In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0050] like Figures 1 to 4As shown, an embodiment of the present invention provides a steering wheel rotation simulation device for steering by wire, which comprises a cylinder 1, a rotating assembly 2 and a hand-feel simulation motor 3, wherein the rotating assembly 2 comprises a rotating shaft 21 and a telescopic member 22, wherein the rotating shaft 21 and the telescopic member 22 are slidably connected, the rotating shaft 21 is at least partially disposed in the cylinder 1, and the telescopic member 22 is used to connect with the steering wheel. The rotating assembly 2 can serve as a transmission structure between the steering wheel and the hand-feel simulation motor 3, and is connected with the hand-feel simulation motor 3 through the rotating shaft 21 as a connecting structure. The hand-feel simulation motor 3 comprises a rotor 31, a stator 32 and a jacket 33, wherein the stator 32 is arranged along the circumference of the rotating shaft 21 and is fixedly connected with the cylinder 1, that is, the stator 32 can be designed as an annular structure and can be sleeved on the outside of the rotating shaft 21. The rotor 31 is arranged along the circumference of the rotating shaft 21 and is rotatably connected to the cylinder 1, that is, the rotor 31 can be designed as an annular structure and can be sleeved on the outside of the rotating shaft 21, and the stator 32 is sleeved on the outside of the rotor 31. The stator 32 can drive the rotor 31 to rotate after being energized.

[0051] The jacket 33 is arranged along the circumference of the rotating shaft 21, and the jacket 33 has a first end and a second end that are arranged opposite to each other. The first end of the jacket 33 is fixedly connected to the rotating shaft 21, and the second end of the jacket 33 is fixedly connected to the rotor 31. The jacket 33 is extended in the radial direction of the rotating shaft 21 to support the rotor 31 from the surface of the rotating shaft 21, and a receiving space 34 is formed between the rotor 31 and the rotating shaft 21. The receiving space 34 is used for the telescopic member 22 to move in or out, that is, the jacket 33 can be designed as an annular structure and extend in the radial direction of the rotating shaft 21, and the rotor 31 and the stator 32 are supported and supported from the surface of the rotating shaft 21, thereby providing a receiving space 34 for the telescopic member 22, and the rotation of the rotor 31 can drive the rotor 31 through the jacket 33. The shaft 21 rotates, and the telescopic member 22 arranged on the shaft 21 can be moved into or out of the accommodating space 34. The hand-feel simulation motor 3 drives the shaft 21 to rotate through the rotor 31 and the jacket 33, while reducing the occupation of the axial length of the shaft 21 itself, and also reducing the occupation of the telescopic movement range of the telescopic member 22 arranged on the shaft 21, and increasing the telescopic distance of the steering wheel driven by the telescopic member 22 relative to the shaft 21. For example, the telescopic distance can be increased from 80 mm to 120 mm to meet the user's needs for adjusting the telescopic range of the steering wheel, thereby solving the problem that the telescopic adjustable length of the telescopic tube of the automobile wire-controlled steering system in the related art is limited and difficult to meet the user's needs.

[0052] In this embodiment, the rotating shaft 21 and the telescopic member 22 can slide relative to each other but will not rotate relative to each other, so that the rotating shaft 21 can smoothly drive the steering wheel to rotate. For example, the outer wall of the rotating shaft 21 and the inner wall of the telescopic member 22 can be connected by a spline, or the contour shape of the rotating shaft 21 and the telescopic member 22 can be designed as a polygon, while achieving sliding, the telescopic member 22 is prevented from rotating relative to the rotating shaft 21. The rotor 31 and the stator 32 are both hollow annular structures, and the stator 32 may include a connected stator core and a stator winding, and the stator core is a cylindrical structure with a plurality of grooves arranged on the inner wall, and the stator winding is arranged in the groove of the stator core at intervals along the circumference of the stator core. The rotor 31 includes a connected rotor shaft and a plurality of magnets, and the outer wall of the rotor shaft may be provided with a plurality of open grooves in the circumferential direction, and the plurality of magnets are arranged in the open grooves at intervals along the circumferential direction of the outer wall of the rotor shaft.

[0053] like Figure 1 to Figure 2 As well as Figures 5 to 7 As shown, in some embodiments, the telescopic member 22 includes a connecting tube 221 and a sleeve 222, the rotating shaft 21 has a first end and a second end relatively arranged, the first end of the rotating shaft 21 is fixedly connected to the sleeve 33, for example, the sleeve 33 can be sleeved and fixedly connected to the outer circumference of the first end of the rotating shaft 21, the second end of the rotating shaft 21 is slidably connected to the connecting tube 221, for example, a spline connection, and the connecting tube 221 is used to connect to the steering wheel to drive the steering wheel to telescopic movement or rotation. The sleeve 222 is at least partially disposed in the cylinder 1, and the sleeve 222 is slidably connected to the cylinder 1. The sleeve 222 is disposed on the outside of the connecting tube 221, and the sleeve 222 is rotatably connected to the connecting tube 221. The sleeve 222 can extend into the accommodating space 34. Under the action of the moving external force, the steering wheel pushes the connecting tube 221 to slide axially relative to the rotating shaft 21 to move closer to or away from the rotating shaft 21 to perform a telescopic movement. At this time, although the sleeve 222 can rotate relative to the connecting tube 221, in the axial direction, the sleeve 222 moves synchronously with the connecting tube 221, and the sleeve 222 can move into or out of the accommodating space 34, thereby providing sufficient telescopic distance for the telescopic movement of the connecting tube 221 relative to the rotating shaft 21, thereby reducing obstruction during the axial movement adjustment of the steering wheel. Under the action of external rotational force, the steering wheel drives the shaft 21 to rotate relative to the sleeve 222 through the connecting tube 221, and the stator 32 is energized to drive the rotor 31 to rotate. Torque can be applied to the shaft 21 through the jacket 33 to simulate rotational resistance.

[0054] In this embodiment, the outer wall of the sleeve 222 and the inner wall of the cylinder 1 can have the same radial size for easy sliding. The inner diameter of the rotor 31 and the size of the jacket 33 can be larger than the outer diameter of the sleeve 222 to avoid the position of the sleeve 222.

[0055] like Figures 1 to 4As shown, in some embodiments, the end of the cylinder 1 is fixedly connected with a first connecting plate 11 and a second connecting plate 12, and the first connecting plate 11 and the second connecting plate 12 are both arranged in the circumferential direction of the rotating shaft 21, and the first connecting plate 11 and the second connecting plate 12 are both arranged along the axial direction of the rotating shaft 21.

The first connecting plate 11 and the second connecting plate 12 can provide sufficient installation space for the stator 32 and the rotor 31, and avoid affecting the axial layout space of the rotating shaft 21 and the telescopic member 22. The first connecting plate 11 and the second connecting plate 12 are disposed on the outer circumference of the rotating shaft 21 to avoid the position of the telescopic member 22 .

The fourth connecting plate 36 and the rotor 31 can be connected in a surface manner, with a large connection area and a stable connection, thereby improving the bearing capacity of the connection position between the jacket 33 and the rotor 31. In addition, the jacket 33 is rotatably connected to the second connecting plate 12 through the fourth connecting plate 36, and the third connecting plate 35 is surface-connected to the second connecting plate 12, with a large connection area, which can ensure the relative rotation stability between the jacket 33, the third connecting plate 35 and the cylinder 1, and the coaxial centering of the jacket 33 and the rotating shaft 21.

It can withstand radial and axial loads at the same time, runs smoothly, has high transmission efficiency, can ensure high-speed rotation between the sleeve 33 and the cylinder 1, and rotates flexibly to reduce friction.
