[0045] As described in the background art, the steering structure, also known as the steering column, is a component of the vehicle steering system. One end of the steering structure is connected to the steering wheel, and the other end is connected to the steering gear, thereby transmitting the torque of the steering wheel to the steering gear, and then driving the wheels to rotate to achieve vehicle steering.

[0046] A damping structure is usually provided at the end of the steering structure to provide steering assistance to the steering gear and adjust the steering feel of the driver when turning the steering wheel, thereby avoiding the steering feel being too light or too false during steering and ensuring driving stability and safety.

[0047] However, the existing damping structures are usually motors and reduction mechanisms, which occupy a large amount of space and are prone to overlap with the layout areas of other structures, affecting the layout of other structures.

[0048] To solve the above problems, an embodiment of the present application provides an electromagnetic damping steering structure and a vehicle. The electromagnetic damping steering structure includes a first housing, and a first accommodation cavity is formed inside the first housing; a first electromagnet, which is arranged inside the first accommodation cavity; a second electromagnet, which is arranged inside the first accommodation cavity, and the magnetic poles of the second electromagnet are opposite to those of the first electromagnet, and a magnetic field is formed between the first electromagnet and the second electromagnet; a rotating shaft, which is inserted on the first housing, and one end of the rotating shaft is used to be connected to the steering wheel to rotate under the drive of the steering wheel; a rotating member, which is arranged on the rotating shaft, and the rotating member is located between the first electromagnet and the second electromagnet, and the rotating member is configured to cut the magnetic induction lines in the magnetic field under the drive of the rotating shaft, so that the rotating member is subjected to an electromagnetic damping force opposite to its own rotation direction, slowing down the rotation speed of the rotating member, and then feeding back the damping force to the driver through the rotating shaft and the steering wheel, avoiding the steering feel being too light or too fake when steering. At the same time, by adjusting the currents of the first electromagnet and the second electromagnet, the magnitude of the electromagnetic damping force can be adjusted, and thus the steering feel of the driver when turning the steering wheel can be adjusted. Compared with the existing use of a motor and a reduction mechanism as a damper, the electromagnetic damping steering structure provided by the embodiment of the present application occupies less space, avoiding overlapping with the layout areas of other structures, and thus will not affect the layout of other structures on the vehicle.

[0049] The following uses specific embodiments to elaborate in detail on the technical solutions of the embodiments of the present application and how the technical solutions of the embodiments of the present application solve the above technical problems. The following several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following will describe the embodiments of the embodiments of the present application with reference to the drawings.

[0050] Please refer to Figures 1 to 4 . In a first aspect, this embodiment provides an electromagnetic damping steering structure, including a first housing 100, and a first accommodation cavity 110 is formed inside the first housing 100; a first electromagnet 200, which is arranged inside the first accommodation cavity 110; a second electromagnet 300, which is arranged inside the first accommodation cavity 110, and the magnetic poles of the second electromagnet 300 are opposite to those of the first electromagnet 200, and a magnetic field is formed between the first electromagnet 200 and the second electromagnet 300; a rotating shaft 400, which is inserted on the first housing 100, and one end of the rotating shaft 400 is used to be connected to the steering wheel to rotate under the drive of the steering wheel; a rotating member 500, which is arranged on the rotating shaft 400, and the rotating member 500 is located between the first electromagnet 200 and the second electromagnet 300, and the rotating member 500 is configured to cut the magnetic induction lines in the magnetic field under the drive of the rotating shaft 400.

[0051] Specifically, in this embodiment, a first accommodation cavity 110 is formed inside the first housing 100. The first electromagnet 200 and the second electromagnet 300 are oppositely arranged in the first accommodation cavity 110, so that the first housing 100 provides an installation space for the first electromagnet 200 and the second electromagnet 300, and can also ensure that the first electromagnet 200 and the second electromagnet 300 are protected from the external environment.

[0052] It should be noted that in other embodiments, other connection methods may also be adopted between the first electromagnet 200 and the second electromagnet 300 and the first housing 100. This embodiment does not impose any restrictions on this, and can be adaptively selected according to needs.

[0053] Specifically, in this embodiment, the magnetic poles of the first electromagnet 200 and the second electromagnet 300 are opposite, so the magnetic fields between the first electromagnet 200 and the second electromagnet 300 will attract each other, thereby enhancing the magnetic field strength in the space between the first electromagnet 200 and the second electromagnet 300.

