DETAILED DESCRIPTION

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

[0035] If there are terms involving directional indications or positional relationships in the embodiments of the present application (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 relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0036] The steering column of some vehicles has an angle adjustment function to adapt to the driving needs of users. At present, when the steering column is adjusted in angle, the intermediate shaft assembly will swing, which may cause interference and reduce the safety performance of the vehicle.

[0037] like Figure 1 and Figure 2 As shown, the present application discloses a steering column assembly, including a vehicle body assembly 10, a column mounting member 20, and a steering column 30. The vehicle body assembly 10 is used to connect the vehicle body. The column mounting member 20 is fixed to the vehicle body assembly 10. The steering column 30 is assembled to the column mounting member 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. The two ends of the steering column 30 are respectively provided with a yoke mounting portion 301 and a steering wheel mounting portion 302. The connecting bracket 32 ​​is rotatably connected to the column mounting member 20. Please refer to Figure 5 As shown, the yoke mounting portion 301 is used to mount the yoke 90 of the intermediate shaft assembly.

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

[0040] like Figure 1 , Figure 2 and Figure 5 As shown, by arranging the rotation axis on the side of the yoke 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 yoke can be selected so that the rotation axis coincides with the rotation axis of the yoke. Figure 5 The rotation axis L1 is used to represent it.

[0041] When the steering column assembly is adjusted in angle, the steering column 30 will rotate around the coincident axis. Therefore, the intermediate shaft assembly will not be affected and will not swing, thus avoiding the interference of parts and the change of steering torque fluctuation. For the three-cardan joint intermediate shaft assembly, the traditional steering column assembly cannot adjust the angle because the intermediate shaft is fixed. In the present application, the rotation of the rotating column 30 does not require the intermediate shaft to change its posture, so the angle can also be adjusted, which expands the application range of the steering column assembly.

[0042] like Figure 5 As shown, the present application also provides a vehicle, including an intermediate shaft assembly (not shown in the figure) and the above-mentioned steering column assembly. The intermediate shaft assembly includes a yoke 90 assembled to the yoke mounting portion 301. The rotation axis of the connecting bracket 32 ​​and the column mounting member 20 coincides with the rotation axis of the yoke 90. Since the steering column assembly does not interfere when adjusting the angle and the steering torque fluctuation is less affected, the vehicle of the present application has a higher 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] like Figure 1 and Figure 2 As shown, the vehicle body assembly 10 may include a first assembly bracket 11 and a second assembly bracket 12. The first assembly bracket 11 and the second assembly bracket 12 may be in the shape of a long strip and 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 instrument panel of the vehicle through the first mounting hole 111 and the second mounting hole 121.

[0044] like Figure 1 and Figure 2 As shown, the number of the pipe column mounting members 20 is set to a pair, and the pair of pipe column mounting members 20 is distributed on both sides of the pipe column body 31 in the radial direction. The number of the connecting brackets 32 is set to a pair, and the pair of connecting brackets 32 is distributed on both sides of the pipe column body 31 in the radial direction. The pipe column mounting members 20 and the connecting brackets 32 located on the same side of the pipe column body 31 in the radial direction are rotatably connected.

[0045] That is, the two sides of the pipe column body 31 in the radial direction are respectively the first side and the second side, the pipe column mounting member 20 located on the first side is rotatably connected to the connecting bracket 32 ​​located on the first side, and the pipe column mounting member 20 located on the second side is rotatably connected to the connecting bracket 32 ​​located on the second side. Specifically, the first side and the second side can be symmetrically distributed.

[0046] By providing 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 adjusting the angle, thereby increasing 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] like Figure 1 and Figure 3 As shown, the column mounting member 20 may include a main body 21 and a rotating mounting portion 22 located at one end of the main body 21. Specifically, the rotating mounting portion 22 may be located at one end of the main body 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 21 is provided with a slide groove 211 to guide the rotation of the steering column 30, thereby improving the smoothness of the steering column assembly during the angle process and improving the user experience. Specifically, by installing a locking mechanism 50 on the main body 21, the locking mechanism 50 can drive the steering column 30 to move along the slide groove 211.

[0048] In this embodiment, in the perspective perpendicular to the symmetry plane of the pair of column mounting members 20, that is, in the perspective Figure 3 From the perspective shown, the main body 21 is at least partially located on one side of the central axis of the steering column 30. The central axis is Figure 3 The rotation mounting portion 22 is formed by extending from the main body portion 21 toward the other side of the central axis of the steering column 30. Figure 2 and Figure 3 As shown, the sliding connection between the steering column 30 and the slide groove 211, the rotation connection between the column body 31 and the connecting bracket 32, and the connection between the main body 21 and the rotating mounting portion 22 form a triangle, which further enhances the stability of the steering column 30 during the rotation process. The specific structural form of the column mounting member 20 is not limited.

