280 or in a direction parallel to the connecting shaft 280.

[0048] According to various embodiments, such as Figure 2BAs shown, the input assembly 200 may further include a cap 220, which may include a connecting portion 221 configured to be detachably connected to a cap receiving portion 211 (e.g., a shaft) of the base 210. As shown, the connecting portion 221 of the cap 220 may include or may be in the form of a sleeve (e.g., a sleeve with a hollow or vacant structure), which may be fitted or sleeved (e.g., detachably sleeved) over the shaft (i.e., the cap receiving portion 211) along the connecting shaft 280, thereby detachably connecting the sleeve (i.e., the connecting portion 221) to the shaft (i.e., the cap receiving portion 211). According to various embodiments, the sleeve may include continuous sidewalls, which may be free of any discontinuities, breaks, gaps (e.g., slits), etc. Therefore, when the sleeve (i.e., the connecting portion 221) and the shaft (i.e., the cap receiving portion 211) are detachably connected, the sleeve, specifically, its sidewalls, may surround (e.g., completely surround) the shaft.

[0049] According to various embodiments, such as Figure 2B As shown, the cap 220 of the input assembly 200 may further include a head 223 abutting the sleeve (i.e., the connection 221) at one end of the sleeve. Furthermore, as shown, the head 223 may include (e.g., as needed or further included) an anti-slip layer 224 (e.g., made of an anti-slip material such as rubber) to enhance grip and prevent slippage between the user's fingers and the head 223 of the cap 220.

[0050] like Figure 2B As shown, according to various embodiments, when the shaft (i.e., the cap receiving portion 211) is fully connected (e.g., fully inserted) to the sleeve (i.e., the connecting portion 221), the head 223 of the cap 220 can engage one end of the shaft to prevent the shaft from extending further into the cap 220. Therefore, according to various embodiments, the head 223 of the cap 220 can be used as a brake to limit how far the shaft of the base 210 can extend into the cap 220.

[0051] Alternatively or alternatively, according to various embodiments, such as Figure 2B as well as Figure 2F and Figure 2G As shown, the base 210 of the input assembly 200 may include a flange (e.g., a conical flange) 216 located at one end (e.g., the bottom end) of the shaft (i.e., the cap receiving portion 211) of the base 210. According to various embodiments, see reference... Figure 2B When the shaft is fully connected (e.g., fully inserted) to the sleeve (i.e., the connecting portion 221), the free end of the sleeve can engage the flange portion 216 of the base 210. Therefore, according to various embodiments, the flange portion 216 of the base 210 can also be configured to function as a brake to limit how far the shaft of the base 210 can be inserted into the cap 220.

[0052] Additionally, refer to Figure 2B as well as Figure 2F and Figure 2G According to various embodiments, the upper surface of the flange 216 of the base 210 (e.g., opposite to the switch coupling portion 212) may include or define a groove 215 (e.g., a circular or annular groove) configured to receive the free end of the sleeve (e.g., which may be the circular or annular end of the sleeve, i.e., the connection portion 221). Furthermore, as... Figure 2B As shown, the free ends of the slot 215 and the sleeve may have matching shapes (e.g., matching "stepped" shapes) and dimensions, which may facilitate the positioning and alignment of the cap 220 relative to the base 210.

[0053] According to various embodiments, such as Figure 2B As shown, the input assembly 200 may further include a movable member 230. The movable member 230 may be a component separate from both the base 210 and the cap 220.

[0054] refer to Figure 2B According to various embodiments, the cap receiving portion 211 may include a channel (e.g., a linear, elongated, and / or cylindrical channel, such as a hollow channel) in which or along the channel is the movable member 230 disposed or accommodated. Thus, the channel may resemble (or be analogous to) a hole or a hollow channel. Figure 2B As shown, the channel may be located at the cap receiving portion 211 (e.g., shaft) of the base 210. Specifically, the channel may extend from one side (e.g., side surface) of the cap receiving portion 211 to the cap receiving portion 211. The channel may also be oriented along a linear axis (i.e., displacement axis 282 of the movable member 230) that is not parallel to (e.g., perpendicular or substantially perpendicular to) the connecting shaft 280. Therefore, the movable member 230 may be disposed or placed within the channel and may freely linearly displace within the channel along the displacement axis 282 that is not parallel to the connecting shaft 280.

