[0033] In the related art, the quick plug-in is fixed on the upper cover of the box body. When the connecting wire of the battery pack is connected to the quick plug-in, the upper cover has not yet covered the base, so a longer connecting wire is required to connect the quick plug-in. After the connection is completed, the upper cover with the quick plug-in is covered on the base and the upper cover is fixed with screws. However, after the upper cover is covered, the longer wires will be pressed into the box body, which is prone to wire pressing problems. Moreover, after the upper cover is covered, the connecting wires in the box body cannot be sorted out, resulting in problems such as messy wiring of the connecting wires, which may cause damage to the connecting wires in the battery pack, which will have a greater impact on the safety of the battery pack.

[0034] See also Figures 1 to 5 The utility model provides a quick plug assembly 100 for a battery pack 200. The quick plug assembly 100 includes a battery cell baffle 12 and a quick plug 14. A mounting seat 16 is provided on the battery cell baffle 12. The quick plug 14 is mounted on the mounting seat 16.

[0035] In the above-mentioned quick-connect assembly 100, a mounting seat 16 is provided on the battery cell baffle 12, so that after the battery cell is fixed by the battery cell baffle 12, the quick-connect plug 14 can be installed on the mounting seat 16, which not only does not affect the assembly of the battery cell, but also can fix the quick-connect plug 14 in advance to avoid the risk of wire crimping inside the battery pack 200.

[0036] Specifically, please combine Figures 3 to 5The battery pack 200 includes a box body 18, a plurality of battery cells 20 and a current collecting component 22. The current collecting component 22 is disposed on the top of the plurality of battery cells 20 and connected to the poles of the battery cells 20.

[0037] Optionally, the box body 18 includes a base 24 and a cover 26. The base 24 is provided with a receiving cavity 28. The top of the base 24 has an opening 30, and the opening 30 is connected to the receiving cavity 28. The battery cell 20 and the current collecting component 22 can be located in the receiving cavity 28. Figure 4 As shown, the left and right directions of the battery cells 20 are arranged in the accommodating cavity 28, and the multiple battery cells 20 can be connected in series, in parallel, or in mixed connection through the converging component 22. Mixed connection means that the multiple battery cells 20 are connected in series or in parallel.

[0038] The cover plate 26 may be disposed at the top opening 30 of the base 24 to seal the accommodating cavity 28. The base 24 and the cover plate 26 may be fixed to each other by means of, but not limited to, fasteners 32 (such as screws), snaps, and the like. Figures 3 to 5 In the embodiment, the base 24 and the cover 26 are fixedly connected by screws.

[0039] A plurality of battery cells 20 are arranged in a first direction to form a battery cell row. Figures 3 to 5 In the embodiment, the first direction is the front-to-back direction, the second direction is the left-to-right direction, and the third direction is the up-down direction. The cell baffle 12 can fix the cell 20 on one side of the cell row along the first direction and prevent the cell 20 from swelling. Figure 5 In the embodiment, the cell baffle 12 fixes the cell row at the front side of the cell row, and the cell row can be fixed between the rear side wall of the accommodating cavity 28 and the cell baffle 12. It can be understood that in other embodiments, the first direction is not limited to the front-to-back direction, the second direction is not limited to the left-to-right direction, and the third direction is not limited to the up-down direction.

[0040] The cell baffle 12 is insulated. Optionally, the cell baffle 12 is made of an insulating material (such as plastic). Optionally, the cell baffle 12 may be formed with an insulating layer on the surface of the substrate. The substrate may be insulating or conductive.

[0041] Optionally, the mounting seat 16 and the cell baffle 12 may be an integral structure or a separate structure. When the mounting seat 16 and the cell baffle 12 are an integral structure, the cell baffle 12 with the mounting seat 16 may be directly manufactured using manufacturing equipment. For example, the cell baffle 12 with the mounting seat 16 may be manufactured using an injection molding process using an injection molding tool and plastic, thereby forming an integral mounting seat 16 and a cell baffle 12.

[0042] When the mounting base 16 and the cell baffle 12 are separate structures, the mounting base 16 and the cell baffle 12 can be manufactured separately and then fixed together. The fixing methods include but are not limited to screw fixing, welding, snap-fitting and the like.

