Existing electrode protection structures include an electrode protection cover and an electrode protection seat. The electrode protection cover is mounted on the electrode protection seat, and the predetermined conductive member passes through the electrode protection cover to connect to the positive and negative terminals embedded in the electrode protection seat.

[0003] However, in some existing battery cell modules, when the predetermined conductive member passes through the side wall of the electrode protection cover and is connected to the positive and negative terminals on the electrode protection seat, the predetermined conductive member may interfere with the electrode protection seat or need to be bent.

It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0033] See also Figures 1 to 4 As shown, according to an embodiment of the present application, a battery cell module is provided, which includes an electrode protection structure, and the electrode protection structure includes an electrode protection seat 10 and an electrode protection cover 20.

[0034] The electrode protection base 10 is provided with a wiring portion 12. The electrode protection cover 20 is provided on the electrode protection base 10 and encloses the electrode protection base 10 to form an assembly space 101. The wiring portion 12 is located within the assembly space 101. At least one side wall of the electrode protection cover 20 is provided with an opening for allowing a predetermined conductive member to pass through the assembly space 101. Along the depth direction of the opening, the projection of the position on the wiring portion 12 for connection with the predetermined conductive member is located within the projection of the opening. The predetermined conductive member is inserted into the assembly space 101 along the depth direction of the opening to connect with the wiring portion 12.

[0035] Specifically, the predetermined conductive part can be a copper busbar or a wire. In the existing electrode protection structure, when the predetermined conductive part penetrates into the assembly space 101 from the side wall of the electrode protection cover 20, the projection of the position on the wiring portion 12 for connecting with the predetermined conductive part is not located within the projection surface of the opening in the depth direction of the opening. This causes the predetermined conductive part to interfere with the electrode protection seat 10, or the predetermined conductive part needs to be bent before it can be connected to the wiring portion 12, which may cause damage to the electrode protection seat 10 or the predetermined conductive part.

[0036] In order to overcome the above-mentioned defects, in this embodiment, along the depth direction of the opening, the projection surface of the position where the wiring portion 12 is used to connect with the predetermined conductive member is located within the projection surface of the opening. That is to say, after the predetermined conductive member passes through the opening, it can be directly connected to the wiring portion 12, thereby preventing the predetermined conductive member from interfering with the electrode protection seat 10 or requiring the predetermined conductive member to be bent before it can be connected to the wiring portion 12. It can be understood that this embodiment actually provides at least two solutions, one is to adjust the setting position of the opening on the side wall of the electrode protection cover 20, and the other is to adjust the height direction of the wiring portion 12 and the predetermined conductive member in the electrode protection seat 10 (as shown in the attached figure). Figure 1 The connection position on the Z direction) is arranged so that along the depth direction of the opening, the projection surface of the position where the wiring portion 12 is used to connect with the predetermined conductive part is located within the projection surface of the opening, thereby ensuring that the predetermined conductive part can be directly connected to the wiring portion 12 after entering through the opening.

[0037] Furthermore, the electrode protection cover 20 includes a main body 204, a first side wall 201, a top wall 202 and a second side wall 203. The first side wall 201, the top wall 202 and the second side wall 203 are connected in sequence to form a U-shaped structure. The U-shaped structure is surrounded on the main body 204, and the opening is opened on at least one of the first side wall 201 and the second side wall 203.

[0038] In this embodiment, when an opening is provided on at least one of the first sidewall 201 and the second sidewall 203, the predetermined conductive member can be inserted into the assembly space 101 through the first sidewall 201 or the second sidewall 203. The predetermined conductive member is inserted through the sidewall of the electrode protection cover 20, which can improve the space utilization of the battery cell module to a certain extent. Specifically, the battery cell module includes an end plate and a battery cell assembly. The end plate is used to secure the battery cell assembly, and the electrode protection structure is fixed to the end plate. The direction of the opening of the existing electrode protection cover 20 is the same as the arrangement direction of the battery cells in the battery cell assembly. When the predetermined conductive member is inserted through the opening, the length of the battery cell module along the battery cell arrangement direction is excessively long, thereby reducing the space utilization of the battery cell module. In this embodiment, the opening is provided on at least one of the first sidewall 201 and the second sidewall 203, that is, the direction of the opening is perpendicular to the arrangement direction of the battery cells. Therefore, when the predetermined conductive member is inserted into the assembly space 101 through the opening, the length of the battery cell module along the battery cell arrangement direction does not increase, thereby improving the space utilization of the battery cell module to a certain extent.

[0039] In a specific embodiment, the opening includes a first opening 31 and a second opening 32. The first opening 31 is opened on the first side wall 201, and the second opening 32 is opened on the second side wall 203; Figure 1 The projection plane of the position on the wiring portion 12 for connecting with the predetermined conductive member is located within the projection plane of the first opening 31 and the second opening 32 .

