[0054] Figure 1 A schematic diagram of the three-dimensional structure of a simulation device provided in some embodiments of the present application is shown; Figure 2 A schematic diagram of the three-dimensional structure of a simulation device provided by some embodiments of the present application from another perspective is shown; for ease of explanation, only the content related to the embodiments of the present application is shown.

[0055] Please refer to Figure 1 and Figure 2 A simulation device provided in an embodiment of the present application includes a plurality of transmission shafts 110 , a plurality of transmission assemblies 120 and four limit members 130 .

[0056] A plurality of transmission components 120 are matched with a plurality of transmission shafts 110 so that the plurality of transmission shafts 110 can be sequentially driven according to a transmission sequence. Along the transmission sequence, the preceding transmission shaft 110 and the following transmission shaft 110 are connected by a transmission component 120, the first transmission shaft 110 is a first transmission shaft 111, and the first transmission shaft 111 is used to connect the steering wheel, and the transmission shafts 110 other than the first transmission shaft 110 among the plurality of transmission shafts 110 are second transmission shafts 112, and the rotation axes of the plurality of transmission shafts 110 are parallel to each other.

[0057] The plurality of transmission components 120 are matched with the plurality of transmission shafts 110. It can be understood that the plurality of transmission components 120 are matched and connected with the plurality of transmission shafts 110. According to different structural forms of the transmission components 120, there can be different matching and connecting modes, so that the plurality of transmission shafts 110 can be sequentially transmitted according to the transmission sequence. The transmission sequence can refer to a pre-set sequence for power transmission between the plurality of transmission shafts 110. Along the transmission sequence, the front transmission shaft 110 and the rear transmission shaft 110 are connected in transmission by means of a transmission component 120. It can be understood that the power of the front transmission shaft can be transmitted to the rear transmission shaft 110 through the transmission component 120.

[0058] It should be noted that the number of transmission components 120 can be set to 2, 3 or 4, etc., and the number of transmission shafts 110 can also be 2, 3 or 4, etc., which can be set according to actual conditions, and the embodiment of the present application does not impose specific restrictions on this. Figure 1 As shown, there are two transmission assemblies 120 and three transmission shafts.

[0059] The first transmission shaft 111 is connected to the steering wheel, that is, when the steering wheel is turned, the first transmission shaft 111 can also rotate, and the power of the first transmission shaft 111 can be transmitted to the next transmission shaft 110 through a transmission assembly 120 .

[0060] There are four limiters 130, two of which are disposed on the first transmission shaft 111, and the other two of which are disposed on the second transmission shaft 112. The limiter 130 includes a connecting portion 131 connected to the corresponding transmission shaft 110 and a limiter 132 disposed on the connecting portion 131.

[0061] The connecting portion 131 may refer to a portion connected to the corresponding transmission shaft 110 , and the limiting portion 132 may refer to a component capable of limiting the rotation of the transmission shaft 110 .

[0062] Two of the limit members 130 are arranged on the first transmission shaft 111 and the other two of the limit members 130 are arranged on the second transmission shaft 112. It can be understood that two of the limit members 120 can rotate with the rotation of the first transmission shaft 111, and the other two of the limit members 130 can rotate with the rotation of the second transmission shaft 112.

[0063] The rotation paths of the two limiting portions 132 disposed on the first transmission shaft 111 are different from each other, and the rotation paths of the two limiting portions 132 disposed on the second transmission shaft 112 are different from each other.

[0064] One of the limiting portions 132 provided on the second transmission shaft 112 is located on the rotation path of one of the limiting portions 132 provided on the first transmission shaft 111, so that the first transmission shaft 111 has a first limit rotation position. Another of the limiting portions 132 provided on the second transmission shaft 112 is located on the rotation path of another of the limiting portions 132 provided on the first transmission shaft 111, so that the first transmission shaft 111 has a second limit rotation position.

