Therefore, other examples of the exemplary embodiments may have different values. 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.

[0032] See also Figures 1 to 7 As shown, according to an embodiment of the present application, a battery cell module is provided, which includes an electrode protection structure, including an electrode protection seat 10 and an electrode protection cover 20.

[0033] Among them, the electrode protection seat 10 is provided with at least two guide parts 12 extending in different directions, and the electrode protection cover 20 includes at least two models. The at least two models of electrode protection covers 20 are arranged in a one-to-one correspondence with the at least two guide parts 12, and the electrode protection cover 20 can be selectively covered on the electrode protection seat 10 through the corresponding guide parts 12.

[0034] Compared with the prior art, in this embodiment, at least two guide portions 12 extending in different directions are provided on the electrode protection seat 10, and at least two different types of electrode protection covers 20 can be covered on the electrode protection seat 10 in different directions through their respective corresponding guide portions 12. That is to say, the structure of this embodiment makes the electrode protection cover 20 and the electrode protection seat 10 no longer have a one-to-one corresponding setting relationship. One electrode protection seat 10 can be adapted to at least two different electrode protection covers 20, and the electrode protection seat 10 can be adapted to at least two electrode protection covers 20 covered on the electrode protection seat 10 in different directions, thereby improving the adaptability of the electrode protection seat 10.

[0035] Furthermore, a guide fitting portion 204 is provided on the electrode protection cover 20 , and the guide fitting portion 204 cooperates with the guide portion 12 so as to enable the electrode protection cover 20 to be covered on the electrode protection seat 10 along the extending direction of the guide portion 12 .

[0036] For example, when the electrode protection cover 20 includes two models, the guide matching part 204 of one model is consistent with the extension direction of a guide part 12 on the electrode protection cover 20, and the electrode protection cover 20 can be covered on the electrode protection seat 10 along the extension direction of the guide part 12 through the matching of the guide matching part 204 and the guide part 12; and the guide matching part 204 on the other model of the electrode protection cover 20 is consistent with the extension direction of another guide part 12 on the electrode protection seat 10, and the guide matching part 204 matches the guide part 12 so that the electrode protection cover 20 can be covered on the electrode protection seat 10 along the extension direction of the guide part 12.

[0037] Furthermore, one of the guide matching portion 204 and the guide portion 12 is a guide groove 123 , and the other is a guide rib 2041 .

[0038] In this embodiment, the guide portion 12 is configured as a guide groove 123, and the guide mating portion 204 is configured as a guide rib 2041. When the electrode protection cover 20 needs to be assembled with the electrode protection base 10, the guide rib 2041 is first inserted into the corresponding guide groove 123, and then an external force is applied to the electrode protection cover 20 along the extension direction of the guide groove 123 to ensure that the electrode protection cover 20 is placed on the electrode protection base 10. In this embodiment, the provision of the guide groove 123 and the guide rib 2041 can limit and guide the electrode protection cover 20. Of course, in some embodiments, the guide portion 12 can be configured as a guide rib 2041, and the guide mating portion 204 can be configured as a guide groove 123.

[0039] As attached Figure 4 As shown, the guide groove 123 includes a plug end 120, with a chamfered end provided at the end of the plug end 120. Specifically, the plug end 120 is the end of the guide rib 2041 that first enters the guide groove 123. The chamfered end of the plug end 120 creates a larger opening at the end, facilitating the rapid insertion of the guide rib 2041 into the guide groove 123. Furthermore, the chamfered end of the plug end 120 forms a transition surface at the end of the plug end 120. This means that if the guide rib 2041 is not aligned with the guide groove 123, the chamfered end 120 gradually aligns the guide rib 2041 with the guide groove 123 after an external force is applied to the guide rib 2041.

[0040] Furthermore, the guide portion 12 includes a first guide portion 121 and a second guide portion 122. The first guide portion 121 is provided on the outer peripheral side of the electrode protection seat 10 and extends along the height direction of the electrode protection seat 10 (as shown in FIG. Figure 1The second guide portion 122 is arranged on the outer peripheral side of the electrode protection seat 10 and intersects with the first guide portion 121 at right angles; the electrode protection cover 20 includes a first electrode protection cover 21 and a second electrode protection cover 22, the first electrode protection cover 21 can be selectively covered on the electrode protection seat 10 through the first guide portion 121, and the second electrode protection cover 22 can be selectively covered on the electrode protection seat 10 through the second guide portion 122.

[0041] See attached Figure 3 As shown, in this embodiment, the first guide portion 121 and the second guide portion 122 are both guide grooves 123, and the guide matching portion 204 on the first electrode protection cover 21 is set as a guide rib 2041, which extends along the height direction. When the first electrode protection cover 21 is assembled with the electrode protection seat 10, the guide rib 2041 is passed through the guide groove 123 of the first guide portion 121, and after being subjected to an external force in the height direction, the first electrode protection cover 21 is covered on the electrode protection seat 10; the second The guide mating portion 204 on the electrode protection cover 22 is similarly configured as a guide rib 2041. The guide rib 2041 extends in the same direction as the guide groove 123 of the second guide portion 122. When the second electrode protection cover 22 is assembled with the electrode protection holder 10, the guide rib 2041 penetrates the guide groove 123 of the second guide portion 122, and an external force is applied to the second electrode protection cover 22 in the same direction as the second guide portion 122, thereby securing the second electrode protection cover 22 to the electrode protection holder 10. Of course, in some embodiments, the guide portion 12 may include multiple guide portions 12 extending in other directions, and the electrode protection cover 20 may include multiple models that can be attached to the electrode protection holder 10 in other directions.

