Description

Vehicle steering tube angle adjustment installation structure Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a vehicle steering tube angle adjustment and installation structure. Background Technology

[0002] In the context of the modern automotive industry's trend towards intelligent and human-centered design, steering wheels typically feature both height and fore-and-aft adjustment to accommodate the operating habits of drivers of different heights and builds, ensuring drivers can operate the steering wheel in the most comfortable posture. The height adjustment, also known as steering wheel height adjustment, is generally achieved by controlling the rotation of the steering tube relative to the vehicle body (angle adjustment). This process requires balancing structural stability with the flexibility of rotation.

[0003] However, existing vehicle steering column angle adjustment mechanisms on the market have significant drawbacks. Some traditional adjustment structures employ a non-rigid connection design to ensure the steering column's rotational freedom, thus increasing the installation clearance between components. However, excessive installation clearance can cause steering wheel wobble during vehicle operation, affecting not only the driver's experience but also extending the overall structural lifespan due to long-term wear, posing a safety hazard.

[0004] Therefore, how to achieve zero-clearance installation of the vehicle steering tube angle adjustment mechanism and ensure the stability of the overall structure has become an important research direction for improving the performance of automotive steering systems. Summary of the Invention

[0005] In view of this, the present invention provides a vehicle steering tube angle adjustment installation structure, which can ensure zero-gap installation of the mechanism and realize steering wheel angle adjustment.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A vehicle steering tube angle adjustment installation structure, the key features of which are: a base, a linkage component and a sliding block, wherein the base is used to connect the vehicle steering tube, and both the base and the linkage component are used to be rotatably mounted on the vehicle, and a power drive component is provided between the base and the linkage component, the power drive component being used to drive the linkage component to rotate relative to the vehicle.

[0008] The base has a mounting groove extending along its length on its side. The sliding block can be slidably installed in the mounting groove. The sliding block is rotatably connected to the linkage component through a rotating shaft. When the linkage component rotates relative to the vehicle, the sliding block can drive the base to rotate relative to the vehicle.

[0009] An elastic component abuts against the side wall of the mounting groove, allowing the sliding block to be installed between the base and the linkage component with zero clearance.

[0010] With the above structure, in application, the steering tube A1 of the vehicle steering system is fixedly mounted in the base, and the steering wheel A2 is installed at the front end of the steering tube A1. The power drive assembly drives the linkage component to rotate relative to the vehicle. Under the connecting transmission action of the sliding block, the base can be driven to rotate up and down relative to the vehicle, which in turn drives the steering tube A1 to rotate up and down relative to the vehicle, thereby realizing the height adjustment of the steering wheel A2. By setting the sliding block and the elastic component in the mounting groove, the elastic component can absorb the gap of the sliding block in the vertical direction of the installation. Even during the relative movement of the sliding block, it can ensure that the base and the linkage component always maintain a tight connection, thereby achieving zero-gap installation between the base and the linkage component.

[0011] Preferably, the mounting groove is constructed as a trapezoidal groove structure with two symmetrical first inclined surfaces, and the sliding block is a trapezoidal block with elastic components between its two sides and the corresponding first inclined surfaces. With this structure, the symmetrically arranged elastic components on both sides can better absorb gaps in both the vertical and horizontal directions, ensuring that the sliding block always fits tightly within the mounting groove.

[0012] Preferably, the sliding block has holes arranged in an array on its side, and the elastic component is a rubber column installed within the holes. The outer end of the rubber column protrudes outward from the side of the sliding block and abuts against the wall of the mounting groove. With this structure, the rubber column possesses high elasticity and good flexibility, effectively buffering high-frequency vibrations and impacts during vehicle operation. Simultaneously, the arrayed rubber columns provide uniform and continuous elastic support, ensuring the sliding block remains in a pre-tightened state within the mounting groove. This further enhances the tightness of the connection between the base and the linkage component, thereby achieving better zero-gap installation between the base and the linkage component.

[0013] Preferably, the sliding block has a mounting hole in the middle, and a bushing is provided inside the mounting hole. The bushing has an annular, non-closed structure with a slit on one side. This structure ensures a tight, zero-gap assembly between the sliding block and the rotating shaft after installation.

