It should be noted that: Similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0032] See Figures 1 to 6 As shown, according to an embodiment of the present application, a battery module is provided, and a battery protection cover is provided on the battery module. The battery protection cover includes a main body 10 and an electrode protection cover 30.

[0033] Among them, an electrode protection seat 20 is provided on the main body 10. The electrode protection cover 30 is detachably connected to the electrode protection seat 20, and a disassembly part 32 is provided on the electrode protection cover. A first connection part 21 is provided on the electrode protection seat 20, and a second connection part 31 detachably connected to the first connection part 21 is provided on the electrode protection cover 30. The second connection part 31 has a first state of being connected to the first connection part 21 and a second state of being separated from the first connection part 21. The disassembly part 32 is connected to the second connection part 31, and the disassembly part 32 is subjected to an external force to cause the second connection part 31 to switch between the first state and the second state.

[0034] Specifically, the electrode protection seat 20 includes a positive electrode protection seat 201 and a negative electrode protection seat 202, and the electrode protection cover 30 includes a positive electrode protection cover 301 and a negative electrode protection cover 302. The positive electrode protection cover 301 is detachably connected to the positive electrode protection seat 201 to protect the positive electrode of the battery. The negative electrode protection cover 302 is detachably connected to the negative electrode protection seat 202 to protect the negative electrode of the battery, thereby preventing an operator from touching the positive or negative electrode of the battery during operation of the battery module, causing unnecessary injuries.

[0035] In addition, after the electrode protection seat 20 or the electrode protection cover 30 is damaged, maintenance of the electrode protection seat 20 or the electrode protection cover 30 is required. Since the existing electrode protection cover 30 and the electrode protection seat 20 are usually fixed with screws, it is time-consuming and laborious to disassemble the electrode protection cover 30. In this embodiment, a disassembly part 32 is provided on the electrode protection cover 30, and the disassembly part 32 is connected to the second connection part 31. After the disassembly part 32 is subjected to an external force, the second connection part 31 and the first connection part 21 are switched between a first state and a second state. This means that when the staff needs to disassemble the electrode protection cover 30 from the electrode protection seat 20, only an external force needs to be applied to the disassembly part 32, and the electrode protection cover 30 can be removed. When the electrode protection cover 30 needs to be installed on the electrode protection seat 20, the staff only needs to apply an external force to the disassembly part 32, move the first connection part 21 to a position corresponding to the second connection part 31, and then remove the external force to connect the first connection part 21 and the second connection part 31, and the installation of the electrode protection cover 30 can be completed. The structure of this embodiment improves the assembly efficiency of the electrode protection seat 20 and the electrode protection cover 30 to a certain extent.

[0036] As shown in the attached Figure 5 to the attached Figure 6 figure, the disassembly part 32 includes a protruding section 321. The first end of the protruding section 321 is connected to the second connection part 31, and the second end of the protruding section 321 extends in a direction away from the second connection part 31.

[0037] Specifically, when an external force in the direction from the outside to the inside of the electrode protection cover 30 is applied to the protruding section 321, the protruding section 321 approaches the electrode protection cover 30 under the action of the external force, and the second connection part 31 moves in a direction opposite to the movement direction of the protruding section 321 under the drive of the protruding section 321, so that the second connection part 31 is separated from the first connection part 21, thereby completing the disassembly of the electrode protection cover 30. On the contrary, when the electrode protection cover 30 needs to be installed on the electrode protection seat 20, an external force in the direction from the outside to the inside of the electrode protection cover 30 is also applied to the electrode protection cover 30. After moving the first connection part 21 of the electrode protection cover 30 to a position opposite to the second connection part 31 on the electrode protection seat 20, the external force applied to the disassembly part 32 is stopped. At this time, the second connection part 31 moves to the original position and is connected to the first connection part 21, thereby completing the installation of the electrode protection cover 30 and the electrode protection seat 20.

[0038] Further, the extension length A of the protruding section 321 away from the second connection part 31 satisfies the relational expression 9mm ≤ A ≤ 13mm.

[0039] Specifically, the convex section 321 is used for an operator to apply an external force. If the extension length of the convex section 321 away from the second connecting portion 31 is too short, such as when A is less than 9 mm, it is difficult for the operator to apply a force to the convex section 321, thereby affecting the assembly of the electrode protection cover 30 and the electrode protection seat 20. When A is greater than 13 mm, the extension length of the convex section 321 away from the second connecting portion 31 is too long. Since there are other components in the battery module, interference may occur between the convex section 321 and other components, resulting in damage to other components or the convex section 321. When A satisfies the relation 9 mm ≤ A ≤ 13 mm, the convex section 321 will not interfere with other components, and it is easy for the operator to apply an external force to the convex section 321. The value of A can be 9 mm, 9.5 mm, 10 mm, 10.5 mm, 11 mm, 11.5 mm, 12 mm, 12.5 mm, and 13 mm.

[0040] Further, a rib 322 is provided on the convex section 321.

[0041] Specifically, the rib 322 is used to increase the friction between the operator and the convex section 321, preventing the operator from slipping when applying a force to the convex section 321. In addition, there are multiple ribs 322, and the multiple ribs 322 are arranged at intervals along the extension direction of the convex section 321 away from the second connecting portion 31. In a specific embodiment, the extension direction of the rib 322 is perpendicular to the extension direction of the convex section 321 away from the second connecting portion 31. Of course, the extension direction of the rib 322 can also be the same as the extension direction of the convex section 321 away from the second connecting portion 31.

