[0046] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0047] In the present disclosure, unless otherwise specified, "inside" and "outside" refer to the inside and outside of the contour of the corresponding component. Furthermore, the terms "first" and "second" used in the present disclosure are to distinguish one element from another and have no order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0048] according to Figures 1 to 4 As shown, the first aspect of the present disclosure provides a decoupling coupling device, which includes a first column housing 10, a coupling member 5, a decoupling member 4, a clutch member 20 and a driving mechanism 3. The coupling member 5 is used to connect with the steering gear, for example, it can be connected to the universal joint of the steering gear, and the decoupling member 4 is used to connect with the hand feeling module; the clutch member 20 is movably arranged in the first column housing 10 and is used to be connected to the steering wheel through the core shaft of the steering column 1. The clutch member 20 has a first engaging portion 21 and a second engaging portion 22. The first engaging portion 21 is docked with the coupling member 5 at the coupling position of the clutch member 20 to transmit the power of the steering wheel to the steering gear, so that the driver can The driving mode or EPS steering mode is entered according to the actual situation; the second engaging portion 22 is docked with the decoupling member 4 at the decoupling position of the clutch 20 to transmit the resistance of the hand feeling module to the steering wheel, so that the driver can enter the wire control mode or the game mode according to the actual situation. The driver can obtain the same or similar driving feeling when operating the steering wheel when the clutch 20 is in the coupling position through the damping transmitted to the steering wheel by the hand feeling module; the driving mechanism 3 includes a driving component and a connecting member 34, the driving component is located outside the steering column 1, and the driving component drives the clutch 20 to move between the coupling position and the decoupling position through the connecting member 34 that penetrates the first column housing 10.

[0049] Through the above technical solution, the clutch 20 is arranged in the first column housing 10, which can avoid occupying the assembly space outside the steering column 1, is convenient for assembly, and has low space utilization. The clutch 20 has a first joint 21 for docking with the coupling member 5 and a second joint 22 for docking with the decoupling member 4. It has a high degree of integration, is convenient for processing and manufacturing, and reduces the occupied space. The drive assembly is located outside the steering column 1 and drives the clutch 20 to move through the connecting member 34 that penetrates the first column housing 10, which is convenient for assembly and maintenance.

[0050] In addition, the driving assembly located outside the steering column 1 drives the clutch 20 located inside the steering column 1 to move between the coupling position and the decoupling position to achieve switching between the decoupling and coupling states, so that the driver can choose to enter different driving modes, thereby enhancing the operability and fun of the vehicle.

[0051] In some possible implementations, for example, referring to Figure 4As shown, the structures of the first joint portion 21 and the second joint portion 22 can be the same, which can save processing steps and shorten processing time during the process. It is understandable that the structures of the first joint portion 21 and the second joint portion 22 can also be different, and this disclosure does not make specific limitations on this. Those skilled in the art can make adaptive adjustments according to actual conditions.

[0052] Optionally, the clutch 20 can be a plane symmetrical structure. For example, the first engaging portion 21 and the second engaging portion 22 can be coaxially arranged. The first engaging portion 21 and the second engaging portion 22 can be symmetrically arranged about a plane perpendicular to the axial direction of the clutch 20, and the plane passes through the circumferential center position of the clutch 20. This can further facilitate processing and manufacturing and reduce development costs and manufacturing costs.

[0053] In some possible implementations, for example, referring to Figure 4 As shown, the clutch 20 may include a cylinder, which is used to be sleeved on the core shaft. For example, the cylinder can be constructed as a hollow cylinder, and the core shaft can be inserted into the cylinder. The cylinder can move along the axial direction of the core shaft, and the cylinder is circumferentially limited relative to the core shaft so that the core shaft and the cylinder can rotate synchronously. For example, a spline structure can be provided inside the cylinder so that the cylinder and the core shaft are spline-matched to achieve the cylinder being able to rotate synchronously with the core shaft and being able to move axially relative to the core shaft.

