Description

Technical Field

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

[0002] In most vehicles today, the steering wheel has both height and fore-and-aft adjustment functions to ensure that the driver can operate the steering wheel in the optimal posture. The height adjustment function is typically achieved by controlling the steering tube to rotate vertically relative to the vehicle body (angle adjustment).

[0003] However, existing vehicle steering column angle adjustment mechanisms on the market have certain limitations in design and application. Some traditional structures have large installation gaps when adjusting the steering wheel height. Over time, this can cause the steering wheel to wobble during driving and may also affect the overall lifespan of the structure due to long-term wear, posing safety hazards.

[0004] Therefore, achieving zero-clearance installation of the steering column and ensuring the overall structural stability has become a pressing technical requirement for the automotive industry. Utility Model Content

[0005] In view of this, the present invention provides a vehicle steering column angle adjustment mechanism, which can achieve zero-gap assembly of the mechanism and improve the stability of the overall structure.

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

[0007] A vehicle steering column angle adjustment mechanism, the key feature of which is that it includes a mounting base and a linkage component, both of which are rotatably mounted on the vehicle, and a drive assembly is provided between the mounting base and the linkage component, the drive assembly being used to drive the linkage component to rotate relative to the vehicle.

[0008] The mounting base and the linkage component are connected by a deformable component, which can adapt to pressure and deform to maintain a continuous, gapless connection between the mounting base and the linkage component; when the linkage component rotates relative to the vehicle, the deformable component can drive the mounting base to rotate relative to the vehicle.

[0009] The mounting base is used to connect the vehicle steering column.

[0010] With the above structure, in application, the steering column of the vehicle steering system is fixedly mounted in the mounting base, and the steering wheel is installed at the front end of the steering column. The drive component drives the linkage component to rotate relative to the vehicle. Under the connecting transmission action of the deformable component, the mounting base can be forced to rotate up and down relative to the vehicle, which in turn drives the steering column to rotate up and down relative to the vehicle, thereby realizing the height adjustment of the steering wheel. By setting the deformable component between the mounting base and the linkage component, zero-clearance installation of the mechanism can be achieved. During the up and down adjustment of the steering wheel, the linkage component and the mounting base can always maintain a gapless connection, improving the stability of the overall structure.

[0011] Preferably, the mounting 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 used for rotatable connection to the vehicle, and the deformable assembly connects between the mounting base and the front of the linkage component. This structure makes the rotatable connection between the mounting base and the linkage component on the vehicle more stable.

[0012] Preferably, the system also includes a linkage support for fixed mounting inside the vehicle, with the linkage component rotatably connected to the linkage support. Using this structure, the linkage support provides a stable mounting reference for the vehicle steering column angle adjustment mechanism, ensuring a stable connection between the linkage component, mounting base, and other components and the vehicle.

[0013] Preferably, the mounting base has a V-shaped groove extending along its length on its side. The deformable component includes a deformable block that can be slidably installed in the V-shaped groove. The deformable block is a plastic part constructed with a V-shaped structure matching the cross-section of the V-shaped groove. A weakened opening is provided in the middle of the deformable block. The deformable block is rotatably connected to the linkage component via a rotating shaft. With this structure, by providing the weakened opening, the deformable block can remain in a contracted and compressed state after being installed in the V-shaped groove. Even during relative movement of the deformable block, a tight connection can be maintained between the mounting base and the linkage component, thus better achieving zero-gap installation between the mounting base and the linkage component.

[0014] Preferably, the mounting base has V-grooves on both sides, and the deformable blocks on both sides are rotatably connected to the linkage component via a pivot shaft that runs through the width of the mounting base. This structure, with its symmetrical V-grooves and deformable blocks, increases the contact area between the deformable components and the mounting base, resulting in more uniform force transmission.

[0015] Preferably, the end of the rotating shaft is provided with a tightening nut to ensure a tight connection between the linkage component and the mounting base; the tightening nut has a circumferentially inclined surface. With this structure, after the tightening nut is tightened, the deformable block can be pressed into the V-groove in a slightly deformed state, resulting in zero clearance in both the vertical and horizontal directions of the deformable block during installation, thereby further improving the tightness of the connection between the linkage component and the mounting base.

