Description

Foot game controller TECHNICAL FIELD

[0001] The present application relates to the technical field of game control, for example to a foot game controller. BACKGROUND

[0002] Various types of game controllers have emerged on the market, including commonly used mouse keyboards, arcade-style game joysticks, game console handles, mobile device-specific controllers, and customized versions optimized for specific games, meeting the diverse needs of different players, such as professional steering wheels designed for racing games, flight sticks for flight simulation games, etc.

[0003] However, long-term holding and operating game controllers can cause hand muscles to be in a state of tension for a long time. Especially in intense competitive games, players need to press keys frequently and move joysticks quickly, which can easily cause fatigue due to frequent contraction and relaxation of hand muscles. For example, when playing action games for several hours in a row, the player's hands may feel sore and stiff, affecting subsequent game experience. At the same time, it is not convenient for players who have difficulty operating handheld game controllers (or have disabilities in their hands) to use them.

[0004] Therefore, the prior art is not sufficient to meet the needs of users.

Conversely, a rear force is applied to the pedal. If a force is applied to the left part of the pedal, the pedal does not move relative to the six-end shaft, but the pedal can drive the six-end shaft to rotate left relative to the lower support frame around the front and rear shafts. The first potentiometer measures the angle of rotation of the six-end shaft relative to the lower support frame, and after the main control board receives the measured angle data, the controlled object in the game is controlled to move left. Conversely, a right force is applied to the pedal. That is, the controlled object in the game can be moved by controlling the pedal. Of course, the player can also customize the function of stepping on the pedal, for example, applying a forward force to the pedal to realize running, jumping and other actions. It is suitable for players who need to operate more keys, especially for players who have difficulty using both hands or people with hand disabilities.

[0057] By setting the first damping device or the second damping device, the elastic coefficient of the force applied in the front-rear direction or the left-right direction is changed, so that the player has a clear speed difference when controlling the movement of the controlled object in the game, and the player has a richer game experience.

[0102] The compression spring force rod 403 abuts against the other end of the first follower 411, the compression spring force rod 403 being partially sleeved in the first sleeve 405 and extending to the outside of the first sleeve 405 at one end, and the other end of the first follower 411 being used to abut against the compression spring force rod 403 to realize force conduction in the axial direction of the first sleeve 405, and when the axial external force of the compression spring force rod 403 in the direction towards the third spring 410 is greater than the elastic force of the third spring 410 acting on the first follower 411, the compression spring force rod 403 can drive the first follower 411 to slide in the axial direction of the first sleeve 405 to the fourth position K to compress the third spring 410, as shown in the state change from FIG. 20 to FIG. 21.

[0103] It should be understood that when the first follower 411 slides in the axial direction of the first sleeve 405 to the fourth position K, that is, the axial external force of the compression spring force rod 403 in the direction towards the third spring 410 is greater than the elastic force of the third spring 410 acting on the first follower 411 until the force is balanced. In this way, the user can apply the adjustable elastic compression spring device 4 to different pushing forces required by corresponding application members, to meet the use needs of different force scenarios.

[0104] Specifically, the third spring 410 can be pre-compressed or released to change the elastic force of the third spring 410 acting on the first follower 411 when the elastic force pre-adjusting assembly E is controlled.

[0105] In actual use, the third spring 410 is pre-compressed or released by controlling the elastic force pre-adjusting assembly E. Specifically, the elastic force pre-adjusting assembly E includes a first moving part 407, a first steel ball 408, and a first main shaft 406. The end of the first main shaft 406 outwardly has a hexagonal hole for a hexagonal screwdriver to be inserted. A user can control the rotation of the first main shaft 406 by twisting the screwdriver. When the first main shaft 406 rotates forward, the first moving part 407 sleeved on the outer periphery of the first main shaft 406 and screw-connected with the first main shaft 406 moves axially downward relative to the first main shaft 406, as shown in the state of FIG. 20 from the state of FIG. 19. It should be noted that, since the two first guide parts 422 of the first moving part 407 respectively abut against the two first guide grooves 4051 on the first sleeve 405, the position of the first sleeve 405 abutting against the first guide part 422 of the first moving part 407 has a limiting groove, i.e., the first guide groove 4051. The limiting groove, i.e., the first guide groove 4051, is located in the axial direction of the first sleeve 405. When the first moving part 407 moves axially along the first sleeve 405, the first guide part 422 fixed on the first moving part 407 is limited by the first guide groove 4051. Therefore, the first moving part 407 can only move axially upward or downward along the first sleeve 405.

[0106] In addition, since the lower surface of the first moving part 407 abuts against the top of the third spring 410, when the first main shaft 406 rotates forward, the first moving part 407 moves axially downward to compress the third spring 410, as shown in FIG. 20. The spring force generated by the compression of the third spring 410 is transmitted to the first follower 411 to form an elastic force on the compression spring force rod 403.

[0107] Conversely, when the first main shaft 406 rotates reversely, the first moving part 407 moves axially upward relative to the first main shaft 406, i.e., the state of the first moving part 407 and the third spring 410 changes from the state of FIG. 20 to the state of FIG. 19, to release the third spring 410, so that the elastic force of the third spring 410 acting on the first follower 411 and the compression spring force rod 403 becomes smaller.

[0108] For example, according to the elastic formula F=kx, where F is the elastic force, k is the elastic coefficient of the material, and x is the expansion amount of the spring deformation, i.e., the change in the height of the spring. In an adjustable elastic force adjusting device, k, i.e., the elastic coefficient, is determined by the material properties of the third spring 410 itself, so the elastic coefficient k is fixed, and the expansion amount x becomes larger and larger as the first moving part 407 moves axially downward along the first sleeve 405. Then, according to the elastic formula F=kx, it can be obtained that the elastic force F also presents an increasing trend as the first moving part 407 moves axially downward. Therefore, by controlling the forward rotation of the first main shaft 406 to make the first moving part 407 move axially downward further, the force of the third spring 410 on the first driven part 411 can be increased. Conversely, by controlling the reverse rotation of the first main shaft 406, the first moving part 407 can move axially upward to reduce the force of the third spring 410 on the first driven part 411. Therefore, the elastic force of the third spring 410 can be adjusted by controlling the first main shaft 406.

[0109] When not in use, i.e., under non-external force conditions, the third spring 410 makes the first driven part 411 located at the third position J in the first sleeve 405 as shown in FIG. 19, at which time the third spring 410 does not produce expansion deformation due to the compression spring force rod 403.