[0065] The rotation paths of the two limit portions 132 disposed on the first transmission shaft 111 are different from each other. It can be understood that when the two limit portions 132 rotate with the first transmission shaft 111, the paths that the two limit portions 132 pass through during the rotation process are different. Similarly, the rotation paths of the two limit portions 132 disposed on the second transmission shaft 112 are also different from each other. It can be understood that when the two limit portions 132 rotate with the second transmission shaft 112, the paths that the two limit portions 132 pass through during the rotation process are different.

[0066] One of the limiting parts 132 on the second transmission shaft 112 is located on the rotation path of one of the limiting parts 132 on the first transmission shaft 111. When the first transmission shaft 111 rotates in one direction, one of the limiting parts 132 on the first transmission shaft 111 rotates along with the first transmission shaft 111, and the second transmission shaft 112 can also rotate, so that one of the limiting parts 132 on the second transmission shaft 112 also rotates. After the first transmission shaft 111 rotates a certain angle, one of the limiting parts 132 on the second transmission shaft 112 can abut against one of the limiting parts 132 on the first transmission shaft 111, so that the first transmission shaft 111 can no longer rotate, and the first transmission shaft 111 is in the first limit rotation position. Similarly, another of the limiting portions 132 on the second transmission shaft 112 is located on the rotation path of another of the limiting portions 132 on the first transmission shaft 111. When the first transmission shaft 111 rotates in another direction, the process is similar to the process of the first transmission shaft 111 rotating in one direction mentioned above, and will not be described in detail here. After the first transmission shaft 111 rotates a certain angle, another of the limiting portions 132 on the second transmission shaft 112 can abut against another of the limiting portions 132 on the first transmission shaft 111, so that the first transmission shaft 111 can no longer rotate, and the first transmission shaft is in the second extreme rotation position.

[0067] Figure 3 A schematic diagram showing a structure of a simulation device provided by some embodiments of the present application in a certain position; Figure 4 The schematic diagram of the structure of the simulation device provided in some embodiments of the present application is shown in another position. Figure 3 As shown, it is indicated that Figure 3 For example, the first transmission shaft 111 rotates clockwise, and the two limit portions 132 contact and collide, so that the first transmission shaft 111 reaches the first limit rotation position. Figure 4 As shown, it is indicated that Figure 4 For example, the first transmission shaft 111 rotates counterclockwise, and the two limit portions 132 contact and collide, so that the first transmission shaft 111 reaches the second limit rotation position.

[0068] Thus, by providing multiple transmission shafts 110 and multiple transmission assemblies 120, and multiple transmission assemblies 120 are matched to multiple transmission shafts 110, multiple transmission shafts 110 can be sequentially transmitted according to the transmission sequence, so that the power of the previous transmission shaft 110 can be more stably transmitted to the next transmission shaft 110, and the rotation axes of the multiple transmission shafts 110 are parallel to each other, which can make the rotation of each transmission shaft 110 more stable during the transmission process, thereby improving the reliability of the device. In addition, by providing four limit members 130, and one of the limit parts 132 on the second transmission shaft 112 is located on the rotation path of one of the limit parts 132 on the first transmission shaft 111, and another of the limit parts 132 on the second transmission shaft 112 is located on the rotation path of another of the limit parts 132 on the first transmission shaft 111, the first transmission shaft 111 has a first limit rotation position and a second limit rotation position during the rotation in two directions, thereby more accurately controlling the rotation range of the steering wheel and improving the realism of the simulated driving.

[0069] In some embodiments, please refer to Figure 1 and Figure 2 The connecting portion 131 is sleeved on the corresponding transmission shaft 110 , and the limiting portion 132 is disposed on the peripheral side of the connecting portion 131 .

