[0029] In addition, in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and can also be the communication inside two elements. It can be a wireless connection or a wired connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0030] In addition, the technical features involved in different embodiments of the present utility model described subsequently can be combined with each other as long as they do not conflict with each other.

[0031] Such as Figures 1-5, an embodiment of the present utility model provides a hoisting member for use in the assembly and installation of a battery module 3, which can facilitate the hoisting of the product module 2 into the chassis, better save the chassis space, and more firmly hoist the battery module 3 into the chassis, making it more convenient during disassembly and use. The hoisting member is a special-shaped sheet metal part 1 formed by integral stamping. The battery module 3 is tightly assembled through the special-shaped sheet metal part 1, and the special-shaped sheet metal part 1 plays a role in fixing and combining, reducing the gap between the battery modules 3. Specifically, the battery module 3 is usually assembled from a steel strip 6 (metal steel strip, plastic-steel strip), a CCS component (bus bar, sampling line), a terminal block 5, an end plate 4, a PC insulating paper, an EPDM foam, a heating film, and battery cells 7, etc. A number of groups of threaded holes 8 are symmetrically arranged on the outer side surface of the end plate 4, and through holes 9 corresponding to the threaded holes 8 are opened on the front surface of the special-shaped sheet metal part 1. When multiple battery modules 3 are assembled, they are limited by the cooperation of the through holes 9 and the threaded holes 8, and then screwed and fastened to form the product module 2. The special-shaped sheet metal part 1 makes the gap between the assembled battery modules 3 smaller and the modules closer to each other, thereby reducing the assembly volume of the assembled modules and saving the assembly space of the chassis.

[0032] Furthermore, the special-shaped sheet metal part 1 is formed with a first flanging 10 and a second flanging 11 respectively located on the upper and lower sides. The directions of the first flanging 10 and the second flanging 11 are opposite, and both the first flanging 10 and the second flanging 11 are perpendicular to the front plane of the special-shaped sheet metal part 1. The first flanging 10 is used for hoisting the battery module 3 to facilitate the assembly of the module into the interior of the chassis; the second flanging 11 is inserted into the lower part of the end plate 4, so that the second flanging 11 can lift the battery module 3 during hoisting, increasing the strength. Specifically, both ends of the first flanging 10 are formed with bending parts, and the bending parts include a first folding edge 12 and a second folding edge 13 that are continuously bent. The first folding edge 12 and the second folding edge 13 form an L-shaped structure, and the first folding edge 12 is perpendicular to the plane where the first flanging 10 is located. Symmetric first hoisting holes 14 are provided on the first folding edge 12. The first hoisting holes 14 are rectangular holes, and the first hoisting holes 14 are used for hoisting the product module 2. That is, at least two battery modules 3 are assembled through the special-shaped sheet metal part 1 to form the product module 2, and then the hook of the hoisting tool is hung on the first hoisting holes 14 to directly hoist the product module 2 into the chassis, thus completing the assembly. The application of the special-shaped sheet metal part 1 is different from the assembly method in the form of a lifting ring. It does not require the configuration of special hoisting tools and does not require too many hoisting operation steps. The hoisting operation is simpler and more convenient, not only saving the box space but also saving labor and time costs. Preferably, symmetric second mounting holes 15 are provided on the second folding edge 13, and the second mounting holes 15 are used for cooperating with the installation of a protective cover. The protective cover is made of PVC material. When the battery module 3 is assembled into the chassis, a protective cover usually needs to be installed on the upper surface of the product module 2 to prevent the box from contacting the conductive end of the battery cell 7 and causing a short circuit, and at the same time, it can protect the battery module 3 from external force impact.

[0033] Further, in this embodiment, symmetric second lifting holes 16 are also provided on both sides of the end plate 4. The second lifting holes 16 are grooved in the middle of both sides of the end plate 4. The second lifting holes 16 can be used to lift the battery module 3 or the product module 2. That is, when lifting the battery module 3, it is lifted through the second lifting holes 16; when the product module 2 is assembled, it can be lifted through the first lifting holes 14 of the special-shaped sheet metal part 1 or through the second lifting holes 16, and the two lifting methods can be selectively applied as appropriate. When applying the second lifting holes 16 for lifting, the lifting hook can be directly hung on the groove in the middle for lifting; or the lifting bolt can be passed through the second lifting holes 16, and a locking nut is arranged on the groove in the middle to lock the bolt, so as to carry out lifting, and the lifting does not occupy space. The setting of the second lifting holes 16 neither affects the overall appearance nor occupies space, and can also enable the lifting module to have diversified choices.

[0034] Further, in this embodiment, the first flanging 10 is provided with first mounting holes 17 for cooperating with the box body for installation. The product module 2 is fixedly installed inside the box body through the first mounting holes 17. Preferably, an opening groove 18 is arranged at the middle position of the first flanging 10. The opening groove 18 is used for the wire routing of the battery module 3, and the wires of the battery module 3 can be passed through the opening groove 18, which is convenient for assembly.

[0035] Further, in this embodiment, two shallower mounting grooves 19 are arranged on the outer side surface of the end plate 4. The mounting grooves 19 are used for cooperating with the steel belt 6 for installation. The mounting grooves 19 can catch the steel belt 6 to prevent the steel belt 6 from running off and falling off. Preferably, two accommodating grooves 20 are also provided on the end plate 4. The accommodating grooves 20 are used for cooperating with the terminal block 5 for installation. The terminal block 5 is used for assembling conductive terminals to realize the electrical energy output or charging of the battery module 3.

[0036] Further, in this embodiment, an avoidance groove 21 is arranged at the middle position of the second flanging 11. The avoidance groove 21 is used to open the second lifting holes 16, so as to ensure that the second lifting holes 16 located in the middle of the product module 2 can also be applied when necessary, improving the reliability of the module.

[0037] The above embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited by this. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
