[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figure 1 and Figure 2 As shown, the steering device 100 of the embodiment of the present invention includes a column tube 1, a guide member 2 and a moving assembly 3. The guide member 2 is arranged on at least one side of the column tube 1 in the inner and outer directions. The guide member 2 has a guide portion 201 extending along the length direction of the column tube 1. At least a part of the moving assembly 3 is arranged between the column tube 1 and the guide member 2. The moving assembly 3 includes a sliding member 31 and a matching member 32. The sliding member 31 is connected to the column tube 1, and the matching member 32 is connected to the sliding member 31. The matching member 32 is sandwiched between the guide member 2 and the sliding member 31, and the matching member 32 is slidably matched with the guide member 2 along the length direction of the column tube 1.

[0036] Among them, at least a part of the moving assembly 3 is arranged between the column tube 1 and the guide member 2, which can be understood as: the moving assembly 3 is arranged as a whole between the column tube 1 and the guide member 2; or, a part of the moving assembly 3 is arranged between the column tube 1 and the guide member 2, and another part of the moving assembly 3 is arranged on the side of the guide member 2 away from the column tube 1. The matching member 32 is sandwiched between the guide portion 201 and the sliding member 31, which can be understood as: the matching member 32 is in contact with the guide portion 201 and the matching member 32 is in contact with the sliding member 31.

[0037] Among them, inward can be understood as: the direction close to the center line of the column tube 1 on the plane perpendicular to the length direction of the column tube 1; outward can be understood as: the direction away from the center line of the column tube 1 on the plane perpendicular to the length direction of the column tube 1. The guide member 2 is arranged on at least one side of the inner and outer directions of the column tube 1, which can be understood as: the guide member 2 is only arranged on the inner side of the column tube 1, in which case the guide member 2 is arranged closer to the center line of the column tube 1 relative to the tube wall of the column tube 1; or the guide member 2 is only arranged on the outer side of the column tube 1, in which case the guide member 2 is arranged farther from the center line of the column tube 1 relative to the tube wall of the column tube 1; or the number of the guide members 2 is multiple, wherein a part of the guide members 2 is arranged on the inner side of the column tube 1, and another part of the guide members 2 is arranged on the outer side of the column tube 1.

[0038] The steering device 100 of the embodiment of the present invention is provided with a moving assembly 3 between the guide member 2 and the column tube 1, wherein the sliding member 31 of the moving assembly 3 is connected to the column tube 1, the fitting member 32 is connected to the sliding member 31, and the fitting member 32 is slidably matched with the guide portion 201 of the guide member 2 along the length direction of the column tube 1, so that the column tube 1 can move relative to the guide member 2 along the length direction of the column tube 1, thereby realizing the telescopic movement of the steering device 100. By connecting the sliding member 31 to the column tube 1 and assembling the fitting member 32 between the guide member 2 and the sliding member 31, the column tube 1, the guide member 2 and the moving assembly 3 are assembled. By sandwiching the fitting member 32 between the guide member 2 and the fitting member 32, the connection stiffness between the guide member 2 and the column tube 1 can be ensured.

[0039] Therefore, the machining accuracy requirements for the components of the steering device 100 according to the embodiment of the present invention are relatively low, which is beneficial to reducing the cost of the steering device 100 .

[0040] In the related art, it is necessary to install an adjustment component between two adjacent column tubes of the steering device, and adjust the sliding friction between the two adjacent column tubes through the adjustment component. This results in the need to repeatedly adjust the adjustment component when assembling the steering device so that the sliding friction between the two adjacent column tubes meets the design requirements.

[0041] Optionally, there is an interference fit between the fitting member 32 and the guide member 2 and between the fitting member 32 and the sliding member 31 , and the fitting member 32 is a bushing or a linear bearing.

[0042] For example, the matching member 32 is a bushing, the outer circumference of the bushing is interference fit with the sliding member 31, and the inner circumference of the bushing is interference fit with the guide member 2. For another example, the matching member 32 is a linear bearing, the outer ring of the linear bearing is interference fit with the sliding member 31, and the inner end of the linear bearing is interference fit with the guide member 2.

