[0002] In the prior art, a game steering wheel assembly includes a steering wheel, a rotating shaft and a torsion spring. A circumferential limiting structure cooperating with the torsion spring is provided on the rotating shaft. When the steering wheel is rotated, the rotating shaft twists the torsion spring and stores elastic potential energy through the circumferential limiting structure. When the steering wheel is released, the torsion spring applies a reset torque to the rotating shaft through the circumferential limiting structure so that the steering wheel can be automatically reset.

[0041] like Figure 1As shown, in the first aspect, an embodiment of the present application provides a game steering wheel assembly (hereinafter referred to as steering wheel assembly 100), which relates to the field of vehicle simulator technology, and is mainly used in car simulators, racing simulators, etc., for simulating a real steering wheel control experience.

[0042] Combination Figures 1 to 3 As shown, the steering wheel assembly 100 mainly includes: a base 180 , a control component 110 , a first elastic component 121 and a second elastic component 122 .

[0043] Among them, the control assembly 110 includes: a steering wheel 111 rotatably arranged at one end of the base 180, a screw shaft 112 rotatably passed through the base 180 and connected to the steering wheel 111, and a sliding member 113 slidably connected to the base 180 along the axial direction of the screw shaft 112. The sliding member 113 is sleeved on the part of the screw shaft 112 away from the steering wheel 111 through a ball nut 114.

[0044] The first elastic component 121 is disposed at one end of the base 180 close to the steering wheel 111 , the second elastic component 122 is disposed at one end of the base 180 away from the steering wheel 111 , and the sliding member 113 is located between the first elastic component 121 and the second elastic component 122 .

[0045] The first elastic component 121 and the second elastic component 122 each include a stop arm 1211 and an elastic element 1212. The elastic element 1212 is, for example, a cylindrical spring, a spring sheet, or a combination of a cylindrical spring and a shock absorber. The stop arm 1211 is slidingly connected to the base 180 along the axial direction of the screw shaft 112. The elastic element 1212 is rotationally connected to the base 180 and the stop arm 1211, respectively, and the elastic element 1212 is inclined relative to the axis of the screw shaft 112.

[0046] like Figure 1 As shown, exemplarily, when the player rotates the steering wheel 111 in the counterclockwise direction a, the steering wheel 111 drives the screw shaft 112 to rotate around its axis, so as to drive the sliding member 113 to slide in a direction away from the steering wheel 111 through the ball nut 114. During the sliding of the sliding member 113, the blocking arm 1211 of the second elastic component 122 is pushed to slide, and the blocking arm 1211 of the first elastic component 121 is not in contact, so that the elastic element 1212 of the second elastic component 122 is gradually compressed. When the player releases the steering wheel 111, the elastic potential energy stored in the elastic element 1212 is converted into kinetic energy, which can apply elastic force to the sliding member 113 through the blocking arm 1211, thereby driving the screw shaft 112 to rotate through the ball nut 114, so that the steering wheel 111 rotates clockwise in the direction b and resets.

[0047] When the player rotates the steering wheel 111 in the clockwise direction b, the sliding member 113 slides in the direction close to the steering wheel 111 and pushes the blocking arm 1211 of the first elastic component 121 to slide without contacting the blocking arm 1211 of the second elastic component 122, so that the elastic element 1212 of the first elastic component 121 is gradually compressed. When the steering wheel 111 is released, the elastic element 1212 of the first elastic component 121 applies an elastic force to the sliding member 113 through the blocking arm 1211, thereby driving the screw shaft 112 to rotate through the ball nut 114, so that the steering wheel 111 rotates counterclockwise in the direction a to reset.

[0048] Combination Figure 3 and Figure 4 As shown, it should be noted that, taking the rotation of the steering wheel 111 in the counterclockwise direction a as an example, since the elastic element 1212 is tilted relative to the axis of the screw shaft 112, during the resetting process of the steering wheel 111, the elastic force F applied by the elastic element 1212 to the sliding member 113 gradually decreases, but the inclination angle θ of the elastic element 1212 relative to the screw shaft 112 gradually decreases, and the elastic force F is decomposed, and its component force Fx=Fcosθ in the axial direction of the screw shaft 112, and its component force Fy=Fsinθ in the direction perpendicular to the axial direction of the screw shaft 112.

