[0035] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0036] Reference Figure 1-4, an integrated communication energy storage device, comprising: a shell 1 and a battery module 2 arranged in the shell 1; the battery module 2 includes a plurality of battery cells 21 placed in parallel, and a buffer 3 is arranged between the battery module 2 and the shell 1; a heat conductor 4 is arranged between two adjacent battery cells 21, and the height of the heat conductor 4 is lower than the height of the battery cell 21; a plurality of the battery cells 21 are fixedly connected by a connecting row 22 and connected in series through the connecting row 22. Among them, the battery module 2 is directly composed of battery cells 21, and a heat conductor 4 is arranged between adjacent battery cells 21 to facilitate heat dissipation. It can be understood that in the integrated communication energy storage device, the plurality of battery cells 21 placed in parallel of the battery module 2 are fixedly connected as a whole by the connecting row 22, and the entire battery module 2 is then placed in the shell 1, and a buffer 3 is arranged between the shell 1 and the battery module 2 to further enhance the integrity and stability of the integrated communication energy storage device. The battery cells are directly assembled into an integrated whole, the overall structure is simple, the installation is convenient, the integrated structure reduces the number and types of unnecessary components, the later maintenance is convenient, and the maintenance cost and difficulty are low. The buffer 3 is provided to improve the ability to resist impact and vibration, and the heat conductive member 4 is provided to ensure the overall heat dissipation performance.

[0037] In some embodiments, the heat conductive member 4 is a soft heat conductive strip. Specifically, the heat conductive member 4 is respectively disposed on the upper and lower parts of two adjacent battery cells 21 , and the middle part is a heat dissipation channel for providing heat dissipation.

[0038] The battery cell 21 of the present invention is described by taking a square battery cell as an example. The battery cell 21 has a square structure, and the positive and negative electrodes of the battery cell 21 are located on the top end surface. Of course, the battery cell 21 of the present invention can also be in other shapes, which is not limited here.

[0039] Reference Figure 1 , 2In some embodiments, the shell 1 includes an upper shell 11 and a lower shell 12 located at both ends of the battery cell 21, a front wall 13, a rear wall 14 and two side walls 15 arranged circumferentially around the battery module 2, a protective plate 16 is provided between the front wall 13 and the battery module 2, and both ends of the protective plate 16 are fixedly connected to the two side walls 15, and the protective plate 16 abuts against the battery module 2 through the buffer 3. It can be understood that since other electronic components are provided between the front wall 13 and the battery module 2, the front wall 13 is not in direct contact with the battery module 2. In order to further fix the battery module 2, a protective plate 16 is provided to provide support to limit the battery module 2 from shaking stably inside the shell 1. Specifically, the protective plate 16 is fixed to the two side walls 15 by screws, and is fastened by screws, which is convenient and labor-saving to install, has good connection stability and high safety. Similarly, the upper shell 11, the lower shell 12, the front wall 13, the rear wall 14 and the two side walls 15 of the housing 1 are preferably connected by screws. In some embodiments, the lower shell 12, the rear wall 14 and the two side walls 15 can also be an integrated structure to facilitate processing and production.

[0040] Reference Figure 4 In some embodiments, the connection row 22 has a first connection end 221, a second connection end 222, and a buffer section 223 located between the first connection end 221 and the second connection end 222. The first connection end 221 and the second connection end 222 are respectively connected to the positive and negative electrodes of two adjacent battery cells 21, preferably by welding. During long-term use, the battery cell 21 may expand, thereby exerting a force on one end of the connection row 22. The buffer section 223 is used to provide a buffering effect and improve the fault tolerance during use. Furthermore, the buffer section 223 is a "convex" structure protruding in the direction away from the battery cell. A threaded hole is provided on the "convex" structure for external connection of equipment such as locking voltage or temperature collection. The "convex" structure can form an air-avoiding space in the connection section so that when the bolt passes through, the bolt will not contact the battery cell assembly. In some specific embodiments, there are two threaded holes, one of which is used normally and the other is used as a backup.