[0043] Therefore, when assembling the steering device 100, by setting the interference between the fitting 32 and the guide part 201 and between the fitting 32 and the sliding member 31, the sliding friction between the guide member 2 and the column tube 1 can be adjusted, at least the process of adjusting the adjustment component is omitted, which is conducive to improving the assembly efficiency of the steering device 100 and further reducing the cost of the steering device 100. In addition, by setting the fitting 32 as a bushing or a linear bearing, it is conducive to reducing the sliding friction between the fitting 32 and the guide member 2, thereby reducing the sliding friction between the column tube 1 and the guide member 2; on the one hand, the friction noise between the fitting 32 and the guide member 2 can be reduced, thereby reducing the noise of the steering device 100; on the other hand, a driving member with a smaller driving force can be used to drive the column tube 1 to move relative to the guide member 2, which is conducive to reducing the cost and volume of the driving member, and is conducive to further reducing the cost of the steering device 100 and reducing the volume of the steering device 100.

[0044] Alternatively, if Figure 1 and Figure 3 As shown, the steering device 100 includes a screw-nut mechanism 9 and a drive motor 10. The screw-nut mechanism includes a screw and a nut matched with the screw thread. The screw is rotatably connected to the guide member 2, and the nut is connected to the column tube 1. The drive motor 10 is used to drive the screw to rotate.

[0045] By providing the fitting 32 as a bushing or a linear bearing, the motor 10 can be driven with a smaller driving force.

[0046] Optionally, a lubricating medium is provided between the fitting part 32 and the guide part 2 .

[0047] For example, grease is applied between the fitting 32 and the guide member 2 to reduce the friction between the fitting 32 and the guide member 2 , thereby reducing the friction between the column tube 1 and the guide member 2 .

[0048] Therefore, the noise of the steering device 100 can be further reduced, the cost of the steering device 100 can be reduced, and the volume of the steering device 100 can be reduced.

[0049] In some embodiments, Figures 1 to 3 As shown, there are multiple guide members 2, and the multiple guide members 2 are arranged at intervals along the circumference of the column tube 1. There are multiple moving components 3, and the multiple moving components 3 form multiple moving groups, and each moving group includes at least one moving component 3. The multiple moving groups correspond to the multiple guide members 2 one by one, and the matching member 32 in each moving group matches with the guide portion 201 of the corresponding guide member 2.

[0050] For example, Figures 1 to 3As shown, there are three guide members 2 and three moving groups, each moving group includes two moving components 3 , and the matching members 32 of the two moving components 3 in the same moving group are matched with the guide portion 201 of the same guide member 2 .

[0051] By providing multiple guide members 2 and multiple moving components 3, it is beneficial to increase the matching area between the guide member 2 and the column tube 1, and to improve the moving stability between the column tube 1 and the guide member 2, thereby improving the reliability of the steering device 100. In addition, multiple guide members 2 are arranged at intervals along the circumference of the column tube 1, which can increase the support surface between the column tube 1 and the guide member 2, thereby improving the support stability of the column tube 1, and further improving the reliability of the steering device 100. Among them, the support surface is a plane composed of support points, which is a plane surrounded by the lines connecting the outermost support points.

[0052] Optionally, each moving group includes at least two moving components 3 , and the multiple moving components 3 in the same moving group are arranged at intervals along the length direction of the column tube 1 .

[0053] For example, Figure 1 and Figure 3 As shown, each moving group includes two moving components 3 , and the two moving components 3 in the same moving group are arranged at intervals along the length direction of the column tube 1 .

[0054] By configuring each moving group to include two moving components 3 , the matching area between the guide member 2 and the column tube 1 can be further increased, thereby further improving the reliability of the steering device 100 .

[0055] Alternatively, if Figures 2 to 4 As shown, at least one moving group is a first moving group, and the sliding member 31 in the first moving group is a first sliding member 311, and the first sliding member 311 has a guide through hole 3111 that penetrates along the length direction of the column tube 1. The matching member 32 in the first moving group is a first matching member 321, and the first matching member 321 is annular. The guide frame 2 corresponding to the first moving group is a first guide member 21, and the first guide member 21 is a guide rod. The outer peripheral surface of at least a part of the first guide member 21 forms the matching portion 201 of the first guide member 21. The first matching member 321 is sleeved on the corresponding guide member 2, and the first sliding member 311 is sleeved on the corresponding first matching member 321.

