With the development of autonomous driving, more and more cars are considering the possibility of stowing steering wheels when designing their internal structures. When the steering wheel is not needed for driving, the steering wheel can be stowed into the car's steering wheel storage space by retracting the column. Therefore, the column assembly needs to be retractable. The existing design uses a non-retractable column, which cannot achieve the steering wheel stowage.

In view of this, the present application provides a pipe column assembly and a car, which optimizes space layout and saves costs.

FIG1 is a top view of a pipe column assembly 1 of an embodiment of the present application, FIG2 is a side view of the pipe column assembly 1 of the embodiment shown in FIG1, and FIG3 is a front view of the pipe column assembly 1 of the embodiment shown in FIG1. Referring to FIG1-FIG3, the present application provides a pipe column assembly 1 for use in an automobile, the pipe column assembly 1 includes a pipe column 31 and a telescopic adjustment assembly 2, the telescopic adjustment assembly 2 at least includes a mounting portion 21 connected and fixed to an external structure, a pipe column connection portion 22 connected to the pipe column 31, and a telescopic structure 23 connecting the mounting portion 21 and the pipe column connection portion 22.

In some embodiments, the mounting portion 21 and the column connection portion 22 are both plate-shaped and can slide relative to each other. In this case, the telescopic adjustment assembly 2 is in the form of overlapping upper and lower plates that can slide. In the retracted state, the mounting portion 21 and the column connection portion 22 are stacked, and in the extended state, the mounting portion 21 and the column connection portion 22 do not overlap.

In some embodiments, a spline shaft 311 is provided at the end of the column 31 for mounting a steering wheel (not shown). In this way, the telescopic function of the telescopic adjustment assembly 2 is realized to adjust the distance between the end of the column 31 and the external structure. In some embodiments, the steering wheel storage function can be realized in conjunction with the steering wheel storage space on the car.

Please refer to Figures 1 to 3. In some embodiments, the telescopic structure 23 includes a screw rod 231 and a nut 232 matched with the screw rod 231. One end of the screw rod 231 is fixed to one of the mounting portion 21 and the pipe column connection portion 22, and the nut 232 is fixed to the other of the mounting portion 21 and the pipe column connection portion 22. The nut 232 can be rotatably moved in the length direction of the screw rod 231 to adjust the distance between the pipe column 31 and the external structure. In the illustrated embodiment, the nut 232 is fixed to the pipe column connection portion 22, and one end of the screw rod 231 is fixedly connected to the mounting portion 21. In other embodiments, one end of the screw rod 231 can be fixedly connected to the pipe column connection portion 22, and the nut 232 is fixed to the mounting portion 21, so that the nut 232 can be rotatably moved in the length direction of the screw rod 231. In order to limit the moving distance of the nut 232 on the screw rod 231, the other end of the screw rod 231 in the illustrated embodiment includes a cutoff portion 2311.

The column assembly 1 of the present application uses a telescopic structure 23 including a screw rod 231 and a nut 232. By adjusting the position of the nut 232 on the screw rod 231, the telescopic structure 23 can be extended and retracted, thereby changing the relative stacking position of the mounting portion 21 and the column connecting portion 22, and then adjusting the distance between the end of the column 31 and the external structure, thereby realizing the storable steering wheel function with low cost.

In the illustrated embodiment, the telescopic adjustment assembly 2 further includes a total telescopic motor 24, which includes an output end 241, connected to the nut 232 or the screw 231, driving the nut 232 or the screw 231 to rotate forward or reversely, so that the nut 232 can be rotatably moved in the length direction of the screw 231. In some embodiments, the output end 241 is a snap ring that cooperates with the outer side of the nut 232. Since the nut 232 is fixed to one of the mounting portion 21 and the column connecting portion 22, and one end of the screw 231 is fixed to the other of the mounting portion 21 and the column connecting portion 22, when the total telescopic motor 24 drives the nut 232 or the screw 231 to rotate forward or reversely, the nut 232 can be rotatably moved in the length direction of the screw 231. Since the distance between the nut 232 and one end of the screw 231 changes, the relative position between the mounting portion 21 and the column connecting portion 22 changes, thereby achieving the adjustment of the distance between the end of the column 31 and the external structure. In some embodiments, when the nut 232 rotates forwardly relative to the screw 231, the distance between the nut 232 and one end of the screw 231 becomes smaller, thereby realizing the contraction function of the telescopic structure 23 of the column assembly 1 of the present application; when the nut 232 rotates reversely relative to the screw 231, the distance between the nut 232 and one end of the screw 231 becomes larger, thereby realizing the extension function of the telescopic structure 23 of the column assembly 1 of the present application. In some embodiments, the telescopic adjustment assembly 2 of the present application also includes a telescopic controller for controlling the total telescopic motor 24, which is electrically connected to the total controller of the car, and the driver can operate the telescopic controller to control the forward or reverse rotation and rotation rate of the output end 241 of the total telescopic motor 24. In other embodiments, the nut 232 of the telescopic structure 23 can be adjusted manually.