[0054] In an alternative embodiment, the magnetic poles of the first electromagnet 200 and the second electromagnet 300 can be made opposite by making the directions of the currents flowing through the first electromagnet 200 and the second electromagnet 300 opposite.

[0055] Since the magnetic poles of the first electromagnet 200 and the second electromagnet 300 are opposite, the first electromagnet 200 and the second electromagnet 300 will attract each other. To prevent the first electromagnet 200 and the second electromagnet 300 from approaching each other under the action of the mutual attraction force, in this embodiment, the first accommodation cavity 110 includes two step grooves arranged at intervals. The first electromagnet 200 and the second electromagnet 300 are respectively arranged in the two step grooves, and an interference fit installation method is adopted to ensure the stability of the installation of the first electromagnet 200 and the second electromagnet 300, thereby preventing the first electromagnet 200 and the second electromagnet 300 from disengaging from the fit under the action of the mutual attraction force.

[0056] In addition, it should be noted that in other embodiments, the installation methods of the first electromagnet 200 and the second electromagnet 300 can also be adaptively selected according to actual needs. This embodiment does not impose any restrictions on this.

[0057] At the same time, the distance between the first electromagnet 200 and the second electromagnet 300 can also be adjusted to ensure that the first electromagnet 200 and the second electromagnet 300 will not disengage from the fit with the accommodation cavity when attracting each other.

[0058] In this embodiment, to ensure the uniformity of the magnetic field, the shapes, sizes, and current intensities of the first electromagnet 200 and the second electromagnet 300 are the same, so that the magnetic field generated between the first electromagnet 200 and the second electromagnet 300 can be relatively uniform.

[0059] Specifically, in this embodiment, the rotating shaft 400 is inserted into the first housing 100. One end of the rotating shaft 400 is connected to the steering wheel to rotate under the drive of the steering wheel. To avoid overlap in the arrangement between the first electromagnet 200 and the second electromagnet 300 and the rotating shaft 400, in this embodiment, both the first electromagnet 200 and the second electromagnet 300 adopt an annular structure, and the rotating shaft 400 passes through the holes in the first electromagnet 200 and the second electromagnet 300 and is inserted into the first housing 100, so as to rotate under the drive of the steering wheel.

[0060] It should be noted that, in some embodiments, the end of the rotating shaft 400 that is not connected to the steering wheel can extend out of the first housing and be connected to the steering gear, so as to transmit the rotational force applied by the driver through the steering wheel to the steering gear and realize the steering of the vehicle.

[0061] Specifically, in this embodiment, a rotating member 500 is provided on the rotating shaft 400. The rotating member 500 is a metal conductor and is located in the magnetic field between the first electromagnet 200 and the second electromagnet 300. The rotating member 500 can rotate under the drive of the rotating shaft 400. Therefore, when the rotating member 500 cuts the magnetic induction line, an induced electromotive force will be generated inside, and then an induced current will be caused. The induced current interacts with the magnetic field between the first electromagnet 200 and the second electromagnet 300 to generate a damping force, which affects the movement of the rotating member 500, that is, a damping force opposite to the rotation direction of the rotating member 500 is generated, slowing down the rotation speed of the rotating member 500, and then feeding back the electromagnetic damping force to the driver through the rotating shaft 400 and the steering wheel, avoiding the feeling of the steering wheel being too light or too fake when the driver controls the steering wheel to turn.

[0062] At the same time, by adjusting the current magnitudes of the first electromagnet 200 and the second electromagnet 300, the magnitude of the electromagnetic damping force can be adjusted, so that the steering feel when the driver turns the steering wheel can be adjusted.

[0063] By adopting the electromagnetic damping steering structure provided in this embodiment, compared with the existing structure that uses a motor and a reduction mechanism as a damper, the electromagnetic damping steering structure provided in this application embodiment occupies less space, avoids overlapping with the layout areas of other structures, and thus will not affect the layout of other structures on the vehicle. At the same time, due to the small volume of the electromagnetic damping steering structure provided in this embodiment, with the development of technology, there is enough area for layout when adding intelligent devices such as a head-up display.

[0064] In an alternative embodiment, the electromagnetic damping steering structure further includes a second housing 600. The rotating shaft 400 is rotatably inserted into the second housing 600. The second housing 600 is located between the first housing 100 and the steering wheel and is used to connect to the instrument panel crossbeam.

