DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments (or, modes) of the present application will be described clearly and completely in conjunction with the drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0035] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0036] Some vehicles have steering column angle adjustment functions to adapt to the user's driving needs. Currently, when the steering column is adjusted, the intermediate shaft assembly swings, which may cause interference and reduce the vehicle's safety performance.

[0037] like Figure 1 and Figure 2 As shown, this application discloses a steering column assembly, including a body assembly 10, a column mount 20, and a steering column 30. The body assembly 10 is used to connect to the vehicle body. The column mount 20 is fixed to the body assembly 10. The steering column 30 is assembled to the column mount 20.

[0038] The steering column 30 includes a column body 31 and a connecting bracket 32. The connecting bracket 32 ​​is fixed to the column body 31. A fork mounting portion 301 and a steering wheel mounting portion 302 are respectively provided at both ends of the steering column 30. The connecting bracket 32 ​​is rotatably connected to the column mounting member 20. Please refer to the following: Figure 5 As shown, the fork mounting part 301 is used to mount the fork 90 of the intermediate shaft assembly.

[0039] The axis of rotation between the connecting bracket 32 ​​and the pipe column mounting component 20 is arranged radially along the pipe column body 31. The radial direction of the pipe column body 31 is... Figure 1 The X direction is shown in the diagram. The axis of rotation is... Figure 2 The L1 axis shown is located on the side of the fork mounting portion 301 away from the steering wheel mounting portion 302, so that the rotation axis can coincide with the rotation axis of the fork 90.

[0040] like Figure 1 , Figure 2 and Figure 5 As shown, by setting the rotation axis on the side of the fork mounting portion 301 away from the steering wheel mounting portion 302, when the steering column assembly and the intermediate shaft assembly are assembled, a suitable fork can be selected so that the rotation axis coincides with the rotation axis of the fork. The coincided axis... Figure 5 The axis of rotation is represented by L1.

[0041] When the steering column assembly is angle-adjusted, the steering column 30 rotates around the coincident axis. Therefore, the intermediate shaft assembly is not affected to swing, avoiding the interference of parts and the change of steering torque fluctuation. For the three-joint intermediate shaft assembly, the traditional steering column assembly cannot be angle-adjusted because the intermediate shaft is fixed. In the present application, the rotation of the steering column 30 does not require the intermediate shaft to change the posture, so the angle adjustment can be performed, expanding the application range of the steering column assembly.

[0042] As shown in Figure 5 , the present application also provides a vehicle comprising the intermediate shaft assembly (not shown in the figure) and the above-mentioned steering column assembly. The intermediate shaft assembly comprises the knuckle 90 assembled to the knuckle mounting portion 301. The rotation axis of the connecting bracket 32 and the column mounting piece 20 coincides with the rotation axis of the knuckle 90. Because the steering column assembly does not interfere when angle-adjusted and the steering torque fluctuation is less affected, the vehicle of the present application has high safety performance. The vehicle of the present application can be a passenger car, a commercial vehicle, etc., and the specific type is not limited.

[0043] As shown in Figure 1 and Figure 2 , the vehicle body assembly 10 can comprise a first assembly bracket 11 and a second assembly bracket 12. The first assembly bracket 11 and the second assembly bracket 12 can be in a strip shape and are spaced apart along the axial direction of the steering column 30 to improve the fixing effect of the steering column assembly and the vehicle body. The first assembly bracket 11 is provided with a first mounting hole 111. The second assembly bracket 12 is provided with a second mounting hole 121. The steering column assembly can be assembled to the dashboard of the vehicle through the first mounting hole 111 and the second mounting hole 121.

[0044] As shown in Figure 1 and Figure 2 , the number of column mounting pieces 20 is set to one pair, and the pair of column mounting pieces 20 is distributed on both sides of the column body 31 in the radial direction. The number of connecting brackets 32 is set to one pair, and the pair of connecting brackets 32 is distributed on both sides of the column body 31 in the radial direction. The column mounting piece 20 and the connecting bracket 32 on the same side of the column body 31 in the radial direction are rotationally connected.

[0045] That is, the two sides of the column body 31 in the radial direction are respectively a first side and a second side, the column mounting piece 20 on the first side is rotationally connected with the connecting bracket 32 on the first side, and the column mounting piece 20 on the second side is rotationally connected with the connecting bracket 32 on the second side. Specifically, the first side and the second side can be symmetrically distributed.

[0046] By setting a pair of column mounting members 20 and a pair of connecting brackets 32, the steering column assembly can be supported from both sides when angle adjustment is performed, improving the strength of the steering column assembly and further improving the safety performance of the vehicle. In other embodiments, the number of column mounting members 20 and connecting brackets 32 is not limited and each can be one or more.

