DETAILED DESCRIPTION
[0045] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0046] The embodiments of the present application provide a steering column assembly and a vehicle, which can solve the technical problem that a traditional steering column is arranged from top to bottom with a clock spring, a rotation angle sensor, a combination switch and an ignition lock, and these electrical components are arranged separately, occupying a large upper and lower space, resulting in the rotation axis being far away from the steering wheel and the steering wheel being inflexible to adjust.
[0047] First, as Figure 1 、 Figure 2 and Figure 3 As shown, an embodiment of the present application provides a steering column assembly, which includes: a steering column body 1, on which an ignition lock 2 is installed, the installation point of the ignition lock 2 faces the front of the vehicle body, and the length direction of the ignition lock 2 extends along the width direction of the vehicle body; a combination switch 3, a rotation angle sensor 4 and a clock spring 5, along the axial direction of the steering column body 1, the combination switch 3, the rotation angle sensor 4 and the clock spring 5 are coaxially arranged in sequence, the clock spring 5 is installed on the combination switch 3, the combination switch 3 is installed on the steering column body 1, and the rotation angle sensor 4 is installed between the clock spring 5 and the combination switch 3.
[0048] In this embodiment, the combination switch 3, the angle sensor 4, and the clock spring 5 are coaxially arranged along the axis of the steering column body 1, forming a single, integrated component. This design not only simplifies component connections but also reduces space usage. The clock spring 5 is mounted on the combination switch 3, which is then mounted on the steering column body 1, while the angle sensor 4 is cleverly installed between the clock spring 5 and the combination switch 3. The ignition lock 2's mounting point has been changed from the original front to the rear, with the mounting point now facing the front of the vehicle body. The ignition lock 2's length extends along the vehicle's width. This change not only saves mounting space but also provides a more upright position for the ignition lock, further optimizing upper and lower space utilization. Thanks to the three-in-one integrated design, the overall height has been reduced from 92 mm to 62 mm, significantly reducing the height of the steering column assembly, leaving more space for other vehicle components and improving overall vehicle space utilization. The change in the ignition lock installation method frees up space originally required for the ignition lock, further reducing mounting space. Furthermore, the corrected ignition lock position also makes the overall structure of the steering column assembly more compact and rational. In summary, the improved technical solution, through the three-in-one integrated design and the change in the ignition lock installation method, not only simplifies the structure and reduces the height, but also saves installation space, achieving significant technical benefits. These improvements make the steering column assembly more compact and efficient, and enhance the performance and comfort of the entire vehicle.
[0049] In combination with the first aspect, in one embodiment, Figure 2 and Figure 3 As shown, the rotation angle sensor 4 is provided with a first plug interface 401 , and the combination switch 3 is provided with a first plug connector 301 . The rotation angle sensor 4 is inserted into the first plug interface 401 via the first plug connector 301 to be electrically connected to the combination switch 3 .
[0050] In this embodiment, the rotation angle sensor 4 is designed with a first plug interface 401, and the combination switch 3 is correspondingly designed with a first plug connector 301. This design allows the rotation angle sensor 4 to be conveniently inserted into the first plug interface 401 via the first plug connector 301, thereby achieving electrical connection with the combination switch 3. This plug-in connection not only simplifies the installation process but also improves the stability and reliability of the connection. The plug-in connection significantly simplifies the installation process between the rotation angle sensor 4 and the combination switch 3, eliminating the need for complex wiring and securing steps. Simply inserting the plug connector into the plug interface completes the connection, improving production efficiency. The plug-in connection ensures close contact between the rotation angle sensor 4 and the combination switch 3, thereby improving the stability and reliability of the electrical connection. Even in the presence of vibration or impact during vehicle operation, a stable electrical connection is maintained, ensuring accurate signal transmission. When the rotation angle sensor 4 or combination switch 3 needs to be repaired or replaced, the plug-in connection facilitates removal and installation. No need to disassemble the entire steering column assembly; simply disconnecting the plug connector is sufficient, reducing repair costs and time. Because the plug-in connection eliminates the need for additional wiring and mounting space, the spatial layout of the steering column assembly can be further optimized. This makes the steering column assembly more compact, freeing up more space for other vehicle components. In summary, the use of a plug-in connection to connect the steering angle sensor 4 to the combination switch 3 not only simplifies the installation process, improves the stability and reliability of the connection, and saves space required for wiring harness routing. These technical benefits collectively enhance the performance and reliability of the steering column assembly, providing a strong guarantee for safe driving.
[0051] In combination with the first aspect, in one embodiment, Figure 4 and Figure 5 As shown, the combination switch 3 is provided with a second plug interface 302, the clock spring 5 is provided with a third plug interface 501, a plug wiring harness 6 is plugged between the second plug interface 302 and the third plug interface 501, and the second plug interface 302 and the third plug interface 501 face the same side.