[0016] Preferably, the bottom of the V-groove has a strip-shaped hole that extends along the length of the mounting base. The rotating shaft passes through the strip-shaped hole and is slidably supported on it. This structure provides space for the rotating shaft to move back and forth, allowing it to move in conjunction with the deformable block.

[0017] Preferably, the linkage component has a vertical section located on one side of the mounting 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 driving component is used to drive the vertical section to rotate around the second hinge portion. The deformation component is located at the front end of the extension section. With this structure, the linkage component can more effectively drive the mounting base to rotate, offering advantages such as simple structure, good stability, and flexible rotation.

[0018] Preferably, the drive assembly is a push rod motor, which includes a lead screw, the end of which is rotatably connected to the lower end of the vertical section. With this structure, the lead screw moves forward, driving the lower end of the vertical section forward, thereby causing the entire linkage component to rotate upward around the second hinge, and the front end of the extension section to rotate upward. Thus, under the connecting transmission action of the deformable assembly, the mounting base is forced to rotate upward around the first hinge, achieving upward angle adjustment of the steering wheel.

[0019] Preferably, a connecting support is fixedly provided at the end of the lead screw, and the connecting support is rotatably connected to the lower end of the vertical section. With the above structure, the forward and backward movement of the lead screw can drive the linkage component to swing up and down around the pin.

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

[0021] 1. When using the vehicle steering column angle adjustment mechanism provided by this utility model, the steering column of the vehicle steering system is fixedly assembled in the mounting base. The steering wheel is installed at the front end of the steering column. The drive component drives the linkage component to rotate relative to the vehicle. Under the connecting transmission action of the deformation component, the mounting base can be forced to rotate up and down relative to the vehicle, which in turn drives the steering column to rotate up and down relative to the vehicle, thereby realizing the height adjustment of the steering wheel.

[0022] 2. The vehicle steering column angle adjustment mechanism provided by this utility model can achieve zero-gap installation of the mechanism by setting a deformable component between the mounting base and the linkage component. During the up and down adjustment of the steering wheel, the linkage component and the mounting base can always maintain a gapless connection, which improves the stability of the overall structure and allows the driver to feel a smooth and seamless operating experience when adjusting the steering wheel angle.

[0023] 3. The vehicle steering column angle adjustment mechanism provided by this utility model allows the deformation component to absorb the torsional interference caused by the rotation direction of the linkage component during the up-and-down rotation of the mounting base, thus avoiding wear between parts and extending the service life.

[0024] 4. The V-block is flexibly installed in the V-groove, which not only ensures zero-clearance assembly but also avoids excessive adjustment resistance, making it a solution with excellent overall performance. Attached Figure Description

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

[0033] like Figure 1 and Figure 2 As shown, a vehicle steering column angle adjustment mechanism includes a mounting base 1 and a linkage component 3. The mounting base 1 is used to connect the vehicle steering column A1. In this embodiment, the mounting base 1 has a front end and a rear end; in application, the rear end of the mounting base 1 is hinged to the vehicle body A. Figure 2As can be seen, the linkage component 3 is located at the front of the mounting base 1, and the linkage component 3 is used to rotate and be mounted on the vehicle body A. A drive assembly 4 is provided between the mounting base 1 and the linkage component 3, and the drive assembly 4 can drive the linkage component 3 to rotate relative to the vehicle.

[0034] In this embodiment, the mounting base 1 and the linkage component 3 are connected by a deformable component. When the linkage component 3 rotates relative to the vehicle, the deformable component can drive the mounting base 1 to rotate relative to the vehicle. The deformable component can adapt to deformation under pressure so that the mounting base 1 and the linkage component 3 maintain a continuous and gapless connection.

[0035] Based on the above structural design, in application, the steering column A1 of the vehicle steering system is fixedly assembled in the mounting base 1, and the steering wheel A2 is installed at the front end of the steering column A1. The drive component 4 drives the linkage component 3 to rotate relative to the vehicle. Under the connecting transmission action of the deformation component, the mounting base 1 can be forced to rotate up and down relative to the vehicle, which means that the steering column A1 is driven to rotate up and down relative to the vehicle, thereby realizing the height adjustment of the steering wheel A2.

