The battery module provided by the embodiment includes a frame and a battery cell (not shown in the figure) accommodated in the frame, wherein the frame includes an end plate assembly. As shown in fig. 1 and 2, the end plate assembly includes an end plate 200 and an output pole base 100, and the output pole base 100 is disposed on the end plate 200 for mounting and fixing the output pole. In this embodiment, the frame includes two end plates 200 (only one is shown in the figure) and two side plates (not shown in the figure), the two end plates 200 are arranged in parallel at intervals, the two side plates are arranged in parallel at intervals, two ends of each side plate are respectively connected to the two end plates 200, and the two end plates 200 and the two side plates jointly enclose an accommodating space. In this embodiment, the accommodation space that the frame constitutes can be used to hold the electric core of arranging into a line, and under the condition of holding electric core, end plate 200 is located the leading both ends of electric core queue, and the curb plate is located the both sides of electric core queue.
In the embodiment of the present application, the output pole base 100 is disposed on the end plate 200 of the frame, and particularly, may be disposed on the upper edge of the end plate 200.

In the present embodiment, in a state where the output pole mount 100 is fitted to the connection hole 210, the rotation axis of the rotation connecting part 120 coincides with the axis of the connection hole 210.
In this embodiment, the cross section of the connection hole 210 is polygonal, two adjacent inner side walls 211 of the connection hole 210 form recesses with a certain included angle, and the number of the recesses is consistent with that of the matching bosses 126, so that in the process of inserting the rotary connection part 120 into the connection hole 210, the recesses between the two adjacent inner side walls 211 can accommodate the matching bosses 126 on the rotary connection part 120, and the situation that the insertion cannot be performed cannot be caused.

As can be seen from fig. 4, the number of the jaws 122 is four, and the four jaws 122 of the rotation coupling portion 120 collectively exhibit a square structure, and thus can be inserted into the square coupling hole 210. Four corners of the square structure form four matching bosses 126, when the rotary connecting part 120 is inserted into the connecting hole 210 and rotates, the four matching bosses 126 abut against the inner side wall 211 of the connecting hole 210, and slide relatively while deforming to recover the original shape in the matching groove 220, and at this moment, the matching bosses 126 are in clamping fit with the matching groove 220, so that the output electrode base 100 is fixed.
In this embodiment, the engagement bosses 126 are evenly spaced about the axis of rotation.
Specifically, the latch 122 includes a transition portion 123, a first elastic arm 124 and a second elastic arm 125, the transition portion 123 is connected to the connecting shaft 121, fixed ends of the first elastic arm 124 and the second elastic arm 125 are connected to the transition portion 123, free ends of the first elastic arm 124 and the second elastic arm 125 extend in two directions away from each other, the extending directions are perpendicular to the rotation axis, the free end of the first elastic arm 124 of the latch 122 overlaps with the free end of the second elastic arm 125 of the adjacent latch 122 in the rotation axis direction, and a matching boss 126 is formed together.
In this embodiment, the first elastic arm 124 and the second elastic arm 125 both have elasticity, so the engaging protrusion 126 formed by the free ends of the first elastic arm 124 and the second elastic arm 125 together also has elasticity. As shown in the drawings, the free ends of the first elastic arm 124 and the second elastic arm 125 have rounded chamfers, so that the mating boss 126 formed by the free ends of the first elastic arm 124 and the second elastic arm 125 has a smooth outer profile, which is beneficial to reduce the resistance and wear of the rotation of the rotary connecting part 120, and at the same time, the inner side wall 211 of the connecting hole 210 is not easily worn. In the present embodiment, the engaging protrusions 126 are formed by disposing the claws 122, so that the engaging protrusions 126 have better elasticity and lighter weight (some hollow areas exist between the claws 122, and thus the weight is lighter).
FIG. 5 is a schematic view of an end plate 200 according to an embodiment of the present application; fig. 6 is an enlarged view of a portion VI in fig. 5. As shown in fig. 5 and 6, in the present embodiment, the cross section of the connection hole 210 is square, the connection hole 210 has four inner sidewalls 211 connected in sequence, and each inner sidewall 211 is provided with a matching groove 220 for matching with the four matching bosses 126 of the rotation connection portion 120. It should be understood that in alternative embodiments, the number of the inner side walls 211 and the number of the matching bosses 126 may be set according to requirements, for example, the cross section of the connection hole 210 may also be set to be a regular pentagon, a regular hexagon, etc., and the number of the matching bosses 126 of the rotation connection portion 120 is five or six.
As shown in fig. 6, the fitting groove 220 has a first recess 222 and a second recess 224 therein, the first recess 222 and the second recess 224 are arranged at intervals in the circumferential direction of the axis of the connection hole 210, a transition boss 223 is formed between the first recess 222 and the second recess 224, the first recess 222 is connected to the opening edge of the fitting groove 220 by a guide slope 221, and the first recess 222 is closer to the opening of the fitting groove 220 than the second recess 224 in the depth direction of the fitting groove 220. In this embodiment, when the output pole base 100 is installed, the mating boss 126 passes through the guiding slope 221, the first recess 222 and finally is embedded into the second recess 224 by rotating the output pole base 100.

When the output pole base 100 is further rotated, the engaging projection 126 passes over the transition projection 223 by deformation, and finally is inserted into the second recess 224. The second recess 224 is farther from the opening of the fitting groove 220 than the first recess 222, that is, the second recess 224 is deeper than the first recess 222, and when the fitting projection 126 enters the second recess 224, it will restore the original shape under the elastic action, so as to be snap-fitted with the second recess 224. The presence of the transition boss 223 limits the counter-rotation of the mating boss 126, thereby ensuring stability of the output pole base 100.

When the output pole base 100 is rotated, the matching boss 126 can generate elastic deformation and then is abutted into the matching groove 220, so that clamping is realized. Since the connection hole 210 is a square hole in the present embodiment, the output electrode base 100 rotates in place when rotating 45 °. When the output pole base 100 is rotated into position, the mating slot 220 defines the position of the mating boss 126 and thus the entire output pole base 100.
