The present application provides a battery device, as shown in fig. 1 and 2, which includes a cover plate 2 and a harness spacer 1, and a clip 3 for connecting the cover plate 2 and the harness spacer 1; the wiring harness isolation plate 1 is provided with a drainage groove 11 at the connecting position of the clamp 3, and the drainage groove 11 is communicated with the outside of the wiring harness isolation plate 1.

The application provides a battery device, staple 3 hookup location to apron 2 and pencil division board 1 has designed, it is concrete, staple 3 hookup location department at pencil division board 1 has set up water drainage tank 11, this water drainage tank 11 intercommunication pencil division board 1's outside, can realize assembling and directional discharge to liquid, permeate to pencil division board 1 back from staple 3 hookup of apron 2 as liquid, can flow in pencil division board 1's water drainage tank 11, and discharge to pencil division board 1 outside through water drainage tank 11, thereby, can avoid liquid to cause the corruption to the metal busbar on pencil division board 1 or the monomer battery of pencil division board 1 below. Furthermore, the corrosion condition of metal parts in the battery device can be improved, the service life of the parts of the battery device is prolonged, the insulating property of the battery device is improved, and the safety and the reliability of the battery device are ensured.

For example, after the battery device is subjected to a salt spray test, the condensed water flows from the staple 3 connecting gap to the drainage groove 11 of the harness partition board 1 and is drained to the outside of the harness partition board 1 through the drainage groove 11, and further, corrosion of metal parts (a battery cover plate, a battery shell, a metal bus bar and the like) caused by the condensed water containing NaCl can be greatly improved.

In some embodiments, the battery device may include a battery module or a battery pack. Specifically, the cover plate 2 and the wire harness isolation plate 1 can be arranged in the battery module; or, the battery pack adopts a design without a battery module, and the cover plate 2 and the wire harness isolation plate 1 are directly positioned in the box body of the battery pack.

In some embodiments, as shown in fig. 1 and 2, the harness insulation board 1 is further provided with a drainage channel 12, the drainage channel 12 extends to the outside of the harness insulation board 1, and the drainage groove 11 is communicated with the drainage channel 12.

For example, after the liquid flows from the staple 3 connecting gap of the cover plate 2 to the harness isolation plate 1, the liquid enters the drainage channel 11 of the harness isolation plate 1 and flows to the outside of the harness isolation plate 1 along the drainage flow channel 12 connected with the drainage channel 11, and further, corrosion to metal parts such as a battery cover plate and a metal bus bar is avoided.

Illustratively, one end of the drainage channel 12 is communicated with the drainage channel 11, and the other end extends to the edge of the wiring harness isolation plate 1 and is close to the peripheral side face of the battery device, so that after liquid is drained out of the wiring harness isolation plate 1 through the drainage channel 12, drainage can be continued until the liquid is drained out of the battery device. In addition, the drainage flow channel 12 can also extend out of the edge of the wire harness isolation plate 1 and exceed the edge of the upper surface of the battery pack below the wire harness isolation plate 1, so that liquid is prevented from dripping onto the battery pack after flowing out of the wire harness isolation plate 1 along the drainage flow channel 12.

In some embodiments, as shown in fig. 1 and 2, the drain groove 11 is located on a side of the wire harness isolation plate 1 facing the cover plate 2. Accordingly, the drainage channel 12 is also located on the side of the strand insulation 1 facing the cover plate 2.

Thus, after liquid enters from the staple 3 connecting gap of the cover plate 2, the liquid can directly flow into the drainage groove 11 of the wire harness isolation plate 1 and be drained in time, and the liquid is prevented from contacting metal parts below the wire harness isolation plate 1.

In some embodiments, as shown in fig. 1, 2 and 3, the harness insulation panel 1 is provided with a first connection hole 10 to which the clamp 3 is connected. Accordingly, the cover plate 2 is provided with second coupling holes 20 to which the staples 3 are coupled. Specifically, as shown in fig. 4, the staple 3 includes an insertion shaft 32 and an upper cover 31 located at one end of the insertion shaft 32, the insertion shaft 32 passes through the first connection hole 10 and the second connection hole 20 to connect the wire harness isolation plate 1 and the cover plate 2, and the upper cover 31 is located at one side of the cover plate 2 facing away from the wire harness isolation plate 1.

Illustratively, as shown in fig. 2, a drain groove 11 is provided around the first connection hole 10. For example, the drain groove 11 may be an annular groove surrounding the first connection hole 10.

Illustratively, as shown in fig. 1, 2 and 3, the outer diameter of the water discharge groove 11 is larger than the diameter of the second connection hole 20, and the inner diameter of the water discharge groove 11 is smaller than the diameter of the second connection hole 20. Like this, the projection of the border of second connecting hole 20 on pencil division board 1 place plane is located water drainage tank 11, when liquid from second connecting hole 20 border infiltration battery device of apron 2, will directly fall into water drainage tank 11, and then, liquid can be discharged in time with high efficiency, avoids liquid to contact the metalwork of pencil division board 1 below.

Illustratively, as shown in fig. 1 and 3, the cover plate 2 is provided with a sunken portion 21 recessed toward one side of the wire harness isolation plate 1, and the second connection hole 20 is provided in the sunken portion 21, that is, the second connection hole 20 is a sunken opening. Thus, the upper cover 31 of the staple 3 is accommodated in the sinking portion 21 of the cover plate 2, which can save space and avoid interference with other structures.

Further, as shown in fig. 1, 2 and 3, the harness isolation plate 1 may be provided with an accommodating groove 13 at a position corresponding to the sunken part 21 of the cover plate 2, and the accommodating groove 13 may accommodate the sunken part 21 of the cover plate 2; in addition, the radial dimension of this holding tank 13 is greater than the aperture of the second connecting hole 20 of apron 2, and water drainage tank 11 sets up in this holding tank 13, and then, this holding tank 13 can play the effect of catchmenting to the liquid from the infiltration of second connecting hole 20 for liquid can assemble to water drainage tank 11 in, and can avoid liquid overflow water drainage tank 11 back flood to other positions of pencil division board 1.

In some embodiments, as shown in fig. 1 and 2, the harness isolation plate 1 is provided with a boss 14 protruding toward one side of the cover plate 2; the first connection hole 10 of the wire harness isolation plate 1 penetrates through the boss 14, in other words, the first connection hole 10 is provided in the boss 14, so that the boss 14 can block liquid from entering the first connection hole 10, the liquid is prevented from flowing into the inside of the battery device through the first connection hole 10, and the liquid can be prevented from flowing onto the single battery.

Illustratively, as shown in fig. 1 and 2, the drainage channel 11 is disposed around the boss 14, at the root of the boss 14. The drainage channel 11 can collect liquid and guide the liquid to be discharged, so as to play a role in dredging; the boss 14 is higher than the water drainage tank 11, can prevent that liquid from getting into first connecting hole 10 in, plays the blocking effect, and both can make liquid discharge battery device outside along the drainage runner 12 of design fast through the cooperation of blocking up and mediation, effectively prevent that liquid from producing the corruption to battery device internals.

Illustratively, as shown in fig. 1 and 3, the aperture of the second connection hole 20 of the cover plate 2 is larger than the radial dimension of the boss 14, and the boss 14 passes through the second connection hole 20. Thus, when liquid seeps from the edge of the second connecting hole 20, the liquid can directly fall into the drainage groove 11 at the periphery of the boss 14, and the liquid can be further prevented from flowing into the first connecting hole 10.