[0014] Preferably, the base has mounting grooves on both sides, and the sliding blocks on both sides are rotatably connected to the linkage component via a rotating shaft that runs through the width of the base. This structure allows for more uniform force transmission.

[0015] Preferably, the end of the rotating shaft is provided with a nut to ensure a tight connection between the linkage component and the base; the nut has a second inclined surface in its circumferential direction. This structure ensures a tight connection between the linkage component and the base, preventing loosening or relative displacement between them, thus guaranteeing the reliability and stability of the installation.

[0016] Preferably, the system also includes a linkage support base, which is used for fixed assembly inside the vehicle, and the linkage component is rotatably connected to the linkage support base. With this structure, the linkage support base provides a stable mounting reference for the vehicle steering tube angle adjustment installation structure, ensuring a stable connection between the linkage component, the base, and other components and the vehicle.

[0017] Preferably, the base has a first hinge at its rear end, and the linkage component has a second hinge at its rear end. Both the first and second hinges are rotatably connected to the vehicle. The sliding block connects the base and the front of the linkage component. With this structure, the power drive assembly drives the linkage component to rotate up and down around the second hinge. Under the connecting transmission action of the sliding block, the base is forced to rotate up and down around the first hinge 1a, thus achieving height adjustment of the steering wheel.

[0018] Preferably, the linkage component has a vertical section located on one side of the base, with an extension section extending vertically forward at the upper end of the vertical section. The second hinge portion is located at the upper end of the vertical section, and the power drive assembly is used to drive the vertical section to rotate around the second hinge portion. The sliding block is located at the front end of the extension section. With this structure, the linkage component can more effectively drive the base to rotate, offering advantages such as simple structure, good stability, and flexible rotation.

[0019] Preferably, the power drive component is a push rod motor, which includes a push rod, the end of which is rotatably connected to the lower end of the vertical section. With this structure, the push rod motor offers the technical advantages of simple and precise control and smooth operation.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The vehicle steering tube angle adjustment installation structure provided by this utility model is used in which the steering tube A1 of the vehicle steering system is fixedly assembled in the base, and the steering wheel A2 is installed at the front end of the steering tube A1. The power drive component drives the linkage component to rotate relative to the vehicle. Under the connecting transmission action of the sliding block, the base can be driven to rotate up and down relative to the vehicle, which means that the steering tube A1 is driven to rotate up and down relative to the vehicle, thereby realizing the height adjustment of the steering wheel A2.

[0022] 2. By setting sliding blocks and elastic components in the mounting groove, the elastic components can absorb the gaps of the sliding blocks in the vertical direction during installation. Even during the relative movement of the sliding blocks, the base and the linkage components can always maintain a tight connection, thereby achieving zero-gap installation between the base and the linkage components.

[0023] 3. The vehicle steering tube angle adjustment installation structure provided by this utility model, through the cooperation of trapezoidal groove, trapezoidal block and elastic component, not only takes into account zero clearance assembly, but also does not cause excessive adjustment resistance, which is a solution with excellent comprehensive performance.

[0032] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0033] Please refer to Figure 8. A vehicle steering tube angle adjustment mounting structure includes a base 1, a linkage component 2, and a sliding block 4. The base 1 is used to connect the vehicle steering tube A1. The base 1 has a front end and a rear end. In application, the rear end of the base 1 is hinged to the vehicle body A. The linkage component 2 is located at the front of the base 1 and is rotatably mounted on the vehicle body A. A power drive assembly 3 is provided between the base 1 and the linkage component 2, which can drive the linkage component 2 to rotate relative to the vehicle. As shown in Figures 2 to 4, a mounting groove 11 extending along its length is provided on the left side of the base 1. The opening of the mounting groove 11 faces the left side of the base 1. The sliding block 4 is slidably mounted in the mounting groove 11. The sliding block 4 is rotatably connected to the linkage component 2 through a rotating shaft 5. When the linkage component 2 rotates relative to the vehicle, the sliding block 4 can drive the base 1 to rotate relative to the vehicle. An elastic component a is abutting between the sliding block 4 and the side wall of the mounting groove 11. This elastic component a allows the sliding block 4 to be installed between the base 1 and the linkage component 2 with zero clearance.

