Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery equipment, in particular to a vertical AGV double-layer battery structure which is convenient for installation. Background Technique

[0002] Nowadays, countries are vigorously developing green energy. As a new type of energy, lithium-ion batteries have the advantages of high energy density and power density, high working voltage, light weight, small size, long cycle life, high stability, cleanliness, environmental protection, etc. They have broad prospects in the fields of power batteries, energy storage industries, power sources such as forklift batteries.

[0003] However, the degree of customization in the industry is relatively high, and the sizes of battery compartments required by different customers are inconsistent. Therefore, it is necessary to design different styles of battery boxes according to the size of the battery compartment to meet customer needs, and there will be a situation where the battery box is narrow and high. The existing narrow and high battery box structure has certain disadvantages:

[0004] 1. When the form of opening the cover from above is adopted, the opening area of the cover is too small, which is not convenient for installation and internal wiring of the battery.

[0005] 2. When the form of opening the cover from the side is adopted and the cell module is placed with the side as the bottom, the bottom layer of cells will be squeezed for a long time, and there is a risk of shell breakage and liquid leakage. Content of the Utility Model

[0006] The purpose of the utility model is to provide a vertical AGV double-layer battery structure which is convenient for installation, so as to solve the problems of high production difficulty and easy deformation and breakage of the cells mentioned in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical scheme: A vertical AGV double-layer battery structure which is convenient for installation, comprising a battery box, a battery box cover buckled on the front side of the battery box, electrical components arranged inside the battery box, and a double-layer cell module. The double-layer cell module includes an upper-layer cell module, a lower-layer cell module and a support component. The lower-layer cell module is connected to the bottom wall of the battery box, and the upper-layer cell module is correspondingly arranged above the lower-layer cell module through the support component. Both the upper-layer cell module and the lower-layer cell module include a cell group, end plates arranged on both sides of the cell group, and an aluminum sheet group. The cell group includes a plurality of cell monomers arranged in parallel, and the aluminum sheet group includes series-connected aluminum sheets and ear aluminum sheets arranged on both sides of the series-connected aluminum sheets.

[0008] As can be seen from the above solution, a double-layer battery cell module is installed inside the battery box. By using the upper and lower layers, the pressure of the upper-layer battery cell module on the lower-layer battery cell module is reduced, and the risk of battery cell breakage and liquid leakage is lowered. The support assembly is used to support the upper-layer battery cell module. The series-connected aluminum sheet is used to effectively collect the current generated by the battery and transmit it to the external circuit, and the access aluminum sheet is used to connect the battery cell group to the external circuit, thereby realizing the charging and discharging functions of the battery. By opening the cover from the side, the convenience of battery assembly is increased in the present utility model, which is more convenient for production and installation. Dividing a single battery cell module into a double-layer module reduces the weight of a single battery cell module, which is beneficial to dispersing the pressure of the battery cells, avoiding breakage and liquid leakage caused by long-term extrusion of the lower-layer battery cells, and facilitating installation.

[0009] The end plate includes a connecting plate and a right-angle connecting piece arranged outside the connecting plate. Support blocks are symmetrically arranged on the inner walls of both sides of the battery box, and the right-angle connecting piece is fixedly connected to the support blocks. Thus, it can be seen that the right-angle connecting piece is used to connect with the support blocks on the inner wall of the battery box to realize the fixed connection of the end plate.

[0010] The support assembly includes a battery cell support plate and support rods arranged at the bottom of the battery cell support plate. The upper-layer battery cell module is arranged on the upper surface of the battery cell support plate. Mounting pins are arranged on the support rods, and corresponding jacks are arranged on the battery cell support plate. Thus, it can be seen that the battery cell support plate is used to support the upper-layer battery cell module, and the mounting pins are inserted into the jacks to realize the connection of the support rods at the bottom of the battery cell support plate.

[0011] An interface group connected to the double-layer battery cell module is arranged at the top end of the battery box, and the interface group is connected to the positive and negative electrodes of the battery cell group. Thus, it can be seen that the interface group is used to realize the connection and charging between the external device and the battery.

[0012] Perimeters are arranged on both sides of the opening of the battery box.

[0013] Sheet bodies are elongatedly arranged at both top ends of the battery box, through holes are arranged on the sheet bodies, and handle parts are also arranged on both sides of the top of the battery box. Thus, it can be seen that the handle parts facilitate the handling of the battery box. BRIEF DESCRIPTION OF THE DRAWINGS