[0070] Specifically, the connecting portion 131 is sleeved on the corresponding transmission shaft 110. It can be understood that the connecting portion 131 has a hole-shaped structure that matches the size and shape of the transmission shaft 110, and the transmission shaft 110 can pass through the structure. The limiting portion 132 is arranged on the peripheral side of the connecting portion 131. It can be understood that when the connecting portion 131 is sleeved on the transmission shaft 110 and rotates with the transmission shaft, the limiting portion 132 can also rotate around the transmission shaft 110.

[0071] In this way, by sleeve-fitting the connection part 131 on the corresponding transmission shaft 110, and arranging the limiting part 132 on the peripheral side of the connection part 131, the connection part 131 can be more closely fitted with the transmission shaft 110, and can rotate with the transmission shaft 110. At the same time, arranging the limiting part 132 on the peripheral side of the connection part 131 can also make full use of the space around the transmission shaft 110 to realize the limiting function, thereby improving the reliability of the device.

[0072] In some embodiments, please refer to Figure 1 and Figure 2 The limiting portion 132 is longitudinally extended from the peripheral side of the connecting portion 131 in a direction away from the rotation axis of the corresponding transmission shaft 110 along the radial direction of the corresponding transmission shaft 110 .

[0073] It should be noted that the radial length of the limiting portion 132 along the corresponding transmission shaft 110 can be set to be greater than the width of the limiting portion 132 along the direction of the rotation axis of the corresponding transmission shaft 110, so that the position of the limiting portion 132 is more compact.

[0074] Specifically, the radial direction of the transmission shaft 110 may refer to a straight line direction perpendicular to the rotation axis of the transmission shaft 110. The limiting portion 132 is longitudinally extended from the peripheral side of the connecting portion 131 in the radial direction of the corresponding transmission shaft 110 toward the direction away from the rotation axis of the corresponding transmission shaft 110. It can be understood that the limiting portion 132 has a length in the direction away from the rotation axis of the corresponding transmission shaft 110, and the length can be set according to actual conditions, and the embodiment of the present application does not impose specific restrictions on this.

[0075] In this way, by extending the limiting portion 132 longitudinally along the radial direction of the corresponding transmission shaft 110 from the circumferential side of the connecting portion 131 toward the direction away from the rotation axis of the corresponding transmission shaft 110, the limiting portions 132 on two different transmission shafts 110 and extending in the same plane can contact each other after rotating to a certain angle, thereby more stably preventing the rotation of the transmission shaft 110 and more accurately controlling the rotation range of the steering wheel.

[0076] In some embodiments, please refer to Figure 1 , a plurality of second transmission shafts 112 are provided.

[0077] Specifically, the two stoppers 130 provided on the second transmission shaft 112 are both provided on the same second transmission shaft 112. Of the two stoppers 130 provided on the second transmission shaft 112, the direction in which one stopper 130 points to the other stopper 130 intersects with the extension direction of the rotation axis of the second transmission shaft 112.

[0078] It should be noted that the number of the second transmission shafts 112 can be 2 or 3, and can be set according to actual conditions, and is not specifically limited here. Figure 1As shown, two second transmission shafts 112 are provided, the first transmission shaft 111 and one of the second transmission shafts 112 are transmission-connected by means of a transmission assembly 120, and one of the second transmission shafts 112 and another of the second transmission shafts are transmission-connected by means of another transmission assembly 120. In addition, in some other embodiments, the two stoppers 130 provided on the second transmission shafts 112 may also be provided on different second transmission shafts 112, and may be provided according to actual conditions, and no specific limitation is made here.

[0079] Among the two limit members 130 provided on the second transmission shaft 112, the direction in which one of the limit members 130 points to the other limit member 130 intersects with the extension direction of the rotation axis of the second transmission shaft 112. It can be understood that the direction in which one of the limit members 130 points to the other limit member 130 and the extension direction of the rotation axis of the second transmission shaft 112 are not perpendicular to each other.

