A steering column mounting structure, a steering column assembly, and a vehicle

Abstract

This utility model discloses a steering column mounting structure, a steering column assembly, and a vehicle. It includes a mounting bracket with a body mounting portion and a steering column mounting portion, the mounting surfaces of which are parallel. The body mounting portion is connected to the body; the steering column mounting portion is connected to the steering column. When the body is subjected to external vibration, the mounting bracket forms a torsional structure to absorb the vibration. In this embodiment, the mounting bracket torsions under vibration, forming a torsional structure. Due to the mounting bracket's torsional stiffness, its modal frequency is relatively high. The excitation energy frequency generated when the body is subjected to external vibration is typically low, and the excitation energy can only effectively excite modes with frequencies close to or the same as its own. The higher modal frequency of the mounting bracket helps reduce the transmission efficiency of external vibration energy, thus reducing the vibration transmitted from the body to the steering wheel.

Utility Model Content

[0003] This utility model provides a steering column mounting structure, which aims to at least solve the problem in the prior art where vibrations transmitted to the vehicle body are transmitted to the steering wheel and perceived by the driver, thus causing customer complaints.

[0004] In a first aspect, embodiments of this utility model provide a steering column mounting structure, including: The mounting bracket is provided with a body mounting part and a steering column mounting part, the mounting surfaces of the body mounting part and the steering column mounting part are parallel to each other; the body mounting part is connected to the body; the steering column mounting part is connected to the steering column. When the vehicle body is subjected to external vibration, the mounting bracket forms a torsional structure to absorb the vibration.

[0005] Optionally, the vehicle body mounting portion includes: The mounting bracket has a first body mounting hole, a second body mounting hole, a third body mounting hole, and a fourth body mounting hole located at the four corners. The first body mounting hole, the second body mounting hole, the third body mounting hole, and the fourth body mounting hole are all connected to the vehicle body.

[0006] Optionally, the first body mounting hole and the second body mounting hole are located on one side of the mounting bracket, and the third body mounting hole and the fourth body mounting hole are located on the other side of the mounting bracket, wherein the distance between the first body mounting hole and the second body mounting hole is greater than the distance between the third body mounting hole and the fourth body mounting hole.

[0007] Optionally, one end of the steering column is a steering wheel mounting end, and the side of the mounting bracket near the steering wheel mounting end is a U-shaped crossbeam, with the first body mounting hole and the second body mounting hole located at both ends of the U-shaped crossbeam.

At this time, the mounting bracket is twisted under the action of vibration, forming a torsional structure. Since the mounting bracket has a certain torsional stiffness, the modal frequency of the mounting bracket is relatively high. However, the excitation energy frequency generated when the vehicle body is subjected to external vibration is usually low, and the excitation energy can only effectively excite modes with frequencies close to or the same as its frequency. The higher modal frequency of the mounting bracket helps to reduce the transmission efficiency of external vibration energy and reduce the vibration transmitted from the vehicle body to the steering wheel. In addition, the deformation of the mounting bracket during the torsion process can absorb some vibration energy, reduce the vibration amplitude transmitted from the mounting bracket to the steering column, and thus weaken the driver's perception of vibration at the steering wheel.

Detailed Implementation

[0019] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0020] Currently, because the steering system is connected to the vehicle body, vibrations transmitted to the vehicle body can be transmitted to the steering wheel and perceived by the driver, leading to customer complaints. To address this issue, this utility model provides a steering column mounting structure.

[0021] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0022] In a first aspect, this utility model discloses a steering column mounting structure, referring to... Figure 1 and Figure 2 As shown, it includes a mounting bracket 1, on which a body mounting part 11 and a steering column mounting part 12 are provided. The mounting surfaces of the body mounting part 11 and the steering column mounting part 12 are parallel to each other. The body mounting part 11 is connected to the body. The steering column mounting part 12 is connected to the steering column 2. When the vehicle body is subjected to external vibration, the mounting bracket 1 forms a torsional structure to absorb the vibration.

[0023] When the vehicle body is subjected to external vibration, the vibration is transmitted from the vehicle body to the mounting bracket 1 because the mounting bracket 1 is connected to the vehicle body. At this time, the mounting bracket 1 is twisted under the action of vibration, forming a torsional structure. Since the mounting bracket 1 has a certain torsional stiffness, the modal frequency of the mounting bracket 1 is relatively high. However, the excitation energy frequency generated when the vehicle body is subjected to external vibration is usually low, and the excitation energy can only effectively excite modes with a frequency close to or the same as its frequency. The higher modal frequency of the mounting bracket 1 helps to reduce the transmission efficiency of external vibration energy and reduce the vibration transmitted from the vehicle body to the steering wheel. In addition, the deformation of the mounting bracket 1 during the torsion process can absorb some vibration energy, reduce the vibration amplitude transmitted from the mounting bracket 1 to the steering column 2, and thus reduce the driver's perception of vibration at the steering wheel.

