DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] First embodiment

[0024] Please refer to Figure 1 and Figure 2,in, Figure 1 A structural schematic diagram of a first embodiment of a multifunctional module with fixed end plates on both sides provided by the utility model; Figure 2 for Figure 1 A multifunctional module with fixed end plates on both sides, comprising:

[0025] An end plate body 1, wherein a plurality of honeycomb heat dissipation holes 2 are formed on one side of the end plate body 1, and a plurality of threaded holes 3 are formed between the plurality of honeycomb heat dissipation holes 2;

[0026] A plurality of protrusions 11 are respectively connected to the left and right sides of the surface of the end plate body 1 , and a plurality of threaded mounting holes 10 are provided at the center positions of the two sides of the surface of the end plate body 1 .

[0027] The threaded mounting holes 10 can be opened to install the steel plate. For some situations that exceed the pressure range that the steel strip can withstand, this end plate body 1 can stack the battery cells into groups and keep the module pre-stressed by locking the steel plates to both sides of the end plate body 1.

[0028] A plurality of protrusions 11 are grouped in pairs. The two protrusions 11 can apply a certain amount of pressure to the battery cells when they are stacked in groups, so that the battery cells can perform at their best performance during operation. The multiple groups of protrusions 11 on both sides of the end plate can be used to install steel belts or plastic steel belts to fix the module and maintain pre-pressure on the module when the battery cells are stacked in groups. The protruding parts of the bosses are deliberately shortened to facilitate the installation of the steel belt in consideration of the operability of inserting the steel belt from top to bottom.

[0029] In order to maintain the pre-pressure of the module evenly above and below, this end plate is provided with bumps 11 above and below, and the lower bump 11 is opposite to the upper bump 11, and the protruding part of the lower bump 11 is shortened to facilitate the insertion of the steel belt. After the overall installation of the steel belt is completed and the pressure is released, the battery cell will rebound partially, so the shortened bump 11 below will still play the role of fixing the steel belt, and the steel belt will not fall off due to the shortening of the bump 11.

[0030] The left and right sides and the top of the surface of the end plate body 1 are respectively provided with a first groove 4 and a second groove 6 .

[0031] A second mounting groove 8 and a third mounting groove 9 are formed on the top of the end plate body 1 .

[0032] A first mounting groove 7 is provided on the surface of the end plate body 1 and is located between the second mounting groove 8 and the third mounting groove 9 .

[0033] A mounting through hole 5 is formed at the bottom of the inner wall of the first groove 4 .

[0034] Excessively high temperature will affect the battery life of lithium batteries in large-scale applications such as electric vehicles, grid energy storage, ships, and household energy storage. Therefore, when designing lithium batteries, better heat dissipation capabilities are often pursued. A honeycomb design is adopted on one side of the multifunctional end plate to increase the heat dissipation surface and the heat dissipation area. This design can help the battery cells close to the end plate side to dissipate heat better. In addition, threaded holes can be opened at each honeycomb node on the end plate to facilitate the use of screws to fix parts to the front of the end plate.

[0035] Compared with the related art, the fixed end plates on both sides of the multifunctional module provided by the utility model have the following beneficial effects:

[0036] The utility model provides a multifunctional module with fixed end plates on both sides. A plurality of honeycomb heat dissipation holes 2 are provided on the surface of the end plate main body 1 to eliminate the heat generated when the battery pack is working. At the same time, the end plate main body 1 with a plurality of honeycomb heat dissipation holes 2 and a plurality of threaded holes 3 can generate thrust when the battery core is expanded and squeezed after working for a long time, and the bearing range is increased.

[0040] The adjustment groove 121 is opened on the side of the end plate body 1, and limiting blocks are connected on both sides of the adjustment block 122. Limiting grooves compatible with the two limiting blocks are opened on both sides of the inner wall of the adjustment groove 121. The use of limiting blocks and limiting grooves can prevent the adjustment block 122 from falling off inside the adjustment groove 121.

[0041] A fixing bolt 123 is disposed inside the adjusting block 122 , and a plurality of fixing holes matched with the fixing bolt 123 are formed on the inner wall of the adjusting slot 121 .

[0042] The working principle of the fixed end plates on both sides of a multifunctional module provided by the utility model is as follows:

[0043] When in use, when adjusting the position of the protrusion 11, the adjusting block 122 is driven to move inside the adjusting groove 121 by pulling the protrusion 11. After adjusting the position of the protrusion 11, the fixing bolt 123 is used to pass through the adjusting block 122 and connect with the fixing hole 123 on the inner wall of the adjusting groove 121.
