[0012] In some embodiments, mounting ears are oppositely provided on two sides of the electric control module along the second direction, and the mounting ears are fixedly mounted on a side of the beam facing the top plate along the first direction.

[0013] In some embodiments, a distance H1 from the mounting ear to the side of the electric control module facing the base plate satisfies: 1 / 3H≤H1≤2 / 3H; wherein H represents the height dimension of the electric control module in the first direction.

[0036] See also Figures 1 to 4The present application provides a battery, including a box body 10, a crossbeam 20, a battery module 30 and an electronic control module 40. The box body 10 has a receiving cavity 11, a bottom plate 12 and a top plate 13. The bottom plate 12 and the top plate 13 respectively serve as the two side walls of the receiving cavity 11 in the first direction X1, that is, the bottom plate 12 and the top plate 13 are arranged at intervals along the first direction X1, and the receiving cavity 11 is located between the bottom plate 12 and the top plate 13. The crossbeam 20 is received in the receiving cavity 11 and is fixedly connected to the side of the bottom plate 12 facing the top plate 13 along the first direction X1. The crossbeam 20 divides the receiving cavity 11 into a first sub-receiving cavity 110 and a second sub-receiving cavity 112, and the battery module 30 is provided in each of the first sub-receiving cavity 110 and the second sub-receiving cavity 112. A recessed plug-in slot 21 (see FIG. 2 ) is provided on the surface of the side of the crossbeam 20 facing the top plate 13 along the first direction X1. Figure 5 ). Part of the electronic control module 40 is inserted into the insertion slot 21, and the remaining portion of the electronic control module 40 protrudes between the crossbeam 20 and the top plate 13. The distance between the electronic control module 40 and the top plate 13 is greater than or equal to the distance between the battery module 30 and the top plate 13. It should be noted that the electronic control module 40 can be a BMS (Battery Management System). Of course, in other embodiments, the electronic control module 40 can also be other electrical components, which is not limited here.

[0037] The battery described above utilizes the insertion slots 21 on the crossbeam 20 to mount the electronic control module 40. The existing space between the crossbeam 20 and the top plate 13 accommodates the portion of the electronic control module 40 outside the insertion slots 21. Furthermore, the spacing between the electronic control module 40 and the top plate 13 is greater than or equal to the spacing between the battery module 30 and the top plate 13. This eliminates the need to increase the height of the housing 10 in the first direction X1. This eliminates the need to reserve additional space within the housing 10 for mounting the electronic control module 40, significantly improving space utilization within the housing 10 and facilitating higher volumetric capacity density of the battery.

[0038] It should be noted that since the crossbeam 20 is located between the first sub-containment cavity 110 and the second sub-containment cavity 112, the electronic control module 40 is installed on the crossbeam 20, so that the electronic control module 40 is roughly located in the middle of the box body 10, avoiding the electronic control module 40 being located at the edge of the box body 10, thereby avoiding the phenomenon of the electronic control module 40 being damaged due to collision of the box body 10, which is beneficial to improving the safety and reliability of the electronic control module 40.

[0039] It should also be noted that the number of the beams 20 can be one or more, and the number of the electronic control modules 40 can also be one or more, which is not limited here. Figure 1In the illustrated embodiment, there is one crossbeam 20 and two electronic control modules 40. Two insertion slots 21 are defined on one side of the crossbeam 20, along the first direction X1, facing the top plate 13. These two insertion slots 21 are spaced apart along the longitudinal extension of the crossbeam 20 (i.e., the second direction X2). The two electronic control modules 40 are inserted into these two insertion slots 21, respectively.

[0040] Specifically, in this embodiment, the crossbeam 20 extends longitudinally along the second direction X2 and is fixedly connected to the bottom plate 12 of the housing 10. The first sub-cavity 110 and the second sub-cavity 112 are located on either side of the crossbeam 20 in the third direction X3. That is, the first sub-cavity 110, the crossbeam 20, and the second sub-cavity 112 are arranged sequentially along the third direction X3. The first, second, and third directions X1, X2, and X3 are perpendicular to each other. In the third direction X3, the width of the plug slot 21 is at least 6 mm larger than the width of the electronic control module 40. In the second direction X2, the length of the plug slot 21 is at least 14 mm larger than the length of the electronic control module 40. By designing the plug slot 21 to be sufficiently wide in the third direction X3 and sufficiently long in the second direction X2, the electronic control module 40 can be smoothly inserted into the plug slot 21, avoiding insertion difficulties and significantly reducing assembly difficulty.

[0041] Specifically in the embodiment, the box body 10 also includes multiple side panels 14, each of which is connected between the top panel 13 and the bottom panel 12, and is connected in sequence, so that each side panel 14, the top panel 13 and the bottom panel 12 together enclose the above-mentioned receiving cavity 11.

[0042] See Figures 5 to 8 Specifically, in this embodiment, the electronic control module 40 is provided with mounting ears 41 on both sides thereof in the second direction X2. Each mounting ear 41 is fixedly mounted on the side of the crossbeam 20 facing the top plate 13 along the first direction X1. Thus, the electronic control module 40 is fixedly connected to the side of the crossbeam 20 facing the top plate 13 via the mounting ears 41 on both sides thereof in the second direction X2, thereby securing the electronic control module 40 relative to the crossbeam 20 and thus achieving assembly between the electronic control module 40 and the crossbeam 20.