[0024] The automotive steering system is a crucial device for ensuring vehicle directional control, primarily composed of the steering column 2, steering gear, steering transmission mechanism, and column mounting bracket 1. The steering column 2 connects the steering wheel and steering gear, transmitting the driver's steering commands. The steering gear converts the rotational motion of the steering wheel into wheel deflection motion, amplifying power and changing direction through mechanisms such as racks and pinions or worm gears. The steering transmission mechanism transmits the force output from the steering gear to the wheels, achieving wheel deflection. The steering column 2 is typically mounted to the vehicle body via the column mounting bracket 1. When the driver turns the steering wheel, the steering column 2 transmits this rotational motion to the steering gear. The rack and pinion or worm gear mechanism inside the steering gear converts the rotational motion of the steering wheel into linear motion, amplifies the power, and changes the direction of motion, making the steering force transmission more efficient. The steering transmission mechanism then transmits the force output from the steering gear to the wheels, causing the wheels to deflect, thus achieving vehicle steering.

[0025] Modal frequencies are the natural frequencies of a structure during free vibration. They reflect the vibration characteristics of a structure in a specific mode. External excitation refers to external forces, torques, or other forms of input energy acting on a system, which triggers a system response. When the external excitation frequency approaches the modal frequency of the structure, resonance occurs. Resonance leads to a sharp increase in the vibration amplitude of the structure, potentially causing fatigue damage or even destruction. In mechanical systems, if the operating frequency of a motor is close to the modal frequency of the equipment, it can also cause resonance, affecting the normal operation of the equipment. When the excitation frequency is close to the modal frequency, the vibration is amplified, which may lead to excessive vibration of the structure. Conversely, when the excitation frequency is far from the modal frequency, the vibration is attenuated, and the vibration response of the structure is smaller. The transmission path of vibration in a structure is affected by the modal frequency. In multi-degree-of-freedom systems, vibration will be transmitted along the path with the lower modal frequency.

[0026] In a preferred embodiment, refer to Figure 1 and Figure 3 The mounting bracket 1 has a rectangular overall outline. The four vertices of the rectangular mounting bracket 1 extend away from the center of the rectangle, forming the four corners of the mounting bracket 1. The vehicle body mounting part 11 includes: The first body mounting hole 111, the second body mounting hole 112, the third body mounting hole 113, and the fourth body mounting hole 114 are provided at the four corners of the mounting bracket 1. The first body mounting hole 111, the second body mounting hole 112, the third body mounting hole 113, and the fourth body mounting hole 114 are connected to the body.

[0027] Since the first body mounting hole 111, the second body mounting hole 112, the third body mounting hole 113 and the fourth body mounting hole 114 are located at the four corners of the mounting bracket 1, the distance between the mounting bracket 1 and the different connection positions of the body is increased. When vibration is transmitted from the body to the mounting bracket 1, the greater distance between the connection positions provides the mounting bracket 1 with a larger deformation space, so that more vibration energy can be absorbed during the deformation process, and the vibration amplitude transmitted from the mounting bracket 1 to the steering column 2 is further reduced.

[0028] In a preferred embodiment, refer to Figure 1 and Figure 2 The first body mounting hole 111 and the second body mounting hole 112 are located on one side of the mounting bracket 1, and the third body mounting hole 113 and the fourth body mounting hole 114 are located on the other side of the mounting bracket 1. The distance between the first body mounting hole 111 and the second body mounting hole 112 is greater than the distance between the third body mounting hole 113 and the fourth body mounting hole 114.

[0029] Because the distance between the first body mounting hole 111 and the second body mounting hole 112 is greater than the distance between the third body mounting hole 113 and the fourth body mounting hole 114, the stiffness of the two ends of the mounting bracket 1 is different. The different stiffness leads to different modal frequencies at different positions. External excitation needs to match multiple different frequencies at the same time to induce resonance. The different mounting distance reduces the probability of the mounting bracket 1 resonating, thereby reducing the probability of external vibration being transmitted to the steering wheel through the mounting bracket 1.

[0030] In a preferred embodiment, refer to Figure 1 and Figure 2 One end of the steering column 2 is the steering wheel mounting end 21, and the side of the mounting bracket 1 near the steering wheel mounting end 21 is a U-shaped crossbeam 13. The first body mounting hole 111 and the second body mounting hole 112 are located at both ends of the U-shaped crossbeam 13.

