[0047] The following is combined with Figures 1 to 10 The following describes embodiments of the present invention.

[0048] In a first aspect, according to an embodiment of the present invention, a battery pack 1 is provided. The battery pack 1 has an intersecting first direction Z and a second direction X. The battery pack 1 includes a first housing 100, a cover plate 110, a second housing 120, a battery pack 300, an electrical module 200, and an adapter module 500.

[0049] A cover plate 110 is connected to a first housing 100 along one side of the first direction Z, forming a first receiving cavity 101 with the first housing 100. The cover plate 110 is also connected to a second housing 120 along the other side of the first direction Z, forming a second receiving cavity 102 with the second housing 120. The cover plate 110 has an opening 111 extending along the first direction Z. The first receiving cavity 101 and the second receiving cavity 102 are stacked along the first direction Z and connected through the opening 111. The first housing 100, the cover plate 110, and the second housing 120 are stacked along the first direction Z.

[0050] The battery pack 300 is located in the first receiving cavity 101, and the electrical module 200 is located in the second receiving cavity 102. That is to say, the battery pack 300 and the electrical module 200 are located on opposite sides of the cover plate 110 along the first direction Z.

[0051] The battery pack 300 may include multiple battery cells 310, which may be connected in series or in parallel. The electrical module 200 may include a battery management system (BMS) and a battery distribution unit (BDU). The battery management system is used to manage and maintain the multiple battery cells 310, prevent overcharging and over-discharging of the battery cells 310, extend the service life of the battery cells 310, and monitor the status of the battery cells 310. The battery distribution unit is used to connect to the high-voltage load of the vehicle and the fast charging harness through a high-voltage electrical interface to realize the distribution and management of the energy of the battery cells 310.

[0052] By layering the first receiving cavity 101 and the second receiving cavity 102, i.e., stacking the first receiving cavity 101 and the second receiving cavity 102 along the first direction Z, and separating the first receiving cavity 101 and the second receiving cavity 102 by the cover plate 110, the number of electrical components in the first receiving cavity 101 can be reduced, the number of battery cells 310 that can be arranged in the first receiving cavity 101 can be increased, thereby achieving the purpose of increasing the capacity of the battery pack 1.

[0053] In addition, the first receiving cavity 101 can be filled with expanding foam to improve the strength of the battery pack 1. By setting the first receiving cavity 101 and the second receiving cavity 102 in layers, the electrical module 200 can be prevented from being affected by the expanding foam, and the electrical components in the second receiving cavity 102 can be adjusted and repaired in the future, thereby reducing the cost of using the battery pack 1.

[0054] The battery pack 1 also includes an adapter module 500, which includes an insulating base 510 and an adapter assembly 520. The insulating base 510 is disposed at the opening 111, wherein the insulating base 510 is disposed in the first receiving cavity 101, or the insulating base 510 is disposed in the second receiving cavity 102, or a portion of the insulating base 510 is located in the first receiving cavity 101 and another portion is located in the second receiving cavity 102. The adapter assembly 520 includes an electrical adapter 521, an adapter fixing member 522, and a battery adapter 523. The adapter fixing member 522 is disposed on the insulating base 510. One end of the adapter fixing member 522 is connected to the electrical module 200 through the electrical adapter 521, and the other end is connected to the battery pack 300 through the battery adapter 523. The electrical adapter 521 and the battery adapter 523 are respectively disposed on opposite sides of the insulating base 510 along the first direction Z.

[0055] The adapter fixing component 522 can be integrally injection molded with the insulating base 510 to improve the connection strength between the adapter component 520 and the insulating base 510.

[0056] By setting up the adapter module 500, an electrical connection between the battery pack 300 and the electrical module 200 can be realized. The adapter assembly 520 is divided into a three-section structure, with the electrical adapter 521 located on the side of the insulating base 510 facing the electrical module 200 along the first direction Z, and the battery adapter 523 located on the side of the insulating base 510 facing the battery pack 300 along the first direction Z. This can shorten the length of the electrical adapter 521 and the battery adapter 523, reduce the weight and cost of the electrical adapter 521 and the battery adapter 523, and facilitate the electrical connection between the adapter module 500, the electrical module 200 and the battery pack 300.

