[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0047] See Figures 1 to 7 This application discloses a steering column assembly. Specifically, the steering column assembly includes: a base 1, with first connecting plates 11 on both sides of the base 1, and first mounting grooves 110 provided on the first connecting plates 11; a steering shaft assembly 2, with second connecting plates 221 on both sides of the steering shaft assembly 2, the first connecting plates 11 abutting against the second connecting plates 221, and adjusting grooves 224 provided on the second connecting plates 221; and adjusting bolts 3, which pass through the first mounting grooves 110 and adjusting grooves 224. The first mounting grooves 110 are grooves extending along the height direction of the first connecting plates 11. Locking assembly 4 is connected to the side of the adjusting bolt 3 that extends out of the first mounting groove 110. Locking assembly 4 is used to lock or unlock the adjusting bolt 3 so that the adjusting bolt 3 can move along the adjusting groove 224 and / or the first mounting groove 110. Connecting post 7 has two ends connected to the upper side of the two first connecting plates 11 along the height direction of the first connecting plates 11, respectively. Elastic member 6 has one end connected to the connecting post 7 and the other end connected to the adjusting bolt 3. Elastic member 6 is used to drive the adjusting bolt 3 and the steering shaft assembly 2 back to the initial position after the locking assembly 4 is unlocked.
[0048] Specifically, such as Figure 1 As shown, for ease of explanation, the vertical direction of the vehicle can be defined as the first direction Z, that is, the vertical direction of the first connecting plate 11, as follows. Figure 1 As shown on the Z-axis, the left and right directions of the vehicle are defined as the second direction Y, as follows: Figure 1 The Y-axis direction shown is defined as the vehicle's forward / backward direction as the third direction X, as follows: Figure 1 The X-axis direction is shown.
[0049] like Figure 1 and Figure 2 As shown, the base 1 is used for fixed connection with the vehicle. A first connecting plate 11 is provided on each side of the base 1 along the second direction Y, and a second connecting plate 221 is provided on each side of the steering shaft assembly 2 along the second direction Y. The first connecting plate 11 and the second connecting plate 221 abut against each other along the second direction Y.
[0050] Two first connecting plates 11 are respectively provided with first mounting grooves 110. The two first mounting grooves 110 have the same shape and size. The first mounting grooves 110 extend along the first direction Z on the first connecting plate 11. The first mounting grooves 110 can be rectangular grooves, waist-shaped grooves, etc. The first mounting grooves 110 can be used to realize the height adjustment of the steering shaft assembly 2.
[0051] Two second connecting plates 221 are provided with adjustment grooves 224. The adjustment grooves 224 can be arc-shaped grooves, circular grooves, or rectangular grooves set at an angle to the first mounting groove 110, etc. The adjustment grooves 224 can be used to realize the angle adjustment of the steering shaft assembly 2.
[0052] like Figures 1-4 As shown, the adjusting bolt 3 passes through the first mounting groove 110 of the two first connecting plates 11 and the adjusting groove 224 of the two second connecting plates 221 along the second direction Y. The adjusting bolt 3 moves along the first mounting groove 110 and / or the adjusting groove 224 to adjust the angle and / or height of the steering shaft assembly 2. The adjusting bolt 3 has an initial position within the first mounting groove 110 and the adjusting groove 224. This initial position specifically refers to the preset position of the adjusting bolt 3 within the first mounting groove 110 and the adjusting groove 224 when the steering column assembly is in an unadjusted state. This preset position ensures that the position of the steering column assembly can meet the requirements of multiple drivers when it is in an unadjusted state. For example, the preset position of the adjusting bolt 3 in the first mounting groove 110 can be the middle position of the first mounting groove 110, and the preset position of the adjusting bolt 3 in the adjusting groove 224 can be the center point of the adjusting groove 224.