[0041] Reference Figure 1 , 2In some embodiments, the buffer 3 includes a first buffer 31 arranged along the circumference of the battery module 2 and a second buffer 32 located at both ends of the battery module 2; the height of the first buffer 31 is lower than the height of the battery, and the two side walls 15, the rear wall 14 and the protective plate 16 are in contact with the battery module 2 through the first buffer 31; the upper shell 11 and the lower shell 12 are in contact with the battery module 2 through the second buffer 32. It should be noted that there are four first buffers 31, which are respectively arranged on the front, back, left and right sides of the battery module 2. In order to improve the heat dissipation performance of the integrated communication energy storage device, the height of the first buffer 31 is lower than the height of the battery cell 21, that is, when the first buffer 31 is arranged on the battery cell 21, there is a heat dissipation cavity for heat dissipation between the battery cell 21 and the shell 1. In addition, the height of the heat conducting member 4 between the battery cell 21 is lower than the height of the battery cell 21, and a gap for heat dissipation is left between the battery cells, and the heat dissipation gap is connected to the radiator, which can further improve the heat dissipation performance. Specifically, the first buffer member 31 is disposed in the middle of the battery cell 21 , so that the front wall 13 , the rear wall 14 and the two side walls 15 provide sufficient support to the battery cell module 2 through the first buffer member 31 , thereby improving the stability of the integrated communication energy storage device.

[0042] Reference Figure 1In some embodiments, the second buffer 32 includes a buffer sheet and / or a buffer strip. It is understandable that the second buffer 32 can be a buffer sheet, which is respectively arranged on the two end surfaces of the battery module 2, and is used to provide a buffering effect for the battery module 2 on the one hand, and is used to isolate the contact between the battery module 2 and the upper and lower shells 12 to prevent short circuit. Of course, the second buffer 32 can also be a buffer sheet and a buffer strip at the same time, so that the buffering performance is better. It is also possible to set only a buffer strip, wherein the number of buffer strips is multiple, and they are arranged at intervals on the two end surfaces of the battery module 2, which can play a buffering role. In addition, the upper shell 11 is separated from the battery module 2 by the buffer strip, which can also prevent short circuit. Preferably, the second buffer 32 between the battery module 2 and the upper shell 11 includes a buffer sheet close to one side of the upper shell 11 and a plurality of buffer strips close to one side of the battery module 2. That is to say, a buffer sheet and a plurality of buffer strips are simultaneously provided between the battery module 2 and the upper shell 11, and only a buffer sheet can be provided between the battery module 2 and the lower shell 12. The buffer sheet is an insulating sheet, and its thickness is much lower than the buffer strip. The positive and negative electrodes of the battery cell unit are distributed on the upper end surface of the battery cell module 2. In order to prevent short circuit, a buffer sheet and a buffer strip are provided to provide double protection. The buffer strip is arranged in the gap between the positive and negative electrodes of the battery cell unit, and the buffer sheet covers the upper part of the buffer strip. Finally, the upper shell 11 is installed by screws. The battery cell assembly is inside the shell 1, and the battery cell assembly and the shell 1 form a stable whole through uniform support from all directions such as top, bottom, left, right, front and back. Since the integrated communication energy storage device of the utility model is almost in a static environment when in use, that is, the integrated communication energy storage device is in a relatively stable environment, such a structure is sufficient to ensure safety and reliability under efficient and stable operation.

[0043] Furthermore, the material of the buffer 3 is EVA foam. Of course, the buffer 3 can also be other materials with buffering effect, which will not be described here. Specifically, the material of the first buffer 31 is EVA foam, the buffer sheet is a PC insulating sheet, and the buffer strip is EVA foam.

[0044] Reference Figure 1 , 2 In some embodiments, a main board 5 is provided on the side of the front wall 13 facing the protection plate 16, and the main board 5 is electrically connected to the battery module 2. Two output terminals 6 are provided on the other side of the front wall 13, one of which is electrically connected to the main board 5, and the other is electrically connected to the battery module 2. It can be understood that the battery main board 5 is accommodated in the housing 1, so that the integrity is better. The main board 5 is fixed on the front wall 13, and the output terminal 6 is provided on the front wall 13. It can be put into use by connecting the output terminal 6, and the operation is extremely convenient.

[0045] Reference Figure 1In some embodiments, in order to facilitate the movement of the integrated communication energy storage device, handles 7 are fixedly provided on the two side walls 15, and the handles 7 face and protrude from the plane where the front wall 13 is located. In other words, the user can lift the integrated communication energy storage device by holding the handles 7, which is convenient for carrying.
