Description

Technical Field

[0001] The utility model relates to a field, in particular to a steering column assembly and a vehicle. Background Art

[0002] In the automotive industry, the steering column is an important part of the vehicle's steering system, responsible for connecting the driver's steering wheel and the vehicle's steering mechanism, allowing the driver to control the vehicle's direction through the steering wheel. In order to improve the vehicle's handling and ride comfort, non-angle-adjustable steering columns often require special design and optimization.

[0003] At present, in order to improve the performance of the steering column, the industry usually adds a shock-absorbing bushing in the hole of the column mounting bracket to increase understeer or improve NVH (noise, vibration and irritation) performance. The shock-absorbing bushing can effectively absorb and isolate vibration and noise from the road, improving the driver's driving experience and the passenger's riding comfort.

[0004] For example, CN207931795U proposes a steering column and a bushing, which achieves a zero-gap and tight fit between the three by adding a bushing between the inner sleeve and the outer sleeve. On the one hand, it reduces the difficulty of processing the matching dimensions of the inner sleeve and the outer sleeve and the surface treatment process level. On the other hand, it can eliminate the vibration and abnormal noise of the steering column under harsh working conditions such as bumpy roads, thereby reducing driver complaints.

[0005] However, the existing technical solutions do not fully consider the harsh environment that the vehicle may encounter during actual driving and the violent operation of the steering wheel by the driver. When driving at high speed, on bumpy roads or in emergency situations, the vehicle may be subjected to large vibrations and impacts. At the same time, the driver may turn the steering wheel vigorously in an emergency. These external factors may cause the shock absorbing bushing to come out of the mounting hole, thereby affecting the performance of the steering column and the safety of the entire vehicle.

[0033] 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.

[0034] In the related art, the existing technical solutions do not fully consider the harsh environment that the vehicle may encounter during actual driving and the violent operation of the steering wheel by the driver. When driving at high speed, on bumpy roads or in emergency situations, the vehicle may be subjected to large vibrations and impacts. At the same time, the driver may turn the steering wheel vigorously in an emergency. These external factors may cause the shock absorbing bushing to come out of the mounting hole, thereby affecting the performance of the steering column and the safety of the entire vehicle.

[0035] Reference below Figure 1-Figure 6 A steering column assembly 1 according to an embodiment of the present invention is described.

[0036] like Figure 1-Figure 3 As shown, according to the utility model, the steering column assembly 1 includes a steering column 11, a bushing body 12 and a limiter 13. The steering column 11 is provided with a mounting hole. The bushing body 12 is installed in the mounting hole of the steering column 11. A limiter 121 is formed at one end of the bushing body 12. The limiter 121 abuts against one end of the steering column 11 to limit the bushing body 12 from coming out of the other end of the mounting hole. The limiter 13 is cooperatively connected with the other end of the bushing body 12 and abuts against the other end of the steering column 11 to limit the bushing body 12 from coming out of one end of the mounting hole.

[0037] The steering column assembly 1 of the present application realizes the functions of shock absorption and buffering by installing the bushing body 12 in the mounting hole of the steering column 11, and effectively improves the stability and durability of the steering system. By setting a limiter 121 at one end of the bushing body 12, the limiter 121 can stop against one end of the steering column 11, thereby limiting the bushing body 12 from coming out from the other end of the mounting hole. By setting a limiter 13, the limiter 13 can be matched and connected with the bushing body 12, and the limiter 13 can stop against the other end of the steering column 11, thereby limiting the bushing body 12 from coming out from one end of the mounting hole. The limiting of the bushing body 12 by the limiter 121 and the limiter 13 improves the stability and reliability of the steering column 11 assembly during operation, reduces the safety hazards caused by the bushing body 12 coming out, especially in high-speed driving, bumpy roads or emergency situations, can significantly reduce the impact of vibration and impact force on the steering system, so that the driver can accurately and stably control the driving direction of the vehicle.

[0038] Therefore, the steering column assembly 1 of the present application limits the bushing body 12 by the limiting portion 121 and the limiting member 13, thereby reducing the safety hazard caused by the bushing body 12 falling out of the mounting hole, significantly enhancing the stability and reliability in harsh environments and under intense driver operation, and enabling the driver to accurately and stably control the driving direction of the vehicle.

