Detailed Description
The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
Referring to fig. 1, 2, 3, and 4 and 5, the present invention provides a steering column including a first column 2, a first mandrel 3 rotatably disposed within the first column (e.g., the first mandrel 3 may be rotatably disposed within the first column 2 via a bushing or bearing), a second column 4, and a second mandrel 5 rotatably disposed within the second column 4 (e.g., the second mandrel 5 may be rotatably disposed within the second column 4 via a bushing or bearing), wherein the first column 2 is axially movable to switch between a coupled position and a decoupled position; wherein, in the coupled position, the first mandrel 3 and the second mandrel 5 are connected to be capable of synchronous rotation; in the uncoupled position, the torque transmission between the first spindle 3 and the second spindle 5 is disconnected, for example in the uncoupled position the first spindle 3 cannot bring about a synchronous rotation of the second spindle 5.
Since the first mandrel 3 is rotatably arranged within the first tubular string 2, the first mandrel 3 and the first tubular string 2 will be able to move axially together, such that in the coupled position the first mandrel 3 and the second mandrel 5 are connected to be able to rotate in synchronism to transmit the torque of the steering wheel; in the decoupled position, the torque transmission between the first spindle 3 and the second spindle 5 is disconnected, and the steering torque provided by the steering wheel cannot be transmitted through the first spindle and the second spindle, for example, the steering wheel will drive the first spindle 3 to rotate and cannot drive the second spindle 5 to rotate. In this way, the coupling and decoupling of the first mandrel 3 and the second mandrel 5 of the steering column can be conveniently realized, so as to realize the on-off of steering torque transmission of the steering wheel. In addition, in the decoupling position, the steering column can be provided with a game function, so that in the decoupling position, after one of the first mandrel and the second mandrel, which can also receive the steering torque of the steering wheel, is connected with the hand feeling simulation unit, when one of the first mandrel and the second mandrel, which can also receive the steering torque of the steering wheel, rotates, the hand feeling simulation unit provides damping to provide steering simulation hand feeling, and therefore a user can feel the same or similar operation feeling as the steering wheel is operated in the coupling position through the steering wheel, and can rotate the steering wheel through a game picture displayed by the vehicle-mounted display screen to play racing games or other games, and tire abrasion caused by repeated rotation of the steering wheel when the vehicle stops is avoided.
The first mandrel 3 may be rotatably disposed in the first tubular string 2 via a rotating sleeve or bearing, and similarly the second mandrel 5 may be rotatably disposed in the second tubular string 4 via a rotating sleeve or bearing.
In addition, in order to be able to lift the application range of the steering column to meet different height use demands of users, the first column 2 is axially moved to be able to adjust the axial length of the steering column to a plurality of desired positions. For example, a user can drive the first pipe column 2 to move upwards to a required position axially through the driving device 1, and then the first mandrel 3 and the second mandrel 5 are connected to be capable of synchronously rotating, so that the use requirements of different axial heights are met.
In addition, at each desired position, i.e. when the first pipe string 2 is axially moved to any desired position such that the steering wheel meets the desired height, the first pipe string 2 is axially movable to switch between the coupled and uncoupled positions. That is, in each desired position, the first tubular string 2 may be driven axially by the driving device 1 to switch between a coupled position, in which the first mandrel 3 and the second mandrel 5 are rotated synchronously, and a uncoupled position, in which the first mandrel 3 is rotated without providing a simulated hand to the first mandrel, for example, by the hand simulation unit, and in which the second mandrel 5 is not rotated by the rotation of the first mandrel 3, for example, in one embodiment, while the hand simulation unit, described below, provides damping to the first mandrel to provide a simulated hand when the first mandrel 3 is rotated.
In addition, in the steering column, the first spindle 3 and the second spindle 5 may be provided in a non-nested arrangement, for example, a lower engagement fluted disc is provided at a lower end of the first spindle 3, and an upper engagement fluted disc is provided at an upper end of the second spindle 5, so that, in the coupled position, the lower engagement fluted disc on the first spindle 3 and the upper engagement fluted disc on the second spindle 5 are engaged and connected to be capable of synchronous rotation, and, in the decoupled position, the lower engagement fluted disc on the first spindle 3 and the upper engagement fluted disc on the second spindle 5 are axially disengaged, so that torque transmission therebetween is disconnected.
