Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features.

[0021] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0022] By setting up a steer-by-wire feel simulator, some of the mechanical connecting parts between the steering wheel and the steering wheels can be replaced, eliminating these parts and reducing the complexity of the steering system layout. Limiting the number of steering wheel rotations requires setting limiters to restrict the extreme positions of the rotation axis.

[0023] However, the trajectory of the elastic element may be different each time it undergoes elastic deformation, resulting in inconsistent damping force each time the steering wheel is turned to its limit position.

[0024] Among them, the hand-feel limit component transmits the damping torque that can be felt by the operator's hand to the steering wheel through the rotation component.

[0025] To address the technical problem of inconsistent damping force caused by inconsistent deformation trajectories of the elastic element, the first embodiment of this application provides a steer-by-wire feel simulator. (See also...) Figure 1 The steer-by-wire simulator includes a rotating assembly 100 and a limiting assembly 200. The rotating assembly 100 is used to connect to a steering wheel. The limiting assembly 200 includes a guide member 210 and an elastic member 220. The guide member 210 has a guide cavity 211 with an opening. The elastic member 220 is disposed in the guide cavity 211 and partially exposed in the opening. The elastic member 220 is configured to limit the rotation of the rotating assembly 100 in the rotation direction Y. It is understood that the rotating assembly 100 can connect to the steering wheel. When the steering wheel is turned by the operator, the torque of the steering wheel can be transmitted to the rotating assembly 100, causing the rotating assembly 100 to rotate. After the rotating assembly 100 contacts the elastic member 220 and continues to rotate, the elastic member 220 can be compressed in the rotation direction Y and undergo elastic deformation. The reaction force of the elastic member 220 on the rotating assembly 100 is the damping force.

[0026] In some embodiments, the transmission ratio between the steering wheel and the rotation assembly 100 is one; in some embodiments, the transmission ratio between the steering wheel and the rotation assembly 100 is greater than one.

[0027] Specifically, a portion of the elastic element 220 is exposed in the opening so that the elastic element 220 can contact the rotating assembly 100 outside the guide cavity 211.

[0028] It is understandable that the cavity wall of the guide cavity 211 can limit the elastic deformation path of the elastic element 220 by contacting the elastic element, so as to limit and constrain the elastic element 220.

[0029] Firstly, in the above embodiments, the rotating assembly 100 can receive the input torque of the steering wheel and rotate; the guide member 210 provides an installation space for the elastic member 220 through the guide cavity 211 provided inside it, and defines the relative positional relationship between the elastic member 220 and the rotating assembly 100, so that the rotating assembly 100 and the elastic member 220 can contact each other at a preset position, reducing the possibility of inconsistent damping force caused by different contact positions after the steering assembly and the elastic member 220 contact each other.

[0030] Secondly, in the above embodiment, the cavity wall of the guide cavity 211 can also limit and constrain the elastic element 220 during the compression and rebound process, to prevent the elastic element 220 from undergoing unexpected lateral bending, buckling, or dislodgement, ensuring that the elastic element 220 can only be compressed or rebound along the preset rotation direction Y path, further improving the stability and service life of the steer-by-wire feel simulator. Simultaneously, limiting the elastic deformation of the elastic element 220 also allows the elastic potential energy of the elastic element 220 to be converted into a rotation direction Y torque that pushes the rotating component 100 to reset, improving the conversion rate of elastic potential energy and thus enhancing the response sensitivity of the steer-by-wire feel simulator. Furthermore, it also allows the elastic element 220 to return to its initial position after rebound, preparing for the next compression.

[0031] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 6 The rotating assembly 100 includes a rotating shaft 110 and a first connecting member 120. The rotating shaft 110 can be connected to a steering wheel. The first connecting member 120 includes a first connecting portion 121, a second connecting portion 122, and a third connecting portion 123. The first connecting portion 121 is sleeved on the rotating shaft 110. The second connecting portion 122 is radially opposite to the rotating shaft 110 from the first connecting portion 121 along the X direction. The third connecting portion 123 is connected to the second connecting portion 122 along the Z direction. The third connecting portion 123 can contact the elastic member 220.

