[0003] Currently, the steering wheel mechanism of vehicle simulators applies torque to the main shaft through the drive component. This torque is transmitted to the steering wheel controlled by the user through the main shaft to provide force feedback, which helps to simulate special driving scenarios (such as driving on bumpy roads, vehicle collisions, etc.). However, when force feedback is not required, the connection between the drive component and the main shaft makes it more difficult for the user to turn the steering wheel, thus affecting the handling feel of the steering wheel mechanism.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] Furthermore, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that they are in indirect contact through an intermediate medium. Moreover, "above" or "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below" or "below" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this application, the terms "first," "second," etc., are used to distinguish different objects and should not be construed as indicating or implying a specific order or primary / secondary relationship, or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0034] In the description of this application, the term "multiple" means two or more, unless otherwise explicitly specified. The term "multiple A and multiple B in one-to-one correspondence" can be understood as: the number of A and the number of B are the same, and there is a one-to-one mapping relationship, that is, each A corresponds to only one B, and each B also corresponds to only one A.

[0035] In the description of this application, unless otherwise explicitly specified, the terms "installation," "connection," "attachment," etc., should be interpreted broadly. For example, they can refer to a non-detachable connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Additionally, the character " / " generally indicates that the preceding and following objects have an "or" relationship.

[0037] In the description of this application, the term "fixed connection" can be understood as: two objects whose relative positions remain unchanged under normal use conditions, that is, they will not easily undergo relative movement (e.g., relative rotation and relative movement); for example, a fixed connection can be a threaded connection, a snap-fit ​​connection, welding, riveting, magnetic connection, friction contact connection, etc., without any specific limitations.

[0038] A vehicle simulator is a virtual gaming device that provides users with an immersive driving experience, allowing them to practice driving skills in a safe environment and enjoy the thrill and fun of racing. Currently, the steering wheel mechanism of a vehicle simulator applies torque to the main shaft through a drive component. This torque is transmitted through the main shaft to the steering wheel controlled by the user to provide force feedback, thereby helping to simulate special driving scenarios (such as driving on bumpy roads, vehicle collisions, etc.).

[0039] However, when no force feedback is required, i.e., in normal driving scenarios (such as when the vehicle is driving on a flat road and there is no collision), the connection between the drive components and the main shaft makes it more difficult for the user to turn the steering wheel, thus affecting the steering feel.

[0040] like Figure 1 As shown, in order to solve the above-mentioned technical problems, the embodiments of this application provide a steering wheel device 100, which relates to the field of vehicle simulator technology and is mainly used in vehicle simulators; of course, the steering wheel device 100 can also be used in ship simulators, and no specific limitation is made to the application scenario of the steering wheel device 100 here.

[0041] like Figures 1 to 3 As shown, the steering wheel device 100 provided in this embodiment includes: a body 110, a first drive member 121, a main shaft 122, a steering wheel 123, and an electromagnetic clutch 130.

[0042] The first driving component 121 is disposed on the body 110; the main shaft 122 is rotatably connected to the body 110; the steering wheel 123 is fixedly connected to the main shaft 122; the electromagnetic clutch 130 is disposed on the body 110, the output shaft 131 of the electromagnetic clutch 130 is connected to the main shaft 122, and the input shaft 132 of the electromagnetic clutch 130 is connected to the first driving component 121. The first driving component 121 is used to drive the input shaft 132 to rotate; when the electromagnetic clutch 130 is energized, the input shaft 132 and the output shaft 131 are fixedly connected; when the electromagnetic clutch 130 is de-energized, the input shaft 132 and the output shaft 131 are separated.

[0043] It should be noted that the electromagnetic clutch 130 is a device that controls the clutch state through electromagnetic force. Its working principle is as follows: When the electromagnetic clutch 130 is energized, the electromagnetic coil generates a magnetic field, and the magnetic lines of force form a closed magnetic circuit in the magnetic yoke. The driven plate (which is fixedly connected to the output shaft 131 and is made of ferromagnetic material) is attracted by the magnetic force and presses against the drive plate (which is fixedly connected to the input shaft 132). At this time, the drive plate and the driven plate transmit torque through frictional contact. When the electromagnetic clutch 130 is de-energized, the electromagnetic coil is not energized, and the spring or reset mechanism pulls the driven plate away from the drive plate. At this time, there is no contact between the drive plate and the driven plate, so torque cannot be transmitted.