[0110] After the elastic force is pre-adjusted to a suitable elastic force, it is necessary to fix the elastic force of the adjustable elastic force device. Further, the elastic force pre-adjusting assembly E further comprises a first steel ball 408, and the first main shaft 406 cooperating with the first steel ball 408 has a first positioning groove 4061; the first steel ball 408 falls into the first positioning groove 4061 to limit the rotation of the first main shaft 406.

[0111] In use, the first main shaft 406 is twisted by an external force or a device (such as a screwdriver), and after the first main shaft 406 is twisted to make the first moving part 407 move downward to compress the third spring 410 to generate the required elastic force, the first main shaft 406 is twisted to align the first positioning groove 4061 with the first steel ball 408, so that the first steel ball 408 can fall into the first positioning groove 4061 to prevent the first main shaft 406 from further rotating, thereby preventing the first moving part 407 from further moving.

[0112] The first steel ball 408 is arranged in a first end cover 417 assembled on the top of the first sleeve 405. Specifically, the first end cover 417 has a first assembly area 4171 which is a groove recessed inward on the surface of the first end cover 417, the top of the first assembly area 4171 has an opening, and the bottom of the first assembly area 4171 has a first channel 4172 which communicates with the hollow part C. In assembly, the bottom of the first main shaft 406 extends into the hollow part C of the first sleeve 405 from the first channel 4172, and after the first main shaft 406 passes through the first channel 4172, the first adjusting part 4062 is exposed outside the opening, i.e. the first adjusting part 4062 of the first main shaft 406 is exposed outside the first end cover 417, so that the user can perform a twisting operation on the first adjusting part 4062 of the first main shaft 406.

[0113] The first steel ball 408 is specifically arranged on the inner wall of the first channel 4172, and in this embodiment, the first steel ball 408 is a positioning ball with a spherical structure, has a corresponding mounting groove on the inner part of the first channel 4172, and is partially accommodated in the mounting groove and partially exposed on the inner wall surface of the first channel 4172. When the first main shaft 406 to be accommodated in the first channel 4172 is twisted to align the first positioning groove 4061 with the positioning ball, the positioning ball falls into the first positioning groove 4061, and the radial radial spring force generated by the abutment of the second spring 409 against the positioning ball is used to achieve the position positioning of the first main shaft 406, avoiding the position movement of the first main shaft 406 without external force.

[0114] The first assembly area 4171 has a first thrust bearing 412, the upper surface of the first thrust bearing 412 abuts against the lower end of the fourth spring, and the lower surface of the first thrust bearing 412 abuts against the bottom of the inner surface of the first assembly area 4171. When the first main shaft 406 is rotated by external force, the first thrust bearing 412 can constrain the axial rotation of the first main shaft 406 and avoid deviation.

[0115] The fourth spring 418 is arranged between the top of the first thrust bearing 412 and below the first adjusting part 4062, so that when the adjustable elastic adjusting device needs to be disassembled, the fourth spring 418 can be compressed by pressing the first adjusting part 4062 from the axial direction to expose the third circlip 419 from the lower groove of the first end cover 417, and then the third circlip 419 can be removed by using a tool such as a circlip dismounting tool, so as to further realize the dismounting of the elastic pre-adjusting assembly E and the first end cover 417. In addition, the fourth spring 418 can also push against the first adjusting part 4062 to avoid the axial downward movement of the first main shaft 406 under the action of no external force.

[0116] The first end cover 417 and the first moving part 407 are provided with a third circlip 419 arranged on the outer periphery of the first main shaft 406, which is used to prevent the first main shaft 406 from moving axially upward. In summary, the third circlip 419 cooperates with the fourth spring 418 to constrain the first main shaft 406 at the top of the first sleeve 405, effectively avoiding the axial upward or downward movement of the first main shaft 406 in the first channel 4172 under the action of no external force.

[0117] The first sleeve 405 is provided with a first sub-sleeve 415, and the first sub-sleeve 415 is axially provided with a sliding channel 4153 for the axial reciprocating movement of the compression spring force rod 403. When the compression spring force rod 403 is under stress, the end of the compression spring force rod 403 moves axially repeatedly in the sliding channel 4153, and when entering the inside of the sliding channel 4153 of the first sub-sleeve 415, the compression spring force rod 403 can abut against the first driven part 411 to realize force transmission.

[0118] In use, when the part of the compression spring force rod 403 exposed outside the first sleeve 405 is under stress, the compression spring force rod 403 slides in the sliding channel 4153 along the axial direction until abutting against the first driven part 411, so that the first driven part 411 can press the third spring 410. The arrangement of the sliding channel 4153 can avoid the radial movement of the compression spring force rod 403 during sliding, thereby avoiding deviation.

[0119] The first sub-sleeve 415 comprises a split design of a first outer sleeve 4151 and a first inner sleeve 4152 combined together. The first outer sleeve 4151 is sleeved on the outer periphery of the first inner sleeve 4152. In this way, the first outer sleeve 4151 is used for axial positioning, and the first inner sleeve 4152 can be a linear bearing or a shaft sleeve. The first inner sleeve 4152 can be worn out after a long time of use, and the split design of the first outer sleeve 4151 and the first inner sleeve 4152 facilitates the replacement of the worn first inner sleeve 4152.

[0120] The first sleeve 405 has at least two sets of clamping components D on the inner bottom side, each set of the clamping components D includes a third gasket 4142 and a second circlip 4141; one set of the clamping components D is arranged above the first sub-sleeve 415 and defined as an upper clamping component 413, and the other set of the clamping components D is arranged below the sub-sleeve and defined as a lower clamping component 414; the upper clamping component 413 cooperates with the lower clamping component 414 to constrain the first sub-sleeve 415 on the inner bottom side of the first sleeve 405.

[0121] It should be understood that when the user steps on the pedal 201, the compression spring force rod 403 is moved in the slide 4153 under the action of external force, and the surface of the compression spring force rod 403 and the inner wall of the slide 4153 generate a certain friction force, so that the first sub-sleeve 415 moves axially with the axial movement of the compression spring force rod 403, and the upper clamping component 413 and the lower clamping component 414 constrain the first sub-sleeve 415 on the inner bottom side of the first sleeve 405, thereby effectively preventing the first sub-sleeve 415 from moving axially.

