In addition, it should be stated that although the frame components in the foregoing embodiments are formed by a plurality of frame bodies 100 being detachably docked, the present invention is not limited thereto. For example, in other embodiments, a plurality of frames constituting a single frame component may also be formed integrally, that is, a single frame component is formed integrally.

From the above, in the frame body, the frame body assembly, and the battery module disclosed in the present invention, since the side of the frame body having one of the first assembling portions is thicker than the opposite side, or the frame body has the second side The thickness of one side of the assembly portion is thicker than the opposite side, so that the single frame has a difference in thickness in structural design. Therefore, the structural shape of the frame after docking has various changes, and the degree of freedom of combination is high, so that multiple frames can be assembled along different axial directions. For example, the assembling frames of a plurality of frames can be stacked and docked together. For another example, two adjacent frames can be stacked in opposite directions, so that the two first assembling portions of the two frames protrude from the outer edges of the overlapping assembling frames, and the two protruding first assembling portions can be respectively For other frames.

In this way, users can combine multiple frames into corresponding battery modules according to the required power consumption, so as to achieve customized requirements. Of course, the battery module can still be extended to expand more frames to meet the demand for increasing the power supply. In addition, the structure of the battery module has various changes, which can be adjusted in accordance with environmental constraints, so that the shape of the battery module matches the surrounding environment, so as to achieve the purpose of effectively utilizing space.

In addition, the battery module of the present invention can not only be used as a power source, but also can be adaptively used as one of the supporting structures due to its high structural strength. For example, when applied to vehicles such as electric vehicles and electric vehicles, in addition to serving as a source of power, the battery module can also be used as the skeleton of the vehicle body to share the load. As another example, when a large number of frames are overlapped along a horizontal plane to form a battery module wall, it can be laid on a truck to serve as a carrier board for goods on the truck, and can also be used as a partition wall when placed at home. Of course, these are only one of the examples where the frame of the present invention is applicable, and users can make customized adjustments according to actual needs.

Although the present invention is disclosed in the foregoing embodiments, it is not intended to limit the present invention. Changes and modifications made without departing from the spirit and scope of the present invention belong to the patent protection scope of the present invention.
