[0037] Reference is made below to Figures 1-7 describe a steering column assembly 100 according to an embodiment of the present invention.

[0038] As Figures 1 to 7 shown, the steering column assembly 100 according to an embodiment of the present invention includes: a steering column housing 1, a steering column tube 2, an upper steering column spindle 3, a lower steering column spindle 4, and a first drive assembly 5; the steering column assembly 100 is mainly used for a vehicle, wherein the vehicle includes: wheels, a transmission assembly, a steering wheel 13, and the steering column assembly 100, the transmission assembly is connected between the steering column assembly 100 and the wheels, and the steering wheel 13 is mounted at the upper end of the steering column assembly 100 to control the steering of the wheels through the steering column assembly 100 and the transmission assembly.

[0039] Furthermore, the steering column housing is rotatably mounted on the vehicle body; the steering column tube 2 is mounted in the steering column housing 1 and is adapted to reciprocate axially; the steering column housing can be used to protect the internal steering column tube 2 from external damage, and in addition, the steering column housing can also provide an installation space for other components; the upper steering column spindle 3 is rotatably mounted in the steering column tube 2, and the upper end of the upper steering column spindle 3 is detachably connected to the steering wheel 13; the upper end of the lower steering column spindle 4 is drivingly connected to the lower end of the upper steering column spindle 3, and the lower end of the lower steering column spindle 4 is drivingly connected to the transmission assembly; when the steering wheel 13 is rotated, the steering wheel 13 can drive the upper steering column spindle 3 to rotate, and at the same time, the upper steering column spindle 3 drives the lower steering column spindle 4 to rotate through a driving connection, and then the lower steering column spindle 4 drives the transmission assembly and controls the direction of the wheels through the transmission assembly.

[0040] In some embodiments, for example Figure 1As shown, the lower steering column spindle 4 is connected to the steering column housing 1 through the lower steering column spindle bearing 12.

[0041] In some embodiments, for example Figures 1 to 3 As shown, the steering column tube 2 and the upper steering column spindle 3 are connected through the upper bearing 9 and the lower bearing 10 of the upper steering column spindle to ensure the connection stability between the steering column tube 2 and the upper steering column spindle 3.

[0042] Furthermore, the first drive assembly 5 includes a first linear motor 51 and a first secondary transmission rod 52. The first linear motor 51 is installed on the steering column housing 1. One end of the first secondary transmission rod 52 is drivingly connected to the first linear motor 51, and the other end is fixedly connected to the steering column tube 2 to drive the steering column tube 2 to reciprocate axially. In some embodiments, for example Figure 1 As shown, when the first drive assembly 5 operates, the first linear motor 51 is energized and runs, and drives the first secondary transmission rod 52 to reciprocate axially; the first secondary transmission rod 52 is rigidly connected to the steering column tube 2, so that the first secondary transmission rod 52 can synchronously drive the steering column tube 2 to reciprocate axially, and further, the upper steering column spindle 3 installed in the steering column tube 2 can also synchronously perform reciprocating motion axially to realize the adjustment of the steering wheel 13 installed on the upper steering column spindle 3 axially.

[0043] It should be noted that the adjustment of the steering wheel 13 axially is the adjustment of the steering wheel 13 in the front-rear direction of the vehicle body.

[0044] In the prior art, the direction adjustment of the steering wheel mostly uses manual adjustment or rotary electric adjustment. Among them, the adjustment accuracy of manual adjustment is difficult to control, the adjustment limitations are large, it is not easy to adjust the steering wheel to a comfortable position, affecting the driving experience; the rotary electric adjustment has a complex structure, high cost, and requires a large installation space.

[0045] According to the steering column assembly 100 of the embodiment of the present invention, by setting the steering column assembly 100, the accuracy of the direction adjustment of the steering wheel 13 can be improved, the steering wheel 13 can be easily adjusted to a comfortable position, enabling the driver to have a better driving experience. In addition, the overall structure of the steering column assembly 100 is relatively simple, with fewer mechanical parts, does not occupy a large installation space, and has a low cost and convenient maintenance.