[0044] It is understood that the steering wheel device 100 provided in this embodiment, due to the presence of an electromagnetic clutch 130, has its output shaft 131 connected to the main shaft 122 and its input shaft 132 connected to the first drive member 121, which drives the input shaft 132 to rotate. Thus, when the electromagnetic clutch 130 is energized, the input shaft 132 and output shaft 131 are fixedly connected, allowing the torque output by the first drive member 121 to be transmitted to the steering wheel 123 via the main shaft 122, thereby simulating special driving scenarios. When the electromagnetic clutch 130 is de-energized, the input shaft 132 and output shaft 131 are separated, cutting off the connection between the main shaft 122 and the first drive member 121, improving the effort required for the user to turn the steering wheel 123 in normal driving scenarios, thereby enhancing the handling feel of the steering wheel device 100.

[0045] like Figure 1 , Figure 3 and Figure 6 As shown, in some embodiments, the steering wheel device 100 further includes a first transmission mechanism 140, which includes a first gear 141 and a second gear 142. The first gear 141 is fixedly connected to the first output shaft 1211 of the first drive member 121, and the second gear 142 is fixedly connected to the input shaft 132 and meshes with the first gear 141. The number of teeth of the second gear 142 is greater than the number of teeth of the first gear 141. In this way, the output torque of the first drive member 121 can be amplified and transmitted to the input shaft 132 of the electromagnetic clutch 130. Thus, when the electromagnetic clutch 130 is energized, the torque is transmitted sequentially to the steering wheel 123 via the output shaft 131 and the main shaft 122, allowing the user to feel a stronger force feedback, thereby helping to more realistically simulate special driving scenarios.

[0046] Furthermore, with the torque amplified, a lower-grade first drive component 121 can be used, which helps to miniaturize the steering wheel device 100 and reduce the manufacturing cost of the steering wheel device 100.

[0047] like Figure 5 As shown, furthermore, multiple first drive members 121 and multiple first gears 141 are provided. The multiple first drive members 121 are distributed at intervals along the circumference of the electromagnetic clutch 130, and the multiple first gears 141 are connected to the multiple first drive members 121 in a one-to-one correspondence. In this way, more selectivity is provided in terms of torque, so as to better provide force feedback to the user.

[0048] like Figure 1 , Figure 2 and Figure 7As shown, in some embodiments, the steering wheel device 100 further includes a second transmission mechanism 150, which includes a third gear 151 and a fourth gear 152. The third gear 151 is fixedly connected to the output shaft 131, and the fourth gear 152 is connected to the main shaft 122 and meshes with the third gear 151. The number of teeth of the fourth gear 152 is greater than the number of teeth of the third gear 151. This further amplifies the output torque of the first drive member 121, allowing the user to feel a stronger force feedback, thereby helping to more realistically simulate special driving scenarios.

[0049] like Figures 1 to 3 as well as Figure 8 As shown, the steering wheel device 100 further includes a third transmission mechanism 160, which includes a sun gear 161, an internal gear ring 162, a first planetary carrier 163, and a plurality of planetary gears 164. The internal gear ring 162 is fixedly connected to the body 110, and the plurality of planetary gears 164 are distributed at intervals along the circumference of the sun gear 161. Each planetary gear 164 is rotatably connected to the first planetary carrier 163, and each planetary gear 164 meshes with the sun gear 161 and the internal gear ring 162 respectively. The sun gear 161 is fixedly connected to the fourth gear 152, and the first planetary carrier 163 is fixedly connected to the main shaft 122. In this way, the torque output by the fourth gear 152 can be transmitted sequentially to the steering wheel 123 via the sun gear 161, planetary gear 164, first planetary carrier 163 and main shaft 122. In the transmission process from the sun gear 161 to the first planetary carrier 163, the torque is amplified and the speed is reduced, which reduces the torque and increases the speed. This helps to simulate special driving scenarios more realistically and optimize the handling feel.

[0050] like Figure 6 and Figure 7 As shown, the internal gear ring 162 further includes multiple tooth segments 1622, which are connected in a ring to form the internal gear ring 162.

[0051] Understandably, the current one-piece molded internal gear ring generates a significant amount of waste during manufacturing, thus increasing the manufacturing cost of the steering wheel assembly 100. By manufacturing the internal gear ring 162 in multiple tooth segments 1622, waste generation can be reduced, thereby lowering the manufacturing cost of the steering wheel assembly 100.

