Description

[0001] The utility model relates to the technical field of batteries, in particular to a mounting assembly and a lithium-ion battery. Background Art

[0002] Currently, lithium-ion battery energy storage systems are all pursuing lower costs and higher energy densities. According to relevant standard specifications, energy storage battery packs need to undergo short-circuit tests. To meet the specifications, fuses are configured inside the lithium-ion batteries for testing.

[0003] Currently, to meet the installation requirements during corresponding tests, fuses are usually arranged in a mounting seat formed by snap-fitting a plastic upper housing and a plastic lower housing. The production of such a mounting seat requires mold opening. To meet the structural strength of the mold itself and the snap-fitting requirements around the plastic upper housing and the plastic lower housing, the self-wall thickness of the manufactured mounting seat is relatively large. Therefore, the setting of the mounting seat occupies a relatively large accommodation space inside the lithium-ion battery, thereby reducing the volume energy density of the lithium-ion battery. At the same time, the mold opening for manufacturing the mounting seat greatly increases the manufacturing cost of the lithium-ion battery. Summary of the Utility Model

Detailed Embodiments

[0028] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, with reference to the accompanying drawings, the preferred embodiments of the present utility model will be described in detail.

[0029] An embodiment of the present utility model provides an installation component, as Figures 1 to 3 shown, including an insulating mounting member 10, a first insulating seat 210, a second insulating seat 220, a first conductive member 310 and a second conductive member 320. The insulating mounting member 10 includes a connected first insulating baffle 110 and a second insulating baffle 120, and an open insulating space 101 is formed between the first insulating baffle 110 and the second insulating baffle 120; the first insulating seat 210 and the second insulating seat 220 are disposed on the insulating mounting member 10 and located inside the insulating space 101; the first conductive member 310 is disposed on the first insulating seat 210, the second conductive member 320 is disposed on the second insulating seat 220, and the first conductive member 310 and the second conductive member 320 extend outwards from the insulating space 101.

[0030] In the fuse mounting assembly provided by the embodiment of the present utility model, the insulating mounting member 10 provides an insulating mounting environment for the fuse 40. Specifically, an open insulating space 101 is formed between the first insulating baffle 110 and the second insulating baffle 120 of the insulating mounting member 10. A first insulating seat 210 and a second insulating seat 220 are arranged in the insulating space 101. In the actual application process, one end of the fuse 40 is arranged on the first insulating seat 210 and electrically connected to the first conductive member 310 arranged on the first insulating seat 210, and the other end of the fuse 40 is arranged on the second insulating seat 220 and electrically connected to the second conductive member 320 arranged on the second insulating seat 220, so that the fuse 40 is fixedly arranged in the insulating space 101 formed by the first insulating seat 210 and the second insulating seat 220. The fuse 40 is insulated from the panel 570 and the end plate 580 inside the lithium-ion battery housing 50 through the first insulating baffle 110 and the second insulating baffle 120, and the first conductive member 310 and the second conductive member 320 extend out from the open insulating space 101 to connect the fuse 40 into the detection circuit of the lithium-ion battery, meeting the installation requirements for corresponding tests. The above-mentioned insulating mounting member 10 has a simple structure, does not require mold opening for manufacturing, can reduce the thickness of the first insulating baffle 110 and the second insulating baffle 120 themselves, and further reduces the thickness of the insulating mounting member 10 in the Y direction, so that the insulating mounting member 10 of this embodiment is smaller than the volume of the existing mounting seat formed by clamping a plastic upper housing and a plastic lower housing. Therefore, the occupied space of the mounting assembly in the lithium-ion battery is reduced, and further the volume energy density of the lithium-ion battery is improved, and the mounting assembly saves the mold opening cost and reduces the manufacturing cost of the lithium-ion battery.

[0031] In this embodiment, the thickness of the first insulating baffle 110 and the second insulating baffle 120 during application is generally within 1 mm, and the thickness of the corresponding molds of the plastic upper housing and the plastic lower housing after mold opening is generally above 3 mm. Therefore, the mounting assembly of this embodiment reduces its occupied space inside the housing 50 in the Y direction.

