[0038] like Figures 1 to 5As shown, this embodiment provides a steering adjustment mechanism, including a steering shaft 1, a fixing frame 2, and an adjustment assembly 3. The steering shaft 1 is provided with a connecting sleeve 11 and a guide member 12, the connecting sleeve 11 being perpendicular to the axis of the steering shaft 1. The guide member 12 is U-shaped, with its opening facing downwards. First guide grooves 121 are provided on opposite sides of the guide member 12, the extension directions of the two first guide grooves 121 being parallel to the axis of the steering shaft 1. The fixing frame 2 includes a first connecting plate 21, a second connecting plate 22, and a third connecting plate 23 connected sequentially. The first connecting plate 21 and the third connecting plate 23 are both perpendicular to the second connecting plate 22 and located on the same side of the second connecting plate 22, i.e., the opening of the fixing frame 2 faces downwards. Second guide grooves 24 and third guide grooves 25 are provided on both the first connecting plate 21 and the third connecting plate 23. The closed end of the fixing frame 2 can fit against the steering shaft 1. The outer walls of opposite sides of the guide member 12 are fitted against the inner sides of the first connecting plate 21 and the third connecting plate 23. The extension direction of the second guide groove 24 is parallel to the axis of the steering shaft 1, and the extension direction of the third guide groove 25 is set at an angle to the extension direction of the second guide groove 24. The first bolt 41 passes through the second guide groove 24 on the first connecting plate 21, the connecting sleeve 11, and the second guide groove 24 on the third connecting plate 23 in sequence and is connected to the first nut 42. The second bolt 51 passes through the third guide groove 25 on the first connecting plate 21, one first guide groove 121, the adjusting component 3, the other first guide groove 121, and the second guide groove 24 on the third connecting plate 23 in sequence and is connected to the second nut 52. The adjusting component 3 enables the two first guide grooves 121 to abut against the first connecting plate 21 and the third connecting plate 23 on the side opposite to each other.

[0039] It is understood that the steering adjustment mechanism proposed in this embodiment, by setting a connecting sleeve 11 and a first guide groove 121 on the steering shaft 1, and opening a second guide groove 24 and a third guide groove 25 on both the first connecting plate 21 and the third connecting plate 23, the first bolt 41 passes through the second guide groove 24 on the first connecting plate 21, the connecting sleeve 11 and the second guide groove 24 on the third connecting plate 23 in sequence and is connected to the first nut 42, and the second bolt 51 passes through the third guide groove 25 on the first connecting plate 21, one first guide groove 121, the adjustment component 3, the other first guide groove 121 and the third guide groove 25 on the third connecting plate 23 in sequence and is connected to the second nut 52, so that the steering shaft 1 can move relative to the fixed frame 2 along the axis of the steering shaft 1 to achieve height adjustment of the steering shaft 1, and can also rotate the steering shaft 1 around the axis of the connecting sleeve 11 to achieve forward and backward adjustment of the steering shaft 1. The adjustment component 3 fixes the steering shaft 1 after adjustment, so that the steering shaft 1 can be adjusted in both height and forward and backward, improving comfort.

[0040] In some embodiments, the adjusting assembly 3 includes a first cam 31, a second cam 32, and an adjusting handle 33. Both the first cam 31 and the second cam 32 have teeth on their opposite sides, with high and low positions. When the teeth of the first cam 31 and the second cam 32 are aligned at their high positions, the two first guide grooves 121 abut against the first connecting plate 21 and the third connecting plate 23, respectively. It is understood that by manipulating the adjusting handle 33, one of the first cam 31 and the second cam 32 can rotate relative to the other, thereby allowing the teeth on the first cam 31 and the second cam 32 to switch between being aligned at their high positions and being crossed at their high positions. When the teeth of the first cam 31 and the second cam 32 are aligned at their high positions, the adjusting assembly 3 presses and fixes the guide member 12 on the steering shaft 1 against the fixing frame 2, thereby fixing the steering shaft 1. When the teeth of the first cam 31 and the second cam 32 are crossed, the gap between the guide member 12 and the fixing frame 2 increases, allowing the steering shaft 1 to move axially or rotate around the axis of the connecting sleeve 11, thereby adjusting the position of the steering shaft 1. It should be noted that the structures of the first cam 31 and the second cam 32 are existing technologies and will not be described in detail here.

[0041] Furthermore, in some embodiments, both the first cam 31 and the second cam 32 are provided with bosses 34 on the sides that are axially away from each other. One of the two bosses 34 is engaged with the first guide groove 121, and the other is engaged with the adjustment handle 33.

[0042] Specifically, such as Figure 2 and Figure 4 As shown, in this embodiment, the boss 34 on the first cam 31 is disposed within the first guide groove 121 and can move within the first guide groove 121 along the setting direction of the first guide groove 121. The adjusting handle 33 is provided with an opening that mates with the boss 34. The thickness of the adjusting handle 33 is exactly the same as the thickness of the boss 34 on the second cam 32. It can be understood that the second bolt 51 only has a threaded head for connection with the second nut 52, and the middle is a smooth rod, which facilitates the movement of the steering shaft 1 within the first guide groove 121 and the third guide groove 25.

