Description

Technical Field

[0001] The present invention relates to the technical field of automotive damping equipment, and particularly to a shear thickening stable damper for an automotive steering system based on shear thickening materials. Background Art

[0002] With the development of automotive electronics and intelligence, the requirements for the stability and handling comfort of modern automotive steering systems are constantly increasing. Especially for high-end passenger cars and new energy vehicles, the feel feedback and damping control during steering directly affect the driving experience and safety performance. Due to the characteristic of adjustable viscosity exhibited by shear thickening materials at different shear rates, they have received extensive attention in the field of automotive vibration reduction and damping in recent years. Applying shear thickening materials to the steering system damper can instantaneously change the internal rheological characteristics according to the driving conditions, achieve more precise damping control, improve the response speed and stability of the steering system, and thus meet the integrated requirements of high-performance vehicles for safety, comfort, and handling.

[0003] However, in actual applications, the existing dampers for automotive steering systems still have problems. Traditional damping devices mostly adopt simple oil or gas damping mechanisms, lacking real-time and refined adjustment of the damping magnitude, and it is difficult to balance the lightness and flexibility during low-speed steering and the stable support during high-speed driving. The existing structures often have relatively large rigidity in the design of the docking and transmission mechanisms, failing to fully utilize the rheological characteristics of shear thickening materials, resulting in non-smooth damping responses when the steering speed or load changes, with jump or delay phenomena. The protection and cooperation design between the outer sheath and the internal transmission parts is relatively single, and wear, leakage, or seal failure are likely to occur during long-term use, thus reducing the durability and reliability of the damper. When multiple components are jointly driven, there is a lack of an efficient limiting and adaptive compensation mechanism, making it difficult for the damper to maintain a consistent adjustment effect under complex working conditions and affecting the overall performance of the steering system. Therefore, we provide a shear thickening stable damper for an automotive steering system using shear thickening materials. Summary of the Invention

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

The specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0031] It should be further noted that the drawings and embodiments of the present invention mainly describe and explain the concept of the present invention. On the basis of this concept, the specific forms and settings of some connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be completely described. However, on the premise that those skilled in the art understand the concept of the present invention, those skilled in the art can implement the above specific forms and settings in a well-known manner.

[0032] When an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0033] The orientation words "inside" and "outside" refer to the inside and outside of the contour of each component itself. The terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0034] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device. For example, if the device in the attached drawing is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways, and corresponding interpretations are made for the spatial relative descriptions used here.

[0035] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0053] Working principle:

[0054] As Figures 1-7 shown, when using this steering gear, the staff can connect the turntable with the docking rod 14 to ensure that one end of the docking rod 14 is connected with the embedded link 13, and the outer surfaces of the embedded link 13 and the docking rod 14 are butted against the mounting base 12. Then, the staff nests the inner surface of the outer protective sleeve 11 in the mounting base 12 and butts one end of the mounting base 12 against the fixed rod 21. The other end of the fixed rod 21 is welded to the adjusting turntable 22. This structural design enables the steering gear to drive the adjusting turntable 22 to perform damping rotation adjustment by driving the docking screw 25 through the controller 29 to control the start of the docking motor 27 during the actual use process. At the same time, the outer protective shell 26 provides protection for the adjusting turntable 22, effectively improving the stability of the system.

[0055] To further improve its practicality during actual use, one end of the fixed rotating rod 21 passes through the adjusting turntable 22 and is connected to the sleeve frame docking rod 31, while the end of the sleeve frame docking rod 31 away from the fixed rotating rod 21 is docked with the meshing ring 34. By nesting and installing the protective sleeve disc 32 and the docking cover disc 33, the functionality of the system is further enhanced. One end of the meshing ring 34 away from the sleeve frame docking rod 31 is jointly driven with the passive docking rod 35, and one end of the passive docking rod 35 is connected to the triangular limit frame 41, and one end of the outer protective tube 42 is connected to the triangular limit frame 41. Then, the outer surface of the embedded fixed rod 43 is nested inside the outer protective tube 42 and is fixed on one side of the triangular limit frame 41.

[0056] To enhance the stability of the adjustment, one end of the first silicone base sleeve 44 is connected to the triangular limit frame 41, on the side away from the outer protective tube 42. One end of the first regulating valve ball seat 45 is welded and installed inside the first silicone base sleeve 44, and the inner surface of the first fixed protective sleeve 46 is nested on the outer surface of the first docking ball rod 47. By connecting one end of the first docking ball rod 47 to the first regulating valve ball seat 45, the staff can precisely adjust the steering gear.

[0057] At the same time, one end of the embedded fixed rod 43 is docked with the extension sleeve 51, and a second silicone base sleeve 52 is installed at one end of the extension sleeve 51. The outer surface of the second regulating valve ball seat 53 is nested inside the second silicone base sleeve 52, one end of the second fixed protective sleeve 54 is connected to the second regulating valve ball seat 53, and the outer surface of the second docking ball rod 55 is nested inside the second fixed protective sleeve 54. Finally, the staff only needs to install two second mounting corner brackets 56 on the first docking ball rod 47 and the second docking ball rod 55 respectively, further simplifying the adjustment process.

[0058] Through the optimization and improvement of these designs, the staff can adjust more easily, significantly enhancing the functionality and practicality of the steering gear during actual use. The precise docking and adjustment of each component make the operation of the steering gear more stable and efficient, thereby enhancing the durability and reliability of the steering gear during long-term use.