[0065] Specifically, in this embodiment, the second housing 600 is used to connect to the instrument panel crossbeam to fix the entire electromagnetic damping steering structure to the instrument panel crossbeam, thereby preventing damage to the electromagnetic damping steering structure caused by vibration and impact during vehicle driving and improving the durability and reliability of the entire electromagnetic damping steering structure.

[0066] Wherein, the rotating shaft 400 is inserted into the second housing 600 and rotates relative to the second housing 600. Thus, by providing the second housing 600, the rotating shaft 400 can be protected to a certain extent, preventing external dust or other impurities from adhering to the rotating shaft 400 and improving the durability of the rotating shaft 400.

[0067] At the same time, by adjusting the shape and size of the second housing 600, the layout of each component within the entire vehicle steering system can be optimized, making the entire steering system more compact.

[0068] In an alternative embodiment, the electromagnetic damping steering structure further includes a bracket 700. The bracket 700 is used to be arranged on the instrument panel crossbeam. An installation hole 720 is provided on the bracket 700, and a first installation groove 610 is provided on the second housing 600. A fastener 710 connects the second housing 600 and the bracket 700 through the installation hole 720 and the first installation groove 610.

[0069] Specifically, the second housing 600 is fixed to the instrument panel crossbeam through the bracket 700 and the fastener 710. Wherein, in this embodiment, the number of the first installation grooves 610 is two, and the two first installation grooves 610 are respectively arranged on both sides of the second housing 600. Correspondingly, the number of the installation holes 720 is two, and the fastener 710 sequentially passes through one installation hole 720, the two first installation grooves 610, and the other installation hole 720, thereby realizing the fixation of both sides of the second housing 600 and ensuring the stability of the connection between the second housing 600 and the instrument panel crossbeam.

[0070] In this embodiment, the number of the fasteners 710 is one. In other embodiments, multiple fasteners 710 can also be provided to further enhance the stability of the connection between the second housing 600 and the instrument panel crossbeam.

[0071] In addition, in this embodiment, the first installation groove 610 is a long groove. When it is necessary to adjust the installation position of the second housing 600, the fastener 710 can be disassembled or loosened, and the second housing 600 is pushed so that the second housing 600 slides relative to the fastener 710 along the length direction of the first installation groove 610, thereby adjusting the installation position of the second housing 600.

[0072] In this embodiment, the fastener 710 is a bolt. By cooperating with a nut, a fastening force is generated, which can prevent relative movement or loosening between the second housing 600 and the bracket 700. At the same time, when disassembly is required, the bolt can also be quickly disassembled.

[0073] In other embodiments, the specific type and specification of the fastener 710 can also be adaptively selected according to actual needs, and this embodiment does not impose any restrictions on this.

[0074] In an alternative embodiment, the rotating shaft 400 includes a first rotating shaft 410 and a second rotating shaft 420 arranged coaxially. The first rotating shaft 410 is used to be connected to the steering wheel, and the rotating member 500 is arranged on the second rotating shaft 420.

[0075] Specifically, in this embodiment, when the driver rotates the steering wheel, the steering wheel drives the first rotating shaft 410 to rotate and transmits the rotational motion to the second rotating shaft 420, thereby driving the rotating member 500 to rotate to cut the magnetic induction lines and generate an electromagnetic damping force.

[0076] In this embodiment, the first rotating shaft 410 and the second rotating shaft 420 can be connected by means of a coupling or a gear to achieve coordinated rotation.

[0077] By providing the connected first rotating shaft 410 and second rotating shaft 420, the forces and torques received by the entire rotating shaft from the road surface can be dispersed to the two rotating shafts, thereby reducing the stress level borne by a single rotating shaft and improving the stability and reliability of the electromagnetic damping steering structure.

[0078] At the same time, by adjusting the connection method and transmission ratio between the first rotating shaft 410 and the second rotating shaft 420, performance parameters such as the response speed and sensitivity of the electromagnetic damping steering structure can be changed.

[0079] In an alternative embodiment, the first rotating shaft 410 is sleeved on the second rotating shaft 420, and the first rotating shaft 410 is configured to slide along the axial direction of the second rotating shaft 420 under the drive of the steering wheel.

[0080] Specifically, in this embodiment, the first rotating shaft 410 is sleeved on the second rotating shaft 420. Pushing the steering wheel can cause the first rotating shaft 410 to slide along the axial direction of the second rotating shaft 420, and then adjust the height of the steering wheel to adapt to the driving habits of different drivers.

