Abstract

A battery pack and an output end protection support are provided. The battery pack includes a box body, a first output end protection support, and a second output end protection support. The first output end protection support is arranged on the box body. The second output end protection support is arranged on the box body. The first output end protection support is directly connected to the second output end protection support, and the first output end protection support and the second output end protection support are movably arranged relative to each other.

Claims (22)

1 . A battery pack, comprising:

a box body;

a first output end protection support, wherein the first output end protection support is arranged on the box body;

a second output end protection support, wherein the second output end protection support is arranged on the box body, the first output end protection support is slidably connected to the second output end protection support and directly contacts the second output end protection support, and the first output end protection support and the second output end protection support are movably arranged relative to each other;

a first battery assembly, wherein the first battery assembly comprises a first output pole, and the first output pole is connected to the first output end protection support;

a second battery assembly, wherein the second battery assembly comprises a second output pole, and the second output pole is connected to the second output end protection support; and

a conductive member, wherein the conductive member is connected to the first output pole and the second output pole,

wherein the first output end protection support is provided with a slot, the second output end protection support is provided with a slide block, and the first output end protection support and the second output end protection support are connected through the slot and the slide block.

2 . The battery pack according to claim 1 , wherein the first output end protection support is provided with a first connection portion, and the second output end protection support is provided with a second connection portion, and the battery pack further comprising:

a first fastener, wherein the first fastener passes through the conductive member and the first output pole, and is connected to the first connection portion; and

a second fastener, wherein the second fastener passes through the conductive member and the second output pole, and is connected to the second connection portion.

3 . The battery pack according to claim 2 , wherein the first connection portion is a first threaded hole, the second connection portion is a second threaded hole, the first fastener is a first bolt, and the second fastener is a second bolt.

4 . The battery pack according to claim 1 , wherein the first output end protection support and the second output end protection support are movably arranged relative to each other in a set direction on a plane parallel to a bottom plate of the box body, and the set direction is perpendicular to an arrangement direction of the first output end protection support and the second output end protection support.

5 . The battery pack according to claim 1 , wherein the box body comprises:

a bottom plate; and

a main frame, wherein the main frame is disposed on the bottom plate to form a battery accommodating space;

wherein the first output end protection support and the second output end protection support are adjacent to the main frame, and the first output end protection support and the second output end protection support are both movably arranged along the main frame.

6 . The battery pack according to claim 5 , wherein the main frame comprises:

a frame, wherein the frame is arranged around the bottom plate to form the battery accommodating space; and

a partition beam, wherein the partition beam is arranged in the frame to separate the battery accommodating space;

wherein the partition beam is formed with a cavity, one end of the first output end protection support is inserted into the cavity, and one end of the second output end protection support is inserted into the cavity, such that the first output end protection support and the second output end protection support are limited to move in a direction perpendicular to an upper surface of the partition beam.

7 . The battery pack according to claim 6 , wherein the partition beam is provided with a recessed portion, and both the first output end protection support and the second output end protection support are located in the recessed portion.
