Abstract

Claims (21)

1 . A battery box, comprising:

a box body enclosing a chamber for accommodating a battery cell; and

a first position-limit structure disposed on a side of a first wall of the box body opposite from the battery cell, wherein the first wall is perpendicular to a first direction, after the box body is mounted on an electrical apparatus, the first direction is parallel to a traveling direction of the electrical apparatus, and the first position-limit structure is used to limit a relative displacement of the battery box to the electrical apparatus in the first direction, the first wall comprising an extending structure, the extending structure extending away from the battery cell along the first direction, and the extending structure being used for arrangement of a second position-limit structure;

wherein the first position-limit structure and the second position-limit structure are both disposed on the first wall of the box body and the first position-limit structure and the second position-limit structure are adjacently arranged, the first position-limit structure being disposed in a first region of the first wall, and the second position-limit structure being disposed on the extending structure,

the first position-limit structure comprises: a first position-limit block and a buffer block, the first position-limit block is disposed on the first wall and is capable of moving along the first direction, the buffer block is disposed between the first position-limit block and the first wall, and the buffer block is used to provide a buffer distance of the first position-limit block in the first direction,

the first wall of the box body contains a recess to accommodate the first position-limit block and the buffer block, and in the first direction, a depth of the recess is greater than a thickness of the buffer block, and

the battery box further includes a locking structure, which is disposed on a side of the first wall of the box body away from the battery cell, the locking structure is configured to secure or release the battery box to the electrical apparatus, and the first position-limit structure is disposed adjacent to the locking structure.

2 . The battery box according to claim 1 , wherein the battery box further comprises:

the second position-limit structure disposed on a side of the box body opposite from the battery cell and used to limit a relative displacement of the battery box to the electrical apparatus in a second direction, wherein the second direction is parallel to the direction of gravity after the battery box is mounted on the electrical apparatus.

3 . The battery box according to claim 2 , wherein the second position-limit structure is an elastic position-limit block, and the elastic position-limit block is compressed to abut against the electrical apparatus after the battery box is mounted on the electrical apparatus.

4 . The battery box according to claim 3 , wherein a first end of the elastic position-limit block is provided with a chamfer structure, and the first end of the elastic position-limit block is an end of the elastic position-limit block facing toward the opposite direction of gravity.

5 . The battery box according to claim 2 , wherein the center of the first position-limit structure and the center of the second position-limit structure are located on a first plane, and the first plane is parallel to a plane defined by the first direction and the second direction.

6 . The battery box according to claim 1 , wherein the first position-limit structure further comprises: a first fastener, the first position-limit block is disposed on the first wall through the first fastener, and the first fastener is used to provide a buffer space of the first position-limit block and the buffer block in the first direction.

7 . The battery box according to claim 1 , wherein a first end of the first position-limit block is provided with an angle between a surface of the first wall and a surface of the first position-limit block, and the first end of the first position-limit block is an end of the first position-limit block facing toward the opposite direction of gravity.

8 . The battery box according to claim 1 , wherein the first wall is provided with an accommodating area, the accommodating area being used for accommodating the first position-limit structure.

9 . The battery box according to claim 1 , wherein the battery box comprises a plurality of first position-limit structures, the plurality of first position-limit structures being distributed on two first walls of the box body that are parallel to each other.

10 . A battery, comprising: a battery cell and the battery box according to claim 1 , wherein the battery box is used for accommodating the battery cell.

11 . An electrical apparatus, comprising: the battery according to claim 10 .

12 . The battery box according to claim 1 , wherein there is an empty space between a bottom surface of the recess and an end surface of the first position-limit block facing the first wall in the first direction.

13 . The battery box according to claim 1 , wherein in a second direction perpendicular to the first direction, a width of the first position-limit block is longer than that of the buffer block.

14 . The battery box according to claim 1 , wherein the first position-limit structure further comprises a first fastener, the first position-limit block is disposed on the first wall through the first fastener, and an end surface of the first fastener away from the first wall is closer to the bottom surface of the recess than an end surface of the first position-limit block away from the first wall in the first direction.