[0080] Thus, by providing a plurality of second transmission shafts 112, and both of the two stoppers 130 provided on the second transmission shaft 112 are provided on the same second transmission shaft 112, the stoppers 130 of the entire device can be made more compact, thereby better achieving the function of stoppering. At the same time, compared with providing a single second transmission shaft 112, providing a plurality of second transmission shafts 112 can also improve the transmission efficiency of the simulation device, which is conducive to improving the stability and reliability of the device.

[0081] In some embodiments, please refer to Figure 1 and Figure 2 Alternatively, the connection parts 131 of the two stoppers 130 disposed on the second transmission shaft 112 are an integrated structure; or, the connection parts 131 of the two stoppers 130 disposed on the second transmission shaft 112 are independent of each other.

[0082] Specifically, the connection parts 131 of the two stoppers 130 provided on the second transmission shaft 112 can be provided as an integrated structure by welding, fusing or integral molding. Alternatively, the connection parts 131 of the two stoppers 130 provided on the second transmission shaft 112 are independent of each other, and the two connection parts 131 are independent of each other and can be installed on the second transmission shaft 112 respectively.

[0083] In this way, the connecting portion 131 of the two limit members 130 of the second transmission shaft 112 is an integrated structure. When one of the limit members 130 on the second transmission shaft 112 contacts and collides with one of the limit members 130 on the first transmission shaft 111, the integrated connection portion 131 can reduce the concentration of stress. At the same time, the setting of the integrated connection portion 131 can also facilitate production, which helps to improve production efficiency. Alternatively, the connecting portions 131 of the two limit members 130 of the second transmission shaft 112 are set to be independent of each other. When the limit members 130 are used for a long time to limit and collide, resulting in an error in the limit rotation angle between the limit members 130, the position of the limit member 130 can be adjusted more conveniently, thereby improving the accuracy of the limit rotation angle. It can also be convenient for maintenance and replacement, thereby improving the maintainability of the device.

[0084] In some embodiments, please refer to Figure 1 and Figure 2 , define the plane where the rotation axis of the first transmission shaft 111 is located as the reference plane. Two second transmission shafts 112 are provided, and the two second transmission shafts 112 are arranged on both sides of the reference plane along the first direction F1, and the first direction F1 is perpendicular to the reference plane.

[0085] It can be understood that, when two second transmission shafts 112 are provided, the two second transmission shafts 112 are respectively arranged on both sides of the first transmission shaft 111 along the first direction F1. Figure 1 , which illustrates a situation where two second transmission shafts 112 are arranged on both sides of the reference plane along the first direction F1.

[0086] Thus, by providing two second transmission shafts 112 and arranging the two second transmission shafts 112 on both sides of the reference plane along the first direction F1, the distribution of the first transmission shaft 111 and the second transmission shaft 112 can be made more reasonable, making the space of the simulation device 100 more compact and reasonable.

[0087] In some embodiments, please refer to Figure 1 and Figure 2 , the first second transmission shaft 112 located after the first transmission shaft 111 along the transmission sequence is the target transmission shaft, and the transmission assembly 120 connected between the first transmission shaft 111 and the target transmission shaft is the first transmission assembly 121. The first transmission assembly 121 includes a first gear 121a provided on the first transmission shaft 111, and a second gear 121b provided on the target transmission shaft. The first gear 121a is meshedly connected with the second gear 121b.

[0088] Specifically, when the first transmission shaft 111 rotates, the first gear 121a on the first transmission shaft 111 may also rotate accordingly, and the first gear 121a and the second gear meshing 121b transmit the rotational power of the first gear 121a to the second gear 121b, and the second gear 121b drives the target transmission shaft to rotate.

[0089] It should be noted that the size and number of the first gear 121a and the second gear 121b can be set according to actual conditions, and the present application does not impose specific restrictions on this. In addition, the material of the first gear 121a and the second gear 121b can be a material with high strength such as steel, which is convenient for long-term use, can improve the stability and durability of the transmission assembly 120, and reduce the cost of maintenance and replacement.