[0053] The two ends of the adjusting bolt 3 extend from the two first mounting slots 110 respectively. The locking assembly 4 is connected to the end of the adjusting bolt 3 that extends from the first mounting slot 110. The locking assembly 4 can lock or unlock the adjusting bolt 3 between the first connecting plate 11 and the second connecting plate 221. When it is necessary to adjust the height of the steering shaft assembly 2, the steering shaft assembly 2 can be moved up and down along the first direction Z by manual or automatic means. That is, the second connecting plate 221 moves up and down relative to the first connecting plate 11 along the first direction Z. The adjusting bolt 3 is unlocked by the locking assembly 4. The adjusting bolt 3 can move up and down from the initial position in the first mounting slot 110, thereby changing the height of the steering shaft assembly 2. When the angle of the steering shaft assembly 2 needs to be adjusted, it can be rotated manually or automatically, that is, the second connecting plate 221 rotates relative to the first connecting plate 11. Similarly, the adjusting bolt 3 is unlocked by the locking assembly 4, allowing it to move from its initial position in the adjusting groove 224, thereby changing the angle of the steering shaft assembly 2. After adjusting to the target height and angle, the adjusting bolt 3 is re-locked using the locking assembly 4 to fix the position of the steering shaft assembly 2. The steering shaft assembly 2 is used to connect to the steering wheel in the vehicle, thus enabling the adjustment of the steering wheel height and angle.
[0054] Both ends of the connecting post 7 are fixedly connected to the upper side of the two first connecting plates 11 along the first direction Z. The fixed connection method may include, but is not limited to, welding or fastener connection. In some embodiments, the connecting post 7 can be a bolt. The two first connecting plates 11 are provided with threaded holes along the upper side of the first direction Z. The bolt is threadedly connected to the two threaded holes to achieve the fixed connection between the connecting post 7 and the two first connecting plates 11.
[0055] One end of the elastic element 6 is connected to the connecting post 7. The elastic element 6 can be a spring, elastic band, or other elastic component. The other end of the elastic element 6 is fixedly connected to the adjusting bolt 3. When the adjusting bolt 3 is in the initial position in the first mounting groove 110 and / or adjusting groove 224, the elastic element 6 is in a relaxed state. After the locking assembly 4 is unlocked, the adjusting bolt 3 moves in the first mounting groove 110 and / or adjusting groove 224. Since the end of the elastic element 6 connected to the connecting post 7 is fixed, the other end of the elastic element 6 will follow the movement of the adjusting bolt 3, causing the elastic element 6 to be compressed or stretched, thereby generating an elastic force in the elastic element 6. Thus, after the locking assembly 4 is unlocked again, the elastic force of the elastic element 6 can drive the adjusting bolt 3 and the steering shaft assembly 2 to return to the initial position.
[0056] In this embodiment, a connecting column 7 is connected to the upper side of the first connecting plates 11 on both sides of the base 1 in the vertical direction; an elastic element 6 is connected between the connecting column 7 and the adjusting bolt 3. The elastic element 6 can provide elastic force to the adjusting bolt 3 after the locking assembly 4 unlocks the adjusting bolt 3, so that the adjusting bolt 3 and the steering shaft assembly 2 return to the initial position. In this way, different drivers can adjust the height and angle of the steering shaft assembly 2 from the same initial position, thereby reducing the operation time and operation complexity of the steering column assembly adjustment and improving the driver's operating experience.
[0057] In some alternative embodiments, the height of the first mounting groove 110 along the first direction Z is the height adjustment stroke of the adjusting bolt 3, which can be 40mm-60mm. In practical applications, by setting the length of the first limiting groove to 40-60mm, the adjustment range of the steering shaft assembly 2 height can be increased, meeting the diverse needs of the driver for steering wheel height adjustment and improving the driver's driving comfort.
[0058] Preferably, the height of the first mounting groove 110 along the first direction Z is 60mm. At this point, the height adjustment range of the steering shaft assembly 2 is at its maximum, which can further meet the diverse needs of the driver for steering wheel height adjustment and improve the driver's driving comfort.
[0059] In some alternative embodiments, such as Figures 3-4 As shown, the elastic element 6 is a spring. Specifically, the two ends of the spring are respectively sleeved on the connecting column 7 and the adjusting bolt 3. The adjusting bolt 3 moves in the first mounting groove 110 and / or the adjusting groove 224, causing the spring to be stretched or compressed, thereby generating an elastic force in the spring. The elastic force of the spring drives the adjusting bolt 3 and the steering shaft assembly 2 to return to the initial position. In practical applications, compared with other complex elastic elements 6, the cost of the spring is lower, which can reduce the cost of the steering column assembly.
[0060] In some embodiments, there is at least one elastic element 6, and at least one elastic element 6 is disposed along the extension direction of the connecting post 7.
[0061] In some alternative embodiments, such as Figures 3-4 As shown, there can be only one elastic element 6, which is arranged along the extension direction of the connecting column 7. This single elastic element 6 can drive the adjusting bolt 3 and the steering shaft assembly 2 to return to their initial positions. In practical applications, the use of a single elastic element 6 can simplify the structure of the steering column assembly and reduce costs.