[0039] According to some embodiments of the present invention, Figure 2-Figure 4 , Figure 6As shown, the stopper 13 is formed with a first matching groove 13a which is open toward one end of the bushing body 12, and the other end of the bushing body 12 extends into the first matching groove 13a and is limitedly matched with at least part of the wall surface of the first matching groove 13a. By providing the first matching groove 13a which is open toward one end of the bushing body 12 on the stopper 13, and by extending the other end of the bushing body 12 into the first matching groove 13a and forming a limited match with the wall surface of the first matching groove 13a, the bushing body 12 can be firmly fixed on the steering column 11 after installation, and the shaking and displacement of the bushing body 12 during use can be reduced, thereby improving the stability and reliability of the steering system, and can facilitate the installation of the bushing body 12, simplifying the installation process.

[0040] According to some embodiments of the utility model, an internal thread is formed on the inner peripheral wall of the first matching groove 13a, and an external thread is formed on the outer peripheral wall of the other end of the bushing body 12, and the internal thread and the external thread cooperate to extend the other end of the bushing body 12 into and fix it in the first matching groove 13a. By providing an internal thread on the inner peripheral wall of the first matching groove 13a, and providing an external thread on the outer peripheral wall of the other end of the bushing body 12, the internal thread and the external thread can cooperate with each other, so that the other end of the bushing body 12 is extended into and firmly fixed in the first matching groove 13a. Specifically, when installing the bushing body 12, it is only necessary to align the external thread portion of the bushing body 12 with the internal thread portion of the first matching groove 13a, and rotate the bushing body 12 so that the bushing body 12 gradually extends into the first matching groove 13a. As the rotation proceeds, the external thread and the internal thread bite each other to form a tight threaded connection, so that the bushing body 12 is firmly fixed on the steering column 11.

[0041] According to some embodiments of the utility model, the outer edge of the limiter 13 is formed with a clamping portion extending radially outward. By providing the clamping portion, the clamping portion extends radially outward, so that the limiter 13 is easier to install and remove. During the installation process, the clamping portion can be used to clamp and rotate with appropriate tools, so that the limiter 13 can be easily installed to the desired position. Similarly, during disassembly, the clamping portion can also be used to perform a convenient disassembly operation, which not only improves work efficiency, but also helps to reduce errors or damage that may occur during installation and disassembly.

[0042] According to some embodiments of the present invention, Figure 1 , Figure 3 and Figure 6As shown, the steering column 11 includes a bracket 111, a mounting hole is provided on the bracket 111, and a protrusion 111a extending toward the other end of the bushing body 12 is provided on the bracket 111; wherein the stopper 13 forms a second matching groove 13b open toward one end of the bushing body 12, the second matching groove 13b is sleeved on the outer periphery of the protrusion 111a, and the bottom wall of the second matching groove 13b abuts against the end of the protrusion 111a. The steering column 11 includes a bracket 111, and a mounting hole is provided on the bracket 111 for installing the bushing body 12. By providing the protrusion 111a extending toward the other end of the bushing body 12 on the bracket 111, the protrusion 111a provides a stable support for the installation of the stopper 13. By providing a second matching groove 13b open toward one end of the bushing body 12 on the limit member 13, the second matching groove 13b can be sleeved on the outer periphery of the protrusion 111a so that the bottom wall of the second matching groove 13b abuts against the end of the protrusion 111a. When the limit member 13 is subjected to external impact or vibration, it can effectively limit the displacement of the bushing body 12, thereby improving the stability and reliability of the steering system.

