[0008] A further improvement of the technical solution of the utility model is that: a total of six sliding posts are provided, and the six sliding posts are symmetrically arranged at the upper and lower parts of the buffer rubber block.

[0009] A further improvement of the technical solution of the utility model is that exhaust holes are opened inside the buffer rubber block, and the exhaust holes are arranged at equal distances.

[0010] A further improvement of the technical solution of the utility model is that the inner connecting plate is fixedly connected to the side of the mounting frame by using bolts.

[0011] A further improvement of the technical solution of the utility model is that a rubber pad is fixedly connected to the inner side of the limiting column, and the rubber pad is arranged between the lithium battery pack and the limiting column.

[0012] A further improvement of the technical solution of the utility model is that: the position of the fastening bolt corresponds to the limiting column, and the fastening bolt is threadedly connected to the inside of the limiting column.

[0013] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides an anti-collision lithium battery pack, including a mounting frame 1, a lithium battery pack 2 is movably mounted inside the mounting frame 1, four buffer components 3 are fixedly mounted on the outside of the mounting frame 1, and the four buffer components 3 are respectively located on four sides of the outside of the mounting frame 1.

[0024] By providing a mounting frame 1, the lithium battery pack 2 is clamped and installed inside the mounting frame 1 to limit and fix the lithium battery pack 2. The mounting frame 1 can be disassembled along the top thereof, so that the lithium battery pack 2 can be easily fixed, installed and disassembled, and flexibility is improved. At the same time, a buffer component 3 is provided on the outside of the mounting frame 1 to absorb the impact force generated during a collision, and the impact force is buffered and absorbed by the deformation of the buffer component 3, so as to reduce the impact force acting on the lithium battery pack 2 rigidly installed in the mounting frame 1, thereby improving the protection effect on the lithium battery pack 2.

[0025] like Figure 3 As shown, the buffer assembly 3 includes an inner connecting plate 31, the inner connecting plate 31 is movably connected with a sliding column 32, the outer side of the sliding column 32 is fixedly connected with an outer buffer plate 33, the outer side of the sliding column 32 is movably sleeved with a buffer spring 34 located between the inner connecting plate 31 and the outer buffer plate 33, the outer side of the inner connecting plate 31 and the inner side of the outer buffer plate 33 are both fixedly connected with a limiting frame 35, the inner side of the limiting frame 35 is movably connected with a buffer rubber block 36, and the inner side of the sliding column 32 is fixedly connected with a limiting plate 38 located on the inner side of the inner connecting plate 31.

[0026] When the outer buffer plate 33 is hit, the outer buffer plate 33 drives the sliding column 32 inside thereof to move inward, so that the outer buffer plate 33 squeezes the buffer spring 34 between the inner connecting plate 31 and the outer buffer plate 33 for buffering when moving inward, and at the same time, the buffer rubber block 36 between the inner limit frame 35 of the outer buffer plate 33 is squeezed by force, so that the buffer rubber block 36 squeezes the internal air outward along the exhaust hole 37 to generate deformation for buffering, thereby reducing the impact of the collision on the lithium battery pack 2 and ensuring the normal operation of the lithium battery pack 2.

[0027] like Figure 4 As shown, the mounting frame 1 includes a base 11, the four corners of the top of the base 11 are fixedly connected to limiting columns 12, the lithium battery pack 2 is movably clamped between the limiting columns 12, the top of the limiting columns 12 is movably clamped with a top plate 14, and the top of the top plate 14 is movably installed with a fastening bolt 15.

[0028] By clamping the lithium battery pack 2 between the limiting columns 12, the bottom of the lithium battery pack 2 is located on the base 11, and the rubber pad 13 on the inner side of the limiting column 12 is in contact with the lithium battery pack 2 to limit it. The lithium battery pack 2 is fixed by clamping the top plate 14 on the top of the limiting column 12 and using the fastening bolts 15 to pass through the top plate 14 and connect to the inside of the limiting column 12, thereby facilitating the installation and removal of the lithium battery pack 2 and improving the flexibility of use.

[0029] like Figure 3 As shown, there are six sliding posts 32 in total, and the six sliding posts 32 are symmetrically arranged at the upper and lower parts of the buffer rubber block 36 .

[0030] The outer buffer plate 33 is guided by six sliding columns 32 arranged up and down so that the outer buffer plate 33 can move and buffer.

[0031] like Figure 3 As shown, the buffer rubber block 36 is provided with exhaust holes 37 inside, and the exhaust holes 37 are arranged at equal intervals.

[0032] The air in the exhaust hole 37 is squeezed out by the buffer rubber block 36 , so that the buffer rubber block 36 is deformed to absorb energy and reduce the impact on the lithium battery pack 2 .

[0033] like Figure 1 and Figure 2 As shown, the inner connecting plate 31 is fixedly connected to the side surface of the mounting frame body 1 by using bolts.

[0034] The inner connecting plate 31 is installed by using bolts, thereby facilitating the disassembly and maintenance of the buffer assembly 3 .

[0035] like Figure 4 As shown, a rubber pad 13 is fixedly connected to the inner side of the limiting column 12 , and the rubber pad 13 is arranged between the lithium battery pack 2 and the limiting column 12 .

[0036] The rubber pad 13 contacts the lithium battery pack 2 , thereby reducing friction between the lithium battery pack 2 and the mounting frame 1 .

[0037] like Figure 4 As shown, the position of the fastening bolt 15 corresponds to the limiting column 12 , and the fastening bolt 15 is threadedly connected to the inside of the limiting column 12 .

[0038] The top plate 14 and the limiting column 12 are connected and fixed by fastening bolts 15 corresponding to the limiting column 12 and connected inside the limiting column 12 .

[0039] The following is a detailed description of the working principle of the anti-collision lithium battery pack.

[0040] like Figures 1 to 5As shown, the lithium battery pack 2 is clamped between the limiting columns 12 so that the bottom of the lithium battery pack 2 is located on the base 11, and the rubber pad 13 on the inner side of the limiting column 12 contacts the lithium battery pack 2 to limit its position, and the top plate 14 is clamped on the top of the limiting column 12 and connected to the inside of the limiting column 12 by the fastening bolts 15 passing through the top plate 14 to fix the lithium battery pack 2, and the inner connecting plate 31 is connected and fixed to the outer side of the mounting frame 1 by using bolts, and when the outer buffer plate 33 is hit during use, the outer buffer plate 33 drives the sliding column 32 on the inner side thereof to move The inner side moves so that the outer buffer plate 33 squeezes the buffer spring 34 between the inner connecting plate 31 and the outer buffer plate 33 for buffering when moving inward, and at the same time, the buffer rubber block 36 between the inner limit frame 35 of the outer buffer plate 33 is squeezed by force, so that the buffer rubber block 36 squeezes the internal air outward along the exhaust hole 37 to generate deformation for buffering, thereby reducing the impact on the mounting frame 1 and the lithium battery pack 2. The outer buffer plate 33 is pushed to move outward by the buffer rubber block 36 and the buffer spring 34 after deformation. The sliding column 32 moves outward so that the limit plate 38 abuts against the inner side of the inner connecting plate 31.

[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