[0052] like Figure 3 and Figure 4 As shown, the sun gear 161 is rotatably connected to the first planetary carrier 163, which facilitates the installation of the sun gear 161 and helps to improve the stability of the sun gear 161. Furthermore, it does not affect the relative rotation between the sun gear 161 and the first planetary carrier 163.

[0053] like Figure 1 , Figure 3 and Figure 8 As shown, the steering wheel device 100 further includes a fourth transmission mechanism 170 and a second drive member 124. The fourth transmission mechanism 170 includes a fifth gear 171 and an external gear ring 172. The second drive member 124 is disposed on the body 110, and the second output shaft 1241 of the second drive member 124 is fixedly connected to the fifth gear 171. The second drive member 124 is used to drive the fifth gear 171 to rotate. The third transmission mechanism 160 also includes a second planetary carrier 165. Each planetary gear 164 is also rotatably connected to the second planetary carrier 165. The external gear ring 172 is fixedly connected to the second planetary carrier 165 and meshes with the fifth gear 171. The number of teeth of the fifth gear 171 is less than the number of teeth of the external gear ring 172.

[0054] For example, the first drive unit 121 and / or the second drive unit 124 may be selected from motors, servos, etc., and no specific limitation is made on the type of drive unit here.

[0055] It is understandable that the fifth gear 171 is driven to rotate by the second drive component 124, which in turn drives the external gear ring 172 and the second planetary carrier 165 to rotate, thereby enabling the first planetary carrier 163 to drive the main shaft 122 to rotate, which facilitates the steering wheel 123 to return to center (i.e., the steering wheel 123 is reset to the state when the vehicle is driving straight).

[0056] Furthermore, since the electromagnetic clutch 130 can provide a larger transmission ratio when energized to meet the user's demand for force feedback, the transmission ratio between the outer gear ring 172 and the fifth gear 171 responsible for centering the steering wheel 123 can be designed to be smaller. This can further improve the feeling of effort required for the user to turn the steering wheel 123 in normal driving scenarios, thereby further enhancing the handling feel of the steering wheel device 100.

[0057] like Figure 3 and Figure 4 As shown, the fourth gear 152 is further rotatably connected to the second planetary carrier 165. This facilitates the installation of the fourth gear 152, helps improve the stability of the fourth gear 152, and does not affect the relative rotation between the fourth gear 152 and the second planetary carrier 165.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments, the body 110 includes a housing 111 and a mounting bracket 112. The main shaft 122 passes through the housing 111. The mounting bracket 112, the first drive member 121 and the electromagnetic clutch 130 are all located inside the housing 111. The mounting bracket 112 is fixedly connected to the housing 111. The first drive member 121 and the electromagnetic clutch 130 are both disposed on the mounting bracket 112.

[0059] Understandably, the mounting bracket 112 facilitates the installation of the first drive component 121 and the electromagnetic clutch 130. The housing 111 provides a safe environment for the mounting bracket 112, the first drive component 121, and the electromagnetic clutch 130, thereby protecting the various components.

[0060] It should be noted that when the steering wheel device 100 is equipped with a first transmission mechanism 140, a second transmission mechanism 150, a third transmission mechanism 160, a fourth transmission mechanism 170, and a second drive member 124, the first transmission mechanism 140, the second transmission mechanism 150, the third transmission mechanism 160, the fourth transmission mechanism 170, and the second drive member 124 are all located inside the housing 111 so as to protect the above-mentioned mechanisms and components through the housing 111.

[0061] For example, in the steering wheel device 100 provided in this embodiment, the first gear 141 has 22 teeth, the second gear 142 has 60 teeth, the third gear 151 has 13 teeth, the fourth gear 152 has 57 teeth, the sun gear 161 has 12 teeth, each planetary gear 164 has 24 teeth, the inner gear ring 162 has 60 teeth, the outer gear ring 172 has 102 teeth, and the fifth gear 171 has 14 teeth. Of course, the combination of the number of teeth of the various toothed components is not limited to this, and no specific limitation is made here.

[0062] To address the aforementioned technical problems, embodiments of this application also provide a vehicle simulator, including a display device, a foot pedal device, a seat device, and a steering wheel device 100 in any of the above embodiments.

[0063] It is understood that since the vehicle simulator provided in this embodiment has the steering wheel device 100 in any of the above embodiments, it has all the beneficial effects of the steering wheel device 100, which will not be described in detail here.
