Abstract

Embodiments of the application provide a fixing member, a battery, an electric device, a battery, and a method and system for manufacturing the battery. The fixing member according to an embodiment of the application is used for fixing a workpiece, and comprises a base for connecting an external pedestal; a top cover connected to the base, an accommodating groove for accommodating the workpiece being formed between the base and the top cover; a first elastic member arranged between the top wall and the bottom wall of the accommodating groove; and a second elastic member arranged between two inner side walls of the accommodating groove. The fixing member according to an embodiment of the application can reduce the shaking of the workpiece and improve the stability of the battery.

First claim

What is claimed is:

1 . A fixing member for fixing a workpiece, comprising:
a base for connecting an external pedestal; a top cover connected to the base, an accommodating groove for accommodating the workpiece being formed between the base and the top cover; a first elastic member arranged between the top wall and the bottom wall of the accommodating groove, and configured to abut against the workpiece in a first direction to fix the workpiece between the top wall and the bottom wall; and a second elastic member arranged between two inner side walls of the accommodating groove, and configured to abut against the workpiece in a second direction to fix the workpiece between the two inner side walls of the accommodating groove, with the first direction intersecting with the second direction.

2 . The fixing member according to claim 1 , wherein the top cover comprises a body portion, an inner wall, facing the base, of the body portion is configured to constitute at least part of the top wall, and the first elastic member is arranged on the body portion of the top cover.

3 . The fixing member according to claim 2 , wherein the first elastic member comprises:
a first elastic portion connected to the body portion of the top cover; and a first abutting portion connected to one end, facing away from the body portion, of the first elastic portion; in the first direction, the first abutting portion and the bottom wall are arranged at intervals, and the first abutting portion is configured to abut against the workpiece to fix the workpiece between the first abutting portion and the bottom wall.

4 . The fixing member according to claim 3 , wherein at least part of the first elastic portion is arc-shaped.

5 . The fixing member according to claim 4 , wherein the first elastic member comprises at least two first elastic portions arranged at intervals in the second direction; and
in the first direction, the two first elastic portions are located between the first abutting portion and the body portion.

6 . The fixing member according to claim 5 , wherein the first elastic portion comprises:
a first base portion connected to a surface, facing the body portion, of the first abutting portion, and having two first surfaces arranged opposite to each other in the thickness direction thereof; a first supporting portion connecting the body portion and one end, facing away from the first abutting portion, of the first base portion; a first protrusion portion protruding from the first surface of the first base portion; and a second supporting portion connecting the first protrusion portion and the body portion, the first supporting portion and the second supporting portion being arranged at intervals in a third direction which intersects with both the first direction and the second direction.

7 . The fixing member according to claim 6 , wherein,
the two inner side walls of the accommodating groove are a first inner side wall and a second inner side wall respectively which are arranged opposite to each other in the second direction; the second elastic member comprises: a second elastic portion, with one end connected to the first inner side wall; a second abutting portion connected to the other end, facing away from the first inner side wall, of the second elastic portion; in the second direction, the second abutting portion and the second inner side wall are arranged at intervals, and the second abutting portion is configured to abut against the workpiece to fix the workpiece between the second abutting portion and the second inner side wall.

8 . The fixing member according to claim 7 , wherein a groove is formed on the base and constitutes at least part of the accommodating groove.

9 . The fixing member according to claim 8 , wherein,
the base comprises a bottom plate, and a first limiting part and a second limiting part connected thereto, the first limiting part and the second limiting part are arranged at intervals in the second direction, the bottom plate, the first limiting part and the second limiting part form the groove; and one end of the top cover is clamped to the first limiting part, and/or the other end thereof is clamped to the second limiting part.

10 . The fixing member according to claim 9 , wherein,
one end of the top cover is clamped to the first limiting part, and the other end thereof is rotatably connected to the second limiting part through a connecting member.

11 . The fixing member according to claim 10 , wherein,
the connecting member comprises a deformation portion rotatably connected to the second limiting part, and a connecting portion connected to the deformation portion and the top cover and provided with a backstop portion; the base is provided with a first convex rib protruding from the second limiting part; when the top cover is clamped to the first limiting part, the first convex rib fits with the backstop portion to limit the movement of the connecting portion in the first direction away from the base.

12 . The fixing member according to claim 11 , wherein the base is further provided with a second convex rib protruding from the second limiting part, and the second convex rib fits with the connecting portion to limit the movement of the connecting portion in a direction towards the second limiting part.

13 . The fixing member according to claim 12 , wherein the first convex rib and the second convex rib are integrally formed.

14 . The fixing member according to claim 13 , wherein the connecting portion is provided with a first through hole, the backstop portion is formed on one side, close to the deformation portion, of the first through hole, and the first convex rib is inserted into the first through hole to fix with the backstop portion when the top cover is clamped to the first limiting part.

15 . The fixing member according to claim 14 , wherein the backstop portion is connected to an end, facing away from the second limiting part, of the deformation portion;
the connecting portion further comprises: a second protrusion portion protruding from the surface, facing the second limiting part, of the backstop portion; a first extension portion connecting the top cover and one end, facing away from the deformation portion, of the backstop portion; and a second extension portion connecting the second protrusion portion and the top cover, the first extension portion and the second extension portion are arranged at intervals in a third direction which intersects with both the first direction and the second direction, and the first through hole is formed between the first extension portion and the second extension portion.

16 . The fixing member according to claim 15 , wherein the first limiting part comprises a limiting plate, and a clamping seat connected to the limiting plate and located at one side, away from the second limiting part, of the limiting plate, and a clamping slot is formed between the limiting plate and the clamping seat;
the top cover comprises a buckling portion used for being inserted into the clamping slot and clamped to the clamping seat.

17 . The fixing member according to claim 16 , wherein,
the buckling portion comprises a first clamping portion and a second clamping portion, both arranged in a third direction which intersects with both the first direction and the second direction; the clamping seat comprises a third clamping portion and a fourth clamping portion which are arranged in the third direction; when the buckle is clamped to the clamping seat, the first clamping po
