Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, and in particular to a cylindrical battery pack connection structure. Background Technology

[0002] With increasing global energy scarcity and environmental concerns, electric vehicles have become a key development project for the automotive industries of various countries. However, the main bottleneck in the development of electric vehicles is the battery issue, and the safety and performance of the battery pack are particularly important. The structure for reliably connecting the batteries is also crucial for ensuring stable charging and discharging. Existing battery connection structures are typically single-layered. This method occupies a large area when connecting multiple batteries, leading to a bulky battery pack. Furthermore, with a large unfolded area, loose connections can cause damage.

[0003] Chinese Patent Publication No. CN101399363B, published on April 18, 2012, discloses a battery pack including a positive electrode, a negative electrode, and individual cells. Both the positive and negative electrodes include a guide plate and strip-shaped current collectors extending from the guide plate. Each strip-shaped current collector includes a strip-shaped conductive body and two or more connecting pieces extending from one or both sides of the conductive body. The strip-shaped current collectors of the positive and negative electrodes extend in opposite directions, and two or more individual cells are arranged between the strip-shaped current collectors of the positive and negative electrodes. A drawback of this invention is that the individual cells are arranged in a single layer, which can easily lead to a bulky battery pack. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of the existing technology where the single-cell arrangement is a single-layer structure, which easily leads to a bulky battery pack. It provides a cylindrical battery pack connection structure that allows for layered installation of batteries.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cylindrical battery pack connection structure, comprising:

[0007] The mounting bracket has two mounting brackets, and each mounting bracket has several rows of evenly distributed mounting holes, with adjacent rows of mounting holes staggered.

[0008] A partition panel, with two mounting brackets placed on either side of the partition panel;

[0009] The battery body has several parts, each corresponding to a mounting hole, and the battery body is installed in the mounting hole.

[0010] A conductive plate is used to connect the battery body;

[0011] The conductive strip has its two ends connected to conductive plates on the mounting brackets on both sides.

[0012] The battery cells are installed one-to-one through the mounting holes on the mounting bracket, and the positions of adjacent rows of mounting holes are staggered, which makes the battery cells more compact and reduces the volume occupied by the battery pack. After the cells are installed sequentially on the mounting bracket, the two mounting brackets are installed on both sides of the partition plate. The battery cells on the two mounting brackets are separated by the partition plate, which is made of insulating material. The battery cells on the mounting bracket are connected together by conductive plates to realize the charging and discharging of the battery pack on this mounting bracket. The battery cells on the mounting brackets on both sides of the partition plate are connected by conductive strips to realize the circulation of current. This mounting structure is suitable for the installation of various primary cylindrical batteries, achieving the purpose of layered battery installation.

[0013] Preferably, the mounting frame includes an upper frame and a lower frame, both of which have several mounting holes. The mounting holes on the upper frame correspond one-to-one with those on the lower frame. Connecting rods are mounted on both the upper and lower frames, and the connecting rods have threaded holes that correspond to those on the upper and lower frames. The battery body is placed between the upper and lower frames. By placing the battery body between the upper and lower frames and aligning it with the mounting holes, several battery bodies are connected. The upper and lower frames are fixed by pressing the battery body together. Limiting rings are installed on the side of each mounting hole facing the battery body to limit its position and prevent movement. The upper and lower frames are connected by connecting rods, each with threaded holes. Screws are passed through the threaded holes of the two connecting rods to fix the upper and lower frames together. This design ensures stable installation.

[0014] Preferably, the conductive plate includes a single-row plate and a double-row plate. The single-row plate is installed on the two rows of battery bodies at both ends of the mounting frame, and the remaining battery bodies are connected by the double-row plate. The cross-sectional shape of the double-row plate is a parallelogram. Adjacent rows of battery bodies are connected by the double-row plate. Several connecting pieces are installed on both the single-row plate and the double-row plate. The connecting pieces correspond one-to-one with the battery bodies and are connected to the battery bodies. Conductive plates are provided on both sides of the mounting frame and connected to the battery bodies. One end of the conductive plate is connected to the mounting frame. Single-row conductive plates are placed on both sides of the mounting frame, connecting the battery bodies at the ends together. Then, every other two adjacent rows of battery bodies are connected by double-row plates, dividing the battery bodies into several groups. Each row of battery bodies is then connected together. To achieve a staggered distribution of battery bodies, the double-row plates are arranged in a parallelogram shape to connect the battery bodies. Since the single-row and double-row plates divide the battery bodies into several groups, they are connected one group at a time during installation, enabling rapid connection and reducing interference between battery groups, thus ensuring the stability of the battery pack. The single-row and double-row plates are connected to the ends of the battery bodies via connecting tabs, ensuring reliable connection. The conductive plates installed on both sides of the mounting frame are identical and fixed to the mounting frame with screws, ensuring the stability of the conductive plates. This design guarantees a stable connection.

