电池包的箱体、电池包及用电设备

Abstract

本公开涉及一种电池包的箱体、电池包及用电设备，该电池包的箱体包括边框、盖板、底板和内部梁，底板和盖板分别连接于边框的第一方向上的相对的两端，以围成腔体，内部梁设置在腔体内，以将腔体分隔为至少两个容纳腔，内部梁在第一方向上分别抵接于底板和盖板，内部梁具有面向相邻的容纳腔的第一侧面，至少一个第一侧面与底板或盖板之间连接有第一密封件，第一密封件用于密封对应的第一侧面于底板或盖板的交界处，这样，可以在箱体内部对内部梁和盖板的交界处或者内部梁和底板的交界处进行密封，密封效果好，且无需相关技术中贯穿盖板或底板的螺栓等，更经久耐用。

Claims

1. A battery pack case characterized by comprising: The device includes a frame, a cover plate, a bottom plate, and an internal beam.

The internal beam has a first side facing the adjacent receiving cavity. At least one of the first side faces the bottom plate or the cover plate and is connected to a first seal. The first seal is used to seal the junction of the corresponding first side with the bottom plate or the cover plate.

2. The battery pack case according to claim 1, characterized by, The housing also includes a limiting member, one end of which is connected to the first side and the other end of which is connected to the bottom plate or the cover plate, so as to form a limiting cavity with the first side and the bottom plate or the cover plate. The limiting cavity is provided with the first sealing member, and the limiting cavity is used to limit the position of the first sealing member.

3. The battery pack case according to claim 2, characterized by, The limiting member is connected between the internal beam and the bottom plate, and the internal beam and / or the bottom plate are provided with a limiting structure; or, the limiting member is connected between the internal beam and the cover plate, and the internal beam and / or the cover plate are provided with a limiting structure. The limiting structure cooperates with the limiting member to limit the position of the limiting member.

4. The battery pack case according to claim 3, characterized by, The limiting structure includes a limiting groove, and the limiting member is inserted into the limiting groove.

5. The battery pack case of claim 2, wherein, The limiting member connects the internal beam and the base plate, and the limiting member is integrally formed with the internal beam or the base plate; or... The limiting member is connected between the internal beam and the cover plate, and the limiting member is integrally formed with the internal beam or the cover plate.

6. The battery pack case according to any one of claims 2 to 5, characterized by, The first seal includes a first colloid filling the limiting cavity.

7. The battery pack case according to claim 6, characterized by, The limiting cavity is provided with a connecting structure, which is connected to the first colloid and also connected to the internal beam, the bottom plate, or the cover plate that surrounds the limiting cavity.

8. The battery pack case according to claim 7, characterized by, The connection structure includes protrusions and / or grooves.

9. The battery pack case of claim 8, wherein, The protrusion extends perpendicular to the first direction and parallel to the first side. The protrusion has multiple ventilation channels spaced apart in its own extension direction. The ventilation channels extend perpendicular to the extension direction of the protrusion to penetrate the protrusion.

10. The battery pack case of claim 6, wherein, The limiting member is provided with a through hole connecting the limiting cavity and the receiving cavity, and the through hole serves at least as an vent hole and / or a glue-filling hole and / or an observation hole.

11. The battery pack case of claim 10, wherein, The internal beam has a cavity, and the internal beam is provided with a connecting hole that connects the cavity and the limiting cavity.

12. The battery pack case according to any one of claims 1 to 5, characterized by, One of the internal beam and the base plate has a first recessed portion facing away from the other, and a second sealing element for sealing the space between the base plate and the internal beam is provided in the first recessed portion; and / or Either the internal beam or the cover plate has a second recess that is opposite to the other, and a second seal is provided in the second recess for sealing the space between the cover plate and the internal beam.

13. The battery pack case of claim 12, wherein, The internal beam has a first recessed portion facing away from the base plate, and the base plate has a first protrusion that inserts into the first recessed portion. A first gap is formed between the first recessed portion and the first protrusion, and the second seal fills the first gap; and / or The internal beam is provided with a second recessed portion facing away from the cover plate, and a second protrusion is formed on the cover plate that is inserted into the second recessed portion. A second gap is formed between the second recessed portion and the second protrusion, and the second seal is filled in the second gap.

14. The battery pack box of claim 13, wherein, The second seal includes a second colloid.

15. A battery pack, characterized by The housing includes a battery cell and a battery pack as described in any one of claims 1-14, wherein at least one of the receiving cavities contains the battery cell.

16. An electrical device, characterized by Includes the battery pack as described in claim 15.
