Description

Game controller and its joystick assembly Technical Field

[0001] This invention relates to the field of game controller technology, and in particular to a game controller and its joystick assembly. Background Technology

[0002] Game controllers, a common accessory for video game devices, allow users to control virtual objects by manipulating their joysticks, buttons, and other components. Game controllers typically contain elastic elements to allow the joysticks to return to their original position after movement. The deformation properties of these elastic elements directly affect the feel of the joystick. For example, a higher elastic modulus or initial compression of the element results in greater resistance to joystick movement, meaning a stiffer feel; conversely, a lower elastic modulus or initial compression results in less resistance to joystick movement, meaning a softer feel.

[0003] In related technologies, the operating feel of the joystick on the same game controller is generally relatively fixed. Users need to replace the entire joystick assembly or the game controller to change the joystick's swing feel, which means that the ease of use needs to be improved. Summary of the Invention

[0004] Therefore, it is necessary to provide a game controller and its joystick assembly.

[0005] A joystick assembly, comprising:

[0006] A lever base includes a base body and a rocker arm. The rocker arm includes an outer rod, an inner rod, and an elastic element. The inner rod passes through the outer rod and extends out of the end of the outer rod away from the base body. The elastic element is disposed in the base body and abuts against the inner rod.

[0007] A rod cover, having an adjustment hole at one end opposite to the base, wherein the outer rod extends into the adjustment hole and is confined within the rod cover; and

[0008] An adjusting member is housed in the adjusting hole and connected to the rod cover. The adjusting member is driven to move relative to the rod cover and drive the inner rod to move relative to the outer rod to squeeze the elastic member, thereby adjusting the deformation of the elastic member.

[0009] A game controller includes a housing and a joystick assembly as described in any of the above claims, the joystick assembly being disposed within the housing. Attached Figure Description

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Referring to Figures 1 and 2, this application discloses a joystick assembly 10 for a game controller. During use, the operator can control virtual objects through the joystick assembly 10.

[0024] The rocker arm assembly 10 includes a rod base 100, a rod cover 200, and an adjusting member 300. The rod base 100 includes a seat 110 and a rocker arm 120. The seat 110 is generally a hollow rectangular box shape, providing rigid support for the entire structure. Referring to Figures 3 and 4, the rocker arm 120 includes an outer rod 121, an inner rod 123, and an elastic member 125. The inner rod 123 passes through the outer rod 121 and extends beyond the end of the outer rod 121 away from the seat 110. The outer rod 121 is generally a hollow cylinder, and the inner rod 123 is also generally cylindrical. The elastic member 125 is disposed within the seat 110 and abuts against the inner rod 123; the elastic member 125 can be a spring. During the swinging of the inner rod 123 and outer rod 121 of the rocker arm 120 relative to the seat 110, the elastic element 125 is compressed and deformed, generating a restoring force. After the operator releases the rocker arm 120, the elastic element 125 can drive the outer rod 121 and inner rod 123 to return to their original positions.

[0025] The rod cover 200 has an adjustment hole 200a at one end opposite to the seat 110. The outer rod 121 extends into the adjustment hole 200a and is confined within the rod cover 200. The adjustment member 300 is housed in the adjustment hole 200a and connected to the rod cover 200. The adjustment member 300 is driven to move relative to the rod cover 200 and drives the inner rod 123 to move relative to the outer rod 121, thereby compressing the elastic member 125 and adjusting the deformation of the elastic member 125.

[0026] Specifically, the rod cover 200 may have a cover body 210 and a protruding ring 220 protruding from the cover body 210 along the axial direction of the rocker arm 120. The cover body 210 is generally spherical, and the protruding ring 220 is connected to the end of the cover body 210 opposite to the base body 110, and the cover body 210 protrudes outward toward the side where the protruding ring 220 is located. The protruding ring 220 is generally cylindrical and has an adjustment hole 200a. The width of the cover body 210 is greater than the width of the protruding ring 220 and the base body 110. For example, the projection of the cover body 210 along the axial direction of the rocker arm 120 can completely cover the base body 110. The cover body 210 and the base body 110 may be spaced apart axially from the rocker arm 120 to provide space for the swing of the cover body 210 relative to the base body 110. After the joystick assembly 10 is assembled into the housing of the game controller, the protruding ring 220 passes through the mounting hole of the housing. The mounting hole of the housing can provide sufficient space for the protruding ring 220 and the outer rod 121 to swing relative to the housing. The cover 210 can be exposed from the mounting hole of the housing but covers the seat 110 to prevent dust and other foreign objects from entering the seat 110 from the mounting hole.

