[0036] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and more detailed descriptions will be given hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiments

[0037] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0038] First, the terms involved in the present application are explained:

[0039] By - wire steering column: The by - wire steering column cancels the mechanical connection between the steering wheel and the steering wheel, and completely uses electronic signals to control the steering of the wheels. This system detects the driver's steering intention through sensors, and then the electronic control unit (ECU) processes the signals and commands the motor actuator to achieve the steering of the wheels, providing support for autonomous driving technology and functions such as variable steering ratio and integration of advanced driver assistance systems (ADAS).

[0040] Electric power assisted steering column: Also known as the electric power steering system (EPS), it is a system that adds a motor to the traditional mechanical steering system to provide additional assistance. According to the position of the motor and the mechanical structure, it can be divided into column - electric power steering (C - EPS), pinion - electric power steering (P - EPS), and rack - electric power steering (R - EPS). The electric power steering system detects the torque of the driver's steering wheel and the vehicle speed, and the ECU calculates and controls the motor to output corresponding assistance to improve driving comfort and vehicle controllability.

[0041] As described in the background technology, the wire-controlled steering column of the related technology includes an inner column and an outer column. The inner column is slidably arranged in the outer column, thereby providing an axial length adjustment function of the steering column, so that the wire-controlled steering column can dynamically adjust the length of the steering column according to the needs of the driver or the driving status of the vehicle, thereby improving driving comfort and safety; in order to prevent the inner column and the outer column from wearing due to sliding friction in the outer column, a plurality of bearings are arranged in the outer column, and the inner column and the outer column are prevented from wearing by slidingly connecting the inner column to the plurality of bearings.

[0042] However, when the abutment force between the bearing and the inner tube column is large, the inner tube column may not slide smoothly. When the abutment force between the bearing and the inner tube column is small, the bearing may lose its guidance of the inner tube column, reducing the stability of the inner tube column sliding on the bearing.

[0043] In view of the above technical problems, the embodiments of the present application provide a steering column, a steering device and a car, wherein a pad is inserted into the installation opening, the first bearing drives the positioning plate to move toward the insertion hole, so that the positioning plate drives the positioning column to be inserted into the insertion hole, so that the first bearing is installed in the outer column, and a screw plug is threadedly connected to the outer column and drives the screw plug to be screwed on the outer column, so that the screw plug can drive the first bearing to move toward the inner column through the elastic member and the pad, thereby adjusting the abutment force between the first bearing and the inner column. By adjusting the abutment force between the first bearing and the inner column, the steering column can be adjusted at the same time. The contact force between the inner tube column and the second bearing is adjusted at the same time, so as to prevent the contact force between the inner tube column and the first bearing and the second bearing from being too large or too small, prevent the inner tube column from sliding smoothly on the first bearing and the second bearing, and prevent the first bearing and the second bearing from losing the guidance of the inner tube column. By adjusting the contact force between the inner tube column and the first bearing and the second bearing to a balanced state, it is possible to prevent the first bearing and the second bearing from wearing the inner tube column due to excessive contact force with the inner tube column, thereby indirectly extending the service life of the inner tube column, thereby improving the stability of the inner tube column sliding on the first bearing and the second bearing.

[0044] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0045] Combination Figures 1 to 7 , a steering column, comprising:

[0046] An outer pipe column 100 and an inner pipe column 200, wherein the inner pipe column 200 is located inside the outer pipe column 100, and the outer wall of the inner pipe column 200 and the inner wall of the outer pipe column 100 both have first contact surfaces 600 arranged opposite to each other;

[0047] A first bearing 110, at least one of which is provided. The first bearing 110 is provided on a first contact surface 600 of the outer pipe column 100, and the inner pipe column 200 is slidably connected to the first bearing 110;

[0048] The adjustment assembly 300 is configured to drive the first bearing 110 to move closer to or away from the inner pipe string 200 to adjust the abutment force between the first bearing 110 and the inner pipe string 200 .

