DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] Reference below Figure 1-Figure 6A steering column structure 100 of a vehicle and a vehicle according to an embodiment of the utility model are described. The steering column structure 100 can be used to adjust the working angle and height of the steering wheel of the vehicle to change the position of the steering wheel so that drivers of different body shapes can operate the steering wheel.

[0031] like Figure 1-6 As shown, the steering column structure 100 according to the embodiment of the utility model includes: a column outer body 10 and an adjusting bushing 20, the column outer body 10 has a rotating sleeve 11, the rotating sleeve 11 is sleeved on the outside of the adjusting bushing 20 and can rotate relative to the adjusting bushing 20; an adjusting component 30, the adjusting component 30 is arranged on the rotating sleeve 11 and is located radially outside the adjusting bushing 20, the adjusting component 30 abuts against the outer peripheral wall of the adjusting bushing 20 to apply pressure to the adjusting bushing 20.

[0032] Among them, the outer body 10 of the column can have a rotating sleeve 11, which can be arranged on the outside of the adjusting sleeve 20 and can rotate relative to the adjusting sleeve 20. Along the axial direction of the adjusting sleeve 20, support bearings 21 can be respectively provided at both ends of the adjusting sleeve 20, and the support bearings 21 are located between the rotating sleeve 11 and the adjusting sleeve 20.

[0033] During the adjustment process of the steering column structure 100, the support bearing 21 plays a connecting role between the rotating sleeve 11 and the adjusting bushing 20. The inner ring of the support bearing 21 is interference-fitted with the adjusting bushing 20, and the support bearing 21 and the adjusting bushing 20 do not rotate relative to each other during the adjustment process. The outer ring of the support bearing 21 is overfitted with the rotating sleeve 11, and the support bearing 21 and the rotating sleeve 11 rotate relative to each other during the adjustment process to achieve the purpose of adjusting the steering wheel angle of the vehicle. During the long-term use of the vehicle, the outer surface of the support bearing 21 will be worn, so that the outer ring of the support bearing 21 and the rotating sleeve 11 are overfitted and transformed into a clearance fit. As the clearance increases, the steering column structure 100 produces abnormal noise and becomes loose during the driving of the vehicle and the adjustment of the steering wheel, affecting the adjustment function and driving safety of the steering column structure 100. The adjusting component 30 is arranged on the rotating sleeve 11 and is located radially outside the adjusting bushing 20. The adjusting component 30 abuts against the outer peripheral wall of the adjusting bushing 20 to apply pressure to the adjusting bushing 20, which can compensate for the fitting clearance between the adjusting bushing 20 and the column outer body 10, that is, compensate for the fitting clearance between the outer ring of the support bearing 21 and the rotating sleeve 11, thereby eliminating abnormal noise and looseness of the steering wheel adjustment, thereby improving the driving comfort and safety of the driver.

[0034] According to the steering column structure 100 of the vehicle in the embodiment of the utility model, by arranging the adjustment component 30 on the rotating sleeve 11 and being located radially outside the adjustment bushing 20, the adjustment component 30 abuts against the outer peripheral wall of the adjustment bushing 20 to apply pressure to the adjustment bushing 20, which can compensate for the fitting clearance between the adjustment bushing 20 and the column outer body 10, thereby eliminating abnormal noise and looseness of the steering wheel adjustment, thereby improving the driving comfort and safety of the driver.

The mounting portion 13 is connected to the outer peripheral wall of the sleeve body 12 and defines a second mounting hole 131 connected to the first mounting hole 121. At least part of the adjusting assembly 30 is installed in the second mounting hole 131.

[0036] The sleeve body 12 may define a first mounting hole 121, and the shapes of the first mounting hole 121 and the adjusting bushing 20 may be adapted to facilitate the smooth installation of the adjusting bushing 20 in the first mounting hole 121. The mounting portion 13 is connected to the outer peripheral wall of the sleeve body 12, for example, the mounting portion 13 and the sleeve body 12 may be integrally formed, or the mounting portion 13 and the sleeve body 12 may be connected by bonding, but the utility model is not limited thereto, and the mounting portion 13 and the sleeve body 12 may also be connected by other means, as long as the mounting portion 13 is connected to the outer peripheral wall of the sleeve body 12.