[0040] Specifically, in this embodiment, the first sidewall 201 and the second sidewall 203 are symmetrically arranged, and the first opening 31 and the second opening 32 are respectively provided at the same position on the first sidewall 201 and the second sidewall 203, so as to ensure that, along the first direction, the projection of the position on the wiring portion 12 for connection with the predetermined conductive member is located within the projection plane of the first opening 31 and the second opening 32. Of course, the first opening 31 and the second opening 32 do not need to be symmetrically arranged, and the area of the first opening 31 can be larger or smaller than the area of the second opening 32, as long as the passage between the first opening 31 and the second opening 32 is along the first direction, that is, the projection planes of the first opening 31 and the second opening 32 have an intersecting portion along the first direction.

[0041] Furthermore, the electrode protection cover 20 includes a plate body 22 and ribs 23 . The plate body 22 is laid in the opening, and the ribs 23 are breakably connected between the plate body 22 and the opening.

[0042] Specifically, a plate body 22 and ribs 23 are provided in both the first opening 31 and the second opening 32. When a predetermined conductive part needs to be inserted through the first opening 31, it is only necessary to apply an external force to the plate body 22, and the ribs 23 are broken by the external force, so that the first opening 31 is opened, and the predetermined conductive part can be inserted into the assembly space 101 through the first opening 31. Similarly, when a predetermined conductive part needs to be inserted through the second opening 32, the second opening 32 can be opened in the same manner to allow the predetermined conductive part to be inserted into the assembly space. The provision of the plate body 22 and ribs 23 in this embodiment can improve the protective capability of the electrode protection cover 20 to a certain extent, and prevent external impurities from directly penetrating into the assembly space 101 through the opening, thereby affecting the wiring portion 12. At the same time, by selectively removing the plate body 22 and ribs 23 on the first opening 31 or the second opening 32, the predetermined conductive part can enter the assembly space 101 through different openings and directions.

[0043] As attached Figure 3 and attached Figure 4 As shown, the opening also includes a third opening 33, which is opened on the side of the U-shaped structure away from the main body 204. Along the depth direction of the third opening 33, the projection surface of the position on the wiring portion 12 for connecting with the predetermined conductive member is located within the projection surface of the third opening 33.

[0044] In this embodiment, the predetermined conductive member can also enter the assembly space 101 through the third opening 33. Furthermore, because the electrode protection cover 20 on one side of the third opening 33 is not provided with a sidewall, the predetermined conductive member can directly penetrate into the assembly space 101 and directly connect with the wiring portion 12. Alternatively, in some embodiments, the main body 204 may also have an opening, allowing the predetermined conductive member to penetrate into the assembly space 101 through the main body 204 and directly connect with the wiring portion 12.

[0045] In addition, a limiting portion 21 is provided on the electrode protection cover 20, and the limiting portion 21 abuts against the first surface 11 on the top of the electrode protection seat 10. A boss 111 is provided on the first surface 11, and the position of the wiring portion 12 for connecting with the predetermined conductive part is located on the top surface of the boss 111.

[0046] Specifically, the limiting portion 21 abuts against the first surface 11 to prevent the electrode protection cover 20 from moving too much in the direction close to the electrode protection seat 10, thereby preventing the width of the assembly space 101 along the height direction of the electrode protection structure from being too low. When the width of the assembly space 101 along the height direction is too low, it may cause the assembly space 101 to be unable to accommodate the predetermined conductive part; and when the electrode protection cover 20 moves too much in the height direction, it may cause the projection surface of the connection between the wiring portion 12 and the predetermined conductive part along the depth direction of the opening to not be located within the projection surface of the opening, and ultimately the predetermined conductive part needs to be bent before the predetermined conductive part can be connected to the wiring portion 12. In addition, in this embodiment, the position where the wiring portion 12 is used to connect to the predetermined conductive part is located on the top surface of the boss 111, which means that the electrode protection seat 10 will not be affected by the limiting portion 21, resulting in the projection surface of the connection between the wiring portion 12 and the predetermined conductive part not being located within the projection surface of the opening.

[0047] Furthermore, the distance A between the top surface of the boss 111 and the first surface 11 satisfies the relationship: 2mm≤A≤4mm. When A satisfies the above relationship, the boss 111 has a certain protrusion height, so that the projection surface of the connection portion 12 on the top surface of the boss 111 and the predetermined conductive member is located within the projection surface of the opening. The value of A can be 2mm, 2.5mm, 3mm, 3.5mm, and 4mm. If the distance A between the top surface of the boss 111 and the first surface 11 is less than 2mm, the height of the boss 111 is relatively low, and the action of the limiter 21 may cause the projection surface of the connection portion 12 and the predetermined conductive member to not fall within the projection surface of the opening. If A is greater than 4 mm, the height of the boss 111 is too high. On the one hand, the width of the assembly space 101 along the height direction is too narrow, which may cause the predetermined conductive part to be unable to connect with the wiring portion 12; on the other hand, the height of the boss 111 is too high, and ultimately the projection surface of the connection between the wiring portion 12 and the predetermined conductive part does not fall within the projection surface of the opening. After the predetermined conductive part enters the assembly space 101, the predetermined conductive part needs to be bent before it can be connected to the wiring portion 12.