[0049] In this embodiment, the first bearing 110 includes a plate body 111 and a plurality of roller needles 112 (see FIG. Figure 5 ); In this embodiment, the cross-sections of the outer column 100 and the inner column 200 are both rectangular; four first bearings 110 are provided, and four adjustment assemblies 300 are provided, and the four adjustment assemblies 300 correspond to the four first bearings 110 one by one; one first contact surface 600 is provided for the outer column 100, and one first contact surface 600 is provided for the inner column 200, the first contact surface 600 of the outer column 100 and the first contact surface 600 of the inner column 200 are parallel to each other and arranged opposite to each other, and the first contact surface 600 is located on the inner bottom wall of the outer column 100 and the outer bottom wall of the inner column 200.

[0050] In this embodiment, the steering column may be configured as a wire-controlled steering column, or may be configured as an electronic power-assisted steering column or other types of steering columns.

[0051] By adopting the above technical solution and the setting of the first bearing 110, the wear between the inner pipe column 200 and the outer pipe column 100 can be reduced, and the sliding effect of the inner pipe column 200 in the outer pipe column 100 is indirectly improved; by adopting the setting of the adjustment component 300, the adjustment component 300 can drive the first bearing 110 to approach or move away from the inner pipe column 200, thereby adjusting the abutment force between the inner pipe column 200 and the first bearing 110, thereby preventing the inner pipe column 200 and the first bearing 110 from sliding against each other. If the abutment force is too large or too small, it can prevent the inner tube column 200 from sliding smoothly on the first bearing 110, and can prevent the first bearing 110 from losing its guidance for the inner tube column 200. By adjusting the abutment force between the inner tube column 200 and the first bearing 110 to a balanced state, it can prevent the first bearing 110 from wearing the inner tube column 200 due to excessive abutment force with the inner tube column 200, thereby indirectly extending the service life of the inner tube column 200, thereby improving the stability of the inner tube column 200 sliding on the first bearing 110.

[0052] CombinationFigures 2 to 6 The adjusting assembly 300 includes a spacer 310 and a driving member 320. An installation opening 120 is provided on the outer pipe column 100. The spacer 310 is inserted through the installation opening 120. The first bearing 110 is arranged on the spacer 310. The spacer 310 is arranged on the driving member 320. The driving member 320 is configured to drive the spacer 310 to approach or move away from the inner pipe column 200 so as to adjust the abutting force between the first bearing 110 and the inner pipe column 200.

[0053] In this embodiment, the spacer 310 is integrally rectangular. A groove 311 is provided on the surface of the rectangular spacer 310 facing the inner pipe column 200. The groove 311 is located in the middle of the spacer 310. Both ends of the groove 311 penetrate through the spacer 310. The cross-section of the groove 311 is rectangular. By adopting the groove 311, the raw material used for manufacturing the spacer 310 is reduced. And by the two sides of the groove 311 on the spacer 310 abutting against the plate body 111 of the first bearing 110, the abutting effect between the spacer 310 and the first bearing 110 is improved.

[0054] By adopting the above technical solution, the driving member 320 drives the spacer 310 to approach or move away from the inner pipe column 200. Since the first bearing 110 is arranged on the spacer 310, the spacer 310 can drive the first bearing 110 to approach or move away from the inner pipe column 200, thereby adjusting the abutting force between the first bearing 110 and the inner pipe column 200. By inserting the spacer 310 through the installation opening 120, the spacer 310 does not occupy the space on the inner wall of the outer pipe column 100, does not affect the dimension setting of the inner pipe column 200, and the structure of the spacer 310 and the installation opening 120 is simple, which is convenient for the production and processing of the spacer 310 and the installation opening 120.

[0055] Combined Figures 2 to 6 The driving member 320 includes a plug 321, and the plug 321 is inserted through and threadedly connected to the outer pipe column 100.

[0056] In this embodiment, a sleeve can be integrally provided with the outer pipe column 100 on the outer wall of the outer pipe column 100. The sleeve communicates with the installation opening 120. By inserting the plug 321 through and threadedly connecting it in the sleeve, the plug 321 is threadedly connected to the outer pipe column 100 through the sleeve.

