[0030] With the development of autonomous driving, more and more cars are incorporating retractable steering wheel designs in their interior structures. This allows the steering wheel to be stored in the car's storage space by retracting the column when driving is not required. Therefore, the column assembly needs to be designed to be retractable. Existing designs use non-retractable columns, which cannot achieve steering wheel storage. This application provides a column assembly 1 that optimizes space arrangement and saves costs. Figure 1 This is a top view of a tubular assembly 1 according to an embodiment of this application. Figure 2 for Figure 1 A side view of the tubular column assembly 1 in the illustrated embodiment. Figure 3 for Figure 1 The front view of the tubular assembly 1 in the illustrated embodiment. Please refer to... Figures 1-3This application provides a column assembly 1 for automobiles. The column assembly 1 includes a column 31 and a telescopic adjustment assembly 2. The telescopic adjustment assembly 2 includes at least a mounting portion 21 fixed to an external structure, a column connecting portion 22 connected to the column 31, and a telescopic structure 23 connecting the mounting portion 21 and the column connecting portion 22. In some embodiments, the mounting portion 21 and the column connecting portion 22 are both flat and can slide relative to each other. In this case, the telescopic adjustment assembly 2 is an overlapping, slidable upper and lower flat plate. In the retracted state, the mounting portion 21 and the column connecting portion 22 are stacked. In the extended state, the mounting portion 21 and the column connecting 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). This achieves the telescopic function of the telescopic adjustment assembly 2 to adjust the distance between the end of the column 31 and the external structure. In some embodiments, it can be used in conjunction with the steering wheel storage space in the automobile to achieve a steering wheel storage function.

[0031] Please refer to Figures 1-3 In some embodiments, the telescopic structure 23 includes a screw 231 and a nut 232 that mates with the screw 231. One end of the screw 231 is fixed to one of the mounting part 21 and the column connection part 22, and the nut 232 is fixed to the other of the mounting part 21 and the column connection part 22. In the illustrated embodiment, the nut 232 is fixed to the column connection part 22, and one end of the screw 231 is fixedly connected to the mounting part 21. In other embodiments, the opposite arrangement can be made, as long as the nut 232 can be rotatably moved in the length direction of the screw 231. To limit the movement distance, the other end of the screw 231 in the illustrated embodiment includes a stop part 2311, which is used to limit the movement distance of the nut 232 on the screw 231.

[0032] The column assembly 1 of this application uses a telescopic structure 23 including a screw 231. By adjusting the position of the nut 232 on the screw 231, the telescopic structure 23 can be extended and retracted, changing the relative stacking position of the mounting part 21 and the column connection part 22, thereby adjusting the distance between the end of the column 31 and the external structure, realizing the function of retractable steering wheel, and at low cost.

[0033] In other embodiments, the nut 232 of the telescopic structure 23 can be manually adjusted. In the illustrated embodiment, the telescopic adjustment assembly 2 also includes a main 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 backward, so that the nut 232 can be rotatably moved along the length direction of the screw 231. In some embodiments, the output end 241 is a retaining ring that engages with the outside of the nut 232. Since the nut 232 is fixed to one of the mounting part 21 and the column connection part 22, and one end of the screw 231 is fixed to the other of the column 31 and the mounting part 21, when the main telescopic motor 24 drives the nut 232 or the screw 231 to rotate forward or backward, the nut 232 can be rotatably moved along the length direction of the screw 231. As the distance between the nut 232 and the fixed end of the screw 231 changes, the relative position of the mounting part 21 and the column connection part 22 changes, thereby adjusting the distance between the end of the column 31 and the external structure. In some embodiments, when the nut 232 rotates forward relative to the screw 231, the distance between the nut 232 and the fixed end of the screw 231 decreases, thus realizing the retraction function of the telescopic structure 23 of the column assembly 1 of this application; when the nut 232 rotates backward relative to the screw 231, the distance between the nut 232 and the fixed end of the screw 231 increases, thus realizing the extension function of the telescopic structure 23 of the column assembly 1 of this application. In some embodiments, the telescopic adjustment assembly 2 of this application further includes a telescopic controller for controlling the main telescopic motor 24, which is electrically connected to the main controller of the vehicle. The driver can operate the telescopic controller to control the forward or reverse rotation and rotation rate of the output end 241 of the main telescopic motor 24.

[0034] In some embodiments, the mounting portion 21 has mounting portion limiting portions 211 on both sides perpendicular to the length direction of the screw 231, and the column connecting portion 22 is engaged between the mounting portion limiting portions 211. A bearing 212 is provided between the column connecting portion 22 and the mounting portion limiting portions 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 column connecting portion 22 (i.e., the side facing the mounting portion limiting portion 211). The bearing 212 is a linear bearing, engaged in the two grooves 213, so that the column connecting portion 22 and the mounting portion 21 can move smoothly relative to each other, realizing the adjustment of the length of the column assembly 1 by the telescopic adjustment assembly 2. In some embodiments, the axial adjustment stroke range is +30mm to -200mm. In some embodiments, the linear bearings are arranged in a symmetrical structure, and the rolling of the balls is converted into linear motion, which can effectively reduce the friction of the axial adjustment.