[0090] In this way, by connecting the first transmission assembly 121 between the first transmission shaft 111 and the target transmission shaft, the rotational power of the first transmission shaft 111 can be more smoothly transmitted to the target shaft. At the same time, the first transmission assembly 121 is configured to include a first gear 121a and a second gear 121b, and the first gear 121a and the second gear 121b are meshed and connected, so that the power of the first transmission shaft 111 can be more smoothly and accurately transmitted to the target transmission shaft.

[0091] In some embodiments, please refer to Figure 1 and Figure 2 The second transmission shaft 112 is provided with a plurality of transmission components 120, and the transmission component 120 connected between two adjacent second transmission shafts 112 along the transmission sequence is the second transmission component 122. The second transmission component includes a first transmission wheel 122a, a second transmission wheel 122b, and a first transmission member 122c wound around the first transmission wheel 122a and the second transmission wheel 122b. The first transmission wheel 122a and the second transmission wheel 122b are provided on two adjacent second transmission shafts 112 in a one-to-one correspondence.

[0092] Specifically, after the first transmission shaft 111 transmits power to the subsequent second transmission shaft 112, the subsequent second transmission shaft 112 rotates and drives the first transmission wheel 122a to rotate, thereby causing the first transmission member 122c to rotate, and the first transmission member 122c transmits the rotational power to the second transmission wheel 122b, thereby causing the second transmission shaft 112 adjacent to the subsequent second transmission shaft 112 to rotate.

[0093] It should be noted that the first transmission member 122c can be a belt or a chain, and can be configured according to actual conditions. The embodiment of the present application does not impose any specific limitation on this.

[0094] In this way, by setting up multiple second transmission shafts 112, and two adjacent second transmission shafts 112 are connected through the second transmission assembly 122, the first transmission member 122c is wound around the first transmission wheel 122a and the second transmission wheel 122b, so that the rotational power can be transmitted more stably between the two adjacent second transmission shafts 112, thereby improving the reliability of the device and the accuracy of the simulated driving.

[0095] In some embodiments, please refer to Figure 1 and Figure 2 The simulation device 100 further includes a detection member 140 connected to the first transmission shaft 111 .

[0096] The detection member 140 is used to detect the rotation angle of the first transmission shaft 111. Specifically, the detection member 140 is coupled to the first transmission shaft 111, and when the first transmission shaft 111 rotates, the detection member 140 can detect the rotation angle of the first transmission shaft. In addition, the detection member 140 can be electrically connected to the controller, and after the detection member 140 detects the rotation angle of the first transmission shaft 111, the detection member 140 can feed back the rotation angle to the controller in real time.

[0097] In this way, the detection member 140 is provided to more accurately detect the rotation angle of the first transmission shaft 111, and then obtain the rotation angle of the steering wheel, so as to more accurately present the steering action, angle, etc. during the simulated driving process, making the simulated driving experience more realistic.

[0098] In some embodiments, please refer to Figure 1 and Figure 2 The simulation device 100 also includes a transmission mechanism 150 .

[0099] The detection member 140 has an output shaft 141. The transmission mechanism 150 includes a third transmission wheel 151, a fourth transmission wheel 152, and a second transmission member 153 wound around the third transmission wheel 151 and the fourth transmission wheel 152. The third transmission wheel 151 and the fourth transmission wheel 152 are disposed on the first transmission shaft 111 and the output shaft 141 in a one-to-one correspondence.

[0100] Specifically, when the first transmission shaft 111 rotates, the third transmission wheel 151 provided on the first transmission shaft 111 also rotates, driving the second transmission member 153 to rotate, so that the fourth transmission wheel 152 rotates, driving the output shaft 141 of the detection member 140 to rotate, so that the detection member 140 can detect the rotation angle of the first transmission shaft 111.