[0046] In an embodiment of the present invention, as Figures 1 to 7As shown, the first driving component 5 may further include: a first motor mount 53 and a first secondary connecting rod 54; the first motor mount 53 is installed on the outer side wall of the steering column housing 1, and the first linear motor 51 is installed on the first motor mount 53; in this embodiment, the first motor mount 53 can play a role in limiting and fixing the first linear motor 51, so that the first linear motor 51 will not easily shake during operation, preventing it from affecting the direction adjustment of the steering wheel 13.

[0047] Further, both ends of the first secondary connecting rod 54 are respectively connected between the first secondary transmission rod 52 and the steering column tube 2. A first chute matching with the first secondary connecting rod 54 is formed on the tube wall of the steering column housing 1, and the first chute extends along the axial direction. When the first secondary transmission rod 52 makes a reciprocating motion axially under the drive of the first linear motor 51, the first secondary connecting rod 54 makes a reciprocating motion along the defined direction of the first chute under the drive of the first secondary transmission rod 52, so that the steering column tube 2 connected to the first secondary connecting rod 54 also makes a reciprocating motion axially at the same time, to realize the axial adjustment of the steering wheel 13; the setting of the first chute can ensure the stability of the steering column tube 2 when it makes a reciprocating motion axially, playing a guiding role and preventing the steering column tube 2 from deviating during movement.

[0048] In an embodiment of the present invention, as Figures 1 to 7 shown, a steering shaft core spline 8 is installed at the upper end of the lower steering column core 4. A plurality of first meshing teeth 81 extending along the axial direction are provided on the outer peripheral wall of the steering shaft core spline 8, and a plurality of second meshing teeth matching with the first meshing teeth 81 are provided on the inner peripheral wall of the upper steering column core 3. In this embodiment, the upper steering column core 3 is in transmission connection with the lower steering column core 4 through the steering shaft core spline 8. When the upper steering column core 3 rotates, its second meshing teeth on the inner peripheral wall are in gear engagement with the first meshing teeth 81 on the outer peripheral wall of the steering shaft core spline 8, driving the steering shaft core spline 8 to rotate, and further driving the lower steering column core 4 to rotate synchronously. The steering shaft core spline 8 and the lower steering column core 4 can be fixedly connected or detachably connected.

[0049] Further, when the upper steering column core 3 makes a reciprocating motion axially, relative sliding occurs between the second meshing teeth on its inner peripheral wall and the first meshing teeth 81 on the outer peripheral wall of the steering shaft core spline 8, but there is still gear engagement between the first meshing teeth 81 and the second meshing teeth, and they are not completely disengaged, so that the upper steering column core 3 can still drive the lower steering column core 4 to rotate through the steering shaft core spline 8; the setting of the steering shaft core spline 8 plays a role in extending and transmitting the upper steering column core 3, so that when the upper steering column core 3 makes a reciprocating motion axially, it will not be disengaged from the lower steering column core 4 below, thus ensuring the connection stability with the transmission component.

[0050] In one embodiment of the present invention, as Figures 1 to 7 shown, the steering column assembly 100 may further include: an electromagnetic thrust lock 6; the electromagnetic thrust lock 6 is installed on the steering column housing 1, and the electromagnetic thrust lock 6 includes: a mounting base 61, a telescopic rod 62, and a claw 63. The telescopic rod 62 is adapted to perform telescopic movement in the radial direction, and the claw 63 is rotatably installed at the end of the telescopic rod 62 away from the mounting base 61 to lock the steering column tube 2. In this embodiment, the claw 63 rotates along the central axis of the end of the telescopic rod 62 away from the mounting base 61 to clamp the steering column tube 2; the setting of the electromagnetic thrust lock 6 can limit and fix the position of the steering column tube 2 in the axial direction, so that when the steering column tube 2 reciprocates axially to a specified position and the first linear motor 51 stops driving, it will not continue to move axially, ensuring the connection stability between the mandrel 3 on the steering column and the lower transmission component.

[0051] In a specific embodiment of the present invention, as Figures 1 to 7 shown, a plurality of electromagnetic thrust locks 6 are provided, and the plurality of electromagnetic thrust locks 6 are arranged at intervals along the axial direction. Arranging a plurality of electromagnetic thrust locks 6 can further strengthen the restriction and fixation of the steering column tube 2 and prevent the steering column tube 2 from moving axially; arranging the electromagnetic thrust locks 6 at intervals in the axial direction can make the fixation and limit of the steering column tube 2 by the electromagnetic thrust locks 6 more uniform and prevent stress concentration from occurring and damaging the steering column tube 2.

