Bracket body, bracket, battery unit and energy storage power supply
A bracket body, a bracket, a battery unit, and an energy storage power supply are provided. The bracket includes a base shell and a stopper, wherein the base shell is provided with a receiving groove for receiving a battery cell, the receiving groove runs through a first surface and a second surface of the base shell, and the first surface and the second surface are two opposite surfaces of the base shell; the stopper includes a connecting part and a resisting part, the connecting part is fixed to the first surface of the base shell and avoids the receiving groove, and the resisting part is connected to the connecting part; and the resisting part corresponds to the receiving groove and covers part of an edge of the receiving groove.
1 . A bracket, comprising:
a first bracket body and a second bracket body;
wherein the second bracket body rotates relative to the first bracket body in a mirroring mode in a predetermined direction, and is fixed to the first bracket body in a laminating mode; and
each of the first bracket body and the second bracket body comprises:
a base shell, the base shell being provided with a receiving groove for receiving a battery cell, the receiving groove running through a first surface and a second surface of the base shell, and the first surface and the second surface being two opposite surfaces of the base shell;
a first stopper comprising a first connecting part and a first resisting part, the first connecting part being fixed to the first surface of the base shell and avoiding the receiving groove, the resisting part being connected to the first connecting part, and the resisting part corresponding to the receiving groove and covering a part of an edge of the receiving groove, wherein the first stopper is integrally formed with the base shell, and
a second stopper comprising a second connecting part and two resisting parts, the second connecting part being fixed to the first surface of the base shell and avoiding the receiving groove, the two resisting parts being connected to the second connecting part, and the two resisting parts corresponding to the receiving groove and covering a part of an edge of the receiving groove, wherein the second stopper is integrally formed with the base shell, wherein
the first resisting part, and the two resisting parts are higher than the first surface of the base shell and form a gap with the first surface;
the first surface of the base shell is mounted by a planar conductive sheet,
the planar conductive sheet is provided with a plurality of positioning holes, and positions, shapes and sizes of the plurality of positioning holes correspond to the first stopper and the second stopper; wherein the plurality of positioning holes play a positioning role when the planar conductive sheet is mounted on the first surface, so as to prevent the deviation of a mounting position from affecting the welding effect,
the battery cell is installed in the receiving groove, and the resisting parts of the bracket body are abutting against a part of an edge at one end of the battery cell to prevent the battery cell from sliding out of the bracket body from the first surface;
wherein the receiving groove of the first bracket body and the receiving groove of the second bracket body are connected for receiving one battery cell, and the stoppers of the first bracket body and the stoppers of the second bracket body are respectively arranged at opposite ends.
2 . The bracket according to claim 1 , wherein the base shell is provided with a plurality of receiving grooves arranged in a honeycomb pattern.
3 . The bracket according to claim 2 , wherein the stopper comprises the connecting part and at least one resisting part, and each of the at least one resisting part corresponds to and covers the part of the edge of one receiving groove of the plurality of receiving grooves.
4 . The bracket according to claim 1 , wherein a height of the gap is 0.3-0.8 mm.
5 . The bracket according to claim 1 , wherein the first stopper is L-shaped and the second stopper is T-shaped.