[0057] like Figure 7 and Figure 9 As shown, in this embodiment, the insulating base 510 has a mounting surface 801 facing the cover plate 110 along the first direction Z. The orthographic projection of the mounting surface 801 along the first direction Z onto the cover plate 110 covers the opening 111. The battery pack 1 also includes a seal 530 and a connector 540. The seal 530 is compressed between the mounting surface 501 and the cover plate 110. The seal 530 extends circumferentially along the opening 111 and surrounds the opening 111. The connector 540 passes through the cover plate 110 and the mounting surface 501 along the first direction Z and is fixed to the insulating base 510.

[0058] The sealing element 530 can be foam. The sealing element 530 and the insulating base 510 can be connected by adhesive, connector 540, or other means. Alternatively, the insulating base 510 may have a mounting groove (not shown in the figure), and the sealing element 530 may be located in the mounting groove. The connector 540 can be a bolt, which passes through the cover plate 110 and is threadedly engaged with the insulating base 510.

[0059] In this way, the setting of the sealing element 530 can, on the one hand, improve the sealing performance between the insulating base 510 and the cover plate 110, prevent the adhesive in the first receiving cavity 101 from entering the second receiving cavity 102 through the opening 111, and ensure that the electrical module 200 can work normally. On the other hand, it can prevent the insulating base 510 and the cover plate 110 from making hard contact, reducing the probability of damage to the insulating base 510 and the cover plate 110.

[0060] The connector 540 fixes the relative position between the cover plate 110 and the insulating base 510, so that the cover plate 110 and the insulating base 510 clamp the sealing member 530. This not only facilitates the installation and disassembly of the cover plate 110 and the insulating base 510, but also ensures the sealing effect of the sealing member 530 on the gap between the cover plate 110 and the insulating base 510, and more effectively prevents the adhesive in the first receiving cavity 101 from entering the second receiving cavity 102 through the opening 111.

[0061] like Figure 7 , Figure 9 and Figure 10 As shown, in this embodiment, the electrical adapter 521 and the adapter fixing member 522 are detachably connected. That is, the adapter fixing member 522 and the electrical adapter 521 can be separately installed, and they can be connected by snap-fit, bolt connection, or other methods. Specifically, when connecting the insulating base 510 to the first housing 100, the electrical adapter 521 and the adapter fixing member 522 can be left unconnected initially. This facilitates the connection between the insulating base 510 and the first housing 100, reduces the processing difficulty of the adapter assembly 520, improves production efficiency, and facilitates later replacement of the electrical adapter 521, reducing maintenance costs.

[0062] like Figures 8-10 As shown in the technical solution of this embodiment, the battery adapter 523 and the adapter fixing member 522 are detachably connected. That is, the adapter fixing member 522 and the battery adapter 523 can be separately arranged, and the adapter fixing member 522 and the battery adapter 523 can be connected by means of snap-fit, bolt connection, etc. In particular, when the insulating base 510 is connected to the first housing 100, the battery adapter 523 can be left unconnected to the adapter fixing member 522. This facilitates the connection between the insulating base 510 and the first housing 100, reduces the processing difficulty of the adapter assembly 520, improves production efficiency, and facilitates the replacement of the battery adapter 523 later, reducing maintenance costs.

[0063] like Figure 7 , Figures 9-10As shown, in this embodiment, the insulating base 510 is provided with a protective protrusion 511. The protective protrusion 511 protrudes from the mounting surface 501 along the first direction Z. The sealing member 530 has a through hole 531 corresponding to the position of the protective protrusion 511. The protective protrusion 511 passes through the through hole 531, and the protective protrusion 511 encloses a protective cavity 5111. That is, the side of the protective protrusion 511 facing away from the mounting surface 501 is recessed to form the protective cavity 5111. The connection between the adapter fixing member 522 and the electrical adapter member 521 is located inside the protective cavity 5111. That is, the ends of the adapter fixing member 522 and the electrical adapter member 521 are both located inside the protective cavity 5111 and are connected to each other. The cross-section of the protective protrusion 511 can be constructed as a circular ring, a rectangular ring, or other polygonal ring structures.

[0064] In this way, on the one hand, the position of the connection between the adapter 522 and the electrical adapter 521 can be defined, improving the positioning accuracy; on the other hand, the connection between the adapter 522 and the electrical adapter 521 can be prevented from contacting other devices, improving circuit safety, reducing the probability of the connection between the adapter 522 and the electrical adapter 521 being separated by collision, and improving the reliability of the connection between the adapter 522 and the electrical adapter 521.

