Description

Technical Field

[0001] This utility model relates to the technical field of battery plastic frame components, specifically a crack-resistant battery plastic component. Background Technology

[0002] A lithium battery module typically consists of a housing containing multiple battery cells. The positive and negative terminals of each cell are set according to the output specifications, and the cells are connected via flexible connecting wires. The flexible connecting wires are then soldered to the output conductive posts on the housing, and the entire lithium battery module outputs power through the conductive terminals on the conductive posts.

[0003] Battery plastic parts are used to assemble battery cells to form lithium battery modules. Traditional battery plastic parts generally use bolts and fixing strips to fix the battery cells. Although this achieves the purpose of fixing the battery cells, it is inconvenient for later disassembly, replacement and maintenance. Therefore, we provide a crack-resistant battery plastic part. Utility Model Content

[0013] Optionally, the side wall of the protective cover has a perforated strip, which allows airflow exchange for the heat dissipation component. The heat dissipation component includes a heat dissipation fan installed inside the protective cover. When the overall temperature of the battery module rises, the heat dissipation fan starts to draw airflow from the outside into the protective cover, while the heat dissipation fan on the other side draws airflow out of the protective cover, thereby achieving airflow convergence and heat dissipation.

[0014] Optionally, the sidewall of the battery rack has multiple through slots. These through slots are used to reduce the weight of the battery rack while allowing airflow. The presence of these through slots facilitates better airflow and achieves better heat dissipation.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a crack-resistant battery plastic component, including a plastic bottom shell 1 and a plastic top shell 2, which are detachably connected by bolts 3, and further includes:

[0028] The protective cover 4 is attached to the inner wall of the plastic bottom shell 1 to protect the battery;

[0029] The heat dissipation component 5 is connected inside the protective cover 4 and is used to dissipate heat from the battery.

[0030] The battery holder 6 is detachably connected to the protective cover 4 and has a slot 61 inside;

[0031] The battery holder 7 is detachably assembled within the battery rack 6 to secure the battery module.

[0032] As a preferred embodiment, based on the above method, further, threaded holes adapted to the bolts 3 are opened at the four corners of the upper surface of the plastic bottom shell 1. One end of the bolt 3 protrudes from the plastic top shell 2 and is threadedly connected to the threaded hole. The threaded connection method facilitates disassembly in the later stage.

[0033] The top of the plastic top shell 2 is also provided with a power connection post 8, and the top of the plastic bottom shell 1 is provided with a through hole for the power connection post 8 to pass through. The top of the power connection post 8 is threaded with a protective cap, which can protect the power connection post 8.

[0034] A rubber strip 9 is also provided between the plastic bottom shell 1 and the plastic top shell 2. The rubber strip 9 is rectangular in shape and can close the connection gap between the plastic bottom shell 1 and the plastic top shell 2.

[0035] As a preferred embodiment, based on the above method, the protective sleeve 4 further has a hollow strip on its side wall, which allows the heat dissipation component to exchange airflow. The heat dissipation component 5 includes a heat dissipation fan 51 disposed inside the protective sleeve 4. When the overall temperature of the battery module rises, the heat dissipation fan 51 is activated to draw the external airflow into the protective sleeve 4, while the heat dissipation fan 51 on the other side draws the airflow out of the protective sleeve 4, thereby completing the airflow convergence to achieve the purpose of heat dissipation.

[0036] The side wall of the battery rack 6 has multiple through slots 62. The through slots 62 are used to reduce the weight of the battery rack 6 and allow airflow. Due to the presence of the through slots 62, airflow is facilitated to achieve better heat dissipation.

[0037] In a preferred embodiment, based on the above method, the battery fixing component 7 further includes a plurality of battery clips 71. The battery clips 71 are hexagonal in shape, with a clip 72 and a limiting groove 73 respectively provided on two adjacent sides. Two battery clips 71 are connected by studs 74.

[0038] The stud 74 has threaded sections at both ends. The top and bottom of the battery clip 71 are provided with threaded mounting holes that are compatible with the stud. When different numbers of battery clips 71 need to be assembled, it is only necessary to thread the stud to two battery clips 71.

[0039] In summary, this crack-resistant battery plastic component uses bolts 3 to connect the plastic bottom shell 1 and the plastic top shell 2, facilitating easy disassembly and replacement of the battery cells. During use, the heat dissipation component 5 blows airflow onto the battery cells, thereby dissipating heat through the convergence of airflows and ensuring the normal operation of the battery module. Specifically, when the overall temperature of the battery module rises, the cooling fan 51 starts to draw external airflow into the protective sleeve 4, while the cooling fan 51 on the other side draws airflow out of the protective sleeve 4, thus achieving the purpose of heat dissipation through airflow convergence. The battery cells are installed in the battery fixing component 7 and then fixed in the battery rack 6 by snap-fit, which facilitates the installation of the battery cells and ensures that there is a gap, which not only effectively fixes the battery cells but also ensures the heat dissipation effect. Different numbers of battery clips 71 can be installed for battery cells of different lengths. Specifically, when it is necessary to install, the clip 72 is inserted into the limiting groove 73 to fix the battery clip 71. When different numbers of battery clips 71 need to be installed, it is only necessary to thread the studs to two battery clips 71.