[0081] In an alternative embodiment, a limiting groove 411 is formed on the first rotating shaft 410, a limiting member 421 is provided on the second rotating shaft 420, and the limiting member 421 is slidably disposed in the limiting groove 411.

[0082] Specifically, in this embodiment, a limiting groove 411 is formed on the first rotating shaft 410, a limiting member 421 is provided on the second rotating shaft 420, and the limiting member 421 is slidably disposed in the limiting groove 411. When the first rotating shaft 410 slides, the limiting member 421 can slide in the limiting groove 411.

[0083] In an alternative embodiment, the limiting groove 411 extends along the axial direction of the first rotating shaft 410, and the limiting member 421 is correspondingly slidably disposed in the limiting groove 411.

[0084] Specifically, in this embodiment, since the limiting groove 411 is arranged along the axial direction of the first rotating shaft 410, and the first rotating shaft 410 and the second rotating shaft 420 are coaxially arranged, therefore, the limiting groove 411 is arranged along the axial direction of the second rotating shaft 420.

[0085] When the first rotating shaft 410 slides along the axial direction of the second rotating shaft 420, the limiting member 421 can slide in the limiting groove 411 along the axial direction of the first rotating shaft 410, thus not affecting the sliding of the first rotating shaft 410. At the same time, since the limiting member 421 is engaged with the limiting groove 411, the relative position between the first rotating shaft 410 and the second rotating shaft 420 can be restricted, and the relative rotation between the first rotating shaft 410 and the second rotating shaft 420 can be avoided.

[0086] Wherein, the number of the limiting members 421 can be set to be multiple, and the multiple limiting members 421 are evenly and spacedly arranged on the circumferential side of the second rotating shaft 420. Correspondingly, the number of the limiting grooves 411 is multiple, and the limiting members 421 and the limiting grooves 411 are arranged in one-to-one correspondence, so as to improve the connection stability between the first rotating shaft 410 and the second rotating shaft 420.

[0087] In an exemplary embodiment, the limiting member 421 is a spline, the limiting groove 411 is a spline groove, and the key teeth of the spline are engaged with the groove teeth of the spline groove, so as to effectively transmit torque.

[0088] In an alternative embodiment, the electromagnetic damping steering structure further includes a support member 800, the support member 800 is sleeved on the first rotating shaft 410, a second installation groove 620 is formed in the second housing 600, and the support member 800 is disposed in the second installation groove 620.

[0089] Specifically, in this embodiment, the support member 800 is arranged in the second installation groove 620 by an interference fit installation method to ensure the stability of the connection between the support member 800 and the second housing 600.

[0090] Specifically, in this embodiment, the support member 800 is a bearing. The bearing is arranged in the second installation groove 620. The first rotating shaft 410 is inserted into the inner ring of the bearing and fixedly connected to the inner ring of the bearing, so as to ensure the smooth rotation of the first rotating shaft 410, reduce the friction and wear of the first rotating shaft 410 during rotation, and the bearing can also stably support the first rotating shaft 410 to prevent unnecessary displacement or deformation of the first rotating shaft 410. Since the fastener 710 locks the second housing 600 to the bracket 700, and the support member 800 is embedded in the second installation groove 620 and is snap-fitted with the second installation groove 620, the relative position between the first rotating shaft 410 and the second housing 600 can be restricted. At this time, when the driver applies an external force to the steering wheel, the first rotating shaft 410 will not slide axially relative to the second rotating shaft 420, thus avoiding the undesired sliding between the first rotating shaft 410 and the second rotating shaft 420, and ensuring the stability and reliability of the electromagnetic damping steering structure. When it is necessary to adjust the height of the steering wheel, it is necessary to first release the locked state of the fastener 710, that is, unlock the limitation of the relative position between the second housing 600 and the bracket 700. At this time, when the driver presses or pulls the steering wheel, the steering wheel will drive the first rotating shaft 410 to slide axially along the second rotating shaft 420. When the first rotating shaft 410 slides, since the support member 800 is arranged in the second installation groove 620, the second housing 600 can be driven by the support member 800 to slide synchronously with the first rotating shaft 410, so that the second housing 600 slides axially along the second rotating shaft 420 relative to the bracket 700. After the adjustment is completed, the fastener 710 is tightened again, thereby realizing the adjustment of the height of the steering wheel.

