Description
Technical Field
[0001] The utility model belongs to the technical field of automobiles, and particularly relates to a steering column anti-pull-off belt structure. Background Art
[0002] With the rapid development of the automobile industry, consumers pay more and more attention to safety and driving comfort when choosing vehicles. Especially in complex and changeable road environments, the stability and reliability of the steering system are directly related to the life safety of drivers and passengers.
[0003] Although the traditional electric steering column and mechanical column are designed with safety in the event of a collision in mind, there is an obvious technical challenge. When a vehicle collides, the column's collapse function can indeed absorb some of the impact force and protect the driver from serious injury. However, under the impact force, the column's mechanical structure and pull-off block will collapse, which will cause the steering wheel to suddenly fall off. This sudden change will bring great insecurity to the driver and may even affect the driver's judgment and reaction ability in an emergency.
[0004] In addition, the instability of the steering column when encountering vibrations can also have a negative impact on the driving feel; since the steering column connects the steering wheel and steering system, if it cannot remain stable in a vibrating environment, it will cause the steering wheel to shake or shift; this will not only reduce the driver's driving experience, but may also affect the vehicle's handling and safety; for example, when driving at high speeds or changing lanes in an emergency, the shaking of the steering wheel may cause the driver to lose control of the vehicle, thereby increasing the risk of accidents. Utility Model Content
[0005] The utility model provides a steering column anti-pull-off belt structure, which aims to solve the problem that although a traditional steering column can absorb impact force to protect the driver during a collision, the sudden falling feeling of the steering wheel during collapse will bring great insecurity to the driver, affecting his judgment and reaction in an emergency situation. In addition, the instability of the steering column under vibration will also cause the steering wheel to shake or deviate, reducing the driving experience and possibly increasing the risk of accidents.
[0006] The utility model is implemented as follows: a steering column anti-pull-off belt structure comprises a steering column; a clamping structure arranged on the outside of the steering column; wherein the clamping structure comprises: a fixing bracket arranged on the outside of the steering column; the fixing bracket is connected to a vehicle frame; a shock-absorbing pad is arranged between the connecting end surfaces of the fixing bracket and the vehicle frame; a plurality of threaded holes are penetrated through the side wall of the fixing bracket; a plurality of threaded holes are threadedly fitted with fastening rods; a plurality of fastening rods are penetrated through one side of the fixing bracket and a fastening ring is arranged; and a flexible pad is arranged on the inner side of a plurality of fastening rings.

[0011] Preferably, a fastening nut is further included, and a fastening nut is threadedly matched with one side of the connecting shaft adjacent to the pull-off block, and a fastening pad is arranged between the fastening nut and the pull-off block.
[0012] Preferably, the anti-slip belt is made of high carbon steel, and its outer surface is covered with an aluminum oxide coating. Compared with the prior art, the embodiment of the present application has the following beneficial effects:
[0013] Firstly, the device ensures a stable connection between the steering column and the fixed bracket when the vehicle encounters a small-scale vibration or a large external force collision during normal driving through the ingenious combination of the injection-molded anti-detachment block and the L-shaped anti-detachment belt; when encountering an external force impact, the pull-off block will collapse, and at the same time the L-shaped anti-detachment belt will tear and generate resistance, causing the collapse force to slowly decrease. This process not only protects the steering column, but also improves the driver's safe driving comfort; the close cooperation between the connecting shaft and the pull-off block, and the unique design of the L-shaped anti-detachment belt and its rectangular groove, together form a system that can absorb impact energy, provide outward support force, and have buffering and adjustment space; this system effectively prevents the displacement or detachment of the steering column, thereby significantly improving the safety and stability of the steering system.
[0014] Secondly: This device cleverly sets a return spring between the fixed bracket and the injection-molded anti-slip block to ensure that the steering column can be quickly reset after being subjected to external force, effectively reducing the resonance and jitter of the system, thereby maintaining the stability of the steering system; in addition, the application of flexible pads and fastening pads not only enhances friction and prevents sliding or movement, but also plays a key role in buffering and shock absorption, further improving driving comfort; the combination of high-carbon steel and alumina coating not only provides the anti-slip belt with excellent strength and hardness, but also significantly improves its wear resistance, thermal stability and corrosion resistance, thereby greatly enhancing the durability and reliability of the steering system.