[0054] In some practicable embodiments, for example, with reference to FIG. 4 , the cylinder has a first end A and a second end B that are opposite to each other in the axial direction, the first end A has a first annular reinforcement portion 211 and a plurality of first teeth 212 that are arranged at intervals along the circumference of the outer wall of the first annular reinforcement portion 211 and extend in the axial direction, the plurality of first teeth 212 forming a first engagement portion 21, and the second end B has a second annular reinforcement portion 221 and a plurality of second teeth 222 that are arranged at intervals along the circumference of the outer wall of the second annular reinforcement portion 221 and extend in the axial direction, the plurality of second teeth 222 forming a second engagement portion 22. The first teeth 212 and the second teeth 222 are respectively provided on the first annular reinforcement portion 211 and the second annular reinforcement portion 221, and the meshing strength of the teeth can be enhanced by the annular reinforcement portion, so that the fit between the clutch 20 and the decoupling member 4 and the coupling member 5 is more reliable. Of course, the first joining portion 21 and the second joining portion 22 can be implemented with any other suitable structure not shown in the figure. For example, the first annular reinforcement portion 211 and the second annular reinforcement portion 221 can be eliminated, while the first tooth portion 212 and the second tooth portion 222 are retained. Alternatively, the first joining portion 21 and the second joining portion 22 can also be constructed as a spline structure, or the first joining portion 21 and the second joining portion 22 can be constructed as a cross protrusion or a cross groove. The present disclosure does not make specific limitations on this, and those skilled in the art can make adaptive adjustments based on actual conditions.

[0055] In some possible implementations, for example, referring to Figure 3 to Figure 4 As shown, the first engagement portion 21 may include a plurality of first teeth 212 arranged at intervals along the circumferential direction, and the coupling member 5 may include a first sleeve portion 52 and a plurality of third teeth arranged at intervals along the circumferential direction on the inner wall of the first sleeve portion 52, and the plurality of first teeth 212 and the plurality of third teeth may mesh with each other at the coupling position. By providing the first teeth 212 and the third teeth, the reliability and stability of the clutch member 20 when mating with the coupling member 5 may be enhanced. Among them, an end shaft 51 is provided at one end of the first sleeve portion 52 away from the first column housing 10, and the end shaft 51 is used to connect with the universal joint. When the first tooth portion 212 of the first engaging portion 21 of the clutch 20 and the third tooth portion of the first sleeve portion 52 of the coupling 5 are engaged with each other, the torque transmitted from the steering wheel can be transmitted from the core shaft and the clutch 20 to the universal joint connected to the end shaft 51, so that the steering gear outputs power from the wheel under the control of the steering torque of the steering wheel, and the wheel deflects in the corresponding direction, so that the driver can obtain an actual road driving feel; optionally, in the coupled state, the vehicle can enter EPS steering mode or driving mode.

[0056] It is understandable that the second engagement portion 22 may also include a plurality of second teeth 222 spaced apart in the circumferential direction, the decoupling member 4 includes a second sleeve portion 42 and a plurality of fourth teeth disposed on the inner wall of the second sleeve portion 42 and spaced apart in the circumferential direction, and the plurality of second teeth 222 and the plurality of fourth teeth can mesh with each other in the decoupling position. When the second teeth 222 of the second engagement portion 22 of the clutch member 20 mesh with the fourth teeth of the second sleeve portion 42 of the decoupling member 4, the torque transmitted from the steering wheel cannot be transmitted to the steering gear, the steering column 1 is disconnected from the steering gear so that the rotation of the steering wheel does not drive the deflection of the wheels, and at this time the torque feedback of the steering wheel is provided by the decoupling member 4; optionally, in the decoupling state, the vehicle can enter a control-by-wire mode or a game mode.