[0043] Furthermore, in order to improve the smoothness of rotation of the adjustment handle 33, in some embodiments, the adjustment assembly 3 further includes a bearing 35, one end of which is abutted against the side of the adjustment handle 33 away from the first cam 31 and the second cam 32, and the other end is connected to the first connecting plate 21 or the third connecting plate 23.

[0044] Specifically, such as Figure 2As shown, in this embodiment, the bearing 35 is a planar bearing 35, with one end connected to the adjusting handle 33 and the other end connected to the part away from the guide member 12. It is understood that by using the bearing 35, the friction between the adjusting handle 33 and the guide member 12 during rotation can be reduced, thus improving the lifespan of the adjusting handle 33 and reducing the force required for the operator to control the rotation of the second cam 32 via the adjusting handle 33. Furthermore, the planar bearing 35 contacts both the adjusting handle 33 and the guide member 12, resulting in a large contact area and therefore low pressure per unit area, allowing it to withstand very large radial and axial loads. Moreover, it operates very smoothly and does not produce the noise generated by the rolling elements colliding with the cage, as is common with rolling bearings 35.

[0045] Furthermore, in some embodiments, the adjustment handle 33 includes a connecting handle 331 and an auxiliary handle 332, one end of the connecting handle 331 is connected to the boss 34, and the other end is vertically connected to the side of the auxiliary handle 332.

[0046] Specifically, such as Figure 2 and Figure 5 As shown, in this embodiment, the end of the connecting handle 331 that connects to the second cam 32 gradually narrows towards the other end. This ensures that the second cam 32 can be easily rotated by the adjusting handle 33 while reducing the space occupied by the adjusting handle 33. The arc transition between the connecting handle 331 and the auxiliary handle 332 is more ergonomic and improves the comfort of using the adjusting handle 33.

[0047] More specifically, the auxiliary handle 332 and the connecting handle 331 are also equipped with a handle glove 333 corresponding to the auxiliary handle 332. The handle glove 333 is made of non-slip material such as rubber to further improve the comfort during use. The auxiliary handle 332 and the connecting handle 331 are provided with notches. The notches are designed to leave space between the handle glove 333 and the adjusting handle 33, so that the handle glove 333 will not be too close to the adjusting handle 33 and will not be difficult to remove under atmospheric pressure. This makes it easy to remove the handle glove 333 when it is old and damaged.

[0048] Furthermore, in some embodiments, the steering shaft 1 is provided with a first groove 13 and a second groove 14, the first groove 13 and the second groove 14 are respectively located on both sides of the radial direction of the steering shaft 1, the connecting sleeve 11 is provided in the first groove 13, and the guide member 12 is provided in the second groove 14.

[0049] Specifically, such as Figure 2As shown, a first groove 13 is provided on the upper side of the steering shaft 1, and a second groove 14 is provided on the lower side of the steering shaft 1. It can be understood that this arrangement allows the first bolt 41, which cooperates with the connecting sleeve 11, and the second bolt 51, which cooperates with the guide member 12, to be located on the radial sides of the steering shaft 1, respectively. After the steering shaft 1 is adjusted, the first bolt 41 and the second bolt 51 can further improve the fixing effect of the steering shaft 1.

[0050] Furthermore, such as Figure 6 As shown, in some embodiments, a pad 26 is provided on the side of the first connecting plate 21 and the third connecting plate 23 that are far apart from each other. A fourth guide groove 261 is provided on the pad 26, and the fourth guide groove 261 is correspondingly provided with the second guide groove 24. It can be understood that by providing the pad 26, the stress concentration at the second guide groove 24 can be reduced, and the loosening of the first bolt 41 during long-term rotation can be prevented, which would cause the connecting sleeve 11 to jam when moving with the steering shaft 1.

[0051] Furthermore, in some embodiments, the ends of the first connecting plate 21 and the third connecting plate 23 are bent outward to form connecting lugs 27, and fixing holes 271 are provided on the connecting lugs 27. Specifically, in this embodiment, screws pass through the fixing holes 271 and are connected to the vehicle frame. It can be understood that by bending the first connecting plate 21 and the third connecting plate 23 outward to form the connecting lugs 27, the contact area between the first connecting plate 21 and the third connecting plate 23 and the vehicle frame can be increased, thereby improving the installation stability and firmness of the fixing bracket 2 and providing strong support for subsequent adjustment of the steering shaft 1.

[0052] Furthermore, in some embodiments, the fixing frame 2 is also provided with a support plate 28. One side of the support plate 28 is perpendicularly connected to the connecting lug 27, and the other side is perpendicularly connected to the side of the first connecting plate 21 or the side of the third connecting plate 23. Specifically, as shown... Figure 2 As shown, in this embodiment, the support plate 28 is a right-angled triangle. One of the two right-angled sides of the support plate 28 is perpendicularly connected to the connecting lug 27, and the other right-angled side is perpendicularly connected to the outer side of the first connecting plate 21 or the outer side of the third connecting plate 23. It can be understood that by setting the support plate 28, the stability of the fixing frame 2 structure can be further enhanced.

[0053] On the other hand, this embodiment also provides a vehicle including the aforementioned steering adjustment mechanism. Since the vehicle provided by this invention has the aforementioned steering adjustment mechanism, it at least possesses the beneficial effects of the aforementioned steering adjustment mechanism, which will not be repeated here.

[0054] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
