Description

Technical Field

[0001] This utility model relates to the field of lithium battery component technology, specifically to a lithium battery component. Background Technology

[0002] A battery is a rechargeable battery that uses lithium as the main active material. It can be repeatedly charged and discharged and has advantages such as high energy density, low self-discharge rate, long life, no memory effect, and compact size. It is widely used in mobile phones, laptops, electric vehicles, portable electronic devices and other fields.

[0003] A lithium battery assembly is an overall battery system composed of multiple lithium battery cells combined in a certain way, used to provide greater voltage and capacity to meet the energy needs of various devices or systems.

[0004] Existing lithium battery components typically include individual cells, battery modules, battery management systems, connectors, and casings. However, traditional lithium battery components often use an aluminum alloy frame and cover to support and fix the battery cells and protect them. The casing structure is relatively simple. When a battery cell spontaneously combusts, it can quickly burn through the casing structure and cause fire damage to other equipment, and in severe cases, personal injury. As a result, the overall protection of lithium battery components is generally poor, posing certain safety hazards. To address these issues, we propose a lithium battery component to solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: Figure 1-8 As shown, this utility model provides a lithium battery assembly, including a housing 1, a cap 2 at the top of the housing 1, and an inner isolation frame 3 inside the housing 1. The inner isolation frame 3 divides the interior of the housing 1 into multiple placement spaces, and battery units are installed in the multiple placement spaces and separated by the inner isolation frame 3. The housing 1, cap 2, and inner isolation frame 3 are hollow structures. The top of the inner isolation frame 3 has multiple connecting top grooves 301. The bottom of the cap 2 is fixedly fitted with a connecting top tube 202 corresponding to the connecting top groove 301. The connecting top tube 202 is movably fitted into the corresponding connecting top groove 301. A sealing top ring 302 is fixedly fitted on the bottom inner side of the connecting top groove 301. The bottom end of the connecting top tube 202 contacts the upper surface of the sealing top ring 302. The connection between the inner isolation frame 3 and the cap 2 is achieved by setting the connecting top tube 202.

[0029] The bottom of the inner frame 3 is fixed with multiple connecting bottom tubes 303. The lower inner wall of the outer shell 1 is provided with a connecting bottom groove 101 corresponding to the connecting bottom tubes 303. The connecting bottom tubes 303 are movably engaged in the corresponding connecting bottom grooves 101. A sealing bottom ring 102 is fixed on the bottom inner side of the connecting bottom groove 101. The bottom end of the connecting bottom tube 303 contacts the upper surface of the sealing bottom ring 102. The connection between the inner frame 3 and the outer shell 1 is achieved by setting the connecting bottom tubes 303.

[0030] A flame retardant storage tank 4 is provided on one side of the outer casing 1. A pump 5 is fixedly installed at the outlet of the flame retardant storage tank 4. An input groove 201 corresponding to the output port of the pump 5 is opened at the bottom of the cover 2. The output port of the pump 5 is fixedly snapped into the input groove 201. When one of the battery cells spontaneously combusts, the separation of the inner frame 3 reduces the spontaneous combustion of other battery cells. The battery cell may burn through the inner side of the outer casing 1, the cover 2, and the inner frame 3. The pump 5 is then turned on, and the flame retardant is introduced into the cover 2 through the input groove 201. It can also be introduced into the inner frame 3 and the outer casing 1 to immediately retard the battery cell position, prevent combustion of other equipment, and reduce personal safety hazards.

[0031] Multiple wire-passing grooves 3001 are provided on the inner frame 3 of the isolation. Each wire-passing groove 3001 is fixedly fitted with a connecting frame 31. By providing multiple wire-passing grooves 3001 and the connecting frame 31 blocking the wire-passing grooves 3001, it is convenient for the electrical wiring between battery units in adjacent placement spaces to pass through and connect through the connecting frame 31.

[0032] A mounting bracket 6 is fixedly installed on the outer wall of the outer casing 1 near the flame retardant storage tank 4. The flame retardant storage tank 4 and the pump 5 are detachably mounted on the mounting bracket 6. A protective cover 7 is fixedly installed on the outer wall of the outer casing 1 near the mounting bracket 6. The flame retardant storage tank 4 and the pump 5 are located in the protective cover 7. The flame retardant storage tank 4 and the pump 5 are protected by the protective cover 7.

[0033] Multiple first seats 11 are fixedly installed on the side of the outer shell 1, and a second seat 21 corresponding to the position of the first seat 11 is fixedly installed on the side of the cover 2. A fixing bolt 12 is threaded between the first seat 11 and the second seat 21 vertically to fix the outer shell 1 and the cover 2.

[0034] Working principle: Battery units are installed in multiple placement spaces and separated by an inner frame 3. Multiple wire grooves 3001 are opened and the connecting frame 31 blocks the wire grooves 3001, so that the electrical wires between battery units in adjacent placement spaces can be connected through the connecting frame 31.

[0035] When one of the battery cells spontaneously combusts, the isolation inner frame 3 reduces the likelihood of other battery cells spontaneously combusting. The battery cell may burn through the outer casing 1, the cover 2, and the inner side of the isolation inner frame 3. The pump 5 is then activated, and flame retardant is introduced into the cover 2 through the input channel 201. It can also be introduced into the isolation inner frame 3 and the outer casing 1 to immediately retard the battery cell location, preventing combustion of other equipment and reducing personal safety hazards.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
