DETAILED DESCRIPTION

[0024] Two embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0025] First embodiment:

[0026] Figures 1-4 An anti-vibration lithium battery assembly is shown, comprising a material transfer frame 1, the upper end of which is fitted with a clamping sealing horizontal cover 2, the lower inner wall of the material transfer frame 1 is fixedly connected with a truss bottom strip 3 symmetrically on the front and back sides, the upper end of the truss bottom strip 3 is provided with a base bearing lower layer 4, the upper end of the base bearing lower layer 4 is fixedly connected with a lithium battery assembly body 5, the left and right inner walls of the material transfer frame 1 are fixedly connected with a rotatable outer shaft 7, the inner end of the rotatable outer shaft 7 is rotatably connected with an inner shaft 6, one end of the inner shaft 6 close to the lithium battery assembly body 5 is fixedly connected with a pair of reinforced anti-dropping strips 13, the other end of the two reinforced anti-dropping strips 13 away from the rotatable outer shaft 7 is fixedly connected with a limiting block 8, the left and right inner walls of the material transfer frame 1 are fixedly connected with a pair of abutting spring members 9, one end of the abutting spring members 9 close to the lithium battery assembly body 5 is fixedly connected with a fitting limiting side plate 10, the other end of the fitting limiting side plate 10 close to the limiting block 8 is provided with a plurality of matching arc-shaped grooves 11, and one end of the limiting block 8 close to the lithium battery assembly body 5 is fixedly connected with a matching transverse clamping column 12.

[0027] Figures 1-4 The front and back ends of the fitting limiting side plate 10 are symmetrically fixedly connected with protruding horizontal blocks 16, which are fixedly connected with each other between the abutting spring members 9, the matching transverse clamping column 12 is clamped into the corresponding matching arc-shaped groove 11, the plurality of matching arc-shaped grooves 11 are arranged at equal intervals from top to bottom, the inner end of the base bearing lower layer 4 is provided with a buffer hollow layer 14, the inner side wall of the buffer hollow layer 14 is fixedly connected with a plurality of buffer spring members 15, the two fitting limiting side plates 10 are clamped on the left and right sides of the lithium battery assembly body 5, the front and back corresponding two abutting spring members 9 are respectively located on the front and back sides of the limiting block 8, the upper end of the base bearing lower layer 4 is rectangularly distributed with a plurality of threaded members 17, and the lithium battery assembly body 5 and the truss bottom strip 3 are threadedly connected through the plurality of threaded members 17.

[0028] Figures 1-4The lithium battery assembly body 5 is shown to be in close contact with the left and right side abutting spring members 9 by the elastic abutting force provided by the two abutting spring members 9. The abutting spring members 9 are made of metal materials with good elastic recovery performance, which can adaptively adjust the abutting force according to the size changes of the lithium battery assembly body 5. This design enables the material transfer frame 1 to flexibly adapt to lithium battery assembly bodies 5 of different sizes, greatly improving the versatility of the material transfer frame 1. In actual application scenarios, such as lithium battery production workshops, lithium battery assembly bodies 5 of different models with slight size differences can be stably placed in the material transfer frame 1 through this structure, reducing the cost and complexity of customizing multiple transfer equipment due to component size differences. When storing lithium battery assembly bodies 5 of different sizes in the material transfer frame 1, the inner shaft 6 can be flexibly rotated in the rotatable outer shaft 7. The high-precision bearing connection between the inner shaft 6 and the rotatable outer shaft 7 ensures the smoothness and stability of the rotation process. By rotating the inner shaft 6, the limiting block 8 can be rotated to the corresponding position outside the limiting side plate 10, and matched into the matching arc-shaped slot 11. The design size of the matching arc-shaped slot 11 and the matching transverse clamping column 12 on the limiting block 8 are accurately matched. After the two are clamped, the two reinforcing anti-dropping strips 13 are used to support the two sides of the lithium battery assembly body 5. The reinforcing anti-dropping strips 13 are made of high-strength metal materials with strong bending and tensile resistance. During the transfer process of the lithium battery assembly body 5, this structure can effectively limit the displacement of the lithium battery assembly body 5, ensuring that it remains in a stable state in the material transfer frame 1. Even when subjected to a certain degree of shaking or jolting, the lithium battery assembly body 5 can still be reliably supported and fixed, thereby significantly enhancing its anti-shock performance during the transfer process, reducing the risk of damage to the lithium battery assembly body 5 caused by shaking, and ensuring the quality and safety of the lithium battery assembly body 5. In addition, a layer of anti-slip inner layer 19 is provided in the matching arc-shaped slot 11. The anti-slip inner layer 19 is usually made of rubber or special engineering plastic with high friction coefficient. When the matching transverse clamping column 12 is clamped into the matching arc-shaped slot 11, the anti-slip inner layer 19 is in close contact with the matching transverse clamping column 12. With its high friction characteristics, it effectively increases the friction between the two, making the clamping effect of the matching transverse clamping column 12 more stable and less likely to come loose, further improving the reliability of the entire fixing structure, ensuring that the lithium battery assembly body 5 can be firmly fixed in the material transfer frame 1 in various complex transfer environments.

[0029] Second embodiment:

[0030] Figures 1-4The anti-shock lithium battery assembly is characterized in that the inner side wall matched with the arc-shaped slot 11 is fixedly connected with an anti-skid inner layer 19, the transverse clamping column 12 is matched with the anti-skid inner layer 19, a plurality of buffer spring members 15 are arranged in the base bearing lower layer 4, the buffer spring members 15 are uniformly distributed in the inside of the base bearing lower layer 4, the buffer spring members 15 are made of high-quality spring steel and have good elasticity and durability, when the material transfer frame 1 is subjected to vibration or impact during movement, the buffer spring members 15 can absorb and disperse energy through elastic deformation, thereby providing effective buffering for the placement surface of the lithium battery assembly body 5, which not only protects the lithium battery assembly body 5 from internal structure damage caused by vibration and prolongs the service life of the lithium battery assembly body 5, but also ensures the stability of the lithium battery assembly body 5 during transfer, so that the lithium battery assembly body 5 can always maintain good performance during transportation.

[0031] In combination with the current actual demand, the above-mentioned embodiments adopted by the present application are not limited to the scope, various changes made within the knowledge range of the skilled in the art without departing from the concept of the present application still fall within the protection scope of the present application.
