Description

Technical Field

[0001] The present invention relates to the technical field of composite dampers, and particularly to a composite shock absorber 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 the overall comfort, driving stability, and safety of the vehicle. The modern electric vehicle chassis design requires that the shock absorption system not only has efficient vibration absorption and energy conversion capabilities, but also needs to meet various requirements such as lightweight, compact structure, and intelligent control. In recent years, the composite damper technology combining shear thickening materials with intelligent regulation has begun to receive wide attention because this type of technology can automatically adjust the damping characteristics according to the real-time working state, thus better adapting to the vibration and shock requirements under different working conditions and promoting the continuous improvement of the overall performance of electric vehicles.

[0003] However, the shock absorption dampers used in the electric vehicle chassis in the prior art often have multiple deficiencies. First, traditional dampers mostly use simple mechanical connection methods in the fixed installation structure, making it difficult to balance the installation safety and service life while ensuring high-efficiency damping. In practical applications, due to the single and fixed structure, once vibration or shock occurs during operation, it is often difficult to effectively protect the protective sleeve frame, and it is easy to cause mutual collision or damage between components. Due to the lack of a flexible adjustment mechanism, the current design is difficult to improve the ventilation and heat dissipation capabilities of the vehicle body through the adjustment of the semi-open and semi-closed state, restricting its adaptability under high-temperature or special working conditions. The fixing and linkage adjustment schemes for the installation base plate, protective rubber sleeve, and buffer spring in the conventional design are not perfect, resulting in the instability of the composite damper during long-term use due to component wear or loose connection. Therefore, we provide a composite shock absorber for an electric vehicle chassis based on shear thickening materials and intelligent control. 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. It should be understood that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection 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, etc. 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 of 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 between a device or feature shown in a figure and other devices or features. It should be understood that 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 figure 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. In the description of the present invention, "a plurality" means two or more, and "several" means one or more, unless otherwise specifically and clearly defined.

The four corners of the carbon fiber hole plate 4 are respectively installed in the four mounting clamp 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 plate 31 in the internal isolation frame 14, and then the staff can nest and install the protective rubber sleeve 33 between the multi-directional adjustment cylinder 32 and the mounting base plate 31, and install the buffer spring 34 on the outer surface of the protective rubber sleeve 33 to dock and install with the protective cover ring 35 and the docking housing 36. In this way, the insertion rod 37 can be inserted into the protective rubber sleeve 33, enabling the protective cover ring 35 and the docking housing 36 to limit and protect the insertion rod 37, so that the internal damping ring 310 can carry out buffer protection work more stably. One side of the insertion rod 37 can more stably install and fix the carbon fiber hole plate 4 on the vehicle chassis through the docking clamp shell 312 and the outer sleeve clamp frame 313, thereby further improving the stability during its actual use.

[0049] Working principle:

[0050] As Figure 1-7 shown, when actually using this damper for buffering and shock absorption between the chassis and the thickening material, the staff can fix the mounting top frame 13 on the vehicle chassis. The mounting top frame 13 is provided with a protective sleeve frame 11 inside, and is closely connected to the welded bottom frame 12 to form an effective isolation and protection. This design ensures that during use, the staff can rotate the series connection rod 16, and the external sleeve plate 17 on one side of it will rotate together with the series connection rod 16 under the fixing action of the bolt 18. Since the series connection rod 16 is limited in the protective sleeve ring 15, it will not cause any damage to the protective sleeve frame 11 when rotating, which greatly improves its durability and safety during actual use.

[0051] To further improve the practicality, a side plate damping frame 21 is installed at one end of the series connection rod 16 and firmly fixed on the outer surface of the protective sleeve frame 11 through the mounting frame 22. This design enables the staff to precisely limit and adjust the damper 23 in the side plate damping frame 21, thereby promoting the main connection plate 24 and the docking plate 25 to perform synchronous limit movement. By adjusting the rotating plate 26, the staff can precisely control the rotation of the series connection rod 16, enabling the external sleeve plate 17 to operate in a semi-open or semi-closed state, effectively improving the ventilation effect.

[0052] In addition, in order to further enhance its functionality during use, a buffer mechanism 3 is provided on the internal isolation frame 14 inside the protective sleeve frame 11. The staff can fix the mounting base plate 31 inside the internal isolation frame 14 and insert a protective rubber sleeve 33 between the multi-directional adjustment cylinder 32 and the mounting base plate 31. Then, a buffer spring 34 is installed on the outer surface of the protective rubber sleeve 33 and is docked and installed with the protective cover ring 35 and the docking cover shell 36. This structural design enables the insertion rod 37 to penetrate into the protective rubber sleeve 33, further ensuring that the protective cover ring 35 and the docking cover shell 36 can effectively limit and protect the insertion rod 37, and ensuring that the internal damping ring 310 stably performs the buffering work.

[0053] During the installation process, one side of the insertion rod 37 fastens the mounting card plate 314 through the docking card shell 312 and the outer sleeve card frame 313, thereby stably installing and closely fitting the carbon fiber hole plate 4 on the vehicle chassis. This structural design significantly enhances the stability of the damper during actual use, ensuring that the entire system can maintain high-efficiency and stable performance for a long time.

Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
