Optionally, both the first overlapping portion 110 and the second overlapping portion 210 can be elongated structures, and they are at least partially overlapped along the thickness direction (i.e., the Z-axis direction) of the battery housing to form the battery housing.

[0032] In the embodiment of the utility model, the battery rubber frame is set as two-part structure, in the process of assembling battery, according to the specific size of electric core 310, it is assembled to fix electric core 310, thereby adapting different size electric core 310, this can avoid according to the size of electric core 310 first open mould then make battery rubber frame, in this case, the each component of battery rubber frame can be made in batches, avoid frequent mould opening, thereby simplifying the process of making battery rubber frame, can reduce the manufacturing cost of battery rubber frame simultaneously.

[0033] In addition, the battery rubber frame disclosed in the above embodiment can improve the work efficiency of assembling the battery assembly, thereby greatly shortening the assembly cycle of the battery assembly.

[0034] In optional embodiments, the first frame body 100 and the second frame body 200 are each provided with a positioning portion 120 for positioning cooperation with a jig. It should be noted that the jig herein serves as an auxiliary tool for fixing the first frame body 100 and the second frame body 200 during assembly of the battery assembly. The positioning portion 120 is located outside the accommodation space, thereby avoiding interference with the assembly of the electric core 310. The positioning portion 120 of the first frame body 100 and the positioning portion 120 of the second frame body 200 are arranged at intervals along the circumference of the accommodation space. During assembly of the battery assembly, the first frame body 100 and the second frame body 200 are positioned in the mounting groove of the jig, thereby avoiding movement of the two during assembly of the electric core 310 and other structures. This scheme sets the positioning portion 120 on the first frame body 100 and the second frame body 200, so that the positioning portion 120 is positioned in cooperation with the positioning structure in the jig, thereby improving the stability of the battery rubber frame. Of course, a profiling groove can also be formed on the inner wall of the mounting groove of the jig to position the first frame body 100 and the second frame body 200.

[0035] Optionally, the number of the positioning portion 120 of the first frame body 100 and the positioning portion 120 of the second frame body 200 is at least two, and each positioning portion 120 is arranged at intervals along the circumference of the accommodation space. The positioning structure on the jig for positioning cooperation with the positioning portion 120 is set in one-to-one correspondence with the positioning portion 120, thereby improving the stability of the first frame body 100 and the second frame body 200 in the jig.

[0036] Optionally, the positioning portion 120 can be a positioning groove; or in other embodiments, the positioning portion 120 is a protruding portion, and a positioning groove can be formed on the jig, and the protruding portion and the positioning groove are positioned and matched; further optionally, the positioning portion 120 is provided with a positioning hole 121 for positioning and matching with a positioning column of the jig, that is, the positioning hole 121 is formed on the positioning portion 120, and the positioning portion 120 is sleeved on the positioning column of the jig through the positioning hole 121, so as to position the first frame body 100 and the second frame body 200. The positioning portion 120 adopting this structure is simple in structure and convenient to process and manufacture. Of course, the positioning portion 120 can also be provided with a positioning column, which can be used to be at least partially inserted into the positioning hole of the jig.

[0037] Optionally, the positioning portion 120 can be located on one side of the battery rubber frame facing the groove bottom of the mounting groove of the jig; or in another embodiment, the center axis of the positioning hole 121 is parallel to the thickness direction of the battery rubber frame, that is, the positioning portion 120 is located on one side of the battery rubber frame facing the side wall of the mounting groove of the jig, which can avoid the positioning portion 120 occupying the space in the thickness direction of the battery rubber frame. At this time, the entire battery rubber frame is in a flat plate structure, which is beneficial to reduce the thickness of the battery assembly.

[0038] In still another optional embodiment, the positioning portion 120 can be a block structure, or the positioning portion 120 includes a first side plate 122, a second side plate 123 and a connecting plate 124, the first side plate 122 and the second side plate 123 are oppositely arranged, and the connecting plate 124 is connected between the first side plate 122 and the second side plate 123, and the positioning hole 121 is formed in the connecting plate 124.

Optionally, when the first frame body 100 and the second frame body 200 are both placed in the mounting groove of the jig, the guide inclined surface faces one side of the groove bottom of the mounting groove of the jig, and the connecting plate 124 is connected to one end of the first side plate 122 and the second side plate 123 away from the groove bottom of the mounting groove of the jig. The positioning portion 120 adopting this structure has each component structure in a plate structure, and each has a relatively thin thickness, which can avoid shrinkage phenomenon due to a relatively large thickness of glue during the process of manufacturing the positioning portion 120, thereby improving the structural strength of the positioning portion 120. Meanwhile, when each structure has a relatively thin thickness, it can accelerate the solidification of the glue during the process of manufacturing the positioning portion 120. In addition, the guide inclined surface can play a guiding role to facilitate the placement of the first frame body 100 and the second frame body 200 in the mounting groove of the jig.

[0039] Optionally, the connecting plate 124 is provided with at least two grooves 124a, and each groove 124a is arranged in sequence and spaced around the positioning hole 121. Each groove 124a is used to reduce the thickness of the connecting plate 124, thereby avoiding shrinkage phenomenon due to a relatively large thickness of glue during the process of manufacturing the positioning portion 120, which can further improve the structural strength of the connecting plate 124.

Of course, the positioning part 120 can be arranged on the first lap part 110 and / or the second lap part 210.

[0041] Optionally, the first lap part 110 is flush with the second main body part 220, here, the flush specifically means that when the first frame body 100 and the second frame body 200 are placed in the installation groove of the jig, the top surface (i.e. the surface away from the groove bottom) of the first lap part 110, the outer side surface and the inner side surface of the first lap part 110 are flush with the second main body part 220; the second lap part 210 is flush with the first main body part 130, here, the flush specifically means that when the first frame body 100 and the second frame body 200 are placed in the installation groove of the jig, the bottom surface (i.e. the surface facing the groove bottom) of the second lap part 210, the outer side surface and the inner side surface of the second lap part 210 are flush with the first main body part 130, at this time, the appearance consistency of the entire battery rubber frame is good, which is convenient for being attached with the battery cell 310, the first protective rubber paper 340, the second protective rubber paper 350 and the like, thereby improving the structural compactness of the battery assembly.

[0042] In an alternative embodiment, the extending direction of the first lap joint 110 is parallel to the extending direction of the second lap joint 210, and both sides of the first lap joint 110 opposite to the second lap joint 210 can be flat surfaces, and the two are fixed by friction; or, one side of the first lap joint 110 facing the second lap joint 210 is provided with a plurality of positioning protrusions 111, each of which is arranged in sequence along the extending direction of the first lap joint 110, and one side of the second lap joint 210 facing the first lap joint 110 is provided with a plurality of positioning recesses 211, each of which is arranged in sequence along the extending direction of the second lap joint 210, and at least one positioning protrusion 111 is positioned and matched with at least one positioning recess 211. According to the size of the battery cell 310, the number of positioning protrusions 111 and positioning recesses 211 that are positioned and matched can be flexibly selected. When the size of the battery cell 310 is small, the number of positioning protrusions 111 and positioning recesses 211 that are positioned and matched can be more; when the size of the battery cell 310 is large, the number of positioning protrusions 111 and positioning recesses 211 that are positioned and matched can be less, i.e. can be selected according to actual needs.