[0024] The utility model provides a steering column anti-pull-off belt structure, such as Figure 1-6As shown, it includes a steering column 1; a clamping structure arranged on the outside of the steering column 1; wherein the clamping structure includes: a fixing bracket 2 arranged on the outside of the steering column 1; the fixing bracket 2 is connected to the frame; a shock-absorbing pad 3 is arranged between the connecting end faces of the fixing bracket 2 and the frame; a plurality of threaded holes 4 are penetrated through the side wall of the fixing bracket 2; a plurality of threaded holes 4 are threadedly fitted with fastening rods 5; a plurality of fastening rods 5 are penetrated through one side of the fixing bracket 2 and a fastening ring 6 is arranged; and a flexible pad 7 is arranged on the inner side of a plurality of fastening rings 6.
[0025] It should be noted that, although the traditional steering column 1 can absorb the impact force to protect the driver during a collision, the sudden drop of the steering wheel during collapse will bring great insecurity to the driver, affecting his judgment and reaction in an emergency. In addition, the instability of the steering column 1 under vibration will also cause the steering wheel to shake or deviate, reducing the driving experience and possibly increasing the risk of accidents. The present solution ensures the stable connection of the steering column 1 under various road conditions through the cooperation of the injection molded anti-detachment block and the L-shaped anti-detachment belt 8. Even when facing an impact, the force can be slowly released through the collapse of the pull-off block and the resistance mechanism of the L-shaped anti-detachment belt 8 to protect the steering column 1, while improving driving comfort; its unique system structure can absorb impact energy, provide support, and has a buffering and adjustment function, effectively preventing the displacement of the steering column 1, and significantly improving the safety and stability of the steering system; the ingenious setting of the reset spring 13 enables the steering column 1 to be quickly reset, reduce resonance vibration, and maintain system stability; and the application of the flexible pad 7 and the fastening pad 15 further enhances the friction of the system, buffers and reduces shocks, and makes driving more comfortable.
[0026] Specifically, in this embodiment, the present solution mainly includes a steering column 1; a clamping structure arranged outside the steering column 1; a fixing bracket 2 is located outside the steering column 1 and provides a solid support for the steering column 1 by connecting with the vehicle frame; the main purpose of this design is to ensure that the steering column 1 will not be displaced or detached when subjected to external force, thereby maintaining driving stability and safety;
[0027] A shock-absorbing pad 3 is specially arranged between the connecting end surface of the fixing bracket 2 and the frame; the main function of the shock-absorbing pad 3 is to absorb and reduce the influence of the vibration generated during the driving of the vehicle on the steering column 1; by reducing the vibration, not only the driving comfort is improved, but also the service life of the steering column 1 is extended;
[0028] A plurality of threaded holes 4 are formed through the side wall of the fixing bracket 2, and the internal threads of the threaded holes 4 are matched with tightening rods 5; by rotating the tightening rod 5, the tightness of the connection between the fixing bracket 2 and the steering column 1 can be adjusted, thereby ensuring that the connection between the fixing bracket 2 and the steering column 1 is firm and reliable; this design allows the tightness of the connection to be adjusted according to actual needs to adapt to different use environments and requirements;
[0029] In addition, a fastening ring 6 is provided on one side of the fastening rod 5 that passes through the fixed bracket 2, and a flexible pad 7 is provided on the inner side of these fastening rings 6; the main function of the flexible pad 7 is to increase the friction between the fastening ring 6 and the steering column 1 to prevent the steering column 1 from sliding or moving when subjected to external force; this design further enhances the stability of the steering column 1 and ensures driving safety and comfort.
[0030] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a group of anti-slip belts 8 are symmetrically arranged on the outer side of the fixed bracket 2, and the anti-slip belt 8 is designed in an L-shape, wherein the horizontal part of the L-shape is arranged toward the outside, and the vertical part of the L-shape is connected to the fixed bracket 2, and a rectangular groove 9 is provided in the middle position of the connection between the horizontal part and the vertical part of the anti-slip belt 8.
[0031] In this embodiment, when the steering column 1 is subjected to an external force, the transverse portion of the L-shaped anti-slip belt 8 will first feel the effect of this force; since the transverse portion is arranged toward the outside and is firmly connected to the vertical portion, it can effectively provide an outward supporting force to offset part or all of the external force; this design helps to prevent the steering column 1 from moving outward or detaching under the action of an external force;
[0032] At the same time, the rectangular groove 9 provided at the connection between the horizontal part and the vertical part of the L-shaped anti-slip belt 8 not only increases the elasticity or deformation capacity of the anti-slip belt 8, but also allows the anti-slip belt 8 to be gradually straightened when subjected to tension; in this process, the presence of the rectangular groove 9 will produce a slow and continuous resistance, the size of which can be achieved by adjusting the design of the groove 9; this design allows the anti-slip belt 8 to have a certain buffer and adjustment space under the action of external force, thereby further improving its effect of preventing the steering column 1 from being displaced or detached;
[0033] In short, the design of the L-shaped anti-slip belt 8 and the rectangular groove 9 works together to effectively improve the stability of the steering column 1 and ensure driving safety and comfort.