In some embodiments, the mounting portion 21 is provided with mounting portion limiting portions 211 on both sides perpendicular to the length direction of the screw 231, the pipe column connection portion 22 is clamped between the mounting portion limiting portions 211, and a bearing 212 is provided between the pipe column connection portion 22 and the mounting portion limiting portion 211. In some embodiments, the mounting portion limiting portion 211 is a protrusion extending from the edge of the mounting portion 21 and perpendicular to the mounting portion 21. A groove 213 is provided on the inner side of the mounting portion limiting portion 211, and a groove 213 is also provided on the outer side of the pipe column connection portion 22 (i.e., the side facing the mounting portion limiting portion 211). The bearing 212 is a linear bearing, which is clamped in two grooves 213, and is used to enable the pipe column connection portion 22 and the mounting portion 21 to move relatively smoothly, so as to achieve the adjustment of the length of the pipe column assembly 1 by the telescopic adjustment assembly 2. In some embodiments, the axial adjustment stroke range of the pipe column assembly 1 is +30mm to -200mm. In some embodiments, the linear bearing is arranged in a symmetrical arrangement structure, and the friction of the axial adjustment can be effectively reduced by converting the rolling of the ball into linear motion.

In the illustrated embodiment, the mounting portion 21 includes a first mounting portion 20 and a second mounting portion 25. In the illustrated embodiment, the first mounting portion 20 is connected to the external structure, and the second mounting portion 25 is connected to the pipe column connection portion 22, that is, the second mounting portion 25 is provided between the first mounting portion 20 and the pipe column connection portion 22. In other embodiments, a third mounting portion, a fourth mounting portion, etc. may be provided between the first mounting portion 20 and the second mounting portion 25. In some embodiments, the maximum length of the pipe column assembly 1 remains unchanged, and the mounting portion 21 includes the first mounting portion 20 and the second mounting portion 25, which can significantly reduce the minimum length of the pipe column assembly 1 and improve the contraction ratio; in other embodiments, the maximum length of the pipe column assembly 1 can also be improved by increasing the number of the second mounting portions 25 and increasing the width of the second mounting portions 25. In some embodiments, the first mounting portion 20 and the pipe column connection portion 22 are plate-shaped, and the second mounting portion 25 is also plate-shaped. The three overlap when the telescopic adjustment assembly 2 is contracted, and the second mounting portion 25 is provided between the first mounting portion 20 and the pipe column connection portion 22. Correspondingly, the mounting portion limiting portion 211 includes a first mounting portion limiting portion 201 and a second mounting portion limiting portion 251, and the bearing 212 includes a first bearing 2121 and a second bearing 2122.

In some embodiments, the first mounting portion limiting portion 201 is a protrusion extending from the edge of the first mounting portion 20 and perpendicular to the first mounting portion 20. A groove 213 is provided on the inner side of the first mounting part limit portion 201, and a groove 213 is also provided on the outer side of the second mounting part limit portion 251. The first bearing 2121 is a linear bearing, which is clamped in the two grooves 213, and is used to allow the second mounting part 25 and the first mounting part 20 to move relative to each other smoothly. The second mounting part limit portion 251 is a protrusion extending from the edge of the second mounting part 25 and perpendicular to the second mounting part 25. A groove 213 is provided on the inner side of the second mounting part limit portion 251, and a groove 213 is also provided on the outer side of the column connection portion 22. The second bearing 2122 is a linear bearing, which is clamped in the two grooves 213, and is used to allow the second mounting part 25 and the column connection portion 22 to move relative to each other smoothly. The telescopic adjustment component 2 can smoothly move relative to each other to adjust the length of the pipe column component 1. In some embodiments, a plurality of mounting parts 21 are further included between the first mounting part 20 and the pipe column connecting part 22. The connection mode between the plurality of mounting parts 21 can be set in accordance with the above-mentioned setting mode, so it will not be described in detail. In this way, the telescopic adjustment component 2 can adjust the length of the pipe column component 1.

