Description

Technical Field

[0001] The present invention relates to the technical field of composite dampers, and in particular to a composite shock-absorbing damper for an electric vehicle chassis based on shear thickening materials and intelligent control. Background Art

[0002] With the rapid development of the electric vehicle industry, the shock absorption and damping system of the vehicle chassis plays a key role in improving vehicle comfort, driving stability, and safety. Modern electric vehicle chassis design requires that the shock absorption system not only have efficient vibration absorption and energy conversion capabilities, but also meet multiple requirements such as lightweight, compact structure, and intelligent control. In recent years, composite damper technology that combines shear thickening materials with intelligent control has begun to attract widespread attention. This technology can automatically adjust the damping characteristics according to the real-time operating status, thereby better adapting to the vibration and impact requirements under different operating conditions, and promoting the continuous improvement of the overall performance of electric vehicles.

[0003] However, existing shock absorbers used in electric vehicle chassis often suffer from several deficiencies. Traditional dampers often utilize simple mechanical connections for their fixed mounting structure, making it difficult to balance efficient damping with installation safety and longevity. In practical applications, due to their fixed, single structure, they often struggle to effectively protect the protective housing in the event of vibration or impact during operation, making it prone to collision or damage between components. Due to the lack of a flexible adjustment mechanism, current designs struggle to adjust the housing to a semi-open, semi-closed position to improve ventilation and heat dissipation, limiting their adaptability to high temperatures or extreme operating conditions. Conventional designs also lack a comprehensive approach to fixing and interlocking adjustments for the mounting base, protective rubber housing, and buffer springs, resulting in a composite damper's stability degradation over long-term use due to component wear or loose connections. Therefore, we provide a composite shock absorber for electric vehicle chassis based on shear thickening materials and intelligent control. Summary of the Invention

In this way, during actual use, the staff can rotate the connecting rod 16 to allow the external sleeve plate 17 on one side of the connecting rod 16 to rotate along with the connecting rod 16 under the fixation of the bolt 18. During the rotation process, the connecting rod 16 is limited in the protective sleeve ring 15 and will not cause damage to the protective sleeve frame 11, thereby improving its practicality during actual use.

[0041] Example 2

[0042] like Figure 1-4 As shown, a damping mechanism 2 is provided at one end of the connecting rod 16, and the damping mechanism 2 includes a side plate damping frame 21, a mounting frame 22 is provided on the side plate damping frame 21, an adjustment damper 23 is provided in the side plate damping frame 21, a main connecting plate 24 is provided at one end of the adjustment damper 23, a docking plate 25 is provided on one side of one end of the main connecting plate 24, and an adjustment rotating plate 26 is provided on one side of the docking plate 25;

A docking sleeve 38 is provided on the outer surface of one end, an isolation gasket 39 is provided on one end of the docking sleeve 38, an internal damping ring 310 is provided on the side of the isolation gasket 39 away from the docking sleeve 38, a debris protection plate 311 is provided on the outer surface of the insertion rod 37, a docking housing 312 is provided on one side of one end of the insertion rod 37, an outer sleeve frame 313 is provided on the outer surface of the docking housing 312, a mounting plate 314 is provided in the outer sleeve frame 313, and a carbon fiber hole plate 4 is provided in the mounting plate 314;

