[0042] In order to thoroughly understand the present invention, a detailed structure will be presented in the following description to illustrate the technical solution proposed by the present invention. The optional embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0043] like Figure 1 As shown, the steering column mechanism of the utility model embodiment includes:

[0044] The first pipe string 1 and the second pipe string 2 are slidably connected to each other.

[0045] More specifically, the first column 1 is one of the main parts of the steering column mechanism. The first column 1 carries the steering wheel and steering system components related thereto. The first column 1 can slide relative to the second column 2 to adjust the height of the steering column to meet different driving needs of the driver.

[0046] The second pipe column 2 serves as a sliding track for the first pipe column 1 . The second pipe column 2 provides support and guidance for the sliding of the first pipe column 1 , thereby ensuring that the first pipe column 1 can slide steadily and smoothly inside the second pipe column 2 .

[0047] The driving assembly is suitable for driving the first column 1 to slide relative to the second column 2. More specifically, the driving assembly is a core component for realizing the height adjustment of the steering column. Through a specific driving mechanism (such as a motor, a manual adjustment lever, etc.), the driving assembly can generate sufficient force to push the first column 1 to slide relative to the second column 2.

[0048] The motion component 5 is suitable for transmission connection with the driving component, and the motion component 5 is suitable for decomposing part of the force generated when the driving component drives the first pipe column 1 to move relative to the second pipe column 2. More specifically, the motion component 5 is transmission connected with the driving component, and can receive and transmit the force generated by the driving component while being able to decompose part of the force generated by the driving component, thereby reducing the friction between the first pipe column 1 and the second pipe column 2 during the sliding process, thereby reducing the generation of wear and abnormal noise. The specific implementation of the motion component 5 may include mechanical structures such as gears, levers, and sliding blocks, and the decomposition and transmission of force are achieved through the ingenious combination and coordination of these structures.

[0049] Preferably, the driving assembly includes a driving part 3 and a first transmission part 4. The driving part 3 can drive the first transmission part 4 to slide. The first transmission part 4 is connected to the first pipe column 1 and the motion assembly 5 respectively.

[0050] More specifically, the driving unit 3 is the source of the driving force, which can generate sufficient force to push the first transmission unit 4 to move by electric, manual or other means. The specific implementation of the driving unit 3 may vary depending on the vehicle type and manufacturer. The first transmission unit 4 usually has a high degree of reliability and durability to ensure stable performance during long-term use. It may use transmission mechanisms such as slide rails, racks, and gears to achieve force transmission and conversion. The connection between the first transmission unit 4 and the first column 1 and the motion component 5 may be bolts, pins, welding, etc. to ensure the firmness and stability of the connection.

[0051] Preferably, a guide member 22 is further included, the guide member 22 is provided on the second pipe column 2, and the guide member 22 is suitable for slidingly cooperating with the first transmission part 4. More specifically, the guide member 22 provides a stable sliding track and support for the first transmission part 4, ensuring that the first transmission part 4 can slide smoothly and accurately, thereby promoting the first pipe column 1 to adjust its height relative to the second pipe column 2.

[0052] Preferably, the guide member 22 is provided with a sliding surface on one side facing the first transmission part 4, and the first transmission part 4 is slidably matched with the sliding surface. Preferably, the guide member 22 includes a first guide member 221 and a second guide member 222, the first guide member 221 is provided with a first groove, the second guide member 222 is provided in the first groove, and the second guide member 222 is provided with a sliding surface. More specifically, the first guide member 221 and the second guide member 222 can be tightly fitted by welding, riveting, solid-melt bonding, etc.

[0053] Preferably, the second guide member 221 is made of elastic material, and is usually made of wear-resistant, corrosion-resistant, and high-strength materials, such as metal or polymer plastic, to ensure that it can maintain stable performance during use.