In some embodiments, the telescopic structure 23 includes a first telescopic structure 233 disposed between the first mounting portion 20 and the second mounting portion 25 and a second telescopic structure 234 disposed between the second mounting portion 25 and the column connecting portion 22. The nut 232 of the first telescopic structure 233 moves in the length direction of the screw 231 of the first telescopic structure 233, and the nut 232 of the second telescopic structure 234 moves in the length direction of the screw 231 of the second telescopic structure 234. In some embodiments, the first telescopic structure 233 and the second telescopic structure 234 both include a nut 232 and a screw 231, which can be specifically arranged according to the arrangement of the telescopic structure 23, that is, the first telescopic structure 233 includes a screw 231 and a nut 232 matched with the screw 231, one end of the screw 231 is fixed to one of the first mounting portion 20 and the second mounting portion 25, the nut 232 is fixed to the other of the first mounting portion 20 and the second mounting portion 25, and the nut 232 is rotatably movable in the length direction of the screw 231; the second telescopic structure 234 includes a screw 231 and a nut 232 matched with the screw 231, one end of the screw 231 is fixed to one of the second mounting portion 25 and the pipe column connection portion 22, the nut 232 is fixed to the other of the second mounting portion 25 and the pipe column connection portion 22, and the nut 232 is rotatably movable in the length direction of the screw 231. In this way, the adjustment of the length of the pipe column assembly 1 of the present application including the second mounting portion 25 is achieved.

Please refer to Figures 1 to 3. In order to control the telescopic movement of the pipe column assembly 1, in some embodiments, the telescopic adjustment assembly 2 further includes a telescopic controller and a total telescopic motor 24. Since in some embodiments the pipe column assembly 1 further includes a second mounting portion 25 and at least two telescopic structures 23, in some embodiments, the telescopic adjustment assembly 2 includes a first telescopic motor and a second telescopic motor (not shown) to control the first telescopic structure 233 and the second telescopic structure 234, respectively. Specifically, the first telescopic motor is used to control the nut 232 or screw 231 of the first telescopic structure 233 to rotate forward or reverse, so that the nut 232 moves in the length direction of the screw 231; the second telescopic motor is used to control the nut 232 or screw 231 of the second telescopic structure 234 to rotate forward or reverse, so that the nut 232 moves in the length direction of the screw 231. In the illustrated embodiment, in order to reduce the volume occupied by the motor and optimize the space layout, one motor can be used to control multiple telescopic structures 23 at the same time. At this time, the telescopic adjustment component 2 includes a total telescopic motor 24 fixed to the second mounting portion 25, and the total telescopic motor 24 includes a first output end 261 and a second output end 262, which respectively control the first telescopic structure 233 and the second telescopic structure 234. Specifically, the first output end 261 is used to control the nut 232 or the screw 231 of the first telescopic structure 233, which is disposed on the second mounting portion 25, to rotate forward or reverse, so that the nut 232 moves in the length direction of the screw 231; the second output end 262 is used to control the nut 232 or the screw 231 of the second telescopic structure 234, which is disposed on the second mounting portion 25, to rotate forward or reverse, so that the nut 232 moves in the length direction of the screw 231. In this way, the telescopic controller only needs to control one total telescopic motor 24 to realize the length adjustment of the tubular column assembly 1 by the telescopic adjustment component 2 of the present application. On the other hand, In the illustrated embodiment, the total telescopic motor 24 is fixed to the second mounting portion 25, and the nut 232 of the first telescopic structure 233 is fixed to the second mounting portion 25, one end of the screw 231 of the first telescopic structure 233 is fixed to the first mounting portion 20, and the first output end 261 of the total telescopic motor 24, that is, the output end 241 for controlling the stroke of the first telescopic structure 233 for adjusting the relative position of the second mounting portion 25 and the first mounting portion 20, is sleeved on the outside of the nut 232 of the first telescopic structure 233 to control the nut 232 to rotatably move on the screw 231; the nut 232 of the second telescopic structure 234 is fixed to the column The connecting part 22, one end of the screw 231 of the second telescopic structure 234 is fixed to the second mounting part 25, at this time, the second output end 262 of the total telescopic motor 24, that is, the output end 241 of the stroke of the second telescopic structure 234 used to adjust the relative position of the second mounting part 25 and the pipe column connecting part 22, is sleeved on the outer side of one end of the screw 231 of the second telescopic structure 234, and the screw 231 is controlled to rotatably move relative to the inner ring of the nut 232, and the relative distance between the nut 232 of the second telescopic structure 234 and one end of the screw 231 is indirectly adjusted to achieve the adjustment of the relative position of the second mounting part 25 and the pipe column connecting part 22. In this way, the pipe column assembly 1 of the present application can control multiple telescopic structures 23 to move by using a total telescopic motor 24 to achieve the adjustment of the pipe column assembly 1 by the telescopic adjustment assembly 2, which saves costs and has reasonable space layout. In other embodiments, the first telescopic structure 233 and the second telescopic structure 234 of the present application can also be adjusted manually, so there is no need for a telescopic controller, and the purely mechanical structure control reliability is high.