[0037] The mounting portion 13 may define a second mounting hole 131 communicating with the first mounting hole 121, and at least a portion of the adjustment component 30 may be mounted in the second mounting hole 131, for example, one-half of the adjustment component 30 may be mounted in the second mounting hole 131, or one-third of the adjustment component 30 may be mounted in the second mounting hole 131, but the utility model is not limited thereto, and the adjustment component 30 may also be entirely mounted in the second mounting hole 131, as long as at least a portion of the adjustment component 30 is mounted in the second mounting hole 131. Thus, the first mounting hole 121 is communicated with the second mounting hole 131, and the adjustment component 30 mounted in the second mounting hole 131 may abut against the outer peripheral wall of the adjustment bushing 20 mounted in the first mounting hole 121 to apply pressure to the adjustment bushing 20, thereby compensating for the matching clearance between the adjustment bushing 20 and the column outer body 10, thereby eliminating the abnormal noise and looseness of the steering wheel adjustment, and thus improving the driving comfort and safety of the driver.

[0038] According to some embodiments of the present invention, Figure 1As shown, the adjustment assembly 30 may include: a compensating pressure block 31, an elastic member 32 and an end cover 33. Along the radial direction of the adjusting bushing 20, the elastic member 32 is located between the compensating pressure block 31 and the end cover 33. The compensating pressure block 31 is located on the side of the elastic member 32 away from the end cover 33 and abuts against the adjusting bushing 20. The end cover 33 is fixed to the mounting portion 13, and the elastic member 32 is compressed between the compensating pressure block 31 and the end cover 33.

[0039] The end cover 33 is fixed to the mounting portion 13, for example, the end cover 33 and the mounting portion 13 may be connected by a snap connection, or the end cover 33 and the mounting portion 13 may be connected by bolts, but the utility model is not limited thereto, and the end cover 33 and the mounting portion 13 may also be connected by other means, as long as the end cover 33 is fixed to the mounting portion 13. The elastic member 32 may be a spring structure, and along the radial direction of the adjustment bushing 20, the elastic member 32 may be located between the compensation pressure block 31 and the end cover 33, and the elastic member 32 is compressed between the compensation pressure block 31 and the end cover 33, and the compensation pressure block 31 is located on the side of the elastic member 32 away from the end cover 33 and abuts against the adjustment bushing 20, and the elastic force of the elastic member 32 presses the compensation pressure block 31, so that the compensation pressure block 31 applies pressure to the adjustment bushing 20, thereby compensating for the matching clearance between the adjustment bushing 20 and the column outer body 10, thereby eliminating the abnormal noise and looseness of the steering wheel adjustment, thereby improving the driving comfort and safety of the driver.

[0040] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the mounting portion 13 may also be provided with a vent hole 14, and a vent hole plug 15 may be assembled on the vent hole 14 to close the vent hole 14. When installing the elastic member 32 into the mounting portion 13, the vent hole plug 15 is removed, and the vent hole 14 is opened for ventilation, so that the air pressure inside and outside the mounting portion 13 is consistent, so as to ensure that the elastic member 32 is smoothly installed between the compensation block 31 and the end cover 33. After the elastic member 32 is installed, the vent hole plug 15 is installed on the vent hole 14 for sealing, so as to prevent impurities from entering the steering column structure 100 and damaging the steering column structure 100, thereby improving the safety and reliability of the steering column structure 100.

[0041] According to some embodiments of the present invention, Figure 6 As shown, a first assembly groove 311 is formed on the surface of the compensating pressure block 31 facing the adjusting bushing 20 , and a portion of the adjusting bushing 20 is assembled in the first assembly groove 311 . The shape of the first assembly groove 311 matches the shape of the adjusting bushing 20 .

[0042] Among them, the surface of the compensation pressure block 31 facing the adjustment bushing 20 can form a first assembly groove 311, and part of the adjustment bushing 20 can be assembled in the first assembly groove 311, for example: one-third of the adjustment bushing 20 can be assembled in the first assembly groove 311, or one-quarter of the adjustment bushing 20 can be assembled in the first assembly groove 311, but the utility model is not limited thereto, and other proportions of the adjustment bushing 20 can also be assembled in the first assembly groove 311, as long as part of the adjustment bushing 20 is assembled in the first assembly groove 311. The shape of the first assembly groove 311 can be adapted to the shape of the adjustment bushing 20, so as to facilitate the smooth assembly of part of the adjustment bushing 20 in the first assembly groove 311, so that the compensation pressure block 31 can abut against the outer peripheral wall of the adjustment bushing 20 to apply pressure to the adjustment bushing 20, thereby effectively compensating for the matching clearance between the adjustment bushing 20 and the column outer body 10, thereby eliminating the abnormal noise and looseness of the steering wheel adjustment, and thus improving the driving comfort and safety of the driver.