[0036] The advantages of the above structural design are as follows: By setting a deformable component between the mounting base 1 and the linkage component 3, zero-gap installation of the mechanism can be achieved. During the up-and-down adjustment of the steering wheel, the linkage component 3 and the mounting base 1 can always maintain a gapless connection, improving the overall structural stability and allowing the driver to experience a smooth and seamless operation when adjusting the steering wheel angle. In addition, during the up-and-down rotation of the mounting base 1 driven by the linkage component 3, the deformable component can absorb the torsional interference caused by the rotation direction of the linkage component 3, avoiding wear between parts and thus extending service life.

[0037] Furthermore, combined Figure 1 and 2 As shown, the rear end of the mounting base 1 has a first hinge portion 1a, and the rear end of the linkage component 3 has a second hinge portion 3g. Both the first hinge portion 1a and the second hinge portion 3g are used for rotatable connection to the vehicle. The linkage component 3 is located at the front of the mounting base 1, and the deformable assembly 5 connects the mounting base 1 and the front of the linkage component 3. The drive assembly 4 drives the linkage component 3 to rotate up and down around the second hinge portion 3g. Under the connecting transmission action of the deformable assembly, the mounting base 1 can be forced to rotate up and down around the first hinge portion 1a, realizing the height adjustment of the steering wheel. This structural design makes the rotatable connection between the mounting base 1 and the linkage component 3 on the vehicle more stable.

[0038] refer to Figure 1 and Figure 2 The vehicle steering column angle adjustment mechanism also includes a linkage support 2. In practical applications, the linkage support 2 is bolted to the vehicle body A, and then combined with... Figure 4 The second hinge 3g of the linkage component 3 is rotatably connected to the linkage support 2 via pin a. The linkage support 2 provides a stable mounting reference for the vehicle steering column angle adjustment mechanism, ensuring a stable connection between the linkage component 3, the mounting base 1, and other components and the vehicle.

[0039] refer to Figure 2 and Figure 7 The specific structure of the linkage component 3 is as follows: In this embodiment, the linkage component 3 has a vertical section 31 located on the left side of the mounting base 1. The upper end of the vertical section 31 has a vertically extending forward extension section 32. The second hinge portion 3g is located at the upper end of the vertical section 31, and the deformation component is located at the front end of the extension section 32. The drive component 4 drives the lower end of the vertical section 31 to swing back and forth relative to the vehicle, thus enabling the linkage component 3 to rotate as a whole around the second hinge portion 3g. The rotation of the front end of the extension section 32 forces the mounting base 1 to rotate up and down around the first hinge portion 1a under the connecting transmission action of the deformation component. Through the above structural design, the linkage component 3 can more effectively drive the mounting base 1 to rotate, possessing the technical advantages of simple structure, good stability, and flexible rotation.

[0040] like Figures 3 to 5 As shown, a V-shaped groove 11 extending along its length is provided on the left side of the mounting base 1. The opening of the V-shaped groove 11 faces the outer left side of the mounting base 1. The deformable component includes a deformable block 5 that can be slidably installed in the V-shaped groove 11. In this embodiment, the deformable block 5 is a plastic part with a certain degree of flexibility. The deformable block 5 is constructed into a V-shaped structure that matches the cross-section of the V-shaped groove 11. A weakened opening 51 is provided in the middle of the deformable block 5. The deformable block 5 is rotatably connected to the linkage component 3 through a rotating shaft 6. Since the center lines of the first hinge part 1a, the second hinge part 3g, and the rotating shaft 6 are not coincident, when the linkage component 3 rotates about the second hinge part 3g, the deformable block 5 moves back and forth relative to the mounting base 1, and at the same time, the deformable block 5 also rotates relative to the linkage component 3. By setting the weakened opening 51, the deformable block 5 can remain in a contracted and compressed state after being installed in the V-groove 11. Even during the relative movement of the deformable block 5, it can ensure that the mounting base 1 and the linkage component 3 always maintain a tight connection, thus better achieving zero-gap installation between the mounting base 1 and the linkage component 3. In addition, compared with other structures such as rectangles, the V-shaped deformable block 5 can better absorb and buffer the stress and impact generated by swinging, protecting the mounting base 1 and the linkage component 3 from damage, and further improving the smoothness and flexibility during the up and down adjustment of the steering wheel.