[0055] Specifically, according to various embodiments, the movable member 230 can be displaced along the main portion (e.g., an elongated portion) of the channel while being prevented from moving out of or sliding out of the main portion of the channel. For example, the main portion of the channel may have a width (e.g., uniform or substantially uniform) that is substantially equal to or greater than the width (e.g., maximum width) of the movable member 230. The channel may further include a channel opening at an end of the main portion of the channel. The channel opening may be located on one side (e.g., a side surface) of the cap receiving portion 211 of the base 210. The channel opening may have a width smaller than the width of the movable member 230. In other words, the width of the channel opening may be smaller than the width of the main portion of the channel. In this way, the movable member 230 within the channel can be displaced along the entire main portion of the channel, but is prevented from sliding out of the channel through the channel opening.

[0056] Figure 2C This is a perspective view of the movable component fixing seat 260 of the input assembly 200 according to various embodiments.

[0057] refer to Figure 2C According to various embodiments, the input assembly 200 may include (for example, as needed or further include) a movable member mounting base 260, which may define the aforementioned channel for placing or accommodating the movable member 230.

[0058] Therefore, the movable component mounting base 260 can be a modular or detachable component of the input assembly 200. For illustration, refer back to the reference. Figure 2B The cap receiving portion 211 of the base 210 may include or define a socket 217 extending inwardly from one side (e.g., a side surface) of the cap receiving portion 211 of the base 210. The socket 217 may be sized to receive a movable member holder 260 (e.g., at least a hollow cylindrical portion 261 of the movable member holder 260). Thus, the movable member holder 260 can be inserted (e.g., detachably inserted) into the socket 217 at the cap receiving portion 211 of the base 210, allowing the movable member 230 to be displaced along a displacement axis 282 along a channel defined by the movable member holder 260. According to various embodiments, the movable member holder 260 can be inserted into the socket 217 at the cap receiving portion 211 of the base 210 using a tight fit, press fit, or friction fit engagement. Additionally, an adhesive may be applied (e.g., as needed or further) to secure the movable member holder 260 to the cap receiving portion 211 of the base 210.

[0059] refer to Figure 2B and Figure 2C According to various embodiments, the movable component fixing seat 260 may include a hollow cylindrical portion 261, which may correspond to or define the main portion of the channel.

[0060] Furthermore, the movable member fixing seat 260 may include an opening at its front end. This opening of the movable member fixing seat 260 may correspond to or define a channel opening.

[0061] like Figure 2B As shown, when the movable member holder 260 is inserted into the socket 217 of the cap receiving portion 211 of the base 210, the rear end of the movable member holder 260 can be covered or sealed (e.g., by means of the cap receiving portion 211 of the base 210). Therefore, within the input assembly 200, the channel for the movable member 230 can be a blind channel (e.g., similar to a blind hole).

[0062] Additionally, refer to Figure 2C According to various embodiments, the movable member holder 260 may include a lip 262 (e.g., a flange) extending laterally from the front end of the hollow cylindrical portion 261 of the movable member holder 260. According to various embodiments, the lip 262 may function as a brake to limit how far the hollow cylindrical portion 261 of the movable member holder 260 can be inserted into the socket 217 of the cap receiver 211 of the base 210 by engaging with its side surface (e.g., adjacent to and / or surrounding the socket opening 217a). Figure 2B As shown.

[0063] refer to Figure 2B According to various embodiments, the input assembly 200 may include (for example, further include) a bias element 240. Specifically, as an example, such as Figure 2B As shown, the biasing element 240 can be a spring disposed within the movable member holder 260. A first end of the biasing element 240 can be coupled to the movable member 230, while the opposite second end of the biasing element 240 can be coupled (e.g., directly or indirectly via the movable member holder 260) to the cap receiving portion 211 of the base 210. Therefore, within the input assembly 200, the biasing element 240 (e.g., a spring) can be sandwiched between the movable member 230 and the cap receiving portion 211 of the base 210. In this way, when no other external force is applied to or resisted by the movable member 230 (e.g., against the biasing of the biasing element 240), the biasing element 240 can bias or push the movable member 230. Figure 2B The extended position shown.

