Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery packaging, and more specifically, to a lithium battery packaging component. Background Art

[0002] A lithium battery packaging component is a component for protecting the exterior of a lithium battery component. During the lithium battery packaging process, the quality and performance of these components directly affect the safety, stability, and service life of the battery. High-quality packaging components can effectively improve the energy density, cycle life, and safety performance of the battery.

[0006] For this reason, the specific technical solution adopted by the utility model is as follows:

[0007] A lithium battery packaging component includes an outer protective installation soft frame that plays a protective role. An inner protective installation frame is provided inside the outer protective installation soft frame, and a heat conduction and heat dissipation plate for cooling is fixedly connected between the inner protective installation frame and the outer protective installation soft frame. Rubber air bags are symmetrically embedded on both sides of the outer protective installation soft frame. Heat dissipation ventilation holes are symmetrically opened inside the outer protective installation soft frame, and the heat dissipation ventilation holes are located on both sides of the rubber air bags.

[0008] Preferably, a second installation embedding groove is opened inside the outer protective installation soft frame, and the rubber air bag is located inside the second installation embedding groove.

[0012] Preferably, an outer protective wall is fixedly connected to the outside of the rubber airbag.

[0013] Preferably, a heat-conducting film is fixedly connected to the inner side of the inner protective mounting frame.

[0014] The present utility model has the following beneficial effects:

[0015] Compared with the prior art, with the mutual cooperation of the rubber airbag and the heat dissipation ventilation holes, when the internal temperature of the entire battery assembly is relatively high, the rubber airbag expands due to heat, separating the two sides of the outer protective mounting soft frame from the temperature-conducting heat dissipation plate, so that a flow channel for the internal high-temperature gas to circulate is formed between the outer protective mounting soft frame and the temperature-conducting heat dissipation plate, assisting in the heat dissipation of the internal high-temperature gas and reducing the impact of the high temperature inside the battery assembly on the battery assembly.

[0027] Embodiment 1

[0028] As Figures 1-5 shown, a lithium battery packaging component according to an embodiment of the present utility model includes an outer protective installation soft frame 1 that plays a protective role. An inner protective installation frame 2 is provided inside the outer protective installation soft frame 1, and a temperature conduction heat dissipation plate 3 for cooling is fixedly connected between the inner protective installation frame 2 and the outer protective installation soft frame 1. Rubber airbags 4 are symmetrically embedded on both sides of the outer protective installation soft frame 1. Heat dissipation ventilation holes 12 are symmetrically opened inside the outer protective installation soft frame 1, and the heat dissipation ventilation holes 12 are located on both sides of the rubber airbags 4;

[0029] In this embodiment, the outer protective mounting soft frame 1 is an external protective mounting part of the entire encapsulation component, which plays a role in protecting the entire lithium battery component. The inner protective mounting frame 2 located in the outer protective mounting soft frame 1 is an inner protection component in the entire encapsulation component. On the one hand, it plays a buffering role for the internal battery component, and on the other hand, it is used to protect the battery. The temperature conduction and heat dissipation plate 3 plays a role in temperature conduction and is used to assist the battery component in heat dissipation, improving the efficiency of battery heat dissipation. The rubber airbag 4 located in the outer protective mounting soft frame 1 is used when the internal temperature of the entire battery component is relatively high. When the rubber airbag 4 expands due to heat, it separates the two sides of the outer protective mounting soft frame 1 from the temperature conduction and heat dissipation plate 3, so that a flow channel for the internal high-temperature gas to circulate is formed between the outer protective mounting soft frame 1 and the temperature conduction and heat dissipation plate 3, assisting in the heat dissipation of the internal high-temperature gas. The heat dissipation ventilation holes 12 on the outer protective mounting soft frame 1 are used to provide a space for gas exchange with the external space environment.

[0030] Embodiment 2

[0031] As Figure 1 and Figure 5 shown, in addition to the above-mentioned Embodiment 1 of the lithium battery encapsulation component of the present utility model, it also has the following technical features: A second installation embedding groove 13 is opened inside the outer protective mounting soft frame 1, and the rubber airbag 4 is located inside the second installation embedding groove 13. A first installation embedding groove 11 is formed between the outer protective mounting soft frame 1 and the inner protective mounting frame 2, and the temperature conduction and heat dissipation plate 3 is located inside the first installation embedding groove 11. A sealing mounting frame 5 is provided outside the inner protective mounting frame 2 and the temperature conduction and heat dissipation plate 3, and the sealing mounting frame 5 is fixedly connected to the top edge of the outer protective mounting soft frame 1. A plurality of connecting plates 51 are fixedly connected to the top of the sealing mounting frame 5. An outer protective wall 41 is fixedly connected to the outside of the rubber airbag 4. A heat conduction film 21 is fixedly connected to the inner side of the inner protective mounting frame 2.

[0032] Among them, the second installation embedding groove 13 is used to provide an installation space for the rubber airbag 4, the first installation embedding groove 11 is used to provide an installation space for the temperature conduction and heat dissipation plate 3, the sealing mounting frame 5 is used to install and seal one side of the temperature conduction and heat dissipation plate 3 and the inner protective mounting frame 2, forming a protective part outside the inner protective mounting frame 2 and the temperature conduction and heat dissipation plate 3. The connecting plate 51 plays a connecting role and is also used to improve the connection stability of the sealing mounting frame 5. The outer protective wall 41 plays a role in strengthening and protecting the outside of the rubber airbag 4, and the heat conduction film 21 plays a role in further protecting the inner battery component.

[0033] In summary, by means of the above technical solution of the present utility model, when the device is in use and the inner battery assembly gets hot during use, the high temperature inside is quickly diffused to the outside through the heat conduction and dissipation plate 3. At the same time, when the rubber airbag 4 is affected by the hot gas, the rubber airbag 4 expands after being heated. And when the rubber airbag 4 expands, it can separate the two sides of the outer protective installation soft frame 1 from the heat conduction and dissipation plate 3, so that a flow channel for the internal hot gas to circulate is formed between the outer protective installation soft frame 1 and the heat conduction and dissipation plate 3, assisting in the heat dissipation of the internal hot gas. At this time, the internal hot gas can be discharged to the outside through the heat dissipation ventilation holes 12.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