[0052] In one embodiment of the present invention, as Figures 1 to 7 shown, the steering column assembly 100 may further include: a second drive assembly 7, and the second drive assembly 7 includes: a second motor mounting base 71, a second linear motor 72, a second secondary transmission rod 73, and a lever assembly 74; the second motor mounting base 71 is installed on the vehicle body; the second linear motor 72 is installed on the second motor mounting base 71; the second secondary transmission rod 73 is in transmission connection with the second linear motor 72; the lever assembly 74 includes: a lever mounting base 701, a driving lever 702, and a shift lever 703. The lever mounting base 701 is installed on the vehicle body, one end of the driving lever 702 is rotatably connected to the second secondary transmission rod 73, and the other end is provided with the shift lever 703. The shift lever 703 is located below the steering column housing 1 to toggle the steering column housing 1 to rotate upward. In some embodiments, for example Figure 1As shown, when the second linear motor 72 is energized and operates, the second linear motor 72 drives the second secondary transmission rod 73 to perform reciprocating motion along the axial direction; the lever mounting seat 701 can fix the active lever 702 and provide a fulcrum for the active lever 702. The active lever 702 and the lever mounting seat 701 can be rotatably connected; the second secondary transmission rod 73 can drive one end of the active lever 702, causing the active lever 702 to rotate up and down around the lever mounting seat 701, and driving the lever 703 at the other end of the active lever 702 to drive the steering column housing 1 to move up and down (in the vehicle body direction), thereby realizing the adjustment of the steering wheel 13 in the up and down direction on the vehicle body. Such a design has a simple structure, low cost, and does not occupy too much installation space, effectively improving the driving experience of the vehicle occupants.

[0053] In some embodiments, for example Figures 1 to 3 As shown, the lever 703 is rotatably engaged with the lever bearing 11.

[0054] In some embodiments, for example Figures 1 to 3 As shown, the active lever 702 can be designed as a "V"-shaped lever.

[0055] In a specific embodiment of the present invention, as Figures 1 to 7 shown, the lever assembly 74 may further include a driven rod 704; one end of the driven rod 704 is rotatably connected to the lever mounting seat 701, and both ends of the lever 703 are respectively rotatably connected to the active lever 702 and the driven rod 704. In this specific embodiment, the driven rod 704 is symmetrically arranged about the central axis of the upper core shaft 3 of the steering column. The driven rod 704 is rotatably connected to the lever 703 and provides support for the lever 703, so that when the active lever 702 drives the lever 703 to move up and down reciprocally, the lever 703 can apply a driving force to the steering column housing 1 from both sides of the steering column housing 1, thereby ensuring the stability when the steering column housing 1 moves up and down reciprocally, and further making the steering wheel 13 move more smoothly and smoothly during the up and down adjustment, without jitter and tilt.

[0056] In a specific embodiment of the present invention, as Figures 1 to 7 shown, the lever assembly 74 may further include a second secondary connecting rod 705; one end of the second secondary connecting rod 705 is fixedly connected to the second secondary transmission rod 73, and the other end is rotatably connected to the active lever 702. In this specific embodiment, the second secondary connecting rod 705 is arranged radially and perpendicular to the side surface of the active lever 702; the arrangement of the second secondary connecting rod 705 can make the driving of the active lever 702 by the second secondary transmission rod 73 more stable and smooth.

[0057] In a specific embodiment of the present invention, as Figures 1 to 7As shown, the second drive assembly 7 includes a lever electronic locking mechanism 75; the lever electronic locking mechanism 75 is mounted on the second motor mount 71 to lock the active lever 702. In this specific embodiment, the lever electronic locking mechanism 75 can restrict and fix the active lever 702, such that when the active lever 702 rotates around the lever mount 701 to a specified position and the second linear motor 72 stops driving, the active lever 702 will not move axially any further, ensuring the stability of the steering wheel 13 in the up-and-down direction of the vehicle body and preventing the steering wheel 13 from shifting or wobbling.