[0064] According to various embodiments, the movable member retainer 260, together with the movable member 230 and the biasing element 240 (e.g., disposed within the movable member retainer 260), may be referred to as a "spherical plunger configuration." The spherical plunger configuration may resemble a spring-loaded spherical pawl or a spring-loaded spherical plunger. Therefore, according to various embodiments, the movable member 230 may be a spherical movable member 230 (in other words, it may have a spherical shape) and may be made of a hard and / or rigid material (e.g., a hard and rigid polymer, or a non-magnetic metal, such as aluminum, copper, steel / non-magnetic steel, etc.) to serve as a pawl ball. It is conceivable that, according to various embodiments, the spherical movable member 230 may be freely spin or rotate (e.g., about its center) while also being freely translated (e.g., linearly) along a linear displacement axis 282.

[0065] According to various embodiments, such as Figure 2B and Figure 2CAs shown, when the movable member 230 is in the extended position, a portion of the movable member 230 can protrude outward from the channel opening (i.e., have a width or diameter smaller than the movable member 230 itself), and thus the side away from the cap receiving portion 211 of the base 210 faces the connecting portion 221 of the cap 220 (i.e., detachably connected to the cap receiving portion 211 of the base 210). In this way, as Figure 2B As shown, the movable member 230 (e.g., its protruding portion) can engage the engageable element 222 at the connection portion 221 of the cap 220 to secure the cap 220 to the base 210.

[0066] Figure 2D This is a bottom perspective view of the cap 220 of the input assembly 200 according to various embodiments.

[0067] Figure 2E According to various embodiments Figure 2D A cross-sectional view taken along line AA of the cap 220.

[0068] refer to Figure 2D and Figure 2E According to various embodiments, the engageable element 222 of the cap 220 may include or may be a recessed portion or notch serving as a movable member 230 (e.g., at least a protruding portion of the movable member). This engageable element 222 may be located at the connection portion 221 (e.g., the sleeve) of the cap 220. Specifically, the engageable element 222 may be a recessed region or inward recess along the inner wall surface of the sleeve (i.e., the connection portion 221) of the cap 220. As an example, such as Figure 2B As shown, the shape and / or size of the engageable element 222 may correspond to (e.g., match) the shape and / or size of the protrusion of the movable member 230 (i.e., at the extended position of the movable member 230). For example, the movable member 230 may be a spherical movable member 230 (e.g., a ratchet ball), and the engageable element 222 may be a recessed area on the inner wall surface of a sleeve (i.e., a connection 221) whose shape and / or size is similar to or the same as the protrusion of the spherical movable member 230. It is conceivable that in other embodiments, the shape and / or size of the engageable element 222 may differ from the shape and / or size of the protrusion of the movable member 230 (i.e., at the extended position of the movable member 230).

[0069] According to various embodiments, when the movable member 230 (e.g., at least its protruding portion) engages (e.g., is accommodated therein, interfaces with, or fits) with the engageable element 222 of the cap 220, the cap 220 may not be able to move freely (e.g., slide or drift) away from the base 210 unless the user moves (e.g., pulls) the cap 220 away from the base 210 with a force (e.g., on the order of magnitude of the biasing force overcoming the biasing element 240) that moves or displaces the movable member 230 away from the extended position (e.g., away from the connection 221 of the cap 220, and more specifically, away from the engageable element 222 at the connection 221 of the cap 220) to the retracted position. According to various embodiments, when the movable member 230 moves or displaces to the retracted position, the movable member 230 disengages from the engageable element 222, thereby allowing the cap 220 to be easily separated from or removed (e.g., disconnected) from the base 210.

[0070] Figure 2F This is a perspective view of the base 210 of the input assembly 200 according to various embodiments.

[0071] Figure 2G According to various embodiments Figure 2G Top perspective view of base 210.

[0072] According to various embodiments, the input assembly 200 may include (for example, further include) an anti-rotation device 250 configured to prevent the cap 220 from rotating relative to the base 210 (for example, about the connecting shaft 280).