[0052] In this embodiment, the combination switch 3 is designed with a second plug-in interface 302, while the clock spring 5 is correspondingly designed with a third plug-in interface 501. Both plug-in interfaces face the same side, facilitating plug-in operation. A plug-in wiring harness 6 tightly connects the second plug-in interface 302 and the third plug-in interface 501, establishing an electrical connection between the combination switch 3 and the clock spring 5. The design of the plug-in interfaces facing the same side, combined with the connection method of the plug-in wiring harness 6, greatly simplifies the connection process between the combination switch 3 and the clock spring 5. This design allows installers to easily align the plug-in interfaces and perform plug-in, improving work efficiency. The plug-in wiring harness 6, as a connecting medium, ensures a stable and reliable electrical connection between the combination switch 3 and the clock spring 5. The design of the plug-in interfaces also takes into account the requirements of anti-loosening and anti-vibration, further enhancing the stability of the connection. When repairing or replacing the combination switch 3 or the clock spring 5, this plug-in connection method makes removal and installation much simpler and faster. Simply disconnect the plug-in wiring harness 6 to easily remove the combination switch 3 or the clock spring 5 from the steering column assembly. Because both connectors face the same side and the patch cord 6 directly connects them, this design helps optimize the steering column assembly's spatial layout, reducing unnecessary wiring and fixings, making the steering column assembly more compact and neat. As a specialized electrical connector with excellent conductivity and insulation properties, the patch cord 6 ensures accurate signal transmission between the combination switch 3 and the clock spring 5, improving the electrical performance of the entire steering column assembly.
[0053] In combination with the first aspect, in one embodiment, Figure 4 、 Figure 5 and Figure 6 As shown, the steering column assembly also includes: a steering column main wiring harness 7, which includes an ignition lock branch wiring harness 701, a combination switch branch wiring harness 702 and a clock spring branch wiring harness 703 that are bundled together; the ignition lock 2 is provided with a fourth plug interface 201 on the side facing the ground, and the plug connector of the ignition lock branch wiring harness 701 is plugged into the fourth plug interface 201; the combination switch 3 is provided with a fifth plug interface 303, and the plug connector of the combination switch branch wiring harness 702 is plugged into the fifth plug interface 303; the clock spring 5 is provided with a sixth plug interface 502 on one side along the width direction of the vehicle body, and the plug connector of the clock spring branch wiring harness 703 is plugged into the sixth plug interface 502.
[0054] In this embodiment, a steering column main wiring harness 7 is designed into the steering column assembly. This main wiring harness includes an ignition lock branch wiring harness 701, a combination switch branch wiring harness 702, and a clock spring branch wiring harness 703, all bundled together. This design allows for more orderly wiring harness management and avoids confusion and entanglement. A fourth plug-in port 201 is provided on the ground-facing side of the ignition lock 2, into which the plug-in connector of the ignition lock branch wiring harness 701 is plugged. This design prevents the turning radius of the wiring harness branches from interfering with the upper shield 13. The combination switch 3 has a fifth plug-in port 303, into which the plug-in connector of the combination switch branch wiring harness 702 is plugged. Simultaneously, a sixth plug-in port 502 is provided on one side of the clock spring 5 along the width of the vehicle body, into which the plug-in connector of the clock spring branch wiring harness 703 is plugged. The sixth plug-in port 502 is designed to avoid interference with the shield 13 and is preferably oriented toward a larger space, such as to the side or downward. The design of the steering column main and branch wiring harnesses provides a clearer and more organized layout within the steering column assembly, avoiding clutter and entanglement, and improving harness management efficiency. The optimized orientation of the connectors eliminates interference between the turning radius of the branch wiring harnesses and the shroud 13, preventing wear and tear that could result, and improving the reliability and stability of the wiring harness connection. The optimized connector position minimizes wiring harness length, saving space within the steering column shroud and improving space utilization.
[0055] Furthermore, the wiring harness is designed to run close to the steering column body 1, which not only makes the wiring harness more concealed but also minimizes the space inside the protective cover 13, improving space utilization. The optimized wiring harness connection design not only improves the performance and reliability of the steering column assembly but also has a positive impact on the performance of the vehicle's electrical system. The neat layout and reliable connection of the wiring harness ensure accurate signal transmission and stable operation of the electrical system.
[0056] Furthermore, the clock spring 5 and the sockets of the combination switch 3 (ie, the sixth socket 502 and the fifth socket 303) are designed to be close to each other, which can shorten the length of the wiring harness to the greatest extent and save space.