[0122] In addition, when the compression spring force rod 403 does not abut against the first follower 411, the first follower 411 has a downward movement tendency due to the extrusion of the first moving part 407 on the third spring 410, and the clamping component D can block the first follower 411 from moving further downward.

[0123] The first sleeve 405 has a third sealing ring 416 therein, the upper surface of the third sealing ring 416 abuts against the lower surface of the first sub-sleeve 415, and the lower surface of the third sealing ring 416 abuts against the upper surface of the lower clamping component 414. When the compression spring force rod 403 reciprocates in the slide 4153, the third sealing ring 416 can isolate the outside dust from entering the spring.

[0124] As shown in FIGS. 22-30, the torsion spring device 5 includes a second sleeve 501, a second main shaft 505, a second moving part 506, a fifth spring 509, a second follower 510, and a second driving part 520. The second moving part 506, the fifth spring 509, the second follower 510, and the second driving part 520 are arranged from top to bottom in the second hollow portion G of the second sleeve 501 and are sleeved on the outer periphery of the second main shaft 505 from top to bottom.

[0125] As shown in FIG. 24, the second sleeve 501 is a hollow structure with a second hollow portion G, which is open at both upper and lower ends, i.e. including an upper opening and a lower opening. Preferably, the second sleeve 501 adopts a cylindrical sleeve structure. In addition, the spring torque device of the present application needs to be assembled at a specific position, such as fixed on an assembly plate. In order to facilitate assembly, in some embodiments, the second sleeve 501 is designed as a stepped structure. Specifically, as shown in FIGS. 22 and 24, the second sleeve 501 is provided with an outwardly convex portion 5011 at the middle position, and both ends are small end portions. During assembly, the entire spring torque device is fixed and assembled by clamping the outwardly convex portion 5011 by a clamp structure. In order to ensure the strength of the entire spring torque device, the second sleeve 501 of the present application is preferably made of metal material, such as stainless steel, iron, copper, aluminum alloy, etc. In order to ensure the engagement force of the clamp when fixed, and ensure the stability of the installation, the outer surface of the outwardly convex portion 5011 is designed as an anti-skid tooth structure. Specifically, the outer surface of the outwardly convex portion 5011 is provided with an axial rack structure. In this way, during fixing, the clamp can be more closely matched with the rack structure.

[0126] As shown in FIG. 23, the second main shaft 505 is assembled and connected with the first limiting assembly F at the upper end of the second sleeve 501 to constrain the downward displacement of the second main shaft 505; the lower end of the second main shaft 505 is detachably connected with a fifth clamp spring 536, which is located below the second driving member 520 so that the second driving member 520 is at least partially located in the second sleeve 501.

[0127] As shown in FIG. 25, the second spindle 505 is in the form of a stepped distribution as a whole. It includes an upper portion 201, a middle portion, and a lower portion. The outer diameter of the upper portion, i.e., the second adjusting portion 5053, is greater than that of the middle portion, and the outer diameter of the middle portion is greater than that of the lower portion. Of course, this is not a limitation, and any suitable shape of the second spindle 505 is acceptable. As shown in FIG. 23, the first limiting assembly F includes a second end cover 502 having a stepped through hole, the upper end of which is larger than the lower end. The second adjusting portion 5053 of the second spindle 505 is arranged at the upper end portion of the stepped through hole, and the middle portion of the second spindle 505 extends downward after passing through the lower end portion of the through hole of the second end cover 502. The second end cover 502 is in the form of a stepped structure, and the size of the upper portion is greater than the size of the upper end opening of the second hollow portion G of the second sleeve 501. The lower portion of the second end cover 502 matches the shape and size of the second hollow portion G, so that the second end cover 502 is just clamped into the second hollow portion G and restricts the downward movement of the second spindle 505 in the axial direction. In order to ensure that the second spindle 505 and the second end cover 502 can be fixed together and prevent the second spindle 505 from falling upward, the first limiting assembly F further includes a seventh spring 535 and a fourth circlip 531. The fourth circlip 531 is detachably assembled with the second spindle 505, the seventh spring 535 is sleeved on the outer periphery of the second spindle 505 and located between the fourth circlip 531 and a second thrust bearing 532, the second thrust bearing 532 is sleeved on the second spindle 505 and abuts against the second end cover 502 at the upper end and abuts against the seventh spring 535 at the lower end. With this scheme, the seventh spring 535 can generate an axial downward force on the fourth circlip 531, thereby generating a downward force on the second spindle 505, ensuring stable assembly of the second spindle 505 and the second end cover 502, and preventing easy falling.

[0128] As shown in FIG. 29, which shows an assembly view of the second end cover 502 and the second spindle 505. In detail, the second end cover 502 has a second clamping hole 5021 radially, which has a sixth spring 533 and a second steel ball 534, and the outer side of the hole of the second spindle 505 matched with the second end cover 502 has a second positioning groove 5051. When assembled, the sixth spring 533 and the second steel ball 534 are both arranged in the second clamping hole 5021, and under the elastic force of the sixth spring 533, the second steel ball 534 is partially clamped in the second positioning groove 5051. In this way, the second steel ball 534 partially falls in the second positioning groove 5051 and partially in the second clamping hole 5021, so that the second steel ball 534 realizes the locking of the second spindle 505. That is, when not subjected to external force or the external force does not exceed the predetermined force, the second spindle 505 will not rotate. When the second spindle 505 is rotated by force, the second steel ball 534 is squeezed into the second clamping hole 5021 under the action of the second spindle 505, so that the second spindle 505 can continue to rotate to press the fifth spring 509 or release the fifth spring 509. When the external force is removed, the second steel ball 534 is reset to the second positioning groove 5051 under the action of the sixth spring 533, realizing the rotation locking of the second spindle 505. Of course, it should be clear that the torsional force generated by the fifth spring 509 is not enough to drive the second spindle 505 to break through the restraint of the sixth spring 533. It should be understood that in this scheme, along the circumference, the circumferential side of the second end cover 502 has a plurality of second positioning grooves 5051, and at different rotation angles, the second steel ball 534 can fall into different second positioning grooves 5051 to realize locking. Of course, in addition, the second steel ball 534 can also be a friction piece, which is in friction contact with the outer circumferential side of the second end cover 502 after assembly to generate a rotational constraint on the second spindle 505. Of course, in other embodiments, the sixth spring 533 and the second steel ball 534 can not be provided, but the outer circumferential side of the second end cover 502 and the second spindle 505 is in friction contact to resist the torsional force generated by the fifth spring 509, preventing rotation when there is no external force or the external force is not large enough.