[0032] In some embodiments, the first connecting portion 121 is interference-fitted with the rotating shaft 110 to achieve axial Z-limiting of the first connecting portion 121 and the rotating shaft 110, as well as torque transmission between the first connecting portion 121 and the rotating shaft 110.

[0033] The second connecting part 122 is connected to the first connecting part 121 on the side opposite to the rotating shaft 110 along the radial direction X, that is, the second connecting part 122 is connected to the outside of the first connecting part 121.

[0034] In the first aspect, in the above embodiment, the first connecting part 121 in the first connector 120 is used to realize the installation and positioning of the first connector 120 and the rotating shaft 110. The sleeve setting can increase the connection area between the first connector 120 and the rotating shaft 110 and improve the connection reliability.

[0035] Secondly, in the above embodiment, the second connecting part 122 is used to achieve radial X offset of the third connecting part 123 so that the distance between the third connecting part 123 and the central axis of the rotating assembly 100 is greater than 0, thereby having an effective lever arm greater than 0, which can transmit torque and reduce the required contact force under the same target torque, which is beneficial to the design of the feel curve and to expanding the selection range of the elastic element 220.

[0036] In addition, by setting the second connecting part 122, the elastic element 220 and the third connecting part 123 can be moved as far away from the central axis as possible in the radial X direction, thereby reducing the proportion of the size of the elastic element 220 in the rotation direction Y in the trajectory of the third connecting part 123 in the rotation direction Y, so that the steer-by-wire feel simulator has a larger stroke under the premise of using the same elastic element 220.

[0037] Thirdly, in the above embodiments, the third connecting portion 123 is used to contact the elastic member 220 to limit the rotation assembly 100 at its extreme position.

[0038] In some embodiments, please refer to Figure 3 , Figure 4 and Figure 5 The elastic element 220 includes a spring 221 and a contact block 222. The spring 221 is disposed in the guide cavity 211. The contact block 222 passes through the guide cavity 211, and a portion of the contact block 222 is exposed in the guide cavity 211. Along the rotation direction Y, one end of the contact block 222 is connected to the spring 221, and the other end of the contact block 222 can contact the rotating assembly 100.

[0039] In the above embodiment, by dividing the elastic element 220 into a contact block 222 and a spring 221, the contact block 222, which is the direct force-bearing medium, can be made of wear-resistant material to withstand the contact stress and friction generated by the reciprocating motion of the rotating assembly 100, reduce the influence of friction and lateral shear force on the spring 221 from the rotating assembly 100, and extend the service life of the spring 221.

[0040] In addition, the contact block 222 can evenly distribute the local contact force applied by the rotating component 100 to the end face of the spring 221, reducing the possibility of elastic deformation caused by uneven force on the end face of the spring 221, so that the spring 221 can generate elastic deformation according to the preset trajectory, thereby making the damping force formed by the elastic element 220 more consistent and the feel better.

[0041] In some embodiments, please refer to Figure 4 The contact block 222 has a positioning groove 224 on the side opposite to the spring 221 along the rotation direction Y, and part of the rotating assembly 100 can enter the positioning groove 224.

[0042] In the above embodiment, the positioning groove 224 provides a defined contact position, ensuring that the contact position of the rotating component 100 and the limiting component 200 is the same each time. This makes the reaction force torque curve output by the limiting component 200 more consistent each time the rotating component 100 rotates to its limit position, resulting in a better and more consistent feel. Simultaneously, it also reduces the relative sliding along the radial X direction after the third connecting part 123 and the contact part come into contact, improving the smoothness of the contact establishment process and reducing the possibility of fluctuations in feel and abnormal noises caused by relative sliding.

[0043] In some embodiments, the third connecting portion 123 is a columnar structure extending along the Z-axis, and the positioning groove 224 is a groove extending along the Z-axis, the groove wall of which can fit against the cylindrical surface of the columnar structure. In some embodiments, the third connecting portion 123 is a cylinder extending along the Z-axis, and the groove wall of the positioning groove 224 is a portion of the cylindrical surface extending along the Z-axis. In some embodiments, the connecting portion is a quadrangular prism extending along the Z-axis, and the groove wall of the positioning groove 224 is formed by the intersection of multiple planes extending along the Z-axis. See also... Figure 4 Along the direction from the contact block 222 to the spring 221, the size of the positioning groove 224 gradually decreases in the radial direction X, so that the positioning groove 224 has a guiding function. After the third connecting part 123 contacts the groove wall of the positioning groove 224, it can guide the third connecting part 123 to a preset position, complete the connection between the third connecting part 123 and the contact block 222, and reduce the possibility of misalignment between the third connecting part 123 and the contact block 222 in the radial direction X.