[0057] By adopting the above technical solution, with the arrangement of the screw plug 321, by driving the screw plug 321 to rotate or reverse-rotate on the outer pipe column 100, the screw plug 321 can drive the first bearing 110 to approach or move away from the inner pipe column 200 through the spacer 310. The screw plug 321 can be automatically fixed at any moved position, so that the screw plug 321 drives the first bearing 110 to be fixed at the adjusted position, without the need for other fixing components to fix the position of the first bearing 110 after movement, improving the abutting effect between the inner pipe column 200 and the first bearing 110, and indirectly improving the adjustment efficiency of the first bearing 110.

[0058] Combined with Figures 2 to 6 , the adjusting assembly 300 further includes an elastic member 330. The elastic member 330 is arranged between the spacer 310 and the driving member 320, and the elastic member 330 is configured to be compressed and deformed to bear the load of the inner pipe column 200.

[0059] In this embodiment, the elastic member 330 is set as a disc spring, and the disc spring is arranged in a ring shape; in other embodiments, the elastic member 330 can also be replaced with a spring or other elastic members.

[0060] By adopting the above technical solution, with the arrangement of the disc spring, when the inner pipe column 200 is stationary within the outer pipe column 100, the pressure of the inner pipe column 200 on the first bearing 110 can be transmitted to the disc spring at this time. The disc spring can be compressed and deformed to bear the load of the inner pipe column 200 in the stationary state, preventing damage to the first bearing 110 and the inner pipe column 200 due to excessive pressure; when the inner pipe column 200 moves within the outer pipe column 100, the disc spring can also be compressed and deformed, so that the disc spring converts the abutment between the spacer 310 and the screw plug 321 into an elastic abutment, preventing continuous friction and damage between the spacer 310 and the screw plug 321; and when the abutting force between the inner pipe column 200 and the first bearing 110 is large, the disc spring can automatically compress to adapt to the large abutting force between the inner pipe column 200 and the first bearing 110, thereby further improving the abutting effect between the inner pipe column 200 and the first bearing 110.

[0061] Combined with Figures 2 to 6 , the steering pipe column further includes a positioning assembly 400. The positioning assembly 400 is arranged on each first bearing 110, and the positioning assembly 400 is used to position the position of the first bearing 110 on the outer pipe column 100.

[0062] By adopting the above technical solution, through the arrangement of the positioning component 400, the position of the first bearing 110 on the outer pipe column 100 can be positioned, thereby improving the convenience of installing the first bearing 110. And through the positioning of the position of the first bearing 110, when the inner pipe column 200 moves on the first bearing 110, it is prevented from driving the first bearing 110 to move along the length direction of the outer pipe column 100, thereby improving the fixing strength of the first bearing 110 fixed on the inner wall of the outer pipe column 100.

[0063] Combined with Figures 2 to 6 , the positioning component 400 includes a positioning plate 410 and a positioning column 420. The positioning plate 410 is embedded in the first bearing 110, the positioning column 420 is arranged on the positioning plate 410, and a plug hole 130 is arranged on the inner wall of the outer pipe column 100. The positioning column 420 is configured to be inserted into or disengaged from the plug hole 130 to position or disengage the positioning of the first bearing 110.

[0064] In this embodiment, a receiving groove 113 is arranged on the surface of the plate body 111 of the first bearing 110 facing away from the inner pipe column 200. The receiving groove 113 is used to receive the positioning plate 410, so that when the positioning plate 410 is placed in the receiving groove 113, the first bearing 110 can be in contact with the inner wall of the outer pipe column 100, and the positioning plate 410 is embedded in the plate body 111 of the first bearing 110 through the receiving groove 113; two positioning columns 420 are arranged on each positioning plate 410. The two positioning columns 420 are arranged on the surface of the positioning plate 410 facing away from the inner pipe column 200, and the two positioning columns 420 are respectively located on both sides of the positioning plate 410; the cross section of the positioning column 420 is circular, and the plug hole 130 is arranged in cooperation with the circular positioning column 420; in other embodiments, the number and shape of the positioning columns 420 can be adjusted as needed. For example, the positioning column 420 can be adjusted to three, or the cross section of the positioning column 420 can be set as a rectangle.