[0047] As shown in Figure 1 and Figure 3 , the column mounting member 20 can include a main body portion 21 and a rotating mounting portion 22 located at one end of the main body portion 21. Specifically, the rotating mounting portion 22 can be located at the end of the main body portion 21 away from the steering wheel mounting portion 302. The rotating mounting portion 22 is rotatably connected to the connecting bracket 32. The main body portion 21 is provided with a sliding groove 211 to guide the rotation of the steering column 30, improving the smoothness of the steering column assembly during angle adjustment and improving user experience. Specifically, a locking mechanism 50 can be installed on the main body portion 21, which can drive the steering column 30 to move along the sliding groove 211.

[0048] In this embodiment, in the view angle perpendicular to the symmetry plane of the pair of column mounting members 20, i.e. in the view angle as shown in Figure 3 , the main body portion 21 is at least partially located on one side of the central axis of the steering column 30. The central axis is the L2 axis as shown in Figure 3 . The rotating mounting portion 22 extends from the main body portion 21 towards the other side of the central axis of the steering column 30. As shown in Figure 2 and Figure 3 , the sliding connection between the steering column 30 and the sliding groove 211, the rotating connection between the column body 31 and the connecting bracket 32, and the connection between the main body portion 21 and the rotating mounting portion 22 form a triangle, further enhancing the stability of the steering column 30 during rotation. The specific structure of the column mounting member 20 is not limited.

[0049] The column mounting member 20 is provided with a first fixing lug 23 and a second fixing lug 24. The first fixing lug 23 and the first assembly bracket 11 can be fixed by welding. The second fixing lug 24 and the second assembly bracket 12 can also be fixed by welding. To reduce burrs and improve strength, the column mounting member 20 can be provided with an arc-shaped flange 25. Reinforcing ribs 26 are provided on the rotating mounting portion 22 and the second lug 24 to further improve the strength of the steering column assembly and improve the safety of the vehicle.

[0050] As shown in Figure 3As shown, the column body 31 can include an outer column tube 311, an inner column tube 312, and a mounting base 313. The inner column tube 312 is sleeved and mounted in the outer column tube 311, and the two are connected through a deep groove ball bearing and fixed by a clamping spring. The mounting base 313 is arranged on the side of the outer column tube 311 away from the inner column tube 312. When the vehicle is impacted, the inner column tube 312 can move in the axial direction to absorb a certain amount of energy. However, in order to ensure safety, the steering column assembly needs to maintain a certain axial size and cannot completely collapse. Therefore, a structure for increasing the retaining force needs to be arranged on the steering column assembly.

[0051] In an embodiment, the steering column assembly can further include a retaining structure 40. The retaining structure 40 is fixed to the outer column tube 311 and abuts the inner column tube 312 in the radial direction. By arranging the retaining structure 40, a retaining force is provided to the inner column tube 312, the strength of the steering column assembly is improved, the steering column assembly is prevented from completely collapsing when the vehicle is impacted, and the safety performance of the vehicle is further improved.

[0052] As shown in Figure 1 , Figure 4 and Figure 5 , the outer column tube 311 can be in a U shape and include a first plate member 3111, a second plate member 3112, and a third plate member 3113. The first plate member 3111 and the second plate member 3112 are arranged opposite to each other, and the third plate member 3113 is in an arc shape and connects the first plate member 3111 and the second plate member 3112. The outer column tube 311 can be provided with a pressing structure 3114. The pressing structure 3114 abuts the inner column tube 312 to provide a certain retaining force and increase the safety of the vehicle. The pressing structure 3114 can be a pressing plate, a pressing block, or the like.

[0053] In an embodiment, the outer column tube 311 can be provided with a limiting plate 3115. The limiting plate 3115 is fixed in abutment with the retaining structure 40 in the axial direction of the outer column tube 311. By arranging the limiting plate 3115, the assembly efficiency of the retaining structure 40 is improved.

[0054] Since the limiting plate 3115 is fixed in abutment with the retaining structure 40 in the axial direction, the force exerted by the retaining structure 40 on the inner column tube 312 in the radial direction is not affected, and the size of the retaining force is ensured. At the same time, since the limiting plate 3115 axially limits the retaining structure 40, the steering column assembly can also be retained to a certain extent, preventing the inner column tube 312 from moving too far in the axial direction.

[0055] Specifically, the limiting plate 3115 can connect the first plate member 3111 and the second plate member 3112. The limiting plate 3115 is provided with a groove structure, and the retaining structure 40 is mounted in the groove structure. The specific structure of the limiting plate 3115 is not limited as long as it can abut the retaining structure 40 in the axial direction.