Alternatively, referring to fig. 2, 3 and 4, the first spindle 3 and the second spindle 5 may be arranged in a nested arrangement, such that, in the decoupled position, the first spindle 3 and the second spindle 5 are arranged in a nested arrangement, such a nested arrangement of the first spindle 3 and the second spindle 5 may enable one of the first spindle 3 and the second spindle 5 to form an axial guiding tube for the other, such that a good guiding effect can be achieved when moving axially, while such a nested arrangement may also play a role in reinforcing the strength of the steering column itself.
Of course, the first mandrel 3 may be inserted into the second mandrel 5, or the second mandrel 5 may be inserted into the first mandrel 3.
In addition, when the first mandrel 3 and the second mandrel 5 are sleeved, one of the first mandrel 3 and the second mandrel 5 can be provided with a groove and an annular groove which are axially arranged at intervals, the axial grooves between the groove and the annular groove are communicated, one of the first mandrel 3 and the second mandrel 5 can be provided with an elastic arm, the front end of the elastic arm is provided with a clamping hook, the clamping hook can enter the groove and can be moved out of the groove under the driving of the driving device 1, in this way, in a coupling position, the clamping hook can be clamped into the groove to enable the first mandrel 3 and the second mandrel 5 to synchronously rotate, in a decoupling position, the clamping hook enters the annular groove through the axial grooves, in this way, when the first mandrel 3 rotates, the clamping hook moves along the annular groove, and at this moment, the first mandrel 3 does not drive the second mandrel 5 to rotate when rotating.
Of course, the grooves and the annular grooves may be respectively arranged in a plurality of axially alternating intervals and sequentially communicated through the axial grooves, so that under the driving of the driving device 1, the hooks can enter into the grooves and the annular grooves, and the driving device 1 can drive the first pipe column 2 to axially move so as to adjust the axial length of the steering pipe column to a plurality of required positions, and at each required position, the driving device 1 can drive the first pipe column 2 to axially move so as to switch between the coupling position and the decoupling position.
In addition, when the first mandrel 3 and the second mandrel 5 are sleeved, referring to fig. 3 and 4, the first mandrel 3 includes a first tooth groove section 6, and the second mandrel 5 includes a second tooth groove section 7, where, under the driving of the driving device 1, in the coupling position, the first tooth groove section 6 and the second tooth groove section 7 are engaged, so that the first mandrel 3 and the second mandrel 5 can synchronously rotate, and in the decoupling position, the first tooth groove section 6 and the second tooth groove section 7 are axially staggered to be separated, so that the second mandrel 5 cannot be driven to rotate when the first mandrel 3 rotates. The first tooth slot section 6 and the second tooth slot section 7 can be a section extending in the circumferential direction, or can be ring teeth arranged in the whole circumference.
Further, as shown in fig. 3 and 4, the first spline sections 6 are plural and axially spaced so that a first toothless section 14 will be formed between adjacent first spline sections 6, the second spline sections 7 are plural and axially spaced so that a second toothless section 15 will be formed between adjacent second spline sections 7, wherein, in the coupled position, one first spline section 6 and one second spline section 7 mesh to form a spline mesh group, the spline mesh group being plural; in the decoupling position, the plurality of tooth socket engagement sets are axially staggered and disengaged, that is, the first tooth socket segment 6 will enter the second toothless segment 15, and the second tooth socket segment 7 will enter the first toothless segment 14, and the first mandrel 3 will not drive the second mandrel 5 to rotate when rotating. In the coupling position, the stability of power transmission between the first mandrel 3 and the second mandrel 5 can be effectively improved through a plurality of tooth groove meshing groups. In addition, under the drive of the drive device 1, the first spline section 6 and the second spline section 7 are engaged to form a plurality of spline engagement groups, and the spline section 6 can enter the second toothless section 15, and the second spline section 7 can enter the first toothless section 14, so that the drive device 1 can drive the first column 2 to move axially to adjust the axial length of the steering column to a plurality of required positions, and at each required position, the drive device 1 can drive the first column 2 to move axially to switch between the coupled position and the uncoupled position.
