However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Examples, such as Figures 1-4 As shown, this utility model provides a high-strength protective shell assembly for lithium batteries, including: a base plate 1, and a plurality of positioning grooves 112, which are opened at the four corners of the top of the base plate 1. A column 101 is slidably connected inside the positioning groove 112. A sliding groove 107 is opened on both sides of the adjacent column 101. A protective plate 103 is slidably connected inside the two sliding grooves 107. Two screws 108 are symmetrically threaded to the other two sides of the adjacent column 101. Limiting holes 109 are opened at the four corners of one side of the protective plate 103. One end of the screw 108 is slidably connected inside the limiting hole 109.

[0026] Furthermore, such as Figures 1-4 As shown, the column 101 is fixedly connected to two other sides adjacent to the bottom of the column 101. The top of each fixed block 110 is symmetrically connected to two locking screws 111. With the above settings, the column 101 can be installed and fixed.

[0027] Furthermore, such as Figures 1-4 As shown, multiple threaded holes 113 are provided at the four corners of the top of the base plate 1, and one end of the locking screw 111 is threaded into the inside of the threaded hole 113.

[0028] Furthermore, such as Figures 1-4 As shown, telescopic rods 201 are fixedly connected to the four corners of one side of the protective plate 103. One end of each telescopic rod 201 is fixedly connected to a buffer plate 2. With the above arrangement, when the buffer plate 2 is subjected to a force, the telescopic rods 201 can retract.

[0029] Furthermore, such as Figures 1-4 As shown, a buffer spring 202 is provided on the outer surface of the telescopic rod 201. The buffer spring 202 is fixedly connected to the buffer plate 2 and the protective plate 103 respectively. Under the elastic force of the buffer spring 202, a certain buffering effect can be achieved, thereby reducing the impact force on the protective plate 103.

[0030] Furthermore, such asFigures 1-4 As shown, the top of the base plate 1 is provided with a top cover 104, the four corners of the top cover 104 are movably connected with a screw rod one 105, the top of the column 101 is provided with a threaded hole one 106, one end of the screw rod one 105 is threadedly connected in the threaded hole one 106, and the top cover 104 can be removed by rotating the screw rod one 105 from the inside of the threaded hole one 106.

The elastic rubber 102 can protect the column 101, and the heat dissipation holes 114 can dissipate heat.

[0032] Working principle: when the buffer plate 2 is impacted, the buffer plate 2 moves to one side of the protective plate 103, the telescopic rod 201 is retracted, and the buffer spring 202 is compressed. The elastic force of the buffer spring 202 can buffer the impact, thereby reducing the impact on the protective plate 103. When the column 101 is impacted, the elastic rubber 102 can buffer the impact, thereby reducing the impact on the column 101. This can reduce the impact on the lithium battery protective shell assembly, thereby avoiding deformation of the protective plate 103 and the column 101, and damage to the lithium battery inside. When one of the protective plates 103 is deformed due to impact, the top cover 104 can be removed by rotating the screw rod one 105 from the inside of the threaded hole one 106. The deformed protective plate 103 can be removed and replaced by rotating the screw rod two 108 from the inside of the limiting hole 109. The limiting of the protective plate 103 can be released. When the column 101 is damaged, the locking screw 111 can be removed from the inside of the threaded hole two 113 by a tool. The limiting of the fixed block 110 can be released. The column 101 can be removed from the positioning groove 112 and replaced. This can replace the damaged part of the lithium battery protective shell assembly, thereby reducing the use cost of the lithium battery protective shell assembly.