[0027] Referring to Figures 3 and 5, in some embodiments, the convex ring 220 has slots 200b on opposite sides for inserting the rod cap 40, so that the rod cap 40 is detachably connected to the rod cover 200 and covers the adjustment hole 200a. Exemplarily, the rod cap 40 may include a cap top 41 and an extension tube 43 connected to the cap top 41. The width of the cap top 41 is greater than the width of the extension tube 43. The extension tube 43 is cylindrical and has two opposing, deformable engaging portions 431. The engaging portions 431 have a cantilever beam structure and correspond one-to-one with the two slots 200b. The user can align the two engaging portions 431 with the two slots 200b and insert the extension tube 43 into the rod cap 40. The engaging portions 431 engage with the slots 200b of the rod cap 40, thereby achieving a detachable connection between the rod cap 40 and the rod cover 200. When a user needs to replace the pole cap 40, such as by replacing it with a pole cap 40 of different heights, the pole cap 40 can be removed from the pole cover 200 and a new pole cap 40 can be assembled onto the pole cover 200 to obtain a different operating feel and improve the convenience of use.

[0028] Furthermore, referring to Figures 3 and 4, the end of the convex ring 220 facing away from the seat 110 may also have a mating structure 221, which is used to align with the alignment structure 411 of the rod cap 40. Exemplarily, in the embodiment shown in Figures 3 and 4, the mating structure 221 consists of two protrusions extending from the end face of the convex ring 220. The line connecting the centers of the two protrusions can pass through the center of the convex ring 220, meaning the centers of the two protrusions can be distributed along a diameter of the convex ring 220. The side of the cap top 41 facing the seat 110 may be provided with the alignment structure 411, for example, two alignment grooves, which correspond one-to-one with the two mating structures 221. After the rod cap 40 is engaged with the rod cover 200, the two mating structures 221 are housed in the two alignment grooves in a one-to-one correspondence, thereby improving the alignment accuracy between the rod cap 40 and the rod cover 200 and preventing the rod cap 40 from rotating relative to the rod cover 200 around the axis of the rocker arm 120, thus improving the connection stability between the rod cap 40 and the rod cover 200. In other embodiments, the mating structure 221 can be a groove, and the alignment structure 411 can be a protrusion corresponding to the mating structure 221. The engagement of the mating structure 221 and the alignment structure 411 can also improve the alignment accuracy between the rod cap 40 and the rod cover 200 and prevent the rod cap 40 from rotating relative to the rod cover 200 around the axis of the rocker arm 120, thus improving the connection stability between the rod cap 40 and the rod cover 200.

[0029] In some embodiments, the rocker arm assembly 10 may further include a protective sleeve 500, which has suitable rigidity, such as a rigid plastic sleeve or a metal sleeve, with the plastic having a Shore hardness of 70D or higher. The protective sleeve 500 is fitted over the extension tube 43 and can be partially embedded in the cap 41, that is, the protective sleeve 500 can be fitted over the convex ring 220 and located between the cover 210 and the cap 41. Due to the presence of the deformable engaging portion 431, the circumferential direction of the extension tube 43 is not a complete cylindrical surface. During the swinging of the rocker arm 120, if the extension tube 43 directly contacts the wall of the mounting hole of the outer casing, the gaps on both sides of the engaging portion 431 will cause vibration or jamming upon impact, resulting in the rocker arm 120 rotating unevenly relative to the outer casing. By adopting the protective sleeve 500 of this application, the circumferential outer wall of the protective sleeve 500 can form a complete cylindrical surface, which can avoid the above-mentioned problems when the rocker arm assembly 10 collides with the housing, and improve the smoothness of the rotation of the rocker arm 120. On the other hand, when the operator operates the rocker arm 120 to swing through the rod cap 40, the protective sleeve 500 can contact the hole wall of the mounting hole of the housing. The protective sleeve 500, made of hard plastic or hardware (such as stainless steel), can also prevent the extension tube 43 from rigidly colliding with the housing and being easily worn, thereby improving the service life of the rocker arm assembly 10.