[0031] The bottom end 131 of the U-shaped crossbeam 13 is arc-shaped, and the open end 132 of the U-shaped crossbeam 13 is located at the two vertices on one side of the mounting bracket 1. After the steering wheel is installed at the steering wheel mounting end 21, since the first body mounting hole 111 and the second body mounting hole 112 are located at the two ends of the open end 132 of the U-shaped crossbeam 13 respectively, and the U-shaped crossbeam 13 is located at the end of the mounting bracket 1 close to the steering wheel mounting point, the distance from the steering wheel to the connection position between the mounting bracket 1 and the body is shortened to a certain extent. That is, the length of the upper cantilever beam of the steering wheel is shortened, the mode of the upper cantilever beam of the steering wheel is improved, and the amount of external vibration transmitted to the steering wheel through the upper cantilever beam of the steering wheel is reduced.

[0032] In a preferred embodiment, refer to Figure 1 and Figure 2 The mounting bracket 1 is frame-shaped overall. A U-shaped crossbeam 13 forms one side of the frame, and the other side of the mounting bracket 1 furthest from the U-shaped crossbeam 13 is a structural crossbeam. The U-shaped crossbeam 13 and the structural crossbeam are defined as the top and bottom edges of the mounting bracket 1, respectively. The third body mounting hole 113 and the fourth body mounting hole 114 penetrate the other two sides of the mounting bracket 1. By designing the mounting bracket 1 as a frame, its weight is reduced, increasing its natural frequency and thus improving the system modes and reducing vibration transmission. Furthermore, reducing the weight of the mounting bracket 1 helps to reduce the risk of injury. This reduces the difficulty of manual or mechanical assembly and improves assembly efficiency. Simultaneously, a reinforcing beam 17 is installed within the frame. According to the basic formula of modal analysis, the natural frequency of the system is directly proportional to the square root of the stiffness and inversely proportional to the square root of the mass. By setting up the reinforcing beam 17, the force generated during vibration is more evenly distributed throughout the entire mounting bracket 1, making the stress distribution more uniform, reducing local high-stress areas, thereby improving the overall stiffness and durability of the mounting bracket 1. While reducing the weight of the mounting bracket 1, the stiffness of the mounting bracket 1 is increased, reducing the risk of system modal degradation due to decreased stiffness.

[0033] In a preferred embodiment, refer to Figure 1 and Figure 2 The steering column mounting section 12 includes a plurality of column mounting holes 121; The mounting bracket 1 is along the axial direction of the steering column 2, and one side of the steering column 2 has a flange 14 corresponding to the column mounting hole 121, wherein the column mounting hole 121 is located on the flange 14.

[0034] In this embodiment of the invention, the steering column 2 has four flanges 14, which together form a rectangular area. A column mounting hole 121 passes through the flanges 14. When installing the steering column 2, it is placed on the side of the mounting bracket 1 furthest from the vehicle body. Then, the steering column 2 is connected to the mounting bracket 1 through the column mounting hole 121, completing the installation of the steering column 2. Since the flanges 14 are formed by folding the mounting bracket 1, and are integrally molded with the mounting bracket 1, the connection stability between the steering column 2 and the column bracket is enhanced.

[0035] In this embodiment of the utility model, when the mounting bracket 1 is connected to the steering column 2, the mounting bolt 18 is provided and passed through the column mounting hole 121 to connect with the steering column 2. When the steering column 2 needs to be inspected and maintained, the steering column 2 can be disassembled by removing the mounting bolt 18, which facilitates the work of the operator.

[0036] Another steering column mounting structure of this utility model may include multiple column welding points, which enclose a rectangular area, and four column welding points are located at the vertices of the rectangular area. When the mounting bracket 1 is connected to the steering column 2, the steering column 2 and the mounting bracket 1 can be directly connected at the column welding points by welding. At this time, the connection stability between the steering column 2 and the column bracket is further enhanced, and the structure of the mounting bracket 1 is simplified, and the production process of the mounting bracket 1 is simplified.

[0037] In a preferred embodiment, refer to Figure 1 and Figure 2 The steering column 2 abuts against the flange 14, and the axis of the steering column 2 is parallel to the plane where the flange 14 is located.

[0038] After the steering column 2 is connected to the mounting bracket 1, the flange 14 abuts against the steering column 2, allowing the steering column 2 to connect to the column bracket through the column mounting hole 121. At the same time, the column bracket forms an interference fit. The interference fit increases the contact pressure between the steering column 2 and the column bracket, thereby improving the connection strength and stability between the steering column 2 and the column bracket. Furthermore, since the interference fit can increase the friction of the connection surface, it can effectively prevent the steering column 2 and the column bracket from loosening during use. Even under high load or impact load, it can remain stable, further enhancing the connection stability between the steering column 2 and the column bracket.

