[0025] Please refer to Figures 1-5 , the utility model provides an embodiment: a kind of lithium battery of preventing breakage, including shell 1, the inside of shell 1 is provided with reinforcing mechanism 2;

[0026] Reinforcing mechanism 2 includes installation groove 203, and installation groove 203 is arranged in the inside of shell 1, and second reinforcing rib 202 is uniformly installed in the inside of installation groove 203, and first reinforcing rib 201 is uniformly installed on one side of second reinforcing rib 202.

[0027] First reinforcing rib 201 and second reinforcing rib 202 are all provided with multiple groups, and multiple groups of first reinforcing rib 201 and second reinforcing rib 202 are staggered distribution.

[0028] Specifically, as shown in Figure 1 , when using, by being provided with first reinforcing rib 201 and second reinforcing rib 202, when shell 1 is affected by external force, lithium battery body 5 inside shell 1 can be supported and protected, so as to reduce the influence of external force on lithium battery body 5, and avoid the phenomenon that lithium battery body 5 breaks.

[0029] Lithium battery body 5 is installed in the inside of shell 1, and buffer column 4 is uniformly installed on the outside of lithium battery body 5, damping strip 8 is installed on both sides in the inside of buffer column 4, buffer spring 10 is installed in the inside of buffer column 4, and damping block 9 is installed at the top of buffer spring 10, and connecting column 3 is installed at the top of damping block 9.

[0030] Multiple groups of connecting column 3 are provided, and the material of multiple groups of connecting column 3 is rubber material, and the cross section of multiple groups of connecting column 3 is circular.

[0031] Specifically, as shown in Figure 1 , Figure 2 , Figure 4 And Figure 5 , when using, by being provided with multiple groups of connecting column 3, the force generated by the outside can be further buffered, so as to improve the service life of lithium battery body 5.

[0032] Lithium battery body 5 is installed in the inside of lithium battery body 5, and fire extinguishing mechanism 6 is uniformly arranged in the inside of lithium battery body 5 outside lithium battery body 5.

[0033] Fire extinguishing mechanism 6 includes filling bin 602, and filling bin 602 is arranged in the inside of lithium battery body 5, limit block 604 is installed on both sides in the inside of filling bin 602, and telescopic spring 603 is installed in the inside of filling bin 602, and rubber sealing block 605 is installed at the bottom of telescopic spring 603, and baffle 601 is installed on one side of rubber sealing block 605.

[0034] The filling bin 602 is provided with multiple groups, the cross sections of the multiple groups of filling bins 602 are all rectangular, and the interiors of the multiple groups of filling bins 602 are all filled with liquid carbon dioxide;

[0035] The telescopic springs 603 are provided with multiple groups, the multiple groups of telescopic springs 603 are all in a stretched state in the interiors of the filling bins 602; the limiting blocks 604 are provided with multiple groups, the multiple groups of limiting blocks 604 are distributed at equal intervals, and the materials of the multiple groups of limiting blocks 604 are all polyethylene materials;

[0036] The top end of the shell 1 is provided with a cover plate 11, the bottom end inside the shell 1 and the bottom end of the cover plate 11 are both provided with protective pads 13, the outer side of the top end of the shell 1 is provided with clamping blocks 12, the outer side of the clamping blocks 12 is provided with clamping grooves 14, and the clamping grooves 14 are all arranged in the interior of the cover plate 11;

[0037] Specifically, as shown in Figure 1 、 Figure 3 When in use, the limiting blocks 604 are melted by high temperature, so that the telescopic springs 603 are reset to drive the baffle 601 to make ascending movement, and then the filling bin 602 is in contact with the electric core 7, so that the liquid carbon dioxide in the interior of the filling bin 602 enters between the lithium battery body 5 and the electric core 7, thereby achieving the purpose of extinguishing fire.

[0038] Working principle: when in use, when the shell 1 is subjected to extrusion force from the outside, the second reinforcing ribs 202 and the first reinforcing ribs 201 distributed alternately can disperse the extrusion force, thereby supporting and protecting the lithium battery body 5 in the interior of the shell 1, and then preliminarily relieving the extrusion force from the outside, and in the process of continuous extrusion force, the multiple buffer columns 4 are driven to make descending or ascending movement, thereby driving the multiple damping blocks 9 to make synchronous descending or ascending movement, and the damping blocks 9 make descending or ascending movement at the same time to extrude the buffer springs 10, so that the buffer springs 10 are compressed by the extrusion force, thereby further buffering the extrusion force from the outside, and the damping strips 8 and the damping blocks 9 can inhibit the vibration force when the buffer springs 10 rebound after absorbing the extrusion force, thereby being capable of well protecting the lithium battery body 5, through the above operation, the lithium battery body 5 in the interior of the shell 1 is protected, thereby avoiding the lithium battery body 5 from being affected by the extrusion force from the outside to break, thereby improving the service life of the lithium battery body 5;

[0039] Secondly, when the battery cell 7 inside the lithium battery body 5 catches fire during prolonged use, the internal temperature of the lithium battery body 5 rises. Due to the special material of the limiting block 604, when the internal temperature of the lithium battery body 5 rises to a certain level, the limiting block 604 will melt and decompose. This melting and decomposition of the limiting block 604 will cause the limiting force on the telescopic spring 603 to disappear, thus causing the telescopic spring 603 to reset and pull the baffle 601 and the rubber sealing block 605 to move upward. While the baffle 601 and the rubber sealing block 605 are moving upward, on the one hand, the filling chamber 602 and the battery cell... The obstruction between cells 7 disappears, and on the other hand, it squeezes the liquid carbon dioxide filled inside the filling chamber 602, allowing the liquid carbon dioxide to enter between the lithium battery body 5 and the cell 7. When the liquid carbon dioxide comes into contact with the air between the lithium battery body 5 and the cell 7, it will vaporize. The vaporized carbon dioxide can expel the air and surround the surface of the burning object, reducing the oxygen concentration around the combustible material or in the protected space, thereby producing a suffocating effect and achieving the purpose of extinguishing the fire. Moreover, carbon dioxide is not corrosive and will not damage the internal components while extinguishing the fire. The above operation facilitates the fire extinguishing treatment of cell 7, thereby increasing its service life.
