[0029] In air-cooled soft-pack modules, the insulation of the soft-pack battery tabs will fail due to the high water vapor content in the air, so the soft-pack battery tabs need to be insulated and protected. The current measure is to use potting glue to pot the tab area. The side panel structure is needed to limit the direction of glue flow. At present, the side panel structure has glue overflow after glue pouring, and the glue pouring situation cannot be observed.

[0030] The present application proposes a battery, which can better observe the glue filling situation, thereby better reducing the risk of glue overflow after glue filling.

[0031] Reference below Figure 1-Figure 4 A battery according to an embodiment of the present invention is described.

[0032] like Figure 1-Figure 4 As shown, the battery according to the embodiment of the utility model includes a battery assembly 10, a side plate 2, an insulating member and a sealing member, the battery assembly 10 includes a frame unit 1, the frame unit 1 includes a battery cell 11 and a single body frame 12, the battery cell 11 is installed in the single body frame 12, and a pole ear 111 is provided at the first end of the battery cell 11, the side plate 2 is installed at the first end of the single body frame 12, and an insulating space is defined between the side plate 2 and the single body frame 12, at least part of the pole ear 111 is located in the insulating space, the insulating member is arranged in the insulating space, at least part of the pole ear 111 is embedded in the insulating member, the sealing member is installed on the outer periphery of the side plate 2, and is used to seal the assembly gap between the side plate 2 and the single body frame 12, and at least one of the sealing member and the side plate 2 is a light-transmitting member.

[0033] That is to say, after the battery cell 11 is installed in the single body frame 12, in order to insulate the pole ear 111 at the end of the battery cell 11, the side plate 2 can be installed at the first end of the single body frame 12. Here, the first end is only for the convenience of describing the position of the pole ear 111 and the installation position of the side plate 2, and is not a limitation of the present application. When the side plate 2 is installed at the first end of the single body frame 12, an insulating space can be defined between the side plate 2 and the single body frame 12, and there is an assembly gap between the side plate 2 and the single body frame 12. Therefore, the assembly gap can be sealed by a seal. Sealing, whereby the sealing member can complete the sealing of the insulating space. Exemplarily, the sealing member is a light-transmitting member, and therefore, the situation inside the insulating space can be easily seen from the outside through the sealing member. Exemplarily, the insulating member is insulating glue, and the insulating glue can be injected into the insulating space, and then after the insulating glue solidifies, part of the pole ear 111 can be embedded in the insulating member formed by the insulating glue. Through the light-transmitting sealing member, the situation inside the insulating space can be easily seen from the outside, which can better avoid the problem of glue overflow during glue pouring.

[0034] Exemplarily, the side panel 2 is a light-transmitting member, and therefore, the situation inside the insulating space can be easily seen from the outside through the side panel 2, which can better avoid the problem of glue overflow during glue pouring.

[0035] Therefore, according to the battery of the embodiment of the utility model, by making at least one of the seal and the side plate 2 a light-transmitting member, the situation inside the insulating space can be better seen from the outside, and the problem of glue overflow during glue filling can be better avoided.

[0036] In some embodiments of the present invention, Figure 1-Figure 4 As shown, a plurality of frame units 1 are provided, and the plurality of frame units 1 are stacked along a first direction, and an insulating space is constructed between the side plate 2 and the single frame 12 of the plurality of frame units 1. That is, the plurality of single frames 12 can be stacked along the first direction to construct a module frame. Figure 1 As shown, the first direction can refer to the left and right direction, and the first end of the above-mentioned battery cell 11 and the first end of the single body frame 12 can be the front. Therefore, a side panel 2 is arranged in front of the module frame, and an insulating space is constructed between the side panel 2 and the module frame. There are multiple pole ears 111 in the insulating space. In this way, when glue is poured into the insulating space, multiple pole ears 111 can be insulated at the same time, which can improve the insulation efficiency.

[0037] In some embodiments of the present invention, the side panel 2 includes a side panel body 21 and a connecting support plate 22, one end of the connecting support plate 22 is connected to one side of the second direction of the side panel body 21, and the other end of the connecting support plate 22 is detachably connected to the side of the single frame 12 in the second direction.

[0038] like Figure 1-Figure 4 As shown, the side panel body 21 extends in the left-right direction, the front end of the connecting support plate 22 is connected to the upper end of the side panel body 21, and the rear end of the connecting support plate 22 is fixed to the upper side surface of the single body frame 12. Thus, the side panel 2 can be better mounted on the single body frame 12 through the connecting support plate 22.