[0056] For example, Figures 2 to 4As shown, one of the three moving groups is the first moving group, and the guide member 2 matched with the first moving group is the first guide member 21. The cross section of the first guide member 21 is circular, the cross section of the first matching member 321 is annular, and the cross section of the guide through hole 3111 is circular, so that the first matching member 321 is sleeved on the first guide member 21, and the first sliding member 311 is sleeved on the corresponding first matching member 321. Among them, the outer circumference of the first matching member 321 is interference fit with the guide through hole 3111, and the inner circumference of the first matching member 321 is interference fit with the first guide member 21 and can slide relative to the first guide member 21. At this time, a part of the first moving group is arranged between the column tube 1 and the first guide member 21, and the other part of the first moving assembly is arranged on the side of the first guide member 21 away from the column tube 1.

[0057] Among them, the cross-section of the first guide member 21 can be understood as: the cross-section of the first guide member 21 cut by a plane perpendicular to the length direction of the column tube 1; the cross-section of the first matching member 321 can be understood as: the cross-section of the first matching member 321 cut by a plane perpendicular to the length direction of the column tube 1; the cross-section of the guide through hole 3111 can be understood as: the cross-section of the guide through hole 3111 cut by a plane perpendicular to the length direction of the column tube 1.

[0058] By setting at least one moving group as the first moving group and setting the first moving group as the above-mentioned structure, not only the processing and manufacturing of the first moving group and the guide member 2 corresponding to the first moving group are facilitated, but also the assembly between the first moving group and the corresponding guide member 2 is facilitated, which is conducive to further reducing the cost of the steering device 100.

[0059] Optionally, at least one moving group is a second moving group, the sliding member 31 in the second moving group is a second sliding member 312, the matching member 32 in the second moving group is a second matching member 322, the guide member 2 corresponding to the second moving group is a second guide member 22, and the second guide member 22 is arranged on the outside of the column tube 1. The steering device 100 also includes a mounting frame 4 for connecting to the vehicle body, the mounting frame 4 includes a connecting arm 42, the connecting arm 42 is connected to the second guide member 22, there is a first preset distance between the connecting arm 42 and the second sliding member 312, and there is a second preset distance between the connecting arm 42 and the second matching member 322.

[0060] For example, Figures 1 to 4As shown, two of the three moving groups are the second moving groups, and the guide member 2 corresponding to the second moving group is the second guide member 22. The mounting frame 4 is in the shape of a "F", and the mounting frame 4 includes a main frame body 41 and two connecting arms 42, the two connecting arms 42 are respectively arranged on opposite sides of the main frame body 41, the two connecting arms 42 correspond to the two sliding members 2 one by one, and the second guide member 22 is connected to the corresponding connecting arm 42 by a connecting bolt 43. The first preset spacing between the connecting arm 42 and the second sliding member 312 is equal to the second preset spacing between the connecting arm 42 and the second matching member 322, that is, the first preset spacing and the second preset spacing are both L. At this time, the second moving group can be arranged as a whole between the column tube 1 and the second guide member 22; the second moving assembly can also be arranged in part between the column tube 1 and the second guide member 22, and the other part is arranged on the side of the second guide member 22 away from the column tube 1.

[0061] Therefore, when the mounting frame 4 is connected to the second sliding member 312, it can be avoided that when the column tube 1 moves in the opposite direction along the length of the column tube 1 relative to the second guide member 22, the second matching member 322 and the second sliding member 312 interfere with the mounting frame 4, thereby improving the telescopic adjustment stroke of the steering device 100.

[0062] Alternatively, if Figure 1 As shown, the steering device 100 includes a steering shaft 8 , and the steering shaft 8 is rotatably connected to the column tube 1 .

[0063] Optionally, the second sliding member 312 has a first through slot 3121 extending along the length direction of the column tube 1, and the second matching member 322 has a second through slot extending along the length direction of the column tube 1. The notch of the second through slot and the notch of the first through slot 3121 are both arranged toward the connecting arm 42. The second guide member 22 is a guide rod, and the outer peripheral surface of at least a portion of the second guide member 22 forms the guide portion 201 of the second guide member 22. The second through slot and the first through slot 3121 are both for the corresponding second guide member 22 to pass through.