[0129] As shown in FIG. 23 and FIG. 25, the second moving piece 506 is threadedly connected with the second main shaft 505 and is in constrained cooperation with the second sleeve 501 to realize axial reciprocating movement during rotation of the second main shaft 505. Specifically, the outer periphery of the upper half of the middle portion of the second main shaft 505 is provided with a second main shaft thread 5052. As shown in FIG. 30, the second moving piece 506 is provided with a third threaded hole 5061 in which an internal thread is arranged. During assembly, the third threaded hole 5061 of the second moving piece 506 is sleeved at the second main shaft thread 5052 to realize threaded connection. The second sleeve 501 is provided with a second guide groove hole 5012 arranged along the axial direction, and the outer periphery of the second moving piece 506 is detachably connected with a second guide piece 507 which is located at the second guide groove hole 5012 and is in abutting constraint in the circumferential direction, so that the second guide piece 507 can only move up and down along the second guide groove hole 5012. That is, the second main shaft 505, the second moving piece 506, the second guide piece 507, and the second guide groove hole 5012 of the second sleeve 501 constitute a threaded screw rod and slider structure. When the second main shaft 505 rotates, the second moving piece 506 produces axial reciprocating movement up and down due to the limiting effect of the second guide groove hole 5012 of the second sleeve 501 on the second guide piece 507. When the second moving piece 506 moves downward, the fifth spring 509 is further compressed, so that the elastic force of the fifth spring 509 becomes larger; when the second moving piece 506 moves upward, the fifth spring 509 is released, so that the elastic force of the fifth spring 509 becomes smaller. In addition, in order to prevent dust, impurities and the like from accumulating at the second guide groove hole 5012, a second housing 503 is sleeved outside the periphery of the region where the second guide groove hole 5012 is arranged.

[0130] As shown in FIG. 23, the two ends of the fifth spring 509 abut against the second moving piece 506 and the second driven piece 510 respectively to apply elastic force to the second moving piece 506 and the second driven piece 510. Specifically, in the technical solution, the fifth spring 509 is always in a compressed state, or just in a free state when the second moving piece 506 moves to the uppermost position and the second driven piece 510 is located at the lowermost position. That is, except for the case that the fifth spring 509 is in a free state when the second moving piece 506 moves to the uppermost position and the second driven piece 510 is located at the lowermost position, the fifth spring 509 is in a compressed state at any other position. The elastic force generated by the fifth spring 509 produces an upward force on the second moving piece 506 and a downward force on the second driven piece 510.

[0131] In the embodiment, the second follower 510 is in constrained cooperation with the second sleeve 501 to reciprocate along the axial direction when driven. That is, the second follower 510 can only reciprocate along the axial direction. In detail, as shown in FIG. 23, the outer side of the second follower 510 is detachably connected with a third guide 508, and the lower part of the second sleeve 501 is provided with a third guide slot hole 5013 arranged along the axial direction, the third guide 508 is located in the third guide slot hole 5013 and in circumferential abutment with the side wall forming the third guide slot hole 5013. In this way, the second follower 510 can only move along the axial direction when subjected to force. In addition, in order to prevent dust, impurities and the like from accumulating at the third guide slot hole 5013, a third shell 504 is sleeved on the outer periphery of the region where the third guide slot hole 5013 is arranged.

[0132] It needs to be clear that the second driver 520 and the second follower 510 are in transmission cooperation through a screw pair to achieve that when the second driver 520 is rotated along a first direction under external force, the second follower 510 is driven to move upward to compress the fifth spring 509 and after the external force is removed, the second follower 510 is reset along a second direction opposite to the first direction under the action of the fifth spring 509. Specifically, when the second driver 520 is rotated along the first direction (such as the left direction shown in FIG. 23) under force, the second driver 520 drives the second follower 510 to move axially away from the second driver 520, that is, the second follower 510 is driven to move upward, and the moving process further compresses the fifth spring 509. When the external force acting on the second driver 520 is removed, the fifth spring 509 will reset along the direction of restoring the elastic force, and the compression amount will decrease, that is, the fifth spring 509 will rebound, drive the second follower 510 to move downward, and when the second follower 510 moves downward, the second driver 520 is driven to rotate along the second direction and return to the initial state. When the second follower 510 moves downward, the second driver 520 is driven to rotate along the second direction due to the action of the screw pair of the second driver 520 and the second follower 510 until the fifth spring 509 is completely reset to the initial position. In this way, a torque stroke is achieved.

[0133] In addition, as shown in FIG. 23, the fifth clamping spring 536 is, for example, a clamping spring sheet, which is detachably clamped at the lower part of the second main shaft 505, and the upper end surface of the fifth clamping spring 536 is in abutment with the second driver 520 to generate axial constraint on the second driver 520, preventing the second driver 520 from being separated from the second main shaft 505 under the action of the elastic force generated by the fifth spring 509. In a specific embodiment, a third thrust bearing 537 is arranged between the second driver 520 and the fifth clamping spring 536, the upper end of the third thrust bearing 537 is in abutment with the second driver 520, and the lower end of the third thrust bearing 537 is in abutment with the fifth clamping spring 536.

[0134] As shown in FIG. 22 and FIG. 23, the upper end of the second main shaft 505 has a second adjustment portion 5053 exposed through the upper end of the second hollow portion G of the second sleeve 501 for cooperating with external devices to adjust the rotation of the second main shaft 505.

[0135] It should be understood that the second adjustment portion 5053 is used for cooperating with external tools. That is, the rotation angle of the second main shaft 505 is adjusted by cooperating with the second adjustment portion 5053 by the tool. For example, when the second main shaft 505 is rotated in the reverse direction (the direction of rotating to the right as shown in FIG. 23), the second moving part 506 will move downward, and at this time, the fifth spring 509 will be further compressed, and then the elastic force generated by the fifth spring 509 will be increased. After that, when it is needed to drive the second driving part 520 to rotate in the first direction (to the left as shown in FIG. 23), the required torque will be larger. Similarly, when the second main shaft 505 is rotated in the forward direction (the direction of rotating to the left as shown in FIG. 23), the second moving part 506 will move upward, and at this time, the compression amount of the fifth spring 509 will be reduced, and then the elastic force generated by the fifth spring 509 will be reduced. After that, when it is needed to drive the second driving part 520 to rotate in the first direction (to the left as shown in FIG. 23), the required torque will be smaller. Through the present solution, the torque of the spring torque device is adjusted. That is, according to the use requirements of different people, the second main shaft 505 can be adjusted in the forward direction or the reverse direction. When the spring torque device is used in a game controller, for adults, the second main shaft 505 can be adjusted in the reverse direction to increase the torque to meet the force habit of adults. Similarly, if the user is a child, then the second main shaft 505 can be adjusted in the forward direction to reduce the torque to meet the force habit of the child. That is, the force habit of ergonomics is met. In general, people who need greater torque can adjust the second main shaft 505 in the reverse direction, and people who need smaller torque can adjust the second main shaft 505 in the forward direction.