[0034] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the vertical portion of the anti-slip belt 8 connected to the fixing bracket 2 is connected to the fixing bracket 2 by welding.
[0035] In this embodiment, this connection method can ensure that the anti-slip belt 8 can be firmly fixed on the fixed bracket 2 when subjected to external force, providing stable support. At the same time, the high strength and rigidity of the welded connection can also effectively resist the impact and vibration of external forces, further improving the stability and safety of the steering column 1.
[0036] In a further preferred embodiment of the present invention, Figure 1-5 As shown, it also includes a connecting shaft 10, which passes through the fixed bracket 2 and is provided with a pull-out block 11 on one side of the steering column 1. The pull-out block 11 is pre-opened with a reserved hole 12 for the connecting shaft 10 to pass through.
[0037] In this embodiment, the connecting shaft 10 passes through the reserved holes 12 on the fixing bracket 2 and the pull-off block 11, and the steering column 1 is firmly connected to the fixing bracket 2; when the vehicle is driving normally or encounters a small range of vibration, the connecting shaft 10 and the pull-off block 11 jointly bear these forces, and they work together to ensure the stability of the connection between the steering column 1 and the fixing bracket 2, thereby ensuring the normal operation of the steering system;
[0038] However, when the vehicle encounters a large external force or collision, this design allows the connecting shaft 10 to have a certain amount of movement space in the reserved hole 12 on the pull-off block 11; the purpose of this design is to absorb impact energy to a certain extent, reduce the direct impact on the steering column 1, and prevent it from breaking or falling off instantly, thereby improving the safety and stability of the steering system; this buffer mechanism can protect the driver and passengers from potential injuries and ensure that the vehicle can still maintain a certain degree of controllability in an emergency.
[0039] In a further preferred embodiment of the present invention, Figure 1 As shown, a return spring 13 is provided between the fixing bracket 2 and the pull-off block 11 , and a damper is nested inside the return spring 13 .
[0040] In this embodiment, the main function of the return spring 13 is to provide a certain elastic resistance to resist the displacement when the steering column 1 is deflected by an external force; this elastic resistance helps to maintain the stability and accuracy of the steering column 1; when the external force disappears, the return spring 13 will use its stored elastic potential energy to push the steering column 1 and the pull-off block 11 back to their original positions, ensuring the accurate reset and stability of the steering system;
[0041] In addition, the return spring 13 disposed between the fixed bracket 2 and the pull-off block 11 and the damper embedded therein work together to form an effective shock absorption and buffering mechanism; the damper can absorb and dissipate vibration energy during the movement of the return spring 13 through its viscosity, internal friction and other characteristics, reduce the resonance and jitter of the system, and thus further improve the stability and reliability of the steering system;
[0042] This design enables the steering column 1 to remain stable when encountering external force or vibration, and to quickly and accurately return to its original position after the external force disappears; this not only improves driving comfort and controllability, but also helps protect the safety of the driver and passengers, ensuring that they can enjoy a more stable and smooth driving experience during driving.
[0043] In a further preferred embodiment of the present invention, Figure 3 As shown, a fastening nut 14 is also included. The fastening nut 14 is threadedly matched on one side of the connecting shaft 10 adjacent to the pull-off block 11 , and a fastening pad 15 is arranged between the fastening nut 14 and the pull-off block 11 .
[0044] In this embodiment, the fastening pad 15 is arranged between the fastening nut 14 and the pull-off block 11, and its key function is to increase the contact area between the nut and the pull-off block, which can not only effectively disperse the pressure and improve the overall fastening effect, but also play a key buffering and shock absorbing role. When the fastening nut 14 is subjected to rotational force, the nut will move along the direction of the thread by utilizing the bevel characteristics of the thread, thereby achieving a tight connection or loosening with the connecting shaft 10. This design ensures the stability and reliability of the connection, and helps to reduce loosening and damage caused by vibration or impact.
[0045] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the anti-slip belt 8 is made of high carbon steel, and its outer surface is covered with an aluminum oxide coating.
[0046] In this embodiment, high carbon steel as the material of the anti-slip belt 8 provides strength and hardness, while the aluminum oxide coating provides additional protection for the anti-slip belt 8 through its wear resistance, thermal stability and corrosion resistance, making it more durable and reliable. This combination is particularly effective in applications that need to withstand high loads and harsh environments.