[0091] It should be noted that, in this embodiment, a mechanical switch or an electric control button is arranged on the steering wheel. The driver can lock and loosen the fastener 710 by toggling the switch or pressing the button, so as to start adjusting the height of the steering wheel.

[0092] In an alternative embodiment, the first housing 100 has an installation portion 120 for connecting with the instrument panel cross beam.

[0093] Specifically, in this embodiment, the installation portion 120 is a through hole. The fixing member passes through the through hole and is connected to the instrument panel cross beam, thereby fixing the first housing 100 to the instrument panel cross beam, and further ensuring the stability of the connection between the entire electromagnetic damping steering structure and the instrument panel cross beam.

[0094] Meanwhile, since the installation part 120 is a through hole, before being locked by a fixing member, the installation part 120 can rotate relative to the fixing member, so that the installation position of the entire electromagnetic damping steering structure can be adjusted adaptively and then fixed.

[0095] Among them, the installation part 120 can also be a buckle, a claw or other structures that can achieve connection, and this embodiment does not impose any restrictions on this.

[0096] By connecting the first housing 100 and the second housing 600 to the instrument panel crossbeam respectively, a stable triangular support structure is formed, so that the forces and torques from different directions can be effectively dispersed and resisted, and the stability and rigidity of the entire electromagnetic damping packaging structure are improved.

[0097] In an alternative embodiment, the electromagnetic damping steering structure further includes a control member 900, and both the first electromagnet 200 and the second electromagnet 300 are electrically connected to the control member 900.

[0098] Specifically, in this embodiment, the electromagnetic damping steering structure further includes a control member 900, and both the first electromagnet 200 and the second electromagnet 300 are electrically connected to the control member 900, so that the magnitude of the current in the first electromagnet 200 and the second electromagnet 300 can be controlled through the control member 900, and then the adjustment of the electromagnetic damping force is realized.

[0099] In an alternative embodiment, the control member 900 is disposed in the first accommodation cavity 110.

[0100] In an alternative embodiment, the steering angle of the steering wheel can be detected to obtain the steering direction and amplitude of the driver, so as to calculate the driving intention of the driver, and the electromagnetic damping force can be adjusted to a suitable value through the control member.

[0101] In a second aspect, this embodiment further provides a vehicle, including a vehicle body, a steering wheel and the electromagnetic damping steering structure according to any item in the first aspect, and the steering wheel is connected to the vehicle body through the electromagnetic damping steering structure.

[0102] Among them, the specific structure of the electromagnetic damping steering structure has been described in the above embodiments and will not be elaborated here.

[0103] The vehicle provided in this embodiment includes a vehicle body, a steering wheel, and the electromagnetic damping steering structure according to any one of the first aspects. The steering wheel is connected to the vehicle body through the electromagnetic damping steering structure. Among them, the electromagnetic damping steering structure includes a first housing 100, and a first accommodating cavity 110 is formed inside the first housing 100; a first electromagnet 200, which is arranged inside the first accommodating cavity 110; a second electromagnet 300, which is arranged inside the first accommodating cavity 110, and the magnetic poles of the second electromagnet 300 are opposite to those of the first electromagnet 200, and a magnetic field is formed between the first electromagnet 200 and the second electromagnet 300; a rotating shaft 400, which is inserted on the first housing 100, and one end of the rotating shaft 400 is used to be connected to the steering wheel to rotate under the drive of the steering wheel; a rotating member 500, which is arranged on the rotating shaft 400, and the rotating member 500 is located between the first electromagnet 200 and the second electromagnet 300. The rotating member 500 is configured to cut the magnetic induction lines in the magnetic field under the drive of the rotating shaft 400, so that the rotating member 500 is subjected to an electromagnetic damping force opposite to its own rotation direction, slowing down the rotation speed of the rotating member 500, and then feeding back the damping force to the driver through the rotating shaft 400 and the steering wheel, avoiding too light or false feeling during steering. At the same time, by adjusting the currents of the first electromagnet 200 and the second electromagnet 300, the magnitude of the electromagnetic damping force can be adjusted, and further the steering feel of the driver when turning the steering wheel can be adjusted. Compared with the existing use of motors and reduction mechanisms as dampers, the electromagnetic damping steering structure provided in this embodiment occupies less space, avoids overlapping with the layout areas of other structures, and thus will not affect the layout of other structures on the vehicle.
