Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile, especially a steering structure for vehicle. BACKGROUND

[0002] In today's automobile industry, consumers' requirements for automobile performance and control experience are increasingly diversified. As a key factor affecting driving convenience and safety, the steering ability of the automobile has always been an important research direction in the field of automobile engineering. While meeting the basic daily driving needs, the limitations of traditional automobile steering structure in specific scenarios are increasingly prominent, prompting the urgent need for research and development of new steering structure.

[0003] In the traditional automobile steering system, whether it is the common rack and pinion type or the recirculating ball type, the basic principle is to realize steering by rotating the wheel around the kingpin. In this way, the car needs to complete the steering action with a large turning radius when turning, and the flexibility is insufficient in narrow spaces. For example, in narrow streets in old urban communities, parking lots with tight parking spaces, drivers need to repeatedly adjust the direction, which is cumbersome and time-consuming to operate, and is also prone to scratches and collisions due to space limitations, increasing the cost and safety risks.

[0004] In addition, the traditional steering structure cannot realize the lateral movement of the automobile. With the rapid increase in the number of urban automobiles, parking spaces are increasingly scarce, and when the vehicles parked on both sides of the parallel parking space are too close, the traditional automobile is difficult to drive in or out, and the "parking difficulty" problem troubles many car owners. At the same time, in some special operation scenarios, such as logistics distribution vehicles in narrow loading and unloading areas, or emergency rescue vehicles in limited spaces that need to quickly adjust their positions, due to the lack of lateral movement capability, the vehicles are difficult to accurately position, delaying the work and rescue opportunity. SUMMARY

[0005] In order to solve the problems in the prior art, the utility model provides a steering structure for vehicle, which has a small turning radius, allowing the automobile to turn freely in a narrow space; it can realize lateral movement function, solve the parking problem, and meet the special operation requirements.

[0007] In the foregoing steering structure for vehicle, the steering drive device includes a driving motor connected with the steering shaft train assembly installed in the first steering piece.

[0008] In the foregoing steering structure for vehicle, the first steering piece includes a transverse section structure, a bent section structure connected with the transverse section structure, and a longitudinal section structure connected with the bent section structure. The first steering piece is made of 3D printing technology or integral casting technology, and is designed as the compact transverse section structure, the bent section structure and the longitudinal section structure, so that different structural sections have different use functions.

[0009] In the foregoing steering structure for vehicle, a cavity groove is arranged in the transverse section structure, and the steering shaft train assembly is arranged in the cavity groove. The cavity groove is used for limiting the installation of the steering shaft train assembly.

[0010] In the foregoing steering structure for vehicle, at least four mounting holes are arranged on the longitudinal section structure, and the mounting holes are circular, square, rectangular or triangular. The mounting holes are used for bolt mounting the first steering piece on an axle.

[0011] In the foregoing steering structure for vehicle, the first cover plate is arranged between the steering drive device and the first steering piece.

[0012] In the foregoing steering structure for vehicle, a gasket plate is further arranged between the steering drive device and the first cover plate.

[0013] In the foregoing steering structure for vehicle, the steering structure for vehicle further includes a mounting assembly, the mounting assembly includes a screw rod, a first shaft sleeve, a second shaft sleeve and a gasket arranged in sequence from top to bottom, and the second steering piece is connected with the steering shaft train assembly installed in the first steering piece through the mounting assembly.

[0014] In the vehicle steering structure as described above, the second steering member comprises a shaft group connecting portion and a wheel mounting portion, and a through groove is provided at the bottom end of the wheel mounting portion.

[0015] In the vehicle steering structure as described above, a hub motor device is further provided, and the hub motor device is mounted in the through groove through a second sealing plate.

[0016] The vehicle steering structure has the following beneficial effects:

[0017] 1. The space utilization efficiency is significantly improved: the turning radius of the vehicle can be greatly reduced; and the vehicle equipped with the vehicle steering structure can easily complete the in-place steering and U-turn operations in the space-limited areas such as narrow streets and crowded parking lots in cities.

[0018] 2. The parking problem is effectively solved: the vehicle is endowed with the lateral movement capability, and the traditional parking method is completely changed. In the face of parallel parking spaces with narrow distance between the two vehicles, the vehicle can be laterally translated into the parking space without relying on a large longitudinal space for diagonal reversing.

[0019] 3. The operation efficiency in special scenarios is improved: the steering structure has obvious advantages in special fields such as logistics distribution and emergency rescue. The logistics distribution vehicle can accurately move laterally to the cargo loading and unloading position in a narrow loading and unloading area, thereby reducing the cargo handling distance and time and improving the logistics efficiency; and the emergency rescue vehicle can quickly adjust the vehicle body position in the accident scene or narrow channel, quickly reach the rescue site, save valuable time for rescue work, and save more lives and property.

[0020] 4. The driving safety is enhanced: the smaller turning radius makes the vehicle more flexible and stable during steering, and reduces the collision risk caused by untimely steering. The lateral movement function enables the vehicle to quickly avoid danger laterally in an emergency, such as avoiding a front obstacle by lateral translation, thereby avoiding a head-on collision. According to simulation tests, the accident rate of the vehicle equipped with the steering structure in an emergency is reduced by about 30% compared with a conventional vehicle, thereby significantly improving the driving safety.

[0021] 5. The design and application boundaries of the vehicle are widened: the innovative steering structure brings a new idea for vehicle design, and vehicle manufacturers can design more compact and reasonable space layout vehicle models based on the steering structure to meet different consumer needs. Meanwhile, in the automatic driving field, the steering structure combined with automatic driving technology can make the vehicle more accurate and efficient in autonomous driving and parking in complex environments, thereby promoting the development of the automotive industry towards intelligence and convenience.
