Description

Technical Field

[0001] The utility model relates to the technical field of lithium ion batteries, in particular to a packaging structure of a soft-pack lithium ion battery. Background Art

[0002] Soft-pack lithium-ion battery is a special type of lithium-ion battery that uses a polymer shell instead of a traditional metal shell. The structural feature of this type of battery is that it is packed with aluminum-plastic film. If there is a safety hazard, the soft-pack battery will only bulge and crack at most, but will not explode like steel or aluminum shell batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have now become mainstream, and existing lithium batteries need to be packaged using packaging structures when they are used.

[0003] According to a battery packaging structure published on the patent website (authorization announcement number: CN 210837832 U), the battery packaging structure device includes "packaging box, fixing unit, mounting plate, battery body" etc. to package the battery.

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] The packaging structure of the battery utilizes a packaging box, a fixing unit, a mounting plate, a battery body, etc. to package the battery. However, this structure generates heat when the battery is in use. This structure is a sealing mechanism and cannot discharge the generated heat, resulting in an excessively high internal temperature, which affects the service life of the battery. Therefore, this structure needs to be improved. Utility Model Content

[0015] Compared with the prior art, the utility model provides a packaging structure of a soft-pack lithium-ion battery, which has the following beneficial effects:

[0016] 1. The packaging structure of the soft-pack lithium-ion battery can realize the packaging of the battery body in the packaging box through the packaging mechanism, and can fix the battery bodies of different sizes to ensure the stability of the battery body. At the same time, the temperature inside the packaging box is monitored by the temperature sensor, and the opening and closing of the sealing plate are controlled to dissipate heat for the battery body. When the battery body is placed, the reverse threaded rod drives the mounting frame to move forward and backward by turning the knob.

When the temperature sensor senses that the temperature in the packaging box is too high, the electric telescopic rod is started, so that the electric telescopic rod drives the connecting block to move downward. During the downward movement of the connecting block, the concave frame is driven to change its angle through the second rotating rod, so that the concave frame drives the sealing plate fixedly connected to the periphery of the first rotating rod to change its angle in the heat dissipation frame, from a completely closed state to an open state, so that the heat in the packaging box can be discharged and the battery body can be dissipated.

[0017] 2. The packaging structure of the soft-pack lithium-ion battery can support the battery body through the placement mechanism, and can prevent the battery body from directly contacting the packaging box to affect the heat dissipation effect. When the battery body is dissipated, the battery body can be dissipated through the fan to improve the service life of the battery body. First, the battery body is placed on the top of the placement plate. When heat is generated during work, the fan only needs to be started to allow the fan to dissipate heat to the battery body through the ventilation holes. BRIEF DESCRIPTION OF THE DRAWINGS