[0030] Referring to Figure 5, the rocker arm 120 may also include a support 127 with an axially oriented shaft hole 127a, and an outer rod 121 with an axially oriented through hole 121a. The support 127 is axially located at the end of the outer rod 121 away from the rod cover 200 and at least partially passes through the through hole 121a of the outer rod 121. The inner rod 123 includes an integrally formed rod body 1231 and a limiting part 1233, the width of which is greater than the width of the rod body 1231. The rod body 1231 passing through the through hole 121a and located on the side of the limiting part 1233 opposite to the support 127 protrudes from the end of the outer rod 121 opposite to the support 127, while the rod body 1231 on the opposite side of the limiting part 1233 passes through the shaft hole 127a of the support 127. The limiting part 1233 can abut against the wall of the through hole 121a to limit the movement range of the inner rod 123 in the through hole 121a. The elastic element 125 is sleeved on the rod body 1231 and the support 127, and its two ends abut against the support 127 and the limiting part 1233 respectively, thereby realizing the elastic floating connection of the outer rod 121, the inner rod 123 and the support 127. When the outer rod 121 is driven to swing relative to the seat body 110, the cooperation between the rod body 1231 and the shaft hole 127a, and the cooperation between the elastic element 125 and the support 127, keep the support 127 in contact with the seat body 110, ensuring the stability of the rocker arm 120 swing. The end of the support 127 that contacts the seat body 110 can be machined into an arc surface to reduce the contact area between the support 127 and the seat body 110 and ensure the smoothness of the swing of the support 127 relative to the seat body 110.

[0031] Referring again to Figure 3, the joystick 120 may further include an upper rocker arm 1281 and a lower rocker arm 1283 arranged crosswise within the base 110. For example, the upper rocker arm 1281 and the lower rocker arm 1283 may be orthogonally arranged, meaning their rotation axes relative to the base 110 may be perpendicular to each other. An outer rod 121 passes through the upper rocker arm 1281 and the lower rocker arm 1283. For example, the rod cover 200, the upper rocker arm 1281, the lower rocker arm 1283, and the support 127 may be arranged sequentially along the axial direction of the joystick 120. Referring to Figures 4 and 5, the rod holder 100 may include two turntables 130 capable of rotating relative to the base 110. Each turntable 130 is fixed with a sensing element 140, which may be a magnet. The sensing element 140 may correspond to a sensing element on the circuit board of the game controller. The sensing element may be a Hall sensor. The upper rocker arm 1281 and the lower rocker arm 1283 are respectively fitted with a turntable 130. When the outer rod 121 swings, the upper rocker arm 1281 drives the corresponding turntable 130 and the sensing element 140 to swing relative to the base 110, or the lower rocker arm 1283 drives the corresponding turntable 130 and the sensing element 140 to swing relative to the base 110. This achieves the relative movement of the sensing element 140 and the sensing element to generate a detection signal, thereby enabling the operation of virtual objects in the game.

[0032] Referring again to Figures 2 and 3, the adjusting member 300 has a tool groove 300a on the side opposite to the base 110. The tool groove 300a is used to insert a tool to drive the adjusting member 300 to move relative to the rod cover 200. In some embodiments, the adjusting member 300 is a threaded post with substantially the same width at both ends, which is threadedly connected to the rod cover 200. For example, the adjusting member 300 has a first end 310 and a second end 320 opposite each other in the axial extension direction of the joystick 120. The first end 310 is further away from the base 110 than the second end 320. The first end 310 has a tool groove 300a, and the width of the first end 310 is not greater than the width of the second end 320. This structure of the adjusting member 300 makes it easier to process into a general-purpose part. For example, some common standard thread sizes can be used, and general-purpose equipment can be used to achieve rapid processing and forming of the adjusting member 300, reducing the processing cost of the adjusting member 300 and the rod cover 200, meeting the requirements of mass production in industry, thereby reducing the cost of the joystick assembly 10 and the game controller.

