Detailed Implementation

[0022] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. The described embodiments are only some embodiments of this utility model, and not all embodiments.

[0023] Example 1: Refer to Figures 1 to 5 In motorcycle construction, the steering column mounting structure is a crucial component, its design and performance directly impacting the motorcycle's handling stability and driving safety. This article introduces a motorcycle steering column mounting structure that, through meticulous design, effectively enhances the steering column's fixation while considering factors such as lubrication and structural stability, demonstrating superior performance and practicality.

[0024] The motorcycle steering column fixing structure mainly consists of three core components: a first fixing block 4, a second fixing block 5, and a steering column 3. An oil inlet channel 51 is innovatively designed on one side of the second fixing block 5. On both sides of the oil inlet channel 51 are clamping blocks 52 formed by the second fixing block 5 itself. This layout greatly optimizes the compactness of the entire structure and provides a convenient channel for subsequent lubrication operations. The side of the clamping block 52 closest to the steering column 3 is designed as an oil cavity 54. Oil enters the oil cavity 54 through the oil inlet channel 51, forming a lubricating film between the steering column 3 and the fixing block. This effectively reduces the coefficient of friction between them, reduces wear, extends the service life of the steering column, and ensures smooth and fluid steering operations.

[0025] The oil cavity 54 is designed with an arc-shaped structure. This arc-shaped design fully considers the shape and movement trajectory of the steering column 3, allowing the oil cavity to better fit the steering column, thus enabling a more even distribution of oil during lubrication and further enhancing the lubrication effect. Simultaneously, an oil cavity slot 56 is provided between the oil injection channel 51 and the oil cavity 54. The presence of the oil cavity slot 56 plays an important role in buffering and guiding. When oil flows in from the oil injection channel 51, the oil cavity slot 56 guides the oil to enter the oil cavity 54 more evenly, avoiding direct impact of the oil on the bottom of the oil cavity and causing excessive local pressure, thereby ensuring the stability and reliability of the entire lubrication system.

[0026] A sliding portion 53 is provided on one side of the clamping block 52, which plays a crucial role when the steering column 3 rotates. When the motorcycle is steering, the sliding portions 53 on both sides of the first fixing block 4 and the second fixing block 5 rotate relative to the steering column 3. This design allows the fixing blocks to maintain a stable clamping force during the rotation of the steering column, while the sliding portion reduces dry friction between the fixing blocks and the steering column, further reducing wear and improving the durability and reliability of the entire structure.

[0027] For the material selection of the sliding part 53, nylon was chosen as the preferred option. Nylon has many excellent properties. First, it has a low coefficient of friction, which reduces the friction between the sliding part and the steering column when the steering column rotates, making steering easier and less strenuous, thus improving the motorcycle's handling performance. Second, nylon has good wear resistance, resisting wear during long-term use and extending the service life of the sliding part, thereby reducing the frequency of maintenance and replacement and lowering operating costs. In addition, nylon also has a certain degree of self-lubricating properties, which to some extent compensates for potential deficiencies in the lubrication system, further enhancing the stability and reliability of the entire steering column fixing structure under different operating conditions.

[0028] On the side of the clamping block 52 near the oil chamber 54, there is a concave portion 55. This concave portion 55, in conjunction with the arc-shaped structure of the oil chamber 54, forms a more compact and efficient lubrication space. The concave portion 55 can better guide the oil to form a stable lubricating film on the steering column surface. At the same time, during the rotation of the steering column, the shape of the concave portion helps to maintain the adhesion of the oil, further improving the lubrication effect, reducing the energy loss of the steering column during rotation, and enabling the motorcycle's steering system to operate more efficiently.

[0029] For the connection and fixation of the first fixing block 4 and the second fixing block 5, fasteners 8 are used for connection, and connecting plates 6 are used to fix the fasteners 8 together. This connection method not only ensures a tight connection between the fixing blocks, which can withstand various bumps and vibrations during motorcycle operation, but also provides good structural stability. The design of the connecting plate 6 further enhances the integrity and rigidity of the entire fixing structure, enabling it to better resist external impacts and protect the steering column from damage. In addition, lower positioning plates 62 and side positioning plates 63 are provided at both ends of the connecting plate 6. These two positioning plates hold the edges of the fasteners 8, thereby effectively preventing the fasteners 8 from rotating or loosening during use. In this way, the reliability of the entire fixing structure is greatly improved, ensuring the steering column fixation effect of the motorcycle during long-term use and providing the driver with a stable and reliable handling experience.