[0136] Specifically, as shown in FIG. 22 and FIG. 23, the second adjustment portion 5053 is a groove hole formed on the top end face of the second main shaft 505 and recessed inward. The groove hole is, for example, a cross-shaped groove hole for cooperating with a cross-shaped screwdriver; the groove hole can also be a hexagonal groove hole for cooperating with a hexagonal key. Of course, the groove hole can be any suitable shape to adapt to different tools. At this time, it is important that the second adjustment portion 5053 is exposed, so that the tool can be inserted to cooperate and adjust.

[0137] The second adjusting part 5053 is recessed in the second hollow part G of the second sleeve 501, or can extend to the outside of the second sleeve 501 in the axial direction, such as a protruding structure extending to the outside of the second sleeve 501, which can facilitate the tool clamping the protruding structure to realize the forward and reverse adjustment.

[0138] The second follower 510 and the second driver 520 have an axial constraint rotation plane perpendicular to the axial direction at the bottom end of the screw pair, which is used to constrain the axial movement of the second follower 510 and the second driver 520 and provide a space for the lateral non-transmission rotation of the second follower 510 and the second driver 520 after the screw pair is disengaged. Here, the bottom end refers to the bottom of the second follower 510 away from the second driver 520, and the bottom of the second driver 520 away from the second follower 510. That is, when the second follower 510 and the second driver 520 are closest to each other, if they are further rotated, the screw pair will be disengaged, and then if the second driver 520 continues to rotate in the second direction (the right direction shown in FIG. 23), the second driver 520 no longer generates an axial force on the second follower 510, and even if the second driver 520 is further rotated, it will not drive the second follower 510 to move axially. Such a scheme facilitates the control of the distance of the second follower 510 and the adaptation of the requirements of the force in the grading and zoning. Therefore, the space for the lateral non-transmission rotation of the second follower 510 and the second driver 520 after the screw pair is disengaged refers to that when the second driver 520 is closest to the second follower 510, if the second driver 520 is further rotated in the second direction, the second driver 520 no longer generates an axial force on the second follower 510 through the screw pair, and the further rotation will not drive the second follower 510 to move axially, but the second driver 520 can be further rotated in the second direction, and the second driver 520 will not rotate the second follower 510 in the process of rotation, because the second follower 510 can only move axially. In this application, the process of the second driver 520 being further rotated in the second direction into the axial constraint rotation plane without generating the axial movement of the second follower 510 is defined as the idle zone.

[0139] Specifically, the opposite ends of the second follower 510 and the second driver 520 are provided with force applying portions formed axially outward, each of the force applying portions is provided with a helical surface formed axially obliquely, and the helical surfaces of the force applying portion of the second follower 510 and the force applying portion of the second driver 520 are in surface contact when matched, thereby forming the helical motion pair; the axial constraint rotation planes of the second follower 510 and the second driver 520 are located outside the bottom of the helical surface of the respective force applying portions. Referring to FIGS. 26 and 27, the outside here refers to the right side of the helical surface of the second follower 510. For the second driver 520, the outside is the left side of the helical surface of the second driver 520.

[0140] As shown in FIGS. 26 and 27, the second follower 510 is provided with a first force applying portion 5106 formed spirally from the right upper side to the left lower side to form a first helical surface 5103, and a first axial constraint rotation plane 5104 is formed on the top right side of the first force applying portion 5106, which is perpendicular to the axial direction. The lower end surface of the first force applying portion 5106 is parallel to the first axial constraint rotation plane 5104. Correspondingly, the second driver 520 is provided with a second force applying portion 5201 formed spirally from the left lower side to the right upper side to form a second helical surface 5202, and a second axial constraint rotation plane 5203 is formed on the bottom left side of the second force applying portion 5201, which is perpendicular to the axial direction. The upper end surface of the second force applying portion 5201 is a plane and is parallel to the second axial constraint rotation plane 5203. That is, in this embodiment, the second driver 520 and the second follower 510 are both provided with two corresponding force applying portions, i.e., the first force applying portion 5106 and the second force applying portion 5201, and the corresponding helical surfaces and axial constraint rotation planes form a central symmetric structure design. Of course, it is not limited to this, and the second driver 520 and / or the second follower 510 can also be provided with three or more force applying portions. Simply increasing or reducing the force applying portions and the corresponding helical surfaces shall fall within the protection scope of the present application. In addition, the second follower 510 and the second driver 520 of the present embodiment in the present solution are of the same size and shape design on the respective force applying portions and the respective axial constraint rotation planes, which is more conducive to the close fit of the second follower 510 and the second driver 520 when matched. That is, the force applying portions, the helical surfaces, and the axial constraint rotation planes are the same structure design, but the directions are opposite when assembled, as shown in FIG. 27.

[0141] The first helical surface 5103 is in surface contact with the second helical surface 5202. When the second driven member 510 and the second driving member 520 are axially close to each other to the closest, the second force applying part 5201 enters into the first axial constraint rotation plane 5104 to contact, at this time, the right side of the second force applying part 5201, i.e. the second direction, the second driven member 510 leaves a preset space to meet the further rotation of the second driving member 520 into the first idle area 5105. That is, in the embodiment, the circumferential size of the upper end surface of the second force applying part 5201 is less than the circumferential size of the first axial constraint rotation plane 5104, so as to meet the idle rotation requirement. That is, when the upper end surface of the second force applying part 5201 just contacts the first axial constraint rotation plane 5104, the second driven member 510 has sufficient space on the right side (second direction) of the second force applying part 5201. Similarly, when the lower end surface of the first force applying part 5106 contacts the second axial constraint rotation plane 5203 on the left side (first direction) shown in FIG. 27, the second driving member 520 leaves sufficient space on the left side (first direction) of the first force applying part 5106 to further rotate in the second direction, i.e. to form the second idle area 5204.