[0044] In some embodiments, please refer to Figure 3 The elastic element 220 includes at least two contact blocks 222, and the at least two contact blocks 222 include a first contact block 227 and a second contact block 228. The first contact block 227 and the second contact block 228 are respectively connected to the two ends of the spring 221 along the rotation direction Y.

[0045] In the above embodiment, by respectively providing a first contact block 227 and a second contact block 228 at both ends of a spring 221, bidirectional limiting of the rotating assembly 100 in the rotation direction Y is achieved. When the rotating assembly 100 rotates in either direction in the rotation direction Y, that is... Figure 3In either the clockwise or counterclockwise direction, the mechanism only contacts and presses one of the contact blocks 222, transmitting the force to the spring 221, thus simulating the steering resistance in that direction. Using only one spring 221 to achieve limit movement in both directions ensures that the damping force received by the rotating component 100 at both extreme positions is generated by the same spring 221, allowing the rotating component 100 to receive the same damping force at both extreme positions, resulting in a better feel.

[0046] In some embodiments, please refer to Figure 4 The guide member 210 has a mounting cavity 213 and a mounting hole 212. The spring 221 is disposed in the mounting cavity 213, and the contact block 222 passes through the mounting hole 212, with a portion of the contact block 222 disposed in the mounting hole 212. The guide member 210 has a first surface 214 and a second surface 215 that are opposite to each other along the rotation direction Y. The second surface 215 is used to surround and form the mounting cavity 213. The mounting hole 212 passes through the first surface 214 and the second surface 215 and communicates with the mounting cavity 213 to form a guide cavity 211. The second surface 215 can be connected to the spring 221 to limit the elastic member 220 along the rotation direction Y.

[0047] In some embodiments, the mounting hole 212 extends along the rotational direction Y, and the mounting cavity 213 extends along the rotational direction Y.

[0048] In some embodiments, the guide member 210 has two mounting holes 212, the mounting cavity 213 is connected between the two mounting holes 212, and the two ends of the spring 221 along the rotation direction Y are in contact with the two second surfaces 215 respectively.

[0049] Specifically, the area of ​​the mounting hole 212 is smaller than the area of ​​the mounting cavity 213, so that the guide 210 has a second surface 215.

[0050] In the above embodiment, the mounting cavity 213 is used to accommodate and constrain the spring 221, and the mounting hole 212 is used to accommodate the contact block 222 and guide the contact block 222, so that the mounting position and movement boundary of the elastic element 220 can be constrained.

[0051] Meanwhile, the second surface 215 limits the rotation direction Y of the spring 221, making the rotation direction Y position of the elastic element 220 more stable during operation, reducing the possibility of the elastic element 220 shifting in the rotation direction Y, thereby helping to improve the controllability of the contact establishment and force transmission process, as well as the consistency and stability of the reaction torque output.

[0052] In some embodiments, the contact block 222 includes a first contact portion 223, a fourth connecting portion 225, and a second contact portion 226. Along the rotation direction Y, the first contact portion 223 is located on the side of the first surface 214 opposite to the second surface 215. The first surface 214 can contact the first contact portion 223 to limit the first contact portion 223. The fourth connecting portion 225 passes through the mounting hole 212 and is connected to the first contact portion 223. The second contact portion 226 is disposed in the mounting cavity 213 and is connected to the fourth connecting portion 225. The second surface 215 can contact the second contact portion 226 to limit the second contact portion 226.

[0053] In some embodiments, the first contact portion 223 has a positioning groove 224 on the side opposite to the second contact portion 226 along the rotation direction Y.

[0054] In some embodiments, the fourth connecting portion 225 extends along the rotational direction Y.

