Battery pack and electric apparatus
A battery pack and an electric apparatus are disclosed. The battery pack includes a cell dummy and multiple battery cells, a housing, a mounting beam, and a support beam. The housing is provided with an accommodating cavity, and the cell dummy and the multiple battery cells are all disposed in the accommodating cavity. The mounting beam is disposed in a length direction of the accommodating cavity and defines, together with the accommodating cavity, a mounting space for accommodating the cell dummy and the multiple battery cells. The support beam is disposed in a width direction of the accommodating cavity and is mounted in a manner of fitting with the cell dummy. The cell dummy being provided with the support beam perpendicular to the mounting beam can enhance structural strength of the battery pack in the width direction of the accommodating cavity.
1. A battery pack, comprising:
a cell dummy and a plurality of battery cells;
a housing provided with an accommodating cavity, wherein the cell dummy and the plurality of battery cells are configured to be disposed in the accommodating cavity;
a mounting beam, disposed in one direction of the accommodating cavity and defining, together with the accommodating cavity, a mounting space for accommodating the cell dummy and the plurality of battery cells; and
a support beam, disposed in the other direction of the accommodating cavity and configured to fit within the cell dummy.
2. The battery pack according to claim 1 , wherein the support beam is configured to extend extends-out of the cell dummy.
3. The battery pack according to claim 2 , wherein the support beam is disposed independently of the cell dummy.
4. The battery pack according to claim 2 , wherein a mounting hole is configured to run through the cell dummy, and the support beam is disposed in the mounting hole and configured to extend out of two ends of the mounting hole.
5. The battery pack according to claim 4 , wherein the plurality of battery cells each comprises a pole extending toward the other direction of the accommodating cavity, and a portion of the support beam extending out of the cell dummy is higher than a portion of the pole extending out of the battery cell.
6. The battery pack according to claim 3 , wherein the support beam and the mounting beam are integrally formed, and the support beam is disposed in a mounting hole of the cell dummy.
7. The battery pack according to claim 2 , wherein the support beam and the cell dummy are integrally formed.
8. The battery pack according to claim 2 , wherein the support beam is configured to abut against the mounting beam.
9. The battery pack according to claim 2 , wherein a gap is present between the support beam and the mounting beam.
10. The battery pack according to claim 1 , wherein the cell dummy and the plurality of battery cells are stacked in the mounting space.
11. The battery pack according to claim 1 , wherein in the one direction of the accommodating cavity, two sides of the cell dummy are each provided with one battery cell.
12. The battery pack according to claim 11 , wherein in the other direction of the accommodating cavity, the cell dummy is disposed adjacent to a bottom of the accommodating cavity.
13. An electric apparatus, comprising the battery pack according to claim 1 , wherein the battery pack is configured to provide electrical energy.