[0043] According to some embodiments of the present invention, Figure 1 As shown, the surface of the compensating pressure block 31 facing away from the adjusting bushing 20 forms a second assembly groove 312 , and the end of the elastic member 32 facing away from the end cover 33 is assembled in the second assembly groove 312 .

[0044] Among them, a second assembly groove 312 can be formed on the surface of the compensation pressure block 31 away from the adjusting bushing 20, and the shape of the second assembly groove 312 can be adapted to the shape of the elastic member 32, so as to facilitate the end of the elastic member 32 away from the end cover 33 to be smoothly assembled in the second assembly groove 312, so that the second assembly groove 312 limits the elastic member 32, and can prevent the elastic member 32 from separating from the compensation pressure block 31, thereby ensuring that the end of the elastic member 32 abuts against the compensation pressure block 31, and the elastic force of the elastic member 32 can press the compensation pressure block 31, so that the compensation pressure block 31 applies pressure to the adjusting bushing 20, thereby further effectively compensating for the fitting clearance between the adjusting bushing 20 and the column outer body 10, thereby further eliminating abnormal noise and looseness of the steering wheel adjustment, thereby further improving the driving comfort and safety of the driver.

[0045] According to some embodiments of the present invention, Figure 1 As shown, a third assembly groove 331 is formed on the surface of the end cover 33 facing the adjustment bushing 20 , and the end of the elastic member 32 facing away from the compensation pressure block 31 is assembled in the third assembly groove 331 .

[0046] Among them, a third assembly groove 331 can be formed on the surface of the end cover 33 facing the adjustment bushing 20, and the shape of the third assembly groove 331 can be adapted to the shape of the elastic member 32, and the third assembly groove 331 and the elastic member 32 are arranged correspondingly, so as to facilitate the end of the elastic member 32 away from the compensation pressure block 31 to be smoothly assembled in the third assembly groove 331, so that the third assembly groove 331 limits the elastic member 32, which can prevent the elastic member 32 from separating from the end cover 33, thereby ensuring that the elastic member 32 is abutted against the end cover 33, and can also offset the elastic force generated after the elastic member 32 is compressed.

[0047] As a result, the elastic member 32 is compressed between the end cover 33 and the compensating pressure block 31, so that the elastic force of the elastic member 32 presses the compensating pressure block 31, and the compensating pressure block 31 applies pressure to the adjusting bushing 20, thereby further eliminating abnormal noise and looseness of the steering wheel adjustment, thereby further improving the driving comfort and safety of the driver.

[0048] According to some embodiments of the present invention, Figure 4 As shown, a guide column 334 is formed on the surface of the end cover 33 facing the adjusting bushing 20 . The guide column 334 extends radially along the adjusting bushing 20 . The compensating pressing block 31 is formed with a guide hole 313 . The guide column 334 is assembled in the guide hole 313 .

[0049] The surface of the end cover 33 facing the adjustment bushing 20 may form a guide column 334, the elastic member 32 is sleeved on the guide column 334, and the two ends of the elastic member 32 are respectively assembled in the second assembly groove 312 and the third assembly groove 331, so that the elastic member 32 is compressed between the compensation pressure block 31 and the end cover 33. The guide column 334 may extend in the radial direction of the adjustment bushing 20, and the compensation pressure block 31 is formed with a guide hole 313, the shape of the guide hole 313 may be adapted to the shape of the guide column 334, and the guide hole 313 and the guide column 334 are arranged correspondingly, so as to facilitate the smooth assembly of the guide column 334 in the guide hole 313. Therefore, the guide column 334 is assembled in the guide hole 313, so that the guide column 334 can be located between the end cover 33 and the compensation block 31, and the elastic member 32 is sleeved on the guide column 334, so that the elastic member 32 can be compressed between the end cover 33 and the compensation block 31, so that the elastic force of the elastic member 32 presses the compensation block 31, and the compensation block 31 applies pressure to the adjustment bushing 20, thereby further eliminating abnormal noise and looseness of the steering wheel adjustment, thereby further improving the driving comfort and safety of the driver.

