Abstract
Description
Technical Field
[0001] This utility model belongs to the field of soft-pack battery technology, and in particular relates to a soft-pack battery holder. Background Technology
[0002] In the cell assembly process of pouch batteries, the pouch cells are assembled in a stacked manner. Individual pouch cells are unsupported and are fixed by being surrounded by the outer shell. This poses a safety hazard due to insufficient support for the pouch cells. Furthermore, because the pouch cells are fixed by being surrounded by the outer shell, the electrode plates are welded to the aluminum busbar at the top, which is inconvenient to operate during welding and affects assembly efficiency. Summary of the Invention
[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a soft-pack battery bracket, which supports the soft-pack battery cells for arrangement and assembly. It enables the electrode plates of the soft-pack battery cells to be laterally welded to the aluminum strips in the side welding notch of the bracket, thereby improving welding convenience and assembly efficiency.
[0004] Technical solution: To achieve the above objectives, this utility model provides a soft-pack battery holder, which includes a holder, and soft-pack battery cells are stacked and arranged to form a soft-pack battery cell module through the holder for support. The soft-pack battery cells are embedded in the holder.
[0005] The bracket has a side welding notch for aluminum busbars on one side. The electrode sheet of the soft-pack battery cell extends horizontally to the side welding notch and contacts the aluminum busbar, so that the electrode sheet and the aluminum busbar can be welded together in the side position.
[0006] Furthermore, two soft-pack battery cells are embedded in the same bracket, forming a dual-cell module segment, and several dual-cell module segments are stacked to form the soft-pack battery cell module.
[0007] Furthermore, the electrode plates of the two soft-pack battery cells within the same bracket are bonded together from both sides of the aluminum busbar and then fixed by welding.
[0008] Furthermore, a wiring groove is provided at the center of the side welding notch, and the two aluminum busbars on the same bracket are arranged symmetrically about the wiring groove.
[0009] Furthermore, the bracket has a cover plate corresponding to the side welding notch, the cover plate closing over the opening of the side welding notch to cover and shield the aluminum busbar.
[0010] Furthermore, the cover plate is aligned with the opening edge of the side welding notch to cooperate with the bracket to form a frame structure with a closed outer contour.
[0011] Furthermore, the inner wall of the bracket is covered with a silicone gasket, and the soft-pack battery cell is embedded in the bracket by extruding the silicone gasket.
[0012] Furthermore, the bracket is provided with positioning plugs and positioning holes on both sides in the stacking assembly direction. When assembling the soft-pack battery cell module, the adjacent dual-cell module segments are positioned by coaxial insertion of the positioning plugs and positioning holes.
[0013] Furthermore, the bracket is provided with mounting holes, and each bracket is fixed in series by a screw passing through the mounting hole.
[0014] Beneficial effects: This utility model utilizes a bracket to support the soft-pack battery cells for arrangement and assembly, which can improve the support stability of the individual soft-pack battery cells, ensure the stability of their assembly, and enable the electrode plates of the soft-pack battery cells to be laterally welded to the aluminum strips in the side welding notch of the bracket, making welding more convenient. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of the overall structure of this utility model;
[0016] Figure 2 A structural diagram of the bracket, pouch cell, and cover plate. Detailed Implementation
[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] like Figure 1 and Figure 2 As shown, a pouch battery holder includes a holder 1. Pouch cells 2 are stacked and arranged to form a pouch cell module, supported by the holder 1. The pouch cells 2 are embedded in the holder 1. One side of the holder 1 has a side welding notch 3 for aluminum busbars 4. The electrode plates 20 of the pouch cells 2 extend horizontally towards the side welding notch 3 and contact the aluminum busbars 4, allowing the electrode plates 20 and the aluminum busbars 4 to be welded together laterally. This invention utilizes the holder 1 to support the pouch cells for arrangement and assembly, which improves the support stability of the individual pouch cells 2, ensures the stability of their assembly, and enables lateral welding of the electrode plates 20 of the pouch cells 2 to the aluminum busbars 4 within the side welding notch 3 of the holder 1, making welding more convenient.
[0019] Two soft-pack battery cells 2 are embedded within the same bracket 1, forming a dual-cell module segment. Several dual-cell module segments are stacked to form the soft-pack battery module. More specifically, the electrode plates 20 of the two soft-pack battery cells 2 within the same bracket 1 are connected and fixed by welding after being brought into contact from both sides of the aluminum busbar 4. The bracket 1 is provided with positioning plugs 8 and positioning holes 9 on both sides in the stacking assembly direction. When assembling the soft-pack battery module, adjacent dual-cell module segments are positioned by coaxial insertion of the positioning plugs 8 and positioning holes 9. The bracket 1 is provided with mounting holes 10, and each bracket 1 is fixed in series by screws 11 passing through the mounting holes 10. After a single dual-cell module segment is manufactured, several dual-cell module segments can be connected in series and fastened by screws 11, making assembly more convenient and efficient.
[0020] To facilitate the routing of the wire harness, a routing groove 5 is provided in the middle of the side welding notch 3, and the two aluminum busbars 4 on the same bracket 1 are arranged symmetrically about the routing groove 5.
[0021] The bracket 1 has a cover plate 6 corresponding to the side welding notch 3. The cover plate 6 covers the opening of the side welding notch 3 to cover and shield the aluminum busbar 4, thereby improving safety. More specifically, the cover plate 6 is slidably connected relative to the thickness direction of the bracket 1, thereby ensuring that the end edge of the cover plate 6 is aligned with the opening of the side welding notch 3, so as to cooperate with the bracket 1 to form a frame structure with a closed outer contour, thereby improving the structural regularity.
[0022] like Figure 2 As shown, the inner wall of the bracket 1 is covered with a silicone gasket 7, which protrudes slightly from the inner wall of the bracket 1. The soft-pack battery cell 2 is embedded in the bracket 1 by squeezing the silicone gasket 7.
[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
