Description

Technical Field

[0001] The present invention relates to the technical field of battery protection, and in particular to a shear thickening damping device for impact protection of new energy vehicle batteries. Background Art

[0002] With the widespread adoption of new energy vehicles worldwide, the safety and stability of battery systems, as core components of these vehicles, have become a key focus of the industry. Battery packs must not only provide robust power but also withstand the effects of diverse environmental factors. Especially during driving, battery packs are subject to constant impact and vibration. If these external forces are not effectively suppressed, they can adversely affect the battery structure and even pose safety risks. Therefore, improving the battery system's shock and vibration resistance and ensuring its stability under complex driving conditions have become crucial tasks in new energy vehicle design.

[0003] Many existing battery protection solutions lack impact resistance. Common solutions rely primarily on housing structures and simple cushioning materials to mitigate impact loads. However, these traditional protective devices often suffer from short-term protection and insufficient impact resistance. Especially under strong external impacts, existing protective devices cannot effectively implement shear thickening and damping adjustments, resulting in damage to the internal structure of the battery pack, affecting battery life and vehicle safety. Therefore, we provide shear thickening and damping devices for impact protection of new energy vehicle batteries. Summary of the Invention

[0041] Example 2

[0042] like Figure 1-6 As shown, an external connection mechanism 3 is provided between the connecting cover plate 18 and the bottom plate 11, and the external connection mechanism 3 includes a docking plate 31, an outer sleeve 32 is provided at the bottom of the docking plate 31, a snap-on top cone 33 is provided in the outer sleeve 32, a hydraulic rod 34 is provided at one end of the snap-on top cone 33, a hydraulic inner cylinder 35 is provided on the outer surface of the hydraulic rod 34, a threaded adjustment groove 36 is provided on the outer surface of one end of the hydraulic inner cylinder 35, an adjustment outer ring 37 is provided on the outer surface of the threaded adjustment groove 36, and a mounting post 38 is provided at one end of the adjustment outer ring 37;

[0043] The bottom of the docking pad 31 is welded to one end of the outer sleeve 32, the inner surface of the outer sleeve 32 is nested in the outer surface of the buckle top cone 33, one end of the hydraulic rod 34 is welded to the bottom end of the buckle top cone 33, the outer surface of the hydraulic rod 34 is limited in the hydraulic inner cylinder 35 for lifting and lowering adjustment, the inner surface of the outer sleeve 32 is nested in the outer surface of the hydraulic inner cylinder 35, and the threaded adjustment groove 36 on the outer surface of one end of the hydraulic inner cylinder 35 is lifted and lowered in the adjusting outer ring 37 through threaded engagement, one end of the adjusting outer ring 37 is welded to the mounting column 38, and the end of the mounting column 38 away from the adjusting outer ring 37 is welded to the bottom plate 11, and the outer sleeve 32 and the docking pad 31 are interlaced and installed on the docking mounting plate 16.

[0044] In this embodiment, in order to further improve its practicality in actual use, a corresponding external mechanism 3 is provided between the connecting cover plate 18 and the base plate 11. The staff can insert the outer sleeve 32 with the docking pad 31 through the connecting cover plate 18 and then nest the hydraulic cylinder 34 with the snap-on top cone 33 in the outer sleeve 32, and the outer surface of the hydraulic cylinder 34 can be nested in the hydraulic inner cylinder 35 for hydraulic adjustment of lifting and lowering. At the same time, the threaded adjustment groove 36 at one end of the hydraulic inner cylinder 35 can be used to perform threaded lifting and lowering adjustment in the adjusting outer ring 37, and one end of the adjusting outer ring 37 is welded to the base plate 11 through the mounting column 38, so that the damping device can perform auxiliary protection, thereby further improving its practicality in actual use.

[0045] Working principle:

[0046] like Figure 1-6 As shown, when using this protective device to protect new energy vehicle batteries, the staff must first pre-install the damping protection structure in this device inside the protective shell and make it tightly nested in the surface of the battery's external structure. During the installation process, the staff only needs to weld the two sides of the connecting cover 18 to the corresponding positions of the top cover 15 and the shell to form a solid overall protective structure. Subsequently, the staff fixes the threaded docking column 21 and the tooth meshing disk 22 of the embedded mechanism 2 in the threaded embedded plug 17 by means of threaded rotation to achieve reliable installation of the embedded mechanism. At this time, the outer surface of the threaded embedded plug 17 is tightly embedded in the top cover 15, so that the entire embedded mechanism 2 is effectively docked inside the top cover 15.

[0047] After securing the battery, the operator can insert the spring 24 and damping adjustment rod 23 into the lifting guard ring 14. This guard ring 14 can be raised and lowered within the mounting cylinder 12, while its internal damping structure adjusts its cushioning performance, providing dynamic protection for the battery system. Throughout the entire lifting process, the damping adjustment rod and spring work together to provide cushioning and rebound, effectively mitigating the risk of damage to the battery from external impacts.

[0048] The final step of installing the protective device is to weld the entire shell with the connecting cover 18 and fix the welding column 27 to the bottom structure of the new energy vehicle through the set welding base point, thereby completing the basic installation of the entire protective system.

[0049] To further enhance the adaptability and practicality of the protective system in actual use, an external auxiliary mechanism 3 is installed between the connecting cover plate 18 and the base plate 11. During installation, workers insert an outer sleeve 32 with a docking pad 31 through the connecting cover plate 18 and insert a hydraulic cylinder 34 with a snap-on top cone 33 into the outer sleeve 32. The outer surface structure of the hydraulic cylinder 34 can be further nested within a hydraulic inner sleeve 35, forming a stable hydraulic adjustment system. A threaded adjustment groove 36 is installed at one end of the hydraulic inner sleeve 35, allowing for precise threaded adjustment within an outer adjustment ring 37, enabling flexible control of the protective device's lifting position and clamping force.

[0050] One end of the adjustable outer ring 37 is welded to the base plate 11 via a mounting post 38, ensuring the structural integrity of the entire external connection mechanism, capable of withstanding the various vibrations and shocks experienced during daily operation. Ultimately, this damping device not only provides excellent protection, but also significantly enhances its practicality and reliability under various operating conditions and usage environments through its multi-level adjustable structure and hydraulic assistance mechanism, effectively ensuring the safe operation of new energy vehicle batteries.