[0030] The edges of the first fixing block 4 and the second fixing block 5 are designed as curved edges 7. The curved edge 7 design has several advantages. On the one hand, it can reduce the space occupied by the fixing blocks during installation and disassembly, making it easier for operators to carry out maintenance and repair. On the other hand, the curved edge can avoid sharp corners from interfering with or colliding with other components during use, reducing the risk of damage, and also making the entire fixing structure more streamlined and aesthetically pleasing.

[0031] Example 2: Refer to Figures 1 to 5The motorcycle steering column fixing structure mainly consists of three core components: a first fixing block 4, a second fixing block 5, and a steering column 3. An oil inlet channel 51 is provided on one side of the second fixing block 5; this design is a stroke of genius and highly innovative. On both sides of the oil inlet channel 51 are clamping blocks 52 formed by the second fixing block 5 itself. This layout cleverly optimizes the compactness of the entire structure, allowing all components to be arranged closely and orderly, saving space, and providing a convenient channel for subsequent lubrication operations, facilitating the injection and distribution of lubricating oil. The side of the clamping block 52 closest to the steering column 3 is designed as an oil cavity 54, into which oil enters through the oil inlet channel 51. Once the oil fills into the oil cavity 54, a uniform lubricating film is formed between the steering column 3 and the fixing block. This lubricating film acts like a soft protective pad, effectively reducing the coefficient of friction between the two components and minimizing wear caused by friction. This significantly extends the service life of the steering column and ensures smooth and fluid steering operation, allowing the driver to experience lighter and more precise steering feedback when operating the motorcycle, thus improving driving comfort and safety.

[0032] Furthermore, as a preferred design, the oil cavity 54 is cleverly designed as an arc-shaped structure. This arc-shaped structure fully considers the shape and movement trajectory of the steering column 3, allowing the oil cavity to closely fit the surface of the steering column. During lubrication, the oil can be distributed more evenly, avoiding oil accumulation or uneven distribution in local areas, thus further enhancing the lubrication effect. Regardless of the steering column's rotation angle, the arc-shaped oil cavity ensures that the lubricating oil fully covers its surface, providing all-round lubrication protection for the steering column. Simultaneously, an oil cavity slot 56 is provided between the oil inlet channel 51 and the oil cavity 54. The presence of the oil cavity slot 56 acts as a delicate buffer device, playing an important role in buffering and guiding flow. When oil flows in from the oil inlet channel 51, the oil cavity slot 56 guides the oil into the oil cavity 54 in a more even and stable manner, avoiding direct impact of the oil on the bottom of the oil cavity and causing excessive local pressure. This ensures the stability and reliability of the entire lubrication system, allowing the lubricating oil to function continuously and stably, providing a lasting guarantee for the smooth rotation of the steering column.

[0033] Furthermore, a sliding portion 53 is provided on one side of the clamping block 52, which plays a crucial role when the steering column 3 rotates. When the motorcycle is steered, the steering column rotates, and the sliding portions 53 on both sides of the first fixing block 4 and the second fixing block 5 rotate relative to the steering column 3. This design allows the fixing blocks to maintain a stable clamping force during the rotation of the steering column, ensuring that the steering column will not loosen or jam due to interference from the fixing blocks, thus guaranteeing the stability and reliability of the steering system. At the same time, the sliding portion greatly reduces the dry friction between the fixing blocks and the steering column. Without lubrication, direct friction between metal parts generates a lot of heat and wear, while the introduction of the sliding portion effectively reduces this friction, further reducing wear and improving the durability and reliability of the entire structure, allowing the steering column fixing structure to maintain good performance during long-term use.