[0062] In other alternative embodiments, there can be multiple elastic elements 6. For example, there can be 2, 3, 4, etc., and this application does not specifically limit this. Multiple elastic elements 6 can be arranged side by side along the extension direction of the connecting column 7. In practical applications, multiple elastic elements 6 can more quickly drive the adjusting bolt 3 and the steering shaft assembly 2 back to their initial positions, which can reduce the operation time of adjusting the steering column assembly and improve the driver's operating experience.
[0063] Optionally, the adjustment groove 224 is an arc-shaped groove, and the steering column assembly further includes: an adjustment component 9, and the first connecting plate 11 is also provided with a second mounting groove 112, which is a groove extending in the vertical direction; the adjustment component 9 passes through the second mounting groove 112 and is connected to the second connecting plate 221, and the adjustment component 9 is movable in the second mounting groove 112.
[0064] Specifically, such as Figure 5 As shown, the adjustment groove 224 is an arc-shaped groove, which gives the adjustment groove 224 a certain curvature. The adjustment bolt 3 can move in the adjustment groove 224 to realize the angle adjustment of the steering shaft assembly 2.
[0065] like Figures 1-6 As shown, the second mounting groove 112 on the first connecting plate 11 has the same height as the first mounting groove 110 along the first direction Z. The second mounting groove 112 can be a rectangular groove or an oblong groove, etc. The adjusting component 9 moves up and down along the first direction Z in the second mounting groove 112. Thus, when it is necessary to adjust the height of the steering shaft assembly 2, the adjusting bolt 3 is unlocked by the locking component 4, and the adjusting bolt 3 can move up and down from its initial position in the first mounting groove 110. At the same time, by the adjusting component 9 moving up and down synchronously in the second mounting groove 112, the height position of the second connecting plate 221 relative to the first connecting plate 11 can be changed, thereby realizing the overall height adjustment of the steering column assembly and improving the driver's driving comfort. The steering shaft assembly 2 is installed in the second mounting groove 112 via the adjusting component 9, which can support the steering shaft assembly 2 and ensure the relative stability of the steering column assembly relative to the base 1.
[0066] Optionally, a second through hole 223 is provided on the second connecting plate 221 at a position corresponding to the second mounting groove 112; the adjusting assembly 9 includes: a connecting bolt 91, a slot washer 93 and a connecting nut 94, the slot washer 93 is at least partially accommodated in the second mounting groove 112 and the slot washer 93 is movable in the second mounting groove 112; the connecting bolt 91 passes through the slot washer 93 and the second through hole 223 and is connected to the connecting nut 94.
[0067] like Figures 5-7As shown, the second connecting plate 221 is provided with a second through hole 223 penetrating the second connecting plate 221. The second through hole 223 is disposed opposite to the second mounting groove 112. The slotted gasket 93 is at least partially accommodated in the second mounting groove 112 and contacts the groove wall of the second mounting groove 112. The slotted gasket 93 is provided with a through hole penetrating the slotted gasket 93. The connecting bolt 91 passes through the through hole on the slotted gasket 93 and the second through hole 223 and is threadedly connected to the connecting nut 94. In this way, the connecting bolt 91 can be fixed on the second connecting plate 221 by the connecting nut 94. When the second connecting plate 221 moves up and down relative to the first connecting plate 11 in the first direction Z, the slotted gasket 93 moves up and down in the second mounting groove 112 in the first direction Z, thereby realizing the adjustment of the height of the steering shaft assembly 2. In this embodiment, since the adjusting bolt 3, the slotted gasket 93 and the connecting nut 94 in the adjusting component are all common standard parts, they are easy to purchase and produce, thereby reducing the manufacturing cost of the steering column assembly.
[0068] In some embodiments, such as Figure 7 As shown, the adjusting assembly 9 also includes a bushing 92, which is fitted onto the portion of the connecting bolt 91 located in the first mounting groove 110. A slotted shim 93 is fitted onto the outer side of the bushing 92. The inner diameter of the slotted shim 93 can be slightly larger than the outer diameter of the bushing 92. When the second connecting plate 221 rotates relative to the first connecting plate 11, the slotted shim 93 can rotate around the bushing 92, and the bushing 92 can rotate around the connecting bolt 91 to assist in adjusting the angle of the steering shaft assembly 2.