[0049] The direction of Fy is perpendicular to the axis of the screw shaft 112, so no force is applied to the steering wheel 111. As F decreases, the value of cosθ gradually increases, so that the magnitude of Fx tends to be constant, so that during the process of the steering wheel 111 rotating and resetting, the player can feel the constant resetting torque from the steering wheel 111, which is closer to the feeling that the driver feels when the steering wheel 111 of a real vehicle is reset.

[0050] In addition, when the player rotates the steering wheel 111 clockwise b or counterclockwise a, the elastic force F gradually increases, and the inclination angle θ of the elastic element 1212 relative to the screw shaft 112 gradually increases. As the elastic force F gradually increases, cosθ gradually decreases, so the size of Fx also tends to be constant. In this way, in the process of rotating the steering wheel 111, the player can feel a constant reverse torque from the steering wheel 111, which is closer to the feeling brought to the driver when the steering wheel 111 of a real vehicle is rotated.

[0051] In the prior art, the steering wheel assembly includes a steering wheel, a rotating shaft and a torsion spring. A circumferential limiting structure cooperating with the torsion spring is provided on the rotating shaft. When the steering wheel is rotated, the rotating shaft twists the torsion spring and stores elastic potential energy through the circumferential limiting structure. When the steering wheel is released, the torsion spring applies a reset torque to the rotating shaft through the circumferential limiting structure so that the steering wheel can be automatically reset.

[0052] However, with the above structure, as the player rotates the steering wheel, the reverse torque felt gradually increases, and when the steering wheel is released, the reset torque felt gradually decreases, which fails to simulate the real vehicle steering wheel control experience and reduces the player's user experience.

[0053] Compared with the above technical solution, the steering wheel assembly 100 provided in this embodiment, the screw shaft 112 and the ball nut 114 form a ball screw mechanism, which can realize the mutual conversion between the rotational motion of the steering wheel 111 and the linear motion of the sliding member 113.

[0054] On this basis, by setting the elastic element 1212 at an angle, the component force Fx of the elastic force F applied by the elastic element 1212 to the sliding member 113 in the axial direction of the screw shaft 112 tends to be constant. In this way, when the player rotates the steering wheel 111 or releases the steering wheel 111, the player can feel the constant reverse torque and reset torque from the steering wheel 111, which is closer to the feeling brought to the driver when operating the steering wheel 111 of a real vehicle, thereby improving the player's usage experience and the market competitiveness of the product.

[0055] like Figure 3 As shown, in one embodiment, when the steering wheel 111 is reset, that is, when the steering wheel 111 is in the centered state, the inclination angle θ of the elastic element 1212 relative to the screw shaft 112, that is, the initial inclination angle θ of the elastic element 1212, satisfies the relationship: 20°≤θ≤30°.

[0056] After testing, the results of players' experience of Examples 1-5 and Comparative Examples 1-2 are shown in Table 1.

[0057]

[0058] It can be seen that by setting the elastic element 1212 that satisfies the above relationship, the control resistance felt by the player when rotating the steering wheel 111 is moderate, that is, the reverse torque received by the player when rotating the steering wheel 111 is relatively moderate. At the same time, when the player completely releases the steering wheel 111, the reset torque applied by the elastic element 1212 to the steering wheel 111 is also relatively moderate, so that the reset speed of the steering wheel 111 is moderate and can meet the control needs of most players.

[0059] In this embodiment, when the steering wheel 111 is reset, the inclination angle θ of the elastic element 1212 relative to the screw shaft 112 can preferably be 25°. Of course, it can also be set to 20°, 21°, 22°, 23°, 24°, 24.5°, 25.5°, 26°, 27°, 28°, 29°, 30°, etc., and can be set specifically according to different game car models.