Please continue to refer to Figures 1 to 3. In order to further realize the retractable pipe column assembly 1, in addition to satisfying the length adjustment, the angle adjustment must also be achieved. In some embodiments, the pipe column 31 can be connected to the pipe column connection part 22 through a hovering hinge. In the illustrated embodiment, in order to further increase the stability of the connection between the pipe column 31 and the pipe column connection part 22, the pipe column assembly 1 also includes an angle adjustment assembly 3, and the angle adjustment assembly 3 includes a first connector 32 and a second connector 33 connecting the pipe column 31 and the pipe column connection part 22. The first connector 32 is close to one end of the pipe column 31, and the second connector 33 is close to the other end of the pipe column 31. The first connector 32 includes a first shaft 321 fixed to the pipe column connection part 22 and a pipe column sleeve 322 sleeved on the pipe column 31, and the first shaft 321 and the pipe column sleeve 322 are hinged. The second connector 33 includes a second shaft 331 fixed to the pipe column connection part 22, and the second shaft 331 and the pipe column 31 are hinged. In this way, the first rotating shaft 321, the pipe column 31, the second rotating shaft 331 and the pipe column connection part 22 form a four-bar structure. When the mounting part 21 is fixedly connected to the external structure, by adjusting the angle between the first connecting member 32 or the second connecting member 33 and the pipe column connection part 22, a wide range of angle adjustment between the pipe column 31 and the pipe column connection part 22 can be achieved. Since the four-bar structure can adjust the angle between the rods by adjusting the length of one of the rods, in the pipe column assembly 1 of the present application, by making the pipe column sleeve 322 slide on the pipe column 31 and fix it at any position of the pipe column 31 within its sliding range, the length of the part of the pipe column 31 in the four-bar structure is changed, and the angle between the pipe column 31 and the pipe column connection part 22 is adjusted, thereby achieving the angle adjustment function of the angle adjustment component 3 of the pipe column assembly 1 of the present application. In some embodiments, since the angle between the column 31 and the steering wheel is fixed, in order to change the angle between the column 31 and the column connecting portion 22, it is necessary to change the angle between the column sleeve 322 and the column connecting portion 22. At this time, the column 31 may have the problem of axial movement. Since the first rotating shaft 321 is fixed on the pipe column connecting portion 22, an angle adjustment compensation waist hole is also provided at the hinge between the first rotating shaft 321 and the pipe column sleeve 322, thereby avoiding the axial movement of the pipe column 31 when the four-bar linkage structure moves.

In some embodiments, the angle adjustment assembly 3 further includes a sleeve motion structure 34, which is used to control the tubular sleeve 322 to slide on the tubular column 31. The sleeve motion structure 34 includes an angle adjustment screw 341 and an angle adjustment nut 342 that cooperates with the angle adjustment screw 341. One end of the angle adjustment screw 341 is fixed to one of the tubular column 31 and the tubular sleeve 322, and the angle adjustment nut 342 is fixed to the other of the tubular column 31 and the tubular sleeve 322. The angle adjustment nut 342 is rotatably movable in the length direction of the angle adjustment screw 341. The sleeve motion structure 34 is used to adjust the position of the tubular sleeve 322 on the tubular column 31 to adjust the angle between the tubular column 31 and the tubular column connecting portion 22. In this way, the angle adjustment screw 341 and the angle adjustment nut 342 can achieve the angle adjustment of the tubular column assembly 1 of the present application at a lower cost.