[0043] Optionally, each mounting ear 41 is fixed to the side surface of the crossbeam 20 facing the top plate 13 by screws. Specifically, the mounting ear 41 has a mounting hole for the screw to pass through, and the side of the crossbeam 20 facing the top plate 13 has a threaded hole. The screw is passed through the mounting hole of the mounting ear 41 and is threaded into the threaded hole, so that when the screw is tightened, the mounting ear 41 can be locked and fixed to the crossbeam 20.

[0044] It is understandable that the mounting ear 41 is not limited to being fixed by screws. In other embodiments, the mounting ear 41 can also be fixed to the beam 20 by, for example, a snap-fit ​​method. As long as the mounting ear 41 and the beam 20 can be fixed, no limitation is made here.

[0045] It should be noted that the inventors have discovered that the depth to which the electronic control module 40 is inserted into the insertion slot 21 significantly impacts the stability of the connection between the electronic control module 40 and the crossbar 20. To ensure the required stability of the connection between the electronic control module 40 and the crossbar 20, in some embodiments, the distance H1 from each mounting ear 41 to the side of the electronic control module 40 facing the base plate 12 satisfies the following: 1 / 3H ≤ H1 ≤ 2 / 3H, where H represents the height of the electronic control module 40 in the first direction X1. In other words, the insertion depth of the electronic control module 40 into the insertion slot 21 is between 1 / 3 and 2 / 3 of the total height of the electronic control module 40 (i.e., the height in the first direction X1), which helps ensure the required stability of the connection between the electronic control module 40 and the crossbar 20.

[0046] Furthermore, the electronic control module 40 is provided with an orientation mark, which is used to identify the end of the electronic control module 40 for insertion into the insertion slot 21, thereby preventing the electronic control module 40 from being inserted upside down during assembly. It should be noted that the orientation mark can be an arrow, or of course, other graphics that can serve as an identification function, and this is not limited here.

[0047] Furthermore, the battery also includes reinforcing ribs 42 fixedly connected to the electronic control module 40 and the mounting ears 41 respectively, so that the strength of the mounting ears 41 is reinforced by the reinforcing ribs 42, thereby avoiding the electronic control module 40 from shaking significantly relative to the crossbeam 20 or even the mounting ears 41 from breaking during use, thereby further improving the stability of the connection between the electronic control module 40 and the crossbeam 20.

[0048] It should be noted that reinforcing ribs 42 are provided on both sides of the electric control module 40 in the second direction X2, so as to respectively reinforce the mounting ears 41 on both sides of the electric control module 40 in the second direction X2.

[0049] Optionally, a thickness dimension T of each reinforcing rib 42 along the third direction X3 satisfies: 1.5 mm≤T≤2.5 mm, thereby further enhancing the reinforcing effect of the reinforcing rib 42 on the mounting ear 41 .

[0050] Furthermore, there are multiple reinforcing ribs 42 connected to the same mounting ear 41, and the multiple reinforcing ribs 42 are arranged at intervals along the third direction X3. In other words, each mounting ear 41 is reinforced by multiple reinforcing ribs 42 arranged at intervals along the third direction X3, further ensuring the reinforcing effect of the mounting ear 41. Figure 4In the embodiment shown, the number of reinforcing ribs 42 for reinforcing the same mounting ear 41 is four, that is, four reinforcing ribs 42 are provided on both sides of the electronic control module 40 in the second direction X2, respectively reinforcing the mounting ears 41 located on both sides of the electronic control module 40 in the second direction X2.

[0051] In the embodiment of the present application, the electric control module 40 is provided with a connector 43 on at least one side in the third direction X3, and the connector 43 is located on the portion of the electric control module 40 outside the plug slot 21. The battery further includes a wiring harness 50 (see FIG. 1 ) arranged in the receiving cavity 11 (i.e., in the first sub-receiving cavity 110 and / or the second sub-receiving cavity 112). Figure 4 ), the wiring harness 50 is plugged into the connector 43, thereby electrically connecting the electronic control module 40 to the wiring harness 50 via the connector 43, thereby enabling the electronic control module 40 to receive various signals (e.g., current signals, voltage signals, temperature signals, etc.) transmitted by the wiring harness 50. In this way, the space between the electronic control module 40 and the battery module 30 is utilized to accommodate the connector 43, eliminating the need to reserve additional space for accommodating the connector 43 and increasing the height of the housing 10 in the first direction X1 to accommodate the connector 43. This further improves the space utilization within the housing 10 and facilitates increasing the volumetric capacity density of the battery.

[0052] It should be noted that, in some embodiments, the electric control module 40 is provided with one or more connectors 43 on both sides in the third direction X3. Figure 5 As shown, one or more connectors 43 are provided on one side of the electric control module 40 in the third direction X3, and no connector 43 is provided on the other side.

[0053] Furthermore, each connector 43 has a plug-in port (not shown) for inserting or removing the wiring harness 50 along the third direction X3. That is, the plug-in port of the connector 43 faces the adjacent battery module 30 along the third direction X3. Thus, because the wiring harness 50 can be inserted into or removed from the plug-in port of the connector 43 along the third direction X3, the connector 43 and the wiring harness 50 connected thereto only occupy the space between the electronic control module 40 and the battery module 30, and do not need to occupy the space between the electronic control module 40 and the top plate 13. Consequently, there is no need to increase the height of the housing 10 in the first direction X1, further improving the space utilization within the housing 10 and facilitating an increase in the volumetric capacity density of the battery.

The electric device includes a battery as described in any of the above embodiments, and the electric device uses the battery as a power source. Specifically, the electric device can be a vehicle, a mobile phone, a portable device, a laptop computer, a ship, a spacecraft, an electric toy, an electric tool, and the like.