[0041] Reference Figure 3 and Figure 5The bottom of the V-groove 11 is provided with a strip hole 12, which extends along the length of the mounting base 1. The rotating shaft 6 passes through the strip hole 12 and is slidably supported on the strip hole 12. The setting of the strip hole 12 provides space for the back-and-forth movement of the rotating shaft 6, so that the rotating shaft 6 can move in conjunction with the deformation block 5.

[0042] To ensure force balance, such as Figure 3 and 4 As shown, in this embodiment, V-grooves 11 are provided on both sides of the mounting base 1, and there are two deformable blocks 5, each corresponding to one of the V-grooves 11. The deformable blocks 5 on both sides of the mounting base 1 are rotatably connected to the linkage component 3 via a rotating shaft 6 that runs through the width of the mounting base 1. Specifically, the linkage component 3 also includes a horizontal part 3a located above the mounting base 1. The horizontal part 3a is fixed to the upper end of the extension section 32 and extends to the right side of the mounting base 1. The right end of the horizontal part 3a has a downwardly extending bent part 3b, which is located on the right side of the front of the mounting base 1. The two ends of the rotating shaft 6 are rotatably connected to the front end of the extension section 32 and the front end of the bent part 3b, respectively. The design of the symmetrical V-grooves 11 and deformable blocks 5 on both sides increases the contact area between the deformable component and the mounting base 1, making the force transmission more uniform and further improving the stability of the connection between the mounting base 1 and the linkage component 3, thus ensuring the smoothness of the steering wheel angle adjustment.

[0043] Revisit Figure 3 and Figure 7 The linkage component 3 is provided with a first connecting hole b at the position corresponding to the rotating shaft 6. The rotating shaft 6 passes through the first connecting hole b and has a tightening nut 61 at the end. By tightening the tightening nut 61 into the first connecting hole b, the linkage component 3 can be tightly connected to the mounting base 1, avoiding loosening or relative displacement between the linkage component 3 and the mounting base 1, thus ensuring the reliability and stability of the installation.

[0044] Furthermore, by Figure 3 It can be seen that the tightening nut 61 has a circumferential inclined surface 611, that is, the cross-section of the outer end of the tightening nut 61 is larger than the cross-section of its inner end. With this structural design, after the tightening nut 61 is tightened, the deformable block 5 can be pressed into the V-groove 11 in a slightly deformed state, so that the deformable block 5 has zero gap in the vertical and horizontal directions of installation, thereby further improving the tightness of the connection between the linkage component 3 and the mounting base 1, and thus improving the flexibility and stability of the vertical adjustment of the mounting base 1.

[0045] Depend on Figure 2As shown, the drive component 4 is a push rod motor located on the left side of the mounting base 1. The base of the push rod motor is rotatably connected to the side of the mounting base 1, and the front end of the lead screw 41 of the push rod motor is rotatably connected to the lower end of the vertical section 31. After the push rod motor is started, the lead screw 41 moves forward, driving the lower end of the vertical section 31 to move forward. This causes the linkage component 3 to rotate upward around the second hinge 3g, and the front end of the extension section 32 to rotate upward. Thus, under the connecting transmission action of the deformation component, the mounting base 1 is forced to rotate upward around the first hinge 1a, thereby achieving the upward angle adjustment of the steering wheel. Conversely, the push rod motor drives the lead screw 41 to move backward to achieve the downward angle adjustment of the steering wheel, which will not be elaborated here.

[0046] Please refer to Figure 4 A connecting support 42 is fixedly provided at the front end of the lead screw 41, and this connecting support 42 is rotatably connected to the lower end of the vertical section 31. The forward and backward movement of the lead screw 41 can drive the linkage component 3 to swing up and down around the pin a as the fulcrum. In this structure, the push rod motor has the technical advantages of simple and precise control and smooth operation.

[0047] For details, please refer to the following: Figure 4 The connecting branch 42 is perpendicular to the lead screw 41 and extends radially outward along the lead screw 41. The extended end of the connecting branch 42 is rotatably connected to the lower end of the vertical section 31. This design ensures the flexibility of the linkage component 3.

[0048] 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.