[0056] AsFigure 2 As shown, the connecting bracket 32 comprises a connecting plate 321. The column mounting 20 is rotatably mounted to one side of the connecting plate 321. A fixing plate 322 is bent from the connecting plate 321 towards the side away from the connecting plate 321. The fixing plate 322 is fixed to the column body 31. The fixing plate 322 can serve as a support to improve the stability of the steering column assembly, further improving the safety performance of the vehicle. The number of fixing plates 322 can be a pair, symmetrically distributed on both sides of the connecting plate 321, so that the connecting bracket 32 is in the shape of a few characters, further improving the stability of the steering column assembly. The fixing plate 322 can be welded to the column body 31.

[0057] To further ensure the stability of the steering column assembly, the collapse peak force of the steering column assembly also needs to be considered. When the impact force acting on the steering column assembly is less than the collapse peak force, the inner column tube 312 does not move. In an embodiment, the steering column 30 can further comprise a pin 33. The pin 33 passes through the outer column tube 311 and the inner column tube 312 in the radial direction to fix the outer column tube 311 and the inner column tube 312.

[0058] By providing the pin 33, when the vehicle is impacted, the steering column assembly is subjected to an impact force, and after the pin 33 is pulled off, the inner column tube 312 can move relative to the outer column tube 311 in the axial direction. The structure of the pin fixation is relatively simple and easy to manufacture. At the same time, the size of the collapse peak force is relatively easy to control. By changing the material ratio or size of the pin 33, the force required to pull off the pin 33 can be changed. For example, Figure 6 As shown, in the embodiment in which the column body 31 comprises a mounting seat 313, the pin 33 passes through the mounting seat 313, the outer column tube 311 and the inner column tube 312. The specific fixation mode of the pin 33 is not limited.

[0059] As shown in Figure 5 and Figure 7 The retaining structure 40 can comprise a compression shaft 41, an elastic member 42 and a retaining member 43. The compression shaft 41 passes through and is fixed to the outer column tube 311. The retaining member 43 abuts against the inner column tube 312. There is a gap between the compression shaft 41 and the retaining member 43, and the elastic member 42 is compressed and installed in the gap and abuts against the compression shaft 41 and the retaining member 43.

[0060] The elasticity of the elastic member 42 provides a retaining force to the inner column tube 312. The stiffness and curvature of the elastic member 42 can be changed according to the demand of the retaining force, which has a high degree of freedom. The compression shaft 41 can pass through the first plate 3111 and the second plate 3112 and be fixed by spin riveting. The elastic member 42 can be a spring. In other embodiments, the specific structure of the retaining structure 40 is not limited.

[0061] In an embodiment, as shown in Figure 8As shown, the retaining structure 40 can include an arc surface 430 facing the inner column tube 312. By providing the arc surface 430, the fitting degree of the retaining structure 40 and the inner column tube 312 can be improved when they are in abutment, and the retaining effect of the retaining structure 40 can be improved. Specifically, the arc surface 430 can be provided on the retaining piece 43.

[0062] In this embodiment, as shown in Figure 9 The arc surface 430 includes a first region 4301 on both sides and a second region 4302 between the two sides. The first region 4301 abuts the inner column tube 312, and the second region 4302 has a gap with the inner column tube 312.

[0063] In production, due to the existence of manufacturing tolerances, when the connection area between the two surfaces is too large, in order to ensure the fitting of the two surfaces, the manufacturing complexity will be greatly increased. Therefore, by appropriately reducing the area of the contact surface, only the first region 4301 abuts the inner column tube 312, the manufacturing difficulty can be reduced, the fitting of the retaining structure 40 and the inner column tube 312 can be better ensured, and the retaining effect can be improved. In some embodiments, the first region 4301 can be provided with a mesh indentation structure to increase the friction between the arc surface 430 and the inner column tube 312, so as to further improve the retaining effect of the retaining structure 40.

[0064] The retaining piece 43 can be made of a powder metallurgy material, which has a simple process and high strength. The specific forming method is not limited. As shown in Figure 8 The retaining piece 43 can include a main body 431 and a clamping jaw 432. The main body 431 abuts the elastic piece 42. The clamping jaw 432 extends from the main body 431 to a direction away from the elastic piece 42. The clamping jaw 432 includes a pair of sub-clamping jaws 4320, which are located on both sides of the inner column tube 312 in the radial direction. By providing the pair of sub-clamping jaws 4320, the force applied by the retaining piece 43 to the inner column tube 312 is increased, and the retaining effect of the retaining structure 40 on the steering column assembly is improved. In other embodiments, the specific structure of the retaining piece 43 is not limited.