[0065] like Figures 9-10 As shown, in this embodiment, the battery pack 1 further includes a cover 550, which is detachably connected to the protective protrusion 511, and the cover protects the cavity 5111. The cover 550 is made of insulating material. The protective protrusion 511 and the cover 550 can be connected by snap-fit ​​connection, threaded connection, sliding connection, or other detachable methods.

[0066] This avoids contact between the connection point of the adapter 522 and the electrical adapter 521 and other devices, improves circuit safety, reduces the probability of the connection point of the adapter 522 and the electrical adapter 521 being separated by collision, and improves the reliability of the connection between the adapter 522 and the electrical adapter 521.

[0067] like Figures 9-10 As shown, in the technical solution of this embodiment, the adapter fixing member 522 includes a vertical segment 5221, a first horizontal segment 5222, and a second horizontal segment 5223.

[0068] A vertical segment 5221 extends along the first direction Z and is disposed within the insulating base 510. A first horizontal segment 5222 is disposed along the first direction Z on the side of the insulating base 510 facing the cover plate 110, and is disposed on the side of the vertical segment 5221 along the second direction X facing away from the battery pack 300. The two ends of the first horizontal segment 5222 are respectively connected to the electrical adapter 521 and the vertical segment 5221. A second horizontal segment 5223 is disposed along the first direction Z on the side of the insulating base 510 facing away from the cover plate 110, and is disposed on the side of the vertical segment 5221 along the second direction X facing towards the battery pack 300. The two ends of the second horizontal segment 5223 are respectively connected to the battery adapter 523 and the vertical segment 5221.

[0069] For example, the first horizontal segment 5222 and the electrical adapter 521 are connected by a first bolt 570, which is fixed to the mounting surface 501. The first bolt 570 can be integrally injection molded with the insulating base 510, and then the first nut 571 is threadedly connected to the first bolt 570 to fix the first horizontal segment 5222 and the electrical adapter 521.

[0070] The second horizontal segment 5223 and the battery adapter 523 are connected by a second bolt 580. The second bolt 580 is fixed to the side of the insulating base 510 facing away from the cover plate 110. The second bolt 580 can be integrally injection molded with the insulating base 510, and then threadedly connected to the second bolt 580 by a second nut 581 to fix the second horizontal segment 5223 and the battery adapter 523.

[0071] Thus, the adapter fixing member 522 is constructed with a "Z"-shaped structure. The first horizontal segment 5222 and the electrical adapter member 521 can be fitted together, and the second horizontal segment 5223 and the battery adapter member 523 can be fitted together. This results in a stable connection and requires little space in the thickness direction of the battery pack 1. Furthermore, increasing the extension length of the adapter fixing member 522 helps improve the connection stability between the adapter fixing member 522 and the insulating base 510.

[0072] In addition, the first horizontal segment 5222 extends from the vertical segment 5221 along the second direction X in a direction away from the battery pack 300, and the second horizontal segment 5223 extends from the vertical segment 5221 along the second direction X in a direction closer to the battery pack 300. This facilitates the connection between the first horizontal segment 5222 and the electrical adapter 521, as well as the connection between the second horizontal segment 5223 and the battery adapter 523, reducing the probability of interference and improving the ease of assembly of the adapter assembly 520.

[0073] like Figures 2-5 , Figures 7-9As shown, in this embodiment, the battery pack 1 further includes a slave control module 400, which is disposed in the first receiving cavity 101. The slave control module 400 and the adapter module 800 are disposed on the same side of the battery pack 300 along the second direction X. The battery pack 300 includes a plurality of battery cells 310, and the slave control module 400 is connected to at least one battery cell 310. The adapter module 500 further includes a control adapter 560, which is disposed on the insulating base 510 and penetrates the insulating base 510 along the first direction Z. The control adapter 560 and the adapter assembly 520 are spaced apart. The control adapter 560 is connected between the electrical module 200 and the slave control module 400, that is, one end of the control adapter 560 along the first direction Z is connected to the electrical module 200, and the other end of the control adapter 560 along the first direction Z is connected to the slave control module 400.

[0074] The slave control module 400 is connected to the battery management system (BMS) of the electrical module 200. The slave control module 400 can obtain parameter information such as voltage, current and temperature of the battery pack 300, and then transmit the above parameter information to the battery management system of the electrical module 200 through the control adapter 560, so that the battery management system can adjust the working state of the battery pack 300 in a timely manner according to the above parameter information.

