Description

Technical Field

[0001] This utility model relates to a car steering assist device, and more specifically, to a car steering assist apparatus. Background Technology

[0002] Automotive steering assist systems refer to a range of systems and technologies designed to help drivers steer vehicles more easily and accurately. These systems enhance driving safety and comfort by reducing steering wheel effort and improving vehicle handling and stability. With technological advancements, steering assist systems have evolved from early mechanical systems to more advanced forms that integrate electronic technologies and intelligent control systems.

[0003] When a car's steering assist device is in use, the vibration generated by the wheels contacting the ground when the car is driving on a bumpy road is transmitted to the steering wheel through the steering shaft, causing the steering wheel to vibrate. Steering wheel vibration makes it difficult for the driver to maintain stable control of the vehicle, especially in situations requiring precise control (such as high-speed driving or emergency avoidance), which increases the risk of accidents.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a car steering assistance device, which aims to solve the problem of steering wheel vibration caused by vibration when the car is driving on bumpy roads, so as to improve the stability and safety of the driver when precise control is required.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a car steering assist device, including a steering column and a steering wheel, a damper is fixedly installed in the middle of the steering column, a spring is movably placed on the outer surface of the damper, a fixing plate is fixedly installed at the upper and lower parts of the steering column, and two rigid columns are fixedly installed at the lower end of the upper fixing plate, and the rigid columns and the lower fixing plate are movably interlocked.

[0007] The present invention is further configured such that: a rubber pressure block is fixedly installed in the middle of the outer surface of the rigid column, two lubricating oil rings are fixedly installed at the upper end of the lower fixing plate, and an inlet pipe is fixedly installed at the lower end of the lubricating oil rings through a valve.

[0008] The present invention is further configured such that the centerlines of the steering column and the damper coincide.

[0009] The present invention is further configured such that the rubber pressure block is located above the lubricating oil ring.

[0010] In summary, this utility model has the following beneficial effects:

[0011] 1. Using dampers and springs as the main shock absorption components, the damper, as the core shock absorption element, effectively dissipates vibration energy and suppresses excessive vibration of the steering column. The spring, as an elastic element, undergoes elastic deformation when impacted, absorbing some vibration energy. Unlike simple spring damping, in this device, the spring and damper form a parallel structure. When the spring is compressed and wants to rebound, the resistance of the damper will inhibit its rapid rebound, avoiding secondary vibration of the steering column and ensuring smooth steering wheel operation. The combined use of dampers and springs effectively absorbs the vibration transmitted from the wheels to the steering wheel, significantly reducing steering wheel vibration, allowing the driver to maintain stable control of the vehicle on bumpy roads, improving driving stability and safety.

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] A car steering assist device, such as Figures 1 to 2 As shown, the steering column 1 and steering wheel 2 are included. A damper 3 is fixedly installed in the middle of the steering column 1. A spring 4 is movably placed on the outer surface of the damper 3. A fixing plate 5 is fixedly installed on both the upper and lower parts of the steering column 1. Two rigid columns 6 are fixedly installed at the lower end of the upper fixing plate 5. The rigid columns 6 and the lower fixing plate 5 are movably interlocked.

[0020] like Figure 1 As shown, a rubber pressure block 7 is fixedly installed in the middle of the outer surface of the rigid column 6, and two lubricating oil rings 8 are fixedly installed at the upper end of the lower fixing plate 5. The lower end of the lubricating oil rings 8 is fixedly installed with an inlet pipe 9 through a valve.

[0021] like Figure 1 As shown, the center lines of the steering column 1 and the damper 3 coincide. Because the center lines of the steering column 1 and the damper 3 coincide, the balance and stability of the steering assist device are ensured, further improving the vehicle's handling.

[0022] The rubber pressure block 7 is located above the lubricating oil ring 8.

[0023] Working Principle: Shock Absorption Process: When a car is driving on a bumpy road, the vibration generated by the wheels contacting the ground is transmitted upward to the steering wheel 2 through the steering column 1. In order to reduce the impact of this vibration on the driver, this utility model designs a damper 3 and a spring 4 as the main shock absorption components. The damper 3, as the core shock absorption element, is filled with high-viscosity oil and has a piston inside. When the piston of the damper 3 reciprocates in the oil, the oil needs to pass through a small flow-limiting orifice on the piston. According to the principle of fluid mechanics, the oil will generate significant resistance when passing through the narrow channel. This resistance is proportional to the piston's movement speed, thereby effectively consuming vibration energy and suppressing excessive vibration of the steering column. The spring 4, as an elastic element, undergoes elastic deformation when impacted, absorbing part of the vibration energy. Unlike simple spring shock absorption, in this device, the spring 4 and the damper 3 form a parallel structure. When the spring 4 is compressed and wants to rebound, the resistance of the damper 3 will suppress its rapid rebound, avoiding secondary vibration of the steering column 1 and ensuring smooth steering wheel operation.

[0024] Steering Process: Two rigid columns 6 are fixedly installed at the lower end of the upper fixing plate 5. These rigid columns 6 pass through the lower fixing plate 5, forming a movable but stable connection. The upper and lower fixing plates 5 are respectively fixed to the upper and lower parts of the steering column 6, ensuring that the rigid columns 6 can move freely between them while maintaining structural integrity. When the driver turns the steering wheel 2, the upper steering column 1 rotates accordingly. Due to the interlocking connection between the rigid columns 6 and the upper and lower fixing plates 5, the rotation of the upper steering column 1 is directly transmitted to the lower steering column 1 through the rigid columns 6. The rigid columns 6 are made of high-strength alloy steel to ensure sufficient torsional strength. When the rigid columns 6 are compressed by the spring 4... During release, as the rigid column 1 moves up and down, it drives the rubber pressure block 7 to move synchronously, contacting and squeezing the lubricating oil ring 8. The lubricating oil ring 8 has four evenly distributed oil nozzles, each with a diameter of 0.5mm. When the rubber pressure block 7 is pressed downwards, its bottom structure squeezes the oil chamber of the lubricating oil ring 8, causing the internal pressure to instantly rise to 0.8MPa, achieving quantitative oil injection. The lubricating oil ring 8 is made of fluororubber with a Shore hardness of 75A, combining oil resistance and elasticity. A stainless steel spring-loaded one-way valve is installed at the oil nozzle to ensure it only opens during squeezing, maintaining a static pressure of 1.2MPa to effectively prevent lubricating oil leakage. The viscosity grade used is ISO. VG 68 lithium-based grease has a base oil viscosity index of 180, maintaining good lubrication performance in the range of -30℃ to 150℃, ensuring reliable operation across the entire temperature range. The presence of the lubricating oil ring 8 can reduce friction between the rigid column 6 and the fixed plate 5, making the entire system operate more smoothly. At the same time, lubricating oil is replenished through the inlet pipe 9 to maintain the system in good operating condition.

[0025] In summary, the combined use of damper 3 and spring 4 effectively absorbs the vibration transmitted from the wheels to the steering wheel 2, significantly reducing the vibration of the steering wheel 2, enabling the driver to maintain stable control of the vehicle even on bumpy roads, and improving driving stability and safety.

All technical solutions falling within the scope of this utility model's concept are protected.