[0032] As a preferred solution of this embodiment, refer to Figure 1 , the insulating mounting member 10 further includes an insulating bottom plate 130. The insulating bottom plate 130 is respectively connected to the first insulating baffle 110 and the second insulating baffle 120, and the first insulating seat 210 and the second insulating seat 220 are arranged on the insulating bottom plate 130.

[0033] Among them, a specific structural form of the insulating mounting member is given in this embodiment. By arranging the insulating bottom plate 130 to connect the first insulating baffle 110 and the second insulating baffle 120, and the insulating bottom plate 130 provides a stable installation condition for the first insulating seat 210 and the second insulating seat 220, and further provides a stable installation environment for the setting of the fuse 40 in the lithium-ion battery.

[0034] As a preferred solution of this embodiment, the insulating mounting member 10 has a U-shaped structure. The first conductive member 310 extends outward along the top of the U-shaped structure. After the second conductive member 320 extends out of the top of the U-shaped structure, it extends out along any one side of the U-shaped structure.

[0035] Referring to Figure 1 , the set structure of this embodiment can, while satisfying the test installation and adjustment of the fuse 40, also increase the electrical clearance and creepage distance between the first conductor and the second conductor and the surrounding conductors, thereby playing a role in strengthening insulation.

[0036] Among them, the set heights of the first insulating baffle 110 and the second insulating baffle 120 are suitable for the layout environment of the internal module of the lithium-ion battery. Referring to Figure 1 , in the internal environment of the lithium-ion battery in this example, a specific set structure of the first insulating baffle 110 and the second insulating baffle 120 is given. Among them, the height of the first insulating baffle 110 is less than the height of the second insulating baffle 120. The heights of the first insulating baffle 110 and the second insulating baffle 120 are adapted to the set positions and sizes of the inner panel 570 and the end plate 580 of the housing 50, and only need to achieve isolation of the fuse 40 to meet the test requirements, and no specific limitation is made here.

[0037] An open insulating space 101 is formed between the first insulating baffle 110 and the second insulating baffle 120 of this embodiment. Referring to Figure 1 , the top of the insulating mounting member 10 having a U-shaped structure is an open structure. Therefore, compared with the existing structure in which the upper plastic housing and the plastic lower housing are clamped, the structure is simple, the thickness of the insulating mounting member 10 itself in the Z direction is smaller, and the space occupied by the thickness of the top of the existing plastic upper housing itself is saved. Therefore, the overall height of the insulating mounting member 10 in the Z direction is reduced; continuing to refer to Figure 1 , along the X direction, both sides of the insulating mounting member 10 having a U-shaped structure are open structures. Therefore, compared with the existing structure in which the upper plastic housing and the plastic lower housing are clamped, the structure is simple, and the space occupied by the wall thickness at both ends of the existing mounting seat along the X direction is saved; in summary, the volume of the mounting assembly is smaller than that of the existing mounting seat formed by clamping the plastic upper housing and the plastic lower housing. Therefore, the space occupied by the mounting assembly in the lithium-ion battery is reduced again, thereby improving the volume energy density of the lithium-ion battery. At the same time, the production of the insulating mounting member 10 does not require mold opening, and the formation of the first insulating baffle 110, the insulating bottom plate 130, and the second insulating baffle 120 can be achieved by bending with tools, or even by manual bending by workers. Therefore, compared with mold manufacturing, the production cost is greatly reduced and the production efficiency is improved.

[0038] Referring to Figure 1, To improve the setting stability of the first conductive member 310 and the second conductive member 320 on the insulating mounting member 10, a part of the first conductive member 310 located within the insulating space 101 abuts against the first insulating baffle 110, enhancing the setting stability of the first conductive member 310 on the insulating mounting member 10. A part of the second conductive member 320 located within the insulating space 101 abuts against the second insulating baffle 120, enhancing the setting stability of the second conductive member 320 on the insulating mounting member 10.