[0015] Preferably, the mounting hole has several evenly distributed limiting blocks on its circumference. These limiting blocks are connected to the end face of the mounting frame. The double-row plate has several diamond-shaped holes corresponding to the limiting blocks. Several limiting blocks are installed on both sides of the mounting frame, i.e., the end faces of the upper and lower frames. The limiting blocks are evenly distributed circumferentially on the circumference of the mounting hole. At the overlap points covered by the double-row plate, diamond-shaped holes are made in the double-row plate to allow the limiting blocks to pass through. Due to the restriction of the limiting plates, a certain gap exists between the mounting frame and the outer casing or partition plate, which protects the battery body on the mounting frame and prevents damage from contact with the outside. This design protects the battery body.

[0016] Preferably, each of the single-row plates at one end of the mounting frame is equipped with a fixing plate, and a connecting plate is provided on the fixing plate on one side of the mounting frame. One end of the connecting plate is connected to the fixing plate. Both the upper and lower frames of the mounting frame are provided with through holes, and the other end of the connecting plate passes through the through hole at one end of the mounting frame. Both ends of the conductive strip pass through the through holes of the two mounting frames respectively and are connected to the connecting plate. Single-row plates are installed on both sides of the upper end of the mounting frame, and a fixing plate is installed on each single-row plate. The fixing plate is connected to the single-row plate, and the connecting plate installed on the fixing plate passes through the through hole on the mounting frame and places one end between the mounting frames. Then, the fixing plates on the same side of the two mounting frames are connected together by the conductive strip, connecting the battery bodies on the two mounting frames together. The conductive strip also passes through the through hole of the mounting frame, which can protect and limit the conductive strip and prevent the conductive strip from contacting the external structure. This design can connect the mounting frames on both sides.

[0017] Preferably, an electrode plate is provided on the fixing plate on the other side of the mounting bracket. The electrode plate has an L-shaped cross-section, and one side of the electrode plate is connected to the connecting plate. Electrode plates are also installed on the fixing plate on the single-row plate on the other side of the mounting bracket. Electrode plates are installed on both mounting brackets, with one electrode plate on each side being a positive electrode and the other a negative electrode, thereby enabling the normal operation of the battery pack. The motor plate is L-shaped, with one side connected to the connecting plate on the fixing plate and the other side connected to the external structure to realize the charging and discharging of the battery pack. This design enables the charging and discharging of the battery pack.

[0018] Preferably, both the upper and lower shelves are equipped with a bonding plate on the side facing the battery body, and the bonding plate is attached to the side of the battery body. The bonding plate, positioned on the side facing the battery body and attached to it, further protects the battery body on both sides, covering the exposed areas. This design further protects the battery body.

[0019] Preferably, the upper frame of the mounting bracket is equipped with several evenly distributed alignment rods, and the lower frame of the mounting bracket is provided with several evenly distributed alignment holes, with the alignment rods on the upper frame and the alignment holes on the lower frame corresponding to each other. When mounting brackets are placed on both sides of the partition for installation, in order to ensure that the two mounting brackets are aligned, the alignment rod on one side of the mounting bracket is inserted into the alignment hole on the other side of the mounting bracket, ensuring that the mounting brackets are accurately positioned, easy to install, and not easily separated. This design can align the two mounting brackets.

[0020] The beneficial effects of this utility model are: it allows for layered installation of batteries, ensuring stable installation and connection, protecting the battery body, connecting the mounting brackets on both sides, enabling the charging and discharging of the battery pack, further protecting the battery body, and aligning the two mounting brackets.