[0035] In the illustrated embodiment, the mounting portion 21 includes a first mounting portion 20 and a second mounting portion 25. In this embodiment, the first mounting portion 20 is connected to an external structure, and the second mounting portion 25 is connected to the column connection portion 22; that is, the second mounting portion 25 is provided between the first mounting portion 20 and the column connection portion 22. In other embodiments, a third mounting portion, a fourth mounting portion, etc., may be included between the first mounting portion 20 and the second mounting portion 25. In some embodiments, the maximum length of the column assembly 1 remains constant, and the mounting portion 21 including the first mounting portion 20 and the second mounting portion 25 can significantly reduce the minimum length of the column assembly 1 and increase the shrinkage ratio. In other embodiments, the maximum length of the column assembly 1 can also be increased by increasing the number of second mounting portions 25 and increasing the width of the second mounting portions 25. In some embodiments, the first mounting portion 20 and the column connecting portion 22 are plate-shaped, and the second mounting portion 25 is also plate-shaped. The three overlap when the telescopic adjustment assembly 2 retracts. The second mounting portion 25 is located in the middle of the first mounting portion 20 and the column connecting 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. The bearing 212 includes a first bearing 2121 and a second bearing 2122. The first mounting portion 20 has first mounting portions on both sides perpendicular to the length direction of the screw 231. The first mounting part 201 is a limiting part 201, and the second mounting part 25 is engaged between the first mounting part limiting parts 201 on both sides of the first mounting part 20. A first bearing 2121 is provided between the second mounting part 25 and the first mounting part limiting part 201. The second mounting part 25 is provided with second mounting part limiting parts 251 on both sides perpendicular to the length direction of the screw 231. The column connecting part 22 is engaged between the second mounting part limiting parts 251 on both sides of the second mounting part 25. A second bearing 2122 is provided between the column connecting part 22 and the second mounting part limiting part 251. 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 inside the first mounting portion limiting portion 201, and a groove 213 is also provided on the outside of the second mounting portion limiting portion 251. The bearing 212 is a linear bearing, which is engaged in the two grooves 213 to allow the second mounting portion 25 and the first mounting portion 20 to move smoothly relative to each other. In some embodiments, the second mounting portion limiting portion 251 is a protrusion extending from the edge of the second mounting portion 25 and perpendicular to the second mounting portion 25. A groove 213 is provided inside the second mounting portion limiting portion 251, and a groove 213 is also provided on the outside of the column connection portion 22. The bearing 212 is a linear bearing, which is engaged in the two grooves 213 to allow the second mounting portion 25 and the column connection portion 22 to move smoothly relative to each other, thereby realizing the adjustment of the column assembly 1 by the telescopic adjustment component 2. In some embodiments, a plurality of mounting portions 21 are further included between the first mounting portion 20 and the column connection portion 22. The connection method between the plurality of mounting portions 21 can be set according to the above-described method, and therefore will not be described again.This allows the telescopic adjustment component 2 to adjust the length of the tubular assembly 1.

[0036] 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 connection 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, both the first telescopic structure 233 and the second telescopic structure 234 include a nut 232 and a screw 231. Specifically, they can be configured according to the above-described arrangement of the telescopic structure 23. That is, the first telescopic structure 233 includes a screw 231 and a nut 232 that mates 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, and the nut 232 is fixed to the other of the first mounting portion 20 and the second mounting portion 25. The nut 232 is rotatably movable along the length of the screw 231. The second telescopic structure 234 includes a screw 231 and a nut 232 that mates with the screw 231. One end of the screw 231 is fixed to one of the second mounting portion 25 and the column connection portion 22, and the nut 232 is fixed to the other of the second mounting portion 25 and the column connection portion 22. The nut 232 is rotatably movable along the length of the screw 231. This achieves adjustment of the length of the column assembly 1 of this application, including the second mounting portion 25.