[0042] Further, both the first connecting portion 21 and the second connecting portion 31 include the same even number. The even number of first connecting portions 21 are symmetrically arranged on the outer peripheral side wall of the electrode protection seat 20 along the center of the electrode protection seat 20, and the even number of second connecting portions 31 are symmetrically arranged on the outer peripheral side wall of the electrode protection cover 30 along the center of the electrode protection cover 30.

[0043] Specifically, the setting method of this embodiment can enable the electrode protection cover 30 to still be buckled on the electrode protection seat 20 after rotating a certain angle, thereby improving the applicability of the electrode protection cover 30. As shown in Figure 5 to Figure 6As shown, in a specific embodiment, there are four second connecting parts 31, and the four second connecting parts 31 are symmetrically arranged in pairs along the center of the electrode protection cover 30 on two opposite outer peripheral side walls of the electrode protection cover 30; there are four first connecting parts 21, and the four first connecting parts 21 are symmetrically arranged in pairs along the center of the electrode protection cover 30 on two opposite outer peripheral side walls of the electrode protection seat 20, so that the electrode protection cover 30 can still be buckled with the electrode protection seat 20 after rotating 180°. Optionally, both the first connecting part 21 and the second connecting part 31 can be set to 2, 4, 6, and 8.

[0044] In addition, the disassembly part 32 includes an even number, and the even number of disassembly parts 32 are connected to the even number of second connecting parts 31 in one-to-one correspondence.

[0045] Specifically, an even number of convex segments 321 are arranged in one-to-one correspondence with the even number of second connecting parts 31. When an operator needs to separate the first connecting part 21 and the second connecting part 31 symmetrically arranged on two side walls, an external force can be applied to the two symmetrically arranged convex segments 321 at the same time. In addition, the even number of symmetrically arranged convex segments 321 also facilitate the operator to apply an external force, that is, the electrode protection cover 30 can be disassembled from the electrode protection seat 20 by two fingers.

[0046] In addition, an installation groove 23 is provided in the electrode protection seat 20, and the installation groove 23 is used to install the positive electrode or the negative electrode of the battery. The setting of the installation groove 23 reduces the structural strength of the electrode protection seat 20. Therefore, in this embodiment, in order to improve the structural strength of the electrode protection seat 20 and extend the service life of the electrode protection seat 20. In this embodiment, a plurality of reinforcing ribs 22 are provided at intervals between the outer peripheral side wall of the electrode protection seat 20 and the main body 10.

[0047] Further, a plurality of avoidance parts 33 corresponding to the plurality of reinforcing ribs 22 are provided at intervals on the outer peripheral side wall of the electrode protection cover 30.

[0048] Specifically, since a plurality of reinforcing ribs 22 are provided on the outer periphery of the electrode protection seat 20, when the electrode protection seat 20 is connected to the electrode protection cover 30, it may cause interference between the electrode protection cover 30 and the electrode protection seat 20. Therefore, in this embodiment, a plurality of avoidance parts 33 are provided on the electrode protection cover 30, so that after the electrode protection cover 30 is covered on the electrode protection seat 20, the electrode protection cover 30 will not interfere with the electrode protection seat 20.

[0049] Further, one of the first connecting part 21 and the second connecting part 31 is a limiting groove 311, and the other is a limiting convex block 211. In this embodiment, through the structure of the limiting convex block 211 and the limiting groove 311, the electrode protection cover 30 is installed on the electrode protection seat 20. As attached Figure 4As shown, in a specific embodiment, a limiting bump 211 is provided on the electrode protection seat 20, and a limiting groove 311 is provided on the outer peripheral side wall of the electrode protection cover 30. The limiting groove 311 is connected to the protruding section 321.

[0050] In addition, one side of the limiting bump 211 close to and / or away from the electrode protection cover 30 is provided with an inclined surface, which is convenient for the limiting bump 211 to penetrate into the limiting groove 311, thereby improving the assembly efficiency of the electrode protection seat 20 and the electrode protection cover 30.

[0051] Furthermore, recessed portions 24 are provided on both opposite side walls of the electrode protection seat 20 where the limiting bumps 211 are not provided. When the electrode protection cover 30 is covered on the electrode protection seat 20, the recessed portions 24 and the mounting groove 23 form a through hole for a copper row (not shown in the figure) to pass through.

[0052] In addition, in this embodiment, a first identification portion 11 is provided on the main body 10, and a second identification portion 34 is provided on the electrode protection cover 30. The first identification portion 11 is used to identify the positive electrode protection seat 201 and the negative electrode protection seat 202, and the second identification portion 34 is used to identify the positive electrode protection cover 301 and the negative electrode protection cover 302. The first identification portion 11 and the second identification portion 34 are used in cooperation to improve the distinguishability between the positive electrode and the negative electrode.

[0053] For the sake of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper...", etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure of the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will be positioned as "below other devices or structures" or "under other devices or structures" afterwards. Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0054] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional statements, the above words have no special meanings, so they cannot be understood as limiting the protection scope of this application.

[0055] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