[0065] By adopting the above technical solution, by inserting the positioning plate 410 driving the positioning column 420 into the plug hole 130, the positioning column 420 and the plug hole 130 can position the first bearing 110, thereby improving the convenience of installing the first bearing 110; when the positioning column 420 is inserted into the plug hole 130, the positioning column 420 and the plug hole 130 can prevent the first bearing 110 from moving along the length direction of the outer pipe column 100, thereby preventing the inner pipe column 200 from driving the first bearing 110 to move along the length direction of the outer pipe column 100 when moving on the first bearing 110; by adopting the arrangement of the positioning plate 410 and the positioning column 420, the structure is simple and convenient for production and manufacturing.

[0066] Combined with Figures 2 to 7, the steering column further includes a second bearing 140. At least one second bearing 140 is provided. Oppositely arranged second contact surfaces 700 are provided on the outer wall of the inner pipe column 200 and the inner wall of the outer pipe column 100. The second bearing 140 is arranged on the second contact surface 700 of the outer pipe column 100. The inner pipe column 200 is slidably connected to the inside of the outer pipe column 100 through the first bearing and the second bearing 140.

[0067] In this embodiment, two second contact surfaces 700 are provided on the outer pipe column 100, and the two second contact surfaces 700 on the outer pipe column 100 are respectively arranged on both sides of the inner top wall of the outer pipe column 100; two second contact surfaces 700 are provided on the inner pipe column 200, and the two second contact surfaces 700 on the inner pipe column 200 are respectively arranged on both sides of the outer top wall of the inner pipe column 200; the second contact surfaces 700 of the outer pipe column 100 and the inner pipe column 200 are both inclined. The distance between the two second contact surfaces 700 on the outer pipe column 100 increases in the direction approaching the first contact surface 600, and the distance between the two second contact surfaces 700 on the inner pipe column 200 increases in the direction approaching the first contact surface 600; the second contact surfaces 700 of the outer pipe column 100 and the inner pipe column 200 are parallel to each other and oppositely arranged; four second bearings 140 are provided, and two second bearings 140 are respectively arranged on the two second contact surfaces 700 of the outer pipe column 100.

[0068] By adopting the above technical solution, through the arrangement of the second bearing 140, the second bearing 140 can be distributed around the inner pipe column 200 in cooperation with the first bearing, so that the inner pipe column 200 and the outer pipe column 100 are separated from direct contact, thereby further improving the sliding effect of the inner pipe column 200 slidingly connected to the inside of the outer pipe column 100 and preventing the inner pipe column 200 and the outer pipe column 100 from being worn due to direct friction between them; by only arranging the adjusting assembly 300 on the first bearing, when the adjusting assembly 300 drives the first bearing to approach or move away from the inner pipe column 200, the first bearing can drive the inner pipe column 200 to approach or move away from the second bearing 140, thereby realizing the automatic adjustment of the abutting force between the inner pipe column 200 and the second bearing 140, without arranging the adjusting assembly 300 on the second bearing 140, saving costs and improving the convenience of adjusting the abutting force between the inner pipe column 200 and the first bearing and the second bearing 140.

[0069] Combined Figure 2 With FIGS. 7, the steering column further includes a strengthening assembly 500. At least one strengthening assembly 500 is provided. The strengthening assembly 500 is embedded in the first contact surface 600 and the second contact surface 700 of the inner pipe column 200 along the length direction of the inner pipe column 200. Both the first bearing 110 and the second bearing 140 are in contact with the strengthening assembly 500. The inner pipe column 200 is slidably connected to the first bearing 110 and the second bearing 140 through the strengthening assembly 500.

[0070] In this embodiment, four strengthening components 500 are provided. Two of the strengthening components 500 are embedded on the first contact surface 600 of the inner pipe column 200, and the other two strengthening components 500 are respectively arranged on the two second contact surfaces 700 of the inner pipe column 200. Four first bearings 110 correspond to two of the strengthening components 500, and four second bearings 140 correspond to the other two strengthening components 500. In other embodiments, the number of the strengthening components 500 can be set to five, six, etc., or four first bearings 110 can be abutted against the same strengthening component 500.