[0069] Optionally, the slot gasket 93 includes a gasket body 931 and a protrusion 932 connected to the gasket body 931. The protrusion 932 is accommodated in the second mounting groove 112, and the shape of the protrusion 932 is adapted to the shape of the second mounting groove 112. The gasket body 931 abuts against the first connecting plate 11.
[0070] like Figure 6 and Figure 7As shown, the slot shim 93 may include a shim body 931 and a protrusion 932 protruding from the shim body 931. The protrusion 932 is accommodated in a second mounting groove 112. The shape of the second mounting groove 112 is adapted to the shape of the protrusion 932. The second mounting groove 112 may be a rectangular groove, and the protrusion 932 may be a rectangular block. The protrusion 932 is accommodated in the second mounting groove 112 and can move within the second mounting groove 112 to adjust the height of the steering shaft assembly 2. The shim body 931 may be a cylindrical block, and the rectangular block has a smaller size. The diameter of the gasket body 931 is such that when the protrusion 932 is located in the first mounting groove 110, the gasket body 931 is located outside the first mounting groove 110 and abuts against the surface of the first connecting plate 11. In practical applications, by setting the protrusion 932 to be accommodated in the first mounting groove 110, and by abutting the surface of the first connecting plate 11 through the gasket body 931, a supporting function can be provided. This can reduce the sliding or offset of the slot gasket 93 during height adjustment, improve the stability of the slot gasket 93 during height adjustment, and improve the stability of the steering column assembly height adjustment.
[0071] Optionally, the steering column assembly also includes a limiting member 8, and the first connecting plate 11 is also provided with a third mounting groove 111, which is a polygonal groove; one end of the limiting member 8 is fixed to the second connecting plate 221, and the other end is accommodated in the third mounting groove 111.
[0072] Specifically, such as Figure 1 , Figure 5 and Figure 6 As shown, the two first connecting plates 11 are provided with a third mounting groove 111. One end of the limiting member 8 is accommodated in the third mounting groove 111, and the other end is fixedly connected to the second connecting plate 221 by welding, threaded connection or other means. The third mounting groove 111 is a polygonal groove. The shape of the third mounting groove 111 can determine the movement range and angle adjustment limit of the limiting member 8. The polygonal groove can be specifically set according to the angle adjustment range of the steering column assembly in actual application.
[0073] In practical applications, when the height of the steering shaft assembly 2 needs to be adjusted, it can be rotated manually or automatically. Specifically, the second connecting plate 221 rotates relative to the first connecting plate 11. The adjusting bolt 3 is unlocked by the locking assembly 4, allowing it to move from its initial position within the adjusting groove 224. Simultaneously, the limiting member 8 moves within the third mounting groove 111, enabling angle adjustment of the steering shaft assembly 2. Furthermore, the limiting member 8 contacts the wall of the third mounting groove 111, limiting the angle adjustment of the steering shaft assembly 2. In this embodiment, by setting the limiting member 8 in cooperation with the third mounting groove 111, a more precise angle adjustment range and limiting effect can be provided for the angle adjustment of the steering shaft assembly 2, meeting the driver's different angle adjustment needs and improving driving comfort.
[0074] In some alternative embodiments, the third mounting slot 111 has a highest position, a middle position, and a lowest position in the first direction Z, such as... Figure 5 and Figure 6 As shown, the third mounting groove 111 can be divided into three different segments in the first direction Z. At the highest position, the width of the third mounting groove 111 along the third direction X is the largest. When the limiting member 8 is in the highest position, it can rotate forward 18° and backward -12° along the third direction X. That is, at the highest position, the adjustment range of the steering shaft assembly 2 angle is +18° to -12°. At the middle position, the width of the third mounting groove 111 along the third direction X is moderate. When the limiting member 8 is in the middle position, it can rotate forward 11° and backward -10° along the third direction X. That is, at the middle position, the adjustment range of the steering shaft assembly 2 angle is +11° to -10°. At the lowest position, the width of the third mounting groove 111 along the third direction X is the smallest. When the limiting member 8 is in the lowest position, it can rotate forward 0° and backward -10° along the third direction X. That is, at the lowest position, the adjustment range of the steering shaft assembly 2 angle is 0° to -10°. In the embodiments of this application, the corresponding angle adjustment range is increased at different positions, and each position has a large angle adjustment range, which allows the driver to adjust the angle within a larger range and improves the driver's driving comfort.
[0075] Optionally, a first through hole 222 is provided on the second connecting plate 221 at a position corresponding to the third mounting groove 111; the limiting member 8 includes a limiting screw 81 and a limiting nut 82. The limiting screw 81 includes a screw head and a screw shank. The screw head is housed in the third mounting groove 111; the screw shank passes through the first through hole 222 and is connected to the limiting nut 82.