[0034] Based on the above structural design, in application, the steering tube A1 of the vehicle steering system is fixedly assembled in the base 1, and the steering wheel A2 is installed at the front end of the steering tube A1. The power drive component 3 drives the linkage component 2 to rotate relative to the vehicle. Under the connecting transmission action of the sliding block 4, the base 1 can be driven to rotate up and down relative to the vehicle, which also drives the steering tube A1 to rotate up and down relative to the vehicle, thereby realizing the height adjustment of the steering wheel A2. By setting the sliding block 4 and the elastic component a in the mounting groove 11, the elastic component a can absorb the gap of the sliding block 4 in the vertical direction of installation. Even during the relative movement of the sliding block 4, it can ensure that the base 1 and the linkage component 2 always maintain a tight connection, thereby realizing zero-gap installation between the base 1 and the linkage component 2.

[0035] Referring to Figures 1 and 8, the rear end of the base 1 has a first hinge portion 1a, and the rear end of the linkage component 2 has a second hinge portion 2a. Both the first hinge portion 1a and the second hinge portion 2a are used for rotatable connection to the vehicle. The linkage component 2 is located at the front of the base 1, and a sliding block 4 connects the base 1 and the front of the linkage component 2. The power drive assembly 3 drives the linkage component 2 to rotate up and down around the second hinge portion 2a. Under the connecting transmission action of the sliding block 4, the base 1 can be forced to rotate up and down around the first hinge portion 1a, thereby realizing the height adjustment of the steering wheel. This structural design makes the rotatable connection between the base 1 and the linkage component 2 on the vehicle more stable.

[0036] Referring again to Figures 1 and 8, the vehicle steering tube angle adjustment mounting structure also includes a linkage support 6. In practical applications, the linkage support 6 is fixedly mounted on the vehicle body A by bolts, and the second hinge 2a of the linkage component 2 is rotatably connected to the linkage support 6. The linkage support 6 provides a stable mounting reference for the vehicle steering tube angle adjustment mounting structure, ensuring a stable connection between the linkage component 2, the base 1, and other components and the vehicle.

[0037] As shown in Figures 1 and 2, the specific structure of the linkage component 2 is as follows: In this embodiment, the linkage component 2 has a vertical section 21 located on the left side of the base 1. The upper end of the vertical section 21 has a vertically extending forward extension section 22. The second hinge portion 2a is located at the upper end of the vertical section 21, and the sliding block 4 is located at the front end of the extension section 22. The power drive assembly 3 drives the lower end of the vertical section 21 to swing back and forth relative to the vehicle, thus enabling the linkage component 2 to rotate as a whole around the second hinge portion 2a. The rotation of the front end of the extension section 22, under the connecting transmission action of the sliding block 4, drives the base 1 to rotate up and down around the first hinge portion 1a. Through the above structural design, the linkage component 2 can more effectively drive the base 1 to rotate, possessing the technical advantages of simple structure, good stability, and flexible rotation.

[0038] As shown in Figures 3 and 4, the mounting groove 11 is constructed as a trapezoidal groove structure with two symmetrical first inclined surfaces 111. The sliding block 4 is a trapezoidal block, and elastic components a are provided between the two sides of the trapezoidal block and the corresponding first inclined surfaces 111. Through the cooperation of the trapezoidal groove, the trapezoidal block, and the elastic components a, the symmetrically arranged elastic components a on both sides can better absorb the gaps in both the vertical and horizontal directions, ensuring that the sliding block 4 is always tightly fitted within the mounting groove 11. Compared with other structures such as rectangles, the trapezoidal block can better absorb and buffer the stress and impact generated by swinging, protecting the base 1 and the linkage component 2 from damage, and further improving the reliability and durability of the overall structure.

[0039] Furthermore, as shown in Figure 6, holes are arrayed on both sides of the sliding block 4. In this embodiment, the elastic component a is a rubber column installed in the hole. As shown in Figure 3, the outer end of the rubber column protrudes outward from the side of the sliding block 4 and abuts against the wall of the mounting groove 11. The rubber column has high elasticity and good flexibility, which can effectively buffer high-frequency vibration and impact during vehicle operation. At the same time, the arrayed rubber columns can provide uniform and continuous elastic support force, so that the sliding block 4 is always in a pre-tightened state in the mounting groove 11, which further improves the tightness of the connection between the base 1 and the linkage component 2, thereby better realizing zero-gap installation between the base 1 and the linkage component 2.