[0057] In combination with the first aspect, in one embodiment, Figure 1 、 Figure 7 、 Figure 8 and Figure 9As shown, the steering column body 1 includes a receiving bracket 101, a steering column 102 fixed to the receiving bracket 101, and a guide block 103 fixed to the receiving bracket 101, and the combination switch 3 is fixed to the receiving bracket 101; the receiving bracket 101 is provided with two mounting holes 1011, and the ignition lock 2 is provided with two mounting slots, and the mounting hole 1011 and the corresponding mounting slot are coaxially provided with a fixing bolt 8. Projected along the coaxial direction of the mounting hole 1011 and the corresponding mounting slot, the guide block 103 is at least partially located between the two fixing bolts 8.
[0058] In this embodiment, the guide block 103 originally designed on the back of the steering column body 1 would obstruct the mounting hole 1011 of the ignition lock 2. To meet the installation requirements of the ignition lock 2, the traditional method would move the guide block 103 downward. However, this would also cause the rotation axis to move downward. To avoid this, the design team innovatively positioned the guide block 103 at least partially between the two fixing bolts 8 (i.e., the guide block 103 is designed to have unequal widths). This design not only meets the requirements of the assembly tool 10 for assembling the ignition lock 2, but also ensures that the position of the rotation axis will not be changed by the downward movement of the guide block 103. On the receiving bracket 101, the guide block 103 is cleverly designed between the two mounting holes 1011 (i.e., the mounting points of the ignition lock 2). When the fixing bolt 8 passes through the mounting hole 1011 and is coaxially fixed to the mounting slot of the ignition lock 2, the position of the guide block 103 provides assembly space for the installation of the ignition lock 2. The non-uniform width guide block 103 solves the problem of the guide block 103 blocking the installation point of the ignition lock 2 , thereby improving the installation flexibility.
[0059] In combination with the first aspect, in one embodiment, Figure 7 、 Figure 8 、 Figure 10 and Figure 11 As shown, the guide block 103 includes a block 1031 and a block 2 1032 fixed to the bottom end of the block 1031, projected along the mounting hole 1011 and the corresponding mounting groove in the same axis direction, the block 1031 is located between the two fixing bolts 8, the guide block 103 is provided with a guide strip hole 10311, and the block 2 1032 is provided with a guide strip hole 2 10321 arranged parallel to the guide strip hole 10311; the steering column assembly also includes: a steering column frame 9, a rotating shaft 11 is fixed between opposite sides of the steering column frame 9, the block 1031 is sleeved on the outer wall of the rotating shaft 11 through the guide strip hole 10311, arc grooves 901 are provided on opposite sides of the steering column frame 9, a swing shaft 12 is arranged between the two arc grooves 901, and the block 2 1032 is sleeved on the outer wall of the swing shaft 12 through the guide strip hole 2 10321.
[0060] In this embodiment, the guide block 103 is innovatively designed as a split structure, including block 1031 and block 2 1032 fixed to the bottom end of block 1031. This design allows the guide block 103 to more flexibly adapt to different installation requirements and space limitations. Block 1 1031 and block 2 1032 are respectively provided with guide bar hole 1 10311 and guide bar hole 2 10321, and these two guide bar holes are arranged in parallel. This design not only provides accurate positioning for the rotating shaft 11 and the swinging shaft 12, but also ensures the stability and smoothness of the guide block 103 during the sliding process. The rotating shaft 11 is fixed between the opposite sides of the steering column frame 9, and the swinging shaft 12 is provided between the two arc-shaped grooves 901. This design enables the steering column assembly to achieve both rotational and swinging motion modes, thereby improving the flexibility and accuracy of steering. Block 1031 is mounted on the outer wall of the rotating shaft 11 through guide bar hole 10311, while block 2 1032 is mounted on the outer wall of the swing shaft 12 through guide bar hole 2 10321. This coordination ensures that the guide block 103 can move accurately and smoothly with the movement of the rotating shaft 11 and the swing shaft 12. The split design of the guide block 103 and the setting of the guide bar holes enable the steering column assembly to more flexibly adapt to different spatial and positional requirements during installation, thereby improving the flexibility and convenience of installation. Through the coordination of guide bar hole 10311 and guide bar hole 2 10321 with the rotating shaft 11 and the swing shaft 12, the guide block 103 can maintain a high degree of stability and smoothness during the sliding process, avoiding failure or damage caused by shaking or offset. The setting of the rotating shaft 11 and the swing shaft 12 enables the steering column assembly to achieve both rotational and swinging motions, greatly improving the flexibility and accuracy of steering. This design not only enhances the driver's control experience but also strengthens the vehicle's stability in complex road conditions. The split design of the guide block 103 and the rational layout of the rotating shaft 11 and the swinging shaft 12 make the steering column assembly's space utilization more efficient and rational. This design not only reduces the volume and weight of the steering column assembly, but also improves the lightweighting of the entire vehicle.