[0101] In this way, by setting up the transmission mechanism 150, the first transmission shaft 111 and the output shaft 141 of the detection member 140 are connected by the third transmission wheel 151, the fourth transmission wheel 152 and the second transmission member 153 arranged around the third transmission wheel 151 and the fourth transmission wheel 152, so that the detection member 140 can more stably and accurately detect the rotation angle of the first transmission shaft 111.

[0102] In some embodiments, please refer to Figure 1 , the detection member 140 is configured as an absolute encoder.

[0103] Specifically, an absolute encoder is a sensor used to more accurately measure the rotation angle or linear displacement. An absolute encoder can determine the position by using different encoding methods on the code disk. There are multiple concentric code tracks on the code disk, and each code track is divided into many small segments. These small segments represent the binary numbers "0" and "1" by means of light-transmitting and light-opaque areas (optical encoders) or magnetic change areas (magnetic encoders). When the first transmission shaft 111 rotates, the code disk of the absolute encoder is driven to rotate together. The photoelectric detection element (optical) or magnetic sensitive element (magnetic) inside the encoder can read the encoding information at different positions on the code disk. Since each position has a unique code, the encoder can determine the current position of the code disk and then determine the rotation angle of the first transmission shaft 111 regardless of whether it is just powered on or at any time during the movement.

[0104] In this way, by configuring the detection member 140 as an absolute encoder, the rotation angle of the first transmission shaft 111 can be detected more accurately and stably.

[0105] Figure 5 Some other three-dimensional structural schematic diagrams of simulation devices provided by some embodiments of the present application are shown; for the convenience of explanation, only the contents related to the embodiments of the present application are shown.

[0106] In some embodiments, please refer to Figure 1 , and combined with reference Figure 5 The simulation device 100 further includes a driving member 160 , which is transmission-connected to the first transmission shaft 111 .

[0107] In which, the driving member 160 is configured to be able to drive the first transmission shaft 111 to rotate along a first rotation direction and a second rotation direction around the central axis of the first transmission shaft 111, and the first rotation direction and the second rotation direction are opposite; and / or, the simulation device 100 has a use state; in the use state, the first transmission shaft 111 rotates driven by the steering wheel, and the driving member 160 is used to provide a damping force to the first transmission shaft 111 that is opposite to the rotation direction of the first transmission shaft 111.

[0108] Specifically, when the first transmission shaft 111 rotates to a certain angle, the driver releases the steering wheel, and the steering wheel does not apply external force to the first transmission shaft. The driving member 160 can drive the first transmission shaft 111 to rotate along the first rotation direction and the second rotation direction around the central axis of the first transmission shaft 111, thereby driving the steering wheel to return to the center, simulating the process in which the steering wheel can automatically return to the center after the steering is completed during driving. In the same viewing angle, the first rotation direction can be clockwise, and the second rotation direction can be counterclockwise; in another viewing angle, the first rotation direction can be counterclockwise, and the second rotation direction can be clockwise.

[0109] And / or, the use state of the simulation device 100 may refer to a state in which the driver operates the steering wheel, and the steering wheel rotates to drive the first transmission shaft to rotate. During the rotation of the first transmission shaft 111, the first transmission shaft 111 rotates driven by the steering wheel, and the driving member 160 can be used to provide a damping force opposite to the rotation direction of the first transmission shaft 111 to the first transmission shaft 111. The damping force here can be set to the damping force received by the first transmission shaft 111 when the steering wheel is turned during actual driving, and the direction of the damping force is opposite to the rotation direction of the first transmission shaft 111. For example, when the steering wheel drives the first transmission shaft 111 to rotate clockwise, the driving member 160 can output a counterclockwise torque to the first transmission shaft 111; when the steering wheel drives the first transmission shaft 111 to rotate counterclockwise, the driving member 160 can output a clockwise torque to the first transmission shaft 111, thereby achieving the purpose of simulating the steering resistance actually received during driving.