[0055] Specifically, along the rotation direction Y, the projected area of ​​the first contact portion 223 and the second contact portion 226 is greater than the projected area of ​​the mounting hole 212, so that the first contact portion 223 and the second contact portion 226 cannot pass through the mounting hole 212, thereby allowing the first contact portion 223 and the second contact portion 226 to be limited by the first surface 214 and the second surface 215 respectively.

[0056] In the above embodiment, by providing a fourth connecting portion 225 in the mounting hole 212 and enabling the first surface 214 and the second surface 215 to limit the rotation direction Y of the first contact portion 223 and the second contact portion 226 respectively, the position of the contact block 222 along the axial direction Z in the guide member 210 can be constrained, and it can be in the same position after each release of elastic potential energy, so as to prepare for the next contact with the rotating component 100, and to unify the position and feel when the rotating component 100 contacts the contact block 222 each time.

[0057] In some embodiments, please refer to Figure 2 and Figure 5 The steer-by-wire simulator also includes a first housing 300, which has a bottom wall 310 and a side wall 320. The bottom wall 310 and the side wall 320 are connected to form a receiving cavity 330. At least a portion of the rotating assembly 100 is disposed in the receiving cavity 330. A limiting assembly 200 is disposed in the receiving cavity 330. A guide 210 is connected to the bottom wall 310, and / or the guide 210 is connected to the side wall 320.

[0058] In some embodiments, the guide 210 is connected to the bottom wall 310 and spaced apart from the side wall 320.

[0059] In the above embodiment, the bottom wall 310 can provide axial Z support for the guide 210, reducing the possibility of misalignment of the rotating component 100 and the limiting component 200 in the axial Z direction due to installation deviation, thereby improving the consistency of damping force when the rotating component 100 and the limiting component 200 come into contact each time.

[0060] In some embodiments, the guide 210 is connected to the sidewall 320 and spaced apart from the bottom wall 310.

[0061] In the above embodiment, the bottom wall 310 can provide radial X support for the guide 210, reducing the possibility of misalignment of the rotating component 100 and the limiting component 200 in the radial X due to installation deviation, thereby improving the consistency of damping force when the rotating component 100 and the limiting component 200 come into contact each time.

[0062] In some embodiments, the guide 210 is connected to the bottom wall 310 and the side wall 320, respectively.

[0063] In the above embodiments, the guide member 210 can be supported in the axial Z and radial X directions, which can simultaneously reduce the possibility of misalignment between the rotating component 100 and the limiting component 200 in the axial Z and radial X directions due to installation deviations, thereby improving the consistency of the damping force each time the rotating component 100 contacts the limiting component 200.

[0064] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 5 The guide member 210 is connected to the bottom wall 310. The guide member 210 includes a second housing 216, a third housing 217, and a second connector 218. The third housing 217 and the second housing 216 are connected and surround to form a guide cavity 211. The second connector 218 passes through the second housing 216, the third housing 217, and the bottom wall 310, and connects the second housing 216, the third housing 217, and the bottom wall 310.

[0065] Firstly, in the above embodiments, the guide member 210 adopts a split design, with the second housing 216 and the third housing 217 connected to form an internal guide cavity 211, so that the contact block 222 with a larger radial X outer dimension can be installed in the mounting hole 212 with a smaller diameter, reducing the assembly difficulty of the contact block 222 and the guide member 210.

[0066] Secondly, in the above embodiments, the assembly method in which the second connector 218 passes through the second housing 216 and the third housing 217 and connects to the bottom wall 310 can clamp the first housing 300 and the second housing 216 between the second connector 218 and the bottom wall 310, improving the connection stability between the guide 210 and the first housing 300. Simultaneously, the reaction force exerted by the spring 221 on the second housing 216 and the third housing 217 can also be transmitted to the bottom wall 310 through the second connector 218, further reducing the possibility of displacement or loosening of the guide 210 under high loads, and improving the stability of the steer-by-wire simulator.

[0067] In some embodiments, the second connector 218 is a bolt.

[0068] Accordingly, this application also provides a vehicle including a steer-by-wire feel simulator as described in any of the above embodiments.