[0040] Referring to Figure 6, the sliding block 4 has a mounting hole 41 in the middle. Combined with Figures 3 and 5, a bushing 42 is provided inside the mounting hole 41, and the end of the rotating shaft 5 is rotatably supported within the bushing 42. In this embodiment, the bushing 42 is an annular, non-closed structure, and a slit 421 is formed on one side of the bushing 42. This design ensures that after installation, the sliding block 4 and the rotating shaft 5 are tightly assembled with zero clearance, preventing loosening and gaps between the rotating shaft 5 and the sliding block 4, and ensuring the accuracy and stability of power transmission during rotation.

[0041] Referring again to Figures 3 and 4, to ensure balanced force distribution, in this embodiment, mounting grooves 11 are provided on both sides of the base 1, and two sliding blocks 4 are also provided, corresponding one-to-one with the mounting grooves 11. The sliding blocks 4 on both sides of the base 1 are rotatably connected to the linkage component 2 through a rotating shaft 5 that runs through the width of the base 1. Specifically, as can be seen from Figures 2 and 7, the linkage component 2 also includes a horizontal part 2b located above the base 1. The horizontal part 2b is fixed to the upper end of the extension section 22 and extends to the right side of the base 1. The right end of the horizontal part 2b is provided with a downwardly extending bent part 2c, which is located on the right side of the front part of the base 1. The two ends of the rotating shaft 5 are rotatably connected to the front end of the extension section 22 and the front end of the bent part 2c, respectively. The design of the symmetrical mounting grooves 11 and sliding blocks 4 on both sides enables more uniform force transmission, further improving the stability of the connection between the base 1 and the linkage component 2, and ensuring the smoothness of the steering wheel angle adjustment.

[0042] Referring to Figures 3 and 7, the linkage component 2 is provided with a connecting hole b at the position corresponding to the rotating shaft 5. The rotating shaft 5 passes through the connecting hole b, and a nut 51 is provided at the end of the rotating shaft 5. By tightening the nut 51 into the connecting hole b, the linkage component 2 can be tightly connected to the base 1, avoiding loosening or relative displacement between the linkage component 2 and the base 1, thus ensuring the reliability and stability of the installation.

[0043] Furthermore, as shown in Figure 3, the nut 51 has a second inclined surface 5a in the circumferential direction, that is, the cross-sectional area of ​​the outer end of the nut 51 is larger than the cross-sectional area of ​​its inner end. With this structural design, after the nut 51 is tightened, it can press the sliding block 4 into the mounting groove 11 in the left and right directions, so that the sliding block 4 has zero gap in the vertical and left and right directions during installation, thereby further improving the tightness of the connection between the linkage component 2 and the base 1, and thus improving the flexibility and stability of the vertical adjustment of the base 1.

[0044] As shown in Figure 1, the power drive component 3 is a push rod motor located on the left side of the base 1. The base of the push rod motor is rotatably connected to the side of the base 1, and the front end of the push rod 31 of the push rod motor is rotatably connected to the lower end of the vertical section 21. After the push rod motor is started, the push rod 31 moves forward, driving the lower end of the vertical section 21 to move forward. This causes the linkage component 2 to rotate upward around the second hinge 2a, and the front end of the extension section 22 to rotate upward. Thus, under the connecting transmission action of the sliding block 4, the base 1 is driven to rotate upward around the first hinge 1a, realizing the upward angle adjustment of the steering wheel. Conversely, the push rod motor drives the push rod 31 to move backward to realize the downward angle adjustment of the steering wheel, which will not be elaborated here.

[0045] Furthermore, referring to Figure 1, a connecting support 32 is fixedly provided at the front end of the push rod 31, and this connecting support 32 is rotatably connected to the lower end of the vertical section 21. The back-and-forth movement of the push rod 31 drives the linkage component 2 to swing up and down around the second hinge 2a as a fulcrum. In this structure, the push rod motor has the technical advantages of simple and precise control and smooth operation. Specifically, the connecting support 32 is perpendicular to the push rod 31 and extends radially outward along the push rod 31, with the extended end of the connecting support 32 rotatably connected to the lower end of the vertical section 21. This design ensures the flexibility of the linkage component 2's movement.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