[0060] like Figure 2 , Figure 3 and Figure 5 As shown, further, the steering wheel assembly 100 also includes a first adjusting component 130, the first adjusting component 130 includes a first screw rod 131, a first slider 132 and a second slider 133, the first slider 132 and the second slider 133 are both sleeved on the first screw rod 131 through a nut 134, the first slider 132 is rotatably connected to the elastic element 1212 of the first elastic component 121, and is slidably connected to the base 180 along the axial direction of the screw shaft 112, the second slider 133 is rotatably connected to the elastic element 1212 of the second elastic component 122, and is slidably connected to the base 180 along the axial direction of the screw shaft 112, the first screw rod 131 is rotatably penetrated in the base 180 along the axial direction of the screw shaft 112, and is used to adjust the distance between the first slider 132 and the second slider 133.

[0061] When the first screw rod 131 rotates around its axis, the first screw rod 131 drives the first slider 132 and the second slider 133 to move closer to or away from each other through the corresponding nut 134 to adjust the distance between the first slider 132 and the second slider 133, thereby adjusting the size of the inclination angle θ of the elastic element 1212 relative to the screw rod shaft 112 when the steering wheel 111 is in the centering state, that is, the initial inclination angle θ of the elastic element 1212. For example, the initial inclination angle θ is adjusted to 20°, 22°, 25°, 27°, 30°, etc., to achieve stepless adjustment of the control resistance of the steering wheel 111 and the reset speed of the steering wheel 111.

[0062] In addition, the first screw rod 131 and the nut 134 form a trapezoidal screw mechanism, which can convert the rotational motion of the first screw rod 131 into the linear motion of the first slider 132 and the second slider 133, but cannot realize the conversion of linear motion into rotational motion, that is, the trapezoidal screw mechanism has self-locking properties, so when the initial tilt angle θ is adjusted, the first slider 132 and the second slider 133 can remain stable.

[0063] like Figure 5 As shown, further, the steering wheel assembly 100 also includes a first driver 174 and a first transmission assembly 175. The first driver 174 is, for example, a rotary motor or a drive motor. The first driver 174 is disposed on the base 180 and is connected to the first screw rod 131 through the first transmission assembly 175. The first driver 174 drives the first screw rod 131 to rotate through the first transmission assembly 175.

[0064] When the initial tilt angle θ of the elastic element 1212 needs to be adjusted, the first driver 174 drives the first screw rod 131 to rotate around its axis through the first transmission assembly 175, thereby driving the first slider 132 and the second slider 133 to move away from or approach each other, so that the initial tilt angle θ of the elastic element 1212 is reduced or increased, thereby realizing stepless adjustment.

[0065] Continue reading Figure 5 In a specific embodiment, the first transmission assembly 175 includes a driving gear 1751 and a driven gear 1752. The driven gear 1752 is sleeved on the end of the first screw rod 131 away from the steering wheel 111. The driving gear 1751 is connected to the output part of the first driver 174 and meshes with the driven gear 1752. The first driver 174 is used to drive the driving gear 1751 to rotate, so as to drive the driven gear 1752 to rotate, thereby driving the first screw rod 131 to rotate, so as to realize the stepless adjustment of the initial inclination angle θ of the elastic element 1212.

[0066] In another specific embodiment, the first transmission assembly 175 includes a worm and a turbine. The turbine is sleeved on the end of the first screw 131 away from the steering wheel 111. One end of the worm is connected to the output part of the first driver 174. The part of the worm away from the first driver 174 is engaged with the turbine teeth of the turbine, which can also achieve stepless adjustment of the initial inclination angle θ of the elastic element 1212.

[0067] Of course, a rotating handle may also be provided at the end of the first screw rod 131 away from the steering wheel 111 , so that the user can manually rotate the first screw rod 131 to manually adjust the initial tilt angle θ of the elastic element 1212 .