[0142] When the lower end surface of the first force applying part 5106 contacts the second axial constraint rotation plane 5203, the upper end surface of the second force applying part 5201 also just contacts the first axial constraint rotation plane 5104. In this way, the rotation process of the second driven member 510 and the second driving member 520 is more stable.

[0143] As shown in FIG. 27, the second driven member 510 and the second driving member 520 both have two force applying parts uniformly distributed along the circumference, and the two force applying parts of the second driven member 510 and the second driving member 520 respectively cooperate to form two pairs of helical motion pairs. That is, the second driven member 510 has two first force applying parts 5106 along the circumference, and the second driving member 520 has two second force applying parts 5201 along the circumference. And the corresponding helical surfaces are uniformly distributed along the circumference and arranged in the same direction. The use of two groups of corresponding force applying parts to realize helical transmission cooperation is more conducive to the stability of the movement of the second driven member 510 and the second driving member 520.

[0144] At least a part of the second driving member 520 is exposed outside the second sleeve 501. This scheme facilitates the cooperation between the second driving member 520 and the structure of a specific application scenario. Specifically, in one specific embodiment, as shown in FIG. 22 and FIG. 23, the second driving member 520 has a first connecting portion 5206 extending below the second sleeve 501. Since it is exposed in use, it is very convenient to assemble. Specifically, as shown in FIG. 28, the first connecting portion 5206 has a third assembly hole 5207 arranged in the axial direction, and a second assembly hole 5205 arranged in the radial direction is arranged at the first connecting portion 5206, and the second assembly hole 5205 communicates with the third assembly hole 5207. When assembling, the structure of the application scenario (such as a connecting shaft) is inserted into the third assembly hole 5207, and then the connecting shaft can be locked by screwing through the second assembly hole 5205.

[0145] When an action force is applied to the rear part of the pedal 201, as shown in the upper right part of FIG. 8, FIG. 9 and FIG. 11, the pedal 201 drives the upper support frame 202 to rotate around the left-right shaft 102, at this time, the two compression spring devices 4 at both ends of the left-right shaft 102, one of which provides elastic force by compressing the spring, as shown by the two dashed circle positions of A in FIG. 8 and B in FIG. 9, converts the pressing force of the pedal 201 into the pressure of the compression spring device 4 by the compression spring force rod 403, and the other compression spring device 4 does not provide elastic force or tension due to the internal limit. The second potentiometer 602 is used to measure the angle data of the pedal 201 relative to the left-right shaft 102, that is, the change of the electric potential, and the angle data is converted into the required computer signal. Similarly, when an action force is applied to the front part of the pedal 201, the opposite is also true, as shown in the upper left part of FIG. 11.

[0146] Since the pedal 201 can only rotate forward or backward around the left-right shaft 102 relative to the six-end shaft 10, when the pedal 201 is pressed to the left, as shown in the lower left part of FIG. 11, the pedal 201 drives the front-rear shaft 101 to rotate, at this time, the two torsion spring devices 5 at both ends of the front-rear shaft 101, one of which provides torsion, and the other does not provide torsion. When an action force is applied to the pedal 201 to the right, the opposite is also true, as shown in the lower right part of FIG. 11. The first potentiometer 601 is used to measure the angle (electric potential) of the lower support frame 302 relative to the front-rear shaft 101, and the angle (electric potential) is converted into a computer signal to control the controlled object in the game.

[0147] In addition to the front, rear, left and right direction operation control in Figure 11, other direction operation control can also be performed, for example, right front or any one angle direction from the front, as shown in Figure 18, in which case two potentiometers simultaneously measure the angle (potential) of each rotation, and then together process and convert into corresponding computer signals to control the controlled objects in the game.

[0148] Of course, the player can also customize the function of stepping on the pedal, for example, applying a forward force to the pedal 201 to realize running, jumping and other actions, and a plurality of toe buttons (not shown in the figure) can also be provided on the pedal 201 to realize jumping, attacking, skill release and other functions. The buttons are designed as convex circles or ellipses, which are convenient for the toes to press accurately. These toe buttons are electrically connected with the main control board.

[0149] The main control board can be connected with the host computer or host through a data line to transmit signals, ensuring stable and low-delay connection. The main control board can also support Bluetooth 5.0 or higher version to connect with the computer or host signal, and the Bluetooth can be equipped with a 2.4GHz wireless receiver for connecting devices that do not directly support Bluetooth. Of course, if the Bluetooth wireless mode is used, the foot game controller also includes a rechargeable lithium battery (not shown in the figure), which can meet the long-time game demand after one charge. The main control board selects a high-performance and low-power microcontroller, such as the STM32 series, to process various sensor data (including but not limited to the data measured by the first potentiometer 601 and the second potentiometer 602) and communicate with external devices.

[0150] In order to meet the game needs of different players on different devices, the foot game controller not only supports common PC and host game platforms, but also can be seamlessly connected with mobile devices such as mobile phones and tablets, so that players can use foot control to play games in various scenes. For example, the player can connect the foot controller to the mobile phone through Bluetooth when going out, and play some hand games that support foot control operation, to improve the convenience and interest of game operation.

[0151] The pedal 201 can be made of metal sheet metal to ensure hardness and durability, or can be made of soft but certain supporting material to ensure comfort and durability. The second connecting rod 402 can be a fish eye joint bearing (fish eye joint).

[0152] The upper shaft 1031 and the lower shaft 1032 together form an up-down shaft 103, and the front shaft 101, the left shaft 102 and the up-down shaft 103 are perpendicular to each other and cross together to form a six-end shaft 10, as shown in Figures 5 and 6.

[0153] The six-end shaft 10 includes a six-end shaft body 11 and a bearing assembly 12 installed on the six-end shaft, as shown in FIG. 6, which includes a first clamping spring 121, a first gasket 122, a first sealing ring 123, a first sliding bearing sleeve 124, a second sealing ring 125, a second gasket 126, and a first spring 127. The front and rear shafts 101 and the left and right shafts 102 are both installed with the bearing assembly.

[0154] The upper support frame 202 is vertically arranged on the lower surface of the pedal 201, and the left and right shafts 102 pass through the upper support frame 202.