[0075] By incorporating a control adapter 560 in the adapter module 500, there is no need to set up an additional mounting structure for the control adapter 560. This not only enables the connection between the slave control module 400 and the electrical module 200, but also improves the integration level of the adapter module 500.

[0076] like Figure 5 , Figure 7 and Figure 8 As shown, in the technical solution of this embodiment, the battery pack 1 also has a third direction Y intersecting the first direction Z and the second direction X. The adapter module 500 includes two adapter components 520. Both the electrical module 200 and the battery pack 300 have positive and negative terminals. The positive terminals of the electrical module 200 and the battery pack 300 are electrically connected through one adapter component 520, and the negative terminals of the electrical module 200 and the battery pack 300 are electrically connected through the other adapter component 520. The two adapter components 520 are spaced apart along the third direction Y, and the control adapter 560 is located between the two adapter components 520 along the third direction Y.

[0077] By using a control adapter 560 to separate the two adapter components 520, the probability of the two adapter components 520 coming into contact is reduced, thereby avoiding short circuit problems and improving circuit safety.

[0078] like Figures 7-9As shown, in the technical solution of this embodiment, the insulating base 510 includes an integration part 512 and a positioning part 513. An integrated section 512 is disposed at the opening 112 along the first direction Z. A connecting component 520 is provided on the integrated section 512. Specifically, a connecting fixing component 522 and a control connecting component 560 are installed on the integrated section 512. The mounting surface 501 is provided on the side of the integrated section 512 facing the opening 112. A positioning part 513 is disposed on the side of the integrated section 512 facing away from the cover plate 110 along the first direction Z. The positioning part 513 is connected to the side of the integrated section 512 facing away from the cover plate 110 along the first direction Z. The first housing 100 includes a frame 130 and a bottom support plate 140. The cover plate 110 and the bottom support plate 140 are respectively connected to opposite sides of the frame 130 along the first direction Z. The cover plate 110, the frame 130 and the bottom support plate 140 together form a first receiving cavity 101. The positioning part 513 is connected to the side of the frame 130 facing the battery pack 300.

[0079] Specifically, the positioning part 513 includes an integrally formed positioning plate 5131, mounting plate 5132, and support plate 5133. The positioning plate 5131 is connected to the side of the frame 130 facing the battery pack 300 along the second direction X. The positioning plate 5131 and the frame 130 can be connected by snap-fit ​​or bolt. The mounting plate 5132 is connected to the integration part 512 along the first direction Z along the side facing the cover plate 110. The mounting plate 5132 has an opening 5134.

The support plate 5133 is located on opposite sides of the mounting plate 5132 along the third direction Y. The support plate 5133 is inclined along the second direction X along the side facing the positioning plate 5131.

[0080] The integration part 512 and the adapter fastener 522 can be integrally injection molded, with the adapter fastener 522 integrated into the integration part 512, thereby improving the connection strength between the integration part 512 and the adapter fastener 522.

[0081] By separating the integration part 512 and the positioning part 513, and connecting the positioning part 513 to the first housing 100 and the integration part 512 to the cover plate 110, installation is facilitated. Screws can be passed through the positioning part 513 and the frame 130 in sequence to fix the relative position of the positioning part 513 and the first housing 100. Then, the integration part 512 is connected to the positioning part 513, avoiding interference between the integration part 512, the adapter fixing part 522 or the battery adapter part 523 and the screws. On the other hand, it is beneficial to adjust the relative position of the first housing 100, the positioning part 513, the integration part 512 and the cover plate 110, avoiding the influence of processing errors and improving installation accuracy.

[0082] In addition, the support plate 5133 is triangular in shape, which ensures the structural strength of the support plate 5133 without excessively increasing the material usage of the positioning part 513, thus avoiding increased costs. Furthermore, the mounting plate 5132 has an opening 5134, which avoids interference with the adapter fixing part 522 and the battery adapter part 523, and also reduces costs and weight.

[0083] Secondly, according to an embodiment of the present invention, an electrical device is provided, which includes the aforementioned battery pack 1. The electrical device can be a vehicle or an energy storage device, etc.

[0084] The electrical equipment of this utility model, by utilizing the aforementioned battery pack 1, can increase the capacity of the battery pack 1 while ensuring its normal function.

[0085] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