[0049] The column mounting part 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. In order to reduce burrs and improve strength, the column mounting part 20 can be provided with an arc-shaped flange 25. Reinforcing ribs 26 are provided on the rotating mounting part 22 and the second lug 24 to further improve the strength of the steering column assembly and improve the safety of the vehicle.

[0050] like Figure 3As shown, the column body 31 may include an outer column tube 311, an inner column tube 312 and a mounting seat 313. The inner column tube 312 is sleeved and installed in the outer column tube 311, and the two are connected by a deep groove ball bearing and fixed with a retaining spring. The mounting seat 313 is arranged on the side of the outer column tube 311 away from the inner column tube 312. When the vehicle is hit, the inner column tube 312 can move axially and absorb a certain amount of energy. However, in order to ensure safety, the steering column assembly needs to maintain a certain axial dimension and cannot be completely collapsed. Therefore, a structure to increase the holding force needs to be provided on the steering column assembly.

[0051] In one embodiment, the steering column assembly may further include a retaining structure 40. The retaining structure 40 is fixed to the outer column tube 311 and radially abuts against the inner column tube 312. By providing the retaining structure 40, a retaining force is provided to the inner column tube 312, thereby improving the strength of the steering column assembly, preventing the steering column assembly from completely collapsing when the vehicle is impacted, and further improving the safety performance of the vehicle.

[0052] like Figure 1 , Figure 4 and Figure 5 As shown, the outer column tube 311 may be U-shaped, and include a first plate 3111, a second plate 3112, and a third plate 3113. The first plate 3111 and the second plate 3112 are arranged opposite to each other, and the third plate 3113 is arc-shaped and connects the first plate 3111 and the second plate 3112. The outer column tube 311 may be provided with a clamping structure 3114. The clamping structure 3114 abuts against the inner column tube 312 to provide a certain holding force and increase the safety of the vehicle. The clamping structure 3114 may be a clamping plate, a clamping block, etc.

[0053] In one embodiment, the outer column tube 311 may be provided with a limiting plate 3115. The limiting plate 3115 is fixedly abutted against the retaining structure 40 in the axial direction of the outer column tube 311. By providing the limiting plate 3115, the assembly efficiency of the retaining structure 40 is improved.

[0054] Since the limiting plate 3115 is axially abutted and fixed with the retaining structure 40, the force applied by the retaining structure 40 to the inner column tube 312 in the radial direction will not be affected, thereby ensuring the magnitude of the retaining force. At the same time, since the limiting plate 3115 axially limits the retaining structure 40, it can also play a certain role in retaining the steering column assembly, preventing the inner column tube 312 from moving too much in the axial direction.

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

[0056] like Figure 2 As shown, the connecting bracket 32 ​​includes a connecting plate 321. The column mounting member 20 is rotatably mounted to one side of the connecting plate 321. A fixing plate 322 is formed by bending the connecting plate 321 toward a side away from the connecting plate 321. The fixing plate 322 is fixed to the column body 31. The fixing plate 322 can play a supporting role, improve the stability of the steering column assembly, and further improve the safety performance of the vehicle. The number of the 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 "J", so as to further improve the stability of the steering column assembly. The fixing plate 322 can be welded and fixed to the column body 31.

[0057] In order to further ensure the stability of the steering column assembly, the peak collapse force of the steering column assembly also needs to be considered. When the impact force on the steering column assembly is less than the peak collapse force, the inner column tube 312 does not move. In one embodiment, the steering column 30 may also include a pin 33. The pin 33 radially passes through the outer column tube 311 and the inner column tube 312 to fix the outer column tube 311 and the inner column tube 312.

[0058] By setting the pin 33, when the vehicle is hit, the steering column assembly is subjected to impact force. Only after the pin 33 is broken can the inner column tube 312 move axially relative to the outer column tube 311. The pin fixing structure is relatively simple and easy to manufacture. At the same time, it is relatively easy to control the magnitude of the collapse peak force. By changing the material ratio or size of the pin 33 and other parameters, the force required to break the pin 33 can be changed. Figure 6 As shown, in the embodiment where the column body 31 includes a mounting seat 313, the pin 33 is disposed through the mounting seat 313, the outer column tube 311 and the inner column tube 312. The specific fixing method of the pin 33 is not limited.