[0076] Specifically, such as Figure 5As shown, a first through hole 222 is provided on the second connecting plate 221 at the position corresponding to the third mounting groove 111. The first through hole 222 penetrates the second connecting plate 221. The screw head of the limiting screw 81 is located in the third mounting groove 111, and the screw shank of the limiting screw 81 passes through the first through hole 222 and is threadedly connected to the limiting nut 82. The angle adjustment of the steering shaft assembly 2 can be limited by the contact between the screw head and the groove wall of the third mounting groove 111. The limiting screw 81 can be fixed on the second connecting plate 221 by the screw shank and the limiting nut 82. The movement of the second connecting plate 221 causes the limiting screw 81 to move within the third mounting groove 111, thereby realizing the adjustment of the steering wheel angle. In this embodiment, the adjustment and limitation of the steering column assembly angle are realized only by the cooperation of the limiting screw 81 and the limiting nut 82. The structure of the limiting component 8 is simpler, reducing the number of components and lowering the cost of the steering column assembly.
[0077] Optionally, the first mounting groove 110, the third mounting groove 111, and the second mounting groove 112 are sequentially spaced apart in the front-to-back direction on the first connecting plate 11.
[0078] After the locking assembly 4 unlocks the steering shaft assembly 2, the adjusting bolt 3 moves in the first mounting groove 110, and the adjusting assembly 9 moves synchronously in the second mounting groove 112 to adjust the height of the steering shaft assembly 2. The adjusting bolt 3 then moves in the adjusting groove 224, and the limiting member 8 moves synchronously in the third mounting groove 111 to adjust the angle of the steering shaft assembly 2. In practical applications, such as... Figure 6 As shown, by arranging the first mounting groove 110, the third mounting groove 111, and the second mounting groove 112 sequentially along the third direction X, the height adjustment and angle adjustment can be adjusted step by step. That is, the height can be adjusted first, and then the angle can be adjusted on this basis. This allows the height adjustment and angle adjustment to be adjusted independently within a large range, thereby increasing the adjustment range of the steering wheel height and angle, meeting the diverse needs of the driver for steering wheel height and angle adjustment, and improving the driver's driving comfort.
[0079] The following explains in detail the specific adjustment process of the steering column assembly proposed in the embodiments of this application.
[0080] When adjusting the height of the steering shaft assembly 2, the adjusting bolt 3 is unlocked by the locking assembly 4. The steering shaft assembly 2 can then be moved up and down along the first direction Z, either manually or automatically. Specifically, the second connecting plate 221 moves up and down relative to the first connecting plate 11 along the first direction Z. The adjusting bolt 3 can move up and down from its initial position within the first mounting groove 110. Simultaneously, the adjusting assembly 9 moves up and down synchronously within the second mounting groove 112, thus adjusting the height of the steering column assembly. When adjusting the angle of the steering shaft assembly 2, it can be rotated manually or automatically. Specifically, the second connecting plate 221 rotates relative to the first connecting plate 11. The adjusting bolt 3 can move from its initial position along the arc path of the adjusting groove 224. Simultaneously, the limiting member 8 moves within the third mounting groove 111, thus adjusting the angle of the steering column assembly. The contact between the limiting member 8 and the wall of the third mounting groove 111 limits the angle adjustment of the steering shaft assembly 2. After adjusting to the target height and angle, the adjusting bolt 3 is re-locked by the locking assembly 4 to fix the position of the steering shaft assembly 2.
[0081] In some alternative embodiments, the steering shaft assembly 2 includes a steering shaft 21 and a bracket 22, one end of the steering shaft 21 is connected to the bracket 22, and the other end is used to connect to the steering wheel; first connecting plates 11 are provided on both sides of the bracket 22.
[0082] In some optional embodiments, the locking assembly 4 may include a handle 40, a lock body 41, and a locking nut 42. The lock body 41 is connected to the handle 40. One end of the adjusting bolt 3 extending out of the two first mounting slots 110 is connected to the lock body 41 and the handle 40, and the other end is threadedly connected to the locking nut 42. Rotating the handle 40 causes the lock body 41 to rotate. The lock body 41 is used to lock or unlock the adjusting bolt 3. It should be noted that the specific structure of the lock body 41 can be specifically set according to the actual situation, and this application embodiment does not specifically limit it.