[0065] As shown in Figure 5 , Figure 8 and Figure 9 In an embodiment, the number of clamping jaws 432 can be multiple, which includes a first clamping jaw 4321 and a second clamping jaw 4322. The first clamping jaw 4321 is provided on one end of the main body 431 close to the joint fork mounting portion 301, and the second clamping jaw 4322 is provided on one end of the main body 431 close to the steering wheel mounting portion 302. By providing multiple clamping jaws 432, the force that the retaining piece 43 can apply to the inner column tube 312 is further improved, thereby strengthening the retaining effect of the retaining structure 40. In other embodiments, the number and distribution of the clamping jaws 432 are not limited.

[0066] In this embodiment, in the axial direction of the inner column tube 312, the thickness of the second gripper 4322 is less than the thickness of the first gripper 4321. The axial direction of the inner column tube 312 is... Figure 9 The Y direction is shown in the diagram. The steering wheel mounting part 302 is used to assemble the vehicle's steering wheel, and many parts need to be arranged near the steering wheel. Since the second gripper 4322 is close to the steering wheel mounting part 302, by reducing the thickness of the second gripper 4322, it is possible to avoid the parts near the steering wheel and improve the space utilization of the vehicle.

[0067] In the embodiment where the outer column tube 311 is provided with a clamping structure 3114, the number of retaining structures 40 can be at least two, with the two retaining structures 40 respectively arranged on both sides of the clamping structure 3114. By providing retaining force to the inner column tube 312 at multiple locations, the magnitude of the retaining force is increased, thereby improving the strength of the steering column assembly and enhancing vehicle safety.

[0068] Specifically, such as Figure 4 and Figure 5 As shown, the two retaining structures 40 can be located on one side of the clamping structure 3114 in the axial direction, one near the fork mounting portion 301 and the other near the steering wheel mounting portion 302. The two retaining structures 40 can have the same or different structural forms.

[0069] For example, in an embodiment where the retaining structure 40 has a first gripper 4321 and a second gripper 4322 with different thicknesses, only the retaining structure 40 near the steering wheel mounting portion 302 may include a first gripper 4321 and a second gripper 4322 with different thicknesses, while the retaining structure 40 near the fork mounting portion 301 may include a first gripper 4321 and a second gripper 4322 with the same thickness.

[0070] like Figure 7 to Figure 10 As shown, the main body 431 may be provided with a mounting groove 433. The elastic element 42 is assembled into the mounting groove 433, improving installation efficiency. The main body 431 may be provided with a through hole 434, making it easier for the retaining element 43 to deform, increasing the holding force that the retaining structure 40 can apply to the inner column tube 312. The through hole 434 may be round or rectangular, and the two sub-clamps 4320 are connected by an arc-shaped strip structure, further increasing the degree of deformation that the retaining element 43 can produce, and improving the holding force of the retaining structure 40. The main body 431 may be provided with a boss 435, which abuts against the outer surface of the clamping shaft 41, improving the installation efficiency of the clamping shaft 41.

[0071] like Figure 4As shown, the locking mechanism 50 can include a connecting shaft 51, a fixing nut 52, a handle 53 and a cam disc 54. The connecting shaft 51 passes through the first plate 3111 and the second plate 3112. The fixing nut 52 and the handle 53 are assembled to the two ends of the connecting shaft 51, and the cam disc 54 is installed between the handle 53 and the first plate 3111. As shown in Figure 4 and Figure 11 As shown, the handle 53 is provided with a protrusion 531, and the cam disc 54 is provided with a protrusion 541 and a groove 542.

[0072] The user can operate the handle to lock and release the locking mechanism 50. In the locked state, the protrusion 531 and the protrusion 541 abut in the axial direction of the connecting shaft 51, the cam disc 54 pushes the outer column tube 311 to deform, the first plate 3111 and the second plate 3112 are close to each other, and the compression structure 3114 clamps the inner column tube 312. In the released state, the protrusion 531 abuts the bottom of the groove 542, and the outer column tube 311 is in a released state. In the released state, the user can adjust the angle of the steering column.

[0073] As shown in Figure 1 and Figure 2 The mounting seat 313 can be assembled with a wire harness mounting bracket 60 to mount the wire harness of the vehicle and improve the integration of the steering column assembly. The steering column 30 can be provided with a mounting arm 70. The mounting arm 70 and the vehicle body assembly 10 are connected by a spring assembly 80. The spring assembly 80 plays an auxiliary role in the angle adjustment of the steering column assembly, avoiding the steering column 30 from quickly falling along the sliding groove 211 due to gravity. The spring assembly 80 can include a spring 81 and a sound-absorbing sponge 82 sleeved in the spring 81 to reduce noise.