[0047] Working principle: First, the fixing bracket 2 is located on the outside of the steering column 1, and provides a solid support for the steering column 1 through a close connection with the vehicle frame. The main purpose of this design is to ensure that the steering column 1 will not be displaced or detached when subjected to external forces, thereby maintaining driving stability and safety.
[0048] A shock-absorbing pad 3 is specially arranged between the connecting end surface of the fixing bracket 2 and the frame; the main function of the shock-absorbing pad 3 is to absorb and reduce the influence of the vibration generated during the driving of the vehicle on the steering column 1; by reducing the vibration, not only the driving comfort is improved, but also the service life of the steering column 1 is extended;
[0049] A plurality of threaded holes 4 are formed through the side wall of the fixing bracket 2, and the internal threads of the threaded holes 4 are matched with tightening rods 5; by rotating the tightening rod 5, the tightness of the connection between the fixing bracket 2 and the steering column 1 can be adjusted, thereby ensuring that the connection between the fixing bracket 2 and the steering column 1 is firm and reliable; this design allows the tightness of the connection to be adjusted according to actual needs to adapt to different use environments and requirements;
[0050] In addition, in order to further enhance the stability of the connection, a fastening ring 6 is provided on one side of the fastening rod 5 penetrating the fixing bracket 2, and a flexible pad 7 is provided on the inner side of the fastening ring 6; the main function of the flexible pad 7 is to increase the friction between the fastening ring 6 and the steering column 1, so as to prevent the steering column 1 from sliding or moving when subjected to external force;
[0051] An L-shaped anti-slip belt 8 is provided at a specific position of the steering column 1; when the steering column 1 is subjected to an external force, the transverse portion of the L-shaped anti-slip belt 8 will first feel the force; since the transverse portion is arranged toward the outside and is firmly connected to the vertical portion, it can effectively provide an outward supporting force to offset part or all of the external force; this design helps prevent the steering column 1 from moving outward or detaching under the action of an external force;
[0052] At the same time, the rectangular groove 9 provided at the connection between the horizontal part and the vertical part of the L-shaped anti-slip belt 8 not only increases the elasticity or deformation capacity of the anti-slip belt 8, but also allows the anti-slip belt 8 to be gradually straightened when subjected to tension; in this process, the presence of the rectangular groove 9 will produce a slow and continuous resistance, the size of which can be achieved by adjusting the design of the groove 9; this design allows the anti-slip belt 8 to have a certain buffer and adjustment space under the action of external force, thereby further improving its effect of preventing the steering column 1 from being displaced or detached;
[0053] In order to firmly connect the steering column 1 with the fixed bracket 2, a special connection method is designed; the connecting shaft 10 passes through the reserved holes 12 on the fixed bracket 2 and the pull-off block 11 to achieve a tight connection between the two; when the vehicle is driving normally or encounters a small range of vibration, the connecting shaft 10 and the pull-off block 11 jointly bear these forces to ensure the stable connection between the steering column 1 and the fixed bracket 2, thereby ensuring the normal operation of the steering system;
[0054] However, when the vehicle encounters a large external force or collision, the design of the connecting shaft 10 allows it to have a certain amount of movement space in the reserved hole 12 on the pull-off block 11; the purpose of this design is to absorb the impact energy to a certain extent, reduce the direct impact on the steering column 1, and prevent it from breaking or falling off instantly, thereby improving the safety and stability of the steering system;
[0055] In order to further improve the stability and reliability of the steering system, the return spring 13 and the damper are nested between the fixed bracket 2 and the pull-off block 11; the main function of the return spring 13 is to provide a certain elastic resistance to resist the displacement when the steering column 1 is deflected by an external force; when the external force disappears, the return spring 13 will use its stored elastic potential energy to push the steering column 1 and the pull-off block 11 back to their original positions to ensure accurate reset of the steering system; and the damper absorbs and dissipates vibration energy during the movement of the return spring 13 through its viscosity, internal friction and other characteristics, thereby reducing the resonance and jitter of the system;
[0056] Finally, in order to ensure the stability and reliability of the connection, a fastening pad 15 is arranged between the fastening nut 14 and the pull-off block 11; this fastening pad 15 not only increases the contact area between the fastening nut 14 and the pull-off block 11, effectively disperses the pressure, and improves the overall fastening effect, but also plays a key buffering and shock-absorbing role; when the fastening nut 14 is subjected to rotational force, the nut will move along the direction of the thread by utilizing the bevel characteristics of the thread, thereby achieving a tight connection or looseness with the connecting shaft 10.