[0068] Combination Figure 1 , Figure 5 and Figure 6 As shown, in one embodiment, the game steering wheel assembly 100 also includes a first damping buffer 151 and a second damping buffer 152, both of which are fixed on the sliding member 113, and the screw shaft 112 is located between the first damping buffer 151 and the second damping buffer 152. A first support plate 171 and a second support plate 172 are provided on the base 180, and the first support plate 171 is arranged close to the steering wheel 111 for supporting the piston rod 153 of the first damping buffer 151, and the second support plate 172 is arranged away from the steering wheel 111 for supporting the piston rod 153 of the second damping buffer 152.

[0069] When the player rotates the steering wheel 111 in the counterclockwise direction a, the sliding member 113 pushes the stop arm 1211 of the second elastic component 122, while driving the second damping buffer 152 to move in the direction of the second support plate 172, so that the piston rod 153 of the second damping buffer 152 is gradually compressed, so that the player feels the damping when rotating the steering wheel 111. When the player releases the steering wheel 111, the sliding member 113 slides and resets under the action of the second elastic component 122. During the sliding and resetting process, the piston rod 153 of the second damping buffer 152 gradually extends, and the piston rod 153 of the first damping buffer 151 does not contact the first support plate 171, so that no damping is generated during the rotation and resetting process of the steering wheel 111.

[0070] When the player rotates the steering wheel 111 in the clockwise direction b, the sliding member 113 pushes the stop arm 1211 of the first elastic component 121 to slide, and at the same time drives the first damping buffer 151 to move toward the first support plate 171, so that the piston rod 153 of the first damping buffer 151 is gradually compressed, so that the player can feel the damping. Similarly, when the player releases the steering wheel 111, the sliding member 113 slides and resets under the action of the first elastic component 121. During the reset process, the piston rod 153 of the first damping buffer 151 gradually extends, and the piston rod 153 of the second damping buffer 152 does not contact the second support plate 172, so that no damping is generated during the rotation and reset of the steering wheel 111.

[0071] It can be seen that through the above design, when the player rotates the steering wheel 111, he will feel the damping feeling, and when the steering wheel 111 is released until the steering wheel 111 returns to the center, the damping feeling disappears. This is closer to the real driving experience, increases the realism during the game, and enhances the player's experience.

[0072] like Figure 6 As shown, further, the steering wheel assembly 100 also includes a second driver and a second transmission assembly, the second driver is arranged on the base 180, and is connected to the adjustment knob 154 of the first damping buffer 151 (the structure of the adjustment knob 154 is not shown in the drawings) through the second transmission assembly.

[0073] Exemplarily, the second driver may be a rotary electric machine or a drive motor, and the second transmission assembly may be a gear assembly or a worm gear assembly.

[0074] In this embodiment, the second driver is used to drive the adjustment knob 154 of the first damping buffer 151 to rotate through the second transmission component, so as to cooperate with the software design to automatically adjust the damping size of the first damping buffer 151 before the player uses it, or automatically adjust the damping size of the first damping buffer 151 according to the game scene during the player's use, thereby bringing a more realistic control experience to the player.

[0075] Of course, the above design may also be adopted on the second damping buffer 152 , that is, the second driver is connected to the adjustment knob 154 of the second damping buffer 152 through the second transmission assembly.

[0076] like Figure 1 As shown, further, the part of the screw shaft 112 away from the steering wheel 111 is rotatably penetrated through the first support plate 171 and the second support plate 172, for example, by opening a shaft through hole on the first support plate 171 and the second support plate 172, or by connecting through bearings.

[0077] In this embodiment, the first support plate 171 and the second support plate 172 are used to support the screw shaft 112 to ensure smooth rotation of the screw shaft 112, and are also used to support the piston rod 153 of the first damping buffer 151 and the second damping buffer 152, thereby reducing the use of support structures and improving the structural compactness of the steering wheel assembly 100.