[0054] like Figure 2 As shown, preferably, the first transmission part 4 includes a fixed part 42, a first connecting part 43 and a second connecting part 41, the first connecting part 43 and the second connecting part 41 are both connected to the fixed part 42, the fixed part 42 is connected to the driving part 3, the first connecting part 43 is connected to the moving component 5, and the second connecting part 41 is connected to the first pipe column 1.

[0055] More specifically, when the driving part 3 generates a driving force, the force is first transmitted to the entire first transmission part 4 through the fixing part 42. Then, part of the driving force is transmitted to the motion component 5 through the first connecting part 43, so that the motion component 5 can decompose part of the force. The remaining driving force is directly transmitted to the first column 1 through the second connecting part 41, pushing the first column 1 to slide relative to the second column 2, so as to achieve the height adjustment of the steering column. During the movement, the sliding fit between the guide member 22 and the first transmission part 4 (especially the second connecting part 41) ensures the smoothness and accuracy of the sliding.

[0056] Preferably, the first connection portion 43 is arranged opposite to the second connection portion 41, and the first component 52 is fixedly connected to the side of the first connection portion 43 facing the second connection portion 41. More specifically, since the first connection portion 43 is arranged opposite to the second connection portion 41, this layout may help provide stable support and precise guidance, ensuring that the height adjustment of the steering column has sufficient accuracy and stability.

[0057] Preferably, the second column 2 is provided with a positioning hole 21, and the second component 52 is fixed to the second column 2 through the positioning hole 21. More specifically, the positioning hole 21 on the second column 2 provides a precise fixing position for the second component 52, and the second component 52 is firmly fixed to the second column 2 through appropriate fasteners. This connection method ensures the stability and reliability of the steering column mechanism and is an important component in the design of the steering column mechanism.

[0058] Preferably, the second component 51 comprises a first connecting hole 511 , and the positioning hole 21 is a threaded hole. The fastener is suitable for passing through the first connecting hole 511 and being threadedly connected to the positioning hole 21 to fix the second component 51 to the second pipe column 2 .

[0059] Preferably, the driving part 3 is fixed to the second pipe string 2, and is used to drive the first pipe string 1 to move axially. The driving part 3 is fixed to the second pipe string 2. This design ensures the stability and reliability of the driving part 3, so that it can more effectively drive the first pipe string 1 to move axially.

[0060] Preferably, the driving part 3 includes a driving motor 32 and a motor screw 31 drivingly connected to the driving motor 32, and the motor screw 31 is fixedly connected to the first transmission part 4. Since the driving part 3 is fixed on the second pipe column 2, and the motor screw 31 is directly connected to the first transmission part 4, this design ensures the stability and reliability of the entire system and reduces the risk of failure caused by loosening or wear of transmission parts.

[0061] The embodiment of the present application also discloses a steering system, which includes a steering wheel and a steering column mechanism as described above, and the reliability and safety of the steering system are improved. The steering column mechanism has a precise and stable adjustment function, and the driving unit drives the first column to move axially relative to the second column, thereby achieving height adjustment of the steering wheel. This design allows the driver to adjust the height of the steering wheel according to his or her own driving habits and height, thereby improving driving comfort and safety.

[0062] The embodiment of the present application also discloses a vehicle, which includes a vehicle body and the steering system as described above. By applying the optimized steering system to the vehicle, the driving comfort and safety of the vehicle can be significantly improved. The driver can adjust the height of the steering wheel according to his own needs, reduce fatigue caused by long-term driving, and thus focus more on the driving process.

[0063] In addition, since the steering system has a high degree of reliability and stability, it can also reduce the safety risks of vehicles caused by steering system failures. This is of great significance to improving the overall performance and safety of the vehicle.

[0064] In summary, the steering system and vehicle disclosed in the embodiments of the present application achieve flexible adjustment of the steering wheel height by adopting an optimized steering column mechanism and a precise adjustment method, thereby improving driving comfort and safety. At the same time, the steering system also has high reliability and stability, reducing the safety risks of the vehicle caused by steering system failure.