[0043] When assembling the battery pack 200, after multiple battery cells 20 are loaded into the accommodating cavity 28, the battery cell baffle 12 can be used to fix the battery cell row on one side of the battery cell row. Since the mounting seat 16 of the quick plug-in 14 is integrated on the battery cell baffle 12, the quick plug-in 14 can be installed on the mounting seat 16 after the battery cell baffle 12 is fixed. At this time, the quick plug-in 14 is closer to the battery cell 20, and the length of the connecting wire can be shorter. After the connecting wire and the quick plug-in 14 are connected, the connecting wire can be arranged in order, and then the cover plate 26 is assembled to the base 24 and fixed, so that the problem of wire pressing and the disorderly wiring of the connecting wire can be avoided or reduced to a certain extent, thereby improving the safety of the battery pack 200.

[0044] Moreover, the battery pack 200 can be fully tested through the quick plug-in 14 before the final assembly of the cover plate 26, and relevant problem points can be tested to improve production efficiency and avoid short-circuit safety hazards. It is also possible to reduce the cumulative dimensional tolerance of the quick plug-in 14 assembly, making the assembly dimensions of the quick plug-in 14 more stable, and improving production yield and efficiency. At the same time, since the connecting wires are shortened, the space occupied by the connecting wires in the box 18 can be reduced, so that more battery cells 20 can be placed in the box 18, thereby improving the overall energy density of the battery pack 200 to a certain extent.

[0045] In summary, fixing the quick connector 14 to the relatively movable cell baffle 12 not only does not affect the assembly of the cell 20 , but also can fix the connector in advance and improve the overall energy density of the battery pack 200 , which is particularly friendly to the space utilization of the compact battery pack 200 .

[0046] In some embodiments, the cell baffle 12 includes a first baffle 34 , a second baffle 36 and a third baffle 38 , the third baffle 38 connects one side of the first baffle 34 and one side of the second baffle 36 , and the mounting seat 16 is disposed on the third baffle 38 .

[0047] Thus, the battery cell 20 can be blocked by the three blocking members.

[0048] Specifically, the first stopper 34 and the second stopper 36 are arranged in a spaced relationship along the second direction, and the third stopper 38 connects one side of the first stopper 34 along the third direction and one side of the second stopper 36 along the third direction. Figure 1 In the embodiment, the second direction is the left-right direction, and the third direction is the up-down direction, that is, the first stopper 34 and the second stopper 36 are arranged at intervals along the left-right direction, and the third stopper 38 connects the top of the first stopper 34 and the top of the second stopper 36, so that the first stopper, the second stopper 36 and the third stopper 38 form a through space 39, and the connecting line can extend from the battery cell 20 side to the fast plug-in unit 14 side through the through space 39, and can be connected to the battery management system of the battery pack 200, thereby saving space.

[0049] The first stopper 34 , the second stopper 36 and the third stopper 38 may be connected to form an integral structure or may be a separate structure.

[0050] exist Figure 1 and Figure 2 In the embodiment, the mounting seat 16 is disposed on the top of the third stopper 38 , so as to facilitate the connection between the quick plug-in 14 and other battery packs 200 .

[0051] In some embodiments, a mounting portion 40 is provided on the third stopper 38 , and the mounting portion 40 is suitable for fixing the battery cell baffle 12 in the box body 18 of the battery pack 200 .

[0052] In this way, the cell baffle 12 can be conveniently fixed.

Figure 1 In the embodiment, the first direction is the front-to-back direction, and a mounting portion 40 is provided on the front side of the third stopper 38. The mounting portion 40 may protrude forwards compared to the third stopper 38, thereby facilitating the installation of the cell baffle 12.

[0054] A mounting post 42 is provided in the accommodating cavity 28 . After the cell baffle 12 is placed in the accommodating cavity 28 , the mounting post 42 is correspondingly connected to the mounting portion 40 . The mounting portion 40 can be fixed to the mounting post 42 by fasteners 32 (such as screws), thereby achieving installation and fixation of the cell baffle 12 .

[0055] In some embodiments, the mounting seat 16 is provided with a mounting hole 44 , and the quick-plug connector 14 passes through the mounting hole 44 .

[0056] Thus, the quick-install plug-in unit 14 can be easily installed.

[0057] Specifically, the mounting hole 44 passes through the mounting seat 16 along a third direction (such as the up-down direction). The quick plug-in unit 14 can be quickly positioned and installed on the mounting seat 16 through the mounting hole 44, thereby improving the installation efficiency of the quick plug-in unit 14.