[0039] Alternatively, if Figure 1-Figure 4 As shown, a first latching protrusion 221 is provided on the connecting support plate 22, and a first latching hole 121 cooperating with the first latching protrusion 221 is provided on the single body frame 12. Thus, through the cooperation between the first latching protrusion 221 and the first latching hole 121, the assembly between the side panel 2 and the single body frame 12 is relatively simple, the assembly efficiency is high, and it is easy to disassemble, which can improve the disassembly efficiency between the side panel 2 and the single body frame 12.

[0040] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the first convex part 221 is provided with a glue injection hole 222 that penetrates the connecting support plate 22 along the second direction, and the glue injection hole 222 is connected to the insulating space. That is to say, after the insulating glue is poured and solidified in the insulating space, the insulating glue changes from liquid to solid, and the volume is reduced, which easily causes part of the pole ear 111 to leak out. In this application, by setting the glue injection hole 222, the glue in the insulating space can be well filled, and because the sealing member is a light-transmitting member, the glue filling state in the insulating space can be well observed, which can well reduce the risk of glue overflow during glue filling. Among them, the second direction can refer to Figure 2 The up and down directions shown in the figure will not be repeated in the following description of this application.

[0041] Furthermore, if Figure 1-Figure 4 As shown, by providing the glue injection hole 222 at the position of the first locking protrusion 221, it is beneficial to stabilize the glue injection hole 222 and avoid affecting glue filling after the glue injection hole 222 is deformed.

[0042] Alternatively, if Figure 1-Figure 4 As shown, the single body frame 12 is provided with a glue injection channel 122, which is connected between the first clamping hole 121 and the insulating space. That is, when the first clamping protrusion 221 is matched with the first clamping hole 121, the glue injection hole 222 on the first clamping protrusion 221 can be connected with the insulating space through the first clamping hole 121, which has a simple structure and is convenient for glue filling.

[0043] In some embodiments of the present invention, Figure 1-Figure 4 As shown, a plurality of connecting support plates 22 are provided, and the plurality of connecting support plates 22 are spaced apart and arranged along a first direction, and the first direction and the second direction are perpendicular to each other.

[0044] For example, Figure 1-Figure 4 As shown, multiple connecting support plates 22 can be fixedly connected to a single frame 12 at the same time; exemplarily, multiple single frames 12 are provided, and multiple connecting support plates 22 can be fixedly connected to multiple single frames 12 one by one; exemplarily, multiple single frames 12 are provided, and the number of connecting support plates 22 is less than the number of single frames 12, so that multiple connecting support plates 22 can be arranged spaced apart in the left and right directions according to actual conditions. In the above example, by providing multiple connecting support plates 22, the connection reliability of the side panel 2 can be improved.

[0045] In some embodiments of the present invention, Figure 1-Figure 4 As shown, a second locking protrusion 23 is provided on the side of the side plate 2 facing the single body frame 12 , and a second locking hole 123 matching with the second locking protrusion 23 is provided on the single body frame 12 .

[0046] like Figure 1-Figure 4 As shown, a second clamping hole 123 is provided on the front side of the single body frame 12, and a second clamping protrusion 23 which is clamped and matched with the second clamping hole 123 is provided on the side panel 2. Thus, the upper end of the side panel 2 is fixedly connected to the single body frame 12 through the cooperation of the first clamping hole 121 and the first clamping protrusion 221, and the lower end of the side panel 2 is fixedly connected to the single body frame 12 through the cooperation of the second clamping hole 123 and the second clamping protrusion 23, and the connection effect is good.

[0047] In some embodiments of the present invention, the insulating member includes insulating glue, which can not only better insulate the tabs 111 , but also improve the connection strength between the single body frame 12 and the side plate 2 .

[0048] Exemplarily, the insulating member may also be other insulating materials, which are poured into the insulating space when the insulating material is liquid, and then the pole ear 111 is insulated when the insulating material solidifies. The present application does not limit the insulating material.

[0049] In some embodiments of the present invention, the sealing member is a rubber-blocking foam, which can better seal the assembly gap between the side plate 2 and the single frame 12, and can also better block the insulating glue. Here, the rubber-blocking foam can be made of a light-transmitting material, so that the glue filling state in the insulating space can be better observed through the rubber-blocking foam.

[0050] Exemplarily, the side panel 2 may also be a light-transmitting member, which is not limited in the present application.