[0064] For example, Figures 2 to 4 As shown, the two connecting arms 42 are both arranged on the outer side of the corresponding second guide member 22, and the notches of the second through groove and the notches of the first through groove 3121 are both arranged outward. The cross section of the second guide member 22 is circular; the cross section of the second sliding member 312 is an arc shape larger than a semicircle, so that the second sliding member 312 forms a first through groove 3121 with an arc cross section; the cross section of the second matching member 322 is an arc shape larger than a semicircle, so that the second matching member 322 forms a second through groove with an arc cross section. The second matching member 322 is sleeved on the second guide member 22, and the second sliding member 312 is sleeved on the corresponding second matching member 322. Among them, the outer peripheral surface of the second matching member 322 is interference fit with the second sliding member 312, and the inner peripheral surface of the second matching member 322 is interference fit with the second guide member 22 and can slide relative to the second guide member 22.

[0065] Among them, the cross-section of the second guide member 22 can be understood as: the cross-section of the second guide member 22 cut by a plane perpendicular to the length direction of the column tube 1; the cross-section of the second sliding member 312 can be understood as: the cross-section of the second sliding member 312 cut by a plane perpendicular to the length direction of the column tube 1; the cross-section of the second matching member 322 can be understood as: the cross-section of the second matching member 322 cut by a plane perpendicular to the length direction of the column tube 1.

[0066] By setting the second movable group to the above-mentioned structure, when the distance between the connecting arm 42 and the second guide member 22 is small or even zero, it can also be ensured that there is a first preset distance between the connecting arm 42 and the second sliding member 312 and a second preset distance between the connecting arm 42 and the second mating member 322, which is beneficial to improving the structural compactness of the steering device 100, thereby helping to further reduce the volume of the steering device 100.

[0067] Optionally, the cross section of the second guide member 22 is circular, the cross section of the first through slot 3121 is arc-shaped, and the cross section of the second through slot is arc-shaped. The cross section of the first through slot 3121 can be understood as: the cross section of the first through slot 3121 cut by a plane perpendicular to the length direction of the column tube 1; the cross section of the second through slot can be understood as: the cross section of the second through slot cut by a plane perpendicular to the length direction of the column tube 1.

[0068] By setting the first through groove 3121 and the second through groove as the above-mentioned structure, the first through groove 3121 and the second through groove can play the guiding effect of the circular hole while reducing the material consumption of the sliding member 31 and the matching member 32, effectively preventing the column tube 1 from tilting relative to the guide member 2, and further improving the reliability of the steering device 100.

[0069] Alternatively, if Figures 1 to 3 As shown, there are two second guide members 22 and two connecting arms 42 . The two second guide members 22 are respectively arranged on both sides of the column tube 1 in the radial direction. The two connecting arms 42 correspond to the two second guide members 22 one by one, and each connecting arm 42 is connected to the corresponding second guide member 22 .

[0070] The two connecting arms 42 and the two second guide members 22 are provided to increase the connection area between the mounting frame 4 and the guide member 2 , thereby increasing the connection reliability between the mounting frame 4 and the guide member 2 .

[0071] Alternatively, if Figure 2 As shown, each connecting arm 42 is disposed on the outer side of the corresponding second guide member 22 .

[0072] As a result, the notch of the first through slot 3121 and the notch of the second through slot corresponding to the second guide member 22 are both arranged outward, which makes the notches of the two second movable groups corresponding to the two second guide members 22 face oppositely, thereby effectively preventing the two second guide members 22 from detaching from the notches of the corresponding second movable groups.

[0073] Optionally, the steering device 100 further includes a first seat body 5 and a second seat body 6, wherein the first seat body 5 has a connection portion for connecting with the hand feeling simulation unit 7. The first seat body 5 and the second seat body 6 are arranged at intervals along the length direction of the column tube 1. One end of each of the plurality of guide members 2 is connected to the first seat body 5, and the other end of each of the plurality of guide members 2 is connected to the second seat body 6. The guide members 2 and the first seat body 5 and the second seat body 6 may be welded, threaded, or interference fit.

[0074] Therefore, the first seat body 5 and the second seat body 6 are used to connect the plurality of guide members 2 into a whole, which is beneficial to improving the structural strength of the steering device 100 .

[0075] Alternatively, if Figures 1 to 3 As shown, the plurality of guide members 2 are all arranged on the outer side of the column tube 1 , and the second seat body 6 has an escape portion for escaping the column tube 1 .