[0042] Furthermore, one of the electrode protection seat 10 and the electrode protection cover 20 is provided with a buckle 13 arranged obliquely along the height direction of the electrode protection structure, and the other one is provided with a slot 201 adapted to the buckle 13 .

[0043] As attached Figure 1As shown, in a specific embodiment, a buckle 13 is provided on the electrode protection cover 20, and a slot 201 adapted to the buckle 13 is provided on the electrode protection seat 10. When the electrode protection cover 20 is covered on the electrode protection seat 10, the buckle 13 is snapped into the slot 201, thereby improving the connection stability between the electrode protection seat 10 and the electrode protection cover 20. In addition, in this embodiment, the buckle 13 and the slot 201 are arranged obliquely along the height direction of the electrode protection structure, which means that no matter in which direction the electrode protection cover 20 is covered on the electrode protection cover 20, the contact area between the buckle 13 and the slot 201 in each direction is large, thereby preventing the electrode protection cover 20 from being separated from the electrode protection seat 10 due to a large external force in a certain direction after the electrode protection cover 20 is assembled with the electrode protection seat 10. For example, when the electrode protection cover 20 is subjected to an external force in the height direction, the inclined surface on the buckle 13 will exert a certain supporting force on the slot 201, and the supporting force can be decomposed in the height direction, thereby balancing the external force in the height direction to avoid the electrode protection cover 20 from separating from the electrode protection seat 10.

[0044] In addition, along the height direction of the electrode protection structure, the electrode protection seat 10 includes a main body section 101 and a connecting section 102 that are connected to each other, the guide portion 12 is arranged on the main body section 101, and a connecting buckle 14 is arranged on the connecting section 102, which is used to be clamped on a predetermined structure.

[0045] Specifically, the battery cell module includes an end plate (not shown in the figure) for fixing the electrode, and the electrode protection seat 10 is fixed on the end plate, that is, the predetermined structure is an end plate, and a mounting groove is provided on the end plate, and the connecting section 102 is installed in the mounting groove through the connecting buckle 14. The electrode protection cover 20 is covered on the main body section 101 through the guide portion 12. In a specific embodiment, the first guide portion 121 and the second guide portion 122 are symmetrically provided on the two opposite side walls of the main body section 101, that is, the electrode protection cover 20 can be covered on the electrode protection seat 10 along the height direction or the extension direction of the second guide portion 122 through two symmetrically provided first guide portions 121 or two symmetrically provided second guide portions 122, thereby improving the guiding and limiting effect of the electrode protection seat 10 on the electrode protection cover 20.

[0046] Furthermore, a guide bevel 141 is provided on the side of the connecting buckle 14 facing away from the main section 101. In this embodiment, the guide bevel 141 facilitates the connection between the connecting section 102 and the end plate. That is, after an external force is applied to the connecting section 102 near the end plate, the connecting section 102 passes through the mounting slot on the end plate. At this time, since the guide bevel 141 is provided on the side of the connecting section 102 facing away from the main section 101, excessive friction is not generated between the guide bevel 141 and the mounting slot, thereby facilitating the connecting buckle 14 to be engaged in the mounting slot.

[0047] In addition, the electrode protection seat 10 is provided with a wiring portion 11 , and the electrode protection cover 20 is provided with at least one opening 40 . The opening 40 is used for allowing a predetermined conductive member to pass through so as to connect the predetermined conductive member to the wiring portion 11 .

[0048] Specifically, the predetermined conductive member can be a copper busbar or a conductive cable. After the predetermined conductive member is connected to the wiring portion 11, it is convenient to introduce the current in the battery module into the outside or to allow the external current to enter the battery module. Therefore, in order to avoid the electrode protection cover 20 from interfering with the predetermined conductive member, at least one opening 40 is provided on the electrode protection cover 20 in this embodiment. In a specific embodiment, as shown in the attached Figure 7 As shown, one type of electrode protection cover 20 is provided with three openings 40, wherein two openings 40 are provided with plates 202 and connecting ribs 203. When an external force is applied to the plates 202, the connecting ribs 203 are broken by the force, so that the plates 202 are separated from the openings 40, thereby opening the openings 40. In another specific embodiment, as shown in FIG. Figure 5 As shown, two openings 40 are provided, and the two openings 40 are provided in the same direction.

[0049] In this embodiment, the connecting section 102 is configured as a rectangular column, and includes two connecting clips 14, one located on each of the two opposing side walls of the rectangular column. Since the wiring portion 11 requires a connection hole within the electrode guard 10, which would reduce the strength of the electrode guard 10, the rectangular column configuration in this embodiment improves the structural strength of the electrode guard 10, to a certain extent preventing the connecting section 102 from breaking due to external forces.

[0050] In summary, the present application provides at least two guides 12 extending in different directions on the electrode protection base 10. At least two electrode protection covers 20 can be selectively placed on the electrode protection base 10 via the different guides 12, thereby improving the adaptability of the electrode protection base 10. In addition, one of the electrode protection base 10 and the electrode protection cover 20 is provided with a clip 13 arranged obliquely in the height direction, and the other of the two is provided with a slot 201 adapted to the clip 13, thereby improving the connection strength between the electrode protection base 10 and the electrode protection cover 20.

[0051] 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. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0052] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0053] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