[0071] By adopting the above technical solution, by embedding the strengthening component 500 along the length direction of the inner pipe column 200 on the outer wall of the inner pipe column 200, the strength of the inner pipe column 200 is indirectly improved. By abutting the first bearing 110 and the second bearing 140 against the strengthening component 500, the first bearing 110 and the second bearing 140 do not directly contact the outer wall of the inner pipe column 200. Through the setting of the strengthening component 500, it is prevented that the first bearing 110 and the second bearing 140 continuously rub against the inner pipe column 200, resulting in wear of the inner pipe column 200, and the strength of the inner pipe column 200 is further improved. And when the strengthening component 500 is worn, by replacing the strengthening component 500, there is no need to replace the inner pipe column 200, and the use effect of the inner pipe column 200 is improved.

[0072] Combined Figures 2 to 7 , the strengthening component 500 includes a strengthening steel plate 510.

[0073] In this embodiment, four grooves 210 are provided on the outer wall of the inner pipe column 200. The four grooves 210 correspond to the four strengthening steel plates 510 one by one. The grooves 210 are used to accommodate the strengthening steel plates 510 so that the strengthening steel plates 510 do not occupy the space on the outer wall of the inner pipe column 200. Positioning rods 511 are arranged on the surface of the strengthening steel plate 510 facing the bottom wall of the groove 210 and on both sides of the strengthening steel plate 510. Positioning grooves are provided on the bottom wall of the groove 210 for the positioning rods 511 to be inserted, so that the positioning grooves and the positioning rods 511 position the strengthening steel plates 510 to prevent the strengthening steel plates 510 from moving along the length direction of the inner pipe column 200.

[0074] By adopting the above technical solution, by adopting the setting of the strengthening steel plate 510, the strengthening steel plate 510 can further improve the strength of the inner pipe column 200. By abutting the first bearing 110 and the second bearing 140 against the strengthening steel plate 510, the steel first bearing 110 and the steel second bearing 140 can abut against the steel strengthening steel plate 510, and the wear between the first bearing 110 and the second bearing 140 and the strengthening steel plate 510 can be reduced.

[0075] In this embodiment, a lubricating layer is provided on the surface of the reinforcing steel plate 510 facing the inner wall of the outer pipe column 100. The lubricating layer is applied to the reinforcing steel plate 510 by means of lubricating oil coating, so as to further reduce the wear between the reinforcing steel plate 510 and the first bearing 110.

[0076] The embodiment of the present application further provides a steering device, including the steering pipe column of any of the above embodiments provided in the steering device.

[0077] Among them, the specific structure of the steering pipe column has been described in detail in the above embodiments, and will not be repeated here one by one.

[0078] The embodiment of the present application further provides a vehicle, including a vehicle body and the steering pipe column of any of the above embodiments provided on the vehicle body.

[0079] Among them, the specific structure of the steering pipe column has been described in detail in the above embodiments, and will not be repeated here one by one.

[0080] The embodiment of the present application provides a vehicle. By providing a steering pipe column, the spacer 310 is inserted into the mounting opening 120, the first bearing 110 drives the positioning plate 410 to move towards the insertion hole 130, so that the positioning plate 410 drives the positioning column 420 to be inserted into the insertion hole 130, so that the first bearing 110 is installed in the outer pipe column 100. By threadedly connecting the plug 321 to the outer pipe column 100 and driving the plug 321 to rotate on the outer pipe column 100, the plug 321 can drive the first bearing 110 to move towards the inner pipe column 200 through the elastic member 330 and the spacer 310, so as to adjust the abutting force between the first bearing 110 and the inner pipe column 200. By adjusting the abutting force between the first bearing 110 and the inner pipe column 200, the abutting force between the inner pipe column 200 and the second bearing 140 can be adjusted at the same time, so as to prevent the abutting force between the inner pipe column 200, the first bearing 110 and the second bearing 140 from being too large or too small, prevent the inner pipe column 200 from sliding smoothly on the first bearing 110 and the second bearing 140, and prevent the first bearing 110 and the second bearing 140 from losing the guidance of the inner pipe column 200. By adjusting the abutting force between the inner pipe column 200 and the first bearing 110 and the second bearing 140 to an equilibrium state, it is possible to prevent the first bearing 110 and the second bearing 140 from wearing the inner pipe column 200 due to too large an abutting force with the inner pipe column 200, indirectly extending the service life of the inner pipe column 200, and thus improving the sliding stability of the inner pipe column 200 on the first bearing 110 and the second bearing 140.
