Technical Field

[0001] This utility model relates to the field of battery cell support technology, specifically a lower support for supporting lithium battery cells. Background Technology

[0002] The lithium battery cell underpinning bracket is a key structural component in a battery module or battery pack. It is mainly used to fix, support and protect individual cells. It plays a vital role in the design of the battery system, affecting not only the overall structural strength of the battery, but also thermal management, safety performance and ease of maintenance.

[0003] However, existing lithium battery cell support brackets often place multiple lithium battery cells directly on the bracket during use, resulting in each lithium battery cell being close together. This reduces the safety of lithium battery cell use, affects heat dissipation, and reduces the lifespan of the lithium battery cells. Therefore, we propose a lithium battery cell support bracket to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lower support bracket for supporting lithium battery cells, which solves the problem that each lithium battery cell is placed close together, which reduces the safety of lithium battery cell use, affects the heat dissipation of lithium battery cells, and reduces the service life of lithium battery cells.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a lower support for supporting lithium battery cells, including a storage box, wherein multiple positioning brackets are provided on the bottom surface of the inner cavity of the storage box, and positioning internal thread tubes are fixedly provided on both sides of the middle position of the bottom surface of the inner cavity of the storage box, multiple first through holes are opened on the top surface of the storage box at the edge, and multiple internal thread grooves are opened on both sides of the long side of the top surface of the storage box.

[0006] The storage box has multiple first heat dissipation holes on its four side walls. Each first heat dissipation hole has a heat dissipation component inside its cavity. Each first heat dissipation hole has internal threaded holes on its two side walls for installing the heat dissipation component.

[0007] Preferably, the top surface of the storage box is provided with a clasp on the outside of each of the internal threaded grooves.

[0008] Preferably, the heat dissipation assembly includes a positioning frame disposed in the inner cavity of the first heat dissipation hole, and fixing plates are provided on both sides of the inner cavity side walls of the positioning frame. A heat dissipation fan is disposed in the inner cavity of the positioning frame and outside the fixing plates. The heat dissipation fan is connected to the fixing plates by a first mounting screw.

[0009] The positioning frame has positioning holes on both sides of the inner cavity side walls. Each positioning hole has a second mounting screw in its inner cavity. One end of the second mounting screw is rotatably connected to the inner cavity of the internal threaded hole. One end of the positioning frame has a hollow plate.

[0010] Preferably, a second heat dissipation hole is provided on the bottom surface of the storage box at the position of each of the positioning brackets.

[0013] Preferably, it also includes a heat dissipation copper sheet, which is disposed on the bottom surface of the storage box.

[0014] Beneficial effects

[0015] This utility model provides a lower support bracket for supporting lithium battery cells. Compared with the prior art, it has the following advantages:

[0016] The lower support for supporting lithium battery cells, through the storage box, provides an attachment base for multiple positioning frames and protects the lithium battery cells installed on each positioning frame. The isolation provided by the multiple positioning frames allows for a certain gap between the lithium battery cells, reducing wear and improving airflow. The storage box can be easily connected to the upper support for supporting lithium battery cells via the positioning internal thread tube, the first through hole, and multiple internal thread grooves, thus working together to protect the lithium battery cells. The storage box has multiple first heat dissipation holes on its four side walls, each with a heat dissipation component inside, and internal thread holes for installing the heat dissipation component on both side walls of each first heat dissipation hole.

[0017] Multiple primary heat dissipation holes facilitate communication between the inner cavity of the storage box and the outside environment. Furthermore, the combined effect of multiple heat dissipation components enhances airflow within the storage box, improving the heat dissipation of the lithium battery cells inside. Internal threaded holes allow for the installation and fixation of the heat dissipation components, thereby improving their stability. Claws connect the storage box to the upper support bracket for holding the lithium battery cells, further enhancing the stability of the connection between the storage box and the upper support bracket. Since secondary heat dissipation holes are provided on the bottom surface of the storage box at the location of each positioning bracket, heat from the inner cavity of the storage box can flow downwards, further improving its heat dissipation effect.

At the same time, each first heat dissipation hole 7 has internal threaded holes on its two side walls for installing the heat dissipation component 8. Through the multiple first heat dissipation holes 7, the inner cavity of the storage box 1 can be easily connected to the outside. Under the action of the multiple heat dissipation components 8, the air circulation inside the storage box 1 can be further improved, which improves the heat dissipation effect of the lithium battery cells inside the storage box 1. Through the internal threaded holes, the heat dissipation component 8 can be installed and fixed, thereby improving the stability of the heat dissipation component 8 in use.

[0029] See Figure 1 , Figure 3 The bottom surface of the storage box 1 and at the position of each positioning bracket 2 are provided with a second heat dissipation hole 9, which can facilitate the downward flow of heat from the inner cavity of the storage box 1, thereby improving the heat dissipation effect of the storage box 1.

[0031] See Figure 2 It also includes a heat dissipation copper plate 12, which is set on the bottom surface of the storage box 1 to enhance the heat dissipation effect at the bottom of the storage box 1.

[0032] During operation, the storage box 1 provides an attachment base for multiple positioning frames 2 and protects the lithium battery cells installed on each positioning frame 2. The isolation provided by the multiple positioning frames 2 creates a certain gap between the lithium battery cells, reducing wear and improving airflow. The internal threaded tube 3, the first through hole 4, and multiple internal threaded grooves 5 facilitate connection between the storage box 1 and the upper bracket supporting the lithium battery cells, thus protecting them in conjunction with the storage box 1. Since multiple first heat dissipation holes 7 are provided on the four side walls of the storage box 1, and each first heat dissipation hole 7 has a heat dissipation component 8 inside, and each first heat dissipation hole 7 has two... The side walls are provided with internal threaded holes for installing heat dissipation components 8. Through multiple first heat dissipation holes 7, the inner cavity of the storage box 1 can be easily connected to the outside. Under the action of multiple heat dissipation components 8, the air circulation inside the storage box 1 can be further improved, which improves the heat dissipation effect of the lithium battery cells inside the storage box 1. The heat dissipation components 8 can be installed and fixed through the internal threaded holes, thereby improving the stability of the heat dissipation components 8. Through the claws 6, it can be engaged and connected with the upper bracket for supporting the lithium battery cells, thereby improving the stability of the connection between the storage box 1 and the upper bracket for supporting the lithium battery cells. Since the bottom surface of the storage box 1 and at the position of each positioning bracket 2 are provided with second heat dissipation holes 9, the heat inside the storage box 1 can be easily circulated downward, thereby improving the heat dissipation effect of the storage box 1.

[0034] The storage box 1 can be connected to external devices through multiple connectors 10 and multiple internal threaded tubes 11, thereby enabling the storage box 1 to be installed and fixed, which improves the stability of the storage box 1. Since the heat dissipation copper fins 12 are set on the bottom surface of the storage box 1, the heat dissipation effect at the bottom of the storage box 1 can be enhanced.

[0035] In summary, this device not only creates a certain gap between the individual lithium battery cells, thereby reducing wear between them, but also improves airflow between them, thus enhancing the heat dissipation of the lithium battery cells located inside the storage box.