[0076] By arranging multiple guide members 2 on the outside of the column tube 1, the moving assembly 3 is also arranged on the outside of the column tube 1, which facilitates the installation and fixation of the sliding member 31 and the matching member 32, thereby facilitating the assembly of the steering device 100, which is beneficial to reducing the assembly cost of the steering device 100; on the other hand, when the steering shaft 8 is arranged in the column tube 1, it can avoid the guide member 2 occupying the internal space of the column tube 1, so that the inside of the column tube 1 can be used to arrange the steering shaft 8, and the outside of the column tube 1 is used to arrange the guide member 2, which is beneficial to shortening the length of the steering device 100.

[0077] Alternatively, if Figure 5 As shown, the first guide member 21 includes a first guide section 211 and a first fixed section 212. The radial dimension of the first fixed section 212 is smaller than the radial dimension of the first guide section 211. The first fixed section 212 is connected to the first seat body 5. The end of the first guide section 211 away from the first fixed section 212 is connected to the second seat body 6. The outer peripheral surface of the first guide section 211 forms the matching portion 201 of the first guide member 21.

[0078] Therefore, the first guide member 21 has a simple structure and is easy to manufacture.

[0079] Alternatively, if Figure 6As shown, the second guide member 22 includes a second guide segment 221 and a second fixed segment 222, the radial dimension of the second fixed segment 222 is smaller than the radial dimension of the second guide segment 221, the second fixed segment 222 is connected to the second seat body 6, and one end of the second guide segment 221 away from the second fixed segment 222 is connected to the second seat body 6. The outer peripheral surface of the second guide segment 221 forms the matching portion 201 of the second guide member 22. The second guide segment 221 is provided with a threaded hole 223 threadedly connected to the connecting bolt 43.

[0080] Therefore, the second guide member 22 has a simple structure and is easy to manufacture.

[0081] Alternatively, if Figure 1 and Figure 2 As shown, the first seat body 5 is a fixing plate, and the thickness direction of the fixing plate is consistent with the length direction of the column tube 1. The end surface of the fixing plate away from the guide member 2 forms a connecting portion.

[0082] Therefore, the structure of the first base body 5 is simple, and the processing and manufacturing of the first base body 5 is convenient.

[0083] Alternatively, if Figure 1 and Figure 2 As shown, the second seat body 6 is C-shaped or U-shaped.

[0084] Therefore, the structure of the second base body 6 is simple, and the processing and manufacturing of the second base body 6 is convenient.

[0085] The assembly method of the steering device 100 according to the embodiment of the present invention is as follows:

[0086] The first seat body 5 is connected to the hand feel simulation unit 7, and multiple guide members 2 are connected to the first seat body 5; the matching member 32 is installed in the sliding member 31 connected to the column tube 1, and the guide member 2 is inserted into the matching member 32; multiple guide members 2 are connected to the second seat body 6 to complete the assembly of the steering device 100.

[0087] When the steering device 100 is telescopically adjusted, the screw nut mechanism 9 drives the column tube 1 to move on the guide member 2 along the length direction of the column tube 1. By adjusting the interference between the fitting 32 and the column tube 1 and the guide member 2, the sliding friction between the fitting 32 and the guide member 2 can be adjusted. When the sliding member 31 moves to the second seat body 6, it moves to the upper mechanical position, and when the sliding member 31 moves to the first seat body 5, it moves to the lower limit position.

[0088] The conventional lower column tube is streamlined and designed into the form of a guide member 2, and a sliding member 31 is designed on the column tube 1, the guide member 2 is inserted into the sliding member 31, and a low-friction and wear-resistant mating member 32 is provided between the sliding member 31 and the guide member 2, thereby improving the connection stiffness between the guide member 2 and the column tube 1. Grease is added between the mating member 32 and the guide member 2 for lubrication, and the friction between the mating member 32 and the guide member 2 is further reduced, thereby improving the connection performance after durability. The steering device 100 has a simple structure, a small number of parts, no noise, a small footprint, and a low cost. The sliding friction between the guide member 2 and the column tube 1 can be ensured by designing the interference fit between the mating member 32 and the guide member 2, and no sliding friction adjustment process is required when assembling the steering device 100.

[0089] The vehicle according to the embodiment of the present invention includes the steering device 100 according to any one of the above embodiments.

[0090] Since the steering device 100 according to the embodiment of the present invention has the advantages of low cost, the vehicle according to the embodiment of the present invention has the advantages of low cost, etc.

[0091] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