[0034] For the material selection of the sliding part 53, nylon was chosen as the preferred option. This material selection was made after careful consideration and repeated testing. Nylon possesses many excellent properties, making it an ideal material for the sliding part. First, nylon has a low coefficient of friction, which significantly reduces the friction between the sliding part and the steering column when the steering column rotates, making steering easier and less strenuous. The rider only needs to apply a small amount of force to easily complete the steering action, significantly improving the motorcycle's handling performance. Second, nylon has good wear resistance, resisting wear during long-term use. Even under frequent steering operations and certain load conditions, the nylon sliding part can maintain its integrity and performance stability for a long time, extending its service life, thereby reducing the frequency of maintenance and replacement, lowering operating costs, and providing an economical guarantee for the long-term use of the motorcycle. In addition, nylon also has a certain degree of self-lubricating properties, which to some extent compensates for potential deficiencies in the lubrication system. In some special cases, such as insufficient or interrupted lubricating oil supply, the nylon sliding part can still maintain a certain lubrication effect, further enhancing the stability and reliability of the entire steering column fixing structure under different operating conditions, ensuring stable operation of the motorcycle in various complex environments.

[0035] On the side of the clamping block 52 near the oil cavity 54, a concave portion 55 is designed. This concave portion 55, in conjunction with the arc-shaped structure of the oil cavity 54, forms a more compact and efficient lubrication space. The shape of the concave portion 55 matches the surface contour of the steering column, better guiding the oil to form a stable lubricating film on the steering column surface. Guided by the concave portion, the lubricating film can evenly cover the contact area between the steering column and the fixing block, effectively isolating direct contact between metal parts and further improving the lubrication effect. At the same time, during the rotation of the steering column, the shape of the concave portion helps maintain the adhesion of the oil, preventing the oil from being lost due to centrifugal force or gravity, ensuring that the lubricating oil can continuously play a role in key parts, reducing energy loss during the rotation of the steering column, enabling the motorcycle's steering system to operate more efficiently, improving energy utilization efficiency, and reducing the motorcycle's energy consumption.

[0036] For the connection and fixation of the first fixing block 4 and the second fixing block 5, fasteners 8 are used for connection, and connecting plates 6 are used to fix the fasteners 8 together. This connection method is carefully designed and optimized, which not only ensures a tight connection between the fixing blocks and can withstand various bumps and vibrations during the motorcycle's operation, such as the strong vibrations generated when riding on rough mountain roads, and the impact force generated by road undulations during high-speed driving, but also provides good structural stability. The design of the connecting plate 6 further enhances the integrity and rigidity of the entire fixing structure, enabling it to better resist external impact forces and protect the steering column from damage. Even under harsh driving conditions, such as on bumpy off-road tracks or in the event of a collision, the entire fixing structure can still remain stable, ensuring the normal operation of the steering column and providing reliable safety for the driver. In addition, lower positioning plates 62 and side positioning plates 63 are provided at both ends of the connecting plate 6. These two positioning plates hold the edges of the fasteners 8, thereby effectively preventing the fasteners 8 from rotating or loosening during use. This detailed design greatly enhances the reliability of the entire fixing structure, ensuring the steering column remains fixed during long-term use of the motorcycle. It avoids serious consequences such as steering column wobbling, abnormal noise, or even loss of control caused by loose fasteners, providing the driver with a stable and reliable handling experience.

[0037] To further enhance the performance of the entire fixing structure, the edges of the first fixing block 4 and the second fixing block 5 are designed as curved edges 7. The curved edge 7 design reflects meticulous attention to detail and offers several advantages. Firstly, during installation and disassembly, the curved edge reduces the space occupied between the fixing block and other motorcycle components, allowing operators to perform maintenance and repairs more conveniently and quickly without worrying about sharp edges scratching other parts or causing installation difficulties. Secondly, the curved edge prevents sharp edges from interfering with or colliding with other components during use. During motorcycle operation, relative movement between components is inevitable; the curved edge design effectively reduces the risk of collision damage between the fixing block and other components, protecting the integrity of the entire steering system.

[0038] The connecting plate is equipped with an oil injection hole. Lubricating oil enters through the oil injection hole, then flows into the oil channel, and finally into the oil cavity 54, which is designed with an arc-shaped structure. This arc-shaped structure fully considers the shape and movement trajectory of the steering column 3, allowing the oil cavity to better conform to the steering column, thus enabling a more even distribution of oil during lubrication and further enhancing the lubrication effect. Simultaneously, an oil cavity slot 56 is provided between the oil channel 51 and the oil cavity 54. The presence of the oil cavity slot 56 plays an important role in buffering and guiding. When oil flows in from the oil channel 51, the oil cavity slot 56 guides the oil to enter the oil cavity 54 more evenly, avoiding direct impact of the oil on the bottom of the oil cavity and causing excessive local pressure, thereby ensuring the stability and reliability of the entire lubrication system.