[0033] The tool slot 300a can be a Phillips head slot to accommodate Phillips head screwdrivers, allowing the user to easily turn the adjusting member 300 through the tool slot 300a. This causes the adjusting member 300 to move axially along the rocker arm 120 within the adjusting hole 200a, driving the inner rod 123 to move relative to the outer rod 121 towards or away from the support 127. This, in turn, changes the deformation of the elastic member 125, altering the operating feel of the rocker arm 120. For example, when the adjusting member 300 moves axially along the rocker arm 120 within the adjusting hole 200a, driving the inner rod 123 towards the support 127 relative to the outer rod 121, the compression of the elastic member 125 increases. As is well known, the greater the compression of the elastic member 125, the greater the resistance to further deformation. This manifests in the operator's feel as greater resistance and a stiffer feel when the rocker arm 120 is oscillating. Conversely, when the adjusting member 300 moves along the axial direction of the rocker arm 120 within the adjusting hole 200a, driving the inner rod 123 to move away from the support 127 relative to the outer rod 121, the compression of the elastic member 125 decreases, the swing resistance of the rocker arm 120 decreases, and the feel becomes softer.

[0034] In other words, when a user needs to adjust the swing feel of the joystick 120, the joystick cap 40 can be removed from the joystick cover 200. Using the tool and tool slot 300a, the adjusting member 300 can be moved axially within the adjusting hole 200a along the joystick 120, thereby adjusting the deformation of the elastic member 125 and adjusting the operating feel of the joystick 120. After adjustment, the joystick cap 40 can be locked back into the joystick cover 200 to allow the joystick 120 to function normally, thus improving the convenience of feel adjustment. Because the adjusting member 300 can be hidden within the space enclosed by the joystick cap 40 and the joystick cover 200, compared to structures where the adjustment structure is exposed to the outside, the problem of the operator accidentally touching the adjusting member 300 can be avoided.

[0035] It is understandable that the tool slot 300a can also be a slotted slot or an internal hexagonal slot, etc., which can be used to adapt to the corresponding screwdriver. The connection between the adjusting member 300 and the convex ring 220 is not limited to a threaded connection. It can also be achieved by the cooperation of the convex point and the irregular groove or other structures to move the adjusting member 300 relative to the rod cover 200. The elastic member 125 supports the inner rod 123 to keep the convex point stably held in some specific positions of the rod cover 200, thereby realizing the adjustment of the swing feel of the joystick 120.

[0036] Referring again to Figures 3 and 4, and in conjunction with Figure 6, the adjustment hole 200a is countersunk, and the outer rod 121 protrudes from the bottom surface of the adjustment hole 200a. The outer rod 121 has a groove 121b extending circumferentially and exposed within the adjustment hole 200a. A through hole 200c is formed on the bottom surface of the adjustment hole 200a, extending to the side of the rod cover 200 facing the base 110. The outer rod 121 passes through the through hole 200c. The rocker arm assembly 10 includes an open retaining ring 600, which is embedded in the groove 121b, and the width of the retaining ring is greater than the width of the through hole 200c. Referring to Figure 3, the outer rod 121 may include a body 1211 and a boss 1213 protruding from the outer surface of the body 1211. The body 1211 passes through the through hole 200c and has a slot 121b and a through hole 121a for the inner rod 123 to pass through. The slot 121b and the boss 1213 are spaced apart along the axial direction of the rocker arm 120. The width of the outer rod 121 at the boss 1213 is greater than the width of the through hole 200c, so as to limit the movement of the rod cover 200 relative to the outer rod 121 by the open retaining ring 600 and the boss 1213.