[0155] The first and second potentiometers 601 and 602 can be installed by means of hangers, and the first hanger 603 is installed on the lower support frame 302 or the lower plate 301. Specifically, as shown in FIG. 4, the first hanger 603 for fixing the first potentiometer 601 is installed on the lower support frame 302; as shown in FIG. 3, the second hanger 604 for fixing the second potentiometer 602 is installed on the upper support frame 202. The two hangers are fixedly connected to the lower support frame 302 and the upper support frame 202 by means of bolts, and the two potentiometers are fixedly connected to the two hangers by means of buckles or strong glue.

[0156] Specifically, as shown in FIG. 7, the upper part of the six-end shaft 10 is provided with an upper shaft 1031, and the upper shaft 1031 and the front and rear shafts 101 (or the left and right shafts 102) form a T-shaped shaft, and the front and rear sides of the upper shaft 1031 are provided with first damping devices 701. The lower part of the six-end shaft 10 is provided with a lower shaft 1032, and the lower shaft 1032 and the front and rear shafts 101 (or the left and right shafts 102) form a T-shaped shaft, and the left and right sides of the lower shaft 1032 are provided with second damping devices 702.

[0157] Specifically, the first damping device 701 includes a first impact head 7011 and a first damping body 7012 arranged at the end of the first impact head 7011. Similarly, the second damping device 702 also includes a second impact head 7021 and a second damping body 7022 arranged at the end of the second impact head 7021. The first damping body 7012 and the second damping body 7022 are both provided with threads, which can be screwed with the upper support frame 202 and the lower support frame 302. The damping body and the impact head are fixedly connected, so that the distance between the impact head of the damping device and the upper shaft 1031 or the lower shaft 1032 can be adjusted by rotating the damping body. For example, when the second potentiometer 602 or the first potentiometer 601 rotates by 3 degrees or less, the upper shaft 1031 or the lower shaft 1032 will not touch the first damping device 701 or the second damping device 702, and the torque applied to the pedal 201 will have a linear relationship with the rotation angle of the potentiometer. When the second potentiometer 602 or the first potentiometer 601 rotates by 3 degrees to 6 degrees, the upper shaft 1031 or the lower shaft 1032 will abut against the first damping device 701 or the second damping device 702, i.e., the upper shaft 1031 or the lower shaft 1032 will touch the first impact head 7011 or the second impact head 7021, and the torque applied to the pedal 201 will be greater, and the torque applied to the pedal 201 will have another relationship coefficient with the rotation angle of the potentiometer (since the damper usually contains a spring and a buffer oil, the buffer oil makes the damping displacement and the force applied to be nonlinear), and the relationship coefficient is greater than that when the first damping device 701 or the second damping device 702 is not abutted. In this way, the user can clearly distinguish the operation feeling when controlling the controlled object to move in the game, for example, the moving speed of the controlled object in the second case is much faster than that in the first case.

[0158] The relationship coefficient of the torque is changed by the two damping devices, for example, when the pedal 201 rotates forward by more than 3 degrees relative to the lower plate 301, i.e., the angle of rotation of the second potentiometer 602 is more than 3 degrees, due to the action of the damping device, the relationship coefficient of the torque received by the user is changed. The purpose of this is to reflect the difference in moving speed or the difference between different control keys. For example, when the pedal 201 is operated to rotate forward by more than 3 degrees, as shown in the upper left of FIG. 11, the moving speed of the controlled object is much greater than that when the potentiometer rotates by 3 degrees or less, which reflects the speed difference and improves the interest of game operation. The two damping devices can be spring dampers, which are composed of a spring and a damping element. The spring provides elastic force, and the damping element provides damping force.

[0159] Of course, the first damping device 701 and the second damping device 702 can also be removed, and the pedal 201 is provided with supporting torque by the torsion spring device 5 and the compression spring device 4. In this case, the torque applied to the pedal has a certain linear relationship with the rotation angle of the potentiometer, which is similar to the rocker on the game handle to control the movement of the controlled object.

[0160] If the player plays a yacht game and controls the steering wheel or keyboard, the player only needs to control the forward throttle and the backward throttle with the feet. The device can be changed into a foot pedal device that can only be stepped forward and backward by manual setting, and at this time, the pedal 201 of the device cannot rotate left or right relative to the lower plate 301. Similarly, if the player plays other games and only needs to control left and right with the feet, the device can also be changed into a foot pedal device that can only be stepped left and right by manual setting. That is, the device with two degrees of freedom (two degrees of freedom of rotation around the front and rear shaft 101 and the left and right shaft 102) is fixed with one degree of freedom and retains the other degree of freedom.

[0161] The specific operation is that the pedal 201 is provided with a front and rear limiting hole 2011 for limiting the rotation of the pedal 201 relative to the left and right shaft 102, and the upper end of the upper shaft 1031 is provided with a first threaded hole 10311 matched with the front and rear limiting hole 2011, as shown in FIG. 12; the lower plate 301 is provided with a left and right limiting hole 3011 for limiting the rotation of the lower plate 301 relative to the front and rear shaft 101, as shown in FIG. 13, and the lower end of the lower shaft 1032 is provided with a second threaded hole 10321 matched with the left and right limiting hole 3011; the periphery of the front and rear limiting hole 2011 and the left and right limiting hole 3011 is provided with an upper dustproof groove 2012 and a lower dustproof groove 3012. The dustproof groove can be a hexagonal groove or other shaped groove.

[0162] If it is not necessary to fix a certain degree of freedom, the front and rear limiting hole 2011 on the pedal 201 and the left and right limiting hole 3011 on the lower plate 301 are easy to let dust enter the interior of the device, especially large particles of dust are easy to fall into the interior of the device from the front and rear limiting hole 2011 under the action of gravity. Therefore, the front and rear limiting hole 2011 and the left and right limiting hole 3011 need to be covered with a dust cover.

[0163] As shown in FIG. 14, the upper dust cover 803 and the lower dust cover 804 can be made of iron sheet or plastic sheet. The outer side of the front and rear limiting hole 2011 and / or the left and right limiting hole 3011 has two small bolt holes, and the two dust covers are fixed by screws through the two bolt holes.

[0164] Embodiment 2

[0165] In addition, the device can also provide an inclined manner to give users more comfortable posture, as shown in Figure 15, in particular, the lower plate 301 under the front can be mounted a removable support frame 31, the removable support frame 31 to adjust the overall use of the controller angle, of course, can also not use the support frame, using other support mechanism. Therefore, the support frame needs to be set to be removable.