[0078] like Figure 3 and Figure 6 As shown, in one embodiment, the base 180 includes a bottom plate 181, a first end plate 182 and a second end plate 183, the bottom plate 181 is connected between the first end plate 182 and the second end plate 183, the screw shaft 112 is rotatably passed through the first end plate 182, for example, connected by a ball bearing, a guide shaft 184 is passed between the first end plate 182 and the second end plate 183, and the sliding member 113 and the stop arm 1211 are respectively sleeved on the guide shaft 184 through linear bearings 173.

[0079] In this embodiment, the sliding member 113 and the stop arm 1211 are respectively mounted on the guide shaft 184 through the linear bearings 173. The guide shaft 184 cooperates with the linear bearings 173 to provide a guiding function for the sliding member 113 and the stop arm 1211, so that the sliding member 113 and the stop arm 1211 can slide smoothly, making it easier for the player to operate the steering wheel 111, thereby improving the user experience.

[0080] Of course, the first slider 132 and the second slider 133 may also be sleeved on the guide shaft 184 via the linear bearing 173 , so that the first slider 132 and the second slider 133 can slide smoothly, thereby facilitating the adjustment of the initial tilt angle θ of the elastic element 1212 .

[0081] In addition, the first slider 132, the second slider 133, the stop arm 1211 of the first elastic component 121, the stop arm 1211 of the second elastic component 122 and the sliding member 113 are all mounted on the same guide shaft 184, which can improve the movement consistency of each component, thereby further improving the smoothness of the player's operation of the steering wheel 111.

[0082] In another embodiment, a slide rail may be used instead of the guide shaft 184, and a slider adapted to the slide rail may be used instead of the linear bearing 173. The first slider 132, the second slider 133, the stop arm 1211 of the first elastic component 121, the stop arm 1211 of the second elastic component 122, and the sliding member 113 may also be guided to make the operation of the steering wheel 111 smoother.

[0083] In a specific embodiment, a ranging sensor, such as an infrared sensor or a laser sensor, is disposed on the first end plate 182 or the second end plate 183, and the detection end of the ranging sensor is disposed toward the sliding member 113, for detecting the distance between the sliding member 113 and the first end plate 182, or the distance between the sliding member 113 and the second end plate 183, thereby facilitating indirect calculation of the real-time rotation angle of the steering wheel 111.

[0084] In another specific embodiment, a pressure sensor is provided on the side of the barrier arm 1211 facing the sliding member 113 or on the side of the sliding member 113 facing the barrier arm 1211, and the pressure sensor is used to obtain the contact pressure between the sliding member 113 and the barrier arm 1211, so as to indirectly calculate the real-time rotation angle of the steering wheel 111 through the contact pressure.

[0085] In yet another specific embodiment, a sliding rheostat is disposed on the bottom plate 181 , and a sliding piece of the sliding rheostat is connected to the sliding member 113 .

[0086] It should be pointed out that the sliding rheostat is a circuit element that can change its own resistance to control the circuit. The structure of the sliding rheostat generally includes five parts: terminal, slider, resistance wire, metal rod and porcelain tube. The resistance wire is wound on the insulating porcelain tube.

[0087] In this embodiment, a sliding rheostat is provided on the bottom plate 181, and the sliding piece of the sliding rheostat is connected to the sliding member 113. When the sliding member 113 slides, the sliding piece can be driven to slide along the metal rod, thereby facilitating the indirect acquisition of the rotation angle of the steering wheel 111 through the change in the resistance of the sliding rheostat itself.

[0088] Of course, for the above embodiment, a sensing element may also be provided on the sliding member 113, and a detection element may be provided on the side of the first end plate 182 facing the sliding member 113. The detection element cooperates with the sensing element to detect the relative position of the sliding member 113 and the first end plate 182, thereby facilitating indirect acquisition of the rotation angle of the steering wheel 111 through the relative position of the sliding member 113 and the first end plate 182.

[0089] Exemplarily, the sensing element can be a magnet and the detecting element is a Hall sensor. It can be understood that the Hall sensor has the advantages of stable performance, small size, low power consumption, high frequency, and anti-pollution. When used in conjunction with a magnet, it can accurately detect the relative position of the sliding member 113 and the first end plate 182.