[0039] A sliding portion 53 is provided on one side of the clamping block 52, which plays a crucial role when the steering column 3 rotates. When the motorcycle is steering, the sliding portions 53 on both sides of the first fixing block 4 and the second fixing block 5 rotate relative to the steering column 3. This design allows the fixing blocks to maintain a stable clamping force during the rotation of the steering column, while the sliding portion reduces dry friction between the fixing blocks and the steering column, further reducing wear and improving the durability and reliability of the entire structure.

[0040] For the material selection of the sliding part 53, nylon was chosen as the preferred option. Nylon has many excellent properties. First, it has a low coefficient of friction, which reduces the friction between the sliding part and the steering column when the steering column rotates, making steering easier and less strenuous, thus improving the motorcycle's handling performance. Second, nylon has good wear resistance, resisting wear during long-term use and extending the service life of the sliding part, thereby reducing the frequency of maintenance and replacement and lowering operating costs. In addition, nylon also has a certain degree of self-lubricating properties, which to some extent compensates for potential deficiencies in the lubrication system, further enhancing the stability and reliability of the entire steering column fixing structure under different operating conditions.

[0041] On the side of the clamping block 52 near the oil chamber 54, there is a concave portion 55. This concave portion 55, in conjunction with the arc-shaped structure of the oil chamber 54, forms a more compact and efficient lubrication space. The concave portion 55 can better guide the oil to form a stable lubricating film on the steering column surface. At the same time, during the rotation of the steering column, the shape of the concave portion helps to maintain the adhesion of the oil, further improving the lubrication effect, reducing the energy loss of the steering column during rotation, and enabling the motorcycle's steering system to operate more efficiently.

[0042] For the connection and fixation of the first fixing block 4 and the second fixing block 5, fasteners 8 are used for connection, and connecting plates 6 are used to fix the fasteners 8 together. This connection method not only ensures a tight connection between the fixing blocks, which can withstand various bumps and vibrations during motorcycle operation, but also provides good structural stability. The design of the connecting plate 6 further enhances the integrity and rigidity of the entire fixing structure, enabling it to better resist external impacts and protect the steering column from damage. In addition, lower positioning plates 62 and side positioning plates 63 are provided at both ends of the connecting plate 6. These two positioning plates hold the edges of the fasteners 8, thereby effectively preventing the fasteners 8 from rotating or loosening during use. In this way, the reliability of the entire fixing structure is greatly improved, ensuring the steering column fixation effect of the motorcycle during long-term use and providing the driver with a stable and reliable handling experience.

[0043] To further improve the performance of the entire fixing structure, the edges of the first fixing block 4 and the second fixing block 5 are designed as arc-shaped edges 7. The design of the arc-shaped edges 7 has many advantages. On the one hand, it can reduce the space occupied by the fixing blocks during installation and disassembly, making it easier for operators to carry out maintenance and repair. On the other hand, the arc-shaped edges can avoid interference or collision with other components during use, reducing the risk of damage. At the same time, it also makes the entire fixing structure more streamlined and beautiful in appearance, and coordinated with the overall design style of the motorcycle.

[0044] The top of the steering column 3 is connected to the mounting base 2. The mounting base 2 is designed to provide a stable connection platform, ensuring the stability of the steering column within the overall motorcycle structure. Through precision machining, the mounting base 2 fits tightly with the steering column 3, achieving a seamless connection between the two. This connection method not only enhances the structural strength of the steering column but also improves its fatigue resistance under various driving conditions, ensuring the long-term stable operation of the motorcycle's steering system.

[0045] A fixing rod 11 is mounted on the mounting base 2, with handles 1 at both ends of the fixing rod 11. The handles 1 are designed with ergonomic principles in mind, and their surface is specially treated for a good grip and anti-slip properties. Turning the handles 1 precisely rotates the steering column 3 via a mechanical transmission device. This design not only improves the precision and sensitivity of steering operations but also allows the rider to more easily control the motorcycle's direction. Whether commuting daily on city roads or riding off-road in complex road conditions, the rider can enjoy a more stable and smooth driving experience thanks to this ingenious design.

[0046] For those skilled in the art, the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