[0043] According to some embodiments of the present invention, Figure 6 As shown, the stopper 13 includes a base plate 131, a first ring portion 132 and a second ring portion 133. The base plate 131 is provided with a through hole corresponding to the mounting hole; the first ring portion 132 is provided on the base plate 131 and defines a first matching groove 13a with the base plate 131; the second ring portion 133 is provided on the outer periphery of the base plate 131, and the inner peripheral wall of the second ring portion 133 defines a second matching groove 13b with the outer peripheral walls of the base plate 131 and the first ring portion 132 respectively. The base plate 131 serves as the base part of the stopper 13, and the base plate 131 is provided with a through hole corresponding to the mounting hole of the steering column 11. In this way, when the stopper 13 is installed on the steering column 11, the through hole is aligned with the mounting hole, and the fastener can be easily extended from the through hole without being hindered by the stopper 13. By arranging the first ring portion 132 on the bottom plate 131, the first ring portion 132 and the bottom plate 131 jointly define a first matching groove 13a, and the first matching groove 13a is used to match with the other end of the bushing body 12, and the displacement of the bushing body 12 is limited by the limit matching method, thereby improving the stability of the steering system. By arranging the second ring portion 133 on the periphery of the bottom plate 131, the inner peripheral wall of the second ring portion 133 and the outer peripheral wall of the bottom plate 131 and the first ring portion 132 respectively define a second matching groove 13b, and the second matching groove 13b can match with the protrusion 111a on the steering column 11, so that the limiter 13 can be stably installed on the steering column 11. At the same time, the bottom wall of the second matching groove 13b stops against the end of the protrusion 111a, further enhancing the connection stability and reliability of the limiter 13 and the steering column 11.

[0044] According to some embodiments of the present invention, Figure 3and Figure 5 As shown, the steering column 11 also includes a first flexible member 112, which is arranged between the protrusion 111a and the stopper 13, and at least part of the first flexible member 112 is accommodated in the second matching groove 13b. By arranging the first flexible member 112, the shock absorption and buffering capacity of the steering system is improved. Specifically, the first flexible member 112 is arranged between the protrusion 111a and the stopper 13, and at least part of it is accommodated in the second matching groove 13b, so that the first flexible member 112 can play a buffering role between the protrusion 111a and the stopper 13. When the steering system is impacted or vibrated by external forces, the first flexible member 112 can effectively absorb and disperse these forces, reduce the direct impact on the steering column 11 and the stopper 13, thereby protecting the stability and reliability of the steering system. At the same time, the arrangement of the first flexible member 112 can also reduce the friction and wear between the steering column 11 and the stopper 13 to a certain extent, and extend the service life of the steering system.

[0045] According to some embodiments of the present invention, Figure 4 As shown, the limiting portion 121 extends radially outward at one end of the bushing body 12, and the limiting portion 121 is arranged around the outer periphery of the other end of the bushing body 12. The radial extension of the limiting portion 121 outward enables the limiting portion 121 to stop against the steering column 11, increasing the contact area between the limiting portion 121 and the steering column 11, thereby improving the fixing effect, so that the limiting portion 121 can fit more closely on the steering column 11, reducing the shaking and displacement caused by vibration or impact force. In addition, the limiting portion 121 is arranged around the outer periphery of the other end of the bushing body 12, forming a surrounding fixing effect, so that the bushing body 12 can be more evenly supported and fixed when subjected to external force, further improving the stability and reliability of the steering system.

[0046] According to some embodiments of the present invention, Figure 3 As shown, the steering column 11 also includes a second flexible member 113, which is sleeved on the outer periphery of the bushing body 12 to be arranged between the inner peripheral wall of the mounting hole and the outer peripheral wall of the bushing body 12. By arranging the second flexible member 113, the shock absorption and buffering capacity of the steering system can be further improved. Specifically, the second flexible member 113 is sleeved on the outer periphery of the bushing body 12 and is located between the inner peripheral wall of the mounting hole and the outer peripheral wall of the bushing body 12, so that the second flexible member 113 can absorb and buffer shocks and vibrations between the bushing body 12 and the steering column 11. When the steering system is subjected to external shock or vibration, the second flexible member 113 can effectively absorb and disperse these forces, reduce the direct impact on the steering column 11 and the bushing body 12, and enable the driver to obtain a more stable and comfortable driving experience during driving.

[0047] According to some embodiments of the utility model, the axial dimension of the second flexible member 113 is smaller than the axial dimension of the bushing body 12, so as to expose the other end of the bushing body 12 and cooperate with the stopper 13. The axial dimension of the second flexible member 113 is designed to be smaller than the axial dimension of the bushing body 12, so that the other end of the bushing body 12 can be exposed and cooperate with the stopper 13. The other end of the bushing body 12 will not be completely covered by the second flexible member 113, but a part will be exposed, and the exposed part of the bushing body 12 can cooperate with the stopper 13. Specifically, the exposed part of the bushing body 12 can be the external thread in the above embodiment.