[0048] Furthermore, the limiting portion 21 includes a bent section 211 . The bent section 211 is disposed on at least one side wall of the electrode protection cover 20 . The bent section 211 extends in a direction close to the electrode protection seat 10 and stops at the first surface 11 .

[0049] Specifically, the first side wall 201 and the second side wall 203 of the electrode protection cover 20 are both provided with a bent section 211. The bent section 211 on the first side wall 201 extends in a direction close to the second side wall 203, and the bent section 211 on the second side wall 203 extends in a direction close to the first side wall 201. The bent sections 211 on the first side wall 201 and the second side wall 203 both abut against the first surface 11, thereby limiting the movement of the electrode protection cover 20 in the height direction. In addition, in this embodiment, the first opening 31 is provided at the top of the first side wall 201, and the second opening 32 is provided at the top of the second side wall 203. The boss 111 extends in the height direction, and along the first direction, the projection surface of the connection between the wiring portion 12 and the predetermined conductive member on the top surface of the boss 111 is located within the projection surface of the first opening 31 and the second opening 32, so as to ensure that the predetermined conductive member can directly connect with the wiring portion 12 after passing through the first opening 31 or the second opening 32 into the assembly space 101.

[0050] Furthermore, a curved surface 112 is provided on a side of the boss 111 opposite to the bent section 211 , and an avoidance gap 113 is defined between the curved surface 112 and the bent section 211 .

[0051] In this embodiment, the outer periphery of the predetermined conductive member is coated with an insulating layer. Since the insulating layer has a certain thickness, when the insulating layer enters the assembly space 101, the insulating layer may interfere with the electrode protection seat 10. To prevent the insulating layer from interfering with the electrode protection seat 10, this embodiment provides an avoidance gap 113 between the arcuate surface 112 and the bent section 211. The avoidance gap 113 is used to avoid the insulating layer, thereby preventing the insulating layer from interfering with the electrode protection seat 10. In addition, the side of the boss 111 opposite the bent section 211 is provided with an arcuate surface 112. When the insulating layer contacts the electrode protection seat 10, the arcuate surface 112 can reduce the friction between the insulating layer and the boss 111, thereby preventing the insulating layer from being subjected to large friction and thus being worn and damaged.

[0052] In addition, the maximum width B of the avoidance gap 113 satisfies the relationship: 1mm≤B≤3mm. When B is less than 1mm, the width of the avoidance gap 113 is too narrow, and interference is likely to occur between the insulating layer and the boss 111. When B is greater than 3mm, the avoidance gap 113 is too large, so that the volume of the boss 111 is set smaller or the extension length of the bending section 211 is too low. On the one hand, it may cause the connection stability between the wiring portion 12 and the predetermined conductive part to be reduced, and on the other hand, it may cause the bending section 211 to be unable to limit the movement of the electrode protection cover 20 in the height direction. When B satisfies the above relationship, the width of the avoidance gap 113 is moderate and will not have too much impact on the size of other bending sections 211 or boss 111. The value of B can be 1mm, 1.5mm, 2mm, 2.5mm and 3mm.

[0053] As attached Figure 2 To the attached Figure 4 As shown, the electrode protection cover 20 is provided with a slot 24, and the electrode protection base 10 is provided with a buckle 13 that adapts to the slot 24. When the bent section 211 abuts the first surface 11, the buckle 13 engages with the slot 24, thereby securing the electrode protection cover 20 to the electrode protection base 10. At this time, along the first direction, the projection of the connection between the wiring portion 12 on the boss 111 and the predetermined conductive member lies within the projection of the first opening 31 and the second opening 32. In some preferred embodiments, the slot 24 and the buckle 13 are both arranged at an angle along the height direction to improve the connection stability between the electrode protection base 10 and the electrode protection cover 20.

[0054] In summary, in the present application, an opening is provided on at least one side wall of the electrode protection cover 20, and along the depth direction of the opening, the projection surface of the connection between the wiring portion 12 and the predetermined conductive part is located at the projection surface of the opening, so that after the predetermined conductive part is inserted into the assembly space 101, interference between the predetermined conductive part and the electrode protection seat 10 is avoided, and at the same time, the predetermined conductive part does not need to be bent before being connected to the wiring portion 12. In addition, in the present application, a bending section 211 is provided on at least one side wall of the electrode protection cover 20, and the bending section 211 abuts against the first surface 11, so that the electrode protection seat 10 limits the electrode protection cover 20 in the height direction. At the same time, the first surface 11 of the electrode protection seat 10 is provided with a boss 111 extending in the height direction, and the projection surface of the connection between the wiring portion 12 and the predetermined conductive part on the boss 111 is located within the projection surface of the opening. In addition, the present application also provides an inclined buckle 13 on the electrode protection seat 10, and a slot 24 adapted to the buckle 13 is provided on the electrode protection cover 20, thereby improving the connection stability of the electrode protection seat 10 and the electrode protection cover 20.

[0055] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures.