[0073] For example, refer to Figure 2F and Figure 2G The cap receiving portion 211 of the base 210 may include an anti-rotation fitting element 251. As shown, the anti-rotation fitting element 251 may include one or more grooves 253 (or channels or slots) located on the outer surface (e.g., the outward-facing side surface) of the cap receiving portion 211 (e.g., a shaft) of the base 210. As an example, such as Figure 2F and Figure 2G As shown, each groove 253 can be tapered and oriented in a manner that widens at the free end region (e.g., upper region) of the cap receiving portion 211 (e.g., shaft) of the base 210. Therefore, each groove 253 can be a V-shaped (e.g., substantially V-shaped or U-shaped) groove 253 having an opening leading to the groove 253 at the free end region of the cap receiving portion 211 (e.g., shaft) of the base 210, and tapering (e.g., becoming narrower) at the bottom end region of the cap receiving portion 211 (e.g., shaft) of the base 210. Furthermore, according to various embodiments, the anti-rotation mating element 251 may include at least two misaligned (e.g., not directly opposite each other) grooves 253. For example, Figure 2F and Figure 2G A first groove 253a is shown at a first segment (e.g., a vertical segment) on the side of the cap receiving portion 211 of the base 210, and a second groove 253b is shown at a second segment on the side of the cap receiving portion 211 of the base 210. As shown, the second segment (and the second groove 253b) may be adjacent to the first segment (and the first groove 253a), but not directly opposite it. Furthermore, the second segment may, but is not limited to, be opposite to the movable member 230 (and / or along the displacement axis 282 of the movable member 230). This misaligned positioning of the first groove 253a and the second groove 253b of the anti-rotation fitting element 251 ensures that when the complementary anti-rotation fitting element 252 of the cap 220 (see below) is described later... Figure 2D and Figure 2E When engaged with the anti-rotation fitting element 251 of the base 210, the cap 220 of the input assembly 200 will be correctly oriented relative to the base 210. It is conceivable that in other embodiments, the anti-rotation fitting element 251 may comprise only a single groove 253.

[0074] As an example, such as Figure 2G Furthermore, the anti-rotation fitting element 251 may additionally include a third (or additional) groove 253c, which is disposed at a third (or additional) segment on the side of the cap receiving portion 211 of the base 210. The third segment (and the third groove 253c) may be adjacent to the second segment (and the second groove 253b), but not directly opposite it. However, as an example, such as Figure 2F and Figure 2G As shown, the third segment (and the third groove 253c) can be directly opposite the first segment (and the first groove 253a).

[0075] Return to reference Figure 2D and Figure 2E, the connecting portion 221 of the cap 220 may include complementary anti-rotation mating elements 252. As shown in the figure, the complementary anti-rotation mating elements 252 may include one or more tongue-like protrusions 254, which are located on the inner surface (e.g., the inward surface of the side wall) of the connecting portion 221 (e.g., the sleeve) of the cap 220. The number of the one or more tongue-like protrusions 254 may correspond to (in other words, may be equal to) the number of the one or more grooves 253 (i.e., the anti-rotation mating elements 251). The one or more tongue-like protrusions 254 may be configured to slidably engage (i.e., fit or insert into) the one or more grooves 253 (i.e., the anti-rotation mating elements 251) of the cap receiving portion 211 of the cap 220. In other words, the one or more tongue-like protrusions 254 and the one or more grooves 253 may be configured to slidably cooperate with each other. Specifically, the shape of each tongue-like protrusion 254 may correspond to (e.g., match) the shape of the corresponding (or respective) groove 253 (the tongue-like protrusion 254 may be configured to slidably cooperate with it). Therefore, when the groove 253 is a V-shaped groove, the tongue-like protrusion 254 may be a V-shaped tongue-like protrusion (i.e., oriented in the same direction as the V-shaped groove so as to be inserted into the V-shaped groove).

[0076] Therefore, according to various embodiments, the anti-rotation mating element 251 (e.g., the groove 253) of the base 210 and the complementary anti-rotation mating element 252 (e.g., the tongue-like protrusion 254) of the cap 220 may be configured to perform tongue-and-groove mutual cooperation by tongue-and-groove engagement to prevent the cap 220 from rotating relative to the base 210 (i.e., when the connecting portion 221 of the cap 220 is fully connected to the cap receiving portion 211 of the base 210).