[0090] Of course, the sensing element may also be an electronic tag, and the detecting element may be a wireless radio frequency detector, and the two may be used together to detect the relative position of the sliding member 113 and the first end plate 182 .

[0091] In addition, the detection element may also be disposed on the side of the second end plate 183 facing the sliding member 113 to cooperate with the sensing element to detect the relative position of the sliding member 113 and the second end plate 183 , and the rotation angle of the steering wheel 111 may also be indirectly acquired.

[0092] like Figure 2 , Figure 3 and Figure 5 As shown, in one embodiment, the steering wheel assembly 100 also includes a second adjusting component 140, which includes a second screw rod 141, a first nut 142 and a second nut 143. The first nut 142 and the second nut 143 are respectively slidably connected to the base 180 through a guide rod 144, and are respectively sleeved on the second screw rod 141, and are respectively located on two opposite sides of the sliding member 113 along the axial direction of the screw shaft 112. The second screw rod 141 is rotatably arranged on the base 180, and the sliding member 113 is located at the first nut 142 and the second nut 143. The first nut 142 and the second nut 143 can respectively abut against the sliding member 113 to limit the rotation angle of the steering wheel 111.

[0093] In this embodiment, the distance between the first nut 142 and the second nut 143 can be adjusted by the second screw rod 141, so as to achieve stepless adjustment of the rotation angle of the steering wheel 111.

[0094] Combination Figure 7 and Figure 8 As shown, in one embodiment, the steering wheel assembly 100 further includes a force feedback mechanism 190 disposed between the steering wheel 111 and the base 180, and the force feedback mechanism 190 includes a planetary gear assembly 191, a gear plate 192, a third driver 193, a driving gear 194, and a locker 195. The third driver 193 is, for example, a rotary motor or a driving motor, and the locker 195 has a lock shaft 1951, such as an electric push rod, an electric cylinder, a pneumatic cylinder, etc.

[0095] Among them, the planetary gear assembly 191 includes a gear ring 1911, a center gear 1912, a first gear 1913, a second gear 1914, a third gear 1915 and a bracket 1916. The screw shaft 112 is rotatably inserted into the gear disc 192 and the center gear 1912. The center gear 1912 is fixedly connected to the middle part of the gear disc 192. The first gear 1913, the second gear 1914 and the third gear 1915 are arranged along the circumference of the center gear 1912, and are respectively meshed with the inner ring teeth 19111 of the gear ring 1911, and are respectively rotatably connected to the bracket 1916.

[0096] The screw shaft 112 is inserted into the bracket 1916 and locked with the bracket 1916 in the circumferential direction of the screw shaft 112, that is, the screw shaft 112 cannot rotate relative to the bracket 1916. The driving gear 194 is engaged with the toothed disc 192 and connected to the output portion of the third driver 193. The third driver 193 is arranged on the base 180. A plurality of slots 19112 are provided along the outer ring wall of the gear ring 1911. The locker 195 is arranged on the base 180 and has a lock shaft 1951 for inserting into the slots 19112.

[0097] When the lock shaft 1951 is not inserted into the slot 19112 , the player can rotate the steering wheel 111 freely. When the steering wheel 111 is released, the steering wheel 111 can be rotated and reset under the drive of the first elastic component 121 or the second elastic component 122 , so that the steering wheel 111 is returned to the center.

[0098] When the lock shaft 1951 is inserted into the slot 19112, the third driver 193 drives the toothed disc 192 to rotate through the driving gear 1751, so as to drive the first gear 1913, the second gear 1914, and the third gear 1915 to revolve around the center gear 1912 through the center gear 1912, thereby driving the bracket 1916 to rotate, so that the bracket 1916 drives the screw shaft 112 and the steering wheel 111 to rotate, thereby giving players force feedback in specific game scenarios, such as simulating the experience of a vehicle passing through a bumpy road or a collision, thereby improving the realism of the game and enhancing the user experience.