[0039] In a preferred embodiment, refer to Figure 1 and Figure 2The mounting bracket 1 has two weight-reduction grooves 15 on its surface, located on both sides of the steering column 2. The weight-reduction grooves 15 are on the same plane as the first body mounting hole 111 and the second body mounting hole 112. The design of the weight-reduction grooves 15 can reduce the weight of the mounting bracket 1 and improve the system mode; at the same time, by removing material in some areas, the weight-reduction grooves 15 can significantly reduce raw material consumption and reduce production costs.

[0040] In a preferred embodiment, refer to Figure 1 and Figure 4 The mounting bracket 1 has reinforcing ribs 16 on its surface, and the reinforcing ribs 16 extend parallel to the mounting surface of the steering column mounting part 12. By providing reinforcing ribs 16 on the surface of the mounting bracket 1, the rigidity of the mounting bracket 1 is increased, the modal frequency of the mounting bracket 1 is further increased, and the vibration transmitted from the vehicle body to the steering wheel is reduced.

[0041] In this embodiment of the invention, the mounting bracket 1 has two support plates 19 folded away from the vehicle body on both sides. The plane of the support plates 19 is parallel to the plane of the flange 14. The steering column 2 is located between the two support plates 19, and the opposite side of the two support plates 19 abuts against the steering column 2 to clamp it. The clamping of the column bracket by the support plates 19 further enhances the connection stability between the steering column 2 and the column bracket. The reinforcing rib 16 is located on the side of the support plate 19 away from the steering column 2. When the steering column 2 is connected to the mounting bracket 1, the steering column 2 exerts a certain force on the support plate 19. The reinforcing rib 16 can enhance the strength of the support plate 19 and reduce the risk of deformation of the support plate 19 under the action of the steering column 2.

[0042] In this embodiment of the present invention, when the vehicle body is subjected to external vibration, since the mounting bracket 1 is connected to the vehicle body, the vibration is transmitted from the vehicle body to the mounting bracket 1. At this time, the mounting bracket 1 is twisted under the action of vibration, forming a torsional structure. Since the mounting bracket 1 has a certain torsional stiffness, the modal frequency of the mounting bracket 1 is relatively high. However, the excitation energy frequency generated when the vehicle body is subjected to external vibration is usually low, and the excitation energy can only effectively excite modes with frequencies close to or the same as its frequency. The higher modal frequency of the mounting bracket 1 helps to reduce the transmission efficiency of external vibration energy and reduce the vibration transmitted from the vehicle body to the steering wheel. In addition, the mounting bracket 1 deforms during the torsion process, which can absorb some vibration energy and reduce the vibration amplitude transmitted from the mounting bracket 1 to the steering column 2, thereby weakening the driver's perception of vibration at the steering wheel.

[0043] Secondly, this utility model also discloses a steering column 2 assembly, including a steering column 2 and the aforementioned steering column mounting structure; the steering column 2 is connected to the vehicle body via the steering column mounting structure. The steering column mounting structure includes a mounting bracket 1, on which a vehicle body mounting part 11 and a steering column mounting part 12 are provided, the mounting surfaces of the vehicle body mounting part 11 and the steering column mounting part 12 being perpendicular to each other; the vehicle body mounting part 11 is connected to the vehicle body; the steering column mounting part 12 is connected to the steering column 2; when the vehicle body is subjected to external vibration, the mounting bracket 1 forms a torsional structure to resist the vibration.

[0044] Since the steering column 2 assembly includes the aforementioned steering column mounting structure, it also possesses the beneficial effects of the aforementioned steering column mounting structure, which will not be elaborated here.

[0045] Thirdly, this utility model embodiment also discloses a vehicle including the aforementioned steering column mounting structure. The steering column mounting structure includes a mounting bracket 1, on which a body mounting portion 11 and a steering column mounting portion 12 are provided. The mounting surfaces of the body mounting portion 11 and the steering column mounting portion 12 are perpendicular to each other. The body mounting portion 11 is connected to the body; the steering column mounting portion 12 is connected to the steering column 2. When the body is subjected to external vibration, the mounting bracket 1 forms a torsional structure to resist the vibration.

[0046] Since the vehicle includes the aforementioned steering column mounting structure, it also possesses the beneficial effects of the aforementioned steering column mounting structure, which will not be elaborated upon here.