[0037] Please refer to Figures 1-3In order to control the extension and retraction of the tubing assembly 1, in some embodiments, the extension and retraction adjustment assembly 2 further includes an extension controller and a main extension motor 24. Since in some embodiments the tubing assembly 1 also includes a second mounting part 25 and at least two extension structures 23, in some embodiments, the extension and retraction adjustment assembly 2 includes a first extension motor and a second extension motor (not shown in this embodiment), which respectively control the first extension structure 233 and the second extension structure 234. Specifically, the first extension motor is used to control the nut 232 or screw 231 of the first extension structure 233 to rotate forward or backward, so that the nut 232 moves in the length direction of the screw 231; the second extension motor is used to control the nut 232 or screw 231 of the second extension structure 234 to rotate forward or backward, so that the nut 232 moves in the length direction of the screw 231. In the illustrated embodiment, to reduce the volume occupied by the motor and optimize the space arrangement, one motor can be used to control multiple telescopic structures 23 simultaneously. In this case, the telescopic adjustment assembly includes a main telescopic motor 24 fixed to the second mounting part 25. The main 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 screw 231 of the first telescopic structure 233 located on the second mounting part 25 to rotate forward or backward, 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 screw 231 of the second telescopic structure 234 located on the second mounting part 25 to rotate forward or backward, 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 main telescopic motor 24 to realize the length adjustment of the telescopic adjustment assembly 2 of the column assembly 1 of this application. On the other hand, in the illustrated embodiment, the main telescopic motor 24 is fixed to the second mounting portion 25, while 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. The first output end 261 of the main telescopic motor 24, i.e., the output end 241 of the first telescopic structure 233 that controls 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, controlling the nut 232 to rotatably move on the screw 231; the second telescopic structure 233... Nut 232 of 34 is fixed to the column connection part 22, and one end of screw 231 is fixed to the second mounting part 25. At this time, the second output end 262 of the main telescopic motor 24, that is, the output end 241 of the length of the second telescopic structure 234 that controls the relative position of the second mounting part 25 and the column connection part 22, is sleeved on the outside of one end of screw 231 of the second telescopic structure 234, controlling the screw 231 to rotate rotatably relative to the inner ring of nut 232, indirectly adjusting the relative distance between nut 232 and one end of screw 231, thereby realizing the adjustment of the relative position of the second mounting part 25 and the column connection part 22.Thus, the tubular assembly 1 of this application can use a single main telescopic motor 24 to control the movement of multiple telescopic structures 23, thereby achieving the adjustment of the tubular assembly 1 by the telescopic adjustment component 2, saving costs and providing a reasonable space arrangement. In other embodiments, the first telescopic structure 233 and the second telescopic structure 234 of this application can also be adjusted manually, thus eliminating the need for a telescopic controller and ensuring high reliability of the purely mechanical structure control.

[0038] Please continue to refer to this. Figures 1-3 To further realize the telescopic column assembly 1, in addition to length adjustment, angle adjustment is also required. In some embodiments, the column 31 can be directly connected to the column connection part 22 via a hovering hinge. In the illustrated embodiment, to further increase the stability of the connection between the column 31 and the column connection part 22, the column assembly 1 also includes an angle adjustment assembly 3. The angle adjustment assembly 3 includes a first connector 32 and a second connector 33 connecting the column 31 and the column connection part 22. The first connector 32 is close to the column 31, and the second connector 33 is close to the other end of the column 31. The first connector 32 includes a first rotating shaft 321 fixed to the column connection part 22 and a column sleeve 322 sleeved on the column 31. The first rotating shaft 321 and the column sleeve 322 are hinged. The second connector 33 includes a second rotating shaft 331 fixed to the column connection part 22. The second rotating shaft 331 and the column 31 are hinged. Thus, the first rotating shaft 321, the tube column 31, the second rotating shaft 331, and the tube column connecting part 22 constitute a four-bar linkage. When the tube column connecting part 22 is fixedly connected to the mounting part 21 and fixed to the external structure, a large range of angle adjustment between the tube column 31 and the tube column connecting part 22 can be achieved by adjusting the angle between the first connecting member 32 or the second connecting member 33 and the tube column connecting part 22. Since the four-bar linkage structure can adjust the angle between the members by adjusting the length of one of the bars, in the tube column assembly 1 of this application, by sliding the tube column sleeve 322 on the tube column 31, the length of the tube column 31 portion in the four-bar linkage is changed. The tube column sleeve 322 slides on the tube column 31 and can be fixed at any position with the tube column 31 within its sliding range, adjusting the angle between the tube column 31 and the tube column connecting part 22, thereby realizing the angle adjustment function of the angle adjustment component 3 of the tube column assembly 1 of this application. In some embodiments, since the included angle between the column 31 and the steering wheel is fixed, if the angle between the column 31 and the column connection 22 is changed, the angle between the column sleeve 322 and the column connection 22 will definitely change, and the column 31 will experience axial movement. Since the first rotating shaft 321 is fixed on the column connection 22, and the hinge between the first rotating shaft 321 and the column sleeve 322 is also provided with an angle adjustment compensation hole, the axial movement of the column 31 during the four-bar linkage movement is avoided.

[0039] In some embodiments, the angle adjustment assembly 3 further includes a sleeve movement structure 34 for controlling the sliding of the tubing sleeve 322 on the tubing 31. The sleeve movement 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 tubing 31 and the tubing sleeve 322, and the angle adjustment nut 342 is fixed to the other of the tubing 31 and the tubing sleeve 322. The angle adjustment nut 342 is rotatably movable along the length direction of the angle adjustment screw 341. The sleeve movement structure 34 is used to adjust the position of the tubing sleeve 322 on the tubing 31 to adjust the included angle between the tubing 31 and the tubing connection portion 22.