In addition, the number of first spline sections 6 and second spline sections 7 may be the same or different, for example, in the embodiment shown in fig. 3 and 4, the number of first spline sections 6 is greater than the number of second spline sections 7. Thus, in the coupled position, the number of spline engagement sets is the number of second spline sections 7.
In addition, the first cogged section 6, the first toothless section 14, the second cogged section 7 and the second toothless section 15 may have any suitable axial distance, e.g. may have any suitable identical axial distance, such as may be 8-15mm, preferably 10mm.
In addition, as described above, the first mandrel 3 may be inserted into the second mandrel 5, or the second mandrel 5 may be inserted into the first mandrel 3. For example, in the embodiment shown in fig. 3 and 4, the first mandrel 3 is a hollow pipe section, a plurality of axially spaced first spline sections 6 are formed on the inner peripheral surface of the hollow pipe section, the second mandrel 5 is inserted into the hollow pipe section, a plurality of axially spaced second spline sections 7 are formed on the outer peripheral surface of the second mandrel 5, and the number of the second spline sections 7 is smaller than the number of the first spline sections 6. Since the first mandrel 3 is a hollow pipe section, the weight of the first pipe string 2 can be effectively reduced so that the driving device 1 can more easily drive the first pipe string 2 to move axially.
In addition, referring to fig. 5, the first tubular string 2 includes a casing section 8 and a guide tube section 10 fixedly fitted over the casing section 8 by a support sleeve 9, the guide tube section 10 being axially movably inserted in the second tubular string 4, the guide tube section 10 being for connection with the driving device 1, for example, the driving device 1 being capable of driving the guide tube section 10 to axially move. In this way, the guide pipe section 10 can correspondingly enlarge the outer diameter of the first pipe string 2, so that the radial fit gap between the first pipe string 2 and the second pipe string 4 is reduced, and thus, for example, when the driving device 1 can drive the guide pipe section 10 to move axially, the reduced fit gap can play a role in guiding and positioning the movement of the first pipe string 2, so that the axial movement of the first pipe string 2 is smoother.
In addition, the driving device 1 may be connected to a portion of the guide pipe section 10 that leaks from the second pipe string 4, for example, the driving device 1 may be an oil cylinder or an air cylinder, and a piston rod of the oil cylinder or the air cylinder is connected to a portion of the guide pipe section 10 that leaks from the second pipe string 4, so that the oil cylinder or the air cylinder can drive the first pipe string 2 to move axially.
Alternatively, an axial guide hole is formed on the side wall of the second pipe column 4, a guide slide block 11 extending radially from the axial guide hole is arranged on the guide pipe section 10, and the guide slide block 11 can axially guide and slide in the axial guide hole; the guide slide 11 is slidably arranged on a slide rail 12, the guide slide 11 being intended for connection with the drive device 1. For example, the drive device 1 can drive the guide slide 11 to slide on the slide rail 12. In this way, the pilot segment 10 can be fully or substantially fully received within the second tubular string 4 (a small portion of the pilot segment 10 leaks out of the second tubular string 4), thereby reducing the axial length of the steering tubular string. In addition, by the axial guiding action between the guide slider 11 and the axial guide hole, and the axial guiding action of the slide rail 12 to the guide slider 11, and the axial guiding action of the second pipe string 4 to the guide pipe section 10, the stability and reliability of the axial movement of the first pipe string 2 relative to the second pipe string 4 can be significantly improved under these three axial guiding actions. For example, the first and second spline sections 6 and 7 can be made to move axially more accurately and smoothly to engage or disengage.
In addition, the steering column comprises a drive device 1, which drive device 1 is arranged on the second column 4 and is capable of driving the first column 2 to move axially for switching between the coupled position and the uncoupled position. Thus, with the drive device 1, the drive device 1 can be controlled by the control unit of the vehicle, so that the drive device 1 can be controlled by the control unit when decoupling is required by the user.