[0059] like Figure 5 and Figure 7 As shown, the retaining structure 40 may include a clamping shaft 41, an elastic member 42 and a retaining member 43. The clamping 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 clamping shaft 41 and the retaining member 43, and the elastic member 42 is compressed and installed in the gap and abuts against the clamping shaft 41 and the retaining member 43.

[0060] The elasticity of the elastic member 42 is used to provide a holding force to the inner column tube 312, and the rigidity and curvature of the elastic member 42 can be changed according to the demand for the holding force, with a high degree of freedom. The clamping shaft 41 can pass through the first plate 3111 and the second plate 3112 and be fixed by riveting. The elastic member 42 can be a spring. In other embodiments, the specific structure of the holding structure 40 is not limited.

[0061] In one embodiment, if Figure 8As shown, the retaining structure 40 may include a curved surface 430 facing the inner column tube 312. By providing the curved surface 430, the fit between the retaining structure 40 and the inner column tube 312 can be improved, thereby improving the retaining effect of the retaining structure 40. Specifically, the curved surface 430 may be provided on the retaining member 43.

[0062] In this embodiment, if Fig. 9 As shown, the arc surface 430 includes a first area 4301 located at two sides and a second area 4302 between the two sides. The first area 4301 abuts against the inner column tube 312, and there is a gap between the second area 4302 and the inner column tube 312.

[0063] In manufacturing, due to the existence of manufacturing tolerances, when the connection area between the surfaces is too large, in order to ensure that the two surfaces fit together, the manufacturing complexity will be greatly increased. Therefore, by appropriately reducing the area of ​​the contact surface, only the first area 4301 abuts the inner column tube 312, which can reduce the manufacturing difficulty, better ensure the fit between the retaining structure 40 and the inner column tube 312, and improve the retaining effect. In some embodiments, the first area 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 member 43 can be made of powder metallurgy material, which has simple process and high strength. The specific molding method is not limited. Figure 8 As shown, the retaining member 43 may include a main body 431 and a clamping jaw 432. The main body 431 abuts against the elastic member 42. The clamping jaw 432 is formed to extend from the main body 431 in a direction away from the elastic member 42. The clamping jaw 432 includes a pair of sub-jaws 4320, and the pair of sub-jaws 4320 are located on both sides of the inner column tube 312 in the radial direction. By providing a pair of sub-jaws 4320, the force applied by the retaining member 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 structural form of the retaining member 43 is not limited.

[0065] like Figure 5 , Figure 8 and Fig. 9 As shown, in one embodiment, the number of the clamping jaws 432 may be multiple, including a first clamping jaw 4321 and a second clamping jaw 4322. The first clamping jaw 4321 is disposed at one end of the main body 431 close to the yoke mounting portion 301, and the second clamping jaw 4322 is disposed at 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 member 43 can apply to the inner column tube 312 is further increased, thereby enhancing 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 clamping jaw 4322 is less than the thickness of the first clamping jaw 4321. Fig. 9 The Y direction shown in FIG. The steering wheel mounting portion 302 is used to assemble the steering wheel of the vehicle, and many components need to be arranged near the steering wheel. Since the second clamping jaw 4322 is close to the steering wheel mounting portion 302, by reducing the thickness of the second clamping jaw 4322, the components near the steering wheel can be avoided, thereby improving 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 the retaining structures 40 can be set to at least two, and the two retaining structures 40 are respectively arranged on both sides of the clamping structure 3114. The retaining force is provided to the inner column tube 312 through multiple positions, the retaining force is increased, the strength of the steering column assembly is increased, and the safety of the vehicle is enhanced.

[0068] Specifically, Figure 4 and Figure 5 As shown, the two retaining structures 40 may be located on one side of the pressing structure 3114 in the axial direction, one close to the yoke mounting portion 301, and the other close to the steering wheel mounting portion 302. The structural forms of the two retaining structures 40 may be the same or different.

[0069] For example: in an embodiment in which the retaining structure 40 has a first clamp 4321 and a second clamp 4322 of different thicknesses, only the retaining structure 40 near the steering wheel mounting portion 302 may include the first clamp 4321 and the second clamp 4322 of different thicknesses, while the retaining structure 40 near the yoke mounting portion 301 includes the first clamp 4321 and the second clamp 4322 of the same thickness.

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

[0071] like Figure 4As shown, the locking mechanism 50 may include a connecting shaft 51, a fixing nut 52, a handle 53 and a cam plate 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 both ends of the connecting shaft 51, and the cam plate 54 is installed between the handle 53 and the first plate 3111.
