[0027] Example

[0028] like Figure 1-10As shown, in this embodiment, a lithium primary battery shelf structure is mainly disclosed, through which a plurality of single cells 8 are combined into an integral battery pack module, which is suitable for the combination of ultra-large lithium primary batteries. Its main structure includes vertically arranged plywood 1, and a top plate 2, a bottom plate 3, a first side plate 4 and a second side plate 5 are connected between adjacent plywood 1. The outer end surface of the outermost plywood 1 is connected to a panel 6, and a circuit board 7 is provided between the panel 6 and the plywood 1. A plurality of single cells 8 electrically connected to the circuit board 7 are evenly arranged between adjacent plywood 1. Adjacent plywood 1 is fastened together by a tie rod 11, and the lower portion of the first side plate 4 is connected to the upper portion of the first side plate 4. A first fan 41 for blowing air inward is provided, and a second fan 21 for extracting air outward is provided at the end of the top plate 2 away from the first fan 41; specifically, at least two plywood 1 are provided, and this embodiment will take three vertically arranged plywood 1 as an example, the panel 6, the top plate 2, the bottom plate 3, the first side plate 4 and the second side plate 5 together form a box structure, and the plywood 1 and the pull rod 11 are the internal skeleton of the box structure, which play a supporting and fixing role, wherein the pull rod 11 can be a bolt, one end of which is clamped in one plywood 1, and the other end is threadedly connected to another adjacent plywood 1, and the pull rod 11 can be set between adjacent plywood 1. There are multiple, to ensure that the single battery 8 between adjacent clamping plates 1 is tightly assembled, the three clamping plates 1 divide the box structure into two layers of space, front and back, each layer of space is evenly installed with a number of single batteries 8 with the same orientation, the single batteries 8 between different layers of space are connected in series, and the outermost two clamping plates 1 are respectively left with a sandwich between the panel 6, the circuit board 7 is fixed in the sandwich, respectively used to electrically connect the positive and negative electrodes of the single battery 8 after collection, that is, to arrange and combine several single batteries 8 into an integral battery pack module, so that the distance between the positive and negative leads of the battery and the pads of the circuit board 7 is the shortest, effectively reducing the electrical The impedance of the connection improves the stability of the electrical connection, reduces the resistance loss, makes the structure more compact, and improves the stability of the structure. It should be noted that each layer of space constitutes a relatively independent ventilation channel. Through the arrangement of the first fan 41 and the second fan 21, the air used for cooling enters the cavity from the lower part of the first side plate 4, and there are gaps between each single battery 8. After the cooling air has fully exchanged heat with each single battery 8, it is discharged from the top plate 2, realizing continuous ventilation and cooling of each single battery 8, ensuring that the temperature difference between each single battery 8 is minimized, and effectively improving the stability and service life of the battery.

[0029] Furthermore, in specific implementation, Figure 3-5As shown in , 10, a positioning hole 12 is opened at the center position of the above-mentioned splint 1 provided in the embodiment of the present invention, and a support sleeve 9 is connected to the positioning hole 12 for positioning all the splints 1 in series; it should be noted that the support sleeve 9 is a hollow circular tube structure, and both ends of the support sleeve 9 are provided with step surfaces, which can be used to clamp the two outer splints 1, so that the width of the overall battery pack module after combination is the same, ensuring the consistency of structural assembly; in addition, one end of the support sleeve 9 is connected to a boss 91 for abutting against the adjacent shelf structure for equal-pitch installation. Specifically, the boss 91 can be made of plastic material, one end of which is inserted into the support sleeve 9 and abutted against the end face of the support sleeve 9 for limiting position, and the other end protrudes outward from the panel 6. When different shelf structures are installed, the boss 91 of one shelf structure is directly abutted against the panel 6 of another adjacent shelf structure to quickly achieve equal-pitch installation.

[0030] Furthermore, in specific implementation, Figure 1 As shown, the above-mentioned second side plate 5 provided in the embodiment of the present invention is an arc-shaped plate that gradually converges toward the second fan 21. It should be noted that the cooling air entering from the first fan 41 impacts the inner wall of the second side plate 5 after heat exchange. Through the guiding effect of the arc-shaped plate, the gas flow direction is effectively controlled, thereby improving the gas circulation efficiency and cooling effect.

[0031] Furthermore, in specific implementation, Figure 1 、 9 As shown in 10, the above-mentioned first side panel 4 provided in the embodiment of the utility model is bolted to the adjacent plywood 1, and the second side panel 5 is slidably engaged between the adjacent plywood 1 through a slot; specifically, a groove is provided on one side of the end face of the plywood 1, and the first side panel 4 is made of a non-metallic material with a certain flexibility, so that the first side panel 4 is slidably engaged in the groove, thereby realizing screw-free fixing of the first side panel 4 and improving the neatness of the appearance.

The ends of the single cells 8 are tightly sleeved in the large-diameter sections and abut against the end faces of the steps for position limiting. The small-diameter section is used to pass through the electrode terminals to achieve series connection of the front and rear single cells 8. In addition, as Figure 7As shown, the stepped hole 13 can also be directly composed of a large diameter section and a small diameter section. The large diameter section is used to fit the end of the single battery 8 to play a role in positioning and fixing. The small diameter section is used to pass through the electrode terminal to play a role in connecting in series. At the same time, the step surface can be raised to abut and limit.

[0033] Furthermore, in specific implementation, Figure 3 As shown, a positive electrode interface 42 and a negative electrode interface 43 are provided on the above-mentioned first side panel 4 provided in an embodiment of the present utility model. The positive electrode interface 42 is electrically connected to the circuit board 7 on the front end surface, and the negative electrode interface 43 is electrically connected to the circuit board 7 on the rear end surface.