In addition, the driving device 1 may be a motor, the sliding rail 12 may be a screw, the guide slider 11 is formed with a screw hole, and the screw is matched in the screw hole, so that when the motor drives the screw to rotate, the guide slider 11 will axially move. Or, the guide slide block 11 is formed with a rack, and the driving gear of the motor is meshed with the rack, so that when the motor drives the driving gear to rotate, the rack can be driven to axially move so as to drive the guide slide block 11 to axially move. In addition, the driving device 1 may be a cylinder or a hydraulic cylinder, and a piston rod of the cylinder or the hydraulic cylinder is directly connected with the guide slide 11 to drive the guide slide 11 to axially move. Of course, the drive device 1 may also be of other types, for example, an electromagnet or the like.
In addition, in the steering column, the first mandrel 3 and the second mandrel 5 may be used according to the application, for example, in one embodiment, the first column 2 is an upper column, the first mandrel 3 is an upper column, the second column 4 is a lower column, and the second mandrel 5 is a lower column. Alternatively, in another embodiment, the first pipe column 2 is an upper pipe column, the first mandrel 3 is an upper mandrel, the second pipe column 4 is a middle pipe column, and the second mandrel 5 is a middle mandrel. Alternatively, in another embodiment, the first pipe column 2 is a middle pipe column, the first mandrel 3 is a middle mandrel, the second pipe column 4 is a lower pipe column, and the second mandrel 5 is a lower mandrel.
Further, referring to fig. 1, the steering column further includes a feel simulation unit 13; in the decoupled position, one of the first spindle 3 and the second spindle 5, which is also capable of continuing to receive the steering torque of the steering wheel, is combined with the spindle as a feel simulation unit; for example, the feel simulation unit 13 and the feel simulation unit are coupled in power transfer connection with the spindle, and in the decoupled position, the feel simulation unit 13 is capable of providing damping to the feel simulation unit in combination with the spindle to provide a steering simulation feel when the feel simulation unit is rotated in combination with the spindle.
For example, in one embodiment, referring to fig. 1 and 5, a feel simulation unit 13 is provided on the first tubular string 2 and in power transmission connection with the first mandrel 3, wherein in the coupled position the feel simulation unit 13 does not provide a simulated feel to the first mandrel 3, and in the decoupled position the feel simulation unit 13 provides a simulated feel to the first mandrel 3 when the first mandrel 3 is rotated. Therefore, the coupling and decoupling of the first mandrel and the second mandrel of the steering column are conveniently realized, and meanwhile, the steering column can have a game function.
The hand feeling simulation unit 13 may be a hand feeling simulation motor, for example, in the coupling position, the control unit of the vehicle controls the hand feeling simulation motor not to be started, so that the hand feeling simulation motor is not started when the first spindle 3 and the second spindle 5 are rotated synchronously, and at this time, the hand feeling simulation unit 13 does not provide the first spindle 3 with a simulated hand feeling. In the uncoupled position, when the user needs to play, the control unit of the vehicle controls the hand feel simulation motor to start, so that the hand feel simulation motor provides a simulated hand feel to the first pipe column 2 when the first mandrel 3 rotates.
The hand feeling simulation unit 13 may include a torsion bar shaft rotatably disposed on the pipe column, and a power transmission connection is provided between the torsion bar shaft and the first mandrel 3, wherein in the coupling position, the first mandrel 3 rotates to drive the torsion bar shaft to idle, and the torsion bar shaft does not provide damping to the first mandrel 3; in the decoupled position, the torsion bar shaft can twist under the drive of the first spindle 3 when the first spindle 3 rotates to provide damping to the first spindle 3 to provide steering feel. Of course, the torsion bar shaft can be twisted to a desired extent and returned under the action of the rotational force, for example, the torsion bar shaft may be an elastic shaft, or the torsion bar shaft may include a shaft body and an elastic member such as a rubber cylinder or torsion spring fitted over the shaft body.
Of course, the feel simulation unit 13 may be of other types as long as in the decoupled position, the feel simulation unit in combination with the spindle can provide damping to the feel simulation unit in combination with the spindle to provide a steering simulation feel when the spindle is rotated under the rotation of the steering wheel.
Finally, the present application provides a vehicle provided with a steering column as any of the above. In this way, as described above, the entertainment and overall quality of the vehicle is effectively improved.