[0039] As a preferred solution of this embodiment, a bending structure 311 is formed on the free end of the first conductive member 310, and the convex surface of the bending structure 311 faces the second conductive member 320.

[0040] During the actual production process, to ensure the applicability of the first conductive member 310 in different lithium-ion batteries, the production length of the first conductive member 310 needs to be relatively long. When applied to a lithium-ion battery with a relatively small space in the housing 50, the free end of the first conductive member 310 can be bent according to the actual situation to form the bending structure 311, thereby improving the usability of the first conductive member 310. Setting the convex surface of the bending structure 311 to face the second conductive member 320 can prevent the first conductive member 310 from contacting the panel 570 and ensure the detection requirements of the fuse 40. Refer to Figure 1 , the bending structure 311 is located above the fuse 40.

[0041] As a preferred solution of this embodiment, an avoidance notch 1101 is formed on the first insulating baffle 110 and / or the second insulating baffle 120.

[0042] Due to the large number of structural components inside the lithium-ion battery, by forming the avoidance notch 1101 on the first insulating baffle 110 and / or the second insulating baffle 120 during the setting of the insulating mounting member 10, it is convenient for the insulating mounting member 10 to cooperate with the internal environment of the lithium-ion battery, preventing interference to the installation of the installation assembly caused by the above-mentioned structural components, so as to facilitate the installation of the installation assembly of this embodiment on the lithium-ion battery.

[0043] In summary, the setting position of the above-mentioned avoidance notch 1101 is adapted to the internal structure of the lithium-ion battery, and its specific position and size are not limited. Refer to Figure 2 , an example of forming the avoidance notch 1101 on the first insulating baffle 110 is given.

[0044] As a preferred solution of this embodiment, refer to Figure 3 and Figure 9, a first insulating seat 210 is provided with a first mounting rod 211, a second insulating seat 220 is provided with a second mounting rod 221, a first fastener 212 is provided on the first mounting rod 211, a second fastener 222 is provided on the second mounting rod 221, a first conductive member 310 is sleeved on the first mounting rod 211 and is located between the first insulating seat 210 and the first fastener 212, and a second conductive member 320 is sleeved on the second mounting rod 221 and is located between the second insulating seat 220 and the second fastener 222.

[0045] In order to strengthen the connection strength of the fuse 40 on the first insulating seat 210 and the second insulating seat 220 and the electrical connection relationship between the two ends of the fuse 40 and the first conductive member 310 and the second conductive member 320 respectively, in this embodiment, an installation form of the fuse 40 is given. Specifically, a first mounting rod 211 is provided on the first insulating seat 210, and a second mounting rod 221 is provided on the second insulating seat 220. During the actual installation process, the two ends of the fuse 40 are respectively sleeved on the first mounting rod 211 and the second mounting rod 221, and then the first conductive member 310 is sleeved on the first mounting rod 211, and the second conductive member 320 is sleeved on the second mounting rod 221 so that both the first conductive member 310 and the second conductive member 320 are electrically connected to the fuse 40. Finally, the first fastener 212 is sleeved on the first mounting rod 211, and the second fastener 222 is sleeved on the second mounting rod 221 to strengthen the setting stability of the fuse 40 on the installation component by adjusting the first fastener 212 and the second fastener 222.

[0046] The above-mentioned first mounting rod 211 and second mounting rod 221 adopt screws, and the first fastener 212 and second fastener 222 adopt nuts. The bolt connection is realized through the cooperation of the screw and the nut, which can ensure the installation stability of the fuse 40 and improve the operation convenience of the fuse 40 set on the installation component at the same time; at the same time, the above-mentioned first mounting rod 211 and second mounting rod 221 and the first fastener 212 and second fastener 222 are made of insulating materials.

[0047] As a preferred solution of this embodiment, the insulating mounting member 10 is an integrally formed structure.

[0048] Among them, the above-mentioned insulating mounting member 10 is an integrally formed structure, which is simple and easy to obtain in the production process, reduces costs, simplifies the installation steps, and improves the assembly efficiency in the lithium-ion battery.