[0057] It should be noted that the hand feeling module may include a second motor 44 and a transmission member 41. The second motor 44 may drive the decoupling member 4 to rotate through the transmission member 41. For example, the transmission member 41 may include a worm 411. The decoupling member 4 may include a worm wheel 43 connected to the second sleeve portion 42. The worm wheel 43 is located on the side of the second sleeve portion 42 away from the clutch 20. The worm wheel 43 and the worm 411 are connected in transmission. The second motor 44 can drive the worm 411 to drive the worm wheel 43 to rotate. Among them, the worm wheel 43 and the second sleeve portion 42 can be constructed as a whole for easy assembly. In addition, the transmission member 41 may also be a gear, and the second sleeve portion 42 is correspondingly provided with a tooth portion that meshes with the gear. This disclosure does not specifically limit this.

[0058] In some possible implementations, for example, referring to Figure 3 and Figure 4 As shown, the clutch 20 may be sleeved with a bearing 23, an inner sleeve 24 and an outer sleeve 25 in sequence radially outward, the outer sleeve 25 is limited to the inner wall of the first column housing 10 along the axial direction and along the circumferential direction, the clutch 20, the bearing 23 and the inner sleeve 24 can move synchronously relative to the outer sleeve 25 along the axial direction, the clutch 20 can rotate relative to the inner sleeve 24 around its own central axis through the bearing 23, the outer sleeve 25 is provided with an axially extending avoidance opening 251, and the connecting member 34 passes through the avoidance opening 251 and is connected to the inner sleeve 24. The provision of the outer sleeve 25 can prevent the inner sleeve 24 from directly contacting the inner wall surface of the first column housing 10, and during the processing process, it is not necessary to perform specific processing on the inner wall surface of the first column housing 10, reducing the processing process, and realizing the movement of the clutch 20 through the outer sleeve 25, simplifying the structure, and having more reliability and stability. In order to prevent the clutch 20 from axially moving relative to the bearing 23 , a retaining spring may be provided to limit the bearing 23 in the axial direction. The retaining spring may be located on opposite sides of the bearing 23 in the axial direction.

[0059] In order to facilitate the cooperation between the inner sleeve 24 and the outer sleeve 25, the stability between the inner sleeve 24 and the outer sleeve 25 is enhanced. In some practicable embodiments, for example, referring to Figure 3 As shown, the inner wall surface of the outer sleeve 25 can be provided with a plurality of strip protrusions 252 arranged at intervals in the circumferential direction and extending in the axial direction, and the outer wall surface of the inner sleeve 24 can be provided with a guide groove that slides axially with the strip protrusions 252. The strip protrusions 252 are plugged into the guide grooves to provide greater stability between the inner sleeve 24 and the outer sleeve 25. Alternatively, the outer wall surface of the inner sleeve 24 can also be a smooth surface, which slides and fits against the strip protrusions 252. The provision of the smooth surface can reduce the contact area between the inner sleeve 24 and the outer sleeve 25, thereby reducing the friction between the two, and making the movement of the inner sleeve 24 relative to the outer sleeve 25 smoother.

[0060] The structural limitation of the inner sleeve 24 and the outer sleeve 25 in the present disclosure is only for the present disclosure, and the structures of the inner sleeve 24 and the outer sleeve 25 can be adaptively adjusted according to the actual needs, for example, the outer wall surface of the inner sleeve 24 can be configured as a strip protrusion 252, and the inner wall surface of the outer sleeve 25 can be configured as a guide groove. The present disclosure does not make specific limitations on this, as long as the movement of the inner sleeve 24 relative to the outer sleeve 25 can be achieved.