[0037] During the assembly of the rocker arm 120 and the rod cover 200, the rod base 100 can be pre-assembled into an independent component. Then, the outer rod 121 is inserted into the adjustment hole 200a through the through hole 200c from one end of the rod cover 200 away from the protruding ring 220 until the boss 1213 abuts against the end face of the through hole 200c. At this time, the ends of the outer rod 121 and the inner rod 123 away from the seat body 110 protrude into the adjustment hole 200a. The open retaining ring 600 is then fitted onto the outer rod 121 from the side of the adjustment hole 200a away from the seat body 110, and after being deformed, it is inserted into the retaining groove 121b, thus limiting the position of the outer rod 121 in the rod cover 200. That is, when the rod cover 200 moves away from the seat body 110, the open retaining ring 600 restricts the movement of the rod cover 200; when the rod cover 200 moves closer to the seat body 110, the boss 1213 restricts the movement of the rod cover 200. By designing the assembly tolerances of the outer rod 121, through hole 200c, slot 121b, boss 1213, and open retaining ring 600, the outer rod 121 can be stably confined within the rod cover 200, making the rod cover 200 and the outer rod 121 nearly a single unit. This prevents the outer rod 121 from easily shifting or shaking relative to the rod cover 200, thus avoiding abnormal noise during operation.

[0038] Specifically, referring to Figures 3 and 5, in some embodiments, the base 110 of the rocker assembly 10 is also fixedly connected to a button 700. When the operator presses down the rod cap 40 along the axis of the rocker 120, the rod cover 200 presses against the boss 1213, causing the outer rod 121 to move towards the support 127. The outer rod 121 can trigger the corresponding function by pressing down the button 700 through the lower rocker arm 1283.

[0039] For example, referring to FIG7, the cross-section of the body 1211 can be a rounded rectangle, having a first plane 1215 and a second plane 1217 arranged opposite to each other and parallel to each other, and a first arc surface 1218 and a second arc surface 1219 connecting the first plane 1215 and the second plane 1217. The first plane 1215 and the second plane 1217 correspond to two parallel straight sides of the rounded rectangle in cross-section, while the first arc surface 1218 and the second arc surface 1219 correspond to two arc-shaped sides. A boss 1213 is provided on the first plane 1215 side and the second plane 1217 side, respectively. The cross-section of the boss 1213 can be arc-shaped, and its width is smaller than the width of the first plane 1215 and the second plane 1217. The cross-sectional profile of the perforation 200c matches the cross-sectional profile of the body 1211, that is, the cross-section of the perforation 200c is also a rounded rectangle, to limit the rotation of the rod cover 200 relative to the outer rod 121.

[0040] In this embodiment, the outer rod 121 has a relatively simple structure and is easy to manufacture, and its assembly with the rod cover 200 is also relatively easy. For example, the through hole 200c of the rod cover 200 and the body 1211 of the outer rod 121 can adopt a clearance fit or a transition fit to achieve convenient assembly of the outer rod 121 and the rod cover 200, improving assembly efficiency. Since the outer rod 121 usually needs to have the function of pressing the trigger button 700, the assembly and fixation of the rod cover 200 and the outer rod 121 is more conducive to operating the trigger button 700. Compared with the interference fit between the outer rod 121 and the through hole 200c, this assembly method of the present application is easier to assemble and has higher assembly efficiency.

[0041] The rocker arm assembly 10 includes a rod base 100, a rod cover 200, and an adjusting member 300. The rod base 100 includes a seat 110 and a rocker arm 120. The rocker arm 120 includes an outer rod 121, an inner rod 123, and an elastic member 125. The inner rod 123 passes through the outer rod 121 and extends out of the end of the outer rod 121 away from the seat 110. The elastic member 125 is disposed in the seat 110 and abuts against the inner rod 123. The rod cover 200 has an adjusting hole 200a at the end opposite to the seat 110. The outer rod 121 extends into the adjusting hole 200a and is confined within the rod cover 200. The adjusting member 300 is accommodated in the adjusting hole 200a and connected to the rod cover 200. The adjusting member 300 is driven to move relative to the rod cover 200 and drives the inner rod 123 to move relative to the outer rod 121, thereby compressing the elastic member 125 and adjusting the deformation of the elastic member 125. The rod cover 200 can be used to detachably connect the rod cap 40. When the user needs to adjust the swing feel of the joystick 120, the rod cap 40 can be removed to expose the adjustment member 300. The adjustment member 300 drives the inner rod 123 to move relative to the outer rod 121 to adjust the deformation of the elastic member 125, thereby changing the swing feel of the joystick 120 and improving the convenience of use.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