[0047] One end of the multi-directional adjustment cylinder 32 is docked in the mounting base 31, one end of the protective rubber sleeve 33 is docked between the mounting base 31 and the multi-directional adjustment cylinder 32, the inner surface of the buffer spring 34 is nested in the outer surface of the protective rubber sleeve 33, and the two ends of the buffer spring 34 are respectively welded between the mounting base 31 and the protective cover ring 35. The outer surface of the docking cover shell 36 is nested and docked in the protective cover ring 35. The outer surface of the insertion rod 37 is inserted through the protective cover ring 35 and the docking cover shell 36 is nested in the protective rubber sleeve 33. The inner surface of the docking shell 38 is nested in one end of the insertion rod 37 and docks the insertion rod 37 for protection. The inner surface of 39 is nested in the outer surface of the insertion rod 37 and is located on one side of the docking sleeve 38. The inner surface of the internal damping ring 310 is nested in the outer surface of the insertion rod 37 and is located on the side of the isolation gasket 39 away from the docking sleeve 38. The fragmentation guard 311 is nested for protection on the outer surface of the insertion rod 37. One side of the docking card shell 312 is welded to the insertion rod 37. The inner surface of the outer sleeve card frame 313 is nested in the outer surface of the insertion rod 37 and is welded to the outer surface of the docking card shell 312. The outer surface of the mounting card plate 314 is docked in the docking card shell 312. The four corners of the carbon fiber hole plate 4 are respectively installed in the four mounting card plates 314.

[0048] In this embodiment, a corresponding buffer mechanism 3 is provided on the internal isolation frame 14 in the protective sleeve frame 11. The staff can install the mounting base 31 in the internal isolation frame 14, and then the staff can nest the protective rubber sleeve 33 between the multi-directional adjustment cylinder 32 and the mounting base 31, and install the buffer spring 34 on the outer surface of the protective rubber sleeve 33 for docking with the protective cover ring 35 and the docking cover shell 36. In this way, the insertion rod 37 can be inserted into the protective rubber sleeve 33, which can allow the protective cover ring 35 and the docking cover shell 36 to limit the insertion rod 37, thereby allowing the internal damping ring 310 to perform buffering protection more stably, and one side of the insertion rod 37 can more stably install and fix the carbon fiber hole plate 4 on the automobile chassis through the docking card shell 312 and the outer sleeve card frame 313. Therefore, its stability in actual use is further improved.

[0049] Working principle:

[0050] like Figure 1-7 As shown, when the damper is actually used for chassis and thickening material cushioning and shock absorption, workers can fix the mounting top frame 13 to the vehicle chassis. The mounting top frame 13 is provided with a protective sleeve 11, which is tightly connected to the welded bottom frame 12 to form an effective isolation and protection. This design ensures that during use, workers can rotate the connecting rod 16 so that the external sleeve 17 on one side rotates along with the connecting rod 16 under the fixing action of bolts 18. Because the connecting rod 16 is limited within the protective sleeve ring 15, it will not cause any damage to the protective sleeve 11 during rotation, which greatly improves its durability and safety during actual use.

[0051] To further enhance practicality, a side panel damping frame 21 is installed at one end of the connecting rod 16 and securely fastened to the outer surface of the protective sleeve frame 11 via a mounting bracket 22. This design allows precise position adjustment within the side panel damping frame 21 by adjusting the damper 23, thereby driving the synchronized positional movement of the main connecting plate 24 and the docking plate 25. By adjusting the rotating plate 26, the operator can precisely control the rotation of the connecting rod 16, enabling the external sleeve 17 to operate in either a semi-open or semi-closed state, effectively improving ventilation.

[0052] Furthermore, to further enhance its functionality during use, a buffer mechanism 3 is provided on the internal isolation frame 14 within the protective sleeve frame 11. Workers can secure the mounting base 31 within the internal isolation frame 14 and insert a protective rubber sleeve 33 between the multi-directional adjustment cylinder 32 and the mounting base 31. Next, a buffer spring 34 is mounted on the outer surface of the protective rubber sleeve 33 and docked with the protective cover ring 35 and docking housing 36. This structural design allows the insertion rod 37 to be inserted into the protective rubber sleeve 33, further ensuring that the protective cover ring 35 and docking housing 36 can effectively limit and protect the insertion rod 37, ensuring that the internal damping ring 310 can stably perform its buffering work.

[0053] During installation, one side of the insertion rod 37 secures the mounting plate 314 via the docking clamp 312 and the outer frame 313, thereby firmly mounting the carbon fiber perforated plate 4 and tightly fitting it to the vehicle chassis. This structural design significantly enhances the stability of the damper during actual use, ensuring that the entire system maintains efficient and stable performance over a long period of time.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