[0061] In some practicable embodiments, a guide positioning structure may be provided between the outer sleeve 25 and the first column housing 10, and the guide positioning structure includes a guide protrusion and a guide groove that are slidably matched, one of which is provided on the outer wall surface of the outer sleeve 25, and the other is provided on the inner wall surface of the first column housing 10. The provision of the guide positioning structure can make the assembly between the first column housing 10 and the outer sleeve 25 more convenient and rapid. It can be understood that, in order to prevent the outer sleeve 25 from moving relative to the first column housing 10, a fixing member that passes through the first column housing 10 may be provided on the outside of the first column housing 10, and a matching member that cooperates with the fixing member may be provided on the outer wall surface of the outer sleeve 25, for example, the fixing member may be a screw, and the matching member may be a threaded hole, so that the outer sleeve 25 can be further fixed when it is assembled into the inside of the first column housing 10.

[0062] In some possible implementations, for example, referring to Figure 1 and Figure 2 As shown, the driving assembly may include a first motor 31, a lead screw 33 and a nut 32. The first motor 31 is arranged on the first column housing 10. The lead screw 33 is rotatably arranged on the first column housing 10 around its own axis and is drivingly connected to the first motor 31. For example, a mounting portion 12 may be formed on the first column housing 10. The mounting portion may include a first mounting portion 121 and a second mounting portion 122. The two ends of the lead screw 33 are respectively mounted in the mounting holes of the first mounting portion 121 and the second mounting portion 122. The nut 32 is threadedly connected to the lead screw 33 and connected to the clutch 20 through a connecting member 34. When working, the first motor 31 drives the lead screw 33 to rotate to drive the nut 32 to move along the axial direction of the lead screw 33. In this way, the clutch 20 connected to the nut 32 through the connecting member 34 moves in the first column housing 10 under the movement of the nut 32 to achieve docking with the decoupling member 4 or the coupling member 5. In this way, the transmission efficiency is better, the clutch member 20 can be moved to the coupling position or the decoupling position more accurately, and the transmission process is more stable.

[0063] Among them, the outer wall of the first column housing 10 may be provided with a guide hole 13 for the connection member 34 to pass through, and the two ends of the connection member 34 are respectively connected to the nut 32 and the clutch 20. It can be understood that the two ends of the connection member 34 can be directly or indirectly connected to the nut 32 and the clutch 20. Exemplarily, the connection member 34 may include at least two connecting rods, and the at least two connecting rods are respectively connected to the nut 32 and the clutch 20. For example, a connecting hole 241 can be opened on the inner sleeve 24, and the connecting rod is connected to the connecting hole 241. At least two connecting rods are respectively located on both sides of the lead screw 33. For example, the two connecting rods can be arranged symmetrically so that when the connecting rod drives the clutch 20 to move, the clutch 20 is subjected to more uniform force and moves more quickly. Of course, in order to better tighten the connecting rod and the connecting hole 241 to prevent the two from being separated, the connecting rod can also include a threaded rod section, which is arranged at one end of the connecting rod close to the inner sleeve 24, and the nut is fixedly inserted into the threaded rod section of the connecting hole 241 from the side of the inner sleeve 24 away from the connecting rod. It is understandable that the connection hole 241 and the connection rod may also be fixed by a shape fit, for example, the inner wall surface of the connection hole 241 may be provided with a plurality of protrusions, and the connection rod may be provided with a groove. In addition, the connection member 34 may also include a connection plate connected to the nut 32, and the connection rod passes through the connection plate and is connected to the clutch member 20 or the inner sleeve 24. The present disclosure is not limited thereto.

[0064] Optionally, the driving assembly may also include any one of a linear motor, a cylinder, a hydraulic cylinder, and an electric push rod, and those skilled in the art may select one according to actual needs.

[0065] According to a second aspect of the present disclosure, a steering column 1 is provided, comprising a decoupling coupling device, a second column housing and a core shaft. The decoupling coupling device has all the beneficial effects of the above-mentioned specific embodiments. The decoupling component 4 is located at the end of the first column housing 10 that is connected to the second column housing. The core shaft passes through the decoupling component 4 from the second column housing and extends to the inside of the first column housing 10 to be connected to the clutch 20. The core shaft is used to be connected to the steering wheel to transmit torque.