[0110] In this way, not only can the process of the steering wheel automatically returning to the center position after the steering is completed during the simulated vehicle driving process be realized, but also damping force can be provided to the first transmission shaft 111 during the steering process, thereby solving the problem that the steering wheel force feedback cannot fit the actual driving situation and improving the authenticity of the simulated driving.

[0111] In some embodiments, please refer to Figure 1 The first transmission shaft 111 has an initial position, the rotation angle of the first transmission shaft 111 from the initial position to the first extreme position is a first preset angle, and the rotation angle of the first transmission shaft 111 from the initial position to the second extreme position is a second preset angle, and the first preset angle and the second preset angle are both 540 degrees.

[0112] It is understandable that the initial position of the first transmission shaft 111 is the position where the first transmission shaft 111 is not rotating and is relatively stationary. The rotation angle refers to the angle of the first transmission shaft 111 relative to the initial position during the rotation process.

[0113] The first preset angle and the second preset angle are both set to 540 degrees. It can be understood that whether the first transmission shaft 111 rotates from the initial position to the first extreme position or from the initial position to the second extreme position, the angle of rotation of the first transmission shaft 111 is 540 degrees. That is, in the simulation device 100, when the simulated steering wheel is rotated from the initial position in the middle along the first rotation direction (clockwise) to the first extreme position, and rotated along the second rotation direction (counterclockwise) to the second extreme position, the maximum rotation angle is 540 degrees.

[0114] In this way, the rotation angle of the first transmission shaft 111 from the initial position to the first extreme position is set to the first preset angle, and the rotation angle of the first transmission shaft 111 from the initial position to the second extreme position is set to the second preset angle, which can provide more accurate rotation control for simulated driving and improve the accuracy and realism of simulated driving operations.

[0115] It should be noted that the preset angle can also be 720 degrees, etc., which can be set according to actual conditions and is not specifically limited here.

[0116] In some embodiments, please refer to Figure 1 and Figure 5 The simulation device 100 also includes a shell 170 .

[0117] Specifically, the housing 170 has a receiving cavity Q, all the transmission shafts 110 are rotatably connected to the housing 170 , and all the transmission components 120 and all the limiting members 130 are accommodated in the receiving cavity Q.

[0118] The size and shape of the accommodating cavity Q can be set according to actual conditions and are not specifically limited here.

[0119] All the transmission shafts 110 are rotatably connected to the housing 170. It can be understood that all the transmission shafts 110 can be connected to the housing 170 by means of bearing connection or other connection methods, and can rotate around their own axes. In this way, the transmission shafts 110 can maintain a relatively stable position under the support of the bearings, and can rotate smoothly, reducing the friction and resistance during the rotation process, so that the power can be transmitted in the housing through the transmission shaft when the steering wheel is turned.

[0120] In this way, by setting up the shell, all transmission shafts 110 can be rotatably connected to the shell 170, all transmission components 120 and all limit members 130 are accommodated in the accommodating cavity Q, making the structure of the entire simulation device more compact and orderly.

[0121] Based on the same inventive concept, an embodiment of the present application provides a vehicle simulation system, including a steering wheel and a simulation device as in any of the above embodiments. Specifically, the first transmission shaft 111 is connected to the steering wheel.

[0122] It should be noted that the simulation device 100 can be used for racing simulation experience to simulate the real racing driving experience; it can also be used for car driving games to provide a more realistic and smooth game experience, allowing players to more deeply integrate into the game world; it can also be used in scientific research fields such as vehicle dynamics research and driving behavior analysis to help researchers conduct more in-depth testing and analysis; it can also be used in various virtual driving scenarios, combined with virtual reality (VR) or augmented reality (AR) technology, to provide users with a more immersive simulated driving experience. In addition, the simulation device 100 can adapt to various types of vehicle simulation systems, providing drivers with a wider range of compatibility options.

[0123] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0124] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