[0050] According to some embodiments of the present invention, Figure 3As shown, the end cover 33 may include: a connected end cover body 332 and a limiting portion 333, the end cover body 332 is assembled in the second mounting hole 131 and abuts against the elastic member 32, the limiting portion 333 is located outside the mounting portion 13, and the limiting portion 333 abuts against the end of the mounting portion 13 away from the sleeve body 12.

[0051] The end cap body 332 and the limiting portion 333 are connected, for example, the end cap body 332 and the limiting portion 333 can be integrally formed, or the end cap body 332 and the limiting portion 333 can be welded, but the utility model is not limited thereto, and the end cap body 332 and the limiting portion 333 can also be connected in other ways, as long as the end cap body 332 and the limiting portion 333 are connected. The end cap body 332 can be assembled in the second mounting hole 131, and the end cap body 332 abuts against the elastic member 32, so that the end cap body 332 presses the elastic member 32 against the compensation block 31, so that the compensation block 31 can apply pressure to the adjustment bushing 20.

[0052] The limiting portion 333 is located outside the mounting portion 13, and the limiting portion 333 abuts against the end of the mounting portion 13 away from the sleeve body 12, so that the outer surface of the end cover 33 is located outside the mounting portion 13, thereby facilitating the disassembly and installation of the end cover 33, and improving the convenience of disassembly and assembly of the steering column structure 100. In addition, the abutment of the limiting portion 333 with the end of the mounting portion 13 away from the sleeve body 12 can effectively prevent the end cover 33 from moving into the second mounting hole 131, thereby preventing the assembly failure of the end cover 33 and the second mounting hole 131, thereby preventing the end cover 33 from squeezing and damaging other components inside the second mounting hole 131, thereby improving the safety and reliability of the steering column structure 100.

[0053] According to some embodiments of the present invention, Figure 3 As shown, a press-fitting groove 337 may be formed on the outer surface of the end cover body 332 so that the installer can use a tool to abut the press-fitting groove 337 to quickly press the end cover 33 into the installation portion 13, thereby increasing the assembly speed of the steering column structure 100 and reducing the production cost of the steering column structure 100.

[0054] According to some embodiments of the present invention, Figure 3 As shown, the outer surface of the end cover body 332 may further be formed with a weight-reducing hole 338 to reduce the weight of the end cover 33 , thereby reducing the mass of the steering column structure 100 , thereby reducing the manufacturing cost of the steering column structure 100 .

[0055] According to some embodiments of the present invention, Figure 1As shown, the outer peripheral wall of the end cover body 332 forms one of the limiting groove 335 and the limiting boss 133, and the inner peripheral wall of the second mounting hole 131 forms the other of the limiting groove 335 and the limiting boss 133. The limiting boss 133 is assembled in the limiting groove 335 to limit the end cover 33 from moving in the direction away from the adjustment bushing 20.

[0056] Among them, the outer peripheral wall of the end cover body 332 can form one of the limiting groove 335 and the limiting boss 133, and the inner peripheral wall of the second mounting hole 131 can form the other of the limiting groove 335 and the limiting boss 133. This application takes the example of the limiting groove 335 formed on the outer peripheral wall of the end cover body 332 and the limiting boss 133 formed on the inner peripheral wall of the second mounting hole 131 as an example for explanation. The shape of the limiting groove 335 can be adapted to the shape of the limiting boss 133, and the limiting groove 335 and the limiting boss 133 can be correspondingly arranged, so as to facilitate the smooth assembly of the limiting boss 133 in the limiting groove 335, prevent the elastic member 32 from falling out, and offset the elastic force generated by the elastic member 32 after being compressed, thereby limiting the end cover 33 from moving in the direction away from the adjustment bushing 20, thereby improving the safety and reliability of the steering column structure 100.

[0057] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the inner peripheral wall of the second mounting hole 131 may also be formed with a positioning ring groove 132, and the positioning ring groove 132 may be constructed as a limiting groove, the end cover body 332 may be formed with a limiting protrusion, and the end cover body 332 may also be formed with a guiding slope 336. When the end cover body 332 is installed in the second mounting hole 131, the guiding slope 336 can play a guiding role, so that the end cover body 332 can be quickly assembled in the second mounting hole 131, and the limiting protrusion of the end cover body 332 is adapted and limitedly matched with the limiting groove of the positioning ring groove 132, so that the positioning ring groove 132 positions and limits the end cover body 332, thereby preventing the end cover 33 from being displaced or shaken in the second mounting hole 131, thereby further improving the safety and reliability of the steering column structure 100.
