The oil pipe assembly body 2 is responsible for transmitting fuel to ensure the normal operation of the engine. Through reasonable pipeline design, the resistance in the fuel transmission process is reduced and the fuel efficiency is improved. The buffer sleeve 3 is made of rubber, silicone or polymer composite materials, and has good elasticity and impact resistance. Wrapped around the bends and joints of the main body of the oil pipe assembly, it effectively buffers external impact forces, prevents the oil pipe from being damaged due to vibration or impact, and ensures the safety and stability of fuel transmission. When the vehicle collides or hits, the anti-collision component reduces the impact of the impact force on the main body of the oil pipe assembly through the action of the energy-absorbing part 5 and the impact-resistant shell 6, thereby improving the safety of the vehicle. The anti-collision bracket 4 serves as the supporting structure of the anti-collision component to ensure the correct installation and positioning of components such as the energy-absorbing part 5 and the impact-resistant shell 6. The energy-absorbing part 5 adopts the structure of a damping rod and a connecting spring, which can effectively absorb and disperse the impact energy. When a collision occurs, the impact energy is absorbed through the deformation and rebound of the damping rod and the spring, thereby reducing the impact on the main body of the oil pipe assembly. The first energy-absorbing damping rod 8 and the ... The second energy-absorbing damping rod 9 has good energy-absorbing performance and can absorb a large amount of energy during the impact process. As the main component of the energy-absorbing member 5, it converts the impact energy into heat energy or other forms of energy through its own deformation and rebound, thereby protecting the main body of the oil pipe assembly from damage.

The fastener 7 can firmly connect the connecting seat and the anti-collision component, ensuring a stable connection between the anti-collision component and the main body of the oil pipe assembly, and preventing loosening or falling off during vehicle operation.
[0015] like Figure 1 As shown, on the basis of the above method, the limiting device includes a stop block 11, a limiting ring 12, a wear-resistant gasket 13 and a guide sleeve 14. The stop block 11 is arranged to fit on the side of the second energy absorbing damping rod 9, the limiting ring 12 is arranged at both ends of the stop block 11, the wear-resistant gasket 13 is arranged between the contact surface of the stop block 11 and the second energy absorbing damping rod 9, and the guide sleeve 14 is wrapped around the outside of the second energy absorbing damping rod 9. In implementation, the stop block 11 fits tightly on the side of the second energy absorbing damping rod 9, ensuring that the contact area between the two is maximized, thereby enhancing the limiting effect. By fitting on the side of the damping rod, the stop block 11 is effective The second energy absorbing damping rod 9 is prevented from excessive displacement when impacted, thereby maintaining the stability of its energy absorbing effect. The limit rings 12 are installed at both ends of the stop block 11 to provide additional support for the stop block 1. The limit rings 12 can also effectively prevent the stop block from falling off or shifting when subjected to external force, thereby ensuring the long-term reliability of the limit device. The wear-resistant gasket 13 is arranged between the contact surface of the stop block 11 and the second energy absorbing damping rod 9, thereby reducing the friction and wear between the two. The guide sleeve 14 is wrapped around the outside of the second energy absorbing damping rod 9, thereby providing a clear guide for the movement of the damping rod, thereby ensuring its stability during the energy absorption process.
[0016] like Figure 1 As shown, on the basis of the above method, a sensing element 15 is further provided on the second energy absorbing damping rod 9 for monitoring the extension and retraction distance of the second energy absorbing damping rod and the impact force parameters during the energy absorption process, and transmitting these data to the vehicle control system so as to timely diagnose potential problems or trigger warning prompts.

[0018] like Figure 1 As shown, on the basis of the above method, the buffer sleeve 3 is made of rubber, silicone or polymer composite material, wrapped in the bends and joints of the main body of the oil pipe assembly.

The buffer sleeve 3 is wrapped around the bends and joints of the oil pipe assembly body 2 to play a preventive protective role to prevent damage to the oil pipe due to vibration or small impact. When the vehicle collides or hits, the impact-resistant shell 6 first bears the external impact force.

The connecting spring 10 also plays a role in this process. It has good resilience and durability and can maintain stable performance in multiple impacts. In addition, the limit device also plays a key role. The stop block 11 fits tightly on the side of the second energy absorbing damping rod 9, effectively preventing the second energy absorbing damping rod 9 from excessive displacement when impacted. The limit ring 12, the wear-resistant gasket 13 and the guide sleeve 14 also play their respective functions, enhancing the stability and reliability of the limit device. The sensing element 15 set on the second energy absorbing damping rod 9 can monitor the telescopic distance of the second energy absorbing damping rod and the impact force parameters during the energy absorption process, and transmit these data to the vehicle control system. In this way, the vehicle control system can timely diagnose potential problems or trigger warning prompts based on real-time data, thereby improving the safety and reliability of the vehicle. During the entire working process, the connecting seat 1 plays the role of a bridge. It is sturdy in design and can stably connect the oil pipe assembly body 2 and the anti-collision component to ensure the stability and safety of the oil pipe during vehicle operation. The dedicated fixing seat 16 provides stable support and fixation for the anti-collision bracket 4. In summary, the novel automobile oil pipe assembly with an impact-resistant buffer structure can effectively protect the main body of the oil pipe assembly when the vehicle collides or hits through its unique design and the coordinated work of components, reduce the impact of the impact force on the oil pipe, and improve the safety of the vehicle.