[0166] The removable support frame 31 can be fixed by positioning the bead (wave) way, as shown in Figure 16, specifically, the two support legs on the removable support frame 31 are provided with a groove, the lower plate 301 and the front fixed seat 305 are provided with two mounting holes adapted to the support leg, and the inside of the front fixed seat 305 is provided with a pair of positioning beads (wave). When the support frame is needed, the two support legs are inserted into the mounting hole, and the positioning bead (wave) is clamped into the groove on the support leg. When the support frame is needed to be removed, the removable support frame 31 is pulled out slightly.

[0167] The outside of the lower support frame 302 is provided with a front fixed seat 305 for fixing the torsion spring device 5. The front fixed seat 305 includes a front fixed seat base 3051, and a semicircular groove is provided in the middle of the front fixed seat base 3051. The torsion spring device 5 is installed in the semicircular groove, and then locked and fixed by the semicircular plate 3052.

[0168] As shown in Figure 3, Figure 17, the lower surface of the pedal 201 is provided with a pair of lifting frames 203 for fixing the compression spring device 4, and the lifting frames 203 fix the compression spring device 4 by bolts 204. Specifically, the lifting plate is provided in a U shape, and the compression spring device 4 is clamped in the U-shaped lifting frame 203. The compression spring device 4 has two first assembly holes 404 symmetrically arranged along the center axis, and then the two first assembly holes 404 are fixed by two bolts 204. The first assembly hole 404 is a smooth inner hole, and the first assembly hole 404 can be matched with the convex shaft 2041 on the bolt 204 to form a rotating sliding friction; the bolt 204 has a screw that can be threadedly connected with the lifting frame 203. In this way, the compression spring device 4 can be clamped under the pedal 201, and the compression spring device 4 has only one degree of freedom relative to the pedal 201, that is, the degree of freedom of rotation around the center axis of the convex shaft 2041.

[0169] The rear end of the pedal 201 is provided with an arc-shaped limiting plate 207. When the controller is placed obliquely, that is, the controller has a certain angle with the horizontal plane, as shown in FIG. 15, the arc-shaped limiting plate 207 is beneficial to place the foot on the pedal without sliding. Therefore, the shape of the arc-shaped limiting plate 207 is set to be the shape of the heel, that is, a circular arc shape, so that the foot is more comfortable, especially when used for a long time. The arc-shaped limiting plate 207 is provided with a pair of L-shaped connecting plates, and the L-shaped connecting plates are provided with a pair of waist-shaped holes 2071 for bolt installation, as shown in FIG. 3. The arc-shaped limiting plate 207 is fixed to the rear end of the pedal 201 through the waist-shaped holes 2071 and bolts. The position of the arc-shaped limiting plate 207 relative to the pedal 201 can be adjusted by adjusting the position of the waist-shaped holes 2071 and bolt assembly.

[0170] The present application can be used in various games, such as racing games, shooting games and role-playing games: combined with the foot controller to simulate moving, running, jumping and other actions, so that the game experience of the player is more immersive, especially suitable for players who have difficulty in controlling with both hands or have disabilities in both hands.

[0171] Compared with a manual game controller, the foot game controller can free the player's hands, so that he can focus on other operations, such as in a strategy game, the hands can be used to operate the mouse for precise clicking and some complex key operations, while the feet can be used to complete unit movement, view switching and other operations through the foot controller, greatly expanding the operation space and improving the game operation efficiency. In music rhythm games, the hands operate musical instruments, and the feet control rhythm changes, so that the player has a more rich game experience.

[0172] In addition, long-term use of a manual game controller can easily cause hand fatigue, while the foot game controller can distribute the operation burden to the feet. The muscle groups of the feet are relatively large and have stronger endurance, and are more suitable for long-term repetitive operation. For example, in a rowing game, the player uses the hands to control the steering wheel and shift for a long time, which can cause hand pain, while using the foot controller to control the throttle and reverse the boat can relax the hands, conform to the ergonomic principle, reduce the feeling of body fatigue, and enable the player to be more persistent in the game.

[0173] For some people who have difficulty in controlling with both hands or have disabilities in both hands, they can also use the device for daily office work. The user can customize the corresponding keyboard keys of the foot operation, solving the problem of affecting daily life and office work due to the problem of both hands. In addition, people who have difficulty in controlling with both hands or have disabilities in both hands may be at a disadvantage in intense competitive games due to the problem of both hands. The use of the device can to some extent make up for the operation problem caused by the problem of both hands, and bring a happier and more pleasant experience to people who have difficulty in controlling with both hands or have disabilities in both hands.

[0174] The pedal 201 and / or the upper support frame 202 in the specification is matched with the six-end shaft 10 through the left-right shaft 102. Of course, the pedal 201 and / or the upper support frame 202 can also be designed to be matched through the front-rear shaft 101, that is, the pedal 201 and / or the upper support frame 202 can only rotate left or right around the front-rear shaft 101 relative to the six-end shaft 10, and the lower plate 301 and / or the lower support frame 302 can only rotate forward or backward around the left-right shaft 102; that is, the two structure matching relationships of the six-end shaft 10 and the upper support frame 202 and the lower support frame 302 are reversed, and the torsion spring device 5 is fixed to the pedal 201, and the compression spring device 4 is fixed to the lower plate 301, and the specific implementation process is the same as the principle described above. The design method of the exchanged matching relationship should fall within the protection scope of the present application.

[0175] In addition, the pedal 201 can be designed to be suitable for two feet to step on, in which case the compression spring device 4 can be replaced by the torsion spring device 5.

[0176] In summary, the present application discloses a foot game controller, that is, the controlled object in the game can be moved by controlling the pedal, at the same time, the player can also customize the function of stepping on the pedal, for example, applying a forward force to realize running, jumping and other actions, which is suitable for players who need to operate more keys, especially for players who are inconvenient to use both hands. In addition, the use of damping makes the player have a clear speed difference when moving the controlled object in the game, and the player has a more rich game experience.

[0177] Obviously, the above-described embodiments are only part of the embodiments of the present application, not all the embodiments, and the preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be implemented in many different forms, and on the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive. Any equivalent structure made by using the content of the specification and the drawings, directly or indirectly applied to other related technical fields, is also within the patent protection scope of the present application.