[0077] It is conceivable that in other embodiments, the anti-rotation mating element 251 may include one or more tongue-like protrusions 254 located at the cap receiving portion 211 of the base 210, while the complementary anti-rotation mating element 252 may include one or more corresponding grooves 253 at the connecting portion 221 of the cap 220.

[0078] Figure 2H of (i) and Figure 2H Figures (i) and (ii) respectively show a side view and a bottom perspective view of a first variant cap 220a for the input assembly 200 according to various embodiments.

[0079] Figure 2I of (i) and Figure 2I Figures (i) and (ii) respectively show a side view and a bottom perspective view of a second variant cap 220b for the input assembly 200 according to various embodiments.

[0080] Figure 2JThis is a perspective view of a controller 2000 according to various embodiments, the controller 2000 having a pair of input assemblies 200, and adjacent to the controller 2000... Figure 2H A pair of first variant caps 220a and Figure 2I A pair of second variant caps 220b.

[0081] According to various embodiments, the cap 220 (hereinafter referred to as "preset cap" 220 as described above) can be interchanged with a first variant cap 220a or a second variant cap 220b. That is, the preset cap 220 can be removed (or detached) from the base 210 of the input assembly 200, and the first variant cap 220a or the second variant cap 220b can be detachably coupled to the base 210 of the input assembly 200.

[0082] Therefore, according to various embodiments, the connecting portions 221a, 221b of each of the first variant cap 220a or the second variant cap 220b can be configured similarly or identically to the preset cap 220. For example, the connecting portions 221a, 221b of each of the first variant cap 220a or the second variant cap 220b may include or may be in the form of a sleeve having the same inner diameter as the sleeve (i.e., connecting portion 221) of the preset cap 220.

[0083] However, reference Figure 2H The difference between the first modified cap 220a and the preset cap 220 is that the sleeve (i.e., the connecting portion 221a) of the first modified cap 220a can be longer in length (or taller in height) than the sleeve (i.e., the connecting portion 221a) of the preset cap 220. Furthermore, as an example, such as Figure 2H As shown, the first variant cap 220a differs from the default cap 220 in that the shape and / or size of the head 223a (and the anti-slip layer 224a on the head 223a) of the first variant cap 220a may differ from the head 223 (and the anti-slip layer 224 on the head 223a) of the default cap 220. For example, the head 223a (and the anti-slip layer 224a) of the first variant cap 220a may have a flat or recessed (e.g., concave) upper surface compared to the concave upper surface (and the anti-slip layer 224 on the head 223) of the default cap 220. Furthermore, the head 223a (and the anti-slip layer 224a) of the first variant cap 220a may have a larger diameter than the head 223 (and the anti-slip layer 224 on the head 223a) of the default cap 220.

[0084] For another example, see reference Figure 2IThe head 223b (and the anti-slip layer 224b on the head 223b) of the second variant cap 220b can have a smaller diameter than the head 223 (and the anti-slip layer 224 on the head 223) of the preset cap 220 (or the first variant cap 220a).

[0085] In addition, the second variant cap 220b differs from the preset cap 220 in that the sleeve (i.e., the connecting part 221b) of the second variant cap 220b can be shorter in length (or shorter in height) than the sleeve of the preset cap 220 (or the first variant cap 220a).

[0086] Therefore, the various embodiments described herein can provide an input assembly for a controller that provides an replaceable cap feature without requiring a magnet and / or magnetic elements to secure the cap to the base of the input assembly.

[0087] Therefore, various embodiments can provide a universal input combination that is compatible with various controllers (e.g., game controllers) that utilize various types of switches.

[0088] Furthermore, by eliminating the need for magnetic components such as metals to construct the input assembly, the manufacturing of the input assembly may be cost-effective.

[0089] Although the invention has been specifically shown and described with reference to specific embodiments, those skilled in the art to which this application pertains will understand that various changes, modifications, and alterations in form and detail may be made therein without departing from the scope of the invention as defined by the appended claims. Therefore, the scope of the invention is indicated by the appended claims and is thus intended to cover all changes falling within the meaning and scope of equivalents of the claims.