[0061] Further, such as Figure 8 As shown, the opposite sides of block 1031 can be set in contact with the opposite sides of the steering column frame 9 through the contact block, further ensuring that the guide block 103 can move accurately and smoothly with the movement of the rotating shaft 11 and the swing shaft 12.
[0062] In combination with the first aspect, in one embodiment, Figure 10 and Figure 11As shown, the steering column assembly also includes: a locking mechanism 14, which is connected to one end of the swing shaft 12. The locking mechanism 14 can provide a clamping force along the axial direction of the swing shaft 12, so that the opposite sides of the steering column frame 9 are pressed against the block 2 1032, thereby limiting the movement of the block 2 1032.
[0063] In this embodiment, the locking mechanism 14 is cleverly connected to one end of the swing shaft 12. Its main function is to provide a clamping force along the axial direction of the swing shaft 12, so that the opposite sides of the steering column frame 9 can be tightly pressed on the block 2 1032. The clamping force provided by the locking mechanism 14 not only ensures the tight connection between the steering column frame 9 and the block 2 1032, but also limits the movement of the block 2 1032 through physical constraints. This design effectively prevents the block 2 1032 from being displaced or shaken under uncontrolled conditions, thereby improving the stability and reliability of the steering column assembly. By integrating the locking mechanism 14 into the swing shaft 12, the design team successfully simplified the structure of the steering column assembly. This design not only reduces the number of parts and reduces manufacturing costs, but also makes the overall layout of the steering column assembly more compact and reasonable.
[0064] In combination with the first aspect, in one embodiment, Figure 10 、 Figure 11 、 Figure 12 and Figure 13 As shown, the locking mechanism 14 includes: a cam 1401, which is coaxially fixed to the outer wall of one end of the swing shaft 12, and the cam 1401 is fixed with a handle 1402; a cam 2 1403, which is coaxially sleeved on the outer wall of one end of the swing shaft 12, and the cam 2 1403 is at least partially arranged in the arc groove 901, and the sides of the cam 1 1401 and the cam 2 1403 facing each other are both provided with helical teeth.
[0065] In this embodiment, cam 1 1401 is coaxially fixed to the outer wall of one end of the swing shaft 12. This design ensures that cam 1 1401 can swing synchronously with the swing of the swing shaft 12, thereby achieving precise control of the locking mechanism 14. Cam 2 1403 is coaxially sleeved on the outer wall of one end of the swing shaft 12 and is at least partially disposed in the arc groove 901. This design allows cam 2 1403 to rotate freely in the arc groove 901 while being constrained by the arc groove 901, ensuring its stability and accuracy during rotation. The sides of cam 1 1401 and cam 2 1403 facing each other are both provided with bevel teeth. This design allows cam 1 1401 and cam 2 1403 to engage with each other during rotation, generating a locking force or unlocking force through the interaction of the bevel teeth. The handle 1402 is fixed to cam 1 1401. This design allows the user to conveniently rotate cam 1 1401 by operating handle 1402, thereby controlling the locking and unlocking states of the locking mechanism 14. The coaxial fixation of cam 1 1401 and the swing shaft 12 and the coaxial sleeve arrangement of cam 2 1403 ensure that the locking mechanism 14 can accurately control the locking and unlocking states as the swing shaft 12 rotates. This design improves the reliability and stability of the steering column assembly. The setting of the helical teeth on cam 1 1401 and cam 2 1403 allows them to engage with each other during rotation, generating a highly efficient locking force or unlocking force. This design ensures that the locking mechanism 14 can quickly and accurately achieve the locking and unlocking functions.

The curved mounting platform is positioned within the curved groove 901. This arrangement not only limits the axial movement of cam 2 1403 but also, through the restraining effect of the curved groove 901, ensures the stability and accuracy of cam 2 1403 during rotation. The design of the rectangular mounting platform 14011 and the curved mounting platform, as well as their coordination with the handle 1402 and the curved groove 901, enhance the installation stability of the locking mechanism 14. This design ensures that the locking mechanism 14 will not loosen or fall off due to vibration or impact during long-term use.
[0068] Furthermore, assembly nut 1404 is pressed against handle 1402. Assembly nut 1404 is designed to compress handle 1402. This design ensures a secure connection between handle 1402 and cam 1 1401, preventing handle 1402 from loosening or falling off due to vibration or impact during use. Assembly nut 1404 is mounted on rectangular mounting platform 14011 and pressed against handle 1402. This design allows assembly nut 1404 to directly apply a compressive force to handle 1402, thereby enhancing the stability of the connection.
