Description

Technical Field

[0001] This utility model belongs to the field of battery module technology, and in particular relates to an insulating protection component for electrical connection of battery modules. Background Technology

[0002] A battery module is a battery assembly consisting of two or more individual batteries connected in series, parallel, or series-parallel configurations. The end plate is one of the core components of a battery module, typically manufactured from injection-molded parts or die-cast aluminum profiles. The end plate has a base to provide mounting points for the battery module's output terminals. Inadequate protection at the output terminals can easily lead to short circuits in the battery module, causing safety hazards.

[0003] To improve the safety of battery modules, protective covers are typically installed on the base. Except for the mounting points on the base used to connect the output terminals, the rest of the base and the protective cover are made of insulating material, thus providing insulation protection for the output terminals. However, the protective covers are mostly fixed to the base with screws or other fasteners, which is inconvenient to install. Furthermore, these fasteners are usually made of conductive materials; if one end of the fastener is exposed, it can easily lead to short circuits in the product or personal injury due to contact.

[0004] Existing insulating protection components for battery module electrical connections are insufficient to meet safety performance requirements. For example, an insulating protection component for battery module electrical connections, as shown in patent publication number CN218351688U, includes a base and a protective cover. Although the aforementioned patent can adjust the position of the base according to the position of the battery module output terminal, the open installation space on one side affects the safety performance of the insulating protection component.

[0005] To address this issue, we propose an insulating protection component for the electrical connection of battery modules. Utility Model Content

A spring component for driving the flip cover to rotate toward the opening is provided between the flip cover and the top cover.

[0009] The electric connecting piece is electrically connected with the pole column through the inner wall of the end portion, and the outer wall of the end portion is attached to the inner wall of the through hole.

[0010] Preferably, protrusions are fixedly connected to the two sides of the bottom surface of the top cover, and a groove is formed in the top of the base to fit the protrusions.

[0011] Preferably, mounting blocks are fixedly connected to the four corners of the bottom surface of the top cover, and two flaps are respectively hingedly arranged between the two mounting blocks on the two sides, and the elastic assembly comprises torsion springs arranged between the flaps and the top cover.

[0012] Preferably, the number of torsion springs on the flaps is two, and the torsion springs are symmetrically arranged on the two sides of the flaps.

[0013] Preferably, the side surface of the mounting block is attached to the inner wall of the base, the side surface of the flap is attached to the inner wall of the base, and the top end of the flap is attached to the top surface of the top cover.

[0014] Preferably, a limiting block is fixedly connected to the lower part of the mounting block to cooperate with the flap.

[0015] Preferably, when the flap is attached to the limiting block, the bottom end of the flap is attached to the inner bottom wall of the base.

[0016] In summary, the technical effects and advantages of the present application are as follows: the battery module electric connection insulation protection assembly is convenient for wiring of the electric connecting piece through the openings on the two sides, realizes insulation protection of the openings through cooperation of the top cover, the base and the flap, and realizes self-adaptive closure of the openings through the elastic assembly to adapt to the thickness of the electric connecting piece. Compared with the prior art, the installation space on one side is not open, and the safety performance of the insulation protection assembly is not affected, thereby improving the practicability and safety of the device.

The base 2 is provided with a through hole 4 in the middle for placing the pole 3 of the battery 1, and both sides of the base 2 are provided with an opening 5, and the top of the base 2 is detachably connected with a top cover 6, both sides of the bottom surface of the top cover 6 are hingedly provided with a flip cover 7, and the bottom end of the flip cover 7 is directed to one side of the through hole 4, and a spring assembly is arranged between the flip cover 7 and the top cover 6 to drive the flip cover 7 to rotate towards the opening 5.

[0024] Further comprising an electric connecting piece 8, the inner side wall of the end of the electric connecting piece 8 is electrically connected with the pole 3 of the battery 1, and the outer side wall of the end of the electric connecting piece 8 is attached to the inner side wall of the through hole 4. The middle part of the electric connecting piece 8 is prior art, including wires and protective layers, which are common and will not be described in detail.

[0025] With reference to Figures 1-3 The insulating protection assembly for battery module electric connection is used by aligning the through hole 4 with the pole 3 of the battery 1, then fixing and installing the base 2 on the battery 1, and then detachably fixing and connecting the top cover 6 on the base 2 after the installation of the base 2 is completed.

[0026] When the electric connection of the battery module is needed, the top cover 6 is detached, and then the end of the electric connecting piece 8 is inserted into the through hole 4, at this time the pole 3 of the battery 1 is electrically connected with the inner side wall of the end of the electric connecting piece 8. After completion, the top cover 6 is detachably fixed and connected on the base 2, one side of the flip cover 7 is attached to the inner bottom wall of the base 2 under the action of the spring assembly, realizing insulation protection, and the other side of the flip cover 7 is attached to the electric connecting piece 8 under the action of the spring assembly, realizing insulation protection and auxiliary fixing of the electric connecting piece 8.

[0027] The bottom surface of the top cover 6 is fixedly connected with a protruding block 9, and the top of the base 2 is provided with a recess 10 for interference fit of the protruding block 9. The protruding block 9 and the recess 10 are interference fit, and detachable fixed connection is realized by deformation of itself.

[0028] The bottom surface of the top cover 6 is fixedly connected with a mounting block 11, and two flip covers 7 are hingedly arranged between two mounting blocks 11 on both sides, and the spring assembly comprises a torsion spring 12 arranged between the flip cover 7 and the top cover 6, and the flip cover 7 is automatically rotated towards the opening 5 through the torsion spring 12.