[0058] The shape of the mounting hole 44 includes but is not limited to a square, a circle or other regular or irregular shapes. Optionally, the shape of the mounting hole 44 matches the shape of the quick plug-in unit 14 to better limit the position of the quick plug-in unit 14 .

[0059] In some embodiments, a first fixing portion 46 is protruded from the hole wall of the mounting hole 44 , and the quick-plug connector 14 includes a connecting portion 48 and a second fixing portion 50 . The second fixing portion 50 is protruded from the circumferential surface of the connecting portion 48 , and the first fixing portion 46 is connected to the second fixing portion 50 .

[0060] Thus, the quick-connect plug 14 can be fixed on the mounting seat 16 by the first fixing portion 46 and the second fixing portion 50 .

[0061] Specifically, please combine Figure 2 In the embodiment, the quick plug-in unit 14 can be inserted into the mounting hole 44 from top to bottom, the connecting portion 48 passes through the mounting hole 44, the second fixing portion 50 abuts against the first fixing portion 46, and then the first fixing portion 46 and the second fixing portion 50 are fixed by the fastener 32 (such as a screw), thereby achieving the installation and fixation of the quick plug-in unit 14.

[0062] exist Figure 2 In the embodiment, the first fixing portion 46 and the second fixing portion 50 are both ring-shaped, so that the contact area between the first fixing portion 46 and the second fixing portion 50 can be increased, and the installation stability of the quick-plug assembly 14 can be improved to a certain extent.

[0063] In some embodiments, a plug hole 52 is disposed at the top of the connecting portion 48 , and an electrical connector 54 is disposed at the bottom of the connecting portion 48 .

[0064] Thus, the battery pack 200 can be connected to another battery pack 200 via the quick connector 14 .

[0065] Specifically, the energy storage device 300 includes a plurality of battery packs 200, and the plurality of battery packs 200 can be arranged into a battery pack row along a third direction (such as the up and down direction). Each battery pack 200 includes a box body 18 and a socket (not shown), the quick plug-in 14 protrudes from the top of the box body 18, and the socket is recessed in the bottom of the box body 18, and a pin is provided in the socket. When installing the plurality of battery packs 200, they can be installed from bottom to top, that is, the quick plug-in 14 at the top of the lower battery pack 200 is plugged into the socket at the bottom of the upper battery pack 200, and the pin is inserted into the corresponding socket 52 so that the pin is connected to the electrical connector 54, so that the plurality of battery packs 200 can be connected in the up and down direction (including physical connection and electrical connection). The electrical connection mode of the plurality of battery packs 200 can be series connection, parallel connection or mixed connection.

[0066] The electrical connector 54 at the bottom of the connecting portion 48 can be connected to the battery management system and the battery cell 20 via a connecting wire. Figure 2 In the embodiment, the number of electrical connectors 54 is multiple, so as to increase the signal channel and signal bandwidth, etc.

[0067] Please combine Figures 3 to 5 A battery pack 200 according to an embodiment of the present utility model includes a quick-connect assembly 100 according to any of the above embodiments.

[0068] In the above-mentioned battery pack 200, a mounting seat 16 is provided on the cell baffle 12, so that after the cell baffle 12 fixes the cell, the quick plug-in unit 14 can be installed on the mounting seat 16, which not only does not affect the cell assembly, but also can fix the quick plug-in unit 14 in advance, avoiding the risk of wire crimping inside the battery pack 200.

[0069] Specifically, Figures 3 to 5 In the embodiment, the battery pack 200 includes a box body 18, a plurality of battery cells 20 and a current collecting component 22.

[0075] After the cover plate 26 is fixed, the quick plug-in unit 14 protrudes out of the cover plate 26 , thereby facilitating the quick plug-in unit 14 to be plugged into a socket of another battery pack 200 .

[0076] In some embodiments, the battery pack 200 includes a protective member 56 , which is frame-shaped and mounted on the box body 18 and surrounds the fast plug-in unit 14 . The top height of the protective member 56 is equal to or greater than the top height of the fast plug-in unit 14 .

[0077] Thus, the service life of the quick plug-in unit 14 can be extended to a certain extent.

[0078] Specifically, after the battery pack 200 is assembled, the quick connector 14 protrudes from one side of the box body 18, such as the top of the box body 18.
